In order to more clearly illustrate the technical solution in the embodiments of the disclosure, the drawings that are needed in the description of the embodiments will be briefly described in the following. It is obvious that the drawings in the following description are merely some embodiments of the disclosure, and for one skilled person in the art, other drawings can be obtained according to these drawings.

Hereinafter, the technical solutions in the embodiments of the disclosure will be clearly and completely described with reference to the accompanying drawings in the embodiments of the disclosure, and it is apparent that the described embodiments merely are a portion of but not all of the embodiments of the disclosure. All other embodiments, which can be derived by one of ordinary skill in the art based on the embodiments disclosed herein, are within the scope of the disclosure.

In the description of the disclosure, it should be understood that orientation or position relations indicated by the terms of "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like are based on the orientation or position relations shown in the drawings, only for the purpose of facilitating and simplifying description of the present invention, and they do not indicate or imply that the device or element referred must have a specific orientation or be constructed and operated in a specific orientation, and thus they cannot be construed as limiting the disclosure.

In the description of the disclosure, what needs to be explained is that, unless specified and defined otherwise, the terms "mount", "join" and "connect" should be construed in a broad sense, for example, as fixedly connecting, a removable connecting or integrally connecting. For a person skilled in the art, the specific meanings of the above terms in the present disclosure can be understood in specific situations.

The terms "first", "second" and "third" are only used for description purpose and cannot be construed as indicating or implying a relative importance or implicitly indicating the number of the technical features indicated. Thereby, features defined by "first", "second" or "third" may explicitly or implicitly comprise one or more such features. Unless otherwise specified, "a plurality" means two or more in the description of the disclosure.

In the display device of related art, between the rear housing and the backplane are connected by screws to achieve relative fixation between the rear housing and the backplane. However, the rear housing and the backplane are connected by screws, and the screws need to be screwed one by one when the rear housing and the backplane are assembled or disassembled, which takes a long time and reduces the assembly and disassembly efficiency between the rear housing and the backplane.

As shown in <FIG>, some embodiments of the disclosure provide a mounting structure for a rear housing of a display device, the mounting structure including a backplane <NUM> and a rear housing <NUM>. Referring to <FIG>, the backplane <NUM> includes a backplane substrate <NUM> and a first engaging structure <NUM>, the first engaging structure <NUM> is disposed on one side of the backplane substrate <NUM>, for example, on a side of the backplane substrate <NUM> facing the rear housing <NUM>. Referring to <FIG>, the rear housing <NUM> includes a rear housing substrate <NUM> and a second engaging structure <NUM>, the second engaging structure <NUM> is disposed on one side of the rear housing substrate <NUM>, for example, on a side of the rear housing substrate <NUM> facing the backplane <NUM>.

The first engaging structure <NUM> matches with the second engaging structure <NUM>, and the two structures can be engaged with each other. By engaging the first engaging structure <NUM> and the second engaging structure <NUM> together, the backplane <NUM> and the rear housing <NUM> can be fixed relatively.

It is noted that the backplane <NUM> refers to the backplane <NUM> of the backlight module in the display device. Generally, a display device includes a display panel, a backlight module, and a rear housing <NUM>; the backlight module is disposed on one side of the display panel opposite to the display surface of the display panel, and the backplane <NUM> of the backlight module is located on a side away from the display panel relative to the optical film material of the backlight module; the rear housing <NUM> is disposed on a side of the backlight module away from the display panel. Through the mounting structure for the rear housing of the display device, the rear housing <NUM> can be engaged and fixed with the backplane <NUM> of the backlight module, so that the firmness and the reliability of the assembled display device are improved.

In the mounting structure for the rear housing of the display device provided by above mentioned embodiments of the disclosure, the first engaging structure <NUM> and the second engaging structure <NUM> are engaged with each other, so that the rear housing <NUM> and the backplane <NUM> are relatively fixed, and when the rear housing <NUM> is assembled with the backplane <NUM>, the engaging between the rear housing <NUM> and the backplane <NUM> can be achieved by directly applying a force to the backplane <NUM> or the rear housing <NUM>, thereby completing the assembly between the rear housing <NUM> and the backplane <NUM>. This procedure is simple and quick, and does not require tightening screws, so that a large amount of time can be saved, which is beneficial to improving the assembly efficiency between the rear housing <NUM> and the backplane <NUM> of the display device.

The first engaging structure <NUM> and the second engaging structure <NUM> may have various structures. In some embodiments, referring to <FIG>, the first engaging structure <NUM> includes at least two engaging beams <NUM>, and the second engaging structure <NUM> includes at least two engaging hooks <NUM>, and the at least two engaging beams <NUM> are correspondingly engaged with the at least two engaging hooks <NUM>, respectively, so that the rear housing <NUM> and the backplane <NUM> are relatively fixed. In this way, after the rear housing <NUM> and the backplane <NUM> are relatively fixed, the firmness and reliability between the rear housing <NUM> and the backplane <NUM> can be further improved.

The engaging beams <NUM> can be disposed in a variety of ways, including but not limited to the various possible designs shown below.

In some possible designs, as shown in <FIG>, each engaging beam <NUM> of the at least two engaging beams <NUM> includes an engaging beam body <NUM>' and two hollow portions <NUM>', the two hollow portions <NUM>' are two spaced openings formed on the backplane substrate <NUM>, and the backplane substrate <NUM> between the two hollow portions <NUM>' forms the engaging beam body <NUM>'.

As shown in <FIG>, during the process of engaging, the engaging hook <NUM> corresponding to the engaging beam <NUM> passes through the hollow portion <NUM>' of the engaging beam <NUM>, hooking the engaging beam body <NUM>' of the engaging beam <NUM>, so as to realize the engaging of the engaging beam <NUM> and the engaging hook <NUM>.

Through such a design, the engaging beam <NUM> can be integrally formed with the backplane substrate <NUM>, that is, the backplane <NUM> is an integrated structure, so that the structure of the backplane <NUM> can be simplified.

In some other possible designs, as shown in <FIG>, the first engaging structure <NUM> includes at least two groups of connecting structures <NUM> in addition to at least two engaging beams <NUM>. The at least two groups of connecting structures <NUM> are disposed on the backplane substrate <NUM>, and the at least two engaging beams <NUM> are fixed on the backplane substrate <NUM> through the at least two groups of connecting structures <NUM>, respectively. In this way, when the engaging beam <NUM> is damaged, the engaging beam <NUM> can be replaced by detaching the engaging beam <NUM> from the connecting structure <NUM>, so that the maintenance cost can be reduced.

Exemplarily, each engaging beam <NUM> of the at least two engaging beams <NUM> is a metal rod or a metal wire (such as a steel wire or the like), and the metal rod or the metal wire can be disposed according to specific actual situations and will not be particularly defined herein.

Herein, the connection structure <NUM> may be disposed in a variety of ways, including but not limited to the embodiments shown below.

In some embodiments, referring to <FIG>, each group of the at least two groups of connection structures <NUM> includes two fixing portions <NUM>, and the two fixing portions <NUM> fix two ends <NUM> of the corresponding engaging beams <NUM>, respectively. Each fixing portion <NUM> of the two fixing portions <NUM> is arched with respect to the backplane substrate <NUM>, so as to form a gap <NUM> between each fixing portion <NUM> and the backplane substrate <NUM>. The end <NUM> of the engaging beam <NUM> fixed by each fixing portion <NUM> passes through the gap <NUM> of the fixing portion <NUM> and is bent before being buckled on the fixing portion <NUM>, so that the end <NUM> of the corresponding engaging beam <NUM> is prevented from falling out of the gap <NUM> of the fixing portion <NUM>, thereby realizing the fixation of the engaging beam <NUM>.

Exemplarily, referring to <FIG>, each of the fixing portions <NUM> includes: a first sub fixing portion <NUM> and a second sub fixing portion <NUM>. The first sub fixing portion <NUM> is arched with respect to the backplane substrate <NUM>, so as to form a first gap <NUM> between the first sub fixing portion <NUM> and the backplane substrate <NUM>; the second sub fixing portion <NUM> is arched with respect to the backplane substrate <NUM>, so as to form a second gap <NUM> between the second sub fixing portion <NUM> and the backplane substrate <NUM>. Wherein the first sub fixing portion <NUM> and the second sub fixing portion <NUM> are disposed apart from each other in the first direction M, and one end <NUM> of the engaging beam <NUM> fixed by the first sub fixing portion <NUM> and the second sub fixing portion <NUM> sequentially passes through the first gap <NUM> and the second gap <NUM> and is bent before being buckled on one or both of the first sub fixing portion <NUM> and the second sub fixing portion <NUM>, thereby realizing the fixation of the engaging beam <NUM>.

When the one end <NUM> of the engaging beam <NUM> is engaged with the first sub fixing portion <NUM> and the second sub fixing portion <NUM>, the number of position-limit points of the engaging beam <NUM> in the length extending direction is relatively large, so that the deformation of the engaging beam <NUM> can be reduced when engaged with the engaging hook <NUM>.

It is to be noted that, since the end <NUM> of the engaging beam <NUM> fixed by the first sub fixing portion <NUM> and the second sub fixing portion <NUM> sequentially passes through the first gap <NUM> and the second gap <NUM>, that is, when the engaging beam <NUM> is mounted, the end <NUM> passes through the first gap <NUM> and then passes through the second gap <NUM>. In other words, when the engaging beam <NUM> is mounted, the end <NUM> passes through the first sub fixing portion <NUM> and then passes through the second sub fixing portion <NUM>, thus the relative position relationship between the first sub fixing portion <NUM> and the second sub fixing portion <NUM> is as follows: the first sub fixing portion <NUM> is closer to the midpoint of the engaging beam <NUM> than the second sub fixing portion <NUM>.

Further, as shown in <FIG>, the dimension d of the first gap <NUM> in the perpendicular direction M' of the first direction M is larger than the dimension d<NUM> of the second gap <NUM> in the perpendicular direction M' of the first direction M, and/or the arching height h of the first sub fixing portion <NUM> relative to the backplane substrate <NUM> is larger than the arching height h<NUM> of the second sub fixing portion <NUM> relative to the backplane substrate <NUM>. That is, d > d<NUM>; or h > h<NUM>; or d > d<NUM> and h > h<NUM>.

The first direction M is a length extending direction of the body portion of the engaging beam <NUM> except for the two bent ends <NUM>. Exemplarily, as shown in <FIG>, the body portion of the engaging beam <NUM> includes a first beam section <NUM> and a second beam section <NUM> connected with each other. In some possible designs, the first direction M may be a transverse direction of the display surface of the display device, and the perpendicular direction M' of the first direction M may be a longitudinal direction of the display surface of the display device.

Since the end <NUM> of the engaging beam <NUM>, when being fixed, sequentially passes through the first sub fixing portion <NUM> and the second sub fixing portion <NUM>, and the dimension d of the first gap <NUM> is greater than the dimension d<NUM> of the second gap <NUM> in the perpendicular direction M' of the first direction M, and/or the arching height h of the first sub fixing portion <NUM> is greater than the arching height h<NUM> of the second sub fixing portion <NUM>, the first gap <NUM> with a larger dimension and/or a larger arching height can limit the engaging beam <NUM>, so as to prevent the deformation of the engaging beam from being too serious. The second gap <NUM> with a smaller dimension and/or a smaller arching height may facilitate to prevent the engaging beam <NUM> from moving in the perpendicular direction M' of the first direction M with respect to the first sub fixing portion <NUM>.

As another embodiment, in the perpendicular direction M' of the first direction M, the dimension d of the first gap <NUM> may also be equal to the dimension d1 of the second gap <NUM>, and the arching height h of the first sub fixing portion <NUM> may also be equal to the arching height h<NUM> of the second sub fixing portion <NUM>, which is not limited in this embodiment of the disclosure.

In the above embodiments, the fixing portion <NUM> includes two sub fixing portions, i.e., the first sub fixing portion <NUM> and the second sub fixing portion <NUM>. In some other embodiments, the fixing portion <NUM> may include only one sub fixing portion, e.g., only the first sub fixing portion <NUM>. When the fixing portion <NUM> may also include only the first sub fixing portion <NUM>, along the first direction M, the first gap <NUM> may be gradually increased in dimension in the perpendicular direction M' of the first direction M. That is, the first gap <NUM> may be flaring shaped in the first direction M. In other words, the dimension of the space <NUM> formed by the arching of the fixing portion <NUM> in the perpendicular direction M' of the first direction M is gradually increased, so that the gap <NUM> can not only limit the engaging beam <NUM> to reduce the deformation of the engaging beam <NUM>, but also prevent the end <NUM> of the engaging beam <NUM> from coming out of the fixing portion <NUM> better.

It is to be noted that the arching of fixing portion <NUM> with respect to the backplane substrate <NUM> may be formed by stamping, or the fixing portion <NUM> may be formed into an arched shape and then fixedly connected to the backplane substrate <NUM>, which may be selected according to a specific actual situation, and is not particularly limited herein.

In some embodiments, referring to <FIG>, at least one side of each fixing portion <NUM> of the plurality of fixing portions <NUM> included in the backplane <NUM> is provided with a through hole <NUM>, and the through hole <NUM> is disposed in the backplane substrate <NUM>. The dimension of the through hole <NUM> in the perpendicular direction M' of the first direction M is greater than or equal to the dimension of the fixing portion <NUM> adjacent thereto in the perpendicular direction M' of the first direction M.

Exemplarily, as shown in <FIG>, each fixing portion <NUM> includes a first sub fixing portion <NUM> and a second sub fixing portion <NUM>. One side of the first sub fixing portion <NUM> is provided with a through hole <NUM>, and a dimension d<NUM> of the through hole <NUM> in the direction M' is greater than or equal to a dimension d of the first sub fixing portion <NUM> in the direction M'; one side of the second sub fixing portion <NUM> is also provided with a through hole <NUM>, and the dimension d<NUM> of the through hole <NUM> is greater than or equal to the dimension d<NUM> of the second sub fixing portion <NUM> in the direction M'. In this way, when the arching of the first sub fixing portion <NUM> and the second sub fixing portion <NUM> with respect to the backplane substrate <NUM> is formed by stamping, the through holes <NUM> provided on the respective sides thereof can reduce deformation of the surrounding area of the stamping area during stamping.

Also, as shown in <FIG>, the through hole <NUM> can reduce the contact area between the engaging beam <NUM> and the backplane substrate <NUM>, so that the friction between the engaging beam <NUM> and the backplane substrate <NUM> can be reduced when the engaging beam <NUM> is deformed.

It is to be noted that the dimension of the fixing portion <NUM> in the perpendicular direction M' of the first direction M is the distance between two connection portions of the fixing portion <NUM> and the backplane substrate <NUM>. For example, as shown in <FIG>, the dimension d of the first sub fixing portion <NUM> of the fixing portion <NUM> in the direction M' is the distance between the connection positions of the two ends of the first sub fixing portion <NUM> and the backplane substrate <NUM>; the dimension d<NUM> of the second sub fixing portion <NUM> of the fixing portion <NUM> in the direction M' is the distance between the connection positions of the two ends of the second sub fixing portion <NUM> and the backplane substrate <NUM>.

The two fixing portions <NUM> included in each connection structure <NUM> for fixing each engaging beam <NUM> are not limited. In some embodiments, one fixing portion <NUM> of the two fixing portions <NUM> is disposed on the main surface W<NUM> of the backplane substrate <NUM> facing the rear housing substrate <NUM>, and the other fixing portion <NUM> of the two fixing portions <NUM> is disposed on the main surface W<NUM> of the backplane substrate <NUM> facing the rear housing substrate <NUM> or on the side surface W<NUM> of the backplane substrate <NUM>.

In some possible applications, as shown in <FIG>, one fixing portion <NUM> of the two fixing portions <NUM> is disposed on the main surface W<NUM> of the backplane substrate <NUM> facing the rear housing substrate <NUM>, and the other fixing portion <NUM> of the two fixing portions <NUM> is disposed on the side surface W<NUM> of the backplane substrate <NUM>. Based on this, as shown in <FIG>, the body portion of the engaging beam <NUM> except for the two ends <NUM> is bent into two portions: first beam section <NUM> and second beam section <NUM>; one end <NUM> connected to the first beam section <NUM> is inserted through the gap <NUM> of one of the fixing portions <NUM> on the main surface W<NUM>, and is engaged with the fixing portion <NUM>; the other end <NUM> connected to the second beam section <NUM> passes through the gap <NUM> of one of the fixing portions <NUM> on the side surface W<NUM> and is engaged with the fixing portion <NUM>. Thus, the engaging beam <NUM> can be mounted more simply and quickly without tightening screws.

Based on this, as shown in <FIG>, a notch <NUM> is provided at a corner where the side surface W<NUM> of the backplane substrate <NUM> is connected with the main surface W<NUM> of the backplane substrate <NUM> facing the rear housing substrate <NUM>, so that the engaging beam <NUM> is separated from the backplane substrate <NUM> at that corner, and thus, the engaging beam <NUM> can be prevented from friction against the backplane substrate <NUM> when the engaging beam <NUM> is deformed (for example, vibration of the display device during transportation) under an external force, and the abrasion of the backplane substrate <NUM> and the engaging beam <NUM> caused by the friction is reduced, and the adverse effect of the abrasion on the strength of the engaging beam <NUM> and the backplane substrate <NUM> is also reduced. In addition, the arrangement of the notch <NUM> can also prevent the chips generated by the friction between the engaging beam <NUM> and the corner of the backplane substrate <NUM> from affecting the normal operation of the display device.

In other possible applications, both fixing portions <NUM> may also be provided on the main surface W<NUM> of the backplane substrate <NUM> facing the rear housing substrate <NUM>. At this time, the body portion of the engaging beam <NUM> except the two ends <NUM> is not bent, and is located on the main surface W<NUM> of the backplane substrate <NUM> facing the rear housing substrate <NUM>.

The above two implementations of the arrangement position of the fixing portion <NUM> may be set according to the actual situation will not be particularly limited herein.

Further, as shown in <FIG>, the first sub fixing portion <NUM> and the second sub fixing portion <NUM> of each fixing portion <NUM> may be fixing strips. The shape formed by the arching of the first sub fixing portion <NUM> and the second sub fixing portion <NUM> is not limited, and may be curved (for example, as shown in <FIG>, the shape formed by the arching of the first sub fixing portion <NUM> and the second sub fixing portion <NUM> are both curved), triangular or the like and will not be particularly limited herein.

In some embodiments, referring to <FIG>, <FIG>, at least two through slots <NUM> are disposed in the backplane substrate <NUM> and are correspondingly disposed under the at least two engaging beams <NUM>, respectively, so that each engaging hook <NUM> of the at least two engaging hooks <NUM> is inserted into the corresponding through slot <NUM>, to be engaged with the corresponding engaging beam <NUM>. Through such a design, the engaging hook <NUM> can be conveniently engaged with the engaging beam <NUM>.

Exemplarily, the at least two through slots <NUM> are openings formed in the area of the backplane substrate <NUM> opposite to the engaging beam <NUM>, and when the engaging hooks <NUM> is engaged with the engaging beam <NUM>, the openings can accommodate the insertion of the engaging hooks <NUM>, so that the engaging hooks <NUM> is engaged with the engaging beam <NUM>, thereby realizing the relative fixation of the rear housing <NUM> and the backplane <NUM>.

What has been given above is an exemplary description of the connection structure <NUM>, and the embodiment of the disclosure does not limit the specific implementation structure of the connection structure <NUM>. As some possible designs, the connection structure <NUM> may also include a threaded hole disposed at the at least one end of the engaging beam <NUM> and a fixing table disposed on the backplane substrate <NUM>, such that at least one end of the engaging beam <NUM> is connected with the fixing table by a screw.

The engaging hooks <NUM> may be disposed in a variety of ways, including but not limited to the possible designs shown below.

In some embodiments, referring to <FIG>, each engaging hook <NUM> of the at least two engaging hooks <NUM> includes a bending portion <NUM>, one end of which is fixed to the rear housing substrate <NUM>, and the other end is a free end. The bending portions <NUM> are configured to be engaged with the corresponding engaging beams <NUM>.

In some possible designs, referring to <FIG>, the outer side of the bending portion <NUM> is provided with at least one reinforcing rib <NUM>. Wherein the outer side of the bending portion <NUM> is the side of the bending portion <NUM> opposite to the side for engaging the hooking beam <NUM>. In this way, the strength of the bending portion <NUM> of the engaging hook <NUM> can be improved, and when the bending portion <NUM> is engaged with the engaging beam <NUM>, the bending portion <NUM> can be firmly buckled on the engaging beam <NUM>; when subjected to an external force, for example, when the display device is subjected to vibration during transportation, the bending portion <NUM> is not easily disengaged from the engaging beam <NUM>, so that the engaging stability between the engaging hook <NUM> and the engaging beam <NUM> can be ensured, and looseness between the rear housing <NUM> of the display device and the backplane <NUM> can be further avoided.

In some possible designs, referring to <FIG>, each engaging hook <NUM> may further include a base <NUM> in addition to the bending portion <NUM> and the reinforcing rib <NUM>, the bending portion <NUM> may be fixed on the base <NUM>, that is, the bending portion <NUM> is fixed to the rear housing substrate <NUM> through the base <NUM>, so that the mounting stability of the engaging hook <NUM> on the rear housing substrate <NUM> may be improved.

The arrangement of the engaging beam <NUM> on the backplane substrate <NUM> and the arrangement of the engaging hook <NUM> on the rear housing substrate <NUM> include, but are not limited to, various ways shown below.

In some embodiments, referring to <FIG>, the backplane substrate <NUM> includes a first engaging area <NUM> and a second engaging area <NUM>, which are located on both sides of the bisector <NUM> of the backplane substrate <NUM> parallel to the second direction Y, respectively. Wherein the second direction Y is a direction parallel to the display surface determined by the display device.

At least one first engaging beam group <NUM> is disposed in the first engaging area <NUM>, and each first engaging beam group <NUM> of the at least one first engaging beam group includes a plurality of first engaging beams 311a, and the plurality of first engaging beams 311a are disposed apart from each other in the second direction Y.

At least one second engaging beam group <NUM> is disposed in the second engaging area <NUM>, and each second engaging beam group <NUM> of the at least one second engaging beam group <NUM> includes a plurality of second engaging beams 311b, and the plurality of second engaging beams 311b are disposed apart from each other in the second direction Y.

Accordingly, referring to <FIG>, a plurality of first engaging hooks 321a corresponding to the plurality of first engaging beams 311a one by one and a plurality of second engaging hooks 321b corresponding to the plurality of second engaging beams 311b one by one are disposed on the rear housing substrate <NUM>. Wherein the plurality of first engaging hooks 321a are disposed apart from each other in the second direction Y, and the plurality of second engaging hooks 321b are disposed apart from each other in the second direction Y, each first engaging hook 321a can be engaged with a corresponding first engaging beam 311a, and each second engaging hook 321b can be engaged with a corresponding second engaging beam 311b.

In this way, when the rear housing <NUM> is engaged with the backplane <NUM>, the backplane <NUM> and the rear housing <NUM> are uniformly stressed on both sides of the bisector <NUM> parallel to the second direction Y, and the number of engaging positions of the backplane <NUM> and the rear housing <NUM> in the second direction Y is large, so that the engaging between the rear housing <NUM> and the backplane <NUM> can be firmer.

Further, referring to <FIG>, the number of the first engaging beam groups <NUM> disposed in the first engaging area <NUM> is equal to the number of the second engaging beam groups <NUM> disposed in the second engaging area <NUM>. The number of engaging beams 311a included in each of the first engaging beam group <NUM> is equal to the number of second engaging beams 311b included in each of the second engaging beam groups <NUM>. The at least one first engaging beam group <NUM> and the at least one second engaging beam group <NUM> are symmetrically disposed on both sides of the bisector <NUM> of the backplane substrate <NUM>, which is parallel to the second direction Y.

Exemplarily, referring to <FIG>, a group of first engaging beam groups <NUM> is disposed in the first engaging area <NUM>, and the first engaging beam group <NUM> includes four first engaging beams 311a, and the four first engaging beams 311a are disposed apart from each other in the second direction Y.

A group of second engaging beam groups <NUM> is disposed in the second engaging area <NUM>, and the second engaging beam group <NUM> includes four second engaging beams 311b which are disposed apart from each other in the second direction Y.

Accordingly, referring to <FIG>, four first engaging hooks 321a and four second engaging hooks 321b are disposed on the rear housing substrate <NUM>. The four first engaging hooks 321a are disposed apart from each other in the second direction Y, and the four second engaging hooks 321b are disposed apart from each other in the second direction Y, and each first engaging hook 321a can be engaged with a corresponding second engaging beam 311a, and each second engaging hook 321b can be engaged with a corresponding second engaging beam 311b.

In this way, when the rear housing <NUM> is engaged with the backplane <NUM>, the number of the engaging positions of the backplane <NUM> and the rear housing <NUM> in the second direction Y is relatively large, and the backplane <NUM> and the rear housing <NUM> can be uniformly stressed in the second direction Y, so that the rear housing <NUM> and the backplane <NUM> can be more firmly fixed.

In some embodiments, as shown in <FIG>, the engaging beam <NUM> includes a first engaging beam 311a and a second engaging beam 311b. As shown in <FIG>, the hook <NUM> includes a first hook 321a and a second hook 321b. The hook mouths of the first hook 321a and the second hook 321b are opposite to each other, that is, the first hook 321a and the second hook 321b are used to be engaged with one side of the engaging beam.

During the engaging, as shown in <FIG>, the first hook 321a passes through the hollow portion <NUM>' of the first engaging beam 311a to hook the first engaging beam 311a, and the second hook 321b passes through the hollow portion <NUM>' of the second engaging beam 311b to hook the second engaging beam 311b, so as to achieve relative fixation of the rear housing <NUM> and the backplane <NUM>.

Further, referring to <FIG>, each first engaging beam group <NUM> includes an even number of first engaging beams 311a, and the even number of first engaging beams 311a are symmetrically disposed on both sides of the bisector <NUM> of the backplane substrate <NUM> parallel to the third direction X; each second engaging beam group <NUM> includes an even number of second engaging beams 311b, and the even number of second engaging beams 311b are symmetrically disposed on both sides of the bisector <NUM> of the backplane substrate <NUM> parallel to the third direction X.

The third direction X is a direction parallel to the display surface determined by the display device, and the second direction Y and the third direction X are perpendicular to each other. Exemplarily, the second direction Y is the horizontal direction of the display device, and the third direction X is the vertical direction of the display device; or, the second direction Y is the vertical direction of the display device, and the third direction X is the horizontal direction of the display device. It can be understood that, the second direction Y and the third direction X are perpendicular to each other and are both parallel to the display surface determined by the display device.

Exemplarily, referring to <FIG>, a group of first engaging beam groups <NUM> is disposed in the first engaging area <NUM>. The first engaging beam group <NUM> includes four first engaging beams 311a. The four first engaging beams 311a in the first engaging beam group <NUM> are symmetrically disposed in pairs on both sides of the bisector <NUM> of the backing plate substrate <NUM> parallel to the third direction X.

A group of second engaging beam groups <NUM> is disposed in the second engaging area <NUM>, and the second engaging beam group <NUM> includes four second engaging beams 311b. The four second engaging beams 311b in the second engaging beam group <NUM> are symmetrically disposed in pairs on both sides of the bisector <NUM> of the backplane substrate <NUM> parallel to the third direction X.

Correspondingly, referring to <FIG>, the rear housing substrate <NUM> is provided with four first hooks 321a and four second hooks 321b. Among them, the four first hooks 321a are symmetrically disposed in pairs on both sides of the bisector <NUM> of the rear housing substrate <NUM> parallel to the third direction X, and the four second hooks 321b are symmetrically disposed in pairs on both sides of the bisector <NUM> of the rear housing substrate <NUM> parallel to the third direction X, and each of the first hooks 321a may be engaged with a corresponding one of the second engaging beams 311a, and each of the second hooks 321b may be engaged with a corresponding one of the second engaging beam 311b.

In this way, when the rear housing <NUM> is engaged with the backplane <NUM>, the stress points are symmetrical with respect to the backplane <NUM> and bisector of the rear housing <NUM> parallel to the third direction X, thereby facilitating the backplane <NUM> and the rear housing <NUM> to be more uniformly stressed in the second direction Y. Moreover, since the eight engaging hooks <NUM> are engaged with the eight engaging beams <NUM> in a one-to-one correspondence manner, there are a relatively large number of the engaging contact positions between the rear housing <NUM> and the backplane <NUM>, so that the rear housing <NUM> and the backplane <NUM> can be more firmly after being engaged.

In some embodiments, referring to <FIG>, the backplane substrate <NUM> also includes a third engaging area <NUM> located on one of both sides of the backplane substrate <NUM> parallel to the bisector <NUM> of the third direction X.

At least one third engaging beam group <NUM> is disposed in the third engaging area <NUM>, and each third engaging beam group <NUM> of the at least one third engaging beam group <NUM> includes a plurality of third engaging beams 311c that are disposed apart from each other in the third direction X.

Accordingly, referring to <FIG>, a plurality of third engaging hooks 321c corresponding to the plurality of third engaging beams 311c one by one are provided on the rear housing substrate <NUM>. The plurality of third engaging hooks 321c are disposed apart from each other in the third direction X, and each third engaging hook 321c may be engaged with a corresponding one of the third engaging beams 311c.

In this way, the number of the third engaging beams 311c on the side of the bisector <NUM> of the backplane substrate <NUM> parallel to the third direction X can be increased, and the number of the third engaging hooks 321c on the side of the bisector <NUM> of the rear housing substrate <NUM> parallel to the third direction X can be increased, so that the number of the engaging contact positions of the rear housing <NUM> and the backplane <NUM> can be increased, and the firmness of the rear housing <NUM> and the backplane <NUM> after being engaged are improved. Meanwhile, the plurality of third engaging beams 311c are disposed apart from each other in the third direction X, and the plurality of third hooks 321c are disposed apart from each other in the third direction X, thereby ensuring the portion of the backplane substrate <NUM> located on the side of the bisector <NUM> of the backplane substrate <NUM> parallel to the third direction X and the portion of the backplane substrate <NUM> located on the side of the bisector <NUM> of the backplane substrate <NUM> parallel to the third direction X are more uniformly stressed in the third direction X.

Further, referring to <FIG>, each third engaging beam group <NUM> includes an even number of third engaging beams 311c, and the even number of third engaging beams 311c are symmetrically disposed on both sides of the bisector <NUM> of the backplane substrate <NUM>, which is parallel to the second direction Y.

Exemplarily, referring to <FIG>, a group of third engaging beam groups <NUM> is disposed in the third engaging area <NUM>. The third engaging beam group <NUM> includes four third engaging beams 311c. The four third engaging beams 311c in the third engaging beam group <NUM> are disposed symmetrically in pairs on both sides of the bisector <NUM> of the backplane substrate <NUM> parallel to the second direction Y.

Accordingly, referring to <FIG>, four third engaging hooks 321c are provided on the rear housing substrate <NUM>. The four third engaging hooks 321c are symmetrically disposed in pairs on both sides of the bisector <NUM> of the rear housing substrate <NUM> parallel to the second direction Y, and each third engaging hook 321c may be engaged with a corresponding third engaging beam 311c.

In this way, when the rear housing <NUM> is engaged with the backplane <NUM>, the stress points are symmetrical with respect to the backplane <NUM> and the rear housing <NUM> parallel to the second direction Y, so that the backplane <NUM> and the rear housing <NUM> are stressed more uniformly in the third direction X, and the rear housing <NUM> and the backplane <NUM> can be engaged more firmly.

The disposed position of the third engaging beam group <NUM> is not limited, for example, as shown in <FIG>, the third engaging beam group <NUM> may be located on one side of the bisector <NUM> of the backplane substrate <NUM> parallel to the third direction X. Correspondingly, as shown in <FIG>, the plurality of third hooks 321c are located on one side of the rear housing substrate <NUM> parallel to the bisector <NUM> of the third direction X. Thus, the rear housing <NUM> and the backplane <NUM> can be engaged more firmly. Meanwhile, the number of the engaging beams <NUM> on the backplane substrate <NUM> and the number of the engaging hooks <NUM> on the rear housing substrate <NUM> are not too large, so that the engaging structure <NUM> of the rear housing substrate <NUM> and the backplane substrate <NUM> is prevented from being too complicated to affect the assembly between them. In addition, the third engaging beam group <NUM> is located on one side of the bisector <NUM> of the backplane substrate <NUM> parallel to the third direction X, so that the first engaging structure <NUM> and the second engaging structure <NUM> can be prevented from affecting the arrangement of other components on the backplane <NUM>, such as circuits and electronic components, when the rear housing <NUM> is engaged with the backplane <NUM>.

In addition, exemplarily, the third engaging beam groups <NUM> can also be distributed on both sides of the bisector <NUM> of the backplane substrate <NUM> parallel to the third direction X, that is, on both sides of the bisector <NUM> of the backplane substrate <NUM> parallel to the third direction X. At this time, correspondingly, the plurality of third engaging hooks 321c are also symmetrically distributed on both sides of the bisector <NUM> of the rear housing substrate <NUM> parallel to the third direction X.

Exemplarily, each third engaging beam 311c of the third engaging beam group <NUM> is integrally formed with the backplane substrate <NUM> (as shown in <FIG>); or, each third engaging beam 311c of the third engaging beam group <NUM> is connected with the backplane substrate <NUM> through the connection structure <NUM> shown in <FIG>.

For example, the third engaging hook 321c and the rear housing substrate <NUM> may be integrally formed (as shown in <FIG>, for example), or may be designed separately. When the third engaging hooks 321c are integrally formed with the rear housing substrate <NUM>, the number of parts on the rear housing <NUM> can be reduced, thereby simplifying the structure for the rear housing <NUM> and reducing the assembly time of the rear housing <NUM>.

In some embodiments, as shown in <FIG>, there also may be provided with a through slot <NUM>, for inserting the third engaging hook 321c, between each third engaging beam 311c and the backplane substrate <NUM>. Thus, when the third engaging hook 321c is engaged with the third engaging beam 311c, the third engaging hook 321c can be easily inserted between the third engaging hook 311c and the backplane substrate <NUM> through the deformation of the third engaging hook 321c or the third engaging beam <NUM>.

It is to be noted that the first engaging hook 321a, the second engaging hook 321b, and the third engaging hook 321c may all be elastic engaging hooks. When the rear housing <NUM> is engaged with the backplane <NUM>, the first engaging hook 321a may be inserted into the through slot <NUM> through its own elastic deformation to realize engaging with the first engaging beam 311a, the second engaging hook 321b may be inserted into the through slot <NUM> through its own elastic deformation to realize engaging with the second engaging beam 311b, and the third engaging hook 321c may be inserted into the through slot <NUM> through its own elastic deformation to realize engaging with the third engaging beam 311c. In addition, the first engaging hook <NUM>, the second engaging hook 321b and the third engaging hook 321c may also be non-elastic engaging hooks. When the rear housing <NUM> is engaged with the backplane <NUM>, the first engaging hook <NUM>, the second engaging hook 321b and the third engaging hook 321c may be inserted into the through slot <NUM> through elastic deformation of the rear housing <NUM> (e.g., the engaging beam <NUM>) to be engaged with the corresponding first engaging beam 311a, the corresponding second engaging beam 311b and the corresponding third engaging beam 311c, respectively.

In some embodiments, referring to <FIG>, <FIG>, a boss is disposed on the backplane substrate <NUM>, and the at least two engaging beams <NUM> are disposed on the boss. This may improve the strength of the backplane substrate <NUM>, and thus can reduce the deformation of the backplane substrate <NUM> when the engaging beam <NUM> is engaged with the engaging hook <NUM>.

Exemplarily, as shown in <FIG>, two bosses <NUM> are provided on the backplane substrate <NUM>, and the two bosses <NUM> may be provided on both sides of the circuit board arrangement area <NUM> on the backplane substrate <NUM> in the first direction. For example, two first bosses <NUM> are respectively disposed at the first and second engaging areas <NUM> and132, the first engaging beam group <NUM> is disposed on the boss <NUM> of the first engaging area <NUM>, and the second engaging beam group <NUM> is disposed on the boss <NUM> of the second engaging area <NUM>.

Exemplarily, as shown in <FIG>, the backplane substrate <NUM> is provided with three bosses <NUM>, wherein two bosses <NUM> are respectively disposed in the first and second engaging areas <NUM> and <NUM>, and the third boss <NUM> is disposed in the third engaging area <NUM>. The first engaging beam group <NUM> is disposed on the boss <NUM> of the first engaging area <NUM>, the second engaging beam group <NUM> is disposed on the boss <NUM> of the second engaging area <NUM>, and the third engaging beam group <NUM> is disposed on the boss <NUM> of the third engaging area <NUM>. This can further improve the strength of the backplane substrate <NUM>, so that the deformation of the backplane substrate <NUM> can be reduced when the first engaging beam 311a of the first engaging beam group <NUM> is engaged with the first engaging hook 321a, the second engaging beam 311b of the second engaging beam group <NUM> is engaged with the second engaging hook 321b, and the third engaging beam 311c of the third engaging beam group <NUM> is engaged with the third engaging hook 321c of the third engaging beam group <NUM>. Also, in some possible designs, as shown in <FIG>, the boss <NUM> may be disposed on one side of the circuit pad area <NUM> on the backplane substrate <NUM> parallel to the bisector <NUM> of the second direction Y. For example, the boss <NUM> is disposed in the third engaging area <NUM>. This can avoid the third beam group <NUM> from affecting the arrangement of other components on the backplane <NUM>, such as circuits and electronic components, when the rear housing <NUM> is engaged with the backplane <NUM>.

It is to be noted that both the number of the engaging beams <NUM> and the number of the engaging hooks <NUM> may be one, and the hook mouth of the engaging hook <NUM> may be oriented perpendicular to the rear housing <NUM> and directed toward the backplane <NUM>. During engaging, both sides of the hook mouth of the engaging hook <NUM> are engaged with the engaging beams <NUM>, so as to fix the rear housing <NUM> to the backplane <NUM>.

The engaging beam <NUM> may extend in the second direction Y or the third direction X. Specifically, it may be matched with the structure of the engaging hook <NUM>, which is not limited herein.

In addition, the arrangement of the first and second engaging structures <NUM> and <NUM> is not limited. For example, in other embodiments, the first engaging structure <NUM> and the second engaging structure <NUM> may be as follows. The second engaging structure <NUM> includes an engaging protrusion disposed around a circumference edge of the backplane <NUM>, and the first engaging structure includes an engaging groove disposed on an inner side of a side surface of the rear housing <NUM>. The engaging groove is disposed around a circumference of the rear housing <NUM>, and engaged with the engaging protrusion, so that the rear housing <NUM> and the backplane <NUM> are relatively fixed.

Referring to <FIG>, some embodiments of the disclosure also provide a display device <NUM> including: a display screen <NUM>, a backlight module <NUM> and a rear housing <NUM>. The backlight module <NUM> is disposed on the rear surface of the display screen <NUM> (i.e. the surface of the display screen <NUM> opposite to the display surface), and the backlight module <NUM> includes an optical film material <NUM>' and a backplane <NUM>. The backplane <NUM> is located on the side of the optical film material <NUM>' away from the display screen <NUM>. The rear housing <NUM> is located on the side of the backplane <NUM> away from the optical film material <NUM>', and the backplane <NUM> and the rear housing <NUM> are relatively fixed by a mounting structure, and the mounting structure between the backplane <NUM> and the rear housing <NUM> is the mounting structure for the rear housing of the display device described in the above embodiments.

Because the mounting structure included in the display device provided by some embodiments of the disclosure is the same as the mounting structure for the rear housing of the display device described in the above embodiments, when the rear housing <NUM> is assembled with the backplane <NUM>, the engaging between the rear housing <NUM> and the backplane <NUM> can be achieved by applying a force directly to the backplane <NUM> or the rear housing <NUM>, so as to complete the assembly between the rear housing <NUM> and the backplane <NUM>. This procedure is simple and quick, does not require tightening screws one by one, so that a large amount of time can be saved, which is beneficial to assembly efficiency between the rear housing <NUM> and the backplane <NUM> of the display device.

The display device <NUM> may be any product or component having display function such as a liquid crystal panel, electronic paper, a cellphone, a tablet computer, a television, a display, a notebook computer, a digital picture frame and a navigator.

In the description of this specification, specific features, structures, materials or characteristics may be combined in any suitable manner in any one or more of embodiments or examples.
