In some embodiments of the present disclosure, referring to <FIG>, each of the first frame plate <NUM>, the first frame wall <NUM>, the back case wall <NUM>, the second frame plate <NUM>, and the second frame wall <NUM> may have a ring shape. It should be noted that the back case <NUM> and the first frame wall <NUM> are not illustrated in <FIG>. In this case, the first frame wall <NUM> may be located in an outer edge region of an annulus surface of the first frame plate <NUM>, the second frame wall <NUM> may be located in an outer edge region of an annulus surface of the second frame plate <NUM>, and the back case wall <NUM> may be located in an edge region of the back case plate <NUM>. In some examples of the present disclosure, an outer surface of the first frame wall <NUM> may not be flush with an outer surface of the first frame plate <NUM>. In some embodiments of the present disclosure, the first frame wall <NUM> and the back case wall <NUM> may be nested one inside the other, and the first frame wall <NUM>, the back case wall <NUM>, and the second frame plate <NUM> may each surround a region surrounded by the first frame plate <NUM>, and the second frame wall <NUM> may surround the first frame plate <NUM>, the first frame wall <NUM>, the back case plate <NUM>, and the back case wall <NUM>.

In some examples of the present disclosure, each of the first frame plate <NUM>, the first frame wall <NUM>, the back case wall <NUM>, the second frame plate <NUM>, and the second frame wall <NUM> may also be composed of a plurality of independent components, and the plurality of components may be configured in the form of a ring, which is not limited in the embodiments of the present disclosure.

In some examples of the present disclosure, at least two of the first frame <NUM>, the back case <NUM>, and the second frame <NUM> may be engaged with each other, for example, the engagement may be achieved by means of an engagement protrusion and an engagement recess (this way is taken as an example in <FIG>). In some examples of the present disclosure, the engagement may also be performed by other ways, for example, by means of cooperation between an engagement protrusion and an engagement protrusion, which is not limited in the embodiments of the present disclosure.

<FIG> illustrates an example in which the first frame <NUM>, the back case <NUM> and the second frame <NUM> are engaged with one another, and shows a case where the back case wall <NUM> is located between the first frame wall <NUM> and the second frame wall <NUM>, that is, the back case wall <NUM> surrounds the first frame wall <NUM>, and both the first frame <NUM> and the second frame <NUM> are engaged with the back case <NUM>. In some examples of the present disclosure, the first frame <NUM>, the back case <NUM>, and the second frame <NUM> may be engaged in a relationship different from that shown in <FIG>. For example, there may also be an embodiment where the first frame wall is located between the back case wall and the second frame wall, that is, the first frame wall may surround the back case wall, and both the back case and the second frame may be engaged with the first frame, which is not limited in the embodiments of the present disclosure.

In some examples of the present disclosure, only two of the first frame <NUM>, the back case <NUM>, and the second frame <NUM> may also be engaged, and the remaining one may be connected to the engaged two of the first frame <NUM>, the back case <NUM>, and the second frame <NUM> by other means (such as bonding or screw connection). For example, the first frame <NUM> may be engaged with the back case <NUM>, and the second frame <NUM> may be connected to the back case <NUM> by other means; or the second frame <NUM> may be engaged with the back case <NUM>, and the first frame <NUM> may be connected to the back case <NUM> in other ways, which is not limited in the embodiments of the present disclosure.

According to the embodiments of the present disclosure, the first frame <NUM>, the back case <NUM>, and the second frame <NUM> are fixed by engaging them with one another instead of usage of screws for fixation such that no fixation structure such as a screw is exposed on outer surface of the frame and thus the frame is simpler and more beautiful. Further, the engaged fixation can allow the frame to be easier to be assembled and disassembled. In addition, the second frame wall <NUM> surrounds the first frame plate <NUM>, the first frame wall <NUM>, the back case plate <NUM>, and the back case wall <NUM>, so that the second frame <NUM> can protect the first frame <NUM> and the back case <NUM> and can also play a decorative role for the frame to improve the aesthetics of the frame.

A space between the first frame <NUM> and the back case <NUM> may be used to accommodate a display panel <NUM>, and the first frame <NUM> and the back case <NUM> can fix a position of the display panel <NUM> and protect the display panel <NUM>. In some embodiments of the present disclosure, the display panel may include a display screen, a device or line connected to the display screen, and other devices (such as light sensors and audio devices) used in conjunction with the display screen. The display screen may be any structure with a display function such as a liquid crystal display screen, an organic light-emitting diode display screen, or electronic paper.

In some examples of the present disclosure, material for manufacturing the frame can have a good flexibility. In some embodiments of the present disclosure, the material for manufacturing the frame may be plastic, such as acrylonitrile butadiene styrene (ABS, for abbreviation), or may be a mixture of the ABS plastic and polymeric methyl methacrylate (PMMA, for abbreviation), or a mixture of polycarbonate (PC, for abbreviation) and PMMA, etc..

In summary, at least two of the first frame, the back case, and the second frame in the frame provided by the embodiments of the present disclosure are engaged with each other, so that part or all of the frame may be assembled or disassembly without a tool, and thus the assembly or disassembly process of the frame is relatively simple.

Hereinafter, description and explanation will be made only by taking a case where the first frame wall <NUM> is surrounded by the back case wall <NUM>, and a case where both the first frame <NUM> and the second frame <NUM> are engaged with the back case <NUM> as examples.

In some examples of the present disclosure, one of the first frame <NUM> and the back case <NUM> may have a first engagement protrusion, the other may have a first engagement recess, and the first engagement protrusion is engaged in the first engagement recess, in order to realize the engagement between the first frame <NUM> and the back case <NUM>. One of the second frame <NUM> and the back case <NUM> may have a second engagement protrusion, and the other may have a second engagement recess, and the second engagement protrusion is engaged in the second engagement recess to realize the engagement between the second frame <NUM> and the back case <NUM>.

For example, as shown in <FIG>, the back case <NUM> may have a first engagement protrusion T1, the first frame <NUM> may have a first engagement recess C1, and the first engagement protrusion T1 is engaged in the first engagement recess C1; the back case <NUM> may have a second engagement recess C2, the second frame <NUM> may have a second engagement protrusion T2, and the second engagement protrusion T2 is engaged in the second engagement recess C2.

The number of each of the first engagement protrusion T1, the first engagement recess C1, the second engagement protrusion T2 and the second engagement recess C2 may be more than one. The plurality of first engagement protrusions T1 are in one-to-one correspondence with the plurality of first engagement recesses C1, and each first engagement protrusion T1 is engaged in one corresponding first engagement recess C1; the plurality of second engagement protrusions T2 are in one-to-one correspondence with the plurality of second engagement recesses C2, and each second engagement protrusion T2 is engaged in one corresponding second engagement recess C2. The plurality of first engagement protrusions T1, the plurality of first engagement recesses C1, the plurality of second engagement protrusions T2, or the plurality of second engagement recesses C2 can be evenly distributed on a surface on which they are located.

In other examples of the present disclosure, the first engagement protrusion T1 is located on the first frame <NUM>, the first engagement recess C1 is located on the back case <NUM>, the second engagement protrusion T2 is located on the back case <NUM>, and the second engagement recess C2 is located on the second frame <NUM>, which are not limited in the embodiments of the present disclosure.

In the situation shown in <FIG>, an orthographic projection of the first engagement protrusion T1 on the back case plate <NUM> may be opposite to an orthographic projection of the second engagement recess C2 on the back case plate <NUM>. That is, if the back case <NUM> is divided into a plurality of parts according to the length of the first engagement protrusion T1 or the second engagement recess C2, the part where the first engagement protrusion T1 is located may further have the second engagement recess C2.

In other examples of the present disclosure, the orthographic projection of the first engagement protrusion T1 on the back case plate <NUM> is offset from the orthographic projection of the second engagement recess C2 on the back case plate <NUM>. <FIG> shows the case, which is a sectional view of the first engagement protrusion T1 and one corresponding first engagement recess C1 (such as a portion W1 in <FIG>) in the frame; <FIG> shows the case, which is a sectional view of the second engagement protrusion T2 and one corresponding second engagement recess C2 (such as a portion W2 in <FIG>) in the frame. Compared with the situation shown in <FIG>, in this case, the strength of the back case wall <NUM> can be better.

In some examples of the present disclosure, the first engagement recess C1 and the second engagement recess C2 may be through holes penetrating through the first frame wall <NUM> and the back case wall <NUM>, respectively, or may be recesses, which do not penetrate through the first frame wall <NUM> and the back case wall <NUM>, respectively. If the engagement recesses are the through hole respectively penetrating through the first frame wall <NUM> and the back case wall <NUM>, there is increased space for adjustment of each engagement protrusion in the engagement recess, thereby avoiding a situation where the engagement protrusion cannot be completely engaged into the corresponding engagement recess due to a relatively great manufacturing error of the engagement protrusion; if the engagement recesses are the recesses that do not penetrate through the first frame wall <NUM> and the back case wall <NUM>, respectively, the strength of the first frame wall <NUM> and the back case wall <NUM> having the engagement recesses can be increased. In the embodiments of the present disclosure, <FIG> illustrates an example in which the first engagement recess C1 and the second engagement recess C2 are both recesses that do not penetrate through the first frame wall <NUM> and the back case wall <NUM>, and <FIG> illustrate examples in which the first engagement recess C1 is a through hole penetrating the first frame wall <NUM>, and the second engagement recess C2 is a recess that does not penetrate the back case wall <NUM>.

In some examples of the present disclosure, with continued reference to <FIG>, <FIG>, the first engagement protrusion T1 may have a first surface A1 facing towards the back case plate <NUM> and a second surface A2 facing away from the back case plate <NUM>. The first surface A1 may be parallel to and in contact with a wall surface of the first engagement recess C1 facing away from a first reference surface, and the first reference surface is the surface of the first frame plate <NUM> facing away from the back case plate <NUM>. In some examples of the present disclosure, the second surface A2 of the first engagement protrusion T1 facing away from the back case plate <NUM> and the wall surface of the first engagement recess C1 facing towards the first reference surface make an angle with each other and are spaced apart from each other.

In some embodiments of the present disclosure, the first surface A1 may be perpendicular to the back case wall <NUM>, and the second surface A2 may extend toward the surface of the first engagement protrusion T1 facing away from the back case wall <NUM> and be inclined towards the back case plate <NUM>. The first surface A1 may be in contact with the wall surface of the first engagement recess C1 facing away from the first reference surface. In this way, the first engagement recess C1 can prevent the first engagement protrusion T1 from moving in the direction towards the back case plate <NUM>, thereby limiting a relative position between the first frame <NUM> and the back case <NUM>. Moreover, the first engagement protrusion T1 may have a small volume such that the first engagement recess C1 may have a space for adjustment of the first engagement protrusion T1 and the first engagement protrusion T1 is subject to small hindrance from a structure that is in contact with the first engagement protrusion T1 when assembling the frame and thus the first engagement protrusion T1 can be easily engaged in the first engagement recess C1, reducing the difficulty of assembling the frame. Moreover, due to the small volume of the first engagement protrusion T1, the first engagement protrusion T1 can also be easily disengaged from the first engagement recess C1 when the frame is disassembled, thereby further reducing the difficulty of disassembling the frame.

In some examples of the present disclosure, the second engagement protrusion T2 may have a third surface A3 facing towards the second frame plate <NUM> and a fourth surface A4 facing away from the second frame plate <NUM>. In some embodiments of the present disclosure, the surface of the back case plate <NUM> facing away from the first frame plate <NUM> may be the second reference surface, and the third surface A3 may be parallel to and in contact with the wall surface of the second engagement recess C2 facing away from the second reference surface. In some examples of the present disclosure, the fourth surface A4 may make an angle with and be spaced from the wall surface of the second engagement recess C2 facing towards the second reference surface. For example, the third surface A3 may be perpendicular to the second frame wall <NUM>, and the fourth surface A4 may extend towards the surface of the second engagement protrusion T2 facing away from the second frame wall <NUM> and be inclined towards the second frame plate <NUM>; and the third surface A3 may be in contact with a wall surface of the second engagement recess C2 facing away from the second reference surface.

In some examples of the present disclosure, the first engagement recess C1 may be located on the first frame wall <NUM>, both the first engagement protrusion T1 and the second engagement recess C2 may be located on the back case wall <NUM>, and the second engagement protrusion T2 may be located on the housing wall <NUM>. In other examples of the present disclosure, the first engagement recess C1 may also be located on both the first frame wall <NUM> and the first frame plate <NUM>, and the second engagement recess C2 may also be located on both the back case wall <NUM> and the back case plate <NUM>, which are not limited in the embodiments of the present disclosure.

In the embodiments of the present disclosure, only an example is described in which the section of the first engagement recess C1 and the second engagement recess C2 is rectangular, and sizes of an opening and bottom surface of the engagement recess are the same, as shown in <FIG>, <FIG>. In some examples of the present disclosure, the section may also have a shape of a trapezoid, such as a right-angled trapezoid. In this case, an area of the opening of the engagement recess may be larger than an area of the bottom surface of the engagement recess, which is not limited in the embodiments of the present disclosure.

In some examples of the present disclosure, with continued reference to <FIG>, the back case <NUM> may further include: a position limit part X protruding from the edge region of the surface, facing towards the first frame plate <NUM>, of the back case plate <NUM>, the position limit part X may include a first position limit protrusion X1, and the first frame wall <NUM> may be located between the back case wall <NUM> and the first position limit protrusion X1. <FIG> shows a structure of a part of the back case including a position limit part. The first position limit protrusion X1 can cooperate with the first engagement protrusion and the first engagement recess to fix the relative position between the first frame and the back case, preventing movement of the first frame wall in the z direction and deformation of the first frame wall under the action of an external force.

With continued reference to <FIG>, the position limit part X may further include: a second position limit protrusion X2 connected to the first position limit protrusion X1. <FIG> shows a structure of a part of the first frame. As shown in <FIG>, an edge D of the first frame wall <NUM> facing away from the first frame plate <NUM> has a position limit recess C3 that is configured to match the second position limit protrusion X2. Referring to <FIG>, the second position limit protrusion X2 may be located in the position limit recess C3 to prevent the movement of the first frame wall in the y direction. In some examples of the present disclosure, edges of the position limit recess C3 may have a chamfer or a rounded corner, so that the second position limit protrusion X2 can easily engaged into the position limit recess C3.

In some examples of the present disclosure, the number of the position limit parts X in the back case <NUM> may be more than one, the plurality of position limit parts may be evenly distributed in the edge region of the back case plate <NUM>, and each position limit part may be located between two first engagement protrusions T1.

<FIG> is a schematic view showing a structure of a position limit part. In some examples of the present disclosure, referring to <FIG> and <FIG>, each position limit part may include a plurality of the first position limit protrusions X1 and a plurality of the second position limit protrusions X2 (<FIG> and <FIG> are example in which two first position limit protrusions X1 and two second position limit protrusions X2 are included) and in the embodiment, each first position limit protrusion X1 may be connected to one corresponding second position limit protrusion X2, and the plurality of first position limit protrusions X1 may be connected through a connecting structure L to increase strength of the position limit part. A recess C4 may be provided in the connection structure L between two first position limit protrusions X1 of a single position limit part to increase flexibility of the position limit part. The recess may have a U shape, a polygonal shape, or a circular shape, or the like, which is not limited in the embodiments of the present disclosure. The edge of the first position limit protrusion X1, facing towards the back case wall <NUM>, at an end of the first position limit protrusion X1 facing away from the back case plate <NUM> may have a chamfer or a rounded corner to reduce hindrance of the first frame wall by the position limit protrusion X1 when assembling the first frame and thus reduce the difficulty of assembling the frame.

In some examples of the present disclosure, with continued reference to <FIG>, the edge of the back case wall <NUM> facing away from the back case plate <NUM> may also have a notch K. The notch K may be disposed close to any one of the plurality of first engagement protrusions on the back case wall, for more convenient disassembly of the frame. When the frame is disassembled, the back case wall can be pulled outward through the gap K on the back case, so that the first engagement protrusion close to the gap K is disengaged from the first engagement recess where the engagement protrusion is received. In this case, a gap will be generated between the back case wall and the first frame wall such that other first engagement protrusions can also be gradually disengaged from the corresponding first engagement recesses by the gap thereby realizing the disengagement of the back case and the first frame.

In some examples of the present disclosure, with continued reference to <FIG>, <FIG>, the first frame wall <NUM> and the back case wall <NUM> may have the same height, so that the edge of the back case wall <NUM> facing away from the back case plate <NUM> may be in contact with the surface of the first frame plate <NUM> facing towards the back case plate <NUM>, and the edge of the first frame wall <NUM> facing away from the first frame plate <NUM> may be in contact with the surface of the back case plate <NUM> facing towards the first frame plate <NUM>. This design can be favor of fixation of positions of the first frame <NUM> and the back case <NUM> by the first engagement protrusion T1 and the first engagement recess C1 and avoid the first engagement protrusion T1, after being located in the first engagement recess C1, from continuously sliding out of the first engagement recess C1 in a direction away from the back case plate <NUM> under the action of external force, so that the first frame <NUM> and the back case <NUM> are more securely engaged.

In some examples of the present disclosure, with continued reference to <FIG>, <FIG>, the edge of the first frame wall <NUM>, facing away from the first frame plate <NUM> and facing towards the back case wall <NUM>, may have a chamfer or rounded corner. The edges of the back case wall <NUM> facing away from the back case plate <NUM> may have chamfers or rounded corners. Due to the rounded corners or chamfers, a thickness of the edge of the first frame wall <NUM> facing away from the first frame plate <NUM> is reduced, and a thickness of the edge of the back case wall <NUM> facing away from the back case plate <NUM> is also reduced. A structure contacting the chamfered or rounded corner can have reduced hindrance on the wall in which the chamfered or rounded corner is located during assembling of the frame, and thus the difficulty of assembling the frame can be further reduced. In some examples of the present disclosure, the edge of the second frame wall <NUM> facing away from the second frame plate <NUM> and facing towards the back case wall <NUM> may also have a chamfer or rounded corner, which is not limited in the embodiments of the present disclosure.

In some examples of the present disclosure, with continued reference to <FIG> and <FIG>, the surface of the first frame plate <NUM> facing towards the back case plate <NUM> may have a reinforcement structure for enhancing strength of the first frame plate <NUM> and thus in turn enhancing durability of the frame <NUM>. In some embodiments of the present disclosure, the reinforcement structure may be composed of at least one reinforcement bar G, the reinforcement bar G may have a ring shape, the reinforcement bar G may surround the region surrounded by the first frame plate <NUM>; and when the reinforcement structure includes a plurality of reinforcement bars G, the plurality of reinforcement bars G may be disposed as outer reinforcement bars G surrounding inner reinforcement bars G. <FIG> illustrate an example in which the reinforcement structure includes two reinforcement bars G and <FIG> illustrates an example in which the reinforcement structure includes only one reinforcement bar G. In some examples of the present disclosure, the reinforcement structure may also be composed of a plurality of reinforcement protrusions, the plurality of reinforcement protrusions may be arranged in a ring, and the plurality of reinforcement protrusions may also surround the region surrounded by the first frame plate <NUM>.

In some examples of the present disclosure, the surface of the back case plate <NUM> facing towards the first frame plate <NUM> may also be provided with a reinforcement structure, which may include a plurality of reinforcement bars arranged in an array, or may also include a plurality of reinforcement bars arranged in a grid. That is not limited in the embodiments of the present disclosure.

In some examples of the present disclosure, with continued reference to <FIG>, <FIG>, the frame <NUM> may further include: a third frame <NUM>. The third frame <NUM> may include a third frame plate <NUM> and a third frame wall <NUM>. The third frame plate <NUM> may be located on the side of the first frame plate <NUM> facing away from the back case plate <NUM>, and the third frame wall <NUM> may protrude from the surface of the third frame plate <NUM> facing towards the first frame plate <NUM>.

<FIG> is a schematic structural view of the third frame.
