DETAILED DESCRIPTION

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be specifically described below in conjunction with the drawings and the embodiments of the present disclosure.

In view of the technical problems in the related art of inconvenient assembly and disassembly, increased material cost and labor cost since a board and a backplane of a display device are fixed by screw fixation, a display device is provided by the present disclosure, such that the board and the backplane may be conveniently assembled and disassembled, and the labor cost and the material cost may be reduced, so as to improve production efficiency.

As shown inFIG. 1toFIG. 5, the display device provided by some embodiments of the present disclosure includes a backplane100, a board200, a first fastener arranged on the backplane, and a second fastener arranged on the board. The first fastener is in snap-fit connection with the second fastener. In an embodiment of the present disclosure, the first fastener is in detachable snap-fit connection with the second fastener. The first fastener includes a plurality of slots arranged on the backplane100; the second fastener includes a plurality of hooks provided on the board200; the hook is snapped into the slot to fix the backplane100to the board200by snap-fit.

In the above solution, the slot is arranged on the backplane100, and the hook is arranged on the board200. The board200may be assembled with the backplane100by merely snapping the hook into the slot; and the board200may be disassembled from the backplane100by merely detaching the hook from the slot. Compared with connecting the board200and the backplane100by screw fixation in the related art, the snap-fit connection of the board200and the backplane100not only provides a simple structure and enables a quick assembly and disassembly of the board200and the backplane100, so as to reduce the labor cost and greatly improve the production efficiency, but also eliminates the need for screws, which can reduce a screw material cost, and improve product competitiveness.

It should be noted that, in the above solution, the board200may be a motherboard200of the display device or other various types of boards200. The display device provided by some embodiments of the present disclosure may be various types of display devices such as a mobile phone or a tablet computer.

In the display device provided by the present disclosure, there may be a variety of manners for connecting the board200with the backplane100by snap-fit. In order to describe the display device provided by some embodiments of the present disclosure in more detail, an optional snap-fit connection structure for the board200and the backplane100is provided below.

As shown inFIG. 1andFIG. 3, in an optional embodiment of the present disclosure, the backplane100includes a mounting surface110for mounting the board200; a convex plate120is arranged on the mounting surface110, a cavity is provided inside the convex plate120; the convex plate120includes a top plate121and a side surface122surrounding the top plate121peripherally; the side surface122is provided with an opening1220leading to the cavity, and the opening1220is formed as the slot. In other words, the top plate121is substantially parallel to the mounting surface110and is spaced from the mounting surface110; the side surface122is located between the top plate121and the mounting surface110, and is connected to an edge of the top plate121and the mounting surface110respectively; and the side surface122surrounds the cavity.

According to the above solution, a surface on the backplane100for assembling the board200is the mounting surface110of the backplane100; the assembling surface110may be a planar surface of the backplane100; the protruding convex plate120is arranged on the mounting surface110; and the convex plate120is hollow inside; the opening1220is formed on the side surface122of the convex plate120; the opening1220can be used as the slot, to cooperate with the hook on the board200. Thus, by arranging the hollow convex plate120on the mounting surface110of the backplane100and providing the opening1220on the convex plate120to form the slot, the hook on the board200can be snapped into the opening1220to achieve a snap-fit connection. In addition, one of edges of the opening1220is located on a side proximate to the top plate121of the convex plate120(hereinafter referred to as a first edge), and the other edge which is opposite to the first edge is located on a side proximate to the mounting surface110(hereinafter referred to as a second edge). When the hook is snapped into the opening1220, the second edge of the opening1220cooperates with the first edge, or the second edge cooperates with the top plate121of the convex plate120, to limit the position of the hook in a first direction perpendicular to the mounting surface110(hereinafter referred to as upper position limit and lower position limit).

Of course, it can be understood that, in practice, other structures may be used to provide the slot on the backplane100. For example, the opening is directly formed on the mounting surface110of the backplane100, and the opening is used as the slot. It is simpler in structure, compared with the above-mentioned manner that the opening is formed on the side surface of the convex plate. However, the opening directly formed on the planar surface of the backplane can only implement the upper position limit of the hook, but not the lower position limit. Alternatively, a concave cavity formed by depressing the mounting surface may be provided on the backplane; a side wall of the concave cavity is provided with an opening to form the slot. However, compared with the above-mentioned manner of providing the opening on the side surface of the convex plate, if the opening is formed on the side wall of the concave cavity, the hook will protrude from the opening on the side wall of the concave cavity, such that the hook is exposed out of the concave cavity, which looks ugly, and is susceptible to accidental touch, such that the hook is detached from the opening. While in the foregoing optional embodiment, the hook can extend through the opening on the side surface of the convex plate into the cavity of the convex plate, thus the hook is concealed and is not susceptible to accidental touch.

In addition, it should be noted that the quantity and the specific distribution positions of the convex plates120provided on the backplane100can be reasonably configured according to actual needs, which is not limited herein.

In addition, in the optional embodiment of the present disclosure, the convex plate120may be a stamped convex plate formed by stamping and provided integrally with the backplane100. According to the above solution, the backplane is generally a metal backplane100, and the convex plate120can be formed by a stamping forming process, and the convex plate120and the backplane100are of an integral structure, so that the manufacturing process is simple.

Of course, it can be understood that, in practice, a separate convex plate120may also be arranged on the backplane100; or in case that the backplane100is a plastic backplane, the convex plate120may also be formed integrally with the backplane100by injection molding or the like.

In addition, in the optional embodiment of the present disclosure, as shown inFIG. 1andFIG. 3, a folded edge123is arranged at the second edge of the opening1220. The folded edge123is integrally connected with the side surface122and is bent into the cavity, to cooperate with the top plate121to form a position limit space, so as to implement the upper position limit and the lower position limit of the hook in a first direction perpendicular to the mounting surface110.

According to the above solution, the folded edge123is arranged on the second edge of the opening1220, and the folded edge123is bent toward the interior of the convex plate120with respect to the side surface122of the convex plate120, as a result, the position limit space is formed between the top plate121of the convex plate120and the folded edge123. When the hook on the board200is snapped into the opening1220, the hook abuts against both the folded edge123and the top plate121, so as to implement the upper position limit and the lower position limit of the hook on the board200in the first direction.

It should be noted that, in the above solution, a folded edge123is arranged on the second edge of the opening1220to perform the upper position limit and the lower position limit of the hook. In practice, a folded edge123may also be arranged at other edges of the opening1220to limit the position of the hook in other directions.

In addition, in the above solution, optionally, the folded edge123at the second edge of the opening1220is a stamped folded edge123formed by a stamping and bending process. Of course, it can be understood that the specific structure and the specific forming process of the folded edge123are not limited. For example, the folded edge123may be formed integrally with the backplane100by injection molding or the like, or the folded edge123may be connected to the second edge of the opening1220by soldering or the like.

In the above solution, by arranging the folded edge123at the second edge of the convex plate120, and using the folded edge123to cooperate with the top plate121of the convex plate120, the upper position limit and the lower position limit of the hook on the board200in the first direction perpendicular to the mounting surface110of the backplane100can be achieved. To make the connection between the backplane100and the board200stable, it is also necessary to limit the position of the board200in a direction parallel to the mounting surface110of the backplane100(hereinafter referred to as a left position limit and a right position limit). Thus, in the optional embodiment of the present disclosure, in order to achieve the left position limit and right position limit of the board200relative to the backplane100, a parallel position limit structure configured for limiting the position of the board200in the direction parallel to the mounting surface110is also arranged on the convex plate120.

Optionally, the parallel position limit structure is implemented as follows: as shown inFIG. 1toFIG. 5, a protruding limiting block130is arranged on the top plate121; a limiting hole210cooperating with the limiting block130is arranged on the board200, and the limiting hole210is located on one side of the hook; the limiting block130is placed in the limiting hole210, to limit a position of the board200in a direction parallel to the mounting surface110.

According to the above solution, by providing the limiting block130on the top plate121of the convex plate120, and providing the limiting hole210on the board200, the left position limit and the right position limit of the board200in the direction parallel to the mounting surface110are achieved by using the cooperation between the limiting block130and the limiting hole210. The position limit structure is simple. It should be noted that the parallel position limit structure is not limited thereto, and can also be implemented in other manners. For example, alternatively, the limiting hole is formed on the top plate121of the convex plate120, and the limiting block is arranged on the board200, and the limiting block is placed in the limiting hole, so as to implement the left position limit and the right position limit of the board200in the direction parallel to the mounting surface110.

In the optional embodiment of the present disclosure, as shown inFIG. 1toFIG. 5, the limiting hole210is an elongated hole extending in a second direction parallel to the mounting surface110, and the elongated hole includes a first end and a second end opposite to each other; the limiting block130includes a first limiting block131and a second limiting block132spaced apart in the second direction, the first limiting block131is located at the first end, and the second limiting block132is located at the second end.

According to the above solution, the limiting hole210is an elongated hole, a lengthwise direction of the elongated hole is the second direction, and the limiting block130on the convex plate120includes the first limiting block131and the second limiting block132spaced apart in the second direction. The first limiting block131can tightly engage with the elongated hole at the first end of the elongated hole; the second limiting block132can tightly engage with the elongated hole at the second end of the elongated hole. Thus, the left position limit and the right position limit of the board200in the second direction can be achieved.

It should be noted that, in practice, the limiting hole210may also include two through holes spaced apart in the second direction, and the position limit of the board200in the second direction can also be achieved through the two through holes.

It should also be noted that, in the above solution, the limiting hole210does not specifically refer to a through-hole structure penetrating the board200, instead, the limiting hole210may refer to a blind hole structure. For example, in case that the board200has a sufficient thickness, the blind hole structure may be formed on the board200to serve as the limiting hole according to the actual needs.

Compared with implementing the limiting hole210by using other structures, the limiting hole210in the form of the elongated hole has following advantages.

In a first aspect, the limiting hole210is an elongated hole, so that the forming process is simple.

In a second aspect, when assembling the board200and the backplane100, the assembly process can be performed by pushing the board200along a lengthwise direction of the elongated hole. The opening1220on the convex plate120is located on one side where the first end of the elongated hole is located. Thus, along an assembling direction F as shown inFIG. 1(the assembling direction F is the lengthwise direction of the elongated hole), firstly the second limiting block132at the second end of the elongated hole may be snapped into the elongated hole to position the board200, and then the board200is pushed along the assembling direction to snap the first limiting block131at the first end of the elongated hole into the elongated hole, so that the left position limit and the right position limit of the board200is achieved. At the same time, the hook on the board200is pressed into the opening1220on the convex plate120to achieve the snap-fit, thereby completing the assembly of the board200and the backplane100. It can be seen that, by designing the limiting hole210as the elongated hole, the assembly becomes more convenient. The provision of the limiting hole210and the limiting block130can not only implement the left position limit and the right position limit of the board200, but also can serve a pre-positioning purpose during assembly, thereby improving assembly efficiency.

Optionally, an inner edge of the first end of the elongated hole is curved, and an inner edge of the second end of the elongated hole is rectilinear; the first limiting block131has a curved surface that matches in shape with the inner edge of the first end of the elongated hole, and the second limiting block132has a flat surface that matches in shape with the inner edge of the second end of the elongated hole.

When the board200and the backplane100are assembled by using the above solution, as shown inFIG. 1,FIG. 4andFIG. 5, first, the board200is placed on the mounting surface110of the backplane100, and the elongated hole is aligned with the second limiting block132so that the second end of the elongated hole abuts against the flat surface of the second limiting block132to pre-position the board200; then, the board200is pushed along the assembling direction as shown inFIG. 1, during the process, the inner edge of the first end of the elongated hole and the curved outer peripheral surface of the first limiting block131may serve as a guiding mechanism, so that the first limiting block131is snapped into the elongated hole, and fits closely with the inner edge of the first end of the elongated hole, thereby limiting the position of the board200.

It can be seen that, the inner edge of the first end of the elongated hole is designed to be curved, and the inner edge of the second end is designed to be rectilinear. Correspondingly, the outer peripheral surface of the first limiting block131includes a curved surface that can closely fit with the inner edge of the first end of the elongated hole, and the outer peripheral surface of the second limiting block132includes a flat surface that can closely fit with the inner edge of the second end of the elongated hole, which can achieve a pre-positioning during assembly, and achieve the left position limit and the right position limit of the board200in a direction parallel to the mounting surface110. Moreover, since the curved inner edge of the first end of the elongated hole fits closely with the curved surface of the first limiting block131, the board200can also be limited in a third direction, that is, a front position limit and a back position limit may be achieved. The third direction is a direction perpendicular to both the first direction and the second direction.

It should also be noted that, in the above solution, for example, the inner edge of the first end of the elongated hole may be of a circular arc shape or other curved shape. Correspondingly, the curved surface on the first limiting block131may be of the circular arc surface or other curved shape. For example, the first limiting block131is a cylindrical block, and the second limiting block132is a cuboid block, therefore the forming process is simple. Of course, it can be understood that the specific shapes of the first limiting block131and the second limiting block132are not limited.

It should also be noted that the limiting block130described in the above solution is designed to be two blocks, namely the first limiting block131and the second limiting block132. In practice, the limiting block130may also be directly designed to be an elongated block structure, which is matched in shape with the elongated hole. Because the first limiting block131and the second limiting block132are different in shape, compared with the design of a single elongated block structure, the design of two separate limiting blocks130is easier to implement as far as the forming process is concerned.

The slot on the backplane100is described above exemplarily. Hereinafter, an optional structure of the hook on the board200will be described. In some embodiments of the present disclosure, as shown inFIG. 2,FIG. 3andFIG. 4, optionally, the hook includes an elastic sheet structure220, the elastic sheet structure220includes a first part221and a second part222, and the first part221is connected to the board200, the second part222is formed by bending and extending a side of the first part221that is away from the board200. The elastic sheet structure220can be elastically deformed when subjected to an external force, thus a bending angle between the first part221and the second part222may vary, such that the elastic sheet structure220is snapped into or detached from the opening1220.

According to the above solution, the structure of the hook on the board200is simple, and the hook is implemented by using the elastically deformable elastic sheet structure220. When the elastic sheet structure220and the slot on the backplane100are assembled, the elastic sheet structure220on the board200is pressed into the slot on the backplane100; in doing so, the elastic sheet structure220is elastically deformed. Specifically, the first part221and the second part222provided in a bent configuration are pressed by the slot, and the bending angle becomes smaller, so that the elastic sheet structure220can enter the slot successfully; upon entering the slot, the bending angle between the first part221and the second part222increases, so that the elastic sheet structure220is in snap-fit connection with the slot. When it is necessary to detach the board200from the backplane100, the elastic sheet structure220is elastically deformed by an external force, so that the elastic sheet structure220can be detached from the slot.

It should be understood that the specific structure of the hook is not limited to the above-mentioned elastic sheet structure220, but may be of other hook structures. The above specific structure is only exemplary, and does not limit the structure of the hook.

In the optional embodiment of the present disclosure, as shown inFIG. 2andFIG. 3, the elastic sheet structure220and the board200are of an integral structure, and the elastic sheet structure220is formed by depressing the board200toward the backplane100.

According to the above solution, the elastic sheet structure220may be formed integrally with the board200, and may be formed by stamping or injection molding. This structure is easier to implement in consideration of the process, and does not incur additional material cost. Of course, it can be understood that, in practice, the elastic sheet structure220may also be separately connected to the board200by other means, such as, bonding or soldering.

In addition, in the above solution, when the elastic sheet structure220is pressed into the opening1220of the convex plate120, a joint between the first part221and the second part222of the elastic sheet structure220may abut against the folded edge123of the side surface122of the convex plate120on the backplane100, and a side of the second part222that is away from the first part221may abut against the top plate121of the convex plate120, so that the upper position limit and the lower position limit of the elastic sheet structure220in the direction perpendicular to the mounting surface110of the backplane100may be achieved by using the folded edge123and the top plate121in conjunction.

In order to further ensure the reliability of the structure, as shown inFIG. 2,FIG. 3andFIG. 4, the elastic sheet structure220may further include a third part223, which is formed by bending and extending the side of the second part222that is away from the first part221, the joint between the first part221and the second part222abuts against the folded edge123, and the third part223abuts against the top plate121.

According to the above solution, through forming the third portion223by bending the side of the second part222that is away from the first part221so that the third part223abuts against the top plate121of the convex plate120, the third part223functions as a supporting plane, such that the elastic sheet structure220engages with the top plate121of the convex plate120more reliably.

Further, optionally, a through hole124leading to the cavity is provided on the top plate121at a position corresponding to the opening1220. Due to the through hole124provided on the top plate121of the convex plate120, when the board200is to be detached from the backplane100, an person can apply an external force to the elastic sheet structure220through the through hole124, so that the elastic sheet structure220is deformed and detached from the slot of the backplane100. In addition, in the above solution, the elastic sheet structure220is further provided with the third part223. Since the third part223has the supporting plane, it is also more beneficial to apply the external force to the third part223through the through hole124, to deform the elastic sheet structure220and detach it from the slot.

In addition, as shown inFIG. 1, in the optional embodiment of the present disclosure, the first limiting block131and the second limiting block132are spaced apart in the second direction, and the through hole124is arranged adjacent to the first limiting block131. In consideration of the component structure of the display device, a spatial layout of the convex plate120and the elastic sheet structure220should be as compact as possible. Therefore, optionally, the top plate121of the convex plate120is substantially triangular, as long as the top plate121have sufficient space to arrange the first limiting block131, the second limiting block132and the through hole124. Of course, it can be understood that, in practice, the top plate121may be of other shape, which is not limited herein.

In addition, as shown inFIG. 1, the opening1220on the side surface122of the convex plate120is not arranged on an extension of an imaginary line connecting the first limiting block131and the second limiting block132in the second direction, but is arranged on one side of the extension, so that the through hole124can be arranged on the top plate121. In practice, the opening1220on the side surface122of the convex plate120may also be arranged on the extension of the imaginary line connecting the first limiting block131and the second limiting block132in the second direction, so that an area of the top plate121of the convex plate120can be smaller, so as to reduce the space occupied by the top plate121of the convex plate120in the third direction (for example, the third direction can be perpendicular to both the second direction and the first direction). The elastic sheet structure220on the board200corresponds to the opening1220in position; the limiting hole210corresponds to the first limiting block131and the second limiting block132in position. Therefore, a description of the position arrangement of the elastic sheet structure220and the limiting hole on the board200is not repeated here.

The above embodiments are merely optional embodiments of the present disclosure. It should be noted that improvements and modifications may be made by those skilled in the art without departing from the principle of the present disclosure, and these improvements and modifications should also be deemed as falling within the scope of the present disclosure.
