[0045] A heat conducting pad 6 is arranged in the heat conducting hole 50 and attached to the back of the heat spreading sheet 4.

[0046] A bracket 7 is attached to the back of the compressed foam 5 and fixedly connected with the front shell 1, and the back of the heat conducting pad 6 is attached to the surface of the bracket 7.

[0047] A rear shell 9 is fixedly connected with the front shell 1.

[0048] In this embodiment, the screen frame adhesive 2 is first fixedly attached to the back of the front shell 1 during assembly, the screen frame adhesive 2 has a frame structure and a narrow width, and the screen frame adhesive 2 can be double-sided adhesive. Then the heat spreading sheet 4 is fixed to the back of the screen assembly 3, the heat spreading sheet 4 can be fixed to the screen assembly 3 by adhesion, and the front end of the screen assembly 3 is attached to the back of the screen frame adhesive 2. In one embodiment of the heat spreading sheet 4, the heat spreading sheet 4 can be a graphite sheet. Then the compressed foam 5 can be fixed to the front end of the bracket 7, and the compressed foam 5 can be fixedly attached to the bracket 7, the heat conducting pad 6 is placed in the heat conducting hole 50 of the compressed foam 5, the heat conducting pad 6 can be fixedly attached to the bracket 7, and the thickness of the heat conducting pad 6 is close to the thickness of the compressed foam 5, so that the heat conducting pad 6 can be attached to the surface of the heat spreading sheet 4. Then the bracket 7 is fixed to the front shell 1, and the two can be locked together by screws, and finally the rear shell 9 is fixed to the front shell 1, and the assembly of the entire screen is completed (as shown in Figure 2 ).

[0049] The utility model discloses one aspect, after the screen frame glue 2 of relatively narrow screen frame is used for sticking and fixing the screen assembly 3 in the front shell 1, can play the role of fixing screen assembly 3, can also play the role of waterproof dustproof and anti-static, and when clicking the screen, even if the screen is thin and the rigidity is small, the screen frame glue 2 can also pull the screen and prevent deformation, improve the feeling when clicking, and because screen frame glue 2 is used for sticking and fixing screen assembly 3, so only need to stick screen frame glue 2 on the front shell 1 when installing, then screen assembly 3 can be stuck on screen frame glue 2, and the installation process is relatively simple and convenient, and when disassembling, because screen frame glue 2 is an independent component, so the disassembly process is also relatively easy.

[0050] On the other hand, after setting the compression foam 5 on the back of the screen assembly 3, it can prevent deformation when pressing the screen, and can improve the pressing feeling, and the compression foam 5 can absorb part of the impact force when the screen assembly 3 is impacted, avoiding damage.

[0051] In addition, the back of the screen assembly 3 is provided with a heating sheet 4, which can quickly and uniformly disperse the heat generated by the screen assembly 3, and then transmit it to the support 7 through the heat-conducting pad 6. The support 7 serves as both an installation support structure and a heat dissipation structure, improving the heat dissipation performance of the entire device.

[0052] On the basis of the above embodiment, the screen fixing structure in the present embodiment further comprises a screen adapter 8, which is fixed to the back of the support 7. The support 7 is provided with a threading hole, and the control line of the screen assembly 3 passes through the threading hole and is connected to the screen adapter 8. The screen adapter 8 is used for signal conversion.

[0053] During assembly, after the support 7 is fixedly connected to the front shell 1, the control line of the screen assembly 3 is extended to the back of the support 7 through the threading hole, and then the screen adapter 8 is fixed to the back of the support 7. The control line is connected to the screen adapter 8, and signal conversion is performed through the screen adapter 8. The screen adapter 8 and the support 7 can be fixedly connected through multiple screws.

[0054] In one embodiment, as shown in Figure 4 The back of the front shell 1 is provided with a mounting groove, which is in the form of a ring. The screen frame glue 2 is embedded in the mounting groove, and a part of the screen frame glue 2 protrudes from the mounting groove and is bonded to the screen assembly 3.

[0055] Specifically, in the present embodiment, the position of the screen frame glue 2 can be positioned through the mounting groove, which facilitates the bonding and fixing of the screen frame glue 2 during assembly. Secondly, after part of the screen frame glue 2 is accommodated in the mounting groove, the gap between the front shell 1 and the screen assembly 3 caused by the thickness of the screen frame glue 2 is reduced, avoiding excessive gap and improving dustproof ability and aesthetics.

[0056] Since the screen frame glue 2 will be deformed under pressure when bonding and fixing the screen assembly 3, the width of the mounting groove in the embodiment is greater than the width of the screen frame glue 2, so as to provide a certain deformation space for the screen frame glue 2.

[0057] Further, the periphery of the heat-conducting pad 6 closely matches the periphery of the heat-conducting hole 50, so as to reasonably utilize the space and improve the heat-conducting performance. In order to improve the heat dissipation effect, the support 7 is made of metal material with good heat dissipation performance. Since the support 7 has a large area and is made of metal material with good heat dissipation performance, the heat dissipation performance of the entire module can be greatly improved.

[0058] As shown in Figure 1 In order to further increase the connection stability and structural rigidity, the rear shell 9 is snap-connected with the front shell 1 in the embodiment, the upper and lower ends of the support 7 are provided with fixing portions 70 corresponding to the side walls of the front shell 1, and the side walls of the front shell 1, the fixing portions 70 and the side walls of the rear shell 9 are locked by a plurality of fixing screws.

[0059] Specifically, in the embodiment, first, the rear shell 9 is snap-connected with the front shell 1, and then the rear shell 9 and the front shell 1 are positioned before being locked by the fixing screws. The fixing screws can be connected on the four side walls of the front shell 1 and the rear shell 9, and the upper and lower ends of the support 7. After the front shell 1, the support 7 and the rear shell 9 are locked together by the fixing screws, the rigidity of the support 7 is strengthened, and the strength of the entire module is improved.

[0060] According to another aspect of the present application, an electronic device is provided, which comprises the above screen fixing structure.

[0061] The above only describes the preferred embodiments of the present application and is not used to limit the present application.
