[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] It should be noted that if the utility model involves directional indications (such as up, down, front, back, etc.), such directional indications are only used to explain the relative position relationship between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly; if the utility model involves descriptions of "first", "second", etc., such descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

[0022] Figures 1 to 3 It is a structural schematic diagram of the heat dissipation button of the utility model, wherein: Figure 1 The figure shows a three-dimensional structural diagram of the heat dissipation button of the utility model. Figure 2 The cross-sectional structure diagram of the heat dissipation button of the utility model is shown. Figure 3 The figure shows the exploded structure diagram of the heat dissipation button of the utility model. For the convenience of description, only the parts related to the utility model are shown in the figure.

[0023] Depend on Figure 1 , Figure 2 and Figure 3 It can be seen that the heat dissipation button includes a button body 10, and the side of the heat dissipation button corresponding to the inside of the electronic product is defined as the inner side, and the other side away from the electronic product is defined as the outer side. The outer side of the button body 10 is used for pressing, and also includes a circuit board 20 fixed on the inner side of the button body 10, an electronic device 30 arranged on the side of the circuit board 20 close to the outer side of the button body 10, and a heat dissipation structure 40 arranged at the corresponding circuit board 20. The heat dissipation structure 40 includes a heat collecting part bonded to the circuit board 20, a heat dissipation part spaced apart from the heat collecting part and extending outside the button body 10, and a deformation part connected between the heat collecting part and the heat dissipation part. When the button body 10 is pressed, the deformation part will follow and deform.

[0024] During installation, the heat dissipation button is installed on the housing of the electronic device, and the circuit board 20 and the electronic device 30 are correspondingly arranged inside the electronic device. Since the heat collecting part of the heat dissipation structure 40 is attached to the circuit board 20, and the heat dissipation part is attached to the housing or heat sink of the electronic device, the heat generated by the circuit board 20 and the electronic device 30 can be dissipated to the housing or heat sink of the electronic device through the heat dissipation structure 40 for heat dissipation, thereby enhancing the heat dissipation effect; when the heat dissipation button is pressed, since there is a deformation part connected between the heat collecting part and the heat dissipation part, the circuit board 20, the electronic device 30 and the heat collecting part will move synchronously with the button body 10, driving the deformation part to deform, so that the heat collecting part moves relative to the heat dissipation part, and the heat dissipation structure 40 will not affect the pressing of the heat dissipation button; the heat dissipation button of the utility model solves the problem of poor heat dissipation effect of existing buttons, and can improve user experience.

[0025] In the utility model, the heat collecting part is set as a heat collecting plate 41, which can increase the contact area between the heat dissipation structure 40 and the circuit board 20, which is convenient for heat collection; the heat dissipation part is set as a heat dissipation plate 42, which can increase the contact area between the heat dissipation structure 40 and the housing or heat sink of the electronic device, which is convenient for heat dissipation; the deformation part is set as an elastic connecting plate 43, which can enhance the heat transfer performance between the heat collecting part and the heat dissipation part.

[0026] Specifically, the heat collecting part, the deformation part and the heat dissipating part are connected as a whole, which is convenient for processing.

[0027] Typically, the heat dissipation structure 40 is a plate structure made of a graphite sheet, a graphene sheet, an elastic heat pipe or an elastic metal plate, which utilizes its own elasticity to form the deformation of the deformation part and is not easy to break.

[0028] In some other embodiments, the heat dissipation structure 40 may also be configured as a split structure, which is connected together by bonding or welding with a thermally conductive adhesive.

[0029] In order to further prevent the heat dissipation structure 40 from affecting the pressing of the heat dissipation button, the heat dissipation plate 42 is arranged away from the heat collecting plate 41, and the elastic connecting plate 43 connected between the heat collecting plate 41 and the heat dissipation plate 42 is arranged obliquely, and an angle α is provided between the elastic connecting plate 43 and the heat collecting plate 41, and an angle β is provided between the elastic connecting plate 43 and the heat dissipation plate 42, and the angles α and β are obtuse angles. Space can be reserved for the deformation of the deformation part to avoid interference with the pressing of the heat dissipation button.

[0030] In the utility model, in order to facilitate the installation of the circuit board 20 and the electronic device 30, at least two groups of hook structures are provided on the inner side of the button body 10 and are arranged at intervals along the extension direction of the circuit board 20. Each group of hook structures includes a first hook body 11 and a second hook body 12 which are arranged at intervals on opposite sides of the circuit board 20. During installation, the electronic device 30 is first soldered to the circuit board 20, and then the circuit board 20 is clamped between the first hook body 11 and the second hook body 12 of the at least two groups of hook structures.

[0031] Specifically, the hook structure is provided with two groups, and of course three or more groups can be provided as required.

[0032] In the present invention, the button body 10 includes a pressing plate 13 and a skirt 14 arranged around the circumferential side of the pressing plate 13 . The outer side of the pressing plate 13 forms a pressing portion, and the inner side of the pressing plate 13 forms a mounting portion.

[0033] Specifically, the pressing plate 13 and the skirt 14 are connected as an integrated structure and are made of materials such as plastic and metal.

[0034] In some other embodiments, the pressing plate 13 and the skirt 14 may also be configured as a split structure, and fixedly connected by bonding, welding, or the like.

[0035] Usually, the skirt 14 is an elastic member made of elastic material, which is easy to press and rebound, and does not need to be provided with elastic reset members such as springs. When the pressing plate 13 and the skirt 14 are connected as an integral structure, the pressing plate 13 and the skirt 14 can be combined into one by injection molding; when the pressing plate 13 and the skirt 14 are separate structures, they can be fixedly connected by bonding or hot-melt welding.

[0036] The above descriptions are only some embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
