[0028] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0029] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0031] An embodiment of this utility model provides an elastic rubber pad, such as Figure 1 and Figure 2As shown, the device includes a base 110 and an abutment plate 120. The abutment plate 120 is located on top of the base 110 and connected to the base 110. A central hole 101 is provided on the bottom surface of the base 110, penetrating both the base 110 and the abutment plate 120. The central hole 101 allows a mounting base to be inserted for mounting the entire elastic pad. The base 110 is provided with a positioning structure 111 for positioning the base 110. The positioning structure 111 restricts the rotation and / or lateral movement of the base 110, thus keeping the entire elastic pad in the mounting position and preventing displacement that would prevent it from providing elastic force to the circuit board. The abutment plate 120 may be disc-shaped and has an abutment portion 121 for abutting the circuit board. The abutment portion 121 abuts against the surface of the circuit board and can provide elastic restoring force to the circuit board by resisting the deformation of the abutment plate 120, thereby allowing the display on the circuit board to be tightly attached to the panel. The abutment plate 120 is provided with multiple openings 122. The presence of the openings 122 is equivalent to reducing the local structural strength of the abutment plate 120, making the abutment plate 120 more easily deformable, and the elasticity of the entire elastic pad is better. It is easier to adaptively adjust the distance between the display on the circuit board and the panel, thereby making the display on the circuit board and the panel fit tightly.

[0032] In some embodiments, the abutment plate 120 is frustum-shaped, and the inner diameter of the abutment plate 120 gradually increases in the upward direction. This forms a frustum-shaped cavity on the inner side of the abutment plate 120. The presence of the cavity provides greater room for deformation of the abutment plate 120, and the abutment plate 120 has better elasticity. When the circuit board is subjected to pressure, the abutment plate 120 is easier to bend and press against the circuit board.

[0033] In some embodiments, the abutment portion 121 is an abutment ring disposed on the edge of the abutment plate 120 and protruding upward. The contact area between the abutment ring and the circuit board is larger. When the circuit board is pressed, the pressure on the abutment ring is relatively uniform. The entire abutment plate 120 can deform uniformly relative to the central hole 101 to provide a relatively balanced elastic force. The display can be relatively flat and tightly attached to the panel.

[0034] In some embodiments, the base 110 is cylindrical, and the outer diameter of the abutment plate 120 is larger than the outer diameter of the base 110. The base 110 is relatively smaller and more compact, which reduces the material used in the base 110 and makes it easier to install the base 110 stably on the mounting base. The abutment plate 120 is larger, and the elastic force can be mainly provided by the deformation of the abutment plate 120.

[0035] In some embodiments, the openings 122 are evenly distributed relative to the axis of the central hole 101, and the deformation characteristics of the abutment plate 120 at various points can be kept relatively balanced relative to the axis of the central hole 101 to provide relatively balanced elastic force.

[0036] In some embodiments, the positioning structure 111 is a positioning groove provided on the side wall of the base 110, and the positioning groove communicates with the center hole 101. For this purpose, a limiting plate can be provided on the mounting base, and the limiting plate is inserted into the positioning groove to position the base 110.

[0037] Furthermore, the positioning groove penetrates the side wall of the base 110 and extends to the abutment plate 120. In this embodiment, the positioning groove is longer, allowing the limiting plate to pass through the positioning groove and be inserted into the positioning groove on the abutment plate 120 to improve the positioning effect.

[0038] In some embodiments, the base 110, the abutment plate 120, and the abutment portion 121 may be integrally formed to facilitate the manufacturing of the entire elastic pad and to enhance the connection strength between them.

[0039] In some embodiments, the entire elastic pad can be made of an elastically deformable insulating material, such as silicone, rubber, or plastic, which provides elasticity while preventing safety issues such as short circuits with the circuit board.

[0040] An embodiment of this utility model provides a circuit board mounting structure, such as... Figure 3-6 As shown, it includes a base plate 200, a circuit board 300, a connector 400, and an elastic pad from any of the above embodiments. For a detailed description of the elastic pad, please refer to the above embodiments, which will not be repeated here.

[0041] A mounting base 210 is provided on the top surface of the base plate 200. The circuit board 300 is located above the mounting base 210. The mounting base 210 is inserted into the center hole of the base 110 to fix the base 110. The abutment part 121 abuts against the bottom surface of the circuit board 300, and the deformation of the abutment plate 120 can provide an elastic restoring force to the circuit board 300. The mounting base 210 is provided with a limiting structure 211, which cooperates with the positioning structure of the base 110 to limit the rotation of the base 110 relative to the mounting base 210. The entire elastic pad can be kept in the installation position to prevent displacement that would prevent the elastic force from being provided to the circuit board.

[0042] The circuit board 300 has a through hole through which a connector 400 passes and is fixedly connected to the mounting base 210. The connector 400 includes a connector head 410 for preventing the circuit board 300 from detaching from the connector 400. The circuit board 300 can move vertically, but due to the restriction of the connector head 410, the circuit board 300 will not detach from the connector 400. The elastic force provided by the elastic pad allows the circuit board 300 to move upwards towards the panel.

[0043] In some embodiments, the positioning structure is a positioning groove provided on the side wall of the base 110, the positioning groove is connected to the center hole, and the limiting structure 211 is a limiting plate provided on the side wall of the mounting base 210, the limiting plate is inserted into the positioning groove, thereby positioning the base 110 and limiting the rotation and / or lateral movement of the base 110.

[0044] Furthermore, the positioning groove penetrates the side wall of the base 110 and extends to the abutment plate 120. In this embodiment, the positioning groove is longer, allowing the limiting plate to pass through the positioning groove and be inserted into the positioning groove on the abutment plate 120 to improve the positioning effect.

[0045] In some embodiments, the connector 400 is a screw, and the connector head is the head of the screw. The outer diameter of the screw head is larger than the inner diameter of the through hole, preventing the screw head from passing through the through hole, thereby preventing the circuit board 300 from detaching from the connector 400.

[0046] In some embodiments, the surface of the circuit board 300 may be fixed with devices such as a display 310 and buttons.

[0047] In some embodiments, the base plate 200 may be the base plate of the display box, and the entire circuit board 300 may be located inside the display box.
