[0042] The following is combined with Figure 1 to Figure 7 The utility model is further described in detail, but it is not intended to limit the utility model.

[0045] A clip 14 is also provided on the main body 11. The clip 14 is arranged corresponding to the clip groove 111 and the fixing groove 112. The clip 111 includes a buckle 141 and a first protrusion 142. The buckle 141 and the first protrusion 142 are integrally arranged. The buckle 141 is clipped with the clip groove 111. A limiting groove 143 is provided between the first protrusion 142 and the fixing groove 112.

[0046] The utility model comprises a main body 11, a buffer part 12 is arranged on the side of the main body 11, the buffer part 12 is in close contact with the main body 11, a support part 13 is also arranged on the main body 11, the support part 13 has an upward support surface 131, the support part 13 is integrally arranged with the main body 11, and the support part 13 protrudes from the surface of the main body 11, the main body 11 is provided with a snap-fitting groove 111 and a fixing groove 112, the snap-fitting groove 111 and the fixing groove 112 are arranged back to back and communicate with each other at the top, and a convex part 1111 with an inclined surface is arranged in the snap-fitting groove 111.

[0047] Specifically, an elastic support structure 1 is provided in the keyboard 2, and the elastic support structure 1 replaces the fixed middle plate in the existing keyboard 2. The elastic support structure 1 in the present application is easy to replace, and only the damaged elastic support structure 1 needs to be replaced individually, and the buffer 12 abuts against the upper cover 21 and the bottom plate 24. When in use, the PCB board 23 is subjected to downward pressure, and the PCB board 23 transmits the pressure to the main body 11. The main body 11 moves downward under the pressure, and the main body 11 squeezes the elastic support structure 1 when moving. The elastic support structure 1 absorbs the pressure and the elastic support structure 1 is deformed. After the squeezing ends, the main body 11 completely releases the pressure through the elastic support structure 1, and the elastic support structure 1 resets to drive the main body 11 and the PCB board 23 to reset and return to the initial position. The buffer 12 in the present application is softly connected with the upper cover 21 and the bottom plate 24, and will not generate noise when subjected to force, and will not damage the user's use environment.

[0048] In some embodiments, the main body 11 further includes a connecting portion 113 protruding from the main body 11 , and a connecting groove 121 is provided inside the buffer 12 , and the buffer 12 is connected to the connecting portion 113 via the connecting groove 121 .

[0049] Specifically, a connecting portion 113 is provided on the main body 11 for installing the buffer 12. The buffer 12 is further fixed by the connecting portion 113 to prevent the buffer 12 from moving. It also facilitates installation. The buffer 12 only needs to be put on the connecting portion 113 to complete the installation.

[0050] In some embodiments, the width and height of the connection portion 113 are smaller than the width and height of the connection groove 121 , and the length of the connection portion 113 is consistent with the length of the connection groove 121 .

[0051] Specifically, the size of the connecting portion 113 is smaller than the size of the connecting groove 121, which is convenient for installation. The width and height of the connecting groove 121 are larger than the width and height of the connecting portion 113. During installation, the connecting groove 121 can more easily cover the connecting portion 113, and the length of the connecting groove 121 is consistent with the length of the connecting portion 113, so that the buffer 12 can contact with the main body 11, and the buffer effect is better. At the same time, the strength of the elasticity can be adjusted according to actual conditions. For example, when a harder pressing feel is required, the buffer 12 Move toward the side away from the main body 11, and reduce the contact area between the connection part 113 and the buffer 12. The reduction in the contact area reduces the buffering force of the buffer 12, and the remaining force acts on the main body 11. Since the structural strength of the main body 11 is relatively high, the pressing feel is relatively hard. If a softer pressing feel is desired, the buffer 12 is brought into contact with the main body 11 as much as possible. At this time, the contact area between the connection part 113 and the buffer 12 is the largest. When pressed, all the force is absorbed by the buffer 12, thereby increasing the buffering elasticity.

[0052] In some embodiments, the connection portion 113 and the buffer member 12 are provided correspondingly, and at least two connection portions 113 and two buffer members 12 are provided.

[0053] Specifically, in the present embodiment, at least two connecting parts 113 and corresponding buffer members 12 are provided. If only one is provided, the buffer member 12 cannot absorb the pressing force well when pressed, thereby failing to achieve the buffering effect. At the same time, if more than two are provided, the elastic support structure 1 will take up a large amount of space. If there is a large amount of spare space, more than two may be provided. However, in the present application, two connecting parts 113 and two buffer members 12 are the most preferred, which can absorb the pressing force without taking up a large amount of space.

[0054] In some embodiments, the two connection portions 113 are symmetrically disposed on two sides of the main body 11 .

[0055] Specifically, the connection part 113 and the corresponding buffer member 12 are arranged on both sides of the main body 11. When installed, the buffer member 12 contacts the upper cover 21 and the bottom plate 24, so that the main body 11 is suspended in the air. When pressed, the energy absorption effect of the buffer member 12 is maximized.

[0056] In some embodiments, the buffer 12 is an elastic rubber structure.

[0057] Specifically, the reason why the buffer 12 adopts a rubber structure in the present embodiment is that the rubber structure is made of polymer material, has good elasticity, and can effectively reduce the vibration and friction of the keyboard 2 cover 21 and the bottom plate 24; while reducing friction, it can also reduce the penetration of sound. Since reducing friction can essentially reduce the noise during pressing, and then reducing the penetration of sound, the buffer 12 in the present application has a better effect of sound insulation and noise reduction. At the same time, the rubber structure is relatively stable, and has better adaptability and durability, which can increase the service life of the elastic support structure 1.

[0058] In some embodiments, the upper and lower surfaces of the buffer 12 have a plurality of force dissipating structures 122 . The force dissipating structures 122 are in a wave shape, an arc shape, a triangle shape, or a rectangle shape. A force dissipating groove 123 is provided between two force dissipating structures 122 .

[0059] Specifically, when the upper cover 21 and / or the bottom plate 24 are subjected to force, they are squeezed inward, and the buffer member 12 abutting against the upper cover 21 and the bottom plate 24 is deformed, and the force dissipation structure 122 can absorb energy. After absorbing energy, the force dissipation structure 122 is deformed, and the deformed force dissipation structure 122 diffuses toward the force dissipation groove 123, further improving the buffering capacity.

[0060] In this embodiment, if Figure 4 As shown, the force dissipating structure 122 and the force dissipating groove 123 are both arc-shaped.

[0061] In some embodiments, the connection groove 121 is symmetrically shaped with being narrow in the middle and wide on both sides.

[0062] Specifically, as shown in the figure, in this embodiment, the middle part of the connecting groove 121 is squeezed and matched with the connecting part 113 to achieve a fixed connection between the buffer 12 and the connecting part 113. When the buffer 12 absorbs energy, the buffer 12 is deformed, and the deformed part diffuses to the areas on both sides of the connecting groove 121, further releasing the pressure after absorbing energy.

[0063] Embodiment 2

[0064] The difference between the embodiment and the first embodiment is that the clamping portion and the main body 11 are integrally provided in the embodiment.

[0065] Specifically, Figure 7 As shown, the integral arrangement of the clamping portion and the main body can increase the structural strength of the elastic support structure and extend its practical life. During installation, the elastic support structure is first assembled with the PCB board, and then the elastic support structure is placed between the upper cover and the bottom plate.

[0066] The other structures are the same as those in the first embodiment and will not be described in detail in this embodiment.

[0069] Specifically, the above-mentioned elastic support structure 1 is provided in the keyboard 2, and the upper cover 21 and the bottom plate 24 are interference fit through the elastic support structure 1. The space between the upper cover 21 and the bottom plate 24 is filled by the elastic support structure 1, so that the connection between the upper cover 21 and the bottom plate 24 is more stable. Several elastic support structures 1 are arranged along the circumference of the upper cover 21, and the PCB board 23 is supported by the elastic support structure 1 so that the middle part of the PCB board 23 is suspended in the air. Then, the elasticity during use is further improved by the elastic support structure 1, and the hand feel is better.

[0070] In some embodiments, a second bump 213 is disposed at an edge of the PCB board 23 , and the second bump 213 is disposed in the limiting groove 143 .

[0071] Specifically, Figure 2 and Figure 3 As shown, the buckle 141 is engaged with the engaging groove 111. During installation, the second protrusion 213 is placed in the limiting groove 143. The PCB board 23 is positioned and limited by the second protrusion 213 to prevent the PCB board 23 from being displaced during installation and to fix the PCB board 23.

[0072] It should be noted that a mounting portion 25 is provided on both the upper cover 21 and the bottom plate 24 . The mounting portion 25 corresponds to the elastic support structure 1 , and the mounting portion 25 presses the buffer 12 in both upper and lower directions, and the elastic support structure 1 is further fixed by the mounting portion 25 .
