[0036] Figure 1A schematic diagram of the overall structure of the button structure 100 according to an embodiment of the present invention is shown. Figure 2 for Figure 1 An exploded view of the button structure 100. Figure 3 for Figure 1 A schematic diagram of the button structure 100 from another perspective. Figure 4 for Figure 3 A schematic diagram of the cross-sectional structure along the AA direction. (See diagram below.) Figure 1 , 2 As shown in Figures 3 and 4, this utility model proposes a button structure 100 and an electronic device. The button structure 100 of this utility model includes a button 10, a fixing member 20, and an elastic member 30. The button 10 has a groove 12, and a connecting post 11 is disposed in the groove 12. The fixing member 20 is disposed in the groove 12 and has a through hole. The connecting post 11 passes through the through hole and extends to the side of the through hole away from the bottom surface of the groove 12. When the button 10 is configured to be pressed or rebounded, it can move relative to the fixing member 20 along the axial direction of the connecting post 11. The elastic member 30 is disposed in the groove 12 and is located on the side of the fixing member 20 away from the bottom surface of the groove 12. When the button 10 is configured to rebound, the two ends of the elastic member 30 along the axial direction of the connecting post 11 abut against the connecting post 11 and the fixing member 20, respectively.
[0037] By using the button structure 100 in this technical solution, the button 10 can be pressed or rebounded, thereby moving relative to the fixing member 20 along the axial direction of the connecting post 11. When the button 10 rebounds, the two ends of the elastic member 30 along the axial direction of the connecting post 11 can respectively abut against the fixing member 20 and the connecting post 11, so that the button 10 can be buffered when it rebounds, and the button 10 is abutted against the fixing member 20 through the connecting post 11 and the elastic member 30, preventing the button 10 from falling out.
[0038] Specifically, in this embodiment, the button 10 can be pressed by the operator, that is, the bottom surface of the groove 12 moves towards the fixing member 20. At this time, the elastic member 30 will not interact with the fixing member 20 and the connecting post 11. After being pressed, the button 10 can rebound, that is, the bottom surface of the groove 12 moves away from the fixing member 20. At this time, the connecting post 11 can press the elastic member 30 against the side of the fixing member 20 away from the bottom surface of the groove 12, thereby making the elastic member 30 buffer the rebound of the connecting post 11, and making the connecting post 11 of the button 10 locked onto the fixing member 20 by the elastic member 30.
[0039] Specifically, in this embodiment, one end of the connecting post 11 is connected to the bottom surface of the groove 12, and the other end of the connecting post 11 passes through a through hole and extends to the side of the through hole away from the bottom surface of the groove 12. The axial direction of the connecting post 11 is the same as the depth direction of the groove 12.
[0040] In some embodiments of this utility model, such as Figure 4 As shown, the connecting post 11 includes a post body 111 and an abutment plate 112. The abutment plate 112 is disposed on the side of the post body 111 opposite to the bottom surface of the groove 12, and along the axial direction of the post body 111, the orthographic projection size of the abutment plate 112 is larger than the orthographic projection size of the post body 111. When the button 10 is configured to rebound, the two ends of the elastic member 30 along the axial direction of the post body 111 abut against the fixing member 20 and the abutment plate 112, respectively. In this embodiment, the abutment plate 112 is fixed to the side of the post body 111 opposite to the bottom surface of the groove 12, and can abut against the side of the elastic member 30 opposite to the bottom surface of the groove 12. When button 10 is pressed and rebounds, the abutment plate 112 can rebound with the column 111 and squeeze the elastic member 30 until the elastic member 30 is squeezed on the side of the fixing member 20 away from the bottom surface of the groove 12. Due to its own elasticity, the elastic member 30 can buffer the abutment plate 112 and the fixing member 20, and at the same time prevent the abutment plate 112 from sliding out through the through hole.
[0041] Specifically, in this embodiment, along the axial direction of the column 111, the projection of the elastic member 30 toward the abutment plate 112 is located inside the abutment plate 112, and the projection of the column 111 toward the abutment plate 112 is located inside the abutment plate 112, which can ensure that the abutment plate 112 squeezes the elastic member 30 when it rebounds.
[0042] In some embodiments of this utility model, such as Figure 4 As shown, a threaded hole 1111 is provided on the side of the column 111 facing away from the bottom surface of the groove 12, and a connecting hole is provided on the abutting plate 112. The button structure 100 also includes a bolt 40, which passes through the connecting hole and is threadedly connected to the threaded hole 1111. In this embodiment, the bolt 40 has a connected head and a threaded portion. The end of the threaded portion facing away from the head passes through the connecting hole and is inserted into the threaded hole 1111, so that the threaded portion and the threaded hole 1111 are threadedly engaged. After the bolt 40 is tightened, the abutting plate 112 can be fixed to the column 111, ensuring that the button 10 can drive the column 111 and the abutting plate 112 to move when it rebounds.
[0043] Specifically, in other embodiments of this utility model, the abutment plate 112 can also be welded to the column 111, which can also achieve a stable connection between the abutment plate 112 and the column 111. Welding connection is both labor-saving and time-saving, and does not reduce the cross-sectional area of the material, which can make full use of the material. In addition, the welded connection has greater structural rigidity, better overall integrity, and can withstand greater force and pressure.
[0044] Specifically, in other embodiments of this utility model, the abutment plate 112 and the fixing member 20 can also adopt other detachable connection methods, such as magnetic connection, where the column 111 is made of iron and the abutment plate 112 is made of magnetic material. This also enables the abutment plate 112 to be magnetically connected to the side of the column 111 away from the bottom surface of the groove 12.
[0045] In some embodiments of this utility model, the elastic element 30 is a first annular structure, which is sleeved on the outside of the column 111 and located between the abutment plate 112 and the fixing element 20. In this embodiment, the elastic element 30 is sleeved on the outside of the column 111 to prevent it from falling off the column 111, thus failing to achieve the buffering effect between the fixing element 20 and the abutment plate 112 when the button 10 rebounds.
[0046] Specifically, in other embodiments of this utility model, the elastic member 30 includes a connected elastic part and a snap-fit part. A sliding groove is provided on the outer peripheral surface of the column 111, extending along the axial direction of the column 111. The snap-fit part snaps into the sliding groove and can move along the axial direction of the column 111, thereby driving the elastic part to move along the axial direction of the column 111. When the button 10 is pressed and rebounds, the abutment plate 112 can squeeze the elastic part. Since the sliding part can move in the sliding groove, the elastic member 30 moves along the axial direction of the column 111 until both ends of the elastic member 30 along the axial direction of the column 111 abut against the fixing member 20 and the abutment plate 112, respectively. This not only buffers the rebound of the button 10, but also allows the button 10 to abut against the fixing member 20 through the column 111 and the elastic member 30, preventing the button 10 from falling out.
[0047] In some embodiments of this utility model, the elastic element 30 is a silicone element. In this embodiment, the silicone element, as a high-performance elastic material, adapts to complex deformation and can quickly return to its original shape after being compressed. After the button 10 rebounds, it can withstand the impact between the abutment plate 112 and the fixing element 20, thereby achieving a buffering effect and reducing the damage between the abutment plate 112 and the fixing element 20.
[0048] In some embodiments of this utility model, the button structure 100 further includes a support member located within the groove 12. The two ends of the support member along the axial direction of the column 111 are elastically connected to the fixing member 20 and the button 10, respectively. In this embodiment, the support member can consistently support the fixing member 20 and the button 10, ensuring that the button 10 can rebound due to elastic force after being pressed by an operator, thus guaranteeing the rebound capability of the button 10.
[0049] Specifically, in this embodiment, the support member can also be elastically connected to only one of the fixing member 20 and the button 10, and fixedly connected to the other of the fixing member 20 and the button 10, which can also achieve the effect of supporting and rebounding the button 10 through elastic force.
[0050] In some embodiments of this utility model, such as Figure 2 As shown, multiple connecting posts 11 are provided, multiple through holes are provided, and multiple elastic elements 30 are provided. Each connecting post 11 is connected to a corresponding through hole, and an elastic element 30 is provided between the fixing element 20 and each connecting post 11. In this embodiment, four connecting posts 11 are provided, all connected to the bottom surface of the groove 12 and spaced apart. Each of the four connecting posts 11 can pass through its corresponding through hole on the fixing element 20 and cooperate with its corresponding elastic element 30.
[0051] Specifically, in this embodiment, such as Figure 2 As shown, four abutment plates 112 are also provided. Each abutment plate 112 is connected to one side of a column 111 away from the bottom surface of the groove 12. Each elastic element 30 is sleeved on the outside of a column 111. When the button 10 rebounds, each elastic element 30 abuts against an abutment plate 112 and a fixing element 20 at both ends along the axial direction of the column 111.
[0052] In some embodiments of this utility model, such as Figure 4 As shown, the fixing member 20 includes a first plate 21 and a second plate 22. The second plate 22 has a second annular structure and surrounds the circumferential edge of the first plate 21 on the side opposite to the bottom surface of the groove 12. The first plate 21 and the second plate 22 together form a receiving cavity 23. The elastic member 30 is located in the receiving cavity 23, and the first plate 21 is provided with a through hole. In this embodiment, the receiving cavity 23 is used to accommodate the elastic member 30, the abutment plate 112, and part of the column 111, satisfying the stroke height of the button 10 after it is pressed.
[0053] In some embodiments of this utility model, the button structure 100 further includes a base plate 50, and the groove 12 has an opening on the side opposite to the bottom surface. The base plate 50 covers the opening and is connected to the second plate 22. In this embodiment, the base plate 50 is used to seal the groove 12 and also to support the second plate 22, so as to facilitate the movement of the button 10 relative to the fixing member 20.
[0054] Specifically, the assembly steps of the button structure 100 in this embodiment are as follows: first, a through hole is made in the column 111; then, the elastic element 30 is sleeved on the outside of the column 111; then, the abutment plate 112 is fixed to the column 111 by bolts 40 to prevent the elastic element 30 from falling off the column 111; finally, the base plate 50 is sealed over the opening and connected to the second plate 22. After the button 10 is pressed and rebounds, the elastic element 30 will abut against the second plate 22 and the abutment plate 112 respectively.
[0055] Furthermore, in this invention, the post 111 of the button 10 is fitted with a fixing member 20, and then the post 111 is fitted with an elastic member 30 and pressed down by an abutment plate 112. Finally, the abutment plate 112 is fixed to the post 111 by bolts 40. When the button 10 is not pressed, the abutment plate 112 can exert a certain pressure on the elastic member 30, ensuring that the button 10 is abutted and fixed to the fixing member 20. Moreover, by compressing and deforming the elastic member 30, the button 10 can move up and down relative to the fixing member 20, thereby achieving the purpose of pressing and vibrating the button 10.
[0056] This utility model also proposes an electronic device having the above-described button structure 100.
[0057] By using the electronic device in this technical solution, the electronic device in this embodiment can be a handle or a mobile phone. Most handles or mobile phones have a button structure 100. Using the button structure 100 in this utility model, the button 10 can be pressed or rebounded, thereby moving relative to the fixing member 20 along the axial direction of the connecting post 11. When the button 10 rebounds, the two ends of the elastic member 30 along the axial direction of the connecting post 11 can respectively abut against the fixing member 20 and the connecting post 11, so that the button 10 can be buffered when it rebounds, and the button 10 is abutted against the fixing member 20 through the connecting post 11 and the elastic member 30, preventing the button 10 from falling out.
[0058] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
