[0037] Figure 1 A 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 A schematic diagram of the button structure 100 from another perspective. Figure 3 for Figure 2 A schematic diagram of the cross-sectional structure along the AA direction. (See diagram below.) Figure 1 , 2 As shown in Figure 3, 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 ring 30. The button 10 has a groove 11, and the side of the groove 11 facing away from the bottom surface has an opening. The fixing member 20 is disposed in the groove 11, and the elastic ring 30 is disposed on the side of the fixing member 20 facing away from the bottom surface of the groove 11. The inner circumference of the elastic ring 30 is connected to the fixing member 20, and the outer circumference of the elastic ring 30 is connected to the edge of the opening. The elastic ring 30, the button 10, and the fixing member 20 enclose a sealed cavity.

[0038] By using the button structure 100 in this technical solution, the inner and outer circumferences of the elastic ring 30 are connected to the button 10 and the fixing member 20 respectively, which can ensure the sealing of the sealing cavity and prevent external impurities from entering the sealing cavity and causing the button structure 100 to malfunction. In addition, since the elastic ring 30 itself is elastic, it can ensure that the button 10 maintains the seal of the sealing cavity during the movement of the button 10 relative to the fixing member 20, thus improving reliability.

[0039] Specifically, in this embodiment, after the button 10 is pressed by the operator, because the fixing member 20 is a fixed structure, the bottom surface of the groove 11 of the button 10 will move towards the fixing member 20, causing the outer periphery of the elastic ring 30 to be pressed by the button 10, thereby deforming. When the button 10 rebounds after being pressed, the bottom surface of the groove 11 of the button 10 will move away from the fixing member 20, causing the outer periphery of the elastic ring 30 to return to its original shape. The presence of the elastic ring 30 not only seals the sealing cavity enclosed by the elastic ring 30, the fixing member 20, and the button 10, but also ensures that the sealing cavity remains sealed at all times during the pressing or rebounding process of the button 10, thus improving reliability.

[0040] In some embodiments of this utility model, such as Figure 3 As shown, the elastic ring 30 includes a first ring body portion 32, a second ring body portion 33, and a ring body connecting portion 31. The first ring body portion 32 is connected to the outer periphery of the ring body connecting portion 31, and the second ring body portion 33 is connected to the inner periphery of the ring body connecting portion 31. The first ring body portion 32 is attached to the side of the fixing member 20 facing away from the bottom surface of the groove 11, and the second ring body portion 33 is attached to the edge of the opening. In this embodiment, the first ring body portion 32 is attached to the side of the fixing member facing away from the bottom surface of the groove 11, and the second ring body portion 33 is attached to the edge of the opening, so that the elastic ring 30 can be connected to the opening and the fixing member 20 from the side facing away from the bottom surface of the groove 11 respectively.

[0041] Specifically, in this embodiment, the first ring body 32 is attached to the outer peripheral edge of the fixing member 20 on the side opposite to the bottom surface of the groove 11, which can reduce the area of ​​the overall elastic member and thus save the cost of the overall button structure 100.

[0042] Specifically, in other embodiments of this utility model, the elastic ring 30 is located in the groove 11, and the first ring body 32 is connected to the side of the fixing member 20 facing the side wall of the groove 11, and the second ring body 33 is connected to the side wall of the groove 11. This can also achieve the purpose of forming a sealing cavity by the sealing ring, the fixing member 20 and the button 10, and can also achieve the function of sealing the sealing cavity by the elastic ring 30.

[0043] In some embodiments of this utility model, such as Figure 3 As shown, a first plastic part 40 is provided between the first ring body portion 32 and the fixing member 20. In this embodiment, the first plastic part 40 can increase the hardness at the position of the first ring body portion 32, which facilitates a rigid connection with the fixing member 20 through the first plastic part 40, and can strengthen the connection strength between the first ring body portion 32 and the fixing member 20 through the first plastic part 40.

[0044] In some embodiments of this utility model, the first plastic part 40 and the fixing part 20 are bonded or welded together. In this embodiment, the fixing part 20 may be made of a different material than the first plastic part 40. Bonding can achieve the connection of dissimilar materials such as metal, plastic, glass, and ceramic, and the bonding surface is subjected to stress as a whole, avoiding local stress concentration as in riveting or screwing, significantly improving fatigue resistance. In addition, the process is simple and efficient, improving connection efficiency.

[0045] Specifically, in this embodiment, the first plastic part 40 and the first ring body 32 are bonded or welded together. The first ring body 32 is a silicone part, which is made of a different material than the first plastic part 40. Bonding can achieve the connection of dissimilar materials such as metal, plastic, glass, and ceramic, and the bonding surface is subjected to stress as a whole, avoiding local stress concentration as in riveting or screwing, significantly improving fatigue resistance. In addition, the process is simple and efficient, improving the connection efficiency.

[0046] In some embodiments of this utility model, such as Figure 3 As shown, a second plastic part 50 is provided between the second ring body portion 33 and the button 10. In this embodiment, the second plastic part 50 can increase the hardness at the position of the second ring body portion 33, making it easier to achieve a rigid connection with the button 10 through the second plastic part 50, and strengthening the connection strength between the second ring body portion 33 and the button 10 through the second plastic part 50.

[0047] In some embodiments of this utility model, the second plastic part 50 and the button 10 are bonded or welded together. In this embodiment, the button 10 may be made of a different material than the second plastic part 50. Bonding can connect dissimilar materials such as metal, plastic, glass, and ceramic, and the bonding surface is subjected to stress as a whole, avoiding local stress concentration as with riveting or screwing, significantly improving fatigue resistance. In addition, the process is simple and efficient, improving connection efficiency.

[0048] Specifically, the second plastic part 50 and the second ring body 33 are bonded or welded together. The second ring body 33 is made of silicone, which is a different material from the second plastic part 50. Bonding can connect dissimilar materials such as metal, plastic, glass, and ceramic, and the bonding surface is subjected to stress as a whole, avoiding local stress concentration as in riveting or screwing, significantly improving fatigue resistance. In addition, the process is simple and efficient, improving connection efficiency.

[0049] In some embodiments of this utility model, the first plastic part 40, the second plastic part 50, and the elastic ring 30 are injection molded integral parts. The first plastic part 40 is a PC (polycarbonate) or ABS (acrylonitrile butadiene styrene) component, and the second plastic part 50 is a PC or ABS component. In this embodiment, two-color injection molding is used to form the first plastic part 40, the second plastic part 50, and the elastic ring 30 into an integral structure, which avoids gaps caused by traditional assembly and improves waterproof and dustproof performance. The first plastic part 40 and the second plastic part 50 can both be ABS, or both can be PC, or one can be PC and the other ABS. Both PC and ABS components have high strength and hardness, which can increase the hardness at the location of the first ring body 32 or the second ring body 33, facilitating improved connection strength with the fixing member 20 or the button 10.

[0050] In some embodiments of this utility model, such as Figure 3 As shown, the ring-shaped connecting portion 31 protrudes towards the side opposite to the bottom surface of the groove 11. In this embodiment, the above-mentioned arrangement allows the ring-shaped connecting portion 31 to be longer, enabling it to withstand a larger pressing stroke of the button 10 after it is pressed, thereby improving reliability and applicability.

[0051] In some embodiments of this utility model, the elastic ring 30 is a silicone component. In this embodiment, the silicone component, as a high-performance elastic material, adapts to complex deformations and can maintain a seal on the sealing cavity during the movement of the button 10 relative to the fixing member 20, thereby improving reliability.

[0052] In some embodiments of this utility model, the button structure 100 further includes a support member located within the groove 11. The two ends of the support member along the depth direction of the groove 11 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.

[0053] 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.

[0054] Furthermore, in this embodiment, the elastic ring 30 is formed by two-color injection molding of silicone and PC or ABS parts, thus combining the toughness and deformability of silicone with the edge hardness of plastic. The button 10 and the elastic ring 30 are joined together by adhesive dispensing or ultrasonic welding, and the fixing member 20 is also joined to the elastic ring 30 by adhesive dispensing or ultrasonic welding. There is no connection between the button 10 and the fixing member 20, which ensures both a sealed and waterproof cavity while allowing relative movement between the button 10 and the fixing member 20.

[0055] This utility model also proposes an electronic device having the above-described button structure 100.

[0056] The electronic device in this embodiment can be a handle or a mobile phone. By using the button structure 100 of the handle or mobile phone, the inner and outer circumferences of the elastic ring 30 are connected to the button 10 and the fixing member 20 respectively, which can ensure the sealing of the sealed cavity and prevent external impurities from entering the sealed cavity and causing the button structure 100 to malfunction. In addition, since the elastic ring 30 itself is elastic, the button 10 can move relative to the fixing member 20, which facilitates the pressing operation of the button 10.

[0057] 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.
