[0023] In some electronic devices, physical button structures are still used for practicality and reliability. These button structures typically include active pressing parts and rebound parts. The large number of parts makes it difficult to assemble the button structure into the housing of the electronic device.
[0024] In view of this, the present invention provides a button structure and electronic device, which at least aims to improve the problem of difficult assembly caused by the large number of components in the existing button structure.
[0025] To facilitate understanding of this utility model, a button structure is provided, which is described below in conjunction with the accompanying drawings.

[0027] Please see Figures 2 to 4In one embodiment of this utility model, the button structure 100 includes a housing 1 and a button 2. The housing 1 has an inner side 1a and an outer side 1b in a first direction X. The housing 1 has an elastic shell wall 11, and the elastic shell wall 11 forms a mounting hole 111 that passes through along the first direction X. The button 2 includes a pressing part 21 and a touching protrusion 22 connected to each other. The pressing part 21 is disposed at the outer side 1b end of the elastic shell wall 11. The touching protrusion 22 passes through the mounting hole 111 and extends into the inner side 1a of the housing 1. The touching protrusion 22 is in sealing contact with the inner wall of the mounting hole 111. The elastic shell wall 11 is configured to elastically deform inward when the pressing part 21 is subjected to external pressure, and to drive the pressing part 21 to reset outward when the pressing part 21 loses external pressure.
[0028] It should be noted that "the housing 1 has an elastic shell wall 11" can be understood as the entire housing 1 being made of elastic shell walls 11, or only a partial area of the housing 1 being made of elastic shell walls 11; the pressing part 21 is located at the outer 1b end of the elastic shell wall 11, that is, at the outer 1b of the housing 1. The specific size of the exposed part of the pressing part 21 depends on the specific shape of the housing 1, but the pressing part 21 should at least be operable by the user; the touch protrusion 22 is in sealed contact with the inner wall of the mounting hole 111, where "sealed contact" means that there is no assembly gap between the touch protrusion 22 and the inner wall of the mounting hole 111. This sealing method can be achieved by pre-pressing the touch protrusion 22 with the elastic deformation of the elastic shell wall 11 itself, or by applying sealant to the touch protrusion 22 before installing it into the mounting hole 111. This embodiment does not limit this. The elastic shell wall 11 is configured to elastically deform inward when the pressing part 21 is subjected to external pressure, and to drive the pressing part 21 to reset outward when the external pressure is lost, so that the elastic shell wall 11 can act as a rebound component and drive it to reset after the user presses the pressing part 21; the material of the elastic shell wall 11 in this embodiment of the present invention can usually be selected as soft rubber material.
[0029] The technical solution provided by this utility model is that the housing 1 of the button structure 100 has an elastic shell wall 11, on which a mounting hole 111 is formed. The touch protrusion 22 of the button 2 can directly pass through the mounting hole 111 and extend into the inner side 1a of the housing 1 to contact the touch switch. Since the elastic shell wall 11 is part of the housing 1, and the elastic shell wall 11 is configured to elastically deform inward when the pressing part 21 is subjected to external pressure, and drive the pressing part 21 to reset outward when the external pressure is lost, the elastic shell wall 11 of the housing 1 can act as a rebound component to drive the pressing part 21 to rebound, thereby reducing the number of components of the button structure 100 and reducing the assembly difficulty of the button structure 100. Moreover, since the elastic shell wall 11 is part of the housing 1, and the touch protrusion 22 is in sealed contact with the inner wall of the mounting hole 111 on the elastic shell wall 11, the path of communication between the inside and outside of the housing 1 can be blocked, thereby improving the waterproof performance of the button structure 100.
[0030] Please see Figure 4 and Figure 5 In one embodiment, the end of the touch protrusion 22 that extends into the inner side 1a of the housing 1 is defined as the touch end 221, and the touch end 221 has an annular protrusion 221a on the periphery.
[0031] It should be noted that the periphery of the touch end 221 refers to its periphery projected along the first direction X, and the annular protrusion 221a is part of the touch end 221. Based on the elastic contraction and expansion characteristics of the elastic shell wall 11, in this technical solution, an annular protrusion 221a is provided on the periphery of the touch end 221 of the touch protrusion 22. This annular protrusion 221a can abut against the elastic shell wall 11, thereby preventing the touch protrusion 22 from dislodging from the mounting hole 111 of the elastic shell wall 11, ensuring the reliability of the button structure 100.
[0032] Please see Figure 4 In one embodiment, the cross-section of the touch end 221 gradually decreases in the direction away from the pressing part 21.
[0033] It should be noted that the cross-section of the touch end 221 gradually decreases in the direction away from the pressing part 21, that is, the cross-section of the touch end 221 gradually decreases in the direction towards the inner side 1a of the housing 1. This technical solution enables the touch end 221 to have a certain positioning and auxiliary expansion function of the mounting hole 111 during the process of inserting the touch protrusion 22 into the elastic housing wall 11, under the premise of having the annular protrusion 221a, which helps to reduce the installation difficulty.
[0034] Please refer to the following: Figure 5In one embodiment, the mounting hole 111 has an expansion hole section 1111 and a sealing hole section 1112 in a first direction X. The expansion hole section 1111 is disposed closer to the outer side 1b of the housing 1 than the sealing hole section 1112. The contact protrusion 22 makes sealing contact with the inner wall of the sealing hole section 1112.
[0035] In the above technical solution, the design of the expansion hole section 1111 enables the touch protrusion 22 to be positioned and guided by the expansion hole section 1111 during the process of being inserted into the mounting hole 111, which is beneficial for the touch protrusion 22 to be pushed open and enter the mounting hole 111.
[0036] Please see Figure 4 and Figure 5 In one embodiment, the housing 1 further has a rigid shell wall 12, which surrounds the elastic shell wall 11 and is sealed to the elastic shell wall 11.
[0037] It should be noted that the hardness of the rigid shell wall 12 is generally higher than that of the elastic shell wall 11. It is usually difficult for human force to deform the rigid shell wall 12 by pressing. The materials of the rigid shell wall 12 and the elastic shell wall 11 are usually hard plastic and soft rubber, respectively. This embodiment of the present invention does not limit this. The rigid shell wall 12 is arranged around the elastic shell wall 11 and is sealed to the elastic shell wall 11. There are various ways to seal the connection, such as bonding the two by sealant or pre-pressing. This embodiment does not limit this.
[0038] In the above technical solution, the shell 1 is configured to be composed of a rigid shell wall 12 and an elastic shell wall 11, which can obtain sufficient support strength. Moreover, since the rigid shell wall 12 is arranged around the elastic shell wall 11 and is sealed to the elastic shell wall 11, it is beneficial to ensure the waterproof performance of the shell 1.
[0039] In one embodiment, the rigid shell wall 12 and the elastic shell wall 11 are integrally injection molded.
[0040] In the above technical solution, the rigid shell wall 12 and the elastic shell wall 11 are integrally injection molded, resulting in a higher connection strength between the rigid shell wall 12 and the elastic shell wall 11. Furthermore, the molding method is simple and efficient, and there is no need to consider the sealing between the rigid shell wall 12 and the elastic shell wall 11.
[0041] Please see Figure 5 In one embodiment, the elastic shell wall 11 and the rigid shell wall 12 are respectively formed with mutually fitting protrusions 112a and recesses 121a at their connection positions.
[0042] It should be noted that at the connection point between the elastic shell wall 11 and the rigid shell wall 12, i.e., the connection interface between the elastic shell wall 11 and the rigid shell wall 12, a recess 121a and a protrusion 112a are respectively formed at their connection interface. The recess 121a can be formed on the elastic shell wall 11 and the protrusion 112a on the rigid shell wall 12, or vice versa. This embodiment does not limit this. In the above technical solution, the interlocking arrangement of the recess 121a and the protrusion 112a increases the area of the connection interface between the elastic shell wall 11 and the rigid shell wall 12, thereby improving the connection strength between the elastic shell wall 11 and the rigid shell wall 12.
[0043] Please see Figure 5 In one embodiment, a first joint 112 is formed on the periphery of the elastic shell wall 11; a second joint 121 is formed on the rigid shell wall 12 corresponding to the first joint 112, the first joint 112 is sealed to the second joint 121, and is disposed near the outer side 1b of the shell 1.
[0044] In the above technical solution, the first joint portion 112 of the elastic shell wall 11 is positioned closer to the outer side 1b of the shell 1 than the second joint portion 121 of the hard shell wall 12. This allows the first joint portion 112 and the second joint portion 121 to mainly bear the compressive stress when the user presses the button 2, which helps to prevent the connection between the elastic shell wall 11 and the hard shell wall 12 from failing.
[0045] Please see Figure 4 and Figure 5 In one embodiment, the elastic shell wall 11 is arched outward.
[0046] In the above technical solution, the elastic shell wall 11 is arched outward to form a cover-like structure. When the user presses the button 2, the arched elastic shell wall 11 can provide the user with a larger pressing stroke, thereby improving the user's operating experience. At the same time, the arched elastic shell wall 11 is also conducive to improving the rebound performance of the elastic shell wall 11.
[0047] Please see Figure 4 In one embodiment, in the projection of the first direction X, the pressing part 21 is partially overlapped with the rigid shell wall 12.
[0048] Based on the fact that the pressing part 21 is located on the outer side 1b of the housing 1, in the above technical solution, the pressing part 21 is set to partially overlap with the hard shell wall 12. When the user presses the button 2, the hard shell wall 12 can limit the movement of the pressing part 21, thereby avoiding the situation where the elastic shell wall 11 breaks due to excessive pressing of the button 2 by the user.
[0049] Please see Figure 4 and Figure 5 In one embodiment, a portion of the rigid shell wall 12 is recessed toward the inner side 1a of the shell 1 to form a receiving groove 122, and the elastic shell wall 11 is located at the bottom wall of the receiving groove 122; wherein, the pressing part 21 is accommodated in the receiving groove 122.
[0050] In the above solution, a portion of the hard shell wall 12 is recessed to form a receiving groove 122, while the elastic shell wall 11 is located at the bottom wall of the receiving groove 122. This allows the pressing part 21 to be accommodated in the receiving groove 122, making the button structure 100 more aesthetically pleasing. At the same time, the receiving groove 122 also protects the pressing part 21, preventing it from falling off due to lateral impact.
[0051] Please see Figure 1 This utility model also proposes an electronic device 1000, which includes a roof structure and a button structure 100 as described in any of the above embodiments. The specific structure of the button structure 100 is as described in the above embodiments. Since this electronic device 1000 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The electronic device 1000 can be any device that requires the use of the button structure 100, such as a mobile phone, tablet computer, or monitor. This utility model embodiment does not limit the specific type of the electronic device 1000.
[0052] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
