[0044] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0045] Figure 1 This is a schematic diagram of the terminal device structure in related technologies. For example... Figure 1 As shown, the terminal device includes: a housing 110, a button 120, a side strip 130, and a plug 140. The housing 110 has a mounting groove and a through hole communicating with the mounting groove. The plug 140 is located within the through hole and is a single-end open cylindrical shape, with the single-end opening facing the button groove. To achieve waterproofing, a rubber stopper seals the through hole and the plug 140. The button 120 is at least partially located within the mounting groove. The button 120 has a button post facing the mounting groove, at least a portion of which extends into the plug 140 and abuts against it. The side strip 130 is located within the mounting groove and between the groove wall of the button groove and the button 120. The button 120 includes symmetrically distributed button skirts 121 on both sides. The side strip 130 fixes the button 120 by limiting the movement of the button skirts 121. The edge strip 130 is fixed to the housing 110 by foam adhesive or fasteners, and the edge strip 130 can also shield the plug 140 inside the housing 110. When the user needs to operate the terminal device, pressing the button 120 or pressing the plug 140 will press the electronic switch on the adjacent circuit board.

[0046] Assembly Figure 1 When installing the terminal device shown, the plug 140 needs to be installed in the through hole first, then a rubber plug is used to seal the plug 140 and the side wall of the through hole, and the plug 140 is then fixed in place. After the plug 140 is fixed, the button 120 is installed, and then the side strip 130 is fixed to the housing 110. When it is necessary to remove the button 120, the side strip 130 must be removed first before the button 120 can be removed, which complicates the removal of the button 120, makes it inconvenient to repair or replace the button 130, and the removed side strip 130 will be deformed and rendered unusable.

[0047] The use of the side strip 130 in the terminal device occupies a certain amount of space, which is not conducive to the miniaturization or compactness of the housing 110, and also affects the shape of the housing 110. As an independent structural component, the side strip 130 needs to be molded and assembled separately, which increases costs. Using the side strip 130 to fix the button 120, the exposed side strip 130 will also affect the appearance of the terminal device.

[0048] A plug 140 is provided between the button post and the through hole. The plug 140 occupies a large space, which will increase the size of the through hole and thus increase the size of the housing 110 at that location, which is not conducive to the thin and light design of the terminal device.

[0049] Therefore, this application provides a terminal device that solves the problem of inconvenient button removal and achieves miniaturization and thinning of the terminal device.

[0050] It should be noted that the terminal device mentioned in this application can be an electronic product such as a mobile phone, smartwatch, tablet computer, laptop computer, or e-reader. Taking a mobile phone as an example, the buttons on a mobile phone can be, for example, a power button and volume buttons.

[0051] Please see Figure 2 , Figure 2 This is a schematic diagram of a terminal device structure provided in an embodiment of this application. Here, the terminal device is illustrated using a mobile phone as an example. The terminal device may include: a housing 210 and buttons 220.

[0052] To see the structure of button 220 in the terminal device more clearly, please refer to [link / reference]. Figures 3-4 , Figure 3 and Figure 4 yes Figure 2 Enlarged view of the partial structure at button 220.

[0053] Figure 3 This is a three-dimensional structural diagram of a terminal device provided in an embodiment of this application. Figure 4 This is a schematic cross-sectional view of a terminal device provided in an embodiment of this application.

[0054] Please see Figures 3-4 This application provides a terminal device, wherein the housing 210 has an assembly groove 211 and a docking groove 212 communicating with the assembly groove 211.

[0055] The button 220 includes: a button body 221, and a positioning post 222 fixedly connected to the side of the button body 221 facing the housing 210. For a clearer view of the structure of the positioning post 222, please refer to [reference needed]. Figures 5-6 , Figure 5 This is a schematic diagram of a three-dimensional button structure provided in an embodiment of this application. Figure 6 yes Figure 5 A three-dimensional structural diagram of the center button from another perspective shows that the positioning post 222 of the button 220 has a limiting buckle 2221 at the end away from the button body 221. The positioning post 222 also has a disassembly groove 2222, and a first slot 2223 and a second slot 2224 communicating with the disassembly groove 2222. The first slot 2223 is distributed on the side wall of the positioning post 222, and the second slot 2224 is distributed on the end face of the positioning post 222 away from the button body 221.

[0056] The button body 221 is at least partially located in the assembly groove 211, and the limit buckle 2221 is engaged with the housing 210 through the docking groove 212.

[0057] The terminal device provided in the above embodiments of this application allows the limiting buckle to engage with the housing via a mating groove, meaning the button and housing are directly engaged without the need for intermediate components (such as edge strips) for fixation. This simplifies the number of fixing structural components for the button, thereby simplifying the installation and removal operations. The positioning post has a disassembly groove, and a first and second slot communicating with it, providing a certain deformation space for the limiting buckle. This allows the limiting buckle to easily engage with the housing during button installation, facilitating button installation, or to easily disengage from the housing during button removal.

[0058] Please see Figure 3 When it is necessary to disassemble button 220, the entire machine does not need to be disassembled. Simply insert a thin piece between button 220 and the mounting slot 211, and pry button 220 using the thin piece or a structure containing it. The limiting buckle 2221 will be deformed under pressure, disengaging from the mating slot 212, thus disassembling button 220. At this point, the user can replace button 220 themselves, for example, by replacing it with a button of a different color. When replacing button 220, the user only needs to align button 220 and mounting slot 211 or align positioning post 222 and mating slot 212. By pressing button 220, the limiting buckle 2221 will be pressed into the mating slot 212, achieving a snap-fit ​​connection between button 220 and housing 210. The entire process of disassembling and assembling button 220 is convenient, quick, simple, and efficient. Users can replace it themselves, and after-sales maintenance is convenient.

[0059] Since the button 220 in the terminal device provided in this application embodiment does not require intermediate parts for fixation, but can be fixed to the housing 210 through its own structure, intermediate parts can be eliminated, thereby achieving miniaturization or compactness of the terminal device. Typically, buttons 220 in terminal devices are located on the side, such as the buttons 220 on a mobile phone. Eliminating intermediate parts allows for a thinner and lighter terminal device, and also facilitates a simplified design to meet different shape requirements.

[0060] It is understood that, in the terminal device provided in this application embodiment, when the button 220 is disassembled, the design of the disassembly groove, the first groove 2223 and the second groove 2224 facilitates the deformation of the limiting buckle 2221, so that the limiting buckle 2221 can be disengaged from the docking groove 212. The button 220 can maintain the integrity of the structure when disassembled, and the button 220 can be reused multiple times.

[0061] In one possible implementation, the first slot 2223 extends axially along the positioning post 222 to the end face of the positioning post 222 away from the button body 221. Alternatively, the second slot 2224 extends radially along the positioning post 222 to the side wall of the positioning post 222. Still another possibility is that the first slot 2223 extends axially along the positioning post 222 to the end face of the positioning post 222 away from the button body 221, and the second slot 2224 extends radially along the positioning post 222 to the side wall of the positioning post 222.

[0062] When the first slot 2223 extends axially along the positioning post 222 to the end face of the positioning post 222 away from the button body 221, it facilitates the deformation of the limiting buckle 2221. When the second slot 2224 extends radially along the positioning post 222 to the side wall of the positioning post 222, it also facilitates the deformation of the limiting buckle 2221. When the first slot 2223 extends axially along the positioning post 222 to the end face of the positioning post 222 away from the button body 221, and the second slot 2224 extends radially along the positioning post 222 to the side wall of the positioning post 222, it facilitates the deformation of the limiting buckle 2221, thereby easily enabling the installation or removal of the button 220.

[0063] For details, please refer to Figure 6 Part of the edge of the first slot 2223 coincides with part of the edge of the second slot 2224. At this time, the limiting buckle 2221 is a block that protrudes radially outward along the positioning post 222, and a notch is formed along the circumference of the positioning post 222, which coincides with part of the first slot 2223.

[0064] By having part of the edge of the first slot 2223 overlap with part of the edge of the second slot 2224, the limiting buckle 2221 can obtain a larger deformation space, reducing the resistance of the limiting buckle 2221 during deformation, and making it easy to install or remove the button 220.

[0065] It should be noted that when the limit buckle 2221 deforms, the disassembly groove 2222, the first groove 2223, and the second groove 2224 also deform.

[0066] For example, please refer to Figure 6 The length of the disassembly groove 2222 along the axial direction of the positioning post 222 and the length of the first slot 2223 along the axial direction of the positioning post 222 are the same, and both are greater than the length of the limit buckle 2221 along the axial direction of the positioning post 222. Thus, when installing or removing the button 220, in addition to the limit buckle 2221 being deformable, at least a portion of the positioning post 222 located between the limit buckle 2221 and the button body 221 can also be deformed. This allows the limit buckle 2221 and at least a portion of the positioning post 222 located between the limit buckle 2221 and the button body 221 to move closer to each other circumferentially at the first slot 2223, reducing the radial dimension of the limit buckle 2221 and at least a portion of the positioning post 222, that is, reducing the circumferential dimension of the first slot 2223 on the positioning post 222, facilitating the entry or exit of the limit buckle 2221 into or out of the mating groove 212.

[0067] It is understandable that the circumferential deformation mentioned here refers to the main deformation direction of the limit buckle 2221 and at least part of the positioning post 222, but deformation in other directions is not excluded. For example, the limit buckle 2221 and at least part of the positioning post 222 may also deform in the axial direction.

[0068] Figure 7 This is a schematic diagram of a cross-sectional structure of another terminal device provided in an embodiment of this application. Figure 8 This is a schematic diagram of another three-dimensional structure of a terminal device provided in an embodiment of this application. Figure 9 This is a schematic diagram of a terminal device planar structure provided in an embodiment of this application.

[0069] Please see Figures 7-9 In one feasible implementation, the terminal device further includes: a buffer pad 230, a guide post 240, and a circuit board 250.

[0070] Figure 10 This is a schematic diagram of a three-dimensional shell structure provided in an embodiment of this application. Please refer to it. Figure 10The housing 210 also has a through hole 213 communicating with the mounting groove 211. At least a portion of the guide post 240 is located within the through hole 213, and one end of the guide post 240 is connected to the button body 221, while the other end abuts against the buffer pad 230. The side of the buffer pad 230 facing away from the guide post 240 abuts against the electronic switch 251 disposed on the side of the circuit board 250 facing the buffer pad 230.

[0071] The guide post 240 is typically made of a relatively hard material, such as stainless steel or plastic. Prolonged pressure from the hard guide post 240 on the electronic switch 251 can cause deformation and damage to the switch. The buffer pad 230 prevents the guide post 240 from directly contacting the electronic switch 251 on the circuit board 250, effectively protecting the electronic switch 251 on the circuit board 250.

[0072] For example, the buffer pad 230 is made of an elastic material to enhance the feel of the button 220 and protect the electronic switch 251. The elastic material can be silicone, rubber, etc. Specifically, the buffer pad 230 is a TPU (thermoplastic polyurethane elastomer rubber) soft pad. The TPU soft pad has the function of preventing electrostatic discharge from damaging the electronic switch 251.

[0073] Figure 11 This is a schematic diagram of a three-dimensional structure of a cushioning pad provided in an embodiment of this application. Please refer to it. Figure 7 and Figure 11 In one feasible implementation, the buffer pad 230 has a relief groove 231 on the side facing the guide post 240, and the end of the guide post 240 away from the button body 221 abuts against the buffer pad 230 in the relief groove 231.

[0074] The relief groove 231 reduces the thickness of the buffer pad 230 that abuts against the guide post 240, making the buffer pad 230 at the relief groove 231 relatively thinner. This allows for greater deformation when pressed and provides a faster rebound after the user releases the button 220, resulting in better tactile feedback. The buffer pad 230 outside the relief groove 231 is relatively thicker to provide support.

[0075] Figure 12 yes Figure 11 Please refer to the three-dimensional structural diagram of the buffer pad from another perspective. Figures 11-12 In one possible implementation, the sidewall of the buffer pad 230 has an opening 232 that communicates with the groove wall of the clearance groove 231.

[0076] Please see Figures 7-8 The opening 232 allows the guide post 240 to be avoided, facilitating the installation or removal of the buffer pad 230.

[0077] If in Figure 11 An opening 232 communicating with the clearance groove 231 is also provided on the side directly opposite the opening 232 shown in the buffer pad 230, which weakens the support of the sidewall of the buffer pad 230. Therefore, please refer to Figure 11 The sidewall of the buffer pad 230 has an opening 232, and the other sidewalls of the buffer pad 230 outside the opening 232 are used to provide support to maintain the recessed structure at the clearance groove 231.

[0078] Please see Figure 12 In one possible implementation, the buffer pad 230 has an abutment block 233 on one side away from the guide post 240, and the abutment block 233 abuts against the electronic switch 251.

[0079] The projection of the abutting block 233 onto the button body 221 overlaps with the projection of the relief groove 231 onto the button body 221.

[0080] By overlapping the orthographic projection of the abutment block 233 on the button body 221 with the orthographic projection of the relief groove 231 on the button body 221, the interference area or abutment area between the abutment block 233 and the electronic switch 251 can be reduced. When the abutment block 233 and the electronic switch 251 have a small abutment area or interference area, the adaptability of the buffer pad 230 can be improved, making it easier for the buffer pad 230 to be adapted to various sizes or models of electronic switches 251.

[0081] Figure 13 yes Figure 10 Please refer to the three-dimensional structural diagram of the middle shell from another perspective. Figure 13 In one feasible embodiment, the housing 210 also has a mounting groove 214, which is located on the side of the through hole 213 away from the mounting groove 211 and communicates with the through hole 213.

[0082] Please see Figures 7-8 Both the circuit board 250 and the buffer pad 230 are located in the mounting groove 214, and the buffer pad 230 is closer to the button body 221 than the circuit board 250.

[0083] By opening a mounting groove 214 on the housing 210 to accommodate the circuit board 250 and the buffer pad 230, there is no need to specially set up a bracket to fix the buffer pad 230 and the circuit board 250, which simplifies the structural components of the terminal device and facilitates the miniaturization or compact design of the terminal device.

[0084] Please see Figure 7 In one feasible implementation, the guide post 240 includes: a first guide post 241 and a second guide post 242 arranged separately.

[0085] The first guide post 241 is fixedly connected to the side of the button body 221 facing the circuit board 250. The end of the first guide post 241 away from the button body 221 abuts against the end of the second guide post 242. The end of the second guide post 242 away from the first guide post 241 abuts against the buffer pad 230.

[0086] At least a portion of the second guide post 242 is located within the through hole 213.

[0087] Specifically, the second guide post 242 can be partially located inside the through hole 213, and the other part can be located outside the through hole 213 on the side away from the button body 221. In this case, part of the first guide post 241 is located inside the through hole 213, so that the first guide post 241 and the second guide post 242 can abut against each other. Alternatively, both ends of the second guide post 242 can be located outside the through hole 213, and the part of the second guide post 242 between the two ends can be located inside the through hole 213. In this case, the first guide post 241 is outside the through hole 213, so that it can abut against the second guide post 242.

[0088] Waterproofing is becoming increasingly important in terminal devices, and as part of a terminal device, the Button 220's waterproofing is also essential.

[0089] Figure 14 This is an exploded view of a terminal device provided in an embodiment of this application. Please refer to [link / reference]. Figure 14 Specifically, in one feasible implementation, the second guide post 242 includes: a guide post body 2421, and a sealing ring 2422 sleeved and fixed on the guide post body 2421, the sealing ring 2422 abutting against the inner wall of the through hole 213.

[0090] The waterproofing requirements of the terminal equipment are met by the internal contact between the sealing ring 2422 and the through hole 213.

[0091] The guide post body 2421 and the sealing ring 2422 occupy relatively less space, which is conducive to the miniaturization or compactness of the terminal equipment.

[0092] Please see Figure 14 For example, a sealing ring 2422 is integrally injection molded on the guide post body 2421. The sealing ring 2422 is a liquid silicone ring, and the outer wall of the sealing ring 2422 is an arc-shaped annular surface.

[0093] The guide post body 2421 and the sealing ring 2422 are integrally injection molded, so there is no problem with the sealing ring 2422 falling off or being installed, and it is also convenient to install part of the second guide post 242 in the through hole 213.

[0094] The outer wall of the sealing ring 2422 is an arc-shaped annular surface, and the interference with the through hole 213 is relatively small. When the button 220 is pressed, the friction between the sealing ring 2422 and the through hole 213 is smaller, which helps to ensure the pressing feel of the button 220.

[0095] Figure 15 This is a schematic cross-sectional view of a shell structure provided in an embodiment of this application. Please refer to... Figure 15 In one feasible implementation, the sidewall of the docking groove 212 has a step 215, the side of the step 215 facing away from the button body 221 is used to engage with the limit buckle 2221.

[0096] Please see Figures 5-6 Specifically, in one feasible embodiment, the button body 221 is elongated, and its outer periphery is racetrack-shaped (i.e., an elongated ellipse). The button 220 has two positioning posts 222 and one guide post 240. The two positioning posts 222 are spaced apart along the length of the button body 221, and the guide post 240 is located between the two positioning posts 222 (at the midpoint). The mating grooves 212 on the housing 210 correspond one-to-one with the positioning posts 222.

[0097] The elongated button body 221, through two positioning posts 222, can stably and firmly install the button 220 on the housing 210, and the button 220 is not prone to shaking or loosening.

[0098] This application does not impose any restrictions on the number of positioning posts 222 and guide posts 240; the number can be flexibly selected based on the actual situation.

[0099] In summary, the terminal device provided in this application embodiment allows the limiting buckle to engage with the housing via a mating groove, eliminating the need for intermediate components. This simplifies the number of fixing structural components for the buttons, thereby simplifying the installation and removal of the buttons. The mounting and dismounting grooves on the positioning post, along with the first and second slots communicating with them, provide a certain deformation space for the limiting buckle. This allows the limiting buckle to easily engage with the housing during button installation, and conversely, to easily disengage from the housing during button removal. The entire button installation and removal process is convenient, quick, simple, and efficient, allowing users to replace buttons themselves and facilitating after-sales maintenance. Since the buttons in the terminal device provided in this application embodiment do not require intermediate components for fixation and can be fixed to the housing through their own structure, intermediate components can be eliminated, enabling miniaturization or compactness of the terminal device and making its design more flexible.
