Detailed Implementation

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0039] The terms "first," "second," and "third" in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movements between components in a specific orientation (as shown in the figures). If the specific orientation changes, the directional indications also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0040] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0041] In existing cantilever button designs, a common approach is to use skirts around the button cap and internal openings in the structural components. The button cap is secured to the internal components via the skirts, and the cantilever is typically located on the outer edge of the skirts, occupying significant space. Furthermore, the central area of ​​the structural component is hollowed out, preventing direct mounting of the button plate and requiring an additional external structure to accommodate it, resulting in low overall space utilization. To achieve button indicator functions (such as LED lighting effects), additional light guide plates or light guide pillars are needed, further increasing assembly complexity and cost.

[0042] Based on this, this application provides a button assembly and an electronic device; the button assembly reduces the lateral space occupied by the button assembly and does not require additional light guide structure, effectively improving space utilization.

[0043] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] See Figures 1-5 , Figure 1 This is a schematic diagram of the structure of a button assembly provided in one embodiment of this application; Figure 2 for Figure 1 The button assembly shown is a cross-sectional view along line AA. Figure 3 for Figure 2 A magnified view of a section at point A in the middle; Figure 4 for Figure 1 The diagram shows the structure after removing the button caps and button plate. Figure 5 for Figure 2 A schematic diagram of the button panel. This application provides a button assembly 100, which can be used to control the on or off of an electronic device; such as Figure 2 As shown, the button assembly 100 may include a fixed shell 1, a button cantilever 2, a button cap 3, and a button plate 4.

[0045] The fixed housing 1 serves as a support structure to support the button assembly 100. Specifically, the fixed housing 1 has a top wall 11 and an annular side wall 12 connected to the top wall 11, and the top wall 11 and the annular side wall 12 of the fixed housing 1 form a receiving space. The outer surface of the top wall 11 of the fixed housing 1 has a receiving groove 111 for receiving the button cap 3. The bottom wall of the receiving groove 111 has a through hole 1111, and the receiving groove 111 communicates with the receiving space through the through hole 1111. Preferably, the through hole 1111 can be coaxially arranged with the receiving groove 111.

[0046] Combination Figure 2 and Figure 4 The button cantilever 2 is disposed within the through hole 1111. Specifically, the button cantilever 2 may include a fixing part 21 and an elastic part 22; wherein, the fixing part 21 is used to fix the button cap 3, and the elastic part 22 is used to provide elastic support so that the button cantilever 2 can reciprocate along the axial direction Z of the through hole 1111. One end of the elastic part 22 is connected to the fixing part 21, and the other end is connected to the side wall of the through hole 1111, so that the button cantilever 2 and the fixing shell 1 can be integrally formed, which enhances the connection stability between the button cantilever 2 and the fixing shell 1 and avoids the loosening problem of traditional buckle or screw fixing.

[0047] Continue reading Figure 2 The button cap 3 is at least partially disposed within the receiving groove 111 and fixedly connected to the fixing part 21, so that when the button cap 3 is pressed, it can drive the fixing part 21 to move away from the receiving groove 111. Specifically, the shape of the button cap 3 matches the shape of the receiving groove 111, and the size of the button cap 3 is slightly smaller than the size of the receiving groove 111, so as to facilitate the up and down movement of the button cap 3 and avoid friction between the side wall of the button cap 3 and the side wall of the receiving groove 111.

[0048] The button plate 4 is disposed within the fixed housing 1. The button plate 4 includes a switch 41 corresponding to the button cap 3. Squeezing the button cap 3 can trigger the switch 41. Specifically, the button cap 3, the button cantilever 2, and the switch 41 are all correspondingly disposed. When the button cap 3 is squeezed, the fixing part 21 causes the elastic part 22 to deform, thereby triggering the switch 41.

[0049] The diameter of the through hole 1111 is smaller than the diameter of the bottom wall of the receiving groove 111, so that the bottom wall of the receiving groove 111 forms a limiting structure to prevent the button cap 3 from being excessively squeezed, which could damage the button cantilever 2.

[0050] Thus, by providing a through hole 1111 on the bottom wall of the receiving groove 111 of the fixed shell 1, and directly placing the button cantilever 2 inside the through hole 1111 and connecting it to the side wall of the through hole 1111 using the elastic part 22, while placing the button plate 4 inside the fixed shell 1 and setting the switch 41 of the button plate 4 to correspond with the button cap 3, the switch 41 can be triggered when the button cap 3 is squeezed, thereby reducing the lateral space occupied by the button assembly 100 and effectively improving the space utilization rate.

[0051] See Figure 3 In a specific embodiment, the button cap 3 may further include a body portion 31 disposed within the receiving groove 111 and a protrusion 32 disposed on the side of the body portion 31 facing the button cantilever 2. The protrusion 32 is fixedly connected to the fixing portion 21, and the body portion 31 is spaced apart from the bottom wall of the receiving groove 111 to allow for travel space of the button cap 3, so that the button cap 3 can move in the direction of the switch 41 when squeezed.

[0052] Specifically, the body part 31 is used to withstand compression. The protrusion 32 extends a certain distance from the side surface of the body part 31 near the button cantilever 2 along the axial direction Z of the through hole 1111 towards the through hole 1111, and is fixedly connected to the fixing part 21 of the button cantilever 2, so that the body part 31 can be spaced apart from the bottom wall of the receiving groove 111.

[0053] Specifically, the distance d between the main body 31 and the bottom wall of the receiving groove 111 can be 1 mm; wherein, the distance d between the main body 31 and the bottom wall of the receiving groove 111 can also be any value among 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, and 0.9 mm.

[0054] The connection between the protrusion 32 and the fixing part 21 can be mechanical or adhesive. For example, a slot 51 can be provided on the protrusion 32 to engage with the fixing part 21, or the parts can be bonded with glue.

[0055] See Figure 4 The button cantilever 2 has two elastic portions 22. The two elastic portions 22 are respectively disposed on opposite sides of the fixed portion 21, so that the force distribution of the button cantilever 2 is more uniform when pressed, reducing the risk of deformation caused by local stress concentration. In addition, the structure of double elastic portions 22 provides stronger restoring force while enhancing structural stability and avoiding failure of the elastic portion 22 due to single-point force.

[0056] Specifically, such as Figure 4As shown, the first ends 221 of the two elastic parts 22 are respectively disposed on opposite sides of the fixing part 21 along the first direction X and connected to the sidewall of the through hole 1111; the second ends 222 of the two elastic parts 22 are respectively disposed on opposite sides of the fixing part 21 along the second direction Y and connected to the fixing part 21; wherein, the first direction X and the second direction Y are intersected, and both the first direction X and the second direction Y are perpendicular to the axial direction Z of the through hole 1111.

[0057] In other words, on one side of the fixing part 21, the first end 221 of each elastic part 22 is connected to the sidewall of the through hole 1111 along the first direction X, and the second end 222 is connected to the fixing part 21 along the second direction Y. By placing the two ends of each elastic part 22 in different directions of the fixing part 21, the length of the elastic part 22 is extended as much as possible in a limited space, thereby enhancing the elasticity of the elastic part 22 and making it easier for the button cap 3 to trigger the switch 41 when squeezed. Specifically, the portion between the first end and the second end of the elastic part 22 can be straight or curved.

[0058] Preferably, the first direction and the second direction can be perpendicular to each other.

[0059] Combination Figure 3 and Figure 4 In a specific embodiment, the fixing part 21 has multiple positioning holes 211, and the button cap 3 has multiple positioning posts 33; the multiple positioning posts 33 are embedded in the multiple positioning holes 211, so as to fix the button cap 3 on the fixing part 21 while realizing the positioning function.

[0060] Specifically, multiple positioning holes 211 can be provided on the circumferential periphery of the fixing part 21 and are equally spaced along the circumferential direction of the fixing part 21; correspondingly, multiple positioning posts 33 can be provided on the circumferential periphery of the protrusion 32 of the button cap 3 and are equally spaced along the circumferential direction.

[0061] In a specific embodiment, the positioning post 33 can be a thermoplastic post; a thermoplastic post is a columnar structure that achieves its fixing function by deforming after heating. Specifically, the thermoplastic post can be made of thermoplastic materials such as polypropylene or polyethylene. During assembly, after the thermoplastic post is embedded in the positioning hole 211, the positioning post 33 can be thermoplasticized by means of hot air, thereby fixing the button cap 3 to the fixing part 21. Each positioning hole 211 penetrates the fixing part 21 along the axial direction Z of the through hole 1111, and the corresponding thermoplastic post is embedded in the positioning hole 211 and protrudes from the side of the fixing part 21 away from the button cap 3, so as to better fix the button cap 3.

[0062] It is understandable that using a hot-melt column fixing method can significantly improve the connection strength between the button cap 3 and the fixing part 21, avoiding loosening caused by vibration or fatigue. The hot-melt process eliminates the need for additional adhesives or fasteners, simplifying the assembly process and reducing material costs. The connection formed by material welding has higher sealing performance, effectively preventing dust and moisture intrusion. The hot-melt process offers good controllability, allowing precise control of deformation to ensure installation accuracy, while avoiding stress concentration problems that may occur with traditional mechanical fixing.

[0063] Of course, in other embodiments, the mating relationship between the positioning hole 211 and the positioning post 33 can also be achieved by means of interference fit, snap-fit ​​structure or threaded connection.

[0064] like Figure 3 As shown, in a specific embodiment, the button arm 2 may further include a contact 23 disposed on the side surface of the fixing portion 21 away from the button cap 3, for triggering the switch 41. Specifically, the contact 23 protrudes from the side surface of the fixing portion 21 away from the button cap 3 and extends along the axial direction Z of the through hole 1111 in a direction away from the button cap 3, so that when the button arm 2 is squeezed and moves toward the switch 41, the contact 23 can trigger the switch 41.

[0065] Specifically, the height of the contact 23 can be greater than the height of the part of the positioning post 33 that protrudes from the fixing part 21, so that the contact 23 can contact the switch 41.

[0066] Of course, in some other embodiments, the contact 23 can also be disposed on the button cap 3. Specifically, in one embodiment, the button cap 3 has a contact 23 on the surface near the button arm 2; the button arm 2 has a through hole, the contact 23 passes through the through hole and protrudes from the surface of the fixing part 21 away from the button cap 3, so as to trigger the switch 41. Specifically, the contact 23 can be disposed on the surface of the protrusion 32 facing the fixing part 21; the through hole can be disposed on the fixing part 21 and located in the center of the fixing part 21 to avoid the positioning hole 211.

[0067] Alternatively, in another specific embodiment, the button cap 3 has a contact 23 on the side surface near the button cantilever 2; there is a gap between the button cantilever 2 and the side wall of the through hole 1111, the contact 23 passes through the gap and protrudes from the side surface of the fixing part 21 away from the button cap 3, so as to trigger the switch 41. Specifically, the contact 23 can be provided on the side surface of the body part 31 facing the fixing part 21; the fixing part 21 forms a gap with the side wall of the through hole 1111.

[0068] It is understandable that, compared to setting the contact 23 on the button cap 3, this embodiment directly sets the contact 23 on the button cantilever 2, which can also reduce the alignment action during assembly and effectively reduce the difficulty of the process.

[0069] See Figure 2 In a specific embodiment, the inner surface of the top wall 11 of the fixed shell 1 has a fixing post 13 disposed around the through hole 1111; and the key plate 4 is fixed to the end of the fixing post 13 away from the top wall 11, so that the key plate 4 is directly disposed on the fixed shell 1, avoiding the need to set a structure to accommodate the key plate 4 outside the key, and effectively improving the space utilization of the overall structure.

[0070] Specifically, one end of the fixing post 13 is connected to the top wall 11 of the fixing shell 1, and the other end extends away from the button cap 3 along the axial direction of the through hole 1111. The fixing posts 13 are evenly distributed or partially arranged around the through hole 1111, and their structure can be cylindrical, square, or irregularly shaped. The connection between the button plate 4 and the fixing post 13 can be a snap-fit ​​structure, a threaded connection, or an adhesive bonding method.

[0071] In this embodiment, the button plate 4 and the fixing post 13 are fixed by a threaded connection. Specifically, the fixing post 13 can be a hollow threaded post with threads on its inner wall surface.

[0072] In a specific embodiment, the number of fixing posts 13 can be two; the two fixing posts 13 are disposed on the bottom wall of the receiving groove 111 and are respectively located on opposite sides of the through hole 1111, so as to better fix the keypad 4 and avoid tilting and shifting of the keypad 4 due to single-point fixing.

[0073] Combination Figure 2 and Figure 5 The button plate 4 has two fixing holes 43 corresponding to the fixing post 13, for inserting bolts and connecting with the fixing post 13 by threads. The switch 41 is disposed between the two fixing holes 43 so that the button cap 3 or the button cantilever can be triggered during the up and down movement of the switch 41.

[0074] Combination Figure 2 and Figure 5 In a specific embodiment, the top wall 11 of the fixed shell 1 may further include a light-transmitting area 112 located on one side of the receiving groove 111; the keypad 4 includes a light-emitting element 42 corresponding to the light-transmitting area 112. The switch 41 is electrically connected to the light-emitting element 42 and controls the light-emitting element 42 to emit light. The light emitted by the light-emitting element 42 can pass through the light-transmitting area 112, providing intuitive visual feedback during key operation and enhancing the user's interactive experience. The switch 41, as a control unit, can be implemented through a touch module on the circuit board or a mechanical button. When the keycap 3 is pressed, the switch 41 is activated, causing the light-emitting element 42 to emit light.

[0075] Furthermore, by coordinating the light-emitting element 42 with the light-transmitting area 112, and allowing the light emitted by the light-emitting element 42 to directly pass through the light-transmitting area 112, the button assembly 100 can achieve its indicating function without the need for additional light guide structures, thereby further reducing assembly complexity and effectively lowering manufacturing costs.

[0076] Among them, such as Figure 1 As shown, the light-transmitting area 112 can be arranged around the circumferential periphery of the receiving groove 111; specifically, the light-transmitting area 112 can be an annular light-transmitting area 112, so as to form an annular light-emitting area on the outer surface of the top wall 11 when the light-emitting element 42 emits light.

[0077] Alternatively, in some embodiments, the light-transmitting area 112 may also include multiple independent sub-areas, which may be spaced apart around the circumferential periphery of the receiving groove 111 to form multiple independent light-emitting areas on the outer surface of the top wall 11 when the light-emitting element 42 emits light.

[0078] Alternatively, in other embodiments, the light-transmitting area 112 may also be a patterned light-transmitting area 112, so as to form a special light-emitting area on the outer surface of the top wall 11 when the light-emitting element 42 emits light.

[0079] Specifically, the fixing shell 1 can be made of transparent material, and its outer surface is coated with paint. During the manufacturing process, the paint on the circumferential periphery of the receiving groove 111 can be removed by laser engraving to form a light-transmitting area 112.

[0080] like Figure 5 As shown, the button panel 4 has multiple light-emitting elements 42; the multiple light-emitting elements 42 are arranged at intervals around the circumferential periphery of the switch 41 and are located on the side surface of the button panel 4 facing the light-transmitting area 112, so as to achieve the effect of the button with a ring-shaped ambient light in a limited space.

[0081] This application provides a button assembly 100, which includes a fixed housing 1, a button cantilever 2, a button cap 3, and a button plate 4. The fixed housing 1 has a top wall 11 and an annular side wall 12. The outer surface of the top wall 11 of the fixed housing 1 has a receiving groove 111. The bottom wall of the receiving groove 111 has a through hole 1111. The button cantilever 2 is disposed within the through hole 1111. The button cantilever 2 includes a fixing part 21 and an elastic part 22. One end of the elastic part 22 is connected to the fixing part 21, and the other end is connected to the side wall of the through hole 1111. The button cap 3 is at least partially disposed within the receiving groove 111 and fixedly connected to the fixing part 21. The button plate 4 is disposed within the fixed housing 1. The button plate 4 includes a switch 41 corresponding to the button cap 3. Squeezing the button cap 3 can trigger the switch 41. By providing a through hole 1111 on the bottom wall of the receiving groove 111 of the fixed shell 1, and directly placing the button cantilever 2 inside the through hole 1111 and connecting it to the side wall of the through hole 1111 using the elastic part 22, and placing the button plate 4 inside the fixed shell 1, and setting the switch 41 of the button plate 4 to correspond to the button cap 3, the switch 41 can be triggered when the button cap 3 is squeezed, thereby reducing the lateral space occupied by the button assembly 100 and effectively improving the space utilization rate.

[0082] See Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application; Figure 7 for Figure 6 A schematic diagram of the cooperation between the card slot and the card holder. This application provides an electronic device, which can be a story machine. The electronic device includes a device body 200 and a button assembly 100; wherein, the device body 200 includes a housing 5, which serves as a support structure for the device body 200 and is used to house other structural components such as a battery assembly; the button assembly 100 is disposed on the outer surface of the housing 5, and the switch 41 in the button assembly 100 is electrically connected to the battery assembly for controlling the opening and closing of the electronic device; the button assembly 100 can be any of the button assemblies involved in the above embodiments.

[0083] Combination Figure 2 and Figure 7 In a specific embodiment, the housing 5 has a slot 51, and the end of the annular sidewall 12 of the button assembly 100 away from the top wall 11 has a locking portion 121; the locking portion 121 is inserted into the slot 51 to fix the button assembly 100 to the housing 5. Through the mechanical engagement structure of the slot 51 and the locking portion 121, quick installation and secure fixing of the button assembly 100 to the housing 5 can be achieved, effectively preventing loosening due to vibration or external force during use. The locking portion 121 extends from the end surface of the annular sidewall 12 away from the top wall 11 along the axial direction Z in a direction away from the top wall 11.
