Description

Technical Field

[0001] This utility model relates to the field of push button switch technology, and more specifically, to a detachable push button structure and electronic device. Background Technology

[0002] With the continuous popularization and development of smart devices, electronic devices (such as video intercom indoor units) are becoming an important part of smart homes, and their user experience and ease of operation are becoming increasingly important. When designing electronic devices with physical buttons (such as video intercom indoor units), to meet users' needs for intuitive and quick operation, a series of control buttons are usually set on the device panel to realize functions such as intercom, door opening, and alarm activation. However, the traditional button structure design has many shortcomings, especially in terms of button cap removal and replacement, which brings many inconveniences to users and production assembly.

[0003] Currently, most electronic devices with physical buttons use an outward-mounted button cap assembly method. This structure requires disassembling the device casing to access the button caps and internal components such as the button circuit board before replacing or maintaining the buttons. This not only increases disassembly and assembly time but may also damage the device casing or internal components, increasing repair costs. At the same time, although some electronic devices attempt to design easy external button cap replacement, they usually use a "dead-end" snap-fit ​​fixing method, where the button cap is fixed to the casing by a planar fit. This means that the button cap needs to withstand large deformation forces during assembly and disassembly, posing a high risk of breakage and thus limiting its actual ease of disassembly and assembly and reliability.

[0004] From a user experience perspective, existing button structures are often too rigid or complex in their fixing methods, making it difficult to meet users' personalized needs and self-replacement requirements. When users encounter situations such as worn button markings or button damage caused by accidental operation, they cannot quickly and easily replace the buttons themselves and must seek professional intervention or send them back to the manufacturer for repair. This undoubtedly increases the user's operational burden and waiting time, reducing the device's practicality and user satisfaction.

[0005] Therefore, the existing button structure of electronic devices suffers from poor ease of disassembly and assembly, insufficient reliability, and difficulty in meeting users' self-replacement needs. There is an urgent need for an improved detachable button structure to improve the disassembly and assembly efficiency of the button structure and reduce the replacement risk. Utility Model Content

[0006] This invention provides a detachable button structure and electronic device to solve the problems of poor ease of disassembly and assembly, insufficient reliability, and difficulty in meeting users' self-replacement needs in the button structure of existing electronic devices.

[0007] To address the aforementioned problems, according to one aspect of this utility model, a detachable button structure is provided, comprising: a button cap and a mounting housing.

[0013] Furthermore, the detachable button structure also includes a button circuit board with a push-button switch. The button circuit board is fixedly mounted on the back of the mounting housing. The mounting housing also has an elastomer. The mounting housing has a through cavity penetrating the front and back of the mounting housing, with a portion of the elastomer located within the through cavity. The push-button switch is aligned with the through cavity. One end of the elastomer is fixedly connected to the mounting housing, while the other end is suspended, serving as an abutting end that abuts against the back of the button cap. The pivot and mounting groove are located on the front of the mounting housing. When the button cap is pressed, the button cap presses against the abutting end, which passes through the through cavity and contacts the push-button switch, thus achieving button control. When the button cap is not pressed, the abutting end provides elasticity to reset the button cap.

[0014] Furthermore, the detachable button structure also includes a threaded connector; the back of the mounting housing has a positioning post and a screw post, the button circuit board has a positioning hole and a mounting hole, a portion of the positioning post is inserted into the positioning hole and is limited to fit the inner wall of the positioning hole to fix the button circuit board; the mounting hole is aligned with the screw post, the threaded connector has an external thread, the screw post has an internal thread, the threaded connector passes through the mounting hole and enters the screw post, the external thread and the internal thread engage to fix it, so that the threaded connector fixes the button circuit board to the back of the mounting housing.

[0015] Furthermore, the elastomer is made of elastic material; the elastomer includes a cross rib, a boss and an elastic arm, one end of the elastic arm is fixedly set on the inner wall of the through cavity, and the other end of the elastic arm is an abutting end, the boss is set on the side of the abutting end facing the button cap; the cross rib is set on the side of the abutting end facing the push switch, and the cross rib is used to press the push switch; wherein, the elastic arm provides elasticity so that the boss is always in contact with the back of the button cap.

[0019] Applying the technical solution of this utility model, this utility model provides a detachable button structure, including: a button cap and a mounting housing. The button cap includes a button body, a claw, and a buckle. The claw and buckle are respectively spaced apart on the back of the button body, and the front of the button body is used for pressing. The mounting housing has a rotating shaft and an assembly groove, and the claw has a clamping groove. When the button cap is mounted on the mounting housing, the rotating shaft is limited and engaged with the inner wall of the clamping groove, and the buckle is engaged and fixed with the inner wall of the assembly groove. When the buckle is not engaged and fixed with the inner wall of the assembly groove, the claw can rotate relative to the rotating shaft, and the rotating shaft can move out of the clamping groove through the opening of the clamping groove.

[0020] This invention utilizes a combination of claws and buckles to allow for quick installation of keycaps. Manual installation allows the rotating shaft to engage with the inner wall of the clamping groove, while the buckle secures it to the inner wall of the mounting groove. To remove the keycap from the mounting housing, simply disengage the buckle from the inner wall of the mounting groove, rotate the claw relative to the rotating shaft, and finally disengage the clamping groove from the rotating shaft through the opening. This design, by providing the claws with a degree of freedom of rotation relative to the rotating shaft, avoids the inconvenience and potential damage risks associated with conventional direct snap-fit ​​methods. The claws and buckles are made of elastic materials with a certain degree of elastic deformation capability. Combined with the rotational freedom and the clamping groove design, this effectively reduces the stress on the claws and buckles during installation and removal. The reduced deformation significantly lowers the likelihood of breakage, enhancing the reliability and durability of the detachable button structure. Simultaneously, the simplified button cap design not only saves material costs but also effectively meets users' needs for self-replacement and personalization, improving the product's market competitiveness. This invention solves the problems of poor ease of disassembly and assembly, insufficient reliability, and difficulty in meeting users' self-replacement needs in existing electronic device button structures. This invention features a simple and low-cost structure, facilitating assembly and subsequent maintenance. It offers significant advantages in improving production efficiency, enhancing user experience, reducing costs, and increasing product usability. It is applicable not only to building security electronic products (e.g., indoor intercoms) but also to external electrical equipment such as switch panels, smart locks, alarms, and network devices involving physical buttons, making it suitable for large-scale promotion and use.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0041] like Figures 1 to 9 As shown, an embodiment of this utility model provides a detachable button structure, including: a button cap 10 and a mounting housing 20. The button cap 10 includes a button body 11, a claw 12, and a buckle 13. The claw 12 and the buckle 13 are respectively spaced apart on the back of the button body 11, and the front of the button body 11 is used for pressing. The mounting housing 20 has a rotating shaft 21 and an assembly groove 22. The claw 12 has a clamping groove 121. When the button cap 10 is mounted on the mounting housing 20, the rotating shaft 21 is limited to the inner wall of the clamping groove 121, and the buckle 13 is engaged with the inner wall of the assembly groove 22. When the buckle 13 is not engaged with the inner wall of the assembly groove 22, the claw 12 can rotate relative to the rotating shaft 21, and the rotating shaft 21 can move out of the clamping groove 121 through the opening of the clamping groove 121.

[0042] This invention, by setting the claw 12 and the buckle 13 to cooperate, allows for quick installation of the keycap 10 by manually installing it. This allows the rotating shaft 21 to engage with the inner wall of the clamping groove 121, and the buckle 13 to engage with the inner wall of the assembly groove 22. When removing the keycap 10 from the mounting housing 20, simply disengage the buckle 13 from the inner wall of the assembly groove 22, rotate the claw 12 relative to the rotating shaft 21, and finally disengage the clamping groove 121 from the rotating shaft 21 through the opening. This invention, by providing the claw 12 with a degree of freedom of rotation relative to the rotating shaft 21, avoids the inconvenience and potential damage risks associated with conventional direct clamping methods compared to existing methods. The claw 12 and the buckle 13 are made of elastic materials, possessing a certain degree of elastic deformation capability, which, combined with the rotational freedom and the design of the clamping groove 121, allows for quick removal of the keycap 10. This design effectively reduces the deformation of the claws 12 and buckles 13 during disassembly and assembly, thereby greatly reducing the possibility of breakage and enhancing the reliability and durability of the detachable button structure. Simultaneously, the simplified design of the button cap 10 not only saves material costs but also effectively meets users' needs for self-replacement and personalization, enhancing the product's market competitiveness. This invention solves the problems of poor ease of disassembly and assembly, insufficient reliability, and difficulty in meeting users' self-replacement needs in existing electronic device button structures. This invention features a simple and low-cost structure, facilitates assembly and subsequent maintenance, and has significant advantages in improving production efficiency, enhancing user experience, reducing costs, and improving product usability. It can be applied not only to building security electronic products (e.g., indoor intercoms) but also to external electrical equipment such as switch panels, smart locks, alarms, and network devices involving mechanical physical buttons, making it suitable for large-scale promotion and use.

[0043] like Figure 2 As shown, the direction perpendicular to the front of the button body 11 is the first direction, and the orientation of the opening of the clamping groove 121 is the second direction. The angle between the first direction and the second direction is A, where 0° < A < 90°.

[0044] The principle behind angle A is that it allows the claw 12 to be inserted and removed at an angle onto the mounting housing 20, thereby reducing resistance during installation and disassembly. This design allows users to easily replace the keycap 10 without applying excessive force, improving the convenience and safety of keycap installation and removal. Practical applications are mainly in environments where keys need frequent replacement or maintenance, such as electronic devices in public places or high-frequency home smart devices. By adjusting angle A, the installation and removal experience of the keycap 10 can be optimized according to specific application environments and needs.

[0045] like Figure 2, Figure 3 and Figure 4 As shown, the claw 12 includes a first cantilever 122 and a second cantilever 123, with a clamping groove 121 formed between the first cantilever 122 and the second cantilever 123; the rotating shaft 21 has a receiving cavity 23 around it, with the opening of the receiving cavity 23 facing a third direction; when the button cap 10 is mounted on the mounting housing 20, at least a portion of the first cantilever 122 extends into the receiving cavity 23 and engages with the rotating shaft 21 to fix the claw 12 in a third direction, and the buckle 13 engages and fixes with the inner wall of the mounting groove 22 to fix the buckle 13 in a third direction; when the buckle 13 is not engaged and fixed with the inner wall of the mounting groove 22, the claw 12 is disengaged from the rotating shaft 21 by rotating and pulling the claw 12.

[0046] Utilizing the elastic properties of the first cantilever 122 and the second cantilever 123, the clamping groove 121 can form a stable clamping force around the rotating shaft 21 of the mounting housing 20, while simultaneously releasing the rotating shaft 21 during disassembly, enabling quick assembly and disassembly of the keycap 10. A receiving cavity 23 is designed around the rotating shaft 21, with its opening facing a third direction. When the keycap 10 is fixed to the mounting housing 20, at least a portion of the first cantilever 122 extends into the receiving cavity 23, forming a limiting fit with the rotating shaft 21, ensuring the keycap 10 is firmly fixed in the third direction. Simultaneously, the latch 13 engages with the inner wall of the mounting groove 22, further enhancing the stability of the keycap 10. When the latch 13 is not engaged with the inner wall of the mounting groove 22, a simple rotation and pulling action can disengage the claw 12 from the rotating shaft 21, enabling convenient disassembly of the keycap 10. This design not only simplifies the assembly and disassembly process but also reduces damage to the keycap 10 during assembly and disassembly, extending its service life.

[0047] like Figure 2 As shown, the detachable button structure also includes reinforcing ribs 30, which are fixedly connected to the back of the button body 11 and the claw 12 to support the claw 12. There are at least two reinforcing ribs 30, one of which is connected to the first cantilever 122 to support the first cantilever 122, and the other is connected to the second cantilever 123 to support the second cantilever 123.

[0048] In the detachable button structure of this utility model, the addition of reinforcing ribs 30 plays a crucial supporting role. The support of the reinforcing ribs 30 improves the overall rigidity of the claw 12, reduces deformation of the claw 12 during pressing, thereby optimizing the button feel and providing a smoother pressing experience. The configuration of at least two reinforcing ribs 30 ensures the supporting effect of the claw 12 in different directions. One reinforcing rib 30 is connected to the first cantilever 122, and the other is connected to the second cantilever 123. This layout not only enhances the structural stability of the claw 12 but also ensures that the claw 12 can bear force evenly when pressing the button cap 10, avoiding damage caused by excessive local stress. The use of reinforcing ribs 30 not only improves the mechanical performance of the button cap 10 but also provides users with a more comfortable operating experience. The design of the reinforcing ribs 30 greatly improves the durability and smoothness of the button operation.

[0049] like Figure 2 As shown, the buckle 13 includes a base 131 and a snap-fit ​​part 132. One end of the base 131 is fixedly disposed on the back of the button body 11, and the snap-fit ​​part 132 is fixedly disposed on the other end of the base 131. The angle between the extension direction of the snap-fit ​​part 132 and the extension direction of the base 131 is B, where 0° < B < 90°.

[0050] By setting the angle B between the snap-fit ​​part 132 and the base 131, the snap-fit ​​13 can be easily snapped into place by the inclined guide when assembled into the mounting slot 22 of the mounting housing 20. During disassembly, the snap-fit ​​can be easily released by pulling in the inclined direction. This inclined design of the snap-fit ​​13 not only simplifies the installation and removal process of the keycap 10 but also reduces potential damage to the snap-fit ​​13 during operation, thereby extending the service life of the key structure. The inclined design of the snap-fit ​​13 also allows users to easily replace the keycap 10 even in confined spaces without the need for specialized tools, greatly improving equipment maintenance efficiency and user experience.

[0051] like Figure 2 , Figure 3 and Figure 4 As shown, the rotating shaft 21 is a cylindrical shaft. When the keycap 10 is mounted on the mounting housing 20, the rotating shaft 21 is interference-fitted with the opening of the clamping groove 121. The opening of the clamping groove 121 is rounded. And / or, the buckle 13 includes a base 131 and a snap-fit ​​part 132. One end of the base 131 is fixedly mounted on the back of the key body 11, and the snap-fit ​​part 132 is fixedly mounted on the other end of the base 131. At least a portion of the outer periphery of the snap-fit ​​part 132 and the connection between the snap-fit ​​part 132 and the base 131 are rounded.

[0052] The cylindrical shaft's shape allows it to form a good contact surface with the clamping groove 121 on the claw 12, providing stable support and limiting function when the keycap 10 is fixed to the mounting housing 20. The interference fit between the shaft 21 and the opening of the clamping groove 121 ensures the stability of the keycap 10 during normal use and reduces the risk of accidental detachment. The rounded corner design at the opening of the clamping groove 121, as well as the rounded corner treatment on the base 131 and the snap-fit ​​portion 132 of the buckle 13, are all designed to reduce stress concentration that may occur during installation and disassembly, thereby preventing breakage of the claw 12 and the buckle 13 and improving the reliability and durability of the key structure. Through these detailed designs, the installation and disassembly of the keycap 10 becomes smoother, reducing operational difficulty and maintenance costs. By optimizing the detailed design of the shaft 21 and the buckle 13, the detachable key structure of this utility model can better adapt to various usage environments and meet users' dual needs for convenient key replacement and equipment reliability.

[0053] like Figure 5 and Figure 8 As shown, the detachable button structure also includes a button circuit board 40, which has a push switch 41. The button circuit board 40 is fixedly mounted on the back of the mounting housing 20. The mounting housing 20 also has an elastic body 24. The mounting housing 20 has a through cavity 25 that penetrates the front and back of the mounting housing 20. A portion of the elastic body 24 is located in the through cavity 25, and the push switch 41 is aligned with the through cavity 25. One end of the elastic body 24 is fixedly connected to the mounting housing 20, and the other end is suspended. This end is the abutment end 241, which abuts against the back of the button cap 10. The rotating shaft 21 and the mounting groove 22 are located on the front of the mounting housing 20. When the button cap 10 is pressed, the button cap 10 presses the abutment end 241, and the abutment end 241 passes through the through cavity 25 and contacts the push switch 41 to realize button control. When the button cap 10 is not pressed, the abutment end 241 provides elastic force to reset the button cap 10.

[0054] The precise control of the button function is achieved through the cooperation of the button circuit board 40 and the push switch 41. The button circuit board 40 is fixedly mounted on the back of the mounting housing 20, which is also equipped with an elastomer 24. A portion of the elastomer 24 is located within the through cavity 25, and the push switch 41 is aligned with the through cavity 25 to ensure accurate transmission of the button signal. One end of the elastomer 24 is fixedly connected to the mounting housing 20, while the other end is a suspended abutment end 241. This design allows the abutment end 241 to maintain contact with the back of the button cap 10, so that when the button cap 10 is pressed, it can immediately respond and trigger the push switch 41 to realize the button function. When the button cap 10 is not pressed, the elasticity provided by the abutment end 241 helps the button cap 10 to reset, ensuring the continuity of button operation and real-time feedback.

[0055] Through the ingenious cooperation between the button circuit board 40 and the elastomer 24, the detachable button structure of this invention enables rapid response and accurate control, enhancing the user experience. By optimizing the cooperation between the button circuit board 40 and the elastomer 24, the detachable button structure of this invention can meet the stringent requirements of professional-grade equipment for button operation, improving equipment reliability and user satisfaction.

[0056] like Figure 6 , Figure 7 and Figure 8 As shown, the detachable button structure also includes a threaded connector 50; the back of the mounting housing 20 has a positioning post 26 and a screw post 27, the button circuit board 40 has a positioning hole 42 and a mounting hole 43, a part of the positioning post 26 is inserted into the positioning hole 42 and is limited to the inner wall of the positioning hole 42 to fix the button circuit board 40; the mounting hole 43 is aligned with the screw post 27, the threaded connector 50 has an external thread, the screw post 27 has an internal thread, the threaded connector 50 passes through the mounting hole 43 and enters the screw post 27, the external thread and the internal thread are screwed together to fix it, so that the threaded connector 50 fixes the button circuit board 40 on the back of the mounting housing 20.

[0057] The threaded connector 50, in conjunction with the positioning post 26 and screw post 27 on the back of the mounting housing 20, securely fixes the button circuit board 40. The positioning post 26 inserts into the positioning hole 42 on the button circuit board 40, engaging with the inner wall of the positioning hole 42 to ensure accurate positioning of the button circuit board 40 on the mounting housing 20, preventing displacement of the circuit board during operation and ensuring accurate transmission of button signals. The mounting hole 43 aligns with the screw post 27, and the threaded connector 50 passes through the mounting hole 43 and enters the screw post 27. The engagement of the external and internal threads provides additional support for the button circuit board 40 and ensures a tight connection between the circuit board and the mounting housing 20.

[0058] With the use of threaded connectors 50 (e.g., screws or bolts), the button circuit board 40 can be firmly fixed to the mounting housing 20, maintaining stable operation even under high-intensity use environments and reducing the risk of the circuit board loosening or falling off. The main application scenarios are in equipment requiring long-term stable operation, such as control terminals of industrial automated production lines and operation panels of security systems. By employing the fixing method of threaded connectors 50, the detachable button structure of this invention can meet the high requirements of these devices for the stability and reliability of the button circuit board 40, ensuring the normal operation of the equipment.

[0059] like Figure 5 and Figure 7As shown, the elastomer 24 is made of elastic material; the elastomer 24 includes a cross rib 242, a boss 243 and an elastic arm 244. One end of the elastic arm 244 is fixedly disposed on the inner wall of the through cavity 25, and the other end of the elastic arm 244 is an abutment end 241. The boss 243 is disposed on the side of the abutment end 241 facing the button cap 10; the cross rib 242 is disposed on the side of the abutment end 241 facing the push switch 41, and the cross rib 242 is used to press the push switch 41; wherein, the elastic arm 244 provides elastic force so that the boss 243 is always in contact with the back of the button cap 10.

[0060] Through structural optimization of the elastomer 24, good feedback and automatic reset functions are achieved for the button cap 10 during pressing. One end of the elastic arm 244 is fixed to the inner wall of the through cavity 25, and the other end is the abutment end 241, which maintains contact with the back of the button cap 10. The boss 243 is located on the side of the abutment end 241 facing the button cap 10, which can provide stable support force, avoid the wobbling of the button cap 10 when not pressed, and improve the accuracy of operation. The cross rib 242 is located on the side of the abutment end 241 facing the press switch 41. When the button cap 10 is pressed, the cross rib 242 can directly act on the press switch 41 to trigger the button function. The elasticity of the elastic arm 244 ensures that the abutment end 241 can always maintain contact with the back of the button cap 10, and can provide stable elasticity even after the button cap 10 has been used for a long time, ensuring the automatic reset of the button and a good feel.

[0061] By optimizing the structure of the elastomer 24, the detachable button structure of this invention not only improves the button's response speed and feedback effect but also extends the button structure's lifespan and reduces maintenance costs. Through optimized structural design of the elastomer 24, the detachable button structure of this invention provides users with a more comfortable and durable button operation experience, meeting the high-performance requirements of modern devices for button functionality.

[0062] Specifically, a functional group is formed by a claw 12 and a latch 13, and there are at least two functional groups. The at least two functional groups are spaced apart on the button body 11. There are multiple rotating shafts 21, and at least a portion of the multiple rotating shafts 21 are matched with the multiple functional groups one by one. There are multiple mounting slots 22, and at least a portion of the multiple mounting slots 22 are matched with the multiple functional groups one by one. And / or, there are multiple button caps 10, and the multiple button caps 10 are spaced apart on the mounting housing 20.

[0063] Through the coordinated operation of multiple functional groups, the keycap 10 is stably fixed on the mounting housing 20 while retaining its convenient disassembly and assembly characteristics. The number of pivots 21 and mounting slots 22 matches the number of functional groups, ensuring that each functional group can form an effective connection with the corresponding component on the mounting housing 20. Through the rational configuration of the functional groups, the detachable key structure of this invention can withstand greater pressing force, while maintaining the structural integrity of the keycap 10 during disassembly and assembly, reducing damage to the keycap 10 during these operations. By optimizing the configuration of the functional groups, the detachable key structure of this invention can meet the high precision and high reliability requirements of these devices for key operation, providing users with a more professional and comfortable operating experience.

[0064] It should be noted that the keycap 10 and the mounting housing 20 constitute the core components of this utility model. The keycap 10 includes a key body 11, a claw 12, and a latch 13. The claw 12 and the latch 13 are respectively and spaced apart on the back of the key body 11, while the front of the key body 11 is used for pressing operation. The claw 12 and the latch 13 are made of elastic material. This design allows for necessary elastic deformation during installation and disassembly, thereby avoiding damage that may be caused by rigid connections. The mounting housing 20 is equipped with a pivot 21 and a mounting groove 22, and the claw 12 is designed with a clamping groove 121. When the keycap 10 is fixed to the mounting housing 20, the pivot 21 and the inner wall of the clamping groove 121 engage in a limiting fit, ensuring the stability of the keycap 10; at the same time, the latch 13 engages and fixes with the inner wall of the mounting groove 22, further enhancing the stability of the connection. When the buckle 13 is not locked to the inner wall of the assembly groove 22, the claw 12 can rotate relative to the rotating shaft 21. This feature allows the rotating shaft 21 to be moved out through the opening of the clamping groove 121, thereby realizing the convenient disassembly and assembly of the button cap 10 without the need for tools, which greatly improves maintenance efficiency and user experience.

[0065] like Figure 9 As shown, this utility model also provides an electronic device, which includes the above-mentioned detachable button structure; the electronic device also includes a device body and a screen assembly 60, the screen assembly 60 is fixedly disposed on the front of the device body for displaying information; the mounting housing 20 is fixedly disposed on the front of the device body, and the button cap 10 is located on the front of the device body for button operation.

[0066] By integrating a highly efficient detachable button structure, the electronic device achieves a significant improvement in ease of operation and maintenance efficiency. The electronic device also includes a main body and a screen assembly 60. The screen assembly 60 is fixedly mounted on the front of the main body and is used to display information such as visitor images and call status. The mounting housing 20 is fixedly mounted on the front of the main body, while the button caps 10 are located on the front of the main body for easy button operation by the user, such as answering, hanging up, and door lock control.

[0067] By integrating a detachable button structure, the electronic device's operating interface becomes more flexible. Users can easily replace the button caps 10 according to their personal preferences or usage scenarios, enhancing the device's personalization capabilities and user experience. Practical applications are primarily in entrance control systems for residential communities, commercial buildings, hospitals, and other locations. Through optimized structural design, this electronic device not only possesses efficient information display and communication functions but also meets diverse user needs for the device's operating interface, improving its practicality and market competitiveness.

[0068] like Figure 9 As shown, the electronic device also includes a lens lever 70 and a camera 80. The camera 80 is disposed on the front of the main body of the device and is used to acquire image information. The lens lever 70 is disposed on the mounting housing 20 and is electrically connected to the camera 80. The lens lever 70 is used to adjust the camera 80. And / or, there are multiple button caps 10, which are spaced apart on the mounting housing 20. The front of the multiple button caps 10 has different marking patterns, and the marking patterns correspond to different functions of the electronic device.

[0069] The lens lever 70 is electrically connected to the camera 80, enabling flexible adjustment of the camera 80 to meet the requirements of shooting angle and field of view in different usage scenarios. The camera 80 is set on the front of the main body of the device and is used to collect image information, such as facial images of visitors. The lens lever 70 is set on the mounting housing 20 and electrically connected to the camera 80. Users can easily adjust the angle and focal length of the camera 80 by operating the lens lever 70 to obtain the best shooting effect.

[0070] With the configuration of the lens lever 70 and the camera 80, the video communication function of the electronic device is significantly enhanced. Users can adjust the parameters of the camera 80 at any time according to actual needs, ensuring high-quality and flexible video communication. The main application scenarios are in places requiring high-definition video communication, such as residences and business centers. By optimizing the configuration of the lens lever 70 and the camera 80, the electronic device of this invention can provide users with a clearer and smoother video communication experience, meeting the high standards of modern communication technology for high-quality video communication.

[0071] It should be noted that, as Figure 2 As shown, in a specific embodiment of this utility model, the two claws 12 on the keycap 10 and the two "live buckles" (i.e., buckles 13) on the pressing side are respectively engaged and fixed with the rotating shaft 21 and the mounting groove 22 on the mounting housing 20. Since the pressing side of the keycap 10 uses two "live buckles", it can be easily disassembled and assembled. At the same time, the first cantilever 122 of the claw 12 on the keycap 10 is a relatively long cantilever, which has a certain elastic deformation capability. The rotating shaft 21 that cooperates with it has a design with cut edges on both sides. During the disassembly and assembly of the keycap 10, the interference between the claw 12 and the rotating shaft 21 can be effectively reduced, thereby reducing the risk of breakage of the claw 12. In addition, the opening of the clamping groove 121 of the claw 12 on the keycap 10 has a certain angle, so that during the disassembly process, the "live buckles" on the pressing side of the keycap 10 can be pried out first. Then, with the support of the side wall of the mounting housing 20, the claw 12 on the keycap 10 can be disengaged from the rotating shaft 21, thereby achieving quick disassembly.

[0072] The specific working process and principle of one embodiment of this utility model will now be described in detail as follows:

[0073] This utility model proposes a detachable button structure that can be used in electronic devices (e.g., video intercom indoor units), such as... Figure 9 As shown, the electronic device mainly includes a screen assembly 60, a lens lever 70, a mounting housing 20, a camera 80, and four button caps 10; the four button caps 10 have identical structures, and different function icons can be printed on their surfaces; such as Figure 6 As shown, each button cap 10 on the front of the mounting housing 20 has a corresponding mating elastic body 24, a pivot 21, and a mounting groove 22 in its assembly position area; as shown Figure 7 As shown, the back (i.e., the inner area) of the mounting housing 20 has positioning posts 26 and screw posts 27, and each elastic body 24 has a cross rib 242; the elastic body 24 has a two-section cantilever structure, which ensures both its strength and improves its elasticity; the specific structure of the button cap 10 is as follows. Figure 2 As shown, the left side of the button cap 10 has two symmetrical claws 12. The first direction is perpendicular to the front of the button body 11, and the second direction is the orientation of the opening of the clamping groove 121. The angle between the first and second directions is A (i.e., the opening direction of the clamping groove 121 on the claw 12 forms an angle A with the vertical plane). The first cantilever 122 of the claw 12 is a relatively long cantilever with a certain elastic deformation capability; for example... Figure 2As shown, there are two symmetrically arranged clips 13 on the right side of the button cap 10. Each clip 13 includes a base 131 and a snap-fit ​​part 132. One end of the base 131 is fixedly disposed on the back of the button body 11, and the snap-fit ​​part 132 is fixedly disposed on the other end of the base 131. The angle between the extension direction of the snap-fit ​​part 132 and the extension direction of the base 131 is B. This design makes it easier to snap and disassemble in this area.

[0074] The detachable button structure proposed in this utility model is very convenient to install in electronic devices; for example... Figure 1 , Figure 7 and Figure 8 As shown, firstly, using the two positioning posts 26 of the mounting housing 20 for positioning, the button circuit board 40 is installed onto the back of the mounting housing 20, and then fixed to the corresponding screw posts 27 on the mounting housing 20 using four screws (i.e., threaded connectors 50); then, as... Figure 1 As shown, the left-side clip 12 of the keycap 10 is obliquely pushed into the corresponding pivot 21 of the mounting housing 20, and rotated along the pivot 21. Simultaneously, the right-side clip 13 of the keycap 10 is pressed into the corresponding mounting slot 22 of the mounting housing 20, thus completing the quick installation of the keycap 10, resulting in the desired appearance. Figure 3 The final assembly state is shown. The remaining button caps 10 can be installed in the same way.

[0075] The implementation method of the pressing and reset function of button cap 10 is as follows: Figure 3 and Figure 5 As shown, the right end (i.e., the abutting end 241) of the elastic body 24 of the mounting housing 20 has a boss 243. The boss 243 and the back of the keycap 10 are slightly interference-fitted (i.e., always maintain a certain elastic support). This can prevent the keycap 10 from slightly collapsing in a static state and reduce the force-bearing area when pressed, thus ensuring the key feel. Therefore, when the keycap 10 is pressed, the keycap 10 will move downward in a "seesaw" manner around the pivot 21, overcoming the elastic force of the elastic body 24, so that the cross rib 242 on it will touch the push switch 41 on the key circuit board 40 to achieve press control. When the keycap 10 is released, it will rebound to its original position by the elastic force of the elastic body 24.

[0076] Similarly, the disassembly process of the detachable button structure for electronic devices proposed in this utility model is also very convenient; as follows: Figure 4As shown, manually pry up the right side of the keycap 10 to disengage the clip 13 on the keycap 10 from the mounting groove 22 on the mounting housing 20. Then, using the left side wall of the mounting housing 20 as support, rotate and disengage the claw 12 on the keycap 10 from the pivot 21 on the mounting housing 20. Since the clip 13 on the keycap 10 and the mounting groove 22 on the mounting housing 20 are engaged by a bevel, disassembly is very easy. In addition, the claw 12 on the keycap 10 is deformable, and the pivot 21 on the mounting housing 20 has beveled edges on both sides. The circular shaft design effectively reduces the interference required when the claw 12 and the pivot 21 disengage. Therefore, the claw 12 and the pivot 21 can be easily disassembled, which not only greatly reduces the risk of breakage during the process, but also improves the human-computer interaction experience. Due to the ease of disassembly and assembly and the reliability of the button cap 10, coupled with the fact that each button cap 10 has the same structure, the material reusability is high, saving development costs. Moreover, users can customize and replace the function icons on the surface as needed to meet their expansion needs, which to a certain extent improves the practicality and competitiveness of the product.

[0077] In summary, this utility model, by setting the claw 12 and the buckle 13 to cooperate, allows for the quick installation of the keycap 10 by manually installing it. This allows the rotating shaft 21 to engage with the inner wall of the clamping groove 121, and the buckle 13 to engage with the inner wall of the assembly groove 22. When removing the keycap 10 from the mounting housing 20, simply disengage the buckle 13 from the inner wall of the assembly groove 22, rotate the claw 12 relative to the rotating shaft 21, and finally disengage the clamping groove 121 from the rotating shaft 21 through the opening. This allows for quick removal of the keycap 10. By providing the claw 12 with a degree of freedom of rotation relative to the rotating shaft 21, this utility model avoids the inconvenience and potential damage risks associated with traditional snap-fit ​​fixing methods compared to conventional methods. Furthermore, the claw 12 and the buckle 13 are made of elastic materials, possessing a certain degree of elastic deformation capability, which, combined with the rotational freedom and the clamping groove 12... The design of button 10 effectively reduces the deformation of the claws 12 and buckles 13 during disassembly and assembly, thereby greatly reducing the possibility of breakage and enhancing the reliability and durability of the detachable button structure. Simultaneously, the simplified design of the button cap 10 not only saves material costs but also effectively meets the needs of users for self-replacement and personalization, enhancing the product's market competitiveness. This invention solves the problems of poor disassembly and assembly convenience, insufficient reliability, and difficulty in meeting user replacement needs in the button structures of existing electronic devices. This invention features a simple and low-cost structure, facilitates assembly and subsequent maintenance, and has significant advantages in improving production efficiency, enhancing user experience, reducing costs, and improving product usability. It can be applied not only to building security electronic products (e.g., indoor intercoms) but also to external electrical equipment such as switch panels, smart locks, alarms, and network devices involving mechanical physical buttons, making it suitable for large-scale promotion and use.
