Since the two keys are similar in appearance and layout, it is difficult for users to accurately identify the specific function of each key when quickly operating, which not only affects the efficiency of operation, but also increases the risk of misoperation. CONTENT OF THE UTILITY MODEL

[0004] The purpose of the present application is to provide a double-key switch that effectively solves the problem of unclear function division of existing double-key switches by differentiating the principles of the two keys and using different movement methods, thereby reducing the risk of misoperation by users when operating. Another purpose of the present application is to provide an electronic device.

[0005] To achieve the above-mentioned purpose, the present application provides a double-key switch, comprising:

[0006] A fixed component provided with a first trigger area and a second trigger area;

[0007] A first key component comprising a first key in sliding connection with the fixed component, the first key being capable of moving relative to the fixed component when pressed;

[0008] A second key component comprising a second key in rotational connection with the fixed component, the second key being capable of rotating relative to the fixed component when pressed.

[0009] In some embodiments, the first key component further comprises a first elastic member that drives the first key to move in a direction away from the first trigger area.

[0010] In some embodiments, the second key component further comprises a second elastic member that drives the second key to move in a direction away from the second trigger area.

[0013] In some embodiments, the second key is provided with a first notch, and the first key is located in the first notch; and / or,

[0014] The distal end of the first key is higher than the distal end of the second key in terms of the fixed assembly; and / or,

[0015] Either one of the first key and the fixed assembly is provided with a guide sliding groove, and the other one of the first key and the fixed assembly is provided with a guide sliding block in sliding connection with the guide sliding groove; and / or,

[0016] Either one of the second key and the fixed assembly is provided with a guide recess, and the other one of the second key and the fixed assembly is provided with a guide convex point in rotational connection with the guide recess.

[0017] In some embodiments, the fixed assembly comprises:

[0018] A cavity shell, which is internally provided with the first key assembly and the second key assembly;

[0019] A key circuit board, which is provided with the first trigger area and the second trigger area.

[0020] In some embodiments, the fixed assembly further comprises a sealing member, which is in sealing connection with the cavity shell.

[0021] In some embodiments, the sealing member is provided with a second key limiting structure, which limits the position of the second key in a direction away from the second trigger area;

[0022] The cavity shell is provided with a first key limiting structure, which limits the position of the first key in a direction away from the first trigger area.

[0023] In some embodiments, the fixed assembly further comprises a key support, which is in fixed connection with the cavity shell, the key support is in foolproof cooperation with the key circuit board, and the key circuit board is located on a side of the key support away from the cavity shell.

[0024] The application further provides an electronic device comprising a shell and the double-key switch.

[0025] With respect to the above background, the double button switch provided by the present application mainly comprises a fixed assembly, a first button assembly and a second button assembly. The fixed assembly is provided with a first trigger area and a second trigger area. The first button assembly comprises a first button in sliding connection with the fixed assembly. The first button can move relative to the fixed assembly when pressed. The second button assembly comprises a second button in rotational connection with the fixed assembly. The second button can rotate relative to the fixed assembly when pressed.

[0026] In the field of electronic devices, especially in portable handheld devices, users often need to quickly perform various operations through physical buttons. However, a major technical problem faced by existing double button switch designs is that the function division is not clear, because the two buttons are similar in appearance and layout, making it difficult for users to accurately identify the specific function of each button when quickly operating. This design not only affects the efficiency of operation, but also increases the risk of misoperation.

[0027] To solve this problem, the present application provides a double button switch that realizes clear division of functions by differentiating the principles and movement modes of the two buttons. Specifically, the double button switch comprises a fixed assembly, a first button assembly and a second button assembly. The fixed assembly is provided with a first trigger area and a second trigger area for triggering different functions respectively. The first button assembly comprises a first button in sliding connection with the fixed assembly. The button can move relative to the fixed assembly when pressed. This sliding connection design allows users to activate the function of the first trigger area through linear pressing action.

[0028] In contrast, the second button assembly comprises a second button in rotational connection with the fixed assembly. The button can rotate relative to the fixed assembly when pressed. This rotational connection design allows users to activate the function of the second trigger area through rotational action. Through this differentiated movement mode, users can intuitively identify and activate different functions through the movement form (sliding or rotating) of the buttons.

[0029] This design not only avoids confusion due to similar appearance and layout of the buttons, but also improves the accuracy and efficiency of user operation. Even in emergency or quick operation situations, users can quickly identify and operate the correct button through different movement modes, thereby reducing the risk of misoperation. Therefore, the above-mentioned double button switch differentiates the principles of the two buttons in different movement modes, effectively solving the problem of unclear function division of existing double button switches, thereby reducing the risk of misoperation by users when operating.

[0030] In combination with the above structure and process, it can be seen that the double-key switch has at least the following beneficial effects: the double-key switch effectively solves the problem of unclear function division of the existing double-key switch by differentiating two key principles and in different movement modes, thereby reducing the risk of user misoperation during operation.

[0054] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without any creative work fall within the scope of protection of the present application.

[0055] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0056] Please refer to Figure 1 and Figure 2 , Figure 1 the schematic diagram of the double-key switch and the electronic device provided by the embodiments of the present application, Figure 2 the cross-sectional view of the double-key switch and the electronic device provided by the embodiments of the present application.

[0057] In the first specific embodiment, the double-key switch provided by the embodiments of the present application mainly comprises a fixed component 1, a first key component 2 and a second key component 3.

[0058] In addition to serving as the installation basis of the first key component 2 and the second key component 3, the fixed component 1 is provided with a first trigger area 1001 and a second trigger area 1002, which play the trigger function of the switch under the force of the first key component 2 and the second key component 3.

[0059] It should be noted that the triggering function referred to here is not limited to the triggering ability caused by direct contact with the circuit switch, but also includes the triggering ability caused by contact with the triggering structure (which can be the fixed assembly 1 itself) and then contact with the circuit switch through the triggering structure, so the fixed assembly 1 is not limited to including the circuit switch such as the circuit board and the switching device thereon, but can also not include the circuit switch, and still be able to achieve the triggering function of the double-key switch.

[0060] In this embodiment, the first key assembly 2 includes a first key 202 that is slidingly connected to the fixed assembly 1, and the first key 202 can produce movement relative to the fixed assembly 1 when pressed. The second key assembly 3 includes a second key 302 that is rotationally connected to the fixed assembly 1, and the second key 302 can produce rotation relative to the fixed assembly 1 when pressed.

[0061] In the field of electronic devices, especially in portable handheld devices, users often need to quickly perform various operations through physical keys. However, a major technical problem faced by existing double-key switch designs is the lack of clear function division, as the two keys are similar in appearance and layout, making it difficult for users to accurately identify the specific function of each key when quickly operating. This design not only affects the efficiency of operation, but also increases the risk of misoperation.

[0062] To solve this problem, the present application provides a double-key switch that achieves clear division of functions by differentiating the principles and movement methods of the two keys. Specifically, the double-key switch includes a fixed assembly 1, a first key assembly 2, and a second key assembly 3. The fixed assembly 1 is provided with a first triggering area 1001 and a second triggering area 1002 for triggering different functions, respectively. The first key assembly 2 includes a first key 202 that is slidingly connected to the fixed assembly 1, and the key can produce movement relative to the fixed assembly 1 when pressed. This sliding connection design allows users to activate the function of the first triggering area 1001 through linear pressing action.

[0063] In contrast, the second key assembly 3 includes a second key 302 that is rotationally connected to the fixed assembly 1, and the key can produce rotation relative to the fixed assembly 1 when pressed. This rotational connection design allows users to activate the function of the second triggering area 1002 through rotational action. Through this differentiated movement method, users can intuitively identify and activate different functions through the movement form (sliding or rotating) of the keys.

[0064] The design not only avoids confusion caused by similar appearance and layout of the keys, but also improves the accuracy and efficiency of user operation. Even in an emergency or quick operation, the user can quickly identify and operate the correct key through different movement methods, thereby reducing the risk of misoperation. Therefore, the above-mentioned double-key switch effectively solves the problem of unclear function division of the existing double-key switch by differentiating the principles of the two keys and using different movement methods, thereby reducing the risk of misoperation by the user during operation.

[0065] In combination with the above structure and process description, it can be seen that the double-key switch has at least the following beneficial effects: the double-key switch effectively solves the problem of unclear function division of the existing double-key switch by differentiating the principles of the two keys and using different movement methods, thereby reducing the risk of misoperation by the user during operation.

[0066] In some embodiments, the first key assembly 2 includes a first elastic member 201 and a first key 202 slidingly connected with the fixed assembly 1. The first key 202 can move relative to the fixed assembly 1 when pressed, and the first elastic member 201 drives the first key 202 to move away from the first trigger area 1001.

[0067] In this embodiment, the first key assembly 2 is designed to be slidingly connected with the fixed assembly 1, so that the first key 202 can produce relative movement when pressed, and the first elastic member 201 ensures that the first key 202 can reset away from the first trigger area 1001 after release, while providing adaptive resistance during the pressing operation of the first key 202. This design allows the user to activate the function of the first trigger area 1001 through a sliding action, improving the feedback effect and rebound strength when pressed.

[0068] In some embodiments, the second key assembly 3 includes a second elastic member 301 and a second key 302 rotatably connected with the fixed assembly 1. The second key 302 can rotate relative to the fixed assembly 1 when pressed, and the second elastic member 301 drives the second key 302 to move away from the second trigger area 1002.

[0069] In this embodiment, the second key assembly 3 is designed to be rotatably connected with the fixed assembly 1, so that the second key 302 can produce relative rotation when pressed, and the second elastic member 301 ensures that the second key 302 can reset away from the second trigger area 1002 after release, while providing adaptive resistance during the pressing operation of the second key 302. This design allows the user to activate the function of the second trigger area 1002 through a rotating action, improving the feedback effect and rebound strength when pressed.

[0070] Please refer to Figure 3 and Figure 4 ,Figure 3 A schematic diagram of a double-key switch provided by an embodiment of the present application, Figure 4 A sectional view of a double-key switch provided by an embodiment of the present application.

[0071] In some embodiments, the first key assembly 2 is provided with a notch 4, and the second key assembly 3 is located in the notch 4; or,

[0072] The second key assembly 3 is provided with a notch 4, and the first key assembly 2 is located in the notch 4.

[0073] In this embodiment, a design of a double-key switch is provided, in which the first key assembly 2 and the second key assembly 3 are integrated and designed compactly through a specific spatial layout. Specifically, there are two cases: one is that the first key assembly 2 is provided with a notch 4, allowing the second key assembly 3 to be located in this notch 4; the other case is that the second key assembly 3 is provided with a notch 4, and the first key assembly 2 is located in this notch 4.

[0074] This design allows the two key assemblies to be optimally configured in space, whether the first key assembly 2 contains the second key assembly 3 or the second key assembly 3 contains the first key assembly 2, to achieve a compact layout between the components. The design of the notch 4 can be diverse, which can be a cavity completely inside one component, or an opening at the edge of the component. Such a design can not only ensure the independence of the two key assemblies during operation, but also reduce the occupied space of the overall design, improve the portability and aesthetics of the device.

[0075] Regardless of the inclusion relationship, whether the first component completely wraps the second component or partially wraps it, an effective space utilization scheme can be provided while maintaining the intuitiveness and convenience of key operation. This design also allows different spatial relationships between the key assemblies, such as nesting and surrounding, increasing the flexibility and diversity of the design to adapt to different devices and user needs.

[0076] Please refer to Figure 5 , Figure 5 A schematic diagram of a second key provided by an embodiment of the present application.

[0077] In some embodiments, the second key 302 is provided with a first notch 401, and the first key 202 is located in the first notch 401.

[0078] In this embodiment, a specific layout of a double-key switch is particularly described, in which the second key 302 is designed with a specific structure - a first notch 401. For example, the first notch 401 is located at the upper middle position of the second key 302, which serves to accommodate the first key 202, so that the first key 202 can be located in this first notch 401. Figure 5 ​

[0079] This design allows the first button 202 and the second button 302 to have some overlap in the vertical direction, but maintains a proper gap in the circumferential direction perpendicular to the vertical direction, ensuring that they do not interfere with each other during operation. Specifically, when the user presses the first button 202, the first button 202 can move within its free space, triggering the associated switch function, without affecting the state of the second button 302. Similarly, when the user operates the second button 302, the second button 302 can rotate around its fulcrum, realizing its switch function, without causing any interference to the first button 202.

[0080] Such a layout design not only saves space, but also improves the operation efficiency and user experience of the double-button switch. Each button maintains the ability to operate independently, while reducing the possibility of misoperation, as the triggering mechanism and movement of each button are independent. This design also helps to improve the compactness and portability of the device, while maintaining good operation feel and feedback.

[0081] In some embodiments, the distal end height of the first button 202 is higher than the distal end height of the second button 302, based on the fixed assembly 1.

[0082] In this embodiment, the two buttons on the fixed assembly 1, the first button 202 and the second button 302, have a clear height difference in design, which is reflected in the distal end part that is convenient for the user to press with the fingers. Specifically, the distal end height of the first button 202 is designed to be higher than the distal end height of the second button 302, which makes it easier for the user to distinguish between the two buttons when operating.

[0083] This height difference design not only helps the user to quickly identify the two different buttons visually, but also in actual operation, the user can distinguish which button is higher through the tactile feeling of the fingers, so as to determine the corresponding function. For example, the user can quickly locate and operate the first button 202 by finding the higher distal end part, while the lower distal end part guides the user to operate the second button 302. This intuitive identification method improves the accuracy and efficiency of operation, especially when quick response or operation in inconvenient visual conditions is required.

[0084] In some cases, in addition to the height difference, the first button 202 and the second button 302 also consider ergonomic principles, by adjusting the height and shape of the buttons, so that the user's fingers can more naturally adapt to the position and shape of the buttons, providing a more comfortable pressing experience.

[0085] In particular, the surfaces of the first button 202 and the second button 302 are designed with concave-convex changes, which not only increases the visual recognition obviousness, but also improves the user operation accuracy through tactile feedback.

[0086] Please refer to Figure 6 , Figure 6 Partially exploded view of the double-key switch and the electronic device provided by the embodiments of the present application.

[0087] In some embodiments, either the first button 202 or the fixed assembly 1 is provided with a guide sliding groove 5, and the other is provided with a guide sliding block 6 connected with the guide sliding groove 5.

[0088] In this embodiment, in order to ensure that the first button 202 can smoothly and accurately slide on the fixed assembly 1, a pair of sliding mechanisms, namely the guide sliding groove 5 and the guide sliding block 6, are specially designed. This sliding mechanism has two possible setting modes, both of which aim to improve the accuracy and reliability of the operation of the first button 202, and ensure that it can move smoothly when pressed to trigger the corresponding function.

[0089] The first setting mode is to set the guide sliding block 6 on the first button 202, and set the guide sliding groove 5 on the fixed assembly 1. In this configuration, when the first button 202 is pressed, the guide sliding block 6 slides along the guide sliding groove 5, thereby ensuring that the movement of the first button 202 is both smooth and stable.

[0090] The second setting mode is to set the guide sliding block 6 on the fixed assembly 1, and set the guide sliding groove 5 on the first button 202. In this configuration, the guide sliding groove 5 on the first button 202 guides the guide sliding block 6 on the fixed assembly 1 to slide, also achieving smooth operation of the first button 202.

[0091] Regardless of which setting mode is adopted, the combination of the guide sliding groove 5 and the guide sliding block 6 provides precise guidance for the first button 202, so that the user can get better feel and feedback when operating. This design not only improves the comfort and accuracy of operation, but also helps to prolong the service life of the button and reduce wear caused by improper operation or excessive friction.

[0092] In some embodiments, either the second button 302 or the fixed assembly 1 is provided with a guide recess 7, and the other is provided with a guide protrusion 8 connected with the guide recess 7.

[0093] In this embodiment, to ensure that the second button 302 can rotate accurately and smoothly around the fixed shaft, a pair of rotating mechanisms, namely the guide groove 7 and the guide protrusion 8, are specially designed. There are two possible settings for this rotating mechanism, both aiming to improve the accuracy and reliability of the operation of the second button 302, ensuring that it can move smoothly and stably when rotated to trigger the corresponding function.

[0094] The first setting is to set the guide protrusion 8 on the second button 302 and the guide groove 7 on the fixed assembly 1. In this configuration, when the second button 302 is rotated, the guide protrusion 8 rotates along the guide groove 7, ensuring that the rotation of the second button 302 is both smooth and stable.

[0095] The second setting is to set the guide protrusion 8 on the fixed assembly 1 and the guide groove 7 on the second button 302. In this configuration, the guide protrusion 8 on the fixed assembly 1 is inserted into the guide groove 7 on the second button 302, also achieving the smooth rotation of the second button 302.

[0096] Regardless of which setting is adopted, the combination of the guide groove 7 and the guide protrusion 8 provides accurate guidance for the second button 302, allowing users to have a better feel and feedback when operating. This design not only improves the comfort and accuracy of operation, but also helps to prolong the service life of the button, reducing wear and tear caused by improper operation or excessive friction.

[0097] In some embodiments, the fixed assembly 1 includes:

[0098] The cavity shell 101 has a first button assembly 2 and a second button assembly 3 inside;

[0099] The button circuit board 102 has a first trigger area 1001 and a second trigger area 1002.

[0100] In this embodiment, the fixed assembly 1 is composed of the cavity shell 101 and the button circuit board 102, and these two parts together constitute the structural basis of the double-button switch. The cavity shell 101 is an internal space specially designed to accommodate the first button assembly 2 and the second button assembly 3, providing physical support and protection for these two button assemblies. This design allows the button assemblies to be stably installed in the fixed assembly 1, ensuring the accuracy and reliability of the operation.

[0101] The key circuit board 102 is another key part of the fixed assembly 1, which is provided with a first trigger area 1001 and a second trigger area 1002. These trigger areas are specific positions on the circuit board, corresponding to the first key 202 and the second key 302, for detecting whether the keys are pressed or triggered. When the user operates the first key 202 or the second key 302, the corresponding trigger area 1001 or 1002 can sense the action of the key and transmit a signal to the electronic device for corresponding processing.

[0102] By combining the cavity shell 101 and the key circuit board 102 together, the fixed assembly 1 not only provides a compact and integrated mounting platform for the dual-key switch, but also ensures the accuracy of key operation and the accurate transmission of electronic signals. This structural design helps to improve the overall performance and durability of the dual-key switch, while also making the internal layout of the electronic device more compact and orderly.

[0103] As an option, guide sliders 6 and guide grooves 7 are provided on the inner walls of the cavity shell 101, which can be symmetrically arranged on both sides of the inner walls of the cavity shell 101; correspondingly, a guide slot 5 is provided on the first key 202, and a guide protrusion 8 is provided on the second key 302, which can also be symmetrically arranged on the outer walls of the first key 202 and the second key 302, respectively.

[0104] When the first key 202 and the second key 302 are installed inside the cavity shell 101, the guide slot 5 on the first key 202 cooperates with the guide slider 6 on the inner wall of the cavity shell 101 to form a sliding connection; at the same time, the guide protrusion 8 on the second key 302 cooperates with the guide groove 7 on the inner wall of the cavity shell 101 to form a rotating connection. This installation method allows the first key 202 to perform smooth sliding operations inside the cavity shell 101, while the second key 302 can rotate around the guide protrusion 8 in the guide groove 7, thereby triggering the corresponding functions.

[0105] Please refer to Figure 7 , Figure 7 The sealing member provided in the embodiments of the present application.

[0106] In some embodiments, the fixed assembly 1 further includes a sealing member 103, which is in sealing connection with the cavity shell 101.

[0107] In this embodiment, the fixed assembly 1 is particularly designed to include a sealing member 103, which functions to seal and isolate the cavity shell 101 and its internal components, the first key assembly 2 and the second key assembly 3. Through the sealing connection with the cavity shell 101, the sealing member 103 ensures the sealing separation between the entire assembly and the key circuit board 102, thereby providing a sealed and waterproof effect.

[0108] Since the sealing member 103 is located between the key circuit board 102 and the cavity shell 101, it not only needs to ensure the sealing effect, but also needs to ensure the normal realization of the switch function. In order to achieve this purpose, the sealing member 103 is designed to be directly subjected to the force of the first key assembly 2 and the second key assembly 3, and to transmit these forces to the first trigger area 1001 and the second trigger area 1002 on the key circuit board 102. In this way, the sealing member 103 not only plays a sealing role, but also serves as an intermediate medium for force transmission.

[0109] Through this design, even in harsh environmental conditions such as humid or underwater environments, the double-key switch can maintain its function and prevent moisture from entering the key circuit board 102, thereby protecting the electronic device from damage. At the same time, due to the transmission effect of the sealing member 103, the pressing action of the user when operating the first key 202 and the second key 302 can be accurately transmitted to the trigger area on the key circuit board 102, ensuring the stability and reliability of the switch function. This design improves the durability and applicability of the double-key switch, allowing it to work normally in various environments.

[0110] As an option, the sealing member 103 is provided with a first elastic structure and a second elastic structure, the first key assembly 2 can press the first elastic structure on the first side of the first elastic structure, so that the second side of the first elastic structure contacts the first trigger area 1001 of the key circuit board 102; the second key assembly 3 can press the second elastic structure on the first side of the second elastic structure, so that the second side of the second elastic structure contacts the second trigger area 1002 of the key circuit board 102.

[0111] As an option, the first side of the first key 202 serves as a pressing surface, and the second side of the first key 202 is provided with a first connecting rod, the end of the first connecting rod can press the first elastic structure on the first side of the first elastic structure; the first side of the second key 302 serves as a pressing surface, and the second side of the second key 302 is provided with a second connecting rod, the end of the second connecting rod can press the second elastic structure on the first side of the second elastic structure.

[0112] As an option, the first elastic member 201 and the second elastic member 301 are springs, the springs are sleeved on the corresponding connecting rods, the first end of the spring abuts against the second side of the corresponding key, and the second end of the spring abuts against the first side of the sealing member 103.

[0113] In some embodiments, the second key limiting structure 9 limits the position of the second key 302 in the direction away from the second trigger area 1002;

[0114] The first key limiting structure 10 limits the position of the first key 202 in the direction away from the first trigger area 1001.

[0115] In this embodiment, the second key limiting structure 9 and the first key limiting structure 10 respectively limit the positions of the second key 302 and the first key 202. Specifically, the second key limiting structure 9 is located in the direction away from the second trigger area 1002 of the second key 302, which prevents the second key 302 from moving excessively or deviating from its predetermined position during operation. This design ensures that the second key 302 can move stably within a limited range during rotation, avoiding structural damage or functional failure caused by excessive rotation, thereby improving the reliability and durability of the double key switch.

[0116] Similarly, the first key limiting structure 10 is located in the direction away from the first trigger area 1001 of the first key 202. By limiting the maximum movement distance of the first key 202, it ensures that the first key 202 can remain within the predetermined stroke range during sliding. This limiting design not only prevents the first key 202 from deviating from the fixed assembly 1 due to excessive pressing during operation, but also ensures the stability and consistency of key operation, further enhancing user operation experience. Through this limiting mechanism, the first key 202 and the second key 302 can not interfere with each other during their respective operations, while ensuring the overall functionality and stability of the double key switch.

[0117] In some cases, the sealing member 103 is provided with the second key limiting structure 9, and the second key 302 is in contact with the second key limiting structure 9 under the force of the second elastic member 301;

[0118] The cavity shell 101 is provided with the first key limiting structure 10, and the first key 202 is in contact with the first key limiting structure 10 under the force of the first elastic member 201.

[0119] In this embodiment, the sealing member 103 is specially designed with the second key limiting structure 9, while the cavity shell 101 is designed with the first key limiting structure 10. The setting of these two limiting structures is crucial for the stability and durability of the double key switch.

[0120] The main function of the second key limiting structure 9 is to limit the maximum rotation position of the second key 302, i.e., the outermost position it can rotate to. Under the force of the second elastic member 301, the second key 302 will be in contact with the second key limiting structure 9, which prevents the second key 302 from rotating excessively, thereby avoiding possible structural damage or functional failure.

[0121] Similarly, the first key limiting structure 10 serves to limit the maximum movement position of the first key 202, i.e., the outermost position it can move to. Under the force of the first elastic member 201, the first key 202 will come into contact with the first key limiting structure 10, which prevents the first key 202 from moving excessively and ensures that it always stays within the predetermined stroke during operation.

[0122] With this design, the limiting structure not only improves the operational safety of the double-key switch but also enhances the stability of its structure. They ensure that the keys do not deviate from the predetermined movement trajectory during operation, thereby avoiding possible damage and misoperation.

[0123] As an option, the second key limiting structure 9 is a set of symmetrically arranged semicircular protrusions on the sealing member 103, and the first key limiting structure 10 is a stopper extending towards the distal end of the first key 202 on the cavity shell 101.

[0124] Please refer to Figure 8 , Figure 8 Split diagrams of the double-key switch and electronic device provided by the embodiments of the present application.

[0125] In some embodiments, the fixed assembly 1 further includes a key bracket 104, which is fixedly connected with the cavity shell 101, and the key bracket 104 is foolproofly matched with the key circuit board 102, which is located on the side of the key bracket 104 away from the cavity shell 101.

[0126] In this embodiment, the design of the fixed assembly 1 further includes a key bracket 104, which forms a fixed connection with the cavity shell 101. The key bracket 104 serves to provide support for the key circuit board 102 and is foolproofly matched with the key circuit board 102, meaning that the key circuit board 102 can be installed on the key bracket 104 in a unique way, thereby preventing the possibility of installation errors.

[0127] Specifically, the key bracket 104 is located on the side away from the cavity shell 101, which layout allows the key circuit board 102 to be stably installed on the key bracket 104, while also ensuring the proper spacing and correct positional relationship between the key circuit board 102 and the cavity shell 101 and its internal components (such as the first key assembly 2 and the second key assembly 3). This design not only guarantees the stability and safety of the key circuit board 102 but also helps to improve the assembly efficiency and accuracy of the entire double-key switch.

[0128] By using the key bracket 104, the overall structure of the fixed assembly 1 is strengthened, and the installation process of the key circuit board 102 is also simplified. This design makes the fixed assembly 1 more stable and can withstand more physical pressure and wear and tear in daily use, thereby improving the durability and reliability of the double-key switch. In addition, due to the sealing and waterproof effect of the sealing member 103, water can be prevented from entering the key circuit board 102 on the second side of the key bracket 104 through the sealing member 103 on the first side of the key bracket 104, further enhancing the protection performance of the electronic device.

[0129] As an option, a connecting column is provided on the peripheral side of the cavity shell 101, and the key bracket 104 is connected to the connecting column of the cavity shell 101 through the fastener 11, realizing the fixed connection of the key bracket 104 and the cavity shell 101; after the key circuit board 102 is prevented from being matched with the key bracket 104, it is fixedly connected through the fastener 11.

[0130] In particular, the key bracket 104 is provided with a via hole, and the number and position of the via hole correspond to the first elastic structure and the second elastic structure on the sealing member 103, so that the first elastic structure and the second elastic structure correspondingly pass through the via hole and contact the key circuit board 102.

[0131] In some cases, the fastener 11 adopts a screw.

[0132] The application also provides an electronic device comprising a shell 12 and the above-mentioned double-key switch.

[0133] The electronic device should have all the beneficial technical effects of the above-mentioned double-key switch, which will not be repeated here.

[0134] In some embodiments, the cavity shell 101 is integrally formed with the shell 12, and the cavity shell 101 is located inside the shell 12. The first key assembly 2 and the second key assembly 3 are exposed from the outer surface of the shell 12 after being installed in the cavity shell 101. Under the action of the sealing member 103 and the key bracket 104, the cavity shell 101 and the first key assembly 2 and the second key assembly 3 therein are sealed and separated from other positions inside the shell 12; the key circuit board 102 is fixed on the side of the key bracket 104 away from the cavity shell 101, and the key circuit board 102 is located inside the shell 12 and is sealed and separated from the cavity shell 101, effectively forming waterproof for the key circuit board 102.

[0135] As an option, the electronic device is an infrared or visible light handheld device, and the key function of the double-key switch can be any combination of focusing, shooting and ranging, such as focusing and shooting, focusing and ranging, ranging and shooting, etc., without limiting the specific function of the double-key switch.

[0136] In one specific embodiment, the installation process of the shell 12 and the double-key switch in the electronic device is described as follows.

[0137] During installation, the first key 202 is guided into a specific position along the guide slot 5, and then the first elastic member 201 is placed. The second key 302 is installed in a fulcrum rotating manner. The second key 302 is provided with arc-shaped guide protrusions 8 at the corners on both sides, and the shell 12 is provided with arc-shaped guide grooves 7. During installation, the guide protrusions 8 of the second key 302 are placed into the guide grooves 7, so as to reach a specific position, and then the second elastic member 301 is placed. After the first key 202, the second key 302, and the corresponding elastic members are installed in place, the sealing member 103 is installed. The sealing member 103 is provided with two semicircular protrusions, which are in contact with and interfere with the second key 302. When the key bracket 104 is installed, the key bracket 104 is fixed on the shell 12 by the fastener 11, and the sealing member 103 is appropriately compressed. The second key 302 generates a fulcrum between the shell 12 and the sealing member 103, so that the second key 302 can only rotate around the fulcrum. The first key 202 and the second key 302 are different in principle and will not interfere in structure. The appropriate compression between the sealing member 103 and the shell 12 makes the first key 202, the second key 302, the elastic member, and other devices outside the shell 12, and the key circuit board 102 inside the shell 12, effectively forming a waterproof function. The key circuit board 102 and the key bracket 104 are fixed by the fastener 11. The protrusions are arranged on the surface of the key bracket 104 in an asymmetric position, and the key circuit board 102 is formed into a foolproof design. The first key 202 and the second key 302 are close to each other in the shell 12, similar to a trigger type operation, and the user operation is more portable.
