Description

Technical Field

[0001] This utility model relates to the field of helmet communication equipment technology, and in particular to a helmet Bluetooth walkie-talkie and helmet device. Background Technology

[0002] A helmet-mounted Bluetooth walkie-talkie is a wireless communication device designed specifically for riding scenarios such as motorcycles and electric bikes. Its core purpose is to allow riders to communicate safely and conveniently while focusing on the road, such as enabling riders to talk to each other, answer phone calls, listen to navigation and music.

[0003] In existing technologies, helmet-mounted Bluetooth walkie-talkies include a main unit and an earpiece. The main unit typically contains the main control circuitry, battery, and Bluetooth module, while the earpiece (including a speaker and microphone) is fixedly installed inside the helmet. The main unit and earpiece are connected via an audio cable for audio signal transmission and power supply.

[0004] However, before each helmet use, users must manually and accurately insert the audio cable into the main unit's interface. When removing the helmet, users easily forget to unplug the audio cable. At this time, the main unit, usually secured to the side of the helmet by clips or buckles, has its own weight, and the pulling force of the audio cable can easily yank it off its mounting, causing it to fall to the ground. This can not only cause physical damage such as broken casing and shattered screen, but may also cause the delicate internal electronic components to malfunction due to the impact, resulting in financial loss and inconvenience for the user. Utility Model Content

[0005] This application provides a helmet Bluetooth walkie-talkie and helmet device to solve the problems in the prior art, such as cumbersome operation and easy forgetting to unplug the wires, which can cause the device to fall.

The base is provided with a first electrical connector; the main unit is detachably connected to the base and includes a control component and a second electrical connector electrically connected to the control component. The audio component is installed on the helmet and electrically connected to the first electrical connector; when the main unit is installed on the base, the first electrical connector and the second electrical connector are in contact and conductive, and the audio component is signal-connected to the control component through the first electrical connector and the second electrical connector.

[0007] In some embodiments, a power source is also included, the power source being electrically connected to the first electrical connector; When the first electrical connector and the second electrical connector are connected, a circuit is formed in which the power source supplies power to the control component.

[0008] In some embodiments, both the first electrical connector and the second electrical connector are spring pin connectors.

[0009] In some embodiments, the base further includes a housing assembly and a connecting mechanism. The power supply, the first electrical connector, and the connecting mechanism are all disposed on the housing assembly. The connecting mechanism includes a first latching member, a second latching member, a reset member, and a lever that are linked together. The host includes a housing assembly, and the control assembly and the second electrical connector are both mounted on the housing assembly. The outer surface of the housing assembly is provided with a first engaging portion and a second engaging portion. In the locked state, the reset member drives the first latching member and the second latching member to move closer to each other and latch onto the first engaging part and the second engaging part respectively; In the open state, operating the lever drives the first latching member and the second latching member to move away from each other, thereby releasing them from the engagement with the first and second engaging portions.

[0010] In some embodiments, the first snap-fit ​​member includes a first snap-fit ​​portion and a first force-receiving portion connected to each other, and the second snap-fit ​​member includes a second snap-fit ​​portion and a second force-receiving portion connected to each other; The lever is rotatably connected to the base and includes a first drive unit, a second drive unit, and an operating unit connected thereto. When the operating part is operated, the first driving part acts on the first force receiving part, and the second driving part acts on the second force receiving part, causing the first locking part and the second locking part to move away from each other.

[0011] In some embodiments, the housing assembly is provided with a receiving cavity and a first opening, a second opening, and an operating port communicating with the receiving cavity, and the cavity wall of the receiving cavity is formed with a guide structure; The first force-receiving part and the second force-receiving part are placed inside the receiving cavity and can move along the guide structure; The first latching portion extends outward through the first opening, the second latching portion extends outward through the second opening, and at least a portion of the operating portion extends outward through the operating port for operation.

[0012] In some embodiments, the operating part has a first sleeve portion protruding on the side opposite to the first force-receiving part and the second force-receiving part, and the cavity wall of the receiving cavity has a corresponding second sleeve portion protruding. The reset component is a compression spring, which is sleeved on the first sleeve portion and the second sleeve portion. The two ends of the compression spring are respectively connected to the operating portion and the cavity wall of the receiving cavity.

[0013] In some embodiments, the first force-receiving part and the second force-receiving part are disposed opposite to each other and form an assembly space between them. The reset member is a tension spring, which is disposed in the assembly space and its two ends are respectively connected to the first force-receiving part and the second force-receiving part.

[0014] In some embodiments, the base is provided with a first magnetic attraction element, and the main unit is provided with a second magnetic attraction element; when the main unit is close to the base, the first magnetic attraction element and the second magnetic attraction element attract each other.

[0015] Secondly, embodiments of this application also provide a helmet device, including: Helmet; and As described above, the helmet Bluetooth walkie-talkie is detachably mounted on the helmet.

[0016] Based on the above embodiments, when the main unit is installed on the base, the first electrical connector and the second electrical connector make contact and conduct. When the first electrical connector and the second electrical connector are connected, the audio component is signal-connected to the control component through this connection link. Thus, during the disassembly of the main unit and the base, since the audio cable plug remains connected to the signal connection port of the base, there is no need to disconnect the audio cable. This not only avoids problems such as interface wear and poor contact that may be caused by frequent plugging and unplugging of the audio cable, but also effectively extends the service life of the audio cable and related interfaces, greatly facilitating the installation and disassembly of the main unit and the base.

[0025] This application provides a helmet device comprising a helmet and a helmet Bluetooth intercom 1 detachably mounted on the helmet. The helmet Bluetooth intercom 1 provides cyclists with various functions, such as communication between riders, making and receiving phone calls, playing music, and obtaining GPS navigation information.

[0026] Please see Figures 1 to 3 The helmet Bluetooth walkie-talkie 1 includes a base 10, a main unit 20, and an audio component. The base 10 may be equipped with a clamp, which, through its interaction with a specific structure on the helmet, securely and easily fixes the base 10 to the helmet, ensuring installation stability and ease of operation. The main unit 20 is detachably mounted on the base 10, allowing users to easily install, remove, or replace it according to their needs. The audio component is located inside the helmet and connects to the main unit 20 for signal transmission. This audio component may include a speaker and a microphone. The speaker outputs sound, allowing the rider to clearly hear conversations, music, or navigation prompts; the microphone captures the rider's voice, enabling voice input.

[0027] Please refer to it again. Figures 1 to 3The main unit 20 includes a housing assembly 210, a control assembly (not shown), a control device 230, and a battery. A mounting cavity 212 is formed inside the housing assembly 210. The battery is installed in the mounting cavity 212 and provides power to the control assembly, control device 230, and other electronic devices. The battery can be a dry cell battery, a rechargeable battery, or the like. The control assembly, installed in the mounting cavity 212, can be a circuit board, a microcontroller (MCU), a programmable logic controller (PLC), or the like, and is responsible for controlling and coordinating the operation of the entire system. The control device 230 is configured for manual control by the user and transmits relevant electrical signals to the control assembly. The control assembly controls the audio components to execute corresponding instructions based on the electrical signals.

[0028] Please continue reading. Figures 1 to 3 The base 10 is equipped with a first electrical connector 140 and a signal connection port 170. The audio cable plug of the audio component can be inserted into the signal connection port 170 and electrically connected to the first electrical connector 140. The main unit 20 is equipped with a second electrical connector 240 that is electrically connected to the control component. When the main unit 20 is installed on the base 10, the first electrical connector 140 and the second electrical connector 240 are in contact and conductive. When the first electrical connector 140 and the second electrical connector 240 are conductive, the audio component is signal-connected to the control component through the first electrical connector 140 and the second electrical connector 240.

[0029] In this embodiment, since the audio cable plug remains connected to the signal connection port 170 of the base 10, there is no need to disassemble the audio cable during the disassembly of the host 20 and the base 10. This not only reduces the operation of the audio cable and avoids problems such as interface wear and poor contact that may be caused by frequent plugging and unplugging of the audio cable, effectively extending the service life of the audio cable and related interfaces, but also avoids problems such as forgetting to unplug the cable and causing the host 20 to fall. This greatly facilitates the installation and disassembly of the host 20 and the base 10.

[0030] Please see Figures 1 to 3The base 10 also includes a power supply (not shown in the figure), which is electrically connected to the first electrical connector 140. When the main unit 20 is mounted on the base 10, the first electrical connector 140 and the second electrical connector 240 make contact and conduct, and the power supply provides power to the control components through the first electrical connector 140 and the second electrical connector 240. In this embodiment, the base 10 is equipped with a power supply, so the main unit 20 automatically starts charging as soon as it is mounted on the base 10. It should be noted that the main unit 20 itself is also equipped with a battery, which serves as an internal energy reserve, providing stable power to electronic components such as the control components. The power supply of the base 10 further expands the power reserve during outdoor use, effectively extending the continuous operating time of the helmet Bluetooth walkie-talkie 1 and improving its practicality and reliability. In addition, the main unit 20 is also equipped with a charging port for charging the battery, and similarly, the base 10 is also equipped with a charging port for charging the power supply. The charging port can be a Type-C interface, a USB interface, or other similar types.

[0031] In some embodiments, both the first electrical connector 140 and the second electrical connector 240 are spring-loaded connectors. Spring-loaded connectors provide stable pressure upon contact, ensuring good continuity of the signal transmission line.

[0032] To achieve a convenient, stable, and reliable detachable connection between the main unit 20 and the base 10, the structure of the base 10 has been improved in this embodiment. Please refer to the following references. Figure 4 and Figure 5 The improved base 10 includes a housing assembly 110 and a connecting mechanism 120 disposed on the housing assembly 110.

[0033] Please see Figure 4 and Figure 5 The connecting mechanism 120 includes a first latching member 121, a second latching member 122, a reset member 123, and a lever 124, all linked together. The outer surface of the base shell 2111 of the main unit 20 has a first engaging portion 216 corresponding to the first latching member 121 and a second engaging portion 217 corresponding to the second latching member 122. In the locked state, the reset member 123 drives the first latching member 121 and the second latching member 122 closer together, causing the first latching member 121 to engage with the first engaging portion 216 and the second latching member 122 to engage with the second engaging portion 217, thereby fixing the main unit 20 to the base 10. In the open state, the user only needs to control the lever 124. Through the mechanical transmission of the lever 124, the first latching member 121 and the second latching member 122 are driven away from each other, thereby releasing their latching relationship with the first engaging portion 216 and the second engaging portion 217, allowing the main unit 20 to be detached from the base 10.

[0034] Based on the above embodiments, users can quickly connect and disconnect the main unit 20 from the base 10 without any tools, simply by operating the lever 124. This greatly saves time and effort, providing users with an efficient and convenient user experience. The reset component 123 provides an automatic reset function for the connecting mechanism 120. After each disassembly of the main unit 20, the reset component 123 automatically restores the first latching member 121 and the second latching member 122 to their locked positions, preparing for the next connection.

[0035] Please see Figures 4 to 6 To further improve the convenience and stability of the connection between the host 20 and the base 10, in some embodiments, the base 10 is provided with a first magnetic 150, and the host 20 is provided with a second magnetic 270. Both the first magnetic 150 and the second magnetic 270 can be made of high-performance magnetic materials, such as neodymium iron boron magnets, which can generate a stable magnetic field. When the host 20 gradually approaches the base 10, the magnetic fields between the first magnetic 150 and the second magnetic 270 begin to interact, generating a magnetic force that attracts each other, allowing the host 20 to automatically adhere to the base 10, achieving a quick and stable connection. In addition, the magnetic attraction also has an auxiliary positioning function. The strong magnetic attraction can be used to pre-position the host 20 roughly near a suitable position on the base 10. Then, by finely adjusting the relative position of the host 20 and the base 10, it can be ensured that the first latching member 121 and the second latching member 122 can engage with the first latching part 216 and the second latching part 217, respectively.

[0036] Please see Figure 4 and Figure 5 In some embodiments, the first latching member 121 includes a first latching portion 1211 and a first force-receiving portion 1212 connected together, and the second latching member 122 includes a second latching portion 1221 and a second force-receiving portion 1222 connected together; the lever 124 is rotatably connected to the base 10 and includes a first driving portion 1241, a second driving portion 1242, and an operating portion 1243 connected together; when the operating portion 1243 controls the first driving portion 1241 to act on the first force-receiving portion 1212 and the second driving portion 1242 to act on the second force-receiving portion 1222, the first latching portion 1211 and the second latching portion 1221 are moved away from each other. The first latching member 121, the second latching member 122, and the lever 124 can all be injection molded from plastic, thus forming an integral structure. This integral structure not only enhances the overall structural strength but also effectively improves the service life.

[0037] In addition, to further improve the smoothness of operation, the first force-receiving part 1212, the second force-receiving part 1222, the first drive part 1241, and the second drive part 1242 are all specially provided with smooth transition arc-shaped surfaces. When these components come into contact with each other and drive each other, the arc-shaped surfaces can reduce frictional resistance, making the driving process smoother and more natural, and bringing a more comfortable operating experience to the user.

[0038] Please see Figure 4 In some embodiments, the housing assembly 110 is provided with a receiving cavity 113 and a first opening 114, a second opening 115 and an operating port 116 communicating with the receiving cavity 113. The cavity wall of the receiving cavity 113 is formed with a guide structure 117. The first force-receiving part 1212 and the second force-receiving part 1222 are placed in the receiving cavity 113 and can move along the guide structure 117. Through the constraint of the guide structure 117, the first force-receiving part 1212 and the second force-receiving part 1222 can be prevented from deviating or shaking during movement, ensuring the stability of the engagement between the locking part and the engaging part.

[0039] In some embodiments, the guide structure 117 can be configured as a guide groove, which can be formed in two ways: one is to further recess the cavity wall of the mounting cavity 212 to directly shape the guide groove. This results in a simple structure, convenient manufacturing, and provides stable guidance for the force-bearing part. The other way is to provide a limiting boss 1171 protruding from the cavity wall of the mounting cavity 212. The limiting boss 1171 cooperates with the cavity wall of the mounting cavity 212 to form the guide groove. The protruding structure of the limiting boss 1171 enhances the constraint capability of the guide groove and improves the accuracy of the movement of the force-bearing part. In other embodiments, the guide structure 117 can be a guide boss, with the first force-bearing part 1212 and the second force-bearing part 1222 correspondingly provided with guide grooves. The guide boss is inserted into the guide groove, allowing the first force-bearing part 1212 and the second force-bearing part 1222 to move along the extension direction of the guide boss. This embodiment does not limit the specific form of the guide structure 117.

[0040] The first latching part 1211 extends outward through the first opening 114, and the second latching part 1221 extends outward through the second opening 115, allowing the latching parts to be tightly latched with the latching parts on the main unit 20 when needed, thus completing a stable connection between the main unit 20 and the base 10. Simultaneously, the free end of the operating part 1243 extends out of the housing assembly 110 through the operating port 116 for easy user operation. In use, the user can easily drive the lever 124, and through the combined action of the lever 124 and the reset member 123, control the two latching parts to move away from or closer to each other, thereby connecting or separating the main unit 20 from the base 10.

[0041] Please refer to the following: Figure 4In some embodiments, the outer casing assembly 110 includes a cover 111 and a cap 112, which together form a receiving cavity 113. The cover 111 may be provided with the aforementioned guide structure 117, first opening 114, second opening 115, and operating port 116. In terms of material and molding process, both the cover 111 and the cap 112 can be made of plastic and manufactured using injection molding. This process not only ensures the dimensional accuracy and surface quality of the casing but also has advantages such as high production efficiency and low cost. Regarding the connection method, the cover 111 and the cap 112 can be fixed together using various methods such as snap-fit ​​connection and screw connection. Snap-fit ​​connection is simple to operate and quick to assemble and disassemble, enabling a tight fit between the casings; screw connection has the characteristics of strong connection and high reliability, and can be flexibly selected according to actual needs.

[0042] To achieve a rotatable connection between the lever 124 and the housing assembly 110, the housing 111 is provided with a pivot hole, and the lever 124 has a corresponding pivot portion 1244. During assembly, the pivot hole is fitted onto the pivot portion 1244, allowing the lever 124 to rotate freely around the pivot portion 1244. This rotatable connection method is not only simple and reliable in structure, but also ensures that the lever 124 rotates smoothly and steadily, thereby guaranteeing the overall operational flexibility and stability of the connecting mechanism 120.

[0043] Please see Figure 5In some embodiments, the operating part 1243 has a first sleeve part 1245 protruding from the side opposite to the first force-receiving part 1212 and the second force-receiving part 1222, and a corresponding second sleeve part 119 protruding from the cavity wall of the receiving cavity 113. Optionally, the second sleeve part 119 is disposed on the cover 111. The reset member 123 is a compression spring 1231, which is sleeved on the first sleeve part 1245 and the second sleeve part 119. The two ends of the compression spring 1231 are respectively the operating part 1243 and the cavity wall of the receiving cavity 113. When the user applies external force to the operating part 1243, the lever 124 will drive the first force-receiving part 1212 and the second force-receiving part 1222 to move under the drive of the external force, so that the first locking member 121 and the second locking member 122 move away from each other, thereby providing the space required for the main unit 20 to be connected or separated from the base 10. For example, when connecting the main unit 20 and the base 10, as the latching parts move, they can smoothly engage with the engaging parts on the main unit 20; and when separating, the latching parts can disengage from the engaging parts. During this process, the compression spring 1231 is gradually compressed as the operating part 1243 moves. When the user stops applying external force, the compression spring 1231, with its good elastic properties, quickly generates a reverse elastic force, pushing the operating part 1243 to move in the opposite direction to the previous movement, thereby causing the lever 124 to quickly return to its initial position. In this embodiment, the compression spring 1231 is sleeved on the first socket 1245 and the second socket 119, making the installation and fixation of the compression spring 1231 more stable and ensuring the stability of the connecting mechanism 120.

[0044] Please see Figure 5 In some embodiments, the first force-receiving part 1212 and the second force-receiving part 1222 are arranged opposite to each other, and an assembly space 1224 is formed between them. The reset member 123 is a tension spring 1232, which is disposed in the assembly space 1224 and its two ends are respectively connected to the first force-receiving part 1212 and the second force-receiving part 1222. In this example, the tension spring 1232 provides a pulling force to the first force-receiving part 1212 and the second force-receiving part 1222 to bring them closer together, so that the first snap-fit ​​member 121 and the second snap-fit ​​member 122 have the potential energy for reset.

[0045] Please see Figure 4 and Figure 5To improve the stability of the tension spring 1232 within the assembly space 1224, in some embodiments, a first receiving groove 1213 is provided on the side of the first force-receiving part 1212 facing the second force-receiving part 1222, and a second receiving groove 1223 is provided on the side of the second force-receiving part 1222 facing the first force-receiving part 1212. The first receiving groove 1213 and the second receiving groove 1223 constitute part of the assembly space 1224, and both ends of the tension spring 1232 are respectively received in the first receiving groove 1213 and the second receiving groove 1223. During assembly, the receiving grooves serve to position the ends of the tension spring 1232. Assembly personnel can quickly place both ends of the tension spring 1232 into the two receiving grooves, improving production efficiency. Moreover, the groove walls can limit the radial deformation of the ends of the tension spring 1232, improving the long-term stability and reliability of the reset mechanism.

[0046] Please see Figure 1 In some embodiments, when the helmet Bluetooth walkie-talkie 1 is in use, the lever 124 is moved in a forward and backward direction. This direction of operation is for the convenience of the user, and the forward and backward movement design greatly facilitates the installation of the connecting mechanism 120 within the housing assembly 110.

[0047] For user convenience in controlling the audio components via control device 230, please refer to [link / reference]. Figures 6 to 10 This embodiment also makes further improvements to the control device 230, which includes a reset encoder 231 and a toggle assembly 232.

[0048] Please see Figure 6 The reset encoder 231 is installed in the mounting cavity 212 and electrically connected to the control component. In principle, the reset encoder 231, as a sensor for measuring mechanical rotation or displacement, is based on photoelectric, magnetic, or inductive technology and can convert angular or linear displacement into electrical signals. In this embodiment, the reset encoder 231 incorporates an automatic reset mechanism, which can employ a metal memory spring. When the drive shaft of the reset encoder 231 moves, the metal memory spring causes the drive shaft to automatically reset and spring back. The reset encoder 231 can convert the angular displacement of the drive shaft into a corresponding electrical signal based on the toggle assembly 232's actuation state and send it to the control component. Upon receiving the electrical signal, the control component precisely controls the operating state of the audio component according to the different toggle assemblies 232's actuation states, such as adjusting volume, switching music tracks, answering or hanging up calls, etc.

[0049] In this application, the control device 230 is simple to operate. Users can easily control various audio components by simply toggling the toggle assembly 232. The operation of the toggle assembly 232 takes into account the special characteristics of cycling scenarios. During cycling, riders usually need to wear thick gloves for safety. The toggle assembly 232 in this embodiment allows riders to operate the device easily and freely even while wearing thick gloves, without the need for cumbersome removal of gloves. This improves the practicality and user-friendliness of the helmet device, providing riders with a more convenient and comfortable user experience.

[0050] Please see Figures 7 to 9 In some embodiments, when the main unit 20 is mounted on the helmet and in a wearing state, the toggle assembly 232 is moved in a vertical direction, such as... Figure 7 As shown, the first position is located above the neutral position, as... Figure 9 As shown, the second position is located below the neutral position. In this example, after the user has put on the helmet, based on the natural relative position of the head and hands, operating the toggle assembly 232 in the vertical direction is more convenient and ergonomic, effectively improving the user's operating experience. Of course, in other embodiments, the direction of movement of the toggle assembly 232 can also be adjusted to the horizontal direction according to actual needs, specifically the forward / backward or left / right direction. This application does not limit the direction of movement of the toggle assembly 232, aiming to provide users with diverse operating options to adapt to different usage scenarios and user habits.

[0051] Please see Figure 6 The housing assembly 210 includes a main housing 211, which comprises a bottom housing 2111 and a top housing 2112. The bottom housing 2111 and the top housing 2112 enclose the aforementioned mounting cavity 212. Both the bottom housing 2111 and the top housing 2112 can be made of plastic and manufactured using injection molding. This process not only ensures the dimensional accuracy and surface quality of the housing but also offers advantages such as high production efficiency and low cost. Regarding the connection method, the bottom housing 2111 and the top housing 2112 can be fixed together using various methods such as snap-fit ​​connections and screw connections. Snap-fit ​​connections are simple to operate and quick to assemble and disassemble, enabling a tight fit between the housings; screw connections offer strong and reliable connections, and can be flexibly selected according to actual needs.

[0052] Please see Figure 6 and Figure 10In some embodiments, the toggle assembly 232 includes a toggle element 233, which includes a connecting portion 2331 and a toggle portion 2332 connected together. The connecting portion 2331 is rotatably housed within a mounting hole 218 and extends into a mounting cavity 212 for transmission connection with the reset encoder 231. The connecting portion 2331 fits tightly with the wall of the mounting hole 218, allowing the toggle portion 2332 to move up and down vertically around the connecting portion 2331 as a pivot. In actual use, when the user toggles the toggle portion 2332, the connecting portion 2331 transmits the rotational motion of the toggle portion 2332 to the reset encoder 231. The reset encoder 231 outputs a corresponding electrical signal to the control component according to the rotation direction of the toggle portion 2332, thereby enabling the control component to control the audio component.

[0053] Please see Figure 6 and Figure 10 In some embodiments, the toggle assembly 232 further includes a button 234 connected to the end of the toggle assembly 233 away from the reset encoder 231 and configured for user pressing. The toggle state of the toggle assembly 232 includes the state in which the button 234 is axially pressed; wherein the button 234 and the toggle assembly 233 are integrally formed or separately configured.

[0054] In some embodiments, the button component 234 and the toggle component 233 are separate components; the button component 234 includes a mounting portion 2341 and a button portion 2342 connected together. The toggle component 233 has a receiving groove 2335 on the side facing away from the connecting portion 2331, and the mounting portion 2341 is disposed in the receiving groove 2335; the button portion 2342 protrudes from the receiving groove 2335 for pressing. Specifically, the button component 234 can drive the toggle component 233 to move axially. The reset encoder 231 receives the signal of the toggle component 233 moving axially and sends a corresponding electrical signal to the control component based on the signal. Thus, the toggle component 232 has a variety of toggle states, including not only simple toggle of the toggle component 233 to a first or second position, but also axial movement of the button component 234. Furthermore, the toggle component 233 and the button component 234 can be further subdivided into long toggle and short toggle states to meet different functional requirements.

[0055] The reset encoder 231 is configured to respond to various operations and generate corresponding control signals. Specifically, the reset encoder 231 generates a first control signal in response to the up-and-down movement of the toggle 233 and generates a second control signal in response to the axial pressing of the button 234; the control component is configured to control the audio component to perform volume adjustment or song switching operations according to the first control signal, and to control the radio function switch or radio channel switching of the audio component according to the second control signal.

[0056] To more clearly define the operating states, a short dial can be set to a one-second duration, while a long dial can be flexibly set to a two- or three-second duration depending on actual usage needs. Here is a specific application example: when toggle 233 is moved to the first position for one second, the control component controls the audio component to play the previous track; when toggle 233 is moved to the second position for one second, the control component controls the audio component to play the next track; when toggle 233 is moved to the first position for two seconds, the control component increases the audio component volume; when toggle 233 is moved to the second position for two seconds, the control component decreases the audio component volume. Similarly, when button 234 is axially pressed for one second, the radio function is turned on or off; when button 234 is axially pressed for two seconds, the radio channel is switched. This diverse dialing state and control method provides users with a more convenient and efficient operating experience.

[0057] Please see Figure 6 and Figure 10 To improve the stability of the connection between the button 234 and the toggle 233, in some embodiments, the housing assembly 210 further includes a limiting member 213. The limiting member 213 has a clearance hole 2131, the shape and size of which are adapted to the button portion 2342 to ensure that the button portion 2342 can pass through it smoothly. The limiting member 213 is fixed to the face shell 2112 to form a stable overall structure. The limiting member 213 and the face shell 2112 can be fixed with screws. During installation, the button portion 2342 passes through the clearance hole 2131, while the limiting member 213 abuts against the toggle portion 2332 and the mounting portion 2341, effectively limiting the axial movement of the toggle assembly 232 and preventing axial movement of the toggle assembly 232 during use, thereby greatly improving the stability and reliability of the connection.

[0058] In addition, to further optimize the structural design and user experience, the button part 2342 and the connecting part 2331 are coaxially arranged. This coaxial arrangement not only makes the structure of the toggle assembly 232 more compact and reasonable, but also ensures the smoothness and accuracy of the toggle operation, allowing users to experience a smoother and more comfortable operating feel when using the toggle assembly 232.

[0059] Please see Figure 6In some embodiments, the outer periphery of the mounting portion 2341 is provided with an annular protrusion 2343, and the opening of the receiving groove 2335 is correspondingly provided with an annular groove 2336. The depth and width of the annular groove 2336 match the annular protrusion 2343, so that the annular protrusion 2343 can be precisely embedded in the annular groove 2336 to form a tight locking structure. This not only increases the contact area between the button 234 and the toggle 233, but also effectively prevents relative movement between the two. The limiting member 213 abuts against the annular protrusion 2343, further restricting the axial movement of the button 234, ensuring that the button 234 is fixed in position in the toggle assembly 232. Even under frequent operation or external impact, it can maintain a stable connection state and will not loosen or fall off.

[0060] Please see Figure 10 In some embodiments, the outer surface of the faceplate 2112 is provided with an assembly groove 214, and a limiting member 213 is installed in the assembly groove 214. The outer surface of the limiting member 213 is flush with the outer surface of the main shell 211. This reduces the abruptness caused by the protruding limiting member 213, making the appearance of the main shell 211 smoother and more streamlined. When the device is used in scenarios where appearance is important, such as helmets, the smooth appearance can better integrate with the overall style of the helmet, improving the overall aesthetics of the product and enhancing the user's visual experience.

[0061] Please see Figure 10 In some embodiments, a mounting groove 215 is formed on the outer surface of the faceplate 2112, and at least a portion of the toggle assembly 232 is housed within the mounting groove 215. During daily use, the toggle assembly 232 may be subjected to external forces such as impacts and scratches; the mounting groove 215 can provide some physical protection for the toggle assembly 232. Compared to the toggle assembly 232 protruding directly from the outer surface of the main housing 211, the mounting groove 215 in this embodiment allows the toggle assembly 232 to better integrate with the faceplate 2112, resulting in a cleaner and more aesthetically pleasing appearance. The mounting groove 215 can also partially conceal the toggle assembly 232, making the overall appearance of the device more streamlined.

[0062] Please see Figure 10In some embodiments, the bottom wall of the mounting groove 215 is concave in an arc shape. The actuating part 2332 includes an arc-shaped segment 2333 and a lever 2334 disposed on the outer surface of the arc-shaped segment 2333. The arc-shaped segment 2333 is connected to the connecting part 2331 and is provided with the aforementioned receiving groove 2335. The arc-shaped segment 2333 is adapted to the arc-shaped bottom wall of the mounting groove 215, while the lever 2334 protrudes from the mounting groove 215, facilitating the user's toggle operation. The bottom wall of the concave mounting groove 215 fits with the arc-shaped segment 2333 of the toggle component 233. The mounting groove 215 not only positions the toggle component 233, but also effectively limits the shaking and offset of the toggle component 233 when the user toggles the toggle assembly 232, ensuring that the toggle component 233 always moves stably along a predetermined trajectory.

[0063] Please see Figures 7 to 9 The main unit 20 also includes a power switch 250 and a Bluetooth communication button 260. Both the power switch 250 and the Bluetooth communication button 260 are signal-connected to the control components. The power switch 250 is used to control the power on and off of the main unit 20, while the Bluetooth communication button 260 is used to control the Bluetooth function of the main unit 20 to be turned on, off, or paired. The power switch 250 is located on the faceplate 2112 and is situated on one side of the toggle assembly 232. When worn, both the power switch 250 and the toggle assembly 232 are located on the outward-facing side of the faceplate 2112, i.e., the side furthest from the user's head. The Bluetooth communication button 260 is located on the top of the faceplate 2112, thus facilitating operation by the user while riding.
