Description

Technical Field

[0001] This utility model relates to the field of walkie-talkie technology, and in particular to a walkie-talkie for cycling helmets. Background Technology

[0002] Helmet talkies for cycling allow riders to communicate in real time with companions, command centers, or other relevant personnel while operating the vehicle with both hands, greatly improving cycling safety and teamwork.

[0003] In these complex and diverse cycling environments, dust and water resistance has become a key factor in the stable and reliable operation of cycling helmet walkie-talkies. During cycling, vehicles kick up a lot of dust, especially on unpaved roads or near construction sites where dust concentrations are high. At the same time, weather conditions are unpredictable; sudden rain or humid fog can expose the walkie-talkie to moisture. If the walkie-talkie's dust and water resistance is insufficient, dust particles may enter the device, adhere to electronic components, affect electronic signal transmission, and even cause short circuits. Moisture intrusion, on the other hand, can directly damage the circuitry, rendering the walkie-talkie malfunction.

[0004] Existing walkie-talkies typically use separate rubber gaskets for sealing the buttons. However, this separate design creates numerous gaps and interfaces between the button gaskets and the outer casing. Dust and moisture can easily seep into the area beneath the buttons through these gaps, and subsequently penetrate into critical components such as the circuit boards inside the walkie-talkie.

[0005] Therefore, existing helmet walkie-talkies for cycling need to be improved to overcome the shortcomings of the current technology. Utility Model Content

[0006] To overcome the problems existing in related technologies, the purpose of this utility model is to provide a cycling helmet walkie-talkie with strong dust and water resistance, which can reduce the impact of dust and moisture on the internal components of the body, thereby improving the working stability of the walkie-talkie and extending its service life.

[0007] A cycling helmet walkie-talkie includes a main body, which includes a bottom shell and a face mask that are fixed to each other, forming a mounting cavity between the bottom shell and the face mask, and a control circuit board is disposed in the mounting cavity;

[0008] The mask has a first control area and a second control area on its side wall and top, respectively, and both the first control area and the second control area are provided with a number of control buttons.

[0009] The inner wall of the mask is provided with a rubber pad, which completely covers the first control area and the second control area. The rubber pad is provided with button protrusions corresponding to the control buttons.

[0010] In a preferred embodiment of this invention, a sealing protrusion is provided at the bottom of the rubber pad, and the sealing protrusion is located at the connection between the bottom shell and the face mask.

[0011] In a preferred embodiment of this invention, the sealing protrusion is stepped and has a groove on its upper surface. A locking block is provided at the connection between the face mask and the bottom shell, and the locking block is adapted to the groove.

[0012] In a preferred embodiment of this invention, a storage battery is further provided inside the mounting cavity, and the storage battery is electrically connected to the control circuit board.

[0013] After the bottom shell and the face shield are fixed together, the rubber pad covers the periphery of the battery.

[0014] In a preferred embodiment of this invention, the face mask is provided with a charging interface, which is electrically connected to the battery; a sealing gasket is provided at the charging interface.

[0015] In a preferred embodiment of this utility model, a clamping member is provided on one side wall of the bottom shell. The clamping member includes a base plate and a clamping plate. The base plate is fixed on the bottom shell, and the clamping plate is disposed on one side of the base plate. The clamping plate is hinged to the base plate, and a torsion spring is provided at the hinge point between the clamping plate and the base plate.

[0016] In a preferred embodiment of this invention, an antenna is also provided on the main body, and the antenna passes through the face mask and is electrically connected to the control circuit board.

[0017] In a preferred embodiment of this invention, the edges of both the face mask and the bottom shell are provided with rounded corners or chamfers.

[0018] The beneficial effects of this utility model are as follows:

[0019] This utility model provides a helmet walkie-talkie for cycling, comprising a main body, which includes a bottom shell and a face mask fixed to each other, forming a mounting cavity between the bottom shell and the face mask. A control circuit board is disposed within the mounting cavity. The side wall and top of the face mask are respectively provided with a first control area and a second control area, each with several control buttons. A rubber pad is provided on the inner wall of the face mask, completely covering the first and second control areas. The rubber pad has button protrusions corresponding to the control buttons. When in use, the rider operates the walkie-talkie by pressing the button protrusions on the rubber pad. The pressure on the button protrusions compresses the corresponding control buttons, causing the bottom contact of the control button to contact the trigger circuit on the control circuit board, triggering functions such as powering on, switching channels, adjusting volume, and initiating a call. Because the rubber pad completely covers both the first and second control areas, in the non-operational state, the rubber pad fits tightly against the inner wall of the mask, forming a continuous seal. External dust and moisture cannot enter the mounting cavity through the gap between the control button and the mask. During operation, although the button protrusion deforms when pressed, the remaining area of ​​the rubber pad remains sealed to the mask, and the elasticity of the rubber pad fills the gap between the button protrusion and the control button, effectively preventing dust and moisture intrusion. Because dust and moisture are difficult to penetrate, internal components such as the control circuit board experience less dust adhesion, reducing short circuits and corrosion caused by moisture, thus lowering the probability of component failure and ensuring long-term stable operation of the walkie-talkie.

[0026] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0027] Dust and water resistance are crucial factors for the stable and reliable operation of walkie-talkies in cycling helmets. During cycling, vehicles generate significant amounts of dust, especially on unpaved roads or near construction sites where dust concentrations are high. Furthermore, unpredictable weather conditions, such as sudden rain or humid fog, can expose walkie-talkies to moisture. If the walkie-talkie's dust and water resistance is insufficient, dust particles can enter the device, adhere to electronic components, affect signal transmission, and even cause short circuits. Moisture intrusion can directly damage the circuitry, rendering the walkie-talkie malfunction.

[0028] Existing walkie-talkies typically use separate rubber gaskets for sealing the buttons. However, this separate design creates numerous gaps and interfaces between the button gaskets and the outer casing. Dust and moisture can easily seep into the area beneath the buttons through these gaps, and subsequently penetrate into critical components such as the circuit boards inside the walkie-talkie. Example

[0029] See Figures 1-4 The present embodiment provides a walking radio for a cycling helmet, which includes a main body. The main body includes a bottom shell 2 and a face mask 1 that are fixed to each other. A mounting cavity is formed between the bottom shell 2 and the face mask 1. A control circuit board is disposed in the mounting cavity.

[0030] The mask 1 has a first control area 11 and a second control area 12 on its side wall and top, respectively, and both the first control area 11 and the second control area 12 are provided with a number of control buttons.

[0031] The inner wall of the mask 1 is provided with a rubber pad 5, which completely covers the first control area 11 and the second control area 12. The rubber pad 5 is provided with button protrusions corresponding to the control buttons.

[0032] Specifically, the main body of the cycling helmet walkie-talkie consists of a base shell 2 and a face mask 1. The two are securely connected using conventional fixing methods such as snap-fit ​​and screw fastening. The control circuit board is installed in the mounting cavity using screws or slots, maintaining a certain distance from the base shell 2 and face mask 1 to avoid direct contact that could lead to poor heat dissipation or damage from stress. A first control area 11 is defined on the side wall of the face mask 1, and a second control area 12 is defined on the top. Based on actual functional requirements, several control buttons, such as a power switch and channel switching button, are set in the first control area 11; several control buttons, such as volume adjustment and call / hang-up buttons, are set in the second control area 12 (e.g., two buttons corresponding to volume up and call / hang-up functions). These control buttons use a conventional button structure, with their bottoms corresponding to trigger contacts on the control circuit board. Pressing them activates the circuit and triggers the corresponding function.

[0033] The rubber pad 5 is made of rubber material with good elasticity, sealing properties, and wear resistance. It is custom-cut to fit the shape of the inner wall of the face mask 1. The rubber pad 5 completely covers the first control area 11 and the second control area 12. At the position corresponding to each control button, a button protrusion adapted to the button shape is pre-fabricated. In its natural state, the button protrusion is in close contact with the control button, ensuring sensitive triggering. The rubber pad 5 is fixed to the inner wall of the face mask 1 by applying an environmentally friendly adhesive. During application, the adhesive is ensured to be evenly distributed, ensuring a firm fit for the rubber pad 5 without affecting its elastic deformation. The integrated rubber pad 5 design simplifies the sealing structure of the walkie-talkie, reducing the number of parts and assembly steps compared to multiple sealing components. In the production process, it improves assembly efficiency, reduces the risk of seal failure due to assembly errors, and is beneficial for large-scale industrial production.

[0034] In the aforementioned type of helmet walkie-talkie, when the rider operates the walkie-talkie, pressing the button protrusion on the rubber pad 5 causes the button protrusion to press against the corresponding control button, making the bottom contact of the control button contact the trigger circuit on the control circuit board, triggering functions such as powering on, switching channels, adjusting volume, and initiating a call. Since the rubber pad 5 completely covers the first control area 11 and the second control area 12, in the non-operating state, the rubber pad 5 is tightly fitted to the inner wall of the face mask 1, forming a continuous sealing surface. External dust and moisture cannot enter the mounting cavity through the gap between the control button and the face mask 1. During operation, although the button protrusion is deformed by pressing, the remaining area of ​​the rubber pad 5 remains sealed to the face mask 1, and the gap between the button protrusion and the control button is filled by the elasticity of the rubber pad 5 itself, effectively preventing dust and moisture intrusion. Because dust and moisture are difficult to penetrate, the internal components such as the control circuit board have less dust adhesion, reducing short circuits and corrosion problems caused by moisture, thereby reducing the probability of component failure and ensuring long-term stable operation of the walkie-talkie.

[0035] More preferably, the bottom of the rubber pad 5 is provided with a sealing protrusion 51, which is located at the connection between the bottom shell 2 and the face mask 1.

[0036] Furthermore, the sealing protrusion 51 is stepped, and a groove is provided on the upper part of the sealing protrusion. A locking block is provided at the connection between the face mask 1 and the bottom shell 2, and the locking block is adapted to the groove.

[0037] The sealing protrusion 51 at the bottom of the rubber pad 5 acts on the critical gap at the connection between the bottom shell 2 and the face mask 1, which is prone to dust and water ingress. The original seal relied solely on the connection between the bottom shell 2 and the face mask 1, but now includes secondary protection from the sealing protrusion 51 of the rubber pad 5. The stepped design, combined with the slot-block structure, ensures a tighter fit between the sealing protrusion 51 and the connection, forming a dual sealing system of "rubber pad 5 main sealing control area + sealing protrusion 51 sealing the joint seam." For example, during a heavy rain while cycling, rainwater is unlikely to seep in through the gap between the bottom shell 2 and the face mask 1. Even if there is a small amount of moisture, it will be blocked by the sealing protrusion 51, significantly reducing the risk of water entering the mounting cavity and protecting the internal circuitry and components.

[0038] The matching structure of the slot and the locking block provides precise positioning for the assembly of the rubber pad 5, the base shell 2, and the face shield 1. During assembly, the locking block embeds into the slot, quickly aligning the relative positions of the rubber pad 5 with the base shell 2 and the face shield 1, reducing manual assembly errors and improving production efficiency. For walkie-talkies produced in batches, workers can use this structure to quickly complete the installation of the sealing components, ensuring consistent sealing performance for each product.

[0039] In a specific embodiment, a storage battery is also provided inside the mounting cavity, and the storage battery is electrically connected to the control circuit board;

[0040] After the bottom shell 2 and the face shield 1 are fixed together, the rubber pad 5 covers the periphery of the battery.

[0041] Furthermore, the face mask 1 is provided with a charging interface, which is electrically connected to the battery; a sealing gasket 13 is provided at the charging interface.

[0042] The rubber gasket 5 further expands the sealing range by covering the battery. The small gaps that might exist between the battery and the faceplate 1 and bottom shell 2 are filled by the rubber gasket 5, preventing dust and moisture from accumulating on the battery surface. The charging interface, as a component exposed to the faceplate 1, has a gap with the faceplate 1 that is a significant channel for dust and moisture intrusion. The annular sealing gasket 13 completely seals this gap. When not charging, the sealing gasket 13 tightly fits the charging interface and mounting hole, preventing rainwater and dust from entering the mounting cavity from the interface.

[0043] Furthermore, a clamping member 3 is provided on one side wall of the bottom shell 2. The clamping member 3 includes a base plate 31 and a clamping plate 32. The base plate 31 is fixed on the bottom shell 2. The clamping plate 32 is disposed on one side of the base plate 31. The clamping plate 32 is hinged to the base plate 31, and a torsion spring is provided at the hinge point between the clamping plate 32 and the base plate 31.

[0044] With the help of the torsion spring driven clamp 32 and base plate 31 structure, the walkie-talkie and helmet can be disassembled and assembled without additional tools. During installation, simply bend the clamp 32, place it on the edge of the helmet, and loosen the fixation. The operation steps are simple and suitable for different installation occasions.

[0045] Furthermore, an antenna 4 is also provided on the main body, and the antenna 4 passes through the mask 1 and is electrically connected to the control circuit board.

[0046] Antenna 4 penetrates the faceplate 1 and is directly electrically connected to the control circuit board, reducing signal loss along the transmission path. Its exposed design also prevents signal obstruction and interference from components inside the mounting cavity. Antenna 4 can receive and transmit wireless signals more efficiently, improving the clarity of intercom calls and extending the transmission distance.

[0047] Furthermore, the edges of both the face mask 1 and the bottom shell 2 are provided with rounded corners or chamfers.

[0048] The rounded / beveled edges of the face shield 1 and the base shell 2 eliminate sharp edges, preventing riders from being scratched on their hands or face when installing, removing, or using the walkie-talkie. At the same time, it also prevents the sharp edges from abrading the helmet shell or the rider's clothing when the walkie-talkie is fixed to the helmet, thus improving safety.
