[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0033] Example 1: See Figures 1-7As shown, a vehicle-mounted intercom device includes a housing 1, a circuit board 2 disposed within the housing 1, and a battery 3. The battery 3 supplies power to the circuit board 2. From top to bottom, the front end of the housing 1 has a display area, a button area, and an audio media area. The display area has a display screen assembly 4. The button area has at least three horizontally distributed control buttons 5. Inside the housing 1, a speaker 6 and a microphone 7 are disposed opposite the audio media area. The left side of the housing 1 has a PTT button 8 and a volume adjustment button 9. The circuit board 2 has button elements corresponding to each button. The right side of the housing 1 has a spring-loaded SIM card slot 10. The bottom of the housing 1 has a power connector 11, which is connected to the battery 3 via the circuit board 2. The housing 1 also contains a wireless transceiver module 12 and a Wi-Fi module. The display screen assembly 4, the speaker 6, the microphone 7, the button elements, the spring-loaded SIM card slot 10, the wireless transceiver module 12, the Wi-Fi module, and the power connector 11 are all connected to the circuit board 2.

[0034] In this embodiment, the circuit board includes a storage module and a processing module 13. The storage module is a storage chip used to store the corresponding control program, and the processing module is a microcontroller or CPU used to control the operation of the entire control program. There are three control buttons: an OK button, a menu button, and an exit button. Pressing the menu button displays the preset menu on the display screen. Pressing the OK button confirms the selected option, and the exit button returns to the previous menu or exits the menu back to the home page. The battery powers the internal components, and the power connector charges the battery. The audio medium area is a perforated structure on the front sidewalls of multiple housings. The speaker and microphone are located inside the housing, directly opposite the perforation, allowing sound to be transmitted through the microphone and emitted through the speaker during intercom. A waterproof component is installed in the perforated structure for waterproofing. A spring-loaded SIM card slot is used to install the SIM card, enabling wireless data transmission via the wireless transceiver module. The Wi-Fi module allows the intercom device to transmit data using Wi-Fi. In this invention, depending on the application, a SIM card can be selected for 2G, 3G, 4G, or 5G voice and data calls or corresponding data transmission. It can also be used for wireless data calls or corresponding data transmission via Wi-Fi. The PTT button is used for real-time communication, and the volume control buttons are used to adjust the speaker volume. This invention allows the walkie-talkie device to be manufactured with a mobile phone-like structure, making it smaller and easier to hold. Furthermore, due to its smaller functionality, the manufacturing cost can be lower, improving ease of use and applicability.

[0035] The circuit board also includes a Bluetooth module. In addition to the SIM card and Wi-Fi module, the Bluetooth module enables wireless data calls and data transmission. Therefore, all three wireless modes can achieve voice calls or data transmission (such as system upgrades). The Wi-Fi and Bluetooth modules can be directly integrated onto the circuit board or directly onto the wireless transceiver module.

[0036] The volume control button 9 is located below the PTT button 8. The volume control button 9 includes an up button and a down button, with the up button located above the down button.

[0037] Since the PTT button is used most frequently, and given the typical hand gripping the casing with fingers moving from bottom to top, placing it above the volume control button prevents accidental volume control presses when using the PTT button for intercom, ensuring ease of use and comfort.

[0038] See Figure 2 , 4 The right side of the housing 1 is provided with an input interface 14 and a headphone jack 15, which are electrically connected to the circuit board 2. The headphone jack is used to plug in headphones, preventing the speaker from emitting sound and allowing the sound to be emitted through the headphones. The input interface can be used to connect the intercom device to external data, such as a Type-C interface, for example, for system upgrades of the intercom device (in the attached diagram, the input interface and headphone jack have dustproof protective covers).

[0039] See Figure 1 , 2 As shown in Figures 4 and 5, a defined button 16 is also provided on the top of the housing 1, and a button element is provided on the circuit board 2 corresponding to the defined button 16 (the button element is provided on the circuit board so that when the corresponding button is pressed, the signal is transmitted to the circuit board through the button element to realize the corresponding function).

[0040] An indicator light 17 is also provided on the top of the housing 1, and the indicator light 17 is electrically connected to the circuit board 2. The illumination of the indicator light can indicate the working status of the intercom device, and it can also make it easier to find the intercom device, especially at night.

[0041] The button can be defined as either an SOS button or a power button. If it is an SOS button, the user can press it to make an emergency call in case of an emergency. If it is a power button, the intercom device can be turned on and off using the power button.

[0042] Referring to Figures 2 and 3, a hook structure 18 is provided on the rear end side of the housing 1. In this embodiment, the hook structure is a T-shaped structure, which includes an integral connecting post 19 and a hanging post 20. The hanging post is located at the outer edge of the rear end of the connecting post, and the outer diameter of the hanging post is larger than the outer diameter of the connecting post. A stepped through hole is provided in the middle of the hook, and a bolt passes through the stepped through hole to connect with the housing. When the intercom device needs to be hooked, it is directly hooked into a bayonet through the connecting post and the hanging post. The width of the bayonet is smaller than the diameter of the hanging post. Therefore, the hooking of the intercom device is achieved by using the hanging post for limiting.

[0043] See Figure 3 , 4 As shown in Figures 6 and 7, the display assembly 4 includes a fixed bracket 21, a display screen 22, and a protective panel 23. The front end of the housing 1 has an installation window 24 communicating with the interior of the housing 1, and the protective panel 23 is installed on the installation window 24. The display screen 22 and the fixed bracket 21 are disposed inside the housing 1. The display screen 22 is disposed on the front side of the fixed bracket 21. The front side of the fixed bracket 21 has a receiving groove 25, and the display screen 22 is disposed in the receiving groove 25. The rear end of the fixed bracket 21 is snapped into connection with the circuit board 2.

[0044] In this embodiment, the protective panel is a transparent panel, such as glass or a transparent plastic sheet. The display screen is placed directly in the receiving slot, and the top, bottom, left, and right sides of the display screen are limited by the receiving slot. A connecting slot is provided on the fixing bracket, and the display screen's circuitry passes through the connecting slot to connect with the circuit board. Alternatively, the side wall of the fixing bracket has a notch that communicates with the receiving slot, and the display screen's circuitry passes through the notch to connect with the circuit board (the connecting slot and notch also provide some heat dissipation space for the display screen). The rear end of the display screen is limited by the fixing bracket. More preferably, the outer edge of the front end of the display screen abuts against the inner rear wall of the outer edge of the mounting window. The front inner wall of the housing limits the display screen, and the rear end is limited by the fixing bracket, thereby achieving rapid fixation of the display screen. The fixing bracket and the circuit board snap together, enabling rapid assembly of the display screen. Meanwhile, in this utility model, since the intercom device generates heat during operation, the heat is mainly generated by the components on the display screen and the circuit board (the components on the circuit board generate more heat). Therefore, the presence of the fixed bracket can also separate the display screen and the circuit board, so that the heat generated by the two will be isolated from each other, which will not affect the normal display of the display screen, and the heat generated by the display screen will not be directly transferred to the circuit board, thus preventing further aggravation of the high temperature of the circuit board, ensuring the stability of the circuit board, extending its service life, and reducing the maintenance rate.

[0045] See Figure 6 , 7As shown, two elastic buckles 26 are symmetrically arranged on the rear end face of the fixed bracket 21, and the circuit board 2 is provided with a slot 27 that cooperates with the elastic buckles 26. The fixed bracket 21 is connected to the circuit board 2 by the elastic buckles 26 and the slot 27.

[0046] In this embodiment, the opening of the elastic buckle allows for quick engagement with the circuit board when connecting the mounting bracket and the circuit board. The elastic buckle is directly aligned with the slot, and the mounting bracket is pressed backward. As the elastic buckle inserts into the slot, its rear end deforms and passes through the slot, then automatically returns to its original position, achieving a quick engagement with the circuit board. For disassembly, the elastic buckle is pried open from the rear end of the circuit board, and then pushed forward to disengage it from the slot, allowing for rapid removal of the mounting bracket and the circuit board.

[0047] See Figure 6 , 7 As shown, the rear side of the fixed bracket 21 is also provided with at least two support columns 28. The rear end of the support column 28 is provided with a positioning column 29 coaxially arranged. The rear end diameter of the positioning column 29 is smaller than the front end diameter of the positioning column 29. The circuit board 2 is provided with a positioning hole 30 facing the positioning column 29. Each positioning column 29 is inserted into a positioning hole 30, and the rear end face of the support column 28 abuts against the front end face of the circuit board 2.

[0048] Furthermore, to ensure sufficient spacing between the mounting bracket and the circuit board, allowing for the placement of components and providing adequate space for heat dissipation, support columns are incorporated. These columns separate the bracket from the circuit board, and their contact with the board allows the elastic clips to engage, ensuring a secure connection. To prevent misalignment, positioning columns and holes are added for precise positioning of the bracket and circuit board during connection. The positioning columns, with their tapered shape (smaller diameter at the rear than the front), also serve as guides, facilitating quick connection between the bracket and the circuit board.

[0049] More preferably, the mounting bracket can be made of metal, which can also conduct heat and increase the heat dissipation area, thereby improving the heat dissipation effect, extending the heat dissipation effect of the circuit board, electronic components on the circuit board, and display screen, extending the service life, and reducing the maintenance rate.

[0050] See Figure 4 , 5As shown in Figure 7, a rearwardly extending support plate 31 is also provided on the upper rear side of the fixed bracket 21. The support plate 31 is located above the circuit board 2, and the wireless transceiver module 12 is installed on the top surface of the support plate 31.

[0051] The tray is used for the installation and support of the wireless transceiver module. In this embodiment, the fixed bracket is connected to the upper part of the circuit board, and its top is set near the top of the inside of the housing. The battery is set near the bottom of the inside of the housing. The wireless transceiver module is placed on the tray, that is, the wireless transceiver module is set at the top of the inside of the housing. This facilitates the reception and transmission of wireless signals and minimizes the influence of electronic components on the circuit board and other components inside the housing, ensuring the stability and strength of the signal. At the same time, it eliminates the need for a separate antenna, making it more aesthetically pleasing.

[0052] See Figures 1-5 As shown, the housing 1 includes a front housing 32 and a rear housing 33. The outer edge of the rear end of the front housing 32 contacts the outer edge of the front end of the front housing 32, and the front housing 32 and the rear housing 33 are connected by bolts.

[0053] The housing adopts a two-piece structure for easy assembly of the intercom equipment. Multiple hollow connecting posts 34 are installed on the inner wall of the rear housing, and studs 35 are installed on the inner wall of the front housing, directly opposite the connecting posts. Bolts pass through the connecting posts and studs from the rear side of the rear housing to secure the front and rear housings. More preferably, a sealing ring is installed at the contact point between the front and rear housings to enhance waterproofing.

[0054] Anti-slip texture is set on the back of the back cover to increase the anti-slip effect and improve the user's grip.

[0055] Meanwhile, this utility model is easier to assemble. The corresponding buttons and housings are assembled, the display screen assembly and circuit board are assembled, and then the front and rear housings are assembled, making the assembly process simpler.

In the description of the invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0057] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. For instance, the two components can be mechanically connected by contact or abutting; they can also be directly hooked or connected by an intermediate medium; or they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
