[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 4 As shown, a vehicle-mounted display device 10 is provided, including: a top plate 100, an upper shell 200, a PCB board 300, a magnetic component 500, and a plastic lower shell 400; the top plate 100 is connected to one end of the upper shell 200, the PCB board 300 is disposed inside the upper shell 200, the plastic lower shell 400 is connected to the other end of the upper shell 200, and the magnetic component 500 is connected to the plastic lower shell 400.

[0034] Specifically, the top plate 100 is connected to the top of the upper shell 200. The upper shell 200 is made of engineering plastic, possessing a certain strength and toughness, providing structural support for the entire vehicle display device 10. Furthermore, the outer surface of the upper shell 200 has an anti-slip texture to improve grip and operational stability. The upper shell 200 is a ring-shaped frame with a hollow lower end to accommodate electronic components such as the PCB board 300. The PCB board 300 is installed inside the bottom of the upper shell 200. The PCB board 300 integrates core electronic components such as a display driver chip, power management chip, and signal processing chip. The PCB board 300 is fixed to the support pillars inside the upper shell 200 with screws to ensure that it will not shift during use. The plastic lower shell 400 matches the shape of the upper shell 200 and is tightly connected to the bottom of the upper shell 200, forming a sealed space. The plastic lower shell 400 is made of ABS engineering plastic, possessing good heat resistance and mechanical strength. The outer surface of the magnetic component 500 is connected to the inner surface of the plastic lower shell 400.

[0035] It is worth noting that by employing a magnetic component 500 connected to the plastic lower shell 400 in the vehicle display device 10, the display device can be magnetically fixed to the vehicle bracket or metal center console, replacing the traditional screw connection method. This effectively solves the problem of device loosening caused by vehicle vibration during long-term use. Simultaneously, the magnetic connection method simplifies the assembly process and supports quick disassembly and maintenance. For example, when replacing the PCB board 300 or other components, the operation can be completed without complex disassembly tools. Therefore, the structural design of the vehicle display device in this application improves stability, extends service life, and makes it more convenient for users.

[0036] To facilitate the installation of magnetic component 500, such as Figures 2 to 4 As shown, in some embodiments, the plastic lower shell 400 is provided with an embedding and receiving structure 410, and the magnetic component 500 is provided with an embedding block 510 that cooperates with the embedding and receiving structure 410. The embedding block 510 is snapped into the embedding and receiving structure 410 to connect the magnetic component 500 to the plastic lower shell 400.

[0037] Specifically, the plastic lower shell 400 is hollow, and an inwardly facing embedding and receiving structure 410 is provided in the middle of the plastic lower shell 400. The magnetic component 500 is a rubber magnet, and is disc-shaped. Rubber magnets are soft magnetic materials made by mixing magnetic powder with rubber, and have the characteristics of good flexibility and easy processing. The size and shape of the magnetic component 500 are adapted to the internal size and shape of the plastic lower shell 400, and an embedding block 510 that cooperates with the embedding and receiving structure 410 is provided on the outer surface of the magnetic component 500, so that the magnetic component 500 can be embedded and installed in the plastic lower shell 400. This connection method ensures a stable connection between the magnetic component 500 and the plastic lower shell 400, preventing loosening during use.

[0038] In another embodiment, when the magnetic component 500 is embedded in the plastic lower shell 400, the surface of the embedded block 510 is covered with a rubber layer, which can effectively prevent scratches and improve the product's service life and user experience.

[0039] In another embodiment, the plastic lower shell 400 is configured as a shell with a closed lower end, and the bottom end of the plastic lower shell 400 is recessed with a receiving structure. The magnetic component 500 includes a magnetic ring and a decorative piece, which are sequentially embedded in the receiving structure.

[0040] Specifically, the magnetic component 500 is configured as a magnetic ring, which is made of ferrite material and has good magnetic permeability and magnetic flux density. A decorative piece is used to cover the magnetic ring on the lower end of the plastic lower shell 400, concealing it without affecting its magnetism and making the display device more aesthetically pleasing. Furthermore, it is understandable that the material and structural design of the magnetic ring, compared to rubber magnets, is more conducive to controlling the range and distribution of the magnetic field, reducing electromagnetic interference to the internal circuitry of the vehicle display device 10, improving overall electromagnetic compatibility, and ensuring the stability of display, interactive, and other functions.

[0041] To facilitate the connection between the plastic lower shell 400 and the PCB board 300, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, a limiting post 430 is provided on the inner surface of the plastic lower shell 400, and a positioning sleeve (not shown) is provided on the PCB board 300, which is engaged with the limiting post 430.

[0042] Specifically, the positioning sleeve and the limiting post 430 work together to further enhance the fixing stability between the PCB board 300 and the plastic lower shell 400, preventing the PCB board 300 from shifting during use and affecting the display effect.

[0043] In addition, pins are provided on the bottom surface of the PCB board 300, and a limiting hole is provided on the plastic lower shell 400. The limiting hole penetrates the bottom surface of the plastic lower shell 400, so that the pins can protrude from the bottom surface of the plastic lower shell 400 and can be connected and contacted with other automotive display-related components.

[0044] To facilitate the connection between the lower plastic shell 400 and the upper shell 200, such as Figure 2 and Figure 4 As shown, in some embodiments, a slot 420 is provided on the outer surface of the lower plastic shell 400, and a snap-fit ​​block 210 that cooperates with the slot 420 is provided on the inner surface of the upper shell 200. The snap-fit ​​block 210 snaps into the side wall of the slot 420.

[0045] Specifically, a rectangular slot 420 is formed on the outer surface of the lower plastic shell 400, and a snap-fit ​​block 210 protrudes inward on the inner surface of the upper shell 200. The lower plastic shell 400 is connected to the upper shell 200 through the engagement of the snap-fit ​​block 210 and the slot 420. This ensures a secure connection between the upper shell 200 and the lower plastic shell 400, preventing loosening during use.

[0046] To facilitate the installation of the top plate 100 and the upper shell 200, such as Figures 1 to 4 As shown, in some embodiments, the upper shell 200 is recessed and has an installation structure 220, and the top plate 100 is disposed within the installation structure 220.

[0047] Specifically, the top of the upper shell 200 is recessed downwards, with a mounting structure 220. The dimensions of the top plate 100 match those of the mounting structure 220, allowing the top plate 100 to be mounted on the top of the upper shell 200 and securely bonded with adhesive, thus ensuring a more stable connection between the top plate 100 and the upper shell 200. Furthermore, the top surface of the top plate 100 is flush with the top surface of the upper shell 200, improving the overall aesthetics. Simultaneously, the mounting structure 220 prevents the top plate 100 from shifting during installation, improving installation accuracy.

[0048] To facilitate the use of the display device, such as Figures 1 to 4 As shown, in some embodiments, the upper shell 200 has multiple heat dissipation holes 230.

[0049] Specifically, heat dissipation holes 230 are evenly distributed around the periphery of the upper shell 200 to enhance the heat dissipation effect of the display device. These heat dissipation holes 230 can form air convection, effectively removing the heat generated by the PCB board 300 during operation and preventing the internal temperature of the device from being too high and affecting the normal operation of electronic components.

[0050] To enhance the usability of the display device, such as Figures 2 to 4 As shown, in some embodiments, the vehicle display device 10 further includes a receiving induction coil 600, which is disposed between the PCB board 300 and the plastic lower shell 400.

[0051] Specifically, the receiving induction coil 600 is made of copper wire and is used to receive electromagnetic signals emitted by an external wireless charging device, converting electromagnetic energy into electrical energy to provide power support for the vehicle display device 10.

[0052] To facilitate heat dissipation of the device, such as Figure 1 and Figure 5 As shown, in some embodiments, the vehicle display device 10 further includes a heat sink 700, which includes a housing 710 and heat sink fins 720. The housing 710 is connected to the plastic lower shell 400, and the housing 710 has heat dissipation holes 730. The heat sink fins 720 are disposed inside the housing 710.

[0053] Specifically, the housing 710 is made of aluminum alloy, which has good thermal conductivity. The housing 710 includes a main shell and a heat sink. The top of the main shell is connected to the bottom of the plastic lower shell 400, and the bottom of the main shell is connected to the heat sink. The heat sink has heat dissipation holes 730, which are evenly distributed on the surface of the heat sink. Heat dissipation fins 720 are disposed inside the housing 710 and are also made of aluminum alloy. The heat dissipation fins 720 can quickly conduct heat from the plastic lower shell 400 to the outside of the heat sink 700, preventing the device from overheating.

[0054] To enhance the usability of the device, in some embodiments, the top plate 100 is configured as a glass panel.

[0055] Specifically, the top panel 100 is made of glass, which has good light transmittance and wear resistance, ensuring display quality while extending the device's lifespan. Furthermore, the top panel 100 can integrate a touch sensor to support touch control; that is, the glass panel is bonded to the touch sensor, such as a capacitive touch sensor, thereby enabling human-computer interaction.

[0056] Furthermore, the vehicle display device 10 of this application also includes other conventional components, such as a Bluetooth sensing system, a button switch, a charging structure, a memory card placement structure, etc. The specific structure and operation of these components are known to those skilled in the art and are feasible, and will not be described in detail in this embodiment.

[0057] The specific structure and operation of the display driver chip, power management chip, and signal processing chip, as well as the positioning, installation, and operation of the receiving induction coil 600, are known to those skilled in the art and are achievable, and will not be described in detail in this embodiment.
