[0020] This utility model discloses a car navigation device.

[0021] like Figures 1 to 7 As shown, the car navigation system includes an LCD screen 10, a front shell 20, a rear shell 30, a base 40, and a main board 50. The LCD screen 10 is electrically connected to the main board 50. The LCD screen 10 is mounted on the front shell 20, the front shell 20 is mounted on the rear shell 30, and the rear shell 30 is mounted on the base 40. The LCD screen 10, the front shell 20, the rear shell 30, and the base 40 are all circular. The base 40 includes a plug 41 and a slot 42. The rear shell 30 is provided with a plug 31 that mates with the slot 42. The base 40 is mounted on the vehicle body via the plug 41.

[0022] This car navigation system is easy to install. By dividing the system into core modules such as an LCD screen, front shell, rear shell, base, and motherboard, it achieves modularity, simplifying production, assembly, and maintenance. Each component can be manufactured and replaced independently, reducing costs. Furthermore, the LCD screen, front shell, rear shell, and base are all circular. This not only gives the product a unique and harmonious aesthetic appearance, allowing it to better integrate into the streamlined and cohesive interior design of modern cars, but more importantly, the circular structure facilitates the circular layout of internal wiring and components, optimizing interior space utilization. Moreover, the base features specially designed insertion posts and slots. The slots cooperate with the insertion posts on the rear shell to form a reliable mechanical connection system. This structure ensures that the rear shell of the car navigation system can be quickly and accurately aligned and locked onto the base, achieving a "quick-release" installation experience. Simultaneously, the base is independently mounted to the vehicle body via insertion posts, achieving a rigid connection with the vehicle body, ensuring the stability and shock resistance of the entire device during driving, and effectively preventing loosening and abnormal noises.

[0023] The front cover 20 is equipped with an ambient light panel 60 and a matching light strip 70, both of which are arc-shaped. By incorporating the ambient light panel 60, the color can be changed according to user preferences or driving modes, greatly enhancing the technological feel and luxurious atmosphere of the vehicle interior, and meeting users' needs for personalized and emotional design. The ambient light panel 60 and light strip 70 adopt the same arc shape as the car navigation system's casing, ensuring that the light is evenly and continuously emitted, avoiding light breaks or uneven brightness caused by shape mismatch. This creates a perfect aesthetic and functional unity with the circular navigation system body, further enhancing the product's overall sense of completeness and high-end feel.

[0024] Among them, a microphone reset plate 80 is installed between the front shell 20 and the rear shell 30, and the microphone reset plate 80 is electrically connected to the main board 50; the microphone reset plate 80 is provided with a reset switch 81 and a microphone 82, the LCD screen 10 and the front shell 20 are both provided with switch holes that cooperate with the reset switch 81, and the LCD screen 10 and the front shell 20 are both provided with microphone holes that cooperate with the microphone 82.

[0025] The reset switch 81 and microphone 82 are integrated onto a single microphone reset plate 80, which connects the front housing 20 and the rear housing 30. This modular integration simplifies the internal structure of the car navigation system, reduces the number of parts and assembly steps, and improves production efficiency and product reliability. Corresponding switch holes and microphone holes are provided on both the LCD screen 10 and the front housing 20, ensuring that users can operate the reset switch 81 without obstruction and that the microphone 82's sound pickup is not blocked by the structure. This dual-hole design also serves to position and protect the internal precision components, preventing misalignment or damage during assembly or use.

[0026] The slots 42 are evenly distributed on the base 40. The even distribution of the slots 42 on the base 40 allows the locking pins 31 on the rear shell 30 to apply a uniform locking force, thereby avoiding local wear or structural fatigue caused by stress concentration. This greatly enhances the firmness of the connection between the base 40 and the rear shell 30 and the reliability of long-term use, especially under the bumpy and vibrating environment of the vehicle.

[0027] The base 40 has a button hole 43, and a button hole plug 44 is installed in the button hole 43. The button hole plug 44 can effectively prevent dust, moisture and other contaminants from entering the car navigation system, protect the motherboard 50 and other precision electronic components from corrosion, and improve the product's environmental adaptability and service life. At the same time, it also avoids the risk of users or foreign objects accidentally touching internal live components, thus enhancing safety.

[0028] Furthermore, the button hole plug 44 includes a first pin 441 and a second pin 442, which are detachably connected to the base 40 via the first pin 441 and the second pin 442. The dual-pin structure of the button hole plug 44 provides a stable and secure connection, preventing the button hole plug 44 from falling off during normal vibration. At the same time, the detachable connection design also facilitates later maintenance (such as adjustments via the button hole 43).

[0029] The motherboard 50 is connected to a heat sink 90, the base 40 is provided with a first hollowed-out groove 45 to cooperate with the heat sink 90, the rear shell 30 is provided with a second hollowed-out groove 32 to cooperate with the heat sink 90, and the front shell 20 is provided with a limiting frame 21 to cooperate with the heat sink 90.

[0030] By connecting an independent heatsink 90 to the motherboard 50, active cooling is achieved, which can quickly dissipate the large amount of heat generated by the motherboard 50 (especially the main control chip) during operation. This effectively prevents system throttling, stuttering, or even component damage caused by overheating, ensuring the stability and performance of the navigator under long-term high-load operation. Furthermore, by setting a limiting frame 21, a second hollowed-out groove 32, and a first hollowed-out groove 45 on the front shell 20, rear shell 30, and base 40 respectively, a three-dimensional heat dissipation channel is constructed. Cool air can enter from the first hollowed-out groove 45 at the bottom, flow through the heatsink 90, carry away the heat, and then be discharged from the second hollowed-out groove 32 at the top, forming a highly efficient "chimney effect" and greatly improving the overall heat dissipation efficiency.

[0031] The motherboard 50 is provided with mounting holes and positioning holes, and the motherboard 50 is installed inside the limit frame 21 through the mounting holes and positioning holes.

[0032] The motherboard 50 is mounted inside the limiting frame 21 of the front cover 20 via mounting holes and positioning holes. The mounting holes are used to achieve a rigid connection of fasteners such as bolts, ensuring that the motherboard 50 is fixed in place; while the positioning holes enable quick and accurate pre-positioning of the motherboard in the early stages of assembly, preventing misalignment and improving assembly efficiency and accuracy. The limiting frame 21 itself also provides a protective enclosure for the motherboard 50, enhancing its resistance to vibration and impact.

[0033] The limiting frame 21 has a fixing plate 22 mounted on its edge, and the heat sink 90 is connected to the fixing plate 22. Mounting the fixing plate 22 on the edge of the limiting frame 21 and connecting the heat sink 90 to it provides the heat sink 90 with an independent and robust mounting base. This design avoids directly applying the weight and fixing stress of the heat sink 90 to the solder joints of the motherboard 50, protecting the motherboard 50 and ensuring stable and uniform contact pressure between the heat sink 90 and the motherboard 50 chips, thus guaranteeing long-term effective heat conduction.

[0034] Furthermore, the fixing plate 22 includes a first fixing plate 221 and a second fixing plate 222, with the heat sink 90 installed between the first fixing plate 221 and the second fixing plate 222. By specifying the fixing plate 22 as the first fixing plate 221 and the second fixing plate 222, and installing the heat sink 90 between them, a "clamping" type fixing structure is formed. This design can distribute the clamping force more evenly, ensuring the heat sink 90 is firmly fixed without any room for movement, further improving the connection reliability and the stability of the heat dissipation contact surface under harsh vibration environments.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
