It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0025] See also Figure 1-5 , an embodiment provided by the utility model:

[0026] A controller for a central control screen includes a bottom cover 1 and a top cover 2. Two groups of PCB boards 6 are arranged inside the bottom cover 1, and the outer surfaces of the two groups of PCB boards 6 are provided with positioning grooves 912. The inner walls of the bottom cover 1 and the top cover 2 are provided with multiple groups of positioning blocks 911, and the multiple groups of positioning blocks 911 are connected to the positioning grooves 912 through screws. The bottom cover 1 and the top cover 2 are both made of aluminum alloy, and two groups of fixing grooves are opened at the bottom end of the bottom cover 1. Fixing pins 3 are installed in the two groups of fixing grooves, and the top of the fixing pins 3 is connected to the interface component 311.

[0027] Furthermore, the inner wall of the top cover 2 is provided with a snap-fitting groove 9 at each of the four corners, and the outer surface of the snap-fitting groove 9 is provided with a screw hole, and the snap-fitting block 7 at the top of the bottom cover 1 matches the snap-fitting groove 9 on the inner wall of the top cover 2 and is fixed through the screw hole, thereby providing a stable and reliable connection method, so that the bottom cover 1 and the top cover 2 can be tightly combined together, and the stability and strength of the overall structure are enhanced. At the same time, this snap-fitting structure also makes it easier to disassemble the controller during maintenance, improving the convenience of maintenance.

[0028] Furthermore, the four corners of the top of the bottom cover 1 are all fixedly mounted with snap-fit ​​blocks 7 , and screw holes are provided on the outer surface of the snap-fit ​​blocks 7 , so that the snap-fit ​​blocks 7 can quickly connect the bottom cover 1 and the top cover 2 .

[0029] Furthermore, the outer surface of the bottom end of the bottom cover 1 and the two sides of the top cover 2 are serrated, and the serrated outer surface can increase the friction between the controller and the installation position, thereby improving the stability of the controller installation. Even if the vehicle encounters bumps or vibrations during driving, the controller can remain stable and is not easy to loosen or fall off.

[0030] Furthermore, a connection groove is provided on the outer surface of one side of the bottom cover 1 and the top cover 2, and a cover 4 is installed in the connection groove, and a pull groove 5 is provided on the outside of the cover 4. The pull groove 5 on the outside of the cover 4 is convenient for opening, which provides a detachable closed structure, making it convenient for maintenance personnel to open the controller for internal inspection and maintenance operations. At the same time, the existence of the cover 4 can also effectively protect the circuits and components inside the controller, prevent the intrusion of external factors such as dust and moisture, and improve the durability and reliability of the controller.

[0031] Furthermore, a plurality of groups of latches 8 are fixedly mounted on an outer surface of one side of the cover 4 , and the latches 8 are used to realize quick installation of the cover 4 .

[0032] Furthermore, the outer ends of the bottom cover 1 and the surface cover 2 are arc-shaped. The arc-shaped design not only makes the controller more beautiful and elegant in appearance, but also avoids the potential safety hazards caused by sharp corners.

[0033] Working principle: First, the bottom cover 1 and the top cover 2 are the main structural parts of the controller, which are cast with aluminum alloy material, which not only ensures the firmness of the structure, but also has good heat dissipation performance, ensuring that the controller can stably dissipate heat during operation and avoid affecting the performance due to overheating. During the assembly process, the two groups of PCB boards 6 set inside the bottom cover 1 are key components. The outer surface of the PCB board 6 is provided with a positioning groove 912, and the inner wall of the bottom cover 1 and the top cover 2 is provided with a plurality of positioning blocks 911. Through the connection between the screw and the positioning groove 912, the positioning block 911 and the positioning groove 912 are closely matched to achieve the precise fixation of the PCB board 6 in the bottom cover 1. This design not only simplifies the installation steps, but also improves the stability of the PCB board 6, and reduces the risk of loosening or damage caused by vibration or impact. The two groups of fixing grooves opened at the bottom end of the bottom cover 1 are installed with fixing pins 3, and the top end of the fixing pins 3 is connected with an interface component 311. This design enables the controller to be easily connected with other systems of the car to achieve data transmission and reception of control instructions. The snap-fitting grooves 9 at the four corners of the inner wall of the top cover 2 cooperate with the snap-fitting blocks 7 at the four corners of the top of the bottom cover 1, and the bottom cover 1 is fixed with the top cover 2 to achieve a tight connection. This snap-fitting structure not only enhances the overall structural strength of the controller, but also makes it easier to disassemble the controller for maintenance and replacement of parts.
