[0002] With the continuous upgrading of motorcycle electronic configurations, the degree of electronic control of motorcycles is becoming higher and higher. Multifunctional, high-precision, high-sensitivity, and intuitive reading electronic digital display and image display LCD instruments are increasingly being used in motorcycles. Further development of intelligent instruments will enhance the level of digitalization, intelligence and integration of the industry. For vehicle manufacturers, the generalization and platformization of controllers will greatly reduce development and management costs.

[0003] A search revealed that Chinese utility model patent application CN202321807142.X discloses a liquid crystal instrument panel and a motorcycle. The liquid crystal instrument panel provided in this application includes a frame, a liquid crystal display module, and a sunshade. A fixing part is provided at the edge of the frame, and the frame forms an observation window. The fixing part is located at the edge of the observation window. The sunshade is disposed within the space enclosed by the frame. The liquid crystal display module includes a glass cover assembly and liquid crystal material encapsulated within the glass cover assembly. The glass cover assembly covers the side of the sunshade facing the observation window, and the edge of the glass cover assembly protrudes from the sunshade and overlaps the fixing part. In this application, the liquid crystal display module of the liquid crystal instrument panel extends beyond the edge of the sunshade and is directly mounted on the fixing part of the frame. The instrument information displayed by the liquid crystal display module can be directly observed without the need for additional glass lenses bonded to the glass cover assembly, reducing the weight of the liquid crystal instrument panel, conforming to the lightweight design concept, and also reducing production costs.

[0004] For example, Chinese utility model patent application number CN202322280903.7 discloses an FPC LCD screen motorcycle instrument panel, including an LCD screen connected to an FPC board.

The NFC inductive start circuit, power control circuit, and display interface circuit are all electrically connected to the microcontroller main control circuit, and the LCD screen is electrically connected to the display interface circuit. It can be understood that the instrument body 1 includes an instrument housing. The bottom of the instrument housing has several screw connecting posts 3 and heat dissipation holes 4. The screw connecting posts 3 are used to facilitate the installation of the instrument body 1 on the motorcycle, and the heat dissipation holes 4 are used for internal heat dissipation of the instrument body 1.
