Car navigation plastic bezel

1. Protecting the navigation: The plastic bezel can protect the navigation touchscreen, preventing the touchscreen from being subjected to external physical damage1.

2. Providing mounting points: The plastic bezel provides points for installing the navigation touchscreen on the vehicle, i.e., the navigation touchscreen is mounted on the plastic bezel, and the plastic bezel is then mounted on the vehicle.

3. Solving material difference issues: Since the surface of the touchscreen is glass and the plastic bezel is plastic, the two materials are different and have different rates at high temperatures, which can cause the edges of the plastic bezel to crack. Therefore, a gap assembly is adopted between the navigation touchscreen and the plastic bezel to this problem1.

4. Ensuring uniform assembly gap: By setting up a protruding structure and utilizing the principle that point contact is easier to manufacture and control than contact, the problem of uneven gaps around the touchscreen and the plastic bezel is solved. This problem arises because the navigation touchscreen and the plastic bezel have different materials and shrinkage, and after high-temperature shrinkage, the edges of the navigation touchscreen cannot fully contact the plastic bezel.

Car navigation wiring harness

The function of the automotive navigation wiring harness is to connect the power supply with electrical appliances and switches, and to ensure the reliable passage current. The automotive navigation wiring harness is the main body of the automotive electrical network, and its main function is to connect the power supply with electrical appliances and switches ensuring the reliable transmission of current. The design principle of the automotive wiring harness aims to correctly connect all electrical equipment on the vehicle to the automotive power supply through wires,, relays, switches, and control devices, so as to ensure the normal operation of each electrical device. The application scope of the automotive wiring harness is very wide including automotive high-voltage wiring harness testing, high-voltage connector testing, high-voltage battery testing, inverter testing, air conditioning compressor testing, generator testing, electric motor, driver wiring board testing (new energy vehicle soft board), AC charging gun testing, and AC charging socket testing. The design principle and application of the automotive wiring harness a crucial part of the automotive electrical circuit. By correctly connecting each electrical device, the normal operation of the automotive electrical circuit can be guaranteed, and the performance and of the vehicle can be improved.
