[0002] At present, new technologies for car interiors are widely used, and on-board displays are a must for all cars. Some models have multiple large-size displays, resulting in a large reduction in physical buttons, and some models do not even have physical buttons. Although the display screens provide users with a strong visual impact and a sense of technology, they also bring a lot of inconvenience in operation. The existing touch screen display screens do not have obvious anti-mistouch functions and touch sensing functions, which can easily cause misoperation during operation. Passengers cannot sense whether the trigger is completed effectively, which can easily distract the driver's attention during driving and cause complete risks. Summary of the invention

When a certain function is needed, the corresponding button on the display frame is pressed to deform it toward the display screen, driving the conductive rubber to deform, so that the conductive part on the conductive rubber contacts the display screen, and the touch threshold of the display screen is changed. After the circuit board assembly inside the display screen recognizes the change in the threshold here, it triggers the realization of the corresponding function, which is finally reflected on the display screen. The mechanical button has a certain operation formation, so that the user can clearly perceive the completion of the operation and the triggering of the function, reducing the safety risks caused by operating the touch function of the display screen during driving.

[0007] With the above further arrangement, the structure between the display frame and the display screen is firm, and magnetic installation is adopted, which makes disassembly easy.

[0008] The utility model is further configured as follows: mounting grooves are provided at both ends of the display frame, first magnets are installed in the mounting grooves, and second magnets are correspondingly provided on the inner side of the display screen, and the mechanical button assembly is installed when the first magnet and the second magnet are attracted.

[0009] The above further configuration has a simple structure and is easy to assemble and disassemble. The two magnets are attracted to each other at different levels, and the magnets can find their positions by self-tapping and are fixed by mutual attraction.

[0010] The utility model is further configured that: each conductive part is brushed with carbon powder.

[0011] By adopting the above-mentioned further configuration, the conductive effect is good, and it is easy to contact with the display screen, thereby affecting the capacitance threshold of the display screen to realize the triggering of the function.

[0012] The present invention is further configured as follows: a first receiving groove is provided on the upper end surface of the display surface frame, each through hole is located at the bottom of the first receiving groove, and the conductive rubber is pasted in the first receiving groove.

[0013] By adopting the above further arrangement, the structure is compact, so that the conductive rubber structure is firm and deforms downward to generate displacement under the drive of the key.

[0014] The present invention is further configured as follows: a second receiving groove is provided on the display frame at the periphery of the first receiving groove, the display panel is also configured in a "U" shape, and the display panel is pasted in the second receiving groove.
