[0006] In the above scheme: there are two positioning pins, which are respectively located in the left and right halves of the instrument, so as to improve the positioning effect and avoid the display misalignment caused by installation offset.

[0007] In the above scheme: the two positioning pins and the middle threaded hole column are distributed in a triangular structure, and the structure is stable.

[0008] In the above solution: the middle part of the rear shell is arranged to protrude backwards, and the length of the middle threaded hole column is longer than the installation threaded hole column.

[0009] In the above scheme: the bracket is provided with a wiring hole near the bottom, and the wiring of the VA screen assembly passes through the wiring hole and is connected to the PCB board to meet the installation requirements.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are: not only can it display various vehicle information when the vehicle is driving, but the set NFC module can start the instrument and the car computer through the NFC module induction, and the functions are diverse. The set card slot and the installation threaded hole column can be pre-positioned through the card slot first, and then fixed by bolts and installation threaded hole columns, and the assembly is fast. The set positioning pin can quickly position the PCB board for installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The above and / or additional aspects and advantages of the present invention will become apparent and easily understood from the description of the embodiments in conjunction with the following drawings, in which:
