A vehicle electronic device

Abstract

The invention relates to an elastic screen pressing bracket and a vehicle-mounted electronic device using the same. It provides an elastic screen-pressing bracket, by setting a first board, a first hook and a second hook on the elastic screen-pressing bracket, which can be in conflict with the panel, the TFT screen and the PCB board assembly at the same time, thereby forming multiple The balance between these forces can not only stably install the elastic pressure screen bracket, but also make it take into account the functions of fixing the TFT screen and outputting static electricity at the same time. The invention also provides a vehicle-mounted electronic device using the elastic pressure-screen bracket. The elastic screen pressing bracket of the present invention can be integrally formed, has simple structure, ingenious design, and is easy to assemble and disassemble, and can be used for TFT screen installation of various equipment such as vehicle-mounted electronic devices.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted electronic equipment, in particular to an elastic pressure screen bracket and a vehicle-mounted electronic device using the same. Background technique [0002] In the design and development of on-board electronic products, in order to realize intelligent unified operation, most of the multimedia devices adopt TFT screen touch. At present, in vehicle-mounted products, the fastening methods of the TFT screen mainly include the following types: 1. Tighten and press the screen bracket with screws to fix the TFT screen on the front shell; 2. Use the back cover to directly fix the TFT screen 3. Use a combination of screws and washers near the edge of the TFT screen to fix it; the above methods all need to rely on the fastening of screws to fix the TFT screen. As we all know, screws are prone to aging and slippage. Teeth, which will directly affect the stability of the installation, thus affecti...

At present, in vehicle-mounted products, the fastening methods of the TFT screen mainly include the following types: 1. Tighten and press the screen bracket with screws to fix the TFT screen on the front shell; 2. Use the back cover to directly fix the TFT screen 3. Use a combination of screws and washers near the edge of the TFT screen to fix it; the above methods all need to rely on the fastening of screws to fix the TFT screen. As we all know, screws are prone to aging and slippage. Teeth, this will directly affect the stability of the installation, thereby affecting the stability of the vehicle-mounted product

In addition, in the current vehicle electronic products, the grounding methods of the TFT screen mainly include the following: 1. Use conductive sponge to make it contact with the TFT screen and PCB board at the same time; 2. Use metal elasticity to make it contact with the TFT screen and PCB board contact; in the above methods, the parts used for grounding exist alone. If it is firmly fixed, it needs to cooperate with related structural design or use screw locking, which not only increases the cost of parts, but also increases the difficulty of assembly. Aging is also prone to have a direct effect on electrostatic output
