Abstract

The utility model discloses a connecting device of a display module, which comprises the display module, a PCB board and screw nails. The connecting device of the display module is characterized in that the display module is fixed on the PCB board through a mounting support. Because of utilizing the above devices, the connecting device has the function of connecting the display module and the PCB plate, because of utilizing a semi-'H'-shaped structure, the shock resistance of the display module is increased, and because of a rectangular edge-folding structure the production efficiency is increased.

Description

A kind of coupling arrangement of display module

Technical field

The utility model relates to vehicle electric field, particularly a kind of coupling arrangement of display module.

Background technology

Automobile combination meter is an important safety member in automobile, and it is the main parts that the driver obtains motoring condition information.At present, flourish along with the automobile instrument cause, there has been increasing automobile instrument to adopt big regional liquid crystal display display module, the used LCD of common combination instrument normally PIN pin or conductive rubber slice is connected on the meter body pcb board, but for the LCD display module, at first its volume is than next big many of single LCD, secondly because its backlight has been incorporated into inside modules, so on pcb board, just need not place backlight again.Moreover the signal PIN pin number of its output also will be much smaller than the number of common LCDPIN pin.And these differences have just determined us to exist very big difference on common LCD of installation and display module.

Because the singularity of the product of display module own, this has just proposed new requirement to the mechanical assembly structure of gauge internal.It all has extremely strict requirement to other a series of mechanical propertys such as anti-vibration, crashworthinesses, simultaneously display screen with the process of instrument installation or removal in also exist some specific technological requirement.

Providing a kind of novel coupling arrangement to be used for display module, to be connected to the automobile instrument body be the prior art technical issues that need to address.

The utility model content

Technical problem to be solved in the utility model is that the coupling arrangement that a kind of display module is provided is to reach the purpose that connects display module and automobile instrument body.

For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of coupling arrangement of display module, comprise display module, pcb board, screw, it is characterized in that: described display module is fixed on the pcb board by mounting bracket, to reach display module is fixed to purpose on the pcb board.

A kind of coupling arrangement of display module, described mounting bracket are half of " worker " word structure, and mounting bracket is half of to be connected with display module, and one side of something is connected with pcb board in addition; Be equipped with the rectangle flanging perpendicular on the both sides of mounting bracket, so that in the process of installing, play the effect of location earlier with its two sides.

A kind of coupling arrangement of display module, four jiaos of described pcb board are respectively equipped with a flanging patchhole and a pilot hole, and its position is corresponding with rectangle flanging, the pilot hole of mounting bracket, to reach the purpose that pcb board and mounting bracket fix.

A kind of coupling arrangement of display module, four jiaos of described display module bottom surface are respectively equipped with a flanging patchhole and a pilot hole, its position is corresponding with rectangle flanging, the pilot hole of mounting bracket, to reach the purpose that display module and mounting bracket fix.

A kind of coupling arrangement of display module, described mounting bracket, display module, pcb board interfix by screw respectively.

A kind of coupling arrangement of display module, owing to adopt said apparatus, this device plays the effect that connects display module and pcb board, owing to adopt half " worker " word structure, improves in the antidetonation energy of display module, adopts rectangle flanging structure to enhance productivity.

Embodiment

As shown in Figure 1, a kind of coupling arrangement of display module comprises display module 1, pcb board 3, screw 4, it is characterized in that: described display module 1 is fixed on the pcb board 3 by mounting bracket 2, to reach display module is fixed to purpose on the pcb board.

A kind of primary structure of coupling arrangement of display module is made of mounting bracket 2 and screw 4, and screw 4 is separately fixed at mounting bracket 2 on display module 1 and the pcb board 3, thereby reaches display module 1 and the fixing purpose of meter body.

As shown in Figure 2, mounting bracket 2 is the shape of half of " worker " word, and its both sides are connected with pcb board 3 with display module 1 respectively; The purpose of doing like this is in order to play suitable damping effect, to have increased the elasticity of display module 1 when high vibration, thus prevent display module 1 should be rigidity excessive when high vibration the extruding screen cause the breakage of screen.

As shown in Figure 3, near the pilot hole 6 of mounting bracket 2 and pcb board 3 and display module 1 bending several rectangle flangings 7, this structure can have a first location process before display module 1 and pcb board 3 assemble, and then carried out the installation of screw 4.Thereby having avoided will spending in the production assembling process a large amount of time makes support screwing hole and the position that is mounted the screw hole of part coincide, and influences production efficiency.

As shown in Figure 4, be respectively equipped with a flanging patchhole 7 and a pilot hole 6 at display module 1 bottom four jiaos, its position is corresponding with rectangle flanging 5, the pilot hole 6 of mounting bracket 2, to reach the purpose that display module and mounting bracket fix.

As shown in Figure 5, be respectively equipped with a flanging patchhole 7 and a pilot hole 6 at pcb board 3 four jiaos, its position is corresponding with rectangle flanging 5, the pilot hole 6 of mounting bracket 2, to reach the purpose that pcb board and mounting bracket fix.

In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
