In designing the step surfaces, the height of the first step surface 21 is smaller than the height of the second step surface 22 adjacent thereto, the height of the second step surface 22 is smaller than the height of the third step surface 23 adjacent thereto, and the connection between the bracket and the different components is achieved by the difference in height between the respective step surfaces, and it should be noted that the height of the step surface referred to in this embodiment refers to the vertical distance between the step surface and the first surface, i.e., the width of each step surface in the bracket shown in fig. 2 in the horizontal direction.
Specifically, the first step surface 21 of the bracket provided in this embodiment is used for fixing between the PCB board and the display module, the second step surface 22 is used for fixing between the bracket body and the back plate of the display module, and the third step surface 23 is used for fixing between the display module and the external base. In fact, after the support is fixed with the back plate of the display module through the second step surface 22, the first step surface 21 and the third step surface 23 are provided to serve as assembly surfaces of the PCB and the base, connection of the support and different components is achieved through step surface design of the support, and connection between the PCB and the base and the display module is achieved by taking the support as an intermediary.
The step surfaces of the support provided in this embodiment are all provided with connection portions, for example, the first step surface 21 is provided with a first connection portion 211, the second step surface 22 is provided with a second connection portion 221, the third step surface 23 is provided with a third connection portion 231, and the components such as a pcb board and a base can be fixed with the support through the connection piece matched with the connection portions.

In actual implementation, the connection between the step surface of the support and other components may be realized by other connection methods, and the embodiment is not particularly limited as long as the same fixing function can be realized. In addition, can also use different kinds of connecting portion and connecting piece to different step faces, for example first step face and third step face offer the screw, through screw connection PCB board and base, the second step face then carries out the connection of support and display module assembly backplate through the buckle.
The first connecting portion 211, the second connecting portion 221 and the third connecting portion 231 on the bracket shown in fig. 1 are all screw holes, the connecting pieces corresponding to the connecting portions are all back-locking screws, for different step surfaces, the number and positions of the screw holes formed on the surface of the connecting portions can be set according to the number and positions of the screw holes formed on the PCB board, the back plate of the display module or the base, and screw holes with different sizes are set for different components to fix the connecting portions by using screws with different sizes. The positions and the number of the screw holes shown in fig. 1 are only one kind of illustration, and are set according to actual requirements in actual setting. In addition, when carrying out the size design of support, can carry out the adjustment of the width of step face according to the position and the quantity of screw, under the circumstances of guaranteeing stable connection, make the edge of step face keep still a certain safe distance apart from the screw position, prevent to lead to the damage at the screw fastening after the support atress.
It should be noted that the first step surface 21 of the bracket realizes the fixation of the PCB board, the third step surface 23 realizes the fixation of the external base, and the second step surface 22 of the bracket is used for fixing the rear cover of the display module except for the fixation between the bracket body and the back plate of the display module, and the rear cover is used for covering the PCB board which is already fixed, so as to avoid the damage of elements on the circuit board caused by the exposure of the rear cover, and meanwhile, the back plate side of the display module can be more complete and unified. Similarly, the rear cover may be fixed to the second step surface 22 of the bracket by a screw or a buckle, and the embodiment is not limited to a specific connection and fixation method.

Meanwhile, when the rear cover contacts with the second step surface 22, the height difference between the third step surface 23 and the second step surface 22 should be greater than or equal to the thickness of the rear cover, and in general, it is only necessary to ensure that the surface of the rear cover, which is far from the second step surface 22 after being mounted, and the third step surface 23 are in the same horizontal plane.

In the actual manufacturing of the stent, the stent can be manufactured by a metal material or a hard plastic, and the stent can be manufactured into a solid structure or a hollow structure according to different manufacturing materials. Specifically, if plastic or metal with lighter weight or stronger ductility (such as aluminum) is used for manufacturing the bracket, the bracket can be manufactured into a solid structure, so that good supporting performance is ensured, and meanwhile, good strength can be ensured after the PCB and the base are connected; when stainless steel or metal with good supporting performance is used for manufacturing the bracket, a plate with a certain thickness can be adopted, the plate is bent to form a bracket pattern, and then screw holes or positioning grooves are manufactured.
