Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0042] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, “bound to”, “over”, or “covering” another element, it may be directly “on”, “connected to”, “bound to”, “over”, or “covering” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on”, “directly connected to”, “directly bound to”, “directly over”, or “directly covering” another element, there may be no other elements present between them.

[0043] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0044] Although terms such as "first," "second," and "third" may be used herein to describe various components, assemblies, regions, layers, or portions, these components, assemblies, regions, layers, or portions are not limited by these terms. Rather, these terms are only used to distinguish one component, component, region, layer, or portion from another component, component, region, layer, or portion. Therefore, without departing from the teachings of the examples described herein, a first component, component, region, layer, or portion referred to may also be referred to as a second component, component, region, layer, or portion.

[0056] In this embodiment, the screen assembly 1 includes a screen 9 and a first positioning column 10 that can serve as a first positioning portion.

[0057] Specifically, the first positioning column 10 is disposed on the backlight side of the screen 9 ; the backlight here refers to the side of the screen 9 that is not exposed.

[0058] Furthermore, the first positioning column 10 extends along the thickness direction of the screen 9 ; preferably, the height of the first positioning column 10 is equal to the total height of the PCB assembly 2 and the first shell assembly 3 .

[0059] Furthermore, two first positioning posts 10 are provided; the two first positioning posts 10 are arranged at intervals along the length direction of the screen 9 .

[0060] In this embodiment, the PCB assembly includes a PCB board.

[0061] Specifically, a first positioning hole is opened on the PCB board at a position corresponding to the first positioning column 10 , and the first positioning column 10 can pass through the first positioning hole to position the PCB board on the screen 9 .

[0062] In this embodiment, the first shell component 3 includes a first shell 14 .

[0063] Specifically, a second positioning hole 15 is opened on the first shell 14 at a position corresponding to the first positioning column 10 , and the first positioning column 10 passing through the PCB board can be inserted into the second positioning hole 15 to position the first shell 14 on the PCB board.

[0064] Preferably, the first positioning column 10 is interference-fitted with the first positioning hole and the second positioning hole 15 respectively.

[0065] In summary, the first PCB shell 14 can be positioned on the screen 9 through the first positioning column 10 .

[0066] In this embodiment, the first shell component 3 includes a second positioning column 13 of the second positioning portion; the second positioning column 13 is arranged on a side of the PCB board away from the screen 9 .

[0067] In this embodiment, the first shell component 3 further includes a heat sink 16 .

[0068] Specifically, the heat sink 16 is disposed on a side of the first shell 14 away from the PCB board. The heat sink 16 can effectively improve the heat transfer of the automobile instrument structure and increase the service life of the automobile instrument structure to a certain extent.

[0069] Furthermore, a plurality of heat sinks 16 are provided, the heat sinks 16 extend along the width direction of the first shell 14 , and the plurality of heat sinks 16 are arranged at intervals along the length direction of the first shell 14 .

[0070] In this embodiment, the first housing component 3 further includes a snap spring 17 .

[0071] Specifically, the retaining spring 17 is disposed on a side of the first shell 14 away from the PCB board; the retaining spring 17 can fix the automobile instrument structure to the vehicle body.

[0072] In summary, the automobile instrument structure is fixed to the vehicle body by means of the retaining spring 17, which can achieve simple disassembly and relatively firmer installation.

[0073] In this embodiment, the second shell assembly 4 includes a second shell 18 .

[0074] Specifically, the second shell 18 is in a frame structure and is surrounded by a receiving space 19 , and the screen assembly 1 , the PCB assembly 2 and the first shell assembly 3 are arranged in the receiving space 19 .

[0075] Furthermore, a long sponge with single-sided adhesive is attached to the edge of the second shell 18 facing the screen 9. In actual use, the screen 9 is directly pressed onto the second shell 18, eliminating the use of existing structural adhesive, thereby solving the problem of debonding caused by the use of structural adhesive. On the other hand, the long sponge can achieve a waterproof effect.

[0076] More specifically, the second shell assembly 4 further includes a connecting portion 20 ; the connecting portion 20 is disposed at both ends of the second shell 18 along the length direction, and the connecting portion 20 can fix the automobile instrument structure to the vehicle body.

[0077] Preferably, the connecting portion 20 is a connecting plate, which is disposed at both ends of the second shell 18 along the length direction. In actual use, screws can be used to pass through the connecting plate and the vehicle body in sequence to fix the vehicle instrument structure to the vehicle body.

[0078] In summary, the present application adopts a connection method of a retaining spring 17 in conjunction with a screw, which can enable the automobile instrument structure to be stably fixed to the vehicle body and is easy to disassemble.

[0079] In this embodiment, the first positioning member and the second fixing member are both screws. The number and position of the first positioning member and the second positioning member are not specifically limited and can be set according to actual conditions while satisfying the conditions of counterweight and avoidance.

[0080] Specifically, screw columns 21 are arranged at corresponding positions on the screen assembly 1, the PCB assembly 2, and the first shell assembly 3. The first positioning member (screw) is directly driven into the screw column 21 during the positioning process of the screen assembly 1, the PCB assembly 2, and the first shell assembly 3, so as to avoid uneven force as much as possible and effectively reduce the Mura phenomenon.
