Detailed implementation manners

[0029] The core of the present invention lies in disclosing an automotive electronic exterior mirror display stand to perform in - vehicle state testing and effect display on the automotive electronic exterior mirror and improve the aesthetics during the testing process on the stand.

[0030] To enable those skilled in the art to better understand the solution of the present utility model, the embodiments of the present utility model will be described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the content of the utility model recorded in the claims in any way. Additionally, all the content of the configurations shown in the following embodiments is not limited to what is necessary for the solution of the utility model recorded in the claims.

[0031] As Figure 1-7 shown, the automotive electronic outside rearview mirror display stand provided by the embodiment of the present utility model includes a base 10 and a support frame 20, and the base 10 and the support frame 20 are assembled and connected into an integral structure. Here, the assembly connection means that the base 10 and the support frame 20 can be connected by bonding, snap connection, bolt connection or other connection methods. Among them, the support frame 20 is used to carry the camera module 30 for image acquisition. The support frame 20 is specifically an extended structure based on its contact surface with the base 10, and a housing is sleeved on one side of the extended area to form a cavity structure. The camera module 30 is installed and protected within the enclosed area of the housing and the support frame 20. At the same time, a through hole 210 is provided on the support frame 20, and the position of the through hole 210 is set relative to the camera module 30, so that the camera module 30 can acquire images through the through hole 210. On the one hand, the above structure is closer to the form of the camera module 30 when it is actually used in a vehicle, that is, the camera module 30 is protected by the housing structure and acquires images through the hole structure. On the other hand, the setting of the through hole 210 can play a certain image filtering effect, and when the electronic outside rearview mirror is exhibited, it will not cause the problem that the acquired images are too messy and affect the display effect due to the large number of other devices and personnel.

[0032] The base 10 is a cavity structure for installing the display screen 40 and the circuit board 50 inside. The circuit board 50 is a PCBA control board, that is, a printed circuit board on which electronic components have been soldered and assembled. It is electrically connected to the camera module 30 to receive and process the image information acquired by the camera module 30. At the same time, the circuit board 50 is electrically connected to the display screen 40 to display the processed image results on the display screen 40. The base 10 specifically includes a front panel 110 and a rear cover 120 to block the openings in the front and rear directions of the base 10. At the same time, a display opening 1110 is specifically provided on the front panel 110. The display screen 40 is installed inside the base 10 and is wrapped and protected by the front panel 110, and the content of the display screen 40 is exposed through the opening area of the display opening 1110. Designing the size of the display opening 1110 can simulate the display range and viewing state of the display screen 40 in the actual vehicle state, which is more conducive to the complete display of the product.

[0033] The rear cover plate 120 is used to support and fix the circuit board 50. At the same time, several wire harness windows are provided on the base 10. The electrical signal connecting wire harnesses between the camera module 30, the display screen 40 and the circuit board 50, as well as their respective power supply wire harnesses, pass through the wire harness windows when passing through the base 10 and are not all exposed. When the electronic outside rearview mirror product is displayed on the gantry provided by the embodiment of the present utility model, the aesthetics of the product will not be affected due to the exposure of the wire harnesses, thereby improving the refined design level of the product.

[0034] The automotive electronic outside rearview mirror display gantry provided by the embodiment of the present utility model simulates the vehicle body and the rearview mirror state of a real vehicle through the base 10 and the support frame 20, so that the display states of the camera module 30, the display screen 40 and the circuit board 50 are closer to the real vehicle installation state and improve the display effect. Specifically, a through hole 210 is provided on the support frame 20 for installing and protecting the camera module 30 to control the image acquisition range of the camera module 30 while simulating the protection state of the camera module 30 in a real vehicle, and to avoid excessive peripheral image information during display from affecting the display effect on the display screen 40. The base 10 is provided with a display opening 1110 on the front panel 110, so that personnel can intuitively feel the display range of the display in the real vehicle state. At the same time, the circuit board 50 is fixed by the rear cover plate 120, and several wire harness windows are also provided on the base 10, so that the wire harnesses travel through the inside of the base 10 to reduce the number of exposed wire harnesses, thereby being able to display the aesthetics and refined design level of the electronic outside rearview mirror and improving the exhibition effect of the product.

[0035] In order to smoothly install the display screen 40 and the front panel 110 on the base 10, the display gantry provided by the embodiment of the present utility model is also provided with several fixed lugs 130 on the base 10. The fixed lugs 130 are preferably L-shaped plate structures. After the display screen 40 is limited and supported by the side plates of the several fixed lugs 130 during installation, the bolt holes on the display screen 40 and the fixed lugs 130 are aligned to connect the display screen 40 and the fixed lugs 130 through bolts. At the same time, it is preferably that at least one fixed lug 130 is provided in each of the four corner areas of the display screen 40 to effectively limit and support the display screen 40.

[0036] For the convenience of installing the front panel 110, a chute 150 is provided in the opening area of the base 10 for installing the front panel 110. The corresponding side edges of the front panel 110 are provided with thin-wall sliding structures to slidably cooperate with the chute 150.
