[0024] like Figures 1-4 ;

[0025] An electronic rearview mirror bracket structure for an automotive door panel includes a middle trim panel 1, an electronic rearview mirror cover 2, a lower body 5, and an electronic rearview mirror 6. A spring nut 3 is installed on the electronic rearview mirror bracket 2. The electronic rearview mirror cover 2 is pre-installed on the middle trim panel 1 via a gantry clip. The middle trim panel 1 assembly is pre-installed on the lower body 5. The middle trim panel 1, the electronic rearview mirror cover 2, and the lower body 5 are fastened together by Phillips head screws 4 and riveted together by welding posts. The electronic rearview mirror 6 is fastened to the electronic rearview mirror bracket 2 by bolts 7 and spring nuts 3.

[0026] The electronic rearview mirror area on car door panels has many parts and a complex structure. Therefore, the electronic rearview mirror bracket adopts a simplified structural design. To increase structural strength, the bracket features multiple recesses, protrusions, and ribs. It employs various fixing methods, including gantry clips, screw fastening, and BOSS pillar welding. The gantry clips are used for pre-installation; screws are used in specific locations for tightening, providing strong force and good results; and BOSS pillar welding is suitable for large-scale use due to its strong connection and low cost. To ensure a secure assembly between the electronic rearview mirror bracket and the center trim panel and lower body, the screw and welding points are relatively dense. Considering both strength and cost, the component wall thickness is designed to be 2.5mm. The appearance of the leather texture at position 8 and the piano lacquer at position 9 needs to be ergonomically verified to ensure that it does not affect the viewer's field of vision. At the same time, it is also necessary to ensure that the parts are not damaged after being demolded after the leather texture is corroded. Considering factors such as appearance, screen safety, and protective film treatment, the screen of the electronic rearview mirror 6 and the electronic rearview mirror bracket need to maintain a gap of at least 0.5mm. During assembly, the electronic rearview mirror 6 will also cooperate with the center trim panel 1. Since the center trim panel 1 is a covering part, the center trim panel 1 and the electronic rearview mirror 6 maintain a zero gap, making the installation and removal of the electronic rearview mirror 6 very convenient. It can be installed from the back of the door trim panel 1 and the bolts are tightened to complete the assembly. Disassembly is also completed by simply unscrewing the bolts, which is very convenient for later inspection and maintenance.

[0027] The electronic rearview mirror bracket is made of PC+ABS material, mainly based on the following factors: The electronic rearview mirror 6 is heavy and experiences significant vibration during driving. PC and ABS, as bracket materials, possess high strength and good toughness, allowing for minimal deformation of the electronic rearview mirror bracket under complex operating conditions, thus preventing damage to the screen of the electronic rearview mirror 6. The front door trim panel 1 is made of ABS material. The electronic rearview mirror bracket and trim panel 1 are connected using numerous welded posts. The use of PC+ABS material for the electronic rearview mirror bracket ensures more stable welding between the two parts, guaranteeing stability after assembly. The electronic rearview mirror 6 generates a large amount of heat during operation, so the selection of materials for the electronic rearview mirror bracket also needs to consider performance under high-temperature conditions.

[0028] After the electronic rearview mirror 6 is lit, the light from the screen will be reflected onto the electronic rearview mirror bracket. The bracket is made of PC+ABS material. After the parts are injection molded, the gloss is high. The light will be obviously reflected when it is projected onto the bracket, which will affect the driver's vision. Therefore, the textured area 8 of the bracket area needs to be treated with matte or textured finish to reduce light reflection, increase the texture and paint, and increase the scratch resistance of the parts.

[0029] In order to ensure a tight fit with surrounding components and maximize strength, the electronic rearview mirror cover plate 2 is provided with screw mounting holes 11, electronic rearview mirror bolt mounting holes 12, pre-installed buckle holes 13, main positioning holes 14 and welding column holes 15 in multiple locations.

[0030] like Figure 3 As shown, the screw mounting holes 11 include a1, a2, a3, a4, and a5. A screw mounting method is used to secure the electronic rearview mirror cover 2 to the center trim panel 1 and the lower body 5. This method is effective in situations where space is limited, welding is inconvenient, and the contour needs to be maintained. Figure 3 As shown, the electronic rearview mirror bolt mounting holes 12 include b1, b2, b3, and b4, which are bolt holes on the electronic rearview mirror cover plate 2 used to fix the electronic rearview mirror 6; as Figure 3 As shown, the pre-installed snap-fit ​​holes 13 include c1, c2, and c3, which are gantry snap-fit ​​holes that allow for the pre-installation of the electronic rearview mirror cover 2. This facilitates subsequent automated assembly line installation, similar to riveting and screw fastening. Additionally, secondary positioning is added to the side of the square holes. Figure 3 As shown, the main positioning hole 14 includes d, which is the main positioning hole for the electronic rearview mirror cover 2, used to ensure the positional accuracy of the parts and surrounding components during assembly, and to control the clearance and surface difference of the fit; as shown Figure 3 As shown, the welding post holes 15 include f1, f2, f3, f4, f5, and f6, which are welding post holes of the electronic rearview mirror cover plate 2. The welding posts on the lower body 5 and the middle trim plate 1 are inserted into the welding post holes 15 of the electronic rearview mirror cover plate 2, and are subsequently welded by the automated main line.

[0031] The electronic rearview mirror cover 2 has a leather texture 8 and a piano lacquer 9 on its surface. The leather texture 8 is treated with a fine etched leather texture, and the piano lacquer 9 is made by spraying piano lacquer. A masking groove 10 with a width of 0.5mm and a depth of 0.5mm is provided at the transition between the leather texture 8 and the piano lacquer 9 in order to cover the leather texture 8 during subsequent painting.

[0032] The working principle of this utility model is as follows: The cooperating parts include a center trim panel 1, an electronic rearview mirror cover 2, a lower body 5, and an electronic rearview mirror 6. The assembly sequence is as follows: spring nuts 3 are manually installed on the electronic rearview mirror cover 2; then, the electronic rearview mirror cover 2 is pre-installed onto the center trim panel 1 using a gantry clip; the center trim panel 1 assembly is pre-installed onto the lower body 5; then, it is secured and riveted using cross-head screws 4 on an automated main line; finally, bolts 7 and spring nuts 3 are used to secure the electronic rearview mirror 6 to the electronic rearview mirror cover 2. The electronic rearview mirror bracket structure is compact. To meet strength requirements, many steps and ribs are added for reinforcement. To ensure a tight fit with surrounding components and maximize strength, a screw-locking method is used. The electronic rearview mirror cover 2 is screwed onto the center trim panel 1 and the lower body 5 in locations with narrow spaces where welding is inconvenient and where maintaining the contour is crucial. It achieves a good effect. The bolt locking hole 12 of the electronic rearview mirror is a bolt hole on the electronic rearview mirror cover plate 2, which is used to fix the electronic rearview mirror 6. The pre-installation buckle hole 13 is a gantry buckle hole, which can realize the pre-installation of the electronic rearview mirror cover plate 2, which is convenient for the later automated main line to rivet welding and screw fastening. At the same time, the side of the square hole also adds a secondary positioning. The main positioning hole 14 is the main positioning of the electronic rearview mirror cover plate 2, which is used to ensure the position accuracy of the parts and the surrounding parts and control the gap surface difference of the fit. The welding column hole 15 is the welding column hole of the electronic rearview mirror cover plate 2. The welding columns on the lower body 5 and the middle trim plate 1 are inserted into the welding column hole 15 of the electronic rearview mirror cover plate 2, and then welded by the automated main line. The outer surface of the electronic rearview mirror cover plate 2 is provided with leather texture 8 and piano lacquer 9. The transition position of leather texture 8 and piano lacquer 9 is provided with a spray masking groove 10 to cover the leather texture 8 surface during subsequent painting.
