DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-10 The automobile exterior rearview mirror is mounted on the front outer side of the vehicle and is used to observe the road conditions behind the vehicle. It includes a mounting assembly 10 mounted on the vehicle body. The mounting assembly 10 is used to be mounted on the vehicle body and mainly provides a mounting position for the exterior rearview mirror. Specifically, the mounting assembly 10 includes a fixed arm fixed on the vehicle body and an arm shell 11 mounted outside the fixed arm for protecting the fixed arm. The mirror body assembly 12 mounted on the mounting assembly 10 is rotatable, that is, the mirror body assembly 12 can be rotated relative to the mounting assembly 10. The mirror body assembly 12 and the mounting assembly 10 are folded or unfolded by electric / manual operation. The electric / manual operation here can adopt the commonly used folding structure of the exterior rearview mirror. It is more necessary to choose whether to use electric folding or manual folding. The corresponding rotation structure between the mirror body assembly 12 and the mounting assembly 10 is not repeated.

[0033] Among them, the mirror body assembly 12 includes a mirror housing 13, a lens 14, a lens deflector 15, and a turn signal 16. The lens deflector 15 is in the mirror housing 13, and the lens 14 is located in front of the mirror housing 13. The lens 14 is connected to the lens deflector 15. The lens deflector 15 can drive the lens 14 to form a certain angle adjustment to change the observation position of the lens 14. The lens deflector 15 can adopt the currently commonly used electric or manual deflectors. The turn signal 16 is installed at the rear of the mirror housing 13. The turn signal 16 extends from the rear of the mirror body toward a side wall of the mirror housing 13. When the vehicle turns, the vehicle's turning information is sent to other traffic participants in front and on the side of the vehicle. The above structure can realize the basic function of the rearview mirror, that is, it can observe the traffic conditions on the rear road and give the vehicle turning prompts.

[0034] A first assembly hole 17 is opened downward at the bottom of the mirror housing 13, and a projection lamp assembly 18 is installed at the first assembly hole 17. The projection lamp assembly 18 is used to project a light pattern toward the bottom of the rearview mirror to enhance the light and beauty under the rearview mirror during the door opening and closing process; specifically, the projection lamp assembly 18 includes a base 19, a lower shell 20, an upper shell 21, a shell cover 22, a projection assembly 23, and a projection harness 24.

[0035] The first assembly hole 17 is located in the mirror housing 13 and has three stopper portions 25 and three supporting protrusions 26 formed on its outer periphery. The three stopper portions 25 are arranged at intervals, and gaps 27 are formed between adjacent stopper portions 25. The supporting protrusions 26 are located at the gaps 27. The stopper portion 25 is formed by the inward depression of the hole edge at the outer end of the first assembly hole 17. The three stopper portions 25 are arranged along the outer periphery of the first assembly hole 17, and the three supporting protrusions 26 are integrally formed on the inner wall of the mirror housing 13.

[0036] The base 19 has three sections of fitting parts 28 and three clamping parts 29 on its outer periphery. The fitting parts 28 fit with the lower surface of the stop part 25. The clamping parts 29 extend from the notch 27 into the interior of the mirror housing and cooperate with the supporting protrusion 26 to generate a locking force. The fitting parts 28 are stepped on the outer periphery of the lower end of the base 19, and the step surface fits with the lower surface of the stop part 25 to form a seal. The clamping parts 29 are buckles formed between the fitting parts 28. The buckles penetrate into the mirror housing 13 through the notch 27 and clamp the inner side of the supporting protrusion 26 to generate a clamping force, so that the base 19 is assembled in the first assembly hole 17 of the mirror housing 13 by a clamping method. When disassembling, the base 19 can be disassembled by separating the buckle from the supporting protrusion 26. And through the cooperation of multiple stop parts and fitting parts, and multiple clamping parts and supporting protrusions, the clamping stability between the base and the mirror housing is enhanced.

[0037] The lower shell 20 is assembled on the base 19, and a gap is reserved between the lower end of the lower shell 20 and the base 19. The upper shell 21 can be detachably assembled on the lower shell 20, such as by a snap-fit ​​method, so as to facilitate the assembly and disassembly between the upper shell 21 and the lower shell 20. An assembly space for assembling the projection assembly 23 is formed in the upper shell 21. The projection end 31 of the projection assembly 23 passes through the bottom of the upper shell 21 and is located below the lower shell 20. The shell cover 22 is assembled on the upper shell 21 to form a cover for the assembly space, so as to cover the projection assembly 23 in the assembly space to form a certain protection; the projection assembly 23 is an existing structure, and its details are not repeated here. Through the above, by assembling and disassembling between the base 19 and the mirror shell 13, the assembly and disassembly between the entire projection lamp assembly 18 and the mirror shell 13 can be realized. At the same time, it is also convenient to assemble and disassemble between the upper shell 21 and the lower shell 20, so as to facilitate the installation and maintenance of the projection assembly 23.

[0038] A threading hole 30 is provided at the lower end of the upper shell 21 for the projection wiring harness 24 to pass through the assembly space from the outside to form an electrical connection between the projection wiring harness 24 and the projection component 23. A sealing component is sleeved on the projection wiring harness 24 to form a seal with the inner wall of the threading hole 30. The sealing component adopts a bellows-shaped sealing ring to enhance the sealing performance.

[0039] The base 19 is provided with an enlarged projection hole 32 for projecting the light projected by the projection component 23 to the bottom of the mirror housing 13. The outer periphery of the projection end 31 of the projection component 23 is fitted with the outer periphery of the projection hole 32 on the inner side of the base 19, that is, the outer periphery of the projection end 31 forms a first fitting surface, and the outer periphery of the projection hole 32 on the inner side of the base 19 forms a second fitting surface. The first fitting surface is fitted with the second fitting surface, so that the sealing performance here can be enhanced. Of course, a sealing ring can also be added to further improve the sealing ability here.

[0040] In some implementations, at least two vertically arranged support columns 33 are fixedly disposed inside the base 19, and the support columns 33 are located at the inner periphery of the base 19. Connecting ears 34 that match the support columns 33 are fixedly disposed on the outer periphery of the lower shell 20. The connecting ears 34 extend from the outer wall of the lower shell 20 toward the outside. The support columns 33 and the connecting ears 34 are connected by plugging or screw connectors. The lower end of the lower shell 20 is open, so that the projection end 31 of the projection assembly 23 is exposed. The lower shell 20 is connected to the base 19 by connecting the support columns 33 and the connecting ears 34.

[0041] In some implementations, a plurality of support blocks 35 are arranged at intervals on the inner periphery of the base 19 on the inner side of the base 19, and the inner side surface of each support block 35 has a step surface 36. The step surfaces 36 on the plurality of support blocks 35 constitute a bearing surface for supporting the lower end surface of the lower shell 20, and the inner side surface of the support block 35 cooperates with the outer peripheral surface of the lower end of the lower shell 20. Through the cooperation of the support blocks 35, the lower end surface and the outer periphery of the lower shell 20 are constrained to ensure that the lower shell 20 is stably located in the base 19 after being assembled in place; through the arrangement of the support blocks 35, a gap can be retained between the lower end surface of the lower shell 20 and the bottom surface of the base 19, which helps to circulate and diffuse the heat at the projection end 31 of the projection assembly 23.

[0042] In some implementations, a notch 37 lower than the lower end surface of the lower housing 20 is provided on an outer wall at the lower end of the lower housing 20, and the projection harness 24 passes through the notch 37 from the outside of the projection lamp assembly 18 and penetrates into the assembly space; one side of the assembly space is an installation space 38 for the projection assembly 23, and the other side is a wiring space 39 for the projection harness 24 and the projection assembly 23. The installation space 38 and the wiring space 39 are arranged on the left and right to facilitate wiring, and at the same time, the projection harness 24 is introduced into the wiring space to form a certain protection.

[0043] In some implementations, a clearance hole 40 for the projection assembly 23 to pass through is provided at one side of the threading hole 30 at the bottom of the upper shell 21. The outer end of the clearance hole 40 extends toward the bottom of the upper shell 21 to form a lower annular extension 41, and the inner end of the clearance hole 40 extends toward the inside of the upper shell 21 to form an upper annular extension 42. When the projection assembly 23 passes through the clearance hole 40, the upper and lower annular extensions 41 contact the outer wall of the projection assembly 23, thereby increasing the fitting surface between the projection assembly 23 and the upper shell 21, thereby enhancing the stability of the projection assembly 23 installed in the clearance hole 40.

[0044] In some implementations, an insert block 43 is fixedly provided on the outer wall of the lower annular extension portion 41, and the projection end 31 of the projection assembly 23 is provided with a socket portion 44 docked with the insert block 43. The insert block 43 and the socket portion 44 can be inserted into the socket portion 44 in an interference fit manner, and the insert block 43 is inserted into the socket portion 44 to avoid rotation of the projection assembly 23, while also further enhancing the assembly stability between the projection assembly 23 and the upper shell 21.

[0045] In some implementations, two constraint columns 45 are fixedly provided at the bottom of the upper shell 21 on the outside of the upper annular extension portion 42. The constraint columns 45 are located in the middle position of the bottom of the upper shell 21, that is, between the installation space and the wiring space. The projection assembly 23 is constrained by the outer periphery of the constraint columns 45 contacting the outer periphery of the upper end of the projection assembly 23.

[0046] In some implementations, a second assembly hole 46 is opened downward at the bottom of the mirror housing 13, and a camera assembly 47 is installed in the second assembly hole 46. The camera assembly 47 is located outside the projection lamp assembly 18; the camera assembly 47 is located at the intersection of the lower side and the outer side of the mirror housing 13.
