[0026] The mounting base 10 includes a base plate 11, a first side plate 12, a second side plate 13, a first mounting plate 14, and a second mounting plate 15. The first side plate 12 and the second side plate 13 are spaced apart on the surface of the base plate 11, forming a first mounting groove 110 between the base plate 11, the first side plate 12, and the second side plate 13. The first mounting plate 14 and the second mounting plate 15 are fixed to the surface of the second side plate 13 facing away from the first side plate 12, forming a second mounting groove 120 between the first side plate 12, the first mounting plate 14, and the second mounting plate 15.

[0027] In some embodiments, the base plate 11, the first side plate 12, and the second side plate 13 are integrally formed.

[0030] The first mounting plate 14 has a first mounting hole 140, and the second mounting plate 15 has a second mounting hole 150. The lens barrel 3 includes two mounting portions 302 spaced apart, which are respectively mounted on the first mounting plate 14 and the second mounting plate 15. In use, the mounting portions 302 of the lens barrel 3 are accommodated in the second mounting groove 120, and then two fasteners (not shown) are passed through the first mounting hole 140 and the second mounting hole 150 respectively and connected to the two mounting portions 302 to fix the lens barrel 3 onto the auxiliary assembly fixture 1. The dimensions of the first mounting hole 140 and the second mounting hole 150 are respectively adapted to the dimensions of the corresponding fasteners, so that the fasteners can be relatively fixedly connected to the corresponding first mounting plate 14 or second mounting plate 15 after being inserted into the corresponding first mounting hole 140 or second mounting hole 150. The number of first mounting holes 140 can be one, two or more, and this application does not limit it. The number of second mounting holes 150 is the same as the number of first mounting holes 140.

[0031] The mounting base 10 includes a reinforcing plate 16, which is fixed to the side of the base plate 11 away from the first mounting groove 110 to increase the strength of the first mounting groove 110.

[0032] Mounting base 10 includes a second connecting plate 17 and a first connecting plate 18, which are connected to the same side of reinforcing plate 16 and spaced apart. Positioning block 20 is connected to the first connecting plate 18. First mounting plate 14 is fixedly supported on the second connecting plate 17, and second mounting plate 15 is fixedly supported on the first connecting plate 18. Positioning block 20 and second mounting plate 15 are spaced apart, allowing the lens barrel 3 to be positioned between the first connecting plate 18 and the positioning block 20.

[0033] The reinforcing plate 16, the second connecting plate 17, and the first connecting plate 18 are arranged on the same plane. In some embodiments, the reinforcing plate 16, the second connecting plate 17, and the first connecting plate 18 are integrally formed.

[0034] The first connecting plate 18 includes a first surface 181, a second surface 182, a first side surface 183, a second side surface 184, and a third side surface 185. The first surface 181 and the second surface 182 are arranged opposite to and parallel to each other, and the second mounting plate 15 is fixed to the first surface 181. The first side surface 183 and the second side surface 184 are arranged opposite to and parallel to each other, and each side surface 183 and the second side surface 184 are independently connected to the first surface 181 and the second surface 182. In the direction from the first mounting plate 14 to the second mounting plate 15, the first side surface 183 is closer to the first mounting plate 14 than the second side surface 184. The third side surface 185 connects the first surface 181, the second surface 182, and the first side surface 183. The third side surface 185 forms a 45° angle with the first side surface 183.

[0035] The positioning block 20 is fitted to the third side surface 185. Specifically, the positioning block 20 includes a connecting part 21 and a positioning part 22 arranged perpendicularly to each other. The connecting part 21 is fixedly disposed on the second surface 182. The positioning part 22 is connected to the connecting part 21 and fitted to the third side surface 185, so that the positioning part 22 can cooperate with the mirror barrel 3 to install the reflector 2 at a 45° angle. A first screw hole 210 is provided in the positioning part 22. The first side plate 12 and the second side plate 13 are perpendicular to the first connecting plate 18. When light incident on the reflector 2 at a 45° angle is reflected to the reflector 4 and returns along its original path, it can be determined that the installation position of the reflector 2 on the mirror barrel 3 is accurate.

[0036] In some embodiments, the mounting base 10 and the positioning block 20 are made of stainless steel.

[0037] The size of the first mounting groove 110 is slightly larger than the size of the reflector 4, so that the reflector 4 can be inserted into the first mounting groove 110 and the position of the reflector 4 can be finely adjusted within the first mounting groove 110.

[0038] The auxiliary assembly fixture 1 includes a second adjusting member 40. The mounting base 10 is provided with a second screw hole 121 communicating with the first mounting groove 110. Specifically, the second screw hole 121 is provided in the first side plate 12. The second adjusting member 40 is configured to be screwed into the second screw hole 121 and used to press against the reflector 4 to fine-tune the position of the reflector 4.

[0039] The first adjusting member 30 includes a first screw 31 and a first nut 32. The first screw 31 is screwed into a first screw hole 210. The first nut 32 is connected to one end of the first screw 31, and the diameter of the first nut 32 is larger than the diameter of the first screw 31. The first screw 31 and the first nut 32 may be made of metal.

[0040] The first adjusting member 30 also includes a first buffer pad 33. The first buffer pad 33 is disposed at the end of the first screw 31 opposite to the first nut 32. The diameter of the first buffer pad 33 is smaller than the diameter of the first screw 31. The first adjusting member 30 abuts against the reflector 2 through the first buffer pad 33, which can reduce the risk of the first adjusting member 30 damaging or scratching the reflector 2 when pressing against and fixing the reflector 2. The first buffer pad 33 may be made of rubber.

[0041] The second adjusting member 40 includes a second screw 41 and a second nut 42. The second screw 41 is screwed into the second screw hole 121. The second nut 42 is connected to one end of the second screw 41, and the diameter of the second nut 42 is larger than the diameter of the second screw 41. The second screw 41 and the second nut 42 may be made of metal.

[0042] The second adjusting member 40 also includes a second buffer pad 43. The second buffer pad 43 is disposed at the end of the second screw 41 opposite to the second nut 42. The diameter of the second buffer pad 43 is smaller than the diameter of the second screw 41. The second adjusting member 40 abuts against the reflector 4 through the second buffer pad 43, which can reduce the risk of the second adjusting member 40 damaging or scratching the reflector 4 when pushing and fixing it. The second buffer pad 43 may be made of rubber.

[0043] In use, first insert the reflector 4 into the first mounting groove 110, insert the second adjusting member 40 into the second screw hole 121, and tighten the second adjusting member 40 so that the second adjusting member 40 pushes the reflector 4 against the second side plate 13; then fix the mounting part 302 of the mirror barrel 3 into the second mounting groove 120, wherein the mirror barrel 3 abuts against the surface of the first mounting plate 14 and the second mounting plate 15 away from the second side plate 13; then place the reflector 2 between the positioning block 20 and the mirror barrel 3, insert the first adjusting member 30 into the first screw hole 210, and tighten the first adjusting member 30 so that the first adjusting member 30 pushes the reflector 2 into the mounting hole 301 of the mirror barrel 3 to achieve the pre-fixation of the reflector 2; finally, inject glue into the edge gap of the reflector 2 to complete the installation and fixation of the reflector 2.

[0044] The auxiliary assembly fixture 1 provided in this application is provided with a first mounting groove 110 for accommodating and fixing the reflector 4 and a partial second mounting groove 120 for accommodating the mirror barrel 3, and a first adjusting member 30 for pressing against the reflector 2, so that the reflector 2, the mirror barrel 3 and the reflector 4 can be stably fixed on the auxiliary assembly fixture 1. Compared with the method of fixing the reflector and the lighting module with rubber bands, the auxiliary assembly fixture 1 of this application fixes the reflector 2 and the mirror barrel 3. When the mirror barrel 3 is touched, the auxiliary assembly fixture 1 will not deform and thus the reflector 3 will not be displaced, improving the assembly accuracy of the reflector 3.

[0045] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with this application are still within the scope of this application.
