[0024] The first fixing sheet 10 includes a plate-shaped first sheet 11, welding legs 12 formed by bending and extending downward from both sides of the first sheet 11, and a rivet groove 14 opened at the front end of the first sheet 11. The welding legs 12 include a first welding leg 121 located at one side of the lateral direction and a second welding leg 122 located at the other side of the lateral direction. The first welding leg 121 and the second welding leg 122 are offset in the front-to-back direction, that is, the first welding leg 121 is close to the rear end of the first sheet 11, and the second welding leg 122 is close to the front end of the first sheet 11. The layout of the first welding leg 121 and the second welding leg 122 allows the first sheet to maintain sufficient holding force in both the front-to-back directions.
[0025] The first sheet 11 is provided with a bayonet 13 at the front side of the first welding leg 121, and the bayonet 13 is used for avoiding or locking. The rivet groove 14 extends from the back to the front, and includes an extension position 141 and a rivet position 142 formed at the front side of the extension position 141. The lateral width of the extension position 141 is smaller than the lateral width of the rivet position 142. The rivet position 142 is widened in the lateral direction, and the lateral ends are arc-shaped edge structures.
[0026] The second fixing plate 20 includes a second plate 21 attached to the upper side of the first plate 11, a limit plate 22 and a hook 23 formed by bending upward and extending from the periphery of the second plate 21, and a riveting plate 24 extending from the front end of the second plate 21. The front-to-back length of the first plate 11 is greater than the front-to-back length of the second plate 21. Specifically, the riveting groove 14 is located in front of the second plate 21 and corresponds to the riveting plate 24 in the vertical direction.
[0027] The limiting piece 22 includes a first limiting piece 221 and a second limiting piece 222 respectively bent upwardly and extended from the two lateral sides of the second sheet 21. The hook 23 includes a vertical portion 231 bent upwardly and extended from the front end of the second sheet 21 and a bent hook portion 232 bent backwardly from the top of the vertical portion 231. The hook 23 includes at least one pair, which are respectively located at the two lateral sides of the riveting sheet 24.
[0028] The riveting sheet 24 includes an inclined extension portion 241 formed by bending and extending obliquely forward and downward from the front end of the second sheet 21, and a riveting portion 242 formed by bending and extending parallel to the free end of the inclined extension portion 241. The transverse width of the inclined extension portion 241 is not greater than the transverse width of the extension position 141, and the riveting portion 242 matches the riveting position 142, and the riveting portion 242 is riveted into the riveting position 142, so that the upper and lower surfaces of the riveting position 242 are flush with the upper and lower surfaces of the first sheet 11. The inclined extension portion 241 is partially accommodated in the extension position 141, and partially exposed above the extension position 141.

[0030] The first fixing plate 10, the second fixing plate 20 and the connecting portion 30 are stamped from the same metal plate. Specifically, the structures of the first fixing plate 10 and the second fixing plate 20 are stamped on a flat metal plate, and then the flat metal plate is bent and flattened, that is, the first fixing plate 10 or the second fixing plate 20 is fixed, and then the second fixing plate 20 or the first fixing plate is bent in the opposite direction according to the bending area. At the same time, during the bending process, the riveted portion 242 of the second fixing plate 20 is riveted into the riveted position 142 of the first fixing plate 10, and the size edge of the riveted portion 242 can be slightly larger than the internal size of the riveted position 142 so that the two are riveted to produce greater interference and are fixed.
[0031] The opposing surfaces of the first fixing plate 10 and the second fixing plate 20 are attached to each other, the rear ends are connected and fixed together by the connecting portion 30 , and the front ends are connected and fixed together with the rivet plate 24 by the rivet groove 14 .
[0032] After the first fixing plate 10 and the second fixing plate 20 of the lens fixing bracket of the present application are bent and fitted together, they are riveted together with the rivet groove 14 and the rivet plate 24 at the front end, so that the first fixing plate 10 and the second fixing plate 20 are locked together at both the front and rear ends of the lens fixing bracket to prevent the front end from warping due to force after the lens module is installed.
