DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a license plate recognition device comprises a chassis 1, a recognition device 14 and an interception plate 2 connected to the rear side of the chassis 1, the chassis 1 can drive the interception plate 2 to rotate up and down, the chassis 1 is rotatably connected with an upper rotating ring 4 and a lower rotating ring 5 distributed up and down, two lead screws 15 are mirror-imaged between the upper rotating ring 4 and the lower rotating ring 5 with the center of the chassis 1 as the center, the two lead screws 15 are rotatably connected to the opposite sides of the upper rotating ring 4 and the lower rotating ring 5, the two lead screws 15 are threadedly connected with a lifting plate 3, the upper side of the lifting plate 3 is symmetrically fixed with two electric telescopic rods 11 by bolts with the lead screw 15 as the center, the output shafts of the two electric telescopic rods 11 are away from the chassis 1 and connected with a mounting plate 12, the upper side of the mounting plate 12 is provided with an recognition device 14, and the above-mentioned rotation connection methods are all bearings or other common rotation connection methods;

[0022] The lower rotating ring 5 is provided with a driving assembly for driving the lead screw 15 to rotate;

[0023] The chassis 1 is provided with a rotating assembly for driving the lifting plate 3 to rotate.

[0024] When the car is difficult to adjust its position and is not recognized by the recognition device 14, the staff can adjust the height and recognition direction of the recognition device 14 through the driving component and the rotating component. After the height and recognition direction are adjusted, the staff can control the output shaft of the electric telescopic rod 11 to extend and retract, thereby controlling the horizontal position of the recognition device 14, so that the recognition device 14 can recognize the license plate of the car, thereby improving the recognition efficiency of the recognition device 14 and avoiding the situation where the car cannot be recognized due to inconvenience in moving. After the recognition is completed, the staff can control the output shaft, driving component and rotating component of the electric telescopic rod 11 to move the recognition device 14 to the initial position to prevent the car from colliding with the recognition device 14 and causing damage.

[0025] In this embodiment, the driving assembly includes a screw motor 10 fixed to the lower side of the lower rotating ring 5 by bolts and a synchronous gear ring 18 rotatably connected to the upper side of the upper rotating ring 4 through a middle bearing. The upper end of the screw 15 passes through the upper rotating ring 4 and is connected to a synchronous gear 19, which meshes with the synchronous gear ring 18. The output shaft of the screw motor 10 passes through the lower rotating ring 5 and is connected to one of the screws 15. When in use, the output end of the screw motor 10 drives the screw 15 to rotate, and the synchronous gear 19 at the upper end of the screw 15 drives the synchronous gear ring 18 to rotate. The synchronous gear ring 18 drives the other screw 15 to rotate through the synchronous gear 19 on the other screw 15, so that the two screws 15 rotate synchronously, thereby realizing the up and down movement of the lifting plate 3 on the two screws 15, which is convenient for the staff to adjust the height of the identification device 14 and improve the identification efficiency of the identification device 14.

[0026] In this embodiment, the rotating assembly includes a gear ring 7 integrally formed on the lower side of the lower rotating ring 5, a gear 9 meshing with the gear ring 7, a support plate 8 arranged below the gear ring 7, and a rotating motor 6 fixed to the upper side of the support plate 8 by bolts. The output shaft of the rotating motor 6 is connected to the gear 9, and the support plate 8 is welded to the annular side of the chassis 1. When in use, the output shaft of the rotating motor 6 can drive the gear 9 to rotate, and then the upper rotating ring 4 and the lower rotating ring 5 are rotated through the meshing of the gear 9 and the gear ring 7, thereby adjusting the recognition angle of the recognition device 14, improving the recognition range of the recognition device 14, and improving the recognition efficiency.

[0027] In this embodiment, the upper side of the mounting plate 12 is rotatably connected to a mounting seat 13, and an identification device 14 is installed on the upper side of the mounting seat 13 by bolts. After the height, horizontal position and identification angle of the identification device 14 are adjusted, the identification device 14 still cannot identify the license plate. The staff can rotate the identification device 14 on the mounting seat 13 to further adjust the identification direction of the identification device 14 so that the identification device 14 can identify the car license plate, thereby ensuring the recognition effect of the identification device 14.

[0028] In this embodiment, a fill light 17 is installed on the left side of the mounting base 13 by bolts. The fill light 17 can move with the mounting base 13, so that the illumination direction of the fill light 17 is always the same as the recognition range of the recognition device 14. When used at night, the fill light 17 can fill in the recognition device 14 to improve the recognition effect of the recognition device 14.

[0029] In this embodiment, a mark 16 is glued to the annular side of the chassis 1. When in use, the mark 16 is located at the initial position of the identification device 14, so that the staff can adjust the identification device 14 back to the initial position after the identification device 14 completes the identification, thereby reducing the staff's adjustment time.
