Through three-dimensional vision and auxiliary sensor fusion technology, it collects and analyzes the features of the vehicle's face, rear, and body in real time, enabling refined detection of vehicles passing through toll lanes. However, existing vehicle recognition devices mostly use cameras in fixed positions that can only be adjusted vertically and cannot adjust the width of the image captured. As a result, they are difficult to accurately recognize vehicles with different widths when they stop. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, this utility model provides a vehicle recognition device that is easy to install and has the advantage of being able to adjust the camera horizontally to increase the recognition width.

[0009] As a preferred embodiment of this utility model, a brush is fixedly installed inside the slide groove. There are multiple brushes, all of which are located inside the base. The brushes are made of a relatively soft material.
[0010] As a preferred technical solution of this utility model, the inside of the box is provided with a display screen, the inside of the base is provided with a drain outlet, the drain outlet passes through the inside of the brush, there are multiple drain outlets, and all of the multiple drain outlets are cylindrical.
[0011] As a preferred embodiment of this utility model, there are two of each of the sliding groove, slider, and support rod. The two sliding grooves and the two sliders are located inside the base, and the two support rods are located at the front and rear ends of the mother plate, respectively.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model has a fixed plate fixedly installed at the rear of the housing, a motor fixedly installed at the bottom of the fixed plate, an output shaft fixedly installed at the output end of the motor, and a gear fixedly installed at the end of the output shaft away from the motor. The gear and the gear ring are meshed. When it is necessary to identify vehicle bodies of different widths, the motor is first started to drive the gear to rotate through the output shaft. At this time, since the gear and the gear ring are meshed and the gear ring is fixedly connected to the connecting shaft, the connecting shaft is rotatably connected to the top of the housing. The connecting shaft is also fixedly connected to the fixed rod, and a fixed block is sleeved on the outside of the fixed rod.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 5 As shown, this utility model provides a vehicle recognition device that is easy to install, including a base 1. The base 1 has a groove 2 inside, and a slider 3 is slidably connected inside the groove 2. A support rod 4 is fixedly installed above the slider 3. A housing 5 is fixedly installed above the support rod 4. A connecting shaft 6 is rotatably connected to the top of the housing 5. A fixing rod 7 is fixedly installed above the connecting shaft 6. A fixing block 8 is rotatably connected to the outside of the fixing rod 7. A camera 9 is fixedly installed above the fixing block 8. A toothed ring 10 is fixedly installed on the outside of the connecting shaft 6.
[0023] When dealing with vehicles of different heights, the box 5 is first moved to the designated position. Then, the connecting shaft 6 is rotated and connected to the box 5 to adjust the angle. Since the connecting shaft 6 is fixedly connected to the fixing rod 7 and the fixing rod 7 is rotatably connected to the fixing block 8, the vertical height of the camera 9 is adjusted when the fixing block 8 is rotated and connected to the fixing rod 7, so as to facilitate the recognition of vehicles of different heights.
[0024] Among them, a fixing plate 11 is fixedly installed at the rear of the housing 5, a motor 12 is fixedly installed at the bottom of the fixing plate 11, an output shaft 13 is fixedly installed at the output end of the motor 12, and a gear 14 is fixedly installed at the end of the output shaft 13 away from the motor 12. The gear 14 is meshed with the gear ring 10.
[0025] When it is necessary to identify vehicle bodies of different widths, the motor 12 is first started, which drives the gear 14 to rotate through the output shaft 13. At this time, since the gear 14 meshes with the gear ring 10 and the gear ring 10 is fixedly connected to the connecting shaft 6, the connecting shaft 6 is rotatably connected to the top of the housing 5. The connecting shaft 6 is also fixedly connected to the fixing rod 7, and a fixing block 8 is sleeved on the outside of the fixing rod 7. When the fixing rod 7 rotates, the fixing block 8 can drive the camera 9 to rotate in the lateral angle, thereby increasing the overall recognition width of the camera 9 and achieving the effect of increasing the lateral recognition of the camera 9.
[0026] Among them, a screw mother plate 15 is fixedly installed on the inner side of the support rod 4, a positioning plate 16 is fixedly installed on the top of the base 1, a second motor 17 is fixedly installed behind the positioning plate 16, a lead screw 18 is fixedly installed at the output end of the second motor 17, and the lead screw 18 meshes with the screw mother plate 15.
[0027] When multiple vehicles are queuing for recognition, there may be situations where the license plate of a vehicle following too closely is obscured by the vehicle in front, making it impossible to recognize. In such cases, the vehicle behind may need to reverse to enter, but it may be blocked by a third vehicle, causing a general traffic jam. At this point, the starter motor 17 drives the lead screw 18 to rotate, causing the lead screw 18 to engage with the lead screw plate 15. Since the lead screw plate 15 is fixedly connected to the support rod 4, during the engagement process, the support rod 4 will move and adjust its position through the sliding action of the slider 3 and the sliding groove 2, achieving the effect of recognition without reversing, improving vehicle recognition efficiency and preventing traffic jams.
[0028] A limiting plate 19 is fixedly installed on the top of the base 1. The limiting plate 19 is rotatably connected to the lead screw 18, and the limiting plate 19 is located in front of the support rod 4.
[0029] The main function of the limiting plate 19 is to limit the screw nut plate 15 to prevent the screw nut plate 15 from falling off due to poor control during the meshing process between the screw 18 and the screw nut plate 15.
[0030] The box 5 is equipped with multiple supplementary lights 20, which are located on the right side of the box 5.
[0031] The main function of the multiple supplementary lights 20 is to increase the light source in the vicinity when it is very dark at night, so that the camera 9 can more easily identify the vehicle, and at the same time provide supplementary lighting in front of the gate to ensure accurate parking position.
[0032] The slide 2 has multiple brushes 22 fixedly installed inside it, and all brushes 22 are located inside the base 1. The material of the brushes 22 is relatively soft.
[0033] The main function of multiple brushes 22 is to protect the inside of the slide 2, preventing the base 1 from being outdoors for a long time, which would cause a lot of debris to fall into the inside of the slide 2, thus blocking the sliding effect of the slider 3 and the slide 2, thereby affecting the effect of the support rod 4 in moving the box 5 back and forth.
[0034] The cabinet 5 has a display screen 21 inside, and the base 1 has a drain outlet 23 inside. The drain outlet 23 passes through the inside of the brush 22. There are multiple drain outlets 23, and all of them are cylindrical.
[0035] The main function of the multiple drain outlets 23 is to drain water from the inside of the base 1. When it rains, rainwater will enter the inside of the slide 2. At this time, the drain outlets 23 will promptly drain the water from the inside of the slide 2 to prevent rainwater from accumulating inside the slide 2 and causing corrosion.
[0036] There are two of each of the following: the two slide grooves 2, the two sliders 3, and the two support rods 4. The two slide grooves 2 and the two sliders 3 are located inside the base 1, and the two support rods 4 are located at the front and rear ends of the mother plate 15, respectively.
[0037] The two sliders 3 are slidably connected to the two slide grooves 2, thereby allowing the two support rods 4 to move back and forth. This ensures that the two support rods 4 have a certain stability when moving the box 5. At the same time, the sliding action between the two sliders 3 and the two slide grooves 2 facilitates the installation of the two support rods 4 and the box 5, achieving the effect of convenient installation of the whole device.
[0038] Working principle and usage process of this utility model:
[0039] Firstly, a sliding groove 2 is provided inside the base 1, and a slider 3 is slidably connected inside the sliding groove 2. A support rod 4 is fixedly installed above the slider 3, and a housing 5 is fixedly installed above the support rod 4. The slider 3 is slidably connected to the sliding groove 2, thereby allowing the support rod 4 to move back and forth, ensuring that the support rod 4 has a certain stability when moving the housing 5. At the same time, the sliding action between the slider 3 and the sliding groove 2 is used to install the support rod 4 and the housing 5, achieving the effect of convenient installation of the entire device.
[0040] A fixing plate 11 is fixedly installed at the rear of the housing 5. A motor 12 is fixedly installed at the bottom of the fixing plate 11. An output shaft 13 is fixedly installed at the output end of the motor 12. A gear 14 is fixedly installed at the end of the output shaft 13 away from the motor 12. The gear 14 is meshed with the gear ring 10. When it is necessary to identify vehicle bodies of different widths, the motor 12 is first started to drive the gear 14 to rotate through the output shaft 13. At this time, since the gear 14 is meshed with the gear ring 10 and the gear ring 10 is fixedly connected to the connecting shaft 6, the connecting shaft 6 is rotatably connected to the top of the housing 5. The connecting shaft 6 is also fixedly connected to the fixing rod 7. A fixing block 8 is sleeved on the outside of the fixing rod 7. When the fixing rod 7 rotates, the fixing block 8 can drive the camera 9 to rotate in the lateral angle, thereby increasing the overall recognition width of the camera 9 and achieving the effect of increasing the lateral recognition of the camera 9.
[0041] Finally, since a screw thread plate 15 is fixedly installed on the inner side of the support rod 4, a positioning plate 16 is fixedly installed on the top of the base 1, and a second motor 17 is fixedly installed behind the positioning plate 16, with a screw 18 fixedly installed at the output end of the second motor 17, and the screw 18 meshes with the screw thread plate 15, when multiple vehicles are queuing and need to be identified before entering the area, there may be a situation where the license plate of the following vehicle is obscured by the vehicle in front due to its close proximity, making it impossible to identify. In this case, when the following vehicle needs to enter the area, it may be necessary to... When a vehicle behind reverses, and its rear is blocked by a third vehicle, causing a traffic jam, the starter motor 17 drives the lead screw 18 to rotate, causing the lead screw 18 to engage with the lead screw plate 15. Since the lead screw plate 15 is fixedly connected to the support rod 4, the support rod 4 will move and adjust its position through the sliding action of the slider 3 and the slide groove 2 during the engagement process. This achieves the effect of recognition without reversing, improving vehicle recognition efficiency and preventing traffic jams.
