Description

Technical Field

[0001] This utility model relates to the field of license plate recognition technology, specifically to a novel license plate recognition processing device. Background Technology

[0002] License plate recognition is an important component of modern intelligent transportation systems. The main data storage unit, communication unit, and auxiliary unit are generally referred to as "auxiliary support unit," which provides necessary support and protection to ensure that the entire device can operate stably and efficiently.

[0003] A search revealed the following information: Publication (Announcement) No.: CN206594820U, titled: "A New Type of License Plate Recognition Processing Device," comprising a main body, a display screen, a controller panel, a license plate information input module, and a license plate imaging module. It provides illumination, making the license plate clearer and meeting operational requirements.

[0004] The above technical solution has the following shortcomings;

[0005] In the above solution, due to the small size of the protective housing, it is difficult to separate or remove the internal units or cameras from the protective housing when they are damaged. This brings great difficulties to the maintenance work, especially in a confined space, where maintenance operations are even more inconvenient. In addition, the cameras and internal auxiliary support units in the device are fixed inside the device cavity, making it inconvenient to inspect and maintain the cameras and internal auxiliary support units in daily life. Utility Model Content

[0006] In view of the problems existing in the above-mentioned novel license plate recognition processing device, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a new type of license plate recognition processing device, which solves the problem that in existing license plate recognition processing devices, the camera and internal auxiliary support unit are fixed inside the cavity, making them difficult to separate or remove. Furthermore, due to the small size of the device's housing, it is extremely inconvenient to repair and perform routine maintenance and inspection of the camera and internal auxiliary support unit in a confined space.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A novel license plate recognition processing device includes a base. A drive chamber is fixedly connected to the top of the base via a rotation adjustment mechanism. A protective chamber is fixedly connected to the top of the drive chamber. The inner sidewalls at both ends of the protective chamber are provided with first slots, and sliding plates are slidably connected to each slot. An installation limiting plate is fixedly connected between the two sliding plates. An installation opening is provided at the top of the installation limiting plate, and a square cable protection tube is inserted therein. A recognition camera is fixedly connected to the top of the square cable protection tube. A threaded tube is fixedly connected to one end of the cable protection tube. One end of the threaded tube passes through the installation opening and is threaded with a limiting nut.

[0010] The drive compartment has multiple second slots on both sides of its inner cavity, and multiple heat dissipation sliding mounting plates are slidably connected thereto. An auxiliary support unit is fixedly connected to the surface of the heat dissipation sliding mounting plate. A sealing door is rotatably connected to the side wall of the drive compartment via a hinge. A display screen is fixedly connected to the side wall surface of the sealing door through an opening.

[0011] Preferably, the rotation adjustment mechanism includes a rotation support column, a threaded limit pin, and an adjustment threaded insertion hole. The rotation support column is rotatably connected inside the cavity of the base. One end of the rotation support column passes through the base and is fixedly connected to the bottom of the drive compartment. The side wall of the base has an opening through which the threaded limit pin is inserted. The bottom of the side wall of the rotation support column has multiple adjustment threaded insertion holes, and the threaded limit pin is threadedly connected to one of the adjustment threaded insertion holes.

[0012] Preferably, the heat dissipation sliding mounting plate includes an L-shaped support plate, a limiting slide plate, and heat dissipation mesh holes. Each L-shaped support plate has a limiting slide plate fixedly connected to the top and bottom of its side wall. Both ends of the limiting slide plate are slidably connected to the corresponding second slot. Each L-shaped support plate has multiple heat dissipation mesh holes on one end surface.

[0013] Preferably, the side wall of the protective compartment is rotatably connected to a limiting plate via a hinge, and the side wall of the limiting plate is fixedly connected to a U-shaped clamp, which engages with a threaded pipe.

[0017] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0018] 1. This utility model utilizes an installation limiting plate set between two sliding plates at both ends. By sliding the two sliding plates in the first slot, the recognition camera can be pulled out to separate from the drive compartment. The limiting nut can then be removed by rotation, which facilitates the separation of the recognition camera from the installation limiting plate. This makes it easier to maintain and inspect the recognition camera internally, and also facilitates quick reinstallation after disassembly.

[0019] 2. This utility model utilizes a heat-dissipating sliding mounting plate set in the second slot, which facilitates sliding to the outlet, making it easy to install or disassemble the installation auxiliary support unit, and to maintain and inspect the installation auxiliary support unit.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This utility model discloses a novel license plate recognition processing device.

[0031] Example 1

[0032] This utility model provides, for example Figure 1-5 The novel license plate recognition processing device shown includes a base 1. A drive chamber 2 is fixedly connected to the top of the base 1 via a rotation adjustment mechanism. A protective chamber 3 is fixedly connected to the top of the drive chamber 2. The inner sidewalls at both ends of the protective chamber 3 are provided with first slots 4, and sliding plates 5 are slidably connected to each slot. An installation limiting plate 6 is fixedly connected between the two sliding plates 5. An installation port 7 is provided at the top of the installation limiting plate 6, and a square cable protection tube 8 is inserted therein. A recognition camera 9 is fixedly connected to the top of the square cable protection tube 8. A threaded tube 10 is fixedly connected to one end of the cable protection tube 8. One end of the threaded tube 10 passes through the installation port 7 and is threadedly connected to a limiting nut 11.

[0033] Multiple second slots 12 are provided on both end side walls of the drive chamber 2, and multiple heat dissipation sliding mounting plates 13 are slidably connected thereto. An auxiliary support unit 14 is fixedly connected to the surface of each heat dissipation sliding mounting plate 13. A sealing door 15 is rotatably connected to the side wall of the drive chamber 2 via hinges. A display screen 16 is fixedly connected to the side wall surface of the sealing door 15 through an opening. Using the provided mounting limit plate 6, the camera 9 is slid out by sliding the sliding plates 5 at both ends in the first slot 4, separating it from the drive chamber 2. The limit nut 11 is then removed by rotation, facilitating the separation of the camera 9 from the mounting limit plate 6 and enabling maintenance of the camera 9. The device facilitates internal inspection and allows for quick reinstallation after disassembly. A heat-dissipating sliding mounting plate 13, located in the second slot 12, allows for easy sliding to the exit point, facilitating the installation or disassembly of the installation auxiliary support unit 14, as well as maintenance and inspection. The display screen 16 displays the identified information, thus solving the problems of existing license plate recognition processing devices where the camera and internal auxiliary support unit are fixed inside the cavity, making separation or removal difficult. Furthermore, the small size of the device's housing makes maintenance and routine inspection of the camera and internal auxiliary support unit extremely inconvenient in confined spaces.

[0034] Example 2

[0035] To facilitate rotation adjustment and subsequent limit fixing, such as Figure 1-3 As shown, the rotation adjustment mechanism includes a rotation support column 17, a threaded limit pin 18, and an adjustment threaded insertion hole 19. The rotation support column 17 is rotatably connected inside the cavity of the base 1. One end of the rotation support column 17 passes through the base 1 and is fixedly connected to the bottom of the drive chamber 2. The side wall of the base 1 has an opening through which the threaded limit pin 18 is inserted. The bottom of the side wall of the rotation support column 17 has multiple adjustment threaded insertion holes 19. The threaded limit pin 18 is threadedly connected to one of the adjustment threaded insertion holes 19. The rotation support column 17 facilitates rotation for orientation adjustment. The identification camera 9 on the top is adjusted to a suitable position. The threaded limit pin 18 is threadedly inserted into the corresponding adjustment threaded insertion hole 19 after adjustment, thereby limiting and fixing the rotation support column 17 and the base 1.

[0036] Example 3

[0037] To provide heat dissipation assistance for the auxiliary support unit 14, such as Figure 2 , 4As shown in Figure 5, the heat dissipation sliding mounting plate 13 includes an L-shaped support plate 20, a limiting slide plate 21, and heat dissipation mesh 22. The top and bottom of the side wall of each L-shaped support plate 20 are fixedly connected to the limiting slide plate 21, and the limiting slide plates 21 at both ends are slidably connected to the corresponding second slots 12. Multiple heat dissipation meshes 22 are opened on one end surface of each L-shaped support plate 20. By using the heat dissipation sliding mounting plate 13 composed of L-shaped support plate 20, limiting slide plate 21, and heat dissipation mesh 22, it is convenient to install the auxiliary support unit 14 while providing heat dissipation assistance to the auxiliary support unit 14.

[0038] Example 4

[0039] To prevent the camera 9 from sliding in the protective compartment 3, such as Figure 2 and 4 As shown, the side wall of the protective compartment 3 is rotatably connected to a limit plate 23 via a hinge. A U-shaped clamp 24 is fixedly connected to the side wall of the limit plate 23. The U-shaped clamp 24 is engaged with the threaded pipe 10. The U-shaped clamp 24 is used to engage and fix the threaded pipe 10, thereby preventing the identification camera 9 at the top from sliding in the protective compartment 3.

[0040] Example 5

[0041] To limit and fix the limiting plate 23 and the sealing door 15 after rotation and closing, such as Figure 1 , 2 As shown in Figure 4, limit sockets 25 are fixedly connected to the side walls of the limiting plate 23 and the sealing door 15, and spring pins 26 are fixedly connected to the side walls of the drive chamber 2 and the protective chamber 3. The spring pins 26 at both ends are inserted into the corresponding limit sockets 25. By using the spring pins 26 at both ends to be inserted into the corresponding limit sockets 25, the limiting plate 23 and the sealing door 15 are limited and fixed after rotation and closing.

[0042] Example 6

[0043] To facilitate supplemental lighting for the recognition camera 9 and to make it easier to observe the device's orientation, such as Figure 1-4 As shown, a U-shaped frame 27 is fixedly connected to the bottom of the side wall of the drive compartment 2. Auxiliary lights 28 are fixedly connected to both ends of the U-shaped frame 27. The side wall surfaces of the limiting plate 23 and the sealing door 15 are provided with reflective coatings. The auxiliary lights 28 at both ends of the U-shaped frame 27 are used to provide supplementary lighting for the recognition camera 9. The reflective coating is used to help the driver to notice the location of the reflective device from a distance.

[0044] How to use:

[0045] During installation, the square cable protection tube 8 at the bottom of the identification camera 9 is inserted into the mounting port 7 at the top of the mounting limit plate 6. The limit nut 11 is then threadedly connected to the threaded tube 10, and the bottom of the mounting limit plate 6 is pressed by the limit nut 11 to fix the identification camera 9 to the mounting limit plate 6. The mounting limit plate 6 is then slid into the first slots 4 at both ends, and the limit plate 23 is closed by rotation. The threaded tube 10 is secured by the U-shaped clamps 24 on the side wall to prevent the identification camera 9 from sliding in the protective compartment 3. Each heat dissipation sliding mounting plate 13 is then slid out, and different auxiliary support units 14 are installed on the top of each heat dissipation sliding mounting plate 13. Finally, the sealing door 15 is closed, and the spring pin 26 is inserted into the corresponding limit socket 25 to limit and fix the limit plate 23 and the sealing door 15 after rotation and closure. This allows for easy disassembly of the device by reversing the operation.
