Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a box structure, in particular to a box structure of a high-definition license plate recognition all-in-one machine. Background Art
[0002] Currently, license plate recognition cameras used in parking lots and other locations include devices with separate license plate cameras and cameras, as well as all-in-one systems where the license plate recognition camera and the camera are integrated into a single housing. All-in-one systems are becoming increasingly popular because they integrate all necessary components. They are primarily used at entrances and exits of residential parking lots, shopping mall parking lots, and hotel parking lots. They can be installed indoors or outdoors, offering convenient management and a more upscale feel. Generally, a camera, display screen, and license plate recognition spotlight need to be installed on an all-in-one machine. However, in actual use, the traditional all-in-one machine box structure has some problems that need to be solved, as follows: (1) The box body of the all-in-one machine is generally a square box structure with columns. After the camera is installed inside, the camera glass surface in front of the camera and the display screen often form the same vertical plane, and rely entirely on the skirt or roof-like components that slightly extend outward from the top of the box body to block light or rain. Such a shielding method fails to effectively block rain from hitting the camera glass surface, affecting the camera effect and the success rate of license plate recognition, and easily misidentifying the license plate. In addition, due to the small shielding area and the lack of compactness, it is difficult to efficiently and accurately identify the license plate when sunlight, car headlights, etc. directly hit the camera glass surface, that is, it cannot effectively suppress the front light and backlight from shining on the camera glass surface. (2) When used at night or in a dark environment, the ultra-high brightness of the license plate recognition spotlight (i.e., full-color lamp bead spotlight, etc.) is often used to illuminate the car license plate in order to accurately identify the license plate. When using all-in-one devices outdoors, not only can rain dampen the camera glass and license plate recognition studs, affecting license plate recognition accuracy, but also, due to insufficient or no shielding, leaves, branches, paper scraps, plastic bags, and other objects can easily cling to or obstruct license plate recognition in windy and rainy weather, seriously affecting license plate recognition. Furthermore, many existing parking lot entrances and exits for automatic payment and license plate recognition no longer have staff, instead using automated payment methods like WeChat, Alipay, or contactless payment. When this occurs, the only options are for staff to arrive or for the driver to exit the vehicle. While staff arrive, this can easily cause a long queue of cars behind, leading to severe traffic congestion. If drivers exit the vehicle to handle the issue themselves, their clothing will get wet in the harsh, windy and rainy weather, even with an umbrella.
[0003] In view of the above situation, in order to solve the technical problems such as the box structure of the all-in-one machine in the existing technology, there is still room for improvement and solution. Summary of the Invention

[0025] In this embodiment 1, the first side panel is mounted on one side of the front panel and forms a right angle with the top, and the protruding side of the first side panel is wavy. The design of the first side panel not only provides shielding but also has a graceful sense of lines, enhancing the overall sense of class.
[0026] In this embodiment 1, the protruding covering seat includes a second square plate 15 with a top protruding outward, and second side plates 16 with two bottom sides of the second square plate extending downward and covering both sides of the spotlight installation opening.
[0027] In this embodiment 1, the second side block plate is a square plate, and the bottom of the second side block plate is an inclined surface that gradually slopes downward from the outside to the inside.
[0028] In this embodiment 1, the voice transmission port is composed of two inner and outer circles of voice transmission holes distributed in a ring array.
[0029] In this embodiment 1, the transverse cross-section of the front panel is a trapezoid that gradually widens inward, and the camera mounting opening and the display mounting opening are both recessed inward on the front panel.
[0030] In this embodiment 1, a load-bearing base 17 is further provided at the bottom of the base plate for bearing and supporting the base plate.
[0031] In this embodiment 1, the box structure of the high-definition license plate recognition integrated machine adopts a column box method, and a protruding light suppression seat with a covering function and a protruding setting is provided on the top and outside of the camera installation port, which can effectively suppress the front light and back light, ensure excellent automatic imaging and recognition, and realize accurate license plate recognition function; at the same time, a protruding covering seat is also provided on the top and outside of the spotlight installation port to prevent rain or leaves and branches from blocking the light emitted by the spotlight, ensuring ultra-high brightness light emission and ensuring accurate license plate recognition; finally, the overall box structure is in the form of a column, and the overall front panel part is a trapezoidal vertical shape, which can make the entire box structure present a strong three-dimensional sense and high-end sense.
[0032] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation on the technical solution of the present invention. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
