[0023] For the description of the present utility model, non-limiting Figure 1 The marks "front", "rear", "up", "down", "left" and "right" shown in the figure are used to facilitate the understanding of the embodiment and are not intended to limit the present invention. Among them, the front-to-back direction represents the longitudinal direction, the left-to-right direction represents the transverse direction, and the up-down direction represents the vertical direction.
[0024] Figure 1-Figure 5 The embodiment of the license plate recognition device of the utility model is shown, which includes a housing 1, a circuit assembly 2 and a camera assembly 3. The circuit assembly 2 and the camera assembly 3 are arranged in the housing 1. The camera assembly 3 includes a fixing bracket 31 and a camera 32. The camera 32 is arranged on the fixing bracket 31, and the camera 32 is electrically connected to the circuit assembly 2. The fixing bracket 31 includes a main body 311 and a mounting portion 312. The main body 311 is provided with a first opening 3111. The mounting portion 312 extends inwardly along the edge of the first opening 3111, and the mounting portion 312 is enclosed on the outer surface of the camera 32.
[0025] In the utility model, a first opening 3111 is provided on the main body 311 of the fixing bracket 31, and the mounting portion 312 extends inward along the edge of the first opening 3111. When the camera 32 is fixed on the fixing bracket 31, the mounting portion 312 is enclosed on the outer surface of the camera 32 to protect the camera 32.
[0026] In some embodiments, Figure 4 As shown, the mounting portion 312 includes a first extension sub-portion 3121 and a second extension sub-portion 3122. The first extension sub-portion 3121 extends inwardly along the edge of the first opening 3111. The opening area of the first extension sub-portion 3121 gradually decreases. The first extension sub-portion 3121 is in the shape of a trumpet. The second extension sub-portion 3122 extends inwardly along the inner end of the first extension sub-portion 3121. The second extension sub-portion 3122 is enclosed on the outer surface of the camera 32. By setting the first extension sub-portion 3121 in the shape of a trumpet and setting the second extension sub-portion 3122 at the inner end of the first extension sub-portion 3121, when the camera 32 is installed, the second extension sub-portion 3122 is enclosed on the outer surface of the camera 32. The second extension sub-portion 3122 protects the camera 32. The first extension sub-portion 3121 can effectively prevent water from entering the second extension sub-portion 3122, and the waterproof effect is better.
[0027] In some embodiments, Figure 4 As shown, the fixing bracket 31 also includes a connecting portion 313, which extends inward along the bottom of the main body 311, and the connecting portion 313 is used to install an electronic device that communicates with the camera 32. The connection portion 313 is provided to facilitate the connection between the electronic device and the camera 32, making the overall structure more compact.
[0028] In some embodiments, Figure 2 , Figure 3 and Figure 5 As shown, the license plate recognition device further includes a waterproof component 4, which is arranged on the front side of the camera component 3. The waterproof component 4 includes a bottom plate 41 and a waterproof cover 42. The bottom plate 41 is connected to the housing 1, and the waterproof cover 42 extends outward along the surface of the bottom plate 41. By connecting the bottom plate 41 to the housing 1, the waterproof cover 42 is enclosed on the upper side and left and right sides of the bottom plate 41, thereby effectively preventing water from entering the interior of the housing 1, and better protecting the camera component 3.
[0029] In some embodiments, Figure 3-Figure 5 As shown, the bottom plate 41 includes a bottom plate portion 411 and a protruding portion 412. The bottom plate portion 411 is provided with a second opening 4111. The protruding portion 412 extends inward along the edge of the second opening 4111. The protruding portion 412 extends into the interior of the housing 1 and is connected to the main body portion 311. By extending the protruding portion 412 into the interior of the housing 1 and connecting with the main body portion 311, the arrangement of the protruding portion 412 makes the distance between the main body portion 311 and the bottom plate portion 411 greater, thereby better protecting the camera assembly 3 and preventing dust or rainwater outside the housing 1 from damaging the camera assembly 3.
[0030] In some embodiments, Figure 5 As shown, the lower bottom surface of the protrusion 412 is inclined upward at a certain angle to the bottom plate 411. The angle can be 30°, 45° or 60°, etc., as long as an upward inclined surface can be formed between the lower bottom surface of the protrusion 412 and the bottom plate 411. When rainwater flows to the protrusion 412, it will directly flow from the inclined surface to the outside of the housing 1, preventing rainwater from entering the inside of the housing 1 from the protrusion 412, and achieving a better waterproof effect.
[0031] In some embodiments, Figure 5 As shown, the width of the protrusion 412 gradually increases from top to bottom. The width of the upper end of the protrusion 412 is greater than that of the lower end, so that the back of the protrusion 412 is an inclined surface. When the protrusion 412 is connected to the main body 311, the lens of the camera 32 is tilted downward due to the existence of the inclined surface, which facilitates the camera 32 to recognize the license plate.
[0032] In some embodiments, Figure 3-Figure 5As shown, a waterproof protection screen 43 is provided between the protrusion 412 and the main body 311. The waterproof protection screen 43 is a light-transmitting screen. An opening adapted to the waterproof protection screen 43 is provided on the back of the protrusion 412, and the waterproof protection screen 43 is stuck in the opening. By providing the waterproof protection screen 43 between the protrusion 412 and the main body 311, water can be prevented from entering the fixing bracket 31 from the protrusion 412, and the waterproof effect is better.
[0033] In some embodiments, Figure 3 As shown, a camera protection cover 44 is provided on the camera 32. By providing the camera protection cover 44 on the camera 32, the protection effect of the camera 32 is further improved.
[0034] In some embodiments, Figure 3 and Figure 4 As shown, a fixing plate 45 is also provided on the camera protective cover 44, and an opening adapted to the camera protective cover 44 is formed on the fixing plate 45. The fixing plate 45 is stuck on the outer surface of the camera protective cover 44 and is connected to the main body 311. The fixing plate 45 reinforces the camera protective cover 44 to prevent the camera protective cover 44 from falling off.
[0035] In some embodiments, Figure 1 As shown, the top and side of the housing 1 are provided with interconnected rainwater channels 5. Rainwater on the top of the housing 1 will flow along the rainwater channels 5 to the bottom of the housing 1, and a large amount of rainwater will not accumulate on the surface of the housing 1, reducing the risk of rainwater penetrating into the interior of the housing 1, and having a better waterproof effect.
[0036] It can be seen that the utility model discloses a license plate recognition device, including a housing, a circuit assembly and a camera assembly, the circuit assembly and the camera assembly are arranged in the housing, the camera assembly includes a fixing bracket and a camera, the camera is arranged on the fixing bracket, and the camera is electrically connected to the circuit assembly; the fixing bracket includes a main body and a mounting portion, the main body is provided with a first opening, the mounting portion extends inwardly along the edge of the first opening, and the mounting portion is enclosed on the outer surface of the camera.
