[0037] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 and Figure 8 According to the first embodiment of the present invention, the license plate recognition integrated device includes a housing 1, a support platform 2 and a lens assembly 3. The housing 1 is provided with a mounting cavity 16 and a lens hole 11 connected to the mounting cavity 16; the support platform 2 is provided in the mounting cavity 16, and the support platform 2 is provided with a supporting plane 21; the lens assembly 3 is provided in the mounting cavity 16 and is arranged corresponding to the lens hole 11. The lens assembly 3 includes a bracket 31, a pitch plate 32 and a camera component 33. The bracket 31 is rotatably mounted on the supporting plane 21. The frame 31 rotates on the supporting plane 21 to drive the pitch plate 32 and the camera component 33 to swing in the horizontal direction. The pitch plate 32 is rotatably connected to the bracket 31 so that the pitch plate 32 pitches relative to the bracket 31. The camera component 33 is installed on the side of the pitch plate 32 facing the lens hole 11. A circular hole 324 is provided on the side of the pitch plate 32 facing the lens hole 11. The camera component 33 is connected to the pitch plate 32 through the circular hole 324. The camera component 33 can rotate along the extension direction of the circular hole 324.
[0038] It is understood that the support platform 2 can be fixed to the inner wall of the mounting cavity 16 by means of a threaded connection, a snap connection, or the like. Optionally, the support platform 2 is located below the lens hole 11, and the support plane 21 is located on the top surface of the support platform 2 and arranged horizontally, so that when the bracket 31 is installed on the support plane 21, it corresponds to the lens hole 11, facilitating the camera component 33 to shoot outward from the lens hole 11 to identify the license plate. It should be noted that the lens of the camera component 33 can be located within the mounting cavity 16, or it can extend from the lens hole 11 to the outside to avoid being blocked.
[0039] It can be understood that the bracket 31 swings left and right in the horizontal direction on the support plane 21, and the pitch plate 32 can pitch up and down in the vertical direction relative to the bracket 31. At the same time, the camera component 33 rotates on the surface of the pitch plate 32, thereby adjusting the shooting angle in multiple dimensions. In this way, when the license plate recognition integrated machine is installed at an angle or in a special installation position, the shooting angle of the camera component 33 can still be adjusted to make the shooting picture return to the normal state, which is conducive to improving the license plate recognition effect, such as recognition accuracy and recognition efficiency. The rotational connection between the bracket 31 and the support plane 21, the rotational connection between the pitch plate 32 and the bracket 31, and the rotational connection between the camera component 33 and the pitch plate 32 can all be achieved through connecting shafts.
[0040] In one embodiment, a fill light component 34 is provided on the side of the pitch plate 32 facing the lens hole 11. The fill light component 34 may have a through hole for the lens of the camera component 33 to pass through. The fill light component 34 may provide light to improve the shooting clarity.
[0041] According to the license plate recognition integrated machine of the embodiment of the present invention, the mounting cavity 16 of the housing 1 is used to mount the support platform 2 and the lens assembly 3. The lens assembly 3 can shoot outward through the lens hole 11 of the housing 1 to recognize the license plate. The bracket 31 is rotatably supported on the supporting plane 21, thereby driving the camera component 33 to swing left and right for shooting, which is convenient for adjusting the shooting area. At the same time, the pitch plate 32 can be rotated relative to the bracket 31 to pitch, and the camera component 33 can be driven to pitch by the pitch plate 32 to adjust the shooting height. In addition, the camera component 33 can also rotate along the annular hole 324 of the pitch plate 32 to adjust the shooting angle. In this way, the camera component 33 can adjust the shooting angle from multiple dimensions to improve the license plate recognition effect.
[0042] For example, the all-in-one license plate recognition machine adopts an integrated design with no exposed modules. The camera component 33 can adopt a 500W pixel high-definition license plate recognition camera. The camera debugging angle range is improved through reasonable structural design. At the same time, effective recognition and judgment are taken for vehicle detention and return events to adapt to more application scenarios. The product stability and reliability are improved through reasonable internal design, and the interference caused by external factors is reduced, thereby improving the overall parking lot management efficiency.
[0043] like Figure 8 As shown, according to one embodiment of the present invention, the pitch plate 32 is provided with an arcuate hole 321, and the bracket 31 is provided with a support rod (not shown in the figure). The support rod is movably inserted into the arcuate hole 321. When the pitch plate 32 is pitched, the support rod moves along the arcuate hole 321. It will be understood that in order to facilitate the pitching of the pitch plate 32, by inserting the support rod into the arcuate hole 321, the support rod can limit the rotation of the pitch plate 32 when the pitch plate 32 rotates, thereby better supporting the rotation of the pitch plate 32 and preventing the pitch plate 32 from shifting.
[0044] According to one embodiment of the present invention, the bracket 31 is provided with a first support portion 311 and a second support portion 312 spaced apart from each other, each of which is provided with a support rod, and the pitch plate 32 is provided with a first connection portion 322 and a second connection portion 323 spaced apart from each other, each of which is provided with an arc-shaped hole 321, with each support rod passing through an arc-shaped hole 321. It will be understood that the first support portion 311 and the second support portion 312 are provided on either side of the bracket 31, and the first connection portion 322 and the second connection portion 323 are provided on either side of the pitch plate 32, to ensure that both sides of the pitch plate 32 and both sides of the bracket 31 are subjected to uniform force, thereby improving installation stability.
[0045] According to one embodiment of the present invention, the rotation angle of the bracket 31 is greater than 90°, that is, when the bracket 31 is rotated to the left extreme position and the right extreme position, the angle formed with the rotation center is greater than 90°, so as to ensure a good left and right shooting angle. Optionally, the pitch angle of the pitch plate 32 is greater than 90°, that is, when the pitch plate 32 is rotated to the upper extreme position and the lower extreme position, the angle formed with the rotation center is greater than 90°, so as to ensure a good upper and lower shooting angle. Optionally, the rotation angle of the camera component 33 is greater than 90°. It can be understood that the camera component 33 rotates to adjust the inclination of the shooting picture to ensure that the shooting picture is horizontal or at an angle that is convenient for identifying the license plate.
[0046] Please refer to Figure 4 and Figure 5 According to one embodiment of the present invention, the license plate recognition integrated device includes a first waterproof cover 12, which covers the inner wall of the installation cavity 16 and encloses the inner wall of the installation cavity 16 to form a first waterproof cavity 121. The first waterproof cover 12 is provided with a sound outlet 122 connected to the first waterproof cavity 121, and the sound outlet 122 is used to install a speaker. The outer wall of the housing 1 is provided with a first arc-shaped protrusion 13, and the bottom of the first arc-shaped protrusion 13 is provided with a first communication port 131 connected to the first waterproof cavity 121.
[0047] Exemplarily, the outer wall of the housing 1 is provided with a plurality of first arc-shaped protrusions 13 arranged at intervals in the vertical direction. The upper surface and the side surface of the first arc-shaped protrusions 13 are connected to form an outwardly protruding arc surface to guide rainwater to flow away from the housing 1. At the same time, a first communication port 131 is provided at the bottom of the first arc-shaped protrusion 13, from which sound can be transmitted, and rainwater is not easy to enter the installation cavity 16 through the first communication port 131. In addition, a first waterproof cover 12 is installed in the installation cavity 16 at a position corresponding to the first arc-shaped protrusion 13. The first waterproof cover 12 covers the first communication port 131. That is, even if rainwater enters from the first communication port 131, it will first enter the first waterproof cavity 121 formed by the first waterproof cover 12 and the inner wall of the installation cavity 16, and will not cause the components in the installation cavity 16 to come into contact with water, thereby improving the waterproof effect. Furthermore, the first waterproof cover 12 is provided with a sound hole 122, and a speaker can be installed corresponding to the sound hole 122 to release the sound from the first communication port 131 through the first waterproof cavity 121. The first waterproof cavity 121 can serve as a sound cavity to improve the sound effect of the speaker.
[0048] Please refer to Figure 4 and Figure 6 According to one embodiment of the present invention, the license plate recognition integrated device includes a second waterproof cover 14, which covers the inner wall of the installation cavity 16 and encloses the inner wall of the installation cavity 16 to form a second waterproof cavity 141. The second waterproof cover 14 is provided with a plurality of heat dissipation holes 142 connected to the second waterproof cavity 141. The outer wall of the housing 1 is provided with a second arc-shaped protrusion 15, and the bottom of the second arc-shaped protrusion 15 is provided with a second communication port 151 connected to the second waterproof cavity 141.
[0049] For example, the outer wall of the housing 1 is provided with a plurality of second curved protrusions 15 arranged at intervals in the vertical direction. The upper and side surfaces of the second curved protrusions 15 are connected to the outwardly convex curved surface to guide rainwater away from the housing 1. A second communication opening 151 is provided at the bottom of the second curved protrusions 15, through which heat within the mounting cavity 16 can be transferred, preventing rainwater from entering the mounting cavity 16 through the second communication opening 151. Furthermore, a second waterproof cover 14 is installed within the mounting cavity 16 at a position corresponding to the second curved protrusions 15. The second waterproof cover 14 covers the second communication opening 151. In other words, even if rainwater enters through the second communication opening 151, it will first enter the second waterproof cavity 141 formed by the second waterproof cover 14 and the inner wall of the mounting cavity 16, preventing the components within the mounting cavity 16 from being exposed to water, thereby improving the waterproof effect. Furthermore, the second waterproof cover 14 is provided with a plurality of heat dissipation holes 142, which can have a louvered structure to improve heat dissipation. The heat in the mounting cavity 16 is released from the heat dissipation holes 142 through the second waterproof cavity 141 and out of the first communication port 131 .
[0050] According to one embodiment of the present invention, the first waterproof cover 12 and the first arc-shaped protrusion 13 are provided on one side of the housing 1, and the second waterproof cover 14 and the second arc-shaped protrusion 15 are provided on the other side of the housing 1. It can be understood that one side of the housing 1 serves as the sound output side, where a speaker or other structure can be installed, while the other side of the housing 1 serves as the heat dissipation side to ensure heat dissipation, and the two sides do not affect each other.
[0051] According to one embodiment of the present invention, the license plate recognition integrated device includes at least two first waterproof covers 12, and the outer wall of the housing 1 is provided with at least two first arc-shaped protrusions 13, with each first waterproof cover 12 corresponding to a first arc-shaped protrusion 13. It is understood that the housing 1 can be provided with multiple sound output positions to ensure the sound output effect.
[0052] According to one embodiment of the present invention, the license plate recognition integrated device includes at least two second waterproof covers 14, and the outer wall of the housing 1 is provided with at least two second curved protrusions 15, with each second waterproof cover 14 corresponding to a second curved protrusion 15. It is understood that the housing 1 can be provided with multiple heat dissipation positions to ensure effective heat dissipation.
[0053] like Figure 2 As shown, according to one embodiment of the present invention, the integrated license plate recognition device further includes a wiring structure 4, which is mounted on the inner wall of the mounting cavity 16. The wiring structure 4 defines a wiring groove for accommodating and limiting the wiring within the mounting cavity 16. It will be appreciated that by installing the wiring structure 4 on the inner wall of the mounting cavity 16, there is no need to define a separate wiring groove on the inner wall of the mounting cavity 16, which can enhance the strength of the housing 1.
[0054] Finally, it should be noted that the above embodiments are intended only to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be encompassed by the claims of the present invention.
