[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0028] Please see Figure 1 , Figure 2 and Figure 3This utility model, in a preferred embodiment, provides an integrated barrier gate for license plate recognition, comprising a housing 1, a license plate recognition component 2, an electrical control component 3, a gate core component 4, and a gate arm 5. The license plate recognition component 2, electrical control component 3, and gate core component 4 are all housed within the housing 1. The license plate recognition component 2 is used to recognize license plates. The gate core component 4 is connected to the gate arm 5, allowing the gate arm 5 to switch between horizontal and vertical positions. When the gate arm 5 is in the horizontal position, vehicle passage is prohibited; when the gate arm 5 is in the vertical position, vehicle passage is permitted. The electrical control component 3 is electrically connected to the license plate recognition component 2 and the gate core component 4, used to record license plates and control the operation of the gate core component 4.
[0029] By placing the license plate recognition component 2 inside the housing 1, the license plate recognition component 2 will not change position due to external factors after the angle is adjusted, thus ensuring effective recognition of license plates.
[0030] like Figure 3 As shown, the housing 1 includes a shell 11 and a door 12. The license plate recognition component 2, the gate core component 4, and the electronic control component 3 are arranged vertically within the shell 11. The door 12 is rotatably mounted on the shell 11 with its rotation axis vertical. The top of the door 12 is higher than the license plate recognition component 2, and the bottom is lower than the electronic control component 3, allowing the door 12 to cover the license plate recognition component 2, the gate core component 4, and the electronic control component 3. By rotating the door 12, the housing 1 can be opened, exposing the license plate recognition component 2, the gate core component 4, and the electronic control component 3 for maintenance. A display screen 18 is provided on the door 12 at the position corresponding to the gate core component 4. By mounting the display screen 18 on the door 12, opening the door 12 exposes the back of the display screen 18 for maintenance.
[0031] Combination Figure 1 and Figure 2 As shown, an inner groove 121 is provided on the gate body 12 at the position corresponding to the license plate recognition component 2, and the inner groove 121 is recessed into the housing 1; a light-transmitting plate 13 is provided in the inner groove 121, and the light-transmitting plate 13 is arranged opposite to the groove opening of the inner groove 121. The top of the inner groove 121 has a groove top wall 122 and the bottom has a groove bottom wall 123. Both the groove top wall 122 and the groove bottom wall 123 are inclined in a gradually rising direction from the groove opening of the inner groove 121 to the light-transmitting plate 13, so as to prevent rainwater from flowing towards the light-transmitting plate 13, so that rainwater will not enter the light-transmitting plate 13, thus avoiding affecting the light transmission performance of the light-transmitting plate 13, improving waterproof performance, and ensuring the operational reliability of the integrated gate machine that facilitates license plate recognition.
[0032] like Figure 4 , Figure 5 and Figure 6As shown, a fan 14 is installed on the top wall 122 of the slot. The air outlet of the fan 14 is directed towards the light-transmitting plate 13. The fan 14 blows air onto the light-transmitting plate 13 to eliminate water mist on its surface, ensuring that the license plate recognition component 2 can correctly acquire images and improving the success rate of license plate recognition. Both the fan 14 and the license plate recognition component 2 are electrically connected to the electronic control component 3. When the license plate recognition component 2 malfunctions, the electronic control component 3 activates the fan 14 to defog the light-transmitting plate 13, thus facilitating license plate recognition.
[0033] The fan 14 is fixed to the upper surface of the top wall 122 of the trough. The inclined top wall 122 can prevent external rainwater from wetting the fan 14. Since the top wall 122 of the trough is inclined, the central axis of the fan 14 is perpendicular to the top wall 122 of the trough, which can make the central axis of the fan 14 also inclined and facing the light-transmitting plate 13, thereby blowing air onto the light-transmitting plate 13, which is conducive to the installation of the fan 14.
[0034] A heating module is installed inside the fan 14 to provide hot air and speed up the defogging process.
[0035] An integrated audio module 15 is also installed on the top wall 122 of the channel. The speaker and microphone included in the integrated audio module 15 facilitate communication between management personnel and passersby, and allow for manual registration of license plate information. The integrated audio module 15 is also located on the upper surface of the top wall 122 to prevent external rainwater from wetting it. The integrated audio module 15 is positioned relative to the fan 14 near the opening of the recess 121, bringing it closer to the driver and improving sound transmission.
[0036] The horizontal recess depth of the inner groove 121 is greater than the vertical height of the light-transmitting plate 13, so that the light-transmitting plate 13 is far away from the groove opening of the inner groove 121, thus preventing rainwater from entering the light-transmitting plate 13.
[0037] The light-transmitting plate 13 is arranged adjacent to the top wall 122 of the groove and spaced apart from the bottom wall 123 of the groove, so that the light-transmitting plate 13 is located in the upper corner of the inner groove, which further effectively prevents rain from getting in.
[0038] like Figure 3 As shown, the housing 11 includes a top plate 111. When the door 12 is closed, the top plate 111 is located above the top wall 122 of the slot. When the door 12 is open, the upper surface of the top wall 122 of the slot is exposed, thereby exposing the integrated audio module 15 and the fan 14, so as to facilitate the installation of the integrated audio module 15 and the fan 14 onto the inner surface of the top wall 122 of the slot, and at the same time facilitate the maintenance of the integrated audio module 15 and the fan 14.
[0039] like Figure 6As shown, a baffle 16 is fixed on the lower surface of the groove top wall 122. The baffle 16 is parallel to the groove top wall 122 and the two are in contact. The baffle 16 extends to the outside of the groove opening of the inner groove 121. The baffle 16 can block the rainwater on the outer surface of the door body 12 from the outside of the inner groove 121, and further effectively prevent rainwater from entering the groove top wall 122.
[0040] like Figure 3 , Figure 7 and Figure 8 As shown, the license plate recognition component 2 includes an adjustable bracket 21 and a camera (not shown). The adjustable bracket 21 includes a mounting plate 210, a first angle adjustment plate 211, and a second angle adjustment plate 212. One end of the mounting plate 210 is fixed to the housing 11, and the camera is mounted on the second angle adjustment plate 212. The first angle adjustment plate 211 is mounted on the other end of the mounting plate 210 via a first adjustment bolt 221 and can rotate vertically to adjust the angle of the camera. The second angle adjustment plate 212 is mounted on the first angle adjustment plate 211 via a second adjustment bolt 222 and can rotate horizontally to adjust the angle of the camera. The first angle adjustment plate 211 and the second angle adjustment plate 212 allow the camera to be aligned with the vehicle's license plate at both horizontal and vertical angles, facilitating recognition.
[0041] like Figure 4 , Figure 5 As shown, a supplementary light 19 is also provided on the inner side of the door body 12. A light-transmitting baffle 16 is provided on the door body 12 at the position corresponding to the supplementary light 19, so as to protect the supplementary light 19 from external interference. The supplementary light 19 is located below the display screen 18 so as to illuminate the license plate position of the vehicle.
[0042] This utility model provides an integrated barrier gate for license plate recognition. The top and bottom walls of the channel are both inclined, gradually rising towards the light-transmitting plate to prevent rainwater from flowing towards it and entering, thus avoiding any impact on the light transmittance. A fan is used to blow air onto the light-transmitting plate to eliminate water mist on its surface, ensuring the license plate recognition component can accurately capture images and improving the success rate of license plate recognition.
[0043] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
