Detailed Implementation Modes

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution: an adjustable license plate recognition probe device, including a base 1, an adjustment mechanism 2, a first worm 201, a first worm gear 202, a bearing 203, a second worm 204, a second worm gear 205, a collar 206, a first bevel gear 207, a second bevel gear 208, a rotating shaft 209, a connecting member 3, a probe body 4, a cleaning mechanism 5, an "L"-shaped rod 501, a first motor 502, a cleaning cotton 503, a connecting component 6, a magic tape surface 601, a magic tape hair surface 602, a first mounting shell 7, a second mounting shell 8, a second motor 9, a third motor 10, and a display screen 11;

[0025] The adjustable license plate recognition probe device is provided with an adjustment mechanism 2. The adjustment mechanism 2 includes a first worm 201, a first worm gear 202, a bearing 203, a second worm 204, a second worm gear 205, a collar 206, a first bevel gear 207, a second bevel gear 208, and a rotating shaft 209. When the angle of the probe body 4 needs to be adjusted, the second motor 9 fixedly installed on the left side in the second mounting shell 8 is started. The output end of the second motor 9 is fixedly installed with a first worm 201. The second motor 9 drives the first worm 201 to rotate. The first worm 201 is meshed and connected with a first worm gear 202. The rotating first worm 201 drives the first worm gear 202 to rotate. The top end of the first worm gear 202 is fixedly connected with a bearing 203. The rotating first worm gear 202 drives the bearing 203 to rotate. The top end of the bearing 203 is fixedly connected with a first bevel gear 207. The rotating bearing 203 drives the first bevel gear 207 to rotate. The first bevel gear 207 is meshed and connected with a second bevel gear 208. The rotating first bevel gear 207 drives the second bevel gear 208 to rotate. The second bevel gear 208 is fixedly installed with a rotating shaft 209, and the rotating shaft 209 is rotatably connected in the first mounting shell 7. The rotating second bevel gear 208 drives the rotating shaft 209 to rotate. The outer side of the rotating shaft 209 is fixedly installed with a connecting member 3. The rotating shaft 209 drives the connecting member 3 to perform a circular motion with its length as the radius and the connection end with the rotating shaft 209 as the center of the circle. The top end of the connecting member 3 is fixedly installed with a probe body 4. The connecting member 3 drives the probe body 4 to perform a circular motion, thereby adjusting its upward viewing and downward viewing angles;

[0026] When it is necessary to adjust the direction of the probe body 4, the third motor 10 fixedly installed on the right side inside the second mounting shell 8 is started. A second worm 204 is fixedly connected to the output end of the third motor 10. The third motor 10 drives the second worm 204 to rotate. The second worm 204 is meshed with a second worm gear 205. The rotating second worm 204 drives the second worm gear 205 to rotate. The second worm gear 205 is fixedly connected to the outer side of the bottom of the collar 206. The second worm gear 205 drives the collar 206. The top of the collar 206 is fixedly connected to the first mounting shell 7. The rotating collar 206 drives the first mounting shell 7 to rotate. The first mounting shell 7 drives the rotating shaft 209 to rotate. The rotating shaft 209 drives the probe body 4 to rotate. A display screen 11 is fixedly installed on the front side of the outer end of the first mounting shell 7. The first mounting shell 7 drives the display screen 11 to rotate, so that the probe body 4 and the display screen 11 can be in the same direction. Since the arc surface at the outer top of the bearing 203 is rotationally connected to the first mounting shell 7, at the same time, the second motor 9 is started in the reverse direction, so that the second motor 9 drives the bearing 203 to rotate, and the first bevel gear 207 rotates following the first mounting shell 7. Therefore, the second bevel gear 208 will not be driven to rotate by the first bevel gear 207. This function is to avoid damage to the first worm 201, the first worm gear 202, the first bevel gear 207 and the second bevel gear 208. Since the bearing 203 is rotationally connected inside the collar 206 and the collar 206 is rotationally connected inside the second mounting shell 8, the direction adjustment and the angle adjustment of the probe body 4 do not interfere with each other;

[0027] The adjustable license plate recognition probe device is provided with a cleaning mechanism 5, as Figure 3 and Figure 4 shown. The cleaning mechanism 5 includes an "L"-shaped rod 501, a first motor 502 and a cleaning cotton 503. When there is dust blocking the line of sight of the lens of the probe body 4, the first motor 502 fixedly installed on the top right side of the first mounting shell 7 is started. A first motor 502 is fixedly connected to the output end of the "L"-shaped rod 501. The first motor 502 drives the "L"-shaped rod 501 to perform a circular motion with the length of the vertical rod of the "L"-shaped rod 501 as the radius and the connection end of the "L"-shaped rod 501 and the first motor 502 as the center of the circle. The inner side of the top of the "L"-shaped rod 501 is connected with a cleaning cotton 503 through a connecting component 6. The "L"-shaped rod 501 drives the cleaning cotton 503 to perform a circular motion, so that the cleaning cotton 503 wipes the lens of the probe body 4;

[0028] The adjustable license plate recognition probe device is provided with a connection component 6. The connection component 6 includes a magic tape sticky surface 601 and a magic tape fluffy surface 602. When it is necessary to disassemble, replace, and clean the cleaning cotton 503, the reverse side of the magic tape sticky surface 601 is fixedly installed on the inner side of the top end of the "L"-shaped rod 501. The cleaning cotton 503 is fixedly installed on the reverse side of the magic tape sticky surface 601. The front side of the magic tape sticky surface 601 is connected to the front side of the magic tape fluffy surface 602. Start the first motor 502 to rotate the cleaning cotton 503 away from the front side of the lens of the probe body 4. Then hold the cleaning cotton 503 and pull it in the opposite direction of the "L"-shaped rod 501 to separate the front side of the magic tape sticky surface 601 from the front side of the magic tape fluffy surface 602, so as to disassemble the cleaning cotton 503. When installing a new cleaning cotton 503, directly press the magic tape fluffy surface 602 on the back of the cleaning cotton 503 against the magic tape sticky surface 601 inside the "L"-shaped rod 501 to connect the front side of the magic tape sticky surface 601 and the front side of the magic tape fluffy surface 602.
