It is generally used in parking lots or important intersections. With the popularization of cars, most parking lots use license plate recognizers to effectively and standardizedly manage vehicles entering and leaving the parking lot.

[0003] The license plate recognition device is mainly composed of components such as a chassis and a barrier railing. In actual use, due to the simple structure of the barrier railing, it is difficult for some novice drivers to accurately judge the distance between the front of the vehicle and the barrier railing.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 An anti-collision license plate reader includes a chassis 1, a barrier railing 2 is connected to the side of the chassis 1, and a slide bar 3 is symmetrically inserted inside the barrier railing 2. The connection method and working principle of the chassis 1 and the barrier railing 2 are prior art and will not be repeated here. The front of the slide bar 3 is connected through a blocking rod 4, the back of the slide bar 3 is connected to a connecting block 5, and the front of the connecting block 5 is connected to the barrier railing 2 through a first spring 6.

[0023] Further, see Figure 1 , Figure 2 and Figure 3 It can be known that the bottom end of the barrier rod 4 is symmetrically connected with a toothed plate 7, a support frame 8 is installed on the back of the barrier railing 2, and a gear 9 is provided on the outer side of the support frame 8 through a bearing sleeve, the outer side of the gear 9 is meshed with the toothed plate 7, and a movable plate 10 is equidistantly sleeved on the outer side of the barrier railing 2, and the back of the movable plate 10 is evenly distributed with teeth matching the gear 9, an impact ball 11 is connected to the upper side of the movable plate 10, and a metal plate 14 is provided above the impact ball 11. When the barrier rod 4 is moved under force, the toothed plate 7 can drive the gear 9 to rotate, so that the three groups of movable plates 10 are lifted up and approach and knock against the metal plate 14 to remind the driver.

[0024] Further, see Figure 4 It can be known that the upper side of the barrier railing 2 is symmetrically distributed with columns 12, and the top ends of the columns 12 are connected to the sleeve rod 13 through the second spring 15, the upper side of the metal plate 14 is connected to the bottom end of the sleeve rod 13, and the inside of the metal plate 14 is provided with a slide groove adapted to the column 12. Through the slide groove provided inside the metal plate 14, it can slide along the outer surface of the column 12 when subjected to force. Through the mutual cooperation of the sleeve rod 13 and the second spring 15, the force exerted on the metal plate 14 can be buffered, thereby achieving protection of the metal plate 14 and providing a certain amount of activity space for the metal plate 14 so that the driver can brake in time.

[0025] Further, see Figure 2 and Figure 3 It can be known that a rectangular groove is provided on the inner wall of the movable plate 10, and a rectangular bar 16 is embedded inside the rectangular groove. The side of the rectangular bar 16 is fixedly connected to the barrier railing 2. Through the mutual cooperation of the rectangular bar 16 and the rectangular groove, the guiding work of the three groups of movable plates 10 can be realized, thereby ensuring the stability of the movable plate 10 during the movement process.

[0026] Further, see Figure 1 and Figure 2 It can be known that a connecting sleeve is provided at the bottom end of the column 12, and the bottom end of the connecting sleeve is connected to the barrier railing 2, and the interior of the connecting sleeve is connected to the column 12 by bolts. Through the cooperation between the connecting sleeve and the bolts, the staff can easily remove the column 12 from the top of the barrier railing 2 for replacement and maintenance.

[0027] Further, see Figure 1 and Figure 2 It can be known that a movable groove smaller than the outer diameter of the sliding rod 3 is opened inside the barrier railing 2, and a rubber sleeve is glued to the inner wall of the movable groove. The inner wall of the rubber sleeve is tightly fitted with the outer wall of the sliding rod 3. The rubber sleeve is not shown in the figure. By abutting the rubber sleeve against the outer wall of the sliding rod 3, the resistance of the sliding rod 3 during movement can be increased, thereby enhancing the buffering effect on the barrier rod 4.

[0028] Further, see Figure 2 and Figure 4 It can be seen that a rubber strip is glued to the front of the barrier rod 4, and a buffer sleeve is glued to the outer wall of the impact ball 11. The rubber strip and the buffer sleeve are not shown in the figure. Both are made of rubber material. The connection of the rubber strip can effectively prevent the front of the barrier rod 4 from hard contact with the front of the vehicle, thereby preventing the front of the vehicle from being scratched. The buffer sleeve connected to the outer wall of the impact ball 11 can protect the impact ball 11.

[0029] Working principle: When the utility model is in use, the staff can first install the chassis 1 at a suitable position in the parking lot. When some new drivers cannot judge the distance between the front of the car and the device and a collision occurs, the front of the car will first contact the barrier rod 4. At this time, the slide bar 3 connected to the back of the barrier rod 4 can be forced to slide inside the gate railing 2, so that the barrier rod 4 can be forced to move. When the barrier rod 4 moves, the tooth plate 7 can be driven to move at the same time. Since the tooth plate 7 and the gear 9 are meshed, the gear 9 can be forced to rotate. Since the back of the moving plate 10 is distributed with teeth, The teeth are meshed with the gear 9, so when the gear 9 rotates, the three groups of movable plates 10 can be lifted up. At this time, the impact ball 11 connected to the top of the movable plate 10 can hit the metal plate 14 to make a sound, so as to warn and remind the new driver. When the metal plate 14 is hit, the sleeve rod 13 and the second spring 15 cooperate with each other, while protecting the metal plate 14, a certain activity space can be provided for the metal plate 14, so that the driver can brake in time to prevent the collision from continuing. The above is the entire working principle of the utility model.

[0030] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0031] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
