[0014] See also Figure 1-2 , the utility model provides a technical solution:

[0015] In order to improve the safety of the vehicle, an anti-collision automatic parking device for a refueling truck is proposed, which includes a housing 1, a transmission component 2, a parking component 3, a controller 4, and a laser rangefinder 5. The housing 1 is installed at the front end of the vehicle body, the transmission component 2 is installed inside the housing 1, one end of the parking component 3 is hinged with the transmission component 2, and the other end of the parking component 3 is hinged with the brake pedal 6. The parking component 3 is installed in the housing 1, the controller 4 is fixedly installed in the housing 1, the laser rangefinder 5 is fixedly installed on the outside of the housing 1, the controller 4 is connected to the alarm 7, the alarm 7 is fixedly installed in the housing 1, the controller 4 controls the transmission component 2 and the parking component 3 to work, the controller 4 receives the signal information fed back by the laser rangefinder 5, and the distance threshold is set in the controller 4, and the distance threshold is 0.8 meters. When the distance information fed back by the laser rangefinder 5 exceeds the threshold, the controller 4 controls the alarm 7 to emit a buzzing alarm sound, and the controller 4 controls the transmission component 2 and the parking component 3 to work.

[0016] The transmission assembly 2 includes: an electric telescopic rod 201, a connecting rod 202, a first slider 203, a first slide groove 204, a first movable rod 205, and a transmission wheel 206. One end of the electric telescopic rod 201 is connected to the controller 4, and the controller 4 can control the electric telescopic rod 201 to extend and retract. The electric telescopic rod 201 adopts an existing product, and the motor and the telescopic rod in the electric telescopic rod 201 do not have a locking function.

[0017] The other end of the electric telescopic rod 201 is fixedly connected to one end of the connecting rod 202, and the other end of the connecting rod 202 is fixedly connected to one side of the first slider 203. The first slider 203 is slidably installed in the first slide groove 204, and the first slide groove 204 is fixedly installed in the housing 1. The extension and retraction of the electric telescopic rod 201 will drive the connecting rod 202 to move in the same direction, and the connecting rod 202 pushes the first slider 203 to slide in the first slide groove 204;

[0018] One end of the first movable rod 205 is hinged on the other surface of the first slider 203, and the other end of the first movable rod 205 is hinged to the wheel surface of the transmission wheel 206. The transmission wheel 206 is rotatably installed in the shell 1. When the first slider 203 slides in the first slide groove 204, the hinged end of the first movable rod 205 and the first slider 203 moves with the movement of the first slider 203. The other end of the first movable rod 205 starts to move under the push of the first slider 203. The other end of the first movable rod 205 is hinged to the transmission wheel 206. The hinge point between the other end of the first movable rod 205 and the transmission wheel 206 is at the bottom of the surface of the transmission wheel 206. Therefore, the first movable rod 205 pushes the transmission wheel 206 to rotate counterclockwise, and one end of the parking component 3 is hinged on the wheel surface of the transmission wheel 206.

[0019] The parking assembly 3 includes a second movable rod 301, a second slider 302, a second slide groove 303, and a brake rod 304. One end of the second movable rod 301 is hinged to the surface of the transmission wheel 206, and the other end of the second movable rod 301 is fixedly connected to the second slider 302. The second slider 302 is slidably installed in the second slide groove 303, and the second slide groove 303 is fixedly installed in the housing 1. The second slider 302 is hinged to one end of the brake rod 304, and the other end of the brake rod 304 is hinged to the brake pedal 6. When the transmission wheel 206 rotates counterclockwise, the second movable rod 301 and the transmission wheel 206 rotate counterclockwise. The hinged end on the surface of the wheel 206 rotates counterclockwise accordingly, and the hinged end of the second movable rod 301 on the surface of the transmission wheel 206 and the hinged end of the first movable rod 205 on the transmission wheel 206 are on the same diameter. When the first movable rod 205 rises, the second movable rod 301 descends, and one end of the second movable rod 301 descends, pulling the second slider 302 to slide downward in the second slide groove 303, and the brake rod 304 hinged to the second slider 302 moves downward as a whole, and the brake rod 304 pulls the brake pedal 6 down, and the brake pedal 6 is connected to the vehicle's brake system, and the vehicle brakes.

[0020] Working principle:

[0021] When the distance information fed back by the laser rangefinder 5 exceeds the threshold, the controller 4 controls the alarm 7 to emit a buzzer alarm sound, and the controller 4 controls the transmission component 2 and the parking component 3 to work.

[0022] The controller 4 can control the electric telescopic rod 201 to extend and retract. The extension and retraction of the electric telescopic rod 201 will drive the connecting rod 202 to move in the same direction. The connecting rod 202 pushes the first slider 203 to slide in the first slide groove 204. When the first slider 203 slides in the first slide groove 204, the hinged end of the first movable rod 205 and the first slider 203 moves with the movement of the first slider 203. The other end of the first movable rod 205 starts to move under the push of the first slider 203. The other end of the first movable rod 205 is hinged to the transmission wheel 206. The hinge point of the other end of the first movable rod 205 and the transmission wheel 206 is at the bottom of the surface of the transmission wheel 206, so the first movable rod 205 pushes the transmission wheel 206 to rotate counterclockwise.

[0023] When the transmission wheel 206 rotates counterclockwise, the second movable rod 301 and the hinged end of the transmission wheel 206 rotate counterclockwise, the second movable rod 301 descends, one end of the second movable rod 301 descends, and the second slider 302 slides downward in the second slide groove 303, and the brake rod 304 hinged to the second slider 302 moves downward as a whole, and the brake rod 304 pulls the brake pedal 6 down, and the brake pedal 6 is connected to the vehicle brake system, and the vehicle brakes. After the vehicle stops, the electric telescopic rod 201 shrinks, the transmission wheel 206 rotates counterclockwise, and the second slider 302 slides upward in the second slide groove 303, and the brake rod 304 pulls the brake pedal 6 up, and the brake pedal 6 is restored.

[0024] The electric telescopic rod 201 is a product without a locking function. Therefore, when the driver normally brakes the vehicle and there is no energy supply from the electric telescopic rod 201, the transmission assembly 2 and the parking assembly 3 can freely operate in the reverse direction. Only when the distance between the obstacle and the vehicle is less than 0.8 meters, the controller 4 controls the electric telescopic rod 201 to supply energy to assist the driver in parking.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
