[0002] As people's living standards continue to improve, cars have gradually entered thousands of households and become an irreplaceable means of transportation. The rapid development of the automobile industry has brought new problems to people and has also led to an increase in traffic accidents.
[0003] When people ride bicycles, electric vehicles or motorcycles in the city and pass by cars parked on the road, sometimes the drivers do not pay attention to the vehicles behind them, which can easily cause the car door to open suddenly, making it difficult for the cyclists to dodge and cause the cyclists to collide with the car door, which can easily cause injuries to the cyclists and the overall anti-collision ability is poor.
[0004] For this reason we propose a collision-proof cab door. Utility Model Content
[0005] The purpose of the utility model is to provide an anti-collision cab door in order to improve the anti-collision capability of the door body.
[0006] The technical solutions adopted in this utility model are as follows:
[0007] A collision-resistant cab door comprises a door body and a vehicle body underframe disposed at the lower end of the door body, a controller being mounted inside the door body, an infrared sensor being mounted on the outer surface of the door body, an output end of the infrared sensor being electrically connected to the controller, a mounting groove being formed on the lower surface of the door body, a door locking mechanism being mounted on the inner wall of the mounting groove, and a socket being formed on the upper surface of the vehicle body underframe adjacent to the mounting groove;
[0008] The door locking mechanism includes an electric cylinder, which is fixedly connected to the top inner wall of the mounting groove. The input end of the electric cylinder is electrically connected to the controller. A piston rod is installed on the lower surface of the electric cylinder. A clamping column is fixedly connected to the end of the piston rod away from the electric cylinder. The end of the clamping column away from the piston rod is plugged into the inner surface of the socket.
[0009] Furthermore, a window is provided at the upper end of the door body, and a partition is fixedly connected between the top inner wall and the bottom inner wall of the window.
[0010] Furthermore, a sound and light alarm is installed on a side of the partition close to the interior of the vehicle, and an input end of the sound and light alarm is electrically connected to the controller.
[0011] Furthermore, a rubber pad is bonded to the outer surface of the clamping column, and a plurality of deformation holes are evenly arranged inside the rubber pad.
[0012] Furthermore, the outer diameter of the rubber pad is smaller than the inner diameter of the jack.
[0013] Furthermore, the controller, the sound and light alarm, the infrared sensor and the input end of the electric cylinder are electrically connected to the power supply in the vehicle.
[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0015] In the utility model, when the car is parked, the infrared sensor can sense and measure the distance to the surrounding vehicles and feed the data back to the controller. If the vehicle coming from behind is close and at a dangerous distance, the controller will control the electric cylinder to start so that the piston rod drives the clamping column to move downward. The clamping column moving downward will be inserted into the socket and stuck. At this time, the driver in the cab cannot open the car door to avoid the car door colliding with the vehicle coming from behind. The cooperation of the above structure can improve the anti-collision ability of the car door body. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention. Example
[0022] Reference Figures 1-4 , a collision-proof cab door, comprising a door body 1 and a body chassis 2 arranged at the lower end of the door body 1, a controller 3 is installed inside the door body 1; specifically, the controller 3 adopts a single-chip microcomputer as the main control chip, whose model is STC89C51; an infrared sensor 5 is installed on the outer surface of the door body 1; specifically, the model used by the infrared sensor 5 is EX-BNGRRB587DJ; the output end of the infrared sensor 5 is electrically connected to the controller 3, the lower surface of the door body 1 is provided with a mounting groove 13, the inner wall of the mounting groove 13 is provided with a door locking mechanism 6, and the upper surface of the body chassis 2 near the mounting groove 13 is provided with a socket 21; specifically, in the parking state, the infrared sensor 5 can sense and measure the distance to the surrounding vehicles and feed back the data to the controller 3. If the distance of the vehicle coming from behind is close and in a dangerous distance, the controller 3 will control the door locking mechanism 6 to perform an anti-collision operation.
[0023] Reference Figures 1-4 The door locking mechanism 6 includes an electric cylinder 61, which is fixedly connected to the top inner wall of the mounting groove 13. The input end of the electric cylinder 61 is electrically connected to the controller 3. A piston rod 62 is installed on the lower surface of the electric cylinder 61. The end of the piston rod 62 away from the electric cylinder 61 is fixedly connected to a card column 63. The end of the card column 63 away from the piston rod 62 is plugged into the inner surface of the socket 21. Specifically, the controller 3 will control the activation of the electric cylinder 61 to make the piston rod 62 drive the card column 63 to move downward. The downward moving card column 63 will be inserted into the inside of the socket 21 and stuck. At this time, the inside of the cab The driver cannot open the car door to avoid the car door colliding with the vehicle behind; a window 11 is provided at the upper end of the car door body 1, and a partition 12 is fixedly connected between the top inner wall and the bottom inner wall of the car window 11, and an audible and visual alarm 4 is installed on the side of the partition 12 close to the interior of the car, and the input end of the audible and visual alarm 4 is electrically connected to the controller 3; specifically, after the door locking mechanism 6 performs the anti-collision operation, the controller 3 will also control the audible and visual alarm 4 to flash and emit a beeping sound to remind the driver of the danger; the cooperation of the above structures can improve the anti-collision ability of the car door body 1.
[0024] Reference Figures 1-4, the input ends of the controller 3, the sound and light alarm 4, the infrared sensor 5 and the electric cylinder 61 are electrically connected to the vehicle power supply; specifically, the vehicle power supply can provide electrical energy for the activation of the controller 3, the sound and light alarm 4, the infrared sensor 5 and the electric cylinder 61; the outer surface of the clamping column 63 is bonded with a rubber pad 64, and a plurality of deformation holes 65 are evenly arranged inside the rubber pad 64. The outer diameter of the rubber pad 64 is smaller than the inner diameter of the insertion hole 21; specifically, when the clamping column 63 is inserted into the insertion hole 21, if the driver does not pay attention to the vehicle coming from behind and forcibly pushes the door body 1 to open outward, the clamping column 63 will limit the door body 1 by abutting against the inner wall of the insertion hole 21 to prevent the door body 1 from opening, and the rubber pad 64 can perform deformation buffering between the outer surface of the clamping column 63 and the inner wall of the insertion hole 21, reducing the pressure when the clamping column 63 abuts against the inner wall of the insertion hole 21, reducing loss, and at the same time, the deformation holes 65 provide deformation space for the deformation of the rubber pad 64.

[0026] In the parking state, the infrared sensor 5 can sense and measure the distance to the surrounding vehicles and feed back the data to the controller 3. If the vehicle coming from behind is close and at a dangerous distance, the controller 3 will control the start of the electric cylinder 61 to make the piston rod 62 drive the clamping column 63 to move downward, and the downward moving clamping column 63 will be inserted into the inside of the socket 21 and stuck. At this time, the driver in the cab cannot open the door to avoid the door colliding with the vehicle coming from behind. At the same time, the controller 3 will also control the sound and light alarm 4 to flash and emit a beeping sound to remind the driver of the danger; the cooperation of the above structures can improve the anti-collision ability of the door body 1.
[0027] On the other hand, when the column 63 is inserted into the socket 21, if the driver forcibly pushes the door body 1 outward to open without paying attention to the vehicle coming from behind, the column 63 will limit the door body 1 by abutting against the inner wall of the socket 21, preventing the door body 1 from opening, and the rubber pad 64 can perform deformation buffering between the outer surface of the column 63 and the inner wall of the socket 21, reducing the pressure when the column 63 abuts against the inner wall of the socket 21 and reducing losses. At the same time, the deformation hole 65 can provide deformation space for the deformation of the rubber pad 64.
