[0002] With the rapid development of the automobile industry, the demand for rapid maintenance and repair has increased year by year. Traditional rescue service vehicles have gradually revealed their disadvantages. In the context of this market demand, it is imperative to increase the functions of rescue service vehicles. Traditional rescue vehicles are mostly truck-type, with various maintenance tools or auxiliary equipment placed in the car. In some cases, a lifting mechanism is needed to lift the vehicle being repaired. Most traditional lifting mechanisms have complex structures and large volumes. They are placed in the car and must be pulled out of the car and lowered to the ground by manpower when used. The lifting device is heavy and very inconvenient to move. It not only consumes a lot of manpower and material resources, but also prolongs the entire operation process and wastes time. Therefore, a method or device that can solve the above problems is now needed. Summary of the invention

[0009] Figure 2 It is a partial enlarged view of the blocking frame part in the embodiment of the present invention (the blocking frame is in a recovered state). DETAILED DESCRIPTION

[0010] The specific implementation of the present invention will be described below with reference to the accompanying drawings. Figure 1 , Figure 2As shown: A driving mechanism for a rescue vehicle power lifting vehicle, comprising a swing bracket 1 arranged in the rescue vehicle compartment, one end of the swing bracket 1 being hinged to the rear of the rescue vehicle compartment through a rotating shaft, a swing cylinder 2 being arranged in the rescue vehicle compartment, the cylinder barrel of the swing cylinder 2 being hinged to the bottom plate of the rescue vehicle compartment, and the end of the working shaft of the swing cylinder 2 being hinged to the middle part of the swing bracket 1, when the swing bracket 1 is in a horizontal state, the central axis of the swing cylinder 2 forms an angle of 8-10 degrees with the horizontal plane, and the swing A telescopic oil cylinder 3 is respectively provided on both sides of the bracket 1, and the telescopic oil cylinder 3 is connected to a telescopic frame 4 slidably connected to the swing bracket 1. A motor 5 is provided at one end of the telescopic frame 4 facing the front of the rescue vehicle, and the working shaft of the motor 5 is connected to a driving sprocket 6. A passive sprocket 7 is also rotatably supported at one end of the telescopic frame 4 facing the rear of the rescue vehicle. A driving chain 8 is wound around the driving sprocket 6 and the passive sprocket 7. A connecting hanger 9 is provided on the driving chain 8, and the connecting hanger 9 matches with a hook provided at the front end of the power lift vehicle.

[0011] The telescopic frame 4 is provided with two symmetrically distributed blocking frames 10 at one end facing the rear of the rescue vehicle, and the blocking frames 10 are rotationally connected to the telescopic frame 4. A driving member 11 is provided at the rear of the blocking frame 10, and the driving member 11 consists of a first part 12 and a second part 13 that are interconnected and smoothly transitioned, wherein the first part 12 is parallel to the blocking frame 10, and the second part 13 forms an obtuse angle with the first part 12, and a toggle cylinder 14 that matches the position of the second part 13 is provided on the swing bracket 1.

[0012] The working process of the driving mechanism for the power lift vehicle of the rescue vehicle of the embodiment of the present invention is as follows: in the initial state, the hook on the power lift vehicle (not shown in the figure) is hooked on the connecting hanger 9, and the connecting hanger 9 is located at one end close to the front direction of the rescue vehicle. At this time, the power lift vehicle is supported by the telescopic frame 4 as a whole and recovered in the compartment of the rescue vehicle;

[0013] When a motor vehicle is in danger, the rescue personnel drive the rescue vehicle to the vicinity of the faulty vehicle, open the rear door of the vehicle, and control the swing cylinder 2 to work through the control system. The swing cylinder 2 extends, drives the swing bracket 1 to swing to a certain inclination angle and then stops. Then, the telescopic cylinder 3 is controlled to work through the control system to drive the telescopic frame 4 downward. During the downward movement of the telescopic frame 4, the driving member 11 on the rear end blocking frame 10 collides with the toggle cylinder 14 during the movement. Specifically, the second part 13 on the driving member 11 collides with the toggle cylinder 14, and the toggle driving member 11 rotates, thereby driving the blocking frame 10 from a state perpendicular to the axis of the telescopic frame 4 to a state parallel to the axis of the telescopic frame 4.

[0014] Then the control system will control the motor 5 to work, drive the driving sprocket 6 to rotate, and then lower the power lift connected to the connecting hanger 9 from the telescopic frame 4 through the driving chain 8. The power lift is finally smoothly lowered to the ground after being guided by the blocking frame 10, and the connecting hanger 9 is removed, and the power lift is separated from the device;

[0015] After the work of the power lift is completed, when it needs to be recovered into the compartment of the rescue vehicle, the connecting hanger 9 is hung on the hook at the end of the power lift again, the motor 5 is started, and the active sprocket 6 drives the connecting hanger 9 to move toward the inside of the compartment, and the power lift will be pulled back to the telescopic frame 4, and then the telescopic cylinder 3 will work to drive the telescopic frame 4 upward, and finally the swing cylinder 2 will be recovered, and the telescopic frame 4 will be restored to a horizontal state. Finally, the operator manually rotates the two blocking frames 10 back to the initial position and closes the compartment door.
