The fixed seats of the damping shaft 31 and the movable seat are connected through a connecting shaft. The end of the connecting shaft located inside the movable seat is provided with a spring washer, a limiting washer, an oil storage washer and a nut. The damping effect is achieved by the friction between the spring washer, the limiting washer and the oil storage washer and the movable seat. When the movable seat rotates, the damping force is generated by friction to slow down the rotation speed of the movable seat.

The one-piece structure is provided with a folding mechanism 3, which is connected by four connecting frames 32. The four connecting frames 32 allow the two sides of the vehicle to be flipped downward by 90 degrees to reach the retracted state. The retracted state can be locked by the damping shaft 31, and the unfolded state can be formed into a whole by its own gravity, which is convenient for transportation and movement of the vehicle.

[0025] The working principle of the foldable portable rail emergency vehicle provided by the present invention is as follows: when the rail emergency vehicle is in use, the base 33 is deflected outward by ninety degrees, so that the two bases 33 are parallel to the shell 1, and the support plate 34 is also parallel to the shell 1. The shell 1, the base 33 and the support plate 34 form an integral body to form a vehicle frame. In this process, as the base 33 rotates, the connecting frame 32 also rotates synchronously. The side of the connecting frame 32 below the limit groove 2 fits with the top wall of the limit groove 2, and at the same time forms a supporting and connecting effect for the shell 1 and the base 33, preventing the base 33 from deflecting upward. At the same time, the upper ends of the base 33 and the support plate 34 fit with the corresponding surfaces of the shell 1, further preventing the base 33 from deflecting upward, so that the shell 1, the base 33 and the support plate 34 form a whole, and always maintain a straight state by their own gravity. Then the unfolded vehicle is moved to the track, the external battery is placed in the battery slot 8 and connected to the vehicle, and the deflection is When the user sits on the seat 35, the motor 38 is controlled by the single chip microcomputer 9, and the output shaft of the motor 38 drives the driving wheel 39 to rotate, and the moving wheel 37 also rotates accordingly, and the emergency vehicle starts to move to realize the transportation of personnel. When not in use, the two bases 33 are deflected downward by 90 degrees so that the base 33 and the shell 1 are perpendicular to each other. The damping shaft 31 generates a damping force through friction to keep the base 33 stable. The entire emergency vehicle is in a folded state, and the volume becomes smaller, which is convenient for the transportation and movement of the vehicle.

[0026] It is worth noting that the microcontroller 9 disclosed in the above embodiment is an STM8S003F3P6 microcontroller, the motor 38 is an SGM7G-09A7C61 motor, the damping shaft 31 is a YZ8398-001 damping shaft, and the microcontroller 9 controls the motor 38 and the lighting lamp 4 using methods commonly used in the prior art.
