As shown in Figures 1 to 3, the present invention provides a vehicle escape device, comprising a hydraulic cylinder 8, a pull rod 3 whose one end is pinned to the free end of a piston rod 2 of the hydraulic cylinder 8, and a tie rod 3 rotatably connected to the hydraulic cylinder 8. A support lever 6 at the other end of the pull rod 3 is rotatably connected to the lift shaft 11 , and a support bracket 4 for lifting the vehicle is provided on the free end of the support lever 6 . The tie rod 3 and the support lever 6 are arranged in pairs, and are symmetrically arranged on the left and right sides of the hydraulic cylinder 8 respectively. A cross rod 13 is fixed on the free end of the piston rod 2 of the hydraulic cylinder 8. It is perpendicular to the piston rod 2 , and the transverse rod 13 is axially symmetrical with respect to the piston rod 2 . Here, the transverse rod 13 forms a pin connection between the tie rod 3 and the piston rod 2 . One end of the two pull rods 3 is respectively connected with the two ends of the cross bar 13 in a one-to-one correspondence, the other ends of the two pull rods 3 are respectively connected with one end of the two support levers 6 in a one-to-one correspondence, and the free ends of the two support levers 6 are connected at the same time. onto the support bracket 4. The hydraulic cylinder 8 is mounted on a mounting plate 9, the mounting plate 9 is further provided with a support frame 12, and the lift shaft 11 is arranged on the support frame 12.

In this embodiment, the support bracket 4 is preferably, but not limited to, fixedly positioned on the free end of the support lever 6 through the ratchet structure 5 . The support lever 6 includes a first rod body and a second rod body. One end of the first rod body is rotatably connected to the pull rod 3, and the other end is connected to one end of the second rod body. The free end of the second rod body is connected by a ratchet wheel. The structure 5 is connected to the positioning support bracket 4, the lifting shaft 11 is set at the connection point of the first rod body and the second rod body, and the second rod body and the second rod body are integrally formed, and the two are sandwiched between them. The angle is greater than 90 degrees. The length of the second rod body is greater than the length of the first rod body.

The hydraulic cylinder 8 in the vehicle escape device is preferably an electric hydraulic cylinder, which provides a power source for the device. When the vehicle needs to be lifted and escaped, the device is placed under the vehicle, so that the hydraulic cylinder 8 does work and drives the piston rod 2 to extend. Therefore, the pull rod 3 is pulled to the left, forcing the support lever 6 to rotate around the lift shaft 11, the support lever 6 rotates clockwise, and the second rod body of the support lever 6 raises the height of the support bracket 4, so that the support bracket 4 is connected to the vehicle. The bottom contacts and lifts the vehicle, and finally completes the lifting operation of the vehicle. Due to the lever principle and the frictional force generated by the contact between the support bracket 4 and the vehicle bottom, the vehicle also completes the translational movement during the lifting process, and finally the pressure is released to smoothly put the vehicle down. , that is, the whole process of getting out of the car is completed.

Since the lifting motion of the vehicle is accompanied by a large translational motion, doing a large translational motion before the completion of the lifting may cause the wheels to interfere with the section of the trapped vehicle during the lifting process, resulting in the failure to successfully complete the lifting motion, and also It is easy to shake and affect the safety of use. Therefore, the present invention proposes a preferred solution of this embodiment. As shown in Figures 1 to 3, the vehicle escape device further includes a base plate, and the base plate is provided with a sliding rail 10, and the sliding rail 10 runs along the The piston rod 2 is arranged in the longitudinal direction, and the mounting plate 9 is slidably fitted on the slide rail 10 . The base plate is also provided with a positioning rod 13 for positioning the base board on the ground. The positioning rod 13 includes a positioning portion 101 and an extension rod 102. The positioning portion 101 is positioned on the ground. The part 101 is fixedly connected, and the other end is rotatably connected to the base plate through the rotating shaft 14 . The extension rod 102 is also slidably fitted with a retractable support rod 7 , the other end of the retractable support rod 7 is rotatably connected to the lift shaft 11 , and the retractable support rod 7 is provided with a buckle for clamping and positioning with the extension rod 102 . The positioning rod 13 increases the contact surface between the base plate and the ground, and enhances the stability.

When the vehicle escape device is lifted, it will be subjected to forces in two directions, namely the vertical downward force generated by the weight of the vehicle, and the friction force generated by the contact between the support bracket 4 and the bottom of the vehicle. Due to the effect of friction, the support bracket 4 and the vehicle chassis are always kept relatively static. At this time, due to the effect of the force, the mounting plate 9 slides to the left on the slide rail 10, which enables the vehicle to perform a stable and smooth lifting motion . After completing the lifting operation of the vehicle, as long as the vehicle is pushed forward, the mounting plate 9 slides to the right on the slide rail 10 to complete the translational movement of the vehicle. Finally, the pressure is relieved and the vehicle is put down smoothly, which completes the whole process of getting out of trouble. .
