Background technique

At present, the side parking device of the prior art is mainly to install four or more hydraulic lifting columns under the chassis of the car, and through the lifting movement between the hydraulic lifting columns, the car is separated from the ground to move forward or backward or to the left. Or the moving action to the right provides a kind of solution that the car gets out of trouble by arranging the hydraulic lifting mechanism.

Such as Chinese patent CN207594929U discloses automobile escape, side parking and lifting device, a hydraulic lifting mechanism composed of a plurality of hydraulic lifting columns and a base plate is installed at the lower part of the chassis of the vehicle, one end of the hydraulic lifting column is connected to the base plate, and the other end is connected to the chassis of the vehicle , the retracted hydraulic lifting column is embedded in the chassis of the car, and the expanded hydraulic lifting column supports the car to move away from the ground.

This technology is an existing relatively advanced device, but it still has the following disadvantages:

1. If you need to install this device, you must change the frame structure of the car chassis, change the safety of the whole vehicle, and install at least four devices, which are just at the load point of the whole vehicle. It is very easy to change the large frame structure during use, endangering the driving safety of the whole vehicle;

2. During the high-speed driving of the vehicle, the device installed on the chassis of the vehicle will change the airflow route of the chassis of the vehicle and may fall. If this happens, it will bring great safety hazards;

3. When the car has a sinkhole, it usually occurs on the soft muddy, sandy and other roads of the roadbed. The contact point between the device and the ground is small, and it cannot really get out of trouble. When the device can be used to get out of trouble, The hydraulic device moves the whole vehicle off the ground. At this time, the wheels are off the ground, and it is impossible to really escape, and there is a danger of rollover;

4. The electric device is used to drive the hydraulic device to go up and down. Under the idling condition, the load on the circuit and the engine is increased. The chassis is easy to bump and encounter water, which may easily cause leakage or deformation of the hydraulic rod.

Contents of the invention
