[0002] At present, there are more and more private cars in my country, and parking is difficult and inconvenient, which has become a problem for car owners. The continuous growth of the number of cars in my country, especially in some communities, parking lots, or on the roadside, has made the problem of parking more prominent, leading to random parking, or irregular parking, one car taking up two spaces and occupying public space; or the front and rear cars are parked too close, making it impossible for car owners to get their cars; or often encountering parking spaces that are not large enough to park the car accurately, and it is easy to damage your car when parking. Summary of the invention

[0003] The present invention aims to solve the problem of parking difficulties. When the parking space is not enough for normal parking, the car can be parked accurately in any direction in all directions, making parking intelligent and accurate, thereby improving the safety and convenience of parking and taking out the car, and meeting people's life needs. To this end, the present invention provides an intelligent all-round parking mechanism, which is fixed under the chassis of the car through a fixed bracket seat, and the wheels are lifted off the ground through the operation of a two-stage lifting mechanism, and then the driving mechanism works, and the direction of the car body can be automatically adjusted under the control of the intelligent system, so that the car can be parked in the parking space horizontally or in any direction.

[0004] The technical solution adopted by the present invention to solve the technical problem is: an intelligent all-round parking mechanism, the second lifting mechanism controls the lifting and lowering of the first lifting mechanism, the first lifting mechanism controls the lifting and lowering of the driving mechanism, the driving mechanism can control walking and steering, and two driving wheels are installed on the driving wheel bracket of the driving mechanism, and the driving wheels have built-in motors and star reduction mechanisms, and each driving wheel can move independently.

[0005] The driving wheel bracket is provided with a rotating shaft, which is installed in the lower end bearing of the telescopic tube. The driving wheel bracket can rotate in the bearing of the telescopic tube.

[0006] The first lifting mechanism includes a first lifting nut, a first lifting screw, a first lifting gear, a telescopic small tube, a telescopic middle tube, and a large tube. The driving gear is meshed with the first lifting gear. The first lifting screw is meshed with the first lifting nut installed and fixed in the telescopic small tube. The telescopic small tube is installed in the telescopic middle tube, and the telescopic middle tube is installed in the large tube. The telescopic small tube can slide, extend or contract in the telescopic middle tube.

The second lifting gear nut can mesh with the second lifting screw to move upward or downward, and the rotation of the active gear drives the second lifting gear nut to move.

[0014] Because the second lifting gear nut is installed in the slider bracket, and the slider bracket is connected and fixed to the upper end of the large tube, when the driving motor is working, it drives the active gear, and the active gear drives the mutually meshing second lifting gear nut to mesh and move in the second lifting screw, thereby driving the slider bracket and the large tube installed on the fixed seat bracket to move upward or downward, realizing the second-level lifting movement.

[0015] The fixing bracket can be installed and fixed on the chassis of the vehicle. When the driving motor is working, the intelligent all-round parking mechanism can be realized to lift the whole vehicle off the ground, and then the movement of the driving wheels can be controlled by the intelligent control system to park the vehicle at a required position.
