Generally, the car can only move forward or backward. To move the rear part (rear wheel) of the vehicle to the left or to the right for a certain distance, it can only be achieved by forward and backward, and the front or rear of the vehicle must have sufficient forward and backward. The distance, including on both sides of the front of the car, also needs to have sufficient lateral width. The longer the body of the vehicle, the greater the required distance in all directions. With the continuous increase of vehicles, parking difficulties have become very common and obvious, especially in prosperous cities and road sections, as well as in commercial and trade cities, company courtyards, and residential courtyards with chaotic traffic. It is very difficult to find a parking space, and it is difficult to move. It is also very difficult to drive the vehicle out.

Detailed ways

In Figure 1, the upper end of the left telescopic rod 2 is fixed on the frame structure 1 on the left side of the bottom of the vehicle through the hinge of the shaft sleeve and the shaft pin. The axis of the shaft pin is parallel to the ground, and the axis of the shaft pin is perpendicular to the wheel. Axis; the upper end of the right telescopic rod 3 is also fixed on the frame structure 1 on the right side of the bottom of the vehicle through the hinge of the shaft sleeve and the shaft pin. The axis of the shaft pin is parallel to the ground, and the axis of the shaft pin is perpendicular to the wheel axis. There is a certain axial distance between the upper end of the left telescopic rod 2 and the upper end of the right telescopic rod 3; the lower ends of the left telescopic rod 2 and the right telescopic rod 3 are fixed together on the bearing plate 4 through the hinge of the shaft sleeve and the shaft pin , the axis of the axle pin on the bearing plate 4 is parallel to the ground, the axis of the axle pin is perpendicular to the axis of the wheel, the left telescopic rod 2 and the right telescopic rod 3 are V-shaped on the bearing plate 4.

When the left telescopic rod 2 and the right telescopic rod 3 are extended at the same distance at the same time, the load-bearing plate 4 touches the ground and is located in the middle position between the left and right wheels of the vehicle. When the left and right telescopic rods continue to extend, the vehicle will be lifted ), the weight on the left and right wheels will be transferred to the load-bearing plate 4 through the left and right telescopic rods. At this time, if the left telescopic rod 2 continues to extend and the right telescopic rod 3 does not move, the entire vehicle will be supported to the left. Next The right telescopic rod 3 is first shortened (retracted), and the wheel also falls on the left side, completing a process of lateral movement. It can be seen that a process can only move the vehicle to a certain side for a certain distance, If the distance of side movement is not enough, it is necessary to lift the load-bearing plate 4 again and place it in a position biased towards the moving direction, so as to obtain a larger moving distance in one process, and control the telescopic stroke and telescopic time of the left and right telescopic rods respectively. , the direction and distance of lateral movement of the vehicle can be controlled, thereby realizing the function of lateral movement of the vehicle.

In FIG. 2 , when the left telescopic rod 2 and the right telescopic rod 3 are shortened (retracted) at the same time, the load-bearing plate 4 is lifted up to a certain distance from the ground, so as to facilitate the normal running of the vehicle.

In order to facilitate operation and control, there are travel sensors on the left and right telescopic rods, and the program controller is used to control the action. The action distance and action sequence of the left and right telescopic rods, including the lateral movement direction of the vehicle, can be controlled by a predetermined program. The direction and distance of the lateral movement can be temporarily and simply determined by the operator and then completed by the program controller. Since the load-bearing plate 4 has to bear the weight of the rear of the vehicle, its landing area and mechanical strength should be determined according to different models. If it is a truck, especially a heavy-duty semi-trailer, the landing area and thickness of the load-bearing plate 4 should be increased accordingly. thick. The left telescopic rod 2 and the right telescopic rod 3 can be hydraulic telescopic rods, screw (spiral) telescopic rods, or rack-type telescopic rods. Due to the weight of the body that needs to be supported and the type of the vehicle, the general small vehicle is not equipped with a hydraulic system, and an electric screw telescopic rod is used, or an electric rack telescopic rod is used. If the vehicle itself is equipped with hydraulic equipment, hydraulic telescopic rod. There are also many telescopic elements of various stereotypes in the electromechanical industry, which can be selected according to needs.

Due to the different chassis structures of various vehicles, the locations and conditions for easy installation of the vehicle lateral movement device are also different, including the size of the installation space and the mechanical strength of the installation site, etc., so here the vehicle chassis is installed on the vehicle lateral movement device. The parts are collectively referred to as frame structure 1. If the vehicle lateral movement device is installed on the girder of the vehicle chassis, then the telescopic stroke of the left and right telescopic rods needs to be larger, and the total length will be longer, because the girder of the vehicle is supported. When starting, the wheel does not leave the ground due to the shock-absorbing spring or shock-absorbing steel plate of the rear wheel, so the ideal installation position of the lateral movement device of the vehicle is to be installed on the axle structure of the vehicle, such as on the differential gear. The axle housing, for vehicles without a differential at the rear of the vehicle, is mounted on a structure that is rigidly connected to the axle. For vehicles with additional vehicle lateral movement devices installed in the later stage, whether it is installed on the beam of the vehicle or on the axle structure, there are no ready-made components to use, so it is necessary to add some additional components according to the specific conditions of various vehicles. The structural parts are used to install the lateral moving device of the vehicle. These structural parts play the role of fixing the parts, strengthening the structure, dispersing the pressure and extending the position. On the frame or on the structure of the axle.

In FIG. 3 , for some light vehicles, and for some vehicles with a large space in the chassis, the lateral movement function of the vehicle may be realized by means of a rotating strut. On the central position of the frame structure 1 at the bottom of the vehicle, a rotary power 5 is installed, the output shaft of the rotary power 5 is parallel to the ground and perpendicular to the axis of the rear wheel of the vehicle, and the rotary power 5 can rotate clockwise or counterclockwise; On the output shaft of the rotating power 5, a rotating strut 6 is fixedly installed, and the rotating strut 6 is installed on the output shaft of the rotating power 5 like the propeller of an airplane, and rotates synchronously, and the rotating strut 6 is perpendicular to the output of the rotating power 5. The shaft and the rotating strut 6 have a certain radial length. During the rotation of the rotating strut 6, the outer end of the rotating strut 6 will intermittently touch the ground and support and move the vehicle. At the position of the radial end of the rotating strut 6, an arc-shaped (shoe-shaped) ground contact structure is provided to increase the ground contact area of the rotating strut. The rotation track of the radial end of the rotating strut 6 is circle, as shown by the circle dotted line in Figure 3. When the rotating strut 6 rotates counterclockwise, the end of the rotating strut 6 contacts the ground from the left position of the vehicle, and supports the left wheel first, and then moves the entire vehicle to the left. When the rotating strut 6 is clockwise When rotating, the end of the rotating strut 6 contacts the ground from the right position of the vehicle, and firstly supports the right wheel, and then moves the entire vehicle to the right, so as to realize the function of lateral movement of the vehicle. The method of using the rotating strut to realize the function of lateral movement of the vehicle has the advantages of simple structure and convenient operation. Only by controlling the forward or reverse rotation of the rotating power 5, the rear of the vehicle can be moved to the left or right. side movement. When the rotating strut 6 stops working, it should stop at a position parallel to the ground to avoid the end of the rotating strut 6 touching the road surface. A travel positioning switch can be set to limit the stop position of the rotating power 5 .

The rotational power 5 mentioned in this technical solution refers to the rotational power driven by a motor, with corresponding rotational speed and torque, and with corresponding mechanical strength. It can be a gear reducer driven by an electric motor, a turbine reducer, etc., It may also be rotational power driven by a hydraulic motor.

In Figure 4, considering the limited space in the upper chassis of some vehicles, the end of the large-diameter rotating strut may touch the upper or surrounding functional parts of the chassis under working conditions, such as fuel tanks, spare tires, exhaust pipes Therefore, it is not suitable to use the large-diameter rotating strut shown in Figure 3.

When the eccentric shaft on the crank arm 7 rotates to the bottom dead center, it will touch the ground through the link-type stay 8 and support the rear of the vehicle. Under normal circumstances, under the action of its own weight, the link-type strut 8 is always vertically sleeved on the eccentric shaft of the crank arm 7 and moves relative to the eccentric shaft of the crank arm 7 in a vertical posture. The radial length of the crank arm 7 plus the length of the connecting rod-type strut 8 should be greater than the distance between the output shaft of the rotary power 5 and the ground. The circular dotted line in FIG. 4 is the running track of the eccentric shaft of the crank arm 7 . When the rotary power 5 rotates counterclockwise, the crank arm 7 drives the link-type strut 8 to be lowered from the left position of the vehicle and contact the ground. 8 Keep vertical and support the crank arm 7 to support the left wheel of the vehicle first, and then move the entire vehicle to the left; when the rotary power 5 rotates clockwise, the crank arm 7 drives the link-type strut 8 from the right position of the vehicle. Put down and touch the ground, the link-type strut 8 remains vertical and supports the crank arm 7 to support the right wheel of the vehicle first, and then move the entire vehicle to the right, so as to realize the function of lateral movement of the vehicle. The lateral movement of the vehicle is realized by rotating the crank strut, which has the advantage of reducing the size requirements for the surrounding space and is easy to operate. It is only necessary to control the forward or reverse rotation of the rotating power 5 to realize the left side of the rear of the vehicle. or move to the right. When the crank arm 7 stops working, it should stop in the upward position, and lift the connecting rod-type strut 8 to a high position to avoid the contact floor of the connecting-rod-type strut 8 from touching the road surface. A travel positioning switch can be set to limit the fixed rotation. The stop position of the power 5.
