Detailed Description

The invention relates to a novel automobile transverse parking system, when an automobile is driven to the right side of a parking space, the automobile can be parked in the parking space in one step by only rotating four wheels by 90 degrees to enable the automobile to transversely move. The system is arranged on an automobile chassis, takes a motor as power, and synchronously drives four wheels to rotate for 90 degrees through a set of mechanical transmission device, so that the transverse movement of the automobile is realized. The whole system is simple in structure and low in cost, is suitable for popularization and application in the fields of electric automobiles and the like, and enables a novice to park safely and quickly for warehousing.

The invention aims to install a novel transverse parking system through an automobile chassis, and drive a mechanical transmission device through a motor to drive four wheels to synchronously rotate for 90 degrees, so that a vehicle can transversely drive into a parking space. See fig. 1.

A novel automobile transverse parking system mainly comprises a motor 1, a pull rod 2 and four cranks 3; the method is characterized in that: motor 1 installs in the round hole that chassis 4 reserved (wherein the motor designs the lectotype according to specific use condition, and the rated power of motor is also different when vehicle size weight is different, does not appoint specific model), and pivot 5 is down, and gear 6 is installed to the end. The pull rod 2 is arranged in a groove at the longitudinal center of the chassis 4, and a gear 6 on the motor 1 is meshed with a rack 7 at the side surface of the pull rod 2. When the motor 1 rotates, the gear 6 drives the rack 7 to move, and the pull rod 2 can move back and forth along the longitudinal direction of the vehicle body. One end of the crank 3 facing the outer side of the vehicle body is directly connected with the wheel 8, the middle part of the crank 3 is in the shape of a circular arc and is assembled in a circular arc groove of the chassis 4, and the center of the circular arc is the center of the wheel. The bosses 9 at the two ends of the pull rod 2 are assembled in the slide rails 10 of the four cranks 3, and when the pull rod 2 moves forwards and backwards, the four cranks 3 can be synchronously driven to rotate around the centers of the wheels 8. The crank 3 attached to the left side of the vehicle body has a slightly different shape from the right side, ensuring that it does not collide with each other during rotation. As shown in fig. 9, the crank is a hollow elongated structure 20 in the portion contacting the pull rod, and in order to avoid the elongated structures of the left and right cranks colliding with each other during movement, the elongated structures of the two cranks are different in height, and the left side is lower and the right side is higher. Like this at the crisscross in-process of motion, like the twolip of scissors, two rectangular structures are crisscross from top to bottom and are passed through, can not bump, and the chassis has reserved the required space of mechanical motion for transmission to it is spacing when the crank rotates to 90 degrees, ensures that the wheel can accurately rotate 90 degrees positions, see fig. 2.

Taking an electric automobile with four wheels provided with hub motors as an example, when the novel transverse parking system is used, firstly, the automobile is driven to the right side of a longitudinal parking space, and the figure is shown in fig. 3 and 4; then, the motor is started to rotate in the positive direction, and the crank is driven by the pull rod to enable the four wheels to rotate 90 degrees synchronously, which is shown in fig. 5 and 6; and finally, starting the vehicle to move forward, starting the motor to rotate reversely after the vehicle transversely enters the parking space, and rotating the wheels back to 0 degree, as shown in fig. 7 and 8. When leaving the parking space, only need the above-mentioned operation of reverse repetition can.

The invention comprehensively applies various mechanical transmission principles. Firstly, a gear-rack transmission principle is applied to enable a motor to rotate to drive a pull rod to do linear motion. And secondly, a pull rod-crank transmission principle is applied, so that the pull rod moves linearly and synchronously drives the four cranks to rotate, and the wheels synchronously rotate by 90 degrees.

The invention specifically designs three research schemes, and the three schemes are sequentially considered in order to rotate the wheel by 90 degrees. The first is to add a completely independent steering system on the chassis of the automobile, such as a jack with wheels at the bottom for steering. The automobile is retracted into the chassis at ordinary times, extends downwards when in use, lifts up the automobile, and puts down the automobile after rotating 90 degrees. However, the steering system has a large volume, and a large force is required to lift the vehicle, so that the realization difficulty is high.

And the second is that a set of steering system is added on each wheel, each wheel can rotate independently, and the rotation of 90 degrees can be realized under the unified control. This steering system is feasible in principle, but has the problems of requiring 4 sets of independent motors and rotating devices, being expensive and consuming much electric energy.

The third scheme is that one motor drives one mechanical transmission system to make four wheels rotate 90 deg synchronously. Because only one motor is used, the cost is greatly saved, and the energy is saved.

As shown in fig. 9, 10 and 11, the steps for manufacturing the lateral parking system according to the present invention are described.

Firstly, designing a mechanical transmission device structure according to the size and the position of an automobile chassis and wheels, and calculating the power of a motor;

secondly, purchasing 1 motor, manufacturing 1 pull rod, 4 cranks and 1 gear, and adopting 3D printing when manufacturing a scaling model, as shown in figure 9;

thirdly, modifying the automobile chassis, reserving the installation positions of a mechanical transmission device and a motor and the space required by mechanical movement on the chassis, and referring to fig. 10;

and fourthly, mounting a gear on a motor rotating shaft, mounting wheels at the tail end of a crank, assembling all parts on the chassis, and finally completing the motion test, which is shown in figure 11.
