Description
Technical Field
The invention is suitable for the field of automobile safety, and particularly relates to an automobile overturn preventing device which is used for preventing an automobile from inclining or overturning due to too small turning radius or too high turning speed.
Background
When the turning radius of an automobile, particularly a racing automobile, is too small or the turning speed is too high, wheels and the road surface are kept relatively static in the normal direction during turning, and the gravity center of the automobile body still has a centrifugal tendency, so that centrifugal force is generated during over-turning, the automobile body tends to turn outwards around the length direction, the suspension stress on the outer side of a curve is larger, and the automobile body inclines towards the outer side, so that the automobile topples or turns over.
In order to prevent the automobile from overturning or turning over, the current widely adopted forms mainly comprise two types: one is a rear wheel follow-up steering system, which has the advantages of improving the stability of the vehicle, improving the maneuverability and reducing the turning radius, thereby making up the driving danger caused by over-steering of the vehicle, and simultaneously, enabling the vehicle to be more flexible when driving at low speed and more stable when turning at high speed for medium and large-sized vehicles and luxury vehicles. The disadvantage of rear wheel steering is obviously that one more set of steering is required, i.e. more mechanical parts are required, but many vehicle enterprises do not have subsequent products, which means that when the mechanical parts are damaged, the original parts are not easily found in the after-market. The other is that a stressed cross bar is additionally arranged outside the vehicle body, and a supporting force is given when the vehicle body overturns to an angle, so that the vehicle body is prevented from overturning at a larger angle. The device in the form of the novel vehicle body structure undoubtedly increases the width of the vehicle body, influences normal traffic order and brings harm to other vehicles or pedestrians.
Disclosure of Invention
The invention aims to provide an anti-overturn device for an automobile, which adopts the following technical scheme:
2 guide rods with the axial direction consistent with the width direction of the vehicle are fixedly arranged on the vehicle chassis near the gravity center position of the whole vehicle, 1 screw rod with the axial direction consistent with the width direction of the vehicle is rotatably arranged in the middle of each guide rod, and one end of each screw rod is fixedly connected with an output shaft of a stepping motor fixedly arranged on the vehicle chassis; 2 unthreaded holes and 1 screw are seted up on the counter weight slider, the position that corresponds 2 guide arms and 1 screw rod, 2 unthreaded holes respectively with 2 guide arms sliding fit, 1 screw and 1 screw spiro union cooperation.
The steering mechanism further comprises a control module, wherein an angle sensor is mounted on a steering shaft of the vehicle steering gear, the angle sensor is connected with the control module, the control module is connected with the stepping motor, and the control module controls the forward rotation, the overturning and the rotating number of turns of the stepping motor according to a rotating signal transmitted by the angle sensor.
Furthermore, when the steering shaft of the vehicle steering gear is at the angle position of 0 degree, the control module does not send instructions to the stepping motor, and the counterweight sliding block is positioned between the 2 guide rods and the 1 screw rod; when the steering shaft rotates anticlockwise, the control module sends a reverse rotation instruction to the stepping motor to enable the counterweight sliding block to move towards the left sides of the 2 guide rods and the 1 screw rod; when the steering shaft rotates clockwise, the control module sends a forward rotation instruction to the stepping motor to enable the counterweight sliding block to move towards the right sides of the 2 guide rods and the 1 screw rod.
Further, when the steering shaft rotates anticlockwise or clockwise by more than 90 degrees, the control module controls the stepping motor to finally drive the counterweight sliding block to move to the leftmost side or the rightmost side of the 2 guide rods and the 1 screw rod.
The control module is used for controlling the forward rotation or the reverse rotation of the stepping motor and the number of turns of rotation of the stepping motor according to signals transmitted by the 2 signal lines.
Further, when a left turn light of the vehicle flickers, the control module sends a reverse rotation instruction to the stepping motor to enable the counterweight sliding block to move towards the left sides of the 2 guide rods and the 1 screw rod; when a right steering lamp of the vehicle flickers, the control module sends a forward rotation instruction to the stepping motor to enable the counterweight sliding block to move towards the right sides of the 2 guide rods and the 1 screw rod.
Further, when the left turn light of the vehicle flickers for more than 2 seconds, the control module controls the stepping motor to finally drive the counterweight sliding block to move to the leftmost side of the 2 guide rods and the 1 screw rod; when the right turn light of the vehicle flickers for more than 2 seconds, the control module controls the stepping motor to finally drive the counterweight sliding block to move to the rightmost side of the 2 guide rods and the 1 screw rod.
Compared with the prior art, the invention changes the gravity center position of the automobile through the left-right displacement of the counterweight sliding block, and can effectively solve the problem that the automobile body inclines or overturns due to the undersize turning radius or the over-high speed of the automobile.

Detailed Description
In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described with reference to the accompanying drawings.
In another preferred embodiment, when the steering shaft rotates counterclockwise or clockwise by more than 90 °, the control module controls the stepping motor 3 to finally drive the counterweight sliding block 4 to displace to the leftmost side or the rightmost side of the 2 guide rods 1 and the 1 screw rod 2.
The popular way is that the automobile turns sharply in which direction, and the counterweight sliding block moves to which side of the automobile body. Along with the movement of the counterweight sliding block towards the turning direction, the gravity center position of the automobile body also moves towards the corresponding direction, so that the weight of the automobile body on the side is increased, and the automobile body is pressed, so that the torque of the automobile body caused by sharp turning, namely the trend that the automobile body overturns outwards around the length direction, can be counteracted, and the side tire is prevented from lifting off the ground to cause the side inclination and even overturn of the automobile body.
When the turning is finished and the steering shaft is at the position of recovering 0 degree, the control module sends an instruction of reverse turning to the stepping motor 3 to enable the counterweight sliding block 4 to return to the middle initial position of the 2 guide rods 1 and the 1 screw rod 2.
In another preferred embodiment, when the left turn light of the vehicle flickers for more than 2 seconds, the control module controls the stepping motor 3 to finally drive the counterweight sliding block 4 to move to the leftmost side of the 2 guide rods 1 and the 1 screw rod 2; when the right turn light of the vehicle flickers for more than 2 seconds, the control module controls the stepping motor 3 to finally drive the counterweight sliding block 4 to move to the rightmost side of the 2 guide rods 1 and the 1 screw rods 2.
The principle is similar to that of embodiment 1 and will not be described again.
The invention is not described in detail, but is known to the state of the art or common general knowledge.
