Compared with the traditional shock absorbing technology, the shock absorbing mechanism in the present invention is installed between the chassis and the vehicle body, and the vehicle body can overcome the impact of the unevenness of the ground on the vehicle body under the action of the shock absorbing mechanism; The bottom is guaranteed to be elastic to cushion the impact of the ground. When the speed of the vehicle is fast or the ground bump is large and the impact is large, the shock absorbing mechanism exceeds the range of impact that it can relieve, and the shock absorbing mechanism has an inelastic stroke, resulting in collision between the body and the chassis; in addition, when the vehicle is running for a long time For a long time, the shock absorbing mechanism will also lose a certain degree of elasticity and cause the collision between the vehicle body and the chassis. In the present invention, the bottom plate of the damping mechanism is connected to the chassis, the first top plate is connected to the vehicle body, and there is a damping mechanism between the first top plate and the bottom plate. In the damping mechanism, the damping inner rod can slide with a certain resistance in the damping rod sleeve. The accompanying resistance makes the impact quickly damped and stopped; the outside of the damping structure has a pneumatic spring that can adjust the air pressure, and the level of air pressure can affect the elastic coefficient of the pneumatic spring; The air port slowly releases high-pressure air. The higher the air pressure in the pneumatic spring, the faster the air will be released from the first air outlet; the piston ring in the pneumatic spring slides in the annular cylinder, and the sliding piston ring can compress the gas in the annular cylinder , the compressed gas produces a repulsive force, and the air pressure of the gas affects the compressibility of the gas, which in turn affects the elastic coefficient of the pneumatic spring; in addition, there are traditional rigid springs around the pneumatic spring. When the impact is within the elastic tolerance range of the rigid spring, the pneumatic spring The internal air pressure is stable. When the impact exceeds the elastic tolerance range of the rigid spring, the impact will be supported by the lower top block, and the lower top block will trigger the trigger mechanism to open the pneumatic switch. When the pneumatic switch is turned on, high-pressure gas will be introduced into the pneumatic spring through the first air inlet. In the middle, the elastic coefficient of the pneumatic spring is increased to relieve the next excessive impact. The specific implementation method is as follows: at first, under the weight of the vehicle body, the damping mechanism and the pneumatic spring in the shock absorbing mechanism maintain a certain relative position, and at this time the length of the shock absorbing mechanism is the longest, and the contact surface between the lower top block and the trigger block is the trigger. plane, the second spring is compressed to a certain extent; when the ground bulge is small, the lower top block swings up and down in a small range, and the contact surface between the lower top block and the trigger block is the trigger plane when the lower top block swings up and down in a small range; the trigger block passes through the vertical The vertical moving plate slides in the vertical moving guide groove and moves up and down, the downward movement of the lower top block will bring the trigger block down, and at the same time compress the second spring; when the lower top block rises, the trigger block is under the action of the second spring It can follow the rise of the lower top block. During the whole small range of operation, the trigger mechanism does not trigger, and the gas switch is always in the closed state; when the rigid spring cannot withstand the impact due to strong impact, the body will have a rigid impact with the chassis. , the shock absorbing mechanism is in the shortest state, the trigger vertical bar is pressed by the lower top block to the card notch to cooperate with the card block, and the card block is inserted into the card notch through the sliding of the third telescopic rod and the third telescopic sleeve, and the card block The arc of the card block and the slope of the card slot are designed so that the card block can enter the card slot more conveniently; when the impact disappears temporarily after the impact, the lower top block starts to move upward under the action of the rigid spring and pneumatic spring, but at this time The trigger block cannot move up and down because the block blocks the card slot; the trigger horizontal plate, trigger vertical bar and trigger block can slide horizontally along the traversing guide groove. After the lower top block rises by a small range, the lower top block and the trigger block The contact surface changes from the trigger plane to the trigger slope. During the process, the trigger block is under the action of the third spring, and the trigger horizontal plate moves toward the installation position of the pneumatic switch. During the movement, the switch adjustment block is triggered by the slide plate, so that the high-pressure gas tank The high-pressure gas enters the pneumatic spring to increase the elasticity of the pneumatic spring and prevent the impact caused by the next big impact. Later, the lateral movement of the trigger block will cause the block to gradually break away from the slot. When the block is separated from the slot, the slot, the trigger vertical bar and the trigger block will move upward under the action of the second spring and contact the lower top block. The lower top block first contacts with the trigger slope so that the trigger horizontal plate faces away from the direction of the gas switch and restores its original position until the lower side of the lower top block contacts the trigger plane, and finally closes the gas switch. If the road behind is relatively flat, after a period of time, the high-pressure gas in the pneumatic spring will be slowly released through the first air outlet to the pressure recognized by the original air outlet, and the normal elastic coefficient will be restored. The design function of the slide plate is to trigger the horizontal plate to swing up and down throughout the whole process, and the design of the slide plate ensures that any position of the swing up and down can trigger the switch adjustment block. The first telescopic rod and the first telescopic sleeve, the second telescopic rod and the second telescopic sleeve, and the third telescopic rod and the third telescopic sleeve are all designed to increase the lateral stability of the spring when it is compressed. The purpose of the design of the present invention is that the gas will enter the pneumatic spring only after the lower top block rises by a small range, and the length of the damping mechanism increases after a short rise to reduce the resistance when the gas in the high-pressure gas tank enters the pneumatic spring; The design purpose of the one-way inlet is that the pressure applied by the pneumatic spring will not be applied through the first air inlet, but only through the first air outlet.
