Compared with the traditional shock absorbing technology, the shock absorbing mechanism of the invention is installed between the chassis and the vehicle body, and the body can overcome the influence of the unevenness of the ground on the vehicle body under the action of the shock absorbing mechanism; the traditional shock absorbing mechanism can be used at a certain impact strength. The next guarantee is flexible to mitigate the impact on the ground. When the vehicle speed is fast or the ground protrusion is large and the impact is large, the shock absorbing mechanism exceeds the range of the impact force that can be relieved by itself, and the shock absorbing mechanism has an inelastic stroke, which causes the vehicle body to collide with the chassis; When it is long, the shock absorbing mechanism will lose some elasticity and cause the collision between the body and the chassis. In the present invention, the bottom plate of the damper mechanism is connected to the chassis, the first top plate is connected to the vehicle body, and the damper mechanism is arranged between the first top plate and the bottom plate, and the damper inner rod in the damper mechanism can be accompanied by a certain resistance sliding in the damper sleeve. The accompanying resistance makes the impact quickly damped; the outer periphery of the damping structure has a pneumatic spring that can adjust the air pressure. The height of the air pressure can affect the elastic coefficient of the pneumatic spring; the pneumatic spring introduces high-pressure air through the first air inlet and passes through the first The air port slowly releases high-pressure air. The higher the air pressure in the pneumatic spring, the faster the air is released from the first air outlet; the piston ring in the pneumatic spring slides in the annular cylinder, and the piston ring slides to compress the gas in the annular cylinder. The compressed gas generates a repulsive force. The gas pressure affects the compressibility of the gas, which in turn affects the elastic coefficient of the pneumatic spring. In addition, the pneumatic spring has a conventional rigid spring. When the impact is within the elastic spring elastic receiving range, the pneumatic spring The internal air pressure is stable, when the impact exceeds the elastic spring elastic tolerance range, The trigger will activate the pneumatic switch through the lower top block support and the lower top block triggering mechanism. When the pneumatic switch is opened, the high pressure gas will be introduced into the pneumatic spring through the first air inlet, so that the elastic coefficient of the pneumatic spring is increased to alleviate the next excessive Shock. The specific embodiment is as follows: initially, the body body under its own weight, the damping mechanism and the pneumatic spring in the damping mechanism maintain a certain relative position, and at this time, the length of the damping mechanism is the longest, and the contact surface of the lower top block and the trigger block is triggered. In the plane, the second spring is compressed to a certain extent; when the local surface protrusion is small, the amplitude of the lower top block swings up and down is small, and the contact surface of the lower top block and the trigger block is a trigger plane when the upper and lower amplitude swings slightly; the trigger block passes through the vertical The vertical plate slides in the vertical movement guide groove to move up and down, and the downward movement of the lower top block moves downward with the trigger block while compressing 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 block. During the whole small-scale operation, the trigger mechanism does not trigger, and the gas switch is always in the closed state. When the rigid spring can not withstand the impact, the body will have a rigid impact with the chassis. When the shock absorbing mechanism is in the shortest state, the triggering vertical rod is pressed by the lower top block to the card slot to cooperate with the card block, and the block passes through the third telescopic rod and the third Shrink sleeve Sliding and snapping into the card slot, the card block arc and the card slot bevel are designed to facilitate the card block to enter the card slot; when the impact is temporarily lost, the rigid spring and the pneumatic spring act. The lower top block starts to move upwards, but at this time, the trigger block cannot move up and down because the card block is stuck in the card slot; the trigger horizontal plate, the trigger vertical bar and the trigger block can slide laterally along the traverse guide groove, and the lower top block rises. After a small amplitude, the contact surface of the lower top block and the trigger block changes from the trigger plane to the trigger ramp. During the process, the trigger block moves under the action of the third spring, triggering the transverse plate to move toward the pneumatic switch installation position, and triggering through the slide during the movement. The switch adjusting block allows the high-pressure gas in the high-pressure gas tank to enter the pneumatic spring, increasing the elasticity of the pneumatic spring and preventing the impact caused by the next large impact. Afterwards, the lateral movement of the trigger block causes the card block to gradually disengage from the card slot. When the card block is disengaged from the card slot, the card slot, the triggering vertical rod and the trigger block will move upward under the action of the second spring and contact with the lower top block. The lower top block first contacts the trigger ramp to cause the trigger cross-plate to return to the original position of the gas switch direction until the lower side of the lower top block contacts the trigger plane, and finally closes the gas switch. If the road surface is relatively flat, the high-pressure gas in the pneumatic spring will slowly release to the pressure recognized by the original air outlet through the first air outlet, and restore the normal elastic coefficient. The design of the skateboard is to oscillate up and down in the whole process of triggering the horizontal plate. The design of the skateboard ensures that the switch adjustment block can be triggered at any position up and down. 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 both designed to increase lateral stability when the spring is compressed. In the present invention, only when the current top block is raised by a small amount, the gas enters the pneumatic spring. The design purpose is that the increase of the length of the shock absorbing mechanism after the rise of a small section reduces the resistance of the high pressure gas cylinder gas when entering the pneumatic spring; The purpose of the one-way inlet is that the pressure of the pneumatic spring does not apply pressure through the first air inlet, and can only be applied through the first air outlet.
