The inside position that lies in fin 201 both sides of lift ring 301 all is provided with range finding wheel 307, and range finding wheel 307 meshes the transmission with fin 201, and the inside power generation mechanism (not shown in the figure) that is provided with of lift ring 301, power generation mechanism and range finding wheel 307 rope connection, the inside one side at every range finding wheel 307 of lift ring 301 is provided with speed sensor, and power generation mechanism is connected with microcontroller, and speed sensor is connected with microcontroller.
A first magnet is arranged inside the sliding rod 303, a second magnet is arranged at the position, outside the sliding rod 303, of the sliding ring 304 in a sleeved mode, and the sliding rod 303 is communicated with an external air supply system.
After the sliding ring 304 moves upwards or downwards along the damping spring 4, air is introduced into the sliding rod 303, the first magnet adsorbs the second magnet to move, so that the sliding ring 304 moves downwards on the sliding rod 303, the scheduling ball 305 extrudes the damping spring 4, the damping spring between the scheduling ball 305 and the lower connecting plate 1 is contracted, the effective number of turns of the damping spring 4 is reduced, and the rigidity of the damping spring 4 is increased;
when the stiffness of the damper spring 4 needs to be restored, the sliding ring 304 is first driven by the second magnet and the first magnet to slide on the sliding rod 303, the pressing of the scheduling ball 305 on the damper spring 4 is released, and then the rotating disk 302 drives the sliding rod 303 to rotate reversely again, so that the sliding ring 304 moves down or up on the damper spring 4, and the scheduling ball 305 is located at the initial position.
The working principle of the invention is as follows:
the damping device is arranged at a position where an electric vehicle needs to be arranged, and the connecting plate 1 is connected with a vehicle body of the electric vehicle;
when the electric vehicle runs on a smooth road surface, the damping spring 4 provides damping; when the electric vehicle runs on a bumpy road, the compression cylinder 2 is compressed, the pressure inside the compression cylinder 2 changes, and the lifting ring 301 slides outside the compression cylinder 2 under the pushing of the sliding rod 303.
After the sliding ring 304 moves upwards along the damping spring 4, air is introduced into the inside of the sliding rod 303, the first magnet adsorbs the second magnet to move, so that the sliding ring 304 moves downwards on the sliding rod 303, the scheduling ball 305 extrudes the damping spring 4, the damping spring between the scheduling ball 305 and the lower connecting plate 1 contracts, the effective number of turns of the damping spring 4 is reduced, and the rigidity of the damping spring 4 is increased.
When the lifting ring 301 moves up and down, the distance measuring wheel 307 rotates under the driving of the fin 201, the distance measuring wheel 307 provides power for the power generation mechanism, and the rotation speed sensor transmits data to the microcontroller.
When the compression cylinder 2 is compressed, the piston 203 compresses the hydraulic oil, the eardrum 206 is in contact with the hydraulic oil, the eardrum 206 is compressed under the change of the internal pressure of the compression cylinder 2, the eardrum 206 is in a compressed state, the eardrum 206 is sunken towards the inside of the pressure chamber, the internal air pressure of the pressure chamber is increased, and the air on one side of the feedback plate 207 close to the eardrum 206 is compressed to the other side of the feedback plate 207, so that the air pressure on the other side of the feedback plate 207 is increased; the change of the pressure inside the hydraulic cylinder by the air pressure detection circuit is realized through the change of the air pressure at the side, far away from the tympanic membrane 206, of the feedback plate 207; as the air passes through the airflow path, the air presses against the spoiler 212, causing the spoiler 212 to flex, which flexing of the spoiler 212 generates an electrical current.
The pressure detection circuit monitors the frequency of air pressure change, monitoring of the expansion frequency of the compression cylinder 2 is achieved, the work of the rotary disc 302 and the damping cylinder 210 is conveniently controlled by the microcontroller, when the road jolts and the diameter of the damping ring 214 needs to be reduced, namely the rigidity of the compression cylinder 2 needs to be enhanced, every two adjacent inner retraction rods 216 are attracted to each other through a magnetic field, under the action of the magnetic field, the two inner retraction rods 216 slide in the outer retraction sleeve 217, the diameter of the damping ring formed by the inner retraction rods 216 and the outer retraction sleeve 217 is further reduced continuously, and after the set aperture is reached, the diameter of the damping ring 214 is kept unchanged by controlling the size of current in a coil.
When the compression cylinder 2 is stretched, the eardrum 206 is in a stretched state, negative pressure is generated outside the eardrum 206 due to the damping effect of the piston 203 on hydraulic oil generated by the damping cylinder 210, the eardrum 206 is in an outward protruding state, the air pressure inside the pressure chamber is reduced, the air on one side of the feedback plate 207 close to the eardrum 206 becomes thin, the air on the other side of the feedback plate 207 moves to one side of the feedback plate 207 close to the eardrum 206, the flow blocking plate 212 changes the bending direction, the flow blocking plate 212 generates current again, the flow passage of the hydraulic oil is changed by the damping cylinder 210 under the control of the micro-controller, and the backflow damping is increased.
When the compression cylinder 2 is extended, the vehicle is quickly restored to a stable state due to the change of the rigidity of the damper spring 4 and the return damping of the hydraulic oil.
When the diameter of the damping ring 214 needs to be increased, every two adjacent inner telescopic rods 216 repel each other through a magnetic field, and the diameter of the damping ring 214 is continuously increased under the action of the magnetic field.
When the limitation on the rigidity of the damping spring 4 needs to be removed, the sliding ring 304 slides on the sliding rods 303 under the driving of the second magnet and the first magnet, the extrusion of the scheduling ball 305 on the damping spring 4 is removed, then, the rotating disc 302 drives the four sliding rods 303 to rotate, the sliding ring 304 rotates under the driving of the sliding rods 303, the sliding ring 304 drives the scheduling ball 305 to slide on the damping spring 4, the scheduling ball 305 drives the sliding ring 304 to move downwards, the number of circles of the damping spring 4 between the scheduling ball 305 and the connecting plate 1 located below is changed by the sliding of the scheduling ball 305, and therefore the number of effective circles between the scheduling ball 305 and the connecting plate 1 located above is increased.
