Description

Technical Field

[0001] The utility model relates to the field of vehicle shock absorbers, in particular to an intelligent active electromagnetic induction shock absorber. Background Art

[0002] At present, pneumatic and hydraulic adjustable damping vehicle shock absorbers have been widely used in various types of vehicles. When a vehicle encounters potholes or stones during driving, the vehicle shock absorber can effectively reduce and absorb the vibrations transmitted by the road surface, buffer the impact between the shock-absorbing spring and the vehicle body, improve comfort and reduce noise. It also reduces the tire noise generated between the tire and the ground. When the tire is jolted by a rough road surface, it can reduce the direct impact force on the vehicle. However, in the actual application process, it is found that traditional pneumatic and hydraulic active suspensions are too complex, and the reliability has not been solved. In summary, noise is easily generated when driving on complex road conditions, the riding comfort is poor, the effect of the buffer shock-absorbing spring is poor, and it is easily damaged. Therefore, the existing adjustable damping shock absorbers need to be further improved and optimized. For this reason, we propose an intelligent active electromagnetic induction shock absorber. Content of the Utility Model

[0003] The main purpose of the utility model is to provide an intelligent active electromagnetic induction shock absorber. The intelligent active electromagnetic induction system has become the fastest-response active suspension system in the world at present. The damping of its shock absorber can change steplessly with the strength of the magnetic field, and a millisecond-level control reaction speed can be achieved. The electronic controller can continuously monitor 1000 times within one second, and the action reaction is faster than the design of traditional hydraulic or pneumatic valves. Even on the most rugged road surface, it can provide the corresponding damping force of the shock absorber, increase the contact between the tire and the ground, reduce the tire rebound, control the transfer of the vehicle's center of gravity and the degree of pitching forward and backward, so as to maintain the stability of the vehicle. The electronic controller can analyze the data of the acceleration sensor in real time, provide the corresponding current to the solenoid valve, and when the current increases, the damping force of the shock absorber increases, that is, it feels "harder". On the contrary, when the current weakens, the shock absorber becomes "softer", calmly coping with the tests of bad road conditions and potential dangers, ensuring the stability of the vehicle body and being in full control. Under the integration of the electronic controller, while providing excellent safety performance, it allows the vehicle owner to enjoy more driving pleasures.

[0004] To achieve the above object, the technical solution adopted by the present utility model is as follows: an intelligent active electromagnetic induction shock absorber, including an oil storage cylinder mechanism, inside which a working cylinder is provided.

A guiding mechanism is arranged between the upper ends of the oil storage cylinder mechanism and the working cylinder. A piston mechanism is arranged between the working cylinder and the piston rod mechanism. A bottom valve mechanism is arranged between the inner surfaces of the bottom ends of the oil storage cylinder mechanism and the working cylinder. An electromagnetic valve is arranged between the middle and lower parts of the outer wall of the oil storage cylinder mechanism and the middle and lower parts of the oil guiding mechanism.

[0018] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0019] Such as Figures 1-4As shown in the figure, the intelligent active electromagnetic induction shock absorber includes an oil storage cylinder mechanism 5, and is characterized in that: a working cylinder 3 is arranged inside the oil storage cylinder mechanism 5; an oil guiding mechanism 10 is arranged on the outer surface of the working cylinder 3; a piston mechanism 4 is arranged at the tail of the piston rod mechanism 1; a combination of the piston rod mechanism 1 and the piston mechanism 4 is arranged inside the working cylinder 3; a guide mechanism 2 is arranged between the upper end of the oil storage cylinder mechanism 5 and the upper end of the working cylinder 3; a piston mechanism 4 is arranged between the working cylinder 3 and the piston rod mechanism 1; a bottom valve mechanism 7 is arranged between the inner surface of the bottom end of the oil storage cylinder mechanism 5 and the inner surface of the bottom end of the working cylinder 3; a solenoid valve 11 is arranged between the middle and lower parts of the outer wall of the oil storage cylinder mechanism 5 and the middle and lower parts of the oil guiding mechanism 10; an acceleration sensor 6 is arranged at the middle and lower parts of the outer wall of the oil storage cylinder mechanism 5; corresponding connection terminals of the solenoid valve 11 and the acceleration sensor 6 are provided with corresponding connection terminals of a wire harness 9; and corresponding connection terminals of an electronic controller 8 are provided with corresponding connection terminals of the wire harness 9.

[0020] Further, the combination of the piston mechanism 4 arranged at the tail of the piston rod mechanism 1 is movably connected to the inner surface of the working cylinder 3 through the inner through hole of the guide mechanism 2, and the oil guiding mechanism 10 arranged on the outer surface of the working cylinder 3 is detachably connected. By adopting such an oil guiding mechanism 10, the internal space can be saved, the impact toughness and stability of the shock absorber can be improved during use, abnormal noises can be eliminated during driving on complex road conditions, and it is durable and not easily damaged.

[0022] Further, the solenoid valve 11 is detachably connected between the middle and lower parts of the outer wall of the oil storage cylinder mechanism 5 and the middle and lower parts of the oil guiding mechanism 10. After the above steps are assembled, the required shock absorber oil is injected according to the drawing requirements, and then the upper end of the oil storage cylinder mechanism 5 is spin-formed and flanged so that all the components inside the oil storage cylinder mechanism 5 become integrally non-detachable.

The electronic controller can analyze the data of the acceleration sensor in real time and provide the corresponding current to the solenoid valve. When the current increases, the damping force of the shock absorber increases, that is, it feels "harder"; conversely, when the current weakens, the shock absorber becomes "softer", calmly coping with the tests of harsh road conditions and potential dangers, ensuring the vehicle body is stable and under control.
