CN-122008987-A - Reverse dynamic compensation type damping system

Abstract

The invention discloses a reverse dynamic compensation type damping system, and belongs to the technical field of damping of moving vehicles. The system comprises an upper supporting body, a return spring, a guide pulley, a driving pulley, a flexible transmission steel rope and a fixed anchor point. When the carrier encounters jolt or impact, the lower driving pulley moves upwards, the upper supporting body is pulled by the steel rope to displace downwards, and reverse dynamic compensation is formed with the impact direction, so that the vibration is counteracted. The upper supporting body can be a seat or an upper car body according to application scenes, the system can realize single-wheel single-seat independent damping or whole car integral damping, and the up-down stroke can be controlled by adjusting the distance and the number of the pulleys. The invention has simple structure, low cost and remarkable damping effect, is suitable for various manned mobile equipment such as automobiles, electric vehicles, airplanes, rail transit, airship return cabins and the like, and greatly improves riding comfort and safety.

Description

Reverse dynamic compensation type damping system Technical Field The invention relates to the technical field of vibration absorption of a motion carrier, in particular to vibration absorption of seats of all motion carriers and a whole vehicle, which comprises various manned mobile equipment such as an automobile, a tricycle, a two-wheel vehicle, an electric wheelchair, an airplane and the like, and can be expanded to the special fields of spaceship, high-altitude recovery cabins and the like in the future. Background Traditional shock attenuation relies on spring, attenuator to carry out passive buffering more, belongs to "hard to bump hard" type atress transmission, can't offset the vibrations conduction from the root, and is limited to jolting, impact's buffering effect, leads to taking travelling comfort and security not enough. The invention aims to provide a novel damping scheme with simple structure and stable damping, and the shock transmission is weakened from the root through a reverse dynamic compensation mechanism, so that the defects of the prior art are overcome. Disclosure of Invention The invention discloses a reverse dynamic compensation type damping system which dynamically counteracts external impact through reverse movement to realize efficient damping. Drawings FIG. 1 is a schematic view of the structural principle of the seat cushion system of the present invention. The parts corresponding to the reference numerals in the figure are (1) a seat, which can also be replaced by a part needing damping, (2) a return spring, (3) a pulley connected with the vehicle body, which can also be a pulley fixed on the vehicle body, (4) a pulley connected with an axle, which can also be a pulley fixed on the axle, (5) a steel cable, which is connected with a thin steel wire between seat anchor points, and (6) an anchor point for fixing the vehicle body. The key composition and the connection relation of the system are clearly shown in the description, wherein the seat (1) is connected with a vehicle body through the return spring (2), and simultaneously, the seat sequentially bypasses a pulley (3) connected with the vehicle body and a pulley (4) connected with an axle through the steel cable (5), and is finally fixed at an anchor point (6) for fixing the vehicle body. The descriptions correspond strictly to the reference numerals without newly added unlabeled features. Core structure The system comprises: an upper carrier (1) which can be selected as a seat or an upper vehicle body = manned space according to the application scene; when the upper bearing body (1) is used for seat shock absorption, the upper bearing body is a seat; When the upper supporting body (1) is used for damping the whole vehicle, the upper vehicle body comprises a seat. The return spring (2) is connected with the upper supporting body (1) and is used for enabling the upper supporting body to reset stably after the impact is finished; A guide pulley (3) fixed on the car body/the car body for guiding the flexible transmission steel rope; The driving pulley (4) is connected with the chassis, the axle or the landing gear and synchronously moves along with the lower bearing end; a flexible transmission steel cable (5) which sequentially winds around the guide pulley (3) and the driving pulley (4), one end of the flexible transmission steel cable is connected with the upper supporting body (1), and the other end of the flexible transmission steel cable is fixed at a fixed anchor point (6) of the vehicle body; the fixed anchor point (6) is used for fixing the tail end of the flexible transmission steel cable (5) and ensuring the tension stability of the steel cable. All pulleys in the invention are fixed pulleys, wherein a guide pulley (3) is fixed on a vehicle body, and a driving pulley (4) is fixed on an axle and synchronously moves along with the axle, so as to change the shape of a steel rope. When the vehicle encounters road bumps, driving shocks or aircraft landing shocks: the lower bearing end (chassis/axle/landing gear) drives the driving pulley (4) to move upwards and generate relative displacement with the guide pulley (3), so that the bending of the steel cable (5) is increased, the effective length is shortened, and the seat (2) moves downwards; The steel cable (5) pulls the upper supporting body (1) to displace downwards, and forms reverse dynamic counteraction with upward impact, so that the transmission of vibration to a human body or an upper vehicle body is greatly weakened; After the impact is finished, the lower bearing end falls back and resets, the tension of the steel cable (5) is reduced, the upper bearing body (1) resets steadily under the action of the return spring (2), and the whole level is kept stable; The upper and lower strokes of the upper supporting body (1) can be accurately controlled by adjusting the transverse distance between the guide pulleys (3) and the driving pulleys (4) and the number of the
