Description

Technical Field

[0001] This invention relates to the field of shock absorption technology for motor vehicles, specifically applicable to shock absorption of seats and the whole vehicle in all motor vehicles, including but not limited to automobiles, tricycles, two-wheeled vehicles, electric wheelchairs, airplanes and other types of manned mobile devices, and can be extended to special fields such as spacecraft and high-altitude recovery capsules in the future. Background Technology

[0002] Traditional shock absorption systems rely heavily on springs and dampers for passive cushioning, resulting in a "hard-on-hard" force transmission that fails to counteract vibration transmission at its source. This limited cushioning effect leads to insufficient ride comfort and safety. This invention aims to provide a novel shock absorption solution with a simple structure and smooth vibration reduction. Through a reverse dynamic compensation mechanism, it weakens vibration transmission at its source, overcoming the shortcomings of existing technologies. Summary of the Invention

[0003] This invention discloses a reverse dynamic compensation damping system, which dynamically offsets external impacts through reverse motion to achieve efficient damping. Attached Figure Description Figure 1 This is a schematic diagram illustrating the structural principle of the seat shock absorption system of the present invention. The components corresponding to the various reference numerals in the figure are as follows: (1) Seat, which can also be replaced with any part that needs shock absorption; (2) Return spring; (3) Pulley connecting the vehicle body, or a pulley fixed to the vehicle body; (4) Pulley connecting the axle, or a pulley fixed to the axle; (5) Steel cable, a thin steel wire connecting the seat anchor points; (6) Anchor point fixing the vehicle body. Explanation: This figure clearly shows the core components and connection relationships of the system: The seat (1) is connected to the vehicle body through the return spring (2), and at the same time, the steel cable (5) passes through the pulley (3) connecting the vehicle body and the pulley (4) connecting the axle in sequence, and is finally fixed to the anchor point (6) fixing the vehicle body. The principle is to adjust the rise and fall of the seat by changing the length of the steel cable through the misalignment of the pulleys (3) and (4) during bumps to complete the shock absorption structure. The description strictly corresponds to the reference numerals in the figure, and there are no new unmarked features.

[0004] (I) Core Structure This system includes: Upper load-bearing structure (1): Depending on the application scenario, it can be selected as a seat or upper vehicle body = passenger space; When used for seat shock absorption, the upper load-bearing body (1) is the seat; When used for vehicle shock absorption, the upper load-bearing body (1) is the upper vehicle body including the seat.

[0005] Return spring (2): connected to the upper support body (1), used to smoothly reset the upper support body after the impact ends; Guide pulley (3): Fixed to the vehicle body / fuselage, providing guidance for the flexible transmission cable; Drive pulley (4): connected to the chassis, axle or landing gear, and moves synchronously with the lower load-bearing end; Flexible transmission cable (5): It passes through the guide pulley (3) and the drive pulley (4) in sequence, with one end connected to the upper load-bearing body (1) and the other end fixed to the fixed anchor point (6) of the vehicle body. Fixed anchor point (6): Used to fix the end of the flexible transmission steel cable (5) to ensure the stability of the cable tension.

[0006] In this invention, all pulleys are fixed pulleys, wherein the guide pulley (3) is fixed to the vehicle body, and the drive pulley (4) is fixed to the axle and moves synchronously with the axle to change the shape of the steel cable.

[0007] When a vehicle encounters road bumps, vibrations during travel, or impacts from an aircraft landing: The lower bearing end (chassis / axle / landing gear) drives the drive pulley (4) to move upward, and generates relative displacement with the guide pulley (3), which increases the bending of the steel cable (5) and shortens its effective length, causing the seat (2) to move downward; The steel cable (5) pulls the upper load-bearing body (1) downward, which forms a reverse dynamic cancellation with the upward impact, greatly reducing the transmission of vibration to the human body or the upper vehicle body; After the impact ends, the lower bearing end falls back to its original position, the tension of the steel cable (5) decreases, and the upper bearing body (1) is smoothly reset under the action of the return spring (2), maintaining overall horizontal stability; By adjusting the lateral distance and number of guide pulleys (3) and drive pulleys (4), the up and down stroke of the upper support (1) can be precisely controlled, and the amplitude of the bump can be adjusted in a controllable manner.

[0008] (III) Layout and Extended Applications Seat (1) Independent shock absorption: The independent control arrangement of one wheel corresponding to one seat is adopted. Each seat is controlled and buffered separately by the corresponding wheel below, with less mutual interference and more accurate shock absorption response. It is suitable for various passenger vehicle seat scenarios.

[0009] Overall vehicle shock absorption: When the chassis / lower part is heavy and the upper body is light, the upper body is pulled downward by the downward compression of the lower part of the vehicle when the wheels bounce, so that the whole vehicle can achieve a softer overall cushioning and improve driving stability.

[0010] Adaptive adjustment: This structure can adaptively adjust the compensation intensity according to the impact amplitude. The greater the impact, the stronger the reverse buffer. By adjusting the distance between each drive pulley (4) and the distance between each guide pulley (3), the operating amplitude of the seat (1) can be adjusted, thereby reducing the impact of vibration on the human body and vehicle body from the source and adapting to different road conditions and impact scenarios.

[0011] IV. Beneficial Effects Excellent cushioning effect: It uses reverse motion to offset the impact, and the cushioning effect is significantly better than traditional passive shock absorption schemes, which can effectively reduce the transmission of bumps and instantaneous impacts.

[0012] Wide range of applications: It can cover all sports vehicle seats and vehicle shock absorption, with strong versatility and rich application scenarios. In the future, it can be extended to special fields such as spacecraft and high-altitude recovery.

[0013] Precise and stable control: Supports independent control of each wheel and seat, with each seat's shock absorption not interfering with each other, resulting in precise response and better ride stability.

[0014] Flexible and adaptable: It can achieve seat shock absorption or whole vehicle shock absorption, and can be flexibly adapted to different models and scenario requirements by adjusting the pulley parameters.

[0015] Enhanced safety and comfort: It effectively cushions against driving bumps, instantaneous impacts, and aircraft landing impacts, significantly improving ride comfort and safety.

[0016] Low implementation cost: Simple structure, low cost, stable and reliable, easy to industrialize, and has broad promotion value.
