Technical Field
[0001] This utility model relates to the technical field of damping and shock absorption devices, and in particular to a multi-stage damping composite shock absorption device. Background Technology
[0002] To rapidly dampen vibrations between the chassis and body, improving ride smoothness and comfort, shock absorbers are typically installed in automotive suspension systems. Shock absorbers are wear-prone components during vehicle use; their performance directly impacts ride stability and the lifespan of other parts.
[0003] Most current shock absorbers are equipped with a single spring. Some shock absorbers are designed with a two-stage damping structure, but the structure is relatively simple, resulting in poor damping effect and making it difficult to apply to mechanical structures with large vibration forces.
[0004] Therefore, those skilled in the art have provided a multi-stage damping composite shock absorption device to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-stage damping composite shock absorber. When encountering significant vibration, the first damping rod provides primary buffering. When the bottom of the pressure plate contacts the rubber gasket, it pushes the first buffer plate downward, providing secondary buffering through two tower-shaped springs. When the bottom of the first buffer plate contacts the second buffer plate, it pushes the second buffer plate downward, and the first and second connecting plates simultaneously push the two movable plates to move in opposite directions, providing tertiary buffering through two second damping rods. Compared to existing shock absorbers, this design adds a buffering structure, making it suitable for mechanical structures with strong vibrations.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A multi-stage damping composite shock absorber includes a shock absorber frame. Support plates are integrally formed on both sides of the top of the shock absorber frame. Tower-shaped springs are installed inside each of the two support plates. A first buffer plate is installed at the top of each of the two tower-shaped springs. A first damping rod is installed at the top of the first buffer plate. A pressure plate is installed at the output end of the first damping rod. Second damping rods are installed on both sides of the middle of the top of the shock absorber frame. Movable plates are installed at the output ends of the two second damping rods. A first connecting plate and a second connecting plate are rotatably connected to one end of each of the two movable plates. A rotating seat is rotatably connected to one end of each of the first and second connecting plates. A second buffer plate is fixedly installed at the top of the rotating seat.
[0008] Through the above technical solution, when encountering large vibration forces, the design of the first damping rod can provide primary buffering. When the bottom of the pressure plate contacts the rubber gasket, it pushes the first buffer plate to move downward, and the two tower-shaped springs provide secondary buffering. When the bottom of the first buffer plate contacts the second buffer plate, it pushes the second buffer plate to move downward. The action of the first and second connecting plates synchronously pushes the two movable plates to move in opposite directions, and the two second damping rods provide tertiary buffering. Compared with existing shock absorbers, the above structural design adds a buffering structure to the shock absorber, making it suitable for mechanical structures with strong vibration forces.
[0009] Furthermore, positioning rods are integrally provided on both sides of the top of the second buffer plate, and positioning holes are provided at both ends of the middle part of the first buffer plate, with the positioning rods on the same side slidably inserted into the positioning holes.
[0010] With the above technical solution, positioning rods are integrally provided on both sides of the top of the second buffer plate, and positioning holes are provided at both ends of the middle part of the first buffer plate. The positioning rods on the same side are slidably inserted into the positioning holes, so as to facilitate the alignment and connection of the first buffer plate and the second buffer plate.
[0011] Furthermore, the top center of the shock absorber is provided with mounting slots on both sides, and the two second damping rods are respectively installed inside the two mounting slots. The outer ends of the two second damping rods are each fitted with a second spring, and the two ends of each second spring are respectively fixedly connected to the movable plate and the mounting slot on the same side.
[0012] With the above technical solution, mounting slots are provided on both sides of the top center of the shock absorber frame to facilitate the installation of two second damping rods inside the two mounting slots respectively. The outer ends of the two second damping rods are fitted with second springs, and the two ends of each second spring are fixedly connected to the movable plate and the mounting slot on the same side respectively, so as to facilitate the auxiliary second damping rods to perform shock absorption and buffering.
[0013] Furthermore, both of the support plates have a fixing groove inside, and the two tower-shaped springs are respectively installed at the bottom of the two fixing grooves;
[0014] The above technical solution involves creating fixing slots inside both support plates to install tower-shaped springs.
[0015] Furthermore, a first spring is sleeved on the outer end of the first damping rod, and the two ends of the first spring are fixedly connected to the pressure plate and the first buffer plate, respectively.
[0016] Through the above technical solution, a first spring is sleeved on the outer end of the first damping rod, and the two ends of the first spring are fixedly connected to the pressure plate and the first buffer plate respectively, so as to assist the first damping rod in shock absorption and buffering.
[0017] Furthermore, a rubber washer is installed on the top of the first damping rod;
[0018] With the above technical solution, a rubber washer is installed on the top of the first damping rod to support the pressure plate and to prevent the output end of the damping rod from being pressed to the bottom.
[0019] This utility model has the following beneficial effects:
[0020] 1. The multi-stage damping composite shock absorber proposed in this utility model can provide primary buffering when encountering large vibration forces through the design of the first damping rod. When the bottom of the pressure plate contacts the rubber gasket, it pushes the first buffer plate to move downward, and the two tower-shaped springs provide secondary buffering.

Compared with existing shock absorbers, the above structural design adds a buffering structure to the shock absorber, making it suitable for mechanical structures with strong vibration forces.
