Technical Field

[0001] This utility model belongs to the technical field of automotive seat shock absorption components, and relates to a shock absorption component for automotive seats. Background Technology

[0002] With the rapid development of my country's automotive industry, consumers are demanding higher and higher levels of comfort in their vehicles. As the component that has the most direct contact with drivers and passengers, the comfort of car seats is increasingly valued by consumers, making it a crucial factor in the automotive design process.

[0003] Since the car seat is an integral part of the vehicle structure, it vibrates when the car body vibrates. Excessive vibration amplitude can affect not only passenger comfort but also potentially driving. However, current research on automotive vibration primarily focuses on wheels, axles, and the chassis, with little attention paid to car seats. Yet, as the part in direct contact with the driver, the seat's vibration damping performance has the most direct and significant impact on the driver. Therefore, designing a vibration damping component for car seats to address these issues is essential. Summary of the Invention

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The following is in conjunction with the appendix Figure 1-3 The specific embodiments of this utility model will be described in further detail.

[0021] In this embodiment, through Figures 1-3As shown, this utility model includes a mounting frame 1, with annular fixing frames 2 fixed at both the left and right ends of the mounting frame 1. Damping components are snapped onto both annular fixing frames 2, and counterweight columns 3 are inserted into both damping components. A counterweight block 4 is fixed between the two counterweight columns 3.

[0022] The shock absorber is installed on the vehicle using mounting bracket 1. When the vehicle vibrates, it will cause mounting bracket 1 to vibrate, which in turn causes the damping component, counterweight column 3 and counterweight block 4 to vibrate. The vibration of counterweight block 4 and counterweight column 3 compresses the damping component, which absorbs and slows down the vibration, thereby achieving the effect of noise reduction and vibration damping.

[0023] In this embodiment, the length of the counterweight 4 is the same as the distance between the two rubber cylinders 11 on the side closest to the counterweight 4;

[0024] This prevents counterweight 4 from moving left or right.

[0025] In this embodiment, the damping assembly includes a damping ring 6, a placement ring 7, and a limiting ring 5, which are sequentially located away from the center of the counterweight 4. The limiting ring 5 is fixed together with the placement ring 7 through the damping ring 6, and the limiting ring 5, the damping ring 6, and the placement ring 7 are arranged concentrically.

[0026] In this embodiment, through Figure 2-3 As shown, the width of the placement ring 7 is the same as the thickness of the annular fixing frame 2. A positioning block 8 is fixed on the placement ring 7. A positioning groove 9 is provided on the inner ring wall of the annular fixing frame 2 to engage with the positioning block 8. The annular fixing frame 2 is sleeved on the placement ring 7.

[0027] In this embodiment, the diameters of both the limiting ring 5 and the damping ring 6 are larger than the inner diameter of the annular fixing frame 2;

[0028] The limiting ring 5, damping ring 6, and placement ring 7 are all made of rubber. By squeezing the limiting ring 5, the limiting ring 5 passes through the annular fixing frame 2, so that the annular fixing frame 2 is fitted onto the placement ring 7. The limiting ring 5 and damping ring 6 limit the annular fixing frame 2 in the left and right directions. The rotation of the placement ring 7 is restricted by the cooperation of the positioning block 8 and the positioning groove 9.

[0029] In this embodiment, the counterweight 4, counterweight column 3, and rubber cylinder 11 are concentrically arranged, while the counterweight 4 is eccentrically arranged with respect to the limiting ring 5. The rubber cylinder 11 is eccentrically arranged with respect to the limiting ring 5 (see figure). Figure 3 );

[0030] The eccentric setting causes the counterweight 4 and the rubber cylinder 11 to produce uneven stress distribution when they impact the inner rings of the limiting ring 5 and the damping ring 6. This unevenness helps to better absorb vibration energy, thereby improving the shock absorption effect.

[0031] In this embodiment, a rubber sleeve 11 is fixed to the inner wall of the damping ring 6 by a conical sleeve 10;

[0032] Fixing the rubber cylinder 11 with the conical sleeve 10 can reduce the contact area with the rubber cylinder 11, reduce the space occupied by the inner ring of the limiting ring 5, and give the counterweight column 3 and the rubber cylinder 11 room to move.

[0033] In this embodiment, the inlet diameter of the rubber cylinder 11 on the side closer to the counterweight 4 is smaller than the diameter of the counterweight column 3, and the outlet diameter of the rubber cylinder 11 on the side farther from the counterweight 4 is larger than the diameter of the counterweight column 3. A reinforcing rib 12 is fixed on the outer ring of the rubber cylinder 11 on the side closer to the counterweight 4, and a reinforcing block 13 is fixed on the outer ring of the rubber cylinder 11 on the side farther from the counterweight 4.

[0034] Reinforcing blocks 1 are equidistantly distributed around the circumference of rubber cylinder 11;

[0035] The reinforcing rib 12, reinforcing block 13, rubber cylinder 11, and conical sleeve 10 are all made of rubber.

[0036] The inlet diameter of the rubber cylinder 11 is smaller than that of the counterweight 4, so that when the counterweight column 3 is inserted, the rubber cylinder 11 is stretched open, thus wrapping the counterweight column 3 more tightly.

[0037] The reinforcing rib 12 can improve the strength of the rubber cylinder 11, and the reinforcing block 13 is a stress point that can improve the strength of the rear end of the rubber cylinder 11.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
