Description

Technical Field

[0001] The utility model relates to the field of automobile shock absorption, and more specifically, to a rubber shock absorption component for an automobile. Background Art

[0002] The shock absorbing mechanisms that need to be used in automobiles commonly include shock absorbing rod assemblies and shock absorbing block assemblies. The shock absorbing rod assembly can usually be simplified as an elastic telescopic rod, which is mostly used in suspension systems. The shock absorbing block assembly can usually be simplified as two block-shaped elements that can move towards or away from each other. These two block-shaped elements require bushings to perform a certain degree of restraint and shock absorption, and are mostly used in automobile seats.

[0003] When installing the shock-absorbing bushings for the above two mechanisms, it is necessary to use the corresponding shock-absorbing bushings. Currently, there are few shock-absorbing bushings on the market that are suitable for both mechanisms. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a rubber shock-absorbing assembly for an automobile. The technical problem to be solved by the utility model is that when installing the shock-absorbing bushings, the shock-absorbing rod assembly and the shock-absorbing block assembly need to use their respective corresponding shock-absorbing bushings. Currently, there are few shock-absorbing bushings on the market that are suitable for both mechanisms.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rubber shock-absorbing component for automobiles, comprising a bushing body, one side of the bushing body is vertically elastically slidably connected to a connecting block 2 and the other side is elastically slidably and movably connected to a connecting block 1, a cavity is defined in the bushing body, a plurality of air outlet holes are defined on the side wall of the cavity, two rows of ribs are obliquely and fixedly connected in the cavity, and the two rows of ribs are symmetrically arranged about the bushing body.

[0006] Preferably, rubber balls are fixedly connected between adjacent ribs.

[0007] Preferably, a first reinforcement sleeve and a second reinforcement sleeve are fixedly connected in the bushing body, a corner is provided on the inner side of the bushing body, and the first reinforcement sleeve and the second reinforcement sleeve are respectively located on both sides of the corner.

[0008] Preferably, the connecting block 1 is rotatably connected to the bushing body.

A slot is provided in the bushing body, and a block is elastically rotatably connected to the connecting block 1, and the block and the slot are engaged with each other.

[0009] Preferably, the outer side wall of the bushing body is in a curved arch shape.

[0010] Technical effects and advantages of the utility model:

[0011] 1. The connecting block 1 and the connecting block 2 respectively achieve the purpose of the first shock absorption through the elastic force between them and the bushing body. When the two sections in the telescopic rod are further compressed, the bushing body is compressed, that is, the space volume in the cavity is compressed and discharged through the air outlet. At this time, the deformation of the bushing body can achieve the purpose of the second shock absorption.

[0012] 2. The first shock absorption purpose is achieved through the deformation between the connecting block 1, the connecting block 2 and the bushing body, and the second shock absorption purpose is achieved through the volume change of the cavity. In addition, the arrangement of two rows of ribs can reduce the degree of lateral displacement of the two elements during the relative extrusion process, that is, it achieves the purpose of lateral limitation to a certain extent, while retaining a certain degree of lateral displacement, the shock absorption purpose between the two elements is improved.

[0018] Embodiment 1

[0019] See also Figure 1-3A rubber shock-absorbing assembly for automobiles comprises a bushing body 1, one side of the bushing body 1 is vertically elastically slidably connected with a connecting block 2 9 and the other side is elastically slidably and movably connected with a connecting block 1 2, a cavity 5 is provided in the bushing body 1, a plurality of air outlet holes 6 are provided on the side wall of the cavity 5, two rows of ribs 7 are obliquely and fixedly connected in the cavity 5, and the two rows of ribs 7 are symmetrically arranged about the bushing body 1. When in use, the shock-absorbing assembly can be applied to a shock-absorbing rod mechanism or a shock-absorbing block mechanism. First, take the shock-absorbing rod assembly as an example. The shock-absorbing rod is mostly an elastic telescopic rod. Therefore, one section of the telescopic rod is inserted into the connecting block 2 9 and the other section is inserted into the connecting block 1 2. The connecting block 1 2 and the connecting block 2 9 are both transitionally matched with a corresponding section of the telescopic rod, so that it is relatively simple for the user to install or disassemble the shock-absorbing assembly. When the two sections of the telescopic rod in the shock-absorbing rod assembly move relative to each other, the connecting block 1 2 and the connecting block 2 9 respectively play a first role through the elastic force between them and the bushing body 1. For the purpose of secondary shock absorption, when the two sections in the telescopic rod are further compressed, the bushing body 1 is compressed, that is, the volume of the space in the cavity 5 is compressed and discharged through the air outlet 6. At this time, the deformation of the bushing body 1 can achieve the purpose of secondary shock absorption. When the two sections in the telescopic rod move away from each other and the telescopic rod is reset as a whole, the bushing body 1 is deformed to enlarge the space in the cavity 5, and the gas rushes into the cavity 5 under the action of pressure, thereby quickly expanding the volume in the cavity 5, so that the bushing body 1 can quickly recover. In addition, the connecting block 1 2 and the connecting block 2 9 are also reset under the action of their corresponding elastic forces. Take the shock-absorbing block mechanism as an example. The shock-absorbing block mechanism includes two non-contacting elements, but a bushing is usually required between the two elements for limiting and shock-absorbing. At this time, the connecting block 2 is connected to one of the elements by a detachable connection method such as bolts and nuts, and then the connecting block 2 9 is connected to the other element. After that, if the two elements move relative to each other, the first shock-absorbing purpose is achieved through the deformation between the connecting block 2, the connecting block 2 9 and the bushing body 1, and the second shock-absorbing purpose is achieved through the volume change of the cavity 5. In addition, the arrangement of two rows of ribs 7 can reduce the degree of lateral displacement of the two elements during the relative extrusion process, that is, it achieves the purpose of lateral limitation to a certain extent, while retaining a certain degree of lateral displacement while improving the shock-absorbing purpose between the two elements. In summary, the design can be applied to a variety of shock-absorbing occasions, which improves the practicality of use.

[0020] Embodiment 2

[0021] See also Figure 1-3 On the basis of the above embodiment, rubber balls 8 are fixedly connected between adjacent ribs 7. The rubber balls 8 can not only absorb vibrations through their own elastic deformation in the vertical direction, but also reduce the degree of lateral displacement of the upper and lower ends of the bushing body 1 through cooperation with the ribs 7, that is, they can achieve the purpose of shock absorption and position limiting in the lateral direction.

[0022] The bushing body 1 is fixedly connected with a reinforcing sleeve 1 3 and a reinforcing sleeve 2 4. A corner is formed on the inner side of the bushing body 1. The reinforcing sleeve 1 3 and the reinforcing sleeve 2 4 are respectively on both sides of the corner. When the telescopic rod is compressed, the bushing body 1 is deformed, and the reinforcing sleeve 1 3 and the reinforcing sleeve 2 4 are deformed along with the bushing body 1. The bushing body 1 is compressed along the direction of the corner edge. At this time, the clamping force of the connecting block 1 2 and the connecting block 2 9 on the two ends of the telescopic rod can be removed, and the clamping force of the reinforcing sleeve 1 3 and the reinforcing sleeve 2 4 on the two ends of the telescopic rod can also be used to assist the telescopic rod in shock reduction.

[0023] The connecting block 2 is rotatably connected to the bushing body 1. The connecting block 2 can rotate relative to the bushing body 1 and can also move elastically in the vertical direction. A card slot 11 is provided in the bushing body 1. A card block 10 is elastically rotatably connected to the connecting block 2. The card block 10 and the card slot 11 are engaged with each other. When in use, the two sections of the partial telescopic rod will rotate to a certain extent while telescoping. At this time, the connecting block 2 9 is connected to one section of the telescopic rod, and the connecting block 2 is connected to the other section of the telescopic rod. If the connecting block 2 9 and the connecting block 2 rotate, that is, the bushing body 1 and the connecting block 2 rotate, the card block 10 on the connecting block 2 will engage when passing through the card slot 11 on the bushing body 1. This engagement can assist in limiting the rotation angle between the two sections of the telescopic rod, thereby reducing the circumferential friction between the two ends of the telescopic rod.

[0024] The outer side wall of the bushing body 1 is in a curved arch shape, which can increase the degree of compression of the bushing body 1 and the rebound rate after the cavity 5 absorbs gas.
