Description

Technical Field

[0001] The utility model belongs to the field of automobiles, and particularly relates to a height-adjustable bracket and sliding column assembly and a shock absorber. Background Art

[0002] Automobile shock absorbers are important functional parts that affect the stability, comfort and safety of automobile driving. In order to make the shock absorbers have higher strength, durability and sealing, welding methods are usually used to ensure this.

[0003] Although this welding method has a faster construction speed, it has various defects in terms of safety and quality. On the one hand, the high temperature during the welding process may cause safety accidents such as fire, explosion, burns and acute poisoning.

[0004] Therefore, Chinese patent CN214392194U, entitled "A Riveted Bracket for Automobile Shock Absorber", discloses a technical solution that replaces the traditional electric welding process with a riveting process, thereby avoiding the safety problems and environmental pollution problems that may be caused by the electric welding process, ensuring the personal safety of construction workers and achieving the purpose of environmental protection.

[0005] However, it is obvious that although riveting can solve the pollution problem and ensure stability, in practice, after the shock absorber and the bracket are riveted, the distance between the shock absorber and the bracket cannot be adjusted, and naturally the height of the shock absorber cannot be adjusted. Therefore, it is a problem worth considering for technical personnel in this field to ensure that the connection between the shock absorber and the bracket is stable and flexible. Utility Model Content

[0006] In view of the above problems, the utility model proposes a height-adjustable bracket and sliding column assembly and shock absorber, comprising a bracket body, on which a shock absorber oil cylinder is vertically threadedly connected;

[0007] A locking block is coaxially sleeved on the shock absorber oil cylinder, and the locking block can be threadedly matched with the shock absorber oil cylinder until the locking block and the upper surface of the bracket body abut against each other to adjust the movement of the shock absorber oil cylinder relative to the bracket body in the height direction.

[0008] Preferably, the locking block is annular, and a locking thread is distributed on the inner annular surface, and the locking thread cooperates with the shock absorber oil cylinder along the vertical thread until the lower end surface of the locking block contacts the bracket body.

[0009] Preferably, the inner wall of the bracket body is provided with a threaded hole;

[0010] The axis of the shock absorber oil cylinder is vertical, and the cylinder body is distributed with external threads, which are matched with the threaded hole and the locking thread in sequence from bottom to top, and the outer diameter of the lower end surface of the locking block is larger than the inner diameter of the mounting screw hole.

[0011] Preferably, the shock absorber oil cylinder is cylindrical, and an external thread is arranged at the bottom end of the cylinder.

[0012] Preferably, protrusions for easy grasping are distributed on the outer annular surface of the locking block.

[0013] Preferably, the shock absorber oil cylinder body is provided with scale marks along the axial direction to indicate the height of the shock absorber oil cylinder adjusted relative to the bracket body.

[0014] Preferably, the support body and the shock absorber oil cylinder are made of aluminum.

[0015] The present application also claims protection for a height-adjustable sliding column assembly, including a sliding column structure installed above the shock absorber oil cylinder, wherein the bracket and the sliding column structure together constitute a sliding column assembly for speed reducer buffering.

[0016] The application also claims protection for a shock absorber, wherein the shock absorber is buffered by a strut assembly.

[0017] Beneficial Effects

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. Compared with the prior art in which the shock absorber oil storage cylinder is directly connected to the bracket body by welding, the present application firstly can adjust the extension height of the shock absorber oil cylinder by threading the shock absorber oil cylinder with the bracket body; secondly, after adjusting the appropriate height, the locking block can also be used to cooperate with the shock absorber oil cylinder thread until the locking block abuts against the upper surface of the bracket body, thereby locking the extension height of the shock absorber oil cylinder. In other words, the present application breaks the convention that the shock absorber oil cylinder cannot adjust the height. Not only can the height of the shock absorber oil cylinder be adjusted, but also the adjusted height can be further locked by the locking block after the height is adjusted.

[0020] 2. To be more specific, the locking block is annular, and has locking threads on the inner annular surface. The locking effect is achieved by the locking threads cooperating with the shock absorber oil cylinder along the vertical direction. It is specifically divided into two steps, namely, step 1, adjusting the height of the shock absorber oil cylinder. At this time, the locking block is rotated in the opposite direction so that the lower end face of the locking block and the bracket body are separated from each other. At this time, the extension distance of the shock absorber oil cylinder in the bracket body is adjusted by rotating the shock absorber oil cylinder in the opposite direction. Step 2, locking the height of the shock absorber oil cylinder. After adjusting the height, rotate the locking block in the forward direction so that the lower end face of the locking block and the bracket body are in conflict with each other, thereby limiting the movement of the shock absorber oil cylinder in the vertical direction.

[0021] 3. Furthermore, the outer ring surface of the locking block is provided with protrusions for easy grasping, so that people can hold and rotate the locking block easily.

[0022] 4. Furthermore, compared with the prior art, in which the bracket body and the shock absorber oil cylinder are both made of SAPH steel, resulting in an overall excessive weight, the present application uses aluminum, which is more conducive to lightweight product quality and more convenient for personnel adjustment.

[0033] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] The utility model claims a height-adjustable bracket. Obviously, the application can be applied to any two coaxially sleeved objects to adjust the height.

[0035] This embodiment mainly provides height adjustment of the shock absorber oil cylinder 20 and the bracket body 10 .

[0036] refer to Figure 1 , Figure 1 A schematic diagram of the assembly of a height-adjustable bracket and a shock absorber oil cylinder in an embodiment of the utility model is shown; wherein, the height-adjustable bracket comprises a bracket body 10, and a shock absorber oil cylinder 20 is vertically threadedly connected to the bracket body 10;

[0037] The damper oil cylinder 20 is coaxially sleeved with a locking block 30 , which can be threadedly matched with the damper oil cylinder 20 until the locking block 30 and the upper surface of the bracket body 10 abut against each other to adjust the movement of the damper oil cylinder 20 relative to the bracket body 10 in the height direction.

[0038] Compared with the prior art, in which the shock absorber oil cylinder 20 is directly connected to the bracket body 10 by welding, the present application firstly allows the shock absorber oil cylinder 20 to be threadedly connected to the bracket body 10 to adjust the extension height of the shock absorber oil cylinder 20; secondly, after adjusting the appropriate height, the locking block 30 can be threadedly matched with the shock absorber oil cylinder 20 until the locking block 30 abuts against the upper surface of the bracket body 10, thereby locking the extension height of the shock absorber oil cylinder 20. In other words, the present application breaks the convention that the shock absorber oil cylinder 20 cannot adjust the height, and can not only adjust the height of the shock absorber oil cylinder 20, but also further lock the adjusted height constantly through the locking block 30 after the height is adjusted.

[0039] refer to Figure 2 , Figure 2 A schematic diagram of the bracket body in an embodiment of the utility model is shown;

[0040] The bracket body 10 is provided with a threaded hole 11 .

[0041] The locking block 30 is annular, and a locking thread 31 is distributed on the inner annular surface, and a protrusion for easy grasping is distributed on the outer annular surface of the locking block 30.

[0042] refer to Figure 3 , Figure 3 A schematic diagram of a shock absorber oil cylinder in an embodiment of the utility model is shown;

[0043] The shock absorber oil cylinder 20 includes an oil storage cylinder 21 located at the bottom. The oil storage cylinder 21 is cylindrical and has an external thread arranged at the bottom of the cylinder. The external thread cooperates with the threaded hole 11 and the locking thread 31 from bottom to top, and the outer diameter of the lower end surface of the locking block 30 is larger than the inner diameter of the mounting screw hole.

[0044] The body of the shock absorber oil cylinder 20 is provided with scale marks along the axial direction, which can indicate the height of the shock absorber oil cylinder 20 adjusted relative to the bracket body 10.

[0045] The specific operation of the staff is divided into two stages: adjusting the height and locking the height, which include:

[0046] Step 1, adjust the height of the shock absorber oil cylinder 20. At this time, rotate the locking block 30 in the opposite direction so that the lower end surface of the locking block 30 and the bracket body 10 are separated from each other. At this time, by rotating the shock absorber oil cylinder 20 in the opposite direction, the extension distance of the shock absorber oil cylinder 20 in the bracket body 10 is adjusted.

[0047] Step 2, locking the height of the shock absorber oil cylinder 20, after adjusting the height, rotate the locking block 30 forward so that the lower end surface of the locking block 30 abuts against the bracket body 10, thereby limiting the movement of the shock absorber oil cylinder 20 in the vertical direction.

[0048] Here, for example, if the height of the shock absorber oil cylinder 20 needs to be raised, the operator needs to take the following actions;

[0049] First, the limiting effect of the rotating locking block 30 on the shock absorber oil cylinder 20 is released, that is, the rotating locking block 30 is rotated in the opposite direction so that the rotating locking block 30 moves up to not interfere with the shock absorber oil cylinder 20 .

[0050] Secondly, the shock absorber oil cylinder 20 is rotated in the opposite direction so that the shock absorber oil cylinder 20 is engaged with the bracket body 10, so that the shock absorber oil cylinder 20 moves upward relative to the bracket body 10. At this time, the operator can use the scale mark until it is adjusted to a suitable height.

[0051] Finally, the locking block 30 is rotated forward so that the lower end surface of the locking block 30 is tightly attached to the upper end surface of the bracket body 10. Therefore, the present application combines the limiting effect of the threaded engagement between the bracket body 10 and the shock absorber oil cylinder 20. On this basis, the locking block 30 is superimposed to further limit it, thereby achieving a double locking effect, and maintaining the adjusted height more stably.

[0052] It is worth mentioning here that in order to facilitate the operator to grip the locking block 30, the present application specially arranges a protrusion on the outer ring surface of the locking block 30. The main function is to prevent relative slipping when rotating the locking block 30. Therefore, the protrusion can be gear-shaped or frosted, and can even be provided with a sheath that makes the grip more comfortable depending on the situation. The present application does not impose too many restrictions.

[0053] Moreover, the support body 10 and the shock absorber oil cylinder 20 are made of aluminum. Compared with the prior art, the support body 10 and the shock absorber oil cylinder 20 are made of SAPH440 steel, which results in an overall overweight. The present application uses aluminum, which is more conducive to lightweight product quality and more convenient for personnel adjustment.

[0054] The present application also claims protection for a height-adjustable sliding column assembly, including a sliding column structure 22 installed above a shock absorber oil cylinder 20, wherein the bracket and the sliding column structure 22 together constitute a sliding column assembly for speed reducer buffering.

[0055] The application also claims protection for a shock absorber, which uses the strut assembly for buffering.

[0056] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
