Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to an automobile shock absorber with adjustable damping force. Background Art

[0002] Shock absorbers are key components in a vehicle's suspension system. Their primary function is to absorb impact and vibration caused by uneven roads or poor driving conditions, maintaining vehicle smoothness and improving ride comfort while ensuring steering and braking functions are not affected, thereby enhancing driving safety. 12 Shock absorbers generate damping force through their internal hydraulic or pneumatic systems. When the wheel bounces up and down, the piston inside the shock absorber moves in the oil or gas. The flow of oil or gas through the narrow channel generates friction. This friction, along with the internal friction between the oil molecules, creates a damping force, converting the vehicle's kinetic energy into heat energy, thereby absorbing the vibration energy.

[0003] The damping force of existing automobile shock absorbers is often fixed. Under different road conditions, such as flat roads and rugged mountain roads, shock absorbers with fixed damping force cannot provide the best shock absorption effect, resulting in certain limitations in the use of existing shock absorbers. Utility Model Content

[0004] The purpose of the utility model is to provide a shock absorber for an automobile with adjustable damping force, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a shock absorber for automobile with adjustable damping force, comprising a connecting member 1,

[0006] and a shock absorbing assembly arranged at a bottom position of the connecting member;

[0007] The shock absorbing assembly includes an adjustment mechanism arranged at a bottom position of the connecting member;

[0008] A shock absorbing mechanism is installed at the bottom of the first connecting member, and the shock absorbing mechanism is connected to the adjusting mechanism.

[0009] Preferably, the shock absorbing mechanism includes a moving part, which is fixedly mounted on the bottom of the connecting part 1, a piston rod is fixedly mounted on the bottom of the moving part, a working cylinder is slidably mounted on the side wall of the piston rod, and a shock absorbing spring is fixedly mounted on the bottom of the moving part.

[0010] Preferably, the piston rod is located inside the shock-absorbing spring, and a second connecting member is fixedly installed on the bottom of the working cylinder.

[0011] Preferably, the adjusting mechanism includes a threaded sleeve, the inner wall of the threaded sleeve is fixedly connected to the side wall of the working cylinder, the side wall of the threaded sleeve is installed with a rotating disk, the inner wall of the rotating disk with an arc groove is slidably installed with a connecting ring, the side wall of the connecting ring is fixedly installed with a circular ring, the side wall of the circular ring is fixedly installed with a connecting pad, and the side wall of the connecting pad is fixedly connected to one end of the shock-absorbing spring.

[0012] Preferably, a protrusion is fixedly mounted on the side wall of the rotating disk, and the inner wall of the rotating disk is threadedly connected to the side wall of the threaded sleeve. When the rotating disk rotates, its position can be adjusted.

[0013] Preferably, the side wall of the circular ring is slidably connected to the side wall of the rotating disk, and the side wall of the connecting pad is slidably connected to the side wall of the rotating disk.

[0014] Preferably, there are multiple protrusions, the shapes and sizes of the multiple protrusions are equal, and the multiple protrusions are evenly distributed on the side walls of the rotating disk.

[0015] The utility model provides a shock absorber for automobiles with adjustable damping force, which has the following beneficial effects:

[0016] (1) When the operator needs to adjust the damping force, the utility model can directly rotate the position of the protrusion, and the protrusion drives the position of the rotating disk to rotate. Since the inner wall of the rotating disk is threadedly connected to the side wall of the circular ring, the rotating disk can drive its own position to move when it rotates. The rotating disk further drives the positions of the circular ring, the connecting ring and the connecting pad to move. The connecting pad will adjust the position of one end of the shock-absorbing spring, thereby adjusting the damping force of the shock absorber, solving the problem that the damping force of the existing automobile shock absorber is often fixed. Under different road conditions, such as flat roads and rugged mountain roads, the shock absorber with fixed damping force cannot provide the best shock absorption effect, resulting in certain limitations when the existing shock absorber is used.

[0017] (2) The utility model installs the device as a whole on the car through the connecting piece 1 and the connecting piece 2. When the car vibrates, the piston rod will slide on the inner wall of the working cylinder. At this time, the moving part will also squeeze one end of the shock-absorbing spring when it moves. The two parts work together to achieve the shock-absorbing function, which is convenient for the operator to use the device better. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings.

[0027] Example 1: A preferred embodiment of a shock absorber for automobile with adjustable damping force provided by the present invention is as follows: Figures 1 to 4 As shown: A shock absorber for automobile with adjustable damping force, including a connecting member 1,

[0028] and a shock absorbing assembly 4 provided at the bottom of the connecting member 1;

[0029] The shock absorbing assembly 4 includes an adjusting mechanism 41 arranged at the bottom position of the connecting member 1;

[0030] A shock absorbing mechanism 42 is installed at the bottom of the connecting member 1, and the shock absorbing mechanism 42 is connected to the adjusting mechanism 41.

[0031] The adjusting mechanism 41 includes a threaded sleeve 412, the inner wall of the threaded sleeve 412 is fixedly connected to the side wall of the working cylinder 424, the side wall of the threaded sleeve 412 is installed with a rotating disk 416, the inner wall of the rotating disk 416 with an arc groove is slidably installed with a connecting ring 415, the side wall of the connecting ring 415 is fixedly installed with a circular ring 414, the side wall of the circular ring 414 is fixedly installed with a connecting pad 413, and the side wall of the connecting pad 413 is fixedly connected to one end of the shock-absorbing spring 423.

[0032] In this embodiment, a protrusion 417 is fixedly mounted on the side wall of the rotating disk 416 , and the inner wall of the rotating disk 416 is threadedly connected to the side wall of the threaded sleeve 412 . The position of the rotating disk 416 can be adjusted when it rotates.

[0033] Furthermore, the side wall of the circular ring 414 is slidably connected to the side wall of the rotating disk 416 , and the side wall of the connecting pad 413 is slidably connected to the side wall of the rotating disk 416 .

[0034] Furthermore, there are multiple protrusions 417 , and the shapes and sizes of the multiple protrusions 417 are equal. The multiple protrusions 417 are evenly distributed on the side walls of the rotating disk 416 .

[0035] During the specific implementation process, when the operator needs to adjust the damping force, he can directly rotate the position of the protrusion 417, and the protrusion 417 drives the position of the rotating disk 416 to rotate. Since the inner wall of the rotating disk 416 is threadedly connected to the side wall of the ring 414, the rotating disk 416 can drive its own position to move when it rotates. The rotating disk 416 further drives the position of the ring 414, the connecting ring 415 and the connecting pad 413 to move, and the connecting pad 413 will adjust the position of one end of the shock-absorbing spring 423, thereby adjusting the damping force of the shock absorber.

[0038] During the specific implementation process, when the operator uses the device, he first installs the entire device on the car through connecting piece 1 and connecting piece 2. When the car vibrates, the piston rod 422 will slide on the inner wall of the working cylinder 424. At this time, the moving part 421 will also squeeze one end of the shock-absorbing spring 423 when moving. The two parts work together to achieve the shock-absorbing function.
