[0002] Automotive shock absorbers are key components in the automotive chassis system, mainly used to reduce and suppress vibrations and impacts caused by uneven road surfaces or other factors during vehicle driving, improving driving comfort and stability. An automotive shock absorber is a vibration damper, mainly used to suppress vibrations during the rebound of the spring after absorbing shock and vibrations from the road surface. It can reduce the vibration amplitude of the vehicle frame and body, effectively improving the comfort and smoothness of the vehicle during driving. Automotive shock absorbers are vulnerable parts in the automotive structure, and the quality of their working conditions is directly related to the service life of other vehicle components and driving safety. The main function of an automotive shock absorber is to suppress the vibration deformation of the spring during absorption and the shock during spring rebound, while absorbing the impact force from the road surface.

[0003] Currently, in the prior art, an automotive shock absorber mainly consists of a cylinder body, a cylinder, a piston, a piston rod, a telescopic spring, and a base. It uses the movement of the piston inside the cylinder to achieve the damping effect, thereby reducing vehicle vibrations and compressing the rebound vibration of the spring inside the automotive shock absorber. During actual use, lubricating oil needs to be added to the inside of the cylinder, which requires the staff to loosen multiple fastening bolts each time the base on the cylinder is opened, making disassembly rather troublesome. Therefore, an automotive shock absorber with self-lubrication is proposed to solve the above problems. Content of the Utility Model

[0007] Furthermore, four balls are rotatably installed inside the shock absorber cylinder body. A connecting sleeve for cooperating with the rolling of the balls is fixedly installed on the outer surface of the cylinder block. A support seat is fixedly installed on the left side of the shock absorber cylinder body. A locking assembly is installed at one end of the support seat and the piston rod.

[0008] Furthermore, the piston is slidably installed inside the cylinder block. The piston is fixedly connected to the piston rod. The piston rod is slidably connected to the cylinder block. A shock-absorbing spring is sleeved on the outer surface of the piston rod.

[0009] Furthermore, an annular groove is provided on the inner peripheral wall of the threaded collar. The two connecting blocks are both slidably installed inside the annular groove.

[0010] Furthermore, installation grooves are provided at both the top and bottom of the base. A limiting strip is fixedly installed on the rear side wall of the inner cavity of the installation groove. A limiting groove is provided on the back surface of the abutting block. The inner wall of the limiting groove is slidably connected to the outer surface of the limiting strip.

[0015] This self-lubricating automotive shock absorber is provided with a base, which facilitates the staff to rotate the threaded collar and control its movement to the right. As a result, the moving threaded collar drives two connecting blocks to move to the right. The connecting blocks drive the abutting blocks to move synchronously, thus releasing the position restriction on the two positioning beads. This enables the staff to extract the base and the exhaust valve, and then conveniently add lubricating oil through the hole on one side of the cylinder block where the exhaust valve is inserted. Moreover, a connecting sleeve is provided on the outer surface of the cylinder block, and by using the balls installed on the shock absorber cylinder, the connecting sleeve slides more smoothly under the action of the balls during the sliding of the cylinder block, thereby reducing wear and increasing the service life, enhancing the practicality of this self-lubricating automotive shock absorber.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 3 , a self-lubricating automotive shock absorber in this embodiment includes a shock absorber cylinder 1. A cylinder block 2 is disposed inside the shock absorber cylinder 1 with one end penetrating and extending to its outside. A piston 4 is installed inside the cylinder block 2. One side of the piston 4 is provided with a piston rod 5 that penetrates and extends to the outside of the cylinder block 2. The piston 4 is slidably installed inside the cylinder block 2. The piston 4 is fixedly connected to the piston rod 5. The piston rod 5 is slidably connected to the cylinder block 2. A shock spring 6 is sleeved on the outer surface of the piston rod 5.

[0022] In this example implementation, a base 7 is sleeved on the right side of the cylinder block 2. An exhaust valve 8 is fixedly installed inside the base 7, with one end passing through and extending into the interior of the cylinder block 2. Two positioning beads 9 for fixing the cylinder block 2 are installed inside the base 7. Two fixing grooves are provided on the cylinder block 2. One end of each of the two positioning beads 9 passes through the installation groove and extends into the interior of the fixing groove, facilitating the insertion of the positioning beads 9 into the fixing grooves to achieve the fixation of the cylinder block 2 and the base 7. Two abutting blocks 10 for abutting against the positioning beads 9 are slidably installed inside the base 7. Installation grooves are provided at the top and bottom of the base 7. A limiting strip is fixedly installed on the rear side wall of the inner cavity of the installation groove. A limiting groove is provided on the back surface of the abutting block 10, and the inner wall of the limiting groove is slidably connected to the outer surface of the limiting strip, facilitating the restriction of the sliding trajectory of the abutting block 10 and also restricting the detachment of the positioning beads 9. A threaded collar 11 is threadedly installed on the outer surface of the base 7. Two connecting blocks 12 are slidably installed on the inner peripheral wall of the threaded collar 11. The opposite sides of the two connecting blocks 12 are respectively fixedly connected to the opposite sides of the two abutting blocks 10.

[0023] Among them, an annular groove is provided on the inner peripheral wall of the threaded collar 11, and the two connecting blocks 12 are both slidably installed inside the annular groove, facilitating the sliding of the connecting blocks 12 inside the annular groove when the threaded collar 11 rotates, so that the connecting blocks 12 can be driven to move synchronously when the threaded collar 11 moves to one side.

[0024] With the above technical solution, the threaded collar 11 threadedly connected to the outer surface of the rotating base 7 is realized, so that the threaded collar 11 drives the two connecting blocks 12 to move to the right, thereby driving the abutting blocks 10 to move synchronously by the moving connecting blocks 12, thus releasing the position restriction on the two positioning beads 9, and further facilitating the staff to withdraw the sleeved base 7 and the exhaust valve 8 from the cylinder block 2, so as to facilitate adding lubricating oil into the cylinder block 2 through the hole where the exhaust valve 8 is installed.

[0025] In this example implementation, four balls 13 are rotatably installed inside the shock absorber cylinder 1. A connecting sleeve 3 for cooperating with the rolling of the balls 13 is fixedly installed on the outer surface of the cylinder block 2. A support seat 14 is fixedly installed on the left side of the shock absorber cylinder 1. Two locking bolts are provided on the support seat 14. One end of each of the two locking bolts passes through the shock absorber cylinder 1 and extends into the interior of the support seat 14.

One end of the threaded column is fixedly connected to one end of the piston rod 5. One end of the threaded column passes through to the interior of the support seat 14, and a nut is threadedly installed on the threaded column, facilitating the release of the connection between the piston rod 5 and the support seat 14.

[0026] Among them, four guiding grooves are formed on the outer surface of the connecting sleeve 3, and one end of the ball 13 penetrates and extends into the interior of the guiding groove, so as to facilitate restricting the rolling of the ball 13 within the guiding groove, and realizing the sliding between the supporting connecting sleeve 3 and the shock absorber cylinder body 1.

[0027] By adopting the above technical solution, the two locking bolts on the supporting seat 14 are removed, and then the nut in the locking assembly 15 is rotated, so as to release the position fixation of the supporting seat 14, facilitating the staff to draw out the supporting seat 14, thus opening the shock absorber cylinder body 1, and further facilitating adding lubricating oil into the shock absorber cylinder body 1. Moreover, by utilizing the cooperative sliding of the ball 13 and the connecting sleeve 3, the wear is reduced and the service life is prolonged.

[0028] The working principle of the above embodiment is as follows:

[0029] For this self-lubricating vehicle shock absorber, when disassembling and adding lubricating oil, the two locking bolts on the supporting seat 14 are removed, and then the nut in the locking assembly 15 is rotated to release the position fixation of the supporting seat 14, facilitating the staff to draw out the supporting seat 14, thus opening the shock absorber cylinder body 1. Then, the threaded collar 11 threadedly connected to the outer surface of the base 7 is rotated, so that the threaded collar 11 drives the two connecting blocks 12 to move to the right, thereby driving the abutting block 10 to move synchronously by the moving connecting blocks 12, thus releasing the position restriction on the two positioning beads 9, and further facilitating the staff to draw out the sleeved base 7 and the exhaust valve 8 from the cylinder block 2, so as to facilitate adding lubricating oil into the cylinder block 2 through the hole where the exhaust valve 8 is installed. Moreover, by utilizing the cooperative sliding of the ball 13 and the connecting sleeve 3, the wear is reduced and the service life is prolonged.
