Description

Technical Field

[0001] The utility model relates to the technical field of vehicle shock absorbers, in particular to a vehicle shock absorber with stable installation. Background Art

[0002] Shock absorbers are used to suppress the shock caused by the rebound of springs after shock absorption and the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of frame and body vibrations to improve the driving smoothness of the car. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump. With the continuous development of automobile technology, the requirements for automobile driving stability and ride comfort are increasing. As an important part of the automobile suspension system, the installation stability and performance of the automotive shock absorber have an important impact on the driving stability and ride comfort of the car.

[0003] According to Chinese patent announcement number CN 210510089 U3, a vehicle shock absorber is disclosed, which relates to the technical field of shock absorbers, and includes a mounting seat, an inlet rod, and an oil storage cylinder, wherein the mounting seat and the oil storage cylinder are respectively located at both ends of the inlet rod, and a buffer sleeve is sleeved on one end of the inlet rod close to the mounting seat, and the buffer sleeve includes an upper sleeve body and a lower sleeve body in the direction from the mounting seat toward the oil storage cylinder, the inner wall of the upper sleeve body and the side wall of the inlet rod are interference-fitted, and the inner wall of the lower sleeve body and the side wall of the inlet rod are clearance-fitted. The utility model solves the problem of difficulty in installing the buffer sleeve.

[0004] However, the above-mentioned vehicle shock absorbers have problems such as cumbersome operation and poor stability during installation and removal. At the same time, the shock absorption effect is single and cannot meet the needs of different road conditions and driving. Utility Model Content

[0005] The purpose of the utility model is to provide a vehicle shock absorber with stable installation to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a vehicle shock absorber with stable installation, comprising a main body mechanism, wherein an auxiliary mechanism is arranged inside the main body mechanism;

[0007] The main body mechanism includes a mounting plate, a connecting seat is fixedly connected to the bottom of the mounting plate, a mounting groove is provided at the bottom of the connecting seat, an outer cylinder is movably connected to the mounting groove, a first groove is provided inside one end of the outer cylinder, a sliding rod is fixedly connected to the inner wall of the first groove, a first spring is sleeved on the outside of the sliding rod, blocks are fixedly connected to both ends of the first spring, an auxiliary ring is threadedly connected to the outside of the outer cylinder, a first fixing block is fixedly connected to the outer surface of the outer cylinder, a piston rod is movably connected to the inside of the outer cylinder, an end of the piston rod away from the outer cylinder is fixedly connected to the second fixing block, a shock-absorbing spring is sleeved on the outer side of the outer cylinder and the piston rod, a connecting rod is fixedly connected to the bottom of the second fixing block, and a connecting ring is fixedly connected to the bottom of the connecting rod.

[0008] Furthermore, first, the outer cylinder is placed in the installation groove at the bottom of the connecting seat, and then, by turning the auxiliary ring downward, the inner wall of the auxiliary ring releases the squeezing of one end of the card block, and the elastic force of the first spring causes the card block to move toward the outside of the outer cylinder, driving the other end of the card block to enter the card groove opened on the inner wall of the connecting seat, completing the installation of the outer cylinder and the connecting seat, and the second groove on the inner wall of the auxiliary ring can ensure that the card block stays stably inside to prevent unlocking caused by accidental touch. When disassembly is required, by turning the auxiliary ring upward, the inner wall of the auxiliary ring presses one end of the card block into the first groove opened inside one end of the outer cylinder, and at the same time drives the other end of the card block from the inside of the card groove into the inside of the first groove, unlocking the lock between the outer cylinder and the connecting seat, so that the outer cylinder can be easily taken out, and through the cooperation of the auxiliary ring and the card block, the outer cylinder and the connecting seat can be easily installed and disassembled quickly, which is convenient for maintenance and replacement, and the sliding connection of the card block on the slide rod and the elastic force of the first spring ensure that the card block can be stably locked or unlocked, thereby improving the structural stability of the shock absorber.

[0009] Preferably, threaded holes are provided at four corners of the mounting plate, and bolts are rotatably connected inside the threaded holes.

[0010] Furthermore, threaded holes are provided at the four corners of the mounting plate for fixing the shock absorber to the vehicle by bolts to ensure the stability of the installation. By rotating the bolts, the shock absorber can be firmly fixed to the vehicle to ensure its stability during driving.

[0011] Preferably, the block is slidably connected to the outer surface of the slide rod.

[0012] Further, the block can slide on the slide bar. Through the elastic force of the first spring, the block can move along the slide bar.

[0013] Preferably, both ends of the block pass through the outer cylinder and extend to the outside of the outer cylinder, the inner wall of the installation groove is provided with a groove matched with one end of the block, and the inner wall of the auxiliary ring is provided with a second groove matched with the other end of the block.

[0014] Furthermore, by rotating the auxiliary ring upward, the inner wall of the auxiliary ring presses one end of the card block into the first groove opened inside one end of the outer cylinder, and then drives the other end of the card block from the inside of the card groove into the inside of the first groove, unlocks the lock between the outer cylinder and the connecting seat, and takes out the outer cylinder. By rotating the auxiliary ring downward, the inner wall of the auxiliary ring releases the squeezing of one end of the card block, and one end of the card block moves toward the outside of the outer cylinder, driving the other end of the card block into the card groove opened on the inner wall of the connecting seat, completing the installation of the outer cylinder and the connecting seat. The second groove opened on the inner wall of the auxiliary ring and adapted to the other end of the card block can allow the other end of the card block to stay in the second card groove to avoid accidental touch from the outside.

[0015] Preferably, two ends of the shock-absorbing spring are fixedly connected to the bottom of the first fixing block and the top of the second fixing block respectively.

[0016] Furthermore, the shock-absorbing spring is one of the core components of the shock absorber. It is located between the outer tube and the piston rod. The two ends of the shock-absorbing spring are respectively fixedly connected to the bottom of the first fixed block and the top of the second fixed block. When the vehicle is vibrated, the shock-absorbing spring will deform, driving the piston rod to expand and contract, thereby absorbing and buffering vibrations. The stiffness and stroke of the shock-absorbing spring can be designed as needed to meet the requirements of different vehicles and driving conditions.

[0017] Preferably, the auxiliary mechanism comprises a screw rod, and a slider is threadedly connected to the surface of the screw rod.

[0018] Furthermore, when the vehicle vibrates during driving, the piston rod moves in the outer cylinder, and the slider connected to the outside of the piston rod moves on the screw rod. Due to the threaded connection between the screw rod and the slider, the screw rod will rotate. During this rotation process, due to friction, viscosity or other resistance mechanisms inside the material, a damping force will be generated, which will relieve part of the pressure, thereby reducing the continued downward pressure of the vehicle body and improving ride comfort.

[0019] Preferably, a slide groove is provided inside the outer cylinder, the screw rod is arranged in the slide groove provided inside the outer cylinder, and the sliding block is fixedly connected to the outer surface of the piston rod.

[0020] Furthermore, by fixing the two screw rods in the slide grooves opened on the inner wall of the outer cylinder respectively, and by connecting the two sliders to the outer surface of the piston rod, the two sliders are driven to move on the surfaces of the two sliders when the piston rod is extended or retracted. The screw rods on both sides will rotate due to the threaded connection with the connecting block to relieve part of the pressure and convert it into damping force. During the rotation of the screw rods, damping force will be generated due to friction, viscosity or other resistance mechanisms inside the material. This damping force can relieve part of the pressure, thereby reducing the continued downward pressure of the vehicle body.

[0021] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0022] The second groove on the inner wall of the auxiliary ring can ensure that the card block stays stably inside to prevent unlocking caused by accidental touch. When disassembly is required, the auxiliary ring can be rotated upward so that the inner wall of the auxiliary ring presses one end of the card block into the first groove inside one end of the outer cylinder, and at the same time drives the other end of the card block from the inside of the card groove into the inside of the first groove, thereby unlocking the lock of the outer cylinder and the connecting seat, so that the outer cylinder can be easily taken out. Through the cooperation of the auxiliary ring and the card block, the quick installation and disassembly of the outer cylinder and the connecting seat can be easily realized, which is convenient for maintenance and replacement. The sliding connection of the card block on the slide bar and the elastic force of the first spring ensure that the card block can be stably locked or unlocked, thereby improving the structural stability of the shock absorber.

[0023] Second, when the vehicle vibrates during driving, the piston rod moves in the outer cylinder, and the slider connected to the outside of the piston rod moves on the screw rod. Due to the threaded connection between the screw rod and the slider, the screw rod will rotate. During this rotation, due to the friction, viscosity or other resistance mechanisms inside the material, a damping force will be generated to relieve part of the pressure, thereby reducing the continued downward pressure on the vehicle body and improving ride comfort.
