Description

Technical Field

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

[0002] Shock absorbers can improve the smoothness of a car's ride. In the suspension system, elastic elements generate vibrations due to impact. Installing shock absorbers in parallel with the elastic elements in the suspension can reduce the impact force, thereby improving the driver's experience and comfort.

[0003] The current shock absorbers have certain defects. Due to the dual-cylinder structure of oil and gas, when the shock absorber leaks oil due to long-term driving of the car and sudden accidents, the overall capacity of the shock absorber will disappear. In severe cases, it will cause the collapse of the car body, which will cause serious damage to the car suspension.

[0004] Therefore, an adjustable automobile shock absorber is provided to solve the above problems. Utility Model Content

[0027] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0028] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0029] An adjustable automobile shock absorber provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0030] Example 1:

[0031] Combine Figures 1-4 As shown, the utility model provides an adjustable automobile shock absorber, including a shock absorber mechanism 100 and a spacing adjustment mechanism 200 arranged outside the shock absorber mechanism 100. The shock absorber mechanism 100 is used to support the automobile suspension system, and the spacing adjustment mechanism 200 is used to increase the overall height of the shock absorber mechanism 100.

[0032] The shock absorber mechanism 100 includes an oil cylinder 110, an oil seal cover 120, a support rod 130, a top adapter 140 and a spring 150, and the spacing adjustment mechanism 200 includes a first pressure-resistant sleeve 210, a base 220, a bottom adapter 230, a locking bolt 240, a positioning pin 250, an adjusting gear ring 260, a top seat 270, a second pressure-resistant sleeve 280 and a fastening bolt 290.

[0033] The shock absorber mechanism 100 includes a cylinder 110 and a support rod 130 movably mounted inside the cylinder 110 ;

[0034] The spacing adjustment mechanism 200 includes a first pressure-resistant sleeve 210 and a second pressure-resistant sleeve 280 movably mounted on the outside of the oil cylinder 110, a base 220 fixedly mounted on the top end of the first pressure-resistant sleeve 210, a top seat 270 fixedly mounted on the bottom end of the second pressure-resistant sleeve 280, and an adjustment gear ring 260 movably mounted between the base 220 and the top seat 270.

[0035] Since the car shock absorber serves as the support of the bicycle suspension system, when the car is used for a long time and the external spring of the shock absorber is fatigued, if the car is continuously positioned and driven on bumpy roads, the oil cylinder or air cylinder of the shock absorber will be damaged due to the excessive impact force, and in severe cases, it will cause the collapse of the car suspension system.

[0036] The device is provided with a height-adjustable spacing mechanism 200 on the outside of the oil cylinder shell of the automobile shock absorber. When the two adjusting tooth rings 260 are taken out from the two threaded sleeves at the bottom of the base 220, the adjusting tooth rings 260 can be rotated clockwise with a wrench. At this time, the adjusting tooth rings 260 will help the oil cylinder 110 to lift upward. When the spring 150 is fatigued and the elastic force decreases, the spacing between the shock absorber mechanism 100 and the first pressure-resistant sleeve 210 can be shortened. At this time, the oil cylinder 110 and the support rod 130 as a whole can cooperate with the fatigued spring 150 to provide protection for the vehicle body. At this time, the safety of the car can be improved without replacing the spring 150.

[0037] Example 2:

[0038] Combine Figure 2-Figure 3 As shown, based on Example 1, the shock absorber mechanism 100 further includes an oil seal cover 120 mounted on the bottom of the oil cylinder 110, a top adapter 140 fixedly mounted on the top of the support rod 130, and a spring 150 bearing pressure on the bottom of the top adapter 140;

[0039] The outside of the oil cylinder 110 is provided with threads.

[0040] By setting the spring 150 between the spring 150 and the top seat 270, the spring 150 can cooperate with the oil cylinder and the air cylinder to achieve triple shock absorption protection. Since the external spring 150 is exposed to the external environment for a long time, it is most likely to cause its internal elastic force to decrease due to fatigue. Therefore, by adjusting the rotation of the adjustment ring 260 until the oil cylinder 110 is properly boosted, the height of the oil cylinder 110 and the first pressure-resistant sleeve 210 can be appropriately reduced. At this time, the impact force on the oil cylinder and the air cylinder can be reduced without replacing the fatigue spring 150. The four shock absorbers of the car are adjusted synchronously to ensure the balance of the car body shock absorption.

[0041] Example 3:

[0042] Combine Figure 2-Figure 4 As shown, based on Example 1, the spacing adjustment mechanism 200 further includes a bottom adapter 230 provided at the bottom of the first pressure-resistant sleeve 210 and multiple sets of locking bolts 240 installed in the first pressure-resistant sleeve 210 and the bottom adapter 230;

[0043] A hollow observation window is provided inside the locking bolt 240;

[0044] The top adapter 140 and the bottom adapter 230 are both made of chrome-plated alloy, and the top adapter 140 has multiple evenly distributed notches formed inside.

[0045] A first annular groove is formed on the top of the base 220, and a second annular groove is formed on the bottom of the top seat 270;

[0046] Multiple sets of fastening bolts 290 are evenly distributed and installed in the base 220 and the top seat 270;

[0047] Two threaded sleeves are installed at the bottom of the base 220, and positioning pins 250 are installed in the threaded sleeves;

[0048] The positioning pin 250 is composed of a hexagonal end, a threaded end rod and an insert rod;

[0049] The outside of the adjusting toothed ring 260 is provided with uniformly distributed teeth, and the inside of the adjusting toothed ring 260 is provided with a plurality of circumferentially distributed insertion holes, and the insertion rods are adapted to pass through the insertion holes.

[0050] By providing an observation window in the bottom adapter 230, when the oil cylinder leaks oil due to impact force, the sealing performance of the oil seal can be observed in real time through the observation window. By installing two locating pins 250 in the two threaded sleeves at the bottom of the base 220, and using the two locating pins 250 to conveniently position the internal sockets of the adjusting gear ring 260, the rotating adjusting gear ring 260 can prevent the oil cylinder 110 from reversing due to excessive external force.

[0051] The working principle and usage process of the present invention are as follows: after the top adapter 140 and the bottom adapter 230 are assembled with the vehicle body and the vehicle suspension, the strut 130 and the oil cylinder 110 in the initial state can provide shock-absorbing support for the vehicle. When the assembled strut 130, the oil cylinder 110 and the spacing adjustment mechanism 200 exert too low pressure on the vehicle body and the vehicle suspension, the worker can unscrew the two locating pins 250 counterclockwise, and then use a wrench to adjust the adjusting gear ring 260 and rotate it clockwise. At the same time, the oil cylinder 110 movably installed inside the first pressure-resistant sleeve 210 and the second pressure-resistant sleeve 280 will be pushed upward by the adjusting gear ring 260 until the shock absorber mechanism 100 and the spacing adjustment mechanism 200 are stretched to the required height. The two locating pins 250 can then be screwed back into the two screw sleeves at the bottom of the base 220 until the two locating pins 250 fix the adjusted adjusting gear ring 260.

[0052] When the spring 150 has been used for a long time and the torque is reduced due to fatigue, the two positioning pins 250 are first removed according to the above adjustment method, and the adjusting gear ring 260 is controlled to rotate in the opposite direction until the oil cylinder 110 descends to a certain height toward the inner cavity of the first pressure-resistant sleeve 210, and then the two positioning pins 250 can be fixed in the adjusting gear ring 260 again;

[0053] When the car is traveling on a complex road section and causes the shock absorber to malfunction, the above two methods can provide emergency shock absorption protection for the car during a special time period.

[0054] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
