Abstract
Description
Technical Field
[0001] This utility model relates to the field of shock absorber technology, specifically a segmented control damping automotive shock absorber. Background Technology
[0002] The term "shock absorber" is a common term in the automotive chassis industry. An automotive shock absorber is actually a vibration damper. Shock absorbers are used not only in the suspension of automobiles but also in other locations. For example, they are used in the driver's cab, seats, steering wheel, and can also be used as a buffer in vehicle bumpers.
[0003] Current shock absorbers only use one section of the shock absorption device for damping. When encountering road sections with varying road conditions, drivers and passengers will still experience significant bumps, which may cause motion sickness or other discomfort. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this invention provides a segmented control damping automotive shock absorber to solve the problems mentioned in the background section.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a segmented control damping automotive shock absorber, wherein a pull ring is fixedly installed on the bottom surface of the lower protective sleeve, an upper protective sleeve is provided on the upper side of the lower protective sleeve, a fixing block is fixedly installed on the inner top surface of the upper protective sleeve, a telescopic rod is fixedly installed on the bottom surface of the fixing block, a fixing block is fixedly installed on the inner bottom surface of the lower protective sleeve, an oil reservoir is fixedly installed on the top surface of the fixing block, the telescopic rod is movably disposed inside the oil reservoir, and an auxiliary spring is fixedly installed between the telescopic rod and the oil reservoir.
[0008] Preferably, the lower protective sleeve has a slope one on its side, and the upper protective sleeve has a slope two on its side.
[0009] Preferably, the telescopic rod includes a first telescopic rod, a first fixing plate is fixedly installed at the telescopic end of the first telescopic rod, a second telescopic rod is fixedly installed on the top surface of the first fixing plate, a second fixing plate is fixedly installed at the telescopic end of the second telescopic rod, a third telescopic rod is fixedly installed on the top surface of the second fixing plate, and a third fixing plate is fixedly installed on the top surface of the third telescopic rod.
[0010] Preferably, the top surfaces of the second and third fixed disks are provided with grooves, and the inner sides of the grooves are provided with movable plates one and two movable plates.
[0011] Preferably, an auxiliary spring is provided between the second fixed disk and the third fixed disk.
[0012] Preferably, the auxiliary springs are provided in several groups, which are evenly divided into three sets.
[0013] Compared with the prior art, this utility model provides a segmented control damping automotive shock absorber, which has the following beneficial effects:
[0014] 1. This segmented control damping car shock absorber firstly installs the shock absorber on the vehicle body at the location where shock absorption is needed through the pull rings on the upper and lower protective covers. When the vehicle encounters road bumps during driving, the weight of the vehicle body will cause the spring to compress after being pressed down by gravity. At this time, the hydraulic oil stored in the oil reservoir will flow upward through the groove, forming resistance. When the bumps are relatively easy, the third telescopic rod and the second telescopic rod can provide sufficient shock absorption for the vehicle body.
[0015] 2. This segmented control damping car shock absorber will extend and retract vertically when the shock absorber is working. The gap between the lower protective sleeve and the upper protective sleeve, created by inclined plane one and inclined plane two, can extend and retract to a certain extent. When there are large potholes, the entire telescopic rod will extend and retract to buffer and absorb shocks for the vehicle body. When the vibration ends, the tension between the vehicle body drives the compression between fixed plate two and fixed plate three, causing the hydraulic oil to flow back into the oil reservoir, preparing for the next shock absorption.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figure 1-4 As shown, this utility model provides a technical solution: a segmented control damping automotive shock absorber, wherein a pull ring 2 is fixedly installed on the bottom surface of the lower protective sleeve 1, an upper protective sleeve 3 is provided on the upper side of the lower protective sleeve 1, a fixing block 4 is fixedly installed on the inner top surface of the upper protective sleeve 3, a telescopic rod 7 is fixedly installed on the bottom surface of the fixing block 4, a fixing block 4 is fixedly installed on the inner bottom surface of the lower protective sleeve 1, an oil reservoir 5 is fixedly installed on the top surface of the fixing block 4, the telescopic rod 7 is movably disposed inside the oil reservoir 5, and an auxiliary spring 8 is fixedly installed between the telescopic rod 7 and the oil reservoir 5.
[0023] Furthermore, the side of the lower protective sleeve 1 is provided with a slope 101, and the side of the upper protective sleeve 3 is provided with a slope 301.
[0024] With the above technical solution, the shock absorber will expand and contract vertically when it is working. The gap between the lower protective sleeve 1 and the upper protective sleeve 3, created by inclined surface 101 and inclined surface 301, can expand and contract to a certain extent.
[0025] Furthermore, the telescopic rod 7 includes a first telescopic rod 701, a first fixing plate 707 fixedly installed at the telescopic end of the first telescopic rod 701, a second telescopic rod 702 fixedly installed on the top surface of the first fixing plate 707, a second fixing plate 708 fixedly installed at the telescopic end of the second telescopic rod 702, a third telescopic rod 703 fixedly installed on the top surface of the second fixing plate 708, and a third fixing plate 709 fixedly installed on the top surface of the third telescopic rod 703.
[0026] The above technical solution allows the segmented telescopic rods to achieve segmented shock absorption when the car encounters bumpy road sections, resulting in better cushioning and stability.
[0027] Furthermore, the top surfaces of the second fixed plate 708 and the third fixed plate 709 are provided with grooves 704, and the inner side of the grooves 704 is provided with movable piece 705 and movable piece 706.
[0028] Through the commercially available technical solution, the hydraulic oil inside the oil reservoir 5 can achieve a shock absorption and buffering effect through the groove 704. The movable plate 1 705 and movable plate 2 706 can control the flow rate when the hydraulic oil passes through, making the overall buffering process more stable.
[0029] Furthermore, an auxiliary spring 8 is provided between the second fixed plate 708 and the third fixed plate 709.
[0030] Through the above technical solution, the auxiliary spring 8 can improve the shock absorption effect of the telescopic rod. When encountering large potholes on the road surface, if the number of springs is too small, the impact force will increase during downward movement, resulting in ineffective shock absorption and cushioning.
[0031] Furthermore, the auxiliary springs 8 are provided in several groups, which are evenly divided into three sets.
[0032] With the above technical solution, each fixed plate is equipped with an auxiliary spring-type 8-segment auxiliary telescopic rod for buffering and shock absorption.
[0033] Working principle: The shock absorber is installed on the vehicle body at the position where shock absorption is required through the pull ring 2 on the upper protective sleeve 3 and the lower protective sleeve 1. When the vehicle encounters bumps on the road during driving, the weight of the vehicle body will cause the spring 6 to be compressed after being pressed down by gravity. At this time, the hydraulic oil stored in the oil reservoir will flow upward through the groove 704, forming resistance. When the bumps are relatively mild, the third telescopic rod 703 and the second telescopic rod 702 can provide sufficient shock absorption for the vehicle body. When the bumps are large, the entire telescopic rod will extend and retract to buffer and absorb the shock for the vehicle body. When the vibration ends, the tension between the vehicle bodies will cause the fixed plate 2 708 and the fixed plate 3 709 to squeeze together, so that the hydraulic oil flows back into the oil reservoir 5, preparing for the next shock absorption.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
