Description

Technical Field

[0001] The utility model belongs to the technical field of automotive parts, and particularly relates to an automotive shock absorber bracket which is convenient for installation. Background Art

[0002] In order to rapidly attenuate the vibration of the vehicle frame and the vehicle body and improve the ride comfort and smoothness of the vehicle, shock absorbers are generally installed on the vehicle suspension system; the automotive shock absorber bracket is used to connect the automotive shock absorber and the automotive drive axle. The automotive shock absorber bracket is fixedly welded to the automotive drive axle, and the shock absorber is fixedly connected to the shock absorber bracket, playing a role in supporting and buffering energy absorption, so that the vehicle maintains good comfort and handling stability. However, the connection structure between the shock absorber and the bracket is relatively complex, resulting in inconvenience when disassembling and overhauling the shock absorber.

[0003] For example, an automotive shock absorber bracket with the patent publication number CN220037319U includes a base, a connecting sleeve, a clamping sleeve, a shock absorber, a buffer mechanism, a friction mechanism, fastening bolts and nuts. A connecting sleeve is fixed to the lower side of the base, a clamping sleeve is detachably connected to the connecting sleeve, multiple fastening bolts penetrating the connecting sleeve are installed on the clamping sleeve, a nut is installed on each fastening bolt, a shock absorber is connected between the connecting sleeve and the clamping sleeve, the lower end of the shock absorber extends to the outside of the connecting sleeve, and a buffer mechanism and a friction mechanism are installed at the upper end inside the connecting sleeve. The buffer mechanism includes: a piston block, a limiting guide rod and a compression spring. Multiple compression springs fixed to the connecting sleeve are installed on the upper side of the piston block, and a limiting guide rod is installed at the middle position on the upper side of the piston block. The utility model is convenient for disassembling the shock absorber and is convenient for overhaul; it has a buffering function and has a better shock absorption effect when used in cooperation with the shock absorber.

[0004] However, the above has the following deficiencies:

[0005] 1. In the above patent, although the detachable clamping sleeve is provided on the connecting sleeve to improve the convenience of installing and disassembling the shock absorber, and at the same time, the buffer mechanism and the friction mechanism are used to improve the shock absorption effect of the bracket in the axial direction of the shock absorber, when the shock absorber is working, usually the vehicle body presses the shock absorber obliquely downward, so when acting on the shock absorber, the shock absorber also presses the bracket obliquely downward, resulting in horizontal shear force and vertical extrusion force acting on each other between the shock absorber and the bracket. The shock absorber will be damaged under the action of the horizontal shear force for a long time, reducing the service life of the shock absorber.

[0006] 2. Since the above patent realizes the buffering of the axial movement of the shock absorber by the compression spring, during long-term use, due to the action of deformation and cyclic load, the spring may undergo fatigue damage, and finally the spring fails, and the stability of the buffering effect of the bracket needs to be improved. Summary of the Utility Model

[0007] In order to overcome the deficiencies of the prior art, the present utility model provides an automobile shock absorber bracket that is convenient for installation.

[0008] In order to achieve the above object, the present utility model provides the following technical solution: An automobile shock absorber bracket that is convenient for installation, including a base and a shock absorber. A bracket body is fixedly provided on the base. A buffer table is slidably connected inside the bracket body. A buffer device is arranged between the bottom of the buffer table and the bracket body.

[0010] Further, the side wall of the sliding groove is within the rotation range of the extrusion sphere. Two frustum-shaped grooves are formed on the inner wall of the bracket body. One end of the two frustum-shaped grooves away from the base is detachably connected with a limiting plate. The connecting slider is slidably connected in the frustum-shaped groove. One end of the frustum-shaped groove close to the base is always located above the bottom of the buffer table.

[0011] Further, the buffer device includes hydraulic buffer oil, an oil outlet pipe and a hydraulic valve. The hydraulic valve is connected to the bracket body through the oil outlet pipe in a communicating manner.

[0015] (1) By providing a connecting rod, an extrusion sphere, a buffer table and a frustum groove, when the shock absorber is subjected to an oblique pressure, the horizontal force is converted into a vertical pressure and acts on the buffer device of the bracket, reducing the horizontal extrusion force on the shock absorber and improving the durability and safety of the shock absorber bracket.

[0016] (2) By injecting hydraulic buffer oil between the bottom of the buffer table and the bracket body and controlling the inflow and outflow of the buffer oil through a hydraulic valve and a check valve, the bracket vertically linearly decelerates the shock absorber in a hydraulic manner. Compared with the buffer of a spring, the hydraulic buffer can provide a more uniform and stable buffer effect, helping the bracket to more smoothly control the movement of the shock absorber and improving the stability of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0025] Refer to Figure 1 andFigure 3 , Figure 4 , Figure 5 , Figure 6 , A vehicle shock absorber bracket that is convenient for installation, including a base 10 and a shock absorber 12. A bracket body 11 is fixedly connected to the base 10. A buffer table 24 is slidably connected inside the bracket body 11. A buffer device is arranged between the bottom of the buffer table 24 and the bracket body 11. Two frustum-shaped grooves 25 are formed on the inner wall of the bracket body 11. A limiting plate 26 is bolted to one end of the frustum-shaped groove 25 away from the base 10. Two disc brackets 22 are arranged inside the bracket body 11. The two disc brackets 22 are located above the buffer table 24. Two connecting sliders 27 are respectively fixedly arranged on the side walls of the two disc brackets 22. The two disc brackets 22 are bolted together through the connecting sliders 27. [[ID=⑧]] [[ID=⑨]]

[0026] [[ID=⑩]]The connecting slider 27 is slidably connected in the frustum-shaped groove 25. The disc bracket 22 realizes vertical sliding in the bracket body 11 through the connecting slider 27. Bearings spherical shells 31 are fixedly arranged at one ends of the two disc brackets 22 away from the bracket body 11. A bearing sphere 29 is movably connected inside the spherical support formed by splicing the two bearings spherical shells 31. The shock absorber 12 is fixedly connected to one side of the bearing sphere 29 away from the buffer table 24. A connecting rod 23 is fixedly connected to one side of the bearing sphere 29 close to the buffer table 24. One end of the connecting rod 23 close to the buffer table 24 is fixedly connected with an extrusion sphere 30. A sliding groove 28 is formed on the top surface of the buffer table 24 away from the base 10. The side wall of the sliding groove 28 is within the rotation range of the extrusion sphere 30. The extrusion sphere 30 can slide on the side wall of the sliding groove 28. [[ID=⑪]] [[ID=⑫]]

[0027] [[ID=⑬]]By the cooperation of the bearing sphere 29, the connecting rod 23, and the extrusion sphere 30, an extrusion force is applied to the side wall of the sliding groove 28, realizing that when the shock absorber 12 is subjected to an oblique pressure, the horizontal component force is converted into a vertical pressure and acts on the buffer device inside the bracket body 11, reducing the horizontal extrusion force between the shock absorber 12 and the bracket body 11 and reducing the wear of the shock absorber 12. [[ID=⑭]] [[ID=⑮]]

[0028] [[ID=⑯]]As[[ID=⑰]] Figure 1 [[ID=⑱]],[[ID=⑲]] Figure 2 [[ID=⑳]],[[ID=㉑]] Figure 3 [[ID=㉒]]shown, the buffer device includes hydraulic buffer oil, an oil outlet pipe 18, and a hydraulic valve 13; the hydraulic valve 13 is fixedly connected to the base 10. The hydraulic valve 13 and the bracket body 11 are connected through the oil outlet pipe 18. The hydraulic buffer oil is stored between the buffer table 24 and the bottom wall of the bracket body 11. The output end of the hydraulic valve 13 is connected with a first oil delivery pipe 19. One end of the first oil delivery pipe 19 away from the hydraulic valve 13 is connected with an oil storage tank 14. The oil storage tank 14 is fixedly connected to the base 10. The oil outlet of the oil storage tank 14 is connected with a second oil delivery pipe 20. [[ID=㉓]] [[ID=㉔]]

[0029] An oil pump bracket 16 is fixedly connected to the base 10. An oil pump 15 is installed on the oil pump bracket 16. The oil outlet end of the second oil pipeline 20 is connected to the oil pump 15 in a communicating manner. A third oil pipeline 21 is connected to the output end of the oil pump 15 in a communicating manner. One end of the third oil pipeline 21 far away from the oil pump 15 is fixedly connected with a check valve 17. The check valve 17 can prevent the hydraulic buffer oil from flowing out of the bracket body 11. The oil outlet end of the third oil pipeline 21 is connected to the bracket body 11 in a communicating manner.

[0030] Through the cooperation of the hydraulic valve 13, the oil storage tank 14, the oil pump 15 and the check valve 17, the inflow and outflow of the hydraulic buffer oil in the bracket body 11 can be controlled, realizing the vertical linear deceleration of the shock absorber by the bracket in a hydraulic way, which helps the bracket to control the movement of the shock absorber 12 more smoothly, reduces the wear of the shock absorber 12 when the bracket body 11 buffers it, and further improves the durability of the shock absorber 12.

[0031] In this embodiment, initially, the device is connected to the power supply and the oil pump 15 is started. The operator first injects a certain amount of hydraulic buffer oil into the bracket body 11, then slowly puts the buffer table 24 into the bracket body 11, and then installs the bearing sphere 29 fixed with the shock absorber 12 and the connecting rod 23 into the spherical shell of the bearing spherical shell 31.

[0032] Subsequently, the operator tightens the bolts in the connecting slider 27 to fix the two disc brackets 22. At this time, the bearing sphere 29 can only roll in the bearing spherical shell 31. The operator then aligns the connecting slider 27 with the circular table groove 25 and slides the disc bracket 22 fixed with the shock absorber 12 into the bracket body 11.

[0033] When the extrusion sphere 30 at the bottom of the connecting rod 23 abuts against the bottom of the sliding groove 28, the operator then installs the limiting plate 26 at the top of the circular table groove 25 and fixes the limiting plate 26 with bolts to prevent the connecting slider 27 from sliding out of the circular table groove 25 when the shock absorber 12 is vibrated. At this time, the installation of the shock absorber 12 and the bracket body 11 is completed.

[0034] When the vehicle is jolted and the vehicle body presses the shock absorber 12 vertically downward, the shock absorber 12 transmits the vertical pressure to the extrusion sphere 30 through the connecting rod 23. After the vertical sphere 30 receives the vertical pressure, it vertically extrudes the bottom wall of the sliding groove 28. After the bottom wall of 28 transmits the vertical extrusion force to the buffer table 24, the buffer table 24 will have a tendency to move downward and squeeze the hydraulic buffer oil.

[0035] When the vehicle body tilts and presses down on the shock absorber 12, after the shock absorber 12 receives the inclined pressure, it drives the bearing sphere 29 to roll. The rolling of the bearing sphere 29 causes the connecting rod 23 to tilt. The tilted connecting rod 23 drives the extrusion sphere 30 to slide onto the side wall of the sliding groove 28. After the extrusion sphere 30 slides a certain distance on the side wall of the sliding groove 28, it squeezes the sliding groove 28. The sliding groove 28 transmits the inclined pressure to the buffer platform 24. Then, the buffer platform 24 also has a tendency to move vertically downward and squeezes the hydraulic buffer oil in the bracket body 11.

[0036] When the hydraulic valve 13 detects that the oil pressure exceeds the preset value, it opens the valve. The hydraulic buffer oil flows from the first oil pipeline 19 into the oil storage tank 14. At this time, the hydraulic pressure at the hydraulic valve 13 gradually decreases. When the hydraulic pressure at the hydraulic valve 13 decreases to less than the preset value, the valve closes, and the hydraulic oil no longer flows out of the bracket body 11. The oil pump 15 pumps out the hydraulic oil flowing into the oil storage tank 14 and transports it to the check valve 17 through the third oil pipeline 21. After receiving the hydraulic oil flowing into the bracket body 11, the check valve 17 opens the valve, and the hydraulic oil flows back into the bracket body 11 again. At this time, the buffer platform 24 rises through the return flow of the hydraulic buffer oil, and the shock absorber 12 resets.

[0037] The above-mentioned hydraulic valve 13, oil pump 15, and check valve 17 are all mature existing technologies and will not be elaborated herein.
