Description

Technical Field

[0001] This invention belongs to the field of automotive damper technology, and specifically relates to an adjustable damper for automotive shock absorption. Background Technology

[0002] A damper is a device that provides resistance to motion and dissipates kinetic energy. Various types of dampers (or shock absorbers) have long been used in industries such as aerospace, aviation, military, firearms, and automobiles to reduce vibration and dissipate energy. With the development of technology, most existing automotive dampers are adjustable.

[0003] However, most existing adjustable dampers for automotive shock absorption have the following drawbacks:

[0004] 1. The springs are exposed to the outside, which makes it easy for stones kicked up by the wheels to get stuck between the springs when the car is driving on roads with a lot of stones. This can wear down the springs or even cause them to deform. However, most existing dampers cannot clear stones during use. Workers need to manually remove the stones from the springs, which is not only troublesome but also affects the normal use of the damper.

[0005] 2. Mud, water, dust and other contaminants easily adhere to the surface of the spring. After the mud and water dry, they remain on the surface of the spring and will have a certain impact on the use of the damper. However, the existing adjustable dampers do not have the function of cleaning the dried mud, dust and other contaminants in a timely manner.

Multiple round pins 35 are evenly slidably connected inside the guide frame 34. The multiple round pins 35 are arranged one-to-one with the multiple T-shaped blocks 31. The multiple round pins 35 are rotatably connected to the hinge point of the scissor structure 29 away from the T-shaped blocks 31.

[0042] The drive mechanism 4 includes an annular groove 41 inside the collar 21. A bevel gear ring 42 is rotatably connected inside the annular groove 41. The bottom ends of three fixed rods 27 extend into the annular groove 41 and are rotatably connected to the bevel gear ring 42.

[0043] A dust-proof ring 49 for sealing the three arc-shaped grooves 26 is provided between the three square shells 28 and the collar 21. The surface of the dust-proof ring 49 is evenly provided with circular grooves 50 that cooperate with the three fixed rods 27.

[0044] Each of the three square shells 28 has a spacing adjustment component 6 on one side for adaptively adjusting the position of multiple conical blocks 32;

[0045] The spacing adjustment assembly 6 includes an arc-shaped rod 61 fixedly connected to one side of the square shell 28 via a horizontal plate. A connecting plate 62 is movably sleeved on the outside of the arc-shaped rod 61. A rotating shaft 63 is fixedly connected to the end of the connecting plate 62 away from the main body 1. The rotating shaft 63 is rotatably connected inside the square shell 28. A first spring 64 is movably sleeved on the outside of the arc-shaped rod 61, and the first spring 64 is disposed between the horizontal plate and the connecting plate 62. A through slot 65 is opened on the side of the connecting plate 62 away from the main body 1. A scissor structure 29 is located at one end away from the main body 1. A guide rod 66 is fixedly connected at a hinge point. The surfaces of the square shell 28 and the connecting plate 62 are provided with slots 67 that cooperate with the guide rod 66. The end of the guide rod 66 away from the scissor structure 29 passes through the square shell 28 and extends into the interior of the connecting plate 62. A guide strip 68 is fixedly connected to the top end of the square shell 28 near the body 1. The cross-sectional shape of the guide strip 68 is T-shaped. A push plate 69 is slidably connected to the outside of the guide strip 68. The push plate 69 is located between the fixing rings 13 of the connecting plate 62.

[0046] The cone-shaped blocks 32 inside the three square frames are located in the gaps between every two turns of spring A14 in their original state;

[0047] When a car uses this adjustable damper on a complex road with many stones, the damper extends and retracts to cushion the impact. During this process, the piston rod 12 moves up and down inside the reservoir 11, causing the fixed ring 13 to move up and down synchronously. This causes the fixed ring 13 to drive the toothed plate 45 to reciprocate up and down inside the extension cover 43 via the L-shaped plate 48 and the round rod 47. When the toothed plate 45 moves down under the cooperation of the above structures, it drives the bevel gear 44 to rotate through the meshing action with the first gear 46. This causes the bevel gear 44 to drive the bevel gear 42 to rotate inside the collar 21 through the meshing action with the bevel gear ring 42. This, in turn, causes the three fixed rods 27 to rotate synchronously around the body 1 a certain distance through the bevel gear ring 42. At this time, the three fixed rods 27 rotate clockwise a certain distance inside the arc groove 26, causing the three fixed rods to rotate synchronously around the body 1. Rod 27 drives multiple conical blocks 32 to rotate synchronously around spring A14 via three square shells 28. At this time, the three square shells 28 drive three sliders 25 to slide synchronously inside the groove 24. The sliders 25 and the groove 24 cooperate with the fixed rod 27 and the arc groove 26 to ensure the stability of the movement trajectory of the three square shells 28. When spring A14 contracts, the multiple conical blocks 32 clear stones, mud, etc. stuck between spring A14. When the toothed plate 45 moves upward under the cooperation of the above structures, the toothed plate 45 drives the three square shells 28 to rotate counterclockwise to reset through the cooperation of the above structures. During the rotation, the three square shells 28 rotate in the opposite direction around spring A14 again by a certain angle. When spring A14 extends, the multiple conical blocks 32 clear stones, mud, etc. stuck between every two turns of spring A14.

[0048] During the extension and retraction of the spring A14, the telescopic tube 36 extends and retracts synchronously, always protecting the piston rod 12. This effectively prevents stones stuck between the spring A14 and the piston rod 12 from falling into the gap when the stone cleaning mechanism 2 cleans the stones stuck between the spring A14, ensuring the normal use of the damper. It also prevents stones kicked up by the wheels during driving from damaging the piston rod 12, effectively extending the overall service life of the damper.

[0049] While the aforementioned fixed rod 27 moves back and forth inside the arc groove 26, the three fixed rods 27 drive the dust-proof ring 49 to rotate synchronously around the body 1, thus keeping the arc groove 26 in a closed state, which can effectively prevent dust from entering the annular groove 41 from the arc groove 26 and affecting the normal use of the conical ring 42.

[0050] During the compression of the spring A14, the fixed ring 13 moves downward against the push plate 69 outside the guide bar 68, pushing the connecting plate 62 to rotate around the pivot 63. This causes the connecting plate 62 to slide outside the arc-shaped rod 61 and compress the first spring 64, so that the connecting plate 62 drives the guide rod 66 to move downward synchronously through the notch 67 on its surface. This, in turn, drives the scissor structure 29 to retract through the guide rod 66. At this time, multiple round pins 35 at one end of the scissor structure 29 slide closer to each other inside the guide frame 34, and synchronously push the guide frame 34 to slide away from the body 1 inside the two sliding grooves 33. The other end of the scissor structure 29 drives multiple T-shaped blocks 31 to slide inside the T-shaped groove 30. The T-blocks 31 move closer to each other, causing the cone blocks 32 to move closer synchronously, cooperating with the contraction of the spring A14, so that the cone blocks 32 are always located in the gap between every two turns of the spring A14, ensuring the cleaning effect of the cone blocks 32 on stones and other objects stuck between the springs A14; when the spring A14 extends, the fixing ring 13 releases its resistance to the multiple push plates 69. At this time, the connecting plate 62 pushes the push plates 69 upward and resets under the action of the first spring 64, and drives the scissor structure 29 to extend through the guide rod 66 and the cooperation between the above structures, so that the scissor structure 29 drives the cone blocks 32 to move away from each other through the T-blocks 31, so that the cone blocks 32 cooperate with the extended spring A14 again;

[0051] This invention, by incorporating a stone cleaning mechanism 2 and a driving mechanism 4, can promptly remove stones, mud, and other debris stuck between the springs A14 in the damper during use of the adjustable damper. This effectively prevents stones and mud from remaining stuck in the springs A14 for extended periods, thus avoiding severe wear or even deformation of the springs A14 during extension and retraction. This ensures the normal operation of the damper and extends the service life of the springs A14. Furthermore, the inclusion of a spacing adjustment component 6 ensures that the stone cleaning mechanism 2 always coordinates with the extension and retraction of the springs A14, effectively improving the performance of the stone cleaning mechanism 2.

[0052] like Figures 1-12 As shown, each of the three square shells 28 has an auxiliary mechanism 7 on the side away from the spacing adjustment component 6, which is used in conjunction with the stone cleaning mechanism 2.

[0053] The auxiliary mechanism 7 includes a protective cover 71 fixedly connected to the side of the square shell 28 away from the connecting plate 62. One end of the rotating shaft 63 extends into the interior of the protective cover 71 and is fixedly connected to a second gear 72. The interior of the protective cover 71 is rotatably connected to a third gear 73 that meshes with the second gear 72. The end of the axle of the third gear 73 away from the square shell 28 is fixedly connected to a disc 74. The bottom end of the protective cover 71 is slidably connected to a right-angle plate 75. The outer side of the disc 74 is uniformly fixedly connected to a protruding plate 76 for pushing the right-angle plate 75. The bottom end of the right-angle plate 75 is fixedly connected to a vertical plate 77. The side of the vertical plate 77 away from the main body 1 is fixedly connected to a second spring 78, and the side of the second spring 78 away from the vertical plate 77 abuts against the inner wall of the protective cover 71. The side of the right-angle plate 75 near the main body 1 is fixedly connected to a hammer plate 79 for striking the spring A14.

[0054] While the connecting plate 62 rotates around the pivot 63 via the interlocking structure, the connecting plate 62 drives the pivot 63 to rotate synchronously. This causes the pivot 63 to drive the second gear 72 to rotate. The meshing action between the second gear 72 and the third gear 73 drives the third gear 73 to rotate synchronously via the pivot 63. This causes the third gear 73 to drive the disc 74 to rotate synchronously via the pivot 63. Consequently, the convex plate 76 on the surface of the disc 74 drives the right-angle plate 75 to move. When one of the convex plates 76 rotates to the position where it contacts the right-angle plate 75, the convex plate 76 drives the right-angle plate 75 to move away from the main body 1, and the vertical plate 77 compresses the second spring 78. At this time, the right-angle plate 75 drives the hammer. The striking plate 79 moves away from the spring A14. When the convex plate 76 releases its resistance to the right-angle plate 75, the vertical plate 77, under the reset action of the second spring 78, pushes the right-angle plate 75 towards the spring A14 and hammers the spring A14, causing the spring A14 to vibrate. This process is repeated. While the stone cleaning mechanism 2 using the vertical plate 77 cleans the stones stuck between the springs A14, the three striking plates 79 continuously hammer the spring A14, causing the spring A14 to vibrate. This not only knocks off the dust and other debris attached to the surface of the spring A14, but also uses the vibration to work with the stone cleaning mechanism 2, making the stone cleaning more effortless.

[0055] By incorporating an auxiliary mechanism 7, this invention not only allows the dust adhering to the surface of the spring A14 to be shaken off during the use of the stone cleaning mechanism 2, but also loosens the stones stuck between the springs A14. This makes the stone cleaning mechanism 2 more labor-saving when cleaning stones, effectively preventing the phenomenon of difficulty in cleaning due to stones being stuck too tightly, and effectively improving the performance of the adjustable damper.

[0056] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
