An arc-shaped protrusion first passes through the arc portion of a first extrusion groove and then reaches the interior of a second extrusion groove again, thereby enabling the arc-shaped protrusion to be stuck into the interior of the second extrusion groove. Since the groove depth of the second extrusion groove is less than that of the first extrusion groove, the fixation between the inner steel column and the first rubber ring is more secure. The worn end of the first rubber ring continues to press against the swing arm under the pressure of the pressure column, thereby extending the service life of the device.

Description

Technical Field

[0001] The present invention relates to the field of automobile accessories, and more particularly to a rubber shock-absorbing bushing for an automobile frame. Background Art

[0002] Bushings, which include conventional rubber bushings and hydraulic rubber bushings, are rubber components used in automotive chassis and serve as hinge points between various vehicle body components. Their superior elasticity and damping properties allow them to withstand loads, isolate and damp vibrations, reduce noise, and ensure ride comfort, significantly impacting vehicle suspension design. Bushings vary in type, driven both by their installation locations and loads, and by their ability to meet performance requirements, such as dynamic and static stiffness, and durability.

[0003] Automobile frame rubber shock-absorbing bushings generally consist of three parts: a metal outer shell, an intermediate rubber body, and an inner tube. These three parts are connected together to form a complete bushing. The existing method is to directly connect the metal outer shell and the inner tube through the intermediate rubber body. This will cause the inner tube to axially dislodge during use, causing shock damage.

[0004] A Chinese patent with authorization announcement number CN212584170U discloses a rubber shock-absorbing bushing for an automobile frame. The rubber shock-absorbing bushing has an external structure formed by a top cover, a bottom cover and a metal shell. The top cover, the bottom cover and the metal shell are fixed by fixing nuts and washers. A spring is set on the inner tube to fix the inner tube in combination with a fixing ring. The fixing ring is used to connect the inner tube to the slide groove and the slider through a connecting column. When the shock-absorbing bushing is subjected to vibration, the inner tube can be buffered without being separated from the metal shell.

[0005] Although the above patent uses a fixing ring to cooperate with the connecting column to connect the slide groove and the slider, which can buffer the inner tube without separating from the metal shell when the shock-absorbing bushing is vibrated, long-term friction between the bushing and the swing arm can easily cause a gap between the bushing and the swing arm, resulting in poor fixing effect between the two. Summary of the Invention

[0006] In response to the problems existing in the prior art, the purpose of the present invention is to provide a rubber shock-absorbing bushing for an automobile frame, in which an arc-shaped protrusion first passes through the arc-shaped part of a first extrusion groove, and then reaches the interior of a second extrusion groove again, so that the arc-shaped protrusion is stuck in the interior of the second extrusion groove. Since the groove depth of the second extrusion groove is smaller than the groove depth of the first extrusion groove, the fixation between the inner steel column and the first rubber ring is more firmly made, and the worn end of the first rubber ring continues to squeeze the swing arm under the extrusion of the pressure column, so that the device can be used for a longer time.

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] A rubber shock-absorbing bushing for an automobile frame, comprising a lower fixed plate, the top of the lower fixed plate being fixedly connected to an inner steel column, the bottom of the outer surface of the inner steel column being fixedly connected to a second rubber ring, the top of the second rubber ring being provided with a first rubber ring fixedly connected to the inner steel column, and the top of the first rubber ring being provided with an upper fixed plate fixedly connected to the lower fixed plate via the inner steel column;

[0009] An inner steel column, which is placed inside the first rubber ring and squeezes the first rubber ring through rotation of the inner steel column, so that the first rubber ring is always fixed to the swing arm and the first rubber ring is always squeezed toward the swing arm. When the first rubber ring and the swing arm are worn for a long time, the first rubber ring is squeezed by the inner steel column and fits the swing arm again;

[0010] The inner steel column includes a plurality of first extrusion grooves formed in an annular array on the outer surface of the inner steel column. The cross section of the first extrusion groove is a figure formed by connecting an arc and a quarter circle. A second extrusion groove is formed between each of the plurality of first extrusion grooves. The second extrusion groove has the same diameter as the quarter circle portion of the first extrusion groove.

[0011] a first rubber ring, the first rubber ring being used for fixing to the swing arm;

[0012] The first rubber ring includes a plurality of arc-shaped protrusions distributed in an annular array and extending along the inner wall of the first rubber ring toward the center of the first rubber ring. The plurality of arc-shaped protrusions are all snapped into the corresponding quarter-circle parts of the first extrusion groove. A plurality of pressurizing columns distributed in an annular array are fixedly connected to the positions of the arc-shaped protrusions inside the first rubber ring.

[0013] Furthermore, a fixing mechanism is provided between the upper fixing plate and the lower fixing plate, and the fixing mechanism includes a threaded rod rotatably connected to the interior of the upper fixing plate, and the bottom of the threaded rod passes through the upper fixing plate and extends to the inner bottom end of the inner steel column.

[0014] Furthermore, a threaded barrel is fixedly connected to the interior of the lower fixed plate, and the top of the threaded barrel passes through the lower fixed plate and extends to the inner top end of the inner steel column.

[0015] Furthermore, the threaded rod is connected to the threaded barrel via threads, the bottom of the threaded barrel is rotatably connected to a rotating block, the bottom of the threaded rod is fixedly connected to a fixed block, and the rotating block is movably connected to the fixed block.

[0016] Furthermore, the top of the rotating block extends upward to form a limiting cylinder, the limiting cylinder is fitted with the fixed block, and the limiting cylinder extends toward the fixed block to form a second sliding block.

[0017] Furthermore, a moving groove is provided inside the fixed block at a position corresponding to the second slider, and an annular groove is provided on the outer surface of the fixed block corresponding to the up and down moving track of the second slider.

[0018] Furthermore, the outer surface of the rotating block extends in the direction of the threaded barrel to form a first sliding block, and the interior of the threaded barrel is provided with an arc groove corresponding to the rotation track of the first sliding block.

[0019] Furthermore, a spring is fixedly connected to the interior of the arc-shaped groove, and the spring is welded to the first slider. When the first slider does not move, the spring is in a naturally extended state.

[0020] Furthermore, the interior of the threaded barrel extends along the direction of the arc groove to form an arc block, and one end of the arc block close to the first slider penetrates the first slider and is fixedly connected to a limiting block.

[0021] Furthermore, the limiting block is made of rubber, and the cross-section of the limiting block is an isosceles trapezoid.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In this solution, the arc-shaped protrusion first passes through the arc-shaped portion of the first extrusion groove, and then reaches the interior of the second extrusion groove again, so that the arc-shaped protrusion is stuck in the interior of the second extrusion groove. Since the groove depth of the second extrusion groove is smaller than the groove depth of the first extrusion groove, the fixation between the inner steel column and the first rubber ring is more firmly established. The worn end of the first rubber ring continues to press against the swing arm under the pressure of the pressure column, thereby extending the service life of the device. Under the pressure of the upper fixing plate and the lower fixing plate on the swing arm, the first rubber ring and the second rubber ring are effectively prevented from detaching from the swing arm, and the fixation between the swing arm and the vehicle body is further reinforced, making the fixation more secure.

[0024] 2. This solution inserts the lower fixing plate with the inner steel column into the second rubber ring and the first rubber ring, making it easy for the arc-shaped protrusion to fit into the quarter-circle part of the first extrusion groove, facilitating the insertion of the inner steel column and positioning the inner steel column for subsequent fixation, making the device and the swing arm more firmly fixed.

[0025] 3. This solution is to align the inner steel column with the upper fixed plate and the lower fixed plate after the inner steel column is rotated, insert the threaded barrel into the lower fixed plate and the inner steel column, and then insert and rotate the threaded rod into the upper fixed plate and the inner steel column. The threaded rod gradually extends into the threaded barrel to fix the upper fixed plate, the lower fixed plate and the inner steel column, thereby fixing the device to the swing arm.

[0026] 4. In this solution, the rotating block moves the first slider inside the arc groove, and squeezes the spring during the movement, causing the spring to change from a naturally stretched state to a tense state. After the second slider passes through the annular groove and reaches the inside of the moving groove, the rotating block is released, and the rotating block returns to its original position under the elasticity of the spring.

[0027] 5. In this solution, the rotating block rotates with the second slider to rotate inside the movable groove. The groove wall of the movable groove is located below the rotated second slider, thereby achieving misalignment between the second slider and the annular groove, and further reinforcement of the threaded rod and the threaded barrel. The second slider is inside the movable groove. When the device vibrates, the second slider will not move under the action of the spring, so that the rotating block will not move, effectively preventing the threaded rod and the threaded barrel from being separated due to vehicle vibration, and achieving better shockproof effect.

[0028] 6. In this solution, a limiting block is fixedly connected to the end of the arc block, and the rotating threaded barrel can only be moved by the first slider being squeezed to deform the limiting block. In other cases, the shape of the limiting block is restricted, making the rotation of the threaded barrel more difficult, thereby preventing the threaded barrel from rotating due to vibration.

[0040] 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; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] Example 1:

[0042] See also Figures 1 to 4 , a rubber shock-absorbing bushing for an automobile frame includes a lower fixed plate 4, the top of the lower fixed plate 4 is fixedly connected to an inner steel column 41, the bottom of the outer surface of the inner steel column 41 is fixedly connected to a second rubber ring 3, the top of the second rubber ring 3 is provided with a first rubber ring 2 fixedly connected to the inner steel column 41, the top of the first rubber ring 2 is provided with an upper fixed plate 1 fixedly connected to the lower fixed plate 4 through the inner steel column 41; the inner steel column 41, the inner steel column 41 is used to be placed inside the first rubber ring 2, and the first rubber ring 2 is squeezed by the rotation of the inner steel column 41, so that the first rubber ring 2 is always fixed to the swing arm, and the first rubber ring 2 is always squeezed toward the swing arm. When the first rubber ring 2 and the swing arm are worn for a long time, the first rubber ring 2 is fit to the swing arm again under the squeezing of the inner steel column 41; the inner steel column 41 contains The inner steel column 41 includes a plurality of first extrusion grooves 42 formed in an annular array on the outer surface thereof. The cross-section of the first extrusion grooves 42 is a pattern formed by connecting an arc and a quarter circle. A second extrusion groove 43 is formed between each of the plurality of first extrusion grooves 42. The second extrusion grooves 43 have the same diameter as the quarter circle portion of the first extrusion groove 42. A first rubber ring 2 is provided, and the first rubber ring 2 is used to be fixed to the swing arm. The first rubber ring 2 includes a plurality of arc-shaped protrusions 22 distributed in an annular array and extending along the inner wall of the first rubber ring 2 toward the center of the first rubber ring 2. The plurality of arc-shaped protrusions 22 are each snapped into the corresponding quarter circle portion of the first extrusion groove 42. A plurality of pressurizing columns 21 distributed in an annular array are fixedly connected to the interior of the first rubber ring 2 at positions corresponding to the arc-shaped protrusions 22.

[0043] By placing the first rubber ring 2 and the second rubber ring 3 directly in the swing arm hole, it is more convenient to place the first rubber ring 2 and the second rubber ring 3 in the swing arm. Then, the lower fixing plate 4 is inserted into the second rubber ring 3 and the first rubber ring 2 with the inner steel column 41, so that the arc-shaped protrusion 22 is conveniently inserted into the quarter-circle part of the first extrusion groove 42, which is convenient for inserting the inner steel column 41 and positioning the inner steel column 41 to facilitate subsequent fixation, so that the device and the swing arm are fixed more firmly. Then, the lower fixing plate 4 is rotated, and the rotation of the lower fixing plate 4 causes the inner steel column 41 to rotate, and the rotation of the inner steel column 41 causes the first extrusion groove 42 and the second extrusion groove 43 to rotate, and the arc-shaped protrusion 22 first passes through the arc part of the first extrusion groove 42, and then the arc-shaped protrusion 22 reaches the inside of the second extrusion groove 43 again, so that the arc-shaped protrusion 22 is inserted into the inside of the second extrusion groove 43. Since the groove depth of the second extrusion groove 43 is less than the groove depth of the first extrusion groove 42, the inner steel column 41 is The fixation between the first rubber ring 2 and the first rubber ring 2 is more firm, and the second extrusion groove 43 squeezes the arc-shaped protrusion 22. An inner steel column 41 is installed at the position of the arc-shaped protrusion 22. The arc-shaped protrusion 22 is deformed by the extrusion of the inner steel column 41. The deformation of the arc-shaped protrusion 22 squeezes the pressure column 21. The pressure column 21 is squeezed and moves. The pressure column 21 moves toward the outer surface of the first rubber ring 2, so that the fixation between the outer surface of the first rubber ring 2 and the swing arm is more firm, and the pressure column 21 is always in the state of squeezing the first rubber ring 2. The outer surface of the first rubber ring 2 is always in the state of squeezing the swing arm. When the first rubber ring 2 is worn, the worn end of the first rubber ring 2 continues to squeeze the swing arm under the squeezing of the pressure column 21, so that the service life of the device is longer. Under the squeezing of the swing arm by the upper fixing plate 1 and the lower fixing plate 4, the first rubber ring 2 and the second rubber ring 3 are effectively prevented from detaching from the swing arm, and the fixation between the swing arm and the vehicle body is continued to be reinforced, making the fixation more firm.

[0044] like Figure 5 As shown, a fixing mechanism 5 is provided between the upper fixing plate 1 and the lower fixing plate 4, and the fixing mechanism 5 includes a threaded rod 51 rotatably connected to the interior of the upper fixing plate 1, the bottom of the threaded rod 51 passes through the upper fixing plate 1 and extends to the inner bottom end of the inner steel column 41, and the interior of the lower fixing plate 4 is fixedly connected with a threaded barrel 52, the top of the threaded barrel 52 passes through the lower fixing plate 4 and extends to the inner top end of the inner steel column 41.

[0045] Insert the inner steel column 41 and the first rubber ring 2 and the second rubber ring 3 into the swing arm hole. After the inner steel column 41 is rotated, the inner steel column 41 is aligned with the upper fixed plate 1 and the lower fixed plate 4. Insert the threaded barrel 52 into the lower fixed plate 4 and the inner steel column 41. Then insert and rotate the threaded rod 51 into the upper fixed plate 1 and the inner steel column 41. The threaded rod 51 gradually extends into the threaded barrel 52, so that the upper fixed plate 1, the lower fixed plate 4 and the inner steel column 41 are fixed, thereby achieving fixation between the device and the swing arm.

[0046] like Figures 5 to 9 As shown, the threaded rod 51 is connected to the threaded cylinder 52 by threads, and the bottom of the threaded cylinder 52 is rotatably connected to a rotating block 53, and the bottom of the threaded rod 51 is fixedly connected to a fixed block 54. The rotating block 53 is movably connected to the fixed block 54, and the top of the rotating block 53 extends upward to form a limiting cylinder 533, and the limiting cylinder 533 fits with the fixed block 54. The limiting cylinder 533 extends toward the fixed block 54 to form a second slider 532. The interior of the fixed block 54 is provided with a moving groove 541 corresponding to the position of the second slider 532, and the outer surface of the fixed block 54 is provided with an annular groove 542 corresponding to the up and down movement trajectory of the second slider 532. The outer surface extends in the direction of the threaded barrel 52 to form a first slider 531. The interior of the threaded barrel 52 is provided with an arc groove 521 corresponding to the rotation trajectory of the first slider 531. The interior of the arc groove 521 is fixedly connected to a spring 55, and the spring 55 is welded to the first slider 531. When the first slider 531 does not move, the spring 55 is in a naturally extended state. The interior of the threaded barrel 52 extends along the direction of the arc groove 521 to form an arc block 522. The end of the arc block 522 close to the first slider 531 passes through the first slider 531 and is fixedly connected to a limiting block 523. The material of the limiting block 523 is rubber, and the cross-sectional shape of the limiting block 523 is an isosceles trapezoid.

[0047] By rotating the rotating block 53, the rotating block 53 rotates with the limiting cylinder 533 and the second slider 532. After rotation, the second slider 532 is aligned with the annular groove 542 in the fixed block 54. During the rotation of the rotating block 53, the rotating block 53 moves with the first slider 531 inside the arc groove 521, and squeezes the spring 55 during the movement. The spring 55 changes from a naturally stretched state to a tight state. The second slider 532 passes through the annular groove 542 and reaches the inside of the moving groove 541, and then releases the rotating block 53. The rotating block 53 returns to its original position under the elasticity of the spring 55. The rotating block 53 rotates with the second slider 532 inside the moving groove 541. The groove wall of the moving groove 541 is below the rotated second slider 532, so that the second slider 532 is aligned with the annular groove 54 2, the threaded rod 51 and the threaded barrel 52 are further reinforced, and the second slider 532 is inside the moving groove 541. When the device vibrates, the second slider 532 will not move under the action of the spring 55, so that the rotating block 53 will not move, effectively preventing the threaded rod 51 and the threaded barrel 52 from being separated due to the vibration of the car, so as to achieve better shockproof effect. The arc block 522 extends into the interior of the first slider 531, and the end of the arc block 522 is fixedly connected to the limiting block 523. The rotating threaded barrel 52 can only move by the squeezing of the first slider 531 to deform the limiting block 523. In other cases, the shape of the limiting block 523 restricts the threaded barrel 52, making it more difficult to rotate, thereby preventing the threaded barrel 52 from rotating due to vibration.

[0048] Usage: Place the first rubber ring 2 and the second rubber ring 3 directly in the swing arm hole, rotate the lower fixed plate 4, and the arc-shaped protrusion 22 is stuck in the second extrusion groove 43. The second extrusion groove 43 squeezes the arc-shaped protrusion 22. The arc-shaped protrusion 22 is squeezed by the inner steel column 41 and deforms and squeezes the pressure column 21. The threaded cylinder 52 is inserted into the lower fixed plate 4 and the inner steel column 41, and then the threaded rod 51 is inserted and rotated into the upper fixed plate 1 and the inner steel column 41. The threaded rod 51 gradually extends into the threaded cylinder 52, so that the upper fixed plate 1, the lower fixed plate 4 and the inner steel column 4 1, rotate the rotating block 53, the second slider 532 is aligned with the annular groove 542 in the fixed block 54, and the rotating block 53 rotates with the second slider 532 to rotate inside the movable groove 541. The lower part of the rotated second slider 532 is the groove wall of the movable groove 541. The second slider 532 is misaligned with the annular groove 542, and the arc block 522 extends into the interior of the first slider 531. The end of the arc block 522 is fixedly connected to the limiting block 523, and the rotating threaded cylinder 52 can only be squeezed by the first slider 531, so that the limiting block 523 is deformed.

Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
