Description

Technical Field

[0001] The utility model relates to the technical field of shock absorber upper supports, in particular to an automobile front shock absorber upper support. Background Art

[0002] As the guiding and force-transmitting element of the automobile suspension system, the shock absorber transmits various forces acting on the wheels to the vehicle body, while ensuring that the wheels move along a certain trajectory. The connection structure between the shock absorber upper support and the vehicle body is difficult to effectively cushion the vibration, which can easily cause the shock absorber upper support to be over-strained after a period of use, and make it difficult for the shock absorber upper support to achieve the expected service life.

[0003] Prior art patent publication number CN213298699U discloses an automobile shock absorber upper support that effectively guarantees service life. The patent utilizes a shock-absorbing block with a deformable cavity that absorbs vibration force through its own compression deformation, thereby slowing the transmission of vibration force between the vehicle body and the mounting portion. This reduces excessive wear on the shock absorber upper support caused by vibration force, ensuring that the shock absorber upper support reaches its intended service life.

[0004] However, the shock-absorbing block is a rubber block with a flexible texture and a large static friction coefficient on the outer surface. The shock-absorbing block made of rubber is very easy to harden after long-term use, so the shock-absorbing block needs to be replaced regularly. However, the positioning sleeve that carries the shock-absorbing block in the above-mentioned patent is fixedly installed in the settlement groove on the mounting part through the positioning assembly, and the mounting part is mounted on the vehicle body through fixing screws. Therefore, it is necessary to manually remove the mounting part from the vehicle body each time, and then remove the positioning sleeve from the settlement groove to finally realize the removal of the shock-absorbing block. The actual operation is time-consuming and labor-intensive, and the work efficiency is poor. Utility Model Content

[0005] In order to solve the above technical problems, an upper support for a front shock absorber of an automobile is provided, which solves the problem in the prior art that it is inconvenient to remove and replace the shock-absorbing block on the upper support for the shock absorber.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an upper support for a front shock absorber of an automobile comprises an upper support body of the shock absorber, a contraction groove provided on the top surface of the upper support body of the shock absorber, and a shock absorbing component provided in the contraction groove, wherein the shock absorbing component comprises a positioning sleeve slidably provided in the contraction groove and a shock absorbing block fixed inside the positioning sleeve, a lifting component is provided below the positioning sleeve, a draw-out opening communicating with the inner cavity of the contraction groove is provided on the side wall of the upper support body of the shock absorber, and the diameter of the draw-out opening is adapted to the size of the shock absorbing component;

[0007] The lifting component includes a bearing plate detachably arranged on the bottom surface of the positioning sleeve and a pulley installed on the bottom surface of the bearing plate. An extrusion component for affecting the lifting movement of the pulley is arranged on the side of the pulley.

[0008] Preferably, the extrusion assembly includes an extrusion block that is slidably arranged in a triangular shape on the inner wall of the bottom end of the contraction groove, the wheel body of the pulley is in contact with the oblique side of the extrusion block, and an internal threaded barrel is rotatably arranged in the inner side wall of the upper support body of the shock absorber, and a threaded push-pull rod is threadedly connected to the inner side of the internal threaded barrel, and the threaded push-pull rod penetrates into the contraction groove and is fixedly connected to one side of the extrusion block.

[0009] Preferably, two slide bars are symmetrically fixed on the inner wall of the bottom end of the shrinkage groove, and a notch adapted to the slide bars is provided on the bottom surface of the extrusion block.

[0010] Preferably, two T-shaped inserting strips are symmetrically fixed on the top surface of the carrier plate, and a T-shaped slot adapted to the T-shaped inserting strips is provided on the bottom surface of the positioning sleeve.

[0011] Preferably, one end of the internal threaded barrel away from the extrusion block is rotated to pass through the upper support body of the shock absorber and is tightly sleeved with an anti-slip sleeve.

[0012] Preferably, a picking groove is provided on a side wall of the positioning sleeve facing the drawing opening.

[0013] Compared with the prior art, the advantages of the present invention are: through the setting of the lifting component, when the shock-absorbing block needs to be replaced after long-term use, it is only necessary to use the lifting component to cause the positioning sleeve to sink inside the shrinkage groove, so that the shock-absorbing block shrinks inside the shrinkage groove and separates from the vehicle body, until the shock-absorbing component composed of the positioning sleeve and the shock-absorbing block moves to a position corresponding to the pull-out opening. In this way, the shock-absorbing component can be easily pulled out and replaced through the pull-out opening, without the need for manual disassembly and assembly of the support body on the shock absorber, thereby effectively improving manual work efficiency and enhancing practicality.

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0020] Reference Figure 1-3 As shown, the upper support of the front shock absorber of the automobile includes a shock absorber upper support body 1, a contraction groove 2 provided on the top surface of the shock absorber upper support body 1, and a shock absorbing component arranged in the contraction groove 2. The shock absorbing component includes a positioning sleeve 3 slidably arranged in the contraction groove 2 and a shock absorbing block 4 fixed inside the positioning sleeve 3.

[0021] When the shock absorber upper support body 1 is fixedly installed on the vehicle body using fixing bolts, the shock-absorbing block 4 can be in close contact with the vehicle body, and then through the compression deformation of the shock-absorbing block 4, the vibration force transmitted between the vehicle body and the shock absorber upper support body 1 is absorbed, thereby reducing the strain intensity of the shock absorber upper support body 1 and ensuring that the shock absorber upper support body 1 reaches the expected service life.

[0022] Further, refer to Figure 2 and Figure 3 As shown, it is worth noting that a lifting component is provided below the positioning sleeve 3, and a drawing port 12 communicating with the inner cavity of the shrinkage groove 2 is provided on the side wall of the upper support body 1 of the shock absorber, and the diameter of the drawing port 12 is adapted to the size of the shock absorbing component;

[0023] By setting the lifting component, when the shock-absorbing block 4 needs to be replaced after long-term use, it is only necessary to use the lifting component to cause the positioning sleeve 3 to sink inside the shrinkage groove 2, so that the shock-absorbing block 4 shrinks inside the shrinkage groove 2 and separates from the vehicle body, until the shock-absorbing component composed of the positioning sleeve 3 and the shock-absorbing block 4 moves to the position corresponding to the pull-out opening 12, so that the shock-absorbing component can be easily pulled out and replaced through the pull-out opening 12, without the need for manual disassembly and assembly of the shock absorber upper support body 1, thereby effectively improving manual work efficiency and enhancing practicality.

[0024] Further, refer to Figure 3 As shown, it is worth noting that the lifting component includes a bearing plate 5 detachably arranged on the bottom surface of the positioning sleeve 3 and a pulley 6 installed on the bottom surface of the bearing plate 5, and an extrusion component for causing the pulley 6 to lift and lower is provided on the side of the pulley 6;

[0025] The extrusion assembly includes an extrusion block 7 that is slidably arranged in a triangular shape on the inner wall of the bottom end of the contraction groove 2. The wheel body of the pulley 6 is in contact with the oblique side of the extrusion block 7. An internal threaded barrel 8 is rotatably arranged in the inner side wall of the upper support body 1 of the shock absorber. A threaded push-pull rod 9 is threadedly connected to the inner side of the internal threaded barrel 8. The threaded push-pull rod 9 penetrates into the contraction groove 2 and is fixedly connected to one side of the extrusion block 7.

[0026] The end of the internal threaded tube 8 away from the extrusion block 7 rotates to pass through the upper support body 1 of the shock absorber and is tightly sleeved with an anti-slip sleeve 10;

[0027] The knob anti-slip sleeve 10 causes the internal threaded tube 8 to rotate, and the threaded push-pull rod 9 can gradually shrink toward the inside of the internal threaded tube 8 under the threaded structure and stretch the extrusion block 7 to slide, causing the extrusion block 7 to reduce the extrusion on the pulley 6. The pulley 6 and the supporting plate 5 as a whole can actively sink to the inside of the contraction groove 2 under their own weight, so that the shock-absorbing component composed of the positioning sleeve 3 and the shock-absorbing block 4 as a whole shrinks to the inside of the contraction groove 2, which is convenient for disassembly and replacement.

[0028] Further, refer to Figure 3 As shown, it is worth noting that two slide bars 11 are symmetrically fixed on the inner wall of the bottom end of the shrinkage groove 2, and a notch adapted to the slide bar 11 is opened on the bottom surface of the extrusion block 7;

[0029] Through the setting of the slide bar 11 and the notch, when the threaded push-pull rod 9 pushes and pulls the extrusion block 7, the extrusion block 7 can slide synchronously on the slide bar 11, and then the slide bar 11 is used to limit the moving trajectory of the extrusion block 7, ensuring the stability of the extrusion block 7 during movement.

[0030] Further, refer to Figure 3 As shown, it is worth noting that two T-shaped inserts 13 are symmetrically fixed on the top surface of the carrier plate 5, and a T-shaped slot adapted to the T-shaped inserts 13 is provided on the bottom surface of the positioning sleeve 3;

[0031] Through the arrangement of the slot and the T-shaped inserting strip 13, when the positioning sleeve 3 is pulled out through the draw-out opening 12, the positioning sleeve 3 can slide along the T-shaped inserting strip 13 toward the inner side of the draw-out opening 12, thereby limiting the movement trajectory of the positioning sleeve 3, so that the positioning sleeve 3 can be pulled out smoothly, and when the positioning sleeve 3 is slid onto the carrier plate 5, the T-shaped inserting strip 13 slides into the T-shaped slot, and the T-shaped inserting strip 13 matches the shape of the T-shaped slot, which can effectively stabilize the positioning sleeve 3.

[0032] Further, refer to Figure 3 As shown, it is worth noting that a pick-out groove 14 is provided on one side wall of the positioning sleeve 3 facing the draw-out opening 12;

[0033] The provision of the picking groove 14 makes it easy for a human finger to pick into the inner side thereof, thereby utilizing the pulling and drawing operation of the positioning sleeve 3 .

[0034] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
