Description

Technical Field

[0001] The utility model relates to a hoop connection structure, in particular to a hoop connection structure of an automobile shock absorber cylinder. Background Art

[0002] An automobile shock absorber cylinder is a device used to suppress the oscillation when the automobile spring rebounds after absorbing shock and the impact from the road surface. It is widely used in the field of automobiles, and its main purpose is to accelerate the attenuation of the vibration of the vehicle frame and the body, so as to improve the ride comfort of the automobile.

[0003] The hoop connection of the vehicle shock absorber cylinder is an important part of the vehicle suspension system. Its main function is to improve the stability of the vehicle by fixing the positions of the suspension and the wheels. This connection method can effectively reduce the impact from the road surface, enabling the vehicle to maintain a certain stability during driving and improving the driving comfort at the same time. In addition, the hoop connection of the shock absorber cylinder can also protect the shock absorber and extend its service life, because its buffering effect can reduce the impact and protect the shock absorber from damage, thus ensuring the safety and reliability of the vehicle. The common hoop connection is through bolt connection.

[0004] When using bolt connection for the hoop, the bolt holes on the hoop need to be aligned, otherwise the bolt cannot be inserted into the bolt holes, resulting in the inability to connect the hoop; and before the hoop fixes the shock absorber cylinder, a certain tightening distance needs to be reserved between the bolt holes. During the bolt connection process, the tightening distance continuously shrinks, so that the hoop can stably clamp the shock absorber cylinder; this tightening distance increases the difficulty of aligning the bolt holes, making the hoop connection more difficult. Content of the Utility Model

[0005] The purpose of the utility model is to provide a hoop connection structure of an automobile shock absorber cylinder to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

An internally threaded slider is connected to each adjusting mechanism, and the adjusting mechanism can drive the internally threaded slider to move away from or close to the arc-shaped hoop;

[0008] A docking component is rotatably arranged on one internally threaded slider, and a limiting component is rotatably arranged on the other internally threaded slider; the two internally threaded sliders can be connected together through the mutual cooperation of the docking component and the limiting component.

[0011] The hoop connection structure of the vehicle shock absorber cylinder as described above: The limiting assembly includes a connection sleeve rotatably installed on the other internal-threaded slider, and a clamping groove is formed on the connection sleeve.

[0012] The hoop connection structure of the vehicle shock absorber cylinder as described above: The surface of the arc-shaped convex platform close to the hinge platform is set as an inclined surface that shrinks away from the hinge platform; the surface of the clamping groove away from the internal-threaded slider is set as a slope extending towards the internal-threaded slider, and the inclined surface and the slope can be clamped with each other.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] Please refer to Figures 1 to 7 , as an embodiment of the present invention, the hoop connection structure of the automobile shock absorber cylinder includes an adjustment mechanism installed at both ends of the arc-shaped hoop 1, and an internal thread slider 4 is connected to each adjustment mechanism. The adjustment mechanism can drive the internal thread slider 4 to move away from or close to the arc-shaped hoop 1;

[0032] A docking component is rotatably arranged on one internal thread slider 4, and a limiting component is rotatably arranged on the other internal thread slider 4; the two internal thread sliders 4 can be connected together through the mutual cooperation of the docking component and the limiting component.

[0033] In this embodiment, the arc-shaped hoop 1 is composed of two hinged arc-shaped clamping members. When fixing the vehicle shock absorber cylinder, one arc-shaped clamping member is installed on the vehicle suspension, and then the other arc-shaped clamping member is rotated to surround the shock absorber cylinder.

[0034] During the rotation of the arc-shaped clamping member, the docking assembly will cooperate with the limiting assembly to stably connect the two internal thread sliders 4 together. Among them, the docking assembly can connect the two internal thread sliders 4 together, and the limiting assembly will limit the displacement of the docking assembly to prevent the two internal thread sliders 4 from disconnecting, resulting in the shock absorber cylinder losing its shock absorption function.

[0035] After the limiting assembly and the docking assembly cooperate with each other, the adjusting mechanism drives the internal thread slider 4 connected thereto to move away from or close to the arc-shaped hoop 1. During the process of moving away from or close to, the included angle between the limiting assembly and the internal thread slider 4 and the included angle between the docking assembly and the internal thread slider 4 will change. In this way, the clamping force of the arc-shaped hoop 1 on the shock absorber cylinder is increased, thereby improving the fixing ability of the arc-shaped hoop 1 on the shock absorber cylinder and avoiding the displacement of the shock absorber cylinder caused by factors such as vibration during vehicle driving, which reduces the shock absorption effect.

[0036] Through the mutual cooperation of the adjusting structure with the docking assembly and the limiting assembly, the applicable range of the arc-shaped hoop 1 can be improved, and the arc-shaped hoop 1 can stably provide a clamping force for the shock absorber cylinder to prevent the shock absorber cylinder from being misaligned. And because the arc-shaped hoop is first connected by the cooperation of the docking assembly and the limiting assembly, and then the clamping force of the arc-shaped hoop on the shock absorber cylinder is adjusted by the adjusting mechanism, the installation is relatively simple and convenient.

[0037] As a further solution of the present invention, the adjusting mechanism includes a connecting block 2 installed on the arc-shaped hoop 1. A sliding groove 201 that is slidably matched with the internal thread slider 4 is formed on the connecting block 2. A lead screw column 3 is rotatably installed in the sliding groove 201, and the lead screw column 3 is threadedly connected to the internal thread slider 4.

[0038] In this embodiment, the lead screw column 3 is rotated, and the internal thread slider 4 is driven to slide in the sliding groove 201 through the threaded cooperation with the internal thread slider 4 to move away from or close to the arc-shaped hoop 1.

[0039] After the docking component and the limiting component cooperate with each other, if the clamping force of the arc-shaped clamp 1 on the shock-absorbing cylinder is insufficient, first, rotate a lead screw column 3 to drive the internally threaded slider 4 connected thereto to slide in the chute 201 and approach the arc-shaped clamp 1, thereby pulling the other internally threaded slider 4 through the docking component and the limiting component to reduce the distance between the two internally threaded sliders 4, so as to increase the clamping force of the arc-shaped clamp 1 on the shock-absorbing cylinder. When the lead screw column 3 that rotates drives the internally threaded slider 4 connected thereto to slide to the end of the chute 201 and the clamping force of the arc-shaped clamp 1 on the shock-absorbing cylinder is still insufficient, at this time, rotate the other lead screw column 3 to drive the internally threaded slider 4 connected thereto to approach the arc-shaped clamp 1, thereby further increasing the clamping force of the arc-shaped clamp 1 on the shock-absorbing cylinder; during this process, the angles between the docking component and the internally threaded slider 4 and between the limiting component and the internally threaded slider 4 are constantly changing.

[0040] Since the position of the internally threaded slider 4 will be locked after the lead screw column 3 stops rotating, the stability of the adjusting mechanism is ensured, and the risk of the shock-absorbing cylinder disengaging from the arc-shaped clamp 1 is reduced.

[0041] Through the mutual cooperation of the adjusting structure, the docking component and the limiting component, the applicable range of the arc-shaped clamp 1 can be increased, and the arc-shaped clamp 1 can stably provide a clamping force for the shock-absorbing cylinder to prevent the shock-absorbing cylinder from being misaligned.

[0042] As a further solution of the present utility model, the docking component includes a hinge platform 6 rotatably installed on one of the internally threaded sliders 4, a connecting column 601 is rotatably installed on the hinge platform 6, a shrinkage joint 602 is provided on the connecting column 601, and an arc-shaped boss 603 is installed at one end of the connecting column 601 away from the hinge platform 6.

[0043] As a further solution of the present utility model, the limiting component includes a connecting sleeve 5 rotatably installed on the other internally threaded slider 4, and a clamping groove 501 is provided on the connecting sleeve 5.

[0044] In this embodiment, the docking component and the limiting component cooperate with each other. Insert the connecting column 601 into the connecting sleeve 5. Since the distance between the outermost ends of the two arc-shaped bosses 603 is greater than the inner diameter of the connecting sleeve 5, during the insertion process, the two arc-shaped bosses 603 will approach each other, so that the distance of the shrinkage joint 602 becomes smaller, so that the connecting column 601 can be smoothly inserted into the connecting sleeve 5.

[0045] After the connecting column 601 enters the clamping groove 501, since the diameter of the clamping groove 501 is greater than the inner diameter of the connecting sleeve 5, the inner wall of the connecting sleeve 5 will no longer press the connecting column 601, so that the two arc-shaped bosses 603 move away from each other, and the distance of the shrinkage joint 602 will become larger.

[0046] After the connecting column 601 enters the engaging groove 501, the engaging groove 501 restricts the connecting column 601, preventing it from separating from the connecting sleeve 5.

[0047] Through the mutual cooperation of the adjusting structure with the docking component and the limiting component, the applicable range of the arc-shaped hoop 1 can be increased, and the arc-shaped hoop 1 can stably provide a clamping force for the shock-absorbing cylinder to prevent the shock-absorbing cylinder from being misaligned.

[0048] As a further solution of the present invention, the surface of the arc-shaped boss 603 close to the hinge platform 6 is set as an inclined surface that contracts away from the hinge platform 6; the surface of the engaging groove 501 away from the internal thread slider 4 is set as a slope extending towards the internal thread slider 4, and the inclined surface and the slope can be mutually engaged.

[0049] In this embodiment, after the arc-shaped boss 603 enters the engaging groove 501, the inclined surface can be engaged with the slope, thereby increasing the limiting effect of the engaging groove 501 on the arc-shaped boss 603, making it more difficult for the connecting column 601 to disengage from the connecting sleeve 5, and thus improving the stability of the arc-shaped hoop 1 in fixing the shock-absorbing cylinder.

[0050] As a further solution of the present invention, an internal thread groove 502 is formed on the connecting sleeve 5, an external thread block 7 is threadedly connected in the internal thread groove 502, and a protruding plate 701 is installed on the external thread block 7.

[0051] In this embodiment, since the width of the engaging groove 501 is greater than the width of the arc-shaped boss 603 (which is beneficial for the inclined surface of the arc-shaped boss 603 to be engaged with the slope of the engaging groove 501), the arc-shaped boss 603 can freely slide in the engaging groove 501; this makes the clamping force of the arc-shaped hoop 1 on the shock-absorbing cylinder unstable.

[0052] After the arc-shaped boss 603 enters the engaging groove 501, the protruding plate 701 will enter the shrinkage seam 602. At this time, the connecting column 601 is rotated, and the protruding plate 701 is driven by the connecting column 601 to rotate synchronously, causing the external thread block 7 to be threadedly engaged with the internal thread groove 502, so that the external thread block 7 gradually pushes the connecting column 601 towards the hinge platform 6 until the inclined surface and the slope are completely engaged, thereby enabling the arc-shaped hoop 1 to stably provide a clamping force for the shock-absorbing cylinder to prevent the shock-absorbing cylinder from being misaligned.

[0053] As a further solution of the present invention, a hexagonal boss 301 is installed at one end of the screw rod column 3 away from the connecting block 2.

[0054] In this embodiment, the hexagonal boss 301 can reduce the difficulty of rotating the screw rod column 3, thereby reducing the difficulty of installing the arc-shaped hoop 1.

[0055] The above embodiments are illustrative rather than restrictive, so without departing from the spirit or basic characteristics of the present invention, all technical solutions that can implement the present invention in other specific forms are included within the present invention.
