Description

Technical Field

[0001] This utility model relates to a field, specifically a vibration damping device for bicycle rear suspension. Background Technology

[0002] Bicycles, as an environmentally friendly and healthy mode of transportation, are widely used in daily life and leisure activities. However, during riding, especially on rough roads, bicycles are subjected to impacts and vibrations from the road surface, which not only affects riding comfort but may also damage the bicycle's structure and components.

[0003] Existing bicycle rear suspension systems can mitigate road impacts to some extent, but their vibration damping effect is limited. Traditional rear suspension systems typically use elastic elements such as springs or rubber to absorb impact energy, but these elements are not ideal in damping vibrations. When a bicycle encounters a large impact, the rear suspension system may generate excessive vibration, leading to riding instability and even affecting the rider's safety. Utility Model Content

[0004] The purpose of this invention is to provide a vibration damping device for a bicycle rear suspension to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vibration damping device for a bicycle rear suspension includes a frame assembly, which further includes a lower frame and an upper frame. A fixing post is fixedly connected to the bottom of the upper frame, a support post is fixedly connected to the top of the fixing post, a welding rod is fixedly connected to the bottom of the fixing post, and a cavity is fixedly connected to the bottom of the welding rod. The bottom of the lower frame is fixedly connected to the outer wall of the cavity, and a hinge is provided at the lower part of the outer wall of the lower frame.

[0007] As a further embodiment of this utility model: a damping spring is installed in the slot of the second hinge, and the top of the damping spring is hinged to the slot of the second hinge, and the first hinge is installed thereon.

[0008] As a further embodiment of this utility model: a rear axle is fixedly connected to the outer wall of the pivot of the first hinge member, and a rear wheel rod is hinged to the end of the rear axle away from the first hinge member.

[0009] As a further embodiment of this utility model: a connecting rod is installed on the lower inner part of the rear wheel rod one and the rear wheel rod two, and a rear wheel rod three and a rear wheel rod four are respectively installed on the left and right sides of the connecting rod.

[0010] As a further embodiment of this utility model: the rear wheel rod three and the rear wheel rod four are welded to the front axle at the ends away from the connecting rod, the front end of the front axle is equipped with a hinge member two, the front end of the hinge member two is provided with a damping spring, and the damping spring is hinged to the front axle.

[0011] As a further improvement of this utility model, the lower part of the outer wall of the welding rod is open.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, when the bicycle is subjected to external force, rear wheel levers two and one are pressed down, which in turn pushes rear wheel levers three and four down. The front axle connected to the front ends of rear wheel levers three and four will push the damping spring hinged by hinge two to contract, thus achieving a shock absorption effect. The damping spring is located in the slot of hinge two, and hinge one, which is hinged to the upper part of the slot of hinge two, is used to connect with rear wheel levers one and two. When rear wheel levers one and two are subjected to force, they will also push the rear axle, causing the damping spring hinged by hinge one to swing. This will not cause damage to the pressure after the damping spring has extended or contracted. Its structure is more optimized and its design is more reasonable. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3In this embodiment of the utility model, a bicycle rear suspension vibration damping device includes a frame assembly 1, which further includes a lower frame 2 and an upper frame 3. The bottom of the upper frame 3 is fixedly connected to a fixing post 5, the top of the fixing post 5 is fixedly connected to a support post 4, the bottom of the fixing post 5 is fixedly connected to a welding rod 12, the bottom of the welding rod 12 is fixedly connected to a cavity 11, the bottom of the lower frame 2 is fixedly connected to the outer wall of the cavity 11, and a hinge 17 is provided on the lower part of the outer wall of the lower frame 2.

[0020] A damping spring 14 is installed in the slot of hinge 2 17, and hinge 15 is hinged to the top of the damping spring 14 and the slot of hinge 2 17.
