Technical Field
[0001] This utility model belongs to the field of bicycle technology, and in particular relates to a shock-absorbing bicycle. Background Technology
[0002] A bicycle is a human-powered mode of transportation, typically composed of a frame, wheels, handlebars, seat, and drivetrain. Cycling is not only an environmentally friendly mode of transportation but also a popular sport and recreational activity. The shock absorption performance and frame strength of a bicycle are key factors, directly affecting riding comfort and safety. Shock absorption is primarily achieved through the front fork and rear suspension system, effectively absorbing vibrations from uneven road surfaces and improving ride smoothness and comfort. Frame strength determines the bicycle's durability and load-bearing capacity; a high-strength frame can withstand greater impact forces and ensure stability and safety during high-intensity riding or on complex terrain. Therefore, good shock absorption and a high-strength frame are essential characteristics of a high-quality bicycle, significantly enhancing the riding experience and ensuring rider safety.
[0003] Currently, existing bicycle suspension designs often inevitably sacrifice the overall strength and stability of the frame. Firstly, while the addition of suspension systems, such as the front fork and rear shock absorber, improves riding comfort, it weakens the overall structural rigidity, often leading to stress concentration and uneven load distribution. As a result, the frame is prone to deformation and even breakage during use, especially during high-intensity riding or on complex terrain.
[0004] Secondly, the weight and structure of the shock absorption system itself place an additional burden on the frame. The shock absorber connection struggles to balance shock absorption effectiveness with frame strength, resulting in a weakening of the frame's overall strength and durability while bearing the weight of the shock absorption system. For example, the shock absorber connecting rod not only has to withstand vibrations, but the shock absorber pin also bears lateral torque. This weakening not only affects the bicycle's lifespan but also reduces riding safety to some extent.
[0005] Furthermore, existing shock absorber designs often fail to adequately consider the dynamic performance of the frame. When operating, shock absorbers exert forces on the frame in different directions. Repeated application of these forces can lead to fatigue damage to the frame. Prolonged stress accumulation gradually weakens the frame's stability, causing it to exhibit insufficient strength at critical moments.
[0006] Therefore, existing bicycle shock absorption designs have obvious shortcomings while achieving shock absorption effects, and improvements need to be made in the design process. Utility Model Content

[0012] The advantages and effects of this utility model are:
[0013] The shock-absorbing bicycle proposed in this invention has many advantages and significant effects. First, the frame adopts a multi-link frame structure. This design not only effectively improves shock absorption performance but also evenly distributes stress, reducing the stress on any single part and ensuring the overall strength and durability of the frame. Second, through the design of multi-hinged stabilizing links, the link frame is tightly integrated with the original bicycle frame, providing shock absorption while further enhancing the stability of the frame and preventing deformation or damage under high-intensity use.
[0014] Furthermore, this design significantly reduces stress in other directions on the pin, lowering the likelihood of wear and extending the lifespan of the pin and related components. Because stress is distributed more evenly, riders experience a smoother and more comfortable ride across various road conditions. This not only improves riding comfort but also enhances safety, especially on challenging terrain or long-distance riding.
[0015] In summary, this invention's shock-absorbing bicycle maintains excellent shock absorption while achieving a dual improvement in overall frame strength and stability through a multi-link frame and multi-hinged shaft stabilizing link design. It also effectively reduces wear on key components, significantly improving the bicycle's durability and safety. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.
[0018] To address the issue that existing bicycle shock absorption designs, while improving riding comfort, compromise the overall strength and stability of the frame, this invention provides a shock-absorbing bicycle. This shock-absorbing bicycle, through a multi-link and multi-hinge design, achieves superior shock absorption, overall frame strength and stability, and reduces wear on key components. To further illustrate the structure of this invention, a detailed description is provided below in conjunction with the accompanying drawings:
[0019] Please see Figure 1 A shock-absorbing bicycle includes a front frame 1, a front fork 2, a rear fork 3, a rear support 4, a connecting rod 5, a rear shock absorber 6, a front support rod 7, a front shock absorber 8, and a front support 9.
[0020] The front frame is the central main frame of a bicycle. The front fork is used to mount the handlebars and front wheel, while the rear fork is used to mount the rear wheel. The front frame, front fork, and rear fork form the basic structure of a modern bicycle.
[0021] In this embodiment, the front frame includes an upper cross tube 1-1, a lower slant tube 1-2, and a saddle seat upright tube 1-3. The upper cross tube, lower slant tube, and saddle seat upright tube are welded to form a triangular frame structure. The front ends of the upper cross tube and lower slant tube are welded with fork upright tubes for mounting the front fork frame, while the saddle seat upright tube is used to mount the saddle. The lower ends of the lower slant tube and the saddle seat upright tube form a five-way hole, and the rear part of this five-way hole is connected to the rear fork frame.
[0022] The front fork is mounted at the front of the front frame, and the rear fork is mounted at the rear of the front frame via a first pin 10. The axis of the first pin is parallel to the axis of the bicycle's bottom bracket, and the rear fork forms a structure in which the tail swings around the first pin.
[0023] The rear end of the rear support is connected to the rear fork via a second pin 11, and the front end of the rear support is hinged to one end of the linkage via a third pin 12. The other end of the linkage is hinged to the front frame via a fourth pin 13. In this embodiment, two rear supports are symmetrically arranged on both sides of the saddle seat riser, and the front ends of the two rear supports are hinged to the lower end of the linkage via a third pin. One end of the rear shock absorber is connected to the rear support and the linkage via a third pin, and the other end of the rear shock absorber is hinged to the front frame via a fifth pin 14. Specifically, the upper end of the linkage is hinged to the upper cross tube via a fourth pin, and the front end of the rear shock absorber is hinged to the lower slant tube via a fifth pin. The linkage and the rear shock absorber are located inside the triangular frame structure. The rear shock absorber uses a damping spring, and a seat frame is welded onto the slant tube. The front end of the rear shock absorber is hinged to this seat frame via a fifth pin.
[0024] The lower end of the fork is hinged to one end of the front support via a sixth pin 15, and the other end of the front support is used to mount the front wheel. The fork forms fork arms located on both sides of the front wheel, while the front support is a support symmetrically arranged on both sides of the front wheel, forming a support arm extending forward from the lower end of the fork. The front end of the front support has an axle hole for mounting the front wheel.
[0025] The front strut is a symmetrical strut located on both sides of the front wheel. The lower end of the front strut is hinged to the middle of the front support via the seventh pin 16. This middle part does not define the geometric center of the front support, but rather refers to the area between the front and rear hinge points of the front support. The upper end of the front support connects to one end of the front shock absorber, and the other end of the front shock absorber connects to the front frame. In this embodiment, specifically, a shock absorber bracket is installed on the upper part of the front frame.
