Description

Technical Field

[0001] This utility model relates to the field of vehicle frame technology, and in particular to a shock-absorbing vehicle frame. Background Technology

[0002] In the manufacturing of bicycles and similar vehicles, the design of suspension frames has always been key to improving the riding experience. However, existing suspension frame designs face a series of challenges in balancing performance optimization and cost-effectiveness, as well as structural simplification and durability.

[0003] On the one hand, some suspension frame designs adopt a simpler structure in order to reduce costs and improve maintenance convenience. For example, some designs simplify the structure by reducing the number of components in the suspension system. However, such designs often result in unsatisfactory shock absorption. Specifically, these simplified suspension frames may lack sufficient shock travel or adjustment range, and cannot effectively cope with vibrations under different road conditions, thus affecting the rider's comfort and handling stability.

[0004] On the other hand, some suspension frame designs are overly complex, pursuing ultimate shock absorption performance. These designs typically include multiple precision components and complex connection mechanisms. While they improve shock absorption to some extent, they also bring high manufacturing costs and greater maintenance difficulty. In addition, complex suspension systems often require a high level of user skill, making it difficult for ordinary users to quickly get started and use them daily. Specifically, some complex suspension frames may include multiple layers of shock springs, multiple shock absorbers, and complex hydraulic systems. While these designs can provide excellent shock absorption performance, the coordination and adjustment between components require a high degree of precision. Once a malfunction occurs or maintenance is needed, it often requires professional technicians to handle it. This not only increases the user's maintenance costs but may also affect the long-term performance of the frame.

[0005] Therefore, the industry urgently needs a shock-absorbing frame design that can maintain high-efficiency shock absorption performance, and is simple in structure, easy to maintain, and cost-effective. Based on this, the applicant has proposed a shock-absorbing frame to solve the above technical problems. Utility Model Content

[0006] This utility model addresses the shortcomings of existing technologies by providing a shock-absorbing vehicle frame to solve the aforementioned technical problems.

[0007] This utility model is solved by the following technical solution:

[0033] The technical solutions of various embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1:

[0034] like Figures 1 to 9 As shown, a shock-absorbing bicycle frame of this utility model includes a connecting seat 2 fixedly mounted on a bracket 1. A rocker arm 5 is rotatably connected to the connecting seat 2. A shock absorber 6 is also rotatably mounted on the bracket 1. The upper end of the shock absorber 6 is rotatably mounted on one end of the rocker arm 5. An upper fork joint 3 is rotatably mounted on the other end of the rocker arm 5 for fixing the upper fork. A lower fork joint 4 is also rotatably mounted on the bracket 1 for fixing the lower fork. The end of the upper fork away from the upper fork joint 3 is connected and fixed to the end of the lower fork away from the lower fork joint 4.

[0035] When encountering bumpy roads during riding, the lower fork causes the lower fork joint 4 to rotate, which in turn causes the upper fork and upper fork joint 3 to rotate together. The rotation of the upper fork joint 3 causes the rocker arm 5 to rotate, which in turn causes the shock absorber 6 to work. The shock absorber 6 absorbs the vibration, thereby achieving the purpose of shock reduction.

[0036] This device, through its reasonable component layout and connection method, enables the shock absorber to more effectively absorb and disperse vibrations generated during riding. This not only improves the rider's comfort but also enhances the frame's handling stability, allowing the rider to cope more easily with complex road conditions.

[0037] The rocker arm 5 has a connecting hole E53 in the middle, and the connecting seat 2 has a connecting ear. The connecting hole E53 is connected to the connecting ear. One end of the rocker arm 5 has a connecting hole D52. The upper end of the shock absorber 6 is connected to the connecting hole D52 by bolts. The other end of the rocker arm 5 has a connecting hole C51. The upper fork joint 3 has a connecting hole A31. The connecting hole C51 and the connecting hole A31 are coaxially rotatably connected. The rocker arm 5 also has a material-reducing groove 54, which reduces the weight of the whole vehicle while ensuring the strength of the frame, and improves the rider's handling experience and speed performance.

[0038] The upper fork connector 3 is symmetrically provided with upper fork connecting parts 32, which are fixedly connected to the upper fork by welding. The lower fork connector 4 includes connector assemblies 41 symmetrically arranged at both ends of the connecting rod 44. One end of the connector assembly 41 is provided with a lower fork connecting part 42, which is fixedly connected to the lower fork by welding. The other end of the connector assembly 41 is provided with a connecting hole B43. A fixing seat 7 is fixedly provided on the bracket 1, and the connecting hole B43 is connected to the fixing seat 7.

[0039] A bearing seat 8 is also fixedly installed on the bracket 1, and the lower end of the shock absorber 6 is rotatably connected to the bearing seat 8.

[0040] All of the above-mentioned rotating parts can be connected by bolts. To ensure smooth rotation, bearings can be installed between the two parts.

[0041] The aforementioned connecting seat 2, fixing seat 7, and shaft seat 8 are all fixedly mounted on the bracket 1 by welding. In other examples, this fixing method can also be replaced by a detachable fixing connection method, such as a bolted connection.

[0042] By reducing unnecessary parts and complex connection mechanisms, this device lowers the manufacturing cost of the suspension frame. At the same time, the simplified structure reduces friction and wear between parts, extends the frame's service life, and lowers maintenance costs. The simplified structure and innovative connection method make the suspension frame of this device easier to maintain and operate. Users do not need professional skills or tools to easily perform daily inspections and maintenance, lowering the barrier to entry.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and not restrictive in all respects. The scope of this invention is defined by the appended claims, not by the foregoing description, and is therefore intended to encompass all variations falling within the meaning and scope of equivalents of the claims. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
