Description

Technical Field

[0001] This utility model relates to the field of shock-absorbing vehicle frames, specifically a double-limiting linkage rocker arm type shock-absorbing vehicle frame. Background Technology

[0002] The dual-limit linkage swingarm suspension frame of a bicycle is a meticulously designed structure aimed at significantly improving shock absorption and stability during riding. The frame primarily consists of a front triangle and a rear triangle, with the rear triangle further divided into upper and lower forks. These components are precisely connected to key parts of the front triangle, such as the center tube and downtube. To effectively control the frame's movement during shock absorption, upper and lower limit linkages are cleverly incorporated within the frame. These linkages are flexibly connected to different positions on the frame. The shock absorber is then tightly connected to these limit linkages via the swingarm, forming a highly efficient linkage mechanism. When the wheel encounters an impact, the shock absorber responds quickly, utilizing the synergistic effect of the dual swingarms to compress and rebound, thereby ensuring the frame achieves ideal balance during dynamic riding and providing the rider with a smoother and more comfortable riding experience.

[0003] During long-term use, the sealing rings of shock absorbers in limit linkage rocker arm type suspension frames are constantly exposed to rain and other factors. If further exposed to harsh environments such as wind and rain, rainwater, dust, and other debris can easily enter the shock absorber through the continuous movement of the shock absorber's moving rod. These intruders will accelerate the wear inside the shock absorber, affect its lubrication, and may even lead to oil leakage or damage to internal parts, ultimately causing a decline in shock absorber performance or even complete failure. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a double-limiting linkage rocker arm type shock absorber frame to solve the technical problem that rainwater, dust and other debris can enter the shock absorber due to the wear of the sealing ring in the limiting linkage rocker arm type shock absorber frame, thereby aggravating the internal wear of the shock absorber, affecting the lubrication effect, and potentially causing oil leakage or damage to internal parts, ultimately leading to a decline in the performance of the shock absorber or even complete failure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-limiting linkage rocker arm type shock absorber frame, including a frame, the frame including a main frame, a handlebar frame, and a front wheel frame, two second shock absorbers are provided below the front wheel frame, and a sliding rod is provided on the top of the two second shock absorbers, and the sliding rod is detachably connected to the front wheel frame through a fixing head;

A first sealing mechanism is installed inside the first mounting screw groove. The first sealing mechanism includes a first folding cover. The top and bottom of the first folding cover are provided with first threaded rings. The first threaded rings are screwed into the first mounting screw groove.

[0007] The second shock absorber has a first mounting ring slidably connected to its outer side. The first mounting ring is screwed to another first threaded ring. A limit ring is provided above the outer side of the second shock absorber, and the limit ring is used to restrict the first mounting ring.

[0008] By adopting the above technical solution, and by installing two second shock absorbers under the front wheel frame, and equipping them with slide bars and fixing heads to achieve detachable connection, the shock absorption performance of the frame is enhanced.

[0009] Furthermore, a rear wheel frame is rotatably connected to the back of the main frame, and a first shock absorber is detachably connected between the main frame and the rear wheel frame via a connector.

[0010] By adopting the above technical solution, the first shock absorber is detached and connected between the main frame and the rear wheel frame through a connector, thus achieving flexibility and maintainability of the rear shock absorber of the vehicle frame.

[0011] Furthermore, a second sealing mechanism is provided on the outer side of the first shock absorber. The second sealing mechanism includes a second mounting ring, which is slidably connected to the first shock absorber.

[0012] By adopting the above technical solution, a second sealing mechanism is set on the outside of the first shock absorber, which further enhances the sealing performance of the shock absorber.

[0013] Furthermore, the sliding rod end of the first shock absorber is provided with a fixing plate, and the fixing plate is provided with a second mounting screw groove.

[0014] By adopting the above technical solution, a fixing plate is set at the end of the slide bar of the first shock absorber, and a second mounting screw groove is opened, which facilitates the installation of the second sealing mechanism.

[0017] Furthermore, the second folding cover has two second threaded rings at both ends, and the two second threaded rings are respectively screwed into the second mounting ring and the second mounting screw groove.

[0018] By adopting the above technical solution, the two ends of the second folding cover are provided with second threaded rings, which are respectively screwed to the second mounting ring and the second mounting screw groove, thereby enhancing the stability and sealing performance of the sealing mechanism.

[0019] Furthermore, a handlebar frame is rotatably connected to the front end of the main frame, and a front wheel frame is detachably connected to the bottom of the handlebar frame.

[0020] By adopting the above technical solution, the front end of the main frame is rotatably connected to the handlebar frame, and the bottom of the handlebar frame is detachably connected to the front wheel frame. This design makes the frame more flexible in handling.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. This utility model solves this problem by setting a second sealing mechanism, while the double-limiting linkage rocker arm type shock absorber frame effectively solves this problem by introducing a first sealing mechanism, especially the first folding cover and the first threaded ring that cooperates with it. The first folding cover can flexibly fold or unfold with the extension and retraction of the shock absorber, always maintaining a tight cover over the shock absorber, thereby effectively blocking the intrusion of rainwater, dust and other debris. At the same time, the first threaded ring is screwed into the first mounting screw groove on the frame, ensuring the stable installation of the sealing mechanism and easy disassembly and maintenance. This design not only improves the sealing performance of the shock absorber and extends its service life, but also significantly improves the durability and stability of the entire frame. For riders, this means a safer and more comfortable riding experience, as well as lower maintenance costs and usage risks.

[0023] 2. This utility model, by setting a second sealing mechanism, which consists of a second mounting ring, a second folding cover, and a second threaded ring, constructs a solid additional sealing barrier for the first shock absorber. This multi-layer sealing design not only effectively isolates external debris and moisture from intrusion, thereby ensuring that the key components inside the shock absorber are not damaged, but also greatly improves the durability of the shock absorber. Due to this additional protection, the lubricating grease and other core components inside the shock absorber can be kept clean, thereby reducing the risk of wear and corrosion caused by external pollution and significantly extending the service life of the shock absorber.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as limiting the present utility model.

[0030] Example 1:

[0031] A type of double-limiting linkage rocker arm suspension frame, such as Figures 1-4 As shown, the vehicle includes a frame, which comprises a main frame, a handlebar frame, and a front wheel frame. Two second shock absorbers are mounted below the front wheel frame. Each second shock absorber has a sliding rod at its top, and the sliding rod is detachably connected to the front wheel frame via a fixing head. A first mounting screw groove is formed on the bottom of the front wheel frame near the outer side of the sliding rod. A first sealing mechanism is installed inside the first mounting screw groove. The first sealing mechanism includes a first folding cover, and first threaded rings are provided at the top and bottom of the first folding cover. The first threaded rings are screwed into the first mounting screw groove. The outer side of the second shock absorber slides... The moving connection has a first mounting ring, which is screwed to another first threaded ring. A limit ring is provided on the upper outer side of the second shock absorber, and the limit ring is used to restrict the first mounting ring. By setting two second shock absorbers under the front wheel frame and equipping them with slide rods and fixing heads to achieve disassembly and connection, this design not only enhances the shock absorption effect of the frame, but also improves the convenience of maintenance. At the same time, the introduction of the first sealing mechanism, especially the screw connection design of the first folding cover and the first threaded ring with the first mounting screw groove, effectively prevents external impurities from entering the shock absorber and extends the service life of the shock absorber.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4The rear wheel frame is rotatably connected to the back of the main frame. A first shock absorber is detachably connected between the main frame and the rear wheel frame via a connector. This design makes the rotation of the rear wheel frame more flexible and facilitates the replacement or repair of the first shock absorber, reducing maintenance costs and improving the overall stability and driving safety of the frame.

[0033] Example 2:

[0034] See Figure 1 , Figure 4 The first shock absorber is provided with a second sealing mechanism on its outer side. The second sealing mechanism includes a second mounting ring, which is slidably connected to the first shock absorber. The second sealing mechanism provided on the outer side of the first shock absorber, especially the sliding connection between the second mounting ring and the shock absorber, provides additional sealing protection for the shock absorber. This design effectively prevents external factors such as dust and moisture from entering the shock absorber, reduces wear and malfunctions, and improves the performance and durability of the shock absorber.

[0035] See Figure 2 , Figure 3 The first shock absorber has a fixing plate at the end of its slide rod, and the fixing plate has a second mounting screw groove. The fixing plate at the end of the slide rod of the first shock absorber and the second mounting screw groove provide a stable support for the installation of the second sealing mechanism. This design enhances the connection strength between the sealing mechanism and the shock absorber, prevents the sealing mechanism from falling off or being damaged during driving, and ensures the durability of the sealing effect.

[0036] See Figure 3 , Figure 4 A second folding cover is provided between the second mounting screw groove and the second mounting ring. The second folding cover between the second mounting screw groove and the second mounting ring realizes dynamic sealing of the shock absorber slide rod. When the slide rod extends or retracts, the second folding cover can fold and unfold flexibly, always maintaining a tight seal, effectively preventing external impurities and moisture from entering the shock absorber and protecting the core components of the shock absorber.

[0037] See Figure 1 , Figure 2 The second folding cover has two second threaded rings at both ends. The two second threaded rings are screwed into the second mounting ring and the second mounting screw groove respectively. The second threaded rings at both ends of the second folding cover are screwed into the second mounting ring and the second mounting screw groove respectively. This design not only enhances the stability of the sealing mechanism, but also makes the sealing mechanism easier to install and disassemble. At the same time, the screw connection method also improves the durability and reliability of the sealing mechanism, ensuring a long-term sealing effect.

[0038] See Figure 1 , Figure 4 The front end of the main frame is rotatably connected to a handlebar frame, and the bottom of the handlebar frame is detachably connected to a front wheel frame. This design, with the handlebar frame rotatably connected to the front end of the main frame and the front wheel frame detachably connected to the bottom of the handlebar frame, makes the frame more flexible and convenient to handle. At the same time, the detachable connection method facilitates quick replacement or repair of the front wheel frame, improving the maintainability and practicality of the frame. In addition, this structure also helps to optimize the weight distribution of the frame, improving the vehicle's driving stability and handling performance.

[0039] The implementation principle of this utility model is as follows: First, the main frame is used as the core component to ensure that its main structure is stable. Then, the handlebar frame is installed to the front end of the main frame by a rotating connection to facilitate the driver's control of the vehicle. Then, the front wheel frame is installed to the bottom of the handlebar frame by a detachable connection to ensure that the front wheel can be stably supported and steered.

[0040] Two second shock absorbers are installed below the front wheel frame. They are detached and connected to the front wheel frame via a sliding rod and a fixing head, which facilitates subsequent maintenance and replacement. On the outside of the second shock absorber, a first mounting ring is slidably connected, and a first sealing mechanism is installed by screwing a first threaded ring into a first mounting screw groove to ensure the sealing of the shock absorber. At the same time, a limiting ring is used to restrict the position of the first mounting ring to prevent it from sliding excessively.

[0041] The rear wheel bracket is mounted to the back of the main frame via a rotating connection to ensure stable support of the rear wheels for the vehicle. A first shock absorber is detached and connected between the main frame and the rear wheel bracket via a connector to improve the vehicle's shock absorption performance. Meanwhile, a second mounting ring is slidably connected to the outside of the first shock absorber as part of the second sealing mechanism. A fixing plate is installed at the end of the slide bar of the first shock absorber, and a second mounting screw groove is formed. A second folding cover is installed between the second mounting screw groove and the second mounting ring, and is screwed to the second mounting ring and the second mounting screw groove via a second threaded ring to ensure a tight seal.
