Description

Technical Field

[0001] This invention belongs to the field of tricycles, specifically relating to a wear-resistant brake lever assembly suitable for recreational tricycles and a frame equipped with the assembly. Background Technology

[0002] Currently, recreational tricycles are widely used for children's entertainment and leisure transportation. To ensure riding safety, recreational tricycles are usually equipped with a foot brake system, allowing riders to decelerate and brake the vehicle by operating their feet. However, existing recreational tricycle foot brake lever assemblies generally have the following defects and shortcomings:

[0003] Easy to wear and affect service life: The shaft and bracket in the existing foot brake lever assembly are mostly made of metal parts directly connected. After long-term use, the friction between the metals causes severe wear on the mating surfaces, which in turn leads to loosening and affects braking sensitivity and safety.

[0004] Loud brake noise affects the riding experience: Due to the lack of effective cushioning and lubrication structures, friction between metal rotating parts produces abnormal noise, which is especially noticeable when riding outdoors.

[0005] Poor corrosion resistance and easy to rust: In humid or rainy environments, metal parts are prone to rust, leading to problems such as structural jamming and brake failure.

[0006] Frequent maintenance and inconvenient use: Because the existing structural design does not take into account bushings or wear-resistant parts, users need to frequently maintain lubrication and fasteners, increasing the cost of use and operational complexity.

[0007] Therefore, there is an urgent need for a wear-resistant brake lever assembly for recreational tricycles that is simple in structure, has good wear resistance, low noise, long service life, and is easy to maintain, in order to solve the problems existing in the prior art. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wear-resistant brake lever assembly suitable for recreational tricycles, which can solve the problems of easy wear, poor corrosion resistance, and high braking noise in the braking system, as well as a frame equipped with the assembly.

[0009] To solve the above-mentioned technical problems, the technical method adopted by the present invention is as follows: The present invention discloses a wear-resistant brake lever assembly suitable for recreational tricycles, including a foot brake lever assembly and a rear brake linkage assembly, characterized in that: the foot brake lever assembly includes a foot brake lever bracket and a foot brake lever shaft, and the foot brake lever shaft is provided with an annular foot brake wear-resistant bushing that matches the side of the foot brake lever bracket;

[0010] The foot brake lever pivot is mounted on the foot brake lever bracket via the annular foot brake wear-resistant bushing, and can swing relative to the foot brake lever pivot.

[0011] Furthermore, the annular foot brake wear-resistant bushing is made of a polymer material with self-lubricating and wear-resistant properties to reduce direct contact between the foot brake lever shaft and the foot brake lever bracket, reduce braking noise, and prevent corrosion.

[0012] Furthermore, the polymer material is a reinforced nylon material, preferably a PA material reinforced with glass fibers, and its surface is provided with a lubricating coating.

[0013] Furthermore, the inner surface of the foot brake lever shaft is provided with an anti-slip texture or an anti-corrosion coating to enhance its stability during rotation and improve its corrosion resistance.

[0014] Furthermore, the annular brake wear-resistant bushing is provided with sealing flanges on both sides that wrap around the tube walls on both sides of the foot brake lever shaft.

[0015] Furthermore, the rear brake linkage assembly includes a brake linkage shaft and a brake lever fixing plate. The brake lever fixing plate has an annular brake wear-resistant bushing that fits against the inner wall of the brake lever fixing plate. The annular brake wear-resistant bushing covers the side of the brake linkage shaft, and the brake linkage shaft can rotate relative to the annular brake wear-resistant bushing.

[0016] Furthermore, the outer surface of the annular brake wear-resistant bushing is provided with an anti-rotation protrusion structure, which is inserted into the limiting groove provided in the brake rod fixing plate to prevent the wear-resistant bushing from rotating together with the brake linkage shaft during use.

[0017] Furthermore, limit structures are provided at both ends of the brake linkage shaft, and the limit structures include elastic retaining rings or bolt assemblies.

[0018] The present invention also discloses a frame based on any of the above-mentioned wear-resistant brake lever assemblies suitable for recreational tricycles. The tricycle includes a front wheel steering system, a frame, any of the above-mentioned foot brake lever assemblies and a rear brake linkage assembly. The foot brake lever assembly and the rear brake linkage assembly are connected by a brake linkage system to achieve synchronous braking.

[0019] Furthermore, one end of the foot brake lever bracket is fixed to the vehicle frame, and the other end is provided with a locking bolt. Beneficial effects

[0020] 1. This utility model significantly improves the wear resistance and corrosion resistance of the components by introducing high-performance wear-resistant bushings into the foot brake lever assembly and the rear brake linkage assembly, and by applying an anti-corrosion coating and an anti-slip structure to the surface of the brake lever shaft. The above structure effectively reduces the wear rate and corrosion risk of the components during long-term use, extends the overall service life, and improves the durability and safety of the tricycle.

[0021] 2. This utility model adds a limiting protrusion and a self-lubricating wear-resistant bushing to the brake system structure design, and prevents dust and impurities from entering the rotating mating area through a sealed flange structure, thereby achieving improved sensitivity and stability of brake operation and significantly reducing noise during braking. This technology optimizes and ensures a quiet and smooth riding experience, improving user comfort and riding safety.

[0022] 3. The recreational tricycle provided by this utility model has a compact overall structure. Combined with the aforementioned high-performance, wear-resistant brake lever assembly, it forms a highly efficient and interconnected braking control system. Through reasonable structural design and material selection, the braking system and overall vehicle performance are synergistically optimized, significantly improving the braking safety and stability of the vehicle, and possessing excellent market application prospects.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] Example 1: A wear-resistant brake lever assembly suitable for recreational tricycles

[0030] like Figures 1 to 4 As shown, the wear-resistant brake lever assembly includes a foot brake lever assembly 1 and a rear brake linkage assembly 2.

[0031] The foot brake lever assembly 1 includes a foot brake lever bracket 11, a foot brake lever shaft 12, and an annular foot brake wear-resistant bushing 31 installed on the outer periphery of the shaft 12;

[0032] The rear brake linkage assembly 2 includes a brake linkage shaft 21, a brake lever fixing plate 22, and an annular brake wear-resistant bushing 32.

[0033] The foot brake lever bracket 11 is fixed to the side of the frame 6 by bolts. The foot brake lever pivot 12 is equipped with a brake cable pull plate 13 and a foot brake pedal tube 14. The brake cable pull plate 13 provides a connection and installation point for the brake cable; the foot brake pedal tube 14 transmits the braking action to the brake cable when the foot brake is used.

[0034] The foot brake lever shaft 12 is mounted on the foot brake lever bracket 11 via a wear-resistant bushing 31. Preferably, the outer surface of the foot brake lever shaft 12 is provided with anti-slip texture and anti-corrosion coating to ensure stable rotation.

[0035] Preferably, the wear-resistant bushing 31 is made of reinforced PA66+PTFE material, with a lubricating coating on the surface, which has self-lubricating and wear-resistant properties, and is provided with sealing flanges 310 on both sides to effectively prevent impurities from entering.

[0036] The rear brake linkage assembly 2 has a similar structure to the foot brake lever assembly 1, with the brake linkage shaft 21 mounted inside the brake lever fixing plate 22 via a wear-resistant bushing 32. Preferably, the annular brake wear-resistant bushing 32 has an anti-rotation protrusion to prevent the bushing from rotating with the shaft.

[0037] The brake linkage shaft 21 is equipped with a rear brake lever brake cable rocker arm 5, which provides a connection and installation point for the brake cable. After the brake cable is installed, the internal back-and-forth movement of the cable core is switched to circular movement.

[0038] A brake lever rocker arm limiting piece 51 is fixed on the brake linkage shaft 21, which can work in conjunction with the rear brake lever brake cable rocker arm 5 to switch the internal back-and-forth movement of the cable core to circular motion.

[0039] Preferably, a support piece 23 for supporting the brake linkage shaft 21 is also provided on one side of the brake linkage shaft 21.

[0040] Example 2: A frame suitable for a recreational tricycle

[0041] like Figure 5 As shown, this embodiment provides a recreational tricycle, which includes a frame 6, wheels, a seat, pedals, and the aforementioned wear-resistant brake lever assembly mounted on the frame 6.

[0042] Preferably, the frame 6 is an integral welded structure made of high-strength steel, with the front fork and handlebars connected at the front end and symmetrical rear wheels at the rear.

[0043] The foot brake lever assembly 1 is mounted on the front of the frame 6, with one side of its foot brake lever bracket 11 fixed to the frame 6 and the other side having a locking bolt 111. The rear brake linkage assembly 2 is mounted on the rear of the frame 6;

[0044] By pressing the foot brake lever, the foot brake lever shaft 12 drives the rear brake linkage assembly 2 to brake the rear wheels. The operation is simple and the braking effect is reliable.

[0045] The wear-resistant bushings 31 and 32 ensure smooth braking action and minimal wear, significantly reducing maintenance frequency and improving the safety and service life of the entire vehicle.

[0046] Preferably, the foot brake lever shaft 12 is made of anodized aluminum alloy to reduce weight and enhance corrosion resistance; the rear brake linkage shaft 21 is made of stainless steel to improve structural strength.

[0047] Bushings 31 and 32 are both made of high-temperature resistant PA46+PTFE material, suitable for high-temperature riding environments.

[0048] When the user depresses the foot brake lever assembly 1, the foot brake lever shaft 12 rotates around the foot brake lever bracket 11, reducing friction and noise through the wear-resistant bushing 31. The foot brake lever assembly 1 drives the rear wheel brake via the rear brake linkage assembly 2, and the linked braking system ensures rapid response and efficient braking. The protective and lubricating design of the wear-resistant bushing enhances the reliability and durability of the entire vehicle.
