Description

Technical Field

[0001] The utility model belongs to the technical field of brake pedals, and in particular relates to a labor-saving tricycle brake pedal. Background Art

[0002] In the evolution of transportation, tricycles are widely used in cities, rural areas and specific working environments as an economical and practical means of short-distance transportation. However, with the development of society and the aging of the population, the design defects of traditional tricycles have gradually emerged, especially in the design of the brake system, which has problems that cannot be ignored.

[0003] The brake pedal of a traditional tricycle often adopts a direct mechanical connection, that is, the pedal is directly connected to the brake lever, and braking is achieved by stepping on the pedal to pull the brake lever. Although this design is simple in structure, it exposes many disadvantages during actual use. First, due to the direct connection, the force required to step on the pedal is often large. For users with weaker physical strength, such as the elderly, the disabled, or workers who drive for a long time, long-term stepping will cause leg fatigue and may even cause physical discomfort. Secondly, the brake pedal's pedaling travel and force control are not precise enough, which can easily lead to excessive or slow braking, affecting driving safety. Utility Model Content

[0004] The utility model aims to provide a labor-saving tricycle brake pedal to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A labor-saving tricycle brake pedal, comprising:

[0007] A fixed plate, a pedal is movably installed on one side of the fixed plate, connecting ears are symmetrically installed on both sides of the fixed plate, a rotating shaft is fixedly installed on one side of the fixed plate close to the pedal, the pedal is movably sleeved on the outside of the rotating shaft through an opening, two torsion springs are arranged on the outside of the rotating shaft, and the two ends of the torsion spring are respectively fixedly connected to the fixed plate and the pedal.

[0008] Preferably, a connecting piece is fixedly mounted on one side of the fixing plate, a special-shaped rod is hinged inside the connecting piece, and a connecting hole is opened on one side of the special-shaped rod.

[0009] Preferably, an L-shaped plate is fixedly installed on one side of the inner part of the pedal, and a connecting rod is hinged between the L-shaped plate and the special-shaped rod.

[0010] Preferably, the fixing plate and the pedal are both made of metal.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The utility model converts a smaller pedaling force into a larger brake rod pulling force through the connecting rod transmission principle. This design not only reduces the force required for pedaling, but also makes the braking action more sensitive and precise, achieving a smooth and safe braking effect. By introducing a torsion spring auxiliary reset mechanism, the pedal can automatically store elastic potential energy during the pedaling process and release the energy when the pedal is released, thereby assisting the pedal to reset quickly. This design greatly reduces the burden on the user's feet and makes the pedaling action easier and more labor-saving. At the same time, due to the buffering effect of the torsion spring, the impact force during the pedaling process is effectively alleviated, thereby improving the user's comfort. The brake pedal of this application also pays attention to detail design, such as anti-slip treatment of the pedal surface and anti-rust treatment of the connecting rod, which further enhances the user's experience.

[0013] (2) The utility model significantly improves the safety performance of the tricycle by optimizing the structural design of the brake pedal. Firstly, since the pedaling force is reduced and the control is precise, the user can more easily grasp the timing and force of braking during use, avoiding the safety hazards caused by braking too hard or too slowly. Especially in emergency situations, the user can quickly and accurately complete the braking action, effectively shorten the braking distance, and reduce the risk of accidents. In addition, the brake pedal of the present application also has good durability and stability. By selecting high-quality materials and fine processing technology, the reliability and durability of the brake pedal are ensured. At the same time, the reasonable structural design enables the brake pedal to maintain stable performance during long-term use, providing strong protection for the user's driving safety.

[0014] (3) The utility model not only solves the problems existing in traditional brake pedals, but also promotes the innovative development of the tricycle industry. The innovative design concept and advanced technology application of this application provide new ideas and methods for the improvement of the tricycle brake system. By introducing mechanical components and transmission mechanisms such as torsion springs and connecting rods, the brake pedal has the functions of labor-saving operation, precise control and automatic reset, which provides a useful reference for the optimization design of the tricycle brake system. The application of this application will promote the transformation, upgrading and high-quality development of the tricycle industry. With the improvement of people's living standards and the diversification of transportation needs, users have higher and higher performance requirements for short-distance transportation tools such as tricycles. The labor-saving tricycle brake pedal of this application, with its excellent user experience and safety performance, will win the favor and trust of more users and promote the tricycle industry to develop in a more comfortable and safe direction.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1:

[0022] See also Figure 1 - Figure 4 As shown, a labor-saving tricycle brake pedal comprises:

[0023] A fixed plate 1, a pedal 2 is movably installed on one side of the fixed plate 1, connecting ears 3 are symmetrically installed on both sides of the fixed plate 1, a rotating shaft 4 is fixedly installed on one side of the fixed plate 1 close to the pedal 2, the pedal 2 is movably sleeved on the outside of the rotating shaft 4 through an opening, two torsion springs 5 ​​are arranged on the outside of the rotating shaft 4, and the two ends of the torsion spring 5 are fixedly connected to the fixed plate 1 and the pedal 2 respectively.

[0024] Specifically, a connecting piece 6 is fixedly installed on one side of the fixed plate 1, a special-shaped rod 7 is hinged inside the connecting piece 6, and a connecting hole 8 is opened on one side of the special-shaped rod 7. An L-shaped plate 9 is fixedly installed on one side of the pedal 2, and a connecting rod 10 is hinged between the L-shaped plate 9 and the special-shaped rod 7. The fixed plate 1 and the pedal 2 are both made of metal.

[0025] As can be seen from the above, the fixing plate 1 is used to be installed in the foot placement area of ​​the tricycle. The inside of the connecting ear 3 is provided with holes for installing bolts and other structures, which is convenient for installing the fixing plate 1 on the tricycle. The rotating shaft 4 is used to install the pedal 2. The torsion spring 5 can drive the pedal 2 to complete the reset. When the pedal 2 is stepped on, the torsion spring 5 is stressed. When the pedal 2 is released, the torsion spring 5 drives the pedal 2 to complete the reset. The special-shaped rod 7 is connected to the brake rod of the tricycle through the connecting hole 8. The connecting rod 10 connects the special-shaped rod 7 with the L-shaped plate 9, so that when the pedal 2 is stepped on, the special-shaped rod 7 can be driven to swing, thereby pulling the brake rod of the tricycle to move, thereby achieving a braking effect.

[0026] When in use, when the pedal 2 is stepped on, the L-shaped plate 9 applies pressure downward and drives the special-shaped rod 7 to swing through the connecting rod 10. The special-shaped rod 7 pulls the brake rod of the tricycle. At this time, the torsion spring 5 is in a stressed state, and the tricycle starts to brake. Then, the pedal 2 is released, the torsion spring 5 drives the pedal 2 to reset, and the special-shaped rod 7 stops pulling the brake rod of the tricycle. At this time, the tricycle can drive normally.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
