Description

Technical Field

[0001] This utility model relates to the field of bicycle pedal technology, and in particular to an anti-slip pedal structure for power-assisted bicycle pedals. Background Technology

[0002] In the use of electric bicycles, the pedals, as a key connecting component between the rider's power output and the vehicle's power transmission, directly affect the safety and stability of riding due to their anti-slip performance. Especially in rainy weather, on slippery roads, or when the rider's shoes are wet, if the pedals do not have good anti-slip properties, it is very easy for the foot to slip relative to the pedals. This not only affects the efficiency of power output but may also lead to the dangerous situation of the rider's foot slipping off the pedals, posing a serious threat to riding safety. At the same time, for long-distance riding or riding with a heavy load, the pedals' stable restraint on the foot is also crucial, reducing physical exertion during riding and improving the riding experience.

[0003] The existing pedals of electric bicycles cannot be adapted to different foot sizes due to their limiting frames. For riders with larger or smaller feet, either the feet are excessively squeezed by the frame, affecting comfort, or the frame cannot effectively limit the feet, further exacerbating the problem of foot wobbling. At the same time, some pedal anti-slip components are fixed in design, making them difficult to replace after wear, requiring the entire pedal to be replaced, which increases the cost of use. Therefore, these problems need to be improved. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-slip pedal structure for a power-assisted bicycle pedal, comprising a foot pedal, wherein a fixed cylinder is fixedly connected to the middle of both ends of the foot pedal, a bracket is rotatably mounted on the fixed cylinder, two docking grooves are symmetrically opened on one side of the bracket, a locking buckle is hinged at each docking groove, an elastic band is installed between the two docking grooves, and a frame is installed on the top and bottom surfaces of the foot pedal, wherein multiple reinforcing plates are fixedly connected in a star-shaped pattern within the frame.

[0006] Preferably, the elastic band has a first threaded hole at the buckle, and both the buckle and the mating groove have mating holes coaxial with the first threaded hole. A fixing bolt is screwed into the mating hole and the first threaded hole.

[0007] Preferably, the frame and the top surface of the reinforcing plate are provided with a plurality of anti-slip posts evenly distributed, and each anti-slip post is screwed with a cross screw.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4 This utility model discloses an anti-slip pedal structure for a power-assisted bicycle pedal, comprising a pedal 1, with a fixing cylinder 11 fixedly connected to the middle of both ends of the pedal 1, and a bracket 2 rotatably mounted on the fixing cylinder 11. Two docking slots are symmetrically opened on one side of the bracket 2, and a locking buckle 6 is hinged at each docking slot. An elastic band 5 is installed between the two docking slots. A frame 3 is installed on the top and bottom surfaces of the pedal 1, and multiple reinforcing plates are fixedly connected in a star-shaped pattern inside the frame 3. Both the bracket 2 and the pedal 1 are made of aluminum alloy. Using aluminum alloy for the bracket 2 and the pedal 1 can reduce weight while ensuring structural strength and improve riding ease. This section of the structure, through the inclusion of an elastic band 5 and a frame 3, provides a foundation for adapting to different foot sizes and enhancing structural stability, thus improving the practicality of the pedal. The elastic band 5 has a first threaded hole 8 at the locking buckle 6. Both the locking buckle 6 and the mating groove have mating holes coaxial with the first threaded hole 8, and fixing bolts 7 are screwed into the mating holes and the first threaded hole 8. The elastic band 5 is made of natural rubber, which provides excellent elasticity and wear resistance, better adapting to different foot shapes and extending its service life. The fixing bolts 7 allow for the detachable fixing of the elastic band 5, facilitating adjustment and improving adaptability to different foot sizes. Multiple anti-slip posts 4 are evenly distributed on the top surface of the frame 3 and the reinforcing plate, each with a cross-head screw screwed into it. The anti-slip posts 4 are made of nitrile rubber, which provides excellent anti-slip performance and oil resistance, effectively enhancing the friction between the pedal and the shoe sole. This structure allows for the detachable installation of the anti-slip post 4 using Phillips head screws, facilitating individual replacement of the anti-slip post 4 after wear and reducing operating costs.

[0020] In this invention, a connecting post 12 is inserted through two fixed cylinders 11. A limiting fixing sleeve is fitted onto one end of the connecting post 12, and a slot 13 is formed on the outer wall of the other end of the connecting post 12. The limiting fixing sleeve is made of stainless steel, which improves the stability and corrosion resistance of the connection and ensures smooth pedal rotation. This structure, through the cooperation of the connecting post 12 and the limiting fixing sleeve, enables flexible rotation of the pedal 1, improving the smoothness of power generation during riding. An installation groove is formed on the outer wall of one end of each of the two fixed cylinders 11, and a chuck 9 is inserted into the installation groove. A corresponding insert piece is fixedly connected to the middle of the chuck 9 to the slot 13. The insert piece is made of spring steel, which has good elasticity and toughness and can be tightly inserted into the slot 13 to ensure the stability of the connection. This structure, through the cooperation of the insert and the slot 13, achieves rapid positioning and fixation of the connecting post 12 and the fixing cylinder 11, improving assembly efficiency. A second threaded hole is provided at the axis of the connecting post 12, and a corresponding through hole is provided in the middle of the insert. A mounting bolt 10 is screwed into the through hole and the second threaded hole. The mounting bolt 10 is made of high-strength carbon steel, which provides sufficient locking force to prevent loosening and ensure safety during pedal use. This structure further reinforces the connecting post 12 and the chuck 9 with the mounting bolt 10, improving the overall structural stability and preventing parts from falling off during riding.

[0021] Working principle: When using this utility model, the foot is placed on the foot pedal 1, and the locking buckle 6 and the fixing bolt 7 cooperate to fix the elastic band 5. The elastic band 5 itself is elastic and can adapt to different foot sizes, achieving a stable constraint on the foot. The frame 3 on the top and bottom surfaces of the foot pedal 1 and the cross-shaped reinforcing plate enhance the overall structural strength and ensure the stability of the foot pedal under load. The anti-slip posts 4 on the frame 3 and the reinforcing plate increase the friction with the sole of the shoe and play an anti-slip role. When the anti-slip posts 4 are worn, they can be removed and replaced individually with cross screws. The fixing cylinder 11 cooperates with the bracket 2 and the connecting post 12 to allow the foot pedal 1 to rotate flexibly to adapt to the force requirements during riding. The connecting post 12 is stably connected to the fixing cylinder 11 through the limiting fixing sleeve, the slot 13, the chuck 9 and the mounting bolt 10 to ensure the stability of the pedal during rotation. At this point, the device is in use.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
