Description

Technical Field

[0001] This utility model relates to the technical field of retractable pedal structures, and more particularly to a retractable pedal structure for electric bicycles. Background Technology

[0002] As a convenient means of short-distance transportation, the pedal structure of electric bicycles is an important component that combines human riding and emergency driving. Traditional electric bicycles mostly have a fixed pedal design that protrudes from both sides of the vehicle (the extension length is usually 15-20cm). When parked or passing through narrow spaces (such as corridors and alleys), they are prone to collisions with surrounding objects (collision rate exceeds 30%), resulting in pedal deformation or vehicle body scratches (increasing the repair rate by 20%-25%). Existing retractable pedal structures for electric bicycles have several drawbacks. Firstly, the folding mechanisms of some pedals are complex, requiring manual unlocking and rotation (each operation takes 10-15 seconds). Secondly, some components remain exposed after folding (exposed length exceeding 5cm), failing to completely solve the space occupation problem. Thirdly, the limiting reliability at the folding joints is insufficient, leading to loosening on bumpy roads (loosening rate exceeding 15%), causing abnormal noise during riding (noise exceeding 60 decibels), and even affecting pedaling power (power transmission efficiency decreases by 10%-15%). Therefore, these technical problems need to be addressed. Utility Model Content

[0014] 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.

[0015] Example: See Figures 1 to 5 The present invention relates to a retractable pedal structure for electric bicycles, comprising a fixed block 1, a pedal storage mechanism mounted on the fixed block 1, a telescopic rod 2 fixedly connected to the upper end of the fixed block 1, the telescopic rod 2 being sleeved inside an adjusting rod 3, and a length adjustment mechanism installed between the telescopic rod 2 and the adjusting rod 3. A hinge block is fixedly connected to the adjusting rod 3, and the hinge block is hinged to a connecting block 7 on the vehicle body. A positioning mechanism is installed on the outer side of the hinge block. Both the positioning mechanism and the pedal storage mechanism employ limit mechanisms. Through the fixed block 1, pedal storage mechanism, telescopic rod 2, adjusting rod 3, length adjustment mechanism, hinge block, connecting block 7, positioning mechanism, and limit mechanism, the pedal can be easily stored, its length adjusted, and its position fixed. The limiting mechanism includes limiting blocks 5 distributed on the positioning block 6 and the fixing block 1. One end of the limiting block 5 is fixedly connected to a connecting rod. A second telescopic spring 11 is sleeved on the connecting rod, and a locking block 10 is fixedly connected to one end of the connecting rod. Through the limiting blocks 5, connecting rod, second telescopic spring 11 and locking block 10 on the positioning block 6 and the fixing block 1, it is convenient to limit and fix the relevant components. The positioning mechanism includes a positioning block 6 sleeved on the outside of the hinge block. A positioning hole is opened on one side of the positioning block 6. The positioning hole extends through the positioning block 6 to the side of the hinge block, and a limiting mechanism is locked in the positioning hole. Through the positioning block 6, positioning hole and limiting mechanism on the outside of the hinge block, it is convenient to fix the hinge angle between the foot pedal structure and the vehicle body.

[0016] In this utility model, the foot pedal storage mechanism includes a horizontal opening on one side of the fixed block 1, through which a foot pedal 4 is horizontally inserted. One end of the foot pedal 4 has a rotating hole that vertically penetrates the fixed block 1. A limiting mechanism is installed in the rotating hole between the fixed block 1 and the foot pedal 4. The opening on the fixed block 1, the foot pedal 4, the rotating hole, and the limiting mechanism facilitate the storage and unfolding of the foot pedal 4. The length adjustment mechanism includes a positioning groove 8 on the adjusting rod 3. A positioning rod is fixedly connected to the telescopic rod 2, which is movably sleeved inside the adjusting rod 3, within the positioning groove 8. A first telescopic spring 9 is installed between the adjusting rod 3 and the telescopic rod 2. The length adjustment mechanism allows for the storage and unfolding of the foot pedal 4. The positioning groove 8 on rod 3, the positioning rod on telescopic rod 2, and the first telescopic spring 9 facilitate adjustment of the overall length of the foot pedal structure; one end of the positioning hole is attached to the limiting block 5 on the positioning block 6, and the locking block 10 on the connecting rod at one end of the limiting block 5 abuts against the positioning hole of the hinge block. Through the positioning hole on the positioning block 6, the limiting block 5, and the locking block 10, it is easy to lock the relative angle between the hinge block and the positioning block 6; the limiting block 5 is tightly fitted at the rotating hole at the lower end of the fixing block 1, and the locking block 10 on the connecting rod at one end of the limiting block 5 abuts against the rotating hole at one end of the foot pedal 4. Through the rotating hole at the lower end of the fixing block 1, the limiting block 5, and the locking block 10, it is easy to fix the unfolded and retracted state of the foot pedal 4.

[0017] Working principle: When using this utility model, firstly, by pulling down the limiting block 5 at the lower end of the rotating hole of the fixing block 1, the connecting rod moves through the limiting block 5, simultaneously compressing the second telescopic spring 11. Then, the locking block 10 exits from the rotating hole at one end of the foot pedal 4, releasing the limiting on the foot pedal 4, thereby pulling the foot pedal 4 out from the horizontal opening of the fixing block 1. Then, rotate it around the rotating hole to a horizontal state. At this moment, the limiting block 5 is released, and under the elastic force of the second telescopic spring 11, the locking block 10 abuts against the rotating hole again. At this time, the foot pedal 4 is locked in the horizontal use position, thus realizing the unfolding and storage of the foot pedal 4. Then, if it is necessary to adjust the foot pedal... When adjusting the overall length of the structure, the positioning rod on the telescopic rod 2 is disengaged from the positioning groove 8 of the adjusting rod 3. At this time, the elastic force of the first telescopic spring 9 is released or further compressed, pushing or pulling the telescopic rod 2 to slide inside the adjusting rod 3 until the appropriate length is achieved. Simultaneously, the positioning rod moves into the corresponding positioning groove 8. Under the action of the first telescopic spring 9, the length of the telescopic rod 2 and the adjusting rod 3 is fixed, ensuring the stability of the pedal structure length. At the same time, the locking can be released by pulling out the limiting block 5 on the positioning block 6, rotating the pedal structure to a position close to the vehicle body, and releasing the limiting block 5 to complete the angle fixation, thereby enabling pedal riding of the electric bicycle.

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.
