Description

Technical Field

[0001] This invention relates to the field of pedal technology, and in particular to a pedal structure with a brake. Background Technology

[0002] A bicycle, also known as a pedal bike or cyclist, is a small, two-wheeled land vehicle. Riders power their bikes by pedaling, making them a green and environmentally friendly mode of transportation, as well as a beneficial form of exercise. Due to these advantages, bicycles remain a mainstream mode of transportation.

[0003] In existing technology, bicycles typically only have brake levers on the handlebars. Riders squeeze the brake levers to tighten the brake cable, causing the brake pads on both sides of the wheel to come closer together and gradually lock onto the wheel to achieve braking. However, when the brake levers malfunction or a rider experiences finger injury or other special circumstances, they cannot brake by squeezing the brake levers with their fingers. This is inconvenient, dangerous, and lacks safety. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the low safety performance of bicycles in the prior art by providing a pedal structure with brakes that improves safety performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A foot pedal structure with a brake includes a pedal shaft, a brake module, and a foot pedal. The brake module is located on one side of the pedal shaft, and the foot pedal is located on the opposite side of the pedal shaft. The brake module is located at one end of the pedal shaft and is perpendicular to it. The foot pedal is rotatably connected to the other end of the pedal shaft and is perpendicular to it. One end of the pedal shaft is rotatably connected relative to the brake module under the drive of the foot pedal. The foot pedal has a foot cover that is horizontally slidably connected to the foot pedal along the vertical direction of the pedal shaft. The pedal shaft has a tensioning assembly parallel to the pedal shaft. The tensioning assembly is horizontally slidably connected to the pedal shaft along the vertical direction of the pedal shaft. The tensioning assembly rotates synchronously with the pedal shaft, and one end of it is slidably connected to the brake module along the direction of rotation. A connector is fixed to the side of the other end of the tensioning assembly. One side of the foot cover is close to the pedal shaft, and the opposite side of the foot cover is away from the pedal shaft. The side of the foot cover close to the pedal shaft has a mating assembly that matches the connector. The foot cover is detachably connected to the tensioning assembly through the mating assembly and the connector.

[0007] The brake module is located on one side of the pedal shaft, and the foot pedal is located on the opposite side of the pedal shaft. The brake module is located at one end of the pedal shaft and is perpendicular to the pedal shaft. The foot pedal is rotatably connected to the other end of the pedal shaft and is perpendicular to the pedal shaft. One end of the pedal shaft is rotatably connected to the brake module under the drive of the foot pedal. The foot pedal is provided with a foot cover, which is horizontally slidably connected to the foot pedal along the vertical direction of the pedal shaft. The pedal shaft is provided with a tensioning assembly parallel to the pedal shaft, which is horizontally slidably connected to the pedal shaft along the vertical direction of the pedal shaft. The tensioning assembly rotates synchronously with the pedal shaft, and one end of it is slidably connected to the brake module along the direction of rotation. A connector is fixed to the side of the other end of the tensioning assembly. One side of the foot cover is close to the pedal shaft, and the opposite side of the foot cover is away from the pedal shaft. The side of the foot cover close to the pedal shaft is provided with a mating assembly that matches the connector. The foot cover is detachably connected to the tensioning assembly through the mating assembly and the connector. When braking, the rider's foot moves the pedal to a low position, then the foot cover slides horizontally relative to the pedal and gradually approaches the pedal axle until the connector matches and connects with the mating assembly. Then, the foot again moves the foot cover horizontally relative to the pedal and gradually moves away from the pedal axle. At this time, the foot cover, fixed by the mating assembly and the connector, moves the brake module synchronously away from the vehicle body through the tensioning assembly. The brake module gradually grips the wheel, thus achieving the braking function. This avoids the situation where the rider cannot brake in special circumstances, thereby improving safety performance.

[0008] Preferably, the top of the pedal axle is provided with a connecting block perpendicular to it. The sidewall of the connecting block is fixedly connected to the pedal axle and forms an integral part. One end of the connecting block is provided with a groove with a circular cross-section. The other end of the connecting block and the foot pedal are both located on the same side of the pedal axle. The corresponding other side of the pedal axle is provided with a clearance groove that matches the tensioning component. The bottom sidewall of the groove is provided with a rectangular opening that communicates with the clearance groove. One end of the tensioning component passes through the rectangular opening and is horizontally slidably connected to the groove. The brake module passes through the opening end of the groove and is located inside the groove and is slidably connected to the tensioning component. The other end of the tensioning component is located outside the clearance groove. The design of the clearance groove facilitates the tensioning component to slide horizontally along the length of the rectangular opening under the drive of the foot strap, so that when the brake module moves away from the vehicle body, it is gradually tightened and grips the wheel to achieve the braking function. On the other hand, in the riding state, the tensioning component is stored inside the pedal axle, which is aesthetically pleasing and convenient for riding.

[0009] Preferably, the tensioning assembly includes a pull rod and a slider that matches the groove. One end of the pull rod passes through a rectangular opening and is fixedly connected to the side wall of the slider. The pull rod is horizontally slidably connected to the groove via the slider. One end of the slider is close to the bottom of the groove, and the other end is away from the bottom of the groove. The end of the slider away from the bottom of the groove is provided with an annular groove that matches the brake module. The slider is slidably connected to the brake module via the annular groove. The other end of the pull rod is vertically provided with a connecting rod. One end of the connecting rod is located inside the clearance groove and is fixedly connected to the pull rod. The other end of the connecting rod is located outside the clearance groove and is fixedly connected to the connector. When the bicycle is being ridden, the connector and the docking assembly are separated, allowing the pedals to rotate while simultaneously rotating the pedal shaft around one end. Due to the rectangular opening, the tensioning assembly rotates synchronously with the pedal shaft. Meanwhile, since one end of the brake module is fixed to the bicycle frame, and the other end is slidably connected to the slider via an annular groove, the annular groove on the slider facilitates the simultaneous rotation of the pedal shaft and the tensioning assembly, ensuring normal riding. When braking, the foot strap, connected and fixed to the connector via the docking assembly, sequentially moves the brake module synchronously away from the bicycle frame via the connecting rod, pull rod, and slider. The brake module gradually tightens, gripping the wheel and achieving the braking function. This prevents riders from being unable to brake in special circumstances, thus improving safety.

[0010] Preferably, the connecting block and the foot pedal have a wheel axle coaxial with the annular groove at one end of the foot pedal axle. The wheel axle is detachably and fixedly connected to the connecting block and passes through the center of the groove. The center of the slider has a circular hole matching the wheel axle, and the slider is fitted onto the wheel axle through the circular hole. The brake module is located on the side of the wheel axle. One end of the wheel axle is fixedly connected to the connecting block, and the other end of the wheel axle is fixedly connected to a sprocket on the vehicle body, so that the foot pedal axle drives the sprocket to rotate, thereby driving the wheel to rotate and propelling the vehicle forward.

[0011] Preferably, the annular groove has a T-shaped cross-section, and several balls evenly distributed along its circumference are embedded on both sides of the annular groove. The brake module includes a brake cable and a second slider. One end of the second slider is slidably connected to the annular groove via the balls, and the brake cable passes through the opening end of the groove and is fixedly connected to the other end of the second slider. The T-shaped cross-section of the annular groove facilitates braking. When the foot is fixed to the connector via the docking assembly, the brake cable moves synchronously away from the vehicle body through the connecting rod, pull rod, and first slider in sequence, thereby tightening the brake cable and gradually gripping the wheel.

[0012] Preferably, a straight rod parallel to the depth direction of the groove is fixed to the other side wall of the second slider. Several limiting sleeves matching the brake cable are fixed to the straight rod, and these limiting sleeves are evenly distributed along the length of the straight rod. The brake cable is horizontally slidably connected to the limiting sleeves. The design of the limiting sleeves facilitates straightening the brake cable and aligning it parallel to the wheel axle, preventing the brake cable from twisting, extending its service life, and ensuring smooth rotation of the pedal axle.

[0013] Preferably, the docking assembly includes a linear actuator, a gear, and a rack meshing with the gear. The linear actuator is detachably connected to the side wall of the foot cover, and the telescopic end of the linear actuator is fixedly connected to the rack. The gear is rotatably connected to the side wall of the foot cover under the drive of the linear actuator. The gear has a circular rotating cavity inside. One side of the gear is close to the foot cover, and the corresponding other side of the gear is away from the foot cover. The side of the gear away from the foot cover has a rectangular hole communicating with the rotating cavity. The connector is rectangular in shape and matches the rectangular hole. A proximity switch corresponding to the rectangular hole is detachably installed in the rotating cavity. The bicycle frame is equipped with a battery and a control system. The battery is electrically connected to a linear actuator and a proximity switch to provide power. When the connector is matched with the docking assembly, the foot moves the foot sleeve horizontally relative to the pedal and gradually approaches the connector. When the connector is inserted into the rotating cavity through the rectangular hole, the proximity switch sends a signal to the control system, which then controls the linear actuator to operate, causing the rack to slide and the gear to rotate through a certain angle, thus confining the connector within the rotating cavity. This allows the foot sleeve to move horizontally in the opposite direction, sequentially moving the brake cable through the connecting rod, pull rod, and slider to achieve the braking function. When it is necessary to release the brake, a reset switch can be installed at any point on the bicycle frame that can be reached by a hand or knee. The reset switch controls the linear actuator to operate again, driving the gear to reset, so that the connector is aligned with the rectangular hole again, allowing the gear to separate from the connector.

[0014] Preferably, the foot pedal is provided with a sliding groove, and the foot cover is horizontally slidably connected to the sliding groove. Two springs are provided within the sliding groove, one spring located on the left side of the foot cover, and the other spring located between the foot cover and the pedal axle, on the right side of the foot cover. The sliding groove is elastically connected to the left and right sides of the sliding groove respectively by the two springs, and a gap is formed between the rectangular hole and the connector. During riding, the rectangular hole on the foot cover maintains a certain gap with the connector under the action of the springs, facilitating the foot pedal to drive the pedal axle to rotate.

[0015] Preferably, the foot cover has cover plates on both the left and right sides covering the sliding groove. The cover plates are fixedly connected to the side walls of the foot cover and in contact with the surface of the foot pedal. The linear actuator and the rack are both located on the cover plates, and the rack is slidably connected to the cover plates. The cover plates help prevent dust from entering the sliding groove, ensure the smoothness of the foot cover during sliding, and provide some support for the rack and linear actuator, improving the stability and safety of the structure.

[0016] Preferably, a pivot is fixed on the side wall of the foot pedal, and a bearing that matches the pivot is provided on the pedal pivot. The foot pedal is rotatably connected to the pedal pivot through the pivot and the bearing matching the pivot.

[0017] The beneficial effects of this invention are: the braking function is achieved through the foot pedal, avoiding the phenomenon that the rider cannot brake in special circumstances, thus improving safety performance; the design of the limiting sleeve makes it easy to straighten the brake cable and make it parallel to the wheel axle, preventing the brake cable from twisting, extending the service life of the brake cable, and ensuring the smooth rotation of the pedal axle; the cover plate helps to prevent dust from entering the sliding groove, helps to ensure the smoothness of the foot cover sliding, and at the same time provides a certain support for the rack and linear actuator, improving the stability and safety of the structure.

[0028] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the tensioning assembly 5 includes a pull rod 12 and a slider 13 that matches the groove 9.

The center of the slider 13 is provided with a round hole 17 that matches the wheel shaft 16. The slider 13 is sleeved on the wheel shaft 16 through the round hole 17. The brake module 2 is located on the side of the wheel shaft 16.

[0030] like Figure 4 As shown, the cross-sectional shape of the annular groove 14 is T-shaped. Several balls 18 are embedded on both sides of the annular groove 14 and are evenly distributed around its circumference. The brake module 2 includes a brake line 19 and a slider 20. One end of the slider 20 is slidably connected to the annular groove 14 through the balls 18. The brake line 19 passes through the opening end of the groove 9 and is fixedly connected to the other end of the slider 20.

[0031] like Figure 4 and Figure 6As shown, a straight rod 21 parallel to the depth direction of the groove 9 is fixed on the other side wall of the slider 20. Several limiting sleeves 22 that match the brake line 19 are fixed on the straight rod 21. The several limiting sleeves 22 are evenly distributed along the length direction of the straight rod 21. The brake line 19 is horizontally slidably connected to the limiting sleeves 22.

[0032] like Figure 1 , Figure 3 and Figure 5 As shown, the docking assembly 7 includes a linear actuator 23, a gear 24, and a rack 25 meshing with the gear 24. The linear actuator 23 is detachably connected to the side wall of the foot cover 4. The telescopic end of the linear actuator 23 is fixedly connected to the rack 25. The gear 24 is rotatably connected to the side wall of the foot cover 4 under the drive of the linear actuator 23. The gear 24 has a circular rotating cavity 26. One side of the gear 24 is close to the foot cover 4, and the corresponding other side of the gear 24 is away from the foot cover 4. The side of the gear 24 away from the foot cover 4 has a rectangular hole 27 that communicates with the rotating cavity 26. The connector 6 is rectangular in shape and matches the rectangular hole 27. A proximity switch 28 corresponding to the rectangular hole 27 is detachably installed in the rotating cavity 26.

[0033] like Figure 2 and Figure 5 As shown, the foot pedal 3 has a sliding groove 29, and the foot cover 4 is horizontally slidably connected to the sliding groove 29. Two springs 30 are installed inside the sliding groove 29, one spring 30 located on the left side of the foot cover 4, and the other spring 30 located between the foot cover 4 and the pedal shaft 1, on the right side of the foot cover 4. The sliding groove 29 is elastically connected to the left and right sides of the foot cover 29 respectively through the two springs 30. A gap 31 is formed between the rectangular hole 27 and the connector 6. Cover plates 32 covering the sliding groove 29 are provided on both the left and right sides of the foot cover 4. The cover plates 32 are fixedly connected to the side walls of the foot cover 4 and contact the surface of the foot pedal 3. The linear actuator 23 and the rack 25 are both located on the cover plates 32, and the rack 25 is slidably connected to the cover plates 32.

The foot pedal 3 is rotatably connected to the pedal shaft 1 through the matching of the rotating shaft 33 and the bearing 34.

[0034] When the bicycle is in riding mode, the connector 6 and the docking assembly 7 are separated, allowing the pedal 3 to rotate while simultaneously driving the pedal shaft 1 to rotate around one end of the pedal shaft 1. The bicycle frame is equipped with a battery and a control system. The battery is electrically connected to the linear actuator 23 and the proximity switch 28 to provide power. When braking, the rider's foot lowers the pedal 3, causing the foot cover 4 to slide horizontally relative to the pedal 3 and gradually approach the connector 6. When the connector 6 is inserted into the rotating cavity 26 through the rectangular hole 27, the proximity switch 28 sends a signal to the control system, which then controls the linear actuator. When the linear actuator 23 operates, it drives the rack 25 to slide, thereby driving the gear 24 to rotate through a certain angle, so that the connector 6 is confined within the rotating cavity 26. This allows the foot sleeve 4 to move horizontally in the opposite direction, sequentially driving the brake cable 19 to move synchronously through the connecting rod 15, the pull rod 12, and the slider 13, thus achieving the braking function. When it is necessary to release the brake, a reset switch can be set at any point on the vehicle body that can be touched by a hand or knee. The reset switch controls the linear actuator 23 to work again, driving the gear 24 to reset, so that the connector 6 is aligned with the rectangular hole 27 again, so that the gear 24 and the connector 6 can be separated.
