Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, and in particular to a quick-release structure for bicycle pedals. Background Technology

[0002] Pedals are the components in a bicycle's drivetrain that come into direct contact with the rider's feet. They efficiently convert the rider's pedaling force into rotational force that propels the bicycle forward via the crank and chainring. To meet the convenience and functionality requirements of modern cyclists, quick-release pedals were developed, allowing riders to quickly remove or reinstall the pedals from the crank without using any tools.

[0003] Currently, there are various quick-release pedals with different structures on the market, but most of these quick-release pedals place the unlocking control on the side of the crank facing the pedal. During normal riding, the pedal can easily be unlocked due to accidental contact with the unlocking control, resulting in low safety. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a bicycle pedal quick-release structure with high safety.

[0005] The present invention adopts the following technical solution:

[0006] This utility model provides a quick-release structure for bicycle pedals, including a crank, a pedal, a pedal sleeve, and an unlocking control component. The pedal sleeve is installed on the crank, the pedal passes through the pedal sleeve, and the unlocking control component is rotatably fitted on the pedal sleeve and located on the side of the crank away from the pedal. The pedal sleeve accommodates a limiting component that can move radially, and the unlocking control component can rotate to control the limiting component to lock and unlock the pedal.

[0007] Preferably, the bottom end of the limiting member is located in the annular groove of the foot pedal and can move away from the annular groove with the axial movement of the foot pedal. The unlocking control member is continuously provided with a locking part and a clearance part. When the unlocking control member is rotated so that the locking part reaches the limiting member, the locking part locks the limiting member in the annular groove. When the unlocking control member is rotated so that the clearance part reaches the limiting member, a gap is formed between the clearance part and the limiting member that can accommodate the limiting member.

[0008] Preferably, the groove of the annular groove has a minor arc shape, the limiting element is a rolling element, and the assembly hole of the unlocking control element is provided with a clearance space. The clearance space gradually expands around the rotation direction of the unlocking control element, with the bottom end of the clearance space being the locking part and the top end being the clearance part.

[0009] Preferably, one end of the pedal sleeve extends radially outward to form a first stop, and the other end of the pedal sleeve passes through a through hole on the crank and is engaged with a second stop. The unlocking control is axially limited between the crank and the second stop.

[0010] Preferably, the end of the foot pedal sleeve is radially concave to form an annular snap-fit ​​groove, and one axial end of the annular snap-fit ​​groove is provided with multiple notches. Multiple locking blocks extend radially from the wall of the sleeve hole on the second baffle. The second baffle is sleeved on the foot pedal sleeve through the locking blocks across the notches, and after rotating the second baffle to make the locking blocks engage with the annular snap-fit ​​groove, the second baffle is engaged with the foot pedal sleeve.

[0011] Preferably, the second baffle is detachably connected to the unlocking control, and the second baffle completely covers the side of the unlocking control away from the crank.

[0012] Preferably, the unlocking control is ring-shaped.

[0013] Preferably, the unlocking control component has multiple weight-reducing holes spaced at equal intervals in a circumferential direction, and each weight-reducing hole is hollowed out along the axial direction.

[0014] Preferably, the unlocking control is connected to the pedal sleeve via a torsion spring. When the torsion spring is in its natural state, the unlocking control controls the limiting element to lock the pedal.

[0015] Preferably, the assembly hole of the unlocking control component is provided with an axially penetrating clearance hole, the shape of which is adapted to the top shape of the limiting component.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model's quick-release bicycle pedal structure allows for locking and unlocking of the pedal by rotating the unlocking control, achieving quick release between the pedal and crank. Furthermore, because the unlocking control is located on the side of the crank furthest from the pedal, it prevents the rider from accidentally touching the unlocking control and unlocking the pedal during riding, thus ensuring a high level of safety.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0032] See Figure 1 and Figure 5 This embodiment provides a quick-release bicycle pedal structure, including a crank 1, a pedal 2, a pedal sleeve 3, and an unlocking control 4. The pedal sleeve 3 is installed on the crank 1, and the pedal 2 passes through the pedal sleeve 3. The unlocking control 4 is rotatably fitted on the pedal sleeve 3 and located on the side of the crank 1 away from the pedal 2. The pedal sleeve 3 accommodates a radially movable limiting member 5. The unlocking control 4 can rotate to control the limiting member 5 to lock and unlock the pedal 2.

[0033] In this embodiment, the quick-release bicycle pedal structure locks and unlocks the pedal 2 by rotating the unlocking control 4, thus achieving quick release between the pedal 2 and the crank 1. Furthermore, since the unlocking control 4 is located on the side of the crank 1 furthest from the pedal 2, it prevents the rider from accidentally touching the unlocking control 4 during riding, thus ensuring a high level of safety.

[0034] Better yet, see Figure 3 The foot pedal 2 includes a foot pedal shaft 202 and a foot pedal 203. One end of the foot pedal shaft 202 is rotatably connected to the foot pedal 203, and the other end of the foot pedal shaft 202 is inserted into the foot pedal sleeve 3.

[0035] Better yet, see Figure 3 In this embodiment, the diameter of the foot pedal shaft 202 at the end away from the foot pedal 203 is larger than the diameter at the end closer to the foot pedal 203, so that the end of the foot pedal shaft 202 away from the foot pedal 203 (crank end) has sufficient bending strength and rigidity to prevent the foot pedal shaft 202 from deforming or breaking.

[0036] Better yet, see Figure 3 In this embodiment, the foot pedal 203 is provided with positioning protrusions 204 at intervals on the outer edge of the top and bottom surfaces to increase the friction between the foot pedal 203 and the rider's shoe sole, making riding easier.

[0037] Preferably, see Figure 1 , Figure 3, Figure 5 and Figure 7 The bottom end of the limiting member 5 is located in the annular groove 201 of the foot pedal 2 and can move away from the annular groove 201 with the axial movement of the foot pedal 2. The unlocking control member 4 is continuously provided with a locking part 401 and a clearance part 402. When the unlocking control member 4 is rotated so that the locking part 401 reaches the limiting member 5, the locking part 401 locks the limiting member 5 in the annular groove 201. When the unlocking control member 4 is rotated so that the clearance part 402 reaches the limiting member 5, a gap is formed between the clearance part 402 and the limiting member 5 that can accommodate the limiting member 5.

[0038] In this embodiment, the quick-release bicycle pedal structure works by rotating the unlocking control 4 to bring the locking part 401 to the limiting part 5. The locking part 401 locks the limiting part 5 in the annular groove 201 of the pedal 2, thus locking the pedal 2 and the crank 1. After rotating the unlocking control 4 to bring the clearance part 402 to the limiting part 5, a gap is formed between the clearance part 402 and the limiting part 5 to accommodate the limiting part 5. Then, the pedal 2 can be pulled out from the pedal sleeve 3 to release the lock between the pedal 2 and the crank 1, thus achieving quick release of the pedal 2.

[0039] Preferably, see Figure 7 The groove of the annular groove 201 has a sloping arc shape. The limiting part 5 is a rolling body. The mounting hole 404 of the unlocking control part 4 is provided with a clearance space 405. The clearance space 405 gradually expands around the rotation direction of the unlocking control part 4. The bottom end of the clearance space 405 is the locking part 401 and the top end is the clearance part 402.

[0040] When it is necessary to unlock pedal 2 from crank 1, manually turn unlock control 4 to deflect it so that the top of clearance space 405 (i.e. clearance part) reaches limit member 5. Then manually pull pedal 2. Because the groove of annular groove 201 has a sloping arc shape, when pedal 2 is pulled outward, the limit member 5 in annular groove 201 will gradually move out and enter clearance space 405, thereby realizing quick release of pedal 2.

[0041] Preferably, in this embodiment, the limiting member 5 is a sphere, specifically a steel ball.

[0042] Preferably, see Figure 1 , Figure 2 and Figure 4 One end of the pedal sleeve 3 extends radially outward to form a first baffle 301, and the other end of the pedal sleeve 3 passes through the through hole 101 on the crank 1 and is engaged with a second baffle 6. The unlocking control 4 is axially limited between the crank 1 and the second baffle 6. In other words, the first baffle 301 and the second baffle 6 together axially limit the pedal sleeve 3 and the unlocking control 4 on the crank 1.

[0043] Preferably, see Figure 4 , Figure 5 , Figure 6 and Figure 8 The end of the foot pedal sleeve 3 is radially recessed to form an annular locking groove 302. One axial end of the annular locking groove 302 is provided with multiple notches 303. Multiple locking blocks 602 extend radially from the wall of the sleeve hole 601 on the second baffle 6. The second baffle 6 is sleeved on the foot pedal sleeve 3 through the locking blocks 602 and passes over the notches 303. After rotating the second baffle 6 to make the locking blocks 602 engage with the annular locking groove 302, the second baffle 6 is engaged with the foot pedal sleeve 3.

[0044] Specifically, see Figure 6 and Figure 8 In this embodiment, three notches 303 are provided, and three corresponding card blocks 602 are also provided.

[0045] Preferably, see Figure 4 The second baffle 6 is detachably connected to the unlocking control 4, and the second baffle 6 completely covers the side of the unlocking control 4 away from the crank 1 to prevent contaminants from entering the unlocking control 4 and ensure the long-term normal use of the unlocking control 4.

[0046] Specifically, see Figure 4 In this embodiment, the second baffle 6 is fastened to the side of the unlocking control 4 away from the crank 1 by three screws.

[0047] Preferably, see Figure 7 The unlocking control 4 is ring-shaped to facilitate manual twisting.

[0048] Preferably, in this embodiment, the outer peripheral surface of the unlocking control 4 is provided with anti-slip knurling, thereby further improving the convenience of manually turning the unlocking control 4.

[0049] Preferably, see Figure 5 and Figure 7 The unlocking control component 4 has multiple weight reduction holes 403 spaced out in a circumferential direction, and each weight reduction hole 403 is hollowed out along the axial direction.

[0050] Specifically, see Figure 7 In this embodiment, the unlocking control component 4 has three weight-reducing holes 403.

[0051] Preferably, see Figure 3 , Figure 5 and Figure 7 The unlocking control 4 is connected to the foot pedal sleeve 3 via a torsion spring 7. When the torsion spring 7 is in its natural state, the unlocking control 4 controls the limiting component 5 to lock the foot pedal 2.

[0052] Specifically, see Figure 3 , Figure 5 and Figure 7 In this embodiment, when the torsion spring 7 is in its natural state, the locking part 401 of the unlocking control 4 locks the limiting member 5 in the annular groove 201. Thus, the torsion spring 7 keeps the locking part 401 on the unlocking control 4 in the state of locking the limiting member 5 in the annular groove 201, ensuring the locking effect between the pedal 2 and the crank 1, making riding safer.

[0053] Preferably, see Figure 7 The unlocking control component 4 has an axially penetrating clearance hole 406 inside its mounting hole 404. The shape of the clearance hole 406 is adapted to the top shape of the limiting component 5. When the unlocking control component 4 is assembled onto the foot pedal cover 3, the clearance hole 406 can be adjusted to face the limiting component 5, thereby avoiding the limiting component 5 and facilitating assembly.

[0054] Better yet, see Figures 5 to 7 In this embodiment, the foot pedal sleeve 3 is provided with a plurality of radially penetrating receiving holes 304 at equal intervals around its outer periphery. Each receiving hole 304 contains a limiting member 5. The mounting hole 404 of the unlocking control member 4 is provided with a plurality of clearance spaces 405 at equal intervals around its outer periphery. The clearance spaces 405 correspond one-to-one with the limiting members 5.

[0055] Better yet, see Figure 7 In this embodiment, the assembly hole 404 of the unlocking control component 4 is provided with a plurality of clearance holes 406 at equal intervals in the circumferential direction, and the clearance holes 406 correspond one-to-one with the receiving holes 304.

[0056] Specifically, in this embodiment, the foot pedal sleeve 3 has three receiving holes 304 and the unlocking control 4 has three clearance holes 406.

[0057] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
