Description

Technical Field

[0001] The present application belongs to the technical field of bicycles, and more specifically, relates to a pedal device and a bicycle. Background Art

[0002] In the related art, some racing bicycles, road bicycles, and other bicycles do not require parking racks to reduce unnecessary accessories on the bicycle, improve the overall balance of the bicycle, and thus improve the bicycle's riding speed and balance when negotiating corners. However, when not being ridden, these bicycles often need to be leaned against a wall or supported by the user to achieve stable parking to prevent the bicycle from falling and being damaged. Based on this, when not being ridden, the bicycle needs to find an appropriate place to park or requires the user to continuously support it, which makes the bicycle less convenient to park.

[0043] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0044] See also Figure 1 The present application provides a pedal device for installation on a bicycle. For example, when the pedal device is used on a bicycle, the user can step on the pedal device to propel the bicycle forward, and the pedal device can also be used to support the bicycle on the ground when parking is required, ensuring stable parking. Furthermore, the pedal device can also be used on other types of vehicles, such as electric vehicles and unicycles. The following description will use a bicycle as an example of the application of the pedal device.

[0045] Please also refer to Figures 1 to 4 The pedal device provided in the embodiment of the present application includes a pedal structure 10, a limiting structure 20 and a support assembly 30. The pedal structure 10 includes a pedal 11 and a connecting shaft 12. The connecting shaft 12 is rotatably connected to the pedal 11. The limiting structure 20 is provided on the pedal 11 and can reciprocate on the pedal 11. The limiting structure 20 can move to be engaged with the connecting shaft 12 to limit the relative rotation between the connecting shaft 12 and the pedal 11. The support assembly 30 includes a support member 31, which is rotatably connected to the pedal 11 and can be rotated to a folded state or an unfolded state relative to the pedal 11. In the folded state, the support member 31 is folded on the pedal 11. In the unfolded state, the support member 31 is unfolded from the pedal 11, the support member 31 is used for support, and the support member 31 abuts against the limiting structure 20 so that the limiting structure 20 is engaged with the connecting shaft 12.

[0046] The pedal 11 is generally configured as a thin plate and has four surfaces around the outer circumference of the connecting shaft 12. Two opposing surfaces are configured to be wider to facilitate user pedaling, while the remaining two surfaces are configured to be narrower. During use, the user can attach the support assembly 30 to at least one of the four surfaces.

[0047] It should be noted that the support member 31 is folded on the pedal 11, and can be set so that the support member 31 is attached to the surface of the pedal 11 to achieve the folding effect of the support member 31; or, the support member 31 is folded on the pedal 11, and can also be set so that at least part of the support member 31 enters the interior of the pedal 11 to reduce the space occupied by the support member 31 and achieve the folding effect of the support member 31.

[0048] The support member 31 can be made of aluminum alloy, stainless steel or other materials that have a certain bearing capacity and good wear resistance and rust resistance.

[0049] In one implementation, the limiting structure 20 may have a groove on the side facing the connecting shaft 12, with a protrusion on the connecting shaft 12 engaging with the groove. Alternatively, the limiting structure 20 may have a protrusion on the side facing the connecting shaft 12, with a groove on the connecting shaft 12 engaging with the protrusion. In actual use, the concave-convex engagement between the limiting structure 20 and the connecting shaft 12 achieves a rotational limit effect on the connecting shaft 12 about its own rotation axis.

[0050] The pedal device provided in the embodiment of the present application allows the user to rotate the support member 31 relative to the pedal 11 when not riding the bicycle, so that the support member 31 rotates to an expanded state in which it is expanded from the pedal 11. In the expanded state, the support member 31 abuts against the limiting structure 20, so that the limiting structure 20 is engaged with the connecting shaft 12, limiting the relative rotation of the connecting shaft 12 and the pedal 11, so that the pedal 11 does not drive the support member 31 to rotate relative to the connecting shaft 12. At this time, the support member 31 can be supported on the ground or other surface, so that the bicycle can be parked stably. In this way, when the bicycle is not being ridden, the user does not need to find a suitable place to park the bicycle, nor does the user need to continuously hold the bicycle by hand. The bicycle can be stably parked by simply rotating the support member 31 to put it in the expanded state and supporting the support member 31 on the ground or other surface, thereby improving the parking convenience of the bicycle.

[0051] It can be understood that when the support member 31 rotates to a folded state relative to the pedal 11, the support member 31 no longer presses against the limiting structure 20, and the limiting structure 20 can be disengaged from the connecting shaft 12, that is, the limiting structure 20 is no longer clamped on the connecting shaft 12. At this time, the pedal 11 can rotate relative to the connecting shaft 12.

[0052] In some embodiments, the pedal 11 can be configured to have multiple anti-slip parts 60 on the outer surface. For example, raised pins can be provided on the outer surface of the pedal 11, or raised stripes, patterns, etc. can be provided on the outer surface of the pedal 11 to improve the problem of users easily slipping when stepping on the pedal 11, thereby improving the anti-slip performance of the pedal structure 10 and the friction with the sole of the user's shoe, making riding more labor-saving and reliable.

[0053] In some embodiments, see Figures 2 to 4 The pedal 11 is provided with a receiving groove 111. In the folded state, at least a portion of the support member 31 is received in the receiving groove 111.

[0054] In one embodiment, in the folded state, all of the support assembly 30 is accommodated in the accommodation groove 111. Alternatively, in another embodiment, in the folded state, a portion of the support assembly 30 is accommodated in the accommodation groove 111, while another portion is exposed outside the accommodation groove 111.

[0055] In this way, at least a portion of the support assembly 30 can be accommodated within the receiving groove 111 in the folded state, reducing the risk of wear and tear caused by friction between the support assembly 30 and the user's shoe sole during riding, thereby extending the service life of the support assembly 30. Furthermore, the support assembly 30 being accommodated within the receiving groove 111 allows at least a portion of the support assembly 30 to be installed within the pedal 11. The support assembly 30 occupies less space in the folded state, improving the neatness of the pedal assembly, reducing the overall size of the pedal assembly, and improving the balance performance of the bicycle.

[0056] In some embodiments, see Figures 1 to 5 The support member 31 is provided with a first slot 311 and a second slot 312. The first slot 311 and the second slot 312 are spaced apart and surround the outer peripheral wall of the rotation axis of the support member 31. The pedal device also includes a clamping structure 40. The clamping structure 40 is movably connected to the pedal 11. In the folded state, the clamping structure 40 is clamped in the first slot 311 to limit the relative rotation of the support member 31 and the pedal 11. In the unfolded state, the clamping structure 40 is clamped in the second slot 312 to limit the relative rotation of the support member 31 and the pedal 11.

[0057] The rotation axis of the support member 31 is defined as the first axis L1 .

[0058] In the circumferential direction around the first axis L1, the groove walls on opposite sides of the first engaging groove 311 can abut the engaging structure 40. In the circumferential direction around the first axis L1, the groove walls on opposite sides of the second engaging groove 312 can also abut the engaging structure 40. Thus, when the engaging structure 40 is engaged with the first engaging groove 311 or the second engaging groove 312, the support member 31 rotates, causing the groove walls of the first engaging groove 311 or the second engaging groove 312 to abut against the engaging structure 40. The engaging structure 40 is then constrained to be positioned on the pedal 11 in the direction around the first axis L1, preventing the support member 31 from rotating relative to the pedal 11.

[0059] When parking, the user first adjusts the support member 31 relative to the pedal 11 so that the support member 31 can rotate to abut against the limiting structure 20 and support the support member 31 on the ground. Then, the user can drive the clamping member 41 to approach and clamp it into the second clamping slot 312. The support assembly 30 can be stably fixed in the above-mentioned unfolded state due to the limitation of the slot wall of the second clamping slot 312. When it is necessary to fold the support member 31, the user drives the clamping member 41 out of the second clamping slot 312, and then adjusts the support member 31 relative to the pedal 11 to rotate to the folded state. Then, the user adjusts the clamping member 41 to pass through the first clamping slot 311 to achieve the fixation of the clamping member 41 in the folded state.

[0060] In this way, when the support member 31 is rotated to the folded state or the unfolded state, it can remain in the above state and is not easy to rotate and deviate from the above state under external force or bumps. This is beneficial for the support member 31 to remain in the folded state without falling out during the user's riding process, thereby improving the safety of the pedal device. It is also beneficial for the stable support of the support member 31 when the bicycle is parked, thereby improving the support stability of the support member 31.

[0061] It is understood that the support member 31 may include a rotating connection portion 316 and a support portion 315 connected to the rotating connection portion 316. The rotating connection portion 316 is rotatably connected to the pedal 11, and the support portion 315 is used to provide support. For example, the support portion 315 may be, but is not limited to, configured in a rod shape to facilitate support on the ground.

[0062] In some embodiments, the first card slot 311 and the second card slot 312 can be provided on the rotating connection portion 316 ; or, in some other embodiments, the first card slot 311 and the second card slot 312 can also be provided on the support portion 315 .

[0063] It should be noted that the clamping member 41 is inserted into the first clamping slot 311 or the second clamping slot 312 to achieve the clamping connection. The insertion direction of the clamping member 41 can be a direction perpendicular to the first axis L1, or can be other directions that are not perpendicular to the first axis L1. For example, the insertion direction of the clamping member 41 can be a direction parallel to the first axis L1.

[0064] When the insertion direction of the clamping member 41 is perpendicular to the first axis L1 , the first clamping slot 311 and the second clamping slot 312 may be provided on the outer peripheral wall of the rotation connection portion 316 surrounding the first axis L1 .

[0065] When the plug-in direction of the connector 41 is not perpendicular to the first axis L1, the first slot 311 and the second slot 312 can be arranged on the outer peripheral wall of the rotating connection part 316 surrounding the first axis L1, or they can not penetrate the above-mentioned outer peripheral wall, but be arranged on other wall surfaces of the rotating connection part 316 except the outer wall surface surrounding the first axis L1.

[0066] In some embodiments, at least a portion of the outer peripheral wall of the rotating connection portion 316 around the first axis L1 can be set as an arc surface, so that the distance between at least a portion of the outer peripheral wall of the rotating connection portion 316 around the first axis L1 and the pedal 11 remains consistent during rotation, reducing the risk of wear between the outer peripheral wall of the rotating connection portion 316 around the first axis L1 and the pedal 11 during rotation.

[0067] In some embodiments, see Figures 2 to 5 The pedal 11 is provided with a guide hole 112. The engaging structure 40 includes a engaging member 41. The engaging member 41 is reciprocally disposed within the guide hole 112. The first engaging slot 311 and the second engaging slot 312 can be alternately rotated to face the guide hole 112, so that the engaging member 41 can alternately engage with the first engaging slot 311 or the second engaging slot 312.

[0068] The clip 41 passing through the guide hole 112 can be configured to be partially passed through the guide hole 112 and partially extended outside the guide hole 112. The portion of the clip 41 passing through the guide hole 112 can move to alternately engage with the first slot 311 or the second slot 312, while the portion of the clip 41 outside the guide hole 112 is provided for manual adjustment by the user.

[0069] It is understood that when the first slot 311 and the guide hole 112 are aligned, the engaging member 41 can pass through the guide hole 112 and enter the first slot 311 to achieve engagement with the first slot 311. When the second slot 312 and the guide hole 112 are aligned, the engaging member 41 can pass through the guide hole 112 and enter the second slot 312 to achieve engagement with the second slot 312.

[0070] During use, the user can rotate the support member 31 about the first axis L1 until the support member 31 enters the folded state, at which point the first engaging slot 311 rotates to correspond to the guide hole 112. The user then adjusts the engaging member 41 so that it passes along the guide hole 112 and engages with the first engaging slot 311. This prevents the support member 31 from further rotating relative to the pedal 11, thereby limiting the position of the support member 31 in the folded state. The user can also adjust the engaging member 41 so that it passes out of the first engaging slot 311, thereby rotating the support member 31 about the first axis L1, until the support member 31 enters the deployed state, at which point the second engaging slot 312 rotates to correspond to the guide hole 112. The user then adjusts the engaging member 41 so that it passes along the guide groove 114 and enters the second engaging slot 312. This prevents the support member 31 from further rotating relative to the pedal 11, thereby limiting the position of the support member 31 in the deployed state.

[0071] In this way, the support member 31 can be limited around the first axis L1 in both the folded state and the unfolded state, so that the support member 31 is not easy to fall off from the pedal 11 in the folded state, and the support member 31 is not easy to rotate when supported on the ground to cause unstable support, thereby improving the stability and safety of the pedal device.

[0072] The extension direction of the guide hole 112, that is, the relative direction between the first engaging slot 311 and the guide hole 112, can be a direction perpendicular to the first axis L1, or can be another direction not perpendicular to the first axis L1. The relative direction between the first engaging slot 311 and the guide hole 112 is also the engaging direction of the engaging member 41, that is, the engaging direction of the engaging member 41 is also the extending direction of the guide hole 112, so that the engaging member 41 can engage with the first engaging slot 311 when moving in the guide hole 112.

[0073] In some embodiments, as Figure 3 As shown, the extending direction of the guide hole 112 in this embodiment is perpendicular to the first axis L1.

[0074] Furthermore, the extending direction of the guide hole 112 may be substantially parallel to the reciprocating motion direction of the limiting structure 20 .

[0075] In other embodiments, the extending direction of the guide hole 112 may not be perpendicular to the first axis L1 . For example, the extending direction of the guide hole 112 may be parallel to the first axis L1 .

[0076] In some embodiments, please refer to FIG. Figure 5 The clamping structure 40 further includes a first elastic structure 42 . Along the movement direction of the clamping member 41 , the first elastic structure 42 abuts between the pedal 11 and the clamping member 41 .

[0077] The first elastic structure 42 can be, but is not limited to, a spring, a spring, etc.

[0078] When a user applies force to drive the clamping member 41 toward the support member 31, the first elastic structure 42 compresses and accumulates elastic potential energy. When the user releases the clamping member 41, the first elastic structure 42 releases the elastic potential energy and, through elastic force, drives the clamping member 41 away from the support member 31, causing the clamping member 41 to disengage from the first engaging slot 311 or the second engaging slot 312 on the support member 31. The provision of the first elastic structure 42 simplifies the driving method of the clamping member 41 and improves the driving efficiency of the clamping member 41.

[0079] In one possible design, the pedal 11 is provided with a limiting groove 113. The clamping member 41 is provided with a limiting portion 411, which is disposed within the limiting groove 113. Along the movement direction of the clamping member 41, the first elastic structure 42 abuts between the pedal 11 and the limiting portion 411. When the clamping member 41 moves, the limiting portion 411 is retained within the limiting groove 113 along the direction of movement of the clamping member 41.

[0080] The limiting portion 411 may be a protruding structure provided on the clamping member 41 , or, in some other embodiments, the limiting portion 411 may be a pin, a bolt, etc. detachably connected to the clamping member 41 .

[0081] It can be understood that the limiting groove 113 is configured so that when the limiting portion 411 follows the movement of the clamping member 41 and moves to the side groove wall of the limiting groove 113 away from the support member 31, the clamping member 41 disengages from the support member 31; when the limiting portion 411 follows the movement of the clamping member 41 and moves to the side groove wall of the limiting groove 113 close to the support member 31, the clamping member 41 can be clamped in the first clamping slot 311 or the second clamping slot 312.

[0082] In this way, the user can lock or release the support member 31 by adjusting the movement of the clamping member 41, and the movement stroke of the clamping member 41 along the movement direction is limited, so that the clamping member 41 is not easy to disengage from the guide hole 112 during adjustment, and it is not easy to damage the support member 31 due to excessive adjustment.

[0083] In one embodiment, see Figure 5 The number of the second slot 312 is one. The snap-fit structure 40 can be snap-fitted to the second slot 312 in the unfolded state.

[0084] Alternatively, in some other embodiments, there are multiple second slots 312 , which are spaced apart and surround the outer circumference of the first axis L1 , and the engaging structure 40 is used to alternately engage with the multiple second slots 312 .

[0085] The number and distribution of the second slots 312 can be selected according to the actual needs of the user. It is understandable that the more second slots 312 are set and the smaller the distance between two adjacent second slots 312 is, the more adjustment levels of the support member 31 can be adjusted.

[0086] In this way, the user can rotate the support member 31 around the first axis L1 to multiple angles when the support member 31 is in the unfolded state, and the support member 31 can be fixed at the above-mentioned multiple angles by the second card slot 312 and the card connection structure 40, so that the support member 31 can be supported on the ground in the unfolded state at a variety of usage angles, thereby improving the flexibility and convenience of use of the support member 31.

[0087] In some embodiments, see Figure 3 In the first direction X, the portion of the limiting structure 20 used to abut the support member 31 is spaced apart from the rotation axis of the support member 31 . The first direction X is perpendicular to the movement direction of the limiting structure 20 .

[0088] It can be understood that the portion of the limiting structure 20 used for abutting and the first axis L1 are spaced apart along the first direction X. It can be concluded that the first direction X and the first axis L1 are not parallel.

[0089] The portion of the limiting structure 20 used to abut the support member 31 is spaced apart from the first axis L1 so that the component of the force when the limiting structure 20 abuts the support member 31 can provide pressure to the support member 31 along the first direction X, thereby inhibiting the rotation of the support member 31.

[0090] The first direction is as follows Figure 3 The direction X shown in FIG. 1 is the direction of movement of the limiting structure 20. Figure 3 The direction Z is shown in the figure. Figure 3 Direction Y is also indicated in the figure. Direction X, direction Y and direction Z are the directions of the three coordinate axes in the spatial coordinate system, that is, direction X is perpendicular to direction Y, direction X is perpendicular to direction Z, and direction Y is perpendicular to direction Z.

[0091] Thus, as the support member 31 rotates, a portion of the support member 31 gradually approaches the limiting structure 20 along the first direction X, and can abut against the limiting structure 20 during rotation, causing the limiting structure 20 to engage with the connecting shaft 12. Simultaneously, the support member 31 is restrained by the limiting structure 20 and is unable to continue rotating. Thus, the limiting structure 20 limits the rotational range of the support member 31 when deployed, making it less likely that the bicycle will fall or become unstable due to an excessively large deployment angle, thereby ensuring that the support member 31 remains stably and reliably supported on the ground.

[0092] In some embodiments, see Figure 6and Figure 7 The connecting shaft 12 includes a shaft body 121 and a stopper 122. The shaft body 121 is rotatably connected to the pedal 11. The stopper 122 is provided on the shaft body 121. The stopper 122 has a plurality of fourth slots 1221 formed on an outer peripheral wall surrounding the rotation axis of the shaft body 121. The stopper structure 20 can be alternately engaged with the plurality of fourth slots 1221.

[0093] The rotation axis of the shaft body 121 , ie, the rotation axis of the connecting shaft 12 , is defined as the second axis L2 .

[0094] The limiting member 122 may be a screw structure having a plurality of teeth connected to the shaft body 121 , or the limiting member 122 may be a gear sleeved and fixed on the shaft body 121 .

[0095] It can be understood that when the limiting structure 20 is engaged in the fourth slot 1221, the groove walls on both sides of the fourth slot 1221 can be supported against the limiting structure 20 around the second axis L2. Since the limiting structure 20 is limited on the pedal 11 around the second axis L2, the limiting structure 20 can limit the rotation of the limiting member 122 around the second axis L2, thereby limiting the rotation of the shaft 121.

[0096] In this way, when the support assembly 30 is in the expanded state, the limiting structure 20 limits the rotation of the limiting member 122, thereby making it difficult for the shaft 121 to rotate, thereby reducing the risk of the shaft 121 rotating and causing the support member 31 to shake, and improving the support stability of the support member 31 on the ground, making it difficult for the bicycle to fall over when parked.

[0097] In some embodiments, see Figure 6 The pedal 11 is provided with a guide groove 114 . At least a portion of the limiting structure 20 is provided in the guide groove 114 and is configured to reciprocate along the guide groove 114 .

[0098] As an example, the limiting structure 20 can move in the guide groove 114 along the second direction Z, and the second direction Z intersects with the second axis L2.

[0099] The second axis L2 intersects the second direction Z, which means that the second axis L2 and the second direction Z may form an angle greater than 0° and less than 180°, that is, the second axis L2 and the second direction Z are not parallel. The second axis L2 and the second direction Z may be perpendicular to each other, or they may not be perpendicular to each other. The second axis L2 and the second direction Z may be directions intersecting on the same plane, or they may be directions on different planes, and the projection of the second direction Z on the plane where the second axis L2 lies may intersect with the second axis L2. As an example, the second axis L2 may be perpendicular to the second direction Z.

[0100] When the limiting structure 20 moves along the second direction Z, the limiting structure 20 is located at the groove wall of the guide groove 114 in a direction intersecting the second direction Z. In this way, the limiting structure 20 can move along the second direction Z during movement, so that the limiting structure 20 can be accurately aligned with the connecting shaft 12, which is conducive to the engagement between the limiting structure 20 and the connecting shaft 12.

[0101] Through the above scheme, the limiting structure 20 is arranged in the guide groove 114, and the guide groove 114 guides the movement trajectory of the limiting structure 20, so that the limiting structure 20 can move along the guide groove 114, thereby improving the alignment accuracy between the limiting structure 20 and the connecting shaft 12, and is also beneficial to the stable installation of the limiting structure 20 on the pedal 11.

[0102] In some embodiments, see Figure 6 The pedal device further includes a second elastic structure 50. The second elastic structure 50 abuts against the limiting structure 20. The second elastic structure 50 is used to provide an elastic force for the limiting structure 20 to move away from the connecting shaft 12.

[0103] The second elastic structure 50 can be a structure such as a spring, a spring, or a rubber member, and is used to accumulate elastic potential energy when the support member 31 presses against the limiting structure 20, and release the elastic potential energy when the support member 31 releases the limiting structure 20, so as to push the limiting structure 20 away from the connecting shaft 12 through elastic force.

[0104] The provision of the second elastic structure 50 allows for a simple and reliable push-off effect against the limiting structure 20. The second elastic structure 50 is simple and easy to manufacture, and does not require manual adjustment by the user, thus reducing the number of steps required to operate the pedal device. Furthermore, along the direction of movement of the limiting structure 20, the second elastic structure 50 provides a certain degree of cushioning against the relative motion between the pedal 11 and the limiting structure 20.

[0105] In one possible design, a portion of the pedal 11 structure is spaced apart from the limiting structure 20, and the second elastic structure 50 is disposed between the portion of the pedal 11 structure and the limiting structure 20. The connecting shaft 12 is disposed on the side of the portion of the pedal 11 structure away from the limiting structure 20. The second elastic structure 50 can drive the limiting structure 20 away from the portion of the pedal 11 structure through the elastic force generated by elastic deformation.

[0106] In some embodiments, see Figure 6 The limiting structure 20 includes a first transmission member 21 and a second transmission member 22. The first transmission member 21 and the second transmission member 22 are arranged along the movement direction of the limiting structure 20. The first transmission member 21 and the second transmission member 22 are both arranged on the pedal 11 for reciprocating movement. The support member 31 is used to support the first transmission member 21. The first transmission member 21 is used to push the second transmission member 22. The second transmission member 22 is used to be clamped to the connecting shaft 12.

[0107] The first transmission member 21 and the second transmission member 22 can be columnar structures, sheet structures, etc.

[0108] In a possible design, the second transmission member 22 is provided with a protruding tip, so that the protruding portion of the second transmission member 22 is more easily engaged with the connecting shaft 12 .

[0109] In some embodiments, the second elastic structure 50 includes a first elastic member. Along the movement direction of the limiting structure 20 , the first elastic member abuts between the first transmission member 21 and the pedal 11 .

[0110] It can be understood that the first elastic member is disposed on a side of the first transmission member 21 close to the second transmission member 22 .

[0111] When parking, the user drives the support member 31 to rotate, causing the support member 31 to press against the first transmission member 21. The first transmission member 21 moves toward the second transmission member 22, and the first transmission member 21 pushes the second transmission member 22 to move. The first elastic member between the first transmission member 21 and the pedal 11 is compressed and stores energy. When the second transmission member 22 is engaged with the connecting shaft 12, the connecting shaft 12 is not easy to rotate, and the support member 31 can be stably supported on the ground. When releasing the parking state, the user drives the support member 31 away from the first transmission member 21. The first elastic member releases its elastic potential energy, driving the first transmission member 21 to move away from the second transmission member 22. At this time, the second transmission member 22 is disengaged from the connecting shaft 12, and the pedal 11 can rotate relative to the connecting shaft 12.

[0112] In this way, the first elastic member provides a buffering effect between the first transmission member 21 and the pedal 11, and can drive the first transmission member 21 away from the second transmission member 22 during the process of the support member 31 rotating to the folded state, so that the second transmission member 22 disengages from the limiting groove 113 and restores the rotation of the pedal 11.

[0113] In some embodiments, see Figure 6 The second elastic structure 50 includes a second elastic member 51 . Along the movement direction of the limiting structure 20 , the second elastic member 51 abuts between the second transmission member 22 and the pedal 11 .

[0114] When parking, the user drives the support member 31 to rotate, causing the support member 31 to press against the first transmission member 21. The first transmission member 21 moves toward the second transmission member 22, and the first transmission member 21 pushes the second transmission member 22 to move. The second elastic member 51 between the first transmission member 21 and the second transmission member 22 is compressed and stores energy. When the second transmission member 22 is engaged with the connecting shaft 12, the connecting shaft 12 is not easy to rotate, and the support member 31 can be stably supported on the ground. When releasing the parking state, the user drives the support member 31 away from the first transmission member 21, the second elastic member 51 releases the elastic potential energy, and pushes the first transmission member 21 away from the second transmission member 22. At this time, the first transmission member 21 is away from the connecting shaft 12, and the second transmission member 22 is also away from the connecting shaft 12, so that the pedal 11 can rotate relative to the connecting shaft 12.

[0115] In this way, the first elastic member provides a buffering effect for the movement between the first transmission member 21 and the second transmission member 22, and can drive the first transmission member 21 away from the second transmission member 22 during the process of the support member 31 rotating to the folded state, so that the second transmission member 22 disengages from the limiting groove 113 and restores the rotation of the pedal 11.

[0116] In some embodiments, see Figure 6 The second elastic structure 50 further includes a third elastic member 52 . Along the movement direction of the limiting structure 20 , the third elastic member 52 abuts between the second transmission member 22 and the first transmission member 21 .

[0117] When parking, the user drives the support member 31 to rotate, causing the support member 31 to press against the first transmission member 21, and the first transmission member 21 moves toward the second transmission member 22. The first transmission member 21 pushes the second transmission member 22 to move, and the third elastic member 52 between the second transmission member 22 and the first transmission member 21 is compressed to store energy. When the second transmission member 22 is engaged with the connecting shaft 12, the connecting shaft 12 is not easy to rotate, and the support member 31 can be stably supported on the ground. When releasing the parking state, the user drives the support member 31 away from the first transmission member 21, and the first transmission member 21 moves away from the second transmission member 22. The third elastic member 52 releases its elastic potential energy, driving the first transmission member 21 to move away from the second transmission member 22, so that the second transmission member 22 can be disengaged from the connecting shaft 12, and the pedal 11 can rotate relative to the connecting shaft 12.

[0118] In this way, the first elastic member provides a buffering effect between the second transmission member 22 and the first transmission member 21, and can drive the first transmission member 21 away from the second transmission member 22 during the process of the support member 31 rotating to the folded state, so that the second transmission member 22 disengages from the connecting shaft 12 and restores the rotation of the pedal 11.

[0119] In some embodiments, see Figure 5 and Figure 6The support member 31 is provided with a first abutting portion 313. The limiting structure 20 is provided with a second abutting portion 23. The first abutting portion 313 is used to abut the second abutting portion 23. The surface of the first abutting portion 313 and the surface of the second abutting portion 23 are both spherical.

[0120] In one possible design, both the support member 31 and the limiting structure 20 are provided with grooves, the first abutting portion 313 is a ball rollably disposed in the groove, and the second abutting portion 23 is also a ball rollably disposed in the groove, so that when the support member 31 rotates, the first abutting portion 313 and the second abutting portion 23 can abut against each other through point contact. Alternatively, in another possible design, the first abutting portion 313 can also be a spherical protrusion protruding toward the second abutting portion 23, and the second abutting portion 23 can also be a spherical protrusion protruding toward the first abutting portion 313, so that when the support member 31 rotates, the first abutting portion 313 and the second abutting portion 23 can abut against each other through point contact.

[0121] In this way, when relative rotation occurs between the support assembly 30 and the limiting structure 20, the friction resistance between the support assembly 30 and the limiting structure 20 is smaller, making the support assembly 30 and the limiting structure 20 less likely to wear, thereby extending the service life of the support member 31 and the limiting structure 20.

[0122] In some embodiments, see Figures 1 to 6 The pedal 11 has a first side 1101, a first surface 1102, a second side 1103, and a second surface 1104, which are sequentially arranged on the outer periphery of the pedal 11 around the second axis L2. The first surface 1102 and the second surface 1104 are disposed opposite each other. Both the first surface 1102 and the second surface 1104 are configured for a user to step on. The first side 1101 and the second side 1103 are disposed opposite each other along the direction of movement of the limiting structure 20. A support member 31 is provided on at least one of the first side 1101 and the second side 1103.

[0123] It is understood that the areas of first surface 1102 and second surface 1104 are larger than those of first side 1101 and second side 1103, so that first surface 1102 and second surface 1104 can be better positioned for a user to step on. Support assembly 30 is disposed on at least one of first side 1101 and second side 1103, making support assembly 30 less susceptible to being stepped on while riding the bicycle, thereby increasing the service life of support assembly 30.

[0124] The support assembly 30 can be provided on the first side 1101 of the pedal 11, or the support assembly 30 can be provided on the second side 1103 of the pedal 11, or the support assembly 30 can be provided on both the first side 1101 and the second side 1103 of the pedal 11. In this way, the user does not need to frequently rotate the pedal 11 during use, and the support assemblies 30 on both the first side 1101 and the second side 1103 of the pedal 11 can be deployed from the pedal 11 to be supported on the ground.

[0125] In this way, the support component 30 is installed on at least one of the first side 1101 and the second side 1103, which improves the convenience of use of the support component 30, and the first side 1101 or the second side 1103 of the support component 30 is not used for users to step on, so it is not easy to cause damage to the support component 30, thereby extending the service life of the support component 30.

[0126] In some embodiments, see Figure 4 The pedal 11 is provided with a first magnetic member 115. The support member 31 is provided with a second magnetic member 314. In the folded state, the first magnetic member 115 is attracted to the second magnetic member 314.

[0127] When the support member 31 is in a folded state, the second magnetic member 314 is magnetically attracted to the first magnetic member 115 on the pedal 11. In the folded state, the connection stability between the support member 31 and the pedal 11 is further enhanced, and the support member 31 is not easy to unfold from the pedal 11 under vibration or collision conditions.

[0128] Specifically, the second magnetic member 314 may be disposed on the support portion 315 of the support member 31 , and the second magnetic member 314 may be disposed on a side of the support portion 315 close to the pedal 11 around the first axis L1 .

[0129] A bicycle according to a second embodiment of the present application includes a frame, a transmission wheel set, and the pedal device of the first embodiment of the present application. The transmission wheel set is arranged on the frame. A connecting shaft 12 of the pedal device is connected to the transmission wheel set.

[0130] The pedal device involved in the embodiment of the present application is the same as the pedal device involved in the above embodiment. For details, please refer to the relevant description above and will not be repeated here.

[0131] The frame is the structure that supports the bicycle's components. All bicycle components can be directly or indirectly mounted on the frame. Frames are typically made from stable materials such as carbon fiber, aluminum alloy, steel, or titanium.

[0132] The transmission wheel set refers to the structure that realizes the travel of the bicycle through the transmission of the transmission parts. The transmission wheel set can include components such as cranks, gear plates, chains, flywheels, transmissions and wheels.

[0133] Specifically, during operation, the user applies force to the pedals 11 by stepping on them, causing them to rotate. The pedals 11 are connected to a gear plate via a crank, which is then connected to the crank and chain. The chain, in turn, is connected to a flywheel, which transmits energy to the wheels. The wheels generate friction with the ground, and their rotation further propels the bicycle forward. The flywheel and the transmission work together to control the chain's movement between gears, achieving speed change.

[0134] When not riding, the bicycle provided in the embodiment of the present application can be supported on the ground by the support member 31 of the pedal device, so that the bicycle is stably parked on the ground via the support member 31. In this way, when not riding the bicycle, the user does not need to find a suitable place to park the bicycle, nor does the user need to continuously hold the bicycle by hand. The user can simply rotate the support member 31 to put it in an unfolded state and support it on the ground, thereby improving the convenience and flexibility of bicycle parking.

[0135] In some embodiments, the pedal device is provided in a plurality of ways. The plurality of pedal devices are arranged on opposite sides of the frame. The connecting shaft 12 of each pedal device is connected to the transmission wheel set.

[0136] For example, a typical bicycle has two pedal devices. A user can simultaneously step on the pedal devices on opposite sides of the frame to propel the bicycle forward. Both pedal devices can be parked using support member 31. Alternatively, some specialized bicycles have three or more pedal devices, allowing multiple users to simultaneously step on the pedal devices on both sides of the frame.

[0137] When not riding, the bicycle provided in the embodiment of the present application can be supported on the ground by the support members 31 of the pedal assembly on either side, allowing the bicycle to be stably parked on the ground via the support members 31. Thus, when not riding, the user does not need to find a suitable place to park the bicycle, nor does the user need to constantly hold the bicycle. Instead, the user can simply rotate the support members 31 on either side to expand the bicycle and support it on the ground, thereby improving the convenience and flexibility of bicycle parking.

[0138] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
