[0036] Example

[0037] The present embodiment is intended to promote the solution to the problem of a stable folding foot pedal with patent application number CN209984855U in the prior art, in which the foot pedal device is a folding part, while the bracket device is not folded and includes the length of the rotating shaft part, resulting in a relatively large length of the entire foot pedal after folding. When the entire pedal is not disassembled, the occupied cross-section is large, and a large space is occupied when the entire vehicle is packaged and transported.

[0038] In this embodiment, the rotating shaft assembly 2 can be folded together with the pedal part. When the whole is not disassembled, the occupied cross section is small, the occupied space is small, and the packaging materials and transportation space are saved. In particular, the middle part of the pedal member 3 of this embodiment is inserted into the rotating shaft assembly 2, and the pedal member 3 can rotate around the entire rotating shaft assembly 2. The stress borne by the pedal member 3, the shaft sleeve 23 and the rotating shaft 21 is evenly distributed, and the pedal member 3 and the shaft sleeve 23 are evenly stressed, and the service life is longer; at the same time, the buckle assembly 4 can also be set in the rotating shaft assembly 2, and the hidden installation is more beautiful as a whole.

[0039] To achieve the above purpose, refer to Figure 1 , 3 and 4, the present embodiment provides a foldable pedal, which is applied to the crank 5 of the bicycle, comprising: a connecting member 1 for detachably connecting with the crank 5, the connecting member 1 being provided with a buckle slot 11; a rotating shaft assembly 2, one end of which is rotatably connected with the connecting member 1; a pedal member 3, the middle part of which is inserted into the rotating shaft assembly 2 and is rotatably connected with the rotating shaft assembly 2; a buckle assembly 4, a buckle assembly 4 is arranged in the rotating shaft assembly 2, the buckle end 4a of the buckle assembly 4 is adapted to the buckle slot 11, and the buckle end 4a of the buckle assembly 4 is buckled into the buckle slot 11, so that the rotating shaft assembly 2 and the crank 5 maintain a vertical state; the buckle end 4a of the buckle assembly 4 is separated from the buckle slot 11, and the rotating shaft assembly 2 can be rotated and folded around the connecting member 1.

[0040] It should be noted that, refer to Figure 1 As shown, in this embodiment, one end of the connecting member 1 is provided with an external thread, and the connecting member 1 is threadedly connected to the crank 5 via the external thread.

[0041] Specifically, refer to Figure 1 and 2As shown, the rotating shaft assembly 2 includes a rotating shaft 21 for inserting the pedal member 3, the interior of the rotating shaft 21 is provided with a receiving cavity for arranging the buckle assembly 4, and the exterior is provided with an opening 211 communicating with the receiving cavity, and the buckle assembly 4 can penetrate into the receiving cavity through the opening 211; the rotating shaft 21 is provided with a shoulder 212 at one end close to the connecting member 1, and a limiting member 22 is provided at the other end, and the pedal member 3 is limited between the limiting member 22 and the shoulder 212; the limiting member 22 is provided with a through hole for the buckle assembly 4 to pass through;

[0042] The snap assembly 4 includes a snap shaft 41 and an elastic member 42. The snap shaft 41 is provided with a snap shoulder 411 at one end close to the connecting member 1. The two ends of the elastic member 42 are respectively abutted against the snap shoulder 411 and the limiting member 22. The elastic deformation of the elastic member 42 is reset so that the end of the snap shaft 41 close to the connecting member 1 can pass through the opening 211 of the accommodating cavity and be snapped into the snap groove 11, and the other end extends out of the through hole of the limiting member 22.

[0043] Specifically, refer to Figure 1 and 2 As shown, the middle part of the pedal member 3 is provided with a through groove 31 for the rotating shaft 21 to penetrate, and the two ends of the through groove 31 are respectively provided with stepped grooves 32; the rotating shaft assembly 2 also includes a sleeve 23, and the stepped groove 32 is respectively provided with a sleeve 23; the shoulder 212 and the limiter 22 of the clamping shaft 41 are respectively in contact with the two sleeves 23, and the outer ring diameter of the sleeve 23 is larger than the shoulder 212 and the limiter 22. It should be noted that the shoulder 212 adopts a smooth surface with a low friction coefficient. In some embodiments, the sleeve 23 can also be replaced by a bearing. The purpose of the outer ring diameter of the sleeve 23 being larger than the shoulder 212 and the limiter 22 is to prevent the shoulder 212 from contacting the inner wall of the through groove 31, which has a high friction coefficient, and secondly, to prevent the limiter 22 from rotating when the pedal member 3 rotates, causing the limiter 22 to loosen or even fall off.

[0044] Specifically, refer to Figure 1 and 2 As shown, both sides of the end of the rotating shaft 21 are provided with protrusions 213 extending along the axis of the rotating shaft 21, and the connecting member 1 is inserted between the two protrusions 213, and the shaft pin 214 passes through the protrusions 213 and the connecting member 1 in sequence, and the rotating shaft assembly 2 and the crank 5 are in a vertical state, and the snap groove 11 is aligned with the opening 211 of the accommodating cavity.

[0047] In order to improve driving safety, refer to Figure 1 and 2 As shown, in this embodiment, reflectors 34 are provided on both sides of the pedal member 3, and anti-skid protrusions 35 are provided on the end surface of the pedal. The reflectors 34 are conspicuous when driving at night, and are easy to be noticed by oncoming vehicles; the anti-skid protrusions 35 increase the friction between the footboard and the surface of the pedal member 3.

[0048] Reference Figure 1 and 4 As shown, the buckle slot 11 is a circular slot, and the buckle end 4a of the clamping shaft 41 can be clamped into the slot to form an all-round wrapping state. When stepping on the pedal 3, the position limit of the azimuth wrapping state is stable, and the clamping shaft 41 is not easy to separate from the buckle slot 11, thereby improving the safety factor of the pedal.

[0049] Reference Figure 1 and 2 As shown, the size of the buckle end 4a of the clamping shaft 41 is narrowed at the front end. The purpose is that the buckle end 4a of the clamping shaft 41 can be effectively clamped in the buckle notch 11 under the action of the elastic member 42 and is not easy to loosen.

[0050] This embodiment also provides a bicycle, including a crank 5 and the above-mentioned folding pedal, which is detachably connected to the end of the crank 5; when the folding pedal is in an unlocked state, the pedal member 3 can be rotated around the connecting member 1 and folded to the crank 5, and in a locked state, the pedal member 3 is perpendicular to the crank 5.

[0051] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
