Referring to fig. 6 and 8, in use, the buckle piece 2 is locked on the sole of the shoe B at a position corresponding to the sole a1, the engaging portion 23 of the front end 21 of the buckle piece 2 is inserted into the engaging groove 13 of the front end 11 of the pedal 1, so that the front end 21 of the buckle piece 2 is assembled on the front end 11 of the pedal 1, then the rear edge a2 of the sole a1 of the user applies a downward pressing force P1 to the rear end 22 of the buckle piece 2, and the rear end 22 of the buckle piece 2 is pressed down to contact the rear end 12 of the pedal 1, so that the magnet 51 on the top of the rear end 12 of the pedal 1 attracts the metal bottom plate 61 on the bottom of the rear end 22 of the buckle piece 2, and the rear end 22 of the buckle piece 2 is elastically assembled on the rear end 12 of the pedal 1, and the rear retaining wall 17 is blocked at the outer side of the rear end 22 of the buckle piece 2.

Referring to fig. 6, 8 and 10, when the user performs a circumferential pedaling motion of pedaling the bicycle pedal 1 forward and downward, the thigh and the lower leg are extended forward and downward, and the shoe B naturally brings the rear end 22 of the cleat 2 down relative to the rear edge a2 of the sole a1 to abut against the rear end 12 of the pedal 1, so as to force the metal bottom plate 61 to compress the spring 31 upward, and the rear end 12 of the pedal 1 and the rear end 22 of the cleat 2 are elastically folded.

As shown in the states (E) to (H) of fig. 7, 9 and 10, when the user lifts the bicycle pedal 1 backward and upward to perform a circular pedaling motion, since the thigh and the lower leg are also bent backward F1 and upward F2, the rear edge a2 of the user's foot a1 generates an upward pulling force P2 along with the movement of the lower leg, so that the shoe B is naturally slightly bent upward relative to the rear edge a2 of the user's foot a1, and the rear end 22 of the buckle piece 2 is driven to bend upward, and the bottom end of the spring 31 is magnetically fixed on the magnet 51 of the rear end 12 of the pedal 1 through the metal bottom plate 61, so that the spring 31 is elastically extended upward by a height G, and the rear end 12 of the pedal 1 and the rear end 22 of the buckle piece 2 are elastically extended from each other. At this time, the rear end 22 of the cleat 2 can also be elastically lifted by the extended spring 31 and drives the rear end 12 of the pedal 1 to elastically move upwards, so that the user can naturally lift and lower the rear edge a2 of the sole a1 along with the circular pedaling motion of the leg, thereby improving the smoothness of riding the bicycle.

As shown in the states (D) to (F) of fig. 7, 9 and 10, when the user hooks the pedal 1 backward F1 and upward F2 to perform the circumferential pedaling motion, the rear end 22 of the blade 2 pushes backward against the inner side of the rear wall 17, so that the rear wall 17 can prevent the blade 2 from separating backward from the pedal 1, thereby further improving the stability of the combination between the blade 2 and the pedal 1.

As shown in fig. 6 and 7, the inner wall of the top of the inserting groove 13 is provided with an inner inclined surface 131, the outer wall of the top of the inserting portion 23 is provided with an outer inclined surface 231 which can contact the inner inclined surface 131, the inner inclined surface 131 and the outer inclined surface 23 are inserted into each other in an L shape which is slightly inclined, and the L-shaped bent angle is arc-shaped, wherein, the included angle between the inner inclined surface 131 and the outer inclined surface 231 of the inserting groove 13 and the horizontal plane is about 65 degrees in the embodiment shown in the figure; however, any angle between the included angles of 55 degrees and 75 degrees can be implemented, when the engaging portion 23 is inserted into the slot 13, the outer inclined surface 231 of the engaging portion 23 just contacts the inner inclined surface 131 of the slot 13, and when the user steps on the pedal 1, the inner inclined surface 131 of the slot 13 can be stopped in front of and above the engaging portion 23, thereby stably positioning the engaging portion 23 in the slot 13. The bottom of the embedding part 23 is provided with a concave surface 232, when the embedding part 23 is embedded into the embedding groove 13, a gap S can be formed between the concave surface 232 and the inner wall of the embedding groove 13, so as to provide the effect that the embedding part 23 arranged on the sole buckle piece 2 is easy to be separated from the embedding groove 13; in other words, the gap S prevents the fitting portion 23 from being fitted into the fitting groove 13 to form an airtight fitting state, which makes the fitting portion difficult to be detached.

It should be noted that, in the present embodiment, by virtue of the stopping function of the mutual engagement between the aforesaid engaging portion 23 and the embedding slot 13 and the stopping function of the aforesaid rear retaining wall 17, the rear end 12 of the pedal 1 only needs to be provided with the magnet 51 with basic magnetic attraction, when the magnet 51 attracts the metal bottom plate 61 at the bottom of the rear end 22 of the buckle piece 2, so as to make the spring 31 elastically extend, the rear retaining wall 17 stops outside the rear end 22 of the buckle piece 2, as mentioned above, when the user hooks the pedal 1, the force of the foot portion upwards F2 and backwards F1 is respectively received by the front stopping function of the mutual engagement between the engaging portion 23 and the embedding slot 13 and the rear stopping function of the rear retaining wall 17, even if the magnet 51 has only limited magnetic attraction, the buckle piece 2 of the user is not separated from the pedal 1, and in addition, due to the stopping function of the aforesaid rear retaining wall 17 and the attracting function of the magnet 51, the embedding part 23 and the embedding groove 13 only need to be mutually embedded by L-shaped slightly inclined parts, and the L-shaped bent part is in a circular arc shape without other tenons or clamping structures; furthermore, the space S formed between the concave surface 232 at the bottom of the engaging portion 23 and the inner wall of the slot 13 can achieve the effect that the engaging portion 23 is easily separated from the slot 13.

In addition, by means of the mutual matching of the above elements, the embedding groove and the embedding part only need to be embedded with each other in an L shape which is basically inclined, and the inclination angle of the L-shaped mutual embedding can be implemented within 55 degrees to 75 degrees. Therefore, when a user wants to stop, get off or get off the bicycle or perform emergency braking during riding the bicycle, the user only needs to lift the foot by natural action to overcome the magnetic force of the magnet, so that the sole buckle piece can be quickly separated from the pedal at any time, and the safety of riding the bicycle can be ensured.

Referring to fig. 11, when a user wants to stop, get off or brake the bicycle, he or she needs to lift the foot (the sole a2, the shoe B, the sole buckle 2) from the pedal 1 and move the foot to the ground, as mentioned above, the magnet 51 only needs to provide a basic magnetic attraction, so the user can drive the sole buckle 2 to be quickly separated from the pedal 1 by overcoming the magnetic force of the magnet 51 with the force of the natural foot lifting action, and lift the foot from the pedal 1 and move the foot to the ground by the natural (intuitive) action, so that the dangerous situations of falling, falling and the like caused by the fact that the prior art does not twist the ankle or does not lift the foot with time to twist the ankle can be avoided, and the safety of the bicycle can be effectively improved.

In summary, the technical feature of the present invention is that the matching between the elastic device 3 (spring 31), the engaging portion 23, the caulking groove 13, the rear wall 17 and the magnet 51 is utilized, so that the magnet 51 only needs to have a basic limit of attraction force to achieve the effect of easy releasing the card at any time, and the attraction force of the magnet can be implemented at any Unit value between 2800 to 4500GS (gaussian Unit).

As shown in fig. 4 and 6, a magnetic conductive metal sheet 8 may be stacked on the magnet 51, and the magnetic attraction of the magnet 51 may be increased according to the actual requirement of the user by means of a magnetic field loop generated between the magnet 51 and the magnetic conductive metal sheet 8.

As shown in fig. 1 to fig. 3, two sides of the rear end 22 of the cleat 2 can also be respectively provided with a retaining portion 27, when the rear end 22 of the cleat 2 is elastically assembled at the rear end 12 of the pedal 1, the retaining portions 27 can be sleeved at two sides of the rear end 12 of the pedal 1, so as to guide the rear end 22 of the cleat 2 to abut against the rear end 12 of the pedal 1.

Referring to fig. 12, in addition, a first assembly 5 (a magnet 51) may be disposed at the bottom of the rear end 22 of the sole buckle piece 2, the bottom end of the elastic device 3 (the spring 31) is fixed at the top of the rear end 12 of the pedal 1, and a second assembly 6 (a metal bottom plate 61) is disposed at the top end of the elastic device 3, the first assembly 5 and the second assembly 6 can be combined with and separated from each other, so that the rear end 12 of the pedal 1 and the rear end 22 of the sole buckle piece 2 can be elastically unfolded and folded, and the rear end 22 of the sole buckle piece 2 can be lifted by the elasticity of the elastic device 3 to further drive the rear end 12 of the pedal 1.

Compared with the prior structure technology, the invention has the following advantages:

the smoothness and the treading efficiency of treading the pedal 1 of the bicycle are improved: a. the foot force efficiency is not wasted, and the effective rate is converted into the riding speed. b. When the bicycle is used for riding on an uphill slope or for a long time, the actual pedaling effect can be sensed. c. The pedal 1 is fixed at the optimal position of the sole of the foot, thereby reducing the fatigue of long-distance riding, continuously maintaining the optimal riding posture and keeping good coordination. d. When a user pedals the pedal 1 forwards and downwards to the state (B) to the state (D) of fig. 10 by carrying out the leg circular stepping motion on the riding bicycle, the stable stepping motion drives the thigh muscle at the front side, so that good correct motion can be maintained; when the user hooks the pedal 1 backward and upward to the state (E) to the state (F) shown in fig. 10, the sole buckle piece 2 magnetically attracts the pedal 1 to lift up through the magnet 51, so as to strengthen the force of the rear side muscle group and disperse the tightening tension of the front side thigh muscle, thereby achieving a good turning and treading effect.

(II) the safety of riding the bicycle is improved: a. the invention relates to a structure for connecting a spring 31 between a sole buckle piece 2 and a pedal 1, which can solve the problem that most people are afraid of entering the field of blocking and pedaling. b. The traditional clamping and treading structure is easy to cause difficult clamping and car falling when a user wants to stop in the riding process. c. When a person entering the door wants to stop, get off or get off the bicycle or perform emergency braking while riding the bicycle, the person is particularly apt to forget to timely disengage the pedal and fall down because the person is not completely familiar with using the pedal, for example: when the traffic light stops, the driver does not pay attention to the separation from the blocking pedal to lose the gravity center, and the left and right feet of the user are unfamiliar with the use of the conventional foot separation from the blocking pedal, so that the conditions such as vehicle falling and the like are easy to occur.

(III) improving the poor riding posture: if the traditional pedal is continuously used, the old pedaling postures of downward heel, eight outward and the like are developed, or the strong force is used for downward pedaling, and the like, so that the knees are easily injured and the feet are easily cramped, and the combined structure of the sole buckle piece 2, the pedal 1 and the elastic device 3 can fix the two feet at the position of the pedal 1, so that the position of the original pedaling habit of a user can be corrected, and the correct riding posture is further ensured.

And (IV) stability and safety are improved: by using the combined structure of the sole buckle piece 2, the pedal 1 and the elastic device 3, even when the shoes meet potholes or unstable road conditions, or climb slopes, overtake and step on with high revolution number, the feet can still be stably fixed on the pedal 1, thus avoiding danger caused by stepping on empty.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
