[0002] The pedal component is one of the essential parts of a bicycle. It is installed on the left and right cranks of the bicycle's middle shaft component. It is a device that converts horizontal force into rotational force. When riding a bicycle, the pedal force is first transmitted to the pedal component, and then the pedal component rotates the crank, the tooth plate, the middle shaft, the chain flywheel, and the rear wheel rotates, so that the bicycle moves forward. The existing bicycle pedal components cannot minimize the horizontal space occupied by the bicycle when the bicycle is not in use, even if the bicycle pedal is foldable.

[0003] Although there are more and more types of bicycle pedals on the market that are designed to reduce space occupation, in general, not only are the types relatively single and unable to meet the personalized needs of consumers; but there is also no bicycle pedal that can be disassembled and assembled very easily and conveniently.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations. Example 1

[0026] Combination Figure 1 and Figure 7 As shown, the utility model discloses a pedal assembly with a quick-disassembly and quick-assembly structure, including a crank 100 and a pedal member 200. The pedal member 200 is assembled and matched with the crank 100 through a disassembly and assembly assembly, which can facilitate the quick disassembly and installation of the pedal member 200.

[0027] In the specific structure, the disassembly and assembly components include an assembly seat 300 and a limiting member 400, the pedal member 200 includes a pedal body 210 and a pedal shaft 220, the pedal body 210 is usually a pedal structure, the pedal shaft 220 is installed in cooperation with the pedal body 210, and is usually a fixed structure, the pedal shaft 220 is extended to one side, and an assembly hole 110 is provided on the crank 100, and the pedal shaft 220 is used to combine with the assembly seat 300 and the assembly hole 110 on the crank 100 to achieve a matching installation; wherein, the assembly seat 300 includes a mounting portion 310, an assembly portion 320 and a limiting matching portion 330, the assembly portion 320 is used to correspond to the assembly hole 110, the mounting portion 310 and the limiting matching portion 330 protrude from the outside of the assembly hole 110 respectively, and the mounting portion 310 usually has flat surfaces on both sides for the convenience of a wrench During the installation operation, a shaft sleeve hole 340 is also provided in the assembly seat 300, and the pedal shaft 220 passes through the shaft sleeve hole 340 and extends to the outside, and the limiting member 400 completes the limiting cooperation between the limiting cooperation portion 330 and the pedal shaft 220; usually the assembly seat 300 is embedded in the assembly hole 110 to achieve matching installation. Preferably, the assembly hole 110 is an internal threaded hole, and the assembly portion 320 on the assembly seat 300 is an external threaded portion. Through the threaded cooperation between the assembly portion 320 and the assembly hole 110, the assembly seat 300 and the assembly hole 110 can be fixedly matched. The pedal shaft 220 directly passes through the shaft sleeve hole 340 to achieve rotational cooperation with the assembly seat 300. The pedal shaft 220 passes through the shaft sleeve hole 340 and extends to the outside of the other end, and the limiting cooperation is achieved in combination with the limiting cooperation portion 330 and the limiting member 400.

[0028] In combination with the above, the limit member 400 includes a first limit seat 410 and a second limit seat 420, and the first limit seat 410 and the second limit seat 420 can be docked and matched with each other. After the first limit seat 410 and the second limit seat 420 are docked, a limit cavity 450 is formed. The first limit seat 410 is provided with a limit protrusion 411, and the second limit seat 420 is provided with a limit spring 440; the limit member 400 is preferably divided into an upper and lower part, and can also be provided on the left and right sides. Using the split assembly structure of the limit member 400, the limit matching part 330 can be covered and assembled, and the limit cavity 350 is used to accommodate the limit matching part 330.

[0029] Among them, a first locking hole 412 is provided on the first limiting socket 410, and a second locking hole 422 is provided on the second limiting socket 420. The first locking hole 412 and the second locking hole 422 correspond to each other. The first locking hole 412 and the second locking hole 422 realize the docking and locking of the first limiting socket 410 and the second limiting socket 420 through the fastener 430, which is convenient for the combined installation of the limiting member 400; a spring seat 421 is provided on the second limiting socket 420, one end of the limiting spring 440 is engaged with the spring seat 421, and the other end is used to abut against the outer wall of the limiting assembly part 330. Preferably, a spring groove 333 is provided at the bottom of the limiting assembly part 330, and the spring groove 333 is used for the abutment and cooperation of the end of the limiting spring 440. The limiting spring 440 structure is added to cooperate with the limiting assembly part 330, which is convenient for resetting after pressing the assembly operation and convenient for disassembly.

[0030] Preferably, an anti-slip pattern 423 is provided on the outer side wall of the second limiting socket 420 to facilitate disassembly and installation operations and prevent components from sliding.

[0031] In combination with the above, a limiting hole 331 is provided on the limiting assembly part 330, and the limiting hole 331 is connected with the shaft sleeve hole 340, and the limiting hole 331 is used to be engaged with the limiting clamping protrusion 411, and a limiting plane 332 is provided on the side wall of the limiting assembly part 330 to be engaged with the limiting cavity 350 in the limiting member 300. The side wall of the limiting cavity 350 is usually also a plane structure, which can prevent the limiting member 300 from rotating; the pedal shaft 220 includes an engaging portion 221, a shaft body 222 and an end cap 224, and the shaft body 222 is used to engage with the limiting convex 411. The shaft sleeve hole 340 corresponds to the engagement portion 221, which is used to abut against the outer wall of the shaft sleeve hole 340. The end cap 224 passes through the shaft sleeve hole 340 and extends to the outside. The shaft body 222 is provided with a shaft groove 223, which is used to correspond to the limiting hole 331 and to be engaged with the limiting protrusion 411 to limit the axial movement of the shaft body 222. The downward limitation of the limiting protrusion 411 is used to limit the shaft groove 223, so that the shaft body 222 cannot be disengaged, and the structure does not affect the rotation of the pedal shaft 220.

[0032] In combination with the above, the end cap 224 is located outside the limiting member 400 , and when the first limiting socket 410 and the second limiting socket 420 complete the limiting locking, the end cap 224 cannot be separated from the limiting cavity 450 .

[0033] Combined with the above structure, if the entire disassembly is required, the user only needs to separate the corresponding fasteners 430, usually screws, in the first locking hole 412 and the second locking hole 422, and combine the limit spring 440 to facilitate the separation of the first limit socket 410 and the second limit socket 420 from the limit assembly part 330, thereby contacting the restriction on the rotating shaft body 222, making it convenient to pull the pedal rotating shaft 220 out of the assembly seat 300 to achieve disassembly.

[0034] If the user needs to quickly disassemble the pedal member 200, the user only needs to lift and press the limit member 400. Usually, the user lifts up against the anti-slip groove 423 to move the entire limit member 400 upward, thereby disengaging the limit protrusion 411 from the shaft groove 223. At this time, the user can quickly remove the pedal member 200 from the shaft sleeve hole 340 by pulling it out axially to achieve disassembly.

[0035] The utility model utilizes the mutual cooperation between the pedal shaft, the assembly part and the limit part, and specially optimizes the design of the limit assembly part in the assembly part combined with the structure of the limit part, so that the overall disassembly and assembly thereof is convenient, and the pedal is convenient for quick disassembly and assembly, thereby improving the convenience of use.
