[0002] With the rise of fitness awareness, various types of fitness equipment have become widely used in homes and commercial fitness facilities. Such equipment often features a foldable or collapsible pedal assembly to reduce space usage when not in use. However, existing pedal folding mechanisms often suffer from the following drawbacks: First, they lack a locking function. Conventional pedals rely solely on friction between the rotating shaft and the bracket to maintain their relative position when folded, lacking a reliable mechanical locking mechanism. When the fitness equipment is impacted or vibrated, the pedal assembly may accidentally unfold, causing injury to the user or surrounding objects, or even damage to the fitness equipment itself, posing a safety hazard. Second, the unlocking mechanism is complex and inconvenient to operate. Some improvements may incorporate a locking mechanism, but these complex structures, employing complex structures such as multiple links or electromagnetic locks, not only increase production costs and assembly difficulty but also can cause locking failure due to component wear or circuit failure. During the unlocking process, the user must manually toggle an additional switch or knob, making the unlocking process inconvenient. This is particularly problematic in scenarios where the user needs to hold the pedal assembly or the fitness equipment itself, where both hands are occupied. This manual unlocking design is significantly inconvenient and significantly reduces the user experience. Summary of the Invention

[0018] The preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0019] like Figures 1 to 4 As shown, this embodiment provides a pedal folding and unlocking device, including: a mounting base 1, a pedal mounting assembly 2 and a pedal locking assembly 3, wherein the pedal locking assembly 3 is arranged next to the pedal mounting assembly 2; the pedal mounting assembly 2 includes a pedal shaft 21 and a pedal connecting member 22, the pedal connecting member 22 is rotatably arranged on both sides of the mounting base 1 through the pedal shaft 21, and the pedal connecting member 22 rotates synchronously with the pedal shaft 21; a locking groove 211 is provided on the pedal shaft 21; the pedal locking assembly 3 includes a connected locking member 31 and a foot pedal 32, and a claw 311 is provided at one end of the locking member 31 away from the foot pedal 32; the position and shape of the claw 311 are respectively matched with the position and shape of the locking groove 211, that is, when the pedal assembly 4 is in the folded state, the claw 311 can be locked in the locking groove 211; when the pedal assembly 4 is in the intermediate state or the unfolded state, the claw 311 is disengaged from the locking groove 211.

[0020] like Figures 9 to 11As shown, when the pedal mounting assembly 2 is in the folded state, the claw 311 is locked into the locking groove 211, and the locking member 31 is used to lock the pedal shaft 21; Figures 5 to 8 As shown, when the pedal 32 is subjected to force so that the claw 311 disengages from the locking groove 211, the locking effect of the locking member 31 on the pedal shaft 21 is released. At this time, the pedal mounting assembly 2 is transformed into an intermediate state or an expanded state.

[0021] The mounting base 1 described in this embodiment refers to the base structure of the fitness equipment. The pedal mounting assembly 2 refers to the mounting structure of the pedal assembly 4, and the pedal assembly 4 is simply referred to as the pedal; wherein the pedal connector 22 refers to the structure for mounting and connecting the pedal assembly 4, the pedal shaft 21 refers to the rotating shaft of the pedal connector 22 and the pedal assembly 4, and the locking groove 211 refers to the arc-shaped groove structure of the pedal shaft 21, which is used to cooperate with the claw 311 to assist in locking. The pedal locking assembly 3 refers to a structural assembly that locks the pedal mounting assembly 2 (i.e., the pedal assembly 4) in the folded state, wherein the locking member 31 refers to the structural member for locking the pedal shaft 21, the footrest 32 refers to the footrest structural member connected to the locking member 31, and the claw 311 refers to the buckle end that can be snapped into the locking groove 211. The folded state refers to the storage state when the pedal assembly 4 is folded and lifted to the frame structure of the fitness equipment, such as Figure 9 and Figure 10 The unfolded state refers to the state in which the pedal assembly 4 is unfolded and put down for the user to use. Figure 5 and Figure 6 The intermediate state refers to the state corresponding to the intermediate transition process between the folded state and the unfolded state, as shown in Figure 7 and Figure 8 shown.

[0022] In the pedal mounting assembly 2 of this embodiment, the pedal connector 22 is rotatably mounted on both sides of the mounting base 1 via the pedal shaft 21. The pedal connector 22 rotates synchronously with the pedal shaft 21. That is, during the rotation of the pedal assembly 4 and the pedal connector 22, the pedal shaft 21 also rotates synchronously. A locking groove 211 is provided on the pedal shaft 21. The locking member 31 of the pedal locking assembly 3 is provided with a claw 311. The position and shape of the claw 311 match those of the locking groove 211, allowing it to be snap-fitted into the locking groove 211.

[0023] like Figures 9 to 11As shown, when the pedal mounting assembly 2 is in the folded state, the claw 311 is locked into the locking groove 211, and the locking member 31 can lock the pedal shaft 21 through the cooperation between the claw 311 and the locking groove 211. The overall structure of this embodiment is simple and easy to implement, which effectively avoids the problem of accidental expansion of the pedal assembly and improves the safety performance of the fitness equipment. On this basis, Figures 5 to 8 As shown, when the pedal 32 is subjected to force (such as when the user steps on the pedal 32), the claw 311 can be disengaged from the locking groove 211, so as to release the locking effect of the locking member 31 on the pedal shaft 21. Therefore, the user's hands can be well freed during the unlocking process of the pedal, which effectively improves the convenience of pedal unlocking and enhances the user's experience.

[0024] like Figures 1 to 4 As shown, the pedal mounting assembly 2 described in this embodiment also includes a bearing 23 and a limit member 24, and the limit member 24 refers to a block-shaped limit structure that rotates following the rotation of the pedal shaft 21, and the limit member 24 is coaxial with the pedal shaft 21 and rotates synchronously; a limit platform 11 is provided on the inner side of the mounting base 1, and the limit platform 11 refers to a block-shaped structure for limiting the limit member 24; the pedal connecting member 22 is connected to the limit member 24 through the pedal shaft 21 and the bearing 23, and the position of the limit member 24 corresponds to the position of the limit platform 11. When the pedal mounting assembly 2 is in the folded state, the limit member 24 conflicts with the limit platform 11, thereby achieving the limitation of the limit member 24. At this time, in fact, it is also equivalent to achieving the limiting effect on the pedal shaft 21.

[0025] Therefore, in the folded state, this embodiment realizes the locking effect of the pedal shaft 21 on the outer side of the mounting base 1 through the cooperation between the claw 311 and the locking groove 211; and on the inner side of the mounting base 1, the pedal shaft 21 is limited by the cooperation between the limit member 24 and the limit platform 11, thereby effectively avoiding the problem of damage to the device caused by excessive folding of the pedal assembly 4 during the folding process, further improving the safety and reliability of the fitness equipment.

[0026] like Figure 2 As shown, the limiting platform 11 of this embodiment adopts a right-angled trapezoidal limiting structure, and the limiting member 24 is disposed on one side of the right-angled side of the right-angled trapezoidal limiting structure. In other words, the limiting platform 11 can utilize the right-angled side of the right-angled trapezoidal limiting structure to limit the limiting member 24, so that its contact surface is a vertical surface, thereby ensuring the reliability of the limiting structure.

[0027] like Figure 1and Figure 2 As shown, the pedal shaft 21 of this embodiment is arranged on the outside of the mounting base 1, and the limiting member 24 is arranged on the inside of the mounting base 1, so that the outer space and the inner space of the mounting base 1 can be used to play the role of locking and limiting respectively, and can cooperate with each other without interfering with each other, thereby improving the rationality and utilization of its space design.

[0028] like Figure 1 and Figure 2 ,as well as Figure 5 and Figure 6 As shown, the mounting base 1 of this embodiment further includes a base side cover 12, which refers to a cover / shell structure disposed on both sides of the mounting base 1. The pedal shaft 21 and the locking member 31 are disposed between the base side cover 12 and the mounting base 1, and the footrest 32 is disposed through the bottom of the base side cover 12. Therefore, from the user's end, what actually is seen is the footrest 32 protruding through, while the pedal shaft 21 and the locking member 31 are placed within the base side cover 12 to prevent unnecessary exposure of components.

[0029] like Figure 4 As shown, the inner side of the locking member 31 of this embodiment is provided with a locking mounting seat 312, and the locking mounting seat 312 is provided on both sides of the mounting base 1 and is provided below the side of the pedal shaft 21 to achieve the installation and fixation of the locking member 31. Preferably, as Figure 3 As shown, the locking member 31 of this embodiment is also provided with an arc groove 313, and the arc groove 313 is arranged on the inner side of the claw 311. The design of the arc groove 313 can provide a certain deformable space for the claw 311; the locking member 31 is also provided with a contact end 314, and the contact end 314 is arranged on the side of the locking member 31 close to the pedal shaft 21, and is arranged below the claw 311, for resisting the pedal shaft 21 at the bottom to play a bottom limiting role.

[0030] like Figures 5 to 10 As shown, the present invention further provides a fitness equipment, comprising a pedal assembly 4 and the pedal folding, locking and unlocking device as described above, wherein the pedal assembly 4 is connected to the mounting base 1 through the pedal mounting assembly 2 .

[0031] Preferably, the mounting base 1 in this embodiment adopts a trapezoidal base structure to ensure the stability of the mounting base 1 when placed on the ground; the pedal assembly 4 is arranged on the hypotenuse side of the trapezoidal base structure to facilitate the rotation and folding of the pedal assembly 4.

[0032] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
