Description
Technical Field
[0001] The present invention relates to a pedal connection structure, in particular to a pedal locking structure for fitness equipment, and further to fitness equipment adopting the pedal locking structure. Background Art
[0002] In today's society, as people's health awareness continues to rise, fitness equipment is becoming increasingly common in both homes and gyms. Among these, fitness equipment with retractable pedals is highly sought after due to its ease of transportation and storage. However, existing fitness equipment with retractable pedals presents several technical challenges that urgently need to be addressed.
[0003] The common fitness equipment pedals on the market can be folded up when not in use to facilitate transportation and storage and save space. However, in actual use, when the pedals are unfolded, they are not equipped with a corresponding locking structure. This makes the pedals unstable during use. At this time, if some exercises that require both feet to step on the pedals for strength training or balance training, such as squats, lunges, and single-leg standing, the instability of the pedals will greatly affect the training effect and may even cause the user to lose balance and fall, causing physical injury. This potential safety hazard not only reduces the user experience of fitness equipment, but also limits its application in some high-intensity or high-difficulty training scenarios. In addition, different users have different strengths and methods when using fitness equipment. Pedals without a locking structure are difficult to adapt to various usage situations and cannot provide users with a stable and reliable support platform. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a pedal locking structure for fitness equipment. The invention aims to effectively lock and unlock the pedals through an optimized structural design, providing a stable and reliable support platform for the user, thereby improving the stability and safety of the fitness equipment during use. Furthermore, the present invention also provides a fitness equipment that utilizes this pedal locking structure.

When the pedal is in the folded state and the intermediate state of the unfolded state, the first limiting protrusion of the cam module is located on the outside of the arc-shaped groove, and the protrusion can move in the arc-shaped groove following the rotation of the pedal; when the pedal is in the unfolded state, the protrusion follows the rotation of the pedal and moves to the bottom of the arc-shaped groove. At this time, the cam module rotates until at least part of the first limiting protrusion rotates into the arc-shaped groove and is located above the protrusion, so as to lock the pedal by limiting the protrusion by the first limiting protrusion.
[0006] A further improvement of the present invention is that the cam module also includes a camshaft, an operating rod, a bearing and a base, the camshaft is arranged in the base through a bearing, the base is fixedly set in the chassis body, the operating rod is fixedly set on the camshaft, and the first limiting protrusion is set at one end of the camshaft close to the pedal connection module.

[0009] A further improvement of the present invention is that the switch detection module includes a switch circuit board and a spring switch, the spring switch is arranged on the switch circuit board and below the second limit protrusion; when the pedal is in a state intermediate between the folded state and the unfolded state, the second limit protrusion is separated from the spring switch; when the pedal is in the unfolded state, at least a portion of the second limit protrusion presses the spring switch.
[0010] A further improvement of the present invention is that when the pedal needs to be adjusted from the expanded state to the expanded intermediate state or the folded state, the camshaft is first rotated by the operating lever so that the first limiting protrusion leaves the arc-shaped groove, thereby releasing the limiting effect of the first limiting protrusion on the protrusion, thereby unlocking the pedal.
[0011] A further improvement of the present invention is that a turntable is also provided on the chassis connection module, and the turntable is arranged on the inner side of the arc-shaped groove; the first end of the pedal connector is connected to the turntable through a connecting shaft, and the second end of the pedal connector is connected to the pedal, and the protrusion is arranged between the first end and the second end of the pedal connector.

[0019] The preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0020] like Figures 1 to 13As shown, this embodiment provides a pedal locking structure for fitness equipment, comprising: a pedal connection module 1, a chassis connection module 2, and a cam module 3. The pedal connection module 1 includes a pedal connection member 11 and a protrusion 12, wherein the protrusion 12 is fixedly disposed on the inner side of the pedal connection member 11; the chassis connection module 2 is disposed on the side of the chassis body 4 of the fitness equipment, and is provided with an arcuate groove 21, which is preferably disposed on the outer side of the chassis connection module 2. The protrusion 12 is slidably disposed in the arcuate groove 21; that is, the protrusion 12 can move in the arcuate groove 21. The cam module 3 passes through the chassis body 4 and is connected to the chassis connection module 2. The cam module 3 is provided with a first limiting protrusion 31 on one end thereof near the pedal connection module 1. The first limiting protrusion 31 is rotatably arranged between the outer side and the lower middle part of the arc-shaped groove 21. Specifically, the cam module 3 is provided with a cam shaft 32. The cam shaft 32 is provided with a first limiting protrusion 31 at one end close to the pedal connection module 1. When the cam shaft 32 rotates, the relative position between the first limiting protrusion 31 and the arc-shaped groove 21 can be changed, for example, respectively. Figure 2 、 Figure 7 and Figure 10 shown.
[0021] The pedal connection module 1 in this embodiment refers to a structural component for connecting the pedal 5. The chassis connection module 2 refers to a connecting structural component installed on the side of the chassis body 4. The cam module 3 refers to a cam structure for achieving connection and locking effects, such as Figure 4 and Figure 5 shown.
[0022] like Figure 12 As shown, both ends of the pedal 5 of the fitness equipment in this embodiment are connected to the chassis body 4 through the pedal connection module 1 and the chassis connection module 2; Figures 1 to 3 as well as Figures 6 and 7 As shown, when the pedal 5 is in the intermediate state between the folded state and the unfolded state, the first limiting protrusion 31 of the cam module 3 is located outside the arc-shaped groove 21, as shown in FIG. Figure 2 and Figure 7 As shown, the protrusion 12 can move in the arc groove 21 following the rotation of the pedal 5. Figure 9 and Figure 10As shown, when the pedal 5 is in the expanded state, the protrusion 12 follows the rotation of the pedal 5 and moves to the bottom of the arc-shaped groove 21. At this time, the cam module 3 rotates until at least part of the first limiting protrusion 31 rotates into the arc-shaped groove 21 (that is, the first limiting protrusion 31 rotates to the middle and lower part of the arc-shaped groove 21) and is located above the protrusion 12, so as to lock the pedal 5 by limiting the protrusion 12 through the first limiting protrusion 31.
[0023] In this embodiment, the pedal 5 is in the folded state, which means that the pedal 5 is completely folded up. Figure 1 The pedal 5 is in the middle state of expansion, which means that the pedal 5 is in the state between the folded state and the expanded state, as shown in FIG. Figure 6 The pedal 5 is in the unfolded state, which means the pedal 5 is in the fully unfolded state. Figure 9 and Figure 12 shown.
[0024] like Figure 4 and Figure 5 As shown, preferably, the cam module 3 of this embodiment further includes a camshaft 32, an operating rod 33, a bearing 34 and a base 35, the camshaft 32 is arranged in the base 35 through the bearing 34, the base 35 is fixedly arranged in the chassis body 4, and the operating rod 33 is fixedly arranged on the camshaft 32, so that the rotation operation of the camshaft 32 can be achieved through the operating rod 33; the first limiting protrusion 31 is arranged at one end of the camshaft 32 close to the pedal connection module 1, so as to achieve the avoidance or limiting effect on the protrusion 12 in different states, that is, when the pedal 5 is in the folded state and the intermediate state of the unfolded state, the first limiting protrusion 31 will not hinder the movement of the protrusion 12; when the pedal 5 is in the unfolded state, the first limiting protrusion 31 limits the protrusion 12 to limit the movement of the protrusion 12.
[0025] like Figure 12 and Figure 13 As shown, the chassis connection module 2 in this embodiment is provided with an operating window 23, and the operating rod 33 passes through the operating window 23, so that the setting of the operating rod 33 can be realized within a limited space. The operating rod 33 is equivalent to a limiting handle, which is convenient for the user to change the relative position between the protrusion 12 and the first limiting protrusion 31 according to actual needs.
[0026] More preferably, Figure 3 、 Figure 8 and Figure 11As shown, this embodiment also includes a switch detection module 6, which is arranged in the chassis body 4; the cam module 3 also includes a second limiting protrusion 36, which is arranged at the end of the cam module 3 away from the pedal connection module 1, and the second limiting protrusion 36 is arranged above the switch detection module 6; that is, limiting protrusion structures are provided at both ends of the cam shaft 32, and at the end close to the pedal connection module 1, there is a first limiting protrusion 31 for limiting or avoiding the protrusion 12; at the end away from the pedal connection module 1, there is a second limiting protrusion 36 for triggering the switch detection module 6, so as to reuse the same cam shaft 32 and improve the humanized design of the product.
[0027] like Figure 3 and Figure 8 As shown, when the pedal 5 is in the intermediate state between the folded state and the unfolded state, the second limiting protrusion 36 is separated from the switch detection module 6; at this time, the switch detection module 6 will not be triggered. Figure 11 As shown, when the pedal 5 is in the unfolded state, at least a portion of the second limiting protrusion 36 presses the switch detection module 6, and while locking the pedal 5, a switch signal is sent through the switch detection module 6.
[0028] The reason for this design of this embodiment is that a detection switch for synchronization with the locking of the pedal 5 is provided in the chassis body 4. After the cam module 3 locks the pedal 5, the second limiting protrusion 36 of the cam shaft 32 (equivalent to the inner cam structure) will press the switch detection module 6, thereby activating the main board of the fitness equipment and performing strength adjustment; when the cam module 3 does not lock the pedal 5, the strength adjustment of the main board will not be activated, which can effectively avoid the risk of the product overturning during heavy weight training because the pedal 5 is not locked.
[0029] Preferably, the switch detection module 6 of this embodiment includes a switch circuit board 61 and a spring switch 62, wherein the spring switch 62 is provided on the switch circuit board 61 and below the second limit protrusion 36; Figure 8 As shown, when the pedal 5 is in the intermediate state between the folded state and the unfolded state, the second limit protrusion 36 is separated from the spring switch 62; Figure 11 As shown, when the pedal 5 is in the unfolded state, at least a portion of the second limiting protrusion 36 presses the spring switch 62 .
[0030] Preferably, in this embodiment, when the pedal 5 needs to be adjusted from the expanded state to the expanded intermediate state or the folded state, the cam shaft 32 is first rotated by the operating rod 33, so that the first limiting protrusion 31 leaves the arc-shaped groove 21, and the limiting effect of the first limiting protrusion 31 on the protrusion 12 is released, thereby unlocking the pedal 5. The whole process is simple and easy to operate.
[0031] like Figure 2 As shown, the chassis connection module 2 of this embodiment is further provided with a turntable 22, and the turntable 22 is provided on the inner side of the arc-shaped groove 21; Figure 13 As shown, the first end of the pedal connector 11 is connected to the turntable 22 via a connecting shaft 13, and the second end of the pedal connector 11 is connected to the pedal 5. The protrusion 12 is provided between the first and second ends of the pedal connector 11. The first end of the pedal connector 11 refers to the end of the pedal connector 11 away from the pedal 5, and the second end of the pedal connector 11 refers to the end of the pedal connector 11 close to the pedal 5. The provision of the turntable 22 and the connecting shaft 13 can better enhance the connection stability between the pedal connection module 1 and the chassis connection module 2.
[0032] Preferably, Figure 3 and Figure 8 As shown, the second end of the pedal connector 11 in this embodiment is provided with a serration structure. Such a serration structure can enhance the connection stability between the pedal connection module 1 and the pedal 5 .
[0033] Preferably, Figure 2 As shown, the bump 12 of this embodiment adopts a rounded block structure. The rounded block structure refers to a block-shaped structure with rounded corners. The reason for this setting is that the rounded corner design ensures the smooth movement of the bump 12. In addition, the block structure is not a whole cylindrical structure, which can ensure the reliability of the first limiting protrusion 31 in limiting the bump 12.
[0034] like Figure 1 、 Figure 6 、 Figure 9 and Figure 12 As shown, this embodiment further provides a fitness equipment, including the pedal locking structure for fitness equipment as described above, and including a chassis body 4 and a pedal 5, wherein the pedal 5 is arranged on the chassis body 4 through the pedal locking structure.
[0035] To sum up, this embodiment designs a matching pedal connection module 1, chassis connection module 2 and cam module 3, and a protrusion 12 is fixedly arranged on the inner side of the pedal connection part 11 of the pedal connection module 1; an arc-shaped groove 21 corresponding to the protrusion 12 is arranged on the chassis connection module 2; a first limiting protrusion 31 is arranged at one end of the cam module 3 close to the pedal connection module 1, and the first limiting protrusion 31 is rotatably arranged between the outer side and the lower middle part of the arc-shaped groove 21, so that during the rotation of the pedal 5 of the fitness equipment, the relative position relationship between the protrusion 12 and the first limiting protrusion 31 is used to realize the locking and unlocking of the pedal 5, thereby providing a stable and reliable support platform for the user, and effectively improving the stability and safety of the fitness equipment during use.
[0036] 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.
