[0034] An embodiment of the present invention provides a footrest assembly, which is applied to a seat. The specific structure and function of the footrest assembly provided by the embodiment of the present invention will be further described below with reference to text and drawings.

[0035] Reference Figures 1 to 4 According to the first embodiment of the present invention, a pedal assembly includes three major components: a connecting frame 100, a pedal 200, and an adjustment mechanism 300. The connecting frame 100 is composed of a connecting rod 110 and a connecting sleeve 120. The connecting sleeve 120 is fixed to one end of the connecting rod 110, and a side of the connecting sleeve 120 is provided with a receiving cavity 121 for accommodating the adjustment mechanism 300. The pedal 200 includes a connecting post 210 and a support plate 220. The support plate 220 is connected to one side of the connecting post 210 for the user to step on. The connecting post 210 is connected to the connecting sleeve 120 through a rotational connection, allowing the pedal 200 to rotate relative to the connecting sleeve 120. A plurality of shift holes 211 are provided on the side wall of the connecting post 210 facing the receiving cavity 121. The shift holes 211 are spaced apart along the circumference of the connecting post 210 and are designed to cooperate with the shift posts 322 in the adjustment mechanism 300 to lock the pedal 200 at different angles.

[0036] Reference Figures 1 to 4In some embodiments, the adjustment mechanism 300 includes a rotating sleeve 310, a locking member 320, an elastic member 330 and a limiting member 340. The rotating sleeve 310 is arranged in the accommodating cavity 121 and can rotate freely. The rotating sleeve 310 has an axially extending mounting groove 311, and the peripheral wall of the mounting groove 311 is provided with a plurality of first latch teeth 312. The outer peripheral wall of the locking member 320 is provided with a plurality of second latch teeth 321 that cooperate with the first latch teeth 312, and the side of the locking member 320 facing the connecting column 210 is provided with a gear column 322. The locking member 320 and the elastic member 330 are jointly arranged in the mounting groove 311, and the elastic member 330 can continuously push the locking member 320 so that the gear column 322 is inserted into the gear hole 211, thereby achieving the locking of the pedal 200. The limiting member 340 is connected to the rotating sleeve 310 and is used to confine the locking member 320 and the elastic member 330 in the installation groove 311 to ensure the stability of the adjustment mechanism 300.

[0037] To unfold or fold the pedal 200, the user simply rotates the rotating sleeve 310, shifting the first latch 312 and the second latch 321. The first latch 312 pushes the second latch 321, causing the locking member 320 to move away from the connecting post 210, thereby separating the shift post 322 from the shift hole 211. With the shift post 322 separated from the shift hole 211, the pedal 200 can rotate freely, allowing the user to easily unfold the pedal 200 to the desired angle or fold it away.

[0038] The footrest assembly provided by the first embodiment of the present invention simplifies the operation of the footrest 200 during deployment and folding, significantly enhancing the user experience. Specifically, the footrest assembly, through the coordination of the rotating sleeve 310, the locking member 320, the elastic member 330, and the retaining member 340, allows the user to unlock and lock the footrest 200 simply by rotating the rotating sleeve 310. This not only simplifies the operation process but also improves convenience and comfort, effectively avoiding the complex operation and poor user experience associated with conventional chair footrests 200 during deployment and folding.

[0039] Reference Figures 2 to 4 According to the pedal assembly provided by the embodiment of the first aspect of the present invention, a limiting boss 313 is provided on the outer wall of the rotating sleeve 310 to enhance the stability of the rotating sleeve 310 during rotation within the accommodating cavity 121 and prevent it from shifting or falling off during rotation. Accordingly, a limiting groove 122 is provided on the inner wall of the accommodating cavity 121. The limiting groove 122 is arc-shaped and extends along the circumference of the accommodating cavity 121. The limiting groove 122 cooperates with the limiting boss 313 on the rotating sleeve 310 to limit the rotation angle of the rotating sleeve 310.

[0040] When the rotating sleeve 310 is installed in the accommodating cavity 121, the limiting boss 313 accurately engages the limiting groove 122, thereby ensuring the stability and accuracy of the rotating sleeve 310 during rotation. This not only improves the limiting prompt when the user rotates the handle 314, but also makes the user feel a smoother and more stable hand feeling when operating the rotating sleeve 310.

[0041] Reference Figures 2 to 4 According to the pedal assembly provided by the embodiment of the first aspect of the present invention, the outer wall of the rotating sleeve 310 is provided with two limiting bosses 313. The two limiting bosses 313 are symmetrically arranged to ensure the balance and stability of the rotating sleeve 310 within the accommodating cavity 121. Correspondingly, the inner wall of the accommodating cavity 121 is also provided with two limiting grooves 122. These two limiting grooves 122 correspond one-to-one with the two limiting bosses 313 on the rotating sleeve 310, thereby ensuring the coordination between the rotating sleeve 310 and the accommodating cavity 121.

[0042] It is understood that during installation, the two limiting bosses 313 on the rotating sleeve 310 will respectively snap into the two limiting grooves 122 on the inner wall of the accommodating cavity 121, thereby ensuring that the rotating sleeve 310 will not shift or fall off during rotation. This symmetrical arrangement of the limiting bosses 313 and limiting grooves 122 not only improves the overall structural strength of the pedal assembly, but also makes the rotating sleeve 310 rotate more smoothly and stably, further enhancing the user experience.

[0043] Reference Figure 2 According to the pedal assembly provided by the embodiment of the first aspect of the present invention, the locking member 320 is provided with two shift posts 322. These two shift posts 322 can enhance the connection stability between the locking member 320 and the connecting post 210, ensuring that the pedal 200 can be securely locked in the desired position during the unfolding or folding process. Accordingly, the connecting post 210 is provided with shift holes 211 that cooperate with the two shift posts 322. Each shift post 322 can accurately snap into a shift hole 211. When the user rotates the rotating sleeve 310, causing the first latch 312 to be misaligned with the second latch 321, thereby pushing the locking member 320 to move, the two shift posts 322 will simultaneously disengage from the corresponding shift holes 211, allowing the pedal 200 to rotate. When the user needs to lock the pedal 200 at a certain angle, the user loosens the rotating sleeve 310. Under the push of the elastic member 330, the rotating sleeve 310 can rotate in the opposite direction, so that the first latch tooth 312 and the second latch tooth 321 are re-engaged, and the two gear posts 322 are again inserted into the corresponding gear holes 211, thereby achieving a secure locking of the pedal 200.

[0044] Reference Figures 2 to 4According to the pedal assembly provided by the embodiment of the first aspect of the present invention, a load-bearing plate 350 is provided in the mounting groove 311, and the elastic member 330 is in the form of a spring, one end of the spring abuts against the load-bearing plate 350, and the other end abuts against the locking member 320. When it is necessary to lock the pedal 200, the spring is in a compressed state, and its elastic force pushes the locking member 320, so that the gear column 322 is firmly engaged in the gear hole 211. When the user rotates the rotating sleeve 310 to unlock the pedal 200, the misalignment of the first latch 312 and the second latch 321 causes the locking member 320 to be pushed, and the spring will be further compressed, allowing the gear column 322 to disengage from the gear hole 211. The load-bearing plate 350 and the spring are designed to cooperate, and the elastic force of the spring is transferred to the rotating sleeve 310 through the load-bearing plate 350, avoiding the elastic force of the spring directly passing through the limit member 340 and causing the limit member 340 to detach. This not only ensures the stable installation of the elastic member 330 in the installation groove 311, but also improves the locking force and unlocking smoothness of the pedal assembly.

[0045] Reference Figure 3 According to the pedal assembly provided by the embodiment of the first aspect of the present invention, a receiving groove is provided on the side of the locking member 320 facing the spring. When the spring is installed in the installation groove 311, one end of the spring abuts against the load-bearing plate 350, while the other end accurately abuts against the bottom wall of the receiving groove on the locking member 320. This design not only ensures that the spring can stably transmit elastic force during compression and release, but also prevents possible sliding or deviation between the spring end and the locking member 320, thereby improving the stability and reliability of the locking mechanism.

[0046] As can be appreciated, the tight fit between the receiving slot and the spring end allows for smoother and more accurate locking and unlocking of the footrest 200 during its unfolding or folding. The user simply needs to gently rotate the rotating sleeve 310 to easily lock and unlock the footrest 200, without worrying about operational errors caused by spring slippage or deflection.

[0047] Referring to Figure 3, in the pedal assembly according to the embodiment of the first aspect of the present invention, a first connecting post 210 is provided in the middle of the load-bearing plate 350, and a second connecting post 210 is provided in the middle of the receiving groove on the locking member 320. The cooperation between the first connecting post 210 and the second connecting post 210 provides a stable and precise installation position for the spring, ensuring that the spring maintains a stable shape and elastic force during compression and release.

[0048] When the spring is installed in the installation slot 311, its two ends are respectively mounted on the first connecting post 210 and the second connecting post 210. This not only makes the connection between the spring, the bearing plate 350, and the locking member 320 more secure and stable, but also prevents the spring from twisting or deforming during the compression process, thereby improving the reliability and durability of the locking mechanism.

[0049] Furthermore, the coordination between the first and second connecting posts 210 and 220 allows the spring to stably transmit elastic force during the unfolding and folding of the pedal 200, ensuring smooth and accurate locking and unlocking operations. The user simply rotates the rotating sleeve 310, and the spring force pushes the locking member 320 to lock and unlock the pedal 200, eliminating the risk of operational errors caused by an unstable spring connection.

[0050] Reference Figure 1 、 Figure 2 and Figure 4 According to the pedal assembly provided by the first embodiment of the present invention, the rotating sleeve 310 is connected to the handle 314. The connection between the handle 314 and the rotating sleeve 310 can be fixed or detachable, ensuring that the user can conveniently operate the pedal assembly in different usage scenarios. When the user needs to unfold or fold the pedal 200, they only need to grasp the handle 314 and apply an appropriate rotational force, which will cause the handle 314 to rotate the rotating sleeve 310, thereby locking and unlocking the pedal 200.

[0051] The addition of the handle 314 not only improves the ease of operation of the pedal assembly, but also enables the user to more accurately control the rotation angle and force of the rotating sleeve 310 during operation, thereby avoiding damage to the pedal 200 or injury to the user due to improper operation.

[0052] Reference Figure 4 According to the pedal assembly provided by the first embodiment of the present invention, the handle 314 and the rotating sleeve 310 are integrally formed. This integral design not only improves the connection strength and stability between the handle 314 and the rotating sleeve 310, but also avoids operational errors or safety hazards caused by a weak or loose connection. Because the handle 314 and the rotating sleeve 310 are integral, the user can directly and accurately rotate the rotating sleeve 310 when operating the handle 314, thereby locking and unlocking the pedal 200.

[0053] According to the second embodiment of the present invention, a chair is provided, including a footrest assembly as in the first embodiment of the present invention. The main structure of the chair can be any conventional design, such as a backrest, seat, and legs, while the footrest assembly serves as an additional component of the chair, providing the user with more comfortable and convenient foot support. When the user needs to rest or relax, the footrest assembly can be unfolded and the footrest 200 can be locked in the desired position by rotating the rotating sleeve 310 (which can be operated by the handle 314). When the user no longer needs the footrest 200, the footrest assembly can be easily folded and stored to save space.

[0054] Because the footrest assembly adopts the design of the embodiment of the utility model, it has the advantages of stability, reliability, and easy operation, and can provide users with a more comfortable and safe seat experience. At the same time, the overall structure and appearance of the seat can also be customized according to the needs and preferences of the user to meet the needs of different scenarios and uses.

[0055] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
