Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 5 One embodiment of this utility model provides a foot pedal assembly, comprising: Mounting base 10 is used to install on an office chair. In this embodiment, the mounting base 10 is installed under the seat of the office chair as an example. The telescopic module 20 has a telescopic mechanism that is movably connected to the mounting base 10 and can extend or retract relative to the mounting base 10. The pedal module 30 is rotatably mounted on the telescopic module 20, and an elastic element 31 is provided between the pedal module 30 and the telescopic module 20.

[0021] The working principle of the foot pedal assembly according to one embodiment of the present invention is explained below: The pedal module 30 can be retracted under the seat of the office chair relative to the mounting base 10 via the telescopic module 20, or it can extend to the front of the seat relative to the mounting base 10. After the pedal module 30 extends to the front of the seat, the user's feet can be placed on the pedal module 30. Based on the human posture, the legs are usually placed on the side of the pedal module 30 away from the mounting base 10. Therefore, the feet will cause the pedal module 30 to rotate downward in the direction away from the mounting base 10. At this time, the elastic element 31 will be driven by the pedal module 30 to produce elastic deformation. During the process of elastic deformation, the elastic element 31 provides cushioning for the pedal module 30, and thus provides cushioning for the user's legs, resulting in a better user experience.

[0022] In some optional embodiments, the telescopic module 20 is movably provided with a plurality of slides 21, and the pedal module 30 is provided with a movable cavity 32. The telescopic module 20 extends movably into the movable cavity 32, and the slides 21 are installed in the movable cavity 32. The telescopic module 20 and the pedal module 30 are rotatably engaged through the slides 21. An elastic element 31 is disposed in the movable cavity 32 and connected to the slides 21. Through the cooperation of the movable cavity 32 and the slides 21, when the pedal module 30 retracts towards the underside of the office chair seat, the slides 21 can further slide relative to the telescopic module 20 towards the mounting base 10, thereby causing the pedal module 30 to move further towards the mounting base 10. This facilitates the pedal module 30 to retract further under the chair seat, which is equivalent to adding one level of telescopic effect.

[0023] The specific structure of the elastic element 31 can be designed according to actual needs. For example, in this embodiment, the elastic element 31 is a spring, and the two ends of the spring are respectively connected to the inner wall of the slide 21 and the movable cavity 32. The slide 21 is provided with a positioning post for positioning the end of the spring.

[0024] Please see Figures 6 to 8 In some optional embodiments, the slide 21 is provided with a pivot portion 22, and a locking seat 33 is detachably provided in the movable cavity 32. The locking seat 33 presses the pivot portion 22 against the inner wall of the movable cavity 32. The pivot portion 22 is rotatably disposed between the locking seat 33 and the inner wall of the movable cavity 32. The locking seat 33 restricts the pivot portion 22 of the slide 21, thereby facilitating assembly while realizing the rotational engagement of the slide 21 relative to the pedal module 30. The structure is simple. The locking seat 33 can achieve a detachable engagement with the movable cavity 32 through a snap-fit ​​structure, a threaded structure, etc.

[0025] The specific structure of the telescopic module 20 can be designed according to actual needs. For example, in some optional embodiments, the telescopic module 20 includes two telescopic rods 23, which are telescopically engaged with the mounting base 10. Each telescopic rod 23 is provided with a slide block 21, which can slide along the telescopic rod 23. In this embodiment, the mounting base 10 is provided with two mounting holes 11, and the two telescopic rods 23 are correspondingly slidably mounted on the telescopic rods 23. The telescopic rods 23 can be multi-segmented to extend the telescopic distance.

[0026] In some alternative embodiments, a connecting beam 24 connects the two telescopic rods 23. The connecting beam 24 can connect the two telescopic rods 23 into one unit, thereby improving the stability of the pedal module when it moves. The connecting beam 24 is located in the movable cavity 32. When the pedal module moves relative to the mounting base 10 to the unfolded position, the connecting beam 24 moves toward the slide 21 and abuts against the slide 21, which helps to limit the position of the telescopic rods 23 while improving the positional stability of the telescopic rods 23. When the pedal module moves toward the mounting base 10 to the retracted position, the connecting beam 24 moves away from the slide 21.

[0027] In some optional embodiments, a support platform 34 is provided in the movable cavity 32. When the foot pedal module moves toward the mounting base 10 to the retracted position, the support platform 34 is located below the connecting beam 24 and can be used to support the connecting beam 24. This allows the foot pedal module to support the connecting beam 24 through the support platform 34 when it is in the retracted position, thereby limiting the rotation range of the foot pedal module and improving stability when retracted.

[0028] In some alternative embodiments, two limiting parts 35 are provided in the movable cavity 32. When the foot pedal module moves toward the mounting base 10 to the retracted position, the telescopic rod 23 is correspondingly limited and engaged with the limiting parts 35, so that the telescopic rod 23 stops in the accurate position and improves the stability when retracted.

[0029] In some alternative embodiments, the slide 21 is provided with a positioning groove 25. When the foot pedal module moves toward the mounting base 10 to the unfolded position, the connecting beam 24 extends into the positioning groove 25. The positioning groove 25 restricts the position of the connecting beam 24, so that the slide 21 on the two telescopic rods 23 and the connecting beam 24 form a whole. This is beneficial to provide a stable support structure for the rotation of the foot pedal module, so that the foot pedal module can rotate more stably without shaking.

[0030] In some alternative embodiments, the movable cavity 32 is provided with two clearance grooves 36 for avoiding the telescopic rod 23. When the pedal module 30 rotates downward in a direction away from the mounting base 10, the telescopic rod 23 extends into the clearance groove 36, thereby avoiding strong interference between the telescopic rod 23 and the inner wall of the movable cavity 32.

[0031] The aforementioned foot pedal assembly can be applied to an office chair, which includes: the aforementioned foot pedal assembly.
