Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0057] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

[0058] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0059] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0060] like Figures 1-11 As shown, this utility model embodiment provides a footrest, which includes a base 1, at least one support leg 4 connected to the base 1, and a footrest assembly 3. The footrest assembly 3 has a locked state that is fixed relative to the support leg 4, and an unlocked state that is pivotable relative to the support leg 4. When there is one support leg 4, at least one angle adjustment device 2 is provided between the support leg 4 and the foot rest assembly 3 (for example, one angle adjustment device 2 can be provided on one side of one support leg 4, or one angle adjustment device 2 can be provided on both sides of the support leg 4 respectively); when there are multiple support legs 4, each of the multiple support legs 4 is provided with at least one angle adjustment device 2 between itself and the foot rest assembly 3 (for example, one angle adjustment device 2 can be provided on one side of each support leg 4, or one angle adjustment device 2 can be provided on both sides of each support leg 4 respectively), or at least one angle adjustment device 2 is provided between at least one support leg 4 and the foot rest assembly 3 (for example, one angle adjustment device 2 can be provided on one side of one support leg 4, or one angle adjustment device 2 can be provided on both sides of one support leg 4; or one angle adjustment device 2 can be provided on one side or both sides of any one of more than one but not all of the multiple support legs 4).

[0061] Specifically, the angle adjustment device 2 includes a rotating mounting component 22 and a rotating slider 23. The rotating mounting component 22 is provided with an arc-extending track 221 and is connected to the corresponding support leg 4. The rotating slider 23 is slidably connected to the track 221 and is also connected to the foot rest assembly 3. Further, in order to control the foot rest assembly 3 to switch between a locked state and an unlocked state, the foot rest also includes a control component 5. The control component 5 is used to control the locking or unlocking of the rotating slider 23 and the rotating mounting component 22. When the control component 5 controls the rotating slider 23 to unlock from the rotating mounting component 22, the rotating slider 23 can slide within the track 221, thereby driving the foot rest assembly 3 to rotate and adjust, that is, the foot rest assembly 3 is switched to the unlocked state. When the control component 5 controls the rotating slider 23 to lock from the rotating mounting component 22, the rotating slider 23 cannot slide within the track 221, thereby preventing the foot rest assembly 3 from rotating, that is, the foot rest assembly 3 is switched to the locked state.

[0062] The footrest is mounted on a track 221 extending along an arc via a rotating slider 23. When the footrest assembly 3 is unlocked, the slider 23 can slide freely along the track 221 to adjust the angle of the footrest assembly 3. After the angle of the footrest assembly 3 is adjusted, the control component 5 locks the rotating slider 23 and the rotating mounting piece 22 to fix the slider 23, thus switching the footrest assembly 3 to the locked state. This footrest allows for convenient angle adjustment, and the footrest assembly 3 can be suspended and locked, improving the user experience.

[0063] Optionally, such as Figures 3-5 As shown, the rotating mounting component 22 is provided with an arc-shaped groove that opens in the horizontal direction, forming a track 221. At least the bottom of the rotating slider 23 is slidably engaged with the arc-shaped groove. The rotating mounting component 22 provides support to the foot support assembly 3 by rotating the slider 23. The rotating slider 23 slides along the arc-shaped groove to realize the pivoting of the foot support assembly 3 relative to the support leg 4. This structure, by providing an arc-shaped groove in the rotating mounting component 22 to form a track 221, makes the rotating slider 23 easy to assemble and has a simple structure.

[0064] Furthermore, the angle adjustment device 2 also includes a locking block 21. The rotating slider 23 is provided with a receiving cavity 231, and the locking block 21 is movably disposed within the receiving cavity 231 of the rotating slider 23. The locking block 21 can be moved to a position engaged with the rotating mounting member 22 to lock the rotating slider 23 and the rotating mounting member 22. The locking block 21 can also be moved to a position disengaged from the rotating mounting member 22 to unlock the rotating slider 23 and the rotating mounting member 22. The control component 5 includes a control lever, which is configured to drive the locking block 21 to move, thereby locking or unlocking the rotating slider 23 and the rotating mounting member 22.

[0065] Furthermore, the locking block 21 has a plurality of first engaging teeth 211 on the side facing the track 221; the sidewall of the track 221 opposite to the first engaging teeth 211 has a plurality of second engaging teeth 222. When the locking block 21 moves to the point where the first engaging teeth 211 and the second engaging teeth 222 engage, the rotating slider 23 and the rotating mounting member 22 are locked, and the rotating slider 23 cannot slide within the track 221. When the locking block 21 moves to the point where the first engaging teeth 211 and the second engaging teeth 222 disengage, the rotating slider 23 is unlocked from the rotating mounting member 22, and the rotating slider 23 can slide within the track 221. This structure, by providing the first engaging teeth 211 and the second engaging teeth 222, allows the locking block 21 to lock or unlock the rotating slider 23 and the rotating mounting member 22. It is understood that the locking block 21 can only move towards or away from the second engaging teeth 222 within the receiving cavity 231.

[0066] Optionally, such as Figures 6-9 As shown, the locking block 21 is provided with a control groove 212; the control lever is provided with a locking part 511 and an unlocking part 512. When the control lever rotates, it causes the locking part 511 to abut against the upper groove wall of the control groove 212, causing the locking block 21 to move toward the second meshing tooth 222 to a position where it engages with the rotating mounting member 22. Alternatively, when the control lever rotates in the opposite direction, it causes the unlocking part 512 to abut against the lower groove wall of the control groove 212, causing the locking block 21 to move away from the second meshing tooth 222 to a position where it disengages from the rotating mounting member 22. In this structure, by providing an unlocking part 512 and a locking part 511 on the control lever, the control lever can achieve the abutment of the unlocking part 512 with the upper groove wall of the control groove 212 and the abutment of the locking part 511 with the lower groove wall of the control groove 212 when it rotates, thereby realizing the movement of the locking block 21.

[0067] In some embodiments, the unlocking portion 512 and the locking portion 511 are protrusions distributed in a generally V-shape on the outer periphery of the control lever, for example, two protrusions spaced circumferentially with a notch between them. In some embodiments, the unlocking portion 512 and the locking portion 511 are the two circumferential ends of a radially protruding protrusion on the control lever, for example, the two ends of the arcuate portion of an annular protrusion.

[0068] Specifically, the control component 5 includes a control lever 51, a handle 52, and a linkage plate 53. The control lever is located at the end of the control lever 51. The handle 52, the linkage plate 53, and the control lever 51 are rotatably mounted on the foot rest component 3. One end of the linkage plate 53 is connected to the handle 52, and the other end is connected to the control lever 51. When the handle 52 rotates, it drives the control lever 51 to rotate through the linkage plate 53, thereby realizing the rotation of the control lever.

[0069] Optionally, one end of the linkage plate 53 and the control rod 51 are provided with a first elongated hole 531 and a first pin, which is inserted into the first elongated hole 531; the other end of the linkage plate 53 and the handle 52 are provided with a second elongated hole 532 and a second pin, which is inserted into the second elongated hole 532. When the handle 52 is rotated, the first pin can slide along the length direction of the first elongated hole 531, and the second pin can slide along the length direction of the second elongated hole 532, so as to allow relative rotation between the handle 52 and the linkage plate 53, and relative rotation between the linkage plate 53 and the control rod 51. In this embodiment, the first elongated hole 531 and the second elongated hole 532 are respectively provided at both ends of the linkage plate 53, the control rod 51 is provided with a first pin corresponding to the first elongated hole 531, and the handle 52 is provided with a second pin corresponding to the second elongated hole 532.

[0070] Optionally, refer to Figure 2 As shown, the footrest assembly 3 includes a footrest 31 and a connecting plate 32 corresponding to each of the rotating sliders 23. The connecting plate 32 is connected to the corresponding rotating slider 23 and is located at the bottom of the footrest 31. By setting the connecting plate 32 and the footrest 31, the footrest 31 is connected to the rotating slider 23 through the connecting plate 32, so that the footrest 31 can rotate and the user's feet can be placed on the footrest 31.

[0071] The handle 52 can be installed at the center of the side of the footrest assembly 3 facing the user when in use. The user can switch the state of the footrest assembly 3 by stepping on the handle 52, and can easily adjust the tilt angle of the footrest assembly 3 by continuing to apply force in the target direction while stepping on it. It is easy to understand that the track 221 has at least one upward-facing arc-shaped support surface, on which the bottom surface of the rotating slider 23 is supported. Optionally, the bottom surface of the rotating slider 23 and the support surface of the track 221 can be in sliding contact, multi-line contact, multi-point contact, etc. In the unlocked state, when the user steps on the footrest assembly 3 and slightly changes the foot's posture, the footrest assembly 3 is driven to pivot with the user's foot. With the support of the track 221 on the rotating slider 23, even if the user's foot is completely removed from the footrest assembly 3, the footrest assembly 3 will not easily rotate freely without external force, thus temporarily maintaining the target posture, and can then be switched to the locked state. Alternatively, the user can place both feet on the footrest assembly 3 to adjust to the target posture, then keep one foot on the footrest assembly 3 while operating the handle 52 in the control assembly 5 with the other foot. For example, the user's left foot can be placed naturally on the footrest assembly 3 in the target posture (i.e., essentially without exerting force), or even if force is applied, as long as the posture of the left foot is not substantially changed, the user can switch to the locked state by operating the handle 52 in the control assembly 5 with the right foot, locking the footrest assembly 3 in the user's desired posture. Therefore, the user can conveniently adjust the posture of the footrest assembly 3 by operating the foot while the legs are relatively relaxed.

[0072] Furthermore, the footrest assembly 3 also includes a foot pad 33 disposed on the footrest plate 31 to improve user comfort.

[0073] Optionally, such as Figures 10-11 and combined Figure 2 As shown, the footrest also includes a height adjustment device 6, which is used to drive the support leg 4 to rise and fall, so as to adjust the height of the footrest assembly 3.

[0074] Furthermore, the base 1 is provided with sliding holes 11 corresponding to the support legs 4 one by one; the support legs 4 include connecting seats 42 and lifting sliders 41, the lifting sliders 41 are slidably disposed in the corresponding sliding holes 11, the connecting seats 42 are connected to the lifting sliders 41, and the rotating mounting parts 22 are connected to the corresponding connecting seats 42; the height adjustment device 6 is used to drive the lifting sliders 41 to rise and fall, thereby driving the foot rest assembly 3 to rise and fall. By sliding the lifting sliders 41 in the sliding holes 11, the foot rest assembly 3 is driven to rise and fall through the connecting seats 42.

[0075] Furthermore, the support leg 4 also includes a lead screw 43, which is screwed to the corresponding lifting slider 41. The height adjustment device 6 is used to drive the lead screw 43 to rotate, so that the lifting slider 41 can be raised or lowered. By setting the lead screw 43 to be screwed to the lifting slider 41, the lifting slider 41 can be raised or lowered. The structural design is simple and reasonable, and the cost is low.

[0076] To drive the lead screw 43 to rotate, the support leg 4 also includes a first bevel gear 44 connected to the lead screw 43; the height adjustment device 6 includes a transmission rod 61 and a second bevel gear 62 disposed on the transmission rod 61 and meshing with the first bevel gear 44. The transmission rod 61 or the second bevel gear 62 is rotatably connected to the base 1. The transmission rod 61 can drive the second bevel gear 62 to rotate, thereby driving the lead screw 43 to rotate through the first bevel gear 44. The rotation of the transmission rod 61 can drive the second bevel gear 62 to rotate. Since the first bevel gear 44 and the second bevel gear 62 mesh with each other, the second bevel gear 62 can be driven to rotate, thereby driving the lead screw 43 to rotate.

[0077] It is understood that the helix angle of the lead screw 43 is set in the range of less than 45°, and in this embodiment it is preferably between 20° and 30°, so that the lead screw 43 can achieve self-locking, that is, the lead screw 43 can only be rotated by rotating the transmission rod 61, and under the limited force, the lead screw 43 cannot drive the transmission rod 61 to rotate.

[0078] Furthermore, the height adjustment device 6 also includes a knob 63 and a third bevel gear 64 connected to the knob 63. The third bevel gear 64 meshes with any one of the second bevel gears 62. In this structure, the user can rotate the knob 63 to drive the third bevel gear 64 to rotate, which in turn drives the transmission rod 61 to rotate via the second bevel gear 62, making operation more convenient.

[0079] In this embodiment, the foot rest has two support legs 4 connected to the base 1. The base 1 has two spaced sliding holes 11, and the two support legs 4 are slidably disposed within the two sliding holes 11. Each support leg 4 is equipped with an angle adjustment device 2. The two connecting plates 32 of the foot rest assembly 3 are connected to the rotating sliders 23 of the angle adjustment devices 2 on the corresponding two support legs 4. The transmission rod 61 is equipped with two second bevel gears 62. The two lifting sliders 41 are each equipped with a lead screw 43, and each lead screw 43 is equipped with a first bevel gear 44. The two first bevel gears 44 mesh with the second bevel gears 62, and the third bevel gear 64 meshes with one of the two second bevel gears 62, so as to simultaneously drive the two lifting sliders 41 to rise and fall. By setting two support legs 4, the foot rest makes the distribution of structural components more reasonable.
