[0078] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0079] Reference below Figure 1-Figure 32 The footrest 100 according to the first embodiment of the present invention is described below.

[0080] like Figures 1-6 As shown, the footrest 100 according to the embodiment of the first aspect of the present invention includes: a support rod 1, a connecting member 2 and a footrest body 3.

[0081] The connecting member 2 has a first end 21 and a second end 22, and the connecting member 2 is rotatably connected to the support rod 1 through the first end 21 so as to be rotatable relative to the support rod 1 between an open position and a folded position; the footrest body 3 is rotatably connected to the second end 22, wherein, in the folded position, the connecting member 2 and the footrest body 3 are folded on the lower side of the support rod 1, and in the open position, the connecting member 2 drives the footrest body 3 to extend out of the support rod 1 for stepping.

[0082] For example Figure 1 and Figure 2 As shown, the first end 21 of the connecting member 2 is rotatably connected to the front end of the support rod 1. In a specific example, for example Figure 5 and Figure 6 As shown, the footrest body 3 includes an upper body 31 and a lower body 32, and the upper body 31 and the lower body 32 are connected together by bolts. Figure 5 As shown, the connector 2 is in the open position, e.g. Figure 6 As shown, the connector 2 is in the retracted position. The connector 2 can rotate between the open position and the retracted position about the connection between the first end 21 and the front end of the support rod 1. In one specific example, the support rod 1 is made of carbon steel, the connector 2 is made of aluminum alloy, and the footrest body 3 is made of plastic.

[0083] In this embodiment, when the footrest 100 is not in use, the connector 2 can be rotated to the stowed position, for example Figure 6 As shown, at this time, the connecting member 2 and the footrest body 3 are folded together and are both located on the lower side of the support rod 1, so that the footrest 100 can be effectively stored, thereby effectively saving space.

[0084] When the footrest 100 is needed, the connector 2 can be rotated to the open position, for example Figure 5 As shown, the rotation of the connector 2 can drive the footrest body 3 to rotate, thereby allowing the footrest body 3 to extend out of the support rod 1 for easier stepping. When the connector 2 is in the open position, the footrest body 3 can be adjusted as needed, so that the footrest body 3 can be rotated around the second end 22 to a suitable position, thereby effectively meeting different usage requirements.

[0085] According to the footrest 100 of the embodiment of the present invention, a support rod 1, a connector 2 and a footrest body 3 are provided in the footrest 100, the connector 2 having a first end 21 and a second end 22, the connector 2 is rotatably connected to the support rod 1 through the first end 21, so as to be rotatable relative to the support rod 1 between an open position and a retracted position, and the footrest body 3 is rotatably connected to the second end 22, wherein, in the retracted position, the connector 2 and the footrest body 3 are folded on the lower side of the support rod 1, and in the open position, the connector 2 drives the footrest body 3 to extend out of the support rod 1 for stepping, so that the footrest 100 can not only effectively unfold and retract the footrest body 3, but also can effectively adjust the footrest body 3 when the footrest body 3 is unfolded, thereby effectively meeting the different usage needs of users, and thereby effectively improving the user's usage experience.

[0086] In one embodiment of the present invention, Figure 2-13 As shown, the footrest 100 also includes: a first locking mechanism 4, the first locking mechanism 4 includes a first locking member 41 and a second locking member 42, the first locking member 41 is fixed to the first end 21, and the second locking member 42 is connected to the support rod 1, the first locking mechanism 4 has a first locking state and a first unlocking state, in the first locking state, the first locking member 41 and the second locking member 42 are locked and matched to make the connecting member 2 relatively fixed to the support rod 1, in the first unlocking state, the first locking member 41 and the second locking member 42 can move relative to each other, so that the connecting member 2 can rotate relative to the support rod 1.

[0087] For example Figure 2 As shown, the number of the first locking members 41 can be two, and the two first locking members 41 are respectively arranged on the left and right sides of the first end 21 and fixedly connected to the first end 21, that is, when the connecting member 2 rotates relative to the support rod 1, the first locking member 41 can rotate with the connecting member 2.

[0088] There can be two second locking members 42, one on each side of the support rod 1 and fixedly connected to the support rod 1. That is, when the connecting member 2 rotates relative to the support rod 1, the second locking members 42 do not rotate, and the second locking members 42 can cooperate with the first locking member 41 to achieve locking or unlocking. In one specific example, the first locking member 41 is made of aluminum alloy, and the second locking member 42 is also made of aluminum alloy.

[0089] When the first locking mechanism 4 is in the first locking state, the first locking member 41 and the second locking member 42 cooperate to achieve a locking function, thereby preventing the connecting member 2 from rotating relative to the support rod 1, thereby effectively fixing the position of the footrest body 3 and providing stable support for the user. When the first locking mechanism 4 is in the first unlocking state, the locking cooperation between the first locking member 41 and the second locking member 42 is released. At this time, the user can rotate the connecting member 2 to effectively expand or retract the footrest body 3.

[0090] This embodiment provides a first locking mechanism 4 in the footrest 100, and provides a first locking member 41 and a second locking member 42 in the first locking mechanism 4. The first locking member 41 is fixed to the first end 21, and the second locking member 42 is connected to the support rod 1. The first locking mechanism 4 has a first locking state and a first unlocking state. In the first locking state, the first locking member 41 and the second locking member 42 are locked and matched to fix the connecting member 2 to the support rod 1 relatively. In the first unlocking state, the first locking member 41 and the second locking member 42 are disengaged, and the connecting member 2 is rotatable relative to the support rod 1. Not only can the first locking mechanism 4 effectively fix the footrest body 3 in the first locking state, thereby providing stable support for the user, but the first locking mechanism 4 can also effectively unfold or retract the footrest body 3 in the first unlocking state, thereby meeting the different needs of users.

[0091] In one embodiment of the present invention, Figures 8-16 As shown, the first locking mechanism 4 further includes: a first pushing member 43 and a first elastic member 44 .

[0092] The first pushing member 43 is movable between a first position and a second position, and the first pushing member 43 is configured to push the second locking member 42 to lock with the first locking member 41 when moving from the first position to the second position; the first elastic member 44 is connected between the second locking member 42 and the first pushing member 43, and the first elastic member 44 is used to always push the first pushing member 43 to move to the first position.

[0093] For example Figure 9 As shown, the first pusher 43 is in the first position. Figure 8As shown, the first pusher 43 is in the second position. When the first pusher 43 moves from the first position to the second position, the second locking member 42 on the right side of the support rod 1 can be locked and matched with the first locking member 41, so that the connecting member 2 and the support rod 1 are relatively fixed. The first locking mechanism 4 also includes a second pusher 45. When the first pusher 43 moves from the first position to the second position, the second pusher 45 can move from the seventh position to the eighth position. At this time, the second pusher 45 can make the second locking member 42 on the left side of the support rod 1 locked and matched with the first locking member 41, so that the connecting member 2 and the support rod 1 are relatively fixed. In a specific example, the material of the first pusher 43 is carbon steel, and the material of the second pusher 45 is carbon steel.

[0094] In this embodiment, a first pushing member 43 is provided in the first locking mechanism 4, and the first pushing member 43 is movable between a first position and a second position. The first pushing member 43 is configured to push the second locking member 42 to lock with the first locking member 41 when moving from the first position to the second position, so that the first pushing member 43 can effectively abut against the left side of the first locking member 41, thereby effectively realizing the locking effect.

[0095] In a specific example, for example Figure 8 and Figure 9 As shown, the first elastic member 44 is a coil spring made of carbon steel. There may be two first elastic members 44, each disposed on either side of the support rod 1. Specifically, one end of the first elastic member 44 on the right side of the support rod 1 abuts the first pusher 43, and the other end abuts the second locking member 42 on the right side of the support rod 1. The first elastic member 44 on the left side of the support rod 1 abuts the second pusher 45 at one end, and the other end abuts the first locking member 41 on the left side of the support rod 1 at the other end.

[0096] In this embodiment, a first elastic member 44 is provided in the first locking mechanism 4. The first elastic member 44 is connected between the second locking member 42 and the first pushing member 43. The first elastic member 44 is used to always push the first pushing member 43 to the first position, so that the first elastic member 44 is always in a stressed state, so that the first elastic member 44 is always in contact with the second locking member 42, thereby effectively improving the stability of the connection member 2 in rotation relative to the support rod 1.

[0097] In one embodiment of the present invention, Figure 17 and Figure 18 As shown, the footrest 100 further includes: a connecting shaft 5 and a driving handle 6.

[0098] The connecting axis 5 is along a first direction (eg Figure 17The first locking member 41, the second locking member 42, the first pushing member 43, and the first elastic member 44 are all mounted on the connecting shaft 5, and the first pushing member 43 is fixed to the connecting shaft 5. The driving handle 6 is connected to the connecting shaft 5 and is used to drive the first pushing member 43 between the first position and the second position via the connecting shaft 5. It should be noted that in a specific example, the first direction is the left-right direction.

[0099] In a specific example, for example Figure 17 As shown, the connecting shaft 5 is made of carbon steel, and the connecting shaft 5 is extended left and right. Three bolt holes are provided on the connecting shaft 5, namely the first bolt hole 51, the second bolt hole 52 and the third bolt hole, wherein the third bolt hole is provided at the left end of the connecting shaft 5 and extends in the left and right directions.

[0100] The first pusher 43 is provided with a bolt hole, and the connecting shaft 5 and the first pusher 43 are fixedly connected by a key connection and a bolt connection. The driving handle 6 is provided with a bolt hole, and the connecting shaft 5 and the driving handle 6 are fixedly connected by a key connection and a bolt connection. In addition, the second pusher 45 is provided with a bolt hole, and the connecting shaft 5 and the second pusher 45 are fixedly connected by a key connection and a bolt connection. In one specific example, the driving handle 6 is made of plastic.

[0101] When the driving handle 6 is rotated, the driving handle 6 drives the connecting shaft 5 to rotate, and the connecting shaft 5 drives the first pusher 43 to rotate and move between the first position and the second position. At the same time, the connecting shaft 5 drives the second pusher 45 to rotate and move between the seventh position and the eighth position. When the driving handle 6 is rotated, due to the fixed connection between the driving handle 6 and the connecting shaft 5, the fixed connection between the connecting shaft 5 and the first driving member, and the fixed connection between the connecting shaft 5 and the second driving member, the connecting shaft 5 and the driving handle 6 can also rotate and move in the left-right direction.

[0102] In this embodiment, a connecting shaft 5 is provided in the footrest 100, and the connecting shaft 5 extends along the first direction. The first locking member 41, the second locking member 42, the first pushing member 43 and the first elastic member 44 are all mounted on the connecting shaft 5. The first pushing member 43 is fixed to the connecting shaft 5, so that when the connecting shaft 5 rotates, it can effectively drive the first pushing member 43 to rotate and move between the first position and the second position, thereby effectively realizing the switching of the first locking mechanism 4 between the first locking state and the first unlocking state; by providing a driving handle 6 in the footrest 100, the driving handle 6 is connected to the connecting shaft 5, and is used to drive the first pushing member 43 to move between the first position and the second position through the connecting shaft 5, which can effectively simplify the process of rotating the connecting shaft 5, thereby effectively improving the user's experience.

[0103] In one embodiment of the present invention, Figures 8-13As shown, the first locking member 41 is provided with a first tooth portion 411, and the second locking member 42 is provided with a second tooth portion 421. In the first locked state, the first tooth portion 411 and the second tooth portion 421 are meshed, so that the first locking member 41 and the second locking member 42 are relatively fixed in the circumferential direction of the connecting shaft 5. For example, when the first locking mechanism 4 is in the first unlocked state, the first tooth portion 411 and the second tooth portion 421 are meshed and can rotate relative to each other. For another example, when the first locking mechanism 4 is in the first unlocked state, the first tooth portion 411 and the second tooth portion 421 are separated in the axial direction of the connecting shaft 5 and can rotate relative to each other.

[0104] In a specific example, when the first locking mechanism 4 is in the first locking state, the right end of the first pusher 43 abuts against the left end of the second locking member 42 on the right side of the support rod 1, and the first tooth portion 411 on the right side of the support rod 1 meshes with the second tooth portion 421, thereby fixing the first locking member 41 and the second locking member 42 on the right side of the support rod 1 relative to each other in the circumferential direction of the connecting shaft 5. At the same time, the right end of the second pusher 45 abuts against the left end of the first locking member 41 on the left side of the support rod 1, and the first tooth portion 411 on the left side of the support rod 1 meshes with the second tooth portion 421, thereby fixing the first locking member 41 and the second locking member 42 on the left side of the support rod 1 relative to each other in the circumferential direction of the connecting shaft 5. In this way, the connecting member 2 and the support rod 1 can be relatively fixed.

[0105] When the first locking mechanism 4 is in the first unlocked state, the right end of the first pusher 43 is separated from the left end of the second locking member 42 on the right side of the support rod 1, and a first elastic member 44 is provided between the two. The first tooth portion 411 on the right side of the support rod 1 is engaged with the second tooth portion 421. Under the action of the elastic member, the first locking member 41 and the second locking member 42 on the right side of the support rod 1 can rotate relative to each other. At the same time, the right end of the second pusher 45 is separated from the left end of the first locking member 41 on the left side of the support rod 1, and a first elastic member 44 is provided between the two. The first tooth portion 411 on the left side of the support rod 1 is engaged with the second tooth portion 421. Under the action of the elastic member, the first locking member 41 and the second locking member 42 on the left side of the support rod 1 can rotate relative to each other. In this way, the connecting member 2 and the support rod 1 can rotate relative to each other.

[0106] In this embodiment, a first tooth portion 411 is provided on the first locking member 41 and a second tooth portion 421 is provided on the second locking member 42. In the first locking state, the first tooth portion 411 is meshed with the second tooth portion 421, so that the first locking member 41 and the second locking member 42 are relatively fixed in the circumferential direction of the connecting shaft 5. In the first unlocking state, the first tooth portion 411 and the second tooth portion 421 are separated in the axial direction of the connecting shaft 5, which can effectively simplify the structure of the first locking member 41 and the second locking member 42 and effectively ensure the reliability of the connection between the first locking member 41 and the second locking member 42.

[0107] In one embodiment of the present invention, Figure 10-13 As shown, the first locking member 41 is provided with a first limiting portion 412 extending toward the second locking member 42, and a raised second limiting portion 422 is formed on the inner wall of the second locking member 42. When the connecting member 2 is in the open position, the first limiting portion 412 and the second limiting portion 422 abut on one side of the circumference of the connecting shaft 5. When the connecting member 2 is in the retracted position, the first limiting portion 412 and the second limiting portion 422 abut on the other side of the circumference of the connecting shaft 5. In a specific example, by providing the first limiting portion 412 and the second limiting portion 422, the rotation angle range of the connecting member 2 relative to the support rod 1 is 0° to 195°.

[0108] In this embodiment, a first limiting portion 412 extending toward the second locking portion 42 is provided on the first locking member 41, and a protruding second limiting portion 422 is formed on the inner wall of the second locking member 42. When the connecting member 2 is in the open position, the first limiting portion 412 and the second limiting portion 422 abut on one side of the circumference of the connecting shaft 5. When the connecting member 2 is in the retracted position, the first limiting portion 412 and the second limiting portion 422 abut on the other side of the circumference of the connecting shaft 5. This can limit the rotation angle of the connecting member 2 relative to the support rod 1 to a predetermined range, thereby preventing the rotation angle from exceeding the predetermined range, thereby effectively improving the overall stability and reliability of the footrest 100.

[0109] In one embodiment of the present invention, Figure 19 and Figure 20 As shown, the footrest 100 also includes: a mounting seat 7, the support rod 1 is rotatably connected to the first end 21 through the mounting seat 7, the mounting seat 7 is formed with a mounting groove, the connecting shaft 5 is rotatably passed through the mounting seat 7, and the first locking mechanism 4 is arranged in the mounting groove.

In the direction from one end of the circumference of the connecting shaft 5 toward the other end, the first inclined surface 7111 extends obliquely toward one side of the axial direction of the connecting shaft 5. When the driving handle 6 drives the first push member 43 to rotate from the first position to the second position through the connecting shaft 5, the first push member 43 abuts against the first inclined surface 7111 and slides along the first inclined surface 7111.

[0113] In a specific example, the number of protrusions 711 is three. When the driving handle 6 drives the first push member 43 to rotate from the first position to the second position through the connecting shaft 5, the left end of the first push member 43 abuts against the first inclined surface 7111 and slides along the first inclined surface 7111, thereby rotating the first push member 43 and moving to the right along the axial direction of the connecting shaft 5.

[0114] In this embodiment, a protrusion 711 is provided on the inner wall of the mounting groove, which protrudes axially along the connecting shaft 5. A first inclined surface 7111 is formed on the protrusion 711, which extends circumferentially along the connecting shaft 5. In the direction from one end of the circumference of the connecting shaft 5 toward the other end, the first inclined surface 7111 extends obliquely toward one side of the axial direction of the connecting shaft 5, which can guide the first pushing member 43. The first pushing member 43 is driven by the driving handle 6 to abut against the first inclined surface 7111 and slide along the first inclined surface 7111, which can effectively improve the stability of the first pushing member 43 during the movement.

Furthermore, the mounting slot on the right side of the mounting base 7 is keyed to the second locking member 42 on the right side of the mounting base 7. The second locking member 42 on the left side of the mounting base 7 is located in the mounting slot on the left side of the mounting base 7. Parts of the first elastic member 44 and the first locking member 41 on the left side of the mounting base 7 are located in the mounting slot on the left side of the mounting base 7. Furthermore, the mounting slot on the left side of the mounting base 7 is keyed to the second locking member 42 on the left side of the mounting base 7.

[0117] In this embodiment, mounting grooves are provided at both ends of the mounting seat 7 in the first direction. There are two first locking mechanisms 4, which correspond one to one with the mounting grooves. At least a portion of any first locking mechanism 4 is provided in the corresponding mounting groove, which can make the force on the mounting seat 7 more uniform and effectively optimize the layout of the first locking mechanism 4, thereby effectively improving the reliability of the force and effectively reducing deformation or wear caused by uneven force.
