Description

TECHNICAL FIELD

[0001] The application relates to a footrest unlocking mechanism, in particular to a one-side unlocking mechanism for a seat or other equipment requiring quick adjustment of the footrest position. BACKGROUND

[0002] In the prior art, unlocking and adjustment of the footrest usually require complex operations or the coordinated action of multiple components, which not only increases the complexity and cost of the equipment, but also reduces the user experience. In addition, the existing footrest adjustment mechanism may have problems such as inconvenient operation and unstable structure during unlocking and rotation adjustment. Therefore, a simple, convenient and reliable footrest unlocking mechanism is needed to meet the demand for quick adjustment of the footrest position. SUMMARY

[0003] The application aims to provide a one-side unlocking mechanism for a footrest, which is novel and simple in structure and can achieve unlocking and rotation adjustment of the footrest through simple one-side operation while ensuring the stability and reliability of the structure.

[0004] The technical solution of the application is a one-side unlocking mechanism for a footrest, which comprises an equipment body and a footrest. The footrest is rotatably connected to the equipment body through connecting seats on both sides. Locking members are arranged between the connecting seats and the mounting seats on both sides to lock the connecting seats and the mounting seats and to unlock them through unlocking movement. The locking members on both sides are connected through a linkage member. One side of the equipment body or the footrest has an unlocking member that can drive the corresponding locking member to perform unlocking movement. When the unlocking member drives the corresponding locking member on one side to perform unlocking movement, the unlocking movement is transmitted to the locking member on the other side through the linkage member to make it perform unlocking movement at the same time, thereby achieving synchronous unlocking on both sides. After unlocking, the footrest can be adjusted in rotation relative to the equipment body.

[0005] As a preferred technical solution, the locking member is a multi-position locking member that can lock the connecting seat and the mounting seat when the footrest is at different angular positions relative to the equipment body.

[0006] As a preferred technical solution, the unlocking movement of the locking member is a transverse movement.

[0007] As a preferred technical solution, the connecting seats on both sides of the footrest are installed on the outside of the mounting seats on both sides of the equipment body. The unlocking movement of the locking members on both sides is a same-direction movement. When unlocking, the locking member on one side is retracted into the corresponding mounting seat and exits the corresponding connecting seat, and the locking member on the other side is retracted into the corresponding connecting seat and exits the corresponding mounting seat.

[0008] As a preferred technical solution, the linkage member is a traction cable or a linkage rod.

[0009] As a preferred technical scheme, the unlocking part is an unlocking button, which can directly push the locking part on the corresponding side; the unlocking button is provided with a reset part between the device body or the foot.

[0010] Compared with the prior art, the application has the following advantages:

[0011] 1. The application adopts a single-side unlocking mode to simultaneously release the locking of both sides of the foot and the device body, so that the unlocking and rotation adjustment of the foot can be realized through simple operation, the user does not need a complex operation process, the use convenience is greatly improved, and the stability and reliability of the structure are ensured.

[0012] 2. The application has fewer overall components, compact structure, small space occupation, and convenient maintenance, and has high market competitiveness and application value. BRIEF DESCRIPTION OF DRAWINGS

[0030] like Figures 1 to 4 As shown, a single-sided unlocking mechanism for a foot pedal includes a device body 1 and a foot pedal 2. The two sides of the foot pedal 2 are rotatably connected to the mounting seats 101 on both sides of the device body 1 via connecting seats 201. A locking element 3 is provided between the connecting seat 201 and the mounting seat 101 on each side, which can lock the two and unlock them through an unlocking movement. The two locking elements 3 are connected by a linkage 4. One side of the device body 1 or the foot pedal 2 has an unlocking element 5 that can drive the corresponding locking element 3 to perform an unlocking movement.

[0031] When the foot pedal 2 is locked to the device body 1, the locking pieces 3 on both sides are locked in the corresponding connecting seat 201 and mounting seat 101. At this time, the foot pedal 2 cannot rotate relative to the device body 1.

[0032] When foot pedal 2 needs to be unlocked, the unlocking component 5 is operated. The unlocking component 5 drives the locking component 3 on the corresponding side to perform an unlocking movement, and transmits the movement to the locking component 3 on the other side through the linkage component 4, so that it can perform an unlocking movement at the same time. This achieves synchronous unlocking of the connecting seats 201 on both sides and the mounting seat 101. After unlocking, foot pedal 2 can be rotated and adjusted relative to the device body 1.

[0033] In this embodiment, the locking member 3 is a multi-position locking member, which can lock the connecting seat 201 and the mounting seat 101 when the foot 2 is in different angular positions relative to the device body 1. Figure 4 The example illustrates a common multi-position locking component, which is a gear. The connecting seat 201 and the mounting seat 101 each have corresponding tooth grooves. This design facilitates multi-position adjustment and multi-position locking of the pedal 2.

[0034] In this embodiment, the rotation axis between the connecting seat 201 and the mounting seat 101 is arranged laterally, so that the foot 2 can be flipped up and down to adjust the angle. The unlocking movement of the locking member 3 is a lateral movement.

[0035] In the embodiment, the linkage 4 can be a traction cable or a linkage rod, and the linkage rod is preferred in the figure, the two ends of which are fixedly connected with the locking members 3 on the two sides respectively, so as to ensure the stability and reliability of the unlocking process and avoid unlocking failure caused by loose or failure of the components.

[0036] In the embodiment, a specific mounting mode of the footstep and the equipment body is listed: the connecting seats 201 on the two sides of the footstep 2 are mounted outside the mounting seats 101 on the two sides of the equipment body 1, the locking members 3 on the two sides are linked through the linkage rod and the unlocking movement is a same direction movement; when unlocking, the locking member 3a on one side is retracted into the corresponding mounting seat 101a and exits the corresponding connecting seat 201a, and the locking member 3b on the other side is retracted into the corresponding connecting seat 201b and exits the corresponding mounting seat 101b.

[0037] In the embodiment, the unlocking member 5 is preferably an unlocking button, and a reset member (not shown in the figure) is arranged between the unlocking button and the equipment body 1 or the footstep 2. In the embodiment, the unlocking button is arranged at the outer end of the connecting seat 201a on one side of the footstep 2, the inner side of the unlocking button extends into the connecting seat 201a through the linkage rib and abuts against the corresponding locking member 3a, and when the unlocking button is pressed, it can directly push the locking member 3a on the corresponding side, and under the linkage action of the linkage member 4, it is conducted to the locking member 3b on the other side, so that the locking members 3a and 3b on the two sides simultaneously perform the unlocking movement, and the connecting seats 201 and the mounting seats 101 on the two sides are simultaneously unlocked.

[0038] The application is suitable for a seat, a vehicle (such as a child stroller) footstep or other equipment that needs to quickly adjust the position of the footstep. In the embodiment, the equipment body 1 is a child seat body.

[0039] The application adopts a single-side unlocking mode to simultaneously release the locking of the footstep 2 and the equipment body 1 on the two sides, and through simple single-side operation, the unlocking and rotational adjustment of the footstep 2 can be realized, the user does not need a complex operation process, the convenience of use is greatly improved, and the stability and reliability of the structure are ensured. In addition, the application has fewer overall components, compact structure, small space occupation, and convenient maintenance, and has high market competitiveness and application value.
