In the related art, a foldable scooter is generally provided with a folding mechanism between a support frame and a frame, and the folding mechanism is used for folding and storing. However, the conventional folding mechanism can be reliably locked in the use process of the support frame and the frame, but after the locking piece is released, the support frame and the frame are in a separable state, and if the ground is uneven or an operator does not operate properly, the support frame can be folded to smash people or objects, so that potential safety hazards are caused.

Based on this, this application provides a folding mechanism, can not take place to empty easily after the unblock locking, can improve the security performance of automobile body device and collapsible car of riding instead of walk.

For a better understanding of the folding mechanism of the present disclosure, reference is made to a foldable walker to which the folding mechanism is applied.

As shown in fig. 1 to 5, in some embodiments of the present disclosure, a foldable scooter 10 is provided, which includes a body device 11 and a wheel assembly 12, wherein the body device 11 includes a frame 11a, a support frame 11b and a folding mechanism 11c, and the wheel assembly 12 includes at least two wheels 12a rotatably mounted on the frame 11 a.

The folding mechanism 11c includes a connecting assembly 100, a locking assembly 200, an elastic assembly 300, a control assembly 400 and a locking assembly 500. The connecting assembly 100 includes a first connecting member 110 fixedly connected to the frame 11a and a second connecting member 120 fixedly connected to the supporting frame 11b, and the second connecting member 120 is rotatably connected to the first connecting member 110 and has a use state and a folded state. The locking assembly 200 includes a locking member 210 movably disposed at the coupling assembly 100, the locking member 210 having a locked state locking the second coupling member 120 in the use state and an unlocked state unlocking the second coupling member 120. The elastic assembly 300 includes a first elastic member 310, and the first elastic member 310 serves to elastically lock the locking member 210 in the locked state. The control assembly 400 includes a control member 410, the control member 410 is movably disposed on the connecting assembly 100 and is in transmission connection with the locking member 210, and the control member 410 has a first control state for controlling the locking member 210 to be fixed in the locking state and a second control state capable of driving the locking member 210 to be switched to the unlocking state. The locking assembly 500 is used to lock the control member 410 in the first control state or to release the control member 410.

When the foldable scooter 10 needs to be used, the supporting frame 11b is fixedly arranged above the frame 11a, the locking member 210 locks the first connecting member 110 and the second connecting member 120 in the use state through the first elastic member 310, and the control member 410 is fixed in the first control state through the locking assembly 500, so that the control member 410 controls the locking member 210 to be fixed in the locking state, further the first connecting member 110 and the second connecting member 120 are reliably connected in the use state, the supporting frame 11b and the frame 11a are also reliably connected, the foldable scooter cannot be folded, and the safety is high. Thus, the vehicle body frame 11a is moved by the rolling of the wheels 12a, carrying the driver. That is, in the using process of the foldable scooter 10, the control assembly 400 is used to realize rigid locking of the locking member 210 and elastic locking of the elastic assembly 300, so that the support frame 11b and the frame 111a are reliably connected and have high safety.

As shown in fig. 8, when the foldable scooter 10 needs to be folded for storage or transportation, the locking assembly 500 releases the control member 410, so that the control member 410 drives the locking member 210 to overcome the locking force of the first elastic member 310 and switch to the unlocking state, and the locking member 210 releases the first connecting member 110 and the second connecting member 120, so that the second connecting member 120 can be folded relative to the first connecting member 110, and the supporting frame 11b can be folded onto the frame 11a, so that the supporting frame 11b and the frame 11a are folded for storage, transportation and the like. When the locking assembly 500 releases the control member 410, so that the control member 410 is separated from the first control state and the locking member 210 is not in the unlocking state, even if an improper operation or an accidental operation occurs, the locking member 210 is elastically locked in the locking state by the first elastic member 310, so that the support frame 11b is not easily folded. That is, the locking member 210 can be released from the locking state and the supporting frame 11b can be folded by overcoming the locking force of the first elastic member 310 elastically locking the locking member 210.
