[0003] The Chinese invention patent with publication number CN116674686A disclosed on September 1, 2023 that the latch-type folding mechanism and the scooter include a hinged first seat and a second seat to switch between a folded state and an unfolded state; a buckle assembly includes a plug-in portion slidably arranged in the second seat, a matching portion arranged on the first seat, and an elastic member arranged between the plug-in portion and the second seat, the plug-in portion and the matching portion match, and the elastic force of the elastic member drives the plug-in portion to move toward the matching portion. The patent discloses how to prevent the safety hazards of using cam locking.

[0004] The present invention proposes another new technical solution to solve the problem. Summary of the invention

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a folding mechanism and a scooter, which is intended to solve the technical problem in the prior art that the folding part of the scooter is easy to slip and cause safety hazards.

[0006] To achieve the above-mentioned purpose, the utility model proposes a folding mechanism, comprising an upper seat body and a lower seat body hinged to the upper seat body; the upper seat body and the lower seat body are fixed to a fixed state by a cam wrench, the upper seat body is provided with a convex buckle, and the cam wrench is provided with a liftable lock buckle; after the cam wrench fixes the upper seat body and the lower seat body, the lock buckle descends and engages with the convex buckle so that the cam wrench cannot be opened; the lock buckle descends and separates from the convex buckle, and the cam wrench can be opened.

[0007] Preferably, the convex buckle has an upper protrusion extending upward, the lock buckle is provided with a movable block, and the movable block has a lower protrusion extending downward that cooperates with the upper protrusion.

[0008] Preferably, the lock comprises an inverted L-shaped sliding handle, and the cam wrench is provided with a track for the sliding handle to move.

[0009] Preferably, the lower end of the cam wrench is rotatably disposed on a first connecting shaft, and the first connecting shaft is rotatably disposed on the lower seat body.

[0010] Preferably, a second connecting shaft is provided at the upper end of the cam wrench, the second connecting shaft is penetrated and connected with a connecting rod and a third connecting shaft, and the third connecting shaft is rotatably provided on the upper seat body.

[0011] Preferably, one end of the third connecting shaft is connected to the convex buckle, and the other end is connected to a fixing seat, and the fixing seat is parallel to the convex buckle and is arranged on the upper seat body.

[0012] To achieve the above purpose, the utility model also proposes a scooter, which uses the above-mentioned folding mechanism, wherein the lower seat body is a hollow body, and the upper seat body is provided with a vertical rod, and the vertical rod extends downward from the upper seat body; the lower seat body and the upper seat body are in a fixed state, and the vertical rod partially enters the lower seat body.

[0035] The electric scooter has two states, folded state and fixed state. The folded state is for storing the electric scooter to save space. The fixed state is for riding the scooter after unfolding. Embodiment 1

[0036] The utility model provides a scooter that uses a folding mechanism. The folding mechanism needs to be locked when it is in a fixed state, otherwise it is easy to shake and fall off during riding, causing safety hazards. The following specifically introduces a folding mechanism with a locking mechanism.

[0037] See also Figure 1-5 The folding mechanism comprises an upper seat body 1 and a lower seat body 2 hinged to the upper seat body 1. The upper seat body 1 is provided with a vertical rod 6, and a handle is connected above the vertical rod 6 for easy riding, and the lower seat body 2 is connected to a skateboard body for stepping on.

[0038] The upper seat body 1 and the lower seat body 2 are fixed to a fixed state by a cam wrench 3, the upper seat body 1 is provided with a convex buckle 11, and the cam wrench 3 is provided with a liftable lock buckle 4; after the cam wrench 3 fixes the upper seat body 1 and the lower seat body 2, the lock buckle 4 descends and engages with the convex buckle 11 so that the cam wrench 3 cannot be opened; the lock buckle 4 descends and separates from the convex buckle 11, and the cam wrench 3 can be opened.

[0039] by Figure 2 For example, the figure is in a fixed state. When unlocking, you only need to move the lock buckle 4 upward to separate it from the convex buckle 11, then rotate the cam wrench 11 counterclockwise to unlock, and rotate the vertical rod 6 clockwise to fold the upper seat body 1 and the lower seat body 2, and then store them after folding. If it is in a fixed locked state, when the cam wrench 11 is directly pulled, the lock buckle 4 presses the convex buckle 11, and the upper seat body 11 always has a tendency to move downward, and it cannot be unlocked.

[0040] The convex buckle 11 extends upward to form an upper protrusion 111, and the lock buckle 4 is provided with a movable block 41, and the movable block 41 extends downward to form a lower protrusion 411 that cooperates with the upper protrusion 111. The lock buckle 4 includes an inverted L-shaped sliding handle 42, and the cam wrench 3 is provided with a track for the sliding handle 42 to move. The sliding handle 42 is protruding, which is convenient for hand-held control. It is preferred to unlock upwards, and generally pressing down is a habitual action, or pressing down when bumping, so pulling up is set to unlock to prevent accidental touch.

[0041] The lower end of the cam wrench 3 is rotatably arranged on the first connecting shaft 31, and the first connecting shaft 31 is rotatably arranged on the lower seat body 2. The upper end of the cam wrench 3 is provided with a second connecting shaft 32, and the second connecting shaft 32 is connected with a connecting rod 33 and a third connecting shaft 34, and the third connecting shaft 34 is rotatably arranged on the upper seat body 1. When the cam wrench is pulled to unlock, the cam wrench 3 rotates, and the second connecting shaft 32 moves away from the vertical rod 6 along with the cam wrench 3. The third connecting rod 34 rotates on the upper seat body 1. In order to prevent jamming, both the second connecting shaft 32 and the first connecting shaft 31 can rotate.

[0042] One end of the third connecting shaft 34 is connected to the convex buckle 11, and the other end is connected to the fixing seat 5, and the fixing seat 5 is parallel to the convex buckle 11 and is arranged on the upper seat body 1. The complexity of the overall structure can be reduced, and the area can be reduced at the same time. Embodiment 2

[0043] The utility model provides a scooter that uses a folding mechanism. The folding mechanism needs to be locked when it is in a fixed state, otherwise it is easy to shake and fall off during riding, causing safety hazards. Another folding mechanism with a locking mechanism is specifically introduced below.

[0044] See also Figure 6-8 , a folding mechanism comprises an upper seat body 1 and a lower seat body 2 hinged to the upper seat body 1. The lower seat body 2 is a hollow body, and a vertical rod 6 is provided on the upper seat body 1, and the vertical rod 6 extends downward from the upper seat body 1. The lower seat body 2 and the upper seat body 1 are in a fixed state, and the vertical rod 6 partially enters the lower seat body 2. An elastic pin 7 is provided on the lower seat body 2, and a fixing hole 61 is provided on the vertical rod 6; in the fixed state, the elastic pin 7 is inserted into the fixing hole 61 for locking. A spring is provided in the elastic pin 7 so that it always has a tendency to move toward the fixing hole 61, and a pull ring 71 is provided on the side of the elastic pin 7 away from the vertical rod 6. The side of the elastic pin 7 close to the fixing hole 61 is an arc surface, and the bottom of the vertical rod 6 is an arc surface.

[0045] by Figure 6 For example, this state is a fixed state and is locked. When you need to unlock, you only need to pull the pull ring 71 outward. The pull ring has a relatively large area, which is convenient for hand pulling and exerting force. After the elastic pin 7 is away from the fixing hole 61, the vertical rod 6 can be turned clockwise to change to a folded state and then stored. To change to a fixed state, directly turn the vertical rod 6 in the folded state counterclockwise, and the arc surface at the bottom of the vertical rod 6 will first compress the elastic pin 7, and finally make the elastic pin 7 enter the fixing hole 61 for locking. Embodiment 3

[0046] The scooters of Example 1 and Example 2 use only one type of fixed lock for the folding mechanism. Since the scooter is subjected to various forces when in use, a single locking mechanism may often cause safety hazards due to damage or accidental activation. This embodiment uses a folding mechanism that combines the two locking structures of Example 1 and Example 2 on the scooter.

[0047] like Fig. 9 The vertical rod 6 is first fixed with the elastic pin 7, and then after rotating the cam wrench 3, the lock buckle 4 is pulled down for double fixing. The two fixing structures are the same as those in the embodiments 1 and 2, and will not be described here.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
