AI Technical Summary
The folding mechanism of folding scooters is prone to jamming during long-term use and in complex environments, affecting reliability and lifespan.
The combination of a locking mechanism and an elastic component is used. The locking mechanism locks the first and second connecting parts in the unfolded state, and the elastic component automatically compensates for wear gaps to ensure a tight connection.
It effectively resists the impact during riding, prevents accidental folding, extends service life, and improves user experience and overall performance.

Abstract
Claims
1. A folding scooter, characterized in that, include: handlebar; Support frame, connected to the handlebars; Connector; A wheel assembly, including a wheel rotatably mounted on the connecting frame; A folding mechanism is disposed between the support frame and the connecting frame, the folding mechanism comprising: First connecting part; The second connecting part is rotatably connected to the first connecting part. One of the first connecting part and the second connecting part is connected to the support frame, and the other is connected to the connecting frame. The second connecting part rotates relative to the first connecting part so that the support frame and the connecting frame can be folded or unfolded relative to each other. A locking assembly is connected to the second connecting portion. The locking assembly includes a locking mechanism and an elastic portion connected to the locking mechanism. The locking mechanism is used to lock the first connecting portion and the second connecting portion when the support frame and the connecting frame are in the unfolded state, and to press the elastic portion against the first connecting portion to press the first connecting portion toward the second connecting portion.
2. The folding scooter of claim 1, wherein, The locking mechanism further includes: The pressure plate is rotatably connected to the second connecting part; The connecting arm is rotatably connected to the pressure plate; A locking member is disposed on the support frame or the connecting frame, and the locking member is located away from the first connecting portion relative to the second connecting portion; The elastic part is rotatably connected to the end of the connecting arm that is away from the pressure plate; When the locking mechanism locks the first connecting part and the second connecting part, the pressure plate is connected to the locking member.
3. The folding scooter of claim 2, wherein, The locking mechanism further includes: A locking hook is slidably connected to the pressure plate; An elastic element, one end of which is connected to the pressure plate and the other end of which is connected to the locking hook; The locking mechanism is configured such that when the pressure plate rotates toward the locking member, the locking hook abuts against the locking member, the locking hook slides and compresses the elastic member under external force, and when the external force disappears, the locking hook engages with the locking member under the action of the elastic member.
4. The folding scooter of claim 3, wherein, The locking mechanism further includes: The sliding part is connected to the locking hook, and the sliding part is slidably connected to the pressure plate; The sliding part is configured such that when the sliding part is subjected to an external force, it drives the locking hook to move and compresses the elastic member, so that the locking hook disengages from the locking member.
5. The folding scooter of claim 2, wherein, The pressure plate includes: The first pressure plate is rotatably connected to the second connecting part; The second pressure plate is connected to the first pressure plate and is set at an angle. When the locking mechanism locks the first connecting part and the second connecting part, the second pressure plate extends away from the second connecting part.
6. The folding scooter of claim 5, wherein, The pressure plate includes: A preset angle is provided between the plane where the first pressure plate is located and the plane where the second pressure plate is located. The preset angle is greater than 155° and less than 165°.
7. The folding scooter according to claim 2, characterized in that, On a cross section perpendicular to the central axis of the elastic part, the axis of the elastic part is defined as the second point, the connection point between the connecting arm and the pressure plate is defined as the third point, the connection point between the pressure plate and the second connecting part is defined as the fourth point, the distance between the second point and the third point is defined as L1, the distance between the third point and the fourth point is defined as L2, and the ratio of L1 to L2 is (1.2-3.7):
1.
8. The folding scooter of claim 1, wherein, The first connecting part further includes: The slot portion includes a first surface facing away from the second connecting portion, the first surface being recessed into the interior of the slot portion; When the locking mechanism locks the first connecting part and the second connecting part, the elastic part is disposed in the slot part.
9. The folding scooter of claim 8, wherein, A snap-fit component is provided on the side of the slot that is away from the first surface; The folding mechanism further includes: A snap-fit hook is rotatably connected to the second connecting part; A torsion spring abuts against the latching hook. When the locking mechanism locks the first connecting part and the second connecting part, the torsion spring acts on the latching hook to make the latching hook engage with the latching member.
10. The folding scooter of claim 9, wherein, The snap-fit hook includes: A snap-fit part for snapping into the snap-fit component; A limiting part is connected to the snap-fit part, and the limiting part extends in a direction away from the snap-fit part; When the locking mechanism locks the first connecting part and the second connecting part, the locking mechanism abuts against the limiting part to restrict the rotation of the snap hook.
11. The folding scooter of claim 1, wherein, The wheel assembly includes: The front wheel is rotatably connected to the connecting frame; The point where the connecting frame and the support frame are rotatably connected is defined as the first point. The distance from the first point to the central axis of the front wheel is L3. The distance from the first point to the farthest point of the support frame away from the connecting frame is L4. The ratio of L4 to L3 is (1.7-2.5):
1.
12. The foldable scooter of any of claims 1-11, wherein, The elastic part is made of polyurethane.
