[0023] This application discloses a folding device, including a fixed tube 100 and a folding tube 200 hinged to each other; a locking assembly 300 and a lever component 400 are provided on the fixed tube 100, and the locking assembly 300 and the lever component 400 can lock the fixed tube 100 and the folding tube 200 independently; the lever component 400 is rotatably disposed on the fixed tube 100 and has a pushing end 411, and the lever component 400 has a first rotation position and a second rotation position. In the first rotation position, the lever component 400 locks the fixed tube 100 and the folding tube 200; in the second rotation position, the lever component 400 unlocks the fixed tube 100 and the folding tube 200, and drives the locking assembly 300 to unlock the fixed tube 100 and the folding tube 200.

[0024] In this embodiment, the fixed tube 100 and the folding tube 200 are hinged together. For example, the fixed tube 100 is connected to the vehicle body and is immovable; the folding tube 200 is connected to the handlebars and can be rotated and folded when needed; the fixed tube 100 is provided with a locking assembly 300 and a lever component 400, which can independently lock the fixed tube 100 and the folding tube 200; that is, the fixed tube 100 and the folding tube 200 are doubly locked; the lever component 400 is rotatably mounted on the fixed tube 100 and has a pushing end 411. The lever component 400 has multiple rotational positions when rotating, including at least a first rotational position and a second rotational position. In the first rotational position, the latch component 400 locks the fixed tube 100 and the folding tube 200; in the second rotational position, the latch component 400 unlocks the fixed tube 100 and the folding tube 200, and drives the locking assembly 300 to unlock the fixed tube 100 and the folding tube 200; that is, when the latch component 400 is in the second position, the folding tube 200 can be rotated and folded; in this way, by doubly locking the fixed tube 100 and the folding tube 200, the connection reliability between the two can be improved, and the problem of false locking can be reduced to a certain extent; at the same time, the rotation of the latch component 400 can drive the unlocking of the locking assembly 300, which does not require separate operation and greatly improves the convenience of the unlocking process.

[0025] In an optional or preferred embodiment, the latch component 400 further has a third rotational position. In the third rotational position, the latch component 400 unlocks the fixing tube 100 and the folding tube 200, and the locking assembly 300 locks the fixing tube 100 and the folding tube 200. With this design, when the latch component 400 is not pushed to the preset position to properly lock the fixing tube 100 and the folding tube 200, the locking assembly 300 achieves a locking effect on the fixing tube 100 and the folding tube 200, preventing the folding tube 200 from mis-locking. The third rotational position can be between the first rotational position and the second position. Optionally, there can be multiple rotational positions with the above-mentioned functions between the first rotational position and the second position.

[0026] In an optional or preferred embodiment, the locking assembly 300 includes a hook 310 that is elastically reset and rotatably disposed on the fixed tube 100; the hook 310 locks the fixed tube 100 and the folding tube 200 when not subjected to external force; the hook 310 is provided with a push end 311 corresponding to the push end 411 so that the connection between the fixed tube 100 and the folding tube 200 can be unlocked when the push end 311 is pushed by the push end 411.

[0027] In this embodiment, the hook 310, which can be elastically reset and rotated on the fixed tube 100, locks the fixed tube 100 and the folding tube 200 when there is no external force, so that the folding tube 200 cannot be rotated and folded; when the push end 411 of the buckle component 400 pushes the push end 311 on the hook 310, the hook 310 rotates to unlock the connection between the fixed tube 100 and the folding tube 200.

[0028] In an optional or preferred embodiment, the hook member 310 includes a first hook end 312, a hook rotation center, and a push end 311 arranged sequentially from top to bottom in the vertical direction; the first hook end 312 can hook and lock the folding tube 200; through the lever structure design of the hook member 310, when the push end 311 is pushed by force, the first hook end 312 rotates to unlock the folding tube 200.

[0029] In an optional or preferred embodiment, a groove 110 is provided on the fixed tube 100 corresponding to the pushed end 311, extending radially along the fixed tube 100. A spring (not shown) is provided in the groove 110 to be connected to the pushed end 311. When the pushed end 311 is subjected to a pushing force toward the fixed tube 100, the spring is compressed. When the pushed end 311 is not subjected to force, the spring returns to its original position to stably lock the folded tube 200.

[0030] In an optional or preferred embodiment, the fixed tube 100 may not have the groove 110 and spring, but instead directly uses the torsion spring to hinge the hook 310, thereby giving it a tendency to elastically rotate and reset.

[0031] In an optional or preferred embodiment, a first hook groove 210 is provided on the folded tube 200 corresponding to the first hook end 312, extending radially along the folded tube 200; the first hook end 312 hooks the first hook groove 210 to lock the folded tube 200; the folded tube 200 can be locked or unlocked by engaging the first hook end 312 on the hook member 310 with the hook of the first hook groove 210 or by rotating away from each other.

[0032] In an optional or preferred embodiment, the latching component 400 and the hook component 310 have the same rotation center. The pushing end 411 is located at the lower end of the latching component 400 and above the pushed end 311, with a preset distance between them in the vertical direction. The fact that the latching component 400 and the hook component 310 have the same rotation center facilitates the rotation of the latching component 400 to drive the hook component 310. The pushing end 411 is located above the pushed end 311 and with a preset distance between them in the vertical direction, so that the pushing end 411 can only drive the hook component 310 to unlock the folding tube 200 in certain positions, such as the second rotation position. For example, in the middle position between the first rotation position and the second rotation position, the hook component 310 will still lock the folding tube 200. This achieves the effect of locking the folding tube 200 even if the latching component 400 is not in the accurate locking position, such as the first rotation position, thus preventing the folding tube 200 from rotating accidentally during use.

[0033] In an optional or preferred embodiment, the latch component 400 includes a handle 410 rotatably connected to the fixing tube 100, the handle 410 having a push end 411; a positioning member 120 that is elastically movable along its own axis is provided on the side of the fixing tube 100 facing the handle 410; a pushing part 412 is provided on the handle 410 corresponding to the positioning member 120; the pushing part 412 abuts against the top of the positioning member 120; thereby enabling the handle 410 and the folding tube 200 to be elastically positioned by the pushing part 412 and the positioning member 120, so as to achieve the effect of fixing the position of the handle 410.

[0034] In an optional or preferred embodiment, the top of the positioning member 120 has an inclined surface engagement with the pushing part 412; and when the latching member 400 locks the folding tube 200, the positioning member 120 exerts an upward oblique force on the pushing part 412 toward the folding tube 200; the positioning member 120 has an elastic reset tendency after being pressured by the pushing part 412, and the inclined surface engagement between the top of the positioning member 120 and the pushing part 412 makes the positioning member 120 exert an upward oblique force on the pushing part 412 toward the folding tube 200, thereby positioning the handle 410. Since the positioning member 120 is elastically telescopically installed, it can disengage from the positioning member 120 when the pushing part 412 is subjected to a large external force.

[0035] In an optional or preferred embodiment, the top of the positioning member 120 has a convex arc surface; the pushing part 412 is configured as a rolling member rotatable about its own axis, and the rolling member has a concave arc surface matching the convex arc surface; such as Figure 5As shown, the push part 412 is configured as a rolling element that can rotate around its own axis, so that the push part 412 has rolling friction when it comes into contact with the positioning element 120, making the movement smoother. At the same time, the positioning is achieved by the concave arc surface on the push part 412 and the convex arc surface on the top of the positioning element 120, making the position of the handle 410 more accurate.

[0036] In an optional or preferred embodiment, a mounting through hole 413 extending along its own length is provided on the handle 410; a handle 420 with a second hook end 421 is movably provided in the mounting through hole 413; a second hook groove 220 is provided on the side of the folding tube 200 facing the handle 420; the second hook end 421 can hook the second hook groove 220; through the cooperation of the second hook end 421 and the second hook groove 220 on the handle 420, when the second hook end 421 and the second hook groove 220 are locked together, the first handle 410 is locked and cannot be rotated; when lifting... When the handle 420 is engaged, the second hook end 421 moves away from the second hook groove 220, thereby unlocking the first handle 410 and allowing the first handle 410 to rotate normally. The handle 420 serves as a safety component for the handle 410, preventing accidental rotation of the handle 410. At the same time, the handle 410 and the latch 310 provide double locking to the folding tube 200, further preventing accidents and ensuring safety during use. Furthermore, the rotation of the handle 410 drives the latch 310 to unlock the folding tube, eliminating the need for separate operation of the latch 310, thus making the entire process convenient and quick.
