Description

Technical Field

[0001] This utility model relates to scooters, and more particularly to a folding scooter with a foldable control lever assembly. Background Technology

[0002] The control levers on existing scooters are often fixed to the frame and cannot be folded, which takes up a lot of space and requires a large packaging shell, consuming a lot of raw materials for the packaging shell. This is not conducive to energy conservation and environmental protection. At the same time, it is not conducive to warehousing and transportation during the production and sales stages, nor to storage and carrying during use. Summary of the Invention

[0003] The purpose of this utility model is to solve the above-mentioned problems existing in the prior art and provide a folding scooter. The scooter comprises a lower control lever assembly and an upper control lever assembly, and a folding locking mechanism is added between the lower and upper control lever assemblies. The overall structure of the folding locking mechanism is reasonably designed and works reliably. When the upper control lever assembly is placed on the lower control lever assembly and locked by the folding locking mechanism, the control lever assembly is used to control the steering wheel to steer the scooter, enabling normal use. When the folding locking mechanism is unlocked, the upper control lever assembly swings downward with the folding locking mechanism as the swing fulcrum and rests against the vehicle body, so that the control lever assembly is in a folded state, reducing the overall volume and facilitating warehousing, transportation, storage, and carrying.

[0004] The above-mentioned technical objective of this utility model is mainly achieved through the following technical solution: a folding scooter, comprising a vehicle body with wheels, an operating lever assembly cooperating with the vehicle body and a steering wheel for adjusting direction, the operating lever assembly being used to control the steering wheel to turn, characterized in that the operating lever assembly includes a lower operating lever assembly and an upper operating lever assembly, the lower operating lever assembly and the upper operating lever assembly being connected by a folding locking mechanism, the lower operating lever assembly cooperating with the steering wheel, the folding locking mechanism being used to make the upper operating lever assembly stand on the lower operating lever assembly and lock it for controlling the steering wheel to turn, or the folding locking mechanism being unlocked, causing the upper operating lever assembly to swing downward with the folding locking mechanism as a swing fulcrum and abut against the vehicle body, so that the operating lever assembly is in a folded state.

[0005] The difference between this technical solution and existing technologies lies in that the operating lever assembly consists of a lower operating lever assembly and an upper operating lever assembly, with a folding locking mechanism added between the two. The overall structure of the folding locking mechanism is reasonably designed and operates reliably.

[0006] When the upper control lever assembly is placed on the lower control lever assembly and locked by the folding locking mechanism, the control lever assembly is used to control the steering wheel to steer, enabling the scooter to be used normally. When the folding locking mechanism is unlocked, the upper control lever assembly swings downward with the folding locking mechanism as the swing fulcrum and abuts against the vehicle body, so that the control lever assembly is in a folded state, reducing the overall volume and facilitating warehousing, transportation, storage and carrying.

[0007] As a further improvement and supplement to the above technical solution, the present invention adopts the following technical measures:

[0008] Preferably, the lower operating lever assembly includes a lower operating lever, the upper operating lever assembly includes an upper operating lever, and the folding locking mechanism is disposed between the lower and upper operating levers. The folding locking mechanism is used to lock the upper operating lever on the lower operating lever, or to unlock the folding locking mechanism, allowing the upper operating lever to swing downwards about the folding locking mechanism as a pivot point and abut against the vehicle body, thus folding the operating lever assembly. The lower operating lever is often connected to the bracket of the steering wheel on the scooter. To reduce the number of parts and facilitate production, processing, and disassembly, the lower operating lever and the bracket are an integral structure. The vehicle body has an operating lever through-hole, and the upper end of the lower operating lever extends upwards from below the operating lever through-hole. The inner wall of the operating lever through-hole cooperates with the side wall of the lower operating lever, allowing the lower operating lever to rotate within the operating lever through-hole.

[0009] Preferably, the folding locking mechanism includes an upper locking seat disposed on the upper operating lever, a lower locking seat disposed on the lower operating lever, an upper locking tongue disposed on the upper locking seat, a lower locking tongue disposed on the lower locking seat, a reset member, and a locking / unlocking assembly. The reset member cooperates with the lower locking tongue, and the upper locking tongue and the lower locking tongue cooperate with each other. The locking / unlocking assembly is used to release the force acting on the lower locking tongue, so that the upper locking tongue can disengage from the lower locking tongue for folding, or the upper locking tongue and the lower locking tongue form a locking engagement; or, the locking / unlocking assembly is used to lock the lower locking tongue, and to keep the upper locking tongue and the lower locking tongue locked together.

[0010] Preferably, the locking and unlocking assembly includes a push-pull rod, an anti-disengagement component, and an adjusting handle. The first end of the push-pull rod passes through the lower locking seat and the lower locking tongue, and is connected to the anti-disengagement component. The anti-disengagement component is disposed on the outside of the lower locking tongue. The second end of the push-pull rod is pivotally connected to the push-pull rod. The pivot hole on the adjusting handle is eccentrically positioned. When the adjusting handle is perpendicular to the push-pull rod, the pivot hole is away from the lower locking seat, used to tighten the lower locking tongue, so that the lower locking tongue and the upper locking tongue form a locking engagement. When the adjusting handle is coaxial with the push-pull rod, the pivot hole is close to the lower locking seat, used to release the pulling force acting on the lower locking tongue, so that the upper locking tongue can disengage from the lower locking tongue, or the upper locking tongue can form a locking engagement with the lower locking tongue.

[0011] Preferably, the locking and unlocking assembly further includes a bearing seat, the first end of which is cylindrical and the second end is annular. The bearing seat is in the shape of an ingot, and the surface of the bearing seat facing the second end is curved. The two opposite ends of the curved surface extend toward the second end. When the folding locking mechanism is in the locked state, the annular surface of the second end fits against the curved surface, and the two outwardly extending ends of the curved surface fit against the second end. When the folding locking mechanism is in the unlocked state, the two outwardly extending ends disengage from the annular surface of the second end, and the annular surface of the second end engages with the concave portion of the curved surface.

[0012] Preferably, the lower lock seat is provided with a mounting groove, and a mounting base is provided in the mounting groove. The mounting base includes a bottom ring, a retaining ring with the outer edge of the bottom ring folded outward, and a mounting cavity formed by the bottom ring and the retaining ring. The bottom ring has a through hole in the middle. The shaft seat is disposed in the mounting cavity. The axial height of the retaining ring is adapted to the minimum thickness of the shaft seat. The push-pull rod passes through the through hole.

[0013] Preferably, the push-pull rod further includes a connecting segment with a rectangular cross-section connecting the first end and the second end, the thickness of the connecting segment being adapted to the thickness of the second end, and the radius of the circumcircle of the cross-section of the connecting segment being matched with the radius of the first end.

[0014] Preferably, the push-pull rod further includes a locking protrusion, which is disposed on the outer ring wall of the second end. The locking protrusion abuts against the lower end of the adjusting handle to limit the swing direction of the adjusting handle.

[0015] Preferably, the upper end of the upper locking tongue is fixed to the upper locking seat, the lower end of the upper locking tongue is provided with an upper hook portion with the hook opening facing outward, the upper end of the lower locking seat is provided with a lower hook portion with the hook opening facing inward, the lower part of the lower locking seat is pivotally connected to the lower locking seat via a pivot, the outer end of the reset member engages with the lower locking seat, the inner end of the reset member abuts against the interior of the lower locking seat, the upper hook portion pushes the lower hook portion to cause the lower locking seat to swing about the pivot axis, so that the upper hook portion disengages from the lower hook portion, or the upper hook portion hooks and engages with the lower hook portion.

[0016] Preferably, the upper operating lever is provided with a latch. When the folding locking mechanism is in the locked state, the adjusting handle on the folding locking mechanism is locked in place with the latch, and the latch is used to lock the position of the adjusting handle.

[0017] The beneficial effects of this utility model are as follows: the lower operating lever assembly and the upper operating lever assembly constitute an operating lever assembly, and a folding locking mechanism is added between the lower operating lever assembly and the upper operating lever assembly. The overall structure of the folding locking mechanism is reasonably designed and works reliably. When the upper operating lever assembly is placed on the lower operating lever assembly and locked by the folding locking mechanism, the operating lever assembly is used to control the steering wheel to steer, so that the scooter can be used normally. When the folding locking mechanism is unlocked, the upper operating lever assembly swings downward with the folding locking mechanism as the swing fulcrum and abuts against the vehicle body, so that the operating lever assembly is in a folded state, reducing the overall volume and facilitating warehousing, transportation, storage and carrying.

Detailed Implementation

[0024] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0025] Example: Figures 1-5 As shown, a folding scooter includes a frame 1 with wheels, and an operating lever assembly that cooperates with the frame 1 and a steering wheel 2 for adjusting direction. The operating lever assembly is used to control the steering wheel 2 to steer.

[0026] The difference between this technical solution and the prior art is that the operating lever assembly includes a lower operating lever 4 assembly and an upper operating lever 3 assembly. The lower operating lever 4 assembly and the upper operating lever 3 assembly are connected by a folding locking mechanism. The lower operating lever 4 assembly cooperates with the steering wheel 2. The folding locking mechanism is used to make the upper operating lever 3 assembly stand on the lower operating lever 4 assembly and lock it for controlling the steering wheel 2 to turn. Alternatively, the folding locking mechanism can be unlocked, allowing the upper operating lever 3 assembly to swing downward with the folding locking mechanism as the swing fulcrum and abut against the vehicle body 1, so that the operating lever assembly is in a folded state.

[0027] In other words, the control lever assembly consists of a lower control lever 4 assembly and an upper control lever 3 assembly, and a folding locking mechanism is added between the lower control lever 4 assembly and the upper control lever 3 assembly.

[0028] In this technical solution, the folding locking mechanism has a reasonable overall structural design, a compact structure, and reliable operation.

[0029] After the scooter is assembled, the upper control lever 3 assembly is placed on the lower control lever 4 assembly and locked by the folding locking mechanism. The control lever assembly is used to steer the steering wheel 2, enabling normal use of the scooter. When the folding locking mechanism is unlocked, the upper control lever 3 assembly swings downwards around the folding locking mechanism as a pivot point and rests against the vehicle body 1, folding the control lever assembly to reduce its overall size and facilitate storage, transportation, and carrying.

[0030] In this technical solution, the upper end of the upper operating lever 3 assembly is provided with a handle to facilitate user operation of the operating lever assembly. When the upper operating lever 3 assembly is placed on the lower operating lever 4 assembly, the overall height of the upper operating lever 3 assembly and the lower operating lever 4 assembly is adapted to the user's operation of the operating lever assembly.

[0031] Of course, the upper control lever 3 assembly and / or the lower control lever 4 assembly can also be equipped with a height adjustment mechanism to adjust the overall height of the control lever assembly to suit users of different heights.

[0032] Next, the above technical solution will be explained in detail:

[0033] In practical applications, the lower operating lever 4 assembly includes a lower operating lever 4, the upper operating lever 3 assembly includes an upper operating lever 3, and the folding locking mechanism is disposed between the lower operating lever 4 and the upper operating lever 3. The folding locking mechanism is used to make the upper operating lever 3 stand on the lower operating lever 4 and lock it, or to unlock the folding locking mechanism so that the upper operating lever 3 swings downward with the folding locking mechanism as the swing fulcrum and abuts against the vehicle body 1, so that the operating lever assembly is in a folded state.

[0034] In this technical solution, the lower operating lever 4 is often connected to the bracket of the steering wheel on the scooter. To reduce the number of parts and facilitate production, processing, and disassembly, the lower operating lever 4 and the bracket are integrated into one structure. The vehicle body 1 is provided with an operating lever through-hole. The upper end of the lower operating lever 4 extends upward from below the operating lever through-hole. The inner wall of the operating lever through-hole cooperates with the side wall of the lower operating lever 4, allowing the lower operating lever 4 to rotate within the operating lever through-hole.

[0035] In practical applications, the folding locking mechanism includes an upper locking seat 5 disposed on the upper operating lever 3, a lower locking seat 6 disposed on the lower operating lever 4, an upper locking tongue 7 disposed on the upper locking seat 5, a lower locking tongue 8, a reset member 9, and a locking / unlocking assembly disposed on the lower locking seat 6. The reset member 9 cooperates with the lower locking tongue 8, and the upper locking tongue 7 cooperates with the lower locking tongue 8. The locking / unlocking assembly is used to release the force acting on the lower locking tongue 8, so that the upper locking tongue 7 can be disengaged from the lower locking tongue 8 for folding, or the upper locking tongue 7 and the lower locking tongue 8 can form a locking engagement; or, the locking / unlocking assembly is used to lock the lower locking tongue 8, so that the upper locking tongue 7 and the lower locking tongue 8 can maintain a locked engagement.

[0036] In this technical solution, the reset component 9 is a tension spring, so that the lower locking tongue 8 is not subjected to external force and remains in contact with the lower locking seat 6.

[0037] In practical applications, the locking and unlocking assembly includes a push-pull rod 10, an anti-disengagement component 11, and an adjusting handle 12. The first end 13 of the push-pull rod 10 passes through the lower locking seat 6 and the lower locking tongue 8, and is connected to the anti-disengagement component 11. The anti-disengagement component 11 is located on the outside of the lower locking tongue 8. The push-pull rod 10 and its second end 14 are connected by a pivot. The pivot hole 15 on the adjusting handle 12 is eccentrically positioned. When the adjusting handle 12 is perpendicular to the push-pull rod 10, the pivot hole 15 is away from the lower locking seat 6, which is used to tighten the lower locking tongue 8, so that the lower locking tongue 8 and the upper locking tongue 7 form a locking engagement. When the adjusting handle 12 is coaxial with the push-pull rod 10, the pivot hole 15 is close to the lower locking seat 6, which is used to release the pulling force acting on the lower locking tongue 8. The upper locking tongue 7 can disengage from the lower locking tongue 8, or the upper locking tongue 7 can form a locking engagement with the lower locking tongue 8.

[0038] In this technical solution, the push-pull rod 10 is threadedly connected to the anti-detachment component 11, which can be a bolt.

[0039] In this technical solution, to further reduce the folded volume, the length of the lower operating lever 4 on the lower operating lever 4 assembly is often set to a relatively short structure. In practical applications, the lower lock seat 6 is often positioned close to the vehicle body 1. Therefore, in this technical solution, when the folding locking mechanism is locked, the adjusting handle 12 is aligned with the upper operating lever 3.

[0040] When the upper operating lever 3 is flipped down and is in a horizontal (or approximately horizontal) state, the push-pull lever 10 loses the outward pulling force of the adjusting handle 12, and the push-pull lever 10 is in a relaxed state. When the upper operating lever 3 is operated, the upper locking tongue 7 exerts an outward pushing force on the lower locking tongue 8 (here, "outward" refers to the direction away from the axis of the upper (lower) operating lever), causing the upper end of the lower locking tongue 8 to swing outward. The upper locking tongue 7 can disengage from or engage with the lower locking tongue 8, facilitating the folding or uprighting of the operating lever assembly. When the operating lever assembly is upright, the adjusting handle 12 is then swung upward to fit against the upper operating lever 3. The push-pull lever 10 is pulled by the adjusting handle 12 and moves in the direction away from the lower locking tongue 8. The lower locking tongue 8 is pulled by the push-pull lever 10, and the lower locking tongue 8 fits tightly against the lower locking seat 6, achieving the locked state.

[0041] In practical applications, the locking and unlocking assembly further includes a bearing seat 16. The first end 13 is cylindrical, the second end 14 is annular, and the bearing seat 16 is ingot-shaped. The surface of the bearing seat 16 facing the second end 14 is curved, and the two opposite ends on the curved surface extend toward the second end 14. When the folding locking mechanism is in the locked state, the annular surface of the second end 14 fits against the curved surface, and the two outwardly extending extension ends 17 on the curved surface fit against the second end 14. When the folding locking mechanism is in the unlocked state, the two extension ends 17 disengage from the annular surface of the second end 14, and the annular surface of the second end 14 engages with the concave portion of the curved surface.

[0042] In this technical solution, the ingot-shaped bearing seat 16 is beneficial for limiting the push-pull rod 10 to the locked position, ensuring the reliable locking of the folding locking mechanism, and improving the stability, reliability and safety of the folding scooter.

[0043] When the folding locking mechanism is in the locked state, the outer end 17 keeps the push-pull rod 10 away from the lower locking tongue 8. When the folding locking mechanism is in the unlocked state, the second end 14 of the push-pull rod 10 is inserted into the ingot-shaped recess of the bearing seat 16, causing the push-pull rod 10 to move a certain distance toward the lower locking tongue 8, so that the lower locking tongue 8 loses the pulling force of the push-pull rod 10.

[0044] In this technical solution, the first end 13 is cylindrical, which helps to ensure that the push-pull rod 10 can move back and forth smoothly along its axial direction. The second end 14 is annular, which facilitates pivoting with the lower end of the adjusting handle 12 (which has an eccentric pivot hole 15 to form a cam structure).

[0045] In practical applications, to ensure that the bearing seat 16 is stably installed on the lower locking seat 6 and to keep the outer extension end 17 on the bearing seat 16 in the upper and lower positions, the lower locking seat 6 is provided with a mounting groove 18, and a mounting base 19 is provided in the mounting groove 18. The mounting base 19 includes a bottom ring 20, a retaining ring 21 with the outer edge of the bottom ring 20 folded outward, and a mounting cavity formed by the bottom ring 20 and the retaining ring 21. The bottom ring 20 has a through hole 23 in the middle. The bearing seat 16 is disposed in the mounting cavity. The axial height of the retaining ring 21 is adapted to the minimum thickness of the bearing seat 16. The push-pull rod 10 passes through the through hole 23.

[0046] In practical applications, the push-pull rod 10 also includes a connecting segment 24 with a rectangular cross-section that connects the first end 13 and the second end 14. The thickness of the connecting segment 24 is adapted to the thickness of the second end 14, and the radius of the circumcircle of the cross-section of the connecting segment 24 matches the radius of the first end 13.

[0047] In this technical solution, the cross-section of the connecting section 24 is rectangular, which facilitates the installation of the adjusting handle 12, determines the rotation direction of the adjusting handle 12, and facilitates the axial movement of the push-pull rod 10 as the adjusting handle 12 rotates.

[0048] In practical applications, in order to further ensure the locking reliability of the folding locking mechanism, the push-pull rod 10 also includes a locking protrusion 25. The locking protrusion 25 is disposed on the outer ring wall of the second end 14. The locking protrusion 25 abuts against the lower end of the adjusting handle 12 to limit the swing direction of the adjusting handle 12.

[0049] In practical applications, the upper end of the upper locking tongue 7 is fixed to the upper locking seat 5, the lower end of the upper locking tongue 7 is provided with an upper hook portion with the hook opening facing outwards, the upper end of the lower locking seat 6 is provided with a lower hook portion with the hook opening facing inwards, the lower part of the middle of the lower locking seat 6 is pivotally connected to the lower locking seat 6 via a pivot, the outer end of the reset member 9 cooperates with the lower locking seat 6, the inner end of the reset member 9 abuts against the interior of the lower locking seat 6, the upper hook portion pushes the lower hook portion to make the lower locking seat 6 swing around the pivot axis, so that the upper hook portion disengages from the lower hook portion, or makes the upper hook portion hook and engage with the lower hook portion.

[0050] In practical applications, in order to prevent the adjustment handle 12 from being subjected to unexpected external forces and to further improve the locking reliability of the folding locking mechanism, the upper operating lever 3 is provided with a latch 26. When the folding locking mechanism is in the locked state, the adjustment handle 12 on the folding locking mechanism is locked in place with the latch 26. The latch 26 is used to lock the position of the adjustment handle 12.

[0051] In this technical solution, a locking opening is provided on the side wall of the latch 26. The adjusting handle 12 is aligned with the locking opening and rotates around the upper operating rod 3 to enter the locking cavity of the latch 26, forming a locking engagement.

[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Various modifications and variations can be made to the above embodiments. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
