Description

Technical Field

[0001] This utility model relates to a handlebar folding structure, and more particularly to a handlebar folding structure and a bicycle or scooter having a handlebar folding structure. Background Technology

[0002] Currently, scooters and bicycles are generally used for daily commuting. Scooters are more suitable for short-distance urban commuting and improving flexibility, while bicycles are more focused on medium- and long-distance travel and physical exercise.

[0003] Numerous bicycles and scooters with folding functions have been launched on the market to improve portability, facilitate storage, and allow easy placement in car trunks for transportation. To minimize size, patent application number 2016201668359 discloses a handlebar folding mechanism suitable for personal mobility vehicles. This utility model includes a handlebar, a spring, a locking ring, a connecting block, and a handlebar body. One end of the connecting block is hinged to the handlebar body, and the other end is connected to the handlebar. The locking ring is movably fitted onto the outside of the connection between the connecting block and the handlebar. The spring is located inside the locking ring. When folding, pulling the locking ring outward compresses the spring, separating the locking ring from the handlebar body. Rotating the handlebar downward rotates the connecting block, folding the handlebar to a vertical position. The locking ring, under the action of the spring, abuts against the side of the handlebar body for positioning. When unfolding, rotating the handlebar rotates the connecting block to a horizontal position, and the locking ring, under the elastic force of the spring, slides and engages with the handlebar body for positioning. This structure has the following disadvantages: First, the sliding structure will cause severe internal wear during use, resulting in larger gaps and causing the handle to wobble; Second, the force is concentrated on the upper inner side and the lower outer side during use, and the uneven force can easily cause the locking ring to deform; Third, the locking ring is a hollow structure, which has low strength and poor load-bearing capacity; Fourth, the locking ring is a sliding structure, and there is also the possibility of accidental slippage during use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a handlebar folding structure and a bicycle or scooter with a handlebar folding structure.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: The handle folding structure includes a vertical rod for mounting the handle, a left handle, and a right handle. The left and right handles are hinged to the vertical rod and have a gap at their inner ends. A locking seat is movably mounted on the vertical rod at the gap between the inner ends of the left and right handles. When the locking seat is located at the gap between the inner ends of the two handles, its two sides abut against the inner ends of the two handles to restrict the two handles from flipping and folding. When the locking seat moves out of the gap between the inner ends of the two handles, the two handles can be flipped and folded around their respective hinge positions.

[0006] Preferably, a pull-down device is provided on or inside the upright, with one end of the pull-down device connected to the upright and the other end connected to the lower side of the clamping seat to limit the clamping seat to the gap between the two handles.

[0007] Preferably, the pull-down device is elastic, allowing the locking seat to be pulled up and moved out of the gap between the two handles, thus releasing the restriction on the two handles.

[0008] Preferably, the pull-down device is an elastic rope, a tension spring, or a combination of a rope and a tension spring, or a combination of a tension spring and a hook.

[0009] Preferably, the clamping seat is slidably mounted on or inside the upright, and an anti-detachment structure is provided between the clamping seat and the upright.

[0010] Preferably, the anti-disengagement structure includes a limiting hole provided on the clamping seat and a limiting pin provided on the upright, the limiting pin passing through the limiting hole to limit the travel of the clamping seat by the length of the limiting hole.

[0011] Preferably, the upright is provided with a hinge seat, which is provided with a T-shaped opening consisting of a horizontal opening and a vertical opening. Two handles are hinged at the horizontal opening and a locking seat is provided in the middle of the horizontal opening and can slide up and down at the vertical opening. The bottom sides of the horizontal opening limit the upward flipping of the two handles. The bottom outer side of the horizontal opening is provided with a notch extending to the inside of the hinge of the two handles for the two handles to flip downward.

[0012] Preferably, the upright or the hinged seat is provided with a lever-type actuating structure and both are provided with a notch to allow the lever-type actuating structure to rotate. The clamping seat is provided with an actuating groove, and the inner end of the lever-type actuating structure extends into the actuating groove. When the lever-type actuating structure is actuated to rotate in the notch, its inner end will push the clamping seat upward.

[0013] Preferably, the inner ends of both handles are planes perpendicular to the axis, and the clamping seat is in contact with the inner end faces of the two handles when it is located at the gap between the inner ends of the two handles.

[0014] A bicycle or scooter with a handlebar folding structure, including a frame and the aforementioned handlebar folding structure, with a pole mounted on the frame.

[0015] Compared with the prior art, the advantages of this utility model are as follows: This application sets the handles on both sides as a hinge structure and leaves a gap at the inner end of the handle. Then, by movably setting the locking seat, when the locking seat moves to the gap, it abuts against the inner end of the two handles to limit the rotation of the handle. When the locking seat moves out of the gap, the two handles can be flipped and folded. In addition, by setting a lever-type actuation structure, the locking seat can be pushed upward with less effort to achieve the purpose of saving effort. Attached Figure Description

Detailed Implementation

[0018] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0019] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures. Example

[0020] This embodiment mainly describes the handlebar folding structure and the title of the bicycle or scooter with the handlebar folding structure, as follows: See attached document Figures 1-6A folding handle structure includes a vertical rod 10 for mounting handles, a left handle 201, and a right handle 202. The left handle 201 and right handle 202 are hinged to the vertical rod 10, and their inner ends have a gap. A locking seat 30 is movably mounted on the vertical rod 10, located at the gap between the inner ends of the left handle 201 and right handle 202, and is limited in the gap by a limiting structure to prevent detachment. When the locking seat 30 is located at the gap between the inner ends of the two handles, its two sides abut against the inner ends of the two handles, restricting the two handles from flipping and folding. When the locking seat 30 moves out of the gap between the inner ends of the two handles, the two handles can flip and fold around their respective hinge positions. This design sets the handles on both sides as hinged structures and leaves a gap at the inner end of the handles. A locking seat 30 is movably installed at the gap. When the locking seat 30 moves to the gap, it abuts against the inner end of the two handles to limit the handles from rotating. When the locking seat 30 moves out of the gap, the two handles can be flipped and folded. The lower limiting structure limits the locking seat 30 to prevent it from disengaging from the gap.

[0021] Preferably, the limiting structure is a pull-down device 60 installed on or inside the upright 10. One end of the pull-down device 60 is connected to the upright 10, and the other end is connected to the lower side of the clamping seat 30, thus limiting the clamping seat 30 to the gap between the two handles. The pull-down device 60 can be an elastic structure or a non-elastic structure. The elastic structure applies a downward pulling force to the clamping seat 30 to prevent it from disengaging from the gap, while the non-elastic structure uses a fixed-disassembly or locking-releasing method to limit the clamping seat 30.

[0022] Preferably, the pull-down device 60 is elastic, allowing the locking seat 30 to be pulled upwards and moved out of the gap between the two handles, thus releasing the restriction on the two handles. Specifically, the pull-down device 60 is an elastic rope, a tension spring 601, or a combination of a rope and a tension spring 601, or a combination of a tension spring 601 and a hook 602.

[0023] Preferably, the clamping seat 30 is slidably disposed on or inside the upright 10, and an anti-disengagement structure is provided between the clamping seat 30 and the upright 10. Preferably, the upright 10 is configured as a hollow structure so that the pull-down device 60 is disposed inside the upright 10, while the clamping seat 30 is slidably disposed on the top of the upright 10. Preferably, the anti-disengagement structure includes a limiting hole 302 disposed on the clamping seat 30 and a limiting pin 603 disposed on the upright 10, the limiting pin 603 passing through the limiting hole 302 to limit the travel of the clamping seat 30 by the length of the limiting hole 302.

[0024] Preferably, the upright 10 is provided with a hinge seat 40, which has a T-shaped opening consisting of a horizontal opening and a vertical opening. Two handles are hinged at the horizontal opening, and a locking seat 30 is located in the middle of the horizontal opening and can slide up and down at the vertical opening. The bottom surfaces on both sides of the horizontal opening limit the upward flipping of the two handles. The bottom outer side of the horizontal opening has a notch 402 extending to the inside of the hinge point of the two handles for the downward flipping of the two handles. In this design, the hinge seat 40 restricts the flipping direction of the handles, allowing them to flip vertically downwards only to get closer to the upright 10 and reduce volume.

[0025] Preferably, the upright 10 or the hinge seat 40 is provided with a lever-type actuating structure 50, and both have notches 101 and 401 for the lever-type actuating structure 50 to rotate. The locking seat 30 is provided with an actuating groove 301. The inner end of the lever-type actuating structure 50 extends into the actuating groove 301. When the lever-type actuating structure 50 is actuated to rotate within the notches 101 and 401, its inner end will push the locking seat 30 upward. In this design, the lever-type actuating structure 50 is a small hinged handle. The outer end of the small handle is longer than the inner end, with the hinge point as the boundary. When rotating, the lever principle is used to push the locking seat 30 on or inside the upright 10 upward and lift it up, which is more labor-saving when using it.

[0026] Preferably, the inner ends of both handles are planes perpendicular to the axial direction, and the locking seat 30 is located at the gap between the inner ends of the two handles, abutting against the inner end faces of the two handles. Since the inner ends of both handles are planes perpendicular to the axial direction, and the locking seat 30 slides vertically, the forces exerted by the two handles on the locking seat 30 after locking cancel each other out.

[0027] It should be noted that the folding method shown in the attached diagram includes the following steps: 1. By rotating the lever-type actuating structure 50 within its notches 101 and 401, the locking seat 30 is lifted upward; 2. Fold both handles downwards; 3. After folding, the lever-type actuation structure 50 is reset, and the locking seat 30 slides downward and resets under the action of the tension spring 601. Example

The pole and frame can be configured as a fixed structure, a telescopic structure, a folding structure, or are part of the frame.

[0029] The foregoing has provided a detailed description of the handle folding structure and the bicycle or scooter with the handle folding structure provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The above description of the embodiments is only for the purpose of helping to understand this utility model and its core ideas.
