Description

Technical Field

[0001] The utility model relates to a scooter, in particular to an adaptive front bucket connecting structure of the scooter. Background Art

[0002] As a new type of transportation tool, the market demand for scooters has increased dramatically in recent years. Its portability and light weight are welcomed by users and it has become one of the new transportation tools after bicycles. When you need to carry items, a scooter needs a cargo box to load them.

[0003] For example, Chinese utility model patent CN214112759U discloses a scooter with a warning light strip structure, which includes a frame, a front wheel installed at the front end of the frame, and a rear wheel installed at the rear end of the frame. It also includes a straight rod for controlling the direction of the front wheel, a motor for driving the front wheel to rotate, and a handlebar tube installed on the straight rod. A cargo box is provided on the straight rod, and the cargo box suspended in the air has a small storage space.

[0004] In order to increase the storage space of the cargo box and make the cargo box connected to the front side of the scooter larger, wheels are arranged at the bottom of the cargo box, and the cargo box is also placed on the ground to increase the depth of the cargo box, thereby increasing the space for placing items in the cargo box. At this time, the weight of the cargo box no longer acts on the scooter, but is supported by the wheels at the bottom. The scooter only controls the direction of the cargo box and provides a forward thrust.

[0005] The existing scooters with wheels in the front bucket have the following problems: the front bucket is directly fixed on the front side of the scooter. Since the front bucket contacts the ground through the wheels, when the scooter goes uphill, the front bucket moves up along the slope to lift the front side of the scooter, so that the front bucket and the rear wheels of the scooter lift the front part of the scooter body, and the front wheels are suspended in the air, which affects the forward movement of the scooter. When the scooter goes downhill, the front bucket will be suspended in the air, so that the gravity of the front bucket will act on the scooter again, increasing the weight of the front of the scooter, which may easily cause the rear part of the scooter body to tilt forward. In addition, when the scooter turns, the scooter body will tilt and cause the front bucket to tilt to one side, which may cause items in the front bucket to fall out. Utility Model Content

DETAILED DESCRIPTION

[0034] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0035] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0036] Figure 1-Figure 14 As shown, the adaptive scooter front bucket connection structure includes a rotating component 3, and two ends of the rotating component 3 are respectively connected to the front bucket 1 and the scooter body 4.

[0037] Figure 1 , Figure 2 As shown, the front bucket 1 has a storage space opening upward, and wheels 2 are installed on both sides of the bottom of the front bucket 1, and the front bucket 1 is supported on the ground by the wheels 2. Preferably, the wheels 2 at the bottom of the front bucket 1 are universal wheels, and when the scooter body 4 turns, the front bucket 1 can turn with the scooter body 4.

[0038] Figure 3 , Figure 4 As shown, one end of the rotating assembly 3 is connected to the rear side of the front bucket 1.

[0039] The rotating assembly 3 has a first axis 15 and a second axis 27 for relative rotation of the front bucket 1 and the scooter body 4. The first axis 15 is horizontally arranged along the X-axis direction, and the front bucket 1 can swing up and down in the vertical direction relative to the scooter body 4 around the first axis 15. The second axis 27 is perpendicular to the first axis 15, and the entire scooter body 4 can be twisted to the left or right relative to the front bucket 1 around the second axis 27 to tilt the scooter body 4.

[0040] Fig.11As shown, when the scooter goes uphill, the wheel 2 at the bottom of the front bucket 1 contacts the slope, and the front bucket 1 swings up along the slope around the first axis 15 relative to the scooter body 4 to ensure that the wheels on both the front and rear sides of the scooter body 4 are always in contact with the ground, so as to prevent the front bucket 1 and the rear wheel 8 of the scooter from lifting the front side of the scooter body 4 and making the front wheel 9 of the scooter suspended.

[0041] Fig.10 As shown, when the scooter goes downhill, the front bucket 1 naturally swings down around the first axis 15 due to its own gravity, so that the wheels 2 at the bottom of the front bucket 1 always touch the ground, avoiding the problem that the front bucket 1 is suspended in the air and the gravity acts on the front side of the scooter, causing the scooter to tip over.

[0042] Fig.12 , Fig.13 As shown, when the scooter turns to the left or right, the scooter body 4 is twisted and tilted to the left or right relative to the front bucket 1 around the second axis 27 due to the turning, and the scooter body 4 only tilts itself, and the rotating component 3 ensures that the front bucket 1 is always in a flat state.

[0043] The structure adapts to uphill and downhill terrains through the rotating component 3, so that the wheels of the scooter and the wheels 2 at the bottom of the front bucket 1 are always in contact with the ground for support, and adapts to the torsion and tilt of the scooter body 4 when turning through the rotating component 3, so that the front bucket 1 can always be in a flat state.

[0044] Figure 8 , Fig. 9 As shown, the second axis 27 can be arranged horizontally along the Y-axis direction; or the second axis 27 can be arranged tilted to form an angle with the horizontal plane, the angle is not greater than 10°, preferably, the angle formed by the second axis 27 and the horizontal plane is 6°, and the angle is denoted as a.

The rear end of the second component 5 is fixedly connected to the steering mechanism 30. When the steering mechanism 30 controls the steering of the front wheel 9, the front bucket 1 is driven by the steering mechanism 30 to steer.

[0049] Figure 5 , Figure 6 , Figure 7 , Fig.14 As shown, preferably, the end of the second component 5 is detachably connected to the steering mechanism 30 so that the front bucket 1 can be removed from the scooter body 4. The steering mechanism 30 includes a stand pipe 11 and a wheel frame 10, the wheel frame 10 is rotatably connected to the frame 7, the front wheel 9 is mounted on the wheel frame 10, a lower connecting seat 19 is provided on the wheel frame 10, an upper connecting seat 18 is provided at the lower end of the stand pipe 11, and the upper connecting seat 18 is located above the lower connecting seat 19, the rear side of the upper connecting seat 18 is hinged to the rear side of the lower connecting seat 19, an upper connecting hole 31 is provided on the front side of the upper connecting seat 18, and a lower connecting hole 32 is provided on the front side of the lower connecting seat 19.

[0050] The second joint 16 can be separated from the steering mechanism 30 by removing the connecting shaft from the first connecting hole 17 and the connecting shaft hole 23, and the connecting rod and the front bucket 1 can be removed from the front side of the scooter body 4.

[0051] The wheel frame 10 includes a front fork 25 and a rotating shaft 26 fixed to the top of the front fork 25. The front wheel 9 is mounted on the front fork 25. The front fork 25 is rotatably connected to the frame 7 through the rotating shaft 26. The above-mentioned lower connecting seat 19 is mounted on the rotating shaft 26.

[0052] Fig.14As shown, preferably, the connecting shaft is a spring pin shaft 22, and the spring pin shaft 22 passes through the connecting shaft hole 23. One end of the spring pin shaft 22 is provided with a limiting head 33 to limit it on one side of the connecting shaft hole 23, and the other end is provided with a steel ball 35 partially protruding from the circumferential side wall, and the steel ball 35 is limited on the other side of the connecting shaft hole 23.
