Problems solved by technology

[0004] Existing folding bicycles generally adopt the folding method in which the front and rear wheels are close together on the same plane. The disadvantage is that when the vehicle is pushed after being folded, in addition to pushing the vehicle, human hands also need to assist the vehicle to prevent the vehicle from tipping over.
Its disadvantages are: the manufacturing process requirements of the sliding rod and the guide rod are high, and the manufacturing cost is high
Its potential defects are: the handlebar straight tube is responsible for controlling the direction and needs to be rotated during driving, and the slider cannot be locked. The slider and the handlebar straight tube can still rotate and slide relative to each other in the driving state. The impact of the impact makes the slider and the straight tube of the handlebar slide relative to each other, causing the frame to fold, which challenges the stability of the frame and the safety of driving
[0008] In a nutshell, there is still a lack of a combination of: simple structure, high reliability, simple and fast folding operation, good stability, high safety performance, easy to push by hand, can be pushed and pulled up stairs, small footprint after folding, and suitable for use. Folding scooter with wide range and good production technology

Embodiment 1

[0063] The dedicated part of Embodiment 1:

[0064] like( figure 1 ), ( figure 2 )and( image 3 ), it is a folding electric scooter.

[0065] In addition to the above common parts, it also includes: rear wheel bar (7), rear wheel bar locking slider (8), locking slider connecting rod (9), tripod (10), frame folding locking device (11), Storage battery (12) and foldable pedal (13).

[0066] The two ends of the rear wheel bar (7) are respectively connected in rotation with the two rear wheels (5), so that the two rear wheels (5) become free driven wheels. The middle part of the rear wheel bar (7) is horizontally connected with one end of the moving bar (4-3) for axial rotation, so that the two rear wheels (5) can move along the axis of the moving bar (4-3) through the rear wheel bar (7). to counteract part of the irregular vibrations from the road surface. For example, when the right rear wheel hits a rock during driving, the right rear wheel is raised, and the rear wheel b...

Embodiment 2

[0069] The dedicated part of the second embodiment:

[0070] like( Figure 8 ), ( Figure 9 )and( Figure 10 ), it is a folding bicycle.

[0071] In addition to the applicable general parts above, it also includes: kickstand (10), frame folding locking device (11), crank pedal (14), chain wheel set or pulley set (15), rear axle (16) and freewheel (17), it is characterized in that: rear axle (16) is rigidly connected with the inner sleeve of flywheel (17), and one end of rear axle (16) is rigidly connected with a rear wheel (5), making this wheel the drive wheel of bicycle, The other end of the rear wheel shaft (16) is rotationally connected with another rear wheel (5), and this wheel is used as a free driven wheel, and the axial direction of the rear wheel shaft (16) and one end of the moving bar (4-3) use a bearing to form a rotation connect. In this way, the two rear wheels can have a speed difference when turning, making the vehicle turn more smoothly, such as ( Figu...

Embodiment 3

[0074] The special part of embodiment three:

[0075] like( Figure 11 ), ( Figure 12 )and( Figure 13 ), it is a plate-type folding electric scooter.

[0076] In addition to the above applicable general parts, it also includes: frame folding locking device (11), battery (12), shelf (18), characterized in that: the fixed bar (4-2) is a three-headed bar, and one end is a converging head One end of the slide bar (4-1) is rotationally connected, and the other end is a separate coaxial joint with the moving bar (4-3). The moving bar (4-3) is a plate structure bar, and one end of the plate is connected to The slider (4-4) is rotationally connected, and the two sides of the other end of the plate are respectively rotationally connected with the two rear wheels (5) on the same axis, and the two sides of the plate are close to the rear wheels and the two ends separated from the fixed bar (4-2) They are respectively coaxially rotatably connected. like( Figure 11 ) shown. The p...

Abstract

The invention relates to a folding bicycle, which is a folding bicycle for transportation, comprising: a handlebar (1), a front fork (2), a front wheel (3), a foldable vehicle frame (4), a rear wheel (5), It is characterized in that: the foldable vehicle frame (4) comprises: a sliding bar (4‑1), a fixed bar (4‑2), a moving bar (4‑3) and a slider (4‑4), the sliding One end of the bar (4-1) is rotatably connected with one end of the fixed bar (4-2), and the other end of the fixed bar (4-2) is rotatably connected with the position near the end of the moving bar (4-3), and the moving bar The other end of (4-3) is rotationally connected with the slide block (4-4), and the slide block (4-4) is sleeved with the slide bar (4-1) to form a sliding connection, and the slide block (4-4) is set A locking device is provided to lock the slide block (4-4) in a specific position on the slide bar (4-1). The folding scooter is suitable for many different purposes. After being folded, only the coaxial double rear wheels touch the ground, becoming a trolley.

Description

technical field [0001] The invention relates to a folding car, in particular to a folding car for walking, which belongs to the technical field of trackless land vehicles. Background technique [0002] At present, existing folding bicycles for walking are generally folding bicycles or electric folding bicycles designed on the basis of folding bicycles. [0003] Folding bicycles, the previous design concept, often pursue the continuous reduction of product volume, so that the existing folding bicycles generally need to be folded many times, the structure is complicated, and it is not convenient to use. With the expansion of people's life circle and the continuous improvement of rail transit, the era of people cycling to work has become history. Folding bicycles are often used in conjunction with public transportation for short distances, forming a new travel mode: family->bike->subway- > Cycling -> Destination. From the analysis of the use status and environment...
