Description

a folding bike

technical field

The present invention relates to a bicycle, in particular to a small and exquisite folding bicycle which can be folded and each part of the frame can rotate freely with each other after the locking structure is released.

Background technique

In response to the increasing shortage of energy and the increase in energy costs, energy conservation and environmental protection have become particularly important. It is imperative to reduce energy use in every industry, including the transportation industry, which constitutes 28% of the total energy use. particularly prominent. Although public transportation is usually available, and public transportation can effectively reduce transportation costs and environmental pollution, there are still some problems that limit whether consumers are willing to take public transportation instead of self-driving cars.

One of the most important issues is that of the first and last mile. If people want to use public transportation, they have to go to the bus station first. Generally, the location of the bus station is some distance from the home or office. To get to the bus station, people may have to walk or ride a bicycle, which will take more time. Maybe they can drive to the bus station. The bus station, but this has to pay parking fees, which increases the transportation cost. If a person drives or rides a bicycle to a bus stop, then the car or bicycle has to stay near the bus stop, and the person lacks transportation from the place where he or she gets off the bus to the final destination.

Therefore, people need a vehicle that can be carried with them to take them from home to the last station, which can be folded and light, so that it can be taken on public transport, and can be taken to the final destination from the next station. Electric vehicles and bicycles are usually relatively bulky and inconvenient to carry on the bus. Although there are individual light electric vehicles, it is still inconvenient for users to fold them through multiple steps.

detailed description

In order to facilitate a further understanding of the structure and effects of the present invention, preferred embodiments are described in detail below in conjunction with the accompanying drawings.

The invention relates to a foldable personal vehicle, which has the characteristics of convenient operation, light weight and space saving, and is easy to carry on the public transportation system to solve the problems of the first kilometer and the last kilometer. One embodiment of the frame structure is shown in FIGS. 1-3 , while another embodiment is shown in FIG. 7 . The common fixing structure 20 is shown in FIGS. 4-6 .

Figure 1 shows a first embodiment of a folding bicycle 100 of the present invention. In the steering column 1 there is a steering shaft 2 . The steering member 31 is connected to one end of the steering shaft 2 , and the first wheel 35 is connected to the other end of the steering shaft 2 . This enables the rider to turn the first wheel 35 by turning the steering member 31 to drive the steering shaft 2 . Due to this concentric structure, the steering column 1 does not rotate when the rider turns a corner. The steering member 31 may be a handle, a steering wheel or other suitable structures.

Both the first wheel 35 and the second wheel 37 can be composed of at least one wheel, and can also include a driving mechanism 41 , such as an electric or fuel engine to drive the folding bike 100 . A battery and power control unit 39 may be used to control the drive mechanism 41 . Although the battery and power control unit 39 is shown here mounted on the rear of the collapsible bike 100, it will be apparent in the art that the precise location of the battery and power control unit 39 need not be so limited that it can be placed in place on the car to distribute weight more evenly. A vehicle speed controller may be included on the steering member 31 or on the pedals 36 . The steering member 31 or the pedals 36 may include a brake mechanism 43 to stop the folding bike 100 .

Connected to the steering column 1 at pivotal connection point A is an upper cross support member consisting of a first upper section 7-1 and a second upper section 7-2. This connection point allows the rotation of the first upper section 7 - 1 relative to the steering column 1 . Connected to the steering column 1 at the rotatable connection point D is the lower cross support member 3 . The relative position of up and down is determined with reference to the connection position on the steering column.

The first upper section 7-1 is connected to the second upper section 7-2 at a rotatable connection point B-1. And this connection also allows rotational movement, when the foldable bicycle 100 is set on board, the first upper section 7-1 and the second upper section 7-2 are fixed by the fixed structure 20, and the fixed structure 20 is fixed with reference to Fig. 4- Figure 6 will be described in further detail. The second upper section 7 - 2 is also connected to the second wheel 37 .

The lower cross support member 3 is also rotatably connected with the second upper section 7 - 2 at the rotatable connection point C, and is further connected with the seat cushion bracket 17 at the rotatable connection point E. The cushion 33 is connected to the cushion support 17 . There is also an optional cushion support member 15, which is rotatably connected to the cushion frame 17 at the rotatable connection point F, and is rotatably connected to the second upper section 7-2 at the rotatable connection point G. The other end of the cushion support member 15 opposite to the connection of the cushion support 17 may include a footrest 36 . The cushion support member 15 is not essential and may be omitted. During this kind of design, the cushion 33 is just only connected with the end point (E end point) of the lower cross support member 3.

When the folding bicycle 100 is in use, the fixed structure 20 locks the rotatable connection point B-1, and fixes the first upper section 7-1 and the second upper section 7-2 together, so that the connection AB-1 and the connection B-1C, etc. Effective in forming a connection AC, causing AC to be a fixed distance. Since AC is now a fixed length, and both AD and CD are also of fixed length, the triangle ACD is a stable structure. Because the angle ACD is fixed, its opposite angle ECG is also fixed, so that the quadrilateral CEFG supporting the seat cushion 33 and the footrest 36 is also stable. Folding bicycle 100 is safe and reliable driving.

In order to fold the folding bicycle 100, turn the locking member 24 to make the fixing structure 20 in a loose state, and lift the seat cushion 33 forward near the rotatable connection point E. The loosening of the fixing structure 20 makes the angle ACD no longer fixed, and AB-1 and B-1C are no longer limited to a fixed distance AC. The triangle ACD can be freely changed into the quadrilateral AB-1CD, and the quadrilateral CEFG can also be freely changed in shape. The quadrilateral AB-1CD and CEFG can be flattened and folded forward, as shown in Figure 2.

FIG. 3 shows the structure of the folding bicycle 100 when it is folded. The first wheel 35 can be in contact with the second wheel 37 . The angle AB-1C depends on the distance between the first wheel 35 and the second wheel 37 when the quadrilateral AB-1CD is at its smallest. As the quadrilateral CEFG is completely flattened, the folding bicycle 100 is in a fully folded state, the lower cross support member 3 and the cushion support member 15 can move closer to each other, and the seat cushion 33 is in a vertical state. The frame can also be locked in the folded state by the fixing structure 20, so the foldable bike 100 can be dragged or pushed away like a piece of luggage. When folded, the folding bike 100 can also be used as a walker, because the user can use the steering member 31 to support the weight of the body and play a stable role when walking forward.

A possible embodiment of the fixing structure 20 is shown in FIGS. 4-6 . The fixing structure 20 fixes the first upper section 7-1 and the second upper section 7-2 together at the rotatable connection point B-1. On the top of the end of the first upper section 7-1, there is a fixing member 22 perpendicular to the first upper section 7-1, which is close to the top of the second upper section 7-2, preventing the second upper section 7-2 from moving counterclockwise The rotation also prevents the first upper section 7-1 from rotating clockwise, so this member is called the blocking member 22. There is also a rotatable locking member 24 attached to the first upper section 7 - 1 at a distance from the blocking member 22 . When the locking member 24 rotates to the vertical direction with the first upper section 7-1, the fixed structure 20 is in the locked setting state. At this moment, the first upper section 7-1 cannot rotate counterclockwise, nor can the second upper section 7-2. Turn clockwise. The locking piece 24 is connected with the first upper section 7-1 through the rotatable connection point H. When the locking piece 24 turns to the vertical direction with the first upper section 7-1, see Fig. 4, the first section and the second section (7 -1, 7-2) cannot move relative to each other, and the fixed structure 20 is considered to be locked.

When the locking member 24 turns to the direction parallel to the first upper section 7-1, as shown in Fig. 5, the fixed structure 20 is in a loose setting or unlocked state, and the first upper section 7-1 can rotate counterclockwise while the second upper section 7 -2 can be rotated clockwise, as shown in Figure 6. This action allows folding bike 100 to fold forward, as seen in FIGS. 2 and 3 . When the first upper segment 7-1 is further rotated beyond the range shown in Figure 6, the locking member 24 can pass over the second upper segment 7-2, and the locking member 24 can turn to the direction perpendicular to the first upper segment 7-1 again, Lock the folded folding cart 100 and keep it in the folded state until it is unlocked again.

The fixing structure 20 can also be realized by means of a bolt 27, as shown in Fig. 6, when the bolt 27 is aligned with the hole passing through the first upper section 7-1 and the second upper section 7-2 and inserted, the two sections of components (7-1) can be locked. -1,7-2). After the bolt 27 is removed, the relative rotation of the first upper section 7-1 and the second upper section 7-2 can be allowed again.

Figure 7 shows a second embodiment of the folding cart 100-1. Many of the same features were described in detail in the previous embodiment. The main difference is that the folding bike 100-1 has a complete upper cross support member 7 instead of being divided into a first upper section and a second upper section connected at B-1. Another difference is that the lower cross bracing element 3 is composed of a first lower section 3-1 and a second lower section 3-2, which are connected at B-2. The two lower segments ( 3 - 1 , 3 - 2 ) can be fixed by the aforementioned locking structure 20 .

When the folding bike 100-1 is in use, the fixed structure 20 locks the rotatable connection point B-2 connecting the first lower section 3-1 and the second lower section 3-2, so that the connecting sections DB-2 and B-2C are equivalent The DC segment is formed in such a way that the DC segment becomes a fixed length. In addition, the AD segment and AC are originally fixed lengths, so the triangle ACD is a stable triangle structure. Because the angle ACD is a fixed angle, its opposite angle ECG is also fixed. The quadrilateral CEFG supporting the seat cushion 22 and the footrest 36 is also stable, or non-foldable. The folding cart 100-1 is safe and reliable to use.

When the folding bike 100-1 is folded, the locking member 24 is rotated, and the seat cushion 33 moves toward the rotatable connection point E, the fixed structure 20 causes the angle ACD to be no longer fixed, and DB-2 and B-2C are no longer a fixed distance DC . The triangle ACD is no longer limitedly transformed into the quadrilateral ACB-2D, and the quadrilateral CEFG can also change its shape accordingly. Quadrilaterals ACB-2D and CEFG can be folded forward.

Unless otherwise stated, any feature, aspect or element of any of these systems may be deleted, added to, combined with, or modified by any other feature, aspect or element of any of the systems. It will be apparent to those skilled in the art that modifications and adaptations may be made to the above-described systems and methods without departing from the spirit and scope of the invention, which is limited only by the claims.
