Detailed Description

As shown in fig. 1, a bicycle structure diagram includes a connecting beam 9, a seat cushion mounting tube 10, a seat cushion assembly, and a rear wheel 12 connected to a rear end of the connecting beam 9 through a rear fork connecting arm assembly 11, wherein a lower end of the seat cushion mounting tube 10 is fixedly connected to a top of a rear end of the connecting beam 9, and the seat cushion assembly includes a supporting rod 13 and a seat cushion 14 fixed to a top of the supporting rod 13; the support rod 13 is inserted into the top of the seat cushion mounting cylinder 10, and is fixed in a limiting manner by a cam hoop component (namely, a locking buckle with a cam wrench) which is fixed on the outer wall of the top of the seat cushion mounting cylinder 10 and is shown in fig. 2 (the component is already applied in a large area, such as a seat cushion height adjusting component on a shared bicycle); the biggest difference between the bicycle and the existing bicycle lies in that the driving mechanism and the steering mechanism are designed into a whole and are designed at the front wheel of the bicycle, namely, the traditional front fork assembly is improved, so that the front end of the connecting beam 9 is fixedly connected with the rear end of the shaft sleeve 5, and the shaft sleeve 5 is mainly fixed to achieve steering operation.

The steering and driving integrated mechanism is referred to as a driving steering mechanism in the embodiment, and includes a steering assembly, a joystick 1, a driving wheel 2, a ratchet wheel 3 (also called flywheel, generally mounted on a mounting shaft of a rear wheel of a vehicle for driving the rear wheel of the vehicle, which is the most improved point of the driving and steering integrated design), the steering assembly includes a front fork 4, a relatively fixed shaft sleeve 5 (fixedly mounted on a connecting beam 9 relative to the front fork 4, because the front fork 4 mainly serves to mount the front wheel and realize steering operation, which is the same as the traditional bicycle design and function), and a U-shaped coupling head 6, and the U-shaped coupling head 6 is a core component for realizing steering and driving integration.

As can be seen from FIG. 1, the connecting rod at the top of the front fork 4 passes through the axle sleeve 5 upwards and is fixedly connected with the bottom of the U-shaped connecting head 6 arranged above the axle sleeve 5, so that the front fork 4 can be driven to rotate relative to the axle sleeve 5 by operating the U-shaped connecting head 6, and the front wheel 7 of the vehicle is driven to turn.

The main operation components for realizing the integration of steering and driving are as follows:

the lower end of the control lever 1 is inserted into a U-shaped groove of a U-shaped coupling head 6, the lower end of the control lever 1 is connected with a rotating shaft 8 transversely penetrating through opposite side walls of the U-shaped groove, a driving wheel 2 is arranged at one end of the rotating shaft 8, the driving wheel 2 is arranged outside the U-shaped groove, the lower end of the control lever 1 is arranged in the U-shaped groove in a different mode, the rotating shaft 8 transversely penetrates through the U-shaped groove and the lower end of the control lever 1, the control lever 1 is connected with the U-shaped coupling head 6, the rotating shaft 8 is fixedly connected with the lower end of the control lever 1 and cannot rotate relative to the control lever 1, however, the rotating shaft 8 must rotate relative to the U-shaped coupling head 6, so that the driving wheel 2 which is arranged outside the U-shaped groove and fixed at one end of the rotating shaft 8 is driven to synchronously rotate forward and backward by a belt (the corresponding driving wheel is a belt wheel, and the outer ring-shaped groove on the The ratchet wheel 3 which is arranged below the bicycle 4 and is coaxial with the bicycle front wheel 7 rotates forwards and backwards, so that the bicycle front wheel 7 is driven to rotate (the principle and the installation mode of driving the bicycle front wheel by the ratchet wheel are the same as those of the existing bicycle, only the mode of driving the rear wheel in front is changed into the mode of driving the front wheel, and the bicycle rear wheel and the ratchet wheel which is coaxially arranged with the bicycle rear wheel are installed in front of the bicycle provided by the embodiment and are used as the bicycle front wheel).

For the convenience of storage, the operating rod 1 provided in this embodiment suggests the currently ubiquitous telescopic rod assembled by at least two sleeves, so that the length of the operating rod can be changed, and of course, the telescopic rod with multiple length adjustment functions shown in fig. 3 can also be used.

Similarly, a telescopic beam similar to the structure of fig. 3 can be used as the connecting beam. Namely, the connecting beam 9 is formed by sleeving a front connecting pipe 15 and a rear connecting pipe 16; the rear end of the front connecting pipe 15 and the front end of the rear connecting pipe 16 are connected and limited through a limiting bolt.
