Embodiment

[0034] Example: such as Figure 1 to Figure 8 Show.

[0035] like image 3 As shown, the circular tube shell 3 is composed of a cylindrical tube connected with an upper cover and a lower bottom. The upper cover has a long strip hole 3-1, and the long direction of the long strip hole 3-1 coincides with the radial direction of the top cover. It is also consistent with the direction of the length of the vehicle; figure 2 As shown, the circular tube shell 3 has a pair of symmetrical radial gaps 3-2; the ball 43 is placed in the circular tube shell 3, and is connected to the inner circle of the circular tube shell 3, the lower plane of the upper cover of the circular tube shell 3, and the round tube The upper plane of the bottom of shell 3 is all made into rotation fit.

[0036] like figure 1 Shown, the front wheel 1 is a traditional bicycle wheel or an electric motor wheel, and the front wheel 1 is installed in the front fork 2; image 3 As shown, the upper end of the front ...

Abstract

Provided is a hand-and-foot double driving type no-chain bicycle. A cant beam, a rear slant fork and a horizontal rear fork are connected to form a triangular bicycle frame. The front end of the bicycle frame is fixed to a circular tube shell. The upper portion of a front bicycle fork, pedal frames and the lower portion of a connecting circular rod are connected with round balls through hinged shafts in the circular tube shell. The upper portion of the connecting circular rod is hinged to the lower portion of a push-pull tube provided with handles on the top portion. The push-pull tube and the connection circular tube not only can be combined to form a rigid push-pull rod, but also can relatively swing and rotate forwards and backwards, and the push-pull rod enables the front bicycle fork to twist a front wheel to veer. The pedal frame and the push-pull rod can be assembled to be a push-pull lever. A back wheel and a ratchet wheel are coaxially arranged in the horizontal rear fork. A sliding block is arranged on a sliding rod on the front portion of the horizontal rear fork. The front end and the rear end of a connecting rod are respectively hinged to the lower portion of the push-pull lever and the sliding block. The front end of an upper toothed plate and the front end of a lower toothed plate are hinged to the sliding block, and the toothed portion of the upper toothed plate and the toothed portion of the lower toothed plate clamp the ratchet wheel vertically. The upper toothed plate and the lower toothed plate are mutually attracted through magnets at intervals. The bicycle seat with a backrest is arranged on the top end of the triangular bicycle frame. Pedals and the hand push-pull lever drive the ratchet wheel to rotate and enable the bicycle to move forward through the connecting rod, the sliding block and the toothed plates.

Description

technical field [0001] The invention relates to the bicycle technology, in particular to a chainless bicycle with double drive of hands and feet. Background technique [0002] Existing bicycles of all kinds, large and small, are mostly driven by pedal sprockets, and only half a circle of pedals does work, so the driving force is not large. When encountering a ramp, the output of people is limited, and the speed of the vehicle is very slow. . Existing bicycles often suffer from unchained and stuck chain failures. In the existing rear-wheel drive bicycle, when a person rides, the upper body must lean forward or straighten, which is uncomfortable and prone to fatigue. Contents of the invention [0003] In order to overcome the above-mentioned defects of the existing bicycles, the present invention designs a chainless bicycle with double-drive hands and feet, which is comfortable to ride and not easy to fatigue, has fast acceleration and speed, is powerful when running on sl...
