Technical field

The utility model belongs to technical field of bicycles, more particularly to a kind of double electric double leval jib damping frames.

Background technique

Continuous improvement and bicycle of the bicycle as a kind of traditional traffic means of transport, with people's environmental consciousness Culture increased popularity and increasingly favored by people.Damping is the important finger of crossbeam cycling comfort level and performance Mark.The damping frame of existing bicycle includes front forked frame, Rear frame and damper, before front frame, damper and Rear frame are The damping frame front and back lateral dimension of laterally arrangement afterwards, such mode is limited, and structure is single, is unfavorable for the wound of bicycle structure Newly, swing angle is big in the damper course of work, and damping effect is bad.

Summary of the invention

The utility model aims to solve the problem that the bad technical problem of vehicle frame damping effect of bicycle in the prior art and provides A kind of structure novel, good damping effect, the long double electric double leval jib damping frames of course continuation mileage.

The utility model is adopted the technical scheme that solve technical problem present in well-known technique: a kind of double electricity four Connecting rod damping frame, including front frame, Rear frame and damper, it is characterised in that: the front frame by vertical tube of front fork, crossbeam and Saddle stand pipe is constituted, and the vertical tube of front fork is fixed on the front end of the crossbeam, after the saddle stand pipe is fixed on the crossbeam End, the inside of the crossbeam have two axial battery outer slots；The front of the Rear frame is located at the lower rear of the crossbeam, The front end of the Rear frame is hinged by the first pin shaft with the crossbeam；It further include double leval jib, the double leval jib is by bilateral symmetry And be made up of two 2 hinged connecting rods of the second pin shaft, the double leval jib is between the crossbeam and the Rear frame and is located at The rear of first pin shaft, the upper end of the double leval jib pass through the third pin shaft hingedly crossbeam, the lower end of the double leval jib By the hinged Rear frame of the 4th pin shaft, the front end of the damper is hinged by the 5th pin shaft with the crossbeam, described to subtract The rear end of shake device is hinged on second pin shaft.

The utility model can also use following technical measures:

The front lower portion of the Rear frame is fixed with Five-way tube.

The inside of the crossbeam has axial ribs body.

The vertical tube of front fork through the crossbeam front end and with the beam welding.

The rear end of the crossbeam is welded and fixed in the lower end of the saddle stand pipe.

On the double leval jib at the second pin shaft on rear side of angle be 60 ° -150 °.

The utility model has the advantages and positive effects of:

Front frame, damper and Rear frame are vertical distribution design in the utility model, and structure novel is compact, can reduce The overall dimensions of cycle frame, and be conducive to bicycle structure innovation.The swing of Rear frame can pass through in the utility model Double leval jib is converted into the linear movement of the second pin shaft, so that damper be enabled to play more preferably damping effect.

Dual power supply can be assembled in the present embodiment middle cross beam, dual power supply can respectively or one is all the electronic of electric bicycle Body provides power, can not only greatly increase the course continuation mileage of electric bicycle, promote power performance, and each of dual power supply Power supply can be removed individually and be charged, and electric bicycle will not be enabled to limit use because of charging, make electric vehicle can continuously With.In addition, not needing the additional household living space for specially storing reserve battery in the state that dual power supply charges, mention significantly The practical performance of high electric bicycle.
