Abstract

A sift beam latch free foldable bicycle or electric vehicle frame is characterized in that the lower beam pipe and back wheel frame pipe for tension in a triangle frame pipe are changed into steel wire soft beams, the connection between the transverse beam pipe and the vertical beam pipe is changed into collapsible shaft connection, therefore, the frame after deformation can be fixed by the gravities of users and itself completely, and the utility model can deform by tension when free with the gravity of users. The utility model has simple structure, stability, reliability, few auxiliaries, low weight, small volume after deformation, simple manufacture technology and low cost.

Description

Soft beam does not have lock pin folding bicycle or electromobile frame

Affiliated technical field

The utility model relates to the bicycle frame device of folding bicycle or electric motor bicycle with folding.

Background technology

Present folding bicycle and electromobile frame, basically be distortion such as the turnover that utilizes hard materials such as arm, rod, support plate to carry out, flexible, rotation, auxiliary members such as its lock pin, folding shaft are many, and the comparatively simple volume of structure is bigger, and the volume small construction becomes complicated.

Summary of the invention

Folded bicycle is simple more in order to allow, volume is less, the utility model provides soft beam of a kind of steel rope and folding shaft device, can rely on the gravity of human body and car body to make the distortion vehicle frame fix fully, it is fast, simple in structure that this soft beam does not have the distortion of lock pin vehicle frame, and distortion aftercarriage volume is less.

The technical scheme that its technical matters that solves the utility model adopts is:

1. the underbeam with the car body triangular beam changes the soft beam of steel rope into, the thickness pulling force of steel rope is advisable at 500kg to 2000kg, certainly also choice refreshments or thick point again, the front end of one end and crossbeam pipe is connected and fixed, method of attachment utilizes the only head of double joint steel rope double joint to fix by the method for knockout on the beam, there is not auxiliary member the simplest, certainly also can utilize auxiliary member to be connected and fixed, end is connected and fixed with the lower end and the axis axle leather hose of upright beam in addition, method of attachment remains the mode that knockout passes through on the beam of utilizing, in order to reinforce fixed effect, can adopt many methods to utilize the steel rope other strength fixation of turning round, also can utilize auxiliary member to be connected and fixed certainly; And the rear end of crossbeam pipe will be connected in the mode of folding shaft with the upper end of upright beam pipe, because it is relatively good that steel rope can play deformation performance when not having pulling force, thereby make that constituting triangle frame thus possesses changeability, can deal with problems for one, simple in structure, rely on the method for human body gravity fixed deformation vehicle frame reliable for effect ingenious.

2. simpler in order to allow the soft beam of steel rope and the lower end of upright beam pipe be connected effect, firmly, to found the beam pipe, the rear wheel support pipe, it then is necessary that trombone slide in the middle of the spider that trailing wheel lower end trombone slide is constituted changes the disjunctor steel rope into, not only save weld nugget and vehicle frame weight, and the soft beam of steel rope becomes the one connection before and after making, fixed effect is stronger, structure is simpler, the method of attachment of steel rope straining beam and rear wheel support pipe lower end and trailing wheel adapter plate still utilizes many other strength methods of turning round to fix, no auxiliaring piece structure is simple, can certainly utilize auxiliary member to connect.

3. in order to adapt with the more simple folding stand of structure, it is upright the intensity of pipe, high seatpillar to improve the steamboat overall height simultaneously, it is comparatively suitable to adopt male and female sleeve pipe plug to connect mode of texturing, male and female sleeve pipe plug gap is suitable, relies on the locking of jackscrew or Fast detachable unit, and public plug is with after female separates, the dependence connection chain connects, connection chain is as omnipotent folding shaft, and the recipient is not to the restriction of, position, and is simple in structure.

4. weld the holding capacity that " n " shaped steel plate improves front fork tube below vertical tube of front fork and between the breeches pipe of the left and right sides for the safety performance that improves front fork tube.

The beneficial effects of the utility model are: change tension beam into steel rope soft beam, rely on human body gravity that vehicle frame is fixed by folding shaft, simple in structure, stability is reliable, auxiliary member is few, car body is in light weight, distortion back volume is little, the simple cost of manufacture craft reduces.
