Two-wheeled vehicle leg
Technical field
The bracing or strutting arrangement that the present invention relates to the cart of a kind of bicycle, battery-driven car, motor bike etc., relates in particular to a kind of two-wheeled vehicle leg.
Background technology
Common two-wheeled vehicle leg is divided into single-leg type and two leg formulas, and single-leg type car leg is installed on rear axle, tilting of car body when it supports, and poor stability, is now eliminated by market gradually.In existing vehicle, the ratio of battery-driven car is increasing, battery-driven car is due to from great, easily damaged, therefore adopt two leg formula car legs of good stability, it comprises car body connection bracket, supporting leg, and supporting leg is arranged in car body connection bracket, and car body connection bracket is arranged on two-wheel car, this kind of two-wheeled vehicle leg wants motorist firmly to lift car, by the common support of two car legs, just car can be propped up, car is steadily stood; When supporting, the car leg of this form comparatively requires great effort, operating difficulties for women, old man.
Summary of the invention
The two-wheeled vehicle leg that the object of this invention is to provide a kind of support labor-saving.
For achieving the above object, the technical solution used in the present invention is as follows: a kind of two-wheeled vehicle leg, comprise matrix and two supporting legs, and two supporting legs are connected on matrix, and matrix is fixedly connected on vehicle frame, it is characterized in that:
Above matrix, there is connecting device, matrix is provided with axle and axle sleeve, left branch leg and right supporting leg are installed on the two ends of axle, on matrix and one of them supporting leg, reset catch gear is installed, on axle, have and keep the Bringing-back mechanism of two supporting legs in same plane, left branch leg and right supporting leg supporting leg are telescopic leg.
Wherein, the connecting device of described matrix is two bolts that are connected on matrix.
Wherein, described reset catch gear comprises slide rail, extension spring, stretcher, slide block, slide rail is fixed on one end of matrix, slide rail is a middle thin plate with rectangular indentation, on slide rail, there is a slide block that can slide along slide rail, slide block is with annulus, and one end of extension spring is connected with annulus, and the other end is connected with stretcher.
Wherein, described Bringing-back mechanism includes torsion spring, torsion spring catch, and two torsion spring catch are arranged on respectively left branch leg and right supporting leg, has two draw-in grooves on two torsion spring catch, two torsion spring catch are positioned at the centre at torsion spring two ends, and the two ends of torsion spring are stuck in above draw-in groove.
Wherein, described left branch leg is connected with left leg by spring, and right supporting leg is connected with right leg by spring.
By such scheme and using method, can find out that the present invention uses comparatively simple structure just to complete effortlessly the support of car body, whole process is without promoting car body, and not only easy and simple to handle but also very laborsaving, women old man can easily support.

The specific embodiment
As shown in Figure 1 and Figure 2, a kind of two-wheeled vehicle leg, it comprises matrix 6, supporting leg, matrix 6 is fixedly connected on vehicle frame, and supporting leg and matrix 6 are rotationally connected, and supporting leg is two: left branch leg 2, right supporting leg 13, they lay respectively at the both sides of car body, on a supporting leg, reset catch gear is installed therein, matrix 6 is the support being connected with car body, and matrix 6 is fixed and is connected with car body by bolt 4.
On matrix 6 sidewalls, axle 5 is housed, left branch leg 2 is with right supporting leg 13 both sides that "eight" shape is connected to axle 5, between two supporting legs, by flexible restoring organ, remains on same plane.
Bringing-back mechanism includes torsion spring 7, torsion spring catch 10, two torsion spring catch 10 are arranged on respectively left branch leg 2 and right supporting leg 13, on two torsion spring catch 10, have two draw-in grooves, two torsion spring catch 10 are positioned at the centre at torsion spring 7 two ends, and the two ends of torsion spring 7 are stuck in above draw-in groove.Bringing-back mechanism guarantees that two supporting legs are positioned at same plane all the time.
Matrix 6 of the present invention welds axle sleeve 3 above, and axle sleeve 3 can carry out spacing.Axle sleeve 3 is the thin plate of cross section circular arc, is used for to two supporting legs rotation to carry out spacingly, makes left branch leg 2 and right supporting leg 13 can only rotate about 90 degree.As shown in Figure 3, the axle sleeve 3 that is welded on matrix 6 inwalls is by the spacing position that (the place ahead of car body) tilts slightly left of supporting leg vertical direction.Supporting leg become with matrix angle and the gravity of car body self reach locking effect.
Left branch leg 2, right supporting leg 13 are elastic telescopic supporting leg, and left branch leg 2 is connected with left leg 1 by spring, and right supporting leg 13 is connected with right leg 14 by spring, and telescopic leg is being overlapped inner telescoping tube by the spring in sleeve pipe.
As shown in Figure 3, described reset catch gear comprises slide rail 9, extension spring 11, stretcher 12, slide block 15, slide rail 9 is fixed on the right-hand member of axle 5, stretcher 12 is directly welded on supporting leg, slide rail 9 is a middle thin plate with rectangular indentation, has a slide block 15 that can slide along slide rail 9 on slide rail 9, and slide block 15 is with annulus, one end of extension spring 11 is connected with annulus, and the other end is connected with stretcher 12.
During use, user first tilts car body to heteropleural, makes the leg of own side unsettled, then stretcher 12 is dialled backward, auxiliary with manpower and under the effect of extension spring 11, after own side leg, turns.Under extension spring 11 effects, after stretcher 12, turn, slide block 15 slides to upper right side.Extension spring 11 is spacing in horizontality by supporting leg.It as shown in Fig. 3 solid line and dotted line, is exactly the view before supporting leg rotates backward and after rotating.Then car body is rolled tiltedly to oneself, now rear wheel lands, and under the effect of torsion spring 7, heteropleural leg rotates backward; It is now driving states.
If want, car is propped up, first car body is tilted to heteropleural, with pin, the stretcher 12 that is positioned at oneself side is forwards pulled, extension spring 11 drives one's own side's leg and heteropleural leg to rotate forward, when own side leg arrives Support Position and keep this position under extension spring 11 effects, heteropleural leg is owing to hindering and not yet arriving Support Position with ground, then to own inclination, tiltedly makes the trailing wheel heteropleural leg that lands unsettled car body, under the effect of torsion spring 7, heteropleural leg arrives Support Position, and leg enters holding state.
