Embodiment 1

As shown in figs. 1-11: a kind of foldable structure being applicable to rear described in the utility model, including grip switches 1, elbow 2, mounting 3, tailstock assembly the 4, first rotating shaft the 5, second rotating shaft the 6, the 3rd rotating shaft the 7, the 4th rotating shaft 8 and locating piece 10, grip switches 1 is rotationally connected with in the middle part of elbow 2, the front end of the rear end of elbow 2, the lower end of mounting 3 and tailstock assembly 4 is rotationally connected by first rotating shaft the 5, second rotating shaft the 6, the 3rd rotating shaft 7 and the 4th rotating shaft 8, and locating piece 10 is rotatably connected on the both sides of the 3rd rotating shaft 7 by bolt 101.

Further, the pointed projections 11 of grip switches 1 contacts connection with the first rotating shaft 5, and its effect is to make tailstock assembly 4 keep stable during riding, and prevents the tailstock assembly 4 from rotating counterclockwise around the second rotating shaft 6.

Further, the hook 24 of elbow 2 is articulated in the 4th rotating shaft 8.24 position-limiting actions of the hook of elbow 2, the angle preventing the tailstock assembly 4 from rotating counterclockwise is excessive.

Further, being additionally provided with spring 9 between described grip switches 1 and elbow 2, its effect is the rotation limiting grip switches 1.After rear is launched, make the pointed projections 11 of grip switches 1 without departing from the first rotating shaft 5, limit the first rotating shaft 5 and rotate along mounting hole position 21.

Further, described 4th rotating shaft 8 is rotationally connected by locating piece 10 and the 3rd rotating shaft 7.Locating piece 10 can be driven to rotate around the 3rd rotating shaft 7 when folding or opening rear, as it is shown in figure 9, locating piece 10 is in step-like, the center of rotation of locating piece 10 is eccentric in the second rotating shaft 6, under rider state, it is spacing to it that the high step 102 of locating piece 10 can withstand vehicle seat plate 32.When drawing in, along with turning clockwise of locating piece 10, vehicle seat plate 32 can depart from the high step 102 of locating piece 10 therewith, release position-limiting action, and vehicle seat plate 32 closes up along clockwise direction.

Described tailstock assembly 4 includes that battery case 41, tailstock left plate 42 and tailstock right panel 43, described tailstock left plate 42 are fixedly connected on left half-cell case 412, and tailstock right panel 43 is fixedly connected on right half-cell case 413.

As it is shown in figure 9, being shaped as of described locating piece 10 is step-like, its function is to 3 position-limiting actions of mounting.

Described battery case 41 includes battery box cover 411, left half-cell case 412 and right half-cell case 413, is provided with edge protuberance 414 on the downside of battery case 41, its function be by battery case 41 on the upside of spatial joint clearance reserved out, placement space is provided when drawing in for vehicle seat plate 32.

Described mounting 3 includes vehicle seat 31 and vehicle seat plate 32, and vehicle seat 31 is arranged on vehicle seat plate 32.

Described vehicle seat plate 32 is provided with rear handle 33, and its function is opening for rear.

As shown in Figure 10, described elbow 2 is provided with the 21, first position, hole, mounting hole position 22 and the second position, hole 23.First rotating shaft 5 is through mounting hole position 21, and the second rotating shaft 6 is through the first position, hole 22, and the 3rd rotating shaft passes the second position, hole 23, and there is position, corresponding hole the front end of battery case 41 and the lower end of mounting 3, in order to the first rotating shaft 5, the second rotating shaft 6, the 3rd rotating shaft 7 is passed through.The effect of mounting hole position 21 is: prevent elbow 2 from affecting the rotation of the first rotating shaft 5, and mounting hole position 21 is the movement locus of the first rotating shaft 5.

As shown in Figure 2: the operating principle that rear folds: with left hand, grip switches 1 being opened and upwards carried, grip switches 1 and the first rotating shaft 5 are in the state of leaving, and the rotation to tailstock assembly 4 does not play position-limiting action.Under gravity, tailstock assembly 4 is rotated clockwise around the second rotating shaft 6, and drives locating piece 10 to rotate around the 3rd rotating shaft 7 simultaneously.The effect of locating piece 10 is to 3 position-limiting actions of mounting, rotation the turning clockwise along with vehicle seat plate 32 of locating piece 10, in order to mounting 3 can be close together by assembly 4 with the tailstock.

The operating principle that rear is opened: grip switches 1 is opened and upwards carried with left hand, the right hand is held rear handle 33 and is upwards carried, vehicle seat plate 32 is made to rotate counterclockwise, mounting 3 drives the first rotating shaft 5 and tailstock assembly 4 to rotate the most counterclockwise, when rotating to final opening angle, tailstock assembly 4 drives locating piece 10 that vehicle seat plate 32 is played position-limiting action, unclamps grip switches 1, grip switches 1 all serves position-limiting action to the first rotating shaft 5 and tailstock assembly 4, and final car opens and fixes.

This utility model is not limited to above-mentioned embodiment, in the case of without departing substantially from flesh and blood of the present utility model, the thinkable any deformation of those skilled in the art, improves, replaces and each fall within protection domain of the present utility model.
