[specific embodiment]

The utility model is further described with reference to the accompanying drawing:

As shown in Figures 1 to 5, a kind of stroller can be moved to folding position from expanded position after locking device unlock Set, including symmetrically arranged two groups of bottom supports 1, the front and rear sides of the bottom support 1 be respectively equipped with front-wheel 1a and Rear-wheel 1b, every group of 1 front end of bottom support are rotatably connected to hound 2, are rotatably connected to handspike 3 on the hound 2, Be equipped with the rear pole 4 that be rotatablely connected with the two between 3 lower end of handspike and bottom support 1, the hound 2 and The position that is hinged of handspike 3 is located at rear pole 4 and handspike 3 is hinged the top of position, the rear pole 4, handspike 3, Hound 2 and bottom support 1 constitute four-bar mechanism.Stroller is when folding, then pushing hands forward after locking device unlock Push rod 3 simultaneously applies downward pressure to handspike 3, the rotation of 2 lower end opposing floor portion supporting element 1 of hound, 4 lower end of rear pole also phase Bottom support 1 is rotated, bottom is drawn close close to 1 front end of bottom support, hound 2 and 4 upper end of rear pole in 3 upper end of handspike 1 rear end of portion's supporting element.Entire folding process, simple and quick, folding is smooth, and volume after folding is small, easy to carry.Baby pushes away The locking device of vehicle can use the locking mechanism of conventional pushchair, such as the bolt that can be slided is arranged in handspike 3, and The slot that can be engaged or be detached from bolt is set on hound 2.

As shown in Figures 2 and 3, the rear pole 4 is L shape, and the rear pole 4 includes stull section 41 and opposite stull The integrated bending forming of section 41 and length are greater than the diagonal brace section 42 of stull section 41, and the stull section 41 and the rotation of handspike 3 connect It connects, the diagonal brace section 42 and bottom support 1 are rotatablely connected.Therefore, stroller folds smooth in folding process, folds Flexibly, situation appearance is avoided interference with.

As shown in Figure 1 to Figure 3, the stroller further includes seat support, the seat support include with The rotation seat 51 that rear pole 4 is rotatablely connected, the rotation seat 51 is interior to be equipped with the mounting bar 52 that can be slided in it, the seat 52 front end of hack lever and hound 2 are rotatablely connected.When baby stroller folds, 52 front end of mounting bar is rotated relative to hound 2, and And mounting bar 52 slides in rotation seat 51, to realize that seat support follows entire vehicle frame folding, operates very convenient Fast.

As shown in Figure 1, Figure 2, shown in Fig. 6 and Fig. 7, the stroller further includes for rolling over it laterally in the lateral direction Folded laterally folded component, the laterally folded component include lower cross portion and upper cross portion, the lower cross part Part includes the first crossbar 61 and the second crossbar 62 for intersecting and being rotatablely connected, first crossbar 61 and second The front end of crossbar 62 is rotatablely connected with corresponding 1 front end of bottom support respectively, and first crossbar 61 and second is handed over The rear end of fork arm 62 respectively be set on two groups of bottom supports 1 and can connect along the rotation of sliding sleeve 65 that bottom support 1 slides It connects, the back link 66 hinged with the two is additionally provided between the sliding sleeve 65 and rear pole 4；The upper cross members include phase The third crossbar 63 and the 4th crossbar 64 for mutually intersecting and being rotatablely connected, the third crossbar 63 and the 4th crossbar 64 Lower end be rotatablely connected respectively with corresponding 1 front end of bottom support, the third crossbar 63 and the 4th crossbar 64 Upper end is rotatablely connected with corresponding rear pole 4 respectively.In baby stroller unfolded state, the first crossbar 61 intersects with second The angle of bar 62 is larger, and when baby stroller folds, the rear pole 4 of rotation pushes back link 66, and 66 lower end of back link just pushes away Dynamic sliding sleeve 65 slides backward along bottom support 1, and sliding sleeve 65 just pulls the first crossbar 61 and second to hand over during sliding The rear end of fork arm 62, so that the first crossbar 61 and the second crossbar 62 mutually rotation and mutual angle becomes smaller, therefore two Group bottom support 1 is drawn close in the lateral direction to narrow, so that third crossbar 303 and the 4th crossbar 304 are also opposite respectively Bottom support 1 and rear pole 4 rotate, so that the angle between third crossbar 303 and the 4th crossbar 304 also becomes smaller, because This, entire stroller vehicle frame is horizontally folded, and folding volume is further decreased, easy to carry.

As shown in Figures 1 to 4, the third crossbar 63 is coaxial hinged with corresponding rotation seat 51 and rear pole 4, 4th crossbar 64 is coaxial hinged with corresponding rotation seat 51 and rear pole 4, so that stroller folds smooth, receipts It closes flexible.

As shown in Figures 1 to 4, the bottom support 1 includes chassis bar 11 and the front-wheel that 11 front end of chassis bar is arranged The front end of frame 12, first crossbar 61 and the second crossbar 62 is rotatablely connected with corresponding 11 front end of chassis bar respectively, The lower end of the third crossbar 63 and the 4th crossbar 64 is rotatablely connected with corresponding 12 upper end of front wheel carrier respectively, described Front-wheel 1a setting is arranged in 12 lower end of front wheel carrier, the rear-wheel 1b in 11 rear end of chassis bar.Therefore, the whole knot of stroller Structure is simple and compact, and when folding folds flexibly.

As shown in Figure 1, Figure 2, shown in Fig. 6 and Fig. 7, the stroller further includes backrest module, the backrest module packet The back support bar 75 of two with the rotation connection of corresponding rotation seat 51 are included, is equipped between two back support bars 75 and is intersected and rotate The first backrest connecting rod 71 and the second backrest connecting rod 72 of connection, 72 lower end of the first backrest connecting rod 71 and the second backrest connecting rod It is hinged with corresponding back support bar 75 respectively, it 71 upper end of the first backrest connecting rod and is wherein equipped between a back support bar 75 With the third backrest connecting rod 73 of the two rotation connection, set between 72 upper end of the second backrest connecting rod and another back support bar 75 There is the 4th backrest connecting rod 74 with the two rotation connection.Back support bar 75 can relatively rotate the rotation of seat 51 and rotate folding forward, At the same time, the first backrest connecting rod 71, the second backrest connecting rod 72, third backrest connecting rod 73 and the 4th backrest connecting rod 74 can make two Root back support bar 75 is drawn close in the transverse direction of left and right and is folded, so that stroller also meets transverse direction while with backrest function The demand of folding.

As shown in Fig. 1, Fig. 6 and Fig. 7,3 upper end of handspike is additionally provided with hand-pushing handle 8, and the hand-pushing handle 8 includes point Not with the left handle 81 and right handle 82 of the rotation connection of corresponding handspike 3, and the left handle 81 and 82 turns of right handle Dynamic connection.The setting of hand-pushing handle 8, which can be convenient user, pushes perambulator walking, and when stroller folds, left handle 81 It is mutually rotated with right handle 82, and left handle 81 and right handle 82 are rotated relative to handspike 3 again, two handspikes 3 are also mutual It draws close, makes entire stroller that there is the case where hand-pushing handle 8 to be also able to satisfy in transverse direction folding.
