The specific embodiment

below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is further elaborated.

below in the definition about direction, all to define according to children trolley user observes in use all around, above-below direction, left and right directions in left and right directions that is Fig. 1, left and right directions in fore-and-aft direction that is Fig. 2, wherein left is front, right-hand be after, above-below direction is the above-below direction in Fig. 1～5.

referring to the switchable children trolley shown in Fig. 1～5, there is folding vehicle frame, be located at front portion at the bottom of vehicle frame front-wheel 2, be located at the trailing wheel 3 at rear portion at the bottom of vehicle frame, vehicle frame comprise be positioned at both sides side stand 1, for connect both sides side stand coupling assembling, be located on vehicle frame for vehicle frame being locked in to the lockout mechanism (not shown) of deployed condition.

the side stand 1 of both sides includes front frame 11, pipe link 12, push rod 13, after poppet 14, seat bar 16, front-wheel 2 is installed on the bottom of front frame 11, trailing wheel 3 is installed on the bottom of after poppet 14, one end of pipe link 12 rotates and is connected with the top of front frame 11, its other end rotates and is connected with the bottom of push rod 13, the top of after poppet 14 is connected with a sliding part 15 rotationally, sliding part 15 is sliding sleeve herein, sliding sleeve is set on push rod 13 slidably, and push rod 13 is not only slidably but also rotatable relatively on the top that makes after poppet 14.The front portion of seat bar 16 rotates and is connected with front frame 11, and the rear portion of seat bar 16 rotates and is connected with after poppet 14.

coupling assembling comprise be located at vehicle frame rear portion rear pole assembly 4, be located at the bottom supporting rod assembly 5 of bottom of frame, rear pole assembly 4 can along the left and right directions folding of vehicle frame be located between the after poppet 14 of both sides with form to the spacing of vehicle frame left and right directions with support, bottom supporting rod assembly 5 adopts cross structure, it comprises mutual intersection and at two hinged foundation struts 51 of infall, the front portion of bottom supporting rod 51 is connected to the bottom of the front frame 11 of a side side stand rotationally, and its rear portion is rotated the end and is connected on the bottom of after poppet 14 of opposite side side stand 1.Coupling assembling also comprises that be connected between both sides front frame 11 can be along the cross bar 6 of vehicle frame left and right directions folding, and be connected to can be along the connecting rod 7 of vehicle frame left and right directions folding between both sides push rod 13 tops.

shown in each accompanying drawing, in the present embodiment, connection for convenience of each parts also makes vehicle frame integral structure more succinct simultaneously, on the same side side stand 1, seat the front portion of bar 16, the bottom of the top of front frame 11 and pipe link 12 by the first rotating shaft, rotate and be connected in same place, the seat rear portion of bar 16 is, the rear portion of the bottom of after poppet 14 and wherein a foundation strut 51 is rotationally connected mutually by the second rotating shaft, and the axial line of the first rotating shaft, the second rotating shaft is arranged in parallel.

this vehicle frame at least has two mode of operations upon deployment, and when vehicle frame is during in the first mode of operation, the top of the push rod 13 of both sides is positioned at the rear side of vehicle frame, and go-cart is forward and carries out use state, as shown in Figure 1 and Figure 2 state; When vehicle frame is during in the second mode of operation, the top of the push rod 13 of both sides is positioned at the front side of vehicle frame, and go-cart is reverse push enforcement state, as shown in Figure 3, Figure 4 state.Lockout mechanism at least has two latched positions, respectively the first mode of operation and second mode of operation of corresponding vehicle frame.

under general status, the top of push rod 13 be positioned at vehicle frame rear side and in as Fig. 1, forward shown in 2 is carried out state, when needs commutation is carried out, the locking of mechanism first unlocks, then push rod 13 is turned over forward together with pipe link 12, push rod 13 and pipe link 12 are relative to fixing and rotate with the transit point A of front frame 11 around pipe link 12, by the drive of sliding sleeve 15, after poppet 14 turns over before with push rod 13 and rotates forward, sliding sleeve 15 is along push rod 13 down slidings simultaneously, when the top of push rod 13 is positioned at the front side of vehicle frame, after poppet 14 also turns to a correct position, lockout mechanism locking, vehicle frame is in as Fig. 3, reverse implementation state shown in Fig. 4.

when needs fold this children trolley, go-cart is in the first mode of operation, the locking of mechanism first unlocks, make the transit point A between pipe link 12 and front frame 11, transit point B between push rod 13 and pipe link 12 is all in active state, first turn over forward push rod 13, push rod 13 overturns forward together with the pipe link 12 contact A that first rotates, simultaneously seat stressed its front portion of the bar 16 contact A that rotates overturns downwards, A point vertically moves down, under the effect of present bar 16, the top of the front frame 11 contact A that rotates overturns downwards, the bottom of front frame 11 is moved forward gradually, two bottom supporting rods 51 of bottom supporting rod assembly 5 are drawn close and extend along the fore-and-aft direction of vehicle frame along left and right directions, rear pole assembly 4 draws in gradually along left and right directions, then push rod 13 and the pipe link 12 contact B that rotates relatively rotates, pipe link 12 is turned over, bottom supporting rod assembly 5 continues to draw in rear pole assembly 4, reach is continued in the bottom of front frame 11, until front frame 11, push rod 13, after poppet 14, a seat bar 16 are drawn close mutually, this go-cart has folded, folding after state as shown in Figure 5.

when needs launch this go-cart from folded state, first upwards carried the top of push rod 13, the push rod 13 contact B that rotates rotates, when push rod 13 is raised to certain position, push rod 13 rotates together with the pipe link 12 contact A that rotates, then push rod 13 is turned over, transit point A rises, the front portion of seat bar 16 is lifted, under the effect of present bar 16 and bottom supporting rod assembly 5, move backward the front portion of front frame 11, and bottom supporting rod assembly 5 launches respectively and realizes before and after vehicle frame with rear pole assembly 4, the expansion of left and right directions, when go-cart vehicle frame is expanded to the first mode of operation, lockout mechanism locking, go-cart is stably in deployed condition.

to sum up, switchable children trolley of the present invention, it is simple in structure, and rod member is less, can realize easily the commutation of push rod 13 and use, and meanwhile, it is folding all very convenient with expansion, and the cart structure after folding is compact, takes up room little, can be convenient for carrying and store.
