The specific embodiment
below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is further elaborated.
definition about direction is all this children trolley to be installed in use below, on children trolley, viewed direction defines children's sitting, the left and right directions shown in fore-and-aft direction that is Fig. 1 to Fig. 3, and wherein left is front, right-hand be after, the above-below direction in above-below direction that is each accompanying drawing.
referring to the children trolley shown in Fig. 1 to Fig. 3, comprise have deployed condition and folded state go-cart vehicle frame, be located at go-cart bottom of frame wheel assembly, be located on go-cart vehicle frame for go-cart vehicle frame being locked in to the lockout mechanism (not shown) of deployed condition.This go-cart vehicle frame comprises push rod 1, front frame 2, after poppet 3, seat bar 4, the first fork 5 and the second fork 6.
the bottom of push rod 1 rotates and is connected with the top of front frame 2, the top of after poppet 3 is connected at least one parts in push rod 1 and front frame 2 rotationally, in the present embodiment, the top of the bottom of push rod 1, front frame 2 and the top of after poppet 3 link together rotationally.Wheel assembly comprises front-wheel 10 and trailing wheel 20, and front-wheel 10 is arranged on the bottom of front frame 2, and trailing wheel 20 is installed on the bottom of after poppet 3.
the front portion of seat bar 4 is connected on front frame 2 rotationally, and this transit point is below transit point between front frame 2 and push rod 1, after poppet 3.The middle part of the first fork 5 is connected on after poppet 3 rotationally, and one end of the first fork 5 connects on present bar 4 rotationally, and its other end rotates and is connected with one end of the second fork 6, and the other end of the second fork 6 is connected on push rod 1 rotationally.
in the present embodiment, the first fork 5 arranges and is L-type, it comprises the first bar portion 51 and the second bar portion 52 that is fixedly connected or is wholely set, the first bar portion 51 connects on present bar 4 rotationally by the first axle 7, the second bar portion 52 is connected on after poppet 3 rotationally by the second axle 8, and the outer end of the second bar portion 52 rotates and is connected with the second fork 6, when go-cart vehicle frame is during in deployed condition, the second axle 8 is positioned at the top of the first axle 7, and the first bar portion 51 is parallel to each other with seat bar 4.This is mainly according under go-cart vehicle frame deployed condition, definite for making to be positioned at suitable position between each rod member.Certainly, this first fork 5 also can be made as straight-bar, makes it with a seat bar 4, with after poppet 3, be positioned at same straight line with the transit point of the second fork 6.
in the present embodiment, lockout mechanism is to be located at the locking piece (not shown) for both are locked between a bar 4 and the first fork 5, and when go-cart vehicle frame launches, above-mentioned locking piece locking just can make go-cart vehicle frame under stable deployed condition.Certainly, lockout mechanism also can be set to other versions or be located at other positions, as long as guarantee that go-cart vehicle frame interfixes between each rod member under deployed condition.
in use, go-cart vehicle frame is in deployed condition, as shown in Figure 1 for the children trolley of the present embodiment, front frame 2, after poppet 3 and push rod 1 launch mutually, seat bar 4 extends along fore-and-aft direction, and lockout mechanism locking, between the first fork 5 and the second fork 6 fixing present bar 4, after poppet 3 and push rod 1.Between push rod 1, after poppet 3, the first fork 5 and the second fork 6, form four-bar linkage, between front frame 2, seat bar 4, the first fork 5 and after poppet 3, form another four-bar linkage.
when needs fold this go-cart vehicle frame, as shown in Figure 2, first the locking of mechanism unlocks, push rod 1 rotates towards the direction of after poppet 3, drive the second fork 6 and the first fork 5 to move downward, the first fork 5 drives the rear portion upward movement of seat bar 4 simultaneously, and meanwhile, the front portion of seat bar 4 is rotated and drives front frame 2 towards after poppet 3, to draw in gradually relative to front frame 2.Final push rod 1, front frame 2, after poppet 3, seat bar 4 and the first fork 5, the second fork 6 draw in mutually, and the go-cart after folding as shown in Figure 3.Go-cart after folding can be stood on ground certainly, and is flats compact form, takes up room less, can be convenient to deposit and carry.The rear portion that lockout mechanism can be set to carry a bar 4 is the structure of release just, and when Folding trolley vehicle frame, the rear portion that directly lifts a bar 4 just can make the release of go-cart vehicle frame and fold like this, and folding operation is more convenient.
when needs launch this go-cart vehicle frame, push rod 1 is upwards lifted it is rotated relative to after poppet 3, under the drive of the second fork 6, the first fork 5 and seat bar 4, between front frame 2 and after poppet 3, mutually rotate and launch along fore-and-aft direction, lockout mechanism locking, this go-cart is just under stable deployed condition.
?
to sum up, children trolley of the present invention, it is simple in structure, rod member negligible amounts, folding all very convenient with expansion operation, the cart structure after folding is compact, takes up room less, is easy to carry and deposits.
?
