Detailed description of the invention
below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is further elaborated.
all this children trolley to be installed in use about the definition of direction below, on children trolley, viewed direction defines children's sitting, the left and right directions shown in fore-and-aft direction that is Fig. 2, Fig. 4, 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. 1～4, comprise have deployed condition and folded state go-cart vehicle frame, be located at front portion at the bottom of go-cart vehicle frame front-wheel 10, be located at rear portion at the bottom of go-cart vehicle frame trailing wheel 20, 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, fork 5 and rear pole 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.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 by the first axle 7, and the first axle 7 is positioned at below front frame 2 and push rod 1, after poppet 3 transit points on front frame 2.One end of fork 5 connects on present bar 4 rotationally by the second axle 8, and the other end of fork 5 is connected on after poppet 3 rotationally.Under go-cart vehicle frame deployed condition, fork 5 is positioned at the below of a bar 4, and a bar 4 support along the vertical direction can be provided so to a certain extent.
rear pole 6 is located between a bar 4 and push rod 1, and the top of rear pole 6 is connected on push rod 1 rotationally, and the bottom of rear pole 6 connects on present bar 4 or fork 5 rotationally, and the bottom of rear pole 6 connects on the rear portion of present bar 4 rotationally by the 3rd axle 9 herein.Wherein, the bearing of trend of the second axle 8 edge seat bars 4 is between the first axle 7 and the 3rd axle 9.
between after poppet 3 and fork 5, lockout mechanism is set both is locked, or lockout mechanism is set at after poppet 3 and seat between bar 4 both are locked, can make go-cart vehicle frame launch time in stable deployed condition.Certainly, lockout mechanism also can be set to other versions or be located at other positions, as long as ensure that go-cart vehicle frame interfixes between each rod member under deployed condition.
in use, go-cart vehicle frame is under deployed condition for the children trolley of the present embodiment, and as shown in Figure 1 and Figure 2, front frame 2, after poppet 3 and push rod 1 launch mutually, and seat bar 4 extends along fore-and-aft direction, and rear pole 6 supports between present bar 4 and push rod 1.In the time that needs fold this go-cart vehicle frame, first the locking of mechanism unlocks, then push rod 1 and seat bar 4 move downward under the effect of himself gravity, seat bar 4 moves downward around the second axle 8, drive fork 5 to rotate and move downward relative to after poppet 3, pivoted downward when wherein fork 5 rotates between rear pole 6 and fork 5.Seat bar 4 drives rear pole 6 to rotate and move downward around the 3rd axle 9 simultaneously, rear pole 6 drives push rod 1 to rotate and draw close to after poppet 3 gradually relative to after poppet 3, the front end of seat bar 4 also rotates and drives front frame 2 to draw close to after poppet 3 gradually around the first axle 7 simultaneously, final push rod 1, front frame 2, after poppet 3, seat bar 4, fork 5, rear pole 6 are drawn close mutually, and the go-cart after folding as shown in Figure 3, Figure 4.Go-cart vehicle frame after folding can stand on ground certainly, and is flats compact form, takes up room less, can be convenient to deposit and carry.The structure that gets final product release when lockout mechanism can be set to down pressing seat bar 4 rear portion, in the time of Folding trolley vehicle frame, directly can and fold the release of go-cart vehicle frame by wedge bar 4 rear portions like this, and folding operation is more convenient.
in the time that needs launch this go-cart vehicle frame, push rod 1 is upwards lifted, it is rotated relative to front frame 2 and after poppet 3, under the effect of rear pole 6, seat bar 4 and fork 5, front frame 2 expansion relative to after poppet 3, 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 compactness after folding, takes up room less, is easy to carry and deposits.
