Detailed description of the invention
below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is further elaborated.
in definition about direction, be all according to this children trolley in use below, all around, upper and lower that children's sitting is observed in go-cart always define.
referring to the children trolley shown in Fig. 1～6, comprise have deployed condition and folded state go-cart vehicle frame, be located at the wheel assembly of this go-cart bottom of frame, for go-cart vehicle frame being locked in to the lockout mechanism (not shown) under deployed condition.Go-cart vehicle frame comprises the side stand that lays respectively at the left and right sides, and the side stand of each side includes push rod 1, front frame 2, after poppet 3 and seat bar assembly.Wheel assembly comprises the front-wheel 20 that is arranged on front frame 2 bottoms and the trailing wheel 30 that is arranged on after poppet 3 bottoms.
the top of after poppet 3 is connected on push rod 1 rotationally, the bottom of push rod 1 along the length bearing of trend relative sliding of front frame 2 be located on front frame 2.Herein, the bottom of push rod 1 is fixedly provided with sliding part, and this sliding part can adopt the sliding sleeve 5 in the present embodiment, and sliding sleeve 5 is set on front frame 2 slidably along the length bearing of trend of front frame 2.
seat bar assembly is located between front frame 2 and after poppet 3, seat bar assembly can be made as the seat post 4 that a length is extended along fore-and-aft direction according to the mode of the present embodiment, be connected on after poppet 3 to the posterior rotation of this seat post 4, the front portion of seat post 4 is connected to the top of front frame 2 rotationally by turning cylinder 9, this turning cylinder 9 on front frame 2, be positioned at sliding sleeve 5 above.
seat bar assembly also can be set to following structure: a seat bar assembly comprises one end rotate the first bar and the second bar (not shown) that connect, the other end of the first bar is connected on front frame 2 by pivotally, the other end of the second bar is connected on after poppet 3 by pivotally, and seat bar assembly himself also can the folding by the mutual rotation of the first bar and the second bar in the time that go-cart vehicle frame is folding along fore-and-aft direction gathering like this.
lockout mechanism can be located between sliding sleeve 5 and front frame 2 for mutually locking between sliding sleeve 5 and front frame 2, the version that this lockout mechanism can adopt common lockhole to match with lock pin, on front frame 2, lock pin is set, on sliding sleeve 5, offer lockhole, lock pin can penetrate accordingly lockhole and locks or depart from lockhole and release.In the present embodiment, between the seat post 4 of both sides, be provided with the release carry hand (not shown) to above-mentioned lockout mechanism release, to between release carry hand and lock pin, couple together by trailing cable, can make like this user in the time lifting release carry hand, just can realize by trailing cable band pendulum lock pin separating lock hole the release of lockout mechanism.
certainly, in said structure, sliding sleeve 5 also can be located at the top of front frame 2 regularly, this sliding sleeve is set on push rod 1 slidably along the length bearing of trend of push rod 1, correspondingly, lockout mechanism is located between sliding sleeve and push rod 1 for by locking mutually between sliding sleeve 5 and push rod 1, so also can reach the technique effect that the present embodiment is identical.
described in each accompanying drawing, this go-cart vehicle frame also comprises that be connected between the side stand of both sides can be along the folding strut assembly with launching of the left and right directions of go-cart vehicle frame, and this strut assembly comprises bottom supporting rod assembly 6 and rear pole assembly 7.Wherein bottom supporting rod assembly 6 comprise mutual intersection and infall rotate connect bottom supporting rod 61, every foundation strut 61 all arranges in the following manner: the bottom that is connected to the posterior rotation of bottom supporting rod 61 after poppet 3, the front portion of bottom supporting rod 61 is connected to rotationally by attaching parts 10 on the front portion of seat post 4, and this attaching parts 10 is positioned at the front of turning cylinder 9 in seat post 4.Rear pole assembly 7 can along the left and right directions folding of go-cart vehicle frame be located between the after poppet 3 of both sides, shown in each accompanying drawing, this rear pole assembly 7 is the common structure in this area, repeats no more herein.
shown in each accompanying drawing, this go-cart vehicle frame also comprises the tread plate 8 of being located between both sides front frame 2 bottoms, this tread plate 8 can along the left and right directions folding of go-cart vehicle frame be located between the front frame 2 of both sides.
when this go-cart vehicle frame launches, shown in Fig. 1, Fig. 2, the sliding sleeve 5 of the bottom of push rod 1 slides into the top of front frame 2, lockout mechanism locking, front frame 2 is fixed with push rod 2 and is roughly extended along same length direction, seat post 4 is supported between front frame 2 and after poppet 3, between seat post 4, push rod 1 and after poppet 3, forms stable triangular structure.Bottom supporting rod assembly 6 along left and right and fore-and-aft direction be supported between the seat post 4 and after poppet 3 of both sides, rear pole assembly 7 launches to be supported between the after poppet 3 of both sides.
when needs are during by go-cart vehicle frame folding, carry release carry hand, shown in Fig. 3, Fig. 4, lockout mechanism is release just, the front portion of seat post 4 is raised and upward movement, drive the top upward movement of front frame 2, relative push rod 1 upward sliding of front frame 2, sliding sleeve 5 is gradually to the slid underneath of front frame 2; Seat post 4 is rotated relative to front frame 2 simultaneously, drives after poppet 3 to draw close to front frame 2 gradually; The anterior upward movement of bottom supporting rod 61, drives and mutually rotates between two foundation struts 61 and draw in along left and right directions, between rear pole assembly 7, synchronously draws in along left and right directions.The final state forming as shown in Figure 5, Figure 6, draws close between push rod 1, front frame 2, after poppet 3, seat post 4, bottom supporting rod assembly 6 and rear pole assembly 7 mutually, the compact conformation after folding, and can rely on front-wheel 20 and trailing wheel 30 certainly to stand on ground.
in the time that needs launch this go-cart vehicle frame, upwards pull push rod 1, sliding sleeve 5 is along front frame 2 upward sliding gradually, after poppet 3 rotates relative to push rod 1, under the drive of seat post 4, between after poppet 3 and front frame 2, launch along fore-and-aft direction is relative gradually, the front portion of seat post 4 moves downward gradually, drive the front portion of bottom supporting rod assembly 6 to move downward, bottom supporting rod assembly 6 is launched gradually along left and right directions, rear pole assembly 7 also launches along left and right directions thereupon gradually, finally when sliding sleeve 5 slides into after the latched position on top of front frame 2, lockout mechanism locking, go-cart vehicle frame is just stably in Fig. 1, deployed condition shown in Fig. 2.
to sum up, children trolley of the present invention, it is simple in structure, and rod member quantity is few, folding with to launch operation all very convenient, when folding go-cart vehicle frame can be along left and right and fore-and-aft direction draw in, the compact conformation after folding, take up room little, and can certainly stand on ground, can be convenient for carrying and deposit.
above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
