The specific embodiment
below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is further elaborated.
referring to each children trolley shown in the drawings, comprise have deployed condition and folded state go-cart vehicle frame, be located at the wheel assembly of go-cart bottom of frame, for go-cart vehicle frame is locked in to the lockout mechanism under deployed condition.Go-cart vehicle frame comprises front frame 1, push rod 2, after poppet 3 and seat bar assembly 4, and wheel assembly comprises the front-wheel 20 of being located at front frame 1 bottom and the trailing wheel 30 of being located at after poppet 3 bottoms.
referring to shown in Fig. 1 to Fig. 4, the bottom of push rod 2 can be located on front frame 1 by relative front frame 1 slidably along the length bearing of trend of front frame 1, herein, front frame 1 has hollow tube chamber, the bottom of push rod 2 can be plugged in the hollow tube chamber of front frame 1 slidably along self length bearing of trend, between push rod 2 and front frame 1, be provided with the locking piece for both are locked, when this locking piece locking, push rod 2 is relative with front frame 1 fixing, when locking piece release, push rod 2 relatively front frame 1 slides up and down.
the upper pivot of after poppet 3 is connected on the top of push rod 2, and a seat bar assembly 4 extends along fore-and-aft direction, and seat bar assembly 4 can along the fore-and-aft direction folding of go-cart vehicle frame be located between front frame 1 and after poppet 3.Shown in each accompanying drawing, seat bar assembly 4 comprises that the fixed link 42, the back pivot that are fixedly arranged on front frame 1 are connected to the present supermedial back support bar 44 of bar 41 of seat bar 41, bottom pivotal joint on after poppet 3, the seat middle part of bar 41 and the rear portion phase pivot of fixed link 42 are connected, the front portion of fixed link 42 has for supporting the hook-shaped support portion 43 with permanent seat bar 41 front portions, as shown in Figure 1.This hook-shaped support portion 43 opening up, its hook portion forms an opening up accepting groove, and this accepting groove matches with the front portion of seat bar 41, and the front portion of seat bar 41 can be fastened in above-mentioned accepting groove or with accepting groove and be separated to corresponding matching.
shown in each accompanying drawing, this go-cart vehicle frame also comprises grab rail 5, this grab rail 5 is set in the top of front frame 1 regularly by connector bushing 51, grab rail 5 is provided with for the unlock piece with the above-mentioned locking piece release of front frame 1 to locking push rod 2, is made as unlocking knob 6 herein.Shown in Fig. 4, Fig. 5, in the present embodiment, what above-mentioned locking piece adopted is the fit form of lock pin 8 and lockhole, on front frame 1, lock pin 8 is set, on push rod 2, offer the lockhole with lock pin 8 corresponding cooperations, between lock pin 8 and unlocking knob 6, by trailing cable 9 interlocks, arrange.When locking piece locks, lock pin 8 is plugged in lockhole and front frame 1 and push rod 2 is interfixed; And when rotation is during unlocking knob 6, unlocking knob 6 rotates and pulls lock pin 8 by trailing cable 9, make lock pin 8 depart from lockholes, and then can make push rod 2 relatively front frame 1 slide up and down.Certainly, unlock piece also can be located on push rod 2, and it can adopt the form of release handle, and release handle and lockpin ventilating are crossed trailing cable and be connected and locking piece is carried out to release.
this go-cart vehicle frame also comprises for the tarpaulin rod assembly 7 of tilt is installed, tarpaulin rod assembly 7 is fixedly mounted on push rod 2 by paulin seat 71, paulin seat 71 on push rod 2, be positioned at after poppet 3 and push rod 1 pivotal joint place below, while arranging, for ease of installing certainly, also the upper pivot of after poppet 3 can be connected on paulin seat 71.The bar portion that is arranged in paulin seat 71 belows herein on push rod 2 inserts the hollow cavity of front frame 1 slidably.
like this, when go-cart vehicle frame is during in deployed condition, shown in Fig. 1, Fig. 2, seat bar assembly 4 is fixedly supported between front frame 1 and after poppet 3 along fore-and-aft direction, wherein the front support of seat bar 41 is on fixed link 42 and be fastened in the accepting groove of fixed link 42 front portions and interfix with fixed link 42, front frame 1 is locked and is interfixed by locking piece with push rod 2, and front frame 1 extends along same length direction with push rod 2, between front frame 1 and push rod 2, after poppet 3, seat bar assembly 4, form triangular structure.
when needs fold, rotation unlocking knob 6 is by locking piece release, make push rod 2 and the front frame 1 can relative sliding, now mentioning grab rail 5 upwards draws, as shown in Figure 3, the bottom of push rod 2 is along length direction down sliding in front frame 1 of front frame 1, drive after poppet 3 to rotate and to front frame 1, draw close gradually relative to push rod 2, rotate and rotate relative to fixed link 42 front portion of a bar 41 relative to after poppet 3 at the rear portion that simultaneously drives seat bar 41, thereby make a bar 41 turn over and draw close towards after poppet 3 on gradually, front frame 1, push rod 2, between after poppet 3, mutually draw close, and seat bar 41 and back support bar 44 are drawn between front frame 1 and after poppet 2, form folded state as shown in Figure 6, cart structure after folding is compact, small volume.
when needs launch go-cart to use, only need upwards pull push rod 2, make push rod 2 along front frame 1 upward sliding, up along with push rod 2, after poppet 3 rotates and relatively after front frame 1, moves gradually relative to push rod 2, drive seat bar 41 to rotate relative to after poppet 3 and fixed link 42, move towards fixed link 42 gradually the front portion of seat bar 41, until on the hook-shaped support portion 43 of front support on fixed link 42 of seat bar 41 and be fastened in accepting groove, and after locking by locking piece between push rod 2 and front frame 1, go-cart vehicle frame is in stable deployed condition.
in the go-cart vehicle frame of above-described embodiment, also can be set to push rod 2 and there is hollow tube chamber, and the top of front frame 1 can be plugged in the hollow tube chamber of push rod 2 slidably along self length direction, grab rail 5 is located on push rod 2 simultaneously, this can realize folding and spreading principle same as the previously described embodiments equally, but, due to the setting of seat bar assembly 4 and the height and position requirement of grab rail 5, the part that the top of front frame 1 can be inserted in push rod 2 is unsuitable long, often cause the sliding stroke of front frame 1 to be restricted, the integral structure size that the go-cart body frame structure for automotive size of employing this set structure is compared above-described embodiment is larger, in addition, when folding, user also can not realize folding by directly lifting grab rail 5.
to sum up, children trolley of the present invention, it is simple for structure, compact, light, folding all very convenient with expansion operation, and compact conformation and small volume after folding are easy to use and carry, 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.
