Detailed description of the invention
as shown in the drawings, a kind of children trolley, comprise there is the go-cart vehicle frame, front component 31, wheel assembly 32 of expanded position and folding position, for go-cart vehicle frame being locked in to blocking device under expanded position, can dismantling or can be fixedly installed on the seat 17 on go-cart vehicle frame.
concrete, go-cart vehicle frame comprises:
front-wheel support 11, front component 31 is arranged at the bottom of described front-wheel support 11;
rear wheel support 12, the top of the top of described rear wheel support 12 and front-wheel support 11 is rotationally connected around the first axle 21, and wheel assembly 32 is arranged at the bottom of described rear wheel support 12;
seat support 13, the front portion of seat support 13 and front-wheel support 11 are rotationally connected around the second axle 22, and the second axle 22 is positioned at the front of the first axle 21;
supporting pole rack 15, the rear portion of the top of supporting pole rack 15 and described seat support 13 is rotationally connected around the 3rd axle 23, the bottom of supporting pole rack 15 and after poppet are rotationally connected around the 4th axle 24, the 4th axle 24 is positioned at the rear lower of the first axle 21, the 3rd axle 23 to the projection of horizontal surface at the first axle 21 and the second axle 22 respectively between the projection of horizontal surface.
described front-wheel support 11, rear wheel support 12, seat support 13 and supporting pole rack 15 form four-bar linkage.
in the present embodiment, blocking device is arranged between described seat support 13 and supporting pole rack 15.The concrete structure of blocking device is not design main points of the present utility model, as long as the structure locking between two rotatable parts can being suitable at this.The position of blocking device is except being arranged between seat support 13 and supporting pole rack 15, can also be to be arranged between seat support 13 and rear wheel support 12, or between front-wheel support 11 and rear wheel support 12, as long as aforementioned four-bar linkage being locked into triangle mechanism.
seat 17 can dismantle ground or be directly fixedly arranged on seat support 13, can dismantle as preferably.Concrete dismounting mode is not design main points of the present utility model, is not described in detail in this.
in the present embodiment, seat 17 also can fold.Seat 17 comprises the seat frame 171 being arranged on seat support 13, the back rest 172 that bottom is connected with the posterior rotation of seat frame 171, back rest 172 relatively seat frame 171 launches, with folding, between back rest 172 and seat frame 171, to be provided with backrest lockout mechanism.Backrest lockout mechanism is not design main points of the present utility model, as long as the structure locking between two rotatable parts can being suitable at this.Seat 17 can fold itself, therefore when go-cart vehicle frame folding, it need not be disassembled from seat support 13.
go-cart vehicle frame also comprises the push-rod frame 16 being arranged on front-wheel support 11.The top of the bottom of push-rod frame 16 and front-wheel support 11 is rotationally connected around the 5th axle 25, when go-cart vehicle frame is under expanded position, push-rod frame 16 has sweptback positive push mode from bottom to top, and there is the anti-push mode turning forward from bottom to top, between push-rod frame 16 and front-wheel support 11, be provided with push rod detent mechanism.Relation that push-rod frame 16 is and front-wheel support 11 rotates, does not therefore participate in the folding of aforementioned four-bar linkage.Same, push rod detent mechanism is not design main points of the present utility model, as long as the structure locking between two rotatable parts can being suitable at this.When push-rod frame 16 is in the process of positive push mode and the conversion of anti-push mode, by the release of push rod detent mechanism, push-rod frame 16 can be rotated around the 5th axle 25, after commutation, then lock by push rod detent mechanism.
extending back at least partly of the rear portion of seat support 13 forms carrying handle 14.In preferred embodiment of the present utility model, described blocking device is to control blocking device release by the button on carrying handle 14.And on draw carrying handle 14 to control aforementioned four-bar linkage to draw in folding.
if accompanying drawing 3 is to as shown in accompanying drawing 6, when in the process that go-cart vehicle frame is changed to folding position by expanded position, first by the release of backrest lockout mechanism, the relative seat frame 171 of back rest 172 is turned folding and draw close, then by the release of push rod detent mechanism, the relative front-wheel support 11 of push-rod frame 172 is turned folding and draw close, again by blocking device release, aforementioned four-bar linkage is folding to be drawn in, and whole push rod vehicle frame folding draws in, simple in structure.
vice versa, first aforementioned four-bar linkage is launched, and blocking device locking, then push-rod frame 16 is launched and lock by push rod detent mechanism, then seat 17 is launched.
above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
