The specific embodiment
below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further elaborated.
below in the definition about direction, be all according to this children trolley when the deployed condition, in go-cart, viewed direction is defined children's sitting.
referring to the children trolley shown in Fig. 1～8, there is the go-cart vehicle frame of expanded position and folding position, the front component 13 of being located at go-cart bottom of frame and wheel assembly 14, for go-cart vehicle frame being locked in to the lockout mechanism of expanded position.
this go-cart vehicle frame comprises the side stand that is positioned at both sides, the side stand of every side includes after poppet 3 that front frame 2, bottom that push rod 1, bottom be provided with front component 13 be provided with wheel assembly 14, is located at the seat bar 4 between push rod 1 and after poppet 3, and this side stand also comprises first connecting rod 5 and second connecting rod 6.
push rod 1 can along self length direction folding arrange, it can be expansion link, also can be set to the upper push-rod being mutually rotationally connected 102 and the lower push-rod 101 of the present embodiment, switching place between upper push-rod 102 and lower push-rod 101 is provided with push rod locking piece 103, this push rod locking piece 103 can adopt electric bell, during its release, upper push-rod 102 relatively lower push-rod 101 overturns and by push rod 1 folding.
the seat front portion of bar 4 and the bottom of lower push-rod 101 rotate and are connected, be connected on after poppet 3 to the posterior rotation of seat bar 4, one end of the top of the top of after poppet 3, front frame 2 and first connecting rod 5 connects mutually rotationally by the first axle 8, the other end of first connecting rod 5 is connected on lower push-rod 101 rotationally, between first connecting rod 5, lower push-rod 101, seat bar 4 and after poppet 3, forms four-bar linkage.
one end of second connecting rod 6 is connected on front frame 2 rotationally, its other end is connected to rotationally the bottom of lower push-rod 101 or connects rotationally on the front portion of present bar 4, in the present embodiment, the front portion of the above-mentioned other end of second connecting rod 6, the bottom of lower push-rod 101, seat bar 4 links together mutually rotationally by the second axle 9, and the axial line of the axial line of the second axle 9 and the first axle 8 arranges in parallel to each other.Like this, between lower push-rod 101, first connecting rod 5, front frame 2 and second connecting rod 6, form four-bar linkage, between seat bar 4, after poppet 3, front frame 2 and second connecting rod 6, also form four-bar linkage.
lockout mechanism can be located at arbitrary switching place on the four-bar linkage forming between first connecting rod 5, lower push-rod 101, seat bar 4 and after poppet 3, also can be located at switching place between switching place between second connecting rod 6 and front frame 2 or second connecting rod 6 and lower push-rod 101, bar 4 front portion.During this lockout mechanism locking, above-mentioned four-bar linkage, all in stable state, makes go-cart vehicle frame under stable deployed condition.During lockout mechanism release, can adjust by the state of the four-bar linkage to above-mentioned, thereby can make go-cart vehicle frame be deployed under multiple different state.
in the present embodiment, lockout mechanism is to be located at the electric bell 10 that is rotationally connected place between front frame 2, after poppet 3 and first connecting rod 5, and this electric bell 10 is for locking the locking between after poppet 3 and first connecting rod 5.Between the side stand of both sides, be also provided with cross bar 11, this cross bar 11 is fixedly attached between the electric bell 10 of both sides, cross bar 11 is provided with for the unlocking knob 12 to electric bell 10 releases, only needs singlehanded rotation unlocking knob 12 only to need release to electric bell 10, easy to operate.Certainly, also cross bar 11 can be set, but come electric bell 10 releases by unlock button is set on electric bell 10, but arrange like this, need the release one by one of bimanualness or one hand, operate comparatively loaded down with trivial details comparatively speaking.
shown in each accompanying drawing, this go-cart vehicle frame also comprises grab rail 7, and grab rail 7 is opening U font backwards, and the two ends of grab rail 7 are removably connected on the first connecting rod 5 of both sides.In the folding process of this children trolley, grab rail 7 can synchronously rotate with first connecting rod 5, and without being taken off.
this children trolley deployed condition as shown in Figure 1 and Figure 2, when needs are folding by this go-cart, first by 103 releases of push rod locking piece, will be turned over before the relative lower push-rod 101 of upper push-rod 102, makes push rod 1 folding, as shown in Figure 3, Figure 4.Then user lifts cross bar 11 and rotates unlocking knob 12 by electric bell 10 releases, now first connecting rod 5, lower push-rod 101, the four-bar linkage forming between seat bar 4 and after poppet 3, lower push-rod 101, first connecting rod 5, the four-bar linkage forming between front frame 2 and second connecting rod 6, seat bar 4, after poppet 3, the four-bar linkage forming between front frame 2 and second connecting rod 6 is all in mobilizable state, under the effect of gravity or forward under the application force of push-and-pull push rod 1, push rod 1 leans forward and drives first connecting rod 5, seat bar 4 and second connecting rod 6 rotate and draw close gradually to front frame 2, simultaneously under the drive of present bar 4, the relative front frame 2 of after poppet 3 is drawn close gradually, as Fig. 5, shown in Fig. 6.Final push rod 1, front frame 2, after poppet 3, seat bar 4, first connecting rod 5 and second connecting rod 6 are drawn close mutually, can be placed on the self-support state shown in Fig. 7, or in Fig. 8, weighing apparatus are placed in ground state after folding.In above-mentioned folding process, substantially can realize one and carry i.e. folding, folding operation is very convenient, and the go-cart body frame structure for automotive after folding is compact, takes up room little.
when needs launch this go-cart to use, under the state shown in Fig. 7, Fig. 8, first the relative lower push-rod 101 of upper push-rod 102 is turned over, push rod 1 is launched, then pull back push rod 1, lower push-rod 101 drives first connecting rod 5, seat bar 4 and second connecting rod 6 to turn over and gradually away from front frame 2, under the drive of present bar 4, the relative front frame 2 of after poppet 3 is turned over and front frame 2 expansion relatively gradually, when being expanded to suitable deployed condition, electric bell 10 lockings, this go-cart vehicle frame is locked under this expanded position, as shown in Figure 1 and Figure 2.
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.
