Described seat board cloth set
It is sheathed on described seat board 21 and slides with 21 relative bars of seat board 141, described backrest cloth cover is fixedly connected between described push rod 11 and described seat board 21 rear end, the lower end of backrest cloth cover is fixing with the rear end that seat board 21 or seat board cloth overlap to be connected, and the left and right sides portion of backrest cloth cover and the push-rod lock locking member 113 of push rod 11 are fixedly connected.In order to improve the comfortableness of dependence, described seat mechanism 2 also includes the backboard 22 of a hard.Described backrest cloth cover is sheathed on described backboard 22, and the push rod 11 of vehicle frame backboard 22 and both sides when expanded position is the most at grade and backboard 22 is less than upper push-rod 111.Vehicle frame is when expanded position, and strut 15, seat board 21, lower push-rod 112 three constitute a triangular structure.And now connector 23 can be relaxed state, can allow seat board 21 within the specific limits relative to seat bar 141 slide anteroposterior, be used for regulating seat board 21 position and backboard 22 angle to the most comfortable use state.During along with vehicle frame folding, lower push-rod 112 is relative with strut 15 to launch, and the angle between strut 15 and lower push-rod 112 becomes big.And in order to make vehicle frame fold smoothly, connector 23 can be become tightening from relaxed state, seat board 21 is provided pulling force by connector 23, so will not continue to move forward with seat bar 141, i.e. relative seat board 21 forward slip of seat bar 141, distance between rear end and the upper end of backrest cloth cover of seat board cloth set will not increase, therefore vehicle frame can fold smoothly, do not have the problem making vehicle frame to fold smoothly because of pullling of cloth set, seat board cloth set slides with seat board 21, will not tractive vehicle frame, it is possible to make vehicle frame fold smoothly.
Shown in accompanying drawing 1 and accompanying drawing 6, when described vehicle frame 1 is at expanded position, seat board 21 is positioned at a top for bar stull 142, seat bar stull 142 and seat bar 141 support seat board 21 jointly, seat bar stull 142 offsets to prevent seat board 21 forward slip with sliding sleeve 211, when seat mechanism 2 is in rearmost, described block 121 offsets to prevent seat board 21 from sliding backward with the rear end of seat board 21, and soft ribbons is relaxed state.Shown in accompanying drawing 4 and accompanying drawing 8, when described vehicle frame 1 is in folding position, soft ribbons is that tensioned state is to stop described seat board 21 the most described seat bar assembly 14 to slide, under the tractive of soft ribbons, seat board 21 and seat board cloth set are close to avoid affecting vehicle frame folding towards seat bar 141 rear end, and the lower end of backrest cloth cover and backboard 22 is moved rearwards by therewith, backrest cloth cover and backboard 22 folding forward, it is to avoid backboard 22 stretches out vehicle frame.
Shown in accompanying drawing 3, in figure, direction shown in arrow is the glide direction of seat board 21.When vehicle frame 1 is folded,
First will be as push-rod lock locking member
113
Electric bell unlock, overturn forward upper push-rod
111
So that it is lower push-rod relatively
112
Close up folding.Then so that locking mechanism unlocks, and sliding part is along fore-stock
12
Slide downward, drives after-poppet
13
Towards fore-stock
12
Draw in forward, drive simultaneously and quadric chain relatively rotates between each rod member and mutually draws close, finally make push rod
11
, seat bar
141
, fore-stock
12
, strut
15
And after-poppet
13
Mutually draw in.
By vehicle frame
1
When opening, the most first by upper push-rod
111
Lower push-rod relatively
112
Rotate and make push rod
11
Launch and by push-rod lock locking member
113
Locking, then sliding part is along fore-stock
12
Upward sliding, each rod member in quadric chain mutually rotates and relatively launches, seat bar simultaneously
141
Drive after-poppet
13
Away from fore-stock
12
Back rotation and relative fore-stock
12
Launch, until mutually launching between each rod member.
Around the present invention addresses, be the most all the concrete bearing definition residing when expanded position of the vehicle frame 1 with this children trolley.Specifically, front and back correspond respectively to " left " " right " of paper in accompanying drawing 1, correspond respectively to up and down paper in accompanying drawing 1 " on " D score, left and right directions is then corresponding to along the direction being perpendicular to paper.
Above-described embodiment only for technology design and the feature of the present invention are described, are a kind of preferred embodiment, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this.All equivalence changes made according to the spirit of the present invention or modification, all should contain within protection scope of the present invention.
