Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical scheme is further elaborated.
Referring to the child umbrella handle vehicle shown in Fig. 1～3, including have deployed condition and folded state vehicle frame, be located at the bottom of vehicle frame anterior front-wheel 3, be located at the trailing wheel 4 at rear portion at the bottom of vehicle frame, for vehicle frame being locked in the locking mechanism (not shown) of deployed condition, the end cross structure 1 that vehicle frame includes the side stand 2 in both sides, is connected between both sides side stand 2 and can stretch along the longitudinal direction.
The side stand 2 of every side all includes fore-stock 21, after-poppet 22 and push rod 23, and the top of fore-stock 21 rotates with the bottom of push rod 23 and is connected, and the top of after-poppet 22 is connected on push rod 23 rotationally.End cross structure 1 includes at least two group cross strut groups, and what adopt is two groups of cross strut groups herein, and two groups of cross strut groups are arranged along the fore-and-aft direction of vehicle frame.
Often group cross strut group all includes intersecting and passing through, at infall, first connecting rod 11 and the second connecting rod 12 that the first pivot 15 is articulated, the front end of the first connecting rod 11 of the rear end of the first connecting rod 11 of previous group cross strut group and later group cross strut group is articulated by the second pivot 16, the front end of the second connecting rod 12 of the rear end of the second connecting rod 12 of previous group cross strut group and later group cross strut group is articulated by the 3rd pivot 17, and the axial line of first pivot the 15, second pivot 16 and the 3rd pivot 17 is parallel to each other and is all vertically distributed.The front end of first connecting rod 11 of previous group cross strut group and the front end of second connecting rod 12 are connected to the bottom of the fore-stock 21 of both sides rotationally respectively through the first connector 13, and the rear end of the first connecting rod 11 of later group cross strut group and the rear end of second connecting rod 12 are then connected to the bottom of the after-poppet 22 of both sides rotationally respectively through the second connector 14.In the present embodiment, the unsettled setting in junction of two groups of adjacent cross strut groups, namely it is not connected with vehicle frame.
Shown in Figure 1, first connector 13 has horizontal edge and vertical edge, substantially L-shaped structure, wherein the vertical edge of the first connector 13 is connected on fore-stock 21 by the first rotating shaft 18, the front end of the horizontal edge of the first connector 13 and the first connecting rod 11 of previous group cross strut group or the front end of second connecting rod 12 are rotated by the second rotating shaft 19 and are connected, the axial line of the first rotating shaft 18 is horizontally extending, the axial line of the second rotating shaft 19 and the first pivot 15, the axial line of the second pivot 16 and the 3rd pivot 17 is parallel to each other, namely its axial line vertically extends.
Similarly, second connector 14 is also configured as the L-type structure having horizontal edge with vertical edge, rotated by the 3rd rotating shaft (not shown) between the vertical edge of the second connector 14 and after-poppet 22 and be connected, the axial line of the 3rd rotating shaft is distributed in the horizontal direction, the horizontal edge of the second connector 14 and the rear end of the first connecting rod 11 of later group cross strut group or the rear end of second connecting rod 12 are rotated by the 4th rotating shaft (not shown) and are connected, and the axial line of the 4th rotating shaft is also vertically distributed.So, this end cross structure just can be stretched along vehicle frame fore-and-aft direction, and both sides side stand 2 also can be driven mutually to draw close in left-right direction or separate simultaneously.
For convenience of the installation of the 1 of end cross structure, in first connecting rod 11,12 two parts of second connecting rod, have at least parts along its length in the wavy shaped configuration of dipping and heaving.In the present embodiment, first connecting rod 11, second connecting rod 12 are disposed as wavy shaped configuration, intersect place at first connecting rod 11 and second connecting rod 12, wherein this position of a connecting rod raises up, this position of an other connecting rod is to recessed, make often to organize first connecting rod 11 when cross strut group is drawn in mutually and be substantially in same plane with second connecting rod 12, also make end cross structure 1 be connected to the position on fore-stock 21 and after-poppet 22 in sustained height simultaneously, so can be easy to processing and install.
Shown in Fig. 1～3, the vehicle frame of this umbrella handle vehicle also includes being connected between both sides after-poppet 22 and can along the rear pole structure 5 of the left and right directions folding of vehicle frame, when vehicle frame is in deployed condition, this rear pole structure 5 is launched and is provided both sides after-poppet along the support of vehicle frame left and right directions；When vehicle frame is in folded state, rear pole structure 5 is folding and realizes the folding of vehicle frame left and right directions.This vehicle frame is additionally provided with bar 6, the rear portion of bar 6 is rotatably connected to the bottom of push rod 23 or the top of fore-stock 21, in the present embodiment, the rear portion of this bar 6, the bottom of push rod 23 and the top of fore-stock 21 are rotationally connected with same place, and bar 6 can be arranged to folding along the left and right directions of vehicle frame, on this vehicle frame, locking mechanism can adopt and be located at the electric bell being rotationally connected place between bar 6, push rod 23 and fore-stock 21.
Shown in Fig. 1, Fig. 2, vehicle frame is in deployed condition, and locking mechanism locks, and end cross structure 1 and rear pole structure 5 are in deployed condition.When needs are by time folding for this umbrella handle vehicle, locking mechanism is unlocked, then push rod 23 is overturn forward from the top of push rod 23, push rod 23 and after-poppet 22 are drawn close gradually, push rod 23 is turned over before continuation, the bottom of fore-stock 21 moves forward gradually, or the bottom of after-poppet 22 moves gradually afterwards, this drives the first connecting rod 11 of each group of cross strut group in end cross structure 1 to rotate against with second connecting rod 12, and the front and back end of first connecting rod 11 and second connecting rod 12 is respectively correspondingly drawn close gradually, drive rear pole structure 5 along the left and right directions folding of vehicle frame simultaneously, the both sides side stand 2 making vehicle frame is drawn close mutually.Body frame structure for automotive after folding is flat, and compact conformation takes up room less.
When needs launch this vehicle frame, then upwards lift push rod 23, push rod 23 is a little turned over around itself and being rotationally connected of fore-stock 21, front-wheel 3 and trailing wheel 4 are drawn close gradually, the front and back end of the first connecting rod 11 and second connecting rod 12 of often organizing cross strut group in end cross structure 1 is respectively correspondingly gradually disengaged, drive rear pole structure 5 is launched along the left and right directions of vehicle frame simultaneously, the both sides side stand 2 making vehicle frame is located remotely from each other, when push rod 23 upset is to when specifying position, locking mechanism locks, and vehicle frame returns back to expansion serviceable condition.Fold and open all very convenient.
Above-described embodiment only for technology design and the feature of the present invention are described, 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 equivalences made according to spirit of the invention change or modify, and all should be encompassed within protection scope of the present invention.
