Detailed description of the invention
With specific embodiment, the technical solution of the utility model is further elaborated below in conjunction with the accompanying drawings.
Seeing shown in Fig. 1 to Fig. 3, a kind of folding tricycle, including having the deployed condition vehicle frame with folded state, for this vehicle frame is locked locking mechanism in the deployed state.
This vehicle frame includes:
Front fork assembly 1, this front fork assembly 1 include front fork, be pivotally connected on front fork can front fork swings relatively connector 13, be located at the front-wheel 14 of front fork bottom, specifically, front fork includes two vertically extending front fork stems 11, is located at the vertical handgrip 12 at two front fork stem 11 tops regularly, and front-wheel 14 is rotatably arranged between the bottom of two front fork stems 11.Connector 13 is pivotally connected on two front fork stems 11 by bearing pin 15, and the axial line of this bearing pin 15 is vertically extending；
Crossbeam 3, this crossbeam 3 extends along the longitudinal direction, and the front portion of crossbeam 3 is pivotally connected on connector 13 by the first axle 8；
Rear wheel frame 2, the front portion of this rear wheel frame 2 is pivotally connected on connector 13 by the second axle 9, and the rear portion of rear wheel frame 2 is respectively provided on two sides with trailing wheel 23, and the axial line of this second axle 9 and the axial line of the first axle 8 are parallel to each other and extend the most in left-right direction.Specifically, this rear wheel frame 2 includes the back stay 21 laying respectively at the left and right sides, the cross bar 22 being fixedly connected between this two back stay 21 rear portion, the front portion of two back stays 21 is pivotally connected on connector 13 commonly through the second axle 9, and the rear portion of each back stay 21 is equipped with trailing wheel 23.Cross bar 22 is in downward opening U-shaped；
Strut 5, the provided at one of this strut 5 is connected on the rear portion of rear wheel frame 2, and its other end is pivotally connected sliding part 6, and this sliding part 6 is located on crossbeam 3 slidingly back and forth.Specifically, strut 5 is vertically extending, and its underpart is pivotally connected on the middle part of cross bar 22.What sliding part 6 used is to be set in the sliding sleeve on crossbeam 3 slidably；
Connecting rod 4, the provided at one of this connecting rod 4 is connected on rear wheel frame 2, and its other end is pivotally connected on crossbeam 3 by the 3rd axle 10, and the 3rd axle 10 is positioned at the front of sliding part 6 on crossbeam 3.
So, constitute quadric chain between crossbeam 3, rear wheel frame 2, connecting rod 4 and connector 13, between crossbeam 3, rear wheel frame 2, strut 5 and connector 13, constitute another quadric chain.In the present embodiment, locking mechanism use for be located between sliding part 6 and crossbeam 3 the locking piece (not shown) for both being locked.
Vehicle frame also includes seat board 7, and this seat board 7 is positioned at the rear upper of crossbeam 3, and this seat board 7 is located on sliding sleeve 6 regularly herein.Motor or pedal can be set on vehicle frame to drive trailing wheel 23 to rotate, as car load power resources.
See shown in Fig. 1, Fig. 2, this tricycle is under deployed condition, locking piece locking makes sliding part 6 be locked on crossbeam 3, and connecting rod 4 is supported between the front portion of rear wheel frame 2 and the front portion of crossbeam 3, triangle structure between crossbeam 3, connector 13, rear wheel frame 2 and connecting rod 4；Strut 5 support stands between the rear portion of rear wheel frame 2 and the rear portion of crossbeam 3, the most triangle structure between crossbeam 3, connector 13, rear wheel frame 2 and strut 5, vehicle frame is under stable deployed condition, and front fork can swing to realize front-wheel 14 and turn to by opposite joints 13.
When tricycle is folded by needs, first releasing the locking between sliding part 6 and crossbeam 3, then order about front fork and overturn forward, so, rear wheel frame 2 rotates around the second axle 9 opposite joints 13 so that the bottom of rear wheel frame 2 and front fork is gradually drawn close；Crossbeam 3 rotates around the first axle 8 opposite joints 13, and simultaneously under the effect of connecting rod 4, sliding part 6 slides backward relative to crossbeam 3 and orders about strut 5 and rotate so that strut 5 is gradually drawn close with crossbeam 3, and then rear wheel frame 2 is gradually close together with crossbeam 3.Vehicle frame after folding is as it is shown on figure 3, front fork, rear wheel frame 2 and crossbeam 3 are closely close together, and front-wheel 13 is between two back stays 21, and the body frame structure for automotive after folding is compact, takes up room less.When carrying out aforesaid operations, operator can directly carry vertical handgrip 12, and under the effect of the rod member self gravitations such as crossbeam 3 and rear wheel frame 2, rear wheel frame 2 will automatically be drawn close relative to front fork mutually, crossbeam 3 the most automatically opposing rear wheels frame 2 phase is drawn close, realize the auto-folder of vehicle frame, operate more convenient.
Certainly, when vehicle frame is folded, it is also possible to promote seat board 7 immediately rearward so that it is drive sliding part 6 to slide backward along crossbeam 3, and then realize relatively rotating and realizing the folding of vehicle frame between each rod member on vehicle frame.
To sum up, tricycle of the present utility model, its rod member quantity is few, simple for structure, can be folded up when not in use, each rod member on folding rear carriage can closely be close together, and structure is the compactest, taking up room less, the daily storage for user brings conveniently with carrying.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this, can not limit protection domain of the present utility model with this.All equivalence changes made according to this utility model spirit or modification, all should contain within protection domain of the present utility model.
