Detailed description of the invention
Below in conjunction with detailed description of the invention and embodiment, the utility model is further described:
As shown in Fig. 1 to 10, the folding crossbeam formula Portable vehicle of the utility model example structure, comprises front-wheel 601, trailing wheel 602, vehicle frame 500, crossbeam 300, bracing frame 400 and vehicle seat 100.
The front end of crossbeam rotating shaft 303 connecting vehicle frame 500 is passed through in the front end of crossbeam 300, and the rear end of crossbeam is provided with vehicle seat 100, and vehicle seat is fixedly connected with crossbeam by vehicle seat fixed mount 102.Spring shaft 907 is provided with in vehicle seat fixed mount 102, torsion spring 903 is arranged on spring shaft 907, one end of torsion spring 903 connects one end of throw rod 901, the other end of throw rod is provided with hook 908, slide 904 can slide on crossbeam 300, the flank of the left and right sides of slide 904 lay respectively at bracing frame 400 both sides and with the respective side of the upper end of bracing frame by strut bar rotating shaft 404 is rotationally connected, the lower end of bracing frame 400 is by 403 being rotationally connected with vehicle frame 500 under strut bar rotating shaft, slide is provided with positioning groove 906, when crossbeam is in control position, the hook that throw rod end is arranged hangs on the cell wall of positioning groove.When upwards pulling the tail end of throw rod, hook departs from the cell wall of hold down groove, and after slide resets, the tail end of pressure throw rod, makes it hang on the cell wall of positioning groove by hook press-in positioning groove, thus fixing slide carriage.When the length of preferred crossbeam and bracing frame and curve shape can make crossbeam and bracing frame fold, slide is positioned at above trailing wheel.When Portable vehicle is in normal working, slide is positioned at the below of vehicle seat, the hook of throw rod is positioned at the positioning groove that slide is arranged, slide passes through torsion spring, throw rod, hook, positioning groove and vehicle seat fixed mount 102 are fixed on crossbeam, simultaneously, because slide is now fixed on crossbeam, fix relative to the position of crossbeam, under the combined action of bracing frame and crossbeam, crossbeam, the rotational angle of bracing frame is restricted, therefore when Portable vehicle is walked, crossbeam can remain on certain position, but due to the front end of crossbeam, the lower end of bracing frame is all rotationally connected with vehicle frame, and the upper end of bracing frame and crossbeam are rotationally connected, therefore when Portable vehicle is walked, crossbeam has certain elasticity, increase traveling comfort by bus.Only throw rod need be pulled when needs folding portable car, hook is released by throw rod under the effect of torsion spring in positioning groove, then the restriction of crossbeam and bracing frame is removed, or pull throw rod, hook is departed from hold down groove, pulls the slide handle 905 being arranged on slide rear to make slide to crossbeam rear slide on crossbeam, to down transverse beam, crossbeam and bracing frame are all adjacent to rear wheel and trailing wheel, realize the completely folding of Portable vehicle.When Portable vehicle needs normally to use, crossbeam and bracing frame are upwards started, slide slips back to control position along crossbeam, and throw rod enters into positioning groove, crossbeam and bracing frame is fixed.
Device for locking sliding base also can adopt following structure: the other end of throw rod 901 connects buckle 901, and buckle is connected with the positioning groove clamping be arranged on slide, and when crossbeam is in control position, buckle is stuck in positioning groove.
In order to improve the portability of Portable vehicle, crossbeam is made up of first crossbeam bar 301 and second cross beam bar 302, bracing frame is made up of the first strut bar 401 and the second strut bar 402, first crossbeam bar 301 and second cross beam bar 302 lay respectively at the both sides of vehicle frame 500, be rotationally connected with the front end of the respective side of vehicle frame 500 respectively by the front end of first crossbeam bar 301 and the front end of second cross beam bar 302, by the upper end of the first strut bar 401 by strut bar rotating shaft 404 is rotationally connected with the flank one of slide 904, by the upper end of the second strut bar 402 by strut bar rotating shaft 404 is rotationally connected with the flank two of slide, by the lower end of the first strut bar and the second bearing bar lower end respectively with the middle part of the respective side of vehicle frame by 403 being rotationally connected under strut bar rotating shaft, lighter after making Portable vehicle folding like this.
In order to further increase portability, vehicle frame, crossbeam and bracing frame all can be arranged respectively to single-side structural, or are all arranged to single-side structural.
Such as, monolateral crossbeam can be set, as only arranged first crossbeam bar 301 or second cross beam bar 302, first strut bar 401 and the second strut bar 402 is only set, first crossbeam bar is connected by the first strut bar of respective side, or connecting second cross beam bar by the second strut bar of respective side, two flanks of slide 904 all connect in ground strut bar or the second strut bar.
Then crossbeam also can be arranged to monolateral bearing bar, as only arranged the first bearing bar 501 or the second bearing bar 502, then first crossbeam bar 301 and the first strut bar are all connected with the first bearing bar of respective side or second cross beam bar 302 and the second strut bar are all connected with the second bearing bar of respective side.
