Detailed description of the invention
Below in conjunction with detailed description of the invention and embodiment, the present invention is further described:
If Fig. 1 is to shown in 10, the folding crossbeam formula Portable vehicle of embodiment of the present invention structure, including front-wheel 601, trailing wheel 602, vehicle frame 500, crossbeam 300, bracing frame 400 and vehicle seat 100.
The front end by crossbeam rotating shaft 303 connecting vehicle frame 500, the front end of crossbeam 300, the rear end of crossbeam is provided with vehicle seat 100, and vehicle seat is connected by vehicle seat fixed mount 102 and crossbeam are fixing.Spring shaft 907 it is provided with in vehicle seat fixed mount 102, torsionspring 903 is arranged on spring shaft 907, one end of torsionspring 903 connects one end of throw rod 901, the other end at 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 lays respectively at the both sides of bracing frame 400 and is rotationally connected by support bar rotating shaft 404 with the respective side of the upper end of bracing frame, the lower end of bracing frame 400 is rotationally connected with vehicle frame 500 by under support bar rotating shaft 403, slide is provided with locating slot 906, when crossbeam is in operating position, the hook that throw rod end is arranged hangs on the cell wall of locating slot.When upwards pulling the tail end of throw rod, hook departs from the cell wall of fixing groove, after slide resets, and the tail end of pressure throw rod, make it hang on the cell wall of locating slot in hook press-in locating slot, thus fixing slide carriage.The length of preferred crossbeam and bracing frame and curve shape enable to crossbeam and bracing frame folding time slide be positioned at above trailing wheel.When Portable vehicle is in normal operating conditions, slide is positioned at the lower section of vehicle seat, the hook of throw rod be positioned on slide arrange locating slot, slide passes through torsionspring, throw rod, hook, locating slot and vehicle seat fixed mount 102 are fixed on crossbeam, simultaneously, now it is integrally fixed on crossbeam due to slide, fix relative to the position of crossbeam, under the combined effect of bracing frame and crossbeam, crossbeam, the rotational angle of bracing frame is restricted, therefore when Portable vehicle is walked, crossbeam is positively retained at 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 comfortableness by bus.Throw rod only need to be pulled when needs folding portable car, hook is released by throw rod under the effect of torsionspring in locating slot, then the restriction of crossbeam and bracing frame is released from, or pull throw rod, make hook depart from fixing groove, pull the slide being arranged on slide rear handle 905 to make slide to crossbeam rear slide on crossbeam, be pressed downward against crossbeam, crossbeam and the equal rear wheel of bracing frame rotate and are adjacent to trailing wheel, it is achieved Portable vehicle completely folding.When Portable vehicle needs normally to use, crossbeam and bracing frame upwards being started, slide slips back to operating position along crossbeam, and throw rod enters into locating slot, crossbeam and bracing frame is fixed.
Device for locking sliding base may be used without following structure: the other end of throw rod 901 connects buckle 901, and buckle is connected with the locating slot clamping being arranged on slide, and when crossbeam is in operating position, buckle is stuck in locating slot.
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 support bar 401 and the second support bar 402, first crossbeam bar 301 and second cross beam bar 302 lay respectively at the both sides of vehicle frame 500, it is rotationally connected with the front end of the respective side of vehicle frame 500 respectively by the front end of the front end of first crossbeam bar 301 and second cross beam bar 302, it is rotationally connected by the flank one of in support bar rotating shaft 404 with slide 904 by the upper end of the first support bar 401, it is rotationally connected by the flank two of in support bar rotating shaft 404 with slide by the upper end of the second support bar 402, it is rotationally connected by under support bar rotating shaft 403 with the middle part of the respective side of vehicle frame respectively by the lower end of the lower end of the first support bar and the second bearing bar, after so making Portable vehicle folding lighter.
In order to further increase portability, vehicle frame, crossbeam and bracing frame all can be arranged respectively to single-side structural, or are all provided with being set 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 support bar 401 and the second support bar 402 is only set, first crossbeam bar is connected by the first support bar of respective side, or being connected second cross beam bar by the second support bar of respective side, two flanks of slide 904 all connect in ground support bar or the second support bar.
Then crossbeam can be configured as 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 support bar are all connected with the first bearing bar of respective side or second cross beam bar 302 and the second support bar are all connected with the second bearing bar of respective side.
