shown in composition graphs 4,5,8,11,12, a kind of electric unicycle described in the present embodiment tow device, include and be fixedly mounted in electric unicycle car shell and the flexible tube-pulling apparatus that can stretch out from electric unicycle front upper place or back upper place, and by two rollers being positioned at car shell both sides that linkage is connected with flexible tube-pulling apparatus, described flexible tube-pulling apparatus forward upward or back upper place make linkage driving rolls stretch out to the electric unicycle back lower place or front lower place while stretching out, and roller extend out to end position and earth surface.Described flexible tube-pulling apparatus includes two groups of trombone slides that stretch, and often the flexible trombone slide of group comprises three or four telescopic pipes being slidably socketed successively, and two groups of trombone slide symmetries of stretching are arranged on car shell both sides inwall; Outermost one deck telescopic pipe is outer tube 3, and outer tube is fixedly connected on car shell madial wall, and in outer tube, the telescopic pipe of one deck is lower trombone slide 4, interior one deck telescopic pipe be upper trombone slide 6, two groups of trombone slides that stretch upper trombone slide upper end between be connected with a handle rod 7; Described roller 1 is arranged on roller mounting rod 2 lower end, and roller mounting rod is hinged on car shell inwall, and roller and handle rod are in homonymy; Described linkage is connected between the upper end of roller mounting rod 8 and lower trombone slide 4, and linkage includes a roller pull bar 9, and roller pull bar 9 upper end is fixedly connected with lower trombone slide 4 bottom, and roller pull bar lower end and roller mounting rod 8 upper end are rotationally connected.Described roller pull bar at least includes the draw-in bar 92 and outside link 91 that are slidably socketed, and outside link lower end and roller mounting rod upper end are rotationally connected, and draw-in bar upper end is fixedly connected with lower trombone slide bottom.
the bottom of described lower trombone slide be provided with one to coordinate with outer tube top locate there is elastomeric location fastener 42, one end of described location fastener is fixedly connected on the madial wall of lower trombone slide, the other end of location fastener is bent to form the guiding kink 422 extended towards lower trombone slide opposite side madial wall, the wall that location fastener and lower trombone slide are fitted is integrally formed with dop 421, lower trombone slide sidewall offers the through hole passed for dop, the sidewall on described outer tube top offers and coordinates locking upper knock hole 301 with described dop; Location fastener differs between the wall of dop side and lower trombone slide opposite side inwall and is fixed with spring 43; The guiding kink that described middle trombone slide 5 moves down its bottom extruding location fastener in process makes dop and upper knock hole depart from.
as shown in Figure 5, the upper limit portion that described middle trombone slide 5 upper end can arrange indent coordinates with the lower limit portion that upper trombone slide bottom is arranged, to guarantee that middle trombone slide and upper trombone slide do not depart from.Also can arrange location fastener in middle trombone slide 5 to coordinate with lower trombone slide.
described upper trombone slide 6 is made up of the fixing upper trombone slide 6a be hinged and the upper trombone slide 6b of rotation, and handle rod 7 is fixedly connected with the upper end of trombone slide 6b in the rotation of both sides.
described middle trombone slide can need to arrange 1-2 joint according to the entire length of flexible trombone slide, and also can save middle trombone slide, namely flexible trombone slide is made up of three telescopic pipes, and middle trombone slide above-mentioned accordingly can be replaced by pull-up pipe belt.
during use, by upwards pulling handle rod 7, upper trombone slide, middle trombone slide, lower trombone slide are pulled out successively, the draw-in bar be fixedly connected with lower trombone slide moves up thereupon, after draw-in bar and outside link are stretched to end position, outside link pulls roller mounting rod to rotate clockwise, to the upper knock hole of the dop and outer tube that fastener located by lower trombone slide coordinate locking after, the restriction that roller mounting rod is subject to roller pull bar cannot rotate counterclockwise, thus support in the lump on the ground with wheel Q, electric unicycle can be dragged by handle rod 7 and advance.Pressing down handle rod drives upper trombone slide, middle trombone slide, lower trombone slide to return in the process in outer tube, and lower trombone slide drives draw-in bar to move down, and after draw-in bar takes in outside link completely, outside link then driving rolls mounting rod rotates counterclockwise and gets back to initial position.
it is length in order to reduce bar section on the left of roller mounting rod and car shell hinged place that described roller pull bar is made up of draw-in bar, outside link, make use of the principle of lever, reduces the arm of force, comparatively require great effort when so pulling roller mounting rod to rotate.When the space in car shell is enough, roller pull bar also can adopt the single body of rod.
the present embodiment is compared with embodiment 1,2,3,4, its advantage also comprises the length of roller mounting rod 8 and each joint telescopic pipe and angle of inclination can adjust neatly, according to the deployment scenarios of other parts in car shell, the installation site of flexible tube-pulling apparatus and roller mounting rod can be selected better.
embodiment 6
composition graphs 5, 6, 7, 8, 11, shown in 12, the present embodiment is with the difference of embodiment 5: the bottom of described lower trombone slide be provided with one to coordinate with outer tube top locate there is elastomeric location fastener, one end of described location fastener 42 is fixedly connected on the madial wall of lower trombone slide, the other end of location fastener is bent to form the guiding kink 422 extended towards lower trombone slide opposite side madial wall, the wall that location fastener and lower trombone slide are fitted is integrally formed with dop 421, lower trombone slide sidewall offers the through hole passed for dop, the sidewall on described outer tube top offers and coordinates locking upper knock hole 301 with described dop, the wall that location fastener differs from dop side is integrally formed with kelly 423, lower trombone slide sidewall offers the through hole passed for kelly end, the sidewall of described outer tube bottom offers and coordinates locking lower knock hole 302 with described kelly end, locate between the wall at kelly place on fastener and lower trombone slide opposite side inwall and be fixed with spring 43, the guiding kink that in described lower trombone slide, the telescopic pipe of one deck moves down extruding location, its bottom in process fastener makes dop and upper knock hole depart from, or make kelly end and lower knock hole locking.
relative embodiment 5, the present embodiment is by being provided with kelly, roller and flexible tube-pulling apparatus collapsed state are fixed, after dop and upper knock hole depart from, middle trombone slide pushes lower trombone slide and moves down, after lower trombone slide reaches the limit of position, middle trombone slide continues to move down a bit of distance, the sidewall of middle trombone slide lower end is stuck in location fastener and is provided with between the wall of dop side and lower trombone slide madial wall, force kelly end to snap among lower knock hole, such roller would not produce due to Action of Gravity Field the possibility rotated.After pull-up hand lever 7 makes middle trombone slide moves again, kelly just can depart from lower knock hole.
