Referring to figure 1 – Fig. 8, a kind of above-mentioned commercial vehicle/comm..vehicle is with convertible using method of marking time, and this using method comprises marking time to be put down step and packs up step with marking time;
Described marking time put down step and referred to: with pin pin is handled the inside that piece 31 pushes the vehicle body connecting portion 1 of hollow vertically earlier, pin is handled piece 31 and is driven further insertion vehicle body connecting portion 1 of moving lever 32, spring 33 sheathed on the moving lever 32 is compressed, simultaneously, moving lever 32 drives slot fork 36 and moves ahead, enter the inside of wide mouthful of fork 35 until groove 44, at this moment, under the effect of pedal 2 gravity, pedal 2 drives rotating shaft 4 and is rotated down along cw, fastens until rotating shaft 4 and wide mouthful of fork 35, and pedal 2 no longer continues to be rotated down, at this moment, mark time and be in down state;
Described marking time packed up step and referred to: after pedal 2 is finished using, earlier triggering pedal 2 with pin rotates up along conter clockwise, pedal 2 drives rotating shaft 4 along left-hand revolution, when rotating shaft 4, when wide mouthful of fork 35 breaks away from fastening state gradually, spring 33 is handled pin piece 31 vertically and is outwards ejected, the pin of outer bullet is handled piece 31 and is driven moving lever 32 layman, layman's moving lever 32 drives wide mouthful of fork 35 layman, when groove 44 was positioned at slot fork 36 inside, slot fork 36 fastened with groove 44, and the left-hand revolution of rotating shaft 4 finishes, simultaneously, pedal 2 is fixed in rotating shaft 4 can not rotate up it again along conter clockwise, at this moment, marking time is positioned at collapsed state.
Described marking time put down in the step, and when rotating shaft 4 fastened with wide mouthful of fork 35, the angle that rotating shaft 4 rotates clockwise was 90 degree;
Described marking time packed up in the step, and when slot fork 36 fastened with groove 44, rotating shaft 4 was 90 degree along the angle of left-hand revolution.
Principle of the present invention is described as follows:
When to be used: referring to figure 1 – Fig. 5, mark time and be in collapsed state this moment, vehicle body connecting portion 1(hollow structure is radially passed in rotating shaft 4, can be the square steel tube on the automobile battery framework, U font channel-section steel or self-control support etc.) on shaft hole 11, rotating shaft limiting section 41 is stuck on the outer wall of vehicle body connecting portion 1, the rotation hangers 21 that arranges on rotating shaft connecting portion 43 and the pedal 2 is captiveed joint, rotating shaft pars intermedia 42 is positioned at the inside of vehicle body connecting portion 1, the groove 44 that arranges on it fastens with its outside sheathed slot fork 36, slot fork 36, wide mouthful of fork 35, fixed block 34 all is positioned at the inside of vehicle body connecting portion 1, the fixed orifice 12 that arranges on fixed block 34 and the vehicle body connecting portion 1 is captiveed joint spring 33, pin is handled the outside that piece 31 all is positioned at vehicle body connecting portion 1.At this moment, because slot fork 36 blocks groove 44 so that rotating shaft 4 can not be rotated, thereby rotating shaft 4 can overcome the influence of pedal 2 gravity, falls along its gravity direction to avoid pedal 2, thereby is in the state of packing up.
Putting down marks time refers to: referring to Fig. 2,3,4 and Fig. 6, when using, earlier with pin pin is handled the inside that piece 31 pushes the vehicle body connecting portion 1 of hollow vertically, pin is handled piece 31 and is driven the inside that moving lever 32 further inserts vehicle body connecting portion 1, spring 33 sheathed on the moving lever 32 is compressed, simultaneously, moving lever 32 drives slot fork 36 and moves ahead, because the maximum open height of slot fork 36 is smaller or equal to the minimal openings height of wide mouthful of fork 35, thereby, groove 44 can fall back and enter the inside of wide mouthful of fork 35, because the maximum open height of wide mouthful of fork 35 is greater than the spacing between two grooves 44, thereby when groove 44 enters wide mouthful of fork 35 inside, wide mouthful of fork 35 no longer can block groove 44, rotating shaft 4 is no longer limited, under the influence of pedal 2 gravity, pedal 2 falls along clockwise direction, and drive rotating shaft pars intermedia 42 is rotated in a clockwise direction, because the diameter of rotating shaft pars intermedia 42 is more than or equal to the maximum open height of wide mouthful of fork 35, thereby rotate through certain angle when rotating shaft pars intermedia 42, be generally 90 when spending, the sidepiece of rotating shaft pars intermedia 42 and wide mouthful of fork 35 fasten, make wide mouthful of fork 35 just in time can tighten rotating shaft pars intermedia 42, thereby overcome the bounce of spring 33 and the influence of pedal 2 gravity, make that pedal 2 no longer continues to be rotated in a clockwise direction, at this moment, pedal 2 is in the state that puts down.In addition, when pedal 2 was rotated down along cw, the other positioning plates 22 that arrange of rotation hangers 21 also had position-limiting action to it, and namely cross bar 6 blocks positioning plate 22 and continues to be rotated in a clockwise direction to hinder it, thereby restriction pedal 2 continues to be rotated in a clockwise direction.
Packing up marks time refers to: after finishing using, referring to figure 1 – Fig. 5, colluding pedal 2 with pin rotates up along conter clockwise, pedal 2 drives rotating shaft pars intermedia 42 along the conter clockwise contrarotation through rotating shaft connecting portion 43, rotating shaft pars intermedia 42, wide mouthful of fork 35 breaks away from fastening state gradually, at this moment, wide mouthful of fork 35, engaging power between the rotating shaft pars intermedia 42 can't overcome the bounce of spring 33, spring 33 is handled pin piece 31 vertically and is outwards ejected, the pin of outer bullet is handled piece 31 and is driven moving lever 32 layman, layman's moving lever 32 drives wide mouthful of fork 35 layman, is positioned at slot fork 36 again when inner until groove 44, and slot fork 36 engages again with groove 44, the left-hand revolution of rotating shaft pars intermedia 42 finishes, its left-hand revolution certain angle, be generally 90 degree, thereby fixed the pedal 2 that rotates up by rotating shaft 4, it can not be rotated up along conter clockwise again, at this moment, pedal 2 is positioned at collapsed state, and pedal 2 is perpendicular with vehicle body connecting portion 1.
