The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment one, referring to Fig. 1,3,4, chooses the rocker-arm drive scheme of first kind of drive motor on pedestal, and this retractable vehicle foot pedal comprises pedestal 1, slave arm 2, pedal support 3, pedal 4, driver train 5.

Pedestal 1 is connected with car body can multiple mode, as thread connection, welding etc., pedestal 1 is fixed on the top of this device, pedestal 1 is when design, a part of considering the arm body of slave arm 2 will intersect with pedestal 1 some places, will establish breach on the pedestal 1 and cooperate.

Slave arm 2 is processed into U type structure, its end and pedestal 1 usefulness chain pin are hinged, and the other end and pedal support 2 also use chain pin hinged, and they can rotate each other, process guide groove on slave arm 2 biside plates, the length of guide groove is consistent with the position dimension that stretcher is stretched receipts two limits.

Driver train 5 has motor 51, Rocker arm 52, rocking bar 53, motor 51 shafts connect transmission shaft, one stomidium of transmission shaft and Rocker arm 52 is fixed, again with pedestal 1 on hole A11 hinged; Rocker arm 52 other ends and rocking bar 53 usefulness bearing pins are linked together; the lower end of rocking bar 53 and pedal support 3 are hinged; because of the middle part of rocking bar 53 has transverse holes; align with the guide groove of slave arm 2 when mounted in this hole; the bearing pin of packing into; stay the 0.1mm gap between bearing pin and the groove, can be free to slide, and all adds plain bearing in each pivotally attached hole.

Pedal 4 is fixed on the pedal mounting blocks on the pedal support 3, inlays to add screw retention.

After each parts assembles mutually, regulate size, drive Rocker arm 52 by motor 51, Rocker arm 52 drives rocking bar 53, and the bearing pin of rocking bar 53 through top slides in slave arm 2 guide grooves and drive pedal support 3 and pedal 4, during work, stop when pedal 4 is stepped on the instep level when moving to, when not using, the motor counter-rotating, make slave arm 2, pedal support 3, pedal 4 withdrawals, reach safe operation.

Embodiment two, referring to Fig. 2,5,6, choose a kind of drive motor 511 and are contained in rocker-arm type of drive on the rocking bar (531), and this retractable vehicle foot pedal comprises pedestal 1, slave arm 2, pedal support 3, pedal 4, driver train 5.

Pedestal 1, pedal support 3 are identical with embodiment one, and slave arm 2 is processed into U type structure, and its end and pedestal 1 usefulness chain pin are hinged, the other end and pedal support 2 also use chain pin hinged, they can rotate each other, and a pair of through hole of processing can be provided with bearing in the through hole on slave arm 2 biside plates.

Driver train 5 is established motor 511, upper rocker arm 521, lower shake-changing arm 54, rocking bar 531, motor 51 shafts connect transmission shaft, and the mider hole of transmission shaft and rocking bar 531 adopts square opening to fix, and promptly axle, hole all are processed into square, hinged with the hole at slave arm 2 middle parts again, upper rocker arm 521 selects for use bearing pin and pedestal 1 to be hinged, and lower shake-changing arm 54 selects for use the mode of being hinged to connect with pedal support 3 equally, and upper and lower rocking arm is linked together by rocking bar 531.

After each parts assembles mutually, regulate size, drive rocking bar 531 by motor 511 and rotate, thereby upper and lower two rocking arms are rotated, make pedal support 3, pedal 4 flexible together again, because pedestal 1 is fixed on the car body, so when work, mechanism stops to stretch when pedal 4 is stepped on instep and moved to level, when not using, allow motor reverse, make slave arm 2, pedal support 3, pedal 4 withdrawals, so just can reach the work purpose.

The foregoing description is to explanation of the present invention, is not limitation of the invention, any structure after the simple transformation of the present invention is all belonged to protection scope of the present invention.
