The utility model adopts the technical proposal that:

the utility model provides a but automatically regulated's running-board, includes horizontal motor, vertical motor, running-board, driving medium, universal joint, bearing assembly, torsion bar and lifter, horizontal motor connects the driving medium, and universal joint one end is connected to the driving medium, and the torsion bar is connected to the universal joint other end, and the torsion bar middle part is provided with the recess and the recess bottom surface is connected the outer lane of bearing assembly, and the lifter is connected to the bearing assembly inner circle, and the lifter is connected vertical motor, and vertical motor is used for driving the lifter to move vertically, and the lifter can drive bearing assembly and torsion bar and move vertically, and bearing assembly can make the relative lifter rotary motion of torsion bar. The screw rod nut is sleeved with the bearing assembly, the screw rod is connected with the torsion rod through the bearing assembly, the torsion rod can do rotary motion relative to the screw rod and cannot drive the screw rod nut to rotate, and the torsion rod is driven to vertically move on the screw rod through the screw rod nut.

Preferably, the lifting rod comprises a screw rod, a screw nut and a nut connecting piece, the vertical motor is meshed with the screw rod, the screw rod is meshed with the inner side of the screw nut, the nut connecting piece is meshed with the outer side of the screw nut, and the upper portion of the nut connecting piece is connected with the torsion bar. The nut connecting piece is used for supporting the torsion bar, and the screw nut can drive the nut connecting piece to rotate when rotating, so that the nut connecting piece rises or falls along with the screw nut, and the torsion bar is driven to rise or fall.

Preferably, the transmission part comprises a horizontally arranged worm and a horizontally arranged worm wheel, the worm is coaxially connected with the horizontal motor, and the worm wheel is fixedly connected with the universal joint.

Compared with the prior art, the utility model have following advantage and effect:

1. the utility model discloses a set up and cup joint bearing assembly on screw nut, utilize bearing assembly with lead screw and torsion bar connection, it is rotatory that the realization torsion bar can make rotary motion and can not drive screw nut relative to the lead screw to the realization drives the vertical motion of torsion bar on the lead screw through screw nut.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Example 1: as shown in fig. 1 to 3, this embodiment is an automatically adjustable pedal, which comprises a horizontal motor 1, two vertical motors 2, a pedal 3, a worm wheel 4, a worm 5, two cross universal joints 6, two bearing assemblies 7, two torsion bars, two lead screws 12, two lead screw nuts 10 and two nut connectors 11, wherein the torsion bars are composed of a front torsion bar 8 and a rear torsion bar 9, the horizontal motor 1 is coaxially connected with the worm 5, the worm 5 is engaged with the horizontally arranged worm wheel 4, the bottom of the worm wheel 6 is fixedly connected with one end of the cross universal joint 6, the other end of the cross universal joint 6 is connected with the front torsion bar 8, the middle parts of the front torsion bar 8 and the rear torsion bar 9 are provided with grooves and connected with the outer ring of the bearing assembly 7, the rear end of the front torsion bar 8 is fixedly connected with the front end of the rear torsion bar 9, the inner ring of the bearing assembly 7 is connected, the bottom of the screw nut is meshed with a nut connecting piece 11, the top of the nut connecting piece 11 is contacted with a rear torsion bar 9 and a front torsion bar 8, a screw 12 is connected with a vertical motor 2, similarly, one end of another cross universal joint 6 is connected with the front torsion bar 8, the middle parts of the front torsion bar 8 and the rear torsion bar 9 are both provided with grooves, the bottom surfaces of the grooves are connected with the outer ring of a bearing assembly 7, the rear end of the front torsion bar 8 is fixedly connected with the front end of the rear torsion bar 9, the inner ring of the bearing assembly 7 is connected with a screw nut 10, the screw nut 10 is meshed with the screw 12, the bottom of the screw nut is meshed with the nut connecting piece 11, the top of the nut connecting piece 11.

In the operation process, when the pedal 3 needs to be horizontally rotated, the horizontal motor 1 works to drive the turbine 4 to rotate, the arrangement of the cross universal joint 6 and the bearing assembly 7 allows the front torsion bar 8 and the rear torsion bar 9 to rotate, and the pedal 3 is further rotated to a proper position; when the pedal 3 needs to be lifted, the two vertical motors 2 work simultaneously, the screw rod 12 rotates, the screw rod nut 10 lifts, the nut connecting piece 11 is driven to lift, and then the rear torsion bar 9 and the front torsion bar 8 are driven to lift, and due to the arrangement of the bearing assembly 7, the rear torsion bar 9 and the front torsion bar 8 cannot rotate when lifting, and then the pedal 3 is lifted to a proper height.
