Detailed description of the invention
According to shown in Fig. 1 to Fig. 4, a kind of pedal described in the present embodiment, with the self-balancing wheelbarrow of auxiliary wheel, includes vehicle body 1, is fixedly mounted on two pedal mounting rods 2 vertically arranged of vehicle body both sides, and is arranged on two pedals 4 of vehicle body both sides; Pedal mounting rod upper end is fixedly connected with the axis of wheelbarrow motor, is provided with auxiliary wheel 41 below described pedal, and described two pedal mounting rod in the vertical directions slidably connect sliding shoe 3, and described pedal is rotatably connected on sliding shoe by adapter shaft 43; Described pedal mounting rod 2 top is connected with drive screw 5 by bearing, drive screw and a driver module 6 be arranged in vehicle body are in transmission connection, and described sliding shoe forms towards the one side of pedal mounting rod the motion thread 32 coordinating with drive screw and be in transmission connection; All be provided with to detect user foot above described two pedals and whether step down in sensor 42 on pedal, described sensor and driver module are electrically connected with controller.
Described sensor is pressure sensor, and also usable contact button switch substitutes.
Described driver module is stepping motor, and the output shaft of stepping motor is coaxially connected with drive screw.
Described pedal mounting rod vertically forms two dovetail furrows, described sliding shoe forms the swallow tail 31 with described dovetail furrow sliding connection; Described pedal mounting rod forms the arc-shaped concave holding described drive screw in the one side of sliding shoe between two dovetail furrows.Described sliding shoe bottom forms the pedal connecting bore 33 passed for adapter shaft.
The below of described pedal is provided with two auxiliary wheels, and two auxiliary wheels are arranged along isoplanar, tread length direction.
When on the foot of user does not step on pedal or when only having a pin to step on pedal, sliding shoe is positioned at the position, bottom of pedal mounting rod, at this moment the auxiliary wheel lower surface below pedal is concordant with the wheel lower surface of wheelbarrow, like this when starting to ride, when only having a pin to step down on a pedal, the pressure that the side of vehicle body produces user's shank is less, even beginner's shank also not easily to extrude and injured because produce with vehicle body side, after two pin of user are all stepped on pedal, sensor on two pedals detects that two pedals are all trampled, then controller control step motor drives drive screw to rotate, thus two pedals are upwards risen along pedal mounting rod simultaneously, when stopping, user can to stand on tiptoe point by a pin, sole is made to cancel pressure to sensor, then controller control pedal moves down, to auxiliary wheel and earth surface, can stop reposefully like this.
After digging pedal in addition, the medial surface 40 of pedal is downward, and concordant with the lower surface of wheel, just can erectly place on the ground when such wheelbarrow does not use.
Shown in composition graphs 1, Fig. 5, Fig. 6 and Fig. 7, described pedal is installed with magnet a8, described vehicle body two sides are installed with control setup 7, and control setup is corresponding with the magnet a position on the pedal of collapsed state; Described control setup comprises the plastic material of an opening towards the strip shape outside vehicle body or the housing 71 of aluminum alloy material, in housing, the bottom relative with opening is installed with the magnet c73 of magnet b72 and annular, the magnetic direction of magnet b is identical with the magnetic direction of the magnet a on the pedal of collapsed state, and the magnetic direction of the magnet a on the magnetic direction of magnet c and the pedal of collapsed state is contrary; Described housing internal fixtion is connected with the circular joint pin 75 vertical with magnet b magnetic direction, and joint pin is positioned at the position of housing near opening; On described joint pin, fixed cover is connected to a rotary damper 76, and on rotary damper, fixed cover is connected to the armature 74 of a strip shape, and the housing bottom position be positioned within magnet c is connected with the spring 77 of a non-magnetic material; Described armature is relative with magnet c and one side that is that be connected with spring is the 4th wall 744, the wall that described armature is relative with magnet b and adjacent with the 4th wall is the 3rd wall 743, between 3rd wall and the 4th wall in obtuse angle, the wall that described armature is relative with the 4th wall is the first wall 741, first wall is parallel with the 3rd wall, the wall that described armature is relative with the 3rd wall is the second wall 742, second wall parallels with the 4th wall, and described first wall and the second wall crossover position are in the one end near magnet c; Attractive force when described magnet c and armature adhesive is less than the thrust of spring.
Just because described first wall and the second wall crossover position are in the one end near magnet c, armature just can be made to produce rotation so magnet a oppresses armature.
When described spring is in extended configuration, the 3rd connecting wall of armature and magnet b adhesive, the first wall and magnet a also phase adhesive.Namely pedal can be fixed on control setup by magnet a, when needs use wheelbarrow, turn on the power switch, sliding shoe moves up 1-2cm under control of the controller automatically, make pedal away from ground, then by foot or hand pressing pedal, the easiest mode gently plays pedal with pin, thus make magnet a oppress the first wall position of armature, thus armature is rotated, and then Compress Spring, to the 4th wall during end position and magnet c adhesive, magnet a is then affixed with the second wall, now armature due to magnet c adhesive, magnetic field and the magnet a of armature are reverse, after unclamping the compressing to pedal, pedal is in deployed condition because magnetic field repulsive force effect just can rotate.Described armature can produce reset under the action of the spring, the speed that described rotary damper resets in order to the armature that slows down, thus avoids armature reset rapidly and again hold magnet a.
Owing to being make pedal fall by carrying out pressing to pedal bottom surface during expansion pedal, the bottom surface of pedal can not be subject to the pollution of sole dirt, namely uses hand to carry out operating also comparatively health.
The on-off model that described controller is obtained by receiving sensor, thus the using state judging wheelbarrow, thus the movement controlling sliding shoe, the control program of controller is the prior art that those skilled in the art easily realize, and is again not described in detail.
