Detailed description of the invention
According to shown in Fig. 1 to Fig. 4, a kind of pedal described in the present embodiment has 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.
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.
Shown in composition graphs 1, Fig. 5 and Fig. 6, described pedal is installed with magnet a7, described vehicle body two sides are installed with control setup 8, and control setup is corresponding with the magnet a position on the pedal of collapsed state; Described control setup comprises the housing 81 of an opening towards the groove body type of the plastic material outside vehicle body or aluminum alloy material, the opening inner side of housing is installed with the magnet b83 of annular, the bottom of housing is installed with the magnet c84 of annular, the magnetic direction of magnet b is identical with magnet a, and the magnetic direction of magnet c is contrary with magnet a; An armature 82 is slidably fitted with in housing, described armature includes pedal control part 822 that one successively connects, commutation adhesive portion 821 and damper connecting portion 823, described pedal control part passes magnet b and does not contact with magnet b inner circumferential, described commutation adhesive portion and inner walls sliding block joint, and commutation adhesive portion both ends of the surface can respectively with magnet b, the adhesive of magnet c phase; Described damper connecting portion periphery is arranged with the spring 86 of an aluminum alloy materials, and the two ends of spring are limited between commutation adhesive portion and housing bottom, and the external diameter of spring is less than the internal diameter of magnet c; One is connected with in order to slow down the straight line one-way damper 85 of spring reset speed between described damper connecting portion and the bottom of housing; When described commutation adhesive portion and magnet c phase adhesive, the outer end of described pedal control part exceeds the end face of magnet b near shell nozzle, and the repulsion between magnet a and the magnetic field of armature is greater than the suction between magnet a and armature itself.
The magnetic force of described magnet b and magnet c is 5000-6000 Gauss, the magnetic force of magnet a is 2000-3000 Gauss, when such armature and magnet b adhesive, armature can be made to have enough suction to suck pedal, and when armature and magnet c adhesive, the magnetic force of armature is enough to again to overcome the suction of itself and magnet a and is flicked by magnet a and make pedal launch.
Described damper connecting portion forms the connection recess connecting straight line one-way damper.Connect recess be beneficial to the installation of straight line one-way damper and be beneficial to the volume reducing control setup.
Distance between described magnet b and magnet c 5-15mm larger than the thickness in commutation adhesive portion.
When described spring is in extended configuration, commutation adhesive portion and the adhesive of magnet b phase of armature, because the magnetic direction of magnet b is identical with magnet a, armature is magnetized jointly by magnet b and magnet a, the magnetic direction of armature is identical with magnet a, the pedal control part of armature of electromagnet and the magnet a phase adhesive on pedal, thus make pedal be fixed on collapsed state; When needs use wheelbarrow, by hand or foot's pressing pedal, thus make pedal promote the inside indentation of armature, spring is compressed into the commutation adhesive portion of armature and the adhesive of magnet c phase, because the magnetic direction of magnet c is contrary with magnet a, commutation adhesive portion on armature and pedal control part are magnetized by magnet c and magnet a respectively, as long as the suction between armature and magnet c is greater than the suction between magnet a and armature, so, namely produce mutual exclusion between armature and magnet a, thus force pedal rotate and change to deployed condition under self gravitation effect.Described straight line one-way damper makes spring reset speed slow down, when magnet a starts to depart from armature, the time that armature contacts with magnet c is extended, thus guarantee on armature by magnet c magnetize produce magnetic field force can not disappear at once and make armature again with magnet a adhesive.
