Specific embodiment

For the ease of the understanding of those skilled in the art, in the following with reference to the drawings and specific embodiments to the utility model make into The description of one step.

As shown in Figures 1 to 5, a kind of electric return board of single motor, including car body 1 are connected with beat turning machine on car body 1 Structure and the first wheel 2, the number of the first wheel 2 are one, and the first wheel 2 is rotatably connected on car body 1, and the first wheel 2 extends The lower end of car body 1 out is connected with the second wheel 3 in beat steering mechanism, and the number of the second wheel 3 is one, the second wheel 3 to The lower end of car body 1 extends out, and the first wheel 2 and the second wheel 3 are in tandem on car body 1.It is placed on the floor this single motor When electric return board, the first wheel 2 and the second wheel 3 contact to earth, and the first wheel 2 and the second wheel 3 make somebody a mere figurehead car body 1, the first wheel 2 It is used to control movement, the turning of the electric return board of this single motor with the second wheel 3, the first wheel 2 and the second wheel 3 rotate forward When, the electric return board of this single motor is moved forward along the length direction of car body 1.

Using this single motor electric return board when, user stand on car body 1, control body give car body 1 lateral force, second Lateral rotation just occurs for wheel 3, so that the electric return board of this single motor achievees the effect that turning, after completing turning, turns in beat To under the action of mechanism, 3 self-aligning of the second wheel, so that the second wheel 3 restores preceding line direction.

Be provided on car body 1 can front and back overturn pedal 7, the reverses direction of pedal 7 is consistent with the length direction of car body 1, The angle induction device corresponding to pedal 7 is additionally provided on car body 1, angle induction device is for sense pedal 7 with respect to car body 1 Tilt angle.It further include control module 5 and battery module 52, the first wheel 2 is built-in with hub motor (not shown), control Module 5 connects angle induction device, hub motor and battery module 52, and control module 5 controls hub motor according to tilt angle Rotation.Control module 5 is used for the signal of receiving angle sensing device and is analyzed, processing formation control signal, and control wheel Hub motor carries out corresponding operation.Battery module 52 is used to power to control module 5, angle induction device and hub motor.

Using this single motor electric return board when, user's foot steps down on pedal 7, is turned over by the front and back of foot control pedal 7 Turn, realizes the control to hub motor.When pedal 7 turns forward, hub motor is rotated forward, drives the electronic of this single motor Slide plate moves forward, and the movement speed of the electric return board of this single motor can be controlled according to 7 forward leaning angle of pedal, before pedal 7 Degree of tilt is bigger, and the electric return board movement speed of this single motor is faster.When pedal 7 tilts backwards, hub motor is gradually slowed down Until braking, to achieve the effect that brake, therefore the electric return board of this single motor has strong excellent of easy to operate, playability Point.

The beat steering mechanism includes bogie 4, and the second wheel 3 is rotatably connected on bogie 4, and the second wheel 3 can It is rotated on bogie 4, bogie 4 is rotatably connected on car body 1, is provided on bogie 4 and is formed between the longitudinal direction of car body 1 The rotary shaft 41 of acute angle, bogie 4 are specifically rotatably connected in rotary shaft 41, and bogie 4 is rotated around rotary shaft 41.

Rotation hole 114 is offered on the car body 1, rotation hole 114 is oblique to be provided on car body 1, and the fixation of rotary shaft 41 is set It sets in rotation hole 114, when bogie 4 around rotary shaft 41 to side when rotating, bogie 4 drives the second wheel 3 laterally to turn It is dynamic, to realize the steering of the electric return board of this single motor.

The the first convex hull portion 111 to raise upward, the thickness of each position in the first convex hull portion 111 are formed on the car body 1 It is thin almost the same, pedal 7 can front and back the upper end in the first convex hull portion 111 is turningly set, the first wheel 2 is rotatably connected on first The lower end in convex hull portion 111 is improved whole using the upper and lower ends that the first wheel 2 and pedal 7 are separately positioned on the first convex hull portion 111 The compactedness of body structure, therefore the electric return board of this single motor is with compact-sized.The advantages of compact.

The upper end in first convex hull portion 111 is formed with rotation slot 113, and rotation slot 113 is the bar shaped that cross section is arc Slot, the lower end of pedal 7 are formed with rotation axis 71, and rotation axis 71 is columned bar shaped bar, and rotation axis 71 fits in rotation slot 113 Interior, rotation axis 71 is together with 113 face contact of rotation slot, so that pedal 7 can the front and back overturning on car body 1.Rotation slot 113 opens up In the middle position of 111 upper end of the first convex hull portion, rotation axis 71 is formed in the middle position of 7 lower end of pedal.

When user's foot is stepped down on pedal 7, gravity passes to car body 1 by rotation axis 71, due to rotation axis 71 and rotation 113 face contact of slot together, uniform force, avoid rotation axis 71 occur fracture, damage the problems such as, therefore have it is reliable and secure, Advantage durable, rotating effect is good.

First convex hull portion 111 is arc shell, and the front and rear sides in the first convex hull portion 111 are bent downwardly, improve and step on The angle overturn before and after plate 7 further reduced restriction of the first convex hull portion 111 to pedal 7, and under the first convex hull portion 111 End face is also arc, and the first wheel 2 is whole cylindrical, and the first wheel 2 fits in the lower end in convex hull portion, therefore further increases The compactedness of structure.

Finite place piece 9 is set between the pedal 7 and the first convex hull portion 111, and it is convex that pedal 7 is limited to first by locating part 9 Front and back overturning in shell portion 111.Locating part 9 can be screw, thus locating part 9 be it is removable, dismount locating part 9, conveniently step on Plate 7 is installed in the first convex hull portion 111 or disassembles from the first convex hull portion 111.At least one through-hole is offered on pedal 7 72, the orientation of the through-hole 72 on pedal 7 and the reverses direction of pedal 7 are orthogonal, and finite place piece 9 is worn in through-hole 72, limit Position part 9 is connected on car body 1 by through-hole 72, and the structure that multiple locating parts 9 limit pedals 7 further defines pedal 7 the Position in one convex hull portion 111 avoids the shaking that pedal 7 is upward in 111 upside of the first convex hull portion.

The the second convex hull portion 112 to raise upward is formed on the car body 1, the lower end in the second convex hull portion 112 is into car body 1 Recess, beat steering mechanism are arranged in the lower end in the second convex hull portion 112, further improve the compactedness of structure.

When the electric return board of the single motor is placed on the floor, the first wheel 2 can face contact on the ground, the first wheel 2 Width is stood on car body 1 in 50mm or more, user, and it is flat on car body 1 that biggish contact area is conducive to holding user Weighing apparatus.
