Detailed Description

The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings for a more complete, accurate and thorough understanding of the inventive concept and technical solutions of the present invention by those skilled in the art.

As shown in fig. 1-4, the present invention provides an electric skateboard, which comprises a board body 1 and a board wheel, and further comprises a motor 3, a transmission device, connecting blocks 6 and an anti-skid board 4, wherein four connecting blocks 6 are fixed at the bottom of the board body 1 in bilateral symmetry, the board wheel comprises a driving wheel 21 and a driven wheel 22, the gear of the transmission device comprises an output gear 51, a reduction gear 52, a planetary gear 53 and a half axle gear 54, the half axle gear 54 is fixedly connected with the driving wheel 21 through a transmission shaft 55, the planetary gear 53 is fixed at one side of the reduction gear 52 through a fixing strip, the fixing strip is rotatably connected with the planetary gear 53, the two half axle gears 54 are oppositely arranged, the two planetary gears 53 are oppositely arranged, each planetary gear 53 is simultaneously engaged with the two half axle gears 54, the output gear 51 is fixedly connected with the output shaft of the motor 3, the reduction, the output gear 51 is meshed with the reduction gear 52, the transmission shaft 55 is rotatably connected with the front connecting block 6, and the two driven wheels 22 are rotatably connected with the rear connecting block 6.

The gears in the transmission are all bevel gears.

The motor 3 is fixed at the bottom of the plate body 1.

Abrasive paper is pasted on the top of the plate body 1, the antiskid plate 4 is obliquely fixed on the top of the plate body 1, the angle formed by the front side of the antiskid plate 4 and the front side of the plate body 1 is larger than 90 degrees, and the abrasive paper is pasted on the front side of the antiskid plate 4.

The bottom of the plate body 1 is fixed with a shaft bracket 7, and the shaft bracket 7 is sleeved on the output shaft.

When the electric skateboard needs to be used, if the electric skateboard needs to run straight at the moment, two feet transversely step on the top of the board body 1, the pressure distributed on the left side and the right side of the board body 1 is kept the same, after the motor 3 is electrified, the output shaft of the motor 3 drives the output gear 51 to rotate, the output gear 51 drives the reduction gear 52 meshed with the output gear to rotate, the reduction gear 52 drives the fixed strip to rotate, the fixed strip drives the planetary gear 53 to rotate around the shaft of the reduction gear 52, at the moment, the revolution of the planetary gear 53 drives the half shaft gear 54 meshed with the planetary gear to rotate, the half shaft gear 54 transmits the rotating speed to the driving wheel 21 through the transmission shaft 55, if the resistance on the driving wheels 21 on the two sides is the same, the planetary gear 53 does not rotate, if the skateboard needs to be operated to turn, the gravity center position of the skateboard needs to be adjusted to the side which wants to turn, the rotation speeds of the side gears 54 on both sides are made different, at which time the planetary gears 53 start to rotate, at which time the rotation speed output from the motor 3 is not distributed equally to the two drive wheels 21, but rather, more rotational speed is allocated to the outside drive wheel 21, a steering effect is achieved by the difference in rotational speed of the two drive wheels 21, the device can lead a skateboard fan to operate the electric skateboard to steer by arranging the transmission device, the steering work can be completed without inclining the board body 1, the safety factor when the electric skateboard is operated to steer is increased, the occurrence that the people on the board rub the ground or even fall the board due to the inclination of the board body 1 of the skateboard is reduced, the device can also make the electric skateboard step on the inclined antiskid plate 4 with the rear foot when the straight line is accelerated through the arrangement of the antiskid plate 4, and prevent accidents caused by insufficient friction force between the shoes and the surface of the board body 1 due to over-violent acceleration of the electric skateboard.
