  • Example 1
  • With reference to that shown in FIG. 1, Example 1 provides an electric skateboard 100, comprising a remote control 101, a board body 102, a front wheel 103, a rear wheel 104, and a battery (not shown in the figures) built in the board body 102, wherein the front wheel 103 and the rear wheel 104 are rotationally provided at two ends of the board body 102 respectively, a hub motor (not shown in the figures) for driving the rear wheel 104 is provided inside the rear wheel 104, the hub motor is connected with the battery, and the hub motor is further wirelessly connected with the remote control 101. In the present Example, the hub motor is firstly connected with an electric plate, and then the electric plate is connected with the battery.
  • The hub motor is wirelessly connected with the remote control 101, and the hub motor integrates all of the power, transmission and braking means into a hub, so that the structure of the electric skateboard 100 is greatly simplified. The control over the operation of the skateboard is realized by controlling the hub motor with the wireless remote control, omitting a pressure sensor, a mounting groove, and several circuits in a conventional skateboard structure, therefore, the electric skateboard 100 has a simple structure, a low manufacturing cost, and strong reliability. The board body 102 is in a one-piece structure, with the battery being built in the board body 102, and the electric skateboard 100 has strong integrity, capability of resisting water, high reliability, and also greatly improved strength.
  • With reference to that shown in FIG. 1 to FIG. 4, the diameter of the rear wheel 104 is greater than that of the front wheel 103. In order to ensure that a lowest point of the front wheel 103 and a lowest point of the rear wheel 104 are located in the same horizontal plane, a lower board surface of the board body 102 is recessed at a position corresponding to the rear wheel 104 to form a groove 105, and the rear wheel 104 is partially located in the groove 105.
  • The hub motor is built in the rear wheel 104. The rear wheel 104 is a power wheel. In order to improve the travelling efficiency of the electric skateboard 100, a bigger power wheel is better. However, in order to ensure that a user can maintain balance while stepping on the board body 102, there should not be too large of a distance between the board body 102 and the ground. In order to solve the above problem, the rear wheel 104 with a relatively large diameter may be provided, and the rear wheel 104 is enabled to be partially embedded in the board body 102, thus not only the travelling efficiency can be ensured, but also the user can easily maintain balance. Meanwhile, in order to facilitate the user operating the electric skateboard 100 to slide, the front wheel 103 and the rear wheel 104 cannot be simultaneously provided in a partial embedding mode, therefore, the rear wheel 104 is provided in a partial embedding mode, the front wheel 103 is not provided in an embedding mode, and the rear wheel 104 is provided below the board body 102.
  • In order to make the board body 102 in a horizontal state, and enable the user to slide steadily, it is best to ensure that the lowest point of the front wheel 103 and the lowest point of the rear wheel 104 are located in the same horizontal plane. On the basis of the above solution, it is best for the diameter of the rear wheel 104 to be greater than that of the front wheel 103. Since the thickness of the board body 102 is limited, the diameter of the rear wheel 104 cannot be too large, therefore, integrating all the above various factors, the diameter of the rear wheel 104 is preferably 12-14 cm, and the diameter of the front wheel 103 is preferably 8-12 cm.
  • With reference to that shown in FIG. 1 and FIG. 2, the front wheel 103 is connected with the lower board surface of the board body 102 through a first bracket 106, one end of the first bracket 106 connected with the lower board surface is rotatable, and the rotatable end of the first bracket is provided with a limiting member for limiting rotating amplitude of the first bracket. The rear wheel 104 is connected with the lower board surface of the board body 102 through a second bracket 107, the second bracket 107 specifically comprises two support plates provided oppositely, and the rear wheel 104 is set up between the two support plates.
  • The first bracket 106 is used to connect the front wheel 103 and the board body 102. The first bracket 106 is rotatable, (i.e. can drive the front wheel 103 to rotate along a circumferential direction of the first bracket 106), to indirectly realize rotation of the front wheel 103, and an advancing direction of the skateboard can be changed at will. Specifically, the rotation of the first bracket 106 is realized by providing a bearing between the first bracket 106 and the board body 102, facilitating control over a direction of the electric skateboard 100, and improving flexibility of selecting the advancing direction of the electric skateboard 100. If the rotating amplitude of the front wheel 103 is too large, it is difficult for the user to control the advancing direction, and user's safety will be threatened, therefore, the limiting member needs to be provided for limiting the rotating amplitude of the first bracket 106. The rotating amplitude of the first bracket 106 is usually limited by the limiting member to be 90°.
  • The second bracket 107 is used to connect the rear wheel 104 and the board body 102. The second bracket 107 comprises two support plates provided oppositely. Under the limiting effect of the support plates on the rear wheel 104, the stability of the rear wheel 104 during the rotation may be ensured. The stability of the rear wheel 104, as the power wheel, is quite important, and can ensure normal and steady sliding of the electric skateboard 100.
  • With reference to that shown in FIG. 5, an upper board surface of the board body 102 has a curved surface recessed downwards along a central axis of the board body, facilitating the user steadily standing on the board body 102.
  • With reference to that shown in FIG. 1 to FIG. 4, the board body 102 is provided with two hand-lifting holes 108, and the two hand-lifting holes 108 are symmetrical to each other with respect to the central axis of the board body 102. With the board body 102 being provided with the hand-lifting holes 108, the weight of the board body 102 can be reduced, and the hand-lifting holes 108 also can serve a decorative function; the user can lift the electric skateboard 100 using the hand-lifting holes 108, so that the electric skateboard 100 has better portability. Besides, the lower board surface of the board body 102 also can be provided with a handle so that it is easy to carry, hold and support the electric skateboard 100.
  • With reference to that shown in FIG. 1 and FIG. 3, the board body 102 partially protrudes to form anti-skid patterns 109, and the anti-skid patterns 109 can increase frictional force to a maximum degree, ensuring that the user will not skid when stepping on the board body 102. With reference to that shown in FIG. 5 and FIG. 6, a rear side surface of the board body 102 is provided with a wear-resisting rubber part 110. When the electric skateboard 100 is erected, the rubber part 110 is in contact with the ground, and no skid will occur, moreover, the rubber part 110 has a cushion effect and will not damage the electric skateboard 100 or the ground. Front and rear side surfaces of the board body 102 are provided with light reflective members 111 or light emitting members. The light reflective members 111 are embodied as light reflective plates or light reflective stickers. When the user rides the electric skateboard 100 at night, the light reflective members 111 or the light emitting members can ensure the riding safety.
  • With reference to that shown in FIG. 4, the board body 102 can be designed to have the front side surface in a circular arc shape. Such design can reduce air resistance received by the electric skateboard 100 during sliding, and when bumping into the pedestrian, the injury also will be greatly reduced. The lower board surface of the board body 102 comprises a bottom plate 112 and two inclined plates 113. Two sides of the bottom plate 112 each are connected with one inclined plate 113. Both the front wheel 103 and the rear wheel 104 are provided below the bottom plate 112. The lower board surface of the board body 102 is not in a common flat plate structure, but in a bulge structure, and such bulge structure makes lines of the board body 102 more mellow, which also can reduce the air resistance received by the electric skateboard 100 during sliding; moreover, edges of the inclined plates 113 protrude to form wear-resisting strips, which can reduce direct wear of obstacles to the electric skateboard 100 during sliding.
  • Example 2
  • With reference to that shown in FIG. 7, Example 2 provides an electric skateboard 100 a, comprising a remote control 101, a board body 102, a front wheel 103, a rear wheel 104, and a battery (not shown in the figures) built in the board body 102, wherein the front wheel 103 and the rear wheel 104 are rotationally provided at two ends of the board body 102 respectively, a hub motor (not shown in the figures) for driving the rear wheel 104 is provided inside the rear wheel 104, the hub motor is connected with the battery, and the hub motor is further wirelessly connected with the remote control 101. Preferably, the board body 102 has a length of 85 cm, a width of 21 cm, and a thickness of 14 cm. The specification of the board body 102, which is the same as the specification of a board body of a common skateboard, is a universal specification.
  • The hub motor is wirelessly connected with the remote control 101. The hub motor integrates all of the power, transmission and braking means into a hub, so that the structure of the electric skateboard 100 a is greatly simplified. The control over the operation of the skateboard is realized by controlling the hub motor through the wireless remote control, omitting a pressure sensor, a mounting groove, and several circuits in a conventional skateboard structure, therefore, the electric skateboard 100 a has a simple structure, a low manufacturing cost, and strong reliability. The board body 102 is in a one-piece structure, the battery is built in the board body 102, and the electric skateboard 100 a has strong integrity, capability of resisting water, high reliability, and also greatly improved strength.
  • With reference to that shown in FIG. 7 and FIG. 8, the diameter of the front wheel 103 is equal to that of the rear wheel 104. The front wheel 103 is connected with a lower board surface of the board body 102 through a first bracket 106, one end of the first bracket 106 connected with the lower board surface is rotatable, and the rotatable end of the first bracket is provided with a limiting member for limiting rotating amplitude of the first bracket. Specifically, rotation of the first bracket 106 is realized by providing a bearing between the first bracket 106 and the board body 102, facilitating control over a direction of the electric skateboard 100, and improving flexibility of selecting an advancing direction of the electric skateboard 100. The rear wheel 104 is connected with the lower board surface of the board body 102 through a second bracket 107.
  • In order to ensure the board body 102 to be horizontal, the front wheel 103 provided below the board body 102 should have the diameter equal to the diameter of the rear wheel 104. The hub motor is built inside the rear wheel 104. The rear wheel 104 is a power wheel. In order to improve the travelling efficiency of the electric skateboard 100, a bigger power wheel is better. However, in order to ensure that the user can maintain balance while stepping on the board body 102, there should not be too large of a distance between the board body 102 and the ground, that is, the rear wheel 104 should not be too big, and upon comprehensive consideration, the diameter of the rear wheel 104 is preferably 12.5 cm.
  • With reference to that shown in FIG. 9, the battery is a rechargeable battery, the rear side surface is provided with a charge port connected with the rechargeable battery, and the charge port is provided with a rubber plug 114. The rechargeable battery is provided, so that the electric skateboard 100 a becomes more convenient and has a wider application range, and that the user is able to perform charging at any time as required; the charge port is provided with the rubber plug 114, so as to ensure good sealability of the interior of the board body 102 when the electric skateboard 100 a is in a non-charging state, and prevent water and dust from entering the interior of the board body 102.
  • With reference to that shown in FIG. 7 and FIG. 8, the board body 102 is provided with two hand-lifting holes 108, and the two hand-lifting holes 108 are symmetrical to each other with respect to a central axis of the board body 102. With the board body 102 being provided with the hand-lifting holes 108, the weight of the board body 102 can be reduced, and the hand-lifting holes 108 can also serve a decorative function; the user can lift the electric skateboard 100 a using the hand-lifting holes 108, so that the electric skateboard 100 a has better portability. Besides, a lower board surface of the board body 102 can also be provided with a handle so that it is easy to carry, hold and support the electric skateboard 100 a.
  • With reference to that shown in FIG. 7 and FIG. 9, the board body 102 partially protrudes to form anti-skid patterns 109, and the anti-skid patterns 109 can increase frictional force to a maximum degree, ensuring that the user will not skid when stepping on the board body 102. A rear side surface of the board body 102 is provided with a wear-resisting rubber part 110. When the electric skateboard 100 a is erected, the rubber part 110 is in contact with the ground, and no skid will occur, moreover, the rubber part 110 has a cushion effect and will not damage the electric skateboard 100 a or the ground. Side surfaces of the board body 102 are provided with light reflective members 111 for ensuring riding safety at night.
  • Example 3
  • With reference to that shown in FIG. 10, Example 3 provides an electric skateboard 300, whose structure is substantially the same as the electric skateboard 100 provided in Example 1, and which comprises a remote control 101, a board body 102, a front wheel 103, a rear wheel 104, and a battery (not shown in the figures) built in the board body 102, wherein the front wheel 103 and the rear wheel 104 are rotationally provided at two ends of the board body 102 respectively, a hub motor (not shown in the figures) for driving the rear wheel 104 is provided inside the rear wheel 104, the hub motor is connected with the battery, and the hub motor is further wirelessly connected with the remote control 101. In the present example, the hub motor is firstly connected with an electric plate, and then the electric plate is connected with the battery.
  • The embodiment of FIG. 10 differs from the other described embodiments at least because the board body 102 is in a step-like shape, and a middle section of the board body 102 is lower than the two ends. When a user stands on the middle section, the relatively short distance to the ground facilitates the user maintaining steadiness during sliding, and the relatively long distances from the two ends of the board body 102 to the ground may make the front wheel 103 and the rear wheel 104 have a relatively large diameter, ensuring the travelling efficiency.
  • The above description is intended to be illustrative, not restrictive. The scope of the invention should be determined with reference to the appended claims along with the full scope of equivalents. It is anticipated and intended that future developments will occur in the art, and that the disclosed devices, kits and methods will be incorporated into such future embodiments.
