[0022] Embodiment 1

[0023] Refer to Figure 1, an electric roller skating device in this embodiment includes an electric roller skate 1 and a non-electric roller skate 2. The electric roller skate 1 and the non-electric roller skate 2 are respectively worn on the user's right foot and left foot. Of course, according to the user's usage habit, the electric roller skate 1 can also be worn on the user's left foot, and the non-electric roller skate 2 is correspondingly worn on the user's right foot. The user can support on the ground through the electric roller skate 1 and the non-electric roller skate 2, and the non-electric roller skate 2 can be driven by the electric roller skate 1, so that the user moves relative to the ground. This electric roller skating device can not only be used as a sports and leisure device, but also as a means of transportation for short-distance travel. Compared with an electric scooter, this electric roller skating device can be worn on the user's feet, and its volume and weight are significantly smaller, which is beneficial for the user to carry around.

[0024] Of course, in other embodiments, the electric roller skating device can also include two electric roller skates 1, that is, both the user's left foot and right foot are worn with electric roller skates 1. This increases the entertainment and fun.

[0025] Refer to Figure 1 and Figure 2 , an electric roller skate 1 includes a shoe body 3, two wheels 4 arranged on the shoe body 3, a motor 5 and a battery 6. Compared with ordinary shoes in the market, the shoe body 3 is mainly used to accommodate the user's heel part, that is, the front part of the foot can be exposed outside the shoe body 3. When the user's heel part is worn on the electric roller skate 1, the front part of the foot can be separated from the ground or supported on the ground. Of course, the shoe body 3 can also be designed into a structure that accommodates the entire foot of the user. The two wheels 4 are connected by a wheel axle 7 and are respectively located on the left and right sides of the shoe body. The battery 6 is electrically connected to the motor 5, and the motor 5 is connected to the wheel axle 7 through a transmission mechanism 8. The motor 5 is connected to the wheel axle 7 and drives the two wheels 4 to rotate coaxially with the wheel axle 7. The electric roller skate 1 can realize the movement of the user through the rotation of the two wheels 4. Compared with ordinary roller skates in the prior art, this electric roller skate 1 can be driven by electricity to save the user's physical strength and can realize the function of short-distance transportation. Compared with an electric scooter or the smallest electric vehicle, the electric roller skate 1 can be worn on the user's feet, and its volume and weight are significantly smaller, which is beneficial for the user to carry around.

[0026] Refer to Figure 2 and Figure 3, the shoe body 3 includes a first split body 31 and a second split body 32 that can vary in distance relative to the first split body 31. The first split body 31 includes a heel support plate 311, a left side panel 312 connected to the heel support plate 311, a motor mounting portion 313 provided at the rear side of the heel support plate 311, and a transmission member mounting portion 314 provided outside the motor mounting portion 313 and the left side panel 312. The motor mounting portion 313 is fixedly connected to the rear end of the left side panel 312, which can improve the overall structural firmness of the shoe body 3. The outer edge of the motor mounting portion 313 located at the rear side of the user's heel can also serve as the rear side panel of the shoe body 3. The motor 5 is mounted inside the motor mounting portion 313. The motor 5 is a single-sided output shaft reduction motor, and its motor output shaft penetrates through the left end face of the motor mounting portion 313 and extends outward to be connected to the transmission mechanism 8. A battery mounting hole 317 is provided on the right side of the motor mounting portion 313, and the battery 6 is detachably connected to the motor mounting portion 313, which is convenient for replacing the battery. The battery 6 is a rechargeable battery or a dry battery. Of course, the battery 6 can also be mounted at other positions of the shoe body 3 according to design requirements, for example: below or inside the heel support plate 311. The transmission member mounting portion 314 is located on the left side of the shoe body 3 and is provided with a hollow cavity for mounting the transmission mechanism 8. The transmission member mounting portion 314 is connected with a first cover plate 315 to cover the hollow cavity. The front end of the first cover plate 315 extends to the mounting position of the wheel 4. The upper end of the left side panel 312 is bent towards the first cover plate 315, and the bent portion at least covers a part of the wheel 4 on the left side of the shoe body. The heel support plate 311 is provided with a hollow cavity, and a fixed sleeve 316 for mounting the wheel shaft 7 is connected inside the hollow cavity. The wheel shaft 7 is rotatably connected to the fixed sleeve 316. The wheel shaft 7 connected to the transmission mechanism 8 penetrates through the fixed sleeve 316 of the heel support plate 311 and extends towards the second split body 32.

[0027] The second split body 32 includes a sliding body 321 that can be slidably connected to the heel support plate 311, a right side panel 322 connected to the sliding body 321, and a second cover plate 323 connected to the outside of the right side panel 322. The sliding body 321 extends into the hollow cavity of the heel support plate 311. The upper end of the right side panel 322 is bent towards the second cover plate 323, and the bent portion at least covers a part of the wheel 4 on the right side of the shoe body.

[0028] Refer to Figure 2 and Figure 4, the wheel axle 7 includes a first shaft body 71 and a second shaft body 72 that can axially vary the distance relative to the first shaft body 71. The first shaft body 71 is provided with an axial sliding groove, and the second shaft body 72 is provided with a sliding block that cooperates with the sliding groove. The first shaft body 71 and the second shaft body 72 can only slide relative to each other axially and cannot rotate relative to each other. The transmission mechanism 8 can drive the first shaft body 71 and the second shaft body 72 to rotate in the same direction together. The first shaft body 71 is connected to the first split body 31 through a bearing 9, and the second shaft body 72 is connected to the second split body 32 through a bearing 9. The sliding block of the second shaft body 72 extends into the sliding groove of the first shaft body 71, and the user manually adjusts the position of the sliding block relative to the sliding groove so that the first shaft body 71 and the second shaft body 72 slide relative to each other in the left-right direction to adjust the relative distance between the first split body 31 and the second split body 32. The sliding body 321 slides relative to the heel support plate 311 following the second split body 32. Reducing or increasing the relative distance between the first split body 31 and the second split body 32 can improve the adaptability of the electric roller skates 1 to accommodate users of different body types. It should be noted that when the user uses the electric roller skates 1, the user can directly wear the electric roller skates 1 when already wearing shoes; of course, the user can also wear the electric roller skates 1 when barefoot or only wearing socks, which is simple and practical and can be applied to indoor or outdoor use scenarios. A fastening member (not shown in the figure) is provided between the first shaft body 71 and the second shaft body 72. Adjusting the fastening member can make the first shaft body 71 and the second shaft body 72 relatively fixed and maintain the currently adjusted relative sliding position, improving the adaptability when the user wears the shoe body. A shoelace 10 is connected between the left side plate 312 of the first split body 31 and the right side plate 322 of the second split body 32, and the shoelace 10 is located above the user's instep. One end of the shoelace 10 is fixedly connected to the left side plate 312, and the other end is detachably connected to the right side plate 322. Fixing the two ends of the shoelace 10 to the left side plate 312 and the right side plate 322 respectively can prevent the user's foot from detaching from the electric roller skates 1 and improve the firmness when the user wears the shoe body.

[0029] Refer to Figures 1 to 4, the heel part of the user steps on the upper side of the heel support plate 311 of the shoe body 3, and the user's sole is exposed outside the shoe body 3, that is, the front end of the shoe body 3 is behind the user's sole. The left side plate 312 and the right side plate 322 are oppositely arranged and are respectively located on the left and right sides of the user's heel. The relatively inner end faces of the left side plate 312 and the right side plate 322 are provided with anti-slip lines 11 to prevent the user's foot from sliding relative to the shoe body 3. A cavity for accommodating the foot is formed between the first split body 31 and the second split body 32. The first shaft body 71 of the wheel axle 7 protrudes from the left side plate 312 and is connected to the first cover plate 315 through a bearing 9. The wheel 4 on the left side of the shoe body is fixedly connected to the first shaft body 71 and is located between the left side plate 312 and the first cover plate 315. The second shaft body 72 of the wheel axle 7 protrudes from the right side plate 322 and is connected to the second cover plate 323 through a bearing 9. The wheel 4 on the right side of the shoe body is fixedly connected to the second shaft body 72 and is located between the right side plate 322 and the second cover plate 323. The wheel axle 7 can not only be used to install the two wheels 4, but also serve as a transmission mechanism 8 to drive the two wheels 4 to rotate as a transmission shaft; in addition, the first shaft body 71 and the second shaft body 72 of the wheel axle 7 can also slide axially relative to each other to adjust the relative distance between the first split body 31 and the second split body 32. The two wheels 4 on the left and right sides of the shoe body rotate in the same direction following the wheel axle 7 and drive the electric roller skates to move. Of course, in other embodiments, rollers can also be added to the front part and / or the rear part of the shoe body 3, and the rollers cooperate with the two wheels 4 to jointly support the shoe body 3 and can follow the two wheels 4. The sizes of the two wheels 4 are the same.

[0030] Refer to Figure 2 , in this embodiment, the transmission mechanism 8 includes a first pulley 81 connected to the motor output shaft, a second pulley 82 connected to the wheel axle 7, and a transmission belt 83 connecting the first pulley 81 and the second pulley 82. The first pulley 81 is fixedly installed on the motor output shaft of the motor 5, and the second pulley 82 is fixedly installed on the first shaft body 71 of the wheel axle 7. The second pulley 82 is located between the wheel 4 on the left side of the shoe body and the first cover plate 315. Of course, a tension pulley (not shown in the figure) can also be installed on the transmission part installation part 314, and the tension pulley abuts against the side of the transmission belt. Adjusting the position of the tension pulley can increase the tension of the transmission belt. The transmission belt 83 is a synchronous belt, a V-belt or a flat belt. The transmission mechanism 8 is installed in the hollow cavity of the transmission part installation part 314 of the first split body 31, and the first cover plate 315 can prevent the transmission belt 83 from colliding with external objects. The belt drive structure has the advantages of stable transmission, simple structure, low cost, and convenient use and maintenance.

[0031] Of course, in other embodiments, the transmission mechanism can also be a gear transmission structure. The gear transmission structure includes a first gear connected to the output shaft of the motor and a second gear connected to the wheel axle. The first gear and the second gear are in meshing transmission. The first gear and the second gear are spur gears or bevel gears. Of course, a third gear can also be provided between the first gear and the second gear; alternatively, a transmission rod is connected between the first gear and the second gear, the first gear and the second gear are bevel gears, and bevel gears meshing with the first gear and the second gear are respectively provided at both ends of the transmission rod.

[0032] Of course, in other embodiments, as Figure 5 shown, the transmission mechanism can also be a link mechanism. The link mechanism includes a turntable 12 connected to the output shaft of the motor, and a link 13 connecting the turntable 12 and the wheel 4. A first rotating shaft is provided on the turntable 12, and a second rotating shaft is provided on the wheel 4. Both ends of the link 13 are rotatably connected to the first rotating shaft and the second rotating shaft respectively. The length of the link 13 is equal to the axial distance between the output shaft of the motor and the wheel 4, and the distance from the axis of the first rotating shaft to the axis of the output shaft of the motor is equal to the distance from the axis of the second rotating shaft to the axis of the wheel axle.

[0033] In this embodiment, the difference between the non-electric roller skates 2 and the electric roller skates 1 is that the non-electric roller skates 2 are not provided with a motor 5, a battery 6 and a transmission mechanism 8. The connection relationship between its components can refer to the connection relationship of the corresponding components in the electric roller skates 1, and will not be repeated here.

[0034] In this embodiment, when the user wears the electric roller skates 1 and the non-electric roller skates 2 and is about to use them, the left and right feet are straddled forward and backward, and the electric roller skates 1 and the non-electric roller skates 2 are arranged front and back respectively; the power switch of the electric roller skates 1 is turned on, and the motor 5 drives the two wheels 4 to rotate through the transmission mechanism 8; the fronts of both feet of the user are kept separated from the ground, the two wheels 4 of the electric roller skates 1 are in contact with the ground and generate friction with the ground to push the electric roller skates 1 to move, and the two wheels 4 of the non-electric roller skates 2 are also in contact with the ground; the non-electric roller skates 2 are driven by the electric roller skates 1, and thus the user can realize the movement control of the electric roller skating equipment. In addition, when the front part of the foot wearing the electric roller skates 1 supports on the ground, the friction generated between the front part of the foot and the ground can make the user temporarily stop moving, playing a role of short-term braking. Of course, the user can also stop moving by turning off the power switch of the electric roller skates 1 to stop the motor from rotating.

[0035] Of course, in other embodiments, the user grasps an operating controller for sending a remote control signal. A signal receiving module for receiving a remote control signal is disposed on the shoe body 3 of the electric roller skate 1. The signal receiving module is signal-connected to the operating controller and can be signal-connected in a wired or wireless manner. The remote control signal may include control commands for power on / off, acceleration, deceleration, forward movement, and backward movement. The operating controller may be a remote control or a mobile terminal installed with corresponding programs.

[0036] Embodiment 2

[0037] The difference between this embodiment and Embodiment 1 is that the two wheels installed on the shoe body are hub motor wheels.

[0038] In this embodiment, the electric roller skate includes a shoe body, hub motor wheels respectively disposed on the left and right sides of the shoe body, and a battery disposed on the shoe body. The battery is connected to the two hub motor wheels and provides working power. The two hub motor wheels are respectively independently disposed on the left and right sides of the shoe body. Of course, the two hub motor wheels may also be connected by a wheel axle, and the two hub motor wheels are respectively located at both ends of the wheel axle.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention; therefore, although the present specification has described the present invention in detail with reference to the above embodiments, those of ordinary skill in the art should understand that the present invention can still be modified or equivalently replaced; and all technical solutions and their improvements that do not depart from the spirit and scope of the present invention shall be covered by the scope of the claims of the present invention.
