The plurality of loading spaces 311 has a width corresponding to the width W of the main body no of the personal mobility 100, and in the plurality of loading spaces 311, the personal mobility 100 may be continuously stacked in the up-down direction or the front-rear direction.
[0069] The plurality of loading spaces 311 is partitioned by a plurality of partition walls 312 installed inside the loading rack 310. The plurality of partition walls 312 may be spaced apart from each other at equal intervals in the lateral direction and may extend in the up-down direction and the front-rear direction.
[0070] As illustrated in
[0071] The main body 110 of the personal mobility loaded in the loading space 311 may be stably supported without falling down because opposite sides thereof are supported by the partition wall 312 or a side wall 313 of the loading rack 310. Also, the front wheel 120 and the rear wheel 130 of the personal mobility 100 loaded on an upper side in the loading space 311 are supported in a state of being partially accommodated in the wheel receiving grooves 117 and 118 of the lower personal mobility body 110, the upper personal mobility 100 may be stably loaded without being pushed in the front-rear direction.
[0072] As illustrated in
[0073] The coupling bars 320 may be easily mounted by a method in which the coupling bars 320 are inserted from a side of the loading rack 310 in a state in which one or more personal mobilities 100 are loaded inside the loading rack 310. The plurality of personal mobilities 100 inside the loading space 311 may be fixed so as not to be pushed in the front-rear direction and the up-down direction by the coupling bars 320.

[0076] When the loading apparatus 300 is mounted on a transport truck, the user may load or unload the personal mobility 100 onto or from the loading rack 310 using a lifting device or the like installed in the transport truck. A worker who collects and relocates the personal mobility 100 may easily couple or uncouple the plurality of loaded personal mobilities 100 by mounting or removing the one or more coupling bars 320 to or from the side of the loading rack 310.
[0077]
[0078] As illustrated in
[0079] The personal mobility 200 according to the second embodiment may include a front wheel support device 270 installed in the front wheel receiving portion 213 to support the front wheel 220 and capable of moving the front wheel 220 to the inside of the front wheel receiving portion 213 or the outside of the main body 210, and a rear wheel support device 280 installed in the rear wheel receiving portion 214 to support the rear wheel 230 and capable of moving the rear wheel 230 to the inside of the rear wheel receiving portion 214 or the outside of the main body 210.
[0080] Referring to
[0081] The front wheel support member 271 is provided in a fork shape to support a shaft of the front wheel 220 and includes a first support shaft 271a connected to a power transmission device 260 of a steering device on an upper side thereof.
[0082] The shaft support member 272 rotatably supports the first support shaft 271a so that the front wheel support member 271 may rotate in a steering direction. The second support shaft 273 extends in a width direction of the main body 210 from opposite sides of the shaft support member 272 to be rotatably supported on the main body 210. Accordingly, the front wheel support member 271 may rotate about the first support shaft 271a for steering of the front wheel 220, or may rotate about the second support shaft 273 for the turning movement of the front wheel 220.
[0083] The front transfer driving device 274 may rotate the second support shaft 273 in the forward or backward direction to move the front wheel 220 to the outside of the main body 210 or the inside of the main body 210. As illustrated in
[0084] Because the front transfer driving device 274 employs the worm gear assembly 276, power transmission in the backward direction may be limited. Therefore, when the operation of the front transfer motor 275 is stopped, a state in which the front wheel 220 is moved to the outside of the main body 210 or a state in which the front wheel 220 is moved to the inside of the main body 210 may be maintained.
[0085] Referring to
[0086] The rear wheel support member 281 is provided in a fork shape to support a shaft of the rear wheel 230. The rear support shaft 282 extends from opposite sides of an upper portion of the rear wheel support member 281 in a width direction of the main body 210 to be rotatably supported on the main body 210. Accordingly, the rear wheel support member 281 may rotate about the rear support shaft 282 for the turning movement of the rear wheel 223.
[0087] The rear transfer driving device 284 may rotate the rear support shaft 282 in the forward or backward direction to move the rear wheel 230 to the outside of the main body 210 or the inside of the main body 210. As illustrated in
[0088] Like the front transfer driving device 274, because the rear transfer driving device 284 employs the worm gear assembly 286, power transmission in the backward direction may be limited. Therefore, when the operation of the rear transfer motor 285 is stopped, a state in which the rear wheel 230 is moved to the outside of the main body 210 or a state in which the front wheel 220 is moved to the inside of the main body 210 may be maintained.
[0089] As illustrated in
[0090] The personal mobility 200 of the second embodiment may also be loaded using the loading apparatus 300 as illustrated in
[0091] As illustrated in
[0092] The second embodiment illustrates a method in which the front wheel support device 270 and the rear wheel support device 280 turn the front wheel 220 and the rear wheel 230 respectively to move to the inside and outside of the body 210, but the front wheel support device 270 and the rear wheel support device 280 are not limited thereto. The front wheel support device 270 and the rear wheel support device 280 may be provided in a method in which the front wheel 220 and the rear wheel 230 move to the inside and outside of the body 210 by sliding, respectively.
[0093] As is apparent from the above, a personal mobility according to an embodiment of the disclosure includes a main body having a box shape and is configured such that a steering handle enters the inside of the main body when loaded, so that transportation and loading are easy, loading efficiency can be increased, and safe storage can be secured.
[0094] Further, the personal mobility according to an embodiment of the disclosure is configured such that not only a steering shaft and the steering handle, but also front and rear wheels completely enter the inside of the main body, loading efficiency can be increased, safe loading can be secured, and the steering handle, the front wheel, the rear wheel, and the like can be safely protected after being loaded.
[0095] Further, a loading apparatus for the personal mobility according to an embodiment of the disclosure includes a loading rack having loading spaces corresponding to a width of the main body of the personal mobility, and coupling bars mounted to penetrate the loaded personal mobility and the loading rack in a lateral direction, a plurality of the personal mobilities transformed into a box shape when loaded can be stably loaded, and the plurality of loaded personal mobilities can be easily coupled within the loading rack.
