The electric moving body 1 according to the present embodiment includes a loading unit 5 that is supported by a frame 11 and can load a heavy object, and is arranged above the loading platform 6 by a first distance or more. Therefore, the electric moving body 1 does not require the user to bend down when loading / unloading a person on the loading section 5, loading a load on the loading section 5, or unloading the load from the loading section 5. The labor of the user can be reduced. Although it is a familiar explanation, the electric mobile body 1 can, for example, load shopping on the loading unit 5 and unload shopping from the loading unit 5 without bending down when the user is shopping.

Further, the electric moving body 1 according to the present embodiment can be boarded on the loading platform 6 in the deployed state. Therefore, the electric moving body 1 can reduce the labor for the user to manually push the electric moving body 1 as needed. The electric mobile body 1 can be used, for example, as a means of transportation when the user is tired of walking during shopping.

Further, the overall length of the electric moving body 1 according to the present embodiment can be shortened by accommodating the loading platform 6. Therefore, the electric moving body 1 can be parked in a narrower parking space.

Furthermore, the electric moving body 1 according to the present embodiment includes a handle portion 22 provided on the loading platform 6 and a loading platform fixing portion 25 connected to the handle portion 22 to support the loading platform 6. Therefore, the electric moving body 1 can support the loading unit 5 with the loading platform 6 in the stored state of the loading platform 6. That is, the electric moving body 1 can increase the load weight of the load unit 5 by strengthening the support of the load unit 5 in the stored state of the load platform 6.

Further, the electric moving body 1 according to the present embodiment includes a second caster 29 which is provided on the loading platform 6 and supports the loading platform 6 so as to be able to travel in the stored state. Therefore, the electric moving body 1 can travel even when the loading platform 6 is folded (that is, in a stored state). That is, the electric moving body 1 is supported by the first wheel 12 and the first caster 21 in the deployed state of the loading platform 6, and is supported by the first wheel 12 and the second caster 29 in the retracted state of the loading platform 6. Therefore, the electric moving body 1 shares the load of the first caster 21 and the second caster 29 for each state of the loading platform 6 (for each form of the electric moving body 1), and the first caster 21 and the second caster 29, respectively. The load can be reduced.

Further, the electric moving body 1 according to the present embodiment includes a switching mechanism 26 capable of switching the loading unit 5 into a swingable state or a fixed state, and a braking mechanism 27 for damping the shaking of the loading unit 5 in the swingable state. , Is equipped. Therefore, the electric moving body 1 cushions the loading portion 5 from, for example, an impact when overcoming a step. Further, when the loading portion 5 is set to the seat 63, the electric moving body 1 can switch the seat 63 to a swingable state to improve the riding comfort.

Furthermore, the electric moving body 1A according to the present embodiment includes a strut portion 141 that can be attached to and detached from the loading platform 6 and can be expanded and contracted, and a second seat 142 provided at the protruding end portion of the strut portion 141. There is. Therefore, the electric moving body 1A can further reduce the burden on the user by not only standing on the loading platform 6 but also sitting on the second seat 142 of the loading platform 6.

Further, the electric mobile bodies 1 and 1A according to the present embodiment include a pair of left and right main frames 31 that support the loading unit 5. Therefore, the electric mobile bodies 1 and 1A can secure a space below the loading section 5 and between the left and right main frames 31 so that the load can be loaded in addition to the loading section 5 and the loading platform 6. This space can be loaded with luggage from both the front and the back.

Therefore, the electric mobile bodies 1 and 1A according to the present embodiment reduce the labor of the user and improve the usability.
