Patent number: 11325490Abstract: The present invention relates to a movable station. More particularly, the present invention relates to a movable station including a vehicle, a multi-tier open frame rack installed in the vehicle, and multiple accommodation modules mounted on each tier of the rack and each of which stably secures an electric kick scooter. With the use of the movable station, many electric kick scooters can be picked up easily and stably carried. In addition, damage to the electric kick scooters and stable placement frames can be prevented during transportation of the electric kick scooters.Type: GrantFiled: July 25, 2019Date of Patent: May 10, 2022Assignee: EV PASS CO., LTDInventors: Seung Bo Hyun, Hae Yong Yang, Yeon Tae Kim, Hyung Moon Lee, Hye Jin Song

Publication number: 20210334893Abstract: The present invention relates to a tourism-associated electric kick scooter rental system and, more particularly, to a tourism-associated electric kick scooter rental system in which a tourism product and a product for leasing an electric kick scooter are associated. With the use of the system, many advantages can be obtained. That is, an associated business operator can easily sell the tourism product. Since the associated business operator has to lease the electric kick scooter in order to sell the tourism product, an administrator can easily get a business operator that will use the system. In addition, various products in which the tourism product and the leasing of the electric kick scooter are associated can be offered. In addition, the associated business operator and the administrator can easily secure customers and thus the cost of a product can be lowered. Further, a user can use the product at a low price.Type: ApplicationFiled: August 7, 2019Publication date: October 28, 2021Inventors: Seung Bo Hyun, Hae Yong Yang, Yeon Tae Kim, Hyung Moon Lee, Hye Jin Song
