Description

CROSS REFERENCE TO RELATED APPLICATIONS The present application claims priority to Korean Patent Application No. 10-2024-0156568, filed Nov. 6, 2024, the entire contents of which is incorporated herein for all purposes by this reference. BACKGROUND OF THE PRESENT DISCLOSURE Field of the Present Disclosure The present disclosure relates to a fixing device for personal mobilities, and more particularly, to a fixing device for personal mobilities that allows small mobilities, including wheelchairs, to be secured to large mobilities, including vehicles. Description of Related art In general, wheelchairs and electric wheelchairs are used as a means of transportation for people with impairments or the elderly who have difficulty of moving, and miniaturized electric mobilities are being developed as a convenient means of transportation in addition to the means of transportation for people with difficulty of moving. Recently, as the welfare of the impaired has improved, wheelchairs or electric wheelchairs can board not only wheelchair accessible vehicles but also in general public transportation, thus providing convenience to wheelchair or electric wheelchair users. Against the present backdrop, large transport vehicles that can accommodate wheelchairs or electric wheelchairs are provided with a fixing device to keep a wheelchair or electric wheelchair in a locked state to prevent the wheelchair or electric wheelchair from moving. However, because such fixing devices secure the wheels of a wheelchair or electric wheelchair by holding (restraining) the wheels, the fixation efficiency for the wheelchair or electric wheelchair deteriorates, and when using a belt to secure a wheelchair or electric wheelchair, connecting the belt is inconvenient, and the complicated structure reduces convenience of use. Securing the wheels of a wheelchair or electric wheelchair by holding the wheels may reduce safety due to a decrease in fixation efficiency, which may result in a safety accident. If pressure is applied directly to a wheel, surrounding parts, including the wheel, may be damaged. Moreover, when getting a wheelchair or electric wheelchair off a large transport vehicle, the process of unlocking a fixing device is also complicated. The information included in this Background of the present disclosure is only for enhancement of understanding of the general background of the present disclosure and may not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art. BRIEF SUMMARY Various aspects of the present disclosure are directed to providing a fixing device for personal mobilities that secures small mobilities including wheelchairs to large mobilities including vehicles with strong fixing force, and ensures convenience of use by making it easy to fix or unlock small mobilities. Objectives to be achieved by the present disclosure are not limited to the ones mentioned above, and other objectives not mentioned may be clearly understood by those skilled in the art from the description below. To achieve the objectives of the present disclosure, there is provided a fixing device for personal mobilities, the device including: a connection module provided to an object requiring fixation; and a fixing module provided on a floor surface, into which a portion of the connection module is inserted, and including a first fixing means and a second fixing means for fixing the inserted connection module, wherein the first fixing means may be magnetically fixed to the connection module by generating a magnetic field and the second fixing means may come into contact with the inserted connection module to mechanically fix the connection module. According to an exemplary embodiment of the present disclosure, the fixing module may include: a housing provided on the floor surface; and a fixing holder including a guide groove formed inward of the fixing holder at a top portion of the housing, and the connection module may include a fixing guide whose insertion direction is guided along the guide groove of the fixing holder. According to an exemplary embodiment of the present disclosure, the guide groove of the fixing holder may have an area that gradually narrows inwardly from an entrance portion thereof where insertion of the fixing guide begins. According to an exemplary embodiment of the present disclosure, the fixing holder may be formed so that an upper end portion of an entrance portion thereof where insertion of the fixing guide begins in the guide groove may be inclined downward. According to an exemplary embodiment of the present disclosure, the connection module may include a fixing bracket for connection to the fixing guide, wherein the fixing bracket and the fixing guide may be connected to each other via a connection member while spaced apart, and the connection member may be elastically moved in a direction where the fixing bracket and the fixing gui
