Referring to FIG. 1, an additional internal space is ensured by coupling a cabin 10 and a loading unit 20 of a vehicle to each other. In the instant case, it is very important in terms of passenger safety to firmly attach the cabin 10 and the loading unit 20 of the vehicle to each other.

Conventionally, to couple the cabin 10 and the loading unit 20 of the vehicle to each other, one of a mechanical fixation and magnetic fixation is generally used. However, in the case of mechanical fixation, additional labor is required to assemble or disassemble the cabin 10 and the loading unit 20, and there is a problem in that durability is reduced due to frequent assembly and disassembly.

Furthermore, in the case of the magnetic fixation, there is a problem in that the fixing force between the cabin 10 and the loading unit 20 is insufficient compared to the mechanical fixation.

Accordingly, there is a need for a method to increase the coupling force by mechanically and magnetically fixing the cabin 10 and the loading unit 20 of the vehicle.

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.

Referring to FIG. 2 and FIG. 3, a vehicle component fixing device according to an exemplary embodiment of the present disclosure includes: a detachable unit 100 assembled to a vehicle body to form an internal space; and an assembly module 300 which is provided in the vehicle body and to which the detachable unit is coupled. A circular magnetic body 317 is rotatably provided inside the assembly module 300, and when the circular magnetic body 317 is rotated, the detachable unit 100 is mechanically fastened to the vehicle body, and a magnetic circuit is changed simultaneously therewith so that the detachable unit 100 is magnetically fastened to the vehicle body.

The detachable unit 100 may be assembled to the vehicle body to provide an additional internal space. For example, the detachable unit 100 may be provided with a seat for passengers to board, or may be provided with a space for loading luggage. The detachable unit 100 may include a bottom floor 103 that forms the bottom portion of the internal space, and the bottom floor 103 may be provided with components for assembling the detachable unit 100 to the vehicle body.

The detachable unit 100 may be assembled to the vehicle body via the assembly module 300, which will be described below.

The assembly module 300 may be provided in the vehicle body. The assembly module 300 may be provided on the vehicle body bottom floor 301 that forms the vehicle body. The rotatable circular magnetic body 317 is provided inside the assembly module 300. When the circular magnetic body 317 rotates, the detachable unit 100 may be mechanically fastened to the vehicle body, and a magnetic circuit, i.e., the path of magnetic fluxes, is changed simultaneously therewith in response to the rotation of the circular magnetic body 317 so that the detachable unit 100 may be magnetically fastened to the vehicle body.

Furthermore, the detachable module is separately provided outside the vehicle. When current is supplied to the coil 510, the coil 510 functions as an electromagnet, and the circular magnetic body 317 located adjacent to the coil 510 is rotated by an electromagnetic force.

Referring to FIG. 6, in another exemplary embodiment of the present disclosure, the detachable module may be a device configured to supply power to a drive motor 320. When the power is supplied to the drive motor 320, the drive motor 320 is driven, and the circular magnetic body 317 is rotated.

A detailed description of various exemplary embodiments will be provided later.

Hereinafter, the mechanical fastening and magnetic fastening of the detachable unit 100 by the rotation of the circular magnetic body 317 will be described. Various exemplary embodiments to be described later differs from the above-described embodiment only in the method of rotating the circular magnetic body 317, but is the same as the above-described embodiment in that the mechanical fastening and magnetic fastening are simultaneously executed by the rotation of the circular magnetic body 317.

Referring to FIG. 2 and FIG. 3 and FIG. 7, a rocker 323 configured to rotate in conjunction with the rotation of the circular magnetic body 317 is provided inside the assembly module 300. The rocker 323 is inserted into the detachable unit 100 to mechanically fasten the detachable unit 100 to the vehicle body. The circular magnetic body 317 and the rocker 323 may be linked in rotation so that when the circular magnetic body 317 is rotated, the rocker 323 can also be rotated in the same direction thereof.

To link the circular magnetic body 317 and the rocker 323 in rotation, the circular magnetic body 317 is provided with a first shaft 332 that protrudes to the outside of the assembly module 300, the rocker 323 is provided with a second shaft 334 that protrudes to the outside of the assembly module, and the first shaft 332 and the second shaft 334 may be linked with each other via a belt 340.

That is, when the circular magnetic body 317 is rotated by the detachable module 500, the first shaft 332 may be rotated in response to the rotation of the circular magnetic body 317, and as the second shaft 334 connected to the first shaft 332 is rotated, the rocker 323 may be rotated as well.

In the instant case, a first pulley 331 is coupled to the first shaft 332, a second pulley 333 is coupled to the second shaft 334, and a belt 340 is coupled to the external perimeters of the first pulley 331 and the second pulley 333 so that the first shaft 332 and the second shaft 334 may be linked in rotation.

Furthermore, a coupling groove 121 recessed upward may be provided on the bottom surface of the detachable unit 100. A coupling flange 120 is provided on the bottom surface of the bottom floor 103 of the detachable unit 100, and the coupling groove 121 may be recessed upward into the coupling flange 120.

Accordingly, the detachable unit 100 may be moved so that the rocker 323 may be slid into the coupling groove 121. When the detachable unit 100 and the assembly module 300 are matched, the circular magnetic body 317 may be rotated, and in response to the rotation of the circular magnetic body 317, the rocker 323 may be rotated within the coupling groove 121 so that the detachable unit 100 may be mechanically fastened to the vehicle body.

Meanwhile, the rocker 323 includes a semicircular shape with one side protruding, and the coupling groove 121 includes a shape recessed along the path along which the rocker 323 is slid, and the upper end portion of the coupling groove 121 is formed in a semicircular shape so that, after being accommodated therein, the rocker 323 may be rotated and coupled to the detachable unit 100, enabling the detachable unit to be fastened to the vehicle body.

Referring to FIG. 2 and FIG. 3 and FIG. 7, a rod magnetic body 315 is provided inside the assembly module 300 to be fixed at a position spaced from the circular magnetic body 317. The rod magnetic body 315 may be provided at a position spaced upward or downward from the circular magnetic body with a predetermined distance 317 and is provided so that polarities of rod magnetic body 315 are fixed in a predetermined direction inside the assembly module 300. Therefore, when the polar orientation of the circular magnetic body 317 is changed in response to the rotation of the circular magnetic body 317, the magnetic circuit provided by the rod magnetic body 315 and the circular magnetic body 317, that is, the path for magnetic fluxes, is changed, so that the detachment unit 100 may be magnetically fastened to or disassembled from the vehicle body.

The assembly module 300 may include a pair of pole panels 311 that form side walls of the assembly module 300 and serve as a movement path for the magnetic fluxes of the circular magnetic body 317, and the circular magnetic body 317 may be accommodated inside the pair of pole panels 311.

Furthermore, the rod magnetic body 315 may be provided to be fixed inside the pair of pole panels 311 and on the upper side of the circular magnetic body 317, and the rocker 323, which rotates in conjunction with the rotation of the circular magnetic body 317, may be provided on the upper side of the rod magnetic body 315.

Referring to FIG. 7, before the detachable unit 100 is coupled to the assembly module 300, the circular magnetic body 317 and the rod magnetic body 315 are disposed with different polar orientations. The path of magnetic fluxes appears as illustrated in the drawing due to the nature of magnetic fluxes coming out from the N pole and moving to the S pole.

However, when the circular magnetic body 317 is rotated and disposed with the same polar orientation as the rod magnetic body 315, the magnetic fluxes come out from the N pole and move to the S pole due to the same property. However, at the instant time, since the magnetic fluxes inevitably flow to the metal detachable unit and move through the detachable unit 100 made of a metal material, a magnetic force acts on the detachable unit 100 so that the detachable unit 100 is magnetically fastened to the assembly module 300.

Furthermore, the rocker 323 is rotated in response to the rotation of the circular magnetic body 317 so that the detachable unit 100 and the assembly module 300 are firmly secured by the rocket 323 locked to the coupling groove 121.

In summary, referring to FIG. 7, when the circular magnetic body 317 and the rod magnetic body 315 are disposed with the same polar orientation, it may be seen that the detachable unit 100 is fastened to the vehicle body by a magnetic force. Furthermore, referring to FIG. 8, when the circular magnetic body 317 and the rod magnetic body 315 are disposed with different polar orientations, it may be seen that the detachable portion 100 is disassembled from the vehicle body.

That is, as illustrated in FIG. 8, when the circular magnetic body 317 is rotated and disposed with a polar orientation different from that of the rod magnetic body 315, the path for magnetic fluxes is changed and the magnetic force no longer acts on the detachable unit 100. Furthermore, the rocker 323 is rotated in response to the rotation of the circular magnetic body 317 and the mechanical fastening is also released so that the detachable unit 100 may be easily disassembled from the assembly module 300.

An exemplary embodiment in which the detachable module 500 includes a coil 510 will be described. Referring to FIG. 5, the detachable module 500 moves to the underneath of the assembly module 300 and is located close to the circular magnetic body 317, and when current is applied to the coil 510, the coil 510 applies an electromagnetic force to the circular magnetic body 317 so that the circular magnetic body 317 may be rotated.

When the circular magnetic body 317 is rotated, the detachable unit 100 may be mechanically and magnetically coupled via the rocker 323 as described above.

When the circular magnetic body 317 is rotated again, the rocker 323 is rotated and the mechanical fastening is released, and the magnetic circuit is changed simultaneously therewith so that the magnetic fluxes do not move to the detachment unit 100. Therefore, the magnetic fastening is released and the detachable unit 100 may be easily disassembled from the assembly module 300.

In an exemplary embodiment of the present disclosure, so as to rotate the circular magnetic body 317 again, the direction to which current is applied to the coil 510 is reversed, such that the coil 510 applies an electromagnetic force to the circular magnetic body 317 in the opposite direction so that the circular magnetic body 317 may be rotated in the opposite direction.

In another exemplary embodiment of the present disclosure, an exemplary embodiment in which the detachable module is a device configured to supply power to the drive motor 320 will be described. Referring to FIG. 6, a drive motor 320 may be provided on the external side of the assembly module 300 to rotate the circular magnetic body 317, and the drive motor 320 may receive power via the detachable module to rotate the circular magnetic body 317 inside the assembly module 300.

Although not illustrated, the detachable module is configured as a power supply source that can rotate the drive motor 320.

The reference numerals 331 and 333 denoted as first pulley and second pulley in the FIG. 2 will be denoted as first gear and second gear respectively in FIG. 6,

Meanwhile, a third shaft 336 is provided outside the assembly module 300, and a third gear 335 may be coupled to the third shaft 336. The third gear 335 is engaged to the first gear 331 on one side and to the drive motor 320 on the other side to transmit the driving force of the drive motor 320 to the first gear 331 through the third gear 335 so that the circular magnetic body 317 may be rotated.

The drive motor 320 is provided with a fourth shaft 338, and a fourth gear 337 is connected to the fourth shaft 338 so that the fourth gear 337 may be engaged to the third gear 335.

The drive motor 320 may also be provided inside the assembly module 300. When the drive motor 320 is provided inside the assembly module 300, the circular magnetic body 317 may be connected to a rotation shaft of the drive motor 320 in the form illustrated in FIG. 2. The circular magnetic body 317 may be rotated by connecting the first shaft 332 included in the circular magnetic body 317 to the rotation shaft of the drive motor.

Meanwhile, in the above-described example, the assembly module 300 is provided in the vehicle body, and the detachable unit 100 is assembled to the assembly module, but on the other hand, an exemplary embodiment in which the assembly module is provided in the detachable unit is also possible.

That is, the design of the above-mentioned detachable unit may be changed to be provided on the vehicle, and the coupling groove may be recessed downward in a top surface of the vehicle body.

The rocker engaged to the circular magnetic body and configured to be rotated in conjunction with the rotation of the circular magnetic body is provided inside the assembly module provided in the detachable unit. When the detachable unit is fastened to the vehicle body, the rocker is rotated in conjunction with the rotation of the circular magnetic body while the rocker slides in the coupling groove and accommodated at the upper end portion of the coupling groove, so that the detachable unit may be mechanically and magnetically fastened to the vehicle body.
