[0046] Figure 2is a view exemplarily showing a vehicle component fixing device according to an exemplary embodiment of the present disclosure, Figure 3 is a view exemplarily showing a cross-section taken along Figure 2 line A-A' in, and Figure 4 is a view exemplarily showing an exemplary embodiment of a disassembly / attachment module of the vehicle component fixing device.

[0047] Referring to Figure 2 and Figure 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 disposed in the vehicle body and to which the detachable unit is coupled. A circular magnet 317 is rotatably disposed inside the assembly module 300, and when the circular magnet 317 rotates, the detachable unit 100 is mechanically fastened to the vehicle body, and a magnetic circuit is simultaneously changed as the circular magnet 317 rotates, so that the detachable unit 100 is magnetically fastened to the vehicle body.

[0048] The detachable unit 100 can be assembled to the vehicle body to provide an additional internal space. For example, the detachable unit 100 can be provided with a seat for a passenger to sit on, or can be provided with a space for loading luggage. The detachable unit 100 can include a bottom floor 103 forming a bottom portion of the internal space, and the bottom floor 103 can be provided with components for assembling the detachable unit 100 to the vehicle body.

[0049] The detachable unit 100 can be assembled to the vehicle body via the assembly module 300, which will be described below.

[0050] The assembly module 300 can be disposed in the vehicle body. The assembly module 300 can be disposed on a vehicle body bottom floor 301 forming the vehicle body. The rotatable circular magnet 317 is disposed inside the assembly module 300. When the circular magnet 317 rotates, the detachable unit 100 can be mechanically fastened to the vehicle body, and in response to the rotation of the circular magnet 317, a magnetic circuit (i.e., a magnetic flux path) is simultaneously changed therewith, so that the detachable unit 100 can be magnetically fastened to the vehicle body.

[0051] Meanwhile, a detachable module 500 can be provided, which is configured to rotate the circular magnet 317. The detachable module 500 can be disposed outside or inside the vehicle. The detachable module 500 can rotate the circular magnet 317 inside the assembly module 300 by receiving power from outside the vehicle or from the vehicle.

[0052] Referring to Figure 4, in an exemplary embodiment of the present disclosure, the detachable module 500 may include a coil 510. In addition, the detachable module is separately provided outside the vehicle. When current is supplied to the coil 510, the coil 510 acts as an electromagnet, and the circular magnet 317 located near the coil 510 rotates by electromagnetic force.

[0053] Reference Figure 6 , in another exemplary embodiment of the present disclosure, the detachable module may be a device configured to supply power to the drive motor 320. When power is supplied to the drive motor 320, the drive motor 320 is driven, and the circular magnet 317 rotates.

[0054] A detailed description of each exemplary embodiment will be provided later.

[0055] Hereinafter, the mechanical fastening and magnetic fastening of the detachable unit 100 by the rotation of the circular magnet 317 will be described. The differences between the various exemplary embodiments to be described later and the embodiments described above are only that the methods of rotating the circular magnet 317 are different, but the similarities with the embodiments described above are that both the mechanical fastening and the magnetic fastening are performed simultaneously by the rotation of the circular magnet 317.

[0056] Reference Figure 2 , Figure 3 and Figure 7 , a swinging member 323 is provided inside the assembly module 300, and the swinging member is configured to rotate as the circular magnet 317 rotates. The swinging member 323 is inserted into the detachable unit 100 to mechanically fasten the detachable unit 100 to the vehicle body. The circular magnet 317 and the swinging member 323 may be rotationally associated such that when the circular magnet 317 rotates, the swinging member 323 may also rotate in the same direction as the circular magnet.

[0057] To rotationally associate the circular magnet 317 and the swinging member 323, the circular magnet 317 is provided with a first shaft 332 extending outside the assembly module 300, the swinging member 323 is provided with a second shaft 334 extending outside the assembly module, and the first shaft 332 and the second shaft 334 may be linked to each other via a belt member 340.

[0058] In other words, when the circular magnet 317 rotates through the detachable module 500, the first shaft 332 may rotate in response to the rotation of the circular magnet 317, and when the second shaft 334 connected to the first shaft 332 rotates, the swinging member 323 may also rotate.

[0059] In this case, the first pulley 331 is connected to the first shaft 332, the second pulley 333 is connected to the second shaft 334, and the belt member 340 is connected to the outer peripheries of the first pulley 331 and the second pulley 333, such that the first shaft 332 and the second shaft 334 can be rotationally associated.

[0060] In addition, a coupling groove 121 that is recessed upward can 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 can be recessed upward into the coupling flange 120.

[0061] Accordingly, the detachable unit 100 can be moved so that the swing member 323 can slide into the coupling groove 121. When the detachable unit 100 and the assembly module 300 are matched, the circular magnet 317 can rotate, and in response to the rotation of the circular magnet 317, the swing member 323 can rotate within the coupling groove 121, such that the detachable unit 100 can be mechanically fastened to the vehicle body.

[0062] Meanwhile, the swing member 323 has a semi-circular shape with one side protruding, and the coupling groove 121 has a shape that is recessed along the path along which the swing member 323 slides, and the upper end portion of the coupling groove 121 is formed in a semi-circular shape, such that after the swing member 323 is received in the upper end portion of the coupling groove, it can rotate and be connected to the detachable unit 100, thereby enabling the detachable unit to be fastened to the vehicle body.

[0063] Reference Figure 2 、 Figure 3 and Figure 7 and, a rod-shaped magnet 315 is provided inside the assembly module 300, and the rod-shaped magnet is fixed at a position spaced apart from the circular magnet 317. The rod-shaped magnet 315 can be provided at a position spaced apart from the circular magnet 317 by a predetermined distance upward or downward, and is arranged such that the polarity of the rod-shaped magnet 315 is fixed in a predetermined direction inside the assembly module 300. Accordingly, when the polarity orientation of the circular magnet 317 changes in response to the rotation of the circular magnet 317, the magnetic circuit (i.e., the magnetic flux path) provided by the rod-shaped magnet 315 and the circular magnet 317 changes, such that the detachable unit 100 can be magnetically fastened to the vehicle body or separated from the vehicle body.

[0064] The assembly module 300 can include a pair of pole plates 311 that form the side walls of the assembly module 300 and serve as a magnetic flux movement path for the circular magnet 317, and the circular magnet 317 can be received inside the pair of pole plates 311.

[0065] In addition, the rod-shaped magnet 315 can be set to be fixed inside a pair of electrode plates 311 and above the circular magnet 317, and the swing member 323 (which rotates as the circular magnet 317 rotates) can be set above the rod-shaped magnet 315.

[0066] Refer to Figure 7 , before the detachable unit 100 is connected to the assembly module 300, the circular magnet 317 and the rod-shaped magnet 315 are arranged with different polar orientations. Due to the property that magnetic flux exits from the N pole and moves to the S pole, the magnetic flux path is shown as in the attached drawings.

[0067] However, when the circular magnet 317 rotates and is arranged with the same polar orientation as the rod-shaped magnet 315, the magnetic flux exits from the N pole and moves to the S pole due to the same property. However, at this time, since the magnetic flux inevitably flows into the metal detachable unit and passes through the detachable unit 100 made of a metal material, a magnetic force acts on the detachable unit 100, causing the detachable unit 100 to be magnetically fastened to the assembly module 300.

[0068] In addition, the swing member 323 rotates in response to the rotation of the circular magnet 317, so that the detachable unit 100 and the assembly module 300 are firmly fixed by locking the swing member 323 into the coupling groove 121.

[0069] Generally, refer to Figure 7 , when the circular magnet 317 and the rod-shaped magnet 315 are arranged with the same polar orientation, it can be seen that the detachable unit 100 is fastened to the vehicle body by magnetic force. In addition, refer to Figure 8 , when the circular magnet 317 and the rod-shaped magnet 315 are arranged with different polar orientations, it can be seen that the detachable unit 100 is separated from the vehicle body.

[0070] In other words, as shown in Figure 8 , when the circular magnet 317 rotates and is arranged with a polar orientation different from that of the rod-shaped magnet 315, the magnetic flux path changes and the magnetic force no longer acts on the detachable unit 100. In addition, the swing member 323 rotates in response to the rotation of the circular magnet 317, and the mechanical fastening is also released, enabling the detachable unit 100 to be easily separated from the assembly module 300.

[0071] An exemplary embodiment in which the detachable module 500 includes a coil 510 will be described. Refer to Figure 5 , the detachable module 500 moves below the assembly module 300 and is positioned close to the circular magnet 317. When an electric current is applied to the coil 510, the coil 510 applies an electromagnetic force to the circular magnet 317, enabling the circular magnet 317 to rotate.

[0072] When the circular magnet 317 rotates, the detachable unit 100 can be mechanically and magnetically coupled via the swing member 323 as described above.

[0073] When the circular magnet 317 rotates again, the swing member 323 rotates and the mechanical fastening is released, and at the same time the magnetic circuit changes accordingly, so that the magnetic flux does not move to the detachable unit 100. Therefore, the magnetic fastening is released and the detachable unit 100 can be easily separated from the assembly module 300.

[0074] In an exemplary embodiment of the present disclosure, in order to rotate the circular magnet 317 again, the direction of the current applied to the coil 510 is reversed, so that the coil 510 applies an electromagnetic force to the circular magnet 317 in the opposite direction, thereby enabling the circular magnet 317 to rotate in the opposite direction.

[0075] 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. Refer to Figure 6 , a drive motor 320 for rotating the circular magnet 317 may be provided on the outer side of the assembly module 300, and the drive motor 320 may receive power via the detachable module to rotate the circular magnet 317 inside the assembly module 300.

[0076] Although not shown, the detachable module is configured as a power supply source capable of rotating the drive motor 320.

[0077] In Figure 2 The reference numerals 331 and 333, which are represented as the first pulley and the second pulley, are respectively represented as the first gear and the second gear in Figure 6

[0078] 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 engages with the first gear 331 on one side and with 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 magnet 317 can rotate.

[0079] The drive motor 320 is provided with a fourth shaft 338, and a fourth gear 337 is connected to the fourth shaft 338 such that the fourth gear 337 can engage with the third gear 335.

[0080] 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 magnet 317 can Figure 2is connected to the rotating shaft of the drive motor 320 in the form shown. The circular magnet 317 can be rotated by connecting the first shaft 332 included in the circular magnet 317 to the rotating shaft of the drive motor.

[0081] Meanwhile, in the above example, the assembly module 300 is disposed in the vehicle body, and the detachable unit 100 is assembled to the assembly module. Conversely, an exemplary embodiment in which the assembly module is disposed in the detachable unit is also possible.

[0082] In other words, the design of the above detachable unit can be changed to be disposed on the vehicle, and the coupling groove can be recessed downward into the top surface of the vehicle body.

[0083] A swing member that engages with the circular magnet and is configured to rotate as the circular magnet rotates is disposed inside the assembly module, where the assembly module is disposed in the detachable unit. When the detachable unit is fastened to the vehicle body, as the swing member slides in the coupling groove and is received at the lower end portion of the coupling groove, the swing member rotates as the circular magnet rotates, so that the detachable unit can be mechanically and magnetically fastened to the vehicle body.

[0084] In addition, terms such as "unit" and "module" included in this specification refer to a unit for processing at least one function or operation, which can be implemented by hardware, software, or a combination thereof.

[0085] In an exemplary embodiment of the present disclosure, a vehicle can be referred to based on a concept including various transportation modes. In some cases, a vehicle can be interpreted based on a concept including not only various land transportation modes (such as cars, motorcycles, trucks, and buses traveling on roads), but also other transportation modes such as airplanes, drones, and ships.

It should also be understood that the term "connected" or its derivatives refers to both direct connection and indirect connection.

[0087] The term "and / or" can include combinations of multiple related listed items or any one of the multiple related listed items. For example, "A and / or B" includes all three cases, such as "A", "B", and "A and B".

[0088] In an exemplary embodiment of the present disclosure, "at least one of A and B" may refer to "at least one of A or B" or "at least one combination in a combination of at least one of A and B". Further, "one or more of A and B" may refer to "one or more of A or B" or "one or more combinations in a combination of one or more of A and B".

[0089] In this specification, unless otherwise specified, singular expressions include plural expressions, unless the context clearly indicates otherwise.

[0090] In an exemplary embodiment of the present disclosure, it should be understood that terms such as "comprising" or "having" are intended to specify the presence of features, quantities, steps, operations, elements, parts, or combinations thereof described in the specification, and do not exclude the possibility of adding or the presence of one or more other features, quantities, steps, operations, elements, parts, or combinations thereof.
