Description of the state of the art

[0002] In a vehicle, a seat can be adjusted forwards and backwards so that a passenger can adapt the seat to their physical needs or create space in front of and behind the seat. In a conventional method, the passenger manually operates a lever, causing the seat to slide or move forwards and backwards along a track on the vehicle floor, where it locks into place. Recently, various electric seats have also been developed that can be moved or slid back and forth at the touch of a button.

[0003] The electric seats essentially require a drive system and a locking mechanism. The existing drive system and locking device have a complex structure and therefore take up a considerable amount of space, and the wiring for the power supply also needs to be taken into account.

[0004] Therefore, there is a need for an electric rail that not only takes up minimal space with a simple structure and can be easily powered, but can also be easily used for different sections of the vehicle, such as a different console of the seat.

[0005] From KR 10 2 117 034 B1, a sliding unit for a vehicle is already known, comprising: a rail provided on the vehicle; a fastening section formed from a material through which magnetism can flow and provided along a direction in which the rail extends; a movable section that is slidable along the rail; and a magnetic module provided in the movable section, arranged in the direction of the fastening section and optionally locked to the fastening section by a magnetic path in order to optionally fasten the movable section to the rail.

[0006] DE 10 2019 135 374 A1 further discloses a rail for a vehicle seat with first and second sliding rail sections, driven by a motor-driven drive mechanism. The rail also includes a mechanical lock which, in the event of an accident, is actuated by a relative movement between the motor-driven drive mechanism and the second rail section.

[0007] Furthermore, JP 2018-134972A discloses a sliding unit for a vehicle, the sliding unit comprising: a vehicle floor provided on the vehicle; a mounting section formed of a material through which magnetism can flow; a movable section that is slidable along the vehicle floor; and a magnetic module provided in the movable section, arranged in the direction of the mounting section and optionally locked to the mounting section by a magnetic path in order to optionally fasten the movable section to the rail, wherein the magnetic module comprises: a first fixed permanent magnet that is in contact with the mounting section and is provided in the magnetic module in the direction of the mounting section;and a second permanent magnet provided on an opposite side of the mounting section in the magnet module, wherein the magnet module is locked to or unlocked from the mounting section according to a change in the polarity of the second permanent magnet.

[0008] The information contained in this background section of the present description is provided solely for a better understanding of the general background of the present invention and should not be construed as an acknowledgment or any form of suggestion that this information represents the prior art already known to a person skilled in the art.

[0028] In the figures, the reference numerals in the various figures of the drawing refer to the same or equivalent sections of the present invention. Detailed description

[0029] Reference will now be made in detail to various embodiments of the present invention(s), examples of which are illustrated in the accompanying drawings and described below. While the present invention(s) are described in connection with exemplary embodiments of the present invention, it should be assumed that the present description is not intended to limit the present invention(s) to these exemplary embodiments. On the other hand, the present invention(s) is / are intended to cover not only the exemplary embodiments of the present invention, but also various alternatives, modifications, equivalents, and further embodiments that may be included within the scope and spirit of the present invention, as defined by the appended claims.

[0030] Fig. Figure 1 is a view showing by way of example a state in which a rail and a movable section of a sliding unit for a vehicle are coupled according to various exemplary embodiments of the present invention. Fig. Figure 2 is a view that shows by way of example a state in which the movable section of the sliding unit for a vehicle according to various exemplary embodiments of the present invention is pushed to the rearmost side or to the frontmost side. Fig. Figure 3 is a view showing, by way of example, a magnetic module and a fastening section when the movable section is attached to the rail by supplying a current to the magnetic module of the sliding unit for a vehicle according to various exemplary embodiments of the present invention. Fig. Figure 4 is a view showing, by way of example, the magnetic module and the fastening section when the movable section is separated from the rail by supplying current to the magnetic module of the sliding unit for a vehicle according to various exemplary embodiments of the present invention. Fig. Figure 5 is a view showing by way of example a state in which a rail cover and a drive section of the sliding unit for a vehicle are coupled according to various exemplary embodiments of the present invention.

[0031] Fig. Figure 1 is a view showing by way of example a state in which a rail and a movable section of a sliding unit for a vehicle are coupled according to various exemplary embodiments of the present invention. Fig. Figure 2 is a view that shows by way of example a state in which the movable section of the sliding unit for a vehicle according to various exemplary embodiments of the present invention is shifted to the rearmost side or to the frontmost side thereof.A sliding unit for a vehicle according to various exemplary embodiments of the present invention comprises: a rail 100 provided on the vehicle; a mounting section 110 formed of a material through which magnetism can flow and provided along a direction in which the rail 100 extends; a movable section 120 sliding along the rail 100; and a magnetic module 130 provided in the movable section 120, arranged in the direction of the mounting section 110, and optionally interlocked with the mounting section 110 by a magnetic path to selectively secure the movable section 120 to the rail 100. The rail 100 can extend in a straight line in a predetermined direction from the vehicle floor, such as the longitudinal or lateral direction of the vehicle.

[0032] The sliding unit for a vehicle according to various exemplary embodiments of the present invention has a simple design and minimizes the space occupied by the rail 100, since a locking mechanism using a magnetic module 130 is employed, which enables efficient use of space in the vehicle. A locking mechanism for an existing rail 100 comprises a method using a leadscrew and a fork mechanism. When the seat is locked in the conventional manner, the height of a rail is excessively high, for example, 47 mm or 57 mm. When the height of the rail is excessively high, the rail occupies a large portion of the limited space on the vehicle floor, making efficient use of the space difficult.Therefore, the sliding unit for a vehicle according to various exemplary embodiments of the present invention uses a new locking mechanism using a magnetic module 130 to realize a rail 100 with a slim structure with a rail height of 30 mm.

[0033] Furthermore, the rail 100 in the sliding unit for a vehicle according to various exemplary embodiments of the present invention comprises a rack 160 extending longitudinally on one side, wherein one side of the movable section 120 is provided with a pinion 170 which engages with the rack 160, so that the movable section 120 can slide along the rail 100 when the pinion 170 rotates.

[0034] In other words, the rack 160 is provided on one side of the rail 100 along the rail 100, with a pinion 170 provided at the leading edge of one side of the movable section 120, so that the movable section 120 moves along the rail 100 while the pinion 170 rotates and engages with the rack 160. Accordingly, by controlling the pinion 170, it is possible to easily control the movement of the movable section 120, and by using such a gear structure, it is possible to prevent the magnetic module 130 from being pushed in the longitudinal direction of the vehicle within the locking mechanism.

[0035] In the sliding unit for a vehicle according to various exemplary embodiments of the present invention, the rail 100 is provided with a cable guide 150, wherein the cable guide 150 has one end section which is designed to be connected to a power supply of the vehicle and to extend along the rail 100, wherein the other end section is bent and is connected to an end section of the movable section 120, making it possible to supply the movable section 120 with power.Furthermore, the rail 100 is provided with the cable guide 150, wherein the cable guide 150 has one end section which is connected to the power supply of the vehicle at an end section of the rack 160 and extends along one side of the rail 100 in a direction opposite to that from which the rack 160 extends, and wherein the other end section is bent and is connected to an end section of the movable section 120, making it possible to supply the movable section 120 with power.

[0036] In the sliding unit for a vehicle according to various exemplary embodiments of the present invention, it is important that current is supplied to the magnetic module 130 and a drive system for movement. The use of the cable guide 150 makes it possible to supply the current uniformly while maintaining a slim rail structure. The cable guide 150 can have one end section connected to the vehicle's power supply and the other end section connected to a bracket projecting from an end section of the movable section 120. This eliminates the need for a cable and ensures a continuous current supply while the movable section 120 moves along the rail 100.If the cable guide 150 is connected to the vehicle's power supply at the end section of the rack 160, which is provided on one side of the rail 100, the cable guide 150 can also extend over a larger area as the movable section 120 moves along the rail 100 and supply power to the movable section 120.

[0037] Furthermore, in the sliding unit for a vehicle according to various exemplary embodiments of the present invention, the movable section 120 can have a pinion 170 which is arranged at the other end section opposite the one end section which is connected to the cable guide 150, wherein the magnetic module 130 is provided at a point between one end section of the movable section 120 and the other end section thereof.Since the movable section 120 has such a structure, the pinion 170, located at the front of the movable section 120, can move along the rack 160, which is provided on the rail 100, over the largest possible range. The magnetic module 130 is located at the rear of the pinion 170 to implement a locking mechanism, and the cable guide 150 is connected to the projecting bracket at the rear of the magnetic module 130 to supply the movable section 120 with current evenly over a large range. In other words, since the pinion 170 is located at the front of the movable section 120, a maximum stroke of the movable section 120 along the rear of the rack 160, corresponding to the length of the movable section 120 and the length of the cable guide 150 connected to the movable section 120, can be ensured.

[0038] In the sliding unit for a vehicle according to various exemplary embodiments of the present invention, the rail 100 can be configured with a base and two side walls to form an interior space, wherein the mounting section 110 can be provided on the base, and wherein the movable section 120 can be arranged in the interior space of the rail 100. Therefore, the movable section 120 can move along the rack 160, which is located on a side wall of the rail 100 in the interior space of the rail 100, and the magnetic module 130 can be locked or unlocked with the mounting section 110 on the base.

[0039] The movable section 120 is provided with a sliding roller 180, which is supported and rotated by the lower surface of the rail 100, so that the positions of the upper section and the lower section of the movable section 120 can be adjusted by the sliding roller 180 when the movable section 120 slides, wherein the movable section 120 is provided with a guide roller 190, which is supported and rotated by the side wall of the rail 100, so that the left and right positions of the movable section 120 can be adjusted by the guide roller 190 when the movable section 120 slides.

[0040] The sliding roller 180 supports a lower end section of the movable section and is in contact with the bottom surface of the rail 100 to rotate as the movable section 120 slides along the rail 100. The sliding roller 180 can be located at the front end of the movable section 120, where the pinion 170 is located; at the rear end, connected to the cable guide 150; or at an intermediate point corresponding to the length of the movable section 120 to effectively support it. When the sliding roller 180 is located at the intermediate point, the magnetic module 130 is positioned between the front and rear sliding rollers 180 to lock or unlock the movable section 120 to the mounting section 110.

[0041] The guide roller 190 can be arranged in pairs on the left and right at the front and rear of the movable section 120, the guide roller 190 being supported and rotated by the side wall of the rail 100 or the rack 160 to prevent left and right eccentricity of the movable section 120.

[0042] Fig. Figure 3 is a view showing by way of example a magnetic module 130 and a fastening section 110 when the movable section 120 is attached to the rail 100 by supplying a current to the magnetic module 130 of the sliding unit for a vehicle according to various exemplary embodiments of the present invention. Fig. Figure 4 is a view showing, by way of example, the magnetic module 130 and the fastening section 110 when the movable section 120 is separated from the rail 100 by supplying a current to the magnetic module 130 of the sliding unit for a vehicle according to various exemplary embodiments of the present invention.In the sliding unit for a vehicle according to various exemplary embodiments of the present invention, the magnetic module 130 can be configured with a fixed permanent magnet 210, which has an annular shape and is in contact with the mounting section 110 and is provided in the magnetic module 130 in the direction of the mounting section 110, and can be configured with an electromagnet 200, which is provided on an opposite side of the mounting section 110 in the magnetic module 130 and can be locked to or unlocked from the mounting section 110 according to a change in the polarity of the electromagnet 200. In other words, the magnetic module 130 forms a magnetic path by supplying a current to the electromagnet 200, and when a magnetic pole of the electromagnet 200 changes, the magnetic path formed in the magnetic module 130 changes.

[0043] If the magnetic module 130 and the mounting section 110 together form the magnetic path, the magnetic module 130 can be locked to the mounting section 110, and if the magnetic path is formed only in the magnetic module 130, the magnetic module 130 can be unlocked from the mounting section 110. As shown in Fig. As shown in Figure 3, when current is supplied to the electromagnet 200 to form the magnetic pole of the electromagnet 200 at a section adjacent to the fixed permanent magnet 210 with the same magnetic pole as the adjacent fixed permanent magnet 210, the magnetic path is formed such that it runs through the magnet module 130 and the mounting section 110 together, with the magnet module 130 being accordingly locked to the mounting section 110. As shown in Fig. As shown in Figure 4, when current is supplied to the electromagnet 200 to form the magnetic pole of the electromagnet 200 at a section next to the fixed permanent magnet 210 with a magnetic pole that differs from the adjacent fixed permanent magnet 210, the magnetic path is formed such that it passes only through the magnet module 130 and not through the mounting section 110, with the magnet module 130 being unlocked from the mounting section 110 accordingly.

[0044] Furthermore, the magnetic module 130 maintains a pre-formed magnetic path even when current is supplied to the electromagnet 200 to form the magnetic path, and the current supply is stopped after the magnetic module 130 is locked to or unlocked from the mounting section 110, thus maintaining a state in which the magnetic module 130 is locked to or unlocked from the mounting section 110. Therefore, when the locking mechanism is implemented in the rail 100 using the magnetic module 130, there is a power consumption minimization effect, since current only needs to be supplied to the magnetic module 130 at the moment of locking or unlocking.

[0045] In the sliding unit for a vehicle according to various exemplary embodiments of the present invention, the magnetic module 130 is provided with a rotating permanent magnet 220, which rotates based on a rotational axis thereof. The rotating permanent magnet 220 is rotatable when the direction of the magnetic path flowing through the magnetic module 130 is changed, in order to amplify the magnetic force of the magnetic path flowing through the magnetic module 130. When the magnetic path is formed in the magnetic module 130, the rotating permanent magnet 220 rotates according to an instantaneous current flow, thereby amplifying the magnetic flux of the magnetic path. Accordingly, since the magnetic force of the magnetic path is amplified, the locking force is improved by approximately twofold compared to a case in which only the fixed permanent magnet 210 in the magnetic module 130 is used.

[0046] In other words, when the magnetic module 130 is locked to or unlocked from the mounting section 110 by the instantaneous current, the rotating permanent magnet 220 rotates about a shaft on the central section of the rotating permanent magnet 220 when the magnetic path changes, so that the magnetic flux of the magnetic path can increase and the magnetic module 130 can be easily locked to or unlocked from the mounting section 110.

[0047] As in Fig. As shown in Figure 3, when the magnetic module 130 supplies current to the electromagnet 200, such that the magnetic pole next to the fixed permanent magnet 210 is configured as the same magnetic south pole as the pole of the fixed permanent magnet 210, then the magnetic path flows clockwise along the base of the magnetic module 130. However, the magnetic path passing through the magnetic module 130 and the mounting section 110 is configured in a double manner. Accordingly, the rotating permanent magnet 220 rotates clockwise along the magnetic path, so that the magnetic south pole points upwards and a magnetic north pole points downwards.As a result, even after current is supplied to the electromagnet 200, the magnetic flux generated by the fixed permanent magnet 210 and the magnetic flux generated by the rotating permanent magnet 220 are added to increase the magnetic flux, maintaining the magnetic path to pass together through the magnet module 130 and the mounting section 110, so that the magnet module 130 can be locked to the mounting section 110.

[0048] Furthermore, as in Fig. As shown in Figure 4, when the magnetic module 130 supplies current to the electromagnet 200, such that the magnetic pole adjacent to the fixed permanent magnet 210 is configured as the magnetic north pole (different from the pole of the fixed permanent magnet 210), the magnetic path flows in a counterclockwise direction based on the magnetic module 130. However, the magnetic path does not pass through the mounting section 110 and flows only within the magnetic module 130. Accordingly, the rotating permanent magnet 220 rotates counterclockwise along the magnetic path, so that the magnetic south pole is oriented downwards and the magnetic north pole is oriented upwards. As a result, even after the current supply to the electromagnet 200 is stopped, the magnetic path is maintained so that it only passes through the magnetic module 130, allowing the magnetic module 130 to be unlocked from the mounting section 110.

[0049] Fig.Figure 5 is a view illustrating an exemplary state in which a rail cover and a drive section of the sliding unit for a vehicle are coupled according to various exemplary embodiments of the present invention. In the sliding unit for a vehicle according to various exemplary embodiments of the present invention, the rail 100 can be provided with a rail cover 300 extending longitudinally along the upper end sections of the side walls, wherein a longitudinally extending slotted hole can be formed in the rail cover 300, wherein a drive section 320 can be provided above the rail cover 300 to provide a drive force for the movable section 120, and wherein the drive section 320 and the movable section 120 can be connected by a connecting section 310 that passes through the slotted hole.The drive section 320, located above the rail cover 300, transmits power to the pinion 170 of the movable section 120, which is located inside the rail 100, causing the movable section 120 to slide along the rack 160 to move. Like the locking mechanism, the drive section is a factor that has a significant impact on the structure of a track. If the drive section is complex and occupies a large space, the track structure becomes complicated and the track height excessively high.Therefore, in the sliding unit for a vehicle according to various exemplary embodiments of the present invention, the movable section 120 and the magnetic module 130, which occupy a minimal space, and the cable guide 150 for the power supply can be arranged in the interior of the rail 100, wherein the movable section 120 can be connected to the drive section 320 by the connecting section 310, which passes through the slotted hole provided in the rail cover 300, thereby realizing a simple and slim rail 100.

[0050] In the sliding unit for a vehicle according to various exemplary embodiments of the present invention, the rail 100 can be provided on the vehicle floor, wherein a seat can be coupled to the movable section 120 to slide along the rail 100 on the vehicle floor. The rail 100 can also be provided on the vehicle floor, wherein the seat can be coupled to the connecting section 310 to be mounted above the rail cover 300, wherein the drive section 320 can be arranged in the seat, and wherein the seat can slide along the rail 100 on the vehicle floor. The sliding unit for a vehicle according to various exemplary embodiments of the present invention has the slim rail structure within the vehicle, so that it can be used in a variety of ways within the vehicle, typically for seat movement.The seat can be coupled to the connecting section 310, which is connected to the movable section 120, to move when the movable section 120 slides along the rail 100, and it can be locked to or unlocked from the fastening section 110 using the magnetic module 130, and the drive section 320 can be arranged inside the seat to transmit the force to the movable section 120 in a state that is not visible from the outside.

[0051] Furthermore, the rail 100 can be provided on the vehicle floor, with a console being coupled to the movable section 120 to slide along the rail 100 on the vehicle floor. Due to the simple and slim design of the sliding unit for a vehicle according to various exemplary embodiments of the present invention, it is possible, as described above, to implement the console or other vehicle-internal equipment as well as the seat in such a way that they can be easily coupled to and moved along the upper end section of the rail 100.

[0052] When autonomous vehicles are eventually commercialized in the future, the concept of the driver's seat will gradually disappear, and the need to utilize a vehicle interior will arise. When using the sliding unit for a vehicle according to various exemplary embodiments of the present invention, it is expected that it will be easy to adjust the required space by simply moving devices such as the seat and console within the vehicle.

[0053] According to the sliding unit for a vehicle according to various exemplary embodiments of the present invention, since the movable section 120 slides along the simple and slim rail 100 and can be locked or unlocked on the rail 100 by implementing the locking mechanism using the magnetic module 130, and can be coupled with various other devices besides the seat, the sliding unit for a vehicle can be used in a variety of ways within the vehicle.
