Description

Technical Field

[0001] This disclosure relates to a sliding unit for a vehicle, wherein movable parts coupled to the vehicle’s seats, consoles, etc., can move along a track, the movable parts being locked to or unlocked from the track along a magnetic circuit of a magnetic component disposed in the movable parts, and power is supplied from the track to the magnetic component, the seat, console, or table. Background Technology

[0002] Car seats can be adjusted forward / backward to fit the passenger's body or ensure sufficient fore-and-aft space. Traditionally, users manually operate a lever to slide the seat forward / backward along a track on the vehicle floor, and the seat can then be locked in place. Recently, various types of electric seats have been developed that allow the seat to slide forward / backward by pressing a button.

[0003] Large electric seats require drive systems and locking mechanisms. Traditional drive systems and locking devices have complex structures, occupy a lot of space, and also require complex wiring for power supply.

[0004] Therefore, there is a need for an electric track with a simple structure that occupies minimal space, can be powered in a simple manner, and can be easily applied to various components inside a vehicle (e.g., seats, consoles, etc.).

[0005] The above description of the background art is only for the purpose of helping to understand the background of this disclosure and should not be regarded by those skilled in the art as corresponding to known prior art. Summary of the Invention

[0006] This disclosure has been made to address the aforementioned problems and provides a sliding unit for a vehicle, wherein a locking mechanism is implemented by using a magnetic component, enabling a movable component to slide along a simple and elongated track and to lock or unlock from the track. The movable component can be coupled to various devices other than a seat, and power is supplied from the track to the magnetic component, seat, console, or table. The sliding unit is widely available in vehicle interiors.

[0008] The first contact portion and the second contact portion of the movable component can contact the power supply portion of the first extension portion and the power supply portion of the second extension portion in the curved portion of the track. When the movable component slides along the first extension portion, it can release the contact with the second contact portion, and when the movable component slides along the second extension portion, it can release the contact with the first contact portion.

[0009] Multiple wires, each having a positive electrode and a negative electrode, can be connected to the first contact portion and the second contact portion.

[0010] The movable component may be provided with a first voltage sensor connected to the first contact portion via wiring, a second voltage sensor connected to the second contact portion via wiring, and a switch portion connected to the first voltage sensor and the second voltage sensor via wiring. The first voltage sensor and the second voltage sensor may be configured to measure voltage data of the first contact portion and the second contact portion, and the switch portion may be configured to control the connection between the first contact portion or the second contact portion and the magnetic portion based on the voltage data measured by the first voltage sensor and the second voltage sensor.

[0011] When the movable part slides along the first extension, the switch part can connect the first contact part and the magnetic part according to the voltage data measured by the first voltage sensor. When the movable part sliding along the first extension is located in the curved part of the track, the switch part can connect the second contact part and the magnetic part according to the voltage data measured by the first voltage sensor and the second voltage sensor. When the movable part slides along the second extension, the connection between the first contact part and the magnetic part can be released.

[0012] Multiple wires, each having a positive electrode and a negative electrode, can be connected to the first contact portion and the second contact portion. A wiring groove can extend from the first contact portion and the second contact portion to the center portion of the upper surface of the movable component.

[0018] Multiple bearing sections can be mounted on the outer surface of the movable part. These bearing sections can be supported by the bottom, side, or top surface of the track for rotation. When the movable part slides, the bearing sections can adjust the lateral or vertical position of the movable part.

[0019] A track cover extending along the track and having a slit hole can be provided on the upper surface of the track, and a connecting part that connects to the movable part through the slit hole can be provided on the upper side of the track cover.

[0020] The track can have a rectangular ring shape and can be set on the vehicle floor. Seats, consoles, or tables can be coupled to the connecting part, and the seats, consoles, or tables can slide forward / backward and left / right along the track on the vehicle floor.

[0021] Multiple wires, each with a positive and a negative electrode, can be connected to the first contact portion and the second contact portion. The wires can pass through the slit hole from the top of the movable part to connect to the seat, console, or table.

Figure 2 This is a diagram illustrating a movable component located on a track in a sliding unit for a vehicle according to an embodiment of the present disclosure.

Figure 7 This is a diagram illustrating a voltage sensor and a switch portion disposed in a movable component in a sliding unit for a vehicle according to an embodiment of the present disclosure.

[0033] Figure 1 This is a diagram illustrating the state of a movable component located on a track in a sliding unit for a vehicle according to an embodiment of the present disclosure, moving along the track. The sliding unit for a vehicle according to an embodiment of the present disclosure includes: a track including a first extension 100, a second extension 200, and a curved portion connecting the first extension 100 and the second extension 200; a movable component 300 located on the track to slide along the track, and including a magnetic portion 320 for locking with or unlocking from the track; a first power supply portion 110 and a second power supply portion 210 disposed in the track, having a shape extending along the length direction of the track and electrically connected to a power source (not shown) of the vehicle; and a first contact. Part 410 and second contact part 420 are disposed in the movable member 300 and are electrically connected to the first power part 110 and second power part 210 and the magnetic part 320 by respectively contacting the first power part 110 and the second power part 210. When the movable member 300 slides along the first extension 100, the first contact part 410 and the first power part 110 contact each other, and when the movable member 300 slides along the second extension 200, the second contact part 420 and the second power part 210 of the second extension 200 contact each other. The first contact part 410 and the second contact part 420 may be disposed at points spaced apart from each other, and the track extends on the floor of the vehicle in a predetermined direction, for example, in the longitudinal direction or the transverse direction of the vehicle, and the track is curved to form a closed path.

[0034] Furthermore, in the sliding unit for a vehicle according to an embodiment of the present disclosure, the movable member 300 that slides along the track receives power from the side of the track, and can smoothly receive power from the side of the track behind the curved portion even when the movable member 300 passes through a curved portion of the track and the sliding direction of the movable member changes.

[0035] In the sliding unit for a vehicle according to an embodiment of the present disclosure, the first contact portion 410 and the second contact portion 420 can respectively contact the first power supply portion 110 of the first extension portion 100 and the second power supply portion 210 of the second extension portion 200. When the movable member 300 slides along the first extension portion 100, the contact of the second contact portion 420 can be released, and when the movable member 300 slides along the second extension portion 200, the contact of the first contact portion 410 can be released.

[0036] Specifically, when the movable part 300 moves along the first extension 100, the first contact portion 410 receives power from the first power supply portion 110, and when the movable part slides to be located in the curved portion of the track, the first contact portion 410 contacts the first power supply portion 110 of the first extension 100, and the second contact portion 420 contacts the second power supply portion 210 of the second extension 200. Therefore, when the movable part 300 slides along the first extension 100 or the second extension 200 in the curved portion, the power supply is naturally released in the contact portion in a non-contact state, and power is received from the pre-connected contact portion of the first extension 100 or the second extension 200, thereby allowing the movable part 300 to slide forward / backward or left / right without power interruption.

[0037] Figure 2 This is a diagram illustrating a movable component located on a track in a sliding unit for a vehicle according to an embodiment of the present disclosure. Figure 3 This is a diagram illustrating the contact portion in a sliding unit for a vehicle according to an embodiment of the present disclosure. In the sliding unit for a vehicle according to an embodiment of the present disclosure, multiple wires, each having a positive electrode and a negative electrode, are connected to a first contact portion 410 and a second contact portion 420, and when the first contact portion 410 or the second contact portion 420 is contacted, the first power supply portion 110 and the second power supply portion 210 can supply power to the magnetic portion of the movable component through the wires.

[0038] Furthermore, in the sliding unit for a vehicle according to the embodiments of the present disclosure, multiple wires having positive and negative electrodes are connected to the first contact portion 410 and the second contact portion 420. A wiring groove is formed on the upper surface of the movable member 300 from the first contact portion 410 and the second contact portion 420 to the center portion of the upper surface of the movable member 300, and the multiple wires connected to the first contact portion 410 and the second contact portion 420 can be inserted into the wiring groove for connection.

[0039] In detail, the movable part 300 has a rectangular frame shape, and the track has a rectangular annular shape with four curved portions and four extended portions. A contact portion is provided on each surface of the rectangular frame of the movable part 300, providing a total of four contact portions. When in contact with the side of the track, the contact portion is electrically connected to a first power supply portion 110 and a second power supply portion 210 provided on the side of the track to supply power to a magnetic part connected inside the movable part or to electronic devices (e.g., a seat, console, or table) of the movable part. Therefore, even if the movable part 300 slides after its orientation changes in the curved portions, any side of the movable part 300 is in contact with the side of the track, and the power supply portions 110 and 210, powered from the vehicle's power supply, are provided on the side of the track, thereby continuously supplying power to electronic devices such as seats, consoles, or tables, even when the movable part 300 slides, the electronic devices are connected to the magnetic part inside the movable part 300 or to the movable part itself.

[0040] Each of the multiple wirings has a positive electrode and a negative electrode, and two wirings are connected to each of the contact portions 410 and 420. Therefore, two contact points are provided in each of the contact portions 410 and 420, and each of the first power supply portion 110 and the second power supply portion 210 on the side of the track also has the shape of two track groove extensions, so that the two contact points of the contact portion contact the corresponding power supply portion having the shape of the track groove extension to receive power.

[0041] Furthermore, wiring slots into which wiring can be inserted are provided on the upper surface of the movable member 300, such that a total of eight wirings converging from the four surfaces of the movable member 300 to the central portion of the movable member 300 are inserted into the wiring slots in the movable member 300, which has a rectangular frame shape, and the wirings are connected to two wirings in the central portion of the movable member 300, each including a positive electrode and a negative electrode. Each of the two wirings with positive and negative electrodes protrudes from the central portion of the movable member 300 and extends to the upper end of the movable member 300 to supply power to a seat, console, or table coupled to the upper end of the movable member 300.

[0042] Figure 7 This diagram illustrates a voltage sensor and a switch portion disposed in a movable component of a sliding unit for a vehicle according to an embodiment of the present disclosure. In the sliding unit for a vehicle according to an embodiment of the present disclosure, the movable component 300 may be provided with a first voltage sensor 415 connected to a first contact portion 410 via wiring, a second voltage sensor 425 connected to a second contact portion 420 via wiring, and a switch portion 600 connected to the first voltage sensor 415 and the second voltage sensor 425 via wiring. The first voltage sensor 415 and the second voltage sensor 425 can measure voltage data of the first contact portion 410 and the second contact portion 420, and the switch portion 600 can control the connection between the first contact portion 410 or the second contact portion 420 and the magnetic portion by means of the voltage data measured by the first voltage sensor 415 and the second voltage sensor 425.

[0043] Specifically, in the sliding unit for a vehicle according to an embodiment of the present disclosure, when the movable member 300 slides along the first extension 100, the switch portion 600 can connect the first contact portion 410 and the magnetic portion via voltage data measured by the first voltage sensor 415. When the movable member 300, sliding along the first extension 100, is located in a curved portion of the track, the switch portion 600 can connect the second contact portion 420 and the magnetic portion via voltage data measured by the first voltage sensor 415 and the second voltage sensor 425. The connection between the first contact portion 410 and the magnetic portion can be released when the movable member 300 slides along the second extension 200. The switch portion 600 checks the voltage of the contact portion via a voltage sensor disposed in the contact portion on the side of the movable member 300, and adjusts the switch to control the switching of the contact portion connected to the side of the track only when the switch portion 600 is correctly connected to the first power supply portion 110 and the second power supply portion 210 on the side of the track.

[0044] The movable part 300 is connected to each of the two contact portions in the curved portion of the track. Then, when the track slides along either extension, the switch part 600 determines via a voltage sensor whether the magnetic part is correctly connected to the first power supply part 110 or the second power supply part 210 extending on the track side in the direction of the magnetic part's sliding. When the magnetic part is correctly connected to the first power supply part 110 or the second power supply part 210 on the track surface extending in the direction of the magnetic part's sliding, the connection between the track side extending in the direction of the magnetic part's non-sliding and the first power supply part 110 or the second power supply part 210 is interrupted. When the contact portion is not correctly connected to the first power supply part 110 or the second power supply part 210 on the track side extending in the direction of the magnetic part's sliding, an error signal can be sent to the passenger, and thereafter, the sliding of the movable part 300 can be restricted, such that the existing connection between the track surface and the first power supply part 110 or the second power supply part 210 is maintained, and the contact portion of the movable part 300 with the first power supply part 110 or the second power supply part 210 on the track side is not released.

[0045] Figure 5 This diagram illustrates a spring portion disposed in a first contact portion or a second contact portion in a sliding unit for a vehicle according to an embodiment of the present disclosure. In the sliding unit for a vehicle according to an embodiment of the present disclosure, a spring portion 450 may be disposed in the first contact portion 410 and the second contact portion 420, and the spring portion 450 may apply a spring force to the first contact portion 410 and the second contact portion 420, such that the first contact portion 410 and the second contact portion 420 are attached to the first power supply portion 110 and the second power supply portion 210. Because the contact portion disposed in the movable member 300 contacts the first power supply portion 110 and the second power supply portion 210 disposed on the side of the track to receive power, the power is interrupted if the contact with the first power supply portion or the second power supply portion is released. Therefore, the spring portion 450 can prevent the release of contact and the interruption of power.

[0046] Figure 4This is a side view showing a movable component on a track in a sliding unit for a vehicle according to an embodiment of the present disclosure. In the sliding unit for a vehicle according to an embodiment of the present disclosure, the movable component 300 may have a rectangular frame shape, a magnetic portion 320 is disposed in the interior space of the frame, and a first contact portion 410 and a second contact portion 420 may be disposed on the frame to face a first power supply portion 110 and a second power supply portion 210 of the track. Contact portions are disposed on each surface of the rectangular frame such that a total of four contact portions are provided, and the contact portions contact the first power supply portion 110 and the second power supply portion 210 on the side of the track to be connected to the magnetic portion 320 via wiring, thereby supplying power to the magnetic portion 320.

[0047] Because the sliding unit for vehicles according to embodiments of this disclosure employs a locking mechanism using a magnetic portion 320, the structure of the sliding unit is simple, the space for the track is minimized, and this space can be effectively utilized within the vehicle interior. Specifically, existing track locking mechanisms typically include types using lead screws and forked types, and when the seat is locked in this manner, the track height has an additional length of 47mm or 57mm. When the track height is too large, the track occupies most of the limited space on the vehicle floor, making it difficult to utilize space effectively. Therefore, the sliding unit for vehicles according to embodiments of this disclosure employs a new locking mechanism that uses a magnetic portion 320 to achieve a slender track structure with a track height of approximately 30mm.

[0048] Meanwhile, the guide rail of the sliding unit for a vehicle according to an embodiment of the present disclosure has a bottom surface, opposing side surfaces, and a top surface, and the first power supply portion 110 and the second power supply portion 210 can be disposed along the guide rail on the corresponding side surfaces of the guide rail. In the sliding unit for a vehicle according to an embodiment of the present disclosure, a fixed portion 310 formed of a magnetically flowing material is disposed on the bottom surface of the rail, and a magnetic portion 320 disposed in the movable member 300 is disposed facing the fixed portion 310 to form a magnetic circuit. In the sliding unit for a vehicle according to an embodiment of the present disclosure, when the magnetic portion 320 and the fixed portion 310 jointly form a magnetic circuit, the magnetic portion 320 can be locked with the fixed portion 310, and when the magnetic circuit is formed only in the magnetic portion 320, the magnetic portion 320 can be unlocked from the fixed portion 310.

[0049] The magnetic portion 320 may include: a fixed permanent magnet having an annular shape, contacting the fixed portion 310, and disposed on the side of the magnetic portion 320 close to the fixed portion 310; and an electromagnet disposed on the side of the magnetic portion 320 opposite to the fixed portion 310, and the magnetic portion 320 can be locked to or unlocked from the fixed portion 310 as the polarity of the electromagnet changes. In other words, the magnetic portion 320 applies a current to the electromagnet to form a magnetic circuit, and the magnetic circuit formed in the magnetic portion 320 changes as the polarity of the electromagnet changes.

[0050] Specifically, when current is applied to the electromagnet, and the polarity of the electromagnet at the adjacent portion of the fixed permanent magnet is formed to have the same polarity as the adjacent fixed permanent magnet, a magnetic circuit is formed to pass through the magnetic portion 320 and the fixed portion 310 together. Therefore, the magnetic portion 320 is locked to the fixed portion 310, and the movable member 300 is fixed to the track. Specifically, when current is applied to the electromagnet, and the polarity of the electromagnet at the adjacent portion of the fixed permanent magnet is formed to have the opposite polarity to the adjacent fixed permanent magnet, a magnetic circuit is formed to pass through only the magnetic portion 320 and not through the fixed portion 310. Therefore, the magnetic portion 320 is unlocked from the fixed portion 310, and the movable member 300 is released from the track.

[0051] Furthermore, when current is applied to the electromagnet to form a magnetic circuit, after the magnetic part 320 locks with or unlocks from the fixed part 310, the pre-formed magnetic circuit is maintained even when the application of current stops, and the magnetic part 320 remains locked with or unlocked from the fixed part 310. Therefore, when a locking mechanism is implemented in the track using the magnetic part 320, power consumption can be minimized because current must only be supplied when the magnetic part 320 is locked or unlocked.

[0052] Meanwhile, in the sliding unit for a vehicle according to an embodiment of the present disclosure, a plurality of bearing portions 510, 520, and 530 are disposed on the outer surface of the movable member 300. The bearing portions 510, 520, and 530 are supported on the bottom, side, or upper surface of the track for rotation, and the left / right or up / down position of the movable member 300 can be adjusted by the bearing portions 510, 520, and 530 when the movable member 300 slides. Furthermore, in the sliding unit for a vehicle according to an embodiment of the present disclosure, a track cover 150 extending along the track and having a slit hole can be disposed on the upper surface of the track, and a connecting portion 330 passing through the slit hole and connecting to the movable member 300 can be disposed on the upper side of the track cover 150.

[0053] Specifically, in the sliding unit for a vehicle according to an embodiment of the present disclosure, the bearing portion is a side bearing 510 located at the apex of a movable member 300 having a rectangular frame shape. The left / right position of the side bearing 510 is supported by the side of the track, and the left / right position of the movable member 300 can be adjusted by the side bearing 510 when the movable member 300 slides. A total of four side bearings 510 are arranged at the apex of the side of the rectangular frame and are supported by the side of the track for rotation. When the movable member 300 slides, the lower position of the movable member 300 can be adjusted, and left / right eccentricity of the movable member 300 can be prevented.

[0054] Furthermore, in the sliding unit for a vehicle according to an embodiment of the present disclosure, the bearing portion is an upper bearing 520 located on the upper surface of a movable member 300 having a rectangular frame shape. The upper bearing 520 is supported by the upper surface of the track, and the upper position of the movable member 300 can be adjusted by the upper bearing 520 when the movable member 300 slides. A total of four upper bearings 520 are disposed at the vertices of the upper surface of the rectangular frame and supported by a track cover covering the upper surface of the track for rotation, and the upper position of the movable member 300 is adjusted when the movable member 300 slides.

[0055] In the sliding unit for a vehicle according to an embodiment of the present disclosure, the bearing portion is a lower bearing 530 located on the lower surface of a movable member 300 having a rectangular frame shape. The lower position of the lower bearing 530 is supported by the lower surface of the track for rotation, and the lower position of the movable member 300 can be adjusted by the lower bearing 530 when the movable member 300 slides. A total of four lower bearings 530 are disposed at the apex of the lower surface of the rectangular frame and are supported by the lower surface of the track or the fixed portion 310 for rotation, and the lower position of the movable member 300 is adjusted when the movable member 300 slides. Therefore, the movable member 300, the magnetic portion 320, and the multiple bearing portions 510, 520, and 530 occupying minimal space are located in the interior space of the track, and the movable member 300 is connected to the connecting portion 330 passing through a slit hole provided in the track cover 150 to achieve a simple and slender track.

[0056] Figure 6 This is a diagram illustrating a sliding unit for a vehicle according to an embodiment of the present disclosure, comprising a track having a rectangular annular shape and movable components located on the track. In the sliding unit for a vehicle according to an embodiment of the present disclosure, the track has a rectangular annular shape and is disposed on the floor of the vehicle, and a seat, console, or table is coupled to a connecting portion 330 such that the seat, console, or table can slide forward and backward, and left and right, on the floor of the vehicle.

[0057] In the sliding unit for a vehicle according to an embodiment of the present disclosure, multiple wires having positive and negative electrodes are connected to the first contact portion 410 and the second contact portion 420, and the wires pass through a slit hole from the upper end of the movable part 300 to connect to a seat, console, or table, and the first contact portion 410 or the second contact portion 420 can supply power to the seat, console, or table when the first power supply portion 110 and the second power supply portion 220 are contacted.

[0058] Therefore, when the movable part 300 slides forward and backward and left and right along the track, the seat, console, or table is coupled to the connection portion 330 connected to the movable part 300 to move with the movable part 300, and can be locked or unlocked with the fixed portion 310 by using the magnetic portion 320, and can be electrically connected to four contact portions on the side of the movable part having a rectangular frame shape, which is electrically connected to the first power portion 110 and the second power portion 210 on the corresponding side of the track having a rectangular ring shape connected to the vehicle power supply, to receive and utilize electricity.

[0059] Meanwhile, in the sliding unit for a vehicle according to an embodiment of the present disclosure, the track has a rectangular ring shape and is disposed on the vehicle floor, and the movable member 300 has a rectangular shape and can slide forward and backward, and left and right on the vehicle floor. Furthermore, in the sliding unit for a vehicle according to an embodiment of the present disclosure, a seat, console, or table is coupled to the movable member 300, such that the seat, console, or table can slide forward and backward, and left and right on the vehicle floor.
