Description

Vehicle seat displacement device using a magnetic body holding device and a vehicle having the same {apparatus for moving seat of vehicle using magnetic body holding means and vehicle having the same}

The present invention relates to a vehicle seat and a vehicle having the same, and more specifically, a vehicle seat displacement device and a vehicle having the same, which are in charge of the displacement operation of the vehicle seat and enable switching between a displaceable and an impossible state It is about.

The vehicle is made up of vehicle seats for drivers and passengers. For vehicles used by a large number of unspecified people, such as public buses, seats are usually made to have standard and standard sizes and postures, and often do not take into account the individual body size or characteristics of each occupant.

In the case of a private vehicle, the seat is made to have a standard size, but it can also be adjusted to a separate seat size for the driver or passenger, or by shifting the position of the seat itself or changing the relative position of the seat components within the standard condition. It is also possible to adjust it to fit your body size or comfortable posture.

However, in some special vehicles, it is difficult to think of cases where seats can be removed, adjusted, and adjusted in addition to being made on demand. In particular, in a car or a van, the front driver's seat and the passenger seat are basically made to face the front, and some front-to-back parallel movement and back or seat angle adjustment can be made sufficiently, but it is difficult to think if it is fully adjusted to the back or left and right. .

For these reasons, in the existing vehicle, the vehicle seat is difficult to have a change of direction or to move left and right, and it is difficult to find a configuration for easily adjusting or moving the vehicle seat.

However, with the development of artificial intelligence in the future, vehicle technology is developing with autonomous driving as an important theme, and in this case, it is not necessary to point the driver's seat or passenger's seat forward, and in the case of driving while facing the rear passengers It will occur a lot, and in the case of a camper, the inside of the vehicle becomes a living space, so there is a high possibility of using the space while turning the front seats back to see the interior space.

In this case, how easy it is to perform displacement movements such as rotation or linear movement of the vehicle seat will be an important technical key, and how securely the vehicle seat can be coupled to the vehicle with this variability will be an important technical matter. For this, a holding method or apparatus for fixing the vehicle seat displacement to the vehicle becomes important.

On the other hand, as a device for fixing an object, a magnetic substance holding device is a device for fixing a magnetic substance such as iron using a magnetic force. The magnetic material holding device is used in a mold clamping device for an injection machine or a press machine, or a chuck for fixing a work piece of a machine tool. The conventional magnetic material holding device uses an electromagnet, and in this case, there is a problem that it is expensive to fix the object in a long-term and stable manner because a current must be continuously flowed to fix the object.

A magnetic holding device using a permanent electromagnet (PERMANENT ELECTRO MAGNET) is disclosed in U.S. Patent No. 4,956,625. In this case, power is required only when the magnetic object is held and when the holding is released, so that power is not consumed when the object is to be fixed for a long time. Referring to Figure 1, the conventional magnetic holding device using a permanent electromagnet yoke (1), pole piece (Pole piece, 2), intermediate pole member (Intermediate pole member, 3), permanent magnet (4), secondary permanent It consists of a plurality of modules consisting of a magnet (5), a lead wire (6) wound around a permanent magnet (4), and a high-voltage power supply (7).

In this configuration, the permanent magnet 4 uses an alico magnet capable of magnetization and demagnetization as a primary permanent magnet 4 by applying a high current to a conductor wire wound around it. Alyco magnets are known as magnets that can be magnetized and demagnetized with the lowest current among permanent magnets. The holding device instantaneously applies a high current to the lead wire (6) wound around the main permanent magnet (4) located between the pole piece (2) and the bottom plate of the yoke (1) to adjust the polarity of the main permanent magnet (4). By converting, the object 9 which is a magnetic substance is held (fixed) or released (fixed) by magnetic force.

Korean Patent Registration No. 10-1125280 discloses several magnetic material holding devices that combine permanent magnets and electromagnets. For example, here, as shown in Fig. 2, a method of connecting the gap between the pole piece and the yoke with the magnetic field of the electromagnet by generating a holding force with the permanent magnet module without supplying current by placing a fine gap between the pole piece and the yoke. This is disclosed.

This holding device includes a yoke 11, a pair of pole pieces 15 disposed inside the yoke 11, a plurality of permanent magnets 17 disposed between the yoke 11 and each pole piece 15, It includes an electromagnet 18 and an intermediate permanent magnet 30 disposed between the two pole pieces 15, and an electromagnet control device 24 for supplying electric current to the electromagnet 18.

The yoke 11 has a base plate 12 and a plurality of side plates 13 disposed at the edges of the base plate 12. The base plate 12 and the side plate 13 may be integrally formed. The yoke 11 is made of a ferromagnetic material that is magnetized in the direction of the magnetic field when a magnetic field is applied from the outside.

The first and second pole pieces 15 are arranged to be spaced apart from the yoke 11 inside the yoke 11. Each pole piece 15 has a holding surface 16 for holding a magnetic body not shown here. The pole piece 15 is made of a ferromagnetic material like the yoke 11. The pole piece 15 is supported by the support member 29 and is spaced apart from the bottom plate 12 of the yoke 11. The support member 29 may be made of various materials that are not affected by magnetic fields such as plastic. The support member 29 supports the pole piece 15 and at the same time serves to prevent the magnetic force line passing through the pole piece 15 from being transmitted to the yoke 11.

The plurality of permanent magnets 17 are disposed between the side plates 13 of the yoke 11 and the remaining side surfaces where the intermediate permanent magnets 30 of the pole piece 15 are not in contact. The plurality of permanent magnets 17 are in contact with the pole piece 15 with the same pole as the middle permanent magnet 30 is in contact with. That is, the N pole of the permanent magnets 17 is in contact with the pole piece 15 in contact with the N pole of the intermediate permanent magnet 30, and the permanent magnet is in the pole piece 15 in contact with the S pole of the intermediate permanent magnet 30. The S pole of the field 17 is in contact.

The electromagnet 18 includes an iron core 19 and a coil assembly 20 surrounding the iron core 19. The coil assembly 20 is composed of a coil 21 for supplying current and a bobbin 22 which is a non-conductor surrounding the coil 21. The electromagnet 18 is between the two pole pieces 15 such that one end of the iron core 19 contacts the side of the first pole piece 15 and the other end of the iron core 19 faces the side of the second pole piece 15. Is placed. The other end of the iron core 19 is spaced a certain distance from the side of the second pole piece 15. The gap G between the iron core 19 and the second pole piece 15 is supplied with current to the coil 21 so that when the iron core 19 is magnetized, the magnetic force line coming out of the iron core 19 is the second pole piece 15 ).

Separation for supporting the electromagnet 18 with the iron core 19 spaced apart from the second pole piece 15 between the second pole piece 15 and the electromagnet 18 adjacent to the other end of the iron core 19. The member 23 is arranged. The separating member 23 may be made of various materials such as plastic that are not affected by the magnetic field. Of course, the separation member 23 may be omitted, in which case the end of the bobbin 22 of the coil assembly 20 comes into contact with the side of the second pole piece 15.

The registered patent also discloses a holding device having a holding state and a release state as shown in Figs. 3 and 4, which are slightly modified. Here, if the current is supplied to the electromagnet 18 and both ends of the iron core 19 are magnetized to become the same pole as the poles of the permanent magnets 17 and the intermediate permanent magnets 30 contacting the pole pieces 15 contacting them, respectively. , The magnetic force lines of the permanent magnet 17 and the intermediate permanent magnet 30 and the magnetic force lines of the electromagnet 18 pass through the holding surfaces 16 of each pole piece 15 in the same way. At this time, a holding force is generated on the holding surface 16 of each pole piece 15 so that the magnetic body W is held on these holding surfaces 14 and 16.

On the other hand, the current is supplied to the electromagnet 18 so that both ends of the iron core 19 are poles opposite to the poles of the permanent magnets 17 and the intermediate permanent magnets 30 contacting the pole pieces 15 respectively contacting them. When magnetized, the direction of the magnetic force lines from the permanent magnet 17 and the intermediate permanent magnet 30 is bent. That is, the magnetic force line returns to the middle permanent magnet-first pole piece-iron core-second pole piece-middle permanent magnet. At this time, the magnetic force lines coming out of the permanent magnet 17 and the intermediate permanent magnet 30 do not pass through the holding surface 16 of the pole piece 15, and the holding force is removed from these holding surfaces 16.

This magnetic holding device can be applied to a variety of products regardless of the structure due to the use of relatively low current, and high current, unstable performance, heat generation, coil damage, safety, size, very high price, narrow application fields of the conventional permanent electromagnet technology Many problems such as can be solved.

The present invention aims to provide a vehicle seat displacement device and a vehicle equipped with the vehicle seat displacement device which is a means for easily changing the direction and moving the position in the above-mentioned conventional vehicle seat and stably maintaining the vehicle seat in a stable state. do.

An object of the present invention is to provide a vehicle seat displacement device having a configuration that can easily solve the hassle and deterioration of mechanical operation and a vehicle having the same.

The vehicle seat displacement device of the present invention for achieving the above object is a displacement means for rotational movement or linear movement corresponding to a direction change, and a release state in which such displacement is possible and a holding state in which the vehicle seat is stably fixed. It is provided with a magnetic material holding device to facilitate the switching, and the magnetic material holding device is characterized in that it does not require a power connection in order to maintain the holding state and the released state, and to make a temporary power connection only when the state is switched between these states. .

In the present invention, the magnetic substance holding device is provided with a permanent magnet that can be changed depending on the polarity of the DC power supply that is temporarily connected to the permanent magnet that is kept constant irrespective of the power connection, and the magnetic force or magnetic field of the magnetic substance holding device is It may be caused by the superposition of the magnetic field or magnetic field of these individual magnets. For example, in the vehicle seat holding state, the stimulation of the permanent magnet and the permanent electromagnet acts in the direction of increasing the magnetic force, and in the released state, the stimulation of the permanent magnet and the permanent magnet acts in the direction of canceling the magnetic force.

In the present invention, the vehicle seat displacement device may be made of a slide block and a rail as a parallel moving means and an axis as a rotating moving means. For example, an axial support for rotatably supporting one side of the vehicle seat shaft is installed on the floor of the vehicle, and a rail for linear movement is coupled to the other side of the shaft, and the vehicle seat is fixed on a slide block moving along the rail. Can have

The magnetic substance holding device of the present invention is installed in a slide block, and the magnetic substance holding device has a hold button for a holding state and a release button for a release state, and when the hold button is pressed, the slide block is in close contact with the rail by magnetic force, so that the slide cannot be moved. In the state, the rail and the rail-mounted shaft top plate are ferromagnetic, and are also ferromagnetic. It can become a state. Of course, when the release button is pressed, the magnetic field by the slide block constituting the magnetic material holding device is eliminated, and even if it is a ferromagnetic material, the rails, the upper shaft plate, and the rotation control plate do not have the adhesive force. All rotational movements are possible. At this time, in order to facilitate movement, when a magnetic field is not applied through a spring device between the shaft top plate and the rotation control plate, the two parts may be finely spaced.

Of course, the magnetic body holding device may be installed on the vehicle body side such as a rotation control plate instead of a slide block. Even in this case, if the shaft top plate, rails, and slide blocks are all ferromagnetic, the release state and the holding state will be substantially the same as in the above embodiment.

According to the present invention, the displaceable state or the unlocked state and the fixed state or the holding state of the vehicle seat of the vehicle seat can be selected through the release button or the hold button of the magnetic substance holding device, and when the release state is selected, the vehicle seat is easily attached to the vehicle bottom surface. The axis can be rotated using an axis or linearly moved using a rail.

According to the present invention, it is applied in an autonomous vehicle or a camping car having a large need to turn a driver's seat or a passenger seat, which is a front seat, so that it is possible to easily and conveniently shift the seat direction and move the position by using a magnetic body holding device.

Hereinafter, the present invention will be described in more detail with reference to drawings.

FIG. 5 is a view of the rotation and linear movement displacement of the vehicle seat 200 between the seat plate frame of the vehicle seat (hereinafter simply referred to as the vehicle seat 200 or the seat plate) and the vehicle floor 300 to which the vehicle seat is coupled. It is a sectional view showing one embodiment of the vehicle seat displacement device of the invention.

The vehicle seat displacement device comprises a shaft 140 for rotational displacement, a rail 120 for linear displacement, and a slide block 110. And the shaft support 150 for supporting the lower end of the shaft 140 is installed on the vehicle floor 300. The shaft support 150 is made of a bearing so that the shaft 140 can rotate smoothly.

Next to the shaft support 150, a circular rotation control panel 160 is also fixed to the vehicle floor 300. A plurality of gear teeth in the radial direction or a concave convex structure equivalent thereto are formed in the peripheral portion of the rotation control panel 160.

On the other hand, the top of the shaft 140 is fixed so that the disk 130 of a certain thickness is integral with the top of the shaft 140. For fixing, a coupling means such as a bolt nut or rivet, welding, adhesive, etc. can be used. In the peripheral portion of the lower surface of the original plate 130, a gear tooth structure that can be engaged with and engaged with the gear tooth structure of the rotation control plate 160 is formed.

6 is a conceptual diagram illustrating the structure of the gear teeth 161 of the rotation control plate 160 and the original plate 130.

Small gear teeth 161 made of radial mountains and valleys are provided on both sides. Here, the ends of the hills and valleys have round ends rather than a sharp angle, so that the relative rotational movement is possible in a gentle approaching state where the rotation control panel 160 and the disk 130 are not engaged.

Here, it is assumed that the gear teeth 161 are formed on the mutually opposing surfaces between the original plate 130 and the rotation control plate 160, but it is also possible that the opposing surfaces are formed of friction surfaces that are easy to friction instead of gear teeth.

The rail 120 is fixedly coupled to the upper surface of the original plate 130. Both ends of the rail 120 may extend in a straight line so as to slightly deviate from the upper surface of the disk 130.

The slide block 110 is coupled to the rail 120. The slide block 110 may move linearly within the installation range of the rail 120. However, a stopper (not shown) is installed at both ends of the rail 120 so that the slide block 110 does not deviate from the range of the rail 120. The stopper is rigidly formed to withstand a situation such as a vehicle collision or a sudden brake.

The vehicle seat 200 is fixed to the upper surface of the slide block 110. For fixing the vehicle seat 200, various means such as the above-mentioned welding, a coupling member such as a bolt nut, an adhesive may be used. However, strong coupling means should also be used here to withstand vehicle collisions.

When the contact surface between the slide block 110 and the rail 120 is in close contact by gravity and external force, the friction force is large, and thus cannot be easily moved linearly. When the contact force of the contact surface is alleviated due to the absence of external force, the roughness that can be moved relatively easily or It may be formed of a friction surface, and the gear teeth 161 that form the same teeth as the gear teeth 161 between the rotation control panel 160 and the disk 130 may be linearly formed. For example, a plurality of gear teeth arranged in a linear manner, such as gear teeth of a recreational gear, may be provided.

In addition to this morphological configuration, the components between the slide block 110 and the rotation control panel 160 are all made of a strong magnetic material, so that when a magnetic field is formed on an adjacent object, it is made to act as a magnet. Then, one of these or a surrounding object coupled to them is formed of a magnetic field holding device for forming a magnetic field or acting on a magnetic force as necessary.

For example, it is assumed here that the slide block 110 is made of a magnetic material holding device. The original plate 130 and the rail 120 are both ferromagnetic, and when the magnets are combined, they act as a kind of magnet. The slide block 110 forms a stimulus as long as it generates a strong magnetic field in the holding state. For example, in the holding state, when the lower block 111 of the slide block 110 becomes a strong N pole, the rail 120 acts like an S pole, and the lower surface of the disk opposite the rail acts like an N side.

The rotation control panel 160 fixed to the vehicle floor 300 is also a ferromagnetic material, and its upper surface acts like an S pole opposite to the lower surface of the disk 130.

In this relationship, the slide block 110 and the rail 120, the original plate 130 and the rotation control plate 160 are fixed by a strong magnetic force to each other, and the combined surface of the slide block 110 and the rail 120, The corresponding surfaces of the original plate 130 and the rotation control plate 160 form a relatively difficult state to move due to friction or meshing.

Eventually, the slide block cannot move linearly along the rail, and the original plate cannot be rotated relative to the rotation control plate, thereby preventing the shaft from rotating, and eventually the vehicle seat is stable without linear movement and rotational movement of the vehicle seat. State.

Conversely, when the release button 115 of the slide block 110, which is a magnetic holding device, is pressed so that the lower surface of the slide block 110 can no longer form a magnetic field, the slide block 110, the rail 120, and the original plate 130 The rotation by the magnetic force between the rotation control panel 160 is eliminated, and in this state, the degree of sliding movement between the slide block 110 and the rail 120 becomes possible, and the lower surface of the original plate 130 and the rotation control panel 160 ) Even if there is a gear value of the upper surface (correspondence surface), it is not in close contact and is almost spaced, so if a certain amount of force is applied, rotation can be easily performed.

Therefore, the user of the vehicle seat 200 can rotate arbitrarily in the unlocked state to rotate and move along the rail 120, so combination of rotation and parallel movement is allowed for each vehicle seat 200 as shown in FIG. Seats can be adjusted to any desired position and orientation within the vehicle within the specified range.

In FIG. 7, the small circle at the position of each vehicle seat 200 shows the axis 140, the large circle around the axis 140 shows the disk 130 at the top of the axis, the rectangular form shows the rail 120, and the large circle of the virtual line. The circle represents the vehicle seat 200 or its seat.

At this time, the small square 230 on the virtual line of the seat plate indicates the front direction of the seat. Here, the seat front direction is the rail 120 while the vehicle seat 200 is moved along the rail 120 radially from the axis 140. ).

In this state, when the hold button 113 is pressed again, the above-described state is achieved, and the components are in close contact with each other, so that a stable seating is possible in a state in which rotation and movement are impossible.

If the gear value of the lower surface of the original plate 130 and the corresponding surface of the rotation control plate 160 is difficult to rotate even when it is released, or if the friction between the contact surface between the rail 120 and the slide block 110 is high, a spring 133 therebetween By placing a cushioning means such as), the gear teeth are engaged with each other, the friction surface is kept in close contact, and rotation or linear movement can be made easier. Of course, in this case, in the holding state, the magnetic force is sufficiently large so that the spring 133 is compressed and enters into the space 131 holding the spring 133 so as not to interfere with the meshing or friction action.

On the other hand, the slide block 110 and the shaft 140 connected to the vehicle seat 200 may be installed by an electric motor operated by means such as an electric motor (not shown) installed in the vicinity, and a specific configuration thereof Since the seat backing is possible through general mechanical design, such as the motion of moving the seat board electrically, it will not be described in detail any more.

In another embodiment of the present invention, the magnetic material holding device may be installed on the vehicle body side such as the rotation control panel 160 instead of the slide block 110. Even in this case, if the shaft 140, the disk 130, the rail 120, and the slide block 110 are all ferromagnetic, the release state and the holding state will be substantially the same as in the above embodiment.

For example, when the upper surface of the circular rotation control panel 160 in the holding state becomes a strong N pole, the lower surface of the original plate 130 is attracted by the magnetic force to be in close contact, and the lower surface of the original plate 130 has an S pole. The rail 120 integrally coupled to the original plate 130 acts like an N-pole, and the lower surface of the slide block 110 in contact with the rail 120 acts like an S-pole, so that the whole has a strong adhesion by magnetic force. Achieve.

Therefore, even here, the contact surface of the rail and the sliding block cannot be moved due to strong friction, and the original plate cannot be rotated with respect to the rotation control plate, so that the vehicle seat is in a stable engagement state in which neither rotational displacement nor linear displacement is achieved.

In this state, when the release button connected to the rotation control panel is pressed to be released, for example, if the magnetic field or magnetic field is formed by superimposing the magnetic field of the permanent magnet and the permanent magnet of the magnetic substance holding device, the polarity of the permanent electromagnet is caused by temporary current flow. As the magnetic field of the permanent magnet and permanent magnet changes, the magnetic field of the permanent magnet and the permanent magnet cancels out and becomes insignificant. It becomes a state.

Therefore, by placing the vehicle seat 200 in a desired position and direction within a possible range and pressing the holding button 113, a strong magnetic field superimposed in the magnetic substance holding device is formed, and the upper surface of the rotation control panel 160 again has a strong N pole, The rest of the ferromagnetic elements are brought into close contact by magnetic force, thereby making the vehicle seat 200 stable.

Fig. 8 shows a sectional view in an embodiment configuration that makes the vehicle seat direction more free than the embodiment of Fig. 5;

Here, the second shaft 210 is installed at the bottom of the seat plate to allow relative rotation between the slide block 110 'and the seat plate of the vehicle seat 200', and the second shaft 210 passes through the slide block 110 '. The hall and the shaft support (not shown) around the hall were installed.

Then, instead of the slide block 110 ', a magnetic material holding device having a hold button 223 and a release button 225 was installed on the seat plate of the vehicle seat 200'. The configuration of the lower part is not repeated because the same configuration has been described in the embodiment of FIG. 5.

In relation to the fact that the second shaft 210 (not shown) such as in the vehicle floor 300 is installed on the slide block 110 ′ to rotatably support the lower portion of the second shaft 210, in this state, the slide block ( The rotation of the second shaft 210 and the vehicle seat 200 'with respect to 110') may be performed purely by a conventionally known mechanical action, but here the holding and release by magnetic force is changed by changing the installation position of the magnetic substance holding device. To lose.

The mechanical action between components other than that of the magnetic substance holding device and the mechanical configuration for these actions can also be implemented through various known mechanical devices.

In addition, the holding button and the release button are formed on the seat plate of the vehicle seat close to the magnetic field generating unit of the magnetic substance holding device, but these can be said to be a kind of switch, so it can be said to be a kind of switch. It is also possible to install with a function button.

The power for state switching in the magnetic holding device may be used in the form of a separate battery installed close to the magnetic holding device, or may be used by connecting the vehicle battery power. In the case of the above-described embodiments in which the magnetic material holding device is installed in a displaceable portion such as a vehicle seat rather than a fixed part such as a vehicle body floor, a coil spring-type electric wire that is easy to expand and contract electric wires may be used so that power connection can be continued when the vehicle seat is moved. .

If the rotational configuration between the seat plate and the slide block 110 'is substantially the same as the configuration between the original plate 130 and the rotation control plate 160, it is also possible to use a simple friction surface instead of the meshing surface.

Here, when the magnetic body holding device of the seat plate is held in the same manner, all of the sliding blocks 110 ', the rail 120, the disk 130, and the rotation control plate 160 below the lower surface of the seat plate are ferromagnetic and each other by magnetic force. Since it is in close contact, it is difficult to rotate or linearly move due to slippage on the friction surface or the mating surface, so it is possible to stably fix the vehicle seat in a close contact state.

When the release button 225 is pressed to temporarily flow current and the direction of the permanent electromagnet changes and the magnetic field generated by the magnetic material holding device cancels out and is erased, the adhesion between them is relaxed or the restoring force of the spacer such as a spring between these elements Because it is spaced by, it becomes possible to rotate and move linearly.

Therefore, in this release state, the shaft 140 is rotated, the slide block 110 'is moved along the rail 120, and the vehicle seat 200' is rotated again using the second shaft 210, in the desired vehicle. In one state to have the position and direction, the hold button 223 is pressed again to switch to the holding state to fix the position and direction of the vehicle seat 200 '.

Through this configuration, the position and direction of the vehicle seat in the vehicle can be changed more freely, and such an operation is simply performed through a temporary button operation of the magnetic substance holding device, and electrical energy for maintaining the holding state or the unlocked state. No continuous input is required.

9 is a conceptual diagram schematically showing a state in which the vehicle seat can be rotated and moved in the same embodiment as in FIG. 8.

In the conceptual diagram of FIG. 7 for the embodiment of FIG. 5, the vehicle seat is already described

In the state in which the vehicle seat moves radially from the shaft 140 along the rail 120, the front direction of the vehicle seat is fixed to the same direction as the movement direction through the rail 120, but in the embodiment shown in FIG. 8, the slide block and Since the fixing between the seat plates is a rotatable fixing, the seat can be rotated again at each position in the vehicle moved along the rail so that it can be directed in any direction. Therefore, in FIG. 9, a small square 230 indicating the front of the sheet is displayed for four rotational positions indicating each direction in the circle of the virtual line.

In the above, the present invention has been described through limited embodiments, but the present invention is merely illustrative to help understanding of the present invention, and the present invention is not limited to these specific embodiments. For example, in the specification of the present invention, only a few examples of the magnetic substance holding device are mentioned, but as long as the basic function of the holding device for fixing the magnetic body using magnetic force is implemented, various magnetic substance holding devices known in the art can be used.

Therefore, a person having ordinary knowledge in the field to which the present invention pertains can implement various modifications and application examples based on the present invention, and it is natural that such modifications and application examples belong to the appended claims.
