Description

Technical Field

[0001] This disclosure relates to a detachable and connectable smart mobility configured to unfold or retract and, when unfolded, allow passengers to board. Background Technology

[0002] Recently, urban air mobility (UAM), dedicated vehicles (PBV), and mobility hubs (mobile transfer centers) have attracted much attention as future autonomous transportation solutions, leading to the introduction of various concepts and the commencement of initial technology development in these areas.

[0003] Specifically, a PBV is a ground transportation system based on electric vehicles, but instead of moving by wheels, it moves via electric wheels that can move freely in 360 degrees. PBVs go beyond simple transportation, offering passengers the customized services they need to reach their destinations. In addition to being used as city shuttles, PBVs can be designed to reflect individualized functions and serve a wide range of spaces, from leisure spaces such as restaurants, cafes, or hotels to basic social facilities such as hospitals and pharmacies. For this purpose, the interior of the vehicle can be customized using modular products tailored to specific uses.

[0004] However, the manufacturing process of a moving body, including a PBV, is complex due to the numerous components that make up the vehicle body. Specifically, molds must be manufactured to produce the main body that constitutes the vehicle body, involving numerous welding and assembly processes, and production lines must be configured for each process.

[0005] In particular, because PBVs are designed to reflect personalization trends and cater to diverse preferences, challenges have arisen in manufacturing the doors used for passenger boarding and alighting. For example, to manufacture the doors, the opening and closing structure is created by segmenting the exterior of the vehicle body, but this segmentation reduces rigidity and causes interference with other components.

[0006] The above description of the background art is intended only to help understand the background of this disclosure and is not intended to imply that this disclosure falls within the scope of prior art known to those skilled in the art. Summary of the Invention

[0007] This disclosure provides a detachable and connectable smart mobile body configured to expand or retract while ensuring overall rigidity, wherein the interior is closed when retracted and an entrance is provided when expanded to allow passengers to board the smart mobile body.

[0008] The technical subject matter involved in this disclosure is not limited to the above-described technical subject matter, and other technical subject matter not explicitly stated can be readily understood by those skilled in the art from the following description. In view of the above, a separable and connectable intelligent mobile body according to this disclosure includes: a vehicle body having an interior space and an opening located on one or both sides of the vehicle body; a drive unit including a closure component and a drive module, wherein the closure component is configured to mate with the opening of the vehicle body, and the drive module is mounted to the closure component and configured to move the drive unit; a plurality of fixed frames located on an inner or outer surface of the vehicle body and extending in a longitudinal direction; an extension frame detachably connected to the closure component, wherein each extension frame is connected to a corresponding fixed frame and configured to slide along the fixed frame; and a fixing unit configured to selectively fix the extension frame to the closure component when the extension frame is positioned to contact the closure component.

[0009] The vehicle body includes an opening on one side, and the vehicle body drive module is located on the other side of the vehicle body. Multiple fixed frames are spaced apart from each other along the periphery of the inner surface of the vehicle body and each has a hollow hole in the longitudinal direction. Extending frames are arranged in the same number as the fixed frames and each extends in the longitudinal direction to be inserted into the hollow hole.

[0010] The length of the extension frame is equal to or greater than the length of the fixed frame, such that when the extension frame is inserted into the hollow hole, the end of the extension frame is partially exposed from the fixed frame.

[0011] The extension frame further includes a slider connected to the fixed frame and designed to reciprocate linearly along the fixed frame. The slider is equipped with a sliding or rolling function. Each of the fixed frames includes: a main support extending longitudinally, fixed to the vehicle body, and having a hollow hole; and a secondary support extending from the main support in the circumferential direction of the vehicle body and fixed to the vehicle body.

[0012] Each fixing unit includes a fixing component and a connecting component. The fixing component is disposed on one of the closing component and the corresponding extension frame, and the connecting component includes: a pole component disposed on the other of the closing component and the extension frame; a first magnet rotatably disposed in the pole component; a second magnet spaced apart from the first magnet and fixed to the pole component; and an electromagnet configured to generate magnetic force when an electric current is applied.

[0013] The fixing component is made of a magnetically attractive material, including steel, and the first magnet and the second magnet are each configured using permanent magnets so that the direction of the magnetic field changes according to the rotational position of the first magnet.

[0014] An electromagnet is disposed between a first magnet and a second magnet in the pole component and is configured to adjust the rotational position of the first magnet by generating magnetic force.

[0015] In the process of generating magnetic force, the electromagnet creates opposite polarities in the directions in which the first magnet and the second magnet face each other.

[0016] Each fixing unit includes: a first contact and a second contact, respectively disposed on the enclosed component and the extended frame; a pole unit, including a first pole component and a second pole component, the first pole component having a first permanent magnet and extending toward the first contact, the second pole component extending toward the second contact, wherein the second permanent magnet is rotatably disposed on the first pole component, and a third permanent magnet is rotatably disposed on the second pole component; a first electromagnet, disposed between the first permanent magnet and the second permanent magnet, and configured to generate magnetic force depending on whether an current is applied; and a second electromagnet, disposed between the first permanent magnet and the third permanent magnet, and configured to generate magnetic force depending on whether an current is applied.

[0017] The first and second contacts are made of a material such as steel that can magnetically attract permanent magnets. The pole unit further includes a partition wall disposed between the first and second pole components, and the partition wall is configured to separate the first pole component from the second pole component and the second permanent magnet from the third permanent magnet, respectively.

[0018] The first electromagnet is configured to form different polarities in the directions in which the first permanent magnet and the second permanent magnet face each other during the generation of magnetic force, and the second electromagnet is configured to form different polarities in the directions in which the first permanent magnet and the third permanent magnet face each other during the generation of magnetic force.

[0019] A guide extending toward the opening is disposed at the lower part of the vehicle body. The drive unit has a base plate disposed at the lower part of the closure component and is connected to the guide and configured to move along the guide.

[0020] The intelligent mobile unit also includes a controller, a drive unit, and a fixing unit. The controller is designed to control the drive unit and fixing unit to open the openings in the vehicle body based on whether a user is getting on or off the vehicle. The controller is configured to receive information about the user's direction of boarding or alighting by communicating with sensors mounted on the vehicle body or with the user; and during the user's boarding or alighting process, control the fixing unit of the extension frame located in the user's boarding or alighting direction among multiple extension frames to release the corresponding extension frame's fixation and control the drive unit to move away from the vehicle body.

[0021] The controller is configured to collect information about the vehicle's tilt angle, speed, or the presence of surrounding obstacles by communicating with external or vehicle-mounted sensors; and to ensure that the vehicle's openings remain closed if any of the following conditions are met: the vehicle's tilt angle is above a set angle; the vehicle's speed is above a set speed; and a surrounding obstacle is present.

[0022] The controller is configured to collect information about the vehicle's tilt or speed or the presence of surrounding obstacles by communicating with sensors located externally or on the vehicle body; and to determine the distance the drive unit moves away from the vehicle body based on each piece of information.

[0023] The controller is configured to: determine whether the vehicle body is located at a station during the separation process of the vehicle body and the drive unit; and when the vehicle body is identified as being located at a station, control all anchoring units to release their anchors and control the drive unit to detach from the vehicle body.

[0024] The separable and connectable intelligent mobile body with the above structure is configured to unfold or retract. When retracted, multiple frames overlap each other to ensure overall rigidity, while when unfolded, the openings of the vehicle body open to allow passengers to board, thus eliminating the need for separate doors and ensuring a wider entrance.

[0025] Furthermore, even when the mobile body is retracted, it is easy to manufacture because there are no doors for passengers to get on and off, and the size of the entrance is ensured even when the overall size of the mobile body is small, thereby improving user convenience.

[0026] The beneficial effects that can be obtained from this disclosure are not limited to those described above, and other effects not mentioned can be clearly understood by those skilled in the art from the following description. Attached Figure Description

[0054] In the following description, the embodiments described herein will be described in detail with reference to the accompanying drawings, and the same or similar elements are given the same and similar reference numerals regardless of the drawing numbers, so repeated descriptions will be omitted.

[0055] like Figures 1 to 4 As shown, the intelligent mobile body according to this disclosure includes: a vehicle body 100 having an interior space and openings 110 formed on one or both sides; a drive unit 200 including a closing member 210 and a drive module 220 mounted to the closing member 210, the closing member 210 being configured to mate with the openings 110 of the vehicle body 100, and the drive module 220 being configured to move the drive unit 200; a plurality of fixed frames 300 disposed on an inner or outer surface of the vehicle body 100 and extending in a longitudinal direction; a plurality of extension frames 400 detachably connected to the closing member 210, wherein each extension frame is connected to a corresponding fixed frame 300 and is configured to slide along the fixed frame 300; and a fixing unit 500 configured to allow the extension frames 400 to be selectively fixed when the extension frames 400 are positioned to contact the closing member 210.

[0056] The body 100 may include an outer panel b-1 and an inner panel b-2, each of which may have an external shape determined based on user requirements through a process such as roll forming. The outer panel b-1 and the inner panel b-2 of the body 100 may be assembled in a sliding manner.

[0057] The vehicle body 100 has an interior space, and openings 110 are provided on one or both sides, allowing communication between the interior and exterior through the openings 110. Here, the openings 110 can serve as entrances, and by making one or both sides of the vehicle body 100 open to form the openings 110, the manufacture of the vehicle body 100 can be made easier. Furthermore, since the size of the openings 110 is ensured to be proportional to the size of the vehicle body 100, the convenience of passengers getting on and off the vehicle through the openings 110 can be improved.

[0058] The drive unit 200 includes a closed component 210 and a drive module 220. The drive unit 200 can be configured to be a device that can determine its direction of movement and move independently, regardless of whether there is user operation. For example, the drive unit 200 can be an autonomous vehicle, an autonomous mobile robot, etc.

[0059] The drive unit 200 is designed such that the closing member 210 is aligned with the opening 110 of the vehicle body 100. When the drive unit 200 moves toward the opening 110, the closing member 210 closes the opening 110. The closing member 210 forms the front or rear of the moving body when connected to the opening 110 of the vehicle body 100. Furthermore, the external shape of the closing member 210 can be determined to match the design of the moving body, and the closing member 210 can include various convenient features, such as glass components.

[0060] A drive module 220 is provided at the lower part of the enclosed component 210, and the drive module 220 is a device for moving the vehicle body 100 and can be configured in various ways, such as electric wheels or a running gear. The drive module 220 may include components such as a motor or engine that provides power to the moving device and a steering device or steering wheel that adjusts the direction of the moving device.

[0061] Specifically, in this disclosure, the fixed frame 300 is disposed within the vehicle body 100, and the extension frame 400 is disposed within the enclosure 210 of the drive unit 200, and the extension frame 400 is slidably connected to the fixed frame 300. In other words, the fixed frame 300 extends longitudinally within the vehicle body 100, and the extension frame 400 is also configured to extend longitudinally along the fixed frame 300. Here, the term "longitudinal direction" refers to... Figure 1 The direction can be left or right, and can be the direction in which the opening 110 of the body 100 is formed or the opposite direction. For the connection structure in which the extension frame 400 slides along the fixed frame 300, various connection structures such as groove / protrusion structures can be applied.

[0062] The vehicle body 100 and the drive unit 200 can remain connected via the fixed frame 300 and the extension frame 400, and the drive unit 200 can be spaced apart from or separated from the vehicle body 100 depending on the movement position of the drive unit 200. Through this mechanism, when the drive unit 200 is separated from the vehicle body 100, the opening 110 of the vehicle body 100 is exposed, allowing passengers to get on and off; while when the drive unit 200 contacts the vehicle body 100, the opening 110 of the vehicle body 100 is closed, preventing the interior space from being exposed to the outside.

[0063] On the other hand, this disclosure includes a fixing unit 500, which is configured to fix or release the closure member 210 and the extension frame 400 of the drive unit 200. Multiple fixing units 500 can be provided to respectively mate with multiple extension frames 400. When the extension frame 400 and the closure member 210 are connected via the fixing unit 500, the extension frame 400 becomes exposed in a form extending from the vehicle body 100, depending on the movement position of the drive unit 200. When the connection between the extension frame 400 and the closure member 210 is released via the fixing unit 500, the extension frame 400 remains retracted into the vehicle body 100, thereby allowing passengers to get on and off the vehicle from the corresponding area.

[0064] The fixing unit 500 can be mounted to the enclosure 210 via a connector C provided in the enclosure 210 of the drive unit 200. The connector C is configured to provide space within the enclosure 210 for mounting the fixing unit 500 and can be applied in various forms depending on the shape of the enclosure 210.

[0065] Therefore, in this disclosure, when the drive unit 200 moves toward the vehicle body 100, the opening 110 of the vehicle body 100 closes. Conversely, when the drive unit 200 moves away, the opening 110 opens. In other words, with the closing member 210 of the drive unit 200 and the extension frame 400 fixed by the fixing unit 500, if the drive unit 200 moves away from the vehicle body 100, the extension frame 400 unfolds and extends from the vehicle body 100 while moving together with the drive unit 200. In this way, the vehicle body 100 and the drive unit 200 are connected by the extension frame 400, and at the location where the extension frame 400 is located, passenger boarding and alighting are blocked.

[0066] On the other hand, when the fixed unit 500 releases the fixed state between the closed part 210 of the drive unit 200 and the extension frame 400, the extension frame 400 remains inserted into the fixed frame 300 when the drive unit 200 is moved away from the vehicle body 100, and thus does not unfold from the vehicle body 100. Therefore, when the drive unit 200 is separated from the vehicle body 100, passengers can get on and off the vehicle by keeping the extension frame 400 in an unfolded position.

[0067] Specifically, in this disclosure, the vehicle body 100 includes an opening 110 on one side, and the vehicle body drive module A can be located on the side opposite to the opening 110. For example... Figure 1 As shown, the vehicle body 100 may include an opening 110 on only one side and be closed on the other side, and the vehicle body drive module A may be installed on the opposite side of the opening 110.

[0068] Therefore, the vehicle body 100 can move via the drive unit 200 and the vehicle body drive module A. The drive module 220 of the drive unit 200 and the vehicle body drive module A can be configured to have the same specifications and can communicate with each other, thereby controlling not only the direction of travel but also adjusting the distance between the drive unit 200 and the vehicle body 100. For example, when the drive unit 200 and the vehicle body drive module A are traveling at the same speed, the interior space of the vehicle body 100 remains closed, while when the drive unit 200 and the vehicle body drive module A are traveling away from each other, the drive unit 200 can be separated from the vehicle body 100.

[0069] The opening 110 provided on one side of the vehicle body 100 as described is merely an example. Openings 110 may be provided on both sides of the vehicle body 100, and the drive unit 200 corresponds to each opening 110.

[0070] On the other hand, multiple fixed frames 300 are spaced apart from each other along the inner periphery of the vehicle body 100 and are provided with longitudinally elongated hollow portions. The number of extension frames 400 can correspond to the number of fixed frames 300, and the extension frames 400 can extend longitudinally to be inserted into the hollow holes respectively.

[0071] like Figure 1 and Figure 5 As shown, multiple fixed frames 300 are spaced apart from each other along the inner periphery of the vehicle body 100, and multiple extended frames 400 are similarly spaced apart from each other along the periphery of the enclosure 210 of the drive unit 200 at the same intervals as the fixed frames 300. Therefore, when the vehicle body 100 and the drive unit 200 are connected by the fixed frames 300 and the extended frames 400, the structural connection rigidity and balance are ensured.

[0072] Furthermore, since the multiple fixed frames 300 and extension frames 400 are spaced apart, the number and position of the extension frames 400 extending from the fixed frames 300 can be varied, thereby changing the accessible entry point from the outside to the opening 110. On the other hand, the fixed frames 300 extend longitudinally and have a hollow portion, while the extension frames 400 also extend longitudinally and are inserted into the inside of the fixed frames 300, allowing the extension frames 400 to slide and move linearly within the fixed frames 300.

[0073] Therefore, when the extension frame 400 is fixed to the drive unit 200 by the fixing unit 500, the extension frame 400 can move within the fixing frame 300 according to the moving position of the drive unit 200, and the extension frame 400 can be extended from the vehicle body 100 or retracted into the fixing frame 300 according to the position of the drive unit 200.

[0074] On the other hand, each extension frame 400 may include a slider 410 connected to the fixed frame 300, enabling the extension frame to reciprocate linearly along the fixed frame 300, and the slider 410 may be equipped with a sliding or rolling function.

[0075] For example, such as Figure 6 As shown, the slider 410 can be constructed as a ball bearing with internal balls, and when the slider 410 is connected to the fixed frame 300, the extension frame 400 can move smoothly within the fixed frame 300 while the multiple balls perform rolling actions.

[0076] In addition to the rolling function, the slider 410 can also be configured to slide using a low-friction structure. In this way, the extension frame 400 can be connected to the fixed frame 300 via the slider 410, and the extension frame 400 can slide within the fixed frame 300 when the slider 410 moves in a sliding or rolling manner within the fixed frame 300.

[0077] On the other hand, the length of the extension frame 400 can be the same as or longer than the length of the fixed frame 300, so that when the extension frame 400 is inserted into the hollow hole of the fixed frame 300, one end can be partially exposed from the fixed frame 300.

[0078] Reference Figure 4 The extension frame 400 extends outward from the vehicle body 100 when it slides out of the fixed frame 300, or retracts to be accommodated overlapping within the fixed frame 300. Here, when the drive unit 200 is positioned to contact the vehicle body 100, the extension frame 400 should be fixed to the drive unit 200 via the fixed unit 500. Therefore, even when accommodated overlapping within the fixed frame 300, the extension frame 400 remains partially exposed outside the vehicle body 100, thereby allowing interconnection between the fixed unit 500 and the extension frame 400 when the drive unit 200 is positioned to contact the vehicle body 100.

[0079] On the other hand, the fixed frame 300 may include: a main support portion 310 having a hollow hole, extending longitudinally and fixed to the vehicle body 100; and a secondary support portion 320 extending circumferentially from the main support portion 310 and fixed to the vehicle body 100.

[0080] In this configuration, the fixed frame 300 may include a main support portion 310 and a secondary support portion 320, wherein the secondary support portion 320 extends circumferentially from opposite sides of the main support portion 310. The main support portion 310 may also be thicker than the secondary support portion 320. Therefore, the fixed frame 300 is supported by the secondary support portions 320 extending from both sides of the main support portion 310, thereby preventing the fixed frame 300 from tilting relative to the vehicle body 100. In addition, the main support portion 310 and the secondary support portion 320 are firmly connected to the vehicle body 100, thereby providing structural stability and achieving a stable support structure even when the extension frame 400 is inserted into the hollow hole of the fixed frame 300.

[0081] On the other hand, the fixing unit 500 according to this disclosure can be applied in various embodiments.

[0082] In an embodiment, such as Figures 7 to 9 As shown, the fixing unit 500 may include a fixing component 510 and a connecting component 520.

[0083] Here, the fixing member 510 can be disposed on one of the closing member 210 and the extension frame 400, while the connecting member 520 can be disposed on the other of the closing member 210 and the extension frame 400. In this disclosure, it is assumed that the fixing member 510 is disposed on the extension frame 400, and the connecting member 520 is disposed on the closing member 210 of the drive member 200, but the mounting positions of the fixing member 510 and the connecting member 520 can be configured to be opposite to each other. However, since the connecting member 520 requires current to operate the electromagnet 524, the connecting member 520 can be mounted on the drive unit 200.

[0084] The fixing member 510 may be made of a magnetically pleasing material including steel. The fixing member 510 may be provided at the end of each extension frame 400.

[0085] The connecting component 520 includes: a pole component 521 made of a magnetically attractive material; a first magnet 522 rotatably disposed on the pole component 521; a second magnet 523 fixed to the pole component 521 at a certain distance from the first magnet 522; and an electromagnet 524 that generates magnetic force when an electric current is applied.

[0086] The pole member 521 has a pair of ends in its cross-section, and generates magnetic flux at each end, enabling the ends to be magnetically connected to corresponding components. For example, the pole member 521 may have a cylindrical or polygonal shape with an internal space, and a first magnet 522 and a second magnet 523 may be disposed within the internal space. Magnetic flux can be generated in the pole member 521 by the first magnet 522 and the second magnet 523, and the direction of the magnetic flux can be determined based on the rotational position of the first magnet 522.

[0087] The first magnet 522 and the second magnet 523 can be permanent magnets. Therefore, when the fixed member 510 and the pole member 521 come into contact with each other, a magnetic flux is generated. The magnetic flux passes from the pole member 521 through the fixed member 510, so that the fixed member 510 and the pole member 521 are magnetically connected to each other.

[0088] On the other hand, the first magnet 522 is configured to be rotatable in the pole member 521, and the electromagnet 524 is disposed between the first magnet 522 and the second magnet 523 in the pole member 521 to adjust the rotational position of the first magnet 522 by generating magnetic force.

[0089] That is, when an electric current is applied to the electromagnet 524, it acquires polarity, and the first magnet 522 responds to the polarity of the electromagnet 524, thereby changing the rotational position of the first magnet 522 through attractive and repulsive forces. As the first magnet 522 rotates, the magnetic flux between the first magnet 522 and the second magnet 523 can change, and through this change in magnetic flux, the pole member 521 can be selectively fixed to the fixing member 510.

[0090] When the electromagnet 524 generates magnetic force, opposite polarities are formed in the directions where the first magnet 522 and the second magnet 523 face each other. For example, the electromagnet 524 may have an S pole facing the first magnet 522 and an N pole facing the second magnet 523. Specifically, the directions of the N and S poles of the first magnet 522 switch according to the rotational position of the first magnet 522. Since the second magnet 523 is fixed to the pole member 521, the positions of the N and S poles of the second magnet 523 are fixed.

[0091] Here, as Figure 7 As shown, when the polarities of the first magnet 522 and the second magnet 523 are arranged to cross, a magnetic current is formed that passes through the first magnet 522 and the second magnet 523. That is, since the magnetic current is formed only within the pole member 521, the pole member 521 may be in an unengaged state even when it is in contact with the fixing member 510.

[0092] Here, as Figure 8 As shown, when an electric current is applied to the electromagnet 524 and a magnetic force is generated, the first magnet 522 rotates due to the magnetic force of the electromagnet 524. For example, when the S pole and N pole of the second magnet 523 are located at the top and bottom respectively, and the electromagnet 524 is positioned with its S pole facing the first magnet 522 and its N pole facing the second magnet 523, the first magnet 522 rotates in response to the attractive and repulsive forces of the S pole of the electromagnet 524.

[0093] Therefore, as Figure 9 As shown, as the first magnet 522 rotates and the polarities of the first magnet 522 and the second magnet 523 match, a magnetic flux is generated in the pole member 521. Since the magnetic field is formed in the direction passing through the pole member 521 and the fixed member 510 engaged with the pole member 521, the pole member 521 and the fixed member 510 are engaged in a consistent state.

[0094] At this time, even if no current is applied to the electromagnet 524 and no polarity is generated, the engagement state of the fixing member 510 and the pole member 521 can be maintained due to the polarity matching of the first magnet 522 and the second magnet 523.

[0095] By causing the electromagnet 524 to have a polarity opposite to that formed when the fixing member 510 and the pole member 521 are engaged, the engagement state obtained by the fixing unit 500 according to the embodiment can be released. That is, by rotating the first magnet 522 by the electromagnet 524, causing the polarities of the first magnet 522 and the second magnet 523 to cross, the engagement state between the pole member 521 and the fixing member 510 can be released.

[0096] on the other hand, Figure 10 This is another embodiment of the fixed unit 500.

[0097] Here, the fixing unit 500 includes a first contact 530 and a second contact 540 respectively disposed on the closing member 210 and the extension frame 400.

[0098] The first contact 530 is disposed on the closed member 210, the second contact 540 is disposed on the extension frame 400, and each contact may be made of a material including steel that can magnetically attract each permanent magnet.

[0099] The first contact 530 and the second contact 540 can be integrally constructed with the closure member 210 and the extension frame 400, respectively, or they can be manufactured separately and then combined with the closure member 210 and the extension frame 400.

[0100] On the other hand, the fixing unit 500 includes a pole unit 550 that is engaged with the first contact 530 and the second contact 540.

[0101] The pole unit 550 includes a first pole component 551 and a second pole component 552, and the first pole component 551 and the second pole component 552 are spaced apart from each other. The first pole component 551 is configured to contact a first contact 530, and the second pole component 552 is configured to contact a second contact 540.

[0102] Here, the pole unit 550 may further include a partition wall 580 located between the first pole component 551 and the second pole component 552.

[0103] like Figure 11 As shown, the partition wall 580 can be configured to separate the first pole member 551 from the second pole member 552, the second permanent magnet 554 from the third permanent magnet 555, and the first electromagnet 560 from the second electromagnet 570. The partition wall 580 can be made of a material unaffected by magnetic forces. The partition wall 580 minimizes the change in magnetic flux caused by interference between the magnetic fields in each pole member 551 or 552, each permanent magnet 554 or 555, and each electromagnet 560 or 570. Furthermore, since the magnetic flux through each pole member 551 or 552 is generated only along a predetermined path by the partition wall 580, the magnetic flux can be designed without increasing the size of the first permanent magnet 553.

[0104] A first permanent magnet 553 is configured to contact the first pole member 551 and the second pole member 552, and in this disclosure, it is assumed that a first permanent magnet 553 is connected to both the first pole member 551 and the second pole member 552. The first permanent magnet 553 may be disposed in each of the first pole member 551 and the second pole member 552.

[0105] On the other hand, the second permanent magnet 554 is rotatably disposed in the first pole component 551, the third permanent magnet 555 is rotatably disposed in the second pole component 552, the first electromagnet 560 is located between the first permanent magnet 553 and the second permanent magnet 554, and the second electromagnet 570 is disposed between the first permanent magnet 553 and the third permanent magnet 555.

[0106] Thus, when a current is applied to the first electromagnet 560 to generate a magnetic force, the second permanent magnet 554 can rotate by the magnetic force of the first electromagnet 560, and when a current is applied to the second electromagnet 570 to generate a magnetic force, the third permanent magnet 555 can rotate by the magnetic force of the second electromagnet 570.

[0107] That is, when the second permanent magnet 554 rotates due to the polarity change of the first electromagnet 560, the magnetic flux between the first permanent magnet 553 and the second permanent magnet 554 can change, and when the third permanent magnet 555 rotates due to the polarity change of the second electromagnet 570, the magnetic flux between the first permanent magnet 553 and the third permanent magnet 555 can change. Therefore, magnetic forces are generated in the first pole member 551 and the second pole member 552 by the first electromagnet 560 and the second electromagnet 570, respectively. The first pole member 551 can be selectively engaged with the first contact member 530, and the second pole member 552 can be selectively engaged with the second contact member 540.

[0108] During the generation of magnetic force, the first electromagnet 560 of this disclosure forms different polarities in the directions in which the first permanent magnet 553 and the second permanent magnet 554 face each other, and similarly, the second electromagnet 570 forms opposite polarities in the directions in which the first permanent magnet 553 and the third permanent magnet 555 face each other.

[0109] Specifically, the first permanent magnet 553 is fixed at an appropriate position in the first pole component 551 and the second pole component 552, and the orientation of the N pole and the S pole in each of the pole components 551 and 552 is switched according to the rotational position of the second permanent magnet 554 and the third permanent magnet 555.

[0110] Based on this, the connection relationship between the first contact 530 and the first pole component 551 will be explained. For example... Figure 10 As shown, relative to the first permanent magnet 553, when each of the polarities of the first permanent magnet 553 is arranged to intersect with each of the polarities of the second permanent magnet 554 and the third permanent magnet 555, magnetic flux is generated between the first permanent magnet 553 and the second permanent magnet 554, and between the first permanent magnet 553 and the third permanent magnet 555. Therefore, the first pole member 551 and the second pole member 552 are not engaged with the first contact member 530 and the second contact member 540, respectively.

[0111] Here, as Figure 12As shown, when an electric current is applied to the first electromagnet 560 and a magnetic force is generated, the second permanent magnet 554 rotates in response to the magnetic force of the first electromagnet 560. For example, when the S pole and N pole of the first permanent magnet 553 are located at the top and bottom respectively, the first electromagnet 560 establishes an N pole facing the first permanent magnet 553 and an S pole facing the second permanent magnet 554, and the second permanent magnet 554 rotates in response to the attractive and repulsive forces of the S pole of the first electromagnet 560.

[0112] Therefore, as Figure 13 As shown, as the second permanent magnet 554 rotates and the polarities of the second permanent magnet 554 and the first permanent magnet 553 are matched, a magnetic current is generated in the first pole member 551, and since the magnetic field is formed in the direction passing through the first pole member 551 and the first contact member 530, the first pole member 551 and the first contact member 530 can engage.

[0113] At this time, even when no current is applied to the first electromagnet 560 and therefore no polarity is established, the engagement state of the first contact 530 and the first pole member 551 can be maintained due to the polarity matching of the first permanent magnet 553 and the second permanent magnet 554.

[0114] Regarding the connection relationship between the second contact 540 and the second pole component 552, as follows: Figure 14 As shown, when an electric current is applied to the second electromagnet 570, thereby generating a magnetic force, the third permanent magnet 555 rotates in response to the magnetic force of the second electromagnet 570. For example, when the S pole and N pole of the first permanent magnet 553 are respectively positioned at the top and bottom, the second electromagnet 570 establishes an N pole facing the first permanent magnet 553 and an S pole facing the third permanent magnet 555, and the third permanent magnet 555 rotates in response to the attractive and repulsive forces of the S pole of the second electromagnet 570.

[0115] Therefore, as Figure 15 As shown, as the third permanent magnet 555 rotates and the polarities of the third permanent magnet 555 and the first permanent magnet 553 are matched, a magnetic current is generated in the second pole member 552, and since the magnetic field is formed in the direction passing through the second pole member 552 and the second contact member 540, the second pole member 552 and the second contact member 540 can engage.

[0116] As described above, the fixing unit 500 of this disclosure can be constructed according to various embodiments based on a unidirectional magnetic flux fixing structure and a bidirectional magnetic flux fixing structure.

[0117] On the other hand, such as Figure 16 and Figure 17As shown, the vehicle body 100 has a guide 120 extending toward the opening 110 at the bottom, and the drive unit 200 includes a base plate 230 at the lower part of the closed component 210, and the base plate 230 is connected to the guide 120 to move along the guide 120.

[0118] The guide 120 can be located at the lower part of the vehicle body 100 and is configured as a track extending toward the opening 110. The drive unit 200 has a base plate 230 at the lower part of the enclosure 210, and the base plate 230 is connected to the guide 120 of the vehicle body 100 and configured to move along the guide 120. Therefore, the base plate 230 and the guide 120 can be connected to each other using a track connection structure. In addition, the base plate 230 can be stably connected to the guide 120 by applying a reinforcing structure to support the load including passengers. The reinforcing structure can be applied in various forms, including bearing structures.

[0119] On the other hand, various convenience features, including seats, can be provided on the floor 230. That is, the floor 230 serves as a space where passengers can stay when the drive unit 200 is connected to the vehicle body 100, and various convenience features, including seats, can be provided on the side of the drive unit 200. As a result, when the drive unit 200 is separated from the vehicle body 100 to allow passengers to get on and off, passengers on the floor 230 of the drive unit 200 can move off the vehicle body 100 together with the drive unit 200, or when boarding the floor 230, passengers can enter the vehicle body 100 together with the drive unit 200.

[0120] For user convenience, the controller 600 can be used to control the detachable and connectable intelligent mobile body described in this disclosure. The controller 600 is configured to control the drive unit 200 and the fixing unit 500, and according to the user getting on or off the vehicle, the controller 600 controls the drive unit 200 and the fixing unit 500 to open the opening 110 of the vehicle body 100.

[0121] That is, the controller 600 determines whether the drive unit 200 is fixed to the vehicle body 100 by controlling the movement position of the drive unit 200 and the fixing unit 500. Then, the controller 600 opens or closes the opening 110 of the vehicle body 100.

[0122] Specifically, the controller 600 receives information based on the user's direction of getting on or off the vehicle through communication with the user or the sensor S installed in the vehicle body 100.

[0123] Sensor S can be a camera, lidar, laser, etc., that detects the interior or exterior of the vehicle body 100, and can identify the user's location by communicating with the user's terminal.

[0124] Therefore, when a user wants to board or disembark from the mobile vehicle, the controller 600 controls the fixing unit 500 to release the fixing of the multiple extension frames 400 located in the direction of passenger boarding or disembarking, and controls the drive unit 200 to move away from the vehicle body 100.

[0125] That is, such as Figure 18 and Figure 19 As shown, among the multiple extension frames 400 connecting the vehicle body 100 and the drive unit 200, when the extension frame 400 matching the direction of the passenger is released from the fixed position by the fixed unit 500, even if the drive unit 200 is moved away from the vehicle body 100, the corresponding extension frame 400 does not extend from the vehicle body 100, and only the remaining extension frame 400 unfolds.

[0126] In this way, since the extension frame 400 matching the direction of the passenger does not deploy from the vehicle body 100, the passenger can get on and off in the corresponding area, and the remaining extension frame 400 connects between the vehicle body 100 and the drive unit 200 to form a support structure and thus support the load. Additionally, for pre-identified users, all extension frames 400 except those aligned with the user's position are deployed. This prevents other users from getting on in the area where the extension frames 400 are deployed and extended. On the other hand, the controller 600 can collect information about the tilt or speed of the vehicle body 100 or the presence of surrounding obstacles through sensors S installed in the vehicle body 100 or through external communication.

[0127] Here, sensor S can include any one of tilt sensor, camera, lidar, laser, gravity sensor, and velocity sensor, and can receive information about the area where the moving body is currently located based on GPS information. In this disclosure, sensor S is a general term for various sensors and can be used to collect various information, including the detection of internal and external objects, velocity, position, and tilt.

[0128] In this way, the controller 600 receives information about the tilt and speed of the vehicle body 100 and the presence or absence of surrounding obstacles through various sensors S, and keeps the opening 110 of the vehicle body 100 closed if any of the following conditions are met: the tilt of the vehicle body 100 is above a set angle; the speed of the vehicle is above a set speed; and there are surrounding obstacles.

[0129] For example, the set angle can correspond to a ground slope of 5° or greater, and the set speed can be a driving speed of 1 km / h or greater. As mentioned earlier, the controller 600 ensures that the drive unit 200 remains connected to the vehicle body 100 because if the tilt of the vehicle body 100 exceeds the set angle, precise position control of the drive unit 200 may become impossible, or passenger boarding and alighting may become unsafe. Additionally, when the vehicle body 100's driving speed exceeds the set speed, the controller 600 determines that the vehicle is moving and ensures that the drive unit 200 remains connected to the vehicle body 100.

[0130] Furthermore, when there are obstacles around the moving body, the drive unit 200 may interfere with the obstacles or passengers during movement. Therefore, the controller 600 ensures that the drive unit 200 remains connected to the vehicle body 100 during movement.

[0131] Therefore, by evaluating information under various conditions and controlling the drive unit 200 and the fixing unit 500, the controller 600 determines whether the opening 110 should be opened or closed, thereby preventing potential safety accidents.

[0132] In addition, based on each of the above information items, the controller 600 can calculate the distance that the drive unit 200 moves away from the vehicle body 100.

[0133] For example, when there are obstacles around the moving body, the drive unit 200 can move only to a degree that does not interfere with the obstacles, thereby allowing the opening 110 of the vehicle body 100 to open. When passenger movement is restricted, the drive unit 200 can move to its maximum position to ensure sufficient space for passengers to get on and off.

[0134] On the other hand, such as Figure 20 As shown, when separation between the vehicle body 100 and the drive unit 200 is detected, the controller 600 identifies whether the vehicle body 100 is located at station P. If the vehicle body 100 is identified as being at station P, the controller 600 can control all fixing units 500 to release their fixings and control the drive unit 200 to detach from the vehicle body 100.

[0135] Station P is equipped with facilities for charging or maintaining the battery in vehicle body 100. Station P may also include equipment to support the vehicle body 100 of the moving body. Therefore, controller 600 only allows vehicle body 100 to separate from drive unit 200 when vehicle body 100 is located at station P during the time when vehicle body 100 is separated from drive unit 200, thereby preventing vehicle body 100 from losing balance due to center of gravity shift when drive unit 200 is separated from vehicle body 100.

[0136] Therefore, when the vehicle body 100 separates from the drive unit 200, the controller 600 releases all fixing units 500 to allow the drive unit 200 to detach from the vehicle body 100 and to allow the drive unit 200 to be completely removed from the vehicle body 100. Alternatively, the controller 600 can, based on the state of the vehicle body 100 and the drive unit 200 at station P, control the drive unit 200 to be completely removed from the vehicle body 100 while all fixing units 500 remain fixed.

[0137] The intelligent mobile body, having the detachable and connectable structure described above, is configured to unfold or retract. When retracted, multiple frames overlap each other to ensure overall rigidity, while when unfolded, the opening 110 of the body 100 opens to allow passengers to board, thus eliminating the need for separate doors and ensuring a wider entrance passage.

[0138] Furthermore, even when the mobile body is retracted, it is easy to manufacture because there are no doors for passengers to get on and off, and the size of the entrance is ensured even when the overall size of the mobile body is small, thereby improving user convenience.

[0139] Although the present disclosure has been described and illustrated with reference to specific embodiments, it will be apparent to those skilled in the art that various improvements and modifications can be made without departing from the technical scope of the present disclosure as defined by the appended claims.
