[0029] Figure 10 and Figure 11 A modified example of a control method for a personal mobile device according to an embodiment of the present disclosure is shown. Detailed Implementation

[0030] Embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. The embodiments described below are provided by way of example so that those skilled in the art will be able to fully understand the spirit of this disclosure. This disclosure is not limited to the embodiments described below, but may be embodied in other forms. For clarity of explanation, parts unrelated to the description have been omitted from the drawings, and for convenience, the width, length, thickness, etc., of components may be exaggerated.

[0031] refer to Figure 1 and Figure 2 A personal mobility device according to an embodiment of the present disclosure may include: a front body 10, on which front wheels 11 and a steering wheel 12 are mounted; a rear body 20, which is slidably coupled to the rear end of the front body 10 and on which rear wheels 21 are mounted; a sliding connection unit 30 for connecting the front body 10 and the rear body 20; a drive unit, which may be a telescopic drive unit 50, for moving the rear body 20 forward and backward to adjust the wheelbase; and a locking device 60 for locking or releasing the sliding connection unit 30.

[0032] At least one of the front wheel 11 and the rear wheel 12 may be provided with a wheel drive motor 11a or 21a for driving, and a battery (not shown) that provides power to the wheel drive motor 11a or 21a may be installed on at least one of the front body 10 and the rear body 20.

[0033] In the personal mobility device of this embodiment, since the front body 10 and the rear body 20 are connected by a sliding connection unit 30, the rear body 20 can move forward and backward to adjust the wheelbase. For example, when one person is riding, the wheelbase can be adjusted to be relatively shorter by moving the rear body 20 forward, while when two people are riding, the wheelbase can be adjusted to be relatively longer by moving the rear body 20 backward.

[0034] refer to Figure 2 and Figure 3 The sliding connection unit 30 may include: an upper support rail 31, which is respectively disposed on the opposite upper side of the front vehicle body 10 and extends in the front-rear direction; an upper extension portion 32, which extends forward from the upper side of the rear vehicle body 20 and is slidably coupled to the upper support rail 31 located on its opposite side; a lower support rail 33, which is respectively disposed on the opposite lower side of the front vehicle body 10 and extends in the front-rear direction; and a lower extension portion 34, which extends forward from the lower side of the rear vehicle body 20 and is slidably coupled to the lower support rail 33 located on its opposite side.

[0035] The upper extension 32 may be flat and include a rail 32a disposed on the opposite side to couple with and correspond to the upper support rail 31. The lower extension 34 may be disposed in a lower portion spaced apart from the upper extension 32 in the same form as the upper extension 32. Buffer blocks 31a and 33a for limiting the entry of the upper extension 32 and the lower extension 34 and buffering the impact caused by the entry may be installed at the front ends of the upper support rail 31 and the lower support rail 33 inside the front vehicle body 10.

[0036] A seat 70 for multiple users may be provided on the upper portion of the upper extension 32, and a cargo space 80 may be provided between the upper extension 32 and the lower extension 34. The seat 70 may extend relatively far in the fore-and-aft direction to cover the upper surface of the upper extension 32.

[0037] The front end of the seat 70 can enter the interior of the front body 10 together with the upper extension 32. Therefore, the exposed length of the seat 70 can be lengthened or shortened according to the wheelbase adjustment. The rear body 20 may include a backrest portion 23 that extends upwards beyond the height of the seat 70.

[0038] Cargo 81 can be loaded in the cargo space 80 above the lower extension 34. When the amount of cargo 81 is large, the cargo space 80 can be increased by adjusting the wheelbase to be longer, and when the amount of cargo 81 is small, the cargo space 80 can be reduced by adjusting the wheelbase to be shorter.

[0039] The telescopic drive unit 50 may include: a rack 51 mounted on the lower surface of the upper extension 32 to extend elongatedly in the longitudinal direction of the upper extension 32; a pinion 52 located inside the front body 10 and engaging with the rack 51; and a drive motor 53 fixed to the inside of the front body 10 to rotate the pinion 52 in the forward and reverse directions.

[0040] The telescopic drive unit 50 can rotate the pinion 52 by operating the drive motor 53 to move the rack 51 in the front-rear direction. Therefore, the rear body 20 can move forward or backward to lengthen or shorten the wheelbase.

[0041] The drive motor 53 of the telescopic drive unit 50 can be an encoder motor, a stepper motor, a servo motor, etc., which can achieve precise movement of the rear vehicle body 20 through precise rotation angle control. The drive motor 53 may include a reduction gear to rotate the pinion 52 with a large force.

[0042] refer to Figure 2 , Figure 4 and Figure 5 The locking device 60 may include a plurality of locking holes 61 disposed on the track 32a of the upper extension 32 and arranged to be spaced apart from each other in the longitudinal direction of the upper extension 32; a locking pin 62 capable of locking the upper extension 32 by entering one of the plurality of locking holes 61; and an actuator 63 mounted on the upper support track 31 to advance or retract the locking pin 62 in the locking or unlocking direction.

[0043] The locking device 60 can lock the sliding connection unit 30 by raising the locking pin 62 so that the locking pin 62 enters the locking hole 61, such as... Figure 4 As shown, the locking of the sliding connection unit 30 can be released by lowering the locking pin 62 to separate the locking pin 62 from the locking hole 61, as... Figure 5 As shown.

[0044] The locking device 60 can release the lock of the sliding connection unit 30 when the telescopic drive unit 50 is operated to adjust the wheelbase, and can lock the sliding connection unit 30 when the telescopic drive unit 50 stops operating after adjusting the wheelbase. The operation of the telescopic drive unit 50 can be controlled by a program that is set so that during the adjustment of the wheelbase, one of the locking holes 61 can be accurately stopped at the position of the locking pin 62.

[0045] refer to Figure 8 The personal mobile device in this embodiment may include a wireless communication module 91, an operator 92, multiple user access sensors 93, a riding sensor 94, a load sensor 95, an alarm 96, and a controller 90.

[0046] The wireless communication module 91 can communicate with the control server 100 via a wireless network. The wireless communication module 91 can send information from the control server 100 to the controller 90, or send information from the controller 90 to the control server 100.

[0047] Users who wish to rent and use a personal mobile device can request user authentication from the control server 100 through the user terminal 110. Taking into account membership information, payment information, etc., the control server 100 can send information about whether authentication is required to the controller 90 of the corresponding personal mobile device.

[0048] Users can pre-enter and send information about the number of passengers into the user terminal 110, and the controller 90 of the personal mobility device can control the operation of the telescopic drive unit 50 and the locking device 60 to adjust the wheelbase based on the sent information about the number of passengers. The user terminal 110 can be a smartphone with a service application (APP) or various portable terminals capable of wireless communication.

[0049] The operator 92 can be mounted on the steering wheel 12, etc., and can send information input by the user to the controller 90. The user can operate the operator 91 to control the overall operation of the personal mobility device. Therefore, the user can directly input information related to wheelbase adjustment and information related to the driving of the personal mobility device through the operator 92.

[0050] Multiple user access sensors 93 can be mounted on the front body 10 and the rear body 20 and can detect the number of users accessing the personal mobility device. The user access sensors 93 can be configured as ultrasonic sensors. The controller 90 can identify the number of users based on the detection of the multiple user access sensors 93 and can control the operation of the telescopic drive unit 50 and the locking device 60 to adjust the wheelbase to lengthen or shorten based on the number of users.

[0051] like Figure 1 and Figure 3 As shown, a occupancy sensor 94 can be mounted on the upper backrest portion 23 of the rear vehicle body 20. The occupancy sensor 94 can detect whether a user is sitting and the distance 94 between the passenger's back and the occupancy sensor. The occupancy sensor 94 can be configured as a laser sensor.

[0052] The controller 90 can determine whether a user has boarded the vehicle based on the detection of the occupancy sensor 94, and can determine whether the wheelbase has been properly adjusted based on the distance between the passenger's back and the backrest 23. When the distance between the passenger's back and the backrest 23 exceeds a set range, the controller 90 can control the operation of the telescopic drive unit 50 and the locking device 60 to readjust the wheelbase.

[0053] A load sensor 95 may be installed on the rear side of the vehicle body 20. The load sensor 95 can detect the weight of passengers and cargo 81 loaded in the cargo compartment 80. The controller 90 can determine whether the weight of cargo 81 and passengers is appropriate based on the detection of the load sensor 95 after the user has boarded, and can control the system to issue an overload warning via alarm 96 when it is determined that the load exceeds the set load or is inappropriate.

[0054] In the following text, reference will be made to Figure 9 The flowchart describes a method for controlling a personal mobile device according to embodiments of the present disclosure.

[0055] When the use of the personal mobile device is authenticated, the controller 90 identifies the number of users in step 121 based on the detection information of multiple user access sensors 93 or the information input by the user through the user terminal 110, and determines in step 122 whether the number of users exceeds the initial setting.

[0056] When it is determined in step 122 that the number of users has exceeded the initial setting, the controller 90 controls the telescopic drive unit 50 to extend the wheelbase in step 123. When it is determined in step 122 that the number of users has not exceeded the initial setting, the controller 90 controls the telescopic drive unit 50 in step 124 to maintain the wheelbase at the initial state. When the telescopic drive unit 50 is operating, the controller 90 controls the release locking device 60.

[0057] The initial number of users can be one, and as follows: Figure 6 As shown, the initial state of the wheelbase can be achieved by adjusting the wheelbase to a first distance L1, allowing one person to sit comfortably. Therefore, when the vehicle is parked, the wheelbase can be maintained in its initial state, as shown below. Figure 6 As shown. When it is determined that two users are approaching a personal mobile device at the same time as the initial number of users is one, as... Figure 7 As shown, controller 90 adjusts the wheelbase to a second distance L2 to accommodate two people. The initial setting for the number of users can be changed to two or more, and the initial setting for the wheelbase can also be changed accordingly.

[0058] The controller 90 controls the wheelbase adjustment to correspond to the number of users, then controls the ride sensor 94 in step 125 to detect the users' ride, and in step 126 determines whether the users have already ridden based on the detection information from the ride sensor 94.

[0059] When it is determined in step 126 that the user has already boarded the vehicle, the controller 90 determines in step 127 whether the adjusted wheelbase is appropriate by calculating the distance between the passenger's back and the seating sensor 94. Whether the wheelbase is appropriate can be determined by comparing the distance with preset information. If it is determined in step 127 that the wheelbase is inappropriate, in step 128, the controller 90 controls the telescopic drive unit 50 to be operated to readjust the wheelbase.

[0060] After the user boards, the controller 90 controls the load sensor 95 in step 129 to detect the weight of the cargo 81 and the passenger, and determines in step 130 whether the measured load is appropriate. If it is determined in step 130 that the load is inappropriate (the load exceeds the set value), the controller 90 controls the alarm 96 to issue an overload warning in step 131. When it is determined in step 130 that the load is appropriate, the personal mobility device is switched to a drivable state.

[0061] After step 130, the controller 90 determines in step 132 whether the personal mobility device has started moving and in step 133 controls the locking device 60 to lock the sliding connection unit 30 when moving begins. This is to prevent the wheelbase from changing during movement.

[0062] After step 133, the controller 90 determines in step 134 whether the driving has been completed and in step 135 controls the operation of the telescopic drive unit 50 and the locking device 60 to initialize the wheelbase when the driving is completed.

[0063] As described above, the personal mobility device according to this embodiment can easily adjust its wheelbase in response to changes in the number of passengers or the amount of cargo, because the front vehicle body 10 and the rear vehicle body 20 can be slidably connected and the wheelbase can be changed by the operation of the telescopic drive unit 50 and the locking device 60. That is, the length of the seat 70 can be changed in response to the number of passengers, or the volume of the cargo space 80 can be changed in response to the amount of cargo 81.

[0064] Furthermore, the personal mobile device according to this embodiment can be conveniently used because the wheelbase can be automatically adjusted based on the detection of the user access sensor 93 or information input by the user.

[0065] Figure 10 A modified example of a control method for a personal mobile device according to an embodiment of the present disclosure is shown.

[0066] exist Figure 10 In the control method, when the use of the personal mobility device is authenticated, in step 120a, the controller 90 determines whether the device's power is on. When it is determined in step 120a that the power is on, the controller 90 controls the telescopic drive unit 50 in step 121a to adjust the wheelbase to a single-person seating condition. In this case, as... Figure 6As shown, the wheelbase can be adjusted to the first distance L1, allowing one person to ride comfortably.

[0067] After the wheelbase is adjusted to a single-occupancy condition, in step 122a, the controller 90 determines whether a manual adjustment signal for wheelbase adjustment is generated due to the user's operation of the operator 92. This is to allow the user to directly operate the operator 92 to adjust the wheelbase to a condition where two or more people can sit, if necessary, while the wheelbase is adjusted to a single-occupancy condition.

[0068] When a manual adjustment signal is determined to have been generated in step 122a, the controller 90 controls the telescopic drive unit in step 123a to readjust the wheelbase in response to the manual adjustment signal. When no manual adjustment signal is determined to have been generated in step 122a, the controller 90 maintains the original wheelbase in step 124a.

[0069] After adjusting the wheelbase, the controller 90 controls the occupancy sensor 94 in step 125 to detect the user's occupancy, and in step 126 determines whether the user has already occupied the vehicle based on the detection information from the occupancy sensor 94.

[0070] When it is determined in step 126 that the user has already boarded the vehicle, the controller 90 determines in step 127 whether the adjusted wheelbase is appropriate by calculating the distance between the passenger's back and the seating sensor 94. Whether the wheelbase is appropriate can be determined by comparing the distance with preset information. If it is determined in step 127 that the wheelbase is inappropriate, the controller 90 controls the telescopic drive unit 50 to be operated in step 128 to readjust the wheelbase.

[0071] Figure 10 The control method in steps 129 to 135 of the example can be compared with Figure 9 The examples are basically the same.

[0072] Figure 11 Another modified example of a control method for a personal mobile device according to an embodiment of the present disclosure is shown.

[0073] exist Figure 11 In the control method, when the use of the personal mobile device is authenticated, the controller 90 determines in step 121b whether the device is powered on. When it is determined in step 121b that the power is on, the controller 90 determines in step 122b whether one or more user access sensors have detected one or more users. When it is determined in step 122b that one or more users have been detected, the controller 90 controls the telescopic drive unit 50 to extend the wheelbase to its maximum in step 123b.

[0074] After the wheelbase is adjusted to its maximum, the controller 90 controls the occupancy sensor 94 to detect the user's occupancy in step 125, and determines whether the user has occupancy based on the detection information from the occupancy sensor 94 in step 126.

[0075] When it is determined in step 126 that the user has already boarded the vehicle, the controller 90 determines in step 127 whether the adjusted wheelbase is appropriate by calculating the distance between the passenger's back and the seating sensor 94. Whether the wheelbase is appropriate can be determined by comparing the distance with preset information.

[0076] If the wheelbase is determined to be unsuitable in step 127, the controller 90 controls the telescopic drive unit 50 to be operated in step 128 to readjust the wheelbase. For example, if only one user is riding, and the distance between the passenger's back and the occupancy sensor 94 exceeds a set range, the wheelbase can be adjusted to accommodate a single passenger in step 128.

[0077] because Figure 11 The control method in steps 129 to 135 of the example can be compared with Figure 9 The examples are basically the same, so a description of them will be omitted.

[0078] As is evident from the foregoing, the personal mobility device according to embodiments of the present disclosure can easily adjust its wheelbase in response to changes in the number of passengers or the amount of cargo, since the front and rear vehicle bodies can be slidably connected, and the wheelbase can be changed by the operation of the telescopic drive unit and the locking device.

[0079] Furthermore, personal mobile devices according to embodiments of the present disclosure can be conveniently used because the wheelbase can be automatically adjusted based on the detection of user access sensors or information input by the user.

[0080] While this disclosure has been described in conjunction with certain embodiments, it should be understood that it is not intended to limit the invention to those particular embodiments. Rather, it is intended to cover all alternative modifications and equivalents included within the spirit and scope of this disclosure as defined by the appended claims.
