DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0011] For ease of explanation, "front", "rear", "left", "right", "upper" and "lower" are defined below as shown in Figs. 1 to 8. The "front-rear direction", "left-right direction" and "upper direction" are perpendicular to each other. The "front-rear direction", "left-right direction" and "upper direction" are directions seen by a user sitting in the driver's seat or passenger seat of a vehicle. The "front-rear direction" corresponds to the "axial direction" of the present invention.

[0012] (First embodiment) 1 and 2 is a device that is installed on an instrument panel of a vehicle or the like and holds a smartphone 2. As shown in Fig. 1, the holding device 1 includes a holding unit 3 that holds the smartphone 2, a rotating unit 4 that rotates the holding unit 3 around an axis along the front-rear direction, a holding unit 5 that holds the rotating unit 4, and an in-vehicle ECU (Electronic Control Unit) 6 (see Fig. 2) that serves as a rotation control unit that controls the rotation of the rotating unit 4 based on vehicle information that indicates the state of the vehicle.

[0013] The smartphone 2 has a display screen 21 on the front side, and a magnet or a ferromagnetic material such as iron that is attracted to a magnet is built in on the back side.

[0014] As shown in FIG. 1, the holder 3 has a permanent magnet 8 and an electromagnet 9 serving as a first electromagnet.

[0015] The permanent magnet 8 is provided in a disk shape arranged perpendicular to the front-rear direction, and is provided so as to attract a ferromagnetic material or a magnet built into the smartphone 2. In this embodiment, the permanent magnet 8 has its south pole and north pole aligned along the front-rear direction. That is, the permanent magnet 8 is provided so that the magnetization direction is along the front-rear direction.

[0016] The electromagnet 9 is provided in a ring shape, and the permanent magnet 8 is fitted and fixed in the center. In this embodiment, the electromagnet 9 has a coil (not shown) wound around an axis along the front-rear direction, and is provided with N poles and S poles arranged along the front-rear direction, similar to the permanent magnet 8. That is, the electromagnet 9 is provided so that the magnetization direction is along the front-rear direction. When a current is passed through the coil of the electromagnet 9 so that the coil has the same magnetization direction as the permanent magnet 8, a magnetic force is generated that attracts the smartphone 2 to the electromagnet 9. When a current is passed through the coil of the electromagnet 9 so that the coil has a magnetization direction opposite to that of the permanent magnet 8, a magnetic force is generated that repels the smartphone 2 from the electromagnet 9.

[0017] The rotating unit 4 includes a rotating shaft that rotates around an axis along the front-rear direction, and a motor (neither shown) that rotates the rotating shaft. The rear end of the rotating shaft is fixed to a permanent magnet 8, and when the rotating shaft is rotated by the motor, the permanent magnet 8 and the electromagnet 9 fixed to the permanent magnet 8 also rotate around an axis along the front-rear direction. When the permanent magnet 8 rotates, the smartphone 2 also rotates.

[0018] The holding portion 5 is fixed to, for example, an instrument panel of a vehicle, and holds the rotating portion 4.

[0019] 2, the in-vehicle ECU 6 is connected to the coil of the electromagnet 9 and the motor of the rotating unit 4, and controls the magnetic force of the electromagnet 9 and the rotation of the rotating unit 4. The in-vehicle ECU 6 is connected to a data communication unit 10 that enables communication with an in-vehicle network such as an in-vehicle LAN. The in-vehicle ECU 6 receives vehicle information (e.g., shift information indicating the position of the shift lever, on / off information of the ignition switch, vehicle speed information, etc.) from the in-vehicle network via the data communication unit 10.

[0020] The in-vehicle ECU 6 is connected to a data communication unit 11 that enables communication with the smartphone 2. The in-vehicle ECU 6 receives electronic device information (model and type number information of the smartphone 2) and attitude information (whether the smartphone 2 is placed vertically or horizontally) from the smartphone 2 via the data communication unit 11.

[0021] Next, a procedure for using the holding device 1 having the above-mentioned configuration will be described. The user brings the permanent magnet 8 or electromagnet 9 close to the rear surface of the smartphone 2. As a result, the smartphone 2 is attracted to the permanent magnet 8 or electromagnet 9 by the magnetic force of the permanent magnet 8 or electromagnet 9, and is held by the holding unit 3.

[0022] Next, the control operation of the rotating unit 4 of the holding device 1 having the above-mentioned configuration will be described below with reference to FIG. 3. First, when the ignition switch is turned on, the in-vehicle ECU 6 starts processing and takes in shift information (S1). If the shift information indicates that the position of the shift lever is R, that is, that the vehicle is moving backward (Y in S2), the in-vehicle ECU 6 controls the rotating unit 4 so that the smartphone 2 is placed horizontally as shown in FIG. 4 (S3). When the smartphone 2 is placed horizontally, the longitudinal direction of the display screen 21 is aligned with the left-right direction. In S3, the in-vehicle ECU 6 communicates with the smartphone 2 to obtain attitude information, and if the attitude information indicates the horizontal orientation, the rotating unit 4 is not rotated, and if the attitude information indicates the vertical orientation, the rotating unit 4 is rotated to place the smartphone 2 horizontally.

[0023] When the shift lever is in the R position, the smartphone 2 is used as a rear monitor by communicating with the in-vehicle network to receive video from a camera mounted on the rear of the vehicle and displaying the video on the display screen 21. It is easier to use the smartphone 2 as a rear monitor when the smartphone 2 is placed horizontally as shown in FIG. 4.

[0024] On the other hand, when the position of the shift lever is other than R, that is, when the vehicle does not move backward (N in S2), the in-vehicle ECU 6 controls the rotation unit 4 so that the smartphone 2 is placed vertically as shown in FIG. 5 (S4). When the smartphone 2 is placed vertically, the longitudinal direction of the display screen 21 is aligned with the up-down direction. As a result, when the smartphone 2 is not used as a rear monitor, the smartphone 2 can be placed vertically as in normal use. In S4, the in-vehicle ECU 6 communicates with the smartphone 2 to obtain attitude information, and if the attitude information indicates the vertical orientation, the rotation unit 4 is not rotated, and if the attitude information indicates the horizontal orientation, the rotation unit 4 is rotated to place the smartphone 2 vertically.

[0025] Next, if the ignition switch is not off (N in S5), the in-vehicle ECU 6 returns to S2. On the other hand, if the ignition switch is off (Y in S5), the in-vehicle ECU 6 determines whether the removal angle (predetermined rotation position) of the smartphone 2 has been set by the user (S6).

[0026] More specifically, the user can use an app for the holding device 1 to communicate with the in-vehicle ECU 6 and set the removal angle to an angle at which the user can easily remove the smartphone 2. The removal angle is, for example, the angle between the up-down direction and the longitudinal direction of the display screen 21. If the removal angle has been set by the user (Y in S6), the in-vehicle ECU 6 rotates the rotating unit 4 to the removal angle set by the user (S7) and then ends the process.

[0027] If the set angle has not been set in advance (N in S6), the in-vehicle ECU 6 rotates the rotating unit 4 to the vertical position (removal angle=90°) as shown in FIG. 5 (S8), and then ends the process.

[0028] Next, the control operation of the electromagnet 9 of the holding device 1 configured as described above will be described below. The on-board ECU 6 functions as an electromagnet control unit and controls the electromagnet 9. The on-board ECU 6 retrieves shift information and speed information in response to the ignition switch being turned on. When the shift information and speed information indicate that the vehicle is traveling, the on-board ECU 6 controls the electromagnet 9 to increase the adhesive force of the smartphone 2 to the holding unit 3, and when the shift information and speed information indicate that the vehicle is stopped, the on-board ECU 6 controls the electromagnet 9 to decrease the adhesive force of the smartphone 2 to the holding unit 3.

[0029] As a result, while the vehicle is moving, the smartphone 2 can be firmly attached and held by the holding part 3. Furthermore, while the vehicle is stopped, the adhesive force of the smartphone 2 to the holding part 3 weakens, making it easy to remove the smartphone 2.

[0030] Specifically, while the vehicle is running and while the vehicle is stopped, the in-vehicle ECU 6 passes a current through the coil of the electromagnet 9 so that the magnetization direction of the electromagnet 9 is the same as that of the permanent magnet 8, and the amount of current through the coil while the vehicle is stopped is less than the amount of current through the coil while the vehicle is running. This makes it possible to make the adhesive force of the smartphone 2 while the vehicle is stopped weaker than the adhesive force of the smartphone 2 while the vehicle is moving.

[0031] Furthermore, the on-board ECU 6 may pass a current through the coil of the electromagnet 9 while the vehicle is moving so that the magnetization direction of the electromagnet 9 is the same as that of the permanent magnet 8, and may reverse the direction of the current flowing through the coil while the vehicle is stopped so that the magnetization direction of the electromagnet 9 is opposite to that of the permanent magnet 8. In this case, a magnetic force that repels the smartphone 2 is generated in the electromagnet 9, and the adhesive force of the smartphone 2 while the vehicle is stopped can be further weakened.

[0032] Furthermore, the in-vehicle ECU 6 receives model and model number information through communication with the smartphone 2. Since the weight of the smartphone 2 is known from the model and model number information, the in-vehicle ECU 6 may control the electromagnet 9 so that the adhesive force for the smartphone 2 increases as the weight increases.

[0033] According to the above-described first embodiment, the in-vehicle ECU 6 controls the rotation of the rotating unit 4 in accordance with vehicle information indicating the state of the vehicle, so that the smartphone 2 can be rotated in accordance with the state of the vehicle without any operation by the user.

[0034] According to the above-described first embodiment, when the vehicle is moving backward, the smartphone 2 is placed horizontally (the longitudinal direction of the display screen 21 is arranged along the left-right direction), making it easy to use as a rear monitor. When the vehicle is not moving backward, the smartphone 2 is placed vertically (the longitudinal direction of the display screen 21 is arranged along the up-down direction), allowing the smartphone 2 to be arranged in the same manner as in normal use.

[0035] According to the above-described first embodiment, the in-vehicle ECU 6 controls the magnetic force of the electromagnet 9 so that the force of attraction of the smartphone 2 by the holder 3 is weakened while the vehicle is stopped, and controls the magnetic force of the electromagnet 9 so that the force of attraction of the smartphone 2 by the holder 3 is increased while the vehicle is moving. This increases the force of attraction of the smartphone 2 by the holder 3 while the vehicle is moving, and prevents the smartphone 2 from falling off the holding device 1. When the vehicle is stopped, the force of attraction of the smartphone 2 by the holder 3 is weakened, and the smartphone 2 can be easily removed from the holding device 1.

[0036] Second embodiment Next, a holding device 1B according to a second embodiment will be described below with reference to Fig. 6. In Fig. 6, parts equivalent to those of the holding device 1 shown in Fig. 1 and the like already described in the first embodiment are given the same reference numerals, and detailed description thereof will be omitted.

[0037] As shown in the figure, the holding device 1B includes a holding unit 3B that holds a smartphone 2, a rotating unit 4B, a holding unit 5, and an in-vehicle ECU 6. In the second embodiment, the holding unit 3B includes a permanent magnet 8 and an electromagnet 9B. The positioning member 7 and the permanent magnet 8 are similar to those in the first embodiment, and therefore detailed description thereof will be omitted here.

[0038] The electromagnet 9B is provided in a ring shape, and the permanent magnet 8 is fitted and fixed in the center. The electromagnet 9B has a coil (not shown) wound so that the magnetization direction is an axial direction along the front-rear direction, and N poles and S poles are arranged alternately along the axial direction. In this embodiment, the electromagnet 9B is provided with two N poles and two S poles. The rotating unit 4B includes a rotating shaft 12 and an electromagnet 13 as a second electromagnet. The rotating shaft 12 is fixed to the permanent magnet 8 and held by the holding unit 5 so as to be rotatable around the axial direction along the front-rear direction.

[0039] Electromagnet 13 is held by holding portion 5 and disposed at a position facing electromagnet 9B in the front-rear direction. Electromagnet 13 has a coil (not shown) wound around an axis along the front-rear direction, and has an N pole and an S pole arranged side by side along the front-rear direction. On-vehicle ECU 6 controls electromagnet 13 so that the magnetization direction is alternately switched so that the rear side is the N pole, the front side is the S pole, the rear side is the S pole, and the front side is the N pole.

[0040] As a result, for example, when the smartphone 2 is in a vertical position, the S pole of the electromagnet 9B and the electromagnet 13 face each other. At this time, when the rear side of the electromagnet 13 is controlled to be the N pole, the rotation stops and the smartphone 2 can be held in a vertical position. When the rear side of the electromagnet 13 is switched to the S pole, the electromagnet 9B and the electromagnet 13 repel each other, generating a rotational force, rotating the rotation shaft 12, and rotating the smartphone 2 to a horizontal position. When the smartphone 2 is rotated to a horizontal position, the N pole of the electromagnet 9B and the S pole of the electromagnet 13 face each other in the front-rear direction, stopping the rotation and holding the smartphone 2 in a horizontal position.

[0041] As in the first embodiment, the in-vehicle ECU 6 controls the electromagnet 9B so that the adhesive force of the smartphone 2 to the holder 3B becomes strong while the vehicle is traveling, and controls the electromagnet 9B so that the adhesive force of the smartphone 2 to the holder 3B becomes weak while the vehicle is stopped. This makes it possible to rotate the holder 3B by using the electromagnet 9B for holding the smartphone 2.

[0042] Third embodiment Next, a holding device 1C of a third embodiment will be described below with reference to Figures 7 and 8. In Figures 7 and 8, parts equivalent to those of the holding device 1 shown in Figure 1 and the like already described in the first embodiment above are designated by the same reference numerals, and detailed description thereof will be omitted.

[0043] As shown in the figure, the holding device 1C includes a holding unit 3C that holds a smartphone 2, a rotating unit 4C, a holding unit 5C, and an in-vehicle ECU 6. In the third embodiment, the holding unit 3C includes a positioning member 7C, a permanent magnet 8C, and an electromagnet 9C.

[0044] The positioning member 7C has a flat plate portion 71C, a pair of restricting plates 72C, 72C, a restricting plate 73C, a pair of locking arms 74C, 74C, and a positioning protrusion 75C. The flat plate portion 71C is formed in a rectangular shape, and a hole 76C is provided in the center into which the rear end of an electromagnet 9C described later is fitted. The pair of restricting plates 72C, 72C are provided standing from both ends of the flat plate portion 71C in the short side direction toward the front side, and restrict the movement of the smartphone 2 in the short side direction. The restricting plate 73C is provided standing from one end of the flat plate portion 71C in the long side direction toward the front side, and restricts the movement of the smartphone 2 in the long side direction.

[0045] The pair of locking arms 74C, 74C stand upright from the flat plate portion 71C toward the front side, and have locking claws at their tips that lock with the electromagnet 9C in the front-rear direction. The pair of locking arms 74C, 74C are arranged side by side along the longitudinal direction of the flat plate portion 71C. The positioning protrusion 75C is provided to protrude toward the front side from the flat plate portion 71C.

[0046] The permanent magnet 8C is provided in a disk shape, and unlike the first embodiment, no positioning hole is provided. The electromagnet 9C is provided in a ring shape as in the first embodiment, and the permanent magnet 8C is fixed to the center. A positioning groove 91C is provided on the side of the electromagnet 9C along the front-rear direction, into which the positioning protrusion 75C is fitted. By fitting the positioning protrusion 75C of the positioning member 7C into the positioning groove 91C of the electromagnet 9C, when the electromagnet 9C rotates, the positioning member 7C also rotates.

[0047] The rotating unit 4C has a rotating shaft 14, a gear 15, a gear 16, a rotating shaft 17, and a motor (not shown). The rotating shaft 14 is held by the holding unit 5C so as to be rotatable about an axis along the front-rear direction, and its rear end is fixed to the permanent magnet 8C. The gear 15 is attached to the rotating shaft 14. The gear 16 is attached to the rotating shaft 17 so as to mesh with the gear 15. The rotating shaft 17 is rotated by the motor about the axis along the front-rear direction. When the rotating shaft 17 is rotated by the motor, the rotational force is transmitted to the rotating shaft 17 via the gears 15 and 16, and the permanent magnet 8C can be rotated.

[0048] According to the above-described third embodiment, it is not necessary to fix the positioning member 7C to the smartphone 2, and this is easy to use.

[0049] The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, etc. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary as long as the present invention can be achieved, and are not limited.

[0050] In the above-described embodiment, the electronic device is described by taking the smartphone 2 as an example, but the present invention is not limited to this. The electronic device may be any device having a display screen, such as a tablet.

[0051] According to the above-described embodiment, the holders 3, 3B, and 3C attract and hold the smartphone 2 by the magnetic force of the permanent magnets 8 and 8C, but the present invention is not limited to this. The holder may have any structure capable of holding the smartphone 2, and may hold the smartphone 2 by sandwiching both sides of the smartphone 2 in the short side direction, for example.

[0052] The rotation control of the smartphone 2 is not limited to the above-described embodiment. For example, when using a navigation app of the smartphone 2, the in-vehicle ECU 6 may control the rotation of the rotation unit 4 so that the smartphone 2 is oriented vertically when going straight and is oriented horizontally when turning right or left. Specifically, the in-vehicle ECU 6 communicates with the smartphone 2 to obtain navigation information, and when the navigation information indicates a straight-ahead direction, controls the rotation unit 4 so that the smartphone 2 is oriented vertically.

[0053] In addition, in response to a right / left turn instruction from the navigation information or the operation of the turn switch, the in-vehicle ECU 6 determines that it is time to turn right or left and controls the rotation unit 4 so that the smartphone 2 is placed horizontally. At this time, the rotation angle and rotation speed of the smartphone 2 may be controlled in conjunction with information from a steering angle sensor. By placing the smartphone horizontally when turning right or left, the user can check map information of the destination after turning, and more information can be provided to the user.

[0054] When the right or left turn is completed, the in-vehicle ECU 6 returns the smartphone 2 to the vertical position. Completion of the right or left turn can be performed based on vehicle position information and information from the steering angle sensor. When returning the smartphone 2 from the horizontal position to the vertical position, the in-vehicle ECU 6 may also control the rotation angle and rotation speed of the smartphone 2 in conjunction with information from the steering angle sensor.

[0055] Furthermore, the smartphone 2 may be rotated according to the vehicle state, such as the vehicle position information and speed, and the type of application. The screen orientation that is easy to view differs depending on the application. When it is determined that the smartphone 2 is traveling in cooperation with the speed information and a navigation application is being used, the in-vehicle ECU 6 places the smartphone 2 vertically. When a video playback application is being used on the smartphone 2 while the vehicle is stopped, the in-vehicle ECU 6 places the smartphone 2 horizontally. Furthermore, when a video playback application is being used on the smartphone 2 while the vehicle is traveling, the in-vehicle ECU 6 may place the smartphone 2 vertically to make it difficult for the user to watch videos.

[0056] Furthermore, when a navigation app on the smartphone 2 is being used during delivery work, the in-vehicle ECU 6 places the smartphone 2 vertically. Then, when it is determined that the delivery destination is nearby, the smartphone 2 switches to a delivery management app. At this time, the in-vehicle ECU 6 places the smartphone 2 horizontally. When it is determined from speed information and vehicle ignition information that the vehicle has stopped to deliver a package to the delivery destination, the in-vehicle ECU 6 places the smartphone 2 vertically so that it is easy to remove. There are multiple ways to switch applications, such as by touch operation on the smartphone 2 or by switching between voice operations.

[0057] Moreover, the smartphone 2 may be placed vertically or horizontally depending on the type of application being used on the smartphone 2. For example, when a navigation application, a map application, an SNS application, or a phone call is being used, the smartphone 2 is placed vertically. Also, when a video playback application, an image / video shooting application, a data management application (delivery management), a game, or the like is being used, the smartphone 2 is placed horizontally.
