Abstract

A terminal holding device is installed in a mobile body such as, for example, a vehicle and holds a terminal device. The terminal holding device is mounted to a mounting surface such as the dashboard of the vehicle by a mounting section functioning as the base for the mounting. A holding section for holding the terminal device has a rotation mechanism, and the rotation mechanism rotates a sensor board so that the vertical direction of the sensor board is maintained. The configuration enables the sensor board to be horizontally maintained regardless of the rotational angle of the holding section for holding the terminal device, and as a result, the sensor can perform accurate detection.

Description

Terminal holding device

The present invention relates to a terminal holding device that installs a terminal device on a moving body.

In recent years, portable navigation devices have become widespread. Patent Document 1 describes an example in which a portable navigation device is installed in a vehicle using a cradle.

On the other hand, in recent years, portable terminal devices such as high-function mobile phones called “smartphones” have been installed and used on mobile objects such as vehicles. An application similar to a navigation device has been proposed for a smartphone, and the smartphone can be installed in a vehicle and used as a navigation device. However, although a smartphone has a GPS function, it often does not have a sensor such as a gyro sensor. For this reason, there has been proposed a technique for realizing a highly accurate navigation function by incorporating a gyro sensor or the like in a cradle and supplying the output to a smartphone.

Generally, the gyro sensor has a property that the detection accuracy is lowered unless it is installed horizontally with respect to the ground. When the gyro sensor is built in the cradle, the user freely rotates the cradle with the smartphone attached so that the smartphone is in a portrait or landscape orientation. The sensor is not always in a horizontal state. When the smartphone is rotated together with the cradle and the gyro sensor is tilted, the gyro sensor cannot accurately detect angular velocity, acceleration, and the like.

Although the device for installing a gyro sensor horizontally with respect to a vehicle is described in Patent Documents 2 and 3, when a device with a built-in gyro sensor rotates, the user is not aware of the state of the sensor. It has not been studied to keep the gyro sensor in a horizontal state.

FIG. 1 shows a terminal holding device 1 according to an embodiment of the present invention. The terminal holding device 1 functions as a so-called cradle, and a terminal device 50 such as a smartphone is attached.

FIG. 1 shows the terminal holding device 1 in a state where the terminal device 50 is held. Specifically, FIG. 1A is a front view of the terminal holding device 1, FIG. 1B is a side view of the terminal holding device 1, and FIG. 1C is a rear view of the terminal holding device 1. It is. FIG. 1B shows a state in which the inside of the terminal holder 50 is seen through.

As shown in the figure, the terminal holding device 1 includes a base 11, a hinge 12, an arm 13, a ball link 14, and a terminal holder 20.

The base 11 functions as a base when the terminal holding device 1 is attached to a moving body such as a vehicle. For example, a suction cup or an adhesive tape is provided on the lower surface of the base 11, and the base 11 is fixed to an installation surface 5 such as a dashboard of the vehicle by the adhesive tape.

The hinge 12 is fixed to the arm 13 and is rotatably attached to the base 11. As the hinge 12 rotates, the arm 13 rotates in the front-rear direction of the terminal device 50, that is, in the directions of the

arrows

61 and 62 in FIG. That is, the installation angle of the terminal holder 20 with respect to the installation surface 5 can be adjusted by rotating the arm 13 via the hinge 12 with respect to the base 11 fixed to the installation surface 5 of the vehicle.

The ball link 14 is attached to the upper end of the arm 13 and holds the terminal holder 20 at an arbitrary angle with respect to the arm 13.

The terminal holder 20 holds a sensor substrate such as a gyro sensor. Specifically, the terminal holder 20 includes a support shaft 21,

gear shafts

22 and 23, gears 24, 25 and 26, a sensor substrate 27, and a sensor 28. The support shaft 21, the

gear shafts

22 and 23, and the

gears

24, 25, and 26 constitute a rotation mechanism that rotates the terminal holder 20 with respect to the support shaft 21.

The sensor substrate 27 has a flat plate shape. A sensor 28 is provided on the sensor substrate 27. A preferred example of the sensor 28 is a gyro sensor that detects at least one of a horizontal angular velocity and acceleration of a moving body.

Further, the terminal holder 20 holds the terminal device 50. The terminal holder 20 has a connector and wiring not shown. For example, the connector is provided on the front surface of the terminal holder 20, that is, on the bottom of the surface on which the terminal device 50 is installed, and is connected to the connector of the terminal device 50 when the terminal device 50 is installed on the terminal holder 20. The connector is electrically connected to the sensor substrate 27 by wiring. Therefore, the detection signal from the sensor 28 is supplied to the terminal device 50 through the sensor substrate 27, the wiring, and the connector.

The terminal device 50 includes a display surface 51 having a display unit such as a liquid crystal display panel on the front side of the terminal device 50 main body, and a back surface 52 on the back side of the terminal device 50 main body. Normally, the terminal device 50 is configured in a rectangular flat plate shape, and the display surface 51 and the back surface 52 are made substantially parallel.

The terminal holder 20 has a contact surface 29 on the front side. When the terminal device 50 is attached to the terminal holder 20, the contact surface 29 abuts on the back surface 52 of the terminal device 50 and supports the back surface 52 of the terminal device 50. In the example of FIG. 1, the contact surface 29 of the terminal holder 20 is configured such that the entire surface contacts the back surface 52 of the terminal device 50. Instead, one or several portions of the contact surface 29 may be partially protruded, and only the protruded portion may be in contact with the back surface 52 of the terminal device 50.

In addition, in said structure, the base 11 comprises the attaching part in this invention, and the hinge 12, the arm 13, and the ball link 14 comprise the support part in this invention. The terminal holder 20 constitutes a holding part in the present invention.

Next, the rotation mechanism of the terminal holder 20 will be described. The terminal holder 20 that holds the terminal device 50 is rotatable with respect to the support shaft 21, and can be fixed in a state in which the terminal holder 20 is rotated with respect to the support shaft 21 by an arbitrary angle. A state in which the terminal holder 20 rotates is shown in FIG. FIG. 2 shows a state in which the terminal device 50 is removed in FIG. 1A and the contact surface 29 of the terminal holder 20 is seen through. Specifically, FIG. 2A shows a state in which the terminal device 50 is arranged vertically with respect to the terminal holder 20, and this is a reference position, that is, a state in which the rotation angle of the terminal holder 20 is 0 degree. FIG. 2B shows a state in which the terminal holder 20 is rotated about 45 degrees clockwise with respect to the support shaft 21. FIG. 2C shows a state in which the terminal holder 20 is rotated about 90 degrees clockwise with respect to the support shaft 21. Note that, as described above, the terminal device 50 usually has a rectangular flat plate shape, and the vertically arranged state is an arrangement in which the longitudinal direction of the display surface 51 is vertically long. The arrangement is such that the longitudinal direction of the display surface 51 is horizontal.

1 and 2, the support shaft 21 is fixed to the ball link 14 and does not rotate. The gear 24 is fixed to the support shaft 21, and therefore the gear 24 does not rotate. A gear 25 is engaged with the gear 24. The gear 25 is rotatably fixed to the gear shaft 22, and the gear shaft 22 is fixed to the terminal holder 20. A gear 26 is engaged with the gear 25. The gear 26 is rotatably fixed to the gear shaft 23, and the gear shaft 23 is fixed to the terminal holder 20. The

gears

24, 25, and 26 are configured to have a gear ratio of 1: 1, that is, a gear ratio of 1: 1: 1.

A sensor board 27 is attached to the gear 26. The terminal holding device 1 is attached to the installation surface 5 so that the perpendicular direction V of the sensor substrate 27 is substantially perpendicular to the ground, which is a horizontal plane. The sensor substrate 27 has a flat plate shape, and the sensor 28 is provided thereon. As shown in FIG. 1B, the sensor substrate 27 is attached perpendicular to the gear 26. The

gears

24, 25, and 26 are all provided so as to be substantially parallel to the contact surface 29 of the terminal holder 20. The contact surface 29 is substantially parallel to the display surface 51 and the back surface 52 of the terminal device 50. Therefore, the sensor substrate 27 is provided substantially perpendicular to the display surface 51 and the back surface 52 of the terminal device 50 and the contact surface 29 of the terminal holder 20. In addition, the sensor substrate 27 is provided perpendicular to the longitudinal direction of the terminal device 50 at the reference position shown in FIG.

Now, as shown in FIG. 2B, when the terminal holder 20 is rotated clockwise (in the direction of the arrow 70) with respect to the support shaft 21 fixed to the ball link 14, the gear 24 is fixed to the support shaft 21. However, the gear 25 meshed with the gear 24 rotates clockwise (in the direction of the arrow 71). Accordingly, the gear 26 meshed with the gear 25 rotates counterclockwise (in the direction of the arrow 72). As a result, as illustrated, the perpendicular direction V of the sensor substrate 27 does not change, and the sensor substrate 27 maintains a horizontal state. That is, the perpendicular direction V of the sensor substrate 27 is maintained substantially perpendicular to the horizontal plane.

As shown in FIG. 2 (c), even if the terminal holder 20 is further rotated clockwise, the gear 25 is similarly rotated clockwise, and the gear 26 is rotated counterclockwise accordingly. As a result, the perpendicular direction V of the sensor substrate 27 does not change, and the sensor substrate 27 maintains a horizontal state. Further, even when the terminal holder 20 is rotated counterclockwise from the state shown in FIG. 2C, the perpendicular direction V of the sensor substrate 27 does not change and the sensor substrate 27 maintains the horizontal state.

Thus, in this embodiment, the three

gears

24, 25, and 26 are meshed, the gear 24 is fixed, and the gear ratio between the gear 24 and the gear 26 is set to 1: 1, so that the terminal holder 20 Regardless of the rotation angle, the perpendicular direction V of the sensor substrate 27 is always substantially perpendicular to the horizontal plane before and after the rotation.

Thus, according to the present embodiment, even when the terminal holder 20 of the terminal holding device 1 is rotated by an arbitrary rotation angle, the perpendicular direction of the sensor substrate 27 is always maintained before and after the rotation, and the sensor 28 is horizontal. Maintained. Therefore, once the terminal holding device 1 is attached to the installation surface 5 so that the sensor substrate 27 is substantially parallel to the horizontal plane, the sensor substrate 27 is horizontal regardless of the rotation angle of the holding portion that holds the terminal device 50. Therefore, the sensor 28 can detect accurately. In relation to the terminal device 50, when the terminal holder 20 is rotated, the sensor substrate 27 is always in a state perpendicular to the display surface 51, the back surface 52 of the terminal device 50, and the contact surface 29 of the terminal holder 20. maintain.

Thus, as a condition for the sensor substrate 27 to always maintain the horizontal state regardless of the rotation angle of the terminal holder 20, the gear 24 is fixed and the gear ratio between the gear 24 and the gear 26 is 1: 1. However, the gear ratio between the gear 25 and the

gears

24 and 26 may not be 1: 1. This is because the gear 25 only has a function of transmitting the rotation of the terminal holder 20 with respect to the fixed gear 24 to the gear 26. That is, when the terminal holder 20 is rotated, the rotation amount of the terminal holder 20 (the central axis in the longitudinal direction of the terminal holder 20) with respect to the fixed gear 24 is transmitted to the gear 26 through the gear 25, and the gear by that rotation amount. This is because 26 is rotated in the reverse direction. Therefore, the gear 25 can have any number of teeth. A plurality of gears may be provided instead of the gear 25.

In this embodiment, the gear 24 corresponds to the first gear of the present invention, the gear 26 corresponds to the second gear, and the gear 25 corresponds to the third gear.

[Modification]
Next, a modified example of the present invention will be described. In the above embodiment, the terminal holder 20 can be fixed in a state where it is rotated by an arbitrary angle with respect to the support shaft 21. In contrast, in the first modification described below, the terminal holder 20 can be fixed only in a state in which the terminal holder 20 is rotated with respect to the support shaft 21 in units of 90 degrees from the reference position. Further, the rotation mechanism for rotating the terminal holder 20 with respect to the support shaft 21 is constituted by two gears.

In addition, the structure for making it possible to fix only in the state which rotated the terminal holder 20 by the unit of 90 degree | times arrange | positions the member which is fixed with respect to the support shaft 21, and contacts the terminal holder 20, for example, the said member In the surface where the terminal holder 20 and the terminal holder 20 are in contact with each other, a structure may be provided in which irregularities or grooves and protrusions that are mutually fitted at every rotation angle of 90 degrees are provided.

FIG. 3 shows a rotation mechanism of the terminal holding device 1a according to the first modification. 3 is a view in which the terminal device 50 is removed and the contact surface 29 of the terminal holder 20 is seen through, as in FIG.

As shown in FIG. 3A, in the terminal holding device 1a according to the first modification, the rotating mechanism includes two gears 43 and 44. That is, two gears 43 and 44 are provided in place of the three

gears

24, 25 and 26 in the embodiment described with reference to FIGS. The gear ratio between the gear 43 and the gear 44 is 1: 1. That is, the number of teeth of the gear 43 and the number of teeth of the gear 44 are 1: 1.

The gear 43 corresponds to the gear 24 in the above embodiment, and is fixed to the support shaft 21 connected to the ball link 14. Therefore, the gear 43 does not rotate. The gear 44 meshes with the gear 43 and is rotatably fixed to the gear shaft 42. The gear shaft 42 is fixed to the terminal holder 20. Therefore, the gear 44 rotates as the terminal holder 20 rotates. A sensor substrate 27 is provided on the gear 44. A sensor 28 is attached to the sensor substrate 27.

Now, as shown in FIG. 3A, a state where the terminal device 50 is installed vertically is set as a reference position of the terminal holder 20. At this reference position, the sensor substrate 27 is horizontal, and the perpendicular direction V of the sensor substrate 27 is substantially perpendicular to the ground, which is a horizontal plane. Further, at this reference position, the sensor substrate 27 is perpendicular to the longitudinal direction of the terminal device 50 having a rectangular shape. Here, as shown in FIG. 3B, when the terminal holder 20 is rotated clockwise (in the direction of arrow 70), the gear 43 does not rotate, but the gear 44 rotates in the clockwise direction (in the direction of arrow 74). To do. When the terminal holder 20 is rotated 45 degrees clockwise, the rotation amount of the gear 44 is 1/8 rotation for rotation and 1/8 rotation for revolution, so the gear 44 rotates 1/4 when viewed from the outside. Looks. As a result, the sensor substrate 27 moves with the rotation of the gear 44, and is almost perpendicular to the ground. However, as described above, in the first modified example, the terminal holder 20 can be fixed only at the rotation position in units of 90 degrees from the reference position, and the terminal holder 20 is fixed in the state of FIG. There is nothing.

When the terminal holder 20 is further rotated clockwise, as shown in FIG. 3C, the terminal device 50 is in a horizontally long state, that is, in a state where the terminal holder 20 is rotated 90 degrees clockwise from the reference position. The terminal holder 20 can be fixed. When the terminal holder 20 is rotated 90 degrees clockwise, the amount of rotation of the gear 44 is ¼ rotation for rotation and ¼ rotation for revolution, and the gear 44 appears to be ½ rotation when viewed from the outside. In this state, the sensor substrate 27 is turned upside down compared to the reference position shown in FIG. 3A, but the sensor substrate 27 itself is in a horizontal state, and the perpendicular direction V of the sensor substrate 27 is It is substantially perpendicular to the ground, which is a horizontal plane. That is, in the state of FIGS. 3A and 3B in which the terminal holder 20 is fixed, the perpendicular direction V of the sensor substrate 27 is maintained. Thus, even if the sensor 28 is positioned below the sensor substrate 27, the sensor substrate 27 is in a horizontal state, so that the sensor 28 can be accurately detected. FIG. 4 shows a rotation mechanism of the terminal holding device 1b according to the second modification. In the second modification, the terminal holder 0 can be fixed only in a state where the terminal holder 20 is rotated with respect to the support shaft 21 in units of 45 degrees from the reference position.

FIG. 4 is a view in which the terminal device 50 is removed and the contact surface 29 of the terminal holder 20 is seen through similarly to FIG.

As shown in FIG. 4A, in the terminal holding device 1b according to the second modification, the rotation mechanism includes two

gears

53 and 54. The gear ratio between the gear 53 and the gear 54, that is, the ratio of the number of teeth is 3: 1.

The gear 53 corresponds to the gear 24 in the above embodiment, and is fixed to the support shaft 21 connected to the ball link 14. Therefore, the gear 53 does not rotate. The gear 54 meshes with the gear 53 and is rotatably fixed to the gear shaft 52. The gear shaft 52 is fixed to the terminal holder 20. Therefore, the gear 54 rotates as the terminal holder 20 rotates. A sensor board 27 is provided on the gear 54. A sensor 28 is attached to the sensor substrate 27.

Now, as shown in FIG. 4A, a state in which the terminal device 50 is installed vertically is set as a reference position of the terminal holder 20. At this reference position, the sensor substrate 27 is horizontal, and the perpendicular direction V of the sensor substrate 27 is substantially perpendicular to the ground, which is a horizontal plane. Further, at this reference position, the sensor substrate 27 is in a state perpendicular to the longitudinal direction of the terminal device 50 having a rectangular shape. Here, as shown in FIG. 4B, when the terminal holder 20 is rotated clockwise (in the direction of arrow 70), the gear 53 does not rotate, but the gear 54 rotates in the clockwise direction (in the direction of arrow 75). To do. The terminal holder 20 can be fixed in a state rotated 45 degrees clockwise. The amount of rotation of the gear 54 at that time is 3/8 rotation for rotation and 1/8 rotation for revolution, so the gear 54 appears to rotate 1/2 when viewed from the outside. As a result, the sensor substrate 27 moves with the rotation of the gear 44, and the sensor substrate 27 is turned upside down and is almost horizontal. That is, the perpendicular direction V of the sensor substrate 27 is substantially perpendicular to the ground, which is a horizontal plane. Thus, even if the sensor 28 is positioned below the sensor substrate 27, the sensor substrate 27 is in a horizontal state, so that the sensor 28 can be accurately detected.

Even when the terminal holder 20 is further rotated clockwise, as shown in FIG. 4C, the terminal device 50 is in a horizontally long state, that is, the terminal holder 20 is rotated 90 degrees clockwise from the reference position. The terminal holder 20 can be fixed. When the terminal holder 20 is rotated 90 degrees clockwise, the amount of rotation of the gear 54 is 3/4 rotation and 1/4 rotation, and the gear 54 appears to rotate once when viewed from the outside. In this state, the sensor substrate 27 is in a horizontal state as in the reference position shown in FIG. 4A, and the perpendicular direction V of the sensor substrate 27 is substantially perpendicular to the horizontal plane. Therefore, the sensor 28 can accurately detect.

As described above, in the second modified example, the terminal holder 50 can be fixed at the reference position where the terminal device 50 is arranged vertically or horizontally and the position rotated by 45 degrees from the reference position, and In a state where the terminal holder 20 can be fixed, the perpendicular direction of the sensor substrate 27 is maintained.

In the second modification, the terminal holder 20 can be fixed only in a state where the terminal holder 20 is rotated with respect to the support shaft 21 in units of 45 degrees from the reference position. However, the terminal holder 20 can be fixed by adjusting the gear ratio. As long as the sensor substrate 27 is horizontal in a possible state, the configuration is not limited to 45 degrees, and the terminal holder 20 may be fixed only in a state in which the terminal holder 20 is rotated with respect to the support shaft 21 at another predetermined angle. In general, since the user views the terminal holder in a fixed state, the sensor substrate 27 can always be kept horizontal in such a state.

In addition, although the case where the terminal holder 20 was rotated clockwise was demonstrated above, the case where the terminal holder 20 is rotated counterclockwise is the same. That is, in the first modified example, when the terminal holder 20 is rotated 90 degrees counterclockwise and fixed, the sensor substrate 27 is turned upside down and becomes horizontal. In the second modified example, when the terminal holder 20 is rotated 45 degrees counterclockwise and fixed, the sensor substrate 27 is in the same horizontal state as the reference position.

Further, in the above modification, as shown in FIG. 3A and FIG. 4A, the state in which the terminal device 50 is arranged vertically is used as the reference position, but FIG. 3C and FIG. As shown in FIG. 3A, the state in which the terminal device 50 is arranged horizontally is a reference position, and the state rotated 90 degrees counterclockwise from the reference position is the state shown in FIGS. You may think. In this case, at the reference position, the sensor substrate 27 is in a position perpendicular to the short direction of the terminal device.

As a method of fixing the terminal holder 20 at the reference position and a position rotated 45 degrees or 90 degrees from the reference position, for example, a method of locking the gear 44 or 54 by a latch or the like at those positions, a stopper or the like is provided. Various known methods such as a method of stopping the rotation of the rotary shaft 42 or 52 can be employed.

In the above embodiments and modifications, the rotation mechanism is constituted by a gear train, but instead, the rotation mechanism may be constituted by a pulley and a belt.
