The present invention relates to a communication terminal capable of automatically or manually operating a rotating camera module and a rotating camera module used therein, and more particularly, to a camera unit and a driving unit according to deformation of an elastic body provided in a power transmission unit. The present invention relates to a communication terminal having a rotatable camera module capable of automatically and manually rotating a camera unit by selectively transmitting power therebetween, and a rotatable camera module used therein.

As a typical mobile mobile terminal has recently diversified its functions, the mobile phone has additionally implemented a function of taking a picture or video with a camera in addition to a call function, which is an original function of a mobile phone.

Conventionally, the camera is fixed to a mobile phone, but in this case, when the user shoots a picture or video in a direction different from the direction in which the camera lens is fixed, the user needs to rotate the mobile phone body to correct the direction of the camera lens. In the case of rotating the main body, there was a problem that the user could not immediately check the image displayed on the LCD screen.

In order to solve this problem, the camera mounted on the mobile phone is generally mounted in a rotatable structure to the mobile phone in order to facilitate the user's convenience in taking pictures or videos.

As described above, there are manual and automatic methods for rotating the rotatable camera, but in the case of manual, the user has to rotate the camera manually. In particular, when the camera is mounted on the sliding side of the slide phone and the sliding is made, it is extremely difficult to rotate the camera with one hand because the position of the camera is relatively far.

Figure 1a is a folding mobile phone that can drive the camera automatically to solve the problem of the conventional mobile phone equipped with a manual rotary camera is shown.

That is, as shown in Figure 1a, the foldable cell phone has a first main body 10, the display means 13 is installed, and a control module (not shown) for implementing various functions of the mobile phone is built in a plurality of operations It consists of the 2nd main body 20 provided with the button 22. As shown in FIG.

On the other hand, the first body 10 and the second body 20 is connected to rotate through the hinge portion is configured to open and close the second body 20 as the first body 10 rotates. In this case, a camera is built in the hinge unit, and the camera may be rotatably mounted to a portion of the first body or the second body in some cases.

FIG. 1B is an enlarged partial cutaway view of a portion “A” of the hinge portion of FIG. 1A, and illustrates that the camera is mounted in the hinge portion 11 formed in the first body 10.

That is, as shown in FIG. 1B, the hinge portion 11 includes a camera 31 and at least one lens 32 installed in the housing 31 and the housing 31. ), The geared motor 40 is fixed to the shaft.

Thus, the camera 30 is configured to rotate in the hinge portion 11 as the geared motor 40 is driven and its axis is rotated.

On the other hand, the camera 30 is configured to be electrically connected to the display unit 13 and the control module (not shown) built in the second body 20 and the like through the flexible printed circuit 34, the signal is transmitted, The control module (not shown) is also electrically connected to the geared motor 40 and configured to selectively drive the geared motor 40 by applying power to the geared motor 40.

At this time, the operation of the camera 30 and the geared motor 40 is made by the control module (not shown) through the operation buttons 22 formed on the second body 20, the rotation of the camera 30 Guides 12 are mounted for guiding and / or anti-overturning roles.

However, the above-described folding type mobile phone equipped with a rotating camera has a structure in which the camera housing 30 is directly connected to the shaft of the geared motor 40 so that the geared motor 40 may be rotated in order to rotate the camera 30. Driving was essential.

Therefore, since the camera 30 is configured to rotate only by the geared motor 40, there is a problem in that the current is excessively consumed and the use time of the mobile phone battery is excessively shortened.

In particular, when an external force is applied during the automatic operation, the rotation operation is not completed, and thus current is continuously supplied to the geared motor 40 before the external force is removed, thereby causing a large current consumption.

In addition, the camera 30 having the above-described structure does not have a means for manually rotating the camera 30, so that manual rotation of the camera 30 is impossible, which hinders the user's convenience.

In order to solve this problem, the gear ratio of the geared motor 40 may be reduced by rotating the camera 30 manually, but in this case, the housing 31 and the geared motor (directly connected to the geared motor 40) There is a fear that 40) is broken, the rotation is not smooth and the rotation is not good.

As shown in FIG. 3, the power transmission unit 500 includes a hinge shaft 530, a guide cam 510, and an elastic body 520, and selectively transmits power depending on whether the elastic body 520 is deformed. .

The hinge shaft 530 is fixed to the drive shaft 410 of the drive means 400 through the opening 531 formed in the center.

In this case, the hinge shaft 530 has symmetrical cross sections at predetermined angles and has side surfaces 533 and 534 having a predetermined thickness extending in the driving shaft direction.

The elastic body 520 has a shape corresponding to the side surface 534 of the hinge shaft 530. At this time, the elastic body 520 is preferably made of a leaf spring to contact the side surface 534 of the hinge shaft 530 through a large area.

In this case, the guide cam 510 may be formed separately from the housing 310 and fixed to the housing 310, but it is preferable that the guide cam 510 is integrally formed with the housing 310 for convenience of manufacturing.

Preferably, the elastic force of the elastic body 520 is less than the force acting between the elastic body 520 and the hinge shaft 530 by an external force and the elastic body 520 and the driving force of the driving means 400 It must be greater than the force acting between the hinge shafts (530).

As a result, the power transmission unit 500 is compressed and returned to its original position by contacting the hinge shaft 530 whenever the camera unit 300 is rotated by a predetermined angle in the manual operation. As a result, the driving means 400 may be prevented from rotating, thereby preventing damage to the driving means 400.

In addition, the elastic body 520 is in contact with the side surface (534,534) of the hinge shaft 530, the hinge shaft 530 and the guide cam 510 when the relative rotation of the hinge shaft 530 perpendicular to the axis of rotation In the direction of pressure.

By the elastic pressing force, the hinge shaft 530 and the elastic body 520 try to maintain a 'stable state', wherein the 'stable state' is between the elastic body 520 and the hinge shaft 530. It means a state in which the elastic pressing force of the working elastic body 520 is zero.

As shown in FIG. 4A, the elastic body 520 is preloaded and installed in a convex shape convex toward the rotation axis, and the hinge shaft 530 is recessed to correspond to the arc shape of the elastic body 520. The long radius portion 533 is formed to protrude more than the portion 534.

When the elastic body 520 and the long radius portion 533 are in contact with each other, as shown in FIG. 5B, the elastic pressing force is applied to be in a stable state.

In addition, as shown in FIG. 4, in consideration of the fact that the rotation angle of the camera unit 300 is about 180 degrees, it is preferable to maintain a stable state every 180 degrees.

At this time, the hinge shaft 530 is made of a 180-degree symmetrical shape, the elastic body 520 is installed on the two guide cams 510 corresponding to the side surface 534 of the hinge shaft 530.

Alternatively, as shown in FIG. 6, the hinge shaft 530a and the elastic body 520a may be configured to maintain a stable state every 120 degrees, and as shown in FIG. 7, the hinge shaft 530b may be maintained at a stable state every 90 degrees. ) And the elastic body 520b.

In addition, the hinge shaft 530 and the elastic body 520 of various shapes may be configured to maintain a stable state at various angles.

Preferably, the present invention is a sensor unit 600 for detecting that the hinge shaft 530 rotates a predetermined angle with respect to the driving means 400 in order to control the completion of the rotation operation of the camera unit 300. It further includes.

As illustrated in FIG. 5, the sensor part 600 may include a first brush and a second brush so as to be energized at a predetermined angle through electrical contact with the brush housing (not shown) formed by protruding the brush 620 and the brush 620. The pattern is formed of a rectifying housing 610 spaced apart.

That is, as the brush housing (not shown) and the rectifying housing 610 rotate relative to each other by the rotation of the driving means 400, the first of the rectifying housing 610 by the brush 620 of the brush housing. When the pattern and the second pattern are electrically connected to each other at predetermined angles, the driving stop signal is applied to the driving controller (not shown).

At this time, the brush housing and the brush 620 is installed on the hinge shaft 530, as shown in Figure 5, the rectifying housing 620 may be installed on the side of the drive means 400, it may be installed on the contrary Do.

Preferably, when the camera unit 300 is designed to rotate about 180 degrees, the driving control unit when the first pattern and the second pattern of the rectifying housing are electrically connected every 180 degrees and energized by the brush of the brush housing. The driving stop signal can be applied.

On the other hand, the shape of the first pattern and the second pattern and the number of brushes 620 may be variously formed so as to be energized for each desired angle as is known. That is, when the first pattern and the second pattern are energized by the brush 620 at a phase of 360 degrees, the two patterns may be energized every 180 degrees by using the two brushes 620.

On the other hand, the present invention may further include a control means (not shown) for controlling the rotation of the forward and reverse direction of the camera unit 300.

The control means may be provided with a position sensing target (not shown) on the outer circumferential surface of the housing 310 of the camera unit 300, and at least two position sensing means on the main body 100, 200 corresponding to the outer circumferential surface of the housing 310. (Not shown) can be installed.

That is, the position detecting means may be installed to correspond to the position detecting target on the main body 100 and 200 corresponding to the portion where the rotation of the camera unit 300 starts and ends.

Through the position detection target and the position detection means, it is possible to control the forward and reverse rotation of the camera unit 300.

In this case, when the position sensing means is configured as a non-contact sensor, the position sensing means is configured as a sensing sensor switched when a magnetic field is detected, and the target for position sensing should be configured as a magnet that emits a magnetic field. In this case, the sensing sensor may be of various kinds, such as a Hall sensor consisting of Hall IC, a sensor using a magnetoresistive element (MR element).

The operation of one embodiment of the present invention having the above configuration will be described with reference to FIGS. 4 and 5.

Here, (a) in Fig. 4 is a stable state in which the guide cam is 0 degrees with respect to the hinge shaft, (b) is a state in which the guide cam is rotated 90 degrees with respect to the hinge shaft, and (c) is 180 degrees with respect to the hinge shaft. Fig. 5 shows a stable state, respectively, in Fig. 5 (a) shows a stable state in which the guide cam is 0 degrees with respect to the hinge shaft, and (b) shows a state where the guide cam is rotated 90 degrees with respect to the hinge shaft.

The rotatable camera module 1 according to the present invention has a function of not only automatic and manual operation but also safe operation, and according to the rotation angle of the camera unit 300, which is initially set, the hinge shaft 530, the elastic body 520, the sensor The arrangement or shape of the unit 500 may vary, but the basic principle is the same.

Hereinafter, the case where the camera unit 300 rotates within a 180 degree range will be mainly described.

First, automatic operation is performed as follows.

When the driving means 400 is applied to the driving signal, the driving means 400 determines the current position of the camera unit 300 by the position sensing means and the position sensing target and determines the driving direction of the driving means 400. Done.

When the driving means 400 rotates, a driving force is transmitted to the hinge shaft 530 by the driving shaft 410, and the force applied to the elastic body 520 by the driving force is smaller than the elastic force of the elastic body 520. The elastic body 520 is rotated while the guide cam 510 and the camera unit 300 remain undeformed (states of FIGS. 4A and 5A).

In this case, when the hinge shaft 530 rotates 180 degrees with respect to the driving means 400, a driving stop signal is applied to the driving means 400 (the power is cut off), and the driving means 400 is driven. Rotation of the camera unit 300 is completed.

If, by design, the rotation angle of the camera unit 300 is set within 180 degrees, for example, when set to 150 degrees, the camera unit 300 operates within a range of 15 degrees to 165 degrees, Since the protrusion stopper 350 is prevented from rotating by one end of the guide 120 formed in the main body, the stopper 350 can maintain a state of 15 degrees and 165 degrees. In this case, since some elastic force remains between the elastic body 520 and the hinge shaft 530, there is an advantage that it is not sensitive to extremely small external forces. In this case, the driving stop signal is applied to the driving means 400 only after the 180 degree rotation of the hinge shaft 530 is completed. However, the camera unit 300 is prevented from being rotated by the stopper 350. As described above, the state of 15 degrees and 165 degrees can be maintained.

Next, let's take a look at the manual operation.

When the user applies an external force to rotate the camera unit 300, the driving means 400 and the hinge shaft 530 are fixed, so that the elastic body 520 is deformed by the external force.

That is, the elastic body 520 is deformed from the state of 0 degrees in FIG. 4A to the state of 90 degrees in FIG. 4B.

If the user removes the external force before the state (90 degrees) of Figs. 4b and 5b, the guide cam 510 is returned to the state of Figs. 4a and 5a so that the camera unit 300 returns to its original position. If the external force is removed after the state (90 degree) of Figs. 4b and 5b, even if there is no additional external force, it becomes the state (180 degree) of Fig. 4c and the rotation of the camera unit 300 is completed.

In addition, when an external force is applied to the camera unit 300 during the automatic operation, a safe operation is possible.

That is, when an external force greater than the driving force is applied while the camera unit 300 is rotated by the driving means 400, the hinge shaft 530 is continuously rotated while the elastic body 520 is deformed as in the case of manual operation. You lose.

Therefore, after the hinge shaft 530 rotates 180 degrees, a driving stop signal is applied to the driving means 400. At this time, if the state of the elastic body 520 and the hinge shaft 530 is earlier than 90 degrees, the driving stop signal is returned to its original state. After 90 degrees, the elastic force of the elastic body 520 acts in the direction in which the rotation is completed, thereby maintaining a stable state of 0 degrees and 180 degrees.

Through such a safe operation there is an advantage that can prevent the current consumption of the drive means (400).

As described above, according to the present invention, the power transmission unit is provided between the camera unit and the driving means, so that not only the automatic rotation of the camera unit by the driving unit but also the manual rotation of the soft feeling is possible by the deformation of the elastic body of the power transmission unit. .

In addition, even if the camera unit is rotated only by a certain angle, since the manual rotation operation is completed, there is an effect that can be easily implemented manual operation.

In addition, the power transmission part is short in length, so the mounting space is extremely small, so that the automatic and manual can be stably implemented at the same time, and can be miniaturized. Will be.

While the invention has been shown and described with respect to particular embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as set forth in the claims below.
