Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1, an embodiment of the present invention discloses a terminal device, which specifically includes a housing, a camera module, a driving mechanism, a hall device 420, and a circuit board 700. The camera module can rotate relative to the shell, and comprises a camera 100; the driving mechanism is arranged in the shell and can drive the camera 100 to rotate; the circuit board 700 is disposed in the housing, and the circuit board 700 is connected to the camera head 100 to control an operating state of the camera head 100.

Alternatively, the driving mechanism may only drive the camera 100 to rotate, and at this time, the camera 100 may be always located inside the housing or may be always located outside the housing; the driving mechanism may also drive the camera 100 to extend out of the housing first, and then drive the camera 100 to rotate. By adopting the two structures, the occupation condition of the camera 100 on the display area of the terminal equipment can be relieved, and the screen occupation ratio of the terminal equipment is further improved.

In the embodiment of the present invention, the camera module includes, in addition to the camera 100, a bracket 200, a rotating shaft 300, a spiral body 500, and a magnetic element 410, where the magnetic element 410 may be a magnet.

The bracket 200 is a mounting base of the camera 100 and the rotating shaft 300, and when the driving mechanism only drives the camera 100 to rotate, the bracket 200 can be fixedly connected with the shell; when the driving mechanism can drive the camera 100 to extend out and retract relative to the shell, and also can drive the camera 100 to rotate relative to the shell, the bracket 200 can be movably connected with the shell, one part of the driving mechanism is directly arranged on the shell, the part can drive the bracket 200 to move, and further drive the camera 100 to extend out or retract relative to the shell, the other part of the driving mechanism is arranged on the bracket 200, and when the bracket 200 drives the camera 100 to extend out of the shell, the other part of the driving mechanism can drive the camera 100 to rotate.

The rotating shaft 300 is rotatably disposed on the bracket 200, and is fixedly connected to the camera head 100, so that the rotating shaft 300 can drive the camera head 100 to rotate. When the camera head 100 can extend and retract relative to the housing, a through hole is formed in the housing, and the rotating shaft 300 can be parallel to the axis of the through hole or perpendicular to the axis of the through hole. The aforementioned driving mechanism is connected to the rotary shaft 300 and drives the rotary shaft 300 to rotate.

The first end of the spiral body 500 is fixedly connected with the rotating shaft 300, and the magnetic element 410 is fixedly connected with the second end of the spiral body 500. Therefore, in the case that the rotating shaft 300 rotates with the camera head 100, the screw 500 and the magnetic element 410 rotate with the rotating shaft 300, so that the rotation angle of the camera head 100 is obtained through the magnetic element 410, and the rotation angle of the camera head 100 is controlled more accurately. Therefore, the structure can improve the user experience of the terminal equipment.

Specifically, the hall device 420 is disposed in the housing at a position corresponding to the magnetic element 410, and the hall device 420 is used in cooperation with the magnetic element 410, so that the rotation angle of the camera head 100 can be obtained. Alternatively, in order to improve the detection accuracy, the hall device 420 may be provided in the housing at a position facing the magnetic element 410. In the embodiment of the present invention, optionally, the hall device 420 may be mounted on the bracket 200, and when the driving mechanism only drives the camera 100 to rotate, the hall device 420 is fixed relative to the housing, so that the distance between the hall device 420 and the magnetic element 410 is not substantially changed; when the camera head 100 can be extended and retracted relative to the housing, the hall device 420 can move with the support 200 such that the distance between the hall device 420 and the magnetic element 410 is not substantially changed.

The camera module may further include a connection line 600, and the connection line 600 may enable electrical connection between the camera 100 and the circuit board 700 of the terminal device. In order to facilitate the arrangement of the connection line 600, the rotation shaft 300 may be provided as a hollow shaft, and one end of the connection line 600 may be connected to the camera head 100, and the other end may pass through the rotation shaft 300 to be connected to the circuit board 700. As a result, the connecting wire 600 is likely to interfere with the magnetic element 410, and the magnetic element 410 is not easy to be disposed.

In order to solve the above problem, a spiral gap is formed between two adjacent turns of the spiral body 500, one end of the connection line 600 is electrically connected to the camera 100, and the other end of the connection line passes through the spiral gaps of the rotary shaft 300 and the spiral body 500 in sequence and is electrically connected to the circuit board 700 of the terminal device. After the spiral body 500 is arranged, the requirement of angle detection can be met, and the connection between the connecting wire 600 and the circuit board 700 cannot be influenced, so that the camera 100 can rotate at any rotation angle.

Optionally, structures such as a light supplement lamp, an acoustic device and a sensor can be integrated in the camera module, so that the screen ratio of the terminal device is further improved.

As shown in fig. 1 and 2, in an alternative embodiment, the spiral 500 may include a first spiral section 510, a second spiral section 520, and a third spiral section 530 connected in series. The first spiral section 510 is fixedly connected with the rotating shaft 300, and specifically, the first spiral section 510 may be sleeved outside the rotating shaft 300; the magnetic element 410 is fixedly connected with the third spiral section 530, and particularly, the third spiral section 530 can be sleeved outside the magnetic element 410; one end of the connection wire 600 passes through the spiral gap of the second spiral section 520. In order to enhance the connection strength between the first spiral section 510 and the rotating shaft 300, the first spiral section 510 may be configured as a constant diameter section, so as to increase the contact area between the first spiral section 510 and the rotating shaft 300, thereby achieving the aforementioned effect. Similarly, in order to improve the connection strength of the third spiral section 530 and the magnetic element 410, the third spiral section 530 may be provided as a constant diameter section. It should be noted that the term "equal diameter" herein means that the inner diameter of each turn of the first spiral section 510 is equal, and the inner diameter of each turn of the third spiral section 530 is equal.

Considering that the size of the rotating shaft 300 is generally large and the size of the magnetic element 410 is small, the inner diameter of the first spiral section 510 can be made larger than the inner diameter of the third spiral section 530, so as to minimize the space occupied by the spiral body 500 for the arrangement of other components. At this time, in order to achieve the transitional coupling of the first spiral section 510 and the second spiral section 520, the inner diameter of the second spiral section 520 is gradually reduced in a direction in which the first spiral section 510 is directed toward the third spiral section 530.

As described above, the first and

second spiral sections

510 and 520 mainly serve to be connected to the rotating shaft 300 and the magnetic element 410, respectively, so that when the pitches of the first and

second spiral sections

510 and 520 are designed, the pitches of the first and second spiral sections can be made as small as possible, thereby increasing the contact area between the first spiral section 510 and the rotating shaft 300, and between the second spiral section 520 and the magnetic element 410 in a limited space. And the second spiral section 520 mainly provides one end of the connection wire 600 to pass through, so the pitch of the second spiral section 520 can be set larger to form a larger spiral gap for the connection wire 600 to pass through. In this regard, in the present embodiment, the pitch of the second helical section 520 is greater than the pitch of the first and third

helical sections

510 and 530.

In an alternative embodiment, the pitch of the first helical section 510 may be equal to the pitch of the second helical section 520, so that the structure of the screw 500 is simpler. Further, the turns of the first helical section 510 may be in direct contact, or a small gap may be left, so that the contact area of the first helical section 510 with the rotation shaft 300 tends to be maximized. Similarly, the turns of the third spiral section 530 may directly contact or leave a small gap, so that the contact area between the third spiral section 530 and the magnetic element 410 tends to be maximized.

As mentioned above, the second spiral section 520 mainly provides one end of the connection line 600 to pass through, so the pitch of the second spiral section 520 may be larger than the outer diameter of the connection line 600, so that the second spiral section 520 is not easy to apply a clamping force to the connection line 600, and further reduces friction between the two, and prevents the connection line 600 from being damaged due to excessive wear. Meanwhile, the arrangement can better ensure that the spiral body 500 and the rotating shaft 300 synchronously rotate, so that the accuracy of angle detection is improved. Further, the ratio of the pitch of the second spiral section 520 to the outer diameter of the connecting wire 600 can be set to 1.5-3, and the numerical range can prolong the service life of the connecting wire 600 and improve the accuracy of angle detection, and can make the structure of the second spiral section 520 relatively compact, so that the occupied space is smaller.

Specifically, the spiral body 500 may include a plurality of spiral units connected in series, with the head and tail ends of individual spiral units being adjacent and substantially aligned, with a spiral gap between adjacent spiral units, and the number of spiral units being indicative of the number of turns of the spiral body 500. Since a single spiral unit may contact the connection wire 600, in order to prevent the spiral unit from scratching or wearing the connection wire 600, the cross-sectional shape of the spiral unit may be set to be circular or elliptical, so that the contact surface of the spiral unit with the connection wire 600 is more rounded.

The terminal device disclosed by the embodiment of the invention can be a smart phone, a tablet computer, an electronic book reader or a wearable device. Of course, the terminal device may also be other devices, and the embodiment of the present invention is not limited thereto.

The embodiment of the invention also discloses an information processing method, which can be applied to the terminal equipment in any embodiment, and the method comprises the following steps:

s110, acquiring magnetic field information through the Hall device 420;

s210, the rotation angle of the camera 100 is determined based on the magnetic field information.

That is, when the camera head 100 rotates, the magnetic element 410 rotates relative to the hall device 420, the magnetic field of the magnetic element 410 changes, and the hall device 420 can obtain the rotation angle of the camera head 100 according to the change.

Optionally, to simplify the information processing method, the step S110 may specifically be: detecting the Hall value output by the Hall device 420; the step S210 may specifically be: and determining the rotation angle of the camera 100 corresponding to the hall value according to the hall value. The hall value may be specifically a magnetic field intensity variation value of the magnetic element 410, or may be other values that can obtain the rotation angle of the camera head 100. Specifically, the terminal device may pre-store a correspondence table between the hall value and the rotation angle of the camera 100, so that after the hall value output by the hall device 420 is obtained, the corresponding rotation angle can be obtained according to the hall value and the correspondence table.

Further, the above determining the rotation angle of the camera 100 corresponding to the hall value according to the hall value may specifically be: when the hall value output by the hall device 420 is the first threshold value, the rotation angle of the camera 100 is 0 °; when the hall value output by the hall device 420 is the second threshold value, the rotation angle of the camera 100 is 180 °. Alternatively, when the rotation angle of the camera 100 is 0 °, the camera 100 may be in the front shooting mode; when the rotation angle of the camera 100 is 180 °, the camera 100 may be in the rear photographing mode. The hall values may be vectors, so that when the rotation angle of the camera is 0 ° and 360 °, the specific values of the hall values may be the same, but there is a positive and negative division, so that the positions of the camera 100 when the rotation angle thereof is 0 ° and 180 ° can be distinguished.

Based on the information processing method described in any of the above embodiments, the terminal device may further include an obtaining module and a determining module, where the obtaining module is configured to obtain the magnetic field information through the hall device 420, and the determining module is configured to determine the rotation angle of the camera 100 according to the magnetic field information. Here, the acquisition module may be electrically connected to the hall device 420 to acquire the magnetic field information, and at the same time, the acquisition module may be electrically connected to the determination module so that the determination module may determine the rotation angle of the camera 100 according to the magnetic field information.

Further, the obtaining module is configured to detect a hall value output by the hall device 420 to obtain magnetic field information, and the determining module is configured to determine a rotation angle of the camera 100 corresponding to the hall value according to the hall value.

In this embodiment of the present invention, optionally, the terminal device may include a processor, a memory, and a computer program stored in the memory and capable of running on the processor, and when being executed by the processor, the computer program implements the information processing method according to any of the above embodiments.

In addition, the embodiment of the invention also discloses a computer readable storage medium, wherein a computer program is stored on the computer readable storage medium, and when the computer program is executed, the computer program realizes the information processing method of any one of the embodiments.

In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.
