The use of an elevating camera is a specific implementation. The elevating camera can be hidden inside the casing of the terminal device, and the camera extends out of the casing when it needs to be used. However, the terminal device usually includes at least a front camera and a rear camera, and only one of the front camera and the rear camera can be raised and lowered. The more common way is that the front camera can be raised and lowered, and the rear camera is fixed. At this time, the rear camera still occupies the internal space of the case, resulting in a larger thickness of the terminal device, and its lightness and thinness need to be improved.

detailed description

To make the objectives, technical solutions, and advantages of the present disclosure more clear, the technical solutions of the present disclosure will be described clearly and completely in conjunction with specific embodiments of the present disclosure and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, but not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without making creative efforts fall within the protection scope of the present disclosure.

The technical solutions disclosed in the embodiments of the present disclosure will be described in detail below in conjunction with the drawings.

As shown in FIG. 1, some embodiments of the present disclosure disclose a terminal device, which includes a housing 100, a camera assembly 200 and a driving mechanism 300.

The casing 100 has a frame. For the housing 100 with different structures, the components forming the frame are different. For example, the case 100 may include a front case, a battery cover, and a middle frame disposed therebetween. The frame can be formed on the middle frame; in this case, the frame serves as a part of the middle frame. For another example, the housing 100 includes a front cover and a battery cover, and the frame may be formed on the front cover or the battery cover. In this embodiment, the housing 100 has an inner cavity 120, which in turn provides installation space for the components of the terminal device. Generally, the frame is provided with a perforation 110 which communicates with the inner cavity 120. The perforation 110 is used for the camera assembly 200 to pass through and out of the housing 100. Of course, the camera assembly 200 can also enter and exit the housing 100 through other channels, and is not limited to the perforation 110 formed in the frame.

The camera assembly 200 is movably disposed on the housing 100 and enters and exits the housing 100 through the perforation 110. When the camera assembly 200 moves out of the casing 100 through the perforation 110, shooting can be realized; when the camera assembly 200 moves into the casing 100 through the perforation 110, it is stored in the casing 100. This camera structure design does not need to open a hole corresponding to the lens on the display screen of the terminal device, that is, it does not occupy the display area of the terminal device, so the screen of the terminal device is relatively large.

The driving mechanism 300 is disposed in the housing 100, that is, in the inner cavity 120. The driving mechanism 300 is drivingly connected to the camera assembly 200, and is used to apply a rotational driving force to the camera assembly 200. Under the action of the rotational driving force, the camera assembly 200 rotates relative to the housing 100 with the central axis of the through-hole 110 as the rotation axis . The central axis of penetration here is the center line of the perforation 110, and the center line penetrates through the casing 100. When the camera assembly 200 rotates, the orientation of its camera will change, and then it can be oriented toward the front, back, or other positions of the terminal device according to user needs. Specifically, a corresponding control mechanism is provided in the terminal device, and the control mechanism can send a control signal to the driving mechanism 300, and the driving mechanism 300 drives the camera assembly 200 to rotate according to the control signal, so that the camera assembly 200 faces the front, back, or Other locations. It can be seen that the terminal device can realize front and rear shooting at the same time through the one camera assembly 200, and there is no need to separately set the front camera and the rear camera, so that the thickness of the terminal device is reduced, its lightness and thinness are improved, and the cost Will also be reduced accordingly. In addition, when the orientation of the camera assembly 200 is changed by means of rotation, no jamming phenomenon such as a black screen will occur, making the user experience better.

It should be noted that the lifting and rotation of the camera assembly 200 relative to the housing 100 can be achieved by different driving parts. The above-mentioned driving mechanism 300 can only be used to drive the rotation of the camera assembly 200, and the lifting of the camera assembly 200 can Through additional structure. In addition, the lifting and rotation of the camera assembly 200 can be realized in sequence, that is, the camera assembly 200 can be driven to extend out of the housing 100 first, and then the camera assembly 200 can be driven to rotate. However, these setting methods will cause the structure of the terminal device to be relatively complicated. Therefore, in order to simplify the structure of the terminal device, the lifting and rotation of the camera assembly 200 can also be achieved at the same time, that is, when the camera assembly 200 is driven to rotate, the camera is driven The assembly 200 extends out of the housing 100. In some embodiments of the present disclosure, the camera assembly 200 can rotate relative to the housing 100 and enter and exit the housing 100 with the through axis of the through-hole 110 as the rotation axis under the action of the rotational driving force. In other words, the rotational driving force output by the driving mechanism 300 has a first component force that drives the camera assembly 200 to rotate and a second component force that drives the camera assembly 200 to move up and down. The camera assembly 200 acts in conjunction with the first component force and the second component force The lower part rotates relative to the housing 100 and enters and exits the housing 100. At this time, the camera assembly 200 can be rotated up and down only by the driving mechanism 300 to achieve the foregoing purpose.

The camera assembly 200 may include a mounting base 210, a camera disposed on the mounting base 210, and an elevating rotating shaft 220 fixedly connected to the mounting base 210. The mounting base 210 and the elevating rotating shaft 220 may be provided as an integrated structure. The lifting rotating shaft 220 is provided with a first spiral structure, and the rotational driving force acts on the first spiral structure to drive the lifting rotating shaft 220 to rotate around its own axis and move along the direction of its own axis, which in turn drives the mounting base 210 to rotate and lift. The rotation and lifting of the camera are realized. The structure of the lifting shaft 220 is simpler, and it is easier to realize the simultaneous lifting and rotating.

The driving mechanism 300 may specifically include a driving source 310 and a driving shaft 320 drivingly connected to the driving source 310. A second spiral structure is provided on the driving shaft 320, and the second spiral structure meshes with the first spiral structure. By setting the thread density of the second spiral structure and the first spiral structure, the lifting height of the camera assembly can be adjusted. At this time, the structure of the driving shaft 320 is relatively simple, and the transmission connection between the driving shaft 320 and the lifting rotating shaft 220 is relatively easy to implement. Specifically, the driving source 310 may be a motor. In order to better drive the lifting shaft 220, the driving mechanism 300 may further include a reducer 330, and the power output by the motor is input to the reducer 330, and the reducer 330 is output through a transmission mechanism provided by itself The greater the torque, the torque acts on the drive shaft 320, which in turn drives the drive shaft 320 to rotate.

As long as the power transmission between the lifting shaft 220 and the driving shaft 320 can be achieved, the relative positions of the lifting shaft 220 and the driving shaft 320 can be flexibly set. In order to further improve the compactness of the terminal device, the axis of the lifting shaft 220 can be perpendicular to the axis of the driving shaft 320.

The camera included in the camera module 200 may be provided as only one camera, or as multiple cameras. When multiple cameras are set, each camera can be arranged at intervals. At this time, the parameters of each camera may be different to select different cameras to shoot according to different shooting environments and needs. Of course, the parameters of each camera can also be the same, but the positions of these cameras are different. When the mounting base 210 is at the same position, the directions of the cameras can be different, thereby obtaining images in more directions. In other embodiments, the parameters and setting positions of each camera can be arbitrarily selected and combined to meet different shooting needs.

In an optional embodiment, the plurality of cameras include at least a first camera 230 and a second camera 240, and the first camera 230 and the second camera 240 are arranged along the axis of the elevating rotation shaft 220. At this time, the orientations of the first camera 230 and the second camera 240 are basically the same, so the two can cooperate when shooting, thereby improving the shooting effect. Further, the camera assembly 200 further includes a flash 250 disposed on the mounting base 210. When the terminal device is in a dark environment, the flash 250 may emit light to achieve fill light, thereby improving the imaging effect.

The mounting base 210 may be a columnar structure, and its cross-sectional shape may be elliptical, circular, triangular, rectangular, etc., and the shape of the perforation 110 may also be elliptical, circular, triangular, rectangular, etc., as long as the installation The seat 210 can be rotated within the perforation 110. Of course, in addition to the mounting base 210 being able to rotate within the perforation 110, it is also necessary to consider sealing factors to prevent dust, liquid and other impurities in the external environment from entering the interior of the terminal device. Based on this, some embodiments of the present disclosure configure the mounting base 210 as a cylindrical structure, and the through hole 110 as a round hole, and the axial center line of the mounting base 210 and the axial center line of the through hole 110 are collinear. With this arrangement, the mounting base 210 can rotate within the through hole 110, and the gap between the two can be controlled within a relatively small range, thereby improving the sealing effect here.

In some embodiments of the present disclosure, the rotation angle of the camera assembly 200 may be an integer multiple of 90°, for example, the rotation angle may be set to 180°, 270°, 360°, and so on. When the rotation angle is an integer multiple of 360°, the shooting range that the camera assembly 200 can correspond to is wider, so it can meet more shooting needs of users. For example, when the camera assembly 200 extends out of the housing 100, by controlling the camera assembly 200 to rotate 360°, panoramic shooting can be achieved. In addition, when the camera assembly 200 rotates while lifting, since the camera assembly 200 needs to be lifted by rotation, the greater the angle of rotation of the camera assembly 200 during its entire movement, the more space it can drive The camera assembly 200 simultaneously realizes lifting and rotating.

The structures provided by some embodiments of the present disclosure can achieve better results when the terminal device is a single-sided screen structure, and when the terminal device adopts a double-sided screen structure, the effects brought by it will be more significant. At this time, the terminal device includes a first display screen and a second display screen, and the first display screen and the second display screen are both disposed on the casing, and the two are opposed along the thickness direction of the terminal device. No matter which of the first display screen and the second display screen is in use, the camera assembly 200 can be driven to rotate by the driving mechanism 300, thereby meeting the shooting requirements in the current state.

The terminal device disclosed in some embodiments of the present disclosure may be a smart phone, a tablet computer, an e-book reader, or a wearable device. Of course, the terminal device may also be other devices, and some embodiments of the present disclosure do not limit this.

The above embodiments of the present disclosure mainly describe the differences between the various embodiments. As long as there is no contradiction, the different optimization features between the various embodiments can be combined to form a better embodiment. Considering the conciseness of the text, here is No longer.

The above are only the embodiments of the present disclosure, and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and changes.
