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 and 2, an embodiment of the present invention discloses a mobile terminal, which may include a housing 100 and a camera module 200, where the camera module 200 is disposed on the housing 100. Specifically, the camera module 200 may be disposed on an outer surface of the housing 100.

As shown in fig. 1 to fig. 5, the camera module 200 disclosed in the embodiment of the present invention may specifically include a first bracket 210, a second bracket 220, a photosensitive assembly 230, and a camera 240. The first bracket 210 is a mounting base for other components included in the camera module 200, and the first bracket 210 is also an external component of the camera module 200. The second frame 220 is pivotally connected to the first frame 210 through a rotating shaft 250, so that the second frame 220 can rotate relative to the first frame 210, and a rotating plane of the second frame 220 can be a plane on which the second frame is located. Specifically, the rotation shaft 250 may be substantially perpendicular to both the first bracket 210 and the second bracket 220.

The photosensitive assembly 230 includes a circuit board 231 and a photosensitive device 232, and the circuit board 231 and the photosensitive device 232 are disposed on a surface of the first frame 210 facing the second frame 220. Specifically, the photosensitive device 232 may be disposed on a side of the circuit board 231 facing the first bracket 210, and the circuit board 231 may implement electrical connection between the photosensitive device 232 and a main board of the mobile terminal, so that the main board may obtain image information formed by the camera module 200 through the circuit board 231, and simultaneously control a working state of the camera module 200.

The cameras 240 are disposed on the second bracket 220, the number of the cameras 240 is at least two, and the number of the cameras 240 is greater than the number of the photosensitive assemblies 230. The specific type of each camera 240 may be different, for example, a wide-angle camera, a macro camera, a tele camera, and the like are included in the plurality of cameras 240. These cameras 240 can form images alone, also can make up the formation of image to reach effects such as degree of depth of field is supplementary, light filling, optics zoom, make the formation of image effect of module 200 of making a video recording better. The specific number of the cameras 240 can be flexibly set, and is not limited herein.

As described above, the second bracket 220 can rotate relative to the first bracket 210, and in the process of rotating the second bracket 220 relative to the first bracket 210, the second bracket 220 can drive the camera 240 to rotate, so that the position of the camera 240 relative to the photosensitive component 230 changes, and finally, the effect that the photosensitive component 230 can be aligned with different cameras 240 is achieved. In other words, when some of the cameras 240 are in the working state, the other part of the cameras 240 are in the non-working state, the cameras 240 which need to be in the working state are directly opposite to the photosensitive assembly 230, the cameras 240 which do not need to work can not be directly opposite to the photosensitive assembly 230, and when the part of the cameras 240 need to be switched to the working state, the second support 220 is driven to rotate, so that the part of the cameras 240 are directly opposite to the photosensitive assembly 230. Thus, different cameras 240 may share the same photosensitive assembly 230.

In summary, when the second bracket 220 drives the camera 240 to rotate, the circuit board 231 and the photosensitive assembly 230 can be aligned with different cameras 240, so as to meet the requirement of users for shooting by using different types of cameras 240. Since the number of the cameras 240 is greater than the number of the circuit boards 231 and the photosensitive devices 232, the number of the circuit boards 231 and the photosensitive devices 232 is reduced, thereby reducing the cost and power consumption of the camera module 200.

In a specific embodiment, the number of the photosensitive assemblies 230 may be set to one, and there is only one camera 240 in the active state at the same time. However, in order to improve the imaging effect, at least two cameras 240 may be in an operating state at the same time, and therefore, in the embodiment of the present invention, the number of the photosensitive assemblies 230 is set to be at least two, and each photosensitive assembly 230 is distributed at intervals on a circle with the rotation center of the second support 220 as a center. At this time, the plurality of cameras 240 may be arranged at intervals along the rotation direction of the second frame 220, and when the second frame 220 rotates, the rotation tracks of the plurality of cameras 240 substantially coincide with the arrangement positions of the photosensitive assemblies 230, so that each photosensitive assembly 230 may more conveniently face different cameras 240 at the same time.

Further, the plurality of photosensitive assemblies 230 include a first photosensitive assembly and a second photosensitive assembly, and the first photosensitive assembly and the second photosensitive assembly are distributed on two sides of the rotating shaft 250. That is, a center line between the first photosensitive member and the second photosensitive member substantially passes through the center line of the rotation shaft 250. In the process of rotating the second support 220 relative to the first support 210, the first photosensitive assembly and the second photosensitive assembly respectively face two different cameras 240. After so setting up, the distance between first sensitization subassembly and the second sensitization subassembly is prolonged to some extent for do not interfere with each other as far as possible between the camera 240 that is in operating condition simultaneously, thereby improve the formation of image effect.

In order to prevent dust, liquid, etc. in the external environment from damaging the camera module 200, the camera module 200 may further include a lens 260, the lens 260 is disposed on the first bracket 210, an installation space is defined by the first bracket 210 and the lens 260, and the second bracket 220, the photosensitive component 230, and the camera 240 are all located in the installation space. The installation space is relatively closed, so that the second bracket 220, the photosensitive assembly 230 and the camera 240 can be isolated from the external environment, thereby achieving the aforementioned purpose. Further, second bracket 220 is provided with a counter bore 221, the end of counter bore 221 facing lens 260 has a counter-sunk platform, rotating shaft 250 is connected with first bracket 210 through counter bore 221, and the end of rotating shaft 250 facing lens 260 is located in the counter-sunk platform. At this time, the shaft 250 does not protrude from the second bracket 220, so the shaft 250 does not occupy additional space in the camera module 200, and the camera module 200 can be designed to be thinner.

In the embodiment of the present invention, the rotation of the second bracket 220 with respect to the first bracket 210 may be manually performed. Specifically, the second bracket 220 may be provided with an operating lever extending out of the first bracket 210, and a user may rotate the second bracket 220 through the operating lever. However, this structure cannot ensure the rotation accuracy of the second cradle 220 on the one hand, and is also limited by the structure of the mobile terminal on the other hand, so that the rotation angle of the second cradle 220 is limited. To solve these problems, the camera module 200 according to the embodiment of the present invention may further include a driving mechanism (not shown in the drawings), which is disposed on the first frame 210 and connected to the second frame 220 to drive the second frame 220 to rotate. The driving mechanism can drive the second bracket 220 to rotate at any angle, so that the requirement that any camera 240 is right opposite to the photosensitive assembly 230 can be met. Meanwhile, the driving precision of the driving mechanism is higher, so that the target camera 240 can be aligned to the photosensitive assembly 230 more quickly and accurately.

Specifically, the driving mechanism may include a motor and a worm, the side surface of the second bracket 220 may be provided with a gear, the motor may drive the worm to rotate, and the worm is engaged with the gear, so as to drive the second bracket 220 to rotate.

The camera module 200 can be dismantled with casing 100 and be connected for camera module 200 can be changed, for example can set up the different multiple camera module 200 of structure, and the kind of the camera 240 that these camera module 200 contain can be different, and the user can change different camera module 200 according to the demand of difference, with the shooting demand that adapts to under more scenes. At least a part of the camera module 200 is located in the accommodating recess 120, so that the occupation of the camera module 200 on the thickness space of the mobile terminal can be reduced, and the whole mobile terminal is thinner. Further, after the camera module 200 is mounted on the housing 100, the entire camera module 200 may not protrude with respect to the first surface 110.

In an alternative embodiment, the receiving recess 120 has a first interface formed therein. The first bracket 210 is provided with an electrical connection end 211, and the electrical connection end 211 is plugged with the first interface under the condition that at least a part of the camera module 200 is positioned in the accommodating groove 120. That is to say, after the electrical connection end 211 is plugged into the first interface, the camera module 200 is not only physically connected to the housing 100, but also electrically connected to the housing 100, so that the arrangement can simplify the connection structure between the camera module 200 and the housing 100. In a case where at least a portion of the camera module 200 is located in the receiving recess 120, the camera 240 of the camera module 200 faces the rear surface of the mobile terminal, and thus rear shooting can be achieved.

In particular, the housing 100 may comprise a rim 130, the rim 130 being provided with a second interface 131. The electrical connection terminal 211 of the camera module 200 can be plugged with the second interface 131. That is, the camera module 200 may be inserted on the frame 130, for example, when the user holds the mobile terminal laterally, the camera module 200 may be inserted on the frame 130, thereby more conveniently performing a photographing operation. Further, the second interface 131 may be disposed at the bottom of the frame 130, where the bottom refers to the bottom of the frame 130 when the user holds the mobile terminal vertically. In the case where the electrical connection terminal 211 is plugged into the second interface 131, the camera module 200 faces a side away from the first surface 110. At this time, the camera 240 of the camera module 200 faces the user, so front shooting can be achieved. The camera used for realizing front shooting can be omitted by the arrangement, so that the structure of the mobile terminal is simpler, the cost is lower, and the screen occupation ratio of the mobile terminal is higher.

The structural form of the first interface and the second interface 131 can be flexibly selected, and in the embodiment of the present invention, in order to simplify the structure of the first interface and the second interface 131, both the first interface and the second interface 131 may be set as USB interfaces. Further, the second interface 131 may be a charging interface of the mobile terminal. When the camera module 200 is not plugged with the charging interface, the charging interface can realize the charging operation of the whole mobile terminal; when the camera module 200 is plugged with the charging interface, front-end shooting can be realized. Therefore, the conventional charging interface of the mobile terminal can be fully utilized to realize front shooting, and an additional interface does not need to be arranged on the shell 100, so that the number of open holes on the appearance surface of the shell 100 can be reduced, and the appearance texture of the mobile terminal is better.
