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 to 12, an embodiment of the present invention discloses a terminal device, which may include a middle frame 110, a rear case 120, a display screen 200, a functional part 300, and a driving mechanism 400.

The display screen 200 may be mounted on the middle frame 110. Optionally, the middle frame 110 and the rear housing 120 are each provided with a groove 130, and the groove 130 is used for accommodating at least a part of the functional component 300, which may be specifically arranged on the top, bottom or side of the terminal device. Of course, according to the specific structure of the functional component 300, the position, size, and other structural parameters of the groove 130 can be flexibly selected, which is not limited in the embodiment of the present invention.

The functional part 300 is reversibly disposed on an outer surface of the terminal apparatus. That is, the functional block 300 may be flipped such that the orientation of the functional block 300 may be changed to meet the operational requirements of the functional block 300 in different states. Alternatively, the functional component 300 may be disposed on the middle frame 110, which may be turned relative to the middle frame 110 to improve the structural strength of the functional component 300. In the embodiment of the present invention, the functional unit 300 may include at least one of a camera assembly, a sensor, a fingerprint recognition module, a receiver, and a fill-in light.

As described above, at least a portion of the functional component 300 may be located in the groove 130, and since the groove 130 is recessed in the thickness direction of the terminal device, the location of the functional component 300 in the groove 130 may reduce the space occupied by the functional component 300 in the thickness direction. Preferably, the depth of the recess 130 may be made equal to the thickness of the camera head assembly so that the camera head assembly does not protrude as far as possible with respect to the middle frame 110 and the rear case 120. When the thickness of the terminal device needs to be controlled within a certain range, the groove 130 is provided to reserve a larger thickness for the functional component 300, so that the device included in the functional component 300 can be selected more flexibly. Taking the example where the functional component 300 includes a camera assembly, the camera 320 included in the camera assembly may be larger, so as to obtain better shooting effect.

A driving mechanism 400 is provided in the terminal device, the driving mechanism 400 for driving the functional unit 300 to be turned over includes a driving source 410, a first driving shaft 420, and an elastic member 430. The driving source 410 is used for providing power, and the driving source 410 may specifically include a driving motor 412 and a speed reducer 413, and the speed reducer 413 has a power output shaft 411, and the power output shaft 411 may rotate under the driving action of the driving motor 412 to output power. The driving source 410 is connected to the first driving shaft 420, and specifically, the power output shaft 411 of the driving source 410 is connected to the first driving shaft 420, so as to drive the first driving shaft 420 to rotate. The elastic member 430 has a first end connected to the first driving shaft 420 and a second end connected to the functional part 300. The driving source 410 may drive the functional part 300 to be switched between different orientations by the first driving shaft 420 and the elastic member 430. Specifically, the power output shaft 411 of the driving source 410 drives the first driving shaft 420 to rotate, and the first driving shaft 420 may apply a torque to the elastic member 430, so that the elastic member 430 is deformed, and when the elastic member 430 is deformed to a certain extent, the functional component 300 is driven to rotate.

The drive mechanism 400 described above can drive the functional component 300 to flip over so that the functional component 300 can be switched between different orientations. Therefore, the functional unit 300 may not occupy the space of the display area, so that the screen ratio of the terminal device is high. Meanwhile, the state of the functional component 300 can be switched by only driving the functional component 300 to rotate by the driving mechanism 400, the movement form of the functional component 300 is simpler, and a plurality of driving mechanisms 400 are not required to be arranged so as to cause the functional component 300 to move in different forms. Therefore, the space occupied by the driving mechanism 400 is reduced, which is beneficial to the structural design of the terminal equipment, and meanwhile, the cost of the terminal equipment can be reduced, and the thickness of the whole terminal equipment is reduced.

In addition, when the acting force is transmitted through the elastic member 430, the elastic member 430 may play a role of buffering, and prevent the functional component 300 from hard collision with other components when rotating, so the elastic member 430 may protect the functional component 300, and the service life of the functional component 300 may be prolonged.

Taking the functional component 300 including a camera assembly as an example, in the process of driving the camera assembly to rotate by the driving mechanism 400, the camera assembly may stay in a state facing the front side of the terminal device (i.e., the side where the display screen 200 is located) and a state facing the rear side of the terminal device (i.e., the side away from the display screen 200), so as to respectively complete the front-end shooting and the rear-end shooting. Therefore, a space for installing the front camera is not required to be reserved in the display area of the terminal equipment, and favorable conditions are provided for the development of the terminal equipment to the full screen direction. It should be noted that, when the terminal device does not need to perform front shooting, the camera assembly can be turned over to the rear side of the terminal device.

As shown in fig. 11 and 12, in order to more reliably drive the functional component 300 to rotate, the driving mechanism 400 in the embodiment of the present invention may further include a second driving shaft 440, where the second driving shaft 440 is fixed relative to the functional component 300 in a rotation direction of the second driving shaft 440, that is, the second driving shaft 440 may drive the functional component 300 to rotate when rotating, and a connection manner of the two may be an interference fit, a key-and-slot fit, or the like. The second end of the elastic member 430 is connected to the second driving shaft 440, and the connection manner may be welding, connection by a fastener, or the like. In contrast, the connection between the elastic member 430 and the second driving shaft 440 is easier to achieve, so that the connection reliability between the elastic member 430 and the second driving shaft 440 is easier to ensure, and the connection reliability between the second driving shaft 440 and the functional component 300 is easier to ensure, thereby achieving the aforementioned purpose.

In the embodiment of the present invention, in order to improve the buffering effect and ensure the turning sensitivity of the functional component 300, the elastic member 430 may preferably be a spring. At this time, at least a portion of the first driving shaft 420 may be positioned within the spring, and at least a portion of the second driving shaft 440 may be positioned within the spring. At this time, the first driving shaft 420 and the second driving shaft 440 may be disposed side by side inside the spring. A certain gap can be reserved between one end of the functional component 300 and the first driving shaft 420, so that the first driving shaft 420 can support the functional component 300, but cannot directly drive the functional component 300 to rotate; the other end of the functional component 300 and the second driving shaft 440 may be directly fixed, so that the second driving shaft 440 can support the functional component 300 and also directly drive the functional component 300 to rotate. This structure can make the functional unit 300 and the driving mechanism 400 more compact, occupy less space, and make the overall thickness of the terminal device smaller.

Further, to facilitate the arrangement of the functional component 300 and the drive mechanism 400, the axis of the first drive shaft 420 may be parallel to the axis of the second drive shaft 440, or the axis of the first drive shaft 420 may coincide with the axis of the second drive shaft 440.

The first driving shaft 420 and the second driving shaft 440 may not contact each other, and stability and rotatable function of the first driving shaft 420 and the second driving shaft 440 may be ensured by providing support structures at corresponding positions of the functional part 300, respectively. However, in order to simplify the structure of the terminal device, a positioning groove (not shown) may be formed at one end of the first driving shaft 420 (specifically, the end far from the driving source 410), and one end of the second driving shaft 440 may be engaged with the positioning groove to connect the first driving shaft 420 and the second driving shaft 440 to each other, so that a corresponding support structure does not need to be provided on the functional component 300. It should be noted that even though the first driving shaft 420 and the second driving shaft 440 are connected to each other, the first driving shaft 420 does not drive the second driving shaft 440 to rotate. For example, the positioning groove may be a circular groove.

When the functional component 300 includes a camera head assembly, the camera head assembly may specifically include a camera head bracket 310, a camera head 320 mounted on the camera head bracket 310, a lens 330 mounted on the camera head bracket 310, and a foam 340 disposed between the camera head 320 and the lens 330. The number of the cameras 320 may be one, or two or more cameras may be provided to improve the imaging effect. The lens 330 may be adhered to the camera bracket 310 by a double-sided adhesive tape 350, and the lens 330 may cover the camera 320 to protect the camera 320. The foam 340 can improve the sealing performance between the camera 320 and the lens 330, and prevent impurities such as liquid, dust and the like in the external environment from entering the camera 320. The driving source 410 may drive the camera holder 310 to switch between a state of facing the front side of the terminal apparatus and a state of facing the rear side of the terminal apparatus to implement front shooting and rear shooting, respectively.

In the embodiment of the present invention, the camera holder 310 may have a first accommodating space 311 and a second accommodating space 312, the camera 320 is located in the first accommodating space 311, and at least a portion of the first driving shaft 420 and at least a portion of the second driving shaft 440 are located in the second accommodating space 312. The camera head 320 can be spaced apart from the first driving shaft 420 and the second driving shaft 440, so that the first driving shaft 420, the second driving shaft 440 and the elastic member 430 do not substantially interfere with the camera head 320 when moving, thereby ensuring the imaging effect of the camera head assembly and prolonging the service life of the camera head assembly.

Further, the camera holder 310 may further open a communication passage 313, and the first receiving space 311 and the second receiving space 312 communicate with each other through the communication passage 313. There is a gap between the outer surface of at least one of the first and

second driving shafts

420 and 440 and the inner surface of the second receiving space 312. The camera assembly may further include a flexible circuit board (not shown in the figure), one end of the flexible circuit board is connected to the camera 320, and the other end of the flexible circuit board sequentially passes through the communication channel 313 and the gap and is connected to a circuit board of the terminal device, so that the camera 320 is electrically connected to the circuit board, the circuit board supplies power to the camera 320, and controls the state of the camera 320. The flexible circuit board can deform, so that the flexible circuit board can be well adapted to the rotation of the camera assembly, and the flexible circuit board is introduced into the terminal equipment through the communicating channel 313 and the second accommodating space 312, so that the possibility that the flexible circuit board is exposed when the camera assembly rotates can be reduced as much as possible, and the appearance texture of the terminal equipment is improved, and the user experience is improved.

In order to further reduce the influence of the camera assembly on the flexible circuit board, the flexible circuit board can be arranged in a linear structure with a small width. For example, the deformation degree of the flexible circuit board can be reduced when the camera assembly rotates by adopting the structure, so that the flexible circuit board is not easy to be damaged due to repeated deformation or excessive deformation.

In an alternative embodiment, the driving mechanism 400 may further include a first gear 450 and a second gear 460 engaged with each other, the first gear 450 being disposed on the power output shaft 411 of the driving source 410, and the second gear 460 being disposed on the first driving shaft 420. The distances between the first gear 450 and the second gear 460 and the top of the middle frame 110 may not be equal, so that the first driving shaft 420 may be closer to the top of the middle frame 110 than the driving source 410, so that the driving source 410 may maintain a sufficient distance from the top of the middle frame 110, thereby facilitating the arrangement of the driving mechanism 400 and other components within the terminal device. Alternatively, the first gear 450 and the second gear 460 may each be provided as a spur gear, a helical gear, a herringbone gear, or the like.

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.

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.

The above description is only an example of the present invention, and is not intended to limit the present invention.
