Description

Terminal device

Technical Field

The invention relates to the technical field of communication equipment, in particular to terminal equipment.

Background

At present, more and more users prefer large-screen terminal devices, and accordingly, more and more terminal devices have larger and larger screen occupation ratio. Considering the portability of the terminal device, how to further increase the screen occupation ratio of the terminal device on the premise of determining the overall size of the terminal device is a main direction for manufacturers to research and develop.

In order to increase the screen occupation ratio of the terminal equipment, more terminal equipment designs the functional device into a structure capable of lifting or adjusts the terminal equipment into a sliding cover type terminal equipment so as to arrange the functional device on the sliding cover. The terminal equipment of these structures avoids the occupation of the face that the display screen is located through the position that changes the functional device, and then the area that the looks increased the display screen.

Also in order to increase the screen occupation ratio, referring to fig. 1 and 2, the terminal device related to the related art is designed such that the functional device 101 is in a flip-type structure, and during operation, the corresponding driving mechanism can drive the functional device 101 to flip from the back side of the terminal device to a position facing the front side of the terminal device, so as to be able to operate towards the front side of the terminal device, and the flip-over process of the functional device is as shown in fig. 3 to 7. Because the display screen of the terminal equipment is arranged on the front panel, the structure can also avoid the occupation of the functional device on the panel space where the display screen is positioned, and the screen occupation ratio of the terminal equipment can be increased. Of course, the functional device 101 can also be reset into a recess of the housing 102.

In order to enable the functional device 101 to be turned from the back side of the terminal device to the front side of the terminal device, the middle frame 1021 of the housing 102 needs to be provided with a notch 1022, and the existence of the notch 1022 can avoid the turning motion of the functional device 101. However, the gap 1022 may destroy the integrity of the middle frame 1021, may cause the strength of the middle frame 1021 to be weakened, and may also affect the appearance performance of the terminal device.

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.

Referring to fig. 8 to fig. 22, a terminal device according to an embodiment of the present invention is disclosed, and the disclosed terminal device includes a housing 100, a display 200, a first support 300, a second support 400, a driven device 500, a first driving mechanism 600, a second driving mechanism 700, and a third driving mechanism 800.

The housing 100 is a peripheral base member of the terminal device, and the housing 100 provides a mounting base for other components of the terminal device. In the embodiment of the invention, the housing 100 has a receiving groove 111.

The display screen 200 is located on a first surface of the housing 100, and a surface of the notch of the receiving groove 111 is located on a second surface, which is opposite to the first surface, that is, the notch of the receiving groove 111 faces opposite to the display screen 200. The receiving groove 111 is used for receiving the first bracket 300, the second bracket 400 and the driven device 500, and after the driven device 500 completes the work, the driven device can be received in the receiving groove 111 by the first bracket 300 and the second bracket 400.

The first bracket 300 is rotatably attached to the housing 100, and is rotatable with respect to the housing 100. The first bracket 300 can be accommodated in the accommodating groove 111 by being rotated; of course, the first bracket 300 is also rotated to move at least a part of its structure out of the notch of the receiving groove 111.

The second bracket 400 is rotatably mounted on the first bracket 300, and the second bracket 400 can rotate relative to the first bracket 300, so that the angle between the second bracket 400 and the first bracket 300 can be adjusted, and the driven device 500 can be driven to rotate continuously.

The driven device 500 is rotatably coupled to the second bracket 400, and the driven device 500 can rotate with respect to the second bracket 400. In the embodiment of the present invention, the driven device 500 may include at least one of a camera, a flash, a microphone, and a fingerprint recognition module, and of course, the embodiment of the present invention does not limit the specific kind of the driven device 500.

The first driving mechanism 600 is connected to the first frame 300, the first driving mechanism 600 drives the first frame 300 to rotate, and the first driving mechanism 600 drives the first frame 300 to rotate, so as to drive the second frame 400 and the driven device 500 to enter and exit the receiving groove 111.

The second driving mechanism 700 is connected to the second bracket 400, and the second driving mechanism 700 can drive the second bracket 400 to drive the driven device 500 to rotate, so as to change the orientation of the driven device 500, thereby enabling the driven device 500 to work towards the side where the display screen 200 is located.

The third driving mechanism 800 is connected to the driven device 500, and the third driving mechanism 800 drives the driven device 500 to rotate relative to the second bracket 400, so that the driven device 500 can be more flexibly adjusted in angle, and the driven device 500 can work in more angle ranges.

Referring to fig. 8 to fig. 13, the working process of the terminal device disclosed in the embodiment of the present invention is as follows:

when the driven device 500 needs to operate, the first driving mechanism 600 drives the first support 300 to rotate, the first support 300 can drive the second support 400 and the driven device 500 to rotate out of the accommodating groove 111, as shown in fig. 10 and 11, then the first driving mechanism 600 stops operating, the second driving mechanism 700 can drive the second support 400 to continue rotating, the second support 400 can drive the driven device 500 to continue rotating, and therefore the orientation of the driven device 500 can be changed, and finally the driven device is oriented to the side where the display screen 200 of the terminal device is located, as shown in fig. 12 and 13. Since the driven device 500 is rotatably connected to the second bracket 400, the driven device 500 is also driven by the third driving mechanism 800 to rotate relative to the second bracket 400, so as to adjust the working orientation thereof more flexibly, as shown in fig. 14-19.

When the driven device 500 completes the work, the third driving mechanism 800 drives the driven device 500 to reset, then the second driving mechanism 700 drives the second bracket 400 and the driven device 500 to reset together, and finally, under the driving of the first driving mechanism 600, the first bracket 300, the second bracket 400 and the driven device 500 are all folded in the accommodating groove 111, as shown in fig. 8 and 9.

As can be seen from the above working process, in the terminal device disclosed in the embodiment of the present invention, because the second bracket 400 can drive the driven device 500 to rotate relative to the first bracket 300, and further the orientation of the driven device 500 can be changed, and further the driven device 500 can be driven to face the side where the display screen 200 is located, in this case, the first bracket 300 does not need to rotate by an excessively large angle, the first bracket 300 can drive the second bracket 400 and the driven device 500 to be transferred out of the accommodating groove 111, and then the second bracket 400 can drive the driven device 500 to rotate, and further the driven device 500 can be driven to face the side where the display screen 200 is located, because the first bracket 300 does not need to turn to the side where the display screen 200 is located, that is, it is not necessary to form a gap on the housing 100 to avoid the movement of the first bracket 300 connected to the housing 100, and there is no problem that the strength of the housing is weak due to forming the gap and the appearance performance of the terminal device is poor .

In the embodiment of the present invention, the structure of the casing 100 may be various, and the casing 100 may include a middle frame 110, a battery cover 120 and a surrounding plate 130, where the battery cover 120 is disposed opposite to the display screen 200. The surrounding plate 130 is disposed in the middle frame 110, the surrounding plate 130 and the middle frame 110 form a sidewall of the receiving groove 111, and the battery cover 120 is mounted on a side of the middle frame 110 away from the display screen 200, so as to cover an internal structure of the middle frame 110. Specifically, the middle frame 110 may further have a bottom plate inside, and the bottom plate may be sealed at one end of the space enclosed by the enclosing plate 130 and the middle frame 110, so as to form the bottom wall of the accommodating groove 111, and of course, the casing 100 may further include a main plate upper cover sealed at one end of the space enclosed by the enclosing plate 130 and the middle frame 110, so as to form the bottom wall of the accommodating groove 111. The bottom wall refers to an inner wall of the receiving groove 111 facing the notch of the receiving groove 111.

The battery cover 120 is provided with an avoiding opening 121, and the avoiding opening 121 is arranged opposite to the notch of the accommodating groove 111, so that the accommodating groove 111 can be prevented from being shielded. The middle frame 110 has a certain thickness and is a main supporting frame of the case 100, and the receiving groove 111 has a certain depth, so that the receiving groove 111 is formed in the middle frame 110, which has an advantage of easy molding.

As described above, the rotation of the first bracket 300 can bring the second bracket 400 and the driven device 500 out of the receiving groove 111, and then the rotation of the second bracket 400 and the rotation of the driven device 500 can adjust the working angle of the driven device 500. Based on this, in a more preferable aspect, in a direction in which the first supporter 300 is rotated out of the receiving groove 111, the inner wall of the middle frame 110 may cooperate with the first supporter 300 to be limited, thereby preventing the first supporter 300 from being excessively rotated.

In this process, the first bracket 300 is rotated by an angle of typically 90 °.

The second stand 400 may also be perpendicular to the first stand 300 in a state where the second stand 400 faces the side where the display screen 200 is located. In the driving process, the second driving mechanism 700 only needs to drive the second bracket 400 to rotate 90 ° relative to the first bracket 300, and then the driven device 500 can be driven to face the side where the display screen 200 is located.

Generally, the axis of rotation of the first support 300 relative to the housing 100 is a first axis, and the axis of rotation of the second support 400 relative to the first support 300 is a second axis, and the first axis may be parallel to the second axis, which is more beneficial to achieve more regular movement of the second support 400 and the first support 300.

In order to more flexibly adjust the working angle during the specific movement, the axis of the driven device 500 rotating relative to the second bracket 400 may be a third axis.
