Detailed ways

In order to make the objectives, technical solutions, and advantages of the present disclosure clearer, the technical solutions of the present disclosure will be described clearly and completely in conjunction with specific embodiments of the present disclosure and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

The technical solutions disclosed in each embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

As shown in FIGS. 1 to 8, an embodiment of the present disclosure discloses a mobile terminal, which includes a housing 100, a first display screen 200, a second display screen 300, and a driving mechanism.

The housing 100 has a first side and a second side facing away from each other. The first side may be the front side of the mobile terminal, and the second side may be the back side of the mobile terminal. Of course, the mobile terminal may not be divided into front and back sides. An opening 110 is defined in the housing 100, and the opening 110 allows the second display screen 300 to enter and exit the housing 100. The opening 110 may be specifically opened on the middle frame of the housing 100.

The first display screen 200 is disposed on the housing 100, and may be specifically disposed on the first surface. The first display screen 200 may be the main screen of the mobile terminal. The second display screen 300 may be provided in the housing 100, and the second display screen 300 may be a secondary screen of the mobile terminal. The second display screen 300 can move relative to the housing 100, so the second display screen 300 has a first state and a second state, and it can be switched between the first state and the second state. Wherein, in the first state, the second display screen 300 is located in the housing 100, at this time the second display screen 300 is located between the first surface and the second surface; in the second state, the second display screen 300 is at least partially Located outside the housing 100. That is to say, in the second state, the second display screen 300 may all be located outside the housing 100, or only a part of it may be located outside the housing 100, and the second display screen 300 extends out of the housing 100 in the second state. The range can be determined according to the actual needs of users, this article does not limit it.

The driving mechanism is arranged in the housing 100 and is connected to the second display screen 300 to drive the second display screen 300 to switch between the first state and the second state. The driving mechanism may specifically be a telescopic cylinder, a linear motor, and the like.

When the user needs to expand the display area, the driving mechanism can drive the second display screen 300 to move so that it extends out of the housing 100. At this time, the first display screen 200 and the second display screen 300 can jointly display the content that needs to be displayed; When there is no need to expand the display area, the driving mechanism can drive the second display screen 300 to move in the reverse direction to retract it into the housing 100. When the second display screen 300 is retracted into the housing 100, the housing 100 can protect the second display screen 300 even if the mobile terminal is dropped, so that the second display screen 300 is not prone to damage, and the service life of the mobile terminal varies. The extension. Further, a detection structure and a control structure can be provided in the mobile terminal. If the mobile terminal falls when the second display screen 300 is in the second state, the detection structure can identify the fall, and the control structure can control the driving mechanism to drive the second display. The screen 300 is retracted into the housing 100 to protect the second display screen 300.

Specifically, the first display screen 200 can play videos, game interfaces, etc., and the second display screen 300 can display notification messages, or display web pages, etc., so that the user can view related content while watching videos and playing games. Of course, the first display screen 200 and the second display screen 300 can also display different contents of the same complete interface together.

In addition, the above mobile terminal basically has no special requirements on the structure of the back cover 120 of the housing 100, so the structure design of the back cover 120 is more flexible. For example, the back cover 120 can be set in a curved shape to better suit the user's holding posture. .

In order to facilitate the connection between the second display screen 300 and the driving mechanism, the second display screen 300 may include a display screen support 310 and a screen body 320. Optionally, the display screen bracket 310 may be slidably connected to the housing 100 through a sliding mechanism (not shown in the figure), so as to improve the movement accuracy of the display screen bracket 310. The display screen bracket 310 has an installation surface, and the screen body 320 is disposed on the installation surface. The mounting surface can be located on the same side of the mobile terminal as the first surface, or on the same side of the mobile terminal as the second surface. However, in order to facilitate the combined use of the second display screen 300 and the first display screen 200, the present disclosure implements For example, the optional mounting surface and the first surface are located on the same side of the mobile terminal, that is, the mounting surface and the first display screen 200 are both facing the same side of the mobile terminal. This structure is more in line with the user's usage habits, thereby obtaining a better user experience. In order to optimize the aesthetics of the mobile terminal, the sliding mechanism can be arranged on the side surface of the display screen bracket 310 away from the installation surface. When the second display screen 300 is in the second state, the user can hardly see the sliding mechanism. The driving mechanism may be drivingly connected with the display screen bracket 310 to drive the second display screen 300 to switch between the first state and the second state.

In an optional embodiment, in order to simplify the structure of the driving mechanism, the driving mechanism may include a driving source 410 and a transmission component. The transmission component is connected with the driving source 410, and the transmission component is connected with the display screen bracket 310 to drive the display screen bracket 310 to move. The driving source 410 here may specifically be a motor, and the transmission components may include components such as a lead screw and a lead screw cover. The motor can drive the lead screw to rotate, and the lead screw drives the lead screw cover to move, thereby achieving the purpose of moving the display screen bracket 310.

In order to reduce the space occupied by the transmission component, the transmission component in the embodiment of the present disclosure may include a gear 420 which is connected to the driving source 410. A rack 330 is provided on the side surface of the display screen bracket 310 away from the mounting surface. The extending direction of the bar 330 is parallel to the moving direction of the display screen bracket 310. The gear 420 meshes with the rack 330 to drive the display screen bracket 310 to move. The gear 420 can be installed on the output shaft of the driving source 410, and the gear 420 directly meshes with the rack 330 to transmit the power output by the driving source 410 to the rack 330, so that the rack 330 moves, and then drives the display bracket 310 mobile. This kind of transmission component contains a small number of components, and the movement space required by the transmission component is smaller, so it occupies a smaller space to facilitate the arrangement of other components in the mobile terminal.

Only one gear 420 and rack 330 may be provided. In this case, the rack 330 may be arranged at the center of the display screen bracket 310 to achieve stable movement of the display screen bracket 310. However, this structure is prone to problems such as deflection of the display support 310 and insufficient power applied to the display support 310. In order to solve these problems, both the gear 420 and the rack 330 may be provided as at least two, the racks 330 are arranged at intervals, and the gears 420 and the racks 330 mesh in a one-to-one correspondence. This configuration can increase the force position of the display screen bracket 310. On the one hand, the driving force can be increased, and on the other hand, the driving force can be evenly applied to the display screen bracket 310, so that the display screen bracket 310 moves more smoothly.

Based on considerations such as installation space and cost, the number of gears 420 and racks 330 described above should not be too large. In the embodiment of the present disclosure, the display screen bracket 310 has a first edge 311 and a second edge 312. The first edge 311 and the second edge 312 are respectively located at two ends of the display screen bracket 310 along the first direction. It is perpendicular to the moving direction of the second display screen 300. In order to effectively control the number of racks 330 and gears 420, racks 330 may be provided on the first edge 311 and the second edge 312, respectively. Optionally, the rack 330 may be provided only on the first edge 311 and the second edge 312 respectively, and the rack 330 may not be provided at other positions. This structure basically does not adversely affect the movement stability of the display screen bracket 310.

When the gear 420 and the rack 330 are provided in multiples, the driving source 410 may be provided with only one or multiple. If only one drive source 410 drives multiple gears 420 to rotate, on the one hand, the size of the drive source 410 itself will be too large. On the other hand, additional transmission structures need to be added to drive multiple gears 420 to rotate at the same time. This brings difficulties to the arrangement of other parts in the mobile terminal. For this reason, the number of driving sources 410 may be at least two, and each driving source 410 drives each gear 420 to rotate, and each gear 420 drives each rack 330 to move correspondingly. Since a single drive source 410 only needs to drive one gear 420 to rotate, the size of the drive source 410 can be set to be relatively small, and each drive source 410 is relatively independent, which can prevent the drive mechanism from occupying the layout space of other components.

Optionally, the output shaft of the driving source 410 may be perpendicular to the extending direction of the rack 330. At this time, the driving source 410 may be arranged next to the middle frame of the housing 100 to make the distance from the central area of the housing 100 farther, so as to facilitate the arrangement of structures such as a lifting camera inside the housing 100.

In order to minimize the space occupied by the second display screen 300, a groove may be provided on the surface of the display support 310 away from the mounting surface, and the rack 330 is at least partially located in the groove. The rack 330 can make full use of the space occupied by the display bracket 310, so that the additional space occupied by the rack 330 is smaller, or even does not occupy additional space, so the thickness of the mobile terminal is smaller.

When the mobile terminal has a rectangular structure as a whole, the mobile terminal has a length direction (that is, the X direction shown in FIG. 5). At this time, the opening 110 opened on the housing 100 may be configured as a bar-shaped opening extending along the length of the mobile terminal, and the second display screen 300 is in the first state and the second state through the bar-shaped opening. Switch between. In other words, the strip-shaped opening is provided on the long side of the housing 100, so the size of the strip-shaped opening can be set to be relatively large, and then allow the larger second display screen 300 to enter and exit the housing 100, so as to better satisfy users The demand for larger screens. Of course, if the mobile terminal has a square structure, the position of the opening 110 can be selected according to the actual situation to meet the needs of the user.

In the embodiment of the present disclosure, the size of the second display screen 300 can be made smaller than the size of the first display screen 200 in the above-mentioned length direction. When the user holds the mobile terminal horizontally, the user's hand can be held in the housing 100. The positions on both sides of the second display screen 300, thereby obtaining a better user experience.

The mobile terminal disclosed in the embodiments of the present disclosure may be a smart phone, a tablet computer, an e-book reader or a wearable device. Of course, the mobile terminal may also be other devices, which is not limited in the embodiments of the present disclosure.
