As mobile terminals (e.g., mobile phones and tablet computers) have more and more functions, more and more functional devices are configured on the mobile terminals, such as cameras, face recognition modules, ambient light sensing modules, and the like, which brings great challenges to the assembly of the mobile terminals. Along with the improvement of the appearance requirement of a user on the mobile terminal, the user is more and more favored by the mobile terminal with a large screen occupation ratio, and on the premise that the size of the whole mobile terminal is determined, the larger and larger screen occupation ratio can cause that functional devices arranged on the board surface of the mobile terminal in the past do not have enough installation space.

In order to increase the screen occupation ratio of the mobile terminal, the camera of the current mobile terminal is a lifting camera, and the lifting camera is driven by a driving mechanism arranged in a shell of the mobile terminal, so that the mobile terminal can enter and exit the shell. When a user needs to shoot, the driving mechanism is controlled to drive the lifting type camera to extend out of the shell, and then shooting is carried out. After the shooting is finished, the driving mechanism is controlled to drive the lifting type camera to retract into the shell, and the purpose of hiding the camera is achieved. The mobile terminal of above-mentioned structure can avoid the camera to its face occupation of space, and then can reduce the frame width of casing, and the frame width reduces then can make the area increase of display screen, and the screen that finally can increase mobile terminal accounts for than.

In present mobile terminal, actuating mechanism includes the motor, and the motor can lead to mobile terminal's cost higher, adopts motor drive to need dispose comparatively complicated drive mechanism moreover, just can realize the drive to over-and-under type camera, and this can lead to mobile terminal's structure comparatively complicated undoubtedly.

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 16, an embodiment of the invention discloses a mobile terminal, which includes a housing 100, a telescopic module 200, an elastic driving element 310 and a linkage limiting element 320.

The housing 100 has a bezel 110. In general, the frame 110 defines an opening 111, the opening 111 is communicated with the inner cavity 120 of the housing 100, and the opening 111 is used for the expansion module 200 to pass through and enter the housing 100. Of course, the telescopic module 200 can also enter and exit the housing 100 through other passages, and is not limited to the opening 111 formed on the frame 110.

The telescopic module 200 is movably disposed in the housing 100 to enter and exit the housing 100 through the opening 111, that is, the telescopic module 200 is movable between a retracted position and an extended position through the opening 111. In the extended position, at least a portion of the retractable module 200 is located outside the housing 100, and the retractable module 200 can perform a corresponding function; in the retracted position, the telescoping module 200 is within the housing 100, at which time the telescoping module 200 may not be operational. The telescopic module 200 does not occupy the display area of the mobile terminal, so the screen occupation ratio of the mobile terminal is large. In the embodiment of the present invention, the retractable module 200 may include at least one of a camera, a sensor, a fingerprint recognition module, a receiver, and a fill-in light. The retractable module 200 has a first position-limiting portion 210 and a first transmission portion 220.

The elastic driving member 310 is installed in the housing 100 and connected to the expansion module 200, so that the elastic driving member 310 can apply an ejection force to the expansion module 200, and the expansion module 200 can extend out of the housing 100 under the ejection force. In other words, the elastic driving member 310 always drives the telescopic module 200 to move to the extended position. The linkage limiting member 320 is rotatably installed in the housing 100, and specifically, the linkage limiting member 320 may be disposed in the housing 100 through a rotating shaft 330, and an extending direction of the rotating shaft 330 is substantially parallel to a thickness direction of the mobile terminal. The linkage limiting member 320 is provided with a second limiting portion 321 and a linkage portion 322, the second limiting portion 321 can be in positioning fit with the first limiting portion 210, so that the telescopic module 200 cannot extend out of the housing 100 even if being subjected to an ejection force, and the linkage portion 322 can be in contact with the first transmission portion 220 and is subjected to an acting force applied by the first transmission portion 220, so as to drive the linkage limiting member 320 to rotate. When the linkage limiting member 320 rotates, the relative position and the matching state of the first limiting portion 210 and the second limiting portion 321 change, so that the expansion module 200 can move between the extended position and the retracted position.

As shown in fig. 8, when the retractable module 200 is in the retracted position, the first position-limiting portion 210 and the second position-limiting portion 321 are positioned and engaged to block the retractable module 200 from moving to the extended position. The first transmission part 220 and the linkage part 322 may be in contact or have a small gap. As shown in fig. 9, when a user needs to use the retractable module 200, the retractable module 200 can be pressed to move the retractable module 200, then the first transmission portion 220 presses the linkage portion 322, and the linkage limiting member 320 is driven by the linkage portion 322 to rotate in the first direction until the first limiting portion 210 and the second limiting portion 321 are switched from the state of positioning fit to the state of being separated from each other, i.e., the state shown in fig. 10, and at this time, the second limiting portion 321 is located on one side of the first limiting portion 210, which no longer limits the retractable module 200, so that the retractable module 200 can extend out of the housing 100 under the action of the elastic driving member 310, i.e., the state shown in fig. 11. After the telescopic module 200 is extended, the linkage limiting member 320 can move reversely under the action of a spring and the like to return to the initial state, and at this time, the second limiting portion 321 is located at the other side of the first limiting portion 210, that is, the state shown in fig. 13, so that the telescopic module 200 can be retracted into the housing 100.

As shown in fig. 14, after the telescopic module 200 is used, the user can press the telescopic module 200 again to move the telescopic module 200. Since the linkage stopper 320 is reset, the linkage portion 322 is located in the moving track of the first transmission portion 220. As shown in fig. 15, when the first transmission portion 220 contacts the linking portion 322 again, the telescopic module 200 can drive the linking limiting member 320 to rotate along the first direction through the linking portion 322 along with the continuous pressing of the user until the first limiting portion 210 and the second limiting portion 321 are in positioning engagement again, that is, the state shown in fig. 16 finally stays in the state shown in fig. 8. At this time, even if the flexible driving element 310 is applied with a force, the retractable module 200 is restricted by the second limiting portion 321 and cannot move, so that the retractable module 200 can be maintained at the retracted position and cannot move to the extended position.

As can be seen, the extension and retraction of the telescopic module 200 are implemented without a motor and a transmission mechanism with a complicated structure, so that the cost of the mobile terminal disclosed in the embodiment of the present invention is reduced, and the structure is simpler.

As mentioned above, the resetting of the linkage limiting member 320 can be realized by a spring when the telescopic module 200 extends out of the housing 100, but the structure of the spring and the elastic driving member 310 is relatively high, and the telescopic module 200 is liable to fail to extend out of the housing 100. Therefore, in the embodiment of the present invention, the telescopic module 200 is further provided with a second transmission portion 230, and the first transmission portion 220 is located between the opening 111 and the second transmission portion 230, i.e. the first transmission portion 220 is closer to the opening 111 than the second transmission portion 230. As shown in fig. 11 and 12, in the process that the telescopic module 200 extends out of the housing 100 through the opening 111, as the telescopic module 200 moves, the second transmission portion 230 gradually approaches the linkage portion 322, when the second transmission portion 230 contacts the linkage portion 322, as the telescopic module 200 continuously moves, the second transmission portion 230 can drive the linkage portion 322 to move in a direction approaching the opening 111, and further, the linkage portion 322 drives the linkage limiting member 320 to rotate in the second direction, so that when the telescopic module 200 is at the extended position, the second limiting portion 321 is located outside the motion trajectory of the first limiting portion 210, and the linkage portion 322 is located on the motion trajectory of the first transmission portion 220, so that when the telescopic module 200 moves to the retracted position, the first transmission portion 220 can drive the linkage limiting member 320 to rotate through the linkage portion 322. After the arrangement, the linkage limiting part 320 can be driven to reset in the process that the telescopic module 200 extends out of the shell 100, and the reliability is higher. It should be noted that the first direction is opposite to the second direction described above.

In a specific embodiment, in the moving direction of the telescopic module 200, the first transmission portion 220 and the second transmission portion 230 may not be aligned, but since the positions where the two are engaged with the linkage portion 322 are substantially the same, if the two are not aligned, at least one of the two needs to be set larger to ensure that the two can contact the linkage portion 322 successively, which results in a larger space occupied by the first transmission portion 220 and the second transmission portion 230. For this reason, the first transmission part 220 and the second transmission part 230 may be arranged along the moving direction of the telescopic module 200, so that the sizes of the two parts are set to be smaller as much as possible, and it is more convenient to arrange the components in the mobile terminal.

In order to simplify the structure of the linkage limiting member 320 and set the size of the linkage limiting member 320 to be smaller, the linkage limiting member 320 in the embodiment of the present invention specifically includes a cylindrical portion 323 and a protruding portion 324. Wherein: the middle of the cylindrical portion 323 may be opened to facilitate the connection of the cylindrical portion 323 with the rotating shaft 330, thereby achieving the installation of the linkage stopper 320 in the housing 100; the protrusion 324 may extend in a direction perpendicular to a thickness direction of the mobile terminal and protrude with respect to the cylindrical portion 323, and the protrusion 324 and the cylindrical portion 323 may be connected to form a cam structure; the second limiting portion 321 is disposed on the protrusion portion 324; the interlocking portion 322 is provided on the cylindrical portion 323.

Further, the first position-limiting portion 210 and the first transmission portion 220 may be both configured to protrude from the boss structure of the telescopic module, so that the second position-limiting portion 321 and the linkage portion 322 are both protruding from the boss structure of the linkage position-limiting member 320. Of course, the cross-sectional shape of the four can be flexibly selected, and can be, for example, rectangular, circular, oval, triangular, or other shapes.

As shown in fig. 9 to 11, a user presses the retractable module 200, such that the first transmission portion 220 presses the linkage portion 322, and further the first limiting portion 210 is separated from the second limiting portion 321, and then the retractable module 200 extends out of the housing 100 under the action of the elastic driving member 310, in which process the first transmission portion 220 needs to pass over the second limiting portion 321. In order to prevent the first transmission part 220 from interfering with the second stopper 321, the protruding height of the second stopper 321 may be smaller than the protruding height of the linking part 322. It should be noted that the direction of the protrusion height is substantially parallel to the thickness direction of the mobile terminal.

Similarly, in the above process, the first transmission part 220 needs to go beyond the second limiting part 321, so in order to prevent the first transmission part 220 from interfering with the second limiting part 321, the protruding height of the first limiting part 210 can be made larger than the protruding height of the first transmission part 220, so as to reduce the protruding height of the first transmission part 220 as much as possible, and reduce the probability of interference. The specific protruding heights of the first limiting portion 210, the first transmission portion 220, the second limiting portion 321, and the linkage portion 322 may be determined according to the overall size of the mobile terminal, the size of the telescopic module 200, the motion track, and other factors, which is not limited herein.

In an alternative embodiment, an arc concave surface 211 recessed away from the opening is disposed on a surface of the first position-limiting portion 210 facing the opening 111, and a V-shaped surface 212 protruding away from the opening is disposed on a surface of the first position-limiting portion 210 facing away from the opening 111. The arc concave surface 211 can increase the contact area between the first limiting part 210 and the second limiting part 321 as much as possible, so that the limiting effect is improved; the size of the first limiting portion 210 on the side away from the opening 111 can be reduced as much as possible by adopting the V-shaped surface 212, so that the space occupied by the first limiting portion 210 is smaller, the arrangement of parts in the mobile terminal is facilitated, and meanwhile, the first limiting portion 210 can be prevented from interfering with other parts.

The above-mentioned linkage limiting member 320 can be directly installed on the casing 100, but there are many parts to be arranged in the casing 100, and this arrangement mode is often limited by a relatively large amount and cannot be realized. For this purpose, the mobile terminal further includes a mounting bracket 400, the mounting bracket 400 is connected to the housing 100, an accommodating space is formed between the mounting bracket 400 and the housing 100, the linkage limiting member 320 is rotatably mounted on the mounting bracket 400, and the linkage limiting member 320 is located in the accommodating space. Specifically, the mounting bracket 400 may be secured to the housing 100 by a plurality of fasteners 500. In addition, when the linkage limiting member 320 is disposed in the housing 100 through the rotating shaft 330, the rotating shaft 330 may be a screw, which is connected to the mounting bracket 400, and the linkage limiting member 320 may rotate around the rotating shaft 330.

In the embodiment of the present invention, the elastic driving member 310 may be an elastic member such as a compression spring, a tension spring, a torsion spring, or other structures capable of driving the retractable module 200 to extend. In order to facilitate the arrangement of the elastic driving member 310 and simplify the structure of the elastic driving member 310, the embodiment of the invention provides the elastic driving member 310 as a torsion spring. At this time, the expansion module 200 is further provided with a torsion spring connecting portion 240, the housing 100 is provided with a mounting post 140, the torsion spring is sleeved on the mounting post 140, one end of the torsion spring is connected with the housing 100, the other end of the torsion spring is connected with the torsion spring connecting portion 240, and a spiral axis of the torsion spring may be substantially parallel to a thickness direction of the mobile terminal.

As described above, the movement of the telescopic module 200 is performed manually by a user, in order to prevent the user from pressing the telescopic module 200 excessively to cause the telescopic module 200 to collide with other components, the housing 100 is provided with the stop portion 130, in the retracted position, the stop portion 130 is located on one side of the telescopic module 200 away from the opening 111 and is spaced from the telescopic module 200 by a predetermined distance, the predetermined distance can allow the user to press the telescopic module 200 when the user needs to use the telescopic module 200, and the telescopic module is further convenient to drive the linkage limiting member 320 to rotate through the linkage portion 322. When the telescopic module 200 moves, once the telescopic module 200 contacts the stop portion 130, the stop portion 130 restricts the telescopic module 200, so that the telescopic module 200 cannot move continuously and stays at a predetermined position.

When the telescopic module 200 is provided with the second transmission part 230, the stop part 130 and the second transmission part 230 may be arranged along the moving direction of the telescopic module 200, i.e., aligned in the direction. In addition, the second transmission part 230 may be disposed at an edge of the telescopic module 200 away from the opening 111, and when the telescopic module 200 contacts the stopper 130, the second transmission part 230 contacts the stopper 130, so that a larger contact area may be formed therebetween, thereby more reliably limiting the position of the telescopic module 200. Specifically, the stop portion 130 and the second transmission portion 230 may both adopt a boss structure.

The mobile terminal 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 mobile terminal 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.
