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 3, an embodiment of the present invention discloses a mobile terminal including a case 100, a driven member 200, a driving source 300, and a driving cord 400.

The housing 100 has a bezel. Generally, the frame defines a through hole 110, the through hole 110 is communicated with the inner cavity of the casing 100, and the through hole 110 is used for the driven member 200 to pass through and enter the casing 100. Of course, the driven member 200 may enter or exit the casing 100 through other passages, and is not limited to the through hole 110 formed in the casing 100.

The driven member 200 is movably disposed in the housing 100 and further enters and exits the housing 100 through the through hole 110, that is, the driven member 200 is movable between a retracted position and an extended position through the through hole 110. In the extended position, at least a portion of the driven member 200 is located outside the housing 100, and the driven member 200 can perform the corresponding function; in the retracted position, the driven member 200 is located within the housing 100, at which time the driven member 200 may not be operational. Such a driven part 200 does not occupy a display area of the mobile terminal, and thus a screen area of the mobile terminal is large. In the embodiment of the present invention, the driven component 200 may include at least one of a camera module, a sensor, a fingerprint identification module, a receiver, and a fill-in light, and may also include other components.

The driving source 300 is disposed in the case 100. Alternatively, the driving source 300 may be fixed to the mounting bracket 500 by welding, bonding, or the like, and the mounting bracket 500 is fixed to the casing 100 by a plurality of screws 600, thereby achieving connection between the driving source 300 and the casing 100. The driving source 300 is provided with a driving shaft 310, and the driving shaft 310 can output a driving force, which can be transmitted to the driven member 200 to achieve the movement of the driven member 200 relative to the housing 100. In an alternative embodiment, the driving source 300 may include a motor and a reduction gear connected to the motor, and the driving shaft 310 may be connected to the reduction gear, which may increase the torque output from the driving shaft 310, thereby more reliably driving the driven member 200.

The driving rope 400 may be a flexible structure wound around the driving shaft 310, and the length direction of the driving rope 400 is the same as the moving direction of the driven member 200. Alternatively, to facilitate driving the driven member 200, the first end 410 and the second end 420 of the driving rope 400 are respectively connected to the driven member 200, i.e., the first end 410 and the second end 420 are connected at different positions of the driven member 200. The distance between the first end 410 and the perforation 110 is smaller than the distance between the second end 420 and the perforation 110, i.e. the first end 410 is closer to the perforation 110 than the second end 420. When the driving source 300 is in an operating state, the driving shaft 310 rotates to pull the driving rope 400, and the driving rope 400 drives the driven member 200 to move, in the process, the contact position of the driving rope 400 and the driving shaft 310 changes, so that the position of the driving shaft 310 relative to the driving rope 400 changes. That is, the driving shaft 310 can drive the driven member 200 to extend out of the casing 100 or retract into the casing 100 from the through hole 110 through the driving rope 400. In a specific embodiment, the forward rotation of the driving source 300 can achieve the purpose of extending the driven member 200 out of the housing 100, and the reverse rotation of the driving source 300 can achieve the purpose of retracting the driven member 200 into the housing 100.

When the structure is adopted, the driven part 200 can be driven only by the driving source 300 and the driving rope 400, and a complex transmission mechanism is not required, so that the structure of the mobile terminal is simpler, the assembly operation of the mobile terminal is simpler, the cost is lower, and the working reliability is higher. In addition, the space occupied by the driving source 300 and the driving rope 400 is smaller, thereby being more beneficial to the design of other structures in the mobile terminal; the transmission path between the driving source 300 and the driven member 200 is shorter and the transmission efficiency is higher, so that the driven member 200 can be more rapidly extended out of the housing 100 and retracted into the housing 100.

In a specific embodiment, a first driving tooth may be disposed on the driving shaft 310, and a second driving tooth is correspondingly disposed on the driving rope 400, and the first driving tooth and the second driving tooth are engaged with each other, so as to realize power transmission between the driving shaft 310 and the driving rope 400. However, providing the first drive tooth on the drive shaft 310 and the second drive tooth on the drive cord 400 complicates the manufacturing process of the drive shaft 310 and the drive cord 400, and thus, to solve this problem, the drive shaft 310 and the drive cord 400 may transmit force by means of friction fit. Specifically, the surface of the driving shaft 310 has a first friction surface, and the surface of the driving rope 400 contacting the driving shaft 310 is a second friction surface, and the first friction surface is matched with the second friction surface. When the driving shaft 310 rotates, the first friction surface is attached to the second friction surface, so that a friction force is formed between the first friction surface and the second friction surface, and the driving rope 400 is driven to move. This structure allows the surface of the driving shaft 310 and the driving rope 400 to transmit the acting force, and thus, it is not necessary to provide another structure, thereby simplifying the manufacturing process of the driving shaft 310 and the driving rope 400.

Further, the driving rope 400 may be provided as an elastic rope. At this time, the driving rope 400 has elasticity, and after the driving rope 400 is wound on the driving shaft 310 and connected to the driven member 200, the driving rope 400 can be properly stretched so that the driving rope 400 and the driving shaft 310 are more closely attached together, thereby making the force transmission between the two more reliable. In addition, such a driving rope 400 also has an impact absorbing function, and when the driven member 200 or the driving source 300 is subjected to an impact, the driving rope 400 can absorb the impact, thereby preventing damage to the driven member 200 and the driving source 300.

To prevent the driving rope 400 from being separated from the driving shaft 310, a positioning groove 311 may be provided on the driving shaft 310, and the driving rope 400 is wound at the positioning groove 311. The positioning groove 311 may restrict the movement of the driving rope 400 in the axial direction of the driving shaft 310 such that the portion of the driving rope 400 wound around the driving shaft 310 is always positioned at the positioning groove 311. Alternatively, the positioning slot 311 may be provided as an annular groove to increase the fitting area of the driving rope 400 and the positioning slot 311, thereby optimizing the limit effect.

The number of turns of the portion of the drive cord 400 wound on the drive shaft 310 may be one, two or more turns. However, as the number of turns of the portion increases, the contact area between the driving cord 400 and the driving shaft 310 increases, so that the driving shaft 310 needs to output a greater driving force to pull the driving cord 400, resulting in an increase in power consumption of the mobile terminal. Based on this, it is preferable that the driving rope 400 is wound around the driving shaft 310 with one turn, so that the driving rope 400 can be reliably pulled and the power consumption of the mobile terminal can be controlled within a reasonable range.

The specific arrangement of the first end 410 and the second end 420 of the driving rope 400 can be flexibly selected, but in order to more effectively drive the driven member 200 to move, the first end 410 and the second end 420 can be arranged along the moving direction of the driven member 200. At this time, the force applied by the driving rope 400 to the driven member 200 is parallel to the moving direction of the driven member 200, and thus the driven member 200 can be driven to move more efficiently.

In further embodiments, the axial direction of the driving shaft 310 may be perpendicular to the moving direction of the driven member 200. At this time, the driving shaft 310 is substantially perpendicular to the driving rope 400, i.e., the axial direction of the driving shaft 310 is perpendicular to the line connecting the first end 410 and the second end 420. Thus arranged, the driving force output from the driving shaft 310 is perpendicular to the moving direction of the driving rope 400, and thus the driving shaft 310 can more effectively pull the driving rope 400.

Alternatively, the first end 410 and the second end 420 of the driving rope 400 may be fixed at different positions of the driven member 200 by means of bonding, but this connection is less reliable. Therefore, in another embodiment, the driven component 200 may be provided with a first connecting column 210 and a second connecting column 220, the first connecting column 210 and the second connecting column 220 are arranged at intervals in the moving direction of the driven component 200, both the first end 410 and the second end 420 may be provided with a connecting ring, the first end 410 is sleeved on the first connecting column 210 through the connecting ring, and the second end 420 is sleeved on the second connecting column 220 through the connecting ring. When such a connection method is adopted, the driving rope 400 and the driven member 200 are not easily separated, so that the connection reliability between the driving rope and the driven member is higher. Further, the first connection column 210 and the second connection column 220 may extend in the thickness direction of the mobile terminal, thereby improving the connection reliability of both ends of the driving rope 400 and the driven member 200.

In order to appropriately increase the contact area between the driving rope 400 and the driving shaft 310, the cross-sectional shape of the driving rope 400 may be set to be rectangular such that the driving shaft 310 is in contact with one of the planes of the driving rope 400. Further, the cross-sectional shape of the driving rope 400 may be rectangular, and the driving shaft 310 is in contact with a wider plane of the driving rope 400, so that the contact area between the driving rope 400 and the driving shaft 310 is larger, and the driving rope 400 is prevented from being twisted when moving, thereby improving the stability of the driving rope 400 and preventing the driving rope 400 from being broken.

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. Various modifications and alterations to this invention will become apparent to those skilled in the art.
