Description

Terminal device and control method of terminal device

Technical Field

The present invention relates to the field of communications devices, and in particular, to a terminal device and a control method for the terminal device.

Background

With the improvement of user requirements, the performance of the terminal device is continuously optimized, wherein the more prominent expression is as follows: the screen occupation of terminal devices is getting larger and larger. In order to increase the screen occupation ratio of the terminal device, the functional devices (such as a camera and a flash lamp) originally arranged on the frame of the terminal device are increasingly in a lifting structure. When the functional device is required to work, the driving mechanism can drive the functional device to extend out of the shell from the inner cavity of the shell of the terminal equipment; when the functional device finishes working, the driving mechanism can drive the functional device to move into the inner cavity of the shell, so that the functional device is hidden. The structure of the functional device can undoubtedly avoid occupying the board space of the terminal equipment, and further can increase the area of the screen as much as possible on the premise of determining the size of the whole terminal equipment, so as to achieve the purpose of increasing the screen occupation ratio.

Along with the performance of the functional device is better and the functions are more and more, the functional device can generate more heat in the working process, but as the functional device is used as a movable module, a more stable heat dissipation path cannot be formed with other structures of the terminal equipment, and the heat dissipation of the functional device is not facilitated. This tends to cause the temperature of the functional device to rise rapidly during operation, and when the temperature of the functional device exceeds its operating temperature range, the performance of the functional device is affected, and even irreversible damage may be caused in severe cases. Therefore, functional devices capable of lifting in the current terminal equipment cannot be timely dissipated due to heat, and the problem of easy damage is caused. Of course, the same problem also exists with other functional devices in the terminal equipment, not limited to the functional device capable of ascending and descending.

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. 1 to fig. 3, a terminal device is disclosed in an embodiment of the present invention, and the disclosed terminal device includes a housing 100, a functional device 200, and a control circuit 300.

The housing 100 is a base member of the terminal device, and the housing 100 provides a mounting base for other constituent members of the terminal device.

The functional device 200 and the control circuit 300 are provided to the housing 100. The functional device 200 is capable of performing a certain function and generates heat during operation. In an embodiment of the present invention, the functional device 200 may include at least one of a camera, a flash, a microphone, an ambient light sensor, and a fingerprint sensor. Of course, the functional device 200 may also include other types of electronic devices, and the specific type of the functional device 200 is not limited by the embodiments of the present invention.

The control circuit 300 includes a control module 310, a stationary electrical connector 320, and a movable electrical connector 330 connected in series, the control module 310 being connected to the functional device 200, the control module 310 being capable of controlling the functional device 200 to turn off. Specifically, the control module 310 may be a control chip disposed on a motherboard of the terminal device, for example, the control module 310 is a central processing chip of the terminal device.

The movable electrical connector 330 can be electrically connected to the fixed electrical connector 320 through its own movement, and specifically, in the embodiment of the present invention, the movable electrical connector 330 is made of a shape memory alloy, and the movable electrical connector 330 is connected to the functional device 200, so that heat conduction can occur between the functional device 200 and the movable electrical connector 330. The heat generated by the functional device 200 during the operation process is transferred to the movable electrical connector 330, and then the temperature of the movable electrical connector 330 itself is changed, so that the movable electrical connector 330 is contacted and separated from the fixed electrical connector 320 through the deformation of the movable electrical connector 330, and finally the electrical connection is switched on and off.

When the temperature of the functional device 200 is greater than or equal to the preset temperature value, the movable electrical connector 330 deforms and is communicated with the fixed electrical connector 320, in this case, a circuit formed by the control module 310, the movable electrical connector 330 and the fixed electrical connector 320 is in a closed state, the control module 310 can work, the control module 310 controls the functional device 200 to be closed, and further damage to the functional device 200 due to overhigh temperature can be avoided.

When the temperature of the functional device 200 is lower than the set temperature value, the movable electrical connector 330 deforms to be disconnected from the fixed electrical connector 320, in this case, the circuit formed by the control module 310, the movable electrical connector 330 and the fixed electrical connector 320 is in an open circuit state, the control module 310 cannot control the functional device 200 to be closed, and the functional device 200 can be kept in an open working state.

It should be noted that, in the embodiment of the present invention, the preset temperature value is a critical temperature value at which the movable electrical connector 330 can deform, and the preset temperature value depends on the specific material of the movable electrical connector 330.

When the temperature is lower than the preset temperature value during the operation of the functional device 200, the control circuit 300 is in the open circuit state, and the control module 310 does not control the functional device 200 to be turned off, so that the functional device 200 is kept in the operation state. Therefore, the terminal device disclosed by the embodiment of the invention can avoid the problem of damage caused by overhigh heat accumulation when the functional device 200 works.

In the terminal device disclosed in the embodiment of the present invention, the fixed electrical connector 320 may have various structures, and in an optimal scheme, the fixed electrical connector 320 may be a bent metal sheet, and the bent metal sheet has certain elasticity, so that reliable contact with the movable electrical connector 330 is more easily achieved, and further communication is achieved.

Similarly, the structure of the movable electrical connector 330 can be varied as long as the deformation requirement of the movable electrical connector 330 can be satisfied. In a more preferred scheme, one end of the movable electrical connector 330 may be a fixed connection end, the fixed connection end is connected to the functional device 200, the other end of the movable electrical connector 330 may be a deformed free end, and the deformed free end corresponds to the fixed electrical connector 320, so that the deformed free end may contact or separate from the fixed electrical connector 320 when deformed, as shown in fig. 2 and 3, the movable electrical connector 330 with such a structure is advantageous to deformation due to one end being fixed and the other end being a free end.

During a particular operation, the movable electrical connector 330 needs to be in contact with the functional device 200 to achieve thermal conduction of the functional device 200 to accommodate the deformation. Based on this, in a more preferable scheme, the fixed connection end of the movable electrical connector 330 may be fixed on the functional device 200.

Referring to fig. 1 again, in the terminal device disclosed in the embodiment of the present invention, the functional device 200 may include a device bracket 210, a device body 220, and a circuit board 230, the circuit board 230 may be mounted on the device bracket 210, the device body 220 may be mounted on the circuit board 230, and the fixed electrical connector 320 and the movable electrical connector 330 may be mounted on the circuit board 230, in this case, the fixed electrical connector 320, the movable electrical connector 330, and the functional device 200 are favorable to form an integral module, so as to be conveniently mounted on the housing 100, and meanwhile, the movable electrical connector 330 is located inside the functional device 200, so as to better sense the temperature of the functional device 200 to deform. Specifically, the device body 220 may be soldered to the circuit board 230. The circuit board 230 may be fixed to the device holder 210.

When the functional device 200 is required to work, the driving mechanism drives the functional device 200 to extend out of the shell 100 through the through hole 121; when the functional device 200 is finished, the driving mechanism drives the functional device 200 to retract into the casing 100 through the through hole 121, thereby hiding the functional device 200.
