technical field

The present invention relates to the technical field of communication equipment, and in particular, to a temperature control module and terminal equipment.

Background technique

In order to increase the screen ratio of terminal devices, more and more terminal devices currently use cameras that can be raised and lowered. When the camera needs to shoot, the camera can be extended out of the casing of the terminal device, so that the user can shoot; when the shooting is completed, the camera can be retracted into the casing of the terminal device, so as to realize hiding in the casing . As users have higher and higher demands for photographing effects, photographing quality, and photographing functions, the current terminal equipment can still rotate when the camera extends out of the casing, thereby enabling multi-angle photographing, tracking video and other functions. need.

In the specific working process, when rotating and shooting for a long time, the motor that drives the camera to rotate will have a large heating problem. When the motor or the control module that controls the motor is abnormal, the camera is more likely to be stuck and cannot be retracted into the casing of the terminal device, thereby causing the user to be unable to use it normally. At the same time, the driving motor that drives the movement of the camera will generate heat for a long time, which is more likely to be damaged or cause serious heating of the surface of the terminal device. Of course, other devices in the terminal device also have serious heat generation problems during the working process.

SUMMARY OF THE INVENTION

The invention discloses a temperature control module and a terminal device, so as to solve the problem of serious heat generation in the current terminal device during operation.

In order to solve the above problems, the present invention adopts the following technical solutions:

The temperature control module includes a first magnetic part, a magnetic attraction part, a second magnetic part and a device control module. The first magnetic part is connected to a controlled device of the terminal device. A thermally conductive connection, the device control module is electrically connected to the magnetic attraction, wherein:

When the temperature of the first magnetic member is greater than the first preset temperature, the second magnetic member is in adsorption contact with the magnetic attraction member, and the device control module controls the controlled device to enter the first state; When the temperature of the first magnetic member is lower than the first preset temperature, the first magnetic member is in adsorption contact with the magnetic attraction member, and the magnetic attraction member is separated from the second magnetic member, and the device The control module controls the controlled device to enter the second state.

A terminal device includes a controlled device and the above-mentioned temperature control module.

The technical scheme adopted in the present invention can achieve the following beneficial effects:

During the working process of the temperature control module disclosed in the present invention, since the first magnetic member is thermally connected to the controlled device, as the temperature of the controlled device increases, the temperature of the first magnetic member will also rise. When the temperature is higher than the first preset temperature, the magnetism of the first magnetic member will weaken or even disappear. A magnetic component is separated. In this case, the device control module can control the controlled device to enter the first state. When the temperature of the controlled device is low, the temperature of the first magnetic member is also low. When the temperature of the first magnetic member is lower than the first preset temperature, because the first magnetic member has strong magnetism, the attraction force to the magnetic attraction member is low. It is also larger, so that the magnetic attraction piece is separated from the second magnetic piece, and at the same time, the magnetic attraction piece is in contact with the first magnetic piece. In this case, the device control module controls the controlled device to enter the second state.

Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The technical solutions disclosed by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to FIGS. 1-3 , an embodiment of the present invention discloses a temperature control module 100 , and the disclosed temperature control module 100 can be applied to a terminal device.

The first magnetic member 110 is thermally connected to the controlled device. Specifically, the first magnetic member 110 may be bonded and fixed to the controlled device through thermally conductive glue. During the operation of the controlled device, the heat generated by the controlled device will increase the temperature of the first magnetic member 110 . The first magnetic member 110 is a magnetic member. Since the magnetism is affected by the temperature, the magnetism of the first magnetic member 110 will be weakened along with the increase of the temperature. The first magnetic member 110 and the magnetic attraction member 120 can be magnetically attracted to each other.

The second magnetic member 130 is also a magnetic member. In the embodiment of the present invention, the second magnetic member 130 is also magnetically attracted to the magnetic attraction member 120 .

When the temperature of the first magnetic member 110 is greater than the first preset temperature, the magnetism of the first magnetic member 110 is weakened or even disappears, and the second magnetic member 130 is in adsorption contact with the magnetic attraction member 120 . In this case, the device control module 160 The controlled device is controlled to enter the first state, and the controlled device entering the first state may mean that the controlled device is turned off, or it may mean that the controlled device is in a low-energy working state, such as low-speed operation.

When the temperature of the first magnetic member 110 is lower than the first preset temperature, the first magnetic member 110 is in adsorption contact with the magnetic attraction member 120, and the magnetic attraction member 120 is separated from the second magnetic member 130. In this case, the device control module 160 controls the controlled device to enter the second state. Entering the controlled device into the second state may mean that the controlled device is turned on.

When the temperature of the first magnetic member 110 is greater than the first preset temperature, the magnetism of the first magnetic member 110 will weaken or even disappear. The magnetism of the second magnetic member 130 attracts, so as to contact the second magnetic member 130 and separate from the first magnetic member 110 . In this case, the device control module 160 can control the controlled device to enter the first state.

When the temperature of the controlled device is low, the temperature of the first magnetic member 110 is also low. When the temperature of the first magnetic member 110 is lower than the first preset temperature, since the first magnetic member 110 has strong magnetism, the magnetic attraction The attraction force of the magnetic element 120 is also larger, so that the magnetic attraction element 120 is separated from the second magnetic element 130, and at the same time, the magnetic attraction element 120 is in contact with the first magnetic element 110.
