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.
Referring to fig. 1 to 3, an embodiment of the invention discloses a temperature control module 100, and the disclosed temperature control module 100 can be applied to a terminal device. The terminal device involved includes a controlled device, and the temperature control module 100 can be used for controlling the controlled device. The disclosed temperature control module 100 includes a first magnetic member 110, a magnetically attractive member 120, a second magnetic member 130, and a device control module 160.
The first magnetic member 110 is thermally connected to the controlled device. Specifically, the first magnetic element 110 may be fixed to the controlled device by bonding with a thermal conductive adhesive. During the operation of the controlled device, the temperature of the first magnetic member 110 is increased by the heat generated by the controlled device. The first magnetic member 110 is a magnetic member, and the magnetism is affected by temperature, so that the magnetism of the first magnetic member 110 is weakened along with the increase of the temperature. The first magnetic member 110 and the magnetic member 120 are magnetically attracted to each other.
The second magnetic member 130 is also a magnetic component, and 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 higher 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 contact with the magnetic attraction member 120 in an attraction manner.
When the temperature of the first magnetic member 110 is lower than the first preset temperature, the first magnetic member 110 and the magnetic attraction member 120 are in an attraction contact, 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, and the controlled device entering the second state may refer to the controlled device being turned on, or may refer to the controlled device being in a working state with higher energy consumption, such as high-speed operation.
The working process of the temperature control module 100 disclosed by the embodiment of the invention is as follows:
in a specific working process, as the working is performed, the controlled device generates heat and further causes a temperature rise of the controlled device, because the first magnetic member 110 is in heat conduction connection with the controlled device, the temperature of the first magnetic member 110 also rises along with the temperature rise of the controlled device, when the temperature of the first magnetic member 110 is higher than a first preset temperature, the magnetism of the first magnetic member 110 is weakened or even disappears, in this case, because the magnetism of the magnetic attraction member 120 and the magnetism of the second magnetic member 130 attract each other, so as to contact with the second magnetic member 130, and simultaneously separate from the first magnetic member 110, in this case, the device control module 160 can control the controlled device to enter a first state.
When the temperature of the controlled device is lower, the temperature of the first magnetic member 110 is lower, and when the temperature of the first magnetic member 110 is lower than the first preset temperature, the magnetic attraction of the magnetic attraction member 120 is higher due to the stronger magnetic property of the first magnetic member 110, so that the magnetic attraction member 120 is separated from the second magnetic member 130, and meanwhile, the magnetic attraction member 120 contacts with the first magnetic member 110, and under such a condition, the device control module 160 controls the controlled device to enter the second state.
As can be seen from the above working process, the temperature control module 100 disclosed in the embodiment of the present invention can control the controlled device to switch between the first state and the second state according to the temperature of the controlled device in the terminal device, so as to prevent the temperature of the controlled device from continuously increasing.
In the embodiment of the present invention, the magnetic element 120 is a moving member of the temperature control module 100, so as to facilitate the magnetic element 120 to move to a position where the magnetic element is in contact with the first magnetic element 110 or the second magnetic element 130, in a preferable embodiment, the temperature control module 100 disclosed in the embodiment of the present invention may further include a fixing element 140, and the magnetic element 120 may be connected to the fixing element 140 through an elastic element 150. The elastic member 150 can play a role of auxiliary driving by its own elasticity.
There are various positions for the fixing element 140, and referring to fig. 2 again, in an embodiment, the magnetic element 120 may be located between the fixing element 140 and the first magnetic element 110. The second magnetic member 130 is disposed between the fixing member 140 and the magnetic member 120. Of course, the embodiment of the present invention does not limit the specific position of the fixing member 140 as long as the installation position can provide the installation base for the elastic member 150 to perform the corresponding function.
Specifically, as shown in fig. 2, the elastic member 150 can apply an elastic force to the magnetic attraction member 120 to approach the first magnetic member 110, and the elastic force applied by the elastic member 150 is in the same direction as the magnetic force applied by the first magnetic member 110. The first predetermined temperature may be the curie temperature of the first magnetic member 110, and when the temperature of the first magnetic member 110 is higher than the curie temperature of the first magnetic member 110, the magnetism of the first magnetic member 110 disappears, so that the magnetic force exerted by the second magnetic member 130 overcomes the elastic force of the elastic member 150, and the magnetic member 120 is separated from the first magnetic member 110. When the temperature of the first magnetic member 110 is lower than the curie temperature thereof, the magnetism of the first magnetic member 110 is recovered, and the magnetic attraction member 120 can be in attraction contact with the first magnetic member 110 under the action of the magnetic attraction force of the first magnetic member 110 and the elastic force of the elastic member 150.
In a more preferable aspect, the second magnetic member 130 may be located at one side of the elastic member 150. This arrangement makes the arrangement of the temperature control module 100 more compact, which is further advantageous to reduce the occupied space of the temperature control module 100.
The elastic member 150 may have various structures, specifically, the elastic member 150 may be a telescopic spring, an elastic rubber block, a metal bent elastic sheet, and the like, and the embodiment of the present invention does not limit the specific kind of the elastic member 150.
