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. 1-2, an embodiment of the present invention discloses an electronic device, which may specifically include a housing 100, a driving mechanism 200, and a heat dissipation device 300.

The case 100 has an inner cavity to provide a mounting space for constituent members of the electronic apparatus.

The housing 100 of different configurations differs in the components forming the frame. For example, the case 100 may include a front case, a rear cover, and a middle frame disposed therebetween. The rim may be formed on the middle frame. In this case, the frame serves as a part of the middle frame. For another example, the housing 100 includes a front cover and a rear cover, and the bezel may be molded on the rear cover. The first opening 110 may also be a card pin hole, a sub microphone hole, or an earphone hole of the electronic device, and one or more first openings 110 may be provided, which is not limited herein.

The driving mechanism 200 is disposed in the housing 100, and in a specific embodiment, the driving mechanism 200 may include a driving motor 220, a lead screw 230 connected to the driving motor 220, and a driving block threadedly engaged with the lead screw 230. The movable portion 320 is connected with the driving mechanism 200, and specifically, the movable portion 320 is connected with the driving block. The driving motor 220 may apply a force to the driving block through the lead screw 230, so that the driving block moves the movable portion 320. Specifically, the driving motor 220 drives the lead screw 230 to rotate, and the lead screw 230 applies a force to the driving block to drive the driving block to move. The gas exchange chamber 330 compresses or expands by moving the movable portion 320 connected thereto by the driving block, so that air enters or exits the housing 100 through the first opening 110. Of course, the driving mechanism 200 may also be other structures capable of outputting power, and the disclosure is not limited thereto.

In the embodiment of the present invention, the inner cavity of the casing 100, the external environment of the casing 100 and the gas exchange cavity 330 of the heat dissipation device 300 are connected. The gas exchange cavity 330 drives the movable portion 320 to move through the driving mechanism 200 to compress or expand, so that convection between hot air in the inner cavity of the casing 100 and cold air in the external environment of the casing 100 is realized, the purpose of heat dissipation of the electronic device is achieved, and the safety and reliability of the electronic device are improved.

In a preferred embodiment, the housing 100 further has a second opening 120, and the electronic device further includes a lifting module 400, and specifically, the lifting module 400 includes at least one of a camera module, a sensor, a fingerprint identification module, a receiver, and a light supplement lamp. The lifting module 400 is connected to the driving mechanism 200, and the driving mechanism 200 drives the lifting module 400 to extend out of the housing 100 or retract into the housing 100 through the second opening 120. When the lifting module 400 needs to be switched to the working state, it can extend out of the housing 100 through the second opening 120 on the housing 100; when the operation of the lifting module 400 is completed, it can be retracted into the housing 100 through the second opening 120 of the housing 100. In this scheme, the lifting module 400 does not occupy the display area of the electronic device, so the screen ratio of the electronic device is large. In addition, the embodiment enables the lifting module 400 and the movable part 320 to share one driving mechanism 200, thereby saving the space for installing the driving device for the lifting module 400 and improving the space utilization rate of the inner cavity of the housing 100. Meanwhile, the manufacturing cost of the electronic equipment is reduced. In addition, air can also enter and exit the housing 100 through the second opening 120, so the heat sink 300 can also dissipate heat of the lifting module 400.

The lifting module 400 and the movable portion 320 may be connected to the driving mechanism 200 at the same time, and the driving mechanism 200 drives the lifting module 400 and the movable portion 320 to move at the same time, but this structure requires the lifting module 400 and the movable portion 320 to move together, so that the operability of the electronic device is poor and the user experience is poor. In order to solve the above problem, in an alternative embodiment, the driving mechanism 200 further includes a moving rod 210, the moving rod 210 is located between the movable portion 320 and the lifting module 400, the moving rod 210 moves along its extending direction between a first position and a second position, in the first position, the moving rod 210 is connected to the lifting module 400, and the driving mechanism 200 only drives the lifting module 400; in the second position, the movable rod 210 is connected to the movable portion 320, and the driving mechanism 200 drives only the movable portion 320 to move. Specifically, a driving mechanism may be further provided to drive the moving rod 210, and the driving mechanism may be a telescopic cylinder, and the telescopic cylinder drives the moving rod 210 to move between the first position and the second position. By the structure, the lifting module 400 and the heat dissipation device 300 move independently, operability of the electronic equipment is improved, and user experience of the electronic equipment is improved. Moreover, since the frequency of the heat dissipation function is different from that of the lifting module 400, the frequency of the heat dissipation function is usually higher, so that the function of the electronic device can be optimized by the embodiment. Specifically, when the control system of the electronic device detects that the temperature of the internal component exceeds the set threshold, the control system of the electronic device sends an instruction to push the moving rod 210 to the second position, so as to start the heat dissipation function; when the lifting module 400 needs to be operated, the control system of the electronic device sends an instruction to push the moving rod 210 back to the first position, so that the lifting module 400 works normally.

In an alternative embodiment, at least one of the lifting module 400 and the movable portion 320 is provided with a first magnetic attraction portion 500. The movable rod 210 is provided with a second magnetic attraction part 600, and the movable rod 210 moves between a first position and a second position under the action of the first magnetic attraction part 500 and the second magnetic attraction part 600. In this scheme, the position of the moving rod 210 can be changed by changing the magnetic field directions of the first magnetic part 500 and the second magnetic part 600, so that the control method is simple and reliable, the reversing speed is high, and the structure is compact. Specifically, the first magnetic attraction part 500 may employ an electromagnet, and the second magnetic attraction part 600 may employ a permanent magnet. The direction of the magnetic field of the first magnetic attraction part 500 changes, so that the direction of the acting force of the second magnetic attraction part 600 changes, and the moving rod is pushed to move between the first position and the second position.

The heat sink 300 of the above embodiment may adopt a pump structure, and the pump structure mainly includes a cylinder body and a push rod, the cylinder body is fixed to the housing 100 as a fixed portion 310, and the push rod is movable relative to the cylinder body as a movable portion 320. However, in this structure, the housing 100 has enough space for the push rod to move, and therefore, the space inside the housing 100 is occupied, and for this reason, the heat sink 300 may be a compression airbag. The compression balloon is constructed in a small size and has a short movable partial stroke, so that it occupies a small inner space of the housing 100.

The shielding cover is arranged in the electronic equipment to shield the interference of external electromagnetic waves to the internal components of the electronic equipment, and simultaneously, the interference of the electromagnetic waves among the internal components of the electronic equipment is reduced. The heat generated by the components causes the hot air in the inner cavity of the shielding cover to gather, and the inner cavity of the shielding cover is not communicated with the inner cavity of the shell 100, so that the hot air in the inner cavity of the shielding cover cannot be discharged, and the heat dissipation performance of the electronic equipment is low. In a preferred embodiment, the heat dissipation device 300 further includes an air duct 340, and the electronic device further includes a first shielding cover 700, and components mounted inside the first shielding cover 700 generate heat more severely, so that heat is intensively dissipated. For example, components such as a cpu are mounted inside the first shield cover 700. The first shielding cover 700 is provided with a first air hole 710 and a second air hole 720, the first air hole 710 is communicated with the inner cavity of the first shielding cover 700, the inner cavity of the first shielding cover 700 is communicated with the inner cavity of the housing 100 through the second air hole 720, one end of the air duct 340 is communicated with the gas exchange cavity 330, and the other end is communicated with the first air hole 710. When the gas exchange cavity 330 is compressed, the hot air in the inner cavity of the first shielding cover 700 is blown out through the air duct 340 connected with the gas exchange cavity, so as to reduce the temperature inside the first shielding cover 700; when the gas exchange chamber 330 is expanded, cool air outside the housing 100 may be introduced into the inner cavity of the first shield cover 700, further reducing the temperature inside the first shield cover 700. The embodiment enables the heat dissipation effect of the electronic equipment to be better.

In order to improve the efficiency of the air discharge and entrance into the first shield cover 700, in an alternative embodiment, the axis of the first air hole 710 coincides with the axis of the second air hole 720. In other words, the first air holes 710 and the second air holes 720 are oppositely arranged, so that the speed of air entering and exiting the first air holes 710 or the second air holes 720 is increased, the air inlet and exhaust speed inside the first shielding cover 700 is increased, and the heat dissipation efficiency of the electronic device is improved.

The electronic device further includes a second shielding cover 800, the second shielding cover 800 is a shielding cover that is not connected to the air duct 340, and the second shielding cover 800 has a lower internal temperature than the first shielding cover 700. The second shield cover 800 is spaced apart from the first shield cover 700 to form the ventilation channel 350 therebetween, and the second air holes 720 and the first opening 110 face the ventilation channel 350. The hot air inside the first shield cover 700 can be more rapidly discharged out of the housing 100 along the ventilation channel 350 so that it does not collect inside the housing 100, and the cold air entering the housing 100 can also be more rapidly entered into the first shield cover 700 along the ventilation channel 350, further improving the heat dissipation efficiency of the first shield cover 700, thereby further enhancing the heat dissipation performance of the electronic device.

In the above embodiments, optionally, the electronic device further includes a heat conducting device 900, and the components in the housing 100 are in contact with the heat conducting device 900. The structure enables heat generated by the components to be transferred to the heat conducting device 900, and the heat is radiated or transferred to the appearance part of the electronic equipment through the heat conducting device 900, so that heat dissipation is achieved, and the heat dissipation performance of the electronic equipment is better. The appearance component may be a housing 100 or a display screen of the electronic device. Specifically, the heat conduction device 900 may be a heat conduction pipe or a heat dissipation film, and the specific structure of the heat conduction device 900 is not limited herein.
