Abstract
Description
Technical Field
[0001] This application belongs to the technical field of communication devices, and particularly relates to an electronic device. Background Art
[0002] In the related art, the heat dissipation solution for a rollable screen mobile phone is the same as that of a conventional mobile phone, which adopts passive heat dissipation. That is, materials such as vapor chambers, heat pipes, thermal grease, thermal gel, graphite thermal pads, copper foils, magnesium alloys, or aluminum alloys are used to evenly distribute the heat of mobile phone chips, cameras, batteries, etc. throughout the mobile phone, and then the mobile phone transfers the heat to the external environment through heat radiation.
[0003] However, since a rollable screen mobile phone has more internal components, its heat generation is much greater than that of an ordinary mobile phone. Therefore, the conventional heat dissipation method cannot meet the heat dissipation requirements of the rollable screen mobile phone. Summary of the Invention
[0004] This application aims to provide an electronic device to solve or improve one of the technical problems that the heat dissipation effect of the electronic device cannot meet the requirements.
[0005] To solve the above technical problems, this application is implemented as follows:
[0006] In a first aspect, this application provides an electronic device, including:
[0007] A first housing having at least one speaker hole;
[0008] A second housing, with a first through hole and a second through hole respectively provided on different side walls of the second housing. The second housing is movable relative to the first housing to enable the electronic device to switch between an unfolded state and a folded state. When the electronic device is in the unfolded state, a cavity is formed in the second housing, and both the first through hole and the second through hole are connected to the cavity. When the electronic device is in the folded state, at least one of the first through hole and the second through hole corresponds to the speaker hole.
[0009] In an embodiment of this application, the electronic device includes a first housing and a second housing. The first housing and the second housing can perform a relative translational movement. The second housing can move towards the first housing and also move away from the first housing. Furthermore, when the second housing moves away from the first housing, it can move to the unfolded state, and when the second housing moves towards the first housing, it can move to the folded state. Then, a flexible screen assembly can be provided on the first housing and the second housing. As the second housing moves, the flexible screen assembly can switch between an extended state and a wound state, thereby increasing the display area of the electronic device and reducing the space occupied when the electronic device is stored.
[0010] Among them, a first through hole and a second through hole are respectively provided on different side walls of the second housing. When the first housing and the second housing are in the unfolded state, a cavity is formed in the second housing, and both the first through hole and the second through hole communicate with the cavity. Thus, the heat accumulated in the cavity can be discharged through the first through hole and the second through hole. Moreover, a speaker hole is provided on the first housing. When the electronic device is in the folded state, at least one of the first through hole and the second through hole corresponds to the speaker hole. Thus, the electronic device can emit sound in the folded state, and can also release heat outward, and at the same time, the first through hole and the second through hole can be hidden, thereby improving the heat dissipation effect of the electronic device.

[0035] The following will describe the electronic device 100 according to an embodiment of the present application in conjunction with Figures 1 to 16 Figure [not provided in the original, should be added here].
[0036] As Figures 1 to 8 shown, the present application provides an electronic device 100, including: a first housing 110 having at least one speaker hole 118; a second housing 120, with a first through hole 124 and a second through hole 126 respectively provided on different side walls 134 of the second housing 120. The second housing 120 is movable relative to the first housing 110 to enable the electronic device 100 to switch between an unfolded state and a folded state. When the electronic device 100 is in the unfolded state, a cavity 122 is formed in the second housing 120, and both the first through hole 124 and the second through hole 126 are in communication with the cavity 122. When the electronic device 100 is in the folded state, at least one of the first through hole 124 and the second through hole 126 corresponds to the speaker hole 118.
[0037] In an embodiment of the present application, the electronic device 100 includes a first housing 110 and a second housing 120. The first housing 110 and the second housing 120 can perform a relative translational movement. The second housing 120 can move towards the first housing 110 and can also move away from the first housing 110. As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, when the second housing 120 moves away from the first housing 110, it can move to the unfolded state. As Figure 6 , Figure 7 and Figure 8 shown, when the second housing 120 moves towards the first housing 110, it can move to the folded state. Furthermore, a flexible screen assembly 140 can be provided on the first housing 110 and the second housing 120. As the second housing 120 moves, the flexible screen assembly 140 can switch between an extended state and a wound state, thereby realizing an increase in the display area of the electronic device 100 and a reduction in the space occupied when the electronic device 100 is stored.
[0038] Note: In the translation of , since the figure number is not provided in the original text, it is marked as [not provided in the original, should be added here] for the need of a complete description. In actual translation, the correct figure number should be filled in according to the original patent content.Among them, a first through hole 124 and a second through hole 126 are respectively provided on different side walls 134 of the second housing 120. When the first housing 110 and the second housing 120 are in the unfolded state, a cavity 122 is formed in the second housing 120. Both the first through hole 124 and the second through hole 126 are connected to the cavity 122. Thus, the heat accumulated in the cavity 122 can be discharged through the first through hole 124 and the second through hole 126. Moreover, a speaker hole 118 is provided on the first housing 110. When the electronic device 100 is in the folded state, at least one of the first through hole 124 and the second through hole 126 corresponds to the speaker hole 118. Thus, the electronic device 100 can emit sound in the folded state, and can also release heat outward, and at the same time can hide the first through hole 124 and the second through hole 126, thereby improving the heat dissipation effect of the electronic device 100.
[0039] The speaker hole 118 has one or more.
[0040] Such as Figure 10 、 Figure 11 、 Figure 13 And Figure 14 As shown, as a possible implementation manner, the second housing 120 includes a bottom wall 136, and the distance between the first through hole 124 and the bottom wall 136 is different from the distance between the second through hole 126 and the bottom wall 136.
[0041] Specifically, the distance between the first through hole 124 and the bottom wall 136 is different from the distance between the second through hole 126 and the bottom wall 136. That is, when the bottom wall 136 of the first housing 110 of the electronic device 100 is placed flat downward, and when the electronic device 100 is in the unfolded state, the heights of the first through hole 124 and the second through hole 126 are different. Thus, the heat of the electronic device 100 will be transferred to the cavity 122. Then, the temperature of the air in the cavity 122 will rise, and the density of hot air is low while the density of cold air is high. Therefore, the hot air in the cavity 122 will be discharged from the one with a higher position among the first through hole 124 and the second through hole 126, and fresh air from the outside will be inhaled through the one with a lower position among the first through hole 124 and the second through hole 126, thereby realizing the circulation of gas and improving the heat dissipation effect of the electronic device 100.
[0042] Such as Figure 13 Shown, the distance between the first through hole 124 and the bottom wall 136 is L1. As Figure 14 Shown, the distance between the second through hole 126 and the bottom wall 136 is L2, and L1 and L2 are not equal. That is, as Figure 11 Shown, the first through hole 124 and the second through hole 126 are not at the same height in the thickness AB direction of the second housing 120.
[0043] Furthermore, as Figure 10As shown, the first through hole 124 and the second through hole 126 are respectively disposed on two opposite side walls 134 of the second housing 120.
[0044] Specifically, in a state where the electronic device 100 is placed flat, it may be that the bottom wall 136 of the first housing 110 faces downward or the display part of the flexible screen assembly 140 faces downward. There is a natural height difference between the first through hole 124 and the second through hole 126. At this time, the circulation of air flow can be realized. When the electronic device 100 is in an upright state, there is also a height difference between the first through hole 124 and the second through hole 126, and the circulation of air flow can be realized. Since there is a height difference between the first through hole 124 and the second through hole 126 in the thickness AB direction of the second housing 120, in most cases, there is a height difference between the first through hole 124 and the second through hole 126 when the electronic device 100 is placed somewhere or the user carries the electronic device 100. Therefore, the heat dissipation effect of the electronic device 100 can be ensured.
[0045] During the use of the electronic device 100, the battery, the processor 210 or the camera assembly generates heat, and the heat is transferred to the cavity 122 formed by the first housing 110 and the second housing 120. As Figure 3 shown, wherein the arrow indicates the sense of air flow direction. When the bottom wall 136 of the first housing 110 of the electronic device 100 faces downward and the first through hole 124 is higher than the second through hole 126, the hot air in the cavity 122 flows out from the first through hole 124, and the cold air from the outside enters the cavity 122 through the second through hole 126, thereby realizing the convection cycle of air and improving the heat dissipation effect. Of course, the above is only an embodiment of the present application. When the display part of the flexible screen assembly 140 of the electronic device 100 faces downward, the hot air in the cavity 122 flows out from the second through hole 126, and the cold air from the outside enters the cavity 122 through the first through hole 124.
[0046] As Figure 9 shown, as a possible implementation manner, the first housing 110 includes an air flow channel. When the electronic device 100 is in an unfolded state, the air flow channel communicates the cavity 122 and the inside of the first housing 110. The electronic device 100 further includes: a fan assembly 180, and the fan assembly 180 includes a fan 182, and the fan 182 is disposed at the air flow channel.
[0047] Specifically, the electronic device 100 further includes a fan assembly 180. An air flow channel is provided on the first housing 110. When the electronic device 100 is in the unfolded state, the air flow channel communicates the cavity 122 and the interior of the first housing 110. The fan assembly 180 includes a fan 182, and the fan 182 is disposed at the air flow channel. Thus, when the first housing 110 and the second housing 120 are in the unfolded state and the fan assembly 180 is operating, the fan assembly 180 can promote the air flow between the cavity 122 and the interior of the first housing 110, thereby enhancing the heat dissipation effect of the electrical components in the first housing 110.
[0048] Among them, the air flow channel is provided on the side of the first housing 110 facing the cavity 122. The fan 182 can be a silent fan 182.
[0049] Such as Figure 2 、 Figure 4 、 Figure 5 and Figure 7 As shown, as a possible implementation, the electronic device 100 further includes: a drive assembly 150 disposed on the first housing 110; a transmission assembly 170 disposed on the first housing 110 and connected to the second housing 120; wherein, the drive assembly 150 has a first state and a second state. When the drive assembly 150 is in the first state, the drive assembly 150 cooperates with the transmission assembly 170. When the drive assembly 150 is in the second state, the drive assembly 150 cooperates with the fan assembly 180.
[0050] Specifically, the electronic device 100 further includes a drive assembly 150 and a transmission assembly 170. The drive assembly 150 is disposed on the first housing 110. The transmission assembly 170 is connected to the drive assembly 150 and is also connected to the second housing 120. The drive assembly 150 can drive the second housing 120 through the transmission assembly 170, thereby realizing the automatic unfolding of the first housing 110 and the second housing 120.
[0051] And the drive assembly 150 has a first state and a second state. When the drive assembly 150 is in the first state, it cooperates with the transmission assembly 170 and does not cooperate with the fan assembly 180. The drive assembly 150 can drive the second housing 120 to move. When the drive assembly 150 is in the second state, it cooperates with the fan assembly 180 and does not cooperate with the transmission assembly 170. The drive assembly 150 can drive the fan assembly 180 to operate. Thus, by using one drive assembly 150, it can simultaneously realize the driving of the states of the first housing 110 and the second housing 120, and also realize the driving of the fan assembly 180, thereby saving costs and reducing the weight of the electronic device 100.
[0052] When the temperature of the electronic device 100 is not lower than the temperature threshold, a prompt is issued to ask the user whether to unfold the electronic device 100 to improve the heat dissipation effect, and then in response to the input of the user's expectation to unfold the electronic device 100, the driving component 150 is driven to operate, so that the first housing 110 and the second housing 120 are in the unfolded state, improving the heat dissipation effect of the electronic device 100.
[0053] Furthermore, as Figure 2 and Figure 7 shown, a bearing 130 and a support member 132 are provided on the second housing 120. The flexible screen assembly 140 is wound around the bearing 130. The support member 132 is connected to the transmission component 170. Then the transmission component 170 can drive the support member 132 to move, the support member 132 drives the second housing 120 to move, and the flexible screen assembly 140 moves around the bearing 130, thereby realizing the unfolding and folding of the first housing 110 and the second housing 120.
[0054] Moreover, the support member 132 is a comb-shaped support. One end of the support member 132 is connected to the transmission component 170, and the other end is connected to the bearing 130. Then when the driving component 150 drives the transmission component 170 to operate, the support member 132 moves, driving the bearing 130 to move, and then driving the second housing 120 to move, realizing the stretching and folding of the first housing 110 and the second housing 120.
[0055] When the second housing 120 gradually moves away from the first housing 110, the volume of the cavity 122 gradually increases. When the second housing 120 gradually moves closer to the first housing 110, the volume of the cavity 122 gradually decreases.
[0056] In addition, multiple groups of the driving component 150, the fan component 180, and the transmission component 170 can be provided, for example: two groups, three groups, or four groups, etc., so as to improve the smoothness of the movement of the first housing 110 and the second housing 120 and improve the air supply effect of the fan component 180.
[0057] As Figure 9 shown, as a possible implementation manner, the driving component 150 includes: a motor 152 movably provided on the first housing 110; a telescopic member 154 provided on the first housing 110 and connected to the motor 152. The telescopic member 154 has an extended state and a contracted state. When the telescopic member 154 is in the extended state, the driving component 150 is in one of the first state and the second state. When the telescopic member 154 is in the contracted state, the driving component 150 is in the other of the first state and the second state.
[0058] Specifically, the driving component 150 includes a motor 152 and a telescopic member 154 disposed in the first housing 110. The telescopic member 154 is capable of driving the motor 152 to move. The motor 152 can drive the fan assembly 180 and the transmission assembly 170. The telescopic member 154 has an extended state and a contracted state. When the telescopic member 154 is in the extended state, one of the motor 152 and the transmission assembly 170 cooperates with the fan assembly 180, and the other of the motor 152 and the transmission assembly 170 does not cooperate. The motor 152 can drive the second housing 120 to move alone, or drive the fan assembly 180 to operate alone.
[0059] For example, when the telescopic member 154 is in the extended state, the motor 152 cooperates with the fan assembly 180, and the motor 152 and the transmission assembly 170 do not cooperate. The motor 152 can drive the fan assembly 180 to operate. When the telescopic member 154 is in the contracted state, the motor 152 cooperates with the transmission assembly 170, and the motor 152 and the fan assembly 180 do not cooperate. The motor 152 can drive the first housing 110 and the second housing 120 to move.
[0060] Furthermore, by using one motor 152, the driving of the states of the first housing 110 and the second housing 120 is achieved simultaneously, and the driving of the fan assembly 180 is also realized, thereby saving costs and reducing the weight of the electronic device 100.
[0061] Further, the telescopic member 154 can drive the motor 152 by extending and contracting. The driving component 150 further includes a second spring 162. The second spring 162 and the telescopic member 154 are respectively disposed on both sides of the motor 152. Thus, the second spring 162 can drive the motor 152 to reset.
[0062] Thus, when the telescopic member 154 contracts, the second spring 162 extends, and when the telescopic member 154 extends, the second spring 162 contracts.
[0063] Further, the electronic device 100 further includes a position detection component 220 disposed in the first housing 110 for detecting the position of the motor 152 to determine whether the motor 152 moves to a specific position, improving the cooperation accuracy between the motor 152 and the transmission assembly 170, and between the motor 152 and the fan assembly 180, and achieving closed-loop control of the telescopic member 154.
[0064] Moreover, when the temperature of the electronic device 100 is lower than the temperature threshold, the telescopic member 154 makes the motor 152 and the transmission assembly 170 cooperate. At this time, the telescopic member 154 can be in a power-off state. When the temperature of the electronic device 100 is not lower than the temperature threshold, the telescopic member 154 works to drive the motor 152 to move, so that the motor 152 and the fan assembly 180 cooperate.
[0065] The movable direction of the motor 152 and the movable direction of the second housing 120 may be the same or different. For example: The movable direction of the motor 152 and the movable direction of the second housing 120 may be perpendicular to each other or at an angle.
[0066] Such as Figure 4 , Figure 5 and Figure 9 As shown, as a possible implementation, one end of the telescopic member 154 is connected to the first housing 110, and the other end is connected to the motor 152. When the telescopic member 154 switches between the extended state and the contracted state, it drives the motor 152 to move along a direction perpendicular to the output shaft of the motor 152.
[0067] Specifically, one end of the telescopic member 154 is connected to the first housing 110, and the other end is connected to the motor 152. It can be connected to the peripheral side of the motor 152. And when the telescopic member 154 switches between the extended state and the contracted state, the motor 152 moves along a direction perpendicular to the output shaft of the motor 152, thereby changing the position of the output shaft of the motor 152, and thus realizing the adjustment of the object driven by the motor 152. That is, during the process of the telescopic member 154 switching between the extended state and the contracted state, it will pull or push the motor 152 to move.
[0068] Among them, the first housing 110 includes an installation part 112. The installation part 112 encloses an installation cavity in the first housing 110. The motor 152 is arranged in the installation cavity. The telescopic member 154 connects the motor 152 and the first housing 110. For example, the telescopic member 154 is connected to the installation part 112, or the telescopic member 154 is connected to a part of the first housing 110 other than the installation part 112, so that the operation of the telescopic member 154 can drive the motor 152 to move.
[0069] The telescopic member 154 includes: a shape memory alloy, an electric telescopic rod, a pneumatic cylinder, a hydraulic cylinder or an electromagnetic telescopic member.
[0070] Specifically, the telescopic member 154 can adopt a shape memory alloy, an electric telescopic rod, a pneumatic cylinder, a hydraulic cylinder or an electromagnetic telescopic member.
[0071] Taking the shape memory alloy as an example, the displacement S of heat shrinkage = L×n, where L is the active wire length of the shape memory alloy, and n is the shrinkage rate of the shape memory alloy at a specific temperature. Therefore, the shape memory alloy can elongate when electrified and heated. Furthermore, through the detection of the position detection component 220, it is judged whether the motor 152 moves in place, so that parameters such as the energizing current and voltage of the shape memory alloy can be controlled to form a control loop.
[0072] Such as Figure 9As shown, as a possible implementation, the transmission assembly 170 includes: a lead screw 172, which is drivingly connected to the driving assembly 150, and when the driving assembly 150 is in the first state, the driving assembly 150 cooperates with the lead screw 172; a slider 174, which is arranged on the lead screw 172, and the slider 174 is connected to the second housing 120.
[0073] Specifically, the transmission assembly 170 includes a lead screw 172 and a slider 174. The lead screw 172 is connected to the driving assembly 150, and the slider 174 is arranged on the lead screw 172. Then, the driving assembly 150 drives the lead screw 172 to rotate, so that the lead screw 172 drives the slider 174 to move, realizing the driving of the second housing 120.
[0074] Further, one end of the lead screw 172 is connected to the driving assembly 150, and the other end is rotatably connected to the first housing 110 to support the lead screw 172.
[0075] One end of the support member 132 is connected to the slider 174, and the other end is connected to the bearing 130.
[0076] As Figure 9 and Figure 12 As shown, as a possible implementation, the driving assembly 150 further includes: a first gear 156, which is arranged on the motor 152; a second gear 158, which is arranged on the transmission assembly 170; a third gear 160, which is arranged on the fan assembly 180; wherein, when the driving assembly 150 is in the first state, the first gear 156 meshes with the second gear 158, and when the driving assembly 150 is in the second state, the first gear 156 meshes with the third gear 160.
[0077] Specifically, the driving assembly 150 further includes a first gear 156, a second gear 158 and a third gear 160. The first gear 156 is arranged on the motor 152, and the motor 152 drives the first gear 156 to rotate. The second gear 158 is arranged on the transmission assembly 170, and the third gear 160 is arranged on the fan assembly 180. The first gear 156 and the second gear 158 are adapted to each other, and the first gear 156 and the third gear 160 are adapted to each other. Then, when the telescopic member 154 is in the first state, the first gear 156 meshes with the second gear 158. Thus, when the motor 152 operates, the first gear 156 drives the second gear 158 to rotate, and the second gear 158 drives the transmission assembly 170 to move, realizing the movement of the second housing 120. When the telescopic member 154 is in the second state, the first gear 156 meshes with the third gear 160. Thus, when the motor 152 operates, the first gear 156 drives the third gear 160 to rotate, and the third gear 160 drives the fan assembly 180 to operate, realizing the air supply of the fan assembly 180 to the cavity 122 or the air suction from the cavity 122.
[0078] Among them, the transmission direction from the first gear 156 to the second gear 158 is a speed reduction transmission, and the transmission direction from the first gear 156 to the third gear 160 is also a speed reduction transmission. The first gear 156 is arranged on the output shaft of the motor 152. The second gear 158 is arranged on the lead screw 172. The fan assembly 180 includes a fan 182 and a connecting rod 184. The third gear 160 is arranged on the connecting rod 184, and the fan 182 is arranged on the connecting rod 184.
[0079] Moreover, the lead screw 172 and the connecting rod 184 are rotatably passed through the mounting portion 112.
[0080] When the temperature of the electronic device 100 is lower than the temperature threshold, the telescopic member 154 causes the motor 152 and the transmission assembly 170 to cooperate, that is, the first gear 156 and the second gear 158 are engaged, and the first gear 156 and the third gear 160 are spaced apart. At this time, the telescopic member 154 can be in a power-off state. When the temperature of the electronic device 100 is not lower than the temperature threshold, the telescopic member 154 operates to drive the motor 152 to move, so that the motor 152 and the fan assembly 180 cooperate, that is, the first gear 156 and the third gear 160 are engaged, and the first gear 156 and the second gear 158 are spaced apart.
[0081] As Figure 4 and Figure 5 shown, as a possible implementation manner, the speaker holes 118 include a first speaker hole 114 and a second speaker hole 116. When the electronic device 100 is in the folded state, the first speaker hole 114 corresponds to the first through hole 124, and the second speaker hole 116 corresponds to the second through hole 126.
[0082] Specifically, the speaker holes include a first speaker hole 114 and a second speaker hole 116. The first speaker hole 114 and the second speaker hole 116 are arranged on the first housing 110. When the first housing 110 and the second housing 120 are in the folded state, the first speaker hole 114 corresponds to the first through hole 124, and the second speaker hole 116 corresponds to the second through hole 126, thereby achieving the effect of dual speakers.
[0083] The electronic device 100 further includes: a first speaker 192 and a second speaker 194. The first speaker 192 is arranged on the first housing 110 and is arranged corresponding to the first speaker hole 114. The second speaker 194 is arranged on the first housing 110 and is arranged corresponding to the second speaker hole 116. The first speaker hole 114 and the second speaker hole 116 are respectively arranged on two opposite sides of the first housing 110.
[0084] As Figure 15As shown, as a possible implementation, it further includes: a temperature detection component 200 disposed on the first housing 110 or the second housing 120; a processor 210 disposed on the first housing 110 or the second housing 120 and electrically connected to the temperature detection component 200 and the driving component 150, and the processor 210 controls the driving component 150 based on the detection result of the temperature detection component 200.
[0085] Specifically, the electronic device 100 further includes a temperature detection component 200 and a processor 210. The temperature detection component 200 is disposed on the first housing 110 or the second housing 120. The temperature detection component 200 can detect the temperature of the electronic device 100. The processor 210 is electrically connected to the temperature detection component 200 and the driving component 150, and the processor 210 controls the driving component 150 according to the detection result of the temperature detection component 200.
[0086] For example: The processor 210 obtains the temperature detected by the temperature detection component 200. When the temperature of the electronic device 100 is not lower than the temperature threshold, the processor 210 issues a prompt instruction. When the user selects to expand the electronic device 100, the processor 210 controls the driving component 150 to operate, so that the electronic device 100 expands.
[0087] Or, the processor 210 obtains the temperature detected by the temperature detection component 200. When the temperature of the electronic device 100 is not lower than the temperature threshold, the processor 210 issues a prompt instruction. When the user selects to start the fan component 180, the processor 210 controls the driving component 150 to operate, so that the fan component 180 operates.
[0088] Specifically, as Figure 16 shown, the process of the start mode of the fan component 180 in the electronic device 100 is as follows:
[0089] Step 1602: Obtain the temperature of the electronic device;
[0090] Step 1604: Determine whether the temperature of the electronic device is greater than the temperature threshold; if the determination result is yes, execute step 1606, and if the determination result is no, execute step 1608;
[0091] Step 1606: Determine whether an instruction to turn on the fan component is received; if the determination result is yes, execute step 1610, and if the determination result is no, execute step 1608;
[0092] Step 1608: The first gear and the second gear are engaged;
[0093] Step 1610: Determine whether the first housing and the second housing are in an unfolded state; if the determination result is yes, execute step 1616, and if the determination result is no, execute step 1612;
[0094] Step 1612: Control the telescopic member to operate so that the first gear and the second gear mesh with each other;
[0095] Step 1614: Control the motor to operate so that the first housing and the second housing are in the unfolded state;
[0096] Step 1616: Control the telescopic member to operate so that the first gear and the third gear mesh with each other;
[0097] Step 1618: Drive the motor to operate to drive the fan assembly to operate.
[0098] That is, the processor 210 obtains the temperature of the electronic device 100, and determines whether the temperature of the electronic device 100 is greater than the temperature threshold. When the temperature of the electronic device 100 is greater than the temperature threshold, a prompt is issued, for example, a prompt window is discharged through the flexible screen assembly 140, asking whether to turn on the fan assembly 180. After responding to the input of the user to turn on the fan assembly 180, it is determined whether the current first housing 110 and the second housing 120 are in the unfolded state. When the first housing 110 and the second housing 120 are in the unfolded state, control the telescopic member 154 to operate so that the first gear 156 and the third gear 160 mesh with each other. After the position detection component 220 detects that the motor 152 has moved in place, control the motor 152 to operate, thereby controlling the rotation of the fan 182. When the first housing 110 and the second housing 120 are not in the unfolded state, first control the telescopic member 154 to operate so that the first gear 156 and the second gear 158 mesh with each other. After the position detection component 220 detects that the motor 152 has moved in place, control the motor 152 to operate, thereby controlling the movement of the second housing 120 so that the first housing 110 and the second housing 120 are in the unfolded state. After that, control the telescopic member 154 to operate so that the first gear 156 and the third gear 160 mesh with each other. After the position detection component 220 detects that the motor 152 has moved to a specific position, control the motor 152 to operate, thereby controlling the rotation of the fan 182.
[0099] Among them, the processor 210 is electrically connected to the temperature detection component 200, the drive component 150, and the flexible screen component 140.
[0100] Such as Figure 1 、 Figure 2 、 Figure 6 and Figure 7 shown, as a possible implementation manner, it further includes: a flexible screen component 140, which is arranged on the first housing 110 and the second housing 120.
[0101] Specifically, the electronic device 100 further includes a flexible screen assembly 140. The flexible screen assembly 140 is disposed on the first housing 110 and the second housing 120. The flexible screen assembly 140 includes a screen main body 142 and a first spring 144 that are connected to each other. One end of the screen main body 142 is fixedly connected to the first housing 110, and one end of the first spring 144 is fixedly connected to the first housing 110. When the first housing 110 and the second housing 120 are in the extended state, the first spring 144 elongates. When the first housing 110 and the second housing 120 are in the folded state, the first spring 144 shortens.
