Description

Technical Field

[0001] This application relates to the field of electronic product technology, and in particular to a mobile terminal. Background Technology

[0002] With the continuous improvement of the performance of mobile terminals such as smartphones, tablets, and smartwatches, thermal design has become a bottleneck for their performance. Currently, mobile terminals, taking smartphones as an example, often rely on internal heat dissipation through heat pipes, vapor chambers (VCs), graphite sheets, graphene films, and thermal interface materials (TIMs) for natural heat dissipation. However, due to the strict limitations on the size and thickness of mobile terminals, natural heat dissipation is increasingly unable to meet the power consumption requirements of applications such as AI, gaming, video calls, and satellite communications. Active air cooling using fan modules can achieve an equivalent heat transfer coefficient 2 to 10 times that of natural heat dissipation, and can improve heat dissipation capacity by more than 50% compared to natural heat dissipation, making it a crucial way to improve the performance of mobile terminals.

[0003] In related technologies, fan modules are often housed within the casing of mobile terminals. Mobile terminals are prone to drops, compression, or collisions during use and handling. In such situations, fan modules are susceptible to significant localized impact forces, posing a much higher risk than fan modules in stationary applications. This makes them more prone to localized deformation, which can negatively impact performance. Furthermore, over long-term use, dust and fibrous contaminants accumulate on the fan blades and in the air ducts, leading to a continuous decrease in airflow and heat dissipation, as well as noise and other issues. Currently, user maintenance of fan modules is difficult. As a moving component, the reliability of the fan module directly affects the performance of the mobile terminal. Significant deterioration in heat dissipation, noise, or vibration performance necessitates disassembly (e.g., removing the back cover or display screen) for repair. Some mobile terminals have high waterproof and dustproof requirements; disassembly could compromise these seals, potentially rendering the entire terminal unusable. Therefore, disassembly for fan module repair is impractical. In addition, during the disassembly and repair of the fan module, other components or devices such as the housing assembly, side buttons, display screen, and battery may be scratched, which may cause other components or devices to be scrapped.

[0004] Therefore, in mobile terminals using related technologies, it is difficult to perform routine maintenance and repair of the fan module, resulting in low reliability of the fan module and the mobile terminal using the fan module. This hinders its widespread application in the future and restricts the full performance of mobile terminals such as mobile phones. Summary of the Invention

[0005] This application provides a mobile terminal that allows for convenient daily maintenance and repair of its fan module.

[0006] This application provides a mobile terminal, which includes a housing assembly, a fan module, and a first structural member. The first structural member is fixedly disposed on the inner wall of the housing assembly, and the first structural member and the housing assembly enclose a fan mounting cavity. The housing assembly has a fan inlet communicating with the outside of the fan mounting cavity and the outside of the housing assembly, and the fan module is inserted into the fan mounting cavity through the fan inlet. The mobile terminal has a fan locked state and a fan unlocked state. When the mobile terminal is in the fan locked state, the fan module is locked and fixed to the first structural member. When the mobile terminal is in the fan unlocked state, the fan module is released from the first structural member, and the fan module can move between an insertion position and an extension position along a first direction, so that at least a portion of the fan module can extend out to the outside of the housing assembly through the fan inlet, or at least a portion of the fan module can be inserted back into the fan mounting cavity through the fan inlet. The first direction is the insertion and removal direction of the fan module.

[0007] The mobile terminal provided in this application embodiment allows at least a portion of the fan module to extend outside the housing assembly through the fan connector for routine maintenance or repair. This facilitates routine dust removal, cleaning, or replacement of the fan module. After maintenance or repair, the fan module can be reinserted into the fan mounting cavity through the fan connector. Maintenance or repair of the fan module does not require disassembling the display screen, sides, or back cover, and does not damage the seal between the display screen, sides, and back cover. After repair, the display screen, sides, and back cover do not need to be resealed. In summary, the maintenance and repair costs of the fan module are low, the operation is simple, and it is less likely to cause the entire mobile terminal to be scrapped. Furthermore, when repairing the fan module extending outside the housing assembly, the repair tools do not need to be inserted into the housing assembly, minimizing damage to other components or devices of the mobile terminal and reducing the risk of other components or devices being scrapped. The repair cost is low. The mobile terminal provided in this application embodiment offers convenient maintenance and repair of the fan module. Furthermore, by setting the first structural component to form a fan mounting cavity for the insertion of the fan module, it is easy to lock and fix the fan module and the housing assembly and achieve a stable connection. When the mobile terminal is in the fan locked state, the fan module and the housing assembly can be locked and fixed more stably, which is conducive to maintaining the performance of the fan module. When the mobile terminal is in the fan unlocked state, the fan module can move along the first direction, which is easy to operate. The process of extending and inserting the fan module is less likely to cause damage to the whole machine.

[0008] In some possible implementations, the mobile terminal further includes a power supply device and an electrical connection device. The housing assembly also has a device mounting cavity located outside the fan mounting cavity. The power supply device is disposed within the device mounting cavity, and the electrical connection device is partially located within the device mounting cavity and partially within the fan mounting cavity. When the fan module is in the inserted position, the fan module is electrically connected to the power supply device via the electrical connection device. Thus, power can be supplied to the fan module in the inserted position via the power supply device disposed within the device mounting cavity, thereby driving the fan module when it is in the inserted position. When the fan module is in the inserted position, the overall drop resistance of the mobile terminal is good, and the appearance of the mobile terminal remains unchanged.

[0009] In some possible implementations, the mobile terminal further includes a power supply device and an electrical connection device. The housing assembly also has a device mounting cavity located outside the fan mounting cavity. The power supply device is disposed within the device mounting cavity, and the electrical connection device is partially located within the device mounting cavity and partially within the fan mounting cavity. When the fan module is in the extended position, the fan module is electrically connected to the power supply device via the electrical connection device. Thus, power can be supplied to the fan module in the extended position via the power supply device located within the device mounting cavity, thereby driving the fan module when it is in the extended position. When the fan module is in the extended position, it exhibits lower airflow resistance, higher airflow volume, and higher heat dissipation efficiency. Furthermore, when the fan module is in the extended position and operating for heat dissipation, the space within the fan mounting cavity increases, which helps to reduce the flow pressure drop and flow resistance within the fan mounting cavity, thereby increasing the pressure head of the fan module.

[0010] For heavy-load, high-performance applications, the fan module extends out of the housing assembly. When in the extended position, the fan module's air intake, which is located within the fan mounting cavity when in the inserted position, is exposed to the atmosphere. This significantly increases the fan module's air intake area while reducing airflow resistance, resulting in a substantial performance improvement and enabling support for high-load, high-power applications. When the fan module retracts into the inserted position within the housing assembly, the mobile terminal offers improved overall drop resistance.

[0011] In some possible implementations, the fan module is electrically connected to the power supply device via an electrical connector whenever it moves to any position between the insertion and extension positions along the first direction. This allows power to be supplied to the fan module at any position between the insertion and extension positions, enabling it to operate for heat dissipation at any of these positions. Furthermore, it facilitates control of the fan module as it moves between the insertion and extension positions.

[0012] In some possible implementations, the electrical connection device includes an electrical contact terminal fixedly disposed on the first structural member, and the fan module has a first electrical contact portion. The electrical contact terminal includes a second electrical contact portion located within the fan mounting cavity and a connecting portion located within the device mounting cavity, the connecting portion being electrically connected to the power supply device. The first electrical contact portion is used to make electrical contact with the second electrical contact portion, so that the fan module is electrically connected to the power supply device through the electrical contact terminal. This facilitates the electrical connection between the fan module and the power supply device. Furthermore, the electrical connection device has minimal impact on the movement of the fan module.

[0013] In some possible implementations, at least one of the second electrical contact and the first electrical contact is a strip-shaped structure extending along a first direction. When the fan module is in the extended position, a portion of the fan module is located within the fan mounting cavity and a portion extends outward through the fan connector to the outside of the housing assembly, with at least a portion of the first electrical contact located within the fan mounting cavity. As the fan module moves along the first direction to any position between the inserted and extended positions, the first electrical contact makes electrical contact with the second electrical contact. This facilitates electrical connection between the fan module and the power supply device at any position between the inserted and extended positions. Furthermore, the electrical connection device has minimal impact on the movement of the fan module.

[0014] In some possible implementations, the fan module includes a cover and a fan assembly. The cover is fixedly disposed at one end of the fan assembly in a first direction, the fan assembly being inserted into a fan mounting cavity via a fan connector, and the cover being located outside the housing assembly. When the fan module is in the inserted position, the cover covers the outer surface of the housing assembly, and the orthographic projection of the cover onto the outer surface of the housing assembly covers the edge of the housing assembly at the fan connector. As the fan module moves along the first direction between the inserted position and the extended position, at least a portion of the fan assembly extends outward through the fan connector to the outside of the housing assembly, or at least a portion of the fan assembly re-inserts into the fan mounting cavity via the fan connector. Thus, the cover can limit the depth to which the fan module is inserted into the fan mounting cavity.

[0015] In some possible implementations, the mobile terminal further includes a sealing ring disposed between the cover plate and the outer surface of the housing assembly, the sealing ring circumferentially surrounding the fan connector. When the fan module is in the inserted position, the sealing ring is pressed tightly against the outer surface of the cover plate and the housing assembly, sealing the fan module and the housing assembly at the fan connector. Thus, when the fan module is in the inserted position, the sealing performance of the housing assembly is less likely to be compromised by opening the fan connector, resulting in better sealing performance of the mobile terminal and improved overall system reliability.

[0016] In some possible implementations, the fan assembly includes a fan mount and a fan. A cover plate is fixedly disposed at one end of the fan mount in a first direction, and the fan is fixedly disposed on the fan mount, with the fan mounted on one side of the fan mount in a second direction. When the mobile terminal is in the fan-locked state, the fan mount is locked and fixed to the first structural member. When the mobile terminal is in the fan-unlocked state, the fan mount is released from the first structural member, and the fan mount can drive the fan to extend out of the housing assembly through the fan connector, or the fan mount can drive the fan to insert back into the fan mounting cavity through the fan connector. The second direction is perpendicular to the first direction. This facilitates the fan extending completely out of the housing assembly when the fan assembly is partially located within the fan mounting cavity, making fan maintenance or repair easier. Furthermore, it facilitates the installation of heat dissipation structures on the fan assembly, making the fan module structure more flexible.

[0017] In some possible implementations, the fan and fan mount are detachably connected. This allows the fan to be removed from the fan mount for maintenance or repair, making fan maintenance or repair more convenient.

[0018] In some possible implementations, the mobile terminal also includes a heating element disposed within a device mounting cavity of the housing assembly. The fan module has a module air inlet and a module air outlet. When the fan module is in the inserted position, the module air inlet and outlet are located within and communicate with the fan mounting cavity. Thus, the fan module can drive air circulation within the device mounting cavity and the fan mounting cavity, achieving a uniform temperature effect. This eliminates the need for ventilation openings on the outer surface of the mobile terminal and does not affect its appearance.

[0019] In some possible implementations, the mobile terminal further includes a heating element disposed within a device mounting cavity of the housing assembly. The fan mounting cavity is isolated from the device mounting cavity, and the heating element is connected to the first structural member via a thermally conductive component. The fan module has a module air inlet and a module air outlet. Both the module air inlet and the module air outlet communicate with the outside of the housing assembly. This results in good heat dissipation performance for the fan module. Furthermore, when the fan module is in the extended position, it does not compromise the sealing of the device mounting cavity, thus ensuring good sealing performance of the device mounting cavity.

[0020] When the fan mounting cavity and the device mounting cavity are isolated from each other, they are located in two independent sealed waterproof and dustproof systems. The electrical connection parts of the motherboard, battery, chip, and display screen are located in the sealed waterproof and dustproof system of the device mounting cavity, which is physically isolated from the fan mounting cavity. The opening connecting the fan mounting cavity will not affect the dustproof and waterproof properties of the device mounting cavity. The heat generated by the motherboard, battery, chip, display screen and other devices can be transferred to the first structural component through the heat conduction component, and then dissipated to the external environment by the fan module through forced convection, which can give the mobile terminal good heat dissipation performance.

[0021] The fan mounting cavity and the component mounting cavity are located in two independent sealed waterproof and dustproof systems. During routine maintenance and repair of the fan module, or when the waterproofing of the fan mounting cavity fails, the sealed waterproof and dustproof performance of the component mounting cavity, which contains the electrical connections of the motherboard, battery, chip, and display screen, is not affected. The components in the component mounting cavity can work normally and reliably, thus providing strong system fault tolerance design capability and robust system waterproof and dustproof performance for the fan module. This facilitates routine maintenance and non-destructive repair of the fan module.

[0022] In some possible implementations, the waterproof and dustproof rating of the fan mounting cavity is lower than that of the device mounting cavity. This makes the installation and ventilation of the fan module easier.

[0023] In some possible implementations, a heat dissipation structure is fixedly connected to the first structural component, and the heat dissipation structure is located within the fan mounting cavity. This results in high thermal conductivity between the first structural component and the heat dissipation structure, and high efficiency in heat dissipation from the first structural component by the fan module.

[0024] In some possible implementations, the fan assembly of the fan module includes a heat dissipation structure fixedly connected to the fan mount of the fan assembly. The heat dissipation structure exchanges heat with the first structural member through the fan mount. Thus, when the fan module is in the extended position, at least a portion of the heat dissipation structure can be brought to the outside of the housing assembly, facilitating the thermal performance of the heat dissipation structure.

[0025] In some possible implementations, the housing assembly has a first vent and a second vent, both of which connect the fan mounting cavity to the outside of the housing assembly. When the fan module is in the inserted position, both the module inlet and outlet are located within the fan mounting cavity. One of the module inlet and outlet communicates with the first vent through the fan mounting cavity, while the other communicates with the second vent. This reduces the limitations imposed by the size of the fan module itself on airflow, facilitating larger airflow volumes. The connectivity of the first and second vents with the module inlet and outlet depends on the architectural design and is not limited in this application.

[0026] In some possible implementations, the housing assembly has a first vent that connects the fan mounting cavity to the outside of the housing assembly. When the fan module is in the inserted position, one of the module inlet and the module outlet is located within the fan mounting cavity and communicates with the first vent through the fan mounting cavity, while the other of the module inlet and outlet is located at the end of the fan module facing the outside of the housing assembly along a first direction. This allows for smoother airflow into and out of the fan mounting cavity, resulting in higher heat dissipation efficiency for the fan module. Furthermore, fewer openings on the housing assembly minimize the impact on its appearance. Additionally, reducing the number of openings on the first structural member and the need for air ducts formed by the first structural member simplifies its structure.

[0027] In some possible implementations, the fan module cover has a third vent and a fourth vent, one of which is a module air inlet and the other is a module air outlet. The fan of the fan module has a fan air inlet and a fan air outlet, one of which is connected to the outside of the housing assembly via the third vent. When the fan module is in the inserted position, the other of the fan air inlet and fan air outlet is located inside the fan mounting cavity, and the fourth vent connects the fan mounting cavity to the outside of the housing assembly. In this way, fresh air from outside the housing assembly can displace the air inside the fan mounting cavity through the third and fourth vents, thereby dissipating heat from the mobile terminal. Furthermore, vents may not be required on the housing assembly, thus not affecting its appearance. Additionally, reducing the openings on the first structural member and the need for air ducts formed by the first structural member can simplify the structure of the first structural member and also help reduce the thickness of the mobile terminal.

[0028] In some possible implementations, the fan module cover has a third vent and a fourth vent, one of which is a module air inlet and the other is a module air outlet. The fan assembly of the fan module also includes a second structural member fixedly mounted on the fan base. The second structural member forms a module air duct, and the third vent connects the outer side of the housing assembly to the module air duct. The fan of the fan module has a fan air inlet and a fan air outlet. One of the fan air inlet and the fan air outlet connects to the third vent via the module air duct, and the other of the fan air inlet and the fan air outlet connects to the outer side of the housing assembly via the fourth vent. The heat dissipation structure is disposed within the module air duct. Thus, fresh air from the outside of the housing assembly can displace the air in the module air duct through the third and fourth vents, thereby dissipating heat from the mobile terminal. Furthermore, vents may not be required on the housing assembly, thus not affecting its appearance. In addition, reducing the openings on the first structural component and the need for air ducts formed by the first structural component can simplify the structure of the first structural component and help reduce the thickness of the mobile terminal. Furthermore, when the fan module is in the extended position, the operating fan can continuously dissipate heat.

[0029] In some possible implementations, the fan module is a piezoelectric fan module with a small air volume and high pressure head. The fan module's air inlet and outlet are equipped with a dustproof structure featuring a waterproof and breathable membrane. This allows for a thinner fan module, facilitating its installation on mobile terminals. Furthermore, the flexible airflow direction of the piezoelectric fan allows for more flexible arrangement of the fan module. Additionally, the waterproof and breathable membrane dustproof structure ensures the long-term reliable operation of the dust-sensitive piezoelectric fan.

[0030] In some possible implementations, the housing assembly includes a housing and a decorative element. The decorative element is fixedly connected to the housing and protrudes from the outer surface of the housing. A first structural member is disposed within the decorative element and fixedly mounted on the inner wall of the decorative element. The first structural member and the decorative element together form a fan mounting cavity, and the decorative element has a fan inlet. In this way, the fan module does not occupy space within the housing, which is beneficial for the arrangement of components within the housing, and is especially suitable for ultra-thin mobile phones such as foldable phones.

[0031] In some possible implementations, a locking mechanism is provided on the first structural member. When the mobile terminal is in the fan-locked state, the locking mechanism locks the fan module to the first structural member. When the mobile terminal is in the fan-unlocked state, the locking mechanism releases the fan module from the first structural member. This simplifies the installation of the locking mechanism. Furthermore, when the fan module extends beyond the outer side of the housing assembly, the locking mechanism is less likely to be damaged due to exposure.

[0032] In some possible implementations, an anti-detachment structure is fixedly provided on the fan module. This anti-detachment structure is located within the fan mounting cavity and abuts against the inner wall of the housing assembly when the fan module is in the extended position, preventing the fan module inserted into the fan mounting cavity from detaching from the housing assembly through the fan connector. This facilitates keeping the fan module partially extended from and connected to the housing assembly, enabling heat dissipation of the mobile terminal through the partially extended fan module.

[0033] In some possible implementations, a push-out mechanism is also provided within the housing assembly. At least a portion of the push-out mechanism is located within the fan mounting cavity. The push-out mechanism is used to push a portion of the fan module, which is in the inserted position, out through the fan port to the outside of the housing assembly. This facilitates the extension of the fan module from within the fan mounting cavity.

[0034] The mobile terminal provided in this application embodiment can significantly improve the reliability and lifespan of the fan module, which is a bottleneck for the overall reliability of the device, through routine maintenance and simple repair of the fan module. This supports the use of the device with high performance and high system reliability, removes the constraints of fan lifespan and reliability on the application of mobile terminals, and achieves active heat dissipation for mobile phone products that is far superior to natural heat dissipation.

[0087] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0088] This application provides a mobile terminal, which may include, but is not limited to, mobile phones, tablets, ultra-mobile personal computers (UMPCs), handheld computers, walkie-talkies, netbooks, point-of-sale (POS) machines, personal digital assistants (PDAs), wearable devices, virtual reality devices, etc. This application uses a mobile phone as an example for illustration.

[0089] Figure 1 This is a schematic diagram of a mobile terminal provided in an embodiment of this application.

[0090] like Figure 1 As shown in the embodiments of this application, the mobile terminal may include a housing assembly 1 and a display screen 2. The display screen 2 is disposed on the housing assembly 1, and the housing assembly 1 has a cavity for setting devices.

[0091] The housing assembly 1 includes a housing 10, a display screen 2 disposed on one side of the housing 10 in the thickness direction, and a first chamber 30 may be present inside the housing 10. The display screen 2 can be used to cover the opening of the first chamber 30 on the thickness direction side of the housing 10. The first chamber 30 can be used to house the motherboard 3 (e.g., Figure 4 As shown), battery 4 (as shown) Figure 4 As shown), chip 6 (as shown) Figure 27 (as shown in the image) and other devices.

[0092] The housing 10 may include a middle frame (not shown), a side 11, and a rear cover 12. The side 11 is fixedly disposed on the edge of the middle frame. The display screen 2 is disposed on one side of the side 11 in the thickness direction of the middle frame. The rear cover 12 covers the other side of the side 11 in the thickness direction of the middle frame. The side 11 and the rear cover 12 are used to enclose and form a first chamber 30 (e.g., Figure 4 (as shown in the image).

[0093] In some examples, the middle frame and the side 11 are a single structure.

[0094] In other examples, the middle frame and the side 11 are separate structures, and the side 11 and the middle frame can be connected by nano-injection molding.

[0095] For example, the display screen 2 can be attached to the side 11.

[0096] For example, the back cover 12 can be disposed on the side 11 by at least one method such as adhesive bonding, fastener connection, snap-fit, etc.

[0097] In some examples, the mobile terminal can be a non-foldable device, for example, a candybar phone. In this case, the housing assembly 1 includes a housing 10.

[0098] Figure 2 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0099] like Figure 2 As shown, in other examples, the mobile terminal can be a foldable device, for example, a foldable phone. The housing assembly 1 can include multiple housings 10, with a hinge mechanism (not shown) between adjacent housings 10, allowing them to be rotatably connected. Specifically, the mid-frames 11 of adjacent housings 10 can be rotatably connected via the hinge mechanism. When the mobile terminal is a foldable device, the display screen 2 can be a flexible screen, which can be attached to the multiple housings 10. When the foldable device is in the unfolded state, the flexible screen can be located on the same side of the thickness direction of the attached housings 10.

[0100] When the mobile terminal is a foldable device, each housing 10 may have a first chamber 30. The motherboard 3 and the battery 4 may be respectively disposed in the first chambers 30 of two different housings 10.

[0101] Figure 3 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0102] like Figure 3As shown, in some examples, the housing assembly 1 also includes a decorative element 20, which is fixedly attached to the side of the housing 10 opposite to the display screen 2. Specifically, the decorative element 20 may be fixedly attached to the back cover 12. The decorative element 20 protrudes from the outer surface of the housing 10 and has a second chamber 40 (e.g., Figure 6 As shown in the figure, the second chamber 40 can be used to set up a camera, display device (such as a time display device, ultraviolet radiation display device), etc., and the second chamber 40 in the decorative piece 20 can be connected to the first chamber 30 in the housing 10 where the decorative piece 20 is located.

[0103] When the housing assembly 1 includes a plurality of housings 10, a decorative element 20 may be fixedly connected to one of the housings 10.

[0104] To improve the heat dissipation performance of the mobile terminal, the mobile terminal also includes a fan module 200 for active air cooling (e.g., Figure 4 As shown in the diagram, the fan module 200 can be housed within the housing assembly.

[0105] After a period of use, the fan module 200 is prone to problems such as dust accumulation and damage. When problems such as dust accumulation and damage occur, the fan module 200 needs to be routinely maintained (such as cleaning) or repaired.

[0106] In related technologies, the fan module is located in the first cavity of the housing. Repairing the fan module requires first removing the display screen or back cover from the side to expose it. However, removing the display screen or back cover can easily damage the seal between the side and the display screen or back cover. After repairing the fan module, it is often necessary to reseal it. Fan module repair is costly and difficult, potentially leading to the complete failure of the mobile terminal. Furthermore, removing the display screen or back cover to repair the fan module in the first cavity can also damage other components or devices such as the housing, side buttons, display screen, and battery, rendering them unusable. The cost of the fan module is far lower than that of the display screen, chip, and battery, and repairing these components after they fail is costly. Therefore, mobile terminals in these technologies are inconvenient to repair and difficult to maintain routinely.

[0107] Figure 4 This is a schematic diagram showing a fan module of a mobile terminal in the inserted position, provided in an embodiment of this application. Figure 5 for Figure 4The diagram provided shows the fan module of the mobile terminal in the extended position. In the diagram, the x-direction is the first direction, which is the insertion / removal direction of the fan module 200.

[0108] like Figure 4 As shown, based on this, in this embodiment of the application, the mobile terminal further includes a first structural member 100, which is fixedly disposed on the inner wall of the housing assembly 1. The first structural member 100 and the housing assembly 1 surround to form a fan mounting cavity 110. The housing assembly 1 has a fan socket 50 that connects the fan mounting cavity 110 and the outside of the housing assembly 1, and the fan module 200 is inserted into the fan mounting cavity 110 through the fan socket 50.

[0109] The mobile terminal has a fan-locked state and a fan-unlocked state. When the mobile terminal is in the fan-locked state, the fan module 200 is locked and fixed to the first structural member 100. When the mobile terminal is in the fan-unlocked state, the fan module 200 is released from the first structural member 100, and the fan module 200 can move along a first direction between an insertion position and an extension position, so that at least a portion of the fan module 200 can extend out of the housing assembly 1 through the fan connector 50, or at least a portion of the fan module 200 can be inserted back into the fan mounting cavity 110 through the fan connector 50. Specifically, when the fan module 200 moves from the insertion position to the extension position, at least a portion of the fan module 200 extends out of the housing assembly 1 through the fan connector 50; when the fan module 200 moves from the extension position to the insertion position, at least a portion of the fan module 200 is inserted back into the fan mounting cavity 110 through the fan connector 50.

[0110] In this way, when maintenance or repair of the fan module 200 is required, at least a portion of the fan module 200 can extend to the outside of the housing assembly 1 through the fan connector 50, facilitating dust removal, cleaning, or other maintenance, or repair and replacement work. After maintenance or repair, the fan module 200 can be reinserted into the fan mounting cavity 110 through the fan connector 50. Repairing the fan module 200 does not require disassembling the display screen 2, side panel 11, and back cover 12, thus minimizing the risk of damaging the seal between the display screen 2, side panel 11, and back cover 12. Furthermore, after maintenance or repair, there is no need to reseal the display screen 2, side panel 11, and back cover 12. The maintenance or repair cost of the fan module 200 is low, the operation is simple, and it is less likely to cause the entire mobile terminal to become unusable. In addition, when repairing the fan module 200 extending to the outside of the housing assembly 1, the repair tools do not need to be inserted into the housing assembly 1, minimizing the risk of damaging other components or devices of the mobile terminal, and reducing repair costs. The mobile terminal provided in this application embodiment makes it convenient to maintain or repair the fan module 200. Furthermore, by setting the first structural member 100 to form a fan mounting cavity 110 for inserting the fan module 200, it is easy to lock and securely connect the fan module 200 to the housing assembly 1. When the mobile terminal is in the fan-locked state, the fan module 200 and housing assembly 1 are locked and secured more securely, which helps maintain the performance of the fan module 200. When the mobile terminal is in the fan-unlocked state, the fan module 200 can move more stably along the first direction, making it easy to operate. The process of extending and inserting the fan module 200 is less likely to damage the entire device.

[0111] The first direction can be the length, width, or thickness of the mobile terminal.

[0112] When the mobile terminal is a foldable device, the length direction of the mobile terminal is the same as the length direction when the mobile terminal is in the unfolded state, the width direction of the mobile terminal is the same as the width direction when the mobile terminal is in the unfolded state, and the thickness direction of the mobile terminal is the same as the thickness direction when the mobile terminal is in the unfolded state.

[0113] When the mobile terminal is in the fan unlocked state, the fan module 200 can slide and engage with the cavity wall of the fan mounting cavity 110.

[0114] In some examples, when the fan module 200 is in the inserted position, the fan module 200 can be fully housed within the fan mounting cavity 110.

[0115] In other examples, when the fan module 200 is in the inserted position, the fan module 200 is partially housed within the fan mounting cavity 110 and partially extends to the outside of the housing assembly 1 through the fan connector 50. This facilitates the removal of the fan module 200 from the inserted position through the fan connector 50.

[0116] The extension position can be determined according to actual needs. For example, when the fan module 200 is in the extended position, it can extend one-third, one-half, two-thirds, three-quarters, four-fifths, or all of its length in the first direction to the outside of the housing assembly 1.

[0117] The first chamber 30 includes a first device mounting cavity 31. The mobile terminal's motherboard 3, battery 4, chip 6 and other devices are disposed in the first device mounting cavity 31. The battery 4 can be electrically connected to the motherboard 3. The chip 6 can be disposed on the motherboard 3 and electrically connected to the motherboard 3. The display screen 2 can be used to cover the opening of the first device mounting cavity 31 on the thickness side of the housing 10.

[0118] For example, one or more chips 6 can be set on the motherboard 3.

[0119] For example, motherboard 3 can be equipped with system-on-a-chip (SOC) chips, power management unit (PMU) chips, etc.

[0120] We can call devices that generate a lot of heat during operation "heat-generating devices". Mobile terminals include heat-generating devices, which may include, but are not limited to, motherboards, batteries, chips, cameras, etc.

[0121] In some examples, the first structural member 100 is disposed within the housing 10. Specifically, the first structural member 100 is located within the first chamber 30 and is fixedly mounted on the inner wall of the housing 10. The first structural member 100 and the housing 10 together form a fan mounting cavity 110, and the housing 10 has a fan inlet 50. In this case, the first chamber 30 includes the fan mounting cavity 110 and the first device mounting cavity 31, with the first device mounting cavity 31 located outside the fan mounting cavity 110.

[0122] In this way, the distance between the fan module 200 and the heat-generating device disposed in the first device mounting cavity 31 is relatively small, which can make the heat dissipation effect of the fan module 200 better.

[0123] When the first structural member 100 is fixedly disposed on the inner wall of the housing 10, the first structural member 100 can be fixedly connected to at least one of the side 11 and the rear cover 12.

[0124] Figure 6 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0125] like Figure 6As shown, in the example where the housing assembly 1 includes the decorative element 20, the second chamber 40 may include a second device mounting cavity 41, in which devices such as cameras may be disposed. The second device mounting cavity 41 may communicate with the first device mounting cavity 31, and the cameras and other devices disposed in the second device mounting cavity 41 may be electrically connected to the motherboard 3.

[0126] In some examples where the housing assembly 1 includes a decorative element 20, a first structural element 100 may be disposed within the decorative element 20. Specifically, the first structural element 100 is located within the second chamber 40 and is fixedly disposed on the inner wall of the decorative element 20. The first structural element 100 and the decorative element 20 enclose a fan mounting cavity 110, and the decorative element 20 has a fan inlet 50.

[0127] In this way, the fan module 200 does not occupy space within the housing 10, which facilitates the arrangement of components within the housing 10. Furthermore, the high performance of the fan module 200 requires sufficient thickness and air intake space, which directly conflicts with the slim and lightweight design of mobile terminals, especially the aesthetic requirements of foldable devices. By placing the first structural component 100 and the fan module 200 within the decorative component 20, the contradiction between the ultra-thin appearance and the high-performance application of the fan module 200 can be resolved.

[0128] In some examples where the housing assembly 1 includes the trim 20, the second chamber 40 includes a fan mounting cavity 110 and a second device mounting cavity 41 located outside the fan mounting cavity 110.

[0129] In some other examples where the housing assembly 1 includes the decorative element 20, the decorative element 20 may also be a decorative element 20 used solely for setting the fan module 200, meaning that other devices such as cameras and display devices may not be installed in the second chamber 40.

[0130] In some examples, the orientation of the fan port 50 can be perpendicular to the thickness direction of the mobile terminal; that is, the first direction can be perpendicular to the thickness direction of the mobile terminal. For example, the first direction can be the length direction or the width direction of the mobile terminal.

[0131] Figure 7 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0132] like Figure 7 As shown, in some examples, the orientation of the fan port 50 can be perpendicular to the thickness direction of the mobile terminal and inclined to the length and width directions of the mobile terminal. That is, the first direction can be perpendicular to the thickness direction of the mobile terminal and inclined to the length and width directions of the mobile terminal.

[0133] In some examples, the cross-sectional dimension of the end of the fan mounting cavity 110 away from the fan connector 50 is smaller than the dimension of the fan connector 50. This allows the cavity wall of the fan mounting cavity 110 to limit the depth to which the fan module 200 is inserted into the fan mounting cavity 110. For example, the cross-sectional dimension of the fan mounting cavity 110 can gradually decrease from the end connected to the fan connector 50 to the end away from the fan connector 50, and the shape of the fan module 200 matches the fan mounting cavity 110. The cross-section of the fan mounting cavity 110 refers to the section of the fan mounting cavity 110 perpendicular to the first direction.

[0134] Figure 8 This is a schematic diagram from another perspective of a mobile terminal provided in an embodiment of this application. Figure 9 for Figure 8 This is another schematic diagram of the provided mobile terminal. Figure 8 , 9 After the fan module 200 is removed along the x-direction, the exposed surface of the first structural member 100 that comes into contact with the fan module 200 is the inner wall of the first structural member 100.

[0135] like Figure 8 , Figure 9 As shown, in some examples, the orientation of the fan port 50 can be the thickness direction of the mobile terminal, that is, the first direction is the thickness direction of the mobile terminal.

[0136] Figure 10 This is a schematic diagram of a mobile terminal in a fan-locked state and the fan module in an inserted position, provided as an embodiment of this application, from a second direction perspective. Figure 11 for Figure 10 The diagram provided illustrates the second direction side of a mobile terminal with the fan unlocked and the fan module in the extended position. In the diagram, the z-direction is the third direction, the second direction is perpendicular to the first direction, the third direction is perpendicular to the first direction, and the second direction is perpendicular to the third direction.

[0137] like Figure 10 , Figure 11 As shown, in some possible embodiments, a locking mechanism 300 is provided on the first structural member 100. When the mobile terminal is in the fan-locked state, the locking mechanism 300 locks the fan module 200 to the first structural member 100. When the mobile terminal is in the fan-unlocked state, the locking mechanism 300 releases the fan module 200 from the first structural member 100.

[0138] This makes the installation of the locking mechanism 300 easier. Furthermore, when the fan module 200 extends beyond the outer side of the housing assembly 1, the locking mechanism 300 is less likely to be damaged due to exposure.

[0139] In some examples, the locking mechanism 300 includes a latch 310, a connecting rod 320, a rotating rod 330, a rotating shaft 340, and a first spring 350. One end of the connecting rod 320 is fixedly connected to the latch 310, and the other end of the connecting rod 320 is fixedly connected to one end of the rotating rod 330. The rotating shaft 340 is located between the two ends of the rotating rod 330, and both ends of the rotating shaft 340 extend along a second direction. The rotating rod 330 is rotatably connected to the first structural member 100 through the rotating shaft 340, and the rotating rod 330 is connected to the first structural member 100 through the first spring 350. The fan module 200 has a locking groove 223 on its third-direction side that mates with the latch 310. When the mobile terminal is in the fan-locked state, the latch 310 is in the locked position and inserted into the locking groove 223, so that the fan module 200 is locked and fixed to the first structural member 100. When the mobile terminal is in the fan unlocked state, the locking tongue 310 rotates around the pivot 340 to the unlocked position outside the locking groove 223, thereby releasing the fan module 200 from the first structural member 100. The first spring 350 is used to drive the locking tongue 310, which is in the unlocked position, to rotate to the locked position.

[0140] The fan module 200 includes an insertion end (not shown), which is one end of the fan module 200 facing the fan mounting cavity 110 away from the fan socket 50.

[0141] For example, during the process of the fan module 200 moving from the extended position to the inserted position, the portion of the inserted end that abuts against the latch 310 located in the locked position is a bevel, so as to push the latch 310 to rotate from the locked position to the unlocked position, so that when the locking groove 223 moves to the latch 310, the latch 310 can be inserted into the locking groove 223.

[0142] For example, during the process of the fan module 200 moving from the extended position to the inserted position, the portion of the locking tongue 310 in the locked position that abuts against the inserted end is an arc surface, so that the inserted end can push the locking tongue 310 from the locked position to the unlocked position during the process of the fan module 200 moving from the extended position to the inserted position.

[0143] In some examples where a locking mechanism 300 is provided on the first structural member 100, an unlocking mechanism 500 is also provided on the first structural member 100. The unlocking mechanism 500 is connected to the locking mechanism 300 in a transmission manner. The unlocking mechanism 500 is used to switch the mobile terminal from the fan locked state to the fan unlocked state after receiving an unlocking signal.

[0144] In some examples where the locking mechanism 300 includes a locking tongue 310, a connecting rod 320, a rotating rod 330, a rotating shaft 340, and a first spring 350, the unlocking mechanism 500 may include a push rod 510 extending at both ends along a first direction. A push rod slide rail 120 extending at both ends along the first direction is provided within the first structural member 100. The push rod 510 is slidably fitted within the push rod slide rail 120. The housing assembly 1 has a first insertion hole 60 communicating with the push rod slide rail 120 and the outside of the housing assembly 1. One end of the push rod 510 is used to abut against the end of the rotating rod 330 away from the connecting rod 320, and the other end of the push rod 510 is opposite to the first socket 60. The first socket 60 allows the pin to pass through. After the pin passes through the first socket 60, it can push the push rod 510 to slide, so as to apply an unlocking signal to the push rod 510. The push rod 510 pushed by the pin can push the rotating rod 330 to rotate, so as to rotate the locking tongue 310 from the locked position to the unlocked position, thereby enabling the mobile terminal to switch from the fan locked state to the fan unlocked state.

[0145] For example, a resilient seal 61 is provided within the first insertion hole 60. The resilient seal 61 has a connecting hole through which a pin can pass. When no pin is inserted into the connecting hole, the resilient seal 61 presses against the wall of the connecting hole to seal it. When the pin is inserted into the first insertion hole 60, the resilient seal 61 deforms under the force of the pin, causing the connecting hole to open and allowing the pin to pass through. When the pin is inserted into the connecting hole, the wall of the connecting hole presses against the side wall of the pin to seal it. This prevents damage to the sealing performance of the housing assembly 1 due to the opening of the first insertion hole 60.

[0146] In some possible implementations, a push-out mechanism 400 is also provided within the housing assembly 1. At least a portion of the push-out mechanism 400 is located within the fan mounting cavity 110. The push-out mechanism 400 is used to push a portion of the fan module 200 in the inserted position outward through the fan socket 50 to the outside of the housing assembly 1.

[0147] This facilitates the extension of the fan module 200 from the fan mounting cavity 110. By using the ejection mechanism 400 to eject the fan module 200, the fan module 200 can be ejected without manual pulling, providing a good automatic pop-out user experience and reliability.

[0148] For example, the ejection mechanism 400 may include a second spring 410, one end of which is connected to the first structural member 100, and the other end of which is used to abut against the fan module 200. Specifically, the second spring 410 is used to abut against the insertion end. When the mobile terminal is in the fan-locked state, the second spring 410 is in a compressed state. When the mobile terminal is in the fan-unlocked state, the elastic restoring force generated by the second spring 410 is used to push a portion of the fan module 200 in the insertion position out through the fan socket 50 to the outside of the housing assembly 1.

[0149] For example, the ejection mechanism 400 may also include a push plate 420, one end of the second spring 410 is connected to the first structural member 100, and the other end of the second spring 410 is connected to the push plate 420. The second spring 410 is used to abut against the fan module 200 through the push plate 420, so that the second spring 410 pushes the fan module 200 more stably.

[0150] In some possible implementations, a position detection device 620 is also provided within the fan mounting cavity 110. The position detection device 620 is used to detect whether the fan module 200 is in the insertion position. The position detection device 620 can be electrically connected to the motherboard 3 via a cable, and further electrically connected to a controller (not shown) via the motherboard 3. The controller can acquire the detection information obtained by the position detection device 620 and determine whether the fan module 200 is in the insertion position based on this information. The controller can also issue a control command indicating that the fan module 200 is not in the insertion position when it is not in the insertion position. This control command can be used to control an audible and visual alarm, display screen 2, etc., to trigger an alarm.

[0151] For example, the position detection device 620 may include, but is not limited to, a distance sensor, a pressure sensor, etc.

[0152] When the position detection device 620 is a distance sensor, the position detection device 620 can be used to detect the distance between the fan module 200 and the position detection device 620.

[0153] When the position detection device 620 is a pressure sensor, the fan module 200 in the insertion position is used to apply pressure to the pressure sensor. Specifically, when the ejection mechanism 400 includes a push plate 420, the fan module 200 in the insertion position can be used to apply pressure to the pressure sensor through the push plate 420. In the first direction, the push plate 420 is located between the fan module 200 and the pressure sensor. When the fan module 200 is in the insertion position, one side of the push plate 420 abuts against the fan module 200, and the other side of the push plate 420 abuts against the pressure sensor.

[0154] In some possible implementations, the fan module 200 includes a cover plate 210 and a fan assembly 220, which can be used for active air cooling of the mobile terminal. The cover plate 210 is fixedly disposed at one end of the fan assembly 220 in a first direction. The fan assembly 220 is inserted into the fan mounting cavity 110 through a fan connector 50, and the cover plate 210 is located on the outside of the housing assembly 1. When the fan module 200 is in the inserted position, the cover plate 210 covers the outer surface of the housing assembly 1, and the orthographic projection of the cover plate 210 on the outer surface of the housing assembly 1 covers the edge of the housing assembly 1 at the fan connector 50. When the fan module 200 moves along the first direction between the inserted position and the extended position, at least a portion of the fan assembly 220 extends outward through the fan connector 50 to the outside of the housing assembly 1, or at least a portion of the fan assembly 220 is inserted back into the fan mounting cavity 110 through the fan connector 50.

[0155] In this way, the cover plate 210 can limit the depth to which the fan module 200 is inserted into the fan mounting cavity 110.

[0156] In some examples where the housing assembly 1 has a first socket 60 for inserting a pin, the cover plate 210 has a second socket 211 opposite to the first socket 60, through which the pin can extend into the push rod slide 120 to push the push rod 510.

[0157] In some possible implementations, the mobile terminal further includes a first sealing ring 610, which is disposed between the cover plate 210 and the outer surface of the housing assembly 1, and surrounds the fan socket 50 circumferentially. When the fan module 200 is in the inserted position, the first sealing ring 610 is pressed together by the cover plate 210 and the outer surface of the housing assembly 1, thereby sealing the fan module 200 and the housing assembly 1 at the fan socket 50.

[0158] In this way, when the fan module 200 is in the insertion position, the sealing performance of the housing assembly 1 is not easily damaged by opening the fan port 50, so that the mobile terminal has better sealing performance.

[0159] The fan module 200 can come with waterproof and dustproof components.

[0160] In some examples, the waterproof and dustproof components of the fan module 200 may include a first sealing ring 610, which may be fixedly mounted on the cover plate 210.

[0161] This makes it easier to plug and unplug the fan assembly 220 at the fan connector 50.

[0162] In other examples, the first sealing ring 610 may be fixedly mounted on the housing assembly 1.

[0163] Figure 12 This is a schematic diagram of a second direction side of a mobile terminal in a fan-locked state and with the fan module in the insertion position, as provided in an embodiment of this application.

[0164] like Figure 12 As shown, in some examples where the locking mechanism 300 includes a locking tongue 310, a connecting rod 320, a rotating rod 330, a rotating shaft 340, and a first spring 350, the unlocking mechanism 500 includes a push rod 510 extending at both ends along a first direction. A push rod slide 120 extending at both ends along the first direction is provided within the first structural member 100. The push rod 510 is slidably fitted within the push rod slide 120. The housing assembly 1 has a first insertion hole 60 communicating with the push rod slide 120 and the outside of the housing assembly 1. The unlocking mechanism 500 also includes a button 520 disposed within the first insertion hole 60. One end of the push rod 510 is used to abut against the end of the rotating rod 330 away from the connecting rod 320, and the other end of the push rod 510 is fixedly connected to the button 520. Users can apply an unlock signal to button 520 by pressing button 520. The pressed button 520 can push push rod 510 to slide, and push rod 510 pushed by button 520 can push rotating rod 330 to rotate, so as to rotate the locking tongue 310 from the locked position to the unlocked position, thereby allowing the mobile terminal to switch from the fan locked state to the fan unlocked state.

[0165] Figure 13 This is a schematic diagram of a second direction side of a mobile terminal in a fan-locked state and with the fan module in the insertion position, as provided in an embodiment of this application.

[0166] like Figure 13 As shown, in some examples where the locking mechanism 300 includes a latch 310, a connecting rod 320, a rotating rod 330, a rotating shaft 340, and a first spring 350, the unlocking mechanism 500 includes an electromagnet 530 and a magnetic element 540. The electromagnet 530 is fixedly connected to the first structural member 100, and the magnetic element 540 is fixedly disposed at the end of the rotating rod 330 away from the connecting rod 320. When the mobile terminal is in the fan 221 locked state, the electromagnet 530 is de-energized and attracts the magnetic element 540. The user applies an unlocking signal to the electromagnet 530 by energizing it. The energized electromagnet 530 generates a magnetic repulsive force that pushes the magnetic element 540 away. The magnetic element 540, pushed away by the magnetic repulsive force generated by the electromagnet 530, drives the rotating rod 330 to rotate, thereby rotating the latch 310 from the locked position to the unlocked position, thus allowing the mobile terminal to switch from the fan locked state to the fan unlocked state.

[0167] Figure 14 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0168] like Figure 14As shown, in some examples, the locking mechanism 300 is an elastic locking mechanism 300. The locking mechanism 300 deforms under the action of an unlocking force, thereby switching the mobile terminal from a fan-locked state to a fan-unlocked state. The unlocking force is the force exerted by the fan module 200 moving along the first direction on the locking mechanism 300. This unlocking force is greater than the elastic restoring force generated by the locking mechanism 300 when it deforms to unlock the fan module 200 from the first structural member 100. Thus, no special unlocking operation is required when inserting or removing the fan module 200, making insertion and removal of the fan module 200 more convenient.

[0169] In some examples where the locking mechanism 300 is an elastic locking mechanism 300, the locking mechanism 300 includes an elastic locking component 360. A locking ball slide 130 corresponding to the elastic locking component 360 is provided on the first structural member 100. One end of the locking ball slide 130 communicates with the fan mounting cavity 110, and the other end of the locking ball slide 130 is a sealed structure. The elastic locking component 360 includes a third spring 362 and a locking ball 361. The locking ball 361 of the elastic locking component 360 slides... The third spring 362 of the elastic locking assembly 360 is fitted into the corresponding ball-locking slide 130. One end of the spring 362 abuts against the end of the corresponding ball-locking slide 130 away from the fan mounting cavity 110, and the other end abuts against the locking ball 361. A limit ring (not shown) is provided at one end of the ball-locking slide 130 that connects to the fan mounting cavity 110. A portion of the locking ball 361 can pass through the limit ring and extend into the fan mounting cavity 110. The limit ring is used to prevent the locking ball 361 from dislodging from the ball-locking slide 130. The fan mounting cavity 110 is provided with the elastic locking assembly 360 on at least one side in the third direction. The fan module 200 is provided with a locking groove 223 corresponding to the elastic locking assembly 360 on the side in the third direction.

[0170] When the mobile terminal is in the fan-locked state, a portion of the locking ball 361 of the elastic locking assembly 360 is located within the fan mounting cavity 110 and extends into the corresponding locking groove 223 to lock and fix the fan module 200 to the first structural member 100. Under the action of the unlocking force, the locking ball 361 compresses the third spring 362, causing at least a portion of the locking ball 361 to retract into the corresponding locking ball slide 130, thereby moving out of the corresponding locking groove 223 and switching the mobile terminal from the fan-locked state to the fan-unlocked state. During the process of the fan module 200 moving from the extended position to the inserted position, the third spring 362 is first compressed, causing at least a portion of the locking ball 361 to retract into the corresponding locking ball slide 130. After the fan module 200 moves to the inserted position, a portion of the locking ball 361 moves into the fan mounting cavity 110 under the action of the elastic restoring force of the third spring 362 and extends into the corresponding locking groove 223.

[0171] In some examples, the resilient locking assembly 360 also includes a ball seat 363, which is disposed between the third spring 362 and the locking ball 361. The ball seat 363 can be fixedly connected to the third spring 362, and the ball seat 363 is slidably engaged with the locking ball slide 130. The third spring 362 abuts against the locking ball 361 through the ball seat 363. In this way, the locking ball 361 can slide more stably within the locking ball slide 130.

[0172] Figure 15 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0173] like Figure 15 As shown, in some examples where the locking mechanism 300 is an elastic locking mechanism 300, the locking mechanism 300 includes a locking spring 370, and the inner wall of the first structural member 100 is provided with a spring groove 140 corresponding to the locking spring 370. The locking spring 370 includes a spring arm section 371 and a locking section 372. The spring arm section 371 is located in the corresponding spring groove 140. One end of the spring arm section 371 is fixedly connected to the groove wall of the corresponding spring groove 140 on the side away from the fan inlet 50 in the first direction, and the other end of the spring arm section 371 is fixedly connected to the locking section 372. The fan mounting cavity 110 is provided with a locking spring 370 on at least one side in the third direction, and the fan module 200 is provided with a locking groove 223 corresponding to the locking spring 370 on the side in the third direction.

[0174] When the mobile terminal is in the fan-locked state, the locking section 372 of the locking spring 370 is located inside the fan mounting cavity 110 and extends into the corresponding locking groove 223 to lock and fix the fan module 200 to the first structural member 100. Under the action of the unlocking force, the locking section 372 will cause the spring arm section 371 to deform in a third direction away from the fan module 200, causing the locking section 372 to move out of the corresponding locking groove 223, thereby switching the mobile terminal from the fan-locked state to the fan-unlocked state. During the process of moving the fan module 200 from the extended position to the inserted position, the spring arm section 371 will first deform in a third direction away from the fan module 200, so that at least part of the locking section 372 retracts into the corresponding spring slot 140. After the fan module 200 moves to the inserted position, part of the locking section 372 will move into the fan mounting cavity 110 under the action of the elastic restoring force of the spring arm section 371 and extend into the corresponding locking groove 223.

[0175] For example, the locking section 372 has a beveled structure on both the side near the fan socket 50 and the side away from the fan socket 50, so as to facilitate movement in a third direction under the abutment of the fan module 200 moving in the first direction.

[0176] Figure 16 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0177] In some examples where the locking mechanism 300 is an elastic locking mechanism 300, the ejection mechanism 400 includes an electrically operated telescopic rod 430, with both ends of the electric telescopic rod 430 extending along a first direction. One end of the electric telescopic rod 430 is fixedly connected to the first structural member 100, and the other end of the electric telescopic rod 430 is used to abut against the insertion end of the fan module 200. The electric telescopic rod 430 can be electrically connected to the motherboard 3. Upon receiving an ejection signal, the electric telescopic rod 430 extends to apply an unlocking force to the locking mechanism 300 and eject a portion of the fan module 200 to the outside of the housing assembly 1.

[0178] The electric telescopic pole 430 can be electrically connected to the controller via the main board 3 and is controlled by the controller.

[0179] Figure 17 This is a schematic diagram showing the fan module of another mobile terminal in the inserted position, as provided in an embodiment of this application. Figure 18 for Figure 17 A schematic diagram showing the fan module of the provided mobile terminal in the extended position.

[0180] like Figure 17 , Figure 18 As shown, in some examples, the first structural member 100 has a slider track 150 extending at both ends along a first direction, and the ejection mechanism 400 includes a slider 440 and a second spring 410. The slider 440 is slidably engaged with the slider track 150, and the two ends of the second spring 410 extend along the first direction. The end of the second spring 410 near the fan port 50 abuts against the slider 440, and the end of the second spring 410 away from the fan port 50 abuts against the first structural member 100. The slider 440 is fixedly connected to the fan module 200.

[0181] The locking mechanism 300 includes a pull rod 380, which comprises a connecting section 381, a first insertion section 382, ​​and a second insertion section 383. The two ends of the connecting section 381 are spaced apart in a first direction. One end of the connecting section 381 is fixedly connected to one end of the first insertion section 382, ​​and the other end of the connecting section 381 is fixedly connected to one end of the second insertion section 383. Both the first insertion section 382 and the second insertion section 383 are straight rods extending in a second direction at both ends. The slider 440 has a groove 390 on one side of the surface in the second direction. The end of the second insertion section 383 away from the connecting section 381 is inserted into the groove 390 and slides within it, allowing the second insertion section 383 to slide along the groove 390.

[0182] The slide 390 includes a first groove segment 391, a second groove segment 392, a third groove segment 393, a fourth groove segment 394, and a fifth groove segment 395. The first groove segment 391 is a straight groove extending at both ends along a first direction. The end of the first groove segment 391 away from the fan inlet 50 is a sealed end. The second groove segment 392, the third groove segment 393, the fourth groove segment 394, and the fifth groove segment 395 are all arc-shaped grooves.

[0183] In the first direction, the end of the second slot 392 away from the fan socket 50 is connected to the end of the first slot 391 near the fan socket 50; the end of the second slot 392 near the fan socket 50 is connected to the end of the third slot 393 near the fan socket 50; the end of the third slot 393 away from the fan socket 50 is connected to the end of the fourth slot 394 away from the fan socket 50; the end of the fourth slot 394 near the fan socket 50 is connected to the end of the fifth slot 395 near the fan socket 50; and the end of the fifth slot 395 away from the fan socket 50 is connected to the end of the first slot 391 near the fan socket 50. The second slot 392, the third slot 393, the fourth slot 394, and the fifth slot 395 all have a concave arc structure on the side facing the fan socket 50 along the first direction.

[0184] Figure 19 for Figure 17 A schematic diagram of the sliding groove of the provided mobile terminal along the extension direction of the sliding groove.

[0185] like Figure 19 As shown, and see Figure 17 , Figure 18 A first step structure 396 is formed at the junction of the second groove segment 392 and the third groove segment 393. The first step structure 396 is used to prevent the second insertion segment 383, which has slid into the third groove segment 393, from sliding back to the second groove segment 392. A second step structure 397 is formed at the junction of the third groove segment 393 and the fourth groove segment 394. The second step structure 397 is used to prevent the second insertion segment 383, which has slid into the fourth groove segment 394, from sliding back to the third groove segment 393. A third step structure 398 is formed at the junction of the fourth groove segment 394 and the fifth groove segment 395. The third step structure 398 is used to prevent the second insertion segment 383, which has slid into the fifth groove segment 395, from sliding back to the fourth groove segment 394. A fourth step structure 399 is formed at the junction of the fifth groove segment 395 and the first groove segment 391. The fourth step structure 399 is used to prevent the second insertion segment 383, which has slid into the first groove segment 391 and the second groove segment 392, from sliding back to the fifth groove segment 395.

[0186] The second groove segment 392 has an inclined surface structure for allowing the second insertion segment 383 to slide from the end of the second groove segment 392 connected to the first groove segment 391 to the first step structure 396; the third groove segment 393 has an inclined surface structure for allowing the second insertion segment 383 to slide from the end of the third groove segment 393 connected to the second groove segment 392 to the second step structure 397; the fourth groove segment 394 has an inclined surface structure for allowing the second insertion segment 383 to slide from the end of the fourth groove segment 394 connected to the third groove segment 393 to the third step structure 398; and the fifth groove segment 395 has an inclined surface structure for allowing the second insertion segment 383 to slide from the end of the fifth groove segment 395 connected to the fourth groove segment 394 to the fourth step structure 399.

[0187] Figure 20 for Figure 17 A schematic diagram of the connection between the pull rod of the provided mobile terminal and the first structural component, in which the y-direction is the second direction.

[0188] like Figure 20 As shown, and see Figures 17-19 The first structural member 100 has a pressure plate slide 160 extending at both ends along the second direction. A pressure plate 384 is slidably assembled in the pressure plate slide 160. The first structural member 100 has a sliding hole communicating with the pressure plate slide 160. A first insertion section 382 is inserted into the sliding hole. The first insertion section 382 can slide relative to the first structural member 100 along the second direction. The first insertion section 382 is rotatably connected to the first structural member 100. The end of the first insertion section 382 away from the connecting section 381 is located in the pressure plate slide 160 and connected to the pressure plate 384. When the second insertion section 383 slides along the inclined structure in the slide groove 390, the first insertion section 382 will drive the pressure plate 384 to slide along the pressure plate channel 160. A fourth spring 385 is provided in the pressure plate slide 160. One end of the fourth spring 385 abuts against the side of the pressure plate 384 facing the sliding hole, and the other end of the fourth spring 385 abuts against the first structural member 100. The fourth spring 385 is used to keep the end of the second insertion section 383 away from the connecting section 381 in contact with the bottom of the slide groove 390.

[0189] When the mobile terminal is in the fan-locked state, the second insertion segment 383 is located in the fourth slot segment 394 and at one end of the fourth slot segment 394 connecting to the third slot segment 393. The fan module 200 is locked and fixed to the first structural member 100 by the pull rod 380 and the slider 440.

[0190] When it is necessary to move the fan module 200 from the inserted position to the extended position, the slider 440 can be moved by pressing the fan module 200 in the first direction. Due to the obstruction of the second step structure 397 and the third step structure 398, the second insertion segment 383 will slide along the fourth slot segment 394 into the fifth slot segment 395 and slide towards the first slot segment 391, so that the pull rod 380 is unlocked from the slider 440. The third spring 362 pushes the slider 440 to extend the fan module 200. The second insertion segment 383 can slide along the fifth slot segment 395 and the first slot segment 391 to the end of the first slot segment 391 away from the fan socket 50.

[0191] When it is necessary to move the fan module 200 from the extended position to the inserted position, the slider 440 can be moved by pressing the fan module 200 in the first direction. Due to the obstruction of the fourth step structure 399 and the first step structure 396, the second insertion segment 383 will slide along the first groove segment 391 and the second groove segment 392 into the third groove segment 393, and move along the third groove segment 393 to the fourth groove segment 394 to connect to one end of the third groove segment 393, thereby locking the fan module 200 in the inserted position.

[0192] For example, the end of the second insertion segment 383 away from the connecting segment 381 can be a ball-head structure so that the second insertion segment 383 can slide along the inclined plane.

[0193] In some other possible implementations, a locking mechanism 300 is provided on the fan module 200. When the mobile terminal is in the fan-locked state, the locking mechanism 300 locks the fan module 200 to the first structural member 100. When the mobile terminal is in the fan-unlocked state, the locking mechanism 300 releases the fan module 200 from the first structural member 100.

[0194] In some examples, when the mobile terminal is in the fan unlocked state, the fan module 200 can be completely pulled out from the fan socket 50, that is, the fan module 200 can be separated from the housing assembly 1.

[0195] Figure 21 This is a schematic diagram of a mobile terminal fan module in the extended position, as provided in another embodiment of this application.

[0196] like Figure 21As shown, in some other examples, when the mobile terminal is in the fan unlocked state, the fan module 200 cannot be completely pulled out from the fan socket 50. That is, the fan module 200 cannot be separated from the housing assembly 1, and part of the fan module 200 is always located within the fan mounting cavity 110. Specifically, an anti-detachment structure 630 can be fixedly provided on the fan module 200. The anti-detachment structure 630 is located within the fan mounting cavity 110. The anti-detachment structure 630 is used to abut against the inner wall of the housing assembly 1 when the fan module 200 is in the extended position, so as to prevent the fan module 200 inserted in the fan mounting cavity 110 from detaching from the housing assembly 1 through the fan socket 50.

[0197] This allows the fan module 200 to remain partially extended from and connected to the housing assembly 1, facilitating heat dissipation for the mobile terminal via the fan module 200 that partially extends from the housing assembly 1.

[0198] For example, the fan mounting cavity 110 has a groove structure (not shown) on its cavity wall for the anti-detachment structure 630 to slide along a first direction, and the anti-detachment structure 630 is inserted into the groove structure.

[0199] Figure 22 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0200] like Figure 22 As shown, the mobile terminal also includes a power supply device and an electrical connection device 5. The power supply device is disposed within the first device mounting cavity 31, and part of the electrical connection device 5 is located within the first device mounting cavity 31, while part is located within the fan mounting cavity 110.

[0201] In some examples, when the fan module 200 is in the inserted position, the fan module 200 is electrically connected to the power supply device via the electrical connection device 5.

[0202] In this way, power can be supplied to the fan module 200 when it is in the insertion position by a power supply device disposed in the first device mounting cavity 31, so as to drive the fan module 200 when it is in the insertion position. When the fan module 200 is in the insertion position, the overall drop resistance of the mobile terminal is good, and the appearance of the mobile terminal is not changed.

[0203] In some examples, when the fan module 200 is in the extended position, the fan module 200 is electrically connected to the power supply device via the electrical connection device 5.

[0204] In this way, power can be supplied to the fan module 200 in the extended position by a power supply device disposed in the first device mounting cavity 31, so as to drive the fan module 200 when it is in the inserted position. When the fan module 200 is in the extended position, the air intake resistance is small, the air intake volume is large, and the heat dissipation efficiency is high. In addition, when the fan module 200 in the extended position is operating for heat dissipation, the space inside the fan mounting cavity 110 is increased, which helps to reduce the flow pressure drop and flow resistance inside the fan mounting cavity 110, and can increase the pressure head of the fan module 200.

[0205] For heavy-load, high-performance applications, the fan module 200 can be manually or automatically ejected from the housing assembly 1 based on software temperature reporting. When the fan module 200 is in the extended position, it can operate, exposing the air intake of the fan module 200, which is located within the fan mounting cavity 110 when in the inserted position, to the atmosphere. This significantly increases the air intake area of ​​the fan module 200 while reducing airflow resistance, resulting in a significant performance improvement and enabling it to support high-load, high-power applications. After the fan module 200 retracts into the inserted position within the housing assembly 1, the mobile terminal exhibits improved overall drop resistance.

[0206] Power supply components may include, but are not limited to, motherboard 3, battery 4, controller, etc.

[0207] For example, the fan module 200 can be electrically connected to the motherboard 3 via the electrical connector 5, the battery 4 can supply power to the fan module 200 via the motherboard 3, and the controller can control the fan module 200 via the motherboard 3. In this way, the power supply and control of the fan module 200 are relatively convenient.

[0208] In some possible implementations, the electrical connection device 5 includes an electrical contact terminal 170 fixedly disposed on the first structural member 100, and the fan module 200 has a first electrical contact portion 224. The electrical contact terminal 170 includes a second electrical contact portion 171 located within the fan mounting cavity 110 and a connecting portion 172 located within the first device mounting cavity 31, the connecting portion 172 being electrically connected to the power supply device. The first electrical contact portion 224 is used to make electrical contact with the second electrical contact portion 171, so that the fan module 200 is electrically connected to the power supply device through the electrical contact terminal 170.

[0209] This facilitates the electrical connection between the fan module 200 and the power supply device. Furthermore, the electrical connection device 5 has minimal impact on the movement of the fan module 200.

[0210] In some examples, when the fan module 200 is in the inserted position, the first electrical contact 224 is located inside the fan mounting cavity 110 and makes electrical contact with the second electrical contact 171, and the fan module 200 is electrically connected to the power supply device through the electrical contact terminal 170.

[0211] This facilitates the electrical connection between the fan module 200 and the power supply device when the fan module 200 is in the inserted position.

[0212] In some examples, when the fan module 200 is in the extended position, the first electrical contact 224 is located inside the fan mounting cavity 110 and makes electrical contact with the second electrical contact 171, and the fan module 200 is electrically connected to the power supply device through the electrical contact terminal 170.

[0213] This facilitates the electrical connection between the fan module 200 and the power supply device when the fan module 200 is in the extended position.

[0214] Figure 23 This is a schematic diagram of a mobile terminal before the fan module is inserted into the fan mounting cavity, as provided in an embodiment of this application.

[0215] like Figure 23 As shown, in some examples, the first electrical contact 224 is located on one side of the surface of the fan module 200 in the second direction. The first electrical contact 224 can be a conductive contact structure, and the second electrical contact 171 can be a conductive spring structure.

[0216] In other examples, the insertion end of the fan module 200 has a plug interface, the first electrical contact 224 is a conductive spring structure disposed in the plug interface, and the second electrical contact 171 is a conductive pin structure disposed on the side of the fan mounting cavity 110 opposite to the fan socket 50. When the fan module 200 is in the insertion position, the conductive pin is inserted into the plug interface and makes electrical contact with the conductive spring structure in the plug interface.

[0217] In some examples, a second sealing ring (not shown) is provided on the edge of the connector. The waterproof and dustproof assembly of the fan module 200 may include the second sealing ring. When the fan module 200 is in the inserted position, the second sealing ring is pressed by the fan module 200 and the first structural member 100. The second sealing ring seals the fan module 200 and the first structural member 100 at the connector, so that the conductive spring structure in the connector and the electrically contacting conductive pin are in a sealed space.

[0218] For example, the electrical connection device 5 includes a plurality of electrical contact terminals 170, and the fan module 200 has a plurality of first electrical contact portions 224 corresponding one-to-one with the plurality of electrical contact terminals 170. The plurality of electrical contact terminals 170 include a positive terminal, a negative terminal, and a signal terminal. The plurality of first electrical contact portions 224 include a positive electrical contact portion, a negative electrical contact portion, and a signal electrical contact portion corresponding to the signal terminal. The positive terminal is used to make electrical contact with the whole machine electrical contact portion, the negative terminal is used to make electrical contact with the negative electrical contact portion, and the signal terminal is used to make electrical contact with the corresponding signal electrical contact portion.

[0219] The distance between the positive and negative terminals can be greater than or equal to 1 mm. For example, the distance between the positive and negative terminals can be greater than or equal to 5 mm to reduce the risk of short circuit between the positive and negative terminals.

[0220] The distance between the positive and negative electrical contacts can be greater than or equal to 1 mm. For example, the distance between the positive and negative electrical contacts can be greater than or equal to 5 mm.

[0221] In some examples, the controller can be used to acquire the impedance between the positive and negative terminals and determine whether liquid has entered the fan mounting cavity 110 based on the impedance between the positive and negative terminals. The controller can also be used to issue a control command to instruct the fan module 200 to stop supplying power or reduce the voltage supplied to the fan module 200 when liquid is detected in the fan mounting cavity 110. For example, this control command can be used to increase the impedance threshold affecting the function.

[0222] In some examples, the surfaces of the electrical contact terminal 170 and the first electrical contact portion 224 have an anti-corrosion coating to improve the service life of the electrical contact terminal 170 and the first electrical contact portion 224.

[0223] In some examples, a protection circuit is provided between at least one of the positive and negative terminals and the power supply device. The protection circuit is used to limit current or voltage when there is an abnormal electrical connection at the positive and negative terminals, so as to avoid short circuit between the positive and negative terminals.

[0224] The positive and negative terminals can be electrically connected to the controller, which can be used to obtain the voltage or current at the positive and negative terminals. The controller can also issue a command to indicate an abnormal electrical connection when the voltage or current at the positive and negative terminals is not within a preset range, so as to remind the user to clean and maintain it.

[0225] In some possible implementations, when the fan module 200 is not in the inserted position, the electrical connection between the fan module 200 and the electrical connection device 5 is disconnected. At this time, the controller can determine whether the fan module 200 is in the inserted position by whether the fan module 200 is powered on. When the fan module 200 is not in the inserted position, the fan module 200 cannot operate.

[0226] In some possible implementations, when the fan module 200 is not in the extended position, the electrical connection between the fan module 200 and the electrical connector 5 is disconnected. At this time, the controller can determine whether the fan module 200 is in the extended position by whether the fan module 200 is powered on. When the fan module 200 is not in the extended position, the fan module 200 cannot operate.

[0227] Figure 24 This is a schematic diagram showing the fan module of another mobile terminal in the inserted position, as provided in an embodiment of this application. Figure 25 for Figure 24 The diagram provided shows the fan module of the mobile terminal in the extended position.

[0228] like Figure 24 , Figure 25 As shown, in some other possible embodiments, when the fan module 200 moves to any position between the insertion position and the extension position along the first direction, the fan module 200 is electrically connected to the power supply device through the electrical connection device 5.

[0229] In this way, the fan module 200 can be powered at any position between the inserted and extended positions, so that the fan module 200 can operate for heat dissipation at any position between the inserted and extended positions. In addition, it also facilitates the control of the fan module 200 when it moves between the inserted and extended positions.

[0230] In the example where the fan module 200 is electrically connected to the power supply device via the electrical connection device 5 when it moves to any position between the insertion position and the extension position along the first direction, the fan module 200 and the fan mounting cavity 110 can form a variable air duct, and the controller can control the fan module 200 in the extension position to operate or stop operating.

[0231] For example, when the fan module 200 is in the extended position: the controller can issue a control command to instruct the display screen 2 whether to control the fan module 200 to continue operating. After receiving a signal instructing the fan module 200 to operate, the controller controls the fan module 200 to continue operating; after receiving a signal instructing the fan module 200 to stop operating, the controller controls the fan module 200 to stop operating.

[0232] In some possible implementations, at least one of the second electrical contact 171 and the first electrical contact 224 is a strip-shaped structure extending along a first direction. When the fan module 200 is in the extended position, a portion of the fan module 200 is located within the fan mounting cavity 110, and a portion extends outward through the fan socket 50 to the outside of the housing assembly 1, with at least a portion of the first electrical contact 224 located within the fan mounting cavity 110. When the fan module 200 moves to any position along the first direction between the inserted position and the extended position, the first electrical contact 224 is in electrical contact with the second electrical contact 171.

[0233] This facilitates electrical connection between the fan module 200 and the power supply device when the fan module 200 is moved to any position between the insertion position and the extension position. Furthermore, the electrical connection device 5 has minimal impact on the movement of the fan module 200 within the fan mounting cavity 110.

[0234] For example, the second electrical contact 171 is a strip structure extending along the first direction, and when the fan module 200 is in the extended position, the first electrical contact 224 is located inside the fan mounting cavity 110.

[0235] In this way, the first electrical contact 224 is less likely to be damaged by moving to the outside of the housing assembly 1.

[0236] In some examples where the second electrical contact 171 is a strip structure extending along the first direction, and the first electrical contact 224 is located in the fan mounting cavity 110 when the fan module 200 is in the extended position, the inner wall of the fan socket 50 may be provided with a third sealing ring (not shown). The third sealing ring is pressed between the fan module 200 inserted into the fan socket 50 and the inner wall of the fan socket 50. The third sealing ring can be used to seal the connection between the fan module 200 inserted into the fan socket 50 and the inner wall of the fan socket 50.

[0237] This allows the fan module 200 to be sealed at the fan socket 50 at any position between the insertion position and the extension position, and prevents dust and liquid from entering the fan mounting cavity 110.

[0238] In some possible implementations, the electrical connection device 5 can be a flexible printed circuit board (FPC). The FPC can be connected to the insertion end of the fan module 200. When the fan module 200 is in the insertion position, the portion of the FPC located within the fan mounting cavity 110 can be bent and housed on the side facing the insertion end of the fan module 200. This facilitates electrical connection between the fan module 200 and the power supply device when the fan module 200 is moved to any position between the insertion and extension positions.

[0239] In some possible implementations, the fan assembly 220 includes a fan 221 for active air cooling of the mobile terminal. A cover plate 210 is fixedly disposed at one end of the fan 221 in a first direction. When the mobile terminal is in the fan-locked state, the fan 221 is locked and fixed to the first structural member 100. When the mobile terminal is in the fan-unlocked state, the fan 221 is released from the first structural member 100, and at least a portion of the fan 221 can extend to the outside of the housing assembly 1 through the fan connector 50, or at least a portion of the fan 221 can be inserted back into the fan mounting cavity 110 through the fan connector 50. At this time, the fan 221 is electrically connected to the electrical connection device 5. When the fan module 200 has a first electrical contact portion 224, the fan 221 also has a first electrical contact portion.

[0240] In this way, the structure of the fan module 200 is relatively simple, which makes it easier to install a larger fan 221, thereby increasing the air volume of the fan 221.

[0241] Figure 26 This is a schematic diagram of a fan module provided in an embodiment of this application.

[0242] like Figure 26 As shown, in some other possible embodiments, the fan assembly 220 may include a fan mount 222 and a fan 221, with the fan 221 used for active air cooling of the mobile terminal. A cover plate 210 is fixedly disposed at one end of the fan mount 222 in a first direction, and the fan 221 is fixedly disposed on the fan mount 222. The fan 221 is disposed on one side of the fan mount 222 in a second direction, and the fan mount 221 is used to support the fan 221. When the mobile terminal is in the fan-locked state, the fan mount 222 is locked and fixed to the first structural member 100. When the mobile terminal is in the fan-unlocked state, the fan mount 222 is released from the first structural member 100, and the fan mount 222 can drive the fan 221 to extend out to the outside of the housing assembly 1 through the fan connector 50, or the fan mount 222 can drive the fan 221 to insert back into the fan mounting cavity 110 through the fan connector 50.

[0243] This allows the fan 221 to extend fully out of the housing assembly 1 when the fan assembly 220 is partially located within the fan mounting cavity 110, facilitating maintenance of the fan 221. Furthermore, it allows for the installation of other components such as the heat dissipation structure 640 on the fan assembly 220, making the structure of the fan module 200 more flexible.

[0244] For example, the heat dissipation structure 640 may include one or more of the following: heat dissipation fins, heat pipes, heat spreaders, etc. The heat dissipation structure 640 can be used to improve the heat exchange efficiency during air cooling and enhance the heat dissipation capacity for heat-generating devices and the entire machine.

[0245] In some possible implementations, the fan 221 is non-detachably connected to the fan mount 222, and the fan 211 cannot be removed from the fan mount 222.

[0246] In some other possible implementations, the fan 221 is detachably connected to the fan mount 222.

[0247] This makes it easy to remove the fan 221 from the fan mount 222 for routine maintenance or repair.

[0248] For example, the fan 221 can be detachably connected to the fan mount 222 by means of snap-fit, fastener connection or other methods.

[0249] In some examples where the fan assembly 220 includes a fan mount 222 and a fan 221, the fan mount 222 is electrically connected to the electrical connection device 5, and the fan 221 is electrically connected to the fan mount 222, such that the fan 221 can be electrically connected to the electrical connection device 5 through the fan mount 222. When the fan module 200 has a first electrical contact 224, the fan mount 222 may have a first electrical contact 224, and the fan 221 is electrically connected to the first electrical contact 224.

[0250] For example, the fan mount 222 can make electrical contact with the fan 221 mounted on the fan mount 222 via terminals.

[0251] In some examples where the fan module 200 includes an anti-detachment structure 630, the anti-detachment structure 630 may be mounted on the fan mount 222.

[0252] The fan module 200 has a module air inlet and a module air outlet. Air enters the fan module 200 through the module air inlet and flows out of the fan module 200 through the module air outlet.

[0253] Figure 27 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0254] like Figure 27 As shown, in some possible embodiments, the fan mounting cavity 110 is connected to the first device mounting cavity 31. When the fan module 200 is in the insertion position, the module air inlet and the module air outlet are located inside the fan mounting cavity 110 and are connected to the fan mounting cavity 110.

[0255] In this way, the fan module 200 can drive the air circulation within the first device mounting cavity 31 and the fan mounting cavity 110, achieving a uniform temperature effect. Furthermore, there is no need to install ventilation openings on the outer surface of the mobile terminal, thus not affecting its appearance.

[0256] For example, the air outlet of the fan module 200 can be directed toward heat-generating devices such as the chip 6 to create a jet heat exchange effect, thereby reducing the temperature of heat-generating devices such as the chip 6.

[0257] In the example where the fan mounting cavity 110 is connected to the first device mounting cavity 31, when the fan module 200 is in the extended position and electrically connected to the power supply device, the fan module 200 can obtain fresh air from the outside of the housing assembly 1 to enter and exit the first device mounting cavity 31, thereby displacing the hot air in the first device mounting cavity 31 and improving the heat dissipation effect on the heat-generating device in the first device mounting cavity 31.

[0258] Figure 28 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0259] like Figure 28 As shown, in some other possible embodiments, the fan mounting cavity 110 is isolated from the first device mounting cavity 31, and the heat-generating device is connected to the first structural member 100 via a heat-conducting component 700. The fan module 200 has a module air inlet and a module air outlet. Both the module air inlet and the module air outlet are connected to the outside of the housing assembly 1.

[0260] At this time, the heating device can transfer heat to the first structural component 100, and the fan module 200 can draw fresh air from the outside of the housing assembly 1 to remove the heat from the first structural component 100.

[0261] In this way, the fan module 200 has good heat dissipation performance. In addition, when the fan module 200 is in the extended position, it will not damage the sealing performance of the first device mounting cavity 31, and the sealing performance of the first device mounting cavity 31 is good.

[0262] In the example where the fan mounting cavity 110 and the first device mounting cavity 31 are isolated from each other, the fan mounting cavity 110 and the first device mounting cavity 31 are located in two independent sealed waterproof and dustproof systems. The electrical connection parts of the motherboard 3, battery 4, chip 6, and display screen 2 are located in the sealed waterproof and dustproof system where the first device mounting cavity 31 is located, and are physically isolated from the fan mounting cavity 110. The heat generated by the motherboard 3, battery 4, chip 6, display screen 2 and other devices can be transferred to the first structural component 100 through the heat conduction component 700, and then dissipated to the external environment by the fan module 200 through forced convection, which can give the mobile terminal better heat dissipation performance.

[0263] The fan mounting cavity 110 and the first device mounting cavity 31 are located in two independent sealed waterproof and dustproof systems. During routine maintenance and repair of the fan module 200, or when the waterproofing of the fan mounting cavity 110 fails, the sealed waterproof and dustproof performance of the first device mounting cavity 31, where the motherboard 3, battery 4, chip 6, and electrical connection parts of the display screen 2 are located, is not affected. The components in the first device mounting cavity 31 can work normally and reliably, thus possessing strong system fault tolerance design capability and system waterproof and dustproof robustness for the fan module 200, facilitating routine maintenance and non-destructive repair of the fan module 200.

[0264] In some examples, the waterproof and dustproof rating of the fan mounting cavity 110 is lower than that of the first device mounting cavity 31. This makes the installation and ventilation of the fan module 200 easier.

[0265] For example, the waterproof and dustproof rating of the fan mounting cavity 110 can be IP57 or IP67, and the waterproof and dustproof rating of the first device mounting cavity 31 can be IP68 or higher.

[0266] When the housing assembly 1 includes the decorative element 20 and the first device mounting cavity 31 is connected to the second device mounting cavity 41, the waterproof and dustproof rating of the first device mounting cavity 31 refers to the waterproof and dustproof rating of the entire cavity formed by the connection of the first device mounting cavity 31 and the second device mounting cavity 41.

[0267] In some examples, the thermally conductive component 700 may include a thermal interface material 710, and heat-generating devices such as the chip 6 may be connected to the first structural component 100 through the thermal interface material 710.

[0268] Figure 29 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0269] like Figure 29 As shown, the motherboard 3 is provided with a first chip 6a and a second chip 6b. The heat conduction component 700 includes a heat conduction plate 720, a thermal interface material 710, and a shielding cover 730. The heat conduction plate 720 is connected to the first structural component 100 through the thermal interface material 710. The first chip 6a is connected to the heat conduction plate 720 through the thermal interface material 710. The shielding cover 730 is provided on the outer side of the second chip 6b. The second chip 6b is connected to the inner wall of the shielding cover 730 through the thermal interface material 710. The outer wall of the shielding cover 730 is connected to the heat conduction plate 720 through the thermal interface material 710.

[0270] For example, the heat-conducting plate 720 may include, but is not limited to, a heat spreader, a graphite plate, a middle frame, etc.

[0271] In some examples, the heat-conducting component 700 may include a heat-conducting plate 720, which may be integral with the first structural member 100. The heat-conducting plate 720 may be connected to the heat-generating device through a thermal interface material 710.

[0272] In some examples, the thermally conductive component 700 may include a shield 730, which may be integral with the first structural member 100. The shield 730 may be connected to the heat-generating device through a thermal interface material 710.

[0273] Figure 30 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0274] like Figure 30 As shown, in some possible embodiments, a heat dissipation structure 640 is fixedly connected to the first structural member 100. The heat dissipation structure 640 is located within the fan mounting cavity 110, and heat from the heat-generating device can be transferred to the heat dissipation structure 640 through the first structural member 100. The fan module 200 can remove the heat from the heat dissipation structure 640 by drawing fresh air from the outside of the housing assembly 1.

[0275] In this way, the thermal conductivity between the first structural component 100 and the heat dissipation structure 640 is relatively high, and the fan module 200 has a high efficiency in dissipating heat from the first structural component 100.

[0276] Figure 31 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0277] like Figure 31 As shown, in some examples where the fan assembly 220 of the fan module 200 includes a fan mount 222, the fan assembly 220 may include a heat dissipation structure 640. The heat dissipation structure 640 is fixedly connected to the fan mount 222, and the heat dissipation structure 640 exchanges heat with the first structural member 100 through the fan mount 222. That is, the heat on the heat-generating device can be transferred to the heat dissipation structure 640 through the first structural member 100 and the fan mount 222. In this way, when the fan module 200 is in the extended position, at least a portion of the heat dissipation structure 640 can be brought to the outside of the housing assembly 1, which is beneficial to the heat dissipation of the heat dissipation structure 640.

[0278] Figure 32 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0279] like Figure 32As shown, in some possible embodiments, the housing assembly 1 has a first vent 810 and a second vent 820. Both the first vent 810 and the second vent 820 communicate with the fan mounting cavity 110 and the outside of the housing assembly 1. When the fan module 200 is in the inserted position, both the module inlet and the module outlet are located within the fan mounting cavity 110. One of the module inlet and the module outlet communicates with the first vent 810 through the fan mounting cavity 110, and the other of the module inlet and the module outlet communicates with the second vent 820.

[0280] In this way, the air intake and exhaust of the fan module 200 are less restricted by the size of the fan module 200 itself, making it easier to achieve a larger air volume intake and exhaust of the fan module 200.

[0281] Taking the first vent 810 connected to the module's air outlet and the second vent 820 connected to the module's air inlet when the fan module 200 is in the insertion position as an example, air from the external environment can flow through the second vent 820 to the heat dissipation structure 640 via the fan 211 for heat exchange. After heat exchange, the air then flows out of the fan mounting cavity 110 through the first vent 810. Alternatively, air from the external environment can flow through the second vent 820 to the heat dissipation structure 640 for heat exchange, and then flow out of the fan mounting cavity 110 via the fan 211 and the first vent 810.

[0282] The connection between the first vent 810 and the second vent 820 and the module air inlet and outlet depends on the architecture design and is not limited in this application. For example, air can be introduced through the second vent 820 located on the left and right sides of the housing assembly 1, and after the airflow passes through the fan module 200 and the heat sink 640, it can be discharged through the first vent 810 on the upper side of the housing assembly 1.

[0283] In some examples, the second vent 820 may be integrally machined with the trim piece 20, such as being located on the side or front of the trim piece 20.

[0284] For example, a dustproof structure can be provided at the first vent 810 and the second vent 820 to prevent dust from easily entering the fan module 200 and the fan mounting cavity 110. In addition, it also facilitates dust removal from the dustproof structure. The waterproof and dustproof assembly may include the dustproof structure.

[0285] For example, a dustproof structure may include a dustproof net.

[0286] For example, when the first structural member 100 is fixedly connected to the side 11 and the second direction is the thickness direction of the mobile terminal, the side 11 may have a first vent 810 and the rear cover 12 may have a second vent 820. At this time, the fan 211 of the fan module 200 may be a mechanical centrifugal fan that draws air in along the thickness direction of the mobile terminal and discharges air in a direction perpendicular to the airflow direction. In high power consumption or high performance mode, the fan module 200 may extend outside the housing assembly 1 to significantly reduce the airflow resistance, thereby achieving high-performance airflow. The airflow through the heat dissipation structure 640 is large, and the heat dissipation performance is good.

[0287] Figure 33 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0288] like Figure 33 As shown, in some possible embodiments, the housing assembly 1 has a first vent 810 that connects the fan mounting cavity 110 to the outside of the housing assembly 1. When the fan module 200 is in the inserted position, one of the module air inlet and the module air outlet is located within the fan mounting cavity 110 and communicates with the first vent 810 through the fan mounting cavity 110, while the other of the module air inlet and the module air outlet is located at one end of the fan module 200 facing the outside of the housing assembly 1 in a first direction.

[0289] This allows for smoother airflow into and out of the fan mounting cavity 110, resulting in higher heat dissipation efficiency for the fan module 200. Furthermore, fewer openings on the housing assembly 1 minimize its impact on the appearance of the housing assembly 1. Additionally, reducing the number of openings on the first structural member 100 and the need for airflow channels formed by the first structural member 100 simplifies its structure.

[0290] Taking the first vent 810 and the module air outlet as an example when the fan module 200 is in the insertion position, the air in the external environment can flow through the module air inlet to the heat dissipation structure 640 for heat exchange through the fan 211, and the air after heat exchange can then flow out of the fan mounting cavity 110 through the first vent 810. Alternatively, the air in the external environment can flow through the module air inlet to the heat dissipation structure 640 for heat exchange, and then flow out of the fan mounting cavity 110 through the fan 211 and the first vent 810.

[0291] For example, a dustproof structure can be provided at the first vent 810 and the module air inlet and module air outlet located at the end of the fan module 200 facing the outer side of the housing assembly 1 in the first direction, so that dust is not easy to enter the fan module 200 and the fan mounting cavity 110. In addition, it is also convenient to remove dust from the dustproof structure.

[0292] In some possible implementations, the housing assembly 1 has a first vent 810 that connects the fan mounting cavity 110 to the outside of the housing assembly 1. When the fan module 200 is in the extended position, the module air inlet is located on the outside of the housing assembly 1, and the module air outlet is located inside the fan mounting cavity 110 and communicates with the first vent 810. When the fan module is in the inserted position, both the module air inlet and the module air outlet are located inside the fan mounting cavity. Thus, when the fan module 200 is in the extended position, air from the external environment can flow through the module air inlet through the fan mounting cavity 110 and return to the external environment through the first vent 810 for active air cooling.

[0293] Figure 34 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0294] like Figure 34 As shown, the orientation of the first vent 810 can be perpendicular to the second direction. For example, when the first structural member 100 is fixedly connected to the side 11 and the second direction is the thickness direction of the mobile terminal, the side 11 can have the first vent 810. This helps to reduce the thickness of the mobile terminal.

[0295] Figure 35 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0296] like Figure 35 As shown, the first vent 810 can face the second direction. For example, when the first structural member 100 is fixedly connected to the side 11 and the second direction is the thickness direction of the mobile terminal, the back cover 12 can have the first vent 810. This helps to reduce the length of the first structural member 100 and reduce the space occupied by the first structural member 100 within the housing assembly 1.

[0297] Figure 36 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0298] like Figure 36 As shown, in some examples where the first vent 810 is located on the rear cover 12, the projection of the first vent 810 along the second direction lies within the projection of the fan module 200 in the insertion position along the second direction. This facilitates a reduction in the length of the first structural member 100 and reduces the space occupied by the first structural member 100 within the housing assembly 1.

[0299] Figure 37 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0300] like Figure 37As shown, in some other examples where the first vent 810 is located on the rear cover 12, the projection of the first vent 810 along the second direction is outside the projection of the fan module 200 in the second direction when it is in the insertion position. This makes it easier for the fan module 200 to receive or expel air.

[0301] Figure 38 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0302] like Figure 38 As shown, in some possible embodiments, the cover plate 210 of the fan module 200 has a third vent 830 and a fourth vent 840, one of which is a module air inlet and the other is a module air outlet. The fan 221 of the fan module 200 has a fan air inlet and a fan air outlet.

[0303] In some examples, one of the fan inlet and fan outlet is connected to the outside of the housing assembly 1 via a third vent 830. When the fan module 200 is in the inserted position, the other of the fan inlet and fan outlet is located within the fan mounting cavity 110, and a fourth vent 840 connects the fan mounting cavity 110 to the outside of the housing assembly 1.

[0304] In this way, fresh air from the outside of the housing assembly 1 can displace the air inside the fan mounting cavity 110 through the third vent 830 and the fourth vent 840, thereby dissipating heat from the mobile terminal. Furthermore, vents are not required on the housing assembly 1, thus not affecting its appearance. Additionally, reducing the number of openings on the first structural member 100 and the need for air ducts formed by the first structural member 100 simplifies its structure and helps reduce the thickness of the mobile terminal.

[0305] Figure 39 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0306] like Figure 39 As shown, in some examples where the heat dissipation structure 640 is fixedly connected to the fan mount 222, the fan assembly 220 of the fan module 200 further includes a second structural member 225. The second structural member 225 is fixedly disposed on the fan mount 222 and is used to form a module air duct 226. A third vent 830 connects the outside of the housing assembly 1 with the module air duct 226. One of the fan inlet and the fan outlet is connected to the third vent 830 through the module air duct 226, and the other of the fan inlet and the fan outlet is connected to the outside of the housing assembly 1 through a fourth vent 840. The heat dissipation structure 640 is disposed within the module air duct 226.

[0307] In this way, fresh air from the outside of the housing assembly 1 can displace the air in the module air duct 226 through the third vent 830 and the fourth vent 840, thereby dissipating heat from the mobile terminal. Furthermore, vents are not required on the housing assembly 1, thus not affecting its appearance. Additionally, reducing the openings on the first structural member 100 and the need for air ducts formed by the first structural member 100 simplifies its structure and helps reduce the thickness of the mobile terminal. Moreover, when the fan module 200 is in the extended position, the operating fan 221 can continue to dissipate heat from the heat dissipation structure 640.

[0308] Figure 40 This is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0309] like Figure 40 As shown, in some examples, the fan assembly 220 includes multiple fans 221, and the cover plate 210 has multiple fourth vents 840 corresponding to each fan 221. One of the fan inlet and fan outlet of each fan 221 is connected to a third vent 830 through a module air duct 226, and the other of the fan inlet and fan outlet of each fan 221 is connected to the outside of the housing assembly 1 through the corresponding fourth vent 840. In this way, the fan module 200 can have a better heat dissipation effect.

[0310] In some possible implementations, the fan module 200 is a piezoelectric fan module. That is, the fan 221 of the fan module 200 is a piezoelectric fan. This allows for a thinner piezoelectric fan, facilitating a reduction in the thickness of the fan module 200, lowering the size requirements for the housing assembly 1 and the fan connector 50, and simplifying the installation of the fan module 200 on mobile terminals. Furthermore, the piezoelectric fan offers greater flexibility in its air intake and exhaust directions, allowing for more flexible arrangement of the fan module 200. Additionally, the piezoelectric fan has a larger pressure head, facilitating the installation of a dustproof structure 650 with a waterproof and breathable membrane at the air intake and exhaust ends.

[0311] In the example where the fan module 200 is a piezoelectric fan module, the module air inlet and the module air outlet of the fan module 200 are provided with a dustproof structure 650 with a waterproof and breathable membrane. This makes it difficult for dust to enter the fan module 200, which is conducive to the reliable operation of the piezoelectric fan, which is more sensitive to dust.

[0312] For example, the dustproof structure 650 with a waterproof and breathable membrane may include a waterproof and breathable membrane and a dustproof net. Both the dustproof net and the waterproof and breathable membrane are fixedly connected to the fan module 200, and the waterproof and breathable membrane is disposed inside the dustproof net. That is, at the air inlet of the module, air first flows through the dustproof net and then through the waterproof and breathable membrane into the fan module 200; at the air outlet of the module, air inside the fan module 200 first flows through the waterproof and breathable membrane and then through the dustproof net out of the fan module 200.

[0313] When the fan module 200 is a piezoelectric fan module, the waterproof and dustproof rating of the fan mounting cavity 110 can be IP67 or higher.

[0314] In some other possible implementations, the fan module 200 is a mechanical fan module. That is, the fan 221 of the fan module 200 is a mechanical fan, for example, it can be a centrifugal fan.

[0315] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components.
