Description

Mobile terminal

[0001] The present application claims priority to the Chinese patent application No. 202410666444.2, filed on May 24, 2024, and entitled "Mobile terminal", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] Embodiments of the present application relate to the technical field of electronic products, in particular to a mobile terminal. BACKGROUND

[0003] With the continuous improvement of the performance of mobile terminals such as mobile phones, tablet computers, smart watches, etc., thermal design has become a bottleneck for the performance of mobile terminals. At present, mobile terminals, taking mobile phones as an example, often use internal heat spreading through heat pipes, vapor chambers (VC), graphite sheets, graphene films, and thermal interface materials (TIM) for natural heat dissipation. Due to the strict limitations on the volume and thickness of mobile terminals, natural heat dissipation has been difficult to meet the power consumption requirements of applications such as AI, gaming, video calls, and satellite communication. The equivalent heat exchange coefficient of active air cooling heat dissipation through a fan module can reach 2-10 times that of natural heat dissipation, and active air cooling heat dissipation can improve the heat dissipation capacity by more than 50% compared to natural heat dissipation, which is an important way to improve the performance of mobile terminals.

[0004] In related technologies, the fan module is often arranged in the shell assembly of the mobile terminal. The mobile terminal is prone to problems such as falling, extrusion, or collision during use or carrying. When falling, extrusion, or collision occurs, the fan module is prone to a large local impact force, the risk is much higher than that of the fan module in a static application scenario, the fan module is relatively more prone to local deformation, and the performance of the fan module is prone to be affected. In addition, under long-term use, dust, fiber dirt, and the like in the environment will accumulate on the surface of the blades of the fan module and in the air duct, which will cause the air volume and heat dissipation capacity of the fan module to continuously decay, and cause problems such as noise and abnormal sound. At present, it is difficult for users to maintain the fan module. The reliability of the fan module as a moving part will restrict the performance of the mobile terminal. If the heat dissipation, noise, or vibration performance of the fan module deteriorates significantly, the mobile terminal needs to be disassembled (such as disassembling the back cover or the display screen, etc.) for maintenance of the fan module. Some mobile terminals have high requirements for waterproof and dustproof levels, and disassembly may damage the waterproof and dustproof and sealing requirements of the mobile terminal, which is prone to cause the mobile terminal as a whole to be scrapped, and the operability of disassembly for maintenance of the fan module is poor. In addition, during the process of disassembly for maintenance of the fan module, other components or devices such as the shell assembly, side keys, display screens, and batteries may be scratched, which is prone to cause other components or devices to be scrapped.

[0005] Therefore, in the related art mobile terminal, it is difficult to maintain and repair the fan module, which results in low reliability of the fan module and the mobile terminal using the fan module, and the mobile terminal cannot be widely used in the future, which restricts the performance of the mobile terminal such as a mobile phone. SUMMARY

[0006] Embodiments of the present application provide a mobile terminal, which can be more convenient to maintain and repair the fan module.

[0007] Embodiments of the present application provide a mobile terminal, which includes a housing assembly, a fan module and a first structure. The first structure is fixedly arranged on an inner wall of the housing assembly, and the first structure and the housing assembly form a fan mounting cavity. The housing assembly has a fan insertion opening which is in communication with the fan mounting cavity and an outside of the housing assembly, and the fan module is inserted into the fan mounting cavity through the fan insertion opening. The mobile terminal has a fan locking state and a fan unlocking state. When the mobile terminal is in the fan locking state, the fan module is locked and fixed with the first structure. When the mobile terminal is in the fan unlocking state, the fan module is released from the first structure, and the fan module can move along a first direction between an insertion position and an extension position, so that at least part of the fan module can be extended to the outside of the housing assembly through the fan insertion opening, or at least part of the fan module can be inserted back into the fan mounting cavity through the fan insertion opening. The first direction is the insertion and extraction direction of the fan module.

[0008] The mobile terminal provided by the embodiments of the present application can make at least part of the fan module extend to the outside of the shell assembly through the fan insertion port when routine maintenance or repair of the fan module is needed, so as to facilitate routine maintenance such as dust removal and cleaning of the fan module, or repair work such as replacement. After the maintenance or repair of the fan module is completed, the fan module can be inserted back into the fan mounting cavity through the fan insertion port. The fan module does not need to be disassembled from the display screen, the side and the rear cover, and the sealing between the display screen, the side and the rear cover is not damaged. After the repair of the fan module is completed, the display screen, the side and the rear cover do not need to be resealed. In summary, the maintenance and repair of the fan module are of low cost and low difficulty, and the mobile terminal as a whole is not easily scrapped. In addition, when the fan module extending to the outside of the shell assembly is repaired, the repair tool does not need to extend into the shell assembly, and other components or devices of the mobile terminal are not easily damaged or scrapped, and the repair cost is small. The mobile terminal provided by the embodiments of the present application is convenient for maintenance and repair of the fan module. In addition, the fan mounting cavity is formed by the first structure for inserting the fan module, which facilitates locking and fixing of the fan module and the shell assembly, and stable connection. When the mobile terminal is in the fan locking state, the fan module and the shell assembly are locked and fixed more stably, which is beneficial to maintaining the performance of the fan module. When the mobile terminal is in the fan unlocking state, the fan module can move in the first direction, which is easy to operate, and the process of extending and inserting the fan module does not easily damage the whole machine.

[0009] In some possible embodiments, the mobile terminal further includes power supply devices and electrical connection devices. The shell assembly further has a device mounting cavity outside the fan mounting cavity, the power supply devices are arranged in the device mounting cavity, and part of the electrical connection devices is arranged in the device mounting cavity and part of the electrical connection devices is arranged in the fan mounting cavity. When the fan module is in the inserted position, the fan module is electrically connected to the power supply devices through the electrical connection devices. In this way, the power supply devices arranged in the device mounting cavity can supply power to the fan module in the inserted position to drive the fan module when the fan module is in the inserted position. When the fan module operates in the inserted position, the overall anti-falling performance of the mobile terminal is good, and the appearance of the mobile terminal does not change.

[0010] In some possible implementation manners, the mobile terminal further comprises power supply devices and electrical connection devices. The housing assembly further has a device mounting cavity outside the fan mounting cavity, and the power supply devices are arranged in the device mounting cavity, and part of the electrical connection devices is arranged in the device mounting cavity and part of the electrical connection devices is arranged in the fan mounting cavity. When the fan module is in the extended position, the fan module is electrically connected to the power supply devices through the electrical connection devices. In this way, the power supply devices arranged in the device mounting cavity can supply power to the fan module in the extended position to drive the fan module when the fan module is in the extended position. When the fan module operates in the extended position, the air inlet of the fan module in the inserted position is exposed to the atmosphere, which greatly increases the air inlet area of the fan module and reduces the air inlet flow resistance, thereby significantly improving the performance of the fan module and supporting high-load high-power applications. After the fan module is inserted into the housing assembly, the mobile terminal has better overall drop resistance.

[0011] For heavy-load high-performance demand services, the fan module extends out of the housing assembly to operate. When the fan module operates in the extended position, the air inlet of the fan module in the inserted position is exposed to the atmosphere, which greatly increases the air inlet area of the fan module and reduces the air inlet flow resistance, thereby significantly improving the performance of the fan module and supporting high-load high-power applications. After the fan module is inserted into the housing assembly, the mobile terminal has better overall drop resistance.

[0012] In some possible implementation manners, when the fan module moves to any position between the inserted position and the extended position along the first direction, the fan module is electrically connected to the power supply devices through the electrical connection devices. In this way, the fan module in any position between the inserted position and the extended position can be powered to operate to dissipate heat. In addition, it is also convenient to control the fan module when the fan module moves between the inserted position and the extended position.

[0013] In some possible implementation manners, the electrical connection devices comprise electrical contact terminals fixedly arranged on the first structural member, and the fan module has first electrical contact parts. The electrical contact terminals comprise second electrical contact parts arranged in the fan mounting cavity and connecting parts arranged in the device mounting cavity and electrically connected to the power supply devices. The first electrical contact parts are used to electrically contact the second electrical contact parts, so that the fan module is electrically connected to the power supply devices through the electrical contact terminals. In this way, it is convenient to realize the electrical connection between the fan module and the power supply devices. In addition, the electrical connection devices have little effect on the movement of the fan module.

[0014] In some possible embodiments, at least one of the second electrical contact and the first electrical contact is a strip-shaped structure extending along the first direction. When the fan module is in the extended position, part of the fan module is located in the fan mounting cavity and part of the fan module extends outside the housing assembly through the fan insertion opening, and at least part of the first electrical contact is located in the fan mounting cavity. When the fan module moves to any position between the inserted position and the extended position along the first direction, the first electrical contact is in electrical contact with the second electrical contact. In this way, the electrical connection between the fan module in any position between the inserted position and the extended position and the power supply device is facilitated. In addition, the electrical connection device has less impact on the movement of the fan module.

[0015] In some possible embodiments, the fan module includes a cover plate and a fan assembly. The cover plate is fixedly arranged at one end of the fan assembly in the first direction, the fan assembly is inserted into the fan mounting cavity through the fan insertion opening, and the cover plate is located outside the housing assembly. When the fan module is in the inserted position, the cover plate covers the outer surface of the housing assembly, and the orthographic projection of the cover plate on the outer surface of the housing assembly covers the edge of the housing assembly at the fan insertion opening. When the fan module moves between the inserted position and the extended position along the first direction, at least part of the fan assembly extends outside the housing assembly through the fan insertion opening, or at least part of the fan assembly is inserted back into the fan mounting cavity through the fan insertion opening. In this way, the cover plate can limit the depth of the fan module inserted into the fan mounting cavity.

[0016] In some possible embodiments, the mobile terminal further includes a sealing ring arranged between the cover plate and the outer surface of the housing assembly, and the sealing ring surrounds the fan insertion opening along the circumferential direction of the fan insertion opening. When the fan module is in the inserted position, the sealing ring is compressed by the cover plate and the outer surface of the housing assembly, and the sealing ring seals the connection between the fan module and the housing assembly at the fan insertion opening. In this way, when the fan module is in the inserted position, the sealing performance of the mobile terminal is improved, and the overall reliability of the system is improved.

[0017] In some possible implementation manners, the fan assembly comprises a fan seat and a fan. A cover plate is fixedly arranged at one end of the fan seat in a first direction, and the fan is fixedly arranged on the fan seat and arranged at one side of the fan seat in a second direction. When the mobile terminal is in the fan locking state, the fan seat is locked and fixed with the first structural member. When the mobile terminal is in the fan unlocking state, the fan seat is released from the first structural member, and the fan seat can drive the fan to extend to the outside of the housing assembly through the fan socket or the fan seat can drive the fan to be inserted into the fan mounting cavity through the fan socket. The second direction is perpendicular to the first direction. In this way, the fan can be completely extended to the outside of the housing assembly when the fan assembly is partially located in the fan mounting cavity, and the fan is convenient to maintain or repair. In addition, the heat dissipation structure or the like can be arranged on the fan assembly, so that the structure of the fan module is more flexible.

[0018] In some possible implementation manners, the fan is detachably connected with the fan seat. In this way, the fan can be removed from the fan seat for maintenance or repair, so that the fan is more convenient to maintain or repair.

[0019] In some possible implementation manners, the mobile terminal further comprises a heat generating device arranged in the 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 the module air outlet are located in the fan mounting cavity and communicate with the fan mounting cavity. In this way, the fan module can drive the air in the device mounting cavity and the fan mounting cavity to flow, and the uniform temperature effect can be achieved. The ventilation opening does not need to be arranged on the outer surface of the mobile terminal, and the appearance of the mobile terminal is not affected.

[0020] In some possible implementation manners, the mobile terminal further comprises a heat generating device arranged in the device mounting cavity of the housing assembly. The fan mounting cavity and the device mounting cavity are isolated from each other, and the heat generating device is connected with the first structural member through a heat conduction assembly. The fan module has a module air inlet and a module air outlet. The module air inlet and the module air outlet both communicate with the outside of the housing assembly. In this way, the heat dissipation performance of the fan module is better. In addition, when the fan module is in the extended position, the sealing performance of the device mounting cavity is not damaged, and the sealing performance of the device mounting cavity is better.

[0021] When the fan mounting cavity and the device mounting cavity are isolated from each other, the fan mounting cavity and the device mounting cavity are located in two sets of independent sealing, waterproof and dustproof systems. The main board, the battery, the chip and the electric connection part of the display screen are arranged in the sealing, waterproof and dustproof system of the device mounting cavity and are physically isolated from the fan mounting cavity. The opening communicating with the fan mounting cavity does not affect the dustproof and waterproof performance of the device mounting cavity. The heat generated by the main board, the battery, the chip and the display screen can be transmitted to the first structural member through the heat conduction assembly and dissipated to the external environment through the forced convection of the fan module, so that the mobile terminal has better heat dissipation performance.

[0022] The fan mounting cavity and the device mounting cavity are located in two sets of mutually independent sealing, waterproof and dustproof systems. When the fan module is maintained or repaired daily, or the waterproof function of the fan mounting cavity fails, the sealing, waterproof and dustproof performance of the device mounting cavity where the electrical connection parts of the main board, the battery, the chip and the display screen are located is not affected, and the devices in the device mounting cavity can work normally and reliably, thereby having strong system fault tolerance design capability and system waterproof and dustproof robustness for the fan module, and facilitating the daily maintenance and non-destructive repair of the fan module.

[0023] In some possible embodiments, the waterproof and dustproof level of the fan mounting cavity is lower than that of the device mounting cavity. In this way, the fan module is easier to set and ventilate.

[0024] In some possible embodiments, the first structural member is fixedly connected with a heat dissipation structure, and the heat dissipation structure is located in the fan mounting cavity. In this way, the heat conduction efficiency between the first structural member and the heat dissipation structure is higher, and the efficiency of the fan module in dissipating heat from the first structural member is higher.

[0025] In some possible embodiments, the fan assembly of the fan module includes a heat dissipation structure, the heat dissipation structure is fixedly connected to the fan seat of the fan assembly, and the heat dissipation structure exchanges heat with the first structural member through the fan seat. In this way, when the fan module is in the extended position, at least part of the heat dissipation structure can be brought to the outside of the housing assembly, which is beneficial to the heat performance of the heat dissipation structure.

[0026] In some possible embodiments, the housing assembly has a first ventilation opening and a second ventilation opening, and the first ventilation opening and the second ventilation opening both communicate the fan mounting cavity and the outside of the housing assembly. When the fan module is in the inserted position, the module air inlet and the module air outlet are both located in the fan mounting cavity, one of the module air inlet and the module air outlet communicates with the first ventilation opening through the fan mounting cavity, and the other of the module air inlet and the module air outlet communicates with the second ventilation opening. In this way, the air inlet and air outlet of the fan module are less limited by the size of the fan module itself, and it is convenient to realize the air inlet and air outlet of the fan module with large air volume. The communication between the first ventilation opening and the second ventilation opening and the module air inlet and the module air outlet depends on the architectural design, which is not limited in the present application.

[0027] In some possible implementation manners, the shell assembly has a first venting opening which is in communication with the fan mounting cavity and the outside of the shell assembly. When the fan module is in the inserted position, one of the module air inlet and the module air outlet is located in the fan mounting cavity and is in communication with the first venting opening through the fan mounting cavity, and the other one of the module air inlet and the module air outlet is located at one end of the fan module which is directed towards the outside of the shell assembly along the first direction. In this way, air can flow in and out of the fan mounting cavity more smoothly, and the heat dissipation efficiency of the fan module is higher. In addition, there are fewer openings on the shell assembly, and the appearance of the shell assembly is less affected. Furthermore, the openings on the first structural member and the air duct formed by the first structural member can be reduced, and the structure of the first structural member can be simpler.

[0028] In some possible implementation manners, the cover plate of the fan module has a third venting opening and a fourth venting opening, one of the third venting opening and the fourth venting opening is the module air inlet, and the other one of the third venting opening and the fourth venting opening is the module air outlet. 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 is in communication with the outside of the shell assembly through the third venting opening. When the fan module is in the inserted position, the other one of the fan air inlet and the fan air outlet is located in the fan mounting cavity, and the fourth venting opening is in communication with the fan mounting cavity and the outside of the shell assembly. In this way, fresh air on the outside of the shell assembly can replace the air in the fan mounting cavity through the third venting opening and the fourth venting opening, and the mobile terminal can be cooled. In addition, the shell assembly can not need to be provided with a venting opening, and the appearance of the shell assembly is not affected. Furthermore, the openings on the first structural member and the air duct formed by the first structural member can be reduced, and the structure of the first structural member can be simpler, which is conducive to reducing the thickness of the mobile terminal.

[0029] In some possible implementation manners, the cover plate of the fan module has a third vent and a fourth vent, one of the third vent and the fourth vent is the module air inlet, and the other of the third vent and the fourth vent is the module air outlet. The fan assembly of the fan module further includes a second structural member fixedly arranged on the fan seat, and the second structural member is configured to form a module air duct, and the third vent is in communication with the outside of the shell assembly and the module air duct. The fan has a fan air inlet and a fan air outlet, one of the fan air inlet and the fan air outlet is in communication with the third vent through the module air duct, and the other of the fan air inlet and the fan air outlet is in communication with the outside of the shell assembly through the fourth vent, and the heat dissipation structure is arranged in the module air duct. In this way, the fresh air outside the shell assembly can replace the air in the module air duct through the third vent and the fourth vent, thereby dissipating heat for the mobile terminal. In addition, the shell assembly can not need to be provided with a vent, and the appearance of the shell assembly is not affected. In addition, the opening on the first structural member and the air duct formed by the first structural member can be reduced, the structure of the first structural member is relatively simple, and the thickness of the mobile terminal can be reduced. Furthermore, when the fan module is in the extended position, the running fan can continuously dissipate heat.

[0030] In some possible implementation manners, the fan module is a piezoelectric fan module, the air volume is small, and the pressure head is high. The module air inlet and the module air outlet of the fan module are provided with a dustproof structure having a waterproof and breathable film. In this way, the thickness of the fan module can be relatively small, and the fan module is convenient to arrange on the mobile terminal. In addition, the air inlet and air outlet directions of the piezoelectric fan are relatively flexible, and the arrangement of the fan module is relatively flexible. In addition, the dustproof structure having the waterproof and breathable film is beneficial to the long-term and reliable operation of the piezoelectric fan which is sensitive to dust.

[0031] In some possible implementation manners, the shell assembly includes a shell and a decoration piece. The decoration piece is fixedly connected with the shell, and the decoration piece protrudes from the outer surface of the shell. The first structural member is arranged in the decoration piece, the first structural member is fixedly arranged on the inner wall of the decoration piece, the first structural member and the decoration piece form a fan mounting cavity, and the decoration piece has a fan insertion port. In this way, the fan module can not occupy the space in the shell, and the arrangement of devices in the shell is facilitated, and the fan module is particularly suitable for ultra-thin mobile phones such as folding mobile phones.

[0032] In some possible implementation manners, the first structural member is provided with a locking mechanism. When the mobile terminal is in a fan locking state, the locking mechanism locks and fixes the fan module and the first structural member. When the mobile terminal is in a fan unlocking state, the locking mechanism releases the fixing of the fan module and the first structural member. In this way, the locking mechanism is relatively easy to arrange. In addition, when the fan module is extended to the outside of the shell assembly, the locking mechanism is not easy to be damaged due to being exposed.

[0033] In some possible implementation manners, the fan module is provided with a anti-disengagement structure fixedly arranged on the fan module, the anti-disengagement structure is located in the fan mounting cavity, and the anti-disengagement structure is used for abutting against the inner wall of the shell assembly when the fan module is in the extended position, so as to limit the fan module inserted in the fan mounting cavity from being disengaged from the shell assembly through the fan insertion opening. In this way, the fan module is kept in a state of being partially extended from the shell assembly and connected to the shell assembly, and the fan module partially extended from the shell assembly is facilitated to cool the mobile terminal.

[0034] In some possible implementation manners, the shell assembly is further provided with a pushing mechanism. At least part of the pushing mechanism is located in the fan mounting cavity. The pushing mechanism is used for pushing part of the fan module in the inserted position to the outside of the shell assembly through the fan insertion opening. In this way, the fan module is facilitated to be extended from the fan mounting cavity.

[0035] The mobile terminal provided by the embodiments of the present application can greatly improve the reliability and service life of the fan module, which is a bottleneck of the reliability of the whole machine, through daily maintenance and simple repair of the fan module, support high performance and high system reliability of the whole machine, release the restriction of the service life and reliability of the fan on the mobile terminal, and realize active heat dissipation of the mobile terminal which is much higher than natural heat dissipation.

DETAILED DESCRIPTION

[0077] The terms used in the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application, and the embodiments of the present application will be described in detail below in conjunction with the drawings.

[0078] Embodiments of the present application provide a mobile terminal, which can include but is not limited to a mobile phone, a tablet computer, an ultra-mobile personal computer (UMPC), a handheld computer, a walkie talkie, a netbook, a point of sales (POS) machine, a personal digital assistant (PDA), a wearable device, a virtual reality device, etc. Embodiments of the present application take the mobile terminal as a mobile phone for example to illustrate.

[0079] FIG. 1 is a schematic diagram of a mobile terminal according to an embodiment of the present application.

[0080] As shown in FIG. 1, in the embodiments of the present application, the mobile terminal can include a housing assembly 1 and a display screen 2, the display screen 2 is arranged on the housing assembly 1, and the housing assembly 1 has a cavity for arranging devices.

[0081] The housing assembly 1 includes a housing 10, the display screen 2 is arranged on one side of the housing 10 in the thickness direction, and the housing 10 can have a first cavity 30, the display screen 2 can be used to cover an opening of the first cavity 30 on one side of the housing 10 in the thickness direction, and the first cavity 30 can be used to arrange devices such as a mainboard 3 (as shown in FIG. 4), a battery 4 (as shown in FIG. 4), a chip 6 (as shown in FIG. 27), etc.

[0082] The housing 10 can include a middle frame (not shown), a side edge 11 and a back cover 12, the side edge 11 is fixedly arranged on the edge of the middle frame, the display screen 2 is arranged on one side of the side edge 11 in the thickness direction of the middle frame, the back cover 12 is connected to the other side of the side edge 11 in the thickness direction of the middle frame, and the side edge 11 and the back cover 12 are used to form the first cavity 30 (as shown in FIG. 4).

[0083] In some examples, the middle frame and the side edge 11 are an integral structure.

[0084] In other examples, the middle frame and the side edge 11 are a split structure, and the side edge 11 and the middle frame can be connected through nano injection molding.

[0085] For example, the display screen 2 can be bonded on the side edge 11.

[0086] For example, the back cover 12 can be arranged on the side edge 11 through at least one of bonding, fastener connection, clamping, etc.

[0087] In some examples, the mobile terminal can be a non-foldable device, for example, the mobile terminal can be a straight mobile phone. At this time, the housing assembly 1 includes one housing 10.

[0088] FIG. 2 is a schematic diagram of another mobile terminal according to an embodiment of the present application.

[0089] As shown in FIG. 2, in some examples, the mobile terminal can be a foldable device, for example, the mobile terminal can be a foldable phone. The shell assembly 1 can include a plurality of shells 10, and a rotation shaft mechanism (not shown) is arranged between two adjacent shells 10, and the two adjacent shells 10 are rotationally connected through the rotation shaft mechanism therebetween. Specifically, the middle frames 11 of the two adjacent shells 10 can be rotationally connected through the rotation shaft mechanism therebetween. When the mobile terminal is a foldable device, the display screen 2 can be a flexible screen, and the flexible screen can be attached to the plurality of shells 10. When the foldable device is in an unfolded state, the flexible screen can be located on the same side in the thickness direction of the plurality of shells 10 that are attached.

[0090] When the mobile terminal is a foldable device, each shell 10 can have a first cavity 30 therein. The main board 3 and the battery 4 can be arranged in the first cavities 30 of two different shells 10, respectively.

[0091] FIG. 3 is a schematic view of another mobile terminal provided by an embodiment of the present application.

[0092] As shown in FIG. 3, in some examples, the shell assembly 1 further includes a decorative piece 20, and the decorative piece 20 is fixedly connected to the side of the shell 10 away from the display screen 2. Specifically, the decorative piece 20 can be fixedly connected to the back cover 12. The decorative piece 20 protrudes from the outer surface of the shell 10 in which the decorative piece 20 is located, and the decorative piece 20 has a second cavity 40 (as shown in FIG. 6) therein. The second cavity 40 can be used to arrange a camera, a display device (such as a time display device, an ultraviolet radiation display device), etc. The second cavity 40 in the decorative piece 20 can be in communication with the first cavity 30 in the shell 10 in which the decorative piece 20 is located.

[0093] When the shell assembly 1 includes a plurality of shells 10, the decorative piece 20 can be fixedly connected to one of the shells 10.

[0094] To improve the heat dissipation performance of the mobile terminal, the mobile terminal further includes a fan module 200 (as shown in FIG. 4) for active air cooling heat dissipation, and the fan module 200 can be arranged in the shell assembly.

[0095] After the mobile terminal is used for a period of time, the fan module 200 is prone to problems such as dust accumulation and damage. When the fan module 200 has problems such as dust accumulation and damage, routine maintenance (such as dust removal) or repair of the fan module 200 is required.

[0096] In the related art, the fan module is arranged in the first chamber of the shell. When the fan module is maintained, the display screen or the back cover needs to be first disassembled from the side to expose the fan module, and then the fan module can be maintained. However, after the display screen or the back cover is disassembled from the side, the seal between the side and the display screen or the back cover is easily damaged. After the fan module is maintained, the side and the display screen or the back cover need to be resealed. The cost of maintaining the fan module is high, the operation is difficult, and the mobile terminal is easily scrapped as a whole. In addition, when the display screen or the back cover is disassembled to maintain the fan module in the first chamber, the shell assembly, the side key, the display screen, the battery and other components or devices of the mobile terminal are also easily damaged, causing the components or devices to be scrapped. The cost of the fan module is much lower than that of the display screen, the chip and the battery. The display screen, the chip and the battery are scrapped at a high maintenance cost. The mobile terminal in the related art is inconvenient to maintain the fan module and is difficult to maintain daily.

[0097] FIG. 4 is a schematic view of a fan module of a mobile terminal in an inserted position according to an embodiment of the present application, and FIG. 5 is a schematic view of the fan module of the mobile terminal in an extended position according to the embodiment of the present application. In the figures, the x direction is a first direction, and the first direction is the insertion and extraction direction of the fan module 200.

[0098] As shown in FIG. 4, based on this, in the embodiment of the present application, the mobile terminal further includes a first structure 100 fixedly arranged on the inner wall of the shell assembly 1. The first structure 100 and the shell assembly 1 form a fan mounting cavity 110. The shell assembly 1 has a fan socket 50 communicating the fan mounting cavity 110 with the outside of the shell assembly 1, and the fan module 200 is inserted into the fan mounting cavity 110 through the fan socket 50.

[0099] The mobile terminal has a fan locking state and a fan unlocking state. When the mobile terminal is in the fan locking state, the fan module 200 is locked and fixed with the first structure 100. When the mobile terminal is in the fan unlocking state, the fan module 200 is released from the first structure 100, and the fan module 200 can move between the inserted position and the extended position along the first direction, so that at least part of the fan module 200 can be extended to the outside of the shell assembly 1 through the fan socket 50 or at least part of the fan module 200 can be inserted back into the fan mounting cavity 110 through the fan socket 50. Specifically, when the fan module 200 moves from the inserted position to the extended position, at least part of the fan module 200 is extended to the outside of the shell assembly 1 through the fan socket 50. When the fan module 200 moves from the extended position to the inserted position, at least part of the fan module 200 is inserted back into the fan mounting cavity 110 through the fan socket 50.

[0100] In this way, when maintenance or repair of the fan module 200 is needed, at least part of the fan module 200 can be extended outside the shell assembly 1 through the fan insertion opening 50, so as to facilitate dust removal, cleaning and other maintenance of the fan module 200, or repair, replacement and other maintenance work of the fan module 200. After the maintenance or repair of the fan module 200 is completed, the fan module 200 can be inserted back into the fan mounting cavity 110 through the fan insertion opening 50. The display screen 2, the side edge 11 and the rear cover 12 do not need to be disassembled for the maintenance of the fan module 200, and the sealing between the display screen 2, the side edge 11 and the rear cover 12 is not easily damaged. After the maintenance or repair of the fan module 200 is completed, the display screen 2, the side edge 11 and the rear cover 12 do not need to be resealed, and the maintenance or repair cost of the fan module 200 is relatively low and the operation difficulty is relatively small, and the mobile terminal as a whole is not easily scrapped. In addition, when the fan module 200 extended outside the shell assembly 1 is repaired, the repair tool does not need to be inserted into the shell assembly 1, and other components or devices of the mobile terminal are not easily damaged, and the repair cost is relatively small. The mobile terminal provided by the embodiment of the present application is relatively convenient for maintenance or repair of the fan module 200. In addition, the fan mounting cavity 110 is formed by the first structure 100 for insertion of the fan module 200, which facilitates locking and fixing and stable connection of the fan module 200 and the shell assembly 1. When the mobile terminal is in the fan locking state, the fan module 200 and the shell assembly 1 are relatively stably locked and fixed, which is beneficial to maintaining the performance of the fan module 200. When the mobile terminal is in the fan unlocking state, the fan module 200 moves in the first direction relatively stably and is easy to operate. The process of extension and insertion of the fan module 200 does not easily damage the whole machine.

[0101] The first direction can be a length direction, or a width direction, or a thickness direction of the mobile terminal.

[0102] When the mobile terminal is a foldable device, the length direction of the mobile terminal is a length direction when the mobile terminal is in an unfolded state, the width direction of the mobile terminal is a width direction when the mobile terminal is in the unfolded state, and the thickness direction of the mobile terminal is a thickness direction when the mobile terminal is in the unfolded state.

[0103] When the mobile terminal is in the fan unlocking state, the fan module 200 can be in sliding cooperation with the cavity wall of the fan mounting cavity 110.

[0104] In some examples, when the fan module 200 is in the insertion position, the fan module 200 can be entirely accommodated in the fan mounting cavity 110.

[0105] In other examples, when the fan module 200 is in the insertion position, the fan module 200 is partially accommodated in the fan mounting cavity 110 and partially extended outside the shell assembly 1 through the fan insertion opening 50. In this way, the fan module 200 in the insertion position can be easily pulled out through the fan insertion opening 50.

[0106] The extended position can be determined according to actual needs. For example, when the fan module 200 is in the extended position, the fan module 200 can be extended to one third, or one half, or two thirds, or three thirds, or four thirds, or five fourths, or the entire outside of the shell assembly 1 in the first direction.

[0107] The first chamber 30 includes a first device mounting cavity 31, and the main board 3, the battery 4, the chip 6, and the like of the mobile terminal are disposed in the first device mounting cavity 31. The battery 4 can be electrically connected to the main board 3, the chip 6 can be disposed on and electrically connected to the main board 3, and the display screen 2 can be used to cover an opening of the first device mounting cavity 31 on one side of the shell 10 in the thickness direction.

[0108] For example, one or more chips 6 can be disposed on the main board 3.

[0109] For example, a system on a chip (SOC) chip, a power management unit (PMU) chip, and the like can be disposed on the main board 3.

[0110] We can refer to a device that generates more heat during work as a heat-generating device. The mobile terminal includes a heat-generating device, which can include but is not limited to the main board, the battery, the chip, the camera, and the like.

[0111] In some examples, the first structural member 100 is disposed in the shell 10, specifically, the first structural member 100 is located in the first chamber 30, the first structural member 100 is fixedly disposed on an inner wall of the shell 10, the first structural member 100 and the shell 10 surround to form the fan mounting cavity 110, and the shell 10 has the fan insertion port 50. At this time, the first chamber 30 includes the fan mounting cavity 110 and the first device mounting cavity 31, and the first device mounting cavity 31 is located outside the fan mounting cavity 110.

[0112] In this way, the distance between the fan module 200 and the heat-generating device disposed in the first device mounting cavity 31 is close, and the heat dissipation effect of the fan module 200 is good.

[0113] When the first structural member 100 is fixedly disposed on the inner wall of the shell 10, the first structural member 100 can be fixedly connected with at least one of the side edge 11 and the rear cover 12.

[0114] FIG. 6 is a schematic diagram of another mobile terminal provided by an embodiment of the present application.

[0115] As shown in FIG. 6, in the example in which the shell assembly 1 includes the decoration 20, the second cavity 40 can include a second device mounting cavity 41 in which a camera or the like device can be disposed, and the second device mounting cavity 41 can be in communication with the first device mounting cavity 31, and the camera or the like device disposed in the second device mounting cavity 41 can be electrically connected with the main board 3.

[0116] In some examples in which the shell assembly 1 includes the decoration 20, the first structure 100 can be disposed in the decoration 20, and in particular, the first structure 100 is located in the second cavity 40, and the first structure 100 is fixedly disposed on an inner wall of the decoration 20, and the first structure 100 and the decoration 20 together define a fan mounting cavity 110, and the decoration 20 has the fan insertion port 50.

[0117] In this way, the fan module 200 can not occupy space in the shell 10, and this facilitates the arrangement of devices in the shell 10. In addition, the fan module 200 requires sufficient thickness space and air inlet space for high performance, and this directly conflicts with the thin and light design of the mobile terminal, especially the appearance requirements of foldable devices. By disposing the first structure 100 and the fan module 200 in the decoration 20, the contradiction between the ultra-thin appearance and the high performance application of the fan module 200 can be solved.

[0118] In some examples in which the shell assembly 1 includes the decoration 20, the second cavity 40 includes the fan mounting cavity 110 and the second device mounting cavity 41, and the second device mounting cavity 41 is located outside the fan mounting cavity 110.

[0119] In other examples in which the shell assembly 1 includes the decoration 20, the decoration 20 can also be a decoration 20 that is solely used for disposing the fan module 200, that is, no other devices such as a camera or display device can be disposed in the second cavity 40.

[0120] In some examples, the fan insertion port 50 can be oriented perpendicularly 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.

[0121] FIG. 7 is a schematic diagram of another mobile terminal provided by an embodiment of the present application.

[0122] As shown in FIG. 7, in some examples, the fan insertion port 50 can be oriented perpendicularly to the thickness direction of the mobile terminal and obliquely to the length direction and the width direction of the mobile terminal, that is, the first direction can be perpendicular to the thickness direction of the mobile terminal and oblique to the length direction and the width direction of the mobile terminal.

[0123] In some examples, the cross-sectional dimension of the fan mounting cavity 110 at the end away from the fan socket 50 is smaller than the dimension of the fan socket 50, so that the depth of insertion of the fan module 200 into the fan mounting cavity 110 can be limited by the cavity wall of 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 socket 50 to the end away from the fan socket 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 cross-section of the fan mounting cavity 110 perpendicular to the first direction.

[0124] Fig. 8 is a schematic view of one perspective of a mobile terminal according to an embodiment of the present application, and Fig. 9 is a schematic view of another perspective of the mobile terminal according to an embodiment of the present application. In Figs. 8 and 9, the fan module 200 is removed along the x direction, and the surface of the first structure 100 exposed for contact with the fan module 200 is the inner wall of the first structure 100.

[0125] As shown in Figs. 8 and 9, in some examples, the fan socket 50 can be oriented in the thickness direction of the mobile terminal, that is, the first direction is the thickness direction of the mobile terminal.

[0126] Fig. 10 is a schematic view of the second direction side of a mobile terminal according to an embodiment of the present application in a fan-locked state and with the fan module in an inserted position, and Fig. 11 is a schematic view of the second direction side of the mobile terminal according to an embodiment of the present application in a fan-unlocked state and with the fan module in an extended position. In the figures, 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.

[0127] As shown in Figs. 10 and 11, in some possible implementations, the first structure 100 is provided with a locking mechanism 300. When the mobile terminal is in the fan-locked state, the locking mechanism 300 locks and fixes the fan module 200 with the first structure 100. When the mobile terminal is in the fan-unlocked state, the locking mechanism 300 releases the fixing of the fan module 200 with the first structure 100.

[0128] In this way, the locking mechanism 300 is easier to set. In addition, when the fan module 200 is extended to the outside of the housing assembly 1, the locking mechanism 300 is less likely to be damaged due to exposure.

[0129] In some examples, 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. One end of the connecting rod 320 is fixedly connected with the locking tongue 310, the other end of the connecting rod 320 is fixedly connected with one end of the rotating rod 330, the rotating shaft 340 is arranged between the two ends of the rotating rod 330, the two ends of the rotating shaft 340 extend along the second direction, the rotating rod 330 is rotatably connected with the first structural member 100 through the rotating shaft 340, and the rotating rod 330 is connected with the first structural member 100 through the first spring 350. The side of the fan module 200 in the third direction is provided with a locking groove 223 matched with the locking tongue 310. When the mobile terminal is in the fan locking state, the locking tongue 310 is located at the locking position and is inserted into the locking groove 223, so that the fan module 200 is locked and fixed with the first structural member 100. When the mobile terminal is in the fan unlocking state, the locking tongue 310 is rotated around the rotating shaft 340 to the unlocking position outside the locking groove 223, so that the fan module 200 is released from the first structural member 100. The first spring 350 is used to drive the locking tongue 310 located at the unlocking position to rotate to the locking position.

[0130] The fan module 200 includes an insertion end (not shown), which is an end of the fan module 200 away from the fan insertion port 50 on the side of the fan mounting cavity 110.

[0131] For example, during the movement of the fan module 200 from the extended position to the inserted position, the part of the insertion end used to abut against the locking tongue 310 located at the locking position is a bevel, so as to push the locking tongue 310 to rotate from the locking position to the unlocking position, so that when the locking groove 223 moves to the position of the locking tongue 310, the locking tongue 310 can be inserted into the locking groove 223.

[0132] For example, during the movement of the fan module 200 from the extended position to the inserted position, the part of the locking tongue 310 located at the locking position used to abut against the insertion end is an arc surface, so as to facilitate the insertion end to push the locking tongue 310 to rotate from the locking position to the unlocking position during the movement of the fan module 200 from the extended position to the inserted position.

[0133] In some examples in which the first structural member 100 is provided with the locking mechanism 300, the first structural member 100 is further provided with an unlocking mechanism 500, the unlocking mechanism 500 is drivingly connected with the locking mechanism 300, and the unlocking mechanism 500 is used to switch the mobile terminal from the fan locking state to the fan unlocking state after receiving an unlocking signal.

[0134] In some examples in which the locking mechanism 300 includes the locking tongue 310, the connecting rod 320, the rotating rod 330, the rotating shaft 340, and the first spring 350, the unlocking mechanism 500 can include a push rod 510 extending in the first direction at two ends, the first structure 100 can be provided with a push rod slide 120 extending in the first direction at two ends, the push rod 510 is slidingly assembled in the push rod slide 120, the shell assembly 1 has a first insertion hole 60 communicating the push rod slide 120 and the outside of the shell 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, the other end of the push rod 510 is opposite to the first insertion hole 60, the first insertion hole 60 can be passed through by a plug pin, after the plug pin passes through the first insertion hole 60, the plug pin can push the push rod 510 to slide to apply an unlocking signal to the push rod 510, the push rod 510 pushed by the plug pin can push the rotating rod 330 to rotate to rotate the locking tongue 310 from the locking position to the unlocking position, thereby enabling the mobile terminal to switch from the fan locking state to the fan unlocking state.

[0135] For example, the first insertion hole 60 is provided with an elastic sealing piece 61, and the elastic sealing piece 61 has a communication hole for passing through the plug pin. When the communication hole is not provided with the plug pin, the elastic sealing piece 61 can press the hole wall of the communication hole to seal the communication hole. When the plug pin is inserted into the first insertion hole 60, the elastic sealing piece 61 can be deformed under the action of the plug pin to open the communication hole, so that the plug pin can pass through the communication hole. When the plug pin is inserted into the communication hole, the hole wall of the communication hole is pressed against the side wall of the plug pin to seal the plug pin and the communication hole. In this way, the sealing of the shell assembly 1 is not easily damaged by the first insertion hole 60.

[0136] In some possible embodiments, the shell assembly 1 is further provided with a push-out mechanism 400. At least part of the push-out mechanism 400 is located in the fan mounting cavity 110. The push-out mechanism 400 is used to push out the part of the fan module 200 in the inserted position to the outside of the shell assembly 1 through the fan insertion hole 50.

[0137] In this way, the fan module 200 can be easily extended from the fan mounting cavity 110. By using the push-out mechanism 400 to push out the fan module 200, the fan module 200 can be pulled out without using hands, and has good automatic ejection user experience and reliability.

[0138] Exemplarily, the ejecting mechanism 400 can comprise a second spring 410, one end of the second spring 410 being connected with the first structural member 100, and the other end of the second spring 410 being 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 locking state, the second spring 410 is in the compressed state. When the mobile terminal is in the fan unlocking state, the elastic restoring force generated by the second spring 410 is used to push the part of the fan module 200 in the insertion position out of the housing assembly 1 through the fan insertion port 50.

[0139] Exemplarily, the ejecting mechanism 400 can further comprise a push plate 420, one end of the second spring 410 being connected with the first structural member 100, and the other end of the second spring 410 being connected with the push plate 420, the second spring 410 being 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.

[0140] In some possible embodiments, the fan mounting cavity 110 is further provided with a position detection device 620, the position detection device 620 being used to detect whether the fan module 200 is in the insertion position. The position detection device 620 can be electrically connected with the main board 3 through a cable, and then can be electrically connected with a controller (not shown) electrically connected with the main board 3, the controller can be used to acquire the detection information obtained by the position detection device 620, and determine whether the fan module 200 is in the insertion position according to the detection information. The controller can also be used to issue a control instruction for indicating that the fan module 200 is not in the insertion position when the fan module 200 is not in the insertion position. The control instruction can be used to control the audible and visual alarm, the display screen 2 and the like to alarm.

[0141] Exemplarily, the position detection device 620 can comprise but is not limited to a distance sensor, a pressure sensor and the like.

[0142] 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.

[0143] 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 ejecting mechanism 400 comprises the 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, 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 when the fan module 200 is in the insertion position.

[0144] In some possible implementations, the fan module 200 includes a cover plate 210 and a fan assembly 220, which can be used to actively cool and dissipate heat from the mobile terminal. The cover plate 210 is fixedly arranged 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 the fan socket 50, and the cover plate 210 is located outside 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 orthogonal 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 socket 50. When the fan module 200 moves between the inserted position and the extended position in the first direction, at least part of the fan assembly 220 extends to the outside of the housing assembly 1 through the fan socket 50, or at least part of the fan assembly 220 is inserted into the fan mounting cavity 110 through the fan socket 50.

[0145] In this way, the cover plate 210 can limit the depth of the fan module 200 inserted into the fan mounting cavity 110.

[0146] In some examples in which the housing assembly 1 has a first insertion hole 60 for the insertion of the insertion pin, the cover plate 210 has a second insertion hole 211 opposite the first insertion hole 60, and the insertion pin can extend into the push rod slide 120 through the second insertion hole 211 and the first insertion hole 60 to push the push rod 510.

[0147] In some possible implementations, the mobile terminal further includes a first sealing ring 610 arranged between the cover plate 210 and the outer surface of the housing assembly 1, and the first sealing ring 610 surrounds the fan socket 50 in a circumferential direction of the fan socket 50. When the fan module 200 is in the inserted position, the first sealing ring 610 is compressed between the cover plate 210 and the outer surface of the housing assembly 1, and the first sealing ring 610 seals the connection between the fan module 200 and the housing assembly 1 at the fan socket 50.

[0148] In this way, when the fan module 200 is in the inserted position, the sealing performance of the mobile terminal is better, and the sealing performance of the housing assembly 1 is not easily damaged due to the opening of the fan socket 50.

[0149] The fan module 200 can be provided with a waterproof and dustproof assembly.

[0150] In some examples, the waterproof and dustproof assembly of the fan module 200 can include a first sealing ring 610, which can be fixedly arranged on the cover plate 210.

[0151] In this way, the fan assembly 220 is easier to insert and pull out at the fan socket 50.

[0152] In other examples, the first sealing ring 610 can be fixedly arranged on the housing assembly 1.

[0154] As shown in Fig. 12, in another example in which the locking mechanism 300 includes the lock tongue 310, the connecting rod 320, the rotating rod 330, the rotating shaft 340 and the first spring 350, the unlocking mechanism 500 includes a push rod 510 extending in the first direction at two ends, the first structural member 100 is provided with a push rod slide 120 extending in the first direction at two ends, the push rod 510 is slidingly assembled in the push rod slide 120, and the shell assembly 1 has a first insertion hole 60 communicating the push rod slide 120 and the outside of the shell assembly 1. The unlocking mechanism 500 further includes a button 520 arranged in the first insertion hole 60, one end of the push rod 510 is arranged 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 with the button 520. A user can press the button 520 to apply an unlocking signal to the button 520, the pressed button 520 can push the push rod 510 to slide, and the push rod 510 pushed by the button 520 can push the rotating rod 330 to rotate, so as to rotate the lock tongue 310 from the locking position to the unlocking position, and thus the mobile terminal can be switched from the fan locking state to the fan unlocking state.

[0155] Fig. 13 is a schematic view of the second direction side of another mobile terminal in the fan locking state and the fan module in the inserted position according to an embodiment of the present application.

[0156] As shown in Fig. 13, in another example in which the locking mechanism 300 includes the lock tongue 310, the connecting rod 320, the rotating rod 330, the rotating shaft 340 and the first spring 350, the unlocking mechanism 500 includes an electromagnet 530 and a magnetic member 540, the electromagnet 530 is fixedly connected with the first structural member 100, and the magnetic member 540 is fixedly arranged at the end of the rotating rod 330 away from the connecting rod 320. When the mobile terminal is in the fan locking state, the electromagnet 530 is powered off and is attracted to the magnetic member 540. A user can apply an unlocking signal to the electromagnet 530 by powering the electromagnet 530, the powered electromagnet 530 generates a magnetic repulsion force pushing the magnetic member 540 away, the magnetic member 540 pushed away by the magnetic repulsion force generated by the electromagnet 530 drives the rotating rod 330 to rotate, so as to rotate the lock tongue 310 from the locking position to the unlocking position, and thus the mobile terminal can be switched from the fan locking state to the fan unlocking state.

[0157] Fig. 14 is a schematic view of another mobile terminal according to an embodiment of the present application.

[0158] As shown in FIG. 14, in some examples, the locking mechanism 300 is an elastic locking mechanism 300, which is deformed under the action of an unlocking force to switch the mobile terminal from the fan locking state to the fan unlocking state. The unlocking force is the force exerted by the fan module 200 moving in the first direction on the locking mechanism 300, and the unlocking force is greater than the elastic restoring force generated by the locking mechanism 300 when the locking mechanism 300 is deformed to unlock the fan module 200 from the first structure 100. In this way, when the fan module 200 is inserted or pulled out, no special unlocking operation is required, and the fan module 200 can be conveniently inserted or pulled out.

[0159] In some examples where the locking mechanism 300 is an elastic locking mechanism 300, the locking mechanism 300 includes an elastic locking assembly 360, and the first structure 100 is provided with a lock ball slide 130 corresponding to the elastic locking assembly 360. One end of the lock ball slide 130 is in communication with the fan mounting cavity 110, and the other end of the lock ball slide 130 is a closed structure. The elastic locking assembly 360 includes a third spring 362 and a locking ball 361. The locking ball 361 of the elastic locking assembly 360 is slidingly assembled in the corresponding lock ball slide 130. One end of the third spring 362 of the elastic locking assembly 360 abuts the end of the corresponding lock ball slide 130 away from the fan mounting cavity 110, and the other end abuts the locking ball 361. The end of the lock ball slide 130 in communication with the fan mounting cavity 110 is provided with a limiting ring (not shown), and part of the locking ball 361 can extend into the fan mounting cavity 110 through the limiting ring. The limiting ring is used to limit the locking ball 361 from coming out of the lock ball slide 130. The fan mounting cavity 110 is provided with the elastic locking assembly 360 on at least one side in the third direction, and 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.

[0160] When the mobile terminal is in the fan locking state, part of the locking ball 361 of the elastic locking assembly 360 is located in the fan mounting cavity 110 and extends into the corresponding locking groove 223 to lock and fix the fan module 200 to the first structure 100. Under the action of the unlocking force, the locking ball 361 compresses the third spring 362, and at least part of the locking ball 361 is retracted into the corresponding lock ball slide 130 to move out of the corresponding locking groove 223, so that the mobile terminal is switched from the fan locking state to the fan unlocking state. During the movement of the fan module 200 from the extended position to the inserted position, the third spring 362 is first compressed, causing at least part of the locking ball 361 to retract into the corresponding lock ball slide 130. After the fan module 200 moves to the inserted position, part 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.

[0161] In some examples, the elastic locking assembly 360 further comprises a ball seat 363, which is arranged between the third spring 362 and the locking ball 361, and can be fixedly connected with the third spring 362. The ball seat 363 is in sliding fit with the locking ball slide 130, and 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 in the locking ball slide 130.

[0162] FIG. 15 is a schematic view of another mobile terminal according to an embodiment of the present application.

[0163] As shown in FIG. 15, in some examples where the locking mechanism 300 is an elastic locking mechanism 300, the locking mechanism 300 comprises a locking spring leaf 370, and the inner wall of the first structural member 100 is provided with a spring leaf groove 140 corresponding to the locking spring leaf 370.

The spring arm segment 371 is located in the corresponding spring leaf groove 140, and one end of the spring arm segment 371 is fixedly connected with the groove wall on the side of the corresponding spring leaf groove 140 away from the fan socket 50 in the first direction, and the other end of the spring arm segment 371 is fixedly connected with the locking segment 372. At least one side of the fan mounting cavity 110 in the third direction is provided with the locking spring leaf 370, and the side surface of the fan module 200 in the third direction is provided with a locking groove 223 corresponding to the locking spring leaf 370.

[0164] When the mobile terminal is in the fan locking state, part of the locking segment 372 of the locking spring leaf 370 is located in the fan mounting cavity 110 and extends into the corresponding locking groove 223, so as to lock and fix the fan module 200 with the first structural member 100. Under the action of the unlocking force, the spring arm segment 371 will deform along the third direction away from the fan module 200, so that the locking segment 372 moves out of the corresponding locking groove 223, so as to switch the mobile terminal from the fan locking state to the fan unlocking state. During the movement of the fan module 200 from the extended position to the inserted position, the spring arm segment 371 will first deform along the third direction away from the fan module 200, so that at least part of the locking segment 372 retracts into the corresponding spring leaf groove 140. After the fan module 200 moves to the inserted position, part of the locking segment 372 will move into the fan mounting cavity 110 and extend into the corresponding locking groove 223 under the action of the elastic restoring force of the spring arm segment 371.

[0165] For example, the side of the locking segment 372 close to the fan socket 50 and the side of the locking segment 372 away from the fan socket 50 are both inclined surfaces, so as to facilitate the movement along the third direction under the abutment of the fan module 200 moving in the first direction.

[0168] The electric telescopic rod 430 can be electrically connected with the controller through the main board 3 and controlled by the controller.

[0177] FIG. 20 is a view of the connection between the pull rod and the first structural member of the mobile terminal of FIG. 17, taken in the second direction.

[0178] As shown in Fig. 20, and with reference to Figs. 17-19, the first structural member 100 has a pressure plate slide 160 extending in the second direction, and a pressure plate 384 is slidably fitted 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 in the sliding hole, the first insertion section 382 can slide relative to the first structural member 100 in the second direction, and the first insertion section 382 is rotationally connected with the first structural member 100.

[0179] When the mobile terminal is in the fan locking state, the second insertion section 383 is located in the fourth groove section 394 and at an end of the fourth groove section 394 connected with the third groove section 393, and the fan module 200 is locked and fixed with the first structural member 100 through the pull rod 380 and the sliding block 440.

[0180] When it is needed to move the fan module 200 from the insertion position to the extended position, the sliding block 440 can be driven to move by pressing the fan module 200 in the first direction, due to the blocking of the second step structure 397 and the third step structure 398, the second insertion section 383 slides into the fifth groove section 395 from the fourth groove section 394 and slides toward the first groove section 391, so that the pull rod 380 is unlocked with the sliding block 440, the third spring 362 drives the sliding block 440 to drive the fan module 200 to extend, and the second insertion section 383 can slide along the fifth groove section 395 and the first groove section 391 to an end of the first groove section 391 away from the fan port 50.

[0181] When it is needed to move the fan module 200 from the extended position to the insertion position, the sliding block 440 can be driven to move by pressing the fan module 200 in the first direction, due to the blocking of the fourth step structure 399 and the first step structure 396, the second insertion section 383 slides into the third groove section 393 from the first groove section 391 and the second groove section 392, and moves along the third groove section 393 to an end of the fourth groove section 394 connected with the third groove section 393, so that the fan module 200 can be locked and fixed in the insertion position.

[0183] In some other possible embodiments, the fan module 200 is provided with a locking mechanism 300. When the mobile terminal is in the fan locking state, the locking mechanism 300 locks and fixes the fan module 200 with the first structural member 100. When the mobile terminal is in the fan unlocking state, the locking mechanism 300 releases the fixing between the fan module 200 and the first structural member 100.

[0184] In some examples, when the mobile terminal is in the fan unlocking state, the fan module 200 can be completely pulled out of the fan socket 50, that is, the fan module 200 can be separated from the housing assembly 1.

[0185] FIG. 21 is a schematic view of the fan module of another mobile terminal in an extended position according to an embodiment of the present application.

[0186] As shown in FIG. 21, in some other examples, when the mobile terminal is in the fan unlocking state, the fan module 200 cannot be completely pulled out of 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 in the fan mounting cavity 110. Specifically, the fan module 200 can be fixedly provided with an anti-disengagement structure 630, which is located in the fan mounting cavity 110 and 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 limit the fan module 200 inserted in the fan mounting cavity 110 from being disengaged from the housing assembly 1 through the fan socket 50.

[0187] In this way, the fan module 200 can be kept in the state of being partially extended from the housing assembly 1 and connected to the housing assembly 1, so as to facilitate heat dissipation of the mobile terminal through the fan module 200 partially extended from the housing assembly 1.

[0188] Exemplarily, the cavity wall of the fan mounting cavity 110 is provided with a sliding groove structure (not shown) for the anti-disengagement structure 630 to slide in the first direction, and the anti-disengagement structure 630 is inserted in the sliding groove structure.

[0189] FIG. 22 is a schematic view of another mobile terminal according to an embodiment of the present application.

[0190] As shown in FIG. 22, the mobile terminal further includes power supply devices and electrical connection devices 5. The power supply devices are arranged in the first device mounting cavity 31, and part of the electrical connection devices 5 is located in the first device mounting cavity 31 and part is located in the fan mounting cavity 110.

[0191] 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 through the electrical connection device 5.

[0192] In this way, the fan module 200 in the inserted position can be powered by the power supply device arranged in the first device mounting cavity 31 to drive the fan module 200 when the fan module 200 is in the inserted position. When the fan module 200 is in the inserted position, the overall anti-falling performance of the mobile terminal is good, and the appearance of the mobile terminal does not change.

[0193] 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 through the electrical connection device 5.

[0194] In this way, the fan module 200 in the extended position can be powered by the power supply device arranged in the first device mounting cavity 31 to drive the fan module 200 when the fan module 200 is in the inserted position. When the fan module 200 is in the extended position, the air inlet resistance is small, the air inlet volume is large, and the heat dissipation efficiency is high. In addition, when the fan module 200 in the extended position operates to dissipate heat, the space in the fan mounting cavity 110 becomes larger, which helps to reduce the flow pressure drop in the fan mounting cavity 110 and reduce the flow resistance in the fan mounting cavity 110, and the pressure head of the fan module 200 can be improved.

[0195] For heavy load high performance demand services, the fan module 200 can be automatically popped out of the housing assembly 1 by manual or based on software temperature reporting. When the fan module 200 is in the extended position, the fan module 200 can operate, which can expose the air inlet of the fan module 200 in the inserted position to the atmosphere in the fan mounting cavity 110, greatly increase the air inlet area of the fan module 200 while reducing the air inlet flow resistance, and significantly improve the performance of the fan module 200, thereby supporting high load high power consumption applications. After the fan module 200 is retracted to the inserted position in the housing assembly 1, the mobile terminal has better overall anti-falling performance.

[0196] The power supply device can include, but is not limited to, the main board 3, the battery 4, the controller, etc.

[0197] For example, the fan module 200 can be electrically connected to the main board 3 through the electrical connection device 5, the battery 4 can supply power to the fan module 200 through the main board 3, and the controller can control the fan module 200 through the main board 3. In this way, the power supply and control of the fan module 200 are more convenient.

[0198] In some possible embodiments, the electric connection device 5 comprises electric contact terminals 170 fixedly arranged on the first structural member 100, and the fan module 200 has first electric contact portions 224. The electric contact terminals 170 comprise second electric contact portions 171 located in the fan mounting cavity 110 and connecting portions 172 located in the first device mounting cavity 31 and electrically connected with the power supply device. The first electric contact portions 224 are configured to electrically contact with the second electric contact portions 171, so that the fan module 200 is electrically connected with the power supply device through the electric contact terminals 170.

[0199] In this way, the electric connection of the fan module 200 with the power supply device is facilitated. In addition, the electric connection device 5 has less influence on the movement of the fan module 200.

[0200] In some examples, when the fan module 200 is in the inserted position, the first electric contact portions 224 are located in the fan mounting cavity 110 and electrically contact with the second electric contact portions 171, and the fan module 200 is electrically connected with the power supply device through the electric contact terminals 170.

[0201] In this way, the electric connection of the fan module 200 with the power supply device is facilitated when the fan module 200 is in the inserted position.

[0202] In some examples, when the fan module 200 is in the extended position, the first electric contact portions 224 are located in the fan mounting cavity 110 and electrically contact with the second electric contact portions 171, and the fan module 200 is electrically connected with the power supply device through the electric contact terminals 170.

[0203] In this way, the electric connection of the fan module 200 with the power supply device is facilitated when the fan module 200 is in the extended position.

[0204] FIG. 23 is a schematic view of a fan module of a mobile terminal according to an embodiment of the present application before the fan module is inserted into a fan mounting cavity.

[0205] As shown in FIG. 23, in some examples, the first electric contact portions 224 are located on the surface of one side of the fan module 200 in the second direction, and the first electric contact portions 224 can be conductive contact patch structures, and the second electric contact portions 171 can be conductive spring structures.

[0206] In other examples, the insertion end of the fan module 200 has an insertion port, the first electric contact portions 224 are conductive spring structures arranged in the insertion port, and the second electric contact portions 171 are conductive pin structures arranged on the side of the fan mounting cavity 110 opposite the fan insertion port 50. When the fan module 200 is in the inserted position, the conductive pins are inserted into the insertion port and electrically contact with the conductive spring structures in the insertion port.

[0207] In some examples, the edge of the insertion interface is provided with a second sealing ring (not shown), and the waterproof and dustproof assembly of the fan module 200 can include the second sealing ring, which is compressed by the fan module 200 and the first structure 100 when the fan module 200 is in the insertion position, and which seals the connection between the fan module 200 and the first structure 100 at the insertion interface, so that the conductive spring structure in the insertion interface and the conductive insertion pin in electrical contact are in a sealed space.

[0208] 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 to the plurality of electrical contact terminals 170, the plurality of electrical contact terminals 170 including positive terminals, negative terminals, and signal terminals, and the plurality of first electrical contact portions 224 including positive electrical contact portions, negative electrical contact portions, and signal electrical contact portions corresponding to the signal terminals, the positive terminals being configured to be in electrical contact with the positive electrical contact portions, the negative terminals being configured to be in electrical contact with the negative electrical contact portions, and the signal terminals being configured to be in electrical contact with the signal electrical contact portions.

[0209] The distance between the positive terminals and the negative terminals can be greater than or equal to 1 mm. For example, the distance between the positive terminals and the negative terminals can be greater than or equal to 5 mm, so as to reduce the risk of short circuit between the positive terminals and the negative terminals.

[0210] The distance between the positive electrical contact portions and the negative electrical contact portions can be greater than or equal to 1 mm. For example, the distance between the positive electrical contact portions and the negative electrical contact portions can be greater than or equal to 5 mm.

[0211] In some examples, the controller can be configured to obtain the impedance between the positive terminals and the negative terminals, and determine whether the fan mounting cavity 110 is flooded based on the impedance between the positive terminals and the negative terminals. The controller can also be configured to issue a control instruction for indicating to stop or reduce the voltage supplied to the fan module 200 when it is determined that the fan mounting cavity 110 is flooded, for example, the control instruction can be used to increase the impedance threshold of the affected function.

[0212] In some examples, the surfaces of the electrical contact terminals 170 and the first electrical contact portions 224 have an anti-corrosion plating layer to improve the service life of the electrical contact terminals 170 and the first electrical contact portions 224.

[0213] In some examples, at least one of the positive terminals and the negative terminals is provided with a protection circuit between the power supply device, and the protection circuit is configured to limit the current or voltage when the electrical connection between the positive terminals and the negative terminals is abnormal, so as to avoid short circuit of the positive terminals and the negative terminals.

[0214] The positive terminal and the negative terminal can be electrically connected with the controller, the controller can be configured to acquire the voltage or current at the positive terminal and the negative terminal, and the controller can be configured to send an instruction indicating an abnormal electrical connection when the voltage or current at the positive terminal and the negative terminal is not in a preset range, so as to remind a user to clean and maintain.

[0215] In some possible embodiments, the electrical connection between the fan module 200 and the electrical connection device 5 is disconnected when the fan module 200 is not in the inserted position. At this time, the controller can determine whether the fan module 200 is in the inserted position by determining 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.

[0216] In some possible embodiments, the electrical connection between the fan module 200 and the electrical connection device 5 is disconnected when the fan module 200 is not in the extended position. At this time, the controller can determine whether the fan module 200 is in the extended position by determining 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.

[0217] FIG. 24 is a schematic view of the fan module of the mobile terminal in the inserted position according to another embodiment of the present application, and FIG. 25 is a schematic view of the fan module of the mobile terminal in the extended position according to another embodiment of the present application.

[0218] As shown in FIGS. 24 and 25, in some possible embodiments, the fan module 200 is electrically connected with the power supply device through the electrical connection device 5 when the fan module 200 moves to any position between the inserted position and the extended position along the first direction.

[0219] In this way, the fan module 200 in any position between the inserted position and the extended position can be powered, so that the fan module 200 in any position between the inserted position and the extended position can operate to dissipate heat. In addition, the fan module 200 can be controlled when the fan module 200 moves between the inserted position and the extended position.

[0220] In the example in which the fan module 200 is electrically connected with the power supply device through the electrical connection device 5 when the fan module 200 moves to any position between the inserted position and the extended position along the first direction, the fan module 200 and the fan mounting cavity 110 can constitute a variable air duct, and the controller can control the fan module 200 in the extended position to operate or stop operating.

[0221] For example, when the fan module 200 is in the extended position, the controller can send a control instruction to the display screen 2 to display whether to control the fan module 200 to continue operating. After receiving a signal indicating that the fan module 200 is controlled to operate, the controller controls the fan module 200 to continue operating. After receiving a signal indicating that the fan module 200 is controlled to stop operating, the controller controls the fan module 200 to stop operating.

[0222] In some possible embodiments, at least one of the second electrical contact 171 and the first electrical contact 224 is a strip structure extending in the first direction. When the fan module 200 is in the extended position, part of the fan module 200 is located in the fan mounting cavity 110 and part of the fan module 200 extends to the outside of the housing assembly 1 through the fan socket 50, and at least part of the first electrical contact 224 is located in the fan mounting cavity 110. When the fan module 200 moves to any position between the inserted position and the extended position in the first direction, the first electrical contact 224 is in electrical contact with the second electrical contact 171.

[0223] In this way, the electrical connection between the fan module 200 and the power supply device can be achieved when the fan module 200 moves to any position between the inserted position and the extended position. In addition, the electrical connection device 5 has less effect on the movement of the fan module 200 in the fan mounting cavity 110.

[0224] For example, the second electrical contact 171 is a strip structure extending in the first direction, and when the fan module 200 is in the extended position, the first electrical contact 224 is located in the fan mounting cavity 110.

[0225] In this way, the first electrical contact 224 is less likely to be damaged by moving to the outside of the housing assembly 1.

[0226] In some examples in which the second electrical contact 171 is a strip structure extending in 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 can be provided with a third sealing ring (not shown). The third sealing ring is pressed between the fan module 200 inserted in the fan socket 50 and the inner wall of the fan socket 50, and the third sealing ring can be used to seal the connection between the fan module 200 inserted in the fan socket 50 and the inner wall of the fan socket 50.

[0227] In this way, the fan module 200 can be sealed at the fan socket 50 when the fan module 200 moves to any position between the inserted position and the extended position, and the fan mounting cavity 110 is less likely to be dusty or wet.

[0228] In some possible embodiments, the electric connecting device 5 can be a flexible printed circuit (FPC), which can be connected to the insertion end of the fan module 200. When the fan module 200 is in the inserted position, the part of the flexible printed circuit located inside the fan mounting cavity 110 can be bent and accommodated at the side of the insertion end of the fan module 200. In this way, the electric connection between the fan module 200 and the power supply device can be achieved when the fan module 200 is in any position between the inserted position and the extended position.

[0229] In some possible embodiments, the fan assembly 220 includes a fan 221 for actively cooling and dissipating heat of the mobile terminal. The cover plate 210 is fixedly arranged at one end of the fan 221 in the first direction. When the mobile terminal is in the fan-locked state, the fan 221 is locked and fixed with the first structural member 100. When the mobile terminal is in the fan-unlocked state, the fan 221 is released from the fixation with the first structural member 100, and at least part of the fan 221 can be extended to the outside of the housing assembly 1 through the fan socket 50 or at least part of the fan 221 can be inserted into the fan mounting cavity 110 through the fan socket 50. At this time, the fan 221 is electrically connected with the electric connecting device 5. When the fan module 200 has the first electric contact part 224, the fan 221 has the first electric contact part.

[0230] In this way, the fan module 200 has a relatively simple structure, and it is convenient to arrange a fan 221 with a large size, thereby facilitating the increase of the air volume of the fan 221.

[0231] FIG. 26 is a schematic view of a fan module according to an embodiment of the present application.

[0232] As shown in FIG. 26, in some possible embodiments, the fan assembly 220 can include a fan seat 222 and a fan 221 for actively cooling and dissipating heat of the mobile terminal. The cover plate 210 is fixedly arranged at one end of the fan seat 222 in the first direction. The fan 221 is fixedly arranged on the fan seat 222, and the fan 221 is arranged at one side of the fan seat 222 in the second direction. The fan seat 222 is used to carry the fan 221. When the mobile terminal is in the fan-locked state, the fan seat 222 is locked and fixed with the first structural member 100. When the mobile terminal is in the fan-unlocked state, the fan seat 222 is released from the fixation with the first structural member 100, and the fan seat 222 can drive the fan 221 to extend to the outside of the housing assembly 1 through the fan socket 50 or the fan seat 222 can drive the fan 221 to be inserted into the fan mounting cavity 110 through the fan socket 50.

[0233] In this way, the fan 221 can be completely extended to the outside of the housing assembly 1 when the fan assembly 220 is partially located in the fan mounting cavity 110, facilitating maintenance of the fan 221. In addition, it is also convenient to provide the fan assembly 220 with a heat dissipation structure 640 and other devices, so that the structure of the fan module 200 is more flexible.

[0234] For example, the heat dissipation structure 640 can include one or more of heat dissipation fins, heat pipes, vapor chambers, etc. The heat dissipation structure 640 can be used to improve the heat exchange efficiency during air cooling and improve the heat dissipation capacity of the heat generating device and the entire machine.

[0235] In some possible embodiments, the fan 221 is non-detachably connected with the fan seat 222, and the fan 221 cannot be removed from the fan seat 222.

[0236] In some other possible embodiments, the fan 221 is detachably connected with the fan seat 222.

[0237] In this way, the fan 221 can be removed from the fan seat 222 for daily maintenance or repair.

[0238] For example, the fan 221 can be detachably connected with the fan seat 222 by clamping, fastener connection, etc.

[0239] In some examples in which the fan assembly 220 includes the fan seat 222 and the fan 221, the fan seat 222 is electrically connected with the electrical connection device 5, and the fan 221 is electrically connected with the fan seat 222, so that the fan 221 can be electrically connected with the electrical connection device 5 through the fan seat 222. When the fan module 200 has the first electrical contact portion 224, the fan seat 222 can have the first electrical contact portion 224, and the fan 221 is electrically connected with the first electrical contact portion 224.

[0240] For example, the fan seat 222 can be in electrical contact with the fan 221 mounted on the fan seat 222 through a terminal.

[0241] In some examples in which the fan module 200 includes the anti-disengagement structure 630, the anti-disengagement structure 630 can be provided on the fan seat 222.

[0242] 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.

[0243] FIG. 27 is a schematic diagram of another mobile terminal provided by an embodiment of the present application.

[0244] As shown in FIG. 27, in some possible embodiments, the fan mounting cavity 110 is in communication with the first device mounting cavity 31, and the module air inlet and the module air outlet of the fan module 200 are located in the fan mounting cavity 110 and in communication with the fan mounting cavity 110 when the fan module 200 is in the inserted position.

[0245] In this way, the fan module 200 can drive the air in the first device mounting cavity 31 and the fan mounting cavity 110 to circulate and flow, and the temperature can be leveled. In addition, no air vents need to be arranged on the outer surface of the mobile terminal, and the appearance of the mobile terminal is not affected.

[0246] For example, the module air outlet of the fan module 200 can be directed to the heat generating device such as the chip 6, to form a jet heat exchange effect, so as to reduce the temperature of the heat generating device such as the chip 6.

[0247] In the example in which the fan mounting cavity 110 is in communication with 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 the first device mounting cavity 31 to replace the hot air in the first device mounting cavity 31, so as to improve the heat dissipation effect of the heat generating device in the first device mounting cavity 31.

[0248] FIG. 28 is a schematic diagram of another mobile terminal provided by an embodiment of the present application.

[0249] As shown in FIG. 28, in another possible embodiment, 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 through the heat conduction assembly 700. The fan module 200 has a module air inlet and a module air outlet. The module air inlet and the module air outlet are both in communication with the outside of the housing assembly 1.

[0250] At this time, the heat generating device can transfer heat to the first structural member 100, and the fan module 200 obtains fresh air from the outside of the housing assembly 1 to take away the heat on the first structural member 100.

[0251] In this way, the heat dissipation performance of the fan module 200 is good. In addition, when the fan module 200 is in the extended position, the sealing performance of the first device mounting cavity 31 is not affected, and the sealing performance of the first device mounting cavity 31 is good.

[0252] In the example that the fan mounting cavity 110 is isolated from the first device mounting cavity 31, the fan mounting cavity 110 and the first device mounting cavity 31 are located in two sets of independent sealing, waterproof and dustproof systems. The main board 3, the battery 4, the chip 6, the electrically connected part of the display screen 2 and the like are arranged in the sealing, waterproof and dustproof system of the first device mounting cavity 31 and are physically isolated from the fan mounting cavity 110. The heat generated by the main board 3, the battery 4, the chip 6 and the display screen 2 can be transferred to the first structural member 100 through the heat conduction assembly 700 and is dissipated to the external environment by the fan module 200 through forced convection, so that the mobile terminal has good heat dissipation performance.

[0253] The fan mounting cavity 110 and the first device mounting cavity 31 are located in two sets of independent sealing, waterproof and dustproof systems. When the fan module 200 is maintained or repaired daily or the waterproof function of the fan mounting cavity 110 fails, the sealing, waterproof and dustproof performance of the first device mounting cavity 31 in which the main board 3, the battery 4, the chip 6 and the electrically connected part of the display screen 2 are arranged is not affected. The devices in the first device mounting cavity 31 can work normally and reliably, so that the system fault tolerance design capability of the fan module 200 and the robustness of the system waterproof and dustproof are strong, and the daily maintenance and non-destructive repair of the fan module 200 are facilitated.

[0254] In some examples, the waterproof and dustproof level of the fan mounting cavity 110 is lower than that of the first device mounting cavity 31. In this way, the fan module 200 is easy to set and ventilate.

[0255] For example, the waterproof and dustproof level of the fan mounting cavity 110 can be IP57 or IP67, and the waterproof and dustproof level of the first device mounting cavity 31 can be IP68 or higher.

[0256] When the housing assembly 1 includes the decorative piece 20 and the first device mounting cavity 31 is in communication with the second device mounting cavity 41, the waterproof and dustproof level of the first device mounting cavity 31 refers to the waterproof and dustproof level of the whole cavity formed by the communication of the first device mounting cavity 31 and the second device mounting cavity 41.

[0257] In some examples, the heat conduction assembly 700 can include a thermal interface material 710. The heat generating devices such as the chip 6 can be connected to the first structural member 100 through the thermal interface material 710.

[0258] FIG. 29 is a schematic view of another mobile terminal provided by an embodiment of the present application.

[0259] As shown in FIG. 29, the main board 3 is provided with the first chip 6a and the second chip 6b, and the heat conduction assembly 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 member 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 second chip 6b is provided with the shielding cover 730 on the outer side. 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.

[0260] For example, the heat conduction plate 720 can include, but is not limited to, a heat plate, a graphite plate, a middle frame, etc.

[0261] In some examples, the heat conduction assembly 700 can include the heat conduction plate 720. The heat conduction plate 720 can be in an integrated structure with the first structural member 100. The heat conduction plate 720 can be connected to the heat generating device through the thermal interface material 710.

[0262] In some examples, the heat conduction assembly 700 can include the shielding cover 730. The shielding cover 730 can be in an integrated structure with the first structural member 100. The shielding cover 730 can be connected to the heat generating device through the thermal interface material 710.

[0263] FIG. 30 is a schematic diagram of another mobile terminal according to an embodiment of the present application.

[0264] As shown in FIG. 30, in some possible implementations, the first structural member 100 is fixedly connected with a heat dissipation structure 640. The heat dissipation structure 640 is located in the fan mounting cavity 110. The heat on the heat generating device can be transferred to the heat dissipation structure 640 through the first structural member 100. The fan module 200 can take away the heat on the heat dissipation structure 640 by obtaining fresh air from the outside of the housing assembly 1.

[0265] In this way, the heat conduction efficiency between the first structural member 100 and the heat dissipation structure 640 is high. The efficiency of the fan module 200 in dissipating heat from the first structural member 100 is high.

[0266] FIG. 31 is a schematic diagram of another mobile terminal according to an embodiment of the present application.

[0267] As shown in Figure 31, 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 for the heat dissipation structure 640 to dissipate heat.

[0268] Figure 32 is a schematic diagram of another mobile terminal provided in an embodiment of this application.

[0269] As shown in Figure 32, 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 connect the fan mounting cavity 110 to the outside of the housing assembly 1. When the fan module 200 is in the inserted position, both the module air inlet and the module air outlet are located within the fan mounting cavity 110. One of the module air inlet and the module air outlet communicates with the first vent 810 through the fan mounting cavity 110, and the other of the module air inlet and the module air outlet communicates with the second vent 820.

[0270] 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.

[0271] 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.

[0272] 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.

[0273] 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.

[0274] For example, a dustproof structure can be arranged at the first vent 810 and the second vent 820, so that dust is less likely to enter the fan module 200 and the fan mounting cavity 110, and in addition, dust removal of the dustproof structure is facilitated. The waterproof and dustproof assembly can include the dustproof structure.

[0275] For example, the dustproof structure can include a dustproof screen.

[0276] 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, and the rear cover 12 can have the second vent 820. At this time, the fan 211 of the fan module 200 can be a mechanical centrifugal fan that takes in air along the thickness direction of the mobile terminal and discharges air along a direction perpendicular to the air intake direction. In the high-power or high-performance mode, the fan module 200 can be extended out of the housing assembly 1, so that the air intake resistance is greatly reduced, high-performance air intake is achieved, the air flow through the heat dissipation structure 640 is larger, and the heat dissipation performance is better.

[0277] FIG. 33 is a schematic diagram of another mobile terminal according to an embodiment of the present application.

[0278] As shown in FIG. 33, in some possible embodiments, the housing assembly 1 has a first vent 810 that communicates the fan mounting cavity 110 with 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 in the fan mounting cavity 110 and communicates with the first vent 810 through the fan mounting cavity 110, and the other of the module air inlet and the module air outlet is located at an end of the fan module 200 that faces the outside of the housing assembly 1 along the first direction.

[0279] In this way, air can flow in and out of the fan mounting cavity 110 more smoothly, and the heat dissipation efficiency of the fan module 200 is higher. In addition, there are fewer openings on the housing assembly 1, and the appearance of the housing assembly 1 is less affected. In addition, the number of openings on the first structural member 100 can be reduced, and the need for an air duct formed by the first structural member 100 can be eliminated, so that the structure of the first structural member 100 is relatively simple.

[0280] For example, when the first vent 810 communicates with the module air outlet when the fan module 200 is in the inserted position, air in the external environment can flow through the module air inlet, pass through the fan 211, and reach the heat dissipation structure 640 to exchange heat, and then the air after heat exchange can flow out of the fan mounting cavity 110 through the first vent 810. Alternatively, air in the external environment can flow through the module air inlet, reach the heat dissipation structure 640 to exchange heat, and then flow out of the fan mounting cavity 110 through the fan 211 and the first vent 810.

[0281] For example, the first air vent 810 and the module air inlet and the module air outlet at the end of the fan module 200 along the first direction towards the outside of the shell assembly 1 can be provided with a dustproof structure, so that dust is not easy to enter the fan module 200 and the fan mounting cavity 110, and in addition, dust removal of the dustproof structure is facilitated.

[0282] In some possible implementation manners, the shell assembly 1 has a first air vent 810, which communicates the fan mounting cavity 110 with the outside of the shell assembly 1. When the fan module 200 is in the extended position, the module air inlet is located at the outside of the shell assembly 1, and the module air outlet is located in the fan mounting cavity 110 and communicates with the first air vent 810. When the fan module is in the inserted position, the module air inlet and the module air outlet are both located in the fan mounting cavity. In this way, when the fan module 200 is in the extended position, air in the external environment can flow through the fan mounting cavity 110 through the module air inlet, and flow back to the external environment through the first air vent 810, to perform active air cooling heat dissipation.

[0283] FIG. 34 is a schematic diagram of another mobile terminal provided by an embodiment of the present application.

[0284] As shown in FIG. 34, the first air vent 810 can be perpendicular to the second direction. For example, when the first structural member 100 is fixedly connected with the side 11, and the second direction is the thickness direction of the mobile terminal, the side 11 can have the first air vent 810. In this way, it is beneficial to reduce the thickness of the mobile terminal.

[0285] FIG. 35 is a schematic diagram of another mobile terminal provided by an embodiment of the present application.

[0286] As shown in FIG. 35, the first air vent 810 can be towards the second direction. For example, when the first structural member 100 is fixedly connected with the side 11, and the second direction is the thickness direction of the mobile terminal, the back cover 12 can have the first air vent 810. In this way, it is beneficial to reduce the length of the first structural member 100, and reduce the space occupied by the first structural member 100 in the shell assembly 1.

[0287] FIG. 36 is a schematic diagram of another mobile terminal provided by an embodiment of the present application.

[0288] As shown in FIG. 36, in some examples in which the first air vent 810 is located at the back cover 12, a projection of the first air vent 810 along the second direction is located within a projection of the fan module 200 along the second direction in the inserted position. In this way, it is beneficial to reduce the length of the first structural member 100, and reduce the space occupied by the first structural member 100 in the shell assembly 1.

[0289] FIG. 37 is a schematic diagram of another mobile terminal provided by an embodiment of the present application.

[0290] As shown in FIG. 37, in some examples where the first vent 810 is located at the rear cover 12, the projection of the first vent 810 along the second direction is located outside the projection of the fan module 200 along the second direction when the fan module 200 is in the inserted position. In this way, the air intake or air exhaust of the fan module 200 can be facilitated.

[0291] FIG. 38 is a schematic view of another mobile terminal according to an embodiment of the present application.

[0292] As shown in FIG. 38, in some possible implementations, the cover plate 210 of the fan module 200 has a third vent 830 and a fourth vent 840, one of which is the module air intake and the other of which is the module air exhaust. The fan 221 of the fan module 200 has a fan air intake and a fan air exhaust.

[0293] In some examples, one of the fan air intake and the fan air exhaust is in communication with the outside of the housing assembly 1 through the third vent 830. When the fan module 200 is in the inserted position, the other of the fan air intake and the fan air exhaust is located in the fan mounting cavity 110, and the fourth vent 840 communicates the fan mounting cavity 110 with the outside of the housing assembly 1.

[0294] In this way, the fresh air outside the housing assembly 1 can replace the air in the fan mounting cavity 110 through the third vent 830 and the fourth vent 840, thereby dissipating heat from the mobile terminal. In addition, no vent needs to be formed on the housing assembly 1, which does not affect the appearance of the housing assembly 1. In addition, the openings on the first structural member 100 and the need for the air duct formed by the first structural member 100 can be reduced, which can simplify the structure of the first structural member 100 and facilitate reducing the thickness of the mobile terminal.

[0295] FIG. 39 is a schematic view of another mobile terminal according to an embodiment of the present application.

[0296] As shown in FIG. 39, in some examples where the heat dissipation structure 640 is fixedly connected to the fan seat 222, the fan assembly 220 of the fan module 200 further includes a second structural member 225 fixedly arranged on the fan seat 222, the second structural member 225 being configured to form a module air duct 226, and the third vent 830 communicating the outside of the housing assembly 1 with the module air duct 226. One of the fan air intake and the fan air exhaust is in communication with the third vent 830 through the module air duct 226, and the other of the fan air intake and the fan air exhaust is in communication with the outside of the housing assembly 1 through the fourth vent 840, and the heat dissipation structure 640 is arranged in the module air duct 226.

[0297] In this way, the fresh air outside the shell assembly 1 can replace the air in the module air duct 226 through the third vent 830 and the fourth vent 840, thereby cooling the mobile terminal. In addition, no vent needs to be formed on the shell assembly 1, and the appearance of the shell assembly 1 is not affected. Furthermore, the opening on the first structural member 100 and the air duct formed by the first structural member 100 can be reduced, the structure of the first structural member 100 is relatively simple, and the thickness of the mobile terminal can be reduced. In addition, when the fan module 200 is in the extended position, the fan 221 can continue to cool the heat dissipation structure 640.

[0298] FIG. 40 is a schematic view of another mobile terminal according to an embodiment of the present application.

[0299] As shown in FIG. 40, in some examples, the fan assembly 220 includes a plurality of fans 221, and the cover plate 210 has a plurality of fourth vents 840 corresponding to the fans 221. One of the fan air inlet and the fan air outlet of each fan 221 is communicated with the third vent 830 through the module air duct 226, and the other of the fan air inlet and the fan air outlet of each fan 221 is communicated with the outside of the shell assembly 1 through the corresponding fourth vent 840. In this way, the fan module 200 has a better cooling effect.

[0300] In some possible embodiments, the fan module 200 is a piezoelectric fan module. That is, the fan 221 of the fan module 200 is a piezoelectric fan. In this way, the thickness of the piezoelectric fan is relatively small, the thickness of the fan module 200 is reduced, the size requirements of the shell assembly 1 and the fan socket 50 are reduced, and the fan module 200 is easily arranged on the mobile terminal. In addition, the air inlet and air outlet directions of the piezoelectric fan are flexible, the arrangement of the fan module 200 is flexible, and the piezoelectric fan has a large pressure head, so that the dustproof structure 650 with a waterproof and breathable film is easily arranged at the air inlet and air outlet ends.

[0301] In the example in which the fan module 200 is a piezoelectric fan module, the dustproof structure 650 with a waterproof and breathable film is arranged at the module air inlet and the module air outlet of the fan module 200. In this way, dust is not easily introduced into the fan module 200, and the piezoelectric fan which is sensitive to dust can be reliably operated.

[0302] For example, the dustproof structure 650 with a waterproof and breathable film can include a waterproof and breathable film and a dust screen, and the dust screen and the waterproof and breathable film are fixedly connected with the fan module 200, and the waterproof and breathable film is arranged at the inner side of the dust screen. That is, at the module air inlet, air first flows through the dust screen and then flows into the fan module 200 through the waterproof and breathable film. At the module air outlet, air in the fan module 200 first flows through the waterproof and breathable film and then flows out of the fan module 200 through the dust screen.

[0303] When the fan module 200 is a piezoelectric fan module, the waterproof and dustproof level of the fan mounting cavity 110 can be IP67 or a higher level.

[0304] In some other possible embodiments, 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, which can be a centrifugal fan.
