Description

Technical Field

[0001] This application relates to the field of mobile terminal technology, and in particular to a control method, device and mobile terminal for a mobile terminal. Background Technology

[0002] Mobile devices have become an indispensable information transmission medium in everyone's life; among them, screen breakage is the most common and most expensive form of damage to mobile devices, mainly caused by the impact of falling due to accidental slippage.

[0003] In related technologies, common methods to prevent mobile terminals from being damaged by drops include adding a protective case to the outside of the mobile terminal and attaching a protective film to the screen to disperse and absorb the impact force when the mobile terminal is dropped. In addition, there are also proposals to integrate protective devices inside the mobile terminal, which are automatically triggered when a drop is detected, thereby extending protective brackets from various parts of the outside of the mobile terminal to protect the fragile parts of the mobile terminal. However, all of the above methods will increase the size and weight of the mobile terminal, thus increasing its size, thickness and weight, which means sacrificing the slim design and handheld comfort of the mobile terminal. Summary of the Invention

[0004] The main objective of this application is to provide a control method, device, and mobile terminal for a mobile terminal, which aims to at least prevent the mobile terminal from being damaged by drops while ensuring a slim and lightweight design and comfortable handheld operation.

[0005] To achieve the above objectives, this application proposes a control method for a mobile terminal. The mobile terminal includes a device body, a switching device, a detection device, and a control device. A sealed cavity is formed within the device body, and a connecting hole is formed on the device body connecting the sealed cavity and the external environment. The switching device is disposed in the device body and is capable of opening and closing the connecting hole, having a closed state (closing the connecting hole) and an open state (opening the connecting hole). The detection device is used to detect the status data of the mobile terminal, and the control device is used to control the switching device to switch between the open state and the closed state. The control method for the mobile terminal includes: Obtain the status data detected by the detection device; If the mobile terminal is determined to be in an abnormal state based on the status data, the switch device is controlled to switch from the open state to the closed state.

[0006] This application also proposes a mobile terminal, which includes: The equipment body has a sealed cavity formed inside it, and a connecting hole is formed on the equipment body to connect the sealed cavity and the external environment; A switching device is disposed on the main body of the device and is capable of opening and closing the connecting hole, so as to have a closed state of closing the connecting hole and an open state of opening the connecting hole; A detection device, disposed on the main body of the device, is used to detect the status data of the mobile terminal; and, A control device is electrically connected to the switching device and the detection device, and controls the switching device to switch between the open state and the closed state based on the status data detected by the detection device.

[0007] This application also proposes a control device, which includes a memory, a processor, and a control program for a mobile terminal stored in the memory. The processor executes the control program for the mobile terminal to implement the steps of a control method for the mobile terminal.

[0008] In the technical solution of this application, before the main body of the device is subjected to a drop impact and deforms, the control device determines that the mobile terminal is in an abnormal state by detecting the status data detected by the detection device, and controls the switch device to switch from the open state to the closed state. At this time, because the sealing cavity is sealed, the deformation of the main body of the device will cause the volume of the sealing cavity to shrink, that is, the gas in the sealing cavity is compressed and the pressure increases, thereby forming a reverse thrust in the main body of the device. This reverse thrust can offset at least part of the impact force received by the mobile terminal at the moment of impact, thereby absorbing the impact energy and preventing the main body of the device from being damaged by a drop due to a large degree of deformation. Compared with the protection methods for mobile terminals in related technologies, this protection method does not require the addition of more additional protective parts, such as protective shells and protective brackets, thereby ensuring the thin and light design of the mobile terminal and the user's handheld comfort.

[0016] Mobile devices have become an indispensable information transmission medium in everyone's life; among them, screen breakage is the most common and most expensive form of damage to mobile devices, mainly caused by the impact of falling due to accidental slippage.

[0017] In related technologies, common methods to prevent mobile terminals from being damaged by drops include adding a protective case to the outside of the mobile terminal and attaching a protective film to the screen to disperse and absorb the impact force when the mobile terminal is dropped. In addition, there are also proposals to integrate protective devices inside the mobile terminal, which are automatically triggered when a drop is detected, thereby extending protective brackets from various parts of the outside of the mobile terminal to protect the fragile parts of the mobile terminal. However, all of the above methods will increase the size and weight of the mobile terminal, thus increasing its size, thickness and weight, which means sacrificing the slim design and handheld comfort of the mobile terminal.

[0018] In view of this, this application proposes a mobile terminal, Figures 1 to 6 These are some embodiments of this application.

[0019] Please see Figures 1 to 3 In some embodiments of this application, the mobile terminal includes a device body 1 and a switch device 2. A sealed cavity 3 is formed inside the device body 1, and a connecting hole 4 is formed on the device body 1 to connect the sealed cavity 3 and the external environment. The switch device 2 is disposed on the device body 1 and can open and close the connecting hole 4, so as to have a closed state with the connecting hole 4 closed and an open state with the connecting hole 4 open. When the switch device 2 opens the connecting hole 4, the sealed cavity 3 can communicate with the external environment through the connecting hole 4 to maintain the air pressure balance inside and outside the device body 1. When the switch device 2 closes the connecting hole 4, the sealed cavity 3 is isolated from the external environment.

[0020] Furthermore, the mobile terminal also includes a detection device and a control device. The detection device is disposed on the main body 1 of the device and is used to detect the status data of the mobile terminal. The control device is electrically connected to the switching device 2 and the detection device, and controls the switching device 2 to switch between the open state and the closed state according to the status data detected by the detection device. Specifically, the detection device can detect the status data of the mobile terminal. When the control device determines that the mobile terminal is in an abnormal state based on the status data detected by the detection device, it controls the switching device 2 to switch from the open state to the closed state, thereby isolating the sealed cavity 3 from the external environment.

[0021] In accordance with the above, in the technical solution of this application, before the main body 1 of the device is subjected to a drop impact and deforms, the control device determines that the mobile terminal is in an abnormal state based on the status data detected by the detection device, and controls the switch device 2 to switch from the open state to the closed state. At this time, because the sealing cavity 3 is sealed, the deformation of the main body 1 will cause the volume of the sealing cavity 3 to shrink, that is, the gas in the sealing cavity 3 is compressed and the pressure increases, thereby forming a reverse thrust in the main body 1. This reverse thrust can offset at least part of the impact force received by the mobile terminal at the moment of impact, thereby absorbing the impact energy and preventing the main body 1 from being damaged by a drop due to a large degree of deformation. Compared with the protection methods for mobile terminals in related technologies, this protection method does not require the addition of many additional protective parts, such as protective shells and protective brackets, thereby ensuring the thin and light design of the mobile terminal and the user's handheld comfort.

[0022] It should be noted that the specific type of mobile terminal in this application is not limited; it can be a tablet computer, a mobile phone, etc.

[0023] The reverse thrust described above will now be explained.

[0024] According to the ideal gas equilibrium equation: PV = nRT, where P is pressure, V is volume, n is the amount of substance of the gas, R is the ideal gas constant, and T is the thermodynamic temperature. The ideal gas equilibrium equation shows that pressure P is simultaneously affected by volume V, amount of substance n, and temperature T. When the amount of substance n and temperature T remain constant, an instantaneous change in volume V will cause a change in pressure P.

[0025] When the switch device 2 is in the closed state and the sealing cavity 3 is sealed, the amount of gas n is constant. When the mobile terminal is subjected to impact deformation, the volume inside the sealing cavity 3 will decrease. According to Boyle's law, P1V1=P2V2, the decrease in the volume inside the sealing cavity 3 will increase the pressure inside the sealing cavity 3. The increased pressure acts on the effective area of ​​the inner wall of the sealing cavity 3, forming a reverse thrust F. The reverse thrust F conforms to the formula F=PS, where P is the pressure and S is the area. This can offset part of the impact force on the mobile terminal, so as to avoid damage to key components when the mobile terminal is deformed by impact.

[0026] Please see Figures 2 to 4 In some embodiments of this application, the switching device 2 includes a driving part 21 and a switching element 22. The driving part 21 can drive the switching element 22 to move, so that the switching element 22 has an open position and a closed position. When the switching device 2 is in the closed state, the switching element 22 is in the closed position to block the communicating hole 4. When the switching device 2 is in the open state, the switching element 22 is in the open position to release the blockage of the communicating hole 4.

[0027] In this embodiment, the drive unit 21 can drive the switch element 22 to move, so that the switch element 22 switches between an open position and a closed position. When the switch element 22 is in the closed position, the switch element 22 can block the connecting hole 4, so that the switch device 2 is in the closed state. At this time, the sealed cavity 3 is isolated from the external environment, providing conditions for the mobile terminal to generate a reverse thrust by compressing the gas inside the sealed cavity 3 when it is dropped and impacted. When the switch element 22 is in the open position, the blockage of the connecting hole 4 is released, so that the switch device 2 is in the open state. At this time, the sealed cavity 3 is connected to the external environment, which can maintain the air pressure balance inside and outside the device body 1.

[0028] In some embodiments of this application, the switch device 2 is disposed within the sealed cavity 3; when the switch element 22 is in the closed position, the switch element 22 is located at the connection between the sealed cavity 3 and the connecting hole 4, thereby blocking the connecting hole 4; in this embodiment, the switch device 2 is integrated inside the sealed cavity 3, that is, the switch device 2 is not exposed from the outside of the device body 1, which is conducive to the overall thin and light design of the mobile terminal, and can also improve the aesthetics of the mobile terminal.

[0029] In some embodiments of this application, the switching device 2 further includes an elastic seal 23, which is disposed on the side of the switching member 22 facing the connecting hole 4. When the switching member 22 is in the closed position, the elastic seal 23 abuts against the device body 1 to block the connecting hole 4. In this embodiment, when the switching member 22 moves to the closed position, the elastic seal 23 abuts tightly against the device body 1, thereby achieving flexible sealing of the connecting hole 4 at the connection between the connecting hole 4 and the sealing cavity 3. Due to the elastic deformable structural characteristics of the elastic seal 23, it can generate adaptive deformation at the position where it contacts the device body 1, thereby completely fitting the inner wall of the sealing cavity 3. This can compensate for local deformation that may occur due to manufacturing tolerances or during long-term use of the mobile terminal, ensuring the sealing reliability of the sealing cavity 3 when the mobile terminal is impacted.

[0030] The form in which the elastic seal 23 is installed is not limited.

[0031] In one embodiment, the resilient seal 23 is provided in a sheet-like form. When the switch 22 is in the closed position, the resilient seal 23 can completely cover the connecting hole 4, thereby sealing the sealing cavity 3.

[0032] In another embodiment, the resilient seal 23 is arranged in a ring shape. When the switch 22 is in the open position, the resilient seal 23 abuts against the periphery of the connecting hole 4 and is arranged around the connecting hole 4 to cooperate with the switch 22 to seal the sealing cavity 3.

[0033] In one specific embodiment of this application, the switch 22 is plate-shaped to cooperate with the elastic seal 23 to ensure the sealing reliability of the sealing cavity 3 when the switch device is in the closed state.

[0034] In some embodiments of this application, the driving unit 21 includes an electromagnetic driving unit, which is fixedly disposed on the device body 1; the switching device 2 also includes a magnet 24 connected to the switching element 22, which can be driven to move by the electromagnetic driving unit, so that the switching element 22 can be driven to move by the electromagnetic driving unit; in this embodiment, the switching device uses electromagnetic driving to drive the switching element 22 to move, which can simplify the structural setting of the switching device 2, avoid the complex mechanical transmission structure built into the switching device 2, which would increase the size of the switching device 2, thereby ensuring the lightweight design of the mobile terminal.

[0035] It should be added that the electromagnetic drive unit can precisely control the direction of the magnetic field by changing the direction of the input current, thereby driving the magnet 24 to achieve controllable reciprocating motion on its active path.

[0036] In some embodiments of this application, the switching device 2 further includes a housing 25, which is fixedly disposed on the device body 1 and has a mounting groove with its opening facing the connecting hole 4. The electromagnetic drive unit and the magnet 24 are disposed within the housing 25, with the magnet 24 located on the side of the electromagnetic drive unit facing the groove. The switching element 22 is located between the housing 25 and the connecting hole 4 and is connected to the magnet 24 via a connector 26. In this embodiment, the switching device 2 encapsulates both the electromagnetic drive unit and the magnet 24 within the housing 25 to achieve integration and modularity of the switching device 2, facilitating assembly and maintenance.

[0037] Meanwhile, since the electromagnetic drive unit is placed inside the sealed cavity 3 and further encapsulated in the outer shell 25, it can effectively block the interference of the environment or structure inside the sealed cavity 3 on the electromagnetic drive unit, ensuring the stability of the electromagnetic drive unit's operation.

[0038] In some embodiments of this application, a guide rail is formed inside the housing 25, and the magnet 24 is movably disposed on the guide rail and can move along the guide rail under the drive of the electromagnetic drive unit. In this embodiment, the guide rail inside the housing 25 can provide precise guidance and constraint for the movement of the magnet 24, ensuring that the movement trajectory of the switch 22 remains stable and without deviation during its movement stroke, thereby achieving stability of the movement of the switch 22 when blocking and unblocking the connecting hole 4.

[0039] In some embodiments of this application, the switching device 2 further includes an elastic element 27 disposed between the magnet 24 and the inner wall of the housing 25, so as to drive the magnet 24 to move the switching element 22 from the closed position to the open position through its elastic force; wherein, the electromagnetic drive unit drives the magnet 24 to resist the elastic force of the elastic element 27 to move the switching element 22 from the open position to the closed position.

[0040] In this embodiment, by further adding an elastic element 27 within the switching device 2, the elastic element 27 can use its own elastic force to drive the magnet 24 to move and move the switch 22 from the closed position to the open position. When the electromagnetic drive unit is working, it drives the magnet 24 to resist the elastic force of the elastic element 27, causing the switch 22 to move from the open position to the closed position. The elastic element 27 ensures that the switch 22 automatically returns to the open position and maintains communication between the connecting hole 4 and the sealed cavity 3 when the switching device 2 is not powered on, thus ensuring pressure balance inside and outside the device body 1.

[0041] Meanwhile, the electromagnetic drive unit only starts working when the sealed cavity 3 needs to be sealed, so as to reduce the energy loss of the switching device 2.

[0042] The specific type of the elastic element 27 is not limited. The elastic element 27 can be a spring, an elastic washer, etc.

[0043] In some embodiments of this application, the mobile terminal further includes a pressurizing device disposed within the sealed cavity 3 to pressurize the sealed cavity 3 when the switching device 2 is in the closed state. In this embodiment, when the switching device switches from the open state to the closed state and the sealed cavity 3 is in a sealed state, the pressurizing device can actively inject gas into the sealed cavity 3 to increase the base pressure within the sealed cavity 3. Thus, the sealed cavity 3 can be pressurized before and during the moment of impact, allowing the sealed cavity 3 to generate a greater reverse thrust when the mobile terminal is deformed by the impact, thereby absorbing greater impact energy. This prevents the main body 1 from undergoing significant deformation and falling damage when the mobile terminal falls from a greater height or at a higher speed.

[0044] When the impact of the mobile terminal falling ends, the control device can control the switch to switch from the closed state to the open state, thereby releasing the internal air pressure of the sealed cavity 3 and balancing the air pressure inside and outside the main body of the device 1.

[0045] Furthermore, after the pressurizing device has released the gas, it can continue to compress the gas while the switching device is in the open state, so as to store the compressed gas inside.

[0046] In some embodiments of this application, the device body 1 includes a screen assembly 11 and a housing 12. The screen assembly 11 and the housing 12 enclose the sealed cavity 3. This structural design places the sealed cavity 3 close to the easily damaged screen assembly 11 in the mobile terminal. When the mobile terminal falls and causes the screen assembly 11 to collide with the outside, the sealing cavity 3 is sealed because the switching device 2 has already sealed it. The inward deformation of the screen assembly 11 will instantly compress the gas inside the sealed cavity 3, and the sealed cavity 3 can generate an outward reverse thrust. This reverse thrust can offset the force of the external impact on the screen assembly 11, efficiently absorb and dissipate the impact energy, and prevent the screen assembly 11 from being damaged by a fall due to a large degree of deformation.

[0047] In some embodiments of this application, the device body 1 includes a screen assembly 11, a mid-frame 121, and a back cover 122. The screen assembly 11 and the back cover 122 are located on opposite sides of the mid-frame 121 and are fixedly connected to the mid-frame 121. The device body 1 has at least one sealing cavity 3, which is correspondingly disposed with at least one of the screen assembly 11 and the back cover 122. In this embodiment, the sealing cavity 3 can be located close to the easily damaged screen assembly 11 and the back cover 122 in the mobile terminal. When the device is dropped and impacted, regardless of whether the impact force acts on the screen assembly 11 or the back cover 122, the corresponding sealing cavity 3 can be quickly sealed under the action of the switching device 2; subsequently, the inward deformation of the impacted component will release the gas in the sealing cavity 3, thereby generating a reverse thrust in the outward direction. This reverse thrust can offset the force of the external impact on the screen assembly 11 or the back cover 122, efficiently absorb and dissipate the impact energy, and prevent the screen assembly 11 or the back cover 122 from being damaged by drop due to a large degree of deformation.

[0048] In this embodiment, the back cover 122 is a glass back cover. Of course, the back cover 122 can also be made of other materials that are easily broken upon impact, and there is no limitation here.

[0049] Furthermore, in this embodiment, the number of sealing cavities 3 within the device body 1 is not limited. In one embodiment, a single sealing cavity 3 is provided, which is located near both the screen assembly 11 and the rear cover 122, so that the internal space of the sealing cavity 3 can be compressed to provide a reverse thrust when the screen assembly 11 and the rear cover 122 are deformed. In another embodiment, two sealing cavities 3 are provided, which are located near the screen assembly 11 and the rear cover 122 respectively, so that the internal space of the corresponding sealing cavity 3 can be compressed to provide a reverse thrust when the screen assembly 11 or the rear cover 122 is deformed.

[0050] Of course, the sealing cavity 3 can be formed by the screen assembly 11 or the back cover 122 in the above embodiments, or it can be formed by other structural components inside the mobile terminal. It is just to ensure that when the screen assembly 11 or the back cover 122 is deformed, the space inside the sealing cavity 3 can be compressed and provide a reverse thrust to the screen assembly 11 or the back cover 122.

[0051] In some embodiments of this application, the housing 12 includes a middle frame 121 and a rear cover 122.

[0052] It should be further explained that since the main body 1 of the device is formed by combining multiple components, such as the combination of the housing 12 and the screen assembly 11, the screen assembly 11, the middle frame 121 and the back cover 122, when the pressurizing device applies pressure to the sealing cavity 3 when the switch device 2 is in the closed state, it is necessary to ensure that the pressure in the sealing cavity 3 will not damage the connection between the housing 12 and the screen assembly 11 or the connection between the screen assembly 11, the middle frame 121 and the back cover 122.

[0053] In some embodiments of this application, the detection device includes an accelerometer sensor for detecting the acceleration value of the device body 1. In this embodiment, by setting an accelerometer sensor, the mobile terminal is determined to be in an abnormal state by detecting whether its acceleration value exceeds a set threshold. If the acceleration value exceeds the set threshold, the control device controls the switch device 2 to switch from an on state to a off state; if the acceleration value does not exceed the set threshold, the control device does not control the switch device 2 to operate.

[0054] In some embodiments of this application, the connecting hole 4 is a waterproof and breathable component of the mobile terminal. In this embodiment, the connecting hole 4, as a waterproof and breathable component of the mobile terminal, not only maintains the basic function of balancing the air pressure inside and outside the main body 1, but also works with the switch device 2 to achieve rapid sealing of the sealing cavity 3 during a drop impact. This allows the reverse thrust generated by the compression of internal gas to absorb the impact energy. This design eliminates the need for additional external protective structures on the mobile terminal, effectively ensuring the lightweight design and handheld comfort of the mobile terminal.

[0055] To prevent liquid from entering the sealed cavity 3 through the connecting hole 4, in some embodiments of this application, a pressure balancing membrane is attached to the connecting hole 4 to connect with the external air pressure and prevent liquid from entering the sealed cavity 3.

[0056] In some embodiments of this application, the diameter of the connecting hole 4 is greater than 1 mm, and its size design can be tailored to the specific size of the mobile terminal to ensure that it can balance the air pressure inside and outside the device body 1.

[0057] Please see Figure 5 In some embodiments of this application, a control method for a mobile terminal is also proposed, comprising the following steps: Step S1: Obtain the status data detected by the detection device; Step S2: If the mobile terminal is determined to be in an abnormal state based on the status data, control the switch device 2 to switch from the open state to the closed state.

[0058] In this step, by detecting the status data of the mobile terminal, when it is determined that the mobile terminal is in an abnormal state, the control device can control the switch device 2 to close the connecting hole 4, so that the internal sealing cavity 3 of the main body of the device 1 is transformed into a sealed state. This action causes the gas in the sealing cavity 3 to be compressed and generate a significantly increased pressure at the moment when the mobile terminal is impacted and deformed, thereby forming a reverse thrust to offset the external impact force, which can effectively absorb and dissipate the impact energy.

[0059] Abnormal states of mobile terminals include, but are not limited to, states such as being dropped, submerged, or bumped.

[0060] When the mobile terminal is determined to be in an abnormal state such as being dropped, submerged, or bumped, the switch device 2 is immediately controlled to close the connecting hole 4, so that the internal sealing cavity 3 quickly becomes sealed. In the case of a drop or bump, the mobile terminal can compress the gas in the sealing cavity 3 when it deforms, generating a reverse thrust to offset the impact; in the case of submersion, it can immediately block the channels through which liquid may seep in, improving emergency waterproofing capabilities.

[0061] In some embodiments of this application, the abnormal state includes a fall state; Step S2: If the mobile terminal is determined to be in an abnormal state based on the status data, control the switch device 2 to switch from the open state to the closed state, including: Step S21: When the mobile terminal is in the drop state, control the switch device 2 to switch from the open state to the closed state.

[0062] In this step, when the status data determines that the mobile terminal is in a drop state, the control device controls the switch device 2 to switch from the open state to the closed state, thereby instantly isolating the sealed cavity 3 inside the main body of the device 1 from the external environment, so as to prepare for the deformation of the sealed cavity 3 to compress the cavity gas, thereby generating a reverse thrust to buffer the impact force that the mobile terminal will receive.

[0063] In some embodiments of this application, the state data includes acceleration values ​​and / or acceleration duration; Step S21: Before controlling the switch device 2 to switch from the open state to the closed state when the mobile terminal is in the drop state, the following steps are also included: Step S20: If the acceleration value and / or acceleration duration exceed the corresponding preset value, determine that the mobile terminal is in the fall state.

[0064] In this step, by setting preset values ​​for acceleration and acceleration duration, the system can accurately and reliably identify whether the mobile terminal is in a fall state. When the acceleration value and / or acceleration duration detected by the detection device during normal shaking or non-destructive impact caused by the user in daily use do not exceed the corresponding preset values, the control device will not activate the switch device 2. Only when abnormal motion consistent with a high-speed fall is detected and the acceleration value and / or acceleration duration exceeds the corresponding preset values ​​is a fall state determined. This ensures timely response from the switch device 2 while avoiding unnecessary opening and closing of the switch device 2 and energy consumption due to misjudgment, thus improving the accuracy and stability of the system's judgment.

[0065] In some embodiments of this application, the mobile terminal further includes a pressurizing device for pressurizing the sealed cavity 3 when the switching device 2 is in the closed state, and the status data also includes the displacement data of the mobile terminal; Step S21: After controlling the switch device 2 to switch from the open state to the closed state when the mobile terminal is in the drop state, the method further includes: Step S22: Obtain the displacement data detected by the detection device.

[0066] In this step, the detection device collects and outputs precise displacement data of the mobile terminal during the fall in real time.

[0067] Step S23: Control the pressurization device to work based on the displacement data.

[0068] In this step, the control device calculates the drop height and expected impact intensity of the mobile terminal based on the displacement data, and dynamically adjusts the working parameters of the pressurization device according to the calculated expected impact intensity of the mobile terminal, injecting a corresponding volume of gas into the sealing cavity 3, thereby increasing the gas pressure in the sealing cavity 3 before the collision, so that the sealing cavity 3 generates a reverse thrust that is more matched with the impact force when deformed, thereby dynamically optimizing the buffering effect and realizing the adaptive adjustment of the pressure in the sealing cavity 3 before the mobile terminal is subjected to different degrees of drop impact.

[0069] In some embodiments of this application, step S2: after controlling the switch device 2 to switch from the open state to the closed state when the mobile terminal is determined to be in an abnormal state by the state data, it further includes: Step S3: If the mobile terminal is determined to be in a normal state based on the status data, control the switch device 2 to switch from the closed state to the open state.

[0070] In this step, when the mobile terminal is detected to have recovered from an abnormal state to a normal operating state, the control device controls the switch device 2 to switch from the closed state back to the open state, so that the sealed cavity 3 is connected to the external environment again, thereby ensuring the internal and external air pressure balance of the main body 1 of the mobile terminal under normal conditions.
