Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a wearable device. Background Art

[0002] In wearable devices such as watches and bracelets, it is necessary to open air holes on the shell of the wearable device to achieve connectivity between the internal and external environments of the device, but the provision of air holes can easily reduce the waterproof performance of the wearable device. In order to prevent liquid water or water vapor from entering the wearable device through the air holes, a balancing valve assembly is provided on the outside of the shell, and the balancing valve assembly covers the air holes. The balancing valve assembly can prevent water from passing through but allow air to pass through, thereby connecting the inside of the wearable device with the external environment, and playing a role in waterproofing and balancing the air pressure inside and outside the wearable device. However, since the balancing valve assembly is provided on the outside of the shell and is visible from the outside, it can easily lead to risks in the waterproof reliability of the wearable device, which in turn leads to waterproof failure. Utility Model Content

[0003] The embodiments of the present application provide a wearable device, which can improve the waterproof reliability of the wearable device and avoid the problem of waterproof reliability failure of the device.

[0004] In a first aspect, the present application provides a wearable device, the wearable device comprising:

[0005] A shell, the shell comprising an outer shell and an inner shell, the outer shell being sleeved on the periphery of the inner shell, the outer shell having an air vent, the air vent penetrating the outer shell and connecting the inside of the shell with the outside of the shell, the inner shell having a pressure relief channel and a connecting surface, the pressure relief channel having a first opening and a second opening, the first opening being connected to the air vent, and the second opening being located on the connecting surface; and

[0006] A balancing valve assembly is located in the shell, the balancing valve assembly includes a first adhesive layer, a second adhesive layer, a waterproof breathable membrane and a clamping bracket, the first adhesive layer is connected to the connecting surface, the waterproof breathable membrane is connected to the surface of the first adhesive layer facing away from the connecting surface, the projection of the waterproof breathable membrane along the thickness direction of the balancing valve assembly covers the second opening, the second adhesive layer is connected to the surface of the waterproof breathable membrane facing away from the first adhesive layer, the clamping bracket is located on the surface of the second adhesive layer facing away from the waterproof breathable membrane, the clamping bracket is fixedly connected to the inner shell, the clamping bracket has a plurality of spaced perforations, each of the perforations penetrates the clamping bracket along the thickness direction of the clamping bracket, and the projection of at least some of the plurality of perforations along the thickness direction of the balancing valve assembly is located within the second opening.

[0007] It is understandable that the use of a closed shell can form a closed space inside the wearable device, thereby achieving a good waterproof effect. However, as the temperature inside and outside the shell changes, an air pressure difference is easily formed between the inside and outside of the shell, resulting in gaps or cracks in the shell under the long-term effect of the air pressure difference, affecting the waterproof and protective performance of the shell. Therefore, in the related art, in order to balance the air pressure inside and outside the shell and ensure the waterproof effect of the shell, air holes are set on the shell, and a balancing valve assembly is set on the outside of the shell to cover the air holes, so as to take into account both air permeability and waterproofness. However, since the balancing valve assembly is set on the outside of the shell and is visible from the outside, it is easy to cause risks to the waterproof reliability of the wearable device, which in turn leads to waterproof failure.

[0008] Based on this, in the embodiment of the present application, a balancing valve assembly is arranged inside the shell, and a pressure relief channel connected between the air vent and the balancing valve assembly is arranged on the shell. On the one hand, the pressure relief channel of the shell can provide a path and guide for the gas passing through the air vent of the shell, so as to guide the gas outside the device to the balancing valve assembly inside the device. Because the balancing valve assembly can prevent water molecules from entering and allow gas molecules to enter and exit freely, the balancing valve assembly can achieve the functions of waterproofing and balancing the air pressure inside and outside the shell. On the other hand, since the balancing valve assembly is arranged inside the shell, the balancing valve assembly is invisible in appearance and is not easily damaged by external forces. It can improve the waterproof reliability of the wearable device and avoid the problem of failure of the waterproof reliability of the device.

[0009] In addition, since the waterproof breathable membrane has a low structural strength and is fixed to the inner shell by bonding, if no additional reinforcement structure is provided in the balancing valve assembly to enhance the structural strength of the waterproof breathable membrane, when the wearable device is in water, water will enter the wearable device through the vents and the pressure relief channel, causing the waterproof breathable membrane inside the wearable device to be subjected to a large pressure, which may easily cause the waterproof breathable membrane to deform due to pressure. When the deformation is particularly large, the waterproof breathable membrane may produce micro cracks or even macro cracks. For example, excessive water pressure may cause the waterproof breathable membrane to rupture, the waterproof breathable membrane may fall off the vents, etc., and the water flow outside the wearable device may enter the device through the failed waterproof breathable membrane, causing damage to the electronic components and / or mechanical structure inside the device.

[0010] Therefore, a compression bracket is provided to provide certain support performance and protection for the waterproof breathable membrane, so that the waterproof breathable membrane can be supported by the compression bracket after being deformed to a certain extent, effectively preventing the waterproof breathable membrane from failing due to excessive deformation, and ensuring the working reliability of the waterproof breathable membrane.

[0011] Because the clamping bracket is also fixedly connected to the inner shell, the other structural parts in the balancing valve assembly can be clamped and limited on the inner shell. On the one hand, the clamping bracket has a simple structure, is easy to manufacture, occupies a small space, has a great advantage in cost, and can meet the development needs of miniaturization and thinning of wearable devices. On the other hand, by clamping the bracket to form a reliable fixation between the other structural parts in the balancing valve assembly and the inner shell, it can avoid the problem of failure of the balancing valve assembly due to sliding or movement of other structural parts in the balancing valve assembly, and the reliability is better.

[0012] In addition, since the clamping bracket can achieve breathable support and fixed clamping functions through the structural design of only one part, compared with the two parts required for separate setting of breathable support and fixed clamping, the cost of one part is saved, which is beneficial to reducing the overall cost of the balancing valve assembly.

[0013] In a possible implementation, a thickness direction of the balancing valve assembly is arranged parallel to a thickness direction of the wearable device.

[0014] Under this setting, the stacking direction of each structure in the balancing valve assembly located in the receiving groove is parallel to the thickness direction of the wearable device. The balancing valve assembly will mainly occupy the space in the length direction of the wearable device and occupy less space in the thickness direction of the wearable device. Therefore, the space reduced by the balancing valve assembly in the thickness direction of the wearable device can be ceded to reduce the thickness of the entire device, which is conducive to adapting to the development trend of thinning wearable devices.

[0015] In a possible implementation, a thickness direction of the balancing valve assembly is arranged perpendicular to a thickness direction of the wearable device.

[0016] Under this setting, the stacking direction of each structure in the balancing valve assembly located in the receiving groove is arranged parallel to the length direction of the wearable device, and the balancing valve assembly will mainly occupy the space in the thickness direction of the wearable device and occupy less space in the length direction of the wearable device. Therefore, the space reduced by the balancing valve assembly in the length direction of the wearable device can be ceded to provide a larger installation space for the battery.

[0017] In a possible implementation manner, the pressure relief channel includes a first channel and a second channel, one end of the first channel has the first opening, the first channel is connected to the air vent, the other end of the first channel is connected to the second channel, and the second channel has the second opening at one end away from the first channel;

[0018] An extension direction of the first channel is perpendicular to a thickness direction of the wearable device, and an extension direction of the second channel is parallel to the thickness direction of the wearable device.

[0019] It is understandable that, since the first channel extends in a direction perpendicular to the thickness of the wearable device, and the second channel extends in a direction parallel to the thickness of the wearable device, the pressure relief channel formed by the first channel and the second channel can present an L shape as a whole. By designing the structural form of the pressure relief channel in a targeted manner, the extension direction of the pressure relief channel can be fully adapted to the structural setting of the balancing valve assembly stacked in the thickness direction of the wearable device without changing the structure of the balancing valve assembly stacked in the thickness direction of the wearable device. Not only can the gas at the air vent of the shell be conveniently and quickly guided to the balancing valve assembly, so that the balancing valve assembly plays a role in waterproofing and breathability and balancing the air pressure inside and outside the wearable device, but the extension direction of the pressure relief channel can also have strong adaptability and flexibility.

[0020] In a possible implementation manner, at least one of the first adhesive layer and the second adhesive layer is a foam adhesive layer.

[0021] In this configuration, at least one of the first adhesive layer and the second adhesive layer is an elastic adhesive layer with good elasticity, which can be compressed and deformed elastically after being pressed, and rebound after the pressure is removed. By utilizing the good elasticity of the foam adhesive layer, the height of the foam adhesive layer can be fully adapted to the height of the gap between the second adhesive layer and the fixed bracket, so as to eliminate the gap between the fixed bracket and the waterproof breathable membrane, which not only facilitates the fixed bracket to better press the waterproof breathable membrane onto the inner shell, but also plays the role of interference compression and waterproofing.

[0022] In a possible implementation manner, the first adhesive layer has a first through hole, the first through hole penetrates the first adhesive layer along a thickness direction of the first adhesive layer and is connected to the second opening;

[0023] The waterproof and breathable membrane covers the first through hole;

[0024] The second adhesive layer has a second through hole, the second through hole penetrates the second adhesive layer along the thickness direction of the second adhesive layer, and the second through hole and the second opening are arranged opposite to each other in the thickness direction of the balancing valve assembly;

[0025] At least some of the plurality of through holes are arranged opposite to the second opening in the thickness direction of the balancing valve assembly and are communicated with the second through hole.

[0026] It can be understood that in the balancing valve assembly, since each layer of the structure is provided with a hole for ventilation at the position corresponding to the second opening of the pressure relief channel, when in use, it can block water and allow the gas to smoothly pass through the waterproof breathable membrane and through the balancing valve assembly into the wearable device, thereby balancing the internal and external air pressures of the wearable device.

[0027] In a possible implementation manner, the inner shell has a receiving groove, a bottom wall of the receiving groove is the connecting surface, and the first adhesive layer, the waterproof breathable membrane and the second adhesive layer are all located in the receiving groove;

[0028] The clamping bracket includes a main body, a first connecting arm and a second connecting arm, the main body covers the opening of the accommodating groove and limits the first adhesive layer, the waterproof breathable membrane and the second adhesive layer in the accommodating groove, the first connecting arm is connected to one end of the main body and is clamped to the inner shell or locked by screws, and the second connecting arm is connected to the other end of the main body and is clamped to the inner shell or locked by screws.

[0029] Under this setting, the clamping bracket can be detachably connected to the inner shell as a whole, which is convenient for quickly assembling the clamping bracket to the inner shell and removing it from the inner shell, which is beneficial to improving the installation efficiency and installation reliability between the balancing valve assembly and the inner shell.

[0030] In a possible implementation manner, the housing includes two first side walls, the two first side walls extend along a width direction of the wearable device and are arranged opposite to each other in a length direction of the wearable device, and the opening of the air vent is located on one of the two first side walls;

[0031] The wearable device includes two wristbands, which are respectively connected to the two first side walls, and one of the wristbands arranged on the same side as the ventilation hole covers the ventilation hole.

[0032] It is understandable that after the wristband is connected to the shell, the wristband can cover the air holes, and the gap between the wristband and the shell can keep the air holes connected to the outside world, so as to facilitate the balance of air pressure inside and outside the wearable device. On the one hand, using a wristband to cover the air holes can avoid the air holes from having an adverse effect on the appearance consistency of the wearable device due to their visible appearance, which is conducive to making the wearable device more beautiful. On the other hand, using a wristband to cover the air holes can also prevent sharp objects from being inserted into the air holes, causing the balance valve assembly to fail, thereby ensuring the working reliability of the balance valve assembly.

[0033] In a possible implementation, the wearable device further includes a battery and a motor module, the inner shell encloses an installation space, the battery is located in the installation space, the motor module is fixed to the inner shell, and is located on the same side of the battery as the balancing valve assembly.

[0034] In a possible implementation, the wearable device further includes a battery, a button module and a speaker module. The inner shell encloses an installation space, the battery is located in the installation space, the button module passes through the inner shell and the outer shell, and the speaker module is fixed to the inner shell and is located on the same side of the battery as the button module.

[0035] In a second aspect, the present application further provides a wearable device, the wearable device comprising:

[0036] A shell, the shell comprising an outer shell and an inner shell, the outer shell being sleeved on the periphery of the inner shell, the outer shell having an air vent, the air vent penetrating the outer shell and connecting the inside of the shell with the outside of the shell, the inner shell having a pressure relief channel and a connecting surface, the pressure relief channel having a first opening and a second opening, the first opening being connected to the air vent, and the second opening being located on the connecting surface; and

[0037] A balancing valve assembly is located in the shell, the balancing valve assembly is connected to the connecting surface, the thickness direction of the balancing valve assembly is parallel to the thickness direction of the wearable device, the balancing valve assembly includes a waterproof and breathable membrane, and the projection of the waterproof and breathable membrane along the thickness direction of the balancing valve assembly covers the second opening.

[0038] It is understandable that the use of a closed shell can form a closed space inside the wearable device, thereby achieving a good waterproof effect. However, as the temperature inside and outside the shell changes, an air pressure difference is easily formed between the inside and outside of the shell, resulting in gaps or cracks in the shell under the long-term effect of the air pressure difference, affecting the waterproof and protective performance of the shell. Therefore, in the related art, in order to balance the air pressure inside and outside the shell and ensure the waterproof effect of the shell, air holes are set on the shell, and a balancing valve assembly is set on the outside of the shell to cover the air holes, so as to take into account both air permeability and waterproofness. However, since the balancing valve assembly is set on the outside of the shell and is visible from the outside, it is easy to cause risks to the waterproof reliability of the wearable device, which in turn leads to waterproof failure.

[0039] Based on this, in the embodiment of the present application, a balancing valve assembly is arranged inside the shell, and a pressure relief channel connected between the air vent and the balancing valve assembly is arranged on the shell. On the one hand, the pressure relief channel of the shell can provide a path and guide for the gas passing through the air vent of the shell, so as to guide the gas outside the device to the balancing valve assembly inside the device. Because the balancing valve assembly can prevent water molecules from entering and allow gas molecules to enter and exit freely, the balancing valve assembly can achieve the functions of waterproofing and balancing the air pressure inside and outside the shell. On the other hand, since the balancing valve assembly is arranged inside the shell, the balancing valve assembly is invisible in appearance and is not easily damaged by external forces. It can improve the waterproof reliability of the wearable device and avoid the problem of failure of the waterproof reliability of the device.

[0040] In addition, the stacking direction of each structure in the balancing valve assembly located in the receiving groove is arranged parallel to the thickness direction of the wearable device. The balancing valve assembly will mainly occupy the space in the length direction of the wearable device and occupy less space in the thickness direction of the wearable device. Therefore, the space reduced by the balancing valve assembly in the thickness direction of the wearable device can be ceded to reduce the thickness of the whole device, which is conducive to adapting to the development trend of thinning wearable devices.

[0041] In a possible implementation manner, the pressure relief channel includes a first channel and a second channel, one end of the first channel has the first opening, the first channel is connected to the air vent, the other end of the first channel is connected to the second channel, and the second channel has the second opening at one end away from the first channel;

[0042] An extension direction of the first channel is perpendicular to a thickness direction of the wearable device, and an extension direction of the second channel is parallel to the thickness direction of the wearable device.

[0043] It is understandable that, since the first channel extends in a direction perpendicular to the thickness of the wearable device, and the second channel extends in a direction parallel to the thickness of the wearable device, the pressure relief channel formed by the first channel and the second channel can present an L shape as a whole.

[0044] In a possible implementation manner, the balancing valve assembly further includes a first adhesive layer, a second adhesive layer, a third adhesive layer, a support member, a reinforcement member, a buffer member, and a fixing bracket;

[0045] The first adhesive layer is connected to the connecting surface, the waterproof breathable membrane is connected to the surface of the first adhesive layer facing away from the connecting surface, the supporting member is connected to the surface of the waterproof breathable membrane facing away from the first adhesive layer, the second adhesive layer is connected to the surface of the supporting member facing away from the waterproof breathable membrane, the reinforcing member is connected to the surface of the second adhesive layer facing away from the supporting member, the third adhesive layer is connected to the surface of the reinforcing member facing away from the second adhesive layer, the buffer member is connected to the surface of the third adhesive layer facing away from the reinforcing member, the fixing bracket is located on the surface of the buffer member facing away from the third adhesive layer, and the fixing bracket is fixedly connected to the inner shell.

[0046] It can be understood that in this embodiment, the waterproof breathable membrane can cover the second opening of the pressure relief channel, so that the gas in the pressure relief channel can be guided to the waterproof breathable membrane. The microstructure of the waterproof breathable membrane makes it waterproof and breathable, which can facilitate the passage of gas. In addition, since this embodiment also sequentially arranges a reinforcing member, a buffer member and a fixed bracket on the side of the waterproof breathable membrane away from the second opening of the pressure relief channel, the reinforcing member can support the waterproof breathable membrane, the buffer member can eliminate the gap between the waterproof breathable membrane and the fixed bracket, and the fixed bracket can press the buffer member to fasten the balancing valve assembly to the inner shell. By continuously stacking the various structures in the balancing valve assembly, the balancing valve assembly and the inner shell can have good contact performance on the basis of ensuring the waterproof and breathable performance of the balancing valve assembly.

[0047] In a possible implementation manner, the first adhesive layer has a first through hole, the first through hole penetrates the first adhesive layer along a thickness direction of the first adhesive layer and is connected to the second opening;

[0048] The waterproof and breathable membrane covers the first through hole;

[0049] The support member has a first through hole, the first through hole penetrates the support member along the thickness direction of the support member, and the first through hole and the second opening are arranged opposite to each other along the thickness direction of the balancing valve assembly;

[0050] The second adhesive layer has a second through hole, the second through hole penetrates the second adhesive layer along the thickness direction of the second adhesive layer and is connected with the first via hole;

[0051] The reinforcement member has a plurality of second via holes arranged at intervals, each of the second via holes penetrates the reinforcement member along the thickness direction of the reinforcement member, and at least some of the plurality of second via holes are connected to the second through hole;

[0052] The third adhesive layer has a third through hole, the third through hole penetrates the third adhesive layer along a thickness direction of the third adhesive layer, and the third through hole is connected to at least part of the second via holes among the plurality of second via holes;

[0053] The buffer member has a third via hole, the third via hole penetrates the buffer member along the thickness direction of the buffer member, and the third via hole is connected to the third through hole;

[0054] The fixing bracket has a fourth through hole, the fourth through hole penetrates the fixing bracket along a thickness direction of the fixing bracket, and the fourth through hole is communicated with the third through hole.

[0055] It can be understood that in the balancing valve assembly, since each layer of the structure is provided with a hole for ventilation at the position corresponding to the second opening of the pressure relief channel, when in use, it can block water and allow the gas to smoothly pass through the waterproof breathable membrane and through the balancing valve assembly into the wearable device, thereby balancing the internal and external air pressures of the wearable device.

[0056] In a possible embodiment, the balancing valve assembly further includes a first adhesive layer, a second adhesive layer and a compression bracket, the first adhesive layer is connected to the connecting surface, the waterproof breathable membrane is connected to the surface of the first adhesive layer facing away from the connecting surface, the projection of the waterproof breathable membrane along the thickness direction of the balancing valve assembly covers the second opening, the second adhesive layer is connected to the surface of the waterproof breathable membrane facing away from the first adhesive layer, the compression bracket is located on the surface of the second adhesive layer facing away from the waterproof breathable membrane, the compression bracket is fixedly connected to the inner shell, the compression bracket has a plurality of spaced-apart perforations, each of the perforations penetrates the compression bracket along the thickness direction of the compression bracket, and the projection of at least some of the plurality of perforations along the thickness direction of the balancing valve assembly is located within the second opening.

[0057] It is understandable that, due to the low structural strength of the waterproof breathable membrane, and the waterproof breathable membrane is fixed to the inner shell by bonding. If no additional reinforcement structure is provided in the balancing valve assembly to enhance the structural strength of the waterproof breathable membrane, when the wearable device is in the water, water will enter the wearable device through the vents and the pressure relief channel, causing the waterproof breathable membrane inside the wearable device to be subjected to a large pressure, which may easily cause the waterproof breathable membrane to deform due to pressure. When the deformation is particularly large, the waterproof breathable membrane may produce micro cracks or even macro cracks. For example, excessive water pressure may cause the waterproof breathable membrane to rupture, the waterproof breathable membrane may fall off the vents, etc., and the water flow outside the wearable device may enter the device through the failed waterproof breathable membrane, causing damage to the electronic components and / or mechanical structure inside the device.

[0058] Therefore, a compression bracket is provided to provide certain support performance and protection for the waterproof breathable membrane, so that the waterproof breathable membrane can be supported by the compression bracket after being deformed to a certain extent, effectively preventing the waterproof breathable membrane from failing due to excessive deformation, thereby ensuring the working reliability of the waterproof breathable membrane.

The air vent of the housing 10 may connect the interior of the housing 10 and the exterior of the housing 10, so that air can flow between the interior and exterior of the wearable device 100. The pressure relief channel 12 of the housing 10 is connected to the air vent of the housing 10, and can provide a path and guide for the air flow inside the device. The balancing valve assembly 40 is located in the housing 10 and is connected to the other end of the pressure relief channel 12 of the housing 10 away from the air vent, so as to achieve communication with the outside of the device through the pressure relief channel 12. The balancing valve assembly 40 can prevent water from passing through but allow air to pass through, so that the interior of the wearable device 100 can be connected to the external environment, and it can also play a role in waterproofing and balancing the air pressure inside and outside the wearable device 100. The display screen 30 is connected to one side of the housing 10 in the Z direction. The display screen 30 can be used to display text, images, videos, etc. The user can perform finger recognition interaction through the interactive sensor under the display screen 30. Two wristbands 20 are respectively connected to the two sides of the housing 10 in the X direction. The two wristbands 20 can form the appearance structure of the wearable device 100 together with the display screen 30 and the housing 10. The two wristbands 20 can be buckled with each other and can be loosened or tightened according to the circumference of the user's wrist to wear the wearable device 100 on the user's wrist.

[0100] The display screen 30 can receive input operations from the user, and make corresponding outputs in response to the input operations. For example, the user can manipulate the icons of the UI (User Interface) interface on the display screen 30 by touching, pressing, clicking, and sliding to indicate preview, opening, editing, moving, and deleting the content. The display screen 30 can be, but is not limited to, a liquid crystal display (LCD) display screen, an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode display screen, a micro organic light-emitting diode display screen, a micro organic light-emitting diode display screen, and a quantum dot light emitting diode (QLED) display screen.

[0101] The following description will be made by taking the case where the number of air holes is one and the type of air holes is only a balancing hole for balancing the internal and external air pressure as an example. However, in other embodiments, the air holes may also be microphone holes or speaker holes for balancing the internal and external air pressures and transmitting sound. The structural improvements involved in the wearable device described below can be used in microphone holes or speaker holes for balancing the internal and external air pressures and transmitting sound without any conflict, and there is no strict limitation on this.

[0102] Exemplarily, the housing 10 may include two first side walls 101, the two first side walls 101 extend along the Y direction and are arranged opposite to each other in the X direction, and the opening of the air vent is located on one of the two first side walls 101. Two wristbands 20 are respectively connected to the two first side walls 101, and one wristband 20 arranged on the same side of the air vent covers the air vent.

[0103] It is understandable that after the wristband 20 is connected to the housing 10, the wristband 20 can cover the air holes, and the gap between the wristband 20 and the housing 10 can keep the air holes connected to the outside world, so as to facilitate the balance of air pressure inside and outside the wearable device 100. On the one hand, using the wristband 20 to cover the air holes can avoid the air holes from having an adverse effect on the appearance consistency of the wearable device 100 due to their visible appearance, which is conducive to making the wearable device 100 more beautiful. On the other hand, using the wristband 20 to cover the air holes can also prevent sharp objects from being inserted into the air holes, causing the balance valve assembly 40 to fail, thereby ensuring the working reliability of the balance valve assembly 40.

[0104] It should be noted that Figure 2 The connection relationship between the housing 10, the two wristbands 20, the display screen 30 and the balancing valve assembly 40 is only schematically described, and the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the wearable device 100. In other embodiments of the present application, the wearable device 100 may include more or fewer components than shown in the figure, or combine some components, or split some components, or arrange the components differently.

[0105] It is understandable that the use of a closed shell can form a closed space inside the wearable device, thereby achieving a good waterproof effect. However, as the temperature inside and outside the shell changes, an air pressure difference is easily formed between the inside and outside of the shell, resulting in gaps or cracks in the shell under the long-term effect of the air pressure difference, affecting the waterproof and protective performance of the shell. Therefore, in the related art, in order to balance the air pressure inside and outside the shell and ensure the waterproof effect of the shell, air holes are set on the shell, and a balancing valve assembly is set on the outside of the shell to cover the air holes, so as to take into account both air permeability and waterproofness. However, since the balancing valve assembly is set on the outside of the shell and is visible from the outside, it is easy to cause risks to the waterproof reliability of the wearable device, which in turn leads to waterproof failure.

[0106] Based on this, in the embodiment of the present application, the balancing valve assembly 40 is arranged inside the shell 10, and a pressure relief channel 12 connected between the air vent and the balancing valve assembly 40 is arranged on the shell 10. On the one hand, the pressure relief channel 12 of the shell 10 can provide a path and guide for the gas passing through the air vent of the shell 10, so as to guide the gas outside the device to the balancing valve assembly 40 inside the device. Because the balancing valve assembly 40 can prevent water molecules from entering and allow gas molecules to enter and exit freely, the balancing valve assembly 40 can achieve the functions of waterproofing and balancing the air pressure inside and outside the shell 10. On the other hand, since the balancing valve assembly 40 is arranged inside the shell 10, the balancing valve assembly 40 is invisible in appearance and is not easily damaged by external forces. It can improve the waterproof reliability of the wearable device 100 and avoid the problem of failure of the waterproof reliability of the device.

[0107] The following will describe in detail the balancing valve assembly 40 and the specific application of the balancing valve assembly 40 provided in the present application through two specific embodiments.

[0108] First embodiment:

[0109] Please refer to Figure 3a and Figure 3b , Figure 3a yes Figure 2 The structural schematic diagram of the housing 10 of the wearable device 100 is shown in FIG. Figure 3b yes Figure 3a An exploded schematic diagram of the housing 10 is shown.

[0110] The housing 10 may include a middle frame 13 and a bottom shell 14. The display screen 30 and the bottom shell 14 are respectively connected to opposite sides of the middle frame 13, and the display screen 30 and the bottom shell 14 are arranged opposite to each other in the Z direction. The display screen 30, the middle frame 13 and the bottom shell 14 can enclose a cavity of the wearable device 100, and the cavity of the wearable device 100 can accommodate components such as a main board, a battery 50, and a balancing valve assembly 40.

[0111] Exemplarily, the middle frame 13 and the bottom shell 14 may be an integrated structure, such as an integrated structure formed by an integrated molding method. Alternatively, the middle frame 13 and the bottom shell 14 may also be an assembled structure. The material of the middle frame 13 may be metal, and the material of the bottom shell 14 may be a non-metallic material, such as plastic. Alternatively, the material of the middle frame 13 may be metal, and the material of the bottom shell 14 may also be metal.

[0112] Please refer to Figure 4a , Figure 4b and Figure 5 , Figure 4a yes Figure 3a A schematic structural diagram of the middle frame 13 of the housing 10 is shown. Figure 4b yes Figure 4a The exploded schematic diagram of the middle frame 13 is shown in FIG. Figure 5 is along Figure 3a The middle frame 13 may include an outer shell 15 and an inner shell 16. The outer shell 15 is sleeved around the outer periphery of the inner shell 16, the outer shell 15 is an appearance structure in the middle frame 13, and the inner shell 16 is an appearance invisible structure in the middle frame 13.

[0113] Specifically, the outer shell 15 may be annular and enclose a receiving space W, which may be used to provide installation space for components such as the inner shell 16 and the battery 50. The outer shell 15 also has a vent 11, which is the vent of the housing 10 described above. The vent 11 passes through the outer shell 15 and communicates with the receiving space W of the outer shell 15. The vent 11 also communicates the inside of the housing 10 with the outside of the housing 10.

[0114] In a possible implementation, please refer to Figure 4a and Figure 4c , Figure 4c yes Figure 3a Another structural schematic diagram of the middle frame 13 of the housing 10 is shown. The wearable device may further include a dustproof net 90, which is connected to the surface of the outer shell 15 facing away from the inner shell 16 (i.e., the outer surface of the housing 10), and the dustproof net 90 covers the air vent 11. It can be understood that by arranging the dustproof net 90 outside the air vent 11, it is helpful to prevent dust outside the wearable device 100 from entering the air vent 11, thereby improving the dustproof performance of the wearable device 100.

[0115] Please continue reading Figure 4a , Figure 4b and Figure 5 In this embodiment, the inner shell 16 is located in the receiving space W of the outer shell 15, and the inner shell 16 is annular and connected to the outer shell 15. The inner shell 16 has a receiving groove 17 and a pressure relief channel 12. Among them, the receiving groove 17 of the inner shell 16 is used to accommodate the balancing valve assembly 40. By providing the receiving groove 17, the balancing valve assembly 40 can be accommodated in the receiving groove 17, and the movement of the balancing valve assembly 40 along the X, Y, and Z directions is limited by the spatial layout of the receiving groove 17, further improving the installation stability and reliability of the balancing valve assembly 40. The pressure relief channel 12 of the inner shell 16 is the pressure relief channel 12 of the shell 10 mentioned above.

[0116] The bottom surface of the receiving groove 17 of the inner shell 16 forms a connecting surface 161 of the inner shell 16, and the connecting surface 161 of the inner shell 16 can extend in the Z direction or the X direction, and is used to connect with the balancing valve assembly 40. When the connecting surface 161 of the inner shell 16 extends in the Z direction, the thickness direction of the balancing valve assembly 40 connected to the connecting surface 161 is parallel to the X direction (i.e., perpendicular to the Z direction), and the balancing valve assembly 40 component will mainly occupy the Z direction space in the wearable device 100. When the connecting surface 161 of the inner shell 16 extends in the X direction, the thickness direction of the balancing valve assembly 40 connected to the connecting surface 161 is parallel to the Z direction (i.e., perpendicular to the X direction), and the balancing valve assembly 40 component will occupy the X direction space in the wearable device 100.

[0117] Of course, in other embodiments, the inner shell 16 may not be provided with the receiving groove 17 , but the surface of the inner shell 16 directly forms the connecting surface 161 of the inner shell 16 , and there is no strict limitation to this.

[0118] The pressure relief channel 12 of the inner shell 16 is connected between the vent hole 11 of the outer shell 15 and the receiving groove 17 of the inner shell 16, and communicates the vent hole 11 of the outer shell 15 and the receiving groove 17 of the inner shell 16. The pressure relief channel 12 of the inner shell 16 has a first opening 121 and a second opening 122. The first opening 121 of the pressure relief channel 12 is arranged correspondingly to and communicates with the vent hole 11 of the outer shell 15, so that the vent hole of the outer shell 15 and the pressure relief channel 12 of the inner shell 16 can be communicated with each other. The second opening 122 of the pressure relief channel 12 is located at the connecting surface 161 of the receiving groove 17, so that the water and gas entering the wearable device 100 through the vent hole of the outer shell 15 can be guided to the balancing valve assembly 40 provided at the connecting surface 161 under the guidance of the pressure relief channel 12, and under the screening and filtering of the balancing valve assembly 40, the water is prevented from entering and the gas is allowed to enter, so as to realize the waterproofing of the balancing valve assembly 40 and the function of balancing the air pressure inside and outside the device.

[0119] In a possible implementation, please refer to Figure 6 and Figure 7 , Figure 6 is along Figure 3a A schematic cross-sectional diagram of a partial structure obtained by cutting along the cutting line AA. Figure 7 is along Figure 3a Another schematic cross-sectional view of a partial structure obtained by cutting along the cutting line AA. Figure 6 and Figure 7 In the figure, the structures of the inner shell 16 and the outer shell 15 are merely schematic diagrams for the convenience of explanation, and do not constitute specific limitations on the inner shell 16 and the outer shell 15.

[0120] The connecting surface 161 of the inner shell 16 can be arranged parallel to the Z direction. Under this arrangement, the stacking direction of each structure in the balancing valve assembly 40 located in the receiving groove 17 is arranged parallel to the X direction. The balancing valve assembly 40 will mainly occupy the space in the Z direction of the wearable device 100 and occupy less space in the X direction. As a result, the space reduced in the X direction by the balancing valve assembly 40 can be ceded to provide a larger installation space for the battery 50. In order to enable the pressure relief channel 12 of the inner shell 16 to achieve the function of connecting the air vent 11 of the outer shell 15 and the receiving groove 17 of the inner shell 16, the pressure relief channel 12 of the inner shell 16 can extend in a straight line or curve between the air vent 11 of the outer shell 15 and the receiving groove 17 of the inner shell 16.

[0121] For example, Figure 6 As shown, the pressure relief channel 12 can extend linearly along the X direction and be horizontally connected between the air vent 11 of the outer shell 15 and the receiving groove 17 of the inner shell 16. Alternatively, as Figure 7As shown, the pressure relief channel 12 may also extend in a curve and be bent to connect between the air vent 11 of the outer shell 15 and the receiving groove 17 of the inner shell 16. Alternatively, the pressure relief channel 12 may also extend in a straight line in a direction inclined to the X direction and be obliquely connected between the air vent 11 of the outer shell 15 and the receiving groove 17 of the inner shell 16. Of course, the pressure relief channel 12 may also be connected between the air vent 11 of the outer shell 15 and the receiving groove 17 of the inner shell 16 in other forms, as long as the air vent 11 of the outer shell 15 and the receiving groove 17 of the inner shell 16 can be connected, and there is no strict limitation on this.

[0122] In another possible embodiment, please refer to 5. In this embodiment, the same contents as the previous embodiment are not repeated. Unlike the previous embodiment, the connection surface 161 of the inner shell 16 can be arranged parallel to the X direction. Under this setting, the stacking direction of each structure in the balance valve assembly 40 located in the receiving groove 17 is arranged parallel to the Z direction. The balance valve assembly 40 will mainly occupy the space in the X direction of the wearable device 100 and occupy less space in the Z direction. As a result, the space reduced in the Z direction of the balance valve assembly 40 can be ceded to reduce the thickness of the whole device, which is conducive to adapting to the development trend of thinning of the wearable device 100. In order to enable the pressure relief channel 12 of the inner shell 16 to achieve the function of connecting the air vent 11 of the outer shell 15 and the receiving groove 17 of the inner shell 16, the pressure relief channel 12 of the inner shell 16 can extend in a straight line or curve between the air vent 11 of the outer shell 15 and the receiving groove 17 of the inner shell 16.

[0123] like Figure 5 As shown, the pressure relief channel 12 may include a first channel 123 and a second channel 124, and the extension direction of the first channel 123 and the extension direction of the second channel 124 intersect. Specifically, the first channel 123 extends along the X direction, and one end of the first channel 123 has the first opening 121 described above, and the first channel 123 is connected to the air vent 11 of the outer shell 15 through the first opening 121, so as to achieve the connection between the pressure relief channel 12 of the inner shell 16 and the air vent 11 of the outer shell 15. One end of the second channel 124 is connected to the other end of the first channel 123, and the other end of the second channel 124 has the second opening 122 described above, and the second channel 124 is correspondingly arranged with the balancing valve assembly 40 arranged on the connecting surface 161 through the second opening 122, so as to guide the gas in the pressure relief channel 12 to the balancing valve assembly 40.

[0124] It is understandable that, since the first channel 123 extends along the X direction and the second channel 124 extends along the Z direction, the pressure relief channel 12 formed by the first channel 123 and the second channel 124 can present an L shape as a whole. By designing the structural form of the pressure relief channel 12 in a targeted manner, the extension direction of the pressure relief channel 12 can be fully adapted to the structural setting of the Z-direction stacking of the balancing valve assembly 40 without changing the Z-direction stacking structure of the balancing valve assembly 40, which can not only conveniently and quickly guide the gas at the vent hole 11 of the housing 15 to the balancing valve assembly 40, so that the balancing valve assembly 40 can play the role of waterproof and breathable and balance the air pressure inside and outside the wearable device 100, but also make the extension direction of the pressure relief channel 12 have strong adaptability and flexibility.

[0125] Of course, in other embodiments, the pressure relief channel 12 can also be connected between the air vent 11 of the outer shell 15 and the receiving groove 17 of the inner shell 16 in other forms such as oblique lines, broken lines, curves, etc. It only needs to be able to connect the air vent 11 of the outer shell 15 and the receiving groove 17 of the inner shell 16, and there is no strict limitation on this.

[0126] Please refer to Figure 8 , Fig. 9 and Fig.10 , Figure 8 1 is a schematic diagram of the assembly structure of the balancing valve assembly 40 and the housing 10 provided in the first embodiment of the present application. Fig. 9 yes Figure 8 The exploded structural diagram of the balancing valve assembly 40 is shown in FIG. Fig.10 is along Figure 1 The cross-sectional schematic diagram of a partial structure obtained by cutting along the cutting line BB shown.

[0127] The balancing valve assembly 40 is connected to the inner shell 16, and at least part of the balancing valve assembly 40 is located in the receiving groove 17 of the inner shell 16. The balancing valve assembly 40 may include a first adhesive layer 41, a second adhesive layer 42, a third adhesive layer 44, a support member 43, a waterproof breathable membrane 45, a reinforcement member 46, a buffer member 47 and a fixed bracket 48. The first adhesive layer 41, the waterproof breathable membrane 45, the support member 43, the second adhesive layer 42, the reinforcement member 46, the third adhesive layer 44, the buffer member 47 and the fixed bracket 48 can be stacked in sequence along the X direction or the Z direction. In other words, in this embodiment, the stacking direction of each structure in the balancing valve assembly 40 is stacked along the X direction or along the Z direction. The following will be described by taking the stacking arrangement of each structure in the balancing valve assembly 40 along the Z direction as an example, but it should be understood that it is not limited to this.

[0128] Specifically, the first adhesive layer 41 is located in the receiving groove 17 of the inner shell 16, and the first adhesive layer 41 is connected to the connecting surface 161 of the receiving groove 17. The first adhesive layer 41 has a first through hole 411, and the first through hole 411 of the first adhesive layer 41 penetrates the first adhesive layer 41 along the thickness direction of the first adhesive layer 41. The first through hole 411 of the first adhesive layer 41 can be arranged relative to the second opening 122 of the pressure relief channel 12 in the Z direction, and connected to each other. Therefore, by setting the first through hole 411, the gas in the pressure relief channel 12 can pass through on the basis of the bonding performance that can be achieved by the first adhesive layer 41, so that the first adhesive layer 41 has the dual functions of both adhesion and gas circulation.

[0129] Exemplarily, the material of the first adhesive layer 41 may be adhesive. The projection of the first through hole 411 of the first adhesive layer 41 along the Z direction at least partially falls into the second opening 122 of the pressure relief channel 12. The number of the first through hole 411 may be one, and it is located in the central area of ​​the first adhesive layer 41. The shape of the first through hole 411 may be rectangular. Of course, in other embodiments, the number of the first through holes 411 may also be multiple, and the multiple first through holes 411 may be arranged at intervals on the first adhesive layer 41, and at least some of the multiple first through holes 411 are connected to the second opening 122 of the pressure relief channel 12. The shape of the first through hole 411 may also be other shapes such as a circle, a polygon, etc. This embodiment does not make strict requirements on the shape, number, position and size of the first through hole 411.

[0130] The waterproof breathable membrane 45 is located in the receiving groove 17 of the inner shell 16, connected to the surface of the first adhesive layer 41 away from the connecting surface 161, and covers the first through hole 411 of the first adhesive layer 41. The waterproof breathable membrane 45 can be fixed to the inner shell 16 through the first adhesive layer 41. Among them, the waterproof breathable membrane 45 refers to a polymer waterproof material that allows air to pass through and prevents water from passing through. Exemplarily, the waterproof breathable membrane 45 can be a TPU (Thermoplastic polyurethanes, thermoplastic polyurethane elastomer rubber) expanded film, PE (polyethylene, polyethylene) film, PET (Polyethylene terephthalate, polyethylene terephthalate) film, PTFE (Polytetrafluoroethylene, polytetrafluoroethylene) expanded film, etc. Of course, the waterproof breathable membrane 45 in this embodiment is not limited to the materials listed above, as long as the physical film layer formed by the material with waterproof and breathable functions is within the scope of protection requested in this embodiment.

[0131] It is understandable that by providing the first adhesive layer 41 between the waterproof breathable membrane 45 and the inner shell 16, the first adhesive layer 41 can be used to improve the connection reliability between the waterproof breathable membrane 45 and the housing 10, and improve the waterproof performance between the waterproof breathable membrane 45 and the inner shell 16. Of course, in other embodiments, the waterproof breathable membrane 45 can also be fixed to the connection surface 161 of the inner shell 16 by other fixing members to achieve a detachable connection with the inner shell 16, which is convenient for the removal and replacement of the waterproof breathable membrane 45, and there is no strict limitation on this.

[0132] The projection of the waterproof breathable membrane 45 along the thickness direction (i.e., Z direction) of the balancing valve assembly 40 can cover the second opening 122 of the pressure relief channel 12, so that the waterproof breathable membrane 45 completely blocks the second opening 122 of the pressure relief channel 12. Under this setting, the gas flowing out through the second opening 122 of the pressure relief channel 12 can reach the waterproof breathable membrane 45 and pass through the waterproof breathable membrane 45 after passing through the first through hole 411 of the first adhesive layer 41, while the water flowing out through the second opening 122 of the pressure relief channel 12 is blocked by the waterproof breathable membrane 45 and cannot pass through.

[0133] In a possible implementation, a hydrophobic layer and / or an oleophobic layer may be provided on the surface of the waterproof breathable membrane 45. For example, a hydrophobic agent, an oleophobic agent or other materials may be coated on the surface of the waterproof breathable membrane 45 to achieve better breathability, waterproofness and dustproofness to meet different application scenarios.

[0134] In this embodiment, the support member 43 is located in the receiving groove 17 of the inner shell 16 and is connected to the surface of the waterproof breathable membrane 45 away from the first adhesive layer 41. The support member 43 can be any structural member with good reinforcement and support performance. The support member is used to provide support performance for the waterproof breathable membrane 45 and enhance the assembly reliability of the waterproof breathable membrane 45, so as to avoid the problem that the waterproof breathable membrane is prone to wrinkling and deformation due to being relatively soft and thin, which increases the difficulty of assembling the balance valve assembly 40. The support member 43 has a first through hole 431, and the first through hole 431 of the support member 43 penetrates the support member 43 along the thickness direction of the support member 43. The first through hole 431 of the support member 43 can be arranged relative to the second opening 122 of the pressure relief channel 12 in the Z direction. Therefore, by setting the first through hole 431, the gas passing through the waterproof breathable membrane 45 can pass through on the basis of the support performance that the support member 43 can achieve, so that the support member 43 has the dual functions of support and gas circulation.

[0135] Exemplarily, the material of the support member 43 may be a PET sheet. At least part of the projection of the first through hole 431 of the support member 43 along the thickness direction (i.e., the Z direction) of the balancing valve assembly 40 falls into the first through hole 411 of the first adhesive layer 41. The number of the first through hole 431 may be one, and it is located in the central area of ​​the support member 43. The shape of the first through hole 431 may be rectangular. Of course, in other embodiments, the number of the first through holes 431 may also be multiple, and the multiple first through holes 431 may be arranged at intervals on the support member 43, and at least part of the first through holes 431 in the multiple first through holes 431 along the thickness direction (i.e., the Z direction) of the balancing valve assembly 40 The projection falls into the first through hole 411 of the first adhesive layer 41. The shape of the first through hole 431 may also be other shapes such as a circle, a polygon, etc. This embodiment does not strictly require the shape, number, position, and size of the first through hole 431.

[0136] The second adhesive layer 42 is located in the receiving groove 17 of the inner shell 16, and is connected to the surface of the support member 43 away from the waterproof breathable membrane 45. The second adhesive layer 42 has a second through hole 421, and the second through hole 421 of the second adhesive layer 42 penetrates the second adhesive layer 42 along the thickness direction of the second adhesive layer 42. The second through hole 421 of the second adhesive layer 42 can be arranged opposite to the second opening 122 of the pressure relief channel 12 in the Z direction, and is connected to the first through hole 431 of the support member 43. Therefore, by setting the second through hole 421, on the basis of the adhesive performance that can be achieved by the second adhesive layer 42, the gas passing through the support member 43 can pass through, so that the second adhesive layer 42 has the dual functions of adhesion and gas circulation.

[0137] Exemplarily, the material of the second adhesive layer 42 may be adhesive. At least part of the projection of the second through hole 421 of the second adhesive layer 42 along the thickness direction (i.e., Z direction) of the balancing valve assembly 40 falls into the first through hole 431 of the support member 43. The number of the second through hole 421 may be one, and it is located in the central area of ​​the second adhesive layer 42. The shape of the second through hole 421 may be rectangular. Of course, in other embodiments, the number of the second through holes 421 may also be multiple, and the multiple second through holes 421 may be arranged at intervals on the second adhesive layer 42, and at least part of the second through holes 421 in the multiple second through holes 421 along the thickness direction (i.e., Z direction) of the balancing valve assembly 40 The projection falls into the first through hole 431 of the support member 43. The shape of the second through hole 421 may also be other shapes such as a circle, a polygon, etc. This embodiment does not strictly require the shape, number, position, and size of the second through hole 421.

[0138] Of course, in other embodiments, the support member 43 may not be provided between the waterproof breathable membrane 45 and the reinforcement member 46, but only the second adhesive layer 42 may be provided, and there is no strict limitation to this.

[0139] The reinforcement member 46 is located in the receiving groove 17 of the inner shell 16 and is connected to the surface of the second adhesive layer 42 away from the support member 43. The reinforcement member 46 can be fixed to the waterproof breathable membrane 45 through the second adhesive layer 42. Among them, the strength of the reinforcement member 46 can be greater than the strength of the waterproof breathable membrane 45. The strength of the reinforcement member 46 refers to the ability of the reinforcement member 46 to resist being damaged by external forces, and the strength of the waterproof breathable membrane 45 refers to the ability of the waterproof breathable membrane 45 to resist being damaged by external forces. The reinforcement member 46 can be any structural member with good strength and structural rigidity. Exemplarily, the material of the reinforcement member 46 can be metal. Or, the material of the reinforcement member 46 can be PET plastic. Of course, the reinforcement member 46 can be replaced by other types of materials with similar functions, and there is no strict restriction on this.

[0140] It is understandable that, since the waterproof breathable membrane 45 has a low structural strength and is fixed to the inner shell 16 by bonding, if no additional reinforcement structure is provided in the balancing valve assembly 40 to enhance the structural strength of the waterproof breathable membrane 45, when the wearable device 100 is in an underwater scene, water enters the wearable device 100 through the vent hole 11 and the pressure relief channel 12, causing the waterproof breathable membrane 45 inside the wearable device 100 to be subjected to a large pressure, which may easily cause the waterproof breathable membrane 45 to deform due to pressure. When the deformation is particularly large, the waterproof breathable membrane 45 will produce micro cracks or even macro cracks and fail, thereby causing the water flow outside the wearable device 100 to enter the device through the failed waterproof breathable membrane 45, causing damage to the electronic components and / or mechanical structure inside the device.

[0141] Therefore, the reinforcement 46 is provided to provide certain support performance and protection for the waterproof breathable membrane 45, so that the waterproof breathable membrane 45 can be supported by the reinforcement 46 after being deformed to a certain extent, effectively preventing the waterproof breathable membrane 45 from failing due to excessive deformation, thereby ensuring the working reliability of the waterproof breathable membrane 45.

[0142] The reinforcement member 46 has a plurality of second via holes 461, and the plurality of second via holes 461 are arranged at intervals on the reinforcement member 46. Each second via hole 461 of the reinforcement member 46 penetrates the reinforcement member 46 along the thickness direction of the reinforcement member 46. At least some of the second via holes 461 among the plurality of second via holes 461 can be arranged opposite to the second opening 122 of the pressure relief channel 12 in the Z direction, and communicate with the second through hole 421 of the second adhesive layer 42. Thus, by providing the second via holes 461, the gas passing through the second adhesive layer 42 can be allowed to pass through on the basis of the support and protection performance of the waterproof breathable membrane 45 that can be achieved by the reinforcement member 46, so that the reinforcement member 46 has the dual functions of support and gas circulation.

[0143] Exemplarily, the plurality of second vias 461 of the reinforcement 46 may be located in the central area of ​​the reinforcement 46. The projection of at least some of the plurality of second vias 461 of the reinforcement 46 along the thickness direction (i.e., the Z direction) of the balancing valve assembly 40 falls into the second through hole 421 of the second adhesive layer 42. The plurality of second vias 461 may be arranged in an array and arranged corresponding to the second opening 122 of the pressure relief channel 12, and each second via 461 may be a micropore, so that the plurality of second vias 461 form an array of micropores. By providing a plurality of second vias 461 and making the second vias 461 a micropore structure, it is possible to avoid excessive weakening of the structure of the reinforcement 46, thereby improving the strength and structural rigidity of the reinforcement 46, and facilitating the flow of air. Of course, in other embodiments, the number of the second vias 461 may also be one and the cross-sectional area (cross-sectional area along the XY plane) of the second via 461 may be greater than or equal to the cross-sectional area of ​​the second opening 122 of the pressure relief channel 12. The second via hole 461 may also be in other shapes such as a circle, a polygon, etc. This embodiment does not impose strict requirements on the shape, number, position, size, etc. of the second via hole 461 .

[0144] The third adhesive layer 44 is located in the receiving groove 17 of the inner shell 16, and is connected to the surface of the reinforcement 46 away from the second adhesive layer 42. The third adhesive layer 44 has a third through hole 441, and the third through hole 441 of the third adhesive layer 44 penetrates the third adhesive layer 44 along the thickness direction of the third adhesive layer 44. The third through hole 441 of the third adhesive layer 44 can be arranged opposite to the second opening 122 of the pressure relief channel 12 in the Z direction, and communicate with at least part of the second through holes 461 of the plurality of second through holes 461. Therefore, by setting the third through hole 441, on the basis of the adhesive performance that can be achieved by the third adhesive layer 44, the gas passing through the reinforcement 46 can pass through, so that the third adhesive layer 44 has the dual functions of adhesion and gas circulation.

[0145] Exemplarily, the material of the third adhesive layer 44 may be adhesive. At least part of the projection of the third through hole 441 of the third adhesive layer 44 along the thickness direction (i.e., Z direction) of the balancing valve assembly 40 falls into the multiple second through holes 461 of the reinforcement 46. The number of the third through hole 441 may be one, and it is located in the central area of ​​the third adhesive layer 44. The shape of the third through hole 441 may be rectangular. Of course, in other embodiments, the number of the third through holes 441 may also be multiple, and the multiple third through holes 441 may be arranged at intervals on the third adhesive layer 44, and at least part of the third through holes 441 in the multiple third through holes 441 along the thickness direction (i.e., Z direction) of the balancing valve assembly 40 The projection falls into the multiple second through holes 461 of the reinforcement 46. The shape of the third through hole 441 may also be other shapes such as a circle, a polygon, etc. This embodiment does not strictly require the shape, number, position, and size of the third through hole 441.

[0146] The buffer 47 is located in the receiving groove 17 of the inner shell 16 and is connected to the surface of the third adhesive layer 44 away from the reinforcing member 46. The buffer 47 can be fixed to the reinforcing member 46 through the third adhesive layer 44. The buffer 47 can be a structural member with good elastic properties, which can be compressed and elastically deformed after being pressed, and rebound after the pressure is removed. Exemplarily, the buffer 47 can be foam. Of course, the buffer 47 can be replaced by other types of materials with similar functions, and there is no strict limitation on this.

[0147] It can be understood that the buffer member 47 is located in the gap between the fixed bracket 48 and the waterproof breathable membrane 45, and by utilizing the good elastic properties of the buffer member 47, the height of the buffer member 47 can be fully adapted to the gap height between the third adhesive layer 44 and the fixed bracket 48, so as to achieve the purpose of eliminating the gap between the fixed bracket 48 and the waterproof breathable membrane 45, and facilitate the fixed bracket 48 to better press the waterproof breathable membrane 45 onto the inner shell 16.

[0148] The buffer 47 has a third via hole 471, and the third via hole 471 of the buffer 47 penetrates the buffer 47 along the thickness direction of the buffer 47. The third via hole 471 of the buffer 47 can be arranged opposite to the second opening 122 of the pressure relief channel 12 in the Z direction, and communicate with the third through hole 441 of the third adhesive layer 44. Therefore, by providing the third via hole 471, the gas passing through the third adhesive layer 44 can pass through on the basis of the buffering performance that the buffer 47 can achieve, so that the buffer 47 has the dual functions of buffering and gas circulation.

[0149] Exemplarily, the third through hole 471 of the buffer 47 may be located in the central area of ​​the buffer 47. The projection of at least part of the third through hole 471 of the buffer 47 along the thickness direction (i.e., the Z direction) of the balancing valve assembly 40 falls into the third through hole 441 of the third adhesive layer 44. The number of the third through hole 471 may be one, and it is located in the central area of ​​the buffer 47. The shape of the third through hole 471 may be rectangular. Of course, in other embodiments, the number of the third through holes 471 may also be multiple, and the multiple third through holes 471 may be arranged at intervals on the buffer 47, and at least part of the third through holes 471 in the multiple third through holes 471 may be projected along the thickness direction (i.e., the Z direction) of the balancing valve assembly 40, and fall into the third through hole 441 of the third adhesive layer 44. The shape of the third through hole 471 may also be other shapes such as a circle, a polygon, etc. This embodiment does not strictly require the shape, number, position, and size of the third through hole 471.

[0150] The fixed bracket 48 is located outside the receiving groove 17 of the inner shell 16, and is connected to the surface of the buffer 47 facing away from the third adhesive layer 44. The fixed bracket 48 is fixedly connected to the inner shell 16, so that the other structural parts in the balancing valve assembly 40 can be pressed and limited on the inner shell 16. On the one hand, the fixed bracket 48 has a simple structure, is easy to manufacture, occupies a small space, has a great advantage in terms of cost, and can meet the development needs of miniaturization and thinning of the wearable device 100. On the other hand, by using the fixed bracket 48 to form a reliable fixation between the other structural parts in the balancing valve assembly 40 and the inner shell 16, it is possible to avoid the problem of failure of the balancing valve assembly 40 due to sliding or movement of other structural parts in the balancing valve assembly 40, and the reliability is better.

[0151] Exemplarily, the fixing bracket 48 can be connected with the inner shell 16 by clamping, such as in the fixing bracket 48 and the inner shell 16, one is provided with a protrusion and the other is provided with a groove, and the fixing bracket 48 and the inner shell 16 are clamped by the cooperation of the protrusion and the groove. Alternatively, the fixing bracket 48 can be locked with the inner shell 16 by screws. The material of the fixing bracket 48 can be metal, which can be formed by a stamping and bending process, and the processing is relatively convenient. Alternatively, the material of the fixing bracket 48 can be plastic. Of course, the fixing bracket 48 can be replaced by other types of materials with similar functions, and there is no strict restriction on this.

[0152] The fixing bracket 48 has a fourth through hole 481, which penetrates the fixing bracket 48 along the thickness direction of the fixing bracket 48. The fourth through hole 481 of the fixing bracket 48 can be arranged opposite to the second opening 122 of the pressure relief channel 12 in the Z direction, and communicates with the third through hole 471 of the buffer 47. Therefore, by providing the fourth through hole 481, the gas passing through the buffer 47 can pass through on the basis of the compression performance that the fixing bracket 48 can achieve, so that the fixing bracket 48 has the dual functions of buffering and gas circulation.

[0153] Exemplarily, the fourth through hole 481 of the fixed bracket 48 may be located in the central area of ​​the fixed bracket 48. The projection of at least part of the fourth through hole 481 of the fixed bracket 48 along the thickness direction (i.e., the Z direction) of the balancing valve assembly 40 falls into the third through hole 471 of the buffer 47. The number of the fourth through hole 481 may be one, and it is located in the central area of ​​the fixed bracket 48. The shape of the fourth through hole 481 may be rectangular. Of course, in other embodiments, the number of the fourth through hole 481 may also be multiple, and the multiple fourth through holes 481 may be arranged at intervals on the fixed bracket 48, and at least part of the fourth through holes 481 in the multiple fourth through holes 481 along the thickness direction (i.e., the Z direction) of the balancing valve assembly 40 The projection falls into the third through hole 471 of the buffer 47. The shape of the fourth through hole 481 may also be other shapes such as a circle, a polygon, etc. This embodiment does not strictly require the shape, number, position, and size of the fourth through hole 481.

[0154] It can be understood that in this embodiment, the waterproof breathable membrane 45 can cover the second opening 122 of the pressure relief channel 12, so that the gas in the pressure relief channel 12 can be guided to the waterproof breathable membrane 45. The microstructure of the waterproof breathable membrane 45 makes it waterproof and breathable, which can facilitate the passage of gas. In addition, since the present embodiment also sequentially arranges a reinforcing member 46, a buffer member 47 and a fixed bracket 48 on the side of the waterproof breathable membrane 45 away from the second opening 122 of the pressure relief channel 12, the reinforcing member 46 can support the waterproof breathable membrane 45, the buffer member 47 can eliminate the gap between the waterproof breathable membrane 45 and the fixed bracket 48, and the fixed bracket 48 can press the buffer member 47 to fasten the balancing valve assembly 40 to the inner shell 16. Through the continuous stacking of the various structures in the balancing valve assembly 40, the balancing valve assembly 40 can have good contact performance with the inner shell 16 on the basis of ensuring the waterproof and breathable performance of the balancing valve assembly 40.

[0155] Since each layer of the balancing valve assembly 40 is provided with a hole for ventilation at a position corresponding to the second opening 122 of the pressure relief channel 12, when in use, it can block water and allow gas to smoothly pass through the waterproof and breathable membrane 45 and through the balancing valve assembly 40 into the wearable device 100, thereby balancing the internal and external air pressures of the wearable device 100.

[0156] See also Fig.11 , Fig.11 yes Figure 1A partial structural diagram of the wearable device 100 shown. In this embodiment, the wearable device 100 may also include a battery 50, a motor module 60, a button module 70 and a speaker module 80. The battery 50 is used to provide power to the wearable device 100, the motor module 60 is used to provide vibration feedback to the user, the button module is used for the user to input buttons, and the speaker module 80 is used to realize the sound of the wearable device 100.

[0157] Specifically, the battery 50 can be located in the installation space surrounded by the inner shell 16, the motor module 60 is fixed to the inner shell 16, and is located on the same side of the battery 50 as the balance valve assembly 40. The button module 70 is arranged through the inner shell 16 and the outer shell 15, and the speaker module 80 is fixed to the inner shell 16 and is located on the same side of the battery 50 as the button module 70, and is located on a different side of the battery 50 from the motor module 60 and the balance valve assembly 40. Exemplarily, the motor module 60 and the balance valve assembly 40 can be located on the short side of the inner shell 16. The speaker module 80 and the button module 70 can be located on the long side of the inner shell 16.

[0158] Second embodiment:

[0159] Please refer to Fig.12 and Fig.13 , Fig.12 is along Figure 1 A schematic cross-sectional view of another partial structure obtained by cutting along the cutting line BB shown in FIG. Fig.13 4 is an exploded schematic diagram of a balancing valve assembly 40 provided in the second embodiment of the present application. In this embodiment, the same contents as those in the first embodiment are not repeated. Unlike the first embodiment, the balancing valve assembly 40 may include a first adhesive layer 41, a support member 43, a waterproof breathable membrane 45, and a clamping bracket 49. The first adhesive layer 41, the waterproof breathable membrane 45, the support member 43, and the clamping bracket 49 may be stacked in sequence along the X direction or the Z direction. In other words, in this embodiment, the stacking direction of each structure in the balancing valve assembly 40 is stacked along the Z direction or along the X direction.

[0160] The following will only take the stacking arrangement of the balancing valve assembly 40 along the Z direction as an example for explanation. The relevant instructions for the stacking arrangement along the X direction can refer to the first embodiment above, and the various structures in the balancing valve assembly 40 described below can be applied to the wearable device 100 provided in the first embodiment without conflict.

[0161] The first adhesive layer 41 is located in the receiving groove 17 of the inner shell 16, and the first adhesive layer 41 is connected to the connecting surface 161 of the receiving groove 17. The first adhesive layer 41 has a first through hole 411, and the first through hole 411 of the first adhesive layer 41 penetrates the first adhesive layer 41 along the thickness direction of the first adhesive layer 41. The first through hole 411 of the first adhesive layer 41 can be arranged opposite to the second opening 122 of the pressure relief channel 12 in the Z direction, and connected to each other. Therefore, by setting the first through hole 411, the gas in the pressure relief channel 12 can pass through on the basis of the bonding performance that can be achieved by the first adhesive layer 41, so that the first adhesive layer 41 has the dual functions of both adhesion and gas circulation.

[0162] Exemplarily, the material of the first adhesive layer 41 may be adhesive or foam adhesive. The projection of the first through hole 411 of the first adhesive layer 41 along the Z direction at least partially falls into the second opening 122 of the pressure relief channel 12. The number of the first through hole 411 may be one, and it is located in the central area of ​​the first adhesive layer 41. The shape of the first through hole 411 may be rectangular. Of course, in other embodiments, the number of the first through holes 411 may also be multiple, and the multiple first through holes 411 may be arranged at intervals on the first adhesive layer 41, and at least some of the multiple first through holes 411 are connected to the second opening 122 of the pressure relief channel 12. The shape of the first through hole 411 may also be other shapes such as a circle, a polygon, etc. This embodiment does not make strict requirements on the shape, number, position and size of the first through hole 411.

[0163] The waterproof breathable membrane 45 is located in the receiving groove 17 of the inner shell 16, connected to the surface of the first adhesive layer 41 away from the connecting surface 161, and covers the first through hole 411 of the first adhesive layer 41. The waterproof breathable membrane 45 can be fixed to the inner shell 16 through the first adhesive layer 41. Among them, the waterproof breathable membrane 45 refers to a polymer waterproof material that allows air to pass through and prevents water from passing through. Exemplarily, the waterproof breathable membrane 45 can be a TPU (Thermoplastic polyurethanes, thermoplastic polyurethane elastomer rubber) expanded film, PE (polyethylene, polyethylene) film, PET (Polyethylene terephthalate, polyethylene terephthalate) film, PTFE (Polytetrafluoroethylene, polytetrafluoroethylene) expanded film, etc. Of course, the waterproof breathable membrane 45 in this embodiment is not limited to the materials listed above, as long as the physical film layer formed by the material with waterproof and breathable functions is within the scope of protection requested in this embodiment.

[0164] It is understandable that by providing the first adhesive layer 41 between the waterproof breathable membrane 45 and the inner shell 16, the first adhesive layer 41 can be used to improve the connection reliability between the waterproof breathable membrane 45 and the housing 10, and improve the waterproof performance between the waterproof breathable membrane 45 and the inner shell 16. Of course, in other embodiments, the waterproof breathable membrane 45 can also be fixed to the connection surface 161 of the inner shell 16 by other fixing members to achieve a detachable connection with the inner shell 16, which is convenient for the removal and replacement of the waterproof breathable membrane 45, and there is no strict limitation on this.

[0165] The projection of the waterproof breathable membrane 45 along the thickness direction (i.e., Z direction) of the balancing valve assembly 40 can cover the second opening 122 of the pressure relief channel 12, so that the waterproof breathable membrane 45 completely blocks the second opening 122 of the pressure relief channel 12. Under this setting, the gas flowing out through the second opening 122 of the pressure relief channel 12 can reach the waterproof breathable membrane 45 and pass through the waterproof breathable membrane 45 after passing through the first through hole 411 of the first adhesive layer 41.

[0166] In a possible implementation, a hydrophobic layer and / or an oleophobic layer may be provided on the surface of the waterproof breathable membrane 45. For example, a hydrophobic agent, an oleophobic agent or other materials may be coated on the surface of the waterproof breathable membrane 45 to achieve better breathability, waterproofness and dustproofness to meet different application scenarios.

[0167] In this embodiment, the second adhesive layer 42 is located in the receiving groove 17 of the inner shell 16 and is connected to the surface of the waterproof breathable membrane 45 away from the first adhesive layer 41. The second adhesive layer 42 has a second through hole 421, and the second through hole 421 of the second adhesive layer 42 penetrates the second adhesive layer 42 along the thickness direction of the second adhesive layer 42. The second through hole 421 of the second adhesive layer 42 can be arranged relative to the second opening 122 of the pressure relief channel 12 in the Z direction. Therefore, by setting the second through hole 421, on the basis of the bonding performance that can be achieved by the second adhesive layer 42, the gas passing through the waterproof breathable membrane 45 can pass through, so that the second adhesive layer 42 has the dual functions of adhesion and gas circulation.

[0168] Exemplarily, the material of the second adhesive layer 42 may be adhesive or foam adhesive. At least part of the projection of the second through hole 421 of the second adhesive layer 42 along the thickness direction (i.e., Z direction) of the balancing valve assembly 40 falls into the first through hole 411 of the first adhesive layer 41. The number of the second through hole 421 may be one, and it is located in the central area of ​​the second adhesive layer 42. The shape of the second through hole 421 may be rectangular. Of course, in other embodiments, the number of the second through holes 421 may also be multiple, and the multiple second through holes 421 may be arranged at intervals on the second adhesive layer 42, and at least part of the second through holes 421 in the multiple second through holes 421 along the thickness direction (i.e., Z direction) of the balancing valve assembly 40 The projection falls into the first through hole 411 of the first adhesive layer 41. The shape of the second through hole 421 may also be other shapes such as a circle, a polygon, etc. This embodiment does not strictly require the shape, number, position, and size of the second through hole 421.

[0169] The compression bracket 49 is located in the receiving groove 17 of the inner shell 16 and is connected to the surface of the second adhesive layer 42 away from the waterproof breathable membrane 45. The compression bracket 49 can be fixed to the waterproof breathable membrane 45 through the second adhesive layer 42. Among them, the strength of the compression bracket 49 can be greater than the strength of the waterproof breathable membrane 45. The strength of the compression bracket 49 refers to the ability of the compression bracket 49 to resist being damaged by external forces, and the strength of the waterproof breathable membrane 45 refers to the ability of the waterproof breathable membrane 45 to resist being damaged by external forces. The compression bracket 49 can be any structural member with good strength and structural rigidity. Exemplarily, the material of the compression bracket 49 can be metal. Alternatively, the material of the compression bracket 49 can be PET plastic. Of course, the compression bracket 49 can be replaced by other types of materials with similar functions, and there is no strict restriction on this.

[0170] It is understandable that, since the waterproof breathable membrane 45 has a low structural strength and the waterproof breathable membrane 45 is fixed to the inner shell 16 by bonding. If no additional reinforcement structure is provided in the balancing valve assembly 40 to enhance the structural strength of the waterproof breathable membrane 45, when the wearable device 100 is in a water scene, water enters the wearable device 100 through the vent 11 and the pressure relief channel 12, causing the waterproof breathable membrane 45 inside the wearable device 100 to be subjected to a large pressure, which may easily cause the waterproof breathable membrane 45 to deform due to pressure. When the deformation is particularly large, the waterproof breathable membrane 45 may produce micro cracks or even macro cracks. For example, excessive water pressure may cause the waterproof breathable membrane 45 to rupture, the waterproof breathable membrane 45 may fall off from the vent 11, etc., and then the water flow outside the wearable device 100 may enter the device through the failed waterproof breathable membrane 45, causing damage to the electronic components and / or mechanical structure inside the device.

[0171] Therefore, the clamping bracket 49 is provided to provide certain support performance and protection for the waterproof breathable membrane 45, so that the waterproof breathable membrane 45 can be supported by the clamping bracket 49 after being deformed to a certain extent, effectively preventing the waterproof breathable membrane 45 from failing due to excessive deformation, thereby ensuring the working reliability of the waterproof breathable membrane 45.

[0172] The compression bracket 49 has a plurality of perforations 491, and the plurality of perforations 491 are arranged at intervals on the compression bracket 49. Each perforation 491 of the compression bracket 49 penetrates the compression bracket 49 along the thickness direction of the compression bracket 49. At least some of the plurality of perforations 491 can be arranged opposite to the second opening 122 of the pressure relief channel 12 in the Z direction, and communicate with the second through hole 421 of the second adhesive layer 42. Thus, by providing the perforations 491, on the basis of the support and protection performance of the waterproof breathable membrane 45 that can be achieved by the compression bracket 49, the gas passing through the second adhesive layer 42 can be allowed to pass, so that the compression bracket 49 has both the function of supporting and providing gas circulation.

[0173] Exemplarily, the plurality of perforations 491 of the clamping bracket 49 may be located in the central area of ​​the clamping bracket 49. The projection of at least some of the plurality of perforations 491 of the clamping bracket 49 along the thickness direction (i.e., the Z direction) of the balancing valve assembly 40 falls into the second through hole 421 of the second adhesive layer 42. The plurality of perforations 491 may be arranged in an array and arranged corresponding to the second opening 122 of the pressure relief channel 12, and each perforation 491 may be a micropore, so that the plurality of perforations 491 form an array of micropores. By providing a plurality of perforations 491 and making the perforations 491 a microporous structure, it is possible to avoid excessive weakening of the structure of the clamping bracket 49, thereby improving the strength and structural rigidity of the clamping bracket 49, and facilitating the flow of air. Of course, in other embodiments, the number of perforations 491 may also be one and the cross-sectional area (cross-sectional area along the XY plane) of the perforation 491 may be greater than or equal to the cross-sectional area of ​​the second opening 122 of the pressure relief channel 12. The shape of the through hole 491 may also be other shapes such as a circle, a polygon, etc. This embodiment does not impose strict requirements on the shape, number, position, and size of the through hole 491 .

[0174] In this embodiment, the clamping bracket 49 is also fixedly connected to the inner shell 16, so that other structural parts in the balancing valve assembly 40 can be clamped and limited on the inner shell 16. On the one hand, the clamping bracket 49 has a simple structure, is easy to manufacture, occupies a small space, has a great advantage in terms of cost, and can meet the development needs of miniaturization and thinning of the wearable device 100. On the other hand, by clamping the bracket 49, other structural parts in the balancing valve assembly 40 are reliably fixed to the inner shell 16, which can avoid the problem of failure of the balancing valve assembly 40 due to sliding or movement of other structural parts in the balancing valve assembly 40, and has better reliability.

[0175] Exemplarily, the clamping bracket 49 can be connected with the inner shell 16 by clamping, such as in the clamping bracket 49 and the inner shell 16, one is provided with a protrusion and the other is provided with a groove, and the clamping bracket 49 and the inner shell 16 are clamped by the cooperation of the protrusion and the groove. Alternatively, the clamping bracket 49 can be locked with the inner shell 16 by screws. The material of the clamping bracket 49 can be metal, which can be formed by a stamping and bending process, and the processing is relatively convenient. Alternatively, the material of the clamping bracket 49 can be plastic. Of course, the clamping bracket 49 can be replaced by other types of materials with similar functions, and there is no strict limitation on this.

[0176] Based on the above description, it should be understood that, compared with the first embodiment, which requires the use of a reinforcement member 46 and a fixing bracket 48 to cooperate to play the role of breathable support and fixed compression, in this embodiment, the compression bracket 49 can achieve the role of breathable support and fixed compression only through the structural design of one part, saving the cost of one part, which is conducive to reducing the overall cost of the balancing valve assembly 40. In addition, compared with the solution of the first embodiment, the solution of this embodiment can make the thickness of the balancing valve assembly 40 thinner and lighter due to the stacking arrangement along the Z direction and the number of stacking layers is small, thereby reducing the space size of the wearable device 100 occupied by the balancing valve assembly 40 in the Z direction. Therefore, compared with the solution of the first embodiment, the stacking design of the balancing valve assembly 40 adopted in this embodiment can better adapt to the development trend of thinning of the wearable device 100, and release more space in the Z direction for the main board to arrange the components when the battery 50 is relatively thin.

[0177] In this embodiment, at least one of the first adhesive layer 41 and the second adhesive layer 42 is a foam adhesive layer. Under this setting, at least one of the first adhesive layer 41 and the second adhesive layer 42 is an elastic adhesive layer with good elastic properties, which can be compressed and elastically deformed after being pressed, and rebound after the pressure is removed. By utilizing the good elastic properties of the foam adhesive layer, the height of the foam adhesive layer can be fully adapted to the height of the gap between the second adhesive layer 42 and the fixed bracket 48, so as to achieve the purpose of eliminating the gap between the fixed bracket 48 and the waterproof breathable membrane 45, which not only facilitates the fixed bracket 48 to better press the waterproof breathable membrane 45 onto the inner shell 16, but also plays the role of interference compression and waterproofing. Of course, at least one of the first adhesive layer 41 and the second adhesive layer 42 can also be replaced by other types of materials with similar functions, and there is no strict restriction on this.

[0178] It should be noted that the bonding layer between the compression bracket 49 and the inner shell 16 may be more than the two layers (the first bonding layer and the second bonding layer) mentioned above, and it may be more than two layers. At least one bonding layer is required on both sides of the waterproof and breathable membrane 45 along the Z direction to ensure the connection strength with the inner shell 16 and the compression bracket 49. This embodiment does not impose strict restrictions on the number of bonding layers between the compression bracket 49 and the inner shell 16.

[0179] In a possible implementation, Fig.12 As shown, the first adhesive layer 41, the waterproof breathable membrane 45, and the second adhesive layer 42 are all located in the receiving groove 17. The clamping bracket 49 may include a body 492, a first connecting arm 493, and a second connecting arm 494. The body 492 of the clamping bracket 49 covers the opening of the receiving groove 17 and limits the first adhesive layer 41, the waterproof breathable membrane 45, and the second adhesive layer 42 in the receiving groove 17. The first connecting arm 493 of the clamping bracket 49 is connected to one end of the body 492 and is clamped or screwed with the inner shell 16. The second connecting arm of the clamping bracket 49 is connected to the other end of the body 492 and is clamped or screwed with the inner shell 16.

[0180] Under this arrangement, the clamping bracket 49 can be detachably connected to the inner shell 16 as a whole, which facilitates the rapid assembly of the clamping bracket 49 to the inner shell 16 and removal from the inner shell 16, thereby improving the installation efficiency and reliability between the balancing valve assembly 40 and the inner shell 16.

[0181] It can be understood that in this embodiment, the waterproof breathable membrane 45 can cover the second opening 122 of the pressure relief channel 12, so that the gas in the pressure relief channel 12 can be guided to the waterproof breathable membrane 45. The microstructure of the waterproof breathable membrane 45 makes it waterproof and breathable, which can facilitate the passage of gas. In addition, since the present embodiment also provides a clamping bracket 49 on the side of the waterproof breathable membrane 45 away from the second opening 122 of the pressure relief channel 12, the clamping bracket 49 can play the role of supporting the waterproof breathable membrane 45, as well as a breathable support, and fastening the balancing valve assembly 40 to the inner shell 16. Through the continuous stacking of the various structures in the balancing valve assembly 40, the balancing valve assembly 40 can have good contact performance with the inner shell 16 on the basis of ensuring the waterproof and breathable performance of the balancing valve assembly 40.

[0182] Since each layer of the balancing valve assembly 40 is provided with a hole for ventilation at a position corresponding to the second opening 122 of the pressure relief channel 12, when in use, it can block water and allow gas to smoothly pass through the waterproof and breathable membrane 45 and through the balancing valve assembly 40 into the wearable device 100, thereby balancing the internal and external air pressures of the wearable device 100.
