Description

[0001] This application is a divisional application. The application number of the original application is 202210130974.6, and the original application date is February 12, 2022. The entire content of the original application is incorporated into this application by reference. Technical Field

[0002] The present application relates to the technical field of electronic equipment, and in particular to a waterproof component and an electronic device. Background Art

[0003] The housing of an electronic device often needs to be provided with a through hole to connect the internal space of the housing with the outside air, so as to achieve a specific function. For example, the microphone in the housing of an electronic device needs to collect external sounds through the sound pickup hole; for another example, if there are devices sensitive to air pressure in the electronic device, such as speakers, the housing of the device is required to be provided with a through hole so that it can be ventilated and the air pressure inside and outside the electronic device can be balanced. In addition, electronic devices have waterproof requirements. Therefore, a waterproof and breathable membrane can usually be provided on one side of the through hole. The waterproof and breathable membrane can allow gas to pass through while preventing liquid from passing through, and has a certain waterproof performance, so it can meet the ventilation and waterproof requirements of electronic devices in daily use scenarios.

[0004] When electronic devices are used in high-pressure environments such as swimming and diving, they require higher levels of waterproofing. However, waterproof breathable membranes are easily damaged in high-pressure environments, causing water to enter the electronic device, making them unsuitable for use in high-pressure environments. Therefore, it is necessary to design a waterproof component for electronic devices that can protect the waterproof breathable membrane in high-pressure environments. Summary of the Invention

[0005] In order to solve the problem that conventional electronic devices are easily flooded and cannot work reliably in high water pressure environments, the embodiments of the present application provide a waterproof component and electronic device that can achieve product waterproofing in high water pressure environments and meet usage requirements in high water pressure environments.

[0006] In the first aspect, an embodiment of the present application provides a waterproof component, which is used to be installed to the shell of the electronic device, wherein the shell has a shell through hole connecting the inside and outside of the shell; the waterproof component includes a switch, a pressure plate, a seal and an elastic member. After the waterproof component is installed to the shell, the switch, the pressure plate, the seal and the elastic member are arranged in sequence from the outside to the inside of the shell, and the two ends of the elastic member respectively abut the pressure plate and the shell, and the seal and the shell through hole and the waterproof breathable membrane located on the side of the shell through hole facing away from the seal are arranged relative to each other; the switch can move in a first direction under the action of an external force, so that the pressure plate moves in a second direction under the joint action of the switch and the elastic member, thereby driving the seal to approach and block the shell through hole or move away from the shell through hole.

[0007] In this solution, the switch and the pressure plate can be directly connected, or indirectly contacted through other components. The movement of the switch can be transmitted to the pressure plate. The movement mode of the switch is not limited to movement and rotation. The first direction of the switch and the second direction of the pressure plate both refer to bidirectional, including forward and reverse directions. For example, the first direction can be a left-right direction, including left direction (for example, forward direction) and right direction (for example, reverse direction); or, the first direction can be a rotation direction, including clockwise direction (for example, forward direction) and counterclockwise direction (for example, reverse direction). The relationship between the first direction and the second direction can be unlimited, for example, the two can intersect (including vertical) or be parallel, etc. The number of pressure plates and seals can be at least one. The seal can be directly fixed to the pressure plate, or connected to the pressure plate through other components. A pressure plate can be directly or indirectly connected to at least one seal, and a seal can correspond to a shell through-hole. The elastic member can provide elastic restoring force to the pressure plate.

[0008] In this solution, devices that are sensitive to air pressure, such as speakers, and devices that need to be connected to the outside atmosphere, such as microphones, can be arranged in the shell. Under daily circumstances, the switch drives the pressure plate and the seal to move to loosen the shell through-hole, which can connect the inner cavity of the shell with the outside atmosphere, ensure the balance of air pressure inside and outside the electronic device, and meet the working requirements of the device. Due to the presence of a waterproof and breathable membrane, external liquids cannot enter the interior of the electronic device, so that the electronic device can be breathable and waterproof in daily scenarios. When the user wears the electronic device to swim or dive, which puts the electronic device in a high water pressure environment, the switch drives the pressure plate and the seal to move to block the shell through-hole, which can disconnect the inner cavity of the shell from the outside world, ensuring that external gas and liquid cannot enter the interior of the electronic device through the shell through-hole, so that the waterproof and breathable membrane on one side of the shell through-hole does not need to withstand high pressure and is therefore not easily damaged, so that the electronic device can work reliably in a high water pressure environment.

[0009] In one implementation of the first aspect, the first direction is perpendicular or parallel to the second direction; the switch is movable along the first direction under the action of an external force. In this solution, the switch can move substantially on the same plane (translation) or in three-dimensional space (compound motion, such as both horizontal movement and vertical movement). This solution has a simple mechanical design, meets motion transmission requirements, and occupies a small amount of structural space.

[0010] In one implementation of the first aspect, the first direction is perpendicular to the second direction; the pressure plate has an inclined pressure plate surface; and the switch is in sliding contact with the inclined pressure plate surface. This solution has a simple mechanical design, reliable mechanical movement, can meet motion transmission requirements, and occupies little structural space.

[0011] In one implementation of the first aspect, the pressure plate has a limiting groove; when the switch translates along the first direction to a first limit position, the sealing member approaches and blocks the housing through-hole, and the switch engages the limiting groove, thereby locking the switch in the first limit position. This solution ensures that the switch remains in the locked position, ensuring the sealing performance of the sealing member, and enabling the electronic device to operate reliably in high-pressure water environments.

[0012] In an implementation of the first aspect, the waterproof component includes a limiting column, which is used to be installed to the shell; a limiting groove is provided on the surface of the switch facing the limiting column; when the switch is translated to the first extreme position along the first direction, the seal approaches and blocks the through hole of the shell, and the limiting groove is clamped with the limiting column to lock the switch in the first extreme position. In this solution, the limiting column itself can undergo elastic deformation (for example, elastic expansion and contraction), and the elastic deformation of the limiting column realizes the detachable clamping of the limiting column and the limiting groove. Alternatively, the limiting column itself cannot be elastically deformed, but can be raised and lowered relative to the shell by elastic parts to realize the detachable clamping of the limiting column and the limiting groove. This solution can enable the switch to reliably maintain the locked position, ensure the sealing performance of the seal, and enable the electronic device to work reliably in a high water pressure environment.

[0013] In one implementation of the first aspect, after the limit post is mounted to the housing, the limit post can move relative to the housing in the second direction; while the switch translates along the first direction to the first extreme position, the switch can press the limit post toward the housing until the limit groove engages the limit post. This solution provides another switch locking design that similarly enables the switch to reliably maintain its locked position, ensuring the sealing performance of the seal, and enabling the electronic device to operate reliably in high-pressure water environments.

[0014] In one implementation of the first aspect, the waterproof component includes a loading frame and a limiting column elastic member; the loading frame is used to be installed on the shell and is located between the shell and the switch; the loading frame has a receiving groove, the bottom wall of the receiving groove faces the switch, and the bottom wall is provided with a receiving through-hole connected to the receiving groove; the limiting column includes a column and a limiting skirt surrounding the outer circumference of the column, a part of the column is received in the receiving groove, the end of the column is exposed from the receiving through-hole, the limiting skirt is received in the receiving groove and contacts the bottom wall; the limiting column elastic member is located in the receiving groove, the limiting column elastic member abuts against the limiting skirt and applies elastic force to the limiting skirt; during the process of the switch moving horizontally along the first direction to the first extreme position, the switch can squeeze the end to press the limiting column toward the shell until the limiting groove and the end are clamped. This solution designs a specific installation structure for the limiting column, which has a simple and reliable structural design, high mass production, and can meet product requirements.

[0015] In one implementation of the first aspect, the switch has a switch inclined surface that is in sliding contact with the pressing plate inclined surface. In this solution, the switch also has an inclined surface, and the sliding contact between the switch inclined surface and the pressing plate inclined surface has the advantages of smooth movement and less wear on the pressing plate.

[0016] In an implementation of the first aspect, the switch can rotate in a first direction under the action of an external force, and the pressure plate is in sliding contact with the switch. This solution has a simple mechanism design and reliable mechanism movement, can meet the requirements of motion transmission, and meet specific product requirements.

[0017] In one implementation of the first aspect, the switch has a cam surface, wherein the cam radius at various positions on the cam surface varies, and the cam surface is in sliding contact with the pressure plate. As the switch rotates in the first direction, the cam radius of the positions on the cam surface that sequentially contact the pressure plate gradually increases, thereby causing the seal to approach and seal the housing through-hole; alternatively, the cam radius of the positions on the cam surface that sequentially contact the pressure plate gradually decreases, thereby causing the seal to move away from the housing through-hole. In this solution, the switch and the pressure plate can form a cam mechanism, which has a simple design and reliable movement, can meet motion transmission requirements, and can satisfy specific product requirements.

[0018] In one implementation of the first aspect, the waterproof component includes a bracket and a pin; a local area of ​​the bracket is hollowed out to form a receiving space, and the bracket is used to be fixed to the housing; the pin passes through the receiving space and is fixed to the bracket, and the pin passes through the switch and is rotatably connected to the switch; when the switch rotates to the extreme position along the first direction, the switch contacts the bracket, and the position on the switch that contacts the bracket and the position on the switch that contacts the pressure plate are respectively located on both sides of the pin. In this solution, when the switch rotates to the extreme position (the seal blocks the housing through hole or is away from the housing through hole), the bracket and the pressure plate apply a reverse torque to the switch, so that the switch can maintain a balanced state, thereby being reliably locked in the extreme position. Therefore, this solution can ensure the sealing performance of the seal, so that the electronic device can work reliably in a high water pressure environment.

[0019] In one implementation of the first aspect, when the switch moves along the first direction until the seal approaches and blocks the housing through hole, at least a portion of the projection of the force-bearing position on the pressure plate along the center line of the housing through hole falls into the housing through hole, wherein the force-bearing position is subjected to force to cause the pressure plate to move along the second direction. In this solution, the switch and the pressure plate can be in direct contact or indirect contact. For direct contact, when the switch is in the waterproof limit position, the force-bearing position on the pressure plate is also the force-applying position of the switch on the pressure plate. At least a portion of the projection of the force-applying position of the switch along the center line of the housing through hole falls into the housing through hole, so that the force-applying position and the position of the sealing head can be relative (for example, facing each other) in the direction of the center line of the housing through hole, so that the sealing head is not easily lifted. For indirect contact, when the switch is in the waterproof limit position, the force-bearing position on the pressure plate is also the force-applying position of the intermediate component between the switch and the pressure plate on the pressure plate. At least part of the projection of the force-applying position of the intermediate component along the center line of the shell through hole falls into the shell through hole, so that the force-applying position and the position of the sealing head can be relative (for example, facing) in the direction of the center line of the shell through hole, so that the sealing head is not easy to tilt up.

[0020] In one implementation of the first aspect, the waterproof assembly includes a bracket, which is used to be fixed to the housing and integrally mount the waterproof assembly to the housing. The bracket houses other components of the waterproof assembly, making the waterproof assembly compact and ensuring the structural and appearance integrity of the electronic device. The bracket may also support and secure other components of the waterproof assembly.

[0021] In a second aspect, an embodiment of the present application provides a waterproof component of an electronic device, which is used to be installed in a shell of the electronic device, wherein the shell has a shell through hole, and the shell through hole is connected to the interior of the shell through a waterproof breathable membrane; the waterproof component includes a bar tube, a switch and a switch sealing ring; the bar tube has a bar tube inner cavity and a bar tube connecting hole connected to the bar tube inner cavity; the switch can be movably installed in the bar tube inner cavity, and the switch has a switch connecting hole connected to the outside of the switch; the switch sealing ring is fixed to the outer periphery of the switch, and is located in the bar tube inner cavity and abuts against the cavity wall of the bar tube inner cavity; after the waterproof component is installed in the shell, the bar tube connecting hole is connected to one end of the shell through hole facing away from the waterproof breathable membrane; the switch is used to be moved relative to the bar tube under the action of external force, so that the switch connecting hole is connected to the bar tube connecting hole, or the switch connecting hole is staggered with the bar tube connecting hole and the switch sealing ring is sealed between the switch connecting hole and the bar tube connecting hole. This solution uses the movement of a switch to switch the waterproof component between connected and disconnected states, ensuring reliable operation of electronic devices in both everyday environments and high-pressure water environments. This solution can be applied to smart watches, where the switch can serve as a knob button on the smart watch.

[0022] In an implementation of the second aspect, the switch has an axial switch communication hole and a radial switch communication hole. The axial switch communication hole intersects with the radial switch communication hole, and the axial switch communication hole communicates with the radial switch communication hole and the outside of the switch. The switch is used to move relative to the bar tube under an external force, so that the radial switch communication hole communicates with the bar tube communication hole, or the radial switch communication hole is错开 from the bar tube communication hole and the switch sealing ring seals between the radial switch communication hole and the bar tube communication hole. The above internal structure of the switch can meet the structural design requirements of electronic devices, making the overall structure compact, the size small, and it is easy to achieve thinness and lightness.

[0023] In an implementation of the second aspect, the outer shape of the bar tube is a rotating body. The bar tube has a first mating groove, a second mating groove, and a third mating groove that are sequentially connected. The first mating groove, the second mating groove, and the third mating groove are connected into a "L" shape. The first mating groove extends along the axial direction of the bar tube, and the second mating groove extends along the circumferential direction of the bar tube. The switch has a mating protrusion. When the switch moves relative to the bar tube to the first limit position, the mating protrusion moves in the third mating groove, the second mating groove, and the first mating groove in sequence. When the switch moves relative to the bar tube in the reverse direction to the second limit position, the mating protrusion moves in the first mating groove, the second mating groove, and the third mating groove in sequence. Among them, when the switch is located at the first limit position, the radial switch communication hole is错开 from the bar tube communication hole, and the switch sealing ring seals between the radial switch communication hole and the bar tube communication hole. When the switch is located at the second limit position, the radial switch communication hole communicates with the bar tube communication hole. The above mating structure of the bar tube and the switch enables the switch to have a movement form of moving + rotating, so as to meet the structural design requirements of electronic devices.

[0024] In an implementation of the second aspect, the bar tube includes a connected head and a tube body. The head and the tube body jointly enclose the bar tube inner cavity. The first mating groove, the second mating groove, and the third mating groove are all provided on the head. The bar tube communication hole is provided on the tube body. The tube body is used to pass through and be fixed to the housing, and the head is located outside the housing. This kind of bar tube structure is simple, has good mass production performance, and can meet the structural design requirements of electronic devices.

[0025] In an implementation of the second aspect, the waterproof component includes a bar tube sealing ring, and the bar tube sealing ring is used to seal the gap between the head and the housing. This solution can prevent external liquid from entering the device interior from the bar tube and the housing, enhancing the waterproof performance of the device.

[0026] In one implementation of the second aspect, a receiving groove is formed at one end of the tube body facing away from the head, and the receiving groove is part of the inner cavity of the tubing. The waterproof assembly includes a switch stopper, which is fixed to a portion of the switch proximal to the receiving groove and protrudes from the outer circumference of the switch. When the switch moves to the first limit position, the switch stopper abuts against the bottom wall of the receiving groove. When the switch moves to the second limit position, a portion of the switch is located in the receiving groove, and a gap is formed between the switch stopper and the bottom wall of the receiving groove. The switch stopper may be, for example, a retaining spring. The switch stopper can limit the switch to prevent it from falling out of the tubing.

[0027] In one implementation of the second aspect, the waterproof assembly includes an elastic member, opposite ends of which abut against the switch and the bar tube, respectively. The elastic member can provide a rebound force to the switch, so that the user can experience tactile feedback when operating the switch.

[0028] In a third aspect, embodiments of the present application provide an electronic device comprising a housing, a waterproof breathable membrane, and any of the aforementioned waterproof components. The housing defines a housing space and has a housing through-hole, one end of which communicates with the housing space through the waterproof breathable membrane. The waterproof component is mounted to the housing and located at the end of the housing through-hole facing away from the waterproof breathable membrane. This electronic device can operate reliably in both everyday environments and high-pressure water environments.

[0029] In one implementation of the third aspect, the electronic device includes a magnet, a magnetic field sensor, and a controller; the magnet is fixed to the pressure plate in the waterproof component, or fixed to the switch in the waterproof component; the magnetic field sensor and the controller are both arranged in the housing space; the magnetic field sensor is used to sense the magnetic flux of the magnet and generate a detection signal, and the controller is used to determine the state of the waterproof component based on the detection signal. In this solution, the state of the waterproof component can include a connected state and a disconnected state. Through the magnetic field detection design, the state of the electronic device can be determined, which makes it easier for the user to know the state of the electronic device, ensure that the user correctly operates the electronic device according to the usage scenario, and enhance the user experience.

[0030] In one implementation of the third aspect, the shell is provided with a sound outlet hole, which connects the shell space with the outside of the shell; the electronic device includes a microphone and a sound-emitting device, and both the microphone and the sound-emitting device are located in the shell space; the microphone is used to pick up the sound signal transmitted through the shell through-hole and the waterproof breathable membrane; the sound-emitting device is used to emit the sound signal transmitted to the outside of the shell through the sound outlet hole. The shell through-hole can be used as a sound pickup through-hole for the microphone. The sound-emitting device is an electroacoustic device used to emit sound, for example, it can be a speaker or a buzzer. This solution can ensure the waterproof performance of the microphone and the sound-emitting device in the electronic device, ensuring normal operation even under high water pressure.

[0031] In one implementation of the third aspect, the electronic device includes a controller disposed in the housing space; the controller is configured to control the sound-emitting device to emit a set sound signal, and to determine the state of the waterproof component based on the strength of the set sound signal received by the microphone. If the signal strength received by the microphone is relatively high, it indicates that the waterproof component is in a connected state; if the signal strength received by the microphone is relatively low, it indicates that the waterproof component is in an intermediate state; and if the signal strength received by the microphone is substantially zero, it indicates that the waterproof component is in a disconnected state. The sound signal detection design enables the state of the electronic device to be determined, making it easier for the user to be informed of the state of the electronic device, ensuring that the user correctly operates the electronic device according to the usage scenario, and enhancing the user experience.

[0032] In one implementation of the third aspect, the electronic device includes a depth gauge; the controller is configured to control the sound-emitting device to emit a set sound signal when determining that the detection result of the depth gauge reaches a threshold, and to determine the state of the waterproof component based on the intensity of the set sound signal received by the microphone. When the electronic device enters a high-pressure water environment, the high pressure or other anomalies may cause the state of the waterproof component to change, potentially causing liquid to enter the electronic device. In order to promptly alert the user to this risk and prevent damage to the electronic device due to liquid intrusion, the depth of the electronic device under water can be detected by a depth gauge, and the state detection of the waterproof component can be triggered based on the detection result of the depth gauge.

[0033] In one implementation of the third aspect, the electronic device displays a prompt message that informs the user of the current status of the waterproof component. This solution enables the user to know the status of the electronic device, ensuring that the user operates the electronic device correctly according to the usage scenario, thereby enhancing the user experience.

DETAILED DESCRIPTION

[0162] The following embodiments of the present application provide an electronic device, including but not limited to wearable devices such as smart watches, smart bracelets, smart helmets, smart clothing, as well as mobile phones, tablet computers or other electronic products.

[0163] Example 1

[0164] like Figure 1 、 Figure 2 and Figure 3 As shown, the electronic device 70 of the first embodiment may include a housing 71, a waterproof component 72, and a housing 73. The housing 71 and the housing 73 may be assembled together to enclose the internal space of the electronic device 70, and the waterproof component 72 may be installed on the housing 71.

[0165] Figure 4 yes Figure 3 The schematic diagram of the local enlarged structure at A in the figure. Figure 4 As shown, the bracket 722 in the waterproof assembly 72 can be designed with an opening 722a, which connects the interior and exterior spaces of the housing 71. In other words, the opening 722a connects the interior and exterior spaces of the electronic device 70. The electronic device 70 may also include a microphone, a speaker, a waterproof breathable membrane, a magnetic field sensor, a controller, etc., which will be described in detail below.

[0166] like Figure 5 As shown, the outer shape of the shell 71 can be approximately cover-shaped. The shell 71 has a bottom wall and a peripheral side wall surrounding the periphery of the bottom. The bottom wall and the peripheral side wall can form a shell space 71a, and the shell space 71a belongs to the internal space of the electronic device 70.

[0167] Figure 6 yes Figure 5 A partial enlarged view of point B in the figure. Figure 6As shown, the outer surface of the peripheral sidewall of the housing 71 may be formed with protrusions 71b, 71d, and 71f, with protrusions 71b, 71d, and 71f spaced apart in pairs. For example, there is a gap 71h between protrusion 71b and protrusion 71d, and a gap 71g between protrusion 71d and protrusion 71f. Protrusions 71b and 71d may enclose a second receiving groove 71c, with gap 71h communicating with the second receiving groove 71c. Protrusions 71d and 71f may enclose a first receiving groove 71e, with gap 71g communicating with the first receiving groove 71e. Spacings 71h and 71g may also be referred to as vents.

[0168] Figure 7 yes Figure 6 The CC cross-sectional structure diagram of the structure shown is as follows. Figure 7 As shown, the structure of the first receiving groove 71e is similar to that of the second receiving groove 71c, but the opening area of ​​the first receiving groove 71e can be larger and the depth of the first receiving groove 71e can be larger, while the opening area of ​​the second receiving groove 71c can be smaller and the depth of the second receiving groove 71c can be smaller. This can meet the design requirements of the electroacoustic modules respectively associated with the first receiving groove 71e and the second receiving groove 71c (to be described below). In other embodiments, the structural dimensions of the first receiving groove and the second receiving groove can be designed as needed and are not limited to those shown in this embodiment. For example, the structural dimensions of the first receiving groove and the second receiving groove can be consistent.

[0169] like Figure 7 As shown, the bottom wall of the first receiving groove 71e can be provided with a shell through hole 71j, which connects the first receiving groove 71e with the shell space 71a, so that the gap 71g, the first receiving groove 71e, the shell through hole 71j and the shell space 71a are connected in sequence. The bottom wall of the second receiving groove 71c can be provided with a shell through hole 71i, which connects the second receiving groove 71c with the shell space 71a, so that the gap 71h, the second receiving groove 71c, the shell through hole 71i and the shell space 71a are connected in sequence. Figure 7 As shown, schematically, the outer peripheries of the housing through-holes 71i and 71j may form an annular groove structure, which is used to mount an elastic member (described below) in the waterproof assembly 72. In other embodiments, the outer peripheries of the housing through-holes 71i and 71j may also be flat surfaces, eliminating the need for the annular groove structure.

[0170] The above-described internal and external structures of the housing 71 are merely illustrative, and the present invention is not limited thereto. For example, the housing in other embodiments may have only one receiving slot and one housing through-hole. Alternatively, the housing may have multiple receiving slots and corresponding housing through-holes, thereby sealing the multiple housing through-holes.

[0171] like Figure 8 、 Figure 9 and Figure 10 As shown, the waterproof assembly 72 may include a bracket 722, a connector 721, a switch 723, a first pressing plate 725, a second pressing plate 726, a sealing member 727, a magnet 728 and an elastic member 724. Each of these will be described below.

[0172] like Figure 11 and Figure 12 As shown, the bracket 722 can be a generally strip-shaped cover-like structure, having an inner cavity and an opening 722b, wherein the opening 722b connects the inner cavity with the exterior of the bracket 722. Two openings 722a can be provided on a wall (e.g., a side wall) of the bracket 722, wherein the openings 722a connect the inner cavity with the exterior of the bracket 722.

[0173] Combine Figure 9 、 Figure 6 and Figure 4 As shown, when the waterproof assembly 72 is mounted to the housing 71, the bracket 722 is fixedly connected to the housing 71. For example, the bracket 722 can be fixedly connected to the housing 71 via a connector 721 (e.g., a threaded connector). The two openings 722a of the bracket 722 are respectively connected to the gaps 71h and 71g of the housing 71. Therefore, one opening 722a, the interval 71h, the second receiving groove 71c, the shell through hole 71i and the shell space 71a are connected, that is, one opening 722a, the interval 71h, the second receiving groove 71c and the shell through hole 71i form a channel (which can be called the second channel) connecting the outside of the shell 71 and the shell space 71a; another opening 722a, the interval 71g, the first receiving groove 71e, the shell through hole 71j and the shell space 71a are connected, that is, another opening 722a, the interval 71g, the first receiving groove 71e and the shell through hole 71j form another channel (which can be called the first channel) connecting the outside of the shell 71 and the shell space 71a.

[0174] like Figure 10 、 Figure 13 and Figure 14 As shown, the switch 723 can be roughly a strip-shaped cover-like structure. The switch 723 can include a sliding portion 723a and a force-applying portion 723d. The sliding portion 723a can be flat, and there can be two sliding portions 723a, and the two sliding portions 723a can be basically located in the same plane. The force-applying portion 723d can be connected between the two sliding portions 723a and protrude relative to the sliding portions 723a. A local area of ​​the force-applying portion 723d is concave to form a first receiving space 723b and a second receiving space 723c, and the first receiving space 723b and the second receiving space 723c are spaced apart. The sizes of the first receiving space 723b and the second receiving space 723c can be the same.

[0175] like Figure 14 As shown, the inner surface of the first receiving space 723b includes a first switch slope 723h, which is closer to the interior of the first receiving space 723b. A first protrusion 723g may also be formed at the opening of the first receiving space 723b. The surface of the first protrusion 723g may be a curved surface, and the surface of the first protrusion 723g may smoothly connect with the first switch slope 723h.

[0176] like Figure 14 Similarly, the inner surface of the second receiving space 723c includes a second switch slope 723f, which is closer to the interior of the second receiving space 723c. The second switch slope 723f can be parallel to the first switch slope 723h. A second protrusion 723e can also be formed at the opening of the second receiving space 723c. The surface of the second protrusion 723e can be a curved surface, and the surface of the second protrusion 723e can smoothly connect with the second switch slope 723f.

[0177] The above-mentioned internal and external structures of the switch 723 are merely illustrative, and the embodiments of the present application are not limited thereto. For example, the switch in other embodiments may have only one receiving space.

[0178] like Figure 15 and Figure 16 As shown, the first pressure plate 725 may include a substrate 725a, a receiving portion 725b and a pressure plate matching portion 725c. The substrate 725a may be roughly flat. A receiving groove 725f may be provided on one side surface of the substrate 725a (the normal of the surface may be along the thickness direction of the substrate 725a). The receiving portion 725b may be located on the same side of the substrate 725a as the receiving groove 725f, and the receiving portion 725b may form a ring-shaped structure. The pressure plate matching portion 725c may be connected to the other side of the substrate 725a, and the receiving portion 725b and the pressure plate matching portion 725c may be staggered.

[0179] like Figure 15 As shown, the outer shape of the pressure plate fitting portion 725c can be roughly a prism structure with a trapezoidal cross section. The pressure plate fitting portion 725c has a first pressure plate inclined surface 725d, and the slope of the first pressure plate inclined surface 725d can be consistent with the slope of the first switch inclined surface 723h described above, and when the first pressure plate 725 is assembled with the switch 723, the first pressure plate inclined surface 725d and the first switch inclined surface 723h can be parallel. The end of the pressure plate fitting portion 725c facing away from the substrate 725a can approximately form a sharp angle, and the top of the sharp angle can form a first limiting groove 725e. The distance from the lowest point of the bottom surface of the first limiting groove 725e to the substrate 725a is h1. As shown Figure 16As shown, in the thickness direction of the substrate 725a, the first limiting groove 725e and the receiving groove 725f can be aligned, and a part of the orthographic projection of the first limiting groove 725e on the substrate 725a can fall within the orthographic projection of the receiving groove 725f on the substrate 725a.

[0180] like Figure 17 As shown, the structure of the second pressing plate 726 is similar to that of the first pressing plate 725. For example, the second pressing plate 726 may include a base plate 726a and a pressing plate matching portion 726c. A side surface of the base plate 726a may also be designed with a receiving groove ( Figure 17 (Not shown). The pressure plate mating portion 726c has a second pressure plate inclined surface 726d. The slope of the second pressure plate inclined surface 726d can be consistent with the slope of the second switch inclined surface 723f described above. When the second pressure plate 726 is assembled with the switch 723, the second pressure plate inclined surface 726d and the second switch inclined surface 723f can be parallel. The end of the pressure plate mating portion 726c facing away from the substrate 726a can form a nearly sharp angle, and the top of this angle can form a second limiting groove 726e. The distance between the lowest point of the bottom surface of the second limiting groove 726e and the substrate 725a is h2.

[0181] Combine Figure 15 and Figure 17 As shown, unlike the first pressing plate 725, the second pressing plate 726 lacks a receiving portion. The distance h2 in the second pressing plate 726 can be smaller than the distance h1 in the first pressing plate 725. The smaller distance h2 allows the second pressing plate 726 to move within the shallower second receiving groove 71c; the larger distance h1 allows the first pressing plate 725 to move within the deeper first receiving groove 71e (described below). In other embodiments, the waterproof assembly may include only the first pressing plate 725 without the second pressing plate 726.

[0182] refer to Figure 10 As shown, the sealing member 727 can be a rotating body. The sealing member 727 can be made of a sealing material that is easy to undergo elastic deformation, such as rubber, silicone, etc. There can be two sealing members 727, combined Figure 10 and Figure 16 As shown, one sealing member 727 can be fixed in the receiving groove 725f of the first pressing plate 725, and another sealing member 727 can be fixed in the receiving groove of the second pressing plate 726. In other embodiments, when there is only one pressing plate, only one sealing member can be provided.

[0183] Combine Figure 10 and Figure 16 As shown, the magnet 728 can be fixed in the receiving portion 725b of the first pressing plate 725. In other embodiments, the magnet can also be fixed to the side of the base plate 726a of the second pressing plate 726 facing away from the pressing plate matching portion 726c.

[0184] like Figure 10 As shown, the elastic member 724 can be a spring. There can be two elastic members 724. In other embodiments, other components that can provide elastic force can also be used to replace the spring. When there is only one pressing plate, only one elastic member can also be provided.

[0185] Figure 18 for Figure 1 FIG. 7 is a schematic diagram of the HH cross-sectional structure of the electronic device 70. FIG. Figure 19 yes Figure 18 The partially enlarged structural diagram at G in the middle can represent the assembly structure of the waterproof component 72 and the housing 71. This will be described in detail below.

[0186] like Figure 19 As shown, a first waterproof breathable membrane 77 and a second waterproof breathable membrane 79 can be installed within the housing space 71a of the housing 71. The first waterproof breathable membrane 77 can, for example, cover one end of the housing through hole 71j, and the second waterproof breathable membrane 79 can, for example, cover one end of the housing through hole 71i. Both the first waterproof breathable membrane 77 and the second waterproof breathable membrane 79 are breathable and have a certain degree of waterproof performance (preventing liquid penetration and preventing liquid from passing through).

[0187] like Figure 19 As shown, a microphone 78 can also be installed in the housing space 71a of the housing 71. Microphone 78 can correspond to the housing through-hole 71i. Sound entering the housing space 71a through this second passage can pass through the second waterproof breathable membrane 79 and be picked up by microphone 78. The second receiving groove 71c has a relatively small depth, which can meet the design requirements of the sound cavity of microphone 78.

[0188] In this embodiment, the interior space of the electronic device 70 can also be equipped with a speaker and a controller ( Figure 19 The specific positions of the speaker and the controller can be designed as needed. A sound outlet can be provided on the housing 71 or the housing 73, and the sound emitted by the speaker can be transmitted from the sound outlet to the outside of the electronic device 70. The housing through hole 71j can be used as an air pressure balance hole for the speaker to balance the air pressure inside and outside the sound cavity of the speaker. Figure 19 As shown, the first receiving groove 71e has a large depth, which can meet the air pressure balance requirement of the speaker. The controller can be a central processing unit or a microcontroller unit (MCU).

[0189] In other embodiments, the functions of the housing through-hole 71j and / or the housing through-hole 71i are not limited to those described above. For example, a second microphone may be installed in the housing space 71a, corresponding to the housing through-hole 71j. Sound entering the housing space 71a through the first passage can pass through the first waterproof breathable membrane 77 and be picked up by the second microphone.

[0190] like Figure 19 As shown, a magnetic field sensor 75 can also be installed in the housing space 71a of the housing 71. The magnetic field sensor 75 is used to sense the magnetic flux of the magnet 728 and generate a detection signal. The magnetic flux of the magnet 728 detected by the magnetic field sensor 75 is proportional to the distance between the magnetic field sensor 75 and the magnet 728. The magnetic field sensor 75 can be a Hall effect sensor or a magnetometer. The Hall effect sensor can sense changes in magnetic flux. When the Hall effect sensor detects that the magnetic flux exceeds the hardware threshold of the Hall effect sensor, it can generate a corresponding detection signal and report it to the controller of the electronic device 70. The controller can process the detection signal sent by the Hall effect sensor. Unlike the Hall effect sensor, the magnetometer can detect the magnitude of the magnetic flux and send a detection signal to the controller. The controller can determine whether the magnetic flux exceeds the built-in software threshold based on the detection signal sent by the magnetometer and perform corresponding processing based on the determination result. The detection design related to the magnetic field sensor 75 will be further described below.

[0191] Combine Figure 19 、 Figure 11 and Figure 6 As shown, the bracket 722 can be mounted on the housing 71, for example, fixed to the housing 71 via a connector 721. The bracket 722 can surround the protrusions 71b, 71d, and 71f on the housing 71. An assembly gap is formed between the bracket 722 and the top surface of each protrusion, for example Figure 19 From the perspective, the top area of ​​the inner surface of the bracket 722 forms an assembly gap with the top surface of the protrusion 71f and the top surface of the protrusion 71b. In addition, one opening 722a of the bracket 722 is connected to the gap 71h on the shell 71, and the other opening 722a of the bracket 722 is connected to the gap 71g on the shell 71 (due to the Figure 19 Due to viewing angle, the openings and spacing are not shown).

[0192] like Figure 19 As shown, the switch 723 is carried on the protrusion 71f, the protrusion 71d and the protrusion 71b. The two sliding parts 723a at both ends of the switch 723 can be located in the assembly gap, and the sliding parts 723a can slide along the top surface of the protrusion 71f, the top surface of the protrusion 71d and the top surface of the protrusion 71b. Figure 19 In the illustrated state, the sliding portion 723a may be located at the right limit position. The force-applying portion 723d of the switch 723 may be exposed from the opening 722b of the bracket 722. The force-applying portion 723d may be provided for a user to apply force, and when the user pushes or pulls the force-applying portion 723d, the switch 723 may slide.

[0193] Combine Figure 15 and Figure 19As shown, the pressure plate matching portion 725c of the first pressure plate 725 can be received in the first receiving space 723b of the switch 723. Figure 19 、 Figure 15 and Figure 14 As shown, the first pressing plate inclined surface 725d of the pressing plate matching portion 725c contacts and is parallel to the first switch inclined surface 723h of the switch 723, and the bottom of the first pressing plate inclined surface 725d (the end away from the first limiting groove 725e) contacts the first protrusion 723g.

[0194] Combine Figure 15 and Figure 19 As shown, the base plate 725a of the first pressure plate 725 can be located in the first receiving groove 71e, and the base plate 725a can contact the switch 723. The magnet 728 on the base plate 725a is located in the first receiving groove 71e. The magnet 728 can be aligned with the position of the magnetic field sensor 75 so that the magnetic field sensor 75 detects the magnetic flux of the magnet 728.

[0195] like Figure 19 As shown, the left-side sealing member 727 can be fixed to the pressure plate mating portion 725c, with the head of the sealing member 727 positioned in the first receiving groove 71e. The sealing member 727 can be aligned with the housing through-hole 71j and spaced apart from the housing through-hole 71j. The left-side elastic member 724 can abut against the base plate 725a at one end and against the bottom wall of the first receiving groove 71e at the other end. The elastic member 724 can surround the outer circumference of the sealing member 727. Due to the elastic force of the elastic member 724, the base plate 725a can maintain contact with the switch 723.

[0196] Similarly, combined Figure 17 and Figure 19 As shown, the pressing plate matching portion 726c of the second pressing plate 726 can be received in the second receiving space 723c of the switch 723. Figure 19 、 Figure 17 and Figure 14 As shown, the second pressing plate inclined surface 726d of the pressing plate matching portion 726c contacts and is parallel to the second switch inclined surface 723f of the switch 723, and the bottom of the second pressing plate inclined surface 726d (the end away from the second limiting groove 726e) contacts the second protrusion 723e.

[0197] Combine Figure 17 and Figure 19 As shown, the base plate 726 a of the second pressing plate 726 may be located in the second receiving groove 71 c , and the base plate 726 a may contact the switch 723 .

[0198] like Figure 19As shown, the right-side seal 727 can be fixed to the pressure plate mating portion 726c, with the head of the seal 727 positioned in the second receiving groove 71c. The seal 727 can be aligned with and spaced apart from the housing through-hole 71i. One end of the right-side elastic member 724 can abut against the base plate 726a, while the other end can abut against the bottom wall of the second receiving groove 71c. The elastic member 724 can surround the outer circumference of the seal 727. Due to the elastic force of the elastic member 724, the base plate 726a can maintain contact with the switch 723.

[0199] Figure 4 Shown with Figure 19 The state of the waterproof assembly 72 shown is consistent, and this state can be called a connected state. In the connected state, combined with Figure 4 and Figure 19 As shown, one opening 722a, the gap 71g, the first receiving groove 71e, the housing through-hole 71j, and the housing space 71a are in communication. That is, the first channel formed by the other opening 722a, the gap 71g, the first receiving groove 71e, and the housing through-hole 71j is in communication, and this first channel connects the exterior of the housing 71 with the housing space 71a. Similarly, the second channel formed by the other opening 722a, the gap 71h, the second receiving groove 71c, and the housing through-hole 71i is in communication, and this second channel connects the exterior of the housing 71 with the housing space 71a.

[0200] Thus, the sound from outside the electronic device 70 can enter the inside of the electronic device 70 from the second channel and be picked up by the microphone 78. External air can also enter the inside of the electronic device 70 through the first channel to ensure the balance of internal and external air pressure of the electronic device 70. Due to the presence of the first waterproof breathable membrane 77 and the second waterproof breathable membrane 79, external liquid cannot enter the inside of the electronic device 70, thereby achieving breathability and waterproofness of the electronic device 70 in daily scenarios. In one embodiment, the first channel can serve as an air pressure balance channel for the electronic device, and a microphone is provided in the internal space of the shell corresponding to the second channel, so that the second channel constitutes the sound pickup channel of the electronic device. At this time, when the waterproof component 72 is in a connected state, the gas inside the shell can be exchanged with the external gas through the waterproof breathable membrane to achieve the purpose of balancing the internal and external air pressure and audio transmission.

[0201] refer to Figure 19 、 Figure 14 and Figure 15As shown, when the user pushes the force-applying portion 723d to the left, the sliding portion 723a will slide to the left. At this time, the first switch inclined surface 723h will apply pressure to the first pressure plate inclined surface 725d, causing the elastic force of the left elastic member 724 on the base plate 725a to increase. Under the combined action of this pressure and this elastic force, the first pressure plate 725 moves downward, and at the same time, the first pressure plate inclined surface 725d and the first switch inclined surface 723h slide relative to each other, and the sealing member 727 gradually approaches the housing through hole 71j. Similarly, referring to Figure 19 、 Figure 14 and Figure 17 As shown, the second switch slope 723f applies pressure to the second pressure plate slope 726d, increasing the elastic force of the right elastic member 724 on the base plate 726a. Under the combined action of this pressure and elastic force, the second pressure plate 726 moves downward, while the second pressure plate slope 726d and the second switch slope 723f slide relative to each other, and the sealing member 727 gradually approaches the housing through hole 71i.

[0202] Figure 20 It indicates that the two sealing members 727 are respectively pressed against the openings of the shell through hole 71j and the shell through hole 71i, and the shell through hole 71j and the shell through hole 71i are blocked. At this time, the waterproof component 72 can be said to be in a disconnected state.

[0203] Combine Figure 20 、 Figure 14 and Figure 15 As shown, in the disconnected state, the sliding portion 723a will slide to the left limit position, and the first protrusion 723g will enter the first limiting groove 725e and engage with the first limiting groove 725e. In addition, the first protrusion 723g can be basically located directly above the left sealing member 727, that is, the switch 723 can squeeze the first pressure plate 725 directly above the left sealing member 727, so that the left sealing member 727 can be reliably pressed against the opening of the shell through hole 71j, so that the left sealing member 727 will not tilt and affect the sealing effect. Similarly, in combination with Figure 20 、 Figure 14 and Figure 17 As shown, the second protrusion 723e enters the second limiting groove 726e and engages with the second limiting groove 726e. Similarly, the second protrusion 723e can be substantially located directly above the right sealing member 727. That is, the switch 723 can press the second pressing plate 726 directly above the right sealing member 727. This allows the right sealing member 727 to be reliably pressed against the opening of the housing through hole 71i, preventing the right sealing member 727 from tilting and affecting the sealing effect.

[0204] As a result, the switch 723 is locked in the left limit position, and the first pressing plate 725 and the second pressing plate 726 are locked in corresponding positions, thereby maintaining the waterproof component 72 in the disconnected state.

[0205] In the disconnected state, both the first and second channels are blocked, and the exterior of the housing 71 is disconnected from the housing space 71a, preventing external liquid from entering the interior of the electronic device 70. Since the seal 727 has a stable and reliable sealing performance, even if external liquid has a high pressure, it is difficult or impossible to enter the interior of the electronic device 70.

[0206] To use electronic device 70 in a high-pressure environment, the user can first deactivate switch 723 on electronic device 70, disabling waterproof assembly 72, and then carry electronic device 70 into the high-pressure environment. Because waterproof assembly 72 has already blocked the high-pressure liquid, first waterproof breathable membrane 77 and second waterproof breathable membrane 79 are not subject to high pressure and are therefore less susceptible to damage. Therefore, electronic device 70 can operate reliably in high-pressure environments.

[0207] To sum up, by pushing the switch 723, the waterproof component 72 is switched between the connected state and the disconnected state, which can not only make the electronic device 70 breathable and waterproof in daily scenarios, but also enable the electronic device 70 to work safely and reliably in a high water pressure environment.

[0208] Combine Figure 19 and Figure 20 It can be seen that in the process of switching from the connected state to the disconnected state: the movement stroke of the second pressure plate 726 is approximately equal to the distance h2 in the second pressure plate 726. Since the distance h2 is small, the movement stroke of the second pressure plate 726 can adapt to the shallower second receiving groove 71c; the movement stroke of the first pressure plate 725 is approximately equal to the distance h1 in the first pressure plate 725. Since the distance h1 is large, the movement stroke of the first pressure plate 725 can adapt to the deeper first receiving groove 71e.

[0209] Combine Figure 19 and Figure 20 As shown, during the process of switching the waterproof component 72 from the connected state to the disconnected state, the distance between the magnet 728 and the magnetic field sensor 75 gradually decreases, and the magnetic flux around the magnetic field sensor 75 gradually increases. When the waterproof component 72 is in the disconnected state, the magnetic flux around the magnetic field sensor 75 reaches a maximum value, and the magnetic field sensor 75 can generate a first detection signal. Conversely, during the process of switching the waterproof component 72 from the disconnected state to the connected state, the distance between the magnet 728 and the magnetic field sensor 75 gradually increases, and the magnetic flux around the magnetic field sensor 75 gradually decreases. When the waterproof component 72 is in the connected state, the magnetic flux around the magnetic field sensor 75 reaches a minimum value, and the magnetic field sensor 75 can generate a second detection signal.

[0210] In this embodiment, the state of the waterproof component 72 can be determined by the detection signal of the magnetic field sensor 75.

[0211] When the magnetic field sensor 75 generates a first detection signal, the controller of the electronic device 70 determines that the waterproof component 72 is in the disconnected state based on the first detection signal. When the magnetic field sensor 75 is a Hall sensor, the Hall sensor may generate the first detection signal when the magnetic flux is greater than or equal to a first threshold. The first threshold may be determined based on actual conditions, for example, the first threshold may be the maximum value. The first detection signal may be, for example, a low-level signal. Alternatively, when the magnetic field sensor 75 is a magnetometer, the magnetometer may generate the first detection signal to report the detected magnetic flux to the controller.

[0212] When the magnetic field sensor 75 generates a second detection signal, the controller of the electronic device 70 determines that the waterproof component 72 is in a connected state based on the second detection signal. Specifically, when the magnetic field sensor 75 is a Hall sensor, the Hall sensor may generate the second detection signal when the magnetic flux is less than or equal to a second threshold. The second threshold may be determined based on actual conditions; for example, the second threshold may be the minimum value. The second detection signal may be, for example, a high-level signal. Alternatively, when the magnetic field sensor 75 is a magnetometer, the magnetometer may generate the second detection signal to report the detected magnetic flux to the controller.

[0213] In this embodiment, after the controller determines the status of the waterproof component 72, the controller can control the relevant functional modules in the electronic device 70 to generate prompt information, and the prompt information is used to inform the user of the current status of the waterproof component 72 (that is, the current status of the electronic device 70). The form of the prompt information includes but is not limited to at least one of images, characters, audio, light, vibration, etc. For example, the controller can control the display screen to display images and / or characters, or control the speaker to output audio, or control the indicator light to emit light, or control the motor to generate vibration, etc. The specific content of the prompt information can be designed as needed. The design of detecting the status of the waterproof component 72 and sending prompt information enables the user to know the status of the electronic device 70, ensures that the user operates the electronic device 70 correctly according to the usage scenario, and enhances the user experience.

[0214] Different from the above solution, in other embodiments, the state of the waterproof component 72 can be determined by a microphone and a speaker, as will be explained below.

[0215] Figure 21 A schematic diagram illustrating a principle for determining the status of the waterproof component 72 in other embodiments is shown. Figure 21 The microphone in can be microphone 78. Figure 21 The speaker in the figure can be the above-mentioned speaker, or can be replaced by a buzzer (both the buzzer and the speaker can be referred to as sound-generating devices). Figure 21The depth gauge is used to measure the depth of the electronic device 70 under water. Figure 21 As shown, the principle of determining the status of the waterproof component 72 is as follows:

[0216] The controller can control the speaker to output a set sound signal (e.g., a sound signal of a specific frequency), which can be transmitted to the outside of the electronic device and may be picked up by the microphone. When the waterproof component 72 is in the disconnected state, the sound signal cannot enter the interior of the electronic device through the first channel or the second channel, and thus the microphone cannot pick up the sound signal. When the controller determines that the microphone has not picked up the sound signal, the controller determines that the waterproof component 72 is in the disconnected state. Conversely, when the waterproof component 72 is in the non-disconnected state (including the connected state, and the intermediate state between the connected state and the disconnected state. The waterproof component 72 is in the intermediate state when the first channel or the second channel is not completely blocked), the sound signal can enter the interior of the electronic device through the first channel or the second channel and be picked up by the microphone. When the controller determines that the microphone has picked up the sound signal and the intensity of the sound signal is large, the controller determines that the waterproof component 72 is in the connected state; when the controller determines that the microphone has picked up the sound signal and the intensity of the sound signal is small, the controller determines that the waterproof component 72 is in the intermediate state.

[0217] Before the electronic device enters a high-pressure water environment, the user can manually switch the waterproof component 72 to the disconnected state, at which point the electronic device will automatically complete the status check of the waterproof component 72. Alternatively, the user can manually trigger the status check of the waterproof component 72 through the user interface of the electronic device. When the electronic device indicates that the waterproof component 72 is disconnected, the user can carry the electronic device into the high-pressure water environment. Optionally, the user interface of the electronic device can prompt the user to manually switch the waterproof component 72 to the disconnected state. For example, in the case of a smartwatch, if the user selects "Swimming" or "Diving" on the user interface of the smartwatch, a prompt window will automatically pop up on the watch, displaying the message "Please turn on the switch on the side of the watch." Alternatively, if the user did not switch the waterproof component 72 to the connected state (i.e., did not turn off the switch on the side of the watch) after swimming or diving last time, and the waterproof switch on the watch is already on, and the user selects "Swimming" or "Diving" on the user interface of the smartwatch, the watch can detect that the waterproof component 72 is disconnected by emitting audio from the speaker, which is picked up by the microphone, or by magnetic field detection. Alternatively, a prompt window may automatically pop up, displaying the message "The waterproof switch on the side of the watch is on."

[0218] When an electronic device enters a high water pressure environment, the state of the waterproof component 72 may change due to high pressure or other abnormalities, which may cause liquid to enter the electronic device. In order to promptly remind the user of this risk and avoid damage to the electronic device due to liquid, the electronic device can perform a state detection of the waterproof component 72 again. Schematically, the depth of the electronic device under water can be detected by a depth gauge, and the detection result of the depth gauge can be used as a trigger condition for the state detection. For example, when the controller determines that the depth detected by the depth gauge is a first depth (for example, 0.5m), the controller can start the state detection. When the controller determines that the depth detected by the depth gauge is a second depth (for example, 5m), the controller can start the state detection again. It is easy to understand that the state detection based on the depth information can be triggered only once or several times. The specific number of detections is designed according to needs and is not limited to the above.

[0219] In other embodiments, the depth gauge may not be used to trigger the status detection, and the status detection may be triggered according to other pre-configured trigger conditions, for example, the status detection may be triggered at a fixed time.

[0220] In other embodiments, the above-mentioned magnetic field detection method and the microphone and speaker detection method can be combined to comprehensively determine the state of the waterproof component 72. Alternatively, in other embodiments, the state of the waterproof component 72 can be detected.

[0221] Example 2

[0222] Figure 22 A schematic diagram showing a partial assembly structure of the waterproof component 82 and the housing 81 in the electronic device of the second embodiment is shown. Figure 23 for Figure 22 The decomposition diagram of the structure shown in Figure 1 is as follows. Figure 22 and Figure 23 As shown, the waterproof component 82 can be installed on the housing 81.

[0223] like Figure 24 and Figure 25 As shown, the housing 81 has a housing space 81a, which is the internal space of the electronic device of Example 2. The housing 81 is formed with a receiving groove 81b, a vent groove 81g, and a vent groove 81h. The vent grooves 81g and 81h are both formed on the surface where the opening of the receiving groove 81b is located, and the vent grooves 81g and 81h are both connected to the receiving groove 81b. The vent grooves 81g and 81h can also be called vents.

[0224] like Figure 25 As shown, the bottom wall of the receiving groove 81b can be provided with a shell through hole 81j and a shell through hole 81i, and the shell through hole 81j and the shell through hole 81i are both connected to the receiving groove 81b and the shell space 81a. Figure 25As shown, schematically, the outer peripheries of the housing through-holes 81j and 81i can form an annular groove structure, which is used to mount an elastic member (described below) in the waterproof assembly 82. In other embodiments, the outer peripheries of the housing through-holes 81j and 81i can also be flat surfaces, eliminating the need for the annular groove structure.

[0225] Will Figure 24-25 and Figure 6-Figure 7 By comparison, it can be seen that the structure of housing 81 is similar to that of housing 71, the main difference being that housing 81 does not have a boss. The above-mentioned internal and external structure of housing 81 is merely illustrative, and the embodiments of the present application are not limited thereto. For example, the housing in other embodiments may have only one vent groove and one housing through hole.

[0226] like Figure 26 As shown, the waterproof assembly 82 may include a bracket 822, a connector 821, a switch 823, a pressure plate 825, a seal 827, a magnet 828, a first elastic member 824, a loading frame 826, a limiting column 829, and a limiting column elastic member 830. Each of these will be described below.

[0227] contrast Figure 26 and Figure 11 As shown, the structure of the bracket 822 is similar to that of the bracket 722 described above. The bracket 822 can also be a substantially strip-shaped cover-like structure, having an inner cavity and an opening 822b, wherein the opening 822b connects the inner cavity with the exterior of the bracket 822. Two openings 822a can be provided on a wall (e.g., a side wall) on one side of the bracket 822, wherein the openings 822a connect the inner cavity with the exterior of the bracket 822.

[0228] Combine Figure 22-Figure 25 As shown, when the waterproof assembly 82 is installed to the housing 81, the bracket 822 is fixedly connected to the housing 81. For example, the bracket 822 can be fixedly connected to the housing 81 via a connector 821 (e.g., a threaded connector). The two openings 822a of the bracket 822 are respectively connected to the vent groove 81g and the vent groove 81h of the housing 81. Therefore, one opening 822a, the vent groove 81g, the receiving groove 81b, the housing through hole 81j and the housing space 81a are connected in sequence, that is, one opening 822a, the vent groove 81g, the receiving groove 81b and the housing through hole 81j form a first channel, which connects the outside of the housing 81 with the housing space 81a. Another opening 822a, the vent groove 81h, the receiving groove 81b, the shell through hole 81i and the shell space 81a are connected, that is, another opening 822a, the vent groove 81h, the receiving groove 81b and the shell through hole 81i form a second channel, which connects the outside of the shell 81 with the shell space 81a.

[0229] like Figure 27 、 Figure 28 and Figure 29 As shown, the switch 823 can be roughly a strip-shaped cover-like structure. The switch 823 can include a sliding portion 823a and a force-applying portion 823d. The sliding portion 823a can be flat, and there can be two sliding portions 823a, and the two sliding portions 823a can be basically located in the same plane. The force-applying portion 823d can be connected between the two sliding portions 823a and protrude relative to the sliding portions 823a. A local area of ​​the force-applying portion 823d is concave to form a first receiving space 823b and a second receiving space 823c, and the first receiving space 823b and the second receiving space 823c are spaced apart. The first receiving space 823b and the second receiving space 823c can be of the same size.

[0230] like Figure 29 As shown, the inner surface of the first receiving space 823b includes a first switch slope 823h, and the inner surface of the second receiving space 823c includes a second switch slope 823f. The second switch slope 823f may be parallel to the first switch slope 823h.

[0231] like Figure 29 As shown, a limiting groove 823j can also be formed on the sliding portion 823a. The limiting groove 823j can be located on the side of the first receiving space 823b away from the second receiving space 823c, and the opening of the limiting groove 823j is in the same direction as the opening of the first receiving space 823b.

[0232] contrast Figure 27-Figure 29 ,as well as Figure 13-14 As shown, the structure of switch 823 is similar to that of switch 723 described above, except that switch 823 lacks the first and second protrusions and instead has a retaining groove 823j. The above internal and external structures of switch 823 are merely illustrative, and embodiments of the present application are not limited thereto. For example, in other embodiments, the switch may have only one receiving space.

[0233] like Figure 30 and Figure 31 As shown, the pressure plate 825 may include a substrate 825a, a receiving portion 825f, a pressure plate matching portion 825b and a pressure plate matching portion 825c. The substrate 825a may be roughly flat. Two receiving grooves 825g may be provided on one side surface of the substrate 825a (the normal of the surface may be along the thickness direction of the substrate 825a). The receiving portion 825f may be located on the same side of the substrate 825a as the receiving groove 825g. The pressure plate matching portion 825b and the pressure plate matching portion 825c may be connected to the other side of the substrate 825a, with a gap between the pressure plate matching portion 825b and the pressure plate matching portion 825c.

[0234] like Figure 30As shown, the outer shapes of the pressure plate mating portion 825b and the pressure plate mating portion 825c can be substantially identical, and both can be roughly prismatic structures with a trapezoidal cross-section. The pressure plate mating portion 825b has a first pressure plate inclined surface 825e. The slope of the first pressure plate inclined surface 825e can be consistent with the slope of the first switch inclined surface 823h described above. When the pressure plate 825 is assembled with the switch 823, the first pressure plate inclined surface 825e and the first switch inclined surface 823h can be parallel. The pressure plate mating portion 825c has a second pressure plate inclined surface 825d. The slope of the second pressure plate inclined surface 825d can be consistent with the slope of the second switch inclined surface 823f described above. When the pressure plate 825 is assembled with the switch 823, the second pressure plate inclined surface 825d and the second switch inclined surface 823f can be parallel.

[0235] contrast Figure 30-Figure 31 ,as well as Figure 15-17 As shown, the structure of the pressing plate 825 is similar to the first pressing plate 725 and the second pressing plate 726 described above, except that the pressing plate 825 is equivalent to combining the first pressing plate 725 and the second pressing plate 726 into one. The movement stability of the single pressing plate 825 is better.

[0236] Different from the second embodiment, in other embodiments, the pressing plate may include only one matching portion.

[0237] refer to Figure 26 As shown, the seal 827 can be a rotating body. The seal 827 can be made of a sealing material that is easy to elastically deform, such as rubber, silicone, etc. There can be two seals 827, combined Figure 26 and Figure 31 As shown, one sealing member 827 can be fixed in one receiving groove 825g of the pressing plate 825, and another sealing member 827 can be fixed in another receiving groove 825g. In other embodiments, when the pressing plate has only one matching portion, only one sealing member can be provided.

[0238] Combine Figure 26 and Figure 31 As shown, the magnet 828 can be fixed in the receiving portion 825f of the pressure plate 825.

[0239] like Figure 26 As shown, the first elastic member 824 can be a spring. There can be two first elastic members 824. In other embodiments, other components that can provide elastic force can also be used to replace the spring. When the pressure plate has only one mating portion, only one first elastic member can also be provided.

[0240] like Figure 32 and Figure 33As shown, the loading rack 826 can be roughly a frame structure, and its specific structure can be designed according to product requirements. The loading rack 826 can have a receiving groove 826c, and the bottom wall 826d of the receiving groove 826c can have a receiving through hole 826a, which is connected to the receiving groove 826c. The loading rack 826 can also have a hollow area 826b, which can be considered as a space formed by removing material.

[0241] like Figure 34 As shown, the limiting column 829 may include a column 829a and a limiting skirt 829b surrounding the outer circumference of the column 829a. The column 829a may be a substantially cylindrical structure, one end of which may be substantially spherical.

[0242] like Figure 26 As shown, the limiting column elastic member 830 can be a spring. In other embodiments, other components that can provide elastic force can also be used to replace the spring.

[0243] Figure 35 for Figure 22 AA cross-sectional structural diagram of the structure of the electronic device shown in FIG, Figure 35 It can represent the assembly structure of the waterproof component 82 and the housing 81. It will be described in detail below.

[0244] like Figure 35 As shown, a first waterproof breathable membrane 87 and a second waterproof breathable membrane 89 can be installed within the housing space 81a of the housing 81. The first waterproof breathable membrane 87 can, for example, cover one end of the housing through hole 81j, and the second waterproof breathable membrane 89 can, for example, cover one end of the housing through hole 81i. Both the first waterproof breathable membrane 87 and the second waterproof breathable membrane 89 are breathable and have a certain degree of waterproof performance (preventing liquid penetration and preventing liquid from passing through).

[0245] like Figure 35 As shown, a microphone 88 may be installed in the housing space 81a of the housing 81. The microphone 88 may correspond to the housing through hole 81i, and the sound entering the housing space 81a through the second channel may pass through the second waterproof breathable membrane 89 and be picked up by the microphone 88.

[0246] In this embodiment, the interior space of the electronic device can also be equipped with a speaker and a controller ( Figure 35 (Not shown). The specific locations of the speaker and controller can be designed as needed. The sound emitted by the speaker can be transmitted outside the electronic device. The housing through hole 81j can serve as an air pressure balance hole for the speaker. The controller can be a central processing unit or a microcontroller unit (MCU).

[0247] In other embodiments, the functions of the housing through-hole 81j and / or the housing through-hole 81i are not limited to those described above. For example, a second microphone may be installed in the housing space 81a, corresponding to the housing through-hole 81j. Sound entering the housing space 81a through the first passage can pass through the first waterproof breathable membrane 88 and be picked up by the second microphone.

[0248] like Figure 35 As shown, a magnetic field sensor 85 can also be installed in the housing space 81a of the housing 81. The magnetic field sensor 85 is used to sense the magnetic flux of the magnet 828 and generate a detection signal. The type and operating principle of the magnetic field sensor 85 can be the same as the magnetic field sensor 75 described above and will not be repeated here.

[0249] Combine Figure 35 、 Figure 32 and Figure 24 As shown, the loading rack 826 can be mounted to the housing 81, and the hollow area 826b of the loading rack 826 corresponds to and communicates with the receiving groove 81b of the housing 81. In other embodiments, the waterproof assembly may not include the loading rack 826, and the loading rack 826 may be included as part of the housing of the electronic device.

[0250] like Figure 35 As shown, the limiting column 829 can be installed in the receiving groove 826c of the loading frame 826. Figure 35 and Figure 32 As shown, the column 829a of the limiting column 829 can extend from the receiving through hole 826a of the loading frame 826, and the limiting skirt 829b of the limiting column 829 can contact the bottom wall 826d of the receiving groove 826c. The limiting column elastic member 830 can be located in the receiving groove 826c. One end of the limiting column elastic member 830 can abut the housing 81, and the other end can abut the limiting skirt 829b. The elastic force of the limiting column elastic member 830 toward the limiting skirt 829b can keep the limiting skirt 829b in contact with the bottom wall 826d of the receiving groove 826c, thereby exposing the end of the column 829a to the loading frame 826.

[0251] like Figure 35 As shown, the bracket 822 can be fixed to the housing 81 by a connector 821. The bracket 822 surrounds the loading frame 826 and forms an assembly gap with the loading frame 826. Figure 35 and Figure 32 As shown, the opening 822 b of the bracket 822 can be substantially aligned with the hollow area 826 b of the loading rack 826 , and the receiving groove 826 c of the loading rack 826 can be covered by the bracket 822 .

[0252] like Figure 35As shown, the switch 823 is carried on the loading frame 826, and the two sliding parts 823a at both ends of the switch 823 can be located in the assembly gap, and the sliding parts 823a can slide along the top surface of the loading frame 826. Figure 35 In the illustrated state, the sliding portion 823a may be located at the right limit position. The force-applying portion 823d of the switch 823 may be exposed from the opening 822b of the bracket 822. The force-applying portion 823d may be provided for a user to apply force, and when the user pushes or pulls the force-applying portion 823d, the switch 823 may slide.

[0253] Combine Figure 35 、 Figure 30 and Figure 29 As shown, the pressure plate engaging portion 825b of the pressure plate 825 can be accommodated in the first receiving space 823b of the switch 823. The first pressure plate inclined surface 825e of the pressure plate engaging portion 825b contacts and is parallel to the first switch inclined surface 823h of the switch 823, and the bottom of the first pressure plate inclined surface 825e (the end where the first pressure plate inclined surface 825e connects to the base plate 825a) contacts the top of the first switch inclined surface 823h (the end of the first switch inclined surface 823h located at the opening of the first receiving space 823b). Similarly, the pressure plate engaging portion 825c of the pressure plate 825 can be accommodated in the second receiving space 823c of the switch 823. The second pressure plate inclined surface 825d of the pressure plate matching portion 825c is in contact with and parallel to the second switch inclined surface 823f of the switch 823, and the bottom of the second pressure plate inclined surface 825d (the end where the second pressure plate inclined surface 825d is connected to the substrate 825a) is in contact with the top of the second switch inclined surface 823f (the end where the second switch inclined surface 823f is located at the opening of the second receiving space 823c).

[0254] Combine Figure 35 and Figure 29 As shown, the base plate 825a of the pressure plate 825 can be located in the receiving groove 81b, and the base plate 825a can contact the switch 823. The magnet 828 on the base plate 825a is located in the receiving groove 81b. The magnet 828 can be aligned with the position of the magnetic field sensor 85 so that the magnetic field sensor 85 detects the magnetic flux of the magnet 828.

[0255] like Figure 35As shown, two sealing members 827 can be fixed to the pressure plate mating portion 825b and the pressure plate mating portion 825c, respectively, and the heads of the two sealing members 827 can be located in the receiving groove 81b. One sealing member 827 can be aligned with the housing through hole 81j and maintain a distance therefrom, while the other sealing member 827 can be aligned with the housing through hole 81i and maintain a distance therefrom. One end of the two first elastic members 824 can both abut against the substrate 825a, and the other end can both abut against the bottom wall of the receiving groove 81b. One first elastic member 824 can surround the outer circumference of one sealing member 827, and the other first elastic member 824 can surround the outer circumference of the other sealing member 827. Due to the elastic support of the first elastic member 824, the substrate 825a can maintain contact with the switch 823.

[0256] Figure 22 and Figure 35 All the waterproof components in the shell are in a connected state, among which a first channel formed by an opening 822a, a vent groove 81g, a receiving groove 81b and a shell through hole 81j is in a connected state, and the first channel connects the outside of the shell 81 with the shell space 81a; a second channel formed by another opening 822a, a vent groove 81h, a receiving groove 81b and a shell through hole 81i is in a connected state, and the second channel connects the outside of the shell 81 with the shell space 81a.

[0257] Thus, sound from outside the electronic device can enter the electronic device through the second channel and be picked up by microphone 88. External air can also enter the electronic device through the first channel, ensuring balanced air pressure inside and outside the electronic device. Due to the presence of the first waterproof breathable membrane 87 and the second waterproof breathable membrane 89, external liquids cannot enter the electronic device, thus ensuring that the electronic device is breathable and waterproof in everyday use.

[0258] refer to Figure 35 As shown, when the user pushes the force application portion 823d to the left, the sliding portion 823a will slide to the left. Figure 29 and Figure 30 As shown, the first switch slope 823h applies pressure to the first pressure plate slope 825e, increasing the elastic force of the left elastic member 824 on the base plate 825a. The second switch slope 823f applies pressure to the second pressure plate slope 825d, increasing the elastic force of the right elastic member 824 on the base plate 825a. Under the combined action of these pressures and elastic forces, the pressure plate 825 moves downward, while the first pressure plate slope 825e slides relative to the first switch slope 823h, and the second pressure plate slope 825d slides relative to the second switch slope 823f. The left seal 827 gradually approaches the housing through-hole 81j, and the right seal 827 gradually approaches the housing through-hole 81i.

[0259] Figure 36 It indicates that the two sealing members 827 are respectively pressed against the opening of the shell through hole 81j and the opening of the shell through hole 81i, and the shell through hole 81j and the shell through hole 81i are blocked. At this time, the waterproof component 82 can be said to be in a disconnected state.

[0260] In this disconnected state, the combination Figure 36 、 Figure 30 and Figure 29 As shown, the top of the first switch slope 823h contacts the top of the first pressing plate slope 825e (the end of the first pressing plate slope 825e away from the bottom 825a), and the top of the second pressing plate slope 825d (the end of the second pressing plate slope 825d away from the bottom 825a) contacts the top of the second switch slope 823f. Figure 36 As shown, the switch 823 can squeeze the pressure plate 825 from directly above the two seals 827, so that the two seals 827 can be reliably pressed against the opening of the shell through hole 81j and the opening of the shell through hole 81i, so that the two seals 827 will not be lifted up and affect the sealing effect.

[0261] In this disconnected state, the combination Figure 36 、 Figure 29 and Figure 34 As shown, the sliding portion 823a will slide to the left limit position. Under the elastic support of the limiting column elastic member 830 on the limiting skirt 829b, the end of the column 829a will be stuck in the limiting groove 823j, so that the switch 823 is locked in the left limit position, thereby maintaining the waterproof component 82 in the disconnected state.

[0262] In the disconnected state, both the first and second channels are blocked, and the exterior of the housing 81 is disconnected from the housing space 81a, preventing external liquid from entering the interior of the electronic device 70. Since the seal 827 has a stable and reliable sealing performance, even if the external liquid has a high pressure, it is difficult or impossible to enter the interior of the electronic device.

[0263] To use an electronic device in a high-pressure environment, the user can first deactivate switch 823, disabling waterproof assembly 82, and then carry the electronic device into the high-pressure environment. Because waterproof assembly 82 has already blocked the high-pressure liquid, the first and second waterproof breathable membranes 87 and 89 are no longer subject to high pressure and are therefore less susceptible to damage. Consequently, the electronic device can operate reliably in high-pressure environments.

[0264] In summary, by pushing the switch 823, the waterproof component 82 is switched between the connected state and the disconnected state, which can not only make the electronic device breathable and waterproof in daily scenarios, but also enable the electronic device to work safely and reliably in a high water pressure environment.

[0265] Similar to the first embodiment, the second embodiment can also detect the status of the waterproof component 82 using the magnetic field sensor 85 and the magnet 828, and / or using a microphone and a speaker (a depth gauge can also be used), and send a prompt message based on the detection result of the status of the waterproof component 82. The specific principles are the same as those described above and will not be repeated here.

[0266] In other embodiments, the status of the waterproof component 82 may not be detected.

[0267] In other embodiments, several alternative designs may be made to the solution of the second embodiment according to product requirements.

[0268] In one embodiment, the pressure plate can connect the two seals, but only have one pressure plate mating portion. Accordingly, the switch can have only one receiving space and one switch inclined surface. The coordination between the switch and the pressure plate is similar to that described in Examples 1 and 2, with motion transmission achieved through the coordination of the inclined surfaces. That is, the direction of switch movement is substantially perpendicular to that of the pressure plate. Furthermore, when the switch is moved to the extreme position where the seal blocks the housing through-hole, the bracket can lock the switch. For example, the bracket and switch can be locked through the coordination of a protrusion and a groove.

[0269] In another embodiment, the switch and the pressure plate do not transmit motion via an inclined surface (the switch and the pressure plate move in perpendicular directions), and the switch and the pressure plate can move in the same direction. For example, the switch can be directly or indirectly connected to the pressure plate, the switch can move along the centerline of the housing through hole, and the pressure plate can move along the centerline of the housing through hole under the drive of the switch. In this embodiment, the pressure plate can be connected to at least one seal.

[0270] In another embodiment, the movement direction of the switch is perpendicular to the movement direction of the pressure plate, and the movement of the switch can be transmitted to the pressure plate through an intermediate piece. For example, an intermediate piece can be provided between the switch and the pressure plate, and the intermediate piece can include a connected shaft portion and a cam portion. The shaft portion can be provided with a curved sliding groove, and the switch can slide in cooperation with the sliding groove. The cam portion can be in sliding contact with the pressure plate, and the diameter of the cam portion is not uniform. The sliding contact of the portion with a smaller diameter with the pressure plate will move the pressure plate away from the through hole of the housing, and the sliding contact of the portion with a larger diameter with the pressure plate will move the pressure plate closer to the through hole of the housing. When the switch moves, due to the cooperation between the switch and the sliding groove, the switch can drive the shaft portion to rotate, so that the shaft portion drives the cam portion to rotate, thereby allowing the pressure plate to move closer to or away from the through hole of the housing. In this embodiment, the pressure plate can be connected to at least one sealing member.

[0271] Example 3

[0272] like Figure 37 and Figure 38As shown, the electronic device 10 of the third embodiment can be, for example, a smartwatch. The electronic device 10 can include a display 12, a housing 11 (e.g., a middle frame), a housing 14 (e.g., a rear housing), and a waterproof assembly 13. The display 12 and housing 14 are mounted on opposite sides of the housing 11. The display 12, housing 11, and housing 14 can enclose an inner cavity of the electronic device 10. The waterproof assembly 13 can be mounted on the housing 11.

[0273] like Figure 39 and Figure 40 As shown, the outer shape of the housing 11 can be, for example, approximately annular. The housing 11 defines a housing space 11b, which is part of the inner cavity of the electronic device 10. A groove 11a is defined in the housing 11, with the opening of the groove 11a located on the outer side of the housing 11. The groove 11a is used to mount the waterproof assembly 13.

[0274] like Figure 40 and Figure 41 As shown, the groove 11a on the housing 11 may be a stepped groove, and the groove 11a may include a first groove 11c and a second groove 11d, and the opening of the first groove 11c may be larger than the opening of the second groove 11d.

[0275] like Figure 41 As shown, the bottom surface 11e of the first groove 11c may be provided with a connecting hole 11g, which may be a blind hole. For example, there may be two connecting holes 11g, which are respectively located on both sides of the bottom surface 11e.

[0276] like Figure 41 As shown, the bottom surface 11f of the second groove 11d can define two housing through-holes 11h. Both housing through-holes 11h can be spaced apart from the side surfaces of the second groove 11d. Both housing through-holes 11h can penetrate the bottom wall of the second groove 11d and communicate with the housing space 11b of the housing 11. In other words, the groove 11a can communicate with the housing space 11b via the two housing through-holes 11h. The bottom surface 11f of the second groove 11d can also define a mounting groove 11i, which can be located between the two housing through-holes 11h.

[0277] like Figure 42 and Figure 43 As shown, the waterproof component 13 may include a bracket 132 , a pin 136 , a switch 133 , a connector 131 (eg, a screw), a pressure plate 137 , a seal 134 and an elastic member 135 .

[0278] like Figure 44As shown, the bracket 132 can be approximately a long strip frame structure. The bracket 132 can be provided with a connecting hole 132a, which is a through hole. For example, there can be two connecting holes 132a, and the two connecting holes 132a are respectively located at the two ends of the bracket 132. The connecting hole 132a is used to install the connector 131. The bracket 132 can also be provided with a bracket through hole 132d, and there can be two bracket through holes 132d, and the two bracket through holes 132d can be located between the two connecting holes 132a. The area between the two bracket through holes 132d on the bracket 132 can be hollowed out to form a receiving space 132b. A mounting hole 132c can be opened on the wall of the receiving space 132b. The mounting hole 132c is also located between the two bracket through holes 132d. The mounting hole 132c can be a circular hole or a non-circular hole.

[0279] like Figure 43 As shown, the outer shape of the pin 136 can be approximately cylindrical or rod-shaped. The main body of the pin 136 may not be cylindrical, and the cross section of the main body may have an irregular shape. Figure 43 and Figure 44 As shown, the pin shaft 136 can cooperate with the mounting hole 132 c on the bracket 132 , and this cooperation enables the pin shaft 136 to be fixed in the mounting hole 132 c.

[0280] like Figure 45 As shown, the switch 133 may include a sliding portion 133a, a force-applying portion 133b and a switch-matching portion 133c. The force-applying portion 133b and the switch-matching portion 133c may be located on both sides of the sliding portion 133a, respectively.

[0281] like Figure 45 As shown, the sliding portion 133a can be approximately shaped like a hollow block, with a sliding cavity 133d therein, which is configured to slidably engage with the pin 136. The force-applying portion 133b can be approximately shaped like a circular arch. The force-applying portion 133b is configured to allow the user to apply force, thereby enabling the user to toggle the switch 133. The end of the switch-matching portion 133c, distal from the sliding portion 133a, can be approximately V-shaped with a sharp angle to facilitate engagement with the pressure plate 137. This V-shaped angle of the switch-matching portion 133c can include a switch slope 133e.

[0282] like Figure 46 As shown, the pressure plate 137 may include a base plate 137a, a pressure plate fitting portion 137c, a seal mounting portion 137b, and an elastic member limiting portion 137d. The base plate 137a may be approximately in the shape of a long strip. The pressure plate fitting portion 137c may be protruding from one side of the base plate 137a (e.g., one side in the thickness direction), and the seal mounting portion 137b and the elastic member limiting portion 137d may be located on the other side of the base plate 137a (e.g., the other side in the thickness direction).

[0283] like Figure 46 As shown, the outer shape of the pressure plate matching portion 137c can be approximately herringbone-shaped. The pressure plate matching portion 137c can include two pressure plate inclined surfaces 137f, both of which are connected to the base plate 137a and can form an obtuse angle with the base plate 137a. Each pressure plate inclined surface 137f is connected to a side wall 137e on opposite sides, and the two side walls 137e and the pressure plate inclined surface 137f form a matching groove 137g. There can be two such matching grooves 137g. A limiting groove 137h can be provided on the top of the pressure plate matching portion 137c facing away from the base plate 137a, and the limiting groove 137h is also located between the two pressure plate inclined surfaces 137f (or between the two matching grooves 137g).

[0284] like Figure 46 As shown, the sealing member installation portion 137b and the elastic member limiting portion 137d can both be approximately cylindrical. There can be two sealing member installation portions 137b, and the elastic member limiting portion 137d is located between the two sealing member installation portions 137b.

[0285] Figure 46 The pressure plate 137 shown may be a symmetrical structure, and the symmetry plane may pass through the elastic member limiting portion 137d. The two matching grooves 137g are symmetrically distributed about the symmetry plane, and the two sealing member mounting portions 137b are also symmetrically distributed about the symmetry plane.

[0286] Figure 46 The structure of the pressing plate 137 shown is only a schematic diagram, and the present embodiment 3 is not limited thereto. Figure 46 As shown, other variations of the pressing plate can be designed. For example, the pressing plate can have two pressing plate inclined surfaces 137f but no mating groove 137g (i.e., no sidewall 137e); or, the pressing plate can have only one pressing plate inclined surface 137f and either have or no mating groove 137g.

[0287] like Figure 47 As shown, seal 134 may include a mounting portion 134a and a sealing portion 134c, which are connected to each other. Mounting portion 134a may be cylindrical and may include a mounting hole 134b therein, which may be a blind hole. Sealing portion 134c may be truncated cone-shaped, with the end distal to mounting portion 134a having a smaller diameter and the end connected to mounting portion 134a having a larger diameter. Seal 134 may be made of a resilient sealing material, such as rubber or silicone.

[0288] like Figure 43 As shown, the elastic member 135 may be, for example, a spring, or other elastically extendable member.

[0289] Figure 48 and Figure 49It can represent the assembly structure of the waterproof component 13, and an assembly state of the waterproof component 13 and the housing 11. Figure 49 yes Figure 48 Schematic diagram of the locally enlarged structure at point C in the middle.

[0290] The first waterproof breathable membrane and the second waterproof breathable membrane ( Figure 49 (Not shown), the first waterproof breathable membrane can, for example, cover one end of the left housing through hole 11h, and the second waterproof breathable membrane can, for example, cover one end of the right housing through hole 11h. Both the first and second waterproof breathable membranes are breathable and have a certain degree of waterproof performance (preventing liquid penetration and preventing liquid from passing through).

[0291] A microphone can also be installed in the housing space 11b ( Figure 49 (Not shown). The microphone may correspond to the housing through hole 11h on the right side, for example.

[0292] The electronic device 10 may also be provided with a speaker and a controller ( Figure 49 (Not shown). The specific locations of the speaker and controller can be designed as needed. The sound emitted by the speaker can be transmitted outside the electronic device 10. The housing through hole 11h on the left side can serve as an air pressure balance hole for the speaker. The controller can be a central processing unit or a microcontroller unit (MCU).

[0293] Combine Figure 46 、 Figure 41 and Figure 49 As shown, the base plate 137a, the sealing member mounting portion 137b and the elastic member limiting portion 137d of the pressure plate 137 can be located in the second groove 11d of the housing 11. One end of the elastic member 135 can be installed in the mounting groove 11i of the housing 11, and the other end of the elastic member 135 can be sleeved on the outer periphery of the elastic member limiting portion 137d and abut against the base plate 137a. The elastic member 135 is used to apply elastic force to the pressure plate 137. The seal 134 is fixedly connected to the seal mounting portion 137b. Combined Figure 47 and Figure 49 As shown, the mounting hole 134b on the mounting portion 134a of the seal 134 can cooperate with the seal mounting portion 137b, and the sealing portion 134c of the seal 134 faces the shell through hole 11h of the shell 11, and the sealing portion 134c is spaced apart from the shell through hole 11h.

[0294] Combine Figure 44 、 Figure 41 and Figure 49As shown, the bracket 132 can be installed in the first groove 11c of the shell 11. The two ends of the bracket 132 are supported on the bottom surface 11e of the first groove 11c, and the connecting hole 132a on the bracket 132 can be aligned with the connecting hole 11g on the bottom surface 11e. The connecting member 131 can cooperate with the connecting hole 132a and the connecting hole 11g to fix the bracket 132 to the shell 11. In addition, the bracket through hole 132d on the bracket 132 is connected to the second groove 11d. Under the elastic support of the elastic member 135, the base plate 137a can be abutted against the bracket 132. The pressure plate matching portion 137c of the pressure plate 137 can be located in the receiving space 132b of the bracket 132.

[0295] Combine Figure 45 、 Figure 41 and Figure 49 As shown, the pin 136 passes through the sliding cavity 133d of the switch 133 and the mounting hole 132c on the bracket 132 to mount the switch 133 on the bracket 132. The pin 136 forms a fixed connection with the mounting hole 132c on the bracket 132. The switch 133 is located in the mounting space 132b of the bracket 132, and the switch mating portion 133c of the switch 133 can be located at the junction of the pressure plate mating portion 137c and the base plate 137a (or at the root of the pressure plate mating portion 137c). Figure 45 and Figure 46 As shown, the switch inclined surface 133e of the switch 133 is parallel to and in contact with one of the pressing plate inclined surfaces 137f of the pressing plate fitting portion 137c.

[0296] The force applying portion 133b can be used by the user to apply force. When the user pushes or pulls the force applying portion 133b, the switch 133 can move relative to the bracket 132 and the pin 136 in the installation space 132b, wherein the pin 136 can guide and limit the switch 133. Figure 49 In the state shown, the switch 133 can be located at the right extreme position.

[0297] Figure 48 and Figure 49 The waterproof assembly 13 shown is in a connected state. Figure 49 As shown, the bracket through hole 132d, the second groove 11d and the shell through hole 11h on the left are connected in sequence to form a first channel t1, which connects the external environment with the shell space 11b; the bracket through hole 132d, the second groove 11d and the shell through hole 11h on the right are connected in sequence to form a second channel t2, which connects the external environment with the shell space 11b.

[0298] Thus, sound from outside the electronic device 10 can enter the interior of the electronic device 10 through the second channel t2 and be picked up by the microphone. External air can also enter the interior of the electronic device 10 through the first channel t1, ensuring balanced air pressure inside and outside the electronic device 10. Due to the presence of the first and second waterproof breathable membranes, external liquids cannot enter the interior of the electronic device 10, ensuring that the electronic device 10 is breathable and waterproof in everyday use.

[0299] refer to Figure 49 and Figure 46 As shown, when the user pushes force-applying portion 133b to the left, switch 133 moves leftward, and switch mating portion 133c moves within mating groove 137g of pressure plate mating portion 137c, along pressure plate inclined surface 137f, toward the top of pressure plate mating portion 137c. Simultaneously, pressure from switch mating portion 133c causes pressure plate 137 to move downward, compressing elastic member 135 and gradually moving seal 134 closer to housing through-hole 11h.

[0300] Figure 50 This indicates a state in which the two sealing members 134 are respectively pressed against the openings of the two shell through holes 11h and block the two shell through holes 11h. At this time, the waterproof component 13 is said to be in a disconnected state.

[0301] In this disconnected state, if Figure 50 As shown, the switch 133 will slide to the left limit position, and the switch matching portion 133c moves to the top of the pressure plate matching portion 137c. Figure 50 and Figure 46 As shown, the switch fitting portion 133c can be snapped into the limiting groove 137h at the top of the pressure plate fitting portion 137c. Thus, the switch 133 is locked in the left limit position, and the pressure plate 137 is locked in the corresponding position, thereby maintaining the waterproof component 13 in the disconnected state.

[0302] In this disconnected state, the first channel t1 and the second channel t2 are both blocked, and the exterior of the housing 11 is disconnected from the housing space 11b, preventing external liquid from entering the interior of the electronic device 10. Because the seal 134 has stable and reliable sealing performance, even if external liquid has a high pressure, it is difficult or impossible to enter the interior of the electronic device 10.

[0303] To use electronic device 10 in a high-pressure environment, the user can first deactivate switch 133, disabling waterproof assembly 13, and then carry electronic device 10 into the high-pressure environment. Because waterproof assembly 13 has already blocked the high-pressure liquid, the first and second waterproof breathable membranes are no longer subject to high pressure and are therefore less susceptible to damage. Therefore, electronic device 10 can operate reliably in high-pressure environments.

[0304] In summary, by pushing the switch 133, the waterproof component 13 is switched between the connected state and the disconnected state, which can not only make the electronic device 10 breathable and waterproof in daily scenarios, but also enable the electronic device 10 to work safely and reliably in a high water pressure environment.

[0305] Similar to the first embodiment, in the third embodiment, the status of the waterproof component 13 can be detected using a magnetic field sensor and a magnet, and prompt information can be sent based on the status detection results of the waterproof component 13. The magnetic field sensor and the magnet can be installed in appropriate locations. For example, the magnetic field sensor can be installed in the housing space 11b, and the magnet can be installed on the pressure plate 137. Alternatively, the status of the waterproof component 13 can be detected using a microphone and a speaker (a depth gauge can also be used), and prompt information can be sent based on the status detection results of the waterproof component 13. The specific principles are the same as those described above and will not be repeated here.

[0306] In other embodiments, the status of the waterproof component 13 may not be detected.

[0307] Example 4

[0308] like Figure 51 and Figure 52 As shown, the fourth embodiment provides an electronic device 20, which can be, for example, a smartwatch. The electronic device 20 may include a display 22, a housing 21 (e.g., a middle frame), a housing 23 (e.g., a rear housing), and a waterproof assembly 24. The display 22 and the housing 23 are mounted on opposite sides of the housing 21, and the display 22, the housing 21, and the housing 23 may enclose an inner cavity of the electronic device 20.

[0309] like Figure 53 and Figure 54 As shown, the structure of the housing 21 can be substantially the same as that of the aforementioned housing 11. The housing 21 has a housing space 21b, which also constitutes the inner cavity of the electronic device 20. The housing 21 is provided with a groove 21a, the opening of which is located on the outer peripheral side of the housing 21. The housing 21 differs from the aforementioned housing 11 in the structure of the groove 21a, which will be described below.

[0310] like Figure 54 and Figure 55 As shown, the opening of the groove 21a of the housing 21 may be approximately C-shaped. The groove 21a may include a groove area 21e and two groove areas 21d located on opposite sides of the groove area 21e. The groove area 21e is connected to the two groove areas 21d. The two groove areas 21d may serve as the two ends of the C-shape, and the groove area 21e may serve as the middle part of the C-shape.

[0311] like Figure 55As shown, the bottom surface of each recessed area 21d is provided with a housing through-hole 21g. Housing through-hole 21g may be spaced a certain distance from the side surface of recessed area 21d. Housing through-hole 21g may penetrate the bottom wall of recessed area 21d and communicate with housing space 21b of housing 21. In other words, recess 21a communicates with housing space 21b via housing through-hole 21g.

[0312] like Figure 55 As shown, two mounting grooves 21h may be opened on the bottom surface of the groove area 21e, and the two mounting grooves 21h may be located between the two housing through holes 21g.

[0313] like Figure 55 As shown, the side of the recessed area 21e may further include a protruding guide portion 21f. The guide portion 21f may be, for example, semi-cylindrical. The bottom surface of the recessed area 21e may further include a guide groove 21i. The guide groove 21i is connected to the guide portion 21f. The side of the guide groove 21i adjacent to the guide portion 21f may be cylindrical, and this cylindrical surface may be smooth with the cylindrical surface of the guide portion 21f. The side of the guide groove 21i distal to the guide portion 21f may communicate with the housing space 21b. Both the guide portion 21f and the guide groove 21i may be located between the two mounting grooves 21h.

[0314] like Figure 55 As shown, the housing 21 may further include a connection hole 21c. For example, there may be two connection holes 21c, which are located on both sides of the groove 21a. The connection holes 21c may be blind holes.

[0315] like Figure 56 and Figure 57 As shown, the waterproof assembly 24 may include a bracket 241 , a pin 245 , a switch 246 , a pressure plate 242 , a sealing member 243 and an elastic member 244 .

[0316] like Figure 58 and Figure 59 As shown, the bracket 241 can be approximately a hollow frame structure. The bracket 241 has a receiving space 241a. The bracket 241 can include a bracket base 241f and a bracket mating portion 241b, which can be connected, for example, as a whole. The bracket base 241f can have an opening 241h formed therein. The opening 241h can be approximately rectangular and communicate with the receiving space 241a. The bracket mating portion 241b can have an opening 241g formed therein. The opening 241g can be approximately arc-shaped and communicate with the receiving space 241a.

[0317] like Figure 58 and Figure 59As shown, the bracket base 241f may be approximately plate-shaped or block-shaped. The bracket base 241f may be provided with a connection hole 241c, a bracket through-hole 241d, and a matching hole 241e. There may be, for example, two connection holes 241c, which may be located at both ends of the bracket base 241f. The connection hole 241c is a through hole. There may be two bracket through-holes 241d, which may be located at both ends of the bracket base 241f, and both are located between the two connection holes 241c. The bracket through-hole 241d is a through hole, and the axes of the bracket through-hole 241d and the connection hole 241c may be substantially consistent. The matching hole 241e may be located between the two bracket through-holes 241d and pass through the bracket base 241f. The axis of the matching hole 241e may be substantially perpendicular to the axis of the bracket through-hole 241d.

[0318] like Figure 58 and Figure 59 As shown, the outer shape of the bracket matching portion 241b can be approximately a hollow semi-cylindrical shape. The bracket matching portion 241b can be located between the two connecting holes 241c on the bracket base 241f.

[0319] like Figure 57 As shown, the overall shape of the pin 245 can be approximately cylindrical or rod-shaped. The two ends of the pin 245 can be thicker, and the part between the two ends can be thinner. Figure 57 and Figure 58 As shown, the pin 245 can cooperate with the matching hole 241e, and both ends of the pin 245 can be exposed in the matching hole 241e. The above structure of the pin 245 enables the pin 245 to reliably cooperate with the matching hole 241e without detaching from the matching hole 241e.

[0320] like Figure 60 As shown, the switch 246 may include a force-applying portion 246a and a switch-matching portion 246b, which may be integrated into one body.

[0321] Among them, the force-applying portion 246a can be approximately a hemispherical structure. For example, there can be two force-applying portions 246a, and the two force-applying portions 246a can be located on both sides of the switch matching portion 246b. The force-applying portion 246a is used for the user to apply force so that the user can turn the switch 246. A pin hole 246c can be provided at one end of the switch matching portion 246b away from the force-applying portion 246a, and the pin hole 246c passes through the switch matching portion 246b. The axis of the pin hole 246c can be approximately parallel to the direction of the connection line between the two force-applying portions 246a. The surface of the end of the switch matching portion 246b away from the force-applying portion 246a can include an arc surface, and different positions on the arc surface have different distances from the center line of the pin hole 246c (this distance can be called a cam radius), that is, a cam structure can be formed at one end of the switch matching portion 246b away from the force-applying portion 246a.

[0322] like Figure 61 As shown, the pressing plate 242 may include a base plate 242a, an elastic member limiting portion 242d and a guide portion 242e.

[0323] like Figure 61 As shown, the base plate 242a can be approximately flat. The base plate 242a can have mounting holes 242b. For example, there can be two mounting holes 242b, one at each end of the base plate 242a. The edge of the base plate 242a can also be provided with guide grooves 242c, which can be, for example, semicircular grooves.

[0324] like Figure 61 As shown, the elastic member limiter 242d and the guide portion 242e are connected to the same side of the base plate 242a. Both can be protruding from the plate surface of the base plate 242a (the normal of the plate surface is along the thickness direction of the base plate 242a). There can be two elastic member limiters 242d, and the elastic member limiters 242d can be approximately cylindrical. The guide portion 242e can be located between the two elastic member limiters 242d. The guide portion 242e can be approximately flat. The side surface of the guide portion 242e can be smoothly connected to the inner surface of the guide groove 242c.

[0325] like Figure 62 As shown, the seal 243 can be a rotating body, one end of its axis (for example Figure 62 The lower end in the viewing angle) can be approximately conical. The sealing member 243 can be made of a sealing material with elasticity, such as rubber, silicone, etc.

[0326] like Figure 57 As shown, the elastic member 244 can be, for example, a spring, or other elastically retractable components. There can be two elastic members 244.

[0327] The assembly structure of the waterproof component 24 and the assembly structure of the waterproof component 24 and the housing 21 will be described below.

[0328] Figure 63 FIG. 2 is a schematic diagram of the assembly structure of the electronic device 20 at one viewing angle. Figure 64 and Figure 65 It can represent the assembly structure of the waterproof component 24, and an assembly state of the waterproof component 24 and the housing 21. Figure 64 for Figure 63 DD cross-sectional view of the electronic device 20, Figure 65 yes Figure 64 Schematic diagram of the local enlarged structure at F in the middle.

[0329] The first waterproof breathable membrane and the second waterproof breathable membrane ( Figure 65(not shown), the first waterproof breathable membrane can, for example, cover one end of the housing through hole 21g on the left side, and the second waterproof breathable membrane can, for example, cover one end of the housing through hole 21g on the right side. Both the first waterproof breathable membrane and the second waterproof breathable membrane are breathable and have a certain waterproof performance (can prevent liquid penetration and prevent liquid from passing through). A second microphone ( Figure 65 (Not shown). The microphone may correspond to the housing through hole 21g on the right side, for example.

[0330] The electronic device 20 may also be provided with a speaker and a controller ( Figure 65 (Not shown). The specific locations of the speaker and controller can be designed as needed. The sound emitted by the speaker can be transmitted outside the electronic device 20. The left housing through-hole 21g can serve as an air pressure balance hole for the speaker. The controller can be a central processing unit or a microcontroller unit (MCU).

[0331] Combine Figure 55 、 Figure 64 and Figure 65 As shown, the waterproof assembly 24 can be installed on the housing 21 and cover the opening of the groove 21 a of the housing 21 .

[0332] Combine Figure 55 、 Figure 64 and Figure 65 As shown, the bracket base 241f of the bracket 241 is matched with the surface where the opening of the groove 21a is located. Schematically, the connection hole 241c on the bracket base 241f and the connection hole 21c on the housing 21 can be fixedly connected by a connector 247, which can be a threaded connector (such as a screw, bolt, etc.). Figure 58 、 Figure 59 and Figure 55 As shown, the bracket through hole 241d on the bracket base 241f corresponds to and communicates with the groove area 21d in the groove 21a. In addition, the bracket matching portion 241b of the bracket 241 is located outside the groove 21a.

[0333] Combine Figure 64 and Figure 65 As shown, the switch 246 can be rotatably mounted on the bracket 241 through the pin 245. The switch matching portion 246b of the switch 246 can be located in the receiving space 241a of the bracket 241. The force-applying portion 246a of the switch 246 can be exposed from the opening 241g of the bracket matching portion 241b. Figure 65 、 Figure 60 、 Figure 58As shown, the pin shaft 245 can cooperate with the pin hole 246c of the switch matching portion 246b and the matching hole 241e of the bracket base 241f, so that the switch 246 can rotate around the pin shaft 245 in the receiving space 241a. Figure 65 In the state shown, the force applying portion 246 a may be located at the left limit position, and the force applying portion 246 a may abut against the bracket 241 .

[0334] like Figure 65 As shown, the pressing plate 242, the sealing member 243 and the elastic member 244 are all enclosed in the groove 21a of the housing 21 by the bracket 241. Figure 61 and Figure 65 As shown, seal 243 can pass through mounting hole 242b of pressure plate 242 and be fixedly connected to pressure plate 242. Seal 243 corresponds to housing through-hole 21g of housing 21, with the tip of seal 243 facing housing through-hole 21g. Seal 243 is located a certain distance from the opening of housing through-hole 21g. Elastic member 244 is located within mounting slot 21h of housing 21. One end of elastic member 244 abuts base plate 242a of pressure plate 242 and fits over the outer periphery of elastic member retaining portion 242d. The other end of elastic member 244 abuts the bottom surface of mounting slot 21h. Supported by the elastic force of elastic member 244, pressure plate 242 can contact and compress the area with the smaller cam radius on switch mating portion 246b. This area of ​​switch mating portion 246b and force-applying portion 246a can be located on either side of pin 245, ensuring that switch 246 maintains equilibrium under the action of two opposing torques. The guide portion 242e of the pressing plate 242 can be aligned with the guide groove 21i of the housing 21, and the end of the guide portion 242e is spaced a certain distance from the bottom surface of the guide groove 21i.

[0335] Figure 65 The waterproof assembly 24 is shown in a connected state. Figure 58 、 Figure 55 and Figure 65 As shown, a bracket through hole 241d, a groove 21a and a shell through hole 21g are connected in sequence to form a first channel, which connects the external environment with the shell space 21b; another bracket through hole 241d, a groove 21a and another shell through hole 21g are connected in sequence to form a second channel, which connects the external environment with the shell space 21b.

[0336] Thus, sound from outside electronic device 20 can enter through the second channel and be picked up by the second microphone. External air can also enter electronic device 20 through the first channel, ensuring balanced air pressure inside and outside electronic device 20. Due to the presence of the first and second waterproof breathable membranes, external liquids cannot enter the interior of electronic device 20, ensuring that electronic device 20 is breathable and waterproof in everyday use.

[0337] refer to Figure 65 As shown, when the user rotates the switch 246 clockwise, the switch 246 will rotate within the receiving space 241a. The switch mating portion 246b will press against the pressure plate 242, causing the pressure plate 242 to drive the sealing member 243 to move toward the housing through hole 21g. During this process, the guide portion 242e will move toward the bottom surface of the guide groove 21i, and the elastic member 244 will be gradually compressed. Figure 66 As shown, when the larger cam radius portion of the switch mating portion 246b contacts the pressure plate 242, the two seals 243 press against the openings of the two housing through-holes 21g, blocking them. At this point, the force-applying portion 246a can be located at the left extreme position, abutting against the bracket 241. The portion of the switch mating portion 246b that contacts the pressure plate 242 and the force-applying portion 246a can be located on either side of the pin 245, allowing the switch 246 to maintain a balanced state under the action of two opposing torques.

[0338] Figure 66 The waterproof assembly 24 is shown in a disconnected state. In this disconnected state, both the first and second passages are blocked, and the exterior of the housing 21 is disconnected from the housing space 21b, preventing external liquids from entering the interior of the electronic device 20. Because the seal 243 provides a stable and reliable sealing performance, even external liquids with high pressure are unlikely to enter the interior of the electronic device 20.

[0339] To use electronic device 20 in a high-pressure environment, the user can first deactivate switch 246 to disconnect waterproof assembly 24 before carrying electronic device 20 into the high-pressure environment. Because waterproof assembly 24 has already blocked the large amount of high-pressure liquid, the first and second waterproof breathable membranes are no longer subject to high pressure and are therefore less susceptible to damage. Therefore, electronic device 20 can operate reliably in high-pressure environments.

[0340] In summary, by rotating the switch 246, the waterproof component 24 is switched between the connected state and the disconnected state, which can not only make the electronic device 20 breathable and waterproof in daily scenarios, but also enable the electronic device 20 to work safely and reliably in a high water pressure environment.

[0341] Similar to the first embodiment, in the fourth embodiment, the status of the waterproof component 24 can be detected using a magnetic field sensor and a magnet, and prompt information can be sent based on the status detection results of the waterproof component 24. The magnetic field sensor and the magnet can be installed in appropriate locations. For example, the magnetic field sensor can be installed in the housing space 21b, and the magnet can be installed on the pressure plate 242. Alternatively, the status of the waterproof component 24 can be detected using a microphone and a speaker (a depth gauge can also be used), and prompt information can be sent based on the status detection results of the waterproof component 24. The specific principles are the same as those described above and will not be repeated here.

[0342] In other embodiments, the status of the waterproof component 24 may not be detected.

[0343] Example 5

[0344] like Figure 67 and Figure 68 As shown, Embodiment 5 provides an electronic device 30, which may be, for example, a smartwatch. The electronic device 30 may include a display 32, a housing 31 (e.g., a middle frame), a housing 34 (e.g., a rear housing), and a waterproof assembly 33. The display 32 and housing 34 are mounted on opposite sides of the housing 31. The display 32, housing 31, and housing 34 may enclose an inner cavity of the electronic device 30. The waterproof assembly 33 may be mounted on the housing 31.

[0345] like Figure 68 and Figure 69 As shown, the structure of the housing 31 is substantially the same as that of the housing 11 described above. For example, the outer shape of the housing 31 may be approximately annular. The housing 31 has a housing space 31b, which is part of the inner cavity of the electronic device 30. The housing 31 has a groove 31a, the opening of which is located on the outer peripheral side of the housing 31.

[0346] like Figure 69 、 Figure 70 and Figure 71 As shown, the groove 31a may be a stepped groove, and the groove 31a may include a first groove 31c and a second groove 31d. The opening of the first groove 31c may be larger than the opening of the second groove 31d.

[0347] like Figure 71 As shown, the bottom surface 31e of the first groove 31c may be provided with a connecting hole 31g, which may be a blind hole. For example, there may be two connecting holes 31g, which are respectively located on both sides of the bottom surface 31e.

[0348] like Figure 71As shown, the bottom surface 31f of the second groove 31d may define two housing through-holes 31h. Both housing through-holes 31h may be spaced apart from the side of the second groove 31d. Both housing through-holes 31h may extend through the bottom wall of the second groove 31d and communicate with the housing space 31b of the housing 31. In other words, the groove 31a communicates with the housing space 11b via the two housing through-holes 31h. The bottom surface 31f of the second groove 31d may also define a mounting groove 31i, which may be located between the two housing through-holes 31h.

[0349] like Figure 72 and Figure 73 As shown, the waterproof assembly 33 may include a bracket 331 , a pin 335 , a switch 332 , a pressure plate 336 , a sealing member 333 and an elastic member 334 .

[0350] like Figure 73 and Figure 74 As shown, the bracket 331 can be approximately a hollow frame structure. The bracket 331 can be provided with a connecting hole 331a, which is a through hole. For example, there can be two connecting holes 331a, one located at each end of the bracket 331. The connecting holes 331a are used to install a connecting piece. The bracket 331 can also be provided with a bracket through hole 331b, which is a through hole. There can be two bracket through holes 331b, each located between the two connecting holes 331a. The area on the bracket 331 between the two bracket through holes 331b can be hollowed out to form a receiving space 331c. A matching hole 331d can be provided on the wall of the receiving space 331c. The matching hole 331d is also located between the two bracket through holes 331b. The matching hole 331d can be a circular hole.

[0351] like Figure 73 As shown, the pin 335 may be approximately cylindrical or rod-shaped. Figure 73 and Figure 74 As shown, the pin 335 can be matched with the matching hole 331d on the bracket 331.

[0352] like Figure 75As shown, the switch 332 can be approximately a curved plate-like structure. The switch 332 has a pin hole 332b, which is a through hole and can be roughly located in the middle of the switch 332. The pin hole 332b is used to cooperate with the pin shaft 335. The switch 332 may include a force-applying portion 332a and a switch matching portion 332c, which can be connected as one body. The force-applying portion 332a is used for the user to apply force so that the user can turn the switch 332. The switch matching portion 332c is used to cooperate with the pressure plate 336. The surface of the force-applying portion 332a away from the switch matching portion 332c may include an arc surface, and different positions on the arc surface have different distances from the center line of the pin hole 332b (this distance can be called a cam radius), so the switch matching portion 332c can be said to form a cam.

[0353] like Figure 76 As shown, the pressure plate 336 may include a base plate 336a, a seal mounting portion 336c, and a pressure plate mating portion 336b. The base plate 336a may be approximately flat. The seal mounting portion 336c and the pressure plate mating portion 336b may be located on either side of the base plate 336a in the thickness direction. There may be two seal mounting portions 336c, each of which may be approximately cylindrical. The seal mounting portion 336c is used to mount the seal 333. The pressure plate mating portion 336b may be a convex bump or projection with an arcuate surface. The pressure plate mating portion 336b may mate with a cam on the switch mating portion 332c.

[0354] like Figure 73 As shown, the seal 333 can be a hollow rotating body, one end of the axis (for example Figure 73 The lower end in the perspective view can be approximately conical. The sealing member 333 can be made of a sealing material with elasticity, such as rubber, silicone, etc. The sealing member 333 can be sleeved on the sealing member mounting portion 336c.

[0355] like Figure 73 As shown, the elastic member 334 can be, for example, a spring or other elastically retractable component. The elastic member 334 is used to provide a rebound force to the pressing plate 336 .

[0356] The assembly structure of the waterproof component 33 and the assembly structure of the waterproof component 33 and the housing 31 will be described below.

[0357] Figure 77 and Figure 78 It can represent an assembly structure of the waterproof component 33 and the housing 31, as well as the assembly structure of the waterproof component 33. Figure 77 and Figure 71 Using the same GG cross section, Figure 78 yes Figure 77 Schematic diagram of the locally enlarged structure at K in the middle.

[0358] The first waterproof breathable membrane and the second waterproof breathable membrane ( Figure 78 (not shown), the first waterproof breathable membrane can, for example, cover one end of the housing through hole 31h on the left, and the second waterproof breathable membrane can, for example, cover one end of the housing through hole 31h on the right. Both the first waterproof breathable membrane and the second waterproof breathable membrane are breathable and have a certain waterproof performance (can prevent liquid penetration and prevent liquid from passing through). A microphone can also be installed in the housing space 31b ( Figure 78 (Not shown). The microphone may correspond to the housing through hole 31h on the right side, for example.

[0359] The electronic device 30 may also be provided with a speaker and a controller ( Figure 78 (Not shown). The specific locations of the speaker and controller can be designed as needed. The sound emitted by the speaker can be transmitted outside the electronic device 30. The left housing through-hole 31h can serve as an air pressure balance hole for the speaker. The controller can be a central processing unit or a microcontroller unit (MCU).

[0360] Combine Figure 71 、 Figure 72 and Figure 78 As shown, the waterproof component 33 can be installed in the groove 31 a of the housing 31 .

[0361] Among them, combined Figure 71 、 Figure 74 and Figure 78 Bracket 331 can be installed in first slot 31c of groove 31a. Illustratively, a connector 35 (e.g., a screw, bolt, or other threaded connector) can be inserted through connecting hole 331a on bracket 331 and connecting hole 31g on the bottom wall of first slot 31c to secure bracket 331 in first slot 31c. Bracket through hole 331b on bracket 331 communicates with second slot 31d of groove 31a.

[0362] Combine Figure 77 and Figure 78 As shown, the switch 332 can be installed in the receiving space 331c of the bracket 331 through the pin 335. Figure 73-75 as well as Figure 78 As shown, the pin 335 can cooperate with the matching hole 331d on the bracket 331 and the pin hole 332b on the switch 332, so that the switch 332 can rotate around the pin 335 in the receiving space 331c. Figure 78 In the state shown, the force applying portion 332 a may be located at the right limit position, and the force applying portion 332 a may abut against the bracket 331 .

[0363] Combine Figure 76 、 Figure 77 and Figure 78As shown, the pressure plate 336, the sealing member 333 and the elastic member 334 of the waterproof assembly 33 are all enclosed in the second groove 31d of the housing 31 by the bracket 331. Figure 76 and Figure 78 As shown, the seal 333 can be sleeved onto the seal mounting portion 336c of the pressure plate 336 and fixedly connected to the pressure plate 336. The seal 333 corresponds to the housing through hole 31h of the housing 31. The conical tip of the seal 333 can be oriented toward the housing through hole 31h, and the seal 333 is located a certain distance from the opening of the housing through hole 31h. A portion of the elastic member 334 is located within the mounting groove 31i of the housing 31, while the other portion extends out of the mounting groove 31i and is located within the second groove 31d. The ends of the elastic member 334 respectively abut against the bottom surface of the mounting groove 31i and the base plate 336a of the pressure plate 336. Under the elastic support of the elastic member 334, the base plate 336a of the pressure plate 336 can contact and squeeze the part with a smaller cam radius on the switch mating part 332c, and this part of the switch mating part 332c and the force-applying part 332a can be respectively located on both sides of the pin shaft 335, so that the switch 332 can maintain a balanced state under the action of two opposite torques.

[0364] Figure 78 The waterproof assembly 33 shown is in a connected state. Figure 78 As shown, the bracket through hole 331b, the second groove 31d and the shell through hole 31h on the left side are connected in sequence to form a first channel, which connects the external environment with the shell space 31b; the bracket through hole 331b, the second groove 31d and the shell through hole 31h on the right side are connected in sequence to form a second channel, which connects the external environment with the shell space 31b.

[0365] Thus, sound from outside the electronic device 30 can enter through the second channel and be picked up by the microphone. External air can also enter the electronic device 30 through the first channel, ensuring balanced air pressure inside and outside the electronic device 30. Thanks to the first and second waterproof breathable membranes, external liquids cannot enter the interior of the electronic device 30, ensuring that the electronic device 30 is breathable and waterproof in everyday use.

[0366] refer to Figure 78 As shown, when the user rotates the switch 332 counterclockwise, the switch 332 will rotate in the receiving space 331c. The switch matching portion 332c will press the pressure plate 336, so that the pressure plate 336 drives the sealing member 333 to move toward the housing through hole 31h. In this process, the elastic member 334 will be gradually compressed. Figure 79As shown, when the larger cam radius on the switch mating portion 332c contacts the pressure plate mating portion 336b, the two seals 333 press against the openings of the two housing through-holes 31h, blocking them. At this point, the force-applying portion 332a is positioned at the left extreme position, abutting against the bracket 241. The area where the switch mating portion 332c contacts the pressure plate 336 and the force-applying portion 332a are located on either side of the pin 335, allowing the switch 332 to maintain equilibrium under the action of two opposing torques.

[0367] Figure 79 The waterproof assembly 33 is shown in a disconnected state. In this disconnected state, both the first and second passages are blocked, and the exterior of the housing 31 is disconnected from the housing space 31b, preventing external liquids from entering the interior of the electronic device 30. Because the seal 333 provides a stable and reliable sealing performance, even external liquids with high pressure are unlikely to enter the interior of the electronic device 30.

[0368] To use electronic device 30 in a high-pressure environment, the user can first deactivate switch 332, disabling waterproof assembly 33, and then carry electronic device 30 into the high-pressure environment. Because waterproof assembly 33 has already blocked the high-pressure liquid, the first and second waterproof breathable membranes are no longer subject to high pressure and are therefore less susceptible to damage. Consequently, electronic device 30 can operate reliably in high-pressure environments.

[0369] In summary, by rotating the switch 332, the waterproof component 33 is switched between the connected state and the disconnected state, which can not only make the electronic device 30 breathable and waterproof in daily scenarios, but also enable the electronic device 30 to work safely and reliably in a high water pressure environment.

[0370] Similar to the first embodiment, in the fifth embodiment, the status of the waterproof component 33 can be detected using a magnetic field sensor and a magnet, and prompt information can be sent based on the status detection results of the waterproof component 33. The magnetic field sensor and the magnet can be installed in appropriate locations. For example, the magnetic field sensor can be installed in the housing space 31b, and the magnet can be installed on the pressure plate 336. Alternatively, the status of the waterproof component 33 can be detected using a microphone and a speaker (a depth gauge can also be used), and prompt information can be sent based on the status detection results of the waterproof component 33. The specific principles are the same as those described above and will not be repeated here.

[0371] In other embodiments, the status of the waterproof component 33 may not be detected.

[0372] In addition, reference Figure 78-Figure 79As shown, the waterproof component 33 basically does not protrude from the housing 31. When the switch 332 is turned, the switch 332 basically does not protrude from the housing 31. This is conducive to realizing the hidden design of the waterproof component and improving the appearance of the electronic device 30. Figure 76 and Figure 79 As shown, the pressing plate 336 may have a pressing plate matching portion 336 b in a convex shape, which allows the switch 332 to be made shorter to contact the pressing plate 336 , thereby facilitating a hidden design of the switch 332 .

[0373] Example 6

[0374] like Figure 80 and Figure 81 As shown, the electronic device 50 of Example 6 may include a housing 51, a housing 52, a waterproof component 53, and a waterproof breathable membrane 54. The housing 51 is mounted on one side of the housing 52, and the housing 51 and the housing 52 form an inner cavity of the electronic device 50. The inner cavity of the electronic device 50 may be equipped with a microphone, a speaker, and a controller. The specific locations of the microphone, speaker, and controller may be designed as needed. The controller may be a central processing unit or a microcontroller unit (MCU). The waterproof component 53 and the waterproof breathable membrane 54 may both be mounted on the housing 52.

[0375] like Figure 81 and Figure 82 As shown, the outer shape of the housing 51 can be approximately rectangular plate-shaped, for example. The surface of the housing 51 close to the inner cavity of the electronic device 50 has a groove 51 a, and the groove 51 a can be located at the edge of the housing 51.

[0376] like Figure 83 and Figure 84 As shown, the outer shape of the housing 52 can be approximately a square box with an opening. The housing 52 can include a peripheral side wall 52f and a bottom wall 52g. The peripheral side wall 52f and the bottom wall 52g enclose a housing space 52a. The housing space 53a is also part of the inner cavity of the electronic device 50. The opening of the housing space 52a is opposite to the bottom wall 52g.

[0377] like Figure 83 and Figure 84 As shown, the peripheral sidewall 52f is formed with a groove 52c, the opening of which faces the outside of the housing space 52a. The groove 52c can be, for example, a circular stepped groove. The bottom surface of the first groove (with a larger opening diameter) in the groove 52c can be provided with two bosses 52d, which can be located at opposite ends of a diameter of the first groove. The bottom surface of the second groove (with a smaller opening diameter) in the groove 52c can be provided with a through hole 52e, which connects the groove 52c with the housing space 52a.

[0378] like Figure 83 and Figure 84 As shown in Figure 84 , ventilation grooves 52b are formed on the surface of the circumferential side wall 52f facing away from the bottom wall 42h. The ventilation grooves 52b and the through holes 52e are located on the same side of the housing space 52a. The bottom surface of the ventilation grooves 52b is provided with housing through holes 52h, and the housing through holes 52h are communicated with the through holes 52e. Schematically, the center line of the housing through holes 52h and the center line of the through holes 52e may intersect perpendicularly.

[0379] As Figure 85 and Figure 86 shown in Figure 86 , the waterproof component 53 may include a switch 531, an elastic member 532, a switch sealing ring 533, a bushing 534, a bushing sealing ring 535, a switch limiting member 536 and a bushing limiting member 537. <00013…​​​​​​​​​​​​​​​The tube body 534i has a receiving hole 534h and a receiving groove 534g. The receiving hole 534h and the receiving groove 534g can form a stepped hole, with the opening diameter of the receiving groove 534g being larger than the diameter of the receiving hole 534h. The receiving hole 534h extends through the bottom surface of the mounting groove 534m, connecting the mounting groove 534m with the receiving groove 534g. The mounting groove 534m, the receiving hole 534h, and the receiving groove 534g can form the inner lumen of the tubing. A tubing connecting hole 534k is formed in the wall of the tube body 534i, connecting the tubing connecting hole 534k to the receiving hole 534h. The centerline of the tubing connecting hole 534k can, for example, intersect perpendicularly with the centerline of the receiving hole 534h.

[0383] like Figure 90 、 Figure 91 and Figure 92 As shown, the shape of the switch 531 can be roughly a rotating body. The switch 531 can include a switch cap 531a and a switch rod 531d, which can be connected as a whole.

[0384] The switch cap 531a can be shaped like a circular cover with an opening. The switch cap 531a can include a bottom wall 531b and a peripheral sidewall 531c surrounding the periphery of the bottom wall 531b. The inner surface of the peripheral sidewall 531c can be provided with two mating protrusions 531i, which can be located at opposite ends of a diameter of the peripheral sidewall 531c.

[0385] The switch rod 531d can be in the shape of a round rod. One end of the switch rod 531d is connected to the bottom wall 531b and is surrounded by the circumferential sidewall 531c, with a spacing therebetween. The switch rod 531d has an axial switch communication hole 531h and a radial switch communication hole 531g. The centerline of the axial switch communication hole 531h can be along the axial direction of the switch rod 531d, and the centerline of the radial switch communication hole 531g can be along the radial direction of the switch rod 531d. The radial switch communication hole 531g can be located at one end of the axial switch communication hole 531h and connected to the axial switch communication hole 531h. The end of the axial switch communication hole 531h away from the radial switch communication hole 531g can also pass through the bottom wall 531b. The outer circumference of the switch rod 531d may define two sealing grooves 531e, each of which circumscribes the axis of the switch rod 531d. Both sealing grooves 531e may be located on the side of the radial switch communication hole 531g facing away from the bottom wall 531b. A retaining groove 531f may be defined on the outer circumference of the end of the switch rod 531d facing away from the bottom wall 531b. The retaining groove 531f circumscribes the axis of the switch rod 531d.

[0386] like Figure 86As shown, the elastic member 532 can be, for example, a spring or other elastically retractable component. The switch seal 533 and the bar seal 535 can both be made of elastic sealing materials, such as rubber or silicone. The stopper 536 can be an open annular structure, such as an open retaining ring.

[0387] Figure 93 It shows the assembled cross-sectional structure of the housing 51, the housing 52 and the waterproof component 53, Figure 94 for Figure 93 Schematic diagram of the local enlarged structure at point B in the middle.

[0388] like Figure 93 and Figure 94 As shown, housing 51 is mounted on housing 52, with housing 51 covering housing space 52a of housing 52. Recess 51a of housing 51 communicates with housing space 52a of housing 52. Recess 51a corresponds to vent groove 52b, and the orthographic projection of vent groove 52b on housing 51 fits within recess 51a. A waterproof breathable membrane 54 is mounted within vent groove 52b, with a gap between it and recess 51a.

[0389] Combine Figure 94 、 Figure 87 and Figure 83 As shown, a portion of the head portion 534a of the bar tube 534 can be positioned within the first groove of the recess 52c and contact the bottom wall of the groove. The two positioning grooves 534f of the head portion 534a can mate with the two bosses 52d in the first groove, enabling the bar tube 534 to be positioned within the housing 52. A bar tube sealing ring 535 can be installed within the second groove of the recess 52c and compressed between the head portion 534a and the bottom wall of the second groove to provide a seal. The body 534i of the bar tube 534 can pass through the through-hole 52e and extend into the housing space 52a. The bar tube communication hole 534k in the body 534i communicates with the housing through-hole 52h. A bar tube retainer 537 located within the housing space 52a can be positioned around the outer circumference of the body 534i and fixedly connected to the body 534i (for example, the bar tube retainer 537 can be a nut threadedly connected to the body 534i). The bar tube stopper 537 contacts the inner wall of the housing 52. Thus, the bar tube 534 can be fixed to the housing 52 by the bar tube stopper 537.

[0390] like Figure 94 As shown, the switch rod 531d of the switch 531 can be located in the receiving hole 534h and the receiving groove 534g, and the radial switch connecting hole 531g is connected to the bar tube connecting hole 534k. Figure 94 and Figure 90As shown, the two switch seals 533 can be installed in the two corresponding sealing grooves 531e, and both switch seals 533 can contact the inner wall of the receiving hole 534h. The limiter 536 can be installed in the limiter groove 531f, and the limiter 536 can be spaced apart from the bottom wall of the receiving groove 534g. The switch cap 531a of the switch 531 can surround the outer circumference of the head 534a. The elastic member 532 is installed in the mounting groove 534m, with the opposite ends of the elastic member 532 respectively abutting the bottom wall of the mounting groove 534m and the bottom wall 531b of the switch cap 531a.

[0391] And, as Figure 95 As shown, the two mating protrusions 531i on the peripheral side wall 531c of the switch cap 531a can be respectively correspondingly snapped into the two third mating grooves 534e of the head 534a (due to the viewing angle, Figure 95 Only one mating protrusion 531i and one third mating groove 534e are shown. Figure 95 and Figure 94 As shown, due to the elastic force exerted by the elastic member 532 on the switch cap 531a, the switch cap 531a tends to move out of the housing space 52a. However, due to the limiting effect of the third engaging groove 534e on the engaging protrusion 531i, the switch cap 531a can remain stationary. Figure 94 In the state shown, the switch 531 may be in the second extreme position (or right extreme position).

[0392] Figure 94 The waterproof component 53 in the device is in a connected state. In the connected state, the axial switch connecting hole 531h, the radial switch connecting hole 531g, the bar tube connecting hole 534k and the shell through hole 52h are connected in sequence to form a channel, which connects the external environment with the shell space 52a. Therefore, when the electronic device 50 is working in daily scenarios, the sound from outside the electronic device 50 can enter the inside of the electronic device 50 through the channel and be picked up by the microphone. The outside air can also enter the inside of the electronic device 50 through the channel to ensure the balance of the internal and external air pressure of the electronic device 50. Due to the presence of the waterproof and breathable membrane 54, external liquids cannot enter the inside of the electronic device 50, thereby achieving the breathability and waterproofness of the electronic device 50 in daily scenarios.

[0393] Combine Figure 95 、 Figure 96 and Figure 97 As shown, the user can push the switch cap 531a along the axial direction of the switch cap 531a to move the mating protrusion 531i out of the third mating groove 534e, and then rotate the switch cap 531a to move the mating protrusion 531i from the second mating groove 534d to the first mating groove 534c. Figure 98As shown, under the elastic force of the elastic member 532, the switch cap 531a will move to the outside of the housing space 52a until the switch limit member 536 abuts against the bottom surface of the receiving groove 534g, and the switch 531 will be in the first limit position (or left limit position). Figure 98 and Figure 99 As shown, when the switch 531 is at the first extreme position, the mating protrusion 531i is located at an end of the first mating groove 534c away from the second mating groove 534d.

[0394] like Figure 98 As shown, when switch 531 is in the left extreme position, radial switch communication hole 531g is completely offset from bar tube communication hole 534k, with the centerline of radial switch communication hole 531g and the centerline of bar tube communication hole 534k forming a spatial angle. Furthermore, both switch sealing rings 533 are positioned between radial switch communication hole 531g and bar tube communication hole 534k. As a result, the aforementioned passage is blocked, and waterproof assembly 53 is in a disconnected state.

[0395] refer to Figure 98 As shown, in this disconnected state, when the electronic device 50 enters a high-pressure environment, liquid will flow from the axial switch communication hole 531h to the radial switch communication hole 531g. Once the liquid penetrates the assembly gap between the switch rod 531d and the tube body 534i, it is blocked by the switch seal 533 and cannot continue to penetrate into the housing space 52a. Furthermore, due to the presence of the bar seal 535, the liquid cannot enter the housing space 52a via the groove 52c. Therefore, in this disconnected state, liquid cannot enter the internal cavity of the electronic device 50 regardless of the path it takes.

[0396] In the sixth embodiment, radial switch communication hole 531g is offset from valve tube communication hole 534k, and switch seal ring 533 and valve tube seal ring 535 block the liquid infiltration path, thereby blocking a large amount of high-pressure liquid from entering. This prevents the waterproof breathable membrane 54 from being subjected to high pressure and is therefore less susceptible to damage. As a result, electronic device 50 can operate reliably in high-pressure environments.

[0397] It is easy to understand that when the electronic device 50 leaves the high water pressure environment and enters the daily environment, Figure 98 and Figure 95 The user can first push and then rotate the switch cap 531a, causing the mating protrusion 531i to move from the first mating groove 534c to the third mating groove 534e and engage with the third mating groove 534e, thereby placing the waterproof assembly 53 in a connected state. By pushing and rotating the switch cap 531a, the waterproof assembly 53 can be switched between the connected and disconnected states, ensuring that the electronic device 50 is both breathable and waterproof in daily use and that it can operate safely and reliably in high-pressure environments.

[0398] Similar to the first embodiment, in the sixth embodiment, the status of the waterproof component 53 can be detected by a magnetic field sensor and a magnet, and a prompt message can be sent based on the status detection result of the waterproof component 53. The magnetic field sensor and the magnet can be installed in appropriate locations. For example, the magnetic field sensor can be installed in the housing space 52a, and the magnet can be installed at the end of the switch rod 531d facing away from the switch cap 531a. And / or, the status of the waterproof component 53 can also be detected by a microphone and a speaker (a depth gauge can also be used), and a prompt message can be sent based on the status detection result of the waterproof component 53. The specific principles are the same as those described above and will not be repeated here.

[0399] In other embodiments, the status of the waterproof component 53 may not be detected.

[0400] Example 7

[0401] like Figure 100 and Figure 101 As shown, the electronic device 40 of the seventh embodiment may include a housing 41, a housing 42, a waterproof component 43, and a waterproof breathable membrane 44. Among them, the housing 41 is installed on one side of the housing 42, and together with the housing 42, the housing can enclose the inner cavity of the electronic device 40. The inner cavity of the electronic device 40 can be installed with a microphone, a speaker, and a controller. The specific positions of the microphone, speaker, and controller can be designed as needed. The controller can be a central processing unit or a microcontroller unit (MCU). The waterproof component 43 and the waterproof breathable membrane 44 can both be installed on the housing 42.

[0402] like Figure 102 As shown, the outer shape of the housing 41 can be approximately rectangular plate-shaped. The surface of the housing 41 close to the inner cavity of the electronic device 40 has a groove 41 a, and the groove 41 a can be located at the edge of the housing 41.

[0403] like Figure 103 and Figure 104 As shown, the housing 42 can be approximately a square box with an opening. The housing 42 can include a peripheral side wall 42f and a bottom wall 42h. The peripheral side wall 42f and the bottom wall 42h enclose a housing space 42a, which is also part of the inner cavity of the electronic device 40. The opening of the housing space 42a is opposite to the bottom wall 42h.

[0404] like Figure 103 and Figure 104As shown, the peripheral sidewall 42f is formed with a groove 42b, which opens toward the outside of the housing space 42a. Illustratively, the groove 42b can be rectangular. The bottom surface of the groove 42b can form a boss 42d, which is approximately cylindrical and has a height that does not exceed the depth of the groove 42b. A through hole 42c is defined within the boss 42d, connecting the groove 42b with the housing space 42a.

[0405] like Figure 103 and Figure 104 As shown, a vent groove 42e is defined on the surface of the peripheral sidewall 42f facing away from the bottom wall 42h. Ventilation groove 42e and through-hole 42c are located on the same side of the housing space 42a. A housing through-hole 42g is defined on the bottom surface of vent groove 42e, communicating with through-hole 42c. Schematically, the centerline of housing through-hole 42g may intersect perpendicularly with the centerline of through-hole 42c.

[0406] like Figure 105 and Figure 106 As shown, the waterproof component 43 may include a switch 431 , a sealing ring 432 , an elastic member 433 and a limiting member 434 .

[0407] like Figure 106 and Figure 107 As shown, the switch 431 may include a switch plate 431a and a switch rod 431b, wherein the switch plate 431a is connected to the end of the switch rod 431b. The switch plate 431a may be approximately rectangular, the switch rod 431b may be approximately cylindrical, and the axis of the switch rod 431b may be perpendicular to the switch plate 431a.

[0408] like Figure 107 As shown, a connecting hole 431f is defined on the surface of switch plate 431a facing away from switch lever 431b. Connecting hole 431f extends along the axis of switch lever 431b into switch lever 431b, but does not penetrate the switch lever 431b. A connecting hole 431e is defined on the circumferential surface of switch lever 431b. Connecting hole 431e communicates with connecting hole 431f, and illustratively, the axes of the two holes may intersect perpendicularly.

[0409] like Figure 107 As shown, the circumferential surface of the switch rod 431b has a sealing groove 431c, which surrounds the axis of the switch rod 431b. There can be multiple sealing grooves 431c, for example, three. There are intervals between the multiple sealing grooves 431c. Among them, there can be at least one sealing groove 431c on each side of the connecting hole 431e. For example, Figure 107 From the perspective, there are two sealing grooves 431c on the left side of the communicating hole 431e, and one sealing groove 431c on the right side of the communicating hole 431e.

[0410] like Figure 107As shown, a limiting groove 431d is provided on the circumferential surface of one end of the switch rod 431b away from the switch plate 431a, and the limiting groove 431d can surround the axis of the switch rod 431b.

[0411] like Figure 106 As shown, the elastic member 433 may be, for example, a spring, or other elastically extendable member.

[0412] like Figure 106 As shown, the sealing ring 432 can be annular. The sealing ring 432 can be made of elastic sealing material, such as rubber silicone. The number of sealing rings 432 can be consistent with the number of sealing grooves 431c, for example, three. Figure 106 and Figure 107 As shown, a sealing ring 432 is correspondingly installed in a sealing groove 431c.

[0413] like Figure 106 As shown, the limiting member 434 may be an annular structure with an opening, and the limiting member 434 may be, for example, an open retaining ring.

[0414] Figure 108 and Figure 109 It can represent the assembly structure of the waterproof component 43, and an assembly state of the waterproof component 43 and the housing 42. Figure 108 for Figure 100 AA cross-sectional view of the electronic device 40, Figure 109 yes Figure 108 Schematic diagram of the local enlarged structure at point B in the middle.

[0415] like Figure 108 and Figure 109 As shown, housing 41 is mounted on housing 42, with housing 41 covering housing space 42a within housing 42. Recess 41a in housing 41 communicates with housing space 42a within housing 42. Recess 41a corresponds to vent groove 42e, and the orthographic projection of vent groove 42e on housing 41 fits within recess 41a. A waterproof breathable membrane 44 is mounted within vent groove 42e, with a gap between it and recess 41a.

[0416] like Figure 109 As shown, the switch 431 can be installed in the through hole 42c of the housing 42, wherein the switch plate 431a and a portion of the switch rod 431b are located in the groove 42b of the housing 42, and the other portion of the switch rod 431b passes through the through hole 42c and extends into the housing space 42a of the housing 42. The fit between the switch plate 431a and the groove 42b allows the switch 431 to move within the through hole 42c, but not to rotate. Figure 109 In the state shown, there is a gap between the switch 431 and the boss 42d, and the switch 431 is in the first limit position (or the left limit position).

[0417] like Figure 109 As shown, the stopper 434 can be engaged with the stopper groove 431d of the switch rod 431b and contact the housing 42. The outer diameter of the stopper 434 is larger than the inner diameter of the through hole 42c of the housing 42, thus preventing the switch 431 from being disengaged from the through hole 42c. The elastic member 433 is sleeved around the outer periphery of the boss 42d. One end of the elastic member 433 abuts the bottom surface of the groove 42b, and the other end abuts the surface of the switch plate 431a facing the switch rod 431b.

[0418] Figure 109 In the state shown, the waterproof component 43 is in a connected state. In this connected state, the connecting hole 431e is aligned with and connected to the shell through hole 42g. The connecting hole 431f, the connecting hole 431e, the shell through hole 42g and the groove 41a form a channel. As a result, the sound from outside the electronic device 40 can enter the inside of the electronic device 40 through the channel and be picked up by the microphone. The outside air can also enter the inside of the electronic device 40 through the channel to ensure the balance of the internal and external air pressure of the electronic device 40. Due to the presence of the waterproof and breathable membrane 44, external liquids cannot enter the interior of the electronic device 40, thereby enabling the electronic device 40 to be breathable and waterproof in daily scenarios.

[0419] When the electronic device 40 enters a high water pressure environment, Figure 109 As shown, the liquid entering the groove 42b exerts rightward pressure on the switch plate 431a, causing the switch 431 to move toward the housing space 42a. As the switch 431 moves, the communication hole 431e gradually becomes misaligned with the housing through hole 42g.

[0420] like Figure 110 As shown, until the switch plate 431a abuts the boss 42d, the connecting hole 431e is completely offset from the housing through hole 42g, and the above-mentioned passage is blocked, the switch 431 moves to the second limit position (or the right limit position). In addition, there is a sealing ring 432 on the left side of the housing through hole 42g. After the liquid in the groove 42b enters the clearance between the inner wall of the through hole 42c and the switch rod 431b, it is blocked by the sealing ring 432 on the left side of the housing through hole 42g and cannot enter the housing through hole 42g. There is a sealing ring 432 on each side of the connecting hole 431e. After the liquid in the connecting hole 431e enters the clearance between the inner wall of the through hole 42c and the switch rod 431b, it is blocked by the two sealing rings 432 on the left and right sides of the connecting hole 431e. The liquid cannot enter either the housing through hole 42g or the housing space 42a. Therefore, no matter which path the liquid takes, it cannot enter the inner cavity of the electronic device 40.

[0421] Figure 110In the illustrated state, waterproof assembly 43 is in a disconnected state. In this disconnected state, the passage is blocked, disconnecting the exterior of housing 42 from housing space 42a, preventing external liquid from entering the interior of electronic device 40. Hydraulic pressure is used to offset communication hole 431e from housing through-hole 42g, and sealing ring 432 blocks the liquid's infiltration path, keeping out large amounts of high-pressure liquid. This eliminates the need for waterproof breathable membrane 44 to withstand high pressure and, therefore, reduces damage. Consequently, electronic device 40 can operate reliably in high-pressure environments.

[0422] It is easy to understand that when the electronic device 40 leaves the high water pressure environment and enters the daily environment, the switch 431 will automatically return to the first extreme position, and the waterproof component 43 will automatically return to the connected state.

[0423] To sum up, the waterproof component 43 of the electronic device 40 can automatically switch between the connected state and the disconnected state under different pressures, which can not only make the electronic device 40 breathable and waterproof in daily scenarios, but also enable the electronic device 40 to work safely and reliably in a high water pressure environment.

[0424] Similar to the first embodiment, in the seventh embodiment, the status of the waterproof component 43 can be detected by a magnetic field sensor and a magnet, and a prompt message can be sent based on the status detection result of the waterproof component 43. The magnetic field sensor and the magnet can be installed in appropriate locations. For example, the magnetic field sensor can be installed in the housing space 42a, and the magnet can be installed at the end of the switch rod 431b facing away from the switch plate 431a. And / or, the status of the waterproof component 43 can also be detected by a microphone and a speaker (a depth gauge can also be used), and a prompt message can be sent based on the status detection result of the waterproof component 43. The specific principles are the same as described above and will not be repeated here.

[0425] In other embodiments, the status of the waterproof component 43 may not be detected.

[0426] Example 8

[0427] like Figure 111 and Figure 112 As shown, the electronic device 60 of the eighth embodiment may be, for example, a smart watch, and the electronic device 60 may include a display screen 62 , a housing 61 , a housing 63 and a waterproof component 64 .

[0428] The display screen 62 and housing 63 are mounted on opposite sides of the housing 61. The display screen 62, housing 61, and housing 63 can enclose the inner cavity of the electronic device 60. The inner cavity of the electronic device 60 can be equipped with a microphone, a speaker, a controller, a first waterproof breathable membrane, and a second waterproof breathable membrane. The specific locations of the microphone, speaker, and controller can be designed as needed. The controller can be a central processing unit (CPU) or a microcontroller unit (MCU). The first waterproof breathable membrane and the second waterproof breathable membrane can be mounted on the outside of a waterproof assembly 64 (described below). The waterproof assembly 64 can be mounted on the inside of the housing 61.

[0429] like Figure 113 and Figure 114 As shown, the shell 61 can be roughly annular, and the shell 61 has a shell space 61a, which is part of the inner cavity of the electronic device 60.

Specifically, the receiving shell liquid inlet hole 644c can correspond to both of the two limiting bosses 644d, and the top surface of each limiting boss 644d (the surface facing away from the inner wall of the receiving hole 644f) can be projected along the z-axis within the projection of the receiving shell liquid inlet hole 644c along the z-axis.

[0433] like Figure 116 and Figure 117 As shown, the upper side of the housing shell 644 can be provided with a fourth housing shell through hole 644g, and the center line of the fourth housing shell through hole 644g can be along Figure 116 In the y-axis direction shown, the fourth housing shell through hole 644g connects the exterior of the housing shell 644 with the housing hole 644f.

[0434] like Figure 116 and Figure 118 As shown, the lower side of the receiving shell 644 can be provided with a third receiving shell through hole 644b, and the center line of the third receiving shell through hole 644b can be along Figure 116 In the y-axis direction shown, the third housing shell through hole 644b connects the exterior of the housing shell 644 with the housing hole 644f. The third housing shell through hole 644b and the first housing shell through hole 644a may be located to the left of the housing shell liquid inlet 644c.

[0435] In the eighth embodiment, the structures of the first switch 643 and the second switch 645 may be consistent, and the following description will be made taking the second switch 645 as an example.

[0436] like Figure 119 As shown, the second switch 645 may include a second switch cylinder 645h and a second sealing member 645a.

A second connecting hole 645d and a fourth connecting hole 645i may be defined on the circumferential surface of the second main body 645f. The second connecting hole 645d and the fourth connecting hole 645i may be connected, and their centerlines may intersect perpendicularly. The second guide portion 645g may be generally rectangular and may be connected to a bottom surface of the second main body 645f.

[0438] like Figure 119 As shown, the second sealing member 645a can be fixed to the circumferential surface of the second main body 645f and protrude relative to the circumferential surface of the second main body 645f. The second sealing member 645a can include a plurality of circumferential portions 645b and a plurality of axial portions 645c. The number of circumferential portions 645b and axial portions 645c can be designed as needed, for example, three circumferential portions 645b and two axial portions 645c. The circumferential portions 645b surround the circumference of the second main body 645f, with spaces between adjacent circumferential portions 645b. The axial portions 645c extend axially along the second main body 645f, with spaces between adjacent axial portions 645c. Each axial portion 645c is interconnected with all the circumferential portions 645b. As a result, all the axial portions 645c intersect with all the circumferential portions 645b in a longitudinal and transverse manner, creating a plurality of regions on the circumferential surface of the second main body 645f. In this example, each of these regions can be referred to as a sealing region. The opening of the second communication hole 645d is located in one sealed area, and the opening of the fourth communication hole 645i is located in another adjacent sealed area.

[0439] The second sealing member 645a can be made of an elastic sealing material, such as rubber, silicone, etc.

[0440] like Figure 115 As shown, the first elastic member 642 and the second elastic member 646 can both be springs. In other embodiments, other components that can provide elastic force can also be used to replace the springs.

[0441] In the eighth embodiment, the structures of the first end cover 641 and the second end cover 647 may be consistent, and the following description will be made taking the first end cover 641 as an example.

[0442] like Figure 120 As shown, the first end cover 641 may include a cover plate 641a and a matching portion 641b protruding from the cover plate 641. The first end cover 641 may also have a through hole 641c, which may pass through the cover plate 641 and the matching portion 641b.

[0443] Figure 121 This is a schematic diagram of the exploded structure of the waterproof component 64. In order to clearly express the positional relationship between the receiving shell 644 and other components, the components other than the receiving shell 644 are displayed in an assembled manner, and the receiving shell 644 is displayed in an exploded manner.

[0444] refer to Figure 121As shown, both the first switch 643 and the second switch 645 can be installed within the receiving hole 644f of the receiving shell 644, and are located on either side of the limiting boss 644d. The limiting boss 644d can limit the first and second switches 643 and 645. The first main body of the first switch 643 and the second main body of the second switch 645 can be arranged facing each other, and the first guide portion of the first switch 643 and the second guide portion of the second switch 645 can be arranged facing away from each other. The first sealing member of the first switch 643 and the second sealing member of the second switch 645 can both slide in contact with the inner wall of the receiving hole 644f.

[0445] refer to Figure 121 As shown, the first connecting hole 643i on the first switch 643 can be connected to the first receiving shell through hole 644a, and the centerline of the first connecting hole 643i can substantially coincide with the centerline of the first receiving shell through hole 644a. The third connecting hole 643d on the first switch 643 can be connected to the third receiving shell through hole 644b, and the centerline of the third connecting hole 643d can substantially coincide with the centerline of the third receiving shell through hole 644b. Similarly, the second connecting hole 645d on the second switch 645 can be connected to the second receiving shell through hole 644e, and the centerline of the second connecting hole 645d can substantially coincide with the centerline of the second receiving shell through hole 644e. The fourth connecting hole 645i on the second switch 645 can be connected to the fourth receiving shell through hole 644g, and the centerline of the fourth connecting hole 645i can substantially coincide with the centerline of the fourth receiving shell through hole 644g.

[0446] refer to Figure 121 As shown, the first end cover 641 is fixed to the left end of the receiving shell 644. Figure 121 and Figure 120 As shown, the cover plate 641a in the first end cap 641 covers the left opening of the receiving hole 644f, and the mating portion 641b in the first end cap 641 extends into the receiving hole 644f. The first elastic member 642 can be sleeved around the outer periphery of the mating portion 641b, with one end of the first elastic member 642 abutting the cover plate 641a and the other end abutting the first main body of the first switch 643.

[0447] Figure 122 The assembly structure of the waterproof component 64 and the shell 61 can be represented, wherein the waterproof component 64 located in the shell 61 is shown with a dotted line. Figure 123 yes Figure 122 EE cross-sectional view of the structure shown, Figure 124 yes Figure 123 A partial enlarged view of point H in the middle. Figure 125 yes Figure 122 A partial enlarged view of the FF cross-sectional structure.

[0448] Combine Figure 113 As described above, a portion of the receiving shell 644 is fixed in the mounting groove 61b of the housing 61. Figure 113 and Figure 124 As shown, the portion of the receiving shell 644 where the fourth receiving shell through hole 644g is provided can be exposed outside the mounting groove 61b and located in the shell space 61a of the shell 61. Figure 125 As shown, the portion of the receiving shell 644 provided with the third receiving shell through hole 644b can also be exposed outside the mounting groove 61b and located within the housing space 61a of the shell 61. Therefore, the fourth receiving shell through hole 644g and the third receiving shell through hole 644b are both connected to the housing space 61a.

[0449] refer to Figure 125 As shown, the first waterproof breathable membrane can be fixed to the lower surface of the receiving shell 644 and block the opening of the third receiving shell through hole 644b. The first microphone can be arranged close to the first waterproof breathable membrane. Figure 124 As shown, the second waterproof breathable membrane can be fixed to the upper surface of the receiving case 644 and cover the opening of the fourth receiving case through hole 644g. The microphone can be arranged close to the second waterproof breathable membrane.

[0450] Figure 126 yes Figure 122 DD cross-sectional view, Figure 127 yes Figure 126 The schematic diagram of the local enlarged structure at G in the middle. Figure 127 As shown, the first housing through-hole 61e communicates with the first receiving shell through-hole 644a, and their centerlines can substantially coincide. The housing liquid inlet 61d communicates with the receiving shell liquid inlet 644c, which in turn communicates with the receiving shell liquid inlet 644f. The second housing through-hole 61c communicates with the second receiving shell through-hole 644e, and their centerlines can substantially coincide.

[0451] In summary and combined Figure 127 and Figure 125 It can be seen that the first shell through hole 61e, the first receiving shell through hole 644a, the first connecting hole 643i, the third connecting hole 643d and the third receiving shell through hole 644b are connected in sequence to form a first channel, which connects the outside of the electronic device 60 with the shell space 61a. The first channel can be used as an air pressure balance channel for the speaker. Similarly, in summary and in combination Figure 127 and Figure 124 As can be seen, the second housing through hole 61c, the second receiving shell through hole 644e, the second communication hole 645d, the fourth communication hole 645i, and the fourth receiving shell through hole 644g are sequentially connected to form a second channel, which connects the exterior of the electronic device 60 with the housing space 61a. This second channel can serve as a sound pickup channel for a microphone, for example.

[0452] In the eighth embodiment, it can be called Figures 121-127 The waterproof component 64 is in a connected state. In this connected state, when the electronic device 60 is used in daily scenarios, sound from outside the electronic device 60 can enter the electronic device 60 through the second channel and be picked up by the microphone. Outside air can also enter the electronic device 60 through the first channel, ensuring the internal and external air pressure balance of the electronic device 60. Due to the presence of the first waterproof breathable membrane and the second waterproof breathable membrane, external liquids cannot enter the electronic device 60, thus ensuring that the electronic device 60 is breathable and waterproof in daily scenarios.

[0453] When the electronic device 60 enters a high water pressure environment, Figure 127 As shown, liquid sequentially enters receiving hole 644f through the housing's liquid inlet hole 61d and the housing's liquid inlet hole 644c. The liquid entering receiving hole 644f pushes the first switch 643 to the left and the second switch 645 to the right, respectively, causing the first connecting hole 643i to gradually shift away from the first housing's through hole 644a, and the second connecting hole 645d to gradually shift away from the second housing's through hole 644e. As the first and second switches 643 and 645 move, the first and second elastic members 642 and 646 are gradually compressed.

[0454] Figure 128 Adopted with Figure 127 The same view expression, Figure 128 The cross-sectional view shows the state of the waterproof component 64 after the first switch 643 moves to the left limit position and the second switch 645 moves to the right limit position. Figure 129 Represented in a stereogram Figure 128 The status of the waterproof component 64 in.

[0455] like Figure 128 and Figure 129As shown, when the first switch 643 moves to the left extreme position, the first guide portion 643g of the first switch 643 can pass through the first end cap 641, and the first main portion 643f of the first switch 643 can abut against the first end cap 641. The first connecting hole 643i is completely offset from the first housing shell through hole 644a, and the projection of the first housing shell through hole 644a along its own centerline and the first connecting hole 643i are located in different sealing areas on the first switch 643. In addition, the projection of the first housing shell through hole 644a along its own centerline and the projection of the third housing shell through hole 644b along its own centerline also fall into different sealing areas on the first switch 643. For the convenience of the following description, the sealing area where the projection of the first housing shell through hole 644a along its own centerline falls can be referred to as the first sealing area.

[0456] Similar, such as Figure 128 and Figure 129 As shown, when the second switch 645 moves to the right limit position, the second guide portion 645g of the second switch 645 can extend out of the second end cap 647, and the second main portion 645f of the second switch 645 can abut against the second end cap 647. The second communication hole 645d is completely offset from the second housing shell through hole 644e, and the projection of the second housing shell through hole 644e along its own centerline and the second communication hole 645d are located in different sealing areas on the second switch 645. Furthermore, the projection of the second housing shell through hole 644e along its own centerline and the projection of the fourth housing shell through hole 644g along its own centerline also fall into different sealing areas on the second switch 645. For the convenience of the following description, the sealing area where the projection of the second housing shell through hole 644e along its own centerline falls may be referred to as the second sealing area.

[0457] Combine Figure 128 and Figure 129 As shown, after liquid enters the first housing through-hole 644a through the first housing through-hole 61e, it enters the first sealed area. The sealing material surrounding the first sealed area blocks the liquid's flow path in all directions, forcing the liquid to remain within the first sealed area. It cannot penetrate the first communication hole 643i and the third housing through-hole 644b, and thus cannot enter the housing space 61a. In other words, this first passage is blocked, preventing liquid from entering the housing space 61a along this first passage.

[0458] Similarly, combined Figure 128 and Figure 129As shown, after the liquid enters the second housing through-hole 644e through the second housing through-hole 61c, it enters the second sealed area. The sealing material surrounding the second sealed area blocks the liquid's flow path in all directions, forcing the liquid to remain within the second sealed area. However, the liquid cannot penetrate the second communication hole 645d or the fourth housing through-hole 644g, and thus cannot enter the housing space 61a. In other words, this second passage is blocked, preventing the liquid from entering the housing space 61a along this second passage.

[0459] Figure 128 and Figure 129 In the illustrated state, waterproof assembly 64 is in a disconnected state. In this disconnected state, both the first and second channels are blocked, disconnecting the exterior of housing 61 from housing space 61a, preventing external liquid from entering the interior of electronic device 60. Hydraulic pressure is used to offset the first communication hole 643i from the first housing through-hole 644a, and the second communication hole 645d from the second housing through-hole 644e. A sealing area is used to block the liquid's infiltration path, keeping out large amounts of high-pressure liquid. This eliminates the need for the first and second waterproof breathable membranes to withstand high pressure and, therefore, is less susceptible to damage. Consequently, electronic device 60 can operate reliably in high-pressure environments.

[0460] It is easy to understand that when the electronic device 60 leaves the high water pressure environment and enters the daily environment, the first switch 643 and the second switch 645 will automatically return to contact with the limiting boss 644d, and the waterproof component 64 will automatically return to the connected state.

[0461] To sum up, the waterproof component 64 of the electronic device 60 can automatically switch between the connected state and the disconnected state under different pressures, which can not only make the electronic device 60 breathable and waterproof in daily scenarios, but also enable the electronic device 60 to work safely and reliably in high water pressure environments.

[0462] Similar to the first embodiment, in the eighth embodiment, the status of the waterproof component 64 can be detected using a magnetic field sensor and a magnet, and a prompt message can be sent based on the status detection result of the waterproof component 64. The magnetic field sensor and the magnet can be installed in appropriate locations. For example, the magnetic field sensor can be installed in the housing space 61a, and the magnet can be installed on the first switch 643 and / or the second switch 645. Alternatively, the status of the waterproof component 64 can be detected using a microphone and a speaker (a depth gauge can also be used), and a prompt message can be sent based on the status detection result of the waterproof component 64. The specific principles are the same as those described above and will not be repeated here.

[0463] In other embodiments, the status of the waterproof component 64 may not be detected.

[0464] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
