Description

Blocking modules, devices, wearable devices, electronic devices

[0001] This application claims priority to Chinese Patent Application No. 202510006003.4, filed with the State Intellectual Property Office of China on January 2, 2025, entitled "Blocking Module, Surface Body, Wearable Device, Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of wearable device technology, and more particularly to a blocking module, a watch body including the blocking module, a wearable device including the watch body, and an electronic device including the blocking module. Background Technology

[0003] Wearable devices generally refer to miniature electronic devices that can be worn on the body for activities, and can include smartwatches and smart bracelets.

[0004] Wearable devices are being used in increasingly complex environments, such as deep water, which necessitates high levels of waterproofing. Currently, some wearable devices have low waterproof ratings, for example, only usable in water depths of less than 100 meters. Therefore, to further improve performance, the waterproofing structure of wearable devices needs optimization to meet the demands of deeper water environments. Summary of the Invention

[0005] This application provides a sealing module, a watch body including the sealing module, a wearable device including the watch body, and an electronic device including the sealing module. The aim is to provide a sealing module with waterproof functionality that can be used in deeper waters.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0007] In one aspect, this application provides a blocking module that can be applied in wearable devices, such as watches or bracelets.

[0008] The sealing module provided in this application includes a support member, which can be the mid-frame of the wearable device. The support member has a vent hole that can connect the outside and inside of the wearable device. For example, the vent hole can be a microphone hole or a pressure equalization hole. The sealing module also includes a sealing element, an elastic element, and a shape memory alloy element. The sealing element is disposed on the support member and can switch between a sealed state and an open state. In the sealed state, the sealing element seals the vent hole. In the open state, the sealing element moves away from the vent hole.

[0009] In addition, the shape memory alloy component connects the support component and the sealing component; in the sealed state, the elastic component provides elastic force to the sealing component to move closer to the vent, and in the open state, the shape memory alloy component provides elastic force to the sealing component to move away from the vent.

[0010] This application employs two structural components to apply elastic force to the sealing component: an elastic component and a shape memory alloy component. The elastic component provides elastic force to the sealing component, causing it to move closer to the vent, thus sealing the vent and blocking it. The shape memory alloy component provides elastic force to the sealing component, causing it to move away from the vent, thus opening the vent. When the vent is not needed to connect with the wearable device, no voltage is applied to the shape memory alloy component, and the sealing component remains normally closed under the action of the elastic component. When communication is required, or when the vent (such as a microphone hole) needs to connect with the outside, voltage is applied to the shape memory alloy component. The component heats up and deforms, lifting the sealing component and allowing the vent to connect with the outside.

[0011] Based on the above explanation of the working principle of the sealing component, it can be concluded that the sealing component is usually in a normally closed state, that is, it is a normally closed sealing structure. Therefore, even in a water environment of 100 meters or even more than 200 meters, the sealing component is in a normally closed state under the action of the elastic element, protecting the internal components of the body and meeting the needs of deep water use.

[0012] In one possible implementation, the sealing module further includes a cover plate connected to a support member, the cover plate and the support member forming a receiving cavity, and at least a portion of the sealing member being slidably disposed within the receiving cavity; an elastic member connecting the cover plate and the sealing member.

[0013] In the blocked state, one end of the elastic element can be connected to the cover plate, and the other end applies pressure to the blocking element, causing the blocking element to move towards the vent hole and seal the vent hole.

[0014] In one feasible approach, a conductive plate is provided on the support member, and a shape memory alloy component connects the conductive plate and the sealing component.

[0015] In some examples, it is necessary to apply voltage to the shape memory alloy component to cause it to deform upon heating. This requires the use of leads to electrically connect the shape memory alloy component to the power source. In this application, a conductive plate is provided and the shape memory alloy component is connected to the conductive plate. In this way, the leads can be connected to the conductive plate. Compared with connecting the leads directly to the shape memory alloy component, the connection method using the conductive plate is more convenient to implement.

[0016] In one possible implementation, the support has a sliding hole, and the sealing element includes a sliding post that is slidably disposed within the sliding hole to switch between a sealed state and an open state; a shape memory alloy element and a conductive plate are disposed within the sliding hole.

[0017] A sliding hole is made in the support component, and the sliding column of the sealing component can slide along the sliding hole, which can improve the smoothness of the movement of the sealing component; the shape memory alloy component and the conductive plate are set in the sliding hole, making full use of the space in the sliding hole and making the structure more compact.

[0018] In one possible implementation, the shape memory alloy component includes a shape memory alloy spring, one end of which is connected to a conductive plate and the other end to a sealing component, the extension direction of the shape memory alloy spring being parallel to the movement direction of the sealing component.

[0019] Memory alloy springs have a large range of extension and contraction, making it easier to switch between the blocked and open states.

[0020] In one possible implementation, the slide column has a mounting cavity, an elastic element is disposed within the mounting cavity, and a shape memory alloy element is sleeved on the outer periphery of the slide column.

[0021] In this example, an elastic element is placed inside the mounting cavity of the slide column, and a shape memory alloy element is fitted around the outer periphery of the slide column. For example, the elastic element can be a spring that can switch between a compressed state and a relaxed state. In the compressed state, the spring located in the mounting cavity can apply a thrust to the bottom wall of the slide column, causing the sealing element to move toward the vent and block the vent. When a voltage is applied to the shape memory alloy element, the shape memory alloy heats up and deforms, generating a thrust away from the vent, causing the sealing element to move away from the vent, allowing the vent to connect with the outside.

[0022] In one example, the elastic element includes a spring, one end of which abuts against the cover plate and the other end of which abuts against the bottom wall of the mounting cavity.

[0023] In one possible implementation, the sealing module also includes a sealing ring that is fitted over the outside of the conductive plate.

[0024] To prevent external water from entering the body of the instrument through the sliding holes, a sealing ring can be installed at the contact point between the conductive plate and the support.

[0025] In one possible implementation, the sealing element further includes a sealing plate; the sliding column includes a first sliding column and a second sliding column, which are connected to the sealing plate; the conductive plate includes a first conductive plate and a second conductive plate; the shape memory alloy component includes a first shape memory alloy component and a second shape memory alloy component, which connects the first conductive plate and the sealing plate, and the second shape memory alloy component connects the second conductive plate and the sealing plate.

[0026] In one possible implementation, the sealing plate is a conductor; a first conductive plate is used for electrical connection to a first voltage, and a second conductive plate is used for electrical connection to a second voltage, wherein the first voltage is greater than the second voltage.

[0027] In this way, the current transmission path is through the first conductive plate, the first shape memory alloy component, the sealing plate, the second shape memory alloy component, and the second conductive plate. When the current flows through the first shape memory alloy component and the second shape memory alloy component, the first shape memory alloy component and the second shape memory alloy component heat up and deform, supporting the sealing component and moving it away from the vent.

[0028] In one possible implementation, a first conductive plate is used to be electrically connected to a first voltage and a second voltage, and a second conductive plate is used to be electrically connected to a third voltage and a fourth voltage, wherein the first voltage is greater than the second voltage and the third voltage is greater than the fourth voltage.

[0029] For example, when a first piezoelectric and a second voltage are applied to the first conductive plate, the first conductive plate heats up. Since the first shape memory alloy component is connected to the first conductive plate, the heat from the first conductive plate is transferred to the first shape memory alloy component. The first shape memory alloy component heats up and deforms, applying a pushing force to the sealing component. Similarly, when a third piezoelectric and a fourth voltage are applied to the second conductive plate, the second conductive plate heats up. Since the second shape memory alloy component is connected to the second conductive plate, the heat from the second conductive plate is transferred to the second shape memory alloy component. The second shape memory alloy component heats up and deforms, applying a pushing force to the sealing component.

[0030] In one feasible approach, the conductive plate is connected to the support member via a snap-fit ​​structure, which includes a boss and a slot, one of which is disposed on the support member and the other on the conductive plate.

[0031] The conductive plate and support are connected by a snap-fit ​​structure, which not only simplifies the connection structure and saves space, but also makes assembly convenient.

[0032] Secondly, this application provides a watch body that can be used in wearable devices, such as watches or bracelets.

[0033] The table body provided in this application includes a blocking module of any of the above implementation methods, and the support component in the blocking module is the middle frame of the table body.

[0034] Since the body of this application includes the sealing module of the example above, the sealing component of the sealing module is usually in a normally closed state, that is, a normally closed sealing structure. Therefore, even in a water environment of 100 meters or even more than 200 meters, the sealing component is in a normally closed state under the action of the elastic component, protecting the internal components of the body and meeting the needs of deep water use.

[0035] In one possible implementation, the watch body also includes a waterproof and breathable component located on the side of the sealing component facing the interior of the watch body. The waterproof and breathable component is positioned opposite to the vent and is connected to the vent.

[0036] When sealed, the sealing element can fit against the waterproof and breathable element; when open, the sealing element can be moved away from the waterproof and breathable element.

[0037] Thirdly, this application provides a wearable device, which includes a watch strap and a watch body as described in any of the above implementations, with the watch body connected to the watch strap.

[0038] Since the wearable device of this application includes the sealing module of the example above, the sealing component of the sealing module is usually in a normally closed state, that is, a normally closed sealing structure. Therefore, even in a water environment of 100 meters or even more than 200 meters, the sealing component is in a normally closed state under the action of the elastic component, protecting the internal components of the device and meeting the needs of deep water use.

[0039] Fourthly, this application provides an electronic device, which includes a main body and a blocking module as described in any of the above implementations, the blocking module being mounted on the main body.

[0040] Since the electronic device contains the sealing module described above, which is a normally closed sealing structure, it remains in a normally closed state regardless of whether it is used on water or in aquatic environments. Therefore, even in water environments at depths of 100 meters or even 200 meters or more, the sealing component remains in a normally closed state under the action of the elastic element, protecting the internal components of the device and meeting the requirements for use in deep water.

Detailed Implementation

[0059] This application provides a wearable device, such as a smart bracelet or a smartwatch. The wearable device can be worn on the wrist and performs functions such as time display, time recording, time announcement, message notification, activity detection, heart rate monitoring, and blood oxygen level detection.

[0060] Wearable devices may include a strap and a body. The strap is used to wrap around the user's wrist to enable the wearable device to be worn, and the body is used for display.

[0061] Figure 1 illustrates an exemplary structural diagram of a wearable device. The wearable device 100 of the embodiment shown in Figure 1 is illustrated using a watch as an example. The wearable device 100 includes a watch body 200 and a watch strap 300. The watch body 200 and the watch strap 300 can be fixedly connected or detachably connected.

[0062] The watch body 200 can be round, rectangular, or other shapes. The watch body 200 may include a watch case 210 and a display screen 220.

[0063] The casing 210 and the display screen 220 enclose a receiving space. For example, as shown in FIG2, the receiving space can be used to accommodate various functional modules and electronic components of the wearable device 100, including but not limited to: processor 110, microphone 120, speaker 130, antenna 140, sensor 150, battery 160 and battery management module 170, memory 180 and barometer 190, etc.

[0064] Among them, microphone 120, speaker 130, antenna 140, sensor 150, battery 160, battery management module 170, memory 180, and barometer 190 are all electrically connected to processor 110.

[0065] The watch strap 300 may include a strap body and a connecting structure. Exemplarily, the strap body may include a first strap body and a second strap body. The material of the strap body may include, but is not limited to, metal, leather, rubber, ceramic, and nylon. The connecting structure can be used to connect the first strap body and the second strap body.

[0066] The connecting structure may include a buckle. The buckle may include a pin connected to the first strap body and a plurality of eyelets spaced apart along the length of the second strap body. The pin can be fixed to the eyelets, connecting the first and second strap bodies. It is understood that by adjusting the fixing of the pin to the eyelets at different positions, the tightness of the watch strap 300 can also be adjusted.

[0067] The connecting structure may include a butterfly clasp. The two ends of the butterfly clasp can be connected to a first strap body and a second strap body, respectively. When the butterfly clasp is folded and fastened, the first and second strap bodies are relatively close together to fit snugly against the user's wrist or other wearing area, securing the watch around the wrist; when the butterfly clasp is unfolded, the first and second strap bodies are relatively far apart, making it easier to remove the watch from the wrist.

[0068] The connection structure may include a magnetic clasp. For example, the magnetic clasp may include two magnetic tabs respectively disposed on a first strap body and a second strap body, the two magnetic tabs attracting each other to connect the first strap body and the second strap body. It is understood that by adjusting the position of the magnetic tabs, the tightness of the watch strap can also be adjusted.

[0069] The connection structure may include Velcro. For example, Velcro may be respectively disposed on a first strap body and a second strap body, and the two Velcro straps are glued together to connect the first strap body and the second strap body. It is understood that the tightness of the watch strap can be adjusted by adjusting the position of the Velcro straps.

[0070] In one example, for instance, microphone 120 needs to receive sound from outside the wearable device, so a microphone hole needs to be opened on the case; another example is that it is necessary to maintain the pressure difference between the inside and outside of the wearable device, so a pressure equalization hole can be opened on the case; yet another example is, as shown in Figure 2, since a barometer 190 is installed inside the case, a barometer hole needs to be opened on the case.

[0071] To prevent external water from entering the wearable device through the vents in the example described above, and to prevent water from damaging the electronic components inside the casing, a sealing element can be incorporated into some feasible designs.

[0072] The sealing element can switch between a sealed state and an open state. In the sealed state, the sealing element blocks the vent, and in the open state, the sealing element moves away from the vent. For example, when sound pickup is not needed, the sealing element can block the vent; when sound pickup is needed, the sealing element moves away from the vent, allowing the vent to connect with the outside of the device.

[0073] In some wearable devices, the waterproof rating of the sealing components is poor. For example, in high water depths (e.g., over 100 meters), the sealing effect of the sealing components is not good, making the wearable device unable to meet the needs of deep water use.

[0074] To improve waterproofing and meet the needs of users in various environments, such as deep water and high-pressure environments, this application provides some wearable devices with waterproofing functions.

[0075] As shown in Figure 3, Figure 3 is a structural diagram of a table body provided in an embodiment of this application. Figures 4 and 5 are cross-sectional views of point A in Figure 3, cut along Q1-Q2.

[0076] Figure 4 shows a cross-sectional view of the sealing component 1 when it blocks the vent 2101, i.e., the sealing component 1 is in the blocked state. Figure 5 shows a cross-sectional view of the sealing component 1 when it does not block the vent 2101, i.e., the sealing component 1 is in the open state.

[0077] In the wearable device provided in this embodiment, the watch case 210 includes a middle frame 210A and a cover plate 210B. A sealing member 1 is provided on the middle frame 210A, and a vent 2101 is provided on the middle frame 210A, which can connect the outside and inside of the watch case. For example, in the examples of Figures 4 and 5, two vents 2101 are arranged side by side, one of which can be a microphone hole, and the other can be an air pressure equalization hole.

[0078] The sealing component 1 is used to seal or open the vent 2101. In some examples, a waterproof vent 4 can also be provided on the middle frame 210A. The waterproof vent 4 is connected to the vent 2101 and can prevent external water from entering the watch case.

[0079] In the examples of Figures 4 and 5, the waterproof and breathable component 4 is located on the side of the vent 2101 near the outside of the watch case. The sealing component 1 can cooperate with the waterproof and breathable component 4. For example, when it is necessary to seal the vent 2101, the sealing component 1 can be attached to the waterproof and breathable component 4. When it is necessary to open the vent 2101, the sealing component 1 can be moved away from the waterproof and breathable component 4, and there is a gap between them, so that the vent 2101 communicates with the outside of the watch case.

[0080] The sealing element 1 provided in this application has a variety of possible structures. For example, Figures 4 and 5 show an example of one possible implementation of the sealing element 1.

[0081] See Figures 4 and 5. In this example, the sealing element 1 includes a sealing plate 11 and at least one sliding post 12, each sliding post 12 being connected to the sealing plate 11 and located on the side of the sealing plate 11 facing the inside of the case.

[0082] In some examples, multiple sliding posts 12 may be included; for example, multiple sliding posts 12 may be located on the sides of the waterproof and breathable component 4. As shown in the examples in Figures 4 and 5, two sliding posts 12 are illustrated, located on both sides of the waterproof and breathable component 4.

[0083] The sliding column 12 is set inside the sliding hole 2102, which is opened on the middle frame 210A. The extension direction of the sliding hole 2102 is parallel to the extension direction of the sealing component 1. The sliding hole 2102 can guide the movement of the sliding column 12. For example, the sliding column 12 moves along the X direction inside the sliding hole 2102, making the linear movement accuracy of the sliding column 12 higher.

[0084] In the examples shown in Figures 4 and 5, two sliding posts 12 are illustrated, which are connected to the same side of the sealing plate 11. Each sliding post 12 corresponds to a sliding hole 2102. In this way, the sealing plate 11 and the sliding posts 12 connected together can slide along the extension direction of the sliding hole 2102 under the action of force.

[0085] Multiple sliding pins 12 slide along corresponding sliding holes 2102. Multiple sliding pins 12 sliding along the holes can make the movement of the entire sealing component 1 more stable and balance the movement of the sealing component.

[0086] In some examples, the sealing plate 11 and the sliding column 12 can be integrally molded structural components, for example, they can be made by injection molding; or, the sealing plate 11 and the sliding column 12 are two independent structural components connected by a connecting structure, for example, the sealing plate 11 and the sliding column 12 can be connected by bolts or adhesive.

[0087] The sealing plate 11 and the sliding rod 12 can be made of rigid materials. The materials of the sealing plate 11 and the sliding rod 12 can be the same or different. For example, the sealing plate 11 and the sliding rod 12 can be metal parts.

[0088] In Figures 4 and 5, the cross-section of the sliding column 12 can be circular, and the cross-section of the sliding hole 2102 for sliding the sliding column 12 can also be circular. In other examples, the cross-section of the sliding column 12 can be rectangular, and the cross-section of the sliding hole 2102 for sliding the sliding column 12 can also be rectangular. In other instances, the cross-section of the sliding column 12 can also be other shapes, and this application does not impose any special limitations on the shape of the cross-section of the sliding column 12.

[0089] For example, the cross-section of the sliding column 12 is circular or rectangular, and the cross-section of the sliding hole 2102 is circular or rectangular. This can simplify the processing technology of the sliding column 12 and the hole, and also facilitate the assembly of other structural components, such as the elastic component 2 and the shape memory alloy component 3 mentioned below.

[0090] As shown in Figures 4 and 5, in some examples, the sealing component 1 may also include a plug 13, which is connected to the sealing plate 11 and is located on the side of the sealing plate 11 facing the waterproof and breathable component 4. For example, when the sealing component 1 seals the waterproof and breathable component 4, the plug 13 in the sealing component 1 can be used to seal the waterproof and breathable component 4.

[0091] Among the available materials, the plug 13 can be made of an elastic material, such as rubber, forming a rubber block. The elasticity of the rubber block can enhance the bonding strength between the plug 13 and the waterproof and breathable component 4, further improving the waterproof effect.

[0092] The sealing plate 11, sliding column 12 and plug 13 can be integrally formed structural components.

[0093] Alternatively, the sealing plate 11 and the plug 13 can be two independent structural components. For example, an installation groove can be opened on the sealing plate 11, and the plug 13 can be set in the installation groove through an adhesive layer.

[0094] Continuing with Figures 4 and 5, this example also includes an elastic element 2. As shown in Figure 4, the elastic element 2 connects the cover plate 210B and the sealing element 1. In the sealed state, the elastic element 2 provides a spring force to the sealing element 1 to move closer to the vent 2101. For example, in Figure 4, the elastic element 2 includes a spring, one end of which is connected to the cover plate 210B and the other end is connected to the sealing plate 11. The spring can be in a compressed state, which can apply a thrust F1 to the sealing plate 11, causing the plug 13 to fit against the waterproof and breathable element 4, thereby sealing the waterproof and breathable element 4.

[0095] Continuing with Figures 4 and 5, this example also includes a shape memory alloy component 3. As shown in Figure 5, the shape memory alloy component 3 connects the middle frame 210A and the sealing component 1. In the open state, the shape memory alloy component 3 provides a spring force to the sealing component 1 to move away from the vent 2101. For example, in Figure 5, the shape memory alloy component 3 includes a shape memory alloy spring, one end of which is connected to the middle frame 210A, and the other end is connected to the sealing plate 11. The shape memory alloy component 3 can deform when heated, for example, it can elongate when heated, and can apply the thrust F2 shown in Figure 5 to the sealing plate 11, so that the plug 13 moves away from the waterproof vent 4, realizing the communication between the waterproof vent 4 and the vent 2101 and the outside of the watch case.

[0096] As shown in Figure 4, when the vent 2101 is not required to connect with the outside of the watch case, no voltage is applied to the shape memory alloy 3, the shape memory alloy 3 does not deform, and does not exert force on the sealing component 1. In this state, the elastic component 2 can apply a pushing force F1 to the sealing component 1. Under the action of the pushing force F1, the sealing component 1 moves toward the waterproof and breathable component 4, so that the plug 13 fits onto the waterproof and breathable component 4, thereby sealing the vent 2101.

[0097] As shown in Figure 5, when the vent 2101 needs to be connected to the outside of the watch case (e.g., for making a call), a voltage is applied to the shape memory alloy 3. The shape memory alloy 3 heats up and deforms, generating a thrust F2 on the sealing component 1. The thrust F2 is greater than the thrust F1 generated by the elastic component 2. Consequently, under the action of the thrust F2, the sealing component 1 moves away from the waterproof and breathable component 4, creating a gap between the plug 13 and the waterproof and breathable component 4 to open the vent 2101.

[0098] This can be understood as follows: the sealing component 1 of this application is normally in a closed state, covering the waterproof and breathable component 4 and the vent 2101. In this way, even if the user of the wearable device washes their hands, takes a shower, or enters water, because the sealing component 1 is normally in a closed state under the action of the elastic component 3, external water will not enter the interior of the wearable device, thereby protecting the internal components of the device.

[0099] In addition, even in water environments at depths of 100 meters or even 200 meters or more, the sealing component 1 remains in a normally closed state under the action of the elastic component 3, meeting the requirements for use in deep water.

[0100] The shape memory alloy component 3 in this application example can be selected from at least one of nickel-titanium alloys, copper alloys, or iron alloys.

[0101] The shape memory alloy component 3 in this application example includes a shape memory alloy spring. The shape memory alloy spring has a large amount of extension and contraction, making it easier to switch the sealing component 1 between the sealing state and the open state, and the switching speed is also relatively fast.

[0102] There are multiple ways to cause the shape memory alloy part 3 to deform, and Figures 6 and 7 show two of these methods.

[0103] In Figure 6, a high voltage can be applied to one end of the shape memory alloy part 3 and a low voltage can be applied to the other end. For example, the first voltage can be a positive voltage and the second voltage can be a negative voltage.

[0104] In the example shown in Figure 6, there are two shape memory alloy components, namely a first shape memory alloy component 31 and a second shape memory alloy component 32. Voltages can be applied to the two ends of the first shape memory alloy component 31, for example, a first voltage and a second voltage can be applied to the two ends of the first shape memory alloy component 31, with the first voltage being greater than the second voltage. A third voltage and a fourth voltage can be applied to the two ends of the second shape memory alloy component 32, with the third voltage being greater than the fourth voltage. The first voltage and the third voltage can be positive voltages, for example, the first voltage and the third voltage can be equal. The second voltage and the fourth voltage can be negative voltages, for example, the second voltage and the fourth voltage can be equal.

[0105] In Figure 6, the sealing plate 11 can be a conductor or an insulator. For example, the sealing plate 11 can be a metal part or a plastic part.

[0106] In this example, by applying voltage to both ends of the first shape memory alloy 31, the first shape memory alloy 31 is deformed, generating a thrust on the sealing member 1. Similarly, by applying voltage to both ends of the second shape memory alloy 32, the second shape memory alloy 32 is deformed, generating a thrust on the sealing member 1. This causes the sealing member 1 to move smoothly away from the waterproof and breathable member 4, thereby opening the waterproof and breathable member 4.

[0107] In Figure 6, the current path is within the first shape memory alloy element 31, or the current path is within the second shape memory alloy element 21.

[0108] Figure 7 includes two shape memory alloy components, namely a first shape memory alloy component 31 and a second shape memory alloy component 32. A first voltage (such as a positive voltage) can be applied to the end of the first shape memory alloy component 31 that is connected to the middle frame 210A, and a second voltage (such as a negative voltage) can be applied to the end of the second shape memory alloy component 32 that is connected to the middle frame 210A. The first voltage is greater than the second voltage.

[0109] In this example, the sealing plate 1 is a conductor, for example, it can be a metal part, such as at least one of copper, aluminum, etc.

[0110] As shown in Figure 7, the current path in this example can be through the first shape memory alloy component 31, the sealing plate 11, and the second shape memory alloy component 32.

[0111] In the examples of Figures 6 and 7, one end of the first shape memory alloy component 31 or the second shape memory alloy component 32 can be connected to the sealing plate 11 by welding, and the other end can be connected to the watch case 210 by welding.

[0112] In some wearable devices, the power supply unit for powering the shape memory alloy component is located inside the watch case, which requires an electrical connection structure to electrically connect the shape memory alloy component to the power supply unit (such as a battery).

[0113] As shown in Figure 8, an electrical connection structure is provided, which includes a connecting wire 5. A through hole can be made in the case 210, through which the connecting wire 5 passes and connects to the shape memory alloy part 3.

[0114] To prevent external water from penetrating the perforation (see Figure 8), sealant 6 can be filled inside the perforation to improve waterproofing.

[0115] As shown in Figures 9 and 10, Figures 9 and 10 are cross-sectional views of point A in Figure 3, cut along Q1-Q2.

[0116] This example includes a vent 2101 formed on the middle frame 210A, a waterproof and breathable component 4 disposed opposite to the vent 2101, a sealing component 1 for sealing or opening the waterproof and breathable component 4, and also includes an elastic component 2 and a shape memory alloy component 3. Additionally, it includes a conductive plate 7 disposed on the middle frame 210A, and the shape memory alloy component 3 connects the conductive plate 7 and the sealing component 1.

[0117] The conductive plate 7 can be made of a metal material, such as at least one of copper or aluminum.

[0118] The conductive plate 7 can be positioned in various ways. In the examples of Figures 9 and 10, both the conductive plate 7 and the shape memory alloy part 3 are set inside the sliding hole 2102. The conductive plate 7 is located on the side of the sliding post 12 closer to the inside of the watch case. That is, the conductive plate 7 is closer to the inside of the watch case than the sliding post 12.

[0119] In some feasible ways, one end of the shape memory alloy part 3 can be welded to the conductive plate 7, and the other end can be welded to the sealing plate 11.

[0120] Figure 9 shows a cross-sectional view of the sealing component 1 when it seals the waterproof and breathable component 4, i.e., the sealing component 1 is in the sealed state. Figure 10 shows a cross-sectional view of the sealing component 1 when it does not seal the waterproof and breathable component 4, i.e., the sealing component 1 is in the open state.

[0121] As shown in Figure 9, in the blocked state, the elastic element 2 is used to give the blocking element 1 an elastic force F1 to move towards the vent 2101, so that the plug 13 fits against the waterproof and breathable element 4, thereby blocking the waterproof and breathable element 4.

[0122] As shown in Figure 10, in the open state, the shape memory alloy part 3 provides a spring force F2 to the sealing part 1 to move away from the vent 2101, so that the plug 13 moves away from the waterproof vent 4, thereby enabling the waterproof vent 4 and the vent 2101 to communicate with the outside world.

[0123] Since the conductive plate 7 is located inside the sliding hole 2102, in order to improve the sealing performance, as shown in Figures 9 and 10, a sealing ring 8 can be set at the position where the conductive plate 7 contacts the middle frame 210A. That is, the sealing ring 8 is fitted over the outside of the conductive plate 7 to achieve a sealed connection between the conductive plate 7 and the middle frame 210A.

[0124] When the conductive plate 7 is included, there are multiple ways to achieve the deformation of the shape memory alloy part 3. Some implementation examples are given below.

[0125] As shown in Figure 11, the system includes a first shape memory alloy component 31 and a second shape memory alloy component 32, as well as a first conductive plate 71 and a second conductive plate 72. The first shape memory alloy component 31 connects the first conductive plate 71 and the sealing plate 11, and the second shape memory alloy component 32 connects the second conductive plate 72 and the sealing plate 11. A first voltage (such as a positive voltage) can be applied to the first conductive plate 71, and a second voltage (such as a negative voltage) can be applied to the second conductive plate 72, wherein the first voltage is greater than the second voltage.

[0126] In this example, the sealing plate 1 is a conductor, for example, it can be a metal part.

[0127] As shown in Figure 11, the current path in this example can be through the first conductive plate 71, the first shape memory alloy component 31, the sealing plate 11, the second shape memory alloy component 32, and the second conductive plate 72.

[0128] As shown in Figure 12, high voltage and low voltage can be applied to the conductive plate, for example, positive voltage and negative voltage can be applied.

[0129] In the example of Figure 12, there are a first conductive plate 71 and a second conductive plate 72. Positive and negative voltages can be applied to the first conductive plate 71 and the second conductive plate 72.

[0130] When a first voltage and a second voltage are applied to the first conductive plate 71, the first voltage is greater than the second voltage, and the first conductive plate 71 heats up. The heat generated by the first conductive plate 71 can be transferred to the first shape memory alloy 31, which induces the first shape memory alloy 31 to deform and generate a thrust on the sealing plate 11.

[0131] Similarly, when a third voltage and a fourth voltage are applied to the second conductive plate 72, the third voltage is greater than the fourth voltage, and the second conductive plate 72 heats up. The heat generated by the second conductive plate 72 can be transferred to the second shape memory alloy 32, which induces the second shape memory alloy 32 to deform and generate a thrust on the sealing plate 11.

[0132] The conductive plate 3 can be made of metal, such as at least one of copper, aluminum, iron, etc. Metals have high thermal conductivity and are durable.

[0133] In some examples, a resistance wire can be placed inside the conductive plate 3 to increase the heat dissipation of the conductive plate 3, so that the shape memory alloy part can receive more heat in a short time, deform quickly, and support the sealing part.

[0134] In Figure 12, the sealing plate 11 can be a conductor or an insulator. For example, the sealing plate 11 can be a metal part or a plastic part.

[0135] In the example shown in Figure 11, by applying a voltage to the conductive plate, current can flow through the shape memory alloy component, causing it to heat up and deform. However, in the example shown in Figure 12, by applying a voltage to the conductive plate, the conductive plate heats up and transfers the heat to the shape memory alloy component, causing it to heat up and deform. In other words, the principles by which the conductive plate heats up and deforms are different in the two examples: one uses current to raise the temperature, and the other uses heat transfer.

[0136] In the example of Figure 12, the shape memory alloy part deforms due to heat transfer. In order to reduce the heat diffusion transferred to the shape memory alloy part, the sealing part 1 in Figure 12 can be made of a material with a low thermal conductivity, such as rubber.

[0137] In some wearable devices, the power supply unit for powering the shape memory alloy component is located inside the watch case, which requires an electrical connection structure to electrically connect the shape memory alloy component to the power supply unit (such as a battery).

[0138] As shown in Figure 13, Figure 13 illustrates an electrical connection structure for supplying power to a shape memory alloy component. The electrical connection structure includes a connecting wire 5, which is connected to a conductive plate 7.

[0139] Since the conductive plate 7 is located close to the inside of the body, it is connected to the conductive plate 7 by a connecting line 5. In the implementation process, the connection between the connecting line 5 and the conductive plate 7 is simpler, and the routing of the connecting line 5 can be more flexible.

[0140] Figure 14 shows an exploded view of the casing structure of a wearable device.

[0141] The wearable device's casing 210 may include a mid-frame 210A and a decorative cover 210B. Figure 14 shows a portion of the mid-frame 210A. The mid-frame 210A and the decorative cover 210B are fixedly connected, for example, by a threaded connector or by a snap-fit ​​structure. It is understood that the decorative cover 210B may also be referred to by other names, such as cover plate 210B.

[0142] The decorative cover 210B has a through hole 210B1 for communicating with the interior of the watch case. For example, sound can be transmitted to the interior of the watch case through this through hole 210B1. The through hole 210B1 can be located on the side of the decorative cover 210B.

[0143] The middle frame 210A and the decorative cover 210B form a receiving cavity, and at least a portion of the sealing member 1 is slidably disposed within the receiving cavity. For example, the sealing plate 11 of the sealing member 1 is slidably disposed within the receiving cavity.

[0144] An installation cavity 121 can be formed in the sliding column 12 of the sealing member 1, and the installation cavity 121 passes through the sealing plate 11. The elastic member 2 is disposed in the installation cavity 121. One end of the elastic member 2 is connected to the bottom wall of the installation cavity 121. For example, one end of the elastic member 2 abuts against the bottom wall of the installation cavity 121. The other end of the elastic member 2 is connected to the decorative cover 210B. For example, the other end of the elastic member 2 abuts against the decorative cover 210B.

[0145] By placing the elastic element 2 inside the mounting cavity 121, the direction of extension and retraction of the elastic element 2 can be limited, thereby allowing the sealing element 1 to move along a straight line.

[0146] Continuing with Figure 14, a sliding hole 2102 is provided on the middle frame 210A. The sliding post 12 is slidably disposed within the sliding hole 2102. Furthermore, the radial dimension of the sliding hole 2102 is larger than the radial dimension of the sliding post 12. In this way, the shape memory alloy part 3 can be disposed within the sliding hole 2102 and fitted outside the sliding post 12. That is, in this embodiment, the elastic element 2 is disposed inside the sliding post 12, and the shape memory alloy part 3 is fitted outside the sliding post 12. The sliding post 12 is slidably disposed within the sliding hole 2102. The elastic element 2 and the shape memory alloy part 3 are distributed along the radial direction of the sliding post 12, making full use of the space within the sliding hole 2102.

[0147] The conductive plate 7 and the sealing ring 8 are disposed in the sliding hole 2102. Figure 15 shows one way of fixing the conductive plate 7, and Figure 16 shows a structural diagram of the conductive plate 7.

[0148] As shown in Figure 15, the middle frame 210A has a boss 2103 near the inside of the case. The boss 2103 extends into the sliding hole 2102. As shown in Figure 16, the conductive plate 7 has a groove 701 that mates with the boss 2103. The boss 2103 is set in the groove 701 to achieve a fixed connection between the conductive plate 7 and the middle frame 210A.

[0149] In the example of Figure 15, the cover plate 210B covers the sealing member 1. When the sealing member 1 switches between the sealing state and the open state, the sealing member 1 moves relative to the cover plate 210B. The cover plate 210B can protect the moving sealing member 1 and prevent the sealing member 1 from being exposed. When the external structure touches the sealing member 1, the sealing member 1 will fail.

[0150] In some examples, the cover plate 210B is an insulator, while the sealing plate 11 of the sealing element 1 is a conductor. This allows the cover plate 210B to provide protection against electric shock when current flows through the sealing plate 11. In other examples, the cover plate 210B can be fixedly connected to the sealing element 1, and the cover plate 210B and the sealing element 1 can move together to switch between a sealed state and an open state.

[0151] In the structure shown in Figure 14, the shape memory alloy component 3 can be understood as being fitted around the elastic component 2. When the cover plate 210B can be fixedly connected to the sealing component 1, and the cover plate 210B and the sealing component 1 move together, the shape memory alloy component 3 and the elastic component 2 can be arranged side by side, for example, side by side along the Y direction of Figure 13.

[0152] As shown in Figure 17, Figure 17 is a cross-sectional view of point A in Figure 3, cut along Q1-Q2.

[0153] This example demonstrates another arrangement of the elastic element 2 and the shape memory alloy element 3. The sliding column 12 has a mounting cavity 121, and both the elastic element 2 and the shape memory alloy element 3 are disposed within the mounting cavity 121. For example, a partition 122 can be disposed within the mounting cavity 121, dividing the mounting cavity 121 into a first chamber and a second chamber. The first chamber is close to the cover plate 210B, and the second chamber is close to the conductive plate 7. The elastic element 2 is disposed within the first chamber, with one end connected to the cover plate 210B and the other end connected to the partition 122. The shape memory alloy element 3 is disposed within the second chamber, with one end connected to the partition 122 and the other end connected to the conductive plate 7.

[0154] In the example of Figure 17, since the elastic element 2 and the shape memory alloy element 3 are stacked along the depth dimension of the sliding hole 2102, the radial dimension of the sliding hole 2102 can be compressed. This increases the area of ​​the waterproof and breathable element 4. For example, in Figure 17, since there are many vents 2101, a larger area of ​​waterproof and breathable element 4 is required. This can be achieved by stacking the elastic element 2 and the shape memory alloy element 3 along the depth dimension of the sliding hole 2102. This results in a larger area of ​​waterproof and breathable element 4 that covers more of the vents 2101.

[0155] The sealing element 1, elastic element 2, and shape memory alloy element 3 of this application example can be disposed on the mid-frame 201A of the wearable device described above. In other implementations, they can also be disposed on other support elements to form a sealing module. This sealing module can be disposed on the body of other electronic devices, such as wearable devices, glasses, or physiological monitoring instruments. The body can be the frame or temple of glasses, or the housing of a physiological monitoring instrument, etc.
