Description

Technical Field

[0001] This application relates to the field of electronic technology, and more particularly to a detection device and an electronic device. Background Technology

[0002] Electrocardiogram (ECG) information and bioelectrical impedance analysis (BIA) are fundamental physiological characteristics of the human body, and these physiological signs can provide insights into a person's health status. To achieve intelligent detection of these physiological characteristics, current electronic devices such as watches and wristbands can incorporate detection devices. These devices include electrodes that come into contact with the user to collect electrical signals related to the user's physiological characteristics, and then detect the user's physiological characteristics based on these signals.

[0003] To prevent the metal casing of electronic devices from interfering with the normal operation of the electrodes in the detection device, it is necessary to ensure that the electrodes and the metal casing are insulated. However, current insulation solutions are difficult to balance insulation reliability and drop resistance under various application scenarios, resulting in poor electrode performance. Utility Model Content

[0004] Some embodiments of this application provide a detection device and electronic device to solve the problem of difficulty in balancing insulation reliability and drop resistance performance in various application scenarios. The following describes this application from multiple aspects, and the embodiments and beneficial effects of the following aspects can be referred to each other.

[0005] In a first aspect, embodiments of this application provide a detection device, comprising: a first metal member, a first insulating member, and an electrode. The first metal member includes a groove structure with its opening facing a first direction. The first insulating member includes a first portion and / or a second portion. The first portion covers the inner sidewall of the groove structure, and the second portion surrounds the groove structure circumferentially and covers at least a portion of the outer sidewall of the groove structure. The electrode is located within the cavity of the groove structure, and a second insulating member is provided between the electrode and the bottom wall of the groove structure. The sidewall of the groove structure protrudes from the electrode along the first direction.

[0006] The aforementioned detection device, on the one hand, protects the electrode and improves its drop resistance by placing the electrode within the cavity of the groove structure of the first metal component and making the sidewall of the groove structure protrude from the electrode along a first direction. This eliminates limitations on the electrode's structural form and broadens its applicability. For example, in applications where the electrode is a glass electrode, when the detection device falls to the ground, the sidewall of the groove structure can contact the ground before the electrode. In other words, the impact force acts on the sidewall of the groove structure, not on the electrode, thus protecting the electrode and preventing it from breaking.

[0007] On the other hand, the first insulating component can achieve reliable insulation between the electrode and the metal casing of the electronic device containing the detection device, preventing conduction between the electrode and the metal casing of the electronic device in various application scenarios. These application scenarios include water ingress (e.g., handwashing, bathing, swimming, rain, and diving), dirt, or prolonged use.

[0008] For example, in some embodiments, the first insulating member may include a first portion, such that the first portion can provide insulation between the electrode and the sidewalls of the groove structure of the first metal member, and also between the electrode and the bottom wall of the groove structure. Therefore, the electrode and the first metal member are insulated from each other. Furthermore, after the electrode is mounted in the electronic device via the first metal member, the electrode is insulated from the metal casing of the electronic device.

[0009] For example, in some other embodiments, the first insulating element may also include a second part. After the electrode is mounted in the electronic device through the first metal element, the second part can achieve insulation between the first metal element and the metal casing of the electronic device, thereby ensuring that the electrode and the metal casing are insulated.

[0010] For example, in some other embodiments, the first insulating element may also include a first part and a second part. After the electrode is installed in the electronic device through the first metal part, the electrode and the first metal part are insulated from each other, and the first metal part is also insulated from the metal casing of the electronic device. This can further improve the insulation reliability between the electrode and the metal casing.

[0011] In one possible implementation of the first aspect described above, the first insulating member includes a first portion. A first through hole is formed in the bottom wall of the groove structure, penetrating the bottom wall of the groove structure along a first direction. A first groove is formed at the connection end between the inner bottom wall and the inner sidewall of the groove structure, and the first groove surrounds the first through hole. The first insulating member also includes a third portion, which is connected to the first portion along the first direction and fills the first groove.

[0012] According to embodiments of this application, the first through-hole can be understood as the inner cavity of the detection device, used to accommodate structural components of the detection device. In some embodiments, after the detection device is installed in an electronic device, the first through-hole can communicate with the inner cavity of the electronic device.

[0013] By setting a first groove and filling the third part of the first insulating member into the first groove, it can be ensured that the first joint between the groove structure and the first insulating member will not directly communicate with the first through hole, but will be separated by the groove structure. Therefore, liquids (e.g., water) outside the detection device are unlikely to seep into the first through hole or the inner cavity of the electronic device where the detection device is located along the first joint, thereby preventing the structural components in the first through hole and the inner cavity of the electronic device from being damaged by moisture, and effectively improving the sealing and waterproof performance of the detection device.

[0014] It should be noted that the first joint refers to the boundary area between the groove structure and the first insulating component, and is not a gap or opening in the physical sense. In fact, in some cases, the first joint may not be visible to the naked eye.

[0015] In one possible implementation of the first aspect described above, the third part protrudes from the first part along a second direction, the second direction being perpendicular to the first direction, and pointing from the outside of the groove structure to the inside of the groove structure.

[0016] This makes it easier to install a seal to seal the first joint between the groove structure and the first insulating element, thereby further improving the sealing and waterproof performance of the detection device.

[0017] In one possible implementation of the first aspect described above, the inner bottom wall of the groove structure is flush with the first surface of the third part facing the first direction.

[0018] In this way, the difficulty of setting and sealing the seal can be reduced. The seal can cover part of the inner bottom wall and the first surface of the third part relatively smoothly to seal the first joint between the groove structure and the first insulating element, thereby further improving the sealing and waterproof performance of the detection device.

[0019] In one possible implementation of the first aspect described above, the second insulating member covers the inner bottom wall of the groove structure and a portion of the first surface of the third part facing the first direction. This eliminates the need for additional sealing members to seal the first joint between the groove structure and the first insulating member, reducing the number of components and simplifying the overall structure.

[0020] In one possible implementation of the first aspect described above, the second insulating element is an insulating adhesive. Thus, the second insulating element can also achieve a fixed connection between the electrode and the bottom wall of the groove structure, preventing the electrode from detaching from the groove structure.

[0021] In one possible implementation of the first aspect described above, the first insulating member includes a second portion. Furthermore, the bottom wall of the groove structure has a through hole that penetrates the bottom wall of the groove structure along a first direction. The outer wall of the groove structure includes a first annular region and a second annular region connected along the first direction, both extending circumferentially along the groove structure. The first annular region is located at one end of the outer wall facing away from the first direction. The second portion covers the second annular region, and the first end of the second annular region is recessed relative to the first annular region along a second direction. The first end is the end of the second annular region closer to the first annular region along the first direction. The second direction is perpendicular to the first direction and extends from the outside of the groove structure towards the inner cavity of the groove structure.

[0022] According to embodiments of this application, the first through-hole can be understood as the inner cavity of the detection device, used to accommodate structural components of the detection device. In some embodiments, after the detection device is installed in an electronic device, the first through-hole can communicate with the inner cavity of the electronic device.

[0023] By setting the first annular region and the second annular region, it can be ensured that the first joint between the groove structure and the first insulating component extends to the outer wall of the groove structure. Therefore, liquids (e.g., water) outside the detection device are unlikely to seep into the first through hole or the inner cavity of the electronic device where the detection device is located along the first joint. This prevents structural components in the first through hole and the inner cavity of the electronic device from being damaged by moisture, effectively improving the sealing and waterproof performance of the detection device. At the same time, it also facilitates the setting of a sealing component to seal the first joint, effectively reducing the difficulty of sealing the first joint.

[0024] In one possible implementation of the first aspect described above, the detection device further includes a sealing ring, which is fitted over the outer side of the second portion and the second annular region.

[0025] According to the embodiments of this application, on the one hand, the sealing ring can seal the gap between the detection device and the metal casing of the electronic device in which it is located; on the other hand, the sealing ring can also seal the first joint between the groove structure and the first insulating member, thereby realizing the functional reuse of the sealing ring, reducing the number of components of the detection device, and making the overall structure of the detection device simpler.

[0026] In one possible implementation of the first aspect described above, the outer wall of the groove structure further includes a third annular region extending circumferentially along the groove structure, with the first, second, and third annular regions arranged sequentially along a first direction. The second end of the second annular region is recessed along a second direction relative to the third annular region, and this second end is the end of the second annular region closest to the third annular region along the first direction.

[0027] When the detection device is installed in an electronic device, the third annular area can be located on the outer surface of the electronic device. The material of the third annular area is metal, so that when the electronic device is dropped, the third annular area can withstand greater drop impact, thereby further improving drop resistance.

[0028] In one possible implementation of the first aspect described above, the first insulating element includes at least one of a first plastic element and a first sealant.

[0029] In one possible implementation of the first aspect described above, the first metal member and the first insulating member together constitute a support, and at least one of insulating ink and air is provided between the support and the side of the electrode.

[0030] In one possible implementation of the first aspect described above, the first insulating element includes a first plastic element, and the first plastic element and the first metal element are integrally formed.

[0031] By making the first metal part and the first plastic part an integral structure, the number of parts of the detection device can be effectively reduced, the assembly efficiency of the detection device can be improved, and the bonding between the first metal part and the first plastic part can be made tighter, thereby further improving the sealing and waterproof performance.

[0032] In one possible implementation of the first aspect described above, the thickness of the first plastic part can be greater than or equal to 0.2 mm, for example, 0.2 mm, 0.3 mm, 0.4 mm, or 0.5 mm, so that the first plastic part can have a better insulation effect. The thickness of the first plastic part is the dimension of the first plastic part along the second direction.

[0033] In one possible implementation of the first aspect described above, the first insulating member includes a first sealant, which fills the space between the inner wall of the groove structure and the electrode. Furthermore, the inner wall of the groove structure and the electrode include a first gap and a second gap, the first gap and the second gap being disposed along a first direction, and the width of the first gap being greater than the width of the second gap. The width of the first gap is the dimension of the first gap along a second direction, and the width of the second gap is the dimension of the second gap along the second direction, the second direction being perpendicular to the first direction.

[0034] In this way, the first sealant can be effectively guided to fully fill the space between the inner wall of the groove structure and the electrode, thereby further enhancing the insulation effect between the groove structure and the electrode.

[0035] In one possible implementation of the first aspect described above, the bottom surface of the electrode includes a first conductive layer, the top surface of the electrode includes a second conductive layer, the top surface of the electrode faces away from the bottom wall of the groove structure, the bottom surface of the electrode faces the bottom wall of the groove structure, a conductive via is formed on the electrode, the conductive via penetrates the electrode along a first direction, and the first conductive layer and the second conductive layer are electrically connected through the conductive via.

[0036] In this way, the first conductive layer and the second conductive layer can transmit signals through conductive vias without transmitting signals through the side of the electrode. Thus, the conductive layer on the side of the electrode can be insulated from the first conductive layer and the second conductive layer, or the side of the electrode can be made insulated to ensure that the contact between the side of the electrode and the first metal part does not affect the signal transmission effect between the first conductive layer and the second conductive layer.

[0037] In one possible implementation of the first aspect described above, the bottom surface of the electrode includes a first conductive layer, the top surface of the electrode includes a second conductive layer, the top surface of the electrode faces away from the bottom wall of the groove structure, the bottom surface of the electrode faces the bottom wall of the groove structure, and the side surface of the electrode includes a third conductive layer. The first and second conductive layers are electrically connected through the third conductive layer. The ratio between the area of ​​the third conductive layer and the area of ​​the side surface of the electrode is 0.001 to 0.1, for example, 0.001, 0.002, 0.003, 0.004, 0.005, 0.006, or 0.007. That is, only a portion of the side surface of the electrode is conductive, which effectively reduces the risk of the side surface of the electrode becoming conductive with the first metal component, resulting in better insulation reliability between the electrode and the support.

[0038] In one possible implementation of the first aspect described above, the first conductive layer and the second conductive layer are electrically connected via a conductive via, and the side of the electrode includes a fourth conductive layer, with the first and second conductive layers respectively insulated from the fourth conductive layer. Thus, even if the fourth conductive layer is conductive to the first metal component, the signal transmission between the first and second conductive layers will not be affected, thereby ensuring the electrode can function normally.

[0039] In one possible implementation of the first aspect described above, the ratio between the area of ​​the first conductive layer and the area of ​​the bottom surface of the electrode is 0.01 to 0.5, for example, 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, or 0.07. That is, only a portion of the bottom surface of the electrode is conductive. This effectively reduces the risk of conductivity between the bottom surface of the electrode and the first metal component, resulting in better insulation reliability between the electrode and the first metal component.

[0040] Secondly, embodiments of this application provide a detection device, which includes a second metal member, a third insulating member, and an electrode. The third insulating member has a frame-shaped structure, and the second metal member and the third insulating member are stacked along a first direction, together forming a receiving cavity. The electrode is located in the receiving cavity, and a fourth insulating member is provided between the electrode and the second metal member. The third insulating member protrudes from the electrode along the first direction.

[0041] The aforementioned detection device, on the one hand, by placing the electrode within a cavity formed by the second metal component and the third insulating component, and ensuring that the third insulating component protrudes from the electrode along a first direction, can protect the electrode and improve its drop resistance. This removes limitations on the electrode's structural form and broadens its applicability. For example, in applications where the electrode is a glass electrode, when the detection device falls to the ground, the third insulating component can contact the ground before the electrode. This means the impact force acts on the third insulating component, not the electrode, thus protecting the electrode and preventing breakage. Furthermore, due to the support of the second metal component, the third insulating component will not undergo significant deformation, effectively protecting the electrode.

[0042] On the other hand, by setting a third and a fourth insulating component on the second metal component, reliable insulation between the electrode and the second metal component can be achieved, thereby achieving reliable insulation between the electrode and the metal casing of the electronic device where the detection device is located, preventing conduction between the electrode and the metal casing of the electronic device in various application scenarios. These application scenarios include water ingress (e.g., handwashing, bathing, swimming, rain, and diving), dirt accumulation, or prolonged use.

[0043] In one possible implementation of the second aspect described above, a second through hole is provided on the second metal part, the second through hole penetrates the second metal part along the first direction, a second groove is provided at the connection end between the second surface of the second metal part facing the first direction and the third insulating part, the second groove surrounds the second through hole, and the third insulating part includes a fourth part and a fifth part connected along the first direction, the fourth part fills the second groove, and the fifth part is located outside the second groove.

[0044] According to embodiments of this application, the second through hole can be understood as the inner cavity of the detection device, used to accommodate structural components of the detection device. In some embodiments, after the detection device is installed in an electronic device, the second through hole can communicate with the inner cavity of the electronic device.

[0045] By setting a second groove and filling the fourth part of the third insulating member into the second groove, it can be ensured that the second joint between the second metal member and the third insulating member will not directly communicate with the second through hole, but will be separated by the second metal member. Therefore, liquids (e.g., water) outside the detection device are unlikely to seep into the second through hole or the inner cavity of the electronic device where the detection device is located along the second joint, thereby preventing the structural components in the second through hole and the inner cavity of the electronic device from being damaged by moisture, and effectively improving the sealing and waterproof performance of the detection device.

[0046] It should be noted that the second seam refers to the boundary area between the second metal part and the third insulating part, and is not a gap or opening in the physical sense. In fact, in some cases, the second seam may not be visible to the naked eye.

[0047] In one possible implementation of the second aspect described above, the fourth portion protrudes from the fifth portion along a second direction perpendicular to the first direction and pointing from the outside of the receiving cavity to the receiving cavity.

[0048] This makes it easier to install a seal to seal the second joint between the second metal part and the third insulating part, thereby further improving the sealing and waterproof performance of the detection device.

[0049] In one possible implementation of the second aspect described above, the third surface of the fourth part facing the first direction is flush with the second surface of the second metal part.

[0050] In this way, the difficulty of setting and sealing the seal can be reduced. The seal can cover part of the second and third surfaces relatively smoothly to seal the second joint between the second metal part and the third insulating part, thereby further improving the sealing and waterproof performance of the detection device.

[0051] In one possible implementation of the second aspect described above, the fourth insulating member covers a portion of the second surface of the second metal member and a portion of the third surface of the fourth part. This eliminates the need for additional sealing members to seal the second joint between the second metal member and the third insulating member, reducing the number of components and simplifying the overall structure.

[0052] In one possible implementation of the second aspect described above, the fourth insulating element is an insulating adhesive. Thus, the fourth insulating element can also achieve a fixed connection between the electrode and the first metal part, preventing the electrode from detaching from the first metal part.

[0053] In one possible implementation of the second aspect described above, at least one of insulating ink and air is provided between the third insulating member and the side of the electrode.

[0054] In one possible implementation of the second aspect above, the third insulating element comprises the second plastic element, or the third insulating element comprises the second plastic element and the second sealant.

[0055] In one possible implementation of the second aspect described above, the third insulating element includes a second plastic element, which is integral with the second metal element.

[0056] By making the second metal part and the second plastic part an integral structure, the number of parts of the detection device can be effectively reduced, the assembly efficiency of the detection device can be improved, and the bond between the second metal part and the second plastic part can be made tighter, thereby further improving the sealing and waterproof performance.

[0057] In one possible implementation of the second aspect described above, the third insulating member includes a second plastic member and a second sealant. The second plastic member surrounds the electrode, and the second sealant fills the space between the second plastic member and the electrode. A third gap and a fourth gap are provided between the second plastic member and the electrode. The third gap and the fourth gap are disposed along a first direction, and the width of the third gap is greater than the width of the fourth gap. The width of the third gap is the dimension of the third gap along a second direction, and the width of the fourth gap is the dimension of the fourth gap along a second direction. The second direction is perpendicular to the first direction.

[0058] In this way, the second sealant can be effectively guided to fully fill the space between the second plastic part and the electrode, thereby further enhancing the insulation effect between the second plastic part and the electrode.

[0059] In one possible implementation of the second aspect described above, the thickness of the second plastic part can be greater than or equal to 0.2 mm, for example, 0.2 mm, 0.3 mm, 0.4 mm, or 0.5 mm, so that the second plastic part can have a better insulation effect. The thickness of the second plastic part is the dimension of the first plastic part along the second direction.

[0060] In one possible implementation of the second aspect above, the bottom surface of the electrode includes a first conductive layer, the top surface of the electrode includes a second conductive layer, the top surface of the electrode faces away from the second metal part, the bottom surface of the electrode faces the second metal part, a conductive via is formed on the electrode, the conductive via penetrates the electrode along a first direction, and the first conductive layer and the second conductive layer are electrically connected through the conductive via.

[0061] In this way, the first conductive layer and the second conductive layer can transmit signals through conductive vias without transmitting signals through the side of the electrode. Thus, the conductive layer on the side of the electrode can be insulated from the first conductive layer and the second conductive layer, or the side of the electrode can be made insulated to ensure that the contact between the side of the electrode and the second plastic part does not affect the signal transmission effect between the first conductive layer and the second conductive layer.

[0062] In one possible implementation of the second aspect described above, the bottom surface of the electrode includes a first conductive layer, the top surface of the electrode includes a second conductive layer, the top surface of the electrode faces away from the second metal part, the bottom surface of the electrode faces the second metal part, and the side surface of the electrode includes a third conductive layer. The first conductive layer and the second conductive layer are electrically connected through the third conductive layer. The ratio between the area of ​​the third conductive layer and the area of ​​the side surface of the electrode is 0.001 to 0.1, for example, 0.001, 0.002, 0.003, 0.004, 0.005, 0.006, or 0.007. That is, only a portion of the side surface of the electrode is conductive, which effectively enhances the insulation effect.

[0063] In one possible implementation of the second aspect described above, the first conductive layer and the second conductive layer are electrically connected via conductive vias, and the side of the electrode includes a fourth conductive layer, with the first and second conductive layers respectively insulated from the fourth conductive layer. In this way, the conductivity of the fourth conductive layer does not affect the signal transmission between the first and second conductive layers, thereby ensuring that the electrode can function normally.

[0064] In one possible implementation of the second aspect described above, the ratio between the area of ​​the first conductive layer and the area of ​​the bottom surface of the electrode is 0.01 to 0.5, for example, 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, or 0.07. That is, only a portion of the bottom surface of the electrode is conductive. This effectively reduces the risk of conductivity between the bottom surface of the electrode and the second metal component, resulting in better insulation reliability between the electrode and the second metal component.

[0065] Thirdly, embodiments of this application provide an electronic device, which includes a metal casing and a detection device as described in the first aspect, any possible implementation of the first aspect, the second aspect, and any possible implementation of the second aspect, wherein the detection device is mounted on the metal casing.

[0066] It should be understood that the beneficial effects of the third aspect mentioned above can be referred to the descriptions of the first and second aspects mentioned above, and will not be repeated here. Attached Figure Description

(Reference) Figure 1A and Figure 1B The electronic device 1 may include a detection device 10, a middle frame 20, a back cover 30, a display screen 40, and two watch straps 50.

[0110] To facilitate understanding, the following description, in conjunction with the attached diagram, will first introduce the middle frame 20, back cover 30, display screen 40, and two watch straps 50.

[0111] The middle frame 20 is generally frame-shaped. The back cover 30 and the display screen 40 are respectively installed on opposite sides of the middle frame 20. The middle frame 20, the back cover 30 and the display screen 40 together form the inner cavity of the electronic device 1 (not shown). The inner cavity of the electronic device 1 can accommodate the electronic components of the electronic device 1, such as circuit boards, chips and batteries.

[0112] In some embodiments, the middle frame 20 and the back cover 30 can be a single integrated structure, eliminating the need for subsequent assembly of the middle frame 20 and the back cover 30. That is, the structure formed by the middle frame 20 and the back cover 30 is a single, indivisible whole, rather than assembled from multiple physically independent components. In other words, the middle frame 20 and the back cover 30 are integrally molded. Alternatively, in other alternative embodiments, the middle frame 20 and the back cover 30 can also be separate structures. For example, the middle frame 20 and the back cover 30 can be molded separately and then assembled together. This application does not impose specific limitations on this.

[0113] It should be noted that in the above embodiments, the middle frame 20 and the back cover 30 can together constitute the housing of the electronic device 1, but this application is not limited to this. For example, in other embodiments, the housing of the electronic device 1 may also include a bezel 60 (or front cover), which is located on the front of the electronic device 1 and is used to fix the display screen 40. When the electronic device 1 is a watch or a bracelet, the housing of the electronic device 1 may also be referred to as a watch case.

[0114] In some embodiments, at least a portion of the housing of the electronic device 1 may be made of metal, such as aluminum alloy, stainless steel, or titanium alloy. Therefore, this portion of the housing may also be referred to as the metal casing of the electronic device 1. For example, any one or more of the middle frame 20, back cover 30, and bezel 60 may be made of metal, and correspondingly, any one or more of the middle frame 20, back cover 30, and bezel 60 constitute the metal casing of the electronic device 1.

[0115] Two watch straps 50 are connected to opposite sides of the mid-frame 20, and the two watch straps 12 are detachably locked to each other, so that the electronic device 1 can be worn on the user's wrist. When the electronic device 1 is worn on the user's wrist, the back cover 30 fits against the user's wrist, and the display screen 40 faces away from the user's wrist.

[0116] Understandable, Figure 1A and Figure 1B In the illustrated embodiment, the middle frame 20 and the bezel 60 are generally circular in shape, and correspondingly, the back cover 30 and the display screen 40 are generally circular in shape. In other embodiments, the middle frame 20 and the bezel 60 may also be rectangular or other irregularly shaped frame structures, and correspondingly, the back cover 30 and the display screen 40 may also be rectangular or other irregularly shaped structures. This application does not impose any limitations on these aspects.

[0117] Continue to refer to Figure 1A and Figure 1B To detect electrocardiogram (ECG) information, the detection device 10 of the electronic device 1 may include three ECG electrodes, namely electrode E1, electrode E2, and electrode E3. Electrode E1 is mounted on the middle frame 20, and electrodes E2 and E3 are mounted on the rear cover 30.

[0118] Taking electrode E1 as an example, in some embodiments, the material of electrode E1 can be metal, and electrode E1 can be referred to as a metal electrode. Alternatively, in some other alternative embodiments, electrode E1 may also include a substrate and a conductive layer disposed on the substrate, and the material of the substrate may be, for example, glass. When the material of the substrate of electrode E1 is glass, electrode E1 can also be referred to as a glass electrode.

[0119] It is understood that the structures of electrodes E2 and E3 are essentially the same as those of electrode E1. Therefore, the description of electrode E1 above can be referred to, and will not be repeated here.

[0120] When a user touches electrodes E1, E2, and E3, electrical conductivity is established between the user's skin and electrodes E1, E2, and E3, enabling the detection of electrocardiogram (ECG) information. For example, a user can wear the electronic device 1 on their left wrist, allowing electrodes E2 and E3 on the back cover 30 to fit against the user's wrist. The user can then touch electrode E1 on the middle frame 20 with their right fingers. At this point, an ECG lead channel is formed between the user's left and right hands, allowing the acquisition of electrical signals related to the user's ECG information. Processing these signals yields the user's ECG data.

[0121] Continue to refer to Figure 1A and Figure 1BIn some embodiments of this application, the detection device 10 can function as a button on the electronic device 1, and the electrode E1 can function as the keycap of the button, used to withstand pressing pressure and contact with the user's skin. The user can trigger the detection of electrocardiogram information by pressing the electrode E1. In this way, the problem of accidental triggering of electrocardiogram information detection due to accidental contact with the electrode E1 can be avoided.

[0122] In some implementations, other functions can also be achieved by pressing the electrode E1, such as powering on, powering off, or entering a menu. This application does not impose any specific limitations on this.

[0123] It is understandable that the above Figure 1A and Figure 1B This illustration only shows an exemplary arrangement of the ECG electrode of the detection device 10. In other embodiments, the ECG electrode may also be installed in other locations on the housing of the electronic device 1, and this application does not impose any specific limitations on this.

[0124] As mentioned earlier, at least part of the housing of electronic device 1 can be a metal casing. When the metal casing is conductive with the ECG electrode mounted on it, the leads formed by the ECG electrode will become abnormal, thus preventing the detection of electrocardiogram information. To avoid the metal casing interfering with the normal operation of the ECG electrode, it is necessary to ensure that the ECG electrode and the metal casing are insulated.

[0125] The following describes several insulation schemes, taking the metal casing as the middle frame 20 and the insulation between the middle frame 20 and the electrode E1 mounted on the middle frame 20 as examples.

[0126] Figure 2A A schematic diagram of the detection device 10 in some technical solutions is shown, in which the middle frame 20 is also shown for ease of observation. (Reference) Figure 2A The electrode E1 of the detection device 10 is a metal electrode.

[0127] To achieve insulation between electrode E1 and middle frame 20, detection device 10 may include plastic bracket 11, which is disposed between electrode E1 and middle frame 20. In this way, electrode E1 and middle frame 20 can be separated by plastic bracket 11, thereby preventing electrode E1 and middle frame 20 from conducting to each other.

[0128] In addition, to enable the pressing function of electrode E1, the detection device 10 may further include a connector 12 and an elastic element 13. The connector 12 is fixedly connected to the middle frame 20, and electrode E1 is disposed on the connector 12 and is movable relative to the connector 12 in the Z direction. Along the Z direction, the elastic element 13 is disposed between electrode E1 and connector 12. When electrode E1 is pressed along the Z direction, the elastic element 13 is compressed to provide a pressing feel; when electrode E1 is released, the elastic element 13 is released to allow electrode E1 to return to its original position.

[0129] It is worth noting that the aforementioned plastic bracket 11 has poor drop resistance reliability. When the electronic device 1 is dropped, the plastic bracket 11 is at risk of deformation. Furthermore, the plastic bracket 11 has low hardness, therefore it cannot effectively protect the electrode E1. It is only suitable for applications where the electrode E1 is a metal electrode, limiting the structural form of the electrode and its applicability. For example, in applications where the electrode E1 is a glass electrode, when the electronic device 1 falls to the ground, the edge area A0 of the electrode E1 is likely to come into direct contact with the ground, causing the electrode E1 to break due to lack of protection. Moreover, the plastic bracket 11 needs to be sufficiently thick to meet insulation requirements, resulting in a large footprint and low feasibility in small-sized layouts. For example, the dimension of the plastic bracket 11 along the X direction needs to be greater than or equal to 0.2 mm, with the X direction perpendicular to the Z direction.

[0130] Therefore, in some other technical solutions, a metal support is used to protect the glass electrode. Specifically, Figure 2B Schematic diagrams of the detection device 10 in other technical solutions are shown, in which the middle frame 20 is also shown for ease of observation. (Reference) Figure 2B The electrode E1 of the detection device 10 is a glass electrode.

[0131] The detection device 10 may include a titanium alloy bracket 14 mounted on the middle frame 20. The titanium alloy bracket 14 includes a supporting portion 141 and a limiting portion 142. The supporting portion 141 supports the bottom of the electrode E1 and is bonded to the electrode E1 by adhesive 15. The limiting portion 142 is provided on the supporting portion 141 and surrounds the electrode E1. Furthermore, the limiting portion 142 protrudes from the edge region A0 of the electrode E1 along the Z1 direction. Thus, when the electronic device 1 falls to the ground, the limiting portion 142 can contact the ground before the edge region A0 of the electrode E1, thereby protecting the electrode E1.

[0132] To achieve insulation between electrode E1 and the middle frame 20, an insulating coating (not shown) is provided on the surface of the titanium alloy support 14. This insulating coating is formed on the titanium alloy support 14 using physical vapor deposition (PVD). The titanium alloy support 14 is positioned between electrode E1 and the middle frame 20, and is insulated from both electrode E1 and the middle frame 20 by the insulating coating, thus achieving insulation between electrode E1 and the middle frame 20. Furthermore, the insulating coating is relatively thin; therefore, compared to the above... Figure 2A The plastic bracket 11 shown has an insulating coating that saves layout space.

[0133] Furthermore, to realize the detection function of the detection device 10, the detection device 10 may also include a circuit board 16 and electronic components 17, which are disposed within the cavity of the detection device 10. The circuit board 16 is used to receive the electrical signal from the electrode E1 to detect electrocardiogram (ECG) information based on the electrical signal. The electronic components 17 may be, for example, signal amplifiers, filters, analog-to-digital converters, or microprocessors; this application does not impose specific limitations on this. Additionally, the number of electronic components 17 may be one, two, three, four, or more; this application does not impose specific limitations on this.

[0134] It is worth noting that the insulating coating on the aforementioned titanium alloy bracket 14 has poor reliability and limited insulation effect, only meeting the insulation requirements of ordinary application scenarios (e.g., dry environments, clean places, and daily office wear), without considering the insulation requirements of some special application scenarios. For example, in water-ingress scenarios (e.g., hand washing, bathing, swimming, rain, and diving), dirty or prolonged use scenarios, the risk of continuity between electrode E1 and the middle frame 20 is relatively high, which will lead to a higher probability of abnormal conduction of electrode E1.

[0135] In summary, the current insulation solution cannot simultaneously guarantee drop resistance and insulation reliability in various application scenarios, resulting in poor performance of electrode E1.

[0136] In view of this, this application provides a detection device, which includes a metal component, an insulating component, and electrodes. The metal component protects the electrodes, and the insulating component provides insulation between the electrodes and the metal casing of the electronic device in which the detection device is located. By rationally designing the structure of the metal component and the insulating component, on the one hand, the electrodes can be protected, effectively improving their drop resistance, thus allowing for unrestricted electrode structure and a wide range of applications; on the other hand, insulation reliability can be effectively improved, preventing conductivity between the electrodes and the metal casing of the electronic device in various application scenarios, resulting in better electrode performance.

[0137] The technical solution of this application is described below with reference to the accompanying drawings.

[0138] Figure 3A and Figure 3B An exemplary structure of the detection device 10 in an embodiment of this application is shown, wherein, for ease of observation, the middle frame 20 is also shown. Figure 3A This is an assembly drawing of the detection device 10. Figure 3B This is an exploded view of the detection device 10. (Reference) Figure 3A and Figure 3BThe detection device 10 may include a first metal component 110, a first insulating component 120, and an electrode E1. The first metal component 110 and the first insulating component 120 may together form a support 100, which supports the electrode E1 to protect and insulate it.

[0139] Specifically, the first metal member 110 of the bracket 100 may include a groove structure 111, the opening of which faces the Z1 direction (as an example of the first direction). For example, in Figure 3A and Figure 3B In the embodiment shown, the Z1 direction is from bottom to top, or in other words, the Z1 direction is upward. Therefore, the opening of the groove structure 111 can be upward. When observing the groove structure 111 from the upward side, the interior of the groove structure 111 can be seen from the outside of the groove structure 111 through the opening of the groove structure 111.

[0140] The groove structure 111 may include a sidewall M1, a bottom wall M2, and an inner cavity M3. The space enclosed by the sidewall M1 and the bottom wall M2 is the inner cavity M3, which is the interior of the groove structure 111. The sidewall M1 may include an inner sidewall M11 and an outer sidewall M12. The inner sidewall M11 faces the inner cavity M3, and the outer sidewall M12 faces away from the inner cavity M3. Alternatively, the inner sidewall M11 can be understood as the inner surface of the groove structure 111, and the outer sidewall M12 as the outer surface of the groove structure 111. Similarly, the bottom wall M2 may also include an inner bottom wall (not shown) and an outer bottom wall (not shown). The inner bottom wall faces the inner cavity M3 and is the inner surface of the groove structure 111, while the outer bottom wall faces away from the inner cavity M3 and is the outer surface of the groove structure 111.

[0141] The first insulating element 120 of the bracket 100 includes a first portion 121 and / or a second portion (not shown). The first portion 121 may cover the inner sidewall M11 of the groove structure 111; the second portion may surround the groove structure 111 circumferentially and cover at least a portion of the outer sidewall M12 of the groove structure 111.

[0142] For example, in Figure 3A and Figure 3BIn the illustrated embodiment, the first insulating member 120 may include a first portion 121 but not a second portion; that is, the first insulating member 120 covers the inner sidewall M11 of the groove structure 111. In other embodiments, the first insulating member 120 may also include a second portion but not a first portion; that is, the first insulating member 120 surrounds the groove structure 111 circumferentially and covers at least a portion of the outer sidewall M12 of the groove structure 111. Alternatively, in other embodiments, the first insulating member 120 may also include a first portion 121 and a second portion 122; that is, the first insulating member 120 not only covers the inner sidewall M11 of the groove structure 111 but also surrounds the groove structure 111 circumferentially and covers at least a portion of the outer sidewall M12 of the groove structure 111.

[0143] Electrode E1 is located within the inner cavity M3 of the groove structure 111. It can be understood that when electrode E1 is located within the inner cavity M3 of the groove structure 111, the bottom surface F1 of electrode E1 can face the bottom wall M2 of the groove structure 111, the top surface F2 of electrode E1 faces away from the bottom wall M2 of the groove structure 111, and the side surface F3 of electrode E1 can face the side wall M1 of the groove structure 111. The side wall M1 of the groove structure 111 protrudes from electrode E1 along the Z1 direction; in other words, electrode E1 is recessed in the opposite direction to the side wall M1 of the groove structure 111 along the Z1 direction. A second insulating member 101 can be provided between electrode E1 and the bottom wall M2 of the groove structure 111, meaning that electrode E1 and the bottom wall M2 of the groove structure 111 are insulated from each other.

[0144] It is understood that in this application, an insulating component refers to a structural component made of insulating material with a specific shape and size; while an insulating medium is a substance, which can be solid, liquid, or gas. The shape and size of the insulating medium depend on the shape and size of the carrier that holds or contains the insulating medium. For example, the insulating medium can be an insulating coating or air. Compared to an insulating medium, an insulating component has a more reliable insulating effect.

[0145] The aforementioned detection device 10, on the one hand, by placing the electrode E1 in the inner cavity M3 of the groove structure 111 of the first metal part 110, and making the side wall M1 of the groove structure 111 protrude from the electrode E1 along the Z1 direction, can protect the electrode E1 and improve its drop resistance. The structural form of the electrode E1 is no longer limited, and its application range is wide. For example, in the application scenario where the electrode E1 is a glass electrode, when the detection device 10 falls to the ground, the side wall M1 of the groove structure 111 can contact the ground before the electrode E1. That is to say, the impact force of the drop will act on the side wall M1 of the groove structure 111, rather than on the electrode E1, thereby protecting the electrode E1 and preventing it from breaking.

[0146] On the other hand, by providing a first insulating member 120 on the first metal member 110, reliable insulation can be achieved between the electrode E1 and the metal casing (e.g., the middle frame 20) of the electronic device 1 where the detection device 10 is located, thus preventing conduction between the electrode E1 and the metal casing of the electronic device 1 where the detection device 10 is located in various application scenarios. Such application scenarios include water ingress scenarios (e.g., hand washing, bathing, swimming, rain, and diving), dirty scenarios, or scenarios involving prolonged use.

[0147] For example, in Figure 3A and Figure 3B In the illustrated embodiment, the first insulating member 120 may include a first portion 121. Thus, the first portion 121 provides insulation between the electrode E1 and the sidewall M1 of the groove structure 111 of the first metal member 110, and also between the electrode E1 and the bottom wall M2 of the groove structure 111. Therefore, the electrode E1 and the first metal member 110 are insulated from each other. Furthermore, after the electrode E1 is mounted in the electronic device 1 via the first metal member 110, the electrode E1 is insulated from the middle frame 20 of the electronic device 1.

[0148] For example, in some other embodiments, the first insulating member 120 may also include a second part. After the electrode E1 is installed in the electronic device 1 through the first metal member 110, the second part can achieve insulation between the first metal member 110 and the middle frame 20 of the electronic device 1, thereby ensuring that the electrode E1 is insulated from the middle frame 20.

[0149] For example, in some other embodiments, the first insulating member 120 may also include a first part 121 and a second part. After the electrode E1 is installed in the electronic device 1 through the first metal member 110, the electrode E1 and the first metal member 110 are insulated from each other, and the first metal member 110 is also insulated from the middle frame 20 of the electronic device 1. This can further improve the insulation reliability between the electrode E1 and the middle frame 20.

[0150] Depending on the different ways in which the first insulating element 120 is arranged on the groove structure 111, the bracket 100 can have different structural forms. The following will continue to describe in detail, with reference to the accompanying drawings, several exemplary structural forms of the bracket 100 provided in the embodiments of this application.

[0151] In some feasible embodiments, the first insulating element 120 may include a first portion 121.

[0152] Specifically, Figures 4A to 4C according to Figure 3A and Figure 3B An exemplary structure of the support 100 in an embodiment of this application is shown, wherein, Figure 4A This is a 3D view of bracket 100. Figure 4B For the support 100 along Figure 4A A sectional view obtained by cutting section AA in the middle. Figure 4C This is an exploded view of support 100 along the Z1 direction.

[0153] refer to Figures 4A to 4C The bottom wall M2 of the groove structure 111 may have a first through hole 112, which penetrates the bottom wall M2 of the groove structure 111 along the Z1 direction. The first through hole 112 can be understood as the inner cavity of the detection device (not shown), used to accommodate the structural components of the detection device. For example, these structural components may be... Figure 3A and Figure 3B The connector 12 in the illustrated embodiment can be used to connect structural components in the electronic device where the detection device 10 is located, thereby enabling the installation of the detection device 10. For example, these structural components can also be circuit boards and electronic devices disposed on the circuit boards, capable of receiving and processing the electrical signals from the electrode E1, thereby enabling the detection of electrocardiogram information. In some embodiments, after the detection device is installed in the electronic device, the first through hole 112 can communicate with the internal cavity of the electronic device.

[0154] It is understood that this application does not impose a specific limit on the number of first through holes 112, and the number of first through holes 112 can be one, two, three or four, etc.

[0155] To prevent structural components in the first through hole 112 from being damaged by moisture, a first groove 113 may be provided at the connection end between the inner bottom wall M21 and the inner side wall M11 of the groove structure 111. The first groove 113 surrounds the first through hole 112. It can be understood that the first groove 113 is provided on the outer edge of the inner bottom wall M21 of the groove structure 111, and one side wall of the first groove 113 may be connected to the inner side wall M11 of the groove structure 111 along the Z1 direction.

[0156] The first insulating member 120 also includes a third part 123, which is connected to the first part 121 along the Z1 direction. The third part 123 fills the first groove 113. That is, the first insulating member 120 is inserted into the first groove 113 along the inner sidewall M11 of the groove structure 111, wherein the first part 121 covers the inner sidewall M11 of the groove structure 111, and the third part 123 covers one sidewall of the first groove 113 and fills the first groove 113.

[0157] In this way, the first joint L1 between the groove structure 111 and the first insulating member 120 will not be directly connected to the first through hole 112, but will be separated by the groove structure 111. Therefore, liquid (e.g., water) outside the bracket 100 is unlikely to seep into the first through hole 112 or the inner cavity of the electronic device where the bracket 100 is located along the first joint L1, thereby preventing the structural components in the first through hole 112 and the inner cavity of the electronic device from being damaged by moisture, and effectively improving the sealing and waterproof performance of the bracket 100.

[0158] It should be noted that the first joint L1 refers to the boundary area between the groove structure 111 and the first insulating member 120, and is not a gap or opening in the physical sense. For ease of observation and description, the first joint L1 between the groove structure 111 and the first insulating member 120 is shown as a solid line in the figures of this article. However, this is only a schematic illustration. In fact, in some cases, the first joint L1 may not be visible to the naked eye.

[0159] In some embodiments of this application, the third portion 123 may protrude from the first portion 121 along the X1 direction (as an example of the second direction), or in other words, the first portion 121 may be recessed in the opposite direction of the third portion 123 along the X1 direction. The X1 direction is perpendicular to the Z1 direction and extends from the outside of the groove structure 111 to the inner cavity M3 of the groove structure 111. This facilitates the installation of a seal to seal the first joint L1, thereby further improving the sealing and waterproofing of the bracket 100.

[0160] For example, Figure 5 The detection device 10 in the embodiment of this application is shown. Figure 3A A magnified view of region A1 in the middle. (Reference) Figure 5 In some implementations, the second insulating member 101 can be used as a sealing member. The second insulating member 101 can cover the inner bottom wall M21 of the groove structure 111 and a portion of the first surface 1231 of the third part 123 facing the Z1 direction, thereby achieving a seal on the first joint L1. This eliminates the need for additional sealing members to seal the first joint L1, reducing the number of components and simplifying the overall structure. Figure 5 In the embodiment shown, the Z1 direction is the direction from bottom to top, or in other words, the Z1 direction is the upward direction. Therefore, the first surface 1231 can be the upward-facing surface of the third part 123. That is, the first surface 1231 is the upper surface of the third part 123. When observing the third part 123 from the upward-facing side, the first surface 1231 can be seen.

[0161] In some implementations, the inner bottom wall M21 and the first surface 1231 can be flush, thus reducing the difficulty of setting up and sealing the seal. For example, in Figure 5 In the example shown, the second insulating element 101 can cover a portion of the inner bottom wall M21 and the first surface 1231 relatively smoothly, thereby achieving a better sealing effect.

[0162] In some embodiments of this application, the second insulating member 101 can be an insulating adhesive. In this way, the second insulating member 101 can also achieve a fixed connection between the electrode E1 and the bottom wall M2 of the groove structure 111, preventing the electrode E1 from falling out of the groove structure 111.

[0163] Continue to refer to Figure 3A In some embodiments of this application, the detection device 10 may further include a sealing ring 102, which is sleeved on the outside of the bracket 100 to seal the gap between the bracket 100 and the middle frame 20. Liquids (e.g., water) outside the detection device 10 are less likely to seep into the first through hole 112 or the inner cavity of the electronic device 1 where the detection device 10 is located through the gap between the bracket 100 and the middle frame 20, thereby preventing moisture damage to structural components in the first through hole 112 and the inner cavity of the electronic device 1, effectively improving the sealing and waterproofing of the detection device 10.

[0164] In some other feasible embodiments, the first insulating element 120 may include a second part 122.

[0165] Specifically, Figure 6A and Figure 6B An exemplary structure two of the detection device 10 in an embodiment of this application is shown, wherein, for ease of observation, the middle frame 20 is also shown. Figure 6A This is an assembly drawing of the detection device 10. Figure 6B This is an exploded view of the detection device 10. Compared to Figure 3A and Figure 3B The detection device 10 shown, Figure 6A and Figure 6B The difference in the detection device 10 shown is that the first insulating member 120 is arranged differently on the groove structure 111.

[0166] refer to Figure 6A and Figure 6B The first insulating member 120 may include a second portion 122, which may surround the groove structure 111 circumferentially and cover at least a portion of the outer wall M12 of the groove structure 111. That is, the second portion 122 is an annular structure. Along the Z1 direction, the size of the annular second portion 122 may be smaller than the size of the outer wall M12 of the groove structure 111 to cover a portion of the outer wall M12; or, along the Z1 direction, the size of the annular second portion 122 may be equal to the size of the outer wall M12 of the groove structure 111 to cover the entire area of ​​the outer wall M12.

[0167] Figures 7A to 7C according to Figure 6A and Figure 6B An exemplary structure of the support 100 in an embodiment of this application is shown, wherein, Figure 7A This is a 3D view of bracket 100. Figure 7B For the support 100 along Figure 6A A sectional view obtained by cutting the middle BB section. Figure 7C This is an exploded view of support 100 along the Z1 direction.

[0168] refer to Figures 7A to 7C The bottom wall M2 of the groove structure 111 may have a first through hole 112, and the first through hole 112 is related to the above. Figures 4A to 4C The through holes in the illustrated embodiments are essentially the same, therefore the above description can be used as a reference. Figures 4A to 4C The first through hole 112 in the illustrated embodiment will not be described in detail here.

[0169] To prevent structural components in the first through hole 112 from being damaged by moisture, the outer wall M12 of the groove structure 111 may include a first annular region S1 and a second annular region S2. The first annular region S1 and the second annular region S2 are connected along the Z1 direction and extend circumferentially along the groove structure 111, respectively. For example, the circumferential direction of the groove structure 111 may be... Figure 7A The N direction in the illustrated embodiment.

[0170] The first annular region S1 is located at the end of the outer wall M12 facing away from Z1. For example, in Figures 7A to 7C In the embodiment shown, the Z1 direction is from bottom to top, or in other words, the Z1 direction is upward. Therefore, the end of the outer wall M12 facing away from the Z1 direction can be the end of the outer wall M12 facing downward, that is, the lower end of the outer wall M12. When observing the outer wall M12 from the side facing downward, the lower end of the outer wall M12 can be seen.

[0171] The second portion 122 of the first insulating member 120 covers the second annular region S2. Furthermore, the first end S21 of the second annular region S2 is recessed relative to the first annular region S1 along the X1 direction; or, in other words, the first annular region S1 protrudes beyond the first end S21 of the second annular region S2 in the opposite direction of the X1 direction. The first end S21 is the end of the second annular region S2 closest to the first annular region S1 along the Z1 direction; or, in other words, the first end S21 is the connecting end where the second annular region S2 and the first annular region S1 are connected.

[0172] In this way, the first joint L1 between the groove structure 111 and the first insulating member 120 extends to the outer wall M12 of the groove structure 111. Therefore, liquids (e.g., water) outside the bracket 100 are unlikely to seep into the first through hole 112 or the inner cavity of the electronic device where the bracket 100 is located along the first joint L1. This prevents the structural components in the first through hole 112 and the inner cavity of the electronic device from being damaged by moisture, effectively improving the sealing and waterproof performance of the bracket 100. At the same time, it also facilitates the installation of a sealing member to seal the first joint L1, effectively reducing the difficulty of sealing the first joint L1.

[0173] For example, Figure 8 The detection device 10 in the embodiment of this application is shown. Figure 6A A magnified view of region A2 in the middle. (Reference) Figure 8 In some implementations, the sealing ring 102 can be used as a sealing element. The sealing ring 102 can be sleeved on the outside of the second part 122 and the second annular region S2 to seal the first joint L1. In this way, there is no need to set other sealing elements to seal the first joint L1, reducing the number of parts and making the overall structure simpler.

[0174] Continue to refer to Figures 7A to 7C In some embodiments of this application, the outer wall M12 of the groove structure 111 may further include a third annular region S3, which extends along the N direction, and the first annular region S1, the second annular region S2 and the third annular region S3 are arranged sequentially along the Z1 direction.

[0175] Specifically, the second end S22 of the second annular region S2 is concave in the X1 direction compared to the third annular region S3, or in other words, the third annular region S3 protrudes beyond the second end S22 of the second annular region S2 in the opposite direction of the X1 direction. The second end S22 is the end of the second annular region S2 closest to the third annular region S3 in the Z1 direction; or, in other words, the second end S22 is the connecting end between the second annular region S2 and the third annular region S3.

[0176] After the bracket 100 is installed in the electronic device, the third annular region S3 can be located on the outer surface of the electronic device. The material of the third annular region S3 is metal, so that when the electronic device is dropped, the third annular region S3 can withstand greater drop impact, thereby further improving drop resistance.

[0177] In other feasible embodiments, the first insulating element 120 may also include a first portion 121 and a second portion 122. The specific arrangement of the first portion 121 is as described above. Figures 3A to 5 The first part 121 in the illustrated embodiment is substantially the same, therefore it can be referred to the above. Figures 3A to 5The relevant descriptions in the illustrated embodiments; the specific settings of the second part 122 are the same as described above. Figures 6A to 8 The second part 122 in the illustrated embodiment is substantially the same, therefore reference can be made to the above. Figures 6A to 8 The relevant descriptions in the illustrated embodiments will not be repeated here.

[0178] After introducing several ways of setting the first insulating element 120 on the groove structure 111, we will continue to introduce several forms of the first insulating element 120.

[0179] In some feasible embodiments, the first insulating element 120 may include a first plastic element and / or a first sealant, as exemplified below.

[0180] In some embodiments of this application, the first insulating member 120 may include a first plastic member, that is, at least a portion of the material of the first insulating member 120 is plastic.

[0181] In some of these implementations, the first plastic part can constitute the above-mentioned... Figures 3A to 5 The first part 121, the third part 123, and the above-mentioned embodiment are shown in the figure. Figures 6A to 8 In the illustrated embodiment, any one or more portions of the second part 122, that is, any one or more of the first part 121, the second part 122, and the third part 123, can be made of plastic.

[0182] In some implementations, the first plastic part and the first metal part 110 can be a single integrated structure, eliminating the need for subsequent assembly of the first metal part 110 and the first plastic part of the first insulating part 120. That is, the structure formed by the first metal part 110 and the first plastic part of the first insulating part 120 is a single, indivisible whole, rather than assembled from multiple physically independent components. Alternatively, the first metal part 110 and the first plastic part of the first insulating part 120 can be integrally molded; for example, they can be integrally molded using insert injection molding.

[0183] By setting the first metal part 110 and the first plastic part of the first insulating part 120 as an integral structure, the number of parts of the detection device 10 can be effectively reduced, the assembly efficiency of the detection device 10 can be improved, and the bonding between the first metal part 110 and the first plastic part of the first insulating part 120 can be made tighter, thereby further improving the sealing and waterproof performance.

[0184] In some implementations, the dimension of the first plastic part along the X1 direction can be greater than or equal to 0.2 mm, for example, 0.2 mm, 0.3 mm, 0.4 mm or 0.5 mm, so that the first plastic part can have a better insulation effect.

[0185] In other embodiments of this application, the first insulating member 120 may also include a first sealant, which is thinner, therefore, compared to the above... Figure 2A The plastic bracket 11 shown can effectively save layout space to meet the insulation requirements of small layout spaces.

[0186] Specifically, Figure 9A This illustrates an exemplary arrangement of the first sealant 124 of the first insulating member 120 in an embodiment of this application. Figure 9B The detection device 10 in the embodiment of this application is shown. Figure 9A A magnified view of a portion of region A3 in the middle. Figure 9C The detection device 10 in the embodiment of this application is shown. Figure 9A The second enlarged view of region A3 in the middle, where, Figure 9C The first sealant 124 is not shown.

[0187] refer to Figures 9A to 9C The first sealant 124 can be filled between the inner wall M11 of the groove structure 111 and the electrode E1. The space between the inner wall M11 of the groove structure 111 and the electrode E1 may include a first gap G1 and a second gap G2, which can be arranged along the Z1 direction. Furthermore, the width of the first gap G1 is greater than the width of the second gap G2, wherein the width of the first gap G1 can be the dimension of the first gap G1 along the X1 direction, and the width of the second gap G2 can be the dimension of the second gap G2 along the X1 direction.

[0188] In this way, the first sealant 124 can be effectively guided to fully fill the space between the inner wall M11 of the groove structure 111 and the electrode E1, thereby further enhancing the insulation effect between the groove structure 111 and the electrode E1.

[0189] It can be understood that the first gap G1 and the second gap G2 are two gaps at any position in the gap section G0 between the inner sidewall M11 of the groove structure 111 and the electrode E1. The gap section G12 from the first gap G1 to the second gap G2 can be a part of the gap section G0 or the entire gap section G0.

[0190] For example, in Figure 9CIn the illustrated embodiment, gap segment G12 can be the lower half of gap segment G0. The first gap G1 can be located at the end of gap segment G0 facing away from the Z1 direction. For example, the Z1 direction is from bottom to top, or in other words, the Z1 direction is upward. Therefore, the end of gap segment G0 facing away from the Z1 direction can be the downward-facing end of gap segment G0, that is, the lower end of gap segment G0. The second gap G2 can be located in the middle part of gap segment G0.

[0191] In some implementations, the width of the gap segment G12 can gradually decrease along the Z1 direction, thus giving it an overall trumpet-like shape. The reduction in the width of the gap segment G12 can be a continuous and smooth decrease along Z1, a step-like decrease, or a combination of continuous and smooth decreases along Z1 and step-like decreases along Z1. This application does not impose specific limitations on this.

[0192] In some embodiments of this application, during the filling of the first sealant 124, an excess of the first sealant 124 can be applied to the groove structure 111 firstly, and then the electrode E1 can be placed on the first sealant 124 and pressed to squeeze the first sealant 124. The excess sealant 124 that overflows can then be wiped away. This ensures that the first sealant 124 is more fully filled between the inner wall M11 of the groove structure 111 and the electrode E1, thereby further enhancing the insulation effect.

[0193] In some embodiments of this application, the inner bottom wall M21 of the groove structure 111 and the electrode E1 may also be filled with a first sealant 124, thereby further enhancing the insulation effect between the groove structure 111 and the electrode E1. Based on this, an insulating protrusion 114 (or "spacer") may be provided between the inner bottom wall M21 of the groove structure 111 and the electrode E1. The insulating protrusion 114 can support the electrode E1 to ensure that there is an appropriate gap between the electrode E1 and the inner bottom wall M21 of the support 100, and to prevent the electrode E1 from excessively squeezing the first sealant 124 between the inner bottom wall M21 of the groove structure 111 and the electrode E1 during installation.

[0194] In some implementations, the insulating protrusion 114 and the groove structure 111 are an integral structure, which effectively reduces the number of parts of the detection device 10 and improves the assembly efficiency of the detection device 10.

[0195] It is understood that this application does not impose specific limitations on the orientation and number of the insulating protrusions 114, as long as they can achieve the aforementioned supporting effect. For example, in Figure 9B and Figure 9CIn the illustrated embodiment, only one insulating protrusion 114 is shown, which is located at one end of the inner bottom wall M21 near the inner side wall M11. In other embodiments, the number of insulating protrusions 114 may vary, including other parts of the inner bottom wall M21, such as one, two, three, or four. Figure 10 The arrangement of the insulating protrusion 114 is shown in some other embodiments of this application, see reference. Figure 10 There are three insulating protrusions 114, and all three insulating protrusions 114 are located at one end of the inner bottom wall M21 near the first through hole 112.

[0196] In the above Figures 9A to 9C In the illustrated embodiment, the first sealant 124 covers the inner wall M11 of the groove structure 111, and the first sealant 124 can constitute the above-described... Figures 3A to 5 The first part 121 in the illustrated embodiment is shown, but this application is not limited thereto.

[0197] In other embodiments of this application, the first insulating member 120 may also include a first plastic member and a first sealant 124, the first plastic member being configured as described above. Figures 3A to 5 In the illustrated embodiment, the first portion 121 and the first sealant 124 can be filled between the first portion 121 and the electrode E1. The structural form of the gap section between the first portion 121 and the electrode E1 is similar to that described above. Figures 9A to 9C The gap segment G0 in the illustrated embodiment is essentially the same, therefore it can be referred to the above. Figures 9A to 9C The relevant descriptions in the illustrated embodiments will not be repeated here.

[0198] In addition to the above, Figures 3A to 8 Compared to the detection device 10 in the illustrated embodiment, Figure 9A The detection device 10 in the illustrated embodiment may also include more electronic components.

[0199] Specifically, refer to Figure 9ATo realize the detection function of the detection device 10, in some embodiments of this application, the detection device 10 may further include a circuit board 16 and electronic components 17, which are disposed in the first through hole 112, i.e., the inner cavity of the detection device 10. The circuit board 16 is used to receive the electrical signal from the electrode E1 to detect electrocardiogram information based on the electrical signal. Exemplarily, a conductive silicone rubber 18 may be provided between the circuit board 16 and the electrode E1, and the conductive silicone rubber 18 abuts against the pads (not shown) on the electrode E1 and the circuit board 16 to enable signal transmission between the electrode E1 and the circuit board 16. The electronic components 17 may be, for example, signal amplifiers, filters, analog-to-digital converters, or microprocessors, etc., and this application does not impose specific limitations on this. Furthermore, the number of electronic components 17 may be one, two, three, four, or more, etc., and this application does not impose specific limitations on this.

[0200] As previously mentioned, the first metal component 110 and the first insulating component 120 can together constitute the support 100. In some feasible embodiments, air and / or insulating ink can be provided between the support 100 and the side F3 of the electrode E1 to further improve the insulation reliability between the support 100 and the electrode E1.

[0201] The following are examples.

[0202] Figure 11 This diagram illustrates an embodiment of the present application where air is provided between the support 100 and the side F3 of the electrode E1. It should be noted that, for ease of observation, Figure 11 Only the bracket 100 is shown, without distinguishing between the first metal part and the first insulating part of the bracket 100. The bracket 100 may specifically be as described above. Figures 3A to 9C Any of the brackets 100 shown in the embodiments.

[0203] refer to Figure 11 In some embodiments of this application, air may be provided between the support 100 and the side surface F3 of the electrode E1. That is, there may be a gap G0′ between the support 100 and the side surface F3 of the electrode E1, or in other words, the support 100 and the side surface F3 of the electrode E1 are separated by air, and the side surface F3 of the electrode E1 does not contact the support 100. Air is an insulating medium, which spatially isolates the support 100 and the side surface F3 of the electrode E1, thereby further improving the insulation reliability between the support 100 and the electrode E1. The gap G0′ can also be called a microslit, that is, insulation is achieved through a microslit structure.

[0204] Figure 12 according to Figure 11 This diagram illustrates the installation of electrode E1 and bracket 100 in an embodiment of this application. Figure 12 for Figure 11 A bird's-eye view. (Reference) Figure 12 During the installation of electrode E1 onto bracket 100, electrode E1 and bracket 100 can be placed on worktable 2, and insulating film 3 can be placed on bracket 100. A limiting member (not shown) provides a limit to insulating film 3 to prevent unnecessary displacement. Then, electrode E1 is installed in bracket 100. During this process, electrode E1 can be pressed down along with insulating film 3. After electrode E1 is installed in bracket 100, insulating film 3 is squeezed between side F3 of electrode E1 and bracket 100. Electrode E1 and bracket 100 can be fixed together with adhesive. After the adhesive between electrode E1 and bracket 100 has cured, insulating film 3 is removed. This ensures that there is a gap G0′ between bracket 100 and side F3 of electrode E1 after assembly. It can be understood that the thickness of insulating film 3 determines the size of gap G0′; the thicker the insulating film 3, the larger the gap G0′, and vice versa.

[0205] In some implementations, the thickness of the insulating film 3 may be less than or equal to 0.1 mm, for example, 0.01 mm, 0.02 mm, 0.03 mm, 0.04 mm or 0.05 mm, etc., and this application does not impose specific limitations on it.

[0206] In some implementations, the insulating film 3 may be, for example, an insulating pad or a disposable release film, and this application does not impose any specific limitations on it.

[0207] In some implementations, to ensure the stability of the adhesion between electrode E1 and support 100, pressure can be applied to electrode E1 and support 100 using a pressure-holding fixture until the adhesive between electrode E1 and support 100 cures. When the insulating film 3 is a disposable release film, the disposable release film can be transferred along with the pressure-holding fixture, and the disposable release film can be peeled off after the adhesive between electrode E1 and support 100 has cured.

[0208] Figure 13A and Figure 13B An exemplary structure of electrode E1 in an embodiment of this application is shown, wherein, Figure 13A This is a 3D view of electrode E1. Figure 13B For electrode E1 along Figure 13A A sectional view obtained by cutting along the CC section. (Reference) Figure 13A and Figure 13B In some embodiments of this application, insulating ink 103 may be provided on the side F3 of electrode E1. The insulating ink 103 covers the side F3 of electrode E1, thus separating the side F3 of electrode E1 from the support (not shown), thereby further improving the insulation reliability between electrode E1 and the support. The insulating ink 103 is relatively thin; therefore, compared to the above... Figure 2AThe plastic bracket 11 shown can effectively save layout space to meet the insulation requirements of small layout spaces.

[0209] In some implementations, the bottom surface F1 of electrode E1 may include a first conductive layer F11, the top surface F2 of electrode E1 may include a second conductive layer F21, and the side surface F3 of electrode E1 may include a third conductive layer F31. Insulating ink 103 may cover the third conductive layer F31. The first conductive layer F11 is used for electrical connection with a circuit board (not shown), and the second conductive layer F21 is used for contact with the user. The first conductive layer F11 and the second conductive layer F21 can be connected through the third conductive layer F31. Thus, when the user touches the second conductive layer F21, the generated electrical signal can be transmitted sequentially through the second conductive layer F21, the third conductive layer F31, and the first conductive layer F11 to the circuit board, thereby realizing the detection of electrocardiogram information.

[0210] Electrode E1 may also include a glass substrate L (or “lens”), and the first conductive layer F11, the second conductive layer F21 and the third conductive layer F31 may cover the glass substrate L, which serves as a carrier for the first conductive layer F11, the second conductive layer F21 and the third conductive layer F31.

[0211] For example, a first conductive layer F11, a second conductive layer F21 and a third conductive layer F31 can be formed on the surface of a glass substrate L by coating, and then an insulating ink 103 is added to cover the third conductive layer F31.

[0212] For example, the surface of electrode E1 may also be provided with a diamond-like carbon (DLC) film to provide protection such as wear resistance, corrosion resistance, and oxidation prevention. Therefore, electrode E1 can also be referred to as a lens DLC electrode.

[0213] In some feasible solutions, the insulation reliability between electrode E1 and support 100 can be further improved by rationally designing the layout of each conductive layer in electrode E1.

[0214] Specifically, Figure 14A and Figure 14B An exemplary second structure of electrode E1 in an embodiment of this application is shown, wherein, Figure 14A This is a 3D view of electrode E1. Figure 14B For electrode E1 along Figure 14A A sectional view obtained by cutting the middle DD section. (Reference) Figure 14A and Figure 14BIn some embodiments of this application, electrode E1 may include a first conductive layer F11, a second conductive layer F21, and a third conductive layer F31. The first conductive layer F11 and the second conductive layer F21 can be connected through the third conductive layer F31. It is understood that the specific orientation of the first conductive layer F11, the second conductive layer F21, and the third conductive layer F31 can be referred to the above description. Figure 13A and Figure 13B The relevant descriptions in the illustrated embodiments will not be repeated here.

[0215] The ratio between the area of ​​the third conductive layer F31 and the side surface F3 of electrode E1 can be from 0.001 to 0.1, for example, 0.001, 0.002, 0.003, 0.004, 0.005, 0.006, or 0.007. In other words, only a portion of the side surface F3 of electrode E1 is conductive. This effectively reduces the risk of conductivity between the side surface F3 of electrode E1 and the support (not shown), resulting in better insulation reliability between electrode E1 and the support.

[0216] In some of these implementations, the third conductive layer F31 can be formed by a masking process, which is a localized coating process in which a mask is used to cover areas where no film is needed, allowing the film to be selectively formed only in specific areas.

[0217] Figure 15 An exemplary structure three of electrode E1 in an embodiment of this application is shown. (Reference) Figure 15 In some embodiments of this application, the ratio between the area of ​​the first conductive layer F11 and the bottom surface F1 of the electrode E1 can be from 0.01 to 0.5, for example, 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, or 0.07. That is, only a portion of the bottom surface F1 of the electrode E1 is conductive. This effectively reduces the risk of conductivity between the bottom surface F1 of the electrode E1 and the support (not shown), resulting in better insulation reliability between the electrode E1 and the support.

[0218] Continue to refer to Figure 15 The ratio between the area of ​​the third conductive layer F31 and the side surface F3 of electrode E1 can be from 0.001 to 0.1, for example, 0.001, 0.002, 0.003, 0.004, 0.005, 0.006, or 0.007. That is, only a portion of the side surface F3 of electrode E1 is conductive. This effectively reduces the risk of conductivity between the side surface F3 of electrode E1 and the support (not shown), resulting in better insulation reliability between electrode E1 and the support.

[0219] In some of these implementations, the first conductive layer F11 and the third conductive layer F31 can be formed by a masking process.

[0220] Figures 16A to 16C An exemplary structure four of electrode E1 in an embodiment of this application is shown, wherein, Figure 16A This is a 3D view of electrode E1. Figure 16B This is a stereoscopic view of electrode E1 from another perspective. Figure 16C For electrode E1 along Figure 13A A sectional view obtained by cutting the EE section.

[0221] refer to Figures 16A to 16C In some embodiments of this application, electrode E1 may include a first conductive layer F11 and a second conductive layer F21. It can be understood that the specific orientation of the first conductive layer F11 and the second conductive layer F21 can be referred to the above description. Figure 13A and Figure 13B The relevant descriptions in the illustrated embodiments will not be repeated here.

[0222] The electrode E1 may have a conductive via H1, which penetrates the electrode E1 along the Z1 direction. The first conductive layer F11 and the second conductive layer F21 can be connected through the conductive via H1. Thus, when the user touches the second conductive layer F21, the generated electrical signal can be transmitted sequentially through the second conductive layer F21, the conductive via H1, and the first conductive layer F11 to the circuit board, thereby realizing the detection of electrocardiogram information. This eliminates the need to transmit signals through the side F3 of the electrode E1. Therefore, the conductive layer of the side F3 of the electrode E1 can be insulated from the first conductive layer F11 and the second conductive layer F21, or the side F3 of the electrode E1 can be made insulated to ensure that the contact between the side F3 of the electrode E1 and the support (not shown) does not affect the signal transmission effect between the first conductive layer F11 and the second conductive layer F21.

[0223] Continue to refer to Figures 16A to 16C In some implementations, the side surface F3 of electrode E1 may include a fourth conductive layer F32, and the first conductive layer F11 and the second conductive layer F21 are respectively insulated from the fourth conductive layer F32.

[0224] In this way, even if the fourth conductive layer F32 is connected to the support (not shown), it will not affect the signal transmission effect between the first conductive layer F11 and the second conductive layer F21, thereby ensuring that the electrode E1 can work normally.

[0225] For example, a first conductive layer F11, a second conductive layer F21, and a fourth conductive layer F32 can be formed on the surface of a glass substrate L by coating. Then, the connection area between the first conductive layer F11 and the fourth conductive layer F32 and the connection area between the second conductive layer F21 and the fourth conductive layer F32 can be broken by laser engraving, so that the first conductive layer F11 and the second conductive layer F21 are insulated from the fourth conductive layer F32.

[0226] Alternatively, in some other alternative implementations, the side surface F3 of electrode E1 may not include the fourth conductive layer F32, that is, the side surface F3 of electrode E1 is insulated.

[0227] It is understandable that the above Figures 3A to 16C The insulation schemes in the illustrated embodiments can be combined arbitrarily or implemented individually. This application does not impose specific limitations on this, as long as the insulation requirements are met. For example, in some embodiments, the above-mentioned... Figures 3A to 5 The insulation scheme shown is the same as the one described above. Figures 6A to 8 The insulation schemes shown are combined to achieve the insulation effect. Alternatively, in some other embodiments, the above-described insulation methods can also be combined... Figures 6A to 8 The insulation scheme shown is the same as the one described above. Figures 9A to 16C Any one or more insulation schemes shown can be combined to achieve the insulation effect. Furthermore, in some other embodiments, the above-described methods can also be used. Figures 3A to 16C Any of the insulation schemes shown can be used to achieve the insulation effect.

[0228] This application also provides a detection device, which may include a second metal component and a third insulating component. The third insulating component has a frame-shaped structure. The second metal component and the third insulating component are stacked along the Z1 direction and together form a receiving cavity. It can be understood that the second metal component is the bottom wall of the receiving cavity, and the third insulating component is the side wall of the receiving cavity. An electrode can be disposed in this receiving cavity. The third insulating component protrudes from the electrode along the Z1 direction, and a fourth insulating component is provided between the electrode and the second metal component. In this way, the issues of drop resistance and insulation reliability under various application scenarios can be addressed simultaneously, effectively improving the working performance of the electrode.

[0229] Specifically, Figure 17A and Figure 17B An exemplary structure three of the detection device 10 in an embodiment of this application is shown, wherein, for ease of observation, the middle frame 20 is also shown. Figure 17A This is an assembly drawing of the detection device 10. Figure 17B This is an exploded view of a portion of the structure in the detection device 10. (Reference) Figure 17A and Figure 17B The detection device 10 may include a second metal component 210, a third insulating component 220, and an electrode E1. The second metal component 210 and the third insulating component 220 may together form a support 200, which supports the electrode E1 to protect and insulate it.

[0230] Specifically, the second metal member 210 of the bracket 200 serves as a support for the detection device 10, supporting components of the detection device 10, such as the third insulating member 220, the electrode E1, and the sealing ring 102. The third insulating member 220 of the bracket 200 has a frame-shaped structure. In some embodiments of this application, the frame-shaped structure can be a circular frame-shaped structure, a rectangular frame-shaped structure, a pentagonal frame-shaped structure, a polygonal frame-shaped structure with more sides, or other irregularly shaped frame-shaped structures; this application does not impose specific limitations on this. The second metal member 210 and the third insulating member 220 are stacked along the Z1 direction (as an example of the first direction) and together form the receiving cavity 230.

[0231] Electrode E1 is located in the receiving cavity 230. It can be understood that when electrode E1 is in the receiving cavity 230, its bottom surface F1 can face the bottom wall of the receiving cavity 230, and its top surface F2 faces away from the bottom wall of the receiving cavity 230. The bottom wall of the receiving cavity 230 can be, for example, the second metal member 210. The side surface F3 of electrode E1 can face the side wall of the receiving cavity 230, which can be, for example, the third insulating member 220. The third insulating member 220 protrudes from electrode E1 along the Z1 direction, or in other words, electrode E1 is recessed in the opposite direction of the third insulating member 220 along the Z1 direction. A fourth insulating member 201 is provided between electrode E1 and the second metal member 210, meaning that electrode E1 and the second metal member 210 are insulated from each other.

[0232] The aforementioned detection device 10, on the one hand, by placing the electrode E1 within the receiving cavity 230 formed by the second metal part 210 and the third insulating part 220, and by making the third insulating part 220 protrude from the electrode E1 along the Z1 direction, can protect the electrode E1 and improve its drop resistance. The structural form of the electrode E1 is no longer limited, and its application range is wide. For example, in applications where the electrode E1 is a glass electrode, when the detection device 10 falls to the ground, the third insulating part 220 can contact the ground before the electrode E1. That is, the impact force will act on the third insulating part 220 instead of the electrode E1, thus protecting the electrode E1 and preventing it from breaking. Furthermore, due to the support of the second metal part 210, the third insulating part 220 will not undergo significant deformation, thus effectively protecting the electrode E1.

[0233] On the other hand, by providing a third insulating member 220 and a fourth insulating member 201 on the second metal member 210, reliable insulation between the electrode E1 and the second metal member 210 can be achieved, thereby achieving reliable insulation between the electrode E1 and the metal casing (e.g., the middle frame 20) of the electronic device 1 where the detection device 10 is located, preventing conduction between the electrode E1 and the metal casing of the electronic device 1 where the detection device 10 is located in various application scenarios. These application scenarios include, for example, water ingress scenarios (e.g., handwashing, bathing, swimming, rain, and diving), dirty scenarios, or scenarios involving prolonged use.

[0234] Continue to refer to Figure 17A and Figure 17B In some embodiments of this application, a second through hole 211 may be provided on the second metal part 210, and the second through hole 211 penetrates the second metal part 210 along the Z1 direction. The second through hole 211 can be understood as the inner cavity of the detection device 10, used to accommodate the structural components of the detection device 10, such as the connector 12, the circuit board 16, and the electronic device 17. The function of the connector 12 can be referred to the above description. Figures 4A to 4C The functions of the circuit board 16 and electronic device 17 in the illustrated embodiments can be referred to the above descriptions. Figures 9A to 9C The relevant descriptions in the illustrated embodiments will not be repeated here. In some embodiments, after the detection device 10 is installed in the electronic device 1, the second through hole 211 can communicate with the inner cavity of the electronic device 1.

[0235] To prevent the structural components in the second through hole 211 from being damaged by moisture, the structural form of the second metal part 210 needs to be designed reasonably.

[0236] Specifically, Figure 18 An exemplary structure of the second metal component 210 in an embodiment of this application is shown. (See reference...) Figure 18 and combined Figure 17A and Figure 17B In some embodiments of this application, a second groove 213 is provided at the connection end between the second surface 212 of the second metal member 210 facing the Z1 direction and the third insulating member 220, and the second groove 213 surrounds the second through hole 211. It can be understood that the second groove 213 is provided on the outer edge of the second metal member 210. Wherein, in Figure 18 In the embodiment shown, the Z1 direction is from bottom to top, or in other words, the Z1 direction is upward. Therefore, the second surface 212 can be the upward-facing surface of the second metal part 210. That is, the second surface 212 is the upper surface of the second metal part 210. When observing the second metal part 210 from the upward-facing side, the second surface 212 can be seen.

[0237] The third insulating element 220 includes a fourth part 221 and a fifth part 222, which are connected along the Z1 direction. The fourth part 221 is filled in the second groove 213, and the fifth part 222 is located outside the second groove 213.

[0238] In this way, the second joint L2 between the second metal part 210 and the third insulating part 220 will not be directly connected to the second through hole 211, but will be separated by the second metal part 210. Therefore, liquid (e.g., water) outside the bracket 200 is unlikely to seep into the second through hole 211 or the inner cavity of the electronic device 1 through the second joint L2, thereby preventing the structural components in the first through hole 112 and the inner cavity of the electronic device 1 from being damaged by moisture, and effectively improving the sealing and waterproof performance of the bracket 200.

[0239] It should be noted that the second joint L2 refers to the boundary area between the second metal part 210 and the third insulating part 220, and is not a gap or opening in the physical sense. For ease of observation and description, the second joint L2 between the second metal part 210 and the third insulating part 220 is shown as a solid line in the figures in this article. However, this is only for illustrative purposes. In fact, in some cases, the second joint L2 may not be visible to the naked eye.

[0240] It should be noted that the above Figure 18 In the illustrated embodiment, the second groove 213 is an L-shaped groove, for example, in Figure 18 In the cross-section shown, the bottom wall and side wall of the second groove 213 form a structure that is similar to an L-shape, but this application is not limited to this. Figure 19 Exemplary structures of the second groove 213 in other embodiments of this application are shown. For example... Figure 19 As shown, the second groove 213 can also be a U-shaped groove, for example in... Figure 19 In the cross-section shown, the structure formed by the bottom wall and side wall of the second groove 213 is similar to a U-shape.

[0241] Figure 20 Exemplary structures for parts 221 and 222 in embodiments of this application are shown. (See reference...) Figure 20 In some embodiments of this application, the fourth portion 221 may protrude from the fifth portion 222 along the X1 direction (as an example of the second direction), or in other words, the fifth portion 222 may be recessed in the opposite direction of the fourth portion 221 along the X1 direction. This facilitates the installation of a seal to seal the second joint L2, thereby further improving the sealing and waterproofing of the detection device 10.

[0242] In some implementations, the fourth insulating member 201 can be used as a sealing member. The fourth insulating member 201 can cover the second surface 212 of the second metal member 210 and a portion of the third surface 2211 of the fourth part 221 facing the Z1 direction, thereby sealing the second joint L2. This eliminates the need for additional sealing members to seal the second joint L2, reducing the number of components and simplifying the overall structure. Figure 20 In the embodiment shown, the Z1 direction is the direction from bottom to top, or in other words, the Z1 direction is the upward direction. Therefore, the third surface 2211 can be the upward-facing surface of the fourth part 221. That is, the third surface 2211 is the upper surface of the fourth part 221. When observing the fourth part 221 from the upward-facing side, the third surface 2211 can be seen.

[0243] In some implementations, the second surface 212 of the second metal part 210 and the third surface 2211 of the fourth part 221 are flush, which reduces the difficulty of setting up and sealing the seal. For example, in Figure 20 In the embodiment shown, the fourth insulating element 201 can cover a portion of the second surface 212 and the third surface 2211 relatively smoothly, thereby achieving a better sealing effect.

[0244] In some embodiments of this application, the fourth insulating member 201 can be an insulating adhesive. In this way, the fourth insulating member 201 can also achieve a fixed connection between the electrode E1 and the second metal member 210, preventing the electrode E1 from falling off the second metal member 210.

[0245] In some feasible embodiments, the third insulating element 220 may include the second plastic element, that is, at least a portion of the material of the third insulating element 220 is plastic.

[0246] In some embodiments of this application, the second plastic part may constitute the above-described... Figure 17A , Figure 17B or Figure 20 Any one or more of the fourth part 221 and the fifth part 222 in the illustrated embodiment, that is, any one or more of the fourth part 221 and the fifth part 222, can be made of plastic.

[0247] In some embodiments of this application, the second plastic part and the second metal part 210 can be an integral structure. For details, please refer to the above description of the embodiments in which the first plastic part and the first metal part 110 are an integral structure, which will not be repeated here.

[0248] In some embodiments of this application, the dimension of the second plastic part along the X1 direction can be greater than or equal to 0.2 mm, for example, 0.2 mm, 0.3 mm, 0.4 mm or 0.5 mm, so that the second plastic part can have a better insulation effect.

[0249] In some embodiments of this application, the third insulating element 220 may also include a second sealant.

[0250] Specifically, Figure 21A This invention illustrates an exemplary configuration of the second sealant 224 of the third insulating member 220 in an embodiment of this application. Figure 21B The detection device 10 in the embodiment of this application is shown. Figure 21A A magnified view of a portion of area A4 in the image. Figure 21C The detection device 10 in the embodiment of this application is shown. Figure 21A The second enlarged view of the A4 area shows a partial view of the region. Figure 21C The second sealant 224 is not shown in the diagram.

[0251] In some embodiments of this application, the second sealant 224 may be formed using a dispensing process.

[0252] refer to Figures 21A to 21C The third insulating component 220 may include a second plastic component 223 and a second sealant 224. The second plastic component 223 surrounds the electrode E1, and the second sealant 224 fills the space between the second plastic component 223 and the electrode E1. The structural form of the gap section between the second plastic component 223 and the electrode E1 is the same as described above. Figures 9A to 9C In the embodiment shown, the gap section G0 between the inner wall M11 of the groove structure 111 and the electrode E1 is essentially the same, and will be briefly described below.

[0253] A third gap G3 and a fourth gap G4 may be provided between the second plastic component 223 and the electrode E1. The third gap G3 and the fourth gap G4 may be provided along the Z1 direction. Furthermore, the width of the third gap G3 is greater than the width of the fourth gap G4. The width of the third gap G3 can be the dimension of the third gap G3 along the X1 direction, and the width of the fourth gap G4 can be the dimension of the fourth gap G4 along the X1 direction.

[0254] In this way, the second sealant 224 can be effectively guided to fully fill the space between the second plastic part 223 and the electrode E1, thereby further enhancing the insulation effect between the second plastic part 223 and the electrode E1.

[0255] Similarly, in some embodiments of this application, during the filling of the second sealant 224, an excessive amount of the second sealant 224 may be applied to ensure that the second sealant 224 is more fully filled between the second plastic part 223 and the electrode E1, thereby further enhancing the insulation effect.

[0256] In some embodiments of this application, a second sealant 224 may also be filled between the second metal part 210 and the electrode E1. Correspondingly, an insulating protrusion 114 may also be provided between the second metal part 210 and the electrode E1. For details, please refer to the above. Figures 9A to 9C The description of the insulating protrusion 114 in the text will not be repeated here.

[0257] In some feasible solutions, air and / or insulating ink may be provided between the third insulator 220 and the side F3 of the electrode E1 to further improve the insulation reliability between the third insulator 220 and the electrode E1.

[0258] Among them, an air insulation scheme is provided between the third insulating member 220 and the side F3 of the electrode E1, which is consistent with the above. Figure 11 and Figure 12 The embodiment shown has essentially the same solution of providing air between the support 100 and the side F3 of the electrode E1, therefore the above can be referred to. Figure 11 and Figure 12 The relevant descriptions in the illustrated embodiments will not be repeated here.

[0259] An insulating solution with insulating ink is provided between the third insulating element 220 and the side surface F3 of the electrode E1, which is consistent with the above-mentioned insulation scheme. Figure 13A and Figure 13B The embodiment shown uses an insulating ink between the support 100 and the side F3 of the electrode E1, which is essentially the same as the above-described solution. Figure 13A and Figure 13B The relevant descriptions in the illustrated embodiments will not be repeated here.

[0260] In some feasible solutions, by rationally designing the layout of each conductive layer in electrode E1, the insulation reliability between electrode E1 and the second metal component 210 and / or the third insulating component 220 can be further improved without the need for additional insulating components or insulating media. Therefore, compared to the above... Figure 2A The plastic bracket 11 shown can effectively save layout space to meet the insulation requirements of small layout spaces.

[0261] The arrangement of each conductive layer in electrode E1 is the same as described above. Figures 14A to 16C The electrode E1 in the illustrated embodiment is essentially the same, therefore it can be referred to the above. Figures 14A to 16C The relevant descriptions in the illustrated embodiments will not be repeated here.

[0262] It is understood that the above insulation solutions can be combined arbitrarily or implemented individually. This application does not impose specific limitations on this, as long as the insulation requirements are met. For example, in some embodiments, the third insulating member 220 may include the second plastic member 223, and insulating ink is provided between the third insulating member 220 and the side surface F3 of the electrode E1. As another example, in some other embodiments, air is provided between the third insulating member 220 and the side surface F3 of the electrode E1, and, as... Figure 14A and Figure 14B As shown, electrode E1 may include a first conductive layer F11, a second conductive layer F21 and a third conductive layer F31. The first conductive layer F11 and the second conductive layer F21 can be connected through the third conductive layer F31. The ratio between the area of ​​the third conductive layer F31 and the side surface F3 of electrode E1 can be 0.001 to 0.1.

[0263] This application also provides an electronic device, which may include a metal casing and a detection device, wherein the detection device is mounted on the metal casing. The detection device may be as described above. Figures 3A to 21C Any of the detection devices 10 shown in the embodiments can be referred to above.
