However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0059] In the description of this application, it should be understood that if terms such as "thickness", "upper", "lower", "front", "rear", "inner", "outer" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0060] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0061] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0062] It should be noted that if a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component. If a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
[0063] Please refer to Figure 1 This application provides a stacked component 100. The stacked component 100 may include a first transparent substrate 50, a second transparent substrate 60, a first functional layer 10, a second functional layer 20, a charge discharge element 30, and / or an electromagnetic field shielding element 40. The charge discharge element 30 and the electromagnetic field shielding element 40 may be provided simultaneously, or only one of them may be provided.
[0064] Along the thickness direction of the laminated assembly 100, the first transparent substrate 50 and the second transparent substrate 60 can be respectively disposed on both sides of the first functional layer 10. An adhesive layer 70 can be disposed between each transparent substrate and the first functional layer 10 to increase the adhesion between the transparent substrate and the first functional layer 10. The adhesive layer 70 can be made of adhesive materials such as PVB, PU and EVA. The materials used to prepare the first functional layer 10 are not limited to one or a combination of two or more of the following: PDLC (polymer dispersed liquid crystal), GHLC (guest-host effect liquid crystal), EC (electrochromic device), SPD (suspended particle device), LC, LED, heat insulation film, color changing film, light guiding film, display film, etc.
[0065] The second transparent substrate 60 can be arranged parallel to and spaced apart from the first transparent substrate 50. The first functional layer 10 can be disposed between the first transparent substrate 50 and the second transparent substrate 60 and can be used for electrical connection with an external power source. For example, when the alternating current applied to the first functional layer 10 changes, the light transmittance, light absorption, and light reflectance of the first functional layer 10 can change accordingly, thereby changing the color of the first functional layer 10 or changing the temperature of the first functional layer 10, etc.
[0066] The second functional layer 20 can be disposed on the side of the second transparent substrate 60 opposite to the first functional layer 10. The second functional layer 20 can be a conductive layer containing metal, and the conductive layer can be a layer structure containing metal elements, such as a metal film layer. Of course, the conductive layer is not limited to a film layer formed by a metal element such as copper film, but can also be a film layer containing conductive material, composed of continuously distributed materials, or having a grid-like or other spaced structure.
[0067] For example, conductive layers such as silver plating, low-emissivity (LOW-E) layers, heat insulation layers, radiation-resistant layers, sound insulation layers, and light-regulating layers can all be used as secondary functional layers. Among them, the LOW-E layer can be made of various metals and has good heat insulation and light transmittance.
[0068] When a charge-discharging element 30 is provided within the stacked assembly 100, the charge-discharging element 30 can be disposed on the side of the second functional layer 20 facing away from the second transparent substrate 60. One end of the charge-discharging element 30 can be electrically connected to the first functional layer 10, and the other end can be used for grounding. For example, one end of the charge-discharging element 30 can be electrically connected to the first functional layer 10, and the other end can be electrically connected to the ground terminal of the electronic control unit (ECU), or the ground terminal of the charge-discharging element 30 can be directly grounded.
[0069] When an electromagnetic field shielding member 40 is provided in the stacked assembly 100, the electromagnetic field shielding member 40 may be disposed between the first functional layer 10 and the second functional layer 20 or on the side of the second functional layer 20 away from the second transparent substrate 60.
[0070] The following is combined with Figures 1-3 The specific embodiments shown illustrate the above-described stacked component 100.
[0071] In some examples, only the charge-conducting element 30 is provided within the stacked component 100. For example... Figure 1As shown, the charge-conducting element 30 can be disposed on the side of the second functional layer 20 opposite to the second transparent substrate 60 and can be grounded. When an alternating current is applied to the first functional layer 10, the first functional layer 10 can generate an electromagnetic field. Under the action of the electromagnetic field, the second functional layer 20 can generate a potential and thus accumulate charge.
[0072] Since a charge-discharging element 30 is provided on the side of the second functional layer 20 facing away from the second transparent substrate 60, and one end of the charge-discharging element 30 is electrically connected to the first functional layer 10 while the other end can be grounded, the charge accumulated on the second functional layer 20 can be conducted away by the charge-discharging element 30, thereby reducing the amount of charge on the second functional layer 20. The residual charge on the second functional layer 20 is lower than a preset value, so when a user touches the second functional layer 20, there will be no electric shock sensation, which can improve the safety of using the stacked component 100.
[0073] In other examples, the stacked assembly 100 contains only an electromagnetic field shield 40. For example... Figure 2 As shown, the electromagnetic field shield 40 can be disposed between the first functional layer 10 and the second functional layer 20. When an alternating current is applied to the first functional layer 10, because the electromagnetic field shield 40 reduces the probability of the second functional layer 20 generating induced current and electromagnetic field, a large amount of charge will not or will not easily accumulate on the second functional layer 20 under the action of the electromagnetic field shield 40, and there will be no electric shock when the user touches the second functional layer 20.
[0074] In some other examples, the stacked component 100 includes both a charge-conducting element 30 and an electromagnetic field shielding element 40. For example... Figure 3 As shown, the charge discharge member 30 can be disposed on the side of the second functional layer 20 opposite to the second transparent substrate 60 and can be grounded. The electromagnetic field shielding member 40 can be disposed between the first functional layer 10 and the second functional layer 20.
[0075] When an alternating current is applied to the first functional layer 10, the first functional layer 10 can generate an electromagnetic field. Because the electromagnetic field shielding member 40 reduces the probability of the second functional layer 20 generating induced current and electromagnetic field, a large amount of charge will not or will not easily accumulate on the second functional layer 20 under the action of the electromagnetic field shielding member 40. Moreover, since a charge conduction member 30 is provided on the side of the second functional layer 20 facing away from the second transparent substrate 60, one end of the charge conduction member 30 is electrically connected to the first functional layer 10, and the other end can be grounded, the charge accumulated on the second functional layer 20 can be conducted away by the charge conduction member 30, thereby effectively reducing the amount of charge on the second functional layer 20. By reducing the amount of charge accumulated on the second functional layer 20, the risk of electric shock when a user touches the second functional layer 20 is avoided or reduced.
[0076] In summary, by providing a charge discharge element 30 and / or an electromagnetic field shield 40 within the stacked assembly 100, the amount of charge on the second functional layer 20 can be reduced. When a user touches the second functional layer 20, the risk of electric shock can be avoided or reduced, thereby improving the safety of using the stacked assembly 100.
[0077] In practical applications, the sunroof structure of a vehicle can adopt the aforementioned laminated component 100, meaning the sunroof glass structure can utilize the aforementioned laminated component 100. When the laminated component is not equipped with a charge discharge element 30, a 36V AC current can be applied to the first functional layer of the laminated component. At this time, the surface of the second functional layer of the laminated component, after measurement, will generate a voltage of 18.54V. When the laminated component 100 is equipped with a charge discharge element 30, a 36V AC current can be applied to the first functional layer 10 of the laminated component 100. At this time, the surface of the second functional layer 20 of the laminated component 100, after measurement, will generate a voltage of 0.019V.
[0078] Therefore, it can be seen that the large amount of charge accumulated on the second functional layer 20 can be guided to the vehicle body by the charge conduction component 30 and flow to the ground. The amount of charge remaining on the second functional layer 20 is small and not enough to harm the user's body, thus avoiding safety hazards.
[0079] In some embodiments, such as Figure 4 As shown, the charge-conducting component 30 may include a body (not shown in the figure) and a connector structure 32. The body may be disposed in the second functional layer 20. Please refer to [the relevant documentation / reference]. Figure 7 The connector structure 32 may include a charge discharge section 321 and a power supply section 322. One end of the power supply section 322 can be electrically connected to the first functional layer 10, and the other end can be electrically connected to an external power source. One end of the charge discharge section 321 can be electrically connected to the main body, and the other end of the charge discharge section 321 can be grounded or electrically connected to the power supply section 322 to be grounded through the power supply section 322.
[0080] In some examples, the charge extraction section 321 can be electrically connected to the power supply section 322. When one end of the power supply section 322 can be electrically connected to an external power source, the current applied by the external power source can flow through the power supply section 322 to the first functional layer 10. The first functional layer 10 can generate an electromagnetic field, and the second functional layer 20 can accumulate charge under the action of the first functional layer 10. By providing the body of the charge extraction section 321 on the second functional layer 20, with one end of the charge extraction section 321 connected to the body and the other end electrically connected to the power supply section 322, a large amount of charge on the second functional layer 20 can first flow to the body, and then flow through the body sequentially through the charge extraction section 321 and the power supply section 322, and finally flow to the ground through the power supply section 322.
[0081] In other examples, such as Figure 4As shown, the charge extraction section 321 can be electrically connected to the ground terminal of the ECU. When one end of the power supply section 322 can be electrically connected to an external power source, the current applied by the external power source can flow through the power supply section 322 to the first functional layer 10. The first functional layer 10 can generate an electromagnetic field, and the second functional layer 20 can accumulate charge under the action of the first functional layer 10. Because the body of the charge extraction section 321 is disposed on the second functional layer 20, and the charge extraction section 321 can be electrically connected to the ground terminal of the ECU, a large amount of charge on the second functional layer 20 can first flow to the body, then flow through the body through the charge extraction section 321 and the ECU, and finally flow to the ground.
[0082] The above settings expand the configuration options for the charge extraction component 30 without affecting its function, thereby broadening its application range.
[0083] In some embodiments, please refer to Figure 5 The power supply unit 322 includes at least two power supply terminals 3221. One end of each power supply terminal 3221 can be electrically connected to the first functional layer 10, and the other end can be electrically connected to an external power source. One end of the charge discharge unit 321 can be electrically connected to the main body, and the other end can be electrically connected to an external grounding device.
[0084] When one end of the power supply terminal 3221 can be electrically connected to an external power source, the current applied by the external power source can flow to the first functional layer 10 through the power supply terminal 3221. The first functional layer 10 can generate an electromagnetic field, and the second functional layer 20 can accumulate charge under the action of the first functional layer 10. Since the body of the charge extraction section 321 is disposed on the second functional layer 20, and the charge extraction section 321 can be electrically connected to the ground terminal of the ECU, a large amount of charge on the second functional layer 20 can first flow to the body, and then flow through the body through the charge extraction section 321 and the ECU, and finally flow to the ground. The above configuration simplifies the structure of the charge extraction section 321, allowing it to be directly electrically connected to the ECU, etc.
[0085] In some embodiments, such as Figure 6 As shown, the charge-discharging portion 321 may be disposed on the side of the body opposite to the second transparent substrate 60. The charge-discharging portion 321 may include a first conductive portion 3211 and an insulating portion 3212. One end of the first conductive portion 3211 may be electrically connected to the body, and the other end may be used to be electrically connected to an external grounding component. The insulating portion 3212 may cover the exterior of the first conductive portion 3211.
[0086] For example, in Figure 6In the example shown, the first conductive part 3211 can be a cylinder. A layer of insulating material 3212 can be wrapped around one of the circumferentially arranged sides of the cylinder. Another side of the cylinder can be electrically connected to the main body, and the remaining side can be used for electrical connection to an external grounding component (such as an ECU). This configuration simplifies the structure of the charge discharge part 321.
[0087] Please combine Figure 5 and Figure 7 In some embodiments, the power supply unit 322 may include at least two power supply terminals 3221, and the charge discharge unit 321 may include at least one connector 3213. The connector 3213 can be used to electrically connect to an external power source, such as an ECU. The charge discharge unit 321 can electrically connect the connector 3213 and the body, so that the body is grounded via an external power source.
[0088] All power supply terminals 3221 can be electrically connected to connector 3213 at the same end, and the other end can be electrically connected to the opposite ends of the first functional layer 10 in the thickness direction and connector 3213 respectively, so that an external power supply can apply current to the first functional layer 10.
[0089] like Figure 7 As shown, in some examples, a charge-discharging element 30 can be disposed on the surface of the second functional layer 20 opposite to the functional area 11. When discharging the charge-discharging element 30, the body of the charge-discharging element 30 can be bonded to the second functional layer 20 using silver paste or the like, and the connector structure 32 can be bent along the edge of the second functional layer 20, i.e., side routing can be performed along the edge of the stacked assembly 100. Side routing allows the body and the first functional layer 10 to be connected together using the connector structure 32 without affecting the strength of the stacked assembly 100 itself.
[0090] The main arrangement of the connector structure 32 is as follows: the charge output part 321 of the connector structure 32 can be installed on the body, the connector 3213 of the connector structure 32 can be protruding relative to the charge output part 321 so as to be electrically connected to an external power source, and the two power supply terminals 3221 of the connector structure 32 can contact the two surfaces of the first functional layer 10 that are opposite to each other in the thickness direction.
[0091] When the connector 3213 of the connector structure 32 is electrically connected to an external power source (such as an ECU), the external power source can supply power to the first functional layer 10 via the power supply terminal 3221. The second functional layer 20 can also generate charge under the action of the first functional layer 10. However, because the second functional layer 20 has a body, and the body is electrically connected to the connector 3213 through the charge discharge part 321, and the connector 3213 can be grounded to the external power source, most of the charge generated on the second functional layer 20 can be transferred by the connector 3213, etc., to reduce the amount of charge accumulation on the second functional layer 20.
[0092] The above configuration improves the connector structure 32 that supplies power to the first functional layer 10, so that the connector structure 32 can be grounded while supplying power to the first functional layer 10, thereby reducing the amount of charge accumulation on the second functional layer 20 and improving the safety of the stacked component 100 during use.
[0093] Please continue reading. Figure 7 In some embodiments, the first functional layer 10 may include an active area 11 and an adhesive area 12. The adhesive area 12 may be disposed around the edge of the active area 11, and one end of each of the two power supply terminals 3221 may pass through the adhesive area 12 and be electrically connected to opposite ends of the active area 11 in the thickness direction of the laminated assembly 100, respectively.
[0094] For example, such as Figure 7 As shown, the functional region 11 can be fabricated using PDLC, and the bonding region 12 can be fabricated using PVB. The bonding region 12 can be disposed around the edge of the functional region 11. For example, the orthographic projection of the functional region 11 on the first transparent substrate 50 can be rectangular, and the orthographic projection of the bonding region 12 on the first transparent substrate 50 can be annular, and the inner ring of the annular structure is in contact with the functional region 11.
[0095] An adhesive region 12 is provided at the edge of the functional region 11, which improves the adhesion between the entire first functional layer 10 and the two adjacent film layers in the thickness direction of the laminated assembly 100, reducing the probability of cracking between the first functional layer 10 and the two film layers. Furthermore, by electrically connecting the power supply terminal 3221 to the functional region 11 through the adhesive region 12, the adhesive region 12 also improves the connection stability between the power supply terminal 3221 and the functional region 11, reducing the probability of separation between the power supply terminal 3221 and the functional region 11.
[0096] In some embodiments, the body may be a metal component, and the resistance value of the body may be lower than the resistance value of the second functional layer 20. For example, the body may be a conductive copper foil. Silver paste may be coated on the second functional layer 20 to place the body in the silver paste coating area. Because the lower the resistance of a conductor, the lower its impedance, and therefore the stronger the conductivity of the conductor, the charge generated by the second functional layer 20 can be quickly transferred by the charge conduction component 30.
[0097] Please continue reading. Figure 7In some embodiments, a shielding layer 31 is provided on the surface of the body facing away from the second functional layer 20. The shielding layer 31 may be a film layer prepared by ink printing, or a film layer that can provide shielding and insulation. The shielding layer 31 has a connection channel 311. The charge discharge part 321 may be embedded in the connection channel 311. It can also be understood that the shielding layer 31 at least avoids the portion of the charge discharge part 30 that is electrically connected to the body. That is, the shielding layer 31 does not completely cover the surface of the body facing away from the first functional layer 10; a portion of the surface of the body facing away from the first functional layer 10 may be left unshielded by the shielding layer 31.
[0098] For example, Figure 7 The connecting channel 311 shown is not coated with ink; the absence of ink coating is the clearance portion 33. Of course, in other examples, the clearance portion 33 may also be provided protruding relative to the body, but the clearance portion 33 is not coated with ink.
[0099] In this way, the charge on the second functional layer 20 can be transferred to the charge output section 321 through the connection channel 311, thereby accelerating the charge transfer speed on the second functional layer 20.
[0100] In practical applications, for example, when the aforementioned stacked component 100 is installed in a vehicle, because the area where the light-shielding layer is located is equipped with the charge-conducting component 30, when the charge-conducting component 30 is connected to the sheet metal on the vehicle body or the ECU on the vehicle body, the light-shielding layer can shield the sheet metal on the vehicle body to reduce the probability of it being exposed to the user's eyes, thereby improving the visual effect of the stacked component 100 after installation.
[0101] Secondly, since the connection channel 311 allows the charge discharge section 321 to pass through, a clearance section 33 is provided at the connection channel 311, which does not require ink coating. Therefore, compared to coating the entire side of the body with ink, providing the clearance section 33 reduces the amount of ink used.
[0102] In some examples, the charge extraction section 321 may contact the second functional layer 20.
[0103] like Figure 7 As shown, a connection channel 311 can be formed on the main body through a hollowing process. One end of the charge discharge part 321 can pass through the connection channel 311 and be electrically connected to the second functional layer 20, and the other end can be electrically connected to the connector 3213. Because the two ends of the charge discharge part 321 are directly electrically connected to the second functional layer 20 and the connector 3213 respectively, the charge discharge part 321 can be used to quickly and accurately transfer the charge accumulated on the second functional layer 20, thereby improving the speed of charge transfer.
[0104] In some embodiments, such as Figure 5As shown, the connector structure 32 may include a second conductive portion 323. Please refer to the following: Figure 7 The second conductive part 323 may be disposed on the side of the body away from the second functional layer 20. The charge discharge part 321 and the connector 3213, as well as the power supply terminal 3221 and the connector 3213, may be electrically connected via the second conductive part 323.
[0105] When connector 3213 is electrically connected to an external power source, current can flow through connector 3213 to the second conductive part 323, and from the second conductive part 323 to the power supply terminal 3221, and then to the first functional layer 10. Meanwhile, the charge on the second functional layer 20 can flow from the charge discharge part 321 to the second conductive part 323, and then through the second conductive part 323 to connector 3213, finally flowing to the external power source.
[0106] The electrical connection between the power supply terminal 3221 and the connector 3213, and the electrical connection between the charge discharge part 321 and the connector 3213 are achieved by the second conductive part 323, which simplifies the structure of the connector structure 32.
[0107] It should be noted that the structure of the charge output section 321 can be changed according to the actual situation, as long as the charge output section 321 is used to realize the electrical connection between the second functional layer 20 and the connector 3213.
[0108] Please refer to Figure 5 and Figure 7 In some examples, the charge-derived portion 321 may be bent toward the body relative to the second conductive portion 323.
[0109] Alternatively, please refer to Figure 7 and Figure 8 In other examples, the charge-derived portion 321 may be formed by a conductive adhesive portion disposed on the second conductive portion 323, which may be bonded to the body.
[0110] For example, please continue reading Figure 8 The second conductive part 323 may include a housing and a conductor. The conductor may be housed inside the housing, and the charge discharge part 321 and the connector 3213, as well as the power supply terminal 3221 and the connector 3213, may be electrically connected via the conductor. The housing may have a perforated hole, and the charge discharge part 321 may be formed by a conductive adhesive portion, which fills the perforated hole.
[0111] When a large amount of charge accumulates on the second functional layer 20, most of the charge can be transferred to the connector 3213 through the charge discharge section 321. In this way, the connection stability between the second conductive section 323 and the body can be improved without affecting the charge transfer efficiency.
[0112] In some embodiments, such as Figure 9 As shown, the electromagnetic field shielding component 40 also includes an insulating shielding layer 41. The insulating shielding layer 41 may be located on the side of the second functional layer 20 opposite to the first functional layer 10, and the insulating shielding layer 41 at least avoids the portion of the charge discharge component 30 that is electrically connected to the main body. That is, the portion of the charge discharge component 30 that is electrically connected to the main body may not be provided with an insulating shielding layer 41.
[0113] Because the insulating shielding layer 41 acts as a barrier to the second functional layer 20, it reduces the probability that the second functional layer 20 is directly exposed to the air. When a user touches the second functional layer 20, the insulating shielding layer 41 acts as a barrier, thereby reducing the probability that the leakage of charge accumulated on the second functional layer 20 may cause electric shock to the user, thus providing the reliability of the stacked structure.
[0114] It is understood that in some embodiments, such as Figure 10 As shown, the laminated assembly 100 may only have an insulating shielding layer 41. Depending on the actual situation, it may be determined whether to include either the insulating shielding layer 41 or the charge-conducting element 30 in the laminated assembly 100.
[0115] like Figure 11 As shown, in some embodiments, the electromagnetic field shielding component 40 further includes a first shielding layer 42. For example, the first shielding layer 42 may be a metal fiber layer with a high metal content. The first shielding layer 42 may be disposed between the second functional layer 20 and the first functional layer 10. Both ends of the first shielding layer 42 and the first functional layer 10 in the thickness direction of the laminated assembly 100 are used for electrical connection to an external power source, and the voltage direction of the first shielding layer 42 is opposite to the voltage direction of the first functional layer 10. Here, the voltage direction refers to the direction from high potential to low potential.
[0116] For example, the positive terminal of the first shielding layer 42 is electrically connected to the positive terminal of the external power supply, and the negative terminal of the first shielding layer 42 is electrically connected to the negative terminal of the external power supply; while the positive terminal of the first functional layer 10 is electrically connected to the negative terminal of the external power supply, and the negative terminal of the first functional layer 10 is electrically connected to the positive terminal of the external power supply. Thus, the direction of the electromagnetic field generated by the first shielding layer 42 is opposite to the direction of the electromagnetic field generated by the first functional layer 10.
[0117] For example, such as Figure 11 As shown, both ends of the first shielding layer 42 and the first functional layer 10 in the thickness direction of the laminated assembly 100 are used for electrical connection to the same external power supply. The first shielding layer 42 may be disposed between the first transparent substrate 50 and the adhesive layer 70. When the first shielding layer 42 and the first functional layer 10 are powered simultaneously, the current directions of the first shielding layer 42 and the first functional layer 10 are opposite. Therefore, the direction of the electromagnetic field generated by the first shielding layer 42 is opposite to the direction of the electromagnetic field generated by the first functional layer 10.
[0118] Because the induced current generated by the second functional layer 20 is smaller under the influence of the electromagnetic field generated by the first shielding layer 42, the charge accumulated on the second functional layer 20 is also smaller, which can reduce the probability of electric shock when the user touches the second functional layer 20.
[0119] It is easy to understand that the first shielding layer 42 can be set on the side closer to the second functional layer 20 or on the side farther away from the second functional layer 20, as long as it can block the induced current generated by the second functional layer 20.
[0120] like Figure 12 As shown, in some embodiments, only the first shielding layer 42 may be provided in the stacked assembly 100. It may be determined, depending on the actual situation, that one or both of the first shielding layer 42 and the charge discharge member 30 may be provided in the stacked assembly 100.
[0121] In some embodiments, such as Figure 13 As shown, the electromagnetic field shielding component 40 also includes a second shielding layer 43. The second shielding layer 43 may be distributed around the first functional layer 10 and avoids the portion where the charge discharge component 30 is electrically connected to the first functional layer 10. That is, the portion where the charge discharge component 30 is electrically connected to the first functional layer 10 is not provided with the second shielding layer 43.
[0122] The second shielding layer 43 can be made of a material that can shield electric fields to reduce the probability of induced current generated by the second functional layer 20, thereby reducing the amount of charge accumulated on the second functional layer 20 and reducing the probability of electric shock when the user touches the second functional layer 20.
[0123] It is understandable that the second shielding layer 43 can be configured in ways including but not limited to... Figure 7 As shown, the second shielding layer 43 may also cover only a portion of the first functional layer 10.
[0124] like Figure 14 As shown, in some embodiments, only the second shielding layer 43 may be provided in the stacked assembly 100. It may be determined, depending on the specific circumstances, that one or both of the second shielding layer 43 and the charge discharge element 30 may be provided in the stacked assembly 100.
[0125] Furthermore, some embodiments of this application also provide a connector structure 32 for a multilayer assembly. The connector structure 32 may include a charge discharge section 321 and a power supply section 322. One end of the power supply section 322 can be electrically connected to the first functional layer 10 of the multilayer assembly 100, and the other end can be electrically connected to an external power source. One end of the charge discharge section 321 can be electrically connected to the body of the multilayer assembly 100, and the other end of the charge discharge section 321 can be grounded or electrically connected to the power supply section 322 to be grounded through the power supply section 322.
[0126] The above settings expand the configuration options for the charge extraction component 30 without affecting its function, thereby broadening its application range.
[0127] In some embodiments, please refer to Figure 5 The power supply unit 322 includes at least two power supply terminals 3221. One end of each power supply terminal 3221 can be used to electrically connect to the first functional layer 10, and the other end can be used to electrically connect to an external power source. One end of the charge discharge unit 321 can be used to electrically connect to the body of the stacked assembly 100, and the other end can be used to electrically connect to an external grounding component.
[0128] When one end of the power supply terminal 3221 can be electrically connected to an external power source, the current applied by the external power source can flow to the first functional layer 10 through the power supply terminal 3221. The first functional layer 10 can generate an electromagnetic field, and the second functional layer 20 can accumulate charge under the action of the first functional layer 10. Since the body of the charge discharge section 321 is disposed on the second functional layer 20, and the charge discharge section 321 can be electrically connected to the ground terminal of the ECU, a large amount of charge on the second functional layer 20 can first flow to the body, and then flow through the body through the charge discharge section 321 and the ECU, and finally flow to the ground.
[0129] The above configuration simplifies the structure of the charge output section 321, allowing it to be directly electrically connected to the ECU.
[0130] Please combine Figure 5 and Figure 7 In some embodiments, the power supply unit 322 may include at least two power supply terminals 3221, and the charge discharge unit 321 may include at least one connector 3213. The connector 3213 can be used to electrically connect to an external power source, such as an ECU. The charge discharge unit 321 can electrically connect the connector 3213 and the body, so that the body of the stacked assembly 100 is grounded via an external power source.
[0131] One end of the power supply terminal 3221 can be electrically connected to the connector 3213, and the other end can be electrically connected to the opposite ends of the first functional layer 10 in the thickness direction, so that an external power supply can apply current to the first functional layer 10.
[0132] With this configuration, the aforementioned connector structure 32 can be grounded while simultaneously applying current to the first functional layer 10 via an external power supply.
[0133] Furthermore, some embodiments of this application also provide a vehicle. The vehicle includes a body and the aforementioned laminated component 100. The laminated component 100 can be mounted on the body. Because the vehicle includes the laminated component 100, it possesses the functions and beneficial effects of the laminated component 100 provided in the above embodiments, which will not be elaborated further here.
[0134] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0135] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
