Technical Field

[0003] The present application relates to the field of laminated components, and in particular to a laminated component, a joint structure for a laminated component, and a vehicle. Background Art

[0004] The stacked module is equipped with functional elements that can functionalize the stacked module, so that the stacked module can have functions such as lighting, privacy (such as electrochromic), video and heating. Among them, these functional elements are usually installed inside the stacked module.

[0005] Currently, stacked components are widely used to impart different functions to functional elements by applying current. However, when the functional elements are energized, a large amount of charge can accumulate on the surface of the stacked components. When a user touches the surface of the stacked components, they experience an electric shock. Therefore, using such stacked components presents certain safety risks.

[0006] Summary of the Invention

[0007] Based on this, it is necessary to provide a laminated assembly to address the problem that the second functional layer of existing laminated assemblies has an electric shock feeling when in use, thereby posing a safety hazard. The laminated assembly can eliminate the electric shock feeling of the second functional layer and improve the safety of the laminated assembly when in use.

[0008] In a first aspect, the present application provides a laminated component, comprising a laminated body, wherein the laminated body comprises a first transparent substrate, a second transparent substrate, a first functional layer, a second functional layer, and at least one of a charge derivation element and an electromagnetic field shielding element:

[0009] a first functional layer, disposed between the first transparent substrate and the second transparent substrate, and configured to be electrically connected to an external power source;

[0010] a second functional layer disposed on a side of the second transparent substrate facing away from the first functional layer;

[0011] The charge derivation element is arranged on a side of the second functional layer away from the second transparent substrate, one end of the charge derivation element is electrically connected to the first functional layer, and the other end of the charge derivation element is grounded;

[0012] The electromagnetic field shielding component is arranged between the first functional layer and the second functional layer, or the electromagnetic field shielding component is arranged on a side of the second functional layer away from the second transparent substrate;

[0013] or,

[0014] The laminate body also includes a second shielding layer, which is arranged on the side of the second functional layer away from the second transparent substrate. The second shielding layer is arranged along the periphery of the laminate body. One end of the charge exporting element is electrically connected to at least part of the second shielding layer, and the other end of the charge exporting element is used for grounding.

[0015] Providing at least one of a charge derivation component and an electromagnetic field shielding component in the laminated component can reduce the amount of charge on the second functional layer. When the user touches the second functional layer, the risk of electric shock is avoided or reduced, thereby improving the safety of the laminated component when in use.

[0016] If the laminated body is provided with a second shielding layer, applying an alternating current to the laminated body generates an electromagnetic field within the laminated body. Under the influence of this electromagnetic field, an electric potential is generated on the side where the second shielding layer is located, and charge accumulates. Because the second shielding layer is electrically connected to the charge decoupling element, which is in turn grounded, a large amount of charge accumulated on the side where the second shielding layer is located can be conducted away by the charge decoupling element, thereby reducing the amount of charge on the side where the second shielding layer is located.

[0017] When a user touches the side of the laminate body provided with the second shielding layer, the user does not experience an electric shock because the amount of charge remaining on the side provided with the second shielding layer is lower than a preset value. This improves the safety of the laminate assembly when used in devices such as automobiles.

[0018] Secondly, the second shielding layer can also shield the mounting area of ​​the laminated assembly (such as the body sheet metal), beautifying the installation effect of the laminated assembly and preventing the body sheet metal from being directly exposed to the user's line of sight. In addition, the second shielding layer can also block some ultraviolet rays to reduce the direct impact of ultraviolet rays on the charge decoupling element.

[0019] In a possible embodiment, when the charge derivation element is electrically connected to the first functional layer, the charge derivation element includes a body and a connector structure, and the body is disposed on the second functional layer;

[0020] The connector structure includes a charge derivation part and a power supply part, one end of the power supply part is used to be electrically connected to the first functional layer, and the other end of the power supply part is used to be electrically connected to an external power supply; one end of the charge derivation part is electrically connected to the main body, and the other end of the charge derivation part is used for grounding, or the other end of the charge derivation part is electrically connected to the power supply part to be grounded through the power supply part.

[0021] The above-mentioned setting can expand the setting mode of the charge derivation component without affecting the function of the charge derivation component, thereby expanding the scope of use of the charge derivation component.

[0022] In a possible embodiment, the power supply part includes at least two power supply terminals, one end of the power supply terminal is electrically connected to the first functional layer, and the other end of the power supply terminal is used to electrically connect to an external power supply, one end of the charge derivation part is electrically connected to the main body, and the other end of the charge derivation part is used to electrically connect to an external grounding member.

[0023] The above arrangement simplifies the structure of the charge derivation unit, allowing it to be directly electrically connected to the ECU, etc.

[0024] In a possible embodiment, the charge derivation portion is arranged on the side of the main body away from the second transparent substrate, and the charge derivation portion includes a first conductive portion and an insulating portion, one end of the first conductive portion is electrically connected to the main body, and the other end of the first conductive portion is used to be electrically connected to an external grounding member, and the insulating portion wraps the outside of the first conductive portion.

[0025] This arrangement can simplify the structure of the charge extraction portion.

[0026] In one possible embodiment, the power supply unit includes at least two power supply terminals, the charge extraction unit includes at least one connector, the connector is used to electrically connect to an external power source, and the charge extraction unit is electrically connected to the connector and the body so that the body is grounded via the external power source.

[0027] One end of the power supply terminal is electrically connected to the connector, and the other end of the power supply terminal is electrically connected between the opposite ends of the first functional layer in the layer thickness direction and the connector, so that the external power supply applies current to the first functional layer.

[0028] By improving the joint structure that supplies power to the first functional layer, the joint structure can be grounded while supplying power to the first functional layer, thereby reducing the amount of charge accumulation on the second functional layer and improving the safety of the stacked component during use.

[0029] In a possible embodiment, a first shielding layer is provided on a surface of the body facing away from the second functional layer, a connecting channel is opened in the first shielding layer, and the charge derivation portion is embedded in the connecting channel.

[0030] Because the charge decoupling element is installed in the area where the first shielding layer is located, when the charge decoupling element is connected to the body sheet metal or the ECU on the body, the first shielding layer can shield the body sheet metal from the user, thereby improving the visual effect of the installed laminated assembly. Charge on the second functional layer can be transferred to the charge decoupling element through the connection channel, thereby accelerating the transfer of charge from the second functional layer.

[0031] In a possible embodiment, the charge decoupling portion is in contact with the second functional layer.

[0032] Because the two ends of the charge extraction portion are directly electrically connected to the second functional layer and the connector respectively, the charge extraction portion can be used to quickly and accurately transfer the charges accumulated on the second functional layer, thereby increasing the speed of charge transfer.

[0033] In a possible embodiment, the joint structure further includes a second conductive portion, and the second conductive portion is disposed on a side of the body away from the second functional layer;

[0034] The charge extraction portion and the connector, as well as the power supply terminal and the connector, are electrically connected via the second conductive portion.

[0035] The electrical connection between the power supply terminal and the connector, and the electrical connection between the charge extraction portion and the connector are achieved through the second conductive portion, which can simplify the structure of the connector structure.

[0036] In a possible embodiment, the charge derivation portion is bent relative to the second conductive portion toward the main body; or, the charge derivation portion is formed by a conductive adhesive portion provided on the second conductive portion, and the conductive adhesive portion is bonded to the main body.

[0037] When a large amount of charge accumulates on the second functional layer, most of the charge can be transferred to the connector through the charge extraction portion. This improves the connection stability between the second conductive portion and the body without affecting the charge transfer efficiency.

[0038] In a possible embodiment, the second conductive portion includes a housing and a conductor, the conductor is accommodated inside the housing, and the charge extraction portion and the connector, as well as the power supply terminal and the connector, are electrically connected via the conductor;

[0039] A first hollow hole is provided on the shell, and the charge derivation portion is formed by a conductive adhesive portion, which is filled in the first hollow hole.

[0040] In this way, the connection stability between the second conductive portion and the body can be improved without affecting the charge transfer efficiency.

[0041] In a possible embodiment, the body is a metal part, and the resistance value of the body is smaller than the resistance value of the second functional layer.

[0042] Because the lower the resistance of the conductor, the lower its impedance is, and the stronger the conductivity of the conductor is, the charges generated by the second functional layer can be quickly transferred by the charge lead-out element.

[0043] In a possible embodiment, the first functional layer includes an active area and a bonding area. The bonding area is arranged around the edge of the active area. One end of each of the two power supply terminals passes through the bonding area and is electrically connected to the opposite ends of the active area in the layer thickness direction of the stacked component.

[0044] Providing an adhesive zone at the edge of the active area improves the adhesion between the first functional layer and the two adjacent film layers across the thickness of the laminate, reducing the likelihood of cracking between the first functional layer and the two film layers. Furthermore, by allowing the power supply terminals to pass through the adhesive zone and electrically connect to the active area, the adhesive zone also improves the connection stability between the power supply terminals and the active area, reducing the likelihood of separation between the terminals and the active area.

[0045] In a possible embodiment, the stacked component further includes a fourth shielding layer, which is disposed on a side of the body away from the second functional layer, and the fourth shielding layer at least avoids a portion where the charge derivation element is electrically connected to the body.

[0046] When the above-mentioned laminated component is assembled on a vehicle, because the charge derivation component is installed in the area where the fourth shielding layer is located, when the charge derivation component is connected to the sheet metal on the vehicle body or the ECU on the vehicle body, the fourth shielding layer can shield the vehicle body sheet metal to reduce the probability of being exposed to the user, thereby beautifying the visual effect after the laminated component is installed.

[0047] When one end of the charge derivation member is electrically connected to at least a portion of the second shielding layer, the laminated body is mounted on the to-be-mounted member via the charge derivation member, and the charge derivation member is grounded via the to-be-mounted member.

[0048] In a possible embodiment, the charge lead-out element is adhesively connected between the component to be mounted and the laminate body.

[0049] In this way, the installation method of the charge derivation component can be simplified, making it easier for users to operate.

[0050] In a possible embodiment, the charge derivation element is a conductive adhesive element.

[0051] When the laminated component is mounted on a body sheet metal part, the assembly of the laminated component can be completed quickly. Moreover, if the laminated component falls off the body, it can be easily reinstalled. In addition, the low price and easy availability of conductive adhesive components can also reduce the production cost of the laminated component.

[0052] In a possible embodiment, the laminated component further includes a first edging member, which is located on one side of the second shielding layer in the layer thickness direction; a second hollow hole is constructed on the first edging member, and a charge derivation member is provided in the second hollow hole.

[0053] When the laminated component is provided with a first edging member, a second hollow hole may be opened on the first edging member, and a charge lead-out member may be filled in the second hollow hole so that when alternating current is applied to the laminated component, the charge lead-out member can be used to conduct away a large amount of charge accumulated on the second functional layer.

[0054] In a possible embodiment, the laminated assembly further includes a second edging piece, which is coated on the outer peripheral wall of the laminated body and connected to the first edging piece.

[0055] The second edge member can be used to more effectively protect the laminated component, so as to further reduce the probability of cracks and water ingress at the edge of the laminated component, thereby enhancing the strength of the laminated component.

[0056] In a possible embodiment, the second functional layer is located on the side of the second shielding layer away from the charge derivation element, and the second functional layer and the second shielding layer are staggered in the layer thickness direction; wherein the second functional layer and the second shielding layer are electrically connected.

[0057] By grounding the charge decoupling element, the charge accumulated on the second functional layer can be conducted away by the charge decoupling element, reducing the charge on the second functional layer. When a user touches the second functional layer, the residual charge on the second functional layer is lower than a preset value, so the user does not experience an electric shock, thereby improving the safety of the stacked component.

[0058] Secondly, the second shielding layer can also shield the mounting area of ​​the laminated assembly (such as the body sheet metal), beautifying the laminated assembly installation effect and preventing the body sheet metal from being directly exposed to the user's line of sight. In addition, the second shielding layer 80 can also block some ultraviolet rays to reduce the impact of ultraviolet rays on the charge derivation element.

[0059] In a possible embodiment, the laminate body further includes a third shielding layer, the third shielding layer is located on a side of the first transparent substrate facing the first functional layer, and the third shielding layer is disposed along a periphery of the laminate body.

[0060] In this way, the third shielding layer can also shield the charge derivation components and the body sheet metal components, so as to beautify the visual effect after the laminated components are installed.

[0061] In a possible embodiment, a projection of the third shielding layer along the layer thickness direction covers the charge derivation element, and the third shielding layer is an insulating element.

[0062] In this way, not only the difficulty of obtaining the third shielding layer is reduced, but also the covering effect on the charge derivation components and body sheet metal parts is improved.

[0063] In a possible embodiment, a projection of the third shielding layer along the layer thickness direction covers the charge derivation element.

[0064] In this way, the covering effect of the charge lead-out parts and the body sheet metal parts can be improved.

[0065] In a possible embodiment, the third shielding layer is an insulating member.

[0066] In this way, the difficulty of obtaining the third shielding layer can be reduced.

[0067] In a possible embodiment, the electromagnetic field shielding element further includes an insulating shielding layer, which is located on a side of the second functional layer facing away from the first functional layer, and the insulating layer at least avoids a portion where the charge derivation element is electrically connected to the body.

[0068] When a user touches the second functional layer, there is an insulating shielding layer in between, which reduces the probability that the charge accumulated on the second functional layer will leak out and cause an electric shock to the user, thereby improving the reliability of the stacked component.

[0069] In a possible embodiment, the electromagnetic field shielding element further includes a first shielding layer, and the first shielding layer is disposed between the second functional layer and the first functional layer;

[0070] Both ends of the first shielding layer and the first functional layer in the layer thickness direction of the stacked component are used to electrically connect to an external power supply, and a voltage direction of the first shielding layer is opposite to a voltage direction of the first functional layer.

[0071] Since the induced current generated by the second functional layer is smaller under the action of the electromagnetic field generated by the first shielding layer, the charge accumulated on the second functional layer is also smaller, which can reduce the probability of electric shock induction when the user touches the second functional layer.

[0072] In a possible embodiment, both ends of the first shielding layer and the first functional layer in the layer thickness direction of the stacked component are used to electrically connect to the same external power source.

[0073] When power is supplied to the first shielding layer and the first functional layer simultaneously, the currents flowing into them are directed in opposite directions. Therefore, the electromagnetic field generated by the first shielding layer is directed in the opposite direction to that generated by the first functional layer. Because the electromagnetic field generated by the first shielding layer induces a smaller current in the second functional layer, less charge accumulates in the second functional layer, reducing the likelihood of an electric shock when a user touches the second functional layer.

[0074] In a possible embodiment, the electromagnetic field shielding element further includes a second shielding layer, which is distributed around the first functional layer. The second shielding layer avoids a portion where the charge derivation element is electrically connected to the first functional layer.

[0075] The second shielding layer can reduce the probability of induced current generated by the second functional layer, thereby reducing the amount of charge accumulated on the second functional layer, and reducing the probability of electric shock induction when the user touches the second functional layer.

[0076] In the second aspect, the present application provides a joint structure for a stacked component, the joint structure including the above-mentioned charge derivation part and the power supply part, one end of the power supply part is used to be electrically connected to the first functional layer of the stacked component, and the other end of the power supply part is used to be electrically connected to an external power supply; one end of the charge derivation part is used to be electrically connected to the body of the stacked component, and the other end of the charge derivation part is used to be grounded or electrically connected to the power supply part to be grounded through the power supply part.

[0077] The above-mentioned setting can expand the setting mode of the charge derivation component without affecting the function of the charge derivation component, thereby expanding the scope of use of the charge derivation component.

[0078] In a possible embodiment, the power supply part includes at least two power supply terminals, one end of the power supply terminal is used to electrically connect to the first functional layer, and the other end of the power supply terminal is used to electrically connect to an external power source, one end of the charge derivation part is used to electrically connect to the body of the stacked component, and the other end of the charge derivation part is used to electrically connect to an external grounding member.

[0079] The above arrangement simplifies the structure of the charge derivation unit, allowing it to be directly electrically connected to the ECU, etc.

[0080] In one possible embodiment, the power supply unit includes at least two power supply terminals, the charge extraction unit includes at least one connector, the connector is used to electrically connect to an external power source, and the charge extraction unit is electrically connected to the connector and the body of the stacked assembly, so that the body of the stacked assembly is grounded via the external power source.

[0081] One end of the power supply terminal is electrically connected to the connector, and the other end of the power supply terminal is used to electrically connect to two opposite ends of the first functional layer in the layer thickness direction, so that an external power source applies current to the first functional layer.

[0082] With such a configuration, the connector structure can be electrically connected to an external power source to apply current to the first functional layer while also being grounded.

[0083] A vehicle comprises a vehicle body and the above-mentioned layered assembly, wherein the layered assembly is mounted on the vehicle body.

[0084] Embodiments of the present application provide a laminated assembly, a joint structure for the laminated assembly, and a vehicle. The laminated assembly may be provided with at least one of a charge deflector and an electromagnetic field shielding element. The charge deflector may be provided on a side of the second functional layer facing away from the first functional layer and may be grounded. The electromagnetic field shielding element may be provided between the first and second functional layers, or on a side of the second functional layer facing away from the first functional layer.

[0085] When current is applied to the first functional layer, if the stacked component is equipped with a charge conduction element, and the charge conduction element is provided on the side of the second functional layer facing away from the first functional layer, with one end of the charge conduction element electrically connected to the first functional layer and the other end grounded, charge accumulated on the second functional layer can be conducted away by the charge conduction element, thereby reducing the amount of charge on the second functional layer. Because the residual charge on the second functional layer is lower than a preset value, the risk of electric shock when a user touches the second functional layer is avoided or reduced.

[0086] If the laminated component is provided with an electromagnetic field shielding component, a large amount of charge will not accumulate on the second functional layer under the action of the electromagnetic field shielding component. When the user touches the second functional layer, there will be no electric shock, thereby improving the safety of the laminated component when in use.

[0087] Furthermore, the laminated body may be provided with a second shielding layer. When an alternating current is applied to the laminated body, an electromagnetic field is generated within the laminated body. Under the influence of this electromagnetic field, an electric potential is generated on the side where the second shielding layer is located, thereby collecting charge. Because the second shielding layer is electrically connected to the charge decoupling element, which is in turn grounded, a large amount of charge accumulated on the side where the second shielding layer is located can be conducted away by the charge decoupling element, thereby reducing the amount of charge on the side where the second shielding layer is located.

[0088] When a user touches the side of the laminate body provided with the second shielding layer, the user does not experience an electric shock because the amount of charge remaining on the side provided with the second shielding layer is lower than a preset value. This improves the safety of the laminate assembly when used in devices such as automobiles.

[0089] The second shielding layer can also shield the mounting area of ​​the laminated assembly (such as the body sheet metal), beautifying the installation effect and preventing the body sheet metal from being directly exposed to the user. Furthermore, the second shielding layer can partially block ultraviolet rays to reduce the risk of direct ultraviolet rays reaching the charge decoupling element and affecting it.

[0120] The first functional layer 10 is arranged between the first transparent substrate 50 and the second transparent substrate 60, and is used to be electrically connected to an external power supply; the second functional layer 20 is arranged on the side of the second transparent substrate 60 away from the first functional layer 10; the charge derivation element 30 is arranged on the side of the second functional layer 20 away from the second transparent substrate 60, one end of the charge derivation element 30 is electrically connected to the first functional layer 10, and the other end of the charge derivation element 30 is used for grounding; the electromagnetic field shielding element 40 is arranged between the first functional layer 10 and the second functional layer 20 or, the electromagnetic field shielding element 40 is arranged on the side of the second functional layer 20 away from the second transparent substrate 60.

[0121] Alternatively, the laminate body 100 further includes a second shielding layer 80. The second shielding layer 80 is disposed on a side of the second functional layer 20 facing away from the second transparent substrate 60. The second shielding layer 80 is disposed along the periphery of the laminate body 100. One end of the charge derivation element 30 is electrically connected to at least a portion of the second shielding layer 80, and the other end of the charge derivation element 30 is grounded.

[0122] The first transparent substrate 50 and the second transparent substrate 60 can both be ordinary glass. Along the layer thickness direction of the stacked component 1000, the first transparent substrate 50 and the second transparent substrate 60 can be respectively arranged on both sides of the first functional layer 10. An adhesive layer 70 can be arranged between each transparent substrate and the first functional layer 10 to increase the bonding effect between the transparent substrate and the first functional layer 10. The adhesive layer 70 may be made of adhesive materials such as polyvinyl butyral (PVB), polyurethane (PU), and ethylene-vinyl acetate copolymer (EVA). The material for making the first functional layer 10 is not limited to one or a combination of two or more of polymer dispersed liquid crystal (PDLC), guest-host effect liquid crystal (GHLC), electrochromic device (ECD), suspended particle device (SPD), LC, light-emitting diode (LED), thermal insulation film, color-changing film, light-guiding film, display film, etc.

[0123] 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 to electrically connect to an external power source. For example, when the alternating current applied to the first functional layer 10 changes, the light transmittance, light absorptivity, and light reflectivity of the first functional layer 10 can also change accordingly, thereby changing the color of the first functional layer 10 or changing the temperature of the first functional layer 10.

[0124] The second functional layer 20 can be disposed on the side of the second transparent substrate 60 facing away from the first functional layer 10. The second functional layer 20 can be a conductive layer containing a metal. The conductive layer can have a layer structure containing a metal element, such as a metal film layer. Of course, the conductive layer is not limited to a film layer formed of a single metal element, such as a copper film. It can also be a film layer containing a conductive material, composed of a continuously distributed material, or having a grid-like structure.

[0125] For example, silver-plated layers, Low-E (Low Emissivity) layers, and other conductive insulation layers, radiation-resistant layers, sound-insulating layers, and dimming layers can all be used as the second functional layer. Low-E layers can be made of a variety of metals and offer excellent thermal insulation and light transmittance.

[0126] The second shielding layer 80 can be an ink layer coated with ink, or a film layer coated with other coatings. The layer thickness direction can be understood as the layer thickness direction of the stacked assembly 1000. For example, if the orthographic projection of the stacked body 100 in the layer thickness direction is a rectangle, the orthographic projection of the second shielding layer 80 in the layer thickness direction can coincide with the outline of the rectangle.

[0127] When a charge derivation element 30 is provided within the stacked assembly 1000, it can be positioned on the side of the second functional layer 20 facing away from the second transparent substrate 60. One end of the charge derivation element 30 can be electrically connected to the first functional layer 10, while the other end of the charge derivation element 30 can be grounded. For example, one end of the charge derivation element 30 can be electrically connected to the first functional layer 10, while the other end can be electrically connected to the ground of an electronic control unit (ECU), or the ground of the charge derivation element 30 can be directly connected to ground.

[0128] When the electromagnetic shielding member 40 is provided in the stacked assembly 1000 , the electromagnetic shielding member 40 may be provided between the first functional layer 10 and the second functional layer 20 , or on a side of the second functional layer 20 facing away from the second transparent substrate 60 .

[0129] The above-mentioned stacked assembly 1000 will be described below with reference to the specific embodiments shown in FIG. 1 to FIG. 3 , FIG. 9 and FIG. 10 .

[0130] In some examples, only the charge decoupling element 30 is provided within the stacked assembly 1000. As shown in Figure 1 , the charge decoupling element 30 can be disposed on the side of the second functional layer 20 facing away from 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 generates an electromagnetic field. Under the influence of this electromagnetic field, the second functional layer 20 generates an electric potential, thereby collecting charge.

[0131] Because the charge decoupling element 30 is disposed on the side of the second functional layer 20 facing away from the second transparent substrate 60, and one end of the charge decoupling element 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 decoupling element 30, thereby reducing the amount of charge on the second functional layer 20. The amount of residual charge on the second functional layer 20 is lower than a preset value, and when a user touches the second functional layer 20, there is no electric shock, thereby improving the safety of the stacked assembly 1000 during use.

[0132] In other examples, only the electromagnetic shielding element 40 is provided within the laminated assembly 1000. As shown in FIG2 , the electromagnetic shielding element 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, the electromagnetic shielding element 40 reduces the probability of induced current and electromagnetic field generation in the second functional layer 20. Therefore, due to the electromagnetic shielding element 40, a large amount of charge does not or is not likely to accumulate on the second functional layer 20. Therefore, when a user touches the second functional layer 20, there is no electric shock.

[0133] In yet other examples, the stacked assembly 1000 includes both a charge decoupling element 30 and an electromagnetic field shielding element 40. As shown in FIG3 , the charge decoupling element 30 can be disposed on the side of the second functional layer 20 facing away from the second transparent substrate 60 and can be grounded. The electromagnetic field shielding element 40 can be disposed between the first functional layer 10 and the second functional layer 20.

[0134] 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 element 40 reduces the probability of the second functional layer 20 generating an induced current and an electromagnetic field, the electromagnetic field shielding element 40 prevents or reduces the accumulation of a large amount of charge on the second functional layer 20. Furthermore, since a charge decoupling element 30 is provided on the side of the second functional layer 20 facing away from the second transparent substrate 60, with one end of the charge decoupling element 30 electrically connected to the first functional layer 10 and the other end grounded, the charge accumulated on the second functional layer 20 can be conducted away by the charge decoupling element 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.

[0135] In yet other examples, as shown in FIG9 , when the entire second shielding layer 80 is a conductive layer, one end of the charge decoupling element 30 can be electrically connected to the second shielding layer 80, and the other end can be electrically connected to a ground element (e.g., a vehicle body sheet metal 400). When alternating current is applied to the laminated assembly 1000, the charge accumulated on the laminated body 100 is first transferred to the second shielding layer 80, and then to the charge decoupling element 30, where it is discharged.

[0136] As shown in FIG10 , in other embodiments, when only a portion of the second shielding layer 80 is conductive, in other words, the second shielding layer 80 can be divided into two regions, one of which is a conductive region 81 and the other is an insulating region 82. One end of the charge derivation element 30 can be electrically connected to the conductive region 81 of the second shielding layer 80, and the other end of the charge derivation element 30 can be connected to the vehicle body sheet metal 400.

[0137] When alternating current is applied to the stacked component 1000 , a large amount of charges accumulated on the stacked body 100 may first accumulate in the conductive area 81 of the second shielding layer 80 , and then be transferred to the charge derivation element 30 through the conductive area 81 , and then be derivationed by the charge derivation element 30 .

[0138] In summary, by providing at least one of the charge derivation component 30 and the electromagnetic field shielding component 40 in the laminated component 1000, the amount of charge on the second functional layer 20 can be reduced. When the user touches the second functional layer 20, the risk of electric shock can be avoided or reduced, thereby improving the safety of the laminated component 1000 when in use.

[0139] If the laminate body 100 is provided with the second shielding layer 80, an alternating current is applied to the laminate body 100, generating an electromagnetic field within the laminate body 100. Under the influence of this electromagnetic field, an electric potential is generated on the side where the second shielding layer 80 is located, and charge accumulates. Because the second shielding layer 80 is electrically connected to the charge decoupling element 30, which is in turn grounded, the large amount of charge accumulated on the side where the second shielding layer 80 is located can be conducted away by the charge decoupling element 30, thereby reducing the amount of charge on the side where the second shielding layer 80 is located.

[0140] When a user touches the side of the laminate body 100 where the second shielding layer 80 is located, the user does not experience an electric shock because the amount of residual charge on the side where the second shielding layer 80 is located is lower than a preset value. This improves the safety of the laminate assembly 1000 when used in devices such as automobiles.

[0141] Secondly, the second shielding layer 80 can also shield the mounting area of ​​the laminated assembly 1000 (such as the vehicle body sheet metal 400), thereby enhancing the installation of the laminated assembly 1000 and preventing the vehicle body sheet metal 400 from being directly exposed to the user's view. Furthermore, the second shielding layer 80 can partially block ultraviolet rays, thereby reducing the risk of ultraviolet rays directly reaching the charge derivation element 30 and affecting it.

[0142] Referring to Figure 10 , in some embodiments, the second shielding layer 80 can be an insulating layer, and the charge extraction element 30 can extend through the second shielding layer 80 and electrically connect to the laminate body 100. For example, a second hollow hole can be defined in the second shielding layer 80. The conductive area 81 of the second shielding layer 80 in Figure 10 can be considered the second hollow hole, and the charge extraction element 30 can be positioned within the second hollow hole. When alternating current is applied to the laminate assembly 1000, the charge accumulated on the laminate body 100 can first accumulate near the second hollow hole of the second shielding layer 80. The charge extraction element 30 within the second hollow hole can be considered a charge transfer channel, and the large amount of charge accumulated on the laminate body 100 can be extracted through the charge extraction element 30 within the second hollow hole.

[0143] The above arrangement can determine the material for preparing the second shielding layer 80 according to actual conditions, thereby expanding the range of material selection for the second shielding layer 80 and reducing the difficulty of preparing the second shielding layer 80 .

[0144] In practical applications, the laminated assembly 1000 can be used in a vehicle sunroof structure, that is, in a sunroof glass structure. When the laminated assembly is not equipped with a charge decoupling element, a 36V AC current can be applied to the first functional layer of the laminated assembly. Upon measurement, a voltage of 18.54V is generated on the surface of the second functional layer of the laminated assembly. When the laminated assembly 1000 is equipped with a charge decoupling element 30, a 36V AC current can be applied to the first functional layer 10 of the laminated assembly. Upon measurement, a voltage of 0.019V is generated on the surface of the second functional layer 20 of the laminated assembly 1000.

[0145] It can be seen from this that the large amount of charges accumulated on the second functional layer 20 can be guided to the vehicle body by the charge lead-out element 30 and flow to the ground, while the amount of charge remaining on the second functional layer 20 is small, which is not enough to harm the user's body and avoid safety hazards.

[0146] In some embodiments, as shown in FIG4 , when the charge derivation element 30 is electrically connected to the first functional layer 10, the charge derivation element 30 may include a body (not shown) and a connector structure 32. The body may be disposed on the second functional layer 20. Referring also to FIG7 , the connector structure 32 may include a charge derivation portion 321 and a power supply portion 322. One end of the power supply portion 322 may be electrically connected to the first functional layer 10, and the other end of the power supply portion 322 may be electrically connected to an external power source. One end of the charge derivation portion 321 may be electrically connected to the body, and the other end of the charge derivation portion 321 may be grounded. Alternatively, the other end of the charge derivation portion 321 may be electrically connected to the power supply portion 322 to be grounded through the power supply portion 322.

[0147] In some examples, the charge extraction unit 321 can be electrically connected to the power supply unit 322. When one end of the power supply unit 322 is electrically connected to an external power source, the current applied by the external power source can flow through the power supply unit 322 to the first functional layer 10. The first functional layer 10 is capable of generating an electromagnetic field, and the second functional layer 20 can accumulate charge under the action of the first functional layer 10. Because the main body of the charge extraction unit 321 is disposed on the second functional layer 20, with one end of the charge extraction unit 321 connected to the main body and the other end electrically connected to the power supply unit 322, a large amount of charge on the second functional layer 20 can first flow to the main body, then flow through the main body, sequentially through the charge extraction unit 321 and the power supply unit 322, and finally flow to the ground through the power supply unit 322.

[0148] In other examples, as shown in FIG4 , the charge extraction unit 321 can be electrically connected to the ground terminal of the ECU. When one end of the power supply unit 322 can be electrically connected to an external power source, the current applied by the external power source can flow through the power supply unit 322 to the first functional layer 10. The first functional layer 10 is capable of generating an electromagnetic field, and the second functional layer 20 can accumulate charge under the action of the first functional layer 10. Because the main body of the charge extraction unit 321 is disposed on the second functional layer 20 and the charge extraction unit 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 main body, then flow through the main body, through the charge extraction unit 321 and the ECU, and finally flow to the ground.

[0149] The above-mentioned setting can expand the setting mode of the charge derivation component 30 without affecting the function of the charge derivation component 30, thereby expanding the scope of use of the charge derivation component 30.

[0150] In some embodiments, as shown in FIG5 , the power supply unit 322 includes at least two power supply terminals 3221 . Each of the power supply terminals 3221 can be electrically connected to the first functional layer 10 at one end, and can be electrically connected to an external power source at the other end. A charge derivation unit 321 can be electrically connected to the main body at one end, and can be electrically connected to an external ground at the other end.

[0151] 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 collect charge under the action of the first functional layer 10. Since the main body of the charge extraction unit 321 is set on the second functional layer 20, and the charge extraction unit 321 can be electrically connected to the ground terminal of the ECU, the large amount of charge on the second functional layer 20 can first flow to the main body, and then flow through the main body through the charge extraction unit 321 and the ECU, and finally flow to the ground. The above arrangement simplifies the structure of the charge extraction unit 321, allowing it to be directly electrically connected to the ECU, etc.

[0152] In some embodiments, as shown in FIG6 , the charge derivation portion 321 can be disposed on a side of the body facing away from the second transparent substrate 60. The charge derivation portion 321 can include a first conductive portion 3211 and an insulating portion 3212. One end of the first conductive portion 3211 can be electrically connected to the body, and the other end of the first conductive portion 3211 can be electrically connected to an external grounding member. The insulating portion 3212 can wrap around the exterior of the first conductive portion 3211.

[0153] For example, in the example shown in FIG6 , the first conductive portion 3211 may be a cylindrical structure, with one circumferential side of the cylinder being wrapped with an insulating portion 3212. Another side of the cylinder may be electrically connected to the main body, while the remaining side may be electrically connected to an external grounding element (such as an ECU). This configuration simplifies the structure of the charge derivation portion 321.

[0154] Referring to Figures 5 and 7 , in some embodiments, the power supply unit 322 may include at least two power supply terminals 3221, and the charge extraction unit 321 may include at least one connector 3213. The connector 3213 may be used to electrically connect to an external power source, such as an ECU. The charge extraction unit 321 may electrically connect the connector 3213 to the main body, thereby grounding the main body through the external power source.

[0155] The same end of all power supply terminals 3221 can be electrically connected to the connector 3213, and the same other end can be electrically connected between the opposite ends of the first functional layer 10 in the layer thickness direction and the connector 3213, so that an external power source can apply current to the first functional layer 10.

[0156] As shown in FIG7 , in some examples, a charge derivation member 30 can be disposed on the surface of the second functional layer 20 facing away from the active area 11. When disposing the charge derivation member 30, the body of the charge derivation member 30 can be bonded to the second functional layer 20 using silver glue or the like, and the connector structure 32 can be bent to fit the edge of the second functional layer 20, thereby creating side wiring along the edge of the stacked assembly 1000. This side wiring allows the connector structure 32 to connect the body and the first functional layer 10 without compromising the strength of the stacked assembly 1000.

[0157] Among them, the main arrangement of the joint structure 32 can be that the charge derivation part 321 of the joint structure 32 can be installed on the main body, the joint 3213 of the joint structure 32 can be protruded relative to the charge derivation part 321 so as to be electrically connected to an external power supply, and the two power supply terminals 3221 of the joint structure 32 can be in contact with the two opposite surfaces of the first functional layer 10 in the layer thickness direction.

[0158] 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 is provided with a body, which is electrically connected to the connector 3213 via the charge extraction portion 321, and the connector 3213 can also be grounded to the external power source, most of the charge generated in the second functional layer 20 can be transferred by the connector 3213 and other means, thereby reducing the amount of charge accumulated in the second functional layer 20.

[0159] The above-mentioned setting 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, thereby improving the safety of the stacked component 1000 during use.

[0160] Continuing with FIG7 , in some embodiments, the first functional layer 10 may include an active region 11 and an adhesive region 12. The adhesive region 12 may be disposed around the edge of the active region 11. One end of each of the two power supply terminals 3221 may pass through the adhesive region 12 and be electrically connected to opposite ends of the active region 11 in the thickness direction of the stacked component 1000.

[0161] For example, as shown in FIG7 , the active area 11 can be made of PDLC, and the bonding area 12 can be made of PVB. The bonding area 12 can be arranged around the edge of the active area 11. For example, the orthographic projection of the active area 11 on the first transparent substrate 50 can be rectangular, and the orthographic projection of the bonding area 12 on the first transparent substrate 50 can be annular, with the inner ring of the annular structure in contact with the active area 11.

[0162] Providing adhesive regions 12 at the edges of active region 11 improves the adhesion between the entire first functional layer 10 and the two adjacent film layers across the thickness of the laminated component 1000, reducing the likelihood of cracking between the first functional layer 10 and the two film layers. Furthermore, by allowing the power supply terminals 3221 to pass through the adhesive regions 12 and electrically connect to the active region 11, the adhesive regions 12 also enhance the connection stability between the power supply terminals 3221 and the active region 11, reducing the likelihood of separation between the terminals 3221 and the active region 11.

[0163] In some embodiments, the body can be a metal member, and its resistance can be lower than that of the second functional layer 20. For example, the body can be a conductive copper foil. Silver paste can be applied to the second functional layer 20, with the body positioned in the silver-paste-coated area. Because a conductor with lower resistance has lower impedance, its conductivity is also higher. Therefore, the charge generated by the second functional layer 20 can be rapidly transferred to the charge decoupling element 30.

[0164] Please continue to refer to Figure 7. In some embodiments, a first shielding layer 31 is provided on the surface of the main body away from the second functional layer 20. The first shielding layer 31 can be a film layer prepared by ink printing, or a film layer that can play a shielding role and is insulating. Among them, the first shielding layer 31 is provided with a connecting channel 311. The charge derivation part 321 can be embedded in the connecting channel 311. It can also be understood that the first shielding layer 31 at least avoids the part where the charge derivation part 30 is electrically connected to the main body. That is, the first shielding layer 31 does not completely cover the surface of the main body away from the first functional layer 10. The surface of the main body away from the first functional layer 10 may reserve a part of the area where the first shielding layer 31 is not provided.

[0165] For example, the connecting channel 311 shown in Figure 7 is not coated with ink, and the portion not coated with ink is the avoidance portion 33. Of course, in other examples, the avoidance portion 33 may also be protruding relative to the body, but the avoidance portion 33 is not coated with ink.

[0166] In this way, the charges on the second functional layer 20 can be transferred to the charge extraction portion 321 through the connection channel 311 , thereby accelerating the transfer speed of the charges on the second functional layer 20 .

[0167] In actual applications, for example, when the above-mentioned laminated component 1000 is assembled on a vehicle, because the charge derivation component 30 is installed in the area where the first shielding layer 31 is located, when the charge derivation component 30 is connected to the sheet metal on the vehicle body or the ECU on the vehicle body, the first shielding layer 31 can shield the vehicle body sheet metal to reduce the probability of being exposed to the user, thereby beautifying the visual effect of the laminated component 1000 after installation.

[0168] Secondly, because the connection channel 311 allows the charge extraction portion 321 to pass through, a relief portion 33 is provided at the connection channel 311. This relief portion 33 does not require ink coating. Therefore, compared to coating the entire side of the body with ink, providing the relief portion 33 can reduce the amount of ink used.

[0169] In some examples, the charge lead-out portion 321 may be in contact with the second functional layer 20 .

[0170] As shown in FIG7 , a connection channel 311 can be provided on the body through a hollowing process. One end of the charge derivation portion 321 can pass through the connection channel 311 and be electrically connected to the second functional layer 20, while the other end can be electrically connected to the connector 3213. Because the two ends of the charge derivation portion 321 are directly electrically connected to the second functional layer 20 and the connector 3213, respectively, the charge derivation portion 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.

[0171] In some embodiments, the stacked component 1000 further includes a fourth shielding layer (not shown in the figure), which is arranged on the side of the body away from the second functional layer 20, and the fourth shielding layer at least avoids the part where the charge output element 30 is electrically connected to the body.

[0172] The fourth shielding layer can be a film layer prepared by printing ink, or a film layer that can provide shielding and insulation. The fourth shielding layer defines a channel. The charge extraction unit 321 can be embedded in the channel. Alternatively, it can be understood that the fourth shielding layer at least avoids the portion of the body that is electrically connected to the charge extraction unit 30. In other words, the fourth shielding layer does not completely cover the surface of the body facing away from the second functional layer 20; a portion of the surface of the body facing away from the second functional layer 20 may be left unprotected by the fourth shielding layer.

[0173] When the above-mentioned laminated component 1000 is assembled on a vehicle, since the charge derivation component 30 is installed in the area where the fourth shielding layer is located, when the charge derivation component 30 is connected to the sheet metal on the vehicle body or the ECU on the vehicle body, the fourth shielding layer can shield the vehicle body sheet metal to reduce the probability of being exposed to the user, thereby beautifying the visual effect of the laminated component 1000 after installation.

[0174] In some embodiments, as shown in FIG5 , the connector structure 32 may include a second conductive portion 323 . Referring also to FIG7 , the second conductive portion 323 may be disposed on a side of the body facing away from the second functional layer 20 . The charge extraction portion 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 portion 323 .

[0175] When the connector 3213 is electrically connected to an external power source, current can flow through the connector 3213 to the second conductive portion 323, and from the second conductive portion 323 to the power supply terminal 3221, and then to the first functional layer 10. Charges on the second functional layer 20 can flow from the charge extraction portion 321 to the second conductive portion 323, and then through the second conductive portion 323 to the connector 3213, and finally to the external power source.

[0176] The electrical connection between the power supply terminal 3221 and the connector 3213 and the electrical connection between the charge derivation portion 321 and the connector 3213 are achieved through the second conductive portion 323 , which can simplify the structure of the connector structure 32 .

[0177] It should be noted that the structure of the charge derivation portion 321 can be changed according to actual conditions, as long as the charge derivation portion 321 is used to achieve electrical connection between the second functional layer 20 and the connector 3213 .

[0178] Referring to FIG. 5 and FIG. 7 , in some examples, the charge leading portion 321 may be bent relative to the second conductive portion 323 toward the main body.

[0179] Alternatively, referring to FIG. 7 and FIG. 8 , in other examples, the charge derivation portion 321 may be formed by a conductive adhesive portion disposed on the second conductive portion 323 , and the conductive adhesive portion may be bonded to the body.

[0180] For example, referring to Figure 8 , the second conductive portion 323 may include a housing and a conductor. The conductor may be housed within the housing, and both the charge derivation portion 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 include a first hollow hole, and the charge derivation portion 321 may be formed from a conductive adhesive member that fills the first hollow hole.

[0181] When a large amount of charges accumulates on the second functional layer 20, most of the charges can be transferred to the connector 3213 through the charge extraction portion 321. In this way, the connection stability between the second conductive portion 323 and the body can be improved without affecting the charge transfer efficiency.

[0182] Furthermore, in some embodiments, as shown in FIG9 , when one end of the charge derivation member 30 is electrically connected to at least a portion of the second shielding layer 80, the laminate body 100 can be mounted on a mounting member (e.g., a vehicle body sheet metal member 400) via the charge derivation member 30, and the charge derivation member 30 can be grounded via the mounting member. In other words, the charge derivation member 30 can be a conductive member with mounting functionality, enriching the functionality of the charge derivation member 30 and providing a self-contained mounting function, eliminating the need for additional mounting components to install the laminate assembly 1000.

[0183] Furthermore, in some embodiments, the charge lead-out member 30 may be adhesively connected between the component to be mounted and the laminate body 100 .

[0184] 9 , for example, the charge derivation member 30 may be a conductive member having an adhesive surface, and different adhesive surfaces of the conductive member may be respectively bonded to the vehicle body sheet metal member 400 and the laminated body 100. This simplifies the installation of the charge derivation member 30 and facilitates user operation.

[0185] In some examples, the charge derivation element 30 may be a conductive adhesive. When the laminated assembly 1000 is mounted on the vehicle body sheet metal 400, assembly of the laminated assembly 1000 can be completed quickly. Furthermore, if the laminated assembly 1000 becomes detached from the vehicle body, it can be easily reinstalled. Furthermore, the inexpensive and readily available conductive adhesive further reduces the production cost of the laminated assembly 1000.

[0186] As shown in Figure 10, in some embodiments, the second functional layer 20 is located on the side of the second shielding layer 80 facing away from the charge derivation element 30, and the second functional layer 20 and the second shielding layer 80 are staggered in the layer thickness direction. In other words, the second shielding layer 80 and the second functional layer 20 are arranged in different layers. Furthermore, the second functional layer 20 and the second shielding layer 80 are electrically connected.

[0187] When an alternating current is applied to the laminate body 100 , the laminate body 100 can generate an electromagnetic field. Under the action of the electromagnetic field, the second functional layer 20 can generate an electric potential to accumulate charges.

[0188] When the second shielding layer 80 is conductive, the second functional layer 20 can be electrically connected to the second shielding layer 80, and the second shielding layer 80 is electrically connected to the charge output element 30. When the second shielding layer 80 is insulating, the second functional layer 20 can pass through the second shielding layer 80 and be electrically connected to the charge output element 30.

[0189] When the charge decoupling element 30 is grounded, the charge accumulated on the second functional layer 20 can be conducted away by the charge decoupling element 30, thereby reducing the amount of charge on the second functional layer 20. When a user touches the second functional layer 20, the residual charge on the second functional layer 20 is lower than a preset value, so the user does not experience an electric shock, thereby improving the safety of the stacked assembly 1000.

[0190] Secondly, the second shielding layer 80 can also shield the mounting area of ​​the laminated assembly 1000 (such as the vehicle body sheet metal 400), thereby enhancing the installation of the laminated assembly 1000 and preventing the vehicle body sheet metal 400 from being directly exposed to the user's view. Furthermore, the second shielding layer 80 can partially block ultraviolet rays, thereby reducing the risk of ultraviolet rays directly reaching the charge derivation element 30 and affecting it.

[0191] Referring to Figure 10 , in some embodiments, the laminated assembly 1000 further includes a first edging member 200. The first edging member 200 may be located on one side of the second shielding layer 80 in the layer thickness direction and may be disposed along the periphery of the second shielding layer 80. In other words, if the orthographic projection of the second shielding layer 80 in the layer thickness direction is a rectangle, then the orthographic projection of the first edging member 200 in the layer thickness direction coincides with the outline of the rectangle, i.e., the orthographic projection of the first edging member 200 coincides with the outline of the rectangle.

[0192] Secondly, the first edging member 200 is constructed with a second hollow hole (not shown), within which a charge decoupling element 30 is located. The first edging member 200 is made of, but not limited to, insulating materials such as polyurethane (PU) and thermoplastic vulcanizate (TPV). The first edging member 200 reduces cracks along the edges of the laminated assembly 1000 and enhances its strength.

[0193] When alternating current is applied to the laminate body 100 , a large amount of charges generated on the second functional layer 20 can be gathered near the second hollow hole and conducted away through the charge lead-out member 30 in the first hollow hole.

[0194] In summary, when the laminated component 1000 is provided with a first edging member 200, a second hollow hole can be opened on the first edging member 200, and a charge lead-out member 30 can be filled in the second hollow hole, so that when alternating current is applied to the laminated component 1000, the charge lead-out member 30 can be used to conduct away a large amount of charge accumulated on the second functional layer 20.

[0195] Continuing with Figure 10, in some embodiments, the laminate body 100 includes a second shielding layer 80. In the thickness direction, the second shielding layer 80 may be located between the first edging member 200 and the second functional layer 20. The second shielding layer 80 may optionally include a third hollow hole (not shown) communicating with the second hollow hole.

[0196] In some examples, as shown in FIG11 , when the third hollow hole is not formed in the second shielding layer 80, the entire second shielding layer 80 is conductive, or the contact area between the second shielding layer 80 and the charge decoupling element 30 is conductive. When an alternating current is applied to the stacked assembly 1000, a large amount of charge on the second functional layer 20 can be directly transferred to the charge decoupling element 30 through the second shielding layer 80, and then discharged through the charge decoupling element 30.

[0197] In other examples, as shown in FIG12 , the second shielding layer 80 is provided with a second hollow hole, and the charge derivation element 30 may pass through the first hollow hole and the second hollow hole in sequence and be electrically connected to the second functional layer 20. The second shielding layer 80 may be an insulating layer.

[0198] When alternating current is applied to the stacked component 1000, a large amount of charges on the second functional layer 20 can accumulate near the second hollow hole, and the charge lead-out element 30 in the second hollow hole and the first hollow hole can form a charge transfer channel, and the above charges can be conducted away through the charge lead-out element 30.

[0199] In the above two methods, the second shielding layer 80 can shield the body sheet metal 400 to prevent the body sheet metal 400 from being directly exposed to the user's line of sight, and can also block part of the ultraviolet rays to reduce the probability of ultraviolet rays directly hitting the charge derivation component 30 and affecting the charge derivation component 30.

[0200] In some embodiments, as shown in FIG12 , the laminated assembly 1000 further includes a second edging member 300. The second edging member 300 can be wrapped around the outer wall of the laminated body 100 and connected to the first edging member 200. This arrangement allows the second edging member 300 to provide more effective protection for the laminated assembly 1000, further reducing the likelihood of cracks and water ingress along the edges of the laminated assembly 1000, thereby enhancing the strength of the laminated assembly 1000.

[0201] In some embodiments, the laminate body 100 may include two shielding layers. That is, the laminate body 100 may include not only the second shielding layer 80 but also the third shielding layer 90. The second shielding layer 80 and the third shielding layer 90 are provided in separate layers, and the second shielding layer 80 and the third shielding layer 90 may be provided simultaneously, or only one of them may be provided.

[0202] Referring to FIG. 13 , in some examples, when only the third shielding layer 90 is provided in the laminate body 100, the third shielding layer 90 may be located on the side of the first transparent substrate 50 facing the first functional layer 10, and the third shielding layer 90 may be provided along the periphery of the laminate body 100. It can be understood that if the orthographic projection of the first transparent substrate 50 in the layer thickness direction is a rectangle, then the orthographic projection of the third shielding layer 90 in the layer thickness direction coincides with the outline of the rectangle, that is, the orthographic projection of the third shielding layer 90 coincides with the outline of the rectangle.

[0203] In this way, the third shielding layer 90 can shield the charge derivation component 30 and the vehicle body sheet metal component 400 , etc., so as to beautify the visual effect of the laminated component 1000 after installation.

[0204] In some examples, the third shielding layer 90, along its thickness, covers the charge derivation element 30, and the third shielding layer 90 is an insulating member. This not only reduces the difficulty of obtaining the third shielding layer 90, but also improves the coverage of the charge derivation element 30 and the vehicle body sheet metal component 400.

[0205] In other examples, the third shielding layer 90 can cover the charge derivation element 30 in the thickness direction, but the third shielding layer 90 is a non-insulating member. This can improve the covering effect of the charge derivation element 30 and the body sheet metal part 400.

[0206] In some other examples, the third shielding layer 90 is an insulating member, but the projection of the third shielding layer 90 along the layer thickness direction covers but does not cover the charge derivation member 30. In this way, the difficulty of obtaining the third shielding layer 90 can be reduced.

[0207] The charge lead-out member 30 can be directly bonded to the second functional layer 20. When an alternating current is applied to the laminate body 100, a large amount of charges accumulated on the second functional layer 20 can be directly conducted away by the charge lead-out member 30.

[0208] In other examples, as shown in Figure 14, when the second blocking layer 80 and the third blocking layer 90 are simultaneously provided in the laminate body 100, the second blocking layer 80 may be located on the side of the second functional layer 20 away from the second transparent substrate 60, and the third blocking layer 90 may be located on the side of the first transparent substrate 50 facing the first functional layer 10.

[0209] The second shielding layer 80 can selectively open a second hollow hole, and the third shielding layer 90 can also selectively be set as a conductive layer, a film layer or an insulating layer with a conductive area 81 and an insulating area 82, and the specific situation can be determined according to actual conditions.

[0210] As shown in FIG14 , when the second shielding layer 80 is provided with a second hollow hole, alternating current is applied to the laminate body 100 , and a large amount of charges accumulated on the second functional layer 20 can be conducted away through the charge lead-out element 30 in the second hollow hole.

[0211] As shown in FIG15 , when the second shielding layer 80 does not have the second hollow hole, when alternating current is applied to the laminate body 100 , a large amount of charges accumulated on the second functional layer 20 first pass through the second shielding layer 80 and are then conducted away by the charge lead-out element 30 .

[0212] It can be seen from this that by providing the third shielding layer 90 on the laminated body 100 , the specific structure of the laminated component 1000 can be determined according to actual conditions, thereby expanding the scope of use of the laminated component 1000 .

[0213] Please continue to refer to Figure 15. In some embodiments, the second shielding layer 80 and the charge derivation element 30 can be prepared as one component. For example, a bonding conductive area 81 is set on the side of the second shielding layer 80 facing the vehicle body sheet metal 400. The second shielding layer 80 has both conductive and bonding functions to simplify the structure of the laminated component 1000.

[0214] Among them, the bonding conductive area 81 of the second shielding layer 80 can be made of anisotropic conductive film (ACF in English, the full name is Anisotropic Conductive Film). ACF is a transparent polymer connecting material that has the three major properties of bonding, conductivity, and insulation. Its notable feature is that it conducts in the vertical direction and insulates in the horizontal direction.

[0215] Continuing with FIG. 15 , in some embodiments, the projection of the third shielding layer 90 along the thickness direction can cover the charge derivation element 30. The projection of the second shielding layer 80 along the thickness direction can either cover the charge derivation element 30 or not cover the charge derivation element 30. Because the third shielding layer 90 can shield both the vehicle body sheet metal 400 and the charge derivation element 30, preventing the vehicle body sheet metal 400 from being directly exposed to the user's line of sight, and can also partially block ultraviolet rays to reduce the probability of ultraviolet rays directly striking the charge derivation element 30 and affecting it, the second shielding layer 80 can be less restrictive.

[0216] It can be understood that in the stacked component 1000 with both the second shielding layer 80 and the third shielding layer 90, the projections of the second shielding layer 80 and the third shielding layer 90 in the layer thickness direction may be equal or unequal, as long as one of them can cover the charge output element 30.

[0217] Secondly, the third shielding layer 90 can be made of insulating material according to specific circumstances. Therefore, the provision of the third shielding layer 90 can further enrich the internal structure types of the stacked assembly 1000 and expand the application range of the stacked assembly 1000.

[0218] In some embodiments, as shown in FIG16 , the electromagnetic field shielding element 40 further includes an insulating shielding layer 41. The insulating shielding layer 41 can be located on the side of the second functional layer 20 facing away from the first functional layer 10, and the insulating shielding layer 41 at least avoids the portion where the charge derivation element 30 is electrically connected to the body. In other words, the portion where the charge derivation element 30 is electrically connected to the body does not need to be provided with the insulating shielding layer 41.

[0219] Because the insulating shielding layer 41 provides a barrier to the second functional layer 20, the probability of the second functional layer 20 being directly exposed to air is reduced. When a user touches the second functional layer 20, the insulating shielding layer 41 is present, reducing the probability of leakage of charge accumulated on the second functional layer 20, which could result in an electric shock, thereby improving the reliability of the stacked assembly 1000.

[0220] It is understood that in some embodiments, as shown in FIG17 , only the insulating shielding layer 41 may be provided in the stacked assembly 1000. The decision to provide either or both of the insulating shielding layer 41 and the charge derivation element 30 in the stacked assembly 1000 may be based on practical circumstances.

[0221] As shown in FIG18 , in some embodiments, the electromagnetic field shielding element 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 1000 are electrically connected to an external power source. The voltage direction of the first shielding layer 42 is opposite to that of the first functional layer 10. The voltage direction refers to the direction from a high potential to a low potential.

[0222] For example, the positive electrode of the first shielding layer 42 is electrically connected to the positive electrode of the external power supply, and the negative electrode of the first shielding layer 42 is electrically connected to the negative electrode of the external power supply; while the positive electrode of the first functional layer 10 is electrically connected to the negative electrode of the external power supply, and the negative electrode of the first functional layer 10 is electrically connected to the positive electrode of the external power supply. In this way, 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.

[0223] For example, as shown in FIG18 , both ends of the first shielding layer 42 and the first functional layer 10 in the thickness direction of the stacked assembly 1000 are electrically connected to the same external power source. The first shielding layer 42 can be disposed between the first transparent substrate 50 and the adhesive layer 70. When power is supplied to the first shielding layer 42 and the first functional layer 10 simultaneously, the currents flowing into the first shielding layer 42 and the first functional layer 10 are in opposite directions. Therefore, the electromagnetic field generated by the first shielding layer 42 is in opposite directions to the electromagnetic field generated by the first functional layer 10.

[0224] Since the induced current generated by the second functional layer 20 is smaller under the action 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 .

[0225] It is easy to understand that the first shielding layer 42 can be set on a side close to the second functional layer 20 or on a side away from the second functional layer 20, as long as it can block the second functional layer 20 from generating induced current.

[0226] 19 , in some embodiments, only the first shielding layer 42 may be provided in the stacked assembly 1000. Whether to provide either the first shielding layer 42 or the charge derivation element 30 in the stacked assembly 1000 may depend on actual circumstances.

[0227] In some embodiments, as shown in FIG20 , the electromagnetic field shielding element 40 further includes a second shielding layer 43. The second shielding layer 43 can be arranged around the first functional layer 10, avoiding the portion where the charge derivation element 30 is electrically connected to the first functional layer 10. In other words, the second shielding layer 43 is not provided in the portion where the charge derivation element 30 is electrically connected to the first functional layer 10.

[0228] The above-mentioned second shielding layer 43 can be made of a material that can shield the electric field 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 induction when the user touches the second functional layer 20.

[0229] It is understandable that the configuration of the second shielding layer 43 is not limited to the configuration shown in FIG. 13 , and the second shielding layer 43 may also only cover a partial area of ​​the first functional layer 10 .

[0230] 21 , in some embodiments, only the second shielding layer 43 may be provided in the stacked assembly 1000. Whether to provide either the second shielding layer 43 or the charge derivation element 30 in the stacked assembly 1000 may depend on actual circumstances.

[0231] In addition, some embodiments of the present application further provide a connector structure 32 for a stacked assembly. This connector structure 32 may include a charge extraction portion 321 and a power supply portion 322. One end of the power supply portion 322 may be electrically connected to the first functional layer 10 of the stacked assembly 1000, while the other end of the power supply portion 322 may be electrically connected to an external power source. One end of the charge extraction portion 321 may be electrically connected to the main body of the stacked assembly 1000, while the other end of the charge extraction portion 321 may be grounded or electrically connected to the power supply portion 322 for grounding through the power supply portion 322.

[0232] The above-mentioned setting can expand the setting mode of the charge derivation component 30 without affecting the function of the charge derivation component 30, thereby expanding the scope of use of the charge derivation component 30.

[0233] In some embodiments, as shown in FIG5 , the power supply unit 322 includes at least two power supply terminals 3221. Each of these power supply terminals 3221 has one end that can be electrically connected to the first functional layer 10, and the other end that can be electrically connected to an external power source. One end of the charge extraction unit 321 can be electrically connected to the body of the stacked component 1000, and the other end that can be electrically connected to an external grounding element.

[0234] When one end of the power supply terminal 3221 is electrically connected to an external power source, current applied by the external power source can flow through the power supply terminal 3221 to the first functional layer 10. The first functional layer 10 is capable of generating an electromagnetic field, and the second functional layer 20, under the action of the first functional layer 10, can accumulate charge. Because the main body of the charge extraction unit 321 is disposed on the second functional layer 20 and can be electrically connected to the ground terminal of the ECU, the large amount of charge on the second functional layer 20 can first flow to the main body, then flow through the main body, through the charge extraction unit 321 and the ECU, and finally to the ground.

[0235] The above arrangement simplifies the structure of the charge derivation unit 321, so that it can be directly electrically connected to the ECU, etc.

[0236] Referring to Figures 5 and 7 , in some embodiments, the power supply unit 322 may include at least two power supply terminals 3221, and the charge extraction unit 321 may include at least one connector 3213. The connector 3213 may be used to electrically connect to an external power source, such as an ECU. The charge extraction unit 321 may electrically connect the connector 3213 to the main body, thereby grounding the main body of the stacked assembly 1000 via the external power source.

[0237] One end of the power supply terminal 3221 can be electrically connected to the connector 3213 , and the other end of the power supply terminal 3221 can be electrically connected to opposite ends of the first functional layer 10 in the layer thickness direction, so that an external power source can apply current to the first functional layer 10 .

[0238] With such a configuration, the connector structure 32 can be electrically connected to an external power source to apply current to the first functional layer 10 while also being grounded.

[0239] Furthermore, some embodiments of the present application further provide a vehicle. The vehicle includes a vehicle body and the aforementioned laminated assembly 1000. Laminated assembly 1000 can be mounted on the vehicle body. Because the vehicle includes laminated assembly 1000, the vehicle possesses the functions and benefits of laminated assembly 1000 provided in the aforementioned embodiments, which will not be further elaborated here.

[0240] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0241] The above-described embodiments merely represent several implementation methods of the present application. 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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
