[0001] (Related Citation) This application incorporates by reference in its entirety the Chinese application No. 202310429502.5 (Title: Stacked Component, Connector Structure and Vehicle Used for Stacked Component) filed on April 20, 2023 and the Chinese application No. 202321621479.1 (Title: Stacked Component and Vehicle) filed on June 26, 2023.

[0002] This application relates to the field of stacked components, and particularly to stacked components, a connector structure used for stacked components, and vehicles.

Background Art

[0003] A stacked component can be provided with functions such as lighting, privacy (e.g., electrochromism), video display, and heating by including functional elements that functionalize the stacked component. These functional elements are usually mounted inside the stacked component.

[0004] Currently, it is widely used to realize different functions of a stacked component by applying current to the functional elements. However, when current is applied to the functional elements, a large amount of charge accumulates on the surface of the stacked component. If a user touches the surface of the stacked component, there is a risk of electric shock. Therefore, when using the above-mentioned stacked component, there is a safety risk.

Summary of the Invention

[0005] Based on the above, it is necessary to improve the stacked component to solve the problem that when using a conventional stacked component, its second functional layer has a feeling of electric shock and a safety risk. The stacked component can eliminate the feeling of electric shock of the second functional layer and improve the safety when using the stacked component.

[0006] According to the first aspect, the present application includes a laminated body comprising a first transparent substrate, a second transparent substrate, a first functional layer, a second functional layer, and at least one of a charge derivation member and an electromagnetic field shielding member.

[0007] The first functional layer is provided between the first transparent substrate and the second transparent substrate and is used to electrically connect to an external power supply.

[0008] The second functional layer is provided on the side of the second transparent substrate opposite to the first functional layer.

[0009] The charge derivation member is provided on the side of the second functional layer opposite to the second transparent substrate, one end of the charge derivation member is electrically connected to the first functional layer, and the other end of the charge derivation member is used for grounding.

[0010] The electromagnetic field shielding member is provided between the first functional layer and the second functional layer, or the electromagnetic field shielding member is provided on the side of the second functional layer opposite to the second transparent substrate.

[0011] or,

[0012] The laminated body further includes a second shielding layer, which is provided on the side of the second functional layer opposite to the second transparent substrate, and the second shielding layer is provided along the periphery of the laminated body, one end of the charge derivation member is electrically connected to at least a portion of the second shielding layer, and the other end of the charge derivation member is used for grounding.

[0013] By providing at least one of a charge deducting member and an electromagnetic field shielding member within the laminated component, the amount of charge in the second functional layer can be reduced, allowing users to avoid or reduce the risk of electric shock when touching the second functional layer, thereby improving safety during the use of the laminated component.

[0014] When a second shielding layer is provided in the laminated body, applying AC power to the laminated body generates an electromagnetic field inside the laminated body, creating a potential on the side where the second shielding layer is located and allowing charge to accumulate. Since the second shielding layer and the charge derivation member are electrically connected and the charge derivation member is grounded, the large amount of charge accumulated on the side where the second shielding layer is located can be derived by the charge derivation member, thereby reducing the amount of charge on that side.

[0015] When a user touches the side of the laminated body where the second shielding layer is located, the amount of residual charge on the side where the second shielding layer is located is lower than a predetermined value, so the user does not feel an electric shock. Applying this laminated component to equipment such as automobiles can improve the safety of using the laminated component.

[0016] Next, the second shielding layer can shield the mounting area of ​​the laminated component (e.g., sheet metal parts of the vehicle body), improving the appearance of the laminated component's mounting and preventing the sheet metal parts of the vehicle body from being directly exposed to the user's line of sight. In addition, the second shielding layer can also partially shield ultraviolet rays to reduce the impact of ultraviolet rays directly shining on the charge derivation member.

[0017] In possible embodiments, when the charge derivation member is electrically connected to the first functional layer, the charge derivation member includes a body and a connector structure, the body being installed on the second functional layer.

[0018] The connector structure comprises a power supply unit, one end of which is electrically connected to a first functional layer and the other end of which is electrically connected to an external power supply, and a charge deducting unit, one end of which is electrically connected to the main body and the other end is grounded, or the other end is electrically connected to the power supply unit and grounded via the power supply unit.

[0019] In this way, the arrangement of charge derivation members can be expanded without affecting the operation of the charge derivation members, thereby expanding the range of use of the charge derivation members.

[0020] In one possible embodiment, the power supply unit includes at least two power supply terminals, one end of which is electrically connected to a first functional layer and the other end of which is electrically connected to an external power supply; one end of the charge derivation unit is electrically connected to the main body and the other end of which is electrically connected to an external grounding member.

[0021] This simplifies the structure of the charge derivation section, allowing for direct electrical connection to the ECU and other components.

[0022] In possible embodiments, the charge derivation section is provided on the side of the main body opposite to the second transparent substrate, and the charge derivation section includes a first conductive section and an insulating section, one end of the first conductive section is electrically connected to the main body, the other end of the first conductive section is electrically connected to an external grounding member, and the insulating section covers the outside of the first conductive section.

[0023] This allows for a simplification of the charge derivation section's configuration.

[0024] In one possible embodiment, the power supply unit includes at least two power supply terminals, the charge deducting unit includes at least one connector for electrically connecting to an external power supply, and the charge deducting unit electrically connects the connector and the body so that the body is grounded via the external power supply.

[0025] One end of each power supply terminal is electrically connected to a connector, and the other end of each power supply terminal is electrically connected between the contacts and both ends of the first functional layer in the thickness direction, such that an external power supply applies current to the first functional layer.

[0026] By improving the connector structure that supplies power to the first functional layer, the connector structure can be grounded while supplying power to the first functional layer, reducing the amount of charge accumulated in the second functional layer and improving the safety of the laminated component during use.

[0027] In possible embodiments, a first shielding layer is provided on the surface of the main body opposite to the second functional layer, a connection passage is provided in the first shielding layer, and a charge deducting portion is fitted into the connection passage.

[0028] Thus, since the charge导出member is attached to the region where the first shielding layer is located, when the charge导出member is connected to the body panel of the vehicle body or the ECU in the vehicle body, the first shielding layer can shield the body panel of the vehicle body, reduce the probability of appearing in front of the user, and improve the appearance after the laminated component is attached. The charge in the second functional layer can be transferred to the charge导出portion through the connection passage, thereby increasing the transfer speed of the charge on the second functional layer.

[0029] In a possible embodiment, the charge导出portion is in contact with the second functional layer.

[0030] Since both ends of the charge导出portion are directly electrically connected to the second functional layer and the contact respectively, the charge accumulated in the second functional layer can be quickly and accurately transferred by the charge导出portion, and the speed of transferring the charge is improved.

[0031] In a possible embodiment, the connector structure further includes a second conductive portion provided on the opposite side of the main body with respect to the second functional layer.

[0032] Both between the charge导出portion and the contact, and between the power supply terminal and the contact are electrically connected through the second conductive portion.

[0033] By realizing the electrical connection between both the power supply terminal and the contact and the electrical connection between the charge导出portion and the contact by the second conductive portion, the configuration of the connector structure can be simplified.

[0034] In one possible embodiment, the charge导出portion is provided to bend toward the main body with respect to the second conductive portion, or the charge导出portion is formed by a conductive adhesive portion structure provided on the second conductive portion, and the conductive adhesive portion adheres to the main body.

[0035] When a large amount of charge accumulates in the second functional layer, most of the charge can be transferred to the contacts via the charge derivation section. This improves the connection stability between the second conductive section and the main body without affecting the charge transfer efficiency.

[0036] In possible embodiments, the second conductive part includes a housing and a conductor, the conductor is housed inside the housing, and the charge deducting part and the connector, and the power supply terminal and the connector are both electrically connected via the conductor.

[0037] The housing is provided with a first weight-reducing hole, the charge-deducting section is formed by a conductive adhesive section, and the conductive adhesive section is filled into the first weight-reducing hole.

[0038] This makes it possible to improve the connection stability between the second conductive part and the main body without affecting the charge transfer efficiency.

[0039] In possible embodiments, the body is made of metal, and the resistance of the body is less than the resistance of the second functional layer.

[0040] The lower the electrical resistance of a conductor, the lower its impedance becomes, and therefore the stronger its conductivity. This allows the charge generated in the second functional layer to be quickly transferred to the charge derivation member.

[0041] In one possible embodiment, the first functional layer includes an action region and an adhesive region, the adhesive region being provided around the edge of the action region, and one end of each of two power supply terminals passing through the adhesive region and electrically connected to the action region and both ends on the front and back sides in the thickness direction of the laminated component, respectively.

[0042] By providing an adhesive region at the edge of the working region, the adhesive effect between the entire first functional layer and two adjacent film layers in the thickness direction of the laminated component can be improved, reducing the probability of cracks occurring between the first functional layer and the two film layers. Furthermore, since the power supply terminal is electrically connected by penetrating the adhesive region and the working region, the adhesive region also improves the connection stability between the power supply terminal and the working region, reducing the probability of separation between the power supply terminal and the working region.

[0043] In possible embodiments, the laminated component further includes a fourth shielding layer, the fourth shielding layer being located on the side of the main body opposite to the second functional layer, and the fourth shielding layer avoids at least the portion where the charge derivation portion and the main body are electrically connected.

[0044] When the above-mentioned laminated component is installed in a vehicle, since the charge deducting member is installed in the area where the fourth shielding layer is located, if the charge deducting member is connected to the sheet metal of the vehicle body or the ECU in the vehicle body, the fourth shielding layer can shield the sheet metal of the vehicle body, reducing the probability of it being visible to the user and improving the appearance of the laminated component after installation.

[0045] 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 attached to the mounting target member via the charge derivation member, and the charge derivation member is grounded via the mounting target member.

[0046] In possible embodiments, the charge derivation member is adhesively connected between the member to be attached and the laminated body.

[0047] In this way, the mounting method for the charge derivation member is simplified, making user operation easier.

[0048] In possible embodiments, the charge derivation member is a conductive adhesive member.

[0049] When attaching laminated components to the sheet metal parts of the vehicle body, the assembly of the laminated components can be completed quickly. Furthermore, even if the laminated components detach from the vehicle body, they can be easily reattached, and the production cost of the laminated components can be reduced by using inexpensive and readily available conductive adhesive materials.

[0050] In one possible embodiment, the laminated component further includes a first border member, the first border member located on one side in the thickness direction of the second shielding layer, the first border member having a second weight-reducing hole, and a charge-deducting member provided within the second opening.

[0051] When a first border member is provided in a laminated component, a second weight-reducing hole is provided in the first border member, and a charge-deducting member is filled into the second weight-reducing hole. When AC power is applied to the laminated component, the charge-deducting member can deduct a large amount of charge accumulated in the second functional layer.

[0052] In possible embodiments, the laminated component further includes a second edging member that covers the outer periphery wall of the laminated body and is connected to the first edging member.

[0053] By using the second edging member, the laminated component can be protected more effectively, further reducing the probability of crack formation at the edges of the laminated component and the likelihood of water entering the edges, thereby improving the strength of the laminated component.

[0054] In one possible embodiment, the second functional layer is located on the opposite side of the charge derivation member of the second shielding layer, the second functional layer and the second shielding layer are offset in the thickness direction, and the second functional layer and the second shielding layer are electrically connected.

[0055] After grounding the charge derivation member, the charge accumulated in the second functional layer can be derived by the charge derivation member, thereby reducing the amount of charge in the second functional layer. When a user touches the second functional layer, the amount of charge remaining in the second functional layer is lower than a predetermined value, so the user will not be electrocuted, improving the safety of using the laminated component.

[0056] Next, the second shielding layer can shield the mounting area of ​​the laminated component (for example, the sheet metal member of the vehicle body), improving the appearance of the laminated component's mounting and preventing the sheet metal member of the vehicle body from being directly exposed to the user's line of sight. In addition, the second shielding layer 80 can also affect the charge derivation member by shielding it from ultraviolet rays.

[0057] In possible embodiments, the laminate body further includes a third shielding layer located on the side of the first transparent substrate facing the first functional layer, the third shielding layer being provided along the periphery of the laminate body.

[0058] In this way, the third shielding layer can shield the charge derivation member and the sheet metal members of the vehicle body all at once, improving the appearance after the laminated component is installed.

[0059] In possible embodiments, the third shielding layer has a projection along the thickness direction that covers the charge derivation member, and the third shielding layer is an insulating member.

[0060] Thus, not only is the difficulty of obtaining the third shielding layer reduced, but the shielding effect on charge derivation members and sheet metal members of the vehicle body is also improved.

[0061] In possible embodiments, the third shielding layer has a projection along the thickness direction that covers the charge derivation member.

[0062] This method enhances the concealment effect on charge-deducting members and sheet metal parts of the vehicle body.

[0063] In possible embodiments, the third shielding layer is an insulating material.

[0064] In this way, the difficulty of acquiring the third shielding layer can be reduced.

[0065] In possible embodiments, the electromagnetic field shielding member further includes an insulating shielding layer located on the opposite side of the second functional layer from the first functional layer, and at least avoiding the portion where the charge derivation portion and the main body are electrically connected.

[0066] When a user touches the second functional layer, the presence of a single insulating shield layer reduces the probability of electric shock to the user due to the leakage of charge accumulated in the second functional layer, thereby improving the reliability of the multilayer component.

[0067] In possible embodiments, the electromagnetic field shielding member further includes a first shielding layer provided between a second functional layer and a first functional layer.

[0068] The first shielding layer and the first functional layer are used to electrically connect an external power supply to both ends of the layer thickness direction of the laminated component, and the voltage direction of the first shielding layer is opposite to the voltage direction of the first functional layer.

[0069] Because the electromagnetic field generated by the first shielding layer results in a relatively small induced current generated by the second functional layer, the charge accumulated by the second functional layer is also relatively small, thus reducing the probability of touch induction occurring when a user touches the second functional layer.

[0070] In possible embodiments, the first shield layer and the first functional layer are used to electrically connect to the same external power supply at both ends in the thickness direction of the laminated component.

[0071] When power is supplied to both the first shielding layer and the first functional layer simultaneously, the direction of the current flowing into both layers is opposite. Therefore, the direction of the electromagnetic field generated by the first shielding layer and the direction of the electromagnetic field generated by the first functional layer are opposite. Because the electromagnetic field generated by the first shielding layer induces a relatively small current in the second functional layer, the charge accumulated in the second functional layer is also relatively small, thus reducing the probability of electric shock when a user touches the second functional layer.

[0072] In possible embodiments, the electromagnetic field shielding member further includes a second shielding layer distributed to surround the first functional layer and avoiding portions that electrically connect the charge derivation member and the first functional layer.

[0073] The second shielding layer can reduce the probability of induced currents occurring in the second functional layer, thereby reducing the amount of charge accumulated in the second functional layer and lowering the probability of electric shock when a user touches the second functional layer.

[0074] According to a second aspect, the present invention provides a connector structure for use in a stacked component, the connector structure including the charge derivation section and the power supply section, one end of the power supply section being electrically connected to the first functional layer of the stacked component, the other end of the power supply section being electrically connected to an external power supply, one end of the charge derivation section being electrically connected to the main body of the stacked component, and the other end of the charge derivation section being grounded or electrically connected to the power supply section and grounded via the power supply section.

[0075] In this way, the arrangement of charge derivation members can be expanded without affecting the operation of the charge derivation members, thereby expanding the range of use of the charge derivation members.

[0076] In one possible embodiment, the power supply unit includes at least two power supply terminals, one end of which is electrically connected to a first functional layer and the other end of which is electrically connected to an external power supply; one end of the charge derivation unit is electrically connected to the body of a laminated component and the other end of which is electrically connected to an external grounding member.

[0077] This simplifies the structure of the charge derivation section, allowing for direct electrical connection to the ECU and other components.

[0078] In one possible embodiment, the power supply unit includes at least two power supply terminals, the charge deducting unit includes at least one connector for electrically connecting an external power supply, and the charge deducting unit electrically connects the connector and the body of the laminated component so that the body of the laminated component is grounded via the external power supply.

[0079] One end of the power supply terminal is electrically connected to a connector, and the other end of the power supply terminal is electrically connected to both the front and back ends in the thickness direction of the first functional layer so that an external power supply applies current to the first functional layer.

[0080] In this way, the connector structure can electrically connect to an external power supply, apply current to the first functional layer, and simultaneously be grounded.

[0081] The vehicle comprises a body and the aforementioned laminated components, the laminated components being attached to the body.

[0082] Embodiments of the present application provide a laminated component, a connector structure used in the laminated component, and a vehicle, wherein the laminated component may be provided with at least one of a charge deducting member and an electromagnetic field shielding member, the charge deducting member being provided on the side of the second functional layer opposite to the first functional layer, and the charge deducting member being groundable. The electromagnetic field shielding member may be provided between the first functional layer and the second functional layer, or the electromagnetic field shielding member may be provided on the side of the second functional layer opposite to the first functional layer.

[0083] When applying current to the first functional layer, if a charge deducting member is provided in the laminated component, the charge deducting member is provided on the side of the second functional layer opposite to the first functional layer, one end of the charge deducting member is electrically connected to the first functional layer, and the other end is grounded, so that the charge accumulated in the second functional layer is deducted by the charge deducting member, thereby reducing the amount of charge in the second functional layer. Since the amount of charge remaining in the second functional layer is lower than a preset value, the risk of electric shock is avoided or reduced when a user touches the second functional layer.

[0084] When an electromagnetic field shielding member is provided in a multilayer component, the electromagnetic field shielding member causes a large amount of charge to accumulate in the second functional layer. When a user touches the second functional layer, they do not feel an electric shock, thus improving the safety of using the multilayer component.

[0085] Furthermore, a second shielding layer may be provided in the laminated body. When alternating current power is applied to the laminated body, an electromagnetic field is generated inside the laminated body. Due to the action of the electromagnetic field, a potential is generated on the side where the second shielding layer is located, allowing charge to accumulate. Since the second shielding layer and the charge derivation member are electrically connected and the charge derivation member is grounded, the large amount of charge accumulated on the side where the second shielding layer is located can be derived by the charge derivation member, thereby reducing the amount of charge on that side.

[0086] When a user touches the side of the laminated body where the second shielding layer is located, the amount of residual charge on the side where the second shielding layer is located is lower than a predetermined value, so the user does not feel an electric shock. Applying this laminated component to equipment such as automobiles can improve the safety of using the laminated component.

[0087] The second shielding layer can also shield the mounting area of ​​the laminated component (e.g., sheet metal parts of the vehicle body), improving the appearance of the laminated component and preventing the sheet metal parts of the vehicle body from being directly exposed to the user's line of sight. In addition, the second shielding layer can also partially shield ultraviolet rays to reduce the impact of ultraviolet rays directly hitting the charge derivation member.

Furthermore, the drawings described below represent only a few embodiments of this application, and those skilled in the art can obtain other drawings based on these drawings without expending any creative effort.

When one element is considered to be "connected" to the other element, it may be directly connected to the other element, or an intermediate element may exist simultaneously.

[0095] Referring to Figures 1 and 2, an embodiment of the present invention provides a laminated component 1000. The laminated component 1000 includes a laminated body 100. Both the charge derivation member 30 and the electromagnetic field shielding member 40 may be provided, or only one of them may be provided. The laminated body 100 includes a first transparent substrate 50, a second transparent substrate 60, a first functional layer 10, a second functional layer 20, and at least one of the charge derivation member 30 and the electromagnetic field shielding member 40.

[0096] The first functional layer 10 is provided between the first transparent substrate 50 and the second transparent substrate 60 and is electrically connected to an external power supply. The second functional layer 20 is provided on the side of the second transparent substrate 60 opposite to the first functional layer 10. The charge deducting member 30 is provided on the side of the second functional layer 20 opposite to the second transparent substrate 60, with one end of the charge deducting member 30 electrically connected to the first functional layer 10 and the other end of the charge deducting member 30 being grounded. The electromagnetic field shielding member 40 is provided between the first functional layer 10 and the second functional layer 20, or the electromagnetic field shielding member 40 is provided on the side of the second functional layer 20 opposite to the second transparent substrate 60.

[0097] Alternatively, the laminated body 100 further includes a second shielding layer 80. The second shielding layer 80 is provided on the side of the second functional layer 20 opposite to the second transparent substrate 60, and is provided along the periphery of the laminated body 100, with one end of the charge derivation member 30 electrically connected to at least a portion of the second shielding layer 80, and the other end of the charge derivation member 30 used for grounding.

[0098] The first transparent substrate 50 and the second transparent substrate 60 may both be ordinary glass, and the first transparent substrate 50 and the second transparent substrate 60 may be provided on both sides of the first functional layer 10 along the layer thickness direction of the laminated component 1000, and an adhesive layer 70 may be provided between each layer's transparent substrate and the first functional layer 10 to provide an adhesive effect between the transparent substrate and the first functional layer 10. Here, the adhesive layer 70 can be manufactured using bonding materials such as polyvinyl butyral (PVB), polyurethane, polyurethane (PU), and ethylene-vinyl acetate copolymer (EVA), and the manufacturing material for the first functional layer 10 is not limited to one or more combinations of polymer dispersed liquid crystal (PDLC), guest host effect liquid crystal (GHLC), electrochromic device (ECD), suspended particle device (SPD), LC, light-emitting diode (LED), heat-shielding film, color-changing film, light-guiding film, display film, etc.

[0099] The second transparent substrate 60 is provided parallel to and spaced apart from the first transparent substrate 50, and the first functional layer 10 is provided between the first transparent substrate 50 and the second transparent substrate 60, and may be electrically connected to an external power supply. For example, when the AC power applied to the first functional layer 10 changes, the light transmittance, light absorption rate, and light reflectance of the first functional layer 10 itself change accordingly, which can change the color of the first functional layer 10 or change the temperature of the first functional layer 10.

[0100] The second functional layer 20 may be provided on the side of the second transparent substrate 60 opposite to the first functional layer 10. Here, the second functional layer 20 may be a conductive layer containing a metal, and the conductive layer may be a layer structure having a metallic element, for example, a metal film layer. Of course, the conductive layer is not limited to a film layer made of a single metal such as a copper film, but may be a film layer containing a conductive material, made of a continuously distributed material, or may have a spaced structure such as a mesh.

[0101] For example, insulating layers, radiation-blocking layers, soundproofing layers, and light-regulating layers with conductive properties such as silver plating layers and low-emission (Low-E, Low Emissivity) layers can all be used as second functional layers. Here, the LOW-E layer is made from multiple types of metals and has good heat insulation and light transmission properties.

[0102] The second shielding layer 80 may be an ink layer coated with ink, or a film layer coated with another paint. The layer thickness direction can be considered as the layer thickness direction of the laminated unit 1000. For example, if the orthographic projection of the laminated body 100 in the layer thickness direction is rectangular, the orthographic projection of the second shielding layer 80 in the layer thickness direction may overlap with the outline of the rectangle.

[0103] If a charge deducting member 30 is provided within the laminated component 1000, the charge deducting member 30 may be provided on the side of the second functional layer 20 opposite to the second transparent substrate 60. The charge deducting member 30 may have one end electrically connected to the first functional layer 10 and the other end grounded. For example, one end of the charge deducting member 30 may be electrically connected to the first functional layer 10 and the other end electrically connected to the grounded terminal of an electronic control unit (ECU), or the grounded terminal of the charge deducting member 30 may be directly grounded.

[0104] When an electromagnetic field shielding member 40 is provided within the laminated component 1000, the electromagnetic field shielding member 40 may be provided between the first functional layer 10 and the second functional layer 20, or the electromagnetic field shielding member 40 may be provided on the side of the second functional layer 20 opposite to the second transparent substrate 60.

[0105] The stacked component 1000 will be described below with reference to specific embodiments shown in Figures 1-3, 9, and 10.

[0106] In some examples, only the charge derivation member 30 is provided within the laminated component 1000. As shown in Figure 1, the charge derivation member 30 is provided on the side of the second functional layer 20 opposite to the second transparent substrate 60 and is groundable. When AC power is applied to the first functional layer 10, the first functional layer 10 can generate an electromagnetic field. The second functional layer 20 can generate a potential and store charge due to the electromagnetic field.

[0107] A charge decoupling member 30 is provided on the side of the second functional layer 20 opposite to the second transparent substrate 60, and one end of the charge decoupling member 30 is electrically connected to the first functional layer 10, while the other end is grounded. As a result, the charge accumulated in the second functional layer 20 is decoupled by the charge decoupling member 30, thereby reducing the amount of charge in the second functional layer 20. The amount of charge remaining in the second functional layer 20 is lower than a predetermined value, so that even if a user touches the second functional layer 20, there is no sensation of electric shock, improving the safety of using the laminated component 1000.

[0108] In some other examples, only the electromagnetic field shielding member 40 is provided within the laminated component 1000. As shown in Figure 2, the electromagnetic field shielding member 40 may be provided between the first functional layer 10 and the second functional layer 20. When AC power is applied to the first functional layer 10, the electromagnetic field shielding member 40 reduces the probability of generating induced currents or electromagnetic fields in the second functional layer 20. Due to the action of the electromagnetic field shielding member 40, a large amount of charge is less likely to accumulate in the second functional layer 20, and even if a user touches the second functional layer 20, they will not feel an electric shock.

[0109] In some other examples, a charge deducting member 30 and an electromagnetic field shielding member 40 are provided within the laminated component 1000. As shown in Figure 3, the charge deducting member 30 is provided 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 may be provided between the first functional layer 10 and the second functional layer 20.

[0110] When alternating current is applied to the first functional layer 10, the first functional layer 10 can generate an electromagnetic field. The electromagnetic field shielding member 40 has the function of reducing the probability of induced current and electromagnetic fields being generated in the second functional layer 20, so that a large amount of charge does not easily accumulate in the second functional layer 20 due to the action of the electromagnetic field shielding member 40. In addition, a charge deducting member 30 is provided on the side of the second functional layer 20 opposite to the second transparent substrate 60, and one end of the charge deducting member 30 is electrically connected to the first functional layer 10 and the other end is grounded, so that the charge accumulated in the second functional layer 20 is deducted by the charge deducting member 30, and the amount of charge in the second functional layer 20 can be effectively reduced. By reducing the amount of charge accumulated in the second functional layer 20, the risk of electric shock is avoided or reduced even if a user touches the second functional layer 20.

[0111] In some other examples, as shown in Figure 9, if the entire second shielding layer 80 is a conductive layer, one end of the charge derivation member 30 may be electrically connected to the second shielding layer 80 and the other end may be electrically connected to a grounding member (e.g., a sheet metal member 400 of a vehicle). By applying alternating current to the laminated body 1000, the charge accumulated in the laminated body 100 is first transferred to the second shielding layer 80, then transferred to the charge derivation member 30, and derived through the charge derivation member 30.

[0112] As shown in Figure 10, in some other embodiments, the second shielding layer 80 is conductive only in a portion of its area; in other words, the second shielding layer 80 is divided into two areas, one of which is a conductive area 81 and the other is an insulating area 82. One end of the charge derivation member 30 may be electrically connected to the conductive area 81 of the second shielding layer 80, and the other end of the charge derivation member 30 may be connected to a sheet metal member 400 of the vehicle body.

[0113] When AC power is applied to the laminated body 1000, the large amount of charge accumulated in the laminated body 100 is first accumulated in the conductive region 81 of the second shielding layer 80, then transferred to the charge decomposition member 30 via the conductive region 81, and finally decomposed by the charge decomposition member 30.

[0114] In short, by providing at least one of the charge deducting member 30 and the electromagnetic field shielding member 40 within the laminated component 1000, the amount of charge in the second functional layer 20 can be reduced, allowing the user to avoid or reduce the risk of electric shock when touching the second functional layer 20, thereby improving the safety of using the laminated component 1000.

[0115] When the laminated body 100 is provided with a second shielding layer 80, applying AC power to the laminated body 100 generates an electromagnetic field inside the laminated body 100. The electromagnetic field generates a potential on the side where the second shielding layer 80 is located, allowing charge to accumulate. Since the second shielding layer 80 and the charge derivation member 30 are electrically connected and the charge derivation member 30 is grounded, the large amount of charge accumulated on the side where the second shielding layer 80 is located is derived by the charge derivation member 30, thereby reducing the amount of charge on the side where the second shielding layer 80 is located.

[0116] When a user touches the side of the laminated body 100 where the second shielding layer 80 is located, the user does not feel an electric shock because the amount of residual charge on the side where the second shielding layer 80 is located is lower than a predetermined value. Applying this laminated component 1000 to equipment such as automobiles can enhance the safety of use of the laminated component 1000.

[0117] Next, the second shielding layer 80 can also shield the mounting area of ​​the laminated component 1000 (for example, the sheet metal member 400 of the vehicle body), improving the appearance of the laminated component 1000 and preventing the sheet metal member 400 of the vehicle body from being directly exposed to the user's line of sight. In addition, the second shielding layer 80 can also shield some ultraviolet rays to reduce the amount of ultraviolet rays that directly hit the charge derivation member 30 and affect it.

[0118] Referring to Figure 10, in some embodiments, the second shielding layer 80 may be an insulating layer, and the charge derivation member 30 may penetrate the second shielding layer 80 and be electrically connected to the laminated body 100. For example, a second weight-reducing hole may be provided in the second shielding layer 80, and the conductive region 81 of the second shielding layer 80 in Figure 10 may be considered as the second weight-reducing hole, with the charge derivation member 30 provided inside the second weight-reducing hole. When AC power is applied to the laminated body 1000, the charge accumulated in the laminated body 100 first accumulates in large quantities near the second weight-reducing hole of the second shielding layer 80, and the charge derivation member 30 filled inside the second weight-reducing hole can be considered as a charge transfer passage, and the large amount of charge accumulated in the laminated body 100 can be derived through the charge derivation member 30 inside the second weight-reducing hole.

[0119] The above installation allows for the determination of the material used to manufacture the second shielding layer 80 according to the actual situation, thereby expanding the range of options for the second shielding layer 80 and reducing the difficulty of manufacturing the second shielding layer 80.

[0120] In actual applications, the roof structure of a vehicle can be made from the laminated component 1000, that is, the structure of the roof glass can be made from the laminated component 1000. When a charge deducting member is not provided on the laminated component, when 36V AC power is applied to the first functional layer of the laminated component, it was detected that a voltage of 18.54V is generated on the surface of the second functional layer of the laminated component. When a charge deducting member 30 is provided on the laminated component 1000, when 36V AC power is applied to the first functional layer 10 of the laminated component 1000, it was detected that a voltage of 0.019V is generated on the surface of the second functional layer 20 of the laminated component 1000.

[0121] As a result, the large amount of charge accumulated in the second functional layer 20 can be guided to the vehicle body by the charge derivation member 30 and flow to the ground, reducing the amount of charge remaining in the second functional layer 20, thus avoiding safety risks without harming the user's body.

[0122] In some embodiments, as shown in Figure 4, when the charge deducting member 30 is electrically connected to the first functional layer 10, the charge deducting member 30 may include a main body (not shown) and a connector structure 32, and the main body may be provided on the second functional layer 20. As shown in Figure 7, the connector structure 32 may include a charge deducting section 321 and a power supply section 322, one end of the power supply section 322 may be electrically connected to the first functional layer 10, and the other end of the power supply section 322 may be electrically connected to an external power source. One end of the charge deducting section 321 may be electrically connected to the main body and the other end of the charge deducting section 321 may be grounded, or the other end of the charge deducting section 321 may be electrically connected to the power supply section 322 and grounded via the power supply section 322.

[0123] In some examples, the charge derivation unit 321 may be electrically connected to the power supply unit 322. If one end of the power supply unit 322 is electrically connectable to an external power source, the current applied from the external power source can flow to the first functional layer 10 via the power supply unit 322. The first functional layer 10 can generate an electromagnetic field, and the second functional layer 20 can accumulate charge due to the action of the first functional layer 10. Since the body of the charge derivation unit 321 is provided on the second functional layer 20, one end of the charge derivation unit 321 is connected to the body and the other end is electrically connected to the power supply unit 322. As a result, the large amount of charge in the second functional layer 20 first flows to the body, then flows through the body to the charge derivation unit 321 and the power supply unit 322 in sequence, and finally flows to earth via the power supply unit 322.

[0124] In other examples, as shown in Figure 4, the charge derivation unit 321 may be electrically connected to the ground terminal of the ECU. If one end of the power supply unit 322 is electrically connectable to an external power source, the current applied from the external power source can flow to the first functional layer 10 via the power supply unit 322. The first functional layer 10 can generate an electromagnetic field, and the second functional layer 20 can accumulate charge due to the action of the first functional layer 10. Since the body of the charge derivation unit 321 is provided on the second functional layer 20 and the charge derivation unit 321 is electrically connected to the ground terminal of the ECU, the large amount of charge in the second functional layer 20 first flows to the body, then flows through the body to the charge derivation unit 321 and the ECU, and finally flows to earth.

[0125] In this way, the arrangement of the charge deducting members 30 can be expanded without affecting the operation of the charge deducting members 30, thereby broadening the range of use of the charge deducting members 30.

[0126] In some embodiments, referring to Figure 5, the power supply unit 322 includes at least two power supply terminals 3221, where one end of each power supply terminal 3221 may be electrically connected to the first functional layer 10, and the other end of each power supply terminal 3221 may be electrically connected to an external power source. One end of the charge deducting unit 321 may be electrically connected to the main body, and the other end of the charge deducting unit 321 may be electrically connected to an external grounding member.

[0127] If one end of the power supply terminal 3221 is electrically connectable to an external power source, the current applied from the external power source can flow to the first functional layer 10 via the power supply terminal 3221. The first functional layer 10 can generate an electromagnetic field, and the second functional layer 20 can accumulate charge due to the action of the first functional layer 10. Since the main body of the charge deducting unit 321 is provided on the second functional layer 20, and the charge deducting unit 321 is electrically connected to the ground terminal of the ECU, the large amount of charge in the second functional layer 20 first flows to the main body, then flows through the main body to the charge deducting unit 321 and the ECU, and finally flows to ground. In this way, the configuration of the charge deducting unit 321 can be simplified and it can be directly electrically connected to the ECU, etc.

[0128] In some embodiments, as shown in Figure 6, the charge derivation section 321 may be provided on the side of the main body opposite to the second transparent substrate 60. The charge derivation section 321 includes a first conductive section 3211 and an insulating section 3212, one end of the first conductive section 3211 may be electrically connected to the main body, and the other end of the first conductive section 3211 may be electrically connected to an external grounding member. The insulating section 3212 may cover the outside of the first conductive section 3211.

[0129] For example, in the example shown in Figure 6, the structure of the first conductive part 3211 may be cylindrical, with one side of the cylindrical body along its circumferential direction enclosing one insulating part 3212, the other side of the cylindrical body being electrically connected to the main body, and the remaining side being electrically connected to an external grounding member (e.g., an ECU). This simplifies the configuration of the charge derivation part 321.

[0130] 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 deducting unit 321 may include at least one contact 3213. Here, the contact 3213 may be used to electrically connect an external power supply, for example, the contact 3213 may be electrically connected to an ECU. The charge deducting unit 321 can be electrically connected to the connector 3213 and the main body so that the main body is grounded via the external power supply.

[0131] All identical ends of the power supply terminals 3221 may be electrically connected to the connector 3213, and the other end may be electrically connected to the contacts 3213, respectively, between the front and back ends of the first functional layer 10 in the thickness direction and the contacts 3213, so that an external power supply can apply current to the first functional layer 10.

[0132] As shown in Figure 7, in some examples, the charge deducting member 30 may be provided on the surface of the second functional layer 20 opposite to the working area 11. When installing the charge deducting member 30, the body of the charge deducting member 30 can be bonded to the second functional layer 20 with 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 wiring can be performed along the edge of the laminated component 1000. Side wiring allows the body and the first functional layer 10 to be connected by the connector structure 32 without affecting the strength of the laminated component 1000 itself.

[0133] Here, the main arrangement of the connector structure 32 is such that the charge deducting portion 321 of the connector structure 32 is attached to the main body, and the connector 3213 of the connector structure 32 is provided protruding from the charge deducting portion 321 so as to be electrically connected to an external power supply, and the two power supply terminals 3221 of the connector structure 32 may be in contact with the front and back surfaces of the first functional layer 10 in the layer thickness direction.

[0134] When the connector 3213 of the connector structure 32 is electrically connected to an external power source such as an ECU, power is supplied from the external power source to the first functional layer 10 via the power supply terminal 3221. The second functional layer 20 can also generate electric charge through the action of the first functional layer 10, but the second functional layer 20 is provided with a main body, and since the main body is electrically connected to the charge derivation section 321 and the connector 3213, the connector 3213 can also be grounded to the external power source. As a result, most of the charge generated in the second functional layer 20 can be transferred by the contact 3213, etc., and the amount of charge accumulated in the second functional layer 20 can be reduced.

[0135] According to the above installation, by improving the connector structure 32 that supplies power to the first functional layer 10, the connector structure 32 can be grounded while supplying power to the first functional layer 10, thereby reducing the amount of charge accumulated in the second functional layer 20 and improving the safety of the laminated component 1000 when in use.

[0136] Continuing to refer to Figure 7, in some embodiments, the first functional layer 10 may include an action area 11 and an adhesive area 12. The adhesive area 12 may be provided around the periphery of the action 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 the action area 11 and both ends of the front and back surfaces in the thickness direction of the laminated component 1000, respectively.

[0137] For example, as shown in Figure 7, the working region 11 can be manufactured using PDLC and the adhesive region 12 can be manufactured using PVB. The adhesive region 12 may be provided along the periphery of the working region 11. For example, the orthographic projection of the working region 11 on the first transparent substrate 50 may be rectangular, and the orthographic projection of the adhesive region 12 on the first transparent substrate 50 may be annular, and the inner ring of the annular structure may be in contact with the working region 11.

[0138] By providing an adhesive region 12 at the periphery of the working region 11, the adhesive effect between the entire first functional layer 10 and two adjacent film layers in the layer thickness direction of the laminated component 1000 can be improved, and the probability of cracks occurring between the first functional layer 10 and the two film layers can be reduced. Furthermore, since the power supply terminal 3221 is electrically connected through the adhesive region 12 and the working region 11, the adhesive region 12 also improves the connection stability between the power supply terminal 3221 and the working region 11, effectively reducing separation between the power supply terminal 3221 and the working region 11.

[0139] In some embodiments, the main body may be a metal component, and its resistance may be lower than that of the second functional layer 20. For example, the main body may be conductive copper foil. Silver paste can be applied to the second functional layer 20, and the main body can be placed in the silver paste-coated area. The lower the electrical resistance of the conductor, the lower its impedance becomes, and therefore the stronger its conductivity. Consequently, the charge generated in the second functional layer 20 can be quickly transferred to the charge derivation member 30.

[0140] Continuing to refer to Figure 7, in some embodiments, a first shielding layer 31 is provided on the surface of the main body opposite to the second functional layer 20. The first shielding layer 31 may be a film layer produced by ink printing, or it may be a film layer that has a shielding effect and is insulating. A connection passage 311 is provided in the first shielding layer 31. The charge deducting portion 321 may be fitted into the connection passage 311. The first shielding layer 31 may avoid at least the portion where the charge deducting portion 321 and the main body are electrically connected. That is, the first shielding layer 31 does not completely cover the surface of the main body opposite to the second functional layer 20, and the first shielding layer 31 may not be provided in some areas of the surface of the main body opposite to the second functional layer 20.

[0141] For example, the connecting passage 311 shown in Figure 7 is not coated with ink, and the area where ink is not applied is the avoidance section 33. Of course, in other examples, the avoidance section 33 may be a protrusion relative to the main body, but the avoidance section 33 is not coated with ink.

[0142] This allows the charge of the second functional layer 20 to be transferred to the charge derivation section 321 via the connecting passage 311, thereby improving the charge transfer rate of the second functional layer 20.

[0143] In actual applications, for example, when the laminated component 1000 is attached to a vehicle, since the charge deducting member 30 is attached to the area where the first shielding layer 31 is located, if the charge deducting member 30 is connected to the sheet metal of the vehicle body or to an ECU in the vehicle body, the first shielding layer 31 can shield the sheet metal of the vehicle body, reducing the probability of it being visible to the user and improving the appearance of the laminated component 1000 after installation.

[0144] Next, since the connection passage 311 can pass through the charge derivation section 321, a bypass section 33 is provided in the connection passage 311 where ink is not applied. Therefore, compared to applying ink to the entire side surface of the main body, the amount of ink used can be reduced by providing the bypass section 33.

[0145] In some examples, the charge derivation unit 321 may be in contact with the second functional layer 20.

[0146] As shown in Figure 7, the main body is provided with a connection passage 311 by a material removal process, and one end of the charge deducting section 321 may be electrically connected to the second functional layer 20 by drilling through the connection passage 311, while the other end may be electrically connected to the connector 3213. Since both ends of the charge deducting section 321 are directly electrically connected to the second functional layer 20 and the contact 3213, the charge accumulated in the second functional layer 20 can be transferred quickly and accurately by the charge deducting section 321, improving the rate of charge transfer.

[0147] In some embodiments, the laminated component 1000 further includes a fourth shielding layer (not shown) provided on the side of the main body opposite to the second functional layer 20, and the fourth shielding layer avoids at least the portion where the charge derivation member 30 and the main body are electrically connected.

[0148] The fourth shielding layer may be a film layer produced by ink printing, or a film layer that provides both shielding and insulation. A passage is provided in the fourth shielding layer. The charge deducting portion 321 may be fitted into the passage. It should be understood that the fourth shielding layer avoids at least the portion where the charge deducting member 30 and the main body are electrically connected. That is, the fourth shielding layer does not completely cover the surface of the main body opposite to the second functional layer 20, and the surface of the main body opposite to the second functional layer 20 may not have the fourth shielding layer in some areas.

[0149] When the above-mentioned laminated component 1000 is installed in a vehicle, since the charge deducting member 30 is installed in the area where the fourth shielding layer is located, if the charge deducting member 30 is connected to the sheet metal of the vehicle body or to an ECU in the vehicle body, the fourth shielding layer can shield the sheet metal of the vehicle body, reducing the probability of it being visible to the user and improving the appearance of the laminated component 1000 after installation.

[0150] In some embodiments, as shown in Figure 5, the connector structure 32 may include a second conductive portion 323. Referring to Figure 7, the second conductive portion 323 may be provided on the side of the main body opposite to the second functional layer 20. The charge deducting portion 321 and the contact 3213, and the power supply terminal 3221 and the contact 3213 can both be electrically connected via the second conductive portion 323.

[0151] When contact 3213 is electrically connected to an external power supply, current flows through contact 3213 to the second conductive part 323, from the second conductive part 323 to the power supply terminal 3221, and then to the first functional layer 10. Charge in the second functional layer 20 flows from the charge derivation part 321 to the second conductive part 323, then through the second conductive part 323 to contact 3213, and finally to the external power supply.

[0152] The second conductive part 323 enables electrical connections between the power supply terminal 3221 and the contact 3213, and between the charge deducting part 321 and the contact 3213, thereby simplifying the configuration of the connector structure 32.

[0153] The configuration of the charge derivation unit 321 can be changed according to the actual situation, as long as the electrical connection between the second functional layer 20 and the contact 3213 is achieved by the charge derivation unit 321.

[0154] Referring to Figures 5 and 7, in some examples, the charge derivation portion 321 may be bent toward the main body relative to the second conductive portion 323.

[0155] Alternatively, referring to Figures 7 and 8, in several other examples, the charge derivation section 321 is composed of a conductive adhesive section provided on the second conductive section 323, and the conductive adhesive section is bondable to the main body.

[0156] Illustratively, continuing to refer to Figure 8, the second conductive portion 323 may include a housing and a conductor. The conductor may be housed inside the housing, and the charge deducting portion 321 and the contact 3213, and the power supply terminal 3221 and the contact 3213 may both be electrically connected via the conductor. Here, the housing is provided with a first weight-reducing hole, the charge deducting portion 321 is formed by a conductive adhesive portion, and the conductive adhesive portion is filled into the first weight-reducing hole.

[0157] When a large amount of charge accumulates in the second functional layer 20, most of the charge is transferred to the contact 3213 via the charge derivation section 321. This improves the stability of the connection between the second conductive section 323 and the main body without affecting the charge transfer efficiency.

[0158] Furthermore, in some embodiments, as shown in Figure 9, if one end of the charge derivation member 30 is electrically connected to at least a part of the second shielding layer 80, the laminated body 100 may be attached to the mounting target member (for example, a sheet metal member 400 of the vehicle body) via the charge derivation member 30, and the charge derivation member 30 may be grounded via the mounting target member. In other words, the charge derivation member 30 may be a conductive member having a mounting function, enriching the functionality of the charge derivation member 30 to include a mounting function, eliminating the need to provide additional mounting members to attach it to the laminated component 1000.

[0159] Furthermore, in some embodiments, the charge derivation member 30 may be adhesively connected between the member to be attached and the laminated body 100.

[0160] Continuing to refer to Figure 9, the charge derivation member 30 may, as an example, be a conductive member having an adhesive surface, and the different adhesive surfaces of the conductive member may be bonded to the sheet metal member 400 of the vehicle body and the laminated body 100, respectively. In this way, the mounting method of the charge derivation member 30 is simplified and user operation is made easier.

[0161] In some examples, the charge derivation member 30 may be a conductive adhesive member. When attaching the laminated component 1000 to the sheet metal member 400 of the vehicle body, the assembly of the laminated component 1000 can be completed quickly. Furthermore, even if the laminated component 1000 falls off the vehicle body, it is easy to reattach the laminated component 1000, and the production cost of the laminated component 1000 can be reduced due to the low cost and availability of the conductive adhesive member.

[0162] As shown in Figure 10, in some embodiments, the second functional layer 20 is located on the opposite side of the second shielding layer 80 from the charge derivation member 30, and the second functional layer 20 and the second shielding layer 80 are offset in the thickness direction. In other words, the second shielding layer 80 and the second functional layer 20 are provided in different layers. Here, the second functional layer 20 and the second shielding layer 80 are electrically connected.

[0163] When alternating current power is applied to the laminated body 100, the laminated body 100 can generate an electromagnetic field. The second functional layer 20 can generate an electric potential and store charge due to the electromagnetic field.

[0164] If the second shielding layer 80 is conductive, the second functional layer 20 is electrically connected to the second shielding layer 80, and the second shielding layer 80 is electrically connected to the charge derivation member 30. If the second shielding layer 80 is insulating, the second functional layer 20 may penetrate the second shielding layer 80 and be electrically connected to the charge derivation member 30.

[0165] After the charge derivation member 30 is grounded, the charge accumulated in the second functional layer 20 is derived by the charge derivation member 30, thereby reducing the amount of charge in the second functional layer 20. When a user touches the second functional layer 20, the amount of charge remaining in the second functional layer 20 is lower than a predetermined value, so the user does not feel an electric shock, improving the safety of using the laminated component 1000.

[0166] Next, the second shielding layer 80 can also shield the mounting area of ​​the laminated component 1000 (for example, the sheet metal member 400 of the vehicle body), improving the appearance of the laminated component 1000 and preventing the sheet metal member 400 of the vehicle body from being directly exposed to the user's line of sight. In addition, the second shielding layer 80 can also partially shield ultraviolet rays to reduce the amount of ultraviolet rays that directly hit the charge derivation member 30 and affect it.

[0167] Referring to Figure 10, in some embodiments, the laminated component 1000 further includes a first border member 200, which is located on one side of the second shielding layer 80 in the thickness direction and may be positioned along the periphery of the second shielding layer 80. In other words, if the orthographic projection of the second shielding layer 80 in the thickness direction is rectangular, the orthographic projection of the first border member 200 in the thickness direction coincides with the contour of the rectangle, i.e., the orthographic projection of the first border member 200 coincides with the contour of the rectangle.

[0168] Next, a second weight-reducing hole (not shown) is formed in the first edging member 200, and a charge-deducting member 30 is provided within the second weight-reducing hole. The first edging member 200 is made using, but is not limited to, insulating materials such as polyurethane (PU) or thermoplastic vulcanized rubber (TPV). By installing the first edging member 200, the laminated component 1000 can prevent cracks from occurring in its edging and enhance its own strength.

[0169] When AC power is applied to the laminated body 100, the large amount of charge generated in the second functional layer 20 converges near the second hollow hole and is released through the charge release member 30 in the first hollow hole.

[0170] In summary, when a first border member 200 is provided on the laminated component 1000, a second weight-reducing hole is provided in the first border member 200, and a charge-deducting member 30 is filled into the second weight-reducing hole. When AC power is applied to the laminated component 1000, the charge-deducting member 30 can deduct a large amount of charge accumulated in the second functional layer 20.

[0171] Referring to 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 be provided with a third weight-reducing hole (not shown) that communicates with the second weight-reducing hole.

[0172] In some examples, as shown in Figure 11, if the second shielding layer 80 does not have a third weight-reducing hole, the entire second shielding layer 80 is conductive, or the contact area between the second shielding layer 80 and the charge derivation member 30 is conductive. When AC power is applied to the laminated component 1000, a large amount of charge in the second functional layer 20 can be directly transferred to the charge derivation member 30 via the second shielding layer 80 and derived through the charge derivation member 30.

[0173] In some other examples, as shown in Figure 12, the second shielding layer 80 is provided with a second weight-reducing hole, and the charge derivation member 30 can be electrically connected to the second functional layer 20 by sequentially drilling the first and second weight-reducing holes. The second shielding layer 80 may also be an insulating layer.

[0174] When AC power is applied to the laminated component 1000, the charge in the second functional layer 20 accumulates near the second hollow hole, and the charge derivation member 30 in the second hollow hole and the first hollow hole can form a charge transfer passage, and the charge is derived through the charge derivation member 30.

[0175] In both of the above two methods, the second shielding layer 80 can shield the sheet metal member 400 of the vehicle body, preventing the sheet metal member 400 from being directly exposed to the user's line of sight, and reducing the probability of ultraviolet rays directly shining on the charge derivation member 30 and affecting it.

[0176] In some embodiments, as shown in Figure 12, the laminated component 1000 further includes a second edging member 300. The second edging member may cover the outer periphery wall of the laminated body 100 and be connected to the first edging member 200. In this way, the laminated component 1000 can be more effectively protected by the second edging member 300, further reducing the probability of cracks occurring at the edges of the laminated component 1000 and water easily entering the edges, thereby strengthening the laminated component 1000.

[0177] In some embodiments, the laminated body 100 may include two shielding layers. That is, the laminated body 100 may include not only a second shielding layer 80 but also a third shielding layer 90. The second shielding layer 80 and the third shielding layer 90 may be provided as different layers, and may be provided on both the second shielding layer 80 and the third shielding layer 90, or only one of them may be provided.

[0178] Referring to Figure 13, in some examples, when only the third shielding layer 90 is provided on the laminate body 100, the third shielding layer 90 is located on the side of the first transparent substrate 50 facing the first functional layer 10, and the third shielding layer 90 may be installed along the periphery of the laminate body 100. If the orthographic projection of the first transparent substrate 50 in the thickness direction is rectangular, it can be understood that the orthographic projection of the third shielding layer 90 in the 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.

[0179] In this way, the third shielding layer 90 can shield the charge derivation member 30 and the sheet metal member 400 of the vehicle body all at once, improving the appearance of the laminated component 1000 after installation.

[0180] In some examples, the third shielding layer 90 has a projection in the thickness direction that covers the charge derivation member 30, and the third shielding layer 90 is an insulating material. In this way, not only is the difficulty of obtaining the third shielding layer 90 reduced, but the concealment effect on the charge derivation member 30 and the sheet metal member 400 of the vehicle body is also improved.

[0181] In some other examples, the third shielding layer 90 can cover the charge derivation member 30, but the third shielding layer 90 is a non-insulating material. This enhances the concealment effect on the charge derivation member 30 and the sheet metal members 400 of the vehicle body.

[0182] Furthermore, in some examples, the third shielding layer 90 is an insulating material, but the projection of the third shielding layer 90 in the thickness direction does not cover the charge derivation member 30. This reduces the difficulty of obtaining the third shielding layer 90.

[0183] The charge derivation member 30 may be directly bonded to the second functional layer 20. When AC power is applied to the laminated body 100, the large amount of charge accumulated in the second functional layer 20 is directly guided to the charge derivation member 30.

[0184] In another example, as shown in Figure 14, when both the second shielding layer 80 and the third shielding layer 90 are installed on the laminated body 100, the second shielding layer 80 may be located on the side of the second functional layer 20 opposite to the second transparent substrate 60, and the third shielding layer 90 may be located on the side of the first transparent substrate 50 facing the first functional layer 10.

[0185] The second shielding layer 80 can be selectively provided with second weight-reducing holes, and the third shielding layer 90 can similarly be selectively provided as a conductive layer, and simultaneously provide a film layer or insulating layer for the conductive region 81 and the insulating region 82, and the specific circumstances can be determined according to the actual circumstances.

[0186] As shown in Figure 14, when the second shielding layer 80 is provided with a second weight-reducing hole, AC power is applied to the laminated body 100, and the large amount of charge accumulated in the second functional layer 20 is released by the charge release member 30 in the second weight-reducing hole.

[0187] As shown in Figure 15, if the second shielding layer 80 does not have a second weight-reducing hole, when AC power is applied to the laminated body 100, the large amount of charge accumulated in the second functional layer 20 passes through the second shielding layer 80 and is then released by the charge release member 30.

[0188] As a result, by providing a third shielding layer 90 on the laminated body 100, the specific structure of the laminated component 1000 can be determined according to the actual situation, and the range of use of the laminated component 1000 can be expanded.

[0189] Continuing to refer to Figure 15, in some embodiments, both the second shielding layer 80 and the charge derivation member 30 may be manufactured as a single component. For example, an adhesive conductive region 81 is provided on the side of the second shielding layer 80 facing the sheet metal member 400 of the vehicle body, and the second shielding layer 80 serves both the conductive and adhesive roles, simplifying the structure of the laminated component 1000.

[0190] Here, the adhesive conductive region 81 of the second shielding layer 80 can be made of an anisotropic conductive adhesive film (hereinafter abbreviated as ACF). ACF is a transparent polymer connecting material that simultaneously possesses three major properties: adhesion, conductivity, and insulation. Its most notable feature is that it conducts electricity along the vertical direction and insulates along the horizontal direction.

[0191] Continuing to refer to Figure 15, in some embodiments, the projection of the third shielding layer 90 in the thickness direction can shield the charge derivation member 30. The projection of the second shielding layer 80 in the thickness direction may or may not shield the charge derivation member 30. Since the third shielding layer 90 can shield both the sheet metal member 400 of the vehicle body and the charge derivation member 30 together, it can prevent the sheet metal member 400 of the vehicle body from being directly exposed to the user's line of sight, shield some of the ultraviolet rays, and reduce the probability that ultraviolet rays will directly hit the charge derivation member 30 and affect it. Therefore, the second shielding layer 80 is not particularly limited.

[0192] If the laminated component 1000 is provided with both a second shielding layer 80 and a third shielding layer 90, the projections of the second shielding layer 80 and the third shielding layer 90 in the thickness direction may or may not be equal, as long as one of them can cover the charge derivation member 30.

[0193] Next, the third shielding layer 90 can be manufactured using insulating material or not, depending on the specific circumstances. Therefore, by providing the third shielding layer 90, the types of internal structures of the laminated component 1000 can be further enriched, and the range of applications for the laminated component 1000 can be expanded.

[0194] In some embodiments, as shown in Figure 16, the electromagnetic field shielding member 40 further includes an insulating shielding layer 41. The insulating shielding layer 41 may be located on the opposite side of the second functional layer 20 from the first functional layer 10, and the insulating shielding layer 41 may avoid at least the portion where the charge derivation member 30 and the main body are electrically connected. In other words, the insulating shielding layer 41 may not be provided in the portion where the charge derivation member 30 and the main body are electrically connected.

[0195] The insulating shield layer 41 acts as a barrier to the second functional layer 20, thereby reducing the probability that the second functional layer 20 is directly exposed to the air. When a user touches the second functional layer 20, the presence of the insulating shield layer 41 reduces the probability of the charge accumulated in the second functional layer 20 leaking to the outside and causing electric shock to the user, thereby improving the reliability of the laminated component 1000.

[0196] In some embodiments, as shown in Figure 17, the laminated component 1000 may be provided only with an insulating shield layer 41. Whether to install either the insulating shield layer 41 or the charge derivation member 30, or both, on the laminated component 1000 can be determined on a case-by-case basis.

[0197] As shown in Figure 18, in some embodiments, the electromagnetic field shielding member 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 provided between the second functional layer 20 and the first functional layer 10. The first shielding layer 42 and the first functional layer 10 are used to electrically connect an external power supply to both ends of the layer thickness direction of the laminated component 1000, 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 is the direction from high potential to low potential.

[0198] For example, the positive electrode of the first shielding layer 42 is electrically connected to the positive electrode of the external power supply, the negative electrode of the first shielding layer 42 is electrically connected to the negative electrode of the external power supply, 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.

[0199] Exemplary, as shown in Figure 18, the first shielding layer 42 and the first functional layer 10 are used to electrically connect both ends of the laminated component 1000 in the thickness direction to the same external power supply. The first shielding layer 42 may be provided 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 direction of the current flowing into both the first shielding layer 42 and the first functional layer 10 is opposite, so the direction of the electromagnetic field generated by the first shielding layer 42 and the direction of the electromagnetic field generated by the first functional layer 10 are opposite.

[0200] Because the electromagnetic field generated by the first shielding layer 42 results in a small induced current in the second functional layer 20, the amount of charge accumulated in the second functional layer 20 is also reduced, thereby lowering the probability of electric shock when a user touches the second functional layer 20.

[0201] The first shielding layer 42 may be provided on the side closer to the second functional layer 20, or on the side opposite to the second functional layer 20, as long as it can play a role in generating an induced current in the second functional layer 20.

[0202] As shown in Figure 19, in some embodiments, the laminated component 1000 may be provided with only the first shield layer 42. The first shield layer 42 and / or the charge derivation member 30 may be provided in the laminated package 1000 depending on the actual situation.

[0203] In some embodiments, as shown in Figure 20, the electromagnetic field shielding member 40 further includes a second shielding layer 43. The second shielding layer 43 is distributed around the first functional layer 10, and the second shielding layer 43 avoids the electrical connection portion between the charge derivation member 30 and the first functional layer 10. In other words, the second shielding layer 43 is not provided in the portion where the charge derivation member 30 and the first functional layer 10 are electrically connected.

[0204] The second shielding layer 43 can be manufactured using a material that can shield electric fields, thereby reducing the probability of induced currents occurring in the second functional layer 20, and consequently reducing the amount of charge accumulated in the second functional layer 20, thereby reducing the probability of electric shock when a user touches the second functional layer 20.

[0205] As will be understood by those skilled in the art, the installation method of the second shield layer 43 is not limited to the method shown in Figure 13, and the second shield layer 43 may cover only a portion of the first functional layer 10.

[0206] As shown in Figure 21, in some embodiments, the laminated component 1000 may be provided only with the second shielding layer 43. One or all of the second shielding layer 43 and the charge derivation member 30 can be provided in the laminated package 1000 depending on the actual situation.

[0207] Furthermore, some embodiments of the present application provide a connector structure 32 for use in a laminated component. This connector structure 32 may include a charge deducting section 321 and a power supply section 322. One end of the power supply section 322 is electrically connected to the first functional layer 10 of the laminated component 1000, and the other end of the power supply section 322 can be used to electrically connect to an external power source. One end of the charge deducting section 321 is used to electrically connect to the body of the laminated component 1000, and the other end of the charge deducting section 321 may be grounded or electrically connected to the power supply section 322 so as to be grounded via the power supply section 322.

[0208] In this way, the arrangement of the charge deducting members 30 can be expanded without affecting the operation of the charge deducting members 30, thereby broadening the range of use of the charge deducting members 30.

[0209] In some embodiments, referring to Figure 5, the power supply unit 322 includes at least two power supply terminals 3221, where one end of each power supply terminal 3221 is used for electrical connection to the first functional layer 10, and the other end of each power supply terminal 3221 can be used for electrical connection to an external power source. One end of the charge deducting unit 321 is electrically connected to the body of the laminated component 1000, and the other end of the charge deducting unit 321 can be electrically connected to an external grounding member.

[0210] If one end of the power supply terminal 3221 is electrically connectable to an external power source, the current applied from the external power source can flow to the first functional layer 10 via the power supply terminal 3221. The first functional layer 10 can generate an electromagnetic field, and the second functional layer 20 can accumulate charge due to the action of the first functional layer 10. Since the main body of the charge deducting unit 321 is provided on the second functional layer 20, and the charge deducting unit 321 is electrically connected to the ground terminal of the ECU, the large amount of charge in the second functional layer 20 first flows to the main body, then flows through the main body to the charge deducting unit 321 and the ECU, and finally flows to the ground.

[0211] This simplifies the configuration of the charge derivation unit 321, allowing for direct electrical connection to the ECU and other components.

[0212] 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 deducting unit 321 may include at least one contact 3213. Here, the contact 3213 may be used to electrically connect an external power supply, for example, the contact 3213 may be electrically connected to an ECU. The charge deducting unit 321 can electrically connect the connector 3213 and the body of the stacked component 1000 so that the body of the stacked component 1000 is grounded via the external power supply.

[0213] One end of the power supply terminal 3221 may be electrically connected to the connector 3213, and the other end of the power supply terminal 3221 may be electrically connected to both ends of the front and back surfaces in the thickness direction of the first functional layer 10, respectively, so that an external power supply can apply current to the first functional layer 10.

[0214] In this way, the connector structure 32 can be electrically connected to an external power supply to apply current to the first functional layer 10 and simultaneously grounded.

[0215] Furthermore, some embodiments of the present application further provide a vehicle comprising a vehicle body and the laminated component 1000, where the laminated component 1000 may be attached to the vehicle body. Since the vehicle includes the laminated component 1000, the vehicle has the functions and beneficial effects of the laminated component 1000 according to the above embodiment, which are omitted from this description.

[0216] Any combination of the technical features of the above embodiments is possible, and for the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as these combinations of technical features are inconsistent, they should be understood to fall within the scope described herein.

[0217] The embodiments described above are merely examples of some embodiments of this application, and although their description has been detailed, it should not be construed as limiting the scope of the claims. To those skilled in the art, several modifications and improvements are possible without departing from the concept of this application, and all of these fall within the scope of protection of this application. Therefore, the claims shall be used as the basis. [Explanation of symbols]
