Description
Technical Field

[0002] With the rapid development of the automobile industry and the growing demand of consumers for vehicle functions, functional glass components have been widely valued by vehicle manufacturers and favored by consumers. For example, glass components can be combined with functional components to achieve functions such as lighting, pattern display, image display, privacy, heating, and heat insulation. These functional components are usually superimposed on the surface of the glass component or laminated inside the glass component. When current is applied to the functional component to enable the glass component to function, an induced electric field will be generated around the functional component, and a large amount of charge will be accumulated in the conductive area on the surface of the glass component. When the user touches the conductive area on the surface of the glass component, a sense of electric shock will be generated, which will affect the user experience and pose certain safety hazards.
[0003] In order to eliminate the charge in the existing glass components, the glass components are grounded, for example, the conductive layer of the functional component is grounded or a charge lead-out member bonded to the surface of the glass component and grounded is provided. However, in practical applications, the method of grounding the conductive layer of the functional component is complex, has low reliability and high cost. The charge lead-out member method has the problem of loose fixing, and there is a risk that the charge lead-out member may fall off during the driving of the vehicle, so the charge elimination effect cannot be guaranteed.

[0044] The implementation and use of the embodiments will be discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of specific ways of implementing and using the present disclosure, rather than limiting the scope of the present disclosure. In the description, the expressions of the structural positions of various components, such as the directions of up, down, top, bottom, etc., are not absolute but relative. When the various components are arranged as shown in the figures, these direction expressions are appropriate, but when the positions of the various components in the figures change, these direction expressions also change accordingly.
[0045] In this document, the expression "comprising" or similar expressions synonymous therewith, such as "having", etc., are open-ended and do not exclude additional unlisted elements, steps or components.
[0046] In this document, the terms "first", "second", etc. are not used to limit the order of precedence and the number of components, unless otherwise specified.
[0047] In this document, the meanings of "a plurality of" and "multiple layers" refer to two or more, unless otherwise specifically defined.
[0048] In this document, unless otherwise specifically defined, terms such as "connected" and "attached" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in this document can be understood according to the specific circumstances.
[0049] In this document, the "surface" of the vitreous body or each layer structure of the laminate is bounded by the plane where the length and width of the vitreous body or each layer structure of the laminate are located, and the "edge" is bounded by the plane where the length or width and thickness of the vitreous body or each layer structure of the laminate are located. The "cross-section" of the glass component is taken along the thickness direction of the glass component.
[0050] Hereinafter, the glass assembly is described as being applied to a vehicle window glass, but it does not exclude that the glass assembly can be applied to environments such as doors, windows, curtain walls, aircraft glass or ship glass. When the glass assembly is described as a vehicle window glass for a vehicle, "outside" and "inside" are directions relative to the vehicle body, "outside" refers to the direction away from the vehicle body, and "inside" refers to the direction facing the vehicle body. It should be understood that the vehicle window glass according to the embodiments of the present disclosure includes but is not limited to a front windshield, a rear windshield, a sunroof glass, a door glass or a corner window glass.
[0051] In the ever-changing automotive industry, glass components with functional effects have been widely used in mid-to-high-end models. Functional components combined with glass components realize functions such as lighting, pattern display, image display, privacy, heating, and heat insulation. It has been recognized that when the functional components are powered on, an induced electric field will be generated, and a large amount of charge will be accumulated in the conductive area on the surface of the glass component. When the user touches the conductive area on the surface of the glass component, a sense of electric shock will be generated. Therefore, the existing glass components with functional effects affect the user experience and have certain safety hazards, which cannot satisfy manufacturers and consumers. In order to eliminate the charge, some existing solutions adopt the method of grounding the conductive layer of the functional component, or setting a charge lead-out member bonded to the surface of the glass component and grounded. However, in actual applications, it is found that the method of grounding the conductive layer of the functional component is complex, has low reliability, and is costly, which is not conducive to widespread use. The charge lead-out part is bonded to the surface of the glass component with conductive glue, which has the problem of loose fixation, because conductive glue is usually used to connect conductive components and circuit boards to ensure the normal transmission of current, rather than being applied to a large area of bonding environment on the vehicle, and it is not possible to obtain suitable bonding performance cost-effectively. In addition, the bonding performance of conductive glue is related to factors such as temperature, humidity, and stress. It is easily affected by environmental factors and vehicle vibration and pulling during vehicle driving, and the risk of the charge lead-out part shaking or even falling off is prone to occur, so the charge elimination effect cannot be guaranteed in a long-term and stable manner.
[0052] To this end, the present disclosure provides a glass component, which includes: a glass body; a functional component, which is stacked on the glass body and can be energized to achieve a function; a conductive layer, which is attached to the surface of the glass body; a conductive component, which is electrically connected to the conductive layer and is configured to ground the glass component, wherein the conductive component includes a conductive glue bonded to the conductive layer and a portion of the bonding surface of the conductive component is provided with a primer, or the conductive component includes a conductive glue and a non-conductive glue bonded to the conductive layer, and optionally, a portion of the bonding surface of the conductive component is provided with a primer.
[0053] In this way, the conductive component can ground and conduct the charges accumulated on the glass component, so that the residual charge amount on the glass component is not sufficient to be perceived by the user's touch and is not sufficient to endanger the user's safety during use. The primer is a substance used to evenly coat the surface of the substrate, enhancing the bonding ability between the substrate and the adhesive, improving the bonding strength and long-term stability. And the primer generally does not have conductivity. By adopting the method of providing a primer on a partial bonding surface of the conductive component, since the primer increases the adhesion between the conductive layer and the conductive component, ensuring a firm connection between the conductive component and the conductive layer of the glass component. At the same time, since only a partial bonding surface of the conductive component is provided with a primer, it will not affect the electrical connection between the remaining bonding surfaces of the conductive component (such as the bonding surface formed by the conductive adhesive) and the conductive layer, meeting the effect of reliably conducting charges while enhancing the durability of the firm connection between the conductive component and the conductive layer of the glass component. Compared with the conductive adhesive, the non-conductive adhesive has stronger bonding performance and better environmental stability performance, and can be applied to application environments such as bonding to the surface of the glass component and the vibration and pulling environment of vehicle applications. By adopting the method that the conductive component includes a conductive adhesive and a non-conductive adhesive, the bonding strength and long-term stability of the conductive component and the conductive layer of the glass component can be improved. And since only a part of the conductive component includes the non-conductive adhesive, it will not affect the electrical connection between the bonding surface formed by the conductive adhesive of the conductive component and the conductive layer. It should be understood that although the non-conductive adhesive is included, the conductive component as a whole is still a conductive component. In addition, in the method of providing a primer on a partial bonding surface of the conductive component, the part of the bonding surface formed by the conductive adhesive and the non-conductive adhesive can be the bonding surface of the conductive adhesive and / or the bonding surface of the non-conductive adhesive. For example, in some embodiments, a primer can also be provided on the bonding surface formed by the non-conductive adhesive to further increase the adhesion between the non-conductive adhesive and the surface of the conductive layer of the glass component.
[0054] In some embodiments, the primer is arranged on a part of the bonding surface of the conductive component adjacent to the edge, or around the periphery of the bonding surface adjacent to the edge, or arranged in a substantially middle part of the bonding surface; and / or the non-conductive adhesive is arranged on a part of the conductive component adjacent to the edge, or around the periphery of the conductive component adjacent to the edge, or arranged in a substantially middle part of the conductive component. Regardless of the arrangement method, a substantially uniform bonding part between the conductive component and the conductive layer can be obtained, ensuring a firm bond between the two. And even if the primer and / or the non-conductive adhesive do not have conductivity, the electrical connection between the conductive component and the conductive layer can be ensured through the conductive bonding surface formed by the conductive adhesive.
[0055] Advantageously, the primer covers at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, or at least 90% of the bonding surface of the conductive component, and / or at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, or at least 90% of the bonding surface of the conductive component is formed of a non-conductive adhesive, so as to obtain a reliable electrical connection under the condition of ensuring sufficient stable adhesiveness.
[0056] In the case where the glass assembly is provided with a border, the present disclosure advantageously provides a through hole in the border, the conductive component is bonded to the conductive layer and a part of the conductive component is embedded in the through hole. In this way, the border provides a holding effect on the conductive component, and also ensures a stable connection between the conductive component and the conductive layer of the glass assembly, and does not affect the electrical connection between the conductive component and the conductive layer.
[0057] In a further additional embodiment, the conductive component includes a conductive adhesive bonded to the conductive layer and a primer is provided on a part of the bonding surface of the conductive component, or the conductive component includes a conductive adhesive and a non-conductive adhesive bonded to the conductive layer. Optionally, a primer is provided on a part of the bonding surface of the conductive component, which further enhances the connection between the conductive component and the conductive layer of the glass assembly in the case of implementing the holding effect through the border.
[0058] Advantageously, the conductive components are respectively bonded to the conductive layer of the glass assembly and attached to the component to be connected. When the glass assembly is applied to a window glass, the component to be connected can be a vehicle body sheet metal, and the glass assembly is grounded via the component to be connected (vehicle body sheet metal).
[0059] It should be understood that the glass assemblies of the present disclosure cover single-layer glass bodies and laminated glasses having multiple glass bodies. Figure 1A Exemplarily shown is a glass assembly 100 of an embodiment, including a first glass body 110 and a second glass body 120, and an adhesive layer for attaching the first glass body 110 and the second glass body 120 to each other. Specifically, the adhesive layer includes a first adhesive layer 130a attached to the first glass body 110 and a second adhesive layer 130b attached to the second glass body 120. Depending on different needs, functional components can be arranged on the surface of the first glass body 110 away from the second glass body 120, and / or on the surface of the second glass body 120 away from the first glass body 110, and / or sandwiched between the first glass body 110 and the second glass body 120. Here, "between" covers various arrangement manners where the functional component is directly adjacent or not directly adjacent to the first glass body 110 or the second glass body 120. For example, Figure 1AIn the illustrated embodiment, the functional component 140 is sandwiched between the first glass body 110 and the second glass body 120. The functional component 140 can also be arranged between the first glass body 110 and the first adhesive layer 130a, or between the second glass body 120 and the second adhesive layer 130b. The first adhesive layer 130a and the second adhesive layer 130b are, for example, polyvinyl butyral (PVB), ethylene-vinyl acetate copolymer (EVA), optically clear adhesive (OCA), and other adhesive layers suitable for laminated glass.
[0060] It should be understood that although one functional component is shown in the figure, two functional components or more than two functional components, for example, three, four, etc., multiple functional components stacked in the projection direction perpendicular to the surface of the glass component and / or multiple functional components staggered along the surface direction of the glass body are all feasible, thereby being able to meet a variety of functional effects based on different needs.
[0061] Figure 1A In the illustrated embodiment, the functional component 140 is connected to an external power source so that it can be powered on to achieve functions such as pattern display, image display, privacy, heating, etc. For example, the functional component 140 may be a polymer dispersed liquid crystal (PDLC) film layer. The conductive layer 150 may be configured to be attached to the surface of the second glass body 120, for example, it may be a conductive coating or conductive film layer that achieves a low-emissivity (Low-E, Low Emissivity) function, such as an indium tin oxide (ITO) coating or film layer. During the use of the glass assembly, when an electric current (alternating current) is applied to one or more functional components (such as the functional component 140), an induced electric field is generated, thereby accumulating a large amount of charge on the glass assembly, especially at the conductive layer 150 having conductive properties. Advantageously, the conductive component of the present disclosure is bonded to the conductive layer and is configured to ground the glass assembly, especially Figure 1A In the illustrated embodiment, the conductive component 200 is electrically connected to the conductive layer 150 , so that the charges accumulated in the conductive layer 150 can be led out to the ground.
[0062] In certain embodiments, the glass assembly includes a shielding layer disposed adjacent to an edge of the glass assembly. Figure 1A As shown, the shielding layer 160 can be arranged on the surface of the second glass body 120 away from the first glass body 110. Depending on different needs, the shielding layer can also be arranged between the first glass body and the second glass body, such as Figure 1B In the glass assembly 100-1 of the illustrated embodiment, the shielding layer 160 may be arranged between the first glass body 110 and the first adhesive layer 130a. The shielding layer 160 may be formed of a black printed edge, such as ink or enamel, to shield the circuit or isolate sunlight or ultraviolet rays. Advantageously, in a projection direction perpendicular to the shielding layer 160, the conductive component 200 is arranged in the shielding area of the shielding layer 160, such asFigure 1A and Figure 1B As shown. When the glass assembly 100 or 100-1 is applied to a vehicle window glass, the first vitreous body 110 can face the outside of the vehicle (which can be referred to as the outer glass), and the second vitreous body 120 can face the inside of the vehicle (which can be referred to as the inner glass). Arranging the conductive component 200 within the shielding area of the shielding layer 160 can also prevent the conductive component 200 from being visible outside the vehicle, making the glass assembly more aesthetically pleasing.
[0063] It should be understood that Figure 1A and Figure 1B respectively show different arrangement ways of the shielding layer 160. According to needs, the two ways can also be combined. That is, the shielding layers arranged between the first vitreous body and the second vitreous body and on the surface of one of the first vitreous body and the second vitreous body facing away from the other can be provided on the glass assembly at the same time. When adopting the Figure 1B shown arrangement way, the conductive component 200 can be directly attached to and electrically connected to the conductive layer 150. When adopting the Figure 1A shown arrangement way, if the material of the shielding layer 160 has electrical conductivity, the conductive component 200 can be directly attached to and electrically connected to the shielding layer 160, and the shielding layer 160 is electrically connected to the conductive layer 150. And, Figure 1A and Figure 1B in the shown embodiments, in the projection direction perpendicular to the shielding layer 160, the conductive component 200 is arranged within the shielding area of the shielding layer 160 to prevent the conductive component 200 from being visible outside the vehicle. If Figure 1A the shielding layer 160 of the shown arrangement way is an insulating layer, such as a black printed edge formed by ink or enamel, which generally has poor electrical conductivity. In this case, openings can be formed in the shielding layer 160, and the conductive component is electrically connected to the conductive layer of the glass assembly through the openings. As shown in Figure 2A and Figure 2B multiple openings 170 are formed in the shielding layer 160, and conductive components 200 can be respectively arranged at each opening 170, so that the conductive components 200 are electrically connected to the conductive layer 150 of the glass assembly 100. In an alternative embodiment, the conductive components 200 in the openings 170 can be shielded by an additional shielding layer (such as a shielding layer arranged between the first vitreous body 110 and the first adhesive layer 130a), so that the conductive components 200 are not visible outside the vehicle.
[0064] When the glass assembly is attached to a component to be connected (such as a vehicle body sheet metal), as shown in Figure 3A and Figure 3BAs shown, the edge of the glass component 100 is attached to the vehicle body sheet metal 300, and an electrical connection is achieved between the two through the conductive component 200, so that the glass component 100 is grounded via the vehicle body sheet metal 300. In the illustrated embodiment, the edge 180 of the glass component 100 can abut against the vehicle body sheet metal 300, and the conductive component 200 is disposed in the region bounded between the edge 180 of the glass component 100 and the edge 310 of the vehicle body sheet metal 300. Figure 3B Two conductive components 200 are exemplarily shown. It should be understood that more than two (such as three, four, five, or Figure 2A and Figure 2B six as shown, etc.) conductive components can be arranged at intervals between the glass component 100 and the vehicle body sheet metal 300 to obtain a good effect of eliminating charges. In addition, a seal and a buffer member 400 are provided in the connection area between the glass component 100 and the vehicle body sheet metal 300, and the seal and the buffer member 400 do not affect the electrical connection between the conductive component 200 and the glass component 100 and the vehicle body sheet metal 300. For example Figure 3C as exemplified, in the region where the conductive component 200 is arranged, the conductive component 200 can cover the seal and the buffer member 400 and be electrically connected to the glass component 100 and the vehicle body sheet metal 300 respectively, while the region where the conductive component 200 is not arranged can still maintain the connection between the seal and the buffer member 400 and the glass component 100 and the vehicle body sheet metal 300. Or, as Figure 3D exemplified, in the region where the conductive component 200 is arranged, the conductive component 200 can be electrically connected to the glass component 100 and the vehicle body sheet metal 300 respectively, while the seal and the buffer member 400 can still maintain the connection with the glass component 100 or the vehicle body sheet metal 300.
[0065] The connection of the conductive component 200 with the glass component 100 and the vehicle body sheet metal 300 can have various ways based on different situations. Figures 4A to 4D The connection of the conductive component with the conductive layer of the glass component is exemplarily shown respectively, Figures 5A to 5D The connection of the conductive component with the vehicle body sheet metal 300 is exemplarily shown respectively.
[0066] In some embodiments, the conductive component 200 may be a conductive adhesive itself, or the conductive component 200 may include a conductor and a conductive adhesive, and the conductor is bonded to the conductive layer through the conductive adhesive. As mentioned above, the conductive adhesive is an adhesive with conductive properties, and the bonding strength of the conductive adhesive is related to factors such as temperature, humidity, pressure, and strain rate. In the application environment of the window glass, the vibration and bump during vehicle driving are likely to affect the adhesion between the conductive adhesive and the conductive layer on the surface of the glass body. In addition, the surfaces of the glass body and the conductive layer attached thereto are usually highly smooth, which further affects the adhesion between the conductive adhesive and the conductive layer, and thus affects the charge conduction effect of the conductive component. In the solution of the present disclosure, since a primer is provided on a partial bonding surface of the conductive component and / or the conductive component includes a non-conductive adhesive, the primer and / or the non-conductive adhesive increase the adhesion of the conductive layer of the glass assembly to the conductive component, can effectively ensure the firm bonding between the conductive component and the conductive layer of the glass assembly, and thus effectively ensure the charge conduction effect of the conductive component.
[0067] In some embodiments, as Figure 4A shown, the conductive component 200 may include a conductor 210 and a conductive adhesive 220, and the conductor 210 is bonded to the surface of the glass assembly through the conductive adhesive 220, specifically, the surface of the second glass body 120 provided with a conductive layer. For simplicity, the conductive layer is omitted in the figure. Figure 4A In the shown embodiment, a primer 230 (and / or the conductive component includes a non-conductive adhesive bonded to the conductive layer of the glass assembly) may be provided on a partial surface where the conductive adhesive 220 is bonded to the conductive layer of the glass assembly. For example, according to different needs, the primer 230 may first be coated on the area of the surface of the conductive layer of the glass assembly where the conductive component needs to be bonded (such as a part near the edge of the bonding surface of the conductive component, or a perimeter around the edge of the bonding surface, or a substantially middle part of the bonding surface), and then the conductive adhesive 220 of the conductive component is bonded to the corresponding area. At this time, it can be considered that a primer is provided on a partial bonding surface of the conductive component. As described above, the primer 230 (and / or the non-conductive adhesive) helps to increase the adhesion of the surface of the conductive layer of the glass assembly to the conductive component, ensure the stable connection between the conductive component and the conductive layer of the glass assembly, and at the same time, in the part without the primer 230 (and / or the non-conductive adhesive), the conductive adhesive 220 can ensure a reliable electrical connection with the conductive layer of the glass assembly.
[0068] In some embodiments, the glass assembly includes a border. According to different needs, the border may include a first border extending along the surface of the glass body and a second border extending along the edge of the glass body. As Figure 4BIn the illustrated embodiment, still taking the second vitreous body 120 provided with a conductive layer as an example, and for the sake of simplicity, the conductive layer is omitted. The edge wrap may include a first edge wrap 510 extending along the surface of the second vitreous body 120, and a second edge wrap 520 extending from the first edge wrap 510 along the edge of the second vitreous body 120. Advantageously, the conductive component is arranged in the edge wrap area of the glass assembly so as to make the appearance of the glass assembly beautiful. In this case, the conductive component attached to the conductive layer of the glass assembly can be led out of the edge wrap by opening a hole in the edge wrap, thereby realizing the electrical connection with the vehicle body sheet metal 300.
[0069] In Figure 4B In the illustrated embodiment, the first edge wrap 510 is provided with a first through hole 511. Advantageously, in the projection direction perpendicular to the first edge wrap 510, the edge of the conductive component in contact with the surface of the first edge wrap 510 facing the second vitreous body 120 extends beyond the edge of the first through hole 511, for example, extending beyond at least 2 mm, at least 3 mm, at least 4 mm or even more, so as to reliably fix the conductive component through the edge wrap. In some embodiments, a part of the conductor 210 is embedded in the first through hole 511. It should be understood that the partial embedding of the conductive component in the through hole includes that a part of the conductive component is located in the through hole and is flush with the surface of the edge wrap away from the vitreous body, that is, as Figure 4B shown in the illustrated embodiment, a part of the conductor 210 is located in the first through hole 511 and is flush with the surface of the first edge wrap 510 away from the second vitreous body 120. In some embodiments, the partial embedding of the conductive component in the through hole further includes that a part of the conductive component extends through the through hole and extends beyond the surface of the edge wrap away from the vitreous body, that is, as Figure 4C shown in the illustrated embodiment, a part of the conductor 210 is embedded in the first through hole 511 and can extend out of the first through hole 511 and extend beyond the surface of the first edge wrap 510 away from the second vitreous body 120. In addition, in some embodiments, the partial embedding of the conductive component in the through hole further includes that a part of the conductive component extends through the through hole and at least covers a part of the surface of the edge wrap away from the vitreous body. For example, Figure 4C The difference between the illustrated embodiment and Figure 4B the illustrated embodiment is also that a part of the conductor 210 extends through the first through hole 511 and covers a part of the surface of the first edge wrap 510 away from the second vitreous body 120. In other words, Figure 4B the conductor 210 in the illustrated embodiment may have a substantially T-shaped cross-sectional shape, Figure 4C the conductor 210 in the illustrated embodiment may have a substantially I-shaped or H-shaped cross-sectional shape, which helps to provide a firm connection between the conductor 210 (conductive component) and the conductive layer on the second vitreous body 120 through the first edge wrap 510.
[0070] In Figure 4DIn the illustrated embodiment, the second edge wrapping 520 may be provided with a second through hole 521. A part of the conductor 210 may extend through the second through hole 521 and extend beyond the surface of the second edge wrapping 520 that is away from the second vitreous body 120. And in this way, the first edge wrapping 510 is not provided with a through hole for a part of the conductive component to be embedded. Advantageously, when the second edge wrapping 520 is provided with the second through hole 521, the surface of the first edge wrapping 510 facing the second vitreous body 120 at least contacts a part of the conductor 210 (conductive component). For example Figure 4D In the illustrated embodiment, in the projection direction perpendicular to the first edge wrapping 510, the part of the conductor 210 (conductive component) that is not embedded in the second through hole 521 is completely located within the area of the first edge wrapping 510 and contacts the surface of the first edge wrapping 510 facing the second vitreous body 120, so that a firm connection can be provided between the conductor 210 (conductive component) and the conductive layer on the second vitreous body 120 through the first edge wrapping 510 and the second edge wrapping 520 and the conductive component can be led out. In some embodiments not shown, in the projection direction perpendicular to the first edge wrapping 510, the part of the conductor 210 (conductive component) that is not embedded in the second through hole 521 may be partially located within the area of the first edge wrapping 510 and contact the surface of the first edge wrapping 510 facing the second vitreous body 120, and a firm connection can also be provided between the conductor 210 (conductive component) and the conductive layer on the second vitreous body 120 through the first edge wrapping 510 and the second edge wrapping 520 and the conductive component can be led out. Similarly, the part of the conductor 210 embedded in the second through hole 521 may also be located in the second through hole 521 according to different needs and be flush with the surface of the second edge wrapping 520 that is away from the second vitreous body 120, or the part of the conductor 210 embedded in the second through hole 521 extends through the second through hole 521 and at least covers a part of the surface of the second edge wrapping 520 that is away from the second vitreous body 120.
[0071] It should be understood that due to the fragility of the glass, the attachment between the conductive component and the conductive layer of the glass component is mainly by bonding. In some embodiments not shown, Figures 4A to 4D The illustrated embodiments can be combined for use according to different needs. For example Figures 4B to 4D In the attachment manner of the illustrated conductive component and the edge wrapping, it can be combined with Figure 4A the manner in which the illustrated conductive component has a primer (and / or non-conductive adhesive), Figure 4B and Figure 4C the attachment manner of the illustrated conductive component and the first edge wrapping can also be combined with Figure 4D the attachment manner of the illustrated conductive component and the second edge wrapping, that is, both the first edge wrapping and the second edge wrapping can be provided with through holes into which parts of the conductive component can be embedded, which will not be elaborated here.
[0072] The connection between the conductive component 200 and the vehicle body sheet metal 300 can also be achieved by bonding. Advantageously, the conductive component includes a conductive adhesive bonded to the vehicle body sheet metal and a primer is provided on a partial bonding surface of the conductive component, or the conductive component includes a conductive adhesive and a non-conductive adhesive bonded to the vehicle body sheet metal. Optionally, a primer is provided on a partial bonding surface of the conductive component. Preferably, due to the high strength of the vehicle body sheet metal, in some alternative or additional embodiments, the connection between the conductive component and the vehicle body sheet metal 300 can adopt a connection method that is more firm than bonding. Similarly, the conductive component can be a conductive adhesive itself or include a conductor and a conductive adhesive. Figures 5A to 5D Still taking the connection between the conductor 210 and the vehicle body sheet metal 300 as an example.
[0073] In some embodiments, the vehicle body sheet metal 300 can be provided with through holes 310, such as Figure 5A As shown, the conductor 210 of the conductive component can be connected to the vehicle body sheet metal 300 via a fastener 600 (such as a bolt) passing through the through hole 310. Optionally, when the conductor 210 of the conductive component has elasticity, the conductor 210 can pass through the through hole 310 by itself to be connected to the vehicle body sheet metal 300. And, to obtain a more stable connection between the conductor 210 and the vehicle body sheet metal 300, a clamping portion in the form of, for example, barbs 212 can be provided on the part of the embedding end 211 of the conductor 210 extending out of the through hole 310 after being embedded in the through hole 310 to hold with the surface of the vehicle body sheet metal away from the glass component 100. Figure 5B Exemplarily shows two symmetrically arranged barbs 212. Figure 5C Exemplarily shows one barb 212.
[0074] In some embodiments, the conductive component can be connected to the vehicle body sheet metal 300 by covering the edge of the vehicle body sheet metal 300. As Figure 5D As shown, the conductor 210 of the conductive component can be configured in the form of a clip, for example, to clamp on the edge of the vehicle body sheet metal 300, thereby realizing the fixation between the two.
[0075] Regardless of the arrangement and combination method, the glass component of the present disclosure advantageously grounds and conducts out the charges accumulated on the surface of the glass component due to the energized use of the functional components through the conductive component, and a reliable and stable connection can be achieved between the conductive component and the conductive layer of the glass component, improving the use safety and user experience of the glass component. When applied to a window glass, by bonding the conductive component to the conductive layer of the glass component and attaching it to the vehicle body sheet metal respectively, a stable connection between the conductive component and the conductive layer of the glass component and between the conductive component and the vehicle body sheet metal can be realized, and the conductive component can be grounded more directly and reliably, avoiding potential electric shock risks and ensuring user safety. It should be understood that in the possible embodiments that have been described or not described, various improvement methods can be used independently or in combination, facilitating the glass component of the present disclosure to be applied to various occasions.

However, it can be understood that under the creative concept of the present disclosure, those skilled in the art can make various changes and improvements to the above-disclosed concept, but they all fall within the protection scope of the present disclosure.
