Description

Technical Field

With the rapid development of optoelectronic technology, people have great expectations for the functional research of glass, that is, to make glass have functions such as dimmable light, photovoltaic power generation and regional display according to people's wishes, collectively referred to as functional glass. The structure of these functional glasses is generally a typical laminated glass structure, including outer glass, inner glass and middle layer, and the middle layer of functional glass is a functional layer that realizes the corresponding function through conduction.

DETAILED DESCRIPTION

[0036] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0037] The functional glass with the structure shown in FIG1 is used in a scenario of a vehicle sunroof for explanation. The functional glass includes an outer light-transmitting plate 110, a functional layer 120, an inner light-transmitting plate 130 and a conductive layer 140 which are sequentially stacked and connected. The functional layer 120 is taken as a dimming layer and the conductive layer 140 is a LOW-E (full name: Low Emissivity) film as an example. The LOW-E film is usually coated on the inner surface of the functional glass to reduce the temperature inside the vehicle. The LOW-E film is a metal oxide layer with conductivity. The functional layer 120 includes a first conductor layer 121, an electric drive layer 122 and a second conductor layer 123 which are sequentially stacked along the direction from the outer light-transmitting plate 110 toward the inner light-transmitting plate 130. Among them, the functionalized glass also includes a plurality of adhesive layers 150, and an adhesive layer 150 is provided between any two adjacent layers of the outer light-transmitting plate 110, the first conductor layer 121, the electric drive layer 122, the second conductor layer 123, the inner light-transmitting plate 130 and the conductive layer 140, so as to realize the outer light-transmitting plate 110, the first conductor layer 121, the electric drive layer 122, the second conductor layer 123, the inner light-transmitting plate 130 and the conductive layer 140 are assembled together. Among them, the controller applies alternating current to the first conductor layer 121 and the second conductor layer 123 of the functional layer 120 to drive the electric drive layer 122 to dim. Through research, it is found that the alternating current loaded on the second conductor layer 123 will sense the surface of the LOW-E layer. If the human body touches the glass and also touches a grounded part, the human body becomes a conductor, and the current flows through the human body, and the human body will have an obvious feeling of electric shock.

[0038] Based on the above reasons, the present application provides a vehicle and glass assembly, which can effectively remove the induced charges on the surface of functionalized glass.

[0039] 2 to 5 , an embodiment of the present application provides a glass assembly, which includes a functionalized glass 200 and a grounding connector 300 . The functionalized glass 200 includes a light-transmitting plate 210 , a functional layer 220 and a conductive layer 230 .

[0040] The light-transmitting plate 210 refers to a substrate that is light-transmitting and can provide a certain support. For example, the light-transmitting plate 210 can be, but is not limited to, a glass plate, a transparent polyimide (PI) plate, a transparent plastic plate, and the like.

[0041] In addition, the functional layer 220 is disposed on the light-transmitting plate 210. Optionally, the functional layer 220 includes a first conductor layer 221 and a second conductor layer 222 which are stacked, and the second conductor layer 222 is closer to the conductive layer 230 than the first conductor layer 221. The conductive layer 230 is disposed on the surface of the light-transmitting plate 210, for example, on a side of the light-transmitting plate 210 close to the internal environment, so that it is often touched by users. Of course, the conductive layer 230 can also be disposed on a side of the light-transmitting plate 210 close to the external environment. The conductive layer 230 can be a layer structure having a metal element, such as a metal film layer. Of course, the conductive layer 230 is not limited to a film layer formed by a metal single substance such as a copper film, but can also be a film layer containing a conductive material, composed of a continuously distributed material, or having a grid-like spacing structure.

[0042] For example, a silver-plated layer, a low-emissivity (abbreviated as LOW-E in English, the full name of Low Emissivity) or other heat-insulating layer with conductive properties, an anti-radiation layer, a sound-insulating layer, an electric drive layer 223, etc. can all be used as the conductive layer 230 in this embodiment. Among them, the LOW-E layer can be made of a variety of metals and has good heat insulation effect and light transmittance. Based on this, the first conductor layer 221, the second conductor layer 222, and the conductive layer 230 can all be regarded as conductors, and because there may be insulating media such as air and the electric drive layer 223 between them, a capacitor can be formed.

[0043] The functional layer 220 can realize functions such as dimming and temperature control. When the alternating current applied to the functional layer 220 changes, the light transmittance, light absorption rate and light reflectivity of the functional layer 220 itself may change accordingly, thereby changing the color of the functional layer 220 itself or changing the temperature of the functional layer 220 itself.

[0044] After receiving the electrical signal from the controller, the first conductor layer 221 can drive the functional layer 220 to realize the function. For example, the functional layer 220 can realize the functions of dimming and temperature control. When the alternating current applied to the functional layer 220 changes, the light transmittance, light absorption rate and light reflectivity of the functional layer 220 itself can change accordingly, thereby changing the color of the functional layer 220 itself or changing the temperature of the functional layer 220 itself.

[0045] The grounding connector 300 is electrically connected to the conductive layer 230 , and the grounding connector 300 is also used for grounding.

[0046] In the above-mentioned glass assembly, the conductive layer 230 is grounded through the grounding connector 300. When the functional layer 220 is working and induced charges are generated on the conductive layer 230, since the conductive layer 230 is grounded through the grounding connector 300, the induced charges on the surface of the functionalized glass 200 are effectively removed. There is no need to change the structure of the light-transmitting plate 210, the functional layer 220 and the conductive layer 230, and there is no need to change the material selection and manufacturing process of each layer. That is, the electric shock safety problem of the functionalized glass 200 is solved at an extremely low cost.

[0047] In one embodiment, the functional layer 220 further includes an electric drive layer 223 disposed between the first conductor layer 221 and the second conductor layer 222. Optionally, the electric drive layer 223 includes but is not limited to being an alternating current drive layer.

[0048] Among them, the preparation materials of the electric drive layer 223 may include but are not limited to: PDLC (polymer dispersed liquid crystal), SPD (Suspended Particle Device), GHLC (Guest-Host Liquid Crystal), EC (Electrochromic), LC (liquid crystal), LED (light-emitting diode), heat insulation film, color-changing film, light-guiding film, display film, etc., or a combination of two or more thereof.

[0049] The voltage provided by the first conductor layer 221 and the second conductor layer 222 can drive the transparency of the electric drive layer 223 to change, thereby changing the transparency of the functionalized glass 200. For example, when the material of the electric drive layer 223 includes PDLC, the electric drive layer 223 is a polymer dispersed liquid crystal layer. By applying an AC voltage to the first conductor layer 221, the liquid crystal molecules are flipped to achieve the effect of adjusting the glass haze (corresponding to the transparency). When the functional layer 220 includes SPD, the electric drive layer 223 is a suspended particle layer. Both the first conductor layer 221 and the second conductor layer 222 can be dimmed for the entire surface.

[0050] In one embodiment, the light-transmitting plate 210 can be a single plate or a sandwich structure. In this embodiment, the light-transmitting plate 210 is a sandwich structure as an example, and specifically includes a first light-transmitting plate 211210 and a second light-transmitting plate 212210 that are arranged opposite to each other, and the first light-transmitting plate 211210 and the second light-transmitting plate 212210 form a sandwich space. Among them, the functional layer 220 is arranged in the sandwich space, and the first light-transmitting plate 211210 and the second light-transmitting plate 212210 are used to support the functional layer 220. The first light-transmitting plate 211210, the second light-transmitting plate 212210 and the functional layer 220 can be combined by bonding, lamination, etc.

[0051] The first light-transmitting plate 211210, the functional layer 220, the second light-transmitting plate 212210 and the conductive layer 230 are stacked in sequence. The first light-transmitting plate 211210 is arranged closer to the side where the external environment is than the second light-transmitting plate 212210, and the conductive layer 230 is arranged on the side of the second light-transmitting plate 212210 away from the external environment. The functional layer 220 is closer to the side where the external environment is than the conductive layer 230. By loading an electrical signal, the function of the functional layer 220 can be driven to be realized, and the functional layer 220 can affect the environmental changes on the side away from the external environment. For example, when the functional layer 220 includes an electric drive layer 223, if the transparency is adjusted to a low transparency, the transparency of the side where the conductive layer 230 is incident can be changed to protect privacy.

[0052] In some embodiments, in order to realize that the first conductor layer 221, the electric drive layer 223 and the second conductor layer 222 are combined to form a whole, an adhesive layer 240 is provided between the first conductor layer 221 and the electric drive layer 223, and between the electric drive layer 223 and the second conductor layer 222. In addition, in order to realize that the first light-transmitting plate 211210, the functional layer 220 and the second light-transmitting plate 212210 are combined to form a whole, an adhesive layer 240 is provided between the first light-transmitting plate 211210 and the functional layer 220, and between the functional layer 220 and the second light-transmitting plate 212210.

[0053] As some optional solutions, the first light-transmitting plate 211210 can be omitted from the light-transmitting plate 210, and the second light-transmitting plate 212210 can be retained.

[0054] In some embodiments, the functionalized glass 200 further includes a light blocking layer 250 disposed at the peripheral portion of the light-transmitting plate 210. The visible light transmittance of the light blocking layer 250 is less than or equal to 5%. The connection position of the grounding connector 300 and the conductive layer 230 is located at the peripheral portion of the light-transmitting plate 210 and is located within the region of the light blocking layer 250. In this way, the light blocking layer 250 plays a role in blocking light, that is, the peripheral portion of the light-transmitting plate 210 is arranged to have a black border. The connection position of the grounding connector 300 and the conductive layer 230 is arranged at the black border position, which plays a shielding role on the connection position and has a beautiful appearance.

[0055] In this embodiment, the first light-transmitting plate 211210 is provided with a first surface 2111 and a second surface 2112 disposed opposite to each other, and the second light-transmitting plate 212210 is provided with a third surface 2121 and a fourth surface 2122 disposed opposite to each other. The first surface 2111 faces the external environment, the second surface 2112 and the third surface 2121 are disposed opposite to each other, and the fourth surface 2122 faces the internal environment. Optionally, the light-blocking layer 250 includes but is not limited to being disposed on at least one of the second surface 2112, the third surface 2121, and the fourth surface 2122.

[0056] Please refer to FIG. 2 to FIG. 5. In one embodiment, the grounding connector 300 includes a first electrical connector 310 fixedly mounted on the conductive layer 230. The first electrical connector 310 is provided with a first elastic conductive member 311. Optionally, the first elastic conductive member 311 includes but is not limited to being made of metal material to achieve a conductive effect and has elasticity. The first elastic conductive member 311 abuts against the conductive layer 230 to be electrically connected to the conductive layer 230. In this way, after the first electrical connector 310 is fixedly mounted on the conductive layer 230, the first elastic conductive member 311 abuts against the conductive layer 230, and the conductive effect between the conductive layer 230 and the conductive layer 230 is adjusted and improved accordingly by controlling and adjusting the deformation amount of the first elastic conductive member 311, so as to achieve an effective electrical connection with the conductive layer 230, which can avoid a virtual connection state caused by factors such as manufacturing tolerance and installation tolerance, thereby affecting product performance.

[0057] The "abutment" in this embodiment can be "direct abutment" or "indirect abutment". For example, the first elastic conductive member 311 can be directly abutted against the conductive layer 230 to achieve electrical connection with the conductive layer 230; or it can be indirectly abutted against the conductive layer 230, that is, a conductive element is provided between the conductive layer 230 and the first elastic conductive member 311, such as the second elastic conductive member 400 described below.

[0058] In some embodiments, the first electrical connector 310 further includes a body 312. The body 312 is fixedly mounted on the conductive layer 230, and the first elastic conductive member 311 is mounted on the body 312. The body 312 supports the first elastic conductive member 311, so that the first elastic conductive member 311 and the conductive layer 230 are in contact with each other stably.

[0059] In some embodiments, the main body 312 includes but is not limited to an insulating part, for example, it is obtained by integrally molding with the first elastic conductive part 311 by injection molding, so that the first electrical connector 310 can be mass-produced, and the first elastic conductive part 311 and the main body 312 can be combined to form a whole with high stability; in addition, the first elastic conductive part 311 is embedded in the main body 312, and the main body 312 can prevent the first elastic conductive part 311 from being exposed, thereby protecting the first elastic conductive part 311, preventing the user from touching the first elastic conductive part 311 and generating a sense of electric shock, thereby improving safety.

[0060] Optionally, the main body 312 can be disposed on the conductive layer 230 in a non-detachable manner or in a detachable manner. In this embodiment, the main body 312 is detachably disposed on the conductive layer 230, so that the first electrical connector 310 can be removed according to actual needs, thereby removing the grounding connector 300.

[0061] In some embodiments, the main body 312 is fixed to the conductive layer 230 by, for example, bonding or welding. In order to improve stability, the first elastic conductive member 311 is disposed in the middle portion of the main body 312, and the main body 312 is provided with a connection surface 3122 disposed circumferentially around the first elastic conductive member 311. The connection surface 3122 is fixed to the conductive layer 230 by bonding or welding. In this way, the main body 312 portions around the periphery of the first elastic conductive member 311 are all connected and fixed to the conductive layer 230, and the force is relatively balanced, so that the main body 312 is stably connected to the conductive layer 230. In this embodiment, the connection surface 3122 is bonded and fixed to the conductive layer 230 by, for example, double-sided tape 3123.

[0062] In addition, in order to facilitate the removal of the main body 312 from the conductive layer 230, when the grounding connector 300 is maintained or replaced, the bonding strength between the main body 312 and the conductive layer 230 should not be too strong, so as to ensure that when an external force acts on the main body 312 or the conductive layer 230, the bonding material between the main body 312 and the conductive layer 230 can be broken or loosened, thereby achieving the removal of the main body 312 from the conductive layer 230. As an example, by flexibly adjusting and controlling the bonding area size between the main body 312 and the conductive layer 230, the thickness of the bonding material, or selecting an adhesive material that is easy to be cut or torn, the bonding strength between the main body 312 and the conductive layer 230 can be adjusted, so that the bonding strength is not too small to stably bond the main body 312 and the conductive layer 230 together, and not too large to make it difficult to remove the two under the action of external force.

[0063] Similarly, when the main body 312 is disposed on the conductive layer 230 by welding, in order to facilitate the disassembly operation of the main body 312 and the conductive layer 230, the welding firmness between the main body 312 and the conductive layer 230 cannot be too strong, so as to ensure that when an external force acts on the main body 312 or the conductive layer 230, the welding material between the main body 312 and the conductive layer 230 can be broken or loosened, thereby realizing the disassembly of the main body 312 from the conductive layer 230. As an example, by flexibly adjusting and controlling the welding area size and the thickness of the welding material between the main body 312 and the conductive layer 230, or selecting a welding material that is easy to be cut or torn, the bonding firmness between the main body 312 and the conductive layer 230 can be adjusted, so that the bonding firmness is not too small to stably weld the main body 312 and the conductive layer 230 together, and is not too large to make it difficult to disassemble the two under the action of external force.

[0064] Please refer to Figures 2 to 5. In some embodiments, the glass component further includes a second elastic conductive member 400 disposed between the conductive layer 230 and the first elastic conductive member 311. Optionally, the second elastic conductive member 400 includes but is not limited to being made of metal materials to achieve conductive function and elasticity. The second elastic conductive member 400 is fixedly disposed on the conductive layer 230 and electrically connected to the conductive layer 230, and the first elastic conductive member 311 and the second elastic conductive member 400 are abutted against each other and electrically connected. In this way, compared with the conductive method in which the first elastic conductive member 311 and the conductive layer 230 abut against each other, by adding the second elastic conductive member 400 fixedly disposed on the conductive layer 230 and electrically connected to the conductive layer 230, and using the conductive method in which the first elastic conductive member 311 and the second elastic conductive member 400 abut against each other, it has better conductive performance and can effectively avoid the virtual connection defect with the conductive layer 230.

[0065] In addition, the first elastic conductive member 311 and the second elastic conductive member 400 abut against each other, which can achieve stable connection between the first electrical connector 310 and the conductive layer 230, avoiding the occurrence of a virtual connection state due to factors such as manufacturing tolerance and installation tolerance, which may affect product performance.

[0066] In some embodiments, the second elastic conductive member 400 can be welded on the conductive layer 230, or can be fixed on the conductive layer 230 by conductive adhesive. In this embodiment, welding on the conductive layer 230 is used as an example for expansion. Specifically, as shown in FIG. 2, a silver paste pattern 260 is printed on the conductive layer 230, for example, printed on the light blocking layer 250. Optionally, the silver paste pattern 260 is, for example, rectangular, circular, oval or other shapes. Taking the silver paste pattern 260 as a rectangle, in order to ensure the conductive performance, the minimum area of ​​the silver paste pattern 260 is, for example, 15mm*15mm. In addition, the second elastic conductive member 400 is self-contained with solder, and no surfacing is required, which can ensure the welding appearance after welding. In addition, the second elastic conductive member 400 is, for example, provided with a low thermal conductivity material as a welding height limiter, which can reduce the local instantaneous high temperature conduction while ensuring the solder retention.

[0067] In some embodiments, the main body 312 includes but is not limited to being configured as a cover body or a housing. The main body 312 is not only configured to cover the outside of the first elastic conductive component 311, but also configured to cover the outside of the second elastic conductive component 400. The outer periphery of the main body 312 is provided with a flange 3121, and the connecting surface 3122 is provided on the flange 3121. While ensuring good electrical contact between the first elastic conductive component 311 and the second elastic conductive component 400, it effectively protects the first elastic conductive component 311 and the second elastic conductive component 400.

[0068] Please refer to Figures 3 to 5. In one embodiment, one of the first elastic conductive member 311 and the second elastic conductive member 400 is formed with a plug hole 3111, and the other is inserted into the plug hole 3111 and is interference-fitted or snap-fitted with the plug hole 3111. In this way, the first elastic conductive member 311 and the second elastic conductive member 400 are abutted by mutual plugging, and then electrically connected; in addition, when the interference fit method is used for connection or the snap-fit ​​method is used for connection, the first elastic conductive member 311 and the second elastic conductive member 400 can be closely abutted, so that they have better conductive performance, and the two can be connected and fixed.

[0069] Please refer to FIGS. 3 to 5 . In one embodiment, the plug hole 3111 is formed on the first elastic conductive member 311, and the second elastic conductive member 400 includes a first base 410 and an insertion portion 420 connected to the first base 410. The first base 410 is electrically connected to the insertion portion 420. The first base 410 is fixedly disposed on the conductive layer 230 and is electrically connected to the conductive layer 230. The insertion portion 420 is inserted into the plug hole 3111 and abuts against and is electrically connected to the first elastic conductive member 311. In this way, when the insertion portion 420 is inserted into the plug hole 3111, the first elastic conductive member 311 can be pressed outwardly along the lateral direction F, so that the first elastic conductive member 311 and the second elastic conductive member 400 are in close contact.

[0070] The first elastic conductive member 311 includes a conductive sleeve, which encloses a plug-in hole 3111. A plurality of first openings 3112 are arranged in sequence and spaced around the circumferential direction of the conductive sleeve on the side wall. During the insertion of the insertion portion 420 into the plug-in hole 3111, since the first openings 3112 are arranged on the side wall of the conductive sleeve, the conductive sleeve can be easily deformed after being subjected to the lateral squeezing force of the insertion portion 420, so that the insertion portion 420 can be smoothly inserted into the plug-in hole 3111. Optionally, the conductive sleeve is, for example, configured as a clamping claw sleeve, that is, each first opening 3112 extends from a certain portion of the conductive sleeve to an end face of the conductive sleeve close to the light-transmitting plate 210.

[0071] In some embodiments, one end of the conductive sleeve close to the light-transmitting plate 210 is provided with an opening connected to the plug hole 3111, and the other end of the conductive sleeve is a closed end. When the insertion portion 420 is inserted into the plug hole 3111, the insertion portion 420 also abuts against the other end of the conductive sleeve, so that the other end of the conductive sleeve has a limiting effect on the insertion portion 420, which not only increases the abutting surface, but also improves the stability of the combination of the two.

[0072] In some embodiments, the first base 410 is, for example, a plate, so that the connection between the first base 410 and the conductive layer 230 is a surface connection, which can achieve a stable installation of the second elastic conductive member 400 on the conductive layer 230 and has good conductive performance. Optionally, the first base 410 and the conductive layer 230 include but are not limited to welding connection or conductive adhesive connection.

[0073] In some embodiments, when the outer wall of the insertion portion 420 is subjected to force in the transverse direction F, it can shrink and deform inward, so that the insertion portion 420 can be inserted into the plug hole 3111, and at the same time, it can be elastically abutted against the inner wall of the plug hole 3111. Optionally, the insertion portion 420 includes a plurality of elastic clamping portions arranged in sequence around the insertion direction. In this way, when the insertion portion 420 is inserted into the plug hole 3111, each elastic clamping portion is deformed by force and can shrink inward.

[0074] Each elastic clamping part includes but is not limited to an elastic sheet or an elastic plate. In addition, one end of each elastic clamping part is connected to the first base 410, and the other end is a free end. Each free end is bent, and the part of each free end farthest from the base along the insertion direction forms an arc surface 421. When inserted into the plug hole 3111, the arc surface 421 contacts the first elastic conductive member 311, plays a guiding role, and can reduce collision noise.

[0075] Each free end is bent toward a side close to the central axis of the first base 410 instead of being bent toward a side away from the central axis of the first base 410 , so that the insertion portion 420 can be smoothly inserted into the insertion hole 3111 .

[0076] Please refer to FIG. 4 and FIG. 5. On the basis of the above-mentioned implementation, the conductive sleeve is, for example, embedded and fixed in the main body 312. The main body 312 is, for example, made of an elastic plastic material, and is integrally formed with the conductive sleeve by injection molding. Optionally, in the direction from one end of the conductive sleeve close to the light-transmitting plate 210 to the other end of the conductive sleeve, the thickness of the material coated on the outside of the conductive sleeve by the main body 312 tends to decrease, that is, the coating material on the outside of the portion with an opening of the conductive sleeve is less, and the coating material on the outside of the portion with a closed end of the conductive sleeve is more. As a specific example, the axial cross-sectional profile of the outer wall of the material coated on the outside of the conductive sleeve on the main body 312 is set to a trapezoid. In this way, while ensuring the stable connection between the main body 312 and the conductive sleeve, the elastic properties of the conductive sleeve itself are not hindered.

[0077] In some embodiments, the coating material on the outside of the conductive sleeve is arranged circumferentially around the conductive sleeve, that is, it is designed as a full circle. Of course, it can also be arranged in sections according to the situation to increase the elasticity of the terminal cap.

[0078] In some embodiments, the first elastic conductive member 311 and the second elastic conductive member 400 are not limited to being electrically connected by elastically abutting against each other in the lateral direction F, but may also be electrically connected by elastically abutting against each other in a direction perpendicular to the light-transmitting plate 210 .

[0079] Please refer to FIG. 2 , FIG. 6 and FIG. 9 . In one embodiment, the second elastic conductive member 400 includes a second base 430 and a first elastic abutting plate 440 connected to the second base 430. The first elastic abutting plate 440 is electrically connected to the second base 430. The second base 430 is fixedly disposed on the conductive layer 230 and is electrically connected to the conductive layer 230. The first elastic conductive member 311 includes a second elastic abutting plate 3113, and the second elastic abutting plate 3113 abuts against and is electrically connected to the first elastic abutting plate 440 in a direction perpendicular to the light-transmitting plate 210. In this way, the first elastic conductive member 311 and the second elastic conductive member 400 abut against each other in a surface-to-surface manner in a direction perpendicular to the light-transmitting plate 210, and the contact area between the two is large, so as to have stable conductive performance.

[0080] On the basis of the above-mentioned embodiment, two second bases 430 are provided, and the two second bases 430 are respectively connected to opposite ends of the first elastic abutting plate 440. In addition, the first elastic abutting plate 440 is provided as an arc-shaped abutting plate protruding away from the light-transmitting plate 210. In this way, the elasticity of the first elastic abutting plate 440 is relatively strong, so that when elastically abutting against the second elastic abutting plate 3113, it has relatively stable conductive performance.

[0081] In some embodiments, the second base 430 is, for example, a plate, so that the connection between the second base 430 and the conductive layer 230 is a surface connection, which can achieve that the second elastic conductive member 400 is stably mounted on the conductive layer 230 and has good conductive performance. Optionally, the second base 430 and the conductive layer 230 include but are not limited to being connected by welding or by conductive adhesive bonding.

[0082] Please refer to FIG. 6 and FIG. 9. In one embodiment, the first elastic conductive member 311 further includes an elastic connection structure connected to the second elastic abutting plate 3113. The elastic connection structure is electrically connected to the second elastic abutting plate 3113. The elastic connection structure is connected to the main body 312 of the first electrical connector 310, and the elastic connection structure is a spring 3114 or a spring 3115. In this way, the elastic connection structure can increase the elasticity of the first elastic conductive member 311, so that the first elastic conductive member 311 elastically abuts against the second elastic conductive member 400, thereby having better conductive performance.

[0083] Please refer to FIG. 6 to FIG. 8. In some embodiments, when the elastic connection structure is a spring 3114, two first elastic conductive members 311 are provided, and one second elastic conductive member 400 is provided. The two second elastic abutting plates 3113 are both abutted against one elastic abutting plate, and the forces on the two second elastic abutting plates 3113 are relatively balanced, so that the first electrical connector 310 and the conductive layer 230 can have better conductive properties. In addition, one end of the spring 3114 is embedded in the body 312 by means of integral injection molding, and the other end of the spring 3114 is connected to the second elastic abutting plate 3113. The spring 3114 can provide the second elastic abutting plate 3113 with deformation capability in a direction perpendicular to the light-transmitting plate 210. In addition, the first electrical connector 310 is easy to install and remove on the conductive layer 230.

[0084] Please refer to FIG. 6 and FIG. 7 . On the basis of the above-mentioned embodiment, the two second elastic abutting plates 3113 are each provided with a limiting portion 3116, and the two limiting portions 3116 are respectively limitedly matched with the opposite sides of the first elastic abutting plate 440 along the width direction y. The limiting portions 3116 are, for example, obtained by integrally bending the second elastic abutting plate 3113. The two limiting portions 3116 both play a limiting role, which can prevent the first electrical connector 310 from moving along the width direction y of the second elastic conductive member 400. In addition, the number of the limiting portions 3116 is small, which can reduce the material cost.

[0085] Of course, as some optional solutions, each second elastic abutment plate 3113 is provided with two limiting portions 3116, and the two limiting portions 3116 of each second elastic abutment plate 3113 are respectively limited and matched with the opposite sides of the first elastic abutment plate 440 along the width direction y.

[0086] Please refer to Figures 6 and 7. In some embodiments, the two second bases 430 are provided with protrusions 431 on one side away from each other. Each protrusion 431 is, for example, abutted against the inner wall of the main body 312, specifically abutted against the inner edge of the flange 3121, so as to limit the main body 312 along the length direction x of the second elastic conductive member 400, thereby improving the installation stability of the main body 312 on the light-transmitting plate 210.

[0087] Optionally, a gap of 1 mm to 4 mm is required between the protrusion 431 and the inner wall of the main body 312. In this way, on the one hand, the gap is large, which is convenient for installing the first electrical connector 310; on the other hand, the protrusion 431 serves to limit the displacement of the main body 312 along the length direction x of the second elastic conductive member 400, so that the installation position of the main body 312 along the length direction x moves between ±1 mm and ±4 mm.

[0088] In some embodiments, the length of the spring piece 3114 is set according to the theoretical interference amount of 0.3mm~0.5mm with the surface of the first elastic abutment plate 440 after assembly. If the interference amount is too small, the spring piece 3114 and the first elastic abutment plate 440 may not contact or the contact may be unstable after installation due to manufacturing precision, affecting the function; if the interference amount is too large, the force between the spring piece 3114 and the first elastic abutment plate 440 is too large, and this force generates a force to push the main body 312 open, causing the main body 312 to loosen from the light-transmitting plate 210, resulting in loose installation and easy falling off.

[0089] Similar to the spring 3114, when the elastic connection structure is a spring 3115, please refer to FIG9 , one end of the spring 3115 is embedded and fixed in the main body 312, and the other end is connected to the second elastic abutment plate 3113. The length of the spring 3115 is set according to the theoretical interference amount of 0.3mm~0.5mm with the surface of the first elastic abutment plate 440 after assembly. If the interference amount is too small, the spring 3115 and the first elastic abutment plate 440 may not contact or contact unstably after installation due to manufacturing accuracy, affecting the function; if the interference amount is too large, the force between the spring 3115 and the first elastic abutment plate 440 is too large, and this force generates a force to push the main body 312 open, which will cause the main body 312 to loosen from the light-transmitting plate 210, and the installation is not firm and easy to fall off.

[0090] Please refer to Figure 5. In one embodiment, the grounding connector 300 also includes a second electrical connector 320 and a conductive wire 330. The second electrical connector 320 is electrically connected to the first elastic conductive member 311 through the conductive wire 330. The second electrical connector 320 is configured as a clamping structure, and the clamping structure is used to clamp and fix on the body sheet metal. In this way, the second electrical connector 320 adopts the form of a clamping structure, and the clamping structure is fixed on the body sheet metal by clamping, so as to achieve electrical connection with the body sheet metal, and then achieve grounding; in addition, compared with the method of fastening with fasteners or bonding or other installation methods, the method of clamping and fixing on the body sheet metal by the clamping structure in this embodiment is more convenient to operate.

[0091] In one embodiment, the clamping structure includes two curved clamping pieces 321 arranged at a relative interval. One ends of the two clamping pieces 321 are connected, and the other ends of the two clamping pieces 321 are both set as free ends, and the two clamping pieces 321 cooperate to form a clamping space; each clamping piece 321 is provided with one or more clamping parts 3211 protruding toward each other, and each clamping part 3211 on one clamping piece 321 is arranged in a corresponding position to each clamping part 3211 on the other clamping piece 321.

[0092] In one embodiment, each clamping piece 321 includes but is not limited to being set to an S-shape or a wavy shape, etc. When connected to the body sheet metal, the clamping structure and the body sheet metal can be directly plugged in, with multiple position selectivity, and no sheet metal punching, bolt tightening and other operations are required, which is convenient for original supply operation.

[0093] In a specific embodiment, in order to arrange the connection position between the ground connector 300 and the conductive layer 230 at the peripheral portion of the light-transmitting plate 210, a silver paste pattern 260 is printed at the peripheral portion of the conductive layer 230, and the second elastic conductive member 400 is welded to the silver paste pattern 260. The main body 312 of the first electrical connector 310 is fixed to the conductive layer 230 by adhesive, and elastically abuts against the second elastic conductive member 400 by the first elastic conductive member 311.

[0094] Based on the aforementioned embodiment, the connection position between the grounding connector 300 and the conductive layer 230 avoids the tensile stress area of ​​the light-transmitting plate 210, and for example, the distance from the edge of the light-transmitting plate 210 is ≥30 mm, so as to avoid the stress release in the tensile stress area of ​​the light-transmitting plate 210 during the installation of the first electrical connector 310, thereby preventing the light-transmitting plate 210 from being broken.

[0095] Based on the above embodiments, the first elastic conductive member 311 and the second elastic conductive member 400 need to be made of good electrical conductor materials with a resistivity less than 10 -8 Ω*m, conductivity is 10 5 S / m~10 8 S / m, including but not limited to copper, silver, alloys, etc. Among them, when copper is selected for conductivity, the copper content must be ≥99.9% because impurities have a great influence on conductivity.

[0096] In one embodiment, an embodiment of the present application provides a vehicle, and the vehicle includes the glass assembly of any one of the above embodiments.

[0097] In the above-mentioned vehicle, the conductive layer 230 is grounded through the grounding connector 300. When the functional layer 220 is working and induced charges are generated on the conductive layer 230, since the conductive layer 230 is grounded through the grounding connector 300, the induced charges on the surface of the functionalized glass 200 are effectively removed. There is no need to change the structure of the light-transmitting plate 210, the functional layer 220 and the conductive layer 230, and there is no need to change the material selection and manufacturing process of each layer. That is, the electric shock safety problem of the functionalized glass 200 is solved at an extremely low cost.
