Description

Technical Field

[0002] Smart glass is a type of laminated optoelectronic glass in which a dimming functional layer, such as a liquid crystal film, is sandwiched between two glass substrates and integrally formed under high temperature and pressure through an intermediate adhesive layer.

[0052] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0053] In related technologies, electrical connectors for dimming films, such as wire harness connectors, are typically designed directly on the surface or back of the film and connected to the power supply via soldering, plugging, or gluing. However, this arrangement has several drawbacks: First, the wire harness connector protrudes from the overall glass outline, making it highly susceptible to pulling or scratching during cleaning, handling, or installation, leading to frequent bending and potentially causing fatigue fracture at the solder joints or detachment at the glued joints, resulting in poor connection reliability. Second, because the existing wire harness connectors are located in the middle or other non-edge areas of the dimming film, precise alignment and fixation are required in confined spaces during installation, making the operation extremely inconvenient and assembly inefficient. Moreover, if the exposed connector is damaged and needs repair or replacement, the entire dimming film often needs to be disassembled, resulting in high maintenance costs and long maintenance times. Finally, the exposed wire harness and connectors affect the integrity of the glass surface and detract from its aesthetics.

[0054] To address the aforementioned issues, this application provides a glass assembly and vehicle. By recessing at least a portion of the side edges of the composite functional layer inward to form a groove, on one hand, the electrical connector and the first connection structure are internally protected within the groove, preventing them from direct external impact. This solves the problem in related technologies where electrical connectors are easily damaged or detached due to external impact, thus improving the reliability of the electrical connector connection. On the other hand, this design achieves complete concealment of the electrical connector, resulting in a clean and smooth glass appearance and enhancing the product's aesthetics. Furthermore, the interface layout on the side edges provides an intuitive and convenient operating channel for installation and maintenance, simplifying the operation process, improving efficiency, saving maintenance costs and time, and enhancing the user experience.

[0055] The following will combine Figure 1 The specific structure of the vehicle provided in the embodiments of this application will be described.

[0056] Reference Figure 1 As shown, this embodiment provides a vehicle 200, which can be an electric vehicle, a traditional fuel vehicle, or a commercial vehicle. This embodiment does not limit the type of vehicle.

[0057] Reference Figure 1 As shown, vehicle 200 includes body 210 and glass assembly 100. It can be understood that body 210, as the basic load-bearing structure of vehicle 200, provides a mounting carrier for glass assembly 100. Glass assembly 100 is mounted on body 210 to ensure assembly stability.

[0058] In this embodiment, the installation position of the glass assembly 100 is not limited. For example, the glass assembly 100 may be installed on the top of the vehicle body 210 to serve as a sunroof of the vehicle 200; or, the glass assembly 100 may be installed at the front end of the vehicle body 210 to serve as a windshield of the vehicle 200; or, the glass assembly 100 may be installed at the rear end of the vehicle body 210 to serve as a rear windshield of the vehicle 200; or, the glass assembly 100 may be installed at the side of the vehicle body 210 to serve as a side windshield of the vehicle 200, etc.

[0059] In this embodiment, refer to Figure 1 As shown, the explanation mainly takes the glass assembly 100 installed on the roof as an example.

[0060] It should be noted that the vehicle 200 may also include a power supply, which is located in the vehicle body 210. For example, the power supply may be located inside the vehicle, which helps to prevent external impurities from damaging the power supply and thus ensure its normal operation. The power supply may include a second connection structure that interfaces with the first connection structure 160 of the glass assembly 100 to electrically connect the power supply to the composite functional layer 120, thereby supplying power to the electrical functional layer 123 of the composite functional layer 120.

[0061] It should be noted that this embodiment does not limit the type of the electrical functional layer 123. For example, the electrical functional layer 123 can be a light-emitting film layer; or, the electrical functional layer 123 can be a display film layer; or, the electrical functional layer 123 can be a dimming film layer.

[0062] In this embodiment, the description mainly uses the electrical functional layer 123 as a dimming film layer, and the description mainly uses dimming glass as a dimming glass.

[0063] By setting the second connection structure to mate with the first connection structure 160, quick plug-in connection can be achieved, significantly improving the fatigue resistance of the electrical connector 130, greatly simplifying the installation process and improving assembly efficiency. Moreover, compared with the integrated design of connector and wire harness in related technologies, which requires replacement of the whole structure after damage and disassembly of glass or diaphragm, the electrical connector 130 of this application does not require disassembly of the entire electrical functional layer when damaged, reducing maintenance costs and saving maintenance time.

[0064] The vehicle 200 may also include a controller, which is configured to adjust the color of the dimming glass and change the viewing pattern on the dimming glass. In this way, the finished glass not only has the light-blocking properties of ordinary sunroof glass, but also has the functions of color adjustment and changing the viewing pattern when powered on.

[0065] For example, the controller can be configured to change the color of the dimming glass from neutral to colored. Specifically, since the dimming film layer is made of polymer liquid crystal material, when the dimming glass is de-energized, the polymer liquid crystal material in the middle of the glass is disordered, preventing light from passing through the glass, and the effect seen is a milky white opaque state; when the dimming glass is energized, under the action of the electric field, the polymer liquid crystal material in the middle of the glass is ordered, allowing light to pass through the glass, and the effect seen is a transparent and colorless glass state.

[0066] For example, the controller can switch the dimming glass from a single color to multiple colors. For instance, the controller can be configured to gradually change the color of the dimming film layer from the inside out or from the outside in. This embodiment is not limited to this. For example, the controller may have a built-in control program to implement the above-mentioned control functions, and the controller may be configured to be remotely controlled and display the functions on the vehicle's display screen for user operation and selection.

[0067] The following will combine Figures 2 to 13 The specific structure of the glass assembly provided in the embodiments of this application will be described.

[0068] This application provides a glass assembly 100, including a glass substrate 110, a composite functional layer 120, and an electrical connector 130, wherein the composite functional layer 120 is disposed within the glass substrate 110.

[0069] It is understood that the composite functional layer 120 is a core optical component, such as a polymer-dispersed liquid crystal film; by applying or cutting off voltage, the arrangement of liquid crystal molecules inside it will change, thereby switching between a transparent state and a fogged (opaque) state.

[0070] It should be noted that the electrical connector 130 in this embodiment can be a wire harness connector.

[0071] In order to reduce the problem that the electrical connector 130 in related technologies is easily damaged or detached due to external impact, in this embodiment of the application, reference is made to... Figures 2 to 5 As shown, at least a portion of the side edges of the composite functional layer 120 are recessed inward to form a groove 121, with the opening of the groove 121 facing the outer side of the glass substrate 110. (Refer to...) Figure 6 and Figure 7 As shown, the electrical connector 130 is embedded in the groove 121 and is electrically connected to a portion of the composite functional layer 120.

[0072] It should be noted that the method of forming the groove 121 is not limited. For example, before the composite functional layer 120 is laid on the glass substrate 110, a notch of a specific shape is punched or engraved at a predetermined position on its side edge using a precision cutting mold or laser engraving equipment; the composite functional layer 120 with the notch is aligned and stacked with the glass substrate 110; it is sent into an autoclave and laminated under high temperature and high pressure conditions. At this time, the adhesive layer will melt and fill all the gaps between the glass substrate 110 and the composite functional layer 120, but since the notch of the composite functional layer 120 forms a cavity, the adhesive material cannot fill this area; after lamination, the cavity reserved by the notch is solidified at the side edge of the composite functional layer 120 to form the final groove 121.

[0073] For example, the complete composite functional layer 120 can be laminated with the glass substrate 110 to form a complete glass assembly 100 with flat edges. A grinding device can be used to precisely position and grind specific positions on the side edges to remove some of the material from the glass substrate 110, the adhesive layer and the composite functional layer 120, thereby processing the required groove 121.

[0074] In this embodiment, the shape and size of the groove 121 are not limited, and can be flexibly adjusted according to actual needs. For example, the cross-sectional shape of the groove 121 may include, but is not limited to, rectangle, square, circle, V-shape, etc. Its main function is to provide a receiving space, and its ability to stably accommodate the electrical connector 130 is within the protection scope of this application.

[0075] In this embodiment, the number and location of the grooves 121 are not limited. For example, the grooves 121 can be located in the middle of the side edge of the composite functional layer 120 or near the corner, or in any suitable location; or, they can be flexibly located on any of the upper, lower, left, or right edges of the composite functional layer 120, or distributed in a combination, depending on product requirements.

[0076] The number of grooves 121 can be set to one or more according to power supply or signal requirements. For example, a groove 121 can be provided on one side edge of the composite functional layer 120; or, grooves 121 can be provided on multiple different side edges respectively, for example, one side is used for power input and the other side is used for control signal reception. This embodiment does not limit this.

[0077] In this embodiment, refer to Figure 8 As shown, the explanation mainly takes the example of opening a groove 121.

[0078] By embedding the electrical connector 130 within the groove 121, it is physically protected by the groove wall, thereby reducing the risk of breakage or detachment due to direct force during handling or installation, and improving the reliability of the electrical connector 130 connection.

[0079] Continue to refer to Figure 9 and Figure 10 As shown, in this embodiment of the application, a first connecting structure 160 may also be included, which is embedded in the groove 121; see reference Figure 11 As shown, the first connection structure 160 encloses at least a portion of the electrical connector 130, and the first connection structure 160 is configured to mate with a second connection structure of the power supply to enable electrical connection between the electrical connector 130 and the power supply.

[0080] Understandably, the first connection structure 160, as an interface fixed to the glass assembly 100, primarily functions to form a fast and stable electrical and mechanical connection with the second connection structure from the power supply.

[0081] Specifically, the first connecting structure 160 may have a first conductive contact inside, and the second connecting structure may have a second conductive contact inside. When the two are properly aligned, their built-in locking mechanism provides a clear indication of alignment, preventing accidental detachment due to vibration or other reasons. Simultaneously with the completion of the mechanical connection, the first conductive contact and the second conductive contact make contact, thereby enabling the electrical connector 130 to conduct electricity with the power supply, forming a highly reliable electrical path through which the power supply can then supply power to the composite functional layer 120.

[0082] It should be noted that the first conductive contact can be a static conductive contact, and the second conductive contact can be a flexible conductive element, such as a spring pin or a metal spring. The flexible design helps ensure continuous and stable pressure between the contact surfaces, thereby ensuring the formation of a low-resistance, highly reliable electrical path. This embodiment does not limit this aspect.

[0083] When maintenance or replacement is required, simply triggering the unlocking mechanism, such as pressing the release button, will allow the second connection structure to be safely and quickly separated from the first connection structure 160. The entire process requires no additional disassembly tools, enabling quick plug-in and unplugging connections. This significantly improves the fatigue resistance of the electrical connector 130, greatly simplifies the installation process, and increases assembly efficiency. Furthermore, when the electrical connector 130 is damaged and requires repair, it is not necessary to completely disassemble the electrical functional layer 123, reducing maintenance costs.

[0084] The surfaces of the first and second conductive contacts can be plated with gold or silver to improve their conductivity and oxidation resistance.

[0085] In this embodiment, the specific structure of the first connecting structure 160 and the second connecting structure is not limited, and can be set according to actual needs.

[0086] In some embodiments, the first connecting structure 160 can be a male snap-fit ​​connector, and the second connecting structure can be a female snap-fit ​​connector, both connected to the power supply of the vehicle 200. The first connecting structure 160 and the second connecting structure are connected by a snap-fit ​​engagement. During the connection process, the female snap-fit ​​connector is inserted into the male snap-fit ​​connector until the locking mechanism inside the female snap-fit ​​connector and the male snap-fit ​​connector engages, emitting an indicator sound to indicate that the connection is in place. The above connection method is robust and has good vibration resistance.

[0087] In some embodiments, the first connecting structure 160 can be a first magnetic attractor, such as a connector including a permanent magnet, and the second connecting structure can be a second magnetic attractor, such as a connector containing ferromagnetic material. When the two come close, they will automatically attract and align under the action of magnetic force, and the first connecting structure 160 and the second connecting structure are connected by magnetic attraction. The above connection method can detach itself when subjected to external pulling force, thereby helping to reduce damage to the wiring harness or connector itself.

[0088] In some embodiments, wireless power supply can also be used, eliminating the need for a physical connection and requiring only the integration of an additional receiving coil. This embodiment does not limit this approach.

[0089] In this embodiment, the specific materials of the first connecting structure 160 and the second connecting structure are not limited, and can be set according to actual needs.

[0090] In some embodiments, the first connecting structure 160 may be made of polyoxymethylene (POM) or flexible nylon; the second connecting structure may also be made of POM or flexible nylon. POM possesses high rigidity, strength, fatigue resistance, and a low coefficient of friction, resulting in a robust structure with a long service life. Nylon flexible material exhibits good toughness, impact resistance, and a certain degree of flexibility. In the vibration environment of a vehicle (200 km / h), it can absorb some energy, preventing brittle fracture. Furthermore, it helps the locking mechanism to generate appropriate elastic deformation, enabling smooth locking and releasing.

[0091] In some embodiments, the second connection structure may include a waterproof sealing ring made of silicone. In some embodiments, the connector may also be designed as a rotatable structure, which helps to further reduce the risk of wire harness bending. This embodiment does not limit these aspects, and the specific configuration can be made according to actual needs.

[0092] Therefore, the glass assembly 100 provided in this embodiment proposes an integrated solution of "fully embedded and snap-fit ​​quick connection", which completely integrates and protects the electrical connector 130 and the first connection structure 160 in the groove 121, leaving only the interface contacts for quick connection and power-off interaction with the outside. This protects it from direct external impact, solving the problem that the electrical connector 130 is easily damaged or detached due to external impact in related technologies, and improving the reliability of the electrical connector 130 connection. The interface layout on the side edge provides an intuitive and convenient operation channel for installation and maintenance, simplifying the operation process, improving efficiency, saving maintenance costs and time, and enhancing the user experience.

[0093] In one embodiment, reference Figure 3 and Figure 5 As shown, the first connection structure 160 may be flush with the outer edge of the glass substrate 110; or, the electrical connector 130 may be flush with the outer edge of the glass substrate 110. This embodiment does not limit this.

[0094] It is understandable that "flush" means that, when viewed from the side, the first connecting structure 160 and the electrical connector 130 are on the same plane as the outer contour surface of the glass substrate 110, forming a continuous and smooth edge transition.

[0095] The above design ensures that the smooth edges are less prone to accumulating dust and water stains, facilitating daily cleaning and maintenance. It also makes it easier to apply sealant or install flat sealing rings around the joints, achieving a more effective dustproof and waterproof seal. Simultaneously, it effectively maintains the smoothness of the glass edges, avoiding visual abruptness.

[0096] In one embodiment, the first connection structure 160 may be recessed into the outer edge of the glass substrate 110; or, alternatively, the electrical connector 130 may be recessed into the outer edge of the glass substrate 110. This embodiment does not limit this.

[0097] It is understandable that "recessed" means that the first connecting structure 160 and the electrical connector 130 are recessed inwards by a certain distance relative to the outer contour of the glass substrate 110.

[0098] The above design effectively reduces direct scratches or impacts from the sides during handling or daily use, thereby maximizing the mechanical reliability of the connection.

[0099] In this embodiment, the example of the first connecting structure 160 being flush with the outer edge of the glass substrate 110 is used for illustration. (Refer to...) Figure 7 As shown, the example is that the electrical connector 130 is flush with the outer edge of the glass substrate 110.

[0100] In one embodiment, the electrical connector 130 can be embedded in the groove 121 by an insert injection molding process; or, the first connection structure 160 can be embedded in the groove 121 by an insert injection molding process. This embodiment does not limit this.

[0101] It should be noted that the "insert injection molding process" involves placing a pre-processed insert into a mold cavity, then injecting molten plastic to encapsulate the insert, and finally cooling and molding it into a complete, indivisible composite component. It can be understood that the shape of this cavity corresponds to the required groove 121 structure.

[0102] For example, the electrical connector 130 is embedded inside the glass. A space is reserved inside the glass through a lamination process, and the electrical connector 130 is embedded and then encapsulated. For example, a curing adhesive can be filled and cured under high pressure and high temperature to ensure that the electrical connector 130 is integrated with the glass substrate 110.

[0103] Among them, the lamination process refers to precisely stacking two or more glass substrates 110 with the interlayer material in between, and then permanently bonding them into a strong whole through high temperature and high pressure treatment.

[0104] In one embodiment, reference Figure 4 , Figure 5 , Figure 7 as well as Figure 9 As shown, the glass substrate 110 may include an outer glass plate 111 and an inner glass plate 112 stacked along a first direction, with the inner glass plate 112 configured to face the inside of the vehicle; a composite functional layer 120 is disposed between the outer glass plate 111 and the inner glass plate 112 along the first direction.

[0105] In this embodiment, the first connecting structure 160 can be bonded to the outer glass plate 111; or, the first connecting structure 160 can be bonded to the inner glass plate 112; or, the first connecting structure 160 can be bonded to both the outer glass plate 111 and the inner glass plate 112 simultaneously.

[0106] For example, after the first connecting structure 160 is embedded, transparent silicone sealant can be applied for filling. After curing, it forms an elastic protective layer, which can achieve waterproofing and dustproofing while maintaining the flatness of the glass edges and avoiding abrupt visual impact. Thus, through concealed wiring harness connectors, high-octane ink printing, and a stable snap-fit ​​design, both the product's functional reliability and aesthetics are improved.

[0107] In this embodiment, refer to Figure 3 , Figure 9 and Figure 10 As shown, the composite functional layer 120 may include a first adhesive layer 122, an electrical functional layer 123, and a second adhesive layer 124 stacked along a first direction. (Refer to...) Figure 5 , Figure 7 , Figure 9 as well as Figure 11 As shown, the first adhesive layer 122 is disposed between the outer glass plate 111 and the electrical functional layer 123 along the first direction, and the second adhesive layer 124 is disposed between the electrical functional layer 123 and the inner glass plate 112 along the first direction; the electrical connector 130 is electrically connected to the electrical functional layer 123.

[0108] It should be noted that the first direction can be as follows: Figure 5 , Figure 7 and Figure 9 The middle arrow points in the x direction.

[0109] In this embodiment, the material of the electrical functional layer 123 can be any of the following materials: PDLC film (polymer dispersed liquid crystal film), EC film (electrochromic film), or SPD film (suspended particle device film). This embodiment does not limit the choice of material.

[0110] In this embodiment, the material of the first adhesive layer 122 can be any of the following materials: PVB (polyvinyl butyral), EVA (ethylene-vinyl acetate copolymer), TPU (thermoplastic polyurethane elastomer), SGP (ionic interlayer film), etc. The material of the second adhesive layer 124 can be any of the following materials: PVB (polyvinyl butyral), EVA (ethylene-vinyl acetate copolymer), TPU (thermoplastic polyurethane elastomer), SGP (ionic interlayer film), etc. This embodiment does not limit the choice of material.

[0111] In this embodiment, the outline dimensions of the first adhesive layer 122 and the second adhesive layer 124 can be the same, and the outer outline of the electrical functional layer 123 can be smaller than the outline dimensions of the adhesive layers, or it can be the same as the outline dimensions of the adhesive layers. This embodiment does not limit this.

[0112] By adopting the above-described configuration, the outer glass panel 111 and the inner glass panel 112 provide robust physical protection for the composite functional layer 120, shielding it from scratches, impacts, and environmental corrosion. The first adhesive layer 122 and the second adhesive layer 124 not only achieve a stable bond but also act as a safety buffer, preventing shards from flying when the glass is impacted and helping to ensure that the electrical functional layer 123 does not directly bear mechanical stress. Therefore, this fully enclosed structure, in which the electrical functional layer 123 is completely embedded within the glass and adhesive layers, not only enables intelligent dimming but also helps improve the safety performance of traditional laminated glass.

[0113] In one embodiment, the side edge of the electrical functional layer 123 may be recessed into the side edge of the first adhesive layer 122; or, the side edge of the electrical functional layer 123 may be recessed into the side edge of the second adhesive layer 124. It should be noted that "recessed" means that in the laminated structure, the side edge of the electrical functional layer 123 is more recessed towards the inner center of the glass than the side edges of the adjacent first adhesive layer 122 and second adhesive layer 124.

[0114] If the side edges of the electrical functional layer 123 do not shrink, i.e., the edges of each layer are aligned, the edges of the electrical functional layer 123 are directly exposed to the edge of the assembly. Since the surface of the electrical functional layer 123, especially the dimming film layer, is usually non-adhesive, this may result in insufficient bonding area between the first adhesive layer 122, the second adhesive layer 124 and the edge area of ​​the electrical functional layer 123, resulting in weak adhesion and easy delamination and separation at the edges.

[0115] Therefore, in order to prevent interlayer delamination, in this embodiment, reference is made to... Figure 5 and Figure 7 As shown, the glass assembly 100 may further include a third adhesive layer 125, which is connected to the side edge of the electrical functional layer 123 and is located between the first adhesive layer 122 and the second adhesive layer 124 in a first direction. This helps to increase the adhesive area and adhesive force in the edge region, effectively ensuring the integrity of the structure.

[0116] In one embodiment, reference Figure 9 and Figure 10 As shown, it may also include an electrode lead 150. Along the first direction, the electrode lead 150 may be disposed between the first adhesive layer 122 and the third adhesive layer 125, or the electrode lead 150 may be disposed between the third adhesive layer 125 and the second adhesive layer 124.

[0117] On a plane perpendicular to the first direction, the electrical functional layer 123 and the first connection structure 160 are spaced apart. One end of the electrode lead 150 is electrically connected to the electrical functional layer 123, and the other end of the electrode lead 150 is electrically connected to the first connection structure 160.

[0118] The electrode lead 150 is typically a flexible conductive material, such as metal foil (copper foil) or flexible printed current. One end of the electrode lead 150 can be electrically connected to the transparent electrode at the edge of the electrical functional layer 123 by conductive silver paste or welding. The other end of the electrode lead 150 is connected to the electrical connector 130 embedded in the first connection structure 160 by welding or other means.

[0119] By sandwiching the flexible electrode lead 150 between the first adhesive layer 122 and the third adhesive layer 125 or the second adhesive layer 124 and the third adhesive layer 125, it is equivalent to providing a buffer pad for the electrode lead 150, which helps to absorb the thermal expansion and contraction stress, vibration and impact during the manufacturing, installation and use of the glass assembly, and prevents the electrode lead 150 from fatigue fracture due to stress concentration.

[0120] Meanwhile, on a plane perpendicular to the first direction, the electrical functional layer 123 and the first connection structure 160 are spaced apart, so that the electrode lead 150 can have a smooth, horizontally extending transition section. The electrode lead 150 can start from the surface of the electrical functional layer 123, run horizontally for a distance, and then connect to the first connection structure 160. This achieves physical isolation between the functional area and the connection area, avoids mutual interference, and significantly improves the long-term reliability of the electrical connection.

[0121] It should be noted that "a plane perpendicular to the first direction" means that the first direction refers to the thickness direction of the glass assembly 100, and a plane perpendicular to the first direction is a plane parallel to the glass substrate 110.

[0122] In one embodiment, reference Figure 11 As shown, the electrical connector 130 may include a conductive inner core 131, an insulating layer 132, and an encapsulation layer 133; the insulating layer 132 covers the outer periphery of the conductive inner core 131, the encapsulation layer 133 covers the outer periphery of the insulating layer 132, one end of the conductive inner core 131 is electrically connected to the electrical functional layer 123, and the other end of the conductive inner core 131 is configured to be electrically connected to the power supply; the first connection structure 160 covers the outer periphery of the insulating layer 132.

[0123] For example, refer to Figure 12 As shown, the electrical connector 130 can be square in shape; or, refer to... Figure 13 As shown, the electrical connector 130 can be circular; or, the electrical connector 130 can be any other shape. This embodiment does not limit this.

[0124] In this embodiment, the conductive core 131 is the core channel for current transmission and is made of a highly conductive material. For example, the conductive core 131 can be made of copper or a copper alloy. The insulating layer 132 wraps around the outer periphery of the conductive core 131 and is typically made of a flexible polymer. For example, the insulating layer 132 can be made of flexible silicone or polyurethane. Its main function is to prevent current leakage and ensure electrical safety.

[0125] In this embodiment, the encapsulation layer 133, as the outermost protective structure, needs to be made of materials with high mechanical strength, wear resistance, and environmental aging resistance. For example, the material of the encapsulation layer 133 can be a curing adhesive or epoxy resin. Its main function is to protect the internal insulating layer 132 and conductive core 131, reduce friction and compression on the insulating layer 132 and conductive core 131, and extend their service life.

[0126] Therefore, by setting a conductive inner core 131, an insulating layer 132, and an encapsulation layer 133, the combination of the insulating layer 132 and the encapsulation layer 133 provides a double insulation and protective barrier for the conductive inner core 131, enabling it to effectively resist moisture and other conditions in the vehicle interior environment, thereby maximizing the long-term stability of the electrical connector 130 and extending its service life.

[0127] The glass assembly and vehicle provided in this application embodiment form a groove by recessing at least a portion of the side edges of the composite functional layer inward. On the one hand, this recess protects the electrical connector and the first connection structure from direct external impact, solving the problem in related technologies where electrical connectors are easily damaged or detached due to external impact, thus improving the reliability of the electrical connector connection. On the other hand, this design achieves complete concealment of the electrical connector, resulting in a clean and smooth glass appearance and enhancing the product's aesthetics. Furthermore, the interface layout on the side edges provides an intuitive and convenient operating channel for installation and maintenance, simplifying the operation process, improving efficiency, saving maintenance costs and time, and enhancing the user experience.

[0128] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0129] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
