Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a conductive connection assembly, a glass assembly, and a vehicle. Background Technology

[0002] While driving, drivers need to observe the traffic conditions on the road to avoid traffic problems. To ensure drivers can still see clearly even when the glass is fogged up or frosted, silver paste heating wires and a conductive layer are currently printed on the vehicle's glass. Conductive connectors are soldered onto the conductive layer to connect to a power source, allowing electrical energy to be conducted to the heating wires. This energizes the heating wires, raising the glass temperature to defrost and clear away fog, ensuring optimal visibility.

[0003] Because the materials welded to the conductive layer have a high melting point, the temperature at the welded part of the glass will be higher than the temperature of other parts of the glass during the process of welding the conductive connector to the conductive layer. Furthermore, since glass is a poor conductor of heat, its own thermal expansion and contraction characteristics will affect the stress of the glass when welding the conductive connector, leading to cracks or breakage at the welded position. Moreover, microcracks on the glass are difficult to detect during the production process and are more likely to be discovered when the user powers on the heating wire. This will significantly increase the vehicle's maintenance costs and reduce user satisfaction. Utility Model Content

[0005] The first aspect of this application provides a conductive connection assembly, characterized in that it comprises:

[0012] In some possible embodiments of the first aspect, the conductive connection assembly further includes an adhesive element disposed on a third surface of the metal layer and located in a different region from the first weld layer on the third surface of the metal layer, the metal layer being connected to the conductive layer via the adhesive element.

[0013] In some possible embodiments of the first aspect, the adhesive element is disposed around the first weld layer.

[0014] In some possible embodiments of the first aspect, the adhesive component has a thickness of 0.1-0.5 mm in the first direction of the first weld layer toward the conductive connector, and the thickness of the first weld layer in the first direction is 0.3-0.6 mm, wherein the thickness of the first weld layer is greater than the thickness of the adhesive component.

[0015] In some possible embodiments of the first aspect, the conductive connection assembly further includes a second welding layer disposed between the conductive connector and a second surface of the metal layer, wherein the conductive connector is welded to the second surface of the metal layer via the second welding layer, and wherein the melting point of the second welding layer is greater than the ambient temperature at which the first welding layer is welded to the conductive layer.

[0016] In some possible embodiments of the first aspect, the number of the second weld layers is at least one, and the first weld layer is disposed on the third surface of the metal layer corresponding to the position of the second weld layer.

[0017] In some possible embodiments of the first aspect, the melting point of the first weld layer is 95-130°C.

[0018] A second aspect of this application provides a glass assembly, comprising:

[0019] Glass;

[0020] A conductive layer is disposed on the glass;

[0021] A heating wire is disposed on the glass and connected to the conductive layer so as to generate heat when the conductive layer receives electrical energy;

[0022] The conductive connection components as described above.

[0023] In some possible embodiments of the second aspect, the glass includes a first glass, a second glass, and an adhesive layer disposed between the first glass and the second glass, the first glass and the second glass being connected by the adhesive layer, and the conductive layer and the heating wire being disposed on the surface of the first glass away from the second glass, or the conductive layer and the heating wire being disposed on the surface of the second glass away from the first glass.

[0028] This application provides a conductive connection assembly, a glass assembly, and a vehicle. The conductive connection assembly includes a conductive connector and a first welding layer, the first welding layer being disposed on a first side of the conductive connector, wherein the melting point of the first welding layer is less than or equal to 130°C, wherein the conductive connector is used to connect to a power source and to weld to a conductive layer on a glass via the first welding layer, so as to electrically connect with the conductive layer at least through the first welding layer, thereby providing electrical energy to the conductive layer. This application involves welding the conductive connection component onto the conductive layer in an autoclave. Since the melting point of the first weld layer is lower than or equal to 130°C, the welding environment temperature of the autoclave is higher than the melting point of the first weld layer. This allows the first weld layer to be molten during the welding process of the conductive connection component to the conductive layer, and its temperature is affected by the welding environment temperature. Since the temperature of each part of the glass in the autoclave is essentially equal to the welding environment temperature, the temperature of each part of the glass will be the same during welding, eliminating temperature differences and reducing stress on the glass during welding. This prevents cracking or breakage at the weld position, thus eliminating cracks during glass production, fundamentally reducing maintenance costs, and improving user satisfaction. Furthermore, the first weld layer, with a melting point lower than or equal to 130°C, can completely melt in the autoclave, allowing for a more secure connection between the conductive connection component and the conductive layer after removal from the autoclave, improving connection stability and further reducing subsequent maintenance costs.

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely one embodiment of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] In the description of the embodiments of this application, it should be understood that the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. The term "connection" in this application, unless otherwise specified, primarily refers to a physical structural connection; however, if specified, it may also include direct or indirect connections. The terms "first" and "second" in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0052] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a conductive connection assembly 100 according to an embodiment of this application. The conductive connection assembly 100 includes a conductive connector 1 and a first welding layer 2. The first welding layer 2 is disposed on a first side 11 of the conductive connector 1. (See also...) Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the conductive connection component 100 installed on the conductive layer 400 in one embodiment of this application. Figure 3 for Figure 2 In the enlarged view at point A, the melting point of the first weld layer 2 is less than or equal to 130°C. The conductive connector 1 is used to connect to a power source and to weld to a conductive layer 400 on a glass 300 via the first weld layer 2, so as to provide electrical energy to the conductive layer 400 at least through the first weld layer 2.

[0053] Therefore, the conductive connection component 100 is welded to the conductive layer 400 in the autoclave. Since the melting point of the first welding layer 2 is lower than or equal to 130°C, the welding environment temperature of the autoclave must be higher than the melting point of the first welding layer 2. This allows the first welding layer 2 to be molten during the welding of the conductive connection component 1 to the conductive layer 400 via the first welding layer 2, and its temperature will be affected by the welding environment temperature, becoming the welding environment temperature. The temperature of each part of the glass 300 in the autoclave is also basically equal to the welding environment temperature. Therefore, the temperature of each part of the glass 300 during the welding process is... Since the temperature difference caused by welding is the same, the stress on the glass 300 during welding is reduced, thus preventing cracks or breakage at the weld position. This eliminates the possibility of cracks in the glass 300 during production, fundamentally reducing maintenance costs and improving user satisfaction. Furthermore, the first weld layer 2, with a melting point of 130°C or lower, can completely melt in the autoclave. After leaving the autoclave, the solid first weld layer 2 provides a more secure connection between the conductive connection component 100 and the conductive layer 400, improving the stability of the connection and further reducing subsequent maintenance costs.

[0054] Specifically, the first welding layer 2 has been pre-welded to the first side 11 of the conductive connector 1. The conductive connector 100 is connected to the conductive layer 400 through the first welding layer 2. Since the melting point of the first welding layer 2 is lower than the welding environment temperature, the first welding layer 2 will melt into a liquid state in this environment. At this time, the conductive connector 1 is connected to the conductive layer 400 through the liquid first welding layer 2. After the glass 300 and the conductive connector 100 are removed from the autoclave, the first solder layer will solidify into a solid state because its melting point is higher than the subsequent environment temperature. At this time, the conductive connector 1 is directly fixedly connected to the conductive layer 400 through the solid first welding layer 2.

[0055] Furthermore, by limiting the melting point of the first welding layer 2, the first welding layer 2 can be completely melted in the autoclave, and thus, after leaving the autoclave, the conductive connection component 100 and the conductive layer 400 can be more firmly fixedly connected by the first welding layer 2 that has become solid.

[0056] As mentioned above, since the first welding layer 2 only needs to change its state according to the ambient temperature, the conductive connector 1 can be welded to the conductive layer 400 on the glass 300 through the first welding layer 2. There is no need to manually weld the conductive connector 1 to the conductive layer 400 through the first welding layer 2. The automatic welding of the conductive connector 1 and the conductive connection assembly 100 can be realized, which optimizes the welding process, improves welding efficiency and production capacity, and also reduces labor costs and saves production time.

[0057] In some embodiments, the conductive connector 1 is made of copper or stainless steel. Since copper has better thermal conductivity and electrical conductivity than stainless steel, copper is often chosen to make the conductive connector 1, which can prevent the conductive connector 1 from getting too hot when it is energized.

[0058] The material of the first welding layer 2 is leaded solder or lead-free solder. For environmental protection requirements, low-melting-point lead-free solder is preferred as the material of the first welding layer 2. More specifically, since indium has good ductility and low melting point characteristics, indium-based lead-free solder is often used as the material of the first welding layer 2.

[0059] like Figure 1 As shown, the protruding plate-like structure at the top of the conductive connector 1 is used to insert into a junction box to form a plug-in connection, and then connect to the power supply through the wires of the junction box. The junction box is provided with two opposing elastic limiting members. When the protruding plate-like structure is inserted into the junction box, the two elastic limiting members will be pressured and move away from each other, and then move closer to each other to insert into the round hole on the protruding plate-like structure of the conductive connector 1, thereby fixing and limiting the conductive connector 1.

[0060] In some embodiments, the conductive connection assembly 100 further includes an adhesive component 3, which is disposed on the first side 11 of the conductive connection 1 and is located in a different area on the first side 11 of the conductive connection 1 from the first welding layer 2. The conductive connection 1 is also connected to the conductive layer 400 through the adhesive component 3.

[0061] Therefore, the conductive connector 1 can be pre-fixed to the conductive layer 400 by the adhesive 3, making the connection between the conductive connector 1 and the conductive layer 400 more stable, improving the stability of the connection, and preventing the conductive connector 1 from falling off the conductive layer 400 during the connection process.

[0062] Please see Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the structure of the conductive connection component 100 in another embodiment of this application. Figure 5 for Figure 4A schematic diagram of the conductive connection component 100 in another direction is shown. In some embodiments, the conductive connection component 100 further includes a metal layer 4 disposed on the first side 11 of the conductive connector 1 and located between the conductive connector 1 and the first welding layer 2. The first surface of the conductive connector 1 is adhered and fixedly connected to the second surface 41 of the metal layer 4, and the first welding layer 2 is disposed on the third surface 42 of the metal layer 4 opposite to the second surface 41. (See also...) Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the conductive connection component 100 mounted on the conductive layer 400 in another embodiment of this application. Figure 7 for Figure 6 Enlarged view at point B. The conductive connector 1 is welded to the conductive layer 400 on the glass 300 via a first welding layer 2 disposed on the third surface 42 of the metal layer 4. The conductive connector 1 is also electrically connected to the conductive layer 400 via the metal layer 4 and the first welding layer 2 in sequence.

[0063] As mentioned above, in addition to the reasons for the cracks or breaks at the welding position of the glass 300, the large difference in the coefficient of thermal expansion and thermal conductivity between the material of the conductive connector 1 and the material of the glass 300 causes the conductive connector 1 to exert stress on the surface of the glass 300 when it cools and contracts after welding, which in turn causes the glass 300 to weaken or form microcracks.

[0064] By adding the metal layer 4 as a connection medium between the conductive connectors 1, since the metal layer 4 is a sheet-like layered structure, the thickness of the metal layer 4 must be relatively thin. Therefore, after welding, the stress generated by the metal layer 4 on the surface of the glass 300 is also relatively small, thereby reducing stress weakening of the glass 300 and preventing microcracks from appearing in the glass 300.

[0065] In some embodiments, the metal layer 4 is a copper foil with a thickness of less than 0.2 mm. The copper foil can be made of brass or pure copper. Since pure copper has better conductivity and ductility, it is preferred to use pure copper as the material for making the copper foil.

[0066] In some embodiments, such as Figure 4 and Figure 5As shown, the conductive connection assembly 100 further includes an insulating film 5, which is attached to the second surface 41 and / or the third surface 42 of the metal layer 4. The insulating film 5 has an opening 51. When the insulating film 5 is attached to the second surface 41 of the metal layer 4, the conductive connector 1 is electrically connected to the portion of the second surface 41 of the metal layer 4 exposed at the opening 51, and / or, when the insulating film 5 is attached to the third surface 42 of the metal layer 4, the first welding layer 2 is electrically connected to the portion of the third surface 42 of the metal layer 4 exposed at the opening 51.

[0067] Therefore, the presence of the insulating film 5 can prevent other parts of the metal layer 4 from contacting the conductive connector 1 and / or the conductive layer 400, thereby enhancing the electrical isolation of other parts, preventing the oxidation of the metal layer 4, and enhancing the stability of the conductive connector 1 connecting the conductive layer 400 through the metal layer 4 and the first welding layer 2.

[0068] In some embodiments, the insulating film 5 may be a PI film. Compared with other types of insulating films 5, the PI film has better heat resistance and electrical insulation, and can therefore perform better in the high-temperature environment of the autoclave.

[0069] In some embodiments, the second surface 41 and the third surface 42 of the metal layer 4 are electroplated, typically with silver or tin. Tin plating is preferred because it is more economical and has better solderability. After electroplating, an insulating film 5 is attached to the second surface 41 and / or the third surface 42 of the metal layer 4.

[0070] In some embodiments, the conductive connector 1 can also be fixedly connected to the metal layer 4 by spot welding.

[0071] In some embodiments, such as Figure 5 As shown, the adhesive component 3 is disposed on the third surface 42 of the metal layer 4, and is located in a different area on the third surface 42 of the metal layer 4 from the first welding layer 2. The metal layer 4 is connected to the conductive layer 400 through the adhesive component 3.

[0072] Therefore, the conductive connection component 100 can be pre-fixed to the conductive layer 400 by the adhesive component 3, making the connection between the metal layer 4 and the conductive layer 400 more stable, improving the stability of the connection, and preventing the conductive connection component 100 from falling off the conductive layer 400 during the connection process.

[0073] The adhesive component 3 can be PU adhesive or tape.

[0074] In some embodiments, such as Figure 5As shown, the adhesive component 3 is disposed around the first welding layer 2.

[0075] Therefore, by surrounding the first welding layer 2 with the adhesive component 3, the first welding layer 2 can be prevented from flowing out when it is in a liquid state, thereby avoiding contamination of the glass 300 by the first welding layer 2. Furthermore, the first welding layer 2 can be located in the same area at least most of the time, increasing the strength of the connection between the conductive connection component 100 and the conductive layer 400.

[0076] In some embodiments, the adhesive component 3 is arranged in a U-shaped closed structure around the first welding layer 2, with the first welding layer 2 located in the middle region of the adhesive component 3.

[0077] In some embodiments, as described above, when the insulating film 5 is attached to the third surface 42 of the metal layer 4 and the insulating film 5 has an opening 51, the adhesive 3 can be adhered to the periphery of the opening 51 of the insulating film 5 on the third surface 42, that is, the adhesive 3 is disposed on the insulating film 5. The insulating film 5 has good adhesion, which makes it easy for the adhesive 3 to be adhered to the insulating film 5. The first welding layer 2 is disposed on the metal layer 4 exposed by the opening 51, so as to be located in the middle area of ​​the adhesive 3.

[0078] Please see Figure 8 and Figure 9 , Figure 8 for Figure 4 Top view of conductive connection component 100 in the middle. Figure 9 for Figure 8 Cross-sectional view at CC. In some embodiments, the thickness of the adhesive component 3 in the first direction 6 of the first weld layer 2 toward the conductive connector 1 is 0.1-0.5 mm, and the thickness of the first weld layer 2 in the first direction 6 is 0.3-0.6 mm, wherein the thickness of the first weld layer 2 is greater than the thickness of the adhesive component 3.

[0079] Therefore, the thickness of the first welding layer 2 is greater than the thickness of the adhesive 3, which facilitates better dispersion of the first welding layer 2 on the surface of the metal layer 4 when it is in a liquid state, thereby increasing the area of ​​the metal layer 4 connected to the conductive layer 400 and improving the stability of the connection between the metal layer 4 and the conductive layer 400.

[0080] In some embodiments, such as Figure 4As shown, the conductive connection assembly 100 further includes a second welding layer 7, which is disposed between the conductive connector 1 and the second surface 41 of the metal layer 4. The conductive connector 1 is welded to the second surface 41 of the metal layer 4 through the second welding layer 7. The melting point of the second welding layer 7 is greater than the ambient temperature when the first welding layer 2 is welded to the conductive layer 400.

[0081] Thus, the conductive connector 1 is welded to the second surface 41 of the metal layer 4 through the second welding layer 7, which can increase the stability of the connection between the conductive connector 1 and the metal layer 4. Furthermore, the melting point of the second welding layer 7 is higher than the welding ambient temperature, so that the second welding layer 7 remains solid in the autoclave. This prevents the second welding layer 7 from melting into a liquid state during the welding of the conductive connector 100 to the conductive layer 400, which would cause the conductive connector 1 to detach from the metal layer 4.

[0082] In some embodiments, the conductive connector 1 can also be fixed to the second surface 41 of the metal layer 4 by riveting.

[0083] Please see Figures 10-13 , Figure 10 This is a schematic diagram of the structure of the conductive connection component 100 in another embodiment of this application. Figure 11 for Figure 10 A schematic diagram of the conductive connection component 100 in another direction. Figure 12 This is a schematic diagram of the structure of the conductive connection component 100 in another embodiment of this application. Figure 13 for Figure 12 The conductive connection component 100 is shown in a schematic diagram from another direction. In some embodiments, the number of second welding layers 7 is at least one, and the first welding layer 2 is disposed on the third surface 42 of the metal layer 4 at a position corresponding to the second welding layer 7.

[0084] Therefore, the conductive connector 1 can be fixedly connected to the metal layer 4 through multiple second welding layers 7 to increase the strength of the connection between the conductive connector 1 and the metal layer 4. Furthermore, the first welding layer 2 is provided corresponding to the second welding layer 7, including the number of the first welding layer 2 corresponding to the number of the second welding layer 7. When there are multiple second welding layers 7, there are also multiple first welding layers 2. Then, the conductive connection assembly 100 can be connected to the conductive layer 400 through the multiple first welding layers 2 to enhance the strength of the connection between the conductive connection assembly 100 and the conductive layer 400. In addition, the first welding layer 2 is also provided on the third surface 42 of the metal layer 4 corresponding to the position of the second welding layer 7, which allows the heat absorbed by the conductive connector 1 to be transferred to the first welding layer 2 more quickly, so that the first welding layer 2 melts into a liquid state more quickly.

[0085] The first welding layer 2 and the second welding layer 7 are multiple in number, which can disperse the current during the conduction process and prevent the conductive connector 1 from getting too hot after conduction. In principle, the number of the first welding layer 2 and the number of the second welding layer 7 are the same to ensure the balance of conduction of the first welding layer 2 and the second welding layer 7.

[0086] like Figure 4 , Figure 10 and Figure 12 As shown, the shape and structure of the conductive connector 1 can be set according to actual needs, and the conductive connector 1 with different structures must form a plug-in connection with the junction box before it can be connected to the power supply.

[0087] In some embodiments, the melting point of the first weld layer 2 is 95-130°C.

[0088] Therefore, by limiting the specific values ​​of the welding environment temperature and the melting point of the first welding layer 2, the first welding layer 2 can be completely melted in the autoclave. After leaving the autoclave, it can more firmly fix the conductive connection component 100 and the conductive layer 400 through the solidified first welding layer 2. Furthermore, the melting point of the first welding layer 2 should not be too low to prevent the first welding layer 2 from becoming liquid when using the glass 300 under direct sunlight.

[0089] In some embodiments, when the welding ambient temperature is 145°C, the melting point of the first weld layer 2 is 95-130°C.

[0090] In some embodiments, the pressure inside the autoclave is 8-12 Pa.

[0091] Therefore, air pressure can be applied to the conductive connection assembly 100 to enhance the connection between the conductive connection assembly 100 and the conductive layer 400 through the first welding layer 2.

[0092] Since there is a certain pressure inside the autoclave, the melting point of the first weld layer 2 will rise inside the autoclave. By setting the difference between the welding environment temperature and the melting point of the first weld layer 2 within a preset range, the melting point of the first weld layer 2 will still be lower than the welding environment temperature after rising, so that it can melt into a liquid state. This avoids the situation where the melting point of the first weld layer 2 rises to be equal to or greater than the welding environment temperature, thus preventing it from melting into a liquid state in the autoclave.

[0093] In some embodiments, the first weld layer 2 is sheet-like, and the shape of the first weld layer 2 is square or circular. Since the circular first weld layer 2 can absorb heat more evenly, the shape of most first weld layers 2 is set to be circular.

[0094] like Figure 2 As shown, the glass assembly 200 includes glass 300, conductive layer 400, heating wire 500 and conductive connection assembly 100. The conductive layer 400 is disposed on the glass 300, the heating wire 500 is disposed on the glass 300, and the heating wire 500 is connected to the conductive layer 400 to generate heat when the conductive layer 400 receives electrical energy.

[0095] Therefore, the welding of the conductive connection component 100 will not cause the welded position of the glass 300 to crack or have fissures. It will reduce the stress impact of the conductive connector 1 on the glass 300 during the welding process, and thus will not cause the welded position of the glass 300 to crack or have fissures. The glass 300 will not have fissures during the production process, which will fundamentally reduce maintenance costs and improve user satisfaction.

[0096] The heating wire 500 and the conductive layer 400 are printed on the surface of the glass 300. There are two conductive layers 400, which are disposed opposite each other on the glass 300 and connected to the two ends of the heating wire 500. A conductive connection component 100 is welded to each conductive layer 400. One conductive connection component 100 is connected to the positive terminal of the power supply, and the other conductive connection component 100 is connected to the negative terminal of the power supply. This forms an electrical circuit with the conductive connection component 100, the conductive layer 400, and the heating wire 500, so that the heating wire 500 is energized and heated to achieve the function of defrosting and defogging.

[0097] Please see Figure 14 and Figure 15 , Figure 14 This is a side view of the glass assembly 200 in one embodiment of this application. Figure 15 This is a side view of a glass assembly 200 according to another embodiment of this application. In some embodiments, the glass 300 includes a first glass 301, a second glass 302, and an adhesive layer 303. The adhesive layer 303 is disposed between the first glass 301 and the second glass 302, and the first glass 301 and the second glass 302 are connected by the adhesive layer 303. The conductive layer 400 and the heating wire 500 are disposed on the surface of the first glass 301 away from the second glass 302, or the conductive layer 400 and the heating wire 500 are disposed on the surface of the second glass 302 away from the first glass 301.

[0098] Currently, the commonly used vehicle glass 300 is tempered glass (thickness of 3.5mm-5mm) or laminated glass (the thickness of the first glass 301 and the second glass 302 is 2.1mm). Since tempered glass and laminated glass with a thicker overall thickness have better surface stress, the conductive connector 1 can be directly welded to the conductive layer 400 of the glass 300. Neither of these two types of glass 300 will have welding cracking problems.

[0099] As passengers increasingly prioritize driving and riding comfort, more and more high-end models are adopting laminated glass. Compared to other types of glass, laminated glass offers better sound insulation. Furthermore, when the first glass 301 and / or the second glass 302 in the aforementioned glass 300 shatter, the adhesive layer 303 can hold the glass fragments together, thereby enhancing safety.

[0100] However, due to the relatively heavy weight of laminated glass (the thickness of the first glass 301 and the second glass 302 is 2.1 mm), thinner laminated glass (the thickness of the first glass 301 and the second glass 302 is less than or equal to 1.6 mm) has been adopted to meet the requirements of weight reduction and energy saving. Specifically, when the first glass 301 is closer to the vehicle interior than the second glass 302, the conductive layer 400 and the heating wire 500 are disposed on the surface of the first glass 301 away from the second glass 302; conversely, when the second glass 302 is closer to the vehicle interior than the first glass 301, the conductive layer 400 and the heating wire 500 are disposed on the surface of the second glass 302 away from the first glass 301.

[0101] However, since glass 300 with a thickness of less than or equal to 1.6 mm has poor strength, it is more prone to cracking when welding the conductive connector 1. Based on the aforementioned welding method and the structure of the conductive connector 100, the welding of the conductive connector 100 of the glass assembly 200 will not cause cracks or fissures at the welding position of the glass 300. This reduces the stress on the glass 300 during the welding process, thus preventing cracks or fissures at the welding position. As a result, the glass 300 will not crack during the production process, fundamentally reducing maintenance costs and improving user satisfaction.

[0102] In another embodiment, the thicknesses of the first glass 301 and the second glass 302 may also be 1.8 mm and 2.0 mm, respectively.

[0103] In some embodiments, the adhesive layer 303 may be a film made of polyvinyl butyral (PVB) resin, or it may be made of other adhesive materials. The adhesive layer 303 tightly bonds the first glass 301 and the second glass 302, thereby increasing the strength of the glass 300. In addition, when the glass 300 breaks, the fragments will be held in place by the adhesive layer 303 and will not fall off rapidly, thus reducing the occurrence of accidents.

[0104] When the first glass 301, the second glass 302, and the adhesive layer 303 are laminated, they need to be placed in an autoclave (145°C, 10 Pa) for 2 hours. The conductive connection component 100 is then welded inside the autoclave to reduce the stress on the glass 300 during the welding process, as mentioned above.

[0105] In some embodiments, the glass assembly 200 further includes a shielding layer 600 disposed on the surface of the first glass 301, and / or, the shielding layer 600 disposed on the surface of the second glass 302.

[0106] Therefore, by setting the shielding layer 600, the conductive layer 400 can be prevented from being seen from outside the vehicle after the glass assembly 200 is installed, thus enhancing the aesthetics.

[0107] Specifically, such as Figure 14 and Figure 15 As shown, when the conductive connection assembly 100 is welded to the second glass 302, it can be as follows: Figure 14 As shown, a shielding layer 600 (which can be ink) is first printed on the second glass 302, and then a conductive layer 400 is printed on the shielding layer 600, or as shown in the figure. Figure 15As shown, a shielding layer 600 is printed on the side of the first glass 301 near the second glass 302 to prevent the conductive layer 400 from being seen from outside the vehicle.

[0108] Please see Figure 16 , Figure 16 This is a schematic block diagram of a vehicle 700 according to an embodiment of this application. The vehicle 700 includes a frame 800 and a glass assembly 200, the glass assembly 200 being mounted on the frame 800.

[0109] In the existing technology, the weakening of the strength of the glass 300 during the welding of the conductive connector 1 is a long-standing issue. Furthermore, during the assembly of the glass 300, automakers randomly tap its outer surface to ensure it remains flat with the vehicle body. This random tapping operation greatly increases the probability of hitting the area where the conductive connector 1 is welded to the glass 300. Since the stress at the welded area has already been weakened during the welding process, when the glass 300 is struck, it is prone to cracking or developing micro-cracks at the welded area, thus significantly affecting the heating function of the glass assembly 200.

[0110] Based on the aforementioned welding method and the structure of the conductive connection component 100, the welding of the conductive connection component 100 of the glass assembly 200 will not cause the welded position of the glass 300 to crack or have fissures. This will reduce the stress impact on the glass 300 during the welding process, thus preventing the welded position of the glass 300 from cracking or having fissures. The glass 300 will not have fissures during the production process, fundamentally reducing maintenance costs and improving user satisfaction.

[0111] In some embodiments, the vehicle 700 includes, but is not limited to, sedans, buses, trucks, tractors, special-purpose vehicles, and special vehicles. The glass 300 may be the windshield, rear windshield, front door glass, rear door glass, and sunroof of the vehicle 700.

[0112] As mentioned above, the power source connected to the conductive connector 1 can be the power source within the vehicle 700.

[0113] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
