Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle parts technology, and more particularly to a connector, a glass assembly, and a vehicle. Background Technology
[0002] With the development of the automotive industry, automotive windows with functions such as heating, color changing, or transparency adjustment are gradually becoming mainstream. These multi-functional automotive windows typically feature laminated glass, within which electrical components and connectors are installed. These connectors transmit power from the vehicle's internal power source to the electrical components within the window glass. Existing connectors consist of copper foil, a cover layer, an injection-molded block, and wires. The injection-molded block encapsulates and seals the copper foil and wires, which are bonded to the cover layer. However, as the plastic cools and forms the injection-molded block, it shrinks, creating gaps between the injection-molded block and the cover layer and wires. Moisture can seep through these gaps to the connection between the copper foil and the wires, causing connector malfunction and affecting the normal use of the automotive window glass.

Detailed Implementation
[0025] 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 only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0026] Please see Figures 1 to 3 , Figure 1 This is a structural schematic diagram of the vehicle 10000 provided in the embodiments of this application. Figure 2 yes Figure 1 A partial structural schematic diagram of vehicle 10000 is shown. Figure 3 yes Figure 2 The schematic diagram of a partial structure of vehicle 10000 shown is a cross-sectional view after being cut along line AA.
[0027] Vehicle 10000 includes a body 1000, a glass assembly 2000, and an adhesive 3000. The body 1000 may be a sheet metal part manufactured using sheet metal processing. The glass assembly 2000 is mounted on the body 1000. The adhesive 3000 is located between the body 1000 and the glass assembly 2000, and adheres to both to mount the glass assembly 2000 onto the body 1000. The width of the adhesive 3000 is w1. For example, the adhesive 3000 may be a polyurethane adhesive made of polyurethane.
[0028] Please refer to the following: Figure 4 and Figure 5 , Figure 4 yes Figure 2 The diagram shown is a structural schematic of the glass assembly 2000 in the deployed state of vehicle 10000. Figure 5 yes Figure 4 The diagram shows a partial structural schematic of the glass assembly 2000. It should be noted that the glass assembly 2000 being in the unfolded state refers to the state where the connector 200 is not bent relative to the window glass 100.
[0029] Glass assembly 2000 includes window glass 100, connector 200, and sealant 300. Window glass 100 may be laminated glass. Window glass 100 may include an inner glass 110, an outer glass (not shown), and electrical components (not shown). The inner glass 110 is the glass of window glass 100 closest to the interior of vehicle 10000. The outer glass is the glass of window glass 100 closest to the exterior of vehicle 10000. The outer glass and inner glass 110 are spaced apart and opposite each other. Electrical components are installed between the inner glass 110 and the outer glass. Connector 200 may extend from the edge of window glass 100 into the space between the inner glass 110 and the outer glass and be electrically connected to the electrical components; it may also be bent relative to window glass 100 to the side of window glass 100 facing the interior of the vehicle. The sealant 300 is located between the connector 200 and the window glass 100, and connects the connector 200 and the window glass 100. It not only bonds the connector 200 to the window glass 100, but also seals the gap between the window glass 100 and the connector 200, preventing moisture from seeping into the interior of the vehicle 10000 through this gap. The width of the sealant 300 is w2.
[0030] In this embodiment, the sealant 300 and the adhesive 3000 are correspondingly disposed along the thickness direction of the window glass 100. Specifically, the projections of the adhesive 3000 and the sealant 300 on the window glass 100 at least partially overlap along the thickness direction of the window glass 100. Specifically, the width w2 of the sealant 300 is greater than or equal to the width w1 of the adhesive 3000 to ensure that the sealant 300 extends beyond the adhesive 3000, further guaranteeing the sealing between the joint 200 and the window glass 100, and between the glass assembly 2000 and the vehicle body 1000.
[0031] The connector 200 includes a strip conductor 10, a wire 20, an electronic device 30, and a first sealing structure 40. The strip conductor 10 extends from the edge of the window glass 100 between the inner glass 110 and the outer glass, and connects to electrical components within the window glass 100. The strip conductor 10 can also be bent relative to the window glass 100 to the side of the window glass 100 closer to the interior of the vehicle 10000. The strip conductor 10 is flexible and adaptable to bend and adjust as needed during assembly with the window glass 100. The wire 20, electronic device 30, and first sealing structure 40 are all located on the side of the window glass 100 closer to the interior of the vehicle 10000. The wire 20 is electrically connected between the strip conductor 10 and the electronic device 30. The wire 20 transmits signals from the electronic device 30 to the electrical components via the strip conductor 10, allowing the electrical components to operate according to the signals. For example, when the electrical component is a heating element, it can heat the window glass 100 to perform defrosting or defogging operations. The first sealing structure 40 can seal the connection between the strip conductor 10 and the wire 20, sealing the connection and preventing gaps from forming between the strip conductor 10 and the wire 20. This effectively prevents moisture from seeping into the gap between the strip conductor 10 and the wire 20, which could cause the connector 200 to malfunction.
[0032] The strip conductor 10 includes a conductor 11, a covering layer 12, and an adhesive 13. In this embodiment, the conductor 11 may be a copper foil made of copper. The conductor 11 includes a first connecting portion 111, a second connecting portion 112, and an intermediate connecting portion 113. The first connecting portion 111 is located at one end of the conductor 11. The first connecting portion 111 can extend between the inner glass 110 and the outer glass and is electrically connected to an electrical component. The second connecting portion 112 is located at the other end of the conductor 11 and is used to connect to the wire 20. The second connecting portion 112 is located on the side of the window glass 100 closer to the interior of the vehicle 10000. The intermediate connecting portion 113 connects the first connecting portion 111 and the second connecting portion 112 and can be bent relative to the window glass 100 to the side of the window glass 100 closer to the interior of the vehicle 10000. The cover layer 12 covers the intermediate connecting portion 113 and can be bent together with the intermediate connecting portion 113 relative to the side of the window glass 100 closer to the interior of the vehicle 100. The cover layer 12 serves to protect and seal the intermediate connecting portion 113. The portion of the intermediate connecting portion 113 near the first connecting portion 111 and the portion of the cover layer 12 near the first connecting portion 111 can both extend between the inner glass 110 and the outer glass to increase the contact area between the joint 200 and the window glass 100, ensuring reliable connection between the joint 200 and the window glass 100. Adhesive 13 is located between the intermediate connecting portion 113 and the cover layer 12, and is bonded between the intermediate connecting portion 113 and the cover layer 12, so that the intermediate connecting portion 113 and the cover layer 12 are bonded together by the adhesive 13.
[0033] In this embodiment, the adhesive 3000 is located between the cover layer 12 and the vehicle body 1000, and connects the cover layer 12 and the vehicle body 1000. At this time, the sealant 300, the strip conductor 10, and the adhesive 3000 together constitute the second sealing structure between the window glass 100 and the vehicle body 1000, effectively preventing moisture from entering the interior of the vehicle 10000 through the gaps between the strip conductor 10 and the window glass 100 and between the strip conductor 10 and the vehicle body 1000, thus avoiding the problem of water leakage during use.
[0034] The conductor 20 includes a conductive core 21 and an insulating layer 22. In this embodiment, the conductive core 21 can be a copper core made of copper. The conductive core 21 may include a connecting end 211 and a conductive body 212. The connecting end 211 is located at one end of the conductive core 21 near the strip conductor 10, and is located on one side in the direction of the second connecting portion 112, and is electrically connected to the second connecting portion 112. For example, the connecting end 211 is located on one side in the thickness direction of the second connecting portion 112, and is spaced apart from both the covering layer 12 and the adhesive 13. The connecting end 211 is in direct contact with the second connecting portion 112. Specifically, the connecting end 211 can be directly welded to the second connecting portion 112 using pressure welding or ultrasonic welding processes. Compared to traditional solder welding processes, pressure welding or ultrasonic welding processes melt and fuse the surface of the connecting end 211 and the second connecting portion 112 together, achieving the purpose of direct connection. During the welding process of the connecting end 211 and the second connecting portion 112, the portion of the connecting end 211 near the second connecting portion 112 is fused together with the portion of the second connecting portion 112 near the connecting end 211 to form a fused portion a, thereby achieving an electrical connection between the strip conductor 10 and the wire 20. It is understood that the conductor 11 of the strip conductor 10 is directly welded to the conductive core 21 of the wire 20 without the need for solder, effectively avoiding the problems of increased resistance at the connection point between the strip conductor 10 and the wire 20, and damage to the insulation layer 22 of the wire 20. The conductive body 212 is connected to the side of the conductive core 21 away from the intermediate connecting portion 113 and is electrically connected to the electronic device 30. The insulation layer 22 covers the conductive body 212, which not only protects the conductive body 212 but also provides insulation.
[0035] The first sealing structure 40 covers the second connecting portion 112, the connecting end 211, the portion of the covering layer 12 near the second connecting portion 112, and the portion of the insulating layer 22 facing the connecting end 211, to seal the connection between the strip conductor 10 and the wire 20, preventing moisture from seeping into the connection between the strip conductor 10 and the wire 20 and causing the connector 200 to malfunction, thus ensuring the reliability of the connector 200. The first sealing structure 40 includes a connecting adhesive 41 and a plastic sealant 42. The connecting adhesive 41 is located on the innermost side of the first sealing structure 40 and covers the second connecting portion 112, the connecting end 211, the portion of the covering layer near the second connecting portion 112, and the portion of the insulating layer 22 facing the connecting end 211. The plastic sealant 42 wraps around the connecting adhesive 41.
[0036] In this embodiment, the plastic seal 42 includes a plastic protective sleeve 421 and a plastic adhesive 422. The plastic adhesive 422 wraps around the connecting adhesive 41. The plastic protective sleeve 421 wraps around the plastic adhesive 422. The plastic protective sleeve 421 serves to shape and protect the plastic adhesive 422. After being heated to a high temperature, the plastic protective sleeve 421 and the plastic adhesive 422 soften and can tightly adhere to the connecting adhesive 41, thereby allowing the plastic seal 42 to conform to the second connecting portion 112, the connecting end 211, the portion of the covering layer 12 near the second connecting portion 112, and the portion of the insulating layer 22 facing the connecting end 211. The plastic protective sleeve 421 and the plastic adhesive 422 play a major sealing role in the first sealing structure 40.
[0037] The connecting adhesive 41 connects the plastic adhesive 422 to the connecting end 211, the plastic adhesive 422 to the second connecting part 112, the plastic adhesive 422 to the portion of the covering layer 12 near the second connecting part 112, and the plastic adhesive 422 to the portion of the insulating layer 22 near the connecting end 211. This prevents gaps from forming between the plastic adhesive 422 and the strip conductor 10 and the wire 20 during cooling and shrinkage, effectively preventing moisture from seeping into the gap between the strip conductor 10 and the wire 20, effectively avoiding joint 200 failure, and playing an auxiliary sealing role. In addition, the dimensions of the strip conductor 10 and the wire 20 are not fixed. Since the plastic protective sleeve 421 and the plastic adhesive 422 are plastic and can expand and contract after heating, it is convenient to combine wires 20 of different diameters with strip conductors 10 of different sizes. This makes the first sealing structure 40 versatile and reduces the increased manufacturing cost of the first sealing structure 40 due to the combination of wires 20 of different diameters with strip conductors 10 of different sizes.
[0038] In this embodiment, the first sealing structure 40 covers the second connecting portion 112, the connecting end 211, the portion of the covering layer 12 near the second connecting portion 112, and the portion of the insulating layer 22 facing the connecting end 211. This effectively seals the connection between the strip conductor 10 and the wire 20, preventing moisture from seeping into the connection and causing the connector 200 to malfunction. Furthermore, the sealant 300 and adhesive 3000 fix the strip conductor 10 between the window glass 100 and the vehicle body 1000, sealing the strip conductor 10 with the window glass 100 and the vehicle body 1000. This effectively seals the gaps between the strip conductor 10 and the window glass 100 and the vehicle body 1000, preventing moisture from entering the vehicle 10000 through these gaps and avoiding water leakage after the glass assembly 2000 is installed.
[0039] The above descriptions are merely optional embodiments of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the core ideas of this application and are not intended to limit the patent scope of this application. At the same time, for those skilled in the art, equivalent structural transformations made based on the inventive concept of this application using the specification and drawings of this application, or direct / indirect applications in other related technical fields, are all included within the patent protection scope of this application.
