[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0026] An embodiment of the present application provides a heated glass.

[0027] As Figures 1 to 4 shown, the heated glass includes a heating wiring harness 4, a glass component 3, and a wire harness connection structure.

[0028] Among them, the wire harness connection structure includes a first connection component 1 and a second connection component 2. The first connection component 1 includes a mounting plate 11, a connecting convex column 12, and a copper foil wire harness 13. One end of the mounting plate 11 is connected to the copper foil wire harness 13, and a connecting convex column 12 is arranged on the plate surface of the mounting plate 11. The copper foil wire harness 13 is used to connect the heating wiring harness 4 of the heated glass; the second connection component 2 includes a body wire harness 22 and a ring terminal 21. The body wire harness 22 is used to connect the vehicle body, and the ring terminal 21 is arranged at the end of the body wire harness 22 away from the body. The ring terminal 21 is used to be sleeved on the connecting convex column 12 so that the heating wiring harness 4 forms a closed loop with the vehicle body. The glass component 3 includes an outer layer glass 31, an interlayer 32, and an inner layer glass 33 which are stacked. The copper foil wire harness 13 is connected to the interlayer 32, and the mounting plate 11 is connected to the inner layer glass 33.

[0029] Please further refer to Figures 1 to 3, the glass assembly 3 includes an outer layer glass 31, an interlayer 32, and an inner layer glass 33 arranged in sequence from the outside of the vehicle to the inside of the vehicle. Among them, the heating wire harness 4 is arranged between the outer layer glass 31 and the inner layer glass 33 and is connected to the interlayer 32, that is, the heating wire harness 4 is arranged between the outer layer glass 31 and the interlayer 32, or the heating wire harness 4 is arranged between the inner layer glass 33 and the interlayer 32. The first connection assembly 1 includes a mounting plate 11, a connecting stud 12, and a copper foil wire harness 13. The copper foil wire harness 13 is arranged between the inner layer glass 33 and the outer layer glass 31. One end of the copper foil wire harness 13 is connected to the heating wire harness 4, and the other end is connected to the mounting plate 11. The connecting stud 12 is arranged on the mounting plate 11. The annular terminal 21 of the second connection assembly 2 is sleeved on the connecting stud 12, and a closed circuit can be formed between the heating wire harness 4 and the vehicle body through the vehicle body wire harness 22, so that the heating wire harness 4 can operate normally.

[0030] In the embodiment of the present application, the first connection assembly 1 and the second connection assembly 2 are used to form a closed circuit of the heating wire harness 4. Compared with the prior art method of using a pluggable connection terminal for circuit connection, the pluggable connection terminal requires an additional fixing structure to be fixed on the glass assembly 3. In the embodiment of the present application, the mounting plate 11 of the first connection assembly 1 is a simple plate-like structure, and the mounting plate 11 can be fixed by means such as bonding without additional structures, without the need for an additional layout space for the fixing structure. In addition, the connection method of the first connection assembly 1 and the second connection assembly 2 is that the annular terminal 21 is sleeved on the connecting stud 12, and the annular terminal 21 is also a thin structure, which further reduces the layout space required to form a closed circuit of the heating wire harness.

[0031] Optionally, the cross-section of the connecting stud 12 is circular, and the area of the cross-section of the connecting stud 12 is less than two-thirds of the area of the plate surface of the mounting plate 11.

[0032] Please refer further to Figure 1 , the connecting stud 12 is a cylindrical structure, the cross-section of the mounting plate 11 is rectangular, the connecting stud 12 is arranged in the middle area of the mounting plate 11, and the area of the cross-section of the connecting stud 12 is less than two-thirds of the area of the plate surface of the mounting plate 11. By restricting the size of the connecting stud 12, the layout space can be further saved. In an optional embodiment, while the area of the cross-section of the connecting stud 12 is less than two-thirds of the area of the plate surface of the mounting plate 11, the area of the cross-section of the connecting stud 12 is also greater than one-third of the area of the plate surface of the mounting plate 11. This design can avoid the situation where the connecting stud 12 is too small and inconvenient to connect with the annular terminal 21.

[0033] Optionally, the connecting stud 12 and the annular terminal 21 are made of the same material, both being aluminum alloy parts. In this embodiment, the connecting stud 12 and the annular terminal 21 can be made of aluminum alloy, and the aluminum alloy has good electrical conductivity and corrosion resistance, ensuring the stability and durability of the connection.

[0034] Optionally, the inner layer glass 33 is provided with an installation groove 331, the installation plate 11 is embedded in the installation groove 331, and the surface of the installation plate 11 where the connecting stud 12 is provided faces away from the outer layer glass 31 towards the inner layer glass 33.

[0035] Please refer further to Figure 1 and Figure 4 , the inner layer glass 33 is provided with an installation groove 331 whose size matches the size of the installation plate 11, the installation plate 11 is embedded in the installation groove 331, and the connecting stud 12 faces towards the vehicle interior, facilitating the connection with the annular terminal 21. In this embodiment, since the installation plate 11 is embedded in the installation groove 331, the installation plate 11 does not need to occupy additional layout space on the basis of the space originally occupied by the inner layer glass 33, and only the connecting stud 12 needs to occupy a certain layout space. Therefore, the layout space required for the heating glass of this application embodiment to realize the closed loop of the heating wire harness is further reduced.

[0036] Optionally, the thickness of the installation plate 11 is the same as the thickness of the inner layer glass 33. In this embodiment, the inner layer glass 33 is provided with an installation groove 331 whose thickness is the same as the thickness of the installation plate 11. After the installation plate 11 is embedded in the installation groove 331, the surface of the formed installation plate 11 - inner layer glass 33 structure is smooth and uniform, reducing the strength reduction of the inner layer glass 33 structure due to the installation of the installation plate 11.

[0037] Optionally, the copper foil wire harness 13 is arranged between the inner layer glass 33 and the interlayer 32. As Figure 1 and Figure 2 shown, in this embodiment, the heating cable 4 is arranged between the inner layer glass 33 and the interlayer 32, and the copper foil wire harness 13 is also arranged between the inner layer glass 33 and the interlayer 32, facilitating the connection between the copper foil wire harness 13 and the heating cable 4. Compared with the case where the copper foil wire harness 13 is arranged between the outer layer glass 31 and the interlayer 32 and still needs to be connected to the heating cable 4, the circuit layout of the copper foil wire harness 13 and the heating cable 4 in this embodiment is simpler.

[0038] Optionally, an adhesive layer is provided on the surface of the installation plate 11 facing away from the connecting stud 12. In this embodiment, after the installation plate 11 is embedded in the installation groove 331, due to the provision of the adhesive layer, the bonding between the installation plate 11 and the interlayer 32 can be realized, making the installation of the installation plate 11 more secure.

[0039] Optionally, the inner glass 33 and the outer glass 31 have the same thickness. The interlayer 32 is a resin component, and the thickness of the interlayer 32 is less than half of the thickness of the inner glass 33. In this embodiment, the thickness of the interlayer 32 being less than half of the thickness of the inner glass 33 and the outer glass 31 ensures the compactness of the structure of the glass assembly 3. In addition, the interlayer 32 is made of a resin material such as a PVB film. When the glass assembly 3 is impacted, it can prevent the glass from breaking into sharp fragments and reduce the threat to personal safety.

[0040] The embodiment of the present application also provides a vehicle, including the heating glass as described above. Since the technical solution of this embodiment includes all the technical solutions of the above embodiment, it can at least achieve all the technical effects of the above embodiment, and will not be elaborated here one by one.

[0041] Optionally, the heating glass is the front windshield of the vehicle. During the driving of the vehicle, frost, fog, water droplets, etc. on the front windshield have a greater impact on the driver. Therefore, setting the front windshield as the heating glass of the embodiment of the present application can ensure the clear vision of the driver and improve the driving safety.

[0042] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should be covered within the protection scope of the present application.
