Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a heating structure for vehicle glass, a vehicle glass structure, and a vehicle. Background Technology

[0002] Heating wires are typically printed on vehicle windows, such as windshields. The two ends of these heating wires are connected to the vehicle's power supply via a wiring harness, forming a circuit. When the windshield fogs or frosts up, the power supply provides power to the heating wires, causing them to heat up and dissipate the fog or frost, thus ensuring clear visibility.

[0003] In related technologies, one end of the heating wire harness connected to the heating wire has a metal clip, which is welded to the heating wire. However, during the welding process, thermal stress can easily form on the windshield, causing it to crack, resulting in a low welding pass rate. Utility Model Content

[0016] And / or, all the spacers have the same thickness in the direction from the heating wire to the metal terminal;

[0017] And / or, in the direction from one end of the metal terminal near the wire harness to the other end of the metal terminal away from the wire harness, the sum of the dimensions of all the spacers is not greater than 2 / 5 of the length of the metal terminal.

[0022] Thirdly, this utility model provides a vehicle including the vehicle glass structure described above.

[0023] This utility model provides a vehicle glass heating structure, an automotive glass structure, and a vehicle. By placing a heating wire on the vehicle glass, with the metal terminals of the wiring harness located on the side of the heating wire away from the glass, and a separator is provided between some of the metal terminals and the heating wire to increase the distance between the metal terminals and the glass, at least during welding.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0029] Heating wires are typically printed on vehicle windows, such as windshields. The two ends of these heating wires are connected to the vehicle's power supply via a wiring harness, forming a circuit. When the windshield fogs or frosts up, the power supply provides power to the heating wires, causing them to heat up and dissipate the fog or frost, thus ensuring clear visibility.

[0030] In related technologies, one end of the heating wire harness connected to the heating wire has a metal clip, which is welded to the heating wire. However, during the welding process, thermal stress can easily form on the windshield, causing it to crack, resulting in a low welding pass rate.

[0031] Based on this, the present invention provides a heating structure for vehicle glass, an automotive glass structure, and a vehicle. By setting a separator between a portion of the metal terminals and a heating wire disposed on the glass, the metal terminals can be welded to the heating wire in areas outside the separator, ensuring electrical connection performance. Furthermore, during the welding of the metal terminals and the heating wire, the separator acts as a physical isolation between the metal terminals and the glass, increasing the distance between them. This prevents the metal terminals from contacting the glass during welding, thus avoiding the phenomenon of localized overheating of the glass causing thermal stress and cracking, and improving the welding qualification rate.

[0032] The heating structure for vehicle glass, the automotive glass structure, and the vehicle provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments:

[0033] Reference Figure 1 and Figure 2 As shown, this embodiment provides a heating structure 10 for vehicle glass. The heating structure 10 can be installed on the vehicle glass 20 to heat the glass 20, thereby dissipating fog or frost on the glass 20 and ensuring clear visibility.

[0034] In a specific implementation, the heating structure 10 can be electrically connected to the vehicle's power supply, and the power supply can supply power to the heating structure 10, causing the heating structure 10 to be energized and generate heat, thereby heating the glass 20 on which it is located.

[0035] For details, please refer to Figure 1 and Figure 2 As shown, the heating structure 10 includes a heating wire 1, a wiring harness 2, and a separator 3. The heating wire 1 is disposed on the glass 20 of the vehicle, and the heating wire may be printed on the glass 20, for example. One end of the wiring harness 2 has a metal terminal 21, which is located on the side of the heating wire 1 facing away from the glass 20. The separator 3 is disposed between a portion of the metal terminal 21 and the heating wire 1 to increase the spacing between the metal terminal 21 and the glass 20, at least when the metal terminal 21 is soldered to the heating wire 1.

[0036] By setting the separator 3, the separator 3 is located between part of the metal terminal 21 and the heating wire 1. Therefore, the projection of the separator 3 on the glass 20 is smaller than the projection of the metal terminal 21 on the glass 20. In this way, the metal terminal 21 can be welded to the heating wire 1 in the area outside the separator 3, ensuring the connection performance between the metal terminal 21 and the heating wire 1, and enabling the heating wire 1 and the wire harness 2 to achieve electrical connection.

[0037] Furthermore, the separator 3 serves to isolate the metal terminal 21 from the heating wire 1. The separator 3 physically isolates the metal terminal 21 from the heating wire 1, and the distance between the metal terminal 21 and the glass 20 in the area where the separator 3 is located is larger. In this way, the metal terminal 21 will not come into direct contact with the glass 20 during the welding process, thereby avoiding the phenomenon of thermal stress caused by excessive local temperature in the glass 20 during the welding process, making the welding stress more uniform and improving the welding qualification rate.

[0038] Meanwhile, a separator 3 is provided between the metal terminal 21 and the heating wire 1. During the welding process, the separator 3 ensures that the metal terminal 21 and the glass 20 are spaced apart by the heating wire 1 and the separator 3. This increases the distance between the metal terminal 21 and the glass 20, resulting in a larger gap between them during welding. This gap provides space for the flux, such as solder, to fill the space between the metal terminal 21 and the heating wire 1 more fully, ensuring the flux thickness, preventing incomplete soldering, and improving the welding quality between the metal terminal 21 and the heating wire 1.

[0039] In some implementations, the heating wire 1 can be, for example, silver paste printed on the glass 20 during the glass 20 production process. After the silver paste solidifies, it forms the printed heating wire 1 on the glass 20 and forms an integral structure with the glass 20.

[0040] Of course, in other implementations, the heating wire 1 can also be silver powder, silver fiber, carbon fiber, etc., printed on the glass 20.

[0041] In practice, the end of the wiring harness 2 that is away from the heating wire 1 can be electrically connected to the vehicle's power supply, so that the power supply can supply power to the heating wire 1, causing the heating wire 1 to heat up, thereby heating the glass 20.

[0042] In some embodiments, the separator 3 can be a flexible separator, which on the one hand prevents the separator 3 from scratching the glass 20, heating wire 1 and metal terminal 21, and on the other hand, the separator 3 can adapt to the thermal expansion and contraction of the welding flux, thereby avoiding the phenomenon of cracking of the welding flux between the metal terminal 21 and the heating wire 1 to a certain extent, and further improving the welding quality.

[0043] In practice, the separator 3 can be made of materials such as silicone rubber or plastic.

[0044] The vehicle glass heating structure 10 provided by this utility model involves printing a heating wire 1 onto the vehicle glass 20. The metal terminal 21 of the wiring harness 2 is located on the side of the heating wire 1 facing away from the glass 20. A separator 3 is provided between the metal terminal 21 and the heating wire 1, and the projection of the separator onto the glass 20 is smaller than the projection of the metal terminal 21 onto the glass 20. This ensures that the metal terminal 21 and the glass 20 are spaced apart, at least during welding. Because the separator 3 is provided between the metal terminal 21 and the heating wire 1, and the projection of the separator onto the glass 20 is smaller than the projection of the metal terminal 21 onto the glass 20, the metal terminal 21 can be welded to the heating wire 1 in areas outside the separator 3, ensuring electrical connection performance. Furthermore, the separator 3 acts as a physical barrier between the metal terminal 21 and the glass 20, preventing the metal terminal 21 from contacting the glass 20 during welding. This avoids the phenomenon of thermal stress and cracking caused by excessively high local temperatures in the glass 20, thus improving the welding qualification rate.

[0045] Meanwhile, the metal terminal 21 and the glass 20 are physically separated by the separator 3, so that there is a certain gap between the metal terminal 21 and the glass 20, which provides a certain space for the welding flux. In this way, the welding flux can be more fully arranged between the metal terminal 21 and the heating wire 1, thereby ensuring the thickness of the welding flux, avoiding false soldering, improving the welding quality, and further ensuring the electrical connection performance between the metal terminal 21 and the heating wire 1.

[0046] In some embodiments, the separator 3 is at least connected to the side of the metal terminal 21 facing the glass 20.

[0047] By connecting the separator 3 to the side of the metal terminal 21 facing the glass 20, the separator 3 and the metal terminal 21 are connected to form an integral structure. During assembly, the metal terminal 21 is arranged on the side of the heating wire 1 away from the glass 20, and the separator 3 is arranged facing the heating wire 1, which makes welding convenient and helps to improve work efficiency.

[0048] In some implementations, the separator 3 may be bonded to the metal terminal 21. Of course, in other implementations, the separator 3 may also be snapped onto the metal terminal 21.

[0049] In other embodiments, the separator 3 may also be disposed on the glass 20 and located on the side of the heating wire 1 opposite to the glass 20.

[0050] Definition: The direction between the end of the metal terminal 21 closest to the wire harness 2 and the end of the metal terminal 21 furthest from the wire harness 2 is the length direction of the metal terminal 21 (refer to...). Figure 1 and Figure 2 (in the X direction).

[0051] The horizontal direction perpendicular to the length direction of the metal terminal 21 is the width direction of the metal terminal 21 (reference). Figure 2 (in the Y direction).

[0052] The thickness direction of the metal terminal 21 is the same as the thickness direction of the glass 20 (reference). Figure 1 and Figure 2 (Z direction in the middle).

[0053] For example, the metal terminal 21 may be a rectangular metal connecting piece 12.

[0054] In some embodiments, the separator 3 may be arranged at least along the width direction of the metal terminal 21 on the side of the metal terminal 21 facing the glass 20. In other embodiments, the separator 3 may also be arranged at least along the length direction of the metal terminal 21 on the side of the metal terminal 21 facing the glass 20. Of course, the separator 3 may also be arranged in other suitable directions on the side of the metal terminal 21 facing the glass 20.

[0055] refer to Figure 2 As shown, in some embodiments, the separator 3 includes a separator ring that is sleeved on the circumferential outer side of the metal terminal 21.

[0056] By forming the separator 3 into a separator ring, which is sleeved on the outer circumference of the metal terminal 21, that is, the separator 3 is arranged on the outer ring of the metal terminal 21, the arrangement of the metal terminal 21 does not have directional requirements during assembly. As long as the metal terminal 21 is placed on the side of the heating wire 1 away from the glass 20, the separator 3 is sandwiched between the metal terminal 21 and the glass 20, which improves the convenience of welding and further improves work efficiency.

[0057] In practice, the axial direction of the separator ring can be parallel to the length direction of the metal terminal 21, that is, the separator ring is arranged along the width direction of the metal terminal 21.

[0058] For example, the separator ring may be sleeved on the middle part of the metal terminal 21 in the length direction, with the two sides of the separator ring in the axial direction located on both sides of the center line in the length direction of the metal terminal 21.

[0059] In practice, the side of the metal terminal 21 facing the glass 20 has a welding surface to facilitate welding. The shape of the welding surface can, for example, match the shape of the corresponding position on the glass 20.

[0060] In some embodiments, the projected area of ​​the separator 3 on the glass 20 is not greater than 2 / 5 of the projected area of ​​the metal terminal 21 on the glass 20. That is, the area occupied by the separator 3 on the welding surface of the metal terminal 21 is not greater than 2 / 5 of the welding surface of the metal terminal 21. In this way, while achieving physical isolation, sufficient welding joint surface is ensured between the metal terminal 21 and the heating wire 1, thus ensuring the welding strength and electrical connection performance between the two.

[0061] refer to Figure 1 and Figure 2 As shown, in some embodiments, in the direction along the glass 20 to the metal terminal 21 (refer to...) Figure 2 In the Z direction (that is, along the thickness direction of glass 20), the thickness of the separator 3 is 0.3mm-0.5mm, which ensures the thickness of the welding flux, further avoids false welding, and ensures the welding quality.

[0062] refer to Figure 1 and Figure 2 As shown, in some embodiments, there are at least two separators 3, and at least two separators 3 are spaced apart along the length of the metal terminal 21. That is, at least two separators 3 are spaced apart between the metal terminal 21 and the glass 20. In this way, there are at least two physical isolations between the metal terminal 21 and the glass 20. The physical isolation effect between the two is better, thereby further preventing the metal terminal 21 from coming into contact with the glass 20 during the welding process, further preventing the phenomenon of the glass 20 cracking due to excessive local temperature and thermal stress, and improving the welding qualification rate.

[0063] In some embodiments, a separator 3 is provided at both ends of the metal terminal 21. That is, a separator 3 is provided at the end of the metal terminal 21 near the wire harness 2, and a separator 3 is also provided at the end of the metal terminal 21 away from the wire harness 2. In this way, the separator 3 at both ends of the metal terminal 21 more effectively isolates the metal terminal 21, and the metal terminal 21 will not come into contact with the glass 20. The physical isolation effect is good, which not only avoids the phenomenon of thermal stress and cracking caused by excessive local temperature of the glass 20, but also ensures the effective thickness of the welding flux and avoids the occurrence of poor soldering.

[0064] For example, refer to Figure 1 and Figure 2 As shown, two separating rings are sleeved on the metal terminal 21, and the two separating rings are respectively sleeved on the two ends of the metal terminal 21 in the length direction.

[0065] In some embodiments, all separators 3 have the same thickness in the direction from the heating wire 1 to the metal terminal 21, which ensures the thickness of the welding flux, further avoids incomplete welding, and ensures the welding quality.

[0066] In some embodiments, in the direction from one end of the metal terminal 21 near the wire harness 2 to the other end of the metal terminal 21 away from the wire harness 2, the sum of the dimensions of all the separators 3 is not greater than 2 / 5 of the length of the metal terminal 21. That is, in the length direction of the metal terminal 21, the sum of the dimensions occupied by all the separators 3 on the welding surface of the metal terminal 21 is not greater than 2 / 5 of the length of the metal terminal 21. In this way, while achieving physical isolation, sufficient welding joint surface is ensured between the metal terminal 21 and the heating wire 1, ensuring the welding strength and electrical connection performance between the two.

[0067] refer to Figure 2 As shown, in some embodiments, the heating wire 1 includes a heating wire body 11 and a connecting piece 12. Both the heating wire body 11 and the connecting piece 12 are printed on one side of the glass 20, and the heating wire body 11 and the connecting piece 12 are connected to achieve an electrical connection between them. Metal terminals 21 are soldered to the side of the connecting piece 12 facing away from the glass 20. A separator 3 is disposed between a portion of the metal terminals 21 and the connecting piece 12. The structure is simple, easy to manufacture, and convenient for soldering.

[0068] For specific implementation, refer to Figure 2 As shown, the connecting piece 12 can be, for example, a silver paste sheet printed on the glass 20. The area of ​​the silver paste sheet can be larger than the area of ​​the metal terminal 21, which not only facilitates welding but also makes the electrical connection performance between the heating wire body 11 and the metal terminal 21 better.

[0069] This embodiment also provides an automotive glass structure, which includes glass 20 and a heating structure 10 for the vehicle glass.

[0070] The heating structure 10 for the vehicle glass is printed on one side of the glass 20.

[0071] In practice, the heating structure 10 of the vehicle glass can be printed on the side of the glass 20 facing the inside of the vehicle, that is, the heating structure 10 of the vehicle glass can be printed on the inside of the glass 20.

[0072] Glass 20 can be, for example, the windshield, rear windshield, or window glass of a vehicle.
