Description

Technical Field

[0001] This application relates to the field of automotive windshield heating technology, and in particular to a windshield heating connector, windshield device, and vehicle. Background Technology

[0002] Based on market demand in cold regions, heating devices are typically installed inside the windshields of automobiles. The positive and negative terminals of these heating devices are connected to the vehicle's power supply to heat the windshield, removing frost and fog from the glass surface and ensuring the normal operation of the vehicle in cold climates.

[0003] However, current heating devices typically use adhesive to fix the positive and negative terminals to the vehicle body separately. On one hand, the adhesive used to bond the positive and negative terminals (e.g., glue, tape) is prone to aging due to environmental factors such as temperature and light, leading to detachment of either the positive or negative terminal. Furthermore, friction between the terminals and the vehicle body sheet metal can cause damage, posing a serious safety hazard. On the other hand, the independent placement of the positive and negative terminals results in numerous fixing points for the heating device (i.e., separate fixing of the positive and negative terminals), making the assembly process between the vehicle body and windshield cumbersome, increasing the cost of fixing materials, and impacting assembly efficiency. Utility Model Content

[0004] The purpose of this application is to provide a windshield heating connector, windshield device, and vehicle, in order to solve to some extent the technical problems existing in the prior art. The positive and negative connectors of the heating device are usually fixed to the vehicle body by bonding, and the adhesive (e.g., glue, tape) used to bond the positive and negative connectors is prone to aging, causing the positive or negative connectors to fall off. In some cases, the positive or negative connectors are easily damaged by friction with the vehicle body sheet metal, resulting in serious safety hazards. The positive and negative connectors are set up independently, and the positive and negative connectors need to be fixed separately, which makes the assembly process of the vehicle body and windshield cumbersome, increases the cost of fixing materials, and affects the assembly efficiency.

[0005] According to a first aspect of this application, a windshield heating connector is provided for connecting a vehicle body and a windshield heating wire. The windshield heating connector includes a terminal block, a first lead wire, and a second lead wire. The vehicle body is provided with a fixing groove, and the terminal block is provided with a fixing clip that can engage with the fixing groove.

[0006] The first lead and the second lead are respectively led out from the terminal block. The first lead is used to be electrically connected to the positive bus of the windshield heating wire, and the second lead is used to be electrically connected to the negative bus of the windshield heating wire.

[0007] Preferably, the terminal block includes a first housing and a second housing arranged side by side along a predetermined direction, with the first lead extending from the first housing and the second lead extending from the second housing.

[0008] Preferably, the first box body, the second box body, and the fixing card are connected as a single unit;

[0009] The fixing clip is disposed between the first box and the second box.

[0010] Preferably, the first lead and the second lead are led out from the same side of the terminal block.

[0011] Preferably, the end of the first lead away from the terminal block is provided with a first bend for accommodating the positive busbar;

[0012] The end of the second lead away from the terminal block is provided with a second bend for accommodating the negative busbar.

[0013] Preferably, it further includes a first connecting piece and a second connecting piece extending from the terminal block, wherein the first lead is electrically connected to the positive wiring harness of the vehicle body via the first connecting piece, and the second lead is electrically connected to the negative wiring harness of the vehicle body via the second connecting piece.

[0014] Preferably, the first connecting piece and the second connecting piece are respectively led out from both ends of the terminal block in the predetermined direction.

[0015] According to a second aspect of this application, a windshield device is provided, including the aforementioned windshield heating wire and the windshield heating connector described in any of the aforementioned embodiments. Therefore, it has all the beneficial technical effects of the windshield heating connector, which will not be repeated here.

[0016] Specifically, the windshield heating wire includes the aforementioned positive busbar and the aforementioned negative busbar.

[0017] Preferably, it also includes a windshield, which comprises an outer glass layer and an inner glass layer, and the windshield heating wire is embedded between the outer glass layer and the inner glass layer.

[0018] According to an embodiment of the third aspect of this application, a vehicle is also provided, including the vehicle body described above, the windshield heating connector described in any of the above embodiments, or the windshield device described in any of the above embodiments. Therefore, it has all the beneficial technical effects of the windshield heating connector and the windshield device, which will not be repeated here.

[0019] Compared with the prior art, the beneficial effects of this application are as follows:

[0020] The windshield heating connector provided in this application, based on the aforementioned technical features, integrates the positive and negative terminals of existing heating devices by extending both the first lead for electrical connection to the positive busbar of the windshield heating wire and the second lead for electrical connection to the negative busbar of the windshield heating wire from the terminal block. Furthermore, by providing a fixing clip on the terminal block that engages with a fixing slot on the vehicle body, the windshield heating connector is fixed to the vehicle body through the engagement of the fixing clip with the fixing slot. This not only effectively replaces the current method of bonding the connector of the heating device to the vehicle body, improving the stability of the fixation between the windshield heating connector and the vehicle body, but also allows the windshield device to simultaneously fix the first lead for electrical connection to the positive busbar and the second lead for electrical connection to the negative busbar simply by engaging the fixing clip with the fixing slot, effectively simplifying the connection operation between the windshield heating connector and the vehicle body and improving assembly efficiency.

[0037] The following reference Figures 1 to 6 This application describes a windshield heating connector 1, a windshield device, and a vehicle according to some embodiments thereof.

[0038] See Figures 1 to 6 As shown, an embodiment of the first aspect of this application provides a windshield heating connector for connecting a vehicle body 3 and a windshield heating wire. The windshield heating connector 1 includes a terminal block 11, a first lead 121, and a second lead 122. The vehicle body 3 is provided with a fixing groove 311, and the terminal block 11 is provided with a fixing clip 113 that can engage with the fixing groove 311. The first lead 121 and the second lead 122 are respectively led out from the terminal block 11. The first lead 121 is used for electrical connection to the positive busbar of the windshield heating wire, and the second lead 122 is used for electrical connection to the negative busbar of the windshield heating wire.

[0039] According to the aforementioned technical features, the windshield heating connector integrates the positive and negative terminals of the current heating device by extending both the first lead 121 (for electrical connection to the positive busbar of the windshield heating wire) and the second lead 122 (for electrical connection to the negative busbar of the windshield heating wire) from the terminal block 11. Furthermore, by providing a fixing clip 113 on the terminal block 11 that engages with the fixing groove 311 of the vehicle body 3, the windshield heating connector 1 is fixed to the vehicle body 3 through the engagement of the fixing clip 113 with the fixing groove 311. This not only effectively replaces the current method of bonding the heating device connector to the vehicle body 3, improving the stability of the fixation between the windshield heating connector 1 and the vehicle body 3, but also allows the windshield device to simultaneously fix the first lead 121 (for electrical connection to the positive busbar) and the second lead 122 (for electrical connection to the negative busbar) simply by engaging the fixing clip 113 with the fixing groove 311, effectively simplifying the connection operation between the windshield heating connector 1 and the vehicle body 3 and improving assembly efficiency.

[0040] Preferably, such as Figures 1 to 3 As shown, the terminal block 11 may include a first housing 111 and a second housing 112 arranged side by side along a predetermined direction F1. The first lead 121 can be led out from the first housing 111, and the second lead 122 can be led out from the second housing 112. Thus, the first housing 111 and the second housing 112 arranged side by side along the predetermined direction F1 allow the terminal block 11 to extend along the predetermined direction F1 so that the terminal block 11 can adapt to the edge shape of the windshield 2, so that the windshield heating connector 1 can be hidden in the sheet metal frame of the vehicle body 3 for fixing the windshield 2. On the other hand, the first housing 111 can provide space for the connection of the first lead 121 to the wiring harness of the vehicle body 3, and correspondingly, the second housing 112 can provide space for the connection of the second lead 122 to the wiring harness of the vehicle body 3.

[0041] Preferably, such as Figures 1 to 3 As shown, the first housing 111, the second housing 112, and the fixing card 113 can be connected as a whole to ensure the stability of the terminal block 11.

[0042] like Figure 2 As shown, the aforementioned fixing clip 113 can be a limiting pin, but it is not limited to this. As long as the fixing clip 113 and the fixing groove 311 can be locked together, the aforementioned fixing clip 113 can also be a locking structure.

[0043] Preferably, such as Figure 1 As shown, the aforementioned fixing clip 113 can be disposed between the first box 111 and the second box 112 to ensure the uniformity of the force on the fixing clip 113 and improve the connection stability between the terminal block 11 and the vehicle body 3.

[0044] Preferably, such as Figure 1 and Figure 2 As shown, the first lead 121 and the second lead 122 can both be led out from the same side of the terminal block 11, that is, the first lead 121 and the second lead 122 are respectively led out from the same side of the first housing 111 and the second housing 112, so as to facilitate electrical connection with the windshield heating wire.

[0045] Preferably, such as Figure 1 , Figure 2 and Figure 6 As shown, the end of the first lead 121 away from the terminal block 11 is provided with a first bend 1210 for accommodating the positive busbar. On the one hand, this increases the contact area between the positive busbar and the first lead 121 to ensure the stability of the electrical connection between the positive busbar and the first lead 121. On the other hand, the structure of the first bend 1210 covering the positive busbar facilitates the first lead 121 to extend between the outer glass and the inner glass 22.

[0046] It should be noted that, as Figure 1 As shown, the first bend 1210 can be understood as an arc structure formed by bending the end of the first lead 121 away from the terminal block 11 by 180°, which can wrap around the positive busbar.

[0047] Optionally, the inner side of the first bend 1210 can be welded to the positive busbar to improve the connection stability between the first lead 121 and the positive busbar.

[0048] Optionally, such as Figures 1 to 3 As shown, the first lead 121 can be a flat line. On the one hand, this can further increase the contact area between the positive busbar and the first lead 121. On the other hand, it facilitates the bending of the first lead 121 so that the first lead 121 can extend into the interlayer of the windshield glass 2.

[0049] Similarly, such as Figure 1 , Figure 2 and Figure 6As shown, the end of the second lead 122 away from the terminal block 11 is provided with a second bend 1220 for accommodating the negative busbar. The structure and beneficial effects of the second lead 122 and the second bend 1220 are similar to those of the first lead 121 and the first bend 1210, and will not be described again here.

[0050] In an embodiment, preferably, such as Figures 1 to 3 As shown, the windshield heating connector 1 may also include a first connecting piece 131 and a second connecting piece 132 extending from the terminal block 11. The first lead 121 is electrically connected to the positive wiring harness of the vehicle body 3 via the first connecting piece 131, and the second lead 122 is electrically connected to the negative wiring harness of the vehicle body 3 via the second connecting piece 132, so that the windshield heating connector 1 and the wiring harness of the vehicle body 3 can be electrically connected through the first connecting piece 131 and the second connecting piece 132.

[0051] Preferably, such as Figures 1 to 3 and Figure 6 As shown, the first connecting piece 131 and the second connecting piece 132 are respectively led out from the two ends of the terminal block 11 in the predetermined direction F1, so that the wiring harness of the vehicle body 3 can be arranged along the sheet metal frame of the vehicle body 3 for fixing the windshield 2.

[0052] Preferably, the first connecting piece 131 and the first lead 121 can be electrically connected within the first housing 111.

[0053] Preferably, the second connecting piece 132 and the second lead 122 can be electrically connected within the second housing 112.

[0054] See Figure 4 The second aspect of this application also provides a windshield device, including the windshield heating wire and the windshield heating connector described in any of the above embodiments, and thus has all the beneficial technical effects of the windshield heating connector, which will not be repeated here.

[0055] Specifically, the windshield heating wire includes the aforementioned positive busbar and the aforementioned negative busbar.

[0056] Preferably, such as Figure 4 As shown, the windshield device also includes a windshield glass 2, which comprises an outer glass layer and an inner glass layer 22, with the windshield heating wire embedded between the outer glass layer and the inner glass layer 22. In other words, the positive and negative busbars are also respectively embedded between the outer glass layer and the inner glass layer 22.

[0057] It should be noted that the way and distribution structure of the windshield heating wire embedded between the outer glass and the inner glass 22 are existing technologies in the field and will not be described in detail here.

[0058] Preferably, such as Figure 4 As shown in the figure, an example of the windshield device including two windshield heating joints 1 is illustrated, wherein the two heating joints can be respectively disposed at both ends of the windshield glass 2 in the vehicle width direction W.

[0059] like Figure 4 As shown in the figure, W can be an example of the vehicle width direction W mentioned above, and H can be an example of the vehicle height direction H. The vehicle width direction W is perpendicular to the vehicle height direction H.

[0060] Preferably, such as Figure 4 As shown, the two windshield heating connectors 1 are symmetrically arranged about the centerline of the windshield device in the vehicle width direction W, so as to adapt to the existing left and right symmetrical wiring harness arrangement structure of the vehicle body 3.

[0061] See Figure 5 and Figure 6 The third aspect of this application also provides a vehicle, including the vehicle body 3 described above, the windshield heating connector described in any of the above embodiments, or the windshield device described in any of the above embodiments, and thus has all the beneficial technical effects of the windshield heating connector and the windshield device, which will not be repeated here.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
