Abstract
Description
Technical Field
[0001] This utility model generally relates to the field of steering wheel function pad technology, and specifically to an automotive steering wheel function pad body and steering wheel. Background Technology
[0002] Currently, in order to improve the functionality of car steering wheels, functional pads with heating or hands-off detection functions are usually covered on the rim of the steering wheel. In order to fix the functional pads covered on the rim of the steering wheel foam, the steering wheel foam is provided with grooves to fix the functional pads and facilitate the covering.
[0003] However, when workers are wrapping the functional pad, they first use tools to press the functional pad into the embedding groove before wrapping it. During this process, if the workers use too much force, the metal wire at the embedding groove of the functional pad may break. The broken metal wire may puncture the substrate, causing an interlayer short circuit and rendering the functional pad ineffective. Utility Model Content

[0005] On one hand, this utility model provides a functional pad for a car steering wheel, used to cover the rim of a steering wheel, wherein the rim of the steering wheel is provided with a leather groove, including:
[0006] A functional pad body, wherein at least one protective structure is provided on the area of the functional pad body corresponding to the leather groove;
[0007] The functional pad body includes a first functional pad and a second functional pad stacked together, and the protective structure is disposed between the first functional pad and the second functional pad.
[0008] According to the technical solution provided by this utility model, a shielding layer is provided between the first functional pad and the second functional pad, and the protective structure is provided between the first functional pad and the shielding layer, and / or between the second functional pad and the shielding layer.
[0009] According to the technical solution provided by this utility model, the functional pad body and the area corresponding to the leather groove are provided with a clearance groove.
[0010] According to the technical solution provided by this utility model, the clearance groove is opened in the middle of the functional pad body, and there is a gap between the clearance groove and the edges on both sides of the functional pad body. A protective structure is provided between the clearance groove and the edges on both sides of the functional pad body.
[0011] According to the technical solution provided by this utility model, the clearance groove is connected to the edge of one side of the functional pad body, and the protective structure is disposed between the clearance groove and the edge of the functional pad body.
[0012] According to the technical solution provided by this utility model, the clearance groove has a hole-like structure.
[0013] According to the technical solution provided by this utility model, the first functional pad is a sensing layer pad, the sensing layer pad includes a first substrate, and a sensing conductor wire is disposed on the first substrate.
[0014] The second functional pad is a heating layer pad, which includes a second substrate on which heating conductor wires are disposed.
[0015] According to the technical solution provided by this utility model, an avoidance area is provided around the avoidance groove;
[0016] The induction conductor wire is disposed on the first substrate in a region outside the avoidance area;

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.
[0032] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.
[0033] Example 1
[0034] refer to Figure 1-7 This utility model provides a functional pad for a car steering wheel, used to cover the steering wheel rim 1, wherein the steering wheel rim 1 is provided with a leather groove 2, including:
[0035] The functional pad body 14 has at least one protective structure provided in the area corresponding to the leather groove.
[0036] The functional pad body 14 includes a first functional pad and a second functional pad stacked together, and the protective structure is disposed between the first functional pad and the second functional pad.
[0037] Specifically, such as Figure 1 By providing a protective structure between the first functional pad and the second functional pad, and with the protective structure 3 corresponding to the insert groove 2, the position can be protected during assembly to prevent damage from workers pressing it with tools, which could lead to an interlayer short circuit between the first functional pad and the second functional pad, causing functional failure.
[0038] The protective structure 3 is preferably insulating tape, which provides both protection and insulation. Even if the functional pads are damaged during assembly, it can prevent interlayer short circuits between the first and second functional pads, thus preventing greater losses. Of course, other materials with both protective and insulating functions can also be used, and no specific limitation is made here.
[0039] Furthermore, such as Figure 5 As shown, the first functional pad is a sensing layer pad, which includes a first substrate 4, on which a sensing conductor wire 5 is disposed;
[0040] The second functional pad is a heating layer pad, which includes a second substrate 6, on which a heating conductor wire 7 is disposed.
[0041] Specifically, the induction conductor wire 5 and the heating conductor wire 7 can be sewn onto the first substrate 4 and the second substrate 6 by stitching thread 10, or fixed by other methods such as adhesive, without limitation. Both the induction conductor wire 5 and the heating conductor wire 7 are metal wires, which are connected to a controller through a control harness. The controller enables the off-hand detection function or the heating function.
[0042] Furthermore, a shielding layer 8 is provided between the first functional pad and the second functional pad, and the protective structure 3 is provided between the first functional pad and the shielding layer 8, and / or between the second functional pad and the shielding layer 8.
[0043] Specifically, a shielding layer 8 is provided between the sensing layer pad and the heating layer pad to shield the signal and prevent the sensing layer function from being affected by the heating layer pad and the internal metal structure of the steering wheel, thus ensuring the off-hand detection function. The protective structure 3 can be provided between the heating layer pad and the shielding layer 8, or between the sensing layer pad and the shielding layer 8.
[0044] Of course, multiple protective structures 3 can be set, and they can be set between the heating layer pad and the shielding layer 8, as well as between the sensing layer pad and the shielding layer 8.
[0045] Furthermore, a first adhesive layer 9 is provided on the side of the first substrate 4 near the shielding layer 8, and a second adhesive layer 13 is provided on the side of the second substrate 6 near the shielding layer 8. The first adhesive layer 9 and the second adhesive layer 13 can fix the sensing layer pad and the heating layer pad to the shielding layer 8 respectively to form a complete functional pad. The protective structure 3 can be provided between the shielding layer 8 and the first adhesive layer 9 and the second adhesive layer 13, or between the corresponding adhesive layer and the substrate, or on both sides. No specific limitation is made here.
[0046] Furthermore, the functional pad body 14 has a relief groove 11 in the area corresponding to the embedding groove 2. The relief groove 11 is used for positioning, and the area around the relief groove 11 is designated as the worker's pressing area. The worker can press the pad body around the relief groove 11 into the embedding groove 2. Compared with pressing directly without grooves, this can reduce the worker's pressing area and reduce damage to the functional pad body. Combined with the protective structure 3, it further reduces the risk of conductor wire breakage in this area.
[0047] Specifically, such as Figure 2 As shown, the clearance groove 11 is formed in the middle of the functional pad body 14, and there is a gap between the clearance groove 11 and the edges on both sides of the functional pad body 14. A protective structure 3 is provided between the clearance groove 11 and the edges on both sides of the functional pad body 14.
[0048] like Figure 3 As shown, the clearance groove 11 can also communicate with the edge of one side of the functional pad body 14, and the protective structure 3 is disposed between the clearance groove 11 and the edge of the functional pad body 14.
[0049] In both of the above methods, the clearance groove 11 is cut out together with the functional pad body 14 during molding. Alternatively, it can be done as shown in Figure 4, where the clearance groove 11 has a hole-like structure. During assembly, it is cut along the line connecting multiple clearance grooves to avoid the position of the insert groove 2.
[0050] Furthermore, such as Figure 2-4 As shown, a clearance area 12 is also provided around the clearance groove 11.
[0051] The induction conductor wire 5 is disposed on the first substrate 4 in an area outside the avoidance area 12;
[0052] The heating conductor wire 7 is disposed on the second substrate 6 in an area outside the avoidance area 12.
[0053] The induction conductor wire 5 and the heating conductor wire 7 are not installed in the avoidance area 12 to further reduce the risk of conductor wire breakage in this area.
[0054] Example 2
[0055] This utility model also provides a steering wheel, such as Figure 1-7 As shown, it includes a steering wheel rim 1, on which a leather groove 2 is provided, and the steering wheel rim 1 is covered with a car steering wheel functional pad as described in any of the above embodiments.
[0056] Therefore, by setting a protective structure on the functional pad body 14 at the position corresponding to the embedded groove, it is possible to prevent the metal wire at the embedded groove from being broken by the tool during assembly of the functional pad, thus preventing interlayer short circuits.
[0057] The above description is merely a preferred embodiment of this utility model and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of this utility model is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this utility model.
