[0024] Example

[0025] Embodiment 1 of this utility model provides a transmission structure, such as... Figure 1 As shown, the system includes a substrate 1, a transmission line 2, and a coating unit. The substrate 1, the transmission line 2, and the coating unit are all flexible. The transmission line 2 is disposed on the substrate 1, and the coating unit is provided on the upper surface of the transmission line 2 (i.e., the side facing away from the substrate 1). The coating unit includes a multi-layer coating body 3, or the thickness of the coating unit is greater than a set threshold.

[0026] In the transmission structure of this utility model embodiment, the coating unit has two implementation methods: one is that the coating unit includes multiple layers of coating body 3, and the other is that the thickness of the coating unit is greater than a set threshold. Regardless of which method is used, the coating unit can be guaranteed to have a certain thickness, thereby improving its high-voltage resistance. Therefore, this embodiment, by employing a coating unit, can prevent high-voltage breakdown of the coating unit, meeting the requirements of high-voltage transmission and thus having a wider range of applications. The substrate 1, the transmission line 2, and the unit are all flexible, allowing the transmission structure to be applied in multiple scenarios. Furthermore, if the coating unit includes multiple layers of coating body 3, the multiple layers of coating body 3 not only have better wear resistance but also provide a waterproof seal for the transmission line 2.

[0027] In this embodiment, substrate 1 provides structural support for the transmission structure, transmission line 2 transmits power or signals, and the coating unit prevents high-voltage breakdown. Substrate 1, transmission line 2, and coating unit are all flexible; therefore, the transmission structure provided in this embodiment is also a flexible circuit, meaning it can be bent to have good flexibility and is suitable for various scenarios, such as narrow gaps, irregular circuit lines, and other situations.

[0028] It should be noted that for the first form of the film coating unit, if the film coating unit includes a multi-layer film coating body 3, the thickness of the film coating body 3 can be thinner, but due to the use of a multi-layer film coating body 3, the entire film coating unit can still meet the high-voltage transmission requirements.

[0029] For the second form of the film coating unit, only the thickness of the film coating unit is greater than the set threshold value, if the film coating unit is one layer, and the thickness itself is greater than the set threshold value, that is, only one layer of film coating unit is set, which can also meet the high-voltage requirement, for example, the set threshold value is 0.09mm-0.18mm. Further, the thickness of the film coating unit can also be between 0.09mm-0.3mm, which can not only ensure that the thickness of the entire transmission structure is thin, but also ensure that the entire transmission structure will not be punctured by high voltage. In the specific implementation process of the present embodiment 1, as shown in Figure 1 , the transmission lines 2 are at least two, and the adjacent two transmission lines 2 are spaced apart on the substrate 1.

[0030] More specifically, the transmission lines 2 are at least two, and the transmission lines 2 can be copper lines for transmitting signals or copper lines for transmitting power. All transmission lines 2 are located in the same layer, so that the thickness of the entire transmission structure is thin, which can be applied to scenes that require thin space occupation, thereby meeting the use requirements of multiple scenes. Moreover, the adjacent transmission lines 2 are spaced apart, which avoids interference between different transmission lines 2 when transmitting different signals. For example: if one transmission line 2 transmits power and the other transmission line 2 transmits signals, the two transmission lines 2 are spaced apart, which can avoid interference between them.

[0031] In the specific implementation process of the present embodiment 1, as shown in Figure 1 , the lower surface of the substrate 1 (i.e. the surface away from the transmission lines 2) is also provided with a plurality of film coating bodies 3. The arrangement of the film coating body 3 on the lower surface of the substrate 1 can further enhance the reliability of the transmission structure when transmitting high voltage.

[0032] In the specific implementation process of the present embodiment 1, as shown in Figure 1 , the upper surface of the transmission line 2 and the lower surface of the substrate 1 are both provided with at least three film coating bodies 3.

[0033] More specifically, the upper surface of the transmission line 2 and the lower surface of the substrate 1 are both provided with at least three film coating bodies 3, which can better prevent high voltage from puncturing the film coating body 3.

[0034] In the specific implementation process of the present embodiment 1, as shown in Figure 1 , the thickness of each film coating body 3 is 0.03-0.1mm.

[0035] The thickness of the film body 3 is set in the range, which can ensure that the whole transmission structure is thin and will not be broken by high pressure.

[0036] In the embodiment 1, the number of layers of the film body 3 arranged on the lower surface of the substrate 1 is less than the number of layers of the film body 3 arranged on the upper surface of the transmission line 2.

[0037] Alternatively, the number of layers of the film body 3 arranged on the lower surface of the substrate 1 is equal to the number of layers of the film body 3 arranged on the upper surface of the transmission line 2.

[0038] More specifically, the film body 3 on the upper surface of the transmission line 2 has three or more layers, and the film body 3 on the lower surface of the substrate 1 has three layers. Since the substrate 1 has certain pressure resistance, the number of layers of the film body 3 on the lower surface of the substrate 1 can be less than the number of layers of the film body 3 on the upper surface of the transmission line 2.

[0039] In other embodiments, if the thickness of the substrate 1 is relatively thick, the film body 3 can not be arranged on the lower surface of the substrate 1, as shown in FIG. 4. Figure 2

[0040] In the embodiment 1, the material of the film body 3 is polyimide.

[0041] More specifically, the polyimide material has non-flammability, geometric stability, high tear strength, and the ability to withstand welding temperature.

[0042] In the embodiment 1, the forming process of the film body 3 is hot pressing.

[0043] More specifically, the forming process of the film body 3 is hot pressing, which can make the film body 3 more closely combined with the transmission line 2, thereby reducing the thickness of the transmission structure.

[0044] The working process of the embodiment 1 is as follows: the film unit of the transmission structure can prevent high-voltage breakdown of the film unit and meet the requirements of high-voltage transmission. The substrate 1, the transmission line 2 and the film unit can be bent, which meets the requirement that the transmission structure can be applied to multiple scenes. At the same time, the multi-layer film body 3 not only has better wear resistance, but also can seal and waterproof the transmission line 2. The number of transmission lines 2 can be multiple, which can include copper wires for transmitting power and copper wires for transmitting signals, and all the transmission lines 2 are located in the same layer, which can make the whole transmission structure thin and meet the use requirements of multiple scenes.

[0045] Embodiment 2

[0046] ​The transmission structure described in embodiment 1 is applied to transmission of electric energy or signal.

[0047] The transmission structure of embodiment 1 can be used for transmission of high voltage of 220V or above, and the setting of the film coating unit can prevent high voltage from breaking through the film coating unit. In addition, the film coating unit comprises the multilayer film coating body 3, and can also consider sealing and waterproofing of the transmission line 2, and has good wear resistance, and at this time, the transmission line 2 is used for transmission of power supply.

[0048] The transmission structure can also be used for transmission of signal, and at this time, the transmission line 2 is used for transmission of signal.

[0049] The transmission structure can also be used for transmission of power supply and signal at the same time, the transmission line 2 is multiple, and can comprise copper wires for transmission of power supply and copper wires for transmission of signal, and all the copper wires are located in the same layer, and the copper wires for transmission of power supply and the copper wires for transmission of signal have a certain distance therebetween to avoid mutual interference.

[0050] Embodiment 3

[0051] The vehicle-mounted frequency interference meter provided by the embodiment 3 of the utility model discloses a transmission structure, a vehicle body inner module and a roof module, the vehicle body inner module is connected the roof module through the transmission structure.

[0052] The vehicle body inner module and the roof module usually need to transmit power supply or signal, and need to realize electrical connection of the module on the roof and the module in the vehicle body through a cable to transmit power supply or signal. However, since the cable is thick, the structure of the vehicle body itself often needs to be damaged to provide space for the cable to pass through. Based on this, when the transmission structure provided in the above embodiments is used for electrical connection of the vehicle body inner module and the roof module, the transmission structure has good flexibility and can be bent, the transmission structure can be arranged in the gap between the tailgate in the closed state and the vehicle body main body, the gap formed between the door and the vehicle body main body or the gap formed between the window and the door, so that the transmission of power supply and signal can be realized without damaging the structure of the vehicle body itself.

[0053] In summary, the film coating unit of the transmission structure can prevent high voltage from breaking through the film coating unit, meet the requirements of high voltage transmission, and can expand the application range.

[0054] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be limited by the protection scope of the claims.
