[0003] In the prior art, various wiring harnesses on the car body are mostly arranged in a direct bundling manner, and the main power line of the car and various other signal lines are placed together. When there are many wiring harnesses, it is difficult to effectively store the wiring harnesses by bundling, resulting in a messy wiring harness arrangement, inability to get power nearby, inconvenient installation and maintenance, and after the wiring harnesses are bundled, their own strength is not high, and their pressure resistance is poor. They are easily deformed or even broken after being squeezed. In addition, when the car power supply is short-circuited or other accidents occur, the heat of the power cord will cause the insulation layer of other signal lines to melt or burn, causing major safety accidents and posing great safety hazards.

[0031] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0032] like Figure 1-Figure 3 The annular automobile main power harness structure shown is used to connect the automobile battery 30 and supply power to the electrical devices on the vehicle through the low-voltage harness, and specifically comprises: a main line 10 arranged at least in an annular shape along the circumference of the bottom surface of the vehicle body, the main line 10 is a flat conductor, the main line has a narrow side surface and a wide side surface arranged oppositely, the surface of the wide side surface is extended and arranged in a conformal manner along the bottom surface of the vehicle body, and the main line 10 comprises an internal conductor 130 and an insulator 140 wrapping the conductor 130;

[0033] The height of the main line is less than the width of the flat conductor core. The surface corresponding to the height of the main line is the narrow side surface, and the surface corresponding to the width of the main line is the wide side surface. Any surface of the two opposite wide sides can be arranged in a manner that fits the vehicle body. The specific needs are set according to the bending direction of the main line. A plurality of branch lines 20 are electrically connected to the conductor 130 at one end. The branch lines 20 are arranged at intervals along the extension direction of the main line 10. The other end of at least one branch line 20 is connected to the battery 30, and the other ends of the other branch lines 20 are connected to the adapter component 20.

[0034] In a specific embodiment, a portion of the insulator 140 is removed from the connection position between the main line 10 and the branch line 20 to expose the conductor 130, the conductive portion of the branch line 20 is welded to the conductor 130, and then an insulating protective material is used to insulate and protect the connection position and a portion of the insulator 140.

[0035] The branch line 20 may be connected to an end of the main line 10 , or may be electrically connected to any position of the main line 10 .

[0036] Compared with the existing wiring harness design, this solution only uses one main line 10 as the power source, connects the adapter component 20 through the branch line 20 and supplies power to the electrical appliances of the entire vehicle, reducing the length of the wiring harness and the complexity of the wiring harness loop. The wiring is simple, and it only needs to be combined with the distribution of the adapter component 20 on the vehicle to ensure that the electrical devices can draw power nearby and power multiple electrical appliances.

[0037] At the same time, this solution also greatly reduces the difficulty of laying the automotive power harness structure, improves installation efficiency and saves costs.

[0038] like Figure 3 As shown, the main line 10 includes at least one upwardly arched arch structure 50 for avoiding the protrusion on the bottom surface of the vehicle body. The main line 10 is provided with a preset arch structure 50, which can cross obstacles on the vehicle body, reduce the difficulty of assembling the main line 10, and improve assembly efficiency.

[0039] Specifically, the arch structure 50 may be a bent structure formed by a portion of the main line 10 protruding toward a side opposite to the bottom surface of the vehicle body to which it is attached.

[0040] Specifically, the adapter component 20 includes a connector, a terminal, a splitter or a fuse box, and the low-voltage wiring harness is connected to obtain power through the adapter component 20.

[0041] Each adapter component 20 for supplying power to an electrical appliance has various forms, can match various forms of electrical appliances, and has good versatility.

[0042] In one embodiment, one end of the main line 10 starts from the trunk of the vehicle body, is arranged along the side of the bottom surface of the vehicle body, the side of the bottom surface of the instrument panel, and the other side of the bottom surface of the vehicle body, and finally returns to the trunk of the vehicle body. In another embodiment, both ends of the main line 10 can also be connected to the engine respectively.

[0043] The conductor 130 of the main line 10 can be specifically formed of aluminum, aluminum alloy, copper or copper alloy. The conductor 130 made of aluminum can reduce the cable cost while also reducing the weight of the cable, thereby contributing to cost reduction and energy conservation and emission reduction of automobiles. In addition, the conductor 130 is made of aluminum, and since its conductivity is not as good as that of copper, it is necessary to increase the cross-sectional area accordingly, that is, to increase the heat dissipation area, thereby better reducing the operating temperature.

[0044] In one embodiment, if Figure 2 As shown, the conductor 130 is a flat strip made of aluminum, which includes a solid flat strip 110 and at least one end of a flexible flat strip 120 arranged in the solid flat strip 110 , and both ends of the flexible flat strip 120 are respectively welded to two adjacent sections of the solid flat strip 110 .

[0045] When the main line 10 structure is installed, some installation locations have complex environments and require a flexible flat belt 120 with higher adaptability for transition, or some locations on the vehicle body have poor vibration conditions and require a flexible flat belt 120 to absorb vibration energy. In this case, the flexible flat belt 120 needs to be connected to the solid flat belt 110 to achieve electrical connection stability of the overall structure.

[0046] Furthermore, the flexible flat belt 120 includes a flat belt with multiple layers of thin sheets stacked on top of each other or a woven flat belt.

[0047] In one embodiment, a plurality of fixing parts are integrally injection-molded on the insulator 140 of the main line 10 toward the bottom surface of the vehicle body. The plurality of fixing parts are arranged at intervals along the extension line of the main line 10 and are installed in cooperation with the fixing structure of the bottom surface of the vehicle body to fix the main line 10 on the vehicle body.

[0048] In another embodiment, a plurality of mounting parts are integrally molded on the side of the insulator 140 facing away from the fixing part. The mounting parts are arranged at intervals along the main line 10, and the low-voltage wiring harness is at least partially fixed by cooperating with the mounting parts.

[0049] In one embodiment, at least one current sensor and / or at least one temperature sensor is disposed on the main line 10 to monitor the temperature of the main line 10 to ensure the stability of the electrical connection.

[0050] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
