Taking "A and/or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

With the development of new energy vehicles, more and more large square wire harnesses are used in the whole vehicle, which leads to the increasing weight of the whole vehicle wire harness and the required layout space. In addition, the existing wire harness is usually in a rod-shaped structure. When such a rod-shaped wire harness is installed on the vehicle, it often requires a lot of fasteners to fix it to the vehicle body. The addition of more fasteners will further increase the overall weight of the wire harness, which is not conducive to the lightweight design of the entire wire harness.

Based on this, the utility model proposes a power harness assembly, which sets the shape of the second power cord into a flat structure. In this way, when the power harness assembly is installed and fixed, it can fit the installation space more closely, thereby reducing the space occupied by the entire harness assembly. In addition, since the second power cord fits the installation space more closely, it can be well fixed with fewer locking structures, thereby further reducing the weight of the power harness assembly.

As shown in Figures 1 to 5, the power harness assembly includes:

A first power line 100;

A second power line 200, the second power line 200 is conductively connected to the first power line 100, and the second power line 200 is a flat structure; and

The locking structure 300 is disposed on the outer periphery of the second power cord 200 and is used to lock and fix the second power cord 200 .

In the technical solution adopted in this embodiment, the power harness assembly includes a first power cord 100 and a second power cord 200, and the first power cord 100 and the second power cord 200 are electrically connected; in order to facilitate the fixation of the second power cord 200, a locking structure 300 is also provided on the outer periphery of the second power cord 200, and the second power cord 200 can be installed in the installation space on the vehicle through the locking mechanism; in this solution, the shape of the second power cord 200 is set to a flat structure, so that when the power harness assembly is installed and fixed, on the one hand, the design of the flat structure can fit the installation space better and reduce the occupied space of the entire harness assembly; on the other hand, since the second power cord 200 fits the installation space more closely, only a few locking structures 300 are needed to fix it well, which further reduces the weight of the power harness assembly and makes the vehicle as a whole more in line with the lightweight design.

Specifically, the shape of the first power cord 100 is not specifically limited, for example, its cross section can be circular or rectangular, etc., with non-uniform height and width. In order to facilitate transportation and reduce transportation costs, the first power cord 100 is preferably an aluminum rod, which is a relatively soft rod-shaped structure made by casting, extrusion, etc.; for the second power cord 200, it is necessary to prefabricate it into a flat structure with greater rigidity before processing, for example, it can be an aluminum bar, that is, it is set to a wide, thin and flat structure. In this way, when the power harness assembly is fixed to the vehicle, this design makes the second power cord 200 very compatible with the installation space, and only a few locking structures 300 are needed to produce effective fixation, which effectively reduces the weight of the entire power harness assembly. In addition, since the second power cord 200 is in a rigid state after being prefabricated into a flat structure, it is not convenient to transport, while the first power cord 100 and the second power cord 200 have different processing technologies, are in a soft state, and are convenient to transport, which allows the entire power harness assembly to be folded during transportation, reducing the overall occupied space, and effectively reducing transportation costs. It should be noted that the shape of the locking structure 300 is not specifically limited, and it can be, for example, a buckle or a fixing ring, as long as it can fix the power harness assembly. It should be pointed out that in order to improve the safety of the power harness assembly, an insulating layer can be sprayed on the outer surface of the first power cord 100 and the second power cord 200.

Optionally, as shown in FIG5 , in an embodiment of the utility model, considering that a large current will be conducted in the second power cord 200 during use, in order to prevent the internal current from being too large and causing electromagnetic interference to other sensitive wiring harnesses in the surrounding area, the second power cord 200 in this embodiment includes a wiring harness body 210 and a shielding sleeve 220 sleeved on the outer periphery of the wiring harness body 210, wherein the wiring harness body 210 is conductively connected to the first power cord 100, and the wiring harness body 210 is a flat structure. Preferably, the shape of the shielding sleeve 220 is the same as that of the second power cord 200. It can be understood that the shape of the second power cord 200 is slightly smaller than the shape of the shielding sleeve 220, so that the second power cord 200 can be covered inside the shielding sleeve 220. Further, the material of the shielding sleeve 220 is preferably an aluminum foil sleeve. Of course, considering that the wiring harness body 210 is conductively connected to the first power cord 100, a large current will also be conducted inside it. In other embodiments, a similar shielding member can also be sleeved on the outer periphery of the first power cord 100.

Optionally, as shown in Figures 1, 2 and 5, in an embodiment of the utility model, in order to maximize the reduction of the space occupied by the second power cord 200 in the lateral direction, the wiring harness body 210 can be stacked with at least two layers and jointly arranged inside the shielding sleeve 220. In this way, the occupied volume of the entire power harness assembly is further reduced, and a specific installation design can be carried out according to the different installation spaces on the vehicle. When the vertical height of the installation space is insufficient, multiple wiring harness bodies 210 can be arranged in parallel in the lateral direction; however, when the lateral width of the installation space is insufficient, multiple wiring harness bodies 210 can be stacked vertically.

Optionally, as shown in FIG4 , in an embodiment of the utility model, the harness body 210 is welded to the first power line 100, for example, ultrasonic or plasma welding can be used; preferably, in order to prevent the internal conductive cores of the first power line 100 and the second power line 200 from being exposed to the air, causing oxidation and reducing the conductivity, after the harness body 210 and the first power line 100 are welded, a high-temperature exhaust treatment process can be added. In addition, in order to improve the sealing of the connection between the harness body 210 and the first power line 100, the power harness assembly also includes a sealing sleeve. It can be understood that the sealing sleeve needs to be sleeved on the outside of the connection between the harness body 210 and the first power line 100. Preferably, the sealing sleeve uses a heat shrink tube with glue; further, an adhesive layer can be provided on the inner wall of the sealing sleeve, and the harness body 210 and the first power line 100 can be well bonded and fixed by the adhesive layer, while ensuring the connection strength and having excellent sealing.

Optionally, in one embodiment of the utility model, in order to prevent accidental water ingress into the wiring harness body 210 and reduce its conductivity, the power harness assembly also includes a waterproof lip, one end of the waterproof lip is connected to the sealing sleeve, and the other end of the waterproof lip extends between the sealing sleeve and the wiring harness body 210 to elastically contact the wiring harness body 210, that is, a waterproof lip can be provided on the inner wall of the sealing sleeve, and the waterproof lip extends in the gap between the sealing sleeve and the wiring harness body 210, and the gap between the sealing sleeve and the wiring harness body 210 can be filled through the elastic contact between the waterproof lip and the wiring harness body 210.

Optionally, as shown in FIG5 , in one embodiment of the utility model, in order to prevent the wiring harness from being loosely fixed to the vehicle and causing abnormal noises such as shaking during the driving of the vehicle, the power harness assembly further includes a sound insulator 400. The first power cord 100 and the second power cord 200 may both be provided with a sound insulator 400 on their peripheries, or one of them may be provided with a sound insulator 400 alone. It should be noted that the sound insulator 400 may be made of sound insulation felt, wood fiber sound absorbing board, or polyester fiber sound absorbing board, etc. Preferably, the sound insulator 400 is made of flexible materials such as sound insulation sponge, so that it can be better arranged in a limited installation space.

Optionally, as shown in FIG5 , in one embodiment of the utility model, taking into account that the power harness assembly will generate more heat when in use, in order to dissipate the heat in a timely manner, a plurality of heat dissipation holes may be provided on the sound insulation member 400, and the heat dissipation holes are provided throughout the sound insulation member 400, so that the hot air flow on the surface of the first power cord 100 or the second power cord 200 can generate convection with the external gas through the heat dissipation holes, thereby better dissipating the heat.

Optionally, as shown in Figures 1 and 2, in one embodiment of the utility model, in order to make the power wiring harness assembly more compatible with the vehicle, during the processing of the second power cord 200, it will be bent and deformed at a predetermined installation position according to the layout shape, and multiple bending sections can be provided in the second power cord 200 according to actual needs.

Optionally, as shown in FIG. 1 to FIG. 3, in one embodiment of the utility model, in order to facilitate the transfer of the power harness assembly to the automobile, the two ends of the second power cord 200 are respectively provided with the first power cord 100, and the end of the first power cord 100 away from the second power cord 200 is provided with a conductive terminal 500, which can be electrically connected to the distribution box on the automobile through the conductive terminal 500. For example, one end of the power harness assembly can be electrically connected to the main distribution box through the conductive terminal 500, and the other end can be electrically connected to the junction box through the conductive terminal 500, so as to realize the layout of the power supply of the entire vehicle. It should be noted that the conductive terminal 500 can be a copper wire nose, or a conductive member such as a copper-aluminum terminal. Preferably, a fixing sleeve can also be provided between the conductive terminal 500 and the first power cord 100. The setting of the fixing sleeve can further improve the connection strength between the conductive terminal 500 and the first power cord 100; further, the fixing sleeve can be selected from a sleeve such as a heat shrink tube with glue.
