Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a novel wiring harness fixing bracket and a battery. Background Art

[0002] With the rapid development of the new energy industry, many consumers have reported that they are anxious about the driving range. This requires battery assembly plants (PACK plants) to meet high power demands as much as possible during the development process. However, many domestic OEMs started late in the development of new energy vehicles, and the entire package development process is to design the battery pack on the existing body, which greatly limits the outer envelope size of the battery pack. In order to meet the high power demand in a limited space, more battery cells need to be arranged, which indirectly squeezes the wiring space in the battery system in a limited space.

[0003] There are high-voltage and low-voltage harnesses in the battery system. The high-voltage harness is responsible for connecting all battery modules, and the low-voltage harness is mainly the acquisition and communication harness of the battery management system (BMS). The assembly and fixation of these harnesses in the battery system are particularly important. If the harness is not fixed firmly or reasonably, it may cause the harness to wear and cut, resulting in functional failure. Figures 1 to 3 As shown, the existing technology is to fix the wire harness 9 on the corresponding bracket of the end plate 6 of the battery module 7 through a cable tie 5, but only one cable tie 5 can be installed at the same fixing point, which causes all the wire harnesses 9 to be gathered together, squeezed and heat gathered between each other, and sometimes high and low voltage wire harnesses are bundled together, which not only takes up a large space but is also very unsafe.

[0043] More specifically, the wiring troughs 4 are distributed in parallel along the first direction, and the leads of each battery module 7 are also arranged in the first direction, ensuring that the wiring harness 9 is evenly distributed and fixed in a limited space to prevent heat accumulation;

[0044] More specifically, the utility model selects appropriate materials and processing techniques to manufacture the mounting plate 2 and the harness slot 3 according to actual needs, such as metal or plastic, and the prepared harness fixing bracket 1 itself meets relevant strength requirements and regulatory requirements.

[0045] Specifically, the wire harness fixing bracket 1 of the utility model adopts PC+ABS injection molding process, the material is cheap, the structure is reliable, and it has passed the relevant DV verification experiment. The thickness of the mounting plate 2 is 1.5mm, and a tie hole 21 is reserved in the design to facilitate workers to fix the wire harness 9 during assembly. At the same time, a slot portion 31 and a wire management slot portion 32 are also added to facilitate the combing and fixing of the wire harness 9 during assembly, and to prevent the wire harness 9 from being misplaced. The wire harness 9 is arranged and fixed by fixing the wire harness fixing bracket 1 to the end plate 6 through the buckle 22. It only needs to add a buckle hole 61 on the end plate 6 for installation, and the overall assembly is simple.

[0046] In a preferred embodiment, the first direction is a direction perpendicular to the distribution direction of the battery modules 7 .

[0047] Specifically, a plurality of battery modules 7 are arranged along a set direction, and the side edges of the end plates 6 on the battery modules 7 are adjacent in sequence along the set direction; a wire harness fixing bracket 1 is provided on each end plate 6, and the wire harness fixing bracket 1 is also arranged along the set direction of the battery modules 7; the wire harness 9 led out of the battery module 7 arranged at the Nth position in the set direction is limited on the Nth wiring groove 4 of the wire harness fixing bracket 1 arranged from the Nth position to the last position;

At this point, the wiring harness 9 fixing process is completed, and the same goes for the rest of the wiring harnesses 9 of the battery modules 7. Through this structural array method, the wiring harnesses 9 of multiple battery modules 7 can be fixed.

[0065] Specifically, there are four buckles 22 , which are respectively located at the four corners of the mounting plate 2 , and the buckle holes 61 are disposed at positions corresponding to the buckles 22 .

[0076] The wiring harness 9 led out from the second battery module 7 is first limited in the second wiring groove 4 of the wiring harness fixing bracket 1 connected to the second battery module 7, and then the wiring harness 9 is limited in the second wiring groove 4 of the 3rd to 9th wiring harness fixing brackets 1 along the arrangement direction of the battery modules 7 starting from the second wiring harness fixing bracket 1; and so on, the wiring harness 9 led out from the ninth battery module 7 is limited in the ninth wiring groove 4 of the ninth wiring harness fixing bracket 1.
