Description

TECHNICAL FIELD

[0001] The application relates to the technical field of new energy battery modules, in particular to an integrated busbar structure. BACKGROUND

[0002] With the rapid development of the new energy market, the capacity requirements of power and energy storage batteries and the space occupancy rate requirements of PACK packages are also increasingly high. In order to have a strong competitive advantage in cost, the PACK package (battery assembly) in the prior art generally adopts an external wiring harness to be plugged into the connector end of a CCS (integrated collection busbar scheme) for low-voltage signal output. The external wiring harness needs to be fixed by using an independent fixing bracket or an airplane buckle combined with the frame of the PACK package. This has a large space occupancy.

[0003] Based on the special fixing mode of this scheme, the external wiring harness generally needs to be specially customized and installed with an airplane buckle. When the pre-installed position of the airplane buckle is inaccurate or the shape of the formed wiring harness deviates, the airplane buckle cannot be installed into the positioning hole. This is relatively cumbersome and difficult for actual assembly. CONTENT OF THE UTILITY MODEL

[0004] The technical problem to be solved by the application is to optimize the existing wiring harness fixing bracket, thereby improving the adaptability of the wiring harness and the fixing bracket and simplifying the assembly process.

[0005] In order to solve the above problems, the application provides an integrated busbar structure, which comprises an integrated busbar, an integrated slave plate and a wiring harness fixing bracket. The integrated slave plate is fixed to the integrated busbar. The wiring harness fixing bracket comprises a bottom plate and a fixing part. The fixing part is integrally formed on one side of the bottom plate. The fixing part penetrates the integrated busbar and is fixed to the integrated busbar. The fixing part is provided with a fixing groove for accommodating a wiring harness.

[0006] Preferably, the fixing groove is in a U shape.

[0007] Preferably, the bottom plate is integrally formed with a hot riveting part on one side. The hot riveting parts are respectively located on both sides of the fixing part. The hot riveting parts penetrate and are hot riveted to the integrated busbar.

The aluminum bars and the flexible circuit boards are adjacently arranged along the length direction of the integrated busbar. The aluminum bars are respectively located on both sides of the flexible circuit board. The nickel sheet is connected to the aluminum bars and the flexible circuit board.

[0010] Preferably, the integrated busbar is further provided with a first fixing plate, the first fixing plate is arranged between the integrated busbar and the integrated slave plate, and the first fixing plate is used for fixing the integrated slave plate.

[0011] Preferably, the integrated busbar is further provided with a reinforcing plate, the reinforcing plate is fixed to a side of the integrated busbar away from the integrated slave plate, and the reinforcing plate penetrates the integrated busbar, the first fixing plate and the integrated slave plate in sequence.

[0012] Preferably, the integrated busbar structure further comprises a second fixing plate and a temperature sensing collector, the second fixing plate is arranged on one side of the integrated busbar, and the second fixing plate is used for fixing the temperature sensing collector.

[0013] Compared with the prior art, the present application has at least one of the following beneficial technical effects:

[0014] The wire harness can be one or integrated by multiple wires, and one end of the wire harness is fixedly connected to the integrated slave plate or other structure. When the wire harness fixing frame is used, the wire harness fixing frame is first fixedly installed on the integrated busbar, the movable end of the wire harness penetrates and is limited in the fixing groove of the fixing portion, the signals collected by the integrated busbar are output through the integrated slave plate, and the wire harness is directly clamped and fixed through the wire harness fixing frame. In this way, the wire harness does not need to be specially customized in shape, and is fixed by using the fixing portion of the wire harness fixing frame during assembly, without the need to increase additional positioning parts.

The integrated slave plate 2 is fixed to one side of the integrated busbar 1, and the plurality of wire harness fixing frames 3 are respectively fixed to the integrated busbar 1.

[0031] Specifically, the integrated busbar 1 is provided with a plurality of mounting holes 11, and the number of the mounting holes 11 corresponds to the number of the wire harness fixing frames 3. The wire harness fixing frame 3 comprises a bottom plate 31 and a fixing portion 32, the fixing portion 32 is integrally formed on one side of the bottom plate 31, the fixing portion 32 penetrates the mounting hole 11 and is fixed to the integrated busbar 1, and the fixing portion 32 is provided with a fixing groove 321 for accommodating the wire harness along the horizontal direction.

[0032] Here, the wire harness can be one or integrated by a plurality of wires, and one end of the wire harness is fixedly connected to the integrated slave plate 2 or other structures. When the wire harness fixing frame 3 is used, the wire harness fixing frame 3 is first fixedly installed on the integrated busbar 1, the movable end of the wire harness penetrates and is limited in the fixing groove 321 of the fixing portion 32, the signals collected by the integrated busbar 1 are output through the integrated slave plate 2, and the wire harness is directly clamped and fixed through the wire harness fixing frame 3. For this, the wire harness does not need to be specially customized in shape, and the fixing portion 32 of the wire harness fixing frame 3 is used for fixing during assembly, without the need to increase additional positioning parts.

[0033] Compared with the conventional fixing mode of the wire harness, the use of the wire harness fixing frame 3 can avoid the problems that the wire harness needs to be specially made and the wire harness is not positioned during assembly, reduce the manufacturing and assembly time, increase the output rate, and improve the reliability of the product after assembly. Therefore, the embodiment of the present application optimizes the existing wire harness fixing frame, thereby improving the adaptability of the wire harness and the fixing frame, simplifying the assembly process, and reducing the space occupation of the wire harness to the PACK package.
