Detailed ways

The technical solution of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described implementation methods are only part of the implementation methods of the present application, rather than all the implementation methods. Based on the implementation methods in the present application, all other implementation methods obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

Please refer to FIG. 1 , which is a schematic structural diagram of a battery module provided in one embodiment of the present application.

In this embodiment, the battery module 1000 includes a wiring harness isolation plate assembly 100, a battery cell group 300, a first end cap 500, a second end cap 700 and a fastener 900. The wiring harness isolation plate assembly 100 is disposed on the battery cell group 300, and the wiring harness isolation plate assembly 100 is used to connect to an external load. The battery cell group 300 is used to provide power, and the wiring harness isolation plate assembly 100 is electrically connected to the battery cell group 300 to introduce the electric energy of the battery cell group 300 into the external load.

It can be understood that the external load includes a power structure (motor), a lighting structure (lamp), etc., and this application does not impose any limitation on this.

As shown in FIG1 , the battery cell group 300 includes a plurality of battery cells 301, and the plurality of battery cells 301 are sequentially connected in series to form the battery cell group 300. The battery cells 301 are provided with electrical connection terminals (not shown in the figure), and the wiring harness isolation plate assembly 100 is used to connect with the electrical connection terminals of the plurality of battery cells 301, so as to sequentially connect the plurality of battery cells 301 in series, and then introduce the electric energy of the battery cells 301 into the external load. The first end cap 500 is provided at one end of the battery cell group 300 in the length direction, and the second end cap 700 is provided at the other end of the battery cell group 300 in the length direction. The fastener 900 is fixedly connected between the first end cap 500 and the second end cap 700, so that the first end cap 500 and the second end cap 700 abut and compress the plurality of battery cells 301 in the length direction, thereby making the plurality of battery cells 301 arranged more closely in the length direction, which is conducive to improving the overall stability of the battery cell group 300. The length direction is the direction of the length of the wiring harness isolation plate assembly 100 (the length direction of the battery cell group 300 formed by sequentially arranging the plurality of battery cells 301 ).

It is understandable that in other embodiments, among the multiple battery cells 301, some of the battery cells 301 are connected in series, and another part of the battery cells 301 are connected in parallel to form a battery cell group 300, and the present application does not limit this. Among them, the wiring harness isolation plate assembly 100 is applicable to the part of the battery cells 301 connected in series.

Specifically, as shown in FIG1 , the battery cell group 300 includes twelve battery cells 301 arranged in sequence along the length direction, and the first end cover 500 and the second end cover 700 clamp and fix the twelve battery cells 301 as a whole through the fastener 900. Among them, the fastener 900 can be a steel tie, which is sleeved outside the first end cover 500 and the second end cover 700. By adjusting the steel tie, the first end cover 500 and the second end cover 700 can move toward each other, thereby pressing and fixing the twelve battery cells 301 as a whole, which is beneficial to improving the stability of the battery cell group 300 and the battery module 1000. In this embodiment, the number of steel ties includes but is not limited to one, two, three, etc.

It can be understood that in other embodiments, considering the different loads connected to the wiring harness isolation plate assembly 100, the battery cell group 300 can also include eight battery cells 301, ten battery cells 301, fourteen battery cells 301, sixteen battery cells 301 and other numbers of battery cells 301 arranged in sequence along the length direction, and the present application does not impose any restrictions on this.

Please refer to FIG. 1 and FIG. 2 , FIG. 2 is a schematic diagram of the assembly structure of a wiring harness isolation plate assembly provided in one embodiment of the present application.

In this embodiment, the wire harness isolation plate assembly 100 includes a plurality of electrical connectors 10 , an isolation plate body 30 and a parameter acquisition assembly 50 .

The plurality of electrical connectors 10 are used to electrically connect to the cell group 300 of the battery module 1000 , and the plurality of electrical connectors 10 are arranged according to the layout of the cells 301 of the cell group 300 to connect the plurality of cells 301 of the cell group 300 in series.

The isolating plate body 30 extends in the length direction, and includes a plurality of isolating sub-plates 30a, which are arranged according to the layout of the plurality of electrical connectors 10, and the plurality of isolating sub-plates 30a are detachably connected in sequence along the length direction of the isolating plate body 30. The plurality of electrical connectors 10 are respectively connected to the plurality of isolating sub-plates 30a, so that the plurality of isolating sub-plates 30a are arranged according to the layout of the electrical connectors 10.

The parameter acquisition component 50 is disposed on a plurality of sequentially connected isolation sub-boards 30a and is electrically connected to the electrical connector 10. The assembly 50 is used to obtain the temperature of the battery cell 301 of the battery module 1000 and/or obtain the voltage of the battery cell 301 of the battery module 1000 to achieve a temperature detection function and/or a conductive function.

In the wiring harness isolation plate assembly 100 provided in this embodiment, the electrical connector 10 is electrically connected to the battery cell 301 of the battery module 1000 to connect multiple battery cells 301 in series. By connecting multiple isolation sub-plates 30a detachably in sequence along the length direction, it is beneficial to reduce the volume size of a single isolation sub-plate 30a, and the difficulty of opening the mold of the isolation sub-plate 30a can be reduced, thereby reducing the manufacturing cost of the isolation plate body 30 and the wiring harness isolation plate assembly 100. Moreover, the isolation plate body 30 includes multiple isolation sub-plates 30a that are detachably connected along the length direction. Compared with the integrated isolation plate body 30, the design of the separated isolation plate body 30 has lower requirements on the stacking accuracy of the battery cell group 300 in the battery module 1000, which can reduce the assembly difficulty of the battery module 1000 and is beneficial to improve the efficiency of the wiring harness isolation plate assembly 100 installed in the battery module 1000. Through multiple isolating sub-plates 30a, the layout can be divided according to the positions of multiple electrical connectors 10, and each isolating sub-plate 30a is provided with at least one electrical connector 10 on both sides along the width direction, and the electrical connector 10 is connected to the isolating sub-plate 30a, so that the layout of the multiple electrical connectors 10 is more stable, which is conducive to reducing the movement of the electrical connector 10 relative to the battery cell 301, and can improve the stability of the battery module 1000. The parameter acquisition component 50 is arranged on the side of the multiple isolating plate bodies 30 away from the battery cell group 300, and the parameter acquisition component 50 is connected to the electrical connector 10 respectively, so that the layout of the parameter acquisition component 50 in the wiring harness isolation plate assembly 100 is more compact, which is convenient for adjusting and maintaining the wiring harness isolation plate assembly 100.

Furthermore, the orthographic projection of the electrical connector 10 connected to the same isolating sub-plate 30a along the width direction on the isolating sub-plate 30a is completely located on the isolating sub-plate 30a, so that the electrical connector 10 does not need to cross the adjacent isolating sub-plate 30a to connect to the isolating sub-plate 30a. In the length direction, two adjacent electrical connectors 10 on two adjacent isolating sub-plates 30a are arranged at intervals, and in the width direction, two adjacent electrical connectors 10 connected to the same isolating plate body 30 are arranged in a staggered manner.

The wire harness isolation plate assembly 100 provided in this embodiment is provided with two adjacent electrical connectors 10 on two adjacent isolation sub-plates 30a arranged at intervals, so that the electrical connector 10 does not need to be installed across the isolation sub-plates 30a, which is conducive to reducing the assembly difficulty of the wire harness isolation plate assembly 100, and further improving the assembly efficiency of the wire harness isolation plate assembly 100. The two adjacent electrical connectors 10 connected to the same isolation plate body 30 are staggered in the width direction, so that the electrical connector 10 can electrically connect the multiple battery cells 301 of the battery module 1000 into a whole.

Specifically, referring to FIG. 1 and FIG. 2 , taking the battery cell group 300 including twelve battery cells 301 as an example, the wiring harness isolation plate assembly 100 includes thirteen electrical connectors 10, and the thirteen electrical connectors 10 are used to sequentially connect the electrical connection terminals of the twelve battery cells 301 in series. It can be understood that when the battery cell group 300 includes ten battery cells 301, the wiring harness isolation plate assembly 100 may include eleven electrical connectors 10. Similarly, when the battery cell group 300 includes fourteen battery cells 301, the wiring harness isolation plate assembly 100 may include fifteen electrical connectors 10.

More specifically, as shown in Figure 1, the thirteen electrical connectors 10 include a first electrical connector 11, ten second electrical connectors 13 and a third electrical connector 15, the first electrical connector 11 is fixed to the first end cover 500 and is electrically connected to the negative electrical connection terminal of a battery cell 301 near the first end cover 500, the eleven second electrical connectors 13 connect the twelve battery cells 301 in series in sequence, and the third electrical connector 15 is fixed to the second end cover 700 and is electrically connected to the positive electrical connection terminal of a battery cell 301 near the second end cover 700.

Specifically, taking the example of multiple electrical connectors 10 including a first electrical connector 11, ten second electrical connectors 13 and a third electrical connector 15, the isolation plate main body 30 includes six isolation sub-plates 30a, and the six isolation sub-plates 30a are detachably connected in sequence according to the layout of thirteen electrical connectors 10, and the six isolation sub-plates 30a are detachably connected to the thirteen electrical connectors 10.

Furthermore, any two adjacent isolating sub-plates 30a among the six isolating sub-plates 30a can move relative to each other along the length direction, so that the isolating plate body 30 can be lengthened or shortened along the length direction. It can be understood that in other embodiments, any two adjacent isolating sub-plates 30a among the six isolating sub-plates 30a can move relative to each other along the length direction. There is no restriction on this application.

The wiring harness isolation plate assembly 100 provided in this embodiment can generate relative movement along the length direction between any two adjacent isolation sub-plates 30a, so that the isolation plate body 30 can be lengthened or shortened along the length direction, and thus can be compatible with the stacking tolerance of the battery cells 301 of the battery module 1000 in the length direction, which is beneficial to improving the assembly efficiency of the wiring harness isolation plate assembly 100.

Furthermore, the range in which the isolation plate body 30 and the wiring harness isolation plate assembly 100 can be stretched along the length direction is [0.2mm, 1mm], and the range in which the isolation plate body 30 and the wiring harness isolation plate assembly 100 can be shortened along the length direction is [0.2mm, 1mm].

The wiring harness isolation plate assembly 100 provided in this embodiment can prevent the distance between the battery cells 301 in the battery cell group 300 from being too large by limiting the length that the wiring harness isolation plate assembly 100 can be stretched or shortened in the length direction, so that the wiring harness isolation plate assembly 100 can be installed on the battery module 1000 with better stability.

The plurality of isolating sub-plates 30a include a first isolating sub-plate 31, at least one second isolating sub-plate 33 and a third isolating sub-plate 35 which are detachably connected in sequence along the length direction. The shapes of the first isolating sub-plate 31, the second isolating sub-plate 33 and the third isolating sub-plate 35 are different from each other.

The wiring harness isolation plate assembly 100 provided in the embodiment of the present application includes a first isolation plate 31, at least a second isolation plate 33 and a third isolation plate 35 which are detachably connected in sequence along the length direction through a plurality of isolation sub-plates 30a, and the electrical connector 10 and the isolation sub-plate 30a are detachably connected, so that the plurality of isolation sub-plates 30a can be divided and laid out according to the positions of the plurality of electrical connectors 10, which is conducive to reducing the volume size of a single isolation sub-plate 30a, and can reduce the difficulty of opening a mold for a single isolation sub-plate 30a, thereby reducing the manufacturing cost of the wiring harness isolation plate assembly 100. Moreover, the shapes of the first isolation sub-plate 31, the second isolation sub-plate 33 and the third isolation sub-plate 35 are different from each other, so that the isolation plate body 30 has a fool-proof effect during assembly, which is conducive to improving the assembly efficiency of the isolation plate body 30.

Specifically, the wire harness isolating plate assembly 100 provided in this embodiment includes six isolating sub-plates 30a, including a first isolating sub-plate 31, four second isolating sub-plates 33 and a third isolating sub-plate 35, which are detachably connected in sequence along the length direction. The first isolating sub-plate 31, the second isolating sub-plate 33 and the third isolating sub-plate 35 are detachably connected in sequence through the detachable connection between the electrical connector 10 and the isolating sub-plate 30a, so that the isolating plate body 30 can be divided and laid out according to the positions of the multiple electrical connectors 10, which is conducive to reducing the volume size of a single isolating sub-plate 30a, and can reduce the difficulty of opening the mold of a single isolating sub-plate 30a, thereby reducing the manufacturing cost of the wire harness isolating plate assembly 100. Among them, the shapes of the first isolating sub-plate 31, the second isolating sub-plate 33 and the third isolating sub-plate 35 are different from each other, and the shapes of the four second isolating sub-plates 33 are the same, so that the isolating plate body 30 has a fool-proof effect during assembly, which is conducive to improving the assembly efficiency of the isolating plate body 30.

It can be understood that the fifth sub-section 351 and the sixth sub-section 352 can be integrally formed.
