The bending plate 215 is provided at one end of the connecting plate 211 that is higher than the upper surface of the battery management module 1. The wire harness body 5 is tied to the bending plate 215. The identical structure of the first expansion plate 21 and the second expansion plate 22 can ensure that the different wire harness bodies 5 have the same direction, thereby avoiding interference between the wire harness body 5 and the top cover of the housing 4. The connecting plate 211 is used to fix the position of the first expansion plate 21 and to support the bending plate 215. The bending plate 215 is used to tie the wire harness body 5 and to provide accommodating space for the wire harness body 5. The bending plate 215 is provided at one end of the connecting plate 211 that is higher than the upper surface of the battery management module 1 to increase the height of the wire harness body 5 and to clarify the direction of the wire harness body 5.

Figure 6 As shown, in some embodiments, the bending plate 215 is an L-shaped bending plate 215; the bending part of the L-shaped bending plate 215 provides a space for the wire harness body 5 and defines the direction of the wire harness body 5.

[0033] In some embodiments, the difference between the end of the bending plate 215 away from the connecting plate 211 and the upper surface of the battery management module 1 is 15-25mm. The difference of 15-25mm provides binding space for the binding harness body 5, clarifies the direction of the harness body 5, and avoids interference between the harness body 5 and the top cover of the box 4.

[0034] In some embodiments, the difference between the end of the bending plate 215 away from the battery management module 1 and the upper surface of the battery management module 1 is 20mm; the 20mm difference provides binding space for the binding harness body 5, clarifies the direction of the harness body 5, and avoids interference between the harness body 5 and the top cover of the box 4.

[0035] In some embodiments, the bending plate 215 is provided with a plurality of binding holes 216 at the part away from the connecting plate 211, and the wire harness body 5 is bound to the binding holes 216; the plurality of binding holes 216 are used to bind the wire harness body 5, thereby restricting the position and direction of the wire harness body 5.

Both sides of the support plate 32 are provided with mounting plates 33 facing the battery management module 1. The mounting plates 33 are connected to the battery management module 1 by fasteners. The directions of the folded ear 31 and the fixing plate 34 are opposite to the direction of the mounting plate 33. The folded ear 31 is used to bind the wire harness body 5 and guide the direction of the wire harness body 5. The support plate 32 not only supports the main body 3, but also connects the folded ear 31 and the fixing plate 34. The mounting plate 33 is used to connect the battery management module 1 and the expansion component 2.

[0042] In some embodiments, the support plate 32 is provided with a reinforcing groove 321 near the folded lug 31; the reinforcing groove 321 is used to strengthen the support plate 32.

[0043] In some embodiments, the reinforcing groove 321 is a U-shaped reinforcing groove 321; the U-shaped reinforcing groove 321 is used to strengthen the support plate 32.

[0044] Figure 4 A schematic diagram showing the connection between nut 332 and mounting plate 33 is provided. Figure 4 As shown, in some embodiments, the mounting plate 33 is provided with a through hole 331, and a nut 332 is welded to the mounting plate 33 at the position of the through hole 331 to facilitate connection with fasteners.

[0045] Specifically, the mounting plate 33 is provided with a nut 332 on the side facing the reinforcing groove 321.

[0046] In some embodiments, the upper surface of the folded ear 31 is higher than the upper surface of the battery management module 1, which is used to increase the height of the wire harness body 5 and clarify the orientation of the wire harness body 5.

[0047] In some embodiments, the difference between the upper surface of the folded ear 31 and the upper surface of the battery management module 1 is 15-30mm; the difference of 15-30mm provides binding space for the binding harness body 5, clarifies the direction of the harness body 5, and avoids interference between the harness body 5 and the top cover of the housing 4.

[0048] In some embodiments, the difference between the upper surface of the folded ear 31 and the upper surface of the battery management module 1 is 25mm; the 25mm difference provides binding space for the binding harness body 5, clarifies the direction of the harness body 5, and avoids interference between the harness body 5 and the top cover of the housing 4.

[0049] In some embodiments, the folded ear 31 is provided with a mounting hole 311 for binding the wire harness body 5 and defining the direction of the wire harness body 5.

[0050] In some embodiments, the end of the main body 3 away from the wire harness body 5 is connected to a housing 4, which not only restricts the position of the main body 3, but also serves to support the main body 3.

[0051] In some embodiments, the fixing plate 34 is connected to the housing 4; the connection between the fixing plate 34 and the housing 4 can restrict the position of the main body 3 and also provide support for the main body 3.

[0052] In some embodiments, the fixing plate 34 is provided with fixing holes 341 for connecting the housing 4.

[0053] Specifically, fasteners can be, but are not limited to, bolts. Bolts are existing technology and will not be discussed further here.

[0054] Specifically, battery management module 1 is a battery management system.

[0055] The working principle of a wire harness fixing bracket is as follows:

[0056] By restricting the position of the wire harness body 5 and guiding its direction, interference between the wire harness body 5 and the box cover is avoided, as well as safety accidents such as damage to the wire harness body 5, short circuits, and fires. Specifically, the first expansion plate 21 is first attached to the power management module, then the main body 3 is placed at both ends of the power management module. Fasteners are then used to sequentially connect the first expansion plate 21, the power management module, and the connecting plate 211 of the main body 3. Fasteners are then used to sequentially connect the second expansion plate 22, the power management module, and the connecting plate 211 of the main body 3. Finally, fasteners are used to connect the fixing plate 34 of the main body 3 to the box 4. After installation, straighten the wire harness body 5 and select the guiding direction of the wire harness body 5 according to the actual situation, that is, select the main body 3 at one end of the power management module or the main body 3 at both ends. After determining the guiding direction of the wire harness body 5, tie the wire harness body 5 to the first expansion plate 21, the second expansion plate 22 and the selected main body 3 in sequence with cable ties 6. This restricts the direction of the wire harness body 5, avoids interference between the wire harness body 5 and the box cover, and also avoids safety accidents such as damage to the wire harness body 5, short circuit and fire.
