It is to be understood that the described embodiments are merely a few embodiments of the present application and not all embodiments.

As shown in fig. 1 to 12, embodiments of the present application provide a wire harness assembly that may be mounted on a housing of a battery, or other device, wherein the wire harness assembly may include a fixing assembly 100 and a wire harness 200.

The fixing assembly 100 includes a first structural member 110, a second structural member 120, and a third structural member 130, wherein the first structural member 110, the third structural member 130, and the second structural member 120 are sequentially stacked, for example, the third structural member 130 is located between the first structural member 110 and the second structural member 120.

The first structural member 110 is provided with a first through hole 111, wherein the first through hole 111 facilitates the wire harness 200 to pass through and the connection between the wire harness 200 and the first structural member 110 to be realized.

It should be noted that, in the present embodiment, the diameter of the first through hole 111 is larger than the diameter of the wire harness 200, for example, the difference between the diameter of the first through hole 111 and the diameter of the wire harness 200 is larger than 2%, so that the wire harness 200 can be prevented from being damaged during the process of threading the wire harness 200.

In addition, the number of the first through holes 111 may be multiple, wherein the number of the first through holes 111 corresponds to the number of the wire harnesses 200, and when the number of the first through holes 111 is multiple, the diameters of the multiple first through holes 111 may be the same or different, and may specifically be set according to the size of the diameter of the wire harness 200, for example, the number of the first through holes 111 may be seven, and taking the orientation shown in fig. 3 and 4 as an example, from left to right, the diameters of the first through hole and the seventh first through hole are the same and are larger than the rest of the first through holes.

In the present embodiment, the entire area of the first structural member 110 may be flat, for example, the first structural member 110 may include a flat plate-shaped structure, wherein the shape of the flat plate-shaped structure may be a regular shape, for example, the shape of the flat plate-shaped structure is a rectangle, and the flat plate-shaped structure has rounded corners, so as to reduce the risk of scratching an operator or the case of the battery. In the present embodiment, the first structural member 110 may be understood as a flat plate-like structure having substantially equal thickness.

For example, the first structural member 110 includes a first region having a flat shape, where the flat shape refers to that the surface of the first structural member 110 is a plane and is not uneven.

The second structural member 120 is disposed at one side of the first structural member 110 and detachably connected to the first structural member 110, wherein the entire area of the first structural member 110 is flat, for example, the second structural member 120 includes a flat plate-shaped structure, wherein the shape of the flat plate-shaped structure may be a regular shape, for example, the shape of the flat plate-shaped structure is a rectangle, and the flat plate-shaped structure has round corners to reduce the risk of scratching an operator or the housing of the battery. In the present embodiment, the second structural member 120 may be understood as a flat plate-like structure having substantially equal thickness.

A portion of the second structure 120 may be flat, for example, the second structure 120 may include a second area that is flat.

In the present embodiment, the first structural member 110 and the second structural member 120 are used to apply a force to the third structural member 130 to elastically deform the first portion of the third structural member 130 toward the center of the third through hole 131 to press the outer circumferential surface of the wire harness 200.

In the present embodiment, the diameter of the third through hole 131 is larger than the diameter of the wire harness 200, for example, the difference between the diameter of the third through hole 131 and the diameter of the wire harness 200 is larger than 1%, so as to facilitate smooth penetration of the wire harness 200.

In some embodiments, as shown in fig. 5, a boss 114 may be further disposed on a side of the first structural member 110 facing away from the second structural member 120, and the boss 114 may be used to enhance the strength of the first structural member 110.

In some embodiments, the first structure member 110 is detachably connected to the second structure member 120, wherein the detachable connection between the second structure member 120 and the first structure member 110 can be achieved in various manners, for example, the second structure member 120 can be connected to the first structure member 110 by screws, or can be clamped, so as to facilitate the detachment and installation of the fixing assembly 100.

Illustratively, as shown in fig. 5 and 6, the second structural member 120 is provided with a first hole 122, and a side of the first structural member 110 facing the second structural member 120 is provided with a boss 112, and the boss 112 is connected in the first hole 122 after passing through the elastic member, for example, the boss 112 is connected in the second hole 123 after passing through the third hole 132.

The convex column 112 located in the first hole 122 may be in interference fit with the first hole 122, and the convex column 112 and the first hole 122 are detachably connected by using the abutting force between the outer circumferential surface of the convex column 112 and the inner wall of the first hole 122.

In this embodiment, the number of the protruding columns 112 may be two, the two protruding columns 112 are symmetrically disposed with respect to the central axis of the first structural member 110, and a gap is formed between the protruding columns 112 and the edge of the first structural member 110, so that the protruding columns 112 are close to the first through holes 111, which not only can transmit the acting force to the first holes 122 in time, improve the sealing effect of the elastic member, but also can slow down the sealing failure at the edge positions of the first structural member 110 and the second structural member 120.

It should be noted that the number of the convex pillars 112 is not limited to two, and other options are also possible, for example, the number of the convex pillars 112 is three or four.

As shown in fig. 9, 11, and 12, when the elastic member is subjected to a force, for example, the elastic member is subjected to a pressing force perpendicular to the first structural member 110, or a pushing force parallel to the first structural member 110, the elastic member is subjected to a force to elastically deform toward the center of the third through hole 131, the elastic member fills the gap between the wire harness 200 and the third through hole 131 and tightly abuts against the outer circumferential surface of the wire harness 200, and moisture is restricted from entering the case of the battery through the gap between the wire harness 200 and the third through hole 131, so that the safety performance of the battery is improved.

It should be noted that, in the present embodiment, the acting force applied to the elastic member may also be applied by a device used in cooperation with the wire harness assembly, for example, the wire harness assembly may be fixed to the housing of the battery, and during the process of mounting the wire harness assembly to the housing of the battery, the surface of the housing may apply a pressing force perpendicular to the first structural member to the elastic member, which may cause the elastic pressing portion to elastically deform toward the center of the third through hole 131.

In some embodiments, as shown in fig. 7, the end of the post 112 distal from the first structure 110 has a groove 1123, and the end of the post 112 that connects within the first hole 122 has a groove 1123.

At least one end of the groove 1123 penetrates the boss 112 in a radial direction of the boss 112, for example, one end of the groove 1123 may penetrate the boss 112 in the radial direction of the boss 112; for another example, both ends of the groove 1123 may penetrate through the boss 112 along a radial direction of the boss 112 to separate an end of the boss 112 into two independent portions, so that a diameter of the first hole 122 may be slightly smaller than a diameter of the boss 112, and when the boss 112 is engaged in the first hole 122, the groove 1123 provides a space for deformation of the boss 112 to ensure sealing between the boss 112 and the first hole 122.

Further, the number of the grooves 1123 may be multiple, the grooves 1123 are disposed at intervals around the axis direction of the boss 112, the ends of the grooves 1123 close to the axis of the boss 112 are communicated, and the intersection point of the ends of the grooves is located on the axis of the boss 112.

When the number of the grooves 1123 is two, the radial directions of the two grooves 1123 may be on the same straight line or on different straight lines, so as to divide the end portion of the convex pillar 112 into two parts.

When the number of the grooves 1123 is three, the three grooves 1123 divide the end of the stud 112 into three parts.

When the number of the grooves 1123 is four, the four grooves 1123 divide the end of the stud 112 into four parts.

In the embodiment, the grooves are arranged in a plurality of ways, so that more deformation spaces can be provided for the end of the convex column 112, and the sealing property between the convex column 112 and the first hole 122 is ensured.
