The mounting surface 111 is provided with a first avoidance hole 112, and the first avoidance hole 112 penetrates through the wire harness bracket 110 along the thickness direction of the wire harness bracket 110, that is, the first avoidance hole 112 is a through hole. The first avoidance hole 112 is used for avoiding an electrode of the battery cell 200 in the battery module 10, that is, when the wire harness bracket 110 is installed above the battery cell 200 of the battery module 10, the first avoidance hole 112 corresponds to the electrode of the battery cell 200, and the electrode of the battery cell 200 passes through the corresponding first avoidance hole 112, so that the connection assembly 120 is electrically connected with the battery cell 200.

As shown in fig. 2 and 4, a first limiting member 114 is protruding on the mounting surface 111 near the first avoidance hole 112, the first limiting member 114 has elasticity, a first limiting space 1142 is formed on the first limiting member 114, and the first limiting space 1142 is used for mounting the acquisition harness 130. That is, when the collection harness 130 is connected to the connection assembly 120, the collection harness 130 is first mounted on the mounting surface 111 of the harness bracket 110, and the collection harness 130 is fixed in the first limiting space 1142 on the first limiting member 114, and meanwhile, the first limiting member 114 has elasticity, so that the first limiting member 114 can limit the degree of freedom of the collection harness 130 by using plastic deformation of itself.

It should be noted that, because the collecting wire harness 130 is electrically connected with the connecting component 120, the portion of the collecting wire harness 130 near the connecting component 120 is bent, stress concentration is easy to be generated at the bending position of the collecting wire harness 130, and the connecting component 120 is used for being electrically connected with the electrode of the electric core 200 in the battery module 10, the setting position of the collecting wire harness is corresponding to the first avoiding hole 112, the first limiting piece 114 is convexly arranged at the position near the first avoiding hole 112, and the collecting wire harness 130 is fixed by the first limiting piece 114, so that stable connection between the collecting wire harness 130 and the connecting component 120 can be ensured, and further collection failure caused by excessive concentration of stress at the connecting position of the collecting wire harness 130 and the connecting component 120 is avoided.

In the embodiment of the utility model, the wire harness bracket 110 is used for the battery module 10, the wire harness bracket 110 is provided with a mounting surface 111, the mounting surface 111 is used for mounting a connecting assembly 120 electrically connected with a battery cell 200 in the battery module 10, a first avoiding hole 112 is formed in the mounting surface 111, the first avoiding hole 112 is used for avoiding an electrode of the battery cell 200 in the battery module 10, a first limiting piece 114 is convexly arranged on the mounting surface 111 at a position close to the first avoiding hole 112, the first limiting piece 114 has elasticity, a first limiting space 1142 is formed on the first limiting piece 114, and the first limiting space 1142 is used for mounting the acquisition wire harness 130. According to the utility model, the first limiting piece 114 is arranged on the mounting surface 111 of the wire harness bracket 110 at a position close to the first avoiding hole 112, and the first limiting piece 114 has elasticity, so that when the acquisition wire harness 130 in the first limiting space 1142 on the first limiting piece 114 is connected with the connecting component 120, the first limiting piece 114 can limit the freedom degree of the acquisition wire harness 130 by utilizing plastic deformation of the first limiting piece, so that the acquisition failure caused by the excessive concentration of stress at the connection part of the acquisition wire harness 130 and the connecting component 120 is prevented.

Optionally, as shown in fig. 2, a wire harness hole 1141 is formed in the first limiting member 114, the wire harness hole 1141 is set as a first limiting space 1142, the collecting wire harness 130 is threaded through the wire harness hole 1141, and a side wall of the wire harness hole 1141 is used for abutting against an outer peripheral surface of the collecting wire harness 130. That is, the first limiting member 114 is formed with a through hole, when the collection wire harness 130 is fixed on the mounting surface 111, the collection wire harness 130 can directly pass through the wire harness hole 1141 on the first limiting member 114, and the side wall of the wire harness hole 1141 is abutted with the outer peripheral surface of the collection wire harness 130, so that the surface fixation of the collection wire harness 130 by the first limiting member 114 is realized, and the stability of the collection wire harness 130 in the first limiting member 114 is further improved.

In some embodiments, the side surface of the first limiting member 114 is provided with a first mounting opening 1143, the extending direction of the first mounting opening 1143 is consistent with the extending direction of the wire harness hole 1141 and penetrates through the first limiting member 114, and the first mounting opening 1143 is communicated with the wire harness hole 1141, so that the collection wire harness 130 can enter the wire harness hole 1141 through the first mounting opening 1143, and when the collection wire harness 130 is mounted in the first limiting member 114, the collection wire harness 130 can be clamped into the first limiting space 1142 through the first mounting opening 1143 on the side surface of the first limiting member 114, and further fixation of the collection wire harness 130 is achieved, so that collection failure caused by too concentrated stress at the connection part of the collection wire harness 130 and the connection assembly 120 is avoided, and meanwhile, the mounting of the collection wire harness 130 is facilitated.

The orthographic projection of the first mounting opening 1143 on the first limiting member 114 is located in the wire harness hole 1141, that is, the caliber of the first mounting opening 1143 is smaller than the aperture of the wire harness hole 1141, and the aperture of the wire harness hole 1141 is smaller than or equal to the diameter of the acquisition wire harness 130, that is, when the acquisition wire harness 130 is mounted, the first mounting opening 1143 needs to be firstly opened by extrusion, then passes through the first mounting opening 1143 and enters the wire harness hole 1141, and then the acquisition wire harness 130 is clamped in the first limiting space 1142 under the action force of plastic deformation of the first limiting member 114, so that the degree of freedom of the acquisition wire harness 130 is limited.

In some embodiments, the first mounting opening 1143 is located at a side of the first limiting member 114 facing away from the mounting surface 111, that is, when the collection wire harness 130 is mounted in the first limiting member 114, the collection wire harness 130 can be clamped into the first limiting space 1142 from top to bottom, and when the collection wire harness 130 is connected with the connection assembly 120, the collection wire harness 130 needs to be bent to the left or right in the plane of the mounting surface 111 so as to be welded with the corresponding connection assembly 120, at this time, a reaction force opposite to the bending direction exists on the collection wire harness 130, and by disposing the first mounting opening 1143 at a side of the first limiting member 114 facing away from the mounting surface 111, the collection wire harness 130 can be effectively prevented from being separated from the first limiting member 114 due to the reaction force generated by bending, so as to ensure the connection stability of the collection wire harness 130 and the connection assembly 120.

In other embodiments, the setting position of the first mounting opening 1143 can also be adjusted according to the bending direction of the collection harness 130. For example, when the collection wire harness 130 is bent leftwards and electrically connected with the connection assembly 120, a rebound force to the right is formed on the collection wire harness 130, and at this time, the first mounting opening 1143 can be disposed on the first limiting member 114 corresponding to the left side of the collection wire harness 130, so as to avoid the collection wire harness 130 from being ejected from the first mounting opening 1143; similarly, when the collection wire harness 130 is bent rightward to be electrically connected with the connection assembly 120, a leftward rebound force is formed on the collection wire harness 130, and at this time, the first mounting opening 1143 can be disposed on the first limiting member 114 corresponding to the right side of the collection wire harness 130, so as to avoid the collection wire harness 130 from being popped out from the first mounting opening 1143.

It should be noted that, in the embodiment of the present utility model, the left side and the right side are determined according to the bending direction of the bent end of the collecting wire harness 130 relative to the other end, and when the bent end is changed when the collecting wire harness 130 is installed, the corresponding left side and right side are also changed, which is not limited in particular.

Optionally, a plurality of first limiting members 114 are disposed on the mounting surface 111 near the first avoidance hole 112 in parallel, and a distribution direction of the plurality of first limiting members 114 is consistent with an extension direction of a bending section of the collection wire harness 130, so that the collection wire harness 130 passes through first limiting spaces 1142 of the plurality of first limiting members 114 at the same time and is electrically connected with the connection assembly 120, thereby further improving the mounting stability of the collection wire harness 130, and reducing the risk of collection failure caused by too concentrated stress at a connection position of the collection wire harness 130 and the connection assembly 120.

In some embodiments, the mounting surface 111 is provided with a plurality of first avoidance holes 112, and at least one first limiting member 114 is correspondingly disposed at a position on the mounting surface 111 near each first avoidance hole 112, so that the degree of freedom of the acquisition harness 130 can be limited by the corresponding first limiting member 114 when the acquisition harness 130 is electrically connected with the corresponding connection assembly 120, and thus the risk of acquisition failure caused by too concentrated stress at the connection position of the acquisition harness 130 and the connection assembly 120 is reduced, and further the stability of signal acquisition of the acquisition harness 130 is ensured.

It should be noted that, in addition to defining the degree of freedom of the collection wire harness 130 by adopting the manner of opening the wire harness hole 1141, the first limiting member 114 may also be directly formed by two elastic members, and the collection wire harness 130 may be clamped and fixed by opening and closing the two elastic members. The specific structure of the first limiting member 114 can be designed and adjusted according to actual use requirements, and only the first limiting member 114 needs to ensure that the degree of freedom of the collecting wire harness 130 can be limited by utilizing plastic deformation of the first limiting member 114, so as to avoid collecting failure caused by too concentrated stress at the joint of the collecting wire harness 130 and the connecting assembly 120, and the specific limitation is not required.

When the first limiting member 114 is designed, the sizes of the wire harness holes 1141 and the first mounting holes 1143 can be determined according to the diameter range and the mounting number of the collection wire harnesses 130, so as to meet different mounting requirements of the collection wire harnesses 130, and improve the applicability of the wire harness bracket 110.

In some embodiments, the diameter of the collection harness 130 in the present utility model can be set to be greater than or equal to 1.2mm and less than or equal to 1.4mm. Specifically, in the actual manufacturing process, the diameter of the collection wire harness 130 can be set to be 1.2mm, 1.3mm or 1.4mm, and the specific diameter value thereof can be designed and adjusted according to the actual use requirement, and the present utility model is not limited in particular.

Optionally, as shown in fig. 5 and fig. 6, a second avoidance hole 113 is formed on the mounting surface 111, the second avoidance hole 113 is used for avoiding an explosion-proof valve of the battery core 200 in the battery module 10, a second limiting member 115 is convexly arranged on the mounting surface 111 near the second avoidance hole 113, a second limiting space 1153 is formed on the second limiting member 115, and the second limiting space 1153 is used for installing the acquisition wire harness 130, so that the acquisition wire harness 130 sequentially passes through the second limiting space 1153 and the first limiting space 1142 to be electrically connected with the connecting assembly 120.

That is, when the collection harness 130 is mounted to the harness bracket 110, the collection harness 130 sequentially passes through the second limiting space 1153 and the first limiting space 1142, so as to further limit the degrees of freedom of the collection harness 130. Meanwhile, the second limiting piece 115 is arranged on the mounting surface 111 at a position close to the second avoidance hole 113, so that the acquisition wire harness 130 is also close to the second avoidance hole 113 after being mounted, namely, the acquisition wire harness 130 is close to the explosion-proof valve of the battery cell 200 in the battery module 10, and therefore when the battery module 10 is in thermal runaway, the acquisition wire harness 130 can rapidly monitor the abnormality of the battery module 10 through high-temperature gas sprayed by the explosion-proof valve of the battery cell 200; if the open flame sprayed out of the explosion-proof valve of the battery cell 200 directly burns out the acquisition wire harness 130, the acquisition wire harness 130 can also rapidly reflect the abnormality of the battery module 10 through the abnormality of the monitoring data, so that the timeliness of monitoring of abnormal signals is ensured.

The second limiting member 115 includes a first limiting portion 1151 and a second limiting portion 1152, the first limiting portion 1151 and the second limiting portion 1152 are respectively disposed on the mounting surface 111, and the first limiting portion 1151, the second limiting portion 1152 and the mounting surface 111 enclose to form a second limiting space 1153. That is, when the collection wire harness 130 is installed, the collection wire harness 130 is directly installed on the installation surface 111 of the wire harness bracket 110, and the limitation of the installation position is realized through the mutual cooperation of the first limiting part 1151 and the second limiting part 1152, so that the structural design is helpful to reduce the whole space occupation of the second limiting part 115 and the collection wire harness 130.

That is, one end of the first limiting portion 1151 and one end of the second limiting portion 1152 are connected to the mounting surface 111, and the other end of the first limiting portion 1151 and the second limiting portion 1152 are spaced apart to form a second mounting opening 1154, that is, the first limiting portion 1151 and the second limiting portion 1152 are respectively in an inverted L shape. When the collection wire harness 130 is installed in the second limiting piece 115, the second installation opening 1154 can be clamped into the second limiting space 1153, and further limitation of the degree of freedom of the collection wire harness 130 is achieved.

The second limiting member 115 has elasticity, that is, when the collection wire harness 130 is installed in the second limiting space 1153 of the second limiting member 115, the second limiting member 115 can limit the degree of freedom of the collection wire harness 130 by using plastic deformation of itself, which can improve the installation stability of the collection wire harness 130 and the applicability of the second limiting member 115 to collection wire harnesses 130 with different sizes.

Optionally, an opening 1155 is formed on the mounting surface 111 at a position corresponding to the second mounting opening 1154, the opening 1155 penetrates through the wire harness bracket 110 along the thickness direction of the wire harness bracket 110, that is, when the collecting wire harness 130 is mounted in the second limiting space 1153, the collecting wire harness 130 only presses the second limiting member 115 with respect to the position corresponding to the second limiting member 115, and the opening on the mounting surface 111 partially releases the partial pressure, so as to avoid the damage and failure of the collecting wire harness 130 due to the excessive stress at the position corresponding to the second limiting space 1153, and further ensure that the collecting wire harness 130 mounted in the second limiting space 1153 effectively monitors the signal of the battery module 10.

The orthographic projection of the second mounting opening 1154 on the mounting surface 111 is located in the opening 1155, that is, in the thickness direction of the wire harness bracket 110, the second mounting opening 1154 is located in the area where the opening 1155 is located, and after the acquisition wire harness 130 enters the second limiting space 1153 through the second mounting opening 1154, damage and failure of the acquisition wire harness 130 in the corresponding second limiting space 1153 due to overlarge stress can be avoided to the greatest extent, so that effective monitoring of the signal of the battery module 10 by the acquisition wire harness 130 which is safely installed in the second limiting space 1153 is further ensured.

In some embodiments, the first limiting member 114 and the wire harness support 110 are integrally formed, that is, the first limiting member 114 is a part of the wire harness support 110, and can be integrally formed in an injection molding manner, so as to improve the fixing effect of the wire harness support 110 on the acquisition wire harness 130, and avoid that the acquisition wire harness 130 and the connection component 120 are separated from each other due to welding caused by pulling of an external force of the acquisition wire harness 130, so that acquisition failure is caused.
