Description

Technical Field

[0001] This application relates to the field of battery assembly technology, specifically to a fixing fixture. Background Technology

[0002] In the field of battery assembly technology, the battery disconnect unit (BDU) and copper busbars are typically assembled manually. Specifically, the worker holds the copper busbar and tightens it to the corresponding terminal of the BDU using bolts. However, because the copper busbar rotates due to the torque force of the bolts during tightening, the final angle of the copper busbar cannot be kept consistent, causing the copper busbar protective cover to be unable to be installed in subsequent processes due to spatial interference. Utility Model Content

[0003] In view of the above, it is necessary to provide a fixing fixture to improve the accuracy of fixing.

[0004] This application provides a fixing fixture for fixing a copper busbar to a battery cell. The copper busbar includes a main body, a connecting body, and a bent body with its two ends respectively connected to the main body and the connecting body. One end of the battery cell is provided with a mounting hole. The fixing fixture includes:

[0007] A bearing seat is disposed on the base and spaced apart from the support seat, and the bearing seat is used to support the main body;

[0008] A limiting seat is provided on the base and located between the support seat and the bearing seat. The limiting seat has a limiting groove that extends through the limiting seat in the direction from the bearing seat to the support seat. The limiting groove is used to hold the bent body to guide the connector into the mounting hole.

[0009] In the aforementioned fixture, after the copper busbar connector is inserted into the mounting hole, the limiting groove of the limiting seat can hold the bent part of the copper busbar to limit its position. This prevents the copper busbar from rotating when fixing the connector and the battery unit, thereby improving the accuracy of fixing the copper busbar and the battery unit.

[0010] In some embodiments, the surface of the support seat opposite to the base is provided with a support groove, which extends through the support seat in the direction from the support seat to the base, and is used to hold the main body.

[0011] In some embodiments, the bearing groove and the limiting groove are correspondingly arranged along the extending direction of the bearing groove.

[0012] In some embodiments, the support seat and the base are slidably connected along the extension direction of the support groove.

[0013] In some embodiments, the support seat and the base are slidably connected in a direction perpendicular to the extension direction of the support groove.

[0014] In some embodiments, the limiting seat and the base are slidably connected along the extending direction of the limiting groove.

[0015] In some embodiments, the limiting seat and the base are slidably connected in a direction perpendicular to the extension direction of the limiting groove.

[0016] In some embodiments, the support base has a support groove on its surface opposite to the base, the support groove being used to accommodate part of the battery cell.

[0017] In some embodiments, the fixing fixture further includes:

[0018] A stop is provided on the base and located on the side of the support to stop the battery cell.

[0019] In some embodiments, at least one of the support seat and the limiting seat is rotatably connected to the base. Attached Figure Description

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows communication between the two; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two elements or the interaction between two elements. In the description of this application, it should be noted that "multiple" means two or more, unless otherwise expressly and specifically limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0025] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the copper busbar and battery unit applicable to the embodiments of this application. Specifically, the copper busbar 200 includes a main body 210, a connector 220, and a bent body 230 with both ends connected to the main body 210 and the connector 220 respectively. One end of the battery unit 300 is provided with a mounting hole 300a. The connector 220 is used to insert into the mounting hole 300a and is fixedly connected to the battery unit 300 by bolts.

[0027] Please see Figure 2 This application provides a fixing fixture 100 for fixing a copper busbar 200 to a battery unit 300 to prevent the copper busbar 200 from rotating when it is fixed to the battery unit 300, thereby improving the accuracy of fixing the copper busbar 200 to the battery unit 300.

[0028] For ease of description, in Figure 2 A three-dimensional coordinate system has been added. The X-axis, Y-axis, and Z-axis are all perpendicular to each other.

[0029] Please see Figure 1 and Figure 2 In some embodiments, the fixing fixture 100 includes a base 110, a support 120, a carrier 130, and a limiting seat 140. The base 110 is generally hollow. The support 120 is disposed on the base 110 and is used to support the battery unit 300. The carrier 130 is disposed on the base 110 and spaced apart from the support 120 along the X-axis. The carrier 130 is used to support the main body 210. The limiting seat 140 is disposed on the base 110 and located between the support 120 and the carrier 130. The limiting seat 140 has a limiting groove 140a that extends through the limiting seat 140 along the X-axis. The limiting groove 140a is used to hold the bent body 230 and guide the connector 220 to be inserted into the mounting hole 300a.

[0030] In the aforementioned fixing fixture 100, after the connecting body 220 of the copper busbar 200 is inserted into the mounting hole 300a, the limiting groove 140a of the limiting seat 140 can hold the bent body 230 of the copper busbar 200 to limit the copper busbar 200. This can prevent the copper busbar 200 from rotating when fixing the connecting body 220 and the battery unit 300, thereby improving the accuracy of fixing the copper busbar 200 and the battery unit 300.

[0031] Please see Figure 2 In some embodiments, the surface of the support seat 130 opposite to the base 110 is provided with a support groove 130a, which penetrates the support seat 130 along the X-axis and is used to hold the main body 210.

[0032] Therefore, the bearing groove 130a can limit the main body 210, which helps to improve the accuracy of fixing the copper busbar 200.

[0033] In some embodiments, the bearing groove 130a and the limiting groove 140a are respectively provided along the X-axis direction.

[0034] Therefore, the above settings can drive the main body 210 to move along the X-axis, thereby improving the placement accuracy of the copper busbar 200.

[0035] In some embodiments, the support 130 and the base 110 are slidably connected along the X-axis direction.

[0036] Therefore, through the above settings, the distance between the bearing seat 130 and the base 110 along the X-axis can be adjusted to accommodate copper busbars 200 of different lengths.

[0037] In some embodiments, the support 130 and the base 110 are slidably connected along the Z-axis direction.

[0038] Therefore, through the above settings, the relative arrangement of the bearing seat 130 and the base 110 along the Z-axis direction can be adjusted so that the bearing seat 130 can be adapted to copper busbars 200 with different bending degrees.

[0039] In some embodiments, the limiting seat 140 and the base 110 are slidably connected along the X-axis direction.

[0040] Therefore, through the above settings, the distance between the limit seat 140 and the base 110 along the X-axis can be adjusted to accommodate copper busbars 200 of different lengths.

[0041] In some embodiments, the limiting seat 140 and the base 110 are slidably connected along the Z-axis direction.

[0042] Therefore, through the above settings, the relative position of the limiting seat 140 and the base 110 along the Z-axis can be adjusted so that the limiting seat 140 can be adapted to copper busbars 200 with different bending degrees.

[0043] In some embodiments, the limiting seat 140 and the base 110 are slidably connected along the Y-axis direction.

[0044] Therefore, with the above settings, the main body 210 of the copper busbar 200 can be placed on the support seat 130 during operation, and the connecting body 220 of the copper busbar 200 can be inserted into the mounting hole 300a. Then, the limiting seat 140 is moved along the Y-axis to hold the bent body 230 of the copper busbar 200 into the limiting groove 140a, which can reduce the difficulty of placing the copper busbar 200.

[0045] Please see Figure 2 In some embodiments, the support base 120 has a support groove 120a on the surface opposite to the base 110, and the support groove 120a is used to accommodate part of the battery unit 300.

[0046] Therefore, the support groove 120a can limit the battery cell 300, which helps to improve the accuracy of the positioning of the copper busbar 200 and the battery cell 300.

[0047] Please see Figure 2 In some embodiments, the fixture 100 further includes a stop 150. The stop 150 is disposed on the base 110 and surrounding the support 120 to stop the battery unit 300.

[0048] Therefore, the stop 150 can limit the battery unit 300, preventing the battery unit 300 from moving relative to the support 120, which helps to improve the stability of the battery unit 300.

[0049] For example, a stop 150 is provided on the side of the support 120 along the Y-axis direction to define the battery cell 300 in the Y-axis direction.

[0050] In some embodiments, at least one of the support seat 130 and the limiting seat 140 is rotatably connected to the base 110.

[0051] Therefore, by means of the above settings, the relative angle between at least one of the bearing seat 130 and the limiting seat 140 and the base 110 can be adjusted, which is beneficial to improving the limiting accuracy of the copper busbar 200.

[0052] For example, the support seat 130 is rotatably connected to the base 110, and the rotation axis of the support seat 130 is parallel to the Z-axis direction; or, the limiting seat 140 is rotatably connected to the base 110, and the rotation axis of the limiting seat 140 is parallel to the Z-axis direction; or, the support seat 130 is rotatably connected to the base 110, and the rotation axis of the support seat 130 is parallel to the Z-axis direction, and the limiting seat 140 is rotatably connected to the base 110, and the rotation axis of the limiting seat 140 is parallel to the Z-axis direction.

Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
