[0002] With the rapid development of new energy vehicles, battery packs, as the heart of new energy vehicles, have attracted much attention. Currently, when new energy vehicles are driving on the road, vibration is inevitable. As we all know, vibration can easily cause structural deformation. For battery packs, once structural deformation occurs, there will be safety hazards. Therefore, before the battery pack leaves the factory, different vibration tests need to be performed on the battery pack according to the vehicle model.

DETAILED DESCRIPTION

[0037] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Reference Figures 1-8 As shown, the embodiment of the present invention provides a battery pack vibration tool with adjustable gap. The battery pack 100 is provided with a first mounting portion 110 and a second mounting portion 120 on both sides along the width direction, and two third mounting portions 130 and two fourth mounting portions 140 on both sides along the length direction. The tool comprises a vibration table 1, four first connecting frames 2, and two second connecting frames 3, wherein:

[0039] The vibration table 1 is provided with mounting holes 11 distributed at equal intervals in the horizontal and vertical directions for mounting the first connecting frame 2 and the second connecting frame 3, so that the battery pack 100 vibration tooling can be applied to battery packs 100 of different sizes, thereby improving applicability;

[0040] Four first connecting frames 2 are detachably mounted on the vibration table 1. The first connecting frames 2 are provided with first mounting portions 221 that are adjustable in height and angle. Two of the first connecting frames 2 are located on one side of the battery pack 100 along the length direction, and the first mounting portions 221 of the two first connecting frames 2 are respectively connected to the two third mounting portions 130. The other two first connecting frames 2 are located on the other side of the battery pack 100 along the length direction, and the first mounting portions 221 of the other two first connecting frames 2 are respectively connected to the two fourth mounting portions 140. The connection here can be a bolt connection.

[0041] The two second connecting frames 3 can be detachably mounted on the vibration table 1 , and a second mounting portion 321 is provided on the second connecting frame 3 . The second mounting portions 321 of the two second connecting frames 3 are respectively used to connect with the first mounting portion 110 and the second mounting portion 120 , and the connection here can be a bolt connection.

[0042] The gap-adjustable battery pack vibration tooling proposed in this embodiment is capable of adjusting the height and angle of each first mounting portion 221, thereby eliminating the height gap and angular gap between the first mounting portion 221 and the third mounting portion 130 or the fourth mounting portion 140. By adjusting the angles of the four first connecting frames 2, the angles of the first mounting portion 110 and the second mounting portion 120 of the battery pack 100 can also be adjusted, thereby eliminating the height gap and angular gap between the second mounting portion 321 of the second connecting frame 3 and the first mounting portion 110 or the second mounting portion 120, thereby improving the accuracy of the vibration test.

[0043] In some embodiments, the first connecting frame 2 includes a first base 21, a first mounting plate 22, and four height adjustment mechanisms 23. The first base 21 is detachably connected to the vibration table 1 and the first mounting plate 22, respectively. The first mounting portion 221 is located on the first mounting plate 22. The height adjustment mechanisms 23 are mounted on the first base 21 and connected to the first mounting plate 22. The four height adjustment mechanisms 23 are arranged along the length and width of the first mounting plate 22, and their connection points with the first mounting plate 22 can be connected to form a rectangle. During the height adjustment process of the four height adjustment mechanisms 23, the angle of the first mounting portion 221 can be synchronously adjusted by controlling the height adjustment amount of the height adjustment mechanisms 23, thereby eliminating angular and height gaps.

[0044] In some embodiments, the height adjustment mechanism 23 includes an adjustment plate 231 and two connecting bolts 232. The adjustment plate 231 is provided with two parallel waist-shaped holes 2311 in a direction perpendicular to the vibration table 1. The first base 21 is provided with two connecting screw holes 211 corresponding to each height adjustment mechanism 23. The connecting bolts 232 pass through the waist-shaped holes 2311 and are connected to the connecting screw holes 211. Before adjustment, the connecting bolts 232 are loosened, and the waist-shaped holes 2311 can slide along the connecting bolts 232, thereby moving the adjustment plate 231 in the vertical direction. After the height is adjusted, the connecting bolts 232 are rotated to connect and fix the adjustment plate 231 to the first base 21, thereby achieving height adjustment.

[0045] In some embodiments, the battery pack 100 vibration tooling also includes four angle fine-tuning mechanisms 24, which are respectively connected to the adjustment plate 231 and the first mounting plate 22, and the angle fine-tuning mechanism 24 includes a support member 241, a connecting shaft 242 and a fixing bolt 243. The top surface of the support member 241 is connected to the first mounting plate 22, and the connecting shaft 242 is fixedly connected to the end surface of the support member 241. The adjustment plate 231 is provided with a rotating hole 2312 and a fixing screw hole 2313 that are perpendicular to each other and connected. The connecting shaft 242 is rotatably installed in the rotating hole 2312, and the fixing bolt 243 is threadedly connected to the fixing screw hole 2313 for abutting the connecting shaft 242. When the support member 241 rotates around the rotation hole 2312 until the first mounting portion 221 is in contact with the third mounting portion 130 or the fourth mounting portion 140 of the battery pack 100, the fixing bolt 243 is screwed in. The fixing bolt 243 abuts against the connecting shaft 242 to limit the rotation of the connecting shaft 242, thereby fine-tuning the angle of the first mounting plate 22 and further improving the accuracy of the angle adjustment.

[0046] In some embodiments, a limiting surface 2421 is provided on the outer wall of the connecting shaft 242 at the position where it abuts the fixing bolt 243. By providing the limiting surface 2421 on the outer wall of the connecting shaft 242 at the position where it abuts the fixing bolt 243, the fixing bolt 243 abuts against the limiting surface 2421, which effectively prevents the connecting shaft 242 from rotating and improves the reliability of the device. In actual design, multiple limiting surfaces 2421 can be provided, for example, four limiting surfaces 2421 can be provided to form a square structure, so that when the connecting shaft 242 rotates to different positions, the fixing bolt 243 can abut against the corresponding limiting surface 2421.

[0047] In some embodiments, the first mounting plate 22 is disposed protruding from the first base 21, and the first mounting portion 221 is located at the portion of the first mounting plate 22 that protrudes from the first base 21. Since the first mounting portion 221 is located at the portion of the first mounting plate 22 that protrudes from the first base 21, it is easy to observe the height gap and angular gap between the first mounting portion 221 and the third mounting portion 130 or the fourth mounting portion 140, so that corresponding adjustments can be made to eliminate the height gap and angular gap, thereby improving operational convenience.

[0048] In some embodiments, the second connecting frame 3 includes a second base 31 and a second mounting plate 32. The second base 31 is detachably connected to the vibration table 1 and the second mounting plate 32, respectively. The second mounting portion 321 is located on the second mounting plate 32. The detachable connection between the second base 31 and the vibration table 1 and the second mounting plate 32, and the separate design of the second base 31 and the second mounting plate 32 facilitate subsequent placement of the battery pack 100 under the second mounting plate 32 before connecting the second mounting plate 32 to the second base 31, thereby improving reliability.

[0049] In some embodiments, the second mounting plate 32 is disposed protruding from the second base 31, and the second mounting portion 321 is located at the portion of the second mounting plate 32 that protrudes from the second base 31. Since the second mounting portion 321 is located at the portion of the second mounting plate 32 that protrudes from the second base 31, it is easy to observe the height gap and angular gap between the second mounting portion 321 and the first mounting portion 110 or the second mounting portion 120, so that corresponding adjustments can be made to eliminate the height gap and angular gap, thereby improving operational convenience.

[0050] In some embodiments, the second base 31 is hollowed out, and a reinforcing plate 33 is provided on the second base 31 in a direction perpendicular to the vibration table 1. The hollowed-out design of the second base 31 makes the structure more lightweight. While achieving lightweight, the reinforcing plate 33 provided on the second base 31 in a direction perpendicular to the vibration table 1 increases the vertical strength of the second base 31, thereby improving the second base 31's ability to resist vibration and shock, and extending the service life of the device.

[0051] In some embodiments, the first mounting portion 221 is located above the third mounting portion 130 and the fourth mounting portion 140, and the second mounting portion 321 is located above the first mounting portion 110 and the second mounting portion 120. With the above design, the battery pack 100 can be placed within the frame formed by the first connecting frame 2 and the second connecting frame 3, and then the first mounting plate 22 and the second mounting plate 32 are installed. The battery pack 100 can then be hoisted at a fixed height to prevent the weight of the battery pack 100 from pressing on the surface of the first mounting portion 221 and affecting the adjustment of the first mounting portion 221, thereby improving the reliability and accuracy of the adjustment.

[0052] The working principle of the gap-adjustable vibration tooling for the battery pack 100 is as follows: the height of each first mounting part 221 is adjusted by four height adjustment mechanisms 23, and the angle of the first mounting part 221 is synchronously adjusted by controlling the height adjustment amount of the height adjustment mechanism 23, thereby eliminating the angular gap and the height gap, thereby eliminating the height gap and the angular gap between the first mounting part 221 and the third mounting part 130 or the fourth mounting part 140. By adjusting the angles of the four first connecting frames 2, the angles of the first mounting part 110 and the second mounting part 120 of the battery pack 100 can also be adjusted, thereby eliminating the height gap and the angular gap between the second mounting part 321 of the second connecting frame 3 and the first mounting part 110 or the second mounting part 120, thereby improving the accuracy of the vibration test.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
