[0035] like Figure 1-4 As shown, a battery pack bottom supporting vibration tool of the utility model comprises a perforated plate 1, a plurality of mounting brackets 2 and a bottom supporting tool 3, which is used to fix a battery pack 4 so as to perform a vibration test on the battery pack 4.

[0036] The orifice plate 1 is the main structure of the vibration tooling and is used to carry other components.

[0037] The mounting bracket 2 is used to clamp and fix the battery pack 4. The mounting bracket 2 is fixedly arranged on the orifice plate 1, and a plurality of mounting brackets 2 are abutted against at least two opposite sides of the battery pack 4. Figure 2 As shown, it is preferred that the mounting bracket 2 supports two side surfaces of the battery pack 4 that are parallel to its length direction, so as to improve the fixing stability of the battery pack 4 .

[0038] The bottom supporting fixture 3 is used for bottom supporting the battery pack 4. The bottom supporting fixture 3 is fixedly arranged on the orifice plate 1 and abuts against the bottom side of the battery pack 4, wherein the bottom side of the battery pack 4 is the opposite side of the opening side of the battery pack 4; when the surface of the orifice plate 1 for mounting the battery pack 4 and the bottom side of the battery pack 4 are not on the same plane, the bottom supporting fixture 3 can be used to support the battery pack 4 to limit the longitudinal installation position of the battery pack 4, and cooperate with the mounting bracket 2 to limit the transverse installation position of the battery pack 4, so as to avoid installation errors between the battery pack 4 and its installation position on the vibration fixture, thereby improving the installation accuracy of the battery pack 4 on the vibration fixture; the relative position of the bottom supporting fixture 3 and the orifice plate 1 is adjustable, and this relative position adjustment includes the adjustable relative spacing between the two and the adjustable relative angle between the two, so that the vibration fixture can adapt to battery packs 4 with different installation requirements.

[0039] The bottom supporting tooling 3 includes a supporting plate 31 and a plurality of height-adjusting frames 32, wherein the supporting plate 31 is set against the bottom side of the battery pack 4; the height-adjusting frames 32 are used to adjust the distance between the supporting plate 31 and the orifice plate 1, and the height-adjusting frames 32 are fixedly set on the orifice plate 1 and are against the end of the supporting plate 31 away from the battery pack 4; the supporting plate 31 and the height-adjusting frames 32 are connected by abutment rather than fixedly, and their adjustable performance is better.

[0040] like Figure 3 As shown, the height adjustment frame 32 includes a fixing portion 321 and a contact portion 322, wherein the fixing portion 321 is fixedly arranged on the orifice plate 1; the contact portion 322 is fixedly arranged on a side of the fixing portion 321 away from the orifice plate 1, and the side of the contact portion 322 away from the fixing portion 321 contacts the end of the supporting plate 31 away from the battery pack 4, and the distance between the contact portion 322 close to the supporting plate 31 and the orifice plate 1 gradually increases from the end close to the supporting plate 31 to the end away from the supporting plate 31, that is, The side of the abutment portion 322 close to the supporting plate 31 is in the shape of a wedge-shaped slope. By moving the fixing portion 321, the different positions of the wedge-shaped slope of the abutment portion 322 can be made to abut against the supporting plate 31 to adjust the height of the end of the supporting plate 31 relative to the orifice plate 1; when the multiple ends of the supporting plate 31 are synchronously raised, the relative distance between the bottom support fixture 3 and the orifice plate 1 can be adjusted, and when the multiple ends are asynchronously raised, the relative angle between the bottom support fixture 3 and the orifice plate 1 can be adjusted.

[0041] like Figure 3 As shown, the end of the supporting plate 31 away from the battery pack 4 is provided with a connecting surface 301 that abuts against the abutting portion 322, and the connecting surface 301 is parallel to the abutting portion 322, thereby increasing the contact area between the supporting plate 31 and the abutting portion 322, making the two have a good assembly relationship, and making the adjustment operation of the two more stable.

[0042] The supporting plate 31 includes a central plate 311 and a plurality of adjusting rods 312, wherein the central plate 311 is arranged against the bottom side of the battery pack 4 and is the main supporting member of the battery pack 4; the adjusting rods 312 are fixedly arranged on the central plate 311, and are mainly used to cooperate with the height-adjusting frame 32 to realize the height adjustment operation of the supporting plate 31, and the height-adjusting frame 32 is against one end of the adjusting rod 312 away from the battery pack 4 and away from the central plate 311; of course, it is preferred that the side of the adjusting rod 312 away from the height-adjusting frame 32 is also against the battery pack 4 to increase the contact area between the supporting plate 31 and the battery pack 4 and improve its abutment stability.

[0043] Specifically, four adjusting rods 312 and four height-adjusting racks 32 are provided. Preferably, the four adjusting rods 312 and the four height-adjusting racks 32 are arranged in a circular array around the center line of the battery pack 4 to adjust the heights of the four top corners of the bottom support tooling 3 respectively. By adjusting several or all of the height-adjusting racks 32, not only the relative distance between the support plate 31 and the orifice plate 1 can be adjusted, but also the relative angle between the support plate 31 and the orifice plate 1 can be adjusted, so that the vibration tooling can adapt to battery packs 4 with different installation position requirements.

[0044] like Figure 1 As shown, a plurality of mounting holes 101 are provided on the orifice plate 1, and the fixing portion 321 and the mounting bracket 2 are selectively fixedly connected to one or several of the mounting holes 101, so that the positions of the fixing portion 321 and the mounting bracket 2 can be adjusted to make the vibration tooling adaptable to battery packs 4 of different specifications.

[0045] like Figure 1 As shown, a connecting hole 302 is opened on the fixing portion 321. The connecting hole 302 is an oblong hole and is fixedly connected to one of the mounting holes 101. The two are preferably fixed with bolts. The sliding of the connecting hole 302 and the bolts can be utilized to facilitate the adjustment of the fixing portion 321, thereby quickly adjusting the end height of the supporting plate 31.

Specifically, bolt holes are provided on the connecting frame 42 and the mounting bracket 2, and the two can be fixedly connected by bolts, thereby improving the fixing firmness and anti-deflection performance of the battery pack 4 and the vibration tooling.

[0047] The use method of the battery pack bottom supporting vibration tooling of the utility model is as follows:

[0048] First, the relative distance and relative angle between the support plate 31 and the orifice plate 1 are adjusted by moving the fixing portion 321 so that the vibration tooling meets the installation position requirements of the battery pack 4. Then, the battery pack 4 is placed on the support plate 31. Finally, the side of the battery pack 4 is supported and fixed using the mounting bracket 2, and the mounting bracket 2 is fixedly connected to the connecting frame 42. Of course, the battery pack 4 can also be placed on the support plate 31 first, and then the relative distance and relative angle between it and the orifice plate 1 are adjusted.
