[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0026] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0027] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0028] like Figure 1 and Figure 2 As shown, the vibration test fixture according to the embodiment of the present application includes a base plate and a first clamping assembly 20 and a second clamping assembly 30 arranged on the base plate. The limiting direction of the first clamping assembly 20 is along the horizontal direction, and the limiting direction of the second clamping assembly 30 is along the vertical direction. The first clamping assembly 20 includes two first clamping parts 21 arranged opposite to each other, and the distance between the two first clamping parts 21 is adjustable.

[0029] Specifically, since the limiting direction of the first clamping assembly 20 is along the horizontal direction, when the vibration test equipment needs to test the vibration of the battery pack in the first direction or the second direction, wherein one of the first direction and the second direction is along the X-axis direction and the other is along the Y-axis direction, the two ends of the battery pack in the first direction can be placed between the two first clamping parts 21, and the distance between the two first clamping parts 21 is adjusted so that the two first clamping parts 21 clamp the battery pack, and the second clamping assembly 30 is used to limit the battery pack in the vertical direction, thereby achieving the first direction of the battery pack. Perform a vibration test in the second direction, then loosen the two first clamping parts 21, loosen the second clamping assembly 30, take out the battery pack and adjust the position, place the two ends of the battery pack in the second direction between the two first clamping parts 21, adjust the distance between the two first clamping parts 21 so that the two first clamping parts 21 clamp the battery pack, and use the second clamping assembly 30 to limit the battery pack in the vertical direction, thereby realizing a vibration test on the second direction of the battery pack. When performing a vibration test in the vertical direction, the test can be performed directly without adjusting the position of the battery pack.

[0030] It can be understood that the distance between the two first clamping parts 21 is adjustable, which means that the position of at least one first clamping part 21 on the base plate can be adjusted relative to the base plate. The first clamping part 21 is connected to the base plate by using a gear rack, or by using a screw nut, or by using a sliding groove in combination with a fastener 322 to achieve fixation after adjustment, and this application does not impose any restrictions.

[0031] According to the vibration test fixture of the embodiment of the present application, the first clamping assembly 20 can be used to limit the battery pack in two horizontal directions to perform a vibration test. While simplifying the structural setting, the distance between the two first clamping parts 21 can be adjusted to better adapt to battery packs of different specifications, ensuring that the battery pack can fit when fixed to avoid gaps between the battery packs.

[0032] like Figure 1 and Figure 2 As shown, according to the vibration test fixture of the embodiment of the present application, the second clamping assembly 30 includes a second clamping portion 31 opposite to the bottom plate, and the distance between the second clamping portion 31 and the bottom plate is adjustable.

[0033] In detail, the second clamping assembly 30 includes a second clamping portion 31 opposite to the bottom plate, and the distance between the second clamping portion 31 and the bottom plate is adjustable. In this way, for battery packs of different heights, the second clamping assembly 30 can fix the battery pack, further improving the versatility for battery packs of different specifications. At the same time, since the distance between the second clamping portion 31 and the bottom plate is adjustable, the second clamping portion 31 can ensure appropriate vertical stress while pressing the battery pack, thereby avoiding damage to the battery pack due to excessive pressure on the battery pack.

[0034] Among them, the distance between the second clamping part 31 and the base plate is adjustable, which means that the height of the second clamping part 31 on the base plate relative to the base plate can be adjusted. The second clamping part 31 is connected to the base plate by means of a gear rack, or by means of a screw nut, or by means of a sliding groove in combination with a fastener 322 to achieve fixation after adjustment, and this application does not impose any restrictions.

[0035] like Figure 1 and Figure 2 As shown, in some embodiments, the first clamping assembly 20 also includes two relatively arranged fixing seats 22, on which the first adjusting member 23 and the second adjusting member 24 are provided, the first adjusting member 23 is also connected to the first clamping portion 21, and the two second adjusting members 24 are respectively connected to the two ends of the second clamping portion 31.

[0036] In detail, the first clamping assembly 20 also includes two relatively arranged fixing seats 22, on which the first adjusting member 23 and the second adjusting member 24 are provided, and the first adjusting member 23 is also connected to the first clamping portion 21, wherein, in this way, the position of the first clamping portion 21 can be adjusted respectively by using the first adjusting member 23, and the second adjusting member 24 can, on the one hand, support the second clamping portion 31 so that the second clamping portion 31 remains balanced, and at the same time, when the second clamping portion 31 presses the battery pack, it can also ensure that the force on the battery pack is more balanced.

[0037] like Figure 1 and Figure 2 As shown, in some embodiments, the distance between the two fixing seats 22 is adjustable, and the second clamping portion 31 includes two sub-clamping portions 311 , and each sub-clamping portion 311 is connected to each second adjusting member 24 .

[0038] Specifically, the distance between the two fixing seats 22 is adjustable, and the second clamping portion 31 includes two sub-clamping portions 311, and each sub-clamping portion 311 is connected to each second adjusting member 24. In this way, when adjusting the distance between the two fixing seats 22, the distance between the two sub-clamping portions 311 can be adjusted. Therefore, when adjusting the two first clamping portions 21 cannot meet the adaptability to the battery pack, by adjusting the positions of the two sub-clamping portions 311 and the fixing seat 22, it is possible to adapt to a wider or longer battery pack. When the length and width of the battery pack do not change much, the battery pack can be adapted by fine-tuning the distance between the two first clamping portions 21. In this way, the distance between the two fixing seats 22 can be adjusted during coarse adjustment, and the distance between the two first clamping portions 21 can be adjusted during fine adjustment, thereby shortening the adjustment stroke, reducing the difficulty of adjustment, and better adapting to battery packs of different specifications.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments, the second clamping assembly 30 further includes at least one pressure strip 32, both ends of the pressure strip 32 are respectively connected to the sub-clamping portion 311 through fasteners 322, and the connection position of the fastener 322 and the pressure strip 32 is adjustable.

[0040] Specifically, the two sub-clamping portions 311 are laterally connected using the pressure strip 32 as the distance between the two fixing seats 22 is adjusted. In this way, the pressure strip 32 can ensure that the battery pack is compressed while reducing the stress in the vertical direction to avoid damage to the battery pack.

[0041] like Figure 1 and Figure 3 As shown, in some embodiments, a slide groove 321 is provided on the pressure strip 32 , and the fastener 322 is clamped in the slide groove 321 .

[0042] In detail, a slide groove 321 is provided on the pressure strip 32, and the fastener 322 is clamped in the slide groove 321. In this way, by loosening the fastener 322, the position of the pressure strip 32 is adjusted to make the fastener 322 move relatively in the slide groove 321, and then the fastener 322 is adjusted to press the pressure strip 32 to fix the pressure strip 32. In this way, the cooperation of the slide groove 321 and the fastener 322 can play a role in positioning and guiding when adjusting the pressure strip 32, simplifying the adjustment structure and ensuring the accuracy of the adjustment direction.

[0043] In some embodiments, the first adjusting member 23 is configured as a first screw, and the first screw is threadedly connected to the fixing seat 22. In this way, by rotating the first screw and adjusting the connection position of the first screw and the fixing seat 22, the position of the first clamping portion 21 can be adjusted, thereby simplifying the structural setting of the vibration test fixture.

[0044] In some embodiments, the second adjusting member 24 is configured as a second screw rod, and the second screw rod is threadedly connected to the fixing seat 22. In this way, by rotating the second screw rod and adjusting the connection position between the second screw rod and the fixing seat 22, the position of the second clamping portion 31 can be adjusted, thereby simplifying the structural setting of the vibration test fixture.

[0045] like Figure 1 and Figure 2 As shown, according to the vibration test fixture of the embodiment of the present application, a first elastic pad 211 is provided on the side close to each other of the first clamping portion 21. It can be understood that the first elastic pad 211 can avoid direct contact between the first clamping portion 21 and the outer shell of the battery pack, and the first elastic pad 211 can play a buffering and protective effect on the battery pack, thereby preventing the outer shell from being squeezed and deformed during the compression process.

[0046] like Figure 1 and Figure 2 As shown, according to the vibration test fixture of the embodiment of the present application, a second elastic pad 312 is provided on the side of the second clamping portion 31 facing the bottom plate. It can be understood that the second elastic pad 312 can avoid direct contact between the second clamping portion 31 and the outer shell of the battery pack, and the second elastic pad 312 can play a buffering and protective role in the battery pack, thereby preventing the outer shell from being squeezed and deformed during the pressing process.
