Description

Technical Field

[0001] The utility model relates to the technical field of battery pack vibration test devices, in particular to a fixing structure used for battery pack vibration test and a battery pack vibration test device. Background Art

[0002] Vibration testing is one of the steps in the battery pack safety performance test. During the vibration test, the battery pack needs to be fixed by a fixture so that the structural strength and stability of the battery pack can be evaluated through the vibration test. In addition, the energy storage battery pack is different from the power battery pack (the power battery pack is used on the vehicle and has multiple mounting points for bolts). When fixing it, it is necessary to first limit it, and then fix the side beams of the battery pack with multiple bolts installed around it.

[0003] Existing fixing structures for battery pack vibration testing, such as the utility model patent with authorization announcement number CN217505147U, disclose a power battery module vibration test fixture for mounting the power battery module on a vibration device. The test fixture includes two support parts, which are maintained on the vibration device in a mirror-like manner; each of the support parts includes a support plate detachably fixed to the vibration device, and a pillow part detachably fixed to the support plate; the power battery module is detachably connected across the pillow parts of the two support parts.

[0004] However, such a device still has its limitations. When performing a vibration test on the battery pack, the above fixing structure fixes the battery pack through a detachable connection between the battery pack and the pillow. When installing or removing, it is necessary to disassemble and install multiple bolts around the battery pack. The battery fixing operation is inconvenient and time-consuming, affecting the test efficiency. Utility Model Content

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model provides a fixing structure for battery pack vibration testing, the specific structure is as follows:

[0030] A fixed structure for vibration testing of battery packs, such as Figure 1 As shown, it includes a first clamping part 1 and a second clamping part 2. The gap between the first clamping part 1 and the second clamping part 2 forms a clamping area 3 for clamping the battery pack. One end of the battery pack abuts against the first clamping part 1, and the other end abuts against the second clamping part 2. When in use, the battery pack can be firmly fixed by being clamped between the two clamping parts. Compared with the traditional bolt fixing method, the operation of fixing or removing the battery pack is simpler, which shortens the fixing time of the battery pack and improves the test efficiency.

[0031] In some embodiments, the fixing structure further includes two side clamping portions 4, which are respectively in contact with two sides of the battery pack to limit the movement of the battery pack in the directions on both sides thereof, thereby ensuring the stability of the battery pack during the vibration test.

[0032] The first clamping portion 1, the second clamping portion 2 and the side clamping portion 4 can all be independent components. However, in order to make as few changes as possible to the original battery pack vibration test device to save process, in a specific embodiment, as shown in FIG. Figure 1As shown, the battery pack vibration test device includes a vibration test platform 5 for performing a battery pack vibration test. The vibration test platform 5 is arranged in a ring in a receiving area for receiving the battery pack, and includes at least three abutting surfaces for abutting the battery pack. The three abutting surfaces respectively form a second clamping portion 2 and two side clamping portions 4. The portion of the vibration test platform 5 where the side not abutting the battery pack is located is used to install the first clamping portion 1, so that the first clamping portion 1 and the second clamping portion 2 are arranged opposite to each other, and the gap between the two forms a clamping area 3.

[0033] In some embodiments, the distance between the first clamping portion 1 and the second clamping portion 2 is adjustable (i.e., the width of the clamping area 3 is adjustable), and the fixing structure can fix battery packs of different sizes without replacing different types of fixing tooling, thereby improving the versatility of the fixing structure.

[0034] In order to adjust the distance between the first clamping part 1 and the second clamping part 2, the first clamping part 1 and the second clamping part 2 can be arranged to be movable. In this embodiment, in order to reduce the adjustment process, Figure 1 and Figure 3 As shown, the second clamping part 2 is preferably a fixed element, and the first clamping part 1 includes a fixed mounting member 11 and a clamping member 12 for abutting against the battery pack, and the clamping member 12 is connected to the mounting member 11 through a connecting rod 13; the first section of the connecting rod 13 is fixedly connected to the clamping member 12, and the second section of the connecting rod 13 is movably connected to the mounting member 11, which is used to adjust the position of the clamping member 12 relative to the mounting member 11, thereby completing the adjustment of the width of the clamping area 3. In a specific embodiment, the mounting member 11 is provided with a through hole along the length direction of the connecting rod 13, and the connecting rod 13 is a threaded rod and is sleeved with two nuts 14; the second section of the connecting rod 13 passes through the through hole, and the two nuts 14 are respectively abutted against the two sides of the mounting member 11 along the length direction of the connecting rod 13. When in use, by sliding the connecting rod 13 in the through hole and fixing the connecting rod 13 with the nut 14, the position of the clamping member 12 relative to the second clamping part 2 can be changed, and the width of the clamping area 3 can be adjusted to adapt to the required battery pack specifications.

[0035] In some embodiments, the first section of the connecting rod 13 is detachably fixedly connected to the clamping member 12, so that the clamping member 12 can be replaced as needed. In a specific embodiment, the clamping member 12 is provided with a threaded hole, and the first section of the connecting rod 13 is threadedly connected to the threaded hole. The self-locking force of the thread can ensure the reliability of the detachable connection between the clamping member 12 and the connecting rod 13.

[0036] In some embodiments, Figure 1As shown, the clamping member 12 includes a first abutting plate 121 for abutting against the end of the battery pack. The first abutting plate 121 and the second clamping portion 2 work together to stably fix the two ends of the battery pack. As a further improvement of the above embodiment, Figure 2 As shown, the clamping member 12 also includes a second abutment plate 122 vertically arranged with respect to the first abutment plate 121, and the second abutment plate 122 abuts against the upper part of the battery pack to limit the movement of the battery pack in the vertical direction, which can further improve the fixing stability of the battery pack in the battery vibration test.

[0037] In some embodiments, the fixing structure further includes a mounting plate for mounting the first clamping portion 1, and the mounting plate is detachably fixed to the mounting member 11, so as to ensure that the first clamping portion 1 can be disassembled and replaced without affecting the movable connection of the clamping member 12 relative to the mounting member 11. In a specific embodiment, the vibration test platform 5 forms the mounting plate, such as Figure 1 and Figure 3 As shown, the mounting member 11 and the mounting plate are both provided with a plurality of corresponding connection holes 6, and the mounting member 11 and the mounting plate are detachably fixedly connected by connection bolts passing through the connection holes 6, so as to ensure the connection stability and facilitate the replacement of the first clamping part 1.
