[0043] The technical solutions 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 only 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 those skilled in the art without making creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; and "inside" and "outside" refer to the outline of the device.

[0044] Battery pack vibration testing is a process used to evaluate the performance and reliability of batteries under vibration conditions to ensure that the batteries can withstand vibration loads in actual use environments without failure. Figure 1-Figure 3 , Figure 1 This is a structural diagram of a vibration test tool provided in an embodiment of the present application. Figure 2 yes Figure 1 The enlarged schematic diagram of part A of the vibration test fixture is shown. Figure 3 yes Figure 2 The structural schematic diagram of the first stopper shown. The present application provides a vibration test fixture 100, which includes a base plate 10, two first stops 20 and a first fastener. The base plate 10 is used to place the battery pack, and the base plate 10 is provided with a plurality of fixing holes 11. The two first stops 20 are relatively clamped on both sides of the battery pack, wherein at least one first stopper 20 is provided with a first strip opening 201, and the first strip opening 201 is provided corresponding to at least one of the fixing holes 11. Among them, the two first stops 20 can be arranged along the first direction, and the first strip opening 201 can extend along the first direction. The first fastener can be passed through the fixing hole 11 and the first strip opening 201, and fixedly connect the first stopper 20 and the base plate 10. The first fastener can be a screw, a screw, a screw, etc., which is not limited in the present application.

[0045] The vibration test fixtures 100 of the existing production lines mostly use an integrated mechanism of a vibration table and a vibration machine. It is difficult to operate and difficult to move, which is more affected by the site. The battery pack must be moved to the fixture before the vibration test can be carried out. However, the design of the existing integrated vibration testing equipment is too simple and cannot adapt to the fixation of battery packs of various models. Under the premise of an endless stream of various products on the production line, the disadvantages of the existing test fixtures are becoming more and more obvious. The present application provides a plurality of fixing holes 11 on the bottom plate 10, and two first stoppers 20 are relatively clamped on both sides of the battery pack, wherein at least one of the first stoppers 20 is provided with a first strip-shaped opening 201. Since the first strip-shaped opening 201 corresponds to at least one of the fixing holes 11, when the stoppers are used to fix the battery pack on both sides, the fixing hole 11 corresponding to the first strip-shaped opening 201 can be quickly found to fix the stoppers, so as to adapt to the fixation requirements of battery packs of different models and improve the fixation efficiency of battery packs of different models.

[0046] Furthermore, existing integrated vibration test fixtures are difficult to operate and difficult to move, often affected by the site. The battery pack must be moved to the fixture before vibration testing can be performed, requiring the battery pack to be moved using a crane. This also presents significant challenges in moving the battery pack. However, the present invention can accomplish this by simply moving the base plate 10 beneath the battery pack, further accelerating testing efficiency.

[0047] In some embodiments, each first stop member 20 includes a first baffle 21 and a first fixing plate 22. The first fixing plate 22 is fixed to the base plate 10. The first fixing plate 22 is provided with the first strip-shaped opening 201. The first baffle 21 is connected to the first fixing plate 22 and extends away from the base plate 10. The first baffle 21 is used to abut the battery pack.

[0048] In some embodiments, the first stopper 20 further includes at least one first reinforcing rib 202 , and the first reinforcing rib 202 is connected between the first baffle 21 and the first fixing plate 22 .

[0049] In some embodiments, a plurality of circular holes corresponding to the fixing holes 11 may be provided on the stopper, and the fixing holes 11 and the holes on the stopper may correspond one to one, and the fastener may be passed between the fixing holes 11 and the first strip opening 201 .

[0050] Specifically, the first reinforcing rib 202 may be a trapezoidal structure, with one right-angled side of the trapezoidal structure connected to the first baffle 21 and the other right-angled side of the trapezoidal structure connected to the first fixing plate 22. The first reinforcing rib 202 may also be a right-angled triangular structure, with one right-angled side of the triangular structure connected to the first baffle 21 and the other right-angled side of the triangular structure connected to the first fixing plate 22.

[0051] In some examples, there is one first reinforcing rib 202 , and the first reinforcing rib 202 is disposed in the middle of the first stopper 20 .

[0052] In some examples, there are multiple first reinforcing ribs 202, such as two, three, or four. Multiple first reinforcing ribs 202 are spaced apart between each first baffle 21 and the first fixing plate 22. Correspondingly, the first strip-shaped openings 201 can be spaced apart on the fixing plate, such as two or three. The number of first reinforcing ribs 202 and first strip-shaped openings 201 is not limited in this application.

[0053] Please refer to Figure 4-Figure 6 , Figure 4 yes Figure 1 The top view of the vibration test fixture is shown. Figure 5 yes Figure 4 The structural diagram of the front stopper shown in FIG. Figure 6 yes Figure 4 The schematic structural diagram of the rear stopper is shown.

[0055] Specifically, the first direction may be a direction parallel to the short side of the battery pack, and the second direction may be a direction parallel to the long side of the battery pack. The first stopper 20 is provided on both sides of the long side of the battery pack, and the second stopper 30 is provided on both sides of the short side of the battery pack to fix the battery pack from all sides to prevent the battery pack from detaching from the base plate 10 due to inertia and causing unnecessary losses.

[0056] In some embodiments, the second stopper 30 includes a front stopper 31 , and an escape space is formed between the front stopper 31 and the front end wall to avoid parts of the front end wall of the battery pack.

[0058] As will be appreciated, the front end of the battery pack is provided with protruding components such as the MSD, fuse, and maintenance cover handle. Multiple protrusions 313 are spaced apart on the front baffle 311 to provide clearance for the components at the front end of the battery pack, thereby preventing interference between the front baffle 311 and the components at the front end. The number of protrusions 313 and the size of the clearance can be adjusted based on actual conditions. In actual applications, other structures such as protruding plates and cams may also be provided, but this application does not limit this.

[0059] In some embodiments, the front baffle 311 is provided with a plurality of mounting holes 314 , and the protrusions 313 are detachably mounted in different mounting holes 314 .

[0060] Specifically, the protrusion 313 is provided with a mounting structure corresponding to the mounting hole 314. One protrusion 313 can be mounted in one mounting hole 314, or in multiple mounting holes 314. By adjusting the mounting position of the protrusion 313 on the front bezel 311 according to the distribution of components on the battery pack, interference with different battery pack structures can be further avoided by the front stopper 311.

[0061] In some embodiments, the second stop member 30 includes a rear stop member 32, and the rear stop member 32 includes a rear baffle 321 and a rear fixing plate 322.

The rear baffle 321 is provided with an anti-foolproof opening 323, and the anti-foolproof opening 323 is used to expose components of the rear end wall of the battery pack.

[0062] It is understandable that a socket for a communication line may be provided at the rear end of the battery pack. Providing an anti-mute opening 323 can better help users distinguish the front and rear ends of the battery pack, avoid installing the front baffle 311 at the position of the socket, reduce errors caused by improper user operation, and improve the safety and reliability of the device or system.

[0063] In some embodiments, the second stop member 30 also includes at least one second reinforcing rib 302, at least one second reinforcing rib 302 is connected between the front baffle 311 and the front fixed plate 312, and at least one second reinforcing rib 302 is connected between the rear baffle 321 and the rear fixed plate 322.

[0064] In some examples, there are two second reinforcing ribs 302 , one second reinforcing rib 302 is disposed in the middle of the front stopper 31 , and the other second reinforcing rib 302 is disposed in the middle of the rear stopper 32 .

[0065] In some examples, there are multiple second reinforcing ribs 302, such as two, three, four, etc., some of the second reinforcing ribs 302 are spaced apart between the front baffle 311 and the front fixed plate 312, and some of the second reinforcing ribs 302 are spaced apart between the rear baffle 321 and the rear fixed plate 322, and the second reinforcing ribs 302 and the second strip opening 301 are adjacent to each other.

[0066] When both the front stopper 31 and the rear stopper 32 are provided with second reinforcing ribs 302 , the number of the second reinforcing ribs 302 can be set according to actual conditions, and this application does not limit this.

[0067] In some examples, the second stopper 30 further includes at least one second reinforcing rib 302 , and at least one second reinforcing rib 302 is connected between the front baffle 311 and the front fixing plate 312 , or at least one second reinforcing rib 302 is connected between the rear baffle 321 and the rear fixing plate 322 .
