Description

Technical Field

[0001] This utility model belongs to the field of battery testing technology, and in particular relates to a battery impact resistance testing device. Background Technology

[0002] When a battery is manufactured, it needs to undergo an impact resistance test to simulate the impact that the battery will experience during use, thereby verifying the battery's lifespan.

[0003] Chinese Patent CN220419054U discloses a battery impact resistance testing device. This device places the battery on a tray and a metal ball inside a guide tube. As the metal ball falls, it drops rapidly through the guide tube, precisely impacting the battery on the tray surface. A pull handle and support plate are inserted into the guide groove and annular groove to limit the movement of the metal ball. Several annular grooves provide a scale for adjusting the impact intensity on the battery. However, this device has the following drawbacks: the height adjustment of the metal ball is limited, while the weight of the metal ball is usually fixed, resulting in a narrow range of impact intensity for the battery, leading to poor impact resistance testing results. Therefore, there is an urgent need to research a battery impact resistance testing device to solve these problems. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1 and Figure 5-6 As shown, this utility model is a battery impact resistance testing device, including a horizontally arranged base 1; a clamping mechanism 2 is installed on the upper surface of the base 1; a lifting mechanism 3 is vertically installed on one side of the clamping mechanism 2; a mounting strip 4 is horizontally connected to the lifting mechanism 3; a receiving cylinder 5 corresponding to the clamping mechanism 2 is vertically fixed at the end of the mounting strip 4 away from the lifting mechanism 3, and the receiving cylinder 5 is inserted into the mounting strip 4; a bearing rod 6 is vertically inserted inside the receiving cylinder 5; an impact head 601 with a cylindrical structure is vertically fixed at the lower end of the bearing rod 6; the impact head 601 has a hemispherical structure; multiple counterweight rings 602 are stacked above the impact head 601, and the outer edges of the upper and lower surfaces of each counterweight ring 602 are chamfered; multiple counterweight rings 602 are slidably sleeved on the bearing rod 6; the impact head 601 and the counterweight rings 602 are all clearance-fitted inside the receiving cylinder 5. In use, the battery is clamped onto the base 1 by the clamping mechanism 2. Then, the lifting mechanism 3 drives the housing 5 to move up and down via the mounting strip 4 to adjust the relative distance between the housing 5 and the clamped battery. The number of counterweight rings 602 on the support rod 6 is adjusted according to the magnitude of the impact on the battery. The support rod 6 with the counterweight rings 602 is then inserted into the housing 5. After that, the support rod 6 is released, causing the support rod 6, the impact head 601, and the counterweight rings 602 to fall downwards and strike the clamped battery. This achieves the impact resistance test of the battery, which not only expands the range of impact intensity on the battery but also effectively ensures the impact resistance test effect of the battery.

[0027] Among them, such as Figure 1-2As shown, the clamping mechanism 2 includes a pair of guide rails 201 horizontally bolted to the upper surface of the base 1 and a pair of clamping strips 202 horizontally arranged above the guide rails 201. A pair of transmission blocks 203 are bolted to each of the two clamping strips 202. A slider 204 is bolted to the lower part of each pair of transmission blocks 203. The two sliders 204 on each clamping strip 202 are slidably connected to the two guide rails 201 respectively. A positioning post 206 is vertically inserted into the upper surface of each pair of sliders 204. The lower end of the positioning post 206 abuts against the upper surface of the guide rail 201, and the positioning post 206 is threadedly engaged with the slider 204. In use, the battery is placed between the two clamping strips 202, and manually operated to bring the two clamping strips 202 closer together and clamp the battery. Then, the positioning post 206 is rotated so that the lower end of the positioning post 206 is in tight contact with the upper surface of the guide rail 201, thereby achieving the clamping and positioning of the battery and effectively ensuring the impact resistance test effect of the battery.

[0028] Among them, such as Figure 1 and Figure 3 As shown, the lifting mechanism 3 includes a guide rod 301 vertically bolted to the upper surface of the base 1; a guide sleeve 302 is slidably sleeved on the guide rod 301; a screw 303 is vertically arranged on one side of the guide sleeve 302; the lower end of the screw 303 is rotatably connected to the upper surface of the base 1; a threaded sleeve 304 is threaded onto the screw 303; both the threaded sleeve 304 and the guide sleeve 302 are fixedly inserted into the mounting strip 4. In use, the screw 303 is manually rotated to drive the threaded sleeve 304 to move up and down, thereby moving the mounting strip 4 to move the housing 5 up and down, thus adjusting the relative distance between the housing 5 and the battery.

[0029] Example 2:

[0030] Based on Example 1, as follows Figure 3 As shown, a blocking mechanism 7 is installed on the lower surface of the mounting strip 4; the blocking mechanism 7 includes a mounting block 701 bolted to the lower surface of the mounting strip 4; a push-pull rod 702 parallel to the mounting strip 4 is slidably inserted on the mounting block 701; a blocking plate 703 is horizontally bolted to one end of the push-pull rod 702 away from the lifting mechanism 3; the upper surface of the blocking plate 703 can slide against the lower port of the receiving cylinder 5. In use, by sliding the upper surface of the blocking plate 703 against the lower port of the receiving cylinder 5, the lower port of the receiving cylinder 5 is blocked. Then, the impact head 601 is placed into the receiving cylinder 5, and the push-pull rod 702 is manually operated to separate the blocking plate 703 from the lower port of the receiving cylinder 5, thereby enabling the impact head 601 to move downward from inside the receiving cylinder 5, further ensuring the impact resistance test effect of the battery.

[0031] Example 3:

[0032] Based on Example 2, as follows Figure 3-5 and Figure 7 As shown, the circumferential sidewall of the container 5 is vertically provided with an observation port 501 in the shape of a long strip, which facilitates the tester to observe the position of the counterweight ring 602 inside the container 5; the container 5 is provided with a limiting mechanism 8; the limiting mechanism 8 includes multiple sets of through grooves 801 arranged side by side from top to bottom on the circumferential sidewall of the container 5 and a horizontally arranged movable piece 802; one edge of the movable piece 802 is integrally formed with a pair of side-by-side limiting strips 803; the two limiting strips 803 can slide through any set of through grooves 801; when the limiting strips 803 are inserted into the through grooves 801, the two limiting strips 803 are respectively set on opposite sides of the bearing rod 6, and the upper surface of the limiting strips 803 is in contact with the lower surface of an adjacent counterweight ring 602. In use, according to the required number of counterweight rings 602, the limiting strip 803 is inserted into a corresponding set of through slots 801, so that the counterweight ring 602 located below the movable plate 802 can move downward with the impact head 601, while the counterweight ring 602 located above the movable plate 802 is placed on the movable plate 802, which effectively improves the flexibility of the counterweight ring 602 and ensures the efficiency of the battery impact resistance test.
