Detailed Implementation

[0035] The present invention will now be described in further detail with reference to the accompanying drawings.

[0036] This utility model provides an auxiliary device for multi-angle vibration testing of lead-acid batteries, such as... Figure 1-3As shown, the auxiliary device for multi-angle vibration testing of lead-acid batteries (hereinafter referred to as the auxiliary device) includes a first platform 100, a second platform 200, a fixing component 300, an angle holding component 400, and an angle disk 500.

[0037] like Figure 1 and Figure 2 As shown, the first platform 100 is roughly rectangular in shape. The material of the first platform 100 can be steel, stainless steel, or other alloy materials, as long as it is not easily deformed. The plane on the first platform 100 where the battery 10 is placed is roughly square. The first platform 100 is rotatably connected to the second platform 200. Specifically, one end of the first platform 100, that is, one side of the square plane on the first platform 100 where the battery 10 is placed, is rotatably connected to the second platform through a connecting shaft 20, so that the first platform 100 can rotate at any angle relative to the second platform 200 about the connecting shaft 20.

[0038] like Figure 1 and Figure 3 As shown, the second platform 200 is roughly rectangular in shape. The material of the second platform 200 can be steel, stainless steel or other alloy materials, as long as it is not easily deformed. The plane of the second platform 200 facing the first platform 100 is also roughly square. One end of the second platform 200, that is, the side of the square plane of the second platform 200 facing the first platform 100, is rotatably connected to the first platform 100 through the connecting shaft 20.

[0039] It should be noted that, in addition to connecting the first platform 100 and the second platform 200 through the connecting pivot 20, they can also be connected through a hinge. Specifically, the two ends of the hinge can be connected to the first platform 100 and the second platform 200 respectively, so that the first platform 100 can rotate relative to the second platform 200 at any angle with the hinge axis as the pivot.

[0040] like Figure 1 and Figure 2 As shown, the fixing component 300 is disposed on the first platform 100. The fixing component 300 is used to fix the battery 10 to the first platform 100. Specifically, the fixing component 300 includes a first clamping component 310 and a second clamping component 320. The first clamping component 310 is disposed on the plane of the first platform 100 on which the battery 20 is placed, and the second clamping component 320 is also disposed on the plane of the first platform 100 on which the battery 20 is placed. The first clamping component 310 and the second clamping component 320 are opposite to each other and there is a certain distance between them. The battery 10 is placed between the first clamping component 310 and the second clamping component 320. The second clamping component 320 cooperates with the first clamping component 310 to clamp the battery 10 to the first platform 100 to fix the battery 10.

[0041] like Figure 1 and Figure 2 As shown, both the first clamping assembly 310 and the second clamping assembly 320 include a lead screw seat, a lead screw, and a baffle. The lead screw seat, lead screw, and baffle of the first clamping assembly 310 are respectively designated as lead screw seat 311, lead screw 312, and baffle 313. The lead screw seat, lead screw, and baffle of the second clamping assembly 320 are respectively designated as lead screw seat 321, lead screw 322, and baffle 323. Different lead screw seats are arranged opposite each other on the first platform 100, that is, lead screw seat 311 and lead screw seat 321 are arranged opposite each other on the first platform 100 with a certain distance between them. The number of lead screw seats 311 and lead screw seat 321 can be two each. Different lead screws are inserted into different lead screw seats and can move relative to or in opposite directions, that is, lead screw 312 and lead screw 322... Two lead screws are also provided, with lead screws 312 and 322 respectively inserted into lead screw seats 311 and 321. Lead screws 312 and 322 can move relative to lead screw seats 311 and 321 respectively. Different baffles are respectively provided on different lead screws. When the different lead screws move relative to each other, the different baffles abut against the battery to clamp the battery. That is, baffles 313 and 323 are respectively provided on lead screws 312 and 322. When lead screws 312 and 322 move relative to each other, the distance between baffles 313 and 323 gradually decreases until baffles 313 and 323 abut against the sides of the battery 10 to clamp the battery 10 and fix it on the first platform 100. Since lead screws 312 and 322 can drive baffles 313 and 323 to move respectively, it can adapt to the testing needs of various types of batteries, is easy to operate, and is easy to install.

[0042] like Figure 1 and Figure 2 As shown, different lead screws pass through different baffles. The different lead screws are used to limit the battery 10. That is, lead screws 312 and 322 pass through baffles 313 and 323 respectively. Baffles 313 and 323 can rotate relative to lead screws 312 and 322 respectively, but cannot move in the length direction of lead screws 312 and 322. The parts of lead screws 312 and 322 that pass through baffles 313 and 323 respectively can limit the battery 10.

[0043] like Figure 1 and Figure 2As shown, the first platform 100 is provided with at least one set of first through holes 110, each set of first through holes 110 including at least two first through holes 110. The at least one set of first through holes 110 is arranged along the moving direction of the lead screw. At least two first through holes 110 are respectively provided with stop members 120. Different stop members 120 abut against different baffles to prevent different baffles from moving in opposite directions. Specifically, the stop member 120 is a screw. The first platform 100 is provided with multiple first through holes 110, which are divided into multiple groups. Each group of first through holes 110... The first platform 100 has multiple first through holes 110 arranged along the moving direction of the lead screw. When the baffle 313 and baffle 323 respectively abut against the side of the battery 10, one screw is screwed into one of the first through holes 110. The screw abuts against the baffle 313 to prevent the baffle 313 from moving towards the lead screw seat 311. The other screw is screwed into the other first through hole 110. The screw abuts against the baffle 323 to prevent the baffle 323 from moving towards the lead screw seat 321, thereby further fixing the battery 10 to the first platform 100.

[0044] like Figure 1 and Figure 2 As shown, the auxiliary device also includes a first fixing member 600. The first through hole 110 has at least two sets. The first fixing member 600 is disposed in different sets of the first through hole 110 to fix the battery 10 to the first platform 100. Specifically, the first fixing member 600 is a battery mounting strip. After fixing the top of the battery 10, the battery mounting strip extends into the first through hole 110 to fix the battery 10 to the first platform 100. The first fixing member 600 can also be a rope. The rope is wrapped around the battery 10 and then extends into the first through hole 110. The reverse side of the battery 10 is placed on the first platform 100 and knotted to fix the battery 10 to the first platform 100. The direction in which the rope wraps around the battery 10 intersects the direction of the lead screw movement, that is, the surface of the battery 10 wrapped with the rope is perpendicular to the surface of the baffle.

[0045] like Figure 1As shown, the angle holding assembly 400 is connected to the first platform 100 and the second platform 200 respectively. The angle holding assembly 400 is used to maintain the first platform 100 and the second platform 200 at the required rotation angle when the first platform 100 rotates relative to the second platform 200. Specifically, the angle holding assembly 400 includes a support rod base 410, a support rod 420, a support rod sleeve 430, and a fastening assembly 440. The support rod base 410 is disposed on the second platform 200. One end of the support rod 420 is rotatably connected to the support rod base 410, so that the support rod 420 can rotate like the first platform 100. The support rod sleeve 430 is rotatably connected to the first platform 100, and the support rod 420 passes through the support rod sleeve 430. The fastening assembly 440 is disposed on the support rod 420 and fixes the support rod 420 to the support rod sleeve 430. The number of angle holding assemblies 400 can be multiple, such as four, arranged in groups of two on different sides of the first platform 100 (second platform 200).

[0046] like Figure 1 As shown, the fastening assembly 420 includes a first fastener 441 and a second fastener 442. The first fastener 441 is disposed on the support rod 420; the second fastener 442 is disposed on the support rod 420 and cooperates with the first fastener 441 to clamp the support rod sleeve 430. Specifically, the support rod 420 may be threaded. The first fastener 441 and the second fastener 442 are screwed onto the support rod 420. When the first platform 100 rotates, the first platform 100 drives the support rod sleeve 430 to move, so that the support rod sleeve 430 moves in the length direction of the support rod 420. When the first platform 100 rotates to the required angle, by tightening the first fastener 441 and the second fastener 442, the support rod sleeve 430 is clamped between the first fastener 441 and the second fastener 442, so that the support rod sleeve 430 cannot move in the length direction of the support rod 420, thereby keeping the first platform 100 and the second platform 200 at that rotation angle.

[0047] like Figure 1 As shown, the angle disk 500 is set on the second platform 200 and close to the connecting shaft 20. The angle disk 500 is made of transparent material and has a scale. The angle disk 500 is used to observe the angle of rotation of the first platform 100 relative to the second platform 200. That is, the operator can obtain the angle of rotation of the first platform 100 relative to the second platform 200 by observing the scale on the angle disk 500 that coincides with the second platform 200.

[0048] like Figure 1 and Figure 3As shown, the second platform 200 is provided with fixing holes 210. The second platform 210 is fixed to the vibration table (not shown) by a second fastener (not shown) engaging with the fixing holes 210. Specifically, there are multiple fixing holes 210, which are distributed in the middle part of the second platform 200. The vibration table is provided with mating holes. The second fastener can be a screw. The second platform 200 is fixed to the vibration table by inserting the screw into the fixing holes 210 on the second platform 210 and then screwing it into the mating holes on the vibration table.

[0049] like Figure 1 and Figure 3 As shown, the second platform 200 is provided with lightweight holes 220. There are multiple lightweight holes 220. The lightweight holes 220 are square in shape. The lightweight holes 220 are evenly distributed on the second platform 200 and penetrate through the second platform 200. The lightweight holes 220 can effectively reduce the material used in the second platform 200 and reduce the weight of the second platform 200.

[0050] The testing method for lead-acid batteries is as follows:

[0051] The fully charged battery (i.e., battery 10) is fixed on the first platform 100 according to the fixing method guided by the NH engineering drawings (product development), and the vibration angle is adjusted.

[0052] Actual vibration testing requires the vibrator to provide a minimum acceleration of 3.5G and a frequency of 33±2Hz, mainly as follows:

[0053] Vibration testing should be conducted vertically, with three modes of vibration (7 locations and 21 test values) applied to the terminals and the cover surface connected to the internal parts. Required measurements must be between 2.5G and 6G, but at least 7 test points must be above 4.5G. The test is a 24-hour, 3-segment procedure, as follows:

[0054] Place horizontally at 0°±2° for 8 hours

[0055] 8h at an angle of 30°±2° to the short side of the battery

[0056] 8h at an angle of 30°±2° to the long side of the battery

[0057] (When the battery is tilted, the battery terminals are at their lowest point.)

[0058] In an environment of 21.1±2.8℃, the battery undergoes a 24-hour discharge test under vibration. After the test, the battery should meet the 20-hour rated capacity test requirements. Then, the battery assembly is inspected, requiring no obvious mechanical damage, less than 10% loss of active material from the plates, and no damage to the separator. The test is then concluded based on these requirements. Of course, the test method for battery 10 can be modified according to actual needs.

[0059] The auxiliary device of this embodiment, by means of the angle holding component 400, keeps the first platform 100 and the second platform 200 at the required rotation angle when the first platform 100 rotates relative to the second platform 200, thereby adjusting the angle of battery detection and meeting the specific needs of customers.

[0060] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
