Description

Technical Field

[0001] This utility model relates to the field of energy storage battery testing technology, and in particular to an auxiliary clamping fixture for energy storage battery testing. Background Technology

[0002] Energy storage battery testing is a crucial step in ensuring the normal and safe operation of battery systems. By measuring internal resistance, the degree of battery aging can be assessed. By testing the battery charging and discharging process, it can be confirmed whether the actual capacity of the battery matches the nominal capacity. By measuring the voltage of individual battery cells and strings, it can be determined whether there are problems such as overcharging, over-discharging, and voltage unevenness. During energy storage battery testing, clamping fixtures are required to keep the battery stable.

[0003] A positioning and clamping auxiliary tooling for battery testing is disclosed in patent CN215986192U, including a base. The base is provided with a pair of first clamping blocks arranged facing each other. The bottom end of the first clamping blocks is slidably connected to the base. The base is provided with a first driving member that drives the first clamping blocks to move. The first clamping blocks are provided with a plurality of receiving slots. The receiving slots are provided with second clamping blocks that clamp the battery. The receiving slots are provided with a second driving member that drives the second clamping blocks to move.

[0004] In the above technology, the second driving component is activated, which in turn drives the second clamping block to extend out of the receiving groove, thereby increasing the contact area between the micro battery and the clamping block and improving the stability of the micro battery. However, a large number of energy storage batteries need to be tested, and the energy storage batteries cannot be unloaded in a short time after testing, which will delay the efficiency of subsequent battery testing. Therefore, an innovation is made to this technology. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary clamping fixture for testing energy storage batteries, so as to solve the problem mentioned in the background art that the number of energy storage batteries to be tested is large and the energy storage batteries cannot be unloaded in a short time after testing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary clamping fixture for testing energy storage batteries, comprising a clamping platform, an anti-pressure seat at the bottom of the clamping platform, two auxiliary plates at the top of the clamping platform, an electric push rod on one side of each of the two auxiliary plates, a clamping plate connected to the output shaft of each of the two electric push rods, an L-shaped block on the other side of each of the two auxiliary plates, a guide plate on one side of each of the two L-shaped blocks, extension plates on both sides of each guide plate, a baffle plate between the inner walls of the two extension plates, and a sponge on one side of each baffle plate.

[0007] As a preferred embodiment of this utility model, both sides of the inner wall of the guide plate are bonded with silicone layers, and multiple sponge rods are provided on one side of each of the two clamping plates.

[0008] In a preferred embodiment of this invention, the multiple sponge rods are arranged at equal intervals.

[0009] As a preferred embodiment of this utility model, threaded holes are provided on the other side of both auxiliary plates, and arc-shaped plates are provided on one side of both L-shaped blocks.

[0010] As a preferred technical solution of this utility model, one end of each of the two arc-shaped plates is fixedly connected to both sides of the guide plate, and one side of each of the two L-shaped blocks is provided with a limit bolt, and one end of each of the two limit bolts is connected to the internal threads of two threaded holes.

[0011] As a preferred embodiment of this utility model, the two arc-shaped plates are positioned correspondingly.

[0012] As a preferred embodiment of this utility model, the guide plate is provided with support shafts on both sides, and an auxiliary sleeve is fixedly sleeved on one end of each of the two support shafts. One side of each of the two extension plates is fixedly connected to one side of the two auxiliary sleeves.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model discloses an auxiliary clamping fixture for testing energy storage batteries. It comprises an L-shaped block, a guide plate, a silicone layer, an extension plate, a baffle plate, and sponges. The energy storage battery is placed on the surface of the clamping platform between two clamping plates. Simultaneously, two electric push rods are activated, causing the two clamping plates to move relative to each other. Multiple sponge rods then clamp the sides of the energy storage battery. After battery testing, as the two clamping plates move towards each other, the energy storage battery is manually pushed onto one side of the guide plate. The battery enters the surface of the guide plate, which, due to its tilt angle, continues to transport the battery downwards. The battery is blocked by the baffle plate. The silicone layer and sponges are both soft, reducing the impact force between the battery and these materials as the battery rolls downwards, thus extending their service life.

[0015] 2. This utility model discloses an auxiliary clamping fixture for testing energy storage batteries. By setting limit bolts, an arc plate, a support shaft, and an auxiliary sleeve, one side of the guide plate abuts against the testing table surface. By rotating the two limit bolts in the opposite direction, one end of the limit bolts disengages from the threaded hole, thereby allowing the guide plate and the two auxiliary plates to be removed. The extension plate is connected to the guide plate through the support shaft and the auxiliary sleeve, which ensures the firmness of the guide plate. Attached Figure Description

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for an auxiliary clamping fixture for testing energy storage batteries:

[0023] Example 1:

[0024] like Figure 1-3 As shown, an auxiliary clamping fixture for testing energy storage batteries includes a clamping platform 1. A pressure-resistant seat 3 is provided at the bottom of the clamping platform 1. Two auxiliary plates 2 are provided at the top of the clamping platform 1. An electric push rod 4 is provided on one side of each of the two auxiliary plates 2. The output shafts of the two electric push rods 4 are driven and connected to clamping plates 5. An L-shaped block 7 is provided on the other side of each of the two auxiliary plates 2. A guide plate 10 is provided on one side of each of the two L-shaped blocks 7. Extension plates 14 are provided on both sides of the guide plate 10. A baffle plate 15 is provided between the inner walls of the two extension plates 14. A sponge is provided on one side of the baffle plate 15. When the energy storage battery enters the surface of the guide plate 10, the guide plate 10, due to its inclined angle, can drive the energy storage battery to continue downwards. The energy storage battery is blocked by the baffle plate 15. The silicone layer 11 and the sponge are both relatively soft, which reduces the collision force between the battery and the baffle plate as the energy storage battery rolls downwards, thus extending their service life.

[0025] Example 2:

[0026] Based on Example 1, such as Figure 1 and Figure 4 As shown, one end of each of the two arc-shaped plates 9 is fixedly connected to both sides of the guide plate 10. Each of the two L-shaped blocks 7 is provided with a limit bolt 8 on one side. One end of each limit bolt 8 is connected to the internal thread of each of the two threaded holes. Each of the two sides of the guide plate 10 is provided with a support shaft 12. One end of each support shaft 12 is fixedly fitted with an auxiliary sleeve 13. By rotating the two limit bolts 8 in the opposite direction, one end of each limit bolt 8 is disengaged from the threaded hole, thereby allowing the guide plate 10 and the two auxiliary plates 2 to be removed. The extension plate 14 is connected to the guide plate 10 through the support shaft 12 and the auxiliary sleeve 13.

[0027] Working Principle: Energy storage battery testing is a crucial step in ensuring the normal and safe operation of the battery system. By measuring internal resistance, the aging degree of the battery can be assessed. Testing the battery's charge and discharge process confirms whether the actual capacity matches the nominal capacity. Measuring the voltage of individual cells and strings determines whether there are overcharge, over-discharge, or voltage imbalance issues. During testing, clamping fixtures are used to keep the battery stable. The above technology requires testing a large number of energy storage batteries, and the batteries cannot be unloaded quickly after testing, thus delaying subsequent battery testing efficiency. Therefore, this technology is innovated. When testing an energy storage battery, it is first manually placed on the surface of the clamping platform 1, positioned between two clamping plates 5. Simultaneously, two electric push rods 4 are activated. After the two clamping plates 5 move relative to each other, multiple sponge rods 6 clamp the sides of the energy storage battery. After the battery testing is completed, as the two clamping plates 5 move towards each other, the clamping of the energy storage battery stops, allowing the battery to be moved. The energy storage battery is pushed by a person onto one side of the guide plate 10. The energy storage battery enters the surface of the guide plate 10. Due to the tilt angle of the guide plate 10, the energy storage battery can continue to be transported downwards. The energy storage battery is blocked by the baffle plate 15. The silicone layer 11 and the sponge are both relatively soft, which reduces the collision force between the battery and the two as the energy storage battery rolls downwards, thus extending the service life of both. The energy storage battery can fall to the position of the baffle plate 15 in a short time, saving the time of subsequent energy storage battery inspection and clamping. The battery that has fallen to the position of the baffle plate 15 can be removed by other personnel without affecting the subsequent battery unloading. One side of the guide plate 10 abuts against the inspection table surface. The two limit bolts 8 are rotated in the opposite direction to disengage one end of the limit bolt 8 from the threaded hole, thereby removing the guide plate 10 and the two auxiliary plates 2. The extension plate 14 is connected to the guide plate 10 through the support shaft 12 and the auxiliary sleeve 13, which ensures the firmness of the guide plate 10.
