Abstract
Description
Technical Field
[0001] The present application relates to the technical field of battery testing equipment, and in particular to a test bench and a test device. Background Art
[0002] Power batteries are an important part of new energy vehicles. In order to ensure driving safety, power battery immersion testing has become the final link for power batteries to enter the market.
[0003] Nowadays, in daily immersion tests in laboratories, a common method for placing a battery pack into water is to use a crane bandage to fix the battery pack and control the crane to lower the battery pack into the water.
[0004] However, on the one hand, the battery pack itself is usually very large in size. When entering the water, the battery pack will shake violently due to the large contact area between the bottom of the battery pack and the water surface. Once the battery pack scratches the inner wall of the puddle during the sinking process, it will cause unnecessary losses. On the other hand, some immersion tests have certain requirements on the depth of the battery submerged in the water and the speed of the battery's descent in the water. The current way of pressing the battery pack with a crane is that its descent speed is affected by the resistance in the water and is difficult to control. In addition, the depth of the battery pack entering the water is difficult to control accurately, which leads to errors in the immersion test. Utility Model Content
[0005] The purpose of the present application is to provide a test bench and a test device to solve one aspect of the prior art to a certain extent. The battery pack itself is usually very large in size. When entering water, the battery pack will be accompanied by very strong shaking due to the large contact area between the bottom of the battery pack and the water surface. Once the battery pack is scratched against the inner wall of the puddle during the sinking process, unnecessary losses will be caused. On the other hand, some immersion tests have certain requirements on the depth of the battery submerged in the water and the speed of the battery descending in the water. The current way of pressing the battery pack with a crane is that its descending speed is affected by the resistance in the water and is difficult to control, and the depth of the battery pack entering the water is also difficult to accurately control, resulting in technical problems such as errors in the immersion test.

[0034] Refer to the following Figures 1 to 3 A test bench and a test device according to some embodiments of the present application are described.
[0035] See also Figures 1 to 3 As shown, an embodiment of the first aspect of the present application provides a test bench, which is arranged in a test pool and is used for immersion testing of battery packs. Specifically, the test bench includes a placement seat 1, a lifting part 2, a connection platform 3, a sensing part and a display part, wherein the placement seat 1 is fixedly connected to the test pool, the connection platform 3 is used to connect to the part to be tested (for example, a battery pack), and the lifting part 2 connects the connection platform 3 and the placement seat 1 to drive the connection platform 3 to rise and fall. The sensing part is arranged on the connection platform 3 to detect the distance between the connection platform 3 and the bottom of the pool. The display part is communicatively connected to the sensing part to display the detection information of the sensing part.
[0036] The test bench provided according to the above technical features is configured to drive the test piece to enter and extend out of the water surface by fixing the mounting seat 1 with the test water pool, and connecting the mounting seat 1 with the connecting platform 3 through the lifting part 2, and providing a sensor on the connecting platform 3 that can monitor the distance between the connecting platform 3 and the bottom of the water pool, and to provide real-time feedback of the distance between the connecting platform 3 and the bottom of the water pool monitored by the sensing part through the display part. On the one hand, the mounting seat 1 is arranged in the test water pool and fixedly connected to the test water pool, which effectively improves the stability of the test bench. Compared with the current push-type water entry method, it effectively reduces the influence of water surface shaking on the stability of the test piece, and reduces the probability of collision between the test piece and the test water pool during the process of the test piece entering and exiting the water; on the other hand, through the real-time monitoring of the sensing part and the real-time feedback of the display part, the tester can timely obtain the distance between the connecting platform 3 and the bottom of the test water pool, and then accurately understand the depth of the test piece submerged in the water, thereby ensuring the accuracy of the immersion test data.
[0037] Preferably, although not shown in the figures, the sensing part may be a distance sensor, but is not limited thereto, and may be other sensors as long as it can detect the depth of the connecting platform 3 entering the water.
[0038] Preferably, although not shown in the figures, the sensing part may be arranged on the side of the connecting platform 3 opposite to the side where the detected component is located, so as to monitor the distance between the connecting platform 3 and the bottom of the test pool.

[0052] In an embodiment, Figure 2 As shown, the number of lifting parts 2 can be equal to the number of legs 11, and the lifting parts 2 and the legs 11 are arranged one-to-one corresponding to each other. In other words, each leg 11 is provided with a lifting part 2 connected to the connecting platform 3 to ensure the lifting stability of the connecting platform 3.
[0053] Optionally, the lifting part 2 can be an electric spring rod, an electric telescopic rod, a pneumatic cylinder, an oil cylinder or other linear drive devices.
