DETAILED DESCRIPTION

[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figure 1-Figure 8 A test system for detecting new energy battery packs is shown, including a test module, which is used to test the battery pack; an installation module, which is used to install the test module; a conveying module, which is used to convey the battery pack to the test module for testing; an adjustment module, which is used to adjust the position between the battery packs; the conveying module includes a clamping assembly 28 for fixing the battery pack and a conveying mechanism 3 for lifting the clamping assembly 28. The adjustment module is used to make the battery pack move between multiple test modules, thereby improving the test efficiency.

[0033] The test module includes a hood 2, and different test mechanisms may be arranged inside the hood 2, such as an impact test mechanism, a puncture test mechanism, an immersion test mechanism, a high temperature test mechanism, a wear test mechanism, an extrusion test mechanism and a drop test mechanism.

[0034] The mounting module includes a pillar 1 fixedly connected to the bottom of the hood 2, and a support base is provided at the bottom of the pillar 1, which supports the pillar 1 and supports the hood 2. A universal wheel can also be added to the bottom of the pillar 1, and the position of the test mechanism can be changed by changing the position of the pillar 1. In this way, when the clamping assembly 28 rotates in a certain order, different test mechanisms can form different test chains to realize corresponding tests of the battery pack under different test chains.

[0035] The conveying mechanism 3 includes a base 4, the top of the base 4 is rotatably connected to a rotating shaft 5, the outer wall of the rotating shaft 5 is fixedly connected to a sleeve 6, the top of the sleeve 6 is fixedly connected to a connecting plate 16, the outer wall of the connecting plate 16 is fixedly connected to extension arms 17 that are evenly distributed and circumferentially distributed, the end of the extension arm 17 is fixedly connected to an annular plate 18, the inner wall of the annular plate 18 is inserted and slidably connected to a plurality of symmetrical insertion rods 27, the bottom of the insertion rod 27 is fixedly connected to a fixed plate 21, the top of the insertion rod 27 is fixedly connected to a fixed frame 30, and the clamping assembly 28 is arranged on the inner wall of the inner ring of the fixed frame 30, the bottom of the fixed plate 21 is fixedly connected to evenly distributed vertical plates 20, and the bottom of the vertical plate 20 is fixedly connected to a mounting plate 19 A lifting mechanism is arranged below the mounting plate 19, and the lifting mechanism includes a pair of opposite first electric push rods 11 arranged below the annular plate 18, and a top column 12 is fixedly connected to the output end of the first electric push rod 11, and a support platform 13 is arranged outside the top column 12, and a number of top plates 14 corresponding to the annular plate 18 are arranged on the top of the top column 12, and a connecting frame 15 is fixedly connected between the top plates 14, and a socket 38 is opened at the bottom of the hood 2, and a second electromagnet 39 is arranged on the inner wall of the socket 38, and the second electromagnet 39 is magnetically matched with the fixed frame 30, and the annular plate 18 includes a positioning ring 32 that is slidably connected and inserted into the inner wall of the fixed frame 30, and a pair of clamps 35 are arranged on the top of the positioning ring 32.

[0036] The battery pack can be clamped and fixed by adjusting the two clamps 35. For example, the battery pack to be tested is fixed on all the clamping components 28, and the first electric push rod 11 is started to drive the top plate 14 to rise and push the mounting plate 19 to move upward. The insertion rod 27 is pushed by the mounting plate 19 and moves upward synchronously. The fixing frame 30 placed on the annular plate 18 is pushed upward by the insertion rod 27 and is inserted into the inside of the socket 38 when it reaches a certain position. After the second electromagnet 39 is energized, it will adsorb and fix the fixing frame 30. At this time, all the clamping components 28 are located inside the hood 2, and the test mechanism inside the hood 2 can perform corresponding tests on the battery pack. This design realizes the integration of multiple test mechanisms while performing different tests on multiple battery packs at the same time, thereby greatly improving the test efficiency.

[0037] The adjustment module includes a first gear 7 arranged on the outer wall of the rotating shaft 5 and a motor 9 arranged outside the base 4. A second gear 8 is rotatably installed on the top of the base 4, and the second gear 8 is meshed with the first gear 7. A pulley group 10 is arranged between the output end of the motor 9 and the second gear 8. Through the setting of the pulley group 10, the motor 9 can drive the second gear 8 to rotate after being energized. Through the connection with the first gear 7, the rotating shaft 5 is finally driven to rotate by the motor 9, and then the annular plate 18 is rotated around the rotating shaft 5, so that different battery packs are rotated to different test mechanisms by a certain amplitude, and then the next test can be carried out. This design realizes the battery packs to be tested one by one in different test mechanisms with a clockwise or counterclockwise rotation, so that the test efficiency is further improved.

[0038] A pair of guide rod holes 33 are provided on the outer wall of the positioning ring 32, an elastic band 37 is fixedly connected to the inner wall of the guide rod hole 33, a movable plate 36 is fixedly connected to the inner ring of the elastic band 37, a first electromagnet 31 is provided on the inner wall of the fixed frame 30, and the first electromagnet 31 and the positioning ring 32 are magnetically matched, a pair of guide rods 29 are fixedly connected to the top of the fixed plate 21, and the guide rods 29 are slidably connected and inserted into the inside of the guide rod holes 33, a striker block 23 is fixedly connected to the center of the fixed plate 21, and a protruding hole 24 is provided at the center of the striker block 23, a second electric push rod 22 is fixedly installed on the top of one of the mounting plates 19, a contact block 25 is fixedly connected to the driving rod of the second electric push rod 22, and in the initial state, the first electromagnet 31 is energized and generates magnetic force to attract the positioning ring 32 so that the position of the positioning ring 32 can be fixed. After the first electromagnet 31 is powered off, the positioning ring 32 that loses its restraint will slide along the guide rod 29 and finally fall onto the fixed plate 21. During the process, the movable plate 36 will preferentially contact the impact block 23. Due to the elastic properties of the elastic band 37, the spring 26 will pull the elastic band 37 to extend after being hit, and then contact the battery pack above to complete the drop test. After the test, the second electric push rod 22 drives the contact block 25 to rise and push the positioning ring 32 to its original position for the next test. The elastic band 37 can close the gap between the positioning ring 32 and the movable plate 36 to achieve the purpose of sealing. After the positioning ring 32 is inserted into the socket 38, the hood 2 is in a closed state, so that it can safely perform various tests.

[0039] A pair of anti-shock cavities 34 are provided on the inner wall of the positioning ring 32. Counterweights are contained inside the anti-shock cavities 34. The counterweights may be metal balls and metal sheets. When a plurality of counterweights are filled inside the anti-shock cavities 34, when the battery pack falls onto the fixed plate 21, the feedback impact will cause part of the counterweights inside the anti-shock cavities 34 to be vibrated and bounced up, thereby offsetting the impact force to a certain extent, thereby preventing the positioning ring 32 from undergoing multiple small aftershocks under the feedback of the impact force, thereby converting the original drop test into an impact test for the battery pack. It should be noted that the drop test can be restored after the counterweights are removed.

[0040] The outer sleeve of the insertion rod 27 is provided with a spring 26. When the positioning ring 32 moves upward, the spring 26 is compressed and provides resistance to enable the positioning ring 32 to move smoothly. When the positioning ring 32 falls downward, the spring 26 rebounds and can increase the downward falling speed of the positioning ring 32.

[0041] The technical solution provided by the present invention is:

[0042] When the clamping assembly 28 rotates in a certain order, different test mechanisms can form different test chains to enable the battery pack to be tested accordingly under different test chains. The test mechanism inside the hood 2 can perform corresponding tests on the battery pack. This design integrates multiple test mechanisms and can also perform different tests on multiple battery packs at the same time, greatly improving the test efficiency.

[0043] The elastic band 37 can close the gap between the positioning ring 32 and the movable plate 36 to achieve the purpose of sealing. After the positioning ring 32 is inserted into the socket 38, the hood 2 is in a closed state, so that it can safely carry out various tests. When the battery pack falls onto the fixed plate 21, its feedback impact will cause part of the counterweight inside the anti-shock chamber 34 to be vibrated and bounced up, thereby offsetting the impact force to a certain extent, avoiding the positioning ring 32 from having multiple small aftershocks under the feedback of the impact force, thereby converting the battery pack into an impact test in the original drop test, and the drop test can be restored after the counterweight is removed.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
