DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Refer to the instruction manual Figure 1-7 , a device for detecting the endurance of a lithium battery for a new energy vehicle according to an embodiment of the present invention, such as Figure 1 As shown, it includes a support assembly 1, and a sampling storage mechanism 2 is fixedly installed on the top of the support assembly 1;

[0031] A quantitative sampling mechanism 3 is fixedly installed on the top of the support assembly 1, and a receiving mechanism 4 is fixedly connected to one side of the quantitative sampling mechanism 3. Figure 6 As shown, the top of the quantitative sampling mechanism 3 is fixedly connected with a stirring mechanism 5;

[0032] Reference Figure 6 As shown, the sampling storage mechanism 2 includes a storage barrel 21 fixedly mounted on one side of 101, and the bottom of the storage barrel 21 is connected to a discharge pipe 26, and the quantitative sampling mechanism 3 includes an annular tray 31 arranged at the bottom of the discharge pipe 26, and a connecting frame 32 is fixedly mounted on the top of the annular tray 31 for plugging into the inner cavity of the discharge pipe 26, and a plurality of connecting frames 32 are fixedly mounted on the top of each of the spherical blocking blocks 33 for blocking the inner cavity of the discharge pipe 26. Under normal conditions, the spherical blocking block 33 blocks the connection between the discharge pipe 26 and the storage barrel 21, and is used to block the liquid outlet of the discharge pipe 26 to prevent the electrolyte in the storage barrel 21 from flowing out. When the annular tray 31 is pushed upward, so that the plurality of connecting frames 32 are synchronously moved up inside the discharge pipe 26, and the spherical blocking block 33 is extended upward, a gap can be generated at the connection between the storage barrel 21 and the discharge pipe 26, and then the electrolyte can flow out stably and synchronously. Figure 5 As shown, a support seat 34 is fixedly installed on the top of the support assembly 1, and a reciprocating screw 35 meshing with the annular tray 31 is rotatably installed on the top of the support seat 34, and a motor 36 for driving it to rotate is fixedly connected to the top of the reciprocating screw 35. The purpose of this arrangement is that when the motor 36 is started to rotate the reciprocating screw 35, the annular tray 31 can synchronously drive the connecting frame 32 and the spherical blocking block 33 to move up and down at its outer wall, thereby intermittently opening and closing the inner cavity of the discharge pipe 26, so that the amount of electrolyte discharged is averaged, so that the results of simultaneous detection of multiple samples are more accurate, the overall operation is very simple, and the work efficiency is beneficial to improve, which is more convenient for practical use. Further, referring to Figure 1 As shown, the top of the storage barrel 21 is threadedly connected with a sealing top cover 22, and a vacuum generator 23 is fixedly installed on the top of the sealing top cover 22. One end of the vacuum generator 23 is connected with an exhaust pipe 24 inserted into the inner cavity of the storage barrel 21, and the outer wall of the storage barrel 21 is connected with a feed pipe 25. In actual use, the exhaust pipe 24 is started to allow the vacuum generator 23 to extract the gas inside the storage barrel 21, so that negative pressure is generated inside the storage barrel 21, so that the electrolyte is extracted from the feed pipe 25 into the storage barrel 21 for storage.

[0033] As a further extension of this solution, combined with Figure 2-3As shown, the receiving mechanism 4 includes a first support frame 41 hinged on the outer wall of the annular tray 31, one side of the first support frame 41 is rotatably connected to the second support frame 42, one side of the second support frame 42 is rotatably mounted with a first limit plate 43, and one side of the first limit plate 43 is fixedly mounted with a second synchronous frame 46, combined with Figure 4-5 As shown, one end of the second synchronous frame 46 is fixedly connected to the second limit plate 47, and the outer wall of the second limit plate 47 is rotatably installed with a third support frame 49, and one side of the third support frame 49 is rotatably connected to the fourth support frame 410 hinged to the support assembly 1. The purpose of this arrangement is that under normal conditions, as the annular tray 31 descends as a whole, the first limit plate 43 and the second limit plate 47 move as a whole to the bottom side position of the annular tray 31 and stop. When the annular tray 31 moves up as a whole, the first support frame 41 is synchronously driven to deflect, and the second support frame 42 drives the first limit plate 43 and the second synchronous frame 46, the second limit plate 47 and the third support frame 49 and the fourth support frame 410 to deflect and move as a whole, so that the first limit plate 43 and the second limit plate 47 gradually shift toward the center position of the bottom of the annular tray 31. At the same time, referring to Figure 5 As shown, an arc-shaped magnetic bracket 411 is fixedly installed on one side of the first limit plate 43 and the second limit plate 47, and a magnetic filling dish 412 is magnetically adsorbed on the inner wall of the arc-shaped magnetic bracket 411, so that when the first limit plate 43 and the second limit plate 47 are synchronously offset and docked to the bottom of the annular tray 31 as a whole, the spherical blocking block 33 moves up to expose a gap at the connection between the storage barrel 21 and the discharge pipe 26, and then the flowing electrolyte is promptly collected, and after a certain amount is collected, the connection between the discharge pipe 26 and the sealing top cover 22 is promptly sealed to facilitate subsequent collection and detection.

[0034] Further, see Figure 3 and Figure 5 As shown, a first slide groove 44 is provided on one side of the first limiting plate 43, and a first synchronous frame 45 rotatably installed inside the first slide groove 44 is rotatably connected to the first support frame 41. A second slide groove 48 is provided inside the second limiting plate 47, and the first slide groove 44 is slidably installed in the inner cavity of the second slide groove 48 and is rotatably connected to the fourth support frame 410. The purpose of such a setting is that when the first limiting plate 43 and the second limiting plate 47 are offset, they are limited by the first slide groove 44, so that the movement of the first limiting plate 43 and the second limiting plate 47 is more synchronized and stable, thereby making the reception of the magnetic suction type packaging dish 412 more stable.

[0035] As a further extension of this scheme, refer to Figure 4-5As shown, the stirring mechanism 5 includes a limit-type slide bar 51 fixedly installed on the top of the spherical blocking block 33 in a vertical state, and a plurality of sawtooth plates 52 are fixedly installed on the top of the limit-type slide bar 51. Figure 7 As shown, a limiting ring 53 is fixedly installed on the inner wall of the discharge pipe 26, and a limiting slide rod 51 is slidably installed inside the limiting ring 53. The purpose of such a setting is to ensure that when the spherical sealing block 33 moves up and down, its up and down movement range can be limited by the limiting ring 53, thereby avoiding the problem that when the electrolyte is packaged and taken, the moving position of the spherical sealing block 33 changes, resulting in uneven amount of electrolyte samples obtained each time, which in turn affects the actual detection results.

[0036] Further, see Figure 6-7 As shown, the inner cavity of the storage barrel 21 is fixedly installed with at least two vertically arranged support plates 54, and a first rotating rod 55 is rotatably installed between the two support plates 54. The outer wall of the first rotating rod 55 is fixedly installed with a first gear plate 56 meshing with the sawtooth plate 52. The purpose of this arrangement is to enable the first gear plate 56 to synchronously drive the first rotating rod 55 to rotate as a whole when the spherical blocking block 33 drives the limiting sliding rod 51 and the sawtooth plate 52 to move up and down. The top of the support plate 5 is provided with a second rotating rod 57 rotatably connected to the two support plates 54, and a plurality of fan blades 58 are fixedly installed on the outer wall of the second rotating rod 57. The second rotating rod 57 and one end of the first rotating rod 55 extending out of the support plate 54 are fixedly installed with a second gear plate 59, and the outer walls of the two second gear plates 59 are meshed with a synchronous belt 510. The purpose of such a setting is that when the first gear plate 56 drives the first rotating rod 55 to rotate, the second gear plate 59 can be rotated synchronously, and then combined with the synchronous belt 510, 0, so that the second rotating rod 57 drives the plurality of fan blades 58 to rotate synchronously, thereby stirring and mixing the electrolyte in the inner cavity of the storage barrel 21, avoiding the precipitation of the mixture in the electrolyte, thereby causing the content of the mixture inside the electrolyte to be uneven, and then affecting the problem of the detection result, wherein every two support plates 54 are set as a group with a first gear plate 56, the number of the first gear plates 56 is set to be multiple, and the plurality of first gear plates 56 are arranged in a circular shape with respect to the inner circumferential surface of the storage barrel 21 in an equidistant state, and the sawtooth plates 52 and the first gear plates 56 are arranged in a one-to-one correspondence. The purpose of such a setting is that when the spherical blocking block 33 moves up and down, it can synchronously drive the plurality of sawtooth plates 52 to drive and rotate the first gear plates 56 at the corresponding positions respectively, so that the plurality of second rotating rods 57 and the fan blades 58 in the inner cavity of the storage barrel 21 synchronously rotate and stir in the inner cavity of the storage barrel 21, so that the material inside the storage barrel 21 is stirred more evenly, which is more convenient for actual detection.
