[0054] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0055] These descriptions are intended to be exemplary only, and are not intended to limit the scope of the invention.

[0056] A storage battery safety detection device provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0057] Embodiment 1:

[0058] Combination Figure 1-Figure 13 As shown, the present invention provides an energy storage battery safety detection device, comprising four groups of suspended calibration mechanisms 400, energy storage battery groups 500 arranged in the four groups of suspended calibration mechanisms 400, partition simulation mechanisms 200 arranged outside the four groups of suspended calibration mechanisms 400, medium input mechanisms 300 arranged on the partition simulation mechanisms 200, test power lines 600 arranged in the partition simulation mechanisms 200, and mimicry mechanisms 100 arranged outside the partition simulation mechanisms 200 and placed on the ground, the mimicry mechanisms 100 are used to provide multi-angle mimicry adjustment for the energy storage battery group 500, the partition simulation mechanisms 200 are used to provide a multi-medium detection environment for the energy storage battery group 500, the medium input mechanism 300 is used to input different media to be tested, and is used to provide simulated conditions for the energy storage battery group 500, the suspended calibration mechanisms 400 are used to provide a central fixed platform for the inverted energy storage battery group 500, and the test power lines 600 are used to detect the output current performance of the energy storage battery group 500 in the mimicry state.

[0059] The simulation mechanism 100 includes two ground-mounted bases 110, a positioning assembly 120 disposed between the two bases 110, and two arc rails 130 movably mounted in the two bases 110, and a support column 140 is fixedly mounted on the inner side of the arc rail 130, and an outer frame plate 150 is mounted on the two support columns 140, which is used to provide multi-angle simulation adjustment for the partition simulation mechanism 200 as a whole;

[0060] The outer frame plate 150 is composed of two U-shaped frames and an H-shaped top plate, and two return springs 160 are arranged at the bottom of the U-shaped frame, and four symmetrically distributed cantilevers 170 are arranged on the U-shaped frame, and a deflection joint 180 is movably installed on the cantilever 170, and a high-frequency striker 190 is movably installed in the middle of the H-shaped top plate;

[0061] The arc track 130 has evenly distributed holes inside;

[0062] The top end of the support column 140 is installed inside the U-shaped frame;

[0063] The partition simulation mechanism 200 includes a sealed housing 210 disposed in the middle of the inner side of the outer frame plate 150, a first sealing door 250 is movably mounted on one end of the sealed housing 210, and a horizontal anti-overflow pad 270 is mounted in the middle of the inner side of the first sealing door 250;

[0064] The inner wall of the sealed housing 210 is provided with two sets of partition pads 240 which are symmetrically distributed;

[0065] Four sets of suspended calibration mechanisms 400 are respectively arranged at the top and bottom of the inner cavity of the sealed housing 210, and are used to cooperate with the two partition pads 240 to provide a centrally fixed platform for the energy storage battery pack 500;

[0066] The test power line 600 is connected to the interface of the energy storage battery pack 500, and cooperates with the current detection equipment to detect the real-time output current performance of the energy storage battery pack 500.

[0067] At present, the main tests for energy storage batteries are battery capacity test, battery cycle life test, battery safety test and battery environmental adaptability test. These four main test methods need to be tested separately in situations where they fail. However, the separate testing method cannot measure the actual operating status of the energy storage battery in actual situations. Therefore, the actual performance of the energy storage battery in the actual environment cannot be effectively tested.

[0068] The device provides a simulated environment for the energy storage battery, and locks the four ends of the energy storage battery pack 500 through four groups of suspended calibration mechanisms 400 arranged at the top and bottom of the inner cavity of the sealed shell 210, until the energy storage battery pack 500 as a whole is kept centered in the middle of the inner cavity of the sealed shell 210, and two groups of partition pads 240 arranged on the inner wall of the sealed shell 210 respectively limit the top and bottom of the two sides of the energy storage battery pack 500. As the partition plate 340 is inserted from the inside of the second sealing door 310 until the two panels of the second sealing door 310 are clamped along the middle of the two sides of the energy storage battery pack 500, the anti-overflow pad 270 blocks the two panel ends, and the inner cavity of the sealed shell 210 can be divided into two independent cavities. At this time, the two parts formed after the energy storage battery is fixed can simulate the state of assembly in the device;

[0069] After the first medium input box 350 and the second medium input box 360 input different mediums into the inner cavity of the sealed shell 210, the different mediums can be input into the two separated cavities, and then a suitable frequency is selected to control the high-frequency striker 190. The high-frequency striker 190 under vibration can drive the sealed shell 210 to vibrate as a whole. At the same time, the inclined frame 220 cooperates with the deflection joint 180 and the cantilever 170 to flip in coordination. The energy storage battery pack 500 located in the middle of the inner cavity of the sealed shell 210 can simulate the state of being bumped on different roads, accompanied by the interference of different media on two parts of the energy storage battery pack 500. At this time, the external power supply detection equipment connected to the test power line 600 can accurately detect the real-time current output by the energy storage battery pack 500 in this state.

[0084] Preferably, the threaded section of the extended screw 330 is adapted to engage with the screw hole inside the threaded gasket 230, and the two extended screws 330 are controlled to rotate clockwise. At this time, the two locks 320 and the partition plate 340 form a whole that can clamp the side of the energy storage battery pack 500, and cooperate with the anti-overflow pad 270 to press the two surfaces of the partition plate 340.

[0089] Embodiment 4:

[0090] Combination Figure 10-13 As shown, in the above embodiment, the suspended calibration mechanism 400 includes a load-bearing pile 410 arranged on the sealed housing 210, a positioning plate 420 is installed at the other end of the load-bearing pile 410, a fixed screw rod 430 is installed in the middle of the positioning plate 420, a propulsion rod 440 is arranged on the fixed screw rod 430, and a support plate 450 is movably installed at the bottom end of the propulsion rod 440;

[0091] Two symmetrically distributed traction plates 460 are movably mounted at both ends of the support plate 450, a first clamp 470 is movably mounted on one of the traction plates 460, and a second clamp 480 is movably mounted on the other traction plate 460;

[0092] The positioning board 420 is composed of a motherboard and two daughterboards.

[0093] Preferably, two load-bearing piles 410 are fixed to the sealed shell 210 by bolts and gaskets. At this time, the fixed positioning plate 420 can provide effective extension limit pressure for the first clamp 470 and the second clamp 480. With the restraint of the first clamp 470 and the second clamp 480 by the two partition pads 240, the energy storage battery pack 500 can be clamped in the center. At this time, the fixed energy storage battery pack 500 can be located at the center of the inner cavity of the sealed shell 210 to facilitate interference detection of different media.

[0094] The inner walls of the first clamp 470 and the second clamp 480 are both provided with rectangular insertion holes, and the two sub-boards are adapted to penetrate into the two rectangular insertion holes;

[0095] A rotating wheel is installed at the top of the propulsion rod 440 , and a cylindrical cavity is opened inside the propulsion rod 440 , while a screw hole adapted to the threaded section of the fixing screw rod 430 is opened at the bottom of the propulsion rod 440 .

[0096] Preferably, the push rod 440 is movably installed in the hole inside the sealing shell 210. According to the requirement of not passing the medium detection, a rubber gasket needs to be set in the hole inside the sealing shell 210. By adapting the rubber gasket to the push rod 440, the outflow of the medium during the extension of the push rod 440 can be avoided.

[0097] Working principle and use process of the present invention: Energy storage battery safety testing is an important link to ensure the safety and reliability of the battery during use, mainly including appearance testing, size and weight testing, battery capacity testing, charge and discharge performance testing, cycle life testing, overcharge and over discharge testing, short circuit testing, high temperature and low temperature testing, environmental adaptability testing, etc.

[0098] The above-mentioned detection methods are aimed at the charging and discharging stability and pressure resistance of the battery, but these detection methods still have certain defects. When different types of energy storage batteries are used in different devices, these devices are operated in different external environments, different road surfaces and areas with different dryness and humidity. Temperature, humidity and pressure shocks are all generated at the same time, so the detection effectiveness is low;

[0099] The device provides an inherent simulated space for the energy storage battery. When the energy storage battery pack 500 is clamped by the four sets of suspended calibration mechanisms 400 and suspended in the middle of the inner cavity of the sealed shell 210, the energy storage battery pack 500 placed upright or inverted can be divided into two parts to be tested under the central partition of the four partition pads 240, the partition plate 340 and the anti-overflow pad 270. After the first sealing door 250 is closed at the port at one end of the sealed shell 210, the latch 280 can quickly fix the first sealing door 250, and the second sealing door 310 will cooperate with the partition plate 340 to provide pressure-bearing closure for the other end of the sealed shell 210. At this time, the four air ducts arranged in the second sealing door 310 and stacked in the vertical direction with the first medium input box 350 and the second medium input box 360 can extend into the space behind the two partitions respectively.

[0100] At this time, the energy storage battery pack 500 is tested in the vertical direction. After the first medium input box 350 and the partition plate 340 input the hot and cold airflows into the two partitioned spaces respectively, the two separated parts of the energy storage battery pack 500 can be acted upon by the hot and cold airflows separately. When the high-frequency striker 190 is in high-frequency lifting and lowering activity, the two clamping seats arranged in the middle of the top surface of the sealed shell 210 can vibrate in coordination with the high-frequency striker 190. At this time, the sealed shell 210 as a whole can be located at the center position of the inner side of the outer frame plate 150 for high-frequency vibration. At this time, the energy storage battery pack 500 can simulate the performance under the normal external environment according to the selected input of the hot and cold airflows. Then, the test power line 600 is connected to the current detection device. At this time, the real-time detection status of the energy storage battery pack 500 can be displayed by the current detection device.

[0101] When it is necessary to simulate the device in a curved or flipping state for detection, based on the above operation, the slider 122 is pre-adjusted to be pushed outward along the slideway inside the pad 121, and the plug 124 installed on the top of the slider 122 will be withdrawn from one of the arc tracks 130, and then the two arc tracks 130 are controlled to flip sideways along the two bases 110. At this time, the energy storage battery pack 500 in the suspended arrangement can simulate the real-time state of the device in the external place according to the above regulation;

[0102] In addition, the inverted energy storage battery pack 500 can also be subjected to a drop compression test of the uniformly distributed batteries therein during the above-mentioned testing process. According to the testing requirements of the two partitions of the sealed cavity in the sealed housing 210, the first medium input box 350 and the second medium input box 360 can input the corresponding medium to be tested. By testing the two parts of the energy storage battery pack 500 separately with different media, it can be effectively ensured whether the overall packaging part of the energy storage battery pack 500 meets the standards.

[0103] The above detection method only provides multi-state mimicry for the energy storage battery. According to the battery detection steps and detection items, the device can cooperate with the detection steps and detection items.

[0104] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the claims and their equivalents.
