DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0026] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0028] A shock absorbing mechanism and a new energy vehicle battery testing device according to an embodiment of the present application are described below with reference to the accompanying drawings.

[0029] See also Figure 3 and Figure 7 The present application provides a shock absorbing mechanism, including: a shock absorbing part 50.

[0030] The shock absorbing part 50 includes a base 510, a buffer beam frame 520, an arc-shaped beam section 530, a screw rod 540 and a nut 550. The arc-shaped beam section 530 is arranged in the middle section of the buffer beam frame 520, the bottom end of the screw rod 540 passes through the buffer beam frame 520 and is fixed to the base 510, and the nut 550 is screwed and installed with the screw rod 540. A washer 560 is sleeved on the outside of the screw rod 540 between the nut 550 and the arc-shaped beam section 530. Multiple groups of buffer beam frames 520 are distributed in a ring array structure, and the bottoms of multiple groups of buffer beam frames 520 are integrally connected and formed, and the buffer beam frame 520 and the arc-shaped beam section 530 constitute an integrally formed spring plate frame.

[0031] The buffer beam frame 520 is fixed to the base 510 by the cooperation of the nut 550 and the screw rod 540. The base 510 and the table 210 can be fixed and installed by welding or screwing. The buffer beam frame 520 and the arc beam section 530 are both made of metal materials with good toughness. When the sensor assembly is impacted, the multiple groups of buffer beam frames 520 and arc beam sections 530 at the bottom can play a good shock-absorbing and buffering role. The arrangement of multiple groups of buffer beam frames 520 and arc beam sections 530 can mitigate the impact from multiple angles. Compared with the two-side support, it has a better buffering and shock-absorbing effect, and provides buffering protection for the sensor assembly from multiple directions. The arc beam section 530 design of the arc structure makes it easier for the buffer beam frame 520 and the arc beam section 530 to bend as a whole when the integral connection section of the buffer beam frame 520 and the arc beam section 530 is subjected to stamping compression, and has a better buffering effect.

[0032] The present application also provides a new energy vehicle battery testing device.

[0033] See also Figure 1-Figure 6 , Figure 8 and Fig. 9 According to an embodiment of the present application, a new energy vehicle battery detection device includes: a bracket part 10, an impact detection part 20, a lifting magnetic attraction part 30 and an impact part 40.

[0034] Among them, the bracket part 10 is used to support the installation of the impact detection part 20, the lifting magnetic part 30 and the impact part 40. Through the cooperation of the impact detection part 20, the lifting magnetic part 30 and the impact part 40, different degrees of impact tests can be simulated, which has better applicability.

[0035] See also Figure 1 , Figure 2 , Figure 5 and Figure 6The support part 10 includes a frame 110 and a back frame 120, and the back frame 120 can be fixed to the back of the frame 110 by bolts. The impact detection part 20 includes a table 210 and a detection component 220. The table 210 is set on the frame 110, and the detection component 220 is installed in the middle above the table 210. The base 510 is fixedly set with the table 210, and multiple groups of buffer beams 520 are set at the bottom of the detection component 220. The lifting magnetic suction part 30 includes a lifting component 310 and an electromagnet 320. The lifting component 310 is installed on the top of the back frame 120 to drive the electromagnet 320 to move in the vertical direction. The impact part 40 includes a seat frame 410 and an impact block 420. The seat frame 410 is installed in a vertical sliding manner with the back frame 120, and the impact block 420 is installed on one side of the seat frame 410, and the impact block 420 is located directly above the detection component 220, and the top of the seat frame 410 is magnetically adsorbed with the electromagnet 320.

[0036] The working principle of the new energy vehicle battery testing equipment is as follows: the new energy battery to be tested is placed above the testing component 220, and the electromagnet 320 is adjusted to a suitable height through the lifting component 310 according to the needs. At this time, the electromagnet 320 is in a powered state, and the electromagnet 320 can adsorb the seat 410 to drive the impact block 420 to gradually move upward to a specified height in the vertical direction. Then the electromagnet 320 is powered off and loses its magnetic force. Under the action of gravity, the impact block 420 drives the seat 410 to fall vertically until the impact block 420 falls on the battery to be tested. The detection component 220 monitors the impact received, and the test value is displayed through the system and the digital display device. The surface damage of the battery in the collision test can be observed through the surface condition of the battery. Since the battery testing equipment impacts the battery through the impact blocks 420 of different heights to simulate the conditions when different batteries are subjected to different impact forces, it has better simulation applicability, which can make the impact simulation more realistic and the simulated values ​​more accurate.

[0037] In the above specific implementation, please refer to Figure 3 and Figure 4 The table plate 210 includes an end plate 211 and a middle plate 212. The two end plates 211 are respectively fixed at the two ends of the middle plate 212, and the end plates 211 and the middle plate 212 can be integrally formed. The end plates 211 and the frame 110 can be fixedly installed by bolts. The detection component 220 includes a top bottom plate 221, a seat plate 222 and a sensor group 223. The top bottom plate 221 is arranged above the middle plate 212, the sensor group 223 is installed above the top bottom plate 221, and the seat plate 222 is arranged above the sensor group 223. Among them, the sensor group 223 can use a pressure sensor to detect the impact force generated by the impact block 420.

[0038] For specific settings, see Figure 2The impact detection part 20 also includes a limiting assembly 240, which includes a cylinder 241 and a limiting plate 242. The cylinder 241 is installed above the end plate 211, and the limiting plate 242 is set at the output rod end of the cylinder 241. The cylinder 241 in the limiting assembly 240 drives the limiting plate 242 to move in a lateral position, adjusts the gap between the two limiting plates 242, and is used to limit new energy vehicle batteries of various sizes.

[0039] Furthermore, a guide groove 213 is provided on the upper surface of the end plate 211, and a guide block 230 fixedly connected to the limit plate 242 is slidably arranged inside the guide groove 213. The cooperation between the guide groove 213 and the guide block 230 improves the stability of the limit plate 242 when it moves above the end plate 211.

[0040] Specifically, the impact detection part 20 further includes a limit frame 250, which can be fixed by bolts to the upper rear side of the platform 210. The limit frame 250 is used to limit the rear of the placed battery, and through cooperation with the limit assembly 240, ensure that the impact block 420 can accurately impact the middle area of ​​the battery when it falls.

[0041] In the above specific implementation, please refer to Figure 5 The lifting assembly 310 includes a fixed seat 311, a connecting seat 312 and a winch 313. The fixed seat 311 is fixed on the top of the back frame 120, the winch 313 is installed on the top of the fixed seat 311, the electromagnet 320 is installed at the bottom of the connecting seat 312, the connecting seat 312 and the back frame 120 are slidably arranged, and the wire rope of the winch 313 pulls the connecting seat 312 to move in the vertical direction to adjust the height. The winch 313 in the lifting assembly 310 drives the lower connecting seat 312 to adjust the height, that is, adjusts the height of the electromagnet 320, and realizes the adjustment of the release height of the impact block 420 to simulate different impact forces for impact battery detection tests.

[0042] For further information, see Figure 6 The side frame 450 is provided at the side of the seat frame 410, and the adjustment handle 460 is installed on the side frame 450. The adjustment handle 460 can be used to fix the seat frame 410 and the impact block 420 on the back frame 120 by rotating.

[0043] After the impact block 420 falls and impacts the battery surface, the above-mentioned new energy vehicle battery testing equipment is likely to be bounced up and hit the battery to be tested again due to the reaction force of the impact. Although it does not affect the sensor monitoring data, multiple impacts are likely to cause different degrees of damage to the battery surface, affecting the corresponding impact data and the damage state of the battery surface caused by the impact, resulting in inaccurate test data.

[0044] In the above specific implementation, please refer to Figure 6 and Fig. 9, the impact part 40 also includes a positioning shaft 470, a fixing sleeve 480 and a positioning sleeve 490. The impact block 420 is a cylindrical shell structure, and the bottom of the impact block 420 is a planar structure. One end of the positioning shaft 470 is fixed to the frame 410 through the fixing sleeve 480. A positioning bar 471 is arranged outside the positioning shaft 470, and the impact block 420 is sleeved outside the positioning shaft 470, and the two ends of the impact block 420 are respectively fixed and installed through the positioning sleeve 490. A slider 430 is arranged on the back of the frame 410 to slide with the back frame 120. The setting of the slider 430 improves the stability of the frame 410 when it moves along the back frame 120 in the vertical direction, and improves the accuracy of the impact block 420 falling and impacting the test battery to be tested. An inner notch 431 is arranged in the middle of the slider 430, and an installation notch 433 and a liquid inlet channel 432 are respectively arranged inside the slider 430. A hole groove 434 connected to the installation groove 433 is arranged on the inner side of the inner groove 431, a piston block 435 is movably arranged inside the installation groove 433, a push rod 436 is fixed to the front end of the piston block 435, the hole groove 434 movably passes through the hole groove 434, a spring 437 is sleeved on the outside of the push rod 436 section located inside the installation groove 433, the cavity inside the impact block 420 is connected and docked with the liquid inlet channel 432 through the guide tube 610, and the guide tube 610 is installed with an electromagnetic valve 620, a liquid inlet and outlet 630 is arranged on the top of the impact block 420, and a first valve 640 is installed on the liquid inlet and outlet 630.

[0045] The impact block 420 is pre-filled with liquid through the liquid inlet and outlet 630. The secondary liquid can be a non-volatile liquid such as oil. When the seat frame 410 and the impact block 420 move downward together, the solenoid valve 620 is in a closed state. Under the elastic support of the spring 437, the rod end of the push rod 436 is located inside the hole groove 434. When the impact block 420 impacts the battery surface, the sensor group 223 quickly opens the solenoid valve 620 through the cooperation of the control system. While the oil inside the impact block 420 is impacted, the liquid inside the impact block 420 will be quickly pressurized upward. The upward pressurized liquid enters the liquid inlet channel 432 through the guide tube 610. The oil entering the liquid inlet channel 432 enters the installation slot 433 to squeeze the piston block 435 and the spring 437, causing the rod end of the spring 437 to protrude from the hole groove 434 and contact the back frame 120, that is, in an instant, the slider 430 will not move relative to the back frame 120 under the strong friction force. That is, the impact block 420, after being punched to the surface of the battery, will not recoil and move to impact the battery surface again. Afterwards, the handle on the side of the frame 410 can be pushed to push the frame 410 and the impact block 420 upward a certain distance, and then the impact block 420 and the frame 410 can be locked and fixed to the front side of the back frame 120 by adjusting the handle 460, and the frame 410 can be adsorbed again by lowering the lifting assembly 310 and the electromagnet 320, and the test battery to be tested is replaced to prepare for the next test. This technical solution can ensure that the impact data obtained when the impact block 420 impacts the battery surface is consistent with the degree of damage to the battery surface, further improving the data accuracy of the detection test when the new energy battery is impacted.

[0046] Among them, the slider 430 preferably adopts at least four groups, which can not only improve the accuracy of the seat frame 410 when moving in the vertical direction, but also the ends of the multiple push rods 436 in the slider 430 quickly protrude to quickly fix the seat frame 410. The push rod 436 can be made of a rubber material with greater friction, and the protruding push rod 436 can continue to be used even if a certain amount of wear occurs to achieve the purpose of frictional deceleration.

[0047] If the impact height can be adjusted to change the impact force, and the impact mass of the impact block 420 can also be adjusted, the impact force can be adjusted in a wider range, and test data in a wider range can be obtained.

[0048] See also Fig. 9The impact block 420 has two partitions 710 disposed in the internal cavity, and a flexible ring belt 720 is disposed between the two partitions 710 to enclose a gas storage cavity. A gap is left between the bottom of the partition 710 and the bottom wall inside the impact block 420, and the liquid storage cavity is formed between the partition 710, the outer wall of the flexible ring belt 720, and the inner wall of the flexible ring belt 720. A gas inlet and outlet 730 connected to the gas storage cavity is disposed on the top of the impact block 420, and a second valve 740 is disposed on the gas inlet and outlet 730. The partition 710 is slidably sleeved outside the inner cylinder of the flexible ring belt 720.

[0049] The impact force regulation can be changed by changing the ratio between the gas storage cavity and the liquid storage cavity inside the impact block 420. The specific adjustment method is: inject an appropriate amount of gas into the gas storage cavity enclosed between the internal partition 710 and the flexible ring belt 720 of the impact block 420 through the gas inlet and outlet 730 and the second valve 740. The partition 710 between the flexible ring belt 720 will expand according to the pressure of the internal gas, and the excess liquid in the liquid storage cavity inside the impact block 420 can be discharged through the liquid inlet and outlet 630 and the first valve 640 until the impact block 420 is at a suitable weight as a whole, so that the impact block 420 can have different gravity impact batteries to obtain detection test data, further improving the acquisition range of battery detection test data.

[0050] This adjustment method can change the weight of the liquid inside the impact block 420 , and when the impact block 420 impacts the battery, it will not affect the pressure of the liquid inside the impact block 420 flowing into the liquid inlet channel 432 through the guide tube 610 .

[0051] It should be noted that the specific model specifications of the above-mentioned winch 313, solenoid valve 620, and sensor group 223 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail. The power supply and principle of the winch 313, solenoid valve 620, and sensor group 223 are clear to those skilled in the art and will not be described in detail here.
