Description

Technical Field

[0001] This invention belongs to the field of battery box testing technology, and in particular relates to a mechanical performance testing device for new energy battery boxes. Background Technology

[0002] Battery box testing is a crucial step in ensuring its safety, reliability, and performance stability. It covers multiple aspects, including structural safety testing, environmental adaptability testing, electrical performance testing, and sealing and durability testing. Structural safety testing further includes mechanical strength and impact resistance testing.

[0003] Currently, after battery boxes are manufactured, they are typically subjected to impact tests using collision testing equipment to simulate real-world collision scenarios and directly assess the battery's safety performance. However, existing battery box mechanical performance testing equipment has some significant shortcomings: Firstly, existing testing equipment performs poorly in the battery box transportation and securing process. On the one hand, it lacks a flexible and precise positioning method during battery box transportation; on the other hand, the battery box is not securely secured enough, making it prone to shaking. These problems will adversely affect the accuracy of the test results.

[0004] Secondly, there are numerous specifications and models of new energy battery boxes, and existing testing equipment has shortcomings in adaptability and versatility. Faced with the testing needs of battery boxes of different specifications, existing equipment often cannot flexibly adjust itself and its fixing devices, and often requires specially designed and replaced test fixtures for different battery boxes. This not only increases testing costs but also prolongs testing time.

[0005] In summary, existing battery box mechanical performance testing equipment suffers from problems such as inflexible and inaccurate transport and positioning, unstable fixing, and insufficient adaptability and versatility. Summary of the Invention

[0006] This invention provides a mechanical performance testing device for new energy battery boxes, which can solve at least one of the problems existing in the mechanical performance testing devices for battery boxes in the prior art.

[0007] To achieve the above objectives, according to an embodiment of the first aspect of the present invention, a mechanical performance testing device for a new energy battery box is provided, comprising a test platform and a frame, wherein the frame comprises a pair of columns fixed on the test platform and a side frame; The impact plate is movably mounted on a pair of columns, and a set of impact components are fixedly installed on the bottom surface of the impact plate by fixing bolts; The winch assembly, mounted on the frame, is used to lift the impact plate; Also includes: The conveyor is fixedly embedded in the test bench. A conveyor seat is slidably installed inside the port of the conveyor. A battery box fixing mold is installed on the conveyor seat for limiting the placement of the battery box. The battery box fixing mold includes a pressure plate, corner limiting brackets at the four corners of the pressure plate, a limiting frame fixed to the inside of the four corner limiting brackets, and an adjustable plate structure on the limiting frame. The adjustable plate structure is used to adapt and fix battery boxes of different specifications. A conveyor positioning mechanism for the linear conveying of the conveyor seat; The vacuum adsorption lifting mechanism is used for adsorption, fixation, and lifting of the battery box fixing mold.

[0008] A further improvement is that the conveying and positioning mechanism includes a rack that is fixedly connected to both sides of the conveying seat and a pair of DC servo motors that are fixedly connected to the test platform and located on both sides of the conveying platform. The main shafts of the DC servo motors are all fixedly connected to synchronous gears, and each synchronous gear and each rack are meshed together.

[0009] A further improvement is that the surface of the conveyor seat is provided with an installation groove, in which a silicone pad with an annular adsorption magnetic plate is embedded. The bottom edge of the pressure plate is fitted with a magnetic sheet corresponding to the annular adsorption magnetic plate, and the two work together to form a magnetic attraction fixing structure. The silicone pad and the middle of the pressure plate are provided with a through opening for the vacuum adsorption lifting mechanism to pass through.

[0010] A further improvement is that each of the columns is fitted with a buffer spring, and the bottom surface of the buffer spring is fixedly installed on the test platform.

[0011] A further improvement is that the vacuum adsorption lifting mechanism includes a pair of miniature lifting cylinders fixedly connected to the conveyor seat, a mounting plate fixedly connected to the top surface of the rod of the miniature lifting cylinder, a vacuum silicone suction cup fixedly embedded in the four corners of the mounting plate, an air path control valve fixedly connected to the bottom surface of each vacuum silicone suction cup, and a vacuum pump fixedly connected to the side of the conveyor table.

[0012] A further improvement is that the vacuum adsorption lifting mechanism also includes a linkage adsorption structure. A groove is opened downward in the middle of the port of the conveying table. The linkage adsorption structure includes a slide seat that is slidably disposed in the groove, a T-shaped support plate that is fixedly connected to the top surface of the slide seat, a pair of vacuum silicone suction cups two that are fixedly embedded in the T-shaped support plate, and a gas path control valve two that is fixedly connected to the bottom end of each vacuum silicone suction cup two. The air pipeline of the vacuum pump is connected to the gas path control valve one and the gas path control valve two.

[0013] A further improvement is that the conveying and positioning mechanism also includes a mounting rod fixedly connected to the inner wall of one side of the trench port. The height of the mounting rod is lower than the height of the trench opening. A set of elastic touch switches is fixedly installed on the mounting rod. A contact block is fixedly connected to the T-shaped support plate on the side facing the mounting rod. The elastic touch switches are connected to indicator lights, which are fixedly installed on the test bench. When all the elastic touch switches are triggered in sequence, the indicator lights show that the conveyor has arrived at the test position.

[0014] A further improvement is that each of the corner limiting brackets has an L-shaped structure and is integrally formed with the pressure plate. A limiting frame is fixedly installed on the inner side of the four corner limiting brackets, and the four corners of the limiting frame are fixedly connected to each corner limiting bracket by fixing bolts.

[0015] A further improvement is that the adjustable plate structure includes an adjustable partition disposed inside the limiting frame, and adjustable slide grooves are provided through both sides of the limiting frame symmetrically, with a locking component movably disposed in each adjustable slide groove; Each of the aforementioned components consists of a stud and a fastening sleeve threaded onto the stud. One end of each of the two studs is fixedly connected to both sides of the adjustable partition.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) The testing scheme of the present invention involves placing the battery box to be tested on the mold, with its four corners inserted into the four corner limiting brackets, and then placing the entire mold along with the battery box into the mounting groove. At this time, the magnetic sheet on the bottom surface of the pressure plate in the mold contacts the silicone pad in the groove and adheres to the inner annular adsorption magnetic plate, forming a magnetic fixation. This design facilitates the assembly and disassembly of the battery box fixing mold. After the initial fixation is completed, the vacuum pump is started by controlling the start of the vacuum pump and the first gas path control valve is opened. At this time, the air in the first vacuum silicone suction cup is extracted, the pressure is reduced, and the external atmospheric pressure is used to press the battery box to be tested against the first vacuum silicone suction cup, thereby achieving the adsorption and fixation of the battery box to be tested. After the second gas path control valve is opened, the air in the second vacuum silicone suction cup is extracted, and the conveyor seat is pressed against the second vacuum silicone suction cup, which can simultaneously fix the conveyor seat and prevent displacement.

[0017] (2) The test scheme of the present invention involves synchronously starting the DC servo motors on both sides, driving the synchronous gears on the corresponding sides to rotate. Under the action of the rack, the conveyor seat and the linkage adsorption structure at the bottom move synchronously. When the contact block in the linkage adsorption structure contacts the elastic touch switch at the first position, the indicator light shows that the conveyor seat has reached the initial test position. Then, the impact plate is lifted to a suitable height using the winch assembly and then lowered to allow the impact component to perform an impact test on the battery box under test at the first position. After that, the conveyor seat and the linkage adsorption structure continue to move synchronously until the contact block contacts the elastic touch switch at the second position, and the indicator light shows that the conveyor seat has reached the second test position. This process is repeated to test three sets of data and analyze them. The above design effectively avoids the shaking of the battery box under test and the left and right displacement of the bottom of the conveyor seat, significantly improving the accuracy of the test results. At the same time, it allows for more flexible positioning of the conveyor seat and is easy to operate. After the test is completed, the above operation is repeated to move the conveyor seat back to the initial position. Activate a pair of miniature lifting cylinders inside the delivery seat to extend the rod and lift the mounting plate. Under the action of the vacuum silicone suction cup, the battery box to be tested is ejected from the battery box fixing mold for easy removal, so that the next battery box to be tested can be placed and fixed.

[0018] (3) The testing scheme of this invention involves installing limiting frames inside the four corner limiting brackets. Then, the adjustable partition is manually slid to adjust its position, dividing the internal space of the limiting frame in two, and the battery box to be tested is placed inside the limiting frame. The operation of starting and controlling the vacuum pump is repeated to fix the battery box to be tested and the transport seat until the test of the battery box is completed. After the test is completed, the corresponding battery box to be tested is removed. This design can meet the placement, fixing, and testing requirements of different types of battery boxes, is flexibly adjustable, significantly improves applicability, reduces testing costs, and thus improves testing efficiency.

[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] like Figures 1 to 8 As shown, a mechanical performance testing device for a new energy battery box includes: The test stand 5 and the frame, the frame including a pair of columns 12 fixed on the test stand 5 and a side frame 13; The impact plate 4 is movably mounted on a pair of columns 12. A set of impact members 41 is fixedly installed on the bottom surface of the impact plate 4 by fixing bolts. It should be noted that the impact members 41 can be cylindrical, spherical, square or other irregular shapes. The installation is selected according to the requirements during testing. In this embodiment, a cylindrical shape is used as an example. The winch assembly is mounted on the frame 13 and is used to lift the impact plate 4. It should be noted that the winch assembly includes a drum, rope, pulley block and motor. The rope is connected to the impact plate 4, which is existing technology and its working principle has been disclosed. This embodiment will not go into detail.

[0023] It also includes: a conveyor table 1, which is fixedly embedded in the test bench 5, a conveyor seat 2 that is slidably arranged inside the port of the conveyor table 1, and a battery box fixing mold 3 that is provided on the conveyor seat 2 for limiting the placement of the battery box. The battery box fixing mold 3 includes a pressure plate 32, corner limiting brackets 31 located at the four corners of the pressure plate 32, a limiting frame 33 fixed to the inside of the four corner limiting brackets 31, and an adjustable plate structure located on the limiting frame 33. The adjustable plate structure is used to adapt and fix battery boxes of different specifications. The adjustable plate structure includes an adjustable partition 34 disposed inside the limiting frame 33. Adjustable grooves 301 are symmetrically provided on both sides of the limiting frame 33. Each adjustable groove 301 contains a movable locking member 35, which consists of a stud 351 and a fastening sleeve 352 threaded onto the stud 351. One end of each stud 351 is fixedly connected to both sides of the adjustable partition 34. The limiting frame 33 is installed inside the four corner limiting brackets 31. The adjustable partition 34 is then manually slid to divide the internal space of the limiting frame 33 in two, and the battery box to be tested is placed inside the limiting frame 33. The operation of starting and controlling the vacuum pump 65 is repeated to fix the battery box to be tested and the transport seat 2 until the test of the battery box is completed. After the test, the corresponding battery box to be tested is removed. This design can meet the placement, fixing, and testing needs of different types of battery boxes, is flexibly adjustable, significantly improves applicability, reduces testing costs, and thus improves testing efficiency.

[0024] In this embodiment, to facilitate the assembly and disassembly of the battery box fixing mold 3, the surface of the conveyor seat 2 is provided with an installation groove 201. A silicone pad 24 with an annular magnetic adsorption plate 241 is embedded in the groove. A magnetic sheet 202 corresponding to the annular magnetic adsorption plate 241 is located at the bottom edge of the pressure plate 32. The two cooperate to form a magnetic fixing structure. When the entire mold along with the battery box is placed into the installation groove 201, the magnetic sheet 202 on the bottom surface of the pressure plate 32 in the mold contacts the silicone pad 24 in the groove and adheres to the annular magnetic adsorption plate 241 inside. The two cooperate to form a magnetic fixing structure. This design facilitates the assembly and disassembly of the battery box fixing mold 3. It also includes: a conveying and positioning mechanism for linear conveying of the conveyor seat 2; The conveying and positioning mechanism includes a rack 21 that is fixedly connected to both sides of the conveying seat 2 and a pair of DC servo motors 22 that are fixedly connected to the test bench 5 on both sides of the conveying table 1. The main shaft of each DC servo motor 22 is fixedly connected to a synchronous gear 23. Each synchronous gear 23 and each rack 21 are meshed to achieve precise linear movement of the conveying seat 2. To simulate the impact of the battery box, a buffer spring 11 is fitted on each column 12. The bottom surface of the buffer spring 11 is fixedly installed on the test platform 5. The buffer spring 11 and the silicone pad 24 form a buffer device, which can be used to simulate the deformation and energy absorption effect of the equipment shell. It also includes: a vacuum adsorption lifting mechanism 6, used for adsorption, fixing and lifting of the battery box fixing mold 3, and a through opening 203 in the middle of the silicone pad 24 for the vacuum adsorption lifting mechanism 6 to pass through. The vacuum adsorption lifting mechanism 6 includes a pair of miniature lifting cylinders 61 fixedly connected to the conveyor seat 2, a mounting plate 62 fixedly connected to the top surface of the rod of the miniature lifting cylinders 61, vacuum silicone suction cups 63 fixedly embedded at the four corners of the mounting plate 62, an air path control valve 64 fixedly connected to the bottom surface of each vacuum silicone suction cup 63, and a vacuum pump 65 fixedly connected to the side of the conveyor table 1. By controlling the start of the vacuum pump 65, the air path control valve 64 is opened. At this time, the air in the vacuum silicone suction cup 63 is extracted and the pressure is reduced. The external atmospheric pressure is used to press the battery box to be tested against the vacuum silicone suction cup 63 to achieve adsorption and fixation of the battery box to be tested and avoid displacement. The vacuum adsorption lifting mechanism 6 also includes a linkage adsorption structure 66. A groove 101 is provided downward in the middle of the port of the conveyor table 1. The linkage adsorption structure 66 includes a slide seat 661 slidably disposed in the groove 101, a T-shaped support plate 662 fixedly connected to the top surface of the slide seat 661, a pair of vacuum silicone suction cups 663 fixedly embedded in the T-shaped support plate 662, and a gas path control valve 664 fixedly connected to the bottom of each vacuum silicone suction cup 663. The air pipeline of the vacuum pump 65 is connected to the gas path control valve 64 and the gas path control valve 664. When the gas path control valve 664 is opened, the air in the vacuum silicone suction cup 663 is extracted, pressing the conveyor seat 2 against the vacuum silicone suction cup 663, thereby synchronously fixing the conveyor seat 2 and preventing displacement.

[0025] In this embodiment, there is also a preferred implementation. The conveying and positioning mechanism further includes a mounting rod 67 fixedly connected to the inner wall of one side of the port of the trench 101. The height of the mounting rod 67 is lower than the height of the groove opening of the trench 101. A set of elastic touch switches 68 are fixedly installed on the mounting rod 67. A contact block 69 is fixedly connected to the T-shaped support plate 662 on the side facing the mounting rod 67. The elastic touch switches 68 are connected to an indicator light 610, which is fixedly installed on the test bench 5. When all the elastic touch switches 68 are triggered in sequence, the indicator light 610 indicates that the conveyor seat 2 has arrived at the test station.

[0026] In this embodiment, there is also a preferred implementation scheme, in which each corner limiting seat 31 is L-shaped and integrally formed with the pressure plate 32. A limiting frame 33 is fixedly installed on the inner side of the four corner limiting seats 31. The four corners of the limiting frame 33 are fixedly connected to each corner limiting seat 31 by fixing bolts for the assembly and disassembly of the limiting frame 33.

[0027] In this embodiment, it should also be noted that the actual dimensions of each component in the application document are selected and installed according to the actual needs on site. Furthermore, it should be noted that this application document only addresses the shortcomings of existing battery box mechanical performance testing equipment, such as inflexible and inaccurate conveying and positioning, unstable fixing, and insufficient adaptability and versatility; it does not involve other aspects. Improvements are made by adopting vacuum adsorption and adjustable fixing methods to solve the problems of the prior art.

[0028] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: In practical use, the present invention tests the battery box in two scenarios: integrated battery box and separate battery box.

[0029] a. Integrated battery box test; To test an integrated battery box, first select a suitable battery box fixing mold 3. Place the battery box to be tested on the mold, ensuring its four corners engage with the four corner retaining brackets 31. Then, place the entire mold along with the battery box into the mounting groove 201. At this point, the magnetic sheet 202 on the bottom surface of the pressure plate 32 in the mold contacts the silicone pad 24 in the groove and adheres to its inner annular magnetic adsorption plate 241, forming a magnetic fixation. This design facilitates the assembly and disassembly of the battery box fixing mold 3. After initial fixation, start the vacuum pump 65 and open the first air control valve 64. At this time, the air in the first vacuum silicone suction cup 63 is extracted, reducing the pressure. Using external atmospheric pressure, the battery box to be tested is pressed against the first vacuum silicone suction cup 63, achieving adsorption and fixation. After opening the second air control valve 664, the air in the second vacuum silicone suction cup 663 is extracted, pressing the delivery seat 2 against the second vacuum silicone suction cup 663.

[0030] Subsequently, the DC servo motors 22 on both sides are started synchronously, driving the corresponding synchronous gears 23 to rotate. Under the action of the rack 21, the conveyor seat 2 and the bottom linkage adsorption structure 66 move synchronously. When the contact block 69 in the linkage adsorption structure 66 contacts the elastic touch switch 68 at the first position, the indicator light 610 shows that the conveyor seat 2 has reached the initial test position. Next, the impact plate 4 is lifted to a suitable height using a winch assembly and then lowered, so that the impact component 41 performs an impact test on the battery box under test at the first position. After that, the conveyor seat 2 and the linkage adsorption structure 66 continue to move synchronously until the contact block 69 contacts the elastic touch switch 68 at the second position, and the indicator light 610 shows that the conveyor seat 2 has reached the second test position. This process is repeated to test three sets of data and analyze them. The above design effectively avoids the shaking of the battery box under test and the left and right displacement of the bottom of the conveyor seat 2, significantly improving the accuracy of the test results, while also allowing for more flexible positioning of the conveyor seat 2 and convenient operation.

[0031] After the test is completed, repeat the above operation to move the conveyor seat 2 to the initial position. Activate the pair of miniature lifting cylinders 61 inside the conveyor seat 2 to extend the rods and lift the mounting plate 62. Under the action of the vacuum silicone suction cup 63, the battery box to be tested is pushed out from the battery box fixing mold 3 for easy removal, so that the next battery box to be tested can be placed and fixed.

[0032] b. Test of separate battery box To test a split-type battery box (taking two as an example), first install the limiting frame 33 inside the four corner limiting brackets 31. Then, manually slide the adjustable partition 34 to adjust its position, dividing the internal space of the limiting frame 33 in two, and place the battery box to be tested into the limiting frame 33. Repeat the operation of starting and controlling the vacuum pump 65 to fix the battery box to be tested and the transport seat 2 until the test of the battery box is completed. After the test is completed, remove the corresponding battery box to be tested. This design can meet the placement, fixing and testing needs of different types of battery boxes, is flexible and adjustable, significantly improves applicability, reduces testing costs, and thus improves testing efficiency.

[0033] The above-disclosed embodiments are only a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
