[0020] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, the conveying equipment 2 installed inside the installation pipe 1 is used to convey the automobile battery pack 7. The blocking structure 5 is arranged in the forward direction of the automobile battery pack 7 to block the automobile battery pack 7. A pressure sensor 55 is fixedly embedded at the bottom of the blocking plate 54. When the automobile battery pack 7 contacts the pressure sensor 55, the pressure value detected by the pressure sensor 55 changes. After the human-computer interaction device receives the feedback from the pressure sensor 55, it controls the conveying equipment 2 to suspend work and preliminarily locates the automobile battery pack 7.

By controlling the operation of the pneumatic cylinder 56, the relative position between the microcomputer 6 and the car battery pack 7 intercepted by the baffle plate 54 can be controlled. The end of the transmission shaft three 52 away from the forward and reverse motor three 51 is rotatably connected to the mounting pipe 1, and the outer side of the transmission shaft three 52 is provided with a brake three 53, which is fixedly connected to the mounting pipe 1. When the forward and reverse motor three 51 finishes working, the brake three 53 works to limit the transmission shaft three 52, ensuring that the baffle plate 54 stably performs its function of intercepting and positioning the car battery pack 7.

[0023] Specifically, such as Figure 1 、 Figure 2 、 Figure 5 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11As shown, the mounting shell 41 is fixedly installed on the outside of the mounting pipe 1, and the movable chamber 42 set on one side of the mounting shell 41 is opened on the outside of the mounting pipe 1. A hydraulic cylinder 2 414 and two telescopic rods 2 415 are fixedly installed at the bottom of the inner cavity of the mounting shell 41. The piston ends of the hydraulic cylinder 2 414 and the two telescopic rods 2 415 are fixedly connected to the L-shaped frame 416. By controlling the operation of the hydraulic cylinder 2 414, the L-shaped frame 416 can be pushed to move up and down. Under the action of the two telescopic rods 2 415, the L-shaped frame 416 can only move up and down.

[0024] A stress simulation component is installed on the L-shaped frame 416. In the stress simulation component, a hydraulic cylinder 3 426 is fixedly installed on the L-shaped frame 416. The piston end of the hydraulic cylinder 3 426 is fixedly installed with a mounting frame 423. The piston ends of the two telescopic rods 3 425 fixedly installed on the L-shaped frame 416 are fixedly connected to the mounting frame 423. Under the action of the telescopic rod 3 425 and the hydraulic cylinder 3 426, the mounting frame 423 can only move in the horizontal direction. By controlling the hydraulic cylinder 3 426 to work and extend, the mounting frame 423 and the multiple vacuum suction cups 422 fixedly installed on the mounting frame 423 can be pushed through the movable cavity 42 to move into the interior of the mounting pipe 1, so that the vacuum suction cups 422 are in contact with the vehicle battery pack 7; and an air guide frame 420 is fixedly connected between the multiple vacuum suction cups 422. An air pressure sensor 421 and a solenoid valve are fixedly installed on the outside of the air guide frame 420. Three 433 and telescopic tube 419, one end of the telescopic tube 419 is fixedly connected to the air inlet end of the vacuum pump 417 fixedly provided on the L-shaped frame 416, and the air outlet end of the vacuum pump 417 is fixedly connected to the solenoid valve 1 418, and the solenoid valve 1 418 is in a normally open state. When the vacuum suction cup 422 is tightly attached to the outer shell of the automobile battery pack 7, the vacuum pump 417 is controlled to work. Under the action of the telescopic tube 419 and the air guide frame 420, the vacuum pump 417 draws air from the inside of the multiple vacuum suction cups 422, so that a negative pressure is generated between the vacuum suction cup 422 and the automobile battery pack 7. The air pressure sensor 421 detects the air pressure value inside the air guide frame 420. When the air pressure value feedback from the air guide frame 420 reaches a preset value, the solenoid valve 1 418 is controlled to close, and a negative pressure state is maintained between the vacuum suction cup 422 and the automobile battery pack 7, and the vacuum suction cup 422 is fixed to the automobile battery pack 7.

[0025] A plurality of guide frames 424 are fixedly connected between the air guide frame 420 and the mounting frame 423. The guide frames 424 are slidably inserted into the L-shaped frame 416. The air guide frame 420 and the mounting frame 423 move in an integrated manner. The setting of the retractable telescopic tube 419 ensures that the air guide frame 420 will not be disconnected from the vacuum pump 417 when moving within a certain range. The force of the up and down movement of the L-shaped frame 416 is synchronously applied to the air guide frame 420 and the mounting frame 423 through the plurality of guide frames 424, and the plurality of vacuum suction cups 422 move up and down.

[0026] A water heater 427 is fixedly connected to the top of the air guide frame 420, and the normally open water outlet end of the water heater 427 is fixedly connected to a liquid pump 428, and the water outlet end of the liquid pump 428 is fixedly connected to an electromagnetic valve 2 432, and the electromagnetic valve 2 432 is in a normally open state. A water guide frame 429 fixedly connected to one side of the electromagnetic valve 2 432 is fixedly connected to a plurality of diversion elbows 430, and one end of the diversion elbow 430 is fixedly connected to the bottom of the inner cavity of the adjacent vacuum suction cup 422. A hydraulic expansion member 431 is provided on one side of the diversion elbow 430, and the hydraulic expansion member 431 is fixedly installed inside the adjacent vacuum suction cup 422. Multiple hydraulic expansion members 431, multiple diversion elbows 430, a water guide frame 429, the liquid pump 428 and the water heater 427 form a smooth water storage system, and the water heater 427 heats the liquid in the water storage system when it works.

[0027] In summary, by operating the stress simulation component, the front and rear positions of the vacuum suction cup 422 , the upper and lower positions of the plurality of vacuum suction cups 422 , and the internal air pressure of the vacuum suction cup 422 can be controlled.

[0028] Specifically, such as Figure 2 、 Figure 5 、 Figure 6 and Figure 7 As shown, the motion platform 43, the friction plate 45 and the forward and reverse motor 2 410 in the jacking assembly are all arranged inside the mounting housing 41. Two guide frames 2 48 are slidably penetrated at the bottom of the motion platform 43. The guide frames 2 48 are fixedly connected to the mounting housing 41 so that the motion platform 43 can only move according to a preset trajectory. A hydraulic cylinder 1 46 and two telescopic rods 1 47 are fixedly penetrated on the motion platform 43. The piston ends of the hydraulic cylinder 1 46 and the telescopic rod 1 47 are fixedly connected to the friction plate 45 to control the operation of the hydraulic cylinder 1 46 to push the friction plate 45 upward. A rack 2 48 is fixedly embedded at the bottom of the motion platform 43. 9. The output end of the forward and reverse motor 2 410 fixedly installed on the installation pipe 1 is fixedly connected to the transmission shaft 2 413. The outer side of the transmission shaft 2 413 is provided with a gear 2 412 and a brake 2 411. The gear 2 412 is fixedly sleeved on the outer side of the transmission shaft 2 413 and meshes with the rack 2 49 to control the forward and reverse rotation of the forward and reverse motor 2 410. Under the action of the transmission shaft 2 413, the gear 2 412 and the rack 2 49, the moving platform 43 enters the interior of the installation pipe 1 or returns to the interior of the installation shell 41 through the movable cavity 42 to control the operation of the jacking assembly, and the moving platform 43 and the friction plate 45 move.

[0029] And the brake 2 411 is fixedly connected to the installation pipe 1. After the forward and reverse motor 2 410 finishes working, the brake 2 411 is controlled to work to limit the transmission shaft 2 413, so that the gear 2 412 cannot rotate and the position of the moving platform 43 cannot move.

[0030] Specifically, such as Figure 1 、 Figure 2 and Figure 4 As shown, a door control structure 3 is installed on the top of the inner cavity of the installation pipe 1. The forward and reverse motor 31 in the door control structure 3 is fixedly installed inside the installation pipe 1. A gear 33 is fixedly sleeved on the outer side of a transmission shaft 32 fixedly connected to the output end of the forward and reverse motor 31. A rack 35 engaged with the gear 33 is fixedly connected to the door body 36. Because two guide frames 37 passing through the door body 36 are fixedly connected to the inner wall of the installation pipe 1, the door body 36 is slidably installed with the installation pipe 1, so the forward and reverse control is controlled. When the motor 31 rotates forward or reverse, under the action of the transmission shaft 32, gear 33 and rack 35, the door body 36 moves left to open the door cavity on the installation pipe 1 or moves right to seal the installation pipe 1, and a fixed plate 38 is fixedly connected between the brake 34 provided on the outer side of the transmission shaft 32 and the installation pipe 1, which controls the operation of the brake 34 to brake and limit the transmission shaft 32, the gear 33 is limited, and the rack 35 is limited, thereby ensuring the stability of the position control of the door body 36.

[0031] By controlling the door control structure 3 to work, the upper door cavity of the installation pipe 1 can be exposed and communicated with the outside.

[0032] In this application, a battery pack sinking installation auxiliary device is composed of a conveying equipment 2, an installation pipe 1, a door control structure 3, a material blocking structure 5, two installation auxiliary structures 4 and other structures. The battery pack sinking installation auxiliary device is connected to a human-computer interaction device to realize automated work, which is an existing technology application and will not be repeated here.

[0033] The specific working principle of the battery pack sinking installation auxiliary device is as follows: The battery pack sinking installation auxiliary device is installed in advance, so that one end of the installation pipe 1 is set in the battery pack storage workshop, most of the installation pipe 1 is buried on the ground of the vehicle assembly workshop, the top door cavity of the installation pipe 1 is aligned with the battery pack installation cavity in the middle of the vehicle chassis, and the other end of the installation pipe 1 is set in the battery recovery workshop.

[0034] In the battery pack storage workshop, the staff places the automobile battery pack 7 on the top of the conveying device 2, and the conveying device 2 conveys the automobile battery pack 7 to move toward the blocking structure 5. After the pressure sensor 55 in the blocking structure 5 is pressed against the automobile battery pack 7, the human-computer interaction device controls the conveying device 2 to suspend work after receiving the feedback from the pressure sensor 55, completing the preliminary positioning of the automobile battery pack 7; then the human-computer interaction device controls the two installation auxiliary structures 4 to work, and the two stress simulation components in the two installation auxiliary structures 4 work, so that multiple vacuum suction cups 422 move from both sides of the automobile battery pack 7 to the automobile battery pack 7, and multiple vacuum suction cups 42 2 respectively against both sides of the vehicle battery pack 7, and finally, under the action of the baffle plate 54 and the two stress simulation components, the vehicle battery pack 7 is aligned with the top door cavity of the installation pipe 1, and the vehicle battery pack 7 is aligned with the battery pack installation cavity in the middle of the vehicle chassis, completing the positioning of the vehicle battery pack 7, and the battery pack sinking installation auxiliary device is installed underground, so that the transportation and positioning work of the vehicle battery pack 7 is all located below the workshop floor, and the alignment work of the vehicle battery pack 7 with the battery pack installation cavity in the middle of the vehicle chassis can be completed quickly and simply, reducing the space required for the sunken installation of the vehicle battery pack 7 and reducing the cost investment required for the sunken installation of the vehicle battery pack 7.

[0035] Subsequently, the two stress simulation components are controlled to work, and negative pressure is generated inside the multiple vacuum suction cups 422 to adsorb and fix the car battery pack 7. At this time, the relative position between the vacuum suction cup 422 and the car battery pack 7 does not change. At this time, the side wall position of the vacuum suction cup 422 applies a thrust to a local position of the car battery pack 7 shell, and the negative pressure inside the vacuum suction cup 422 applies a pulling force to a local position of the car battery pack 7 shell, and the car battery pack 7 shell at the position of the vacuum suction cup 422 is torn; immediately afterwards, the hydraulic cylinder 2 414 in the two installation auxiliary structures 4 is controlled to work, the two L-shaped frames 416 move up, the two stress simulation components move up, and the car battery pack 7 moves up. When the USB interface on the car battery pack 7 moves to the side of the USB connector 61, the hydraulic cylinder 2 414 stops moving, and the blocking structure 5 is controlled to work to push the microcomputer 6 to move toward the car battery pack 7, so that the USB connector 61 is inserted into the USB interface of the car battery pack 7, so that the microcomputer 6 tests the car battery system in the battery firmware in the car battery pack 7. For details of the test, please see below.

[0036] While waiting for the car frame to be assembled, the car battery system is fuzzy tested. Under the action of the installation auxiliary structure 4, the outer shell of the car battery pack 7 is torn at multiple locations. While testing the safety of the car battery pack 7, the state of the battery shell being hit by external force is simulated. The air pressure sensor 421 detects the air pressure value inside the air guide frame 420 and feeds it back to the microcomputer 6; due to the upward movement of the L-shaped frame 416, the camera 44 fixedly installed inside the installation shell 41 can capture the bottom of the car battery pack 7. In order to determine whether the rest of the bottom of the car battery pack 7 is bulging due to the suspension and local squeezing of the car battery pack 7, the human-computer interaction device determines. After a period of time, the liquid extraction pump 428 is controlled to extract the high-temperature liquid inside the water heater 427. Under the action of the water guide frame 429 and multiple diversion bends 430, the liquid extraction pump 428 pushes the high-temperature liquid into the multiple hydraulic expansion parts 431. The hydraulic pressure inside the hydraulic expansion parts 431 increases, and the multiple hydraulic expansion parts 431 expand and contact the outer wall of the automobile battery pack 7, causing the outer wall of the automobile battery pack 7 to be locally heated. Only some of the vacuum suction cups 422 have hydraulic expansion parts 431, and the automobile battery pack 7 is stably clamped and fixed. The working condition of the automobile battery system in the battery firmware inside the automobile battery pack 7 under the local high temperature outside the automobile battery pack 7 is tested.

[0037] After a period of time, the four lifting components in the two installation auxiliary structures 4 are controlled to work, so that the moving platform 43 and the friction plate 45 enter the installation pipe 1, and the friction plate 45 moves to the bottom of the automobile battery pack 7. The hydraulic cylinder 1 46 at the bottom of the friction plate 45 is controlled to work, and the friction plate 45 rises to support the bottom of the automobile battery pack 7. The four friction plates 45 support the four corners of the bottom of the automobile battery pack 7. Then the solenoid valve 3 433 is controlled to work and open, the internal pressure of the air guide frame 420 is relieved, the internal pressure of the vacuum suction cup 422 is relieved, and the hydraulic cylinder 2 414 and the stress simulation component are controlled to reset. At this time, the L-shaped frame 416 is located at the bottom of the camera 44. The camera 44 can shoot the outer wall of the automobile battery pack 7 after stress is applied by the stress simulation component, and provide data for the human-computer interaction device to judge whether the automobile battery pack 7 is qualified. The human-computer interaction device judges whether the automobile battery pack 7 is qualified based on the image captured by the camera 44 and the test results of the microcomputer 6.

[0038] When the automobile battery pack 7 is qualified and the automobile frame assembly progress meets the requirements for the installation of the automobile battery pack 7, the door control structure 3 is controlled to work so that the upper door cavity of the installation pipe 1 is exposed and connected to the outside world, and the jacking assembly is controlled to work to push the automobile battery pack 7 into the battery pack installation cavity in the middle of the vehicle chassis. After the automobile battery pack 7 is fixed to the vehicle chassis, the jacking assembly is reset and the door control structure 3 is operated to close the upper door cavity of the installation pipe 1.

[0039] When the car battery pack 7 is unqualified, the hydraulic cylinder 46 drives the friction plate 45 to move downward, and then the jacking assembly is reset. The bottom of the car battery pack 7 loses support and falls to the top of the conveying equipment 2. The blocking structure 5 releases the limit, and the car battery pack 7 can continue to be conveyed by the conveying equipment 2. The unqualified car battery packs 7 are centrally processed. After the blocking structure 5 is restored to its original state, the next car battery pack 7 is conveyed by the conveying equipment 2, and the new car battery pack 7 is tested. The qualified car battery pack 7 is installed on the vehicle chassis.

[0040] In summary, the present application sets two installation auxiliary structures 4 on both sides of the conveying equipment 2. During the process of clamping and transporting the automobile battery pack 7 with the stress simulation component in the installation auxiliary structure 4, the camera 44 cooperates with the stress simulation component and the jacking component to detect whether the external hardware of the automobile battery pack 7 is qualified. The internal air pressure value of the air guide frame 420 detected by the air pressure sensor 421, the internal hydraulic value when the hydraulic cylinder 426 applies thrust to the vacuum suction cup 422, and the internal liquid temperature value of the water heater 427 are all fed back to the microcomputer 6 as the actual parameters of the microcomputer 6 to test the automobile battery system. The time for the automobile battery pack 7 to be installed after positioning is used to achieve the purpose of synchronous testing of the easily damaged external hardware of the automobile battery pack 7 and the internal automobile battery system of the automobile battery pack 7.

[0041] In addition, such as Figure 12 As shown, the principle of the automobile battery system test in the battery firmware of the automobile battery pack 7 by the microcomputer 6 is as follows; the microcomputer 6 internally stores an automobile battery firmware fuzzy testing system composed of a data reading module 62, a fuzzy testing model 63, an abnormal data storage module 64, a digital-to-analog conversion module 66, an installation vulnerability locking module 67 and a report generation module 68. The output ends of the data reading module 62, the abnormal data storage module 64 and the digital-to-analog conversion module 66 are all communicated with the fuzzy testing model 63, the output end of the fuzzy testing model 63 is communicated with the installation vulnerability locking module 67, and the output end of the installation vulnerability locking module 67 is communicated with the report generation module 68; and the output end of the wireless signal transceiver 65 fixedly installed on the microcomputer 6 is communicated with the digital-to-analog conversion module 66.

[0042] When the USB connector 61 is plugged into the USB interface on the car battery pack 7, the data reading module 62 reads the car battery system stored in the battery firmware in the car battery pack 7, the fuzzy test model 63 copies the car battery system, and the random data stored in the abnormal data storage module 64 that needs to be processed by the car battery system during car operation is transmitted to the fuzzy test model 63. The fuzzy test model 63 performs fuzzy testing on the car battery system with the random data as parameters, and the vulnerability locking module 67 is installed to lock the security vulnerabilities in the fuzzy test of the car battery system; when the number of random data transmitted in the abnormal data storage module 64 reaches a preset number, the air pressure value inside the air guide 420 detected by the air pressure sensor 421, the hydraulic value when the hydraulic cylinder 426 applies thrust to the vacuum suction cup 422, and the liquid temperature value inside the water heater 427 are all fed back to the microcomputer 6 through the wireless communication module, and the wireless signal transceiver 65 in the microcomputer 6 receives the air pressure value, thrust value and temperature value, and the air pressure value, thrust value and temperature value are counted. The model conversion module 66 converts the data into test data and then transmits it to the fuzzy test model 63. The fuzzy test model 63 uses the test data as parameters to test the automobile battery system and generates the response data that the automobile battery system should have when the actual situation occurs. The data reading module 62 collects the actual response data of the automobile battery system inside the automobile battery pack 7 in real time. The installation vulnerability locking module 67 compares the actual response data with the expected response data to determine whether there is a security vulnerability in the actual operation of the automobile battery system. When there is no security vulnerability in the automobile battery system, the automobile battery system passes the test. When there is a security vulnerability in the automobile battery system, the automobile battery system fails the test. The judgment result of the installation vulnerability locking module 67 is edited by the report generation module 68 and sent to the human-computer interaction device through the wireless signal transceiver 65. The human-computer interaction device determines whether the vulnerable hardware outside the automobile battery pack 7 and the automobile battery system inside the automobile battery pack 7 are qualified based on the test results of the microcomputer 6 and the shooting results of the camera 44. When both are qualified, the automobile battery pack 7 is qualified.
