Description

Technical Field

[0001] This utility model relates to the field of automotive repair teaching technology, specifically to a power battery disassembly training device. Background Technology

[0002] The power battery disassembly training device is an important piece of equipment for teaching, research, and skills training in new energy vehicle-related majors. Its main functions include: helping students and trainees intuitively understand the internal structure of power batteries, master assembly processes and connection methods; training in safe and standardized operating procedures through a simulated real disassembly environment; learning to use professional tools and improving fault analysis and maintenance capabilities; providing a disassembly platform for researchers to analyze the design differences and material characteristics of different types of batteries; supporting the research and development of battery recycling technologies and the verification of new processes; popularizing new energy knowledge among the public and industry practitioners; providing practical scenarios for relevant vocational qualification training to assist in skills assessment; demonstrating safe handling and emergency procedures after battery disposal; strengthening environmental awareness; intuitively showcasing the recycling value of battery materials; and promoting the dissemination of the circular economy concept. Through a combination of theory and practice, it meets the needs of teaching, research, and skills training, providing a safe and standardized training platform for the new energy vehicle industry chain, and contributing to talent cultivation and technological innovation in the industry.

[0003] Most automotive repair schools have training rooms where students are taught through practical experience. Although the new energy vehicle industry has been developing in China for some time, automotive repair schools still mainly use gasoline vehicles as models for teaching. Although some higher automotive repair colleges have established new energy majors, they use simulated batteries for teaching because batteries are expensive and easily damaged by collisions. However, when students disassemble simulated batteries, they cannot use the simulated batteries to determine whether excessive force or collisions have caused battery damage during the disassembly process. Utility Model Content

[0004] The purpose of this invention is to provide a training device for disassembling power batteries to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power battery disassembly training device, including an outer packaging shell, a simulated battery shell inside the outer packaging shell, a detection block inside the simulated battery shell, a pressure shell below the detection block, and a gas tank below the detection block.

[0006] The detection block uses a spiropyran compound, and an observation window is provided on the top of the detection block.

[0007] Preferably, a protective plate is fixedly installed on the inner sidewall of the outer packaging shell, an installation frame is fixedly installed on the outer surface of the protective plate, an installation base is fixedly installed on the outer surface of the installation frame, and the simulated battery shell is fixedly installed on the outer surface of the installation base by bolts.

[0008] Preferably, a sliding column is fixedly installed on the inner bottom wall of the simulated battery casing, a bearing plate is slidably connected to the outer surface of the sliding column, and two springs are sleeved on the outer surface of the sliding column, with one end of each spring fixedly connected to the outer surface of the bearing plate.

[0009] Preferably, the inner side of the support plate has a reserved opening, the gas tank is located at the reserved opening of the support plate and is fixedly installed on the inner bottom wall of the simulated battery shell, and the gas tank is equipped with a pressure gauge and an air injection port.

[0010] Preferably, the outer surface of the bearing plate is fixedly installed on the outer surface of the air pressure shell, four exhaust pipes are fixedly installed at the output end of the air tank, the interior of the air tank is interconnected with the interior of the air pressure shell through the exhaust pipes, and a push shell is slidably connected to the inner wall of the air pressure shell.

[0011] Preferably, a load-bearing plate is fixedly installed on the top surface of the push shell, and two grooves are formed on the inner side of the load-bearing plate. The detection block is detachably connected to the grooves located on the load-bearing plate.

[0012] Preferably, the outer surface of the simulated battery casing is detachably connected to a protective cover, the inner side of the protective cover is fixedly installed on the outer surface of the observation window, and the bottom surface of the protective cover and the bottom surface of the observation window are both in contact with and tightly attached to the outer surface of the detection block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application utilizes the cooperation between a simulated battery casing, outer packaging shell, detection block, gas tank, and pressure shell. During disassembly, the outer packaging shell and simulated battery casing can mimic a battery installed on a new energy electric vehicle chassis. The gas tank can push the detection block above the pressure shell through air pressure. When the battery is impacted or subjected to excessive force, the detection block will be appropriately squeezed. Since the detection block uses spiropyran compounds, when squeezed, the spiro ring structure in the molecule opens under mechanical force, forming a planar cyanine structure, resulting in a change in the absorption spectrum (such as changing from colorless to colored). Thus, the color change of the detection block can be used to determine whether the user has used excessive force during disassembly, thereby solving the problem of not being able to determine whether excessive force or impact has caused battery damage during disassembly using a simulated battery.

[0015] 2. This application utilizes the cooperation between the protective cover, the simulated battery casing, and the observation window. When the detection block changes color, the color of the detection block can be directly seen through the observation window. Thus, when the detection block changes color, the trainee can quickly notice it and determine which part of the disassembly process caused the collision. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figures 1-5As shown, this utility model provides a technical solution for a power battery disassembly training device, including an outer packaging shell 1, a simulated battery shell 2 inside the outer packaging shell, a detection block 3 inside the simulated battery shell 2, a pressure shell 4 below the detection block 3, and a gas tank 5 below the detection block 3. The detection block 3 uses a spiropyran compound, and an observation window 6 is provided above the detection block 3. During the disassembly process, the outer packaging shell 1 and the simulated battery shell 2 can simulate a battery installed on a new energy electric vehicle chassis, and the gas tank 5 can push the pressure shell 4 upwards through air pressure. The detection block 3 will be appropriately squeezed when the battery is bumped or subjected to excessive force. Since the detection block 3 is made of spiropyran compound, the spiro ring structure in the molecule will open under mechanical force when squeezed, forming a planar cyanine structure, which will cause the absorption spectrum to change (such as from colorless to colored). Thus, the color change of the detection block 3 can be used to determine whether the trainee has used too much force during the disassembly process, thereby solving the problem that it is impossible to determine whether the battery has been damaged by excessive force or collision during the disassembly process by simulating the battery.

[0024] A protective plate 7 is fixedly installed on the inner wall of the outer packaging shell 1. An installation frame 8 is fixedly installed on the outer surface of the protective plate 7. An installation seat 9 is fixedly installed on the outer surface of the installation frame 8. The simulated battery shell 2 is fixedly installed on the outer surface of the installation seat 9 by bolts. The protective plate 7 and the installation frame 8 can appropriately protect the simulated battery shell 2 and provide a certain buffering effect. The installation seat 9 can facilitate the installation of the simulated battery shell 2, providing students with a simulated battery installation structure.

[0025] A sliding column 10 is fixedly installed on the inner bottom wall of the simulated battery casing 2. A support plate 11 is slidably connected to the outer surface of the sliding column 10. Two springs 12 are sleeved on the outer surface of the sliding column 10. One end of each spring 12 is fixedly connected to the outer surface of the support plate 11. The support plate 11 can slide up and down on the outer surface of the sliding column 10. The springs 12 are made of high-strength steel and can provide support and load-bearing function for the support plate 11 when the device is stationary. When the simulated battery casing 2 is subjected to a large impact, the support plate 11 will be constrained by inertia and the restoring effect of the springs 12, which will cause the support plate 11 to shake up and down. This will cause the support plate 11 to drive the detection block 3 to hit the bottom surface of the cover 15 on the top of the simulated battery casing 2, thereby causing the detection block 3 to change color.

[0026] The inner side of the support plate 11 has a reserved opening. The gas tank 5 is located at the reserved opening on the support plate 11 and is fixedly installed on the inner bottom wall of the simulated battery shell 2. The gas tank 5 is equipped with a pressure gauge and an air injection port. The reserved opening on the support plate 11 can provide reserved installation space for the gas tank 5, so that the gas tank 5 can be directly installed on the inner bottom surface of the simulated battery shell 2. The air pressure in the gas tank 5 can be controlled by the air injection port and the pressure gauge. By adjusting the air pressure, the air pressure driving force in the air pressure shell 4 can be adjusted, thereby adjusting the squeezing force between the detection block 3 and the cover 15. In this way, the collision sensitivity of different battery models can be simulated by adjusting the squeezing force.

[0027] The outer surface of the bearing plate 11 is fixedly installed on the outer surface of the air pressure shell 4. Four exhaust pipes 16 are fixedly installed at the output end of the air tank 5. The interior of the air tank 5 is connected to the interior of the air pressure shell 4 through the exhaust pipes 16. The inner wall of the air pressure shell 4 is slidably connected to the push shell 13. The air pressure in the air tank 5 can be introduced into the air pressure shell 4 through the exhaust pipes 16, so that the air pressure shell 4 can push the push shell 13 through the air pressure.

[0028] A load-bearing plate 14 is fixedly installed on the top surface of the push shell 13. Two grooves are opened on the inner side of the load-bearing plate 14. The detection block 3 is detachably connected to the groove of the load-bearing plate 14. The push shell 13 can be controlled by the air pressure below to push the bearing plate 11, so that the bearing plate 11 can push the detection block 3 to stick tightly to the bottom surface of the cover 15.

[0029] The outer surface of the simulated battery casing 2 is detachably connected to a cover 15. The inner side of the cover 15 is fixedly installed on the outer surface of the observation window 6. The bottom surface of the cover 15 and the bottom surface of the observation window 6 are in contact with and tightly attached to the outer surface of the detection block 3. When the detection block 3 changes color, the color of the detection block 3 can be directly seen through the observation window 6. Thus, when the detection block 3 changes color, the trainee can quickly notice it and determine which part of the disassembly process caused the collision.
