[0029] 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.

[0030] Example 1: Please refer to Figures 1-5 In existing teaching and training models for power battery packs, the power battery pack is stored inside the teaching and training device, which makes it inconvenient to protect the power battery pack for safety. In order to solve this technical problem, this embodiment discloses the following technical content;

[0031] A teaching and training model of a power battery pack with safety protection is provided. The front outer end of the storage box 1 is fixedly connected to a first magnetic plate 2, and the middle of the bottom front end of the storage box 1 is fixedly connected to a latch 3. The top of the storage box 1 is rotatably connected to an L-shaped cover plate 4. The lower outer end of the L-shaped cover plate 4 is fixedly connected to a second magnetic plate 5. The first magnetic plate 2 and the second magnetic plate 5 are respectively fixedly connected to the slots opened on the storage box 1 and the L-shaped cover plate 4, and the first magnetic plate 2 and the second magnetic plate 5 are magnetically connected. The middle of the bottom front end of the L-shaped cover plate 4 is provided with a through hole 6, and the latch 3 is connected through the through hole 6. The middle of the top end of the storage box 1 is rotatably connected to a handle 7, and the middle of the upper ends of the left and right sides of the storage box 1 are fixedly connected to limit plates 8.

[0032] A base plate 9 is fixedly connected to the inner center of the storage box 1, and partitions 10 are fixedly connected to the lower surface of the base plate 9 at equal intervals on both the left and right ends. Hollow manual telescopic rods 11 and springs 12 are fixedly connected to the front, middle and rear ends of the inner left side of the storage box 1 and the right side of the partitions 10. The right side of the hollow manual telescopic rod 11 is fixedly connected to the side plate 13, and the lower surface of the side plate 13 is in contact with the inner lower surface of the storage box 1. A protective pad 14 is fixedly connected to the right side of the side plate 13.

[0033] The storage box 1 has a movable mechanism at the bottom front of its interior. The movable mechanism is composed of a storage slot 15, a baffle 16, a rotating plate 17, and a fixing bolt 18. The storage slot 15 is located at the bottom front of the storage box 1. The baffle 16 is rotatably connected inside the storage slot 15. The upper front end of the baffle 16 is rotatably connected to the rotating plate 17 inside the storage box 1. The rear side of the rotating plate 17 fits against the front side of the baffle 16. The left and right ends of the bottom front of the storage box 1 are rotatably connected to the rotating plate 17. The outer end of the rotating plate 17 is threaded with a fixing bolt 18.

[0034] The handle 7 can rotate at the top of the storage box 1. Since the upper surface of the limiting plate 8 is in contact with the inner outer side of the handle 7, the limiting plate 8 restricts the handle 7. When the power battery pack teaching and training model is in training, when the L-shaped cover 4 is closed on the storage box 1, the latch 3 at the bottom front side of the storage box 1 passes through the through hole 6 at the bottom front side of the L-shaped cover 4. The latch 3 can be locked by passing through the front end of the latch 3 to prevent the L-shaped cover 4 from falling off the storage box 1. When in use, the latch fixed on the latch 3 is removed, and the bottom front side of the L-shaped cover 4 is lifted up so that the L-shaped cover 4 can be rotated open. At this time, the first magnetic plate 2 on the storage box 1 and the second magnetic plate 5 on the L-shaped cover 4 are separated. The first magnetic plate 2 and the second magnetic plate 5 magnetically connect the storage box 1 and the L-shaped cover 4 together, so that the L-shaped cover 4 and the storage box 1 can be tightly connected together.

[0035] After opening the power battery pack teaching and training model, the storage box 1, the base plate 9, and the partition 10 divide the space for placing the power battery pack. The left side of the power battery pack is in contact with the side plate 13 and the protective pad 14, and the right side of the power battery pack is in contact with the right side of the storage box 1 and the left side of the partition 10. The left side of the side plate 13 is fixedly connected to one end of the hollow manual telescopic rod 11. A spring 12 is provided on the inner side of the hollow manual telescopic rod 11. When the spring 12 is subjected to force, it deforms, causing the hollow manual telescopic rod 11 to extend and retract, moving the side plate 13 laterally to clamp the power battery pack and the partition 10. The protective pad 14 is in contact with the power battery pack, which can protect the power battery pack.

[0036] A movable mechanism is provided at the bottom front of the power battery pack inside the storage box 1. The movable mechanism blocks the front of the power battery pack to prevent it from sliding out of the storage box 1, the bottom plate 9, and the partition 10. The baffle 16 is rotatably connected to the storage slot 15. When the baffle 16 is vertical, the rear side of the baffle 16 is in contact with the rear side of the storage slot 15. When the baffle 16 is vertical, rotating the rotating plate 17 causes the rear side of the rotating plate 17 to contact the front side of the baffle 16. With the surfaces aligned, tighten the stabilizing bolts 18 on the outer end of the rotating plate 17 to fix the rotating plate 17 inside the storage box 1, so that the baffle 16 protects the front side of the power battery pack. When the power battery pack needs to be removed, loosen the stabilizing bolts 18, rotate the bottom end of the rotating plate 17 upward, and rotate the baffle 16 forward and place it. When the baffle 16 is placed, the upper surface of the baffle 16 is on the same plane as the inner bottom surface of the storage box 1, so that the power battery pack can be removed from the storage space.

[0037] Example 2: Existing teaching and training models for power battery packs require placing the power battery pack on a teaching platform during training, which makes it inconvenient to adjust the height of the platform. Therefore, this example uses the following technical solution: Figures 1-3 and Figure 6 As shown;

[0038] The height adjustment mechanism is composed of a shelf 19, a connecting plate 20, a motor 21, a lead screw 22, and a limiting rod 23. The lower surface of the shelf 19 is fixedly connected to the left and right ends of the connecting plate 20, and the top rear end of the left side of the connecting plate 20 is equipped with a motor 21. The output shaft of the motor 21 is fixedly connected to the lead screw 22. The front and rear ends of the right side and the front end of the left side of the connecting plate 20 are all connected through the limiting rod 23. The lead screw 22 and the limiting rod 23 are installed at the four corners of the upper end of the base plate 9.

[0039] The removed power battery pack is placed on the shelf 19. During practical training, the shelf 19 can be raised to make the training more convenient. When the shelf 19 is raised, the motor 21 is started. The output shaft of the motor 21 drives the lead screw 22 to rotate, so that the shelf 19 and the connecting plate 20, which are threaded to the lead screw 22, can move automatically upward. The front and rear ends on the right side and the front end on the left side of the connecting plate 20 are restricted by the limiting rod 23. The connecting plate 20 is an "L" shaped plate. The horizontal plate at the bottom of the connecting plate 20 is connected to the lead screw 22 and the limiting rod 23. This mechanism can be used to make the shelf 19 for placing the power battery pack automatically rise and fall.
