Description

Technical Field

[0001] This utility model relates to the field of battery cell disassembly technology, and in particular to a battery cell disassembly device. Background Technology

[0002] Aircraft batteries (aviation batteries) are a crucial component of aircraft electrical systems, primarily used for starting auxiliary power units, providing emergency power, and serving as backup power. Their design must meet requirements for high reliability, lightweight construction, and resistance to extreme environments. Aircraft batteries consist of a casing and multiple individual battery cells housed within it. When servicing aircraft batteries, it is necessary to remove these individual cells. The common practice is to first fix tools to the positive and negative terminals of each cell and then forcibly pull them out. This method easily damages the casing of the battery cells, causes poor electrode contact, and may also damage surrounding components, posing safety hazards and resulting in low efficiency. Utility Model Content

Detailed Implementation

[0014] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] like Figure 1-2 As shown, a preferred embodiment of the present invention provides a battery cell disassembly device, comprising: a fixing frame 1 for mounting on the battery casing 5, the fixing frame 1 having a guide rod 2 arranged laterally; a sliding seat 3, the sliding seat 3 being movably mounted on the guide rod 2; and a pulling assembly 4, the pulling assembly 4 including a rotating seat 41, a screw 42, a connecting block 43, and a connecting nut 44. The rotating seat 41 is rotatably mounted on the sliding seat 3. Generally, the rotating seat 41 can rotate on the sliding seat 3, but cannot move axially. For example, the rotating seat 41 is connected to the sliding seat 3 via a bearing, the screw 42 is threadedly connected to the rotating seat 41, the screw 42 passes through the sliding seat 3, the connecting block 43 is fixed to the bottom of the screw 42, and the connecting nut 44 is installed at the bottom of the connecting block 43. There are two connecting nuts 44, which are used to connect one-to-one with the two electrodes of the battery cell 6. It is understood that the electrodes are provided with threads that cooperate with the connecting nuts 44.

[0017] The working principle of this embodiment is as follows: When in use, first, the fixing bracket 1 is set on the outer casing 5 of the battery. Then, the position of the sliding seat 3 is slidably adjusted so that the connecting block 43 is above the battery cell to be disassembled. Next, the two connecting nuts 44 are connected to the two electrodes of the battery cell. Then, the rotating seat 41 is rotated to drive the screw 42 to drive the connecting block 43 and the connecting nuts 44 to gradually rise until the battery cell is removed from the battery casing, thus realizing the disassembly of the battery cell. The operation is simple and the disassembly efficiency is high. There is no need to forcibly pull out the battery cell 6 with brute force, which effectively reduces accidental damage to the battery cell and surrounding components.

[0018] For example, see Figure 1The fixing frame 1 includes two upright plates 11 and two connecting rods 12. The upright plates 11 are arranged opposite each other in the horizontal direction. The connecting rods 12 are fixedly connected to the two upright plates 11 respectively. That is, the two upright plates 11 are fixedly connected by the connecting rods 12. The guide rod 2 is arranged between the two upright plates 11. One end of the guide rod 2 is fixedly connected to one of the upright plates 11 and the other end of the guide rod 2 is fixedly connected to the other upright plate 11. In use, the connecting rod 12 is placed on the top of the battery casing 5, so that the fixing frame 1 is mounted on the battery casing 5. Generally, the vertical sides of the upright plate 11 are provided with connecting rods 12 respectively. The connecting rods 12 are arranged in the horizontal direction, which can ensure the stability of the fixing frame 1 and avoid interference between the connecting rods 12 and the screws 42.

[0019] Generally, the battery casing 5 is a rectangular frame with an opening at the top, and multiple battery cells 6 are arranged in a matrix inside the battery casing 5. For example, see [link to example]. Figure 1 The bottom of the upright plate 11 is lower than the bottom of the connecting rod 12. The distance between the two upright plates 11 is the same as the length of the battery casing 5. The length direction of the battery casing 5 is horizontal. When the fixing bracket 1 is mounted on the battery casing 5, the two horizontal sides of the battery casing 5 are respectively attached to the upright plate 11, which facilitates the positioning connection between the fixing bracket 1 and the battery casing 5 and prevents the fixing bracket 1 from shifting during use. In addition, after the disassembly of multiple battery cells arranged horizontally is completed, the fixing bracket 1 can be moved vertically to disassemble another row of horizontally arranged battery cells.

[0020] For example, see Figure 2 The connecting block 43 has two connecting grooves 431 on one side of its lateral direction. The top and bottom of the connecting grooves 431 are open. The top of the connecting nut 44 has a connecting post 441, which is inserted into the connecting groove 431 one by one. The top of the connecting post 441 has a limiting block 442, and the bottom of the limiting block 442 abuts against the top of the connecting block 43. In use, the connecting nut 44 can be connected to the electrode of the battery cell 6 first, and then the position of the connecting block 43 can be adjusted so that the top of the connecting nut 44 is closed. The connecting post 441 is horizontally embedded in the connecting groove 431, and the bottom of the limiting block 442 abuts against the top of the connecting block 43, so that the connecting nut 44 is installed at the bottom of the connecting block 43 for easy operation. At this time, the drive screw 42 drives the connecting block 43 to rise, and the connecting block 43 will drive the limiting block 442 to rise together, thereby driving the connecting nut 44 to rise. When it is necessary to disassemble the connecting nut 44 from the connecting block 43, simply move the connecting post 441 horizontally to disengage it from the connecting groove 431. The operation is simple.

[0021] For example, see Figure 1-2The bottom of the sliding seat 3 is provided with a sliding groove 31, which slides and engages with the top of the guide rod 2. That is, the sliding groove 31 is set in the horizontal direction, and the shape of the sliding groove 31 is adapted to the shape of the top of the guide rod 2. By engaging with the guide rod 2 through the sliding groove 31, it is easy to position and connect the sliding seat 3 and the guide rod 2, and it can also ensure that the sliding seat 3 slides in the horizontal direction.

[0022] For example, see Figure 1 There are two guide rods 2 with a gap between them. The sliding seat 3 is placed on the two guide rods 2, which helps to stabilize the sliding seat 3. The screw 42 passes between the two guide rods 2. The layout is reasonable and prevents interference between the screw 42 and the guide rods 2.

[0023] For example, see Figure 1-2 The sliding seat 3 is fixedly connected to the limiting plate 32. The two guide rods 2 are respectively provided with limiting plates 32 on their opposite sides. The setting of the limiting plate 32 facilitates the positioning connection between the sliding seat 3 and the guide rod 2, and at the same time prevents the sliding seat 3 from moving laterally and disengaging from the guide rod 2, ensuring that the sliding seat 3 can move laterally together with the guide rod 2 and the fixed seat.

[0024] For example, see Figure 1-2 Multiple handles 411 are arranged along the outer periphery of the side of the rotating seat 41. Pushing the handles 411 can make the rotating seat 41 rotate, which is convenient for operation.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
