Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a battery shell with good sealing effect, comprising: a battery upper shell 1, a battery lower shell 2 is slidably connected inside a card slot opened at the top of the battery upper shell 1, a sealing ring 3 is fixedly connected to one side of the battery upper shell 1, a fixing mechanism 4 is arranged inside the battery upper shell 1, the fixing mechanism 4 comprises a card block 41, one side of the card block 41 is fixedly connected to the battery lower shell 2, the card block 41 is slidably connected to the battery upper shell 1 and the sealing ring 3, a fixing block 42 is arranged on one side of the card block 41, the card block 41 is slidably connected to the fixing block 42, the bottom of the fixing block 42 is fixedly connected to the battery upper shell 1, and one side of the fixing block 42 is fixedly connected to a first U The first U-shaped block 43 is provided with a spring sheet 44 on one side, one end of the spring sheet 44 is fixedly connected to the first U-shaped block 43, the other end of the spring sheet 44 is fixedly connected to the first connecting block 45, the first connecting block 45 is slidably connected to the first U-shaped block 43, one side of the first connecting block 45 is fixedly connected to a sliding block 46, the sliding blocks 46 are both slidably connected to the battery upper shell 1 and the first U-shaped block 43, one side of the sliding block 46 is fixedly connected to an anti-sliding block 47, the other side of the sliding block 46 is fixedly connected to a second connecting block 48, one side of the second connecting block 48 is fixedly connected to a buckle 49, the buckle 49 is slidably connected to the clamping block 41, and one side of the sliding block 46 is provided with an auxiliary mechanism 5.

[0024] In this embodiment, after the staff installs the battery lower shell 2 on the battery upper shell 1, one side of the sealing ring 3 connected to one side of the battery upper shell 1 is in close contact with one side of the battery lower shell 2. At this time, one side of the card block 41 connected to one side of the battery lower shell 2 is in close contact with the sealing ring 3, which is conducive to reducing the water vapor in the air from entering the battery shell through the gap between the battery upper shell 1 and the battery lower shell 2, thereby reducing the impact of water vapor on the battery service life to a certain extent. Before the battery lower shell 2 is installed on the battery upper shell 1, the staff presses the anti-sliding block 47 with his fingers, and slides the two sliding blocks 46 connected to the same side of the two anti-sliding blocks 47, so that the two sliding blocks 46 slide in the card slot opened on one side of the battery upper shell 1 and gradually approach each other. The anti-sliding block 47 increases the friction between the staff's fingers and it, which is conducive to the staff sliding the sliding block 46. When the sliding block 46 slides, the sliding block 46 drives the first connecting block 45 connected to one side thereof to slide. While the first connecting block 45 slides, it compresses the spring sheet 44. While the sliding block 46 slides, The block 46 drives the second connecting block 48 connected to one side thereof to slide, so that the second connecting block 48 drives the buckle 49 connected to it to slide, until the buckle 49 does not hinder the block 41 from sliding between the battery upper shell 1 and the sealing ring 3. At this time, the staff installs the battery lower shell 2 in the slot opened on the top of the battery upper shell 1, until the sealing ring 3 is in close contact with one side of the battery lower shell 2 and the block 41 is in close contact with one side of the sealing ring 3. At this time, the buckle 49 is aligned with the slot provided on one side of the block 41, and the staff releases the press. The anti-sliding block 47 allows the compressed spring sheet 44 to recover, and the spring sheet 44 drives the first connecting block 45 and the sliding block 46 to recover. The recovery of the sliding block 46 drives the second connecting block 48 and the buckle 49 to recover. During the recovery process, the buckle 49 gradually slides into the inside of the card slot provided on one side of the card block 41, thereby fixing the upper battery shell 1 and the lower battery shell 2. The staff releases the pressed anti-sliding block 47, and the buckle 49 automatically fixes the upper battery shell 1 and the lower battery shell 2. The operation is simple, which is convenient for the staff to use.

[0025] Example 2

[0026] like Figure 1 , Figure 4 and Figure 5 As shown, the auxiliary mechanism 5 includes a second U-shaped block 51, one side of the second U-shaped block 51 is fixedly connected to the sliding block 46, a sliding groove 52 is provided on one side of the fixed block 42, a pulley 53 is provided inside the sliding groove 52, the pulley 53 is movably connected to the fixed block 42, a fixed tube 54 passes through the inside of the pulley 53, the fixed tube 54 is rotatably connected to the pulley 53, and the fixed tube 54 is fixedly connected to the second U-shaped block 51.

[0027] In this embodiment, when the sliding block 46 slides, it indirectly drives the pulley 53 to slide and rotate. On the one hand, it is beneficial for the staff to drive the two sliding blocks 46 to slide and gradually approach each other in the card slot opened on one side of the battery upper shell 1 by pressing the two anti-sliding blocks 47. On the other hand, it is beneficial for the two spring pieces 44 to drive the two sliding blocks 46 and the two buckles 49 to move simultaneously when they are restored, thereby increasing the overall smoothness of the sliding process of the sliding block 46 to a certain extent. A pulley 53 is provided inside the slide groove 52. When the sliding block 46 slides, the sliding block 46 drives the second U-shaped block 51 connected thereto to move, and the second U-shaped block 51 drives the fixed tube 54 connected thereto to move, thereby driving the pulley 53 connected to the fixed tube 54 to move, and the pulley 53 contacts one side of the inner wall of the slide groove 52. When the pulley 53 moves, it rotates, thereby increasing the smoothness of the sliding process of the sliding block 46 to a certain extent.

[0028] Working principle:

[0029] like Figure 1-Figure 5 As shown, first, the staff member presses the two anti-sliding blocks 47 with his fingers, so that the two anti-sliding blocks 47 drive the two sliding blocks 46 to slide in the card slot opened on one side of the battery upper shell 1 and gradually approach each other, and the two sliding blocks 46 drive the two first connecting blocks 45 to slide, and compress the two spring sheets 44 at the same time, while the two sliding blocks 46 slide, the second connecting block 48 connected to itself drives the two buckles 49 to slide, so that the buckles 49 will not hinder the card block 41 from sliding between the battery upper shell 1 and the sealing ring 3, and then, after the staff member installs the battery lower shell 2 on the battery upper shell 1, at this time, one side of the battery lower shell 2 is in close contact with the sealing ring 3, one side of the card block 41 is in close contact with the sealing ring 3, and the two buckles 49 are respectively aligned with the card slots provided on the two card blocks 41, and the staff member The operator loosens the anti-sliding block 47 to restore the two compressed spring sheets 44. The two spring sheets 44 drive the two sliding blocks 46 to move through the first connecting block 45 connected to themselves. The two sliding blocks 46 drive the two buckles 49 to move through the second connecting block 48 connected to themselves. The two buckles 49 gradually slide into the inside of the card slots provided on the two card blocks 41. Finally, when the two sliding blocks 46 slide, the two sliding blocks 46 drive the two pulleys 53 to move and move away from each other through the second U-shaped block 51 connected to themselves and cooperate with the two fixing pipes 54. The two pulleys 53 are in contact with one side of the inner wall of the slide groove 52, so that the two pulleys 53 rotate while moving inside the slide groove 52 until the two pulleys 53 stop moving, and the fixation between the battery upper shell 1 and the battery lower shell 2 is completed.
