The protective box is used to protect the sodium-ion batteries to prevent them from being damaged by impact. However, when sodium-ion batteries are currently fixed to the inner cavity of the protective box, they need to be fixed to the bottom of the inner cavity of the protective box with multiple bolts, which requires the use of auxiliary tools during the installation process. This makes the operation more complicated and time-consuming. Therefore, we propose a sodium-ion battery fixed protection structure to solve the above problems. Utility Model Content

[0024] In a further embodiment, referring to Figure 2-Figure 5The fixing member 3 includes a carrying plate 31 and a positioning plate 33. The inner side wall of the protection box 1 is rotatably connected to the carrying plate 31 through a bearing seat. The battery 6 is placed on the upper end of the carrying plate 31. The positioning plate 33 is fixedly connected to the upper end of the carrying plate 31. The positioning plate 33 abuts against the side wall of the battery 6. The end of the positioning plate 33 close to the battery 6 is fixedly connected to a fixing block 35. A fixing groove 61 is opened on the side wall of the battery 6. The fixing block 35 is located in the fixing groove 61 and is engaged with the fixing groove 61.

[0025] In this embodiment, when the battery 6 is placed on the supporting plate 31, the supporting plate 31 is forced to rotate and then drives the positioning plate 33, so that the positioning plate 33 abuts against the side wall of the battery 6. The rotating positioning plate 33 drives the fixing block 35, so that the fixing block 35 is engaged in the fixing groove 61, thereby preliminarily achieving the effect of fixing the battery 6. Through the mutual cooperation of the gravity of the battery 6 itself and the fixing part 3, the effect of automatically fixing the battery 6 can be achieved.

[0026] In a further embodiment, referring to Figure 3-Figure 6 A card slot 32 is formed on one end surface of the carrying plate 31 away from the side wall of the protection box 1, and the card slot 32 is located below the positioning plate 33. The locking assembly 4 includes a fixed seat 41 and a card block 43. The bottom end of the interior of the protection box 1 is fixedly connected to the fixed seat 41, and a transmission rod 42 is slidably connected inside the fixed seat 41. An end of the transmission rod 42 close to the center of the protection box 1 is fixedly connected to a top block 44, and an end of the transmission rod 42 away from the top block 44 is fixedly connected to the card block 43. The card block 43 and the card slot 32 are engaged with each other, and an end of the top block 44 close to the card block 43 is fixedly connected to a spring 45, and an end of the spring 45 away from the top block 44 is fixedly connected to the fixed seat 41.

[0027] In this embodiment, the block 43 is driven to move by moving the transmission rod 42 . When the block 43 moves into the slot 32 , the fixing member 3 is fixed, thereby further achieving the effect of fixing the battery 6 .

[0028] In a further embodiment, referring to Figure 3-Figure 4 The driving assembly 5 includes a worm wheel 53 and a worm 51. The worm 51 is rotatably connected inside the protection box 1. The bottom end of the protection box 1 is rotatably connected to a rotating rod 52. The side wall of the rotating rod 52 is fixedly connected to a worm wheel 53 and a rotating disk 54. The worm wheel 53 is located at the lower end of the rotating disk 54. The worm wheel 53 is meshed with the worm 51. The side wall of the rotating disk 54 is fixedly connected with protrusions 55 at equal intervals. There are four groups of protrusions 55, which are all in contact with the top block 44.

[0029] In this embodiment, the worm gear 53 is driven to rotate by rotating the worm 51, the rotation of the worm gear 53 drives the rotating rod 52 to rotate, the rotation of the rotating rod 52 drives the rotating disk 54 to rotate, the rotation of the rotating disk 54 drives the protrusion 55 to move, and the moving protrusion 55 cancels the abutment against the top block 44, thereby providing power for the movement of the transmission rod 42.

[0030] In a further embodiment, referring to Figure 2-Figure 5 One end of the positioning plate 33 close to the inner wall of the protection box 1 is fixedly connected with a first magnet 34, and the inner wall of the protection box 1 is fixedly connected with a second magnet 7, and the first magnet 34 and the second magnet 7 cooperate with each other.

[0031] In this embodiment, when the battery 6 is taken out, the fixing block 35 slides inside the fixing groove 61, thereby driving the fixing member 3 to rotate toward the inner wall of the protective box 1. Since the magnetic poles of the first magnet 34 and the second magnet 7 on the opposite sides are in opposite directions, the first magnet 34 and the second magnet 7 attract each other, and then the fixing member 3 is fixed to the side wall of the protective box 1.

[0032] The working principle of the utility model is as follows: the worm gear 53 is driven to rotate by rotating the worm screw 51, and the worm gear 53 is driven to rotate the rotating rod 52, and the rotating rod 52 is driven to rotate the rotating disk 54, and the rotating disk 54 is driven to move the protrusion 55, and the moving protrusion 55 cancels the contact with the top block 44. This is to push the top block 44 to move in the direction of the rotating disk 54 under the condition that the spring 45 recovers the deformation, and the top block 44 moves to drive the transmission rod 42 to move, and the transmission rod 42 moves to drive the card block 43 to move, so that the card block 43 and the card slot 32 fall off and engage, and then the battery 6 is taken out upward from the inner cavity of the protection box 1. In the process of the battery 6 being taken out, the fixed block 35 slides inside the fixed slot 61, thereby driving the fixing member 3 to rotate toward the inner wall direction of the protection box 1. Since the magnetic poles of the first magnet 34 and the second magnet 7 are opposite in direction, the first magnet 34 and the second magnet 7 attract each other, and then the fixing member 3 is fixed to the side wall of the protection box 1.

[0033] When fixing the battery 6 in the cavity of the protective box 1, it is only necessary to place the battery 6 on the fixing member 3, preliminarily fix the battery 6 through the fixing member 3, and then rotate the worm 51 to abut on the top block 44 through the protrusion 55 on the rotating disk 54, so as to push the top block 44 to move, and then drive the clamping block 43 and the clamping slot 32 to engage with each other, so as to achieve the effect of fixing the battery 6, thereby solving the problem that when the sodium ion battery is fixed to the inner cavity of the protective box, it is necessary to use multiple bolts to fix the sodium ion battery to the bottom end of the inner cavity of the protective box, so that auxiliary tools need to be used during the installation process, so the operation is more complicated and requires a lot of time.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
