[0012] Beneficial effects

[0013] This invention provides a lithium-ion battery casing for golf bag vehicles. Compared with the prior art, it has the following advantages:

[0014] This invention relates to a lithium-ion battery casing for golf carts. Through a portable extension component, pulling the handle on the placement box causes the column to move upwards within the moving slot, thereby moving the moving plates upwards on the inner wall of the battery casing. During this upward movement, the two moving plates pull the placement box out of the battery casing. Then, rotating the placement box causes its bottom to fit against the top of the limiting plate, allowing the limiting plate to support the horizontally positioned placement box. The golf cart lithium battery is then placed into the placement box and onto both sides of the inner wall of the battery casing through the placement slot. Rotating the placement box again and pressing the handle causes the four moving plates to push the placement box into the battery casing. To remove the golf cart lithium battery, the placement box is moved out of the battery casing, and the moving column is pushed, causing the golf cart lithium battery to detach from the placement box. Rotating the placement box allows the golf cart lithium battery to be removed from both sides of the inner wall of the battery casing. This solves the problem of inconveniently removing the golf cart lithium battery from the casing, allowing users to easily remove the battery without professional tools or complicated operations, thus improving efficiency.

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.

[0021] Please see Figures 1-4 This utility model provides two technical solutions, specifically including the following embodiments:

[0022] A lithium-ion battery casing for a golf bag cart includes a battery casing body 1. The top of the battery casing body 1 has two identical casing covers 3. Multiple heat dissipation holes 2 are provided on the front and rear outer surfaces of the battery casing body 1, arranged in a matrix. Inside the battery casing body 1 are two storage boxes 4. Handles 5 are fixedly installed on the opposing outer surfaces of the two storage boxes 4. Inside the battery casing body 1 is a portable extension assembly, which includes four movable plates 7 arranged symmetrically. The outer surfaces of two corresponding movable plates 7 are rotatably connected to the outer surfaces of the storage boxes 4. A snap-fit ​​assembly is provided on the outer surface of one of the two casing covers 3 facing each other. The portable extension assembly allows the golf bag cart lithium battery inside the battery casing body 1 and the storage boxes 4 to be removed. The multiple heat dissipation holes 2 allow for heat dissipation of the golf bag cart lithium battery inside the battery casing body 1.

[0023] Furthermore, two identical movable grooves 10 are provided on the inner walls of the front and rear sides of the battery casing body 1. A column 16 is slidably connected inside each of the four movable grooves 10. The column 16 is sleeved with the lower part of the corresponding movable plate 7. The column 16 moves upward in the movable groove 10, thereby driving the movable plate 7 to move upward on the inner wall of the battery casing body 1.

[0024] Furthermore, each of the two placement boxes 4 has a placement groove 6 on one outer surface, and each of the two placement boxes 4 has a movable column 11 movably fitted on the other outer surface. After the placement box 4 is moved out of the battery casing body 1, it pushes the movable column 11, thereby causing the golf bag car lithium battery to detach from the placement box 4.

[0025] Furthermore, movable grooves 8 are provided on the top of both the front and rear sides of the battery casing body 1. Two movable blocks 12 are slidably connected inside each movable groove 8. The top of the two movable blocks 12 on the front and rear sides are fixedly connected to the bottom of the casing cover 3. Push handles 15 are fixedly installed on the opposite outer surfaces of the two casing covers 3. Pulling the push handles 15 on both sides of the casing cover 3 causes the two casing covers 3 to move relative to each other under the sliding cooperation of the movable grooves 8 and the movable blocks 12.

[0026] Furthermore, the snap-fit ​​assembly includes a snap-fit ​​plate 13 and a snap-fit ​​groove 14. The snap-fit ​​plate 13 is fixedly connected to the outer surface of the other side of one of the outer casing covers 3, and the snap-fit ​​groove 14 is opened on the outer surface of the other side of the outer casing cover 3. The snap-fit ​​plate 13 and the snap-fit ​​groove 14 are movably snap-fitted together. When the snap-fit ​​plate 13 is inserted into the snap-fit ​​groove 14 and snap-fitted together, the two outer casing covers 3 cover the top of the battery casing body 1.

[0027] Furthermore, the outer surfaces of the four movable plates 7 facing away from each other are fixedly connected to limit plates 9. The tops of the front and rear limit plates 9 are movably connected to the bottoms of the adjacent placement boxes 4. Rotating the placement box 4 causes the bottom of the placement box 4 to fit against the top of the limit plate 9, so that the limit plate 9 can support the horizontal placement box 4.

[0028] During operation, pulling the push handles 15 on both sides of the outer casing 3 causes the two outer casing 3 to move relative to each other under the sliding cooperation of the movable groove 8 and the movable block 12. Pulling the handle 5 on the placement box 4 causes the column 16 to move upward in the moving groove 10, thereby driving the moving plate 7 to move upward on the inner wall of the battery casing body 1. During the upward movement of the two moving plates 7, the placement box 4 is pulled out from the battery casing body 1. After being pulled out, the placement box 4 is in a vertical state. Then, the placement box 4 is rotated so that the bottom of the placement box 4 fits against the top of the limiting plate 9, so that the limiting plate 9 can support the horizontal placement box 4. Then, the golf bag cart lithium battery is placed into the placement box 4 and the inner wall of the battery casing body 1 through the placement groove 6. Then rotate the placement box 4 again and press the handle 5. With the cooperation of the four moving plates 7, the placement box 4 enters the battery casing body 1. Move the two casing covers 3 again to make them move relative to each other. When the snap plate 13 is inserted into the snap slot 14 and snapped in place, the two casing covers 3 cover the top of the battery casing body 1. When it is necessary to remove the golf bag cart lithium battery, the placement box 4 can be moved out of the battery casing body 1 and the movable column 11 can be pushed to make the golf bag cart lithium battery detach from the placement box 4. After rotating the placement box 4, the golf bag cart lithium battery on both sides of the inner wall of the battery casing body 1 can be removed. Multiple heat dissipation holes 2 can dissipate heat from the golf bag cart lithium battery inside the battery casing body 1.
