[0020] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0021] Please see Figure 1 A battery pack structure 10 for easy replacement of battery components includes: a frame 100 and a battery module 200. The frame 100 includes a slide rail assembly 110 and a plurality of receiving cavities 120. Each receiving cavity 120 is arranged around the slide rail assembly 110. The slide rail assembly 110 includes a plurality of slide rails 111, and each slide rail 111 is arranged in a one-to-one correspondence with each receiving cavity 120. The battery module 200 includes a plurality of battery components 210. Each battery component 210 is respectively disposed in each receiving cavity 120. A groove 211 is provided on one side of the battery component 210, and the groove 211 is slidably connected to the slide rail 111.

[0022] It should be noted that by disassembling the battery module 200 into battery components 210, and by creating multiple accommodating cavities 120 within the frame 100, each battery component 210 can be installed in its respective cavity 120. Since the weight and volume of a single battery component 210 are smaller than the overall weight and volume of the battery module 200, it is easier to manually replace the battery components 210 on the frame 100. Guide rails are provided on the frame 100, and each accommodating cavity 120 is arranged around a slide rail assembly 111, which includes multiple slide rails. 111, and then each slide rail 111 is set to correspond one-to-one with each receiving cavity 120, so that the battery assembly 210 on each receiving cavity 120 corresponds one-to-one with each slide rail 111. By opening a sliding groove 211 on one side of the battery assembly 210, and then slidingly connecting the sliding groove 211 with the slide rail 111, each battery assembly 210 is slidably connected to the frame 100. When the battery assembly 210 is depleted, the sliding connection structure between the battery assembly 210 and the frame 100 can further facilitate manual replacement of each battery assembly 210 on the frame 100.

[0023] Please refer to it again. Figure 1 In one embodiment, the frame 100 further includes a first positioning member 130 and a second positioning member 140. The first positioning member 130 is connected to one end of the slide rail assembly 110, and the second positioning member 140 is connected to the other end of the slide rail assembly 110. This arrangement facilitates manual installation of each battery assembly 210 in the receiving cavity 120 via the first positioning member 130, while the second positioning member 140 enables precise installation of each battery assembly 210, thereby improving the stability of each battery assembly 210.

[0024] Please refer to it again. Figure 1 In one embodiment, the battery pack further includes a plurality of first fixing members 300, the number of which is the same as the number of battery packs 210. Each first fixing member 300 is disposed on the side of the first positioning member 130 away from the receiving cavity 120. One end of the battery pack 210 is provided with a first fixing part 212. The first fixing member 300 and the first fixing part 212 are detachably connected. The battery pack 210 is fixed on the frame 100 by the connection between the first fixing member 300 and the first fixing part 212. When the battery pack 210 needs to be replaced, since the first fixing member 300 and the first fixing part 212 of the battery pack 210 are detachably connected, it is easy to manually remove the battery pack 210 from the frame 100. At the same time, the first fixing member 300 can be reused, which helps to reduce the cost of the battery pack.

[0025] Please refer to it again. Figure 1 In one embodiment, the first fixing member 300 has a first through hole 310, and the first fixing part 212 is provided with a first bolt connector 212a. The first bolt connector 212a passes through the first through hole 310 and is connected to the first fixing member 300 by a nut. The bolt and nut fixing method makes the connection between the first fixing member 300 and the first fixing part 212 more stable. At the same time, the bolt and nut fixing method facilitates the manual removal of the battery assembly 210 on the frame 100.

[0026] Please refer to it again. Figure 1In one embodiment, the battery assembly 210 further includes a plurality of second fixing members 400. Each second fixing member 400 is disposed on the side of the second positioning member 140 away from the receiving cavity 120. The other end of the battery assembly 210 is provided with a second fixing part 213. The second fixing member 400 and the second fixing part 213 are detachably connected. The connection between the second fixing member 400 and the second fixing part 213 further fixes the battery assembly 210 to the frame 100. Furthermore, the second fixing member 400 and the first fixing member 300 fix both ends of the battery assembly 210 to form a pull structure, thereby improving the stability of the battery assembly 210 within the frame 100 and preventing the disassembled battery assembly 210 from shaking within the frame 100, which would affect the safety performance of the battery pack. Since the second fixing member 400 and the second fixing part 213 of the battery assembly 210 are detachably connected, it is convenient to manually remove the battery assembly 210 from the frame 100. At the same time, the second fixing member 400 can be reused, which helps to reduce the cost of the battery pack.

[0027] Please refer to it again. Figure 1 In one embodiment, the second fixing member 400 has a second through hole 410, and the second fixing part 213 is provided with a second bolt connector 213a. The second bolt connector 213a passes through the second through hole 410 and is connected to the second fixing member 400 by a nut. The bolt and nut fixing method makes the connection between the second fixing member 400 and the second fixing part 213 more stable. At the same time, the bolt and nut fixing method facilitates the manual removal of the battery assembly 210 on the frame 100.

[0028] Please refer to it again. Figure 1 In one embodiment, the frame 100 further includes a third positioning member 150, which is disposed between the first positioning member 130 and the second positioning member 140. The third positioning member 150 is used to further precisely install each battery assembly 210. At the same time, the third positioning member 150 is disposed in the middle of the frame 100, so that the third positioning member 150 can also improve the support strength of the frame 100, thereby making the frame 100 less prone to deformation.

[0029] Please refer to it again. Figure 1 In one embodiment, the frame 100 further includes a plurality of support bars 160, which are disposed on the side of the accommodating cavity 120 away from the slide rail 111, further improving the support strength of the frame 100 and preventing the frame 100 from deforming.

[0030] Please refer to it again. Figure 1 In one embodiment, the battery assembly 210 has multiple hollow areas. Since the primary battery in the battery assembly 210 generates a lot of heat when supplying power, the hollow areas can accelerate the heat dissipation and prevent the heat from affecting the power supply performance of the primary battery.

[0031] Please refer to it again. Figure 1 In one embodiment, a protection board 500 is also included. The protection board 500 is disposed on one side of the frame 100 to avoid causing inconvenience to the personnel during the replacement of the battery assembly 210. At the same time, it avoids the replacement of the battery assembly 210 from affecting the function of the protection board 500, so that the protection board 500 of the battery pack can be reused, reducing the cost of the battery pack. The protection board 500 is electrically connected to the battery module 200 and is used to prevent the battery module 200 from being over-discharged, over-temperatured, over-currented, or short-circuited.

[0032] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
