All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment: As Figures 1-7 shown, the present utility model provides a battery pack convenient for assembly, including a metal shell 1. A metal cover plate 11 is provided at the top of the metal shell 1. A plurality of battery bodies 12 distributed in an array are arranged inside the metal shell 1. Mounting grooves 2 distributed mirror-image are formed at the top of the metal shell 1. Mounting blocks 21 distributed mirror-image are fixedly provided at the bottom end of the metal cover plate 11. The mounting grooves 2 and the mounting blocks 21 are used in cooperation. First springs 22 distributed mirror-image are arranged inside the metal shell 1. Moving plates 23 are fixedly provided at one ends of the first springs 22 close to the mounting grooves 2. The other ends of the first springs 22 away from the moving plates 23 are fixedly installed on the inner wall of the metal shell 1. Blocks 24 are fixedly provided on one side walls of the moving plates 23 away from the first springs 22. Slots 25 are formed in the mounting blocks 21. The blocks 24 and the slots 25 are used in cooperation.

[0021] Stabilizing plates 31 distributed mirror-image are fixedly provided on the surfaces of the moving plates 23. Second springs 3 are fixedly provided on one sides of the stabilizing plates 31. The other ends of the second springs 3 away from the stabilizing plates 31 are fixedly installed on the inner wall of the metal shell 1.

[0022] Reinforcing blocks 32 are fixedly provided on one side walls of the stabilizing plates 31 away from the second springs 3. Reinforcing grooves 33 distributed mirror-image are formed in the mounting blocks 21. The reinforcing blocks 32 and the reinforcing grooves 33 are used in cooperation.

[0023] Connection plates 210 are fixedly provided on one sides of the moving plates 23. Pushing blocks 220 are fixedly provided at one ends of the connection plates 210 away from the moving plates 23.

[0024] A plurality of first fixing holes 4 distributed evenly are formed in the metal cover plate 11. A plurality of second fixing holes 41 distributed evenly are formed at the top of the metal shell 1. The first fixing holes 4 and the second fixing holes 41 are used in cooperation.

[0025] A placement groove 6 is formed at the bottom of the metal cover plate 11; by providing the placement groove 6, it is convenient for the operator to place the power cord on the battery body 12.

[0026] Sealing plates 7 distributed in mirror images are fixedly arranged on both sides of the connecting plate 210. Sealing grooves 71 distributed in mirror images are formed inside the metal housing 1, and the sealing plates 7 are respectively slidably arranged in the corresponding sealing grooves 71. By providing the sealing plates 7 and the sealing grooves 71, the effect of protecting the first spring 22 and the second spring 3 is achieved.

[0027] Guide rods 230 are slidably inserted into the connecting plate 210, and both ends of the guide rods 230 are fixedly installed on the inner wall of the metal housing 1. By providing the guide rods 230, the effect of limiting the connecting plate 210 is achieved, enabling the connecting plate 210 to move stably.

[0028] Working principle: First, when assembling the battery pack, first install and fix multiple battery bodies 12 in the metal housing 1. Subsequently, drive the connecting plate 210 to move by driving the dial block 220. The connecting plate 210 drives the moving plate 23 and the stabilizing plate 31 to move. During the movement of the moving plate 23 and the stabilizing plate 31, the first spring 22 and the second spring 3 are compressed and deformed. At the same time, the moving plate 23 and the stabilizing plate 31 drive the clamping block 24 and the reinforcing block 32 to move during the movement. When the clamping block 24 and the reinforcing block 32 completely leave the installation groove 2, insert the installation blocks 21 into the corresponding installation grooves 2 respectively. When the installation blocks 21 completely enter the corresponding installation grooves 2, remove the driving force on the dial block 220. At this time, the first spring 22 and the second spring 3 elastically reset. Driven by the reset elastic force of the first spring 22 and the second spring 3, the moving plate 23 and the stabilizing plate 31 move. The moving plate 23 and the stabilizing plate 31 drive the clamping block 24 and the reinforcing block 32 to move. When the clamping block 24 completely enters the card slot 25 and the reinforcing block 32 completely enters the reinforcing groove 33, the pre-installation between the metal cover plate 11 and the metal housing 1 is completed. Subsequently, install and fix the metal cover plate 11 and the metal housing 1 with screws through the first fixing hole 4 and the second fixing hole 41.

[0029] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
