Description

Technical Field

[0001] The utility model belongs to the technical field of battery packs, and in particular relates to a battery pack side beam assembly and a battery pack. Background Art

[0002] The side beam assembly for the battery pack usually provides a fixed point for the battery pack to support and fix the battery pack cells, and may also serve as a structural support and protect the battery.

[0003] The existing side beam assembly for battery pack generally includes side beams and middle beams. The side beams are provided with four groups and a plurality of middle beams. The side beams and the middle beams are welded. After the four side beams are respectively provided on the four sides of the battery pack, the four side beams are welded, and the battery pack is fixed in the four side beams. The side beams are fixed by the fixing ears on the outside of the side beams, so as to install the battery pack. However, in actual use, due to different equipment models, the specifications of the battery packs used are different. When using a larger battery pack, since the welded side beams cannot be adjusted, when facing a larger battery pack, it is necessary to replace the new side beam assembly to fix the battery pack, which is more troublesome to use. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0024] The utility model provides Figure 1-5 A battery pack side beam assembly is shown, comprising:

[0025] The casing 1 is provided with two groups and the bottoms of the two groups of casings 1 are fixedly connected with fixing blocks 2;

[0026] A U-shaped frame 3 is provided with two groups, and the two groups of U-shaped frames 3 are respectively slidably connected to the two sides of the two groups of casings 1, and both ends of the U-shaped frame 3 are fixedly connected with sliding rods 4, and the sliding rods 4 are slidably connected to the sliding grooves 5 in the casing 1. A gear 6 is rotatably connected between the two groups of sliding rods 4 in one group of sliding grooves 5, and the gear 6 is meshed with a plurality of teeth 7 provided on the surface of the sliding rod 4. The U-shaped frame 3 is driven to move by the meshing of the gear 6 and the teeth 7 to adjust the spacing between the U-shaped frames 3.

[0027] A rotating rod 8 is fixedly connected to the top of the gear 6, and the other end of the rotating rod 8 rotates through the casing 1 and extends to the top of the casing 1. One end of the rotating rod 8 located at the top of the casing 1 is fixedly connected to a turntable 9. By rotating the turntable 9, the rotating rod 8 is driven to rotate, thereby driving the gear 6 in the slide groove 5 to rotate. Since the gear 6 is meshed with the teeth 7 on the surface of the slide rod 4, the gear 6 will drive the two groups of slide rods 4 to move when it rotates. When the slide rod 4 moves, it drives the two groups of U-shaped frames 3 away from each other, thereby expanding the installation space between the U-shaped frames 3.

[0028] A plurality of threaded holes 10 are provided in an annular manner on the surface of the casing 1 and at the bottom of the turntable 9. A first bolt 11 is rotatably connected to the surface of the turntable 9 and the first bolt 11 is threadedly connected to the threaded hole 10. After adjustment is completed, the first bolt 11 is rotated and the first bolt 11 is threadedly connected to the threaded hole 10 on the surface of the casing 1, thereby limiting the turntable 9 after adjustment to prevent the turntable 9 from rotating due to unexpected circumstances, causing the U-shaped frame 3 to loosen.

[0029] A plug 12 is provided on one side of one group of U-shaped frames 3, and a plurality of fixing ears 13 are provided on the surface of the U-shaped frames 3. The surface of the fixing ears 13 is provided with mounting holes 14. The U-shaped frames 3 can be fixed and installed by fixing parts passing through the mounting holes 14 on the surfaces of the fixing ears 13, so as to install the battery pack body 18 between the U-shaped frames 3.

[0030] The fixed block 2 is provided with a movable groove 15, and a positioning block 16 is slidably connected in the movable groove 15. A second bolt 17 is provided on the surface of the fixed block 2. The second bolt 17 rotates through the fixed block 2 and is rotatably connected to the positioning block 16 through a bearing 20 installed in 16. The second bolt 17 is rotated, and the second bolt 17 drives the positioning block 16 to slide in the movable groove 15, so that the positioning block 16 moves to one end close to the battery pack body 18 and is plugged into the positioning groove 19 on the surface of the battery pack body 18, thereby limiting the battery pack body 18.

[0031] A battery pack comprises the battery pack side beam assembly described above.

[0032] The battery pack also includes a battery pack body 18, and two groups of positioning grooves 19 are provided on the surface of the battery pack body 18. The positioning block 16 is plugged into the positioning groove 19, and the plug 12 is electrically connected to the battery pack body 18. Since the plug 12 is electrically connected to the battery pack body 18, the battery pack body 18 can be charged by plugging the plug 12 into a socket.

[0033] The battery pack side beam assembly and the battery pack, when the U-shaped frame 3 needs to be adjusted, the turntable 9 is rotated, and the turntable 9 drives the rotating rod 8 to rotate, thereby driving the gear 6 in the slide groove 5 to rotate. Since the gear 6 is meshed with the teeth 7 on the surface of the slide rod 4, the gear 6 will drive the two groups of slide rods 4 to move when it rotates, and when the slide rods 4 in one group of slide grooves 5 move, it will drive the slide rods 4 in the other group of slide grooves 5 to move, so that when the two groups of slide rods 4 move, they drive the two groups of U-shaped frames 3 away from each other, thereby expanding the installation space between the U-shaped frames 3 to meet the installation of battery pack bodies 18 of different specifications. When the adjustment is completed, the first bolt 11 is rotated, and the first bolt 11 is screwed with the threaded hole 10 on the surface of the shell 1, so as to limit the adjusted turntable 9 to prevent the turntable 9 from rotating due to unexpected circumstances, causing the U-shaped frames 3 to loosen.

[0034] After installing the battery pack body 18 between the two adjusted U-shaped frames 3 and the casing 1, the second bolt 17 is rotated, and the second bolt 17 drives the positioning block 16 to slide in the movable groove 15, so that the positioning block 16 moves to the end close to the battery pack body 18 and is plugged into the positioning groove 19 on the surface of the battery pack body 18, thereby limiting the battery pack body 18 to prevent the battery pack body 18 from falling off from the U-shaped frame 3. After limiting the battery pack body 18, the battery pack body 18 can be fixed to the U-shaped frame 3 by a fixing part to prevent the battery pack body 18 from loosening and affecting use.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
