Description

Technical Field

[0001] The present invention relates to the technical field of battery brackets, and in particular to a battery bracket and a connecting piece with a welding short-circuit prevention function. Background Art

[0002] A battery holder is a bracket-type structural component used in the prior art to arrange and install multiple batteries. The battery holder is generally divided into a bottom holder and a top holder. During use, multiple batteries can be arranged and placed between the bottom holder and the top holder to achieve stability and protection of the batteries during use. After multiple batteries are installed on the battery holder, metal connecting plates are usually used to electrically connect the multiple batteries to facilitate the centralized use of multiple batteries.

[0003] In the prior art, the positive and negative poles of some batteries are located on one side (for example, the 4680 battery). The positive pole of this type of battery is a protrusion in the center, while the negative pole of the battery is the annular area outside the positive pole. When using a connecting piece to electrically connect the positive poles and accessories of multiple batteries, it is necessary to make the positive pole section of the connecting piece abut against the positive pole of the battery, and then make the negative pole section of the connecting piece contact with the negative pole of the battery, and then use a spot welder to weld the negative pole section of the connecting piece to the negative pole of the battery. However, because the positive pole section of this type of connecting piece spans the negative pole of the battery and then abuts against the positive pole of the battery, this results in a short circuit problem when welding the negative pole section of the connecting piece to the negative pole of the battery. Summary of the Invention

[0004] The present invention provides a battery holder and a connecting piece with a welding short-circuit prevention function, which solves the problem in the prior art that a short circuit easily occurs between the connecting piece and the battery during the welding connection between the battery holder and the connecting piece and the positive and negative electrodes of the battery.

[0034] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0035] like Figures 1 to 11 As shown, this embodiment provides a battery holder with a welding short-circuit prevention function, including a bottom holder 1 and a top holder 2. The bottom holder 1 is provided with a plurality of placement circular grooves 3, and the top holder 2 is provided with a plurality of placement circular grooves 4. The placement circular grooves 3 and the placement circular grooves 4 correspond one to one. When multiple batteries need to be installed, the batteries are placed between the corresponding placement circular grooves 3 and placement circular grooves 4.

[0036] It also includes an arc-shaped piece 5, each of which is provided with four detachable arc-shaped pieces 5 in the placement circular groove 2 4, and the four arc-shaped pieces 5 are evenly distributed in the placement circular groove 2 4. There are multiple plastic connection points 14 fixedly connected between the arc-shaped piece 5 and the placement circular groove 2 4, and multiple plastic connection points 2 15 are fixedly connected on the side walls of two adjacent arc-shaped pieces 5. The multiple plastic connection points 2 15 located on both sides correspond one to one, and the corresponding two plastic connection points 2 15 are fixedly connected. The arc-shaped piece 5 is made of plastic material and has good insulation. The arc-shaped piece 5 is fixedly connected to the placement circular groove 2 4 through the plastic connection point 1 14, and the four arc-shaped pieces 5 are connected to each other in the placement circular groove 2 4 through multiple plastic connection points 2 15, so that the four arc-shaped pieces 5 remain fixed in the placement circular groove 2 4, and the plastic connection point 1 14 and the plastic connection point 2 15 are both easy to tear and deform, which also facilitates the user to remove the corresponding arc-shaped piece 5 from the placement circular groove 2 4.

[0037] Each of the two circular grooves 4 is provided with a disassembly structure, which includes a rotating sleeve 6, a rotating ring 7, a disassembly plate 8 and a meshing member. The two circular grooves 4 are fixedly connected with a rotating sleeve 6, a rotating ring 7 is rotatably provided in the rotating sleeve 6, and four indicator strips 13 are provided on the rotating ring 7. The disassembly plate 8 is fixedly connected to the rotating ring 7 through a plastic strip 27. A plurality of meshing members are provided between the disassembly plate 8 and the arc-shaped piece 5. When the arc-shaped piece 5 to be removed is determined according to the connection position of the connecting piece, the rotating ring 7 is rotated. The sleeve 6 is rotated to adjust the position of the disassembly plate 8 so that the disassembly plate 8 moves to the bottom of the corresponding arc-shaped piece 5. In order to facilitate the user to determine the specific position between the disassembly plate 8 and the arc-shaped piece 5 after the disassembly plate 8 is moved, the width of the indicator bar 13 is equal to the distance between two adjacent arc-shaped pieces 5. When the rotating ring 7 is rotated, the four indicator bars 13 are moved into the gap between the corresponding two arc-shaped pieces 5, so that the side ends of the indicator bars 13 are aligned with the side walls of the arc-shaped piece 5, thereby determining the moved position of the disassembly plate 8;

[0038] The engaging part includes a mounting block 9 and an insertion seat 11. The mounting block 9 is fixedly connected to the bottom of the arc-shaped piece 5. The bottom of the mounting block 9 is fixedly connected to two plastic arc strips 10. The insertion seat 11 is fixedly connected to the top of the disassembly plate 8. Arc-shaped notches 12 are provided on both sides of the insertion seat 11. The arc-shaped notches 12 cooperate with the plastic arc strips 10. After the disassembly plate 8 has moved, the disassembly plate 8 is moved upward, so that the insertion seat 11 will first squeeze the plastic arc strip 10 to bend upward. After the arc-shaped notch 12 area of ​​the insertion seat 11 enters between the two plastic arc strips 10, the plastic arc strip 10 flips downward and resets. The plastic arc strip 10 contacts the inner wall of the arc notch 12, so that the disassembly plate 8 and the arc piece 5 remain engaged, and continue to drive the disassembly plate 8 to move upward, so that the plastic connection point 14 and the plastic connection point 2 15 connected to the arc piece 5 are torn, so that the arc piece 5 is removed and remains on the disassembly plate 8.

[0039] The bottom bracket 1 is fixedly connected with a plurality of fixing seats 16, and a rubber insert seat 17 is provided in the fixing seat 16. The rubber insert seat 17 has two tension grooves 18 symmetrically provided. The top bracket 2 is fixedly connected with a plurality of insertion cylinders 19, and the insertion cylinders 19 correspond to the positions of the fixing seats 16. A rubber bucket-shaped sleeve 20 is provided in the insertion cylinder 19. When the bottom bracket 1, the top bracket 2 and the connecting piece need to be transported after production, the insertion cylinder 19 fixedly connected on the top bracket 2 can be inserted into the fixing seat 16 of the bottom bracket 1, and the insertion cylinder 19 fits with the inner wall of the rubber insert seat 17. By providing two tension grooves 18 on the rubber insert seat 17, it is to enable the insertion cylinder 19 to enter the rubber When the rubber insert seat 17 is inserted, the rubber insert seat 17 can be slightly deformed to adapt to the outer diameter of the insert cylinder 19, and the metal protrusion 21 on the connecting piece can also be inserted into the insert cylinder 19. The metal protrusion 21 contacts the inner wall of the rubber bucket-shaped sleeve 20. Because the rubber bucket-shaped sleeve 20 is not easy to shrink and bend, the connecting piece is kept stably placed on the top bracket 2, and multiple connecting pieces are also kept fixed on the top bracket 2. Then, during the use of the connecting piece, the connecting piece is removed from the insert cylinder 19. During the use of the top bracket 2 and the bottom bracket 1, the insert cylinder 19 can also be removed from the fixing seat 16 to complete the purpose of installing the battery between the top bracket 2 and the bottom bracket 1.

[0040] A connecting piece is provided on a battery holder with a welding short-circuit prevention function. A metal protrusion 21 is provided on the connecting piece. The metal protrusion 21 is used to electrically connect the connecting piece with other connecting cables. The metal protrusion 21 cooperates with a rubber bucket-shaped sleeve 20. The connecting piece includes an H-type connecting piece 22 and an F-type connecting piece 23. The negative electrode segments 24 of the H-type connecting piece 22 and the F-type connecting piece 23 both protrude downward. The negative electrode segment 24 is provided with an arc surface 25 that fits with the placement circular groove 24. The positive electrode segment 26 of the H-type connecting piece 22 is flush with the top of the H-type connecting piece 22, and only two negative electrode segments 24 are provided on the F-type connecting piece 23.

[0041] The working principle of the battery bracket and connecting piece with welding short-circuit protection function:

[0042] Temporarily lay the connecting piece flat on the top of the top bracket 2, determine the position of multiple connecting pieces for subsequent electrical connection with the battery, then determine the multiple arc-shaped pieces 5 that need to be disassembled in the circular groove 2 4, rotate the rotating ring 7 in the rotating sleeve 6, adjust the position of the disassembly plate 8, and move the disassembly plate 8 to the bottom of the corresponding arc-shaped piece 5. When the rotating ring 7 is rotated, the four indicator bars 13 are moved to the gap between the corresponding two arc-shaped pieces 5, so that the side ends of the indicator bars 13 are aligned with the side walls of the arc-shaped piece 5, thereby determining the movement position of the disassembly plate 8. The disassembly plate 8 is positioned and moved upward, so that the insertion seat 11 first squeezes the plastic arc strip 10 to bend upward, and after the arc notch 12 area of ​​the insertion seat 11 enters between the two plastic arc strips 10, the plastic arc strip 10 flips downward and resets, and the plastic arc strip 10 contacts the inner wall of the arc notch 12, so that the disassembly plate 8 and the arc piece 5 remain engaged, and the disassembly plate 8 continues to move upward, so that the plastic connection point 14 and the plastic connection point 2 15 that are connected to the arc piece 5 are torn, so that the arc piece 5 is removed and remains on the disassembly plate 8;

[0043] After completing the disassembly of the arc-shaped sheet 5, multiple batteries are placed between the corresponding placement circular grooves 1 3 and 2 4 between the top bracket 2 and the bottom bracket 1, and then the positive electrode segment 26 and the negative electrode segment 24 of the connecting sheet are brought into contact with the positive and negative electrodes of the battery. Then, an electric welder is used to weld the negative electrode segment 24 to the negative electrode of the motor, and the positive electrode segment 26 is separated from the negative electrode by the arc-shaped sheet 5 to avoid short circuit problems during the welding process.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
