Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to an adjustable equalization module mounting structure. Background Technology

[0002] The balancing module effectively balances the charge of individual cells in a battery pack, improving the overall performance and lifespan of the battery pack. Existing balancing modules typically require multiple fixing methods such as screws and clips to be installed on the battery pack, a cumbersome and time-consuming process that also requires additional tools, increasing installation difficulty and cost.

[0003] Once the equalization module is installed, its position is often difficult to adjust. Because the battery pack assembly process may require adjustments to the equalization module's position based on actual conditions, the existing installation structure cannot meet this requirement, thus limiting the flexibility of the equalization module's use. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable equalizer module installation structure, which solves the problems of complex installation process and inconvenient position adjustment of existing equalizer modules.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An adjustable equalization module installation structure includes connecting pieces, two of which are provided. Inner rods are slidably inserted into both ends of the connecting pieces, and sleeves are rotatably connected to the outer sides of the inner rods. The outer sides of the sleeves have a helical groove array in an annular pattern. A torsion spring is sleeved on the outer side of the inner rods. The sleeves and inner rods are elastically connected by the torsion springs. The circuit board of the equalization module has insertion holes at the four corners that match the shape of the sleeves. The inner walls of the insertion holes have a helical groove array in an annular pattern. When the sleeve is inserted into the insertion hole, the protrusions slide along the helical grooves, thereby guiding the sleeve to rotate.

[0006] Preferably, the bottom of the two connecting pieces is symmetrically provided with slide bars, and the bottom end of the inner rod is fixedly connected to the corresponding slide bar. The connecting pieces and slide bars form a frame structure to ensure that the plug holes on the circuit board can be aligned with each sleeve during installation.

[0007] Preferably, an end plate is provided below the circuit board, and slide rails are symmetrically opened on the surface of the end plate. Slide bars are slidably connected to the corresponding slide rails, so that the connecting piece and the equalization module fixed on it can slide freely along the slide rails on the end plate, realizing flexible adjustment of the installation position of the equalization module.

[0008] Preferably, a collar is fitted on the outer side of the inner rod, and a telescopic spring is provided between the collar and the corresponding connecting piece. The collar and the connecting piece are elastically connected by the telescopic spring. The collar not only provides additional support for the circuit board, but also provides shock absorption protection for the circuit board through the elastic action of the telescopic spring.

[0009] Preferably, the end plate surface is symmetrically provided with toothed grooves, and the bottom of the connecting piece is symmetrically provided with toothed strips. When the connecting piece is attached to the end plate, the toothed strips and toothed grooves mesh with each other, so that there is a jerky feeling when dragging the connecting piece.

[0010] Preferably, the cross-section of the slider is T-shaped, and the shape of the slide rail matches the slider, making the slider slide more stably in the slide rail and preventing the slider from shaking or coming off during the sliding process.

[0011] Preferably, fixing holes are symmetrically provided on both sides of the end plate, so that the end plate can be fixedly connected to other parts of the battery pack through the fixing holes.

[0012] Preferably, the toothed strip and toothed groove have triangular tooth shapes. The triangular tooth shape makes the toothed strip and toothed groove more tightly engaged during meshing, which improves the stability of the connecting piece during sliding.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. This utility model, through the design of the sleeve and the circuit board insertion hole, combined with the guidance of the protrusion and spiral groove, allows the sleeve to be easily inserted into and fixed to the circuit board, realizing the rapid installation of the equalization module. No additional tools or complicated operating steps are required during the installation process, thus improving the installation efficiency.

[0015] 2. This utility model provides additional support and shock absorption protection for the circuit board through the design of the collar and telescopic spring, ensuring the stability of the equalization module during battery pack operation. The meshing design of the toothed strip and toothed groove increases the operating feel during adjustment and, to a certain extent, prevents the equalization module from shifting without human intervention, thus improving the reliability of the installation structure.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1 to 7 This embodiment provides an adjustable equalization module installation structure, including a connecting piece 1. Two connecting pieces 1 are provided. Inner rods 2 are slidably inserted into both ends of the connecting piece 1. Sleeves 3 are rotatably connected to the outer side of the inner rods 2. The outer side of the sleeves 3 has a spiral groove array in an annular pattern. A torsion spring 4 is sleeved on the outer side of the inner rods 2. The sleeves 3 and the inner rods 2 are elastically connected by the torsion spring 4. The circuit board 5 of the equalization module has insertion holes at the four corners that match the shape of the sleeves 3. The inner wall of the insertion holes has a protrusion array in an annular pattern. When the sleeves 3 are inserted into the insertion holes, the protrusions slide along the spiral grooves, thereby guiding the sleeves 3 to rotate.

[0026] During installation, first, the circuit board 5 of the equalization module is aligned with the predetermined position on the battery pack end plate 7. At this time, the sleeve 3 is inserted into the insertion holes at the four corners of the circuit board 5. The spiral groove on the outside of the sleeve 3 cooperates with the protrusion on the inner wall of the insertion hole. When the sleeve 3 is inserted, the protrusion slides along the spiral groove. This sliding action guides the sleeve 3 to rotate.

[0027] As the sleeve 3 rotates, the torsion spring 4 on its outer side deforms and stores energy. The elastic effect of the torsion spring 4 causes the sleeve 3 to be subjected to a rotational force during rotation. When the sleeve 3 continues to be inserted and bends past the edge of the insertion hole, the protrusion separates from the spiral groove. At this time, the torsion spring 4 releases the stored energy, causing the sleeve 3 to rotate back to its original position.

[0028] After resetting, the spiral groove on the outer side of the sleeve 3 is offset from the protrusion on the inner wall of the insertion hole, forming a snap-fit ​​connection. This connection method prevents the sleeve 3 from being removed from the insertion hole, thus firmly locking the four corners of the circuit board 5 of the equalization module onto the corresponding inner rod 2, achieving the fixed installation of the equalization module.

[0029] Two connecting pieces 1 are symmetrically provided with slide bars 6 at their bottoms. The bottom end of the inner rod 2 is fixedly connected to the corresponding slide bar 6. The connecting pieces 1 and slide bars 6 form a frame structure to ensure that the plug holes on the circuit board 5 can be aligned with each sleeve 3 during installation.

[0030] The circuit board 5 is provided with an end plate 7 below it. The surface of the end plate 7 is symmetrically provided with slide rails 8. Slide bars 6 are slidably connected to the corresponding slide rails 8. The slide bars 6 can slide freely in the slide rails 8 of the end plate 7, so that the connecting piece 1 and the equalization module fixed thereon can move along the direction of the slide rails 8, and the position of the equalization module can be adjusted according to actual needs.

[0031] The inner rod 2 is fitted with a collar 9 on the outside. A telescopic spring 10 is provided between the collar 9 and the corresponding connecting piece 1. The collar 9 and the connecting piece 1 are elastically connected by the telescopic spring 10. The collar 9 can support the circuit board 5 and also play a role in shock absorption and protection during the operation of the battery pack.

[0032] The end plate 7 has symmetrical toothed grooves 11 on its surface and toothed strips 12 symmetrically on its bottom. When the connecting piece 1 is attached to the end plate 7, the toothed strips 12 and toothed grooves 11 mesh with each other, so that there is a jerky feeling when dragging the connecting piece 1, which increases the feel of operation during the adjustment process and prevents the equalization module from shifting without human intervention to a certain extent.

[0033] The cross-section of the slider 6 is T-shaped, and the shape of the slide rail 8 matches that of the slider 6, making the sliding of the slider 6 within the slide rail 8 more stable and preventing the slider 6 from shaking or coming off during the sliding process.

[0034] The end plate 7 has symmetrical fixing holes 13 on both sides, so that the end plate 7 can be fixedly connected to other parts of the battery pack through the fixing holes 13.

[0035] The toothed strip 12 and toothed groove 11 have triangular tooth shapes. The triangular tooth shape makes the toothed strip 12 and toothed groove 11 more tightly engaged when meshing, which improves the stability of the connecting piece 1 during the sliding process.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
