[0001] This utility model relates to the field of battery packs, and in particular to a magnetically fixed equalization module. Background Technology

[0002] In battery management systems, the balancing module plays a crucial role, effectively balancing the state of individual cells within the battery pack and improving the overall performance and lifespan of the battery pack. Existing balancing modules are typically secured with fasteners such as screws and clips, requiring multiple tools like screwdrivers and wrenches for installation, and the complex installation process reduces efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a magnetically fixed equalization module, which solves the problems of complex installation process and the need for tools during installation of existing equalization modules.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A magnetically fixed equalization module includes an equalization module body. The equalization module body has a shell, and ear pieces are respectively provided at the four corners of the shell. Insertion sleeves are fixedly connected inside each ear piece. A sliding rod is slidably connected inside the insertion sleeve. A magnetic head is provided at one end of the sliding rod. The magnetic head is used to magnetically attract external magnetic components.

[0005] It also includes a mounting component, which includes four sleeves. The four sleeves are fixed on the end plate of the battery pack, and the position of the sleeves corresponds one-to-one with the plug-in sleeve. The sleeves are equipped with magnetic plates inside, which are adapted to the magnetic head at one end of the slide rod. After the plug-in sleeve is inserted into the sleeve, the equalization module body is fixed to the end plate of the battery pack by magnetic adsorption.

[0006] Preferably, the sleeve has a frustum-shaped interior, with the small end of the frustum-shaped inner cavity facing the opening of the sleeve. The surface of the insert sleeve has a ring array of deformation grooves, one end of which extends to the edge of the insert sleeve near the opening of the sleeve. The deformation grooves divide the part of the insert sleeve inserted into the sleeve into small blocks. The inner wall of each small block is provided with a slope, and the inclination direction of the slope is adapted to the inclination direction of the side wall of the frustum-shaped inner cavity.

[0007] Preferably, the outer side of the housing is provided with a U-shaped piece, and the other end of each slide rod is fixedly connected to the U-shaped piece. By pushing the U-shaped piece, multiple slide rods can be driven to slide simultaneously in the plug-in sleeve, thereby enabling the magnetic head and the magnetic piece to fit together quickly and improving installation efficiency.

[0008] Preferably, the plug sleeve is threaded inside the lug, and the threaded connection facilitates the replacement and maintenance of the plug sleeve.

[0009] Preferably, the surface of the magnetic accumulator is covered with a protective coating to protect it from corrosion, wear, or other external factors, thereby extending its service life.

[0010] Preferably, heat dissipation holes are provided at equal intervals on both sides of the housing. These holes can effectively dissipate the heat generated by the module during operation, preventing it from being damaged or experiencing performance degradation due to overheating.

[0011] Preferably, one end of the magnetic suction head has a rounded chamfer, which allows the magnetic suction head to more smoothly compress the inclined surface of the small piece when inserted into the sleeve.

[0012] Preferably, an adjustment ring is provided on the outer side of the plug sleeve to facilitate rotation of the plug sleeve to adjust its tightness.

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

[0014] 1. This utility model achieves rapid installation and removal of the equalization module and battery pack end plate through the magnetic adsorption effect of the magnetic head and magnetic sheet, without the need for additional tools or fasteners, thus improving installation efficiency and facilitating subsequent maintenance and replacement work.

[0015] 2. This utility model uses deformation grooves on the surface of the plug sleeve to allow the magnetic head to squeeze the inclined surfaces of each small piece under the push of the slide rod, so that each small piece deforms and disperses and is stuck in the frustum-shaped inner cavity of the sleeve, which enhances the fixing stability of the equalization module on the battery pack end plate and makes it less likely to fall off even under external force.

[0020] 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.

[0021] Please see Figures 1 to 3This embodiment provides a magnetically fixed equalization module, including an equalization module body. The equalization module body has a shell 1. The four corners of the shell 1 are provided with ear pieces 2. Each ear piece 2 is fixedly connected to a plug sleeve 3. A slide rod 4 is slidably connected inside the plug sleeve 3. One end of the slide rod 4 is provided with a magnetic head 5. The magnetic head 5 is used to magnetically attract with external magnetic components.

[0022] It also includes a mounting component, which includes a sleeve 6. There are four sleeves 6, which are fixed on the end plate of the battery pack respectively. The position of the sleeve 6 corresponds one-to-one with the insertion sleeve 3. The sleeve 6 is provided with a magnetic 7 inside. The magnetic 7 is adapted to the magnetic head 5 at one end of the slide rod 4. It is used to fix the equalization module body to the end plate of the battery pack by magnetic adsorption after the insertion sleeve 3 is inserted into the sleeve 6.

[0023] During installation, insert the four corner plug sleeves 3 of the housing 1 into the corresponding sleeves 6, push the slide rod 4 so that the magnetic head 5 at one end of the slide rod 4 fits into the magnetic piece 7 inside the sleeve 6, thereby securing the equalization module to the end plate of the battery pack through magnetic adsorption.

[0024] The sleeve 6 has a frustum-shaped interior, with the small end of the frustum-shaped inner cavity facing the opening of the sleeve 6. The surface of the insert sleeve 3 has a ring array of deformation grooves 8, one end of which extends to the edge of the insert sleeve 3 near the opening of the sleeve 6. The deformation grooves 8 divide the part of the insert sleeve 3 inserted into the sleeve 6 into small pieces. The inner wall of each small piece is provided with a slope, and the inclination direction of the slope is adapted to the inclination direction of the side wall of the frustum-shaped inner cavity.

[0025] When the slide bar 4 slides inside the plug sleeve 3, the magnetic head 5 can squeeze the inclined surfaces of each small piece, causing the small pieces to deform and disperse. In conjunction with the sleeve 6 with the frustum-shaped inner cavity, when the magnetic head 5 and the magnetic plate 7 are magnetically attracted, the deformation and dispersion of each small piece can be stuck inside the sleeve 6, enhancing the tightness of the connection between the plug sleeve 3 and the sleeve 6, thus making the equalization module more secure when fixed.

[0026] The outer side of the housing 1 is provided with a U-shaped piece 9, and the other end of the slide rod 4 is fixedly connected to the U-shaped piece 9. By pushing the U-shaped piece 9, multiple slide rods 4 can be driven to slide in the plug sleeve 3 at the same time, so that the magnetic head 5 and the magnetic piece 7 can be quickly attached, improving the installation efficiency. It also makes it easy for the operator to pull the slide rod 4 when the equalization module needs to be disassembled, so that the magnetic head 5 and the magnetic piece 7 can be separated.

[0027] The plug sleeve 3 is threaded inside the ear plate 2. The threaded connection facilitates the replacement and maintenance of the plug sleeve 3, improving the maintainability of the equalization module.

[0028] The surface of the magnetic accumulator 7 is covered with a protective coating, which can protect the magnetic accumulator 7 from corrosion, wear or other external factors and extend its service life.

[0029] Heat dissipation holes 10 are provided at equal intervals on both sides of the housing 1. The heat dissipation holes 10 can effectively dissipate the heat generated by the module during operation and prevent it from being damaged or its performance from degrading due to overheating.

[0030] The magnetic head 5 has a rounded chamfer at one end, which makes it easier and smoother to squeeze the inclined surfaces of each small piece when the magnetic head 5 is inserted into the sleeve 6, reducing resistance and friction during the installation process.

[0031] An adjusting ring 11 is provided on the outer side of the plug sleeve 3. The adjusting ring 11 can be rotated to adjust the tightness of the plug sleeve 3 inside the ear piece 2 as needed.

[0032] 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.
