Description

Technical Field

[0001] This utility model relates to the field of battery management systems, and more particularly to a deformable balancing module. Background Technology

[0002] Balancing modules are commonly used in battery packs. By monitoring and adjusting parameters such as voltage and current of individual cells within the pack, they ensure the consistency and stability of the battery pack, thereby extending its lifespan and improving its performance. Existing balancing modules often employ fixed sizes and shapes, making them inflexible and unable to adapt to actual installation needs. In installation environments with different end plates or spacing, existing balancing modules often require complex modifications or customizations, increasing installation costs and complexity.

[0003] Existing equalization modules typically have a relatively simple structural design, making it difficult to adapt to battery packs or devices of different sizes and shapes. Utility Model Content

[0004] The purpose of this invention is to provide a deformable equalization module that solves the problems of poor installation flexibility and weak structural adaptability of existing equalization modules.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A deformable equalization module includes an inner shell and an outer shell. The outer shell is U-shaped and slidably connected to the outside of the inner shell. Both the bottom of the outer shell and the inner shell on opposite sides are fixedly connected with protrusions. Ears are symmetrically slidably connected to the outside of the protrusions. Mounting holes are opened on the surface of the ear pieces. The outer shell slides on the outside of the inner shell to increase the distance between the protrusions, which is used to adjust the distance between the ear pieces between the two protrusions.

[0006] Preferably, the outer shell has symmetrical sliding holes at the top and bottom, and the inner shell has symmetrically fixed sliders at the top and bottom. The sliders are slidably connected inside the corresponding sliding holes, so that the outer shell can slide smoothly relative to the inner shell.

[0007] Preferably, one side of the inner shell is open, and the other side of the outer shell has equidistant heat dissipation holes. The opening of the inner shell is positioned directly opposite the heat dissipation holes, which facilitates air circulation and promotes heat dissipation.

[0008] Preferably, a filter screen is provided inside the opening of the inner shell. The filter screen can effectively block external dust and impurities from entering the interior of the equalization module, keeping it clean and operating normally.

[0009] Preferably, support plates are fixedly connected to both the outer sides of the inner shell and the outer sides of the outer shell at both ends of the protrusion. The two ends of the protrusion are respectively fixedly connected to the corresponding support plates. The support plates can effectively limit the sliding range of the ear piece and prevent the ear piece from slipping off the protrusion.

[0010] Preferably, the top inner wall and the bottom inner wall of the outer shell are provided with a number of protrusions, which are symmetrically arranged on both sides of the top and bottom edges of the inner shell. The protrusions can guide the outer shell to slide correctly on the outside of the inner shell.

[0011] Preferably, the top of the inner shell has equally spaced slots, which provide additional heat dissipation channels for the equalization module and reduce its weight.

[0012] Preferably, the outer shell and the inner shell remain in close contact under normal conditions, which makes the overall structure of the balancing module compact and occupies little space.

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

[0014] 1. This utility model allows the outer shell of the module to slide relative to the inner shell, enabling the position of the lugs to be flexibly changed according to actual installation requirements. This adjustability improves the installation flexibility of the equalization module, allowing it to adapt to the thread hole spacing on different end plates and meet the needs of various installation scenarios.

[0015] 2. This utility model, through the design of a double-shell structure, makes the equalization module compact and sturdy in the undeformed state, and can resist external impact and vibration. After deformation, the gap between the inner shell opening and the outer shell increases, expanding the air circulation area and facilitating heat dissipation. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1 to 4This embodiment provides a deformable equalization module, including a housing, which includes an inner shell 1 and an outer shell 2. The inner shell 1 is provided with an equalization circuit board for realizing the equalization function. The outer shell 2 is slidably connected to the outside of the inner shell 1 in a U-shape. The bottom of the opposite side of the outer shell 2 and the inner shell 1 are fixedly connected with protrusions 3. The outer sides of the protrusions 3 are symmetrically slidably connected with lugs 4. The surface of the lugs 4 is provided with mounting holes for fixed connection with the mounting structure on the end plate of the battery pack or other components. The outer shell 2 slides on the outside of the inner shell 1 to increase the distance between the protrusions 3, which is used to adjust the distance between the lugs 4 between the two protrusions 3.

[0023] Existing equalization modules are generally installed on the end plate or other components of the battery pack using screws, which require pre-drilled threaded holes. However, the equalization module of this application can change the spacing of the lugs 4 between the two protrusions 3 by adjusting the sliding position of the outer shell 2 relative to the inner shell 1. Furthermore, the lugs 4 can slide along the protrusions 3 to adjust the spacing between the two lugs 4 on the protrusions 3, further increasing the installation flexibility and adapting to the spacing between threaded holes on different end plates. This improves the adaptability and installation convenience of the equalization module in different battery packs or installation environments.

[0024] The outer shell 2 has symmetrical sliding holes 5 at the top and bottom, and the inner shell 1 has symmetrically fixed sliders 6 at the top and bottom. The sliders 6 are slidably connected inside the corresponding sliding holes 5. Through the cooperation of the sliders 6 and the sliding holes 5, the outer shell 2 can slide smoothly relative to the inner shell 1, thereby realizing the adjustment of the distance between the protrusions 3. This sliding connection structure ensures the flexibility and stability of deformation, and also ensures that the outer shell 2 will not shift or detach when sliding.

[0025] The inner shell 1 has an opening on one side, and the outer shell 2 has heat dissipation holes 7 equidistantly spaced on one side. The opening of the inner shell 1 is directly opposite the heat dissipation holes 7. The heat inside the inner shell 1 can be directly dissipated to the external environment through the heat dissipation holes 7 on the outer shell 2, achieving effective heat dissipation. When the outer shell 2 is pulled, the gap between the opening of the inner shell 1 and the outer shell 2 will become larger and larger. This increase in gap expands the air circulation area, allowing more air to flow through the interior of the inner shell 1, thereby enhancing the heat dissipation effect and ensuring the stability and reliability of the equalization module under long-term operation.

[0026] The inner shell 1 has a filter 8 inside the opening. The filter 8 can effectively block dust, fibers and other small particles in the air from entering the inner shell 1, protect the internal components such as the equalization plate from contamination and extend the service life of the components.

[0027] Support plates 9 are fixedly connected to both ends of the protrusion 3 on the outer side of the inner shell 1 and the outer side of the outer shell 2. The two ends of the protrusion 3 are fixedly connected to the corresponding support plates 9. The support plates 9 serve as support points at the four corners of the bottom of the shell, which can ensure that the equalization module remains stable when placed or installed. The presence of the support plates 9 can also effectively limit the sliding range of the ear piece 4 and prevent the ear piece 4 from slipping off the protrusion 3.

[0028] The top and bottom inner walls of the outer shell 2 are provided with several protrusions 10. The protrusions 10 are symmetrically arranged on both sides of the top and bottom of the inner shell 1. In order to limit the offset and shaking of the outer shell 2 during the sliding process, when the outer shell 2 slides relative to the inner shell 1, the protrusions 10 will contact the side of the inner shell 1. Through friction and geometric constraint, the sliding of the outer shell 2 is made more stable and controllable.

[0029] The inner shell 1 has equidistant slots 11 on its top. In the normal state, that is, when the outer shell 2 is not pulled or adjusted, the slots 11 are completely covered by the outer shell 2. By pulling the outer shell 2, the slots 11 will gradually be exposed. The exposed slots 11 can be used to increase airflow and improve heat dissipation efficiency.

[0030] The outer shell 2 and the inner shell 1 remain in close contact under normal conditions, thus forming a double-layer structure in the undeformed state. This double-layer structure enhances the overall structural strength of the equalization module, making it more robust and durable, and able to resist external impacts and vibrations. Furthermore, when undeformed, the overall size is compact, occupying little installation space, making it easier to install the equalization module in battery packs or devices with limited space, thus improving the flexibility and convenience of installation.

[0031] When the outer shell 2 is pulled to deform, the position of the lugs 4 on the protrusion 3 is changed, thereby adjusting the spacing between the lugs 4. This allows the equalization module to adapt to the installation requirements of different end plates, improving its adaptability and versatility. Furthermore, after the outer shell 2 is pulled to deform, the gap between the opening of the inner shell 1 and the outer shell 2 increases, expanding the airflow area and allowing more air to flow through the interior of the inner shell 1, carrying away more heat and thus enhancing the heat dissipation effect.

[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.
