Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, and in particular to a vacuum cleaner lithium battery pack with efficient heat dissipation and shock absorption functions. Background Technology

[0002] As the core power source for cordless vacuum cleaners, lithium battery packs have seen continuous optimization in structure and performance design in recent years, driven by the increasing popularity of portable cleaning devices and users' growing demands for longer battery life, charging efficiency, and safety. Traditional vacuum cleaner battery packs, due to their compact size and high power density, tend to generate a lot of heat during operation. Poor heat dissipation can lead to decreased battery performance, shortened cycle life, and even safety hazards.

[0003] The heat generated by the lithium battery pack of the vacuum cleaner during operation cannot be dissipated in a timely and effective manner, which can cause the battery temperature to rise and easily lead to overheating, swelling or even safety accidents. When the vacuum cleaner is subjected to impact or vibration during movement or use, the internal components and cells of the battery pack, which lack shock absorption protection, are prone to loosening, misalignment or even damage. Utility Model Content

[0004] The purpose of this utility model is to provide a vacuum cleaner lithium battery pack with efficient heat dissipation and shock absorption functions. Several heat dissipation fins fixedly connected to the lower surface of the support base can significantly increase the heat dissipation area, effectively conducting and dissipating the heat generated by the battery pack during operation. The limiting blocks set on both sides of the inner wall of the protective shell, together with the slidingly connected limiting abutment pad and the abutment block below it, work together to provide multi-directional limiting support and buffer shock absorption for the battery pack, effectively absorbing the impact and vibration during operation and preventing damage to the battery pack.

[0005] To achieve the above objectives, a vacuum cleaner lithium battery pack with efficient heat dissipation and shock absorption functions is provided, comprising: a support base, a plurality of heat dissipation fins fixedly connected to the lower surface of the support base, a thermally conductive contact pad fixedly connected to the upper surface of the support base, the upper surface of the thermally conductive contact pad abutting against a battery pack, a protective shell fixedly connected to the support base by a first positioning bolt, two limiting blocks fixedly connected to the left and right sides of the inner wall of the protective shell, a limiting contact pad slidably connected between the two limiting blocks, a contact block abutting against the lower surface of the limiting contact pad, and a limiting plate fixedly connected to the protective shell by a second positioning bolt. This effectively improves the heat dissipation efficiency and shock absorption protection capability of the battery pack, ensuring safe and reliable operation.

[0006] According to the aforementioned vacuum cleaner lithium battery pack with efficient heat dissipation and shock absorption functions, the sidewall of the contact block is fixedly connected to the protective shell, and the sidewall of the limiting contact pad abuts against the battery pack. This enhances the structural stability and impact resistance of the battery pack, improving its overall service life and safety.

[0007] According to the aforementioned vacuum cleaner lithium battery pack with efficient heat dissipation and shock absorption functions, the size of the limiting plate is adapted to the size of the protective shell, and the limiting plate abuts against the upper surface of the battery pack. This achieves vertical positioning and protection of the battery pack, preventing displacement or loosening during operation.

[0008] According to the aforementioned vacuum cleaner lithium battery pack with efficient heat dissipation and shock absorption functions, the number of first positioning bolts is four, and the four first positioning bolts are symmetrically arranged on the front and rear sides of the protective shell. This improves the balance and robustness of the assembly structure, ensuring a more stable and reliable overall connection of the battery pack.

[0009] According to the aforementioned vacuum cleaner lithium battery pack with efficient heat dissipation and shock absorption functions, the first positioning bolt extends into the interior of the support base, and the abutment block is located between two limiting blocks. This optimizes the coordinated operation of the components within the battery pack, further enhancing the shock absorption and limiting effects.

[0010] The above-mentioned solution has the following beneficial effects:

[0011] This utility model comprises a thermally conductive contact pad, a battery pack, a support base, a first positioning bolt, a protective shell, a limiting block, a limiting contact pad, a contact block, a second positioning bolt, and a limiting plate. Several heat dissipation fins fixedly connected to the lower surface of the support base significantly increase the heat dissipation area, effectively conducting and dissipating the heat generated by the battery pack during operation. The limiting blocks on both sides of the inner wall of the protective shell, together with the slidingly connected limiting contact pad and the contact block below it, provide multi-directional limiting support and cushioning for the battery pack, effectively absorbing impacts and vibrations during operation and preventing damage to the battery pack.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-4 This utility model discloses a vacuum cleaner lithium battery pack with efficient heat dissipation and shock absorption functions, comprising: a support base 1, with a plurality of heat dissipation fins 2 fixedly connected to the lower surface of the support base 1 to enhance the heat dissipation effect of the support base 1, thereby effectively reducing the heat accumulation generated by the battery pack 4 during operation and improving the overall thermal management performance; a thermally conductive contact pad 8 fixedly connected to the upper surface of the support base 1, the thermally conductive contact pad 8 being tightly bonded to the support base 1, which facilitates the efficient conduction of the heat generated by the battery pack 4 to the support base 1 and its heat dissipation fins 2, accelerating heat diffusion; the upper surface of the thermally conductive contact pad 8 abuts against the battery pack 4, this close fit design ensures that the heat of the battery pack 4 can be directly transferred to the thermally conductive contact pad 8, achieving efficient thermal coupling between the battery pack 4 and the heat dissipation system; and a protective shell 3 is fixedly connected to the support base 1 by a first positioning bolt 5, the first positioning bolt 5 ensuring not only the support base 1 and the protective shell are properly connected. The robust connection of the protective shell 3 provides crucial support for the stability and protection of the internal structure. Two limiting blocks 10 are fixedly connected to the left and right sides of the inner wall of the protective shell 3. The two limiting blocks 10 are located on both sides of the protective shell 3, forming a defined space, providing guidance and positional constraint for the sliding of the limiting contact pad 9. The limiting contact pad 9 is slidably connected between the two limiting blocks 10. The limiting contact pad 9 can slide freely between the limiting blocks 10, playing a role in buffering and absorbing vibration, thereby effectively protecting the battery pack 4 from external impact. The lower surface of the limiting contact pad 9 abuts against the contact block 11. The contact block 11 is located below the limiting contact pad 9, forming a reliable support interface, further improving the shock absorption and limiting effect of the limiting contact pad 9. The protective shell 3 is fixedly connected to the limiting plate 6 by the second positioning bolt 7. The second positioning bolt 7 ensures that the limiting plate 6 is firmly connected to the protective shell 3, providing additional limiting and protection for the upper surface of the battery pack 4.

[0022] The sidewall of the contact block 11 is fixedly connected to the protective shell 3. This fixing method ensures that the contact block 11 can distribute the pressure to the protective shell 3 when subjected to external force, thereby improving the impact resistance of the overall structure. The sidewall of the limiting contact pad 9 abuts against the battery pack 4. The limiting contact pad 9 fits against the battery pack 4 through its sidewall, thereby achieving lateral limiting and buffer protection for the battery pack 4. The size of the limiting plate 6 is adapted to the size of the protective shell 3. The size matching ensures that the limiting plate 6 can fully cover the upper surface of the battery pack 4, forming a sealed protective space together with the protective shell 3. The limiting plate 6 abuts against the upper surface of the battery pack 4. The limiting plate 6 is in direct contact with the upper surface of the battery pack 4, providing protection for the battery pack 4. Vertical positioning and support prevent displacement during operation. There are four first positioning bolts 5, which are symmetrically arranged on the front and rear sides of the protective shell 3. This symmetrical distribution structure improves the stability of the entire battery pack assembly and prevents loosening or deformation caused by uneven force. The first positioning bolts 5 extend into the interior of the support base 1. This structure strengthens the overall connection between the support base 1 and the protective shell 3, providing a solid foundation for the safe operation of the battery pack. The contact block 11 is located between the two limiting blocks 10. The arrangement of the contact block 11 further optimizes the limiting structure, enabling the shock absorption and limiting functions to work together and improving the safety protection capability of the battery pack.

[0023] Working principle: First, several heat dissipation fins 2 are fixedly connected to the lower surface of the support base 1, ensuring that they are fully exposed to the air to facilitate heat dissipation. A thermally conductive contact pad 8 is fixedly connected to the upper surface of the support base 1, providing a basis for heat conduction of the subsequent battery pack 4. The battery pack 4 is accurately placed above the thermally conductive contact pad 8, ensuring full contact with the pad for efficient heat transfer. The protective shell 3 is aligned with the support base 1, and four symmetrically distributed first positioning bolts 5 are used to firmly fix the protective shell 3 to the support base 1, ensuring the overall structure is stable. Two limiting blocks 10 are fixed to the left and right sides of the inner wall of the protective shell 3, and a limiting contact pad 9 is slidably installed between the two limiting blocks 10. The lower surface of the pad is brought into contact with the contact block 11; at the same time, the side wall of the contact block 11 is fixed to the protective shell 3 to form a stable shock-absorbing structure, ensuring that the side wall of the limiting contact pad 9 is in close contact with the battery pack 4, achieving lateral limiting and buffering, and protecting the battery pack 4 from movement and vibration. The limiting plate 6 is placed on the upper surface of the battery pack 4, making its size compatible with the protective shell 3. The limiting plate 6 is fixed to the protective shell 3 by the second positioning bolt 7, achieving vertical limiting and overall protection of the battery pack 4. It is confirmed that all bolts are tightened, all components are securely connected, the limiting and shock-absorbing system effectively fits the battery pack 4, and the heat dissipation system is unobstructed, ensuring that the battery pack has good heat dissipation and shock absorption performance during operation.
