Description

Technical Field

[0002] In related technologies, battery packs typically consist of a top, a housing, and a bottom module, all held together by long screws. This type of battery pack is particularly suitable for construction machinery, which often operates in dusty environments. In rainy weather or during cleaning, the top of the battery pack may come into direct contact with rainwater.

[0003] However, existing design solutions cannot completely avoid the accumulation of water on the top. The accumulated water will not only cause corrosion, but may also penetrate into the battery pack, threatening the safety of the battery. In addition, the protection against dust is insufficient, resulting in dust accumulation, which may interfere with the mechanical operation interface on the top and affect the normal operation of the equipment.

[0039] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, or indirect connections through an intermediary.

[0042] In the embodiments of the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is at a higher level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is at a lower level than the second feature. The top module and battery pack of a battery pack provided by the present invention are described below with reference to the accompanying drawings.

[0043] like Figures 1 to 7 As shown, the top module of the battery pack according to the embodiment of the first aspect of the present utility model includes a top cover 01 and a mounting base 02.

[0044] The top cover 01 is provided with a plurality of first connection areas. The first connection areas are provided with first water leakage holes 2 penetrating the top cover 01 . The top cover 01 is also provided with a first guide hole pipe 3 penetrating the top cover 01 .

[0045] The mounting base 02 is provided with a second guide hole tube 4 and several second connection areas, the second connection area is provided with a second leakage hole 6, the mounting base 02 is formed with a leakage cavity 8 and a leakage outlet 7 connected to the leakage cavity 8, and the second guide hole tube 4 and the second leakage hole 6 are both connected to the leakage cavity 8.

[0046] Among them, the top cover 01 is covered on the mounting base 02, and the first connection area and the second connection area cooperate with each other so that the first water leakage hole 2 and the second water leakage hole 6 are connected, and the first guide hole tube 3 and the second guide hole tube 4 cooperate with each other and are connected to each other.

[0047] It should be pointed out that the first connection area can be integrally formed with the top cover 01, or the first connection area can be manufactured separately from the top cover 01. In this case, the first connection area can be a structure such as the first connection plate 1, and the first connection area is installed on the top cover 01 by means of screw connection or the like.

[0048] In addition, the second connection area can be integrally formed with the top cover 01, or the second connection area can be manufactured separately from the top cover 01. In this case, the second connection area can be a structure such as a second connection plate 5, and the first connection area is installed on the top cover 01 by means of screw connection or the like.

[0049] For ease of description, the following description will be made by taking the structure in which the first connection area is the first connection plate 1 and the second connection area is the second connection plate 5 as an example without loss of generality.

[0050] As for the top module of the battery pack of the present invention, its specific structure is introduced as follows.

[0051] The top cover 01 is equipped with multiple first connecting plates 1, each of which is designed with a first drain hole 2 that penetrates the top cover 01 for draining accumulated water. In addition, the top cover 01 is also equipped with a first guide hole pipe 3 that penetrates the top cover 01 for positioning the lifting equipment to ensure accuracy during lifting.

[0052] Mounting base 02 is equipped with a second guide hole tube 4 and multiple second connecting plates 5. The second connecting plates 5 are designed with second drainage holes 6, which direct accumulated water into a pre-designed drainage cavity 8 within mounting base 02. Drainage cavity 8 is connected to drainage outlet 7, allowing accumulated water to drain through it. Furthermore, the second guide hole tube 4 is also connected to drainage cavity 8, ensuring that water entering through the guide holes in top cover 01 can also be effectively drained.

[0053] Top cover 01 covers mounting base 02. The first connecting plate 1 on top cover 01 cooperates with the second connecting plate 5 on mounting base 02, forming a communication channel between the first water leakage hole 2 and the second water leakage hole 6. Furthermore, the first guide hole tube 3 on top cover 01 and the second guide hole tube 4 on mounting base 02 also cooperate and maintain communication, ensuring that the guiding function during lifting is not affected. This also ensures that water can enter through the guide hole tube on top cover 01, be directed into the water leakage chamber 8 through the second guide hole tube 4 on mounting base 02, and ultimately be discharged through the water leakage outlet 7.

[0054] Based on the above structure, the specific operating principle and working process of the top module of the battery pack of the present invention are described as follows: When the top cover 01 is invaded by external moisture, the moisture will flow through the first leakage hole 2 to the second leakage hole 6 in the lower layer, and further enter the leakage cavity 8 of the mounting base 02. The leakage cavity 8 discharges the moisture out of the battery pack through the designed leakage outlet 7, preventing moisture from accumulating on the top of the battery pack or penetrating into the battery pack. Similarly, dust will be guided to the leakage cavity 8 through a similar path and discharged through the leakage outlet 7, preventing dust from accumulating on the top of the battery pack and ensuring the cleanliness and waterproof performance of the battery pack.

[0055] As described above, the above design ensures that the battery pack can be precisely positioned during installation via the guide holes in the top cover 01 and mounting base 02. Furthermore, the drainage holes and drainage cavity 8 designed between them can drain any water that enters, preventing rust caused by accumulated water and dust accumulation. Furthermore, the orifice plate design eliminates the need for gluing or installing sealing rings, a traditional waterproofing measure, simplifying the installation process and improving the waterproofing effect.

[0056] In related technologies, battery packs typically consist of a top, a housing, and a bottom module, all held together by long screws. This type of battery pack is particularly suitable for construction machinery, which often operates in dusty environments. In rainy weather or during cleaning, the top of the battery pack may come into direct contact with rainwater.

[0057] However, existing design solutions cannot completely avoid the accumulation of water on the top. The accumulated water will not only cause corrosion, but may also penetrate into the battery pack, threatening the safety of the battery. In addition, the protection against dust is insufficient, resulting in dust accumulation, which may interfere with the mechanical operation interface on the top and affect the normal operation of the equipment. In addition, existing waterproof designs often rely on the application of waterproof materials, which not only increases material costs, but also increases the requirements for installation processes, which is not conducive to large-scale production and rapid deployment. In contrast, this patent achieves waterproofing through structural design rather than material selection, thereby reducing the strict requirements for materials and assembly processes.

[0058] Therefore, in order to solve the technical defects existing in the above-mentioned related technologies, the present invention provides a top module of a battery pack, which has at least the following advantages compared with the related technologies.

[0059] (1) Optimization of waterproof performance: The present invention achieves waterproofing through structural design rather than relying on the selection of waterproof materials. Specifically, through the close fit between the top cover 01 and the mounting base 02 and the well-designed guide holes and drainage holes, water accumulation can be effectively avoided, thereby reducing the risk of rust caused by water accumulation.

[0060] (2) Improve drainage and dust removal efficiency: The utility model is designed with special leakage holes and leakage chamber 8, so that the accumulated water can be discharged smoothly through the leakage chamber 8 and the leakage outlet 7, and the accumulated dust can also be removed, ensuring the cleanliness of the top area of ​​the battery pack.

[0061] (3) Facilitates fully automated assembly: Since there is no need for complicated steps of gluing or installing sealing rings, the modular design of the present invention facilitates the integration of automated assembly production lines and improves production efficiency.

[0062] (4) Reduce installation complexity: Through the mutual cooperation of the guide holes and the connection areas on the top cover 01 and the mounting base 02, the utility model simplifies the installation process and reduces the requirements for installation accuracy and operator skill level.

[0063] In summary, the battery pack top module proposed in the present invention not only solves the shortcomings of the existing technology in terms of waterproofing and dustproofing through its innovative design, but also simplifies the installation process, improves assembly efficiency, and is suitable for large-scale industrial production.

[0064] like Figure 1 、 4 As shown in Figure 5, according to some embodiments of the present invention, the first connection area is a first connection plate 1, the second connection area is a second connection plate 5, a plurality of through mounting holes are provided in the top cover 01, the first connection plate 1 is fixed in the mounting hole, and a first water leakage hole 2 is formed inside the first connection plate 1 that passes through its upper and lower surfaces.

[0065] The first connecting plate 1 and the second connecting plate 5 are connected by stacking them up and down through bolts, wherein the first connecting plate 1 is provided with a plurality of first screw holes 9, and the second connecting plate 5 is provided with a plurality of second screw holes 10, and the positions of the first screw holes 9 and the second screw holes 10 correspond one to one.

[0066] In this embodiment, top cover 01 is provided with several through-holes, into which first connecting plate 1 is fixed. Furthermore, first drainage holes 2 are formed within first connecting plate 1, extending through its upper and lower surfaces. This demonstrates that first connecting plate 1 not only serves as part of the connecting structure but also as a drainage channel, allowing moisture entering top cover 01 to drain through these drainage holes into drainage cavity 8 within mounting base 02.

[0067] The first connecting plate 1 and the second connecting plate 5 are stacked and connected by bolts. Specifically, the first connecting plate 1 on the top cover 01 is bolted to the second connecting plate 5 on the mounting base 02. Specifically, the first connecting plate 1 is provided with a number of first screw holes 9, and the second connecting plate 5 is provided with a number of second screw holes 10. The positions of the first screw holes 9 and the second screw holes 10 correspond one-to-one. This design ensures a secure connection between the top cover 01 and the mounting base 02, while also ensuring that the first drainage hole 2 and the second drainage hole 6 are aligned, ensuring that water flows smoothly from the top cover 01 to the interior of the base.

[0068] This connection method not only simplifies the installation process, as it eliminates the need for additional sealing materials such as glue or seals, but also improves the waterproof performance of the entire module. Furthermore, this design facilitates fully automated assembly, as the connectors are pre-positioned and can be quickly secured with bolts.

[0069] According to some embodiments of the present invention, the first connection area is a first connection plate 1, and the upper surface of the first connection plate 1 is formed with a water guide surface inclined toward the first water leakage hole 2. For example, the upper surface of the first connection plate 1 is recessed downward to form a trumpet-shaped annular water guide surface, and the bottom of the annular water guide surface is connected to the first water leakage hole 2.

[0070] In this way, when water drops onto the first connecting plate 1, the water will be guided into the first water leakage hole 2 along the inclined water guide surface, thereby ensuring that the water flows smoothly into the first water leakage hole 2 and no residue is left on the upper surface of the first connecting plate 1, thereby improving the water leakage performance.

[0071] like Figure 1 、 4 As shown in Figures 5 and 5, according to some embodiments of the present invention, the bottom of the first connecting plate 1 is formed with one of the mating protrusions 11 and the mating grooves 12, and the top of the second connecting plate 5 is formed with the other of the mating protrusions 11 and the mating grooves 12, and the mating protrusions 11 are shaped to match the mating grooves 12.

[0072] Furthermore, a matching protrusion 11 is formed on the bottom of the first connecting plate 1 , and a matching groove 12 is formed on the top of the second connecting plate 5 .

[0073] A first sealing member is provided between the matching groove 12 and the matching protrusion 11 , or the matching groove 12 and the matching protrusion 11 are interference fit.

[0074] In the above embodiment, to achieve a better connection and seal between the top cover 01 and the mounting base 02, a mating protrusion 11 and a mating groove 12 are designed. Specifically, the bottom of the first connecting plate 1 (the connecting plate located on the top cover 01) is formed with a mating protrusion 11, while the top of the second connecting plate 5 (the connecting plate located on the mounting base 02) is formed with a corresponding mating groove 12. This design of mating protrusion 11 and mating groove 12 allows the two parts to fit tightly together, enhancing the stability of the connection.

[0075] Furthermore, while the bottom of the first connecting plate 1 is formed with a mating protrusion 11, the top of the second connecting plate 5 is designed with a mating groove 12 to ensure that the protrusion can be accurately embedded in the groove. This structure not only strengthens the connection between the top cover 01 and the mounting base 02, but also ensures a good seal between the two.

[0076] To enhance the sealing effect, a first sealing member can be provided between the mating groove 12 and the mating protrusion 11, or an interference fit can be formed between the mating groove 12 and the mating protrusion 11. An interference fit refers to the design of the dimensions between the protrusion and the groove so that they are squeezed to a certain extent during assembly, thus achieving a natural seal. This method not only effectively prevents moisture and dust from entering the battery pack, but also simplifies the assembly process and avoids the inconvenience of traditional gluing or installing sealing rings.

[0077] like Figure 1 、 6 As shown in Figures 7 and 7, according to some embodiments of the present invention, the bottom of the first guide hole tube 3 is formed with one of the small inner diameter inner sleeve portion 13 and the large inner diameter outer sleeve portion 14, and the top of the second guide hole tube 4 is formed with the other of the small inner diameter inner sleeve portion 13 and the large inner diameter outer sleeve portion 14.

[0078] Furthermore, an inner sleeve portion 13 with a small inner diameter is formed at the bottom of the first guide hole pipe 3 , and an outer sleeve portion 14 with a large inner diameter is formed at the top of the second guide hole pipe 4 .

[0079] A second sealing member is provided between the small inner diameter inner sleeve portion 13 and the large inner diameter outer sleeve portion 14 , or the small inner diameter inner sleeve portion 13 and the large inner diameter outer sleeve portion 14 are interference fit.

[0080] It is understood that when the bottom of the first guide hole tube 3 is formed with the small inner diameter inner sleeve portion 13, the top of the second guide hole tube 4 is designed with the large inner diameter outer sleeve portion 14. In this way, when the top cover 01 is connected to the mounting base 02, the small inner diameter inner sleeve portion 13 can be inserted into the large inner diameter outer sleeve portion 14 to form a tight fit.

[0081] In addition, the specific sealing measures between the first guide hole tube 3 and the second guide hole tube 4 include at least two methods. One method is to set a second sealing member between the small inner diameter inner sleeve portion 13 and the large inner diameter outer sleeve portion 14 to ensure the sealing between the two parts and prevent moisture or dust from entering; the other method is to form an interference fit between the small inner diameter inner sleeve portion 13 and the large inner diameter outer sleeve portion 14, that is, through design, the small inner diameter inner sleeve portion 13 is squeezed to a certain extent when inserted into the large inner diameter outer sleeve portion 14, thereby achieving a natural sealing effect.

[0082] This design not only strengthens the connection between the first guide hole tube 3 and the second guide hole tube 4, but also ensures the reliability and stability of the guide hole during the lifting process. At the same time, the sealing measures effectively prevent the influence of external environmental factors on the interior of the battery pack. This structural design helps to improve the overall waterproof and dustproof performance of the battery pack and simplifies the manufacturing and assembly process.

[0083] like Figure 1 and 3 As shown, according to some embodiments of the present invention, a battery hole 15 for installing a battery pack is provided in the middle position of the mounting base 02, a sealing plate 16 is provided on the side of the leakage cavity 8 facing the battery hole 15, and a plurality of leakage outlets 7 are formed on the side wall of the leakage cavity 8 away from the battery hole 15.

[0084] In this embodiment, the design of the mounting base 02 takes into account the practical requirements of waterproofing and dustproofing, and in particular, multiple measures are taken around the battery hole 15 to ensure the reliability and durability of the battery pack.

[0085] Specifically, a battery hole 15 for mounting a battery pack is provided in the middle of the mounting base 02. This hole is used to accommodate the main components of the battery pack, ensuring that the battery pack can be correctly installed and fixed on a vehicle or other application platform.

[0086] A sealing plate 16 is installed on one side of the leakage chamber 8 near the battery hole 15 to prevent moisture and dust from entering the battery pack. Sealing plate 16 effectively blocks moisture from the top and flows into the battery hole 15, protecting the battery from moisture corrosion and preventing electrical component short circuits.

[0087] A plurality of water leakage outlets 7 are provided on the side wall of the water leakage chamber 8 away from the battery hole 15. These water leakage outlets 7 are used to discharge the accumulated water and dust in the water leakage chamber 8, ensuring that the water and dust will not be retained in the battery pack, but will be guided out in time.

[0088] As shown above, through this design, mounting base 02 not only provides the necessary structural support but also ensures that the battery pack maintains good working condition under various environmental conditions. The design of sealing plate 16 effectively prevents moisture from entering battery hole 15, while leakage outlet 7 helps to quickly drain the water that enters, preventing rust and other potential damage caused by water accumulation. In addition, this design helps to improve the overall dust resistance of the battery pack, ensuring its reliable operation in dusty working environments.

[0089] In some specific embodiments of the present invention, an inclined water guiding section is formed between the water leakage chamber 8 and the water leakage outlet 7, and the inclined water guiding section is inclined from top to bottom in the direction toward the water leakage outlet 7. In this way, the inclined water guiding section can allow the accumulated water in the water leakage chamber 8 to flow smoothly to the water leakage outlet 7, thereby avoiding excessive water accumulation in the water leakage chamber 8 and increasing the risk of water ingress. At this time, the accumulated water in the water leakage chamber 8 will be guided to the water leakage outlet 7 along the inclined water guiding section and flow out, so that the accumulated water in the water leakage chamber 8 always maintains a lower water level, reducing the risk of infiltration into the battery pack.

[0090] Furthermore, an extended water outlet section is provided on the outside of the water leakage outlet 7, and the water outlet section extends from the water leakage outlet 7 in a direction away from the mounting base 02. In this way, the water flowing out of the water leakage outlet 7 will be guided to the outside away from the mounting base 02 along the water outlet section, thereby preventing the water from flowing down along the mounting base 02 and preventing the outflowing water from seeping into the battery pack inside the mounting base 02, thereby improving the waterproof performance.

[0091] like Figure 1 As shown, in some specific embodiments of the present invention, the first connection area is the first connection plate 1, the second connection area is the second connection plate 5, the number of the first connection plates 1 is four, and correspondingly, the number of the second connection plates 5 is also four; the four first connection plates 1 are respectively distributed at the four corners of the top cover 01, and the four second connection plates 5 are respectively distributed at the four corners of the mounting base 02.

[0092] There are two first guide hole tubes 3, and correspondingly, there are two second guide hole tubes 4.

[0098] like Figure 1 and Figure 3 As shown, according to some embodiments of the present invention, a snap portion 18 is further provided on the outer side of the second connecting plate 5, and the top cover 01 is snapped onto the snap portion 18. This design not only simplifies the connection process between the top cover 01 and the mounting base 02, allowing the top cover 01 to be quickly and accurately assembled, but also strengthens the bonding strength between the top cover 01 and the mounting base 02 through the snap-fit ​​fixation, further improving the waterproof and dustproof performance.

[0099] In summary, the combined use of support frame 17 and snap-on portion 18 provides a more stable connection between top cover 01 and mounting base 02, enhancing the overall module's mechanical strength while ensuring reliability and durability in harsh environments. This design facilitates modular assembly and facilitates maintenance and replacement.
