Description

Technical Field

[0001] This invention belongs to the field of energy storage battery technology, and particularly relates to a household energy storage battery enclosure. Background Technology

[0002] A home energy storage battery management system (BMS) is the core component of a home energy storage system, responsible for ensuring the safe, efficient, and long-life operation of the battery pack. Through proper selection and BMS optimization, home energy storage systems can significantly improve self-consumption rates (up to 80% or more) while extending battery life to over 10 years. Home energy storage devices include battery energy storage systems: their core is a rechargeable battery, typically a lithium-ion or lead-acid battery, which stores and releases energy through charging and discharging cycles. Because the motherboard and battery generate significant heat during charging and discharging, failure to dissipate heat promptly can affect the normal operation of the device.

[0003] The existing methods mainly involve directly mounting the fan on the equipment housing, and adding a protective ventilation mesh at the fan location and another protective ventilation mesh on the side wall of the housing. This usually involves drawing the heat inside the equipment out of the housing by air extraction to achieve the purpose of heat dissipation.

[0004] However, as the fan continues to circulate air for heat dissipation, dust will accumulate on the heat dissipation structure of the equipment casing to varying degrees. This will affect its heat conduction and heat dissipation performance, and the battery box (including the fan and external heat dissipation components such as the vent mesh) needs to be completely disassembled before cleaning can be carried out; therefore, the cleaning operation is complicated and inefficient.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: 1) This invention enables online, non-disassembly-free cleaning of heat-conducting fins, significantly improving maintenance convenience and efficiency: By mounting a lateral drive component on the housing and connecting it to the brushing body, the brushing body can directly brush away dust from the surface of the heat-conducting fins under the drive of the lateral drive component. This overcomes the drawback of existing technologies that require disassembling the battery pack or the entire housing to clean the heat dissipation structure.

[0017] 2) The integrated design of heat dissipation and maintenance has been optimized, achieving a balance between efficient thermal management and convenient maintenance within a compact space: This invention integrates the battery pack's support, heat conduction, and extended heat dissipation surface (fins) into one unit, making the heat dissipation structure more compact and directly providing the possible space (inner cavity) and the object of operation (heat-conducting fins) for the cleaning mechanism. Thus, within a limited space, not only is effective contact heat conduction and extended heat dissipation of the battery pack achieved through the supporting heat-conducting plate and heat-conducting fins, but the integrated cleaning mechanism also enables convenient maintenance of this key heat dissipation component, achieving a balance between heat dissipation performance and maintainability. This integrated design avoids the problem of adding complex disassembly structures for individual maintenance of heat dissipation components, simplifying the overall structure.

[0026] The following is in conjunction with the appendix Figures 1-6 The present invention will be described in further detail, but this is not intended to limit the invention.

[0027] like Figures 1 to 3 As shown, in one embodiment of the present invention, the home energy storage battery box includes a housing 100, a washing mechanism 200, and a supporting heat-conducting component 300. The supporting heat-conducting component 300 includes a supporting heat-conducting plate 310 and at least one heat-conducting fin 320 connected to one side surface of the supporting heat-conducting plate 310. The supporting heat-conducting plate 310 is connected to the interior of the housing 100, and at least two placement cavities 101 are provided between the other side surface of the supporting heat-conducting plate 310 away from the heat-conducting fin 320 and the housing 100. The placement cavities 101 are used for... A battery pack 400 is placed therein; a supporting contact surface 301 is provided on the other side of the supporting heat-conducting plate 310 away from the heat-conducting fins 320; the supporting contact surface 301 is used to abut against the battery pack 400; the brushing mechanism 200 includes a transverse drive component 204 and a brushing body 210; the transverse drive component 204 is disposed on the receiving body 100; and the transverse drive component 204 is driven to one side end of the brushing body 210 so that the other side end of the brushing body 210 extends into the placement cavity 101 and contacts the side surface of the heat-conducting fins 320.

[0028] Compared with the prior art, the present invention has at least the following beneficial effects: 1) This invention enables online, non-disassembly-free cleaning of heat-conducting fins, significantly improving maintenance convenience and efficiency: By mounting a lateral drive component on the housing and connecting it to the brushing body, the brushing body can directly brush away dust from the surface of the heat-conducting fins under the drive of the lateral drive component. This overcomes the drawback of existing technologies that require disassembling the battery pack or the entire housing to clean the heat dissipation structure. This achieves online cleaning of dust from the heat-conducting fins without disassembling the supporting heat-conducting components or even the entire battery housing, significantly simplifying the cleaning process and improving the convenience and efficiency of maintenance operations. This effectively solves the problems of complex and inefficient cleaning operations in existing technologies.

[0029] 2) The integrated design of heat dissipation and maintenance has been optimized, achieving a balance between efficient thermal management and convenient maintenance within a compact space: This invention integrates the battery pack's support, heat conduction, and extended heat dissipation surface (fins) into one unit, making the heat dissipation structure more compact and directly providing the possible space (inner cavity) and the object of operation (heat-conducting fins) for the cleaning mechanism. Thus, within a limited space, not only is effective contact heat conduction and extended heat dissipation of the battery pack achieved through the supporting heat-conducting plate and heat-conducting fins, but the integrated cleaning mechanism also enables convenient maintenance of this key heat dissipation component, achieving a balance between heat dissipation performance and maintainability. This integrated design avoids the problem of adding complex disassembly structures for individual maintenance of heat dissipation components, simplifying the overall structure.

[0030] In some implementation methods, such as Figure 1 As shown, the container 100 is provided with a cabinet door 102; the cabinet door 102 is used to control the opening or closing of the placement cavity 101; thereby realizing the convenience of disassembling the battery pack 400 and the stability of the limit position.

[0031] Specifically, in some implementations, such as Figure 1 As shown, the inner bottom of the container 100 is provided with at least one first heat dissipation hole 110. One end of the first heat dissipation hole 110 is connected to the placement cavity 101; the other end of the first heat dissipation hole 110 is connected to the outside of the container 100; the top of the container 100 is provided with a gas conveying component 120; the output end of the gas conveying component 120 is connected to the placement cavity 101; the input end of the gas conveying component 120 is connected to the outside of the container 100. In some embodiments, such as... Figure 1 and 2As shown, the container 100 is provided with a heat dissipation mesh plate 111; the first heat dissipation hole 110 is set through the thickness of the heat dissipation mesh plate 111; and the heat dissipation mesh plate 111 is connected to the bottom of the container 100 (by screws or welding, etc.). The gas conveying component 120 includes a conveying fan 121; the air outlet path of the conveying fan 121 is set towards the placement cavity 101. Furthermore, both the output end and the input end of the conveying fan 121 are provided with protective nets to prevent large foreign objects such as animals from entering. This structure, through the blowing action of the conveying fan 121, enables the heat dissipation gas to be discharged from top to bottom to the first heat dissipation hole 110, thereby improving the heat dissipation effect. Of course, the conveying fan 121 can be selected according to the corresponding product model and size according to conventional technical means in the art, and will not be limited here.

[0032] Specifically, in some implementation methods, such as Figure 1 and 2 As shown in Figure 6, the number of heat-conducting fins 320 is at least two, and a heat-conducting channel 301 is provided between two adjacent heat-conducting fins 320 and the supporting heat-conducting plate 310; and the housing 100 is provided with at least one brushing through hole 103; the brushing body 210 passes through the brushing through hole 103 and extends into the heat-conducting channel 301. This structure improves the smoothness and efficiency of brushing by having the brushing body 210 pass through the brushing through hole 103 from the side and outside under the action of lateral movement, and brushing the two opposing surfaces of two adjacent heat-conducting fins 320 back and forth inside the heat-conducting channel 301.

[0033] Specifically, in some implementation methods, such as Figure 1 and 2 As shown, an assembly gap 104 is provided between the end of the heat-conducting fin 320 facing the brushing through hole 103 and the housing 100; an installation gap 105 is provided between the end of the heat-conducting fin 320 away from the supporting heat-conducting plate 310 and the battery pack 400. This structure, under the blowing action of the conveying fan 121, forms a heat dissipation path A, allowing airflow heat dissipation through the inlet of the placement cavity 101 while the brushing mechanism 210 is performing online cleaning operations; and through the assembly gap 104 and the installation gap 105, a heat dissipation path B is formed, further enabling airflow heat dissipation through the inlet of the placement cavity 101 while the brushing mechanism 210 is performing online cleaning operations, avoiding the need for disassembly for cleaning; thereby increasing the coverage of the heat dissipation airflow and improving the heat dissipation speed and efficiency.

[0034] Specifically, in some implementations, such as Figures 2 to 4As shown, the brushing body 210 includes a brushing spindle 211 and brush bristles 212 connected to the side surface of the brushing spindle 211; one end of the brushing spindle 211 is connected to the movable end of the transverse drive component 204; the brush bristles 212 are arranged in contact with the side surface of the heat-conducting fins 320. In use, as the brushing spindle 211 is pushed toward the placement cavity 101, the softness of the brush bristles 212 causes partial bending contact, creating a gap space that allows gas to pass through. This allows the inner surface of the heat-conducting fins 320 to be brushed while ensuring its heat dissipation function is carried out in an orderly manner. Thus, while ensuring the heat dissipation function, it also saves the assembly space of the battery pack 400 and can clean dust online, overcoming the problem that some existing technologies require complete disassembly for cleaning.

[0035] Specifically, in some implementations, such as Figure 1 and 3 As shown, the brushing mechanism 210 also includes a protective housing 220; the transverse drive component 204 includes a push drive source 230, a folding connector 240, and a mounting plate 250; the protective housing 220 is connected to the back of the housing 100, and the protective housing 220 has a mounting cavity 210 inside; the mounting cavity 210 (through the brushing through hole 103) is connected to the placement cavity 101; the mounting end of the push drive source 230 is connected to the inside of the mounting cavity 210; the movable end of the push drive source 230 is connected to the folding connector 240; one side of the folding connector 240 is movably connected to the mounting plate 250; one side of the brushing body 210 (the middle brushing spindle 211) is connected to the mounting plate 250. This structure, driven by the driving source 230, folds the connecting piece 240, effectively reducing the overall space occupied by the driving components and ensuring smooth operation of the mounting plate 250 and the brush body 210 during the reciprocating brushing process; thus, it reduces the overall space occupied by the housing. In some embodiments, such as... Figure 3 and 4 As shown, a guide rod 202 is provided inside the protective housing 220; a limiting protrusion 251 is provided on one side of the mounting plate 250; the limiting protrusion 251 is sleeved on the outer surface of the guide rod 202 to further ensure the stability of the lateral pushing.

[0036] Specifically, in some implementations, such as Figure 3As shown, the protective housing 220 has at least one second heat dissipation hole 203 on both the left and right sides; one side of the second heat dissipation hole 203 is connected to the mounting cavity 210; the other side of the second heat dissipation hole 203 is connected to the outside of the protective housing 220; due to the softness of the bristles 212, partial bending contact is achieved to create a gap space that allows gas to pass through. This structure, through the connectivity of the second heat dissipation hole 203, the mounting cavity 210, the brush cleaning through hole 103, and the placement cavity 101, increases the heat dissipation path, so that the heat exchange airflow generated by the conveying fan 121 can be discharged from the second heat dissipation hole 203, thereby improving the heat dissipation efficiency and effect.

[0037] Specifically, in some implementations, such as Figure 3 and 4 As shown, the drive source 230 includes a drive motor 231, a rotating screw 232, and a slide 233. The drive motor 231 is connected to the interior of the mounting cavity 210. One end of the rotating screw 232 is connected to the drive motor 231. The other end of the rotating screw 232 extends along the height direction of the mounting cavity 210 and is movably connected to the protective housing 220 (via a rotating bearing). The interior of the slide 233 is slidably connected to the outer surface of the rotating screw 232 (via a threaded surface). The slide 233 is connected to the folding connector 240. The drive motor 231 can be a forward and reverse rotating drive motor to drive the folding connector 240 to fold and swing during the up and down sliding of the slide 233. This causes the brush body 210 to pass through the brushing through hole 103 and brush the two opposite surfaces of the two adjacent heat-conducting fins 320 back and forth inside the heat-conducting channel 301, thereby improving the smoothness and efficiency of brushing. Of course, the drive motor 231 can be selected according to the corresponding product model and size according to conventional technical means in this field, and no specific limitation will be made here.

[0038] Specifically, in some implementations, such as Figure 3 and 4As shown, the folding connector 240 includes a first swing connecting rod 241 and a second swing connecting rod 242; one end of the first swing connecting rod 241 (via a first movable pin) is swing-connected to the inner wall of the protective housing 220; the other end of the first swing connecting rod 241 (via a second movable pin) is swing-connected to one end of the second swing connecting rod 242; the other end of the second swing connecting rod 242 (via a third movable pin) is swing-connected to the mounting plate 250; and the slide 233 is connected to the second movable pin between the first swing connecting rod 241 and the second swing connecting rod 242 via a connecting rod; so as to realize the pull-back driving action of retraction and folding and the pushing action of unfolding, thereby causing the brush body 210 to pass through the brushing through hole 103 and brush back and forth in the heat conduction channel 301 to brush the two opposite surfaces of the two adjacent heat conduction fins 320; thus improving the smoothness and efficiency of brushing.

[0039] Specifically, in some implementations, such as Figure 1 , 2 As shown in Figure 5, the supporting heat-conducting plate 310 includes a first heat-conducting section 311 and a second heat-conducting section 312 connected to one side of the first heat-conducting section 311; heat-conducting fins 320 are connected to the bottom surface of the first heat-conducting section 311; and the second heat-conducting section 312 is provided with at least one guide hole 313; the guide hole 313 is arranged through the thickness direction of the second heat-conducting section 312. This structure achieves contact heat conduction and heat dissipation through the second heat-conducting section 312 and its heat-conducting fins 320, combined with the heat-carrying effect of the fluid in the second heat-conducting section 312 and its guide hole 313, to achieve multiple heat dissipation effects, thereby improving heat dissipation efficiency and effect. The top of the first heat-conducting section 311 is detachably connected to the inner back of the housing 100 by a first fixing screw; the bottom of the second heat-conducting section 312 is detachably connected to the inner end of the housing 100 by a second fixing screw, so as to improve the convenience of disassembly and maintenance while simultaneously cleaning dust online.

[0040] Specifically, in some embodiments, the thermal conductivity of the first heat-conducting section 311 is lower than that of the second heat-conducting section 312; and the projection of the battery pack 400 toward the second heat-conducting section 312 covers the portion of the guide hole 313. The first heat-conducting section 311 is made of copper or aluminum; the second heat-conducting section 312 is made of iron or stainless steel. This structure improves heat dissipation speed by utilizing the externally better thermal conductivity of the second heat-conducting section 312 under the blowing action of the conveying fan 121; then, under the action of the temperature difference between the first and second heat-conducting sections 311, some heat from the first heat-conducting section 311 can be transferred outward to the second heat-conducting section 312, thereby accelerating heat dissipation while simultaneously cleaning dust; furthermore, the heat dissipation speed and efficiency are further improved by the multiple guide holes 313 not covered by the battery pack 400 and the airflow from the conveying fan 121.

[0041] Specifically, in some implementations, such as Figure 5 and 6 As shown, the heat-conducting fin 320 has at least one heat-conducting protrusion 321 on one side of the heat-conducting channel 301; on two adjacent heat-conducting fins 320, two different adjacent heat-conducting protrusions 321 are staggered to form a curved and irregularly shaped heat-conducting channel 301 to increase the amount of heat transfer and increase the gap space between the heat-conducting fin and the bristles, thereby ensuring that the heat dissipation effect is carried out in an orderly manner.

[0042] Specifically, in some implementations, such as Figure 3 and 6 As shown, on two adjacent heat-conducting fins 320, the relationship between the distance L1 of the two different adjacent heat-conducting protrusions 321, the outer diameter L3 of the brush body 210 and the outer diameter L2 of the brush spindle 211 satisfies: L2≤L1=(7 / 6~6 / 5)*L3. Through reasonable size relationship, the smooth passage of the brush spindle 211 and the bristles 212 is ensured, and the gap space between the heat-conducting fins 320 and the bristles is ensured, thereby improving the cleanliness of the brushing operation and the orderly heat dissipation.
