Description

Technical Field

[0001] This utility model relates to the field of battery pack technology, and in particular to a plastic wiring compartment cover suitable for energy storage battery packs. Background Technology

[0002] With the popularization of renewable energy and the continuous development of the new energy storage industry, battery packs are gradually being used in homes. However, this also brings potential dangers, necessitating continuous improvements in product safety. Currently, most battery packs have the positive and negative output terminals directly exposed. Improper operation (such as accidental contact by children) could lead to short circuits due to conductive foreign objects directly contacting the terminals, endangering personal safety. Some countries have even established safety regulations requiring that the positive and negative output terminals not be directly exposed. Therefore, these battery packs pose a safety hazard. Furthermore, harsh environments (such as direct sunlight) accelerate terminal aging, reduce current carrying capacity, and affect overall product performance. To address this, a wiring compartment solution has been designed on the market. The principle is to use a sheet metal wiring compartment cover to isolate the output positive and negative terminals, communication terminals, DIP switches, etc., into a separate space. This design increases manufacturing costs, occupies internal space, increases overall size, and affects the product's appearance. Utility Model Content

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings of the embodiments. This utility model is not limited to the following specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0024] like Figures 1 to 6 As shown, a plastic wiring compartment 500 cover plate 200 suitable for energy storage battery packs includes: a battery pack body 100, a cover plate 200, fixing screws 300, and three limiting screws 400; the wiring compartment 500 is provided at the upper right corner of the battery pack body 100, and the three limiting screws 400 are all provided on one side of the wiring compartment 500; the cover plate 200 is provided with three connection points 600, and each limiting screw 400 is movably located within one of the connection points 600; the wiring compartment 500 has a first screw hole 510, the cover plate 200 has a second screw hole 210, and the fixing screw 300 partially passes through the second screw hole 210 and is threadedly connected to the first screw hole 510.

[0025] Specifically, the cover plate 200 is made of ABS+PC, and its heat distortion temperature can reach 80℃. The inner side of the cover plate 200 is provided with crisscrossing reinforcing ribs 220, which are used to improve the strength of the cover plate 200. Each connection 600 has a latching groove 610, and each latching groove 610 has chamfers 620 on both outer sides, with the two chamfers 620 corresponding to each other. Each latching groove 610 has two protrusions 630 on its side, with the two protrusions 630 corresponding to each other. One side of the wiring compartment 500 has several terminals 520, and the battery pack body 100 is electrically connected to the outside through these terminals 520. The wiring compartment 500 is inclined on the battery pack body 100. A wiring port 230 is provided on one side of the cover plate 200, through which external wires are connected to any of the terminals 520 on the wiring compartment 500. It is worth mentioning that the cross-sectional shape of the wiring port 230 is trapezoidal.

[0026] In the above embodiments, the top of each limiting screw 400 is an internal hexagonal groove, and the upper diameter of the internal hexagonal groove is 6mm and the middle diameter is 4mm. The lower part of the limiting screw 400 is an M4 external thread, and each limiting screw 400 is detachably mounted on one side of the wiring compartment 500 by means of thread engagement.

[0027] In other words, by placing the wiring compartment 500 in the upper right corner of the battery pack body 100, the internal space of the product is made reasonable, without increasing the overall space of the battery pack body 100. This also minimizes the wiring distance between the various terminals 520 on the battery pack body 100 and the external wiring, reducing the cost of power cables. Furthermore, the cover plate 200 is made of ABS+PC, with a material ratio of 70% ABS and 30% PC. Since its heat distortion temperature can reach 80℃, it meets the toughness requirements for use in the battery pack body 100.

[0028] During installation, the operator first connects the external wiring to the terminal 520 on the battery pack body 100 to establish conductivity. This means that both the power and communication lines of the battery pack body 100 are connected to the external circuitry via terminal 520. After connection, the operator closes the cover plate 200, aligning the three locking slots 610 with the three limiting screws 400. Then, the operator pushes the cover plate 200, causing each limiting screw 400 to enter the locking slot 610. Since each locking slot 610 has two protrusions 630 on its inner surface, these protrusions effectively restrain the limiting screws 400. Furthermore, under the action of external force, the limiting screw 400 can be forced to pass through the middle of the two protrusions 630. That is, by pushing the cover plate 200, the limiting screw 400 can pass through the middle of the two protrusions 630 and be engaged in the locking groove 610, or by pulling the cover plate 200, the limiting screw 400 can pass through the middle of the two protrusions 630 and come out of the locking groove 610. In other words, the operator can directly align the screws by pushing the cover plate 200 to simultaneously push all three limiting screws 400 into the locking groove 610 to restrict their position. At this time, the first screw hole 510 and the second screw hole 210 will be aligned. Then, by screwing in the fixing screw 300, the fixing screw 300 passes through the second screw hole 210 and is threadedly connected to the first screw hole 510, thereby fixing the entire cover plate 200 to the wiring compartment 500.

[0029] It is worth mentioning that, because of the wiring port 230, the entire process of fixing the cover plate 200 will not affect the wiring, which can ensure that the wiring can be smoothly sent out.

[0030] In summary, the above embodiments are not limiting embodiments of this utility model. Any modifications or equivalent variations made by those skilled in the art based on the substantive content of this utility model are within the technical scope of this utility model.
