Abstract
Description
Technical Field
[0001] This utility model relates to the field of backup power supplies for mining, and in particular to a housing structure for a backup power supply for mining. Background Technology
[0002] Early small-scale mining backup power supply enclosures primarily focused on basic protection of the internal power components. Their structures were relatively simple, often using a single material and simple shapes, such as the common rectangular enclosure. They only provided basic dust and water protection, and their ease of installation and adaptability were poor. With the development of mining technology and the increasing demands for power stability and safety, enclosure structures have begun to diversify and become more complex.
[0003] Currently, the common technologies for the design of small mining backup power supply housings include integrated injection-molded housings and assembled structures.
[0004] Integrated injection-molded housings offer advantages such as good integrity and strong sealing, effectively resisting harsh environments like moisture and dust in mines. However, while integrated injection-molded housings provide excellent sealing, internal malfunctions can lead to significant repair difficulties, as disassembly may damage the housing, increasing repair costs and time.
[0005] Prefabricated structures are assembled from multiple components, facilitating production and maintenance. Regarding installation methods, some prefabricated structures are wall-mounted, secured to the mine wall with bolts via mounting holes on the back of the casing; others are floor-mounted, placed on the ground using support feet. While prefabricated structures facilitate maintenance, gaps between components during assembly may affect the overall sealing and protective performance. Furthermore, wall-mounted installations may be unstable due to unevenness in the mine wall surface, even at different locations.
[0006] Therefore, how to improve the sealing and protective performance of the casing while ensuring ease of maintenance is a problem that needs to be solved. Summary of the Invention
[0007] The technical problem to be solved by this utility model is how to improve the sealing and protection performance of the housing while making it easy to maintain, and to provide a mining backup power supply housing structure.
[0008] To address the aforementioned problems, this utility model provides a mining backup power supply housing structure, comprising: a housing having an opening; a battery module mounting bracket fixed within the housing, the battery module mounting bracket being used to fix a battery module, the battery module mounting bracket including a first end plate and a second end plate disposed opposite to each other, the first end plate being disposed on the side near the opening of the housing for assembling a power circuit board; a cover plate disposed at the opening of the housing; and potting compound further disposed within the housing to encapsulate the battery module mounting bracket and the battery module.
[0009] The aforementioned technical solution adopts a modular design, combining an assembled structure with a potting process. This enhances the sealing performance of the battery cell while solving the problems of difficult or costly repairs associated with traditional integrated potting processes. The assembled structure allows for convenient and precise assembly of each module. After assembly, the gaps and critical areas are sealed using a potting process. Compared to traditional integrated potting processes, this not only effectively enhances the sealing performance of the battery cell but also cleverly solves the thorny problems faced by traditional processes. In traditional integrated potting processes, once a fault occurs, repairs are extremely difficult due to the solidified nature of the entire assembly, often requiring significant manpower, resources, and time for disassembly and repotting. However, the modular and assembled approach of this design allows for individual disassembly and repair of the power circuit board by simply removing the cover plate when a fault occurs, greatly reducing repair costs and improving the maintainability and lifespan of the equipment.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Please see Figures 1 to 8 ,in, Figure 1 This is a three-dimensional structural diagram of an embodiment of the mine backup power supply housing structure described in this utility model; Figure 2 This is a three-dimensional structural diagram of the housing of one embodiment of the mining backup power supply housing structure of this utility model; Figure 3 This is a front view of the housing of one embodiment of the mine backup power supply housing structure described in this utility model; Figure 4 This is a three-dimensional structural diagram of the cover plate of one embodiment of the mine backup power supply housing structure of the present utility model.

Figure 8 This is a three-dimensional structural diagram of an embodiment of the mining backup power supply housing structure of this utility model after the cover plate has been removed.
[0022] like Figures 1 to 8 As shown, the mining backup power supply housing structure of this utility model includes: a housing 11, a cell module fixing frame 12, and a cover plate 13. The housing 11 has an opening 110. The cell module fixing frame 12 is fixed inside the housing 11 and is used to fix the cell module 14. The cell module fixing frame 12 includes a first end plate 121 and a second end plate 122 disposed opposite to each other. The first end plate 121 is disposed on the side near the opening 110 of the housing 11 and is used to assemble the power circuit board 15. The cover plate 13 is disposed at the opening 110 of the housing 11. The housing 11 is further provided with potting compound (not shown) to wrap the cell module fixing frame 12 and the cell module 14.
[0023] The above technical solution adopts a modular design, combining an assembled structure with a potting process. The battery cell module is secured by the compression force of the first and second end plates of the cell module mounting bracket, which is then assembled and fixed within the housing. Further potting adhesive is used to assist in securing the battery cell module. This enhances the sealing performance of the battery cell while solving the problems of difficult or costly repairs associated with traditional integrated potting processes. The assembled structure allows for convenient and precise assembly of each module. After assembly, the potting process seals any gaps and critical areas.
[0024] Meanwhile, encapsulating the battery cell module with potting compound also provides heat dissipation, insulation, and vibration resistance, further protecting the module. The potting process offers advantages such as good integrity and strong sealing, effectively resisting the harsh environments of mines, including humidity and dust. Compared to traditional integrated potting processes, this not only effectively enhances the sealing performance of the battery cell but also cleverly solves the challenging problems faced by traditional methods.
[0025] In traditional integrated encapsulation processes, once a fault occurs, the overall curing characteristics make repairs extremely difficult, often requiring significant manpower, material resources, and time to disassemble and re-encapsulate. However, the modular and assembly-based approach of this design allows for the individual disassembly and repair of the power circuit board by simply removing the cover plate when a fault occurs, greatly reducing repair costs and improving the maintainability and lifespan of the equipment.
[0026] like Figures 2-3As shown, in some embodiments, each surface of the housing 11 has a plurality of first mounting holes 111, and a plurality of first rivet nuts 161 are provided on each surface corresponding to the first mounting holes 111, for fixing the housing 11 to the external environment. Specifically, the housing 11 is fixed to the external environment by screwing a first screw (not shown) into the first mounting hole 111 from the outside of the housing 11, and then tightening it with the first rivet nut 161. In this embodiment, the first rivet nut 161 is an M8 rivet nut.
[0027] In this embodiment, the housing 11 is a rectangular structure with a length, width and height of 130.5mm*74.5mm*159mm, and is equipped with five mounting surfaces in addition to the cover plate 13, which can meet the assembly requirements of multiple angles under multiple working conditions.
[0028] like Figure 2 and Figure 4 As shown, in some embodiments, each surface of the housing 11 has a plurality of second mounting holes 112 near the opening 110; the edge of the cover plate 13 has an inwardly turned surface 130, each inwardly turned surface 130 having a plurality of cover plate mounting holes 131, and a plurality of second rivet nuts 162 corresponding to the cover plate mounting holes 131 are provided in the inwardly turned surface 130 for fixing to the housing 11 through the second mounting holes 112. Specifically, the cover plate 13 is fixed to the housing 11 by screwing a second screw from the outside of the housing 11 into the second mounting hole 112, and then tightening it with the second rivet nut 162. In this embodiment, the second rivet nut 162 is an M3 rivet nut.
[0029] like Figure 1 and Figure 4 As shown, in some embodiments, the surface of the cover plate 13 is provided with a power display hole 132 and an external information interaction plug-in opening 133.
[0030] like Figure 2 and Figure 5 As shown, in some embodiments, each surface of the housing 11 is provided with a plurality of third mounting holes 113; the battery module mounting bracket 12 further includes two opposing side plates 123, each side plate 123 having a plurality of mounting holes 1231, and a plurality of second rivet nuts 162 provided on the surface of the side plate 123 corresponding to the mounting holes 1231, for fixing to the housing 11 through the third mounting holes 113. Specifically, by screwing a second screw from the outside of the housing 11 into the third mounting hole 113, and then tightening it with the second rivet nuts 162, the battery module mounting bracket 12 is fixed to the housing 11.
[0031] like Figure 5 and Figure 6 As shown, in some embodiments, the side plate 123 is further provided with a transversely adjustable slot 1232, the transversely adjustable slot 1232 having a length along the line connecting the first end plate 121 and the second end plate 122; the first end plate 121 and the second end plate 122 can move along the transversely adjustable slot 1232 to adjust the distance between the first end plate 121 and the second end plate 122.
[0032] By finely adjusting the spacing between the first end plate 121 and the second end plate 122, the cell module fixing bracket 12 has an adjustable fastening force function, which can reduce the precision requirements for the length consistency of the cell module 14 and simplify the assembly process. The cell module fixing bracket 12 can adaptively adjust the clamping force on the cell module 14, which greatly improves the tolerance of the assembly process to length deviations.
[0033] In some embodiments, the first end plate 121 and the second end plate 122 are provided with bent portions 1210 on both sides. The bent portions 1210 have end plate mounting holes (not shown). The inner surface of the bent portions 1210 is provided with a second rivet nut 162 corresponding to the end plate mounting hole, for fixing to the side plate 123 through the lateral adjustable slot 1232. Specifically, the side plate 123 is fixed to the bent portion 1210 by screwing a second screw from the outside of the side plate 123 into the lateral adjustable slot 1232 and then tightening it with the second rivet nut 162. The relative position of the end plate mounting hole and the lateral adjustable slot 1232 is adjusted by moving the second screw within the lateral adjustable slot 1232, thereby adjusting the distance between the first end plate 121 and the second end plate 122, so that the battery cell module fixing bracket 12 has an adjustable fastening force function, which can reduce the precision requirements for the consistency of the length of the battery cell module 14 and simplify the assembly process.
[0034] In some embodiments, the cell module mounting bracket 12 can mount three of the cell modules 14. In other embodiments, the cell module mounting bracket 12 can also be configured to mount two, four, or five of the cell modules 14.
[0035] like Figure 5 and Figure 7 As shown, in some embodiments, the surface of the first end plate 121 is provided with welding studs 1211, and the power circuit board 15 is fixed to the surface of the first end plate 121 by the welding studs 1211. After the battery cell module 14 and the power circuit board 15 are installed, electrical wiring is performed between the battery cell module 14 and the power circuit board 15.
[0036] In some embodiments, the potting compound encapsulates the cell module mounting bracket 12 and the cell module 14, exposing the power circuit board 15 at the first end plate 121. In this embodiment, after the cell module mounting bracket 12 completes the electrical wiring and is pushed into the housing 11, it is encapsulated with black silicone thermally conductive and flame-retardant potting compound, which not only provides auxiliary fixation but also enhances the heat dissipation of the cell module and the reliability of the wiring.
[0037] The potting compound firmly fixes the battery module mounting bracket 12 and the battery module 14, effectively preventing the internal structure of the battery module 14 from loosening due to external forces such as vibration and displacement. This ensures that the battery module 14 maintains a stable working state under complex operating conditions, greatly improving the structural stability and reliability of the battery module 14. At the same time, the potting compound has good thermal conductivity, and its internal microstructure can build an efficient thermal conduction channel.
[0038] Furthermore, the potting compound intentionally exposes the power circuit board 15 at the first end plate 121, a design that greatly facilitates the daily maintenance, testing, and functional expansion of the power circuit board 15. For example... Figure 8 As shown, when the power circuit board 15 malfunctions, maintenance personnel can easily operate the power circuit board 15 by simply removing the cover plate 13. This eliminates the need for complex disassembly procedures, allowing for tasks such as component replacement and software upgrades, significantly improving equipment maintainability and reducing maintenance costs throughout the equipment's lifecycle. This design, combining potting and exposure, ensures the stability of critical internal components without affecting the normal operation of the power circuit board 15, contributing to improved overall equipment performance and operating efficiency, and laying a solid foundation for long-term stable use.
[0039] In other embodiments, the battery cell module mounting bracket 12 or the battery cell module 14 can also be removed from the potting compound for maintenance. The mining backup power supply housing structure of this invention combines a prefabricated structure with a potting process, enhancing the sealing performance of the battery cells while solving the problems of difficult or costly maintenance associated with traditional integrated potting processes.
