Description

Technical Field

[0001] This invention relates to the field of battery technology, and in particular to an explosion-proof integrated battery and lighting device. Background Technology

[0002] Batteries are a core component of lighting equipment such as lamps, and their performance directly determines the equipment's battery life, lighting brightness, and overall safety level. Therefore, battery capacity and safety are primary considerations when selecting a model. To extend battery life and meet high power consumption requirements, lighting equipment generally uses large-capacity batteries; at the same time, to ensure safety, the equipment is usually equipped with explosion-proof structures to effectively suppress electric arcs, sparks, or high temperatures, preventing the ignition of flammable gases or explosive mixtures such as dust in the surrounding environment.

[0003] In existing technologies, increasing battery capacity is generally achieved by integrating multiple battery cells. However, this design significantly increases battery size, limiting its application in portable lighting devices. Regarding explosion-proof structures for lighting devices, existing solutions mainly include placing the explosion-proof structure outside the battery and integrating it inside the battery. However, in the first solution, the battery itself does not have explosion-proof capabilities, still posing a safety hazard. In the second solution, the explosion-proof structure encroaches on the space of the battery cells, leading to a decrease in battery capacity and failing to meet the long-lasting battery life requirements of lighting devices.

[0004] Therefore, there is an urgent need for an explosion-proof integrated battery and lighting device to solve the above problems. Summary of the Invention

This not only increases the number of battery cells that can be installed between the first and second supports, allowing the explosion-proof integrated battery to have a larger capacity to meet the requirements of long battery life and high power consumption of the lighting device, but also helps to reduce the space occupied by the explosion-proof integrated battery, meeting the application requirements of the explosion-proof integrated battery in portable lighting devices. On the other hand, the heat dissipation gap also allows the heat generated by the battery cells during use to be quickly dissipated to the outside, effectively reducing the internal temperature of the explosion-proof integrated battery, delaying the process of thermal runaway, achieving the purpose of explosion protection, and improving the safety of the explosion-proof integrated battery. In addition, the explosion-proof filler in the first and second filling slots can effectively seal the gaps and holes at both ends of the battery cell, forming a protective barrier for the explosion-proof integrated battery. This effectively prevents the gas generated inside the explosion-proof integrated battery from leaking into the external environment. Not only does the explosion-proof integrated battery itself achieve effective explosion protection, but it also does not encroach on the space of the battery cell. While improving the explosion-proof effect of the explosion-proof integrated battery, it also ensures the capacity of the explosion-proof integrated battery. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0023] Example 1 like Figures 1 to 9 As shown, this embodiment provides an explosion-proof integrated battery with a large capacity, a small footprint, and explosion-proof functionality.

[0024] See Figure 1 , Figure 2 and Figure 3 The explosion-proof integrated battery includes a first bracket 100, a second bracket 200, multiple battery cells 310, and explosion-proof filler 400. The first bracket 100 and the second bracket 200 are arranged at intervals along the power supply direction. A first filling groove 111 is provided on the side of the first bracket 100 away from the second bracket 200, and a second filling groove 211 is provided on the side of the second bracket 200 away from the first bracket 100. Multiple battery cells 310 are disposed between the first bracket 100 and the second bracket 200, and a heat dissipation gap 320 is formed between any two adjacent battery cells 310. The first filling groove 111 and the second filling groove 211 are both filled with explosion-proof filler 400.

[0025] The explosion-proof integrated battery provided in this embodiment has a heat dissipation gap 320 formed between two adjacent cells 310. On the one hand, because the heat dissipation gap 320 is small, the distance between two adjacent cells 310 can be reduced, which not only increases the number of cells 310 that can be installed between the first bracket 100 and the second bracket 200, but also allows the explosion-proof integrated battery to have a larger capacity to meet the requirements of long battery life and high power consumption of lighting equipment. It also helps to reduce the space occupied by the explosion-proof integrated battery, which meets the application requirements of the explosion-proof integrated battery in portable lighting equipment. On the other hand, the setting of the heat dissipation gap 320 also allows the heat generated by the cells 310 during use to be quickly dissipated to the outside, effectively reducing the internal temperature of the explosion-proof integrated battery, delaying the process of thermal runaway, achieving the purpose of explosion protection, and improving the safety of the explosion-proof integrated battery. Furthermore, the explosion-proof filler 400 in the first filling groove 111 and the second filling groove 211 can effectively seal the gaps and holes at both ends of the cell 310, forming a protective barrier for the explosion-proof integrated battery. This effectively prevents the gas generated inside the explosion-proof integrated battery from leaking into the external environment. Not only does the explosion-proof integrated battery itself achieve effective explosion protection, but it also does not encroach on the space of the cell 310. While improving the explosion-proof effect of the explosion-proof integrated battery, it also ensures the capacity of the explosion-proof integrated battery.

[0026] The power supply direction is the extension direction of the battery cell 310 between the first bracket 100 and the second bracket 200.

[0027] In this embodiment, the explosion-proof filler 400 is a potting compound. Before curing, the potting compound is fluid. After curing, the potting compound becomes a high-performance thermosetting polymer insulating material, which can play a role in waterproofing, moisture-proofing, dustproofing, insulation, thermal conductivity, confidentiality, corrosion resistance, temperature resistance, and shock absorption.

[0028] Specifically, some potting compounds (especially silicone potting compounds) possess excellent flame-retardant properties. When thermal runaway occurs in the explosion-proof integrated battery, they can absorb heat through their own chemical reactions or form a non-combustible char layer covering the surface of the battery, isolating oxygen and thus inhibiting further combustion. Furthermore, some high-performance potting compounds (such as thermally conductive potting compounds) have good thermal conductivity, which can more effectively conduct the heat generated inside the explosion-proof integrated battery to the outside, thereby rapidly reducing the local temperature inside the battery and delaying the process of thermal runaway.

[0029] Optionally, see Figure 4 and Figure 5The first bracket 100 includes a first support 110 and a plurality of first limiting posts 120 disposed on the first support 110. A first filling groove 111 is disposed on the first support 110. The plurality of first limiting posts 120 are arranged at intervals along the circumference of the first support 110. The second bracket 200 includes a second support 210 and a plurality of second limiting posts 220 disposed on the second support 210. A second filling groove 211 is disposed on the second support 210. The plurality of second limiting posts 220 are connected one-to-one with the plurality of first limiting posts 120. The plurality of first limiting posts 120 and the plurality of second limiting posts 220 surround and form an installation space. The plurality of battery cells 310 are all located within the installation space. Multiple first limiting posts 120 and multiple second limiting posts 220 can effectively constrain the movement of the battery cell 310 between the first support 110 and the second support 210, improving the reliability of the battery cell 310 installation between the first bracket 100 and the second bracket 200. Moreover, the multiple first limiting posts 120 and multiple second limiting posts 220 are spaced apart, so that multiple gaps can be formed in the circumferential direction of the installation space, which is conducive to the further outward dissipation of heat from the battery cell 310, effectively reducing the internal temperature of the explosion-proof integrated battery and improving the safety of the explosion-proof integrated battery.

[0030] In this embodiment, the explosion-proof integrated battery further includes a plurality of first fasteners, which are arranged at circumferential intervals along the first support 110. The first fasteners pass through the first support 110 and the mounting space and are fastened to the second support 210, or the first fasteners pass through the second support 210 and the mounting space and are fastened to the first support 110, thereby firmly connecting the first bracket 100 and the second bracket 200. At this time, the plurality of first limiting posts 120 and the plurality of second limiting posts 220 are aligned one-to-one.

[0031] Specifically, see Figure 6 and Figure 7 Each of the first support 110 and the second support 210 has a connecting post 130 on one side facing each other, which corresponds to a plurality of first fasteners. One of the connecting posts 130 of the first support 110 and the second support 210 has a threaded hole 131, and the other of the connecting posts 130 of the first support 110 and the second support 210 has a first mounting hole 231. The first fastener passes through the corresponding first mounting hole 231 and is threadedly connected to the wall of the corresponding threaded hole 131.

[0032] For example, the first fastener is a bolt or screw.

[0033] In this embodiment, see Figure 3 , Figure 6 and Figure 7The first support 110 is provided with a first mounting slot 112 corresponding to each of the multiple battery cells 310, and the second support 210 is provided with a second mounting slot 212 corresponding to each of the multiple battery cells 310. One end of the battery cell 310 is engaged in the corresponding first mounting slot 112, and the other end of the battery cell 310 is engaged in the corresponding second mounting slot 212. The first mounting slot 112 and the second mounting slot 212 not only further constrain the movement of the battery cell 310 in the installation space, improving the reliability of the battery cell 310 installed between the first support 100 and the second support 200, but also ensure that a heat dissipation gap 320 can be formed between two adjacent battery cells 310, improving the safety of the explosion-proof integrated battery. In addition, when the battery cell 310 is installed between the first support 100 and the second support 200, the first mounting slot 112 and the second mounting slot 212 enable the battery cell 310 to be quickly positioned and installed, improving the efficiency of the explosion-proof integrated battery assembly.

[0034] Optionally, see Figure 3 The explosion-proof integrated battery includes multiple sets of cell groups 300 connected in sequence. A heat dissipation gap 320 is formed between any two connected sets of cell groups 300. Each set of cell groups 300 includes multiple cells 310. Connection points are provided on the cell groups 300. The multiple cells 310 of each set of cell groups 300 are radially distributed with the connection points as the center, and the connection points of the multiple sets of cell groups 300 are common. This arrangement allows the multiple sets of cell groups 300 to approximately form a circle with the connection points as the center, and the multiple cells 310 to approximately form multiple concentric circles with the connection points as the centers. This not only ensures that a heat dissipation gap 320 is formed between any two adjacent cells 310, ensuring the explosion-proof effect of the explosion-proof integrated battery, but also helps to reduce the space occupied by the multiple cells 310 as a whole, meeting the application requirements of the explosion-proof integrated battery in portable lighting equipment.

[0035] Specifically, see Figure 3 The cross-sectional shape of the first support 110 and the cross-sectional shape of the second support 210 are both circular, and the center of the first support 110 and the center of the second support 210 are coaxial with the connection point. The radius of the first support 110 and the radius of the second support 210 are the same as the radius of the battery cell assembly 300.

[0036] In this embodiment, the cross-sectional shape of the battery cell assembly 300 is triangular; in other embodiments, the cross-sectional shape of the battery cell assembly 300 is fan-shaped, as long as the cross-sectional shape of the battery cell assembly 300 is a pattern radiating outward from the connection point.

[0037] For example, the battery cell group 300 is provided in five groups, and each battery cell group 300 includes six battery cells 310. The six battery cells 310 are formed in three layers. The layer closest to the connection point has one battery cell 310, the layer next closest to the connection point has two battery cells 310, and the layer farthest from the connection point has three battery cells 310.

[0038] Optionally, see Figure 1 , Figure 2 and Figure 3 The explosion-proof integrated battery includes multiple cell groups 300, each cell group 300 comprising multiple cells 310. The battery also includes a main board 510, a protection board 520, and a circuit board 530. The main board 510 is connected to a first bracket 100. Both the main board 510 and the protection board 520 are located within a first filling groove 111, with the protection board 520 positioned on the side of the main board 510 facing the cells 310. Explosion-proof filler 400 within the first filling groove 111 encloses the main board 510 and the protection board 520. One end of each cell group 300 is electrically connected to the protection board 520. The circuit board 530 is located within a second filling groove 211, with the explosion-proof filler 400 within the second filling groove 211 enclosing the circuit board 530. The other end of each cell group 300 is electrically connected to the circuit board 530. This configuration ensures the explosion-proof effect of the integrated battery and improves its safety during use.

[0039] The circuit board 530 provides robust support and precise electrical connections, ensuring stable signal and power transmission between the explosion-proof integrated battery and other electronic components. The protection board 520 provides hardware-level protection against abnormal states during the charging and discharging process of the explosion-proof integrated battery (such as overcharge, over-discharge, overcurrent, short circuit, and high temperature), preventing damage or safety accidents. The main board 510 is responsible for data acquisition, status assessment, control decisions, and communication interaction to achieve intelligent management of the explosion-proof integrated battery. The circuit board 530, protection board 520, and main board 510 are all existing technologies in the field and will not be described in detail here.

[0040] For example, the motherboard 510 is fastened to the first bracket 100 by bolts or screws.

[0041] For example, the protection board 520 is electrically connected to the main board 510 via terminals, wires, and other components. Terminals and wires are existing technology in the field and will not be described in detail here.

[0042] For example, circuit board 530 is a PCB (Printed Circuit Board).

[0043] In this embodiment, see Figure 3The explosion-proof integrated battery also includes a first connecting strip group corresponding to each of the multiple cell groups 300. The first connecting strip group includes multiple first connecting strips 610, one end of which is connected to a cell 310 in the corresponding cell group 300, and the other end of which is connected to a protection board 520. This arrangement allows some cells 310 to be connected to the protection board 520 via the first connecting strips 610, ensuring effective current transmission between the cells 310 and the protection board 520.

[0044] For example, the battery cell group 300 is provided in five groups, each battery cell group 300 includes six battery cells 310, and the first connecting strip group is also provided in five groups, each first connecting strip group includes two first connecting strips 610, and the two first connecting strips 610 can be connected one-to-one with the two battery cells 310 in the corresponding battery cell group 300.

[0045] For example, the first connecting strip 610 is made of nickel strip. The nickel strip mainly undertakes core functions such as cell 310 connection and current transmission. Its high conductivity, corrosion resistance, weld strength and mechanical properties are key to ensuring the performance and safety of the explosion-proof integrated battery.

[0046] Specifically, see Figure 3 and Figure 8 The first bracket 100 is provided with a first connecting hole 113 corresponding to a plurality of first connecting strips 610. The first connecting hole 113 is coaxial with a battery cell 310. One end of the first connecting strip 610 is embedded in the first connecting hole 113 so that the first connecting strip 610 can be connected to a battery cell 310 in the corresponding battery cell group 300.

[0047] See Figure 8 The first connecting hole 113 is provided on the first support 110.

[0048] For example, see Figure 3 and Figure 8 The shape of the battery cell 310 is cylindrical, that is, the cross-sectional shape of the battery cell 310 is circular, the cross-sectional shape of the first connecting hole 113 is also circular, and the center of the battery cell 310 and the center of the first connecting hole 113 are coaxial.

[0049] Specifically, see Figure 3One end of the first connecting strip 610 is provided with a first connecting portion 611, and the other end of the first connecting strip 610 is provided with a first limiting plate 612. The protective plate 520 is provided with first through holes 5211 corresponding to the plurality of first connecting strips 610. The plurality of first through holes 5211 are arranged at intervals along the edge of the protective plate 520. The first connecting portion 611 is connected to a battery cell 310. The other end of the first connecting strip 610 passes through the corresponding first through hole 5211. The first limiting plate 612 is attached to the protective plate 520. The first limiting plate 612 can be attached to the protective plate 520, which not only increases the connection area between the first limiting plate 612 and the protective plate 520 and ensures the effective transmission of current to the protective plate 520, but also helps to reduce the space occupied by the first connecting strip 610 along the power supply direction, thereby reducing the volume of the explosion-proof integrated battery and meeting the application requirements of the explosion-proof integrated battery in portable lighting equipment. In addition, the first perforation 5211 is located at the edge of the protective plate 520, and the first connecting strip 610 passing through the first perforation 5211 can constrain the displacement of the protective plate 520 in the first filling groove 111, ensuring the reliability of the installation of the protective plate 520 in the first filling groove 111.

[0050] See Figure 3 and Figure 8 The first bracket 100 is provided with first connecting holes 113 corresponding to a plurality of first connecting strips 610. The first connecting part 611 is embedded in the corresponding first connecting hole 113 and welded to the corresponding battery cell 310. The first limiting plate 612 is electrically welded to the protection plate 520.

[0051] For example, see Figure 3 and Figure 8 The cross-sectional shape of the first connecting strip 610 is U-shaped, and the cross-sectional shape of the first connecting part 611 is the same as that of the first connecting hole 113.

[0052] For example, see Figure 3 and Figure 8 The battery cell group 300 is provided in five groups, and each group of battery cell group 300 includes six battery cells 310, which are formed in three layers. The first connecting strip group is provided in five groups, and each first connecting strip group includes two first connecting strips 610. There are two first connecting holes 113 and two first through holes 5211. The two first connecting holes 113 correspond one-to-one with two of the three battery cells 310 in the layer furthest from the connection point.

[0053] In this embodiment, see Figure 3The explosion-proof integrated battery also includes a second connecting strip group corresponding to each of the multiple cell groups 300. The second connecting strip group includes multiple second connecting strips 620. One end of each second connecting strip 620 is connected to multiple cells 310 in the corresponding cell group 300, and the cells 310 connected to the first connecting strip 610 and the cells 310 connected to the second connecting strip 620 are adjacent to each other. The other end of each second connecting strip 620 is connected to a protection plate 520. This arrangement allows some cells 310 to be connected to the protection plate 520 via only one second connecting strip 620, which not only helps reduce the number of second connecting strips 620 and lowers the manufacturing cost of the explosion-proof integrated battery, but also helps reduce the space occupied by the second connecting strip group, reducing the size of the explosion-proof integrated battery and meeting the application requirements of the explosion-proof integrated battery in portable lighting equipment.

[0054] For example, the battery cell group 300 is provided in five groups, each group of battery cell group 300 includes six battery cells 310, and the second connecting strip group is also provided in five groups, each group of second connecting strips includes two second connecting strips 620, and each second connecting strip 620 can be connected to two battery cells 310 in the corresponding battery cell group 300.

[0055] For example, the second connecting strip 620 is made of nickel strip.

[0056] Specifically, see Figure 3 and Figure 8 The first bracket 100 is provided with second connecting holes 114 corresponding to a plurality of second connecting strips 620. One end of the second connecting strip 620 is embedded in the corresponding second connecting hole 114. The second connecting hole 114 includes a first hole segment 1141 and a second hole segment 1142 that are connected. The first hole segment 1141 is coaxial with one of the plurality of battery cells 310, and the second hole segment 1142 is coaxial with another of the plurality of battery cells 310. The battery cell 310 coaxial with the first hole segment 1141 and the battery cell 310 coaxial with the second hole segment 1142 are arranged adjacent to each other. This arrangement allows the second connecting strip 620 to connect to two battery cells 310 in the corresponding battery cell group 300 at the same time.

[0057] See Figure 8 The second connecting hole 114 is provided on the first support 110.

[0058] For example, see Figure 3 and Figure 8The battery cell 310 is cylindrical in shape, meaning its cross-sectional shape is circular. The first hole segment 1141 and the second hole segment 1142 also have circular cross-sectional shapes, and the centers of both segments are coaxial with the center of the battery cell 310. The first connecting hole 113 also includes a third hole segment 1143, one end of which connects to the first hole segment 1141, and the other end connects to the second hole segment 1142. Therefore, the first connecting hole 113 has a dumbbell-shaped cross-section.

[0059] Specifically, see Figure 3 One end of the second connecting strip 620 is provided with a second connecting portion 621, and the other end of the second connecting strip 620 is provided with a second limiting plate 622. The protective plate 520 is provided with second through holes 5212 corresponding to the plurality of second connecting strips 620. The second connecting portion 621 is connected to a plurality of battery cells 310, and the other end of the second connecting strip 620 passes through the corresponding second through hole 5212. The second limiting plate 622 is attached to the protective plate 520. The second limiting plate 622 can be attached to the protective plate 520, which not only increases the connection area between the second limiting plate 622 and the protective plate 520 and ensures the effective transmission of current to the protective plate 520, but also helps to reduce the space occupied by the second connecting strip 620 along the power supply direction, thereby reducing the volume of the explosion-proof integrated battery and meeting the application requirements of the explosion-proof integrated battery in portable lighting equipment.

[0060] See Figure 3 and Figure 8 The first bracket 100 is provided with second connecting holes 114 corresponding to a plurality of second connecting strips 620. The second connecting part 621 is embedded in the corresponding second connecting hole 114 and welded to the corresponding battery cell 310. The second limiting plate 622 is electrically welded to the protection plate 520.

[0061] For example, see Figure 3 and Figure 8 The cross-sectional shape of the second connecting strip 620 is U-shaped, and the cross-sectional shape of the first connecting part 611 is the same as that of the first connecting hole 113.

[0062] For example, five sets of battery cell groups 300 are provided, each set of battery cell groups 300 includes six battery cells 310, and the six battery cells 310 are formed in three layers. Five sets of second connecting strip groups are provided, each set of second connecting strip groups includes two second connecting strips 620, and two second connecting holes 114 and two through holes 5212 are provided, each second connecting hole 114 corresponding to two battery cells 310 respectively.

[0063] In this embodiment, see Figure 3The explosion-proof integrated battery also includes third connecting strip groups corresponding to multiple cell groups 300. Each third connecting strip group includes multiple third connecting strips 630, which are connected to multiple cells 310 in their respective cell groups 300. The other end of each third connecting strip 630 is connected to a circuit board 530. This arrangement allows multiple cells 310 to be connected to the protection board 520 via only one third connecting strip 630. This not only helps reduce the number of third connecting strips 630 required, lowering the manufacturing cost of the explosion-proof integrated battery, but also reduces the space occupied by the third connecting strip groups, thus reducing the overall size of the explosion-proof integrated battery and meeting the application requirements of this explosion-proof integrated battery in portable lighting equipment.

[0064] For example, the battery cell group 300 is provided in five groups, each group of battery cell group 300 includes six battery cells 310, and the third connecting strip group is also provided in five groups, each group of third connecting strips includes three third connecting strips 630, and each third connecting strip 630 can be connected to two battery cells 310 in the corresponding battery cell group 300.

[0065] For example, the third connecting strip 630 is made of nickel strip.

[0066] Specifically, see Figure 3 and Figure 9 The second bracket 200 is provided with third connecting holes 213 corresponding to a plurality of third connecting strips 630. One end of the third connecting strip 630 is embedded in the corresponding third connecting hole 213. The third connecting hole 213 includes a fourth hole segment 2131 and a fifth hole segment 2132 connected in sequence. The fourth hole segment 2131 is coaxial with one of the plurality of battery cells 310, and the fifth hole segment 2132 is coaxial with another of the plurality of battery cells 310. The battery cell 310 coaxial with the fourth hole segment 2131 and the battery cell 310 coaxial with the fifth hole segment 2132 are arranged adjacent to each other. This arrangement allows the third connecting strip 630 to connect to two battery cells 310 in the corresponding battery cell group 300 at the same time.

[0067] See Figure 9 The third connecting hole 213 is provided on the second support 210.

[0068] For example, see Figure 3 and Figure 9 The battery cell 310 is cylindrical in shape, meaning its cross-sectional shape is circular. The fourth segment 2131 and the fifth segment 2132 also have circular cross-sectional shapes, and the centers of both segments are coaxial with the center of the battery cell 310. The third connecting hole 213 also includes a sixth segment 2133, one end of which connects to the fourth segment 2131, and the other end connects to the fifth segment 2132. Therefore, the cross-sectional shape of the third connecting hole 213 is dumbbell-shaped.

[0069] Specifically, see Figure 3 One end of the third connecting strip 630 is provided with a third connecting part 631, and the other end of the third connecting strip 630 is provided with a third limiting plate 632. The circuit board 530 is provided with third through holes 5311 corresponding to the multiple third connecting strips 630. The third connecting part 631 is connected to multiple battery cells 310, and the other end of the third connecting strip 630 passes through the corresponding third through hole 5311. The third limiting plate 632 is attached to the circuit board 530. The attachment of the third limiting plate 632 to the circuit board 530 not only increases the connection area between the third limiting plate 632 and the circuit board 530, ensuring effective current transmission to the circuit board 530, but also helps to reduce the space occupied by the third connecting strip 630 along the power supply direction, thereby reducing the volume of the explosion-proof integrated battery and meeting the application requirements of the explosion-proof integrated battery in portable lighting equipment.

[0070] See Figure 3 and Figure 9 The second bracket 200 is provided with third connection holes 213 corresponding to a plurality of third connection strips 630. The third connection part 631 is embedded in the corresponding third connection hole 213 and welded to the corresponding battery cell 310. The third limiting plate 632 is electrically welded to the circuit board 530.

[0071] For example, see Figure 3 and Figure 9 The cross-sectional shape of the third connecting strip 630 is U-shaped, and the cross-sectional shape of the third connecting part 631 is the same as that of the third connecting hole 213.

[0072] For example, the battery cell group 300 is provided in five groups, each group of battery cell group 300 includes six battery cells 310, and the six battery cells 310 are formed in three layers. The third connecting strip group is provided in five groups, each group of second connecting strip group includes three third connecting strips 630, and three third connecting holes 213 and three third through holes 5311 are provided, each third connecting hole 213 corresponding to two battery cells 310 respectively.

[0073] In this embodiment, see Figure 3The protection board 520 includes protection sub-boards 521 corresponding to each of the multiple cell groups 300. The other end of the second connecting strip group is connected to the corresponding protection sub-board 521. The circuit board 530 includes circuit sub-boards 531 corresponding to each of the multiple cell groups 300. The other end of the third connecting strip group is connected to the corresponding circuit sub-board 531. This arrangement allows each cell group 300 to independently supply power to its corresponding protection sub-board 521 and corresponding circuit sub-board 531. On the one hand, when a cell group 300 malfunctions, it will not affect the normal operation of other cell groups 300, other circuit sub-boards 531, and other circuit sub-boards 531. This not only achieves fault isolation and improves the safety of the explosion-proof integrated battery, but also enables precise fault location and improves maintenance convenience. On the other hand, it also helps to rationally distribute current within the explosion-proof integrated battery, improves the accuracy of current control, and enhances charging and discharging efficiency.

[0074] Specifically, see Figure 3 Each protection sub-board 521 is provided with a first through hole 5211 and a second through hole 5212, and the number of first through holes 5211 on each protection sub-board 521 is the same as the number of first connecting strips 610 in each group of first connecting strips, and the number of second through holes 5212 on each protection sub-board 521 is the same as the number of second connecting strips 620 in each group of second connecting strips; each circuit sub-board 531 is provided with a third through hole 5311, and the number of third through holes 5311 on each circuit sub-board 531 is the same as the number of third connecting strips 630 in each group of third connecting strips.

[0075] For example, see Figure 3 The battery cell assembly 300 is provided with five sets, and the protection sub-board 521 and the circuit sub-board 531 are each provided with five sets. The cross-sectional shape of the protection sub-board 521 and the circuit sub-board 531 is fan-shaped, and the cross-sectional shape of the protection board 520 and the circuit board 530 is circular.

[0076] In this embodiment, see Figure 3 The explosion-proof integrated battery also includes multiple fourth connecting straps 640, which are arranged circumferentially around the first bracket 100. One end of each fourth connecting strap 640 is connected to the edge of the protection plate 520, and the other end is connected to the edge of the circuit board 530. This arrangement not only achieves electrical connection between the circuit board 530 and the protection plate 520, but also effectively constrains the displacement of the protection plate 520 and the circuit board 530, ensuring the reliability of their installation.

[0077] For example, the fourth connecting strip 640 is made of nickel strip.

[0078] Specifically, see Figure 3Multiple fourth connecting strips 640 are disposed on the outer periphery of multiple battery cells 310 and are connected one-to-one with the outermost multiple battery cells 310.

[0079] For example, the battery cell group 300 is provided in five groups, and each battery cell group 300 includes six battery cells 310. The six battery cells 310 are formed in three layers. The layer closest to the connection point has one battery cell 310, the layer next closest to the connection point has two battery cells 310, and the layer farthest from the connection point has three battery cells 310. Therefore, there are a total of fifteen battery cells 310 on the outermost side, and the fourth connecting strip 640 is provided with fifteen of them.

[0080] Specifically, see Figure 3 and Figure 5 The protection board 520 includes a protection sub-board 521 corresponding to each of the multiple battery cell groups 300. The edge of the protection sub-board 521 is provided with multiple fourth through holes 5213. One end of the fourth connecting strip 640 is provided with a fourth limiting plate 641, which passes through the fourth through holes 5213 and is attached to the protection sub-board 521. The circuit board 530 includes a circuit sub-board 531 corresponding to each of the multiple battery cell groups 300. The second bracket 200 is provided with multiple fifth through holes 214. The other end of the fourth connecting strip 640 is provided with a fifth limiting plate 642, which passes through the fifth through holes 214 and is attached to the circuit sub-board 531.

[0081] For example, see Figure 3 The cross-sectional shape of the fourth connecting strip 640 is U-shaped.

[0082] Example 2 This embodiment provides a lighting device, including a light-emitting element and an explosion-proof integrated battery as described in Embodiment 1. The explosion-proof integrated battery is electrically connected to the light-emitting element and is configured to supply power to the light-emitting element.

[0083] Specifically, the light-emitting element is electrically connected to the circuit board 530 of the explosion-proof integrated battery.

[0084] In this embodiment, the lighting equipment includes fixed lighting equipment and portable lighting equipment. Fixed lighting equipment includes, but is not limited to, household lighting equipment (such as ceiling lights, chandeliers, and wall lights), commercial lighting equipment (such as spotlights, track lights, and panel lights), and industrial and public lighting (such as mining lamps, streetlights, and explosion-proof lights). Portable lighting equipment includes, but is not limited to, handheld lighting equipment (such as flashlights and headlamps), wearable lighting equipment (such as safety helmet lights), and mobile lighting equipment (such as emergency lights and work lights).

[0085] In this embodiment, the light-emitting element is a light bulb.

[0086] In this embodiment, see Figure 4The second support 210 is provided with a plurality of second mounting holes 215 arranged at intervals along its circumference. The explosion-proof integrated battery also includes a second fastener corresponding to each of the plurality of second mounting holes 215. The second fastener passes through the corresponding second mounting hole 215 and is fastened to the external structure to achieve a stable installation of the explosion-proof integrated battery on the lighting equipment.

[0087] Specifically, see Figure 4 The multiple second mounting holes 215 are divided into multiple groups, with each group including two second mounting holes 215. The distance between the two second mounting holes 215 in each group is less than the distance from the second mounting hole 215 in that group to the second mounting hole 215 in the adjacent group. This arrangement not only ensures a stable circumferential connection between the second support 210 and the external structure, but also increases the connection strength at each connection point, further improving the reliability of the explosion-proof integrated battery when installed on lighting equipment.

[0088] For example, the second fastener is a bolt or screw.
