[0023] Hereinafter, the technical aspects of the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and are not all embodiments. Based on the embodiments of the present invention, all other embodiments that can be obtained by those skilled in the art without creative labor fall within the protection scope of the present invention.

[0024] 1 to 17, the energy storage power supply includes an energy storage housing 1, a plurality of batteries 21, a first electrode sheet 3, and a second electrode sheet 4. The energy storage housing 1 is provided with a plurality of battery chambers (battery storage sections) 11. A first opening 111 is provided at one end of the battery chamber 11, and a second opening 112 is provided at the other end of the battery chamber 11. When a battery 21 is inserted into the battery chamber 11 through the first opening 111 or the second opening 112, the first electrode sheet 3 caps the first opening 111 and the second electrode sheet 4 caps the second opening 112, so that the first electrode sheet 3 is connected to the positive electrode of the battery 21 and the second electrode sheet 4 is connected to the negative electrode of the battery 21. With the above configuration, the energy storage power supply includes an energy storage housing, a plurality of batteries, a first electrode sheet, and a second electrode sheet, the energy storage housing is provided with a plurality of battery chambers, one end of the battery chamber is provided with a first opening, and the other end of the battery chamber is provided with a second opening, and when a battery is inserted into the battery chamber through the first opening or the second opening, the first electrode sheet caps the first opening and the second electrode sheet caps the second opening, whereby the first electrode sheet is connected to the positive electrode of the battery and the second electrode sheet is connected to the negative electrode of the battery, thereby producing an energy storage power supply. In this case, a plurality of batteries are directly inserted into the battery chamber, and the plurality of batteries are fixed in the battery chamber via the first electrode sheet and the second electrode sheet, and the plurality of batteries are connected in parallel or in series to form a large-capacity battery pack, which provides the energy storage power source with the functions of energy storage and power supply, is easy to assemble, and replaces the ordinary battery bags available on the market, by eliminating a series of processes such as binding, gluing, filling, blow molding, sealing and decorating the plurality of batteries, which is environmentally friendly and convenient for automated production, which reduces the defective rate of the energy storage power source, and improves the production efficiency and safety. In addition, compared with the battery bags available on the market, the battery chamber can be inserted and the plurality of batteries can be spaced apart from each other, and the heat released during the operation of the batteries is released to the outside through the energy storage housing, which greatly improves the heat dissipation and safety of the energy storage power source. In addition, the battery bags of the commercially available energy storage power sources are easily disassembled and scattered when the energy storage power source is hit or dropped.In this application, batteries are inserted into multiple battery compartments of an energy storage housing, and the multiple batteries are fixed in the battery compartments via first and second electrode sheets, and the multiple batteries are connected in parallel or in series, making the structure more robust. Even if the energy storage power source is hit or dropped, the batteries are firmly fixed in the battery compartments without scattering, so that the energy storage power source can stably store energy and supply power, greatly improving the drop resistance and safety of the energy storage power source.

[0025] Specifically, the batteries 21 constitute at least one battery pack 2. In the embodiment of the present application, four sets of battery packs 2 will be described as an example, and each battery pack 2 includes five batteries 21. Accordingly, the number of battery compartments 11 is four, each battery compartment 11 includes five battery mounting positions 117, and both ends of each battery mounting position 117 are first openings 111 and second openings 112, respectively. Five adjacent first openings 111 communicate with each other to form openings 11a, or five adjacent second openings 112 also communicate with each other to form openings 11a, forming a total of four sets of openings 11a, and the four sets of openings 11a are located on opposite sides of the energy storage housing 1, and the two sets of openings 11a on the same side are spaced apart. Since the opening 11a is large, when mounting the battery 21, the battery 21 can be easily inserted into the battery mounting position 117, and the battery pack 2 can easily slide into the battery pack 11 along the preset axial direction Z, further improving the assembly efficiency of the battery pack 2. The preset axial direction Z is the same as the axial direction of the battery mounting position 117. In this way, after mounting the battery pack 2 on one side, the first electrode sheet or the second electrode sheet on the corresponding side is mounted, and then the battery pack 2 on the other side is mounted, and the corresponding second electrode sheet or the first electrode sheet is mounted, thereby improving the assembly efficiency.

[0026] In order to ensure the independence, heat dissipation, and safety of each battery 21 after the batteries 21 are mounted in the battery mounting positions 117, a baffle plate 118 is provided between the battery mounting positions 117 in each battery chamber 11 to separate each of the two battery mounting positions 117 in each battery chamber 11. In order to ensure the mounting efficiency of the batteries 21, the length of the baffle plate 118 along the preset axial direction Z is smaller than the length of the side wall of the battery chamber 11 along the preset axial direction Z, that is, the extension distance of the baffle plate 118 along the preset axial direction Z at the battery mounting positions 117 is between the first opening 111 and the second opening 112, and the length is smaller than the distance between the first opening 111 and the second opening 112. Specifically, in this embodiment, the length of the baffle plate 118 is about half the depth of the battery mounting positions 117.

[0027] When the battery 21 is inserted into the battery compartment 11 through the first opening 111 or the second opening 112, the first electrode sheet 3 is connected to one side of the energy storage housing 1 and the second electrode sheet 4 is connected to the other side of the energy storage housing 1, such that the first electrode sheet 3 caps the first opening 111 and the second electrode sheet 4 caps the second opening 112, the first electrode sheet 3 is connected to the positive electrode of the battery 21, and the second electrode sheet 4 is connected to the negative electrode of the battery 21. Specifically, the first electrode sheet 3 is a first nickel strip, and the second electrode sheet 4 is a second nickel strip, and when the battery 21 is inserted into the battery chamber 11 through the first opening 111 or the second opening 112, the first nickel strip is welded to one side of the energy storage housing 1 and the second nickel strip is welded to the other side of the energy storage housing 1, so that the first nickel strip caps the first opening 111 and the second nickel strip caps the second opening 112, the first nickel strip is connected to the positive electrode of the battery 21, and the second nickel strip is connected to the negative electrode of the battery 21. Furthermore, the first nickel strip is welded to one side of the energy storage housing 1 by spot welding or laser welding, and the second nickel strip is welded to the other side of the energy storage housing 1 by spot welding or laser welding. With the above configuration, the first electrode sheet and the second electrode sheet effectively realize the connection with the energy storage housing, and the first electrode sheet and the second electrode sheet not only stably fix the battery in the battery compartment, but also realize series or parallel connection between multiple batteries to form a large-capacity battery pack, endowing the energy storage power source with the functions of energy storage and power supply, and is easy to assemble. It replaces ordinary battery bags available on the market, and eliminates a series of processes such as binding, gluing, filling, blow molding, sealing and decorating multiple batteries, which is environmentally friendly and facilitates automated production, reduces the defect rate of the energy storage power source, and improves production efficiency and safety.

[0028] In this embodiment, the side wall of the battery chamber 11 is further provided with an elastic member 10, and when the battery 21 is inserted into the battery chamber 11 through the first opening 111 or the second opening 112, the elastic member 10 presses and locks the battery in the battery chamber. Specifically, the elastic member 10 is an elastic wall, and both sides of the elastic wall are provided with slots 101. When the battery 21 is inserted into the battery chamber 11 through the first opening 111 or the second opening 112, the elastic wall is pressed by the battery and elastically deformed due to the slots provided on both sides of the elastic wall, and the elastic restoring force generated by the elastic wall being pressed by the battery and elastically deforming presses and locks the battery in the battery chamber. Through the above structure, the design is reasonable, the structure is simple and compact, and the battery can be effectively fixed in the battery chamber, preventing the battery from shaking, and greatly improving the stability and safety of the energy storage power source.

[0029] In this embodiment, the energy storage power supply further includes a front housing 5 and a rear housing 6, the energy storage housing 1 is located between the front housing 5 and the rear housing 6, and when the front housing 5 removably caps the rear housing 6, the front housing 5 is connected to one side of the energy storage housing 1, and the rear housing 6 is connected to the other side of the energy storage housing 1. When the front housing 5 removably caps the rear housing 6, a receiving cavity 7 is formed, and a plurality of battery compartments 11 are located in the receiving cavity 7. With the above configuration, the battery is fixed by the battery chamber, the first electrode sheet, and the second electrode sheet of the energy storage housing, so that fixing of the battery position does not need to be achieved by relying on the assembly between the energy storage housing and the front and rear housings. The cap between the front and rear housings only provides a receiving cavity for receiving the battery chamber, so the requirements for the assembly accuracy between the energy storage housing and the front and rear housings are very low, and the dimensional accuracy of the receiving cavity is also very low, making the assembly simple. Instead of using commercially available battery bags, a series of processes such as binding, gluing, filling, blow molding, sealing, and decorating multiple batteries are eliminated, which is environmentally friendly and facilitates automated production, reduces the defect rate of energy storage power sources, improves production efficiency and safety, and significantly reduces production costs.

[0030] In this embodiment, a plurality of battery compartments 11 are arranged in a honeycomb shape. The plurality of battery compartments 11 are separated from each other by partition plates 113. With the above-mentioned configuration, the plurality of battery compartments arranged in a honeycomb shape are spaced apart from each other by the partition plates, and heat released during battery operation is released to the outside through the energy storage housing and the partition plates, effectively preventing damage and explosion of the batteries due to heat accumulation of the plurality of batteries, greatly improving the heat dissipation and safety of the energy storage power source, and also improving the power supply efficiency and power supply stability of the energy storage power source.

[0031] In this embodiment, the front housing 5 and the rear housing 6 are configured to be removably connected. Specifically, the front housing 5 is provided with a first locking groove 5a, the rear housing 6 is provided with a first locking fastener 6a, and the first locking fastener 6a and the first locking groove 5a are arranged to be removably connected. In another embodiment, the front housing 5 may be provided with a first locking fastener, and the rear housing 6 may be provided with a first locking groove, thereby realizing a removably connection between the two.

[0032] Further, the energy storage power source includes a chamber cover 1014 provided along the longitudinal direction of the first support plate 12 or the second support plate 13. The chamber cover 1014 is arranged to be removably connected to the energy storage housing 1. The chamber cover 1014 is provided with at least two second locking fasteners 1016. The energy storage housing 1 is provided with at least two second locking grooves 1017. The second locking fasteners 1016 and the second locking grooves 1017 are arranged to be removably connected. With the above configuration, the locking fastener structure can facilitate the removal of the chamber cover 1014 from the energy storage housing 1, and the lighting device can be removed and replaced at any time if it is damaged.

[0033] Specifically, the energy storage housing 1 is provided with an illumination chamber 1011. The illumination chamber 1011 is provided with a first light outlet 1012. The energy storage power supply includes an illumination device 57. The illumination device 57 includes a light emitting element 571 and a condenser lens 572. The illumination device 57 is provided in the illumination chamber 1011. The light emitting surface of the light emitting element 571 is provided facing the condenser lens 572 and the first light outlet 1012. The condenser lens 572 is used to polymerize the light emitted by the light emitting element 571 to form a small light beam with a long irradiation distance. The light emitting element may be an LED lamp. With the above configuration, an illumination device is installed in the energy storage power supply, and a condenser lens is installed in front of the light emitting element, so that the action of the polymerization light of the condenser lens can make the energy storage power supply emit a small beam with a long irradiation distance, which can achieve the purpose of a longer irradiation distance and a clearer field of vision when the user uses the energy storage power supply outdoors or in other places, and can greatly improve the practicality and user experience of the energy storage power supply.

[0034] In this embodiment, the condenser lens 572 is a convex lens. Due to the condensing effect of the convex lens itself, the light emitted from the light emitting element is polymerized as it passes through the convex lens to form a small beam, thereby realizing long-distance irradiation.

[0035] In this embodiment, the lighting device 57 further includes a lighting housing 573. The lighting housing 573 is provided with a second light outlet 5731 and a connection part 5732 located at the second light outlet 5731. The first light outlet 1012 is provided with a groove 1013. The bottom surface of the connection part 5732 is connected to the bottom surface of the groove 1013 so that the lighting housing 573 is set in the lighting chamber 1011. The condenser lens 572 is located in front of the connection part 5732 and is located in the groove 1013. With the above configuration, the arrangement position of the condenser lens 572 effectively realizes that the light beam emitted from the light-emitting element passes through the condenser lens 572 and is emitted from the first light outlet 1012 and the second light outlet 5731, thereby achieving the effect of long-distance irradiation.

[0036] In this embodiment, the energy storage housing 1 is provided with a chamber cover 1014. The chamber cover 1014 is connected to the energy storage housing 1 to isolate the illumination housing 573 and the condenser lens 572 within the illumination chamber 1011. The chamber cover 1014 is provided with a light passage hole 1015. The light passage hole 1015 communicates with the first light outlet 1012 and the second light outlet 5731. With the above configuration, the design of the chamber cover 1014 allows the illumination device to be securely attached and secured to the energy storage housing 1 of the energy storage power source, ensuring the safety of the illumination device.

[0037] In this embodiment, the chamber cover 1014 is provided with at least one screw mounting post 1018. The housing 101 is provided with at least one screw hole 1019 that mates with the screw mounting post 1018. A screw is installed through the screw hole 1019 and into the screw mounting post 1018 such that the chamber cover 1014 is fixedly connected to the housing 101. With the above configuration, the connection between the chamber cover 1014 and the housing 101 is stronger and more stable, ensuring the safety of the lighting device.

[0038] Furthermore, the front housing 5 is provided with a third locking groove 5b communicating with one of the second locking grooves 1017.
