[0038] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0039] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, for the purposes of describing the embodiments of the present application herein.

[0040] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "transverse", "longitudinal" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These terms are mainly intended to better describe the present application and its embodiments, and are not intended to limit the indicated devices, elements or components to having a specific orientation, or to be constructed and operated in a specific orientation. Moreover, in addition to being used to indicate orientations or positional relationships, some of the above terms may also be used to indicate other meanings. For example, the term "upper" may also be used to indicate a certain dependency or connection relationship in certain circumstances. For those of ordinary skill in the art, the specific meanings of these terms in the present application can be understood according to the specific circumstances.

[0041] like Figure 1 As shown, the present application provides a box-type power supply, including a box cover 100 and a box body 200. The box body 200 includes box walls 210 and a bottom plate 220 for placing battery modules. The bottom plate 220 is provided with a plurality of block-shaped support pads 221. The box cover 100 is provided on the top of the box body 200 to close the box body 200.

[0042] Among them, such as Figure 1As shown, the box cover 100 is installed with a stop frame 110, which extends upward along the edge of the box cover 100. With the top surface of the box cover 100 as the projection surface, the projection of the support pad 221 is located inside the projection of the stop frame 110, and the edge parts of the two projections are in contact with each other.

[0043] In this way, multiple box-type power supplies can be stacked on each other. Under the limiting action of the stop frame 110 and the support pad 221, the box-type power supply located on the upper part will not slip, ensuring the safety of operation and not taking up space when stored.

[0044] Since the box-type power supply is usually used outdoors and often faces rain, snow or other harsh environments, the top of the box-type power supply may be damaged due to water accumulation, so it is preferred that Figure 2 As shown, the stop frame 110 is provided with a water diversion groove 111 on the side facing the box cover 100. The water diversion groove 111 can discharge water from the top of the box cover 100, so that the box-type power supply can not only be safely and effectively connected in parallel, but also be more suitable for the application environment and extend the service life of the battery.

[0045] Further, such as Figure 2 As shown, the stop frame 110 is a rectangular tubular structure with a large structural strength and is not easy to hide dust. Specifically, four aluminum alloy moldings can be arranged on the top of the box cover 100 as the stop frame 110.

[0046] As an optional solution, to reduce the user's burden, threaded holes for installing M8 eyebolts are provided at the four corners of the stop frame 110. When multiple box-type power supplies are cascaded, the power boxes can be lifted and assembled in cascade using a mechanical device, saving time and effort. Furthermore, to prevent the effects of dust and moisture in the operating environment on the threads, the threaded holes at the four corners are equipped with silicone plugs to effectively protect the threads from damage.

[0047] Specifically, the height of the stop frame 110 is equal to the height of the support pad 221 . If the support pad 221 is higher, impurities are easily introduced into the stop frame 110 when the support pad 221 cooperates with the stop frame 110 , and the appearance is not good enough.

[0048] Specifically, if Figure 3 As shown, the box-type power supply includes four rectangular support pads 221 , which are respectively arranged at the four corners of the bottom plate 220 .

[0049] Preferably, Figure 3As shown, the box-type power supply further includes a load-bearing block 222, which is located in the space enclosed by the support pads 221, has the same height as the support pads 221, and has a larger bottom area than the support pads 221. This design can distribute the pressure borne by the support pads 221 to the load-bearing block 222, so that the pressure is balanced. When the box-type power supplies are stacked, the box-type power supply located on the lower side is prevented from being subjected to excessive pressure at the support pads 221, effectively preventing localized force from causing the casing to twist, deform, or even crack.

[0050] Preferably, a plurality of slots 2221 are formed at the bottom of the load-bearing block 222, and this design can play a certain anti-slip role. Specifically, some of the slots 2221 are waist-shaped.

[0051] Optionally, the support pad 221 is made of stainless steel to ensure support strength, and the load-bearing block 222 is made of aluminum alloy to make the product lightweight.

[0052] The box body 200 includes a front wall 211, a rear wall 212 and two side walls 213. Figure 4 As shown, the front wall 211 is provided with a cascade socket area 2116, and the lower side of the front wall 211 is provided with a ventilation area 2111, which is used to dissipate heat for the battery. Figure 5 As shown, the rear wall 212 of the box body 200 is provided with an air outlet 2121 , and the air outlet 2121 is used to cooperate with the cooling fan and the ventilation area 2111 in the box body 200 to dissipate heat for the battery module.

[0053] Specifically, such as Figure 4 As shown, the ventilation area 2111 is provided with a ventilation groove 2111a, and the upper side of the ventilation groove 2111a is provided with an opening 2111b. The opening 2111b is parallel to the box cover 100 and is used to communicate with the internal space of the box body 200. This structure can effectively ventilate and dissipate heat while preventing rainwater from entering the opening 2111b as much as possible to cause battery damage.

[0054] In order to further solve the waterproof and dustproof problem of the ventilation area 2111, as a preferred solution, Figure 6 As shown, the bottom plate 220 is provided with a mounting groove 223 on the side near the front wall 211, and the mounting groove 223 extends along the ventilation area 2111. A plurality of ventilation holes are provided on the side of the mounting groove 223 opposite the front wall 211. A dustproof part 223a is removably inserted into the mounting groove 223. The dustproof part 223a covers the ventilation area 2111. When water splashes into the interior of the box from the ventilation area 2111, the dustproof cotton can effectively block the water and avoid causing a short circuit to the electronic components. The dustproof part has good dustproofness and water absorption, and is a consumable part. The user can remove it from the mounting groove 223 and replace it with a new dustproof part to meet the use requirements.

[0055] Specifically, the dustproof member 223a is made of cotton material.

[0056] More specifically, the dustproof member 223a is inserted into the mounting slot 223 through the mounting frame. The mounting frame is a rectangular frame structure and includes a connecting plate 224. The connecting plate 224 is flush with the bottom plate 220. Specifically, the connecting plate 224 is detachably connected to other components of the mounting frame, and the connection method can be bolts, screws, etc.

[0057] Preferably, at least one side of the connecting plate 224 is formed with a notch, which extends along the length of the connecting plate 224. When the dustproof piece absorbs excessive water, the excess water can be smoothly discharged from the notch of the connecting plate 224 at the bottom of the mounting frame.

[0058] In order to solve the above problems, as another preferred solution, Figure 7 As shown, a ventilation cover 2112 is provided inside the housing 200 in the ventilation area 2111. The ventilation cover 2112 and the ventilation area 2111 define a ventilation cavity 2113. The ventilation cover 2112 defines a plurality of ventilation gaps 2112a. Specifically, the ventilation gaps 2112a are smaller than the openings 2111a of the ventilation grooves in the ventilation area 2111. This allows the ventilation cover 2112 to provide ventilation while also preventing rainwater from leaking.

[0059] Furthermore, a water outlet 2114 is opened on the lower side of the ventilation area 2111, and the ventilation cover 2112 covers the water outlet 2114, and the bottom surface of the ventilation cover 2112 extends obliquely upward away from the water outlet 2114, so that the water blocked by the ventilation cover 2112 can flow out of the water outlet 2114, preventing water from accumulating in the ventilation cavity 2113.

[0060] Furthermore, the lowest point of the ventilation cavity 2113 does not exceed the water outlet 2114, so that the water can be fully discharged.

[0061] As a specific solution for box-type power supply, such as Figure 8 As shown, the front wall 211 of the box-type power supply is also provided with a display area 2115, a cascade socket area 2116, and an interface area 2117. The interface area 2117 includes a charging port and various output ports. The display area 2115 should also include a switch, indicator lights, and an information display area. The information display area 2115 includes common indicators such as battery level, number of battery packs, and fault alarms. The indicator lights include charging and discharging indicators and battery health status.

[0062] like Figure 8 The two side walls 213 of the box body 200 are respectively provided with recessed handles 2131 .

[0063] To prevent water from splashing into the box 200 from the sides, as an optional solution, the box 200 is designed with a flange, and silicone sealing gaskets are attached to the bottom surface of the lid around the four sides, so that the box cover 100 fits tightly with the box 200. As another optional solution, the box cover 100 is designed with a bent flange around the four sides, and the flange covers at least a part of the box 200.

[0064] Furthermore, in order to achieve a tight fit between the stop frame 110, the box cover 100 and the box body 200, when the box body 200 is designed with a flange, the screws are passed through the through holes of the stop frame 110 and the box cover 100 and locked with the sealing rivet studs of the box body flange; when the box cover 100 is designed with a flange, the stop frame 110 and the box cover are first fixed with screws, and then the box cover 100 is covered on the box body 200, and locked by screwing screws around. The threaded holes around are all sealed rivet nuts, which can effectively prevent water from entering.

[0065] Preferably, all interfaces on the surface of the box 200 and the handles 2131 on both sides are recessed and do not exceed the surface of the box 200, and each interface and handle 2131 is equipped with a sealing gasket when fixed to prevent dust and water.

[0066] Among them, the battery module inside the box-type power supply is a split assembly design, and single or multiple battery modules can be replaced at will, which is convenient and quick.

[0067] Specifically, the replaceable and detachable battery module is composed of a shell, a battery handle, a wire protection sleeve, an insulating sheet, a battery body, etc. The battery module and the box body 200 can be fixed by screws.

[0068] In detail, Figure 9 As shown, the box-type power supplies in this embodiment can be used in cascade mode, stacked one on top of the other to increase capacity. Each box-type power supply has two cascade sockets, A and B. A matching cable connects the A cascade port on one energy storage power supply box to the B cascade port on another. Furthermore, this box-type power supply offers superior structural strength, as well as waterproof and dustproof properties, meeting user needs for outdoor use.

[0069] In this application, the terms "installed," "disposed," "provided with," "connected," "connected," and "socketed" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0070] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
