[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0040] In the description of this application, it should be understood that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application. In the description of this application, "multiple" means two or more, and "at least one" can refer to one, two, or more, unless otherwise explicitly specified. The terms "first," "second," and "third," etc., are only for the convenience of description and are used to name components or embodiments by number, and do not imply any order of importance between the components or embodiments.

[0041] It should also be noted that in the accompanying drawings of this application, the arrow marked X indicates the first direction X, and the arrow marked Y indicates the second direction Y. The introduction of the first direction X and the second direction Y in the description of this application is to more clearly define the structure and relative positional relationships of the components in the electrical equipment. In actual implementation, the first direction X is generally a vertical direction or the height direction, and the second direction Y is generally a horizontal direction. The first direction X and the second direction Y are perpendicular to each other to optimize the layout of the electrical equipment. In the description of this application, "perpendicular" means completely perpendicular to 90° or almost completely perpendicular; for example, an angle between 80° and 100° is considered perpendicular.

[0042] As an introduction to this application, with the rapid development of the new energy industry, electrical equipment has become a core device for energy storage and dispatch. Its power output line is responsible for energy transmission, and its communication output line ensures data interaction. The connector terminals at the interface of these two devices require protective shields to prevent dust, moisture intrusion, and accidental contact by personnel. However, the independent protective shield design used in related technologies requires disassembly of the protective shield before maintenance or repair, resulting in low maintenance efficiency. After maintenance or repair, it is easy to forget to install the shield, leaving the connector terminals directly exposed. This not only makes them susceptible to environmental corrosion, shortening the equipment's lifespan, but also poses safety hazards. The above design does not fully meet the long-term operating requirements of the equipment. The protective shield is not integrated with the electrical equipment, lacks a stable connection, and is prone to falling off under long-term vibration or external force. Furthermore, there is no mechanism to prevent unauthorized disassembly, and the protective function is easily rendered ineffective by human disassembly.

[0043] In view of the above, embodiments of this application provide an electrical device aimed at solving at least one of the aforementioned technical problems.

[0044] Please see Figure 1 and Figure 2As shown, the electrical equipment disclosed in this application includes a cabinet 10 and a protective cover 20. At least one side of the cabinet 10 has a wiring area 100, and the cabinet 10 is provided with a first connector 11. The protective cover 20 is provided with a second connector 21. One of the second connector 21 and the first connector 11 is provided with a first guide groove 211, and the other is provided with a fixed shaft 111. The first guide groove 211 extends along the extending direction of the first connector 11, and the fixed shaft 111 passes through the first guide groove 211 and forms a sliding fit. The second connector 21 is rotatable relative to the first connector 11. It should be understood that the protective cover 20 is movable relative to the cabinet 10 between a locked position a and an unlocked position b. When the protective cover 20 is in the locked position a, the protective cover 20 covers the wiring area 100. When the protective cover 20 is in the unlocked position b, the protective cover 20 is allowed to flip relative to the cabinet 10 to open the wiring area 100. The protective cover 20 is movably connected to the cabinet 10 via the first connector 11 and the second connector 21, ensuring that the protective cover 20 remains connected to the cabinet 10 at all times. This integrates the protective cover 20 into the overall structure of the electrical equipment, rather than as an independent additional component. During maintenance, the protective cover 20 only needs to be moved to the unlocked position b. In the unlocked position b, the protective cover 20 simply needs to be flipped relative to the cabinet 10 to open the wiring area 100. There is no need for complete disassembly, handling, or storage of the cover, significantly simplifying maintenance procedures and improving repair efficiency. After maintenance, the flipped protective cover 20 only needs to be returned to the locked position a, further improving maintenance efficiency, preventing corrosion of terminals by environmental dust / moisture, and eliminating the safety hazard of accidental contact by personnel, indirectly extending the equipment's service life.

[0045] It is important to understand that when the protective cover 20 is in the unlocked position b, it flips relative to the cabinet 10, and there must be no structural interference between the protective cover 20 and the cabinet 10. The protective cover 20 can be a single-sided or multi-sided protective structure. When the protective cover 20 is a single-sided protection structure, the cabinet 10 forms a cavity on the side where the protective cover 20 is located, and the wiring equipment is installed in the cavity. When the protective cover 20 is in the locked position a, it can cover the cavity to protect the wiring equipment. When the protective cover 20 is a multi-sided protection structure, it forms a covered space to protect the wiring equipment.

[0046] Please see Figure 3 and Figure 4As shown, in some embodiments, the first connector 11 and the second connector 21 form a sliding engagement, and the second connector 21 can rotate relative to the first connector 11. It should be understood that the sliding engagement between the protective cover 20 and the cabinet 10, via the first connector 11 and the second connector 21, allows switching between the locked position a and the unlocked position b of the protective cover 20; the relative rotational engagement between the first connector 11 and the second connector 21 allows the protective cover 20 to flip relative to the cabinet 10. In the above design, the sliding and rotational engagement method makes the driving method of the protective cover 20 simple and reliable, and provides better stability and flexibility. If complex operations such as wiring or replacing terminals are required, only one hand needs to push the protective cover 20 to slide relative to the cabinet 10, and then flip the protective cover 20 at a certain angle, freeing up both hands and improving operational efficiency.

[0047] Please see Figure 3 and Figure 4 As shown, in some embodiments, one of the second connector 21 and the first connector 11 is provided with a first guide groove 211, and the other is provided with a fixed shaft 111. The fixed shaft 111 passes through the first guide groove 211 and forms a sliding fit. When the protective cover 20 is in the unlocked position b, the second connector 21 can rotate relative to the first connector 11 with the fixed shaft 111 as the rotation center. It should be understood that the cooperation structure between the first connector 11 and the second connector 21 is simple and reliable. By sliding the fixed shaft 111 along the first guide groove 211, the locking position a and the unlocked position b of the protective cover 20 can be switched. By abutting one end of the first guide groove 211 with the fixed shaft 111, the protective cover 20 is pulled away from the cabinet 10, so that the second connector 21 rotates relative to the first connector 11 with the fixed shaft 111 as the rotation center, thereby exposing the wiring area 100 to provide maintenance operation space. The above-mentioned driving method is stable and reliable. While ensuring the connection between the protective cover 20 and the cabinet 10, it can realize the operation and maintenance of the wiring area 100, thus improving the operational efficiency.

[0048] Please see Figure 6 and Figure 7 As shown, in some embodiments, the second connector 21 is provided with a first guide groove 211, and the first connector 11 is provided with a fixed shaft 111. The first guide groove 211 is arranged along the height direction. When the protective cover 20 is in the locked position a, the top contour of the first guide groove 211 contacts the fixed shaft 111, and the protective cover 20 is hung on the fixed shaft 111 under the action of gravity, achieving self-locking. In some embodiments, the first connector 11 is provided with a first guide groove 211, and the second connector 21 is provided with a fixed shaft 111. The first guide groove 211 is arranged along the height direction. When the protective cover 20 is in the locked position a, the bottom contour of the first guide groove 211 contacts the fixed shaft 111, with the same effect as above, which will not be described again.

[0049] Please see Figure 3 and Figure 4 As shown, in some embodiments, one of the first connector 11 and the second connector 21 is provided with a second guide groove 212, and the other is provided with a slider 112. One end of the second guide groove 212 has a notch 2120, and the slider 112 passes through the second guide groove 212 and forms a sliding fit. When the protective cover 20 is in the unlocked position b, the slider 112 can disengage from the second guide groove 212 through the notch 2120. It should be understood that the second guide groove 212 provides a sliding path for the slider 112, allowing the protective cover 20 to slide relative to the cabinet 10 by applying a pushing force or relying on its own weight. When the protective cover 20 is in the unlocked position b, the slider 112 and the notch 2120 are opposite each other. By actively applying an external pulling force, the slider 112 disengages from the second guide groove 212 through the notch 2120, and at the same time, the protective cover 20 flips outward relative to the cabinet 10. The above operation method achieves rapid opening of the protective cover 20 in two steps, which can reduce the risk of the wiring area 100 being exposed due to accidental contact with the protective cover 20.

[0050] It is also important to understand that when the protective cover 20 is in the locked position a, the slider 112 is located at the end of the second guide groove 212 away from the notch 2120. By setting the cooperation method between the first guide groove 211 and the fixed shaft 111, and the cooperation method between the second guide groove 212 and the slider 112, the protective cover 20 is relatively locked to the cabinet 10, and the protective cover 20 cannot rotate relative to the cabinet 10, thereby avoiding the risk of exposure of the wiring area 100.

[0051] Please see Figure 7 As shown, in some embodiments, the second connector 21 is provided with a first guide groove 211 and a second guide groove 212, and the first connector 11 is provided with a fixed shaft 111 and a slider 112. The first guide groove 211 and the second guide groove 212 are arranged along the height direction. When the protective cover 20 is in the locked position a, the top contour of the first guide groove 211 contacts the fixed shaft 111, and the top contour of the second guide groove 212 contacts the slider 112. Under the action of gravity, the protective cover 20 is hung on the fixed shaft 111 and the slider 112 as a whole, realizing self-locking. The fixed shaft 111 and the slider 112 can play a stable support role. Without the need to set an additional limiting structure, the stability of the protective cover 20 can be guaranteed.

[0052] Please see Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, in some embodiments, the first guide groove 211 and the second guide groove 212 are both disposed on the first connector 11 or the second connector 21, and are spaced apart along the sliding direction of the fixed shaft 111. It should be understood that by integrating the first guide groove 211 and the second guide groove 212 onto the same connector, they can be formed in a single processing step, ensuring uniform processing accuracy; at the same time, it reduces assembly difficulty and ensures that the connection between the first connector 11 and the second connector 21 is subjected to uniform force.

[0053] Please see Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, the first guide groove 211 is a waist-shaped groove, and the second guide groove 212 is an L-shaped groove.

[0054] Please see Figure 7 As shown, in some embodiments, the first guide groove 211 has a minimum distance D from the second guide groove 212 at its end away from the second guide groove 212, and the fixed shaft 111 has a minimum distance d from the slider 112 at its end away from the slider 112, satisfying: d ≥ D. It should be understood that when d equals D, the fixed shaft 111 abuts against the top of the first guide groove 211, and the slider 112 abuts against the top of the second guide groove 212, allowing one of the first connecting member 11 and the second connecting member 21 to be held on the other, resulting in a stable structure.

[0055] Please see Figure 5 and Figure 6 As shown, in some embodiments, one of the protective cover 20 and the cabinet 10 is provided with a locking part 213, and the other is provided with a mating part 113; when the protective cover 20 is in the locked position a, the locking part 213 and the mating part 113 are detachably connected. It should be understood that by providing the locking part 213 and the mating part 113, the first connecting member 11 and the second connecting member 21 are forcibly locked, reducing the risk of the protective cover 20 being unlocked due to vibration or accidental contact, and reducing accidental interference from external factors. In some embodiments, the locking part 213 and the mating part 113 can be in the form of magnetic attraction, pin, or snap-fit.

[0056] Please see Figure 5 As shown, in some embodiments, the locking part 213 includes a support leg 214, and the mating part 113 includes a fixing pin 114. The support leg 214 has an assembly hole 2140. When the protective cover 20 is in the unlocked position b, the support leg 214 is fitted onto the fixing pin 114 through the assembly hole 2140 to lock the protective cover 20. It should be understood that by fixing the support leg 214 to the fixing pin 114, the movement of the protective cover 20 can be restricted, and the support leg 214 can support the protective cover 20 to improve its stability.

[0057] Please see Figure 5 As shown, in some embodiments, the second connector 21 is provided with a first guide groove 211 and a second guide groove 212, and the first connector 11 is provided with a fixed shaft 111 and a slider 112. The first guide groove 211 and the second guide groove 212 are arranged along the height direction. When the protective cover 20 is in the locked position a, the bottom contour of the first guide groove 211 contacts the fixed shaft 111, and the bottom contour of the second guide groove 212 contacts the slider 112. In this solution, the protective cover 20 needs to be supported by the support leg 214 to ensure that the protective cover 20 will not slip to the unlocked position b under gravity. When it is necessary to open the wiring area 100, by breaking the connection between the support leg 214 and the fixed pin 114, the protective cover 20 can automatically slide to the unlocked position b under the action of gravity. By applying external force to flip the protective cover 20, the wiring area 100 can be exposed. The above design makes opening the protective cover 20 time-saving, labor-saving, and simple to operate.

[0058] Please see Figure 6 As shown, in some embodiments, the locking part 213 includes a locking tongue 215, and the mating part 113 includes a fixing seat 115, which has a limiting space 116. When the protective cover 20 is in the unlocked position b, the locking tongue 215 is received within the limiting space 116 to lock the protective cover 20. It should be understood that the limiting engagement between the locking tongue 215 and the fixing seat 115 allows the protective cover 20 to be limited to the locked position a, preventing the protective cover 20 from opening during non-maintenance periods due to external forces, thus improving safety. When it is necessary to open the wiring area 100, if the first guide groove 211 is arranged along the height direction, it is only necessary to actively push the protective cover 20 upward to the unlocked position b, and then actively flip the protective cover 20.

[0059] Please see Figure 5 and Figure 6 As shown, the cabinet 10 is equipped with protective covers 20 on both sides of the second direction Y.

[0060] In some embodiments, the first connector 11 and the cabinet 10 are integrally formed, and / or the second connector 21 and the protective cover 20 are integrally formed. It should be understood that the integrally formed connectors and the main body (cabinet 10 / protective cover 20) are made of the same material and have the same stress, with no splicing interface, improving vibration resistance and preventing connector detachment. When the protective cover 20 is subjected to unexpected external forces, such as being hit by a heavy object or struck by a tool, the integral structure can disperse the external force to the entire main body (cabinet 10 / protective cover 20) rather than concentrating it at local connection points, enhancing resistance to external impacts and reducing structural deformation. Furthermore, the integral structure simplifies the production and assembly process, reduces costs, and improves mass production efficiency.

[0061] Please see Figure 1 , Figure 2, Figure 3 , Figure 4 As shown, in some embodiments, the protective cover 20 is provided with a weak portion 22, which is configured to be openable to form a wiring notch on the protective cover 20. By providing the weak portion 22 on the protective cover 20 to form a wiring notch, it is convenient to install a cable tray on the protective cover 20 later.

[0062] Please see Figure 2 As shown, in some embodiments, the protective cover 20 can slide relative to the cabinet 10 along the first direction X; there are two of each of the first connector 11 and the second connector 21, and they are spaced apart on both sides of the wiring area 100 along the second direction Y, which intersects with the first direction X. It should be understood that the two sets of connectors symmetrically arranged on both sides form a two-way spatial constraint, completely solving the torsion / displacement problem when the protective cover 20 slides. By having the two sets of connectors work together to distribute the load, fault redundancy is provided, structural reliability is improved, protection failure caused by a single point of failure is avoided, and structural reliability and lifespan are extended.
