Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0040] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms 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.

[0041] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0043] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0044] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0045] See Figures 1 to 4As shown, an embodiment of the electrical equipment provided in this application includes a housing 100 and a cover 300. A receiving cavity 110 is formed in the housing 100, and the receiving cavity 110 has an opening. A connecting part 211 is provided in the receiving cavity 110. The cover 300 is detachably connected to the housing 100. When the cover 300 and the housing 100 are in a connected state, the cover 300 closes the opening of the receiving cavity 110 and covers the connecting part 211. When the cover 300 and the housing 100 are in a separated state, the connecting part 211 can be exposed through the opening of the receiving cavity 110 so as to be detachably connected to the carrying handle 1000.

[0046] When the aforementioned electrical equipment needs to be moved, such as when it needs to be hung on a wall, the cover 300 can be removed, and the carrying handle 1000 can be connected through the connecting part 211 provided in the receiving cavity 110. The operator can hold the carrying handle 1000, thus conveniently hanging the electrical equipment on the wall, making the moving and installation of the electrical equipment more labor-saving and convenient. When moving and installation are not required, by connecting the cover 300 to the housing 100, the connecting part 211 can be covered and the receiving cavity 110 can be sealed, improving the aesthetics of the electrical equipment and reducing the risk of moisture, dust and other foreign objects entering the receiving cavity 110. Since there is no need to set an additional mounting bracket on the cover 300 or the housing 100 to install the carrying handle 1000, not only is the aesthetics of the electrical equipment improved, but the risk of the mounting bracket becoming loose or damaged due to accidental collisions caused by exposed mounting brackets can also be reduced, while avoiding the additional space occupation caused by setting up mounting brackets.

[0047] In a practical application scenario, the electrical device is an energy storage device. Correspondingly, the energy storage device may also include battery modules and power modules such as inverters, rectifiers, and choppers. The housing 100 and cover 300 provide protection for the internal battery modules and power modules. When the energy storage device needs to be mounted on a wall, the cover 300 can be removed, and a carrying handle 1000 can be connected via the connecting part 211 provided in the accommodating cavity 110. The operator can hold the carrying handle 1000, thus easily mounting the energy storage device on the wall, making the transport and installation of the energy storage device more labor-saving and convenient. In other embodiments, the electrical device may also be a wall-mounted distribution box, a wall-mounted uninterruptible power supply, a wall-mounted electricity meter, etc.

[0048] See Figure 2 and Figure 3As shown, in one embodiment, the electrical equipment further includes a heat dissipation module 210 located within the accommodating cavity 110, the heat dissipation module 210 having a connecting portion 211. Understandably, the heat dissipation module 210 is typically one of the more robust components of the electrical equipment; attaching the carrying handle 1000 here provides stronger support for the entire electrical equipment, reducing the impact on internal components during handling. In some embodiments, the heat dissipation module 210 may be a heat sink.

[0049] See Figure 2 and Figure 3 As shown, in one embodiment, the electrical equipment further includes a support member 220, to which the heat dissipation module 210 is connected. The support member 220 mounts the heat dissipation module 210, providing reliable support and ensuring that the heat dissipation module 210 will not loosen or deform during long-term use, further guaranteeing the reliability of the handling handle 1000 connected to the heat dissipation module 210. In some embodiments, the support member 220 is made of sheet metal, which has high mechanical strength and good thermal conductivity, providing solid support for the heat dissipation module 210 and facilitating rapid heat conduction to the heat dissipation module 210, thus improving heat dissipation efficiency.

[0050] See Figure 2 and Figure 3 As shown, in some embodiments, the support member 220 is configured with a through hole 221 for the handling handle 1000 to pass through. By providing the through hole 221 on the support member 220, the number of connection points between the electrical equipment and the handling handle 1000 is further increased, improving the connection reliability between the electrical equipment and the handling handle 1000, and further enhancing the safety during the handling process.

[0051] See Figure 1 and Figure 2 As shown, in one embodiment, the cover 300 is provided with heat dissipation holes 310 communicating with the accommodating cavity 110. By providing heat dissipation holes 310 on the cover 300, airflow between the inside of the device and the external environment can be promoted, improving the heat dissipation effect. Combined with... Figure 5 and Figure 6As shown, in some embodiments, the inner surface of the cover 300 facing the heat dissipation module 210 has a protrusion 400. The protrusion 400 includes a blocking portion 410 and a flow portion 420. The blocking portion 410 is positioned corresponding to the position of the heat dissipation hole 310 to block the heat dissipation hole 310. The flow portion 420 has a flow groove 421 communicating with the heat dissipation hole 310. This design allows the blocking portion 410 to effectively prevent external dust, moisture, or other impurities from directly entering the device through the heat dissipation hole 310, reducing the direct impact of the external environment on the internal electronic components and improving the reliability and durability of the device. The flow groove 421 allows air to still effectively enter and exit the device, maintaining good ventilation and ensuring that the heat inside the device is effectively dissipated. At the same time, the protrusion 400 inside the cover 300 can enhance the local strength of the cover 300 and prevent the cover 300 from deforming due to external pressure or impact.

[0052] See Figure 5 As shown, in one embodiment, the cover 300 is provided with a gripping portion 320 for an operator to grasp. By providing the gripping portion 320 on the cover 300, the operator can easily remove the cover 300 by applying the gripping portion 320, facilitating the connection of the carrying handle 1000. In some embodiments, gripping portions 320 are provided on two sides of the cover 300 along the width direction of the electrical equipment, i.e., the X direction in the figure, and the gripping portions 320 are located near the edge of the cover 300, making it easy for the operator to access the gripping portion 320 and facilitating operation. The gripping portion 320 is designed as a groove to provide a comfortable grip for the operator.

[0053] See Figure 6 and Figure 9 As shown, in one embodiment, the housing 100 is provided with a support block 120. When the cover 300 is connected to the housing 100, the support block 120 supports the cover 300. Supporting the cover 300 with the support block 120 effectively disperses the pressure on the cover 300, further improving its strength, reducing the risk of deformation, helping to maintain sealing performance, preventing dust and moisture from entering the device, and extending its service life. Simultaneously, the stable support provided by the support block 120 helps reduce the impact of external vibrations on internal electronic components, ensuring the stability of device operation. In some embodiments, the support block 120 can be approximately a U-shaped block, which engages with the cover 300 through its opening, thereby providing support for the cover 300. Furthermore, the cover 300 can be provided with a support groove 350, and a portion of the support block 120 can be embedded within the support groove 350, further increasing the contact area between the cover 300 and the housing 100 and improving the support effect. At the same time, it can also help the cover 300 to be accurately aligned with the shell 100 during the assembly process, simplifying the assembly steps and improving production efficiency.

[0054] See Figure 4 As shown, in one embodiment, the electrical equipment further includes a plurality of supports 500 detachably connected to the housing 100, the supports 500 being spaced apart on both sides of the housing 100 along a first direction; each support 500 has a supporting plane. The supporting plane of the supports 500 provides an anti-tipping effect, significantly increasing the stability of the equipment and preventing damage to internal components from accidental tipping. The position or number of supports 500 can be adjusted to suit specific application scenarios, ensuring stability in various working environments. In some embodiments, the supports 500 can be made of high-strength, corrosion-resistant metal materials (such as aluminum alloy or stainless steel) to ensure long-term reliability. Figure 4 As shown, the first direction is the X direction in the diagram. In a practical application scenario, the first direction is the width direction of the electrical equipment. Correspondingly, the length direction of the electrical equipment is the Y direction in the diagram, and the thickness direction of the electrical equipment is the Z direction in the diagram.

[0055] See Figure 5 As shown, in one embodiment, the cover 300 has pre-cut first sealing portions 330 at both ends along a first direction. When the first sealing portions 330 are removed, the cover 300 forms a first clearance hole, through which a portion of the bracket 500 passes. Before installing the bracket 500, the first sealing portions 330 are connected to the cover 300, providing waterproofing and dustproofing while enhancing the aesthetics of the device. When the bracket 500 needs to be installed, the first sealing portions 330 are removed, allowing the first clearance hole to be quickly created without additional processing, adapting to different configurations and improving usability.

[0056] See Figure 8 As shown, in one embodiment, the electrical equipment has a pre-cut second sealing portion 610. When the second sealing portion 610 is removed, the electrical equipment forms a cable passage hole 620. When the equipment is not in use or does not require wiring, the second sealing portion 610 remains in place, ensuring that the inside of the equipment is not affected by dust, moisture, or other contaminants, thereby protecting the internal electronic components. Moreover, the presence of the second sealing portion 610 can increase the overall rigidity of the equipment and reduce the risk of deformation or damage caused by external forces. When it is necessary to connect power lines, signal lines, or other types of cables, the cable passage hole 620 can be formed by removing the second sealing portion 610, facilitating the entry and exit of cables, simplifying the installation process, and making the wiring more organized. Of course, the cable passage hole 620 can not only be used for initial wiring but also facilitates subsequent maintenance and repair work, such as replacing cables or adjusting internal connections.

[0057] See Figure 5As shown, in one embodiment, the cover 300 is pre-cut with a third sealing portion 340. When the third sealing portion 340 is in the removed state, the wire hole 620 is exposed relative to the cover 300. When the third sealing portion 340 is not removed, it maintains the sealing performance of the electrical equipment, preventing dust, moisture, and other contaminants from entering the equipment and protecting the internal electronic components from the influence of the external environment. Furthermore, it enhances the overall strength and rigidity of the equipment casing, reducing the risk of deformation due to external impacts or vibrations.

[0058] See Figure 5 and Figure 8 As shown, in one embodiment, both the second blocking part 610 and the third blocking part 340 are located at one end of the electrical equipment along the first direction, and the second blocking part 610 and the third blocking part 340 are distributed along the first direction. Concentrating the second blocking part 610 and the third blocking part 340 at one end of the equipment makes the cable entry and exit points of the equipment more centralized, which is convenient for management and maintenance; it also helps to reduce the complexity of wiring and make the cable layout more neat and orderly.

[0059] See Figure 8 As shown, in some embodiments, the electrical equipment is provided with a second sealing part 610 at both ends along the first direction. Thus, when the two second sealing parts 610 are removed, both ends of the electrical equipment are provided with wire holes 620, so that the cable can enter and exit from both sides of the electrical equipment. The most suitable cable path can be selected according to actual needs to adapt to different installation environments and layout requirements.

[0060] See Figure 5 As shown, in some embodiments, the electrical equipment is provided with third sealing portions 340 at both ends along the first direction, thereby improving the sealing performance of the electrical equipment. In use, the third sealing portions 340 on the corresponding side can be removed according to the layout requirements, for example, removing one or both third sealing portions 340, to adapt to the actual cable layout requirements.

[0061] See Figure 2 As shown, in one embodiment, the electrical equipment also includes a gland 630 connected to the cable passage 620. The gland 630 securely holds the cable in place at the cable passage 620, preventing it from loosening or falling off due to vibration or external forces; it also disperses tensile and torsional forces on the cable, protecting the internal conductors and extending its lifespan. Understandably, the gland 630 is typically equipped with rubber gaskets or other sealing materials to provide an effective seal when the cable passes through the cable passage 620, preventing moisture, dust, and other contaminants from entering the equipment; it also effectively isolates the electrical contact between the cable and the equipment housing, preventing short circuits and ensuring operator safety.

[0062] See Figure 7 and Figure 10 As shown, in one embodiment, one of the housing 100 and the cover 300 is provided with a first snap-fit ​​360, and the other is provided with a first slot 130 for engaging with the first snap-fit ​​360. Using a snap-fit ​​connection eliminates the need for additional tools (such as screwdrivers, wrenches, etc.) for assembly or disassembly, greatly simplifying the installation process. Compared to screw fastening, snap-fit ​​connections significantly reduce assembly time, improve production efficiency, and reduce the need for screws, nuts, and other fasteners, thereby lowering material costs. The elimination of exposed screw heads or other fasteners results in a cleaner and more aesthetically pleasing product appearance. In some embodiments, the first snap-fit ​​360 has a certain degree of elasticity, which helps to achieve a tight fit between the housing 100 and the cover 300, improving the overall sealing effect. Simultaneously, the elastic first snap-fit ​​360 can also absorb vibration to a certain extent, reducing the risk of parts loosening or being damaged due to vibration.

[0063] See Figure 7 and Figure 10 As shown, in one embodiment, one of the housing 100 and the cover 300 is provided with a second latch 370, and the other is provided with a second slot 140 for engaging with the second latch 370; the engagement direction of the second latch 370 is perpendicular to the engagement direction of the first latch 360. For example, in the embodiment shown in the figure, the engagement direction of the first latch 360 is along the length direction of the device, i.e., the Y direction in the figure, and the engagement direction of the second latch 370 is along the X direction in the figure, i.e., the width direction of the device. Since the engagement direction of the second latch 370 is perpendicular to the engagement direction of the first latch 360, the housing 100 and the cover 300 can be fixed in multiple dimensions, thereby providing a more stable connection; moreover, the multi-directional latch design can effectively prevent the housing 100 and the cover 300 from sliding or misaligning relative to each other during use, which helps to achieve a tighter fit and enhance the sealing effect. Meanwhile, the multi-directional snap-fit ​​design allows stress to be distributed more evenly on the contact surfaces of the housing 100 and the cover 300, avoiding structural damage caused by local stress concentration, thereby enhancing the stability of the electrical equipment.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
