Description

Technical Field

[0001] This utility model relates to the field of energy storage high-voltage box technology, and more specifically, to a safe grounded energy storage high-voltage box and energy storage system. Background Technology

[0002] A high-voltage energy storage box is an electrical device that stores large amounts of electrical energy in the form of high voltage and releases it when needed. During the installation of the high-voltage energy storage box, grounding is required to ensure not only its stable operation but also the safety of personnel and equipment.

[0003] In the existing technology, the energy storage high voltage box and battery rack are assembled using a detachable mounting lug method. At the same time, both the mounting lug and the outer shell of the box are sheet metal parts, which need to be coated to meet the anti-corrosion requirements. Therefore, the energy storage high voltage box needs to be coated and masked to ensure that the external assembly of the high voltage box with the battery rack and the internal assembly of electrical components are functionally grounded and conductive.

[0004] However, the existing high-voltage energy storage boxes have the following disadvantages when using spray coating for masking: 1. There are many areas to be masked, which requires manual work such as applying adhesive, peeling off the powder coating after it is applied, and applying conductive paint. This results in high labor intensity. 2. It is difficult to control the thickness of the powder coating manually. Uneven powder coating thickness can lead to electrical conductivity failure, especially in the double-sided conductive contact area between the box body and the mounting ears.

[0005] In summary, how to reduce the contact between the mounting ears and the enclosure during the spraying and masking process, while improving the reliability of grounding and conductivity between the enclosure and the mounting ears, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a safe grounded energy storage high-voltage box, which can improve the convenience of grounding and shielding treatment of the mounting ears and the box body, reduce manufacturing labor costs, and improve the reliability of grounding conduction between the box body and the mounting ears.

[0007] Another objective of this invention is to provide an energy storage system including the aforementioned safe grounded energy storage high-voltage box.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A safe grounded energy storage high-voltage box includes a box body and a mounting lug. The side wall of the box body is provided with a box body grounding hole. The first end of the mounting lug is provided on the side wall of the box body, and the second end is used to connect with the battery rack. The first end of the mounting lug is provided with a grounding fastener that is inserted into the grounding hole of the box body. The grounding fastener is used to make a conductive connection with the earth.

[0011] Preferably, the first end of the hanging ear is detachably mounted on the housing via a set of fasteners, and the grounding fastener is located above the set of fasteners.

[0012] Preferably, there are two hanging ears, which are symmetrically arranged on opposite side walls of the box.

[0013] Preferably, the first end of the hook is provided with a hook grounding hole that is directly opposite to the grounding hole of the enclosure, and the grounding fastener passes through the hook grounding hole and is inserted into the grounding hole of the enclosure.

[0014] Preferably, the first end and the second end of the hook are integrally formed into an L-shaped structure, the first end of the hook is provided with a hook grounding hole, and the second end of the hook is provided on the box body and partially extends out of the side wall of the box body.

[0015] Preferably, the protruding portion of the second end of the hook has at least two battery rack mounting holes along the thickness direction of the housing.

[0016] Preferably, the second end of the loop has an extension opposite to the first end on the side away from its first end, and the length of the extension is less than the length of the first end.

[0017] Preferably, the hanging ears are detachably mounted on the box body on both sides along the thickness direction of the box body via a set of fasteners.

[0018] Preferably, the loop is provided with a handle structure.

[0019] Preferably, the handle structure includes a handle and two connecting plates. The handle is U-shaped. The two connecting plates are respectively disposed on the two side walls of the handle opening end. The two connecting plates and two sets of fasteners are arranged in a one-to-one correspondence.

[0020] Preferably, the two connecting plates are symmetrically arranged along the thickness direction of the box body, the handle is connected between the middle of the two connecting plates, and the two sets of fasteners are symmetrically arranged with the handle as the center.

[0021] Preferably, there are two hanging ears, which are symmetrically arranged on the same side wall of the box.

[0022] An energy storage system, comprising:

[0023] Battery holder;

[0024] The safe grounded energy storage high-voltage box described in any of the above items is located on the battery rack.

[0025] This utility model provides a safe grounded energy storage high-voltage box with conductive grounding fasteners on the mounting ears and grounding holes on the box body. The grounding fasteners are inserted into the grounding holes and can be electrically connected to the earth via a grounding wire, thus achieving grounding conductivity between the box body and the mounting ears. Therefore, the mounting ears and the box body share a single grounding fastener for grounding conductivity. Before assembly, when performing masking spraying, only adhesive tape needs to be applied to the inner side of the box body, the mating area of ​​the grounding fastener, and the contact area between the mounting ears and the battery rack. This reduces the need for masking spraying between the mounting ears and the box body, improves the convenience of grounding masking spraying, lowers manufacturing labor costs, and simultaneously improves the reliability of grounding conductivity between the box body and the mounting ears.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] The core of this utility model is to provide a safe grounded energy storage high-voltage box. This safe grounded energy storage high-voltage box can improve the convenience of grounding and shielding treatment of the mounting ears and the box body, reduce manufacturing labor costs, and at the same time improve the reliability of grounding conduction between the box body and the mounting ears.

[0036] Another core aspect of this invention is to provide an energy storage system that includes the aforementioned safe grounded energy storage high-voltage box.

[0037] Please refer to Figures 1 to 5 This application provides a safe grounded energy storage high voltage box, including a box body 1 and a hanging ear 2. The side wall of the box body 1 is provided with a box body grounding hole 3. The first end 21 of the hanging ear 2 is provided on the side wall of the box body 1, and the second end 22 is used to connect with the battery rack. The first end 21 of the hanging ear 2 is provided with a grounding fastener 5 inserted into the box body grounding hole 3. The grounding fastener 5 is used to conduct electricity to the ground.

[0038] It should be noted that the interior of enclosure 1 is equipped with an electrical vertical plate, on which various electrical components are mounted. To ensure the grounding of these components, the electrical vertical plate is equipped with grounding points that are electrically connected to both the components and enclosure 1. Enclosure 1 is then grounded externally, thus grounding the internal components. Furthermore, the external mounting ears 2 and battery rack of enclosure 1 must also be grounded to enclosure 1.

[0039] Specifically, both the outer shell of the enclosure 1 and the hanging ears 2 are made of metal to ensure grounding conductivity between the enclosure 1 and the hanging ears 2. A grounding hole 3 is provided on the side wall of the enclosure 1, and the hanging ears 2 are mounted on the side wall of the enclosure 1. Preferably, the hanging ears 2 are detachably connected to the enclosure 1 for easy assembly and disassembly. Furthermore, the second end 22 of the hanging ears 2 can be fastened to the battery rack using fasteners such as bolts. The hanging ears 2 serve to assemble the enclosure 1 and the battery rack. A grounding fastener 5 is provided on the first end 21 of the hanging ears 2, inserted into the grounding hole 3 of the enclosure. The grounding fastener 5 is a conductive metal component, such as a bolt, to achieve electrical conductivity between the enclosure 1 and the hanging ears 2. Moreover, the grounding fastener 5 can be electrically connected to the earth via a grounding wire, thereby achieving grounding conductivity between the enclosure 1 and the hanging ears 2.

[0040] When the aforementioned safety-grounded energy storage high-voltage box is being masked during spraying, if... Figure 2 and Figure 3 As shown, only two masking positions Z need to be applied for spraying: the inner side of the housing 1, the mating area of ​​the grounding fastener 5, and the contact area between the back of the hanging ear 2 and the battery rack. This reduces the masking process between the hanging ear 2 and the housing 1. On the one hand, it improves the convenience of grounding masking treatment of the hanging ear 2 and the housing 1 and reduces manufacturing labor costs. On the other hand, it avoids the problem of easy failure of electrical conduction caused by applying conductive paint to the two contact surfaces of the hanging ear 2 and the housing 1, thus improving the reliability of grounding conduction between the housing 1 and the hanging ear 2.

[0041] In the first embodiment, please refer to Figure 1 There are two hanging ears 2, which are symmetrically arranged on the opposite side walls of the box body 1.

[0042] Specifically, two mounting ears 2 are symmetrically arranged on the left and right sides of the enclosure 1 along its width. This serves two purposes: firstly, the two symmetrical mounting ears 2 securely mount the enclosure 1 onto the mounting bracket, ensuring a firm fit between the enclosure 1 and the battery rack, thus improving the structural stability of the enclosure 1; secondly, it prevents the mounting ears 2 from occupying the front wall of the enclosure 1, allowing sufficient area on the front wall for various interfaces, switches, and markings.

[0043] Considering the specific structure of the loop 2, please refer to the first embodiment described above. Figure 2 The first end 21 and the second end 22 of the lug 2 are integrally formed to form a right-angle structure. That is to say, the lug 2 is a right-angle profile with an L-shaped cross-section. This structure has high strength and good stability, which can further improve the stability of the box 1 structure.

[0044] Considering the specific connection method between the hook 2 and the housing 1, please refer to the above first embodiment. Figure 2 The first end 21 of the hanging ear 2 can be detachably mounted on the housing 1 via a set of fasteners 8, and the grounding fastener 5 is located above the set of fasteners 8.

[0045] Specifically, the first end 21 of the lug 2 has a row of mounting holes, and correspondingly, the housing 1 also has a row of mounting holes. The number of fasteners 8 in a set of fasteners 8 is the same as the number of mounting holes in the row. Each fastener 8 is inserted into the mounting holes of the lug 2 and the housing 1 in sequence to achieve a detachable connection between the lug 2 and the housing 1, which facilitates the assembly of the lug 2 and the housing 1 by personnel. In addition, a grounding fastener 5 is integrally provided on the first end 21 of the lug. The grounding fastener 5 is located above the uppermost mounting hole. Correspondingly, the housing grounding hole 3 is also located above the uppermost mounting hole, which facilitates the identification of grounding continuity by personnel.

[0046] Considering the specific connection method between the ear loop 2 and the battery holder, please refer to the above first embodiment. Figure 1 The second end 22 of the hanging ear 2 is provided with at least two battery rack mounting holes 9 along the thickness direction of the housing 1. Thus, it can be installed on the battery rack using fasteners such as bolts, and the hanging ear 2 and the battery rack can be detachably connected, so as to ensure that the hanging ear 2 and the battery rack are securely connected while facilitating the installation and removal of the hanging ear 2.

[0047] To facilitate the movement of the high-voltage energy storage box, please refer to the following based on the first embodiment described above. Figure 1 The housing 1 is equipped with a handle structure 7. This allows for easy lifting or moving of the housing 1 by a person using the handle structure to apply force.

[0048] In the second embodiment, please refer to Figures 3 to 5 Two hanging ears 2 are provided, and the two hanging ears 2 are symmetrically arranged on the same side wall of the box body 1.

[0049] Specifically, the two hanging ears 2 are symmetrically arranged on the front side wall of the box 1 along the width direction. Alternatively, the two ends of the box 1 can be installed on the battery rack, thereby ensuring that the box 1 and the battery rack are firmly assembled and improving the stability of the box 1 structure.

[0050] Considering the specific design of the ear loop 2, please refer to the second embodiment described above. Figure 3 and Figure 4 The first end 21 of the hanging ear 2 is provided with a hanging ear grounding hole 4 that is directly opposite to the grounding hole 3 of the box body. The grounding fastener 5 passes through the hanging ear grounding hole 4 and is inserted into the grounding hole 3 of the box body.

[0051] Therefore, the grounding fastener 5 and the hanging ear 2 are not integrated. A grounding hole 4 is provided on the first end of the hanging ear 2, which is directly opposite and connected to the housing grounding hole 3. This allows the grounding fastener 5 to be sequentially inserted through the hanging ear grounding hole 4 and the housing grounding hole 3, achieving electrical conductivity between the housing 1 and the hanging ear 2. Furthermore, the grounding fastener 5 is connected to the earth via a grounding wire, thus achieving grounding conductivity between the housing 1 and the hanging ear 2. This structure is used during spray painting and masking processes, such as... Figure 4 As shown, after applying tape to the inner side of the housing 1, the mating area of ​​the grounding fastener 5, and the contact area between the back of the hanging ear 2 and the battery rack, tape is then applied to the grounding hole 4 on the front of the hanging ear 2. Even with three spray masking positions Z, the spraying treatment of the two contact surfaces between the hanging ear 2 and the housing 1 can be avoided.

[0052] Therefore, by adopting the above-mentioned hanging ear 2 setting method, the grounding fastener 5 and the hanging ear 2 are detachable, and the pre-tightening force of the grounding fastener can be adjusted to improve the firmness and convenience of installation. At the same time, it improves the convenience of grounding shielding treatment between the hanging ear 2 and the box 1, and improves the reliability of grounding conduction between the box 1 and the hanging ear 2.

[0053] Considering the specific structure of the loop 2, please refer to the second embodiment described above. Figure 3 The first end 21 and the second end 22 of the hanging ear 2 are integrally formed into an L-shaped structure. The first end 21 of the hanging ear 2 is provided with a hanging ear grounding hole 4, and the second end 22 of the hanging ear 2 is provided on the box body 1 and partially extends out of the side wall of the box body 1.

[0054] Specifically, the hanging ears adopt an L-shaped structure, and the grounding hole 4 of the hanging ears is located on the first end 21. The end of the second end 22, away from the first end 21, extends out of the side wall of the housing 1 for connecting the battery rack. Thus, during the assembly process, the L-shaped hanging ears 2 can play a foolproof role, making it easy to identify the corresponding hanging ears 2 at both ends of the housing 1 and the side wall.

[0055] Considering the specific connection method between the ear loop 2 and the battery holder, please refer to the following based on the second embodiment described above. Figure 3 The extended portion of the second end 22 of the hanging ear 2 is provided with at least two battery rack mounting holes 9 along the thickness direction of the housing 1.

[0056] Therefore, fasteners such as bolts can be used to install the battery rack, and the hanging ear 2 can be detachably connected to the battery rack, so as to ensure that the hanging ear 2 is securely connected to the battery rack while making it easy to install and remove the hanging ear 2.

[0057] To further optimize the structure of the loop 2, please refer to the second embodiment described above. Figure 3 The second end 22 of the loop 2 has an extension 23 opposite to the first end 21 on the side away from its first end 21, and the length of the extension 23 is less than the length of the first end 21.

[0058] Specifically, the second end 22 extends in a direction parallel to the first end 21 on the side away from its first end 21 to form an extension 23 opposite to the second end 22, and the length of the extension 23 is less than the length of the first end 21 in the width direction of the housing 1, so that the extension 23, the second end 22 and the first end 21 form a U-shaped structure with a shorter upper side.

[0059] Understandably, the U-shaped structure is characterized by its simple structure, lightweight, and high load-bearing capacity. It saves installation space while maximizing the contact area between the mounting lugs 2 and the housing 1, firmly connecting the housing 1 and the battery rack, thus improving the stability of the energy storage high-voltage box structure. It should be noted that the closed end of the U-shaped structure is the protruding portion of the second end 22 mentioned above, used to connect the battery rack. Furthermore, since the length of the extension 23 in the width direction of the housing 1 is less than the length of the first end 21, the upper part of the U-shaped structure is shorter than its lower part. This allows the lower part of the U-shaped structure to be designed with a grounding hole to achieve grounding conductivity and also better prevents mistaken identification.

[0060] Considering the specific connection method between the hook 2 and the housing 1, please refer to the following based on the second embodiment described above. Figure 3 The hanging ears 2 are detachably mounted to the housing 1 on both sides along the thickness direction of the housing 1 using a set of fasteners 8. In this way, the hanging ears 2 and the housing 1 can be detachably connected by a set of fasteners 8, which is convenient for assembly. Of course, the hanging ears 2 can also adopt a hanging ear structure with a bayonet spring, which can also achieve a detachable connection with the housing 1.

[0061] Specifically, such as Figure 4 As shown, the upper and lower sides of the U-shaped structure each have a set of mounting holes. Correspondingly, the side wall of the housing 1 also has a set of mounting holes at the positions corresponding to the upper and lower sides of the U-shaped structure. Thus, the mounting holes of the U-shaped structure and the corresponding mounting holes of the housing 1 are connected by fasteners 8, thereby achieving a secure connection between the hanging ear 2 and the housing 1. Furthermore, preferably, the two sets of fasteners 8 are symmetrically arranged along the thickness direction of the housing 1, which further ensures a tight connection between the hanging ear 2 and the housing 1. Preferably, each set of fasteners 8 includes at least two fasteners 8, which further helps to ensure a tight connection between the hanging ear 2 and the housing 1.

[0062] To facilitate the movement of the high-voltage energy storage box, please refer to the second embodiment described above. Figure 3 The hanging ear 2 is equipped with a handle structure 7. This allows for easy lifting or moving of the housing 1 by a person using the handle structure, thus facilitating the movement of the energy storage high-voltage box. Furthermore, it avoids the handle structure 7 occupying additional external space of the housing 1, saving installation space.

[0063] Considering the specific design of the handle structure 7, please refer to the following based on the second embodiment described above. Figure 3 The handle structure 7 includes a handle 71 and two connecting plates 72. The handle 71 is U-shaped. The two connecting plates 72 are respectively located on the two side walls of the open end of the handle 71. The two connecting plates 72 and two sets of fasteners 8 are arranged in a one-to-one correspondence. One set of fasteners 8 passes through the connecting plate 72 and the hanging ear 2 and is located on the box body 1.

[0064] The U-shaped handle 71 is ergonomically designed for easy and comfortable gripping. Additionally, connecting plates 72 are attached to both sides of the open end of the handle 71. These connecting plates 72 are detachably mounted on the lugs 2 (i.e., the U-shaped structure). Specifically, each connecting plate 72 has a set of mounting holes, corresponding to the mounting holes in the U-shaped structure and the housing 1. This allows fasteners 8 to pass through the connecting plates 72 and the side mounting holes and be inserted into the mounting holes in the housing 1, enabling a detachable connection between the handle structure 7 and the housing 1 for easy assembly and disassembly of the handle structure 7.

[0065] Further optimize the handle structure 7. Based on the second embodiment described above, please refer to... Figure 3 Two connecting plates 72 are symmetrically arranged along the thickness direction of the housing 1, and a handle 71 is connected between the middle of the two connecting plates 72. Both sets of fasteners 8 are symmetrically arranged with the handle 71 as the center. By adopting the above-mentioned handle structure 7, the force can be effectively distributed and balanced, making the overall structure more robust.

[0066] This utility model also provides an energy storage system, including a battery rack and a safety-grounded high-voltage energy storage box disclosed in the above embodiments, wherein the safety-grounded high-voltage energy storage box is disposed on the battery rack. The structure of other parts of this energy storage system is described in the prior art and will not be repeated here.

[0067] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0068] The above provides a detailed description of the safe grounded energy storage high-voltage box and energy storage system provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
