[0001] The present application relates to the field of energy storage technology, and in particular to a control box. Background Art

[0002] The current energy storage high-voltage control box has limited space and many components are installed inside. The components are generally installed one by one in the control box. When installing components, there is only one installation port and it is restricted by the side of the control box, leaving very limited operating space for installers or maintenance personnel, which makes it time-consuming and laborious to install components in the control box. In addition, the wiring harness in the control box is generally fixed by a wire trough. This method of restraining the wiring harness is time-consuming, and the existence of the wire trough occupies the precious space in the control box, which increases the difficulty of installing components to a certain extent. Utility Model Content

[0003] In order to solve the above problems, the present application provides a control box with ingenious design and simple structure. By providing a detachable lining plate, components can be pre-installed on the lining plate, and then the lining plate and the components on the lining plate are installed as a whole in a square box. Since the process of installing the components on the lining plate is carried out outside the square box, it will not be limited by the space of the square box, which greatly reduces the difficulty of installing the components and improves the installation efficiency of the components.

[0038] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0039] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0040] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0041] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0043] refer to Figure 1 The present application provides a control box, comprising: a square box 1 with one side open, the open side of the square box 1 is covered by a cover plate 2, and the cover plate 2 is removable; a lining plate 3 is installed on the inner side of the square box 1, and the lining plate 3 is installed into the square box 1 from the open side of the square box 1, and the lining plate 3 is removable. The layout position of the lining plate 3 is opposite to the position of the cover plate 2, and the lining plate 3 is used to pre-install components. It can be understood that directly installing components one by one into the square box 1 is very inconvenient and time-consuming and labor-intensive due to space limitations. The components are first installed on the lining plate 3 outside the square box 1, and then the lining plate 3 and the components on the lining plate 3 are installed as a whole into the square box 1. Since the process of installing the components on the lining plate 3 is carried out outside the square box 1, it will not be limited by the space of the square box 1, which greatly reduces the difficulty of installing the components and improves the installation efficiency of the components. It is easy to understand that in one embodiment, the liner 3 is not removable, for example, the liner 3 is directly welded or riveted into the square box 1. Compared with the removable liner 3, this has the disadvantage that it cannot be removed, which makes it inconvenient to disassemble and repair the components on the liner 3.

[0044] It is understandable that the square box 1 can be formed by splicing several plates, or by Figure 5 Preferably, the square box 1 is formed by bending a plate 10, which can improve the integrity of the square box 1 compared to the square box 1 formed by splicing several plates, and can also improve the production efficiency of the square box 1 and reduce the production cost.

[0045] It is worth noting that in order to prevent external dust and foreign objects from entering the control box and reduce the risk of short circuit in the control box, preferably, the control box should be completely closed, that is, the control box has no windows or openings connecting to the outside world, which can improve the sealing of the control box.

[0046] To improve the overall sealing and waterproofness of the control box, refer to Figure 1 In one embodiment, a sealing ring 9 is provided at the connection between the cover plate 2 and the square box body 1 .

[0047] refer to Figure 1 In one embodiment, the fuse 7 is mounted on the liner 3, and a cooling fan 8 is also mounted on the liner 3. The cooling fan 8 faces the fuse 7 and can dissipate heat for the fuse 7. It is easy to understand that the fuse 7 can meet the requirements of the melting speed within the normal operating temperature range, and too high a temperature will increase the risk of failure or delayed melting of the fuse 7. By providing the cooling fan 8, the fuse 7 can be cooled to avoid excessive temperature of the fuse 7, ensuring that the fuse 7 is within the normal operating temperature range, so that the melting speed of the fuse 7 meets the requirements.

[0048] It is easy to understand that the detachable installation mode of the lining plate 3 can be a fixed connection mode, for example Figure 1 The screw connection shown by bolts or screws can also be a movable connection, for example by Figure 6 The card connection method is as follows:

[0049] refer to Figure 1-Figure 3 In one embodiment, a support rib 4 is welded on the inner wall of the square box 1 on the side opposite to the cover plate 2, and the lining plate 3 is fixed to the support rib 4 by bolts or screws. Obviously, by screwing the lining plate 3 to the support rib 4, the fixing strength of the lining plate 3 can be ensured, and the risk of the lining plate 3 shaking relative to the square box 1 can be reduced. It can be understood that the support rib 4 should be able to be welded in the square box 1 and support the lining plate 3 at the same time, that is, the support rib 4 can separate the lining plate 3 from the square box 1 by a certain distance to reserve installation space for the bolts or screws. The cross-sectional forms of the support rib 4 are various, Figure 4 Several different cross-sectional forms are shown in the figure as examples. The cross-sectional form of the support rib 4 can be a groove shape, such as a C shape (like the cross-sectional form of a channel steel), a U shape, a cross-shaped shape, or a Z shape. Preferably, the cross-sectional shape of the support rib 4 is a groove shape, the groove edge of the support rib 4 is welded to the square box body 1, and the groove bottom of the support rib 4 is screwed to the liner 3.

[0050] In one embodiment, in order to improve the installation and removal efficiency of the liner 3, the liner 3 is hung inside the square box 1. There are various ways to hang the liner 3, such as setting a hanging hole in the square box 1 and setting a hook on the liner 3. Figure 6An L-shaped hanging piece 5 is welded on the inner wall of the square box 1 on the side opposite to the cover plate 2, and the lining plate 3 is also provided with a hanging piece 5, and the lining plate 3 is hung on the inner side of the square box 1 through the cooperation of the hanging piece 5. It is easy to understand that by adopting the L-shaped hanging piece 5, on the one hand, the structure of the hanging piece 5 is simple and easy to process and produce, and on the other hand, the L-shaped hanging piece 5 can improve the hanging efficiency of the lining plate 3.

[0051] refer to Figure 1 In one embodiment, a cable fixing seat 6 is installed on the lining plate 3. By setting the cable fixing seat 6, the cable harness 12 is fixed by using the cable tie 11, which can save space in the square box 1 compared to setting a wire trough. In addition, the cable fixing seat 6 is flexibly arranged and does not need to be horizontal or vertical, which is convenient for routing in the square box 1.

[0052] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
