DETAILED DESCRIPTION

[0039] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0040] In the present disclosure, unless otherwise specified, the directional words used, such as "upper, lower, top, bottom", generally refer to the control box provided in the present disclosure under normal use. "Inside and outside" may refer to the inside and outside of the corresponding component outline or its location inside or outside the environment, depending on the specific context. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The terms "first", "second", etc. used in the present disclosure are to distinguish one element from another and do not have sequentiality or importance.

[0041] like Figures 1 to 5 As shown, the first object of the present disclosure is to provide a control box 9, which includes a box-shaped base 1 with an opening 11 and a cover plate 2 covering the opening 11, wherein the box-shaped base 1 includes a bottom plate 12 and a plurality of side plates 13 erected on the edge of the bottom plate 12, and the bottom plate 12 and the plurality of side plates 13 are an integral part. The box-shaped base 1 can be formed in the form of an integral sheet metal being bent and then welded, that is, the box-shaped base 1 can first be formed by bending an integrally formed sheet metal into a box shape, and then the remaining connection positions are welded to form the box-shaped base 1. The cover plate 2 can be detachably covered at the opening for easy maintenance.

[0042] Through the above technical solution, the bottom plate 12 and the multiple side plates 13 are an integrated part. During the preparation process of the box-shaped base 1, compared with the technical solution of welding multiple plates to form the box-shaped base 1, the amount of welding is reduced, the production and processing time of the control box 9 is reduced, and the welding positions of the control box 9 are reduced, so as to avoid too many welding positions and improve the sealing and overall structural strength of the control box 9. In addition, the space inside the box-shaped base 1 can accommodate various electronic devices of the control box 9, and the electronic devices can be installed from top to bottom in the box-shaped base 1 from the opening 11, and the cover plate 2 is covered on the opening 11 to seal the box-shaped base 1, which is easy to assemble.

[0043] The bottom plate 12 and the side plates 13 erected on the edge of the bottom plate 12 can form a box-shaped internal space, and various electronic devices can be arranged on the bottom plate 12 and the side plates 13 directly or through brackets. At the same time, the side plates 13 are erected on the edge of the bottom plate 12, and the side plates 13 can also protect the electronic devices in the control box 9. The box-shaped base 1 can be a rectangular parallelepiped, a cube, a prism, etc., which is not limited in the present disclosure.

[0044] In some embodiments, the box-shaped base 1 can be formed by bending a bottom plate 12 and a plurality of side plates 13 constructed as an integral piece into a box shape through an integral sheet metal, and then welding the remaining connection positions to form the box-shaped base 1.

[0045] In some embodiments, when the box-shaped base 1 is formed by bending a single piece of sheet metal and then welding, the bottom plate 12 and the plurality of side plates 13 may be bent as a single piece of sheet metal, and the connecting edges of two adjacent side plates 13 may be welded and fixed to form the box-shaped base 1. Figure 1 For example, the box-type base 1 is composed of a rectangular bottom plate 12 and four side panels 13 erected on the edges of the rectangular bottom plate 12. When the one-piece sheet metal is a square structure, it can be cut. At this time, the one-piece sheet metal can be one of the four edges of the bottom plate 12, each of which has a side panel 13 integrally formed on it. The four side panels 13 are bent from the sheet metal and erected on the four edges of the bottom plate 12. In this way, the box-type base 1 can be formed by welding and fixing the connecting edges of two adjacent side panels 13.

[0046] In some other embodiments, when the box-shaped base 1 is formed by bending a single piece of sheet metal and then welding, the bottom plate 12 and the plurality of side plates 13 may be bent as a single piece of sheet metal, and the connecting edges of the two opposite side plates 13 and the connecting edges of a portion of the side plates 13 and the bottom plate 12 may be welded and fixed to form the box-shaped base 1. Figure 1For example, the box-type base 1 is composed of a bottom plate 12 and a strip plate integrally formed on one edge of the bottom plate 12. The strip plate can be formed into multiple side plates 13 after multiple bending. After the strip plate is bent, the connecting edges of the two side plates 13 at both ends are welded and fixed, and then the connecting edges of the side plates 13 and the bottom plate 12 are welded and fixed to form the box-type base 1. The above are all expanded embodiments of the forming method of bending and welding the integrated sheet metal, and the forming methods that can form the box-type base 1 all belong to the protection scope of the present disclosure.

[0047] Reference Figure 2 The box-shaped base 1 has a flange 131 bent inward from the top of the side panel 13. The flange 131 is used to enclose the opening 11 of the box-shaped base 1. The cover plate 2 is placed on the flange 131 to close the opening 11. The flange 131 and the side panel 13 are formed by bending an integral sheet metal. When the box-shaped base 1 is formed, the flange 131 can be formed at the same time, further speeding up the production and processing time of the box-shaped base 1. Compared with being directly connected to the upper edge of the side panel 13, the cover plate 2 is fixed to the flange 131, so that there can be more contact area between the cover plate 2 and the flange 131, ensuring the sealing effect when the cover plate 2 is opened at the opening 11.

[0048] The inner edge of the flange 131 may be provided with an upwardly protruding annular abutment 132, and the cover plate 2 is placed on the annular abutment 132 to close the opening 11. Figure 1 and Figure 2 The annular abutment platform 132 can support the cover plate 2, and the annular abutment platform 132 protrudes upward. At this time, the cover plate 2 can be located above the flange 131. The cover plate 2 will not affect the electrical components and connecting harnesses in the control box 9, and it is more convenient for the operator to remove the cover plate 2.

[0049] The cover plate 2 may include a main board 21 and at least two support members 22 vertically connected to opposite side walls of the main board 21. The main board 21 is fitted and connected to the side of the annular abutment platform 132 away from the bottom plate 12. The support member 22 is located on the outer side of the annular abutment platform 132 and abuts against the flange 131. The top surface of the annular abutment platform 132 and the flange 131 can support the cover plate 2 respectively, making the cover plate 2 more stable. At the same time, the outer wall surface of the annular abutment platform 132 can cooperate with the inner wall surface of the support member 22 to limit the cover plate 2 and prevent the cover plate 2 from shifting when the cover is set at the opening 11.

[0050] A sealing strip may be provided between the cover plate 2 and the box-shaped base 1. The sealing strip is adapted to the outer contour of the annular abutment platform 132, and the sealing strip is located between the annular abutment platform 132 and the support member 22. The sealing strip is adapted to the outer contour of the annular abutment platform 132, thereby ensuring the contact area between the sealing strip, the annular abutment platform 132 and the support member 22, and ensuring the sealing effect of the sealing strip. The sealing strip may be made of an elastic material, so that when the cover plate 2 is used, the sealing strip made of the elastic material can fill the gap between the annular abutment platform 132 and the support member 22, further ensuring the sealing effect of the cover plate 2, and ensuring the sealing of the control box as a whole.

[0051] The box-shaped base 1 may have a cavity, and the control box 9 may also include a PCB board 3 disposed in the cavity and electronic devices mounted on the PCB board 3. The electronic devices may include at least one of a relay, a circuit breaker, and a control board. In this way, the small electronic components at the board end and the circuits inside the PCB board 3 may be used to replace many conventional external devices with larger sizes, space-consuming devices, and plug-ins, so that the interior of the control box 9 is more compact and highly integrated. When the control box 9 needs to be connected to other control components, all the electronic control, power distribution, insurance, and other devices except the battery box 8 can be centrally arranged inside the control box 9, reducing the mounting brackets required when the control box 9 needs to be connected to other control components, saving space, and at the same time shortening the length of the connection harness, further reducing costs.

[0052] A guard plate 4 may also be provided on the outside of the box-shaped base 1 and / or the cover plate 2. The guard plate 4 may protect the outside of the box-shaped base 1 and the outside of the cover plate 2 to prevent the deformation of the box-shaped base 1 and the cover plate 2 from affecting the use of the electronic devices inside the control box 9. The guard plate 4 may be selected according to the requirements of the layout environment of the control box 9. For example, in an environment with a lot of charges, in order to prevent the control box 9 from generating static electricity and to prevent the control box 9 from conducting electricity, an insulating plate may be selected for the guard plate 4. In an environment with strong corrosiveness, a corrosion-resistant material may be selected for the guard plate 4, which can increase the corrosion resistance of the control box 9 and improve the use strength and service life of the control box 9.

[0053] The guard plate 4 may include a first plate 41 and / or a second plate 42. The first plate 41 is arranged on the outside of the first side plate 133 of the box-shaped base 1. The second plate 42 includes a horizontal plate 421 and a vertical plate 422. The horizontal plate 421 is arranged on the top of the cover plate 2, and the vertical plate 422 is arranged on the outside of the second side plate 134 of the box-shaped base 1. Figure 1 For reference, taking the guard plate 4 including the first plate 41 and the second plate 42 as an example, the first side plate 133 of the box-type base 1 can be the box-type base 1 at Figure 1 The side panels 13 on the left and right sides of the middle and the second side panels 134 can be Figure 1The side panel 13 at the middle front side, the electronic components in the control box 9 usually need to be connected with some other external electronic components by connecting wire harnesses, and the connecting wire harnesses usually pass through the two first side panels 133. When the first panel 41 is set on the first side panel 133, the first panel 41 can also be provided with a hole for avoiding the connecting wire harness, so as to further protect the first side panel 133 and the connecting wire harness passing through the first side panel 133. Figure 1 The second plate 42 can be constructed as an L-shaped structure with a horizontal plate 421 and a vertical plate 422, so that the horizontal plate 421 can protect the cover plate 2, and the vertical plate 422 can be added with relevant indication marks to facilitate operators to better judge the working conditions of the control line. The horizontal plate 421 and the vertical plate 422 are integrated, and the first plate 41 and the second plate 42 can be separate components, which are respectively welded and fixed at corresponding positions of the box-shaped base 1. The first plate 41 is welded and fixed to the non-recessed part of the first side plate 133, such as Figure 1 As shown, the first side plate 41 is also provided with an operation port connected to the outside for leading out the wiring harness. The longitudinal plate 422 is welded and fixed to the second side plate 134, and the transverse plate 421 is fixed to the overlapping edge 411 of the first plate 41 below, which can ensure the overall sealing and structural integrity.

[0054] The top of the first plate 41 may have a bent overlapped edge 411, and the edge of the transverse plate 421 may be formed with a flange 423 connected to the overlapped edge 411. In this way, the first plate 41 and the second plate 42 may be connected to each other through the overlapped edge 411 and the flange 423 being connected and fixed. When the cover plate 2 is covered at the opening 11, the first plate 41 and the transverse plate 421 may further make the cover plate 2 more stable.

[0055] The electronic components in the control box 9 will emit heat when in use. When the control box 9 is connected to components such as the battery box 8, the heat emitted by the battery box 8 will also affect the control box 9. When the temperature in the control box 9 is high, it will affect the use of the electronic components in the control box 9. In order to prevent the excessive temperature in the control box 9 from affecting the use of the electronic components, a first air duct may be provided between the first side panel 133 and the first plate 41, and / or a second air duct may be provided between the second side panel 134 and the longitudinal plate 422. When the gas flows in the first air duct and the second air duct, it can take away the heat from the surface of the control box 9, so that the temperature in the control box 9 will not be too high. When the control box 9 is connected to components such as the battery box 8, the first air duct and the second air duct may be provided close to the connection position between the control box 9 and the battery box 8. At this time, you can refer to Figure 4At this time, the first air duct and the second air duct can also help the battery box 8 to dissipate heat. In order to promote the circulation of gas in the first air duct and the second air duct, if the space in the first air duct and the second air duct allows, fans can be respectively provided in the first air duct and the second air duct to promote the circulation of gas in the first air duct and the second air duct to ensure the heat dissipation effect of the first air duct and the second air duct.

[0056] Reference Figure 3 The first side plate 133 may have a recessed portion 135 recessed into the cavity of the box-shaped base 1, and the first plate 41 is attached to the first side plate 133, and a portion of the first plate 41 forms a first air duct with the recessed portion 135. When the first side plate 133 is bent as an integral sheet metal, the recessed portion 135 can be formed without additional processing steps. At the same time, the size of the recessed portion 135 can be adaptively designed according to the arrangement of the electronic components in the control box 9.

[0057] The second side plate 134 can be spaced apart from the longitudinal plate 422 to form a second air duct. The size of the second air duct can be adaptively designed according to the spacing between the second side plate 134 and the longitudinal plate 422. When the spacing between the second side plate 134 and the longitudinal plate 422 is larger, more gas can flow and the heat dissipation effect will be better.

[0058] A first mounting bracket 61 that matches the external structure may be provided on the outer side of one of the side panels 13 of the box-shaped base 1. The first mounting bracket 61 may be fixed to the back of the box-shaped base 1 by fasteners, and as a wall-mounted component, an operator may place the control box 9 at a desired location by means of the first mounting bracket 61. The present application does not impose any specific restrictions on the structure of the first mounting bracket 61, and it only needs to match the second mounting bracket 62 on the base described below.

[0059] The control box 9 can be stacked on the top of the battery box 8. The top surface of the battery box 8 is provided with a positioning pin, and the bottom plate 12 of the box-shaped base 1 is provided with a positioning hole 7 that matches the positioning pin. The positioning pin can match the positioning hole 7, so that the control box 9 and the battery box 8 can be better positioned when stacked, avoiding displacement of the control box 9 and the battery box 8 when stacked.
