Description

Technical Field

[0001] This invention relates to the field of battery energy storage box technology, and in particular to a plug panel structure for an energy storage battery box. Background Technology

[0002] A battery storage box is a casing structure used to store batteries. A typical casing structure has a double-layered bottom plate forming a cooling water plate layer, which uses circulating cooling water to cool the batteries during charging and discharging. The end face of the battery storage box usually has a connector panel with channels that communicate with the cooling water plate layer. One end of the channel is the external interface for cooling water circulation, and the other end is welded to the cooling water plate layer. However, the flow channel structure on the connector panel of a conventional battery storage box is formed by drilling holes in the relatively thick connector panel to create channels for accommodating cooling water. This method of creating channels has the following disadvantages: Figure 1 Figure 2 As shown: First, in order to ensure the flow rate of cooling water in the flow channel, the flow channel needs to be set to meet the required aperture. However, in order to meet the aperture requirement, the wall thickness of the plug panel needs to be increased to ensure the aperture requirement for drilling. This results in high material consumption and high cost during the molding of the plug panel in order to meet the wall thickness requirement, causing a waste of resources. Second, the processing time for drilling holes in this type of plug panel structure with thicker walls is long, and the waste generated by drilling is serious, resulting in low production efficiency and high energy consumption. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a connector panel structure for an energy storage battery box, which can solve the problems of large thickness of the connector panel of conventional energy storage battery boxes, and low production efficiency and serious waste of raw materials caused by drilling and opening flow channels and welding it to the base plate.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: a plug-in panel structure for an energy storage battery box, wherein the plug-in panel structure is installed on the end face of the energy storage battery box; the bottom plate of the energy storage battery box has a double-layer structure, a circulating cooling water channel is provided inside the bottom plate, and a cooling water inlet and outlet circulation port is provided on one end face of the bottom plate; its innovation lies in: including an outer frame plate and a channel sealing plate;

[0005] The outer frame plate includes a vertical side and a horizontal side, and the vertical side and the horizontal side are integrally formed to form an L-shaped structure; the top edge of the vertical side of the outer frame plate is bent and provided with several connecting holes for installing the cover structure of the energy storage battery box; the vertical side of the outer frame plate is provided with an opening for installing a plug-in panel and a cooling water inlet and outlet pipe, and the cooling water inlet and outlet pipe is located above the upper surface of the horizontal side in the horizontal direction; a water groove is opened on the upper surface of the horizontal side corresponding to the position of the cooling water inlet and outlet pipe, and one end of the water groove extends to the lower part of the cooling water inlet and outlet pipe on the vertical side, and the other end of the water groove extends to the edge of the horizontal side;

[0006] The flow channel sealing plate has a pair of plates that are respectively welded to the water tank on the upper surface of the horizontal side. The cross-section of the flow channel sealing plate is U-shaped, and the inner wall of the flow channel sealing plate and the water tank form a cavity to accommodate cooling water. One end of the flow channel sealing plate is welded to the inner wall of the vertical side so that one end of the cavity to accommodate cooling water is connected to the cooling water inlet and outlet pipe. The other end of the flow channel sealing plate is welded to the cooling water inlet and outlet circulation port on the base plate so that the other end of the cavity to accommodate cooling water is connected to the end of the base plate.

[0007] Furthermore, the outer frame plate has openings on its vertical side for mounting the connector panel.

[0008] Furthermore, the thickness of the horizontal side of the outer frame plate is less than the thickness of the bottom plate of the energy storage battery box.

[0009] The advantages of this invention are:

[0010] 1) In this invention, the horizontal panel of the outer frame adopts a thin plate structure. By opening water grooves on the horizontal panel, a flow channel structure is formed with the flow channel sealing plate, which then connects to the circulation port on the bottom plate of the energy storage battery box. With this structure, on the one hand, the horizontal panel of the outer frame is thin, which saves raw materials. On the other hand, the flow channel on the thin outer frame can only be formed by opening water grooves and flow channel sealing plates, which reduces the processing time of drilling holes in the horizontal panel of the outer frame and greatly improves the processing efficiency.

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0018] like Figures 3 to 4 The diagram shows a plug-in panel structure for an energy storage battery box. The plug-in panel structure is installed on the end face of the energy storage battery box. The bottom plate of the energy storage battery box has a double-layer structure. A circulating cooling water channel is provided inside the bottom plate, and a cooling water inlet and outlet circulation port is provided on one end face of the bottom plate. It includes an outer frame plate 1 and a channel sealing plate 2.

[0019] The outer frame plate 1 includes a vertical side 11 and a horizontal side 12, and the vertical side 11 and the horizontal side 12 are integrally formed to form an L-shaped structure. The top edge of the vertical side 11 of the outer frame plate 1 is bent and provided with several connecting holes for installing the cover structure of the energy storage battery box. The vertical side 11 of the outer frame plate 1 is provided with an opening for installing a plug-in panel and a cooling water inlet / outlet pipe 13, and the cooling water inlet / outlet pipe 13 is located above the upper surface of the horizontal side in the horizontal direction. A water groove is opened on the upper surface of the horizontal side 12 corresponding to the position of the cooling water inlet / outlet pipe 13, and one end of the water groove extends to the bottom of the cooling water inlet / outlet pipe 13 of the vertical side 11, and the other end of the water groove extends to the edge of the horizontal side.

[0020] The flow channel sealing plate 2 has a pair of water tanks that are respectively welded to the upper surface of the horizontal side 12. The cross-section of the flow channel sealing plate 2 is U-shaped, and the inner wall of the flow channel sealing plate 2 and the water tank form a cavity to accommodate the passage of cooling water. One end of the flow channel sealing plate 2 is welded to the inner wall of the vertical side 11 so that one end of the cavity to accommodate the passage of cooling water is connected to the cooling water inlet / outlet pipe 13. The other end of the flow channel sealing plate 2 is welded to the cooling water inlet / outlet circulation port on the bottom plate so that the other end of the cavity to accommodate the passage of cooling water is connected to the end of the bottom plate.

[0022] The thickness of the horizontal side of the outer frame plate 1 is less than the thickness of the bottom plate of the energy storage battery box.

[0023] The working principle of this invention is as follows: the horizontal panel of the outer frame adopts a thin plate structure. By opening water grooves on the horizontal panel, a flow channel structure is formed with the flow channel sealing plate, which then connects to the circulation port on the bottom plate of the energy storage battery box. With this structure, on the one hand, the horizontal panel of the outer frame is thin, saving raw materials. On the other hand, the flow channel on the thin outer frame can only be formed by opening water grooves and flow channel sealing plates, which reduces the processing time of drilling holes in the horizontal panel of the outer frame and greatly improves processing efficiency.
