It can be set up with a space for storing batteries inside it, and the stress performance of the composite panel can be reduced or not reduced. Therefore, it is necessary to propose a technical solution to set the battery for storing electric energy inside the composite panel.

[0041] The utility model discloses a laminated plate structure with an embedded battery connection box, referring to Figure 1 , including a prefabricated bottom plate 1 and a hollow battery connection box 3, the upper surface of the prefabricated bottom plate 1 has exposed truss steel bars, the top of the truss steel bars is laid with an upper steel mesh 2, and the battery connection box 3 is arranged between the truss steel bars and the upper steel mesh 2, refer to Figure 2 , 3 There are two battery connection boxes 3. In this embodiment, the battery connection boxes 3 are arranged in an L shape. The battery connection box 3 includes a mounting section and a connecting section. One end of the connecting section penetrates the lower surface of the prefabricated base plate 1 and is connected to the prefabricated base plate 1 by a connecting piece, and the other end is connected to the mounting section. This arrangement can ensure the connection between the battery connection box 3 and the prefabricated base plate 1, and at the same time facilitate the installation of the sheet-type storage battery 7 in the battery connection box 3.

[0042] Reference Figure 4 , 7 At least one sheet-shaped storage battery 7 is slidably arranged in the battery connection box 3, all the sheet-shaped storage batteries 7 are connected by wires, and at least one sheet-shaped storage battery 7 is connected to an external power generation device by a wire, such as the outermost sheet-shaped storage battery 7 is connected to a wire, extending out of the battery connection box 3 and connected to the power generation device.

[0043] The battery connection box 3 is provided with a sliding track 4 along its longitudinal axis, and the sheet-shaped storage battery 7 slides along the longitudinal direction of the sliding track 4. The sliding track 4 includes a connecting plate 41 and a track plate 42. The connecting plate 41 is vertically arranged on the inner top of the battery connection box 3; the track plate 42 is connected to the side of the connecting plate 41 away from the battery connection box 3, and the track plate 42 is slidably connected to the sheet-shaped storage battery 7.

[0044] Reference Figure 6 In order to facilitate the sliding of the sheet-like storage battery 7 , a roller 10 is provided between the track plate 42 and the sheet-like storage battery 7 , and the roller 10 slides along the track plate 42 .

[0045] A battery connection plate 6 is provided between the sheet battery 7 and the roller 10. The sheet battery 7 is detachably connected to the bottom of the battery connection plate 6, such as by screw structure or adhesive, etc. The detachable sheet battery 7 is for the convenience of replacement and daily maintenance. In this embodiment, a mounting connector is provided on the side of the battery connection plate 6 close to the track plate 42. The mounting connector includes a first section, a second section and a third section connected in sequence. The end of the first section away from the second section is fixedly connected to the top of the battery connection plate 6 (such as welding or screw connection), and the end of the third section away from the second section is connected to the roller 10 through a pin structure.

[0046] The track plate 42 is provided with limiting protrusions 5 on both sides along its length axis. In this embodiment, the limiting protrusions 5 are in the form of long arc structures with a major arc cross section. The height thereof is higher than the surface of the track plate 42 , thereby limiting the position of the roller 10 to prevent the roller 10 from derailing.

[0047] One end of the track plate 42 is provided with a fixed slot 11 that matches with the roller 10. The fixed slot 11 can lock the position of the roller 10. When installing multiple sheet batteries 7, the fixed slot 11 can be fixed with the corresponding roller 10 to achieve the fixation of the sheet battery 7. During installation, the roller 10 is loaded from one end of the track plate 42, and the roller 10 is pushed through the fixed slot 11 at this end until the roller 10 matches with the fixed slot 11 at the other end of the track plate 42. At this time, the fixed slot 11 at the loading end matches with the roller of the last sheet battery 7. In order to lock the position of the roller 10 in the fixed slot 11, a rotating limit plate is provided on the track plate 42. One end of the limit plate is rotatably connected with the track plate 42 through a pin with damping, and the other end can be rotated and suspended on the first slot. When the roller 10 is located in the fixed slot 11, the position of the roller can be locked by rotating the limit plate to contact with the roller 10. During installation, the rollers 10 are pushed in from one end of the track plate 42 in sequence until the last group of rollers 10 are located in the fixed slot 11, and then the limit plate is manually rotated to make it contact with the rollers 10 to complete the manual locking of the rollers 10. At the other end of the track plate 42, the rollers 10 slide into the installation section of the battery connection box 3 under the action of gravity. In order to increase the safety and stability of the installation, the surface of the other end of the track plate 42 in contact with the rollers 10 is roughened to increase the friction between the track plate 42 and the rollers 10. The track plate 42 is tilted in the connection section, that is, as it moves away from the installation section, the surface elevation of the track plate 42 gradually decreases, so that the sheet-shaped storage battery 7 can drive the rollers 10 to slide down under the action of its gravity.

[0048] Reference Figure 5 , 6The length axis of the sheet battery 7 is perpendicular to the length axis of the track plate 42. The battery connecting plates 6 of two adjacent sheet batteries 7 are provided with connecting springs 8 for connection. Both ends of the connecting springs 8 are detachably connected to the battery connecting plates 6. The connecting springs 8 are used to achieve the connection of multiple sheet batteries 7. The connection and arrangement of multiple sheet batteries 7 can be completed by only pushing one sheet battery 7 to move. At the same time, the flexible connection method can facilitate the change of position, which helps to improve the arrangement flexibility of the sheet batteries 7. In this embodiment, hooks are provided at both ends of the connecting spring 8, and mounting rings are provided on both sides of the battery connecting plate 6. The hooks cooperate with the mounting rings.
