Technical field:
[0001] The utility model relates to the field of photovoltaic cells, and in particular to an assembly structure applied to stacked energy storage batteries. Background technology:
[0002] With the increasing demand for new energy, photovoltaic energy storage has also attracted more and more attention. With the vigorous development of the photovoltaic energy storage industry, a stable and reliable photovoltaic energy storage system is a great supplement to photovoltaic power generation. Due to the large rural layout in European and American countries and the rise of the photovoltaic concept in rural China, household photovoltaic energy storage has gradually entered the homes of ordinary people. Household photovoltaic energy storage has begun to enter thousands of households. Currently, household energy storage batteries are mainly wall-mounted and stacked. Compared with the wall-mounted type, the stacked type has a larger capacity and is easier to install, but because the stacked type is made up of multiple batteries, there are gaps between the batteries, which can easily cause water ingress at the connection port, threatening battery safety.
[0003] Traditional stacked energy storage batteries are usually connected by wires, which are exposed to the air for a long time. If the waterproofing and anti-aging treatments are not done properly, the wires are easily burned. In addition, the wires are exposed on the outer surface, which is not aesthetically pleasing. Utility model content:
[0004] In order to solve the problems in the prior art, the utility model provides an assembly structure for stacked energy storage batteries, which has a simple structure and is easy to install, and can also prevent problems such as short circuits caused by water ingress.
[0005] To achieve the above purpose, the technical solution of the utility model is:
[0006] An assembly structure for stacked energy storage batteries comprises a control layer and a group of battery layers which are stacked and matched with each other; wherein a control system is arranged in the control layer, a groove is arranged at the bottom of the control layer, and a positioning stud and an intermediate interface are arranged in the groove; the top surface of each battery layer is provided with a convex groove matched with the groove, a positioning screw hole and an intermediate interface are arranged in the convex groove, and the bottom surface is provided with a groove matched with the convex groove on the top surface of the next layer, and a positioning stud and an intermediate interface are arranged in the groove; the control layer and a group of battery layers are stacked in sequence to ensure that the convex groove is inserted into the groove so that the surfaces of the two are fitted, and to ensure that the positioning stud is inserted into the positioning screw hole for fixation and the intermediate interface is docked.
[0007] Furthermore, the control layer includes a control box and an upper cover that cooperate with each other. The bottom of the control box is integrally formed with a groove. The upper cover is buckled on the control box to ensure that the upper surface is flush. A waterproof rubber strip is provided at the periphery of the upper cover and the control box. The inner edge of the bottom of the control box is provided with a ring groove to cooperate with each battery layer.
[0008] Furthermore, each battery layer includes a shell and a cover body that cooperate with each other. The cover body is integrally formed with a convex groove upward, and the bottom of the shell is integrally formed with a groove. The cover body is buckled on the top of the shell and ensures that part of it protrudes out of the shell. The protruding part is just snapped into the ring groove at the bottom of the control box for positioning, and a waterproof rubber strip is provided at the periphery of the cover body and the matching place with the shell.
[0009] Furthermore, the intermediate interface includes parallel holes between batteries and communication holes between layers.
[0010] Furthermore, slots are provided at the bottom of both sides of the control layer and each battery layer to facilitate installation and removal.
[0011] Furthermore, the grooves and the convex grooves are respectively arranged at the edges of the control layer and each battery layer, and are marked with installation direction indications.
[0012] By adopting the above structure, the utility model solves the problem that the stacked energy storage interface is easily affected by moisture and water, which poses a safety hazard. A groove is opened at the bottom of the upper part, and a positioning stud is arranged in the groove. The middle interface includes parallel holes between batteries and communication positions between layers. The batteries of the upper and lower layers can be connected in parallel and communicate with each other without exposing bare wires. A convex groove is opened on the top of the lower part, and a positioning screw hole is arranged inside to connect with the positioning stud to prevent problems such as movement of the upper layer.
[0013] The utility model cleverly designs a protrusion and a groove between the stacked energy storage batteries for assembly, and has positioning studs inside for positioning. The power transmission port automatically completes the matching, and no external wires are required. The structure is simple and the installation is convenient. At the same time, it can also prevent problems such as short circuits caused by water ingress. Description of the drawings:
