Description

Technical Field

[0001] This utility model belongs to the field of storage battery technology, specifically relating to a storage battery enclosure. Background Technology

[0002] In practical applications, multiple batteries are often connected in series or parallel to meet voltage, capacity, or power requirements. However, the positive and negative conductive parts of existing batteries protrude from the top of the battery box. Therefore, the top of the battery box is not a flat surface. When multiple batteries need to be connected in series or parallel, they cannot be stacked vertically, resulting in a large amount of space being occupied when multiple batteries are laid flat. Utility Model Content

[0003] This addresses the technical problem of wasted space when existing batteries cannot be stacked for applications.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a battery box, comprising a main box and a top cover. The top of the main box is provided with a connecting part, the width of which is wider than the width of the main box. The top cover is connected to the connecting part of the main box. The upper surface edge of the top cover is provided with a protrusion. The top of the top cover forms a recessed storage groove through the protrusion. The bottom of the main box can be placed in the storage groove on the top of another battery box, so that two or more battery boxes can be stacked vertically for use.

[0005] The present invention has the following advantages: Since batteries often need to be used in pairs or more to facilitate the expansion of battery pack capacity or voltage, the bottom of the battery box of this application can be placed in the storage slot of the cover of another battery box, so that multiple battery boxes can be stacked vertically through the storage structure of the cover, reducing the area occupied by the equipment.

[0010] like Figures 1 to 4As shown, a battery case includes a main case 10 for storing batteries and an upper cover 20. The top of the main case 10 is provided with a connecting part 30, the width of which is wider than the width of the main case 10. The upper cover 20 is connected to the connecting part 30 of the main case 10. The upper surface edge of the upper cover 20 is provided with a protrusion 21, and the top of the upper cover 20 forms a recessed storage groove 22 through the protrusion 21.

[0011] When in use, batteries often need to be used in pairs or more to expand the battery pack capacity or voltage. The bottom of the battery box 10 of this application can be placed in the storage slot 22 of the cover 20 of another battery box 10, so that multiple battery boxes 10 can be stacked vertically through the storage structure of the cover 20, reducing the area occupied by the equipment.

[0012] The main body 10 has protruding handles 31 on both sides of the connecting part 30. The upper cover 20 has openings 23 on both sides corresponding to the handles 31. When the upper cover 20 is closed on the top of the main body 10, the handles 31 on both sides are located in the openings 23 on both sides.

[0013] The upper cover 20 has opening grooves 24 on both sides of the openings 23. When the upper cover 20 needs to be opened or closed with the main box 10, the user can move the upper cover 20 by clamping the upper cover 20 with his / her hands in the opening grooves 24 on both sides.

[0014] The upper cover 20 has a number of screw holes in the protrusion 21, and the main box 10 connecting part 30 has a number of screw holes opposite each other. When the upper cover 20 is located on the top of the main box 10, the two screw holes are connected by screws, so that the connection between the upper cover 20 and the main box 10 is tighter.

[0015] The protrusion 21 on one side of the upper cover 20 is a functional part 40. The two ends of the functional part 40 are respectively provided with a positive conductive element 41 and a negative conductive element 42. When in use, the positive and negative conductive elements of the stacked batteries are electrically connected to the positive and negative conductive elements of another battery through the power line 11, thereby expanding the battery pack capacity or voltage.

[0016] The functional unit 40 includes a control circuit board and a control button 43, which is electrically connected to the control circuit board.

[0017] The control circuit board is equipped with a display screen 44 and a charging port 45. When in use, the display screen 44 can display the battery power, and the charging port 45 can charge electronic products through a charging cable.
