Description

Technical Field

[0001] The present disclosure relates to the technical field of battery devices, and in particular, to an energy storage housing and a battery device having a hidden connection structure. Background Art

[0002] An energy storage battery, also known as a battery device for energy storage, refers to a battery that converts chemical energy or physical energy into electrical energy and has an energy storage function. Its basic principle is to store electrical energy by converting it into chemical energy or physical energy through chemical reactions or physical changes, and then convert the stored chemical energy or physical energy back into electrical energy for release when electrical energy is needed.

[0003] A battery device generally includes an energy storage housing and a cover plate. An upper opening is provided at the upper end of the energy storage housing, and the cover plate is covered on the upper end of the housing body to close the upper opening of the housing body. After the cover plate is covered on the upper end of the housing body, the cover plate is fixed to the housing body by threaded fasteners. For example, CN218632306U - A desk cabinet type household energy storage battery.

[0004] However, since the cover plate is not the main load-bearing structure, in order to save costs, the thickness of the cover plate is usually designed to be relatively thin. Due to the relatively thin thickness of the cover plate, a counterbore for accommodating the end of the fastener cannot be formed on the cover plate, resulting in the edges of the fasteners protruding outside the cover plate. This not only reduces the surface flatness of the energy storage housing but also makes the edges of the fasteners relatively easy to scratch people, thereby reducing the safety of the battery device.

[0033] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with specific embodiments:

[0034] As Figure 1 and Figure 2 shown, a battery device in an embodiment includes an energy storage housing 10 with a hidden connection structure, and the battery device further includes a battery module, and the battery module is fixedly connected inside the cabinet 100.

[0035] As Figures 1 to 3As shown, in some of these embodiments, an energy storage housing 10 with a hidden connection structure includes a cabinet body 100, a cover plate 200, and a plurality of fasteners 300. An upper opening 101 is provided at the upper end of the cabinet body 100, and the cover plate 200 covers the upper opening 101. The back surface of the cabinet body 100 is set against the wall, and a plurality of connection holes 102 are provided on the back surface of the cabinet body 100. The plurality of connection holes 102 are spaced along the circumference of the upper opening 101. A plurality of spaced accommodation holes 201 are provided at the peripheral edge of the cover plate 200.

[0036] As Figures 4 to 6 shown, further, the energy storage housing 10 with a hidden connection structure further includes a plurality of connection pieces 400. The plurality of connection pieces 400 are respectively fixedly connected to the inner wall of the cover plate 200, and each connection piece 400 is provided with an avoidance hole 401. The plurality of fasteners 300, the plurality of accommodation holes 201, the plurality of avoidance holes 401, and the plurality of connection holes 102 are arranged in one-to-one correspondence. Each fastener 300 passes through the corresponding avoidance hole 401.

[0047] 1. Since the connection hole 102 is provided on the back surface of the cabinet body 100, the fastener 300 cooperating with the connection hole 102 is arranged on the back surface of the cabinet body 100. Also, since the back surface of the cabinet body 100 is used for leaning against the wall, the fastener 300 is hidden between the cabinet body 100 and the wall, which improves the flatness of the exposed surface of the energy storage housing.

[0048] 2. Since at least a part of the second end of the fastener 300 is received in the receiving hole 201, the edge 301 of the second end of the fastener 300 is received in the receiving hole 201, avoiding the problem that the edge 301 of the fastener 300 protrudes outside the cover plate 200 and the problem that the edge 301 of the fastener 300 scratches people.
