Description

Technical Field

[0001] This utility model belongs to the field of battery protection technology, specifically relating to an explosion-proof energy storage gel battery. Background Technology

[0002] A storage battery is a device that directly converts chemical energy into electrical energy. It is a battery designed to be rechargeable, and it is recharged through a reversible chemical reaction. It usually refers to lead-acid batteries, which are a type of battery and belong to secondary batteries. Its working principle is as follows: when charging, external electrical energy is used to regenerate the internal active materials and store the electrical energy as chemical energy. When discharging is needed, the chemical energy is converted back into electrical energy for output.

[0003] When the internal temperature of a battery continues to rise during use, it can cause the battery to expand due to heat, increasing the likelihood of an explosion and endangering the user's life. Utility Model Content

[0004] The purpose of this invention is to provide an explosion-proof energy storage gel battery to solve the problem that existing batteries are prone to explosion due to high internal temperatures.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An explosion-proof energy storage gel battery includes a casing, inside which a battery cell is installed, and a cover plate is installed on the end face of the casing. An auxiliary mechanism is provided inside the casing, the auxiliary mechanism including an airbag cushion disposed on the bottom wall inside the casing, a filter screen fixedly connected to the inner wall of the casing, the battery cell being located above the filter screen, and the airbag cushion being located below the filter screen.

[0007] Preferably, the housing has a rectangular box inside, the bottom of the rectangular box has multiple rectangular holes, a rectangular block is engaged inside the rectangular holes, and a rectangular plate is fixedly connected to the bottom surface of the rectangular block.

[0008] Preferably, both the rectangular block and the rectangular plate are made of plastic, and the interior of the rectangular box contains dry powder.

[0009] Preferably, the end face of the cover plate is fixedly connected to two upright blocks, the surfaces of the two upright blocks are rotatably connected to a rotating rod, and the arc surface of the rotating rod is fixedly connected to a protective plate.

[0010] Preferably, a fixing plate is fixedly connected to the end face of the cover plate, and a plug rod is slidably inserted into the surface of the fixing plate. The arc surface of the rotating rod has multiple insertion holes.

[0011] Preferably, a plurality of the sockets are circumferentially formed on the arc surface of the rotating rod, and the size of the sockets is adapted to the size of the rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by setting up an airbag cushion, a filter screen, a rectangular box, rectangular holes, and rectangular blocks, uses a filter screen to support the battery cell. When the battery cell catches fire, it allows carbon dioxide gas in the airbag cushion to leak out, reducing the oxygen content inside the casing. Furthermore, under the action of the rectangular box, it allows the dry powder inside the rectangular box to leak out, improving the fire extinguishing effect and extinguishing the fire generated by the battery cell.

[0014] 2. This utility model, by setting a protective plate, a plug rod, and a socket, can shield and protect the electrodes on the cover plate by rotating the protective plate. The mutual locking of the plug rod and the socket improves the stability of the protective plate, thereby achieving the effect of protecting the electrodes and minimizing dust accumulation when not in use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-4 As shown, this utility model provides an explosion-proof energy storage gel battery, including a housing 1, a battery cell 101 installed inside the housing 1, a cover plate 102 installed on the end face of the housing 1, an auxiliary mechanism 2 provided inside the housing 1, the auxiliary mechanism 2 including an airbag 201 disposed on the bottom wall inside the housing 1, a filter screen 202 fixedly connected to the inner wall of the housing 1, the battery cell 101 being located above the filter screen 202, and the airbag 201 being located below the filter screen 202.

[0022] In this embodiment, the airbag cushion 201 is filled with carbon dioxide gas for fire extinguishing.

[0023] In an optional embodiment: a rectangular box 203 is provided inside the housing 1, and a plurality of rectangular holes 204 are provided at the bottom of the rectangular box 203. A rectangular block 205 is engaged inside the rectangular hole 204, and a rectangular plate 206 is fixedly connected to the bottom surface of the rectangular block 205.

[0024] In an optional embodiment: both rectangular block 205 and rectangular plate 206 are made of plastic, and the interior of rectangular box 203 contains dry powder.

[0025] It should be noted that rectangular block 205 and rectangular plate 206 can be burned, so that the dry powder inside rectangular box 203 will leak out and be used for fire extinguishing.

[0026] In an optional embodiment: two upright blocks 207 are fixedly connected to the end face of the cover plate 102, and rotating rods 208 are rotatably connected to the surfaces of the two upright blocks 207. A protective plate 209 is fixedly connected to the arc surface of the rotating rods 208.

[0027] In an optional embodiment: a fixing plate 210 is fixedly connected to the end face of the cover plate 102, and a plug rod 211 is slidably inserted into the surface of the fixing plate 210. A plurality of plug holes 212 are opened on the arc surface of the rotating rod 208.

[0028] In an optional embodiment: a plurality of sockets 212 are circumferentially formed on the arc surface of the rotating rod 208, and the size of the sockets 212 is adapted to the size of the rod 211.

[0029] It should be noted that when not in use, rotating the rotating rod 208 will cause the protective plate 209 to rotate, so that the protective plate 209 covers the electrode. By inserting the insertion rod 211 into the corresponding insertion hole 212, the protective plate 209 is secured, thus achieving the function of protecting the electrode.

[0030] The working principle of this utility model is as follows: When in use, if the battery cell 101 inside the housing 1 catches fire, the resulting flame will rupture the airbag cushion 201, releasing the carbon dioxide inside the airbag cushion 201, thereby reducing the oxygen content inside the housing 1. At the same time, the flame will burn the rectangular plate 206 and the rectangular block 205, and the dry powder inside the rectangular box 203 will leak out from the rectangular hole 204, covering the battery cell 101. Thus, under the dual action of carbon dioxide and dry powder, the fire can be extinguished, thereby reducing the risk of explosion. During normal use, if not in use, the rotating rod 208 is rotated to drive the protective plate 209 to rotate, so that the protective plate 209 covers the electrode. By inserting the plug rod 211 into the corresponding plug hole 212, the protective plate 209 is secured, thereby achieving the function of protecting the electrode.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
