The present invention will be described in further detail with reference to specific embodiments in order to make the above objects, features and advantages more apparent and understandable.
First, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.
Next, the present invention is described in detail by using a schematic structural diagram, etc., and for convenience of description, the schematic diagram illustrating the structure of the fire-proof battery pack is not partially enlarged according to a general scale when describing the embodiment of the present invention, and the schematic diagram is only an example, which should not limit the scope of the present invention. In addition, the actual fabrication process should include three-dimensional space of length, width and depth.
Example one
Referring to fig. 1, fig. 1 is a schematic perspective view illustrating an embodiment of a fire-proof battery pack according to the present invention. As shown in fig. 1, the fireproof battery pack includes: a battery device (not shown), an insulation packet device 1, a pipe 2 and an oxygen removal device 3.
Isolated package device 1 cladding is outside the battery device, be equipped with an opening on the isolated package device 1, the opening with the one end of pipeline 2 is sealed and is connected, the other end of pipeline 2 with deaerating plant 3 is connected. The insulation package device 1 is provided with an electric wire outlet 4 and an electric wire inlet 5, and the insulation package device 1 at the electric wire outlet 4 and the electric wire inlet 5 is in seamless butt joint with the battery device. The battery device is isolated from the outside air by the insulation bag device 1, and the air between the insulation bag device 1 and the battery device is discharged through the oxygen removing device 3, so that the possibility of fire is prevented from being increased due to the combustion assistance of oxygen in the outside air when the temperature of the battery device is too high.
In order to improve the oxygen removing effect and enhance the safety, the oxygen removing device 3 may be a closed structure, an oxygen removing agent is filled in the oxygen removing device 3, and in order to add the oxygen removing agent in the oxygen removing device 3, the oxygen removing device 3 is connected with the pipeline through a thread.
