Description

Technical Field

[0001] The utility model relates to the technical field of fire safety, and in particular to a fire blanket storage device for an electric vehicle charging station. Background Art

[0002] Lithium-ion batteries are widely used in the field of electric vehicles due to their high energy density, long cycle life, wide operating temperature range, and no memory effect. However, lithium-ion batteries are prone to thermal runaway due to their own characteristics and usage environment. Thermal runaway can cause thermal damage to lithium-ion batteries, leading to spontaneous combustion or even explosion of the vehicle. At present, the factors that induce thermal runaway of lithium-ion batteries can be divided into three categories: mechanical abuse (puncture, extrusion deformation, external collision), electrical abuse (overcharge, overdischarge, short circuit), and thermal abuse (failure of the thermal management system). In electrical abuse, if the charging current is too large or the voltage is too high for a long time, it will cause excessive pressure inside the battery. When the pressure reaches a certain level, it will cause the internal temperature of the battery to rise, eventually causing thermal runaway. For this reason, fire-fighting equipment must be mandatory in electric vehicle charging stations. In particular, electric vehicles are often parked together when charging. When an electric vehicle catches fire, it is likely to cause a chain fire, causing serious economic losses. Therefore, existing electric vehicle charging stations are often equipped with fire blankets. By covering the electric vehicle on fire with the fire blanket, the fire can be extinguished while isolating it from other vehicles, effectively preventing the adverse effects caused by the spread of the fire.

[0003] In order to facilitate timely use in the event of a fire, fire blankets are usually stored in obvious locations, such as around charging piles. If they are placed outdoors for a long time, the box used to store the fire blanket is easily eroded by wind and rain, especially the bottom of the box is prone to rust and damage. For this reason, technicians in this field think of setting the box for storing the fire blanket off the ground. However, the fire blanket used to cover electric vehicles weighs tens of kilograms, which puts considerable pressure on the bottom of the suspended box. Although the material of the box or the thickness of its bottom can be optimized to meet the load-bearing requirements, this will lead to an increase in cost. Furthermore, how to improve the load-bearing capacity of the suspended box without significantly increasing the cost is a technical problem that technicians in this field urgently need to solve.

Compared with the flat-bottomed bottom structure, the load-bearing capacity of the box body 10 can be significantly improved.

[0028] It is understandable that the fire blanket storage device provided by the utility model does not improve the material or bottom thickness of the box 10, but only adjusts the bottom structure. Furthermore, the fire blanket storage device provided by the utility model can improve the load-bearing capacity of the suspended box 10 without significantly increasing the cost, so that it can meet the storage requirements of the fire blanket, and at the same time prevent the bottom of the box 10 from contacting the ground for a long time and causing rust damage.

[0029] It should be noted that, in the present invention, the protrusion 111 can be extended in any appropriate direction as long as the top of the protrusion 111 is flush to facilitate the arrangement of the supporting plate 30. Exemplarily, the protrusion 111 is extended in the width direction of the box body 10.

[0030] In some embodiments, Figure 2 As shown, the protrusion 111 is extended along the length direction of the box body 10, and the outer side of the bottom plate 11 corresponding to the protrusion 111 is formed as a recess 112. A rib plate 40 is arranged in the recess 112, and one end of the rib plate 40 extends out of the recess 112 and is fixedly connected to the support assembly 20.

[0031] By setting the protrusion 111 to extend along the length direction of the box body 10, the space of the recess 112 formed on the outer side of the bottom plate 11 when the protrusion 111 is formed can be cleverly utilized.
