Description

Technical Field

[0001] This utility model relates to the field of battery box technology, and more specifically, to a battery box with explosion-proof function. Background Technology

[0002] A battery case is a package or container used to hold and secure batteries. It is designed to protect and support the batteries while providing an interface for connecting to devices to ensure that the batteries can safely and reliably power the devices. Battery cases are typically made of plastic, metal, or other durable materials, and their internal structure and shape vary depending on the type and size of the batteries they contain.

[0003] Battery box explosion protection is an important safety consideration, especially when handling high-energy-density lithium batteries. Due to their high energy density and chemical reactivity, lithium batteries may burn or explode under certain conditions (such as overcharging, over-discharging, short circuits, high temperatures, etc.). These accidents can not only cause direct harm to personnel and equipment, but may also trigger secondary disasters such as fires and the release of toxic gases.

[0004] Existing battery boxes typically use a robust enclosure for explosion protection, without releasing internal gases. When the enclosure cannot withstand the internal gas pressure, the battery box may explode. The impact force of the explosion is also large, resulting in low safety and making it unsuitable for use. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a battery box with explosion-proof function.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Example:

[0029] Please see Figure 1-6An explosion-proof battery box includes: an explosion-proof battery box body 1, an explosion-proof battery box cover 2 detachably connected to one side of the explosion-proof battery box body 1, and an vent hole on one side of the outer wall of the explosion-proof battery box cover 2; and an explosion-proof venting assembly, which includes: an inner fixing seat 5, multiple adjusting components, a movable plate 9, an insertion seat 10, a sealing gasket 11, and an outer fixing seat 12. The inner fixing seat 5 is detachably connected to one side of the outer wall of the explosion-proof battery box cover 2, and each of the multiple adjusting components includes: a guide rod 6 and a mating plate. 7 and the pressure spring 8, the guide rod 6 is fixedly connected to one side of the outer wall of the inner fixed seat 5, the mating plate 7 is fixedly connected to one end of the guide rod 6, the pressure spring 8 is sleeved on the outer wall of the guide rod 6, and one end of the pressure spring 8 is fixedly connected to one side of the outer wall of the mating plate 7, the movable plate 9 is slidably sleeved between the outer walls of multiple guide rods 6, the probe seat 10 is fixedly connected to the bottom surface of the movable plate 9, the sealing pad 11 is fixedly connected to the bottom surface of the probe seat 10, and the outer fixed seat 12 is fixedly connected to one side of the outer wall of the explosion-proof battery box cover 2.

[0030] In a specific embodiment of this utility model, the battery is housed in the explosion-proof battery box body 1 and sealed by the explosion-proof battery box cover 2. Under normal use, the explosion-proof venting component does not allow gas exchange between the explosion-proof battery box body 1 and the outside. When the battery malfunctions, it generates heat and releases gas. At this time, the gas pressure inside the explosion-proof battery box body 1 rises, pushing the movable plate 9, the insertion seat 10, and the sealing pad 11 upward. The sealing pad 11 then moves out of the mating extension, and the gas is discharged. After the gas is discharged, the movable plate 9 moves under the pressure of the downward spring 8, and the sealing pad 11 closes the mating extension again, thus completing the reset and sealing during normal use. This allows for rapid pressure release in the event of a battery accident, reducing the impact of an explosion and achieving an explosion-proof effect, which is beneficial for long-term use.

[0031] Specifically, the top surface of the external fixing base 12 is provided with a mating extension, and the top surface of the mating extension is provided with an air outlet, which is mated with the sealing pad 11.

[0032] In this embodiment, the probe seat 10 is extended and accommodated, and the probe seat 10 is sealed by the probe seat 10 and the sealing pad 11, and can be depressurized in case of battery failure.

[0033] Specifically, the bottom surface of the external fixing seat 12 has two bottom sealing grooves 13, and a sealing ring 14 is provided between the inner walls of the two bottom sealing grooves 13.

[0034] In this embodiment, a sealing ring 14 is provided through the bottom sealing groove 13, which improves the sealing effect of the outer fixing seat 12 and the explosion-proof battery box cover 2.

[0035] Specifically, the bottom surface extension is provided with a probing extension 15, which is in conjunction with an air hole.

[0036] In this embodiment, the sealing effect of the outer fixing seat 12 and the explosion-proof battery box cover 2 is improved by extending the probe 15.

[0037] Specifically, a sealing liquid groove 16 is provided on the extended top surface, and the sealing liquid groove 16 and the sealing gasket 11 are fitted together.

[0038] In this embodiment, sealing liquid is provided through sealing liquid tank 16, and the sealing effect is improved by the cooperation of sealing liquid and sealing gasket 11.

[0039] Specifically, a display groove 3 is provided on one side of the outer wall of the explosion-proof battery box cover 2, and multiple side support ribs 4 are provided on both sides of the outer wall of the explosion-proof battery box body 1.

[0040] In this embodiment, a label is set in the display slot 3 to display the explosion-proof battery box cover 2, and the side support ribs 4 improve the strength of the explosion-proof battery box body 1 and enhance the explosion-proof effect.

[0041] Working principle: The battery is placed in the explosion-proof battery box body 1 and sealed by the explosion-proof battery box cover 2. Under normal use, the explosion-proof venting component does not allow gas exchange between the explosion-proof battery box body 1 and the outside. When the battery malfunctions, it generates heat and releases gas. At this time, the gas pressure inside the explosion-proof battery box body 1 rises, pushing the movable plate 9, the probe seat 10, and the sealing pad 11 upward. At this time, the sealing pad 11 moves out of the mating extension, and the gas will be discharged. After the gas is discharged, the movable plate 9 will move under the pressure of the downward spring 8, and the sealing pad 11 will close the mating extension again, thus completing the reset and sealing during normal use. It can quickly release pressure in the event of a battery accident, reduce the impact of an explosion, achieve the explosion-proof effect, and facilitate long-term use.

[0042] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
