Description

Technical Field

[0001] The invention relates to the technical field of protection boxes, in particular to a charging safety protection box for portable electronic devices. Background Art

[0002] In portable electronic devices, battery capacity is one of the key indicators that affect the use of electronic devices. Large-capacity lithium-ion batteries are now commonly used as power sources for portable electronic devices. Due to their own reasons, lithium-ion batteries have relatively poor safety performance. Abnormal temperature rise during charging and discharging can cause the battery to catch fire and explode, so they need to be placed inside a protective box to achieve safety protection. Existing portable electronic device charging safety protection boxes still have many problems during use. The specific problems are as follows:

[0003] 1. The existing portable electronic device charging safety protection box cannot cut off the power supply in time during use, so the disaster cannot be controlled in time;

[0004] 2. Existing portable electronic device charging safety protection boxes cannot release pressure when a fire occurs during use, causing an explosion in a high-pressure environment that will damage the electronic equipment;

[0005] 3. The existing portable electronic device charging safety protection box cannot adjust the internal compartments of the protection box during use, making it inconvenient to use;

[0006] 4. The existing portable electronic device charging safety protection box has no buffer structure inside during use, and when an explosion occurs, the damage rate of the electronic device increases. Summary of the invention

[0007] The purpose of the present invention is to provide a portable electronic device charging safety protection box to solve the problems raised in the above background technology, such as failure to cut off the power supply in time, failure to release pressure when a fire occurs, and failure to adjust the internal compartments of the protection box.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a portable electronic device charging safety protection box, comprising a protection box body, a side door, a partition plate, a protective cover and an alarm controller, a fire sensor is installed on one side of the top end of the outer side of the protection box body, and a pressure relief chamber is fixedly connected to one side of the outer side of the protection box body, a plurality of partition plates are movably connected inside the protection box body, and a plurality of sliding sleeves are fixedly connected on both sides of the partition plates, a side door is movably connected to one side of the outer side of the protection box body, a protective cover is fixedly connected to one side of the outer side of the protection box body, and an alarm controller is installed in the middle position of one side of the outer side of the protection box body.

[0009] Preferably, both ends of the interior of the protection box body are fixedly connected with sliding rods, and a power-off protector is installed on one side of the bottom end of the exterior of the protection box body.

[0010] Preferably, a baffle is provided on one side of the bottom end of the protection box body, and a vent hole is provided at a middle position of one side inside the protection box body.

[0011] Preferably, a spiral sleeve is fixedly connected to one side of the outer part of the sliding sleeve, and the inner part of the spiral sleeve is movably connected to a limiting bolt, the inner part of the spiral sleeve is provided with an internal thread, and the outer part of the limiting bolt is provided with an external thread matching the internal thread of the spiral sleeve.

[0012] Preferably, a plurality of hollow grooves are provided on both sides of the interior of the partition plate, and a spring is fixedly connected inside, a sliding block is slidably connected to one side of the spring, and a buffer plate is fixedly connected to one side of the sliding block.

[0013] Preferably, a fire extinguishing agent cylinder is arranged on one side inside the protective cover, and a fire extinguishing agent nozzle is fixedly connected to one side of the top of the fire extinguishing agent cylinder.

[0014] Preferably, a solenoid valve is installed on one side of the fire extinguishing agent nozzle, and a nozzle is fixedly connected to one side of the fire extinguishing agent nozzle.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) This portable electronic device charging safety protection box has a fire sensor installed on one side of the top of the protection box body. When an event that meets the alarm condition occurs, the fire sensor will transmit a signal to the alarm controller, so that the alarm controller will immediately cut off the power supply of the electronic device to prevent the situation from further deteriorating. At the same time, it will output an opening signal of the solenoid valve, and the fire extinguishing agent cylinder will start to spray to extinguish the fire, control the fire and prevent the disaster from expanding. When the power outage and fire extinguishing measures fail to achieve the goal of cooling and extinguishing the fire, or even cause the battery of the charging device to explode due to high temperature, the protection box body will prevent the flame and explosion debris from splashing, thereby blocking the disaster from spreading further.

[0017] (2) This portable electronic device charging safety protection box has a pressure relief chamber on one side of the outside of the protection box body. When an explosion occurs, part of the high-pressure gas enters the pressure relief chamber through the vent between the protection box body and the pressure relief chamber, thereby reducing the air pressure in the protection box body and protecting the protection box body from damage. In addition, the alarm controller will control the power-off protector to cut off the main power supply to prevent the high temperature of the fire from igniting the cable and causing the disaster to spread, thereby protecting the electronic equipment from damage to a certain extent.

[0018] (3) This portable electronic device charging safety protection box has sliding sleeves fixedly connected on both sides of the partition plate. The partition plate can slide inside the sliding rod through the sliding sleeves, so that the partition plate can be adjusted to a suitable position, so that the interior of the protection box body can be divided into spaces of different sizes by the partition plate. At this time, the limit bolt can be rotated inside the spiral sleeve so that the limit bolt can contact the sliding rod, thereby limiting the partition plate. The position of the partition plate can be adjusted as needed, which facilitates the use of the box.

[0019] (4) This portable electronic device charging safety protection box has multiple hollow grooves arranged inside the partition plate. When an explosion occurs inside the protection box body, the impact force will push the buffer plate to move, so that the buffer plate will push the sliding block to slide inside the hollow groove and squeeze the spring, causing the spring to generate a reaction force. This reaction force will make the partition plate have a buffering effect, thereby reducing the damage rate of the electronic equipment when an explosion occurs. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] A plurality of hollow grooves 504 are arranged on both sides of the partition plate 5, and a spring 505 is fixedly connected inside. A sliding block 506 is slidably connected to one side of the spring 505, and a buffer plate 507 is fixedly connected to one side of the sliding block 506. The spring 505 generates a reaction force, and this reaction force makes the partition plate 5 have a buffering effect, thereby reducing the damage rate of the electronic equipment when an explosion occurs;
