[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] Please refer to Figures 1 to 10 According to an embodiment of the present invention, the storage box includes a top cover 1 and a box body 2. The box body 2 has an upward-opening inner cavity 20. One side of the top cover 1 is rotatably connected to the box body 2. Closing or opening the top cover 1 can cover or open the inner cavity 20.

[0026] The upper cover 1 includes an upper cover body 11, a pair of connecting portions 12 extending downward from one side of the upper cover body 11, and a pair of inserts 13 connected to the pair of connecting portions 12 and extending downward. Each insert 13 includes an insert body 131 and a pair of elastic latching arms 132. The pair of elastic latching arms 132 are respectively disposed on both sides of the insert body 131. The top end of each elastic latching arm 132 is connected to the insert body 131, and the bottom end of each elastic latching arm 132 is provided with a first latching portion 133.

[0027] The top surface of the box body 2 has a pair of insertion holes 23, and each insertion hole 23 has a second latching part 233 on its two opposite holes. A pair of insert pieces 13 are inserted into the pair of insertion holes 23 respectively, and the first latching part 133 of the pair of elastic latching arms 132 of each insert piece 13 is latched to the two second latching parts 233 of the insertion hole 23 respectively. In this embodiment, the first latching part 133 is a hook head that is provided at the bottom end of the elastic latching arm and protrudes outward, and the second latching part 233 is a slot provided in the hole wall of the insertion hole. The hook head is embedded in the slot, which can prevent the insert piece 13 from detaching upward from the insertion hole 23 and restrict the left and right movement of the pair of elastic latching arms, effectively ensuring the reliable connection between the top cover and the box body. Optionally, the insert body 131 is inverted convex, and the top ends of the pair of elastic latching arms 132 are respectively connected to the two shoulders 134 of the inverted convex insert body 131.

[0028] In this embodiment, the thickness of the connection between each connecting part 12 and the corresponding insert is 0.2mm to 0.3mm to ensure the flexible flipping of the upper cover 1. Preferably, the upper cover 1 is made of plastic, and the upper cover body 11, a pair of connecting parts 12 and a pair of inserts 13 are integrally injection molded.

[0029] In this embodiment, the storage box is a power tool storage box, which also includes an inner liner 3, a temperature sensor 4, a cooling fan 5, a controller (not shown in the figure), and a power bank 7.

[0030] A liner 3 is disposed within the housing 2. The liner 3 has a receiving slot 30 for accommodating the power tool. A temperature sensor 4 is disposed on the bottom surface of the receiving slot 30, which also has ventilation holes 301. A cooling fan 5 is disposed below the liner 3 and opposite the receiving slot 30. The cool air blown by the cooling fan 5 can pass through the ventilation holes 301 to cool the power tool placed in the receiving slot 30. The output of the temperature sensor 4 is connected to the input of a controller, and the output of the controller is connected to the control of the cooling fan 5 to control its start and stop. When the temperature sensor 4 detects that the temperature of the power tool exceeds the set temperature, the controller activates the cooling fan 5 to cool the tool through the ventilation holes 301 until the temperature of the power tool drops below the set temperature, thus ensuring the safety of the power tool. Preferably, the temperature sensor 4 is an ultra-thin temperature sensor.

[0031] A power bank 7 is located below the inner liner 3 to power the temperature sensor 4 and the cooling fan 5. Specifically, the cooling fan 5 and the power bank 7 are respectively located on the bottom surface of the inner cavity 20 of the housing 2. The bottom surface of the inner cavity 20 has a first positioning structure for positioning the cooling fan 5 and a second positioning structure for positioning the power bank 7. The second positioning structure includes multiple ribs 201 that surround the power bank 7 to achieve positioning. In this embodiment, there are four ribs 201. The first positioning structure includes multiple positioning posts 202 that pass through corresponding positioning holes 52 on the cooling fan 5 to position the cooling fan 5. In this embodiment, there are four positioning posts 202.

[0032] The side of the housing 2 is provided with an input charging port 241, an output charging port 242, and a power bank switch 243. The input charging port 241 is electrically connected to the power bank 7 to charge it; optionally, the input charging port 241 is a Type-C interface. The output charging port 242 is electrically connected to the power bank 7 and is used to charge power tools; optionally, the output charging port 242 is a USB interface. The power bank switch 243 is used to control whether the power bank 7 is working.

[0033] In some specific applications, the aforementioned power tool is an electric screwdriver 8. After prolonged use, especially in high ambient temperatures (e.g., summer), the electric screwdriver generates significant heat (tested to reach up to 65°C). This not only damages internal components but also prevents timely charging of the screwdriver while it is hot (charging at high temperatures poses a significant safety hazard). Allowing it to cool down naturally takes a considerable amount of time. Therefore, monitoring and cooling the electric screwdriver's temperature is crucial.

[0034] The main heat source for the electric screwdriver 8 comes from the front-end motor and gearbox, with a smaller portion originating from the rear-end circuit board and battery cells. Therefore, in this embodiment, the temperature sensor 4 is located near the front end of the electric screwdriver 8. After use, the electric screwdriver 8 is placed back into the storage compartment 30 of the storage box, and the power bank switch 243 is turned on to activate the power bank 7. At this time, the outer casing of the electric screwdriver 8 comes into contact with the temperature sensor 4, thereby monitoring the temperature of the electric screwdriver's outer casing. When the temperature of the electric screwdriver 8 exceeds the preset temperature stored in the controller, the controller controls the cooling fan 5 to turn on, drawing air in through the ventilation hole 301 to dissipate heat from the electric screwdriver. When the temperature drops to the preset temperature, the controller controls the cooling fan 5 to stop, and the power bank 7 is powered off.

[0035] When taking the electric screwdriver 8 and its storage box outdoors for work, the electric screwdriver typically uses a 1500-2000mAh battery, resulting in relatively limited battery life. To improve battery life, a power bank 7 is needed to charge it. To charge, turn on the power bank switch 243 and connect the electric screwdriver 8 to the output charging port 242 using the data cable 9. For daily use, the power bank 7 is charged via the input charging port 241.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
