Description

Technical Field

[0001] The present invention belongs to the technical field of charging cabinets, and in particular relates to an intelligent management cabinet for charging and storing handheld power tools. Background Art

[0002] The smart management cabinet for charging and storing handheld power tools is a device that combines the Internet of Things, battery management systems and intelligent monitoring technologies. Through the cabinet design that integrates multiple charging positions, it can charge the batteries of multiple power tools at the same time, reducing the phenomenon of scattered charging. It aims to solve the safety risks and management efficiency issues of traditional charging methods.

DETAILED DESCRIPTION

[0033] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0034] like Figures 1-8 As shown, an intelligent management cabinet for charging and storing handheld power tools includes an intelligent management cabinet body 1, which includes a drawer-type power supply unit 11, a human-computer interaction interface 12 and multiple charging cabinets 13. The cabinet door of the charging cabinet 13 is provided with an electromagnetic lock 131, and the cabinet door of the charging cabinet 13 is embedded with tempered glass to facilitate observation of the internal situation of the charging cabinet. A charging plug board 132 is provided in the charging cabinet 13. A distribution component is installed inside the drawer-type power supply unit 11, which supplies power to the entire device. The drawer-type power supply unit 11 is embedded with tempered glass to facilitate observation of the internal situation of the charging cabinet. In addition, the power supply unit adopts a drawer type for easy maintenance. The human-computer interaction interface 12 includes a camera and a touch panel. The human-computer interaction interface 12 is used to control the opening and closing of each electromagnetic lock 131. During specific use, the user first identifies his identity through the camera of the human-computer interaction interface 12. After the identity is confirmed, the user selects an idle charging cabinet 13 in the pop-up dialog box. Then the human-computer interaction interface 12 opens the corresponding charging cabinet 13 according to the user's selection for the user to store or charge.

[0035] The intelligent management cabinet body 1 is provided with a fire box 21 and a fire passage 22. A carbon dioxide fire extinguisher 23 is installed in the fire box 21. A guide pipe 24 is fixed in the fire passage 22. The guide pipe 24 is connected to the carbon dioxide fire extinguisher 23. A plurality of branch pipes 241 are provided on the guide pipe 24. The plurality of branch pipes 241 lead to the drawer-type power supply unit 11, the human-machine interface 12 and the charging cabinet 13 respectively. A solenoid valve 242 is provided on each branch pipe 241. A smoke alarm 3 is provided in the drawer-type power supply unit 11, the human-machine interface 12 and the charging cabinet 13. The circuit connection between the smoke alarm 3 and the adjacent solenoid valve 242 is in series. When the smoke alarm 3 sounds an alarm, it can trigger the corresponding solenoid valve 242 to open and perform a fire extinguishing operation. During use, if the line is on fire due to problems such as line aging or short circuit, the smoke generated by the fire will trigger the smoke alarm 3, and the smoke alarm 3 will sound an alarm. When the smoke alarm 3 is triggered, the solenoid valve 242 connected in series with it will be opened synchronously, so that the carbon dioxide in the carbon dioxide fire extinguisher 23 can quickly enter the burning charging cabinet 13 to perform a fire extinguishing operation, thereby preventing the fire from spreading and reducing safety hazards.

[0036] The fire passage 22 is provided with a hidden inspection door 25, which includes a door panel 251 that can be detachably fixed to the fire passage 22. A through slot 252 is provided in the middle of the door panel 251, and an installation slot 253 is provided on the outer side of the through slot 252. A sealing plate 254 can be detachably fixed in the installation slot 253. After the sealing plate 254 is installed and fixed, its surface is flush with the surface of the door panel 251. Specifically, when the device is in normal use, the inspection door 25 is flush with the door panel 251 and is in a hidden state to prevent the user from frequently pulling the inspection door 25, which may cause the device to shake or the door panel 251 to deform. When the fire passage 22 needs to be inspected regularly, the screws fixing the sealing plate 254 and the door panel 251 are unscrewed, and the sealing plate 254 and the door panel 251 are removed to maintain the fire passage 22.

[0037] A heat dissipation assembly is provided in the charging cabinet 13. The heat dissipation assembly includes two heat dissipation windows 41 and a semiconductor cooler 42. The two heat dissipation windows 41 are symmetrically arranged in the charging cabinet 13. The semiconductor cooler 42 is fixed to the top plate of the charging cabinet 13. Multiple rotating shafts 43 are rotatably connected to the heat dissipation windows 41 through torsion springs. Shielding blades 431 are fixed to the rotating shafts 43. When the torsion springs are in the natural state, the shielding blades 431 close the heat dissipation windows 41.

[0038] It is worth mentioning that, since the drawer-type power supply unit 11 and the human-machine interaction interface 12 are in working state for a long time, and both have higher requirements for working temperature, the temperature control in the drawer-type power supply unit 11 and the human-machine interaction interface 12 is only performed by the semiconductor cooler 42 (not shown in the figure), and the charging cabinet 13 has certain requirements for the charging temperature only when charging. Therefore, in order to reduce the operating cost of the equipment, the charging cabinet 13 adopts the heat dissipation window 41 and the semiconductor cooler 42 to cooperate with each other for temperature control. Specifically, when the charging cabinet 13 is in an idle state, the charging cabinet 13 is in a power-off state, and the internal semiconductor cooler 42 will not work. The heat dissipation window 41 appropriately controls the temperature in the charging cabinet 13 by adjusting the angle of the shielding blade 431. For example, in summer, when the ambient temperature is high, the heat dissipation window 41 is opened to a greater extent, making it easier for the air in the charging cabinet 13 to circulate, thereby reducing the temperature in the charging cabinet 13. For example, in winter, when the ambient temperature is low, the heat dissipation window 41 is completely closed to reduce the heat loss in the charging cabinet 13.

[0039] The charging cabinet 13 is provided with a driving assembly for driving the shielding blade 431 to rotate. The driving assembly includes a shell 44 fixed in the charging cabinet 13, a sleeve 441 is provided in the shell 44, a slide rod 442 is provided in the sleeve 441, a limit plate 443 is provided at the bottom of the slide rod 442, the limit plate 443 is sealingly and slidingly connected to the sleeve 441, and a thermal expansion medium is installed in the sleeve 441 below the limit plate 443. In this embodiment, the thermal expansion medium is mercury, and a spring 444 is sleeved on the slide rod 442 between the limit plate 443 and the top of the sleeve 441. A U-shaped plate 445 is fixed to the top of the slide rod 442, and extrusion plates 446 are fixed on both sides of the U-shaped plate 445. A column gear 432 is fixed to the bottom of the rotating shaft 43, and a rack 447 is slidably connected in the shell 44, and the ends of the rack 447 and the extrusion plate 446 that are close to each other are provided with mutually matching bevels;

[0040] A first conductive sheet 4451 and a second conductive sheet 4452 are fixed to the top and bottom of the U-shaped plate 445, respectively. A third conductive sheet 448 and a fourth conductive sheet 449 are provided on the top and bottom of the housing 44, respectively. When the first conductive sheet 4451 and the third conductive sheet 448 are connected, and when the second conductive sheet 4452 and the fourth conductive sheet 449 are connected, the semiconductor cooler 42 can be energized. When the semiconductor cooler 42 is energized in two ways, the current flowing through the semiconductor cooler 42 is in opposite directions. Specifically, when the first conductive sheet 4451 and the third conductive sheet 448 are connected, the semiconductor cooler 42 cools, and when the second conductive sheet 4452 and the fourth conductive sheet 449 are connected, the semiconductor cooler 42 heats.

[0041] It is worth mentioning that when the rack 447 just contacts the inclined surface of the extrusion plate 446, the temperature inside the charging cabinet 13 is 30°C, which is a temperature range suitable for charging and does not require heat dissipation. At this time, the heat dissipation window 41 is in a closed state. When there is an electric tool in the charging cabinet 13 for charging, charging will generate heat, which will increase the temperature inside the charging cabinet 13. The mercury in the sleeve 441 will expand due to the heat, thereby moving the extrusion plate 446 upward, and then driving the rack 447 to move. The action of the column gear 432 causes the shaft 43 and the shielding blade 431 to rotate, thereby opening the heat dissipation window 41 and starting to dissipate heat through the heat dissipation window 41. When the rack 447 contacts the side wall of the extrusion plate 446, the heat dissipation window 4 1 is fully opened, and in this contact state, the extrusion plate 446 moves up and the rack 447 no longer moves, and the heat dissipation window 41 still maintains the maximum opening state. When the extrusion plate 446 moves up to the first conductive plate 4451 and is connected to the third conductive plate 448, the semiconductor refrigerator 42 starts to cool for a preset time to assist in cooling. In addition, if the initial temperature in the charging cabinet 13 is lower than 10°C during charging, the second conductive plate 4452 and the fourth conductive plate 449 are initially in a connected state. When the user selects the charging cabinet 13, the corresponding charging cabinet 13 is powered on, and the semiconductor refrigerator 42 starts to heat for a preset time, so that the temperature in the charging cabinet 13 is quickly raised to a temperature range suitable for charging.

[0042] The working principle of the present invention is as follows:

[0043] When in use, the user first identifies himself through the camera of the human-computer interaction interface 12. After the identity is confirmed, the user selects an idle charging cabinet 13 in the pop-up dialog box. Then the human-computer interaction interface 12 opens the corresponding charging cabinet 13 according to the user's selection for the user to store or charge;

[0044] During use, if a fire occurs in a circuit due to circuit aging, short circuit, or other problems, the smoke generated by the fire will trigger the smoke alarm 3, which will sound an alarm. When the smoke alarm 3 is triggered, the solenoid valve 242 connected in series with it will be opened synchronously, allowing the carbon dioxide in the carbon dioxide fire extinguisher 23 to quickly enter the charging cabinet 13 on fire to extinguish the fire, thereby preventing the fire from spreading and reducing safety hazards.

[0045] During charging, heat is generated, and the mercury in the sleeve 441 expands due to the heat, causing the extrusion plate 446 to move upward. When the temperature in the charging cabinet 13 reaches 30°C, the extrusion plate 446 contacts the inclined surface of the rack 447. As the temperature in the charging cabinet 13 continues to rise, the mercury in the sleeve 441 continues to expand due to the heat, causing the extrusion plate 446 to continue to move upward, thereby driving the rack 447 to move and causing the shielding blade 431 to rotate, thereby opening the heat dissipation window 41 and starting to dissipate heat through the heat dissipation window 41. When the rack 447 contacts the side wall of the extrusion plate 446, the heat dissipation window 41 is fully opened, and in this contact state, the extrusion plate 446 moves upward and the rack 447 no longer moves, and the heat dissipation window 41 still remains in the maximum open state. When the extrusion plate 446 moves upward to connect with the first conductive sheet 4451 and the third conductive sheet 448, the semiconductor refrigerator 42 starts to cool for a preset time to perform auxiliary cooling.

[0046] In addition, if the initial temperature inside the charging cabinet 13 is lower than 10°C during charging, the second conductive plate 4452 and the fourth conductive plate 449 are initially in an on state. When the user selects the charging cabinet 13, the corresponding charging cabinet 13 is powered on, and the semiconductor cooler 42 starts heating for a preset time, so that the temperature inside the charging cabinet 13 is quickly raised to a temperature range suitable for charging. By using the heat dissipation window 41 and the semiconductor cooler 42 in conjunction with each other, the operating cost of the equipment is reduced and the waste of electricity resources is avoided.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
