[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1 As shown in Embodiment 1, a battery charging cabinet includes a cabinet body 1. The side panels of the charging cabinet have grooves, and the four corners of the multi-functional cover plate have protruding cylinders. A horizontal protrusion is located at the top of the vertical cover plate. The side panel grooves and the cover plate protrusions combine to form upper and lower layered areas. That is, the interior of the cabinet body 1 is divided into an upper charging area and a lower explosion-proof area. The upper charging area has several charging compartments and a control cavity. The control cavity contains a controller that can be operated via a touch screen. The controller can also be a charging control and communication integrated unit, serving as the intelligent control center of the entire device. It should be noted that the charging control and communication integrated unit uses existing control equipment, and this invention improves the equipment components but does not involve improvements to the circuitry or control program. This invention only controls the operation and shutdown of various electronic components through a PLC control system. Since the PLC control system is a mature automatic control system in industry, the circuitry and control program will not be described in detail here. The lower explosion-proof area includes an explosion-proof compartment 3 and a fire extinguisher compartment 4. The explosion-proof compartment 3 and the charging compartment 2 are arranged vertically and vertically, and an emergency passage 5 is provided between them. During charging, once the battery temperature in each compartment reaches a set value, the battery enters the explosion-proof compartment through the emergency passage. The fire extinguisher 41 in the fire extinguisher compartment 4 is connected to the explosion-proof compartment 3 to extinguish and cool the battery that falls into the explosion-proof compartment. Because the explosion-proof compartment is made of ceramic fiber material, the insulation temperature is ≥1200℃. The cabinet structure is made of fire-retardant material and has multiple independent charging compartments inside. The charging compartment 2 is equipped with a charging drawer 6 for supporting the battery. The charging drawer 6 is equipped with a pushing mechanism 7 that can push the battery to the emergency passage 5. In this embodiment, the pushing mechanism can be the simplest cylinder. Once the battery temperature in each compartment reaches the set value, the controller controls the pushing mechanism to push the battery to the emergency passage and fall into the explosion-proof compartment. Preferably, the charging drawer 6 can be equipped with a magnetic charging adapter 10 to accommodate different brands of lithium batteries. The charging cabinet supports parallel charging of multiple batteries, status monitoring, and timely handling of explosion-proof hazards, thus improving the safety of the charging cabinet.

[0030] like Figure 2 , 7 As shown in Embodiment 2, a battery charging cabinet is further optimized based on Embodiment 1. The charging drawer 6 includes a drawer body 61, which can be pulled out and put into the charging compartment 2 for quick battery access. The bottom of the drawer body 61 is provided with a partition 62, in which the battery is placed on the partition. The front panel of the drawer body 61 is provided with a viewing window 63 for easy observation of the internal charging status.

[0031] like Figure 8 , 9 As shown, the pushing mechanism 7 in this embodiment includes a push plate 71 and a guide rod 72 disposed at the bottom of the drawer body 61. One or more guide rods 72 can be provided as needed; this embodiment uses two guide rods as an example. The two guide rods are disposed below the partition. The push plate can be composed of a U-shaped frame and an acrylic transparent perforated plate. The push plate can move along the guide rods. The push plate 71 is slidably disposed on the guide rod 72 and above the partition 62, so as to push the battery on the partition into the emergency passage. A groove is provided between the partition 62 and the drawer body 61 for the push plate 71 to move, avoiding interference. The push plate 71 is connected to a pushing power component disposed inside the drawer body 61. The pushing power component can be a small cylinder, an electromagnetic push rod, or other power components; used to push the push plate to move.

[0032] like Figure 10 , 11As shown, in this embodiment, as a preferred solution: the pushing power component includes a trigger release component 73 and a first spring 74 sleeved on the guide rod 72. One end of the first spring 74 is connected to the push plate 71, and the other end is connected to the spring cylinder 75. The spring cylinder 75 is fixed to the front panel of the drawer body 61. In the normal locking state, the first spring is in a compressed state and located in the spring cylinder. At this time, the push plate is close to the front panel of the drawer. The trigger release assembly 73 includes an L-shaped base 731 located at the bottom of the drawer body 61 and below the partition 62. The L-shaped base 731 has an electromagnetic push-pull rod 732 and a release rod 733. The electromagnetic push-pull rod is horizontally positioned on the L-shaped base. The release rod 733 is hinged to the L-shaped base 731 at its front center via a pin. One end of the release rod 733 is connected to the ball joint 734 of the electromagnetic push-pull rod 732, and the other end has a locking protrusion 735, which corresponds to a locking hole 65 on the partition 62. When the trigger release assembly 73 is in the locked state, the locking protrusion 735 extends upwards out of the locking hole 65 to secure the push plate 71. In an emergency requiring the battery to be pushed to the emergency exit, the electromagnetic push-pull rod retracts the release rod 733 via the ball joint 734. At this time, the locking protrusion 735 retracts downwards, disengaging from the locking hole 65. Simultaneously, the first spring is released, pushing the push plate and the battery towards the emergency exit. Then, the electromagnetic push-pull rod extends in the opposite direction, triggering the release component to reset. For example... Figure 2 , 3 As shown, the top plate 21 of the charging compartment 2 is equipped with an infrared temperature probe 22, which can be an infrared sensor to detect the battery temperature. Once the temperature stabilizes above the set value, the pushing mechanism 7 will activate. The back plate 25 of the charging compartment 2 is equipped with a cooling fan 26 to dissipate heat from the battery in a timely manner. The back plate 25 of the charging compartment 2 is hinged to the top plate 21 of the charging compartment 2. That is, the back plate is connected to the top plate through a horizontally set pin. Under normal conditions, it can dissipate heat from the battery by airflow, and in case of an emergency, it can push the battery to the emergency passage without affecting its movement.

[0033] like Figure 7As shown in Embodiment 3, a battery charging cabinet is further optimized based on Embodiments 1 or 2. The magnetic charging adapter 10 includes a magnetic wire interface 24 disposed on the front panel 23 of the charging compartment 2 and a magnetic socket 64 disposed on the front panel of the drawer body 61. The front panel 23 is provided with a hollow wire sleeve for the passage of wires. The wires are electrically connected to the magnetic wire interface for power supply and signal transmission. The magnetic wire interface 24 and the magnetic socket 64 are magnetically matched and can supply power to the magnetic socket. The magnetic socket 64 can be provided with a charging indicator light and a release status indicator light for the trigger release component. A magnetic charging cable 27 is inserted into the magnetic wire interface 24, and the charging end of the magnetic charging cable 27 is detachably connected to a charging adapter 28. The charging adapter can be adapted to different types of lithium batteries.

[0034] Specifically, such as Figure 12 As shown, the charging adapter 28 includes a housing 281, which is formed by an upper cover and a lower cover with staggered protrusions and grooves around its perimeter. Guide grooves 282 are provided on the front and rear sides of the housing 281. Electrode pins 283 are provided inside the housing 281. In this embodiment, two electrode pins are provided, with their front and rear ends extending out of the corresponding guide grooves 282. An axial limiting ring 2810 is provided on the electrode pin 283, with the outer diameter of the limiting ring being larger than the width of the guide groove. This restricts the electrode pin to move only laterally along the guide groove and prevents longitudinal axial movement. The rear end of the electrode pin 283 is connected to the DC male connector on the magnetic charging cable via a DC female adapter cable. A U-shaped limiting block 285 is engaged with the electrode pin 283, and a limiting adjustment bolt 286 is hinged to the U-shaped limiting block 285. The limiting adjustment bolt 286 is threadedly engaged with a threaded hole 287 on the housing 281. The limit adjustment bolt 286 rotates, causing the electrode pin 283 to move laterally along the guide groove, adjusting the distance between the two electrode pins to accommodate the charging of different battery models.

[0035] In this preferred embodiment, the specific structure of the U-shaped limiting block 285 hinged with the limiting adjustment bolt 286 is as follows: A T-slot 288 is provided on the U-shaped limiting block 285, and a rotatable disc 289 is provided within the T-slot 288. The disc 289 is fixedly connected to the end of the limiting adjustment bolt 286. When the limiting adjustment bolt rotates, the disc rotates within the T-slot, causing the U-shaped limiting block to move laterally without rotation. Rotating the bolt causes the limiting slider to move the electrode pin horizontally to adjust the spacing. Limiting rings are provided at both ends of the charging pin inside the box to prevent longitudinal displacement. The contact portion between the electrode pin and the battery electrode adopts a semi-cylindrical design. When the contact between the pin and the battery electrode slot is not tight enough, the electrode pin can be rotated to achieve effective contact by deflecting the diameter of the semi-cylindrical part, thus avoiding incomplete electrode connection. Users place the lithium battery in any compartment and preferentially connect it to the battery's charging port using a magnetic DC male charging cable. If a different interface is encountered, an adjustable-pitch electrode adapter pin is used to correspond to the appropriate contact electrodes. By adjusting the spacing of the left and right bolts and the angle of the electrode pins, the battery's electrode contacts are ensured to make tight contact with the adjustable-pitch electrode adapter pins, forming an effective connection and conducting current. The charging control and communication unit features a MOSET+ integrated IC combination to prevent reverse connection of the battery charging electrodes. An indicator light on the outer panel of the drawer will illuminate when the battery and charging cable are correctly connected and conducting. In actual use, battery information can also be programmed by attaching an individual QR code to each battery. The QR code is scanned by a camera to read the battery information, and the MCU calls the preset charging curve to initiate fast charging.

[0036] like Figure 4 , 6 As shown, in this embodiment, the emergency passage 5 is equipped with a guide bar 51 and a horizontal flap 52. The guide bar 51 has a sloping cross-section, allowing the battery to smoothly enter the explosion-proof compartment below the emergency passage. The horizontal flap 52 is located below the guide bar 51. A horizontal shaft 53 is provided at one end of the horizontal flap 52 near the back panel of the cabinet 1. The horizontal shaft is rotatably connected to the emergency passage 5. A flipping rod 54 is provided on the horizontal shaft 53. A second spring 55 is connected to the flipping rod 54. A spring force adjusting bolt 56 is connected to the second spring 55. The spring force adjusting bolt 56 is threadedly connected to the ear seat 57 located at the lower part of the cabinet 1; it is used to adjust the spring tension. The horizontal flap 52 is an explosion-proof plate that is always closed by the spring tension; the flap will only tilt downwards and open when an external force from top to bottom exceeds the spring tension.

[0037] like Figure 5As shown, in this embodiment, the explosion-proof compartment 3 is equipped with an explosion-proof drawer 8, a square tube sleeve 31 located above the explosion-proof drawer 8, and a fire extinguishing pipe 32. A smoke and temperature integrated sensor 33 is connected to the square tube sleeve 31. The smoke and temperature integrated sensor integrates smoke detection and temperature measurement functions, and can be an integration of a smoke detection sensor and a temperature measurement sensor. The inlet end of the fire extinguishing pipe 32 is connected to the fire extinguisher 41, and the outlet end of the fire extinguishing pipe 32 is equipped with an electromagnetic nozzle 34 corresponding to the explosion-proof drawer 8. The electromagnetic nozzle 34 is used for the uniform spraying of the fire extinguisher. The fire extinguisher can be a carbon dioxide fire extinguisher. The outlet end of the carbon dioxide fire extinguisher is equipped with a pressure gauge for daily monitoring of the gas pressure. A pressure reducing valve is connected to the outlet, which is then connected to a gas solenoid valve to achieve pressure stabilization and avoid excessive pressure impact on the solenoid valve, ensuring that the carbon dioxide gas is evenly sprayed in the explosion-proof fire extinguishing compartment for effective utilization and preventing overflow.

[0038] Furthermore, this invention can also be based on an MCU (microcontroller) charging management unit to support fast / slow charging mode switching. Real-time monitoring of voltage, current, and temperature prevents overcharging, over-discharging, and short circuits. During use, the user places the lithium battery in any compartment and preferentially connects it to the battery's charging port using a magnetic DC male charging cable. If different interface types are encountered, an adjustable-pitch electrode adapter is used to connect the corresponding electrodes. By adjusting the spacing of the left and right bolts and the angle of the electrode pins, the battery's electrode contacts are tightly clamped to form an effective connection and conduct current. The charging control and communication unit is equipped with a MOSET+ integrated IC combination to prevent reverse connection of the battery charging electrodes. When the battery and charging cable are correctly connected, the indicator light on the outer panel of the drawer will illuminate. When the battery temperature exceeds the limit detected by the infrared camera temperature sensor in the charging compartment, it automatically switches to slow charging and activates the fan for heat dissipation. When the infrared temperature sensor in the charging compartment detects an abnormal battery temperature, it triggers the electromagnetic push mechanism in the charging drawer to release the push plate, pushing the battery and disconnecting the magnetic cable from the magnetic interface on the multi-functional integrated cover. This achieves power cut-off and separation, and the battery is then transported to the explosion-proof compartment. If the battery temperature continues to rise or smoke is emitted, the sensor triggers, and the carbon dioxide electromagnetic inlet in the explosion-proof compartment is energized to release gas for fire extinguishing and cooling. When the charging drawer returns to its original position, the inner magnetic cable connector and the magnetic socket are magnetically attracted. After the contacts are connected, the control module measures the resistance value of the push-pull solenoid valve coil. If the resistance value is less than the set value, the indicator light on the outside of the drawer illuminates. By measuring the coil resistance of the solenoid valve, the control module determines whether the magnetic cable connector is effectively and correctly connected and whether the electromagnetic push-pull rod is functioning properly, preventing accidental operation that could cause the push mechanism to malfunction.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
