[0030] A charging compartment, the charging compartment comprising a rear panel 11 arranged at the rear end, a top panel 12 arranged at the top, and at least two side panels arranged at both sides, the rear end of the top panel 12 is connected to the top end of the rear panel 11, the rear panel 11 is connected to the two side panels, and the top panel 12 is also connected to the two side panels;

[0031] A charging component, which is inserted into the charging compartment and can be an existing lithium battery charging component or a charging and discharging component;

[0032] A safety door 3 is connected to the charging compartment. The safety door 3 is arranged at the front end of the charging compartment. The safety door 3 is a transparent safety door 3.

[0033] In this embodiment, the safety door 3 is a transparent safety door 3, so that the charging status of the battery in the working compartment can be observed.

[0034] As an optional implementation, the charging compartment is also a transparent charging compartment, so as to better observe the charging status of the battery in the working compartment. The material of the transparent safety door 3 and the transparent charging compartment can be transparent acrylic material or other transparent materials.

[0035] In this embodiment, Figure 4 As shown, the charging assembly includes a positive cable electrode 21 and a negative cable electrode 22, and the positive cable electrode 21 and the negative cable electrode 22 are inserted into the charging compartment, and the positive cable electrode 21 and the negative cable electrode 22 are connected to the charging compartment in a sliding manner. The positive cable electrode 21 and the negative cable electrode 22 are used to charge the battery; the positive cable electrode 21 and the negative cable electrode 22 are both provided with a pole head 23 for connecting to a battery module for power supply. Optionally, the pole head 23 can be an existing charging head, or the quick-plug pole head 23 of the present application can be used.

[0036] The quick-plug pole head 23 of the present application adopts a quick-plug design, which is convenient for the operator to quickly connect and disconnect, thereby improving work efficiency. Specifically, the quick-plug pole head 23 includes a pole head 23 body, and the interior of the pole head 23 body is provided with 5 circles of copper-plated gold-dot-type card points, which are evenly distributed inside the pole head 23 body to form a ring array, which not only provides additional stability and fixing effect during connection, and enhances the firmness of the connection, but also can fully contact the pole studs of the lithium battery module to ensure the stability and reliability of the electrical connection.

[0037] The entire quick-plug pole head 23 has high structural strength and is made of pure copper to meet the needs of high current charging and discharging. In addition, the main body of the pole head 23 is covered with an insulating rubber to ensure the safety of the operator during the connection or disconnection process. Considering the different types and sizes of 48V modules, the quick-plug pole head 23 can be retracted using the existing gold-plated dot-type card point, and has a certain degree of adjustability to improve its compatibility.

[0038] The positive electrode 21 and the negative electrode 22 of the cable pass through the rear plate 11; a through hole is also provided on the rear plate 11, and the through hole is provided between the positive electrode 21 and the negative electrode 22 of the cable to facilitate the passage of a low-voltage communication line adapted to the module; at least two holes are reserved on the top plate 12 to facilitate the adjustment of the position of the positive and negative cables.

[0039] The charging warehouse also includes a bottom support plate 15, which is arranged on the bottom outer side of the charging warehouse. At least two bottom support plates 15 are provided to support the structure of the entire working warehouse; the side panel includes a left side panel 13 and a right side panel 14, and the two bottom support plates 15 are respectively connected to the left side panel 13 and the right side panel 14, and are arranged on the left and right sides of the charging warehouse.

[0040] This embodiment does not provide a bottom plate, but only provides a bottom support plate 15 on the outside of the charging compartment to support the working compartment, so that after the charging assembly is connected to the battery to be charged, the user only needs to place the charging compartment on the battery to be charged, without having to place heavier batteries in the charging compartment, which is convenient for users to charge.

[0041] The safety door 3 is rotatably connected to the charging compartment. In this embodiment, a hinge is provided on one side panel, and the side panel is rotatably connected to the safety door 3 via the hinge, and a door suction structure is provided on the other side panel. Figure 2 As shown, the door stopper structure includes a fixing block 41 connected to the side panel and a magnetic member 42 disposed on the fixing block 41. In this embodiment, the fixing block 41 is L-shaped, one end of the fixing block 41 is fixedly connected to the side panel, and the other end of the fixing block 41 is provided with a threaded hole. The magnetic member 42 is a hexagonal screw-type magnet, and the screw-type magnet is threadedly connected to the fixing block 41. A nut is also connected to the screw-type magnet, and the screw-type magnet is connected to the nut after passing through the fixing block 41.

[0042] Optionally, a door suction block 43 is further provided on the inner side of the safety door 3, and the door suction block 43 is used to cooperate with the magnetic member 42 to keep the safety door 3 in a closed state. A handle is provided on the outer side of the safety door 3 to facilitate the operator to open the safety door 3.

[0043] like Figure 1 and Figure 3 As shown, an electronic lock 51 is further provided in the charging compartment, and a positioning lock hole 53 cooperating with the electronic lock 51 is provided on the inner side of the safety door 3 , and the electronic lock 51 cooperates with the positioning lock hole 53 to lock the safety door 3 .

[0044] In this embodiment, the electronic lock 51 is electrically connected to the positive electrode 21 and the negative electrode 22 of the cable, and is powered by the positive electrode 21 and the negative electrode 22 of the cable. When the positive electrode 21 and the negative electrode 22 of the cable are powered on, the electronic lock 51 immediately responds and powers on, causing its lock tongue 52 to pop out quickly, thereby locking the safety door 3 to prevent any unauthorized opening to avoid the risk of electric shock for the operator.

[0045] In this embodiment, the electronic lock 51 is a magnetic lock.

[0046] Specifically, the charging steps of the present application include the following:

[0047] When the equipment is powered off, the operator opens the safety door 3 made of a transparent acrylic plate, puts the 48V module into the working compartment, and ensures that the pole of the 48V module is correctly connected to the quick-plug pole head 23, and the adapted low-voltage communication line passes through the rear plate 11 and is connected to the 48V module in the working compartment. Specifically, the pole head 23 and the low-voltage communication line are both existing technologies for battery charging, and this application will not repeat them.

[0048] Close the safety door 3.

[0049] When the cable is powered on, the magnetic lock obtains power through the cable, causing the lock tongue 52 to pop out and automatically lock the closed safety door 3 to prevent unauthorized opening of the safety door 3, thereby avoiding the risk of electric shock. At this time, the door lock status can be observed through the transparent acrylic to confirm that the safety door 3 has been locked, ensuring that the operator knows the current status.

[0050] After charging and discharging begins, the multi-contact design and 5-circle dot-type clamping points inside the quick-plug pole head 23 ensure the safe transmission of large currents and the stability of the connection. During the entire charging and discharging process, the safety door 3 remains closed due to the locking effect of the magnetic lock, further ensuring operational safety.

[0051] After the task is completed, the external power supply is disconnected, the magnetic lock loses power, and the operator is allowed to open the safety door 3 and take out the module that has been charged and discharged.

[0052] As an optional implementation, the electronic lock 51 may also be a power-off unlocking type electric bolt lock, so that the lock tongue 52 pops out after power is turned on and retracts after power is turned off.
