[0035] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0036] like Figures 1-11 As shown, the battery cabinet has a door cover sealing structure. The cabinet 1 contains a high-voltage electrical room and lighting.

[0037] The high-voltage electrical room is equipped with a high-voltage electrical room door cover 2 at its opening, and a first door frame 101 is fixed to the opening of the high-voltage electrical room.

[0038] The high-voltage electrical room door cover 2 is provided with a power-off operation port, the power-off operation port is equipped with a maintenance switch door cover 3, and a second door frame 201 is fixed on the power-off operation port; the power-off operation port is aligned with the maintenance switch located in the cabinet 1.

[0039] The maintenance switch includes a plug 14, and the maintenance switch is de-energized when the plug 14 is unplugged.

[0040] An interlocking mechanism 15 is installed on the inner side of the high-voltage electrical room door cover 2. The interlocking mechanism 15 includes a locking part that is slidably installed on the high-voltage electrical room door cover 2 and a fixing plate 1504 fixed on the first door frame 101. One end of the locking part is inserted into a slot 15041 opened on the fixing plate 1504, and the other end of the locking part is attached to one side of the plug 14.

[0041] The maintenance switch cover 3 has a pressing part 16 on its inner side, and the pressing part 16 abuts against the plug 14.

[0042] Sealing gaskets 10 are provided on the inner edge of the high-voltage electrical room door cover 2 and the inner edge of the maintenance switch door cover 3, and door locks 8 are provided on both the high-voltage electrical room door cover 2 and the maintenance switch door cover 3.

[0043] When opening the high-voltage electrical room, first unlock the door lock 8 on the maintenance switch cover 3. After removing the maintenance switch cover 3, unplug the plug 14 to release the obstruction of the locking part. Then move the locking part to disengage it from the slot 15041, release the interlocking mechanism 15 from locking the high-voltage electrical room cover 2, and finally unlock the door lock 8 on the high-voltage electrical room cover 2. Remove the high-voltage electrical room cover 2 to complete the opening of the high-voltage electrical room.

[0044] In the above-mentioned case, if the plug 14 is not unplugged, the locking part is blocked by the plug 14. If the locking part is moved directly, it will be interfered with and cannot be made to leave the slot 15041. Subsequently, the door lock 8 on the high voltage electrical room door cover 2 cannot be unlocked, and the high voltage electrical room door cover 2 cannot be removed, thus making it impossible to open the high voltage electrical room.

[0045] By setting up the aforementioned interlocking mechanism 15, the maintenance switch is de-energized before the high-voltage electrical room is opened, thereby ensuring the safety of the operators.

[0046] The maintenance switch cover 3 is equipped with a clamping part 16, which provides clamping force to the plug 14. When the high-voltage electrical room is not opened and the battery cabinet 1 is operating normally, the plug 14 can be prevented from becoming loose due to vibration or accidental impact to the cabinet 1.

[0047] With the installation of the sealing gasket 10, after the high-voltage electrical room door cover 2 and the maintenance switch door cover 3 are installed, the sealing gasket 10 on both is in contact with the first door frame 101 and the second door frame 201, ensuring the airtightness.

[0048] like Figure 1As shown, the cabinet 1 also includes a low-voltage electrical compartment and a battery compartment. The low-voltage electrical compartment is located to one side of the high-voltage electrical compartment. There are two battery compartments, which are located below the low-voltage electrical compartment and the high-voltage electrical compartment, respectively. The low-voltage electrical compartment door 4 and the battery compartment door 5 are respectively installed on the low-voltage electrical compartment and the battery compartment door 5, and both the low-voltage electrical compartment door 4 and the battery compartment door 5 are equipped with door locks 8. Two first baffles 6 are fixed on the high-voltage electrical compartment door 2, and the two first baffles 6 are respectively attached to the outside of the low-voltage electrical compartment door 4 and the outside of the battery compartment door 5 located below the high-voltage electrical compartment. A second baffle 7 is fixed on the battery compartment door 5 located below the high-voltage electrical compartment, and the second baffle 7 is attached to the outside of the battery compartment door 5 located below the low-voltage electrical compartment.

[0049] With the above design, the high-voltage electrical room cover 2 is in the installed state, and the low-voltage electrical room cover 4 and one battery room cover 5 are blocked by the first baffle 6. The other battery room cover 5 is blocked by the second baffle 7. Without removing the high-voltage electrical room cover 2, the low-voltage electrical room cover 4 and the battery room cover 5 cannot be disassembled, that is, the low-voltage electrical room and the battery room cannot be opened. Before removing the high-voltage electrical room cover 2, the power of the maintenance switch needs to be cut off. In summary, the opening of the high-voltage electrical room cover 2, the low-voltage electrical room cover 4 and the battery room cover 5 without power disconnection is completely avoided, ensuring the safety of the operators.

[0050] In practice, sealing gaskets 10 are provided on the inner edges of both the low-voltage electrical room door cover 4 and the battery room door cover 5. Door frames are fixed at the openings of both the low-voltage electrical room and the battery room. After the low-voltage electrical room door cover 4 and the battery room door cover 5 are installed, the sealing gaskets 10 are attached to the door frames to ensure the sealing of the door cover installation.

[0051] like Figures 1-2 As shown, handles 9 are fixedly installed on the outer sides of the high-voltage electrical room cover 2, the low-voltage electrical room cover 4, and the battery room cover 5. The handles 9 facilitate the installation and removal of the high-voltage electrical room cover 2, the low-voltage electrical room cover 4, and the battery room cover 5.

[0052] like Figure 3 , Figure 4 as well as Figure 9 As shown, a mounting bracket 11 is fixed inside the cabinet 1, and the maintenance switch is mounted on the mounting bracket 11. The mounting bracket 11 provides an installation position for the maintenance switch.

[0053] like Figure 4 , Figure 9 , Figure 10 as well as Figure 11As shown, the maintenance switch also includes a mounting plate 12 fixed on the mounting bracket 11. A socket 13 is fixed on the mounting plate 12. The socket 13 is fixed with two sets of power interfaces 1301 and two sets of signal interfaces 1302. The power interfaces 1301 and signal interfaces 1302 are electrically connected to the power lines and signal lines in the cabinet 1, respectively. The plug 14 is fixed with two connecting wires 1402. Both ends of the two connecting wires 1402 are electrically connected to connectors 1401, and the connectors 1401 are fixed to the plug 14.

[0054] When plug 14 is inserted into socket 13, the two connectors 1401 of one connecting wire 1402 are connected to the two power interfaces 1301, and the two connectors 1401 of the other connecting wire 1402 are connected to the two signal interfaces 1302, thus connecting the power supply. When plug 14 is unplugged from socket 13, the connectors 1401 are disconnected from the power interfaces 1301 and signal interfaces 1302, thus disconnecting the power.

[0055] With the above design, power can be cut off by unplugging plug 14.

[0056] In specific implementation, such as Figure 10 As shown, the socket 13 is a cylindrical structure with a cross-section on one side, and the plug 14 has a slot that fits the socket 13. This shape design serves as a foolproof design, ensuring that after the socket 13 and the plug 14 are plugged in, the connector 1401 is plugged into the power interface 1301 and the signal interface 1302.

[0057] like Figures 4-5 As shown, the locking part includes a movable bar 1502 and a pin 1503; the pin 1503 is fixed to the movable bar 1502, and the movable bar 1502 is in contact with the plug 14; the pin 1503 is connected to a guide part provided on the high-voltage electrical room door cover 2, and the end of the pin 1503 away from the movable bar 1502 is inserted into the slot 15041.

[0058] like Figures 5-7 As shown, the guide part includes a seat 1501 fixed on the high-voltage electrical room door cover 2. A sliding column 15012 is fixed on the seat 1501, and a guide groove 15011 is provided on one side of the seat 1501. The pin 1503 is slidably engaged with the guide groove 15011, and a sliding groove 15031 is provided on the pin 1503. The sliding groove 15031 is slidably connected with the sliding column 15012.

[0059] like Figures 5-7 As shown, a stop 1505 is fixed on the movable strip 1502, and the stop 1505 is in contact with one side of the seat 1501.

[0060] After the plug 14 is unplugged, the obstruction to the movable bar 1502 is removed. Then, the movable bar 1502 is pulled, and the movable bar 1502 drives the pin 1503 to move. The pin 1503 leaves the slot 15041, and the stop 1505 separates from the side wall of the seat 1501. At the same time, the groove wall at one end of the slide 15031 fits with the slide post 15012, thus unlocking the interlocking mechanism 15.

[0061] When locking the interlocking mechanism 15, the movable bar 1502 is pushed, causing the pin 1503 to insert into the slot 15041. Simultaneously, the stop 1505 on the movable bar 1502 engages with the base 1501, completing the locking process. After locking, the plug 14 is reinstalled, blocking the movable bar 1502.

[0062] In the above description, during the movement of the pin 1503, in addition to being guided by the guide groove 15011, the sliding post 15012 slides against the sliding groove 15031, providing a dual guiding function. When the pin 1503 leaves the slot 15041, the sliding post 15012 is blocked by the groove wall at one end of the sliding groove 15031, preventing the locking part from separating from the guide part, and facilitating the determination of whether the unlocking movement is in place. When the groove wall of the sliding groove 15031 is in contact with the sliding post 15012, the locking part cannot move further, i.e., the unlocking movement is in place. When the pin 1503 is inserted into the slot 15041, the stop 1505 is in contact with the seat 1501, facilitating the determination of whether the locking movement is in place. After the stop 1505 is in contact with the seat 1501, the locking part cannot move further, i.e., the locking movement is in place.

[0063] like Figure 11 As shown, the clamping part 16 includes a fixed cylinder 1601 fixed to the inside of the maintenance switch door cover 3, a movable sleeve 1602 slidably sleeved on the fixed cylinder 1601, and a spring 1603 is provided inside the fixed cylinder 1601.

[0064] The two ends of the spring 1603 abut against the inner side of the maintenance switch cover 3 and the inner end face of the movable sleeve 1602, respectively.

[0065] After plug 14 is inserted into socket 13, install maintenance switch cover 3, align maintenance switch cover 3 with power-off operation port, and move maintenance switch cover 3 toward power-off operation port. First, movable sleeve 1602 fits into plug 14. During subsequent movement of maintenance switch cover 3, movable sleeve 1602 is blocked by plug 14 and cannot move. Fixed cylinder 1601 retracts into movable sleeve 1602 and compresses spring 1603, causing clamping part 16 to retract as a whole. After maintenance switch cover 3 is inserted into power-off operation port, lock 8 is locked. Spring 1603 in clamping part 16 provides pressure to fixed cylinder 1601, clamping plug 14 and providing clamping limit for plug 14, thus preventing loosening.

[0066] When the maintenance switch cover 3 is removed, the clamping part 16 separates from the plug 14. The clamping part 16 is extended as a whole by the elastic force of the spring 1603, thus completing the reset.

[0067] This utility model is not limited to the above-described embodiments. Any changes made to its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
