[0002] Ships are a general term for all kinds of vessels. A ship is a means of transportation that can navigate or anchor in waterways for transport or operations, and its technical performance, equipment, and structural type vary according to different usage requirements. Ships require mobile power supplies for maintenance.

[0003] After a period of use, power banks require maintenance of their internal battery modules. Existing power bank protective shells typically consist of an outer shell and two end caps on both sides, connected by multiple bolts and threads. This results in low assembly and disassembly efficiency, significantly reducing work efficiency, and the shells also offer poor waterproof and dustproof performance. Therefore, we have introduced a power bank structure for ship maintenance. Utility Model Content

The fixing frame is fixedly disposed inside the housing at the two mounting frames and is used to connect both ends of the housing to the control panel module and the base plate, respectively.

[0008] A sealing mechanism, located between the fixed frame and the corresponding mounting frame, is used to improve the sealing between the housing and the control panel module and the base plate.

[0009] As a further embodiment of this utility model, the control panel module is provided with a control circuit, which is provided with a BMS management module U1. The charging input control terminal DRVIN of the BMS management module U1 is connected to the control terminal of the switch module Q1. The input terminal of the switch module Q1 is connected to the positive terminal DCIN of the charging power supply, and the output terminal is connected to the positive terminal of the battery module group through a resistor R1. The negative terminal of the battery module group is grounded.

[0010] The two outputs of the switch module Q1 are connected to the input of the switch module Q2. The output of the switch module Q2 is the battery discharge terminal DCOUT. The control terminal of the switch module Q2 is connected to the output control terminal DRVOUT of the BMS management module U1.

[0011] The third output of the switch module Q1 is connected to the voltage detection terminal INI of the BMS management module U1, and the fourth output is grounded through resistors R4 and R3 after passing through the step-down module. The common terminal of resistors R4 and R3 is connected to the reference voltage terminal VREF of the BMS management module U1.

When the power supply needs to be disassembled for repair, the push block is pushed with a finger. The push block compresses the spring, and simultaneously, the push block moves the locking block inward via the connecting rod. Once the locking block is completely outside the locking hole, the base plate and control panel module can be removed from the housing. The base plate allows the battery module to detach from the housing. When reinstallation is required after repair, the mounting frame on one side of the base plate and control panel module is inserted into the housing. One side of the mounting frame abuts against the sealing ring, which improves the sealing effect and provides good sealing performance. The locking block is pushed by the inclined plane on one side of the housing. When the locking block aligns with the locking hole, the spring pushes the push block, and the connecting rod causes the locking block to engage in the locking hole. This design facilitates disassembly and assembly during repair, resulting in high efficiency and excellent sealing performance, providing dust and water resistance.

[0029] 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.

[0030] Please see Figures 1 to 3 This utility model provides a technical solution:

[0031] A mobile power supply structure for ship repair includes a control panel module 1, a housing 3, a base plate 4, and a battery module 5. The battery module 5 is connected to the base plate 4 and consists of a DC power module composed of six 3.6V 10AH lithium batteries and a BMS. This battery module can provide 24V power with a maximum of 20A, which can meet the 24V power supply requirements for emergency repairs in the event of a power outage on the ship. The control panel module 1 and the base plate 4 are respectively located on both sides of the housing 3. The structure also includes:

[0032] The mounting mechanism includes a mounting frame 9, a fixing frame 10, and a locking unit. The two mounting frames 9 are slidably disposed on both sides inside the housing 3, and one side of each mounting frame 9 is integrally connected to the control panel module 1 and the base plate 4. The fixing frame 10 is fixedly disposed inside the housing 3 at the two mounting frames 9, and is used to connect both ends of the housing 3 to the control panel module 1 and the base plate 4 respectively.

[0033] A sealing mechanism is located between the fixed frame 10 and the corresponding mounting frame 9 to improve the sealing between the housing 3 and the control panel module 1 and the base plate 4.

[0034] Reference Figure 2 and Figure 3 The locking unit includes a locking block 11, a connecting rod 8 and a push block 2. The base plate 4 and the control panel module 1 are provided with circular grooves on the upper and lower sides, and the push block 2 is slidably disposed in the circular grooves.

[0035] The mounting frame 9 has rectangular grooves on both the top and bottom sides, the locking block 11 is slidably disposed in the rectangular grooves, and the side wall of the housing 3 has locking holes that cooperate with the locking block 11.

[0036] A connecting hole is provided between the circular groove and the rectangular groove. The connecting rod 8 is located on one side inside the connecting hole, and both ends of the connecting rod 8 are fixedly connected to the locking block 11 and the push block 2, respectively. A spring 7 is fixedly provided at the bottom of the circular groove, and the spring 7 is always in a compressed state.

[0037] Reference Figure 2 and Figure 3 The sealing mechanism includes a sealing ring 6, which is fixedly installed on the side wall of the fixed frame 10 and abuts against the corresponding mounting frame 9.

[0038] Reference Figure 2 and Figure 3 The sealing ring 6 is a high-temperature resistant rubber ring, which improves its high-temperature resistance.

[0039] Reference Figure 3 The locking block 11 has a bevel 12 on one side that mates with the locking hole. The bevel 12 is used to facilitate pushing the locking block 11 from the end of the housing.

[0040] Reference Figure 3The opening of the circular groove is chamfered, which prevents the push block 2 from protruding from the circular groove and reduces accidental activation of the push block 2.

[0041] Reference Figure 4 The control panel module includes a control circuit containing a BMS management module U1. The charging input control terminal DRVIN of the BMS management module U1 is connected to the control terminal of the switch module Q1. The input terminal of the switch module Q1 is connected to the positive terminal DCIN of the charging power supply, and one output terminal is connected to the positive terminal of the battery module group via resistor R1. The negative terminal of the battery module group is grounded. Two output terminals of the switch module Q1 are connected to the input terminal of the switch module Q2, whose output terminal is the battery discharge terminal DCOUT. The control terminal of the switch module Q1 is connected to the output control terminal DRVOUT of the BMS management module U1; the third output terminal of the switch module Q1 is connected to the voltage detection terminal INI of the BMS management module U1, and the fourth output terminal is grounded after passing through a step-down module and resistors R4 and R3. The common terminal of resistors R4 and R3 is connected to the reference voltage terminal VREF of the BMS management module U1; the temperature detection terminal TEMP of the BMS management module U1 is connected to the output terminal of the temperature detection sensor module TC1, and the other end of the temperature detection sensor module TC1 is grounded. Switch modules Q1 and Q2 are MOSFETs.

[0042] During battery charging, the BMS management module U1 sends control signals to its charging input control terminal DRVIN and output control terminal DRVOUT, respectively, causing switch module Q1 to open and switch module Q2 to open, thus charging lithium batteries B1-B6. Similarly, the discharging control is achieved by opening switch module Q1 and opening switch module Q2. During battery charging or discharging, the BMS management module U1 monitors the battery temperature through the temperature detection sensor module TC1. By comparing the battery input or output voltage and current values ​​with a reference voltage, the module monitors the battery operating status. If the set value is exceeded, the battery charging or discharging operation is stopped to ensure battery safety.

[0043] When the power bank needs to be disassembled for repair, push the push block 2 with your finger. Push block 2 compresses the spring 7. At the same time, push block 2 drives the locking block 11 to move inward through the connecting rod 8. When the locking block 11 is completely moved outside the locking hole, the base plate 4 and control panel module 1 can be removed from the housing 3. The base plate 4 can drive the battery module 5 away from the housing 3. When it is time to install after repair, insert the mounting frame 9 on one side of the base plate 4 and control panel module 1 into the housing 3. One side of the mounting frame 9 abuts against the sealing ring 6. The sealing ring 6 improves the sealing effect and has good sealing performance. The locking block 11 is pushed by the inclined surface 12 on one side of the housing 3. When the locking block 11 corresponds to the position of the locking hole, the spring 7 pushes the push block 2 and drives the locking block 11 to be locked into the locking hole through the connecting rod 8. It is easy to disassemble and assemble during repair, with high disassembly and assembly efficiency, and good sealing performance, which can achieve dustproof and waterproof.
