[0046] The application will be further described in the following embodiments, but the application is not limited in the scope of the embodiments.

[0047] Embodiment 1

[0048] The embodiment provides an opening and closing detection system of a waterproof door of a battery replacement system. Referring to Figures 1 to 4 , the waterproof door includes a first waterproof door 11 on the battery connection device side and a second waterproof door 21 on the battery side 2. The battery connection device side includes a battery connection device main body 1, and the opening and closing detection system includes an opening detection part, a closing detection part, an opening detection device arranged on the battery connection device main body, and a closing detection device arranged on the battery connection device main body; the opening detection part is arranged on the first waterproof door 11 and / or the second waterproof door 21, so that when the waterproof door where the opening detection part is located is in an open door state, the opening detection device detects the opening detection part, and generates an open door in-place signal; the closing detection part is arranged on the first waterproof door 11 and / or the second waterproof door 21, so that when the waterproof door where the closing detection part is located is in a closed door state, the closing detection device detects the closing detection part, and generates a closed door in-place signal.

[0049] In some optional embodiments, the waterproof door on the battery connection device side is a waterproof door arranged on the battery connection device side of a vehicle. In other optional embodiments, the waterproof door on the battery connection device side is a waterproof door arranged on the battery connection device side of a battery replacement device.

[0050] In some optional embodiments, the first waterproof door 11 and the second waterproof door 21 abut against each other in the opening direction, so that the first waterproof door 11 and the second waterproof door 21 reach the open door state synchronously; the opening detection device is a first detection device; the opening detection part is arranged on the first waterproof door 11 or the second waterproof door 21; and the first detection device detects the opening detection part, thereby generating an open door in-place signal of the first waterproof door and the second waterproof door.

[0051] Specifically referring to Figure 3 , the waterproof door on the battery connection device side is a waterproof door arranged on the battery connection device side of a battery replacement device, and the first waterproof door 11 is provided with an abutting part 111. When the opening operation is performed, the abutting part 111 is slightly higher than the upper edge of the second waterproof door 21, the battery replacement device approaches the battery, so that the first waterproof door 11 and the second waterproof door 21 are close to each other, then the second waterproof door 21 moves upward under the action of external force, the upper edge of the second waterproof door 21 abuts against the abutting part 111 of the first waterproof door 11, thereby driving the first waterproof door 11 to move upward synchronously. Referring to Figure 3A second detection unit 112 is provided on the first waterproof door 11, and a first detection device 121 is provided on the main body of the battery connection device. The first detection device 121 serves as a door opening detection device, and the second detection unit 112 serves as a door opening detection unit. The first detection device 121 is located at the end along the opening direction near the first side of the main body of the battery connection device 1, and the second detection unit 112 is located at the beginning along the opening direction near the first side of the first waterproof door 11. The first side of the first waterproof door 11 corresponds to the first side of the main body of the battery connection device 1 when it is closed. When the first waterproof door 11 is moved upward to the position shown in the figure by the second waterproof door 21, the first detection device 121 detects the second detection unit 112, which indicates that both the first waterproof door 11 and the second waterproof door 21 are fully opened, and the first detection device 121 generates a door opening signal.

[0052] In other alternative embodiments, the door opening detection unit is disposed on the second waterproof door. Since the first and second waterproof doors move to the open state synchronously, the opening state of both waterproof doors can be determined by setting up a single door opening detection unit.

[0053] In some alternative embodiments, corresponding opening detection units and corresponding opening detection devices are respectively provided on the first and second waterproof doors. The opening / closing detection system also includes a position signal receiving device (not shown in the figure). The position signal receiving device receives the opening position signals from all the opening detection devices to determine that the waterproof door is open. That is, only when all the opening detection devices corresponding to the first waterproof door detect the opening detection unit corresponding to the first waterproof door, and all the opening detection devices corresponding to the second waterproof door detect the opening detection unit corresponding to the second waterproof door, does it indicate that both waterproof doors are fully open, and only then can the waterproof door be determined to be open. The position signal receiving device can be implemented using a microcontroller.

[0054] In some alternative implementations, refer to Figure 4 The door closure detection device includes a second detection device 113 and a third detection device 114. The door closure detection unit includes a first detection unit 211 and a second detection unit 112. The second detection unit 112 is disposed on the first waterproof door 11, and the first detection unit 211 is disposed on the second waterproof door 21. When the second detection device 113 detects the first detection unit 211 and the third detection device 114 detects the second detection unit 112, a door closure signal is generated.

[0055] In specific implementation, the first detection device 121 is disposed at the end of the first side of the battery connection device body 1 along the opening direction; the second detection part 112 is disposed at the beginning of the first side of the first waterproof door 11 along the opening direction, and the first side of the first waterproof door 11 corresponds to the first side of the battery connection device body 1 when the door is closed; the second detection device 113 is disposed at the end of the second side of the battery connection device body 1 along the opening direction; the first detection part 211 is disposed at the end of the second side of the second waterproof door 21 along the opening direction, and the second side of the second waterproof door 21 corresponds to the second side of the battery connection device body 1 when the door is closed; and the third detection device 114 is disposed at the beginning of the first side of the battery connection device body 1 along the opening direction.

[0056] During the closing process, the first waterproof door 11 and the second waterproof door 21 move downwards under the action of external forces such as gravity, and there may be a situation where their movements are not synchronized. When the first waterproof door 11 moves to the closed position, the third detection device 114 detects the second detection unit 112, indicating that the first waterproof door 11 is closed. That is, the second detection unit 112 is reused in both opening and closing detection. When the second waterproof door 21 moves to the closed position, the second detection device 113 detects the first detection unit 211, indicating that the second waterproof door 21 is closed. The closing signal receiving device receives the closing signal from all the closing detection devices and determines that the waterproof door is in the closed state.

[0057] In practical implementation, the detection device uses a contact sensor, with the detection part being an iron sheet or block corresponding to the contact sensor; or it uses a Hall sensor, with the detection part being a magnet corresponding to the Hall sensor. The detection device can also be implemented using other relevant distance sensors.

[0058] This embodiment also provides a ship battery swapping system, which includes an opening and closing detection system for the waterproof door of the battery swapping system of this embodiment. The second waterproof door is a container door on the side of the container, and the battery is housed inside the container.

The battery connection device side includes a battery connection device body. (Refer to...) Figure 5 The opening and closing detection method includes:

[0061] Step S1: If all door opening detection devices generate a door opening signal, then the waterproof door is confirmed to be in the open state.

[0062] Step S2: If all door closure detection devices generate a door closure signal, then the waterproof door is confirmed to be in the closed state.

[0063] In some optional embodiments, during the opening process, the first waterproof door and the second waterproof door move synchronously; the door opening detection device is a first detection device; the door opening detection unit is disposed on the first waterproof door or the second waterproof door. Accordingly, step S1 specifically includes:

[0064] Once the first detection device detects the door opening detection unit, it generates a door opening signal to confirm that the waterproof door is in the open state.
