Description

TECHNICAL FIELD

[0001] The application relates to the technical field of ship battery replacement, in particular to a waterproof door linkage mechanism and a battery replacement ship. BACKGROUND

[0002] Currently, electric driving has been widely applied to the field of ships. Generally, a large-capacity power battery box in the form of a container is used to supply power to the ship to meet the energy demand of the ship during driving. There are battery box replacement structures for side replacement on the market, which need to set up an electrical connection structure on the side wall of the cabin or other hull structure of the ship to electrically connect with the battery box to realize power supply. Such a side replacement structure makes the waterproof requirements of the electrical connection structure on the ship and the battery box higher during replacement, and it is also difficult to realize full mechanization and requires the participation of the ship staff in the replacement operation, thereby failing to well perform the replacement operation in bad environments such as rainy days, and the participation of manual replacement makes it difficult to improve the replacement efficiency and fully ensure the safety.

[0003] For example, the Chinese invention patent with the application number "CN202111672849.X" discloses a ship battery replacement method, device, electronic equipment and storage medium; the battery replacement device of the ship is used to replace the battery box on the electric ship, and the battery replacement device of the ship includes: an unlocking module for unlocking the electrical connection mechanism and the protection mechanism of the low-power battery box on the electric ship based on the battery replacement starting instruction; the electrical connection mechanism is in the accommodation space of the protection mechanism; a first transfer module for transferring the successfully unlocked low-power battery box to a designated position; a first locking module for transferring the full-power battery box to the installation position of the electric ship and locking the full-power battery box. The invention adopts a side replacement method, and cannot realize full-automatic docking when the battery box and the electrical connection device of the ship are docked. SUMMARY

[0004] Therefore, the technical problem to be solved by the present application is to overcome the defects in the prior art that the ship battery replacement can only be semi-automated, which leads to difficult improvement of the replacement efficiency and full guarantee of the safety. The purpose of the present application is to provide a waterproof door linkage mechanism and a battery replacement ship, which can realize automatic synchronous opening / closing of the waterproof door, can be fully automated, can perform replacement operation in any weather environment, and can improve the replacement efficiency and safety.

[0005] The present application provides the following technical solutions:

[0006] The present application provides a waterproof door linkage mechanism, comprising:

[0007] A box end waterproof door is slidably mounted on the bottom of the battery box and is used to open or close the box end electrode head of the battery box;

[0008] A ship-end waterproof door is slidably mounted on the upper surface of the ship-end bracket and is used to open or close the ship-end electrode head of the ship-end bracket;

[0009] The linkage assembly includes a protruding piece and a matching piece, one of the protruding piece and the matching piece is arranged on the ship-end waterproof door, and the other is arranged on the box-end waterproof door. The protruding piece and the matching piece can cooperate with each other to enable the ship-end waterproof door and the box-end waterproof door to be opened or closed synchronously.

[0010] In this solution, firstly, the box-end waterproof door is arranged at the bottom of the battery box and the ship-end waterproof door is arranged on the upper surface of the ship-end bracket, so that the battery box and the ship-end bracket are connected up and down, and then during the battery replacement process, since the battery box is always above the ship-end bracket, the box-end electrode head and the ship-end electrode head can be protected by the battery box body, especially in rainy weather, they can avoid the invasion of rain; secondly, through the mutual cooperation of the protruding parts and the mating parts of the linkage assembly, the ship-end waterproof door and the box-end waterproof door can be opened or closed synchronously, so as to avoid the ship-end electrode head or the box-end electrode head being exposed for too long due to the asynchronous opening or closing process of the ship-end waterproof door and the box-end waterproof door, and being disturbed and eroded by dust, rainwater, etc., and resulting in a long battery replacement time and affecting the battery replacement efficiency; and the closed box-end waterproof door and the ship-end waterproof door can further seal the corresponding box-end electrode head and the ship-end electrode head, which can well protect the two electrode heads from rain, dust, moisture and condensation.

[0011] Preferably, the waterproof door linkage mechanism also includes a driving assembly and a connecting plate, the driving assembly is arranged on the lower surface of the ship end bracket, and the connecting plate is connected between the driving assembly and the ship end waterproof door, so that the driving assembly can drive the ship end waterproof door to move through the connecting plate, and then the linkage assembly can drive the box end waterproof door to move with the ship end waterproof door.

[0012] In this solution, the provision of a drive assembly and a connecting plate allows the waterproof door linkage mechanism to be fully automated. Driven by the drive assembly, the ship-end waterproof door and the tank-end waterproof door can be opened and closed synchronously, without human intervention, thereby improving battery replacement efficiency and safety. Furthermore, because the drive assembly is located on the lower surface of the ship-end bracket, the drive assembly and connecting plate ensure that the ship-end waterproof door does not interfere with its sliding during its entire sliding direction, nor does it affect the docking of the ship-end electrode head and the tank-end electrode head.

[0013] Preferably, the waterproof door linkage mechanism also includes a first guide unit and a first sensing element. The first guide unit is arranged on both sides of the ship-end electrode head along the length direction or width direction of the ship-end electrode head. The first guide unit is connected to the ship-end waterproof door to guide the movement of the ship-end waterproof door. The first sensing element is respectively arranged at both ends of the first guide unit along the moving direction of the ship-end waterproof door and corresponds to the open limit position or the closed limit position respectively. The ship-end waterproof door is provided with a first sensor on one side along its moving direction, so that after the first sensor senses the first sensing element, the ship-end waterproof door is controlled to stop moving.

[0014] In this solution, the movement of the ship-end waterproof door is guided by the first guide unit, so that the ship-end waterproof door can slide back and forth along a predetermined route, thereby improving the movement efficiency and reliability of the ship-end waterproof door; through the first sensing elements provided at both ends of the first guide unit, when the first sensor that moves with the ship-end waterproof door senses the first sensing element, it is confirmed that the ship-end waterproof door has moved to the open limit position or the closed limit position, and then the driving component is controlled to stop moving, so that the ship-end waterproof door no longer moves, which can play a safety protection role for the driving component, the ship-end waterproof door and even the entire waterproof door linkage mechanism.

[0015] Preferably, the waterproof door linkage mechanism also includes a second guide unit and a first limit block, the second guide unit corresponds to the first guide unit, the second guide unit is arranged on both sides of the box-end electrode head, the second guide unit is connected to the box-end waterproof door to guide the box-end waterproof door to move along the length direction or width direction of the box-end electrode head, the first limit block is respectively arranged at both ends of the second guide unit along the moving direction of the box-end waterproof door and corresponds to the open position and the closed position respectively, so that after the box-end waterproof door contacts the first limit block, the linkage assembly can no longer drive the ship-end waterproof door or the box-end waterproof door to move.

[0016] In this solution, the movement of the box-end waterproof door is guided by the second guide unit, so that the box-end waterproof door can slide back and forth along a predetermined route to improve the movement efficiency and reliability of the box-end waterproof door; further, the first limit block is provided to limit the open position and the closed position of the two waterproof doors, so that the position of the box-end waterproof door when it is opened or closed synchronously is determined, thereby avoiding the box-end waterproof door not being opened properly when opening and the inability to achieve electrical connection between the box-end electrode head and the ship-end electrode head, and the box-end waterproof door sliding excessively when closing, thereby affecting the protection of the box-end electrode head.

[0017] Preferably, the waterproof door linkage mechanism also includes a limiting component, which includes a second sensor, a floating part and a second sensing part. There are two second sensors, and the two second sensors are arranged at intervals on one side of the ship-end waterproof door along the moving direction of the ship-end waterproof door. The floating part is connected to the ship-end waterproof door and can float between the two second sensors, and the floating part is connected to the connecting plate and can drive the ship-end waterproof door to move under the drive of the driving component; there are two second sensing parts, which correspond to the second sensors and are arranged on the side wall of the floating part respectively. After any one of the second sensors senses the corresponding second sensing part, it controls the driving component to stop driving the ship-end waterproof door to move.

[0018] In this solution, the floating part is installed at the side end of the ship-end waterproof door in a floating connection manner. When the driving component drives the ship-end waterproof door to slide through the connecting plate and the floating part, when one of the second sensors senses the corresponding second sensing part on the same side, the driving component stops moving. This indicates that the ship-end waterproof door has completed the opening or closing action, avoiding the driving component from continuing to drive and causing excessive movement of the ship-end waterproof door and causing damage.

[0019] For example, when the waterproof door linkage mechanism performs the door opening operation of the box-end waterproof door and the ship-end waterproof door, the driving component is shut down after the second sensor detects the corresponding second sensing element signal, and then the docking of the ship-end electrode head and the box-end electrode head can be controlled; before the battery box is separated from the ship-end bracket, the two waterproof doors are clearly closed to the closed position to ensure that the two electrode heads are isolated from the external environment, playing a role in waterproofing, rainproofing and fogproofing.

[0020] Furthermore, on the basis of the first sensor and the first sensing element, the second sensor and the second sensing element are set to achieve double assurance, making the control of the drive component more reliable, improving the safety and reliability of the ship-end waterproof door and the entire waterproof door linkage mechanism, thereby ensuring the safety and reliability of the ship's power replacement process.

[0021] Preferably, two oppositely arranged fixed plates are provided on one side of the ship-end waterproof door, and two second sensors are respectively arranged on the two fixed plates, a connecting rod is passed through the two fixed plates, the floating member is sleeved on the connecting rod, and elastic bodies are provided between the two ends of the floating member and the fixed plate on the corresponding side, so that the driving component can drive the floating member and the ship-end waterproof door to move synchronously in the process of driving the connecting plate to move, and then the linkage component drives the box-end waterproof door to move synchronously until the box-end waterproof door contacts the first limit block of the battery box, and the box-end waterproof door and the ship-end waterproof door no longer move, and the floating member continues to move with the driving component to drive the second sensing member to move toward the second sensor on the corresponding side until it is sensed by the second sensor to control the driving component to stop driving.

[0022] In this solution, the floating part is sleeved on the connecting rod between the two fixed plates along the moving direction of the ship-end waterproof door, and elastic bodies are installed between the two ends of the floating part and the fixed plates. Therefore, under normal conditions, the floating part is centered in the middle position of the connecting rod through the two elastic bodies. During the opening of the ship-end waterproof door, the driving component drives the ship-end waterproof door to open through the connecting plate, the floating part, the elastic body and the fixed plate, and the linkage component synchronously drives the box-end waterproof door to open until it reaches the opened position. Due to the setting of the first limit block, the two waterproof doors no longer move. At this time, the driving component will continue to drive the floating part to move closer to the fixed plate on one side until the second sensor senses the corresponding second sensing element and stops the entire driving component from moving. Only then can the ship-end electrode head of the ship-end bracket be controlled to extend and dock with the box-end electrode head of the battery box to complete the electrical connection. On the contrary, when the box-end electrode head and the ship-end electrode head are disconnected, the driving assembly and the linkage assembly synchronously drive the two waterproof doors to reset and cover the two electrode heads accordingly. After the two waterproof doors reset to the initial closed position, the two waterproof doors no longer move due to the setting of the first limit block. The driving assembly continues to drive the floating part to move closer to the fixed plate on the other side until the corresponding second sensor senses the second sensing part on that side and stops the entire driving assembly from moving, ensuring that the two waterproof doors each seal the two electrode heads at this time.

[0023] Preferably, the driving assembly includes a motor and a screw connected to the motor, the connecting plate includes a horizontal plate and a vertical plate, the horizontal plate is connected to the screw via a screw seat, the screw seat is sleeved on the screw and can move relative to the screw when the motor drives the screw to rotate, thereby driving the connecting plate to move, the first sensor is arranged on the horizontal plate and arranged upward for sensing the first sensing member, the vertical plate extends upward from one end of the horizontal plate, passes through the upper surface of the ship end bracket, and is connected to the side of the floating member away from the ship end waterproof door.

[0024] In the scheme, the driving assembly is used to realize the sliding movement of the ship end waterproof door, and specifically adopts the screw rod transmission mode to drive the movement of the connecting plate. The first sensor is arranged on the horizontal plate of the connecting plate, and the first sensing element is arranged on the lower surface of the ship end support. The first sensing element and the first sensor are used to limit the limit position of the ship end waterproof door, so that the limit displacement safety protection function is achieved. Secondly, since the driving assembly, the first sensor and the first sensing element are all located below the ship end support, the movement of the ship end waterproof door will not be disturbed.

[0025] Preferably, the upper surface of the ship end support is provided with a horizontal groove extending along the moving direction of the ship end waterproof door for the movement of the vertical plate, and the limiting assembly is provided with a protective shell connected with the ship end waterproof door above. The protective shell is provided with first piano cases covering the horizontal groove above at both ends along the moving direction of the ship end waterproof door. The first piano cases at both ends of the protective shell can be expanded and contracted with the movement of the protective shell, so that the protective shell always covers the horizontal groove during the movement of the ship end waterproof door.

[0026] In the scheme, the limiting mechanism in the protective shell is isolated from the external environment by arranging the protective shell, and the horizontal groove is isolated from the external environment by arranging the first piano case, which can isolate and protect the electrical components in the limiting mechanism and the ship end support, and avoid affecting the service life due to damp. At the same time, the first piano case can always cover the horizontal groove during the movement of the driving assembly driving the connecting plate, the ship end waterproof door and the like, so as to avoid the rain, dust and the like falling into the ship end support through the horizontal groove and affecting the function and service life of the ship end support.

[0027] Preferably, the matching piece has two, which are arranged at both ends of the ship end waterproof door along a direction perpendicular to the moving direction of the ship end waterproof door; and the protruding piece has two, which are arranged on the ship end waterproof door corresponding to the matching piece.

[0028] In the scheme, the matching piece and the protruding piece are respectively arranged in pairs, so as to correspond one by one, thereby improving the reliability of the matching of the two, and enabling the ship end waterproof door and the box end waterproof door to move stably and balancedly. Further, the linkage structure of the matching piece and the protruding piece is simple in structure, reliable in driving, and the matching piece and the protruding piece can be integrally arranged on the box end waterproof door and the ship end waterproof door, or can be fixed on the corresponding box end waterproof door and ship end waterproof door by bolts, which is convenient for replacement and maintenance.

[0029] Preferably, the end of the protruding piece away from the ship end waterproof door is tapered or has an inclined surface, and the cross-sectional area of the protruding piece gradually increases from the end away from the ship end waterproof door to the end close to the ship end waterproof door, so as to guide the protruding piece to enter the matching piece to realize the matching.

[0030] The protruding piece is provided with a conical or inclined surface structure, so as to guide the cooperation of the protruding piece and the matching piece to realize linkage.

[0066] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0067] Additionally, in the following description, specific details are provided to provide a thorough understanding of the examples, however, one skilled in the art will appreciate that the examples can be practiced without these specific details.

[0068] Combine Figures 1-3 As shown, the present application provides a waterproof door linkage mechanism, comprising: a box-end waterproof door 1, a ship-end waterproof door 3 and a linkage assembly 6; wherein, the box-end waterproof door 1 can be slidably mounted on the bottom of the battery box 2, for opening or closing the box-end electrode head 205 of the battery box 2; the ship-end waterproof door 3 can be slidably mounted on the upper surface of the ship-end bracket 4, for opening or closing the ship-end electrode head 401 of the ship-end bracket 4; the linkage assembly 6 includes a protruding piece 601 and a mating piece 602, one of the protruding piece 601 and the mating piece 602 is arranged on the ship-end waterproof door 3, and the other is arranged on the box-end waterproof door 1, and the protruding piece 601 and the mating piece 602 can cooperate with each other to enable the ship-end waterproof door 3 and the box-end waterproof door 1 to be opened or closed synchronously.

[0069] like Figure 1 As shown, after the battery box 2 is completely docked and placed on the ship-end bracket 4, the two waterproof doors are opened synchronously through the linkage component 6 of the waterproof door linkage mechanism. At this time, the ship-end electrode head 401 can be controlled to move upward to achieve docking and battery exchange with the box-end electrode head 205.

[0070] In one example, Figure 3 and Figure 14 As shown, the box end waterproof door 1 is approximately C-shaped as a whole.

[0071] The difference between the embodiments of this specification and the prior art is that Figure 12As shown, the box-end waterproof door 1 is movably arranged at the bottom of the battery box 2, and the battery box 2 is docked at the bottom for battery replacement. The battery box 2 and the ship-end bracket 4 are docked up and down. Therefore, during the battery replacement process, since the battery box 2 is always above the ship-end bracket 4, the box-end electrode head 205 and the ship-end electrode head 401 can be protected by the battery box 2 body, especially in rainy weather. In addition, the waterproof door linkage mechanism realizes the synchronous opening or closing of the ship-end waterproof door 3 and the box-end waterproof door 1, thereby preventing the ship-end electrode head or the box-end electrode head from being exposed for too long due to interference and erosion by dust, rainwater, etc. due to the asynchronous opening or closing process of the ship-end waterproof door and the box-end waterproof door, and causing a long battery replacement time to affect the battery replacement efficiency. The ship-end waterproof door 3 is sealed on the ship-end electrode head 401, and the box-end waterproof door 1 is sealed on the box-end electrode head 205, thereby protecting the two electrode heads from rain, dust, moisture, and condensation.

[0072] It should be pointed out that the protruding piece 601 can be configured on the ship-end waterproof door 3 (in this case, the matching piece 602 is correspondingly set on the box-end waterproof door 1), and the protruding piece 601 can also be configured on the box-end waterproof door 1 (in this case, the matching piece 602 is correspondingly set on the ship-end waterproof door 3), as long as the synchronous opening or closing of the ship-end waterproof door 3 and the box-end waterproof door 1 is ultimately achieved.

[0073] In one example, Figure 3 、 Figure 4 and Figure 13 As shown, the protruding piece 601 is arranged on the ship end waterproof door 3, and the matching piece 602 is correspondingly arranged on the box end waterproof door 1.

[0074] In the embodiments of this specification, Figure 1 As shown, the vertical docking direction of the battery box 2 and the ship end bracket 4 is the Z axis direction, the sliding direction of the box end waterproof door 1 and the ship end waterproof door 3 is the X axis direction, and the horizontal direction perpendicular to the X axis is the Y axis direction.

[0075] In some embodiments, as Figure 4 、 Figure 5 and Figure 11 As shown, the waterproof door linkage mechanism also includes a drive assembly 5 and a connecting plate 501. The drive assembly 5 is arranged on the lower surface of the ship-end bracket 4, and the connecting plate 501 is connected between the drive assembly 5 and the ship-end waterproof door 3, so that the drive assembly 5 can drive the ship-end waterproof door 3 to move through the connecting plate 501, and then the linkage assembly 6 can drive the box-end waterproof door 1 to move with the ship-end waterproof door 3. Driven by the drive assembly 5, the ship-end waterproof door 3 and the box-end waterproof door 1 can be opened and closed synchronously, and the entire process requires no human intervention, thereby improving the efficiency and safety of battery replacement. Figure 4 and Figure 5The driving assembly 5 is arranged on the lower surface of the ship end bracket 4, so that during the entire sliding process of the ship end waterproof door 3 along the sliding direction (X-axis direction), it is ensured that its driving assembly 5 and the connecting plate 501 will not interfere with the sliding of the ship end waterproof door 3, and will not affect the docking of the ship end electrode head 401 and the box end electrode head 205.

[0076] like Figure 5 and Figure 11 As shown, the drive assembly 5 includes a motor 507, which transmits power to the connecting plate 501 through a transmission mechanism. The transmission mechanism can be a gear rack transmission structure, a pulley transmission structure, or a screw rod and screw seat transmission structure, the purpose of which is to achieve linear movement of the connecting plate 501.

[0077] In one example, Figure 5 and Figure 11 As shown, the drive assembly 5 also includes a screw rod 510 connected to the motor 507, and the connecting plate 501 includes a horizontal plate 5011 and a vertical plate 5012. The horizontal plate 5011 is connected to the screw rod 510 through a screw rod seat 509. The screw rod seat 509 is sleeved on the screw rod 510 and can move relative to the screw rod 510 when the motor 507 drives the screw rod 510 to rotate, thereby driving the connecting plate 501 to move.

[0078] like Figure 5 As shown, the ship end bracket 4 includes a bracket plate 405, and the driving assembly 5 is arranged on the lower surface of the bracket plate 405. The upper surface of the bracket plate 405 of the ship end bracket 4 is provided with a horizontal groove 406 extending along the moving direction of the ship end waterproof door 3 for the vertical plate 5012 to move along it. The vertical plate 5012 is a thin-walled plate structure, and the horizontal groove 406 serves to avoid the vertical plate 5012.

[0079] Of course, in other embodiments, the motor 507 can also realize the movement of the connecting plate 501 through other transmission structures, such as a gear rack transmission structure.

[0080] In some embodiments, as Figure 6As shown, the waterproof door linkage mechanism also includes a first guide unit 307 and a first sensing element. The first guide unit 307 is provided on both sides of the ship-end electrode head 401 along the length direction or width direction of the ship-end electrode head 401. The first guide unit 307 is connected to the ship-end waterproof door 3 to guide the movement of the ship-end waterproof door 3. The first guide unit 307 enables the ship-end waterproof door 3 to slide back and forth along a predetermined route to improve the movement efficiency and reliability of the ship-end waterproof door 3; the first sensing element is provided at both ends of the first guide unit 307 along the movement direction of the ship-end waterproof door 3 and corresponds to the open limit position or the closed limit position respectively (the first sensing element does not produce relative displacement). A first sensor 508 is provided on one side of the ship-end waterproof door 3 along its movement direction, so that after the first sensor 508 senses the first sensing element, the ship-end waterproof door 3 stops moving. The first sensing element and the first sensor 508 are used to limit the limit position of the ship-end waterproof door 3, so that it has a limit displacement safety protection function.

[0081] In the above embodiment, the entire waterproof door linkage mechanism can control the closing and shutting of the drive assembly 5 by sensing the first sensing element via the first sensor 508. In this embodiment, the first sensing element corresponds to the door open limit position or the door closed limit position. Of course, if the entire waterproof door linkage mechanism is not equipped with a second sensor, it can control the closing and shutting of the drive assembly 5 via the first sensing element and the first sensor 508.

[0082] like Figure 5 As shown, in one example, the first sensing component specifically includes a door opening limit position bracket 402 and a door closing limit position bracket 403, both of which are arranged on the lower surface of the ship end bracket 4 and will not interfere with the movement of the ship end waterproof door 3; the door opening limit position bracket 402 is arranged on the side away from the ship end electrode head 401, and the door closing limit position bracket 403 is correspondingly arranged on the side close to the ship end electrode head 401.

[0083] Among them, such as Figure 6 and Figure 11 As shown, the first sensor 508 is arranged on the horizontal plate 5011 and is arranged upward to sense the first sensing member, and the vertical plate 5012 extends upward from one end of the horizontal plate 5011 through the upper surface of the ship-end bracket 4 and is connected to one side of the ship-end waterproof door 3; during the entire sliding process of the ship-end waterproof door 3 along the sliding direction, it is ensured that its driving component 5 and the connecting plate 501 will not interfere with the sliding of the ship-end waterproof door 3, and will not affect the docking of the ship-end electrode head 401 and the box-end electrode head 205.

[0084] It should be pointed out that the configuration of the first guide unit 307 is not limited, as long as it can guide the sliding of the ship-end waterproof door 3. It can be a slide rail slider structure or other structures such as an optical axis guide.

[0085] In one example, Figure 6As shown, the first guide unit 307 is specifically a linear slide rail installed on the bracket plate 405 of the ship end bracket 4, and the ship end waterproof door 3 is slidably installed on the ship end waterproof door 3; Figure 2 As shown, the first guide units 307 are arranged on both sides of the ship end electrode head 401 along the Y-axis direction, and the first guide units 307 are parallel to the length direction of the ship end electrode head 401.

[0086] In some preferred embodiments, Figures 7-10 As shown, the waterproof door linkage mechanism also includes a limit assembly, which includes a second sensor, a floating member 502 and a second sensing member. There are two second sensors, which are arranged at intervals on one side of the ship-end waterproof door 3 along the moving direction of the ship-end waterproof door 3. The floating member 502 is connected to the ship-end waterproof door 3 and can float between the two second sensors. The floating member 502 is connected to the connecting plate 501 and can drive the ship-end waterproof door 3 to move under the drive of the driving assembly 5. There are two second sensing members, which are respectively arranged on the side wall of the floating member 502 corresponding to the second sensors. After any second sensor senses the corresponding second sensing member, it controls the driving assembly 5 to stop driving the ship-end waterproof door 3 to move. The floating member 502 is installed at the side end of the ship-end waterproof door 401 in a floating connection manner. When the driving component 5 drives the ship-end waterproof door 401 to slide through the connecting plate 501 and the floating member 502, when one of the second sensors senses the corresponding second sensing member on the same side, the driving component 5 stops moving, which indicates that the ship-end waterproof door 401 has completed the opening or closing action, thereby avoiding the driving component 5 continuing to drive and causing excessive movement of the ship-end waterproof door 401 and damage.

[0087] In this embodiment, on the basis of the first sensor and the first sensing element, the second sensor and the second sensing element are provided to achieve double assurance, so that the control of the drive component 5 is more reliable, and the safety and reliability of the entire waterproof door linkage mechanism are improved, thereby ensuring the safety and reliability of the ship's power replacement process.

[0088] It should be noted that in this embodiment, the drive assembly 5 is shut down by sensing signals from the two second sensors, ensuring that the two waterproof doors have fully entered the open position or the closed position, and thereby performing subsequent operations such as electrode head docking (in this embodiment, if the second sensor does not receive a corresponding signal, the subsequent electrode head docking operations are not performed). At this time, the first sensor 508 will not sense the first sensing element signal during normal operation (the first sensor 508 and the first sensing element are used for displacement limit protection, and the first sensing element corresponds to the open limit position and the closed limit position of the ship-end waterproof door 3). During the opening or closing operation of the two waterproof doors, only when the drive assembly 5 fails to shut down normally due to situations such as failure of the second sensor, or when the protruding member 601 and the mating member 602 do not cooperate correctly and fail to achieve linkage, the first sensor 508 is required to detect the first sensing element and control the entire drive assembly 5 to shut down. Therefore, the first sensor 508 can be used for extreme position protection and can serve as the first safety protection for the motor 507. In addition, torque threshold protection can be set on the motor 507 to serve as the second safety protection for the motor 507.

[0089] In some embodiments, when the first sensor detects that the first sensing element indicates that the second sensor has failed, an alarm signal can be output simultaneously to inspect and repair the entire waterproof door linkage mechanism.

[0090] like Figure 7 and Figure 8 As shown, the second sensor specifically includes a door opening limit sensor 303 and a door closing limit sensor 304, and the floating member 502 is floatingly installed between the door opening limit sensor 303 and the door closing limit sensor 304; Figure 6 、 Figure 7 and Figure 11 As shown, the second sensing element is fixed on the side wall of the floating element 502, and specifically includes a door opening detection bracket 505 and a door closing detection bracket 506; the door opening detection bracket 505 is arranged on the side corresponding to the door opening limit sensor 303, and the door closing detection bracket 506 is arranged on the side corresponding to the door closing limit sensor 304.

[0091] When the second sensor detects the signal of the opening detection bracket 505, the driving assembly 5 stops driving the ship end waterproof door 3 to move, which indicates that the ship end waterproof door 3 has been determined to be in the open position. Only when the second sensor receives the corresponding signal, the subsequent electrical connector docking operation can be performed. Similarly, when the closing limit sensor 304 detects the signal of the closing detection bracket 506, the driving assembly 5 stops driving the ship end waterproof door 3 to move, which indicates that the ship end waterproof door 3 has been determined to be in the closed position. At this time, the system can control the battery box 2 to separate upward from the ship end bracket 4 (to ensure that the box end waterproof door 1 is sealed and closed on the box end electrode head 205). When the waterproof door linkage mechanism performs the opening operation of the box end waterproof door 1 and the ship end waterproof door 3, the driving assembly 5 stops after the second sensor detects the corresponding second sensing element signal, and then the docking of the ship end electrode head 401 and the box end electrode head 205 can be controlled. Before the battery box 2 separates from the ship end bracket 4, the two waterproof doors are clearly closed to the closed position, which ensures that the two electrode heads are isolated from the external environment, and plays a role in waterproof, rainproof and fog-proof.

[0092] In an example, as shown in Figure 6 and Figure 11 , the opening detection bracket 505 and the closing detection bracket 506 of the second sensing element are fixed on the side wall of the floating element 502 through the vertical plate 5012.

[0093] In some embodiments, as shown in Figure 11 , the vertical plate 5012 of the connecting plate 501 is provided with a cable slot 511 on both sides, which is used to install and position the cables of the opening limit sensor 303 and the closing limit sensor 304 of the second sensor.

[0094] In some embodiments, as shown in Figure 8 , the ship end waterproof door 3 is provided with two fixed plates arranged oppositely on one side, and two second sensors are arranged on the two fixed plates respectively, as shown in Figure 8 , the fixed plate specifically includes a first fixed plate 301 and a second fixed plate 302, the first fixed plate 301 is used to install the opening limit sensor 303 of the second sensor, and the second fixed plate 302 is used to install the closing limit sensor 304 of the second sensor; as shown in Figures 8-10As shown, a connecting rod 305 is passed through the two fixed plates, and a floating member 502 is sleeved on the connecting rod 305. An elastic body is provided between the two ends of the floating member 502 and the fixed plate on the corresponding side, so that the driving component 5 can drive the floating member 502 and the ship-end waterproof door 3 to move synchronously in the process of driving the connecting plate 501 to move, and then the linkage component 6 drives the box-end waterproof door 1 to move synchronously, until the box-end waterproof door 1 contacts the first limit block at the bottom of the battery box 2, and the box-end waterproof door 1 and the ship-end waterproof door 3 no longer move (that is, the box-end waterproof door 1 and the ship-end waterproof door 3 have reached the designated open position or closed position), and the floating member 502 continues to move with the driving component 5 (overcoming the elastic force of the corresponding elastic body) and drives the second sensing member to move toward the second sensor on the corresponding side until it is sensed by the second sensor to control the driving component 5 to stop driving. When the two waterproof doors are opened, after the box-end waterproof door 1 and the ship-end waterproof door 3 reach the designated open position, the second sensor will shut down the drive component 5 only after sensing the corresponding second sensing element signal, indicating that the two waterproof doors have been determined to enter the open position. Only then can the entire system perform the subsequent docking operation of the two electrode heads, ensuring that the two waterproof doors will not collide with the two electrode heads during the docking process.

[0095] It should be noted that before the elastic body is compressed to cause relative displacement of the floating member 502, the box-end waterproof door 1 and the ship-end waterproof door 3 have already abutted against the first limit block and have reached the open position or the closed position.

[0096] like Figure 9 and Figure 10 As shown, the elastic body specifically includes a first elastic body 503 and a second elastic body 504 of identical structure. In this embodiment, the first elastic body 503 and the second elastic body 504 have the same elastic force. The first elastic body 503 is installed between the first fixing plate 301 and the floating member 502, and the second elastic body 504 is installed between the second fixing plate 302 and the floating member 502. The connecting rod 305 is fixed between the first fixing plate 301 and the second fixing plate 302 by a washer and a nut.

[0097] like Figure 10As shown, at this time, the floating member 502 is in the middle position of the connecting rod 305 (basically in the center state during operation, and only after the two waterproof doors abut against the first limit block will the driving component 5 drive the floating member 502 to cause relative displacement). In the process of the ship-end waterproof door 3 synchronously driving the box-end waterproof door 1 to open, the driving component 5 drives the ship-end waterproof door 3 to open through the connecting plate 501, the floating member 502, the elastic body and the fixed plate, and synchronously drives the box-end waterproof door 1 to open through the linkage component 6 until it reaches the open position. The setting of the position block prevents the two waterproof doors from moving. At this time, the driving assembly 5 will continue to drive the floating part 502 to move closer to the first fixed plate 301 (overcoming the elastic force of the first elastic body 503 to compress it) until the door opening limit sensor 303 of the second sensor senses the door opening detection bracket 505 of the second sensor to stop the movement of the entire driving assembly 5, indicating that the two waterproof doors have been fully opened. At this time, the system can control the ship end electrode head 401 of the ship end bracket 4 to extend and dock with the box end electrode head 205 of the battery box 2 to complete the electrical connection.

[0098] On the contrary, when the box-end electrode head 205 is disengaged from the ship-end electrode head 401, the driving assembly 5 and the linkage assembly 6 synchronously drive the two waterproof doors to reset and cover the two electrode heads accordingly. After the two waterproof doors are reset to the initial closed position, the two waterproof doors no longer move due to the setting of the first limit block. The driving assembly 5 continues to drive the floating part 502 to move closer to the second fixed plate 302 on the other side (overcoming the elastic force of the second elastic body 504 to compress it) until the corresponding second sensor's door closing limit sensor 304 senses the door closing detection bracket 506 of the second sensing part on this side and stops the entire driving assembly 5 from moving, indicating that the two waterproof doors have been completely sealed and covered on the corresponding electrode heads. Only then can the entire battery box 2 be disengaged from the ship-end bracket 4 (make sure that the box-end waterproof door 1 at the bottom of the battery box 2 after disengagement is a sealed cover covering the box-end electrode head 205).

[0099] In some embodiments, as Figure 4As shown, a protective shell 308 connected to the ship-end waterproof door 3 is provided above the limit assembly. The protective shell 308 isolates the limit mechanism within the protective shell 308 from the external environment. A first accordion cover 309 covering the horizontal slot 406 is provided at both ends of the protective shell 308 along the movement direction of the ship-end waterproof door 3. The first accordion covers 309 at both ends of the protective shell 308 can be extended and retracted as the protective shell 308 moves, ensuring that the protective shell 308 always covers the horizontal slot 406 during movement with the ship-end waterproof door 3. The first accordion covers 309 can be used to protect against dust and rain. By isolating the limit mechanism from the external environment with the protective shell 308 and the horizontal slot 406 from the external environment with the first accordion cover 309, the limit mechanism and the electrical components within the ship-end bracket 4 can be isolated and protected, preventing problems such as moisture and rust that could affect their service life. At the same time, the first accordion cover 309 can always cover the horizontal groove 406 without affecting the movement of the driving component 5 driving the connecting plate 501, the ship end waterproof door 3, etc., to prevent rainwater, dust, etc. from falling into the ship end bracket 4 through the horizontal groove 406 and affecting the function and service life of the ship end bracket 4.

[0100] In some embodiments, as Figure 3 and Figure 13 As shown, there are two mating members 602, which are arranged at both ends of the tank-end watertight door 1 in a direction perpendicular to the movement direction of the tank-end watertight door 1. There are two protruding members 601, and corresponding mating members 602 are arranged on the ship-end watertight door 3. The mating members 602 and the protruding members 601 are matched one by one, thereby improving the reliability of the two fittings, ensuring that the forces on both sides of the ship-end watertight door 3 and the tank-end watertight door 1 are balanced and move smoothly.

[0101] In one example, Figure 3 and Figure 13 As shown, the fitting 602 includes two door opening flanges 603 and door closing flanges 604 extending along the Y axis, with an open slot formed between the two flanges; Figure 7 As shown, the protruding piece 601 is provided on the ship end waterproof door 3, and the protruding piece 601 extends into the opening groove of the matching piece 602 to realize linkage cooperation, which is used to synchronously drive the movement of the ship end waterproof door 3 and the box end waterproof door 1.

[0102] The mating member 602 and the extending member 601 can be integrally mounted on the tank-end watertight door 205 and the vessel-end watertight door 401, or they can be bolted to the corresponding tank-end watertight door 205 and vessel-end watertight door 401, facilitating replacement and maintenance. In one example, both the mating member 602 and the extending member 601 are bolted to the corresponding tank-end watertight door 1 and vessel-end watertight door 3, also facilitating assembly and disassembly. In other embodiments, the mating member 602 can also be configured as a hole, as long as it allows for easy insertion and mating of the extending member 601.

[0103] In some embodiments, as Figure 4 As shown, the end of the protruding piece 601 away from the ship-end waterproof door 3 is set to be conical or have an inclined surface, and its cross-sectional area gradually increases from the end away from the ship-end waterproof door 3 to the end close to the ship-end waterproof door 3 to guide the protruding piece 601 to extend into the matching piece 602 to achieve matching, so as to facilitate guiding the protruding piece 601 to match with the matching piece 602 to achieve linkage.

[0104] In some embodiments, as Figure 13 As shown, the waterproof door linkage mechanism also includes a second guide unit 204 and a first limit block. The second guide unit 204 corresponds to the first guide unit 307. The second guide unit 204 is arranged on both sides of the box-end electrode head 205. The second guide unit 204 is connected to the box-end waterproof door 1 to guide the box-end waterproof door 1 to move along the length direction or width direction of the box-end electrode head 205. The first limit block is respectively arranged at both ends of the second guide unit 204 along the moving direction of the box-end waterproof door 1 and corresponds to the open position and the closed position respectively. Therefore, after the box-end waterproof door 1 contacts the first limit block, the linkage assembly 6 can no longer drive the ship-end waterproof door 3 or the box-end waterproof door 1 to move. This embodiment is equipped with a first limit block to limit the open position and closed position of the two waterproof doors, so that the position of the box-end waterproof door 1 when it is synchronously opened or closed is determined, thereby avoiding the box-end waterproof door 1 not being opened properly when opened and failing to achieve electrical connection between the box-end electrode head 205 and the ship-end electrode head 401, and avoiding the box-end waterproof door 1 from sliding excessively when closed, thereby affecting the protection of the box-end electrode head 205.

[0105] It should be pointed out that the second guide unit 204 is used to guide the movement of the box-end waterproof door 1, so that the box-end waterproof door 1 can slide back and forth along a predetermined route to improve the movement efficiency and reliability of the box-end waterproof door 1; the setting method of the second guide unit 204 is not limited, as long as it can guide the sliding of the box-end waterproof door 1, it can be a slide rail slider structure or other structures such as an optical axis guide.

[0106] In one example, Figure 13As shown, the second guide unit 204 is a slide rail structure, which is installed on the box support plate 203 at the bottom of the battery box 2 and is used to guide the box-end waterproof door 1 to move along the length of the box-end electrode head 205. The first limit block specifically includes a door opening limit block 201 and a door closing limit block 202, which are used to define the open and closed positions of the two waterproof doors (after the box-end waterproof door 1 touches the first limit block, the drive assembly 5 is in an unclosed state and continues to drive the ship-end waterproof door 3. At this time, the ship-end waterproof door 3 does not move, and the floating member 502 produces relative displacement. The drive assembly 5 can only be shut down after the corresponding signal is detected by the second sensor, indicating that the two waterproof doors have been confirmed to be stopped in the open position or the closed position. Only then can the entire system proceed with subsequent operations such as electrode head docking or complete separation of the battery box 2 from the ship-end support 4). The position of the box-end waterproof door 1 when synchronously opened or closed is fixed, and the two electrode heads will not collide with the two waterproof doors when docking, making it safe and reliable to use.

[0107] In some embodiments, as Figure 7 As shown, the ship end waterproof door 3 is provided with a second folded edge 306 at at least one end along its moving direction. The second folded edge 306 extends upward from the edge of the ship end waterproof door 3, so that the ship end waterproof door 3 avoids interference with the ship end electrode head 401 and its surrounding structures during movement, thereby preventing the life of the ship end electrode head 401 from being affected. Figure 2 、 Figure 4 、 Figure 6 and Figure 16 As shown, the ship end bracket 4 is equipped with a sealing ring 404 above the ship end electrode head 401. The sealing ring 404 has a certain elastic deformation capability. Figure 16 The sealing ring 404 is fixed to the bracket plate 405 of the ship end bracket 4 through the connecting seat 407. The sealing ring 404 includes an annular O-ring 408 and an open sealing ring 409 arranged on the annular O-ring 408. The annular O-ring 408 and the sealing ring 409 have elastic deformation capabilities.

[0108] In a preferred embodiment, the height of the sealing ring 409 in the Z-axis direction is not lower than the height of the lower end surface of the ship-end waterproof door 3, so that when the ship-end waterproof door 3 is closed, the lower end surface of the ship-end waterproof door 3 can form a good contact seal with the sealing ring 404, ensuring that the ship-end electrode head 401 can be sealed and isolated from the external environment.

[0109] In some preferred embodiments, Figure 4 and Figure 6As shown, a second mounting plate 310 is provided at each end of the first guide unit 307. A second accordion cover 311 is provided between the edges of the ship-end watertight door 3 along its movement direction and the corresponding second mounting plate 310, covering the first guide unit 307. The second accordion covers 311 at each end of the ship-end watertight door 3 can extend and retract with the movement of the ship-end watertight door 3, thereby always covering the second guide unit 204 during the movement of the ship-end watertight door 3. In this embodiment, by installing the second accordion covers 311 between the two second mounting plates 310, the entire first guide unit 307 (slide rail) is covered and isolated from the external environment. This protects the first guide unit 307 from moisture, preventing rust and other problems, thereby increasing the service life of the first guide unit 307.

[0110] In some embodiments, as Figure 13 and Figure 14 As shown, the box-end waterproof door 1 is provided with a first folded edge 103 at at least one end along its moving direction. The first folded edge 103 extends downward from the edge of the box-end waterproof door 1, so that the box-end waterproof door 1 avoids interference with the box-end electrode head 205 and its surrounding structures during movement, thereby affecting the life of the box-end electrode head 205.

[0111] In a preferred embodiment, a seal having the same structural principle as the sealing ring 404 is installed on the periphery of the box-end electrode head 205, and the lower end surface of the seal is not higher than the upper end surface of the box-end waterproof door 1 in the Z-axis direction, ensuring that when the box-end waterproof door 1 is closed, its seal can be sealed against the box-end waterproof door 1 to form a contact seal, thereby isolating the box-end electrode head 205 from the external environment.

[0112] In some preferred embodiments, Figure 13 As shown, a first mounting plate 206 is provided at one end of the second guide unit 204, and a limiting member 101 is connected between the first mounting plate 206 and the box end waterproof door 1, so that the box end waterproof door 1 remains in a closed state close to the first mounting plate 206 when not driven by the linkage assembly 6.

[0113] like Figure 13 and Figure 15 As shown, the first mounting plate 206 is arranged on one side of the door closing limit block 202, and the limit member 101 is a spring, one end of which is hooked on the first mounting plate 206, and the other end is hooked on the hook hole 102 of the box end waterproof door 1; the limit member 101 always provides a force for the box end waterproof door 1 to move toward the first mounting plate 206, ensuring that the box end waterproof door 1 can always be in a closed state when it is not subjected to the force of the linkage component 6, so that the box end electrode head 205 is always closed when it is not electrically connected to the ship end electrode head 401, thereby protecting the box end electrode head 205.

[0114] Based on the same inventive concept, an embodiment of this specification also provides a battery-exchange ship, comprising a hull, a battery box 2, and a waterproof door linkage mechanism as described in any of the aforementioned embodiments. A ship-end bracket 4 for carrying the battery box 2 is provided on the hull, and a ship-end electrode head 401 is provided in the ship-end bracket 4 facing upward, and a box-end electrode head 205 is provided at the bottom of the battery box 2 facing downward. When the battery-exchange ship is exchanging batteries, the box-end electrode head 205 is electrically disconnected from the ship-end electrode head 401, and the waterproof door linkage mechanism synchronously closes the box-end waterproof door 1 and the ship-end waterproof door 3 to protect the box-end electrode head 205 and the ship-end electrode head 401, so that the battery box 2 can be detached from the ship-end bracket 4; when the battery box 2 is installed on the ship-end bracket 4, the waterproof door linkage mechanism synchronously opens the box-end waterproof door 1 and the ship-end waterproof door 3 so that the box-end electrode head 205 is electrically connected to the ship-end electrode head 401 to provide power for the battery-exchange ship.

[0115] like Figure 1 and Figure 2 As shown, the battery-swapping ship adopts a bottom-swapping mode. The ship-end bracket 4 is provided with a matching cavity 410 that can match the battery box 2. The matching cavity 410 is arranged upward, and the matching cavity 410 is provided with a buffer spring 411 that can contact the battery box 2 to play a buffering role. After the battery box 2 is docked and matched with the ship-end bracket 4, the waterproof door linkage mechanism synchronously opens the box-end waterproof door 1 and the ship-end waterproof door 3, and the ship-end electrode head 401 extends upward and automatically docks with the box-end electrode head 205. The ship-end bracket 4 and the battery box 2 of the battery-swapping ship are in a vertical docking relationship. Therefore, during the battery-swapping process, since the battery box 2 is always above the ship-end bracket 4, the box-end electrode head 205 and the ship-end electrode head 401 can be protected by the battery box 2 body, especially in rainy weather, to avoid the invasion of rainwater. The waterproof door linkage mechanism can realize the synchronous opening or closing of the ship-end waterproof door 3 and the box-end waterproof door 1, thereby avoiding the ship-end electrode head from being damaged due to the asynchronous opening or closing process of the ship-end waterproof door 3 and the box-end waterproof door 1. One of the electrode heads 401 or 205 at the box end is exposed for too long and is interfered with and eroded by dust, rain, etc., resulting in a longer battery exchange time and affecting the battery exchange efficiency; and the closed box end waterproof door 1 and the ship end waterproof door 3 can further seal the corresponding box end electrode head 205 and the ship end electrode head 401, which can well protect the two electrode heads from rain, dust, moisture and condensation. The battery exchange ship can be fully automated and can perform battery exchange operations in any weather environment, thereby improving the battery exchange efficiency and safety.
