Description

Technical Field

[0001] This invention relates to an unlocking device for a battery swapping device, a charging and swapping station, and a battery-swappable ship. Background Technology

[0002] To promote the strategy of converting oil-to-electricity transportation, the approach has been extended from land transportation to sea transportation. Since inland river ports lack the basic conditions for building charging stations, battery swapping has become the main technical route, with charging stations built about 3 kilometers away from the port, utilizing vehicles for short-distance delivery.

[0003] Currently, the battery end of the container is closed via a locking device on the container's waterproof door, enabling battery swapping operations even in adverse weather conditions without the risk of insulation failure due to exposed electrode heads. The waterproof door can be a lift-type door. When needed, the locking device is first opened manually using an unlocking mechanism, then the lift-type door is manually lifted to expose the water and electricity connection device on the container side. A moving device is then activated to connect the water and electricity connection device on the ship side to that on the container side. However, manually unlocking the locking device on the lift-type door using an unlocking mechanism is prone to problems such as misalignment, unlocking failure, and low battery swapping efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art, which is that manual unlocking operation is easy to cause problems such as difficulty in alignment, unlocking failure and low battery swapping efficiency. The present invention provides an unlocking device for battery swapping equipment, a charging and swapping station and a ship capable of battery swapping.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] An unlocking device for a battery swapping device is provided for unlocking a locking mechanism at the battery end. The unlocking device includes a driving mechanism, an unlocking rod, and a sliding platform with a docking device installed. The unlocking rod is connected to the sliding platform. The driving mechanism is used to drive the sliding platform to move along the docking direction of the docking device, thereby moving the unlocking rod and applying force to the unlocking position of the locking mechanism at the battery end to unlock the locking mechanism.

[0007] In this solution, the above-mentioned structure is adopted. The unlocking rod unlocks the locking mechanism and simultaneously docks the docking device after unlocking, which improves the efficiency of the battery swapping equipment. At the same time, the drive mechanism drives the unlocking rod to move in a predetermined direction, achieving very high unlocking accuracy, effectively avoiding misoperation, and greatly improving safety and stability.

[0008] Preferably, the unlocking device includes an elastic element, the two ends of which abut against the unlocking rod and the sliding platform respectively and are used to apply a force to the unlocking rod along the docking direction of the docking device.

[0009] In this solution, the aforementioned structural form ensures successful docking of the docking device on the sliding platform, greatly improving the safety and stability of the unlocking device. Simultaneously, after unlocking is completed and the door is opened, the unlocking rod disengages from the locking mechanism, and an elastic element returns the unlocking rod to its initial position for easy repositioning during the next unlocking operation.

[0010] Preferably, the sliding platform is provided with a first guide component, and the unlocking rod is disposed on the first guide component and moves on the first guide component, so that the unlocking rod can move along the docking direction of the docking device under the drive of the sliding platform.

[0011] In this solution, the above-mentioned structural form is adopted. The first guide component has a guiding function, which makes the unlocking rod move along the docking direction of the docking device, effectively avoiding the phenomenon of offset and misalignment of the unlocking rod during the movement, and improving the unlocking accuracy of the unlocking device.

[0012] Preferably, the first guide component includes a first support disposed on the sliding platform, the first support having a guide hole, and the unlocking rod being clearance-fitted with the guide hole.

[0013] In this solution, the above-mentioned structural form is adopted. The guide hole of the first support ensures that the unlocking rod moves along the docking direction of the docking device. At the same time, the structure is simple and very convenient to process and manufacture.

[0014] Preferably, the outer peripheral surface of the unlocking lever has an outwardly extending protrusion, and the two ends of the elastic member abut against the protrusion and the sliding platform, respectively.

[0015] In this solution, the above-mentioned structural form is adopted. The protrusion facilitates the elastic element to apply a force along the docking direction of the docking device to the unlocking rod; at the same time, the structure is simple and very convenient to process and manufacture.

[0016] Preferably, the first guide component further includes an abutment support, which is located between the first support and the locking mechanism. The protrusion abuts and is fixed to the abutment support, so that the unlocking rod abuts and is fixed to the first support in the docking direction of the docking device.

[0017] In this solution, the above-mentioned structure is adopted. The unlocking rod is fixed to the first support by the protrusion, so that the unlocking rod will be restricted from moving relative to the sliding platform before unlocking. This ensures that the sliding platform and the unlocking rod move in the predetermined direction, achieving very high unlocking accuracy, effectively avoiding misoperation, and greatly improving safety and stability.

[0018] Preferably, the abutment support is the second support in the first guide component. Both the first support and the second support are provided with guide holes. The unlocking rod is clearance-fitted with the guide holes, and the axial direction of both guide holes is parallel to the docking direction.

[0019] In this solution, the above-mentioned structural form is adopted. The guide holes on the first and second supports ensure that the unlocking rod moves along the docking direction of the docking device. At the same time, the structure is simple and very convenient to process and manufacture.

[0020] Preferably, a bushing is provided between the first support and / or the second support and the unlocking rod.

[0021] In this solution, the above-mentioned structural form is adopted. The bushing plays a protective role, reduces the wear of the unlocking rod during movement, and effectively extends the service life of the unlocking device.

[0022] Preferably, the elastic element is a compression spring, which is sleeved on the unlocking rod.

[0023] In this design, the aforementioned structural form provides the compression spring with high elasticity and good performance, allowing it to easily return to its original shape after external force is removed. Simultaneously, it prevents the compression spring from shifting or misaligning during use, further improving the stability of the unlocking device.

[0024] Preferably, the preload of the elastic element is greater than the pressure required to unlock the locking mechanism, so that after the unlocking rod moves to the point where the locking mechanism is unlocked, the sliding platform continues to move in the docking direction, and the unlocking rod compresses the elastic element.

[0025] In this solution, the above-mentioned structural form is adopted, which ensures that the unlocking rod will apply pressure to the locking mechanism to ensure the unlocking of the locking mechanism, thereby improving the stability of the unlocking device. After the unlocking rod moves to the point where the locking mechanism is unlocked, the sliding platform continues to dock with the battery end in the docking direction. The unlocking rod compresses the elastic element and moves in the opposite direction to the docking direction relative to the sliding platform.

[0026] Preferably, the drive mechanism includes a rotating unit and a lead screw. The rotating unit is connected to the lead screw via a coupling and is used to drive the lead screw to rotate. The lead screw is threadedly connected to the sliding platform.

[0027] In this solution, the above-mentioned structural form is adopted, which enables the sliding platform to move linearly along the docking direction of the docking device with high moving accuracy, so as to achieve precise unlocking of the unlocking device and facilitate operation and control.

[0028] Preferably, the rotating unit includes a motor and a reducer, with the two ends of the reducer connected to the motor and the coupling, respectively.

[0029] In this solution, the above-mentioned structure is adopted, and the motor is used to provide driving force. The reducer further makes the screw drive smoother and the movement accuracy higher, which further improves the unlocking accuracy of the unlocking device.

[0030] Preferably, the docking device is disposed at the top of the sliding platform, and the driving mechanism and the unlocking rod are both disposed at the bottom of the docking device, and the docking device includes at least an electrical connector.

[0031] In this solution, the above-mentioned structural form is adopted, which effectively avoids interference between the drive mechanism and the unlocking rod and the docking device. At the same time, it makes full use of the space below and above the sliding platform, making the structure more compact and the space utilization rate high.

[0032] Preferably, there are two unlocking levers, which are spaced apart on the sliding platform.

[0033] In this solution, the above-mentioned structure is adopted, and the two unlocking rods can simultaneously unlock the two locking mechanisms on the lifting door. Both locking mechanisms must be unlocked at the same time to open the door, thereby effectively preventing people from opening the lifting door and avoiding misoperation, thus improving safety and stability.

[0034] Preferably, the unlocking device further includes a second guide component, and the sliding platform is connected to and moves on the second guide component.

[0035] In this solution, the above-mentioned structural form is adopted. The second guide component has a guiding function, which makes the sliding platform, unlocking rod and docking device move along the docking direction of the docking device. This effectively avoids the sliding platform from shifting or misaligning during movement, improves the unlocking accuracy of the unlocking device, and ensures the precise docking of the docking device.

[0036] Preferably, the second guide component includes a guide rail and a slider, the slider being connected to the sliding platform and moving on the guide rail;

[0037] And / or, the number of the second guide components is two, and the two second guide components are respectively disposed at both ends of the sliding platform.

[0038] In this solution, the aforementioned structural form provides high stability and low resistance during sliding, as well as low energy consumption; the structure is simple and the production cost is low. Furthermore, it further improves the stability of the unlocking device.

[0039] Preferably, the end of the unlocking lever facing the locking mechanism has a guide surface.

[0040] In this solution, the above-mentioned structure is used to guide the unlocking rod into the locking mechanism, so that even if there is a slight positional deviation, the unlocking rod can be stably inserted into the locking mechanism.

[0041] A charging and battery swapping station for quick battery swapping on ships, used to unlock the locking mechanism of the waterproof door at the battery end of the ship, includes an unlocking device for the battery swapping equipment as described above, and the docking device includes a water connection device and / or an electrical connection device.

[0042] In this solution, the above-mentioned structure is adopted. The unlocking rod unlocks the waterproof door at the battery end of the ship and simultaneously enables the water and electricity connection after unlocking, which improves the efficiency of the battery swapping equipment. At the same time, the drive mechanism drives the unlocking rod to move in a predetermined direction, achieving very high unlocking accuracy, effectively avoiding misoperation, and greatly improving safety and stability.

[0043] The unlocking lever applies pressure to the locking mechanism, which is sufficient to ensure the unlocking of the locking mechanism, thus improving the stability of the unlocking device. After the unlocking lever moves to the point where the locking mechanism is unlocked, the sliding platform continues to connect with the battery end in the docking direction for water and / or electrical connection. The unlocking lever compresses the elastic element, so that the unlocking lever remains stationary while the sliding platform continues to move in the docking direction. This allows the water and electricity connection to be established immediately after the ship's battery end is unlocked, ensuring waterproofing and avoiding interference with the water and electricity connection caused by the unlocking lever.

[0044] A battery-swappable vessel for unlocking the locking mechanism of the waterproof door at the battery end of the vessel, comprising an unlocking device for the battery-swappable equipment as described above, wherein the docking device comprises a water connection device and / or an electrical connection device.

[0045] In this solution, the above-mentioned structure is adopted. The unlocking rod unlocks the waterproof door at the battery end of the ship and simultaneously enables the water and electricity connection after unlocking, which improves the efficiency of the battery swapping equipment. At the same time, the drive mechanism drives the unlocking rod to move in a predetermined direction, achieving very high unlocking accuracy, effectively avoiding misoperation, and greatly improving safety and stability.

[0046] The unlocking lever applies sufficient pressure to the locking mechanism to ensure its unlocking, thus improving the stability of the unlocking device. After the unlocking lever moves to the point where the locking mechanism is unlocked, the sliding platform continues to connect to the battery end in the docking direction for water and / or electrical connection. The unlocking lever compresses the elastic element, causing the unlocking lever to remain stationary while the sliding platform continues to move in the docking direction. This allows for water and electrical connection to be established immediately after the ship's battery end is unlocked, ensuring waterproofing and preventing the unlocking lever from interfering with the water and electrical connection.

[0047] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0048] The positive and progressive effects of this invention are as follows:

The driving mechanism drives the sliding platform to move along the docking direction of the docking device and moves the unlocking rod. The unlocking rod unlocks the locking mechanism and also enables the docking of the docking device after unlocking. This improves the efficiency of the battery swapping equipment, and the unlocking accuracy is very high, effectively avoiding misoperation and greatly improving safety and stability.

[0071] Docking device 10 Detailed Implementation

[0072] The present invention will be described more clearly and completely below by way of embodiments and in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0073] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment discloses an unlocking device for a ship's battery swapping equipment. The unlocking device is used to unlock the locking mechanism of the waterproof door at the battery end. The unlocking device includes a drive mechanism 1, an unlocking rod 2, and a sliding platform 3 on which a docking device 10 is installed. The unlocking rod 2 is connected to the sliding platform 3. The drive mechanism 1 is used to drive the sliding platform 3 to move along the docking direction of the docking device 10, thereby moving the unlocking rod 2 and applying force to the unlocking position of the locking mechanism at the battery end to unlock the locking mechanism.

[0074] The drive mechanism 1 drives the sliding platform 3 to move along the docking direction of the docking device 10, and also drives the unlocking rod 2 to move along the docking direction of the docking device 10. This causes the unlocking rod 2 to apply force to the unlocking position of the locking mechanism, thereby pushing the unlocking part of the locking mechanism to the unlocking position to unlock the locking mechanism. The unlocking method is not limited to this; it can also be achieved by obtaining force at the unlocking position for touch unlocking, etc. After the locking mechanism is unlocked, the waterproof door at the battery end, using a container lifting door, can be opened to expose the electrical connection equipment and / or water connection equipment inside the container. The docking device 10 on the sliding platform 3 will move along the docking direction to successfully dock with the electrical connection equipment. By unlocking the locking mechanism simultaneously with the docking of the unlocked docking device 10, the efficiency of the battery swapping equipment is improved. At the same time, the drive mechanism 1 drives the unlocking rod 2 to move in a predetermined direction, achieving very high unlocking accuracy, effectively avoiding misoperation, and greatly improving safety and stability.

[0075] The unlocking device includes an elastic element 4, with its two ends abutting against the unlocking rod 2 and the sliding platform 3 respectively, and applying a force to the unlocking rod 2 along the docking direction of the docking device 10. After the locking mechanism is successfully unlocked, the drive mechanism 1 will continue to drive the sliding platform 3 and the unlocking rod 2. After the unlocking rod 2 abuts to the top, it will be unable to move along the docking direction of the docking device 10. Through the compression deformation of the elastic element 4, the unlocking rod 2 will remain stationary while the sliding platform 3 continues to move, ensuring successful docking of the docking device 10 on the sliding platform 3, greatly improving the safety and stability of the unlocking device. At the same time, after the unlocking is completed and the door is opened, the unlocking rod 2 disengages from the locking mechanism, and the elastic element 4 facilitates the reset of the unlocking rod 2 to its initial position for the next unlocking operation.

[0076] In this mechanism, the pre-pressure of the elastic element 4 is greater than the pressure required to unlock the locking mechanism. This causes the unlocking rod 2 to move until the locking mechanism is unlocked. As the sliding platform 3 continues to move in the docking direction, the unlocking rod 2 compresses the elastic element 4. After reaching the unlocking position of the locking mechanism, the unlocking rod 2 will continue to move. Because the pre-pressure of the elastic element 4 is greater than the pressure required to unlock the locking mechanism, the unlocking rod 2 will apply sufficient pressure to the locking mechanism to ensure unlocking, thus improving the stability of the unlocking device. Furthermore, after the unlocking rod 2 moves until the locking mechanism is unlocked, the sliding platform 3 continues to dock with the battery end in the docking direction. The unlocking rod 2 compresses the elastic element 4, and the unlocking rod 2 moves in the opposite direction to the docking direction relative to the sliding platform 3.

[0077] The docking device 10 is located at the top of the sliding platform 3, while the drive mechanism 1 and the unlocking lever 2 are located at the bottom of the docking device 10. The docking device 10 includes at least an electrical connector. After the unlocking lever 2 unlocks the locking mechanism, the electrical connector will connect to the electrical connection equipment inside the container. Positioning the docking device 10 at the top of the sliding platform 3 and the drive mechanism 1 and unlocking lever 2 at the bottom effectively avoids interference between the drive mechanism 1 and unlocking lever 2 and the docking device 10. Simultaneously, it fully utilizes the space below and above the sliding platform 3, resulting in a more compact structure and higher space utilization.

[0078] There are two unlocking levers 2, which are spaced apart on the sliding platform 3. Two locking mechanisms are installed on the lifting door at the container end, spaced apart. The two unlocking levers 2 can simultaneously unlock both locking mechanisms on the lifting door. Both locking mechanisms must be unlocked simultaneously to open the door, effectively preventing unauthorized opening of the lifting door and avoiding misoperation, thus improving safety and stability.

[0079] The end of the unlocking lever 2 facing the locking mechanism has a guide surface 22. The guide surface 22 is used to guide the unlocking lever 2 into the locking mechanism. When unlocking, the unlocking lever 2 first slides through the guide surface 22 and is inserted into the locking mechanism. This can accommodate small positional deviations between the unlocking lever 2 and the locking mechanism, ensuring that the unlocking lever 2 can stably enter the locking mechanism even with slight positional deviations.

[0080] The sliding platform 3 is equipped with a first guide component, and the unlocking rod 2 is mounted on and moves along the first guide component, so that the unlocking rod 2 can move along the docking direction of the docking device 10 under the drive of the sliding platform 3. The first guide component has a guiding function, which makes the unlocking rod 2 move along the docking direction of the docking device 10, effectively avoiding the phenomenon of offset and misalignment of the unlocking rod 2 during movement, and improving the unlocking accuracy of the unlocking device.

[0081] The first guide component includes a first support 31 disposed on the sliding platform 3. The first support 31 has a guide hole, and the unlocking rod 2 is clearance-fitted with the guide hole. The guide hole of the first support 31 ensures that the unlocking rod 2 moves along the docking direction of the docking device. At the same time, the structure is simple and very convenient to process and manufacture.

[0082] The outer peripheral surface of the unlocking rod 2 has an outwardly extending protrusion 21, and the two ends of the elastic member 4 abut against the protrusion 21 and the sliding platform 3 respectively. The elastic member 4 will exert abutment force on the protrusion 21, and the protrusion 21 facilitates the elastic member 4 to apply a force to the unlocking rod 2 along the docking direction of the docking device 10; at the same time, the structure is simple and very convenient to process and manufacture.

[0083] The first guide component also includes an abutment support, which is located between the first support 31 and the locking mechanism. The protrusion 21 abuts and is fixed to the abutment support, so that the unlocking rod 2 abuts and is fixed to the first support 31 in the docking direction of the docking device.

[0084] The abutment support is the second support 32 in the first guide component. Both the first support 31 and the second support 32 are provided with guide holes. The unlocking rod 2 is clearance-fitted with the guide holes, and the axial direction of both guide holes is parallel to the docking direction. The unlocking rod 2 will pass through the guide holes on the first support 31 and the second support 32 and move within the guide holes. The guide holes on the first support 31 and the second support 32 ensure that the unlocking rod 2 moves along the docking direction of the docking device 10. At the same time, the structure is simple and very convenient to manufacture.

[0085] A bushing is provided between the first support 31 and / or the second support 32 and the unlocking rod 2. The bushing serves a protective function, reducing wear on the unlocking rod 2 during movement and effectively extending the service life of the unlocking device.

[0086] In this embodiment, the first support 31 is located between the second support 32 and the locking mechanism, and the protrusion 21 abuts and is fixed to the first support 31, so that the unlocking rod 2 abuts and is fixed to the first support 31 along the docking direction of the docking device 10. Figure 4 As shown, the locking mechanism is located at the left end of the first support 31. The driving mechanism 1 drives the sliding platform 3 and the unlocking rod 2 to move to the left, so that the unlocking rod 2 applies force to the locking mechanism to unlock it. The elastic member 4 abuts against the protrusion 21 of the unlocking rod 2 and applies a leftward force to the protrusion 21. The unlocking rod 2 is fixed to the first support 31 by the protrusion 21, so that the unlocking rod 2 will be restricted from moving relative to the sliding platform 3 before unlocking. This ensures that the sliding platform 3 and the unlocking rod 2 move in the predetermined direction, achieving very high unlocking accuracy, effectively avoiding misoperation, and greatly improving safety and stability.

[0087] The elastic element 4 is a compression spring, which is sleeved on the unlocking rod 2. The compression spring has high elasticity and good performance, and easily returns to its original shape after the external force is removed. At the same time, the compression spring sleeved on the unlocking rod 2 prevents the compression spring from shifting or misaligning during use, further improving the stability of the unlocking device.

[0088] The drive mechanism 1 includes a rotating unit 11 and a lead screw 12. The rotating unit 11 is connected to the lead screw 12 via a coupling 13 and is used to drive the lead screw 12 to rotate. The lead screw 12 is threadedly connected to the sliding platform 3. The rotating unit 11 and the lead screw 12 are connected via the coupling 13. The rotating unit 11 provides driving force and drives the coupling 13 and the lead screw 12 to rotate, so that the sliding platform 3 can move linearly along the docking direction of the docking device 10. The movement accuracy is high, enabling precise unlocking of the unlocking device and facilitating operation and control.

[0089] The rotating unit 11 includes a motor 111 and a reducer 112, with the two ends of the reducer 112 connected to the motor 111 and the coupling 13, respectively. The motor 111 provides driving force, and the reducer 112 further makes the lead screw 12 transmission smoother and the movement accuracy higher, thereby further improving the unlocking accuracy of the unlocking device.

[0090] The unlocking device also includes a second guide component 5, on which the sliding platform 3 is connected and moves. The second guide component 5 has a guiding function, causing the sliding platform 3, the unlocking rod 2, and the docking device 10 to move along the docking direction of the docking device 10, effectively preventing the sliding platform 3 from shifting or misaligning during movement, improving the unlocking accuracy of the unlocking device, and ensuring the precise docking of the docking device 10.

[0091] The second guide component 5 includes a guide rail 51 and a slider 52. The slider 52 is connected to the sliding platform 3 and moves on the guide rail 51. By moving the slider 52 on the guide rail 51, the sliding platform 3 moves along the docking direction of the docking device 10. The sliding process is stable with low resistance and low energy consumption; at the same time, the structure is simple and the production cost is low.

[0092] There are two second guide components 5, which are respectively located at both ends of the sliding platform 3. The two second guide components 5 enable the sliding platform 3 to move smoothly along the docking direction of the docking device 10, further improving the stability of the unlocking device.

[0093] This embodiment also discloses a charging and battery swapping station for quick battery swapping on ships, which is used to unlock the locking mechanism of the waterproof door at the battery end of the ship. The charging and battery swapping station for quick battery swapping on ships includes the unlocking device of the battery swapping equipment as described above, and the docking device includes a water connection device and / or an electrical connection device.

[0094] The unlocking lever 2 simultaneously unlocks the waterproof gate on the ship's battery side and establishes a water-electric connection, improving the efficiency of the battery swapping equipment. Meanwhile, the drive mechanism 1 moves the unlocking lever 2 in a predetermined direction, achieving very high unlocking precision, effectively preventing misoperation and greatly improving safety and stability. The unlocking lever 2 applies sufficient pressure to the locking mechanism to ensure unlocking, improving the stability of the unlocking device. After the unlocking lever 2 moves to the point where the locking mechanism is unlocked, the sliding platform 3 continues to move in the docking direction to establish a water and / or electrical connection with the battery side. The unlocking lever 2 compresses the elastic element 4, keeping the unlocking lever 2 stationary while the sliding platform 3 continues to move in the docking direction. This ensures that the water-electric connection is established immediately after the ship's battery side is unlocked, guaranteeing waterproofing and preventing the unlocking lever 2 from interfering with the water-electric connection.

[0095] This embodiment also discloses a battery-swappable vessel for unlocking the locking mechanism of the waterproof door at the battery end of the vessel. The battery-swappable vessel includes an unlocking device for the battery swapping equipment as described above, and the docking device includes a water connection device and / or an electrical connection device.

[0096] The unlocking lever 2 enables simultaneous unlocking of the waterproof gate on the ship's battery side and subsequent water-electric connection, improving the efficiency of the battery swapping equipment. Simultaneously, the drive mechanism 1 moves the unlocking lever 2 in a predetermined direction, achieving very high unlocking precision, effectively preventing misoperation and significantly improving safety and stability. The unlocking lever 2 applies sufficient pressure to the locking mechanism to ensure unlocking, improving the stability of the unlocking device. After the unlocking lever 2 moves to the point where the locking mechanism is unlocked, the sliding platform 3 continues to move in the docking direction to connect to the battery side for water and / or electrical connections. The unlocking lever 2 compresses the elastic element 4, keeping the unlocking lever 2 stationary while the sliding platform 3 continues to move in the docking direction. This allows for immediate water-electric connection after the ship's battery side is unlocked, ensuring waterproofing and preventing interference with the water-electric connection caused by the unlocking lever 2.
