Description

Technical Field

[0001] This utility model relates to the field of electric boat energy supply technology, specifically to an automatic plugging and unplugging device for a box-type power supply for electric boats. Background Technology

[0002] With the rapid development of electric ship technology, box-type power supplies, as an important component of ship propulsion systems, have become crucial for ensuring efficient ship operation through rapid, safe, and automated plugging and unplugging operations. In practical applications, traditional power connection methods often rely on manual operation, resulting in low efficiency, poor safety, and susceptibility to environmental factors, making it difficult to meet the demands of modern electric ships for intelligent and automated energy replenishment.

[0003] In existing technologies, the power supply insertion and removal processes often require manual intervention or employ separate mechanical and electrical actuators, resulting in complex, time-consuming operations with low overall automation. Especially when high precision is required, the rigid connection between the plug and socket can easily generate impact and reaction forces, which can lead to loosening of the contact, poor contact, and short circuits. In severe cases, it can damage connecting components or even the power supply enclosure, affecting equipment lifespan and operational reliability. Furthermore, during electrical connection, exposed live parts pose a risk of electric shock, threatening operator safety; existing devices lack sufficient consideration for electrical isolation and safety protection. After connection, the lack of an effective mechanical locking mechanism can lead to loosening or detachment, especially during ship navigation, where vibration and impact further exacerbate this problem, affecting the stability and continuity of power supply. Simultaneously, existing guidance and positioning systems often lack precision and have high friction, making it difficult to achieve smooth and accurate automatic insertion, increasing failure rates and maintenance costs. Therefore, there is an urgent need for a compact, highly automated, safe, and reliable automatic insertion and removal device. Utility Model Content

[0004] The purpose of this invention is to provide an automatic plugging and unplugging device for a box-type power supply for electric boats, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, an automatic insertion and removal device for a box-type power supply for electric boats is provided, comprising a base, a guide mechanism, a docking mechanism, and an electrical connection assembly. The base is provided with a slide rail extending horizontally. The guide mechanism is slidably connected to the slide rail via a slider. The docking mechanism is mounted above the guide mechanism and connected to the guide mechanism via an elastic buffer assembly. The electrical connection assembly is located at the center of the docking mechanism and includes a plug, a socket, and a drive mechanism. The plug is fixed to the front end of the docking mechanism, the socket is located on the docking surface of the box-type power supply, and the drive mechanism is used to push the docking mechanism to move along the slide rail, causing the plug and socket to engage or disengage. The elastic buffer assembly includes a spring assembly and a limiting rod. The spring assembly surrounds the outside of the limiting rod, one end of which is fixedly connected to the guide mechanism, and the other end passes through the docking mechanism and is provided with an anti-detachment cap.

[0006] Furthermore, the guiding mechanism includes a guide plate and a positioning sensor. The guide plate has several guide rollers on its inner side, which roll in contact with the slider to reduce friction. The positioning sensor is installed at both ends of the guide plate to detect whether the position of the docking mechanism has reached the preset engagement or disengagement point. The feedback signal from the positioning sensor controls the action of the drive mechanism to ensure the accuracy of the engagement and disengagement operations.

[0007] Furthermore, the electrical connection assembly also includes a safety isolation module and a locking mechanism. The safety isolation module is located between the plug and the socket and includes an insulating baffle and an electromagnetic switch. The insulating baffle is in a closed state before insertion to prevent accidental electric shock. When the plug approaches the socket to a set distance, the electromagnetic switch is activated and the insulating baffle is moved away, allowing the plug to be inserted into the socket. The locking mechanism includes a locking pin and a locking hole. The locking pin is installed on the plug, and the locking hole is located inside the socket. When the plug is fully inserted into the socket, the locking pin automatically springs into the locking hole to complete the mechanical locking, ensuring the stability of the insertion state.

[0008] Furthermore, the spring assembly of the elastic buffer component adopts a multi-level stiffness design, with a high-stiffness spring on the side closer to the guide mechanism and a low-stiffness spring on the side farther from the guide mechanism.

[0009] Furthermore, there are multiple guide rollers, which are evenly distributed on the inner surface of the guide plate. Each guide roller is connected to the guide plate through an independent bearing to reduce rolling resistance and extend service life.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a docking mechanism and an elastic buffer component, the docking mechanism is prevented from being damaged or having poor contact due to reaction force during docking; by integrating electrical connection components and mechanical locking mechanisms, fully automatic "electric-mechanical" integrated operation is achieved, eliminating the need for additional electrical actuators and greatly improving the overall integration and automation level; in addition, the design of the safety isolation module effectively protects the safety of operators and avoids the risk of accidental electric shock.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0014] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” and “described” used herein may also include the plural forms. It should be further understood that the word “comprising” as used in this specification means the presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0015] Please see Figure 1-5 As shown, an automatic plugging and unplugging device for a box-type power supply for electric boats is provided.

[0016] As attached Figure 1 As shown, the base 1 serves as the basic structure of the entire device, upon which a slide rail 2 is mounted. The slide rail 2 extends horizontally, providing a stable movement trajectory for the entire device. The guide mechanism is slidably connected to the slide rail 2 via a slider 3, allowing the slider 3 to move smoothly in a straight line along the slide rail 2, thereby driving the docking mechanism 4 to move along the slide rail 2. The docking mechanism 4 is mounted above the guide mechanism and connected to it via an elastic buffer assembly 5. The elastic buffer assembly 5 provides a certain cushioning effect during docking. (See attached diagram) Figure 2 As shown, it includes a spring assembly 9 and a limiting rod 10. The spring assembly 9 surrounds the outside of the limiting rod 10. One end of the limiting rod 10 is fixed to the guide mechanism, and the other end passes through the docking mechanism 4 and is provided with an anti-detachment cap 11. This structure ensures that the elastic buffer assembly 5 will not detach from the limiting rod 10 during compression and rebound.

[0017] The structure of the guiding mechanism is attached Figure 3 The diagram provides a detailed overview, showing that it primarily consists of a guide plate 12 and positioning sensors 14. Multiple guide rollers 13 are evenly distributed on the inner surface of the guide plate 12 and connected to it via independent bearings to reduce rolling resistance and extend service life. The guide rollers 13 roll in contact with the slider 3, reducing friction on the slide rail 2. Positioning sensors 14 are installed at both ends of the guide plate 12 to detect whether the docking mechanism 4 has reached the preset engagement or disengagement point. When the docking mechanism 4 moves to the engagement or disengagement point, the positioning sensors 14 send a feedback signal, and the control system controls the drive mechanism 8 based on the signal, thereby ensuring the accuracy of the engagement and disengagement operations.

[0018] The electrical connection assembly also includes a safety isolation module 15 and a locking mechanism 18. The plug 6 is fixed to the front end of the docking mechanism 4, while the socket 7 is located on the docking surface of the box-type power supply. A drive mechanism 8 is used to push the docking mechanism 4 along the slide rail 2, allowing the plug 6 to engage or disengage from the socket 7. The safety isolation module 15 is located between the plug 6 and the socket 7, and includes an insulating baffle 16 and an electromagnetic switch 17. Before engagement, the insulating baffle 16 is closed to prevent accidental electric shock; when the plug 6 approaches the socket 7 to a set distance, the electromagnetic switch 17 is activated and removes the insulating baffle 16, allowing the plug 6 to be inserted into the socket 7. The locking mechanism 18 includes a locking pin 19 and a locking hole 20. The locking pin 19 is mounted on the plug 6, and the locking hole 20 is located inside the socket 7. When the plug 6 is fully inserted into the socket 7, the locking pin 19 automatically springs into the locking hole 20 to complete the mechanical locking, ensuring the stability of the engagement state. This design not only achieves fully automatic "electromechanical" integrated operation but also significantly improves the overall integration and automation level.

[0019] The design of the elastic buffer component 5 is in the attached Figure 5 Further optimizations were demonstrated, with its spring assembly 9 employing a multi-stage stiffness design. The side closer to the guide mechanism uses a high-stiffness spring, while the side farther from the guide mechanism uses a low-stiffness spring. By using multi-stage stiffness springs, the collision energy generated during the mating process can be absorbed more effectively.

[0020] In practical applications, the specific operating principle of this utility model is as follows: When the electric boat needs to replace its power supply, the box-type power supply is first placed in the docking position, and then the drive mechanism 8 is activated. The drive mechanism 8 pushes the docking mechanism 4 along the slide rail 2 towards the box-type power supply via the slider 3. During this process, the guide roller 13 of the guide mechanism rolls in contact with the slider 3, ensuring the smooth movement of the docking mechanism 4. At the same time, the positioning sensor 14 monitors the position of the docking mechanism 4 in real time. When it approaches the insertion point, the positioning sensor 14 sends a signal, and the control system adjusts the pushing force of the drive mechanism 8 according to the signal, so that the docking mechanism 4 slowly approaches the box-type power supply. When the plug 6 approaches the socket 7 to a set distance, the electromagnetic switch 17 in the safety isolation module 15 is activated, removing the insulating baffle 16 and allowing the plug 6 to be inserted into the socket 7. During the insertion process, the spring group 9 of the elastic buffer assembly 5 begins to function, absorbing the collision energy generated during docking. After the plug 6 is fully inserted into the socket 7, the locking pin 19 of the locking mechanism 18 automatically springs into the lock hole 20 to complete the mechanical locking, and the insertion operation is completed. During the unplugging process, the drive mechanism 8 pushes the docking mechanism 4 in the opposite direction, causing the plug 6 to separate from the socket 7. At the same time, the insulating baffle 16 in the safety isolation module 15 closes again to ensure the safety of the operator.

[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
