[0002] With increasing global emphasis on environmental protection and sustainable development, the shipbuilding industry is facing an urgent need to reduce carbon emissions and improve energy efficiency. The application of marine power battery compartments is becoming widespread. However, in existing battery compartments, the battery lock and electrical connector are fixed to the same base. When the battery is lifted together with the base using a battery swapping machine, the connecting wires of the base are pulled up, causing damage to the wires and connectors. Furthermore, because the space inside the battery compartment is limited, personnel cannot access it. If the battery lock malfunctions, the battery cannot be removed from the battery compartment.
[0003] Utility model patent CN119481547A, published on February 18, 2025, discloses a connector base, connector, and battery pack. The connector base includes a base body for fixing to a battery pack. The base body has a plug-in portion with two symmetrically connected lugs on opposite outer surfaces. The lugs connect to the handle of a handle plug. Two protrusions are also fixedly mounted on the base body, located on either side of the plug-in portion and corresponding to the lugs, spaced apart from the plug-in portion. Each protrusion has a screw hole aligned with a positioning hole of a locking bolt plug for screwing in a bolt to securely connect the locking bolt plug to the protrusion. However, this connector base, connector, and battery pack do not solve the aforementioned technical problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a battery lock and connector detachable battery base that facilitates battery removal from the battery compartment and avoids damage to connecting wires and connectors during battery lifting.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] The battery lock and connector detachable battery base includes a lock body base and a connector base. The lock body base is detachably connected to the connector base. The lock body base is provided with a positioning structure, and the connector is located in the middle of the lock body base.
[0007] A pad is fixedly connected to the bottom of the lock body base. The connector base includes a support base. Bolts are connected to the ends of the pad and the support base. The bolts are located on both sides of the lock body base.
[0008] The positioning structure includes a guide block and a positioning pin, both of which are located on the edge of the lock body base. A cylinder is provided on one side of the guide block, and the cylinder is horizontally positioned. The battery lock includes a pin, which is connected to the output end of the cylinder and extends out from the other side of the guide block.
[0009] Two support bases are provided, and a crossbeam is fixedly connected between the two support bases. A platform is provided in the middle of the crossbeam, and a flat plate is provided above the platform. The connectors are evenly distributed on the flat plate. The flat plate is connected to the platform by connecting bolts, which pass through the platform. A buffer spring is sleeved on the outside of the connecting bolts. The connecting bolts are evenly distributed, and the two ends of the buffer spring contact the flat plate and the connector base, respectively.
[0010] The top of the guide block is inclined, and the positioning pin is vertically positioned.
[0011] The lock body base is equipped with pads.
[0012] The lock body base is made of welded square tubing, and the support base is an I-beam structure.
[0013] The support base is fixedly connected to a reinforcing rib.
[0014] The technical advantages of this utility model are as follows: The battery lock and connector are separated in this utility model's battery base. The lock base and connector base are connected by bolts to form a detachable connection. Designed as independent lock base and connector base, compared to traditional battery bases, the battery lock and connector are functionally separated, achieving a split-structure design. When the battery and lock base are lifted out of the battery compartment as a whole, mechanical damage to the connecting wires and connector is avoided during battery lifting, solving the problem of connecting wire pulling caused by the existing fixed-integral design. The detachable connection between the lock base and connector base also allows for quick disassembly and separation in case of lock failure, facilitating battery removal, providing feasibility for emergency maintenance, and reducing the risk of battery jamming due to lock failure.

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.
[0022] like Figures 1 to 4 As shown, the battery lock and connector detachable battery base includes a lock body base 1 and a connector base 2. The lock body base 1 is detachably connected to the connector base 2. The lock body base 1 is provided with a positioning structure, and the connector 4 is located in the middle of the lock body base 1.
[0023] The battery is placed on the lock body base 1, providing support. The battery connector 4 is placed on the connector base 2 for connection to the battery charging / discharging port. The connector base 2 is connected to the lock body base 1 by bolts 10. The connector 4 is located in the middle of the lock body base 1. When the battery and the lock body base 1 fall onto the connector base 2, the battery charging / discharging port can correspond and engage with the connector 4. The battery lock is independently set on the lock body base 1, while the electrical connector 4 is independently set on the connector base 2. Because the lock body base 1 and the connector base 2 adopt a separate structure, the coupling of the battery lock and electrical connection functions is avoided. When the battery needs to be lifted out of the battery compartment, first remove the bolts 10 on the pad 9. Under the fixing of the battery lock and the limiting action of the guide block 7 and the positioning pin 8, the battery and the lock body base 1 are lifted out of the battery compartment as a whole. Because the lock body base 1 and the connector base 2 are separated, the problems of pulling on the connecting wires and damage to the connector 4 are avoided. At the same time, the buffer seat outside the battery compartment also adopts the same structure as the connector base 2, which facilitates the connection with the connector 4 after the battery is lifted out.
[0024] like Figure 1 and Figure 4As shown, a pad 9 is fixedly connected to the bottom of the lock body base 1. The connector base 2 includes a support 3. Bolts 10 are connected to the ends of the pad 9 and the support 3, and the bolts 10 are located on both sides of the lock body base 1. The bolts 10 on the pad 9 are used with a specially designed extended hex wrench 18. Because the bolts 10 are located on both sides of the lock body base 1, it provides operating space for the use of the specially designed extended hex wrench 18, making it convenient to remove the battery from the battery compartment. The top of the specially designed extended hex wrench 18 is T-shaped, which makes it easy for personnel to rotate and apply force. When in use, it is in a vertical position, which can avoid contact with the battery compartment and the battery. The method of using the specially designed extended hex wrench 18 to remove the bolts 10 solves the maintenance problem of not being able to enter the confined space manually, and provides a solution for emergency faults. When the battery lock malfunctions and cannot be retracted, the solution is as follows: Use an extended, specially made hex wrench to unscrew the connecting bolt 15, detaching the lock body base 1 from the connector base 2. At this point, the battery can be lifted out of the battery compartment using a battery swapping robot, thus solving the technical problem of the battery being unable to be removed in a confined space.
[0025] like Figure 1 and Figure 2 As shown, the positioning structure includes a guide block 7 and a positioning pin 8, both located on the edge of the lock body base 1. A cylinder 5 is horizontally positioned on one side of the guide block 7. The battery lock includes a pin 6, which connects to the output end of the cylinder 5 and extends from the other side of the guide block 7. In this structure, the guide block 7 provides initial guidance for battery placement, facilitating proper battery placement. The positioning pin 8 precisely guides and positions the battery, accurately constraining its horizontal displacement. The combined design of the guide block 7 and the positioning pin 8 forms a layered guiding system, ensuring high-precision positioning during battery installation, improving battery installation efficiency and stability, and reducing lock body wear and mismatched connectors caused by positioning deviations. The battery lock uses the horizontally positioned cylinder 5 to power the pin 6, which extends into the fixing hole inside the battery, thus constraining the battery's vertical movement, ensuring stable battery fixation and posture, and guaranteeing smooth charging and discharging. Throughout the process of the battery being lifted from the battery compartment and placed on the connector base 2 by the battery swapping robot along with the lock body base 1, the battery's posture remains stable.
[0026] like Figure 3As shown, there are two support bases 3, and a crossbeam 11 is fixedly connected between the two support bases 3. A platform 12 is provided in the middle of the crossbeam 11, and a flat plate 13 is provided above the platform 12. Connectors 4 are evenly distributed on the flat plate 13. Connecting bolts 15 are used to connect the flat plate 13 and the platform 12. The connecting bolts 15 pass through the platform 12, and buffer springs 14 are sleeved on the outside of the connecting bolts 15. The connecting bolts 15 are evenly distributed, and the two ends of the buffer springs 14 contact the flat plate 13 and the connector base 2, respectively. The two support bases 3 provide a stable foundation for the connector base 2 to support the battery and the lock body base 1. The connector 4 includes a charging port and a discharging port. The buffer springs 14 are placed at the bottom of the battery to provide a buffering effect, ensuring that the connector 4 accurately engages with the battery charging and discharging ports.
[0027] like Figure 1 As shown, the top of the guide block 7 is inclined, and the positioning pin 8 is vertically positioned. The inclined part of the guide block 7 provides initial guidance during the battery placement process, and the above structure does not interfere with the vertical lifting process of the battery swapping robot.
[0028] like Figure 2 As shown, the lock body base 1 is provided with pads 16. The lock body base 1 is provided with multiple pads 16 to further ensure the horizontal stability of the battery after it is placed.
[0029] like Figures 1 to 3 As shown, the lock body base 1 is constructed from welded square tubing, and the support base 3 is an I-beam structure. The lock body base 1 and the support base 3 have simple structures, low manufacturing costs, and reliable support strength.
[0030] like Figure 3 As shown, a reinforcing rib 17 is fixedly connected to the side of the support base 3. The reinforcing rib 17 is used to further improve the structural strength of the support base 3 and increase the service life of the connector base 2.
[0031] This battery lock features a detachable battery base with separate lock body and connector. The lock body base 1 and connector base 2 are connected by bolts 10 to form a detachable connection. Designed as independent lock body base 1 and connector base 2, compared with traditional battery bases, the battery lock and connector 4 are functionally separated and achieve a split structure design. When the battery and lock body base 1 are lifted out of the battery compartment as a whole, mechanical damage to the connecting wires and connector 4 is avoided during battery lifting, solving the problem of connecting wire pulling caused by the existing fixed integration. The detachable connection between lock body base 1 and connector base 2 also allows for quick disassembly and separation in case of lock failure, facilitating battery removal, providing the feasibility of emergency maintenance, and reducing the risk of battery jamming due to lock failure.
[0032] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
