Description

Technical Field

[0001] This invention relates to the field of new energy ship battery technology, and in particular to a ship battery swapping positioning device. Background Technology

[0002] When ships are at sea for extended periods or docked in port for long periods, batteries often need to be replaced to ensure safety and efficiency. Traditionally, ship battery replacement is done manually, which is not only time-consuming but also poses certain safety hazards. With technological advancements, battery replacement methods are gradually shifting towards automation and intelligence. Automated battery replacement devices can significantly improve efficiency, reduce manual intervention during the replacement process, and thus lower safety risks.

[0003] In the field of battery positioning for ship battery swapping, existing technologies face numerous problems that urgently need to be addressed. First, traditional positioning devices struggle to achieve precise and stable fixing of batteries. Due to the lack of a multi-dimensional collaborative positioning structure, the turbulence during ship navigation can easily cause horizontal displacement or vertical loosening of the batteries, affecting not only their normal use but also posing safety hazards.

[0004] Secondly, existing positioning technologies generally lack a complete buffer and shock absorption system, which cannot effectively cope with the continuous vibration and impact during ship operation. This causes the battery to be frequently subjected to high-intensity vibration, which accelerates battery aging, shortens its service life, and reduces battery performance reliability.

[0005] In addition, the existing positioning devices are not designed with ease of operation in mind. The battery installation and disassembly process is cumbersome and it is difficult to adapt to batteries of different sizes. Furthermore, the component structure is complex and the degree of modularity is low. During maintenance, it is difficult to quickly locate and replace damaged parts, resulting in high maintenance costs and low efficiency, which seriously restricts the efficient application and operation and maintenance management of ship battery swapping.

These designs effectively reduce the damage to the battery caused by vibration during ship operation, extend battery life, ensure stable battery performance, and improve the reliability of battery swapping in marine applications. 3. Convenient installation and maintenance The device is designed with ease of operation in mind. The pressing stop of the positioning and engaging component facilitates battery removal. The screw and nut structure in the side pressing and downward pressing mechanism makes it easy to adjust the position of the components to accommodate batteries of different sizes. At the same time, the modular design of each component makes the installation process simple. During maintenance, damaged parts can be quickly located and replaced, reducing maintenance difficulty and cost. This improves the practicality and maintainability of the ship battery swapping positioning device, providing convenience for ship battery replacement and daily operation and maintenance. In summary, this ship battery swapping positioning device achieves stable positioning and installation of the battery through the coordinated action of its various structural components.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1: This example provides a ship battery swapping positioning device, see below. Figures 1-11 Specifically, it includes a rectangular frame 100, a piston shock absorber assembly, a positioning and engaging assembly, a side pressing mechanism, and a downward pressing mechanism; The rectangular frame 100 serves as the basic frame of the entire positioning device, used to install and fix other components, providing a stable support structure for the positioning of the battery 200. The rectangular frame 100 contains suspended hollow plates 300. The rectangular frame 100 is connected to the hollow plates 300 through a piston shock-absorbing assembly. The suspended battery 200 is located directly above the hollow plates 300. The hollow plates 300 provide a supporting surface for the battery 200 and are connected to the rectangular frame 100 through the piston shock-absorbing assembly, playing a role in buffering and shock absorption, protecting the battery 200 from vibration during installation and use. One-piece L-shaped corner plates 101 are fixed at the four corners of the top surface of the rectangular frame 100. Each L-shaped corner plate 101 is connected to the battery 200 through a positioning and engaging assembly. The L-shaped corner plates 101 are fixed at the four corners of the top surface of the rectangular frame 100 to install the positioning and engaging assembly. The positioning and engaging assembly is used to initially position and fix the battery 200 to prevent the battery 200 from shifting in the horizontal direction. When the battery 200 is installed, the engaging end 106 can be engaged into the positioning slot 202 of the battery 200 to fix the battery 200 and prevent the battery 200 from falling out of the positioning device in the vertical direction. When it is necessary to remove the battery 200, pressing the pressing stop 107 can make the reset swing arm 105 swing and move the engaging end 106 out of the positioning slot 202. A pair of symmetrically distributed first U-shaped brackets 400 are fixed on the left and right sides of the top surface of the rectangular frame 100. Each first U-shaped bracket 400 has an L-shaped swing arm 401 that is movably hinged in its opening. Each L-shaped swing arm 401 is connected to the battery 200 through a side pressing mechanism. The first U-shaped brackets 400 are fixed on the left and right sides of the top surface of the rectangular frame 100 to provide hinged support points for the L-shaped swing arms 401, so that the L-shaped swing arms 401 can swing around them. The L-shaped swing arm 401 is connected to the battery 200 through the side pressing mechanism. When the battery 200 is installed, as the battery 200 falls, the L-shaped swing arm 401 tilts and swings inward, causing the side pressing block 410 to press against the elliptical groove 201 of the battery 200, thereby clamping and positioning the side of the battery 200 and preventing the battery 200 from shaking in the horizontal direction. A pair of symmetrically distributed second U-shaped brackets 500 are fixed on the front and rear sides of the top of the rectangular frame 100. An L-shaped bending swing arm 501 is engaged in the opening of each second U-shaped bracket 500. Each L-shaped bending swing arm 501 is connected to the battery 200 through a pressing mechanism. The second U-shaped brackets 500 are fixed on the front and rear sides of the top of the rectangular frame 100 to provide a position for the L-shaped bending swing arm 501 to be installed and supported, so that the L-shaped bending swing arm 501 can swing around the limiting pin 503. The L-shaped bending swing arm 501 is connected to the battery 200 through a pressing mechanism. When the battery 200 is installed, as the battery 200 falls, the L-shaped bending swing arm 501 first tilts downward and then falls vertically downward, causing the pressing block 506 to press against the top surface of the battery 200, thereby pressing and positioning the top surface of the battery 200 and preventing the battery 200 from loosening in the vertical direction.

[0021] In the specific implementation process, such as Figure 8 and Figure 9As shown, the piston damping assembly includes a piston sleeve 305 and a piston slide rod 303. Fixing plates 304 are fixed at the four bottom corners of the rectangular frame 100. The fixing plates 304 are used to fix the piston sleeves 305, ensuring a stable connection between the piston damping assembly and the rectangular frame 100. Vertically distributed piston sleeves 305 are fixed on the top surface of each fixing plate 304. T-shaped connecting plates 302 are fixed at the four corners of the hollow plate 300, connecting the hollow plate 300 and the piston slide rod 303. The piston slide rod 303 enables the hollow plate 300 to move up and down through the cooperation of the piston slide rod 303 and the piston sleeve 305. Each T-shaped connecting plate 302 has vertically distributed piston slide rods 303 fixed on its bottom surface, and the bottom end of each piston slide rod 303 is slidably inserted into the corresponding piston sleeve 305. The piston slide rod 303 can slide within the piston sleeve 305, which serves to guide and restrict the movement direction of the hollow plate 300, ensuring the stability of the hollow plate 300's up and down movement.

[0022] It should be noted that in this embodiment, a piston spring 306 is sleeved between adjacent piston sleeves 305 and piston slide rods 303. The upper and lower ends of the piston spring 306 are respectively fixed to the T-shaped connecting plate 302 and the fixing plate 304. When the battery 200 is installed or subjected to vibration, the piston spring 306 absorbs and releases energy through compression and extension, playing a role in buffering and shock absorption, reducing the impact of vibration on the battery 200, and protecting the performance and life of the battery 200.

[0023] Example 2: Based on Example 1, this example also includes: In the specific implementation process, such as Figure 6 and Figure 7 As shown, the positioning and engaging assembly includes a reset swing arm 105 and an engaging end 106. A pair of diagonally distributed rectangular through holes 102 are provided in the middle of the two side walls of the L-shaped corner plate 101. The bottom outer port of the rectangular through hole 102 is chamfered at sixty degrees. A reset shaft 104 is rotatably inserted into the bottom of the rectangular through hole 102. The reset shaft 104 provides the axis of rotation for the reset swing arm 105, so that the reset swing arm 105 can swing around it. The reset swing arm 105 is fixed in the middle of the reset shaft 104. The bottom of the outer side of the battery 200 has eight pairs of vertically distributed positioning slots 202 and positioning notches 203, and the positioning notches 203 are chamfered at a 45-degree angle. The inner side of the top end of the reset swing arm 105 is fixed with a locking end 106, and the locking end 106 slides and abuts against the positioning slot 202. The outer side of the bottom end of the reset swing arm 105 is fixed with a pressing stop 107. The pressing stop 107 facilitates the operator to manually operate the reset swing arm 105 to separate the locking end 106 from the positioning slot 202, which facilitates the disassembly of the battery 200. A pair of reset through holes 103 are provided on both sides of the rectangular through hole 102. The rectangular through hole 102 provides space for the swing of the reset swing arm 105. The reset through holes 103 are used to install the reset shaft 104 to ensure the rotational flexibility of the reset shaft 104. The two ends of the reset shaft 104 are rotatably inserted into the pair of reset through holes 103. A pair of symmetrically distributed torsion springs 108 are sleeved on the two ends of the reset shaft 104. One end of the torsion spring 108 is fixed to the reset shaft 104, and the other end is fixed to the inner wall of the reset through hole 103. The torsion spring 108 provides the reset power for the reset swing arm 105, so that the reset swing arm 105 can remain vertically flush with the rectangular through hole 102 when there is no external force, ensuring that the locking end 106 can be accurately locked into the positioning slot 202.

[0024] Example 3: Based on Example 2, this example also includes: In the specific implementation process, such as Figure 9 and Figure 10 As shown, the side-pressure mechanism includes a fixing screw 409 and a side-pressure block 410. Vertically distributed elliptical grooves 201 are provided in the middle of the left and right sides of the battery 200. A threaded hole is provided at the top of the L-shaped swing arm 401. A threaded fixing screw 409 is screwed into the threaded hole. A threaded fixing nut 411 is fitted onto the outer end of the fixing screw 409. A side-pressure block 410 is fixed to the inner end of the fixing screw 409. The side-pressure block 410 slides against the corresponding elliptical groove 201. The fixing screw 409 can adjust the position of the side-pressure block 410 so that it can tightly abut against the elliptical groove 201 of the battery 200, achieving clamping of the side of the battery 200, enhancing the positioning effect of the battery 200, and locking the fixing screw 409 to prevent loosening during use and ensure the stability of the side-pressure block 410's position. A rectangular notch 301 is provided in the middle of each of the four side walls of the hollow plate 300. A through-type fixed pin is fixed at the corner of the L-shaped swing arm 401. The two ends of the fixed pin are rotatably inserted into the top of the opening of the first U-shaped bracket 400. A U-shaped ear seat 402 with the opening facing downward is fixed at the bottom end of the L-shaped swing arm 401. A hinged connecting rod 403 is provided in the opening of the U-shaped ear seat 402. The bottom end of the hinged connecting rod 403 is hinged in the rectangular notch 301 on the same side. The U-shaped ear seat 402 and the hinged connecting rod 403 are hinged to form a linkage relationship between the L-shaped swing arm 401 and the hollow plate 300. When the L-shaped swing arm 401 swings, the hollow plate 300 is driven to move downward through the hinged connecting rod 403, thereby buffering and shock absorption of the battery 200. The top surface of the U-shaped ear seat 402 is fixed with a vertically distributed first connecting plate 404. A pair of first sliding holes are opened at both ends of the first connecting plate 404. A parallel rubber support plate 405 is provided above the first connecting plate 404. The top surface of the rubber support plate 405 is pressed against the bottom surface of the battery 200. The rubber support plate 405 contacts the bottom surface of the battery 200, which plays the role of buffering and protecting the battery 200. A pair of first screws 406 are fixed on both sides of the bottom surface of the rubber support plate 405. The bottom end of each first screw 406 is slidably inserted into the corresponding first sliding hole, and the bottom end of each first screw 406 is fitted with a threaded locking first nut 408. The upper half of each first screw 406 is fitted with a first buffer spring 407. The combination of the first screws 406, the first nuts 408 and the first buffer springs 407 can adjust the height and buffering force of the rubber support plate 405 to adapt to batteries 200 of different sizes and weights, and provide a buffering effect when the battery 200 is subjected to vibration.

[0025] Example 4: Based on Example 3, this example also includes: In the specific implementation process, such as Figure 9 and Figure 11 As shown, the L-shaped bending swing arm 501 has an L-shaped bending pin hole 502 at the bending point. The L-shaped bending pin hole 502 is slidably engaged with a through-distributed limiting pin 503 inside. The two ends of the limiting pin 503 are fixedly inserted into the top of the opening of the second U-shaped bracket 500, and the bottom end of the L-shaped bending swing arm 501 is hinged to a rectangular notch 301 on the same side. The pressing mechanism includes a second screw 505 and a pressing block 506. The top end of the L-shaped bent swing arm 501 is fixed with a vertically distributed second connecting plate 504. The two ends of the second connecting plate 504 are provided with a pair of second sliding holes. A second screw 505 is slidably inserted into the interior of each second sliding hole. The second screw 505 can adjust the position of the pressing block 506 so that the pressing block 506 can be tightly pressed against the top surface of the battery 200, thereby pressing the top surface of the battery 200 and enhancing the positioning effect of the battery 200. Each second screw 505 has a threaded locking second nut 507 fitted at its top end. The second nut 507 is used to lock the second screw 505 to prevent it from loosening during use and to ensure the stability of the position of the pressure block 506. Each second screw 505 has a second buffer spring 508 fitted on its lower half. Each second screw 505 has a pressure block 506 fixed at its bottom end. The bottom surface of each pressure block 506 is pressed against the top surface of the battery 200. When the battery 200 is subjected to vibration or external force, the second buffer spring 508 can absorb and release energy through compression and extension, playing a role in buffering and shock absorption and protecting the top surface of the battery 200 from damage.

[0026] Specifically, the working principle and operation method of this invention are as follows: In the initial state before the battery 200 is installed, under the tension of the piston spring 306, the piston slide rod 303 is driven to slide upward along the piston sleeve 305, so that the hollow plate 300 is kept in a high position. Under the hinge action of the hinge link 403 and the U-shaped ear seat 402, the L-shaped swing arm 401 is driven to be in an outward tilting state along the first U-shaped bracket 400, and the L-shaped bent swing arm 501 is in an outward tilting state along the limiting pin 503. When installing the battery 200, the battery 200 is slowly placed between the four L-shaped corner plates 101. Under the action of the torsion spring 108, the reset swing arm 105 is always vertically aligned with the rectangular through hole 102. When the battery 200 descends, the engaging end 106 will first abut against the positioning notch 203. The engaging end 106 is driven by the force to swing the reset swing arm 105 outward along the reset shaft 104. As the battery 200 continues to fall, the engaging end 106 slides along the outer wall of the battery 200 and engages in the positioning slot 202. At the same time, when the battery 200 falls, the bottom surface of the battery 200 will contact a pair of rubber support plates 405, and drive the rubber support plates 405, the first connecting plate 404 and the L-shaped swing arm 401 to tilt and swing inward along the first U-shaped bracket 400, thereby driving the side pressure block 410 to press against the elliptical groove 201, and through the hinged connecting rod 403, drive the hollow plate 300 to be forcefully moved downward. The L-shaped bending swing arm 501 is driven to fall downwards in sync. Under the limiting action formed by the limiting pin 503 and the L-shaped bending pin hole 502, the L-shaped bending swing arm 501 first tilts downwards, and then falls downwards in a vertical state. It also drives the pressing block 506 to press against the top surface of the battery 200 through the second connecting plate 504. This completes the positioning and installation of battery 200.

[0027] In summary, this ship battery swapping positioning device achieves stable positioning and installation of the battery 200 through the coordinated action of its various structural components. It also has good buffering and shock absorption performance, which can effectively protect the battery 200 from vibration and external forces during use, and realize the rapid positioning, shock absorption and stable fixation of the battery 200.
