Description

Technical Field

[0001] This utility model is a cross-type battery clip structure, belonging to the field of battery technology. Background Technology

[0002] In the process of ship electrification (such as pure electric ships and hybrid ships), battery packs serve as the core power source or energy storage unit. Due to the stringent energy density and power output requirements of ships' power systems (e.g., inland waterway cargo ships need continuous power to support heavy-load navigation, and sightseeing boats need to ensure all-day operation), the capacity and power of a single battery pack often cannot meet these demands. Therefore, battery pack stacking has become the mainstream design scheme for ship battery systems. In current ship battery pack stacking applications, adjacent rows of battery packs generally adopt an end-to-end arrangement, meaning that within the same stacking plane, the ends of the previous row of battery packs are directly opposite the ends of the next row, forming a head-to-tail connection. In this layout, the compartment area occupied by one layer of battery packs is completely equivalent to the simple sum of the bottom areas of all individual battery packs in that layer. However, ship compartment space is inherently scarce and fixed due to limitations imposed by the overall hull structure, load balance, and other equipment installation requirements, making expansion impossible. Ultimately, this significantly reduces the number of battery packs that can be accommodated within the limited compartment space, hindering the improvement of energy reserves in ship electrification systems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cross-type battery snap-fit ​​structure to solve the problems mentioned in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cross-type battery clip structure, comprising: The first housing has a first flat shell portion installed at one end. The first flat shell portion is recessed at two corners away from the first housing to form a first snap-fit ​​hole, and the first housing is recessed at two corners away from the first flat shell portion to form a second snap-fit ​​hole. The second housing maintains a fixed relative position with the first housing. One end of the second housing is equipped with a second flat shell portion that mates with the first flat shell portion. At the two corners of the side of the second flat shell portion facing away from the first flat shell portion, there are detachable first snap-fit ​​posts that mate with the first snap-fit ​​holes. At the two corners of the second housing away from the second flat shell portion, there are detachable second snap-fit ​​posts that mate with the second snap-fit ​​holes.

[0005] Furthermore, the two corners of the second flat shell portion away from the second shell are recessed to form a first countersunk hole. One end of the first snap-fit ​​post is inserted into the first countersunk hole, and the end of the first snap-fit ​​post inside the first countersunk hole is fitted with a first rubber sleeve. The first rubber sleeve fits against the inner wall of the first countersunk hole.

[0006] Furthermore, the second housing has two recessed corners away from the first flat shell portion to form second countersunk holes. One end of the positioning locking post is inserted into the second countersunk hole, and a second rubber sleeve is fitted onto the end of the second locking post in the second countersunk hole. The second rubber sleeve fits against the inner wall of the second countersunk hole.

[0007] Furthermore, both the first and second snap-fit ​​posts are hollow structures.

[0008] Furthermore, the side of the first housing away from the first flat shell portion is recessed to form a first groove for installing the battery socket, and the side of the second housing away from the second flat shell portion is recessed to form a second groove that mates with the first groove.

[0009] Furthermore, the first housing has multiple first notches recessed at equal intervals on the two sides adjacent to the first flat shell portion, and the second housing has multiple second notches recessed at equal intervals on the two sides adjacent to the second flat shell portion, which cooperate with the first notches recessed.

[0010] Furthermore, the first flat shell portion and the first shell portion are integrally formed, and the second flat shell portion and the second shell portion are integrally formed.

[0011] Furthermore, the first shell and the second shell together form an outer shell portion, and the first flat shell portion and the second flat shell portion together form an overlapping portion, with one overlapping portion on the shell portion being inserted between two adjacent overlapping portions.

[0012] The beneficial effects of this utility model are: The outer shell, composed of the first and second shells, and the overlapping section, composed of the first and second flat shells, allow the overlapping sections of adjacent outer shells to interpenetrate. That is, the overlapping section of one outer shell can be inserted between the overlapping sections of two adjacent outer shells. This means that the battery packs on the same stacked plane are no longer simply arranged end to end, but rather the space is utilized through the nesting of the overlapping sections. This cross-layout breaks the traditional limitation that the area of ​​one layer is equal to the sum of the areas of all battery packs, effectively compressing the gaps between adjacent battery packs. This significantly increases the number of battery packs that can be accommodated in the limited cabin space of the ship, thereby improving the overall battery capacity and providing a basic support for upgrading the ship's range.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1-5 This utility model provides a technical solution: a cross-type battery snap-fit ​​structure, including a first housing 1, a first flat shell portion 11 integrally formed with the first housing 1 at one end, first snap-fit ​​holes 12 recessed at two corners of the first flat shell portion 11 away from the first housing 1, and second snap-fit ​​holes 14 recessed at two corners of the first housing 1 away from the first flat shell portion 11. A second housing 2 maintains a fixed relative position to the first housing 1, and a second flat shell portion 24 cooperating with the first flat shell portion 11 is installed at one end of the second housing 2. The second flat shell portion 24 is integrally formed with the second housing 2, and detachable first snap-fit ​​posts 21 cooperating with the first snap-fit ​​holes 12 are installed at two corners of the side of the second flat shell portion 24 facing away from the first flat shell portion 11. At the two corners of the housing 2 away from the second flat shell 24, there are detachable second snap-fit ​​posts 23 that mate with the second snap-fit ​​holes 14. Both the first snap-fit ​​post 21 and the second snap-fit ​​post 23 are hollow structures. The first snap-fit ​​post 21 of the second flat shell 24 is precisely engaged with the first snap-fit ​​hole 12 of the adjacent first flat shell 11, and the second snap-fit ​​post 23 of the second housing 2 is precisely engaged with the second snap-fit ​​hole 14 of the adjacent first housing 1, forming a multi-point snap-fit ​​limit. On the one hand, it can ensure that the battery packs after cross-over overlap remain in a constant relative position, avoiding misalignment or displacement of the battery packs due to ship turbulence. On the other hand, the snap-fit ​​structure does not require additional welding or bolt fixing, is easy to install, and has high connection strength. It can withstand the lateral and longitudinal impacts and vibrations of the ship, ensuring the structural stability of the battery pack stacking system.

[0016] See Figures 1-5 The first shell 1 and the second shell 2 together form the outer shell of the battery pack, and the first flat shell 11 and the second flat shell 24 together form the overlapping part. An overlapping part on one outer shell is inserted between two adjacent overlapping parts. The first shell 1 and the second shell 2 are spliced ​​together to form the outer shell for accommodating the batteries. Simultaneously, the cooperation of the first flat shell 11 and the second flat shell 24 forms an overlapping part for connecting adjacent units. In shipboard battery pack stacking operations, adjacent overlapping parts can be flexibly interlocked. Specifically, a single overlapping part can be embedded between two adjacent overlapping parts, freeing the battery packs in the same stacking plane from the constraints of traditional end-to-end arrangement. This design, through the nesting relationship of the overlapping parts, allows the battery packs to form a spatially staggered distribution in the plane, no longer limiting the total area of ​​a single stack to a simple superposition of the bottom areas of all battery packs. In traditional end-to-end layouts, the large number of ineffective gaps reserved between adjacent battery packs due to installation and maintenance requirements are effectively compressed and transformed into usable carrying space through staggered layout. For ships whose cabin space is limited by hull structure, load balance and other equipment installation requirements and cannot be expanded at will, this cross layout can significantly increase the number of battery packs that can be accommodated in the limited cabin, thereby increasing the overall energy reserve of the ship's battery system. This provides core structural support for upgrading the ship's range and effectively solves the pain points of low space utilization and insufficient battery capacity under the traditional stacking method.

[0017] See Figure 1 , Figure 2 and Figure 4 The second flat shell portion 24 has two recessed corners away from the second shell portion 2, forming a first countersunk hole 25. One end of the first locking post 21 is inserted into the first countersunk hole 25. The end of the first locking post 21 inside the first countersunk hole 25 is fitted with a first rubber sleeve. The first rubber sleeve fits against the inner wall of the first countersunk hole 25. The second shell portion 2 has two recessed corners away from the first flat shell portion 11, forming a second countersunk hole 26. One end of the second locking post 23 is inserted into the second countersunk hole 26. The end of the second locking post 23 inside the second countersunk hole 26 is fitted with a second rubber sleeve. The second rubber sleeve fits against the inner wall of the second countersunk hole 26. The first rubber sleeve of the first locking post 21 and the second rubber sleeve of the second locking post 23 fit tightly against the inner walls of the first countersunk hole 25 and the second countersunk hole 26, respectively, to prevent the first locking post 21 and the second locking post 23 from falling off at will.

[0018] See Figure 1 and Figure 2The first housing 1 has a recessed side away from the first flat shell portion 11 to form a first groove for installing the battery socket. The second housing 2 has a recessed side away from the second flat shell portion 24 to form a second groove that matches the first groove. Multiple first notches 13 are recessed at equal intervals on the two adjacent sides of the first housing 1 and the first flat shell portion 11. Multiple second notches 22 are recessed at equal intervals on the two adjacent sides of the second housing 2 and the second flat shell portion 24 to match the first notches 13. The first notches 13 and the second notches 22 cooperate with each other. After cross-stacking, the contact area of ​​the outer shell of the battery pack formed by the two adjacent first housings 1 and the second housing 2 is reduced, thereby reducing the risk of thermal runaway.
