Description

Technical Field

[0001] This utility model relates to the field of marine power battery pack technology, and in particular to a modular assembly structure for a marine power battery pack. Background Technology

[0002] Ships are a general term for all kinds of vessels. A ship is a means of transportation that can navigate or anchor in waterways for transport or operations. Ships have different technical performance, equipment, and structural types depending on their usage requirements. Ships need to be equipped with battery packs to power the various devices on board.

[0003] In the existing technology, the power supply batteries in ships are assembled in a modular way, connecting multiple battery packs for use. The installation method is to fix the battery packs to the battery rack inside the ship using bolts. However, with this installation method, the area of ​​the battery pack that is restricted is only the part connected to the bolts, and the stress is relatively concentrated, making the connection points prone to deformation and damage. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, the power supply batteries in ships are assembled in a modular way, connecting multiple battery packs for use. The installation method is to fix the battery packs to the battery rack inside the ship using bolts. However, in this way, the area of ​​the battery pack is limited to the part connected to the bolts, and the stress is relatively concentrated, making the connection easy to deform and be damaged. Therefore, this utility model proposes a modular assembly structure for ship power battery packs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a modular assembly structure for a marine power battery pack, comprising a battery pack and a mounting frame, wherein side guide frames are fixedly connected to both sides of the battery pack, a central fixed square tube is fixedly connected to the middle of the mounting frame, and limiting plates are fixedly connected to both sides of the inside of the mounting frame and both sides of the central fixed square tube, a limiting cavity is formed through one side of the limiting plate, a limiting slide plate and a top fixing plate are provided on the inner side of the side guide frames, a limiting protrusion is fixedly connected to one side of the limiting slide plate, one end of the top fixing plate is inclined, and one end of the limiting slide plate is inclined.

[0006] Preferably, an inner limiting plate is fixedly connected inside the side guide frame, and an assembly cavity is opened inside the inner limiting plate, and the limiting slide plate is slidably connected to the assembly cavity.

[0007] Preferably, a limiting baffle is fixedly connected to one side inside the side guide frame, and the limiting baffle is fixedly connected to one end of the inner limiting plate.

[0008] Preferably, a through hole is provided on one side of the limiting baffle, and the through hole communicates with the assembly cavity.

[0009] Preferably, a handle is fixedly connected to the other end of the top plate.

[0010] Preferably, one end of the side guide frame is designed to open, and the thickness of the top fixing plate, the limiting protrusion, and the limiting slide plate are all half the depth of the assembly cavity.

[0011] Preferably, reinforcing angle steels are fixedly connected to both sides of the mounting bracket and the middle of the central square tube, and one side of the reinforcing angle steels is fixedly connected to the limiting plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up the side guide frame and the limiting plate, during installation, after lifting the battery pack, align the limiting plate with the side guide frame and slide the limiting plate into the side guide frame to complete the initial installation. After moving the battery pack to the appropriate position, insert the handle so that the handle squeezes the limiting slide plate, thereby pushing the limiting slide plate to move and causing the limiting protrusion to insert into the limiting cavity, thus completing the installation and fixing. Moreover, this method has a large connection area and disperses the force, preventing excessive local force and resulting in high overall stability. At the same time, the limiting slide plate also squeezes the handle, making it difficult for the handle to move. If the handle does not move, the limiting protrusion and the limiting cavity will remain inserted. This method of installation is less likely to fall off, has higher stability, and is faster to install.

[0014] 2. In this utility model, the thickness of both sides of the battery pack is increased by the cooperation of the side guide frame and the inner limiting plate. When it is hit, only the side guide frame will deform and will not damage the internal structure, thus improving stability. The limiting baffle is used to restrict the position of the limiting plate inside the side guide frame. When one end of the limiting plate contacts the limiting baffle, the limiting cavity and the limiting protrusion are aligned. Inserting the top fixing plate will allow the limiting protrusion to be inserted into the limiting cavity to complete the fixation, making installation more convenient. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 5 As shown, this utility model provides a modular assembly structure for a marine power battery pack, including a battery pack 1 and a mounting frame 2. Side guide frames 3 are fixedly connected to both sides of the battery pack 1. A central fixed square tube 15 is fixedly connected to the middle of the mounting frame 2. Limiting plates 4 are fixedly connected to both sides of the inside of the mounting frame 2 and both sides of the central fixed square tube 15. A limiting cavity 6 is opened through one side of the limiting plate 4. A limiting slide plate 8 and a top fixing plate 11 are provided on the inner side of the side guide frame 3. A limiting protrusion 9 is fixedly connected to one side of the limiting slide plate 8. One end of the top fixing plate 11 is inclined, and one end of the limiting slide plate 8 is inclined.

[0024] The specific settings and functions of this embodiment are described in detail below. With the side guide frame 3 and the limiting plate 4, during installation, after lifting the battery pack 1, the limiting plate 4 is aligned with the side guide frame 3, and the limiting plate 4 is slid into the side guide frame 3 to complete the initial installation. After moving the battery pack 1 to a suitable position, the handle 10 is inserted, causing the handle 10 to press against the limiting slide plate 8, thereby pushing the limiting slide plate 8 to move and causing the limiting protrusion 9 to insert into the limiting cavity 6. This completes the installation and fixation. This method has a large connection area and disperses the force, preventing excessive local force and resulting in high overall stability. Simultaneously, the limiting slide plate 8 also presses against the handle 10, making it difficult for the handle 10 to move. If the handle 10 does not move, the limiting protrusion 9 and the limiting cavity 6 remain connected. This method of installation reduces the likelihood of detachment, increases stability, and makes installation faster.

[0025] Example 2: Figure 1 - Figure 5 As shown, an inner limiting plate 12 is fixedly connected inside the side guide frame 3. An assembly cavity 13 is opened inside the inner limiting plate 12. The limiting slide plate 8 is slidably connected to the assembly cavity 13. A limiting baffle 7 is fixedly connected to one side inside the side guide frame 3. The limiting baffle 7 is fixedly connected to one end of the inner limiting plate 12. A through hole 14 is opened on one side of the limiting baffle 7. The through hole 14 communicates with the assembly cavity 13. A handle 10 is fixedly connected to the other end of the top fixing plate 11. One end of the side guide frame 3 is designed as an open mouth. The thickness of the top fixing plate 11, the limiting protrusion 9, and the limiting slide plate 8 are all half the depth of the assembly cavity 13. Reinforcing angle steels 5 are fixedly connected to both sides of the mounting frame 2 and the middle part of the central fixed square tube 15. One side of the reinforcing angle steel 5 is fixedly connected to the limiting plate 4. The reinforcing angle steels 5 are arranged in an X shape to increase the strength of the mounting frame 2 and increase the support of the limiting plate 4 for the battery pack 1.

[0026] The overall effect of this embodiment is that by cooperating with the side guide frame 3 and the inner limiting plate 12, the thickness of both sides of the battery pack 1 is increased. When it is hit, only the side guide frame 3 will deform, without damaging the internal structure, resulting in higher stability. The limiting baffle 7 is used to limit the position of the limiting plate 4 inside the side guide frame 3. When one end of the limiting plate 4 contacts the limiting baffle 7, the limiting cavity 6 and the limiting protrusion 9 are aligned. Inserting the top fixing plate 11 will allow the limiting protrusion 9 to be inserted into the limiting cavity 6 to complete the fixation, making installation more convenient.

[0027] The usage and working principle of this device are as follows: During installation, first lift the battery pack 1, align the limiting plate 4 with the opening area of ​​the side guide frame 3 and insert it until one end of the limiting plate 4 contacts the limiting baffle 7. Then, insert the inclined end of the top fixing plate 11 into the through hole 14. Through the inclined surface of the limiting slide plate 8 and the top fixing plate 11, the top fixing plate 11 can be promoted to push the limiting slide plate 8, causing the limiting slide plate 8 to move. The limiting protrusion 9 is inserted into the limiting cavity 6, thus completing the installation. Then, connect the wiring. When it is necessary to disassemble the battery pack 1, disconnect the wiring, then hold the handle 10 and pull out the top fixing plate 11. Then, use a screwdriver or metal rod to insert into the limiting cavity 6 and push the limiting protrusion 9 until the limiting protrusion 9 is disengaged from the limiting cavity 6. Then, pull out the battery pack 1.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
