Description

Technical Field

[0001] This utility model relates to the field of battery box technology, and in particular to a battery box body that can accommodate batteries of various sizes. Background Technology

[0002] In modern energy systems, batteries, as core devices for energy storage and release, are widely used in transportation, power storage, and industry. From the starting power source for gasoline vehicles to the drive system of electric vehicles, and then to the energy storage unit for solar power generation, they achieve efficient conversion and stable supply of electrical energy through chemical energy. In daily life, a single battery often exists as a basic unit. However, when applications expand to high-power equipment, industrial units, or new energy storage systems, the coordinated operation of multiple battery packs becomes a necessity. By integrating dispersed battery units into a unified whole, it not only provides physical protection and optimized heat dissipation, but also extends the battery pack's lifespan through functions such as equal charging and overvoltage protection, while also meeting the needs of modular expansion. From vehicle power systems to grid-scale energy storage devices, battery boxes are becoming a key bridge connecting individual energy storage and large-scale energy applications.

[0003] Existing battery boxes achieve collaborative management of multiple batteries through a modular architecture, combining individual batteries into battery packs using parallel or series connections. This design allows the battery box to adapt to the power requirements of different scenarios such as electric vehicles and energy storage power stations, and enables rapid replacement and expansion through standardized interfaces, forming a complete working loop from individual battery protection to system control.

[0004] However, while existing battery boxes can integrate individual battery units into a single unit, this method typically requires batteries of the same specifications to ensure secure installation within the box. This makes existing battery boxes often unsuitable for installing batteries of various sizes. This is mainly due to differences in length, width, height, and terminal positions between different brands or models of batteries. Traditional battery boxes have mounting brackets, slots, and screw holes designed according to specific specifications, which can lead to problems such as excessive gaps, misaligned terminals, or insecure mounting during installation. This reliance on a single specification results in insufficient flexibility for various usage scenarios, making it difficult to meet diverse needs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a battery box that can accommodate batteries of multiple specifications, aiming to improve the problem that traditional battery boxes can only accommodate batteries of a single specification and are difficult to cope with various usage scenarios.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a battery box body capable of installing batteries of various specifications, comprising a box, wherein an installation component is provided inside the box; The mounting assembly includes a mounting plate, the lower surface of which is fixedly connected to the inside of the box. The upper surface of the mounting plate has mounting holes. A battery is attached to the upper surface of the mounting plate. Fixing plates are fixedly connected to both sides of the outer wall of the battery. A housing is attached to the upper surface of the fixing plate. A fixing post is slidably connected inside the housing. A first fixing block is fixedly connected to the lower end of the fixing post. A limit block is fixedly connected to the outer wall of the fixing post. A first spring is attached to the outer wall of the fixing post. One end of the first spring is fixedly connected to the inside of the housing, and the other end is fixedly connected to the outer wall of the limit block.

[0007] Furthermore, a sliding plate is slidably connected inside the box, and a buckle is fixedly connected to the outer wall of the sliding plate. A second spring is provided on the lower surface of the sliding plate, with one end of the second spring fixedly connected inside the box and the other end of the second spring fixedly connected to the lower surface of the sliding plate.

[0008] Furthermore, a handle is rotatably connected to the outer wall of the box, and an irregularly shaped block is fixedly connected inside the box.

[0009] Furthermore, a connecting rod is rotatably connected to the outer wall of the sliding plate, a connecting column is fixedly connected to the outer wall of the connecting rod, and the outer wall of the connecting column is slidably connected to the outer wall of the irregular block.

[0010] Furthermore, a lid is rotatably connected to one side of the outer wall of the box, and a second fixing block is fixedly connected to the outer wall of the lid, with the outer wall of the second fixing block fitting against the inner wall of the buckle.

[0011] Furthermore, the limiting block is disposed inside the outer casing.

[0012] Furthermore, the outer wall of the first fixing block is rotatably connected to the inside of the mounting hole.

[0013] Furthermore, the outer wall of the fixed column is slidably connected to the fixed plate and the mounting hole.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the battery is placed on the mounting plate inside the box, and then the fixing plate is aligned with the mounting hole. The outer shell is placed on the fixing plate, allowing the first fixing block to pass through the fixing plate. Then, the fixing post is pressed down, causing the first fixing block to slide downward in the mounting hole while compressing the first spring. By rotating the fixing post, the first fixing block is rotated until it can no longer align with the mounting hole on the upper surface of the mounting plate. This allows the fixing post to firmly fix the fixing plate to the upper surface of the mounting plate, thereby realizing the installation of the battery. At the same time, this fixing method can also install batteries of different specifications, solving the problem that traditional battery boxes can only install batteries of a single specification and are difficult to cope with various usage scenarios.

[0015] 2. In this utility model, by rotating and pressing down the cover, the second fixing block moves downward and fits against the outer wall of the buckle. By continuing to press the cover downward, the second fixing block moves downward against the buckle, thereby driving the sliding plate to slide downward. At this time, during the downward movement of the buckle, due to the narrowing of the internal space, the buckle undergoes elastic deformation and moves inward, thereby firmly locking the second fixing block. By causing the sliding plate to slide downward, the connecting post slides into the groove of the outer wall of the irregular block, while compressing the second spring to fix the position of the sliding plate. By continuing to press down the cover, the connecting post disengages from the groove of the outer wall of the irregular block, causing the second spring to rebound and drive the sliding plate to slide upward, thereby restoring the buckle to its original state and releasing the fixation of the second fixing block, thus realizing the rapid closing and opening of the cover.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 - Figure 3One embodiment of this utility model is a battery box that can install batteries of various specifications, including a box 2, and an installation component is provided inside the box 2. The mounting assembly includes a mounting plate 5, the lower surface of which is fixedly connected to the inside of the box 2. The mounting plate 5 is used to hold batteries 4 of different specifications. The upper surface of the mounting plate 5 has mounting holes 7. The batteries 4 are attached to the upper surface of the mounting plate 5. Fixing plates 6 are fixedly connected to both sides of the outer wall of the batteries 4. The upper surface of the fixing plate 6 is attached to the outer shell 10. The inner surface of the outer shell 10 is slidably connected to a fixing post 8. The lower end of the fixing post 8 is fixedly connected to a first fixing block 12. By pressing down and rotating the fixing post 8, the first fixing block 12 slides within the fixing plate 6 and the mounting holes 7, and rotates within the mounting holes 7. This prevents the first fixing block 12 from aligning with the mounting hole 7 on the mounting plate 5, thereby fixing the fixing plate 6. A limiting block 9 is fixedly connected to the outer wall of the fixing post 8. The limiting block 9 is used to limit the displacement distance of the fixing post 8. A first spring 11 is attached to the outer wall of the fixing post 8. The first spring 11 is used to make the fixing post 8 pop out quickly when the first fixing block 12 rotates to align with the mounting hole 7, thereby releasing the fixing post 8 from fixing the fixing plate 6. One end of the first spring 11 is fixedly connected to the inside of the outer shell 10, and the other end of the first spring 11 is fixedly connected to the outer wall of the limiting block 9.

[0020] Specifically, by placing the battery 4 on the mounting plate 5 inside the box 2, aligning the fixing plate 6 with the mounting hole 7, placing the outer casing 10 on the fixing plate 6, allowing the first fixing block 12 to pass through the fixing plate 6, and then pressing down the fixing post 8 to make the first fixing block 12 slide downwards in the mounting hole 7, while simultaneously compressing the first spring 11, and by rotating the fixing post 8, the first fixing block 12 rotates until it can no longer align with the mounting hole 7 opened on the upper surface of the mounting plate 5, thereby firmly fixing the fixing plate 6 to the upper surface of the mounting plate 5, thus realizing the installation of the battery 4. At the same time, this fixing method can also install batteries 4 of different specifications, solving the problem that traditional battery boxes can only install batteries 4 of a single specification and are difficult to cope with various usage scenarios.

[0021] Reference Figure 1 - Figure 5The box 2 has a sliding plate 15 slidably connected inside, and a buckle 14 is fixedly connected to the outer wall of the sliding plate 15. The buckle 14 is used to lock the second fixing block 13, thereby fixing the lid 1. A second spring 19 is provided on the lower surface of the sliding plate 15. One end of the second spring 19 is fixedly connected to the inside of the box 2, and the other end of the second spring 19 is fixedly connected to the lower surface of the sliding plate 15. The second spring 19 is used to enable the sliding plate 15 to quickly return to its original position when the buckle 14 releases the second fixing block 13. A handle 3 is rotatably connected to the outer wall of the box 2. An irregularly shaped block 17 is fixedly connected inside the box 2. 7 is used to slide the connecting post 18 along its surface, thereby fixing the position of the connecting post 18. The outer wall of the sliding plate 15 is rotatably connected to the connecting rod 16, and the outer wall of the connecting rod 16 is fixedly connected to the connecting post 18. The outer wall of the connecting post 18 is slidably connected to the outer wall of the irregular block 17. The outer wall of the box 2 is rotatably connected to the cover 1, and the outer wall of the cover 1 is fixedly connected to the second fixing block 13. The outer wall of the second fixing block 13 is attached to the inner wall of the buckle 14. The limiting block 9 is set inside the outer shell 10. The outer wall of the first fixing block 12 is rotatably connected to the inside of the mounting hole 7. The outer wall of the fixing post 8 is slidably connected to the inside of the fixing plate 6 and the mounting hole 7.

[0022] Specifically, by rotating and pressing down on the cover 1, the second fixing block 13 moves downward and fits against the outer wall of the buckle 14. By continuing to press down on the cover 1, the second fixing block 13 moves downward against the buckle 14, thereby driving the sliding plate 15 to slide downward. At this time, during the downward movement of the buckle 14, due to the narrowing of the internal space, the buckle 14 undergoes elastic deformation and moves inward, thereby firmly locking the second fixing block 13. By causing the sliding plate 15 to slide downward, the connecting post 18 slides into the groove on the outer wall of the irregular block 17, while compressing the second spring 19 to fix the position of the sliding plate 15. By continuing to press down on the cover 1, the connecting post 18 disengages from the groove on the outer wall of the irregular block 17, causing the second spring 19 to rebound and drive the sliding plate 15 to slide upward, thereby restoring the buckle 14 to its original state and releasing the fixation of the second fixing block 13, thus realizing the rapid closing and opening of the cover 1.

[0023] Working principle: When it is necessary to install battery 4 in the battery box, first place battery 4 on the mounting plate 5 set inside the box 2, then align the fixing plate 6 with the mounting hole 7, place the outer shell 10 on the fixing plate 6 so that the first fixing block 12 passes through the fixing plate 6, and then press down the fixing post 8 so that the first fixing block 12 slides downward in the mounting hole 7, while compressing the first spring 11. By rotating the fixing post 8, the first fixing block 12 rotates until it can no longer align with the mounting hole 7 opened on the upper surface of the mounting plate 5, so that the fixing post 8 firmly fixes the fixing plate 6 to the upper surface of the mounting plate 5, thereby realizing the installation of battery 4. At the same time, this fixing method can also install batteries 4 of different specifications, solving the problem that traditional battery boxes can only install batteries 4 of a single specification and are difficult to cope with various usage scenarios. By rotating and pressing down the cover 1, the second fixing block 13 moves downward and fits the buckle 14. By continuing to press the cover 1 downwards, the second fixing block 13 moves downwards against the buckle 14, thereby causing the sliding plate 15 to slide downwards. At this time, as the buckle 14 moves downwards, due to the narrowing of the internal space, the buckle 14 undergoes elastic deformation and moves inwards, thus firmly locking the second fixing block 13. By causing the sliding plate 15 to slide downwards, the connecting post 18 slides into the groove on the outer wall of the irregular block 17, while compressing the second spring 19 to fix the position of the sliding plate 15. By continuing to press the cover 1 downwards, the connecting post 18 disengages from the groove on the outer wall of the irregular block 17, causing the second spring 19 to rebound and drive the sliding plate 15 to slide upwards, thereby restoring the buckle 14 to its original state and releasing the fixation of the second fixing block 13, thus realizing the rapid closing and opening of the cover 1.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
