Description

Technical Field

[0001] This utility model specifically relates to a high-voltage battery box. Background Technology

[0002] Existing battery boxes consist of a box body and multiple lithium battery modules and other internal components housed within the box. Each lithium battery module includes multiple lithium-ion batteries. These modules and other internal components are installed within the box according to predetermined areas. However, these boxes typically define approximate installation areas and then install components by workers, such as installing components in the front, back, left, and right areas of the box body. There is a lack of a clear installation structure defining the installation of different components, making it impossible to clearly distinguish the installation areas and causing inconvenience during installation. Furthermore, the existing battery box structure is generally composed of six sheet metal panels, which increases the complexity of categorizing and storing different sizes of panels. During assembly, workers are prone to misassembly due to subtle differences in panel dimensions, failing to meet production requirements. Utility Model Content

[0003] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a high-voltage battery box.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A high-voltage battery box includes a box body, which includes a first L-shaped cover plate, a second L-shaped cover plate, and a U-shaped base plate that are spliced ​​together. The first L-shaped cover plate and the second L-shaped cover plate are respectively distributed and cover both ends of the U-shaped base plate. The length of the first L-shaped cover plate is greater than the length of the second L-shaped cover plate. A supporting partition is detachably connected between the first L-shaped cover plate and the U-shaped base plate. The supporting partition plate, the first L-shaped cover plate, and the U-shaped base plate enclose a battery cavity for installing and placing batteries. A wire-passing hole is formed between the supporting partition plate and the inner side of the U-shaped base plate. A plurality of mounting holes are spaced through one side of the second L-shaped cover plate. The first L-shaped cover plate has a first limiting flange at one end that can abut against the lower side of the second L-shaped cover plate, and the second L-shaped cover plate has a second limiting flange at one end that can abut against the lower side of the first L-shaped cover plate.

[0006] In one embodiment, the first L-shaped cover plate has a first flange on each side that can abut against the inner side of the U-shaped base plate, and the first flange is detachably connected to the U-shaped base plate by screws.

[0007] In one embodiment, the second L-shaped cover plate has a second flange on each side that can abut against the inner side of the U-shaped base plate, and the second flange is detachably connected to the U-shaped base plate by screws.

[0008] In one embodiment, the first limiting flange and the second L-shaped cover plate are detachably connected by screws.

[0009] In one embodiment, the support partition is disposed at one end of the first L-shaped cover plate adjacent to the second L-shaped cover plate.

[0010] In one embodiment, each end of the U-shaped base plate is provided with a third flange, and the third flange is detachably connected to the first L-shaped cover plate and the second L-shaped cover plate by screws.

[0011] In one embodiment, a mounting groove is recessed on one side of the first L-shaped cover plate or the second L-shaped cover plate, and a through hole is passed through the mounting groove. A desiccant container is disposed in the mounting groove, and a plurality of mesh holes are provided on the desiccant container at intervals. The desiccant container has an open cavity at the top, and a limiting post protrudes outward at one end of the desiccant container. A retaining groove is recessed on the periphery of the limiting post. A locking member is provided in the inner cavity of the box that can elastically extend and retract relative to it and abut against the retaining groove.

[0012] In one embodiment, the locking member includes a movable rod that is movably disposed within the inner cavity of the housing. A spring is sleeved on the movable rod, and the spring abuts against the movable rod and the inner side of the housing. The spring causes one end of the movable rod to remain inserted in the slot, while the other end of the movable rod passes through the outer side of the housing and protrudes to the outside of the housing.

[0013] In one embodiment, a handle is attached to one side of the third flange.

[0014] In one embodiment, a support plate abuts against the third flange and the U-shaped base plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model forms a box body by splicing together a first L-shaped cover plate, a second L-shaped cover plate, and a U-shaped bottom plate. A support partition is set between the first L-shaped cover plate and the U-shaped bottom plate. The support partition effectively improves the structural stability between the first L-shaped cover plate and the U-shaped bottom plate, while clearly dividing the internal cavity of the box. The support partition, the first L-shaped cover plate, and the U-shaped bottom plate enclose the battery cavity, while other internal components are installed in the area of ​​the second L-shaped cover plate through several mounting holes.

[0017] Furthermore, by using the first limiting flange at one end of the first L-shaped cover plate and the second limiting flange at one end of the second L-shaped cover plate, the first L-shaped cover plate and the second L-shaped cover plate form an interlocking installation structure, thereby achieving mutual foolproof installation between the first L-shaped cover plate and the second L-shaped cover plate while effectively enhancing the structural stability of the connection between the first L-shaped cover plate and the second L-shaped cover plate.

[0018] Furthermore, the enclosure is composed of only three types of panels: the first L-shaped cover, the second L-shaped cover, and the U-shaped base plate. This effectively reduces the need for inventory specification classification while ensuring that the shapes and appearances of the three types of panels are clearly distinguishable. In addition, the length of the first L-shaped cover is greater than that of the second L-shaped cover, and there is a clear dimensional distinction between the two. This makes it easier for installation workers to directly identify and install the enclosure, avoiding the drawbacks of installation workers taking the wrong enclosure and installing it incorrectly.

[0019] Furthermore, the desiccant container and locking mechanism work together to allow for quick installation and removal of the desiccant container. The opening on the cavity of the desiccant container fits snugly against the top wall of the installation groove, forming a cover for the desiccant container. After the desiccant container is removed, the operator can directly replace the desiccant inside through the opening on the cavity, avoiding the need for additional operation to open and close the desiccant container cover.

[0025] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0026] like Figures 1 to 5A high-voltage battery box is shown, comprising a box body 1. The box body 1 includes a first L-shaped cover plate 2 and a second L-shaped cover plate 3 and a U-shaped base plate 4 spliced ​​together. The first L-shaped cover plate 2 and the second L-shaped cover plate 3 are respectively distributed and cover both ends of the U-shaped base plate 4. The length of the first L-shaped cover plate 2 is greater than the length of the second L-shaped cover plate 3. A support partition 5 is detachably connected between the first L-shaped cover plate 2 and the U-shaped base plate 4. The support partition 5, the first L-shaped cover plate 2 and the U-shaped base plate 4 enclose a battery cavity 6 for installing and placing batteries. A wire-passing hole is formed between the support partition 5 and the inner side of the U-shaped base plate 4. A plurality of mounting holes 7 are spaced through one side of the second L-shaped cover plate 3. The first L-shaped cover plate 2 has a first limiting flange 8 at one end that can abut against the lower side of the second L-shaped cover plate 3, and the second L-shaped cover plate 3 has a second limiting flange 9 at one end that can abut against the lower side of the first L-shaped cover plate 2.

[0027] Specifically, the housing is formed by splicing the first L-shaped cover plate, the second L-shaped cover plate, and the U-shaped bottom plate together. A support partition is set between the first L-shaped cover plate and the U-shaped bottom plate. The support partition effectively improves the structural stability between the first L-shaped cover plate and the U-shaped bottom plate, while clearly dividing the internal cavity of the housing. The support partition, the first L-shaped cover plate, and the U-shaped bottom plate enclose the battery cavity, while other internal components are installed in the area of ​​the second L-shaped cover plate through several mounting holes.

[0028] Furthermore, by using the first limiting flange at one end of the first L-shaped cover plate and the second limiting flange at one end of the second L-shaped cover plate, the first L-shaped cover plate and the second L-shaped cover plate form an interlocking installation structure, thereby achieving mutual foolproof installation between the first L-shaped cover plate and the second L-shaped cover plate while effectively enhancing the structural stability of the connection between the first L-shaped cover plate and the second L-shaped cover plate.

[0029] Furthermore, the enclosure is composed of only three types of panels: the first L-shaped cover, the second L-shaped cover, and the U-shaped base plate. This effectively reduces the need for inventory specification classification while clearly distinguishing the shapes of the three types of panels. The first L-shaped cover is longer than the second L-shaped cover, and there is a clear dimensional difference between the two. This makes it easier for installation workers to directly identify and install the wrong parts, avoiding the drawbacks of installation workers taking the wrong parts and installing them incorrectly.

[0030] Furthermore, each side of the first L-shaped cover plate 2 is provided with a first flange 10 that can abut against the inner side of the U-shaped base plate 4, and the first flange 10 and the U-shaped base plate 4 are detachably connected by screws. This achieves a detachable connection between the first L-shaped cover plate and the U-shaped base plate, while the screw connection ensures a tight fit between the two, increasing structural robustness.

[0031] Furthermore, each side of the second L-shaped cover plate 3 is provided with a second flange 11 that can abut against the inner side of the U-shaped base plate 4, and the second flange 11 and the U-shaped base plate 4 are detachably connected by screws. This achieves a detachable connection between the second L-shaped cover plate and the U-shaped base plate, while the screw connection ensures a tight fit between the two, increasing structural robustness.

[0032] Furthermore, the first limiting flange 8 and the second L-shaped cover plate 3 are detachably connected by screws. This achieves a detachable connection between the first and second L-shaped cover plates while the screw connection ensures a tight fit between them, increasing structural robustness.

[0033] Furthermore, the supporting partition 5 is disposed at one end of the first L-shaped cover plate 2 adjacent to the second L-shaped cover plate 3.

[0034] Furthermore, each end of the U-shaped base plate 4 is provided with a third flange 12, which is detachably connected to the first L-shaped cover plate 2 and the second L-shaped cover plate 3 by screws. This achieves detachable connection between the U-shaped base plate and the first L-shaped cover plate and the second L-shaped cover plate, while the screw connection ensures a tight fit between the two connected parts, increasing structural robustness.

[0035] Furthermore, a mounting groove 13 is recessed on one side of the first L-shaped cover plate 2 or the second L-shaped cover plate 3. A through hole 14 is passed through the mounting groove 13. A desiccant container 15 is disposed in the mounting groove 13. A plurality of mesh holes 16 are provided on the desiccant container 15. The desiccant container 15 has an open cavity at the top. A limiting post 17 protrudes outward at one end of the desiccant container 15. A retaining groove 18 is recessed on the periphery of the limiting post 17. A locking member 19 is provided in the inner cavity of the box body 1, which can elastically extend and retract relative to it and abut against the retaining groove 18.

[0036] Specifically, the desiccant container and locking mechanism work together to allow for quick installation and removal of the desiccant container. The opening on the cavity of the desiccant container fits snugly against the top wall of the installation groove, forming a cover for the desiccant container. After the desiccant container is removed, the operator can directly replace the desiccant inside through the opening on the cavity, avoiding the need for additional operation to open and close the desiccant container cover.

[0037] Furthermore, the locking member 19 includes a movable rod 20 that is movably disposed within the inner cavity of the housing 1. A spring 21 is sleeved on the movable rod 20, and the spring 21 abuts against the movable rod 20 and the inner side of the housing 1. The spring 21 keeps one end of the movable rod 20 inserted into the slot 18, while the other end of the movable rod 20 protrudes outside the housing 1. In the initial state, the movable rod is held in place by the elastic force of the spring, with one end inserted into the desiccant container slot. When disassembly is required, the operator only needs to press the end of the movable rod protruding outside the housing to displace it from the slot, thus allowing the desiccant container to be removed from the opening of the mounting slot. Conversely, when reinstalling the desiccant container, the movable rod must be pressed before installation.

[0038] Furthermore, a handle 22 is connected to one side of the third flange 12. Furthermore, a support plate 23 abuts against the third flange 12 and the U-shaped base plate 4. The support plate increases the structural strength of the third flange relative to the U-shaped base plate, and the pulling force when the handle is lifted acts on the third flange of the U-shaped base plate, preventing stress deformation and damage to the first L-shaped cover plate and the second L-shaped cover plate.

[0039] Based on the accompanying drawings and the foregoing display and description of the basic principles, main features, and advantages of this utility model, those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
