Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery box technology, and in particular to an aluminum extruded box with an IP67 protection rating. Background Technology
[0002] With the development of battery enclosure technology, a technology has emerged that uses a top cover and an aluminum extruded enclosure to form a sealed cavity for installing batteries.
[0003] In related technologies, the aluminum extrusion box body and the top cover are usually connected by setting rivet nuts on the sealing surfaces to achieve a waterproof effect.
[0004] However, the above-mentioned battery box assembly method or related device has the following problems:
[0005] First, if the rivet nut is poorly manufactured, the aluminum extruded housing will not meet the IP67 protection requirements.
[0006] Second, existing battery box structures are mostly made of sheet metal or casting processes, which have poor protective performance, complex processing technology, and welding quality has a great impact on waterproof performance and high labor costs.
[0007] Third, the lack of efficient assembly methods for battery sealing design leads to low production efficiency. Utility Model Content
[0008] In response to the shortcomings of the existing production technology, the applicant provides an aluminum extrusion box with an IP67 protection rating, thereby achieving IP67 protection, simplifying the processing technology and improving assembly efficiency, and solving the problems of poor protection performance and inefficient assembly.
[0009] The technical solution adopted in this utility model is as follows: an aluminum extruded box with an IP67 protection rating, comprising:
[0010] The box body has a frame made of extruded aluminum profile. From top to bottom, the extruded aluminum profile has an upper flange, a middle flange, and a lower flange, with the distance between the middle flange and the lower flange being less than the distance between the middle flange and the upper flange. The upper flange, middle flange, and lower flange are parallel to the length of the extruded aluminum profile and have multiple process angles at bending points for bending the aluminum profile. A top cover is located at the top of the box body frame and forms a sealed fit with the upper flange. A bottom plate is located at the bottom of the box body frame and forms a sealed fit with the lower flange. Sealing rings are provided between the top cover and the upper flange, and between the bottom plate and the lower flange, to ensure the airtightness of the aluminum extruded box body.
[0011] As a further improvement to the above technical solution:
[0012] In one embodiment, the aluminum extruded profile sheet is bent at the process corner using a bending die, and then welded at the joint after bending to form a frame-like box frame.
[0013] In one embodiment, the upper and lower flanges are respectively provided with rivet nuts, which are used to assemble and fix the upper cover and the bottom plate to the middle frame of the box by bolts.
[0014] In one embodiment, the top cover is engaged with the rivet nut on the upper flange by screwing on, and the sealing ring on the upper flange is pressed to form a top sealing layer.
[0015] In one embodiment, the base plate engages with the rivet nut on the lower flange by screwing in screws, and compresses the sealing ring on the lower flange to form a bottom sealing layer.
[0016] In one embodiment, the inner frame, the top cover, and the bottom plate of the housing together constitute a sealed cavity of the aluminum extrusion housing, which is used to assemble electronic components.
[0017] The beneficial effects of this utility model are as follows:
[0018] This utility model has a compact structure. By using the flange structure and process angle bending of the aluminum extruded profile plate, the box structure is simplified, the number of parts is reduced, and the processing and assembly efficiency is improved.
[0019] This utility model also has the following advantages:
[0020] (1) This utility model has a high protection level. It adopts a sealing ring and a flange to ensure the airtightness of the box and meet the IP67 protection requirements, effectively preventing moisture and dust from entering.
[0021] (2) This utility model is easy to assemble. The rivet nuts set on the upper and lower flanges facilitate the bolt assembly of the upper cover and the bottom plate, reducing the assembly difficulty and labor cost. Attached Figure Description

[0036] like Figures 1-6 The accompanying drawing shows a structural diagram of an aluminum extruded box with an IP67 protection rating according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.
[0037] In this embodiment, an aluminum extruded enclosure with an IP67 protection rating is provided, including an inner frame 1, an upper cover 4, and a bottom plate 5.
[0038] In this embodiment, the inner frame 1 of the box is made of aluminum extruded profile plate, and the aluminum extruded profile plate is provided with an upper flange 102, a middle flange 104 and a lower flange 103 from top to bottom.
[0039] Furthermore, the distance between the middle flange 104 and the lower flange 103 is smaller than the distance between the middle flange 104 and the upper flange 102, thus not only strengthening the structure but also preventing mistakes during the production process.
[0040] In this embodiment, the upper flange 102, the middle flange 104, and the lower flange 103 are all arranged parallel to the length direction of the aluminum extruded profile sheet. At the same time, multiple process angles 101 are provided at the bending positions, which are used for bending operations of the aluminum extruded profile sheet.
[0041] In the specific production process, the aluminum extruded profile sheet is bent at the process corner 101 by the bending die 2, and then welded at the splice 105 after bending, thereby forming the box-shaped inner frame 1.
[0042] In this embodiment, the top cover 4 is located on the top of the inner frame 1 of the box and forms a sealing fit with the upper flange 102; in order to ensure the sealing performance, a sealing ring 3 is provided between the top cover 4 and the upper flange 102.
[0043] In this embodiment, the bottom plate 5 is set at the bottom of the inner frame 1 of the box and forms a sealing fit with the lower flange 103, and a sealing ring 3 is also provided between the bottom plate 5 and the lower flange 103.
[0044] Furthermore, rivet nuts 106 are respectively provided on the upper flange 102 and the lower flange 103. These rivet nuts 106 are used to fix the upper cover 4 and the bottom plate 5 to the middle frame 1 of the box body by bolt assembly.
[0045] Specifically, the top cover 4 engages with the rivet nut 106 on the upper flange 102 by screwing in the screws, and presses the sealing ring 3 on the upper flange 102 to form a top sealing layer;
[0046] Similarly, the base plate 5 engages with the rivet nut 106 on the lower flange 103 by screwing in screws, and presses the sealing ring 3 on the lower flange 103 to form a bottom sealing layer.
[0047] In summary, this utility model has a reasonable structure and simple assembly operation. The inner frame 1, the upper cover 4, and the bottom plate 5 together constitute the sealed cavity of the aluminum extrusion box, which can be used to assemble electronic components (such as batteries). The aluminum extrusion box of this utility model has a compact structure, is easy to assemble, and has a high protection level, meeting the IP67 protection requirements, effectively preventing moisture and dust intrusion, and has broad application prospects.
[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0049] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent.
