Description

Technical Field

[0001] This utility model relates to the field of aluminum box structure technology, and in particular to a stamped load-bearing waterproof aluminum box. Background Technology

[0002] In fields such as electronic equipment and precision instruments, aluminum boxes are often used to encapsulate and protect internal components. Traditional aluminum boxes have the following shortcomings: First, the thickness of the top plate of the outer shell is not reasonably designed, resulting in poor strength and easy deformation under load, which affects the protection of internal components; second, the connection structure between the outer shell and the bottom plate is simple, mostly consisting of direct splicing followed by simple welding or gluing, resulting in poor connection reliability and difficulty in ensuring waterproof sealing. Moisture can easily penetrate and damage internal components, so it is necessary to improve them. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a stamped load-bearing and waterproof aluminum box that enhances the strength of the outer shell, optimizes the connection structure between the outer shell and the base plate, improves the overall load-bearing and waterproof performance, and reliably protects the internal components.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a stamped load-bearing waterproof aluminum box, comprising a base plate and an outer shell, the outer shell being made of aluminum profile stamping, the outer shell being rectangular in shape, the bottom of the outer shell being hollowed out to form an assembly cavity, and the bottom edge of the outer shell being formed with an arc edge; the surface of the base plate is milled to form an assembly groove, the assembly groove including a first arc groove and a second arc groove, the first arc groove being located inside the second arc groove, and the two being intersected; during assembly, the arc edge of the outer shell is fixed to the first arc groove by adhesive, and the second arc groove is filled with a waterproof sealing ring structure composed of waterproof adhesive or solder, the waterproof sealing ring structure being connected to the outer side of the arc edge.

[0005] In a further technical solution, the radius of the first arc-shaped groove is 1.3mm-1.5mm; the radius of the second arc-shaped groove is 1.2mm-1.4mm, and the radius of the second arc-shaped groove is smaller than the radius of the first arc-shaped groove.

[0006] In a further technical solution, the thickness d of the top plate of the outer shell is 8mm-15mm; the thickness of the side wall of the outer shell is the same as the radius of the first arc groove.

[0007] In a further technical solution, the outer surface of the shell is formed with multiple reinforcing ribs, which extend along the length of the shell and are spaced apart along the width of the shell.

[0008] In a further technical solution, the width of the reinforcing rib is 1mm-1.5mm, the protrusion height of the reinforcing rib is 1.5mm-2mm, and the interval between two adjacent reinforcing ribs is 5mm-12mm.

[0009] In a further technical solution, the front side of the housing is provided with multiple lead wire holes; the front side of the bottom plate is formed with a lead wire support plate, which is provided with multiple external interfaces, each of which is aligned with the corresponding lead wire hole.

[0010] In a further technical solution, each external interface is snapped with a soft rubber connector. The inner end of the soft rubber connector is formed with a first limiting ring protruding outward, and the soft rubber connector near the inner side is formed with a second limiting ring protruding outward. A snap-fit ​​portion is formed between the first limiting ring and the second limiting ring. The soft rubber connector is snapped to the external interface through the snap-fit ​​portion. During assembly, the inner end face of the soft rubber connector abuts against the outer wall of the shell to form a waterproof lead wire structure.

[0011] In a further technical solution, the soft rubber connector has an internal through-hole for the lead wire, with a diameter of 5mm-10mm. The soft rubber connector is elastic, and the lead wire hole always elastically fits onto the outer sheath of the target lead wire.

[0012] The advantages of this invention compared to the prior art after adopting the above structure are:

[0013] 1. The assembly groove design, consisting of a first arc-shaped groove and a second arc-shaped groove, allows the outer shell's arc-shaped edge to be embedded in the first arc-shaped groove for adhesive fixation, while the second arc-shaped groove is filled with a waterproof sealing ring (waterproof adhesive / solder). This dual-structure design achieves precise positioning and a stable connection between the outer shell and the base plate, while also creating a multi-layered waterproof barrier to effectively prevent moisture intrusion. This design is suitable for harsh environments such as humid and water-related conditions, ensuring the long-term stable operation of internal components.

[0014] 2. The thickness of the top plate of the outer shell is much greater than that of traditional designs. Combined with reinforcing ribs that extend along the length direction and are spaced apart in the width direction, the load-bearing capacity of the outer shell is greatly improved, external pressure is distributed, and deformation of the top plate is prevented, which can effectively protect the internal precision components.

[0015] 3. The soft rubber connector is connected to the external interface by a snap-fit, and the inner end face abuts against the outer wall of the shell to form a physical seal; the elastic lead wire sleeve hole is adapted to the outer sheath of the target lead wire, tightly wraps to avoid gaps, cuts off the waterproof path from the point where the lead wire passes through, solves the problem of easy water leakage in traditional lead wire holes, and ensures the waterproofness of the lead wire interface.

The outer shell 2 is made of aluminum profile by stamping and is rectangular in shape. The bottom of the outer shell 2 is hollowed out to form an assembly cavity. The bottom edge of the outer shell 2 is formed with an arc edge 20. The surface of the base plate 1 is milled to form an assembly groove 13. The assembly groove 13 includes a first arc groove 131 and a second arc groove 132. The first arc groove 131 is located inside the second arc groove 132 and the two are intersecting. During assembly, the arc edge 20 of the outer shell 2 is fixed to the first arc groove 131 by adhesive. The second arc groove 132 is filled with a waterproof sealing ring structure composed of waterproof adhesive or solder. The waterproof sealing ring structure is connected to the outer side of the arc edge 20.

[0023] The assembly groove 13, composed of the first arc-shaped groove 131 and the second arc-shaped groove 132, allows the arc-shaped edge 20 of the outer shell 2 to be embedded in the first arc-shaped groove 131 for adhesive fixation. The second arc-shaped groove 132 is filled with a waterproof sealing ring and waterproof adhesive / solder. In this embodiment, a waterproof sealing ring composed of solder is used. This dual structure not only achieves precise positioning and stable connection between the outer shell 2 and the base plate 1, but also constructs a multi-layer waterproof barrier to effectively prevent moisture intrusion, making it suitable for harsh environments such as humid and water-related conditions, and ensuring the long-term stable operation of internal components.

[0025] Specifically, the thickness d of the top plate of the outer shell 2 is 10mm; the thickness of the side wall of the outer shell 2 is the same as the radius of the first arc groove 131. The thickness of the top plate of the outer shell 2 is much greater than that of the traditional design. Combined with the reinforcing ribs that extend along the length direction and are spaced apart in the width direction, the load-bearing capacity of the outer shell 2 is greatly improved, external pressure is distributed, and deformation of the top plate is prevented, which can effectively protect the internal precision components.

[0026] Specifically, the outer surface of the outer shell 2 is formed with a plurality of reinforcing ribs 21, which extend along the length of the outer shell 2 and are distributed at intervals along the width of the outer shell 2.

[0027] Specifically, the width of the reinforcing rib 21 is 1mm, the protrusion height of the reinforcing rib 21 is 1.5, and the interval between two adjacent reinforcing ribs 21 is 5mm.

[0028] Specifically, the front side of the outer casing 2 is provided with multiple lead wire holes 22; the front side of the bottom plate 1 is formed with a lead wire support plate 12, which is provided with multiple external interfaces 120, each external interface 120 being aligned with the corresponding lead wire hole 22.

[0029] Specifically, each external interface 120 is snapped with a soft rubber connector 3. The inner end of the soft rubber connector 3 is formed with a first limiting ring 31 protruding outward, and the soft rubber connector 3 is formed with a second limiting ring 32 protruding outward near the inner side. A snap-fit ​​part 33 is formed between the first limiting ring 31 and the second limiting ring 32. The soft rubber connector 3 is snapped to the external interface 120 through the snap-fit ​​part 33. During assembly, the inner end face of the soft rubber connector 3 abuts against the outer wall of the outer shell 2 to form a waterproof lead wire structure.

[0030] Specifically, the soft rubber connector 3 has an internal through-hole for the lead wire, which has a diameter of 5mm. The soft rubber connector 3 is elastic, and the lead wire hole is always elastically fitted onto the outer sheath of the target lead wire.

[0031] The soft rubber connector 3 is connected to the external interface by a snap-fit, and the inner end face abuts against the outer wall of the outer shell 2 to form a physical seal; the elastic lead wire sleeve hole is adapted to the outer sheath of the target lead wire, tightly wraps to avoid gaps, cuts off the waterproof path from the lead wire passage, solves the problem of easy water leakage in traditional lead wire holes, and ensures the waterproofness of the lead wire interface.
