[0012] Compared with the prior art, this utility model provides a cabinet door made of aluminum laser-welded plate, which has the following beneficial effects:

[0013] The technical solution disclosed in this utility model achieves high strength and low deformation of the cabinet door through a laser welding structure of outer aluminum plate, inner aluminum plate and support frame. The weld is continuously sealed, providing excellent dustproof and waterproof performance. The grid-like support frame further enhances the overall compressive strength. The optimized design of aluminum plate thickness and spacing ensures lightweight while avoiding deformation caused by heat input during welding, thus improving welding quality.

[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] Figures 1-4 In one embodiment of this utility model, an aluminum laser-welded cabinet door includes a cabinet door body, which is composed of an outer aluminum plate 1, an inner aluminum plate 2, and a support frame 3 disposed between the two. The circumferential edges of the outer aluminum plate 1 and the inner aluminum plate 2 are laser-welded to form a continuous sealed weld, and the circumferential edges of the support frame 3 are laser-welded to the inner sides of the outer aluminum plate 1 and the inner aluminum plate 2. The support frame 3 includes transverse reinforcing ribs 31 and longitudinal reinforcing ribs 32, which intersect to form a grid structure.

[0022] The specific problem addressed in this embodiment is the lack of internal support structure in cabinet doors, resulting in low strength and compressive strength, while the overall weight of the cabinet door is large, leading to deformation during welding. This utility model achieves high strength and low deformation of the cabinet door through a laser-welded structure of outer aluminum plate 1, inner aluminum plate 2, and support frame 3. The weld seams are continuously sealed, providing excellent dust and water resistance. The grid-like support frame 3 further enhances the overall compressive strength. The optimized design of the aluminum plate thickness and spacing ensures lightweight construction while avoiding deformation caused by heat input during welding, thus improving welding quality. The hollow aluminum alloy profile support frame 3 reduces the overall weight, and the uniform distribution of transverse and longitudinal reinforcing ribs 31 and 32 enhances structural stability. Through the laser-welded structure of double-layer aluminum plates and the grid support frame, high-precision, high-strength cabinet door manufacturing is achieved, featuring lightweight, deformation resistance, and good sealing performance, making it suitable for both home and industrial cabinet applications.

[0023] The outer aluminum plate 1 and the inner aluminum plate 2 are both 0.8-1.5mm thick, and the distance between them is 5-10mm. In this specific embodiment, the support frame 3 is made of aluminum alloy profile, and its cross-section is a hollow rectangular structure. The transverse reinforcing ribs 31 and the longitudinal reinforcing ribs 32 are evenly distributed along the interior of the hollow rectangular structure. The number of transverse reinforcing ribs 31 and the number of longitudinal reinforcing ribs 32 are 3-5, and the size of the grid unit formed by the intersection is 50mm×50mm to 100mm×100mm. The cabinet door achieves high strength and low deformation through laser welding of the outer aluminum plate 1, inner aluminum plate 2, and support frame 3. The weld seams are continuously sealed, providing excellent dustproof and waterproof performance. The grid-like support frame 3 further enhances the overall compressive strength. The optimized design of the aluminum plate thickness and spacing ensures lightweight construction while avoiding deformation caused by heat input during welding, thus improving welding quality. The hollow aluminum alloy profile support frame 3 reduces the overall weight, and the uniform distribution of horizontal and vertical reinforcing ribs 31 and 32 enhances structural stability. Through the laser welding structure of the double-layer aluminum plate and grid support frame, high-precision and high-strength cabinet door manufacturing is achieved. It features lightweight construction, deformation resistance, and good sealing performance, making it suitable for home and industrial cabinet applications.

[0024] In this specific embodiment, the width of the continuous sealing weld is 0.5-1.2mm, and the weld shape is a continuous straight line or a wave shape. The continuous sealing weld of a specific width combined with the wave shape design can absorb the stress of thermal expansion and contraction and reduce the risk of weld cracking.

[0025] In this specific embodiment, the outer surface of the outer aluminum plate 1 is provided with a decorative layer 4, which is an oxide film layer or a spray coating layer. The decorative layer 4 improves the aesthetics and corrosion resistance of the cabinet door, extends its service life, and adapts to different decoration style requirements.

The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
