[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] First embodiment

[0034] See also Figure 1-Figure 12 The integrated optimized drawer side panel and back panel assembly structure comprises a side panel and a back panel, wherein the side panel is made of a metal material and is provided with a planar side surface portion 1, and a rear connecting portion 2 is integrally bent at the rear end of the side surface portion 1; the back panel is made of a metal material and is provided with a planar back surface portion 3, and assembly portions 4 are integrally or separately provided at the left and right ends of the back surface portion 3, and a fastening portion 5 is integrally or separately provided on the assembly portion 4; the back panel is connected with the rear connecting portion 2 through the fastening portion 5 to realize the assembly of the side panel and the back panel.

[0035] The side panels and the back panel are respectively made of metal materials, and then a planar side portion 1 and a back portion 3 are respectively provided on the side panels and the back panel. The planar side portion 1 can avoid the problem of forming a cavity inside the side panel shell in the prior art, resulting in a reduced storage space inside the drawer. The planar back portion 3 can reduce the thickness of the back panel to avoid the problem of the back panel thickness being too large and occupying the storage space inside the drawer, thereby further increasing the storage capacity inside the drawer and allowing the user to store more objects. In addition, the planar side portion 1 and the back portion 3 can not only facilitate the transportation and storage of the side panels and the back panel, but also significantly reduce the manufacturing cost.

[0036] The back panel can be assembled on the side panel through the cooperation of the fastening part 5 and the rear connecting part 2, which effectively simplifies the assembly process of the side panel and the back panel, makes the assembly between the two faster, and improves the assembly efficiency; at the same time, the assembly between the side panel and the back panel is transferred and assembled through the assembly part 4, the fastening part 5, and the rear connecting part 2, and its assembly stability is high, thereby improving the service life of the drawer.

[0037] The back portion 3, the assembly portion 4, and the fastening portion 5 can be arranged in one piece or separately. A variety of different molding methods can effectively simplify the production process of the back panel, making the production of the back panel more convenient and reducing the production cost.

[0038] Specifically, the back portion 3 is a planar sheet metal part, and its front and / or rear side are basically vertical. In this embodiment, the front and rear sides of the back portion 3 are both vertical; the assembly portion 4 is integrally arranged toward the rear of the side panel or separately arranged at the left and right ends of the back portion 3, and the two are basically perpendicular to each other, and are at right angles, or chamfered, or arced, or a combination thereof.

[0039] The side portion 1 is a planar sheet metal part, and its inner side and / or outer side are basically vertical. In this embodiment, the inner side and outer side of the side portion 1 are both vertical; the rear connecting portion 2 is integrally bent on the inner side of the rear end of the back portion 3, and the two are basically perpendicular to each other, and are at right angles, or chamfered, or arced, or a combination thereof.

[0040] A shielding portion 6 is integrally bent above the back portion 3 toward the rear of the side panel. The shielding portion 6 is basically perpendicular to the back portion 3 and is transitioned to each other at right angles, or chamfers, or arcs, or a combination thereof. The top surface of the shielding portion 6 is basically flush with the top surface of the side portion 1 and / or the top surface of the rear connecting portion 2.

[0041] The back portion 3 is located in front of the rear connecting portion 2; the inner side of the side portion 1 and the outer end of the back portion 3 and / or the outer end of the shielding portion 6 rely on each other or fit with a gap; the rear end of the shielding portion 6 and the front side of the rear connecting portion 2 rely on each other or fit with a gap.

[0042] In this embodiment, the inner side of the side portion 1 is preferably mutually supported with the outer end of the back portion 3 and the outer end of the shielding portion 6, and the rear end of the shielding portion 6 is mutually supported with the front side of the rear connecting portion 2. Due to the mutual support between the above components, the gap between the back plate and the side plate after assembly can be effectively avoided, so as to improve the integrity of the drawer and make the assembly of the drawer more secure.

[0043] The assembly portion 4 and the fastening portion 5 are respectively located below the shielding portion 6 ; the side panel covers the assembly portion 4 and / or the fastening portion 5 through the cooperation of the side portion 1 , the rear connecting portion 2 , and the shielding portion 6 .

[0044] After being covered, the assembly part 4 and / or the fastening part 5 can be prevented from being exposed, thereby reducing a series of problems such as injuries caused by easy contact during daily use, damage to the assembly part 4 and / or the fastening part 5, or poor assembly stability of the drawer, thereby improving the user experience.

[0045] like Figure 5 , Figure 6 , Fig. 9 , Fig.10 As shown, the assembly part 4 is a separate component, and is separately provided with the left and right ends of the back part 3 and then fixed together by fasteners, snaps, welding, or bonding.

[0046] Or as Fig.11 , Fig.12 As shown, the assembly portion 4 is integrally formed at the left and right ends of the back portion 3 .

[0047] The above-mentioned assembly part 4 is provided with an adapter 7, which is separately provided with the assembly part 4, and the two are fixed together by fasteners, snaps, welding, or bonding; the fastening part 5 is provided on the adapter 7, and a fastener 8 is provided between the fastening part 5 and the rear connecting part 2, and the fastener 8 fastens between the fastening part 5 and the rear connecting part 2 to realize the fastening assembly of the side panel and the back panel.

[0048] The present structure also includes a drawer bottom plate 9; a front connecting portion 10 is integrally bent on the inner side of the front end of the side portion 1, and a drawer front panel 11 is connected through the front connecting portion 10, wherein the front connecting portion 10 and the inner side of the front end of the side portion 1 are substantially perpendicular to each other, and are at right angles, chamfered, circular, or a combination thereof.

[0049] The lower part of the side part 1 extends downward and is integrally or separately provided with a support part 12 , which is substantially perpendicular to the side part 1 and forms a right angle, a chamfer, an arc or a combination thereof.

[0050] A receiving portion 13 is integrally bent at the lower portion of the back portion 3 toward the front of the side plate. The receiving portion 13 and the back portion 3 are substantially perpendicular to each other and form a right angle, a chamfer, an arc, or a combination thereof.

[0051] The bottom of the drawer bottom plate 9 is respectively supported on the supporting portion 12 and the receiving portion 13 , and the rear end thereof and the front side of the back portion 3 are mutually supported or gap-fitted.

[0052] Since the drawer bottom plate 9 is directly supported on the supporting part 12 and the receiving part 13, more components can bear the force of the drawer bottom plate 9 when it is loaded. While ensuring the load capacity of the drawer, the thickness of the side panels and the back panel can be reduced, and the storage space inside the drawer can be further increased. Moreover, the force generated by the drawer bottom plate when loaded can be fully distributed on the supporting part 12 and the receiving part 13. Compared with the drawers in the prior art, the force is more evenly distributed and the working loss between the components is smaller, thereby extending the service life of the drawer.

[0053] Due to the perpendicularity, right angles, chamfers, arcs or their combined transitional relationships among the side portion 1, the rear connecting portion 2, the front connecting portion 10, the back portion 3, the shielding portion 6, the receiving portion 13 and the assembly portion 4, a square spatial layout can be formed inside the drawer after assembly, thereby improving the utilization rate and integrity of the space inside the drawer.
