[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described below in conjunction with the accompanying drawings and embodiments.

[0028] In related technologies, corner protectors are made of plastic through injection molding. Plastic corner protectors are not strong enough and are not wear-resistant. To improve their strength, the size is usually increased. However, the increased overall volume can easily form protrusions on the outer surface of stainless steel parts, making the stainless steel parts less aesthetically pleasing.

[0029] To address the aforementioned issues, this application provides a corner protector strip and a coated plate. The corner protector strip is made of metal, which reduces its overall volume while ensuring the structural strength of the corner protector strip, thereby ensuring a more aesthetically pleasing outer surface of the stainless steel plate.

[0030] See Figure 1 Figure 2 ,as well as Figure 5 and Figure 6 As shown, the corner protector 100 provided in this embodiment includes an exposed metal portion 10 and a metal insertion portion 20. The exposed metal portion 10 and the metal insertion portion 20 are integrally formed, for example by die casting. The material can be stainless steel or other materials. Under the premise of ensuring the structural strength of the corner protector 100, compared with the corner protectors made of plastic materials in related technologies, which need to increase the volume to improve the structural strength, the method of using metal materials provided in this application can significantly reduce the overall volume of the corner protector 100.

[0031] The corner protector 100 provided in this application is used to insert into the slots at the corners of the coated panel, wherein, see Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9As shown, the coated plate includes a bottom shell 200, a filler 300, and a top cover 400. The bottom shell 200 has a bottom plate 201 and at least three side plates 202 surrounding the bottom plate 201. The at least three side plates 202 and the bottom plate 201 form a mounting cavity 203. There is a corner 204 between two adjacent side plates 202. A slot 205 is formed at the corner 204 between two adjacent side plates 202. The filler 300 is disposed in the mounting cavity 203. The filler 300 is made of honeycomb aluminum. The top cover 400 is installed at the cavity opening 2031 of the mounting cavity 203 to close the mounting cavity 203.

[0032] In a specific embodiment, the bottom shell 200 is formed from a single piece of stainless steel sheet by laser cutting into a bottom plate 201 and at least three side plates 202. The at least three side plates 202 are bent upwards, creating corners 204 between adjacent side plates 202. Slots 205 are formed at the corners 204 where adjacent side plates 202 are located. The metal insert 20 of the corner protector 100 can be inserted into the slots 205, while the exposed metal part 10 is exposed outside the slots 205. In a preferred embodiment, the outer surface of the exposed metal part 10 is flush with the outer surface of the side plate 202. The outer surface of the exposed metal part 10 refers to the side of the exposed metal part 10 facing away from the metal insert 20. The adjacent side plates 202 can provide a clamping force to position the metal insert 20, preventing it from dislodging from the slots 205.

[0033] In the above embodiments, the corner protector 100, which is composed of a metal exposed part 10 and a metal insertion part 20 made of metal material, can improve the overall structural strength of the corner protector 100. Under the premise of ensuring structural strength, the overall volume of the corner protector 100 can be reduced, so that it can perfectly fit the outer surface of the base plate 200 after being inserted into the slot 205, thereby improving the overall aesthetics of the product.

[0034] The corner protector 100 provided in this application can be a straight structure or an L-shaped structure. The following embodiments illustrate corner protectors 100 of different shapes.

[0035] Regarding the corner protector with a straight structure 100

[0036] See Figure 1 and Figure 2 As shown, the metal insertion part 20 has two abutment tops 21. The abutment tops 21 are provided on both sides of the connection between the exposed metal part 10 and the metal insertion part 20. The two abutment tops 21 are formed on the metal insertion part 20. The two abutment tops 21 are used to abut against the two side walls of the slot 205 respectively, and cooperate with the two side walls of the slot 205 to limit the metal insertion part 20.

[0037] The corners between two adjacent side plates 202 are approximately V-shaped or L-shaped, which is not suitable for this shape. In this embodiment, the cross-sectional shape of the metal insertion part 20 is set to be V-shaped or L-shaped to improve the smoothness of the metal insertion part 20 being inserted into the slot 205 and to ensure the stability of the slot 205 in limiting its position.

[0038] See Figure 3 and Figure 4 As shown, slot 205 is a straight slot, and the corner guard 100 inserts the metal insertion part 20 into slot 205 from top to bottom along the length direction of slot 205.

[0039] Regarding L-shaped corner protectors 100

[0040] See Figure 5 and Figure 6 As shown, the exposed metal portion 10 has a main body portion 11 and a limiting portion 12, wherein the main body portion 11 and the limiting portion 12 are integrally formed and combined. Figure 7 and Figure 8 As shown, the limiting part 12 is located at the end of the exposed metal part 10 along the insertion direction. The limiting part 12 is used to cooperate with the outer wall of the slot 205 to limit the displacement of the metal insertion part 20 during insertion.

[0041] See Figures 7-9 As shown, the base plate 200 also includes bent side plates 206, wherein the side plates 202 are arranged vertically, and at least three side plates 202, the bent side plates 206, and the base plate 201 form a mounting cavity 203. Two adjacent side plates 202 are located at both ends of the bent side plate 206 along its length. The adjacent ends of the side plates 202 and the bent side plates 206 are formed into a bent shape adapted to the bent side plate 206, thus forming a bent corner 204 between the side plates 202 and the bent side plates 206, and a bent slot 205 is formed at the bent corner 204. The main body 11 has a bent shape, and the shape of the metal insertion part 20 is adapted to the shape of the main body 11. During the insertion of the bent metal insertion part 20, the limiting part 12 can limit the displacement of the inserted metal insertion part 20.

[0042] To ensure the consistency of the structure of the exposed metal portion 10 in the L-shaped corner protector 100, the width of the main body portion 11 is set to be the same as the width of the limiting portion 12.

[0043] See also Figure 5 and Figure 6As shown, the bent-shaped slots 205 are on the left and right sides of the product. In order to ensure that the corner guards inserted into the bent-shaped slots 205 are flush with the side plates 202 on the left and right sides of the base plate 100, the exposed metal part 10 is flush with the same side of the metal insertion part 20 along the width direction of the corner guard 100. Thus, two structural forms of the bent-shaped slots 205 corresponding to the left and right sides are formed respectively.

[0044] In the above embodiments, to ensure the stability of the L-shaped corner protector 100 inserted into the slot 205, please refer to... Figure 5 and Figure 6 As shown, the metal insertion part 20 adopts a plate shape, which can increase the contact area with the side wall of the slot 205 and improve the firmness of insertion and fixation.

[0045] In this application, since the laminated board is used in furniture, to improve safety, the edges of the exposed metal part 10 are rounded to avoid scratches to the user.

[0046] After inserting the corner protector 100 into the slot 205, to prevent the exposed metal part 10 from extending beyond the slot 205 and entering the interior, see [reference needed]. Figure 2 and Figure 6 As shown, in this embodiment, the width L1 of the exposed metal portion 10 is greater than the width L2 of the inserted metal portion 20.

[0047] Because the slot 205 has a very small width, the width L of the exposed metal portion 10 is set to 1mm-2mm to accommodate this width. In a preferred embodiment, the width of the exposed metal portion 10 is 1.5mm, which allows the two sides of the exposed metal portion 10 in the width direction to transition tightly with the side plates 202 on both sides, avoiding gaps, protrusions, etc., and ensuring the aesthetics of the overall structure of the laminated panel.

[0048] See Figure 9 As shown, the coated panel provided in this application includes the corner guard strip 100 in the above embodiment, and also includes a bottom shell 200, a filler 300 and a top cover 400. The bottom shell 200 has a bottom plate 201 and at least three side plates 202 surrounding the bottom plate 201. The at least three side plates 202 and the bottom plate 201 form a mounting cavity 203. There is a corner 204 between two adjacent side plates 202. A slot 205 is formed at the corner 204 between two adjacent side plates 202. The filler 300 is disposed in the mounting cavity 203. The filler 300 is made of honeycomb aluminum. The top cover 400 is installed at the cavity opening 2031 of the mounting cavity 203 to close the mounting cavity 203.

[0049] In a specific embodiment, the bottom shell 200 is formed from a single piece of stainless steel sheet by laser cutting into a bottom plate 201 and at least three side plates 202. The at least three side plates 202 are bent upwards, creating corners 204 between adjacent side plates 202. Slots 205 are formed at the corners 204 where adjacent side plates 202 are located. The metal insert 20 of the corner protector 100 can be inserted into the slots 205, while the exposed metal part 10 is exposed outside the slots 205. In a preferred embodiment, the outer surface of the exposed metal part 10 is flush with the outer surface of the side plate 202. The outer surface of the exposed metal part 10 refers to the side of the exposed metal part 10 facing away from the metal insert 20. The adjacent side plates 202 can provide a clamping force to position the metal insert 20, preventing it from dislodging from the slots 205.

[0050] In summary, the corner protector strip and the film-coated plate provided by this utility model, which are made of metal and consist of an exposed metal part and a metal insertion part, can improve the overall structural strength of the corner protector strip. While ensuring structural strength, the overall volume of the corner protector strip can be reduced, so that it can fit perfectly with the outer surface of the base plate after being inserted into the slot, thereby improving the overall aesthetics of the product.
