[0026] In one embodiment of this utility model, such as Figure 1-5As shown, an arc-shaped bent door includes a frame strip 1, a back panel 2, and a decorative panel 3. The frame strip 1 is bent to form a frame door 4. The back panel 2 is installed on the back of the frame door 4, and the decorative panel 3 is installed on the front of the frame door 4. The frame strip 1 includes a first frame 11, a second frame 12, a third frame 13, and a fourth frame 14. The first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 are integrally formed. The first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 are connected end to end in sequence. At each pair of the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14, the corners are bent to form a first rounded corner 15 and a second rounded corner 16. The first rounded corner 15 faces the outside of the frame door 4, and the second rounded corner 16 faces the inside of the frame door 4. The four corners of the back panel 2 are bent to form a third rounded corner 21. In this embodiment, the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 are integrally formed, meaning the frame door 4 is formed by bending a long strip of frame 1. The first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 have the same structure. The length of the four frame strips is designed according to customer needs. During manufacturing, after the long strip of frame 1 is formed, the excess frame material at the bending point is cut off. Then, the back panel 2 is placed on the back of the long strip of frame 1. Then, a bending device is used to simultaneously bend the long strip of frame 1 and the back panel 2 together, thereby bending the long strip of frame 1 into the first frame 11, the second frame 12, the third frame 13, and the fourth frame of the frame door 4. Furthermore, the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 are simultaneously bent at each pair of bending points, forming a first rounded corner 15 and a second rounded corner 16, respectively. The four corners of the back panel 2 are also simultaneously bent into third rounded corners 21. To enhance the connection stability of the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14, glue needs to be applied to the bending joints, and screws are used to lock and fix the back panel 2 to the back of the frame door 4. Finally, the decorative panel 3 is installed on the front of the frame door 4. The first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 of the frame door 4 described in this application are integrally bent and formed by a long strip frame 1, and the first rounded corner 15, the second rounded corner 16, and the third rounded corner 21 are formed simultaneously with the back panel 2 during the bending process. This not only makes the processing convenient and quick, which is conducive to improving production efficiency, but also eliminates the need for additional treatment of sharp corners during the production process, ensuring high safety. Furthermore, it can also avoid paint peeling and the need for secondary paint touch-up during the subsequent sanding and sharp corner removal process, which is conducive to improving the production quality of the product.

A mounting groove 1132 is formed between the baffle 1131 and the main body 111, and the mounting groove 1132 is used to install the decorative panel 3. In this embodiment, the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 have the same structure. The limiting plate 112 is vertically connected to the back of the main body 111. The back panel mounting area is formed by the four limiting plates 112 corresponding to the four frames, which facilitates the limiting of the back panel 2. One end of the protrusion 113 is connected to the front of the main body 111, and the other end of the protrusion 113 is provided with a baffle 1131. An installation groove 1132 is formed between the baffle 1131 and the main body 111. The decorative panel mounting area is formed by the four installation grooves 1132 corresponding to the four frames, which facilitates the limiting and installation of the decorative panel. The baffle 1131 makes it difficult for the decorative panel 3 to fall off, and plays a blocking and anti-detachment role.

[0028] like Figure 5 As shown, the mounting groove 1132 is provided with a first groove 1133. In this embodiment, the first groove 1133 is further recessed and formed on the inner side of the mounting groove 1132. By providing the first groove 1133, the stress of the protrusion 113 can be reduced, making it easier to process. Moreover, it can also prevent bending deformation during processing, which is beneficial to improving the production quality of the product.

[0029] like Figure 5 As shown, the back of the main body 111 is provided with a recessed portion 114, which is directly opposite the protruding portion 113, and the recessed portion 114 is provided with a first inclined surface 1141. In this embodiment, the recessed portion 114 is formed recessed from the back of the main body 111 towards the front, the recessed portion 114 is directly opposite the protruding portion 113, and the recessed portion 114 is provided with a first inclined surface 1141, thereby further reducing the stress on the protruding portion 113, facilitating processing, and avoiding bending deformation during processing, which is beneficial to improving the production quality of the product.

[0030] like Figure 5 As shown, a second inclined surface 1134 is provided on the outer side of the protrusion 113. In this embodiment, the second inclined surface 1134 is provided on the outer side of the protrusion 113, which not only reduces the sharp corner structure and improves safety, but also makes the arc-shaped bending door more aesthetically pleasing.

[0031] like Figure 5 As shown, a fourth rounded corner 1135 is provided at the connection between the second inclined surface 1134 and the baffle 1131. In this embodiment, the fourth rounded corner 1135 is provided at the connection between the second inclined surface 1134 and the baffle 1131. The use of a rounded transition structure can not only avoid scratches and abrasions, but also make the product more aesthetically pleasing.

[0032] like Figure 5 As shown, the inner side of the baffle 1131 is provided with a fifth rounded corner 1136. In this embodiment, the fifth rounded corner 1136 is provided on the inner side of the baffle 1131, and an arc structure is used instead of a right angle structure, so as to avoid the decorative panel 3 from being stuck in the mounting groove 1132.

[0033] like Figure 5 As shown, the back of the main body 111 is provided with a second groove 115, and the middle of the second groove 115 is provided with a positioning groove 1151. In this embodiment, the back of the main body 111 is recessed in the direction facing the front to form the second groove 115. The recessed design of the second groove 115 is used to embed the head of the locking screw, so as to avoid the head of the locking screw protruding and pressing against the back plate 2, which would cause the back plate 2 to be placed unevenly. The positioning groove 1151 facilitates the positioning and locking of the end of the locking screw.
