One end of the elastic structure 530 is connected to the rotating member 510, and the other end of the elastic structure 530 is connected to the cabinet body 200.

[0037] Among them, during the process of the door 100 opening or closing relative to the cabinet body 200, the rotating member 510 rotates to drive the elastic structure 530 to deform, and drives the connecting rod structure 520 to act accordingly. The connecting rod structure 520 drives the second sliding member 420 to move, so as to pull the door panel 300 to move in the width direction of the door 100.

[0038] According to the door assembly of the embodiment of the present invention, by providing a sliding door mechanism 400 and a traction mechanism 500, when the door 100 rotates relative to the cabinet body 200 to open or close, the connecting rod structure 520 and the elastic structure 530 act accordingly. The connecting rod structure 520 drives the second sliding member 420 to move. The second sliding member 420 slides relative to the first sliding member 410. The second sliding member 420 pulls the door panel 300 to move in the width direction of the door 100, so that the door panel 300 can slide during opening and closing to avoid interference with the side wall of the cabinet, and the elastic structure 530 can provide additional elastic support, improving the user experience.

[0039] It can be understood that, with reference to Figure 1 , according to an embodiment of the present utility model, the elastic structure 530 includes an elastic member 531. One end of the elastic member 531 is connected to the box body 200, and the other end of the elastic member 531 is connected to the rotating member 510. With the above structure, the elastic characteristics of the elastic member 531 can provide additional elastic support, making the opening and closing of the box door 100 smoother and reducing the impact on the rotating member 510 and the box body 200; the function of the elastic member 531 can also reduce the direct impact and stress received by the rotating member 510 and the box body 200, which helps to extend the service life of the components and is beneficial to improving stability.

[0040] It should be noted that in the embodiment of the present utility model, through the setting of the elastic structure 530 above, when the box door 100 is opened, the door panel 300 acts through the rotating member 510 and the elastic structure 530, which can prevent the door panel 300 from moving too fast relative to the box door 100, and the door panel 300 moves smoothly in the width direction relative to the box door 100; when the box door 100 is closed, the elastic structure 530 helps the rotating member 510 to reset, so that the rotating member 510 drives the link structure 520 to act, and the link structure 520 drives the second sliding member 420 to move relative to the first sliding member 410, thereby realizing the return of the door panel 300, which is beneficial to driving the door panel 300 to move to the initial position and plays a role in assisting.

[0041] It should be noted that, with reference to Figure 1 , in the embodiment of the present utility model, there are two elastic members 531, and the two elastic members 531 are arranged at intervals. With the above structure, the two elastic members 531 respectively bear part of the load, can provide sufficient force to drive the rotating member 510 to rotate, extend its service life, and make the relative movement between the door panel 300 and the box door 100 smoother. Of course, in some embodiments, the above elastic member 531 can also be one, three, etc., which are not limited here.

[0042] It can be understood that, with reference to Figure 1 , according to an embodiment of the present utility model, the traction mechanism 500 further includes a support plate 540. The support plate 540 is installed on the box body 200, and a support column 541 is provided on the support plate 540. The support column 541 is connected to the elastic member 531 in one-to-one correspondence. With the above structure, the elastic member 531 is fixedly matched with the support column 541, and the support plate 540 is installed on the box body 200 to achieve the installation. During the assembly process, the support plate 540 plays a supporting role and can further stabilize the position of the elastic member 531; at the same time, the design of the support plate 540 can simplify the overall assembly process.

[0043] Of course, in some embodiments, the above elastic member 531 can also be directly connected to the box door 100.

[0044] It should be noted that in the embodiment of the present utility model, the connection mode between the elastic member 531 and the support column 541 body can be a split connection. For example, it can be fixedly connected by the threaded cooperation of bolts and nuts; or the connection mode between the elastic member 531 and the support column 541 body can also be achieved by welding or integral injection molding, etc., which is not limited herein.

[0045] Specifically, referring to Figure 1 , in the embodiment of the present utility model, the elastic member 531 is a spring. With the above structure, the spring as the elastic member 531 has advantages such as simplicity, reliability, flexibility, cost-effectiveness, high production efficiency, standardization, quality consistency, and customization in terms of structure and manufacturing, providing convenience and support for the design, manufacturing, and performance of the traction mechanism 500.

[0046] It should be noted that in the embodiment of the present utility model, the above spring is a tension spring.

[0047] It can be understood that, referring to Figure 1 , in the embodiment of the present utility model, the link structure 520 includes a first link 521 and a second link 522, and the first link 521 and the second link 522 are arranged at intervals; there are two second sliding members 420, and one ends of the first link 521 and the second link 522 are respectively connected to the two second sliding members 420 in a one-to-one correspondence, and the other ends of the first link 521 and the second link 522 are rotatably connected to the rotating member 510. With the above structure, when the box door 100 is opened, the second sliding member 420 moves and slides relative to the first sliding member 410. As the box door 100 rotates, the first link 521 and the second link 522 rotate, correspondingly driving the rotating member 510 to rotate. The rotation of the rotating member 510 drives the pulling spring, and the traction door panel 300 makes a relative movement with the box door 100; through the design and connection mode among the first link 521, the second link 522, the second sliding member 420, and the rotating member 510, the door panel 300 can move smoothly under the guidance of the second sliding member 420 and the link structure 520.

[0048] Specifically, referring to Figure 1, in the embodiment of the present utility model, the first connecting rod 521 and the second connecting rod 522 are rotationally connected to the rotating member 510. The movement of the first connecting rod 521 and the second connecting rod 522 drives the rotating member 510 to rotate; the connection between the first connecting rod 521 and the second connecting rod 522 and the corresponding first sliding member 410 can be a split connection. For example, it can be fixedly connected by the threaded cooperation of bolts and nuts; or it can also be connected by welding or integrally injection molding, etc., which is not limited herein.

[0049] It can be understood that in some embodiments, the above-mentioned connecting rod structure 520 may also only include one connecting rod member, or may also include three connecting rods, four connecting rods, etc., which is not limited herein, as long as it can realize the rotation of the rotating member 510 and the sliding of the door panel 300 relative to the box door 100.

[0050] Specifically, referring to Figure 1 , according to an embodiment of the present utility model, the distance from the rotation center line of the first connecting rod 521 rotatably connected to the rotating member 510 to the second sliding member 420 is the first length, and the distance from the rotation center line of the second connecting rod 522 rotatably connected to the rotating member 510 to the second sliding member 420 is the second length, and the first length is less than the second length. Through the above structure, the door panel 300 moves in the width direction of the box door 100 away from the elastic structure 530. Since the first length corresponding to the first connecting rod 521 is less than the second length corresponding to the second connecting rod 522, the door panel 300 moves stably, the first sliding member 410 and the second sliding member 420 move in the preset sliding direction, and it is convenient for the rotation of the rotating member 510, improving the stability of the movement.

[0051] Specifically, referring to Figure 1 , according to an embodiment of the present utility model, the connecting rod structure 520 is arranged on one side of the rotating member 510, and the elastic structure 530 is arranged on the opposite side of the rotating member 510.
