For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] Firstly, referring to Figures 1-9 The door plate structure of the present application is described.

[0043] As Figures 1-9As shown, in order to solve the problem of noise generated by shaking of the existing door panel during movement, the door panel structure of the present application includes a door frame 1, a sliding assembly 3, a door panel and a roller assembly 4. Among them, the door frame 1 forms an interlayer space 141 with an opening on at least one side along the first direction or the second direction. The sliding assembly 3 is arranged in the interlayer space 141 and is configured to be able to move between a first position and a second position. The door panel is rotatably connected to the sliding assembly 3 and is configured to be able to rotate around the sliding assembly 3 to open or close the opening, and when the door panel is parallel to the interlayer space as a whole, it can enter and exit the interlayer space 141 under the drive of the sliding assembly 3. The roller assembly 4 is arranged on at least one side wall along the first direction and the second direction in the interlayer space 141, and is configured so that the roller 42 thereon can abut against the door panel and can rotate as the door panel moves.

[0044] The present application sets a roller assembly 4 on at least one side wall in the interlayer space 141. The roller 42 on the roller assembly 4 can abut against the door panel and can also rotate with the movement of the door panel, thereby improving the stability of the door panel during movement, avoiding noise caused by shaking of the door panel during movement, and greatly improving the user experience.

[0045] Further reference below Figures 1-9 A preferred embodiment of the door panel structure of the present application is described below. Those skilled in the art will understand that the following embodiments are merely intended to illustrate the principles of the present application and are not intended to limit the scope of protection of the present application. Assuming that the door panel structure comprises at least a door frame 1, a sliding assembly 3, a door panel, and a roller assembly 4, those skilled in the art may adjust the following configuration to adapt the present application to more specific application scenarios.

[0046] The first direction refers to Figures 1-9 The X direction is shown, which includes the positive direction and the negative direction indicated by the arrow. The second direction refers to Figures 1-9 The Z direction shown includes the positive direction and the negative direction indicated by the arrow. The third direction refers to the direction indicated by the arrow. Figures 1-9 The Y direction is shown, which includes a positive direction and a negative direction indicated by arrows.

[0047] like Figures 1-9 As shown, in a more preferred embodiment, the door panel structure includes a door frame 1 , a sliding assembly 3 , a door panel, a roller assembly 4 and a first elastic arm 5 .

[0048] Reference Figures 1-9The door frame 1 comprises a first door frame plate 11, a second door frame plate 12 and a third door frame plate 13. The first door frame plate 11 and the third door frame plate 13 are arranged on two sides of the second door plate 22 along the first direction and symmetrically relative to the second door frame plate 12. The second door frame plate 12 is arranged on a side of the first door frame plate 11 and the third door frame plate 13 along the third direction. The second door frame plate 12 is provided with an opening, which is a first opening 121. The first door frame plate 11 and the third door frame plate 13 are each formed with a sandwich space 141 having a second opening. The first opening 121 and the two second openings are located on the same side along the third direction. Each sandwich space 141 is spaced apart from the inner side wall of the second door frame plate 12 along the first direction and is provided with three slides 6 from top to bottom. Each slide 6 extends along the third direction. Each slide 6 is slidably provided with a sliding assembly 3. Each sliding assembly 3 can move along the corresponding slide 6 between a first position and a second position.

[0049] Of course, the positions of the first door frame plate 11 and the third door plate 2 are not fixed in the present application. Those skilled in the art can adjust them as needed. For example, the first door frame plate 11 and the third door frame plate 13 can be arranged on two sides of the first door frame plate 12 along the second direction.

[0050] In addition, the positions of the slides 6 are not fixed in the present application. Those skilled in the art can adjust them as needed. For example, the slide 6 can also be arranged on a side of the sandwich space 141 away from the second door frame plate 12 along the first direction. Alternatively, the slide 6 can be arranged on both inner walls of the sandwich space 141 along the first direction.

[0051] Next, referring to FIG. 2, the sliding assembly 3 comprises a sliding plate 31, a sliding rail 32 and a sliding rail 33. The sliding plate 31 is arranged on the slide 6. The sliding rail 32 is arranged on the sliding plate 31 and extends along the first direction. The sliding rail 33 is arranged on the sliding plate 31 and extends along the third direction. Figures 1-9, the number of door panels is 2, that is, including the first door panel 21 and the second door panel 22, the first door panel 21 and the second door panel 22 are oppositely arranged, by arranging the door panel in the opposite structure, the opening space of the door panel is reduced, and the space utilization is improved. The first door panel 21 is rotatably connected to the first door frame plate 11 through the three sliding assemblies 3 on the first door frame plate 11, so that the first door panel 21 rotates around the sliding assemblies 3, thereby enhancing the stability of rotation, in addition, the first door panel 21 can also smoothly enter and exit the interlayer space 141 in the first door frame plate 11 along the sliding assemblies 3. The second door panel 22 is rotatably connected to the second door frame plate 12 through the three sliding assemblies 3 on the second door frame plate 12, so that the second door panel 22 rotates around the sliding assemblies 3, thereby enhancing the stability of rotation, in addition, the second door panel 22 can also smoothly enter and exit the interlayer space 141 in the second door frame plate 12 along the sliding assemblies 3. During the rotation of the first door panel 21 and the second door panel 22 around the sliding assemblies 3, the second door frame plate 12 can be covered or exposed, thereby opening or closing the first opening 121, to realize the opening or closing of the door panel. When the first door panel 21 and the second door panel 22 are both covered on the second door frame plate 12, the first opening 121 can be closed, and when the first door panel 21 and the second door panel 22 are both in the open state, the second door frame plate 12 can be exposed, thereby opening the first opening 121.

[0052] Of course, the number of door panels arranged in the present application is not fixed, and those skilled in the art can adjust it according to the specific application scene. For example, the number of door panels is 1, and by using one door panel, the first opening 121 can also be opened or closed. When the number of door panels is 1, the interlayer space 141 does not need to be formed on the first door frame plate 11 and the second door frame plate 12 at the same time, only the interlayer space 141 needs to be formed on the first door frame plate 11 or the second door frame plate 12, and the sliding assembly 3 in the interlayer space 141 can also make the door panel rotate to open or close the first opening 121, at this time only one interlayer space 141 is arranged, and the size of the space in the third direction is larger than that of the two opposite door panels.

[0053] In addition, the number of sliding rails 6 arranged in the present application is not fixed, and those skilled in the art can adjust it according to the need. For example, the number of sliding rails 6 can also be 1, 2, 4 or other numbers, at this time the number of sliding assemblies 3 matches the number of sliding rails 6. When the number of sliding rails 6 is 1, the size of the door panel can be relatively small at this time to ensure the stability of the door panel during rotation and movement.

[0054] Next, referring to Figures 2-3The first door plate 21 is provided with a first installation slot 231 on the side close to the second door frame plate 12 when the first door plate 21 is in the closed state, and the first installation slot 231 is provided with a first elastic arm 5. The cross section of the first elastic arm 5 is linear, and the first elastic arm 5 is arranged obliquely, that is, one end of the first elastic arm 5 is arranged in the first installation slot 231, and the other end of the first elastic arm 5 extends out of the slot of the first installation slot 231. Therefore, during the closing process of the first door plate 21, the end of the first elastic arm 5 extending out of the first installation slot 231 can be in contact with the door frame 1 before the first door plate 21, which can buffer the impact of the first door plate 21 on the door frame 1, thereby reducing noise and damage. In addition, as the angle between the first door plate 21 and the second door frame plate 12 gradually decreases, the first elastic arm 5 is gradually pressed into the first installation slot 231 by the second door frame plate 12.

[0055] Of course, the position of the first elastic arm 5 is not fixed in the present application, and those skilled in the art can adjust it according to the needs. For example, the first installation slot 231 can also be arranged on the side close to the second door frame plate 12 of the second door plate 22 when the second door plate 22 is in the closed state, and the first installation slot 231 is provided with the first elastic arm 5. Therefore, during the closing process of the second door plate 22, the end of the second elastic arm extending out of the first installation slot 231 can be in contact with the door frame 1 before the second door plate 22, which can buffer the impact of the second door plate 22 on the door frame 1, thereby reducing noise and damage. In addition, as the angle between the second door plate 22 and the second door frame plate 12 gradually decreases, the first elastic arm 5 is gradually pressed into the first installation slot 231 by the second door frame plate 12.

[0056] In addition, the way of reducing the impact of the door plate and the door frame 1 is not fixed in the present application, and those skilled in the art can adjust it according to the needs. For example, a second installation slot corresponding to the first door plate 21 can also be arranged on the side of the second door frame plate 12 close to the first door plate 21 in the closed state, and a second elastic arm can be arranged in the second installation slot. The second elastic arm is arranged obliquely, that is, one end of the second elastic arm is arranged in the second installation slot, and the other end extends out of the second installation slot, so that during the closing process of the first door plate 21, the end of the second elastic arm extending out of the second installation slot can contact the door frame 1 first. In addition, a second installation slot corresponding to the second door plate 22 can also be arranged on the side of the second door frame plate 12 close to the second door plate 22 in the closed state, and a second elastic arm can be arranged in the second installation slot. The second elastic arm is arranged obliquely, that is, one end of the second elastic arm is arranged in the second installation slot, and the other end extends out of the second installation slot, so that during the closing process of the second door plate 22, the end of the second elastic arm extending out of the second installation slot can contact the door frame 1 first. Alternatively, a second installation slot corresponding to the first door plate 21 can be arranged on the side of the second door frame plate 12 close to the first door plate 21 in the closed state, and a second elastic arm can be arranged in the second installation slot. In addition, a second installation slot corresponding to the second door plate 22 can be arranged on the side of the second door frame plate 12 close to the second door plate 22 in the closed state, and a second elastic arm can be arranged in the second installation slot. At this time, the first door plate 21 and / or the second door plate 22 are not provided with the first installation slot 231 and the first elastic arm 5.

[0057] In addition, the form of the first elastic arm 5 is not fixed in the present application, and those skilled in the art can adjust it according to the specific application scene. For example, the cross-sectional shape of the first elastic arm 5 can also be curved or broken line type, which is also conducive to the end of the first elastic arm 5 extending out of the first installation slot 231 to contact the door frame 1 first during the closing process of the first door plate 21 and the second door plate 22. When the cross-section of the elastic arm is a straight line type, it can be an obliquely arranged elastic sheet. When the cross-section of the first elastic arm 5 is a curved type, it can be a curved elastic sheet protruding towards the door frame 1, or it can also be a curved elastic sheet recessed towards the door plate. When the cross-section of the first elastic arm 5 is a broken line type, it can be a folded elastic sheet arranged in a fold.

[0058] It should be noted that in other preferred embodiments, the first installation slot 231 is not necessarily provided, and those skilled in the art can select it according to the needs. In the case where the first installation slot 231 is not provided, one end of the first elastic arm 5 can be directly arranged on the door plate, and the other end is a free end, and there is a gap between the free end and the door plate. In addition, when the second elastic arm is present, one end of the second elastic arm can also be directly arranged on the second door frame plate 12, and the other end is a free end, and there is a gap between the free end and the second door frame plate 12.

[0059] See next Figures 2-3 A first limiting column 142 is provided on the side of the second door frame plate 12 close to the first door panel 21 in the closed state. The size of the first limiting column 142 in the third direction is smaller than the distance from the end of the first elastic arm 5 extending out of the first mounting groove 231 to the second door panel 22, so that during the closing process of the first door panel 21, the end of the first elastic arm 5 extending out of the first mounting groove 231 can contact the door frame 1 before the first door panel 21.

[0060] Of course, the number of first limiting posts 142 provided in this application is not fixed, and those skilled in the art can adjust it as needed. For example, the number of first limiting posts 142 can be two, three, four, or another number. When there are two or more first limiting posts 142, multiple first limiting posts 142 can be spaced apart and arranged at positions on the second door frame plate 12 corresponding to the first door panel 21 in the closed state.

[0061] In addition, the present application does not provide a fixed location for the positioning post, and those skilled in the art may adjust the location based on specific application scenarios. For example, a second positioning post may be provided on the side of the first door panel 21 that is adjacent to the second door frame panel 12 when the first door panel 21 is in the closed state. Alternatively, a second positioning post may be provided only on the side adjacent to the second door frame panel 12 when the first door panel 21 is in the closed state, and the first positioning post 142 may not be provided in this case. In other preferred embodiments, the provision of the first positioning post 142 and the second positioning post is not required, and those skilled in the art may select the position based on their needs.

[0062] It should be noted that when the second door panel 22 is in a closed state, a first mounting groove 231 is provided on a side close to the second door frame plate 12, and a first elastic arm 5 is provided in the first mounting groove 231. A first limiting column 142 can also be provided on the second door frame plate 12 on a side close to the second door panel 22 in a closed state.

[0063] See next Figures 2-3 A groove 122 is provided on the side of the second door frame plate 12 away from the door panel. Groove 122 corresponds to the first limiting post 142 in the third direction and extends to the first limiting post 142. A first magnetic member, which is a magnet 7, is provided in groove 122. A second magnetic member, which is an iron sheet 8, is provided in the first door panel 21. The second magnetic member corresponds to the position of the first limiting post 142 when in the closed state, thereby facilitating the closing of the first door panel 21.

[0064] Of course, the specific forms of the first magnetic member and the second magnetic member are not fixed, as long as the first magnetic member and the second magnetic member can be magnetically connected. For example, the first magnetic member can be the iron sheet 8, and the second magnetic member can be the magnet 7. Alternatively, the first magnetic member and the second magnetic member can be magnets that attract each other.

[0065] In addition, the specific positions of the first magnetic member and the second magnetic member are not fixed, and a person skilled in the art can adjust them as needed. For example, in the case where the first limiting column 142 and the groove 122 are not arranged, the first magnetic member can be arranged in the second door frame plate 12; alternatively, the first magnetic member can be arranged on the side of the second door frame plate 12 close to the first door plate 21 in the closed state, and / or the second magnetic member can be arranged on the side of the first door plate 21 close to the second door frame plate 12 in the closed state.

[0066] In addition, the number of the first magnetic members is not fixed, and a person skilled in the art can adjust it as needed. For example, the number of the first magnetic members can be two, three, or other numbers, and the number of the second magnetic members is the same as that of the first magnetic members, and the positions of the second magnetic members correspond to those of the first magnetic members. When the number of the first magnetic members is two or more, the first magnetic members can be arranged at positions corresponding to the first door plate 21 in the closed state on the second door frame plate 12.

[0067] It should be noted that the first magnetic members can also be arranged on the second door frame plate 12 close to the second door plate 22 in the closed state, and the second door plate 22 can be arranged with the second magnetic members. The specific arrangement manner is the same as that of the first door plate 21 and the second door frame plate 12, which will not be described here.

[0068] Next, referring to FIG. 3, Figure 7 The sliding assembly 3 includes a sliding member 31 slidingly arranged on the sliding rail 6 and a connecting member 32. The sliding member 31 is arranged with a first rotating structure, which is a connecting hole. The connecting member 32 is arranged with a second rotating structure, which is a connecting shaft 321, rotatingly matched with the first rotating structure. The connecting shaft 321 is inserted into the connecting hole, so that the connecting member 32 can rotate around the sliding member 31. The first door plate 21 is connected with the connecting member 32 on the first door frame plate 11, so that the first door plate 21 can be rotated when the connecting member 32 rotates around the sliding member 31, to realize the closing or opening of the first door plate 21. The second door plate 22 is connected with the connecting member 32 on the third door frame plate 13, so that the second door plate 22 can be rotated when the connecting member 32 rotates around the sliding member 31, to realize the closing or opening of the second door plate 22.

[0069] Of course, the application is not fixed to the rotation connection mode of the first rotation structure and the second rotation structure, and those skilled in the art can adjust it according to the needs. For example, the first rotation structure is a connecting shaft, and the second rotation structure is a connecting hole; or the first rotation structure is a first hinged piece, and the second rotation structure is a second hinged piece, and the first hinged piece and the second hinged piece are hinged through a hinge shaft.

[0070] Next, referring to Figure 8 The slide 6 is provided with a slide groove extending in the third direction, and the cross section of the slide groove is T-shaped. The sliding member 31 is provided with a sliding block 311 matched with the slide groove, so that the sliding block 311 can also prevent the sliding member 31 from falling off the slide 6 during movement. The sliding block 311 can move along the slide groove, so that the sliding member 31 can move between the first position and the second position. When the sliding member 31 is in the first position, it is close to the second opening, and because the connecting piece 32 is rotationally connected with the sliding member 31, when the first door plate 21 and the second door plate 22 rotate, the first opening 121 can be opened or closed. When the first door plate 21 and the second door plate 22 are in a 90° open state, the door plates are parallel to the interlayer space 141, so that the sliding member 31 can move along the slide 6 between the first position and the second position, and thus the first door plate 21 and the second door plate 22 can enter or exit the corresponding interlayer space 141.

[0071] Of course, the application is not fixed to the cross-sectional shape of the slide groove, and those skilled in the art can adjust it according to the specific application scenario. For example, the cross-sectional shape of the slide groove can be L-shaped or other shapes, and at this time the cross-sectional shape of the sliding block 311 is matched with the shape of the slide groove, so that the sliding block 311 can move along the slide groove while preventing the sliding block 311 from falling out of the slide groove.

[0072] It should be noted that when the slide 6 is arranged on both inner walls in the first direction in the interlayer space 141, the sliding block 311 needs to cooperate with the two slides 6 at the same time.

[0073] Next, referring to Figure 7 The two side walls in the first direction in the interlayer space 141 are each provided with a roller assembly 4, and each roller assembly 4 includes a roller seat 41 and a roller 42. The roller seat 41 is arranged on the side wall, and the roller 42 is rotationally arranged on the roller seat 41. The roller 42 abuts against the door plate, which can improve the stability of the door plate during movement. The axis direction of the roller 42 extends in the third direction, so that when the door plate enters or exits the interlayer space 141 under the action of the sliding assembly 3, the roller 42 can rotate with the movement of the door plate. Since the roller 42 abuts against the door plate and rotates with the movement of the door plate, the silent effect of the door plate when entering or exiting the interlayer space 141 can be improved.

[0074] Of course, the application is not fixed to the setting position and the setting number of the sliding assembly 3, and those skilled in the art can adjust it according to the needs.
