Abstract
Description
Technical Field
[0001] The utility model relates to a sliding door structure, in particular to a damping buffer door closing structure and a door. Background Art
[0002] In order to facilitate driving, sliding doors are generally provided with rollers on the door bottom frame to reduce friction resistance. While this design reduces friction resistance, it also brings a negative effect. When the door is closed with too much force, the door will hit the door frame. The collision will make a collision noise and will also damage the collision part, affecting the use of the door. To solve this problem, a damping device is added to the sliding door to solve the collision problem. For example, a door panel silent magnetic damping mechanism disclosed in Chinese patent publication number CN220929071U includes a door panel body, the top and bottom of the door panel body are symmetrically provided with mounting grooves, a rubber roller is installed inside the mounting groove, a door frame is installed on the outside of the door panel body, and the top and bottom of the door frame are provided with sliding grooves, and the rubber roller is slidably installed inside the sliding groove, and a housing is symmetrically fixedly installed on the outside of the door panel body, and a magnetic damping component is installed inside the housing. The above patented technical solution can make it easier for the moving wheels on the sliding door panel to achieve a better damping effect when it moves during use, avoiding collisions caused by the door panel moving too fast, thereby increasing the service life. However, the magnetic damping mechanism in the above patented technical solution is complex in structure and high in cost. From the practical point of view, most modern sliding doors are glass doors and windows. How to make the above complex conductive structure smaller and apply it to glass door panels without affecting the appearance of the doors and windows is a difficult problem. If the structure cannot be reduced, it will affect the overall appearance of the doors and windows, and it is difficult for consumers to accept it, and the market value will be greatly reduced. Utility Model Content
[0003] In order to solve the buffering and self-closing problems when a sliding door or a window is closed, the utility model provides a damping buffering door closing structure and a door.
[0004] The utility model is applicable to doors or windows. Taking doors as an example, the following technical solutions are provided:
[0005] A damping and buffering door closing structure comprises an externally fixed door frame and a movable door leaf, wherein the door leaf is slidably or rollingly connected to the door frame, a damping component is provided at the end of the door leaf, and a magnetic adsorption component is provided between the door leaf and the door frame; the magnetic adsorption component comprises two oppositely charged magnets which are respectively arranged parallel to each other between the door frame and the door leaf.

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0018] Example 1: Figures 1 to 3 As shown, a damping buffer door closing structure includes an externally fixed door frame 1 and a movable door leaf 2. The door leaf is slidably or rollingly connected to the door frame, a damping component 3 is provided at the end of the door leaf, and a magnetic adsorption component is arranged between the door leaf and the door frame; the magnetic adsorption component includes two oppositely attracted magnets arranged parallel to each other between the door frame and the door leaf.
[0019] The damping component can use the micro damping buffer device of the prior art. When searching for micro damping on platforms such as Taobao, finished products can be seen, including hydraulic oil pressure, pneumatic and other different products. In this embodiment, any one of them can be used.
[0020] In an optional structure, a groove is provided on the door frame corresponding to the damping assembly, and the impacted head 31 of the damping assembly enters the groove to achieve airtightness between the door frame and the door leaf when the door is closed.
[0021] The magnetic adsorption component comprises two magnets, magnet A41 and magnet B42, magnet A is arranged on the door frame, and magnet B is arranged on the housing of the damping component. The magnetic fields of the two magnets are in the same direction, and there is a gap between the two magnets so that they do not touch each other. In this embodiment, the two magnets may be flat in shape, and the parallel cross-sections of the two magnets may be the same.
[0022] During the closing process of the door leaf, when the impact head 31 of the damping assembly enters the groove and hits the door frame, the damping effect is triggered, and the initial closing speed of the door leaf is reduced. At this time, the two magnets A and B designed and positioned during fixation begin to approach each other, and the magnetic attraction force between them is greater than the damping resistance, which continues to make the door leaf close automatically; when the magnetic fields of magnets A and B are close to overlapping, the magnetic attraction force and the damping resistance reach a balanced state, and the door leaf and the door frame are in a closed state. The above-mentioned magnet structure is designed for sliding doors to achieve the effect of automatic slow closing.
[0023] Embodiment 2: A door having the damping and buffering door closing structure as described above.
