Description

Technical Field

[0001] The utility model relates to a sliding door, in particular to a magnetic suspension sliding door. Background Art

[0002] Conventional sliding doors are connected to the track by rolling or sliding. The weight of the door directly acts on the movable connection parts, which greatly increases the friction resistance, resulting in the door being difficult to push and pull, or even derailed. Especially in large hotels, event venues, high-end residential areas and other occasions, how to reduce the friction resistance caused by the weight of the door and create a movable sliding door that is smooth and low in noise has become a common demand. Utility Model Content

[0004] The utility model provides the following technical solutions:

[0005] A magnetic levitation sliding door comprises a door bottom frame, a door leaf, and a movable mechanism therebetween, wherein the movable mechanism comprises a magnetic track connected to the door bottom frame and a magnetic slider connected to the door leaf, wherein the magnetic track is provided with a guide rail, and the magnetic slider comprises a plurality of slider units; a groove is provided at the bottom of the slider unit to accommodate the guide rail, magnets are installed on both sides of the groove and are magnetically attracted to the guide rail without contact, a positioning wheel is provided at the end of the slider unit to clamp the guide rail to form a rolling connection and limit the position, and the slider unit and the guide rail form magnetic levitation in the vertical direction.

[0006] Preferably, the magnetic track comprises a guide rail seat and a guide rail, and the guide rail is a round rod made of magnetic material.

[0007] Preferably, a pair of positioning wheels are respectively provided at two ends of the slider unit for clamping the guide rail.

[0008] Preferably, two or more sets of magnetic tracks and magnetic slide blocks are arranged side by side in the door bottom frame for supporting the same door leaf.

[0009] Preferably, the door leaf is connected to the middle bracket through a bottom profile, and the middle bracket is connected to the magnetic slider; the bottom profile has an I-shaped cross-section, and a receiving groove is provided on the bottom profile to connect the door leaf; a cover plate is provided between the door leaf and the door bottom frame, the cover plate is connected to the side wall of the door bottom frame, and a gap is provided between adjacent cover plates for the bottom profile to move.

[0010] The beneficial effects of the utility model are:

[0011] (1) Compared with the general suspension formed by magnetic repulsion, the magnetic attraction between the guide rail and the slider unit is utilized, and the positioning wheel is used to limit the contact between them, thereby stabilizing the magnetic attraction and forming a magnetic suspension in the vertical direction. The magnetic suspension structure formed by magnetic attraction in the utility model is more stable.

[0012] (2) It solves the problem of conventional sliding doors being difficult to push and pull and making loud noises due to high friction resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[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. Example

[0018] like Figures 1 to 3 As shown, a magnetic suspension sliding door includes a door bottom frame 1, a door leaf 2, and a movable mechanism therebetween, wherein the movable mechanism includes a magnetic track connected to the door bottom frame and a magnetic slider connected to the door leaf.

[0019] The magnetic track is provided with a guide rail 31, specifically, the magnetic track includes a guide rail seat 32 and a guide rail 31, and the guide rail is a round bar made of magnetic material. Correspondingly, an arc groove can be used to connect the guide rail at the top of the guide rail seat. The round bar can be a permanent magnet or other magnetic material.

[0020] The magnetic slider includes a plurality of slider units 4. The bottom of the slider unit is slotted to accommodate the guide rail. Magnets 41 are installed on both sides of the slot to attract the guide rail magnetically without contact. Positioning wheels 42 are provided at the ends of the slider units to clamp the guide rail to form a rolling connection and limit the position. The slider unit and the guide rail are suspended in the vertical direction. Figure 1 The suspension gap in the middle is small and cannot be displayed. A pair of positioning wheels are respectively arranged at the two ends of the slider unit for clamping the guide rail.

[0021] If quietness is taken into consideration, the positioning wheel can be a plastic roller and the surface of the round rod can be chrome-plated.

[0022] The above-mentioned magnetic suspension sliding door driven by human power does not require any electrical connection. The induction type magnetic suspension sliding door can be adapted to add sensors and micro motors.

[0023] The principle of magnetic levitation is: the magnetic attraction between the guide rail and the slider unit. The magnetic attraction has a curve relationship according to the vertical displacement between the slider unit and the guide rail. The magnetic attraction can provide a vertical force to counteract gravity. The maximum load of the magnetic attraction Fx can range from 10Kg to 300Kg, or even higher. If multiple sets of magnetic tracks and magnetic sliders are used together, they can bear the weight of door panels in various situations.

[0024] To achieve stable magnetic suspension for magnetic tracks and magnetic sliders, multiple parameters between the guide rails and slider units are involved, such as the diameter and length of the guide rails, the width and height of the magnets in the slider units, and the spacing and number of slider units. In order to facilitate installation, several groups of stable parameters are generally selected as groups. For example, according to the diameter of the guide rail, three groups of large, medium and small are formed, each group has a corresponding load-bearing door leaf range, which can be selected during installation.

[0025] In order to accommodate heavier door leaves, two sets of magnetic tracks and magnetic sliders are arranged side by side in the door bottom frame to support the same door leaf. For double doors, two door bottom frames with cavities are selected, such as Figure 1 shown.

[0026] The door leaf is connected to the middle bracket 6 through the bottom profile 5, and the middle bracket is connected to the magnetic slider; the bottom profile has an I-shaped cross section, and a receiving groove is provided on the bottom profile to connect the door leaf; a cover plate 7 is provided between the door leaf and the door bottom frame, and the cover plate is connected to the side wall of the door bottom frame, and a gap is provided between adjacent cover plates for the bottom profile to move. The cover plate can protect the magnetic suspension mechanism, and can also keep the door bottom frame flush with the ground, and keep the door threshold simple in appearance.
