Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically a magnetic suction buffer hinge. Background Technology

[0002] Traditional folding door hinges only serve a connecting function and cannot cushion the door panel during the unfolding process. When the door panel unfolds, due to inertia, collisions, loosening, or damage to the hinges may occur.

[0003] Therefore, we propose a magnetically actuated buffer hinge to address the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a magnetically actuated buffer hinge to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic suction buffer hinge, comprising: a door panel, wherein a magnetic suction hinge is installed at the joint between the upper and lower ends of two adjacent door panels;

[0006] The magnetic hinge includes a first hinge arm and a second hinge arm, which are rotatably connected by a hinge pin.

[0007] The first hinge arm and the second hinge arm are respectively provided with magnetic attraction structures on their opposite sides after being folded.

[0008] One of the first hinge arm and the second hinge arm has an embedded elastically mounted buffer. The buffer moves through one of the magnetic structures. In the folded state, the buffer retracts when it contacts the other magnetic structure.

[0009] Preferably, the first hinge arm is fixedly mounted on the first fixed bracket, and the second hinge arm is fixedly mounted on the second fixed bracket.

[0010] Preferably, the first fixed bracket and the second fixed bracket are fixedly installed to the two door panels respectively by fixing screws.

[0011] Preferably, the magnetic attraction structure includes a first magnetic plate and a second magnetic ring. The first magnetic plate is fixedly installed on the side of the first hinge arm, and the second magnetic ring is fixedly installed on the side of the second hinge arm. When the first hinge arm and the second hinge arm are folded to a certain angle, the first magnetic plate and the second magnetic ring magnetically attract each other.

[0012] Preferably, a buffer is also elastically installed inside the second hinge arm, the buffer passes through the second magnetic ring, and a spring is installed between the buffer and the second hinge arm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the combined action of buffering and magnetic attraction, it can prevent the door panel from not closing properly due to insufficient closing force, and also prevent the door panel from colliding, loosening or damaging the hinges due to inertia.

[0015] 2. Combining the buffer with the magnetic attraction device results in even force distribution and saves space. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a magnetic buffer hinge, including: a door panel 1, and a magnetic hinge 2 installed at the joint of the upper and lower ends of two adjacent door panels 1, thereby realizing the folding and unfolding of the door panel 1.

[0022] The magnetic hinge 2 includes a first hinge arm 21 and a second hinge arm 22, which are rotatably connected by a hinge pin 26.

[0023] The first hinge arm 21 is fixedly installed on the first fixed bracket 27, and the second hinge arm 22 is fixedly installed on the second fixed bracket 28. The first fixed bracket 27 and the second fixed bracket 28 are respectively fixedly installed on the two door panels 1 by fixing screws 29.

[0024] This allows the two door panels 1 to rotate and unfold or fold around the hinge pin 26.

[0025] The first magnetic plate 25 is fixedly installed on the side of the first hinge arm 21, and the second magnetic ring 23 is fixedly installed on the corresponding side of the second hinge arm 22. The first magnetic plate 25 and the second magnetic ring 23 magnetically attract each other when they are close together. When the two door panels 1 are unfolded relative to each other, the first hinge arm 21 and the second hinge arm 22 fold relative to each other. When the critical point is reached, the first magnetic plate 25 and the second magnetic ring 23 magnetically attract each other, so that the first hinge arm 21 and the second hinge arm 22 are completely folded in half, thereby realizing the automatic magnetic unfolding of the two door panels 1.

[0026] A buffer 24 is also elastically installed inside the second hinge arm 22. The buffer 24 passes through the second magnetic ring 23, and a spring is installed between the buffer 24 and the second hinge arm 22. When the first hinge arm 21 and the second hinge arm 22 approach the magnetic attraction, the buffer 24 provides cushioning.

[0027] Working principle: In the folded state, the distance between the first magnetic plate 25 and the second magnetic ring 23 is relatively far, and there is no force between them. When the door panel 1 needs to be unfolded to close the door, the first hinge arm 21 and the second hinge arm 22 will rotate around the hinge pin 26, and the first magnetic plate 25 and the second magnetic ring 23 will move closer to each other. When a certain threshold is reached, the magnetic fields of the first magnetic plate 25 and the second magnetic ring 23 will generate mutual attraction. The magnetic force will promote the first hinge arm 21 and the second hinge arm 22 to fold together. When it is about to fold, the first magnetic plate 25 will squeeze the buffer 24 to buffer the inertial force in the final closing stage, thereby avoiding collisions caused by inertia during the unfolding of the magnetic hinge 2.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
