[0018] The structure of the present invention is further described below in conjunction with the accompanying drawings.
[0019] Reference Figures 1 to 4A motion hinge capable of automatic closure includes a hinge body fixing plate 1, a door panel mounting plate 2 hinged to the hinge body fixing plate, the motion hinge also includes a suspension mechanism 3 for causing the door panel mounting plate to suspend at an angle relative to the hinge body fixing plate, the suspension mechanism 3 includes a hinge linkage connecting member 31 connecting the door panel mounting plate and the connecting body fixing plate, and a damping mechanism 32 for pulling the hinge linkage connecting member to slide on the hinge body fixing plate to cause the door panel to suspend, one end of the hinge linkage connecting member is hinged to the door panel mounting plate, and the other end is slidably connected to the hinge body fixing plate, and the hinge body fixing plate is provided with a control mechanism for opening and closing the door panel The suspended guide slide 33, one end of the hinge linkage connecting member is connected to the guide slide through a roller 34, one end of the hinge linkage connecting member is fixedly connected to the roller shaft, the roller is rotatably arranged in the guide slide, the guide slide 33 includes an automatic closing slide 331 arranged at the starting end of the guide slide and having an acute angle with the vertical direction for automatically closing the door panel, and an arc-shaped suspended slide 332 connected to the automatic closing slide, the starting end of the automatic closing slide is the locking position of the door panel, the connection between the suspended slide and the automatic closing slide is the first suspended position, and the end of the suspended slide is the maximum opening position of the door panel. In this embodiment, the door panel automatically closes within an angle of 30 degrees with the vertical direction. When closed, the angle between the door panel and the vertical direction is -2 degrees; suspended between 30 degrees and 88 degrees. When the door panel is opened to the first hovering position of 30 degrees, a first circle is drawn with the hinge point of the hinged connecting member and the door panel, i.e. the hinge point of the door panel, as the center and the distance from the roller shaft to the hinge point of the door panel as the radius, a second circle is drawn with the rotating axis of the door panel as the center and the distance from the rotating axis of the door panel to the hinge point of the door panel as the radius, the intersection of the first circle and the second circle is the end position of the first slide and also the starting end of the hovering slide; when the door panel is opened to the maximum position of 88 degrees, a third circle is drawn with the hinge point of the hinged connecting member and the door panel, i.e. the hinge point of the door panel, as the center and the distance from the roller shaft to the hinge point of the door panel as the radius, a fourth circle is drawn with the rotating axis of the door panel as the center and the distance from the rotating axis of the door panel to the hinge point of the door panel as the radius, the intersection of the third circle and the fourth circle is the end position of the hovering slide, and the starting end of the hovering slide is connected with the end of the hovering slide by an arc to form a hovering slide. During specific implementation, it can be set to automatically close within the range of acute angles with the vertical direction as needed. For example, when the door panel is closed, the angle between the door panel and the vertical direction is between -2 degrees and 0 degrees. During specific implementation, a suitable hovering angle range can be set. For example, when the door panel is hovering at the maximum angle, the angle between the door panel and the vertical direction is between 88 and 90 degrees. The hinge linkage connecting part of the automatically closable motion hinge of the present invention drives the door panel to automatically close in the automatic closing slide, and can hover in the hovering slide. The automatic closing angle and the door panel hovering opening angle can be set as needed, so that it is easy to use and has high work efficiency.
[0020] In this embodiment, when the door panel is closed, a guide slope 11 is provided on the joint surface between the hinge body fixing plate 1 and the door panel mounting plate, and a U-shaped groove 21 matching the guide slope is provided on the door panel mounting plate 2. If the angle between the door panel and the vertical direction is -2 degrees when the door panel is closed, the angle between the guide slope and the vertical direction is -2 degrees, so that the door panel is closed tightly.
[0021] In this embodiment, more than one adjustment hole is provided on the inner side of the bend of the hovering slide, and a detachable adjustment pin 4 for adjusting the traction direction and magnitude of the traction force of the traction rope on the door panel is provided in one of the adjustment holes. When the roller rolls in the hovering slide, the roller drives the traction end of the traction rope to move along the hovering slide, and the traction rope is hung on the adjustment pin. During the movement of the traction rope, the traction force and traction direction are constantly changed by the action of the adjustment pin, so that the position of the adjustment pin can be adjusted according to the weight of the door panel, thereby setting the automatic closing position at different angles and the hovering position at different angles.
[0022] In this embodiment, the damping mechanism 32 includes a traction rope 321 fixedly connected to the roller shaft, a guide wheel 322 for guiding the traction rope, and a damping spring 323 for driving the traction rope to reset. The traction rope is connected to the head end of a spring guide rod 324. A sleeve 325 for guiding the spring guide rod is provided on the hinge body fixing plate. The spring guide rod is slidably sleeved in the sleeve. One end of the spring is connected to the sleeve, and the other end of the spring is connected to a spring stopper provided at the tail end of the spring guide rod. When the roller rolls, the traction rope is driven to pull the spring guide rod to move, so that the spring stopper pushes the spring to compress the spring. When the traction force is cancelled, the spring rebounds and pulls the traction rope to reset.
[0023] In this embodiment, the guide slide protrudes from the hinge body fixing plate. The hinge body fixing plate is made of sheet metal material, and the guide slide is stamped. The guide slide protrudes from the hinge body fixing plate, thereby facilitating the installation of the hinge linkage connector and preventing interference between the hinge linkage connector and the hinge body fixing plate; at the same time, the strength of the guide slide is enhanced, making the guide slide less likely to deform.
[0024] Although the specific embodiments of the present invention are described in detail in conjunction with the accompanying drawings, it should not be understood as limiting the scope of protection of the present invention. Within the scope described in the claims, various modifications and variations that can be made by those skilled in the art without creative work still belong to the scope of protection of the present invention.
