Description

Technical Field

[0001] The invention relates to a motion hinge which utilizes damping force to achieve hovering. Background Art

[0002] The door panels of current household appliances are opened and closed by manual suspension or damping shaft suspension. The manual suspension method requires the user to open the door cover manually, and to keep the door cover open, the user needs to hold the door cover with his hand all the time. Closing the door cover also requires the user to close it manually, while the damping shaft suspension method also requires manual closing when closing, which is inefficient and the user experience is not good. Summary of the invention

[0003] The purpose of the invention is to solve the problem that the existing door panel suspension mechanism has low working efficiency and is inconvenient to use.

The guide slide comprises an automatic closing slide which is tangent to the roller and is arranged at the starting end of the guide slide and is used to automatically close the door panel, and an arc-shaped hovering slide which is connected to the automatic closing slide. The starting end of the automatic closing slide is a locking position of the door panel, the connection between the hovering slide and the automatic closing slide is a first hovering position, and the end of the hovering slide is a maximum opening position of the door panel. In the automatic closing slide, the combined force of the tension of the spring on the connecting rod and the damping force of the roller on the connecting rod is greater than the tension of the door panel on the connecting rod, and in the hovering slide, the combined force of the tension of the spring on the connecting rod and the damping force of the roller on the connecting rod is equal to the tension of the door panel on the connecting rod.

[0007] The hovering slide is provided with a T-shaped toothed notch.

[0008] 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.

[0009] When the door panel is closed, the angle between the door panel and the vertical direction is between -2 degrees and 0 degrees.

[0010] The hinge body fixing plate is provided with a U-shaped groove, and a limiting groove for limiting the movement of the upper and lower connecting rods is opened at the bottom of the U-shaped groove.

[0017] The structure of the present invention is further described below in conjunction with the accompanying drawings.

[0018] Reference Figures 1 to 3A motion hinge that uses damping force to achieve suspension 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 that causes the door panel mounting plate to suspend at an angle relative to the hinge body fixing plate, the suspension mechanism 3 includes a connecting rod 31 connecting the door panel mounting plate and the connecting body fixing plate, one end of the connecting rod is hinged to the door panel mounting plate, and a guide slide 32 is provided on the connecting rod, the suspension mechanism also includes a roller 33 provided on the hinge body fixing plate and matched with the guide slide, and a damping mechanism 34 that pulls the connecting rod to roll on the roller to close or suspend the door panel, the guide slide 32 includes an automatic closing slide 321 which is arranged at the starting end of the guide slide and is tangent to the roller and is used to automatically close the door panel, and an arc-shaped hovering slide 322 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 hovering slide and the automatic closing slide is the first hovering position, and the end of the hovering slide is the maximum opening position of the door panel. In the automatic closing slide, the combined force of the tension of the spring on the connecting rod and the damping force of the roller on the connecting rod is greater than the tension of the door panel on the connecting rod. In the hovering slide, the combined force of the tension of the spring on the connecting rod and the damping force of the roller on the connecting rod is equal to the tension of the door panel on the connecting rod. In this embodiment, when the door panel is opened to the first hovering position, the position on the guide slideway that is tangent to the roller is the end position of the first slideway and also the starting end of the hovering slideway; in the automatic closing slideway, the combined force of the tension of the spring on the connecting rod and the damping force of the roller on the connecting rod is greater than the tension of the door panel on the connecting rod, so the door panel can be automatically closed within the range of the automatic closing slideway. When the door panel is opened to the maximum position, the end of the hovering slideway is determined at the contact point of the roller, and the starting point and the end of the hovering slideway are connected by an arc. The shape of the arc of the hovering slideway can be adjusted according to the tension of the damping mechanism and the weight of the door panel, and the combined force of the tension of the spring on the connecting rod and the damping force of the roller on the connecting rod is adjusted so that the combined force of the tension of the spring on the connecting rod and the damping force of the roller on the connecting rod is equal to the tension of the door panel on the connecting rod, thereby achieving the purpose of the door panel hovering. In this embodiment, a T-shaped toothed notch 3221 is provided on the hovering slideway. Thereby increasing the damping force between the hovering slideway and the connecting rod. During specific implementation, the angle between the door panel and the vertical direction can be set to be automatically closed within the acute angle range 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 connecting rod of the motion hinge of the present invention that utilizes the damping force to achieve hovering 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.

[0019] In this embodiment, a U-shaped groove 11 is provided on the hinge body fixing plate 1, and a limiting groove 12 for limiting the movement of the upper and lower connecting rods is provided at the bottom of the U-shaped groove, and the connecting rod passes through the limiting groove and is hinged to the door panel mounting plate. During the movement of the connecting rod, the limiting groove 12 can limit the highest and lowest positions of the connecting rod movement, so that the opening range of the door panel can be further limited by the structure of the automatic closing slide and the hovering slide.

[0020] In this embodiment, the damping mechanism 34 is a spring with one end fixedly connected to the hinge body fixing plate and the other end fixedly connected to the connecting rod. When the door panel is opened, the door panel drives the connecting rod to extend, and the spring is pulled and extended by the connecting rod. In the hovering slide, the tension of the door panel weight on the connecting rod, the tension of the spring on the connecting rod, and the damping force between the roller and the connecting rod reach a balance, and the door panel hovers. In the automatic closing slide, the combined force of the spring tension on the connecting rod and the damping force of the roller on the connecting rod is greater than the tension of the door panel weight on the connecting rod, and the door panel automatically closes.

[0021] In this embodiment, a U-shaped mounting groove 21 is provided on the door panel mounting plate 2, and a connecting rod of the mounting groove is rotatably arranged on the inner side wall of the mounting groove through a connecting rod rotating shaft, so that the hinge connection between the connecting rod and the door panel mounting plate can be stable.

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.
