Description

TECHNICAL AREA

The present invention relates to the technical field of furniture hinges, specifically to a furniture drive actuator usable for load adjustment over a wide range.

STATE OF THE ART

A furniture hinge is typically used to assemble and connect a cabinet body and a door panel together. In particular, in a hinge of a flip-up door, an actuator driving device that drives the door panel to move is mounted.

A Chinese patent ( CN103477011B ) discloses an actuator drive device for driving a flap door of a piece of furniture to move. The disclosed actuating drive device, which is used to drive a flap door of a piece of furniture to move, comprises at least one actuating arm, which is used to set the flap door in motion and is pivotally mounted, a spring mechanism, which is used to apply a pivoting moment to the actuating arm in the opening direction, and an adjustment mechanism with a threaded adjustment bolt. The pivoting moment of the spring mechanism acting on the actuating arm can be adjusted by rotating the adjusting bolt; The adjustment bolt has a bolt rod and a nut is adjustably mounted along the bolt rod by a rotary movement of the adjustment bolt; The adjusting bolt has a locking mechanism which is separate from the thread and which prevents an undesired rotary movement of the adjusting bolt. Thus, through the cooperation of the adjusting bolt, which is designed as above, with a nut, the outputting of different torques is achieved with one and the same device.

1. 1) Die obige Verstellvorrichtung ist kompliziert ausgestaltet und an ihre Zusammenwirkung mit dem Betätigungsarm wird eine hohe Genauigkeitsanforderung gestellt. Ansonsten wird eine Schwergängigkeit des Betätigungsarms verursacht, die Bewegungsübertragungsfähigkeit gesenkt und selbst der normale Betrieb der Türplatte beeinträchtigt.
2. 2) Bei einer manuellen Anpassung des Verstellbolzens in der obigen Verstellvorrichtung kann die Mutter entlang der Bolzenstange bewegt werden, sodass sich die Position des Angriffspunkts des Federmechanismus relativ zu der Drehachse der Betätigungsstange ändert und somit der Angriffspunkt des Federmechanismus indirekt angepasst wird. Aufgrund des kleinen Einstellbereichs ist eine Anpassung an die Anwendung bei Möbeln, bei denen eine Lasteinstellung in einem großen Bereich erwünscht ist, schwer zu erwarten, was zu einem begrenzten Anwendungsbereich führt.

However, when the above actuator driving device is put to practical use, there are the following disadvantages:

1. 1) The above adjusting device has a complicated design and a high degree of accuracy is required of its interaction with the actuating arm. Otherwise, the operating arm will become sluggish, the motion transmission ability will be lowered, and even the normal operation of the door panel will be affected.
2. 2) When manually adjusting the adjusting bolt in the above adjusting device, the nut can be moved along the bolt rod, so that the position of the point of application of the spring mechanism changes relative to the axis of rotation of the operating rod, and thus the point of application of the spring mechanism is indirectly adjusted. Because of the small adjustment range, adaptation to furniture application where load adjustment over a wide range is desired is difficult to expect, resulting in a limited range of application.

DETAILED DESCRIPTION

The present invention is described in more detail below with reference to the drawings.

It will be on 1 until 5 pointed out. The furniture driving actuator usable for load adjustment in a wide range according to the present invention comprises a driving device for moving a door panel of a piece of furniture. The drive device comprises a drive body 1 for attachment to a cabinet body, a connecting rod assembly 2 which rotates the door panel, a spring assembly 3 which provides a driving force, and an adjustment mechanism 4 for initial adjustment. The adjusting mechanism 4 is rotatably arranged on the drive body 1 via a positioning rivet 5 and the adjusting mechanism 4 forms an upper lever portion b and a lower lever portion a, using the positioning rivet 5 as a fulcrum, which pivot like a lever. The top of the upper lever portion b is connected to the connecting rod assembly 2 . The adjusting mechanism 4 is provided with a carriage 6 for adjusting the length of the lower lever portion a. The carriage 6 is slidably connected to the lower portion of the lower lever portion a. One end of the spring assembly 3 is fixedly connected to the drive body 1 and the other end is rotatably connected to the carriage 6 .

By adjusting the position of the carriage 6, the length of the lower lever portion a can be adjusted, thus adjusting the load-force ratio of the upper lever portion b and the lower lever portion a in the adjustment mechanism 4 to change the magnitude of the output force of the spring assembly 3 and to meet the load change requirements of different door panels, achieving easy operation and good applicability.

It will be on 1 until 3 pointed out. In detail, the adjustment mechanism 4 includes a power arm 41, a support piece 42, a ratchet wheel 43, and a moving shaft 44. The power arm 41 is rotatably connected to the drive body 1 via the positioning rivet 5. As shown in FIG. The top portion of the power arm 41 is connected to the connecting rod assembly 2 . The support piece 42 is attached to the lower area of the power arm 41 . The ratchet wheel 43 is rotatably connected to the support piece 42 . The movement shaft 44 is threadedly connected to the ratchet wheel 43, which rotates to drive the movement shaft 44 to move forward and backward. The carriage 6 is attached to the moving shaft 44 and moves forward and backward with the moving shaft 44 accordingly. That is, the carriage 6 is attached to the moving shaft 44 . The carriage 6 is rotatable but not movable relative to the movement shaft 44 and can move with the movement shaft 44 . Accordingly, the spring arrangement 3 can be rotated relative to the carriage 6 . Such a connection is characterized by a simple structure and high stability.

At this time, the support piece 42 is provided with a positioning locking recess 45 to which an end portion of the ratchet wheel 43 is snapped. The support piece 42 is attached to the lower portion of the power arm 41 via a mounting pin 46; The power arm 41 is provided with a limit pin 47 which causes the ratchet wheel 43 to rotate in a certain direction. The limit pin 47 is attached to the power arm 41 between the ratchet wheel 43 and the carriage 6 . Thus, loosening of the ratchet wheel 43 is avoided, structural stability is increased, and load adjustability for the door panel is secured.

Due to the limitation by the support piece 42 and the limitation pin 47, the ratchet wheel 43 can only rotate. By rotating the ratchet wheel 43, the movement shaft 44 is driven to move forward and backward. Accordingly, the carriage 6 moves back and forth, thereby changing the value of the lower lever portion a, which in turn changes the ratio of the upper lever portion b to the lower lever portion a. In this way, by means of the structural cooperation of the force arm 41, the support piece 42, the ratchet wheel 43, the movement shaft 44 and the carriage 6 of the adjustment mechanism 4, a change in the output force of the spring arrangement 3 is achieved. Thus, the requirement of load change in various door panels can be met, and besides the simple structure and high stability, the quality of use of the door panel is ensured.

The lower area of the power arm 41 is provided with a sliding guide groove 48 on both sides. The carriage 6 is provided with an alignment projection 49 on both sides thereof, which slides in cooperation with the guide sliding groove 48 . This increases the stability of the setting and ensures the accuracy of the setting.

Furthermore, the power arm 41 is provided with a through hole 410 for rotating the ratchet wheel 43 on both sides, respectively. This facilitates operation and ensures normal use of the door panel.

It will be on 1 until 5 pointed out. The lower end of the force arm 41 is provided with an angle adjustment wheel 10 for adjusting the pivoting distance. One end of the angle adjusting wheel 10 is rotatably connected to and positioned on the lower portion of the driving body 1, while the other end of the angle adjusting wheel 10 is connected to the power arm 41 via a thread. In cooperation with the angle adjustment wheel 10, the pivoting distance of the adjustment mechanism 4 is effectively adjusted, thus further adjusting the load-force ratio of the power arm 41 and thus adjusting the load of the door panel, which allows adaptation to use in door panels with a large load.

It will be on 1 until 5 pointed out. The drive body 1 is provided with a mounting sleeve 7 which is provided with a damping cylinder 8 and an adjustment wheel 9 for adjusting the damping force of the damping cylinder 8 . The damping cylinder 8 is slidably installed in the mounting sleeve 7 which is connected at one end via a thread to the adjustment wheel 9 which is fixedly connected to a push rod of the damping cylinder 8 . The connecting rod arrangement 2 is arranged folded up on the drive body 1 and at the same time rests against the damping cylinder 8 . Under the influence of the cushioning cylinder 8, the cushioning effect is improved, the service life of the door panel is extended, and the quality of use of the door panel is improved.

The above concrete examples are only concrete examples having good effects of the invention. Any configurations having the same or equivalent structure as the wide-range load adjustment furniture power actuator of the invention are within the scope of the invention.
