Description

Door opening and closing device integrating ejection and rotation

Technical Field

The utility model belongs to the technical field of household appliances, and particularly relates to an ejection and rotation integrated door opening and closing device.

Background

The refrigerator, the oven, the wine cabinet and the like relate to household appliances with rotary doors, and the arrangement of an automatic door opening and closing device for driving the door body to open and close automatically is an important ring for intelligent upgrading. Taking a refrigerator as an example, the resistance for opening the refrigerator door is large due to factors such as the difference between the air pressure inside and outside the refrigerator, the suction force of a door seal and the like, and the automatic door opening and closing device can overcome the resistance and realize the opening and closing of the door body.

Most of automatic opening and closing devices in the current market are incompatible with manual opening and closing functions or large mechanical resistance needs to be overcome during manual operation, and through development and improvement in recent years, a small number of door opening and closing devices which are controlled by an electromagnetic clutch to be powered on and off and simultaneously achieve low-damping manual operation appear, for example, a rotary actuator disclosed in patent CN212752039U of our company. However, this type of solution requires the use of an electromagnetic clutch, increasing the production costs. In addition, in the conventional door opening and closing device, if the rotation angle of the door opening and closing device is large, the waiting time of a user is long, and the door opening and closing device needs to retreat to the outside of a sector area swept by the door body to avoid collision. If the rotation angle of the door opening and closing device is small, the mechanical resistance from the door opening and closing device also needs to be overcome when the user subsequently opens the door manually to the full-open state, and similarly, if the electromagnetic clutch is arranged, the cost is also increased. In addition, under the condition of large door opening resistance, especially for the opening of a refrigerator, a push rod actuator is often arranged in a matching manner to push a door body away in the initial stage of opening the door, which may cause certain interference when a user manually closes the door.

Wherein the third trigger 73 is a micro switch.

Specifically, the elastic press-fit connection of the driving shaft 51 and the driven shaft 52 takes the following form. The rotary driving member 5 further comprises a pull rod 53, a gasket 54, a pressure spring 55 and an adjusting nut 56; the pull rod 53 is arranged along the common rotation axis of the driving shaft 51 and the driven shaft 52, one end of the pull rod 53 is fixedly connected with the driving shaft 51, and the other end of the pull rod 53 penetrates through the driven shaft 52 and is marked as an adjusting end; an adjustment nut 56 is threadedly coupled to the adjustment end; the washer 54 and the compression spring 55 are sleeved on the pull rod 53 and are positioned between the adjusting nut 56 and the driven shaft 52.

In this embodiment, a proximity inductive switch 9 is further arranged between the body and the door body, and the proximity inductive switch 9 is specifically located in the middle of the upper edge of the door body.

The following describes several typical working states to further illustrate the working principle of the ejection and rotation integrated door opening and closing device.

The initial state: as shown in fig. 9 and 10, when the door body is closed, the ejector 3 retracts, the incomplete gear 4 is just meshed with the meshing part 31, and the convex strip 521 is located between the first abutting surface 611 and the second abutting surface 612; the first trigger 71 is triggered, the second trigger 72 is not triggered, and the proximity sensitive switch 9 is triggered.

A first door opening state: as shown in fig. 11 and 12, when the door body is opened by a smaller angle, the ejector 3 is ejected, the incomplete gear 4 is engaged with the meshing part 31, and the convex strip 521 is close to the first abutting surface 611 or abuts against the first abutting surface 611; the first trigger 71 is not triggered, the second trigger 72 is triggered, and the proximity sensitive switch 9 is not triggered.

The second door opening state: as shown in fig. 13 and 14, when the door body is opened at a larger angle, the ejector 3 retracts, the incomplete gear 4 is just meshed with the meshing part 31, and the convex strip 521 is close to the second abutting surface 612 or abuts against the second abutting surface 612; the first trigger 71 is triggered, the second trigger 72 is not triggered, and the proximity sensor switch 9 is not triggered.

A door closing state: as shown in fig. 15 and 16, when the door body is closed, the ejector 3 retracts, the incomplete gear 4 is not engaged with the meshing part 31, and the convex strip 521 abuts against the second abutting surface 612; the first trigger 71 is not triggered, the second trigger 72 is triggered, and the proximity sensitive switch 9 is triggered.

In the initial state, the door body can be opened manually or ejected out by a small angle automatically to enter the first opening state. In the initial state, since a large angular difference exists between the protrusion 521 and the second engagement surface 612, the door body can be manually opened without interfering with the protrusion 521. In the initial state, the power unit may also be turned on, and the incomplete gear 4 is driven to rotate so as to extend the protruding strip 521, so as to push the door body open, thereby entering the first door opening state.

After entering the first door opening state, the power unit immediately provides reverse power to enable all parts of the ejection and rotation integrated door opening and closing device to recover to the initial state standby state. After the door body enters the first door opening state, the door body is already pushed away by a certain angle, and the stage of the maximum door opening resistance is passed, so that the resistance required to be overcome by the rotation of the door body is extremely small, the door body can be further pulled away by a single finger easily, and the door body can be further opened by squeezing or rubbing at elbows, knees and other parts, so that the door body enters the second door opening state.

When the door body is not closed, the power unit may be started to rotate the rotary driving member 5, so that the protruding strip 521 is swept toward the direction close to the second abutting surface 612, and the door body is further driven to close after abutting until the door body reaches the closed state.

And after the door closing state is reached, the power unit is started again and is recovered to the initial state for standby.

In addition, the ejection and rotation integrated door opening and closing device also has an overload protection function. Specifically, when the torque between the driving shaft 51 and the driven shaft 52 is too large, the driving shaft 51 slides in the axial direction to be away from the driven shaft 52, so as to trigger the third trigger 73, and according to a trigger signal sent by the third trigger 73, the power-off protection processing can be performed on the power unit, so that an accident is prevented, and meanwhile, the mechanical structure can be prevented from being damaged. When the torque between the driving shaft 51 and the driven shaft 52 returns to the normal range, the driving shaft 51 and the driven shaft 52 are tightly pressed again under the action of the compression spring 55. Since the maximum distance between the driving shaft 51 and the driven shaft 52 is limited by the housing 2, the two cannot be completely separated, and thus the two are not angularly displaced after being restored to the tight press-fit state.

Example 2

Compared with embodiment 1, the push-out and rotation integrated door opening and closing device provided in this embodiment does not have the third triggering member 73, and the rotation driving member 5 does not adopt a split structure in which the upper and lower portions are elastically press-connected, but adopts an integral structure, as shown in fig. 17.

Therefore, compared to embodiment 1, the push-out and rotation integrated door opening and closing device provided in this embodiment is functionally only omitted from the overload protection function.

The above embodiments are provided for illustrative purposes, so that those skilled in the art can understand the technical idea and features of the present invention and implement the utility model, and the protection scope of the present invention is not limited thereby. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
