Description

P130036NL00 Title: Automatic calibration and locking device for sliding door

The two fixed door leaves are respectively fixed at two ends of the square frame. The two slideable door leaves can slide on the guide rails. In actual applications, the sliding door needs to be locked. An existing lock of the sliding door is generally a movable lock. When the slideable door leaf is pushed or pulled to a position, the movable lock is placed on the guide rail in a way of being next to the slideable door leaf, thus achieving locking.

The first accommodation slot 3 and the second accommodation slot 4 may be in a cuboid shape. In actual applications, the housing 1 may be disposed at a position at the center line of the doorframe of the sliding door, may be an upper frame of the doorframe, or may be a lower frame of the doorframe. A size of the housing 1, a size of the first accommodation slot 3, and a size of the second accommodation slot 4 may be designed according to actual use. The housing 1, being fixed at a position at the center line of the doorframe, may be configured to detect whether a position where two slideable door leaves of the sliding door are joined stays at a position at the center line.

The first primary lock catch 5 is rotatablely disposed within the first accommodation slot 3. The second primary lock catch 6 is rotatablely disposed within the second accommodation slot 4. Refer to FIG. 4, FIG. 4 is a schematic structural diagram of a first primary lock catch 5 and a second primary lock catch 6 according to the application.

It may be learned from FIG. 4 that the first primary lock catch 5 may include a first rotating shaft 51 and a first locking component 52. The first rotating shaft 51 and the first locking component 52 may be respectively disposed at two ends of the first primary lock catch 5. The first primary lock catch 5 may further include a first locking groove 53. The first locking groove 53 may be disposed at one end of the first primary lock catch 5 that is close to the first locking component 52.

By using the second rotating shaft 61, the second primary lock catch 6 may be rotated out from the second accommodation slot 4. When locking is not required, the first primary lock catch 5 and the second primary lock catch 6 are rotatable, which makes the first primary lock catch 5 be able to be disposed within the first accommodation slot 3, and makes the second primary lock catch 6 be able to be disposed within the second accommodation slot 4.

In actual applications, a distance from the transmitting end 21 to the first sensing end 22 and a distance from the transmitting end 21 to the second sensing end 23 are obtained to calculate a distance difference between the two distances. When the distance difference is zero, it indicates that the position where the two slideable door leaves are joined coincides with the center line of the doorframe, which avoids a case that a gap exists between the slideable door leaf and a fixed door leaf during a process of sliding the slideable door leaf in actual applications. A method for obtaining the distance may be selected according to actual requirements. For example, the transmitting end 21 may emit infrared rays, and the first sensing end 22 and the second sensing end 23 may receive the infrared rays. The distance is measured through the infrared rays. A specific manner is not defined in the application.
