[0001] DESCRIPTION

[0002] A SLIDING DOOR SYSTEM

[0003] Technical Field

[0004] The present invention relates to a sliding door system which enables doors to be opened and closed by providing pushing forward or pulling backward movements of sliding doors with the use of a magnetomechanical actuator.

[0005] Background of the Invention

[0006] Sliding door systems are used for opening the doors of vehicles and are manually released from the lock part first and then pushed back manually to perform the opening or closing of the door. Today, the opening and closing functions of vehicle sliding doors can be performed both manually and automatically. For automatic sliding door systems, the opening and closing functions can be performed by pulling the sliding door back or pushing it forward via an actuator.

[0007] The manual sliding door mechanisms used today are suitable for adult use, especially in service vehicles, however, in cases where children of certain age groups are pushing or pulling them in school services, door weight and mechanical friction are a problem when safety is also taken into consideration. In particular, either the child's strength is not enough to push or pull the door, or the child pushes the door on the one hand and does not keep his / her hand away from the door on the other, causing injuries due to jamming. For the solution of this problem, today, automatic sliding door systems can be operated under the control of the vehicle driver with a supervision that allows the door to open and close. However, in order to prevent injuries and accidents that may occur in the doorway with electronic security measures, emergency stop, and release functions are also required with the relevant sensors. This situation has an adverse effect byincreasing the complexity of the system, validation, testing and product cost considerably. For this reason, today, there is a need for a solution that enables sliding doors to be opened by overcoming the aforementioned problems.

[0008] The South Korean patent document no. KR20100001951U, an application included in the state of the art, discloses a mechanism which can semi-automatically open and close a sliding door panel for vehicles backward and forward. The invention relates to a sliding door and its upper part, to which is attached a sliding door panel that can slide back and forth along its side outer surface with respect to an opening mounted on the side of a car body or container. Part of the door panel is provided with a sliding door panel. An upper roller support receiving rail fixed to the inner upper part of an upper slide rail, with one end fixed to the upper part, the other end bent inwards and one side open outwards, is perpendicular to the inner lower part. An upper support element slidably supported by means of an upper roller arrangement consisting of a plurality of supported rollers is fixedly placed, and one end thereof is fixed to the lower right and left sides of the door panel on both sides of the sliding door panel, and the other end thereof is bent inwards and one side is open outwards, and the first and second lower roller support receiving rails are fixed to the inner upper part of the first and second lower sliding rails and the first and second lower sliding rails. The first and second lower support elements are configured to be fixedly arranged to be slidably supported by means of the first and second lower roller arrangements consisting of a plurality of first and second lower rollers supported at perpendicular angles to each other on the inner lower surface.
