[0013] Fourthly, this application provides an automobile, including the aforementioned type of door.
[0014] The present invention provides a rotary handle, door lock handle, car door, and car for automobiles, which has the following beneficial effects:
[0015] (1) This application designs a novel handle that creatively uses a rotary knob to open and close the door lock. On the one hand, in the existing door locks, the pull cord is wound in a "circular" shape. In this application, the pull cord is wound around a winding post that is fixedly connected to the knob. The rotary knob drives the winding post to rotate synchronously through the first base plate, and the pull cord is wound or unwound at the same time, thereby unlocking or locking the door lock. Therefore, the existing door lock and the handle of this application can fit together perfectly. On the other hand, since the unlocking or locking process of the handle of this application is completed by rotation, the lateral inertia resistance can be well guaranteed. There is no need to design a Y-direction inertia resistance balance block, which helps to reduce costs.
[0016] (2) A sealing ring is provided on the inner side of the first base plate, which helps to improve the aesthetics and sealing performance in the locked state; by designing the connecting rod and the connecting hole as a threaded connection, the connecting rod is driven to rotate in the connecting hole during the rotation of the knob, so that the first base moves stably closer to the second base, and the sealing ring is moved away from the inner side of the outer panel of the door to prevent excessive friction; by setting the slider and the compression spring, the connecting rod drives the slider to move towards the second base plate during the rotation of the knob, so that the torsion spring is torn and compressed, and the compression spring is compressed, which helps to restore the connecting rod and the slider to the locked state under the action of the torsion spring and the compression spring when the knob is released.
[0017] (3) This application does not restrict the shape of the knob, so the knob can be made into a variety of round and cute appearances based on a circular base to meet the requirements of the shape. Attached Figure Description
