Description

Technical Field

[0001] This application belongs to the technical field of door handles, and particularly relates to a door handle. Background Art

[0002] A door lock is a device used to lock a door to prevent others from opening it. Such a device may be mechanical or electric. Electric ones require electrical energy. Generally, a handle is installed on the door lock so that a person can hold the handle to open and close the door.

[0003] The existing Chinese patent with the publication number CN105370095B discloses a handle mechanism for driving a lock module to actuate. The handle mechanism has a housing, a handle, a linkage, and a transmission rod. The linkage selectively couples the handle and the transmission rod. When the linkage does not couple the handle and the transmission rod, the handle cannot drive the lock module to actuate through the transmission rod, so as to avoid damage to the lock module caused by improper force applied to the handle. On the contrary, when the linkage couples the handle and the transmission rod, the handle can drive the lock module to actuate through the transmission rod.

[0004] Although the above-mentioned handle mechanism can avoid damage to the lock, the external convex mounting structure of the door handle makes the external convex door handle prone to hitting the human body accidentally and causing injuries, and improvements are made to this. Utility Model Content

[0005] The purpose of this application is to provide a door handle for the above-mentioned existing technical problems, so that when not in use, the door handle can be retracted to make it not easy to injure the human body.

[0006] This application provides a door handle, including a lock and a door handle assembly installed on the lock. The door handle assembly includes:

[0007] A connecting rod, connected to the lock;

[0008] A handle member, movably connected to the connecting rod;

[0009] A rotating member, movably installed on the connecting rod;

[0010] A driving mechanism for driving the rotating member to rotate, and the driving mechanism is installed on the connecting rod;

[0011] Wherein, the connecting rod is provided with a chute wound around the outer surface, the handle member is provided with a sliding portion corresponding to the chute, the rotating member is provided with a limiting portion, and the handle member is provided with a limiting groove corresponding to the limiting portion.

[0012] The connecting rod is hinged to the rotating member. The rotating member is sleeved on the connecting rod and can rotate around the axis of the connecting rod. The structure between the limiting portion and the limiting groove enables the rotating member and the handle member to move along the axis of the rotating member. The connecting rod is movably connected to the handle member. The sliding groove cooperates with the sliding portion. When the rotating member rotates, the handle member rotates around the axis of the connecting rod and the sliding portion moves in the sliding groove. At the same time, the handle member moves along the axis of the connecting rod through the sliding groove, causing the handle member to rotate and protrude outward. When the sliding portion moves to the end of the sliding groove, the handle member is in a retracted or protruding state. When the handle member protrudes, the connecting rod rotates by rotating the handle member, thereby realizing the opening of the lock. The door handle rotates into a convex state when opening the door is needed and is in a retracted state under normal conditions. When the connecting rod and the handle member rotate, the connecting rod and the lock do not rotate and open.

[0013] Further, the driving mechanism includes:

[0014] A driving motor;

[0015] A first gear mounted on the driving shaft of the driving motor;

[0016] A second gear connected to the rotating member;

[0017] Wherein, the connecting rod is provided with a connecting portion, and the driving motor is mounted on the connecting portion.

[0018] The driving motor is connected to the power supply and the controller. The rotation of the driving motor controls the rotation of the first gear. The first gear meshes with the second gear, and the second gear is fixedly connected to the rotating member, thereby realizing the rotation of the rotating member around the axis of the connecting rod. The driving motor is mounted on the connecting portion, and the connecting portion is fixedly connected to the connecting rod, ensuring the structural stability of the driving mechanism.

[0019] Further, the lock includes:

[0020] An outer housing mounted on the door body;

[0021] A first groove disposed on one side of the outer housing and corresponding to the handle member.

[0022] The outer housing is mounted on the door body. When the handle member is retracted, the handle member cooperates with the first groove to retract, improving the overall structural compactness after the handle member is retracted.

[0023] Further, a second groove is provided on one side of the handle member.

[0024] The second groove is disposed on one side of the handle member, and when the handle member is retracted, the second groove is close to the edge of the outer housing. A gap is formed between the first groove and the second groove, facilitating pulling when closing the door.

[0025] Further, a switch button is provided on the handle member, and the axis of the switch button is the same as the axis of the connecting rod.

[0026] The switch button adopts a pressure sensor or a thermal induction sensor. The switch button is connected to a power supply, a controller, etc., and controls the driving motor to work through the switch button, so that the handle member can rotate and protrude.

[0027] Further, the handle member is provided with an installation cavity, and a heating module installed in the installation cavity is provided on the handle member.

[0028] The heating module is installed in the installation cavity. When the weather is cold, the temperature of the handle member is increased through the heating module during the rotation of the handle member, improving the comfort of holding the handle member when opening the door. The heating module is connected to a power supply, a controller, etc.

[0029] The beneficial effects of this application are:

[0030] 1. When the rotating member rotates, the handle member rotates around the axis of the connecting rod and the sliding portion moves in the sliding groove, and at the same time, the handle member moves along the axis of the connecting rod through the sliding groove, so that the handle member rotates and extends outwards.

[0031] 2. When the sliding portion moves to the end of the sliding groove, the handle member is in a retracted or protruding state. When the handle member protrudes, the sliding portion abuts against the end of the sliding groove, and the connecting rod rotates by rotating the handle member, thereby realizing the opening of the lock.

[0032] 3. The first groove is convenient for accommodating the handle member when it is retracted, and the cooperation of the first groove and the second groove is convenient for pulling the door body to rotate when the handle member is retracted. Description of the Drawings
