Description

Technical Field

[0001] The utility model belongs to the technical field of automobile door handles and relates to a swing-out mechanism of a hidden door handle. Background Art

[0002] The hidden door handles of cars are widely used because the handles are flush with the outer surface of the door, which is more in line with the requirements of streamlined car bodies and more beautiful. The hidden door handles are hidden under the gold-plated outer surface of the door and require an electric opening device to push the door handles out.

[0003] For example, a Chinese patent discloses a hidden external handle electric pre-opening device [authorization announcement number CN220580787U]. When working, the connecting shaft of the actuator extends to drive the push block to move linearly. The push block moves to a predetermined position to squeeze the raised inclined surface of the handle, driving the handle component to rotate around the handle axis, so that one side of the handle component moves out of the hidden groove.

[0004] In actual use, since the push block is located on the side of the handle component, the push block will cause the handle component to deviate from its original position when pushing the handle component. That is, the end of the handle component away from the handle axis will deflect toward the side away from the push block, causing the handle component to loosen and the stability to deteriorate, failing to meet the use requirements. In severe cases, the handle component may be damaged. Utility Model Content

[0005] The utility model aims to solve the above problems in the prior art and proposes a swing-out mechanism for a hidden door handle which will not cause the handle to deviate.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] The swing-out mechanism of the hidden door handle is arranged in the door body of the vehicle door. A accommodating groove is arranged on the outer side of the door body. A door handle is rotatably installed in the accommodating groove through a rotating shaft. The door handle is provided with an acting part extending into the inner side of the door body. The swing-out mechanism includes an actuator arranged on the inner side of the door body and a rotating block rotatably arranged on the inner side of the door body. The rotation center line of the rotating block is parallel to the rotating shaft. The electric push rod of the actuator acts on one side of the rotating block. The acting part is located on the other side of the rotating block and can be pushed by the rotating block.

[0008] The internal space of the door body is limited, and the actuator and the action part are usually staggered, that is, the electric push rod of the actuator is located on the side of the action part, and the electric push rod cannot act directly on the action part. Since a rotatable rotating block is set between the electric push rod and the action part, the rotating block pushes the action part from the rear of the action part during pushing, and the door handle will not deviate from the original position.

[0009] In the swing-out mechanism of the hidden door handle, the rotating block is rotatably mounted on the inner side of the door body via the rotating shaft, that is, the rotating block and the door handle share a rotating shaft, so the door handle and the rotating block can be installed at the same time, which can effectively improve the installation efficiency.

[0010] In the swing-out mechanism of the above-mentioned hidden door handle, the inner side of the door body is provided with a first mounting groove located on one side of the accommodating groove and a second mounting groove located on the other side of the accommodating groove, the rotating shaft is simultaneously passed through the first mounting groove, the accommodating groove and the second mounting groove, the rotating block has a first extending portion extending into the first mounting groove and a second extending portion extending into the second mounting groove, the first extending portion and the second extending portion are rotatably sleeved on the rotating shaft.

[0011] A first mounting hole for installing a rotating shaft is provided on the door body, a second mounting hole is provided on the door handle, and a third mounting hole is provided on the first extension portion and the second extension portion respectively. During installation, the door handle is placed in the accommodating groove, the first extension portion is extended into the first mounting groove, and the second extension portion is extended into the second mounting groove, so that the first mounting hole, the second mounting hole and the third mounting hole are coaxial, and then the rotating shaft is inserted from one end of the first mounting hole, and passes through the second mounting hole, the first mounting hole located in the middle and the third mounting hole in sequence, and then passes through the other end of the first mounting hole, and the position of the rotating shaft is locked by fasteners, which is convenient for installation.

[0012] The first mounting groove and the second mounting groove can limit the axial position of the rotating block.

[0013] In the above-mentioned swing-out mechanism of the hidden door handle, a pushing block is connected to the electric push rod of the actuator, and the rotating block has a first pushing surface. The end of the pushing block away from the actuator is in linear contact with the first pushing surface, and the contact line is parallel to the rotating shaft.

[0014] The pushing block is in line contact with the first pushing surface, which can reduce friction and noise between the two while ensuring the pushing effect. The angle between the pushing direction of the pushing block and the first pushing surface is an acute angle, and the angle becomes smaller and smaller as the pushing proceeds.

[0015] In the above-mentioned swing-out mechanism of the hidden door handle, the contact point between the pushing block and the first pushing surface has a first arc surface, and the first arc surface is in line contact with the first pushing surface.

[0016] In the above-mentioned swing-out mechanism of the hidden door handle, a guide seat is provided on the door body, a guide hole is provided in the guide seat, and the push block is slidably disposed in the guide hole.

[0017] In the above-mentioned swing-out mechanism of the hidden door handle, the action part has a second pushing surface parallel to the axis of the rotating shaft, and the rotating block has a second arc surface in line contact with the first pushing surface, and the contact line between the second arc surface and the second pushing surface is parallel to the rotating shaft.

[0018] Compared with the prior art, the swing-out mechanism of the hidden door handle has the following advantages:

[0019] A rotatable rotating block is arranged between the electric push rod and the acting part. When pushing, the rotating block pushes the acting part from directly behind the acting part, and the door handle will not deviate from the original position; the rotating block and the door handle share a rotating shaft, which can effectively improve the installation efficiency; the pushing block is in line contact with the rotating block, and the acting part is in line contact with the rotating block, which can reduce friction and noise while ensuring the pushing effect.
