Description

Technical Field

[0001] The present application relates to the technical field of hidden handles, and in particular, to a flat-out mechanical hidden handle. Background Art

[0002] Car handles can be roughly divided into two types: hidden handles and non-hidden handles. Under normal circumstances, hidden handles are retracted into the groove of the car door to reduce resistance during driving, and the handle is extended when the door is opened. In the prior art, hidden handles are divided into electric hidden handles and mechanical hidden handles. Electric hidden handles use a key or a sensor on the handle to control the operation of its internal motor. The motor drives the internal drive assembly to operate, so that the handle can be rotated out or flattened to unlock. It has the characteristics of intelligence and technology, but the structure is complex and expensive. Mechanical hidden handles are screw-out handles, that is, the operator needs to press one end of the handle with one hand to make the handle rotate outward and tilt outward, and then hold the handle with the other hand to unlock. The operating space between the handle and the car door after it is rotated out is small, which is not conducive to the operator's hand reaching in, resulting in inconvenience for the operator and detrimental to ergonomics.

[0005] Preferably, the damper assembly includes a damper fixedly connected to the inner wall of the base; the damper includes a first tooth, and a second tooth is provided at the second end of the fourth arm, the first tooth and the second tooth meshing with each other. The above technical solution discloses a specific structure of the damper assembly. During the pressing process, the second tooth rotates on the damper, and during the ejection process, the second tooth cooperates with the damper to limit the speed at which the rear swing arm returns to its original position.

[0006] Preferably, the damping assembly also includes a damping swing arm, which includes a damping swing arm body, a second tooth and a toggle block; a third shaft is rotatably connected to the damping swing arm body, the third shaft is fixedly connected to the inner wall of the base, a third torsion spring is sleeved on the third shaft, and the two ends of the third torsion spring are respectively connected to the inner wall of the base and the damping swing arm body; the second tooth and the toggle block are both fixedly connected to the side of the damping swing arm body, and when the handle is in the pressing process, the second end of the fourth arm overlaps with the first side of the toggle block; when the handle is in the popping-out process, the second end of the fourth arm overlaps with the second side of the toggle block. Since the second tooth is directly designed to cooperate with the damper on the second arm, the speed limiting effect on the reset of the rear swing arm is small. Through the above technical solution, a damping swing arm is designed between the fourth arm and the damper. During the pressing process, the rear swing arm rotates, causing the fourth arm to toggle the toggle block, driving the damping swing arm to rotate. During the pop-up process, the second tooth cooperates with the damper to limit the reset speed of the damping swing arm, thereby limiting the reset speed of the fourth arm, which helps to reduce the reset speed of the rear swing arm during the pop-up process.

[0007] Preferably, a roller is rotatably connected to the second end of the fourth arm. When the handle is in the pressing and ejecting stages, the roller is in rolling connection with the second end of the fourth arm and the first and second side surfaces of the toggle block, respectively.

Through the above technical solution, on the one hand, the depth of the first end of the handle extending into the base is limited during the pressing process; on the other hand, the fourth spring accumulates force during the pressing process, and during the ejection process, the fourth spring drives the stopper to return to its original position, causing the stopper to push the first end of the handle body, thereby increasing the force applied to the first end of the handle body during the ejection process.

[0010] Preferably, the end of the second shaft is fixedly connected to the bottom surface of the inner wall of the base; a fifth shaft is provided on the fourth arm, the end of the fifth shaft is fixedly connected to the top surface of the inner wall of the base, and the axis of the fifth shaft coincides with the axis of the second shaft.

[0011] Preferably, an inertia lock is provided on the rear swing arm body, and the inertia lock is rotatably connected between the rear swing arm body and the inner wall of the base.

[0012] Preferably, the zipper swing arm includes a zipper swing arm body, a connecting arm and a shift rod; the zipper swing arm body is rotatably connected to the sixth shaft, the sixth shaft is fixedly connected to the inner wall of the base, the sixth shaft is sleeved with a sixth torsion spring, and the two ends of the sixth torsion spring are respectively connected to the zipper swing arm body and the inner wall of the base; the connecting arm and the shift rod are both fixedly connected to the zipper swing arm body, the connecting arm is used to be fixedly connected to the first end of the pull wire, and when the handle is in the unlocked state, the shift rod overlaps with the rear swing arm body.

[0013] Preferably, it further comprises a lock core and a pull wire, the lock core is fixedly connected to the inside of the base, and the second end of the pull wire is fixedly connected to the lock core.

When the first end of the handle body is pressed, the second end of the handle body is lifted up and extends out of the base, driving the rear swing arm to rotate, and the second arm of the rear swing arm drives the connecting rod to move toward the second end of the base, thereby driving the second front swing arm to rotate around the first axis, so that the first torsion spring accumulates force; by designing a damping component, that is, a damping swing arm and a damper are designed near the fourth arm of the rear swing arm, the rear swing arm rotates and activates the toggle block through its fourth arm, driving the damping swing arm to rotate. During the pop-up process, the second tooth cooperates with the damper to limit the speed of the damping swing arm's reset, so that under the action of the first torsion spring, the first connecting arm rotates to push the first end of the handle body out of the base, thereby realizing the horizontal extension of the handle body; by designing a fixing column and a second torsion spring on the connecting rod, the retraction and hiding of the handle body is realized.
