Description
Technical Field
[0001] This invention relates to the field of automotive handle accessories, specifically a rotary concealed handle with automatic slow-reset damping and its method of use. Background Technology
[0002] Currently, concealed handles are being widely used due to their advantages such as fitting the streamlined body, reducing wind resistance, and eliminating manual operation. However, existing rotary concealed handles do not have a damping mechanism for slow reset. The handles do not have a buffer when popping out and retracting, which will subject them to high spring force and generate a lot of noise, reducing the user experience. Summary of the Invention
[0003] In order to overcome the shortcomings of the existing technology and provide a handle accessory with simple structure, convenient use and good damping effect, this invention discloses a rotary hidden handle with automatic slow reset damping and its usage method.
[0004] The present invention achieves its objective through the following technical solution: A rotary concealed handle with automatic slow-reset damping includes a concealed handle and a handle cylindrical pin. It is characterized by further comprising a concealed handle pin, a base, a mechanical reset lever pin, a mechanical reset lever, a damping rocker arm pin, a damping rocker arm, a damper mounting screw, a damper, and a torsion spring for the mechanical reset lever. The concealed handle is positioned and installed into the base by the concealed handle shaft pin, so that the concealed handle and the base form a rotational engagement through the concealed handle shaft pin; A mechanical reset lever torsion spring is installed inside the mechanical reset lever. A lever cylindrical pin is provided on the outer edge of the mechanical reset lever. A rocker arm slot is provided at the lower part of the damping rocker arm. One end of the lever cylindrical pin is embedded in the rocker arm slot and the two form a rotary sliding fit. The mechanical reset lever pin is fitted into the mechanical reset lever torsion spring. The mechanical reset lever is positioned and installed into the base by the mechanical reset lever pin fitted with the mechanical reset lever torsion spring, so that the mechanical reset lever and the base form a rotational sliding fit. The other end of the mechanical reset lever is provided with a lever U-shaped groove, which contacts the handle cylindrical pin shaft surface on the hidden handle to form a rotary sliding fit. The damping rocker arm is mounted on the base via a damping rocker arm shaft pin, and the damper is fixed on the base via a damper mounting screw. The damping rocker arm is equipped with a damping rocker arm transmission component, and the damper is equipped with a damper transmission component. The damping rocker arm transmission component and the damper transmission component cooperate with each other to form a rotational dynamic engagement between the damping rocker arm and the damper. The damping rocker arm forms a sliding engagement with the lever cylindrical pin on the outer edge of the mechanical reset lever.
[0005] The rotary concealed handle with a mechanical automatic slow-reset damping mechanism is characterized by: Both the damping rocker arm drive and the damper drive components use gears, sprockets, or pulleys. When both the damping rocker arm drive and the damper drive are made of gears, the damping rocker arm drive and the damper drive mesh with each other. When both the damping rocker arm drive and the damper drive are made of sprockets, the damping rocker arm drive and the damper drive are connected to each other by a chain. When both the damping rocker arm drive and the damper drive are made of belt pulleys, the damping rocker arm drive and the damper drive are connected to each other by belts.
[0006] In this invention: the hidden handle opens the car door; the hidden handle is fixed by a pin; the base fixes all other parts; the mechanical reset lever is fixed by a pin and a torsion spring; the mechanical reset lever connects the hidden handle and the damping rocker arm; the damping rocker arm is fixed by a pin; the damping rocker arm connects the damper and the mechanical reset lever; the damper is fixed by a mounting screw; the damper provides damping for the hidden handle's reset; and the mechanical reset lever torsion spring provides the restoring force for the hidden handle's reset.
[0007] The method of using the rotary concealed handle with a mechanical automatic slow-reset damping mechanism is characterized by including pop-out and retraction: Pop-up: When the retracted hidden handle receives a pop-up command, the mechanical reset lever rotates forward, tightening the mechanical reset lever torsion spring. When the mechanical reset lever rotates forward, on the one hand, the lever's cylindrical pin drives the damping rocker arm and its transmission components to rotate through the rocker arm slot. The damping rocker arm transmission components then drive the damper transmission components and the damper itself to rotate, with the damper damping and slowing down the rotation. On the other hand, the lever's U-shaped groove actuates the handle's cylindrical pin, thereby popping the hidden handle out. Retraction: When the retracted handle is in the pop-up state, the mechanical reset lever torsion spring, under the action of the restoring force, drives the mechanical reset lever to rotate in the opposite direction. When the mechanical reset lever rotates in the opposite direction, on the one hand, the lever's cylindrical pin drives the damping rocker arm and damping rocker arm transmission component to rotate through the rocker arm slot. The damping rocker arm transmission component drives the damper transmission component and damper to rotate, and the damper plays a damping and slowing role in the rotation. On the other hand, the lever's U-shaped groove moves the handle's cylindrical pin, thereby driving the retracted handle.
[0008] This invention solves the problems of large impact force, high noise, and reduced service life caused by the lack of damping during the reset of current rotary concealed handles. It has the following beneficial effects: simple structure, convenient use, good damping effect, extended handle life, and improved user experience. Attached Figure Description

Figures 1-4 As shown, the specific structure is: The hidden handle 1 is provided with a handle cylindrical pin 11. The hidden handle 1 is positioned and installed into the base 3 by the hidden handle pin 2, so that the hidden handle 1 forms a rotational engagement with the base 3 through the hidden handle pin 2 and the base 3. The mechanical reset lever torsion spring 10 is installed inside the mechanical reset lever 5. The outer edge of the mechanical reset lever 5 is provided with a lever cylindrical pin 51. The lower part of the damping rocker arm 7 is provided with a rocker arm slot 71. One end of the lever cylindrical pin 51 is embedded in the rocker arm slot 71 and the two form a rotary sliding fit. The mechanical reset lever pin 4 is fitted into the mechanical reset lever torsion spring 10. The mechanical reset lever 5 is positioned and installed into the base 3 by the mechanical reset lever pin 4 fitted with the mechanical reset lever torsion spring 10, so that the mechanical reset lever 5 and the base 3 form a rotational sliding fit. The other end of the mechanical reset lever 5 is provided with a lever U-shaped groove 52, which contacts the handle cylindrical pin 11 on the hidden handle 1 to form a rotary sliding fit. The damping rocker arm 7 is mounted on the base 3 via the damping rocker arm shaft pin 6, and the damper 9 is fixed on the base 3 via the damper mounting screw 8. The damping rocker arm 7 is provided with a damping rocker arm transmission component 72, and the damper 9 is provided with a damper transmission component 91. The damping rocker arm transmission component 72 and the damper transmission component 91 cooperate with each other to form a rotational dynamic engagement between the damping rocker arm 7 and the damper 9. The damping rocker arm 7 forms a sliding engagement with the lever cylindrical pin 51 on the outer edge of the mechanical reset lever 5.
[0012] Both the damping rocker arm drive component 72 and the damper drive component 91 are made of gears, sprockets, or pulleys. When both the damping rocker arm drive component 72 and the damper drive component 91 are made of gears, the damping rocker arm drive component 72 and the damper drive component 91 mesh with each other. When both the damping rocker arm drive component 72 and the damper drive component 91 are made of sprockets, the damping rocker arm drive component 72 and the damper drive component 91 are connected to each other by a chain. When both the damping rocker arm drive component 72 and the damper drive component 91 are made of belt pulleys, the damping rocker arm drive component 72 and the damper drive component 91 are connected to each other by belts.
[0013] In this embodiment: when both the damping rocker arm transmission component 72 and the damper transmission component 91 are gears, the damping rocker arm transmission component 72 and the damper transmission component 91 mesh with each other. In this embodiment: the hidden handle 1 opens the door; the hidden handle pin 2 fixes the hidden handle 1; the base 3 fixes all other parts; the mechanical reset lever pin 4 fixes the mechanical reset lever 5 and the mechanical reset lever torsion spring 10; the mechanical reset lever 5 connects the hidden handle 1 and the damping rocker arm 7; the damping rocker arm pin 6 fixes the damping rocker arm 7; the damping rocker arm 7 connects the damper 9 and the mechanical reset lever 5; the damper mounting screw 8 fixes the damper 9; the damper 9 provides reset damping for the hidden handle 1; and the mechanical reset lever torsion spring 10 provides the restoring force for the reset of the hidden handle 1.
[0014] When used in this embodiment, it includes popping up and retracting: Pop-up: When the retracted hidden handle 1 receives a pop-up command, the mechanical reset lever 5 rotates forward, tightening the mechanical reset lever torsion spring 10. When the mechanical reset lever 5 rotates forward, on the one hand, the lever cylindrical pin 51 drives the damping rocker arm 7 and the damping rocker arm transmission component 72 to rotate through the rocker arm slot 71. The damping rocker arm transmission component 72 drives the damper transmission component 91 and the damper 9 to rotate. The damper 9 dampens and slows down the rotation. On the other hand, the lever U-shaped groove 52 moves the handle cylindrical pin 11, thereby causing the hidden handle 1 to pop out. To manually operate the hidden handle Figure 1 and Figure 3 Part A in the diagram refers to the location where you press the hidden handle. Retraction: When the hidden handle 1 is in the pop-up state and receives a retraction command, the mechanical reset lever torsion spring 10, under the action of restoring force, drives the mechanical reset lever 5 to rotate in the opposite direction. When the mechanical reset lever 5 rotates in the opposite direction, on the one hand, the lever cylindrical pin 51 drives the damping rocker arm 7 and the damping rocker arm transmission component 72 to rotate through the rocker arm slot 71. The damping rocker arm transmission component 72 drives the damper transmission component 91 and the damper 9 to rotate. The damper 9 plays a damping and slowing role on the rotation. On the other hand, the lever U-shaped groove 52 moves the handle cylindrical pin 11, thereby driving the hidden handle 1 to retract.
