Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a damping device for an upward-flipping automobile handle. Background Art

[0002] The existing car door handle is turned to open on the car door. When the car door is opened, the handle is turned to open on the car door. When the car door is closed, the handle is turned to close on the car door. For example, Chinese Patent No. ZL202220797113.9 discloses a car exterior door handle, including a base, a door handle, a lever, and a rotary motor. The door handle is hinged in a groove at the front end of the base through a fixed shaft. A torsion spring is sleeved on the fixed shaft. The two ends of the torsion spring are respectively connected to the door handle and the base. The lever abuts the door handle. The rotary motor can drive the lever to move and then rotate the door handle around the fixed shaft. The door handle adopts a hidden design. It is embedded in the base when not in use. It has a beautiful appearance and is not easy to damage. When it is needed to open the car door, the user touches the door handle lightly, and one end of the door handle will pop out slightly, which is convenient for the user to grasp the door handle. The overall structure is simple and does not take up too much space. There is no damping and buffering structure between the door handle and the base, and due to the force of the torsion spring, the elastically opened door handle lacks a buffering opening structure when opened, resulting in an abnormal noise when the door handle is opened. Alternatively, some handles are reset and closed by a torsion spring after being opened, but due to the lack of a buffering closing structure, an abnormal noise is made when the door handle is reset and closed, and the closing speed is too fast. Utility Model Content

[0003] The purpose of the utility model is to provide a damping device for a flip-up automobile handle, wherein a damping assembly is provided between a bracket and the handle, and the handle is at least closed on the bracket in a damping manner through the damping assembly, so as to prevent the handle from closing quickly on the bracket when closing, avoid collision between the handle and the bracket, and avoid abnormal noise when the handle is closed.

[0004] A damping device for a flip-up automobile handle designed for this purpose includes a damping assembly arranged between a bracket and the handle. The handle is rotatably connected to the bracket, and the handle is rotated to open and close on the bracket. The handle is at least closed on the bracket in a damped rotation manner through the damping assembly, so as to prevent the handle from closing quickly on the bracket when closing, avoid collision between the handle and the bracket, and avoid abnormal noise when the handle is closed.
