The present application claims priority to the Chinese Patent Application No. 201911156862.2, filed to the Chinese Patent Office on Nov. 22, 2019, and entitled “Mounting mechanism for hidden vehicle door handle and vehicle”, the entire contents of which are incorporated herein by reference.
The application relates the technical field of vehicles and, more particularly, to a mounting mechanism for a hidden vehicle door handle and a vehicle comprising the mounting mechanism for the hidden vehicle door handle.
Vehicle door handles are used for opening vehicle doors, some of the vehicle door handles are designed in a hidden manner in consideration of beauty and to reduce the wind resistance coefficient, in another word, the vehicle door handles automatically stretch out after the vehicle doors are unlocked to be used for opening the vehicle doors by passengers, and the handles are automatically hidden inside the vehicle doors when vehicles start to run, thereby reducing the wind resistance and the oil consumption and facilitating energy conservation and emission reduction. The hidden vehicle door handles are also provided with protective handles, so that the handles are prevented from being exposed out of vehicle door metal plates, so that the handles are prevented from being eroded by burning sun, wind and rain, etc.
It is required that handles are mounted on vehicle door outer plate reinforcing plates on the aspect of strength, and the handles and vehicle door outer plates on the peripheries of the handles have uniform gaps and flushes on the aspect of appearance attractiveness, this requires that handle assemblies may be adjusted according to appearances during mounting. At present, handle bases are usually directly connected to mounting holes in vehicle door outer plate reinforcing plates by bolts so that gaps between the handles and the vehicle door outer plates on the peripheries of the handles may be adjusted by the handle mounting holes. However, uniform flushes between the handles and the vehicle door outer plates may not be ensured due to a relatively large assembly error and unavailable flush adjustment in a bolt connection manner, and uniform gaps between the handles and the vehicle door outer plates are also hardly ensured in a limit state due to limited adjustment amounts of the handle mounting holes.
