Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a semi-concealed fixed door handle assembly. Background Technology

[0002] In the current automotive technology field, exterior door handles are mainly of two types: fully exposed and concealed. Fully exposed exterior door handles, because they protrude from the vehicle's surface during driving, increase wind resistance, thus affecting fuel economy, and are also aesthetically unappealing. Furthermore, long-term exposure to the external environment makes them susceptible to corrosion from rain, dust, sand, etc., affecting not only appearance but also potentially reducing the handle's lifespan and operational performance.

[0003] While concealed exterior door handles improve wind resistance to some extent, they have several structural design shortcomings. For example, their transmission mechanisms are often complex, involving the coordinated operation of multiple electrical and mechanical components. This not only increases manufacturing costs but also makes them prone to malfunctions, reducing the handle's reliability. Furthermore, the seal between the handle and the vehicle body is difficult to guarantee during handle movement, allowing rainwater and dust to easily enter the door through gaps, damaging critical components such as electronic circuits and door locking mechanisms, thus affecting the vehicle's normal operation.

[0004] Meanwhile, traditional exterior door handles require users to manually pull the handle to open the door, which is inconvenient. Furthermore, concealed handles are susceptible to external interference in signal transmission, leading to unstable unlocking and locking signals, which affects vehicle safety and user experience. Utility Model Content
