Technical Field
[0001] This utility model relates to the field of automotive parts, and more particularly to automotive door handles, specifically an emergency exterior door handle device for automobiles with both electric and mechanical functions. Background Technology
[0002] Currently, concealed door handles are becoming increasingly common in the automotive industry, especially in the field of new energy vehicles, where they are favored by automakers due to their technological appeal and reduced wind resistance. However, this design has also exposed many problems, including shortcomings in safety, environmental adaptability, and maintenance costs.
[0003] Concealed car door handles mainly fall into the following types: Electric pop-out type: It pops out automatically through a motor, which is technologically advanced, but it relies on an electronic system.
[0004] Press-type lever concealed type: The front end needs to be pressed to make the back part pop up, which is slightly complicated to operate and is prone to freezing in winter.
[0005] Semi-concealed: Retains some mechanical structure, balancing aesthetics and practicality.
[0006] Handleless design: Relies entirely on electronic systems, making it difficult to operate.
[0007] The above-mentioned product types typically have the following technical defects: (1) Security issues Power failure: In the event of a collision or battery fire, the electronic system may malfunction, preventing the doors from opening and delaying escape or rescue.
[0008] The rescue is difficult because firefighters or emergency responders have difficulty quickly identifying and operating the concealed handle in an emergency.
[0009] Lack of standardized markings: The emergency mechanical handles on some models are in concealed locations and not standardized, increasing the difficulty of operation.
[0010] (2) Poor adaptability to extreme environments Winter freezing problem: In cold northern regions, door handles are easily frozen by ice and snow, making them unable to pop out or retract.
[0011] High temperature / humidity environment effects: Motors or electronic components may be damaged by extreme weather, increasing the failure rate.
[0012] (3) High maintenance costs Electronic components are easily damaged: Components such as motors and sensors may wear out or malfunction after long-term use, and the repair costs are much higher than those of traditional mechanical handles.
[0013] Complex structure: Disassembly and assembly require professional skills, which are difficult for ordinary repair shops to handle, increasing the maintenance costs for car owners.
[0014] (4) Poor user experience High learning curve: Some users are not familiar with how to open the hidden handle, leading to accidental operation 38.
[0015] Reliability controversy: Some car manufacturers sacrifice practicality in pursuit of "technological sophistication," such as the complicated door opening logic of some models (requiring pressing before sliding).
[0016] Therefore, concealed door handles offer advantages in enhancing vehicle aesthetics and aerodynamic performance, but issues such as safety, environmental adaptability, and maintenance costs still need to be addressed. As industry standards continue to improve and automakers make technological advancements, achieving a better balance between safety and practicality with concealed door handles is a current industry challenge that those skilled in the art need to consider.

[0036] 1. Emergency handle cover 2 Door lock pull rope 3 Emergency actuator 4. Rotation axis 5. Elastic components Detailed Implementation
[0037] To more clearly describe the technical content of this utility model, the following description is provided in conjunction with specific embodiments.
[0038] Before describing the embodiments according to the present invention in detail, it should be noted that, in the following, the terms “comprising,” “including,” or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed or inherent to such process, method, article, or apparatus.
[0039] Please see Figures 1 to 6 As shown, this automotive emergency exterior door handle device has both electric and mechanical functions, wherein the device includes: Emergency handle cover 1 is located at the top of the device, with one end connected to the rotary reset structure and connected to the emergency actuator 3 via a connecting shaft; The door lock pull rope 2 is connected to the door lock at the lower end and is exposed from above when the emergency handle cover 1 is opened. In an emergency, the emergency handle cover 1 is popped open from above by the rotating reset structure or the emergency actuator 3, exposing the door lock pull rope 2, which then unlocks the car door.
[0040] Please see Figure 3 As shown, in a preferred embodiment of the present invention, when the emergency handle cover 1 is not opened, the door lock pull rope 2 is in a tightened state inside the emergency handle cover 1.
[0041] In a preferred embodiment of the present invention, the rotary reset structure includes a rotary shaft 4 and an elastic component 5, wherein the elastic component 5 is wound and fixed on the rotary shaft 4.
[0042] In a preferred embodiment of this utility model, the elastic component 5 is a spring.
[0043] In a preferred embodiment of this utility model, when the rotary reset structure is in the initial position, the emergency handle cover 1 is in a closed state. In a preferred embodiment of this utility model, in an emergency, when the emergency handle cover 1 is pulled, causing the rotary reset structure to begin rotating clockwise / counterclockwise along the rotation axis 4 (the direction of rotation is defined as clockwise when viewed from outside the vehicle to inside, and counterclockwise when viewed from the opposite direction), the elastic component 5 generates a compressive force and causes the emergency handle cover 1 to spring open. At the instant the emergency handle cover 1 springs open, the door lock pull rope 2, which was previously in a tightened state, is exposed from within the emergency handle cover 1. In this configuration, by pulling / pushing upwards, after the latch of the emergency handle cover 1 disengages from the output shaft of the emergency actuator 3, the emergency handle cover 1 springs open from above under the force of the rotary reset structure, thus opening the door.
[0044] In a preferred embodiment of this utility model, after the door lock pull cord 2 unlocks the car door, pressing the emergency handle cover 1 causes the elastic component 5 of the rotary reset structure to return to its initial state. Regarding this return to the initial state, it is understood that manual pressing is required, and the return is achieved under the force of the elastic component 5.
[0045] In a preferred embodiment of this utility model, when the vehicle receives a collision signal, it automatically powers on the emergency actuator 3, which then starts working and causes the emergency handle cover 1 to automatically pop open. At the instant the emergency handle cover 1 pops open, the door lock pull rope 2 is exposed from the emergency handle cover 1 from its tightened state.
[0046] Understandably, the core of this technical solution lies in the fact that this automotive emergency exterior door handle device, which has both electric and mechanical functions, does not operate during normal vehicle operation. It only enters automatic operation mode in emergency situations (i.e., emergency states). When an emergency occurs, the vehicle powers on the emergency actuator 3, which then activates, automatically opening the emergency handle cover 1. This operation time is controlled within 100ms or a very short period. Furthermore, if the vehicle is powered off, preventing the emergency actuator 3 from functioning properly, mechanical unlocking can be used. The user can directly pull out the emergency handle cover 1, detaching it from the emergency actuator 3. The rotary reset structure, driven by the rotating shaft 4, begins to rotate and generates an upward reaction force through the elastic component 5. The emergency handle cover 1, pushed by this reaction force, springs open, exposing the door lock pull rope 2. Simultaneously, the emergency handle cover 1 separates from the door lock pull rope 2.
[0047] Once the door handle has been opened, it is mechanically reset. The user presses the emergency handle cover 1, which moves downwards until it reconnects with the emergency actuator 3, returning the door to its initial state.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0049] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
[0050] The vehicle emergency exterior door handle device with both electric and mechanical functions, which adopts this utility model, integrates electric and mechanical functions into one door handle. This two-in-one technical solution can effectively overcome practical problems such as vehicle power failure and concealed handle location. It requires fewer parts to realize the door opening action, is simple to operate, and is highly practical. It effectively improves the safety of the vehicle after a collision. Furthermore, since the structure is installed in a non-visible range, it does not affect the overall appearance of the vehicle and conforms to certain aesthetic design requirements.
