Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door handles, and particularly relates to a door handle device. Background Art

[0002] With the accelerating development of new energy vehicles at present, in order to meet the needs of consumers and highlight their differentiated competition, the OEMs put forward higher requirements for the sub - fields of door handle devices, such as the requirements for drag coefficient, appearance structure, finished product function, process structure, product quality and production cost are getting higher and higher. Major vehicle door handle enterprises are researching and developing various hidden and semi - hidden door handles. Compared with the complex mechanical structure and single - function styling of traditional door handle devices, door handle devices with hidden and novel concepts, diverse functions and performances will be quickly popularized and replace the former.

[0003] At the same time, compared with traditional mechanical or fully hidden door handles, the semi - hidden door handle design is widely favored by the market. This is because it incorporates modern and fashionable elements and allows you to directly see the unlocking position, eliminating the possible operation troubles or even ice - breaking troubles of fully hidden door handles; such a design concept not only enhances the sense of closeness between users and vehicles, but also is more easily understood and recognized by consumers. Compared with fully hidden door handles, the semi - hidden design not only has higher aesthetic value, but also has significant performance advantages. It retains the direct operation mode of the original mechanical door handle and also has the high - tech feeling of fully hidden door handles. This innovative concept cleverly combines functional practicality and aesthetic beauty, providing a better experience for users. More importantly, due to the new design, the semi - hidden door handle greatly reduces the risk probability of pinching hands, providing a more comprehensive and reassuring use experience.

[0004] The new energy vehicle market has risen rapidly, and the handle unlocking solutions on the market are uneven. However, considering the safety of vehicle passengers, the solution for the door handle to achieve rapid opening in an emergency is still relatively important. The existing emergency unlocking usually adopts an external - pulling emergency unlocking method, which requires a large force to achieve emergency unlocking, and the emergency unlocking structure is relatively complex.

[0037] Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationship. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but should be regarded as part of the specification when appropriate. In all the examples shown and discussed herein, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0038] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description.

[0050] Emergency unlocking working principle: The emergency unlocking unit of the present utility model conforms to the actual application scenario, such as Figure 7 , by pressing (pushing) the pushing part 4, the pushing part 4 rotates around the pin shaft 3, and the pushing part 4 drags the door lock cable 5 to overcome the corner torque of the torsion spring 6 and the door lock unlocking force. By pulling, a displacement is generated at the head of the movable door lock cable 5, that is, the unlocking stroke of the door lock cable 5 is satisfied, and the unlocking force of the door lock is overcome to achieve the unlocking function of the door lock. After the unlocking function is used up, through the pre-tightening force of the torsion spring 6, the operator stops pressing the pushing part 4, and the automatic reset of the pushing part 4 can be realized.

[0051] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto.
