When the user desires to open the door, the user pulls the handle 20, and the handle 20 is transitioned from the deployed state to the unlocked state. The handle 20 pulls the connecting rod 60 to rotate, the connecting rod 60 drives the first gear transmission mechanism 31 to rotate, and the first gear transmission mechanism 31 drives the second gear transmission mechanism 32 to rotate, so that the unlocking component of the door handle is pushed to rotate, and the door is opened.

The embodiment of the utility model also discloses a vehicle door, which comprises a vehicle door body and the door handle in the embodiment, wherein the door handle is connected with the vehicle door body.

It should be noted that, in the embodiment of the present utility model, the door handle included in the vehicle door has the same structure as the door handle described in the above embodiment, and the beneficial effects thereof are also similar, and are not repeated here.

The embodiment of the utility model also discloses a vehicle, which comprises a vehicle body and the vehicle door in the embodiment, wherein the vehicle door is connected with the vehicle.

It should be noted that, in the embodiment of the present utility model, the vehicle includes a door having the same structure as the door described in the above embodiment, and the beneficial effects thereof are similar, and are not described herein again.

It should be noted that, in the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described as different from other embodiments, and identical and similar parts between the embodiments are all enough to be referred to each other.

While alternative embodiments of the present utility model have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. It is therefore intended that the following appended claims be interpreted as including alternative embodiments and all such alterations and modifications as fall within the scope of the embodiments of the utility model.

Finally, it is further noted that relational terms such as first and second, and the like are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that an article or terminal that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such article or terminal. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude that an additional identical element is present in an article or terminal device comprising the element.

While the foregoing has been described in some detail by way of illustration of the principles and embodiments of the utility model, and while in accordance with the principles and implementations of the utility model, those skilled in the art will readily recognize that the utility model is not limited thereto.
