[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0032] Please refer to Figures 1-2 , Figures 13-15 To solve the above technical problems, the present application comprises a handle cover 1, a handle body 2, a driving rod 3, a supporting plate 4, a connecting rod 5, a swing arm 6, a transmission rod 7, a rotating rod 8, and a pull bar 9. The handle cover 1 is arranged on the handle body 2. When installed, the handle cover 1 is flush with the outer panel of the door and is flush with the outer panel of the door. Unlike the traditional door handle, the handle assembly is fixed on the inner panel of the door by three fixing bolts, and the handle assembly and the outer panel are sealed by a sealing strip.

[0033] Further, the supporting plate 4 is fixed to the door panel of the automobile, and the handle body 2, the driving rod 3, the swing arm 6, and the transmission rod 7 are all installed on the supporting plate 4. In the use process, the handle, the transmission rod 7 and other components are attached to the supporting plate 4 and are pushed out together with the supporting plate 4.

[0034] The present application further comprises an actuator, the actuator comprises an output shaft, the actuator is driven to rotate the output shaft after receiving an electrical signal, and a cam is installed on the output shaft.

[0035] Further, the driving rod is hinged to the supporting plate, and a driving arm is further fixedly installed on the driving rod. The driving arm abuts against the cam. In operation, the actuator drives the cam to rotate, the cam abuts against the driving arm, and the driving rod is further driven to move.

[0036] Please refer to Figures 3-5 , the driving rod 3 is fixed at one end of the supporting plate 4, the swing arm 6 is installed at the end of the supporting plate 4 away from the driving rod 3, one end of the connecting rod 5 is connected to the driving rod 3 and the other end is connected to the swing arm 6, the swing arm 6 moves around the swing arm rotating shaft, and the swing arm rotating shaft is fixed on the handle body 2. Since the swing arm 6 is connected to the driving rod 3 through the connecting rod 5, the movement form of the swing arm 6 is synchronized with that of the driving rod 3.

[0037] The driving rod 3 is hinged on the handle body 2, and the movement of the driving rod 3 drives the handle body 2 to pop out, i.e. from the original state to the state of pushing the handle out of the door panel.

[0038] Please refer to Figure 7 , the transmission rod 7 is fixed at one end of the supporting plate 4 away from the driving rod 3, the transmission rod 7 is hinged on the handle body 2, and the transmission rod 7 is also connected to the rotating rod 8, the transmission rod 7 transmits the movement of the hand-pulled handle to the rotating rod 8, and drives the pull bar 9 to realize unlocking and opening the door.

[0039] Please refer to Figure 6 , the rotating rod 8 is installed at one end of the supporting plate 4 away from the driving rod 3, and is hinged with the transmission rod 7, the pull bar 9 is fixed on the rotating rod 8, when the handle is pulled, the handle body 2 is pulled to drive the transmission rod 7 to rotate, the transmission rod 7 drives the rotating rod 8 to rotate, and further drives the pull bar 9 to move a certain stroke to be unlocked.

[0040] From the outside of the car, the handle half assembly has three states, the initial position of the handle is the state of the handle when the car is normally running and locked, the pre-opening position of the handle is the state of the handle when the door is prepared to be opened, and the maximum opening position of the handle is the state of the handle when the door is unlocked and opened.

[0041] The three states are explained as follows:

[0042] Please refer to Figure 8 , the initial state of the handle: the handle assembly is retracted into the panel, at this time, it is the hidden state of the door handle, the position of the internal rod structure of the handle is shown in the following figure, at this time, the four-bar mechanism composed of the driving rod 3, the connecting rod 5, the supporting plate 4 and the swing arm 6 is in the retracted state.

[0043] Please refer to Figures 9-10 , the handle extension state: the output torque of the actuator is transmitted to the driving rod 3 through the cam, and drives the four-bar mechanism composed of the driving rod 3, the connecting rod 5, the supporting plate 4 and the swing arm 6 to be pushed out to the maximum position, at this time, the handle is extended out of the panel.

[0044] And the transmission rod 7 in the handle is also pushed out together with the supporting plate 4 and is in edge contact with the rotating rod 8.

[0045] Please refer to Figures 11-12 , the handle opening state: pulling the handle at the same time drives the transmission rod 7, at this time, it drives the rotating rod 8 to rotate, the pull bar 9 is hinged on the rotating rod 8 and rotates with the rotating rod 8 at the same time to produce a displacement, thereby driving the pull bar 9, unlocking the lock block, and opening the door.

[0046] The maximum position of the connecting rod and the rotating rod 8 is shown in Figure 12 .

[0047] It will be obvious to a person skilled in the art that the application is not limited to the details of the foregoing exemplary embodiments and can be implemented in other concrete forms without departing from the spirit or essential characteristics of the application. The embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No reference signs in the claims should be considered as limiting the scope of the claims to the identity of the reference signs therein.

[0048] Furthermore, it should be understood that although the description is made on the basis of the embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.
