As shown in figures 1-4, the vehicle door handle transmission mechanism comprises a base 1, wherein a handle 2 and a swing arm 3 are connected to the base 1 in a rotating mode, the position of the handle 2 at least comprises a hidden position, a middle unfolding position and a maximum unfolding position, at least one tooth is arranged on the swing arm 3, a transmission guide surface which is matched with the tooth in a corresponding mode is arranged on the handle 2, and the transmission guide surface is a cam surface. The included angle between the direction of the interaction force of the contact position of the teeth and the transmission guide surface and the connecting line of the contact position and the rotation center of the swing arm 3 is 70-110 degrees.

The swing arm 3 is provided with a first ball head tooth 31 and a second ball head tooth 32, the transmission guide surface comprises a first transmission guide surface 21 and a second transmission guide surface 21 which are respectively matched with the first ball head tooth 31 and the second ball head tooth 32, and the first transmission guide surface 21 and the second transmission guide surface 21 can be cam surfaces. During the process of unfolding the handle from the hidden position to the maximum unfolding position, the matching of the first ball head teeth 31 and the first transmission guide surface 21 and the matching of the second ball head teeth 32 and the second transmission guide surface 21 are carried out in sequence.

As shown in fig. 2, the handle 2 is in the hidden position, in which the first button 31 engages the first transmission guide surface 21; as shown in fig. 3, the handle 2 is in the intermediate deployed position, in which the first button 31 is about to disengage from the first transmission guide surface 21 and the second button 32 is about to contact the second transmission guide surface 22; as shown in fig. 4, the handle 2 is in the maximum extended position, in which the second button 32 engages the second transmission guide surface 22 and the first button 31 is disengaged from the first transmission guide surface 21. Therefore, in the unfolding process of the handle 2, the first ball head teeth 31 are firstly contacted and matched with the first transmission guide surface 21, and then the second ball head teeth 32 are matched with the second transmission guide surface 21, so that in the whole rotation stroke, the two groups of round head teeth and the transmission guide surface are adopted for realizing relay, stable transmission is ensured, and meanwhile, the space can be saved to a great extent

Referring to fig. 5, the handle 2 of the present invention is provided with a handle leg 23, the base 1 is further provided with a slider 4 for pushing the handle leg 23 to move so as to rotate the handle 2 from the hidden position to the intermediate deployed position, the slider 4 is connected with an actuator 5 for driving the slider to move, the slider 4 is further provided with a support groove 42 for supporting the handle leg 23 pushed to the intermediate deployed position so as to reduce damage to the actuator 5 caused by an external force applied to the handle 2, and the handle leg 23 reaches the intermediate deployed position, namely, contacts with the support groove 42 or the handle leg 23 reaches the intermediate deployed position and is further away from the support groove 42.

s1: the actuator 5 pushes out the slide block 4, and the slide block 4 pushes the handle support leg 23 to move so as to drive the handle 2 to rotate;

s2: the handle 2 is rotated from the stowed position to the intermediate deployed position and the support slots 42 then engage the support handle legs 23.

In step S2:

s21: when the handle support legs 23 reach the intermediate unfolded position, namely contact with the support grooves 42, the actuating mechanism 5 stops acting;

s22: when the handle legs 23 reach the intermediate extended position a distance further from the support grooves 42, the actuator 5 drives the slider 4 to move a further distance, while the handle legs 23 are not moved until the support grooves 42 fully support the handle legs 23.

The working principle of the integral vehicle door handle is as follows:
