The hidden type vehicle exterior door handle further includes a swing block 500, the swing block 500 is rotatably connected with the housing 200, the linked sliding shaft 410 is connected with the swing block 500, and the linked door opening arm 400 moves to cause the swing block 500 to rotate.

The fact that the handle 100 is extendably and retractably mounted to the housing 200 means that the handle 100 can be extended and retracted, specifically, the process in which the handle 100 is extended from the opening 240 of the housing 200 is called extension, the process in which the handle 100 is retracted from the opening 240 into the housing 200 is called retraction, and the handle 100 just covers the opening 240 in the retracted state.

The main rocker arm 300 has an L-shaped structure, and the main rocker arm 300 can rotate around a hinge point with the shell 200, so that the handle 100 is pushed to extend and retract; the handle 100 can pull the linkage door opening arm 400 to enable the linkage door opening arm 400 to move, so that the swing block 500 is driven to rotate through the linkage sliding shaft 410, and the swing block 500 pulls the door opening cable 710 when rotating, so that the door is unlocked.

The primary rocker arm 300 enables the pull handle 100 to extend and retract in a translational manner; when the handle 100 is extended, pulling the handle 100 can rotate the handle 100 around the hinge point of the handle and the main rocker arm 300, and the handle 100 only needs to rotate by a small extent to drive the swing block 500 to rotate by a certain angle through the linkage door opening arm 400.

The outer door handle has a simple and ingenious structure, the handle 100 can be stretched or retracted through translational movement, and unlocking can be performed through the lever principle, so that the outer door handle is labor-saving during unlocking, and the outer door handle is convenient to use.

The first arm 310 and the second arm 320 form an L-shaped structure, and when the first arm 310 rotates, the second arm 320 drives the handle 100 to translate.

As shown in fig. 1-4, the housing 200 includes a front plate 210, a rear plate 220, and two side plates 230, wherein an accommodating space is formed between the front plate 210, the rear plate 220, and the two side plates 230, and the opening 240 is disposed in the front plate 210.

When the handle 100 is in the retracted state, the first arm 310 is inclined to the front plate 210 and forms an acute included angle therebetween; when the handle 100 is extended from the opening 240, the first arm 310 is rotated toward the front plate 210 and an angle between the first arm 310 and the front plate 210 is gradually reduced.

The extension and retraction of the handle 100 can be realized only by rotating the first arm 310 by a small extent, and because the included angle between the first arm 310 and the front plate 210 is an acute angle, the first arm 310 gradually approaches the front plate 210 when extending, the acute angle gradually decreases, and the handle 100 can be extended in a translational manner through the second arm 320, so that the overall structure is very ingenious.

A linear pushing member 600 is disposed in the housing 200 and is retractable along the length direction of the housing 200, and the linear pushing member 600 pushes the first arm 310 to rotate in a direction approaching the front plate 210 when extending.
