[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0031] like Figure 1-8 As shown, a mechanical semi-hidden handle 4 straight-pull structure includes a base 1, a rotating arm assembly 2 rotated in the base 1, a handle 4 connected to the rotating arm assembly 2, and a control rod 3 for controlling the unlocking of the vehicle door, and a buckle groove 5 for placing the hand is formed in the handle 4.

[0032] The base 1 has a receiving groove 6 recessed in the vehicle door, the handle 4 is placed in the receiving groove 6 and flush with the vehicle door, and a buckle groove 5 for the hand to be placed is formed on the handle 4, and the handle 4 is manually actuated to move horizontally from the vehicle door.

[0033] Specifically, the rotating arm assembly 2 can slide along the base 1, and the rotating arm assembly 2 includes at least a first position and a second position. When the rotating arm assembly 2 is in the first position, the handle 4 is retracted into the base 1, and the rotating arm assembly 2 is away from the control rod 3, so that the vehicle door is in a locked state; and when the rotating arm assembly 2 is in the second position, the handle 4 extends out of the base 1, and the rotating arm assembly 2 abuts against the control rod 3 to unlock the vehicle door.

[0034] By connecting the handle 4 with the rotating arm assembly 2, the handle 4 can be pulled to extend horizontally. During the extension of the handle 4, the rotating arm assembly 2 will rotate and slide horizontally along the base 1, and when the handle 4 is extended, the rotating arm assembly 2 will abut against the control rod 3, causing the control rod 3 to rotate, and pulling the unlocking rope to unlock the door, thereby unlocking the door. Compared with the hidden handle 4 with transmission, the structure is simpler, no electric structure is involved, and assembly is more convenient.

[0035] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, further explanation of the implementation method of the rotating arm assembly 2 in this embodiment is provided, the rotating arm assembly 2 includes a first rotating arm 101 and a second rotating arm 102 rotated on the base 1, the first rotating arm 101 and the second rotating arm 102 have a first rotating end connected to the handle 4, and a second rotating end connected to the base 1, a rotating shaft 103 is arranged on the second rotating end, and a sliding groove 104 is formed on the base 1 for the rotating shaft 103 to slide, and the sliding groove 104 is arranged in a straight line along the length direction of the base 1. When the user pulls the handle 4, the first rotating arm 101 and the second rotating arm 102 will rotate, and the rotating shaft 103 will slide along the sliding groove 104, and when the handle 4 is pulled out, the rotating shaft 103 will abut against the control rod 3, so that the control rod 3 rotates, thereby unlocking the car door.

[0036] The upper and middle parts of the base 1 are both provided with sliding grooves 104 , and the first rotating arm 101 and the second rotating arm 102 are respectively slidably arranged in the sliding grooves 104 , thereby greatly improving the sliding stability of the rotating shaft 103 .

[0037] Furthermore, a transmission rod 105 is connected between the rotating shaft 103, and the transmission rod 105 drives the first rotating arm 101 and the second rotating arm 102 to move synchronously, and the transmission rod 105 moves linearly with the transmission shaft 103, further improving the stability of the handle 4 when extending and retracting.

[0038] In addition, a reset rod 106 is arranged between the second rotating arm 102 and the rotating shaft 103, and a first torsion spring 107 is arranged on the reset rod 106. One end of the first torsion spring 107 abuts against the reset rod 106, and the other end abuts against the second rotating arm 102. The first torsion spring 107 will drive the reset rod 106 to reset, so that the first rotating arm 101 and the second rotating arm 102 will be automatically reset, thereby realizing the automatic retraction of the handle 4.

[0039] like Figure 3 , Figure 4 , Figure 5As shown, as a further explanation of the connection of the handle 4 in this embodiment, the ends of the first rotating arm 101 and the second rotating arm 102 are hinged with a mounting block 108, and the mounting block 108 is connected to the handle 4.

[0040] Among them, an abutting protrusion 201 is formed at the end of the mounting block 108, and the handle 4 is locked on the mounting block 108 by means of screws. As the screws tighten the handle 4, the abutting protrusion 201 will press against the handle 4, making the connection between the handle 4 and the mounting block 108 more stable.

[0041] Furthermore, a sliding channel 109 is formed on the base 1 for the mounting block 108 to slide. The mounting block 108 slides in the sliding channel 109, and the sliding channel 109 is arranged perpendicular to the vehicle door, so that the handle 4 can be horizontally extended or retracted on the vehicle door with higher stability.

[0043] The control rod 3 is provided with a second torsion spring 204 , one end of which abuts against the control rod 3 , and the other end abuts against the base 1 , so that the control rod 3 has an automatic reset function. When the rotating shaft 103 is away from the control rod 3 , the control rod 3 is reset.

[0044] like Figure 6 , Figure 7 As shown, in some other embodiments, an inertia lock 301 is rotatably provided on the base 1, a third torsion spring 302 is sleeved on the inertia lock 301, a limiting protrusion 303 is provided on the base 1, one end of the third torsion spring 302 abuts against the limiting protrusion 303, and the other end abuts against the inertia lock 301, so that the inertia lock 301 always has a movement tendency toward the limiting protrusion 303.

[0045] In addition, a blocking protrusion 304 is formed on the inertia lock 301, which abuts against the limiting protrusion 303 and has a motion trajectory that limits the rotation of the control rod 3. When the vehicle door is hit, the blocking protrusion 304 will rotate and block the control rod 3 from rotating, thereby preventing the vehicle door from being unlocked during the collision, thereby improving the safety of the vehicle door.
