Thereby, the initial position of the external handle structure 1 can be locked, thereby achieving the safety protection and safeguarding effect for the hidden handle structure driven by mechanical driving force, and avoiding the situation where the handle is accidentally opened to the welcome position.

[0028] Specifically, the outer handle structure 1 is flip-connected to the handle base 11 via a rotating axis, the swing plane of the positioning plate 4051 is parallel to the moving plane of the outer handle structure 1 , and the anti-mistouch component 5 is arranged in a direction perpendicular to the swing plane of the positioning plate 4051 .

The positioning head 51 is made of ferromagnetic material, such as a permanent magnet or a magnetic tin-copper sheet. The positioning head 51 is extended or retracted by magnetic attraction or repulsion. In specific implementation, a retraction spring or compression spring can also be arranged between the electromagnetic component and the positioning head 51 to provide a balancing force in the opposite direction of the magnetic driving force, so that the positioning head 51 can be repeatedly extended and retracted.

[0029] like Figure 3 As shown, it is a schematic diagram of the structure of the push-pull locking structure for preventing accidental touch of the welcome guest under the first embodiment, wherein the driving component 52 is connected with the automobile door lock mechanism 6 by electrical signals, and the automobile door lock mechanism includes door lock mechanisms such as door lock, electric suction lock, opening and closing system, and the anti-accidental touch component 5 is fixedly installed inside the handle base 11, and the driving component 52 is used to drive the positioning head 51 to perform telescopic movement along the direction perpendicular to the swing plane of the positioning plate 4051, and when the anti-accidental touch component 5 is in the locked state, the top of the positioning head 51 abuts against one side of the positioning plate 4051 close to the zero balance position of the positioning component 405, and when the anti-accidental touch component 5 is in the free state, the positioning head 51 and the positioning plate 4051 are in a separated state.

Therefore, the anti-accidental touch component 5 can also be applied to a flat push handle. The opening structure 2 of the flat push handle is the same as the flip handle. The opening structure acts on the handle swing arm 112 of the flat push handle, so that the handle swing arm 112 slides and reciprocates in the handle base 11. When the anti-accidental touch component 5 acts on the Push-Pull opening structure 2, it can be applied to any other handle structure having a similar Push-Pull opening structure 2. The focus of this application is on the idea of ​​preventing accidental touch and the disclosure of the optimal locking method. The flip handle can include multiple opening methods, driven by a variety of opening structures with different structures. For example, the adjustment plate of the locking component 405 on the automatic return flip handle with patent number CN202110137818.8 can also realize the function of welcoming guests and preventing accidental touch. Specifically, in this embodiment, the Push-Pull opening structure 2 includes a driving component and a locking component 405, the locking component 405 is used to limit the position of the driving component so that the outer handle structure 1 is subjected to two forces in opposite directions when it is in an initial horizontal posture, the locking component 405 includes a balance spring 4050 and a positioning plate 4051, the locking component 405 includes a zero balance position, the balance spring 4050 is used to provide a driving force to the positioning plate 4051 to make the locking component 405 tend to the zero balance position, when the outer handle structure 1 is in an initial horizontal posture, the locking component 405 is not in the zero balance position; the anti-mistaken touch component 5 acts on the positioning plate 4051 to lock the position of the positioning plate 4051.

[0031] In the embodiment of the flip handle, the outer handle structure 1 includes a handle swing arm 112, the handle swing arm 112 includes a flip part 1121 and an operating part 1120, the drive assembly includes a main drive assembly 3 and a secondary drive assembly 4, the main drive assembly 3 and the secondary drive assembly 4 are transmission connected; the flip part 1121 is provided with a first transmission structure, the main drive assembly 3 is provided with a second transmission structure matching the first transmission structure, and the secondary drive assembly 4 is provided with a third transmission structure matching the first transmission structure; the main drive assembly 3 includes a main gear 303 and a main spring 304, the main spring 304 is used to drive the main gear 303 to provide the outer handle structure 1 with a driving force for transitioning from a pressed-down triggered position posture to a welcoming position posture; the secondary drive assembly 4 includes a positioning assembly 405 and an engaging cam 406, the positioning assembly 405 is used to limit the position of the engaging cam 406 so that the The handle structure is in an initial horizontal posture, the engaging cam 406 is in transmission connection with the main gear 303, the positioning assembly 405 includes a balance spring 4050 and a positioning plate 4051, the positioning assembly 405 includes a zero balance position, and the balance spring 4050 is used to provide a driving force to the positioning plate 4051 to make the positioning assembly 405 tend to the zero balance position; when the handle structure is in the initial horizontal posture, the positioning assembly 405 is not in the zero balance position; a positioning column 4060 is provided on the protruding portion of the engaging cam 406, and a limiting groove 4052 matching the positioning column 4060 is provided on the positioning plate 4051, when the handle structure is in the initial horizontal posture, the positioning column 4060 and the limiting groove 4052 are in a matching position, and when the positioning assembly 405 is in the zero balance position, the positioning column 4060 and the limiting groove 4052 are in a separation position. When the handle structure 1 is in the door opening position, the positioning column 4060 and the limiting groove 4052 are in a matching position.

[0032] like Figure 4 and Figure 5As shown, it is a structural schematic diagram of the second embodiment of the Push-Pull locking structure for preventing accidental touch of the welcoming guest. The difference from the first embodiment is that the anti-accidental touch component 5 is mechanically linked with the automobile door lock mechanism 6, the driving component 52 is connected with the automobile door lock mechanism 6, and the traction part of the automobile door lock mechanism 6 provides a traction force. The driving component 52 includes a locking arm 521 rotatably connected to the handle base 11 and a hinged portion 522 arranged at one end of the locking arm 521, the positioning head 51 is arranged at the other end of the locking arm 521, and the traction part is fixedly connected to the end of the locking arm 521.

[0033] The third embodiment of the Push-Pull locking structure is different from the first embodiment in that a positioning hole matching the positioning head 51 is provided on the positioning plate 4051, and when the anti-accidental touch component 5 is in a locked state, the top of the positioning head 51 is in conflict with the positioning hole, and when the anti-accidental touch component 5 is in a free state, the positioning head 51 and the positioning hole are in a separated state.

[0034] Working principle: When the hidden handle structure driven by mechanical driving force is pressed down to trigger, the action process is that the handle is automatically bounced to the welcoming position by pressing down. When the handle with the anti-mistaken touch structure is opened, the door lock unlocking signal needs to be pressed by the car key first. When the door lock signal is not pressed, the anti-mistaken touch component 5 is in a locked state. When opening the door, the door lock signal is first pressed to separate the positioning head 51 and the positioning plate 4051. At this time, the handle is pressed down to trigger so that the handle swing arm can bounce to the welcoming position under the action of the driving component. By setting the anti-mistaken touch component 5 electrically and / or mechanically linked with the car door lock mechanism 6, the anti-mistaken touch opening of the handle can be avoided, and the reliable opening of the handle is achieved.

[0035] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
