Description

Technical Field

[0001] This invention relates to the field of door handle equipment, and in particular to a concealed mechanical swing handle. Background Technology

[0002] Currently, most car door handles are exposed and protruding. This design faces several limitations. Firstly, the handle's shape must match the car's side profile for a pleasing appearance. Secondly, because the handle is fully exposed, both the inner and outer surfaces are easily soiled, making it easy for drivers to get their hands dirty when opening the door. Furthermore, the protruding handle not only detracts from the car's overall appearance but also increases wind resistance, raising drag and wind noise. To address these issues, many manufacturers have improved the handle structure, creating retractable, concealed handles.

[0003] Because the position of a concealed door handle needs to be changed, and it involves both electric and mechanical mechanisms, it has more parts and a much more complex structure compared to traditional fixed door handles. In actual use, existing concealed door handles still have several drawbacks, such as: 1. The electric mechanism is complex, with numerous parts, resulting in high cost and a higher failure rate during actual use, leading to a decrease in the overall reliability of the handle; 2. Current mechanical handles require one hand to hold the handle while the other hand opens the door, requiring both hands to operate simultaneously, causing inconvenience; 3. The electric mechanism requires pre-activation of the vehicle's electrical circuits and produces motor noise during operation. Summary of the Invention

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0041] Reference Figures 1 to 17 A concealed mechanical swing handle, comprising:

[0042] The handle body 1 is flush with the outer surface of the door;

[0043] The handle base 2 is installed inside the car door, and the handle body 1 is installed in the handle base 2;

[0044] Unlocking device 3, which is movably installed inside the car door, is tractively connected to the handle body 1 and to the car door lock. The handle body 1 drives the unlocking device 3 to operate and realize the unlocking function of the car door lock; it also includes:

[0045] Push switch 6 has at least an initial state, an initiation compression state, and a release extension state;

[0046] The transmission part 4 and the unlocking part 5 are connected. The push switch 6 is connected to the handle body 1 via the transmission part 4, and the handle body 1 is connected to the unlocking device 3 via the unlocking part 5. Preferably, the transmission part 4 and the unlocking part 5 are integrally formed with the handle body 1, which improves reliability, facilitates processing, and eliminates the need for manual assembly.

[0047] The handle body 1 has at least a hidden position retracted into the door, a press-activated position, a pre-expanded position extended outside the door, and an unlocked position when the door is opened; wherein, the hidden position of the handle body 1 corresponds to the initial state of the Push switch 6, the press-activated position of the handle body 1 corresponds to the start-up compression state of the Push switch 6, and the pre-expanded position of the handle body 1 is adapted to the release extension state of the Push switch 6.

[0048] To achieve the various functions of the Push switch 6, this embodiment provides a preferred structure for the Push switch 6: it includes a switch housing 7, a first slider 8 and a second slider 9 located within the switch housing 7 and movably connected to the handle base 2, and a Push switch body 10 disposed within the second slider 9. The first slider 8 and the second slider 9 are movably disposed within the switch housing 7, and the Push switch body 10 is drive-connected to the first slider 8. Preferably, the Push switch body 10 and the second slider 9 are separately formed and then assembled together later; however, custom-made production molds can also be used to achieve processing, allowing the Push switch body 10 and the second slider 9 to be integrally formed.

[0049] To enable the first slider 8 and the second slider 9 to move relative to the handle base 2, the handle base 2 is provided with a guide groove 11. The first slider 8 is provided with a first guide rib 12, and the second slider 9 is provided with a second guide rib 13. Both the first guide rib 12 and the second guide rib 13 are slidably disposed in the guide groove 11. Through the cooperation of the first guide rib 12 and the guide groove 11, the first slider 8 can move regularly along the trajectory of the guide groove 11. At the same time, through the cooperation of the second guide rib 13 and the guide groove 11, the second slider 9 can move regularly along the trajectory of the guide groove 11.

[0050] To prevent the first slider 8 and the second slider 9 from detaching from the handle base 2 during movement, which could lead to malfunction of the components and prevent normal operation, two limiting protrusions 14 are provided on the handle base 2. These two limiting protrusions 14 are respectively located on both sides of the guide groove 11, and the gap between the two limiting protrusions 14 forms a movable space 15 for the switch housing 7 to move back and forth. Each limiting protrusion 14 has an anti-detachment groove 16 on the side near the guide groove 11. Limiting ribs 17 protrude from both sides of the switch housing 7. The limiting ribs 17 are inserted into the anti-detachment grooves 16 and can move along the anti-detachment grooves 16. Through the cooperation of the limiting ribs 17 and the anti-detachment grooves 16, the switch housing 7 can be effectively limited, thereby limiting the first slider 8, the second slider 9, and the Push switch body 10 inside the switch housing 7, ensuring the normal operation of the Push switch 6.

[0051] In this invention, the Push switch 6 is connected to the transmission part 4 via a lever arm 18. Preferably, the lever arm 18 is Y-shaped, and its two ends are hinged to the Push switch 6 and the transmission part 4 respectively via first pivot pins 21. The Y-shaped lever arm 18 enables transmission between the Push switch 6 and the handle body 1, and allows the handle body 1 to have a swing-out opening action.

[0052] In this embodiment, a damper 19 is provided in the handle base 2, and the damper 19 is pulsatorically connected to the handle body 1. The damper 19 provides a better feel for the user when operating the handle body 1, and also effectively cushions and protects the various components. Preferably, the damper 19 is a gear-type damper, and the handle body 1 is provided with a gear portion 20 that meshes with the gear-type damper.

[0053] In this invention, the handle body 1 is rotatably connected to the handle base 2 via a second pivot pin 22, and a first return torsion spring 23 is sleeved on the second pivot pin 22. One end of the return torsion spring abuts against the handle base 2, and the other end abuts against the handle body 1. The unlocking device 3 is rotatably connected to the handle base 2, and a second return torsion spring 24 is provided between the unlocking device 3 and the handle base 2. With the first return torsion spring 23 and the second return torsion spring 24, after the handle body 1 is used, the handle body 1 and the unlocking device 3 can be automatically restored to their initial position (hidden position).

[0054] The Push switch 6 in this invention has at least three position states: initial state, start-up compression state, and release extension state. The switching between the three states can be achieved by pressing (i.e., the relative position change of the first slider 8 and the second slider 9).

[0055] In this invention, the handle body 1 has at least four different positions: a hidden position retracted into the car door, a press-activated position, a pre-expanded position extended outside the car door, and an unlocked position when the car door is opened. The handle body 1 switches between these four different positions during use, and its specific working principle is as follows:

[0056] When the handle body 1 is switched from the hidden position to the press-activated position, the tail end of the handle body 1 is pressed first, causing the tail end to move inward toward the car door, while the other end (front end) is lifted and moves outward toward the car door. At this time, the transmission part 4 on the handle body 1 drives the switch housing 7 to move forward through the lever arm 18, and drives the first slider 8 to move toward the second slider 9 so that the two are closer together. Then the first slider 8 abuts against the Push switch body 10 inside the second slider 9 and triggers the activation of the Push switch 6 (that is, the Push switch 6 switches from the initial state to the start compression state).

[0057] When the handle body 1 switches from the press-activated position to the pre-expanded position, the Push switch 6 is in the start-up compression state. At this time, after the user presses the end of the handle body 1, he releases the handle body 1, and the external pressure disappears. Thus, the Push switch 6 can automatically change from the start-up compression state to the release extension state. During this process, the push rod 25 on the Push switch body 10 pushes the first slider 8 and makes the first slider 8 move away from the second slider 9. At the same time, it drives the switch housing 7 to slide backward relative to the handle base 2, and then drives the handle body 1 to rotate through the lever arm 18 to realize the lifting (end pops out of the car door) swing function.

[0058] When the handle body 1 is switched from the pre-expanded position to the unlocked position, the handle body 1 is already in the pre-expanded position. The tail end of the handle body 1 protrudes and forms a certain angle with the car door to facilitate hand insertion. Then, the user holds the handle body 1 and pulls it outward gently, so that the unlocking part 5 on the handle body 1 contacts the unlocking device 3 and drives the unlocking device 3 to operate, thereby realizing the unlocking function of the car door lock. At the same time, the transmission part 4 on the handle body 1 drives the switch housing 7 to move further backward through the lever arm 18. At this time, the first guide rib 12 on the first slider 8 moves to the end of the guide groove 11 and is limited and no longer moves backward. The second slider 9 moves the Push switch body 10 closer to the first slider 8, so that the first slider 8 abuts against the Push switch body 10 and triggers the Push switch 6, so that the Push switch 6 has a tendency to return from the released extended state to the initial state.

[0059] When the handle body 1 is switched from the unlocked position to the hidden position, after the user opens the car door and releases the handle body 1, the handle body 1 returns to the initial hidden position under the action of the first reset torsion spring 23, and the unlocking device 3 also returns to the initial position under the action of the second reset torsion spring 24. At the same time, since the handle body 1 and the Push switch 6 are no longer affected by external force after the handle body 1 is released, the Push switch 6 also returns to the initial state from the released extended state, and then the handle body 1 is hidden in the handle base 2, which is flush with the outer surface of the car door.

[0060] It should be noted that the handle structure of the present invention is not limited to the exterior door handle, but can also be applied to the interior of a vehicle or other scenarios.

[0061] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the invention shall still fall within the protection scope of the present invention.
