[0034] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0035] like Figures 1 to 12 As shown, the concealed door handle includes a base 1, a handle body 6, a rotating arm 4, and an actuator 2 for pushing the rotating arm to swing. The base 1 is a plate-shaped structure with an arc-shaped transition at the edge. The handle body 6 is hinged to the outside of the base 1 via a handle pin 9. One end of the rotating arm 4 is hinged to the back of the base via a rotating arm pin 7. The rotating arm and the handle body are movably connected via a ball joint structure. The movable ball joint structure enables the conversion of rotation in different directions. The actuator 2 is fixed on the base, and the push rod of the actuator 2 is set opposite to the other end of the rotating arm 4.

[0036] When the concealed handle freezes, the actuator push rod pushes the rotating arm, which in turn rotates the ball joint structure to push the handle frame, allowing the concealed door handle to pop out normally in winter. This improves the ice-breaking ability and strength of the concealed door handle, thereby enhancing its reliability. Furthermore, the structure is compact, occupies little space, and is easy to arrange and install.

[0037] The base 1 is an integral injection molded structure, and other components are integrated on the base 1 to form an assembly. The base has three screw holes on its side, and reinforcing ribs are provided on the base corresponding to the screw holes. The base is fixed to the car door by three screws. The base has a flanged reinforcing rib structure on its side. The structure is stable and reliable, and the cost is relatively low.

[0038] The back of the base 1 is provided with an actuator groove and a guide groove. The actuator groove is a contour groove, and the shape of the actuator 2 is adapted to the contour groove. The actuator groove is located on one side of the base, and the edge of the base is provided with an opening for the connector to extend out, which is convenient for wire harness insertion. The actuator is set in the actuator groove, and the side of the actuator housing is provided with a set of small fixing holes, which are fixed by small screws. The structure is compact and the fixation is reliable. The actuator push rod is movably located in the guide groove. The actuator push rod is guided and limited by the straight guide groove. The guide groove restricts the actuator push rod to move only in a straight line. The end of the push rod can be provided with a rubber coating structure to avoid abnormal noise during operation.

[0039] Actuator 2 is an electric actuator. The actuator screw 201 of the actuator is connected to the external actuator push rod 3. The end of the screw and one end of the actuator push rod are connected by a snap-fit, which makes assembly simple. The other end of the actuator push rod is the push end, which is an arc-shaped push head with low running resistance.

[0040] Furthermore, the upper end of the rotating arm 4 is hinged to the back of the base via the rotating arm shaft pin 7 and the rotating arm torsion spring 8. The rotating arm torsion spring 8 is used for the reset of the rotating arm. The lower end of the rotating arm 4 corresponds to the actuator push rod 3. The side of the lower end of the rotating arm 4 corresponding to the push rod end is beveled, resulting in low pushing resistance. The middle part of the rotating arm 4 is movably connected to the ball head structure. The structure is compact.

[0041] The inner side of the handle body 6 is provided with a handle frame 601. The handle frame is hinged to the outer side of the base through the handle pin 9 and the handle torsion spring 10. A ball head is provided on the inner side of the handle pin on the handle frame 601. A through hole is provided on the base corresponding to the ball head. The space of the through hole is relatively large and will not interfere with the ball head. The ball head passes through the through hole and is movably connected to the rotating arm. The ball head on the handle frame is aligned with the handle pin.

[0042] This invention employs a fully voltage-driven actuator motor to propel a rotating arm, which in turn pushes the handle frame via a ball joint structure. The door handle continues to pop out until it reaches the designated position. This handle structure boasts high strength, minimal force loss in the transmission mechanism, and an ice-breaking force exceeding 120N, capable of breaking through ice layers up to 2mm thick. It eliminates the problem of concealed door handles being unable to open in winter, improving their ice-breaking ability and reliability.

[0043] Furthermore, a control lever 5 is provided on the back of the base 1 corresponding to the other end of the rotating arm. The control lever is hinged to the base, and one end of the control lever is connected to the door lock of the car door through a pull cable; that is, the rotating arm is located between the control lever and the electric actuator, and the structure is compact.

[0044] Both the rotating arm 4 and the control rod 5 have matching arc-shaped structures on opposite sides. One side of the control rod has an arc-shaped protrusion, and the other side of the rotating arm has an arc-shaped groove that matches the protrusion. The lower end of the rotating arm provides stable and reliable swinging of the control rod with low resistance. Preferably, the lower end of the control rod is hinged to the back of the base via a control rod pin 11 and a control rod torsion spring 12. The upper end of the control rod 5 has a connection hole for connecting to a pull cable. The hinge of the rotating arm is located at the upper end of the rotating arm, and the hinge of the control rod is located at the lower end of the control rod. The hinge positions of the rotating arm and the control rod are staggered vertically, resulting in a stable and reliable structure.

[0045] The back of the base has a protruding cylindrical structure with a central shaft hole that connects the inside and outside. The rotating arm has a sleeve structure that fits onto the cylindrical structure. The rotating arm pin passes through the shaft hole and the sleeve structure. The rotating arm torsion spring is fitted onto the sleeve structure, creating a stable and compact fit. The control lever's hinge structure uses a similar rotating arm structure, resulting in a compact design.

[0046] The outer side of the base has a groove corresponding to the handle frame. The top and bottom of the groove on the base have corresponding pin holes. The handle frame has a shaft hole corresponding to the pin hole. The vertically set handle pin passes through the top pin hole and the handle frame and the bottom pin hole to achieve a hinge connection. The upper part of the handle frame has a connecting sleeve. The handle pin passes through the connecting sleeve. The handle torsion spring is sleeved on the connecting sleeve. The integrated design is stable, reliable and compact.

[0047] The upper end of the rotating arm 4 is provided with an extension limit part, which is integrally injection molded; the base is provided with a limit protrusion corresponding to the extension limit part to limit the swing stroke of the rotating arm, so that the operation is stable and reliable; the control rod for controlling the door lock opening is integrated on the base and works with the rotating arm for control. The structure is simple, integrated, easy to install, and effectively reduces costs.

[0048] This invention patent provides a concealed door handle structure with ice-breaking function, aiming to eliminate the problem of concealed door handles being unable to be opened in winter, improve the ice-breaking ability and reliability of concealed door handles; and it occupies little space and is easy to install.

[0049] The working process of this invention is as follows:

[0050] When the electric actuator operates, the actuator push rod pushes the lower end of the rotating arm, causing the rotating arm to swing around its pivot pin. The rotating arm, through a ball joint structure, drives the handle body to rotate around its pivot pin, causing the concealed handle to pop out after ice breaking. Once the handle is in normal working order, the electric actuator stops working. A person can then grasp one end of the handle and pull it outwards. The handle body continues to rotate around its pivot pin, driving the rotating arm to continue swinging. The rotating arm drives the control lever to rotate, and the control lever pulls the door lock via a cable to unlock it. This invention allows concealed door handles to pop out normally in winter, ensuring normal handle function. It features an integrated design, compact structure, small footprint, and is easy to arrange and install.

[0051] The concealed door handle of this invention comprises an actuator assembly, an actuator push rod, a base, a handle frame, a rotating arm, and a control lever, assembled into a handle assembly. Its structure is as follows: Figure 1 As shown. The actuator contains an internal motor that electrically drives the actuator screw along the X-axis via a worm gear structure. This drives the actuator push rod to push the rotating arm, causing the rotating arm and handle frame to rotate around their corresponding pivot pins, thus popping the handle out. Pushing the handle frame, the door handle continues to pop out until it reaches the designated position. This invention allows concealed door handles to pop out normally in winter, ensuring normal handle function; it also improves the ice-breaking ability and strength of concealed door handles, and enhances their reliability.
