Technical Field
[0001] The present application relates to the technical field of automobile parts, and in particular to a hidden door handle. Background Art
[0002] A door handle is a mechanical structure attached to a vehicle door and used to open it. Door handles are generally classified into pull-out, flip-up, and concealed styles, depending on their structure. Concealed door handles are widely used in new energy vehicles because they can effectively reduce drag and increase range during driving.
[0003] Conventional hidden door handles are usually driven on one side by a driver, that is, the driver is set on one side of the door handle and connected to the door handle through a single connector. When the driver is running, the connector drives the door handle to extend. Although this structure can complete the extension of the door handle, the connection method of the single connector is not firm, and the overall structural strength of the door handle is low. In particular, after the door handle is used for a long time and is subjected to stress, the connector is prone to failure or even breakage. Utility Model Content

[0029] Reference Figure 1 as well as Figure 2 A hidden door handle is provided on a vehicle door and includes a base 1, a handle base 2 engaged with the base 1, a connecting structure 3 provided on the handle base 2, and a driving structure 4 connected to the connecting structure 3. The driving structure 4 drives the handle base 2 via the connecting structure 3, thereby realizing the opening and extension of the handle base 2 and the closing and concealment of the handle base 2.
[0030] Specifically, the base 1 supports the handle base 2 and various other structures. To accommodate the mounting of the connecting structure 3 and the drive structure 4, the base 1 includes a limiting slot 11 along its length. To facilitate positioning and assembly with the vehicle door, the base 1 is provided with a folded edge 12 that abuts the vehicle door. Furthermore, the base 1 has several positioning portions 13, each of which includes holes for positioning. These holes correspond to the positioning posts provided on the vehicle door.
[0031] Reference Figure 3The handle base 2 has a first connecting end 21 and a second connecting end 22 at its two ends in the longitudinal direction. The first connecting end 21 is engaged and slidably connected to the base 1, and the second connecting end 22 is engaged and slidably connected to the base 1. Driven by the driving structure 4, the driving structure 4 drives the connecting structure 3 to apply a pushing force and a pulling force to the first connecting end 21 and the second connecting end 22, thereby extending or retracting the handle base 2.
[0032] Reference Figure 3 、 Figure 4 、 Figure 5 as well as Figure 6 The connecting structure 3 includes a push plate 31 slidably connected to the base 1, a driving arm 32 connected to the push plate 31, and a connecting arm 33. The push plate 31 is mounted in a fixed position in the limiting chute 11 and is slidably connected to the limiting chute 11. In order to limit the push plate 31, the limiting chute 11 is provided with a plurality of limiting blocks 111 for cooperating with the push plate 31. When the push plate 31 abuts or disengages from the limiting blocks 111, the push plate 31 will move along a predetermined path in the limiting chute 11 under the action of the plurality of limiting blocks 111.
[0033] The driving arm 32 is provided at one end of the push plate 31 in the longitudinal direction and is engaged with the first connecting end 21. The connecting arm 33 is provided at the other end of the push plate 31 in the longitudinal direction and is engaged with the second connecting end 22. More specifically, the driving arm 32 has a driving adapter end 321 facing the push plate 31, and the connecting arm 33 has a connecting adapter end 331 facing the push plate 31. The push plate 31 has a corresponding first movable end 311 and a second movable end 312. The first movable end 311 is located at one side of the push plate 31 in the longitudinal direction and is connected to the driving adapter end 321. The first movable end 311 abuts against or disengages from the driving adapter end 321. The second movable end 312 is located at the other side of the push plate 31 in the longitudinal direction and is connected to the connecting adapter end 331.
[0034] In this embodiment, the drive adapter end 321 is tilted and has a first inclined surface and a second inclined surface. The shape of the first movable end 311 is adapted to the drive adapter end 321, and the first movable end 311 abuts or disengages with the first and second inclined surfaces. More specifically, the first movable end 311 is divided into an adapting wedge 3111 and a limiting crossbar 3112. The adapting wedge 3111 abuts or disengages with the first inclined surface, while the limiting crossbar 3112 abuts or disengages with the second inclined surface.
[0035] When the drive mechanism 4 drives the door handle to open, the push plate 31 drives the first movable end 311 to move, and the adapting wedge 3111 contacts the first inclined surface, thereby driving the drive arm 32 to move via the first inclined surface. When the drive mechanism 4 drives the door handle to close, the push plate 31 drives the first movable end 311 to move, and the limiting crossbar 3112 contacts the second inclined surface, thereby driving the drive arm 32 to move via the second inclined surface. This arrangement of the push plate 31 and the drive arm 32 effectively increases the force applied and force-bearing area between the first movable end 311 and the drive adapting end 321, ensuring that the drive arm 32 can move along a predetermined path.
[0036] The second movable end 312 is located on the side of the first movable end 311 away from the driving structure 4. When the second movable end 312 moves, the second movable end 312 will drive the connecting arm 33 to move through the connecting adapter end 331. In order to ensure that the connecting arm 33 moves along a predetermined path, the connecting structure 3 also includes a rotating shaft rocker arm 34 that is rotatably connected to the base 1. The rotating shaft rocker arm 34 has a positioning shaft 341. The positioning shaft 341 is sleeved with a torsion spring 342 that abuts against the base 1. The connecting adapter end 331 of the connecting arm 33 has a motion track groove 332. The rotating shaft rocker arm 34 is embedded in the motion track groove 332 and is slidably connected to the motion track groove 332. Under the action of the torsion spring 342, the positioning shaft 341 will be restricted from rotating, thereby limiting the position of the rotating shaft rocker arm 34. When the connecting adapter end 331 moves, the position of the rotating shaft rocker arm 34 is fixed, so that the connecting adapter end 331 moves along the predetermined path through its motion track groove 332.
[0037] The drive structure 4 is connected to one longitudinal end of the push plate 31 and includes a driver 41 and a drive push rod 42 disposed on the driver 41. The driver 41 is disposed on the side of the first movable end 311 away from the second movable end 312. One end of the drive push rod 42 is connected to the output shaft of the driver 41, and the other end of the drive push rod 42 is connected to the push plate 31. To facilitate connection with the drive push rod 42, the push plate 31 is provided with an adapter connecting groove 313 for mating with the drive push rod 42. The drive push rod 42 is fixedly mounted in the adapter connecting groove 313. Driven by the driver 41, the drive push rod 42 extends, thereby driving the push plate 31 to reciprocate back and forth. The reciprocating movement of the push plate 31 drives the drive arm 32 and the connecting arm 33 to move, thereby extending or retracting the handle base 2.
[0038] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0039] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
