As one of the parts that come into contact with drivers and passengers most frequently in daily use, the appearance and automation requirements of automotive door handles are getting higher and higher. Among them, hidden door handles have gradually become the trend. Hidden door handles can be divided into swing-out type and flush-out type. The most obvious advantage of hidden door handles is that they can improve the aesthetics of the vehicle in terms of appearance, thereby giving the vehicle a sense of luxury.

Specific embodiments

[0033] Next, in combination with specific embodiments, the present application will be further described. It should be noted that, on the premise of no conflict, the following described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0034] In the description of the present application, it should be noted that for the orientation terms, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the indicated orientation and positional relationship are based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0035] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence.

[0036] One aspect of the present application provides a swing-out hidden door handle, as Figures 1 to 13 shown. One preferred embodiment includes a base 1, a driving mechanism 3, and a handle 2. The base 1 is fixedly arranged inside the door body. One end of the handle 2 is hinged to the base 1, and at the same time, the hinged end of the handle 2 can be connected to the base 1 through a torsion spring. The driving mechanism 3 is installed on the base 1, and the driving mechanism 3 can cooperate with the handle 2 and the door lock mechanism (not shown) respectively. Initially, the handle 2 can be retracted inside the door under the elastic force of the torsion spring for hiding. When opening the door is required, the opening process includes a first process and a second process. Among them, the first process: the driving mechanism 3 can drive the handle 2 to rotate around the hinged position and swing out to the outside of the door. The second process: the driving mechanism 3 can continue to drive to realize automatic unlocking of the door lock mechanism, or manual unlocking of the door lock mechanism can be realized by pulling the handle 2.

[0037] It can be understood that everyone has different habits of unlocking the car door when driving a vehicle. By providing two unlocking methods, automatic unlocking and manual unlocking, the present application can improve the user experience.

[0038] At the same time, in daily life, most vehicles need to be manually unlocked. For children, this is inconvenient to operate. Therefore, by setting the automatic unlocking method, manual operation is not required, making it more labor-saving and convenient to open the door.

[0039] In this embodiment, through the cooperation of the driving mechanism 3 with the handle 2 and the door lock mechanism respectively, the door lock mechanism can perform independent unlocking operations through the driving mechanism 3 and the handle 2 respectively. That is, through the mutual cooperation of the driving mechanism 3 and the handle 2 with the door lock mechanism respectively, an unlocking structure for unlocking the door lock mechanism in multiple ways can be formed.

[0040] It is understandable that the door lock mechanism is a prior art, and its structure and installation method are well known to those skilled in the art.

[0041] In this embodiment, as Figure 3 , Figure 4 and Figures 7 to 13 shown, a receiving cavity 100 is provided on the front surface of the base 1, and the front end surface of the receiving cavity 100 is flush with the door body; the shape of the receiving cavity 100 is adapted to the shape of the handle 2, and one end of the handle 2 is hinged to one end of the receiving cavity 100. Initially, the handle 2 can be hingedly received in the receiving cavity 100 under the elastic force of the torsion spring to ensure that the handle 2 is flush with the end surface of the door body, thereby improving the overall aesthetics of the door body and at the same time reducing wind resistance. A through hole 110 is provided on one side of the receiving cavity 100 close to the hinge position, and an extension portion 23 is provided on the handle 2. The extension portion 23 can pass through the through hole 110 and extend to the back of the base 1 and cooperate with the driving mechanism 3 and the door lock mechanism installed on the back of the base 1.

[0042] It is understandable that by providing the receiving cavity 100 on the base 1, the processing difficulty of providing the receiving cavity 100 on the door body can be reduced, and at the same time, the detachable base 1 can also facilitate the installation of the handle 2.

[0043] Specifically, as Figure 3 and Figure 4 shown, a second hinge portion 21 is provided at one end of the handle 2, and a first hinge portion 111 is provided at one end of the receiving cavity 100; the handle 2 and the receiving cavity 100 are hinged through the mutual cooperation of the first hinge portion 111 and the second hinge portion 21.

[0044] It is understandable that there are various structures for the first hinge portion 111 and the second hinge portion 21, including but not limited to the following three.

[0045] Structure 1: As Figure 3 and Figure 4 shown, both the first hinge portion 111 and the second hinge portion 21 are hinge holes; thus, the hinge holes between the handle 2 and the receiving cavity 100 are aligned with each other and connected by a hinge rod to ensure that the handle 2 can rotate around the hinge position and extend out of the receiving cavity 100.

[0046] Structure 2: The first hinge portion 111 is a hinge hole, and the second hinge portion 21 is a hinge rod; thus, the handle 2 and the receiving cavity 100 are hinged to each other through the hinge rod and the hinge hole to ensure that the handle 2 can rotate around the hinge position and extend out of the receiving cavity 100.

[0047] Structure Three: The first hinge part 111 is a hinge rod, and the second hinge part 21 is a hinge hole; thus, the handle 2 and the storage cavity 100 are hinged to each other through the hinge rod and the hinge hole, so as to ensure that the handle 2 can rotate around the hinge position and extend out of the storage cavity 100.

[0048] One embodiment of the present application is as Figure 1 , Figure 4 , Figure 5 and Figures 7 to 13 shown, the swing-out hidden door handle further includes an unlocking component 4; the unlocking component 4 is rotatably mounted on the back of the base 1 through a torsion spring; the unlocking component 4 is respectively provided with a connecting part 42 and a driving part 43, and both the connecting part 42 and the driving part 43 deviate from the mounting position of the unlocking component 4. The connecting part 42 is used to connect with the door lock mechanism, so that the unlocking component 4 drives the connecting part 42 to pull the door lock mechanism to unlock by rotating around the mounting position. Initially, both the driving mechanism 3 and the handle 2 are spaced from the driving part 43; when the first process is completed, both the driving mechanism 3 and the handle 2 can be in contact and cooperation with the driving part 43, so that when the second process is carried out, the unlocking component 4 can be driven to rotate by the extrusion of the driving mechanism 3 on the driving part 43, thereby realizing that the connecting part 42 drives the door lock mechanism to automatically unlock; or the unlocking component 4 can be driven to rotate by pulling the handle 2, thereby realizing that the connecting part 42 drives the door lock mechanism to manually unlock.

[0049] In this embodiment, as Figure 2 , Figure 5 , Figure 8 , Figure 10 , Figure 11 and Figure 13 shown, the unlocking component 4 is provided with a second rotating part 41, and the back of the base 1 is provided with a first rotating part 130; the unlocking component 4 is rotationally connected through the second rotating part 41 and the first rotating part 130.

[0050] Specifically, the first rotating part 130 is a rotating rod, and the second rotating part 41 is a rotating hole; then the torsion spring is sleeved on the first rotating part 130 and is respectively connected to the base 1 and the unlocking component 4. Or, the first rotating part 130 is a rotating hole, and the second rotating part 41 is a rotating rod; then the torsion spring is sleeved on the second rotating part 41 and is respectively connected to the base 1 and the unlocking component 4.

[0051] In this embodiment, as Figure 1 , Figures 6 to 13As shown in the figure, the drive mechanism 3 is located at the end near the hinged position of the handle 2. The drive mechanism 3 includes an actuator 31 and a push rod 32 connected to the output end of the actuator 31. Initially, the end of the push rod 32 away from the actuator 31 can be spaced from the drive part 43; at the same time, the push rod 32 can cooperate with the extension part 23. When performing the first process, the push rod 32 moves in the direction close to the drive part 43 under the drive of the actuator 31 until it contacts; and during the movement, the push rod 32 can drive the extension part 23 to drive the handle 2 to rotate around the hinged position and swing out of the storage cavity 100. When performing the second process, the push rod 32 can move under the continuous drive of the actuator 31 and squeeze the drive part 43, so that the unlocking component 4 rotates around the rotation installation position under the driving force of the push rod 32, thereby unlocking the door lock mechanism.

[0052] It can be understood that the actuator 31 is a prior art, and its specific structure and working principle are well known to those skilled in the art. The actuator 31 is generally one of a cylinder, a hydraulic cylinder or a linear motor.

[0053] At the same time, when the car door needs to be opened, the actuator 31 can be triggered to start by means of buttons, fingerprints, sensor induction, voice control, etc. Thus, the actuator 31 can first drive the handle 2 to rotate from the state flush with the door body and swing out of the car door to reach the raised welcome state; subsequently, the door lock mechanism unlocks and opens the car door, and the unlocking method can be the automatic drive of the actuator 31 or the manual operation of pulling the handle 2.

[0054] Therefore, during the process of the handle 2 extending out of the car door, the door lock mechanism is always in a locked state. Thus, in this application, by initially spacing the push rod 32 connected to the output end of the actuator 31 from the drive part 43 of the unlocking component 4, when the actuator 31 drives the handle 2 to extend through the push rod 32, the push rod 32 can avoid triggering the unlocking of the door lock mechanism by not contacting the drive part 43. At the same time, by controlling the stroke of the drive push rod 32 by the actuator 31 to achieve contact with the drive part 43, interference between the unlocking component 4 and the push rod 32 can be avoided during the manual unlocking process of driving the unlocking component 4 through the handle 2.

[0055] In this embodiment, as Figure 2 shown, an installation cavity 140 is provided on the back of the base 1, and the actuator 31 is detachably installed in the installation cavity 140 for easy installation of the actuator 31.

[0056] In this embodiment, as Figure 2 、 Figure 3 and Figure 6As shown, a guiding groove 120 is provided on the base 1, and the extending direction of the guiding groove 120 is parallel to the rotating direction of the handle 2; a guiding block 322 is provided on the push rod 32, and the push rod 32 can be slidably engaged with the guiding groove 120 through the guiding block 322, so that when the push rod 32 moves under the drive of the actuator 31, the moving direction of the push rod 32 can be ensured not to deviate.

[0057] In this embodiment, as Figure 4 and Figure 6 shown, a first engaging portion 22 is provided on the extending portion 23, and a second engaging portion 320 is provided on the push rod 32. When performing the first process, the handle 2 can be driven to rotate around the hinged position and extend out of the storage cavity 100 through the mutual extrusion and engagement between the second engaging portion 320 and the first engaging portion 22.

[0058] It can be understood that there are various structures for the first engaging portion 22 and the second engaging portion 320, including but not limited to the following two.

[0059] Structure 1: The first engaging portion 22 and / or the second engaging portion 320 is a wedge block; when performing the first process, the push rod 32 and the extending portion 23 can be squeezed through the wedge block to drive the handle 2 to rotate around the hinged position and swing out of the storage cavity 100.

[0060] Structure 2: The first engaging portion 22 and / or the second engaging portion 320 has a convex portion; when performing the first process, the push rod 32 and the extending portion 23 are squeezed through the convex portion to drive the handle 2 to rotate around the hinged position and swing out of the storage cavity 100.

[0061] In one embodiment of the present application, as Figures 7 to 13 shown, the rotation plane of the unlocking member 4 is perpendicular to the rotation plane of the handle 2. Thus, initially, the extending portion 23 can be spaced apart from the driving portion 43; when performing the first process, the extending portion 23 can approach and contact the driving portion 43 as the handle 2 rotates and swings out; when performing the second process, by pulling the handle 2 to drive the extending portion 23 to squeeze the driving portion 43, the unlocking member 4 is further driven to rotate to achieve manual unlocking.

[0062] It can be understood that the rotation plane of the unlocking member 4 can also be parallel to the rotation plane of the handle 2. However, this will increase the overall size of the present application; thus, by vertically arranging the rotation plane of the unlocking member 4 and the rotation plane of the handle 2, the overall size can be reduced, and when the present application is installed in the door body, interference with other components in the door body can be avoided.

[0063] In this embodiment, as Figure 5 、 Figure 8 、 Figure 10 、Figure 11 and Figure 13 As shown in Figure 13 , the driving part 43 includes a first driving section 431 and a second driving section 432; wherein, the second driving section 432 is close to the installation position of the unlocking member 4, and the first driving section 431 is far from the installation position of the unlocking member 4. The driving mechanism 3 can be in extrusion cooperation with the first driving section 431 through the push rod 32 to drive the unlocking member 4 to rotate and unlock; the handle 2 can be in extrusion cooperation with the second driving section 432 through the extension part 23 to make the unlocking member 4 rotate and unlock.

[0064] It can be understood that when the unlocking member 4 rotates to unlock, the closer the extrusion position of the driving part 43 is to the installation position of the unlocking member 4, the shorter the driving distance required for the unlocking member 4 to rotate the same angle. In this application, the stroke of the push rod 32 can be unrestricted, but the pulling angle of the handle 2 should not be too large. An excessive deflection angle is not convenient for the user to pull and is also likely to cause slipping. Therefore, by matching the extension part 23 with the second driving section 432 close to the installation position of the unlocking member 4, unlocking can be achieved when the handle 2 is pulled at a relatively small angle.

[0065] Specifically, as Figure 4 shown, an arc-shaped convex block 230 is provided at the end of the extension part 23. The extension part 23 can drive the unlocking member 4 to drive the door lock mechanism to rotate and unlock through the extrusion cooperation of the convex block 230 with the second driving section 432.

[0066] It can be understood that by providing the arc-shaped convex block 230, the friction force generated between the extension part 23 and the unlocking member 4 when driving the unlocking member 4 to rotate can be reduced. Furthermore, the wear of the extension part 23 can be increased, and at the same time, the noise generated when the handle 2 unlocks can be reduced.

[0067] In this embodiment, as Figure 6 、 Figure 10 and Figure 11 shown, a top block 321 is provided at the end of the push rod 32 far from the actuator 31. Thus, when automatically unlocking in the second process, the push rod 32 can drive the unlocking member 4 to rotate and unlock by extruding the first driving section 431 on the driving part 43 through the top block 321.

[0068] It can be understood that by providing the cylindrical top block 321, the friction force generated when the push rod 32 is in extrusion with the driving part 43 can be reduced, so that it is more convenient for the unlocking member 4 to rotate during automatic unlocking, and at the same time, the noise generated during automatic unlocking can be reduced.

[0069] For easy understanding, the door opening process of this application will be described in detail in the form of parameters.

[0070] (1) Initially; as Figure 7and Figure 8 As shown, at this time, the handle 2 is retracted into the storage cavity 100, and the outer side surface of the handle 2 is flush with the outer side of the door body, thus reaching a hidden state, making the door body have better aesthetics and also reducing the wind resistance during driving.

[0071] At this time, the distance between the top block 321 provided on the push rod 32 and the first driving section 431 on the driving part 43 is X; at the same time, the distance between the bump 230 provided on the extension part 23 and the second driving section 432 on the driving part 43 is Y.

[0072] (2) Perform the first process; as Figure 9 and Figure 10 As shown, the actuator 31 is triggered to start. The actuator 31 can drive the push rod 32 to move a distance of X in the direction close to the unlocking component 4 through the output end, so that the top block 321 at the end of the push rod 32 just abuts against the first driving section 431 of the driving part 43 on the unlocking component 4.

[0073] At the same time, during the movement of the push rod 32, the push rod 32 can drive the handle 2 to rotate outward by an angle of α around the first hinge part 111 through the extrusion fit of the second cooperation part 320 provided on the push rod 32 and the first cooperation part 22 provided on the extension part 23, so that the handle 2 assumes a raised welcome gesture for the convenience of the user to hold. During this process, the torsion spring connected to the handle 2 is in a compressed state.

[0074] (3) Perform the second process; if automatic unlocking is adopted, as Figure 11 As shown; under the continuous drive of the output end of the actuator 31, the push rod 32 can continue to move a distance of Y in the same direction; thus, through the abutting fit of the top block 321 and the first driving section 431, the first driving section 431 can be driven to move a distance of Y synchronously; through the movement of the first driving section 431, the unlocking component 4 can be driven to rotate around the first rotating part 130, and then the door lock mechanism can be pulled to unlock through the synchronous rotation of the connecting part 42. During this process, the torsion spring connected to the unlocking component 4 is in a compressed state; at the same time, the push rod 32 always maintains the fit with the extension part 23, so that the handle 2 remains stationary during the automatic unlocking process.

[0075] If manual unlocking is adopted, as Figure 12 and Figure 13As shown in the figure; during the completion of the first process, the handle 2 is pulled, and the handle 2 can rotate again by an angle β around the first hinge portion 111; during the rotation of the handle 2 again, the extension portion 23 can rotate synchronously with the handle 2, and thus the extension portion 23 can drive the unlocking member 4 to rotate around the first rotating portion 130 through the extrusion fit between the bump 230 and the second driving section 432 on the driving portion 43, and then drive the door lock mechanism to unlock through the synchronous rotation of the connecting portion 42. During this process, the torsion spring connected to the unlocking member 4 is in a compressed state.

[0076] (4) The reset process of the handle 2 after the vehicle door is opened; if the second process uses automatic unlocking, the actuator 31 drives the push rod 32 to move back in the opposite direction by a distance of X + Y to return to the initial position. During the reset of the push rod 32, initially, the unlocking member 4 can rotate reversely to the initial position under the reset elastic force of the torsion spring, so that the door lock mechanism can be self-locked through the connecting portion 42; as the push rod 32 continues to move, the push rod 32 gradually disengages from the extension portion 23, so that the handle 2 rotates reversely under the reset elastic force of the torsion spring until it retracts into the receiving cavity 100 on the base 1 to reach the hidden state again.

[0077] If the second process uses manual unlocking, the handle 2 is released. The handle 2 can rotate reversely under the reset elastic force of the torsion spring, and during the process of the handle 2 rotating reversely by an angle β, the unlocking member 4 also rotates reversely to the initial position under the elastic force of the torsion spring, so that the door lock mechanism can be self-locked through the connecting portion 42; subsequently, the actuator 31 can drive the push rod 32 to move back to the initial position, so that during the movement of the push rod 32, the handle 2 can continue to rotate reversely by an angle α under the reset elastic force of the torsion spring until it retracts into the receiving cavity 100 on the base 1 to reach the hidden state again.

[0078] It can be understood that during the reset process of manual unlocking, the actuator 31 can also be reset before the handle 2 is released, so that the handle 2 can directly rotate reversely by an angle α + β to realize the synchronous reset of the unlocking member 4 and the handle 2. However, the reverse rotation stroke of the handle 2 is too large and there is no buffering mechanism, which may cause impact with the base 1, thereby affecting the user experience and increasing noise at the same time. Therefore, the manual unlocking reset process of the present application preferably adopts the above step (4).

[0079] Another aspect of the present application provides a vehicle, including the above-mentioned swing-out hidden door handle.

[0080] It can be understood that the swing-out hidden door handle in the present application can be applied not only to vehicles but also to other fields.

[0081] The foregoing has described the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements, and these changes and improvements all fall within the scope of the present application claimed. The scope of protection required by the present application is defined by the appended claims and their equivalents.
