When door handle 20 is rotated from the first position to the second position, door handle 20 drives transmission member 40 to move. When door handle 20 is in the second position, transmission member 40 abuts the switch element 30, and switch element 30 generates an electric signal for controlling the unlocking of door 300.
In the aforementioned door handle apparatus 100 for a vehicle, door 300, and vehicle 200, when door handle 20 is rotated to the second position outside housing recess 13, door handle 20 can cause, through transmission member 40, switch element 30 to generate an electric signal for controlling the unlocking of door 300. Such simple operations enables door 300 to be opened in an electric manner more conveniently.
Specifically, support structure 10 is a carrier of door handle apparatus 100 for a vehicle, and support structure 10 may be used to carry other components of door handle apparatus 100 for a vehicle. Support structure 10 may have a plate shape, an irregular shape, or the like, and the specific shape of support structure 10 is not limited herein. In an embodiment of the present invention, in order to make support structure 10 easy to carry other components, support structure 10 has an irregular shape. Support structure 10 can be made of plastic, metal or other materials. For example, when support structure 10 is made of plastic, support structure 10 can be formed by an injection molding process.
In an embodiment of the present invention, first side 11 and second side 12 of support structure 10 respectively extend along the thickness direction of support structure 10. In other words, first side 11 and second side 12 of support structure 10 are respectively located on opposite sides of support structure 10 in the thickness direction. Housing recess 13 is a recessed part on support structure 10, and the volume of housing recess 13 is adapted to the volume of door handle 20 so that door handle 20 can be received in housing recess 13. In addition, the shape of housing recess 13 is adapted to the shape of door handle 20, allowing a more compact matching of housing recess 13 and door handle 20. For example, door handle 20 may have an oval shape as a whole, and housing recess 13 may also have an oval shape.
Door handle 20 is an operating component of door handle apparatus 100 for a vehicle, and users can open door 300 of vehicle 200 by operating door handle 20. Along the length of door handle 20, door handle 20 includes first end 21 and second end 22, and first rotation shaft 14 is provided between and passes through first end 21 and second end 22. In an embodiment of the present invention, first rotation shaft 14 is arranged closer to second end 22 than first end 21.
First rotation shaft 14 is located in housing recess 13, and first rotation shaft 14 and support structure 10 may be separately formed structures. First rotation shaft 14 can be detachably mounted on support structure 10. In an example, when assembling door handle apparatus 100 for a vehicle, door handle 20 can be placed in housing recess 13 first, and then first rotation shaft 14 is inserted into support structure 10 and door handle 20 in sequence, to complete the installation of door handle 20.
It can be understood that during the rotation of door handle 20 from the first position to the second position, first end 21 of door handle 20 turns out of housing recess 13, and second end 22 of door handle 20 turns into housing recess 13.
In an embodiment of the present invention, door handle 20 includes main body 23 and handle cover 24 covering and arranged on the main body 23, as shown in FIG. 2 and FIG. 3.

Handle cover 24 can be formed with a smooth outer surface by paint spraying or other processes, so that door handle 20 is more artistic.
Switch element 30 is an electrical component, and switch element 30 can generate an electric signal when it is touched or approached. Switch element 30 may be a micro switch, a proximity sensor, or other components. Switch element 30 can be installed on support structure 10 by means of screws, buckles, or the like. Switch element 30 is located on second side 12 of support structure 10, so that the spaces on support structure 10 can be fully utilized to prevent switch element 30 from interfering with door handle 20, making door handle apparatus 100 for a vehicle more compact.
Transmission member 40 is a force transmitting component of door handle apparatus 100 for a vehicle, and transmission member 40 can transmit the force from door handle 20 to switch element 30. Transmission member 40 is located on second side 12 of support structure 10 so as to prevent transmission member 40 from interfering with door handle 20. Transmission member 40 can be made of plastic or other materials. The structure and shape of transmission member 40 are not specifically limited. In an embodiment of the present invention, transmission member 40 has an irregular shape.
Referring to FIG. 5, FIG. 5 shows the position of transmission member 40 when door handle 20 is in the first position. As shown in FIG. 5, when door handle 20 is in the first position, transmission member 40 is spaced apart from switch element 30, and at this point, switch element 30 is not triggered. Referring to FIG. 6 and FIG. 7, when door handle 20 is in the second position, transmission member 40 abuts switch element 30, and at this point, switch element 30 is triggered to generate an electric signal. The electric signal generated by switch element 30 can be transmitted to a controller of vehicle 200, and the controller can control corresponding electric component to unlock door 300 in an electric manner, so that door 300 can be opened when unlocked.
In some embodiments, when door handle 20 is rotated from the first position to the second position, the angular distance that door handle 20 travels is within the range of 7°-13°. In other words, door handle 20 reaches the second position after rotating 7°-13° from the first position. For example, when door handle 20 is rotated from the first position to the second position, the angle that door handle 20 has rotated may be 7°, 8.5°, 9°, 10°, 12.5°, or 13°.
It can be understood that, in the second position, since transmission member 40 abuts switch element 30, switch element 30 can form a reaction force on transmission member 40, and the force can be transmitted to door handle 20. Therefore, when users operate door handle 20, they can perceive that switch element 30 is triggered.
Referring to FIG. 3 and FIG. 5, in some embodiments, door handle apparatus 100 for a vehicle includes pushing member 50, and pushing member 50 connects second end 22 of door handle 20 to transmission member 40. Pushing member 50 passes through support structure 10. Door handle 20 drives transmission member 40 to move through pushing member 50.
In this way, pushing member 50 facilitates door handle 20 to drive transmission member 40 to move. Specifically, pushing member 50 has a long strip shape. Pushing member 50 and main body 23 of door handle 20 may be in an integral structure, in other words, pushing member 50 and main body 23 of door handle 20 cannot be detached. Pushing member 50 abuts transmission member 40, so that transmission member 40 can be pushed to move.
Referring to FIG. 4, in some embodiments, transmission member 40 is rotatably arranged on support structure 10 through second rotation shaft 41, and door handle 20 is operable to drive transmission member 40 to rotate. In this way, transmission member 40 can be arranged on support structure 10 in a rotating manner, so that the movement mode of transmission member 40 is easier to control.
Specifically, second rotation shaft 41 and support structure 10 may be in an integral structure. The axial direction of second rotation shaft 41 is the same as the thickness direction of support structure 10. Second rotation shaft 41 and pushing member 50 are arranged at a predefined distance from each other, so that transmission member 40 can form a rotational torque, and thus pushing member 50 can push transmission member 40 to rotate during the movement.
Referring to FIG. 4, in some embodiments, door handle apparatus 100 for a vehicle includes elastic member 60 arranged on support structure 10, and elastic member 60 is spaced apart from switch element 30. Door handle 20 can move from the second position to a third position, and the second position is between the first position and the third position. During the rotation of door handle 20 from the second position to the third position, transmission member 40 rotates and remains in contact with switch element 30. When door handle 20 is in the third position, transmission member 40 elastically abuts elastic member 60.
In other words, during the rotation of door handle 20, it can rotate from the first position to the second position and the third position in sequence. The rotation angle of door handle 20 from the first position to the second position is smaller than the rotation angle of the door handle from the first position to the third position.
As shown in FIG. 8, when door handle 20 is in the third position, transmission member 40 elastically abuts elastic member 60, so that elastic member 60 can act as a soft limiting structure to transmission member 40, and elastic member 60 can form feedback to door handle 20 through transmission member 40, reminding users that switch element 30 has been triggered and door 300 is unlocked during the rotation of door handle 20, so as to facilitate users to unlock door 300 with door handle 20.
As shown in FIG. 4, in some embodiments, elastic member 60 includes abutting member 61 and first elastic member 62. Abutting member 61 is rotatably arranged on support structure 10 through third rotation shaft 63. First elastic member 62 is connected to abutting member 61. When door handle 20 is in the third position, transmission member 40 abuts abutting member 61, and first elastic member 62 applies a first restoring force to abutting member 61.
In this way, first elastic member 62 can transmit feedback to door handle 20 through abutting member 61 and transmission member 40, and can make abutting member 61 restore to the initial position after being rotated. Specifically, abutting member 61 may have an irregular shape. Abutting member 61 is sheathed on third rotation shaft 63 so that abutting member 61 can rotate relative to support structure 10. Abutting member 61 and switch element 30 contact transmission member 40 respectively at different parts.
First elastic member 62 can be a spring, an elastic block, or other elastic member. In an embodiment of the present invention, first elastic member 62 is a torsion spring, and the torsion spring is sheathed on the third rotation shaft 63. The torsion spring can provide abutting member 61 with the first restoring force, so that abutting member 61 can restore to the initial position.
In some embodiments, when door handle 20 is rotated from the first position to the third position, the angular distance that the door handle 20 travels is within the range of 14°-16°. In other words, after door handle 20 is rotated for an angle range of 14°-16°, transmission member 40 abuts elastic member 60. Rhe rotation angle of door handle 20 is appropriate and is convenient for users to operate. In an example, when door handle 20 is rotated from the first position to the third position, the angle that door handle 20 has rotated may be 14°, 15°, or 16°.
Referring to FIG. 9 and FIG. 10, in some embodiments, limiting structure 15 is provided in housing recess 13. Door handle 20 can move from the third position to a fourth position, and the third position is between the second position and the fourth position. During the rotation of door handle 20 from the third position to the fourth position, transmission member 40 rotates and remains in contact with elastic member 60. When door handle 20 is in the fourth position, second end 22 of door handle 20 abuts limiting structure 15.
In this way, when door handle 20 is located at the fourth position, limiting structure 15 can limit door handle 20 from continuing to rotate, so as to limit door handle 20 from overly rotating, which is convenient for users to use. Specifically, limiting structure 15 is first protrusion 151 formed in housing recess 13, and second end 22 of door handle 20 may form second protrusion 25. First protrusion 151 abuts second protrusion 25, so that door handle 20 can be limited from continuing to rotate. The surface on which second protrusion 25 abuts first protrusion 151 may be an inclined surface.
In some embodiments, when the door handle is rotated from the first position to the fourth position, an angular distance that the door handle travels is within the range of 20°-24°. In other words, after door handle 20 is rotated for an angle in the range of 20°-24°, limiting structure 15 abuts second end 22 of door handle 20. The rotation angle of door handle 20 is appropriate and is convenient for users to operate. In an example, when door handle 20 is rotated from the first position to the fourth position, the angle door handle 20 has rotated may be 20°, 21°, 22°, or 24°.
Referring to FIG. 4 and FIG. 9, in some embodiments, transmission member 40 forms arc rack 42 concentrically arranged with second rotation shaft 41. Door handle apparatus 100 for a vehicle includes gear 70 rotatably arranged on support structure 10, and gear 70 meshes with arc rack 42.
In this way, transmission member 40 meshes with gear 70 through arc rack 42 so that the rotation of transmission member 40 can be more stable. Specifically, gear 70 is spaced apart from switch element 30 and abutting member 61. Abutting member 61 is located between switch element 30 and abutting member 61, so that the components of door handle apparatus 100 for a vehicle are reasonably arranged in place, such that door handle apparatus 100 for a vehicle is more compact.
Referring to FIG. 4, in some embodiments, door handle apparatus 100 for a vehicle further includes second elastic member 80 connecting support structure 10 and transmission member 40, and first elastic member 62 is used to apply a second restoring force to transmission member 40. The second restoring force enables transmission member 40 to move to restore door handle 20 to the first position.
In this way, door handle 20 can be restored into housing recess 13 after being rotated, which is convenient for users to use. Specifically, second elastic member 80 can be a spring, an elastic block, or other elastic members. In an embodiment of the present invention, second elastic member 80 is a torsion spring, and the torsion spring is sheathed on second rotation shaft 41. The torsion spring can provide transmission member 40 with a second restoring force, so that transmission member 40 can restore to the initial position, driving door handle 20 to restore to the first position and be received in housing recess 13.
Referring to FIG. 10, in some embodiments, the bottom surface of housing recess 13 is provided with keyhole 16, and keyhole 16 is arranged associated with first end 21 of door handle 20. In this way, keyhole 16 can allow key 102 to insert into door 300 to unlock door 300 in a mechanical manner. As discussed above, when door handle 20 is in the fourth position, the angle of door handle 20 has rotated is the largest, and meanwhile the distance between first end 21 and housing recess 13 is relatively longer, so that key 102 can be inserted into keyhole 16.
Referring to FIG. 1 again, according to an embodiment of the present invention, door 300 further includes door body 310. Door handle apparatus 100 for a vehicle is provided on door body 310. The outer surface of door handle 20 is flush with the outer surface of door body 310, or the outer surface of door handle 20 is recessed on the outer surface of door body 310. In this way, door handle 20 can be concealed in door 300, which not only improves the aesthetics of door 300, but also reduces the resistance of vehicle 200 during travel.
According to an embodiment of the present invention, vehicle 200 includes body frame 210 and door 300, and door 300 is provided on body frame 210. In this way, door handle apparatus 100 for a vehicle can make the unlocking of door 300 of vehicle 200 more convenient, which helps to improve the user experience.
