Detailed Description

The present application is further described below with reference to specific embodiments, and it should be noted that, without conflict, any combination between the embodiments described below or between the technical features may form a new embodiment.

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

It is noted that the terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

One aspect of the present application provides a concealed door handle, as shown in fig. 1-18, wherein a preferred embodiment includes a base, a drive mechanism 3, and a handle 2. The base is fixedly arranged on the door body, and the driving mechanism 3 is arranged on the base. The drive mechanism 3 may be coupled to the handle 2 and the door lock mechanism (not shown), respectively. When the door body is closed initially, the handle 2 can be retracted into the door body through the driving mechanism 3 to be hidden; when the door needs to be opened, the opening process comprises a first process and a second process; wherein the first process: the driving mechanism 3 can drive the handle 2 to extend out of the door in parallel; the second process: the door lock mechanism may be unlocked by continued driving of the drive mechanism 3, or may be unlocked by manually pulling the handle 2.

It can be understood that the unlocking habit for the door is different when everyone drives the vehicle; according to the method and the device, the experience of the user can be improved by providing two modes of automatic unlocking and manual unlocking.

Meanwhile, in daily life, most vehicles need to be manually unlocked; this is inconvenient for children to handle; therefore, by setting the automatic unlocking mode, manual operation is not needed, and the door is opened more conveniently and more labor-saving.

In this embodiment, the driving mechanism 3 is connected to the handle 2 and the door lock mechanism, so that the door lock mechanism can perform mutually independent unlocking operations through the driving mechanism 3 and the handle 2. Namely, the driving mechanism 3 and the handle 2 are respectively matched with the door lock mechanism, so that the unlocking structure of the door lock mechanism can be formed.

It will be appreciated that door latch mechanisms are known in the art, and their construction and manner of installation are well known to those skilled in the art.

In this embodiment, as shown in fig. 1, the base includes an upper base 110 and a lower base 120 detachably connected to each other; the upper base 110 and the lower base 120 are both fixedly installed in the door body. The installation of the driving mechanism 3 and the handle 2 can be facilitated by the detachable upper base 110 and the lower base 120.

In the present embodiment, as shown in fig. 2 to 18, the drive mechanism 3 includes an actuator 31, an extending mechanism, and an unlocking member 37. The unlocking member 37 is used for connecting the door lock mechanism; the extending mechanism is respectively matched and connected with the handle 2 and the unlocking component 37; the actuator 31 can cooperate with the extension mechanism and the unlocking member 37 via the output. Initially, the output of the actuator 31 is spaced from the unlocking member 37; when the first process is performed, the actuator 31 can move in a direction close to the unlocking member 37 by driving the output end, so that the extending mechanism can be driven to extend the handle 2 to the outside of the door, and when the handle 2 extends to the outside of the door, the output end of the actuator 31 just contacts with the unlocking member 37. When the second process is performed, the actuator 31 may drive the unlocking member 37 to unlock by continuously driving the output end to move; or pull the handle 2 to manually actuate the extension mechanism to move the unlocking member 37 for unlocking.

It will be appreciated that the actuator 31 is conventional and that its specific construction and principle of operation are well known to those skilled in the art. The actuator 31 is typically one of a pneumatic cylinder, a hydraulic cylinder, or a linear motor.

Meanwhile, when the vehicle door needs to be opened, the actuator 31 can be triggered to start through the key, the fingerprint, the sensor induction, the voice control and the like, so that the actuator 31 can horizontally extend out of the vehicle door from a state that the handle 2 is flush with the vehicle door to reach a welcome state; the door lock mechanism then unlocks the door open, either by automatic actuation of the actuator 31 or by manual pulling of the handle 2.

Therefore, the door lock mechanism is always in a locked state during the process of extending the handle 2 out of the door. Therefore, in the present application, by initially spacing the output end of the actuator 31 from the unlocking member 37, the actuator 31 can avoid the door lock mechanism from being triggered to unlock by the non-contact with the unlocking member 37 during the process of driving the handle 2 to extend through the extending mechanism. Meanwhile, the unlocking member 37 is prevented from interfering with the actuator 31 during manual unlocking by driving the unlocking member 37 by the handle 2 through the stroke contact of the actuator 31 and the unlocking member 37.

In one embodiment of the present application, as shown in fig. 2, 4, 7, 9, 10 and 12 to 18, the extending mechanism includes an active arm 33 and a connecting arm 36 that are spaced apart. One end of the driving arm 33 and one end of the connecting arm 36 are hinged with the base; the other ends of the active arm 33 and the connecting arm 36 are hinged to the two ends of the inner side of the handle 2. The driving arm 33 is close to the actuator 31 and connected to the base through a torsion spring, and the driving arm 33 may cooperate with an output end of the actuator 31, so that the driving arm 33 may deflect around a position where the driving arm is hinged to the base under the driving of the actuator 31. Four-bar mechanisms can be formed among the active arm 33, the connecting arm 36, the base and the handle 2, so that in the first process, the handle 2 can be driven to horizontally extend out of the door body in a posture parallel to the door body through deflection of the active arm 33, and the use of a user is met in a welcome state.

It will be appreciated that the four-bar mechanism has good stability and that the parallel extension of the handle 2 can be achieved by forming the four-bar mechanism between the master arm 33, the link arm 36, the base and the handle 2.

In this embodiment, as shown in fig. 3, 4, and 12 to 18, the driving arm 33 is provided with a protrusion 330, and the output end of the actuator 31 is provided with a driving portion 320 for engaging with the protrusion 330. Thus, when the first process is performed, the actuator 31 can drive the driving portion 320 to move synchronously through the output end, and in the process that the driving portion 320 moves, the driving portion 320 can generate an extrusion force on the protruding portion 330, and then the driving arm 33 deflects through the extrusion force to drive the connecting arm 36 to deflect synchronously through the four-bar linkage, so that the handle 2 can keep the parallel posture to extend out. And the torsion spring connected to the active arm 33 is always in a compressed state in the first and second processes; therefore, when the actuator 31 is reset after the vehicle door is opened, the active arm 33 is reset and deflected under the elastic action of the torsion spring, and then the handle 2 is driven by the four-bar mechanism to be reset and contracted to be in a hidden state flush with the door body.

Specifically, as shown in fig. 2 and 3, the output end of the actuator 31 is connected to a push block 32, and the driving unit 320 is provided at the end of the push block 32. The pushing block 32 can facilitate the processing of the driving part 320. Meanwhile, the push block 32 can ensure that the arranged driving part 320 meets the size requirement of use.

In this embodiment, as shown in fig. 2, 3, 5, 7, 12 and 14. The driving mechanism 3 further comprises a first connecting rod 341 slidably disposed on the base, and one end of the first connecting rod 341 is hinged to a first push rod 321 disposed on a push block 32 connected to the output end of the actuator 31; the other end of the first link 341 is provided with a locking groove 3411, and the connecting arm 36 is provided with a locking block 361. Initially, the latching groove 3411 is spaced from the latching block 361; when the first process is performed, the first link 341 may move in synchronization with the push block 32, so that the locking groove 3411 may move in a direction to approach the locking block 361 with the first link 341 until they contact each other; thus, in the second process, the connecting arm 36 can be unidirectionally locked by the engagement of the locking groove 3411 with the locking block 361.

It will be appreciated that, as shown in fig. 7, the engagement surface of the locking block 361 is initially angled with respect to the direction of extension of the first link 341. During the first process, the connecting arm 36 is driven by the driving arm 33 to deflect around the position hinged to the base, so that the locking block 361 can synchronously deflect along with the connecting arm 36; when the first process is completed, the engagement surface of the locking piece 361 is just flush with the extending direction of the first link 341, and at this time, the first link 341 moves just to be in contact with the engagement surface of the locking piece 361, so that the first link 341 can restrict the degree of freedom of the link arm 36 in the return deflection direction. Therefore, in the process that a user operates the handle 2, the handle 2 can be prevented from returning.

In this embodiment, the first connection rod 341 may be correspondingly slidably mounted on the upper base 110, and specifically, the guide block 340 disposed on the first connection rod 341 may be slidably engaged with the guide groove disposed on the upper base 110, the guide groove may only limit the degree of freedom of the first connection rod 341 in the vertical and extending directions, and the horizontal rotation and movement of the first connection rod 341 are not limited; the locking block 361 is correspondingly arranged on the upper part of the connecting arm 36; meanwhile, the end of the first link 341 near the locking block 361 is provided with a slope 3410, and the first link 341 may pass through the cooperation of the slope 3410 and the locking block 361. By the arrangement of the guide block 340 and the inclined surface 3410, the allowable error range of the first link 341 and the locking block 361 during the movement process can be increased, and it is ensured that the locking block 361 does not generate large interference to the movement of the first link 341.

In one embodiment of the present application, as shown in fig. 2, 5, 6, 8, 10 to 18, the unlocking member 37 is rotatably engaged with the base through a first end, and the first end of the unlocking member 37 is further connected with the base through a torsion spring. The unlocking component 37 can be connected with the inhaul cable (not shown) of the door lock mechanism through the second matching portion 373, and the second matching portion 373 deviates from the first end of the unlocking component 37, so that the unlocking component 37 can drive the second matching portion 373 to rotate around the first end synchronously, and then the inhaul cable can be pulled to drive the door lock mechanism to unlock.

Meanwhile, the driving mechanism 3 further comprises a second connecting rod 342 and a connecting part 35, the output end of the actuator 31 can be matched with the unlocking part 37 through the second connecting rod 342, and the extending mechanism can be matched with the unlocking part 37 through the connecting part 35; so that when the second process is performed, the unlocking member 37 can be driven to rotate by the actuator 31 by pushing the second link 342; or the extension mechanism can be pulled by the handle 2 to drive the connecting part 35 to drive the unlocking part 37 to rotate.

It can be understood that, if the extending mechanism is directly connected to the unlocking component 37, the extending mechanism is intended to achieve that the unlocking component 37 is not interfered in the process of extending the driving handle 2, and the design difficulty is high, the structure is complex, and further, the production cost is increased. And set up adapting unit 35 through adding in this application, can reduce the design degree of difficulty, also more conveniently install simultaneously.

In this embodiment, as shown in fig. 13, 15, 16 and 18, the second connecting rod 342 is horizontally slidably mounted on the base; the second link 342 is unlocked by bringing the unlocking member 37 into horizontal rotation. There are various configurations of the second link 342, including but not limited to the following four.

The structure I is as follows: as shown in fig. 5 and 13, one end of the second link 342 is hinged to the unlocking member 37 at a position offset from the first end, and the other end of the second link 342 is initially spaced from the output end of the actuator 31.

Specifically, as shown in fig. 5, 8 and 13, the unlocking member 37 is provided with a first engaging portion 372 at a position offset from the first end, and the second link 342 may be hinged to the first engaging portion 372 at one end. If the first matching part 372 is a hinge rod, the second connecting rod 342 is hinged with the hinge rod through a hinge hole arranged at the end part; if the first engaging portion 372 is a hinge hole, the second connecting rod 342 is hinged by a hinge rod provided at an end portion thereof.

Meanwhile, if the output end of the actuator 31 is provided with the second push rod 322, the corresponding end of the second link 342 is provided with an open slot 3420; if the output end of the actuator 31 is provided with the open slot 3420, the corresponding end of the second link 342 is provided with the second push rod 322.

So that, at the completion of the first process, the output end of the actuator 31 can just cooperate with the unlocking member 37 via the second link 342; in the second process, the second push rod 322 is engaged with the opening groove 3420, so that the unlocking component 37 can rotate around the first end under the continuous driving of the actuator 31, and the door lock mechanism is driven to realize automatic unlocking.

The structure II is as follows: as shown in fig. 5, one end of the second link 342 is hinged to the output end of the actuator 31, and the other end of the second link 342 is spaced apart from the unlocking member 37 at a position offset from the first end.

Specifically, if the output end of the actuator 31 is provided with the second push rod 322, the second connecting rod 342 is hinged to the second push rod 322 through a hinge hole formed at the end; if the output end of the actuator 31 is provided with a hinge hole, the corresponding end of the second connecting rod 342 is hinged to the hinge hole through the second push rod 322.

Meanwhile, the unlocking member 37 is provided with a first engaging portion 372 at a position offset from the first end, and the other end of the second link 342 may be initially spaced apart from the first engaging portion 372. If the first matching portion 372 is a hinged rod, the corresponding end of the second connecting rod 342 is provided with an open slot 3420; if the first fitting portion 372 is the open groove 3420, the corresponding end of the second link 342 is provided with a hinge rod.

So that, at the completion of the first process, the output end of the actuator 31 can just cooperate with the unlocking member 37 via the second link 342; in the second process, the hinge rod and the opening groove 3420 are engaged with each other, so that the unlocking component 37 can rotate around the first end under the continuous driving of the actuator 31, and the door lock mechanism can be driven to realize automatic unlocking.

The structure is three: one end of the second link 342 is hinged to the unlocking member 37 at a position offset from the first end, and the other end of the second link 342 is engaged with the output end of the actuator 31 through a sliding structure.

Specifically, the unlocking member 37 is hinged to the second link 342 through a first engaging portion 372; if the first matching part 372 is a hinge rod, the corresponding end of the second connecting rod 342 is hinged through a hinge hole; if the first engaging portion 372 is a hinge hole, the corresponding end of the second connecting rod 342 is hinged by a hinge rod.

The sliding structure comprises a mutually matched guide groove and a second push rod 322; when the guide groove is provided in the second link 342, the second push rod 322 is provided at the output end of the actuator 31; when the guide slot is provided at the output end of the actuator 31, the second push rod 322 is provided at the second link 342.

Therefore, in the first process, the actuator 31 can realize the sliding of the second push rod 322 relative to one end of the guide groove to the other end by driving the output end, so that the second connecting rod 342 is kept still throughout the first process; in the second process, the actuator 31 drives the output end continuously, so that the second push rod 322 drives the second connecting rod 342 to move through the abutting fit with the guide groove, and the unlocking component 37 rotates to unlock the door lock mechanism.

The structure is four: one end of the second link 342 is hinged to the output end of the actuator 31, and the other end of the second link 342 is engaged with the unlocking member 37 at a position offset from the first end by a sliding structure.

Specifically, if the output end of the actuator 31 is provided with the second push rod 322, the second connecting rod 342 is hinged to the second push rod 322 through a hinge hole provided at the end; if the output end of the actuator 31 is provided with a hinge hole, the corresponding end of the second connecting rod 342 is hinged to the hinge hole through the second push rod 322.

The unlocking member 37 is provided with a first engaging portion 372 at a position offset from the first end; the sliding structure comprises a guide groove and a guide rod which are matched with each other; when the first fitting part 372 is a guide groove, the guide rod is disposed at an end of the second link 342; when the first engaging portion 372 is a guide rod, a guide groove is disposed at an end of the second link 342.

Therefore, in the first process, the actuator 31 can realize the sliding of the guide rod relative to one end of the guide groove to the other end by driving the output end, so that the second connecting rod 342 is kept still throughout the first process; in the second process, the actuator 31 drives the output end continuously, so that the guide rod drives the second connecting rod 342 to move through the abutting fit with the guide groove, and the unlocking component 37 rotates to unlock the door lock mechanism.

It is understood that, as shown in fig. 2, 5, 10 and 12 to 18, in order to ensure a reasonable installation structure of the driving mechanism 3, the unlocking member 37 may be rotatably installed on the lower base 120, so that the second link 342 is correspondingly slidably installed on the lower base 120. Also, in the second process, the movement process of the second link 342 is not linear; therefore, when the guide block 340 disposed on the second link 342 is engaged with the guide groove disposed on the lower base 120, the guide groove only limits the degree of freedom of the second link 342 in the vertical and extending directions, and does not limit the horizontal rotation and movement of the second link 342, so as to ensure that the second link 342 can drive the unlocking member 37 through the combined movement of movement and rotation.

In the present embodiment, as shown in fig. 6 to 8 and 11 to 18, the connecting member 35 is connected to the base by a torsion spring; coupling member 35 includes a coupling plate 351 and a traction plate 352. The connecting plate 351 is rotatably connected to the base by a first end, and the first end of the connecting plate 351 is concentric with the first end of the unlocking member 37. A second end of the connecting plate 351 is connected with a second end of the unlocking member 37 through a driving structure; the connecting plate 351 is hinged with the extending mechanism through a hinge part 350 arranged in the middle; traction plate 352 is attached perpendicularly to attachment plate 351 with traction plate 352 on one side of hinge 350, and traction plate 352 may be coupled to the extension mechanism via a traction structure. When the extension mechanism drives the movement of the handle 2 in a first process, the connection member 35 can be kept stationary by the traction structure; and when carrying out the second process, stretch out the mechanism and receive the pulling of handle 2, can drive connecting plate 351 through pulling the structure and carry out the rotation around first end, and then connecting plate 351 drives unblock part 37 through drive structure and carries out synchronous rotation.

It will be appreciated that by providing the connecting plate 351 to hinge the protracting mechanism and the cooperating unlocking member 37, it is possible to avoid, in the first process, the actuator 31 driving the protracting mechanism from interfering with the unlocking member 37; meanwhile, when manual unlocking is performed in the second process, interference of the rotation of the unlocking member 37 with the actuator 31 can be avoided.

In this embodiment, as shown in fig. 6, 7 and 11, the traction structure includes a traction groove 3520 and a traction block 362 that cooperate with each other. The traction groove 3520 and the traction block 362 are arranged in two ways; first, the traction groove 3520 is disposed on the traction plate 352, and the traction block 362 is disposed on the extension mechanism; in the second mode, the traction groove 3520 is provided on the extension mechanism, and the traction block 362 is provided on the traction plate 352. When the first process that the handle 2 is driven by the extending mechanism to extend out of the door body is carried out, the traction block 362 can slide relative to the traction groove 3520, specifically, the traction block 362 can slide from one side of the traction groove 3520 to the other side; so that the connecting plate 351 remains stationary throughout the first process. When carrying out the second process that manual pulling handle 2 carried out the unblock, whole in-process pull block 362 can remain the counterbalance cooperation with one side of traction groove 3520 all the time to make connecting plate 351 can rotate under the drive of mechanism that stretches out, and then drive unlocking member 37 and rotate unblock lock mechanism in step.

Specifically, for convenience of description, the first mode is adopted for the arrangement of the traction groove 3520 and the traction block 362. As shown in fig. 7 and 10 to 18, one end of the connecting arm 36 away from the handle 2 is hinged to a hinge portion 350 provided on a connecting plate 351; so that the pull block 362 can be located at the side wall of the hinged end of the connecting arm 36. When the manual unlocking is adopted in the second process, as shown in fig. 17 and 18, the handle 2 is pulled, and since the connecting arm 36 does not restrict the handle 2 in the pulling direction, the handle 2 can be turned outwards around the hinge position with the active arm 33; and in the process of handle 2 upset, can pull linking arm 36 and pass through pull block 362 and drive connecting plate 351 and carry out the rotation around articulated position to realize that the synchronous rotation of unblock part 37 unlocks the door lock mechanism.

Meanwhile, the connecting plate 351 and the first end of the unlocking member 37 are both rotatably connected to the lower base 120. The connecting member 35 further includes a support plate 353, one end of the support plate 353 is fixedly connected to one end of the traction plate 352 away from the connecting plate 351, and the support plate 353 is perpendicular to the traction plate 352, i.e., parallel to the connecting plate 351. Thus, a hinge cavity for hinging the connecting arm 36 is formed between the supporting plate 353 and the connecting plate 351, that is, the end of the connecting arm 36 is hinged to the hinge parts 350 arranged on the supporting plate 353 and the connecting plate 351 respectively, so as to improve the connection stability of the connecting arm 36 and the connecting plate 351. Meanwhile, the other end of the support plate 353 is concentric with the first end of the connection plate 351 and rotatably connected to the upper base 110 to improve the connection stability of the entire connection member 35 to the base, and the support plate 353 is connected to the upper base 110 by a torsion spring.

In this embodiment, as shown in fig. 6, 8, and 11 to 18. The driving structure includes an arc-shaped sliding slot 3510 and a sliding block 371, and the center of the sliding slot 3510 is concentric with the first end of the connecting plate 351, that is, the first end of the unlocking member 37. Two arrangement modes of the sliding groove 3510 and the sliding block 371 exist; the method I comprises the following steps: the sliding groove 3510 is provided on the connecting plate 351, and the slider 371 is provided on the unlocking member 37; the second method comprises the following steps: the slide groove 3510 is provided in the unlocking member 37, and the slider 371 is provided in the connecting plate 351. When the unlocking member 37 is automatically unlocked by the actuator 31, the slider 371 can perform relative sliding along the sliding groove 3510 during the rotation of the unlocking member 37, so that the connecting plate 351 is always kept stationary, thereby avoiding interference with the extending mechanism. When the unlocking member 37 is manually unlocked by the handle 2, the slider 371 abuts against one side of the sliding groove 3510, so that the extending mechanism drives the connecting plate 351 to drive the unlocking member 37 to rotate and unlock.

For ease of understanding, the door opening process of the present application will be described in detail in terms of parameters; the structure of the second connecting rod 342 adopts the structure one described above; the traction structure adopts the first mode; the driving structure adopts the first mode.

(1) At the beginning; as shown in fig. 12 and 13, at this time, the handle 2 is retracted into the door body, and the outer side surface of the handle 2 is flush with the outer side of the door body, so that a hidden state is achieved, the door body has good aesthetic property, and wind resistance in the driving process can be reduced.

At this time, the distance between the second push rod 322 disposed at the lower portion of the push block 32 connected to the output end of the actuator 31 and the opening groove 3420 disposed at the end corresponding to the second link 342 is X.

At this time, the pulling block 362 provided at the end of the connecting arm 36 is located at one side of the pulling groove 3520 provided on the pulling plate 352; the slider 371 provided on the unlocking member 37 is located on one side of the slide groove 3510 provided on the connecting plate 351.

(2) Performing a first process; as shown in fig. 14 and 15, the pushing block 32 is driven by the output end of the actuator 31 to move toward the unlocking member 37 by an X distance, so that the second pushing rod 322 on the pushing block 32 is just in contact engagement with the opening groove 3420 provided at the end of the second connecting rod 342.

Meanwhile, in the process that the pushing block 32 moves, the driving portion 320 arranged at the front end of the pushing block 32 can drive the driving arm 33 to rotate around the position hinged to the base through the extrusion fit with the protruding portion 330 on the driving arm 33, so that the four-bar mechanism formed by the driving arm 33, the connecting arm 36, the base and the handle 2 drives the connecting arm 36 and the handle 2 to be linked, and further drives the handle 2 to horizontally extend out towards the outdoor direction in a posture parallel to the door body. And in the process of linkage of the connecting arm 36, the connecting part 35 is limited by the elasticity of the torsion spring to be kept still, so that the connecting arm 36 rotates around the hinge part 350, and can drive the traction block 362 to slide along one side of the traction groove 3520 to be in contact with the other side in the rotating process.

(3) Performing a second process; if automatic unlocking is adopted, as shown in fig. 16; the push block 32 can move for a distance Y again under the continuous driving of the output end of the actuator 31; therefore, the second link 342 can move synchronously by the distance Y, and during the movement of the second link 342, the unlocking member 37 can be driven to rotate around the first end to unlock the door lock mechanism by being engaged with the first engaging portion 372, which is offset from the first end, on the unlocking member 37, and during the rotation of the unlocking member 37, the slider 371, which is arranged on the unlocking member 37, can slide along the sliding groove 3510, so that the connecting member 35 can be kept stationary during the automatic unlocking process under the elastic force of the torsion spring, and the torsion spring, which is connected with the unlocking member 37, is in a compressed state.

If manual unlocking is adopted, as shown in fig. 17 and 18; when the handle 2 is pulled, the handle 2 can deflect around the hinge position of the active arm 33, and during the deflection, the connecting arm 36 can be matched with the side part of the traction groove 3520 through the support of the traction block 362, so as to drive the connecting component 35 to rotate around the hinge position of the first end. In the process of rotating the connecting member 35, the torsion spring connected with the connecting member is in a compressed state, and the side portion of the sliding groove 3510 on the connecting plate 351 is in abutting fit with the upper sliding block 371 on the unlocking member 37, so that the unlocking member 37 can be driven to synchronously rotate around the first end to unlock the door lock mechanism, and in the process of rotating the unlocking member 37, the torsion spring connected with the unlocking member is also in a compressed state.

(4) The handle 2 is reset after the vehicle door is opened; if the second process adopts automatic unlocking; the actuator 31 drives the pushing block 32 to move back by the distance X + Y to the initial position. In the process of resetting the push block 32, the active arm 33 drives the handle 2 to perform reverse horizontal movement through the four-bar mechanism under the resetting elasticity of the torsion spring until the handle is contracted into the door body. Meanwhile, the unlocking member 37 is also reversely rotated by the return elastic force of the torsion spring up to the initial position after being adapted to the pressing of the push block 32.

If the second process adopts manual unlocking; then the handle 2 is loosened, the connecting part 35 can drive the handle 2 to reset to the welcome state in the first process under the reset elasticity of the torsion spring; the unlocking member 37 is also rotated reversely to the initial position by the return elastic force of the torsion spring in this process. Then the actuator 31 drives the push block 32 to move back by a distance X to an initial position, and in the process, the active arm 33 drives the handle 2 to perform reverse horizontal movement through the four-bar mechanism under the reset elasticity of the torsion spring until the handle is retracted into the door body.
