It is preferable to rotate and tilt and pop up. At this time, the tilting pop-up means that one side of the grip body 421 is rotated and inserted into the door case part 410 based on the grip rotation shaft 420a, and the other side of the grip body 421 is the It means that it is rotated and popped up from the door case part 410.

In addition, the grip body 421 is a multi-stage rotation type, that is, when the smart key (not shown) is approached in a state inserted into the receiving space 411, it is automatically rotated first and then pulled by the user to rotate the second time. It is preferable to be provided in a way that is. In detail, the grip body 421 is first rotated when the extension body 422 formed integrally with the grip body 421 by the extension driving part 430 is pressed and tilted and pops up from the accommodation space 411 , In a state in which the tilting pop-up is first rotated, as the door case unit 410 is pulled outward by the user, it may be rotated secondarily. At this time, it is preferable to understand that the angle of the grip body 421 at the time of the second rotation relative to the outer surface of the door 1 is greater than the angle at the time of the first rotation. For example, when the angle at the time of the first rotation is 19.5deg, the angle at the time of the second rotation may be set to 27.5deg.

On the other hand, the extension body 422 is preferably formed to extend integrally in the inner direction of the door case portion 410 from the inner end of the grip body 421. In addition, the extension body 422 is disposed substantially perpendicular to the grip body 421 and is preferably provided in a flat plate shape such as a rectangular parallelepiped. At this time, substantially vertical means when the extension body 422 is disposed inclined at a fine predetermined angle close to perpendicular to the grip body 421, and the interface between the grip body 421 and the extension body 422 It is desirable to understand that the case is formed in a round shape as well.

Here, it is preferable that the extension body 422 integrally protrudes from a position corresponding to the end of the extension rod portion 430 in the inner direction of the door case portion 410. That is, it is preferable that the grip part 420 is provided in an eccentric "T" shape.

In addition, the extension body 422 is preferably formed at a position eccentric in the direction of one side of the grip body 421 from the central portion of the grip body 421. In detail, it is preferable that one end side of the extension body 422 is disposed at a position that selectively contacts the end of the extension rod part 432 of the extension drive part 430. At this time, when the extension rod part 432 is contracted by the actuator 431 of the extension driving part 430, the extension body 422 and the extension rod part 432 are spaced apart from each other, and the extension rod part ( When 432 is extended by the actuator 431 of the extension driving part 430, it is preferable that the extension rod part 432 presses the extension body 422.

And, the distance from the outer end of the extension body 422 to one end of the grip body 421 is formed to be less than the distance from the outer end of the extension body 422 to the other end of the grip body 421 This is desirable. At this time, it is preferable to understand that the extension driving part 430 is disposed on one side of the grip body 421. Through this, when the grip body 421 is tilted and popped up, the area into which the grip body 421 is rotated and inserted into the receiving space 411 is minimized, so that a product can be miniaturized and space utilization can be improved.

Here, when the extension rod part 430 presses the extension body 422, one side of the grip body 421 is rotated and inserted into the accommodation space 411 with respect to the grip rotation shaft 420a, It is preferable that the other side of the grip body 421 first rotates in an outward direction of the door case portion 410 to be tilted and popped up.

In addition, a contact expansion protrusion may be formed at an inner end of the extension body 422 to be bent to extend toward an arrangement direction of the extension driving part 430 and an arrangement direction of the latch part 460, respectively.

On the other hand, the extension driving part 430 is disposed on one side of the door case part 410 or one side of the door, so that the grip body 421 is rotated firstly so as to be tilted and expanded from the receiving space 411. According to It is preferable to selectively press the extension body 422.

Here, the extension driving part 430 is provided on one side of the door case part 410 or one side of the door 1 and is driven to tilt and pop the grip body 421, and the actuator It is preferable to include an extension rod part 432 which is connected to 431 and selectively expands and contracts to selectively press the extension body 422.

In detail, the actuator 431 may be provided in a hollow cylindrical shape or the like, and one side in the length direction may be opened. In addition, it is preferable that one side of the actuator 431 is disposed toward the extension body 422.

In addition, the extension rod part 432 may be provided in a cylindrical shape corresponding to the shape of the actuator 431, and the outer diameter of the extension rod part 432 substantially corresponds to the inner diameter of the actuator 431 It can be formed to be.

In addition, the extension rod part 432 has one end inserted and disposed inside the actuator 431, and the other end is disposed in a state exposed from the actuator 431, so that the extension body is extended by the actuator 431. It is preferable to selectively pressurize (422). In addition, the extension rod part 422 is selectively expanded and contracted in response to the drive of the actuator 431, and is preferably disposed along the front and rear directions of the door case part 410.

For example, when the length of the door case portion 410 in the front and rear direction is 340 mm, the reciprocating range of the extension rod portion 432 may be set to 7.5 mm. At this time, when the extension rod portion 432 is extended by 7.5mm from the actuator 431, the extension rod portion 432 presses the extension body 422, and the extension body 422 is the grip rotation shaft ( Based on 420a), it can be rotated 19.5deg.

Accordingly, by driving of the actuator 431, the extension rod part 432 may be expanded and contracted from the actuator 431 in either a forward direction or a reverse direction. Here, as long as the extension rod part 432 is selectively expanded and contracted by the actuator 431, it is not limited thereto.

Through this, when a control signal is received by the actuator 431 through the controller 470 and the approach detection sensor 471 to be described later, the actuator 431 is configured to expand and contract the extension rod part 432. Since the expansion rod part 432 is automatically controlled, the operating precision can be remarkably improved.

In addition, the extension body 422 formed integrally with the grip body 421 is formed at an eccentric position in the direction of one side of the grip body 421 from the central portion of the grip body 421 so that the actuator 431 Since the pressing force is amplified by the lever principle, energy efficiency can be improved. Moreover, since the rotation distance of the extension body 422 is minimized, the product can be miniaturized.

On the other hand, it is preferable that the retractable door handle 500 further includes an approach detection sensor 471 that detects an approach when a smart key (not shown) of a separately provided vehicle approaches within a preset distance from the vehicle.

Here, the access detection sensor 471 may be provided as a Light Detection And Ranging (LIDAR) sensor, a Radio Frequency Identification (RFID), or the like, and may be provided to be embedded in the grip part 420. At this time, the approach detection sensor 471 may be installed in the side mirror and the front and rear of the vehicle when installed in the vehicle, and in some cases, it may be installed inside the door 1 or the door case part 410 have.

Accordingly, when a user holding a smart key (not shown) approaches the access detection sensor 471 within a preset radius distance, the access detection sensor 471 may detect the approach of the smart key (not shown). I can.

In addition, the retractable door handle 500 is the extension driving unit so that the grip body 421 tilts and pops up from the accommodation space 411 when the access detection sensor 471 detects the smart key (not shown). It is preferable to include the control unit 470 for controlling 430. In detail, the control unit 470 controls the actuator 431 so that the grip body 421 tilts and pops up from the accommodation space 411 when the proximity sensor 471 detects the smart key (not shown). It is desirable to transmit a signal.

Here, it is preferable that the actuator 431 is selectively controlled to be driven in the forward and reverse directions, and as the actuator 431 is driven and controlled, the extension rod part 432 interlocked therewith is the extension rod part 432. It can be expanded and contracted in the forward and reverse directions with respect to the longitudinal axis. At this time, the forward direction means a case where the extension rod part 431 is extended from the actuator 431, and the reverse direction means a case where the extension rod part 431 is contracted to the actuator 431 It is desirable to understand it. In addition, the above-described forward and reverse directions are preferably understood as an example described in an embodiment of the present invention, and the configuration in which the forward and reverse directions of the above-described extension driving unit 430 are switched to each other is also understood as being included in the scope of the present invention. This is desirable.

In detail, referring to FIG. 3, the control unit 470 allows the grip unit 420 to be completely inserted into the accommodation space 411 when the door case unit 410 moves, that is, when the vehicle is driven and when the vehicle is turned off. It is preferable that the extension driving unit 430 is controlled to drive in the reverse direction for a preset time. Here, when the extension drive part 430 is driven in the reverse direction, the extension rod part 432 interlocked with the actuator 431 is contracted to release the pressure of the extension body 422, so that the grip body 421 It can be completely inserted into the accommodation space (411).

In this case, the elastic member (not shown) may be provided for elastically restoring the grip body 421 so that it is completely inserted into the receiving space 411. In addition, a separate sensor (not shown) for detecting movement of the vehicle or the door case unit 410 and power off of the vehicle may be further provided. Through this, when a signal for movement of the vehicle or the door case unit 410 and power off of the vehicle is transmitted to the control unit 470, the extension driving unit 430 can be controlled to be driven in the reverse direction for a preset time. have.

Accordingly, when the door case portion 410 is moved, that is, when the vehicle is driven and when the vehicle is powered off, the grip body 421 is completely inserted into the accommodation space 411, thereby preventing wind noise caused by the wind. Internal noise is reduced, and driving performance of the vehicle may be improved by improving airflow.

In addition, referring to FIG. 4, the control unit 470 is the grip body 421 when the approach detection sensor 471 detects the smart key (not shown) and when the door 1 is opened or the vehicle is stopped. It is preferable to control the extension driving unit 430 in the forward direction for a preset time so that) is first rotated from the accommodation space 411 by a preset length and tilted to pop up. Here, when the extension driving part 430 is driven in the forward direction, the extension rod part 432 interlocked with the actuator 431 is rotated in the forward direction to press the extension body 422 so that the grip body 421 receives the It may be rotated first from the space 411 and tilted and popped up.

Here, when the access detection sensor 471 detects the smart key (not shown), a detection signal may be transmitted from the access detection sensor 471 to the control unit 470. Through this, as the smart key (not shown) approaches within a preset radius range of the access detection sensor 471, the extension driving unit 430 may be controlled to be driven in a forward direction for a preset time.

Therefore, the grip body 421 inserted into the receiving space 411 through the mutual configuration of the extension driving unit 430, the control unit 470, and the access detection sensor 471 requires a tilting pop-up. In this case, since it is selectively popped up from the receiving space 411 through the opening 413, the usability can be remarkably improved.

Accordingly, as the actuator 431 is electrically controlled when the smart key (not shown) approaches by the approach detection sensor 471, the grip body 421 provided in a multi-stage rotation type is provided in the receiving space ( When the grip body 421, which is first rotated and popped up from 411, is first rotated and popped up, is pulled outward of the door case part 410 by a user, it is rotated secondarily and a door locking device (not shown) ) Is unlocked, and the convenience of use and operation precision can be improved.

Here, when the grip body 421 is first rotated from the accommodation space 411 and tilted pop-up, it is understood that the locked state of the door locking device (not shown) provided in the door case part 410 is maintained and tilted pop-up. This is desirable. That is, when the grip body 421 is first rotated from the receiving space 411 by the extension driving part 430 and pops up, the inner end of the extension body 422 is latched by the latch part 460 It is preferable to understand that the state in which the firing portion 461 is not pressed is maintained.

Accordingly, the lower portion of the extension body 422 does not press the latch seesaw portion 461 of the latch portion 460 regardless of whether the grip body 421 is popped up and inserted from the receiving space 411 Therefore, the door locking device (not shown) is not opened. That is, the door locking device (not shown) for opening and closing the door case unit 410 is not opened regardless of the tilting pop-up and insertion of the grip body 421 by the extension driving unit 430. Therefore, there is a difference from the configuration in which the door is unlocked when the contact sensor is provided on the inner surface of the accommodation space, and the door is locked when the contact sensor comes into contact with the contact part provided on the inside of the handle. It is desirable to understand.

Through this, the grip body 421 is first rotated from the accommodation space 411 to maintain a locked state of the door locking device (not shown) when tilting pop-up, and tilting pop-up can be performed. Accordingly, even if the grip body 421 is unintentionally tilted and popped up from the accommodation space 411 due to aging, external force action, or malfunction of the device, automatic release of the door locking device (not shown) can be prevented in advance. have.

Accordingly, the door locking device (not shown) is kept in a locked state regardless of whether the tilting pop-up and the tilting pop-up of the grip body 421 inserted selectively by the extension driving unit 430 are maintained, so that the door locking is not intended. The automatic release of the device (not shown) is prevented in advance, so that safety in use can be remarkably improved.

Meanwhile, referring to FIGS. 3 to 6, the latch part 460 is rotated first and the grip body 421 in a tilted pop-up state is pulled outwardly of the door case part 410. When the door locking device (not shown) is preferably provided to mediate the transmission of the operating force by the operation of the end of the extension body 422 to open and close.

In addition, the latch part 460 is held and pressed by the extension body 422 when the grip body 421 in a state in which one side 461a is first rotated and tilted and popped up, is pressed and pressed by the extension body 422 and a first latch It is preferable to include a latch seesaw part 461 provided so that the rotation shaft 461b rotates by a hinge. Here, the latch seesaw part 462 may be provided in a bar shape, and one side may be disposed at a position that selectively contacts the end of the extension body 422 and the other side may be disposed toward the latch through hole 414.

In addition, the first latch rotation shaft 461b hinged to the door case part 410 is provided at the central part of the latch seesaw part 462, and the first latch rotation shaft 461b is the latch seesaw part It is preferable to be eccentrically arranged in one direction of the latch seesaw part 461 from the central part of 461.

Here, the distance d1 between the first latch rotation shaft 461b and the one side 461a of the latch seesaw part 461 is the other side of the latch seesaw part 461 from the first latch rotation shaft 461b. It is preferably set to be less than the distance d2 between (461c).

In addition, it is preferable that one side 461a of the latch seesaw part 461 is disposed at a position in which an end portion of the extension body 422 can be selectively contacted. In detail, one side 461a of the latch seesaw part 461 is not pressed against the extended body 422 integrally rotated when the grip body 421 is rotated first and tilted pop-up, but is in contact with or disposed adjacent to each other. It is preferred to be placed in position. Here, the grip body 421 in a state in which the first rotation is tilted and popped up is pulled by the user and the extension body 422 formed integrally with the grip body 421 is interlocked and rotated when the grip body 421 is rotated. It is preferable to press the one side 461a of the firing portion 461.

For example, the latch seesaw part pressed by the extension body 422 when the grip body 421 is first rotated by the user by 8deg in the outward direction of the door case part 10 ( The other side 461c of the latch seesaw part 461 may be rotated from one side of the latch through hole 414 to the other side by rotating 461 by 19deg with respect to the first latch pivot shaft 461b. That is, the ratio between the rotation angle of the grip body 421 in the second rotation of the grip body 421 in the state of the first rotation and tilting pop-up and the rotation angle of the latch seesaw part 461 may be set to 1:2.0 to 2.5.

Therefore, the first latch rotation shaft 461b of the latch seesaw part 461 is eccentrically disposed from the center of the latch seesaw part 461 to one side in which the extension body 422 is disposed, so that the user is first rotated. When the grip body 421 in a tilted popped state is pulled, an external force is amplified by a lever principle, so that energy efficiency can be improved. In addition, since the rotation distance of the extension body 422 is minimized, the product can be miniaturized.

At this time, in some cases, the extension body 422 has a first cloud contact part formed on a contact surface with one side 461a of the latch seesaw part 461, and the first cloud contact part is formed on one side 461a of the latch seesaw part 461 A second cloud contact portion may be formed in rolling contact with the first cloud contact portion to minimize frictional force. In this case, the first cloud contact portion and the second cloud contact portion may be formed as toothed gears, but are not limited thereto.

Through this, the grip body 421 in a state in which the tilting pop-up state is first rotated is rotated secondarily as the user pulls it, so that the extension body 422 presses one side 461a of the latch seesaw part 461 The wear is substantially prevented by minimizing the frictional force between the times, so the durability of the product can be remarkably improved.

In addition, the other side 461c of the latch seesaw part 461 is preferably connected to the latch connection shaft 463 disposed to pass through the latch through hole 414.

Meanwhile, referring to FIG. 6, the latch part 460 is disposed outside, that is, upper or lower, of the door case part 410, but one side 462a is on the other side 461c of the latch seesaw part 461. It is connected through the latch connection shaft 463 and includes a latch cable holder 462 to which a second latch rotation shaft 462b is provided to rotate by a hinge, and a wire w for providing a tensile force to the other side 462c is connected.

At this time, one side 462a of the latch cable holder 462 and the other side 461c of the latch seesaw part 461 are connected to each other through the latch connection shaft 463 to rotate along the latch through hole 414 It is preferable that each of the latch through holes 414 are aligned and arranged.

Here, as the grip body 421 in the first rotation and tilting pop-up state is pulled by the user, the grip body 421 is rotated secondarily, and the extension body 422 presses one side 461a of the latch seesaw part 461 This is desirable. Accordingly, the latch connection shaft 463, the other side 461c of the latch seesaw part 461, and one side 462a of the latch cable holder 462 from one side of the latch through hole 414 to the other side It is desirable to rotate. Subsequently, when one side 462a of the latch cable holder 462 is rotated with respect to the second latch rotation shaft 462b, the other side 462c of the latch cable holder 462 rotates interlockingly, so that the wire w ) Is preferably pulled. In addition, as the wire w is pulled, the door locking device (not shown) is released in a locked state, so that the door 1 may be opened.

For example, the latch seesaw part 461 pressed by the extension body 422 is rotated by 19deg with respect to the first latch rotation shaft 461b so that the other side 461c of the latch seesaw part 461 is It may be rotated from one side of the latch through hole 414 to the other side. Subsequently, one side 462a of the latch cable holder 462 is rotated by 56deg with respect to the second latch pivot shaft 462b, and the wire w may be pulled. That is, the rotation angle of the latch cable holder 462 that finally pulls the wire w by pulling the grip body 421 by 8deg by the user may be amplified by 56deg, that is, 7 times.

Accordingly, even if the user pulls the grip body 421 at a minimum rotation angle, the door 1 can be easily opened as the door locking device (not shown) is amplified to a rotation angle for unlocking. The usability can be remarkably improved.

Therefore, when the grip body 421 in the first rotation and tilted pop-up state is pressed in the outward direction of the door case portion 410, the door locking device (not shown) is unlocked, so that the usability can be improved. . In some cases, after the door locking device (not shown) is unlocked, the latch unit 460 is elastically restored to rotate in the reverse direction, so that the latch unit 460 provides a separate elastic restoration unit (not shown). It may include more.

In addition, the door locking device (not shown) is preferably provided to be connected to the latch unit 460 to selectively open and close the door 1 by an operating force generated by the extension body 422.

On the other hand, referring to FIGS. 3 to 5 and 7, the retractable door handle 500 is provided inside the door case part 410 to provide an emergency opening means for mediating the opening of the door 1 ( It is preferable to further include 480). At this time, the emergency opening means 480 is an emergency situation, that is, when the kidney driver 430 is not operated due to a cause such as an accident, a discharge of a vehicle battery, a circuit disconnection, or the grip unit ( It means a device that is manually driven when 430) is not operated.

Here, the emergency opening means 480 includes an emergency switch unit 481 disposed inside the door case unit 410 and provided such that a contact surface is selectively pressed by the inside of the grip body 421 desirable.

In detail, the emergency switch unit 481 includes a switching rod having an outer end spaced apart from the inner end of the drawing body 421 by a minute distance, and the control unit 481 provided at an inner end of the switching rod when the switching rod is pressed. It may include a contact sensor for transmitting a contact signal to 470, and an elastic spring provided to surround the outer surface of the switching rod.

Here, the emergency switch part 481 may be disposed in the receiving space 411 inside the door case part 410 corresponding to the other side of the grip body 421. Accordingly, when the grip body 421 is not tilted and popped up due to an external environment or device failure, when the user touches and presses the other side of the grip body 421, the grip body 421 becomes the door case. The emergency switch unit 481 may be pressed as the unit 410 is rotated and inserted finely into the inner side of the unit 410.

In addition, when the emergency switch unit 481 is pressed, it is preferable that the control unit 470 controls the actuator 431 of the extension driving unit 430 in the forward direction as a contact signal is transmitted to the control unit 470. That is, when the user touches and presses the other side of the grip body 421, the emergency switch 481 senses this and the actuator 431 is controlled in the forward direction, so that the grip body 421 first rotates and tilts to pop up. I can.

In addition, it is preferable that the emergency opening means 480 includes a key holder 482 disposed inside the door case portion 410 to selectively insert a key for opening the door 1.
