Description

CROSS-REFERENCE TO RELATED REGISTRATIONS

[0001] This application is the entry into the national phase of international patent application No. PCT / KR2023 / 012888, filed on 30 August 2023, and claims the benefits of Korean patent application No. 10-2023-0064687, filed on 19 May 2023, the disclosures of which are incorporated in full into this document by reference. field of technology

[0002] The present disclosure relates to a flush handle for a vehicle door which is capable of opening a door while, when pulling on an extendable handle unit, a locking bar is pressed down by lowering an opening bar. General state of the art

[0003] A flush handle for a vehicle door is a handle that opens a door by pulling on an open cable 30, which is a door lock connector, and releasing a lock when a user pulls on a handle unit referred to as a knob after the handle unit has been pulled out from a retracted state (safety cable operation).

[0004] An example of the conventional flush handle for a vehicle door described above is disclosed in the patent specification (Korean patent no. 10-2144784).

[0005] In a flush handle for a vehicle door, disclosed in the patent specification, the open cable 30 is pulled to open the closure of a latch, while a lever 4950 rotates by pulling on a handle unit (see Fig. 34), which is pulled out from an initial position of the handle unit (see Fig. 33).

[0006] The open cable 30 itself requires a large number of manufacturing processes and components.

[0007] The flush handle for a vehicle door, disclosed in the patent specification, detects the position of the handle unit by pressing a switch 23b, which corresponds to the initial position (see Fig. 35) corresponds to the handle unit, or pressing a switch 23a which corresponds to an extended position (see Fig. 36) the handle unit corresponds to, depending on a movement of a moving nut 4750.

[0008] Switches 23a and 23b can be provided as separate components with an installation groove in a housing or take up a lot of space, resulting in an increase in size (since the switches have to be installed inside a vehicle door panel, compactness is very important).

[0009] Furthermore, switches 23a and 23b are connected by wires, and therefore the wiring to the outside may be exposed and may be complicated.

[0010] Since the moving nut 4750 pulls a slide 4600 into a state where a leadscrew 4727 and the moving nut 4750 are located outside a driver 4700, this may be difficult to assemble and operate, and may cause resonance noise from the slide 4600. Furthermore, the structures of the slide 4600 and the driver 4700 are distributed, which makes modularization difficult. State of the art document Patent specification

[0011] (Patent specification 1) Korean Patent No. 10-2144784 Disclosure of the invention Technical problem

[0012] One purpose of the present revelation is to address the problems described above and others.

[0013] Another objective of the present disclosure is to provide a flush handle for a vehicle door which is very advantageous in terms of reducing costs by pressing on a locking bar to open a door, while a single bar lowers when a retractable handle unit is pulled.

[0014] Another objective of the present disclosure is to provide a flush handle for a vehicle door which is highly advantageous in terms of compactness, durability and economy due to a structure for detecting an electrical contact, without using a separate switch component for detecting a start position and an extension position of a handle unit.

[0015] Another objective of the present disclosure is to provide a flush handle for a vehicle door that is easy to assemble and operate by pulling directly on a slider through a leadscrew and a structure acting as a nut, which are placed inside a driver to allow modularization of the driver, and is advantageous with respect to noise by eliminating resonance of the slider. Solution to the problem

[0016] To solve the problems described above and others, one aspect of the present disclosure provides a flush handle for a vehicle door, comprising, where a longitudinal direction of a vehicle is an x-direction, a width direction of the vehicle is a y-direction, and a height direction of the vehicle is a z-direction, a housing penetrating in the y-direction; a slider slidably arranged within the housing; a handle unit slidably arranged within the slider; a linear motion conversion unit configured to support relative movement of the slider in the x-direction and movement of the handle unit in the y-direction; a slider driver mounted within one side of the housing and configured to pull on the slider; and a rod.and a rod drive mechanism configured to push on and open a door lock while the rod moves downward in the z-direction when the extended handle unit is pulled in the y-direction. Advantageous effects of the invention

[0017] The effects of a flush handle for a vehicle door according to the present disclosure are described below.

[0018] According to at least one embodiment of the present disclosure, it can be advantageous in terms of cost reduction compared to cables by pressing on a locking bar using a rod to open a door.

[0019] According to at least one embodiment of the present disclosure, there is little wear due to friction, since an electrical contact takes the form of an inclined lever and only exerts pressure and energizes in a starting position or an extension position, which can be advantageous with regard to durability.

[0020] According to at least one embodiment of the present disclosure, no separate switch is required, since a structure for detecting an electrical contact is used with the aid of cables and connectors, which is advantageous in terms of cost and does not take up much space, thus contributing to compactness.

[0021] According to at least one embodiment of the present disclosure, since a leadscrew unit adopts a structure that pulls directly on a slide, the role of the slide and a driver becomes more defined, modularization is possible, making assembly and operation simple, and eliminating slide resonance, which can be advantageous with regard to noise.

The return spring 480 can be stably installed between a right seat 481 and a left seat 482. The return spring 480 can include a compression spring.

[0061] Regarding the Fig. 7, Fig. 14 and Fig. 21. The slide driver 420 can include the unit 490 for detecting an electrical contact. The unit 490 for detecting an electrical contact can detect a start position or an extension position of the handle unit 300.

[0062] The unit 490 for detecting an electrical contact can include an initial position tilting lever 491. As in Fig. As illustrated in Figure 14, a right side 491a of the initial position lever 491 can be fixed to the second housing 120, and a left side 491b of the initial position lever 491 can be suspended, so that a gap h1 is formed between the left side 491b and the second housing 120. The left side 491b of the initial position lever 491 can include an upwardly convex arcuate pressed piece 491b' and a foot 491b''. The foot 491b'' can have a plate shape extending horizontally towards the outside of the pressed piece 491b'. The foot 491b'' can be energized / de-energized by attaching it to and detaching it from an initial position terminal 493.

[0063] The unit 490 for detecting an electrical contact can include an extension position lever 492. As in Fig. As illustrated in Figure 7, a left side 492a of the extension position lever 492 can be fixed to the second housing 120, and a right side 492b of the extension position lever 492 can be suspended, forming a gap h2 between the right side 492b and the second housing 120. The gap h2 can be essentially the same as the gap h1. The right side 492b of the extension position lever 492 can include an upwardly convex arcuate pressed piece 492b' and a foot 492b''. The foot 492b'' can have a plate shape extending horizontally towards the outside of the pressed piece 492b'. The foot 492b'' can be energized / de-energized by attaching it to and detaching it from an extension position terminal 494.

[0064] The electrical contact detection unit 490 can include the initial position terminal 493 and the extension position terminal 494 of a wire 496, which is wired inside the second housing 120. The initial position terminal 493 and the extension position terminal 494 are connected via the wire 496 to a connector 495. The connector 495 can be installed outside one side of the second housing 120.

[0065] Accordingly, if the press protrusion 455c is on the left side, as in Fig. Figure 7 illustrates that when the left side 491b of the initial position lever 491 is pressed, it contacts the initial position terminal 493, thereby energizing it. Conversely, when the right side 492b of the extension position lever 492 is not pressed, a lack of power is detected.

[0066] If the press protrusion 455c is on the right side, as in the Fig. 14 and Fig. As illustrated in Figure 21, pressure is applied to the right side 492b of the extension position lever 492, causing it to contact the extension position terminal 494 and thus energize it. Conversely, no pressure is applied to the left side 491b of the initial position lever 491, and a lack of energization is detected.

[0067] When, as above, the press projection 455c moves to the left and right, pressure is applied only to floating sections such as the left side 491b of the initial position swash lever 491 and the right side 492b of the extension position swash lever 492, thus preventing power loss and a reduction in the detection rate by eliminating a phenomenon in which parts rub against each other due to continuous friction.

[0068] The initial position swashplate lever 491 and the extension position swashplate lever 492 can detect the initial position and the extension position of the handle unit 300 by electrical current by arranging a brass plate connection depending on the position.

[0069] The initial position swashplate lever 491 and the extension position swashplate lever 492 can form a pair. < Rod drive mechanism 500 >

[0070] When the rod drive mechanism 500 extends the handle unit 300, as in the Fig. 8 and Fig. 9 illustrates, pulls forward, as in the Fig. 15 and Fig. Figure 16 illustrates that while the rod R moves downwards, the door lock (not shown) can be pushed down and opened, as shown in Fig. 18 illustrated.

[0071] Since the rod R is a steel rod and is operated as a single steel rod, it can be very advantageous in terms of cost reduction compared to the conventional open cable 30 and the design can be simpler and cleaner than the open cable 30.

[0072] Regarding the Fig. 22 and Fig. 25 The rod drive mechanism 500 can include a bracket 510. The bracket 510 can be formed on a lower surface of the first housing body 111.

As shown in the Fig. 26 and Fig. As illustrated in Figure 27, a covering 1541a can be fitted to the inclined piece 1541. The covering 1541a is made of a plastic material and can minimize wear resulting from relative movement to the upper side 527 of the pivot lever 520.

[0079] The rod drive piece 1540 can include a support piece 1543. The support piece 1543 can be installed in the first housing 110 so that it is movable in the forward-backward direction. The support piece 1544 can include a vertical support piece 1543, which supports the inclined piece 1541 at its lower end. (Referring to) Fig. 22 A lower side of the vertical support piece 1544 can be slidably arranged in a cutout groove 1544a formed in the lower plate of the first housing 110. The support piece 1543 can include a horizontal support piece 1545. The horizontal support piece 1545 can project forward from an upper end of the vertical support piece 1544. The horizontal support piece 1545 can be arranged in a guide groove 1545a formed in the forward-backward direction on an inner wall of the upper plate of the first housing 110. The guide groove 1545a can be arranged parallel to the first and second guide grooves 405 and 406.

[0080] The rod drive piece 1540 can include a slotted hole piece 1546. The slotted hole piece 1546 can include an extension piece 1547, which extends forward between the horizontal support piece 1545 and the inclined piece 1541, and a slotted hole 1548 formed in the extension piece 1547 in a horizontal direction. The slotted hole piece 1546 can have a length that projects further forward than the horizontal support piece 1545.

[0081] Regarding the Fig. 28, Fig. 29, Fig. 30 to Fig. The rod driver 540 can include a push unit 2540. The push unit 2540 can be arranged within one side of the first handle unit 310 so that it is movable in one direction of pull.

[0082] The push unit 2540 can include a push rod 2541. The push rod 2541 can be slidably arranged on one side of the first handle unit 310. A pin hole 2542 can be formed in front of the push rod 2541. As in Fig. As illustrated in Figure 29, pins 325 can be installed in a pin groove 333 and a pin hole 2542 formed on the front surface of the second handle frame 331 and can be pulled together on the second handle unit 330 and the push unit 2540.

[0083] Regarding Fig. 13. The push unit 2540 can include a slotted groove 2543. The slotted groove 2543 can be formed within the push rod 2541 in the direction of the front from a rear surface of the push rod 2541. The slotted piece 1546 can be slidably inserted into the slotted groove 2543.

[0084] The 540 rod driver can include a 3540 pull-stop piece.

The drawbar locking piece 3450 can include a horizontal pin 3451. The drawbar locking piece 3450 can include horizontal pin holes 3453 formed on the left and right sides of the push rod 2541. Therefore, the horizontal pin 3451 can be arranged through the horizontal pin hole 3453 in the slotted hole 1548 of the slotted hole piece 1546.

[0085] Regarding the Fig. 6 and Fig. 28. The rod driver 540 can include a compression helical spring 4540. When the pull is released, the compression helical spring 4540 can reset the pulled push unit 2540 relative to the first handle unit 310.

[0086] The rod drive mechanism 500 can include a rod non-driver 550. When an impact is exerted on the vehicle door, the rod non-driver 550 can prevent the pivot lever 520 from lowering as a result of the impact. That is, the rod non-driver 550 can prevent the pivot lever 520 from lowering when a counterweight element 1550 is deployed. Fig. 26 enters a distance c between the first support 511 and the second support 512 (see Fig. 27).

[0087] Regarding Fig.The rod non-driver 550 can include the counterweight element 1550. The counterweight element 1550 can include a weight 1551 that shifts the center of gravity to one side. The counterweight element 1550 can include a pivot hole 1552 that penetrates both upwards and downwards. The pivot hole 1552 can be rotatably mounted on a support shaft 1553 formed on a lower face of the pivot lever 520. The counterweight element 1550 cannot fall downwards due to a C-ring 1554 that is assembled with the support shaft 1553. In addition, a guide rib 1555 can project downwards from the lower face of the pivot lever 520. The guide rib 1555 can act as a guide so that it does not move up and down when the counterweight element 1550 rotates.

[0088] The rod non-driver 550 can include a torsion coil spring 2550. The torsion coil spring 2550 can be installed between the lower surface of the pivot lever 520 and an upper surface of the counterweight 1550. The torsion coil spring 2550 can exert an outward (rearward) spring force on the counterweight 1550 relative to the pivot lever 520. Therefore, the torsion coil spring 2550 does not normally interfere with the operation of the pivot lever 520, and the counterweight 1550 does not prevent the pivot lever 520 from lowering.
