Description

TECHNICAL FIELD

[0001] The present disclosure relates to a flush handle of a vehicle door that can open the door while lowering an opening lever to push a latch lever upon pulling out a handle unit. BACKGROUND

[0002] The flush handle of a vehicle door is a handle that opens a door by pulling an open cable 30 that is a door latch connector and releasing a latch upon a user pulling a handle unit after the handle unit, which is called a knob, is pulled out from a retracted state (safe cable operation).

[0003] An example of the above-described conventional flush handle of a vehicle door is disclosed in a patent document (Korean Patent No. 10-2144784).

[0004] In the flush handle of a vehicle door disclosed in the patent document, when a lever 4950 is rotated upon pulling a handle unit (see FIG. 33 ) that is pulled out from an initial position (see FIG. 34 ) of the handle unit, an open cable 30 is pulled to open the closure of a latch.

[0005] The open cable 30 itself requires a large number of manufacturing processes and parts.

[0006] The flush handle of a vehicle door disclosed in the patent document detects the position of the handle unit by pressing a switch 23b corresponding to the initial position (see FIG. 35 ) of the handle unit or pressing a switch 23a corresponding to the pull-out position (see FIG. 36 ) of the handle unit according to the movement of a moving nut 4750.

[0007] The switches 23a and 23b, which are separate components, can have a mounting groove in the housing or occupy a large amount of space, thereby causing an increase in size (since the switches must be mounted in the door panel, compactness is very important).

[0008] In addition, the switches 23a and 23b are connected to a wire, and thus wiring can be exposed to the outside and can be complex.

[0009] Since the moving nut 4750 pulls the slider 4600 in a state in which the lead screw 4727 and the moving nut 4750 are placed outside the driver 4700, assembly and management can not be easy, and resonance of the slider 4600 can cause noise. In addition, the structures of the slider 4600 and the driver 4700 are dispersed, making modularization difficult.

[0012] (Patent Document 1) Korean Patent No. 10-2144784 SUMMARY

[0013] TECHNICAL PROBLEM

[0014] One object of the present disclosure is to solve the above and other problems.

[0015] Another object of the present disclosure is to provide a flush handle of a vehicle door that is very advantageous in terms of cost reduction by pushing a latch lever while a single lever is lowered when pulling out a handle unit to open a door.

[0016] Another object of the present disclosure is to provide a flush handle of a vehicle door that is very advantageous in terms of compactness, durability, and economy by detecting an initial position and a pop-out position of a handle unit without using a separate switch member through an electrical contact detection structure.

[0017] Another object of the present disclosure is to provide a flush handle of a vehicle door that is easy to assemble and manage by modularizing a driver by directly pulling a slider through a lead screw and nut action structure placed inside the driver and is advantageous in terms of noise by eliminating resonance of the slider.

[0018] SOLUTION TO PROBLEM

[0019] To achieve the above and other objects, in one aspect of the present disclosure, there is provided a flush handle of a vehicle door including: a housing that passes through in a y-direction when a longitudinal direction of a vehicle is an x-direction, a width direction of the vehicle is the y-direction, and a height direction of the vehicle is a z-direction; a slider that is slidably disposed inside the housing; a handle unit that is slidably disposed inside the slider; a linear motion conversion unit that is configured to support relative implementation of x-direction sliding of the slider and y-direction sliding of the handle unit; a slider driver that is installed inside one side of the housing and is configured to pull the slider; a lever; and a lever driving mechanism that is configured to push and open a door latch as the lever moves downward in the z-direction when pulling out the handle unit in the y-direction.

[0020] ADVANTAGEOUS EFFECT OF INVENTION

[0021] Effects of the flush handle of a vehicle door according to the present disclosure are described as follows.

[0022] According to at least one embodiment of the present disclosure, it can be helpful to reduce costs by using one lever to push a latch lever to open a door compared to a cable.

[0023] According to at least one of the embodiments of the present disclosure, since the electrical contact takes the form of an inclined lever and is pressed and energized only at the initial position or the pop-out position, wear due to friction is small, which can be advantageous in terms of durability.

[0024] According to at least one of the embodiments of the present disclosure, since the electrical contact detection structure using a cable and a terminal is adopted, a separate switch is not required, which is advantageous in terms of cost and does not occupy much space, thereby contributing to compactness.

[0025] According to at least one of the embodiments of the present disclosure, since the lead screw unit adopts a structure of directly pulling the slider, the roles of the slider and the driver become clearer, modularization becomes possible, thus assembly and management are easy, and resonance of the slider is eliminated, which can be advantageous in terms of noise.

[0096] The electrical contact detection unit 490 can include an initial position terminal 493 and a pop-up position terminal 494 of a wire 496 disposed within the second housing 120. The initial position terminal 493 and the pop-up position terminal 494 are connected to a connector 495 via the wire 496. The connector 495 can be installed outside of one side of the second housing 120.

[0097] Thus, when the press protrusion 455c is located on the left side as shown, FIG. 7 the left side 491b of the initial position tilting lever 491 is pressed and contacts the initial position terminal 493, which is powered on. On the other hand, the right side 492b of the pop-up position tilting lever 492 is not pressed and detects power off.

[0098] When the press protrusion 455c is located on the right side as shown, FIG. 14 and FIG. 21 the right side 492b of the pop-up position tilting lever 492 is pressed and contacts the pop-up position terminal 494, which is powered on. On the other hand, the left side 491b of the initial position tilting lever 491 is not pressed and detects power off.

[0099] As described above, when the pressing protrusion 455c moves to the left and right, only the floating portions such as the left side 491b of the initial position tilt lever 491 and the right side 492b of the pop-up position tilt lever 492 are pressed, thereby preventing power failure and a decrease in recognition rate by eliminating the grinding phenomenon of parts caused by continuous friction.

[0100] By arranging brass plate terminals according to their positions, the initial position tilt lever 491 and the pop-out position tilt lever 492 can be energized to detect the initial position and pop-out position of the handle unit 300.

[0101] The initial position tilt lever 491 and the pop-out position tilt lever 492 can form a pair.

[0102] <Lever Drive Mechanism 500>
