A striker catching protrusion 2204 in which the striker 2001 is caught may be formed at the latch 2200.

A right surface of the striker catching protrusion 2204 may be formed to bend such that the center protrudes to the right. The locking groove 2201 may be positioned under the center.

Hence, the striker 2001 can be smoothly inserted into the locking groove 2201 along a slope of the striker catching protrusion 2204. When the striker 2001 is inserted into the locking groove 2201, it may be difficult for the striker 2001 to come out of the front due to the protrusion of the striker catching protrusion 2204.

An auxiliary locking groove 2202 may be formed at the right side of the locking groove 2201 in the latch 2200.

The auxiliary locking groove 2202 may be formed between a first locking catching portion 2202a and a second locking catching portion 2201a in which the locking portion 2371 is caught.

The auxiliary locking groove 2202 may be formed in a shape similar to the locking groove 2201 while having a narrower depth than the locking groove 2201. That is, a distance between the auxiliary locking groove 2202 and the center of rotation of the latch 2200 may be larger than a distance between the locking groove 2201 and the center of rotation of the latch 2200.

The locking groove 2201 and the auxiliary locking groove 2202 may be spaced from each other along a circumferential direction.

When closing the vehicle door, the locking portion 2371 of the pivoting member 2370 may be first inserted into the auxiliary locking groove 2202 and then inserted into the locking groove 2201.

A spring fitting portion 2207 may be formed at the lower outer circumferential surface of the latch 2200.

The spring fitting portion 2207 may be formed in a protrusion shape, and the other end 2253 of the first return spring 2250 may be caught in the spring fitting portion 2207 and mat rotate together with the latch 2200.

A protrusion 2208 may be formed on the left outer circumferential surface of the latch 2200 to protrude outward.

The protrusion 2208 may be disposed in front of the catching portion guide groove 2115.

A latch catching portion 2532 of the cinching lever 2530 to be described below may be fitted to a lower part of the protrusion 2208, and the latch 200 may rotate by the latch catching portion 2532.

A plurality of auxiliary grooves that is recessed in a radial direction may be formed around the elastic cover groove 2211.

Hence, a friction force generated between the elastic cover 2210 and the latch pivot shaft 2230 when the elastic cover 2210 is pivoted can be reduced. In addition, since a lubricant (grease) can be accommodated in the auxiliary grooves of the elastic cover groove 2211 for a long time, the performance can be improved.

Slits 2212 may be formed in the elastic cover 2210. The slits 2212 may be respectively formed in a portion abutting on the bumper member 2360 disposed on the upper part of the first housing 2110 and in a portion abutting on the striker 2001. The slits 2212 can reduce an impact generated when the latch 2200 abuts on other members.

The first return spring 2250 may be provided so that the latch 200 is automatically returned upon the unlocking.

One end 2252 and other end 2253 of the first return spring 2250 may be formed to correspond to an assembly shape. The one end 2252 may be extended to the left side, and the other end 2253 may be bent forward at a right angle.

A latch insertion groove 2372, into which the second locking catching portion 2201a and the first locking catching portion 2202a of the latch 2200 are inserted when the vehicle door is closed, may be formed on a lower part of the locking portion 2371. The latch insertion groove 2372 may be opened downward and disposed between the locking portion 2371 and the catching protrusion 2373. Due to the latch insertion groove 2372, a state in which the latch 2200 is locked to the pivoting member 2370 when the vehicle door is closed can be stably maintained.

The catching protrusion 2373 may be formed on the right side of the lower surface of the locking portion 2371 to protrude downward.

A pivoting member catching portion 2351 of the open lever 2350 may be inserted into the left side of the catching protrusion 2373. That is, the catching protrusion 2373 may serve to pivot the pivoting member 2370 according to the rotation of the open lever 2350.

The pivoting member 2370 may rotate by being linked to the rotation and movement of the open lever 2350.

As in the latch 2200 described above, the pivoting member 2370 may also be provided with an elastic cover 2375. The elastic cover 2375 may be formed of a material with elasticity such as rubber and can absorb an impact applied to the pivoting member 2370 and prevent a noise. The elastic cover 2375 may be formed to surround the remaining portion excluding the locking portion 2371 from the pivoting member 2370.

A groove into which the pivot shaft 2380 is inserted may be formed on an upper part of the elastic cover 2375 of the pivoting member 2370 to be penetrated in the front-rear direction, and an auxiliary groove may be formed in the groove to be recessed in a radial direction. Hence, a friction force generated between the elastic cover 2375 and the pivot shaft 2380 when the elastic cover 2375 is pivoted can be reduced. In addition, since a lubricant (grease) can be accommodated in the auxiliary groove for a long time, the performance can be improved.

A cover protrusion 2376 inserted into the spring insertion groove 2117 of the first housing 2110 may be formed in the rear of the elastic cover 2375.

Due to the cover protrusion 2376, the elastic cover 2375 and the pivoting member 2370 may not move to the left side more than the spring insertion groove 2117,

The pivot shaft 2380 may be installed to pass through upper parts of the pivoting member 2370 and the elastic cover 2375.

A catching plate 2381 may be formed in the middle of the pivot shaft.

The pivoting member 2370 may be inserted into the front of the catching plate 2381, and the pivoting member spring 2390 may be inserted into the rear of the catching plate 2381. Hence, when the pivoting member 2370 rotates, friction between the front surface of the pivoting member spring 2390 and the rear surface of the pivoting member 2370 can be prevented.

The first housing 2110 may be inserted into the rear of the pivoting member spring 2390.

A diameter of a front end of the pivot shaft 2380 may be less than diameters of other ends of the pivot shaft 2380. The front end of the pivot shaft 2380 may be assembled to the second housing 2130, and the rear end of the pivot shaft 2380 may be assembled to the reinforcement plate 2340.

That is, the second housing 2130, the pivoting member 2370, the pivoting member spring 2390, the first housing 2110, and the reinforcement plate 2340 may be installed on the pivot shaft 2380 in the order named from the front of the pivot shaft 2380.

The pivoting member 2370 can pivot clockwise or counterclockwise about the pivot shaft 2380.

Based on the center of the rotation lever 4500, the pivot shaft installation groove 4501 may be disposed on the left side of the center, and the separation plate 4504 may be disposed on the right side of the center.

The rotation lever 4500 may not move forward due to the separation plate 4504 and the boss formed in front of the pivot shaft installation groove 4501.

With reference to FIGS. 15 to 19, a cinching driving method in the latch part 2000 is described below.

As illustrated in FIG. 15, a state in which the striker 2001 is outside the latch part 2000 is referred to as an initial state. In this instance, the latch 2200 does not rotate by the striker 2001, and the third sensor transfer member 2911 and the fourth sensor transfer member 2912 are not pressed by the latch 2200.

As illustrated in FIGS. 16 and 17, when the striker 2001 is inserted into the locking groove 2201 of the latch 2200 through the striker insertion groove 2105, the latch 2200 may rotate clockwise.

When the vehicle door is closed while the first locking catching portion 2202a of the latch 2200 is caught in the locking portion 2371 of the pivoting member 2370, only the fourth sensor transfer member 2912 may be pressed by the latch 2200.

When the fourth sensor transfer member 2912 is pressed and the third sensor transfer member 2911 is not pressed, the controller may recognize this as a state in which the vehicle door is incompletely closed, and may pull the cinching connector 80 using the actuator 3000 so as to perform the cinching function.

So, as illustrated in FIGS. 18 and 19, the cinching lever 2530 may rotate clockwise by the cinching connector 80.

When the cinching lever 2530 rotates clockwise, the latch catching portion 2532 of the cinching lever 2530 may rotate the latch 2200 clockwise, and the second locking catching portion 2201a of the latch 2200 may be caught in the locking portion 2371 of the pivoting member 2370. In this instance, the third sensor transfer member 2911 and the fourth sensor transfer member 2912 may be pressed by the latch 2200, and the controller may recognize this as a state in which the vehicle door is completely closed, and may return the cinching connector 80 to its originals state.

With reference to FIGS. 25 to 28, a cinching driving method in the actuator 3000 is described below.

As illustrated in FIGS. 25 and 26, a state in which both the catching protrusion 74 of the pusher connector 70 and the catching protrusion 81 of the cinching connector 80 are not pulled is referred to as an initial state.

In this instance, the first sensor 3001 may be maintained in a depressed state by the sensor pressing portion 3443 of the pusher pull member 3440.

When the cinching function is performed by the controller, the driving motor 3410 may rotate. When the driving motor 3410 rotates, the first gear 3412 may rotate along the driving motor 3410. Further, when the first gear 3412 rotates, the second gear 3420 engaged with the first gear 3412 may rotate.

As illustrated in FIGS. 27 and 28, when the second gear 3420 rotates, the lead screw 3431 engaged with the second gear 3420 may slide rearward.

Hence, the cinching pull member 3430 provided with the lead screw 3431 can slide rearward, and the catching protrusion 84 of the cinching connector 80 can be pulled rearward.

As the cinching pull member 3430 slides rearward, the pusher pull member 3440 coupled with the cinching pull member 3430 may also slide rearward.

Hence, the sensor pressing portion 3443 of the pusher pull member 3440 can deviate from the first sensor 3001 and can press the second sensor 3002.

When the second sensor 3002 is pressed, the driving motor 3410 may stop working.

Since the catching protrusion 84 installed in the actuator 3000 and the catching protrusion 81 installed in the cinching lever 2530 are connected to each other through the cable 83, the catching protrusion 81 installed in the cinching lever 2530 may also be pulled toward the actuator 3000 and rotate the cinching lever 2530.

In this instance, the pusher connector installation groove 3445 of the pusher pull member 3440 may be sufficiently extended in the front-rear direction so that it does not affect the catching protrusion 74 of the pusher connector 70.

When the controller recognizes that the vehicle door is completely closed, the driving motor 3410 may rotate in the opposite direction and returns the cinching pull member 3430 to the initial state.

With reference to FIGS. 34 to 37, a pusher driving method in the pusher part 4000 is described below.

As illustrated in FIGS. 34 and 35, a state in which the pusher connector 70 is not pulled is referred to as an initial state.

When a signal to perform a door open function is transmitted to the controller while the latch part 2000 is unlocked, the pusher connector 70 may be pulled.

As illustrated in FIGS. 36 and 37, when the pusher connector 70 is pulled, the sliding member 4300 in which the catching protrusion 71 of the pusher connector 70 is installed may slide downward.

When the sliding member 4300 slides downward, one side of the rotation lever 4500 may be forced downward, and the rotation lever 4500 may rotate counterclockwise. Further, other side of the rotation lever 4500 may transmit a force upward, and the pusher 4400 may slide upward.

In this instance, when the rotation lever 4500 turns counterclockwise, the second end 4512 of the rotation lever return spring 4510 may approach the first end 4511, and the rotation lever return spring 4510 may be retracted.

The user may push the vehicle door in the direction in which the vehicle door opens while the pusher 4400 protrudes more upward than the first and second pusher cases 4100 and 4200. A gap may be formed between the vehicle door and the vehicle body to the extent that the user can put his/her hand.

In this instance, the door open button 4402 may press the door open sensor 4403 while the door open button 4402 of the pusher 4400 is pressed.

Afterwards, when the user puts his/her hand in the gap and opens the vehicle door enough to allow the user to enter, an external force applied to the door open button 4402 of the pusher 4400 is removed. Therefore, the door open button 4402 returns to its original state, and the door open sensor 4403 is not pressed.

When the signal from the door open sensor 4403 disappears, the controller may recognize that the vehicle door has been opened, rotate the actuator 3000 in the reverse direction, and return the pusher connector 70 to the initial state.

When the pusher connector 70 is returned to the initial state, the pusher part 4000 is returned to its original state by an elastic restoring force of the rotation lever return spring 4510.

With reference to FIGS. 25 and 26 and FIGS. 29 and 30, the pusher driving method in the actuator 3000 is described below.

In this instance, the first sensor 3001 may be maintained in a depressed state by the sensor pressing portion 3443 of the pusher pull member 3440.

When the pusher function is performed by the controller, the driving motor 3410 may rotate in the opposite direction to when the cinching function is performed. When the driving motor 3410 rotates, the first gear 3412 may rotate along the driving motor 3410. Further, when the first gear 3412 rotates, the second gear 3420 engaged with the first gear 3412 may rotate.

As illustrated in FIGS. 29 and 30, when the second gear 3420 rotates, the lead screw 3431 engaged with the second gear 3420 may slide forward.

Hence, the cinching pull member 3430 provided with the lead screw 3431 and the pusher pull member 3440 coupled with the cinching pull member 3430 may slide forward, and the catching protrusion 74 of the pusher connector 70 may be pulled forward. Further, the sensor pressing portion 3443 of the pusher pull member 3440 may deviate from the first sensor 3001, and the third sensor pressing plate 3436 of the cinching pull member 3430 may press the third sensor 3003.

When the third sensor 3003 is pressed, the driving motor 3410 may stop rotating.

Since the catching protrusion 74 installed in the actuator 3000 and the catching protrusion 71 installed in the pusher part 4000 are connected to each other through the cable 73, the catching protrusion 71 installed in the pusher part 4000 may also be pulled toward the actuator 3000 and may slide downward the sliding member 4300.

In this instance, the cinching connector installation groove 3437 of the cinching pull member 3430 may be sufficiently extended in the front-rear direction so that it does not affect the catching protrusion 84 of the cinching connector 80.

As described above, when the controller checks that the vehicle door opens, the driving motor 3410 may rotate in the opposite direction and return the pusher pull member 3440 to the initial state.

As described above, the first embodiment of the present disclosure can operate only the cinching function by removing the pusher connector 70 and the pusher part 4000 that is connected to the pusher connector 70 and is installed in the second housing 2130.

Because the pusher part 4000 is modularized, the user can easily remove the pusher function, if necessary or desired.

Second Embodiment

As illustrated in FIG. 38, an electric latch (E-latch) for vehicle door according to a second embodiment of the present disclosure may include an actuator 3000 connected to a latch part 2000′ locking or unlocking a vehicle door, and a pusher part 5000 that is connected to the actuator 3000 and creates a space to grab the vehicle door by making a distance between the vehicle door and a vehicle body.

The actuator 3000 and the pusher part 5000 may be connected by a pusher connector 90.

In the second embodiment of the present disclosure, structures and components identical or equivalent to those described in the first embodiment are designated with the same or similar reference numerals, and a further description may be briefly made or may be entirely omitted.

Configuration of the latch part 2000′ according to the second embodiment of the present disclosure is substantially the same as configuration of the latch part 2000 according to the first embodiment of the present disclosure, except for a second housing 2160.

The second housing 2160 is illustrated in detail in FIGS. 39 and 40.

The second housing 2160 may be formed in a plate shape.

The right side of the second housing 2160 may be substantially the same as the right side of the second housing 2130 according to the first embodiment of the present disclosure.

A pusher installation groove 2161 that is penetrated in a front-rear direction may be formed in the left side of the second housing 2160. A boss may be formed in the rear of the pusher installation groove 2161.

A fifth protrusion 2163 may be formed on the left side of the second housing 2160 in an arc shape centered on the pusher installation groove 2161 to protrude rearward.

The boss formed in the rear of the pusher installation groove 2161 and the fifth protrusion 2163 may protrude rearward with the same length. The boss formed in the rear of the pusher installation groove 2161 and the fifth protrusion 2163 may abut on a front surface of the pusher part 5000 to be described below to reduce a friction force between the pusher part 5000 and the second housing 2160.

A pusher connector installation member 2168 that is bent rearward may be formed at a left end of the second housing 2160.

The pusher connector installation member 2168 may be formed on a lower part of the second housing 2160.

A pusher connector installation groove 2169 of which the rear is opened may be formed in the pusher connector installation member 2168.

The pusher part 5000 is illustrated in detail in FIGS. 39 and 40.

The pusher part 5000 may include a rotation lever 5100 rotatably installed on the second housing 2160, and a door open roller 5110 that is installed on one side of the rotation lever 5100 and pushes the vehicle door in a direction in which the vehicle door opens.

The rotation lever 5100 may include a first plate formed in a left-right direction and a second plate formed on the right side of the first plate to protrude downward.

A pivot shaft insertion groove 5101 that is penetrated in the front-rear direction may be formed at a point where the first plate and the second plate of the rotation lever 5100 meet.

The pivot shaft insertion groove 5101 and the pusher installation groove 2161 of the second housing 2160 may communicate with each other and may be coupled by a pivot shaft 5120.

That is, the rotation lever 5100 may be rotatably installed on the pivot shaft 5120.

A catching protrusion installation member 5102 that is bent rearward may be formed on a lower part of the second plate of the rotation lever 5100.

A lower end of the catching protrusion installation member 5102 may be bent to the right side. That is, the catching protrusion installation member 5102 may be formed in an L-shape.

A catching protrusion installation groove 5103 that has an opened lower part and is penetrated in the left-right direction may be formed in the catching protrusion installation member 5102. A width of the catching protrusion installation groove 5103 may be greater than a width of a cable 93 of the pusher connector 90 to be described below and may be less than a diameter of a catching protrusion 91.

Hence, when the catching protrusion 91 is installed in the catching protrusion installation groove 5103, the catching protrusion 91 does not retreat to the lower and the left due to the shape of the catching protrusion installation member 5102. The catching protrusion 91 may be pulled to the left as illustrated in FIGS. 41 and 42.

The door open roller 5110 may be formed in a disc shape.

The door open roller 5110 may be rotatably installed on the rotation lever 5100.

Hence, when the rotation lever 5100 rotates, the door open roller 5110 may roll along the inner surface of the vehicle door and smoothly push the vehicle door in a direction in which the vehicle door opens.

The pusher connector 90 according to the second embodiment of the present disclosure may be entirely similar to the pusher connector 70 according to the first embodiment of the present disclosure.

The catching protrusion 91 formed on one side of the pusher connector 90 may be fitted to the rotation lever 5100, and a catching protrusion fixing portion 92 may be installed in the second housing 2160.

A catching protrusion return spring 95 may be installed between the catching protrusion 91 and the catching protrusion fixing portion 92. That is, the catching protrusion return spring 95 may be installed between the catching protrusion installation member 5102 of the rotation lever 5100 and the pusher connector installation member 2168 of the second housing 2160.

Other side of the pusher connector 90 may be installed at the actuator 3000 in the same manner as the pusher connector 70 according to the first embodiment of the present disclosure.

The pusher connector 90 may transmit a driving force of the actuator 3000 to the rotation lever 5100.

With reference to FIGS. 41 and 42, a pusher driving method in the pusher part 5000 is described below.

A pusher driving method in the actuator 3000 in the second embodiment of the present disclosure may be substantially the same as the driving method in the first embodiment of the present disclosure.

As illustrated in FIG. 41, a state in which the pusher connector 90 is not pulled by the actuator 3000 is referred to as an initial state.

When a signal to perform a door open function is transmitted to the controller while the latch part 2000′ is unlocked, the actuator 3000 may operate and pull the pusher connector 90.

As illustrated in FIG. 42, when the pusher connector 90 is pulled to the left, the rotation lever 5100 may rotate clockwise around the pivot shaft 5120.

When the rotation lever 5100 rotates clockwise, the door open roller 5110 may protrude upward and push the vehicle door in a direction in which the vehicle door opens. At the same time, the catching protrusion installation member 5102 may approach the pusher connector installation member 2168, and the catching protrusion return spring 95 may be retracted.

When the pusher connector 90 is pulled and a third sensor 3003 of the actuator 3000 is pressed, the driving motor 3410 stops working. After a predetermined time has passed, the driving motor 3410 may rotate in the opposite direction, and the pusher connector 90 may be returned to the initial state.

When the pusher connector 90 is returned to the initial state, the catching protrusion return spring 95 may push the catching protrusion installation member 5102 of the rotation lever 5100 by an elastic restoring force of the catching protrusion return spring 95, and the rotation lever 5100 may be returned to the original state.

It is apparent to those skilled in the art that the present disclosure can be embodied in other specific forms without departing from the spirit and essential features of the present disclosure. Accordingly, the aforementioned detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the present disclosure should be determined by rational interpretation of the appended claims, and all modifications within an equivalent scope of the present disclosure are included in the scope of the present disclosure.
