[0139] In the first case 1110 is the back of the locking element receiving recess 1112 for accommodating the locking sub-element 1400 formed so that it is open, so here the lever guide part 1507 , which will be described later, can be introduced.

[0140] A load guide recess 1116 is in the left-right direction at the front of the first case 1110 formed so that they with the locking member-receiving recess 1112 connected.

[0141] The load guide recess 1116 is in the lower part of the halyard mounting hole 1111 arranged.

[0142] A first sensor element insertion hole 1128 is in the left-right direction at the front of the first case 1110 formed so that they with the locking member-receiving recess 1112 and the load guide recess 1116 connected.

[0143] The first sensor element insertion hole 1128 is in the lower left part of the locking element receiving recess 1112 arranged.

[0144] The first sensor element insertion hole 1128 is shaped so that its bottom and back are open. A first spring receiving recess 1117 and a second spring receiving recess 1119 are in the front right side of the first case 1110 educated. The first spring receiving recess 1117 and the second spring receiving recess 1119 are on the right side of the locking element receiving recess 1112 arranged and stand with the locking element receiving recess 1112 in connection. The lead-out holes, through which the wires connected to the inner door handle and the outer door handle are taken out, face the right side of the first spring receiving recess 1117 and the second spring receiving recess 1119 in connection.

[0145] As in figure 24 shows a manual locking member insertion hole 1118 , into which the manual locking element 1560 is inserted continuously from front to back between the first spring receiving recess 1117 and the second spring receiving recess 1119 .

In addition, after completion of the assembly, the top of the buffer member insertion hole 1123 , which is arranged in the upper area, through the second housing 1130 closed, which will be described later in more detail. In this way, the assembling becomes very easy because the buffer member insertion hole arranged in the upper part 1123 is shaped like this.

[0152] The buffer element located in the lower part 1360 carries the trap 1200 , so as to prevent any crack from occurring when the trap 1200 through the locking element 1300 is in a locking state, and the buffer member arranged in the upper part 1360 supports the trap 1200 such that the trap 1200 is rotated by a predetermined angle when the trap 1200 due to the restoring force of the first return spring 1250 rotates counterclockwise after locking by the locking member 1300 is released, and thus a gap, noise and vibration are prevented from occurring.

[0153] In the front surface of the first housing 1110 is a plurality of support projections lengthwise 1103 formed that the horizontal part or the vertical part of the lower part of the second housing 1130 carry. Because of these support projections 1103 becomes the pre-assembly of the first case 1110 and the second housing 1130 simplified. This facilitates assembly.

[0154] In the top surface of the first case 1110 is a concave part 1124 educated.

[0291] The fronts of the first stop member receiving recess 1401a and the second stopper receiving recess 1401b are open.

[0292] The first stop member receiving recess 1401a and the second stopper receiving recess 1401b are shaped to match the shapes of the first stop member 1801a and the second stop element 1801b correspond. Therefore, a separation of the first stopper member 1801a and the second stop element 1801b from the locking sub-element 1400 prevented even if the inside door handle or the outside door handle is pulled.

[0293] The first stop element 1801a , which is at the end of the interior door handle connection unit 1800a is formed is in the first stopper-receiving recess 1401a recorded.

[0294] The first stop element 1801a the interior door handle connection unit 1800a , Inside the first stop member receiving recess 1401a arranged may change due to the presence of the body 1310 of the locking main element 1300 do not loosen towards the front.

[0298] Thus, the first locking sub-element 1400a shifted to the right when the interior door handle connection unit 1800a is pulled to the right.

[0299] A second extraction hole 1403b , with the help of which the outside door handle connection unit 1800b is pulled is connection-wise on the right side of the second stopper-receiving recess 1401b formed so that the second pull-out hole 1403b a smaller diameter than the second stop member 1801b has, so that the second stop element 1801b even then not through the second extraction hole 1403b can be pulled through if the outside door handle connection unit 1800b is pulled to the right.

[0300] Thus, the second locking sub-element 1400b shifted to the right when the outside door handle connection unit 1800b is pulled to the right.

[0301] A first feather 1803a is in the interior door handle connection unit 1800a near the first stop element 1801a deployed.

[0302] A first spring insertion projection 1402a and a second spring insertion projection 1402b are in a rightwardly projecting manner at the right side ends of the first locking sub-member 1400a and the second locking sub-element 1400b and above and below the first pull-out hole 1403a and the second pull-out hole 1403b arranged. The left ends of the first spring 1803a and the second spring 1803b are respectively in the first spring insertion projection 1402a and the second spring insertion projection, respectively 1402b introduced.

[0303] The first feather 1803a is between the right end of the first locking sub-element 1400a and the first spring receiving recess 1117 of the first housing 1110 arranged. The first feather 1803a moves the first locking sub-element 1400a , which has been shifted to the left by an external force, returns to its original position by pushing it back using the elastic restoring force of the first spring 1803a shifts to the left when the external force is no longer applied.

[0304] The second feather 1803b is in the outside door handle connection unit 1800b deployed.

[0305] The second feather 1803b is between the right end of the second latch sub-member 1400b and the second spring receiving recess 1119 of the first housing 1110 arranged. The second feather 1803b moves the second locking sub-member 1400b , which has been shifted to the left by an external force, returns to its original position by pushing it back using the elastic restoring force of the second spring 1803b shifts to the left when the external force is no longer applied.

[0306] A stop threshold 1405 , where the stopper projection 1455 the stop lever unit 1450 held or captured is on the locking sub-element 1400 educated. The stop threshold 1405 includes a first stop threshold 1405a and a second stop threshold 1405b .

[0307] The first stop threshold 1405ais in the back of the first locking sub-element 1400a formed, and the second stop threshold 1405b is in the back of the second stop sub-element 1400b educated.

[0308] The first stop threshold 1405a and the second stop threshold 1405b are shaped so that the left sides of the back sides of the first locking sub-element 1400a and the second locking sub-element 1400b project further back than their right sides.

[0309] The right surfaces of the first stop threshold 1405a and the second stop threshold 1405b are formed so inclined that the stopper projection 1455 cannot be readily separated from them once engaged with them.

[0310] The stop protrusion 1455 of the first stop lever part 1450a can from the first stop threshold 1405a to be engaged or separated therefrom, and the protrusion 1455 of the second stop lever part 1450b can of the second stop threshold 1405b recorded or separated from it.

[0311] The first stop lever part 1450a , the second stop lever part 1450b , the first stop threshold 1405a and the second stop threshold 1405b are connecting devices to the locking main element 1300 and the locking sub-element 1400 together or only the locking sub-element 1400 move alone.

[0312] When the first stop lever part 1450a from the first stop threshold 1405a is detected and the second stop lever part 1450b from the second stop threshold 1405b is engaged and when the inside door handle (not shown) or the outside door handle (not shown) is pulled, then the lock main element 1300 and the locking sub-element 1400 pulled together to the left.

[0313] That is, this is an unlocked state of the door 1 . In contrast, when the first stop lever part 1450a from the first stop threshold 1405a is separated and the second stop lever part 1450b from the second stop threshold 1405b is disconnected and when the inside door handle (not shown) is pulled, the latch body remains 1300 in place and only the locking sub-element 1400 is shifted to the left.

[0314] That is, this is a locked state of the door 1 . The first locking sub-element 1400a is with a manual locking element pressing part 1407 provided, which extends from the lower area of ​​the right surface to the right, i.e. outwards.

[0315] The manual locking element pressing part 1407 is provided with a horizontal plate whose front face projects further than the front face of the first locking sub-member 1400a .

[0316] The manual locking element pressing part 1407 is between the first spring seat recess 1117 of the first housing 1110 and the second spring receiving recess 1119 arranged and is simultaneously with the first locking sub-element 1400a shifted in left-right direction.

[0317] The manual locking element pressing part 1407 is in contact with the first stopper 1563 of the manual locking element 1560 , which will be described later.

[0318] As in figure 13 is the locking plate 1500 elongated in the left-right direction. The locking plate 1500 is slidably in the lower rear surface of the first housing 1110 Installed. The locking plate 1500 rotates the stopper lever unit 1450 .

[0319] The locking plate 1500 includes a unlocking cable connector 1501 , a lever guide part 1507 , a hand lock guide slotted hole 1515 and a second sensor element 1519 .

[0320] The unlocking cable connection part 1501 is in the area of ​​the left end of the locking plate 1500 arranged.

[0321] A release cable 1810 is with the left end of the unlock cable connector 1501 connected and the unlock cable 1810 is pulled forward to the right or left when the button (not shown) or the like is operated so that the lock plate 1500 is moved to the left or to the right.

[0322] A stopper receiving recess, in which the end of the unlocking cable is received, is on the rear surface of the unlocking cable connecting part 1501 educated. This will complete the assembly of the unlocking cable 1810 with the locking plate 1500 simplified.

[0323] The stop element of the unlocking cable 1810 has the shape of an elongated cylinder pointing downwards.

[0324] A bent element 1503 , which is backwards to the lower right area of ​​the release cable connection part 1501 is formed above is on the locking plate 1500 intended.

[0325] The bent element 1503 has the shape of a horizontal plate.

[0326] A stop protrusion 1506 is at the bottom of the bent element 1503 formed downwards.

[0327] The stop protrusion 1506 is a circular projection and is used for manual displacement of the locking plate 1500 using a key connector 1550 .

[0328] The key connector 1550 includes the following: a head 1551 in which a cross-shaped slit is formed; a wing 1553 , which has a key connector opening 1555 having a portion of a disc that is larger in diameter than the head 1551 has, is truncated, and an upper projection 1557 , coming from the middle of the wing 1553 protrudes upwards.

[0329] The key connector 1550 is in a rotatable manner in the lower part of the housing 1100 installed and the stop tab 1506 is inside the key connector opening 1555 of the key connector 1550 arranged.

[0330] At the time when the head 1551 of the key connector 1550 is rotated by hand using a tool such as a wrench or a screwdriver or the like, the lock plate can 1550 be shifted in left-right direction without removing them from the drive unit 1600 is driven.

[0331] More precisely, if the head 1551 of the key connector 1550 is rotated, the stopper projection 1506 , which is in the key connector opening 1555 is positioned at both side surfaces inside the key connector opening 1555 pushed so that the locking plate 1500 is moved in the left-right direction.

[0332] In other words: the locking plate 1500 will due to the turning movement of the key connector 1550 moved linearly.

[0333] Hence the door 1 using the key connector 1550 be locked or unlocked manually.

[0334] In addition, in the upper part of the locking plate 1500 a main gear stopper 1502 protruding upward between the unlock cable connection part and the stopper projection 1506 educated.

[0335] Furthermore, on the locking plate 1500 to the right of the main gear stopper 1502 formed a plate-like reinforcement to the lip, preventing damage to the locking plate 1500 can be avoided during operation.

[0336] If the main gear 1630 due to the working of the engine 1610 , which will be described later, is rotated, thereby becoming the main gear stopper part 1502through the first part of the stop 1633 and the second stopper part 1635 pushed forward, those on the main gear 1630 are trained. Thus, the locking plate 1500 moved to the right or to the left.

[0337] The Main Gear 1630 is at the top of the main gear stopper part 1502 arranged so that only the main gear stop part 1502 is captured while the other parts of the locking plate 1500 not be detected when the main gear 1630 turns.

[0338] On the locking plate 1500 is a lever guide part 1507 to the right of the bent element 1503 educated.

[0339] A lever guide part 1507 is on the front of the right section of the locking plate 1500 formed to protrude forward (towards the stopper lever part 1450 ).

[0340] The lever guide part 1507 is in the form of a strip and is formed so that it first protrudes and then is bent to the right. This creates an insertion space 1509 , into which the guide rod 1457 is inserted between the lever guide part 1507 and the locking plate 1500 educated. The insertion room 1509 is formed so that its upper side, lower side and right side are open.

[0341] An inclined surface 1511 is on the inner side surface (the surface that connects to the guide rod 1457 comes into contact) of the lever guide part 1507 is formed and thereby the structure becomes simpler and the durability is also increased. Because of this inclined surface 1511 becomes the thickness of the right side of the lever guide part in the front-rear direction 1507 larger towards the left.

[0342] The upper part of the lever guide part 1507 leads the first pole 1457a of the first stop lever part 1450a and the lower portion of the lever guide part 1507 guides the second guide rod 1457b of the second stop lever part 1450b .

[0343] The rotation of the stop lever unit 1450 occurs when the lever guide part 1507 the guide rod 1457 leads either forwards or backwards; when the stop lever unit 1450 from the threshold 1405 due to a displacement of the locking plate 1500 is detected, then move the locking main element 1300 and the locking sub-element 1400 together (the door lock is released) and when the stopper lever unit 1450 due to a displacement of the locking plate 1500 from the threshold 1405 is separated, then only the locking sub-element moves 1400 (the door will be locked).

[0344] More precisely, when the first guide rod 1457a and the second guide rod 1457b in the insertion room 1509 through the lever guide part 1507 are arranged, the first stop lever part 1450a and the second stop lever part 1450b from the first stop threshold 1405a of the first locking sub-element 1400a or the second stop threshold 1405b of the second locking sub-element 1400b disconnected, and this is the state in which the door 1 is locked.

[0345] When the first guide rod 1457a and the second guide rod 1457b from the insertion room 1509 are separated, the first stop lever part 1450a and the second stop lever part 1450b from the first stop threshold 1405a of the first locking sub-element 1400a or the second stop threshold 1405b of the second locking sub-element 1400b detected, and this is the state in which the locking of the door 1 is lifted.

[0346] Thus, the lever guide part plays 1507 through the roll, door 1 to lock or locking the door 1 cancel that he is the first stopper lever part 1450aand the second stop lever part 1450b according to the displacement of the locking plate 1500 rotates in left-right direction.

[0347] A hand lock guide slotted hole 1515 is in the left-right direction at the top of the right end of the lock plate 1500 educated. The hand lock guide slot hole 1550 is shaped so that its front, back and right side are open.

[0348] A reinforcement structure is near the manual latch guide slot hole 1515 in the front face of the locking plate 1500 formed, whereby the resistance of the locking plate is increased.

[0349] A second attachment part 1562 of the manual locking element 1560 , which will be described later, is in the manual lock guide slot hole 1515 introduced.

[0350] In the central area of ​​the main locking element 1560 a shaft through-hole is formed through the top-bottom direction through which the manual lock member shaft 1561 runs.

[0351] The manual latch shaft 1561 is in the hand-locking element-receiving recess 1125 recorded.

[0352] The rear of the hand-locking element receiving recess 1125 is through the manual locking element cover 1564 blocked in the area of ​​the rear of the manual locking element shaft 1561 is arranged so that the manual locking element shaft 1561 not from the hand-locking element-receiving recess 1125 is separated. A second stopper outlet hole from which the second stopper 1562 pulled out is in the hand latch cover 1564 educated.

[0353] The manual locking element 1560 is in the manual locking element insertion hole 1118 introduced. Thus, the manual locking element 1560 in a rotatable manner into the first housing 1110 built-in.

[0354] A first attack part 1563 , which from the manual lock member pressing part 1407 of the first locking sub-element 1400a detected is in the front of the manual locking element 1560 formed, and a second stop part 1562 , by the locking plate 1500 is detected is formed on its back.

[0355] In this way are the first stop part 1563 and the second stopper part 1562 circumferentially spaced from each other. The corners of the end parts of the first stop part 1563 and the second stop part 1562 are rounded.

[0356] Because of such a locking element 1560 the structure is simple, and the door is unlocked when a user inside the vehicle pulls the inside door handle once when the door is locked, and the door is unlocked 1 is opened when the inner door handle is pulled again.

[0357] The locking plate 1500 is shaped such that a second sensor element 1519 in the lower area between the stop projection 1506 and the lever guide part 1507 is formed projecting downwards. More precisely, the lower part of the second sensor element 1519 shaped so that it curves backwards.

[0358] In the lower surface of the bent part of the second sensor element 1519 is a second sensor unit 1521 such as a magnet installed.

[0359] The second sensor unit 1521 is from the third sensor 1905 and the fourth sensor 1907 detected, which are installed in a position that the second sensor unit 1521 on the printed circuit board 1900 is equivalent to. Through the third sensor 1905 and the fourth sensor 1907 Detected signals are transmitted to the information device of the vehicle, so that the driver can see the locked or unlocked status of the door 1can recognize.

[0360] A first stop 1107 is either on the locking plate 1500 or the housing 1100 formed in a projecting manner, and in the other of these two parts is a first detent spring 1570 installed by the first locking tab 1107 is elastically deformed.

[0361] In this exemplary embodiment, the first detent protrusion is 1107 designed so that it attaches to the back of the first housing 1110 protrudes backwards, and the first detent spring 1570 is in the right area of ​​the back of the locking plate 1500 built-in.

[0362] A rast slot hole 1571 , through which the first locking projection 1107 protrudes through is in the lower right area of ​​the locking plate 1500 formed in the left-right direction.

[0363] A first connector 1573 , into which one end of the first detent spring 1570 inserted is to the left of the latch slot hole 1571 protruding backwards at the back of the locking plate 1500 educated.

[0364] A second connector 1572 , into which the other end of the first detent spring 1570 inserted is to the right of the latch slot hole 1571 protruding backwards at the back of the locking plate 1500 educated.

[0365] The first detent spring 1570 is formed by bending the middle part of a metal wire. Thus, the detent spring 1570 the general shape of a hairpin open to the left . In this way, a wire-shaped spring is used as the first detent spring 1570 intended.

[0366] A first introductory part 1578 , which is in the first connector 1573 is introduced is on one side of the first detent spring 1570 educated. The first introductory part 1578 has the shape of a circle.

[0367] A first rest part 1577 , whose upper and lower parts are formed to have the shape of an arc and so the shape of the first locking projection 1107 correspond to is to the right of the first insertion part 1578 the first detent spring 1570 educated. The first ledge 1107 is in the first rest part 1577 added when the locking plate 1500 is in its door locked position.

[0368] A second rest part 1575 , whose upper and lower parts are formed to have the shape of an arc and so the shape of the first locking projection 1107 correspond to is to the right of the first locking part 1577 the first detent spring 1570 educated. The first ledge 1107 is in the second rest part 1575 added when the locking plate 1500 is in the door lock release position.

[0369] In the first detent spring 1570 is an elastically deformable part 1576 , whose vertical width is smaller than that of the first locking part 1577 and the second locking part 1575 between the first locking part 1577 and the second locking part 1575 educated. That is, the vertical width of the elastically deformable part 1576 is smaller than the top-to-bottom width of the first latching portion 1107 . The upper part of the elastically deformable part 1576 is curved to be concave downwards and the lower part thereof is curved to be convex upwards.

[0370] At the right end of the first detent spring 1570 is a spring end part 1574 educated. The vertical width of the spring tail 1574 is smaller than that of the second locking part 1575 . The spring end part 1574 is arranged horizontally in the left-right direction in the form of a straight line.

[0371] The cross-sectional shape of the first locking projection 1107 is that of a cylinder.

[0372] Thus must to the locking plate 1500 to move from the connected position to the disconnected position (or to move them in the opposite direction) the vertical gap of the elastically deformable part 1576be expanded by an elastic deformation of this. That is, around the locking plate 1500 to move from the connected position to the disconnected position, or to move the locking plate 1500 To move from the disconnected position to the connected position, the locking plate must 1500 be displaced by a force strong enough to elastically deform the elastically deformable part 1576 the first detent spring 1570 to deform.

[0373] In addition, when moving the locking plate 1500 due to the contact between the elastically deformable part 1576 the first detent spring 1570 and the locking projection 1107 creates a frictional force.

[0374] Thus, moving out the lock plate 1500 prevented from the connected position or from the disconnected position even if an external impact is applied to them when the lock plate moves 1500 is in the connected position or in the disconnected position. That is, there will be accidental operation of the lock plate 1500 prevented due to an external impact.

[0375] The exemplary embodiment further includes a drive unit 1600 , which serves the trap 1200 to rotate or the locking plate 1500 to move.

[0376] As in figure 14 includes the drive unit 1600 an engine 1610 , an auxiliary gear 1620 , that from the engine 1610 is rotated, and a main gear 1630 , the one with the auxiliary gear 1620 combs and is rotated by it.

[0377] The drive unit 1600 is on the back surface of the first housing 1110 and the front surface of the third housing 1150 assembled.

[0378] The drive unit 1600 is between the rear surface of the first housing 1110 and the front surface of the third housing 1150 arranged.

[0379] The motor 1610 is with the printed circuit board 1900 so connected that he is dependent on a signal he printed from the 1900 receives, generates or does not generate a driving force.

[0380] The motor 1610 is arranged so that the angle between the shaft 1611 of the motor 1610 and the front surface of the housing 1100 is 0° (horizontal) or has a preferred value.

[0381] A snail 1613 is on the wave 1610 of the engine installed.

[0382] The auxiliary gear 1620 consists of a small diameter gear and a large diameter gear connected by a common shaft. The auxiliary gear 1620 is integrally formed of a small-diameter gear and a large-diameter gear.

[0383] The gear with the large diameter of the auxiliary gear 1620 stands with the snail 1613 engaged.

[0384] The small-diameter center spur gear of the sub-gear 1620 stands with the main gear 1630 engaged.

[0385] The Main Gear 1630 is designed as a spur gear and receives its driving force from the motor 1610 via the auxiliary gear 1620 .

[0386] As in the figure 15 and figure 16 shown is on the main gear 1630 a toothed part 1632 , on which gear teeth 1638 are formed in part of the circumference of the main gear 1630 educated; a non-toothed part 1643 , on which no gear-teeth 1638 are formed is formed in the remaining part of the circumference of the main gear.

[0387] The toothed part 1632 is only in part of the right side of the main gear 1630 educated.

[0388] The non-teeth part 1643 is in the remaining part of the main gear 1630 and not in the toothed part 1632educated. The non-teeth part 1643 is flat or curved.

[0389] That is, the gear teeth 1638 are not over the entire circumference of the main gear 1630 but only developed over a part of this circumference. Therefore, the thickness of the non-teeth part 1643 in the front-to-rear direction, reducing the strength of the main gear 1630 is maintained.

[0390] The thickness of the toothed part 1632 in the front-to-back direction is selected to be larger than that of the non-teeth portion 1643 . This increases the strength of the toothed part 1632 elevated.

[0391] The Main Gear 1630 includes a plastic part 1634 and a metal part 1642 that in the plastic part 1634 is used. The Main Gear 1603 is formed by the fact that the metal part 1642 in the plastic part 1634 is used.

[0392] The plastic part 1643 comprises a plastic plate part 1645 , which has the shape of a plate, and a toothed part 1632 , which protrudes backwards in a part of the outer peripheral surface of the plastic plate part 1645 is trained.

[0393] The plastic plate part 1645 has the shape of a circular disc and the insert projections 1637 are formed projecting rearward on the rear surface thereof. Four deployment tabs 1637 are around the insertion hole 1636 formed around, into which the main gear shaft 1114 is used.

[0394] A stop piece 1631 is in the lower left area of ​​the front surface of the plastic sheet part 1645 trained to trap 1200 to turn. The stop part 1631 is in the form of a rod or bar and is formed protruding forward.

[0395] The stop part 1631 is in an outer container 1649 , which from the front surface of the plastic plate part 1645 protrudes forward, installed slidable from front to back.

[0396] The Outer Container 1649 is shaped so that its front is open and its interior is hollow. A slide guide slotted hole 1649a is in the left and right areas of the outer container part 1649 educated. The slide guide slotted hole 1649a extends longitudinally from front to back. The slide guide slotted hole 1649a is formed to extend continuously in the left-right direction.

[0397] The rest part 1631 includes a headboard 1631a and an inner container part 1631b that attaches to the back of the headboard 1631a is trained.

[0398] In the left front of the headboard 1631a an inclined surface is formed. Because of this inclined surface, the abutment part pressing part 1330 the headboard 1631a gently push forward.

[0399] The end of the outside of the headboard 1631a is shaped to project further outward than the trap 1200 . Thus, even if the headboard 1631a from the stopper pressing part 1330 is pressed, a perturbation between the spinning trap 1200 and the stopper pressing part 1330 prevented.

[0400] The inner part of the container 1631b is in the outer container 1649 deployed.

[0401] An outer container stop protrusion 1631c is outwardly projecting on both sides of the outer periphery of the inner container 1631b educated. The Outer Tank Stop Boss 1631c is in the guide slot hole 1649a deployed.

[0402] The inner part of the container 1631b is shaped so that its back is open and its interior is hollow.

[0403] A stopper return spring 1648 , which the stop part 1631 to its original position is between the inner tank part1631b and the outer container 1649 arranged.

[0404] A coil spring is used as the return spring 1648 intended. The front end of the return spring 1648 is in the inner container 1631b introduced.

[0405] Due to such a stop part 1631 can the door 1 be opened manually by pulling on the door handle or the outside door handle even if during the closing of the door 1 using the drive unit 1600 the drive unit 1600 fails after the door is closed.

[0406] Usually the attack part plays 1631 the role that he made the trap 1200 on the main locking element 1300 in that he stops the trap 1200 automatically using the power of the motor 1610 turns when the door 1 to some extent is closed, even when the door 1 is not fully closed when a user opens the door 1 closes.

[0407] In addition, a detection part 1641 for a fifth sensor in the outer peripheral surface of the plastic sheet part 1645 formed so that it is on the back of the stopper part 1631 is arranged. The directorate part 1641 for the fifth sensor is designed such that it is on the fifth sensor 1911 presses, which is a limit switch, when the main gear 1630 returns to its base position. Thus, the main gear 1630 return to its original position (base position) after the locking plate 1500 has moved or for a movement of the trap 1200 has been rotated.

[0408] Part of the plastic part 1634 is cut off. A spur gear stopper 1502 is in the cut off space of the plastic part 1634 deployed. Because of this arrangement, a first stop part 1633 and a second stopper 1635 at the bottom of the plastic part 1634 formed around the locking plate 1500 to move. The first touch part 1633 is continuous at the bottom of the toothed part 1632 educated.

[0409] The first touch part 1633 and the second stopper part 1635 are spaced apart from each other.

[0410] The first touch part 1633 and the second stopper part 1635 play the role of locking plate 1500 shift left or right by using the main gear stopper part 1502 according to the rotation of the main gear 1630 push.

[0411] In addition, the main gear stop part 1502 on the front of the metal part 1642 arranged.

[0412] The metal part 1642 includes a plate portion 1644 having the shape of a plate, and a plurality of the projections 1639 running along the perimeter of the plate part 1644 are designed to project forward.

[0413] The plate part 1644 is disc-shaped. In the central part of the plate 1644 , are the insertion projection recesses 1646 around the insertion hole 1636 formed, in which the case-rotary shaft 1230 is used. The insertion tabs 1637 are in the insertion boss recesses 1646 introduced.

[0414] The ledges 1639 are in the toothed part 1632 and inside the stop part 1631 of the plastic part 1634 introduced. Thus, the durability of the toothed part 1632 and the stop part 1631 be further increased.

[0415] The ledges 1639 , which in the toothed part 1632 are introduced, are formed divided into several parts and the projection 1639 , which is inside the stop part 1631 is arranged has a greater length than the projections 1639 inside the toothed part 1632 .

[0416] Since opening and closing the door 1 using the trap 1200 and locking and unlocking the door 1 using the locking plate 1500 by a single drive unit 1600 can be accomplished, the structure becomes simple, the configuration compact, and the manufacturing cost can be reduced.

[0417] As in figure 17 is the child latch 1700 slidably so in the housing 1100 installed to slide left-right-R direction and in the upper part of the locking sub-element 1400 is arranged.

[0418] More specifically, the child locking element 1700 in the upper part of the first locking sub-element 1400a arranged.

[0419] The child locking element 1700 is in the form of a plate and is in the child latch receiving recess 1122 of the first housing 1110 recorded. Thus, the child locking element 1700 regarding the case 1100 be moved in the left-right direction.

[0420] On the child locking element 1700 is a rearwardly projecting locking tab 1722 educated. The left side face of the locking tab 1722 is inclined.

[0421] On the right front face of the child latch 1700 is a child lock operating projection 1710 designed to protrude forward. The child lock operating tab 1710 is in the operating tab slot hole 1134 introduced that in the second housing 1130 is trained.

[0422] If the child locking element 1700 is moved to the left, the child lock projection 1453 of the first stop lever part 1450a through the locking tab 1722 shifted backwards. In this way, when the right side of the first stop lever part 1450a is moved backwards, the first stop lever part 1450a from the first stop threshold 1405a Cut. And if the child locking element 1700 is moved to the right, the stopper lever part reverses 1450a back to its original state. Then the first stop lever part 1450a from the first stop threshold 1405a detected.

[0423] In this way, the stop lever part 1450a from the first stop threshold 1405a according to the movement of the child locking element 1700 be captured or separated.

[0424] A second locking projection 1721 is either on the child locking element 1700 or on the first housing 1100 formed in a projecting manner and a second detent spring 1730 that an elastic force on the second locking projection 1721 exercises is attached to the other of these natural two elements.

[0425] In this exemplary embodiment, the second detent protrusion is 1721 in the upper right area of ​​the rear surface of the child locking element 1700 formed projecting backwards, and the second detent spring 1730 is in the front face of the first housing 1110 educated. The second detent spring 1730 is on the back of the child locking element 1700 arranged.

[0426] As in figure 18 is on the front surface of the first housing 1110 a detent spring receiving recess 1104 formed so that it extends in its length in the left-right direction so that it is with the child lock member accommodating recess 1122 and at the rear of the child latch receiving recess 1122 is arranged. The detent spring receiving recess 1104 is the shape of the second detent spring 1730 designed accordingly, and the part in which an elastically deformable part 1732, which will be described later, is formed so that its vertical width is larger than that of the elastically deformable part 1732 , causing an elastic deformation of the elastically deformable part 1732 is effected.

[0427] The second detent spring 1730 is formed by bending the central part of a metallic material. Thus, the second detent spring 1730 overall the shape of a hairpin open to the left on. In this way, a wire form spring becomes the second detent spring 1730 created.

[0428] In the second detent spring 1730 is a first stop part 1731 , which is in the form of an arc corresponding to the shape of the second locking projection 1721 is formed, provided at the extreme right end of the spring. The second locking projection 1721 is in the first rest part 1731 added when the child locking element 1700 is in the connected position.

[0429] In the second detent spring 1730 is a second locking part 1733 , whose upper part and lower part are each formed in the shape of an arc, is formed in the left area. The second locking projection 1721 is in the second rest part 1733 recorded when the child locking element 1700 is in the disconnected position.

[0430] In the second detent spring 1730 is an elastically deformable part 1732 , whose vertical width is smaller than that of the first locking part 1731 and the second locking part 1733 , between the first locking part 1731 and the second locking part 1733 educated. That is, the vertical width of the elastically deformable part 1732 is smaller than the vertical height of the second locking projection 1721 . The elastically deformable part 1732 is horizontally arranged in the left-right direction in the form of a straight line.

[0431] The cross-sectional shape of the second locking projection 1721 is that of a cylinder.

[0432] Thus, the second detent spring 1730 through the second locking projection 1721 elastically deformed when the child locking element 1700 located at least partway between the connected position and the disconnected position. That is, around the child lock element 1700 to move from the connected position to the disconnected position, or to move the child latch 1700 To move from the disconnected position to the connected position, the child latch must 1700 be displaced by a force strong enough to turn the second detent spring 1730 to deform.

[0433] In addition, when the child locking element 1700 is displaced due to the contact between the elastically deformable part 1732 the second detent spring 1730 and the second locking projection 1721 creates a frictional force.

[0434] This prevents the child lock element from moving 1700 moved out of the connected position or the disconnected position even if an external impact occurs when the child latch is in the disconnected position or in the connected position. Thus, accidental actuation of the child locking element 1700 prevented due to an external impact.

[0435] A spring end piece 1734 is at the left end of the second detent spring 1730 educated. The vertical width of the spring tail 1734 is smaller than that of the elastically deformable part 1732 . The spring end part 1734 is horizontally arranged in a line in the left-right direction.

[0436] The door locking system 5 of the present invention can perform an unlocking operation without operative jamming even if the unlocking operation is performed when the door handle (not shown) is in the locked state of the door 1 is pulled.

[0437] This is described in turn below. It is assumed that on the door handle (not shown) of the door 1which is in the locked state is pulled.

[0438] At this point, because the stopper lever unit 1450 from the locking sub-element 1400 is not grasped, the locking sub-element 1400 in the opposite direction to the main locking element 1300 moved along the door handle (not shown) being pulled without affecting the main latch member 1300 Has.

[0439] When an unlocking operation is performed using a key, a remote controller, or the like, the stopper lever unit rotates 1450 forward to with the locking sub-element 1400 to be connected.

[0440] However, since the stopper lever unit 1450 kicked while pulling the door handle (not shown) is the stop lever unit 1450 not with the locking sub-element 1400 connected, spaced apart from the main locking element 1300 located; instead, the stop lever unit kicks in 1450 in that between the locking main element 1300 and the locking sub-element 1400 existing free space.

[0441] At this time, if the door handle (not shown) that was pulled is released, the latch sub-member becomes 1400 due to the elastic restoring force of the spring to the main locking element 1300 moved towards

[0442] The locking sub-element 1400 enters the inside of the stopper lever unit 1450 a, and in this way a coupling between the stopper lever unit 1450 and the locking sub-element 1400 produced.

[0443] Those in the printed circuit board 1900 of the door locking system 5 Sensors incorporated according to the present invention are connected to a room lamp (not shown), an instrument panel (not shown) and the like, so that a user can easily check the opening and closing status of the door 1 can recognize.

[0444] The following is an operation flow of the door lock system 5 , which has the above-mentioned configuration and is constructed in accordance with a third exemplary embodiment of the present invention, will be described. closing the door

[0445] As in figure 19 shown when the user pushes the door 1 closes, the door catch 1101 against the trap 1200 and the trap 1200 is rotated clockwise.

[0446] The trap 1200 presses against the sixth sensor 1910 while rotating it clockwise, and the control unit detects that the door is rotating 1 closes; the motor 1610 however not working yet. At this point expresses, as in figure 20, the outer peripheral surface of the trap 1200 against the locking tab 1320 of the locking main element 1300 and the locking main element 1300 is pushed to the right. Therefore, the first sensor unit 1351 from the first sensor 1901 not detected.

[0447] Next rotates due to the user closing the door 1 exerted force the trap 1200 continue clockwise like him figure 21 shown, and the first sensor unit 1351 is from the first sensor 1901 detected while the locking tab 1320 into the auxiliary locking recess 1201 is introduced.

[0448] In this way actuated when both the sixth sensor 1910 as well as the first sensor 1901 are detected, the control unit controls the engine 1610 .

[0449] I.e. after the trap 1200 has been rotated clockwise over a certain angle because of the trap 1200 through the door latch 1101 is pressed, the engine starts 1610 to work.

[0450] Due to this configuration, erroneous operation of the motor 1610 when opening the door1 prevented.

[0451] The lead 1215 the trap 1200 is achieved by the clockwise rotation of the stopper 1631 , attached to the front surface of the main gear 1630 is installed due to the working of the engine 1610 shifted clockwise. Consequently, the locking part 1371 of the rotating element 1370 into the locking recess 1201 the trap 1200 introduced and the door 1 hereby closed.

[0452] At this point, the locking part 1371 of the rotating element 1370 by the elastic force of the torsion spring 1390 rotated clockwise and inside the locking recess 1201 positioned, and the first surface of the trap 1200 is thereby in the case-insertion of the locking part 1371 introduced.

[0453] After the stop part 1631 through the engine 1610 been rotated and arrived in the closed position of the door, the locking part 1371 into the locking recess 1201 introduced and the first sensor unit 1351 is thereby through the first sensor 1901 detected. In this way, it is then determined when the first sensor unit 1351 through the first sensor 1901 is detected while the motor is actuated for closing the door, the control unit that the striker part 1631 is turned up to the closed position of the door and rotates using the motor 1610 the stop part 1631 counterclockwise. As in figure 22, the control unit actuates the motor 1610 , until the fifth sensor unit 1641 against the fifth sensor 1911 pushes. Thus, the main gear 1630 returned to the base position. In this way, because the main gear 1630 has been returned to the base position after the door closing or door locking operations, the driver manually releases the door locking or door locking.

[0454] When an emergency situation occurs, for example while closing the door 1 by the working of the engine 1610 If a child's fingers or clothing become trapped between the door and the vehicle body, the door handle (not shown) is pulled and the second sensor detects this 1903 the first sensor unit 1351 , which has been moved to the right, and the engine 1610 is rotated in the opposite direction and the stop part 1631 is moved to the lock release position (base position), allowing the door to be opened. locking the door

[0455] Referring to the figure 23 and figure 27 will now describe the process by which the unlocked state of the door 1 enters a locked state by a key, a lock knob, a button, an outside door handle sensor, or by the vehicle reaching a predetermined critical speed, and the like.

[0456] If the engine 1610 a door lock signal is supplied, the motor will 1610 activates and rotates the main gear 1630 counterclockwise.

[0457] If the main gear 1630 is rotated counterclockwise, the second stopper part pushes 1635 , located on the back surface of the main gear 1630 located, against the main gear stopper part 1502 the locking plate 1500 and move the locking plate 1500 .

[0458] At that moment in which the locking plate 1500 is moved to the right, as in figure 26, the first stop lever part 1450a and the second stop lever part 1450b into the insertion space 1509 along the inclined surface 1511 of the lever guide part 1507 introduced, and the stop projection 1455 is thereby moved backwards, and the stop projection 1455 is from the first locking sub-element 1400aor the second locking sub-element 1400b Cut. Because of this process, door 1 regulated; therefore, on the locking main element 1300 no force transmitted when the door handle (not shown) is pulled.

[0459] As in figure 27 shown, the second stopper projection pushes 1635 the locking plate 1500 until the second sensor unit 1521 the locking plate 1500 through the fourth sensor 1907 is detected and returns to the original position. unlocking the door

[0460] The process of changing the locked state of the door to the unlocked state by using a key, a lock button, a button, an outside door handle sensor, or by the vehicle reaching a predetermined critical speed and the like will now be described.

[0461] If the engine 1610 a lock release signal is supplied, as in figure 28 shown, the engine 1610 activates and rotates the main gear 1630 clockwise.

[0462] If the main gear 1630 is rotated clockwise, the first stopper part pushes 1633 , which is on the back surface of the main gear 1630 attached, against the main gear stopper part 1502 and move the locking plate 1500 .

[0463] At this point, the locking plate 1500 moved to the left and the first stop lever part 1450a and the second stop lever part 1450b are from the insertion space 1509 of the lever guide part 1507 separated, and the stopper projection 1455 is thereby moved forward and the stop projection 1455 is from the first locking sub-element 1400a or the second locking sub-element 1400b detected. Because of this process, the door 1 Approved; therefore, when a door handle (not shown) is pulled, a force is applied to the latch body 1300 transfer.

[0464] The first touch part 1633 moves the locking plate 1500 to the second sensor unit 1521 the locking plate 1500 from the third sensor 1905 is recognized and returns to its original state. Unlocking the door from inside the vehicle using the inside door handle

[0465] As in figure 29 is shown when the door 1 as in figure 30 is in a locked condition and the inside door handle (not shown) is pulled once, the first locking sub-member 1400a shifted to the right.

[0466] At this time, the manual lock member pressing part 1407 of the first locking sub-element 1400a shifted to the right, and at the same time the first stop part slides 1563 of the manual locking element 1560 . Due to this process, the second stop part 1562 of the manual locking element 1560 moved to the left according to the "leverage law". In addition, the second stop part moves 1562 the locking plate 1500 to the left.

[0467] While the locking plate 1500 is moved to the left becomes the first stop lever part 1450a and the second stop lever part 1450b from the insertion space 1509 of the lever guide part 1507 separated and the stop projection 1455 is by the second return spring 1460 moved forward, and the stopper projection 1455 is by the first locking sub-element 1400a and the second locking sub-element, respectively 1400b detected. Due to this operation, the locking of the door 1 raised up.

[0468] At this point, if the inside door handle (not shown) is pulled again, the latch will release 1200 from the locking part 1371 of the locking element 1300 separated and the door 1 is thereby opened. Locking the door from inside the vehicle using the child latch

[0469] When the first stop lever part 1450a from the first stop threshold 1405a is detected and the second stop lever part 1450b from the second stop threshold 1405b is detected, which is an unlocked state of the door 1 acts is the child lock tab 1453 of the first stop lever part 1450a at a distance in the left area of ​​the child locking element 1700 arranged as in figure 32 shown.

[0470] In this state, when the child lock element presses 1700 trained child lock actuating projection 1710 is shifted to the left, as in figure 33 shown, the locking projection part 1722 the child lock tab 1453 backwards.

[0471] Due to this process, the first stop lever part 1450a from the first stop threshold 1405a Cut; therefore, the first locking element 1400a not together with the main locking element 1300 postponed.

[0472] This means that when the inside door handle (not shown) is pulled, only the first locking sub-element 1400a can be moved and therefore the door can be locked from the inside.

[0473] This locked state can only be released when the child locking element 1700 is shifted to the right, and the door 1 cannot be opened from inside the vehicle when in a child-locked state, but the door can 1 be opened from the outside of the vehicle. In this way, children and elderly people can be protected against accidents caused by unexpected opening or closing of the door 1 can be caused.

[0474] Furthermore, preferably, the locking function using the child locking member from the inside of the vehicle is installed only on the rear seats of the vehicle. Opening the door in the event of an engine failure

[0475] As in figure 34 shown, the motor 1610 fail in certain situations, for example when the stop part 1631 using the engine 1610 to the door closed position for automatic door closing 1 is being moved, or during the movement, or during the time in which a return to the original position is taking place.

[0476] If the door handle is pulled in such a case, the locking element 1300 moves to the right, so that the stopper pressing arm also moves 1330 moved to the right.

[0477] Due to this operation, the stopper-pressing arm pushes 1330 against the headboard 1631a the stop part 1631 . If against the headboard 1631a is pressed, the head part 1631a farther than the ledge 1215 the trap 1200 moved backwards, so that in this way the coupling between the stopper part 1631 and the trap 1200 will be annulled.

[0478] If later, as in figure 36, the user at the door 1 pulls, turns the door catch 1101 the trap 1200 counterclockwise, and the door 1 is thereby opened.

[0479] In this way, even if the drive unit 1600 while closing the door 1 through the drive unit 1600 or after the door is closed, the door 1 opened by hand by pulling on the door handle.

[0480] When the user releases the door handle, the stop part 1621 by the return spring 1648 shifted and returned to its original position. Installation of the door locking system

[0481] The door locking system 5 will be in the central area of ​​the opposite side of the part 3installed where the door is pivotally connected to the body of the vehicle. The door locking system 5 is arranged such that the upper surface faces the inside of the vehicle and that the front surface faces the body of the vehicle and that the rear side faces the door 1 is facing. I.e. the central part of the rear surface of the door locking system 5 is arranged so that it faces the door window 2 facing when the door window 2 moves down. When the door window 2 moved downwards, this movement does not take place in a straight line but slightly obliquely. Due to this peculiarity, the central part of the left side approaches the rear surface of the door lock system 5 when moving the window down 2 the window 2 on. Thus, when the central part hits the left side of the rear surface of the door lock system 5 projecting backwards, the downward moving window 2 on this part. However, in the third exemplary embodiment of the present invention, those are on the left side of the door lock system 5 arranged main gear 1630 the gear teeth 1638 formed only in part of the right side of the outer peripheral surface, so the gear teeth 1638 can be made thick and the thickness of the left central part of the main gear 4630 can be reduced while maintaining the same resistance. Thus, mutual interference between the door window 2 and the door locking system 5 prevented when the door locking system 5 into the door 1 is installed. Assembling the door locking system

[0549] The second detent spring 4730 is formed by bending the middle part of a metal wire. Thus, the second detent spring 4730 the general shape of a hairpin open to the left . In this way, a wire-shaped spring is used as the second detent spring 4730 intended.

[0550] A first insertion part inserted into the first connector 4703 is inserted is on one side of the second detent spring 4730 educated.

[0551] A first locking part having the shape of an arc such that its upper and lower parts have the shape of the second locking projection 4108 correspond is on the right side of the first insertion part of the second detent spring 4730 educated. The second locking projection 4108 is received in the first locking part when the child locking element 4700 is in the child-lock position.

[0552] A second locking part having the shape of an arc such that its upper and lower parts have the shape of the second locking projection 4108 correspond is on the right side of the first insertion part of the second detent spring 4730 educated. The second locking projection 4108is received in the first locking part when the child locking element 4700 is in the child unlock position.

[0553] Elastically deformable parts, the widths of which are smaller than those of the first locking part and the second locking part, are between the first locking part and the second locking part 4730 educated.

[0554] A spring end portion is at the right end of the second latch portion 4730 educated.

[0555] As described above, the second detent spring has 4630 of the present exemplary embodiment has the same or a similar shape as the first detent spring of the first exemplary embodiment.

[0556] The cross section of the second locking projection 4108 has the shape of a cylinder.

[0557] Thus, to the child locking element 4700 from the child-lock release position (or to move it in the opposite direction), elastically deforming the elastically deformable portion so that the top-to-bottom width of the elastically deformable portion increases; after that, the child locking element 4700 be moved. That is, around the child lock element 4700 to move from the child-lock release position to the child-lock position, or to move the child-lock member 4700 To move from the child-lock position to the child-lock release position, the child-lock element must 4700 be displaced by a force strong enough to elastically deform the elastically deformable part of the second detent spring 4730 to deform. Locking the door from inside the vehicle using the child latch

[0558] When the driver from inside the vehicle by means of a push button and the like using the child lock member 4700 generates a door lock signal, the motor will 4610 the drive unit 4600 operated. As in figure 48(b), when the motor 4610 is operated, the main gear 4630 turned. When the main gear 4630 rotated, the main gear stopper projection 4710 from the second stop part 4635 detected and the child locking element 4700 is shifted to the right.

[0559] As in figure 49 is shown in this way when the child latch 4700 is moved, the first stop lever part 4450a through the projection guide part 4720 captured and led backwards. Due to this process, the first stop lever part 4450a separated from the first stop threshold of the first locking sub-element. The first locking sub-element and the locking main element 4300 are separated from each other and thus become the first latch sub-member and the latch main member 4300 not moved together.

[0560] In the meantime the engine is working 4610 until the third sensor unit 4741 from the eighth sensor 4902 is detected.

[0561] Thus, after the child lock is automatically activated by the drive unit 4600 has been enforced, as in figure 48© shown, the engine 4610 turned in the opposite direction so that it moves to its basic position.

[0562] Unlocking the door from inside the vehicle using the child latch

[0563] When the driver from inside the vehicle by means of a push button and the like using the child lock member 4700 generates a door lock release signal, the motor will 4610 the drive unit 4600 operated. As in figure 48(b), when the motor 4610 is operated, the main gear 4630 turned. When the main gear 4630 rotates, the main gear stopper projection becomes 4710 from the first stop part 4633 detected and the child locking element 4700 is shifted to the left.

[0564] In this way, as in figure 51 shown, when the child lock member 4700 is moved, the first stop lever part 4450a from the projection guide part 4720 separated and the right side of the first stop lever part 4450a is moved forward due to the elastic force of the second return spring. Due to this process, the first stop lever part 4450a detected by the first stop threshold of the first locking element. The first locking sub-element and the locking main element 4300 are connected to each other and thus become the first latch sub-member and the latch main member 4300 moved together.

[0565] In the meantime the engine works 4610 until the third sensor unit 4741 from the seventh sensor 4904 is detected.

[0566] Thus, after the child lock is released automatically by the drive unit 4600 has been enforced, as in figure 50(c), the engine 4610 turned in the opposite direction so that it moves to its basic position.

[0567] Since the process of rotating the latch when closing the door by the drive unit 4600 is the same as the first exemplary embodiment, its detailed description is omitted here. Fifth embodiment

[0568] In describing the door lock system according to the fifth exemplary embodiment of the present invention, the same reference numerals are used for the same or similar elements as in the door lock systems according to the first, second, third and fourth exemplary embodiments of the present invention, and the detailed description and illustration of these parts will be omitted.

[0569] As in the figure 52 bis figure 54, the door latch system according to the exemplary embodiment of the invention further includes a drive unit for driving the latch 5200 , wherein the drive unit is a motor 5610 includes and the trap 5200 through the engine 5610 is rotated; the motor 5610 and the trap 5200 are connected to each other by a spur gear.

[0616] The (bottom) end of the second electrical wire 922 is above the (lower) ends of the first electric wire 921 and the third electric wire 923 arranged.

[0617] The (bottom) ends of the first electrical wire 921 and the third electric wire 923 are spaced from each other in the horizontal direction (left-right direction); this is the direction in which the locking plate 6500 is postponed.

[0618] If the locking plate 6500 is moved, the electrical connection element connects 6572 the first and second electric wires 921 and 922 or it connects the second and third electrical wires 922 and 923 .

[0619] The operations of the door lock system having the configuration described above and according to the sixth exemplary embodiment of the present invention will be described below. closing the door

[0620] When the user closes the open door, pushes the door latch installed on the vehicle body 1101 against the trap 6200 , causing the trap 6200 is rotated clockwise.

[0621] The locking part of the rotating element 6370 is inserted into the locking recess of the latch 6200 inserted and the door is hereby closed. locking the door

[0622] The process of changing the unlocked state of the door to the locked state by using a key, a lock knob, a button, an outside door handle sensor, or by the vehicle reaching a predetermined critical speed and the like will now be described.

[0623] If the engine 6610 a lock signal is supplied, the motor operates 6610 and turns the main gear 6630 counterclockwise.

[0624] If the main gear 6630 is rotated counterclockwise, the second stopper part pushes 6635against the main gear stopper 6502 the locking plate 6500 and move the locking plate 6500 .

[0625] If the locking plate 6500 is moved to the right, the stopper lever unit comes out 6450 from the stop threshold of the locking sub-element and the connection between the locking main element 6300 and the locking sub-element is released. Due to this action, the door goes into the latched state and thus when the door handle (not shown) is pulled, the force is not applied to the latch body 6300 transfer.

[0626] The motor 6610 works until that on the locking plate 6500 installed electrical connector 6572 the second electrical wire 922 and the third electric wire 923 connects with each other. Then the engine stops 6610 to work.

[0627] If the main gear 6630 rotated counterclockwise pushes the sliding rib 6140 against the gear return spring 6650 causing the gear return spring 6650 is compressed. If the the main gear 6630 turning power is removed (when the engine is working 6610 stops) due to the restoring force of the compressed gear return spring 6650 the main gear 6630 returned to its original position. unlocking the door

[0628] The process of changing the locked state of the door to the unlocked state by using a key, a lock button, a button, an outside door handle sensor, or by the vehicle reaching a predetermined critical speed and the like will now be described.

[0629] If the engine 6610 a door unlock signal is supplied, the engine starts 6610 to work and rotates the main gear 6630 clockwise.

[0630] If the main gear 6630 is rotated clockwise, the first stopper part pushes 6633 against the main gear stopper 6502 the locking plate 6500 and move the locking plate 6500 .

[0631] In this case, the locking plate 6500 shifted to the left and the stopper lever unit 6450 is detected by the abutment threshold of the locking sub-element, thereby locking the main element 6300 and the locking sub-element are connected to each other. Due to this operation, the door enters the unlocked state and therefore the force generated when the door handle is pulled is applied to the lock main element 6300 transfer.

[0632] The motor 6610 works until that on the locking plate 6500 installed electrical connector the second electrical wire 922 and the first electric wire 921 connects with each other. Then the engine stops 6610 to work.

[0633] If the main gear 6630 rotated clockwise pushes the sliding rib 6140 against the gear return spring 6650 and the gear return spring 6650 is thereby compressed. If the the main gear 6630 turning force is absent (when the engine is working 6610 stops), becomes the main gear 6630 due to the restoring force of the compressed gear return spring 6650 returned to its original position. opening the door

[0634] When the door is in an unlocked state and the user pulls the door handle, the door handle connection unit pulls the latch sub-member and the latch main member 6300 To the right. Due to this process, the locking part of the rotating element 6370 from the locking receptacle of the latch 6200 Approved. At this point, the trap reverses 6200 return to the original position due to the action of the first return spring. Thus, the door catch 1101released by the door locking system.

[0635] Since the operation of locking the door from the inside of the vehicle using the child lock member and the operation of unlocking the door from the inside using the inside door handle are the same as described in connection with the first exemplary embodiment, the description of these operations will be described omitted here.

[0640] The process of changing the unlocked state of the door to the locked state by using a key, a lock knob, a button, an outside door handle sensor, or by the vehicle reaching a predetermined critical speed and the like will now be described.

[0641] If the engine 7610 a lock signal is supplied, the motor operates 7610 and turns the main gear 7630 counterclockwise.

[0642] If the main gear 7630 is rotated counterclockwise, the second stopper part presses against the main gear stopper part 7502 and the locking plate is moved.

[0643] When the lock plate is moved to the right, the stopper lever unit disengages from the stopper sill of the lock sub member, and the connection between the lock main member and the lock sub member is released. Due to this operation, the door goes into the latched state and thus when the door handle (not shown) is pulled, the force is not transmitted to the latch body.

[0644] The motor 7610 works until the electrical connector installed on the locking plate connects the second electrical wire and the third electrical wire. Then the engine stops 7610 to work. unlocking the door

[0645] The process of changing the locked state of the door to the unlocked state by using a key, a lock knob, a button, an outside door handle sensor, or by the vehicle reaching a predetermined critical speed and the like will now be described.

[0646] If the engine 7610 a door unlock signal is supplied, the engine starts 7610 to work and rotates the main gear 7630 clockwise.

[0647] If the main gear 7630 is rotated clockwise, the first stopper part presses against the main gear stopper part 7502 and move the locking plate.

[0648] At this time, the lock plate is shifted to the left, and the stopper lever unit is caught by the stopper sill of the lock sub, thereby connecting the lock main and the lock sub. Due to this operation, the door enters the unlocked state and therefore the force generated when the door handle is pulled is applied to the lock main element 6300 transfer.

[0649] The motor 7610 works until the electrical connector installed on the locking plate connects the second electrical wire and the first electrical wire. Then the engine stops 7610 to work. Eighth embodiment
