  An accommodation groove 105 is formed in a portion of the latch housing 102 corresponding to the striker of the vehicle main body B, specifically, at an end of the latch housing 102. The housing groove 105 is a groove-shaped notch extending leftward from the right end of the latch housing body 102 in FIG. 1. When the door D is closed with respect to the vehicle body B, the striker S is formed. It is formed in the position and the size which can accommodate. The back plate 103 is also formed with a second receiving groove 106 that matches the receiving groove 105 and can receive the striker when the door D is closed with respect to the vehicle body B.

  The main body 101a and the latch housing 102 are provided with a latch shaft 125 and a ratchet shaft 126 at the upper and lower portions with the housing groove 105 interposed therebetween. The latch shaft 125 is for rotatably supporting the latch 122 with respect to the main body 101 a and the latch housing 102, and is provided in the vicinity of the back end of the housing groove 105. The ratchet shaft 126 is for rotatably supporting the ratchet 123 with respect to the main body 101a and the latch housing 102, and is provided in the vicinity of the opening end of the housing groove 105.

  As shown in FIG. 1, the ratchet 123 extends from the ratchet shaft 126 toward the rear end portion of the receiving groove 105, and has a latch locking portion 231 inside the latch receiving body 102. As shown in FIGS. 1 and 4, there is a ratchet coupling portion 232 that extends outside the latch housing 102 and extends to the surface side of the main body portion 101 a of the base plate 101.

  As shown in FIG. 1, the latch locking portion 231 is a convex portion projecting from the side surface of the ratchet 123 toward the housing groove 105 in the vicinity of the back end portion of the housing groove 105.

  The ratchet coupling portion 232 has a portion extending from the ratchet shaft 126 toward the opening end portion of the receiving groove 105. As shown in FIG. 4, the ratchet connecting portion 232 includes a ratchet release lever 233 at a portion on the surface side of the main body portion 101 a.

  The engagement groove 221 is a notch formed from the outer peripheral surface of the latch 122 toward the direction close to the latch shaft 125, and has a width capable of accommodating the striker. When the latch 122 is rotated clockwise about the latch shaft 125 as shown in FIG. 16, the meshing groove 221 sequentially intersects from the opening end to the back end of the receiving groove 105. It is constituted as follows.

  The hook portion 222 is a portion located on the opening end side of the housing groove 105 when the meshing groove 221 intersects the housing groove 105.

  When the engaging portion 223 comes into contact with the latch engaging portion 231 of the ratchet 123, the engaging portion 223 restricts the counterclockwise rotation of the latch 122 in FIG. As shown in FIG. 17, the engaging portion 223 is configured such that the hook portion 222 of the latch 122 is positioned at the opening end portion of the receiving groove 105 when contacting the latch engaging portion 231. When the latch locking portion 231 comes into contact with the engaging portion 223, the hook portion 222 protrudes to a position where the striker can be prevented from passing through the housing groove 105.

  When the door D is in an open state with respect to the vehicle body B, the latch 122 and the ratchet 123 are arranged in the open position as shown in FIG. 16 (open state). When the closing operation of the door D is started from this state, the striker S enters the receiving groove 105, and the latch 122 rotates clockwise in FIG. 16 against the elastic force of the latch spring. During this time, the ratchet 123 has the protruding end surface of the engaging portion 223 slidably contacted with the outer peripheral surface of the latch 122 by the elastic force of the ratchet spring, and appropriately rotates around the axis of the ratchet shaft 126 according to the outer peripheral surface shape of the latch 122.

  When the door D is further closed from the above-described state, the amount of the striker S entering the receiving groove 105 gradually increases, so that the latch 122 further rotates clockwise, and eventually, as shown in FIG. The locking portion 231 reaches the meshing groove 221 of the latch 122. In this state, the engaging portion 223 of the latch 122 comes into contact with the latch engaging portion 231 of the ratchet 123, so that the counterclockwise rotation of the latch 122 is prevented. Moreover, since the hook portion 222 of the latch 122 is arranged so as to cross the housing groove 105, the situation in which the striker S moves away from the housing groove 105 by the hook portion 222, that is, the door D is opened with respect to the vehicle body B. Will be blocked (half-latched state).

  When the door D is further closed from the half-latched state, the latch 122 further rotates counterclockwise by the striker S entering the accommodation groove 105, and the striker S reaches the rear end (outdoor) of the accommodation groove 105. . During this time, the ratchet 123 rotates counterclockwise against the elastic force of the ratchet spring by the hook portion 222 of the latch 122 coming into contact with the latch engaging portion 231, and when the hook portion 222 of the latch 122 passes. The ratchet spring will immediately rotate clockwise due to the elastic restoring force. As a result, as shown in FIG. 17, the hook portion 222 of the latch 122 comes into contact with the latch engaging portion 231 of the ratchet 123, so that the counterclockwise rotation of the latch 122 is prevented. Even in this state, since the hook portion 222 of the latch 122 is arranged so as to cross the receiving groove 105, the hook portion 222 prevents the striker S from moving away from the receiving groove 105. D is kept closed with respect to the vehicle body B (full latch state).

  When the ratchet connecting portion 232 of the ratchet 123 is rotated counterclockwise in FIG. 18 against the elastic force of the ratchet spring from the fully latched state, the contact between the hook portion 222 of the latch 122 and the latch engaging portion 231 of the ratchet 123 The contact engagement state is released, and the latch 122 rotates counterclockwise in FIG. 18 by the elastic restoring force of the latch spring. As a result, as shown in FIG. 16, the accommodation groove 105 is opened, the striker S can be moved in a direction away from the accommodation groove 105, and the door D can be opened with respect to the vehicle body B. .

It is a part connected to the sill knob linkage lever 160. The ratchet pressing portion 173 is a portion that extends from an intermediate portion between the open lever linkage portion 171 and the sill knob lever linkage portion 172 toward the vehicle interior side. The tip of the ratchet pressing portion 173 is bent so as to be close to the surface of the main body 101 a of the base plate 101. The ratchet pressing portion 173 faces the ratchet pressure receiving portion 234 of the ratchet 123 when the link lever 170 is moved to the lock position as will be described later.

  19 to 22 are conceptual diagrams showing a case where the lock unit 100 is operated. Hereinafter, the operation of the lock unit 100 will be described with reference to these drawings.

  Here, for convenience of explanation, the door D is in a closed state, and as shown in FIG. 19, the open lever 130 is disposed at the initial position by the elastic force of the open lever spring 134, and the link is opened by the open lever 130. The lever 170 is disposed at the initial position where it is moved upward, the sill knob linking lever 160 is disposed at the initial position rotated most counterclockwise in FIG. 19, and the key lever 150 is disposed in the key linking portion 151 in FIG. It is assumed that the fifth arm linkage rod portion 152 is disposed at the initial position where it is substantially horizontal, and the lock unit 100 is in the unlocked state by arranging the levers 130, 150, 160, 170 in this way. To do.

  In this state, as is apparent from the drawing, the ratchet pressure receiving portion 234 of the ratchet 123 and the ratchet pressing portion 173 of the link lever 170 face each other. In this state, for example, when the outside handle 10 is operated, the open lever 130 rotates clockwise in FIG. 19 via the fourth linkage member 174, and the link lever 170 is moved downward by the rotation of the open lever 130. Will be moved to.

  At this time, as the link lever 170 moves downward, the ratchet pressing portion 173 of the link lever 170 presses the ratchet pressure receiving portion 234 of the ratchet 123, and the ratchet release lever 233 rotates clockwise in FIG. The contact engagement state between the hook portion 222 of the latch 122 and the latch locking portion 231 of the ratchet 123 is released. Therefore, even when the door D is in the closed state, the door D can be moved to open by pulling the outside handle 10 to the outside of the vehicle.

  Further, when the inside handle is operated from the initial state shown in FIG. 19, the inside handle lever 140 rotates counterclockwise in FIG. 3 via the second linkage member, and the inside handle lever 140 rotates. Accordingly, the inside handle pressing portion 142 of the inside handle lever 140 presses the handle pressure receiving portion 131 of the open lever 130, and the open lever 130 rotates clockwise in FIG.

  Then, as in the case of operating the outside handle 10 described above, the link lever 170 moves downward, and the ratchet release lever 233 rotates clockwise in FIG. 19, and the hook portion 222 of the latch 122 and the ratchet 123, the contact engagement state with the latch locking portion 231 is released, and even when the door D is in the closed state, the door D is opened by pressing the inside handle to the outside of the vehicle. It can be moved.

  Further, when the sill knob 9 is operated from the initial state shown in FIG. 19, the second arm member 75 is rotated counterclockwise in FIG. 7 around the axis of the second shaft member 60 via the first linkage member. As the second arm member 75 rotates, the third arm member 77 also rotates counterclockwise. Then, the counterclockwise rotation of the third arm member 77 causes the sill knob linking lever 160 to rotate counterclockwise as shown in FIG. Due to the counterclockwise rotation of the sill knob linkage lever 160, the link lever 170 is pivoted clockwise around the first connection point 178 and the sill knob lever linkage portion 172 is pivoted at the tip of the rotation. Will move to the locked position. When the link lever 170 moves to the lock position in this way, the ratchet pressure receiving portion 234 of the ratchet 123 and the ratchet pressing portion 173 of the link lever 170 do not face each other.

  In this state, when the outside handle 10 is operated or the inside handle is operated, the downward movement of the link lever 170 is not transmitted to the ratchet pressure receiving portion 234 of the ratchet 123, as shown in FIG. That is, the ratchet pressing portion 173 of the link lever 170 does not contact the ratchet pressure receiving portion 234 of the ratchet 123, and the contact engagement state between the hook portion 222 of the latch 122 and the latch locking portion 231 of the ratchet 123 is maintained. It will not be released. Therefore, when the door D is in the closed state, the door D cannot be moved to open even if the outside handle 10 is pulled outside the vehicle, and the inside handle is pushed to the outside of the vehicle. Even so, the door D cannot be moved open. If the sill knob 9 is operated in reverse from this state, the link lever 170 moves from the locked position to the unlocked position, and the operation of the outside handle 10 and the operation of the inside handle are validated.

  Further, from the initial state shown in FIG. 19, the electric motor 40 shown in FIG. 7 is driven by operating a switch provided in the driver's seat or by operating a switch provided in the key. 7, when the worm wheel 44 is rotated clockwise in FIG. 7, the first wheel tooth piece 44 a of the worm wheel 44 and the first arm member 70 of the first arm member 70 are rotated along with the clockwise rotation of the worm wheel 44. In contact with the lever tooth piece 71, the first shaft member 50 rotates counterclockwise in FIG. 7, and the third arm member 77 also rotates counterclockwise as the first arm member 70 rotates. It will be. Then, as in the case where the sill knob 9 is operated, the sill knob linkage lever 160 rotates counterclockwise so that the ratchet pressure receiving portion 234 of the ratchet 123 and the ratchet pressing portion 173 of the link lever 170 do not face each other. The link lever 170 rotates about the first connection point 178, and the link lever 170 is disposed at the lock position.

  In this state, even if the outside handle 10 is operated or the inside handle is operated, the movement of the link lever 170 is not transmitted to the ratchet pressure receiving portion 234 of the ratchet 123, and the hook portion 222 of the latch 122, The contact engagement state of the ratchet 123 with the latch locking portion 231 is not released. Therefore, when the door D is in the closed state, the door D cannot be moved to open even if the outside handle 10 is pulled outside the vehicle, and the inside handle is pushed to the outside of the vehicle. Even so, the door D cannot be moved open. If the electric motor 40 is reversely driven from this state, the link lever 170 moves from the locked position to the unlocked position, and the operation of the outside handle 10 and the operation of the inside handle are validated.

  When the key is inserted into the key cylinder 11 and the key cylinder 11 is rotated from the initial state shown in FIG. 19, the key lever 150 is rotated counterclockwise via the third linkage member 153 as shown in FIG. Will be rotated. As the key lever 150 rotates counterclockwise, the link lever 170 rotates about the first connection point 178 and the sill knob lever linkage 172 rotates clockwise with the rotation tip, and the link lever 170 is locked. Will be moved to. When the link lever 170 moves to the lock position in this way, the ratchet pressure receiving portion 234 of the ratchet 123 and the ratchet pressing portion 173 of the link lever 170 do not face each other.

  In this state, even if the outside handle 10 is operated or the inside handle is operated, the downward movement of the link lever 170 is not transmitted to the ratchet pressure receiving portion 234 of the ratchet 123. The ratchet pressing portion 173 does not contact the ratchet pressure receiving portion 234 of the ratchet 123, and the contact engagement state between the hook portion 222 of the latch 122 and the latch locking portion 231 of the ratchet 123 is not released. . Therefore, when the door D is in the closed state, the door D cannot be moved to open even if the outside handle 10 is pulled outside the vehicle, and the inside handle is pushed to the outside of the vehicle. Even so, the door D cannot be moved open. If the key cylinder 11 is rotated in reverse from this state, the link lever 170 moves from the locked position to the unlocked position, and the operation of the outside handle 10 and the operation of the inside handle are validated.

Here, for convenience of explanation, as shown in FIG. 28, the child connection lever 300 is disposed at the lock position so that the inside handle lever shaft 109 is positioned below the shaft connection hole 301, and the fifth connection pin 307 is provided. However, the child lock lever 310 is in the lock position so that the fifth connecting pin 307 is located at the end of the pin operating groove 312 close to the child lock lever shaft 310a. It is explained as a thing.

In this state, the fourth connecting pin 306 of the child connecting lever 300 is occupied outside the rotational movement region of the pin pressing portion 144 of the inside handle lever 140 ′. In this state, by operating the inside handle, the inside handle lever 140 'is also rotated counterclockwise in FIG. 28, without the pin pressing portion 144 comes into contact with the fourth coupling pin 306 The contact and joining state between the hook portion 222 of the latch 122 and the latch engaging portion 231 of the ratchet 123 is not released via the open lever 130 and the link lever 170. Therefore, when the door D is in the closed state, the door D cannot be moved to open even if the inside handle is pressed to the outside of the vehicle.

  Next, by operating the switching operation portion 315 from the locked state described above, the child lock lever 310 is locked so that the fifth connecting pin 307 is positioned below the first lock long hole 29a as shown in FIG. Switch from position to unlock position.

In this state, the fourth connection pin 306 of the child connection lever 300 is occupied within the rotational movement region of the pin pressing portion 144 of the inside handle lever 140 ′. In this state, by operating the inside handle, the inside handle lever 140 'is rotated counterclockwise in FIG. 29, as shown in FIG. 30, the pin pressing part 144 to the fourth coupling pin 306 The fifth connecting pin 307 comes into contact with the other end of the second lock long hole 29b that is separated from the inside handle lever shaft 109 from the one end close to the inside handle lever shaft 109. The second inside handle pressing portion 303 of the child connecting lever 300 abuts on the handle pressure receiving portion 131 of the open lever 130, and the latch 122 is moved through the rotation of the open lever 130 and the movement of the link lever 170 as described above. Hook portion 222 and latch latching portion 231 of ratchet 123 So that the abutment joint state is canceled. Therefore, even when the door D is in the closed state, the door D can be moved to open by pressing the inside handle to the outside of the vehicle.
