Description

TECHNICAL APPLICATION

The present invention relates to a door lock device.

STATE OF THE ART

The door lock device includes a fork for releasably holding a striker, a pawl lever for locking the fork that holds the striker, and a power driven gear member for releasing the locking of the fork by the pawl lever.

At the door lock of the JP 2011-94346 A For example, a fork, a claw lever, and a gear member are disposed on the same surface. In this door locking device, the rotationally driven transmission element directly actuates the claw lever.

In the door lock device of JP 2013-14929 A For example, a fork and a jaw lever are held on a first plate and a gear member is held on a second plate which crosses the first plate. Moreover, the door lock device includes an opening lever that allows the door to be opened by manual operation when the door can not be electrically opened when the power supply is cut off by the battery or the like.

The rotationally driven transmission element actuates the claw lever through the opening lever. In addition, when the opening lever is operated directly from the opening portion provided in the inner panel on the inside of the vehicle constituting the door, the opening lever operates the jaw lever.

SUMMARY OF THE INVENTION

PROBLEMS TO BE SOLVED BY THE INVENTION

In the door lock apparatus of Patent Literature 1, since the fork, the claw lever and the gear member are arranged on the same surface, it is necessary to ensure a wide arrangement area. Therefore, this door lock has large dimensions, and miniaturization is not considered.

Since the fork and the claw lever and the gear member are three-dimensionally arranged on different plates, it is possible in the door lock of Patent Literature 2 to miniaturize the door lock compared to the door lock of Patent Literature 1. However, this door lock still has room for further miniaturization.

The aim of the present invention is to miniaturize a door locking device.

MEANS TO SOLVE THE PROBLEMS

One aspect of the present invention provides a door lock apparatus including: a fork configured to rotate to a holding position for holding a striker in a non-releasable manner and a release position for releasing the striker; a jaw lever configured to rotate about a first rotary shaft to a locking position for locking the fork in the holding position, and to rotate to a non-locking position for releasing the lock with the fork to allow the fork to move to the release position rotate; and a rotating element including a second rotation shaft configured to cross the first rotation shaft. The rotating member includes an operating portion projecting toward the jaw lever. The claw lever includes an operation receiving section configured to receive an operation of the operation section. The rotary member is configured to rotate about the second rotary shaft from a first position in which the operating portion is separated from the operation receiving portion, to a second position in which the operating portion abuts the operation receiving portion. The operation receiving portion includes an inclined portion configured to be inclined in one direction away from the operating portion of the rotary member in the first position, in a direction opposite to a direction in which the jaw lever moves from the lock position to the first position Non-locking position rotates about the first rotation shaft, wherein the inclined portion is configured to abut the operating portion of the rotating member in the second position. The rotating member rotated from the first position beyond the second position causes the operating portion to press the inclined portion of the operation receiving portion to rotate the jaw lever to the non-locking position.

According to this aspect, since the jaw lever and the rotary member are three-dimensionally arranged on different surfaces, the operating portion of the rotary member abuts the inclined portion of the operation receiving portion in an intersecting manner. Then For example, the rotation of the rotating member - which causes the operating portion to press the inclined portion - causes the inclination of the inclined portion to rotate the jaw lever from the lock position toward the non-lock position.

Since the jaw lever and the rotating member are three-dimensionally arranged on different surfaces, the arrangement surfaces for the fork and the jaw lever can be set to save space and the entire apparatus can be miniaturized. In addition, since the rotating member directly operates the jaw lever, it is not necessary to secure a space for locating a part of the opening lever between the jaw lever and the rotating member. Since these components can be arranged together, the entire device can also be miniaturized in this respect.

EFFECT OF THE INVENTION

In the door lock device of the present invention, since the jaw lever and the rotary member are three-dimensionally arranged on different surfaces and the jaw lever is operated directly by the rotary member, each of the components can be disposed in common, and the entire apparatus can be miniaturized.

The opening operation receiving section 48 is integral with the stop block 14 arranged claw lever 26 formed, and the closing operation receiving section 50 is integral with the stop block 14 arranged fork 22 educated.

In the electric opening / closing mechanism 32 actuates the dental arch 41 , an operating section 44 including, by an electric motor 35 which is driven to be opened by the ECU, the opening operation receiving section 48 and turns the claw lever 26 from the lock position to the unlocked position. This will cause the fork 22 turned to the open position and the locking mechanism 20 is brought into the open state. In addition, the dental arch actuates 41 with the operating section 44 in the electric opening / closing mechanism 32 through the electric motor 35 which is driven to be closed by the ECU, the closing operation receiving section 50 , turns the fork 22 in the position of full locking and offset the locking mechanism 20 in a locked state. The following is the configuration of the electric opening / closing mechanism 32 described in more detail.

The actuator 34 closes the electric motor 35 which is capable of performing a normal rotation (opening drive) and a reverse rotation (closing drive), and an output gear 36 that mechanically with the output shaft of the electric motor 35 connected is. The electric motor 35 is on the surface on the side of the outer wall 5 the base plate 13 attached. The output gear 36 is on the surface on the side of the inner wall 7 the base plate 13 through the penetrating section 13 b of the base plate 13 arranged.

By connecting a connector 38 that has an electrical line 37 with a connector (not shown) of the back door 4 is connected, the electric motor 35 electrically connected to the ECU and the battery. To the connector 38 are also a switch 21 , shown in 7 B , a fork switch 25 , shown in 2 , and a switch 39 , shown in 2 , electrically connected. By switching on through the claw lever 26 the switch detects 21 that the claw lever 26 turns to the unlocked position. The hook switch 25 is a rotary switch with a sensor (not shown), and through the sensor - which is on a section of the fork 22 rests, which should be pressed together with the fork 22 to be connected - recognizes the hookswitch 25 in which from the open position, the position of the half-lock and the position of the complete locking yourself the fork 22 emotional. By the switch 39 through a disruptive element 43 of the dental arch 41 turned on, this detects that the dental arch 41 turns into the neutral position.

The dental arch 41 is a roughly fan-shaped plate body, on the side of the inner wall 7 the base plate 13 is arranged. The dental arch 41 is by a rotation shaft (second rotation shaft) 42 pivotally mounted in a through hole 13 c (see 3 ) of the base plate 13 is arranged.

It should be noted that the specific configuration of the operating section 44 will be described in detail below.

The dental arch 41 starts in the in the 7 A and 12 A shown neutral position, the normal rotation of the electric motor 35 causes the dental arch 41 through the output gear 36 is rotated counterclockwise (first direction), and the reverse rotation of the electric motor 35 causes the dental arch 41 through the output gear 36 is rotated clockwise (second direction). That is, as in 4 shown, the dental arch 41 is rotated so that a circular arc A about the rotation shaft 42 is pulled.

As in 7 A is shown, the operating section 44 in the neutral position (first position) of the opening operation receiving section 48 of the claw lever 26 arranged separately in the locking position. The dental arch passes through the opening drive 41 the rotational angular position (second position) in which the operating portion 44 on the opening operation receiving section 48 is present, as in 8 A and rotates to the rotational angular position (third position) in which the opening operation receiving section 48 through the operating section 44 is pressed, as in 10 A shown. The dental arch passes through the closing drive 41 the rotational angle position in which the actuating portion 44 on the closing operation receiving section 50 rests, and rotates in the rotational angular position in which the closing operation receiving section 50 through the operating section 44 is pressed.

As in the 4 and 5 shown, by receiving an operation by the operating section 44 the opening operation receiving section 48 the claw lever 26 in the direction B, in which the lock between the fork 22 and the claw lever 26 is released, and is integral with the jaw lever 26 educated. The opening operation receiving section 48 protrudes from the gap between the base plate 13 and the locking lid 16 in the direction of the operating section 44 out. With reference to 7 A is in a state in which the jaw lever 26 in the lock position, the opening operation receiving section 48 in the lower part (direction A 1, moved by the opening operation) and on the left side (the outer side of the circular arc path A of the operating portion 44 ) of the operating section 44 positioned. It should be noted that the specific structure of the opening operation receiving section 48 will be described in detail below.

As in the 2 and 4 As shown, the closing operation receiving section rotates 50 the fork 22 upon receipt of an operation by the operation section 44 in one direction of rotation to the position of full locking and is integral with the fork 22 intended. The closing operation receiving section 50 includes a mounting portion 50 a, which is formed to be bent, and the attachment portion 50 a is at the top of the rotary shaft 23 attached to the latch cover 16 in the direction of the operating section 44 protrudes. The closing operation receiving section 50 extends along the rotation shaft 23 and is circular arc around the rotary shaft 23 trained around. With reference to the 12 A and 12 B is in a state where the fork is 22 in the open position, the closing operation receiving section 50 on the right side of the operating section 44 positioned and to the operating section 44 curved down.

(Description of the manual opening mechanism)

The manual opening mechanism 52 includes an opening lever 54 with an opening operation section 54 c and the opening operation receiving section described above 48 , That is, the opening operation receiving section 48 The present embodiment is configured to control both the operation by the operating portion 44 the electric opening / closing mechanism 32 as well as the operation by the Öffnungsbetätigungsabschnitt 54 c of the manual opening mechanism 52 to recieve.

The opening lever 54 closes a shaft section 54 a, which is rotatable on a mounting hole 13 d (see 3 ) of the base plate 13 is attached. In addition, the opening lever includes 54 a grip section 54 b and an opening operation section 54 c, with the shaft section 54 a protrude as a center. The grip section 54 b is in the locking mechanism 20 opposite direction. An opening (not shown), such as a slot, is in a portion of the inner wall 7 opposite the handle section 54 b provided to the handle portion 54 b to operate from a vehicle interior with a tool or the like. The opening operation section 54 c turns the jaw lever 26 by operating the opening operation receiving section 48 and is toward the opening operation receiving section 48 out. The opening lever 54 is by a spring 55 biased from the operating position, in which the jaw lever 26 is actuated to operate by the operation of the opening operation receiving section 48 in the direction of the non-operation position, from the opening operation receiving section 48 removing, being opened.

(Details of the operating section)

As in the 4 and 5 illustrated, the operating section closes 44 a first pen 45 a, which has a substantially rectangular columnar shape with a rounded corner portion, and a second pin 46 , which has a cylindrical shape, and is the jaw lever 26 out. By the rotation of the dental arch 41 These rotate around a circular arc A about the rotation shaft 42 to draw.

If the dental arch 41 by the normal rotation of the electric motor 35 is driven to open, the first pin rotates 45 in the direction A 1, in which the first pin 45 on the opening operation receiving section 48 is applied. This will push the first pen 45 the opening operation receiving section 48 , and the claw lever 26 rotates against the biasing force of the spring 30 from the lock position to the unlocked position (direction B). In addition, if the dental arch 41 by the reverse rotation of the electric motor 35 is brought to close, the first pin rotates 45 in the direction A 2, in which the first pin 45 on the closing operation receiving section 50 is applied. This causes the first pin 45 the closing operation receiving section 50 pushes and that the fork 22 itself - against the biasing force of the spring 24 - Turn from the side of the open position (half the lock position) to the position of the full lock.

The second pen 46 is from the first pen 45 in a direction away from the rotation shaft 42 (from the dental arch 41 spaced radially outward). After the dental arch 41 by the normal rotation of the electric motor 35 is driven to open and the first pin 45 the opening operation receiving section 48 pressed, pushes the second pin 46 on. In other words, the second pen 46 encounters the opening operation receiving section 48 , where the claw lever 26 at a predetermined angle around the first pin 45 is rotated, and causes the jaw lever 26 in the direction of the non-locking position, the first pin 45 following. It should be noted that the second pen 46 the closing operation receiving section 50 not activated.

As described above, in the present embodiment, the first pin 45 and the second pen 46 configured to the opening operation receiving section 48 through the opening drive of the dental arch 41 operate sequentially. Since the rotation angle (operating stroke) of the jaw lever 26 can be sufficiently secured, thus, the shape of the opening operation receiving section 48 be downsized.

(Details of the opening operation receiving section)

As in 5 shown is the jaw lever 26 a jaw assembly having a lever main body 27 metal and the opening operation receiving section 48 made of resin (eg polyacetal).

The outer peripheral portion of the lever main body 27 is with a cover material 28 made of resin (eg elastomer). The locking section 27 a is in the lever main body 27 trained and stands by the cover material 28 out. The lever main body 27 is with an arm section 27 b provided along the rotation shaft 29 in the direction of the operating section 44 protrudes. The arm section 27 b stands for the cover material 28 out. The arm section 27b is with a sloped section 27 c equipped, the inclined section 48 c of the opening operation receiving section 48 equivalent.

The opening operation receiving section 48 is with a mounting hole 48 a provided to at the top of the arm section 27 b to be mounted. The mounting hole 48 a is with a locking portion 48 b equipped with a locking step section 27 d to lock, which in the arm section 27 b is formed. The opening operation receiving section 48 closes the inclined section 48 c, on which the operating section 44 of the dental arch 41 rests, and an adjacent section 48 d, on which the opening operation section 54 c of the opening lever 54 rests.

With reference also to 6 A , is the inclined section 48 c inclined in one direction, away from the operating section 44 of the rotating element 41 Removing in the neutral position, in the direction of the side, opposite to the direction B, in which the jaw lever 26 during the opening process turns. That is, the inclined section 48 c extends in a tangential direction with respect to a circumferential circular arc path, in which the jaw lever 26 rotates, and is inclined in the direction A 1 down, in which the actuating portion 44 is driven to open in the direction in which the spring 30 the claw lever 26 biases. Thus, the first pin meet 45 and the second pen 46 from the top of the inclined section 48 c, in an attitude in which the first pen 45 and the second pen 46 to cross each other. In addition, the claw lever can 26 by the inclination of the inclined section 48 c are rotated to the unlocked position by the first pin 45 and the second pen 46 the inclined section 48 Press c down.

When the inclination angle of the inclined section 48 c (the angle passing through the top of the lever main body 27 and the inclined section 48 c is formed) is too small, the rotation of the jaw lever 26 complicates and the opening operation receiving section 48 becomes big. On the other hand, is the inclination angle of the inclined portion 48 c too steep, becomes the operating stroke of the jaw lever 26 shortened. About the opening operation receiving section 48 to miniaturize, therefore, the inclination angle of the inclined portion 48 c is preferably set to 45 degrees or more and 45 degrees in the present embodiment. Because the actual release angle of the jaw lever 26 (the angle at which the latch between the fork 22 and the claw lever 26 dissolved) is about 20 degrees and the full stroke (angle at which the jaw lever 26 can turn mechanically) is about 30 degrees, the operating rotation angle of the jaw lever becomes 26 preferably set to 20 degrees to and including 30 degrees inclusive by electric operation, and in the present embodiment, the operation rotation angle is set to 25 degrees.

As in 6 B shown when the width W of the inclined portion 48 c from the radial inside to the outside of the jaw lever 26 is too large, it is necessary to increase the distance between the base plate 13 and the locking lid 16 to enlarge. When the width W of the inclined portion 48 c is too small - unless the total length of the first pin 45 and the second pin 46 not enlarged - can be the first pen 45 or the second pen 46 not be kept in a state in which he is at the inclined section 48 c is applied until the jaw lever 26 is rotated to the unlocked position. On the other hand, the arm portion 27 b of the claw lever 26 by bending a part of the lever main body 27 , which is made of metal, approximately at right angles along the rotational shaft direction of the jaw lever 26 achieved, and in the present embodiment, since the plate thickness of the lever main body 27 is set to 5 mm, is also the width of the arm section 27b set to 5 mm. When the arm section 27 b with the opening operation receiving section 48 is covered, the width W of the inclined portion 48 c is widened to 8 mm, and it is secured sufficient tolerance for the collision of components, so that the first pin 45 or the second pen 46 on the inclined section 48 c rests.

Subsequently, referring to 6 B the inclined section 48 c formed in a curved surface shape, which leads to the pins 45 and 46 along the direction in which the first pin 45 and the second pen 46 extend, protrudes. That is, the cross-sectional shape of the inclined portion 48 c in the direction of the width W is curved upward. Thus take the first pen 45 and the second pen 46 Point contact with the inclined section 48 c on. This allows the inclined section 48 c and the pins 45 and 46 The friction resistance is reduced during operation by the state of a smooth sliding friction and the jaw lever 26 can by driving the dental arch 41 be reliably rotated. The radius of curvature r of the inclined portion 48 c is preferably set so that the moving distance of the floating point with respect to the width W of the inclined portion 48 c ½ W or more, so that the glide path of the operating section 44 and the inclined section 48 c from one end face to the other end side in the width direction of the inclined portion 48 c, ie, that the sliding distance is increased when the jaw lever 26 is rotated from the locking position to the non-locking position, and in the present embodiment, the radius of curvature r is set to 10 mm. With this configuration, the floating point is changed to a state of more light sliding friction, and the sliding resistance between the operation section 44 and the inclined section 48 c as well as the wear of the inclined section 48 c be reduced.

Thus, by providing the opening operation receiving section 48 at the top of the arm section 27 b of the claw lever 26 the opening operation receiving section 48 near the operating section 44 be arranged so that the degree of freedom in the arrangement of the dental arch 41 can be increased. Since the opening operation receiving section 48 is a resin component, it is possible to reduce the collision noise when the operating portion 44 on the opening operation receiving section 48 rests, and to reduce the operating noise when the operating section 44 with the inclined section 48 c slidably comes in contact.

With reference to 7 A along with 6 B , is the inclined section 48 c - seen from the direction of direct alignment with the dental arch 41 - At the same height as the rotary shaft 42 of the dental arch 41 arranged. That is, the inclined section 48 c of the opening operation receiving section 48 , and the rotation shaft 42 of the dental arch 41 are arranged at a distance right and left and adjusted so that the distances from the locking lid 16 are essentially the same. In other words, the inclined section 48 c and the rotation shaft 42 of the dental arch 41 are in a direction orthogonal to the direction of extension of the rotary shaft 29 of the claw lever 26 spaced.

The operating section 44 of the dental arch 41 lies in the vertical direction from above on the inclined portion thus formed 48 c on. Therefore, the claw lever 26 in comparison with the case where the opening operation receiving section 48 and the rotary shaft 42 of the dental arch 41 with a distance along the rotation shaft 29 of the claw lever 26 are arranged - even at low angle of rotation of the dental arch 41 - be operated with a long stroke. Because the dental arch 41 can be miniaturized, thus the entire device can be miniaturized.

As in the 4 to 6 B is the adjacent section 48d a plate-shaped section on the side, away from the fork 22 removing, over the inclined section 48 c is positioned. The adjacent section 48 d is through a connecting section 48 e at a distance from the inclined section 48 c, so that it is positioned in front of the direction in which the opening operation section 54 c through the opening drive of the opening lever 54 rotates. In a state in which the claw lever 26 is rotated to the locking position, the adjacent portion extends 48 d along the axis of the shaft section 54 a of the opening lever 54 ,

(Deformation protection of the base plate)

As described above, the dental arch is 41 that the operating section 44 includes, on the base plate 13 arranged, and the jaw lever 26 and the fork 22 are in the stop block 14 arranged. In addition, the drive of the electric motor causes 35 that the dental arch 41 the claw lever 26 opens and the fork 22 closes. Especially when operating the fork 22 To close, a large load acts on the rotary shaft 42 of the dental arch 41 , so a big load on the base plate 13 is applied. This will make the base plate 13 on which the rotary shaft 42 is arranged, deformed downward. To the deformation of the base plate 13 To prevent and maintain the opening / closing function for a long time is the frame 12 with a deformation-inhibiting section 57 to avoid deformation.

As in the 1 and 3 shown is the deformation-inhibiting section 57 in the rear portion of the locking base 15 so designed to be at the end on the side of the base plate 13 the locking base 15 to be positioned. The deformation-inhibiting section 57 closes a first section 57 a in the direction of the base plate 13 is bent, and a second section 57 b, in relation to the first section 57 a is bent. The second section 57 b extends in a direction orthogonal to the base plate 13 and covers the lower end of the plate-shaped base plate 13 , The second section 57 b and the lower end of the base plate 13 are arranged as close as possible to each other, in the area in which the mounting of the locking base 15 at the base plate 13 not hindered.

Next, the operation of the door lock device 10 described.

In a state where the back door 4 in relation to the vehicle body 1 , as in 7 B shown, closed, the fork turns 22 in the position of the complete lock and the jaw lever 26 turns into the locking position to the fork 22 to lock. In addition, the retaining groove holds 22 a the fork 22 the strike plate 2 , and the strike plate 2 can not get out of the insertion groove 14 a be solved.

(Opening drive by electric opening / closing mechanism)

If the opening switch the back door 4 is operated in the locked state, as in 7 A shown causes the rotation of the electric motor 35 in the normal direction, that is the output gear 36 turns clockwise and the dental arch 41 is pressed to open counterclockwise. So, as in 8 A shown, the first pen 45 of the dental arch 41 on the inclined section 48 c of the opening operation receiving section 48 , As in 8 B shown, the claw lever has 26 not yet rotated out of the locking position in this state and maintains the state in which the section for a complete locking step 22 b with the locking portion 27 a is locked.

When the rotation of the dental arch 41 progresses, pushes the first pin 45 the inclined section 48 c, the claw lever 26 turns counterclockwise. As in 9A shown when the dental arch 41 turns into a position in which the first pin 45 the lower end of the inclined section 48 c reaches, the second pin abuts 46 on the inclined section 48 c. In this state, as in 9 B is shown, the locking of the locking portion 27 a and the fork 22 not yet solved, although the rotation of the jaw lever 26 continues in the direction of the non-locking position.

When the rotation of the dental arch 41 continuing, the second pin pushes 46 the inclined section 48 c, the claw lever 26 turns counterclockwise. As in 10 A shown, the locking of the jaw lever 26 and the fork 22 solved when the second pin 46 due to the rotation of the dental arch 41 , as in 10 B shown, the lower end of the inclined portion 48 c approaches. Thus, the fork can 22 by the biasing force of the spring 24 be turned into the open position.

As in 11 A is shown, the normal rotation of the electric motor 35 stopped when the dental arch 41 turns until the second pin 46 at the lower end of the inclined section 48 c is positioned. In this state, as in 11 B shown, the jaw lever rotates 26 against the biasing force of the spring 30 in the non-locking position, and the fork 22 rotates by the biasing force of the spring 24 in the open position. This will make the strike plate 2 from the retaining groove 22 a the fork 22 solved.

When the hook switch 25 Captures that fork 22 moved to the open position, the electric motor 35 turned upside down, so that the output gear 36 turns counterclockwise and the dental arch 41 turns clockwise. Thus, the release of the pressing of the inclined portion causes 48 c through the first pen 45 and the second pen 46 , as in 12 B shown that the jaw lever 26 by the biasing force of the spring 30 from the non-locking position to the locking position. As in 12 A shown, the disturbance element switches 43 the switch 39 when turning the dental arch 41 in the neutral position, the reverse rotation of the electric motor 35 stops.

The opening drive of the electric motor 35 can be configured to be normally rotated until a predetermined time elapses from the start of the drive, and is reversely rotated upon elapse of the predetermined time. The predetermined time is preferably in advance to a length from the neutral position to the second pin 46 set the lower end of the inclined section 48 c reached. In addition, based on the detection result of the switch 21 the normal rotation and the reverse rotation of the electric motor 35 be switched. In addition, the reverse rotation of the electric motor 35 Timed instead of the neutral position of the dental arch 41 through the switch 39 capture.

As described above, since the jaw lever 26 and the dental arch 41 Three-dimensionally arranged on different surfaces, can in the door lock device 10 the arrangement surfaces for the fork 22 and the claw lever 26 be arranged space-saving, and the entire device can be miniaturized. Since the operating section 44 of the dental arch 41 the opening operation receiving section 48 of the claw lever 26 directly operated, it is also not necessary, the opening operation section 54 c of the opening lever 54 between the opening operation receiving section 48 and the operation section 44 to arrange. Therefore, it is not necessary to add extra space between the jaw lever 26 and the dental arch 41 so that the components can be arranged together, and also in this regard, the entire apparatus can be miniaturized.

(Opening drive by manual opening mechanism)

As in 2 shown when the handle portion 54 b of the opening lever 54 in the Locking state is rotated clockwise, the opening operation section abuts 54 c of the opening lever 54 on the adjacent section 48 d of the claw lever 26 and press the adjacent section 48 d to the left, as in 2 shown. Thus, the claw lever rotates 26 from the locking position to the unlocked position, and the locking of the fork 22 will be solved. Thus, the fork turns 22 by the biasing force of the spring 24 in the open position.

When the operation of the door handle is stopped, the biasing force of the spring rotates 55 the opening lever 54 from the operating position to the non-operating position. Since then pressing the adjacent section 48 d through the opening operation section 54 c is released, the biasing force of the spring rotates 30 the claw lever 26 from the non-locking position to the locking position.

As described above, allows the direct operation of the opening lever 54 in the door lock device 10 the actuation of the locking mechanism 20 in an emergency, such as when power is interrupted by the battery.

Because the opening lever 54 Only used in an emergency, occur no disturbances such as breakage, even if the mechanical load capacity decreases. Therefore, a heat treatment such as baking for the opening lever 54 not required, so that the manufacturing cost can be reduced.

(Closing drive by electric opening / closing mechanism)

As in the 12 A and 12 B shown, the strike plate occurs 2 if the back door 4 is operated to close in the open state, relative to the retaining groove 22a the fork 22 one that has turned into the open position. Then the pressure effect of the striking plate rotates 2 - by the rotation of the back door 4 - the fork 22 from the open position to the full lock position. When the fork 22 Turning from the open position to the half latch position will become half the latching step 22 c through the locking portion 27 a of the claw lever 26 locked. At this time, the hook switch detects 25 that is the fork 22 has moved to the position of half lock. This will cause the reverse rotation of the electric motor 35 started.

The reverse rotation of the electric motor 35 turns the output gear 36 counterclockwise, and the dental arch 41 is driven clockwise to close. Thus, the first pin is supported 45 of the dental arch 41 to the closing operation receiving section 50 the fork 22 , During the rotation of the dental arch 41 progresses, the first pin turns 45 of the closing operation receiving section 50 pushes the fork 22 against the biasing force of the spring 24 from the position of half lock to the position of full lock.

When the fork 22 Turns into the position of the full lock, the section for a complete locking step 22 b through the locking portion 27 a of the claw lever 26 locked. When the hook switch 25 Captures that fork 22 has moved to the position of full locking, and the jaw lever 26 moved to the locking position and the switch 21 is turned off, the electric motor turns 35 , which is rotated in the normal direction, the output gear 36 clockwise and the dental arch 41 counterclockwise. In addition, the interfering element switches 43 the switch 39 one when the dental arch 41 rotates to the neutral position, and the normal rotation of the electric motor 35 is stopped.

It should be noted that the closing drive of the electric motor 35 can be rotated in the reverse direction until a predetermined time passes from the beginning of the drive, and can be rotated in the normal direction after the predetermined time has elapsed. The predetermined time is preferably set in advance to the length which the fork 22 needed to rotate from the position of the half-lock to the position of full lock caused by the first pin 45 of the closing operation receiving section 50 suppressed. In addition, based on the detection result of the switch 21 the reverse rotation and the normal rotation of the electric motor 35 be switched. In addition, the normal rotation of the electric motor 35 timed instead of detecting the neutral position by the switch 39 ,

As described above, in the door lock device 10 the present embodiment, the locking mechanism 20 for opening by the electric opening / closing mechanism 32 or the manual opening mechanism 52 be operated. In addition, the locking mechanism can 20 for closing by the electric opening / closing mechanism 32 be operated. As the claw lever 26 and the dental arch 41 are arranged on three different surfaces on different surfaces and the jaw lever 26 directly from the dental arch 41 is actuated, each component can be arranged together and the entire device can be reliably miniaturized.

It should be noted that the door lock device 10 The present invention is not limited to the configuration of the embodiment described above and various modifications are possible.

For example, the inclined section 48 c in the jaw lever 26 trained opening operation receiving section 48 be formed in a flat surface shape without a curved surface. In addition, the arm section needs 27 b of the claw lever 26 not with the inclined section 27 c be equipped. Further, the opening operation receiving section 48 integral with the lever main body 27 be formed, which is made of metal.

The operating section 44 of the dental arch 41 consists of the first pen 45 and the second pen 46 but the operating section 44 may consist of a radially extending element in which the first pin 45 and the second pen 46 integrated, or may consist of three or more pins.

The arrangement of the actuator 34 , the dental arch 41 , which the operating section 44 includes, the opening operation receiving section 48 and the closing operation receiving section 50 can be changed if necessary, and the arrangement of the fork 22 and the claw lever 26 can also be changed if necessary. If necessary, the components that make up the frame can also be used 12 form, be exchanged.
