[0001]
BACKGROUND OF THE INVENTION
The present invention provides a fully-open lock mechanism that restricts movement of the slide door in the closing direction when the slide door is fully opened, and a fully-closed mechanism that restricts movement of the slide door in the open direction when the slide door is fully closed. The present invention relates to a slide door lock control device capable of selectively operating a lock mechanism.
[0002]
[Prior art]
As disclosed in Japanese Patent Application Laid-Open No. 10-317756, a vehicle sliding door is provided on a side portion of a vehicle body and supported by upper, center, and lower rails fixed to the side portion of the vehicle body. It is configured to be slidable in the longitudinal direction of the vehicle along the rail. The slide door is provided with an outside handle on the outer side and an inside handle and an inside lock knob on the inner side. In addition, a fully-closed lock mechanism that maintains the closed state of the slide door is disposed at the front and rear ends of the slide door, and a fully-open lock mechanism that ensures the open state of the slide door is disposed at the lower front end of the slide door. ing.
[0003]
The fully-closed lock mechanism and the fully-open lock mechanism of the sliding door are operated by a lock control device that interlocks with the movement of each handle. The fully-closed and fully-open lock mechanism and the lock control device are disclosed in, for example, Japanese Patent Laid-Open No. 10-937. Is disclosed. These full-close and full-open lock mechanisms basically comprise a striker provided at the rear end of the vehicle body and the guide rail, and a latch that is rotatably supported by the slide door. By removing the slide door, the slide door is opened and closed and the open / closed state is maintained.
[0004]
[Problems to be solved by the invention]
In the conventional example described above, when the outside handle is moved to fully open the slide door, the movement of the outside handle is transmitted to the fully-closed lock mechanism via the lock control device, and the latch and striker are moved. Release the engagement. When the sliding door reaches the fully open position, the latch and the striker are brought into an engaged state via the fully open lock mechanism. When the outside handle is operated to close the fully open slide door, the movement of the outside handle is transmitted to the fully open lock mechanism via the lock control device, and the striker and latch are disengaged. The sliding door can be moved in the closing direction.
[0005]
However, since the movement of the outside handle is transmitted to the lock control device via the rod, the operation is made heavy by the frictional resistance of the connecting portion and the efficiency of transmission of the operating force is deteriorated due to the bending of the rod.
[0006]
In addition, since the release lever of the fully open lock mechanism and the release lever of the fully closed lock are pivotally supported on the same axis, each handle with a different required operating stroke can be handled with an outside handle whose operating stroke cannot be changed due to specifications. Therefore, it is necessary to adjust the stroke of the mechanism in the lock control device by changing the lever ratio on the counterpart lever side, so there is a tendency for the lever to become large, which is a factor in increasing the size of the lock control device. .
[0007]
Therefore, the present invention directly transmits the operating force of the swinging outside handle to the first lever that releases the fully-closed lock mechanism and the second lever that releases the fully-open lock mechanism, respectively. It is an object of the present invention to provide a slide door lock control device in which each lever is disposed at an optimal position with good transmission efficiency.
[0008]
[Means for Solving the Problems]
According to the first aspect of the present invention, a fully-closed locking mechanism that engages when the sliding door that is slidable in the front-rear direction of the vehicle body is fully closed to restrict the opening operation of the sliding door, and engages when the sliding door is fully opened. In a slide door lock control device that operates a fully-open lock mechanism that regulates the closing operation of the slide door, it swings around the pivot point by the operation of the outside handle that can rotate in the door opening direction and the door closing direction. The first and second levers that selectively receive the swinging motion of the output arm portion at the engaging portion are pivotally supported by different shafts, respectively, and the first lever is operated by the operation of the outside handle in the door opening direction. When the output arm that swings to swing in contact with the engaging portion, releases the fully closed lock mechanism, the second lever is swung by the door closing direction of the operation of the outside handle Output arm portion by swinging in contact with the engagement portion that, together with releasing the fully open lock mechanism, the output arm is disposed intermediate of the engaging portion of the first lever and the second lever In the neutral state where no input is received, the first and second levers are arranged in a C shape that is narrower than the pivotal support portion on which the engagement portion side is pivotally supported and faces each other .
[0009]
According to the first aspect of the present invention, since the first lever and the second lever are pivotally supported by different axes, they can be pivotally supported at an optimum position according to the required stroke of each lever. Therefore, the size of the lever can be minimized, and the lock control device can be miniaturized. Further, since the output arm portion is disposed between the engaging portion of the first lever and the second lever, the operation stroke of the outside handle is minimized, and the lock control device can be further downsized. In addition, since there is no need to interpose other parts, the number of parts can be reduced.
[0011]
Further, according to the first aspect of the invention, narrower than the pivot portion that is engaging portion side is rotatably supported, when being arranged in V-shape facing each other, the output arm part and the first lever and the output arm Since the position where the transmission efficiency where the swinging direction of the head and the second lever coincide with each other can be arranged within the swinging range, the output arm portion can be swung in either the first lever or the second lever. In this case, the swing operation can be performed with a small stroke, and the operability is improved.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. Reference numeral 1 denotes a sliding door that is slidably supported in the front-rear direction by an upper rail 2a, a central rail 2b, and a lower rail 2c with respect to the vehicle body. A fully open lock mechanism 4 that engages with the fully open lock striker 3 on the vehicle body side and maintains the fully open state of the slide door 1 is disposed at the lower front end in the slide door 1. On the other hand, a fully-closed lock mechanism 6 that is engaged with the fully-closed lock striker 5 on the vehicle body side and maintains the fully-closed state of the slide door 1 is disposed at the rear end portion in the slide door 1. A lock control device 20 for controlling the full-open lock mechanism 4 and the full-close lock mechanism 6 is disposed in the middle portion of the front end of the slide door 1, and the full-open lock mechanism 4 and the full-close lock mechanism 6 are respectively connected by transmission wires 8a and 8b. It is connected. The slide door 1 is provided with an outside handle 9, an inside handle 10, an inside lock knob 11, and a child lever 12 as operation members (see FIG. 1).
[0013]
The outside handle 9 is supported on the outer surface of the slide door 1 so as to be swingable in the front-rear direction by a shaft 9a that faces in the vertical direction. When the slide door 1 is fully closed, the outside handle 9 is moved rearward, that is, the slide door 1 is opened. When it is swung in the direction, the fully-closed lock mechanism 6 is released, and the slide door 1 can be opened rearward. Further, when the outside handle 9 is swung forward, that is, in the closing direction of the slide door 1 when the slide door 1 is fully opened, the fully open lock mechanism 4 is released, and the slide door 1 can be closed forward. .
[0014]
The outside handle 9 integrally has a bifurcated engagement arm 9b on the inner side of the vehicle, and the engagement arm 9b is bent at the upper end of the operating lever 13 rotatably supported by a shaft 13b. The one part 13b is clamped. With this configuration, when the outside handle 9 is swung, the input piece 13b held by the engaging arm 9b is moved accordingly, and the operating lever 13 also rotates about the shaft 13a. At the lower end of the actuating lever 13, an output arm portion 13c is formed in which contact protrusions 13b projecting in an arc shape are formed on both side edges facing in the circumferential direction (see FIG. 2).
[0015]
The inside handle 10 is fixed to the main shaft 7 of the lock control device 20 protruding from the inner surface of the slide door 1 and is normally in a neutral position. However, when the slide door 1 is fully closed, the inside handle 10 is moved clockwise in FIG. When it is swung, the fully-closed lock mechanism 6 is released and the slide door 1 can be opened rearward. When the inside handle 10 is swung counterclockwise when the slide door 1 is fully opened, the fully open lock mechanism 4 is released, and the slide door 1 can be closed forward.
[0016]
The inside lock knob 11 protrudes into the slide door 1 and is swingably supported in an unlocked state above and in a locked state below. When the inside lock knob 11 is in the locked state, even if the outside handle 9 and the inside handle 10 are operated, it becomes invalid, and the fully closed lock mechanism 6 is not released.
[0017]
The child lever 12 for switching the setting release of the child proof function is supported by the lock control device 20 so that the operation portion 12a protrudes from the front edge portion of the slide door 1 and can be switched in the vertical direction. The child proof function prevents the sliding door 1 from being accidentally opened during traveling due to an infant's mischief in the vehicle. When this function is set, the release operation of the fully-closed lock mechanism 6 at the inside handle 10 is prevented. It becomes invalid and only the operation of the outside handle 9 becomes valid. When the child lever 12 is positioned below, even if the inside handle 10 is released in the child proof function setting state, it becomes invalid and the fully closed lock mechanism 6 is not released. When the child lever 12 is positioned above, the operation of the inside handle 10 is effective in the state where the child proof function is released. The child lever 12 can be operated only when the slide door 1 is open.
[0018]
The structure for the operation of the lock control device 20 and its operating force transmission path will be described with reference to FIGS.
[0019]
An outside lever 22, a release lever 23, and an inside lever 24 are coaxially supported by the main shaft 7 at the center of the base plate 21. One end of the main shaft 7 is serrated, protrudes through the base plate 21 to the inside of the vehicle, and the inside handle 10 is fixed to the tip thereof. An inside lever 24 is fixed to the other end of the main shaft 7, and an outside lever 22 and a release lever 23 are rotatably supported at an intermediate portion of the main shaft 7. That is, the main shaft 7 has a three-layered structure in which the release lever 23 and the outside lever 22 are pivotally attached in this order from the surface of the base plate 21 and the inside lever 24 is fixed to the tip portion. (See Figure 10)
[0020]
The outside lever 22 has an input arm portion 22b in which a tongue-like engagement piece 22a that receives an operation force from the operating lever 13 is bent at one end, and the input arm portion 22b has a reverse L A letter-shaped cam hole 22c is formed. The cam hole 22c includes a transmission long hole portion 22 that can freely move a switching pin 26 of the knob lever 25, which will be described later, and extends in the radial direction from the swing center of the outside lever 22, and an upper end portion of the transmission long hole portion 22d. And an escape recess 22e extending from the center of oscillation of the outside lever 22 along the circumferential direction. Further, the outside lever 22 is provided with a child long hole 22f extending in the radial direction from the swing center of the outside lever 22 so that the floating pin 27 of the child lever 12 can move freely. Further, a balance arm portion 22g is formed on the opposite side of the outside arm 22 across the main shaft 7 of the input arm portion 22b, and the tip thereof has a fan-like shape to increase the weight effect. This is a state in which the outside lever 22 is balanced in weight from the center of swinging so that the outside lever 22 does not swing excessively due to inertial force when an impact is applied to the lock control device 20 such as a vehicle collision. By doing so, the fully-closed lock mechanism 6 is prevented from being erroneously released. The outside lever 22 is biased counterclockwise by a tension spring 28.
[0021]
The release lever 23 is provided with a long hole 23a extending in the radial direction from the center of swinging for transmitting the operating force from the outside lever 22 on one end side, and the other end with the fully closed lock mechanism 6. The other end of the transmission wire 8b having one end connected is connected. The release lever 23 is urged counterclockwise by a tension spring 29 and abuts against a stopper 21 a erected on the base plate 21. Reference numeral 21f denotes a stopper provided on the base plate 21 that restricts the swinging of the outside lever 22 in the clockwise direction in FIG.
[0022]
The knob lever 25 is pivotally supported on the base plate 21 by a shaft 25a, and can swing between a locked position and an unlocked position. One end of the knob lever 25 engages with a fan-shaped hole 21b drilled in the base plate 21, serves as a stopper that regulates the swing range, and generates a sense of moderation and detents with the base plate 21. A coil spring 30 is provided. On the other end side of the knob lever 25, a long groove portion 25b for holding the switching pin 26 slidably in the longitudinal direction is formed, and the inside lock knob 11 is fixed to a boss portion that protrudes to the inside of the knob lever 25. . Further, a transmission rod 31 for connecting to the key cylinder 36 is connected via a holder 31a.
[0023]
The switching pin 26 penetrates the cam hole 22c of the outside lever 22 and is supported at both ends by a long groove portion 25b of the knob lever 25 and a long hole 23a of the release lever 23 so as to be slidable. When the knob lever 25 is locked and unlocked, the switching pin 26 moves in the transmission elongated hole portion 22 d of the outside lever 22 as the knob lever 25 swings. When the knob lever 25 is in the locked position, the switching pin 26 is positioned at the upper end of the transmission long hole portion 22d of the cam hole 22c facing the escape recess 22e.
[0024]
When the outside handle 9 is swung backward, which is the fully-closed unlocking direction, the operation lever 13 is swung counterclockwise. The contact protrusion 13b of the output arm 13c of the operating lever 13 contacts the engagement piece 22a of the outside lever 22, and swings the outside lever 22 in the clockwise direction. Here, when the knob lever 25 is in the unlocked state, the switching pin 26 moves to the lower end portion of the transmission long hole portion 22d of the cam hole 22c, so that the swinging of the outside lever 22 is performed via the switching pin 26. It is transmitted to the release lever 23. At this time, the switching pin 26 moves in the long groove portion 25b of the knob lever 25 as the outside lever 22 swings (see FIG. 5).
[0025]
When the knob lever 25 is in the locked state, even if the outside lever 22 is swung, the switching pin 26 enters the escape recess 22e of the cam hole 22c, and the swing of the outside lever 22 is transmitted to the release lever 23. Not (see FIG. 8).
[0026]
The inside lever 24 includes a cylindrical portion 24a that rises in a cylindrical shape, a spring pressing portion 24b that is bent into a flange shape at the tip of the cylindrical portion 24a, and a pair of spring support claw portions 24c in which a part of the spring pressing portion 24b is bent. And have. The neutral return spring 32 includes a coil portion 32a wound in a circular shape and two arm portions 32b and 32b protruding from the coil portion 32a. The neutral return spring 32 is supported on the inner periphery of the coil portion 32 a by both cylindrical portions 24 a of the inside lever 24, and the middle of both arms 32 b and 32 b is engaged with the spring support claw 24 c of the inside lever 24. Further, the ends of the arm portions 32b, 32b of the neutral return spring 32 are engaged with spring receiving portions 21c provided upright on the base plate 21 from the same direction as the spring support claws 24c. The inside lever 24 is held in a neutral state by the action of the neutral return spring. That is, when the inside lever 24 is swung clockwise to release the fully-closed locking mechanism 6 and counterclockwise to release the fully-opening locking mechanism 4, one arm 32b of the neutral return spring 32 is obtained. Is pressed by the spring support claw 24c and separated from the spring receiving portion 21c. At this time, the other arm portion 32b is pressed against the spring receiving portion 21c to be elastically deformed, and accumulates a biasing force for returning to neutral. When the operation of the inside handle 10 is stopped here, the inside lever 24 returns to the neutral position by the urging force of the other arm portion 32b that has been elastically deformed. When the neutral return spring 32 is in the neutral position, the urging forces of both the arm portions 32b and 32b are balanced, and the inside lever 24 is held in the neutral position.
[0027]
The other end of a transmission rod 34 connected to a long hole 33a of the handle lever 33 described later is pivotally attached to the inside lever 24 via a holder 34a. Further, a jaw portion 24 d that can be engaged with the floating pin 27 that is slidably supported by the child lever 12 is formed on the outer peripheral portion of the inside lever 24. Reference numerals 24e and 24e are stopper portions that come into contact with the spring receiving portion 21c of the base plate 21 at the end of the swing range.
[0028]
In order to release the fully open lock mechanism 4 with the inside lever 24, when the inside handle 10 inside the vehicle is swung in the releasing direction, the inside lever 24 is rotated counterclockwise via the main shaft 7. With this swing, the handle lever 33 is swung counterclockwise via the transmission rod 34. As a result, the release operation of the inside lever 24 is transmitted to the full open lock mechanism 4 via the transmission wire 8a connected to the handle lever 33, and the full open lock mechanism 4 is released (see FIG. 6).
[0029]
A child lever 12 formed of an elastically deformable resin material is pivotally supported on the base plate 21 by a shaft 12d so as to be swingable between a set position and a release position. The child lever 12 protrudes outward from the edge of the slide door 1 and has an operation portion 12a for switching between a setting position and a release position, and a long groove portion 12e for holding the floating pin slidably in the longitudinal direction. A switching arm portion 12b having a check arm for generating a check force by elastically deforming the embossed protrusion 21d formed on the base plate 21 in order to give a sense of moderation in the switching operation between the setting position and the release position and for detent It is comprised from the part 12c. The range of swinging of the inside lever 24 is restricted by the side edges of the operation portion 12a coming into contact with the pair of stoppers 21e and 21e provided upright on the base plate 21.
[0030]
When the child lever 12 is swung to the release position, the idle pin 27 is positioned to the right in the child long hole 22 f of the outside lever 22. In this state, the floating pin 27 can be engaged with the jaw portion 24d of the inside lever 24. When the inside lever 24 is swung clockwise, the jaw portion 24d is engaged with the floating pin 27. Is transmitted to the outside lever 22 via the idle pin 27, and the fully closed lock mechanism 6 is released (see FIG. 9).
[0031]
When the child lever 12 is swung to the set position, the idle pin 27 is positioned to the left in the child long hole 22 f of the outside lever 22. In this state, the floating pin 27 cannot be engaged with the jaw portion 24d of the inside lever 24, and even if the inside lever 24 is swung clockwise, the jaw portion 24d does not engage with the floating pin. Is not transmitted to the outside lever 22 (see FIG. 9).
[0032]
The handle lever 33 is pivotally supported on the base plate 21 by a shaft 33b, and the handle lever 33 is urged clockwise by a tension spring 35. The handle lever 33 is formed with an arc-shaped long hole 33a centering on the shaft 33b. The other end of the transmission rod 34, one end of which is connected to the inside lever 24, is the holder of the long hole 33a. Fixed to 34a and slidably fitted. Further, the other end of the transmission wire 8 a having one end connected to the fully open lock mechanism 4 is fixed to the handle lever 33. Further, on the outer periphery of the handle lever 33, a tongue-like engagement piece 33c that is bent and engaged with the contact protrusion 13d of the operation lever 13 is formed.
[0033]
When the outside handle 9 is swung forward, which is the release direction of the fully open lock mechanism 4, the operation lever 13 is swung clockwise. The contact protrusion 13d of the output arm portion 13c of the operating lever 13 contacts the engagement piece 33c of the handle lever 33, and the handle lever 33 is swung counterclockwise. By the swing of the handle lever 33, the release operation is transmitted to the fully open lock mechanism 4 via the transmission wire 8a, and the fully open lock mechanism 4 is released (see FIG. 4).
[0034]
The engagement piece 33c of the handle lever 33 and the engagement piece 22a of the outside lever 22 are arranged in a letter C shape, with the contact protrusion 13d of the output arm portion 13c of the operating lever 13 sandwiched therebetween. The positional relationship among the shaft 13a of the operating lever 13, the shaft 33b of the handle lever 33, and the main shaft 7 of the outside lever 22 is such that the output arm portion is in a neutral state (FIGS. 3 and 13) in which the outside handle 9 is not operated. There is a swing range of the handle lever 33 and the outside lever 22 on both sides of the center 13c. That is, on the line L1 connecting the center of the shaft 13a of the operating lever 13 and the center of the shaft 33b of the handle lever 33, and on the line L2 connecting the center of the shaft 13a of the operating lever 13 and the center of the main shaft 7 of the outside lever 22. When the output arm portion 13c is positioned, the swinging directions at the engagement points of the operation lever 13 and the handle lever 33 and between the operation lever 13 and the outside lever 22 coincide. Since the lines L1 and L2 are in the vicinity of the center inside the swing range, the transmission efficiency from the operating lever 13 is the best for both levers. For this reason, in order to transmit a predetermined stroke to both levers, the actuating lever 13 has only to be swung in a small range regardless of whether it is swung in either direction, and the operability is extremely good.
[0035]
Further, since the arcuate contact protrusion 13d is formed at the distal end of the output arm portion 13c of the operating lever 13, any engagement angle of the operating lever 13 can be changed to the mating engagement pieces 22a, 33c. The contact is smooth and the operability is improved.
[0036]
【The invention's effect】
According to the first aspect of the present invention, since the first lever and the second lever are pivotally supported by different axes, they can be pivotally supported at an optimum position according to the required stroke of each lever. Therefore, the size of the lever can be minimized, and the lock control device can be miniaturized. Further, since the output arm portion is disposed between the engaging portions of the first lever and the second lever, the operation stroke of the outside handle is minimized, and the lock control device can be further downsized. In addition, since there is no need to interpose other parts, the number of parts can be reduced.
[0037]
According to the second aspect of the present invention, the output arm portion and the first lever are provided when the gap between the engagement portion side with the outside handle is arranged in a narrower shape than the pivotally supported portion. In addition, since the position where the transmission efficiency in which the swinging direction of the output arm unit and the second lever are the same can be arranged within the swinging range, the output arm unit is in the direction of the first lever or the second lever. Even when it is swung, it can be swung with a small stroke, improving operability.
