Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a door lock device that enables smooth operation.

(Prior art) In a door lock device, after the door is closed to engage the latch and the pawl, an electric actuator or locking button (or knob) is used to non-rotate the lift lever that interlocks with the pawl. A mechanism is provided to bring it into a dynamic state. This mechanism ensures the safety of the occupants by not opening the door even if the occupant pulls the inside handle while the vehicle is in motion.

The movement of the locking knob is transmitted to the lift lever via the locking lever, and the output lever of the actuator is also transmitted to the locking lever via the iron to operate the lift lever.

(Problems to be Solved by the Present Invention) Conventionally, the movement of the actuator is transmitted to the locking lever via the iron, and this movement is further transmitted to the foot lever, so the number of parts is large, and the output transmission path of the actuator is It is complicated, and the capacity of the actuator needs to be increased accordingly, making the entire device larger and making it difficult to fit it into a limited space.

Therefore, it is an object of the present invention to solve the above-mentioned problems.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a latch that is pivotally supported on a latch pin and receives a striker, and a pole that is pivotally supported on a pole pin so as to be freely engageable with the latch. , a lift lever disposed coaxially with the pawl pin and interlocked with the pawl, an outer lever pivotally supported by the pawl pin and holding a release button that can be freely engaged with the lift lever, and a lift lever that engages or disengages the release button with the lift lever. It has a locking link that guides it to the engagement position, and the locking link that is integrally interlocked with the output lever of the actuator has an arcuate groove that is concentric with the pawl pin and guides the release button, and the liquid groove is connected to the output lever of the actuator. To provide a door lock device, which is formed in a holding guide part of a mouth/knocking link arranged substantially perpendicular to an axis, and has a part which also receives movement of a locking knob at the other end of the locking link.

(Function) In the present invention, since the output of the actuator is directly transmitted to the release button that operates the lift lever,
The number of parts is small, and the actuator can be made smaller.

(Example) A door lock body 1 and an actuator 2 for electrically locking and unlocking are connected via a plate.

A latch 5 is rotatably attached to a latch pin 6 in a space formed by a body 3 and a base 4 of the door lock body 1, and a latch spring 7 applies rotational force in the clockwise direction as seen in FIG. Moreover, the pawl 8 is rotatably pivotally connected to the pawl pin 9, and as seen in FIG. They are arranged so that they can be disengaged when they are engaged.

The pawl 8 can be integrally interlocked with the lift lever 12 by a pin 13 fixed to the lift lever 12, and the lift lever 12 is coaxial with the pawl pin 9 and receives rotational force by a spring 14 as shown in FIG. It is arranged so that it can rotate relative to the outer lever 15 provided and can be interlocked with the outer lever 15.

The above-mentioned pole pin 9 is equipped with a collar portion 16, one end of which passes through the rotation shaft hole of the above-mentioned pole 8, and the other end passes through the hole 18 of the sub-base 17, and the lift lever 1
2 and the outer lever 15 are fixed to the sub-base 17 via a collar 19 and a washer 20.

A resin bush 21 and a washer 22 are provided on the rotating shaft of the lift lever 12 of the collar 19 to prevent metal contact with the lift lever 12. A release button 25 that can engage and disengage with an end surface 23 formed on the lift lever 12 and is slidably supported by a guide support portion 24 provided on the outer lever 15 is rotatably pivoted to a pin 26. Ronkindareper 28 and bushes 2 are worn and kept in moderation by turnover spring 27.
The holding guide portion 33 of the release button 25 of the locking link 32 is slidably supported by the resin bush 31 inserted into the pin 30 fixed to the sub-base 17, and the lock position is adjusted to the locked position. Alternatively, it is held in the unlocked position (see FIGS. 4 and 7).

The holding guide portion 33 of the release button 25 of the locking link 32 is provided with an arc-shaped 1li34 centered on the axis of the pole pin in the unlocked position, and the release button 25 moves as the outer lever 15 rotates. enable.

The bushing 29 that connects the long sleeve lever 28 and the locking link 32 will be described above with reference to FIGS. 5 and 6.

The Ronkindareper 28 is provided with a hole 35, into which a leg portion 36 having a function of preventing the bushing 29 from being removed is inserted. The foot portion 36 is provided with a bearing portion 37 having the same diameter as the hole 35 and a pull-out stop portion 38 having a larger diameter than the bearing portion 37. inserted. In order to enable elastic deformation of the foot portion 36, a space 40 is provided between the foot portion 36 and the body portion 39. The body portion 39 is provided with a shaft portion 41 that serves as the rotation axis of the hole 35 of the locking lever 28 and a shaft portion 42 that is supported by the locking link 32, but since it is provided with the hollow space 40, it has a completely cylindrical shape. I can't get it.

Therefore, Ronquin Dale Parr 28 and Locking Link 32
In order to arrange the body part 39 in the load transmission direction with respect to the body part 39, positioning is performed by the locking link 32 and the shaft part 42. The locking link 32 is provided with a positioning part 44 corresponding to the width of the shaft part 42 which is set to have a diameter larger than that of the hole 35 of the locking lever 28 and the shaft part 41. By inserting the section 42, the body section 39 is arranged in the aforementioned load transmission direction. Reference numeral 45 denotes a head, which is provided with elastic fins 46 at both ends to prevent rattling between the locking lever 28 and the locking link 32.

Next, with reference to FIG. 7, the resin bushing 31 that slidably supports the locking link 32 on the base 17 will be described in detail.

A supporting part 48 having a dimension slightly smaller than a groove 47 provided in the locking link 32, a collar part 49 having an outer diameter larger than the groove 47, and a plate of the locking link 32 working together with the collar part 49. It is provided with an elastic collar portion 50 that prevents backlash in the thickness direction and a body portion 51 that positions the sub-base 17, and the distance between the collar portion 49 and the elastic collar portion 50 is the same as the plate thickness dimension of the locking link 32. It is set narrower.

The locking link 32 also has a groove 5 into which a pin 53 fixed to the output lever 52 of the actuator 2 is inserted.
It is equipped with 4.

Further, a bushing is arranged between the pin 53 and the groove 54 to reduce operating resistance or operating noise.

A long groove 56 is provided in the guide support portion 24 of the outer lever 15, which reduces the contact area with the release button 25, reduces the operating resistance when moving to the lock position and the unlock position, and also prevents sand and dirt. When the release button 25 is operated in a situation where there is a lump or the like attached to it, the sand or lumps etc. scraped off become a groove, and the sliding part of the release button 25 is increased in operating resistance due to the sand, the lump, etc. It is possible to prevent this and obtain stable operating resistance over a long period of time. Therefore, the output of the actuator 2 can be made as small as possible, and the actuator can be made smaller and lighter.

The end portion 57 formed on the outer lever 15 is connected to the pin 5.
An inner lever 60 is rotatably mounted on the inner lever 8 and connected to an inside handle (not shown) via a snap 59.
is disposed so as to be able to engage with the end portion 61 of.

A stopper 62 is made of an elastic material such as rubber and is fixed to the sub-base 17, and cooperates with the stoppers 63 and 64 provided on the locking lever 28 to restrict the rotation of the long lever 28.

65 is a snap, which transmits the operation of a locking knob (not shown) to the locking lever 28.

The operation will be explained using the above configuration.

First, the door opening action will be described.

From the closed state of the door in FIG. 1, the inner lever 60 is rotated clockwise around the pin 58 as seen in FIG. introduce.

As a result, the outer lever 15 rotates counterclockwise around the pawl pin 9 as seen in FIG. When engaged, the lift lever 12 is rotated counterclockwise.

As a result, the lift lever 12 and the pawl 8 connected via the pin 13 can be seen in FIG.
Since the claw 11 rotates clockwise around
The latch 5 is disengaged from the pawl 10, and the latch 6 is rotated clockwise around the latch pin 6 by the latch spring 7, opening the door.

In addition, the release button 25 has a locking link 32.
Since the arc-shaped groove 34 centered around the pawl pin 9 moves, no slipping occurs between the release button 25 and the end surface 23 of the lift lever 12, and the operating force required for the above-mentioned door opening action is reduced. Furthermore, since wear and the like do not occur, a resin material can be selected for the release button 25, and an arbitrary shape can be obtained.

Next, the operation of changing from the unlocked state to the locked state will be described. When the locking lever 28 is rotated clockwise around the pin 26 as seen in FIG. 1 using a locking knob (not shown), as shown in FIG.
Since the release button 25 is lifted upward as seen in FIG. 9 while being guided by the button 31, the holding guide section 33 of the release button 25 of the locking link 32 allows the release button 25 to move upward along the guide support section 24 of the outer lever 15. , the release button 25 disengages from the end surface 23 of the lift lever 12, and the outer lever 1
5, or the door does not open even if the inner lever 60 is operated.

Also, release button 25, locking link 32
It only moves within the arc-shaped groove 34 and has no effect on other parts.

Further, when the locking link 32 is moved to the locked position or the unlocked position, the output lever 52 of the actuator 2 is simultaneously actuated by the groove 54 provided in the locking link 32 via the pin 53.

Next, the action of changing from the unlocked state to the locked state by the actuator 2 will be described.

When the power is applied in the locking direction by a switch (not shown) from the unlocked state, the output lever 5 of the actuator 2
2 is rotated clockwise as seen in FIG. 1, and the locking link 32 is lifted upward as seen in FIG. 9 by a pin 53 fixed to the tip of the output lever 52 and through the groove 54 of the locking lever 32. It will be done.

The following actions are the same as with the locking knob.

Further, the movement of the locking lever 32 is transmitted to the locking lever 28 via the bush 29, and moves a locking knob (not shown) to the lock position.

(Effects) In the present invention, since the release button holding guide part is arranged at one end of the output lever of the actuator and the locking knob connecting part is arranged at the other end, the number of parts can be significantly reduced, and weight and cost can be reduced. Furthermore, since the output lever directly operates the release button, the transmission efficiency is improved, and the actuator output can be reduced accordingly, making it possible to downsize the motor and the actuator.
