Detailed Description of the Invention

[0001]

[Object of the Invention]

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door closer device which is used as a closing mechanism for a luggage door or the like and which drives a striker by a drive mechanism to bring the door into a completely closed state with respect to the vehicle body.

[0003]

2. Description of the Related Art Heretofore, as a door closer device of this type, a device disclosed in Japanese Patent Application No. 4-289054, which is a prior application of the present invention, has been proposed. This is to pull in the latch engaged with the striker by sliding the striker through the lever from the open state to the closed state by the drive mechanism, whereby the door is not completely closed with respect to the vehicle body. From the state until the door is completely closed with respect to the vehicle body, the door is automatically closed, and even if the door is lightly operated, it resists the reaction force of the weather strip that seals between the door side and the vehicle body side. Thus, it is possible to improve the contradictory performances of the operability and the sealing property to ensure that the door is completely closed. Further, in this conventional device, the striker is allowed to slide independently in the open state in the direction of the closed state with respect to the lever, and the striker and the latch are engaged by the independent sliding action of the striker. The collision at the time of fitting is alleviated, the impact noise due to this collision is eliminated, and the impact is prevented from being applied to the drive mechanism. Note that the striker's independent sliding motion is the load (magnitude of impact) when the striker collides with the latch.
The rotational movement of the ratchet at this time is restricted by the lever, and the striker slides back to the open state when the load due to the collision is eliminated. Further, a spring urging force acts on the striker in order to prevent an unintentional independent sliding movement of the striker in the open state.

[0004]

However, in the above-mentioned conventional device, since the striker in the open state has its inadvertent independent sliding motion restricted by the urging force of the spring, the change over time, etc. If the biasing force of the spring is weakened by this, it becomes impossible to prevent the striker from sliding unintentionally independently.For example, when rotating the door in the direction of full opening, there is a gap between the door and the car body. There was a risk of problems such as making operation difficult.

SUMMARY OF THE INVENTION Therefore, it is a technical object of the present invention to provide a door closer device capable of reliably restricting the independent sliding motion of the striker in the open state.

[0006]

[Constitution of the invention]

[0007]

In order to solve the above-mentioned technical problems, the technical means taken in the present invention are as follows. The striker in the open state is disengaged from the striker, and the striker is movable. Second state and engagement with the striker to restrict movement of the striker
That is, it has a moving member to be in a state.

[0008]

According to the above technical means, the movement of the striker is restricted by setting the striker in the second state in which it is engaged with the moving member. Therefore, the striker is in a state in which the independent sliding operation in the open state is reliably restricted.

FIG. 8 shows the state of the latch mechanism 7 when the luggage room 1 is in the open state. The latch 72 has an engaging groove 72b located on the groove portion 71a so as to receive the engaging member 62b. The pawl 73 is rotatably arranged so that the claws 73b and 72c are disengaged from each other. Further, the latch position detection switch 74 is in the ON state because the engagement between the contact point 74a and the cam portion 72d is released. Figure 9 shows luggage room 1
Shows the first state when the closer mechanism 6 is in the open state when the opener is in the open state, the striker 62 is slidably arranged so as to be located at the engagement position A, and the ratchet 64 has the claw portion 64c and the claw portion 64c. The engagement with the portion 62e is released, and the restriction surface 62f and the claw portion 64c are pivotally arranged so as to be capable of contacting each other.

Further, the striker position detecting switch 68 is in the ON state because the contact point 68a and the cam surface 64d are engaged with each other.

In this state, when the person directly operates the luggage door 4 to close the luggage room 1, the engagement member 6 is rotated by the rotation of the luggage door 4.
2b is received in the engagement groove 72b while being inserted into the groove portion 71a, and the latch 72 is rotated counterclockwise in FIG. 8 against the biasing force of the spring 75. As a result, as shown in FIG.
The pawl portion 72c and the pawl portion 73b are engaged with each other by the biasing force of No. 5, the rotation of the latch 72 is restricted by the pawl 73, and the engagement groove 72b is engaged with the engagement member 62b. 62 and the latch 72 are brought into engagement with each other, and the latch position detection switch 74 causes the cam portion 72d and the contact 7 to come into contact with each other.
The engagement with 4a is released and the state is turned off. As a result,
The luggage room 1 is in a semi-closed state in which the luggage door 4 is held with respect to the vehicle body 2 in a state where the reaction force of the seal member 5 is not working, that is, the luggage door 4 and the vehicle body 2 are not completely sealed. . At this time, the striker 62
Receives the urging force of the spring 66 and remains in the engagement position A in the state shown in FIG. 9 so that the ratchet 64 is disengaged from the claw portion 64c and the claw portion 62e and the regulating surface 62 is released.
The f and the claw portion 64c are still arranged so as to be able to contact with each other, and the striker position detection switch 68 remains in the ON state due to the contact 68a and the cam surface 64d engaging with each other.

When the latch position detection switch 74 is turned off, the signal is input to the port P4 of the CPU 81, and the signals for driving the motor 65a in the normal direction are output from the output ports P1 and P2 based on the signal. Based on the signal, the motor drive circuit 82 drives the motor 65a to rotate normally. The forward rotation of the motor 65a causes the screw 65b to move through the gear mechanism and nut member as shown in FIG.
And the lever 63 rotates counterclockwise as shown in FIG. The rotation of the lever 63 causes the engagement pin 62c and the first engagement surface 63b to engage with each other, and then the striker 62 resists the urging force of the spring 66 as the stroke 65b moves and the lever 63 rotates. Then, the latch is pulled in and slid. At this time, the ratchet 64 includes the regulating surface 62f and the claw portion 64.
Since the contact with c is still maintained, the ratchet 6
4 is rotationally restricted against the urging force of the spring 67, and the disengagement of the claw portion 64c and the claw portion 62e and the ON state of the striker position detection switch 68 are maintained.
The other end of the spring 66 is in sliding contact with the side surface of the support member 62a so as to ride over the cam portion 62d. When the striker 62 is pulled in and slid, the regulating surface 62
The contact between f and the claw portion 64c is released, and the ratchet 64 is rotated counterclockwise by the urging force of the spring 67. As a result, the engagement between the contact point 68a and the cam surface 64d is released, the striker position detection switch 68 is brought into the first off state, and the claw portion 64c and the claw portion 62e are engaged. As a result, the striker 6 as shown in FIG.
2 is disposed in the retracted position B in a state in which sliding is restricted by the engagement of the claw portion 62e and the claw portion 64c (closed state). As a result, the luggage room 1 is in a completely closed state in which the luggage door 4 is held with respect to the vehicle body 2 in a state in which the reaction force of the seal member 5 is applied, that is, the luggage door 4 and the vehicle body 2 are completely sealed. . At this time, the rigidity of the luggage door 4 with respect to the vehicle body 2 is determined by the claw portion 62e and the claw portion 64c.
It is secured by the engagement with. The motor 6
In 5a, a signal indicating that the striker position detection switch 68 is in the first off state is input to the input port P3 of the CPU 81, and a signal for stopping the motor 65a is output from the output ports P1 and P2 based on the signal. Based on the signal, the motor drive circuit 82 stops. At this time, due to the structure of the motor 65a, the motor 65a continues to be normally driven by inertia and overtravels so that a predetermined gap is formed between the claw portion 64c and the claw portion 62e. Therefore, from the output ports P1 and P2 to the motor 6
5 hours after the signal for stopping 5a is output (CPU
Output port P1 and P2 from the motor 6
A signal for driving the motor 5a in the reverse direction is output, and the motor 65a is driven in the reverse direction by the motor drive circuit 82 based on the signal to rotate the lever 63 in the clockwise direction to rotate the engagement pin 6
The engagement between 2c and the first engagement surface 63b is released. As a result, as shown in FIG. 14, the striker 62 is pushed out and slid by the biasing force of the spring 66, and the pawl portion 62e and the pawl portion 64c are completely engaged with each other, which is shown in FIG. Will be arranged at the retracted position B. In the reverse rotation drive of the motor 65a, a signal for stopping the motor 65a is output from the output ports P1 and P2 after a predetermined time (measured in the CPU 81) after the signal for reverse drive of the motor 65a is output from the output ports P1 and P2. The motor 65a is stopped by the motor drive circuit 82 based on the signal. Further, when the motor 65a is driven in the reverse direction described above, the second engagement surface 63c and the engagement pin 6 are
A predetermined gap is formed between the engagement pin 64b and the second engagement surface 63c in a state where the striker 62 is arranged at the retracted position B so as not to engage with 4b.

In the state shown in FIGS. 6 and 10, that is, the latch 72 and the striker 62 are engaged with each other, the rotation of the latch 72 is restricted by the pole 73, and the striker 62 is placed in the retracted position B and the ratchet 64 is attached. Therefore, in the completely closed state of the luggage room 1 in which the sliding of the striker 62 is restricted, the opener (not shown) in the vehicle compartment is operated to rotate the pole 73 against the urging force of the spring 75 and to rotate the pawl portion. When a person directly rotates the luggage door 4 to release the engagement between the claw portion 73b and the claw portion 72c and to open the luggage room 1, the latch 72 is moved to the striker 62 by the rotation of the luggage door 4. 1 by the biasing force of the spring 75.
Rotate in the clockwise direction 0 to engage the engaging member 62d and the engaging groove 72b.
The engagement with the cam portion 72d and the contact point 74a
Is disengaged. Therefore, the luggage room 1 is opened and the latch position detection switch 74 is turned on.

When the latch position detection switch 74 is turned on, the signal is input to the port P4 of the CPU 81, and a signal for driving the motor 65a in the reverse direction is output from the output ports P1 and P2 based on the signal. Based on the above, the motor drive circuit 82 drives the motor 65a to rotate in the reverse direction. The reverse rotation of the motor 65a causes the screw 65b to move in the F direction shown in FIG. 10 through the gear mechanism and nut member, and the lever 63 to rotate clockwise in FIG. By this rotation of the lever 63, the engagement pin 64b and the second engagement surface 63c are engaged with each other, and the ratchet 64 is rotated against the urging force of the spring 67, so that the claw portion 62e and the claw portion 64c are rotated. Is disengaged. At this time, as the lever 63 rotates, the engagement between the engagement pin 62c and the first engagement surface 63b is released, so that the striker 62 as shown in FIG.
Is pushed and slid by receiving the urging force of the spring 66, and is returned to and arranged at the engagement position A as shown in FIG.

In the motor 65a, the contact 68a and the cam surface 64d are engaged with the rotation of the ratchet 64 to turn on the striker position detection switch 74, so that the signal is input to the input port P3 of the CPU 81. A signal that is input, and a signal for stopping the motor 65a is output from the output ports P1 and P2 based on the signal, and is stopped by the motor drive circuit 82 based on the signal.

In the completely closed state of the luggage room 1 shown in FIGS. 6 and 10, the pushing switch 6 in the passenger compartment is opened.
9 is operated to input the signal to the input port P5 of the CPU 81, the output ports P1 and P are output based on the signal.
2 outputs a signal for driving the motor 65a in the reverse direction, and the motor drive circuit 82 uses the signal to drive the motor 6a.
5a is driven in reverse. As a result, as described above, the lever 63 rotates clockwise in FIG. 10 and the ratchet 64 rotates to release the engagement between the claw portion 62e and the claw portion 64c, and the striker 62 is disposed at the engagement position A. Then, the rotation of the lever 63 is further continued, the engaging member 62b and the contact convex portion 62e contact each other, and the striker 62 is pushed out by the lever 63. As a result, the striker 62 is shown in FIG.
The second state is the open state shown in FIG. At this time, the ratchet 64 also continues to rotate due to the engagement between the second engagement surface 63c and the engagement pin 64b. When the striker 62 is arranged at the push-out position C, the contact point 68a and the cam portion 64e are engaged by the rotation of the ratchet 64, and the striker position detection switch 68 becomes the second off state, and the signal is input to the input port P3. To be done. As a result, a signal for stopping the motor 65a is output from the output ports P1 and P2 based on the signal, and the motor drive circuit 82 stops the motor 65a based on the signal. When the striker 62 is arranged at the push-out position C, the abutment of the engagement member 62b and the abutment protrusion 63e restricts the independent pull-in sliding of the striker 62, which will be described later.

In the second state in the open state in which the striker shown in FIG. 11 is arranged at the pushing position C,
When the return switch 70 is operated and the signal is input to the input port P6 of the CPU 81, a signal for driving the motor 65a in the normal direction is output from the output ports P1 and P2 based on the signal, and the motor is output based on the signal. The drive circuit 82 drives the motor 65a to rotate normally. As a result, as described above, the lever 63 rotates counterclockwise in FIG. 11 and the striker 62 is opened as shown in FIG. 9 due to the engagement between the first engagement surface 63b and the engagement pin 62c. The first state is set to the engagement position A. At this time, the ratchet 64 receives the urging force of the spring 67 and the lever 6
It rotates in accordance with the rotation of 3. When the striker 62 is placed at the engagement position A, the contact point 68a and the cam portion 64d are engaged by the rotation of the ratchet 64, the striker position detection switch 68 is turned on, and the signal is input to the input port P3. It As a result, a signal for stopping the motor 65a (measured in the CPU 81) after a predetermined time is output from the output ports P1 and P2 based on the signal,
Based on the signal, the motor drive circuit 82 drives the motor 6
5a is stopped. When the striker 62 is located at the engagement position A, the engagement member 62b and the contact protrusion 6 are
Since the contact with 3e is released, the striker 62 can be independently pulled in and slid later.

The luggage room 1 shown in FIGS. 8 and 9.
When the luggage door 4 is swung with a force in the open state, the striker 62 strikes as shown in FIG. 16 due to the collision / engagement between the latch 72 and the striker 62.
Only the latch position pulls the latch independently from the engagement position A against the biasing force of the spring 66. As a result, the collision between the striker 62 and the latch 72 is effectively mitigated. At this time, the lever 63a is not rotated, and the engagement between the engagement pin 64b and the second engagement surface 63c is maintained as shown in FIG. 9, so that the rotation of the ratchet 64 is restricted. As the striker 62 slides, the claw portion 62e and the claw portion 6
4c does not engage. After that, the striker 62 is returned to the engagement position A again by the biasing force of the spring 66 as the collision between the latch 72 and the striker 62 is eliminated, and the striker 62 is driven by the forward rotation of the motor 65a. The latch pulls in and slides.
Further, when the striker 62 slides in and pulls in the latch, the other end of the spring 66 slides into contact with the side surface of the support member 62a. The size of the collision / engagement is such that the other end of the spring 66 gets over the cam portion 62d.

The contact 68a of the striker position detection switch 68 is used to detect the pushing position C of the striker 62.
Instead of engaging the cam portion 64e with the cam portion 64e, another switch may be used, for example, a switch that engages / disengages with the cam portion 64d or a switch that engages / disengages with the lever 63. Further, the arrangement of the striker 62 in the second state in the open state may be the same as the arrangement of the striker 62 in the first state in the open state, that is, the engaging position A and the pushing position C. In this case, the first state and the second state are distinguished by the engagement / disengagement of the engagement member 62b and the contact protrusion 63e. Further, in this case, without providing the return switch 70, the motor 65a is normally driven immediately after a predetermined time after the striker 62 is set to the second state or based on an arbitrary signal that the luggage door 4 is opened. First
You may make it a state.

Further, when the latch pull-in sliding of the striker 62 is not completed within a fixed time or an overcurrent is generated in the motor 65a due to the clothes or the like being sandwiched between the luggage door 4 and the vehicle body 2 ( (When an operation abnormality occurs), the motor 65a is driven in the reverse direction to drive the striker 62
May be pushed out and slid to the push position C. This makes it possible to easily eliminate the cause of the operation abnormality in the latch pull-in sliding of the striker 62.

As shown in FIG. 13, the latch mechanism 7 may be provided with a pole drive mechanism 77. The pole drive mechanism 77 includes a solenoid 77a fixed to the base 71, a leg 73c of the pole 73 connected to the solenoid 77a, and a drive rod 77b engaging and disengaging. This enables the control circuit 8 to perform related control between the closer mechanism 6 and the latch mechanism 7, and for example, the striker 62.
When the latch 72 is rotated from the engaging position A to the pushing position B by the striker 62 and the claw portion 72c and the claw portion 73b are inadvertently engaged with each other, the latch position detection switch 74 is detected. By changing the state from the on state to the off state, it is possible to operate the pole drive mechanism 77 and immediately perform control such that the claw portions 72c and 73b are disengaged.

As shown in FIG. 14, the striker 62 is
The pin 62g may be rotatably supported on the base 61, and the striker 62 may be rotated to move the striker to the engagement position A, the retracted position B, and the push-out position C. Alternatively, the striker 62 and the screw 65b of the drive mechanism 65 may be directly connected by engaging the elongated hole 65d provided in the screw 65b and the engagement pin 62c of the striker 62 without using the lever 63.
In this case, the elongated hole 65d is an elongated hole having a size that allows the striker 62 to move independently, and the ratchet 64 is not necessary. The striker position detecting switch 68 is disengaged from the cam portion 65e provided on the screw 65b.

As shown in FIG. 15, the striker 62 is
Drive mechanism 6
It may be driven by a drive mechanism 655 other than the drive mechanism 655. This drive mechanism 655 is a back and forth screw 65
5a, the striker 62 is arranged at the push-out position C by the engagement of the cam portion 655b formed on the striker 655a with the forward movement of the screw 655a and the engagement member 62b of the striker 62.

According to the present invention, since the striker is brought into the second state in which the striker is engaged with the moving member, the movement of the striker in the open state can be surely restricted. As a result, a state in which the striker is prevented from inadvertently sliding independently can be obtained. For example, when the door is rotated in the fully open direction, the gap between the door and the vehicle body is difficult to perform. It is possible to solve the problem such as becoming. Further, since the second state is the push-out position projecting from the engagement position of the striker, the door is forcibly rotated even if the door does not rotate due to freezing when the door is changed from the closed state to the open state. The frozen state can be avoided. Furthermore, since the moving member is a lever that links the striker and the drive mechanism and moves the striker from the open state to the closed state by the moving operation, control of the drive mechanism that operates the striker from the open state to the closed state The striker can be brought into the second state with a simple structure including only the finger.
