Description

[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology belongs to the technical field of electromagnetic automatic locking and unlocking of the sliding door of a van-type vehicle or the like when the sliding door is locked and unlocked from the driver's seat.

Therefore, this invention is designed to lock and unlock a sliding door that opens and closes back and forth along a guide rail installed horizontally on the side of the body of an automobile such as a van-type vehicle. The rod provided on the lock knob that links the handle provided with the key cylinder is further linked with the forward/backward operation rod end of the electromagnetic coil provided on the body side at the end of the sliding door, allowing automatic locking to be performed by remote control from the driver's seat. This invention relates to a locking/unlocking operation device that can be unlocked, and in particular, the slide rod itself is movable forward and backward through an electromagnetic coil fixed to the body side, and another electromagnetic coil to excite the slide rod is wound around the slide rod. This invention relates to an operating device for locking and unlocking a car, which engages and disengages from a door-side rod through magnetization and demagnetization.

<Prior Art> As is well known, there are various types of automobiles, but as shown in Fig. 1, there are so-called van types,
Wagon type cars 1 have been widely used, and recently,
It has come to be used by families and groups for leisure purposes.

Therefore, the number of passengers increases, and the frequency of entry and exit increases. Therefore, in addition to the hinged door 3 provided on the front side of the body 2 of the automobile 1, a sliding door 4 is provided on the body 2, and a guide rail installed horizontally on the body side. It is opened and closed by moving it forward and backward along the line 5.

As a matter of course, the sliding door 4 is provided with a locking/unlocking mechanism, but basically, as shown in FIG. The rod 10 for locking and unlocking is connected to the pin 11.
The inner and outer handles 1 are connected to the subrod 13 via the link 12 pivoted to the sliding door 4.
4 to unlock and open/close the door, and the guide 15 to push down the lock knob 16, which can be vertically displaced in parallel, to fix and lock the link 12, and to pull it upward to enable the unlocked state. In addition, the key cylinder 17 is linked to the lock knob 16 via a link rod 18 for locking and unlocking.

<Problems to be solved by the invention> However, as mentioned above, there is a lot of ingress and egress, especially from the center seat, rear seat, etc., which utilizes the opening and closing of the sliding door 4.
For safety reasons, the frequency of locking and unlocking 6 from the driver's seat has increased comparatively. Therefore, if the situation shown in Fig. 2 remains as it is, it will be difficult to perform operations by leaving the driver's seat each time, or to perform operations by leaving the driver's seat each time. Since locking and unlocking is performed by extending the length of the lock, it has the disadvantage that it is extremely difficult to do so.

Therefore, it is conceivable to install an electromagnetic lock/unlock operating device inside the sliding door 4, but compared to a hinge mechanism, it is difficult to connect the internal and external circuits of the sliding door 4, which moves rapidly back and forth, and has a water-resistant seal. There are also problems with durability.

To deal with this, for example,
As shown in the publication, there is an electromagnetic lock on the body side,
A technology has been devised that allows for remote control by installing an unlocking device, but since the connection between the fixed body side and the movable side sliding door is based on a link-type mechanical mechanism, the locking/unlocking mechanism is extremely difficult. It has the disadvantage of being complicated, requires a large number of man-hours for manufacturing and assembly, and has the disadvantage of high cost.Furthermore, it has the disadvantage that maintenance is not easy.

The purpose of this invention is to solve the problem of the remote automatic operation of locking and unlocking the sliding door of a car from the driver's seat based on the above-mentioned conventional technology. Instead of a complicated mechanical connection, the connection and disconnection of the rod with the slide rod that advances and retreats from the electromagnetic coil on the side is replaced with a simple magnetic connection mechanism, which is efficient, can be operated reliably, and is easy to manufacture and assemble. It is an object of the present invention to provide an excellent automobile lock/unlock operation device that can be easily performed at low cost and has fewer failures, which is useful for the field of safety technology application in the transportation industry.

<Means for solving the problems> In order to solve the above-mentioned problems, the structure of this invention, which is based on the above-mentioned claims for utility model registration in accordance with the above-mentioned purpose, is to move freely forward and backward along a guide rail provided on the body. An operating device for locking/unlocking a vehicle that can freely switch between locking and unlocking a sliding door equipped with a locking knob, the sliding door side of a rod made of magnetic material linked to a lock knob. A slide rod made of a magnetic material that faces the front end of the rod and can freely come into contact with and separate from the front end of the rod is inserted into one electromagnetic coil fixed to the body side so as to be able to move forward and backward, while another electromagnetic coil that excites the slide rod The one electromagnetic coil and the other electromagnetic coil are connected to the switch via a relay having a delay circuit that operates with a time delay relative to the other electromagnetic coil than the one electromagnetic coil. This is an operating device for locking and unlocking the connected vehicle.

<Function> Thus, the linking end of the lock and unlocking rod provided in the sliding door, which opens and closes by moving forward and backward along the guide rail installed horizontally on the body of the automobile, faces the end of the sliding door. On the other hand, another electromagnetic coil is wound around a slide rod made of a magnetic material that is inserted through an electromagnetic coil provided on the body side, and the other electromagnetic coil is excited to magnetize the slide rod.
The rod of the sliding door is magnetically attached and connected to the rod, and the former electromagnetic coil is energized to attract the slide rod, lock the lock knob, lock the locking/unlocking, and maintain the locked state by de-energizing the rod. By energizing the former electromagnetic coil to the opposite polarity, the slide rod is pushed out and the lock knob and lock/unlock are unlocked.These operations can be performed remotely using a switch in the driver's seat. The lock knob can be operated independently from the seat, and technical measures have been taken to ensure that there is no interference with the key cylinder operation.

<Example> Next, an example of this invention will be described below with reference to FIG. 1 and the drawings from FIG. 3 onwards.

Note that the same parts as in FIGS. 1 and 2 will be described using the same reference numerals.

In the embodiment shown in FIGS. 3, 4, and 5, reference numeral 19 denotes a locking/unlocking operation device which forms the center of the gist of this invention, and an electromagnetic device 20 provided on the body 2 side of the automobile 1.
The pin 2 is connected to the slide rod 21 made of a magnetic material such as iron and the lock knob 16 described in FIG.
The rod 24 is also made of a magnetic material such as iron and is connected to the link 23 through the rod 2.
The slide rod 21 is detachably brought into contact with the slide rod 21 at the end of the slide door 4, as will be described below.

Then, in the embodiment shown in FIG.
Pin 1 that can be freely engaged and detached from the lock knob 16 that is linked to 3.
Link 12 pivoting to 1 and link rod 1
key cylinder 17 via 8, inner and outer handle 14 via sub-rod 13 linked to link 12, and striker 7 via rod 10.
The claws 8, 9, etc. of the lock/unlock 6 are substantially the same as those of the prior art shown in FIG.

Therefore, this invention can partially use the technology of the conventional aspect as it is.

As shown in detail in FIG. 4, the main part of this invention is shown in detail in FIG. An electromagnetic coil 26 is provided between the flanges 27, 27, and a slide rod 21 made of a magnetic material such as iron is inserted so as to be able to move forward and backward, and a flange 28 is provided at one end as a stopper, and the other A compression spring 30 having a spring constant sufficiently weaker than the resistance force for unlocking is interposed between the flanges 29 and 27.

In addition, another electromagnetic coil 3 is attached to the slide rod 21.
1 is wound around the slide rod 21 so that the slide rod 21 itself is magnetized, and the electromagnetic coil 2
6 and is connected to a predetermined relay 32 having an appropriate delay circuit that is energized after a set time delay, and the relay 32 is connected to the power source 3 via a switch 33 in the driver's seat.
Connected to 4.

In the above-mentioned configuration, when the driver confirms that the sliding door 4 is in the closed state in the unlocked state shown in FIG. First, the electromagnetic coil 31 is excited via the relay 32,
The slide rod 21 is magnetized, and its end face is magnetically attached to the end face of the rod 24 so that the relay 32
As shown in FIGS. 5 and 6, the electromagnetic coil 26 is also energized after a predetermined period of time via the delay circuit in the slide rod 21, and the slide rod 21 is pulled to the left in the figure.
As a result, the rod 24 is also pulled together, the lock knob 16 is lowered via the link 23, and the lock/unlock 6 is placed in the locked state.

This process is illustrated by lock operation R in FIG.

When the switch 33 enters the neutral non-conducting state, both the electromagnetic coils 26 and 31 become de-energized, but since the elastic spring 30 is sufficiently weaker than the resistance force for unlocking as described above, it is difficult to apply the unlocking force. The lock condition is therefore maintained.

To move on to the unlocking UR process shown in FIG. The coil 31 is de-energized, the slide rod 21 is returned to the direction of the sliding door 4, the rod 24 is also returned, the lock knob 16 is raised, and the lock knob 16 is in the unlocked state.
The lock on the lock/unlock 6 is released by the operation,
The sliding door 4 is opened.

Then, locking from the driver's seat by closing the next door is performed as described above.

In the embodiment shown in FIGS. 3 to 6, when the sliding door 4 is opened and closed in the unlocked state, the electromagnetic coil 26 is in a non-energized state, so the flange 28 as a stopper comes into contact with the flange 27. Therefore, in the case where the tip of the slide rod 21 protrudes toward the opening/closing end of the door and obstructs the entry and exit of the occupant, the embodiments shown in FIGS. 7 to 9 may be considered.

That is, a pair of electromagnetic coils 26 and a trigger electromagnetic coil 26' for the sliding door 4 side are installed in the casing 25 of the electromagnetic device 20', and the slide rod 21 into which the two electromagnetic coils 26, 26' are loosely inserted has the other side. The electromagnetic coil 31 is wound around the electromagnetic coil 2.
The slide rod 21 has flanges 28 and 29 interposed with neutral elastic springs 30 and 30' on both ends of the rod 6.
As shown in Figure 9, the relay 32' is
With the lock terminal side of the switch 33' connected to ON, first, start with the electromagnetic coil 2 for the trigger.
6' is energized, and the slide rod 21, which had not been protruding from the opposite side of the slide door 4 of the body 2, is made to protrude as shown by the dotted line in FIG. 7 and comes into contact with the tip of the rod 24 on the side of the slide door 4. ,
After that, other electromagnetic coils 3 through the design time delay.
1 is energized, slide rod 21 and rod 2
4 are magnetized and integrated, and one of the electromagnetic coils 26 is energized by a design time delay operation to pull the slide rod 21 to the left in the diagram, and the rod 24 is also pulled together to bring it into the locked state. The delay circuit is designed to have a suitable delay circuit.

Note that the polarity between them is determined by design.

As in the previous embodiment, the locked state is maintained even in the non-energized state, and the elastic springs 30, 30' have a smaller return force than the unlocking resistance and are not unlocked.

When the driver turns the switch 33' to the UR side for unlocking, the trigger electromagnetic coil 26' and other electromagnetic coils 31 are de-energized, as shown in FIG. One of the electromagnetic coils 26 is excited to the opposite polarity, and the slide rod 21 is pushed to the right in the drawing, pushing the rod 24 and raising the lock knob 16 to the unlocked state.

Then, when the switch 33' is turned OFF and the power is not energized, the slide rod 21 becomes free and returns to the neutral position by the operation of the compression springs 30 and 30'. It recedes into the interior and does not pose any hindrance to passengers entering and exiting through the door opening.

It goes without saying that the embodiments of this invention are not limited to the above-mentioned embodiments, and various embodiments may be adopted, such as interposing a thin cushioning rubber or the like on the opposite end of the slide rod to muffle noise and prevent wear. It is possible.

<Effects of the invention> As described above, according to this invention, electromagnetic operation from the driver's seat can be performed to lock/unlock the sliding door that is opened and closed along the guide rail installed horizontally on the side of the vehicle body of a van-type vehicle, etc. In the device, a slide rod made of a magnetic material is provided on the body side and is coaxial with the tip of the rod made of a magnetic material linked to a lock knob linked to locking/unlocking the sliding door, and is made of a magnetic material that comes into contact with and separates from the tip of the rod. By inserting one electromagnetic coil through the slide rod and wrapping it with another electromagnetic coil that excites the slide rod itself, the rod and slide rod are linked together in such a way that the lock knob basically locks and unlocks the slide door. Rather than mechanical engagement or locking, we use magnetic engagement and demagnetization to connect and release the locks, so when locking and unlocking operations, the locks and the locks only need to be connected and separated directly. The excellent effects are that there are few moving parts, good transmission efficiency, no wear or looseness, and the initial assembly accuracy can be maintained.

Since the electromagnetic coil is provided on the body side, this makes it easy to install and wire the circuit relay, and the structure is simple, easy to manufacture and manage, and can be manufactured at low cost. There are some effects that can be done.

In addition, the slide rod can be excited by winding another electromagnetic coil around the slide rod itself.
It is easy to wrap and assemble, and it also has the effect that it can be reliably engaged and disengaged from the rod on the sliding door side.
