Description

[Detailed description of the invention] TECHNICAL FIELD The present invention relates to improvements in automobile doors.

For example, when opening and closing a car door to get in and out of a crowded parking lot, etc., if you are not careful about the opening degree of the door, there is a risk that it will hit an adjacent car and cause damage.

(1983-10043'2, etc.), the lock was not secure and the door would open unexpectedly if a foot or hand hit it. Also,
Since the number of engagement grooves is limited, it has not been possible to lock the opening at an arbitrary degree.

The present invention has been made in view of the above-mentioned conventional problems.
An electromagnetic device for locking the door at an arbitrary angle and a control circuit having a switch for controlling the operation of the electromagnetic device are provided,
The door can be reliably locked at any angle only when the lock is operated by a switch, and the door can be smoothly opened and closed to allow safe boarding and alighting.

Embodiments of the invention will now be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the door 3 that opens and closes the side opening 2 of the vehicle body 1 is 1. The inner end surface 5 of the outer panel 4 of the vehicle body 1 and the front end surface 7 of the inner panel 6 of the door 3 are attached via hinges 8, 8 so as to be freely openable and closable outward.

As shown in FIG. 2, a bracket 9 is fixed to the opening surface 5 of the vehicle body 1, and the front end surface 7 of the door 3 is attached to the bracket 9.
An engaging member 11 extending into the door 3 through a slit hole 10 formed in the door 3 is attached by a pin 12 so as to be rotatable in a horizontal plane. A sawtooth portion 11a with a fine pitch is formed on the outer edge of the locking member 11.

On the other hand, on the inside of the door 3, near the front end surface 7, there is a rising edge 13a that guides the locking member 11 by abutting the inner edge of the locking member 11.
A substrate 13 having an electromagnetic device 14 is provided on the substrate 13.
The solenoid 15 is fixed, and the serrated portion 1 of the arrangement locking member 11 is
1a and a retaining portion 16a that is removable from the plunger 1a, a collar portion 16b is provided at the other end of the plunger 16, and a coil spring 17 is compressed between the collar portion 16b and the base plate 13,
The coil spring 17 causes the plunger 16 to be connected to the engaging portion 16.
a urges the locking member 11 in the direction of detachment from the sawtooth portion 11a.

The solenoid 15 is connected to a switch circuit 1 consisting of a first changeover switch 19a provided on the armrest 18 of the door 3 and a second changeover switch 19b provided on the rear end surface 20 of the door 3.
9 to the power supply 21.

In addition, 22 is a steering handle, 23 is a front window, 24 is one door window, 25 is an inner handle of door 3, 26 is a door lock hook that fixes door 3 in the fully closed position, 27 is an inner panel of vehicle body 1, 28 is an outer panel of the door 3.

With the above configuration, when the door 3 is opened using the inner handle 25 to an arbitrary opening degree that does not hit an adjacent vehicle, the locking member 1.1 is moved inside the door 3 as shown in FIG. When the plunger 16 is pulled out and the first switch 19a is switched, the solenoid 15 is energized and the collar 16b of the plunger 16 is attracted, and the engaging portion 1 of the plunger 16 is pulled out.
6a engages with the sawtooth portion 11a of the locking member 11.

Therefore, in this state, the door 3 is locked and cannot be opened or closed, and even if a foot or hand hits the door 3 when getting on or off the vehicle, there is no risk of it opening unexpectedly.

Next, to close the door 3 after getting off the vehicle, switch the second switch 19b, the solenoid 15 is demagnetized, the plunger 16 is returned by the biasing force of the coil spring 17, the lock is released, and the door 3 is closed. It becomes like this.

In the above configuration, during the opening/closing operation of the door 3, the locking member 11
Since the engaging portion 16a of the plunger 16 does not come into contact with the sawtooth portion 11a of the plunger 16, there is no resistance to the opening/closing operation.

Further, since the sawtooth portions 11a of the locking member 11 can be formed with a fine pitch, the door 3 can be locked at any angle.

In the above embodiment, the opening degree of the door 3 is locked and unlocked using the 19'' changeover switch 19a operated inside the vehicle and the 2nd changeover switch 19b operated outside the vehicle. Switches 19C and 19d linked to the handle 25 and the outer handle (not shown) close the door 3.
It is also possible to configure the opening degree to be locked and unlocked.

That is, as shown in FIGS. 4 and 5, sawtooth portions 11a are formed on the upper surface of the retaining member 11 of the bracket 9, and on the other hand, both side edges of the locking member 11 are formed near the front end surface 7 inside the door 3. A retaining part 16a is provided at one end of the holder 29 having 29a and 29a, and a coil spring 17 is compressed between the engaging part 16a and the holder 29. The coil spring 17 causes the engagement portion 16a of the plunger 16 to engage the sawtooth portion 11a of the locking member 11.
bias in the direction of engagement.

The solenoid 15 is a switch formed by connecting in parallel a switch 19C that is turned on when the inner handle 25 is operated to unlock the door, and a switch 19d that is turned on when the outer handle is operated and the door is unlocked. It is connected to a power source 21 via a circuit 19 .

With the above configuration, when the inner handle 25 is pulled in an attempt to exit the vehicle, the door lock is released, the switch 19C is turned on at the same time, the solenoid 15 is energized, the plunger 16 is attracted, and the plunger 16 is engaged. The portion 16a is detached from the sawtooth portion 11a of the locking member 11.

In this state, after opening the door 3 to the desired opening degree, when you release your hand from the inner handle 25, the return operation of the inner handle 25 turns off the switch 19C, demagnetizes the solenoid 15, and pushes the plunger 16 into the coil spring 1). It returns with the urging force of 7, and the engaging portion 16a engages the sawtooth portion 11a of the locking member 11.
engage with.

Ru.

Next, to close the door 3 after getting off the vehicle, pull the outer handle, the switch 19d is turned on, the solenoid 15 is energized again, the plunger 16 is attracted, and the engaging portion 16a of the plunger 16 is engaged. The stop member 11 is detached from the sawtooth portion 11a, and the opening lock is released.

In this state, when the door 3 is closed and the outer handle is released, the switch 19d is turned off by the return operation of the outer handle, the solenoid 15 is demagnetized, and the plunger 16 is turned off.
is returned by the biasing force of the coil spring 17, and the engaging portion 16a comes to engage with the sawtooth portion 11a of the locking member 11.

As is clear from the above description, the present invention includes an electromagnetic device that locks the door at any angle, and a control circuit that has a switch that controls the operation of the device. This allows the door to be reliably locked at any angle using an electromagnetic device, preventing the door from opening unexpectedly even if one's hand touches the door, and eliminating the risk of damage from being hit by a neighboring car or the like.

Further, since the electromagnetic device does not affect the opening/closing force of the door, the opening/closing operation can be performed smoothly, and a wide range of opening locking stages can be set, so that the door can be locked at any opening.
