Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a power supply device for electrically connecting electrical devices on the body side of an automobile and a sliding door, for example, and in particular, the present invention relates to a power supply device for electrically connecting electrical devices on the body side of an automobile and a sliding door. The present invention relates to a power supply device capable of detecting an intermediate position before reaching a fully closed state, that is, a half-latched position in a door lock.

[Conventional technology]

For sliding doors, where the entire door slides relative to the vehicle body, electrical devices such as actuators installed on the sliding door side and the power source (battery) on the vehicle body side can be connected with just a conductor. It is not possible to connect.

Therefore, for example, as disclosed in Japanese Utility Model Application Publication No. 61-87416, a power supply device with movable contacts that can be retracted and retracted is installed on the vehicle body side and the sliding door side, and these contacts come into contact with each other when the door is closed. With this, power is supplied from the vehicle body side to the door side.

In general, a sliding door is closed in a different direction from the direction in which the door closes and the direction in which the striker enters the door lock device, and is heavy, so the door lock is often in a half-latched position and the door is closed in a so-called half-closed state. In order to prevent this, the door must be closed with a large force or inertial force, which places a heavy burden on the elderly and children.

To solve this problem, various devices have been proposed that automatically change the door lock to the full latch position when the door lock is in the half-latched position, thereby completely closing the door.

For such devices, it is necessary to use a detector or the like to detect whether the door is in the ajar state. Conventionally, this detector was installed in the door lock device to directly control the rotation of the latch. It was beginning to be detected.

[Problem that the invention seeks to solve]

In the case of detecting the rotation of the latch as described above, a detector must be installed separately in a position close to the latch, so it is necessary to provide a space around the latch in the door lock body to install the detector. , and the door lock device becomes larger.

Further, the structure of the door lock device becomes complicated, which reduces assembly workability and work efficiency, and also causes problems such as the wire harness and power supply circuit for supplying power to the detector become complicated.

The present invention aims to solve the above-mentioned problems by providing a power supply device with a detector for detecting the half-latched position of the door lock device.

[Means for solving problems]

A means for solving the above problem is to move one of a pair of power supply connectors, which are provided on the base so as to be freely retractable and have a moving shaft biased in a direction in which the contact at the tip protrudes, toward the vehicle body, and In a power supply device in which contacts are provided opposite to each other on the other opening/closing body side, when the opening/closing body is closed,
A detector is attached to the power supply connector on the switching body side to detect a predetermined intermediate position after the contacts come into electrical contact with each other until the switching body is in a completely closed state. .

[Effect]

As the opening/closing body moves from the open door state to the closing door side, the contacts on the moving shafts of the power supply connectors provided on the vehicle body side and the opening/closing body side first come into contact with each other, and power supply to the opening/closing body side is started. From this state, when the opening/closing body is further closed and reaches a predetermined intermediate position before reaching the fully closed state, a detector installed in the power supply connector on the opening/closing body side is activated to detect, for example, the half-latched position of the door lock device. be able to.

The respective strokes (n) and (m) of the moving axis 31 and the moving axis 13 on the sliding door 1 side are set approximately equal, and the sum of both is the movement of the sliding door 1 from the ajar state to the fully closed state. than the range,
I've made it bigger.

The moving shafts 13 and 31 move in and out almost evenly because the spring constants of the compression coil springs 18 and 33 contracted on both of them are the same.

A conductive wire 35 is connected to the front end of the vertical moving shaft 31, and one of these two conductive wires 35 is connected to the vehicle body 2.
One side is electrically connected to a controller 36, and the other side is electrically connected to a battery 37 (see FIG. 2).

Next, the operation of the above embodiment will be explained with reference to the circuit diagrams of FIGS. 4 to 8 and 9.

When you close the sliding door 1, first the car body 2
The power supply switch 6 installed near the center pillar 2a is automatically turned on by the sliding door 1, and the contact (R _1-1 ) of the relay R ₁ in the controller 36 is closed, so that the power supply switch 6 is automatically turned on from the battery 37 to the vehicle body 2 side. The power supply connector 9 is energized.

In this state, if door 1 is further closed,
As shown in Figure 6, just before the half latch,
The contact 13a of the moving shaft 13 in the power supply connector 8 on the door 1 side contacts the contact 31a of the moving shaft 31 on the power supply connector 9 on the vehicle body 2 side, and at that moment, power is supplied from the vehicle body 2 side to the sliding door 1 side. The vehicle body 2 and the electric device on the door 1 side are electrically connected.

When the door 1 is further slightly closed from the state in which the contacts 13a and 31a are in contact with each other, the latch 38 in the door lock device 3 and the striker (S) on the vehicle body side
When the latch 38 begins to engage and the latch 38 reaches the half-latched position as shown in FIG. When the rear end of the door 13 comes into contact with the movable contact 24 of the detection switch 20, they are electrically connected to each other, and a detection signal indicating that the door is half-latched is immediately sent to the controller 5 provided on the door 1.

If _the sliding _door 1 remains in the half-latched state and cannot be closed any further, the relay (R ₃ )
The motor 39 in the closure 4 is energized and the movable contact (R _3-1 ) is operated to the normally open side.
is rotated in one direction.

The rotation of the motor 39 causes the drive gear 40 to rotate clockwise in FIG. It is rotated counterclockwise towards the position.

When the sector gear 41 rotates, the drive lever 43, which rotates together with the sector gear 41, rotates the close lever 45, which is pivotally connected to the bracket 44 of the door lock device 3, in a counterclockwise direction in a plan view using a wire 46. make it move.

This causes latch 3 in the half-latched position.
8 is a protruding lever 4 protruding from this latch 38.
7 engages with one arm 45a of the close lever 45 and is forcibly rotated to the full latch position as shown by the two-dot chain line in FIG. The sliding door 1, which was locked at the end and was in the ajar state, is completely closed.

When the latch 38 is fully latched, the other arm portion 45b of the close lever 46 moves toward the bracket 44.
It closes when it comes into contact with the full latch switch 48 provided above, and when the relay (R ₂ ) is energized, the contact (R 2 ) that was normally closed until then is closed.
2 _-1 ) operates to the normally open side and is self-maintained, and at the same time, the contact (R _3-1 ) of the relay (R ₃ ) returns to the normally closed side to stop the motor 39.

Also, at this time, the normally open contact of the limit switch 49 provided at the rear of the sector gear 41 is closed by the rotation of the sector gear 41, so the movable contact (R _4-1 ) of the relay (R ₄ ) is normally open. motor 39 rotates in the opposite direction. As a result, the sector gear 41 is rotated clockwise and returned to the neutral position, and at the same time, the limit switch 49 is turned OFF.
The movable contact (R _4-1 ) in the relay (R ₄ ) returns to the normally closed state, and the motor 39 immediately stops.

When the sector gear 41 returns to the neutral position, the close lever 46 is rotated clockwise in plan view by the return spring 50, and the engagement state of the latch 38 with the protruding lever 47 is released. This does not impede the rotation of the latch 38 when the door is opened.

Note that when the sliding door 1 is completely closed without passing through the ajar state and the latch 38 in the door lock device 3 is in the full latch position, the moving axes 13 and 31 of each power supply connector 8 and 9 are moved to the eighth position.
Predetermined stroke (m)(n) as shown in the figure
The movable contact 24 of the detection switch 20 is forcibly moved backward with the lower moving shaft 13 in an electrically conductive state.

In this case, each device such as the closure 4 is designed to perform a series of operations in the same manner as described above, in consideration of the case where the latch 38 does not reach the fully latched position and stops midway. is securely in the fully latch position, close lever 4
5 only rotates idly.

Next, a second embodiment of the present invention will be described with reference to FIGS. 10 and 11.

This embodiment basically has the same configuration as the first embodiment described above, so common members will be described with the same reference numerals, and detailed explanations thereof will be omitted. Only the differences will be briefly explained.

In the base 52 of the power supply connector 51 on the side of the sliding door 1, four moving shafts 13 similar to those described above are fitted vertically in parallel and retractable, the two in the center are for power supply, and the other two are for power supply. One of them (the lower one in this embodiment) operates as a half latch detection switch 20.

Note that the reason why two moving shafts 13 for half-latching detection are provided, one above the other, is to allow the power supply connector 51 to be used in common due to differences in attachment.

The moving shaft 13 serving as the half latch detection switch 20 is electrically connected to the controller 5 through a conductive wire (not shown).

Base 5 in power supply connector 53 on vehicle body 2 side
4, a moving shaft 31 that can come into contact with the two central moving shafts 13 is fitted and retractably inserted.

Conductive fixed contacts 55 are attached to the upper and lower sides of the mounting piece 54a connected to the base 54, and are adapted to come into contact with the vertical movement shaft 13 of the power supply connector 51 on the door 1 side.

The lower contact point 55 is connected to the controller 36 on the vehicle body 2 side through a conductive wire 56.

When the sliding door 1 is closed, the two central moving shafts 13 and 31 first come into contact with each other in front of the half latch, and power supply from the vehicle body side to the door side is started. When the door 1 is further closed from this state to the half-latched position, that is, the half-door state, both moving axes 1
3 and 31 are immersed almost equally in the required amount,
The tip of the lower moving shaft 13 serving as the half latch detection switch 20 comes into contact with the fixed contact 55 (see FIG. 11), and a half latch signal is immediately issued to the controller 5.

Thus, similar to the first embodiment described above, the closure 4 is operated by a circuit not shown, and the latch 38 in the door lock device 3 is forcibly rotated from the half-latched position to the full-latched position.

As described above, in the first and second embodiments, if the sliding door 1 is closed to the half-latched position (ajar state), it can be automatically set to the full-latched position (fully closed), so especially It can be easily operated when closing from the indoor side or when closing on a slope.

In addition, a detection switch 20 for detecting the half-latched position is provided on the power supply device, and a simple detection method using the protrusion and retraction of the moving shafts 13 and 31 is used, so that it can be easily detected without making major design changes to the conventional power supply device. Moreover, since there is no need to provide a detection switch on the door lock device side, the structure of the conventional door lock device does not become complicated.

A power supply switch 6 starts supplying power to the vehicle body 2 a little before the sliding door 1 reaches the half-latched position.
By providing the contact point 31a of the power supply connector 9 of the vehicle body 2, there is no fear that a metal object will hit the contact point 31a and shoot out, resulting in high safety.

Note that the present invention is not limited to the above-mentioned embodiments, and can take various embodiments.

For example, in the first embodiment, the retractable movable contact 24 is used for the half latch detection switch 20, but instead of this, a micro switch, a proximity switch, a photo sensor, etc. etc. can also be used.

Further, the spring constants of the compression coil springs 18 and 33 may be changed as appropriate to give order to the movement of the moving shafts 13 and 31.

It goes without saying that the present invention can be applied to back doors, side doors, trunk lids, etc. in addition to the above-mentioned sliding doors.

〔Effect of the invention〕

According to the present invention, a detector for detecting a predetermined intermediate position before the opening/closing body enters the fully closed state is provided in the power supply connector on the opening/closing body side, so that it is possible to detect, for example, the half-latched position of the door lock device. It is no longer necessary to provide a detector in the door lock device as in the conventional case, and there is no fear that the door lock device will become large or complicated in structure.

Further, the present invention can be implemented at low cost without making any major design changes to the conventional power supply device.
