Description

Detailed Description of the Invention (Industrial Application Field) The present invention stores operating force when opening a car door and uses that energy to rotate a latch in a door lock when closing the door. This invention relates to a method and device for use as an auxiliary force.

(Prior Art) In conventional automobile doors, a striker provided on either the vehicle body or the door moves from a half-latched position, where it barely engages the latch of a door lock provided on the other side, to a fully engaged position. Until the door reaches the fully latched position where it engages, the reaction force of the weather strip and the reaction forces of various springs inside the door lock act on the door, so you must close the door forcefully or press it forcefully. However, the door could not be completely closed, and when doing so, a loud closing sound was generated, and a large impact was applied to the door and the vehicle body, which had an adverse effect on the door and vehicle body.

Therefore, when the latch reaches the half latch position when closing the door, the latch is forcibly rotated to the full latch position by a drive means such as a motor installed inside the door, making it easier to close the door. However, such devices require a driving means such as a motor and have a complicated structure. However, it also had drawbacks such as being heavy and expensive.

(Object of the Invention) In view of the above-mentioned drawbacks of the conventional device, the present invention provides a method for easily closing a door from a half-latched state to a fully-latched state without providing any driving means such as a motor. The purpose is to

(Structure of the Invention) The method of the present invention temporarily stores the energy generated when the door is opened in a financial device installed at a suitable location, and transfers the energy from the half-latched state when the door is closed. The above object is achieved by using the latch as an auxiliary force for turning the latch when moving to the fully latched state.

The present invention also relates to a device that is directly used to carry out the invention of the method of utilizing the opening operation force in an automobile door.

The latch moves from a half-latch position, where the striker provided on either the vehicle body or the door barely engages with the latch of the door lock provided on the other side, to a full-latch position, where the latch and the striker completely engage. A device for utilizing door-opening force in an automobile door that can completely close the door by rotating the door, the device comprising:
A finance device that is provided on a door or a vehicle body and includes an elastic body for finance, an input member that tensions or compresses the elastic body, and an output member that transmits the repulsive force of the elastic body to the outside.

an input device that is provided between a door and a vehicle body, is connected to an input member of the finance device, and moves the input member in a direction that tensions or compresses an elastic body in conjunction with the opening operation of the door; , a linking device linking the output member and the latch, and a linking device provided between the output member and the latch, and normally disconnecting the output member and the latch to restrain the output member; The present invention is characterized by comprising an interrupting device that detects that the latch has reached a half-latched position, releases the restraint of the output member, and connects the output member and the launch.

(Effects of the Invention) According to the present invention, when the door is opened to a certain extent and then closed to the half-latched state, the energy accumulated during the opening operation of the door causes the latch to rotate in the direction of full latch. Since dynamic assisting force is applied, the door can close by itself or with light effort from the half-latched state to the fully-latched state, making door closing operations much easier than conventional ones. Since the energy generated during the door opening operation is used without using a driving means such as a motor, it is possible to save energy, and it can be manufactured at a lower cost than those using a driving means such as a motor. Moreover, it is possible to achieve effects such as being able to reduce the size and weight.

(50) and can rotate around the axis (46).

A stepped portion (51c) is formed on the peripheral edge of the rotating plate (51) on the opposite side to the wire guide portion (51a), and this stepped portion (51c) has a base attached to the lower part of the main body (43). (5
The hook portion (57a) at the tip of the locking lever (57) pivotably mounted with the locking lever (57) can be engaged with the locking lever (57).

This locking lever (57) is operated counterclockwise in FIG. 7, which is the direction in which the hook portion (57a) engages with the step portion (51c), by a coiled spring (58) wound around the shaft (56). It is constantly biased in the direction.

A release lever (59) is located in the middle of the locking lever (57).

The coiled spring (52) is wound around a spring receiver (53) that is caulked and fixed to the front end of the shaft (46), and has one end attached to a rotating plate (
51), and the other end is locked to a pin (63) protruding from the front surface of the main body (43), and the rotating plate (51) , a clockwise return rotation force in FIG. 7 is applied. The return rotational force of the rotating plate (51) due to this coiled spring (52) is as follows:
The tensile force of the tension spring (21) is smaller than the tension force which attempts to rotate the rotating plate (51) via the wire (17).

Release lever (59), locking lever (57), cam plate (5)
0), the mutual relationship between the rotating plate (51) and the latch (44) is such that when the latch (44) reaches the half-latched position from the release position, the protrusion (50a) of the cam plate (50) engages the release lever. Push the tip (59a) of (59) to move the hook part (57a) of the locking lever (57) once to the plate (51).
The tensile force of the wire (17) applied to the rotating plate (51) is applied to the cam plate (50) and the latch (44) via the projection (50b). ) in the fully latched direction, and after the protrusion (50a) passes the tip (59a) of the release lever (59), the hook part of the locking lever (57) (57a) is due to the action of the coiled spring (58),
The protrusion (50a) is pressed against the outer periphery of the rotating plate (51) (see Fig. 10), and when the cam plate (50) rotates clockwise from the state shown in Fig. 10, the protrusion (50a) The relationship is such that when the release lever (59) comes into contact with the tip (59a), only the release lever (59) rotates around the shaft (60) and the locking lever (57) does not move. be.

Thus, the wire (17), the cable conduit (54), the rotating plate (

A linking device (8) is formed to link the 4) with the rotary plate (51), the cam plate (50), and the locking lever (57).

The output member (13) is always closed by the release lever (59) etc.
The output member (13) is disconnected from the latch (44) and
and detects that the latch (44) has reached the half-latched position, releases the restraint of the output member (13), and connects the output member (13) and the latch (44). (7) is formed.

Next, the overall operation of the device of this embodiment will be related to the method of utilizing the opening operation force in an automobile door of the present invention,
I will explain in detail.

When the door (2) is fully closed, the latch (44) is in the fully latched position, as shown in FIG.
Accordingly, the cam plate (50) is located at a position where the protrusion (50a) has passed the tip (59a) of the release lever (59) in the counterclockwise direction, and the hook portion ( 57a) is the step part (51c) of the one-turn plate (51)
, and the counterclockwise rotation of the rotating plate (51) is prevented.

Further, the clockwise rotation of the rotation plate (51) is controlled by the elongated hole (55).
) is prevented by abutting the protruding piece (50b) of the cam plate (50) on the counterclockwise end surface of the cam plate (50).

As shown in FIG. 3, in the finance device (4), as mentioned above, the rotating plate (51) is restrained by the locking lever (57), so that the wire (17) , is restrained in the inoperative position, and the intermediate member (18) is held in the retracted position by the tension of the tension spring (21).

Furthermore, as shown by the solid line in FIG. 2, the link (41) is the deepest in the door (2), so the input member (26) in the financial device (4) is as shown in FIG. Like most regressive.

From this state, when the inside handle or outside handle is operated to remove the ball (45) from the latch (44), the latch (44) rotates from the full latch position to the half latch position to the release position. The striker (49) leaves the latch (44) and the door (2) opens slightly.

When the latch (44) passes through the half-latch position, the protrusion (50a) of the cam plate (50)
However, at this time, the release lever (59) rotates counterclockwise in FIG. 11 around the shaft (60) and escapes, thereby releasing the protrusion (50a).
) is prevented from being transmitted to the locking lever (57).

Therefore, while the latch (44) rotates from the half-latched position to the release position, the rotating plate (51) remains restrained by the locking lever (57). Thus, the situation shown in practice in FIG. 7 is reached.

Since the opening angle of door (2) at this time is small,
The input device (5) and financial resources device (4) hardly change.

When the striker (49) starts to open the door (2) from the state where it is separated from the latch (44), first, in FIG.
the link (41) is relatively pulled out from the door (2);
Accordingly, the wire (32) is pulled, and the input member (26) is advanced in FIG. 3.

As the input member (26) moves forward, the intermediate member (i
a) The swing link (29), the stop lever (34), etc. move forward together with the input member (26) (at this time, the output member (13) is moved forward when the rotating plate (51) is restrained). (Because of this, it is stopped in the inoperative position and does not move forward).

Immediately before the intermediate member (18) reaches the forward position, the projecting piece (18d) first passes the locking piece (23b) of the locking lever (23), and then, as shown in FIG. (3
The locking part (34b) of 4) comes into contact with the front edge of the elongated hole (37) and rotates clockwise in FIG. 4 around the shaft (35), so that the rear end of the input member (26) It comes off from the locking part (34b).

Then, as shown by the solid line in Fig. 5, the swing link (29
) stands up, and the input member (26) moves forward while its rear end rotates upward.

At this time, the intermediate member (18) moves slightly backward, and the locking piece (23b) of the locking lever (23) is attached to the protruding piece (18d).
When engaged, the lever is restrained at a position close to the forward position.

Note that the locking portion (34b) of the locking lever (34) has a long hole (
The timing of contact with the leading edge of 37) is when the door (2) reaches approximately halfway between the fully open position and the fully open position, and only the opening operation of the door (2) in the first half is a financial device. The input member (26) is used to store energy in step (4), and is
) simply floats around.

As shown by the imaginary line in Figure 2, when the door (2) is opened fully or half-open for a while and then begins to close again, the door (2)
until the link (41) reaches the half-open position.
), and as a result, from the state shown by the solid line in FIG. The input member (26) retreats while the end portion rotates downward.

When the door (2) reaches the almost half-open position, the input member (2)
6) The rear end is the stop part (24b) of the locking lever (34)
while tilting the locking part (34) backward.
b) The rear end of the input member (26) is again locked by the locking portion (34b) as shown in phantom lines in FIG.

Further, when the door (2) is closed, the wire (32) relaxes and hangs down as shown imaginatively in FIG.

When the door (2) is further closed and the striker (49) contacts the latch (44) and the latch (44) is rotated to the half-latched position, the cam plate ( The protrusion (50a) of the locking lever (50) pushes the tip (59a) of the release lever (59), and the hook part (57a) of the locking lever (57) is pushed against the step part (51c) of the rotating plate (51). )
Remove from.

Then, the tensile force of the tension spring (21) acting on the rotating plate (51) via the output member (13) and the wire (17) is released, and the rotating plate (51) Rotate counterclockwise.

The counterclockwise rotational force of this rotating plate (51) is
The clockwise end face of the cam plate (50)
0b), the force is transmitted to the cam plate (50), and further transmitted to the latch (44) via the shaft (46) as a rotation assisting force in the direction of full latch.

Therefore, after the door (2) is closed to the half-latched state, the energy stored in the tension spring (21) during the door-opening operation acts on the latch (44) as a rotational assisting force in the direction of full latch. The door (2) then closes by itself or can be closed lightly.

With the release of energy, the output member (13)
From the illustrated state, it gradually moves forward as it is pulled by the tension spring (21).

When the latch (44) reaches the fully latched position, as shown in FIG. 10, the latch (44) is locked by the ball (45) and the door (2) is fully closed.

Further, as shown in FIG. 6, when the latch (44) reaches the fully latched position or rotates slightly beyond the fully latched position, the protrusion (13b) of the output member (13) The locking lever (23) is brought into contact with the protruding piece (23a) and rotated counterclockwise, and the locking piece (23b) of the locking lever (23) is brought into contact with the protruding piece (23a) of the intermediate member (18). Remove from piece (18d).

Then, due to the tensile force of the tension spring (21), the rear end of the arm (18b) of the intermediate member (18) hits the stopper (13a).
The output member (13) and the intermediate member (18)
) is integrated with them, and the swinging ring 7 (29) is integrated with them.
, the locking lever (34), the input member (26), etc. are moved back from the state shown in FIG. 6 by the biasing force of the tension spring (16) and the coil spring (52), and the third
The state shown in the figure is restored.

The other rotating plate (51) independently rotates clockwise from the state shown in FIG. The hook portion (57a) of the stop lever (57) is engaged and returns to the original state as shown in FIG. 11.

By repeating these operations, when opening the door (2), a part of the operating force is stored in the financial device (4), and after closing the door (2) to the half-latched position,
The stored energy is released as an auxiliary force for turning the latch (44) in the fully latched direction, making it easier to close the door (2).

Therefore, in this embodiment, the same effects as described above can be achieved as the effects of the present invention.

In addition, in this embodiment, all other components can be constructed using only mechanical components such as levers and wires, and no electrical components such as motors, electromagnetic devices, or limit switches are used. Therefore, there is no need to take electrical considerations such as energization errors, disconnections, or brazing, and the tube has the advantage of being inexpensive to manufacture.

(Modifications) The present invention is not limited to the above-described embodiments, and can be modified in many ways.

For example, as a member for storing energy in a finance device, a compression spring, a spiral spring, a piston-cylinder device using air pressure, or an elastic body such as rubber may be used.
