Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an automobile door lock device, and particularly to an improvement in its striker structure.

<Conventional technology> In order to prevent the intrusion of rainwater, etc., a sealing member called a weather strip made of synthetic rubber is installed in the gap between the door and the vehicle body. In order to avoid wind noise and wind leakage noise, there is a tendency to use weather strips made of materials with relatively high pressing reaction force. Therefore, when the door is closed, this pressing reaction force prevents the door from being completely locked, increasing the risk of the door being left ajar. In order to obtain a completely locked state, it is necessary to close the door with strong force to overcome the reaction force of the weather strip, which is inconvenient.Also, if the door is closed suddenly, it may cause noise and damage to the vehicle. Occupants may feel uncomfortable due to changes in indoor air pressure.

<Problems to be Solved by the Invention> In view of the problems of the prior art, the main object of the present invention is to provide a door lock for an automobile that can securely lock the door without requiring excessive closing force. The object of the present invention is to provide a striker structure in a device.

Means for Solving the Problems> According to the present invention, this object includes a lock member mounted on the door side and a striker provided on the vehicle body side so as to be engageable with the lock member. A striker structure in an automobile door lock device, wherein the striker is movable along the closing direction of the door, and when the locking member engages with the striker, the striker is moved l! This is achieved by providing a striker structure in a door lock device for an automobile, characterized in that it is provided with means for moving the door in the f1 door direction.

<Function> In this way, by making the striker provided on the vehicle body side to engage with the locking member on the vehicle door side driveable in the door closing direction by external power, etc., the weather strip is deformed by pressure. It is possible to completely engage the locking member with the striker and then retract the striker toward the interior of the vehicle using power or the like to achieve complete rfIti, thereby making it possible to close the door with a relatively small operating force.

<Embodiments> Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

In FIG. 1, a locking device 4 is attached to a space inside the door defined inside a door rear end surface 6 formed by bending the door inner panel 1a toward the door outer panel 1b, and A U-shaped striker 5 is provided on the front end surface 8 of the center pillar or rear pillar, which is a part of the
is attached via a base plate 9. A weather strip 2 is attached to a corner of the rear end face 6 of the door, and when the door is closed, the weather strip 2 comes into elastic contact with the body outer panel 3 to provide the required sealing effect.

A boss 5a having a rectangular cross section is provided at the base 5b of the striker 5.
protrudes toward the vehicle body and enters a horizontally elongated rectangular guide hole 9a bored approximately in the center of the base plate 9. Roughly, left and right edges 10b of rectangular plate material
A cam follower 10 is bent toward the vehicle body to define a rectangular recess 10a, and a boss 5a projects through the guide hole 9a of the base plate 9 toward the inside of the front end surface 8 on the vehicle body side.
It is fixed to the roadside with a countersunk bolt 14. the result,
The cam follower 10 and the striker 5 are prevented from being removed in the front-back direction by the base plate 9, and are allowed to move integrally in the left-right direction within a range until the boss 5a abuts the left and right ends of the guide hole 9a. There is. Furthermore, a sealing member 7 made of a synthetic resin with a relatively low coefficient of friction, which may be a fluororesin-based material, is sandwiched between the base plate 9 and the base portion 5b of the striker to prevent dust and water droplets from entering the inside of the body panel. At the same time, this has the effect of reducing the frictional resistance when the striker 5 slides in the horizontal direction.

The cam follower 10 defines a pair of inner wall surfaces rising in a direction perpendicular to the sliding direction by its left and right edges 10b in order to receive a cam to be described later. A lining 17 made of synthetic resin is attached.

Further, the motor 16 with a speed reducer is attached to the inside of the body outer panel 3 via a bracket 15 with bolts (not shown) so that its drive shaft 12 faces forward. At the roadside of the drive shaft 12, there is a cam 11.
are integrally fixed with set screws 13, and the cam is received in the recess 10a of the cam follower 10. The cam 11, as clearly shown in FIGS. 2a and 2b, has a heart shape in which the long axes of two oval cams are overlapped at right angles.

When assembling such a structure, first, the motor 16 with a reduction gear is attached to the bracket 15, and then the cam 11 is attached to the drive shaft 12 that protrudes through the bracket by setting the screw 1.
3, and then the striker 5 and cam follower 10 are fixed with countersunk bolts 14 so as to sandwich the base plate 9 therebetween. Then, with the cam follower 10 and the cam 11 engaged, the bracket 15 is screwed onto the base plate 9 using bolts (not shown), and this is attached to the front end face 8 of the pillar with the base plate 9 as one assembly. In this way, the motor 16 with a reducer to which the cam portion is attached is inserted into the body panel defined by the body outer panel 3 and the body inner panel 19 through the window 8a provided in the front end face 8 of the pillar, and Only the pace plate 9 and striker 5 will be exposed. Note that the reference numeral 18 is a lead wire for supplying power to the motor.

Next, the operation of the above embodiment will be explained.

First, when the door is opened, the cam is oriented so that the striker 5 is located on the right side in FIG. 1, that is, on the outside of the vehicle body (FIG. 2a). If you close the door from this state,
Since the striker 5 is located on the outside, the locking device 4 and the striker 5 engage with each other before the weather strip 2 provided on the door side is pressed and deformed, and the locking device 4 is completely locked. In this state, the weather strip is merely in contact with the vehicle body, and the airtightness of the interior of the vehicle may still be insufficient. Furthermore, there is a gap between the door outer panel 1b and the body outer panel 3 as indicated by Δ (dimension), and although the door appears to be in a half-closed state, it is in a completely locked state, and there is a gap between the door outer panel 1b and the body outer panel 3. Since this is before a large amount of force is exerted, the operating force required to close the door in this manner is extremely small.

When the completion of locking is detected by, for example, a limit switch (not shown) and a driving command is given to the motor 16 with a reduction gear, the cam 11 is rotated in the direction shown by the arrow 8 in FIG. 2a, and the rotation of this cam Accordingly, the striker 5 along with the cam follower 10 moves along the guide hole 9a in the direction indicated by the arrow A in FIG.
It is forcibly slid in the direction shown by , that is, toward the interior of the vehicle. When the limit switch detects the completion of the striker's sliding or the completion of the cam's rotation and stops the motor, the door will be retracted to the position shown by reference numeral 1' in Fig. 1, and the weather strip 2 will also be fully retracted. It deforms under pressure and a sealed state is obtained.

Next, when the door is opened, the limit switch detects the opening, and the cam 11 rotates in the direction shown by arrow C in FIG. will be realized.

Although a general hinge type automobile door has been described above, the present invention can also be suitably implemented in the case of a sliding door. FIG. 3 shows an embodiment of the present invention for a sliding door.

In FIG. 3, parts that are the same as or correspond to those in FIG. 1 are given the same reference numerals.

While a hinged door moves in an arc around the hinge axis, a sliding door moves in parallel to the left and right of the vehicle body.
The door is opened and closed by a combination of back and forth movement along the vehicle body, that is, the door is opened and closed by sliding along a guide rail provided on the vehicle body side. In the case of the sliding door in Fig. 3, the entire door is moved diagonally rearward in parallel to a position where the door inner panel 1a and the body outer panel 3 do not interfere with each other, and then the door is slid rearward along the body outer panel. This configuration allows the door to be opened by opening the door. Therefore, the rear end surface 6 of the door and the front end surface 8 of the pillar form an inclined surface in the longitudinal direction, but the door can be closed by engagement between the locking device 4 provided inside the door and the striker 5 provided on the vehicle body side. It is exactly the same as a hinged door in terms of obtaining retention.

Therefore, it is sufficient to arrange the device along the direction of movement of the door indicated by the arrow in FIG. 3, and to use the same assembly as shown in FIG. 2 without making any substantial changes. be able to.

Further, the method of sliding the striker is not limited to the above-mentioned embodiment, and various modes are possible, and the drive means for the striker is not limited to the electric motor, but other means may also be used. Further, the timing for moving the striker to the outside position does not necessarily have to be when the door is opened, and various types of control can be performed as necessary.

<Effects of the Invention> As described above, according to the present invention, the door can be completely locked before the weather strip is completely deformed by pressure, so it is possible to close the door with an extremely light operating force, which improves usability. can have the effect of improving In addition, incomplete rf1m due to the pressure reaction force of the weather strip does not occur, and in addition, due to the structure, half lock (
The so-called half door! 8i) can be reduced.
