The present invention relates to a passenger car door opening and closing device that can automatically open and close the door of a passenger car, and in particular, by smoothing the operation during opening and closing, it not only protects each part but also improves the operation feeling, thereby improving the automatic door opening and closing device. A car door automatic opening and closing device realized.

In general, the door of the passenger car is opened and closed mostly by artificial means, but in recent years, the automatic opening and closing device by the power motor has been altared. That is, the door of a passenger car is comprised with the snow-closing device for retaining this door of the main body of a car, the locking device for locking by a hook part, and the disassembly apparatus using the link etc. for releasing it. More specifically, as shown in FIG. 1, the inner and outer levers and door handles for opening and closing the passenger car doors, and the racks installed between the small motor (1), the speed reducer (2) and the two support pieces (3) for the 12V automatic opening and closing. It consists of (6) and pinion (5).

However, in the conventional passenger car door opening and closing apparatus of such a structure, there are the following problems.

First, there is a tendency that the rack 6 is easily broken due to frequent opening and closing operation, and the device cannot be advanced due to rattling during operation.

That is, as shown in FIG. 7, since only a simple protrusion a is formed at the end of the conventional rack 100, the pinion 5 is directly caught by the protrusion a when the door is opened to the maximum, and thus the operation thereof is performed. When the senses became significantly worse, there was a problem that the frequent contact caused cracks in the protrusions (a) and the central portion (b) and thus could not maintain the last smooth operating feeling.

Second, there is a problem in reducing the lifespan by bringing over the whole part because there is no buffer means.

Third, by using a normal motor as a power source, the operating feeling of opening and closing manually is significantly reduced. In other words, when opening and closing the door manually, a self-resistance is generated by the magnetic force between the rotor and the permanent magnet of the motor, which hinders smooth opening and closing operation.

The present invention has been made in view of the above problems, to provide a device for gently opening and closing the car door.

In addition, a second object is to realize an advanced passenger car door that automatically opens and closes by a series of operations such as operating the unlocking device and delaying motor operation before the door opening operation.

In order to achieve the above object, the present invention, the reducer (2) connected to the motor (1), and the pinion (5) connected to one end of the reducer (2) operates the rack (5) automatically open and close the car door In this case, two support pieces 3 for supporting and fixing the rack 5 and the pinion 6, guide rollers 4 for supporting the rack 6 on the back of the rack 6, and one end Locking release means for releasing the safety locked locking device when the shock absorber 7 and the door 8 installed in the closed state, delay means for delaying the operation of the motor 1 to a predetermined set time, and an example. It consists of a control box 13 composed of a buzzer 15 for sounding a warning sound.

Hereinafter, it will be described in detail based on the accompanying drawings.

In general, the automatic opening and closing device, as shown in Fig. 1 is a geared motor (1: drive motor) with a reduction gear (2) in the interior of the passenger car door (8) and two support pieces (3) on the top thereof It is fixedly installed, and between the support piece (3) is provided with a guide roller (4), pinion (5), rack (6).

In addition, the pinion 5 and the rack 6 are adapted to allow mutual power transfer.

The pinion 5 is connected to the output end of the speed reducer 2, and the guide roller 4 contacts the rear surface of the rack 6 to regulate the unauthorized movement of the rack 6.

One end of the rack 6 is provided with a hole portion 6a so as to be flush with the passenger vehicle body side, and the other end is provided with a buffer port 7 such as a rubber material.

Reference numeral 7 'denotes a buffer port, 7 a fixing pin, 9 a passenger car body, 10 a fixing fixed to the main body 9 side, and 11 a snow shaft.

In addition, an electric actuator 12, which is a release means for releasing locking of the inside of the passenger car 8, and a control box 13 made of a relay 2, a delay circuit 3, and the like are installed. 13 is configured to be connected to the electric actuator L2 and the motor 1 and the remote switch 14 installed in the driver's seat, respectively.

The control box 13 includes a delay means (T: timer) consisting of a resistor R3 and a capacitor C1, diodes D2 and D3 and diodes D4 and D5, transistors TR1 and TR2, and Buzzer 15 and a relay switch RL2 interlocked with the relay L2.

Resistor R1 and R2 and diode D1 are connected to the motor 1.

In particular, since the motor 1 adopts a skew type, it is possible to eliminate the phenomenon of jamming during manual closing.

Next, the operation of the present invention will be described.

First, the door opening operation is to open the passenger car door 8 when the passenger car door 8 is closed, i.e., when the passenger car door 8 is locked to the passenger car body 9 as shown in FIG. When the remote switch 1 is pushed to the " open " side as shown in the block diagram of FIG. 4 and the circuit diagram of FIG. The delay operation delays the operation of the drive motor 1.

This state is explained in more detail.

When the remote switch 1 is pushed to the open side, the primary electric actuator L1 is operated to release the locked state, and a buzzer 15 (example warning sound means) sounds through the diode D2. The buzzer 15 stops ringing by the power inputted through the transistor TR2 and the delay means T, and at the same time, the relay L2 connected in series with the transistor TR1 is excited and the relay switch ( Since the RL2 is closed, the drive motor 1 is driven so that the passenger car door 8 can be opened from the vehicle body 9.

Then, when the drive motor 1 is operated secondarily, the rotation of the drive motor 1 is decelerated in the reducer 2 to rotate the pinion 5 and the pinion 5 is placed on the support piece 3. Since it is engaged with the installed rack (6) it operates and the rack (6) operates while rotating itself around the axis (11) while being supported and guided by the guide roller (4).

This operation, in more detail, applies the operating principle of the rack and pinion.

That is, as shown in Fig. 8, the side A and the shaft 11 are fixed and the pinion 5 is fixed.

In this state (closed state indicated by broken lines), the door 8 is opened by moving in the direction of the arrow, which causes the rack 6 to be linearly moved by the rotational movement of the pinion 5, but one end thereof is Since the shaft 11 is fixed to the shaft 11, the rod 6 rides in the other direction, so that the rack 6 itself rotates about the shaft 11 as the pinion 5 rotates. and The door (8) is opened to expand to.

At this time, the pinion (5) also in the direction of the arrow Compared to Because it becomes It opens at an angle () that corresponds to its length.

In fact, the pinion 5 transmits power, but the rack 6 is held on the fixing piece 10 of the main body 9 by the shaft 11, so that the virtual line of FIG. The door 8 is opened while rotating as indicated by. The pinion 5 operates along the gear teeth of the rack 6, which rotates and pushes the rack 6 and opens as far as it is moved.

One of the main effects of the present invention will be described the buffer and stopper action.

Since the buffer opening 7 is provided at one end of the lacquer 6, the contact portion 7 'of the buffer opening 7 is brought into contact with the one end 3' of the support piece 3 for opening operation. It absorbs the shock and acts as a stopper to regulate the maximum opening angle (see Figure 2).

Therefore, the life of the part is protected even when the protrusion a formed on the rack 6 has a smooth opening operation by eliminating the impact of the pinion 5 contacting as in the related art.

On the other hand, when closing the passenger car door 8 opened as described above, press the remote switch 14 to the "closed" side, and the motor 1 rotates in reverse as opposed to the opening operation described above, thereby executing the closing operation. .

That is, the power drawn into the diode D3 achieves the door lock standby state and causes the buzzer 15 to ring during the delay time of the timer T, which is a delay means, and at the same time, the relay switch interlocking with the relay L2 ( The RL2 is closed and the motor 1 is reversely driven through the transistor TR2 and the diode D5.

In the present embodiment, the buzzer 15, which is an exemplary warning sound device, also sounds during the closing operation.

On the other hand, the power during the opening and closing operations is determined by the synthetic resistance devices such as the resistors R1 and R2 and the diode D1.

For example, the power in the closing operation is set to be larger than the power in the opening operation so that the mistake of the locking operation is reduced and there is no anxiety about the safe locking state.

In the case of abnormal operation power in the inclined position, it is possible to solve the problem by adopting a power adjusting means for generating an arbitrary operating power as much as the inclination angle by using a mercury switch (not shown).

In addition, the present invention operating as described above may be manually operated as necessary, in this case by pushing or pulling the rack 6 by the lever action of the car door (8), pinion (5) meshed with the rack, The door can be opened and closed while idling the reducer 2 and the motor 1.

In addition, because the skew split type DC motor is adopted, caulking is minimized.

At this time, by appropriately setting the rotational speed of the motor (1) and the reduction ratio of the reducer (2) to minimize the mechanical load during manual idling, the passenger car door (8) can be sufficiently opened and closed can be opened.

The present invention as described above, the door is opened only while pressing the remote switch (1), the opening angle can be adjusted freely, and can be opened and closed manually as needed, locking the automatic opening and closing operation It is smoothly operated by the control box 13 and the shock absorber 7 provided with the release means, the delay means, etc., thereby realizing the high quality of the product, and absorbing the shock generated during the opening and closing of the passenger car door. It is possible to prevent damages and to prevent the user's safety accident by acting as a stopper for regulating the maximum opening angle. It can be easily installed by removing the stopper, and the device of the present invention can be easily installed at the location. It is characteristic.
