Hereinafter, the technical configuration of the present invention will be described in more detail with reference to the accompanying drawings.

Figure 3a is a schematic view showing a door fixing device for a vehicle according to the present invention, Figure 3b is a side view of a vehicle incorporating the door fixing device of the present invention, Figure 4a is a schematic view showing the overall configuration of the present invention, Figure 4b Is a cross-sectional view showing the engagement portion between the rack gear and the pinion gear.

3A and 3B, the present invention will be described with reference to the present invention. In the automobile door 1, a predetermined space formed by the door inner panel 1a and the door outer panel 1b is formed, and the cylinder 30 having a predetermined length is formed in the space. Is provided perpendicular to the door (1).

The cylinder 30 is a hollow hollow body, and is installed to be fixed to the door inner panel 1a through a bracket 31 surrounding the outer circumferential surface thereof.

Meanwhile, as shown in FIGS. 4A and 4B, the cylindrical body 30 is provided with a fixing bar 32 which is movable up and down in the interior thereof, and the fixing bar 32 has a rack having a predetermined length in one longitudinal direction thereof. Gear 32a is formed.

In addition, the fixing bar 32 should have a length sufficient to allow the lower end 32b of the fixing bar 32 to penetrate the lower end portion 1c of the door to the ground.

In addition, the fixing bar 32 is engaged with the rack gear 32a formed in the fixing bar 32 so that the fixing bar 32 can be moved downward to protrude to the ground through the through hole (1d) of the door lower portion (1c) A pinion gear 33a is provided, and the pinion gear 33a is integrally connected through a shaft 33b and a motor 33 that provides power so that the pinion 33a can be rotated.

That is, the rack gear 32a meshed with the pinion gear 33a receives power by the rotation of the motor 33, and thus the fixed bar 32 on which the rack gear 32a is processed is the tubular body 30. When the fixing bar 32 is moved downward, the lower end 32b of the fixing bar 32 passes through the through hole 1d formed in the door lower portion 1c and protrudes to the ground. It will be.

Here, the rack gear 32a formed on the fixed bar 32 should be processed only by the distance from the lower end portion 1c to the ground so that the pinion gear 33a is fixed to the rack of the fixed bar 32 even if the motor 33 is continuously rotated. It is no longer possible to transmit power to the gear 32a to prevent the fixing bar 32 from protruding excessively. If the length of the rack gear 32a is not considered, the fixing bar 32 continuously protrudes due to the continuous rotation of the motor 33 even though the end 32b of the fixing bar 32 touches the ground. In the end, the phenomenon in which the door 1 is lifted will occur and the door 1 will be twisted.

And, the lower end 32b of the fixing bar 32 is attached to the louver 32c having an elastic force so that the door 1 can be more easily fixed when the fixing bar 32 is in contact with the ground. In addition, after the fixing bar 32 is completely inserted into the door 1, the louver 32c at the end of the fixing bar has a function of sealing by blocking the through hole 1d of the door 1. .

On the other hand, the motor 33 is a bidirectional motor capable of forward and reverse rotation, the motor 33 must be operated only when the door (1) is open. Therefore, a means for detecting the open state of the door 1 is required, and the door switch 35 is substituted for this means.

The door switch 35 is typically installed at one side of the door 1 in contact with the vehicle body, and is used in a place such as a buzzer or a warning light indicating the door open state.

Therefore, the power applied from the battery 36 which is the main power source of the vehicle passes through the door switch 35, and the door switch 35 allows the power to be supplied to the motor 33 side only when the door 1 is open. That is, the power is supplied or cut off to the motor 33 by the door switch 35.

In addition, an operating part 34 is provided between the door switch 35 and the motor 33 so that power applied from the door switch 35 enters the operating part 34 for operating the motor 33. The operating unit 34 not only operates the motor 33 but also controls the direction of rotation of the motor 33. The operating unit 34 may be installed at any position in the cabin, Preferably the actuator 34 is positioned around the power window switch.

That is, when the operation part 34 is set to the down position in the state in which the door 1 is opened, the fixing bar 32 protrudes from the lower end part 1c of the door to the ground to fix the door 1 not to close. On the contrary, when the operating part 34 is set to the up position, the fixing bar 32 is inserted into the door 1 again, and at the end, the louver attached to the end 32b of the fixing bar 32 32c blocks and seals the through-hole 1d of the door lower part 1c.

The operation of the present invention in the above configuration is as follows.

When unloading or loading cargo in the cabin with the door (1) open and difficult to lock, such as on a windy plain or especially on a slope with a high slope, the door (1) must first be angled. If the opening portion 34 is set to the down position as the motor 33 rotates forward, the pinion gear 33a connected to the motor 33 transmits the force to the rack gear 32a, so that the fixing bar 32 moves downward. Will move.

The fixing bar 32 protrudes only until it comes in contact with the ground, but the rack gear 32a is no longer engaged with the pinion gear 33a even though the operating part 34 is kept in the down position in this state. 32 is no longer moved downwards.

In addition, when releasing the fixing bar 32 which has fixed the door 1 to the ground, when the operating part 34 is set to the up position, the motor 33 rotates in reverse, thereby fixing the fixing bar 32. ) Will move upwards.

After the fixing bar 32 is completely inserted into the door 1, the sealing louver 32c attached to the end 32b of the fixing bar 32 blocks the through hole 1d of the door. Have. The louver 32c has a function of more firmly fixing the door 1 when the fixing bar 32 is in contact with the ground, and penetrating the door when the fixing bar 32 is embedded in the door 1. It has a function to seal the ball 1d.

On the other hand, in the state in which the door 1 is closed, the motor 33 does not operate even when the operating part 34 is operated. This is a safety device for preventing the overload of the motor 33. This is because the sensing door switch 35 is off and power is not applied to the operation part 34.

As described above, according to the fixing device for a door for a vehicle according to the present invention, the door can be fixed to a desired position by a simple operation of an operation unit provided at one side of the door when the door is opened. As it is fixed, it is not only very convenient when loading cargo, but also has a unique effect of preventing a safety accident that may be caused by a door.
