The worm 420 has a helical gear tooth and is connected coaxially with the rotation shaft of the drive motor 410.

The worm gear 430 has a gear tooth engaged with the helical gear tooth of the worm 420 and is installed in a vertical direction with the worm 420. The worm gear 430 is decelerated and rotated in conjunction with the worm 420.

The main gear 440 has a smaller number of gear teeth than the worm gear 430 and is connected coaxially with the worm gear 430 at the upper side of the worm gear 430.

The driven gear 450 has a larger number of gear teeth than the worm gear 430 and is installed to be engaged with the gear teeth on the main gear 440.

Rotation of the worm gear 430 is further decelerated by the engagement between the main gear 440 having a smaller number of gear teeth than the worm gear 430 and a driven gear 450 having fewer gears than the worm gear 430. Second deceleration) is transmitted to the driven gear 450.

The pinion gear 460 has a smaller number of gear teeth than the driven gear 450 and is connected coaxially with the driven gear 450 under the drive motor 410.

The rack gear 470 is provided with a plurality of gear teeth arranged in front and rear to be engaged with the gear teeth of the pinion gear 460, and in a straight line forward and backward in conjunction with the rotation of the pinion gear 460 under the drive motor 410. Is moved.

By engagement between the pinion gear 460 and the rack gear 470 having fewer gears than the driven gear 450, the rotation of the driven gear 450 is further decelerated (3rd deceleration) to allow the rack gear 470 to rotate. Is converted to linear motion.

By the multi-stage reduction structure as described above, the position of the guide block 200 may be precisely adjusted by the rotational driving of the driving motor 410.

In addition, as the rack gear 470 is positioned below the driving motor 410, even if the rack gear 470 protrudes out of the case 480, foreign matter, moisture, or the like is in contact with the case 480, It is precipitated at the bottom of the case 480 to prevent the transfer to the drive motor 410 side.

If a partition is installed between the rack gear 470 and the driving motor 410, the driving motor 410 may be more safely protected from foreign matter and moisture.

When the reverse sensing device 760 detects the reverse of the vehicle 10 (for example, driving a rear gear, etc.), the controller 800 drives the driving motor 410 in the forward direction to guide the guide block 200. ) Is advanced backward as shown in FIG. 8 (see FIG. 12).

If the backward sensing of the vehicle 10 is not detected by the backward sensing device 760, the controller 800 drives the driving motor 410 in the reverse direction to return the guide block 200 to the initial state as shown in FIG. 6. (Forward)

Referring to FIG. 1, the vehicle camera apparatus according to the exemplary embodiment of the present invention has a structure in which a camera operation button 710 is further installed in the vehicle 10 in which the driver's seat is located.

Even when the vehicle 10 is not reversing (for example, even when the vehicle 10 is stopped), when the camera operation button 710 is operated, the controller 800 receives an operation signal of the camera operation button 710. Drive the drive device 400

When the driver manipulates the camera operation button 710, the controller 800 drives the driving motor 410 to rotate in the forward direction, and the guide block 200 is moved to the rear as shown in FIG. 8 to move the camera 300. Is exposed outside the housing 100.

When the camera 300 needs to clean the lens of the camera 300 due to the sharpness of the captured image, when the driver operates the camera operation button 710, the camera 300 is exposed to the outside of the housing 100. ) Easy to clean and clean the lens.

In addition, even when inspection of the installation state of the camera 300 is necessary, the camera operation button 710 can be operated without having to detach the vehicle camera device from the tail gate 15 or unfold the cover 500 forcibly. As a result, the camera 300 can be easily inspected while being exposed to the outside of the housing 100.

If the sensing means for detecting the position of the guide block 200 and the driving state of the drive device 400 and transmits to the controller 800, according to the position of the guide block 200, the driving state of the drive device 400 Precise control is possible (see Fig. 12).

The displacement sensor 720 is installed inside the moving hole 110 of the housing 100 to detect the linear displacement of the guide block 200, and detects the position of the guide block 200 and transmits it to the controller 800.

The displacement sensor 720 may be a contact sensor such as electromagnetic induction, magnetic, or optical, or a non-contact sensor such as vortex, optical, or ultrasonic.

Referring to FIG. 8, the displacement sensor 720 according to the exemplary embodiment of the present invention has an inner surface of the moving hole 110 so that the direction of extension of the guide groove 111 formed in the inner surface of the moving hole 110 is a sensing path. It is installed on the part, and detects the position of the guide protrusion 221.

As the moving hole 110 is formed to be recessed along the moving path of the guide block 200, the guide block 221 may be detected by detecting the position of the guide protrusion 221 on the moving hole 110 by the displacement sensor 720. It is possible to accurately detect the position of the 200).

The rotation angle sensor 730 is installed on a connecting shaft 451 connecting the rotating shaft or driven gear 450 and the pinion gear 460 of the driving motor 410 having the rotational displacement, and the rotating shaft or the connecting shaft 451. Detect the rotational displacement of the transmission to the controller (800).

10 and 11, the rotation angle sensor 730 according to an embodiment of the present invention is installed on the connecting shaft 451 connecting the driven gear 450 and the pinion gear 460, the connecting shaft ( A rotational displacement of 451 is sensed.

When the position of the guide block 200 is detected by the displacement sensor 720, the controller 800 calculates the displacement of the remaining guide block 200 to the desired position (hereinafter referred to as the remaining distance) and the driving motor ( 410 is driven.

At this time, the rotation angle sensor 730 detects whether the connection shaft 451 is rotated by the desired rotation angle displacement corresponding to the remaining distance, and if the target rotation angle displacement is detected by the rotation angle sensor 730, the controller 800 ) Stops the driving of the driving motor 410.

For convenience of explanation, it is assumed that the distance between the displacement sensor 720 and the guide protrusion 221 is 0 in a state as shown in FIG. 6 and 10 in a state as shown in FIG. 8.

 When the guide block 200 is moved from an initial state as shown in FIG. 6 to a state as shown in FIG. 8, the position of the guide block 200 is detected as 0 in the displacement sensor 10, and the controller ( 800 drives the driving motor 410 in the forward direction.

At this time, the rotation angle displacement of the connecting shaft 451 is output (transmitted) to the controller 800 by the rotation angle sensor 730, and the connecting shaft 451 is rotated at a rotation angle displacement of 330 ° corresponding to the remaining distance 10. When rotated, the controller 800 stops driving the driving motor 410.

By using the displacement sensor 720 and the rotation angle sensor 730 as described above, while detecting the position of the guide block 200 and the driving state of the drive device 400 in real time, according to the position of the guide block 200 The driving state of the driving device 400 can be precisely controlled.

In the controller 800, the guide block 200 to the rear target position as shown in FIG. Calculate the remaining movement distance of the) and compare it with the rotation angle displacement of the rotation angle sensor 730.

Although it is detected that the rotation angle sensor 730 is rotated at a rotation angle displacement corresponding to the remaining distance, when the controller 800 detects that the reference value (for example, 1 kpa) has been reached by the pressure sensor 740, the controller 800 receives the received signal. The forward driving of the drive motor 410 is stopped.

By the method of controlling the position of the guide block 200 as described above, the position of the guide block 200 can be accurately moved to a desired point.
