Description

[0001] Optical device assembly [0002]

The present invention relates to an optical device assembly, and more particularly, to an optical device assembly capable of adjusting the optical axis of the optical device through a simple configuration.

In general, optical devices are used in various fields. In particular, optical devices can be used to monitor external conditions. Such optical devices include various types of cameras, but they have been used in PTZ (Pan Tilt Zoom) systems in recent years. At this time, an optical device is installed in the PTZ system to acquire an image of the external environment. Such an optical device has an optical axis set to acquire a sharp external image. Such an optical axis has a great influence on the performance of the optical device. For example, if the optical axes of the optical device are different from each other after the set optical axis and the optical device are installed, the image can not be properly acquired or a clear image can not be obtained. Accordingly, various methods are attempted to match the different optical axes as described above.

Specifically, various methods can be used to match different optical axes. For example, the position of the optical device can be adjusted through the stage to align different optical axes. In addition, the position of the optical device can be adjusted through two or more adjustment lever driving parts to align different optical axes.

Particularly, in the above case, a technique of manually operating the spindle to align the optical axis or adjusting the position of the optical device through two or more adjustment lever driving units is disclosed in Korean Patent Laid-Open Publication No. 2011-0137267 Device and optical axis alignment method, Applicant: Huh, Sung Yong).

In addition, the fourth gear 160 may be disposed at a predetermined distance from one side of the support base 120.

The third gear 153 and the fourth gear 160 may be formed in various shapes. For example, the third gear 153 and the fourth gear 160 may be formed of a worm gear set. Specifically, the third gear 153 may be formed as a worm gear, and the fourth gear 160 may be formed as a worm wheel gear.

The third gear 153 and the fourth gear 160 may be formed of a bevel gear set. Specifically, the third gear 153 and the fourth gear 160 may be helical bevel gears, straight bevel gears, or spiral bevel gears in which the rotational axes intersect vertically.

The optical device assembly 100 may include a first gear 140 and a drive gear 170 selectively meshing with one end of the second gear portion 150. At this time, the driving gear 170 may rotate the first gear 140 or the second gear 151 by contacting the first gear 140 or the second gear 151 according to the selection. In addition, the drive gear 170 may be disposed between the support base 120 and the housing 130.

The optical device assembly 100 may include an adjustment lever 180 that performs selective engagement of the drive gear 170. At this time, the control lever 180 may be installed so as to be linearly movable, and may be disposed such that one end thereof is spaced apart from the support base 120 by a predetermined distance. In particular, the adjustment lever 180 may be rotatably mounted on the housing 130. At this time, the control lever 180 may be coupled to the housing 130 through a bearing or a bush.

The control lever 180 includes a housing 120 formed to surround an outer periphery of the optical device 110, the support 120, the first gear 140, the second gear 150, and the driving gear 170, As shown in Fig. At this time, one end of the control lever 180 may be inserted into the support 120. Therefore, the control lever 180 moves and not only meshes with the first gear 140 or the second gear 151, but also rotates the first gear 140 or the second gear 151 by rotating.

Meanwhile, the optical device assembly 100 may include an adjusting lever driver 190 for rotating or linearly moving the adjusting lever 180. At this time, the control lever driving unit 190 may change the position of the control lever 180 based on an external signal, so that the driving gear 170 can be engaged with the first gear 140 or the second gear 151. The control lever driving unit 190 may rotate the control lever 180 to rotate the driving gear 170 engaged with the first gear 140 or the second gear 151.

The adjusting lever driving unit 190 may include a linear driving unit 192 connected to the adjusting lever 180 to move the adjusting lever 180. The linear driving unit 192 may include a cylinder that is directly connected to the rotation driving unit 191 or the control lever 180 to vary the position of the control lever 180.

The linear driving unit 192 may include a motor and gears connected to the adjusting lever 180 to linearly move the adjusting lever 180. In this case, the linear driving unit 192 is not limited to the above, and may include any device capable of linearly moving the adjusting lever 180.

The linear driving unit 192 may include a sliding member 192b that is partially inserted into the sliding groove 192a-1 and linearly moves the guide member 192a and is connected to the adjusting lever 180. [

The sliding member 192b includes a sliding portion 192b-1 inserted into the sliding groove 192a-1 and a connecting portion 192b-1 extending from the sliding portion 192b-1 and connected to the adjusting lever 180 192b-2.

At this time, the control lever 180 may include a connection part fixing frame 181 on which the connection part 192b-2 is installed. The connecting portion fixing frame 181 may be formed larger in area than other portions of the adjusting lever 180. Specifically, the connection part fixing frame 181 may protrude from the outer surface of the control lever 180 so as to partially surround the connection part 192b-2.

Further, a plurality of connection stationary frames 181 may be provided. At this time, the plurality of connection part fixing frames 181 may be arranged to be opposed to each other at a predetermined interval. Accordingly, the plurality of connection part fixing frames 181 prevent the connection part 192b-2 from being displaced from the adjustment lever 180 or varying the position on the upper surface of the adjustment lever 180 when the connection part 192b-2 moves can do.

On the other hand, the driving device 192c may include various devices. For example, the drive device 192c may include a hydraulic cylinder, a pneumatic cylinder, a motor, a device driven by magnetic force or electric force, and the like.

The optical device assembly 100 may include a control unit (not shown) that controls the movement of the control lever 180 based on the optical axis of the predetermined optical device 110. At this time, the control unit may actuate the control lever driving unit 190 to vary or rotate the position of the control lever 180.

The control unit may control the adjusting lever driving unit 190 to vary the position of the adjusting lever 180 so that the driving gear 170 and the first gear 140 are engaged with each other to tilt the optical device 110. The control unit may control the adjusting lever driving unit 190 to vary the position of the adjusting lever 180 so that the driving gear 170 and the second gear 151 are engaged with each other to rotate the fan.

The optical device assembly 100 may include a position sensing sensor unit 195 for sensing the position of the adjustment lever 180. [ At this time, the position detecting sensor unit 195 may be formed in various shapes. For example, the position detection sensor unit 195 may be formed in a switch shape and may be configured to detect the position of the control lever 180 in real time.

Hereinafter, the position detecting sensor unit 195 will be described in the form of a switch that operates only when the driving gear 170 is incorporated into the first gear 140 or the second gear 151 for convenience of explanation.

Hereinafter, the operation of the optical device assembly 100 will be described in detail.

3 is a perspective view showing a first operation of the optical device assembly 100 shown in FIG. 4 is a perspective view showing the rear side of the optical device assembly 100 shown in FIG.

Referring to FIGS. 3 and 4, the optical device assembly 100 may be previously set in an optical axis and stored in the control unit. At this time, the optical axis may be set at the time of designing or manufacturing the optical device 110.

The supporting base 120 on which the optical device 110 is installed may be installed in the housing 130 and the housing 130 may be installed on the frame 199 so as to be rotatable. At this time, the third gear 153 may be installed to engage with the fourth gear 160. In particular, the third gear 153 and the fourth gear 160 may be engaged with each other as described above.

When the installation is completed as described above, the optical device 110 can be operated. At this time, the controller can determine whether the optical axis of the optical device 110 coincides with a preset optical axis. The control unit may control the adjustment lever driving unit 190 to tilt or rotate the optical device 110 when it is determined that the optical axis of the optical device 110 is different from the predetermined optical axis. Hereinafter, the case of rotating the fan will be described in detail.

When the controller determines that the optical axis of the optical device 110 is deviated from the predetermined optical axis, the control unit controls the adjustment lever driver 190 such that the adjustment lever 180 is engaged with the first gear 140 .

Specifically, the control unit can receive the position of the control lever 180 from the position detection sensor unit 195. At this time, if it is determined that the position of the control lever 180 detected by the position detection sensor unit 195 is out of a preset position, the control unit may drive the driving unit 192c.

The driving device 192c can be driven to linearly move the sliding member 192b. Specifically, when the driving device 192c operates, a force is applied to the sliding portion 192b-1, and the sliding portion 192b-1 can slide along the sliding groove 192a-1. At this time, the sliding portion 192b-1 may move the connecting portion 192b-2 and the connecting portion 192b-2 may move the adjusting lever 180 in the moving direction of the sliding portion 192b-1.

When the first gear 140 and the driving gear 170 are engaged while the control lever 180 continues to move as described above, the position sensor unit 195 can detect the position of the control lever 180.

The position detection sensor unit 195 can transmit a signal to the outside when the control lever 180 is positioned as described above. At this time, the signal is transmitted to the controller, and the controller can determine that the first gear 140 and the driving gear 170 are engaged.

If it is determined as described above, the controller may control the adjustment lever driver 190 to rotate the adjustment lever 180. Specifically, the control unit may control the rotation driving unit 191 to rotate the control lever 180.

At this time, when the rotation driving unit 191 is operated, the control lever 180 rotates. The control lever 180 rotates while rotating the driving gear 170 and the driving gear 170 is engaged with the first gear 140 to rotate the first gear 140.

In particular, when the first gear 140 rotates as described above, the optical device 110 can rotate with the first gear 140. Accordingly, the optical device 110 rotates in the vertical direction by the rotation of the first gear 140.

5 is a perspective view showing a second operation of the optical device assembly 100 shown in FIG. 6 is a perspective view showing the rear side of the optical device assembly 100 shown in Fig.

Referring to FIGS. 5 and 6, when the tilt rotation is performed, the controller can determine that the predetermined optical axis is on the left or right side of the optical axis of the optical device 110. FIG. At this time, the control unit may operate the control lever driving unit 190 to separate the driving gear 170 and the first gear 140 from each other.

Specifically, the control unit may stop the rotation driving unit 191 and control the linear driving unit 192 to operate. At this time, the controller activates the driving device 192c, and the sliding part 192b-1 can move along the sliding groove 192a-1 according to the operation of the driving device 192c. The sliding portion 192b-1 moves while the connecting portion 192b-2 moves while the connecting portion 192b-2 moves the adjusting lever 180. [

In addition, when the control lever 180 is moved, the driving gear 170 connected to the control lever 180 can be separated from the first gear 140. In this case, when the driving gear 170 is disengaged from the first gear 140 as described above, the position detection sensor unit 195 may transmit the position of the control lever 180 to the control unit. The control unit may change the position of the control lever 180 so that the driving gear 170 is engaged with the second gear 151 by continuously operating the driving device 192c. At this time, the method of moving the control lever 180 is the same as that described above, and thus a detailed description thereof will be omitted.

Meanwhile, when the driving gear 170 is integrated with the second gear 151, the position sensing unit 195 may sense the signal and transmit the signal to the control unit. The controller may control the rotation driving unit 191 to rotate the control lever 180 without changing the position of the control lever 180. [

When the rotation driving unit 191 is operated, the driving gear 170 rotates to rotate the second gear 151. The second gear 151 can rotate the shaft 152 and the third gear 153 provided on the shaft 152. At this time, the third gear 153 can rotate along the gear of the fourth gear 160.

Specifically, when the third gear 153 rotates, the fourth gear 160 may be fixed to the frame 199 as described above. At this time, the shaft of the fourth gear 160 connecting the fourth gear 160 and the frame 199 may be inserted into the housing 130 so as to be rotatable.

The third gear 153 and the fourth gear 160 are engaged with each other in the form of a worm gear so that the third gear 153 can be rotated along the outer circumferential surface of the fixed fourth gear 160. At this time, when the third gear 153 rotates as described above, the optical device 110, the support base 120, and the housing 130 can rotate together with the rotation of the third gear 153.

Specifically, since the fourth gear 160 is fixed to the frame 199, it may not rotate according to the driving of the third gear 153. The third gear 153 can rotate along the outer peripheral surface of the fourth gear 160 as described above.

At this time, the support base 120, to which the third gear 153 is rotatably installed, can rotate together with the third gear 153. Further, when the support table 153 rotates, the housing 130 can rotate together with the support table 153.

When the housing 130 rotates as described above, a bearing is disposed between the shaft of the fourth gear 160 and the housing 130 so that the fourth gear 160 and the housing 130 can move relative to each other. Further, since the housing 130 is rotatably installed on the frame 199, the housing 130 can rotate on the frame 199 in accordance with the rotation of the support 120.

Therefore, the optical device assembly 100 can solve the tilt rotation or the fan rotation of the optical device 110 through the single adjustment lever driver 190, thereby simplifying the configuration. In addition, since the optical device assembly 100 can be manufactured by minimizing the apparatus, the assembly cost can be reduced and the maintenance property can be increased.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications and variations without departing from the spirit and scope of the invention. Accordingly, it is intended that the appended claims cover all such modifications and variations as fall within the true spirit of the invention.
