Embodiment
For further setting forth the utility model for the technological means reaching predetermined object and take and effect, below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in detail as rear.
The lens protection mechanism for optical camera that the utility model provides, no matter open or close, occupies little space, lens protection mechanism of the present utility model and various piece thereof will be described in detail belows.
As depicted in figs. 1 and 2, camera lens 2 protection mechanism for optical camera of the application, being comprised: roller shutter 3, is arranged on the spool fixed border of camera lens 2 by spool 13, and be wound on spool 13.Pulling device, comprise pulling rope 12, rolling wheel 11 and tractive motor 9, rolling wheel 11 and tractive motor 9 are arranged on the rolling wheel fixed border of the camera lens 2 relative with spool fixed border, one end of pulling rope 12 connects rolling wheel 11 and is wound on rolling wheel 11, the other end of pulling rope 12 connects the winding end of roller shutter 3, tractive motor 9 is coaxially connected to rolling wheel 11, rotates to drive rolling wheel 11.Spool fixed border described in literary composition and rolling wheel fixed border are two frames of the camera lens be oppositely arranged, and can be two frames up and down of camera lens, can be also the right and left frame, and the definition provided is the installation site in order to better limit spool and rolling wheel.
The lid of camera lens 2 is designed to the mode of roller shutter 3, under the state that roller shutter closes camera lens, roller shutter is approximately one block of plate, well can play the effect of protection optical lens.Under the state that roller shutter is opened, roller shutter 3 can be rolled, and is wound on spool, to be retracted in minimum space.Lens protection mechanism can be conformal with the covering 1 of aircraft, becomes a part for aircraft skin 1, makes aircraft have good aeroperformance and Stealth Fighter.
As preferably, as depicted in figs. 1 and 2, lens protection mechanism, also comprises winding motor 10, and winding motor 10 is coaxially connected to spool 13, and winding motor 10 and tractive motor 9 coordinate the opening and closing realizing roller shutter 3.
Further, as shown in Figures 2 and 3, roller shutter 3 comprises many Metallic rod and many metal line 19, and many Metallic rod are arranged side by side along the axis direction of spool 13, and many wires 19 alternate in many Metallic rod along the direction of pulling rope 12.While being convenient to roller shutter coiling axle 13 winding thus, improve the structural strength of roller shutter.
In addition; as shown in Figures 2 and 3; lens protection mechanism; also comprise elastic device 5; elastic device 5 comprises pull bar 16, spring, litter 17 and nut 18, is connected to the winding end of roller shutter 3, and pulling rope 12 drives roller shutter 3 to rotate by tractive pull bar 16; pull bar 16 is provided with threaded hole, and can slide in this threaded hole.Litter 17 is hollow stem and an end of litter 17 is provided with boss, litter 17 is contained in threaded hole, metal wire 19 towards the stiff end of rolling wheel fixed border through after litter 17, nut 18 is tightened on threaded hole, the stiff end of metal wire 19 is pressed on boss on the side of volume 1 fixed border, spring wrap on litter 17, and is arranged on the side of boss near roller shutter 3.Can find out in figure, the stiff end of metal wire 19 is crushed on boss near between the side of rolling wheel fixed border and nut 18, and spring is arranged on boss near between the side of roller shutter 3 and pull bar 16.Thus in the folding and unfolding process of roller shutter 3, spring has certain pretightning force, when the pulling force of pulling rope increases, the pressure increase that spring bears, according to Hooke's law, spring is shortened by compression, play the effect of flexible buffer, therefore roller shutter 3 is in tension all the time, avoids the friction between roller shutter 3 and track 4 or collision, is convenient to the smooth opening of roller shutter 3 and closes.
Pulling rope can be wire rope, and when roller shutter 3 is opened, because wire rope is very thin, it is very little to blocking of optics, can ignore the impact that it causes.
As depicted in figs. 1 and 2, the two ends of pull bar 16 are provided with slide block 7, camera lens 2 is respectively arranged with slide rail 8 and track 4 along on the frame in pulling rope direction, relative to camera lens 2, slide rail 8 is arranged at the outside (see Fig. 1) of track 4, wherein slide rail 8 coordinates with slide block 7 and realizes pull bar 16 along the slip on the direction of pulling rope 12, slide block 7 and slide rail 8 also can coordinate for accurate rolling, and avoid pulling rope to exert oneself in traction process thus roller shutter 3 that inequality causes is the fault such as stuck or friction force increase in track 4.Track 4 is configured to the U-type groove towards roller shutter 3, and the side in the direction along pulling rope 12 of roller shutter 3 is held in U-type groove, and under the drive of pull bar 16, roller shutter 3 slides in U-type groove.It should be noted that, the effect of this track 4 supports roller shutter 3 to slide therebetween, effectively prevent roller shutter 3 from issuing at External Force Acting (as the impact such as gravity or air-flow) and give birth to pendant or bending, and straight line or curve can be designed to as required, realize the conformal design of roller shutter 3 and aircraft skin 1 or contour of the vehicle thus, improve the stealthy function of camera lens.It should be noted that, tractive motor, winding motor and track 4 etc. can be fixed on the frame of camera lens 2.
In addition as depicted in figs. 1 and 2; lens protection mechanism; also comprise controller (not shown) and touching switch 14; on the touching switch 14 spool fixed border that is arranged at camera lens 2 respectively and rolling wheel fixed border; controller divides level signal to be connected to touching switch 14, tractive motor 9 and winding motor 10; when pull bar 16 touches touching switch 14, after touching switch 14 sends touching signal to controller, controller controls tractive motor 9 and winding motor 10 stops operating.The reliable open and close of roller shutter can be guaranteed thus.
Therefore, the open and close process of roller shutter 3 can be:
When roller shutter 3 needs to open, the reverse rotation of tractive motor, releases around the wire rope on rolling wheel 11, meanwhile, winding motor rotates forward, by roller shutter 3 around on spool 13, when roller shutter 3 is opened completely, pull bar 16 can bump against trigger switch 14, two motor stop motions simultaneously.Same reason, when roller shutter 3 needs closed, performs the inverse process of said process.
Receive to realize two motors one synchronous operation that one puts speed, roller shutter 3 is provided with pulling force sensor 15, the motion process of whole roller shutter 3 realizes closed-loop control by controller control pulling force sensor 15, touching switch and a motor have been come.Pulling force sensor 15 is arranged at the junction of pulling rope 12 and pull bar 16, after gathered pulling force signal is sent to controller by pulling force sensor 15, control the rotating speed controlling tractive motor 9 and winding motor 10 according to pulling force signal, consistent with the folding and unfolding speed of the folding and unfolding speed with tractive motor 9 that make winding motor 10.
By the explanation of embodiment, should to the utility model for the technological means reaching predetermined object and take and effect be able to more deeply and concrete understanding, but appended diagram is only to provide with reference to the use with explanation, is not used for being limited the utility model.
