Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples：
Embodiment one：
In embodiment one shown in Fig. 1, which includes unmanned plane main body 1, the unmanned plane
1 lower section of main body hangs a phtographic lens 3 by spring 2；Adjusting is additionally provided between the phtographic lens 3 and unmanned plane main body 1
Mechanism, the adjusting mechanism can make to keep being relatively fixed between the phtographic lens 3 and unmanned plane main body 1 or be not fixed relatively.
In the present embodiment one, the adjusting mechanism includes a screw rod 4 extended downwardly from the unmanned plane main body 1,
The screw rod 4 is driven by the driving mechanism inside unmanned plane main body 1, makes it that can only lift vertically；The screw rod 4 drops to top
The top of phtographic lens 3 is stated in residence, and between 3 top of screw rod and phtographic lens during formation pressure, the phtographic lens 3 and nothing
Man-machine main body 1 is relatively fixed；When the screw rod 4 rises to disengaging 3 top of phtographic lens, phtographic lens 3 and unmanned owner
Body 1 is opposite to be not fixed.Specifically, the driving mechanism of the screw rod 4 include be sheathed on it is outside screw rod 4, can only be around screw axis
The stepper motor 42 that the thread bush 41 and the driving thread bush 41 of rotation rotate is formed.
According to embodiment one, the continuous rotation of thread bush 41 is made by stepper motor 42, screw rod 4 can be made continuous and slowly
Rise, so that the pressure between the phtographic lens 3 and screw rod 4 is continuous and slowly changes, until phtographic lens 3 and screw rod
4 depart from, so as to which phtographic lens 3 be avoided to be vibrated since pressure discharges suddenly.
Embodiment two：
In embodiment two shown in Fig. 2, what is different from the first embodiment is that there is no the drive of screw rod and screw rod in embodiment two
Motivation structure.The adjusting mechanism includes one section of iron staff upwardly extended from the axis of 3 top of phtographic lens along the spring 2
51 and one section of electromagnetic wand 52 extended downwardly from the unmanned plane main body 1 along the axis of the spring 2；The electromagnetic wand 52
Under power failure state, the phtographic lens 3, iron staff 51 naturally droop, and have interval between electromagnetic wand 52 and iron staff 51；The electricity
Under 52 "on" position of bar magnet, the electromagnetic wand 52 by the iron staff 51 upwards be attracted, make the unmanned plane main body 1, electromagnetic wand 52,
Iron staff 51, phtographic lens 3 are opposing stationary.
Compared to embodiment one, the adjusting mechanism of the present embodiment two is relatively simple, and is hardly damaged.
Embodiment three：
In embodiment three shown in Fig. 3, what is different from the first embodiment is that there is no the drive of screw rod and screw rod in embodiment three
Motivation structure.The adjusting mechanism includes one section of permanent magnetism upwardly extended from the axis of 3 top of phtographic lens along the spring 2
Stick 61 and one section of electromagnetic wand 62 extended downwardly from the unmanned plane main body 1 along the axis of the spring 2；The electromagnetic wand
62 under power failure state（Electromagnetic wand 62 is equivalent to an iron core at this time）, the Permanentmagnet bar 61 is attracted the electromagnetic wand 62 upwards,
Make the unmanned plane main body 1, electromagnetic wand 62, Permanentmagnet bar 61, phtographic lens 3 opposing stationary；The electromagnetic wand 62 is in "on" position
Under, electromagnetic wand 62 and 61 homopolar-repulsion of Permanentmagnet bar, as shown in figure 3, making that there is interval between electromagnetic wand 62 and Permanentmagnet bar 61.
For embodiment three, it is mainly in view of the unmanned plane camera chain and is in most cases used to absorb dynamic vision
Frequently, still life is only shot in a few cases；Therefore, only in a few cases, it is powered to electromagnetic wand 62, and in majority of case
Under, 62 no power of electromagnetic wand；It is sayed compared with embodiment two, embodiment three can save more electric energy.
Example IV：
For example IV shown in Fig. 4, what is different from the first embodiment is that the adjusting mechanism passes through the bullet for one section
The memory metal 7 of spring 2；For the memory metal 7 in its natural state in rigidity, the unmanned plane main body 1, lower end are fixed in upper end
Prop up the top of the phtographic lens 3；In the conductive state, lower end upsweeps the memory metal 7, departs from the photographic mirror
First 3, so that the phtographic lens 3 is naturally drooped in the lower end of the spring 2.
For example IV compared with other embodiments, the structure of the adjusting mechanism is the simplest.
Unmanned plane camera chain in the various embodiments described above passes through the adjusting machine in normal photographing video pictures
Structure makes the phtographic lens 3 keep opposing stationary with unmanned plane main body 1；And when still life is shot under unmanned plane floating state, lead to
The adjusting mechanism is crossed, the phtographic lens 3 is made to naturally droop in the lower end of the spring 2；In the case, unmanned plane main body
1 in the state of small size continuous shaking, this kind is vibrated by described 2 snubbers of spring, and the vibration of phtographic lens 3 is made significantly to cut
It is weak, so as to improve the clarity of still life shooting.
The spring 2 can be estimated as follows for the snubber ability of vibration：Under normal circumstances, unmanned plane
Oscillation Amplitude under floating state is less than 5mm, and vibration frequency is set to 10Hz；If the force variation value of the 2 deformation 5mm of spring
For F, if taking the weight of the phtographic lens as 100F, generated acceleration a is vibrated by unmanned plane main body 1 and is less than F/
(100F/g)=0.1m/s2, wherein, g is acceleration of gravity；And the action time of acceleration a be half of vibration period t, i.e. t=
1/20s, the vibration displacement L=at generated2/ 2=0.000125m, i.e. 0.125mm；It can be seen that as the 2 deformation 5mm of spring
Force variation value be less than 3 weight of phtographic lens 1/100 when, unmanned plane main body 1 is with the amplitude of 5mm（Actual capabilities are more
It is small）, the vibration frequency of 10Hz（Actual capabilities bigger, vibration frequency is bigger, then t is smaller, and L is smaller）When, the phtographic lens 3 is only
With the amplitude vibration of 0.125mm, the vibration of phtographic lens 3 is significantly inhibited, so as to improve the clarity of still life photography.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification for being made, equivalent substitution should all be included in the protection scope of the present invention.
