The job stability for protecting movable component avoids generating angular force during use because asymmetric, camera lens mounting base 4 it is upper
Lower direction of motion force unbalance generates stress, destroys flexible take the photograph to the functional stabilization of head and to the flexible damage taken the photograph to head
Wound.
First spring leaf 6 is provided with 2.
First spring leaf 6, which is provided with gasket, the first pad hole, is provided with first boss gasket between 2 first spring leafs 6,
For the big one end of first boss gasket between 2 flat spring pieces, small one end passes through the first pad hole.Camera being collided or
Head is dropped, camera lens mounting base 4 is bigger to the impact force of pedestal 8, directly impacts to pedestal 8, therefore bottom is arranged 2 first
Spring leaf 6, and gasket is arranged among the first spring leaf 6 greatly buffers camera lens 1 and installs impact to pedestal 8, or even prevents pair
The impact of pedestal 8.First spring leaf 6 will by impact camera lens 1 installation rebound, second spring piece 5 to camera lens mounting base 4 again
Buffering and rebound is carried out, it, will be to camera lens mounting base 4 after being buffered several times back and forth before the first spring leaf 6 and second spring piece 5
Impact force is gentle, protects camera lens 1 and camera lens mounting base 4.In the case where normal work, camera lens 1 and camera lens mounting base 4 are to
One spring leaf 6 and second spring piece 5 do not contact, but are more than maximum electromagnetic force suffered by loop 11, and camera lens mounting base 4 can be touched
To the first spring leaf 6 or second spring piece 5, the first spring leaf 6 or second spring piece 5 play camera lens 1 and camera lens mounting base 4
Protective effect.
Pedestal 8, camera lens mounting base 4, upper bracket 3 and upper shell 2 all pass through integrally casting；Double damping protection lens driving dresses
It sets and is fixed between non-movable member by dispensing.Non-movable member after mounting, such as needs complete fitting, to the mould of integrally casting
Tool requires too high, less meets economic requirement, can ensure that be mechanically fixed stability and complete appearance it is beautiful in the case where, reduce
Pedestal 8, camera lens mounting base 4, upper bracket 3 and upper shell 2 polymorphic structure, greatly reduce difficulty of processing, resulting point seam
It is fixed, inactive each component can be fixed by dispensing, a seam is filled up to complete and economical and practical and facilitates operation.
When pedestal 8 is impacted, the first damper assembly 12 stress first, the first damper assembly 12 bears biggish punching
It hitting power and then passes through camera lens mounting base 4 and be transferred to the second damper assembly 13, the second damper assembly 13 absorbs impact power, if first
The impact force that damper assembly 12 and the second damper assembly 13 are born exceeds its rated value, the first spring leaf 6 and second spring piece 5
It shields.
Under the action of double damper assemblies and the first spring leaf 6, second spring piece 5, buffers and rushed suffered by camera lens 1 significantly
Power is hit, great protection is played to camera lens 1 and camera lens mounting base 4, other opposite cameras considerably increase impact resistance, can
Suitable for special environment.
First damper assembly 12 and the second damper assembly 13 are gas spring damper, 12 damping force of the first damper assembly it
It is greater than the sum of camera lens 1 and the gravity of camera lens mounting base 4 with the starting damping force of the sum of 13 damping force of the second damper assembly.Gas
Spring is in the case where stress very little, resistance very little, and as stress is bigger, generated damping force is also bigger, can be great
Suffered impact force is mitigated, camera lens 1 is reduced and the hard of camera lens mounting base 4 is puted forth effort.
Camera lens mounting base 4 is provided with camera lens mounting hole, is provided with screw thread in camera lens mounting hole, and camera lens 1, which passes through, to match
It is threadably mounted in camera lens mounting base 4 and through camera lens mounting base 4.
The second spring piece 5 is provided with 2, and the second spring piece 5, which is provided with gasket, the second pad hole, and described 2
Second boss gasket is provided between piece second spring piece 5, the big one end of the second boss gasket is small between 2 flat spring pieces
One end pass through the second pad hole.Second spring piece 5 is arranged to 2, the safeguard function of camera is further promoted, greatly
The impact force for having buffered camera lens 1 and camera lens mounting base 4, camera lens 1 and camera lens mounting base 4 are greater than in the impact force by external force
Loop 11 is when being powered when produced maximum electromagnetic force, and camera lens mounting base 4 is by the first spring leaf 6 or second spring piece 5
Limitation, the first spring leaf 6 or second spring piece 5 generate elastic force, buffer to camera lens mounting base 4, such as by biggish impact force
When, second first spring leaf 6 or the further cushion impact forces of second spring piece 5 protect camera lens and camera lens to install well
Seat.
The technical solution of each embodiment can be combined in the utility model, and the technical characteristic in embodiment can also carry out group
Conjunction forms new technical solution.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with the power
Subject to the protection scope that benefit requires.
