2. in above scheme, passing through the setting of three bottom boss, on the one hand, only need to guarantee the surface of three bottom boss
The depth of parallelism and flatness, for the groove compared to previous entire lower surface, this case greatly reduce to the surface depth of parallelism and
The area of planarity requirements reduces the requirement to mold, reduces production cost；On the other hand, this by bottom boss
The design of protrusion, and the arrangement of " triangle " can also be convenient for Client Enterprise by voice coil motor and the other components of camera（Such as
Bracket）Connection positioning, and the stability after positioning can be promoted.
3. in above scheme, the upper surface of the flat lid is additionally provided with anti-rotation convex block, which corresponds to voice coil
Anti-rotation block setting on motor carrier, the two cooperate for positioning the carrier.
4. in above scheme, the upper surface of the flat lid is additionally provided with precompressed convex block, the precompressed convex block and voice coil horse
It is equipped with up to the precompressed convex block on carrier, the two collective effect makes it generate a predeformation in the lower elastic slice.By becoming in advance
When shape will be helpful to coil and be powered suddenly, carrier can have a small displacement, will not cause to damage to carrier.
5. in above scheme, the lower surface of the flat lid is additionally provided with multiple PIN foot, it to be used for electric property coupling camera
Other components.
6. in above scheme, the lower surface of the flat lid is equipped with a bottom recesses around the through-hole, each described
Bottom boss is set in the bottom recesses.
The working principle and advantage of the utility model are as follows：
A kind of newly-designed voice coil motor upper cover component of the utility model, lid middle part offer through-hole, contraposition camera shooting
Head mirror piece；Lid upper surface is set there are four positioning column, multiple hot molten columns and a dust ring；Each positioning column is located at upper surface
Four angles position yoke；Each upward projection of hot molten column, welding position lower elastic slice；Dust ring is around through-hole and concentric setting；Lid
Body lower surface is set there are three bottom boss, and around through-hole and mutually in 120 degree of angle arrangements, the line for constituting three is triangle.
Compared to existing technologies, the utility model neither influences the precision of client's assembling by the design of bottom boss,
Client can also be effectively improved and assemble yield, and the cost of mold processing can be reduced.
Detailed description of the invention
Attached drawing 1 is the perspective view at visual angle above the utility model embodiment；
Attached drawing 2 is the structural schematic diagram of the utility model embodiment lower surface.
In the figures above：1. flat lid；2. through-hole；3. upper surface；4. positioning column；5. hot molten column；6. dust ring；7.
