Description
Technical field
The utility model relates to electronic device field, specifically refers to the ultra-thin VCM motor that a kind of buckle-type is installed.
Background technology
VCM is a kind of motor, and the magnetic field that it utilizes the electric current flowed in the voice coil loudspeaker voice coil of loud speaker to produce and the magnetic field that permanent magnet produces are to use the oscillating plate of loud speaker.The advantage of VCM is, it consumes less electric energy, small volume and cheap, it has very high precision in operation displacement (operationdisplacement), makes enough to use during its gap between the lens regulated in camera model and imageing sensor.
VCM motor has another name called voice coil motor, is mainly used in camera module, as the core executive component in optical, mechanical and electronic integration.Have and carry camera lens and pass through change current of electric and linear accurate moving lens function, thus realize Jiao far away of camera module, nearly burnt zoom function.
Complex process when VCM motor and chip assembly assemble in current industry, number of spare parts is many and cause module cost high; And motor height is higher, module height is caused usually to be greater than more than 4.2mm, thus restriction mobile phone thickness space, easily produce the foreign substance pollution such as rosin, tin sweat(ing) in welding, the higher phenomenon of module height.
Utility model content
The purpose of this utility model overcomes weak point of the prior art, provides a kind of and simplify production technology, ultra-thin VCM motor that the buckle-type that reduces costs is installed.
The purpose of this utility model is achieved through the following technical solutions:
The ultra-thin VCM motor that a kind of button is installed, comprise base, described base upper end face is provided with to electric terminal, described base upper end is provided with lower spring sheet, dust ring is provided with between described lower spring sheet and base, contact shell fragment electrode is arranged with outside described dust ring, carrier is provided with on the upside of described lower spring sheet, corner, described carrier upper end is ledge structure, described carrier outer surface is provided with coil, outside described coil, correspondence is provided with magnet, is provided with upper spring sheet on the upside of described magnet, is provided with shell on the upside of described upper spring sheet.
As the preferred technical scheme of the utility model, described upper spring sheet is connected in the enclosure with magnet pasting.
As the preferred technical scheme of the utility model, described base corner is fastening type structure.
As the preferred technical scheme of the utility model, described coil and lower spring sheet are welded to connect.
As the preferred technical scheme of the utility model, described lower spring sheet is connected with contact shell fragment electrode welding.
The utility model has the following advantages and beneficial effect compared to existing technology:
1, the utility model is by being designed to ledge structure by carrier upper end, cancels the plastic cement pad in traditional design, simplifies production technology, reduces costs, and is conducive to reducing the dust paid close attention to most in module simultaneously; Base 4 angle fastening type structures, rotate screens and fasten when installing with chip assembly in use, to be positioned on base plane to electric terminal and contact shell fragment electrode contact to electric; Motor changes spring-piece type contact elastic pressure with chipware Electrode connection into by original welding and contacts, the foreign matter such as rosin, dust class pollutant sources in effective minimizing welding, and production efficiency also significantly promotes; With the use of this structural electromotor, chip assembly can directly and the SMD implantation of cell phone mainboard, and module directly reduces FPC, socket, adds work simplification, and cost of labor declines, and the overall cost of whole module can decline 20%-30%.
2, dust ring design is adopted, both can effectively prevent dust from entering module imaging position, again can other position light of block resistance on the impact of imaging, after adopting this structure, motor effectively assembles height can accomplish 2.55+/-0.1mm, module overall height can accomplish 3.5mm, and module can be applicable to less setting height(from bottom), and it is thinner that mobile phone thickness can do.
