Referring to Fig. 1, the rosette 10 of the utility model embodiment is used for fingerprint recognition module 100.Rosette 10 wraps Include becket 12 and decorative layer 14.Becket 12 includes outer surface 122.Decorative layer 14 is by way of electrophoresis that electrophoretic paint is attached What is formed in the outer surface 122 of becket 12, the color of decorative layer 14 is identical with the color of electrophoretic paint.

In the rosette 10 of the utility model embodiment, decorative layer 14 is formed by way of electrophoresis, decorative layer 14 Color keep is the color of electrophoretic paint, rosette 10 is made any color, even white, will not or be not easy partially Yellow or other colors.

For example, when the color of electrophoretic paint is white, the color of decorative layer 14 is white；When the color of electrophoretic paint is red When, the color of decorative layer 14 is red；When the color of electrophoretic paint is golden, the color of decorative layer 14 is gold.

Certainly, the color of electrophoretic paint and decorative layer 14 is not limited to above-mentioned color, in other embodiments, electrophoretic paint and dress The color of circlets 10 can be other any colors, and the color of decorative layer 14 is identical with the color of electrophoretic paint.

In some embodiments, the color of decorative layer 14 is white, yellow, blueness or green.

In this way, contributing to the color of abundant rosette 10, user experience is lifted.

It is appreciated that the color of decorative layer 14 is not limited to above-mentioned color, and in other embodiments, the color of rosette 10 Can be other any colors, such as silver color, pink colour, grey etc..

In some embodiments, the outer surface 122 of rosette 10 includes the high smooth surface 1222 not covered by decorative layer 14.

In this way, making 10 beautiful beauty of rosette, user experience is lifted.

In the rosette 10 of the utility model embodiment, what decorative layer 14 was formed by way of electrophoresis, its thickness can To reach 10-15 μm, the intensity two that decorative layer can be greatly improved is not easily to fall off.And conventional physical deposition process (Physical Vapor Deposition, abbreviation PVD process) obtains latter usually only 0.4-2 μm of white decorative layer, its thing It is very poor to manage intensity, is easily scraped；In addition the thickness for the white decorative layer that anodic process flow obtains also only has in the prior art It is 6-10 μm, same easy to fall off, influence product appearance.

Specifically, the outer surface 122 of becket 12 is subjected to sanding and polishing processing, makes outer surface 122 that there is brighter gold Belong to gloss and form high smooth surface 1222.It is appreciated that high smooth surface 1222 remains as metal covering.

Decorative layer 14 can be made first to cover whole outer surface 122, then remove the decorative layer being covered in high smooth surface 1222 14 expose 122 part of outer surface of becket 12, then the part of the exposure of outer surface 122 to becket 12 carries out polishing formation High smooth surface 1222.It is of course also possible to when forming decorative layer 14, high smooth surface 1222 is reserved.

In some embodiments, rosette 10 includes basic ring 16 and radially outward prolonging from 16 lower end edge basic ring 16 of basic ring The flange 17 stretched, the upper end shape of basic ring 16 is along basic ring 16 into having the guide ramp 18 that radially-inwardly and tilts down, basic ring 16 Lateral surface and guide ramp 18 between form chamfering, the outer surface of chamfering is high smooth surface 1222.

In this way, high smooth surface 1222 is formed in chamfering so that 10 more beautiful beauty of rosette.

Specifically, rosette 10 is made of metal material, such as stainless steel so that rosette 10 have it is larger strong Degree.It is preferred that becket 12 is structure as a whole, so that 12 easy to manufacture of becket is molded.Becket 12 can pass through casting The mode made is molded, and material that can also be by way of machining on the part of place to go is formed.

In some embodiments, rosette 10 includes colourless protective layer 19, and colourless protective layer 19 covers 14 He of decorative layer High smooth surface 1222.

In this way, colourless protective layer 19 protects decorative layer 14 and high smooth surface 1222, decorative layer 14 and high smooth surface 1222 is avoided to grind Damage or be corroded.

Specifically, there is electrophoretic paint fracture in the junction of high smooth surface 1222 and decorative layer 14, easily falls paint when in use.And Becket 12 is exposed, and running into sweat of people etc. in use can be corroded, and easily discoloration blacks.Therefore, decorating Add one layer of colourless protective layer 19 on layer 14 and high smooth surface 1222, avoid decorative layer 14 and high smooth surface 1222 from directly being connect with external environment Touch, so as to be effectively prevented from that decorative layer 14 falls paint when in use and becket 12 is corroded.

It is appreciated that colourless protective layer 19 is transparent.

In some embodiments, colourless protective layer 19 is will to be formed in 14 He of decorative layer without colored paint by way of electrophoresis In high smooth surface 1222.

In this way, making 10 beautiful beauty of rosette, user experience is lifted.

In some embodiments, no colored paint paints for ultraviolet photo-curing.

So so that colourless paint rapid curing, and simple process and low cost, clean and effective.

Specifically, after no colored paint is formed in by way of electrophoresis in decorative layer 14 and high smooth surface 1222, then purple is passed through Outer linear light makes the irradiation of no colored paint no colored paint protective layer 19 that is cured to form that it doesn't matter.

In some embodiments, rosette 10 is made of metal material.

It can so cause rosette 10 that there is larger intensity.

In the utility model embodiment, rosette 10 is made of aluminium alloy.Certainly, in other embodiments, decorate Ring 10 can also be made of other metal materials, such as stainless steel.

In some embodiments, becket 12 is formed by way of casting.

Technique can so be simplified, reduce cost.
