Specific embodiment
The technical solution of the utility model is described in further detail with reference to specific embodiment.
The present embodiment proposes a kind of volume adjustment knob with damping structure, can be experienced during rotation mechanical
Resistance feedback, feel is finer and smoother.Its structure includes shell 5, encoder 6, rotating shaft 4, runner 1, spring 3 and slide bar 2.
The shell 5 is agent structure, is provided with through inside and outside through hole, is being uniform on the circumference of R apart from the through hole center of circle
Multiple cylindrical grooves are distributed with.The encoder 6 is located at the inside of the shell, for adjusting volume.The outside of the runner 1
Dicoration is played in face, and the centre of medial surface is connected with the rotating shaft 4；The rotating shaft 4 passes through logical on the shell 5
Hole, and be connected with the encoder 6.When rotating wheel, axis of rotation described in the driven by rotating wheel, the rotating shaft will rotate to be believed
Encoder number is passed to, the encoder carries out volume adjusting after receiving rotating signal.
In order to strengthen the damping and amortization of the volume adjustment knob, the present embodiment is provided between the shell 5 and runner 1
Spring 3 and slide bar 2, one end of the spring are fixed in the cylindrical groove of the shell, other end connection slide bar；The slide bar
The other end be provided with hemispherical projections, the hemispherical projections of the slide bar 2 are contacted with the medial surface of the runner 1, with runner 1
Circular-rotation, the contact surface of the runner 1 and slide bar 2 forms a circumference 11, and the radius of the circumference 11 is R.The circle
All 11 isodiametric hemispherical dimples by being sequentially connected are constituted, therefore, the center of circle of the runner upper half spherical pit with it is described
The distance in the runner center of circle is R.The shape of the pit is engaged with shape raised on the slide bar, and the pit center
Line is vertical with the end face of knob, and the center line of the slide bar is vertical with the end face of knob.
Used as preferred embodiment, the outer surface of the runner 1 sets decorative pattern, is conducive to increasing between finger and runner 1
Friction, comfort and operability of the raising when using, while the outward appearance appreciating of product can be improved.In addition, can be described
Axle sleeve 7 is set on the outer surface that rotating shaft 4 is contacted with outer casing through hole, and the axle sleeve 7 is preferably quality of rubber materials, for increasing rotating shaft 4
With the friction of the through-hole surfaces of shell 5, viscous sense during turn is improved.In addition, can be connect with the cylindrical groove of shell 5 in the slide bar 2
Lubricant is coated on tactile outer surface, the friction between slide bar and cylindrical groove body wall can be reduced.
In order to improve fine and smooth sense during 1 turn of runner, the radius of pit should be small as far as possible, and the quantity of pit is as far as possible
It is many, therefore the center of circle of runner episphere pit is close to the cylindrical of runner as far as possible.Preferred pit radius r≤2.5mm, pit
Quantity be M, M=2i, i are the natural number more than zero, preferred i >=2, further preferred i >=5.In addition, the slide bar
Quantity for N number of, be evenly distributed on circumferentially, N=2j, j is the natural number more than zero, and j≤i；Adjacent slide bar center
The angle of line is β degree, and β meets following relation：β=180/j.
When using, rotating wheel 1, because runner 1 is fixed together with rotating shaft 4, rotating shaft 4 is connected with encoder 6, rotating shaft 4
The spinning movement that runner 1 is received can be delivered to and volume adjusting is realized on encoder.Simultaneously because runner 1 is contacted with slide bar 2, it is sliding
Bar 2 is connected with spring 3, and spring 3 is limited in the cylindrical groove of shell 5, and spring 3 produces negative side because of the extruding by runner 1
To active force, the active force causes that the hemispherical projections at the top of slide bar 2 are against in the hemispherical dimples of runner 1 all the time.Work as rotation
During Rotating wheel 1, the hemispherical projections at the top of slide bar 2 are rotated in the hemispherical dimples of runner 1, therefore are that the thrust of spring makes cunning
Bar 2 and runner 1 can experience resistance during frictional force, staff rotating wheel 1 are produced in rotary course, produce damping
Sense.When staff is rotated to be stopped, the frictional force existed between slide bar 2 and runner 1 can be such that runner rotation stops at once, it is ensured that volume
The accuracy of adjustment.The volume adjustment knob of the present embodiment has damping structure, enhances the viscous sense of adjusting knob, operation side
Just, also failure is not lived, and be can be used on the lossless music player of high definition, it is also possible to have this kind of electronic product of volume knob at other
On.
Above example is only several in the several preferred embodiment of the utility model, it is noted that this practicality is new
Type is not limited to above-described embodiment；For the person of ordinary skill of the art, still can be to described in previous embodiment
Technical scheme is modified, or carries out equivalent to which part technical characteristic；And these modifications or replacement, do not make phase
Answer the spirit and scope of essence disengaging the utility model technical scheme required for protection of technical scheme.
