Embodiment
Please refer to Fig. 1-Fig. 3, described potentiometer rotation control mechanism is used to realize the control to electrical equipment such as steer motor, when the rotary body of for example described potentiometer rotation control mechanism turns clockwise, can realize that the rotating speed of described steer motor clockwise rotates from slow to fast; When being rotated counterclockwise, can realize that the rotating speed of described steer motor rotates counterclockwise from slow to fast.
Described potentiometer rotation control mechanism comprises potentiometer 10, sensitive switch 20, rotary body 30, support 40.
Described potentiometer 10 is electrically connected on the circuit board 11, comprises that two are regulated an opposite adjustable resistance (not shown) and the potentiometer rotating shaft 12 of direction.Thereby described potentiometer rotating shaft 12 turns clockwise certain angle when returning from initial condition again, and the resistance of an adjustable resistance diminishes gradually and becomes big again and restore, and when being rotated counterclockwise, same variation also takes place the resistance of another adjustable resistance.Also be provided with in the described potentiometer rotating shaft 12 and described potentiometer rotating shaft 12 gears 13 coaxial, that described potentiometer resistance is changed because of rotation.
Described sensitive switch 20 also is electrically connected on the described circuit board 11, and is in series with the power supply (not shown) of a described potentiometer 10 and an electrical equipment.In the present embodiment, described electrical equipment is a steer motor, and then described potentiometer rotation control mechanism can be controlled the rotating speed of the break-make of described power supply and described steer motor simultaneously and turns to.Described sensitive switch 20 is push button, reed roller type, lever roller formula or short movable arm type sensitive switch.
Described rotary body 30 is the ship type, flexibly connects with described potentiometer rotating shaft 12.Edge, described rotary body 30 1 side is provided with the arc rack 300 with 13 engagements of described gear, and center, edge, another side is provided with and described sensitive switch 20 driving sections groove 301 inconsistent, become to be fade-in the cooperation that gradually goes out with the rotation and described sensitive switch 20 driving sections of described rotary body 30.Center, described rotary body 30 two sides is provided with two first parallel through holes 100.
Described support 40 is fixedly connected on described circuit board 11, is used for fixing described potentiometer 10, described rotary body 30 is rotationally connected.Described support 40 is provided with two and described first through hole, 100 corresponding second through hole 200.
Described support 40 comprises rotating shaft 401, through hole 402, reaches fixed part 403.
Described first through hole 100 and second through hole 200 be rotationally connected described support 40 and described rotary body 30 are passed in described rotating shaft 401.
Described through hole 402 is square, and is used for the described potentiometer 10 of clip.
Described fixed part and 403 described supports 40 are one-body molded, and suspension is in described through hole 402 tops, and the center is provided with the axis hole that adapts to described potentiometer rotating shaft 12.
Described support 40 also comprises flexible member 405, shank 406, host cavity 407 and lid 408.
Described flexible member 405 is spring or elastic strip.
Described shank 406 has a pair of, roughly is grenade-shaped, comprises resettlement section 406a and head 406b.Accordingly, described rotary body 30 two ends inwalls also comprise the integrated chute (not shown) that adapts with described head 406b that thicken gradually to bottom thickness from described rotary body 30 openings.Thereby when described rotary body 30 is rotated, the head 406b of described shank 406 can not become because of the distance of described head 406b and described rotary body 30 two ends inwalls far makes described flexible member 405 recovery natures lose elastic force, and then makes described two head 406b hold out against described rotary body 30 all the time.
Described resettlement section 406a is round barrel shape, and two corresponding described resettlement section 406a are the two ends of the described flexible member 405 of clip respectively, and described head 406b diameter holds out against described rotary body 30 two ends inwalls less than described resettlement section 406a when assembling.
Described host cavity 407 is hollow, is used to accommodate described flexible member 405 and shank 406.Two ends offer asymmetric opening, and the diameter of an end circular open and described head 406b diameter adapt; Other end bean sprouts shape opening is bigger, so that described flexible member 405 can vertically pass with described shank 406.
Described lid 408 is hollow, comprise one with the described head 406b diameter through hole that adapts so that the head 406b of described shank 406 can and described resettlement section 406a can not vertically pass.Described lid 408 integral body adapt with described bean sprouts shape opening, so that described host cavity 407 can seal after accommodating described described flexible member 405 that assembles and shank 406.After installing, described host cavity 407 sealings, the head 406b of a described shank 406 stretches out in described host cavity 407 bottoms, and the head 406b of described another shank 406 stretches out in described hollow lid 408.In another embodiment, described host cavity 407 two ends are described bean sprouts shape opening, all seal by described lid 408.
Described support 40 is made by heat sink material, is specially a fin, is used for heater element on the described circuit board 11 is dispelled the heat.
Because described two head 406b hold out against described rotary body 30 all the time, thereby described rotary body 30 can carry out elasticity around described rotating shaft 401 and can rotate with replying.Under the initial condition, described rotary body 30 two ends are subjected to the elastic force equilibrium of described two head 406b, and described groove 301 mediates, and does not touch the driving section of described sensitive switch 20.The user operates described rotary body 30 clockwise or when being rotated counterclockwise, described groove 301 rotates thereupon and departs from corresponding driving section, and then described driving section is touched in described rotary body 30 two sides, trigger described sensitive switch 20, the described potentiometer and the power supply of conducting series connection, the steer motor that connects described power supply is rotated to respective direction, and rotating speed is corresponding to change, during user's shut-down operation, described rotary body 30 is under the elastic force effect of described flexible member 405, return to initial position, described sensitive switch 20 also returns to initial position and cuts out, and closes the corresponding described steer motor of power supply and stops operating.
To sum up, the utility model embodiment is because adopted the rotary body 30 that has arc rack 300, with the technological means of potentiometer rotating shaft 12 by gear 13 transmissions, can only rely on folk prescription to the technical problem of going to transfer greatly or turn down the resistance of potentiometer so overcome, and then reached control flexibly, stable performance, compact conformation, the technique effect of reliable transmission.
The above is an embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection range of the present utility model.
