The specific embodiment of reduction box 100 as shown in Figure 2, described reduction box 100 comprises planetary gearsets 110, first linkage gear 160, second linkage gear 170 and sun gear 180, the first described linkage gear 160 is coaxially connected with output shaft 12, the second described linkage gear 170 comprises gear wheel 171 and the pinion 172 of coaxial connection, described pinion 172 is meshed with the first linkage gear 160, the top of described planet carrier 112 is also provided with the planetary output gear 112b that can be meshed with gear wheel 171, three distributions triangular in shape are also installed in planet carrier 112 and can respectively relative to planet carrier 112 rotate planetary gear 112a, and the internal gear 111b that each planetary gear 112a is arranged with planetary ring gear 111 inwall is respectively meshed, described sun gear 180 comprises installation shaft 181 and the sun gear wheel 183 that is arranged in installation shaft 181 and sun pinion 182, planet carrier 112 is rotatable to be arranged in installation shaft 181 and sun pinion 182 is meshed with each planetary gear 112a simultaneously, described sun gear wheel 183 is meshed with the motor output gear 11a of motor 11, during auto state, hammerlock 2 stops that planetary ring gear 111 rotation makes motor 11 drive output shaft 12 to rotate, during manual mode, hammerlock 2 puts away planetary ring gear 111 and makes that planetary ring gear 111 can rotate under the drive of output shaft 12 and sun gear 180 is motionless.
The embodiment of output shaft 12 and the rocking arm 12c kind of drive as shown in Figure 7, described output shaft 12 is installed with horizontal bevel gear 12a, described horizontal bevel gear 12a is meshed with two vertical bevel gear 12b respectively, each vertical bevel gear 12b is installed with respectively and can drives by vertical bevel gear 12b the rocking arm 12c swung, each rocking arm 12c contacts with the push rod 301 of the execution switch 3 of automatic change-over respectively and connects, and described push rod 301 can be connected with the operating mechanism performing switch 3.Particularly, the mounting structure of the output shaft 12 of transmission mechanism 1 can have multiple implementation, one is preferably: described output shaft 12 is arranged on the pressing plate 130 of reduction box 100 in revolute pair mode, and the transversal line X-X that in axis Y-Y and Fig. 7 of output shaft 12, the rotating shaft line of two rocking arm 12c is formed vertically and intersect.Revolute pair described herein, refer to that output shaft 12 only has a rotational freedom after installing, it can adopt known structure to realize.The axis Y-Y also crossing structure vertical with described transversal line X-X of output shaft 12, the horizontal bevel gear 12a be fixed on output shaft 12 can be engaged with two vertical bevel gear 12b, but this engagement need meet following drive connection: described horizontal bevel gear 12a can only drive a rotation in two vertical bevel gear 12b in turn.The object setting up this drive connection is, automatic change-over can be made to realize aforesaid three kinds of operating states, and the concrete structure realizing this drive connection can have multiple, a kind of preferred structure is: described horizontal bevel gear 12a is the not all gear that driving cog distribution is less than or equal to half circumference; When two execution switches 3 are all in gate-dividing state, horizontal bevel gear 12a does not all engage with two vertical bevel gear 12b or all not exclusively engages; When horizontal bevel gear 12a engages completely with one of them vertical bevel gear 12b, then another vertical bevel gear 12b does not engage with horizontal bevel gear 12a.Should understand: when the driving cog distribution of horizontal bevel gear 12a is less than half circumference, when two execution switches 3 are all in gate-dividing state, horizontal bevel gear 12a does not all engage with two vertical bevel gear 12b, and namely the tooth of horizontal bevel gear 12a does not all contact with the tooth of two vertical bevel gear 12b, when the driving cog distribution of horizontal bevel gear 12a equals half circumference, when two execution switches 3 are all in gate-dividing state, horizontal bevel gear 12a not exclusively engages with two vertical bevel gear 12b, though namely the tooth of horizontal bevel gear 12a can contact with the tooth of two vertical bevel gear 12b, but the contact of whole tooth can not be realized, if rotate horizontal bevel gear 12a under the state that this not exclusively engages, then horizontal bevel gear 12a is while entering engage completely with one of them vertical bevel gear 12b, depart from another vertical bevel gear 12b and not exclusively engage (namely not engaging with another vertical bevel gear 12b).Thus, under two execution switches 3 are all in gate-dividing state, if rotate the handle 13 of automatic change-over as shown in Figure 8, horizontal bevel gear 12a can only drive a vertical bevel gear 12b to rotate, and two vertical bevel gear 12b can not be driven to rotate, thus stop the danger that two execution switches 3 close a floodgate simultaneously simultaneously.
Automatic change-over of the present invention is as described below at the transmission process of auto state and manual mode, when automatic change-over is arranged on auto state, sensitive switch 14 can by the position switch signal feedback of rocking arm 12c to controller 15, the catch 211 of hammerlock 2 locks planetary ring gear 111, motor 11 drives sun gear 180 active rotation, the passive rotation of planet carrier 112, planetary output gear 112b on planet carrier 112 drives the second linkage gear 170 to rotate, second linkage gear 170 drives the first linkage gear 160 to rotate thus output shaft 12 is rotated and drives to perform switch 3 action.When automatic change-over is arranged on manual mode, hammerlock 2 is allocated to position in the other direction by manpower, sensitive switch 14 can by the position switch signal feedback of rocking arm 12c to controller 15, the catch 211 of hammerlock 2 spins off from the boss 111a of planetary ring gear 111, planetary ring gear 111 is in rotatable free state, output shaft 12 is under the effect of manpower driving handle 13, the first linkage gear 160 is driven to rotate, first linkage gear 160 drives the second linkage gear 170 to rotate, second linkage gear 170 drives planet carrier 112 to rotate, sun gear 180 is connected with the motor output gear 11a of motor 11 simultaneously, because sun gear 180 bears the larger resistance of motor 11, therefore sun gear 180 transfixion, planetary ring gear 111 is only had to rotate, thus achieve the clutch of automatic change-over reduction box 100 when auto state and manual mode switch.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
