Fill the freedom degree of column limitation sliding block limiting cylinder 6.
Preferably, the sliding block 4 is sector.Sector structure volume is smaller.
It is lift, the Shi Weiwu lift annulus of t=0 when t > 0 if the axial displacement for just setting the groove unit rotation of cam is t
Slot is backhaul when t < 0.The corresponding corner value of three kinds of situations and the available different expection groove of the various combination of unit lift
21.When whole 180 degree corner designs of groove 21 are single lift or backhaul, available maximum torque increases multiple.
The sliding slot 72 that design inverts cam barrel 7 is just setting the circle number of the multi-turn groove 21 of cam if the corner of sliding slot 72 is set as θ
For k, then torque amplification factor m=k*180/ θ, output frequency are input frequency divided by k.For example individual pen groove just sets cam, inverts
72 corner of sliding slot of cam barrel is set as 10-18 degree, then peak torque amplification factor is 18-10 times；If multi-turn groove 21,
Then peak torque amplification factor is multiplied by circle number k.
This speed changer is precise space transmission mechanism, and motor drive is just setting the rotation of cam 2, just setting the groove on cam 2
21 curved surfaces push ball, and ball shuttling movement in groove 21, ball and sliding block 4 cooperate, in the through slot of sliding block limiting cylinder 6
Under 61 limitation, sliding block 4 makees straight reciprocating, and the straight pin 42 on sliding block 4 is located in the sliding slot 72 for inverting cam barrel 7,
Straight pin 42, which is stirred, inverts the swing rotation of cam barrel 7, and brush head 9, which is set in, to be inverted on cam cylinder, realizes erect brush.
The corresponding integral multiple just set 2 central axis circumference corner of cam and be 360 degree of groove 21 for just setting cam 2, is just setting cam 2
The corresponding sliding block 4 that rotates a circle moves back and forth a cycle, and this groove 21 for just setting cam is known as individual pen circulation, and so on more
Circle circulation.It is disconnected that 21 every 360 degree of the groove of multi-turn circulation can generate the discontinuous intersection of a single-point in lift and backhaul curve
Point, under the action of friction and inertia, spin 5 can pass through intersection breakpoint.The curved slot 21 of no inflection point sets this just
Cam 2 can be with steady operation.
Main support 3, sliding block limiting cylinder 6, gearbox case 8.Successively assembly is fixedly secured to one another integral.Cradle portion
Dividing is to couple the critical component just set cam 2, invert cam barrel 7 and sliding block 4, by the spacing block set for inverting cam barrel 7
71 reinforce inverting the intensity of cam barrel 7, and by the cooperation of spacing block set 71 and limit hole 31, limitation inverts the pendulum of convex block cylinder
Dynamic amplitude, main support 3 couple in input terminal with motor 1, the auxiliary bodies etc. such as can buckle with notch or add as needed.
Sliding block 4 and ball engagement are just being set cam 2 and are being coupled by ball with sliding block 4.It is sliding by the straight pin 42 on sliding block 4
The driving of block 4 inverts cam barrel 7.Sliding block 4 uses sector structure, and volume is minimum, can also using other step positioning and guidings or
Other shapes, ball can use other other rollers, straight pin 42 can also using taper pin, ball stud, telescopic pin etc. other
Equivalent unit.
The output end that cam barrel 7 is speed changer is inverted, suit brush head 9 executes vertical swing and brushes teeth thereon.If as
Functional speed changer, the sliding slot 72 for inverting cam barrel 7 can be designed to any fixed angle of 0-360 degree.As electric toothbrush
Output end, 72 angle of sliding slot are more conform with working condition requirement in 10-18 degree.The sliding slot 72 for inverting cam barrel 7 is the cylinder of sliding block 4
Pin 42 matches, for small angle tower sliding slot 72 used in electric toothbrush, can directly inside and outside wall is opened to simplify processing technology,
It will not be produced a very large impact to 7 rigidity of cam barrel is inverted.
The utility model is based on traditional Permanent magnet DC rotating electric machine and provides power, and 3000-8000 revs/min of motor speed,
Motor output torque 6-18 g.cm is converted by the movement of the mechanical transmission, realize be fixed on the toothbrush head of output end with
Output shaft reciprocally swinging within the scope of any one fixed design angle parameter of 10-18 degree, in the case where individual pen groove 21,
Hunting frequency is equal with motor output angular velocity, about 3000-8000 beats/min, bristle swing arc length at 2.5-4.5 millimeters,
It is 10-18 that torque, which increases maximum multiple, and 10 degree of whens are 10 times when be 18 times, 18 degree, and the curve that cam groove 21 is just being set in change is set
Meter can reduce multiple torque coefficient, realize that torque output about 50-160 g.cm sets numerical value.
The cam of just setting of speed changer is driving link in the implementation case, and inverting cam barrel is driven member, according to actually making
Cam barrel can will be inverted as driving link when sliding slot 72 is 360 degree of closed circulations with situation, and just setting cam is driven member.
A kind of erect brush electric toothbrush of the utility model is realized electronic by adding speed changer between motor 1 and output shaft
For the brush head 9 of toothbrush around axis direction reciprocally swinging, the utility model offers no inflection point cyclic curve groove on just setting cam 2
21, guarantee that the average rate of motor 1 rotates output, interior in a limited space, output torque is bigger, when groove 21 is individual pen, motor 1
Rotation one week, brush head 9 swing a cycle, and 9 hunting frequency of brush head is identical as rotational angular velocity.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
