Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Fig. 2 is Fig. 1 cross-sectional schematic;
Fig. 3 is the structural representation of another preferred embodiment of the present invention;
Wherein: 1, main drive shaft, 2, driven shaft, 3, driving wheel, 4, bent axle, 5, slotted eye, 6, elastic component, 7, first permanent magnets, 8, second permanent magnets.
Embodiment
Combine accompanying drawing and preferred embodiment that the present invention is done further detailed explanation now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Shown in Fig. 1-2, a kind of electronic clock with snubber assembly comprises drive motor (not shown), main drive shaft 1, driven shaft 2 and pointer (not shown); Main drive shaft 1 and said driven shaft 2 coaxial settings; Said drive motor drives main drive shaft 1 rotates, and said driven shaft 2 is fixedly connected pointer, and said main drive shaft 1 drives driven shaft 2 and rotates; Be provided with snubber assembly between said main drive shaft 1 and the said driven shaft 2; Snubber assembly comprises and driving wheel 3 that is connected with main drive shaft 1 and the bent axle 4 that is connected with driven shaft 2 offers slotted eye 5 on the said driving wheel 2 that said bent axle 4 passes slotted eye 5 and is fixedly connected with driven shaft 2; Said bent axle 4 is connected through elastic component 6 with said driving wheel 3, and said elastic component 6 is preferably extension spring, torsion spring or straight spring.And slotted eye 5 is for being the deep-slotted chip breaker at center with main drive shaft 1.
Like Fig. 1, arc-shaped slot 5 is divided into A place and B place, and arc-shaped slot 5 is α by the A place to the corner at B place; At first bent axle 4 is parked in the B place of arc-shaped slot 5, and under the driving of driving wheel 3 at stepper motor, main drive shaft 1 drives driving wheel 3 and clockwise rotates; When driving wheel 3 clockwise rotates an angle [alpha]; Bent axle 4 contacts with the A place of arc-shaped slot 5, because action of inertia, bent axle 4 can't clockwise rotate at once; But under the effect of elastic component 6, clockwise rotate to the B place from the A of slotted eye 5 lentamente, thereby realize the stepping of stepper motor is driven to the level and smooth transmission of pointer.
As shown in Figure 3; Snubber assembly comprises a pair of first permanent magnets 7 that is connected with main drive shaft 1 and a pair of second permanent magnets 8 that is connected with driven shaft 2; Said first permanent magnets 7 forms closed magnetic circuits with second permanent magnets 8 and connects, when main drive shaft 1 is moved in the direction of the clock an angle by step motor drive after, and first permanent magnets 7 angle that moves in the direction of the clock; Because action of inertia; Driven shaft 2 can't be followed rotation at once, but under the traction of closed magnetic circuit, second permanent magnets 8 equal angular that moves in the direction of the clock lentamente; Drive driven shaft 2 equal angular that moves in the direction of the clock lentamente simultaneously, realize the stepping of stepper motor is driven to the level and smooth transmission of pointer.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the instructions, must confirm its technical scope according to the claim scope.
