Detailed description of the invention
Describe the detailed description of the invention of the application below in conjunction with the accompanying drawings in detail.
Fig. 1 to 3 display is according to the schematic diagram of the electric drive of a kind of detailed description of the invention of the application, and electric drive 100 includes mutually being installed together, by the first housing 11 and the second housing 12, the housing combined.Forming receiving space between first housing 11 and the second housing 12, driven pulley 31, crank 32, rocking bar 42 and connecting rod 5 are respectively positioned in receiving space.Armature 2 is fixedly mounted on the first housing 11, and the first axle 3 and the second axle 4 can be pivotally mounted to the first housing 11 respectively.Driven pulley 31 that on first axle 3, fixed plastics is made and the crank 32 that metal is made.The fixing rocking bar 42 being made of metal on the second axle 4.The rotary power of armature 2 output drives driven pulley 31 to rotate.Such as, as depicted, the output shaft of armature 2 and the basic setting in mutually perpendicular direction of the first axle 3, the output shaft of armature 2 arranges worm screw 20, driven pulley 31 is set to the worm gear engaged with worm screw 20, thus the high speed rotating of the output shaft of armature 2 can become the low speed rotation of the first axle 3.Crank 32 is configured to the parts separate with the driven pulley 31 being made up of injection mo(u)lding.It should be noted that independent only explanation crank 32 and both driven pulleys 31 are the components formed respectively, both can the most disconnected from each other not contact, it is possible to contacting with each other or being assembled in is fixed together.Owing to crank 32 is very big with the stress of driven pulley 31 and abrasion condition difference, manufactures both respectively and be conducive to according to circumstances selecting suitable material.For example, it is possible to manufacture that stressing conditions is more complicated but the crank 32 of simple in construction with the material of high-strength, high-anti-friction, and manufacture structure complexity with the plastics of easy molding but the fairly simple driven pulley 31 of stressing conditions.Such that it is able to reduction material cost, improve performance.
Connecting rod 5 has two articulated sections, and the two articulated section is articulated in crank 32 and rocking bar 42 respectively.The effective length of crank 32 is less than the effective length of rocking bar 42, and wherein effective length refers to the distance to the axis of its rotating shaft of the pivoting point with connecting rod 5.That is, the distance of the pivoting point of crank 32 and connecting rod 5 to the axis of the first axle 3 is less than the pivoting point distance to the axis of the second axle 4 of rocking bar 42 and connecting rod 5.Therefore, crank 32, rocking bar 42, connecting rod 5 and the first housing 11 form quadric chain, formed using crank 32 as driving member rocking bar 42 as the crank and rocker mechanism of driven member, by this crank and rocker mechanism can the rotary motion of the first axle 3 be changed into the second axle 4 at a range of reciprocating rotation less than 180 degree.
Crank 32 is fixed on the first axle 3 in the way of riveting.Such as, referring to shown in Fig. 4, the first axle 3 arranges and is positioned at the installation portion 35 of its end and is positioned at the boss 36 near installation portion 35, and crank 32 sets through hole 320, installation portion 35 inserts through hole 320, and boss 36 stops that crank 32 limits installation portion 35 and inserts the degree of depth of through hole 320.The end face extruding the first axle 3 makes the first axle 3 end expanding and riveting is in through hole 320.As shown in Figure 4, the end face at the first axle 3 also sets up and arranges the 37 of shrinkage pool vertically in axle, by extruding this position, is conducive to being expanded to surrounding by the end face of the first axle 3 and being fixed in described through hole 320.
In detailed description of the invention as shown in Figure 1, the first housing 11 arranges three mount points 15,16,17, and the first axle 3 and the second axle 4 are all to be pivotally mounted to the first housing 11.In other words, the first housing 11 is main load-carrying member, and the second housing 12 provides good for linkage and covers but be substantially not subject to the power of linkage.Therefore, the first housing 11 and the second housing 12 can be with the component manufactures of varying strength.
Above detailed description of the invention is merely to illustrate the application, and not restriction to the application, about the those of ordinary skill of technical field, in the case of without departing from scope of the present application, it is also possible to make a variety of changes and modification.The technical scheme of the most all equivalents falls within the category of the application, and the scope of patent protection of the application should be defined by the claims.
