Problems solved by technology
[0005] However, due to the characteristics of existing SMA materials, the problem of "extremely poor efficiency" severely limits the practicality of SMA drivers
And in an SMA working cycle, the contraction process of the SMA provides a large axial force to the outside world, but the stretching process not only provides no or very small force, but also takes up a large proportion of time
Therefore, how to increase the contraction ratio of the SMA to provide more useful work and increase the time ratio of the SMA working stroke to improve the efficiency of the SMA driver has become an important factor limiting the existing SMA driver

Embodiment
[0043] Such as figure 1 , figure 2 , image 3 As shown, the basic mechanical structure of the ultra-light silent engine is composed of a sinusoidal power drive mechanism, a one-way continuous transmission mechanism, and other auxiliary mechanisms such as the front panel 3 and the rear panel 6 that play a supporting role.
[0044] The sinusoidal power drive mechanism is located on the front of the front panel 3, including two shape memory alloy drive springs I and II, control plate 13 and motion conversion mechanism 15, and the shape memory alloy drive springs I and II are used as the power of the whole device The source is located symmetrically around the motion conversion mechanism 15 . The control pole plate 13 is vertically fixed below the front panel 6, and the lower ends of the two sets of driving springs are installed on the upper surface of the control pole plate 13 at the same time. current, and also serves as a mounting base for the two sets of drive springs. The...

The invention discloses an ultra-light silent engine, which is characterized in that it comprises a sinusoidal power drive mechanism, a one-way continuous transmission mechanism and other auxiliary devices. The sinusoidal dynamic driving mechanism is composed of two groups of shape memory alloy driving springs, a control plate and a motion conversion mechanism. The motion conversion mechanism is composed of swing fork, three sliding rods and semi-circular sliding rails. Two sets of driving springs are arranged on both sides of the motion conversion mechanism, and the two sets of driving springs are alternately expanded and contracted based on the 'memory' property of the shape memory alloy material. The motion conversion mechanism converts the alternate expansion and contraction of the twosprings into three sets of sinusoidal displacements which are only different in phase. The one-way continuous transmission mechanism is composed of crank and several bearings. The sinusoidal displacement produced by sinusoidal dynamic drive mechanism is converted into one-way continuous rotation of output shaft. The invention provides an ultra-light silent power generating device, which realizesthe function of converting linear displacement into one-way continuous rotation.
Description
technical field [0001] The invention relates to a novel power generating device and a motion converting actuator, more specifically a novel ultra-light ultra-quiet engine. Background technique [0002] With the development of electrical and electronic technologies, the demand for micro-power drives has exploded and has been widely used in various industries. In the military, miniature underwater reconnaissance submarines and miniature unmanned reconnaissance aircraft all use microdrives. In the medical field, micro-drivers are used to automatically adjust the driving of nursing beds and X-ray fluoroscopy beds, or implanted in patients to assist patients in completing normal physiological activities. In mechanical devices such as automobiles, the application of micro-drives is more frequent, such as the driving motor of the wiper, the driving motor of the lifting glass, and the driving motor of the electric seat. [0003] Microdrives are responsible for efficiently deliveri...
