Embodiment approach

[0052] Figure 1a One embodiment of the invention is shown in the form of:

[0053] The basic mechanical structure of the new ultra-light silent driver is composed of a power generating mechanism, a "T"-shaped swing mechanism 12, and a movement direction maintaining mechanism 6. The power generating mechanism is composed of a shape memory alloy driving wire I 1 and a shape memory alloy driving wire II 11 And its corresponding control electrode 10 composition, based on the "memory" effect of SMA, when the shape memory alloy driving wire is heated and cooled by a certain frequency through the control electrode 10, the shape of the wire changes and stretches and contracts periodically, while the shape One end of the memory alloy drive wire is connected to the control electrode 10, and the other end is connected to the two lugs of the slider 2 respectively, so as to control the shape memory alloy drive wire I and II to elongate and contract alternately, so as to pull the slider 2 t...

Abstract

The invention discloses a novel ultra-light ultra-silent driver, which comprises a power generating mechanism, a swinging mechanism and a moving direction maintaining mechanism. The power generating mechanism comprises at least two shape memory alloy driving wires and respective electrodes thereof. The two shape memory alloy driving wires are directly or indirectly connected to both sides of the swinging mechanism respectively, and can be alternately stretched and retracted under the control of a control electrode to drive the swinging mechanism to swing left and right. The moving direction maintaining mechanism is connected to the swinging mechanism, and transfers the left and right swing as the rotation direction required by the output shaft at the end of the moving direction maintainingmechanism. The novel ultra-light ultra-silent driver realizes a function of converting linear translation or swing into smooth rotation.

Description

technical field [0001] The invention relates to a novel power generating device and a motion conversion variable speed mechanism, more specifically a novel ultra-light and ultra-quiet driver. Background technique [0002] Commonly used conventional micro power drives are varied and widely used. The micro-drivers used in automobiles include wiper drive motors, lift glass drive motors, and electric seat drive motors. They are used in the medical field for patients' automatic adjustment nursing beds and X-ray perspective beds. In the military field, they are used for micro underwater detection. Submarines use microdrives. The role of these tiny drives is to efficiently power the machine. Among them, the representative one is the motor. Its basic components include rotor, rotor winding, stator, stator winding and base, etc. The complex structure makes it heavy and costly, which is in line with the lightweight design concept of the machine. violated. Moreover, there are unavo...
