Description
本發明係關於一種驅動系統，尤指一種結構簡單、組裝便捷、堅固耐用、散熱效果佳與高致動力或高負載能力之高致動力壓電驅動系統。The invention relates to a driving system, in particular to a high-power piezoelectric driving system with simple structure, convenient assembly, sturdy and durable, good heat dissipation effect and high power or high load capacity.
習用驅動系統，如I289468(2007/11/11中華民國發明專利公告案)或Jwo-Ming,Jou and Kai-Lin,Huang,“Miniature Piezoelectric Motor-Trolley”,Proceedings of ICAST2006：17th International Conference on Adaptive Structures and Technologies pp.380~387,(2006/10/16~19,Taiwan)、Jwo-Ming,Jou and De-Yang,Dai,“A Study for the Piezoelectric Motor-Trolley Driving Way”,Journal of the Chinese Society of Mechanical Engineers,Vol.27,No.6,pp.639~645(2006,Taiwan)或Jwo-MingJou,“A Study on the H Type Piezoelectric car”,International Conference on Electric Information and Control Engineering,ICEICE 2012,IEEE publication(Accepted,2012/04/06-08,Lushan of China)所述之壓電驅動系統或稱為壓電車。其中以I289468(2007/11/11中華民國發明專利公告案)或Jwo-Ming,Jou and Kai-Lin,Huang,“Miniature Piezoelectric Motor-Trolley”,Proceedings of ICAST2006：17th International Conference on Adaptive Structures and Technologies pp.380~387,(2006/10/16~19,Taiwan)、Jwo-Ming,Jou and De-Yang,Dai,“A Study for the Piezoelectric Motor-Trolley Driving Way”,Journal of the Chinese Society of Mechanical Engineers,Vol.27,No.6,pp.639~645(2006,Taiwan)所述之壓電驅動系統或壓電車， 其係由座體、壓電馬達、被動元件與驅動電路等構件所組成，其中，該壓電馬達與被動元件係結合於該座體以分別傳遞與提供行駛動力，該壓電馬達具有用以提供動力之壓電定子、抵住該壓電定子以傳遞動力之轉子、用來保持該壓電定子與轉子之軸桿、用來提供預應力予該壓電定子及轉子之彈性元件、以及用來定位限制該轉子之限制元件，且該壓電馬達可透過驅動電路輸出動力，讓壓電車在軌道或地面上行駛。惟構成該種壓電車之主要結構與元件卻過於繁複與眾多，如1289468第7圖所揭露之主要元件與細部元件，包括金屬管、壓電陶瓷片、轉子、軸桿、彈性元件、限制元件、墊片、螺絲帽、傳動元件、軸承、鋼圈、齒輪、軸承、軸桿、鋼圈、前固定座、導電片與後固定座等不下十幾種之多。由於構件過於繁複與眾多，使得該壓電車在組裝時顯得非常困難；除了增加製造成本之外，品質的不穩定性也相對的增加。另外，從壓電定子所傳送出來的機械能，再透過齒輪組將能量傳輸到鋼圈與軌道；讓輸出的機械能再次的損耗，使得該壓電車之整體輸出效能大為降低。再者，構成該座體之前固定座、導電片與後固定座係為塑膠材質或絕緣材質，使得壓電定子在驅動中所產生之高溫或高熱，無法透過座體來散熱。此種高溫或高熱的現象，除了可能會改變壓電定子之驅動條件之外，也可能會改變固定壓電定子之邊界條件；亦即會降低壓電定子之振動幅度以及降低轉子之轉速。Conventional drive systems, such as I289468 (2007/11/11 Republic of China invention patent announcement) or Jwo-Ming, Jou and Kai-Lin, Huang, "Miniature Piezoelectric Motor-Trolley", Proceedings of ICAST2006: 17th International Conference on Adaptive Structures And Technologies pp.380~387, (2006/10/16~19, Taiwan), Jwo-Ming, Jou and De-Yang, Dai, “A Study for the Piezoelectric Motor-Trolley Driving Way”, Journal of the Chinese Society Of Mechanical Engineers, Vol. 27, No. 6, pp. 639~645 (2006, Taiwan) or Jwo-MingJou, "A Study on the H Type Piezoelectric car", International Conference on Electric Information and Control Engineering, ICEICE 2012, The piezoelectric drive system described in IEEE publication (Accepted, 2012/04/06-08, Lushan of China) is called a piezoelectric vehicle. Among them, I289468 (2007/11/11 Republic of China invention patent announcement) or Jwo-Ming, Jou and Kai-Lin, Huang, "Miniature Piezoelectric Motor-Trolley", Proceedings of ICAST2006: 17th International Conference on Adaptive Structures and Technologies pp .380~387,(2006/10/16~19,Taiwan),Jwo-Ming,Jou and De-Yang,Dai,"A Study for the Piezoelectric Motor-Trolley Driving Way",Journal of the Chinese Society of Mechanical Engineers Piezoelectric drive system or piezoelectric vehicle described in Vol. 27, No. 6, pp. 639~645 (2006, Taiwan), The utility model is composed of a member such as a seat body, a piezoelectric motor, a passive component and a driving circuit, wherein the piezoelectric motor and the passive component are coupled to the base body to respectively transmit and provide driving power, and the piezoelectric motor has a a powered piezoelectric stator, a rotor that resists the piezoelectric stator to transmit power, a shaft for holding the piezoelectric stator and the rotor, an elastic member for providing pre-stress to the piezoelectric stator and the rotor, and The positioning device limits the limiting element of the rotor, and the piezoelectric motor can output power through the driving circuit to allow the piezoelectric vehicle to travel on the track or the ground. However, the main structures and components constituting such a piezoelectric vehicle are too complicated and numerous, such as the main components and detailed components disclosed in FIG. 7 of 1289468, including metal tubes, piezoelectric ceramic sheets, rotors, shafts, elastic members, and limiting members. , gaskets, screw caps, transmission components, bearings, steel rings, gears, bearings, shafts, steel rings, front mounts, conductive sheets and rear mounts are no less than a dozen. Due to the complexity and numerous components, the piezoelectric vehicle is very difficult to assemble; in addition to increasing manufacturing costs, the quality instability is relatively increased. In addition, the mechanical energy transmitted from the piezoelectric stator is transmitted to the steel ring and the track through the gear set; the mechanical energy of the output is again lost, so that the overall output performance of the piezoelectric vehicle is greatly reduced. Furthermore, before the base body is formed, the fixing seat, the conductive piece and the rear fixing seat are made of a plastic material or an insulating material, so that the high temperature or high heat generated by the piezoelectric stator during driving cannot be dissipated through the base body. Such high temperature or high heat phenomenon may change the boundary condition of the fixed piezoelectric stator in addition to changing the driving condition of the piezoelectric stator; that is, the vibration amplitude of the piezoelectric stator and the rotation speed of the rotor may be lowered.
再者，如Jwo-Ming Jou,“A Study on the H Type Piezoelectric car”,International Conference on Electric Information and Control Engineering,ICEICE 2012,IEEE publication(Accepted,2012/04/06-08,Lushan of China)所述之壓電驅動系統或稱為壓電車，雖然已改善上述相對之缺點，惟其致動力或負載能力確無法大幅的提升；且其基座上所貼附之壓電陶瓷片容易破裂。Furthermore, such as Jwo-Ming Jou, "A Study on the H Type Piezoelectric car", International Conference on Electric Information and Control Engineering, ICEICE 2012, IEEE publication (Accepted, 2012/04/06-08, Lushan of China) The piezoelectric drive system, or piezoelectric vehicle, described above has improved the above-mentioned relative disadvantages, but its power or load capacity cannot be greatly improved; and the piezoelectric ceramic sheets attached to the base are easily broken.
綜上所述之壓電驅動系統或壓電車，其所存在之相對缺點，如下：In summary, the relative disadvantages of the piezoelectric drive system or the piezoelectric vehicle are as follows:
(1)主要元件與細部元件過於繁複，致使組裝不易，徒增製造成本；(1) The main components and the detailed components are too complicated, resulting in difficulty in assembly and increasing manufacturing costs;
(2)能量轉換元件過多，致使摩擦力大增，進而導致壓電車之整體輸出效率降低；(2) Excessive energy conversion components cause a large increase in friction, which in turn leads to a decrease in the overall output efficiency of the piezoelectric vehicle;
(3)座體設計不良，致使壓電定子無法即時散熱，可能導致壓電車之行駛速度降低或無法行駛。(3) The design of the seat is poor, resulting in the piezoelectric stator not being able to dissipate heat immediately, which may cause the speed of the piezoelectric vehicle to be reduced or unable to travel.
(4)致動力低或負載能力低，無法驅動較重之光機電傳動機構或系統。(4) Low actuation force or low load capacity, unable to drive heavy optical electromechanical transmission mechanisms or systems.
(5)基座上所貼附之壓電陶瓷片容易破裂。(5) The piezoelectric ceramic sheets attached to the susceptor are easily broken.

It has been experimentally proved that the load capacity of the high-powered piezoelectric drive system of the present invention is much higher than that of the conventional piezoelectric drive system (about 1.7 times) under the same driving voltage.
