當人們生病時，總是希望能躺在一個舒適的病床上休養生息。病床的一個重要功能，是讓使用者能控制病床的傾斜程度，以使病人感覺舒服。也因此，推動病床以使病床傾斜的馬達裝置的安全性必須足夠，例如在病床傾斜角度到達極限時會自動停止，或是病床停止在某個傾斜角度時能非常穩固而不再晃動。When people get sick, they always want to lie on a comfortable bed to recuperate. An important function of the bed is to allow the user to control the tilt of the bed to make the patient feel comfortable. Therefore, the safety of the motor device that pushes the bed to tilt the bed must be sufficient, for example, when the bed tilt angle reaches the limit, or if the bed stops at a certain tilt angle, it can be very stable without shaking.

When the second switch unit S2 is in a closed state;
A.該第一電源接點P1連接24伏特直流電的正極，且該第二電源接點P2連接24伏特直流電的負極時，該繼電器單元K1吸合該第一接腳102及該第二接腳104短路，該馬達單元20正轉，該推桿單元30伸出。該馬達單元20正轉時，該第一電晶體單元Q1導通，電流路徑依序為該第一電源接點P1、該第二電晶體單元Q2、該第一馬達接點P3、該馬達單元20、該第二馬達接點P4、該第一電晶體單元Q1以及該第二電源接點P2。A.

When the motor unit 20 is rotating forward, the first transistor unit Q1 is turned on, and the current path is sequentially the first power contact point P1, the second transistor unit Q2, the first motor contact point P3, and the motor unit 20 The second motor contact P4, the first transistor unit Q1, and the second power contact P2.
B.該第一電源接點P1連接24伏特直流電的負極，且該第二電源接點P2連接24伏特直流電的正極時，該繼電器單元K1吸合該第一接腳102及該第二接腳104短路，該馬達單元20反轉，該推桿單元30縮回。該馬達單元20反轉時，電流路徑依序為該第二電源接點P2、該第一電晶體單元Q1、該第二馬達接點P4、該馬達單元20、該第一馬達接點P3、該第二電晶體單元Q2以及該第一電源接點P1。B. The first power contact P1 is connected to the negative pole of the 24 volt direct current, and the second power contact P2 is connected to the positive pole of the 24 volt direct current, the relay unit K1 attracts the first pin 102 and the second pin. 104 is short-circuited, the motor unit 20 is reversed, and the pusher unit 30 is retracted. When the motor unit 20 is reversed, the current path is sequentially the second power contact P2, the first transistor unit Q1, the second motor contact P4, the motor unit 20, the first motor contact P3, The second transistor unit Q2 and the first power contact P1.
2.當該第一開關單元S1於該推桿單元30的伸出極限時，該第一開關單元S1斷開；該繼電器單元K1釋放該第一接腳102及該第二接腳104的短路，使得該第一接腳102及該第二接腳104開路，並造成該第一接腳102及該第三接腳106短路；該第一馬達接點P3及該第二馬達接點P4短路造成該馬達單元20短路煞車。2. When the first switch unit S1 is at the extension limit of the pusher unit 30, the first switch unit S1 is turned off; the relay unit K1 releases the short circuit of the first pin 102 and the second pin 104. The first pin 102 and the second pin 104 are opened, and the first pin 102 and the third pin 106 are short-circuited; the first motor contact P3 and the second motor contact P4 are short-circuited. The motor unit 20 is caused to be short-circuited.
3.當該第二開關單元S2於該推桿單元30的縮回極限時，該第二開關單元S2斷開；該繼電器單元K1釋放該第一接腳102及該第二接腳104的短路，使得該第一接腳102及該第二接腳104開路，並造成該第一接腳102及該第三接腳106短路；該第一馬達接點P3及該第二馬達接點P4短路造成該馬達單元20短路煞車。3. When the second switch unit S2 is at the retracting limit of the pusher unit 30, the second switch unit S2 is turned off; the relay unit K1 releases the short circuit of the first pin 102 and the second pin 104. The first pin 102 and the second pin 104 are opened, and the first pin 102 and the third pin 106 are short-circuited; the first motor contact P3 and the second motor contact P4 are short-circuited. The motor unit 20 is caused to be short-circuited.
此外，當該第一電源接點P1及該第二電源接點P2斷電時，該繼電器單元K1釋放該第一接腳102及該第二接腳104的短路，使得該第一接腳102及該第二接腳104開路，並造成該第一接腳102及該第三接腳106短路；該第一馬達接點P3及該第二馬達接點P4短路造成該馬達單元20短路煞車。In addition, when the first power contact P1 and the second power contact P2 are powered off, the relay unit K1 releases the short circuit of the first pin 102 and the second pin 104, so that the first pin 102 The second pin 104 is opened, and the first pin 102 and the third pin 106 are short-circuited; the short circuit of the first motor contact P3 and the second motor contact P4 causes the motor unit 20 to short-circuit the brake.
斷電時的馬達發電效應會於該第二馬達接點P4產生正電壓，該第一馬達接點P3產生負電壓，此時該第一電晶體單元Q1可發揮隔離電壓的效果；否則馬達發電效應的電壓將由該第二馬達接點P4經由該第二開關單元S2回灌，該繼電器單元K1無法釋放該第一接腳102及該第二接腳104的短路；該第一接腳102及該第三接腳106開路，該第一馬達接點P3及該第二馬達接點P4無法短路，將造成該馬達單元20無法短路煞車。The motor power generation effect at the time of power failure generates a positive voltage at the second motor contact P4, and the first motor contact P3 generates a negative voltage. At this time, the first transistor unit Q1 can exert the effect of isolating the voltage; otherwise, the motor generates electricity. The voltage of the effect is recirculated by the second motor contact P4 via the second switch unit S2, the relay unit K1 cannot release the short circuit of the first pin 102 and the second pin 104; the first pin 102 and The third pin 106 is open, and the first motor contact P3 and the second motor contact P4 cannot be short-circuited, which will cause the motor unit 20 to be short-circuited.
另一種情況下，斷電時的馬達發電效應會於該第一馬達接點P3產生正電壓，該第二馬達接點P4產生負電壓，此時該第二電晶體單元Q2可發揮隔離電壓的效果；否則馬達發電效應的電壓將由該第一馬達接點P3經由該第一開關單元S1回灌，該繼電器單元K1無法釋放該第一接腳102及該第二接腳104的短路；該第一接腳102及該第三接腳106開路，該第一馬達接點P3及該第二馬達接點P4無法短路，將造成該馬達單元20無法短路煞車。In another case, the motor power generation effect at the time of power failure generates a positive voltage at the first motor contact P3, and the second motor contact P4 generates a negative voltage. At this time, the second transistor unit Q2 can exert an isolation voltage. The effect is that the voltage of the motor power generation effect will be recharged by the first motor contact P3 via the first switch unit S1, and the relay unit K1 cannot release the short circuit of the first pin 102 and the second pin 104; When the one pin 102 and the third pin 106 are open, the first motor contact P3 and the second motor contact P4 cannot be short-circuited, which will cause the motor unit 20 to be short-circuited.
本發明之該馬達驅動電路10係藉由該繼電器單元K1在該推桿單元30達到伸出極限或縮回極限，或斷電時將該第一馬達接點P3及該第二馬達接點P4短路以造成該馬達單元20短路煞車，藉以提高該馬達單元20的自鎖力；而正常供電且該推桿單元30未達到伸出或縮回極限時，解除該馬達單元20短路煞車；且能避免斷電後，該負載單元40（例如一病床）的重量推動該推桿單元30而產生的馬達發電效應造成該馬達單元20短路煞車不動作。The motor driving circuit 10 of the present invention uses the relay unit K1 to reach the extension limit or the retraction limit when the pusher unit 30 is reached, or the first motor contact P3 and the second motor contact P4 when the power is off. Short-circuiting to cause the motor unit 20 to short-circuit the brakes, thereby improving the self-locking force of the motor unit 20; and when the power supply is normal and the push rod unit 30 does not reach the extension or retraction limit, the motor unit 20 is released from being short-circuited; After the power failure is avoided, the motor power generation effect generated by the weight of the load unit 40 (for example, a hospital bed) pushing the pusher unit 30 causes the motor unit 20 to be short-circuited and does not operate.
綜上所述，當知本發明已具有產業利用性、新穎性與進步性，又本發明之構造亦未曾見於同類產品及公開使用，完全符合發明專利申請要件，爰依專利法提出申請。In summary, it is known that the present invention has industrial applicability, novelty and advancement, and the structure of the present invention has not been seen in similar products and public use, and fully complies with the requirements of the invention patent application, and is filed according to the patent law.
