Problems solved by technology

[0002] The existing motor-driven opening and closing curtains (opening and closing curtains) drive the opening and closing of the curtains through the operation of the motor. The existing electric curtain motors on the market sample the running speed of the motor. The low-speed signal, and then adjust the motor running speed, because the sampling is the low-speed signal of the motor, when the motor speed is found to be too high or too low to deviate from the predetermined standard speed through the sampling signal, the actual speed of the motor at this time has deviated greatly from the standard Rotational speed, resulting in low response speed of the automatic speed adjustment system of the motor, unable to adjust the speed of the motor in a timely manner. In addition, the opening and closing curtain motors used in the existing market use motors with a speed of 3000-5000 revolutions per minute , through two to three-stage reduction gears, a low speed of 80-120 revolutions per minute is obtained to pull the timing belt, thereby pulling the curtain
The existing motor adopts multi-stage deceleration, which causes the noise generated by the motor to increase significantly when it is in working condition. In daily life, most people are enduring the noise generated by the motor within the acceptable range. It is easy to cause people's hearing loss and affect people's quality of life

Embodiment 1

[0024] Such as Figure 1 ~ Figure 4 As shown, a curtain opening and closing motor includes a DC motor 1, a gear box 2 connected to one end of the output shaft 11 of the DC motor 1, wherein the gear box 2 is a first-stage gear box, and a motor speed signal sampling device 3, Wherein the motor rotational speed signal sampling device 3 is directly connected with the DC motor 1, and it includes a signal acquisition board 30 fixedly connected to the casing of the DC motor 1, specifically, two vertical positioning pins are fixedly arranged on the casing of the DC motor 1 10. The signal acquisition board 30 is provided with a positioning hole 300 corresponding to the size and shape of the positioning pin 10, and the signal acquisition board 30 is fixedly clamped on the casing of the DC motor 1 through the positioning hole 300 and the positioning pin 10. It also includes a signal generator 31 cooperating with the signal acquisition board 30 , the signal generator 31 is fixedly connect...

Embodiment 2

[0029] Such as Figure 5 ~ Figure 6 As shown, the present embodiment is basically similar in structure and principle to the above-mentioned embodiment 1, and the difference is that the signal acquisition board 30 includes an optical signal receiver 304, and an optical signal generating source 305 arranged in cooperation with the optical signal receiver 304, and a signal The generator 31 includes a rotating part 312 arranged between the optical signal generating source 305 and the optical signal receiver 304 and connected to the output shaft 11 of the DC motor 1. The rotating part 312 is in the shape of a fan blade, and several blades 3120 of the rotating part are arranged along the direction of the rotating part. The centers of 312 are uniformly distributed radially.

[0030] Such as Figure 7 As shown, when the DC motor 1 is running at high speed, the output shaft 11 of the DC motor 1 drives the signal generator 31 to rotate together, and at the same time, the optical signal...

Abstract

The invention provides an opening and closing curtain motor. The motor comprises a direct current motor, a reduction gearbox connected to an output shaft of the direct current motor and a motor rotating speed signal sampling apparatus. The motor is characterized in that the motor rotating speed signal sampling apparatus is directly connected to the direct current motor and comprises a signal acquisition plate fixedly connected to a direct current motor shell and a signal generator cooperatively arranged with the signal acquisition plate; the signal generator is connected to the output shaft of the direct current motor and can be freely rotated along with the output shaft; the signal acquisition plate is provided with a signal acquisition output line and a motor output line; the signal acquisition output line and the motor output line are connected to a microprocessor respectively. In the above technical scheme, an initial high speed signal of the motor is directly sampled and speed changes of the motor can be timely adjusted; and besides, through using PWM output modulation, noises are reduced.

Description

technical field [0001] The invention relates to a motor, in particular to a curtain opening and closing motor, which belongs to the technical field of "H02K motor" in the International Patent Classification Table. Background technique [0002] The existing motor-driven opening and closing curtains (opening and closing curtains) drive the opening and closing of the curtains through the operation of the motor. The existing electric curtain motors on the market sample the running speed of the motor. The low-speed signal, and then adjust the motor running speed, because the sampling is the low-speed signal of the motor, when the motor speed is found to be too high or too low to deviate from the predetermined standard speed through the sampling signal, the actual speed of the motor at this time has deviated greatly from the standard Rotational speed, resulting in low response speed of the automatic speed adjustment system of the motor, unable to adjust the speed of the motor in a...
