Description

Technical Field

[0001] The utility model relates to a curtain motor, in particular to an installation structure of a sensor for detecting the rotation angle of a curtain motor. Background Art

[0002] As a power source, motors are widely used in various mechanical devices. The rotating motor shaft can be converted into linear motion through transmission devices. Since the rotation angle of the shaft is proportional to the distance of linear motion, the distance of linear motion can be controlled by monitoring the rotation angle of the shaft. The curtain motor utilizes the above principle to control the distance that the motor pulls the curtain to move, thereby controlling the opening and closing degree of the curtain.

[0003] For existing curtain motors, in order to measure the rotation angle of the motor, a synchronous turntable is installed at the output end of the curtain motor. A plurality of through holes are evenly spaced on the outer edge of the turntable. The transmissive sensor for measuring the rotation angle is located on the upper and lower sides of the through holes. The through holes and the intervals between the holes alternately pass between the transmissive sensors, generating pulse signals to realize the measurement of the rotation angle, and accordingly controlling the curtain motor.

[0004] For existing curtain motors, the installation of their transmissive sensors usually requires a separate fixing bracket for fixing and needs to be connected to the control board through a separate cable. It not only has a complex structure, but also has high requirements for the installation accuracy of the sensor to ensure the measurement accuracy. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an installation structure of a sensor for a curtain motor that extends the installation position from the circuit board, so as to simplify the installation while improving its working stability and reliability.

[0006] The installation structure of the sensor of the curtain motor described in the utility model includes a turntable connected to the motor and rotating with the motor, as well as a sensor and a control board. A plurality of through holes are circumferentially spaced on the edge of the turntable. The plane of the control board is perpendicular to the rotating plane of the turntable. An extension board extends outward from the side of the control board and extends to the outside of the edge of the turntable. The sensor for measuring the rotation angle of the turntable is installed on the extension board and is opposite to the through holes on the edge of the turntable.

[0007] Furthermore, there is a fixed housing. The motor is fixedly installed in the housing. The turntable is arranged at one end of the housing and is connected to the motor. The control board is detachably installed on the side of the housing.

[0008] Furthermore, there is a gap between the edge of the turntable and the end of the housing. The sensor is a transmissive sensor, and the two detection ends of the transmissive sensor are respectively arranged on both sides of the edge of the turntable.

[0009] For the sensor installation structure of the curtain motor described in this utility model, the turntable can be directly connected to the rotating shaft of the motor, or can be connected through transmission devices such as gearboxes, speed reducers, and transmission rods, so that the turntable rotates with the motor, and the rotation speed of the motor rotating shaft is proportional to that of the turntable or is a specific value; at the same time, an extension plate for installing the sensor extends outward from the side edge of the control board to the edge of the turntable, so that the sensor does not need to set additional structural parts for installation and fixation, and the sensor no longer needs to be connected to the control board by cables, but is directly connected and conducted through pins on the extension plate of the control board. This can not only improve the installation strength of the sensor, avoid loosening, thereby improving its working stability, but also improve the convenience of installation and disassembly, and eliminate the need for wiring and its drawbacks.

[0013] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of this utility model.

[0014] It should be noted that if there are directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...) involved in the embodiments of this utility model, then the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0015] If there are descriptions involving "first" or "second" in the embodiments of the present utility model, such descriptions of "first" or "second" are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. Additionally, the technical solutions between various embodiments may be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0016] The present utility model provides a sensor mounting structure for a curtain motor.

[0017] The sensor mounting structure of the curtain motor in this embodiment includes a turntable 1 connected to the motor and rotating with the motor, as well as a sensor 2 and a control board 3. A plurality of through holes 11 are circumferentially spaced along the edge of the turntable. The plane of the control board is perpendicular to the rotating surface of the turntable. A extending board 31 extends outward from the side of the control board and extends to the outside of the edge of the turntable. The sensor for measuring the rotation angle of the turntable is mounted on the extending board and is opposite to the through holes on the edge of the turntable.

[0018] In the sensor mounting structure of the curtain motor, the turntable can be directly connected to the rotating shaft of the motor or can be connected through transmission devices such as a gearbox, a reducer, and a transmission rod, so that the turntable rotates with the motor and the rotation speed of the motor shaft and the turntable is proportional or a specific value. At the same time, the extending board for mounting the sensor extends from the side of the control board to the outside of the edge of the turntable, so that the sensor can be directly mounted on the extending board through pins without using wires.

[0019] In the sensor mounting structure of the curtain motor, there is a fixedly installed housing 4. The motor 5 is fixedly installed inside the housing. The turntable 1 is arranged at one end of the housing and is connected to the motor. The control board 3 is detachably installed on the side of the housing, thereby making the motor and the control board relatively fixed, further improving the connection strength between the turntable and the sensor, and thus improving the working stability and detection accuracy. There is a gap between the edge of the turntable 1 and the end of the housing 4. The sensor 2 is a through-beam sensor, and the two detection ends of the through-beam sensor are respectively arranged on both sides of the edge of the turntable. When the turntable rotates to the through hole and when it rotates to a position without a through hole, a change in the signal can be detected, thereby performing counting and calculating the rotation angle.
