具体实施方式Detailed ways
下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
请参照图1所示，图1为本发明一种电动百叶窗用限位装置的结构示意图；于本实施例中，一种电动百叶窗用限位装置，包括上梁1，所述上梁1为中空结构，其内设置有用于驱动电动百叶窗的电机，所述电机的输出轴传动连接有传动轴，所述传动管10为螺杆，其与固定在上梁1内的螺栓11相配合，且传动管10为空心结构，其内过盈配合有内套管，所述内套管与传动轴键连接，且内套管与传动轴可相对滑动，所述传动管10上固定连接有限位块9，所述限位块9上螺纹连接有限位杆2，所述限位杆2与顶杆3配合的一端设置有顶块4，所述顶块4设置有一定弧度，所述上梁1上固定连接有支架6，所述支架6的下端连接有上限位微动开关7，且支架6的上端连接有下限位微动开关8，所述上限位微动开关7及下限位微动开关8均与控制器电连接，所述控制器与电机电连接，所述支架6上位于下限位微动开关8左端设置有用于顶压下限位微动开关8的顶杆4，所述顶杆4上套设有弹簧5。Please refer to Fig. 1, which is a structural schematic diagram of a limiting device for electric blinds according to the present invention; in this embodiment, a limiting device for electric blinds includes an upper beam 1, and the upper beam 1 is The hollow structure is equipped with a motor for driving electric blinds. The output shaft of the motor is connected to the transmission shaft. The tube 10 is a hollow structure with an interference fit inside the inner sleeve, the inner sleeve is keyed to the transmission shaft, and the inner sleeve and the transmission shaft can slide relative to each other, and the transmission tube 10 is fixedly connected with the limit block 9 , the limit block 9 is threadedly connected to the limit rod 2, and one end of the limit rod 2 and the push rod 3 is provided with a top block 4, and the top block 4 is provided with a certain radian. Fixedly connected with a support 6, the lower end of the support 6 is connected with an upper limit micro switch 7, and the upper end of the support 6 is connected with a lower limit micro switch 8, the upper limit micro switch 7 and the lower limit micro switch 8 They are all electrically connected to the controller, and the controller is electrically connected to the motor. The support 6 is located at the left end of the lower limit micro switch 8 and is provided with a push rod 4 for pushing down the lower limit micro switch 8. The push rod 4 Upper cover is provided with spring 5.
工作时：电机带动电动百叶窗的百叶帘上行，当电动百叶窗的百叶帘到达行程的上限位时，顶碰到上梁1下端的上限位微动开关7，上限位微动开关7将信号传递给控制器，控制器控制电机停止运作；电机带动电动百叶窗的百叶帘下行的同时，电机带动传动轴转动，传动轴转动带动内套管转动，从而带动传动管10转动，由于传动管10为螺杆，其与固定在上梁1内的螺栓11相配合，且传动管10内的内套管与传动轴可相对滑动，则传动管10转动的同时，又向右端移动，当电动百叶窗的百叶帘到达行程的下限位时，此时限位块9上的限位杆2端部的顶块3正好顶碰到顶杆4，使得顶杆4顶碰到下限位微动开关8，下限位微动开关8将信号传递给控制器，控制器控制电机停止运作。When working: the motor drives the venetian blinds of the electric blinds to go upward. When the venetian blinds of the electric blinds reach the upper limit of the stroke, they touch the upper limit micro switch 7 at the lower end of the upper beam 1, and the upper limit micro switch 7 transmits the signal to Controller, the controller controls the motor to stop operating; when the motor drives the blinds of the electric blinds down, the motor drives the transmission shaft to rotate, and the rotation of the transmission shaft drives the inner sleeve to rotate, thereby driving the transmission tube 10 to rotate. Since the transmission tube 10 is a screw, It cooperates with the bolt 11 fixed in the upper beam 1, and the inner sleeve in the transmission pipe 10 can slide relative to the transmission shaft, then the transmission pipe 10 rotates and moves to the right end at the same time, when the blinds of the electric blinds reach During the lower limit of the stroke, the top block 3 at the end of the limit rod 2 on the limit block 9 just hits the push rod 4, so that the push rod 4 bumps against the lower limit micro switch 8, and the lower limit micro switch 8 The signal is transmitted to the controller, and the controller controls the motor to stop.
