Detailed Description
The invention is described in more detail below with reference to the accompanying drawings. The utility model provides an electronic switch door gear with clutch, it includes main part 1 and the trigger 2 that movable hinge installs above that, is provided with accommodation groove 3 in the main part 1, installs pull rod 4 and brace 5 in the accommodation groove 3, pull rod 4 one end and trigger 2 movable hinge, the other end is articulated with brace 5, the brace 5 other end is movably placed in accommodation groove 3 through guide pin 6, accommodation groove 3 in still be provided with spring 7, spring 7 one end is connected with pull rod 4, the other end is connected with main part 1, its characterized in that: the main body 1 is also provided with an electric driving device, the electric driving device is connected with the brace 5 through a clutch device, and the electric driving device drives the brace 5 to move in the accommodating groove 3 through the clutch device, so as to indirectly drive the trigger 2 to swing.
The clutch device is a through hole 92 arranged at two sides of the connecting plate 9, an elastic boss 93 is arranged in the through hole 92, penetrates through the through hole 92 and protrudes out of the side wall of the connecting plate 9, and correspondingly: the brace 5 is provided with a first positioning hole 51, and the connecting plate 9 is arranged on the inner side of the brace 5 and enables the elastic boss to be clamped in the first positioning hole 51.
The electric driving device is an electric screw rod 81 driven by a gear motor 8, the electric screw rod 81 is in threaded connection with a threaded hole 91 in the connecting plate 9, and the other end of the connecting plate 9 is connected with the brace 5.
The elastic boss 93 is a dome boss arranged at two sides of the U-shaped plate 94, and the dome boss and the U-shaped plate 94 are integrally formed.
The inner side of the connecting plate 9 is provided with a mounting groove 95, two supporting legs of the U-shaped plate 94 are elastically mounted in the mounting groove, a positioning hole 96 is formed in the U-shaped plate, and a positioning pin 97 penetrates through the positioning hole 96 to be connected with the connecting plate 9.
The gear motor 8 and the main body are arranged through a motor frame 82, an electric screw 81 is fixed at the front end of the gear motor, and the electric screw 81 penetrates through the main body of the motor frame 82 and extends into the connecting plate 9.
The motor frame 82 is also provided with a limiting plate 83, the limiting plate 83 is provided with a limiting groove 84, and the electric screw 81 passes through the limiting groove 84 and is in threaded connection with the connecting plate.
The surface of the electric screw rod 81 is also sleeved with a retaining plate 85, and the retaining plate 85 is positioned between the limiting plate 83 and the motor frame main body.
Working principle: as shown in fig. 4, 5 and 6, the electric driving device is an electric screw 81 driven by a gear motor 8, the electric screw 81 is in threaded connection with a threaded hole 91 on a connecting plate 9, and the other end of the connecting plate 9 is connected with a brace 5.
