The rearview mirrors of the vehicles such as the harvester, the harvester and the like in the field of agricultural machinery are arranged on the left top side and the right top side outside a cab, and the driver needs to stretch hands out of the cab when rotating the rearview mirrors, so that the operation is inconvenient. This scheme makes the rear-view mirror rotate angle regulation through electric putter's flexible through being connected electric putter between driver's cabin and rear-view mirror support. The electric push rod is controlled by a rocker switch arranged in the cab to stretch.
This scheme utilization rocker switch drive electric putter, electric putter promotes the rear-view mirror support, and the state as an organic whole is with the rear-view mirror to the rotation of rear-view mirror support drives the rear-view mirror and rotates to realize the angle modulation of rear-view mirror.
As shown in fig. 1 to 5, an electric drive device for a rearview mirror of a harvester comprises a rearview mirror 10, an electric push rod 20 and a rocker switch 30, wherein the rearview mirrors 10 are respectively installed on the left side and the right side of the top outside of a cab 40, each rearview mirror is arranged on a rearview mirror bracket and is integrated with the rearview mirror bracket, and the drive devices of the rearview mirrors are respectively installed in a group on the left side and the right side of the top inside of the cab.
The electric push rod 20 comprises a motor and a push rod, the motor drives the push rod to extend or retract, and when the motor shaft rotates in the positive direction, the push rod extends; when the motor shaft rotates reversely, the push rod retracts, the motor power supply of the electric push rod 20 is connected with the rocker switch 30 through a wire harness, and the rocker switch 30 is pulled up and down to drive the motor of the electric push rod 20 to rotate in the forward direction and the reverse direction. When the motor shaft of the electric push rod 20 rotates forwards, the push rod extends out; when the motor shaft rotates reversely, the push rod retracts. One end of the electric push rod 20 is connected to the top of the cab through a bracket, and the other end is connected to the rearview mirror bracket through a bracket. The rocker switch 30 provides positive and negative power to the motor shaft of the power push rod 20 to drive the push rod to extend and retract, and further push or pull back the rearview mirror support, so that the rearview mirror rotates clockwise or counterclockwise. When the rearview mirror rotates to a proper observation angle of a driver, the rocker switch is released, the rearview mirror stops rotating and stays at the proper angle.
In this embodiment, the rocker switch 30 is a self-reset switch, and the rocker switch includes three gears, i.e., a first gear, a second gear, and a neutral gear. When the rocker switch 30 does not drive the electric push rod 20, the rocker switch 30 is located at a neutral gear, a first gear on the rocker switch is marked as "front", a second gear on the rocker switch is marked as "back", and when the rocker switch is located "front" or "back", the electric push rod 20 is driven to extend or retract.
Eight terminal positions are arranged on the back of the rocker switch 30, the first to eighth terminal positions are respectively numbered as '1', '2', '3', '4', '5', '6', '7', '8', the eight terminal positions are respectively arranged on two sides of the back of the rocker switch, the terminals numbered as '1', '3', '5', '7' are arranged on one side, and the terminals numbered as '2', '4', '6', '8' are arranged on the other side;
the terminals numbered "3" and "4" are input terminals, and the terminals numbered "1" and "2" are output terminals;
the terminal with the number of "3" is connected with the positive pole of an external power supply, and the terminal with the number of "4" is connected with the negative pole of the external power supply;
the terminal numbered "1" and the terminal numbered "2" are connected to the motor input terminal of the electric putter 20.
When the rocker switch is in an original state, namely neutral, the first gear marked with the number 'front' is pressed, the terminals with the numbers '3' and '7' are conducted, and the terminals with the numbers '4' and '8' are conducted; when the first stage marked with "rear" is pressed, the terminals with numbers "3" and "1" are conducted, and the terminals with numbers "4" and "2" are conducted.
In order to enable the rocker switch 30 to control the positive and negative rotation output of the motor of the electric push rod 20, the terminals numbered 7 and 8 are not directly used for outputting power, but the terminals numbered 7 and 2 are connected through a lead, and the terminals numbered 8 and 1 are connected through a lead. Thus, the outputs of the terminals numbered "7" and "8" will be realized by the outputs of the terminals numbered "2" and "1", and the forward and reverse rotation control of the rocker switch 30 will be realized in contrast to the polarity of the power supply when the outputs are not directly output through the terminals numbered "7" and "8".
When the "front" position on the front side of rocker switch 30 is pressed, the terminals numbered "3" and "7" of rocker switch 30 are turned on, the terminals numbered "4" and "8" are turned on, the terminals numbered "7" and "2" are connected, and the terminals numbered "8" and "1" are connected, so that the terminal numbered "3" is the positive input of the power supply, the terminal numbered "4" is the negative input of the power supply, and the positive input is converted into the positive output of the terminal numbered "2", and the negative output of the terminal numbered "1" is converted into the negative output. The positive output of the terminal numbered "2" and the negative output of the terminal numbered "1" act on the motor input end of the electric push rod 20, and the motor shaft is driven to rotate forwardly.
Similarly, when the "rear" position on the front side of rocker switch 30 is pressed, the terminals "3" and "1" of rocker switch 30 are connected, the terminals "4" and "2" are connected, the terminal "3" is the positive input of the power supply, the terminal "4" is the negative input of the power supply, the positive output of the terminal "1" is converted into the negative output of the terminal "2". The positive output of the terminal with the number "1" and the negative output of the terminal with the number "2" act on the motor input end of the electric push rod 20, and the motor shaft is driven to rotate reversely to drive the rearview mirror 10 to rotate to a proper angle.
The rocker switch can be arranged at a position convenient to operate in the cab, and the rocker switch can be in different forms such as a knob type switch and a toggle switch.
This scheme uses electric putter to promote the rotation of rear-view mirror support, realizes the angle modulation of rear-view mirror, replaces traditional gear motor, bearing, axle bed, belt pulley, belt transmission structure such as belt, simple structure, and electric putter easily realizes the modularization. The rocker switch uses a unique wiring mode to realize the extension and contraction of the push rod. The telescopic push rod can be stretched out and drawn back without a controller and a relay, and the support is pushed to rotate, so that the angle adjustment of the rearview mirror is realized, the cost is low, and the realization is easy.
Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it is obvious for those skilled in the art to make other variations or changes based on the above descriptions, and all the embodiments cannot be exhausted here, and all the obvious variations or changes that belong to the technical solutions of the present invention are still in the protection scope of the present invention.
