Embodiment Construction

[0040] see Figure 1 to Figure 2 As shown, the wiper device 200 includes a control module 6 and a wiper motor 100 . exist Figure 1 to Figure 2 A simplified circuit is shown in , and structures such as brushes, wiper linkages and wiper blades are omitted. The wiper motor 100 includes an armature 1 , a heat-sensitive component 2 and a motor housing 3 .

[0041] The armature 1 is a component that converts electrical energy into mechanical energy. When the armature 1 is energized, the armature 1 generates rotation for driving a wiper blade (not shown), and at this time the armature 1 has an internal resistance 10 .

[0042] The thermosensitive component 2 is connected in series between the power supply and the armature 1 . The heat-sensitive component 2 is also installed in the motor housing 3 , and when the wiper motor 100 heats up, the heat-sensitive component 2 will be heated and its temperature will rise. For example, the heat-sensitive component 2 is installed near the ...

Abstract

The invention provides a wiper device and a wiper motor. Wherein the heat-sensitive component connected in series between the power supply and the armature is in a first state when the temperature is lower than a threshold value and is in a second state when the temperature is higher than the threshold value, the heat-sensitive component is provided with a first resistor in the first state, and the heat-sensitive component is provided with a second resistor in the second state. And when the control module detects that the thermosensitive part is switched to the second state, the reset circuit is automatically and electrically connected with the power supply and the armature. Therefore, when the wiper motor has a high-temperature fault, the wiper device can continuously operate more safely, and the wiper blade is stopped at the stopping position.

Description

technical field [0001] The present application relates to a device for cleaning the windshield of a vehicle, in particular to a wiper device and a wiper motor thereof. Background technique [0002] When the wiper device of the vehicle windshield is working, the wiper motor drives the wiper arm through the transmission mechanism, and the wiper arm drives the wiper blade to wipe on the windshield to keep the glass clean. When it is necessary to stop the operation of the wiper device, the wiper device switches to the reset circuit. Under the control of the reset circuit, if the wiper blade is just at the docking position outside the windshield view, then the power supply of the wiper motor will be cut off to make the wiper The water motor stops working; if the wiper blade does not reach the parking position and is just in the view of the windshield, then it will continue to supply power to the wiper motor, so that the wiper motor will continue to work until the wiper blade reac...
