[0002] As we all know, the wiper is mainly used for wiping the front and rear windshields of the car. When the car is driving on a rainy day, the driver cannot see the road condition information behind the rearview mirror after the rain, which makes the car face a huge problem when turning or changing lanes. Security risks

Embodiment Construction
[0017] figure 2 Middle: 1 is the ACC gear of the car ignition switch. When it is turned on, the 12V (or 24V) DC is processed by the 7805 chip and outputs DC5V.
[0018] 6 is a triple switch, wherein K1 is a rearview mirror wiper control switch, when it is pressed, K1, K2, and K3 are connected simultaneously. K2 controls the on-off of the current flowing through the electromagnetic coil of the relay RELAY3. RELAY3 is a time-delay closing relay with a working voltage of DC12V. Its characteristics are: the moving contact is normally open before power is applied, and the moving contact is closed after being powered. 3, 4 are normally closed contacts, 3, 5 are normally open contacts, 3 is a changeover contact, connected to 7805 output terminal 3, when K2 is closed, DC12V working voltage is applied to both ends of the relay coil, and RELAY3 delays for a certain period of time After that, an action occurs, the normally closed contacts 3 and 4 are disconnected, the normally open co...

The invention relates to a linear reciprocating automotive rearview mirror wiper, relates to an automotive electric device which is capable of all-directionally wiping an automotive rearview mirror with no dead corner left, and solves the driving safety problem caused by the fact that the automotive rearview mirror is exposed to the rain in rainy days and is blurred. When a car is driven in rainy days, a driver cannot clearly see the road behind after the rearview mirrors are wet by the rain, and safety risks in car steering or lane changing are high. At present, only a top-level high-end limousine is equipped with rearview mirror wipers which are of rocker type, but all-directionally wiping the rearview mirrors is difficult for the rocker type rearview mirror wipers. In order to overcome the defects of the rocker type automotive rearview mirror wipers, direct-current motors are used to drive the wiper rubber strips to all-directionally wipe the mirrors with no dead corner left, by means of linear reciprocating.
Description
technical field [0001] The invention relates to automobile electrical equipment, in particular to an automobile rearview mirror wiper, which solves the problem of driving safety caused by unclear images after the automobile rearview mirror is sprayed with water in rainy days. Background technique [0002] As we all know, the wiper is mainly used for wiping the front and rear windshields of the car. When the car is driving on a rainy day, the driver cannot see the road condition information behind the rearview mirror after the rain, which makes the car face a huge problem when turning or changing lanes. Security risks. At present, only the top high-end luxury cars are equipped with rearview mirror wipers, and they are all rocker arm wipers. Generally, each rearview mirror has only one rocker arm, so for larger rectangular rearview mirrors, one rocker arm It is difficult for the windshield wiper to realize all-round wiping of the rearview mirror, such as the used rearview mir...
