Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any inventive step based on the embodiments of the present disclosure, shall fall within the scope of protection of the present application.
Referring to fig. 1-2, fig. 1 is a schematic view illustrating a state of use of a wiper device for a rearview mirror of an automobile according to an embodiment of the present disclosure; fig. 2 is a schematic structural view of a wiper device for a rearview mirror of an automobile according to an embodiment of the present disclosure. As shown in fig. 1-2, the automobile rearview mirror of the present specification includes a rearview mirror housing 100 and a mirror body 200 disposed within the rearview mirror housing 100.
This rain-scraping device includes: a drive unit 1, a wiper arm 2 and a wiper assembly 3. Specifically, the driving device 1 is disposed in the mirror housing 100 and located at the rear side of the mirror body 200; a through hole is formed between the lower side of the mirror body 200 and the rearview mirror housing 100, and a power output shaft of the driving device 1 penetrates through the through hole to be connected with the bottom end 21 of the wiper arm 2; the top end 22 of the wiper arm 2 is connected to the wiper blade assembly 3; the wiper blade of the wiper assembly 3 is attached to the outer surface of the mirror body 200; the driving device 1 is used for driving the wiper arm 2 to rotate so as to drive the wiper blade assembly 3 to rotate, so that a wiper blade of the wiper blade assembly 3 performs a wiping operation on an outer surface of the mirror body 200.
For example, the bottom end 21 of the wiper arm 2 may be a hollow cylinder, and an opening similar to an inverted "U" shape is formed between the lower side of the mirror body 200 and the lower edge of the mirror housing 100 as the through hole, and as an example, the size of the opening matches with the bottom surface of the cylinder of the bottom end 21 of the wiper arm 2, so that the bottom end 21 of the wiper arm 2 can pass through the opening and be clamped at the opening. As another example, the size of the opening is slightly smaller than the area of the bottom surface of the cylinder of the bottom end 21 of the wiper arm 2, so that the bottom end 21 of the wiper arm 2 is fastened at the opening. In either case, the cylindrical surface of the cylinder of the bottom end 21 of the wiper arm 2 abuts against the lower edge of the mirror housing 100.
Further, the driving device 1 comprises a motor 11 and a speed reducer 12 connected with a rotating shaft of the motor 11, and a power output shaft of the speed reducer 12 penetrates through the through hole to be connected with the bottom end 21 of the wiper arm 2. Specifically, the inside of the cylinder of the bottom end 21 is hollow, the inner surface of the cylinder may be designed to be a polygon, and accordingly, the power output shaft of the speed reducer 12 is set to be a shape matching the polygon, so that the power output shaft can drive the wiper arm 2 to rotate by rotating after being inserted into the inside of the cylinder. As an example, the motor 11 may be a dc permanent magnet motor, and the reducer 12 may be a planetary gear structure, such that the motor 11 is used as a power source, and the reducer 12 is used for reducing the rotation speed, increasing the torque, and transmitting the power of the motor 11 to the wiper arm 2 to drive the wiper arm 2 to rotate.
Alternatively, it is also possible to provide only one hole in the bottom of the mirror body 200, and then to fasten the bottom end 21 of the wiper arm 2 in the hole or to pass the bottom end 21 of the wiper arm 2 through the hole and to clamp the bottom end 21 in the hole, while the bottom end 21 of the wiper arm 2 is designed to be rotatable relative to the mirror body 21 or rotatable in the hole. In this way, the driving device 1 can drive the bottom end 21 of the wiper arm 2 to rotate only by providing power, and further drive the wiper arm 2 to swing back and forth.
Furthermore, the wiper assembly 3 comprises a wiper blade support, one side of which is hinged to the top end 22 of the wiper arm 2 and the other side of which fixes the wiper blade. Specifically, the wiper bracket is hinged to the top end 22 of the wiper arm 2, the wiper arm 2 is driven to swing in the swing process, and a wiper blade is fixed to the other side of the wiper bracket, and the wiper blade is a wiper film and attached to the mirror body 200, and when the wiper bracket swings, the wiper blade rubs against the outer surface of the mirror body 200, so that the mirror body 200 is cleaned.
When driving the vehicle in rainy day, can open this device of scraping rain, can clear away the ponding on rear-view mirror surface, keep the mirror surface not have ponding to keep normal back vision field of vision, reduce the risk that the traffic accident takes place.
In a possible embodiment, the wiper device further comprises a control module (not shown in the figures), which is connected to the driving device 1 via an electric wire and is configured to send a control signal to the driving device 1, wherein the driving device 1 is configured to drive the wiper arm 2 to rotate according to the control signal.
As an example, the control module is installed on a center console of an automobile, a corresponding control button can be arranged on the center console, when the mirror surface needs to be cleaned, a user can send a starting control signal to the driving device 1 through the corresponding control button, and the driving device 1 starts the motor 11 according to the control signal, so as to drive the wiper arm 2 to rotate; when the mirror surface does not need to be wiped, the user can send a stop control signal to the driving device 1 through the corresponding control button, and the driving device 1 turns off the motor 11 according to the control signal. The motor 11 of the driving device 1 may be a servo motor. In this example, the user may manually control the drive device 1 to start or stop.
As another example, the rain wiping device may further include a rain sensor (not shown in the drawings) mounted on the rearview mirror housing 100, the rain sensor being capable of detecting whether the outside of the vehicle is raining, the rain sensor being connected to the control module and configured to send detected outside rain data to the control module; the control module can judge whether to send a control signal to the driving device 1 according to the received external rainfall data. Specifically, two threshold values (such as a first threshold value and a second threshold value) may be preset, when the external rainfall data received by the control module exceeds the first threshold value, it is determined that the external rainfall is large, at this time, a start control signal is sent to the driving device 1, and the driving device 1 starts the motor 11 according to the start control signal, so as to drive the wiper arm 2 to rotate; in the process of rotation of the wiper arm 2, when the external rainfall data received by the control module is lower than the second threshold, it is determined that the external rainfall is small or the rainfall stops, at this time, a stop control signal is sent to the driving device 1, and the driving device 1 turns off the motor 11 according to the stop control signal. Regarding the first threshold and the second threshold, those skilled in the art can flexibly set according to actual needs, and this specification does not limit this.
