The present invention relates to the technical field of automobile parts, and particularly to an automobile interior rearview mirror.
Automobile rearview mirrors are located at both left and right sides of an automobile head portion and at a front position inside the automobile. The rearview mirrors at both left and right sides of the automobile head portion can reflect circumstances at the sides of and underneath the automobile; and the rearview mirror at the front position inside the automobile, i.e. automobile interior rearview mirror, can reflect the circumstances behind and inside the automobile. Among these, the automobile interior rearview mirrors can be classified into common rearview mirrors and anti-glare rearview mirrors; and the common rearview mirrors are generally plane mirrors, while the anti-glare rearview mirrors usually consist of a mirror with a glass comprising an electrically conductive layer, two photosensitive diodes, and an electronic controller.
At present, the automobile interior rearview mirrors from the market also can be classified into electronic function type and non-electronic function type; the automobile interior rearview mirrors of the electronic function type usually have keys for performing corresponding function conversion in order to ensure that various electronic functions can be realized. In the prior art, the above keys of the automobile interior rearview mirrors of the electronic function type may be touch keys; specifically, the touch key may include: a PCB board located below a rearview mirror glass, and a copper sheet provided at a corresponding area on the PCB board. In the use process, when a human hand touches the rearview mirror glass, a varying capacitive effect is formed between a finger and the copper sheet on the PCB board, so that the object of controlling the automobile interior rearview mirror of the electronic function type to execute a relevant command can be achieved.
However, the inventor of the present application found that since the glass of the anti-glare rearview mirror comprises the electrically conductive layer, the finger and the copper sheet on the PCB board will be insulated by this electrically conductive layer, thus it is impossible to form the varying capacitive effect, and further it is impossible to realize touch screen operations, that is, the automobile interior rearview mirrors in the prior art usually cannot simultaneously have the anti-glare function and the touch key operation function.
An object of the present invention is to provide an automobile interior rearview mirror so as to solve the problem that the automobile interior rearview mirrors in the prior art usually cannot simultaneously have the anti-glare function and the touch key operation function.
The present invention provides an automobile interior rearview mirror, including: a front frame, a corresponding PCB key strip provided below the front frame, and a glass mirror provided below the PCB key strip, wherein the PCB key strip is provided thereon with at least one PCB touchpad, and each of the at least one PCB touchpad is provided thereon with a metal sensor sheet; and the metal sensor sheet is connected with a rearview mirror CPU by a bonding pad via a leading wire.
In the above, the front frame is a plastic frame.
Specifically, the glass mirror is a plane mirror or an anti-glare mirror.
Further, a light strip is provided below the glass mirror, the light strip is provided with hidden characters; the light strip is provided at an inner side of the PCB key strip, and the hidden characters are provided to be corresponding to the PCB touchpad; when a human hand touches the front frame, the hidden characters are lightened; when the human hand does not touch the front frame for a long period of time, the lightened hidden characters disappear.
Preferably, the PCB key strip is provided with a plurality of the PCB touchpads, and each of the PCB touchpads is provided with the metal sensor sheet; the PCB touchpads are able to be used to be corresponding respectively to different instruction inputs.
In actual application, a rear housing is provided below the light strip, and the rear housing is in butt joint with the front frame.
In the above, the rear housing is provided with universal serial bus (USB) interfaces.
Specifically, a screen and a PCB board are provided between the light strip and the rear housing, and the screen is provided to be located above the PCB board. When a human hand touches the front frame, the screen can display the hidden characters in an on screen display (OSD) manner; when the human hand does not touch the front frame for a long period of time, the lightened hidden characters disappear.
Further, an upper supporting plate is provided above the PCB board, and the upper supporting plate is provided to be located below the screen; a lower supporting plate is provided below the PCB board, and the lower supporting plate is provided to be located above the rear housing.
Preferably, the rear housing is connected with a fixed support.
With respect to the prior art, the automobile interior rearview mirror in the present invention has the following advantages:
the automobile interior rearview mirror provided in the present invention includes: the front frame, wherein the corresponding PCB key strip can be provided below the front frame, the glass mirror can be provided below the PCB key strip; the above PCB key strip can be provided with the PCB touchpads, each of the PCB touchpads can be provided with the metal sensor sheet; the metal sensor sheets can be connected with the rearview mirror CPU by the bonding pad via the leading wire. Thus, it can be seen from analysis that for the automobile interior rearview mirror provided in the present invention, the PCB key strip having the PCB touchpads and the metal sensor sheets is provided between the front frame and the glass mirror, i.e. the PCB key strip is disposed above the glass mirror, and the metal sensor sheets are connected with the rearview mirror CPU by the bonding pad via the leading wire, thus a varying capacitive effect may be formed between a human hand and the metal sensor sheet on the PCB touchpad by touching the front frame, moreover, the rearview mirror CPU may sense variation of a capacitance value to convert it into a relevant key instruction and execute the same, further, the object of performing the touch key operation for the automobile interior rearview mirror having the anti-glare function can be realized.
