Description

Switch structure for electric rearview mirror

The present invention relates to a switch used when operating an electric rearview mirror, which is an exterior mirror of an automobile, and in particular, a selector knob for selecting left / right and an angle adjusting knob for up / down / left / right are integrally formed. By forming the size of the switch body as small as possible relates to a switch structure for an electric rearview mirror that is easy to install while improving the operation and safety.

In general, the rearview mirror of a car is classified into a fender mirror, a door mirror, and an antiglare mirror according to the installed part thereof, and the fender mirror is attached to the left and right front fenders. The rear view mirror refers to the rear view mirror, and the door mirror refers to the rear and rear view mirrors attached to the driver's and front passenger's doors.

Since the door mirror has a larger area of the mirror than the fender mirror, it is easy to check the position and distance of a subsequent vehicle, and the design is good, and the currently shipped cars are almost equipped with door mirrors. Fender mirrors and door mirrors are commonly referred to as outside mirrors.

In addition, the anti-glare mirror is a mirror installed in the interior of the vehicle, that is, the upper front of the driver's seat is made to prevent the driver's eyes from being reflected by the headlights of the subsequent car at night. In other words, the antiglare mirror is designed to convert the reflectance of the mirror by using the surface reflection and the back reflection of the prism, and to operate safely by minimizing the light reflected by the headlamp light of the vehicle following at night. It is called a mirror or room mirror.

Of these rearview mirrors installed outside the front door, that is, the outside mirror (hereinafter referred to as "the rearview mirror") is to adjust the mirror angle of the rearview mirrors according to the driver's physical condition to the top / bottom / left / right to follow the rear from behind It is easy to check the location of coming vehicles or the presence of vehicles coming from both side lanes, so it is possible to drive safely.

However, the mirror angle of the rearview mirror is manually adjusted by the lever. The rearview mirror of the driver's side door is close to the driver's seat, and the rearview mirror of the driver's side door is far from the driver's seat. Therefore, the passenger sitting in the passenger seat has to adjust several times or the driver has to open the door one by one to go out and adjust it, and then it is troublesome to sit in the driver's seat and check it.

Therefore, the electric rearview mirror that can adjust the angle of the mirrors on both sides by using the driving force of the motor to increase the convenience of operation while eliminating the inconvenience as described above, up, down, left and right is currently preferred to many drivers. There is a situation.

Such a conventional electric rearview mirror is configured such that the slide selector knob 5 for selecting the left / right rearview mirror and the push knob 4 for adjusting the up / down / left / right angle of the mirror are separated from each other as shown in FIG. 1. This moves the selector knob 5 to select the left or right rearview mirror and then selects and presses any one of the four sides of the push knob 4 to move the mirror in the selected direction to adjust the angle of the mirror.

However, since the selector knob 5 and the up / down / left / right angle adjusting push knob 4 are separated from each other by a considerable distance, the switch for operating the conventional rear view mirror is selected to operate the rear view mirror while driving the vehicle. Position selector knob (5) and the angle adjustment push knob (4) is difficult to determine the position is difficult to operate, such as bowing the head during operation.

As the left / right selection selector knob 5 and the angle adjusting push knob 4 are separated from each other as described above, the size of the switch body of the electric rearview mirror is unnecessarily enlarged, and thus is subject to many restrictions in the installation place. There is a problem.

In addition, most vehicles currently produced are configured with a folding rearview mirror so that the rearview mirror can be folded toward the body to prevent the rearview mirror from being damaged by obstacles when parking or passing through a narrow space. When trying to operate, there is a problem that it is difficult to secure a space for installing the added operation switch.

The present invention is to solve the above conventional problems, an object of the present invention is to form a switch body consisting of a selector knob for selecting left / right and a push knob for adjusting the up / down / left / right angle as small as possible By providing easy installation and positioning of selector knob and angle adjusting knob, it is possible to provide a switch structure for an electric rearview mirror that improves operability and safety.

The object of the present invention is to form a left / right selection selector knob into a ring-shaped rotary knob to select a left / right rearview mirror, and to adjust the angle of up / down / left / right in the central space of the selector knob. This is achieved by installing a push knob.

In the present invention, since the angle adjusting push knob is installed at the center of the left / right selection selector knob, the size of the switch main body can be made as small as possible, and the position of the selector knob and the angle adjusting push knob can be easily checked for operability. Since the safety can be improved, the above object can be effectively achieved.
