detailed description

The present invention will now be described in further detail in a specific embodiment, but it should be noted that the scope of the invention is not limited thereto.

In the following description, the front, rear, left, right, up, and down directions are defined by the orientation in which the rear view mirror of the automobile is mounted in the automobile.

1 is an exploded perspective view of an interior rear view mirror of the present invention, and FIG. 5 is a schematic structural view of the interior rear view mirror of the present invention. As shown in FIGS. 1 and 5, the interior rear view mirror according to the present invention includes a front cover 1, a rear cover 2, a mirror glass 3 mounted between the front cover and the rear cover, a display screen 4, and a PCB board. 5 and the rear view mirror bracket 6.

2 is a schematic enlarged structural view of a button of a rear view mirror of an automobile according to the present invention, FIG. 3 is a schematic view of a button hole in a front cover of a rear view mirror of the automobile of the present invention, and FIG. 4 is a button inserted into a front cover of the button; Schematic diagram after the hole. As shown in FIG. 1 to FIG. 5, the front cover 1 is provided with a button hole 7, and the button hole 7 is provided with a button 8. The button 8 includes a key cap 81, a button PCB 82, and an electronic button disposed on the button PCB 82. 83. The keycap 81 is provided with a first limiting bone 811. The button hole 7 is provided with a limiting slot 71 matched with the first limiting bone 811, and the limiting slot is used for accommodating the first limiting position. Bone 811. The first limiting bone 811 has a shape in which the central concave ends protrude toward the limiting groove 71. The engagement of the first limiting bone 811 of the key cap 81 with the limiting slot 71 in the button hole 7 ensures the lower limit of the lower portion of the button 8 in the left-right direction. In addition, the limiting slot 71 can also ensure the limit of the button 8 in the downward direction.

Further, two outer semi-circular shafts 812 are disposed in the outer edge of the key cap 81, and two semi-circular grooves 72 are disposed in the button hole 7 for placing two semicircular rotating shafts 812. The two semicircular shafts 812 are respectively disposed on two sides of the first limiting bone 811, and the two semicircular grooves 72 are respectively disposed in the limiting slots in the button hole 7. On both sides of the 71. The semicircular shaft 812 of the button 8 is rotatable within the semicircular groove 72 of the button hole 7, i.e., the button 8 is moved centering on the semicircular shaft 812.

Further, a buckle 813 is disposed on each of the left and right sides of the key cap 81, and two limit seats 73 corresponding to the buckle 813 are disposed in the button hole 7. The end of the buckle 813 is provided with a protruding buckle, and the buckle abuts the limiting seat. The engagement of the buckle 813 of the key cap 81 with the limiting seat 73 in the button hole 7 realizes the limitation of the upper portion of the button 8 in the left-right direction, and the buckle on the buckle 813 can ensure that the button 8 does not fall out. That is, the limit in the forward direction.

Further, a second limiting bone 814 is disposed on a side of the keyhole 81 opposite to the first limiting bone 811, and a side of the button hole 7 opposite to the limiting slot 71 is provided with a second limiting position. The bone 814 performs a third limited bone 74. The second limiting bone 814 has a T-shape. When the button 8 is disposed in the button hole 7, the third limiting bone 74 is disposed outside the second limiting bone 814. When the button 8 moves in the button hole 7, it is restricted by the third limiting bone 74 in the button hole 7 in the upward direction.

Further, the second limiting bone 814 is provided with a button generating portion 815, and the button generating portion 815 is in contact with the electronic button 83 to achieve a rear limit. The button force transmitting portion 815 is a vertical portion of the second limiting bone of the T-shape.

Therefore, in the in-vehicle rearview mirror of the present invention, the button 8 is provided with a limit of six directions of left and right, up and down, and front and rear, which will be specifically described below with reference to FIGS. 6 to 13:

1, the left and right direction of the limit

As shown in FIG. 4 and FIG. 11 , the limit of the left and right direction of the button 8 of the present invention is implemented from two aspects. First, when the button 8 is inserted into the button hole 7 of the front cover 1 , the button 8 is provided. The first limiting bone 811, the first limiting bone 811 is just inside the limiting slot 71 in the button hole 7, thereby ensuring The lower part of the button 8 is limited in the left and right direction. Second, since the button 8 is provided with the buckle 813 in the left and right direction, the buckle 813 corresponds to the limit seat 73 in the button hole 7, thereby realizing the upper part of the button 8 in the left and right direction. Limit.

2, the front and rear direction limit

As shown in FIGS. 7, 9, and 11, the outer edge portion of the button 8 of the present invention is provided with a semicircular shaft 812. When the button 8 is loaded into the front cover 1, the semicircular shaft 812 of the button 8 is caught in the button hole 7 of the front cover. In the semicircular groove 72, a top and bottom movement track of the button 8 is realized by using the semicircular rotation shaft 812 as a center and the electronic button 83 as a radius; the left and right sides of the button 8 are provided with two long buckles 813, and The two buckles 813 are disconnected from the upper limit bone 814 of the upper portion of the button 8, and the button 8 is formed by one-time injection molding of polymer engineering plastic, so that the buckle 813 is guaranteed to have a certain degree from two aspects. Rigid, and has the unique elasticity of the plastic. Since the two buckles 813 are fastened to the limiting seat 73 in the button hole 7 of the front cover, the button can be prevented from falling out, that is, the forward limit function; The button force transmitting portion 815 on the 8 is in contact with the electronic button 83, thereby functioning as a rear limit.

3, the limit of the up and down direction

As shown in FIG. 7 , the upper and lower limit of the present invention is mainly implemented by the following three aspects: 1. Since the button hole 7 of the front cover is provided with the limiting slot 71, when the button 8 is inserted into the button hole 7, the The first limiting bone 811 is also inserted into the limiting slot 71. In addition to ensuring the left and right limits of the button 8, the limiting slot 71 can also ensure the limit of the button 8 in the downward direction, because the rubber wall of the limiting slot 71 blocks The first limiting bone 811 of the button 8 is provided. Second, since the semicircular groove 72 is provided in the button hole 7 of the front cover, when the semicircular rotating shaft 812 of the button 8 is rotated in the semicircular groove 72, the button 8 can be ensured to be a semicircular rotating shaft 812. For the center of the ball to move; three, when the button 8 moves within the button hole 7, since the button 8 and the button hole 7 have When the gap is fixed, the second limiting bone 814 of the button 8 is restricted by the third limiting bone 74 in the button hole 7 of the front cover in the upward direction during the movement.

In the interior rearview mirror of the present invention, the button works by cooperating with the front cover and the button PCB and the electronic buttons on the PCB, and the front, the rear, the left, the right, the upper and the lower are arranged inside the button. The limit position is adjusted by the rotating shaft structure, and is especially suitable for the automobile interior rearview mirror with curved surface shape, and has the advantages of simple structure, reliability, stability, convenient operation and cost saving.

While the embodiments of the present invention have been described with reference to the embodiments of the present invention, various modifications and changes may be made without departing from the scope of the appended claims. It should be within the scope of the invention.
