The frame of the rearview mirror bracket can reflect the situation behind, to the side and below the car, so that the driver can indirectly see the situation in these positions. It plays the role of a "second eye" and expands the driver's field of vision. In the production process of the current rearview mirror bracket, the shell and frame of the rearview mirror bracket need to be pressed and connected to produce a good quality rearview mirror bracket for safe installation on the car.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. The frame of the automobile rearview mirror is clamped and fixed by using multiple clamping plates, so that the movable end of the electric push rod drives the pressing seat to move downward in the vertical direction, and the pressing seat drives multiple side plates and multiple first wedge blocks to move downward synchronously, so that the second wedge block slides a certain distance, and the second wedge block drives the fixing plate to move synchronously through the extension column, so that the multiple fixing plates move toward the outer shell of the automobile rearview mirror bracket, and the multiple fixing plates automatically clamp the outer shell of the automobile rearview mirror bracket;

[0021] 2. The press-fit seat continues to move downward for a distance, and the multiple vertical plates, clamping plates and lower pressing plates arranged on the bottom wall of the press-fit seat will drive the frame of the automobile rearview mirror to enter the shell of the automobile rearview mirror bracket to complete the press-fit connection. Subsequently, under the action of the third wedge block and the wedge hole, the driven plate will drive the vertical plate to slide a distance away from the automobile rearview mirror bracket after the press-fit connection, so that the lower pressing plate is out of contact with the automobile rearview mirror bracket. At this time, the press-fit seat continues to slide downward for a distance, so that the detection suction cup and the lens of the frame of the automobile rearview mirror bracket after the press-fit connection are in contact with each other to generate suction;

[0022] 3. Then, the movable end of the electric push rod moves in the opposite direction, and the detection suction cup will drive the lens of the frame part of the rearview mirror bracket to move upward synchronously. If the pressing and clamping of the outer shell part and the frame part in the rearview mirror bracket are not firm, the outer shell part and the frame part in the rearview mirror bracket will separate again, that is, the pressing and assembly of the rearview mirror bracket is unqualified;

[0023] 4. If the press-fit connection of the automobile rearview mirror bracket is firm, the mirror frame and the shell will not be separated, and the detection suction cup will drive the detection block to slide for a certain distance in the vertical direction inside the empty groove. By setting structures such as circular grooves, cams and sliding plugs, the cam periodically pushes the sliding plug to slide back and forth on the inner wall of the second cavity, and then the sliding plug intermittently squeezes the gas into the corresponding injection hole for ejection. The high-speed airflow ejected from the injection hole can blow away impurities such as dust adhering to the automobile rearview mirror bracket after the press-fit connection, thereby improving the cleaning ability of the surface of the automobile rearview mirror bracket after the press-fit connection.

When the first wedge block 6 pushes the second wedge block 7 to slide to the end of the stroke, the tension spring 43 is squeezed, and the pressing seat 4 can continue to move downward for a distance.

[0043] In the present invention, the user places the outer shell of the automobile rearview mirror bracket in the placement groove 19, and the inner contour of the placement groove 19 is consistent with the bottom contour of the outer shell of the automobile rearview mirror bracket, so that the automobile rearview mirror bracket can be stably placed.

[0044] The plurality of vertical plates 14 are pulled so that each vertical plate 14 drives the corresponding slider 12 to squeeze the clamping spring 13 and shrink a certain distance, so that the user can place the mirror frame part needed to be placed near the plurality of clamping plates 16.

Since the detection suction cup 22 and the lens of the frame part of the automobile rearview mirror bracket after the pressing and clamping are against each other and sucked, the detection suction cup 22 will drive the lens of the frame part of the automobile rearview mirror bracket to move upward synchronously. If the pressing and clamping of the automobile rearview mirror bracket is firm, the frame part and the shell part will not be separated, and the detection suction cup 22 will drive the detection block 21 to slide in the vertical direction for a distance inside the empty groove 20, then the spiral groove 24 provided in the circular groove 23 on the top wall of the detection block 21 will drive the guide rod 26 to slide along the groove track of the spiral groove 24, and then the guide rod 26 will drive the first rod 25 fixedly connected thereto to rotate, then the first rod 2 5 drives the first gear 28 fixedly connected to its side wall to rotate, the first gear 28 drives the multiple second gears 29 meshing with it to rotate, the second gears 29 drive the second rod 30 to rotate, and after the second rod 30 rotates, it drives the cam 32 fixedly connected to its side wall to rotate synchronously, the cam 32 periodically pushes the sliding plug 33 to slide back and forth in a sealed manner on the inner wall of the second cavity 31, and then the sliding plug 33 will draw the external gas into the second cavity 31 through the first one-way tube 35, and then squeeze it into the corresponding injection hole 37 through the second one-way tube 36 to be sprayed out, the high-speed airflow sprayed from the injection hole 37 can blow away the dust and other impurities adhered to the automobile rearview mirror bracket after the press-fitting, so as to improve the cleaning ability of the surface of the automobile rearview mirror bracket after the press-fitting.

[0047] When the pressing seat 4 continues to move upward, the sliding distance between the detection block 21 and the empty slot 20 is limited. When the detection block 21 slides to the end of the stroke, the detection suction cup 22 will be disengaged from the lens of the frame part of the automobile rearview mirror bracket after the pressing and clamping. Then, under the action of the reset spring 41, the detection block 21 will slide and reset in the opposite direction to be used for the next detection.
