[0006] The force adjustment mechanism includes a mounting plate, which is fixedly installed on the left side of the connecting seat. An adjustment slot is provided on the top of the mounting plate, and a fixed base is slidably installed inside the adjustment slot. An adjustment nut is rotatably installed on the bottom of the mounting plate, and a connecting wire is provided at the bottom of the adjustment nut.

[0007] Preferably, a protrusion is fixedly installed on the bottom of the fixed base, and the protrusion is slidably installed in the adjustment slot, so that the fixed base can be limited to slide in the adjustment slot. The connecting wire is provided with wear-resistant steel wire inside, so that the connecting wire can be connected to the front wiper fixing device.

[0008] Preferably, the mounting plate and the fixed base are provided with through holes at corresponding positions of the connecting wire, and the connecting wire passes through the through holes, so that the connecting wire can slide through the fixed base and the mounting plate, thereby adjusting the compression strength of the return spring.

[0009] Preferably, the reciprocating swing mechanism includes a first connecting piece, which is fixedly installed on the top of the fixed base. A second connecting piece is fixedly installed on the top of the fixed base. Both the first and second connecting pieces have a cam-shaped structure, which facilitates the stable rotation of the swing arm shaft and the balance arm. The swing arm shaft is rotatably installed between the first and second connecting pieces, and the balance arm is rotatably installed between the first and second connecting pieces, which facilitates the rotation of the swing arm shaft and the balance arm between the first and second connecting pieces, thereby achieving the swinging water removal of the wiper blade.

[0010] Preferably, a power extension arm is fixedly installed on the front of the swing arm shaft, an upper locking block is fixedly installed at the end of the power extension arm away from the swing arm shaft, a lower locking block is fixedly installed on the top of the fixed base, and a return spring is fixedly installed between the lower locking block and the upper locking block to facilitate the wiper blade body to be tightly attached to the rearview mirror through the return spring. The bottom of the upper locking block and the top of the lower locking block are both provided with connecting grooves, and the top and bottom of the return spring are respectively fixedly installed in the grooves at the bottom of the upper locking block and the top of the lower locking block, thereby facilitating the fixed installation of the return spring between the bottom of the upper locking block and the lower locking block.

[0011] Preferably, the lower locking block has a through hole at the corresponding position of the connecting wire, the connecting wire passes through the through hole and is fixedly installed at the bottom of the upper locking block, and the connecting wire passes through the return spring, so that the connecting wire passes through the lower locking block to drive the upper locking block to press the return spring.

[0012] Preferably, the wiper blade connecting mechanism includes a mounting base, which is rotatably mounted on the end of the swing arm shaft and the balance arm away from the first connecting piece and the second connecting piece. A connecting groove is provided on the right side of the mounting base, and a connecting rod is fixedly mounted on the left side of the mounting base. A through hole is provided at the corresponding position of the mounting base and the connecting rod, and a fixed bearing is fixedly mounted inside the through hole.

[0014] Compared with the prior art, the present invention provides a linked car rearview mirror wiper, which has the following beneficial effects:

[0015] 1. This linkage-type car rearview mirror wiper is installed by connecting the connector to the fixing rod of the car rearview mirror and screwing the screw into the connecting hole to fix the connector. Then, the connecting line is connected to the fixing arm of the car front wiper. The upper locking block is pulled by the connecting line, which drives the swing arm shaft to rotate between the first connecting piece and the second connecting piece through the power extension arm. The swing arm shaft drives the balance arm to rotate synchronously through the mounting base, and the mounting base drives the wiper blade body on the mounting bracket to rotate, thus removing water from the rearview mirror. This achieves the effect of linkage between the wiper and the front windshield wiper.

[0016] 2. This linkage-type car rearview mirror wiper adjusts the oscillation force of the wiper by rotating the adjusting nut, which presses against the mounting plate and simultaneously tightens or loosens the connecting cable. This adjusts the tension of the connecting cable on the return spring, thereby adjusting the swing force of the swing arm shaft and achieving the effect of adjusting the oscillation force of the wiper.

[0017] 3. This linked car rearview mirror wiper breaks through the structure of traditional rearview mirror wipers. Its power supply and operation are simpler, eliminating the need for a separate power source. It is also simple in structure, easy to install, inexpensive, and has better performance.

[0018] 4. This linkage-type car rearview mirror wiper can be designed to work in single spring return type, double line closed type, pneumatic operation and hydraulic operation mode. Attached Figure Description
