[0071] The sliding bar 411 and the mounting plate 6 are hinged via the first hemispherical support 414 and the first ball head 415 , so that the sliding of the sliding bar 411 can push the mounting plate 6 and the second mirror surface 3 to deflect.

[0072] Furthermore, in the present device, the first ball head 415 is rotatably embedded in the first hemispherical support 414 to form a ball head hinge, which is a conventional setting well known to those skilled in the art and will not be described in detail here.

The racks 4121 are arranged one by one with the sliding bars 411, and the two racks 4121 are respectively connected to the opposite sides of the two sliding bars 411. The rotating shaft 4122 is rotatably connected to the opening box 5. The first transmission gear 4123 is fixedly sleeved on the rotating shaft 4122 and is connected to the two racks 4121. 21 are meshed with each other, a speed gear 4124 is fixedly sleeved on the rotating shaft 4122, a second transmission gear 4125 is meshed with the speed gear 4124, a fixed end of a driving motor 4126 is connected to the bottom inner wall of the opening box 5, and an output shaft is connected to the second transmission gear 4125, for driving the first transmission gear 4123 to mesh with the two racks 4121 at the same time, and making the two sliding bars 411 slide in opposite directions, so that the mounting plate 6 and the second mirror surface 3 rotate around the first direction as the axis.

[0075] Furthermore, the rack 4121, rotating shaft 4122, first transmission gear 4123, speed gear 4124, second transmission gear 4125 and drive motor 4126 in the present device are all common and easily purchased gear transmission structures on the market, which are conventional settings well known to those skilled in the art and will not be elaborated here.

[0077] The limiting plate 416 is used to guide the sliding of the sliding bar 411 relative to the open box 5 .

[0078] like Figures 2 to 4As shown, the mounting plate 6 is also provided with a second sliding groove, the second adjusting member 42 includes a second sliding block 421, a second hemispherical support 422, a second ball head 423 and a linear driving portion 424, the second sliding block 421 is slidably embedded in the second sliding groove, the second hemispherical support 422 is connected to the second sliding block, the second ball head 423 is rotatably embedded in the second hemispherical support 422, and the linear driving portion 424 has a fixed end and an extended end, the fixed end of the linear driving portion 424 is connected to the bottom inner wall of the opening box 5, and the extended end is connected to the second ball head 423, which is used to drive the second ball head 423 to slide along the third direction, so as to drive the mounting plate 6 and the second mirror 3 to rotate around the second direction as the axis.

[0079] The second ball head 423 is hinged to the mounting plate 6 by the driving of the linear driving part 424 , and the mounting plate 6 and the second mirror surface 3 are rotated around the second direction as the axis, thereby realizing the up and down deflection of the second mirror surface 3 relative to the first mirror surface 2 .

[0080] Furthermore, the linear drive unit 424 here is a common and easily purchased air cylinder, hydraulic cylinder or push rod motor on the market, which is a conventional setting known to those skilled in the art and will not be described in detail.

[0081] As another implementation method, Figure 2 As shown, the second adjustment member 42 also includes two L-shaped plates 425, a guide block 426, a baffle 427 and a distance sensor 428. The two L-shaped plates 425 are arranged at intervals along the third direction, and the two L-shaped plates 425 are surrounded to form a guide groove. The linear drive part 424 is built into the guide groove. The guide block 426 is fixedly mounted on the extended end of the linear drive part 424 and is slidably connected to the guide groove.

Here, the control component 7 is a PLC controller that is common and easy to purchase on the market, and will not be described in detail here.

[0086] Furthermore, the control component 7 of the device can obtain the turning angle and uphill and downhill angle of the driving car, and perform feedback adjustment on the extension end of the drive motor 4126 and the linear drive part 424, so as to realize horizontal deflection adjustment and vertical deflection adjustment of the second mirror 3, which can expand the driver's rear view field of view without affecting the normal use of the first mirror 2, thereby increasing the safety of the driving process.

Compared with the prior art, by movably arranging the second mirror 3 on the first mirror 2, and the second mirror 3 is hinged to the housing 1 through the adjustment component 4, the second mirror 3 can be deflected relative to the first mirror 2 and form an angle. After the angle is formed, the second mirror 3 can compensate or extend the blind area of ​​the field of view on the first mirror 2, and can obtain a field of view that a conventional rearview mirror cannot obtain when turning.

[0088] When in use, the control component 7 first obtains the turning angle and the uphill and downhill angle of the driving car, and performs feedback adjustment on the extension end of the driving motor 4126 and the linear driving part 424. Then the control component 7 controls the driving motor 4126 or the linear driving part 424 to move respectively. The driving motor 4126 drives the first transmission gear 4123 to mesh with the two racks 4121, and drives the two sliding bars 411 to slide relative to the limit plate 416. The sliding sliding bar 411 can make the first ball head 415 relative to the first hemispherical support The seat 414 rotates and eventually pushes the second mirror 3 and the mounting plate 6 to deflect left and right relative to the first mirror 2. The extended end of the linear drive part 424 can drive the first ball head 415 to slide close to or away from the fixed end of the linear drive part 424. After sliding, the second ball head 423 rotates relative to the second hemispherical support 422 and eventually pushes the second mirror 3 and the mounting plate 6 to deflect up and down relative to the first mirror 2, thereby expanding the driver's rear view field of view without affecting the normal use of the first mirror 2, thereby increasing the safety of the driving process.

[0089] The device, through the above structure, can solve the technical problem in the prior art that the blind spot at the angle between the extension line parallel to the vehicle and the lane when the vehicle turns cannot be viewed through a conventional rearview mirror, resulting in a limited field of view provided by the rearview mirror.

[0090] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
