[0036] Please refer to Figures 2 to 6, this embodiment provides an expandable driving vision device, which includes a mounting plate 1, an adjusting mechanism 3 and a rearview mirror 2. The mounting plate 1 is used for detachably setting on the A-pillar 4. An adjusting mechanism 3 is provided on the mounting plate 1, and a rearview mirror 2 is provided on the adjusting mechanism 3. The front of the rearview mirror 2 is a mirror surface, and the mirror surface faces the inside of the vehicle. The adjusting mechanism 3 is used for rotating the rearview mirror 2 left and / or right and up and down.

[0037] The A-pillar 4 is one of the two vertical columns located at the front of the vehicle, connecting the front windshield and the roof. In most vehicle designs, the A-pillar 4 is located in front of the driver's and co-driver's seats and is a key structural component that supports the vehicle roof and fixes the front windshield. The A-pillar 4 not only provides the structural strength of the vehicle body to help protect passengers in a collision accident but also plays a role in fixing the car door. The mounting plate 1 is designed to be detachable so that it can be firmly installed on the A-pillar 4 of the vehicle without damaging the structural stability of the vehicle's A-pillar 4.

[0038] The rearview mirror 2 itself has a mirror surface on the side facing the inside of the vehicle, which is used to capture and reflect the vision in front of the co-driver's side. The adjusting mechanism 3 allows the rearview mirror 2 to rotate in the horizontal direction (left and right) and / or the vertical direction (up and down), ensuring that the driver can obtain a better vision effect in the driver's seat.

[0039] When the vehicle is in a driving state, if there is another vehicle blocking the vision on the co-driver's side ahead, the driver can adjust the adjusting mechanism 3 manually or electrically to rotate the rearview mirror 2 to an appropriate angle. At this time, the vision originally blocked by the A-pillar 4 will enter the driver's line of sight through the mirror reflection of the rearview mirror 2, and the driver can view the front vision on the co-driver's side from the rearview mirror 2, greatly reducing the vision blind area on the co-driver's side and improving driving safety.

[0040] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , in this embodiment, the adjusting mechanism 3 includes a first motor 31, a first connecting plate 32, a second motor 33, a second connecting plate 34 and a controller 35. The first motor 31 is provided on the mounting plate 1. A first connecting plate 32 is provided on the output shaft 311 of the first motor 31. The output shaft 311 of the first motor 31 extends left and right. A second motor 33 is provided on the first connecting plate 32. A second connecting plate 34 is provided on the output shaft 331 of the second motor 33. The output shaft 331 of the second motor 33 extends up and down. The back of the rearview mirror 2 is provided on the second connecting plate 34. Among them, the rearview mirror 2 rotates up and down following the up and down rotation of the output shaft 311 of the first motor 31 and rotates left and right following the left and right rotation of the output shaft 331 of the second motor 33. The first motor 31 and the second motor 33 are respectively connected to the controller 35, and the controller 35 is connected to an operation module.

[0041] When the driver issues an instruction to adjust the angle of the rearview mirror 2 through the operation module, the signal will be transmitted to the controller 35. The controller 35 controls the operation of the first motor 31 and the second motor 33 according to the received instruction to precisely adjust the position of the rearview mirror 2. Specifically, the first motor 31 is responsible for the up and down rotation of the rearview mirror 2, while the second motor 33 controls the left and right rotation of the rearview mirror 2, ensuring that the rearview mirror 2 can flexibly adapt to various driving scenarios. The driver can conveniently and quickly adjust the angle of the rearview mirror 2, especially during driving, which greatly improves driving safety and comfort.

[0042] In this embodiment, the operation module is designed near the driver's seat, such as on the center console, steering wheel, central armrest, etc., so that the driver can easily reach the operation module without significantly changing their posture or line of sight.

[0043] In this embodiment, the operation module includes multiple buttons. These buttons can be physical buttons or touch-sensitive virtual buttons, integrated on the center console, steering wheel, or other positions easily accessible to the driver. The multiple buttons respectively correspond to different control functions. For example: Up / Down buttons: Control the first motor 31 to make the rearview mirror 2 rotate up and down in the vertical direction; Left / Right buttons: Control the second motor 33 to make the rearview mirror 2 rotate left and right in the horizontal direction; Reset button: Adjust the rearview mirror 2 back to the initial set position.

[0044] Please refer to Figure 2 、 Figure 3 and Figure 4 In this embodiment, the first motor 31 and the second motor 33 are electrically driven motors - electric motors. As the power source, the working principle of the electrically driven motor is based on the electromagnetic effect, that is, the interaction between the magnetic field generated by the current passing through the coil and the permanent magnet to drive the rotation of the motor shaft. When the driver issues an instruction through the operation module, the signal is transmitted to the controller 35, and the controller 35 then converts the electrical signal into a motion instruction for the motor, controlling the rotation direction and speed of the motor by adjusting the direction and magnitude of the current, thereby precisely adjusting the angle of the rearview mirror 2.

[0045] In some embodiments, only one motor is required to achieve either the up-and-down rotation or the left-and-right rotation of the rearview mirror 2. The adjusting mechanism 3 includes a third motor, which is provided on the mounting plate 1. A third connecting plate is provided on the output shaft of the third motor, and the back surface of the rearview mirror 2 is provided on the third connecting plate. Among them, the output shaft of the third connecting plate extends vertically or horizontally. This solution is applicable to scenarios where only the field of view needs to be expanded in a certain direction, or application scenarios with higher requirements for cost and complexity, and the use of only one motor reduces the cost. The visual blind area caused by the A-pillar 4 is mainly horizontal. Preferably, the third motor drives the rearview mirror 2 to rotate left and right, which can directly cover and compensate for the lack of the horizontal field of view, and more effectively solve the visual blind area problem caused by the occlusion of the A-pillar 4.

[0046] This embodiment also provides an automobile, including a vehicle body, the vehicle body has an A-pillar 4, and further includes the expandable driving vision device described in any one of the above embodiments, and the structure is as Figures 2 to 6 shown. The mounting plate 1 of the expandable driving vision device is detachably provided on the A-pillar 4, and the structure is as Figure 6 shown.

[0047] Please refer to Figure 6 , in this embodiment, the vehicle body has two A-pillars 4 on the left and right, and the mounting plate 1, the adjusting mechanism 3 and the rearview mirror 2 are provided on the A-pillar 4 located on the co-driver's seat. The driver's seat refers to the position where the driver sits, usually on the left side (in a left-hand drive vehicle) or the right side (in a right-hand drive vehicle) of the vehicle, and the co-driver's seat is located next to the driver's seat, usually on the right side (in a left-hand drive vehicle) or the left side (in a right-hand drive vehicle) of the vehicle. Preferably, the mounting plate 1, the adjusting mechanism 3 and the rearview mirror 2 are provided on each A-pillar 4, and the driver in the driver's seat or the passenger in the co-driver's seat can control the angle of the rearview mirror 2 through an operation module (such as a button or a touch screen) to reduce the visual blind area caused by the A-pillar 4.

[0048] In this embodiment, the mounting plate 1 is provided on the A-pillar 4 by bolts or buckles. The bolt fixing method usually includes pre-drilling holes in the A-pillar 4, and then fastening the mounting plate 1 on the A-pillar 4 by screwing in bolts and nuts or using expansion screws. The advantage of this fixing method is high stability, which can withstand large external forces and ensure that the rearview mirror 2 can still maintain its position unchanged during high-speed driving or under harsh road conditions. The buckle fixing method uses buckles made of elastic materials to clamp the mounting plate 1 at a predetermined position on the A-pillar 4 through pressure or elastic deformation. This fixing method is more convenient for installation and disassembly, without tools, and is suitable for scenarios where the device needs to be adjusted or replaced frequently. In some embodiments, the mounting plate 1 can also be fixed by a pull strap or a tie strap.

[0049] Please refer to Figure 6, in this embodiment, the rearview mirror 2 is located in the central direction of the A-pillar 4 towards the vehicle body, and the mirror surface of the rearview mirror 2 faces the interior of the vehicle, rather than directly towards the outside or the front. This design ensures that the rearview mirror 2 can capture the front view on the co-pilot side that was originally blocked by the A-pillar 4 and reflect the image to the driver, thereby reducing the blind spot.

[0050] The present application has the following beneficial effects:

[0051] The newly designed A-pillar is equipped with a rearview mirror that widens the field of view. The rearview mirror is installed on the A-pillar and has a rotation function at a certain angle. The driver can input an adjustment signal to the controller through an adjustment button. The adjustment signal is processed by the controller and output to the adjustment mechanism of the rearview mirror, thereby realizing the angular rotation of the rearview mirror in all directions.

[0052] The structure is simple and can be retrofitted on the existing A-pillar, and it is applicable to both left-hand drive and right-hand drive vehicles, making the application scenario more extensive.

[0053] Advantages such as reducing the field of view blind spot and increasing driving safety.

[0054] It should be noted that although the above embodiments have been described in this article, the patent protection scope of the present utility model is not limited thereby. Therefore, based on the innovative concept of the present utility model, any changes and modifications made to the embodiments described in this article, or equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, and directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present utility model.
