[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 and Figure 2As shown, an angle-adjustable blind spot sensor includes a connecting frame 1, a drive assembly 2, a servo motor 201, a lead screw 202, an upper gear 203, a lower gear 204, a camera 3, a millimeter-wave radar 4, a fixing plate 5, a cleaning plate 6, a side frame 7, an auxiliary assembly 8, a connecting shaft 801, a side gear 802, and an electric push rod 803. The connecting frame 1 houses the drive assembly 2 for angle adjustment, which includes the servo motor 201, lead screw 202, upper gear 203, and lower gear 204. A fixing plate 5 is fixedly mounted on one side of the connecting frame 1, and a cleaning plate 6 is engaged within the fixing plate 5. This engagement design facilitates replacement of the cleaning plate 6 after prolonged use. A camera 3 is mounted on one side of the outer surface of the cleaning plate 6. The height of the cleaning plate 6 is less than the height of the connecting frame 1. A lead screw 202 is mounted on the output end of the servo motor 201, and an upper gear is threaded onto the outer surface of the lead screw 202. 203. The upper gear 203 and the lower gear 204 have the same diameter and are both located inside the connecting frame 1. The lower gear 204 is installed at the bottom of the upper gear 203. A camera 3 is installed between the upper gear 203 and the lower gear 204. A millimeter-wave radar 4 is installed above the camera 3. The camera 3 and the millimeter-wave radar 4 monitor blind spots that cannot be covered in real time. The servo motor 201 drives the lead screw 202 to rotate. The rotation of the lead screw 202 drives the upper gear 203 and the lower gear 204 that are threaded to it. The lead screw 202 rotates up and down about the outer surface of the lead screw 202. The angle and height can be adjusted accordingly when the position of the camera 3 and the millimeter-wave radar 4 are adjusted. When the angle and height of the camera 3 and the millimeter-wave radar 4 are adjusted, the camera 3 can contact the cleaning brush on one side of the cleaning plate 6. The camera 3 can be cleaned during the adjustment process so that it can be used again.

[0022] like Figure 1 and Figure 3As shown in the figure, a side frame 7 is provided on one outer side of the connection frame 1, and the inside of the side frame 7 is in a "匚" - shaped structure. An auxiliary component 8 for assisting in height and angle adjustment and conversion is provided inside the side frame 7. The auxiliary component 8 includes a connecting shaft 801, a side gear 802, and an electric push rod 803. A side gear 802 is provided on the outer side of the connecting shaft 801, and an electric push rod 803 is installed at the bottom of the connecting shaft 801. The side gear 802 is meshed with one side of the outer surfaces of the upper gear 203 and the lower gear 204, and the length of the side gear 802 is greater than that of the upper gear 203 and the lower gear 204. One end of the electric push rod 803 is installed on the side frame 7, and the connection frame 1 and the side frame 7 are interconnected. Through the design of the electric push rod 803, the position of the connecting shaft 801 and the side gear 802 can be driven to move. By moving the connecting shaft 801 and the side gear 802, they can be meshed with one side of the outer surfaces of the upper gear 203 and the lower gear 204, so as to limit the upper gear 203 and the lower gear 204. It can separate the control of the angles and heights of the camera 3 and the millimeter - wave radar 4. Benefiting from the design of the connecting shaft 801 and the side gear 802, when the driving screw rod 202 rotates to drive the upper gear 203 and the lower gear 204 to rotate up or down, vertical direction limiting can be carried out to ensure that the upper gear 203 and the lower gear 204 can stably move up or down, facilitating the independent height adjustment of the camera 3 and the millimeter - wave radar 4 in the upper gear 203 and the lower gear 204, and facilitating the angle and height coordination and non - coordination adjustment according to the needs of the user.

[0023] In summary, for this angle - adjustable blind - area sensor, first, according to Figures 1-3The structure shown allows for real-time monitoring of blind spots by camera 3 and millimeter-wave radar 4. The servo motor 201 drives the lead screw 202 to rotate, which in turn drives the threaded upper gear 203 and lower gear 204, allowing for rotational up-and-down movement of the lead screw 202 relative to its outer surface. This enables the angle and height of camera 3 and millimeter-wave radar 4 to be adjusted accordingly during position changes. Furthermore, during these adjustments, camera 3 can contact the cleaning brush on one side of the cleaning plate 6, cleaning it during the adjustment process for reuse. The electric push rod 803 drives the connecting... The position of shaft 801 and side gear 802 can be moved, and by moving the connecting shaft 801 and side gear 802, they can mesh on one side of the outer surface of upper gear 203 and lower gear 204, which can limit the upper gear 203 and lower gear 204. It can independently control the angle and height of camera 3 and millimeter-wave radar 4. The design of connecting shaft 801 and side gear 802 is beneficial to the vertical limit when the drive screw 202 rotates to drive the upper gear 203 and lower gear 204 to rotate up or down, ensuring that the upper gear 203 and lower gear 204 can move stably up or down, which facilitates the independent height adjustment of camera 3 and millimeter-wave radar 4 in upper gear 203 and lower gear 204.
