Description

Technical Field

[0001] This utility model belongs to the technical field of protective devices, and in particular relates to a radar protection device. Background Technology

[0002] Radar is an electronic device that uses electromagnetic waves to detect targets. Radar emits electromagnetic waves to illuminate the target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the rate of change of distance, azimuth, and altitude. Since radar is mostly exposed to the outdoor environment for a long time, it is relatively easy to be damaged by external forces. Therefore, radar protection devices are needed to protect it and avoid unnecessary losses.

[0003] Chinese patent application CN221668012U discloses a radar protection device, including a base plate, a radar body disposed at the upper center of the base plate, a clamping mechanism disposed on the outer side of the bottom end of the radar body, a fixing plate fixedly installed at the front of the radar body, side plates symmetrically fixedly installed on the left and right sides of the fixing plate, and a mounting plate disposed between the rear ends of the two side plates. The bottoms of the two side plates and the mounting plate are welded and fixed to the base plate. This invention utilizes a rotating connecting rod to drive a connecting disc to rotate. A movable groove in the connecting disc compresses a movable rod, causing the movable rod to drive two connecting blocks to slide synchronously and move closer to each other, thus clamping the radar body. Rotating a bolt allows its bottom end to insert into a corresponding hole structure on the upper left of the base plate, positioning the connecting rod and ensuring stable clamping of the radar body, enabling normal operation of the radar body even in windy weather or under other external forces.

[0004] While this patent provides a sealed protection for the radar, dust accumulates on its surface during use, affecting its performance. Therefore, to improve the radar's accuracy and performance, a protective device with cleaning capabilities is needed. To address this, we provide a radar protection device to solve the aforementioned problems. Utility Model Content

[0008] The present invention is further provided that the top of the base is provided with a mounting hole, which provides a convenient way to install and fix the entire device.

[0009] The present invention is further configured such that the protective cover adopts a semi-circular design, and the surfaces of the two protective covers on opposite sides are bonded with sealing gaskets by adhesive. The semi-circular design of the protective cover is adapted to the shape of the radar body, and can form a comprehensive protective space when closed. With the sealing gaskets on the opposite side surfaces, the sealing performance of the protective cover after it is closed is significantly improved, effectively preventing external dust, moisture and other impurities from entering the protective cavity and ensuring a clean working environment for the radar body.

[0010] The present invention is further configured such that the inner wall of the connecting ring is provided with a threaded hole, and the lead screw is threadedly connected to the threaded hole, with the threaded hole and the lead screw being precisely matched to ensure that the threaded connection between the lead screw and the connecting ring is stable and reliable.

[0011] The present invention is further configured such that a mounting groove is provided at the bottom of the connecting ring, and the drive motor is mounted on the inner wall of the mounting groove, the mounting groove providing a suitable mounting space for the drive motor.

[0012] The present invention is further configured such that the sealing ring is fixedly connected to the connecting ring by bolts, which improves the connection stability between the sealing ring and the connecting ring, prevents the sealing ring from loosening or falling off during the rotation and movement of the cleaning brush, ensures the continuous and reliable sealing effect of the sealing ring, and provides a good sealing environment for vacuuming operations.

[0013] The present invention is further configured such that the bottom of the lead screw is fixedly connected to the base through a bearing, and both ends of the lead screw are stably supported, ensuring that the lead screw can rotate smoothly and stably when driven by the servo motor, reducing shaking during rotation, and ensuring the stability and accuracy of the movement of the connecting ring and the cleaning brush.

At the same time, the vacuum cleaner can promptly suck up the dust through the hollow structure of the sealing ring and the cleaning brush, avoiding secondary dust adhesion, significantly improving the accuracy and performance of the radar. Cleaning can be completed without disassembling the protective structure, which is convenient to operate and does not affect the protective effect.

[0018] 2. The protective cover of this utility model adopts a symmetrical hinge connection, which, together with the drive of the electric push rod, ensures a smooth opening and closing process. After closing, the sealing gasket achieves a sealed protection, effectively isolating dust, moisture and other impurities in the external environment. The limiting rod in the cleaning component guides and limits the connecting ring, ensuring the precise movement trajectory of the cleaning brush and avoiding deviation that could damage the radar. The sealing ring ensures the airtightness of the dust collection process and improves dust collection efficiency. Attached Figure Description

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1-5 This utility model is a radar protection device, including a protection component 1. A cleaning component 2 is fixedly connected to the inner cavity of the protection component 1. The protection component 1 includes a base 11, and a radar body 12 is fixedly connected to the top of the base 11.

The mounting bracket 211 is vertical. The plate and servo motor 21 are fixedly mounted on the mounting bracket 211 by bolts. The output shaft of the servo motor 21 is fixedly connected to the lead screw 22. The surface of the lead screw 22 is threadedly connected to the connecting ring 23. The inner wall of the connecting ring 23 is movably connected to the cleaning brush 24 through the bearing. The bottom of the surface of the cleaning brush 24 is fixedly connected to the gear ring 25. The surface of the gear ring 25 is meshed with the gear 26. The top of the gear 26 is fixedly connected to the drive motor 27. The drive motor 27 is fixedly connected to the inner wall of the connecting ring 23. The top of the surface of the cleaning brush 24 is movably connected to the sealing ring 28 through the bearing. The surface of the sealing ring 28 is connected to the vacuum cleaner 29 through the hose.

[0028] Specifically: the installation position of the radar body 12 corresponds to the central area of ​​the base 11. The protective cover 13 is movably connected to the edge of the top two sides of the base 11 through hinges. When the electric push rod 14 extends and retracts, it can smoothly drive the protective cover 13 to open and close. The inner ring of the sealing ring 28 is tightly fitted with the surface of the cleaning brush 24. The outer surface of the sealing ring 28 is connected to the vacuum cleaner 29 through a flexible hose to ensure the sealing of the vacuuming channel.

[0029] The top of the base 11 has mounting holes, which provide a convenient way to install and fix the entire device.

[0030] The protective cover 13 adopts a semi-circular design, and the surfaces of the two protective covers 13 on opposite sides are bonded with sealing gaskets by adhesive. The semi-circular design of the protective cover 13 is adapted to the shape of the radar body 12. When closed, it can form a comprehensive protective space. With the sealing gaskets on the opposite side surfaces, the sealing performance of the protective cover 13 after closing is significantly improved, effectively preventing external dust, moisture and other impurities from entering the protective cavity and ensuring a clean working environment for the radar body 12.

[0031] The inner wall of the connecting ring 23 is provided with a threaded hole, and the lead screw 22 is threadedly connected to the threaded hole. The threaded hole and the lead screw 22 are precisely matched to ensure that the threaded connection between the lead screw 22 and the connecting ring 23 is stable and reliable.

[0032] The bottom of the connecting ring 23 is provided with a mounting groove, and the drive motor 27 is mounted on the inner wall of the mounting groove. The mounting groove provides a suitable mounting space for the drive motor 27.

[0033] The sealing ring 28 is fixedly connected to the connecting ring 23 by bolts, which improves the connection stability between the sealing ring 28 and the connecting ring 23, prevents the sealing ring 28 from loosening or falling off during the rotation and movement of the cleaning brush 24, ensures the continuous and reliable sealing effect of the sealing ring 28, and provides a good sealing environment for vacuuming operations.

[0034] The bottom of the lead screw 22 is fixedly connected to the base 11 via a bearing. Both ends of the lead screw 22 are stably supported, ensuring that the lead screw 22 can rotate smoothly and stably when driven by the servo motor 21, reducing shaking during rotation, and ensuring the stability and accuracy of the movement of the connecting ring 23 and the cleaning brush 24.

[0035] The cleaning brush 24 has a hollow design and a dust suction hole on its inner wall. The cleaning brush 24, together with the dust suction hole on the inner wall, can form a complete dust suction channel with the vacuum cleaner 29.

[0036] Limiting rods 210 are slidably connected to both ends of the inner cavity of the connecting ring 23. The bottom of the limiting rods 210 is fixedly connected to the base 11. The limiting rods 210 can restrict the movement trajectory of the connecting ring 23, prevent the connecting ring 23 from rotating or shifting with the lead screw 22, and ensure that the connecting ring 23 always moves in the vertical direction, so that the cleaning brush 24 can accurately fit the surface of the radar body 12 for cleaning, ensuring the accuracy and reliability of the cleaning operation.

[0037] The working principle of this utility model is as follows: In the non-working state, the electric push rod 14 drives the protective cover 13 to rotate inward and close via the hinge. The two protective covers 13 cooperate to form a sealed protective space, protecting the radar body 12 on the base 11 and preventing damage from external forces and the intrusion of impurities. When the radar needs to be used or cleaning operations are required, the electric push rod 14 drives the protective cover 13 to rotate outward and open. During cleaning operations, the protective cover 13 remains open, and the servo motor 21, drive motor 27, and vacuum cleaner 29 in the cleaning assembly 2 are started. The servo motor 21 drives the lead screw 22 to rotate. The connecting ring 23 is threadedly connected to the lead screw 22 and guided by the limiting rod 210. The connecting ring 23 moves vertically downward along the lead screw 22. At the same time, the drive motor 27 drives the gear 26 to rotate. The gear 26 meshes with the gear ring 25 at the bottom of the cleaning brush 24, driving the cleaning brush 24 to rotate. The rotating cleaning brush 24 adheres to the surface of the radar body 12 for cleaning. The vacuum cleaner 29 is connected to the sealing ring 28 through the hose. The dust generated by the rotation of the cleaning brush 24 enters the hollow cavity through the dust suction hole on its inner wall and is then sucked away by the vacuum cleaner 29, realizing the synchronous collection of dust. After cleaning is completed, the radar can enter the working state.

[0038] Finally, it should be noted that this application applies to radars with a columnar shape, such as the Velodyne radar and the Quanergy 3D M8 lidar.
