Description

Technical Field

[0001] This invention belongs to the field of electromechanical technology and relates to an automatic radar leveling device. Background Technology

[0002] Radar requires a level surface to ensure accuracy during reconnaissance. However, since radar is mounted on a reconnaissance vehicle, which may be on any inclined surface during reconnaissance, the vehicle cannot provide a level surface for the radar, thus failing to achieve the desired accuracy. Figure 1 The effect shown. Summary of the Invention

[0003] (I) Purpose of the Invention

[0004] The purpose of this invention is to provide an automatic radar leveling device that enables the radar mounting surface to be on a horizontal plane when the reconnaissance vehicle is located on any inclined surface.

[0005] (II) Technical Solution

[0006] To address the aforementioned technical problems, this invention provides an automatic radar leveling device. Based on the principle that two straight lines determine a plane, the leveling device comprises three layers. The first layer is a lower transition plate connected to the vehicle body; the second layer is a middle transition plate mounted on a rotation axis on the lower transition plate, representing a rotatable straight line; the third layer is an upper transition plate mounted on a rotation axis on the middle transition plate, also representing a rotatable straight line. The radar is mounted on the upper transition plate, and by rotating and adjusting the middle and upper transition plates, the transition plates on the radar's mounting surface are positioned on a horizontal plane.

[0007] (III) Beneficial Effects

[0008] The radar automatic leveling device provided by the above technical solution has a simple structure, is easy to manufacture, is lightweight, and can bear a large weight.

Detailed Implementation

[0013] To make the objectives, contents, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0014] See attached document Figure 1 As shown, after using the radar automatic leveling device 2 designed in this invention on the reconnaissance vehicle 1, the radar 3 is installed on the radar automatic leveling device 2. The radar automatic leveling device 2 can ensure that the installation surface of the radar 3 is in a horizontal state when the reconnaissance vehicle 1 is on any inclined surface.

[0015] See attached document Figure 2 As shown: The radar automatic leveling device comprises a three-layer structure, from bottom to top as follows: First layer: Lower transition plate 13 is connected to the vehicle body; Second layer: Middle transition plate 8 is mounted on the first rotating shaft 6 on the lower transition plate 13, representing a rotatable straight line; Third layer: Upper transition plate 5 is mounted on the second rotating shaft on the middle transition plate 8, representing a rotatable straight line; Radar 3 is mounted on the upper transition plate 5, and by rotating and adjusting the middle transition plate 8 and the upper transition plate 5, the mounting surface of radar 3—the upper transition plate 5—is positioned on a horizontal plane.

[0016] A first support seat 7 is installed on the front and rear sides of the right end surface of the lower transition plate 13. A pair of angular contact bearings are installed in the mounting holes on the upper part of the first support seat 7. The first rotating shaft 6 is L-shaped, and its lower end is connected to the support seat 7 through the angular contact bearing. The upper end is equipped with an intermediate transition plate 8.

[0017] A first tapered roller bearing housing 12 is installed on the left end surface of the lower transition plate 13. A first tapered roller bearing 11 is installed inside the first tapered roller bearing housing 12. A first T-nut 10 is installed inside the first tapered roller bearing 11. A first T-screw 9 is installed inside the first T-nut 10. A first trapezoidal screw gear 14 is installed at the lower end of the first T-screw 9, and a first needle roller bearing shaft is installed at the upper end. A first needle roller bearing is installed on the first needle roller bearing shaft. The first needle roller bearing and the first rolling track cooperate and can roll in the first rolling track. The first rolling track is installed on the intermediate transition plate 8.

[0018] A first motor 16 is mounted on the middle surface of the lower transition plate 13, and a first motor gear 15 is mounted on the first motor 16. The first motor gear 15 and the first trapezoidal lead screw gear 14 are engaged.

[0019] Because the first T-shaped lead screw 9, the intermediate transition plate 8, and the first rolling track are in tandem, they can only move up and down and cannot rotate. When the first motor 16 is energized and rotates, it drives the first motor gear 15, the first trapezoidal lead screw gear 14, and the first T-shaped nut 10 to rotate, thereby driving the first T-shaped lead screw 9 to move up and down. The up and down movement of the first T-shaped lead screw 9 drives the intermediate transition plate 8 to rotate around the angular contact bearing on the first support seat 7.

[0020] like Figure 2 As shown, a first spring 17 is installed between the lower transition plate 13 and the intermediate transition plate 8 to eliminate the backlash between the first T-screw 9 and the first T-nut 10, thereby improving the leveling accuracy.

[0021] A second support seat is installed on each of the left and right sides of the intermediate transition plate 8. A pair of angular contact bearings 21 are installed in the mounting holes at the top of the second support seat. The second rotating shaft is L-shaped, and its lower end is connected to the second support seat through the angular contact bearings 21. The upper end is equipped with the transition plate 5.

[0022] A tapered roller bearing housing is installed on the surface of the intermediate transition plate 8. A tapered roller bearing is installed inside the tapered roller bearing housing. A T-nut is installed inside the tapered roller bearing. A T-screw is installed inside the T-nut. A trapezoidal screw gear is installed at the lower end of the T-screw. A second needle roller bearing shaft 19 is installed at the upper end. A second needle roller bearing 18 is installed on the second needle roller bearing shaft 19. The second needle roller bearing 18 cooperates with the second rolling track 20 and can roll within the second rolling track 20. The second rolling track 20 is installed on the upper transition plate 5.

[0023] A second motor is mounted on the surface of the intermediate transition plate 8, and a second motor gear is mounted on the second motor. The second motor gear and the second trapezoidal lead screw gear are engaged.

[0024] A second spring is installed between the upper transition plate 5 and the middle transition plate 8 to eliminate the thread gap between the second T-type lead screw and the second T-type nut, thereby achieving higher leveling accuracy.

[0025] A dual-axis tilt sensor 4 is installed at the bottom of the upper transition plate 5 to sense whether the leveling device is level.

[0026] Based on the above leveling device, the leveling process is as follows:

[0027] A dual-axis tilt sensor 4 is fixed on the upper transition plate 5 and has two sensitive axes, an x-axis and a y-axis. The x-axis is perpendicular to the second rotation axis of the upper transition plate 5, and the y-axis is parallel to the second rotation axis of the upper transition plate 5. The second rotation axis of the upper transition plate 5 is perpendicular to the first rotation axis of the intermediate transition plate 8. The intermediate transition plate 8 rotates around the first rotation axis, which can adjust the y-axis to be parallel to the ground; when the intermediate transition plate 8 is fixed and the upper transition plate 5 rotates around the second rotation axis, the parallelism of the y-axis to the ground remains unchanged, and the x-axis remains parallel to the ground, thus achieving leveling.

[0028] When the reconnaissance vehicle is parked on a sloping road, the x-axis and y-axis of the dual-axis tilt sensor 4 detect the angle between itself and the ground plane. The first motor 16 drives the first motor gear 15, the first T-shaped lead screw gear 14, and the first T-shaped nut 10 to rotate. Since the first T-shaped nut 10 can only rotate and not move up and down, and the first T-shaped lead screw, in conjunction with the first rolling track and the intermediate transition plate 8, cannot rotate but can only move up and down, the rotation of the first T-shaped nut drives the first T-shaped lead screw to move up and down, thereby causing the intermediate transition plate 8 to rotate around the first support base 7, achieving parallelism between the y-axis of the dual-axis tilt sensor 4 and the ground. Similarly, the second motor on the intermediate transition plate 8 operates, thereby causing the upper transition plate 5 to rotate around the second support base, achieving parallelism between the x-axis of the dual-axis tilt sensor 4 and the ground, thus placing the upper transition plate on a horizontal plane and achieving leveling.

[0029] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
