Description

Technical Field

[0001] The utility model relates to the technical field of military equipment and in particular to an automatic controller for an antenna of a wheeled armored vehicle. Background Art

[0002] The antenna of the Armed Police Wheeled Anti-riot Armored Vehicle is mainly composed of four whip-shaped antennas. Each antenna has the same structure and is connected to the rear base of the roof of the anti-riot armored vehicle through threaded segments. The antenna base of the anti-riot armored vehicle can be manually adjusted in the front and rear directions. The operator needs to stand on the roof, unplug the fixing bolt, and select the limited 6 (3 front and 3 rear) limited holes to adjust the antenna direction.

[0003] At present, in the armed police force's diversified missions, the battlefield electromagnetic environment is complex and there is a lot of interference. When the anti-riot armored vehicle squad conducts radio communications, directional communication is an effective measure to enhance the communication effect. Since the adjustment of the antenna direction for directional communication requires the radio operator to stand outside the vehicle to operate, it does not meet the requirements of battlefield protection for personnel, nor does it meet the actual combat requirements of rapid arrival and precise control. It is likely to cause delays, missed opportunities, and even cause our radio operators to be attacked. Therefore, we propose an automatic antenna controller for wheeled armored vehicles to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0026] The present application provides an automatic controller for the antenna of a wheeled armored vehicle, which is mainly used to solve the problem that in the prior art, the operator needs to stand outside the vehicle to operate the antenna for directional communication, which does not meet the requirements of battlefield protection for personnel, nor does it meet the actual combat requirements of rapid arrival and precise control, and is likely to cause delays, missed opportunities, and even cause our operator to be attacked. The following technical solutions are provided. Figure 1-Figure 5 Make a detailed description:

[0027] An automatic controller for an antenna of a wheeled armored vehicle, comprising:

[0028] A disc seat 1 is arranged on the top of the wheeled armored vehicle, and a mounting plate 2 is fixedly arranged in the middle of the top of the disc seat 1;

[0029] A whip antenna 3 and an angle adjustment mechanism 4, wherein the angle adjustment mechanism 4 is used for adjusting the deflection angle of the whip antenna 3. The angle adjustment mechanism 4 comprises a servo motor 401 mounted on one side of the disc seat 1, wherein the output shaft of the servo motor 401 passes through one of the mounting plates 2 and is connected to a driving gear 402, and a rotating rod 403 is rotatably connected to the other mounting plate 2, a deflection plate 404 is fixedly arranged at the end of the rotating rod 403, the whip antenna 3 is fixedly arranged on the top of the deflection plate 404, and a driven gear 405 is fixedly arranged on one side of the deflection plate 404, and the driven gear 405 is meshed with the driving gear 402;

[0030] The limiting member 5 is arranged at the front and rear sides of the mounting plate 2 and is used to limit the maximum deflection angle of the whip antenna 3;

[0031] The locking mechanism 6 is used to lock the whip antenna 3 at a specified deflection angle.

[0032] The specific implementation process and principle of the wheeled armored vehicle antenna automatic controller:

[0033] When in use, turn on the main power switch of the armored vehicle, turn on the shortwave radio, turn on the power switch of the antenna controller according to actual communication and needs, operate the armored vehicle control panel, start the motor, drive the active gear 402 to rotate, and the active gear 402 engages with the driven gear 405, thereby realizing the deflection of the deflection plate 404, and then realizing the deflection of the whip antenna 3. The maximum deflection angle of the whip antenna 3 is limited by the limiter 5 to prevent excessive deflection. After adjusting to a suitable deflection angle, the whip antenna 3 is locked at a specified position by the locking mechanism 6 to ensure the stability of communication.

[0034] like Figure 1 As shown, in some embodiments, a tube cover 7 is fixedly provided on the top of the disc seat 1, and a rectangular notch 701 is constructed on the top of the tube cover 7. The deflection plate 404 slides and inserts into the rectangular notch 701. More specifically, the tube cover 7 is designed to protect the internal angle adjustment mechanism 4 from the external environment.

[0035] like Figure 2 As shown, in some embodiments, the limit member 5 includes a first limit plate 501 fixedly mounted on one end side of the mounting plate 2, and a second limit plate 502 fixedly mounted on the other end side of the mounting plate 2. The first limit plate 501 is horizontally arranged, and the angle between the second limit plate 502 and the first limit plate 501 is 160°. More specifically, the limit member 5 is designed to ensure that the whip antenna 3 does not exceed a preset range (the adjustment angle range is 0-160° forward) when adjusting the deflection angle, thereby protecting the antenna and the adjustment mechanism from damage and ensuring that the aerodynamic performance of the vehicle is not affected.

[0036] like Figure 2 As shown, in some embodiments, pressure sensors 503 are installed at positions on the surfaces of the first limit plate 501 and the second limit plate 502 corresponding to the deflection plate 404. More specifically, when the deflection plate 404 contacts the first limit plate 501 or the second limit plate 502 when adjusting the angle, the pressure sensor 503 detects a pressure signal. The pressure sensor 503 provides real-time feedback to the control system. Once a predetermined pressure threshold is detected, the system can automatically stop the operation of the servo motor 401 to prevent the servo motor 401 from burning out due to inability to rotate.

[0037] like Figure 5As shown, in some embodiments, the locking mechanism 6 includes a fixed plate 601 fixedly mounted on one side of the deflection plate 404, and a side annular array of pin holes 6011 is configured on the side of the fixed plate 601. A mounting tube 602 is fixedly embedded on the surface of the mounting plate 2, and a latch 603 is slidably inserted through one end of the mounting tube 602 close to the fixed plate 601. The latch 603 is adapted in size to the pin hole 6011, and a magnet column 604 is fixedly mounted on one end of the latch 603 located inside the mounting tube 602. A spring 605 is connected between the magnet column 604 and the tube wall of the mounting tube 602. The spring 605 is sleeved on the surface of the latch 603, and the inner wall of the mounting tube 602 is fixedly mounted on the outer wall of the mounting tube 602. An electromagnetic coil 606 is embedded at the other end. More specifically, when the deflection plate 404 needs to be locked, the electromagnetic coil 606 is energized. At this time, the electromagnetic coil 606 generates a magnetic field to push the magnet column 604 to move and compress the spring 605, pushing the latch 603 to move outward, and the head of the latch 603 enters the corresponding pin hole 6011 on the fixed disk 601, locking the position of the deflection plate 404. When the deflection angle needs to be adjusted, the electromagnetic coil 606 is deenergized, the magnetic field disappears, and under the action of the spring 605, the latch 603 is pulled out of the pin hole 6011, so that the deflection plate 404 is unlocked and can be freely rotated to a new position.

[0038] like Figure 5 As shown, in some embodiments, the number of pin holes 6011 is eight. More specifically, the eight pin holes 6011 are evenly distributed on the edge of the fixed plate 601 to form a circular array. Each pin hole 6011 represents a predetermined deflection angle (45°). The operator or the automatic control system can select the most suitable pin hole 6011 for locking as needed, thereby achieving precise angle adjustment. In actual combat, commonly used angles include: front 45°, rear 45°, vertical and front 0°, achieving the most convenient directional communication that meets actual combat needs.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
