[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0025] The utility model provides a posture adjustment mechanism for a UAV interference countermeasure device, the structure of which is as follows: Figure 1 - Figure 2 As shown, it includes a support 1, a bracket 3, an antenna 4 and a fixing component 5.
[0026] The support 1 is arranged on the top of the vehicle body 2 .
[0027] The bracket 3 is rotatably connected to the support 1 .
[0028] There are multiple antennas 4 , and the multiple antennas 4 are arranged on the bracket 3 at intervals along the length direction of the bracket 3 .
[0029] The fixing assembly 5 is provided on the support 1 and is used to fix the bracket 3 so that the antenna 4 is in a horizontal state or a vertical state.
[0030] When in use, the support 1 is installed on the top of the vehicle body 2 to provide support for the entire device. The bracket 3 is rotatably connected to the support 1, so that the bracket 3 can rotate around the connection point. When the antenna 4 needs to be adjusted to a horizontal state, the fixing component 5 is released from the bracket 3, and then the bracket 3 is rotated so that the bracket 3 is in a horizontal position. At this time, the multiple antennas 4 are also in a horizontal state. After adjustment, the bracket 3 is fixed to the support 1 using the fixing component 5 to keep the horizontal state of the antenna 4 stable. Similarly, when the antenna 4 needs to be adjusted to a vertical state, the fixing component 5 is released again, the bracket 3 is rotated to a vertical position, and then the bracket 3 is fixed with the fixing component 5 to keep the antenna 4 in a vertical state.
[0031] In the present invention, when it is needed, the bracket 3 is rotated to make the antenna 4 in a vertical state. After use, the bracket 3 is rotated to make the antenna 4 in a horizontal state, fitting with the top of the vehicle body 2, and fixed with the fixing component 5, thereby lowering the height of the antenna 4, reducing wind resistance, and reducing the possibility of damage to the antenna 4.
[0032] To facilitate the adjustment of the antenna 4 angle, please refer to Figure 1 In a preferred embodiment, the support 1 includes a horizontal plate 11 arranged on the top of the vehicle body 2, two vertical plates 12 are provided on the horizontal plate 11, a rotating rod 13 is provided between the two vertical plates 12, and the bracket 3 is rotatably connected to the rotating rod 13.
[0033] During use, the horizontal plate 11 mounted on top of the vehicle body 2 serves as the foundation for the entire support 1, providing a stable support platform. Two vertical plates 12 on the horizontal plate 11 stand opposite each other, with a rotating rod 13 disposed between the two vertical plates 12. The bracket 3 is rotatably connected to the rotating rod 13. Because the rotating rod 13 is fixed between the two vertical plates 12, the rotational movement of the bracket 3 is constrained by the rotating rod 13, allowing stable rotation within a certain range, thereby adjusting the angle of the antenna 4. This structure makes the angle adjustment of the antenna 4 more flexible and stable, while also facilitating precise control of the position of the antenna 4.
[0034] To optimize the structure, please refer to Figure 2 In a preferred embodiment, the bracket 3 includes a vertical frame 31 rotatably connected to the rotating rod 13, and a horizontal frame 32 is provided on the end of the vertical frame 31 away from the rotating rod 13, and the multiple antennas 4 are arranged on the horizontal frame 32 at intervals along the length direction of the horizontal frame 32.
[0035] During use, one end of the vertical frame 31 is rotatably connected to the rotating rod 13, allowing the entire bracket 3 to rotate around the rotating rod 13, thereby adjusting the angle of the antenna 4 mounted on the horizontal frame 32. When the orientation of the antenna 4 needs to be changed, due to the connection between the vertical frame 31 and the rotating rod 13, the vertical frame 31 can drive the horizontal frame 32 and the multiple antennas 4 mounted on the horizontal frame 32 to rotate together. The horizontal frame 32 serves to support the antenna 4. Multiple antennas 4 are arranged at intervals along the length of the horizontal frame 32. This layout allows the antenna 4 to receive or transmit signals at different positions, improving the signal coverage and reception effect.
[0036] To fix the antenna 4, please refer to Figure 2 In a preferred embodiment, the fixing assembly 5 includes a socket 51 provided on one of the vertical plates 12, an insertion rod 52 is passed through the socket 51, and two slots 53 for accommodating the insertion rod 52 are provided on the vertical frame 31 along the rotation direction of the vertical frame 31.
[0037] During use, when it is necessary to fix the bracket 3 to determine the status of the antenna 4, first observe the position of the bracket 3. If the bracket 3 is in a horizontal or vertical position, the socket 51 on the vertical plate 12 is aligned with the corresponding slot 53 on the vertical frame 31. Then, insert the rod 52 into the socket 51 and pass it through the socket 51 into the slot 53 on the vertical frame 31. Due to the restraining effect of the rod 52, the vertical frame 31 cannot continue to rotate. When the rod 52 is inserted into the corresponding slot 53, the vertical frame 31 is fixed in its current position, thereby maintaining the horizontal frame 32 mounted on the vertical frame 31 and the multiple antennas 4 on the horizontal frame 32 in a stable state. If the status of the antenna 4 needs to be adjusted, remove the rod 52 from the slot 53. The bracket 3 can now rotate around the rotating rod 13. After adjusting to the desired angle, insert the rod 52 into the corresponding slot 53 again to secure the bracket 3.
[0038] In order to improve the stability of the insertion rod 52, please refer to Figure 2 In a preferred embodiment, a spring 54 is provided on the insertion rod 52, one end of the spring 54 is connected to the insertion rod 52, and the other end of the spring 54 is connected to the vertical plate 12. The spring 54 is in a stretched state, and the spring 54 causes the insertion rod 52 to have a tendency to slide toward the vertical frame 31.
[0039] During normal use, spring 54 is in a stretched state, with one end connected to the rod 52 and the other end connected to the riser 12. The stretching action of spring 54 exerts a pulling force on rod 52, causing it to consistently slide toward the vertical frame 31. To secure bracket 3, bracket 3 is rotated to a horizontal or vertical position, aligning slot 53 on vertical frame 31 with socket 51 on riser 12. At this point, under the tension of spring 54, rod 52 automatically slides toward vertical frame 31 and inserts into slot 53, quickly securing bracket 3. To adjust the angle of bracket 3, rod 52 is manually removed from slot 53, causing spring 54 to further stretch, storing more elastic potential energy. After adjusting the angle of bracket 3, once slot 53 and socket 51 are aligned again, the tension of spring 54 quickly pulls rod 52 into slot 53, completing the fast and convenient securing operation. The presence of the spring 54 not only improves the convenience of the fixing operation, but also increases the contact pressure between the insertion rod 52 and the slot 53, making the bracket 3 more stable in the fixed state and less likely to rotate accidentally due to external interference.
[0040] To reduce the possibility of antenna 4 jitter, please refer to Figure 2 In a preferred embodiment, an elastic layer is provided on the inner wall of the slot 53 .
[0041] During use, when the rod 52 is inserted into the slot 53 under the tension of the spring 54, the elastic layer on the inner wall of the slot 53 directly contacts the rod 52. The elastic layer is typically made of an elastic material such as rubber or silicone. This layer acts as a buffer, reducing the impact of the rod 52 entering the slot 53 and preventing damage to the rod 52 and slot 53 due to hard collision.
[0042] On the other hand, the elastic layer will deform to a certain extent after the insertion of the rod 52, tightly wrapping the rod 52. This wrapping effect increases the friction between the rod 52 and the slot 53, making the rod 52 more stable in the slot 53 and not easy to loosen or accidentally fall out.
[0043] At the same time, the elastic layer can also accommodate slight variations in the size of the rod 52, ensuring that even if there are certain dimensional errors in the rod 52 during manufacturing or use, a good fixing effect can be achieved. When it is necessary to remove the rod 52 to adjust the angle of the bracket 3, the elasticity of the elastic layer also makes it relatively easy to remove the rod 52, without difficulty due to an overly tight fit.
[0044] In order to make the rod 52 slide into the slot 53 more easily, please refer to Figure 2 In a preferred embodiment, the end of the insertion rod 52 close to the vertical frame 31 is spherical.
[0045] During use, the end of the rod 52 closest to the vertical bracket 31 is spherical, serving as a guide as the rod 52 moves toward the slot 53. The spherical shape makes it easier for the rod 52 to align with the entrance of the slot 53. Even if the socket 51 and the slot 53 are not perfectly aligned, the spherical end can still guide the rod 52 smoothly into the slot 53 to a certain extent through its smooth surface. Once the rod 52 is inserted into the slot 53, the contact area between the spherical end and the slot 53 is relatively small, reducing friction between the rod 52 and the slot 53 and making it easier to remove the rod 52 from the slot 53 when the angle of the bracket 3 needs to be adjusted.
[0046] To facilitate the operation of the plunger 52, please refer to Figure 2 In a preferred embodiment, a handle 55 is provided on the insertion rod 52.
[0047] During use, when the angle of bracket 3 needs to be adjusted, the operator can operate rod 52 by gripping handle 55. The handle provides a convenient location for the operator to grip and apply force. The presence of handle 55 makes operation of rod 52 more convenient and labor-saving, improving the efficiency and accuracy of adjusting the angle of antenna 4.
[0048] To facilitate the installation and removal of antenna 4, please refer to Figure 2In a preferred embodiment, the antenna 4 is threadedly connected to the cross frame 32 .
[0049] To install antenna 4, align the external threads on the bottom of antenna 4 with the internal threads on cross frame 32. Then, rotate antenna 4 until the external threads engage with the internal threads of cross frame 32. This threaded connection also facilitates installation and removal of antenna 4. If antenna 4 needs to be replaced or repaired, it can be easily removed from cross frame 32 by rotating it in the opposite direction.
[0050] To reduce the possibility of antenna 4 becoming loose, please refer to Figure 2 In a preferred embodiment, the antenna 4 is coaxially sleeved with an anti-loosening tooth ring 41, and the cross frame 32 is provided with a slot 42, in which an anti-loosening rack 43 is engaged with multiple anti-loosening tooth rings 41 at the same time.
[0051] During use, after the antenna 4 is fixed to the cross frame 32 by a threaded connection, the anti-loosening rack 43 is clamped into the slot 42 on the cross frame 32. Due to the limitation of the slot 42, the anti-loosening rack 43 cannot move. The anti-loosening rack 43 is engaged with multiple anti-loosening tooth rings 41 at the same time. When the antenna 4 tends to loosen. At this time, the anti-loosening tooth ring 41 tends to rotate with the slight rotation of the antenna 4. However, since the anti-loosening tooth ring 41 is engaged with the anti-loosening rack 43, the anti-loosening rack 43 is fixed in the slot 42 and cannot move, so the rotation of the anti-loosening tooth ring 41 is prevented. Through the interaction between the anti-loosening tooth ring 41 and the anti-loosening rack 43, the antenna 4 is effectively prevented from loosening, ensuring that the antenna 4 can maintain a stable connection state under various working conditions, ensuring the normal reception and transmission of signals.
[0052] In order to better understand the present invention, the following Figure 1 - Figure 2 The working principle of the technical solution of the attitude adjustment mechanism of the UAV interference countermeasure device of the present invention is described in detail: the support 1 is installed on the top of the vehicle body 2 to provide support for the entire device. The bracket 3 is rotatably connected to the support 1 so that the bracket 3 can rotate around the connection point. When the antenna 4 needs to be adjusted to a horizontal state, the fixing component 5 on the bracket 3 is released, and then the bracket 3 is rotated so that the bracket 3 is in a horizontal position. At this time, the multiple antennas 4 are also in a horizontal state. After adjustment, the bracket 3 is fixed to the support 1 by the fixing component 5 to keep the horizontal state of the antenna 4 stable. Similarly, when the antenna 4 needs to be adjusted to a vertical state, the fixing component 5 is released again, the bracket 3 is rotated to a vertical position, and then the bracket 3 is fixed with the fixing component 5 to keep the antenna 4 in a vertical state.
