[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 protective device for a vehicle-mounted UAV countermeasure device, the structure of which is as follows: Figure 1 - Figure 3 As shown, the vehicle-mounted drone countermeasure device includes a countermeasure mechanism 1; the protective device for the vehicle-mounted drone countermeasure device includes a buffer mechanism 2 and a protective mechanism 3.

[0026] The countermeasure mechanism 1 includes a bracket 12 disposed on the top of a vehicle body 11 , and a drone detector 13 and a drone countermeasure 14 are disposed on the bracket 12 .

[0027] The buffer mechanism 2 is disposed at the bottom of the bracket 12 , and is used to mitigate the bumping of the bracket 12 .

[0028] The protection mechanism 3 is provided on the top of the bracket 12 and is used to mitigate the impact of wind.

[0029] When in use, the drone detector 13 continuously monitors the surrounding airspace. When the detector detects the signal of the drone, the drone countermeasure 14 is activated to take interference or other countermeasures against the drone. The bracket 12 is installed on the top of the vehicle body 11 to provide support for the drone detector 13 and the countermeasure. The buffer mechanism 2 is located at the bottom of the bracket 12. When the vehicle body 11 encounters bumps on uneven roads during driving, the buffer mechanism 2 comes into play. It absorbs and disperses the impact force generated by the bumps, thereby slowing down the vibration transmitted to the bracket 12, reducing the violent shaking of the bracket 12, protecting the equipment installed on the bracket 12 from damage due to excessive vibration, and ensuring its normal operation. The protective mechanism 3 is set on the top of the bracket 12. When encountering strong winds, the protective mechanism 3 reduces the direct impact of the wind on the bracket 12 by changing the direction of the wind, dispersing the wind force or providing a certain blocking effect, thereby reducing wind resistance and ensuring the structural stability of the bracket 12.

[0030] In the present invention, the buffer mechanism 2 can absorb and disperse the impact force generated by bumps, thereby slowing down the vibration transmitted to the bracket 12, reducing the violent shaking of the bracket 12, and protecting the drone detector 13 and the drone countermeasure 14 from damage due to excessive vibration. The protective mechanism 3 reduces the direct impact force of the wind on the bracket 12 by changing the direction of the wind, dispersing the wind force and providing a certain blocking effect, thereby reducing the possibility of damage to the drone detector 13 and the drone countermeasure 14.

[0031] To reduce the vibration of the bracket 12, please refer to Figure 1 In a preferred embodiment, the buffer mechanism 2 includes a damper 21 arranged between the bracket 12 and the vehicle body 11, the top end of the damper 21 is connected to the bracket 12, and the bottom end of the damper 21 is connected to the vehicle body 11. A spring 22 is provided on the damper 21, and the spring 22 is at its original length.

[0032] During use, when vehicle body 11 travels over uneven roads and experiences bumps, bracket 12 moves up and down. This downward movement of bracket 12 applies pressure to damper 21, creating resistance within the damping medium, slowing the downward movement of bracket 12. Simultaneously, the downward movement of bracket 12 compresses spring 22, which is initially positioned within damper 21. This compression and stored elastic potential energy in spring 22 generate an upward reaction force, resisting any further downward movement of bracket 12.

[0033] As bracket 12 moves upward, the damping medium within damper 21 again creates resistance, slowing the bracket's upward motion. At this point, the compressed spring 22 releases its elastic potential energy, pushing bracket 12 upward. However, the damping action of damper 21 limits the speed at which the spring 22 pushes bracket 12 upward, resulting in smoother movement. The damping effect of damper 21 and the elastic action of spring 22 work together to effectively absorb and mitigate the energy transferred to bracket 12 from the jolting of vehicle body 11, reducing the degree of jolting on bracket 12 and protecting the equipment mounted on bracket 12.

[0034] To mitigate the impact of wind, please refer to Figure 1 In a preferred embodiment, the protective mechanism 3 includes a protective plate 31 and a protective cover 32 provided on the top of the vehicle body 11, the protective plate 31 is located at the head of the bracket 12, and the protective cover 32 is located at the tail of the bracket 12. The side of the protective cover 32 close to the protective plate 31 is open, and the vehicle body 11 is provided with a driving component 4 for driving the protective cover 32 to slide so that the protective cover 32 abuts against the protective plate 31.

[0035] During use, under normal circumstances, the protective plate 31 is located at the head of the bracket 12, the protective cover 32 is located at the tail of the bracket 12, and the side of the protective cover 32 close to the protective plate 31 is open. When encountering situations such as strong winds that require protection, the drive assembly 4 on the vehicle body 11 is started. The drive assembly 4 generates a driving force to push the protective cover 32 to slide along the top of the vehicle body 11. As the protective cover 32 slides, it gradually approaches the protective plate 31 and finally abuts against the protective plate 31. At this time, the protective plate 31 and the protective cover 32 abutting against the protective plate 31 together form a continuous protective structure, blocking the wind from directly impacting the bracket 12, thereby reducing the impact of the wind on the bracket 12 and protecting the drone detector 13 and drone countermeasure 14 on the bracket 12.

[0036] To drive the protective cover 32 to move, please refer to Figure 1 In a preferred embodiment, the driving assembly 4 includes an electric push rod disposed on the top of the vehicle body 11 , and the output shaft of the electric push rod is connected to a side of the protective cover 32 away from the protective plate 31 .

[0037] During use, when the protective cover 32 needs to be driven to slide, since the output shaft of the electric push rod is connected to the side of the protective cover 32 away from the protective plate 31, the linear motion of the output shaft directly drives the protective cover 32 to slide along the top of the vehicle body 11. By controlling the extension and extension length and direction of the electric push rod, the sliding position of the protective cover 32 can be accurately controlled, and the protective cover 32 can be abutted or separated from the protective plate 31 to achieve the purpose of protection or opening.

[0038] To reduce the possibility of damage to the protective cover 32 and the protective plate 31, please refer to Figure 1 In a preferred embodiment, an elastic layer 33 is provided on the side of the protective plate 31 close to the protective cover 32.

[0039] During use, when the drive assembly 4 pushes the protective cover 32 to slide and abuts the protective plate 31, the elastic layer 33 on the protective plate 31 first contacts the protective cover 32. Since the elastic layer 33 is elastic, it can play a buffering role. In the process of the protective cover 32 abutting the protective plate 31, the elastic layer 33 can absorb part of the impact force and reduce the collision and wear between the protective cover 32 and the protective plate 31. In addition, the elastic layer 33 can also fill the tiny gaps that may exist between the protective cover 32 and the protective plate 31, enhance the sealing of the protection, and further improve the effect of mitigating wind impact. Under the impact of strong winds, the elastic deformation of the elastic layer 33 can also play a certain shock-absorbing role, reducing the impact of vibration on the overall protective structure, thereby more effectively protecting the drone detector 13 and the drone countermeasure 14.

[0040] To reduce wind impact, please refer to Figure 2 In a preferred embodiment, the protective plate 31 is streamlined.

[0041] During use, when the airflow hits the protective plate 31, the airflow can flow smoothly along its surface due to the streamlined shape of the protective plate 31. The streamlined design can reduce the separation and eddy currents generated by the airflow on the surface of the protective plate 31, thereby reducing wind resistance. This means that the impact force of the wind on the protective plate 31 will be reduced, allowing the protective plate 31 to more effectively resist the impact of the wind while reducing the vibration and noise caused by wind resistance. Smaller wind resistance also helps to reduce the load borne by the entire protective mechanism 3, enhance its stability and reliability, and thus better protect the drone detector 13 and the drone countermeasure 14.

[0042] To reduce the possibility of dust entering the protective cover 32, please refer to Figure 2 In a preferred embodiment, the outer sides of the protective plate 31 and the protective cover 32 are both provided with a dust-proof layer.

[0043] During use, when there is dust in the external environment, dust particles will move with the air flow. Since the outer surface of the protective plate 31 and the protective cover 32 is provided with a dust-proof layer, its surface is relatively smooth, making it difficult for dust particles to adhere, thereby keeping the surface of the protective plate 31 and the protective cover 32 relatively clean, reducing the impact of dust on the drone detector 13 and the drone countermeasure 14.

[0044] In order to discharge the heat in the protective cover 32 in time, please refer to Figure 3In a preferred embodiment, a heat dissipation hole 34 is provided on one side of the protective cover 32 close to the rear of the vehicle body 11 , and a filter 35 is provided on the heat dissipation hole 34 .

[0045] During use, drone detector 13 and drone countermeasure 14 generate heat, raising the ambient temperature. Heat dissipation holes 34 are provided to allow hot air to escape from the interior of protective cover 32, promoting air circulation and dissipating heat, thereby preventing damage or performance degradation of drone detector 13 and drone countermeasure 14 due to overheating.

[0046] The function of the filter 35 is to prevent dust and foreign matter from entering the protective cover 32 while allowing air to pass through. When air passes through the heat dissipation holes 34, the filter 35 intercepts larger particles and foreign matter, preventing them from entering the protective cover 32, thereby protecting the equipment inside from dust and foreign matter while not affecting the heat dissipation effect.

[0047] To facilitate the disassembly and assembly of the filter 35, please refer to Figure 3 In a preferred embodiment, a countersunk groove 36 is provided on the protective cover 32 , and the filter 35 is threadedly connected to the countersunk groove 36 .

[0048] During use, when the filter 35 needs to be installed, align the threads of the filter 35 with the threads in the countersunk groove 36. By rotating the filter 35, its threads are gradually screwed in along the threads of the countersunk groove 36. During the rotation process, the filter 35 continues to penetrate deeper into the countersunk groove 36 until it is fully installed in place. The design of the countersunk groove 36 ensures that the filter 35 will not protrude from the surface of the protective cover 32 after installation, thereby maintaining the flatness of the appearance of the protective cover 32. At the same time, it also provides a certain degree of protection for the filter 35 and reduces the risk of direct collision of the filter 35. The threaded connection provides a stable fixing method, which can ensure that the filter 35 will not fall off easily during use, and is easy to disassemble and replace for cleaning or maintenance.

[0049] To reduce the possibility of the filter 35 becoming loose, please refer to Figure 3 In a preferred embodiment, a slot 37 is provided on the protective cover 32, and the slot 37 is located on one side of the filter 35. An anti-loosening tooth block 38 is clamped in the slot 37, and an anti-loosening tooth ring 39 is provided on the filter 35 to engage with the anti-loosening tooth block 38.

[0050] During use, after the filter screen 35 is threadedly installed in the countersunk groove 36 and tightened into place, the anti-loosening tooth block 38 is engaged in the locking groove 37 of the protective cover 32. At this time, the anti-loosening tooth ring 39 mounted on the filter screen 35 and the anti-loosening tooth block 38 engage with each other. If the filter screen 35 tends to loosen, such as due to vibration or other external forces, the filter screen 35 may have a slight tendency to rotate. Since the anti-loosening tooth ring 39 and the anti-loosening tooth block 38 engage with each other, the anti-loosening tooth block 38 will prevent the anti-loosening tooth ring 39 from rotating, thereby limiting the rotation of the filter screen 35 and preventing the filter screen 35 from loosening.

[0051] In order to better understand the present invention, the following Figure 1 - Figure 3 The working principle of the technical solution of the protective device for a vehicle-mounted drone countermeasure device of the utility model is described in detail: the drone detector 13 continuously monitors the surrounding airspace. When the detector detects the signal of the drone, the drone countermeasure 14 is activated to take interference or other countermeasures against the drone. The bracket 12 is installed on the top of the vehicle body 11 to provide support for the drone detector 13 and the countermeasure. The buffer mechanism 2 is located at the bottom of the bracket 12. When the vehicle body 11 encounters bumps on an uneven road surface during driving, the buffer mechanism 2 comes into play. It absorbs and disperses the impact force generated by the bumps, thereby slowing down the vibration transmitted to the bracket 12, reducing the violent shaking of the bracket 12, protecting the equipment installed on the bracket 12 from damage due to excessive vibration, and ensuring its normal operation. The protective mechanism 3 is set on the top of the bracket 12. When encountering strong winds, the protective mechanism 3 reduces the direct impact force of the wind on the bracket 12 by changing the direction of the wind, dispersing the wind force or providing a certain blocking effect, thereby reducing wind resistance and ensuring the structural stability of the bracket 12.

[0052] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
