[0001] This invention belongs to the field of protective shield technology, and in particular relates to a portable millimeter-wave active denial riot shield. Background Technology

[0002] Blast shields are typically made of lightweight materials such as polycarbonate, PC, and fiberglass. High-quality PC shields offer higher transparency, lighter weight, and are more impact-resistant and durable. They can withstand attacks from small-caliber firearms, projectiles, and sharp objects, as well as corrosion from acids and other chemicals. They offer strong protection, are securely installed, and are easy to operate. However, during use, users often cannot withstand the impact force, causing the shield to tip over and lose its protective function. This paper proposes a device to effectively prevent blast shields from tipping over. Summary of the Invention

[0013] Beneficial effects

[0014] This invention provides a portable millimeter-wave active denial riot shield, which has the following advantages compared with the prior art:

[0015] 1. Relevant technicians control the motor to drive the transmission gear meshing with its output gear, which in turn drives the guide rod fixedly connected to it to rotate. This, in turn, drives the worm gears at both ends of the guide rod to rotate synchronously. The worm gears then drive the worm wheel meshing with them to rotate, which in turn drives the screw A fixedly connected to it to rotate. Screw A then drives the threaded slide cylinder on it to begin linear motion, which in turn drives the hinged support rod to begin synchronous motion. This, in turn, causes the shield body hinged to it to move in a circular motion around the hinge point with the shell as the fulcrum. When the shield body is perpendicular to the shell, the control screw A stops rotating. At this point, the relevant technicians can stand on the shell and use the shield to protect themselves, effectively preventing the shield from tipping over due to impact. Furthermore, if the shield height is insufficient to provide adequate protection for the user, the relevant technicians... The personnel stretch the lifting plate longitudinally, causing part of the plate inside the shield to extend out. When the height is sufficient, the relevant technicians manually turn the screws to enter the holes on both sides of the lifting plate, thereby limiting the lifting plate and preventing it from sliding. At this time, the relevant technicians can stand on the shell and observe the front through the mesh plate on the lifting plate. When danger is observed, the relevant technicians close the glass cover on the mesh plate to prevent liquids and other debris from passing through the shield and causing injury to the user. At the same time, the relevant technicians can observe the external situation through the mesh plate to determine whether it is necessary to use the millimeter wave transmitting module to counter the relevant target. The millimeter wave transmitting module emits high-power millimeter waves to irradiate the crowd, acting on the nerves of the human skin, producing a strong pain in a short time, causing the target to spontaneously avoid it. The action time and power density can be reasonably controlled, and it will not cause permanent damage to the human body.

[0016] 2. Place this device on a soft surface. When screw A rotates, it drives pulley A, which is fixedly connected to it, to rotate. This pulley A drives the belt connected to it to rotate, which in turn drives pulley B, which is also connected to it, to rotate synchronously. This pulley B drives screw B, which is fixedly connected to it, to rotate synchronously. This screw B drives the slide cylinder, which is threaded to it, to rotate synchronously. This slide cylinder drives the push rod, which is hinged to it, to move synchronously. This push rod pushes the pressure rod, which is hinged to it, to make it move in a circle around the hinge point with the shell. This causes the spikes at the top of the pressure rod to move synchronously, so that the spikes penetrate the ground, thus connecting the device to the ground and effectively preventing the shield from tipping over when impacted.

[0017] 3. Relevant technicians pull the horizontal plate, causing the horizontal plate to rotate synchronously with the connecting rods A and B that are hinged to it. When connecting rods A and B are perpendicular to the shell, tighten the fastening bolts on them. When the relevant technicians stand on the shell, they can strengthen the connection with the ground through the spikes at the bottom of the horizontal plate. At the same time, when there are restrictions in the usage environment, the shield can be used in a folded state, and the user can use the shield to protect themselves by holding the spikes.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0027] Please refer to Figures 1-6, which illustrate a portable millimeter-wave active denial riot shield according to one embodiment of the present invention. The shield includes a housing 101 and further comprises:

[0028] Support component 2, for providing support for the shield; and adjustment component 3, for adjusting the height of the shield;

[0029] The support assembly 2 includes a shield body 201, support rods 202, a slide cylinder 203, and a screw A204. The shield body 201 is hinged to the housing 101 via a hinge seat at its bottom end. The two support rods 202 are respectively hinged to the shield body 201 on both sides. The other ends of the two support rods 202 are respectively hinged to the slide cylinder 203 via hinge seats on them. The slide cylinder 203 is slidably connected to the housing 101. The screw A204 is threadedly connected to the axis of the slide cylinder 203. The screw A204 is rotatably connected to the housing 101 within the housing 101. The shield body 201 is connected to the adjustment assembly 3.

[0030] Specifically, worm gears 205 are fixedly connected to the two screws A204 respectively, and worms 206 are meshed with the bottom of the two worm gears 205. The two worms 206 are fixedly connected to the guide rod 207. The guide rod 207 is rotatably connected to the housing 101 in the housing 101. The housing 101 is provided with an anti-slip pedal. The screws A204 are connected to the connecting assembly 5.

[0031] Specifically, a transmission gear 208 is fixedly connected to the guide rod 207, and the transmission gear 208 meshes with the output gear of the motor 209. The motor 209 is fixedly connected to the housing 101 in the housing 101.

[0032] Specifically, the adjustment component 3 includes a lifting plate 301, a mesh plate 302, a millimeter-wave transmitting module 303, and screws 304. The lifting plate 301 is slidably connected to the shield body 201. Threaded holes are provided on both sides of the shield body 201, and screws 304 are threadedly connected to the threaded holes. Multiple wide holes corresponding to the screws 304 are provided on both sides of the lifting plate 301. The mesh plate 302 is fixedly connected to the lifting plate 301. A glass cover plate is slidably connected to the mesh plate 302. The multiple millimeter-wave transmitting modules 303 are fixedly connected to the shield body 201.

[0033] Specifically, the millimeter-wave transmitting module 303 has a built-in traveling wave tube, which converts electrical energy into electromagnetic energy and outputs millimeter waves. The traveling wave tube is connected to a feed horn and a reflector antenna, which radiates the millimeter waves output by the traveling wave tube to the target location with high efficiency and meets a certain power density.

[0034] In this embodiment of the invention, a technician controls a motor 209 to drive a transmission gear 208 meshing with its output gear to rotate. This causes the transmission gear 208 to drive a guide rod 207 fixedly connected to it to rotate. The guide rod 207 then drives the worm gears 206 at both ends to rotate synchronously. The worm gears 206 then drive the worm wheel 205 meshing with them to rotate. The worm wheel 205 then drives the screw A204 fixedly connected to it to rotate. The screw A204 then drives the threaded slide cylinder 203 to perform linear motion, which in turn drives the hinged support rod 202 to move synchronously. The support rod 202 then drives the hinged shield 201 to perform circular motion around the hinge point with the housing 101. When the shield 201 is perpendicular to the housing 101, the screw A204 stops rotating. At this point, the technician can stand on the housing 101 and use the shield to protect themselves, effectively preventing the shield from tipping over due to impact. Furthermore, when the shield height is insufficient to provide adequate protection for the user... When sufficient protection is provided, the relevant technicians stretch the lifting plate 301 longitudinally, causing part of the lifting plate 301 to extend out of the shield body 201. When the height is sufficient, the relevant technicians manually turn the screw 304, causing the screw 304 to enter the holes on both sides of the lifting plate 301, thereby limiting the lifting plate 301 and preventing it from sliding. At this time, the relevant technicians can stand on the shell 101 and observe the front through the mesh plate 302 on the lifting plate 301. When danger is observed, the relevant technicians close the glass cover on the mesh plate 302 to prevent liquids and other debris from passing through the shield and causing injury to the user. At the same time, the relevant technicians can observe the external situation through the mesh plate 302 to determine whether it is necessary to use the millimeter wave emission module 303 to counter the relevant target. The millimeter wave emission module 303 emits high-power millimeter waves to irradiate the crowd, acting on the nerves of the human skin, producing a strong pain sensation in a short time, causing the target to spontaneously avoid it. The action time and power density can be reasonably controlled, and no permanent damage to the human body will be caused.

[0035] Specifically, the connecting component 5 includes a pulley A501, a belt 502, and a pulley B503. The pulley A501 is fixedly connected to the screw A204 on either side. The belt 502 is drivenly connected to the pulley A501, and the other end of the belt 502 is drivenly connected to the pulley B503.

[0036] Specifically, a screw B504 is fixedly connected to the shaft of the pulley B503. The screw B504 is rotatably connected to the housing 101 in the housing 101. A slide cylinder 505 is threadedly connected to the screw B504. The slide cylinder 505 is slidably connected to the housing 101.

[0037] Specifically, the slide cylinder 505 is hinged to the push rod 506 via a hinge seat on it. The other end of the push rod 506 is hinged to the pressure rod 507. The pressure rod 507 is hinged to the housing 101. The other end of the pressure rod 507 is hinged to a spike 508. A fastening screw is connected at the hinge point between the pressure rod 507 and the spike 508.

[0038] In this embodiment of the invention, the device is placed on a soft surface. When the screw A204 rotates, it drives the pulley A501 fixedly connected to it to rotate, which in turn drives the belt 502 connected to it to rotate. The belt 502 drives the pulley B503 connected to it to rotate synchronously, which in turn drives the screw B504 fixedly connected to it to rotate. The screw B504 drives the slide cylinder 505 threaded to it to rotate synchronously, which in turn drives the push rod 506 hinged to it to move synchronously. The push rod 506 pushes the pressure rod 507 hinged to it to move in a circular motion around the hinge point with the housing 101. The pressure rod 507 drives the spike 508 at its top to move synchronously, which causes the spike 508 to penetrate the ground, thus connecting the device to the ground and effectively preventing the shield from tipping over when impacted.

[0039] Specifically, the connecting rod assembly 4 includes connecting rod A401, connecting rod B402, cross plate 403, and spikes 404. One end of the housing 101 is hinged to connecting rod A401, and connecting rod A401 is hinged to cross plate 403 through its upper hinge seat. The other end of the cross plate 403 is hinged to connecting rod B402, and the other end of connecting rod B402 is hinged to housing 101. Multiple spikes 404 are fixedly connected to the cross plate 403.

[0040] In this embodiment of the invention, a technician pulls the horizontal plate 403, causing the horizontal plate 403 to drive the connecting rods A401 and B402, which are hinged to it, to rotate synchronously. When the connecting rods A401 and B402 are perpendicular to the housing 101, the fastening bolts on them are tightened. When the technician stands on the housing 101, the connection with the ground can be strengthened by the spikes 404 at the bottom of the horizontal plate 403. At the same time, when there are restrictions in the usage environment, the shield can be used to protect the user by holding the spikes 404 when the shield is in the folded state.
