Description

Technical Field

[0001] This invention relates to the field of electromagnetic properties technology, and in particular to an electrically controlled foldable corner reflector. Background Technology

[0002] Corner reflectors are typical passive targets with a strong backscattered radar cross section (RSS). They can simultaneously jam radars of various types and from various directions, offering the advantage of high cost-effectiveness in jamming. Therefore, they are widely used in electronic warfare, radar reconnaissance and early warning, and other operational environments. Simultaneously, as RCS enhancers, calibration targets, or target objects, corner reflectors are widely used in radar remote sensing, maritime search and rescue, indoor and outdoor target characteristic testing, and simulated targets.

[0003] In related technologies, the three reflective surfaces of corner reflectors are rigidly connected. After the corner reflector is manufactured, because the three triangular reflective surfaces are perpendicular to each other, the reflector occupies a large space, making it inconvenient to store and transport. Especially when corner reflectors are used as mobile radar jammers or countermeasures devices, they need to be moved and quickly retrieved and deployed along with the protected target. However, the fixed structure of corner reflectors makes them very inconvenient to carry and transport, severely restricting their application.

[0004] Therefore, in order to address the above shortcomings, there is an urgent need for a corner reflector that is easy to store and transport. Summary of the Invention

[0005] This invention provides an electrically controlled foldable corner reflector, which facilitates storage and transportation.

[0006] This invention provides an electrically controlled foldable corner reflector, comprising a first reflector, a second reflector, and a third reflector in the shape of a right triangle. Each of the first, second, and third reflectors includes a first right-angled side and a second right-angled side. The first right-angled side of the first reflector is hinged to the first right-angled side of the second reflector, and the second right-angled side of the second reflector is hinged to the first right-angled side of the third reflector. The second right-angled side of the third reflector is detachably connected to the second right-angled side of the first reflector.

[0007] When it is necessary to fold the corner reflector, the connection between the first reflector and the third reflector is disconnected, the third reflector is folded toward the second reflector, and then the folded second reflector and the third reflector are folded toward the first reflector, so that the first reflector, the second reflector and the third reflector are folded into three layers;

[0008] The bottom of the first reflector is connected to a support platform, which is used to adjust the height of the corner reflector.

[0009] In one possible design, the second right-angled side of the first reflector is provided with a limiting seat, the limiting seat is provided with a slot for inserting the third reflector, the portion of the third reflector embedded in the slot is provided with a through hole, and the limiting seat is also provided with a spring plunger, the spring plunger including a pin;

[0010] When it is necessary to connect the first reflector and the third reflector, pull out the pin to insert the third reflector into the slot, and release the pin to allow it to pass through the through hole in the slot. When it is necessary to separate the first reflector and the third reflector, pull out the pin to remove the third reflector from the slot.

[0011] In one possible design, the support platform includes a plate and multiple legs, the bottom of the first reflector is connected to the plate, the plate and the legs are connected by a pivot pin, and the legs rotate along the pivot pin to make the legs contact the bottom of the plate.

[0012] In one possible design, the shaft pin is provided with a detachable ball head locking pin, the ball head locking pin is installed to prevent the support leg from rotating, the support leg is provided with a limiting ear, the limiting ear is provided with a limiting hole, the bottom of the plate is provided with a limiting groove that matches the limiting ear, and the plate is provided with an insertion hole that communicates with the limiting groove.

[0013] When the support platform needs to be folded, remove the ball head locking pin, fold the support leg so that the limiting ear is inserted into the limiting groove, and insert the removed ball head locking pin into the insertion hole and the limiting hole to fix the support leg to the bottom of the plate.

[0014] In one possible design, the plate is provided with a baffle, which is hinged to the plate. The baffle is rotated to cover the opening of the corner reflector, which is an unclosed surface of the tetrahedron formed by the first reflector, the second reflector, and the third reflector.

[0015] In one possible design, the baffle is connected to the plate body by a torsion spring hinge, an electromagnet is connected to the baffle, an adsorption element is provided on the outside of the corner reflector, and the magnetic force between the electromagnet and the adsorption element is greater than the elastic force of the torsion spring hinge.

[0016] When it is necessary to cover the opening, the electromagnet is de-energized to make it magnetic, and the baffle is rotated to cover the opening by overcoming the elastic force of the torsion spring hinge. The electromagnet and the adsorption member are connected by magnetic force to keep the baffle in the state of covering the opening. When it is necessary to open the opening, the electromagnet is energized to demagnetize it, and the baffle is opened by the elastic force of the torsion spring hinge to open the opening.

[0017] In one possible design, the baffle is provided with two connecting plates at the end away from the plate body, each connecting plate is provided with a flexible strip at the end away from the plate body, and each flexible strip is provided with an electromagnet at the end away from the connecting plate.

[0018] In one possible design, a strap is provided at the bottom of the plate, a male buckle is provided at the end of the strap away from the plate, and a female buckle is provided on the baffle.

[0019] After folding the corner reflector, the baffle is rotated to overlap the corner reflector by overcoming the elastic force of the torsion spring hinge, and the male and female snap fasteners are joined to fix the baffle on the corner reflector.

[0020] In one possible design, the plate is an isosceles right triangle with a size larger than the first reflector, and the right-angle vertex of the plate and the right-angle vertex of the first reflector are located on the same vertical line. The torsion spring hinge is located at the end of the plate near the hypotenuse.

[0021] In one possible design, the baffle is a triangle with the same shape as the opening.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] In this embodiment, the first and second reflective plates are hinged together, the second and third reflective plates are hinged together, the first and third reflective plates are detachably connected, and the corner reflector is tetrahedral in shape. The three faces of the tetrahedron are composed of three reflective surfaces, and the face of the tetrahedron without a reflective surface is the opening of the corner reflector. Electromagnetic waves enter the tetrahedron formed by the corner reflector through the opening, and the electromagnetic waves entering the corner reflector are reflected by the reflective surfaces and then emitted through the opening.

[0024] When a foldable corner reflector is needed, first disconnect the connection between the first and third reflectors, fold the third reflector towards the second reflector, and then fold the folded second and third reflectors towards the first reflector, so that the first, second, and third reflectors are folded into three layers. The folded corner reflector is small in size, which is beneficial for storage and transportation. Attached Figure Description

[0062] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0063] In the description of the embodiments of the present invention, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or stated, the term "multiple" refers to two or more; the terms "connected," "fixed," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0064] In this specification, it should be understood that the directional terms such as "upper" and "lower" used in the description of the embodiments of the present invention are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of the present invention. Furthermore, in the context, it should also be understood that when it is mentioned that one element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0065] like Figure 1 , Figure 2 As shown, this embodiment of the invention provides an electrically controlled foldable corner reflector, including a first reflector 1, a second reflector 2, and a third reflector 3 in the shape of a right triangle. The first reflector 1, the second reflector 2, and the third reflector 3 each include a first right-angled side and a second right-angled side. The first right-angled side of the first reflector 1 is hinged to the first right-angled side of the second reflector 2, and the second right-angled side of the second reflector 2 is hinged to the first right-angled side of the third reflector 3. The second right-angled side of the third reflector 3 is detachably connected to the second right-angled side of the first reflector 1.

[0066] When a folded corner reflector is needed, the connection between the first reflector 1 and the third reflector 3 is disconnected, the third reflector 3 is folded toward the second reflector 2, and then the folded second reflector 2 and the third reflector 3 are folded toward the first reflector 1, so that the first reflector 1, the second reflector 2 and the third reflector 3 are folded into three layers.

[0067] The bottom of the first reflector 1 is connected to a support platform, which is used to adjust the height of the corner reflector.

[0068] In this embodiment, the first reflector 1 and the second reflector 2 are hinged together, the second reflector 2 and the third reflector 3 are hinged together, the first reflector 1 and the third reflector 3 are detachably connected, and the corner reflector is tetrahedral in shape. The three faces of the tetrahedron are composed of three reflective surfaces, and the face of the tetrahedron without reflective surfaces is the opening of the corner reflector. Electromagnetic waves enter the tetrahedron formed by the corner reflector through the opening, and the electromagnetic waves entering the corner reflector are reflected by the reflective surfaces and then emitted through the opening.

[0069] When a folded corner reflector is needed, first disconnect the connection between the first reflector 1 and the third reflector 3. Fold the third reflector 3 towards the second reflector 2. Then, fold the folded second reflector 2 and third reflector 3 towards the first reflector 1, so that the first reflector 1, second reflector 2, and third reflector 3 are folded into three layers. Please refer to... Figure 4 , Figure 5 The folded corner reflector is small in size, which is beneficial for storage and transportation.

[0070] It should be noted that the hinges between the first reflector 1, the second reflector 2, and the third reflector 3 can be achieved using hinges.

[0071] In some embodiments of the present invention, a limiting seat 4 is provided on the second right-angled side of the first reflector 1, and a slot is provided on the limiting seat 4 for inserting the third reflector 3. The portion of the third reflector 3 that is embedded in the slot is provided with a through hole. A spring plunger 5 is also provided on the limiting seat 4, and the spring plunger 5 includes a pin.

[0072] When it is necessary to connect the first reflector 1 and the third reflector 3, pull out the pin to insert the third reflector 3 into the slot, and release the pin to allow it to pass through the through hole in the slot. When it is necessary to separate the first reflector 1 and the third reflector 3, pull out the pin to remove the third reflector 3 from the slot.

[0073] In this embodiment, a limiting seat 4 is provided on the second right-angled side of the first reflector 1. The limiting seat 4 has a slot, into which the third reflector 3 can be inserted. To make the third reflector 3 more securely inserted in the slot, a spring plunger 5 is provided on the limiting seat 4. The spring plunger 5 includes a pin, which passes through the limiting seat 4 and enters the slot. A spring is provided between the pin and the spring plunger 5, keeping the pin inserted into the slot. When it is necessary to connect the first reflector 1 and the third reflector 3, the pin is pulled out against the spring force, and the third reflector 3 is inserted into the slot. The portion of the third reflector 3 inserted into the slot has a through hole that matches the pin. After the third reflector 3 is inserted into the slot, the pin is released, and the pin inserts into the through hole, thus fixing the third reflector 3 in the slot.

[0074] It should be noted that the width of the card slot can be the same as the thickness of the third reflector 3. With this setting, the third reflector 3 inserted into the card slot will not move relative to its thickness. The outer diameter of the pin can be equal to the diameter of the through hole. With this setting, the third reflector 3 passed through by the pin in the card slot will not move relative to the depth of the card slot, and the third reflector 3 will not move relative to the length of the card slot.

[0075] In some embodiments of the present invention, the first reflector 1, the second reflector 2, and the third reflector 3 each include a reflective surface for reflecting electromagnetic waves and a mounting surface for mounting hinges. The mounting surfaces of the first reflector 1, the second reflector 2, and the third reflector 3 are all provided with reinforcing plates, which are used to increase the strength, rigidity, and surface accuracy of the first reflector 1, the second reflector 2, and the third reflector 3.

[0076] In this embodiment, the reflective surface is used to reflect electromagnetic waves. To maintain the accuracy of the corner reflector, the reflective surface needs to be flat. The mounting surface does not reflect electromagnetic waves; therefore, a reinforcing plate and a hinge can be installed on the mounting surface. The hinge is used to achieve the hinge between the first reflector 1 and the second reflector 2, as well as the hinge between the second reflector 2 and the third reflector 3. Installing a reinforcing plate on the mounting surface can increase the strength, rigidity, and surface accuracy of the first reflector 1, the second reflector 2, and the third reflector 3, enabling the corner reflector to adapt to harsher operating environments and preventing deformation or breakage during transportation or storage.

[0077] In some embodiments of the present invention, a reinforcing plate is disposed at the edge of the mounting surface.

[0078] In this embodiment, a reinforcing plate is set at the edge of the mounting surface to form a frame structure. This arrangement increases the strength, rigidity, and surface accuracy of the corner reflector, while also saving materials, reducing the weight of the corner reflector, and increasing its aesthetics.

[0079] In some embodiments of the present invention, the first reflector 1 and the second reflector 2 are hinged by a first hinge 21, and the second reflector 2 and the third reflector 3 are hinged by a second hinge 22. The first hinge 21 includes a first part 211, a second part 212, a third part 213, and a fourth part 214 connected in sequence. The plane containing the first part 211 is perpendicular to the plane containing the second part 212, and the plane containing the third part 213 is perpendicular to the plane containing the fourth part 214. The second part 212 and the third part 213 are provided with shaft holes for the rotating shaft. The second part 212 and the third part 213 are connected through the shaft hole. The first part 211 is attached to the reinforcing plate of the first reflector 1. The second part 212 is parallel to the side of the first reflector 1 and the reinforcing plate. The third part 213 is parallel to the side of the second reflector 2 and the reinforcing plate. The fourth part 214 is attached to the reinforcing plate of the second reflector 2. The second hinge 22 includes a first leaf piece and a second leaf piece 222. The first leaf piece 221 and the second leaf piece 222 are provided with shaft holes. The rotating shaft passes through the shaft hole to connect the first leaf piece 221 and the second leaf piece 222.

[0080] It should be noted that the second part 212 is parallel to the side of the first reflector 1 and the reinforcing plate, and the third part 213 is parallel to the side of the second reflector 2 and the reinforcing plate. The second part 212 and the third part 213 do not contact the reflectors. This arrangement can prevent the reflectors from interfering with each other during the folding process.

[0081] Please refer to Figure 6 The first part 211 and the second part 212 are perpendicular to each other, and the third part 213 and the fourth part 214 are perpendicular to each other. The second part 212 and the third part 213 are rotatably connected. With this configuration, after the corner reflector is folded, the second part 212 and the third part 213 increase the space thickness between the first part 211 and the fourth part 214. This thickness space is used to accommodate the folded first reflector 1 and the second reflector 2. Please refer to... Figure 7 The first and second leaf pieces 221 and 222 of the second hinge 22 are both flat leaf pieces. With this arrangement, after the corner reflector is folded, the first and second leaf pieces 221 and 222 of the second hinge 22 are folded between the second reflector 2 and the third reflector 3.

[0082] In some embodiments of the present invention, the support platform includes a plate 6 and a plurality of legs 7. The bottom of the first reflector 1 is connected to the plate 6, and the plate 6 and the legs 7 are connected by a pivot pin 9. The legs 7 rotate along the pivot pin 9 so that the legs 7 are in contact with the bottom of the plate 6.

[0083] In this embodiment, a support platform is provided at the bottom of the corner reflector to increase the height of the corner reflector. The support platform includes a plate 6 and multiple legs 7. The plate 6 and the legs 7 are connected by a pivot pin 9. Specifically, the legs 7 include two front legs 7 and one rear leg 7. The plate 6 is provided with two front mounting ears and one rear mounting ear. The two front legs 7 are connected to the front mounting ears by the pivot pin 9, and the one rear leg 7 is connected to the rear mounting ear by the pivot pin 9. The legs 7 can rotate around the pivot pin 9. Rotating the legs 7 around the pivot pin 9 to fold them with the plate 6 can save space.

[0084] In some embodiments of the present invention, the shaft pin 9 is provided with a detachable ball head locking pin 8, the ball head locking pin 8 is installed to prevent the support leg 7 from rotating, the support leg 7 is provided with a limiting ear 10, the limiting ear 10 is provided with a limiting hole, the bottom of the plate body 6 is provided with a limiting groove that matches the limiting ear 10, and the plate body 6 is provided with an insertion hole 11 that communicates with the limiting groove.

[0085] When the folding support platform is required, remove the ball head locking pin 8, fold the support leg 7 so that the limiting ear 10 is inserted into the limiting groove, and insert the removed ball head locking pin 8 into the insertion hole 11 and the limiting hole to fix the support leg 7 to the bottom of the plate 6.

[0086] In this embodiment, when the corner reflector is working, in order to prevent the support leg 7 from rotating and causing the support platform to become unstable, the ball head locking pin 8 is inserted into the connection of the shaft pin 9 to fix the support leg 7 and the platform, so that the support leg 7 and the platform will not rotate; when it is necessary to store or transfer the corner reflector, the ball head locking pin 8 is pulled out, the support leg 7 is rotated so that it overlaps the bottom of the plate body 6, and the removed ball head locking pin 8 is inserted into the insertion hole 11 and the limiting hole located in the limiting groove, so that the support leg 7 is fixed to the bottom of the plate body 6.

[0087] In some embodiments of the present invention, the plate 6 is provided with a baffle 12, which is hinged to the plate 6. The baffle 12 is rotated to cover the opening of the corner reflector. The opening is the unclosed surface of the tetrahedron formed by the first reflector 1, the second reflector 2 and the third reflector 3.

[0088] In this embodiment, after the corner reflector is installed and is not required to work, the baffle 12 can be rotated to block the opening of the corner reflector so that the corner reflector does not work. When the corner reflector needs to work, the baffle 12 can be rotated to open the opening. Compared with the solution of adding a shielding cover in the prior art, the operation is simple, time-saving and efficient.

[0089] like Figure 2 , Figure 3 As shown, in some embodiments of the present invention, the baffle 12 is connected to the plate 6 by a torsion spring hinge 13, an electromagnet 14 is connected to the baffle 12, and an adsorption element 15 is provided on the outside of the corner reflector. The magnetic force between the electromagnet 14 and the adsorption element 15 is greater than the elastic force of the torsion spring hinge 13.

[0090] When it is necessary to cover the opening, the electromagnet 14 is de-energized to make it magnetic, and the baffle 12 is rotated to cover the opening by overcoming the elastic force of the torsion spring hinge 13. The electromagnet 14 and the adsorption member 15 are connected by magnetic force to keep the baffle 12 in the state of covering the opening. When it is necessary to open the opening, the electromagnet 14 is energized to demagnetize it, and the baffle 12 is opened by the elastic force of the torsion spring hinge 13.

[0091] In this embodiment, the baffle 12 is connected to the plate 6 via a torsion spring hinge 13. The torsion spring hinge 13 provides elasticity to keep the baffle 12 away from the opening. An electromagnet 14 is connected to the baffle 12, and an adsorption element 15 is provided on the outside of the corner reflector. Overcoming the elasticity of the torsion spring hinge 13, the baffle 12 is rotated to a position where the opening is closed. The electromagnet 14 is magnetically controlled by the circuit. Connecting the electromagnet 14 and the adsorption element 15 keeps the baffle 12 in a closed state. When it is necessary to open the opening, the baffle 12 can be automatically opened by demagnetizing the electromagnet 14. With this configuration, multiple closed corner reflectors can be opened simultaneously by demagnetizing the electromagnet 14.

[0092] It should be noted that the electromagnet 14 can be either an electromagnet 14 that is demagnetized by being energized or an electromagnet 14 that is demagnetized by being ...

[0093] In some embodiments of the present invention, two connecting plates 16 are provided at the end of the baffle 12 away from the plate body 6, and a flexible strip 17 is provided at the end of each connecting plate 16 away from the plate body 6, and an electromagnet 14 is provided at the end of each flexible strip 17 away from the connecting plate 16.

[0094] In this embodiment, two connecting plates 16 are provided at the end of the baffle 12 away from the plate body 6. The two connecting plates 16 are respectively located on both sides of the narrow end of the plate body 6. A flexible strip 17 is provided on the part of the connecting plate 16 that extends beyond the baffle 12. The flexible strip 17 is connected to the electromagnet 14. The combination of the connecting plate 16 and the flexible strip 17 facilitates the connection between the electromagnet 14 and the adsorption member 15.

[0095] In some embodiments of the present invention, a strap 18 is provided at the bottom of the plate 6, a male buckle 19 is provided at the end of the strap 18 away from the plate 6, and a female buckle is provided on the baffle 12.

[0096] After folding the corner reflector, the baffle 12 is rotated to overlap the corner reflector by overcoming the elastic force of the torsion spring hinge 13. The male buckle 19 and the female buckle 20 are then joined to fix the baffle 12 on the corner reflector.

[0097] In this embodiment, pressing the baffle 12 onto the folded corner reflector and locking the male buckle 19 onto the female buckle 20 can bind the baffle 12 to the corner reflector. The baffle 12 can be opened by separating the male buckle 19 and the female buckle 20.

[0098] In some embodiments of the present invention, the plate 6 is an isosceles right triangle with a size larger than that of the first reflector 1, and the right-angle vertex of the plate 6 and the right-angle vertex of the first reflector 1 are located on the same vertical line. The torsion spring hinge 13 is provided at one end of the plate 6 near the hypotenuse.

[0099] In this embodiment, the plate 6 is a slightly larger triangle similar to the first reflector 1, which saves space and allows for the installation of torsion spring hinges 13 on the portion of the plate 6 that extends beyond the first reflector 1.

[0100] In some embodiments of the present invention, the baffle 12 is a triangle with the same shape as the opening.

[0101] In this embodiment, the baffle 12 is a triangle with the same shape as the opening, which can save materials and space while blocking the opening.

[0102] Example:

[0103] When the corner reflector is in operation, remove the folded corner reflector from the packaging box and move it to the desired placement and installation location. First, pull out the three ball-head locking pins 8 on the plate 6 that lock the two front legs 7 and one rear leg 7, unfold the three legs 7 to the working position, and insert the ball-head locking pins 8 into the limiting holes on the legs 7 respectively to keep the legs 7 locked. Then, squeeze the female latches 20 installed on both sides of the baffle 12 by hand to make the male latches 19 pop out from the female latches 20, unfolding the baffle 12. Next, unfold the second reflector 2 relative to the first reflector 1, while simultaneously rotating the third reflector 3 around the hinge to unfold the third reflector 3 relative to the second reflector 2. After the three reflective surfaces are fully deployed, place one side of the third reflector 3 into the slot of the limiting seat 4, and pull out the pin on the limiting spring plunger 5 so that one side of the third reflector 3 is completely placed in the slot of the limiting seat 4. At this time, the pin on the limiting spring plunger 5 will insert into the through hole on the third reflector 3 under the action of the spring force, locking the positions of the three reflective surfaces of the corner reflector, which are perpendicular to each other and fully deployed. Finally, let the baffle 12 cover the opening of the reflector, rotate the baffle 12 to the covered position, and make the electromagnet 14 engage with the adsorption components on the reflective surface of the corner reflector. At this time, the magnetic force generated by the two electromagnets 14 and the two adsorption components is greater than the elastic force generated by the two torsion spring hinges 13, and the baffle 12 remains in the covered state. In this way, the deployed corner reflector will always be in the covered state, which can prevent it from being detected by the enemy.

[0104] When the protected equipment encounters an alarm or threat, the electromagnet 14 on the reflector can be energized remotely. Within a very short time, the electromagnet 14 is demagnetized, and the baffle 12 opens rapidly under the elastic force of the torsion spring hinge 13, activating the corner reflector. When radar waves from an enemy weapon illuminate the corner reflector, the corner reflector forms a large radar cross-section, and the combination of multiple corner reflectors can create certain simulated characteristics, guiding the enemy weapon towards the corner reflector, thereby protecting high-value targets.

[0105] This intellectual property design presents a foldable corner reflector with an electrically controlled baffle 12. By designing the three reflective surfaces of a traditional corner reflector as rotatable and foldable surfaces, and adding an electrically controlled folding structure, the reflector can be quickly converted from a folded to a fully extended state when deployed. Simultaneously, the electrically controlled baffle 12 reduces the probability of the corner reflector being detected by the enemy in its non-operational state. When the corner reflector is in use, it can be quickly switched to an operational state with a single button operation, thus protecting high-value targets and equipment. It can also be quickly folded and retrieved when needed.
