Description

Technical Field

[0001] The present invention relates to the technical field of tank protection, and in particular to a lightweight tank protection net for preventing drones from attaching bombs to the net. Background Art

[0002] With the widespread adoption of drone technology, especially small reconnaissance and strike drones, the low-altitude threats faced by tanks and armored vehicles have increased significantly. Drones can fly close to tanks and carry small explosives (such as C4 charges and prefabricated fragmentation rounds) to carry out precision attacks.

[0003] Existing tank protection measures have the following defects:

[0004] 1. Fixed armor: heavy (additional armor is usually > 200kg / ㎡), affecting tank mobility;

[0005] 2. Rigid protective net: Most of them are metal woven nets. Although they can intercept fragments, they have poor explosion resistance (explosion shock waves can easily cause the net to tear), and they cannot be folded and stored, so they take up a lot of space.

[0006] 3. Low deployment efficiency: Traditional protective devices require manual assistance to deploy, which takes more than 30 seconds and cannot cope with sudden attacks.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0030] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figure 1 : A lightweight tank protection net to prevent drones from attaching bombs to destroy the tank, the lightweight tank protection net to prevent drones from attaching bombs to destroy the tank comprises: a tank body 1 and a foldable protection net mechanism 2, the foldable protection net mechanism 2 is covered on the tank body 1; wherein, when the foldable protection net mechanism 2 is in a folded state, it can be stored tightly against the side of the tank body 1 away from its turret; when the foldable protection net mechanism 2 is in an unfolded state, it can be covered above the tank body 1.

[0032] Through this design, the present application can unfold the protective net when it is needed to protect the tank, and can store it tightly against the tank body 1 when it is not needed, thereby reducing the volume of the tank and improving the tank's maneuverability. The material of the protective net is preferably lightweight and high-strength material, such as ultra-high molecular weight polyethylene fiber, Kevlar fiber or carbon fiber composite material, which reduces its own weight while ensuring impact resistance.

[0033] Reference Figure 1 : The lightweight anti-UAV bomb-destroying tank protection net also includes: a first slide rail 3 and a first drive component 4. The first slide rails 3 are provided on the opposite sides of the tank body 1, which can be close to or away from the tank body 1 through the first drive component 4. The foldable protection net mechanism 2 can be folded on the first slide rails 3 on the opposite sides.

[0034] The general protective net of this application will have a certain distance from the tank body 1 to ensure its protective function, but this design makes it impossible for the protective net to be close to the tank body 1 when it is folded and stored; this application can drive each first slide rail 3 to move close to the tank body 1 through the first drive component 4, so that the protective net is close to the tank body 1, thereby reducing the width of the protective net after contraction, reducing the volume of the tank, and improving the maneuverability of the tank.

[0035] Reference Figure 3 : The first drive assembly 4 includes: a first linear motor 401 and a first connecting rod 402. Several first connecting rods 402 are arranged at intervals on the inner side of each first slide rail 3. One end of the first connecting rod 402 is hinged to the inner side of the first slide rail 3, and the other end is hinged to one side of the tank body 1. The output end of the first linear motor 401 is hinged to the inner side of the first slide rail 3, and its other end is hinged to one side of the tank body 1.

[0036] In the present application, the first linear motor 401 is tilted relative to the first connecting rod 402 to prevent the first linear motor 401 from getting stuck, which would cause the first slide rail 3 to be unable to approach or move away from the tank body 1.

[0037] Reference Figure 2 : The foldable protective net mechanism 2 includes: a first moving rod 201, a telescopic component 202, an elastic protective net and a second drive component 203. The first slide rail 3 is vertically arranged with several first moving rods 201 at intervals along its length direction. The first moving rod 201 away from the turret end of the tank body 1 is fixed, and adjacent first moving rods 201 are connected by a telescopic component 202. The opposite sides of the elastic protective net are respectively fixed on the corresponding first moving rods 201. The second drive component 203 is arranged on the tank body 1 to drive the first moving rod 201 close to the turret end of the tank body 1 to move back and forth.

[0038] When unfolded, the elastic protective net of the present application will be stretched tight on the tank body 1 to ensure its protective effect; when folded, the elastic protective net will cooperate with the first drive assembly 4 and the first slide rail 3, so that the elastic protective net is tightly attached to the tank body 1, thereby greatly reducing the volume of the tank body 1 after the elastic protective net is folded, and improving the tank's maneuverability.

[0039] Reference Figure 3 and Figure 4 The telescopic assembly 202 includes a first connecting rod 402 and a second connecting rod 20201. The first connecting rod 402 and the second connecting rod 20201 are assembled together in a scissor-type manner, and their four relative ends are respectively fixed on adjacent first moving rods 201.

[0040] In the present application, the first connecting rod 402 and the second connecting rod 20201 are connected by a hinge shaft in the middle to form a rotatable "X"-shaped structure. When the second drive assembly 203 pushes the first movable rod 201 near one end of the turret of the tank body 1 to move, the scissors-type unit realizes the length change through the rotation of the hinge point, thereby realizing the telescopic folding of the protective net in the length direction.

[0041] Reference Figure 3 and Figure 4 : The second drive assembly 203 includes: a first rotating motor 20301, a first synchronous wheel 20302, a second synchronous wheel 20303 and a synchronous belt 20304. The first rotating motor 20301 is arranged on one side of the tank body 1, and the output end thereof is coaxially provided with the first synchronous wheel 20302. The second synchronous wheel 20303 is rotatably arranged on the side of the tank body 1 away from the first synchronous wheel 20302. The opposite ends of the synchronous belt 20304 are respectively sleeved on the first synchronous wheel 20302 and the second synchronous wheel 20303. The first moving rod 201 close to one end of the tank body 1 is fixed on the upper side or the lower side of the synchronous belt 20304.

[0042] This application starts the first rotating motor 20301 to drive the first synchronous wheel 20302 to rotate, and then drives the second synchronous wheel 20303 to rotate through the synchronous belt 20304. During the rotation process, the synchronous belt 20304 will drive the first moving rod 201 to move back and forth along the length direction of the first slide rail 3, thereby realizing the folding and straightening of the elastic protective net.

[0043] Reference Figure 2 : The foldable protective net mechanism 2 also includes a first support assembly 204 arranged above each first moving rod 201.

[0044] The present application supports the elastic protective net through the first support component 204. The first support component 204 is fixed above the first movable rod 201, and directly applies an upward support force to the upper surface of the elastic protective net to offset the sagging tendency caused by the net's own weight and external impact, ensuring that the protective net always maintains a flat, non-loose coverage state; the first support component 204 serves as the "skeleton" of the net surface, and can transmit the instantaneous impact force of the impact point to the adjacent first movable rod 201 and telescopic component 202 through its own structure to avoid stress concentration in a single area. The first support component 204 can be made of elastic materials such as high-toughness nylon or lightweight alloy, which can form a "double elastic buffer" with the elastic protective net, prolonging the absorption time of impact energy, reducing the instantaneous deformation of the net surface, thereby delaying material fatigue and improving the protective effect.

[0045] Reference Figure 3 and Figure 4 : The first support assembly 204 includes: a first frame 20401 and a fourth connecting rod 20402. The first frame 20401 is in an "L" shape. A first frame 20401 is vertically arranged on the upper end of each first movable rod 201. One end of the fourth connecting rod 20402 is hinged to the outer end of the first frame 20401, and the other end is hinged to another fourth connecting rod 20402.

[0046] In the first support assembly 204 of the present application, when the first slide rail 3 approaches the tank body 1, the multiple hinged fourth links 20402 can compress or increase the length of the entire first support assembly 204 to prevent the first support assembly 204 from being unable to move and interfering with the first slide rail 3 approaching or moving away from the tank body 1.

[0047] Reference Figure 3 and Figure 4 : The second support assembly 205 also includes: a second frame 20501 and a fifth connecting rod 20502, one end of the second frame 20501 is hinged to the side of the first movable rod 201 away from one end of the turret of the tank body 1, one end of the fifth connecting rod 20502 is hinged to the outer end of the second frame 20501, and the other end is hinged to another fifth connecting rod 20502 relative to it.

[0048] Through this design, the present application can extend the coverage range of the elastic protective net to further prevent the tank from being damaged by drone bombs.

[0049] Reference Figure 3 : The tank body 1 is also provided with a linear guide rail 5 for guiding the first support assembly 204 and the second support assembly 205 to move back and forth along the length direction of the first slide rail 3.

[0050] The present application specifically guides the first support assembly 204 and the second support assembly 205 by passing a relatively thick and hard steel wire through the hinges of the two relative fourth connecting rods 20402 or the fifth connecting rods 20502. The elastic protective net is made of lightweight carbon fiber material to prevent the steel wire from being compressed and deformed. This design prevents the first support assembly 204 and the second support assembly 205 from interfering with each other when compressing their own lengths, resulting in their inability to return to the expanded state. The first frame 20401 and the second frame 20501 are both telescopically assembled at the upper end of the first movable rod 201.

[0051] Reference Figure 3 : The tank body 1 is also horizontally provided with a support frame 206 for fixing the protective net on the side away from its turret. The support frame 206 is "L"-shaped and is slidably assembled with one end close to the first slide rail 3.

[0052] By fixing the tail end of the elastic protective net on the support frame 206, the covering range of the elastic protective net can be further extended to further prevent the tank from being damaged by drone bombs.

[0053] Reference Figure 1 : Foldable folding frame assemblies 6 are respectively provided on the opposite sides of the tank body 1 above its tracks.

[0054] The folding frame assembly 6 is in a side "V" shape when unfolded and in a "1" shape when folded. It is achieved by manually adjusting two damping hinged folding frames to prevent drones with bombs from damaging tank tracks; the tank tracks are not drawn in the attached drawings.

[0055] The device provided by the present invention has this design. When the protective net is needed, it can be unfolded to protect the tank. When the protective net is not needed, it can be stored tightly against the tank body, reducing the volume of the tank and improving the tank's maneuverability. The material of the protective net is preferably lightweight and high-strength material, such as ultra-high molecular weight polyethylene fiber, Kevlar fiber or carbon fiber composite material, which reduces its own weight while ensuring impact resistance.

[0056] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.

[0057] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0058] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
