Description

Technical Field

[0001] This utility model belongs to the field of drone capture technology, and in particular relates to a telescopic drone capture device. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and onboard program control devices, or operated fully or intermittently by onboard computers. Compared with manned aircraft, UAVs are often more suitable for dangerous missions.

[0003] In ordinary living spaces, the use of drones by criminals to steal privacy can cause significant social harm. Furthermore, in modern warfare, drones pose a serious threat and cause serious injury to infantry. Methods to counter drones generally include radio jamming or physical destruction; netting is an effective option for physical destruction. For example, the drone catcher disclosed in announcement number CN112902757B, which improves the capture effect, consists of a launch gun head, a head assembly, and a capture assembly. The catcher relies on a pneumatic launch gun head for firing, resulting in a complex structure and high manufacturing and operating costs. Therefore, to address these issues, a simple and easy-to-operate telescopic drone capture device is provided. Utility Model Content

[0004] This utility model provides a telescopic drone capture device, comprising a shell, a telescopic component, and a capture component. The telescopic component is formed by multiple interconnected sleeves. The capture component includes an elastic connecting rod and an elastic capture net. A compression spring is located inside the shell, connecting the bottommost sleeve to the bottom of the shell. Blocking elements are installed on both sides of the front end of the shell via insertion limiting holes, which act as blocking elements after the telescopic component and the capture component retract into the shell. In use, the shell is held with the front opening facing the drone. By pulling the blocking elements, the bottommost sleeve is pushed forward along the opening by the spring, and the bottommost sleeve is... After the first limiting structure blocks the flow, the handheld casing is used to throw out the multiple interlocking sleeves. Simultaneously, the elastic connecting rod at the front end and the elastic capture net are also thrown out from the front end sleeve. The elastic capture net opens from a contracted and coiled state to form a net. By waving the handheld casing, the elastic capture net binds the approaching drone. The drone's propellers lose balance and control due to the net's adhesion, thus capturing the drone. This capture device has a compact and simple structure, is easy to carry and use, has no complex structure, has low manufacturing and usage costs, and can be recycled and reused. In summary, it solves the problems in the background technology.

Detailed Implementation

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0044] In the description of this utility model, it should be understood that the terms "inner", "front end", "bottom end", "bottom", "front end", "top", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0046] Please see Figures 1-6 As shown, a telescopic drone capture device of the present invention includes a shell 1, a telescopic component installed inside the shell 1, and a capture component disposed at the front end of the telescopic component; in this embodiment, the shell 1 adopts a sleeve structure with a solid bottom.

[0047] The telescopic component is made of multiple sleeves 2 connected together, with each sleeve 2 arranged coaxially, and the diameter gradually decreasing from the bottom end to the front end.

[0048] The bottom of the sleeve 2 at the bottom is provided with a base plate 204. A compression spring 103 is connected between the base plate 204 and the bottom of the outer shell 1. The compression spring 103 is provided so that after the blocking member 3 is removed, the bottom sleeve of the telescopic component can quickly extend from the front end of the outer shell 1, thereby facilitating the swinging action and ultimately allowing the telescopic component to be thrown out to its longest state. Of course, it is also feasible not to provide the compression spring 103, which is also within the protection scope of this technical solution. In use, the telescopic component is thrown out by swinging, and since the elastic capture net 4 is elastic, it can be popped out from the front sleeve 2.

[0049] Symmetrical insertion and limiting holes 101 are provided on both sides of the front end of the outer shell 1. A blocking member 3 is inserted into each insertion and limiting hole 101 to block and limit the movement of the telescopic and capturing components after they retract into the outer shell 1. The blocking member 3, located in the insertion and limiting hole 101, allows the sleeve 2, elastic connecting rod 401, and elastic capturing net 4 to be stably accommodated within the outer shell 1. The blocking member 3 can be a baffle structure that can be removed, or a circular baffle that can be rotated at one end. When needed, the baffle-type blocking member 3 can be removed directly, or the circular baffle-type blocking member 3 can be rotated for use. Of course, other forms of solutions that can achieve the blocking requirements of this scenario and produce the same technical effect are also within the scope of protection of this solution.

[0050] The capturing component includes an elastic connecting rod 401 installed in the frontmost sleeve 2 and an elastic capturing net 4 located at the front end of the elastic connecting rod 401; the elastic capturing net 4 is housed together with the elastic connecting rod 401 in the frontmost sleeve 2 in the retracted state.

[0051] The outer shell 1 has an open front end and a solid bottom at the rear end, forming a space between the open end and the solid bottom to accommodate the telescopic component and the capturing component.

[0052] Among them, the bottommost sleeve 2 is provided with a first limiting structure between it and the outer shell 1, the two adjacent sleeves 2 are provided with a second limiting structure, and the elastic connecting rod 401 is provided with a third limiting structure between it and the frontmost sleeve 2.

[0053] The first limiting structure includes a first limiting groove 104 radially arranged on the inner sidewall of the outer shell 1, a first limiting block 202 disposed on the lower sidewall of the sleeve 2 at the bottom end and slidingly matching the first limiting groove 104, and a first limiting retaining ring 102 disposed on the top of the outer shell 1 to block the first limiting block 202. In this embodiment, the first limiting groove 104 and the first limiting block 202 are arranged in four sets at equal intervals around the perimeter, which increases stability. Of course, any other number of these blocks can ensure the limiting and guiding functions and are all within the protection scope of this technical solution.

[0054] The second limiting structure includes a second limiting groove 201 radially disposed on the inner side wall of the rear sleeve 2, a second limiting retaining ring 203 at the top of the rear sleeve 2, and a second limiting block 205 on the lower side wall of the front sleeve 2 that cooperates with the second limiting retaining ring 203. The second limiting block 205 slides and matches the second limiting groove 201. In this embodiment, four sets of the second limiting groove 201 and the second limiting block 205 are arranged around the sleeve at equal intervals to increase stability. Of course, any other number of these blocks can ensure the limiting and guiding functions and are within the protection scope of this technical solution.

[0055] The third limiting structure includes a connecting post 402 located at the bottom of the elastic connecting rod 401, and a third limiting block 403 located on the lower side wall of the connecting post 402, which cooperates with the second limiting retaining ring 203 at the top of the foremost sleeve 2. The third limiting block 403 slides in cooperation with the second limiting groove 201 inside the foremost sleeve 2. In this embodiment, the number and position of the third limiting block 403 and the second limiting groove 201 correspond to each other, which increases stability. Of course, setting other numbers can ensure the limiting and guiding functions, and all of these are within the protection scope of this technical solution.

[0056] Among them, the elastic capture net 4 is made of carbon rope weaving, the sleeve 2 is made of carbon tube, and the elastic connecting rod 401 is made of carbon rod; the elastic capture net 4 is surrounded by a frame made of elastic carbon rod material. Specific Implementation Example 2:

[0058] like Figures 7-12 As shown, the difference between this embodiment and specific embodiment 1 is that:

[0059] The first limiting structure, the second limiting structure, and the third limiting structure adopt a different method;

[0060] The first limiting structure includes a first sliding groove 206 radially arranged on the inner side wall of the outer shell 1 and a first limiting member 2071 slidably matched with the first sliding groove 206 on the lower side of the bottom sleeve 2. The end of the first sliding groove 206 near the opening of the outer shell 1 is provided with a first limiting groove 2061 that matches the first limiting member 2071 for limiting. The first limiting groove 2061 is recessed further inward based on the first sliding groove 206, so that when the first limiting member 2071 moves to this position, it is stuck in the first limiting groove 206 under the action of a spring, preventing retraction and thus achieving limiting, preventing the bottom sleeve 2 from being thrown out.

[0061] The second limiting structure includes a second sliding groove 208 radially disposed on the inner side wall of the rear sleeve 2 of the two adjacent sleeves 2, and a second limiting member 2072 whose bottom of the front sleeve 2 slides in cooperation with the second sliding groove 208. The end of the second sliding groove 208 is provided with a second limiting groove 2081 that matches the second limiting member 2072 for limiting. The second limiting groove 2081 is recessed further inward based on the second sliding groove 208, so that when the second limiting member 2072 moves to this position, it is stuck in the second limiting groove 2081 under the action of a spring, thus preventing retraction and achieving limiting; preventing the front sleeve 2 from being thrown out of the rear sleeve 2.

[0062] The third limiting structure includes a third limiting member 4021 disposed on the elastic connecting post 402 and a third limiting member 4021 disposed on the lower side wall of the elastic connecting post 402 and slidingly engaged with the second sliding groove 208 inside the foremost sleeve 2. The end of the second sliding groove 208 inside the foremost sleeve 2 is provided with a third limiting groove 2082 that matches the third limiting member 4021 for limiting. The third limiting groove 2082 is recessed further inward based on the second sliding groove 208, so that when the third limiting member 4021 moves to this position, it is stuck in the third limiting groove 2082 under the action of a spring, preventing retraction and thus achieving limiting; preventing the elastic connecting post 402 from being thrown out of the foremost sleeve 2.

[0063] Among them, the first limiting member 2071, the second limiting member 2072, and the third limiting member 4021 are all in the form of protruding pillars. Of course, other forms such as protrusions, sliders, and balls, which produce the same technical effect, are all within the protection scope of this technical solution.

[0064] The first limiting member 2071 and the second limiting member 2072 are both located on both sides of the connecting rod 207 inside the sleeve 2, and the third limiting member 4021 is located on the lower side wall of the elastic connecting column 402. Each limiting member adopts a columnar structure with ball bearings at the ends. The first limiting member 2071 and the second limiting member 2072 are inserted into the groove holes on the side of the connecting rod 207, and the third limiting member 4021 is inserted into the groove hole on the side wall of the elastic connecting column 402. A spring is provided in the groove hole, so that the limiting member has a forward pressing force in the groove hole, thereby causing the first limiting member 2071, the second limiting member 2072, and the third limiting member 4021 to move forward. After moving to the top, the positioning component 4021 is respectively locked in the first limiting groove 206, the second limiting groove 2081, and the third limiting groove 2082 under the action of the spring, preventing it from being thrown out; one end of the spring is fixedly connected to the bottom or side of the limiting component, and the other end is fixedly connected to the bottom surface of the groove hole; the connecting rod 207 is horizontally arranged in the sleeve 2 and is fixedly connected, such as by thread or snap-fit; in this preferred embodiment, the first limiting component 2071 and the second limiting component 2072 are arranged on both sides of the connecting rod 207, which can also improve the structural strength of the first limiting component 2071 and the second limiting component 2072 and increase their service life;

[0065] This utility model discloses a telescopic drone capture device, which consists of a shell, a telescopic component, and a capture component. The telescopic component is formed by multiple sleeves that are interlocked. The capture component includes an elastic connecting rod and an elastic capture net. A compression spring is provided inside the shell to connect the bottommost sleeve and the bottom of the shell. Blocking components are installed on both sides of the front end of the shell through insertion limiting holes. After the telescopic component and the capture component are retracted into the shell, they are blocked and limited. In use, hold the shell with the front opening facing the drone, pull out the blocking components and throw out the multiple interlocked sleeves. At the same time, the elastic connecting rod and the elastic capture net at the front end are also thrown out from the frontmost sleeve. The elastic capture net opens from a retracted and rolled-up state to form a net.

[0066] If a spring is provided, after the blocking component is pulled out, the bottom sleeve is pushed forward quickly along the opening by the spring. After the bottom sleeve is blocked by the first limiting structure, multiple sleeves that are interlocked are thrown out. At the same time, the elastic connecting rod and the elastic capture net at the front end are also thrown out from the sleeve at the front end. The elastic capture net opens from a contracted and coiled state to form a net.

[0067] By waving the handheld casing, the elastic capture net traps the approaching drone. The drone's propellers, held captive by the net, lose balance and control, thus capturing the drone. After use, the capture net is rotated, compressed, and folded in half. This process is repeated until the diameter of the compressed net is smaller than the diameter of the connecting rod 403. The capture net and connecting rod are then pushed under the limiting device, and finally, the blocking component is installed to complete the storage. This capture device is ingenious and simple in structure, easy to carry and use, has no complex structure, low manufacturing and operating costs, and can be recycled and reused.

[0068] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
