Description

Technical Field

[0001] This utility model relates to the field of military technology of unmanned aerial vehicles (UAVs), specifically to the connection structure between an impact fuse and a UAV, and a UAV having the structure. Background Technology

[0002] As a type of intelligent equipment that integrates aviation technology, artificial intelligence, the Internet of Things and materials science, drones have achieved leapfrog development in the military, civilian and commercial fields in recent years, especially in the military field.

[0003] In the military field, combining explosives with civilian drones can achieve unexpected results. Detonating explosives requires a fuse, and one type of fuse is the impact fuse. Once the impact fuse touches the target, it can detonate the explosive. It is evident that the impact fuse needs to be fixed to the drone. Considering that the above implementation method is very simple, how to achieve the above fixed connection function with high applicability (being able to be fixed with many types of drones) is a problem that urgently needs to be solved by those skilled in the art (the structure must ensure that the impact fuse is outside the range of the drone propeller to avoid failing to hit the target). Summary of the Invention

[0004] The purpose of this invention is to provide a connection structure between an impact fuse and a drone, and a drone with this structure, so as to achieve the function of fixing the fuse to a drone with high applicability (it can be fixed with many types of drones).

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] The connection structure between the impact fuse and the UAV and the UAV having the structure include a fixed plate and an extension arm vertically fixed to the fixed plate. The end of the extension arm away from the fixed plate is provided with a fixing structure for mounting the impact fuse. The extension arm can be extended in the length direction so that the position of the fixing structure at the end of the extension arm is adjustable along the length direction of the extension arm.

[0007] Furthermore, the fixing plate includes a plastic plate body and an oblong hole formed in the thickness direction of the plastic plate body.

[0008] Furthermore, the extension arm includes an inner arm rod that is fixed perpendicularly to the plastic plate and a sleeve arm sleeve that is sleeved outside the inner arm rod. A limiting mechanism is provided between the inner arm rod and the sleeve arm sleeve to limit the relative displacement between the inner arm rod and the sleeve arm sleeve.

[0009] Furthermore, both the inner arm rod and the sleeve arm have transversely constructed limiting holes, and the multiple limiting holes are arranged at equal intervals. The inner arm rod and the sleeve arm have movable grooves that communicate with the multiple limiting holes.

[0010] Furthermore, the limiting mechanism includes a screw that passes through the inner arm rod and the limiting hole on the sleeve, and a nut that is threaded to the end of the screw and close to the outer wall of the sleeve.

[0011] Furthermore, the fixing structure includes a pair of L-shaped rods fixed to the end of the sleeve, the ends of the L-shaped rods being constructed with a pressing surface that presses against the locking point of the impact fuse tail, and the L-shaped rods being made of tough plastic.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] The impact fuze and UAV connection structure and the UAV with this structure provided in this embodiment are mainly used to solve the problem of how to fix the impact fuze to the UAV with high applicability (it can be fixed with many types of UAVs), and the following technical solution is provided, which will be combined with the following. Figures 1-7 Please provide a detailed explanation:

[0026] A connection structure between an impact fuse and a drone includes a fixing plate 1 for connection to the outer wall of the drone's casing, and an extension arm 2 vertically fixed to the fixing plate 1. The end of the extension arm 2, away from the fixing plate 1, has a fixing structure 3 for mounting the impact fuse. To better adapt to various civilian drones, the extension arm 2 can be extended in length, allowing the fixing structure 3 at the end of the extension arm 2 to be adjustable along its length. (See also...) Figure 2 This was the initial product design of this application, and its shortcomings were obvious. It was not highly adaptable to use with civilian drones of varying wingspans. In order to adapt to actual conditions, this application designed the following... Figure 3 The improved product features an extension arm 2 that can be extended in length to accommodate civilian drones with different wingspans. Specifically, the fixing plate 1 includes a plastic plate 101 and an oblong hole 102 constructed along the thickness of the plastic plate 101. The plastic material is chosen for its light weight, and the oblong hole 102 better accommodates the area where the fixing screws are installed. The extension arm 2 includes an inner arm rod 21 perpendicularly fixed to the plastic plate 101 and a sleeve arm 22 sleeved around the inner arm rod 21, allowing the sleeve arm 22 to move along the outside of the inner arm rod 21. A limiting mechanism 23 is provided between the inner arm rod 21 and the sleeve arm 22 to limit the relative displacement between them. The specific operation of the limiting mechanism is detailed in [link to details]. Figure 3 , Figure 4Both the inner arm rod 21 and the sleeve arm 22 have transversely constructed limiting holes 24, which are arranged at equal intervals. Simultaneously, the inner arm rod 21 and the sleeve arm 22 have movable grooves 25 communicating with the multiple limiting holes 24. The limiting mechanism 23 includes a screw 231 that passes through the limiting holes 24 on the inner arm rod 21 and the sleeve arm 22, and a nut 232 threadedly connected to the end of the screw 231 and tightly against the outer wall of the sleeve arm 22. When an extension operation is required, the movable sleeve arm 22 moves along the inner arm rod 21. When the device is near the required position (this application does not need to be so precise, it only needs to be a certain distance beyond the maximum range of the drone's wings), the limiting holes 24 on both devices are aligned, and then the screw 231 is passed through, and the nuts 232 are tightened at both ends. This application uses plastic products for both the fixing plate 1 and the extension arm 2, which reduces the product cost. At the same time, the extension function achieved by the sleeve sleeve 22 moving along the inner arm rod 21 allows the product to be matched with civilian drones with different wingspans, achieving a highly applicable function.

[0027] This application also includes a fixing structure 3 for securing the impact fuse, as detailed in [link to application]. Figure 6 as well as Figure 7 The fixing structure 3 includes a pair of L-shaped rods 31 fixed to the end of the sleeve 22. The ends of the L-shaped rods 31 are constructed with pressure surfaces 32 that press against the locking point of the impact fuse tail. The L-shaped rods 31 are made of tough plastic. The specific locking method is as follows: Figure 4 As can be seen, it is necessary to further explain that the snap-fit ​​method is for the tail snap-fit ​​method of the impact fuze shown in the figure. It can be improved according to the actual impact fuze structure. In other words, the specific disclosure of this application should not be used to limit this application.

[0028] A drone, wherein the fixing plate 1 is fixed to the drone shell by bolts passing through the waist-shaped hole 102, and the fixing position can be selected according to the actual situation.
