[0033] The embodiment of the present application provides a light weapon rack for a drone, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a shell 100, a hook 200, a rocker arm 300, a connecting plate 400, a brake arm 500 and a push-pull electromagnet 600, wherein the shell 100 is a structure for installing and supporting other components, the hook 200 is a structure for mounting weapons, and the rocker arm 300, the connecting plate 400, the brake arm 500 and the push-pull electromagnet 600 realize the action control of the hook 200, which can realize the release of the weapon.

[0034] like Figure 1 and Figure 2 As shown, the shell 100 is provided with a connecting hole 110 and an electrical interface 120. An ear plate is provided at the edge of the shell 100, and the connecting hole 110 is provided on the ear plate. The entire shell 100 can be installed on the bottom of the drone through the connecting hole 110 to achieve mechanical connection with the drone. A quick-plug connector can be provided at the electrical interface 120 to achieve electrical connection with the drone, thereby achieving communication and power supply.

[0035] like Figure 3As shown, the middle part of the hook 200 is rotatably connected to the housing 100, the bottom of the hook 200 forms a hook portion and extends out of the housing 100, and the upper part of the hook 200 is connected to a tension spring 210, and when the tension spring 210 contracts, it can drive the hook 200 to rotate clockwise. In practice, the tension spring 210 can be set to make the hook 200 in a state of releasing the weapon, that is, when the hook 200 is not subjected to other forces, the tension spring 210 tightly pulls the hook 200.

[0036] like Figure 3 As shown, the rocker arm 300 is rotatably connected in the shell 100 and is generally located on the upper part of the hook 200. The first end of the connecting plate 400 is rotatably connected to the top of the hook 200, and the second end of the connecting plate 400 is rotatably connected to the middle part of the rocker arm 300. The connecting plate 400 connects the hook 200 and the rocker arm 300 to achieve linkage.

[0037] like Figure 3 As shown, the middle part of the brake arm 500 is rotatably connected to the housing 100, and a torsion spring 510 is provided on the brake arm 500. When the brake arm 500 is subjected to force and rotates counterclockwise, the torsion force of the torsion spring 510 increases. After the external force disappears, the torsion spring 510 can drive the brake arm 500 to return to its original position.

[0038] like Figure 3 As shown, the push-pull electromagnet 600 is disposed at the brake arm 500 , and the push-pull electromagnet 600 can drive the brake arm 500 to rotate counterclockwise when pushed out.

[0039] like Figure 4 and Figure 5 As shown, when the hook 200 rotates counterclockwise, the connecting plate 400 drives the rocker arm 300 to rotate clockwise, so that the rocker arm 300 can abut against the brake arm 500 and drive the brake arm 500 to rotate counterclockwise. As the brake arm 500 rotates, the rocker arm 300 can pass over the brake arm 500. At this time, the brake arm 500 abuts against the bottom of the rocker arm 300 to prevent the rocker arm 300 from rotating counterclockwise.

[0040] like Figure 4 and Figure 5 As shown, when the push-pull electromagnet 600 is pushed out, it can drive the brake arm 500 to rotate counterclockwise, and the brake arm 500 is separated from the rocker arm 300, and no longer blocks the movement of the rocker arm 300, and the rocker arm 300 can rotate counterclockwise.

[0041] When no weapon is mounted, the hook 200 is in a released state (i.e. Figure 4When in use, the user can hold the weapon and use the lifting ear on the weapon to push the hook 200 upwards, so that the hook 200 rotates counterclockwise, and the hook 200 drives the rocker arm 300 to rotate clockwise through the connecting plate 400, and the rocker arm 300 will abut against the brake arm 500 until it passes over the brake arm 500 (i.e. Figure 5 The weapon is now hooked on the hook 200, and the rocker arm 300 cannot rotate clockwise due to the blocking effect of the brake arm 500, and the weapon is securely hooked on the hook 200. When the weapon needs to be released, the push-pull electromagnet is pushed out, driving the brake arm 500 to rotate counterclockwise, and the brake arm 500 is separated from the rocker arm 300 and no longer blocks the rocker arm 300. Under the tension of the tension spring 210, the hook 200 rotates clockwise, and the weapon is released.

[0042] Compared with the existing technology, the light weapon rack for UAV can realize the mounting and releasing of weapons, uses fewer parts, has a simpler structure, simplifies the movement process of components, and reduces production costs and assembly time.

[0043] In some embodiments, Figure 2 As shown, the light weapon rack for unmanned aerial vehicles also includes a weapon positioning assembly 700, which includes two positioning plates 710 and four clamping bolts 720. The positioning plates 710 are generally in an arc-shaped structure, which matches the appearance of the weapon. The two positioning plates 710 are arranged at intervals along the length direction of the shell 100, and can generally position the head and tail of the weapon. Two clamping bolts 720 are arranged on each positioning plate 710. The clamping bolts 720 are arranged at both ends of the positioning plate 710 to generally form a V shape, so that the two clamping bolts 720 can be clamped in a V shape. A rubber pad can be set at one end of the clamping bolt 720 close to the weapon to increase friction and reduce wear on the weapon.

[0044] In some embodiments, Figure 3 As shown, a photoelectric sensor 130 is provided in the shell 100, and the photoelectric sensor 130 detects downward. The shell 100 is provided with a corresponding through hole. When a weapon is hung on the hook 200, the photoelectric sensor 130 can detect the weapon, thereby providing feedback to the drone on whether the weapon is mounted.

[0045] In some embodiments, Figure 4 and Figure 7As shown, the lower part of the brake arm 500 is provided with an operation hole 520, and the housing 100 is provided with an arc-shaped release hole 140. The operation hole 520 is opposite to the arc-shaped release hole 140. When the push-pull electromagnet 600 is pushed out, the brake arm 500 rotates along the arc-shaped release hole 140. In other words, when the brake arm 500 moves along the arc-shaped release hole 140, the weapon can be released. In this way, when the push-pull electromagnet 600 fails or is not powered, a plug shaft can be inserted into the operation hole 520, and then moved along the arc-shaped release hole 140 to realize the function of manually releasing the weapon.

[0046] In some embodiments, Figure 1 and Figure 4 As shown, the housing 100 is provided with a safety hole 150, which is located on the path of the hook 200 for releasing the weapon. After the weapon is hooked on the hook 200, a pin (safety pin) can be inserted into the large safety hole 150, so that the pin can block the rotation of the hook 200, so that the hook 200 cannot release the weapon, thereby avoiding the situation where the weapon is released due to accidental power-on or misoperation.

[0047] In some embodiments, Figure 1 and Figure 4 As shown, the housing 100 is provided with an observation hole 160, which is located at the abutment position after the rocker arm 300 passes over the brake arm 500. Through the observation hole 160, the rocker arm 300 and the brake arm 500 can be observed at the same time, and the abutment between the two is observed, which proves that the movable hook 200 has been locked.

[0048] In some embodiments, Figure 1 As shown, the housing 100 includes a left half shell 170 and a right half shell 180, which are buckled together to facilitate installation of various parts in the housing 100. In implementation, various structures on the left half shell 170 and the right half shell 180 can be symmetrically arranged.

[0049] Generally, the wall thickness of the housing 100 is small and the structural strength is low. Figure 2 As shown, the light weapon rack for unmanned aerial vehicles also includes a left mounting plate 800 and a right mounting plate 900. The left mounting plate 800 is detachably connected to the left half shell 170, and the right mounting plate 900 is detachably connected (generally bolted) to the right half shell 180. An installation space is formed between the left mounting plate 800 and the right mounting plate 900. By installing the left mounting plate 800 on the left shell 100 and the right mounting plate 900 on the right shell 100, the structural strength of the left shell 100 and the right shell 100 can be enhanced, and the overall strength of the shell 100 can be enhanced. In practice, the left shell 100 and the left mounting plate 800 can also be made into one part, without the need to assemble the two again, but the manufacturing process is slightly more complicated.

[0050] like Figure 3 As shown, the hook 200, the rocker arm 300 and the brake arm 500 are all located in the installation space, and the above parts are all rotatably connected to the left mounting plate 800 and the right mounting plate 900 to realize the rotational installation of these parts, and then the left mounting plate 800 and the right mounting plate 900 are integrally installed on the left half shell 170 and the right half shell 180 to form an integral installation module, which is easier to install.

[0051] Of course, through holes corresponding to the hole structures such as the operation hole 520, the arc-shaped release hole 140, the safety hole 150 and the observation hole 160 are opened on the left mounting plate 800 and the right mounting plate 900 to realize the functions of the hole structures.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
