DETAILED DESCRIPTION

[0022] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] like Figures 1 to 6 As shown, an embodiment of the present invention provides an interface device for quickly releasing items, including a sleeve 1, an inner sleeve 2, an electromagnet 3, a compression spring 4 and a bayonet 5. The sleeve 1 is provided with an inner cavity, which includes a conical section and a cylindrical section; the inner sleeve 2 is arranged in the inner cavity and can slide relative to the inner cavity, and the inner sleeve 2 is provided with a plurality of balls 21 distributed along the circumferential direction; the electromagnet 3 is arranged in the inner cavity and located above the inner sleeve 2, and the electromagnet 3 can drive the inner sleeve 2 to move relative to the sleeve 1; one end of the compression spring 4 abuts against the electromagnet 3, and the other end of the compression spring 4 abuts against the inner sleeve 2; the bayonet 5 is plugged with the inner sleeve 2 and can abut against the balls 21 for locking.

[0025] The inner sleeve 2 of the present invention can lock the latch 5 under normal conditions. When the item needs to be released, the magnetic force generated by the electromagnet 3 pulls the inner sleeve 2 to move upward along the sleeve 1, and the steel ball 21 loses the constraint of the sleeve 1 and rolls outward, loosening the latch 5 to complete the rapid release of the item.

[0026] The inner sleeve 2 is provided with a guide post and a step surface, and the compression spring 4 is sleeved on the guide post and abuts against the step surface. The guidance of the compression spring 4 can be achieved by arranging the guide post and the step surface, and the eccentric falling of the compression spring 4 can be avoided.

[0027] It should be noted that the inner sleeve 2 has three evenly distributed spherical holes for placing the steel balls 21 . The fit between the spherical holes and the steel balls 21 is a clearance fit, and the surface finish of the spherical holes is Ra1.6 to Ra0.8.

[0028] Furthermore, the inner sleeve 2 has a locking position and an unlocking position.

[0029] When in the locked position, the inner sleeve 2 is placed at the tapered section under the action of the compression spring 4, the outer side of the ball 21 abuts against the wall of the tapered section, and the inner side of the ball 21 abuts against the bayonet pin 5 for locking;

[0030] In the unlocking position, the inner sleeve 2 is placed at the cylindrical section under the action of the electromagnet 3 , the outer side of the ball 21 is disengaged from the wall of the cylindrical section, and the inner side of the ball 21 is disengaged from the latch 5 .

[0031] In the embodiment of the present invention, the inner sleeve 2 is in a locked position under normal conditions. When unlocking is required, a power-on signal can be given to the electromagnet through remote control or code scanning control equipment to complete the unlocking operation.

[0032] The interface device for quickly placing items also includes an upper cover plate 6, which is connected to the sleeve 1 and covers the electromagnet 3. The electromagnet 3 is provided with a pin 31, and the upper cover plate 6 is provided with a through hole matched with the pin 31.

[0033] The upper cover 6 serves to connect and protect, and is used to seal the inner cavity to prevent dust and rain from entering. The upper cover 6 is provided with a mounting hole 61, through which it can be connected to the fuselage structure of the drone. Of course, other mounting connection structures can also be used for connection. Any structure that can achieve the function of connecting to the fuselage structure of the drone should be within the protection scope of this application.

[0034] Furthermore, the bayonet 5 includes a conical surface segment 51 and a cylindrical surface segment 52 connected in sequence, and the large diameter end of the conical surface segment 51 is connected to the end of the cylindrical surface segment 52. The conical surface segment 51 is a guide segment, which is used to push the steel ball 21 when the bayonet 5 is inserted into the inner sleeve 2, so that the steel ball 21 abuts against the wall of the conical segment. The cylindrical surface segment 52 is the contact segment of the steel ball 21 when it is in the locking position, and is used for stable locking. Of course, the cylindrical surface segment 52 can be replaced with other shapes as needed, and they are not described one by one here.

[0035] Preferably, a knurling structure 53 is provided on the outer periphery of the cylindrical surface segment 52, which can increase the friction between the steel ball 21 and the bayonet 5 and improve the overall lifting load. The lower end structure of the bayonet 5 can be selected according to needs, for example, Figure 6 As shown, it can be a cylindrical or annular structure, or other structures.

[0036] It should be noted that the inner sleeve 2 can be made of ferromagnetic stainless steel material, the spring and steel balls can be made of stainless steel material, and the remaining parts can be made of other suitable materials based on the usage scenario by comprehensively considering factors such as manufacturability and economy.

[0037] Preferably, when the embodiment of the present invention is assembled with a drone, a single assembly method or a multiple interval assembly method can be adopted, so as to adapt to different application scenarios and load various sizes of loads.

[0038] The above is only a specific embodiment of the present invention, and cannot be used to limit the scope of the invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the protection scope of the present invention, should still fall within the scope of this patent. In addition, the technical features of the present invention can be freely combined with each other, with each other, and with each other.
