Description

Technical Field

[0001] This utility model relates to the field of drone delivery technology, specifically to a self-testing drone delivery device. Background Technology

[0002] While drones are increasingly used in logistics and emergency rescue, their delivery systems still suffer from significant shortcomings. Existing drone delivery systems mainly fall into two categories: First, there are cable tie-type delivery systems, which use servo motors to release items by loosening elastic bandages. However, when the bandages loosen, the items are easily thrown upwards due to inertia, threatening the drone's propellers. Furthermore, they lack status monitoring capabilities, resulting in a high risk of delivery failure. Second, there are lever-type delivery systems, which rely on high-precision assembly of levers and holes for delivery. However, these systems require strict parallelism, are prone to jamming and malfunction, and similarly lack delivery status feedback. In addition, existing devices are mostly customized for specific drone models, lacking versatility and adapting poorly to diverse platforms. Therefore, there is an urgent need for a drone delivery system that is simple in structure, possesses self-checking capabilities, is highly versatile, and is safe and reliable, to address the core issues of existing technologies, such as complex structure, insufficient reliability, lack of status feedback, and poor adaptability. Utility Model Content

[0003] Based on this, and in response to the above problems, this utility model proposes a self-testing drone delivery device, which solves the problems of existing drone delivery devices being unable to provide feedback on delivery status, having poor versatility, and being difficult to adapt to diverse platforms.

[0004] The technical solution of this utility model is:

The lower end of the sliding member is provided with a hook body, which is located on one side of the bottom of the fixed body. The other side of the bottom of the fixed body is provided with a locking member that cooperates with the hook body. When the sliding member slides to the side close to the driving member, the hook body at the lower end of the sliding member and the locking member at the lower end of the fixed body form a hook-lock structure.

[0007] The switch is located inside the hook body, and the spring pin is located on the locking member. One end of the spring pin passes through the locking member. When the object is delivered, the spring pin contacts the switch to trigger the switch.

[0008] Preferably, the output shaft of the drive component is connected to the slider via a transmission assembly for driving the slider;

[0009] The transmission assembly includes a transmission flange and a threaded transmission shaft. The driving component is a servo motor. The output shaft of the servo motor is connected to the transmission shaft through the transmission flange, and the transmission shaft is connected to a sliding component.

[0010] Preferably, the threaded drive shaft is disposed within the fixed body, with both ends of the threaded drive shaft passing through the fixed body and rotatably connected to it. The sliding component is sleeved on the threaded drive shaft and threadedly connected to it. The driving component is a servo motor, which is fixedly connected to the fixed body. The output shaft of the servo motor is fixedly connected to one end of the threaded drive shaft for driving it.

[0011] Preferably, the output shaft of the servo motor is provided with a first flange, and the threaded drive shaft is provided with a second flange that mates with the first flange, and the first flange and the second flange are fixedly connected by bolts;

[0012] The output shaft of the servo motor is connected to the threaded drive shaft via a flange. The fixed body is equipped with a guide rail that matches the sliding component, and the sliding component is slidably mounted on the guide rail.

[0013] Preferably, both ends of the threaded drive shaft are rotatably connected to the fixed body via bearings.

[0014] Preferably, the sliding component includes a sliding block, a limiting block, and a limiting bolt. The limiting block is disposed on the top of the sliding component, and the limiting bolt is disposed on the top of the limiting block. One end of the limiting bolt passes through the limiting block and is threadedly connected to the top of the sliding component. The fixing body has a sliding groove that cooperates with the sliding component. The sliding component is slidably disposed in the sliding groove and slidably connected to the sliding groove. The fixing body has a limiting groove that cooperates with the limiting block. The limiting groove passes through both sides of the fixing body and communicates with the sliding groove. The limiting block is slidably disposed in the limiting groove. The top of the fixing body has a limiting window that communicates with the limiting groove. The limiting bolt is slidably disposed in the limiting window. The sliding component is sleeved on the threaded drive shaft and is threadedly connected to the threaded drive shaft.

[0015] Preferably, the spring pin includes a spring-loaded locking member, a telescopic rod, and a spring. The spring-loaded locking member is disposed on the locking member, one end of which passes through the locking member and is fixedly connected to the locking member by bolts.

[0017] Preferably, a pull ring is fixedly provided at the other end of the telescopic rod.

[0018] Preferably, the switch is a self-resetting jog switch;

[0019] When the item is not being delivered, the telescopic rod of the spring pin is in a compressed and retracted state, and the jog switch is not triggered. When the item is delivered, the telescopic rod of the spring pin extends, causing the triggering part to activate the jog switch.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In use, this invention uses a driving component to drive a sliding component, which in turn moves the hook at the lower end of the sliding component, opening or closing the hook-lock structure to complete the delivery or securing of items. When an item is delivered, a spring pin pops out, triggering a jog switch to provide delivery status feedback. This causes the sliding component to slide horizontally on the guide rail, allowing the hook at the lower end of the sliding component to form a hook-lock structure with the locking component at the lower end of the fixing body, thus securing and delivering the item. This solves the problems of existing drone delivery devices that cannot provide delivery status feedback, have poor versatility, and are difficult to adapt to diverse platforms.

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] Example:

[0037] like Figure 1-4 As shown, this is the first embodiment of the present invention, a self-testing drone delivery device, including a fixed body 1, a sliding member 2, a driving member 3, a transmission assembly 9, a switch 4, and a spring pin 5. The driving member 3 is fixed to the fixed body 1, and the driving member 3 is connected to the sliding member 2 through the transmission assembly 9. The sliding member 2 is horizontally slidably fitted into the fixed body 1. The lower end of the sliding member 2 is provided with a hook 6, and the lower end of the fixed body 1 is provided with a locking member 7. When the sliding member 2 slides to the side close to the driving member 3, the hook 6 at the lower end of the sliding member 2 can form a hook-lock structure with the locking member 7 at the lower end of the fixed body 1.

[0038] A switch 4 is provided on the inner side of the hook body 6, and a spring pin 5 is provided on the locking member 7. The spring pin 5 includes a telescopic rod 18, a spring locking member 17, and a spring 19. The spring 19 is located inside the spring locking member 17, and the telescopic rod 18 is inserted through the spring locking member 17. The switch 4 and the spring pin 5 are located on the same horizontal axis.

[0039] In use, this utility model drives the sliding member 2 through the driving member 3, thereby moving the hook body 6 at the lower end of the sliding member 2 to open or close the hook lock structure, thereby completing the placement or fixing of items.

[0040] When the item is not delivered, the spring 19 is in a stretched state, and the telescopic rod 18 is blocked by the delivered item 8, so that the trigger part 20 cannot contact the switch 4; when the item is delivered, the spring 19 returns to a free state, the telescopic rod 18 pops out, and the trigger part 20 at one end of the telescopic rod 18 triggers the switch 4, completing the delivery status feedback.

[0041] In this embodiment, the delivery of items and feedback of the delivery status of items by the drone delivery device are completed only by the cooperation of the fixed body 1, the sliding part 2, the driving part 3, the switch 4, the spring pin 5 and the transmission component 9. This eliminates the complex structure of the existing drone delivery device, reduces manufacturing costs, greatly improves operating efficiency, and solves the problems of existing drone delivery devices that cannot provide feedback on the delivery status, have poor versatility, and are difficult to adapt to diverse platforms.

[0042] To facilitate the sliding of the slider 2, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the output shaft of the driving component 3 is connected to the slider 2 through the transmission component 9 to drive the slider 2.

[0043] The transmission component 9 is a threaded drive shaft 11, which is disposed inside the fixed body 1. Both ends of the threaded drive shaft 11 pass through the fixed body 1 and are rotatably connected to the fixed body 1. The sliding member 2 is sleeved on the threaded drive shaft 11 and is threadedly connected to the threaded drive shaft 11. The driving component 3 is a servo motor, which is fixedly connected to the fixed body 1. The output shaft of the servo motor is fixedly connected to one end of the threaded drive shaft 11 and is used to drive the threaded drive shaft 11.

[0044] In use, the threaded drive shaft 11 can be driven by a servo motor, which in turn drives the sliding member 2 that is threadedly connected to the threaded drive shaft 11, making it easy to drive the sliding member 2 to slide.

[0045] Preferably, the output shaft of the servo motor is provided with a first flange, and the threaded drive shaft 11 is provided with a second flange that cooperates with the first flange. The first flange and the second flange are fixedly connected by bolts.

[0046] When the sliding member 2 is driven by the driving member 3, the output shaft of the servo motor rotates and drives the first flange. The first flange and the second flange are fixedly connected by bolts, and at the same time, the second flange is driven to rotate, thereby driving the threaded drive shaft 11 to rotate.

[0047] By setting the transmission flange 10, reliable transmission of servo motor power can be achieved, ensuring that rotational motion is stably transmitted to the drive shaft.

[0048] In a preferred embodiment of this example, the servo motor and the fixed body 1 are fixedly connected by bolts.

[0049] Using bolted connections makes it easier to install the servo motor.

[0050] In a preferred embodiment of this example, both ends of the threaded drive shaft 11 are rotatably connected to the fixed body 1 via bearings 12.

[0051] In this embodiment, the rotatable connection of the bearing 12 can significantly reduce the frictional resistance when the drive shaft rotates, ensuring smoother servo drive and lower energy consumption. At the same time, the bearing 12 support can reduce the radial runout and axial movement of the drive shaft, improving transmission accuracy and stability.

[0052] like Figure 2 As shown, another embodiment of this utility model is a self-testing drone delivery device. The sliding member 2 includes a sliding block, a limiting block 13, and a limiting bolt 14. The limiting block 13 is disposed on the top of the sliding member 2, and the limiting bolt 14 is disposed on the top of the limiting block 13. One end of the limiting bolt 14 passes through the limiting block 13 and is threadedly connected to the top of the sliding member 2. The fixing body 1 has a sliding groove 15 that cooperates with the sliding member 2. The sliding member 2 is slidably disposed in the sliding groove 15 and slidably connected to the sliding groove 15. The fixing body 1 has a limiting groove that cooperates with the limiting block 13. The limiting groove passes through both sides of the fixing body 1 and communicates with the sliding groove 15. The limiting block 13 is slidably disposed in the limiting groove. The top of the fixing body 1 has a limiting window 16 that communicates with the limiting groove. The limiting bolt 14 is slidably disposed in the limiting window 16. The sliding member 2 is sleeved on a threaded drive shaft 11 and is threadedly connected to the threaded drive shaft 11.

[0053] When the sliding member 2 is driven by the driving member 3 to move away from the driving member 3, the sliding member 2 slides in the sliding groove 15 that is matched with it, and at the same time the limiting block 13 slides in the limiting groove; the limiting bolt 14 slides in the limiting window 16. When the limiting block 13 and the limiting bolt 14 are restricted by the limiting groove and the limiting window 16 and cannot slide, this is the maximum distance range that the sliding member 2 can move.

[0054] In this embodiment, by setting a limiting groove, a limiting window 16, a limiting block 13, and a limiting bolt 14 to cooperate, the structural connection strength is enhanced, and the position of the limiting bolt 14 can be observed through the limiting window 16 to determine the stroke of the sliding member 2, thus achieving visual limiting.

[0055] In one embodiment, the spring pin 5 includes a spring-loaded locking member 17, a telescopic rod 18, and a spring 19. The spring-loaded locking member 17 is disposed on the locking member 7, one end of which passes through the locking member 7 and is fixedly connected to the locking member 7 by bolts. The telescopic rod 18 is disposed inside the spring-loaded locking member 17 and is slidably connected to the spring-loaded locking member 17. One end of the telescopic rod 18 is provided with a trigger part 20, which is fixedly connected to the telescopic rod 18 and slidably engaged with the spring-loaded locking member 17. The spring 19 is disposed inside the spring-loaded locking member 17 and is sleeved on the telescopic rod 18. The telescopic rod 18 is provided with a connecting point. One end of the spring 19 is fixedly connected to the spring-loaded locking member 17, and the other end is fixedly connected to the connecting point.

[0056] The spring 19 is disposed within the spring clip fixing member 17, and the telescopic rod 18 is disposed through the spring clip fixing member 17.

[0057] In this embodiment, a modular structure consisting of spring clip fastener 17, telescopic rod 18, and spring 19 is adopted, which can accurately reflect the delivery status. The standardized component design facilitates mass production and replacement, improves the reliability and maintenance efficiency of the delivery device, and the multiple fixing structures ensure that it is not easy to loosen during long-term use, thus ensuring the stability of the self-test function.

[0058] In a preferred embodiment of this example, the switch 4 is a self-resetting jog switch 4;

[0059] When the item is not delivered, the spring 19 is in a stretched state, and the telescopic rod 18 is blocked by the delivered item 8, so that the trigger part 20 cannot contact the switch 4; when the item is delivered, the spring 19 returns to a free state, the telescopic rod 18 pops out, and the trigger part 20 at one end of the telescopic rod 18 triggers the switch 4, completing the delivery status feedback.

[0060] In this embodiment, the self-resetting jog switch 4 cooperates with the spring pin 5 to compress the telescopic rod 18 when the item is not delivered, so that the switch 4 is not triggered, ensuring a stable signal before delivery; after the item is delivered, the telescopic rod 18 automatically extends to trigger the switch 4, and the delivery completion status can be fed back in real time without additional power.

[0061] In a preferred embodiment of this example, a pull ring 21 is fixedly provided at the other end of the telescopic rod 18.

[0062] When the object 8 is fixed, the telescopic rod 18 is compressed by pulling the pull ring 21 with the adapter or by finger. Then, the fixed part of the object 8 is placed into the reserved hook lock structure, and the pull ring 21 is released to complete the fixing.

[0063] In this embodiment, the pull ring 21 structure increases the point of force for operation, avoiding damage caused by direct contact with the telescopic rod 18, and the standardized pull ring 21 design can be adapted to tool or finger operation.

[0064] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
