Description

Technical Field

[0001] This invention relates to the field of drone technology, specifically to a quick battery replacement device for cargo drones. Background Technology

[0002] As an important tool for logistics transportation, the efficiency of the replacement of the power battery of cargo drones directly affects the drone's turnaround time and operating costs. At present, cargo drones usually use large-capacity lithium battery packs to meet the requirements of long range and heavy load. The weight of a single battery pack can reach 20kg to 50kg. The battery compartments of existing cargo drones mostly use plug-in connections and strap fixation. During flight, vibrations can easily cause them to loosen, resulting in the battery disconnecting from the drone. This poses a safety hazard during drone flight and may even lead to accidents and property damage in severe cases. Summary of the Invention

[0003] The purpose of this invention is to provide a quick battery replacement device for cargo drones to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a quick battery replacement device for a cargo drone, comprising a drone, wherein a control mechanism is installed at the bottom of the drone, and a fixing mechanism is provided inside the drone; The control mechanism includes two sets of support frames installed at the bottom of the drone. Each set of support frames has a shelf inside, and each set of support frames has a movable rod inside. One end of each set of movable rods is connected to the drone, and a control column is installed on the shelf. The fixing mechanism includes a battery compartment inside the drone, a movable plate movably connected to one side of the control column, the movable plate rotating at the bottom of the drone, a baffle hinged to one end of the movable plate, the baffle moving inside the battery compartment, and a fixing plate moving inside the battery compartment.

[0005] Preferably, a horizontal plate is installed on the shelf, the horizontal plate is connected to the control column, two sets of springs are installed inside each of the two sets of support frames, and one end of each of the multiple sets of movable rods is connected to a spring.

[0006] Preferably, a housing is installed on the outside of the movable plate, and the movable plate moves inside the housing.

[0007] Preferably, a rotating shaft runs through the interior of the movable plate, and both ends of the rotating shaft are respectively connected to the UAV for rotation.

[0008] Preferably, the battery compartment has a sliding groove inside, and one side of the battery compartment has an inclined surface design.

[0009] Preferably, a telescopic rod is installed at one end of the fixed plate, the telescopic rod passes through the drone and connects to the fixed plate, and one end of the movable plate contacts the telescopic rod when it moves.

[0010] Preferably, the drone is equipped with a grasping component, and the drone uses the grasping component to carry out the transport.

[0011] Compared with the prior art, the beneficial effects of the present invention are: 1. When the drone takes off, the movable plate moves and presses the telescopic rod to extend and retract, thereby causing one side of the fixed plate to press against the battery pack inside the battery slot. This increases the fixing effect on the battery pack and prevents the battery pack from detaching from the drone due to shaking during flight, which would affect the normal operation of the battery pack.

[0012] 2. When the drone lands on the ground, the movable rod and support frame weigh down the drone, and the spring is in a compressed state. At the same time, the movable plate moves downward relative to the control column. The control column presses one side of the movable plate, and the movable plate rotates outward around the axis under the push of the control column. When the movable plate rotates, one end of it pushes the baffle downward. At this time, the opening of the battery slot is fully open, and the battery pack can be easily pushed in or taken out, which is convenient for staff to quickly replace the drone battery pack.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1 to 6 The present invention provides a quick battery replacement device for cargo drones, including a drone 1, a control mechanism 2 installed at the bottom of the drone 1, and a fixing mechanism 3 inside the drone 1; The control mechanism 2 includes two sets of support frames 21 installed at the bottom of the drone 1. The two sets of support frames 21 are equipped with shelves 22. Each set of support frames 21 has movable rods 23 inside. One end of each set of movable rods 23 is connected to the drone 1. Control columns 26 are installed on the shelves 22. The fixing mechanism 3 includes a battery compartment 35 inside the drone 1, a movable plate 32 movably connected to one side of the control column 26, the movable plate 32 rotates at the bottom of the drone 1, a baffle 34 is hinged to one end of the movable plate 32, the baffle 34 moves inside the battery compartment 35, and a fixing plate 37 moves inside the battery compartment 35.

[0017] When the drone 1 lands on the ground, the movable rod 23 and the support frame 21 weigh down the drone 1, the spring 25 is compressed, and the movable plate 32 moves downward relative to the control column 26. The control column 26 presses one side of the movable plate 32, and the movable plate 32 rotates outward around the pivot 33 under the push of the control column 26. When the movable plate 32 rotates, one end of it pushes the baffle 34 downward. At this time, the opening of the battery slot 35 is fully open, and the battery pack can be easily pushed in or taken out.

[0018] Meanwhile, after the drone 1 takes off, the support frame 21 moves downward relative to the drone 1, thereby driving the movable plate 32 to rotate in the opposite direction through the control column 26. The movable plate 32 rotates around the pivot 33, and one side of the movable plate 32 drives the baffle 34 to rise, covering the opening of the battery slot 35, thereby preventing the battery from falling off when the drone 1 is flying.

[0019] Simultaneously, during takeoff, the movable plate 32 moves to compress and extend the telescopic rod 38, thereby causing one side of the fixed plate 37 to compress the battery pack inside the battery slot 35, thus increasing the fixing effect on the battery pack and preventing the battery pack from detaching from the drone 1 due to shaking during flight, which would affect the normal operation of the battery pack. When the drone 1 lands, the movable plate 32 rotates to cancel the compression on the battery pack, thus facilitating the quick replacement of the battery pack.

[0020] In an optional embodiment, a horizontal plate 24 is installed on the shelf 22, the horizontal plate 24 is connected to the control column 26, and two sets of springs 25 are installed inside each of the two sets of support frames 21, and one end of each of the multiple sets of movable rods 23 is connected to the spring 25.

[0021] It should be noted that the control column 26 is moved by the horizontal plate 24, and the movable rod 23 is moved inside the support frame 21 by multiple sets of springs 25.

[0022] In an optional embodiment, a housing 31 is mounted on the outside of the movable plate 32, and the movable plate 32 moves inside the housing 31.

[0023] It should be noted that the movable plate 32 rotates inside the outer casing 31 to prevent external objects from contacting the movable plate 32 during the flight of the drone 1 and affecting the operation of the device, thus protecting the movable plate 32.

[0024] In an optional embodiment, a pivot 33 extends through the interior of the movable plate 32, with both ends of the pivot 33 being rotatably connected to the UAV 1.

[0025] It should be noted that the movable plate 32 rotates around the pivot 33, thereby restricting the movable plate 32.

[0026] In an optional embodiment, the battery slot 35 has a groove 36 inside, and one side of the battery slot 35 is designed with a slope.

[0027] It should be noted that the slide 36 and the inclined surface on one side of the battery slot 35 make it convenient for users to insert the battery pack into the battery slot 35 for normal operation.

[0028] In an optional embodiment, a telescopic rod 38 is installed at one end of the fixed plate 37. The telescopic rod 38 passes through the UAV 1 and connects to the fixed plate 37. When the movable plate 32 moves, one end contacts the telescopic rod 38.

[0029] It should be noted that when the drone 1 takes off, it moves the movable plate 32. When the movable plate 32 moves, it squeezes the telescopic rod 38, thereby pushing the fixed plate 37 to squeeze the battery pack, preventing the battery pack from detaching from the drone 1 due to shaking during flight.

[0030] In an optional embodiment, the drone 1 is equipped with a gripping component, which is used by the drone 1 to carry out the transport.

[0031] It should be noted that the grabbing component is used to grab the items that need to be moved, thereby carrying out freight operations.

[0032] Working principle: When the drone 1 lands on the ground, the movable rod 23 and the support frame 21 weigh down the drone 1, the spring 25 is in a compressed state, and at the same time the movable plate 32 moves downward relative to the control column 26. The control column 26 presses one side of the movable plate 32. Under the push of the control column 26, the movable plate 32 rotates outward around the pivot 33. When the movable plate 32 rotates, one end of it pushes the baffle 34 downward. At this time, the opening of the battery slot 35 is fully open, and the battery pack can be easily pushed in or taken out.

[0033] At the same time, after the drone 1 takes off, the support frame 21 moves downward relative to the drone 1, thereby driving the movable plate 32 to rotate in the opposite direction through the control column 26. The movable plate 32 rotates around the pivot 33, and one side of the movable plate 32 drives the baffle 34 to rise, covering the opening of the battery slot 35.

[0034] At the same time, during takeoff, the movable plate 32 moves to compress the telescopic rod 38 to extend and retract, thereby causing one side of the fixed plate 37 to compress the battery pack inside the battery slot 35.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
