Description

Technical Field

[0001] The present invention relates to the technical field of aviation vehicles, and in particular to an unmanned aerial vehicle. Background Art

[0002] The application of drones in various industries is becoming increasingly extensive. At present, drones have been applied to aerial photography, agricultural and forestry plant protection, geological exploration, power inspection, oil and gas pipeline inspection, highway accident management, forest fire inspection, and pollution environment investigation and other fields.

[0003] Among them, multi-rotor drones are a type of drone that can take off and land vertically, and most of them are electric drones. At present, the batteries of multi-rotor drones are usually fixed to the mounting frame of the fuselage with magic ties. Since the magic ties are easily damaged, it is very easy to cause the battery to fall off; or the battery is limited to the mounting frame of the fuselage with a baffle. After a long period of use, the baffle is easily damaged and produces a virtual position, causing the battery to fall off, or causing the drone to generate high-frequency vibrations during operation and affect the control system. Especially for the current large and heavy batteries with large loads and long flight times, the above-mentioned battery fixing method is extremely inconvenient. Summary of the invention

Therefore, they should not be understood as limiting the scope of protection of this embodiment.

[0043] like Figure 1 As shown, an embodiment of the present invention provides a drone, which can be a multi-rotor drone, comprising a fuselage 1, on which a mounting frame 2 is arranged, and on which a first locking portion 4 can be arranged; a battery fixing structure 3, which comprises a fixing body 31, and a housing cavity 311 whose contour shape is adapted to the contour shape of the battery and is used to accommodate the battery can be arranged in the fixing body 31; wherein the fixing body 31 can slide into the mounting frame 2, and the first locking portion 4 can lock the fixing body 31 in the mounting frame 2.

[0044] In some examples, the mounting frame 2 may be a frame structure mainly composed of a bottom plate and two side plates connected to the bottom plate, and a plurality of through holes may be arranged on the bottom plate and the side plates, and the bottom plate and the side plates may be made of carbon fiber material to reduce weight and dissipate heat of the battery. The fixed body 31 of the battery fixing structure 3 may be a rectangular box structure whose width matches the width of the battery, and a partition plate may be provided in the box structure to form a plurality of accommodating cavities 311 that match the battery contour in the fixed body 31 so as to store a plurality of batteries to meet the use requirements of the drone. Specifically, the fixed body 31 may be made of aluminum alloy material, which can not only reduce costs and facilitate processing, but also can be covered with through holes on the surface of the fixed body 31, which can not only play a role in dissipating heat for the battery, but also reduce the weight of the fuselage 1, so that the drone can carry more loads or equipment.

[0045] The drone provided by the embodiment of the present invention provides a first locking portion on the mounting frame of the fuselage, and provides a battery fixing structure including a fixed body, and the fixed body is provided with a accommodating cavity whose contour shape is adapted to the contour shape of the battery, so that the battery of the drone can be accommodated in the accommodating cavity of the fixed body, and the fixed body can slide into the mounting frame, and the first locking portion 4 can lock the fixed body slid into the mounting frame in the mounting frame. In this way, the fixed body accommodating the battery can be fixed in the mounting frame by the first locking portion 4, will not fall off, and will not vibrate. At the same time, since the contour shape of the accommodating cavity is adapted to the contour shape of the battery, the battery will not vibrate in the fixed body and will not fall off, thereby ensuring the normal operation of the drone and convenient use.

[0046] In some examples, the aforementioned first locking portion 4 may have a locked state and an unlocked state; when the first locking portion 4 is in the locked state, the fixed body 31 can be locked in the mounting frame 2; when the first locking portion 4 is in the unlocked state, the fixed body 31 can slide out of the mounting frame 2. When installing the battery, the battery can be accommodated in the fixed body 31 of the battery structure, and then the fixed body 31 is slid into the mounting frame 2, at which time the first locking portion 4 can be in the locked state, thereby locking the fixed body 31 in the mounting frame 2, and keeping the drone in operation without the battery falling off and vibrating; when removing the battery, the first locking portion 4 can be in the unlocked state, and then the fixed body 31 of the battery fixing structure 3 can be slid out of the mounting frame 2, so as to realize the removal of the battery.

[0047] The first locking portion 4 may have various structural forms, as long as it can lock the fixing body 31 in the mounting frame 2 or enable the fixing body 31 to slide out of the mounting frame 2 .

[0048] For some examples, see Figure 2 , and combined with Figure 1The first locking portion 4 may include a first through hole and a second through hole respectively disposed on the mounting frame 2 and the fixing body 31 and opposite to each other; a connecting member 41, which may be connected to the bottom of the mounting frame 2; a handle 42, which may be rotatably connected to the connecting member 41 through an elastic member 43; and a positioning pin 44, one end of which may be rotatably connected to the handle 42, and the other end of which may be inserted into the first through hole and the second through hole.

[0049] In some examples, the first through hole and the second through hole can be set at corresponding positions at the bottom of the mounting frame 2 and the fixed body 31, and the second through hole set on the fixed body 31 can also be a slot, as long as the positioning pin 44 can be inserted into the second through hole or the slot after passing through the first through hole of the mounting frame 2 to lock the fixed body 31. The connecting member 41 can be a connecting plate fixed to the bottom of the mounting frame 2, and in order to save space, a hole can be opened on the connecting plate so that the positioning pin 44 passes through the opening and enters the first through hole and the second through hole. The structure of the handle 42 can include a handle 42 body and an arc plate connected thereto, and the connection between the two is rotatably connected to the connecting member 41 through a fixing member, and the end of the arc plate is rotatably connected to one end of the positioning pin 44; the elastic member 43 can be connected between the connecting member 41 and the arc plate, and the elastic member 43 can be a spring.

[0050] According to the above embodiment, when the handle body is pressed, the arc plate can overcome the elastic force of the elastic member 43 and drive the positioning pin 44 to retract from the second through hole to the first through hole, so that the fixed body 31 can slide out of the mounting frame 2, thereby forming an unlocked state of the first locking portion 4; when the handle body is released, the handle 42 body and the arc plate are reset under the elastic force of the elastic member 43, so that the positioning pin 44 is reset under the drive of the arc plate, that is, it penetrates into the second through hole, locks the fixed body 31 to the mounting frame 2, thereby forming a locked state of the first locking portion 4, with a simple structure and reliable implementation.

[0051] In order to make the fixing body 31 of the battery fixing structure 3 more firmly locked in the mounting frame 2, in some examples, see Figure 3, a limiting plate 21 can be provided at the end of the mounting frame 2, so that when the fixed body 31 slides into the mounting frame 2 and contacts the limiting plate 21, the first locking portion 4 can lock the fixed body 31 in the mounting frame 2. That is to say, when the first locking portion 4 locks the fixed body 31 in the mounting frame 2, the end of the fixed body 31 can contact the limiting plate 21, playing a double limiting and fixing role for the fixed body 31, further ensuring that the fixed body 31 will not vibrate or fall off, and avoiding the displacement of the fixed body during the flight of the drone and affecting the center of gravity of the drone. Moreover, through the setting of the limiting plate 21, it can also play a limiting role for the fixed body 31 to slide into the mounting frame 2, that is, when the end of the fixed body 31 contacts the limiting plate 21, it means that the fixed body 31 slides into place, and at this time, the first locking portion 4 can lock the fixed body 31, which is more convenient to use.

[0052] In order to facilitate the fixing body 31 of the battery fixing structure 3 to slide into or out of the mounting frame 2, in some examples, see Figure 3 A first slide rail 22 may be provided on the mounting frame 2; and a second slide rail 311 for sliding connection with the first slide rail 22 may be provided on the fixed body 31, so that the fixed body 31 can slide into or out of the mounting frame 2 through the first slide rail 22 and the second slide rail 311, thereby allowing multiple batteries to be integrally and conveniently and quickly loaded and unloaded onto the drone.

[0053] Among them, the structural forms of the first slide rail 22 and the second slide rail 311 can be various, as long as the sliding connection between the fixed body 31 and the mounting frame 2 can be realized. In order to ensure the stable sliding and positioning of the fixed body 31 in the mounting frame 2, the number of the first slide rails 22 can be four, and they can be distributed at the four corners of the mounting frame 2 along the length direction of the mounting frame 2. Similarly, the number of the second slide rails 311 can be four, and they can be distributed at the four corners of the fixed body 31 along the length direction of the fixed body 31.

[0054] In some examples, the second slide rail 311 can be a slide groove arranged along the length direction of the fixed body 31; and the first slide rail 22 can be a plurality of bearings rollingly set on the mounting frame 2 and arranged along the length direction of the mounting frame 2. The plurality of bearings are slidably connected with the slide groove, and the structure is simple and reliable.

[0055] For some examples, see Figure 1 The fixed body 31 of the battery fixing structure 3 may be provided with a charging interface 312, which is used to be electrically connected to the battery, so that when the battery needs to be charged, the charging interface 312 only needs to be electrically connected to the power interface to complete the charging of the battery without performing other operations, which is convenient to use. Specifically, the charging interface 312 can be provided at the end of the fixed body 31 to facilitate the connection between it and the power interface.

[0056] For some examples, see Figure 1 A handle 313 may also be provided at the end of the fixing body 31 so that an operator can pull out or push in the fixing body 31 through the handle 313 , thereby facilitating installation of the battery fixing structure 3 in the mounting frame 2 .

[0057] For some examples, see Figure 3 The battery fixing structure 3 may further include a connecting plate 32 disposed on the top surface of the fixing body 31; the second slide rail 311 is disposed on the connecting plate 32. By disposing the connecting plate 32, after the battery fixing structure 3 is installed on the mounting frame 2 of the fuselage 1, a certain gap can be formed between the fixing body 31 and other parts of the fuselage 1 to avoid interference between other parts of the fuselage 1 and the fixing body 31, thereby ensuring their respective work. In order to reduce weight and improve strength, the connecting plate 32 may be an "8"-shaped plate.

[0058] Since there may be other structures or parts on the fuselage 1 at the end of the mounting frame 2, the fixing body 31 of the battery fixing structure 3 is likely to interfere with the other structures or parts when sliding into or out of the mounting frame 2, resulting in the fixing body 31 being unable to slide in or out. In order to solve this problem, in some examples, see Figure 3 The mounting frame 2 has an open end 23 for the fixing body 31 to slide in or out of the interior thereof, and a connecting end 24 which is opposite to the open end 23 and can be rotatably connected to the fuselage 1; the UAV may further include a second locking portion, which has a locked state and an unlocked state; when the second locking portion is in the locked state, the mounting frame 2 can be locked to the fuselage 1; when the second locking portion is in the unlocked state, the open end 23 of the mounting frame 2 can be rotated relative to the fuselage 1 and lifted.

[0059] According to the above embodiment, since the connecting end of the mounting frame 2 is rotatably connected to the fuselage 1, the open end 23 of the mounting frame 2 can be lifted or lowered relative to the fuselage 1. Therefore, when the second locking portion is in the unlocked state, the open end 23 of the mounting frame 2 can be lifted and passed over other structures or components provided on the fuselage 1. At this time, the fixing body 31 can be slid in or out from the open end 23 of the mounting frame 2 to avoid interference. After the fixing body 31 slides into the mounting frame 2, the mounting frame 2 can be lowered and the second locking portion can be used to lock the mounting frame 2 on the fuselage 1 to complete the installation or removal of the battery, which is more convenient to use.

[0060] For some examples, see Figure 4 , and combined with Figure 3The mounting frame 2 may have a bottom plate 24; the second locking portion may include a rotating member 5 rotatably connected to the fuselage 1 and opposite to the end of the bottom plate 24; wherein the rotating member 5 can rotate to a first position and a second position relative to the fuselage 1, and when the rotating member 5 rotates to the first position, the rotating member 5 is pressed against the bottom plate 24 to form a locked state of the second locking portion; when the rotating member 5 rotates to the second position, the rotating member 5 is separated from the bottom plate 24 to form an unlocked state of the second locking portion.

[0061] According to the above embodiment, when it is necessary to install or remove the battery, the rotating member 5 can be rotated to the second position so that the rotating member 5 is separated from the bottom plate 24 of the mounting frame 2. At this time, the mounting frame 2 can be lifted. After the fixed body 31 containing the battery slides in or out of the mounting frame 2, the rotating member 5 can be rotated to the first position so that the rotating shoulder presses the bottom plate 24 of the mounting frame 2, thereby fixing the mounting frame 2 on the fuselage 1, which is more convenient to use.

[0062] For some examples, see Figure 4 , the other structures or parts that may exist on the fuselage 1 at the end of the mounting frame 2 mentioned above may be a step 11 protruding from the bottom plate 24 of the mounting frame 2 and opposite to the end of the bottom plate 24 of the mounting frame 2, that is, a carbon plate. One end of the rotating member 5 can be rotatably connected to the step 11 surface of the step 11, and the other end can protrude from the step 11 surface of the step 11, and is provided with a convex edge 51 extending toward the bottom plate 24, and the convex edge 51 can be arc-shaped; when the rotating member 5 rotates between the first position and the second position relative to the fuselage 1, the convex edge 51 can bypass the sharp corner of the step 11 to press against the bottom plate 24 or detach from the bottom plate 24. By setting the convex edge 51 of the rotating member 5 to an arc shape, it is convenient for it to bypass the step 11 to press against or detach from the bottom plate 24, and it is more convenient to use. Specifically, the number of the rotating member 5 can be two, and they are rotatably arranged side by side on the step 11 surface of the step 11.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
