[0004] This invention provides an unmanned aerial vehicle (UAV) to improve at least one of the aforementioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions.

[0006] This utility model provides a drone, including: The fuselage is connected to an arm assembly, the arm assembly is provided with a rotor assembly for providing power, the fuselage forms a battery compartment, and the battery compartment is provided with a mating part; A battery, which is detachably installed in the battery compartment, includes a housing and a power assembly disposed within the housing. The power assembly is used to provide power to the rotor assembly. The housing is provided with a latching member, which includes a cantilever portion, a fastening portion, and a pressing portion. The cantilever portion is connected between the housing and the fastening portion. When the battery is located in the battery compartment and pressure is applied to the pressing part, the cantilever part can undergo elastic deformation, causing the fastening part to separate from the mating part, so that the battery can be pulled out of the battery compartment; when the battery is located in the battery compartment and pressure is released on the pressing part, the fastening part can engage with the mating part to lock the battery in the battery compartment.

[0007] In one embodiment, the cantilever portion is integrally formed with the outer casing; In one embodiment, at least one of the cantilever portion, the fastening portion, or the pressing portion, together with the outer casing, constitutes the battery housing.

[0008] In one embodiment, the outer casing includes a first casing and a second casing, the second casing being detachably connected to the first casing, and the cantilever portion, the fastening portion, the pressing portion, the first casing, and the second casing together constitute the casing of the battery.

[0009] In one embodiment, the cantilever portion, the fastening portion, and the second housing are integrally formed. In another embodiment, the cantilever portion is made of plastic.

[0010] In one embodiment, the pressing part is spaced apart from the power supply component to provide movement space for the pressing part.

[0011] In one embodiment, the pressing part is provided with an anti-slip structure, which is located on the side of the pressing part away from the power supply component.

[0012] In one embodiment, the anti-slip structure includes a plurality of anti-slip protrusions arranged in an array.

[0013] In one embodiment, the drone further includes a GPS module located within the fuselage, the GPS module being spaced apart from the battery, and the outer shell having an electromagnetic reflective film disposed on the side of the outer shell facing the GPS module.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0028] The technical solutions of the embodiments of the utility model will now be clearly and completely described with reference to the accompanying drawings.

[0029] Please see Figure 1 This utility model proposes a drone 10, which can be a fixed-wing unmanned aircraft, a vertical take-off and landing unmanned aircraft, an unmanned airship, a multi-rotor unmanned aerial vehicle, an unmanned paraglider, etc. In the following embodiments, the drone 10 is a multi-rotor drone.

[0030] Please see Figure 1 , Figure 2 and Figure 5 The drone 10 includes a fuselage 100, a battery 200, and a latching member 300, which can be disposed on the outer shell of the battery 200. The fuselage 100 is connected to an arm assembly, which includes a rotor assembly for providing power. The fuselage 100 forms a battery compartment 110, which has a mating portion 120. The battery 200 is detachably installed in the battery compartment 110 and includes a housing 210 and a power assembly 220 disposed within the housing 210. The latching member 300 includes a cantilever portion 310, a fastening portion 320, and a pressing portion 330. The cantilever portion 310 is also connected between the housing 210 and the fastening portion 320. Exemplarily, the cantilever portion 310, the fastening portion 320, and the pressing portion 330 are connected sequentially; in other embodiments, the cantilever portion 310, the pressing portion 330, and the fastening portion 320 may also be connected sequentially. When the battery 200 is located inside the battery compartment 110 and pressure is applied to the pressing part 330, the cantilever part 310 can elastically deform, causing the fastening part 320 to separate from the engaging part 120, allowing the battery 200 to be pulled out of the battery compartment 110. When the battery 200 is located inside the battery compartment 110 and pressure is released on the pressing part 330, the fastening part 320 can engage with the engaging part 120 (e.g., a latch) to lock the battery 200 inside the battery compartment 110. Thus, when it is necessary to remove the battery 200, the user can apply force to the pressing part 330, causing the cantilever part 310 to elastically deform, separating the fastening part 320 from the engaging part 120, allowing the battery 200 to be pulled out of the battery compartment 110. The drone of this embodiment helps the user to pull the battery 200 out of the battery compartment 110 with less force.

[0031] When it is necessary to install the battery 200 into the battery compartment 110, the user can apply force to the pressing part 330, causing the cantilever part 310 to undergo elastic deformation. Then, the user inserts the battery 200 into the battery compartment 110. During this process, the fastening part 320 separates from the mating part 120. When the battery 200 moves to the appropriate position in the battery compartment 110 (the fastening part 320 can engage with the mating part 120), the user can release the force applied to the pressing part 330, so that the fastening part 320 can engage with the mating part 120, thereby locking the battery 200 in the battery compartment 110.

[0032] Please see Figures 3 to 5 In some embodiments, one of the fastening part 320 and the mating part 120 is a latching protrusion, and the other is a latching groove. When the battery 200 is located in the battery compartment 110, the latching protrusion is embedded in the latching groove. Thus, the fastening part 320 and the mating part 120 use a latching protrusion and a latching groove mating method, which is not only simple in structure and easy to manufacture, but also enables quick and accurate fixing of the battery 200 to the body 100. In other embodiments, the fastening part 320 is a hook, and the mating part 120 is adapted to the hook to form a detachable structure.

[0033] In some embodiments, the battery compartment 110 also has an opening 180 for inserting the battery 200 into the battery compartment 110 along its length.

[0034] In some embodiments, there may be multiple fasteners 300, which may be disposed on opposite sides of the housing 210. For example, there may be two fasteners 300.

[0035] Please see Figure 4 and Figure 5 In some embodiments, the cantilever portion 310 and the outer shell 210 are integrally molded, which not only helps to improve the strength of the connection between the cantilever portion 310 and the outer shell 210, but also helps to reduce the assembly steps of the cantilever portion 310 and the outer shell 210. Furthermore, the integral molding of the cantilever portion 310 and the outer shell 210 eliminates the need for additional connectors, thereby helping to reduce the overall weight of the drone 10. Exemplarily, the cantilever portion, the fastening portion, and the pressing portion are all made of plastic to reduce the weight of the drone. Exemplarily, the pressing portion is spaced apart from the power assembly to provide movement space for the pressing portion.

[0036] In some embodiments, at least one of the cantilever portion 310, the fastening portion 320, or the pressing portion 330, together with the outer casing 210, constitutes the housing 260 of the battery 200. The housing 260 can enclose the power assembly 220 to protect it. Thus, at least one of the fastening portion 320 or the pressing portion 330 does not need to be stacked with the outer casing 210. Effectively utilizing at least one of the cantilever portion 310, the fastening portion 320, or the pressing portion 330 of the latching member 300 as part of the housing 260 helps reduce the manufacturing material of the housing 260, thereby contributing to a reduction in the overall weight of the drone 10.

[0037] Please see Figures 5 to 7 In some embodiments, the housing 210 includes a first housing 211 and a second housing 212, with the second housing 212 detachably connected to the first housing 211. For example, the second housing 212 can be connected to the first housing 211 via a snap-fit ​​connection or a plug-in connection. This allows the operator to easily disassemble the second housing 212 and the first housing 211, facilitating the installation of the power supply assembly 220 within the housing 210. Furthermore, the user can disassemble the second housing 212 from the first housing 211, facilitating cleaning of the power supply assembly 220.

[0038] Please see Figure 6 and Figure 8 The cantilever portion 310, the fastening portion 320, the pressing portion 330, the first housing 211, and the second housing 212 together constitute the housing 260 of the battery 200, so that the fastener 300 does not need to be stacked with the first housing 211 or the second housing 212. The fastener 300 is effectively used as part of the housing 260, which helps to reduce the manufacturing material of the housing 260 and further helps to reduce the weight of the entire drone 10.

[0039] Please see Figure 8 In some embodiments, the cantilever portion 310, the fastening portion 320, and the second housing 212 are integrally formed. This not only helps to reduce the assembly process of the cantilever portion 310, the fastening portion 320, and the second housing 212, but also helps to improve the strength of the connection between the cantilever portion 310 and the fastening portion 320, as well as the strength of the connection between the cantilever portion 310 and the second housing 212.

[0040] Please see Figure 6 and Figure 8In some embodiments, the cantilever portion 310 is a plastic cantilever portion, allowing it to undergo elastic deformation. Since one end of the cantilever portion 310 is connected to the outer casing 310 and the other end is connected to the fastening portion 320, when the pressing portion 330 moves, it can move the cantilever portion 310. When the battery 200 is located inside the battery compartment 110 and pressure is applied to the pressing portion 330, the pressing portion 330 can move the cantilever portion 310, causing it to deform and change the position of the fastening portion 320. This allows the fastening portion 320 to separate from the mating portion 120, thereby allowing the battery 200 to be pulled out of the battery compartment 110. When the battery 200 is located in the battery compartment 110 and the pressing force on the pressing part 330 is released, the cantilever part 310 needs to return to its original shape to change the position of the fastening part 320, so that the fastening part 320 engages with the mating part 120, thereby locking the battery 200 in the battery compartment 110. In other embodiments, the cantilever part 310 may also be an aluminum alloy cantilever part or an iron metal cantilever part, etc.

[0041] Please see Figures 7 to 9 In some embodiments, the pressing part 330 is spaced apart from the power supply assembly 220 to provide movement space for the pressing part, so that the pressing part 330 has a displacement, thereby enabling the pressing part 330 to drive the cantilever part 310 to move, which in turn helps the cantilever part 310 to deform and return to its original shape.

[0042] In some embodiments, the mating part is disposed on the inner wall of the battery compartment so that when the battery is located in the battery compartment, neither the fastening part nor the mating part is exposed, thereby avoiding damage to the fastening part.

[0043] Please see Figure 5 In some embodiments, the pressing part 330 is provided with an anti-slip structure 340, which is located on the side of the pressing part 330 opposite to the power assembly 220. The anti-slip structure 340 may be a series of tiny protrusions; alternatively, it may be an anti-slip pad made of soft rubber or silicone material. When the user presses the pressing part 330, the user's hand contacts the anti-slip structure 340, helping to reduce the risk of the user's hand slipping on the pressing part 330.

[0044] In some embodiments, the anti-slip structure 340 includes a plurality of anti-slip protrusions 341 arranged in an array. Thus, the regular arrangement of the plurality of anti-slip protrusions 341 forms a dense anti-slip structure 340, which helps to increase the friction between the user's hand and the pressing part 330, and the structure is simple and easy to manufacture.

[0045] In some embodiments, the drone 10 also includes a GPS module 400 located within the fuselage 100, spaced apart from the battery 200. The outer shell 210 is provided with an electromagnetic reflective film 250, located on the side of the outer shell 210 facing the GPS module 400. Specifically, when the drone 10 is in flight, the GPS module 400 can be positioned above the battery 200. The electromagnetic reflective film 250 can reflect electromagnetic signals. Since the electromagnetic reflective film 250 is located on the side of the battery 200 facing the GPS module 400 of the drone 10, it can reflect a portion of the GPS signal back to the GPS module 400, thereby enhancing the GPS signal received by the GPS module 400.

[0046] In addition, the electromagnetic reflective film 250 can not only concentrate and enhance the gain of the GPS antenna of the GPS module 400 in a specific direction, but also effectively reduce interference from other directions (such as the battery and control board), thereby helping the GPS module 400 of the UAV 10 to obtain positioning information more accurately and stably.

[0047] In this embodiment, the electromagnetic reflective film 250 can be a metal dielectric reflective film. For example, the metal dielectric reflective film can include a metal film and a dielectric layer, with the dielectric layer disposed on the outer side of the metal film (i.e., the side of the metal film facing away from the battery 200). The metal film can be made of at least one of aluminum, gold, silver, and copper, and the dielectric layer can be made of at least one of silicon monoxide, magnesium fluoride, silicon dioxide, and aluminum oxide.

[0048] Please see Figure 4 , Figure 6 and Figure 7 In some embodiments, the housing 210 is provided with heat dissipation holes 240, and the power assembly 220 is exposed through the heat dissipation holes 240, so that the power assembly 220 can exchange heat with the air through the heat dissipation holes 240. This allows the heat generated by the power assembly 220 during operation to be directly exchanged with the outside air, thereby enabling the power assembly 220 to operate within a suitable operating temperature range, which in turn helps to extend the service life of the battery 200 and ensure the flight performance of the UAV 10.

[0049] Please see Figure 3 and Figure 6In some embodiments, the battery compartment 110 is provided with a first guide portion 130, and the outer casing 210 is provided with a second guide portion 230, which can guide and cooperate with the first guide portion 130. The second guide portion 230 can extend along the length of the battery 200, and the first guide portion 130 can extend along the length of the battery compartment 110. Because the second guide portion 230 can guide and cooperate with the first guide portion 130, the battery 200 fastening portion 320 can quickly and accurately engage and securely fasten with the body 100 fastening portion 320. The user only needs to gently push the battery 200 along the first guide portion 130, and the battery 200 will automatically align and securely fasten into the body 100 without additional manual adjustment or correction. This helps reduce the risk of installation difficulties or poor contact due to misalignment. In some embodiments, one of the first guide portion 130 and the second guide portion 230 is a guide rib, and the other is a guide groove. When the battery 200 is located in the battery compartment 110, the guide rib is embedded in the guide groove. Specifically, the first guide portion 130 can be a guide rib, and correspondingly, the second guide portion 230 can be a guide groove. When the battery 200 is located in the battery compartment 110, the first guide portion 130 is embedded in the second guide portion 230; or, the first guide portion 130 can be a guide groove, and correspondingly, the second guide portion 230 can be a guide rib. When the battery 200 is located in the battery compartment 110, the second guide portion 230 is embedded in the first guide portion 130. In this way, the first guide portion 130 and the second guide portion 230 adopt a combination of guide rib and guide groove, which not only has a simple structure and is easy to manufacture, but also enables fast and accurate guidance between the battery 200 and the body 100.

[0050] In addition, the first guide portion 130 and the second guide portion 230 help the battery 200 slide into the battery compartment 110 along the length direction of the battery compartment 110 until it reaches the preset installation position. At the same time, they help reduce the risk of the battery 200 shifting or misaligning during the insertion process, thereby helping the fastening portion 320 to accurately engage and fix with the mating portion 120.

[0051] Please see 1 and Figure 2In some embodiments, the fuselage 100 may include a middle frame 150, a top cover 160, and a bottom cover 170. The middle frame 150 may be connected between the top cover 160 and the bottom cover 170. The middle frame 150 is provided with a battery compartment 110, a fuselage 100 fastening part 320, and a first guide part 130. The battery compartment 110 extends along the length direction of the middle frame 150. Specifically, the top cover 160 may be located above the middle frame 150, and the bottom cover 170 may be located below the middle frame 150, so that the middle frame 150 is approximately located in the middle of the drone 10. This allows the battery 200 installed in the middle frame 150 to balance the weight of the drone 10, thereby helping the drone 10 maintain a stable center of gravity during flight.

[0052] In addition, the battery 200 is installed in the battery compartment 110 of the mid-frame 150, which is roughly located in the middle of the drone 10. This helps to balance the front and rear weight of the drone 10, reduce the energy consumption required by the drone 10 in the process of adjusting its flight attitude, and also helps to improve the control response speed and flexibility of the drone 10 in complex flight environments.
