In addition, the two ends of the battery casing extend through channels in the center of the fuselage and maintain balance, which can play a role similar to wings or a balance beam, further increasing the stability of the drone's flight.

Description

Technical Field

[0001] This utility model relates to the field of drone battery technology, and more specifically, to a drone battery mounting structure. Background Technology

[0002] In existing technology, some commercially available performance drones have a battery mounting structure integrated with the fuselage, which is not detachable. In this case, the drone's battery capacity and usage time are fixed. Once the battery is depleted, it needs to be fully charged before it can be used again. Replacing the battery cannot extend the drone's usage time, which significantly limits its usability.

[0003] Some drones use a separate battery casing structure, allowing for convenient battery replacement when needed. However, this entire battery casing structure is housed within the fuselage, occupying significant internal space. To accommodate other components, the fuselage structure must be enlarged, leading to increased overall weight, higher power consumption, and reduced flight range. Furthermore, the battery casing structure is typically inserted from the side or tail, causing a shift in the center of gravity, which can affect the drone's stability and flight performance. For example, some drones have their battery casing structure inserted from the tail end, resulting in a heavier weight at the tail end and a shifted center of gravity towards that area.

[0004] CN217554185U discloses a drone battery compartment, characterized by comprising a battery compartment body (1), a battery compartment cover (2), a lifting block (7), and a locking mechanism. The lifting block (7) is located at the bottom of the battery compartment body (1) to facilitate the extraction of the drone battery. The locking mechanism is located on one inner side of the battery compartment body (1), and a fixing mechanism is also provided on the outer side of the battery compartment body (1) to further secure the battery compartment cover (2). Its simple structural design achieves both rapid battery replacement and effective battery protection, preventing the battery from detaching during impact and causing damage to the drone battery.

[0005] However, the drone still has its battery compartment and battery installed inside the fuselage, occupying a significant amount of internal space and hindering its lightweight and miniaturization. Furthermore, the battery is inserted from the rear end, resulting in a heavier weight at the rear and a center of gravity towards the rear. While this battery installation structure allows for quick battery replacement, it still requires opening the compartment cover, removing the battery structure from inside the fuselage, replacing the battery, and then reinstalling the battery structure before closing the compartment cover.

[0006] Furthermore, when new battery technologies or higher-performance batteries emerge, the battery compartment structure may limit their compatibility, making it difficult to upgrade the drone's battery system. Moreover, the battery management system is located inside the drone's fuselage; when related circuits, parts, or components fail, the entire drone must be disassembled for repair. This increases the difficulty and time required for assembly, hindering rapid maintenance and repair. Utility Model Content

[0007] The present invention aims to solve the above-mentioned technical problems to at least a certain extent.

[0008] The purpose of this invention is to provide a drone battery installation structure that facilitates battery replacement and occupies less internal space.

[0009] The technical solution adopted by this utility model to solve its technical problem is: a UAV battery mounting structure, comprising: The fuselage has through channels on both sides of its center. A battery compartment, which covers and is installed on the inner wall of the through channel and forms the through channel, and the battery compartment is provided with a slot; The battery casing has an internal cavity, the battery casing is shaped to match the battery compartment, both ends of the battery casing can extend through channels, and one side of the battery casing has a first fixing groove. A spring-loaded latching mechanism is provided in a first fixed groove. The spring-loaded latching mechanism includes a latch and a spring. The latch is fixed to the spring, and the latch can be engaged or disengaged from the groove by the spring.

[0010] In use, the battery is stored in the receiving cavity of the battery case. When installing the battery case, pressing the latch compresses the spring, causing the latch to retract into the first fixing groove. The battery case is then inserted into the battery compartment, with both ends extending through the channels to maintain overall balance. When the battery case reaches the designated installation position, releasing the latch causes the spring to return, popping the latch out and engaging with the groove to lock the battery compartment in place. To replace the battery, pressing the latch again compresses the spring, causing the latch to retract into the first fixing groove, thus unlocking the battery case. The battery case can then be removed from the battery compartment for battery replacement; after removal, the latch can be released.

[0011] This invention features through-channels on both sides of the fuselage, with the battery casing's ends extending out of these channels, rather than being entirely within the fuselage. This results in a smaller footprint within the drone's internal space for the same battery weight, eliminating the need to increase the fuselage's structural dimensions and reducing the overall weight. Furthermore, the center of gravity is located at the drone's center, preventing shifts and improving stability and flight performance. Additionally, the battery casing's ends extending out of the through-channels at the center of the fuselage and maintaining balance function similarly to wings or a balancing beam, further enhancing the drone's flight stability.

[0012] This invention enables quick assembly and disassembly of the battery casing via a spring-loaded latch mechanism, eliminating the need to access the internal components. Because it is a separate battery casing, the layout of the housing can be easily adjusted to accommodate new battery technologies or higher-performance batteries, facilitating battery replacement. Furthermore, the battery management system is located within this separate casing; any damage to related circuitry, parts, or components can be quickly maintained and repaired simply by opening the casing.

[0013] In a preferred embodiment, the battery compartment includes an upper battery compartment shell and a lower battery compartment shell. The upper and lower battery compartment shells are respectively provided with stud holes and fixed to the upper and lower sides of the through-channel by fastening screws, together forming the inner wall of the through-channel. Since the through-channel is located inside the fuselage, it is not conducive to the installation of the overall component structure. Therefore, splitting the battery compartment into an upper and lower battery compartment shell facilitates the installation and fixing of the battery compartment. Furthermore, the columnar structure of the stud holes is preferably distributed around the perimeter, which can be used for installation and fixing, and also increases the overall strength of the structure.

[0014] More preferably, the inner wall of the through channel is provided with multiple raised ribs along the direction of the through channel. The presence of multiple raised ribs along the direction of the through channel helps increase the friction between the battery casing and the battery compartment and improves stability after installation, preventing excessive gaps that could cause wobbling. Furthermore, the multiple raised ribs further increase the overall structural strength of the battery compartment, which is beneficial for long-term use.

[0015] In a preferred embodiment, the battery casing includes an upper battery casing and a lower battery casing, which together form a receiving cavity. Dividing the battery casing into an upper and lower casing facilitates the installation of multiple batteries and allows for opening the casing to observe the battery's condition.

[0016] More preferably, the receiving cavity is provided with dividing strips in both the horizontal and vertical directions, dividing the receiving cavity into multiple receiving slots, each receiving slot having multiple arc-shaped ribs. These multiple receiving slots are used to install multiple batteries respectively, allowing each battery to be installed in its own individual slot, resulting in a more stable installation, especially preventing shaking during flight. The arc-shaped ribs match the arc shape of the battery, further enhancing battery stability. The dividing strips and multiple arc-shaped ribs also increase the overall structural strength of the battery casing, contributing to long-term use.

[0017] More preferably, the receiving cavity is provided with a second fixing slot, and the second fixing slot is provided with a power display screen. The second fixing slot can be used to install and fix battery power detection components or modules, and the power display screen can display the remaining battery power for user convenience.

[0018] In a preferred embodiment, the latch includes a latching part and a pressing part. The latching part is located at the end near the slot, and the pressing part is located at the end away from the slot. The pressing part causes the latching part to engage or disengage from the slot. When installing the battery case, pressing the pressing part compresses the spring, and the entire latching part retracts into the first fixing groove. When the battery case is inserted into the battery compartment and reaches the designated installation position, releasing the pressing part causes the spring to return, and the latching part pops out, engaging with the slot and locking the battery compartment, thereby securing the battery case to the battery compartment and achieving a locked state. When the battery needs to be replaced, pressing the pressing part again compresses the spring, and the latching part retracts into the first fixing groove, thereby achieving an unlocked state.

[0019] The beneficial effects of this utility model are: This invention features through-channels on both sides of the fuselage, with the battery casing's ends extending out of these channels, rather than being entirely within the fuselage. This results in a smaller footprint within the drone's internal space for the same battery weight, eliminating the need to increase the fuselage's structural dimensions and reducing the overall weight. Furthermore, the center of gravity is located at the drone's center, preventing shifts and improving stability and flight performance. Additionally, the battery casing's ends extending out of the through-channels at the center of the fuselage and maintaining balance function similarly to wings or a balancing beam, further enhancing the drone's flight stability.

[0020] This invention enables quick assembly and disassembly of the battery casing via a spring-loaded latch mechanism, eliminating the need to access the internal components. Because it is a separate battery casing, the layout of the housing can be easily adjusted to accommodate new battery technologies or higher-performance batteries, facilitating battery replacement. Furthermore, the battery management system is located within this separate casing; any damage to related circuitry, parts, or components can be quickly maintained and repaired simply by opening the casing.

[0029] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the present invention. To better illustrate the embodiments, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 8 As shown, a UAV battery mounting structure 100 of this utility model includes: a fuselage 101, a battery compartment 102, a battery shell 103, and a spring latching mechanism 104.

[0032] The body 101 has through channels 105 in the center of both sides, and the battery compartment 102 is installed on the through channels 105 and forms the inner wall of the through channels 105.

[0033] In this embodiment, the battery compartment 102 includes an upper battery compartment shell 106 and a lower battery compartment shell 107. The upper and lower battery compartment shells 106 and 107 are respectively provided with stud holes 108 and are fixed to the upper and lower sides of the through channel 105 by fastening screws, forming the inner wall of the through channel 105. Since the through channel 105 is located inside the body 101, it is not conducive to the installation of the overall component structure. Therefore, the battery compartment 102 is divided into the upper battery compartment shell 106 and the lower battery compartment shell 107 to facilitate the installation and fixing of the battery compartment 102. Furthermore, the columnar structure of the stud holes 108 is preferably distributed around the perimeter, which can be used for installation and fixing, and also increases the overall strength of the structure.

[0034] In this embodiment, the inner wall of the through channel 105 is provided with multiple raised ribs 109 along the direction of the through channel 105. The presence of multiple raised ribs 109 along the direction of the through channel 105 helps increase the friction between the battery casing 103 and the battery compartment 102 and improves stability after installation, preventing excessive gaps that could cause wobbling. Furthermore, the multiple raised ribs 109 further increase the overall structural strength of the battery compartment 102, which is beneficial for long-term use.

[0035] The battery housing 103 has an internal cavity, the battery housing 103 is shaped to match the battery compartment 102, both ends of the battery housing 103 can extend through the through channel 105, and a first fixing groove 110 is provided on one side of the battery housing 103.

[0036] In this embodiment, the battery casing 103 includes an upper battery casing 111 and a lower battery casing 112, which together form a receiving cavity. Dividing the battery casing 103 into the upper battery casing 111 and the lower battery casing 112 facilitates the installation of multiple batteries and allows for opening the battery casing 103 to observe the battery's usage.

[0037] In this embodiment, the receiving cavity is provided with dividing strips 113 in both the horizontal and vertical directions, dividing the receiving cavity into multiple receiving slots 114. Each receiving slot 114 is provided with multiple arc-shaped ribs 115. The multiple receiving slots 114 are used to install multiple batteries respectively, allowing each battery to be installed in its own individual slot 114, resulting in a more stable installation, especially preventing shaking during flight. The arc-shaped ribs 115 match the arc shape of the battery, further enhancing battery stability. The dividing strips 113 and the multiple arc-shaped ribs 115 also increase the overall structural strength of the battery casing 103, which is beneficial for long-term use.

[0038] In this embodiment, the receiving cavity is provided with a second fixing slot 116, and the second fixing slot 116 is provided with a power display screen 117. The second fixing slot 116 can be used to install and fix battery power detection components or modules, and the remaining battery power is displayed on the power display screen 117 for user convenience.

[0039] The battery compartment 102 is provided with a slot 118, and the spring buckle mechanism 104 is provided in the first fixing slot 110. The spring buckle mechanism 104 includes a buckle 119 and a spring 120. The buckle 119 is fixed to the spring 120, and the buckle 119 can be engaged or disengaged from the slot 118 by means of the spring 120.

[0040] In use, the battery is stored in the receiving cavity of the battery case 103. When installing the battery case 103, pressing the buckle 119 compresses the spring 120, causing the buckle 119 to retract into the first fixing groove 110. The battery case 103 is then inserted into the battery compartment 102, with both ends of the battery case 103 extending through the through-channel 105 to maintain overall balance. When the battery case 103 reaches the designated installation position, releasing the buckle 119 causes the spring 120 to return, and the buckle 119 pops out, engaging with the locking groove 118 to secure the battery compartment 102, thus locking the battery case 103 to the battery compartment 102. When the battery needs to be replaced, pressing the buckle 119 again compresses the spring 120, causing it to retract into the first fixing groove 110, thus unlocking the battery case 103. This allows the battery case 103 to be removed from the battery compartment 102 for battery replacement; after removal, the buckle 119 can be released.

[0041] In this embodiment, the latch 119 includes a latching part 121 and a pressing part 122. The latching part 121 is located at the end near the slot 118, and the pressing part 122 is located at the end away from the slot 118. The pressing part 122 drives the latching part 121 to engage or disengage from the slot 118. When installing the battery case 103, pressing the pressing part 122 compresses the spring 120, and the entire latching part 121 retracts into the first fixing groove 110. When the battery case 103 is installed into the battery compartment 102, and the battery case 103 reaches the designated installation position, the pressing part 122 is released, the spring 120 rebounds, and the latching part 121 is ejected, just engaging with the slot 118 and locking the battery compartment, thereby fixing the battery case 103 to the battery compartment 102 and achieving a locked state. When the battery needs to be replaced, press the pressing part 122 again, the spring 120 is compressed, and the latch part 121 retracts into the first fixing groove 110, thereby achieving the unlocked state.

[0042] In summary, this invention features through-channels 105 at the center of both sides of the fuselage 101, with both ends of the battery casing 103 extending out of these channels, rather than being entirely contained within the fuselage 101. This results in a smaller footprint within the drone's internal space for the same battery weight, eliminating the need to increase the structural dimensions of the fuselage 101 and reducing the overall weight of the drone. Furthermore, the center of gravity is located at the center of the drone, preventing center-of-gravity shift and improving the drone's stability and flight performance. Additionally, the two ends of the battery casing 103 extending out of the through-channels 105 at the center of the fuselage 101 and maintaining balance function similarly to wings or a balance beam, further enhancing the drone's flight stability.

[0043] This invention enables quick assembly and disassembly of the battery casing 103 via a spring-loaded latch mechanism 104, without requiring access to the internal components. Because the battery casing 103 is a separate unit, the layout of the housing can be easily adjusted to accommodate new battery shapes or models, facilitating battery replacement. Furthermore, the battery management system is located within the separately structured battery casing 103; any damage to related circuitry, parts, or components can be quickly addressed by simply disassembling the battery casing 103.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
