[0005] The body structure according to the embodiments of this application has at least the following beneficial effects: by setting a shell, the battery is placed inside the shell, thereby protecting the battery and preventing the exposed battery from being accidentally damaged by collision during the use of the drone, thus increasing maintenance costs. The setting of the battery assembly facilitates the provision of power to the various modules connected to the body. The setting of the first limiting part on the shell and the second limiting part on the battery facilitates the rotation of the second limiting part towards the first limiting part when the battery is completely placed in the cavity, so that the second limiting part is engaged with the first limiting part to prevent the battery from detaching from the cavity, thereby reducing the risk of damage to the battery due to detachment from the cavity and reducing production costs. When it is necessary to remove the battery, the second limiting part can be rotated away from the first limiting part, so that the second limiting part is disengaged from the first limiting part, allowing the battery to be smoothly detached from the cavity. This simplifies the battery installation and removal process and improves the efficiency of body assembly or disassembly.

[0006] According to some embodiments of this application, a guide assembly is provided circumferentially on the inner sidewall of the cavity, the guide assembly being used to guide the battery to slide into the cavity.

[0015] The body structure of the first aspect of this application.

[0016] The drone according to the embodiments of this application has at least the following beneficial effects: by setting a shell to place the battery inside the shell, the battery is protected, avoiding accidental damage to the exposed battery due to collision during drone use, thus reducing maintenance costs. The battery assembly facilitates the provision of power to the various modules connected to the body. The setting of the first limiting part on the shell and the second limiting part on the battery facilitates the rotation of the second limiting part towards the first limiting part when the battery is completely placed in the cavity, so that the second limiting part engages with the first limiting part to prevent the battery from detaching from the cavity, thereby reducing the risk of damage to the battery due to detachment from the cavity and reducing production costs. When it is necessary to remove the battery, the second limiting part can be rotated away from the first limiting part, so that the second limiting part is disengaged from the first limiting part, allowing the battery to be smoothly removed from the cavity. This simplifies the battery installation and removal process and improves the efficiency of body assembly or disassembly. By introducing the body structure of this application, the efficiency of drone assembly and disassembly of this application is improved, thereby reducing the time cost required for production.

[0028] Currently, traditional drone batteries and battery compartments are often connected through cumbersome detachable structures, making the disassembly and installation of batteries and battery compartments quite complicated. This results in longer assembly or disassembly times for the drone and higher production time costs. In addition, some drones have short flight times and often require frequent battery replacements or removal for charging. The cumbersome disassembly and installation of batteries and battery compartments also affects the user's actual experience.

[0029] Based on this, this application proposes an airframe structure and a drone that can simplify the installation and disassembly process of the battery 110 and the battery compartment, and improve the assembly or disassembly efficiency of the airframe.

[0030] It is understood that the body structure of this application embodiment includes a housing 100 and a battery assembly. The housing 100 has an opening and a chamber 101 is provided inside the housing 100. The chamber 101 communicates with the outside of the housing 100 through the opening. A first limiting part 102 is provided at one end of the housing 100 with the opening. The battery assembly includes a battery 110 and a second limiting part 111. The battery 110 is disposed in the chamber 101. The second limiting part 111 is movably disposed at one end of the battery 110 near the opening. When the second limiting part 111 rotates toward the first limiting part 102, it engages with the first limiting part 102 to prevent the battery 110 from detaching from the housing 100. When the second limiting part 111 rotates away from the first limiting part 102, it releases the engagement with the first limiting part 102 so that the battery 110 can detach from the housing 100.

[0031] The beneficial effects of the body structure in this application embodiment are as follows: By providing a housing 100, the battery 110 is placed inside the housing 100, thereby protecting the battery 110 and preventing accidental damage to the exposed battery 110 due to collisions during drone use, thus reducing maintenance costs. The battery assembly facilitates the provision of power to the various modules connected to the body. The first limiting part 102 on the housing 100 and the second limiting part 111 on the battery 110 facilitate the rotation of the second limiting part 111 towards the first limiting part 102 when the battery 110 is completely placed inside the chamber 101. 1. This allows the second limiting part 111 to engage with the first limiting part 102, preventing the battery 110 from detaching from the chamber 101. This reduces the risk of damage to the battery 110 due to detachment from the chamber 101 and lowers production costs. When it is necessary to remove the battery 110, the second limiting part 111 can be rotated away from the first limiting part 102, causing the second limiting part 111 to disengage from the first limiting part 102, allowing the battery 110 to detach smoothly from the chamber 101. This simplifies the process of installing and removing the battery 110 and improves the efficiency of assembling or disassembling the machine body.

[0032] For example, in some embodiments, reference is made to Figure 1 and Figure 3In this embodiment, the housing 100 has a chamber 101 for accommodating the battery 110. The chamber 101 communicates with the outside through an opening on one side of the housing 100, so that the battery 110 can be placed into the chamber 101 through the opening. The housing 100 is designed to protect the battery assembly and prevent the battery 110 from being exposed and accidentally damaged during use. The second limiting part 111 is movably connected to the battery 110 through the first connecting member, that is, the second limiting part 111 can move in an arc around the first connecting member. The side wall of the housing 100 with the opening has a first limiting part 102 that matches the second limiting part 111. The second limiting part 111 includes a connecting plate 1111, a column 1112, and a limiting cover 1113. One end of the connecting plate 1111 is movably connected to the battery 110 via a first connector. One end of the column 1112 is fixedly connected to the limiting cover 1113, and the end of the column 1112 away from the limiting cover 1113 is fixedly connected to the other end of the connecting plate 1111. When the battery 110 needs to be limited after being placed into the chamber 101, the connecting plate 1111 is rotated. That is, the connecting plate 1111 rotates the column 1112 towards the first limiting part 102 with the first connector as the center, until the outer wall of the column 1112 is in contact with the first limiting part 102. At this point, the first limiting part 102 and the second limiting part 111 are in a locked connection. When the battery 110 tends to detach from the chamber 101, the outer wall of the column 1112 applies pressure to the first limiting part 102 in a direction away from the chamber 101, while the first limiting part 102 applies a reaction force to the outer wall of the column 1112 in a direction closer to the chamber 101, thereby confining the battery 110 within the chamber 101 and preventing the battery 110 from detaching from the chamber 101. The cross-sectional area of ​​the limiting cover 1113 is larger than the cross-sectional area of ​​the column 1112. The limiting cover 1113 is provided to prevent the first limiting part 102 from engaging with the column 1112. When the outer walls of the two parts abut and engage, the first limiting part 102 slides out along the axial direction of the column 1112, thus affecting the engagement effect. When it is necessary to remove the battery 110, the connecting plate 1111 is rotated in the opposite direction. That is, the connecting plate 1111 rotates away from the first limiting part 102 with the first connecting member as the center. In other words, the engagement state between the first limiting part 102 and the second limiting part 111 is released. At this time, the battery 110 can be smoothly removed from the chamber 101. It can be seen that the process of disassembling and installing the battery 110 in this application is simpler than the traditional battery 110 installation and disassembly, thus improving the efficiency of assembly or disassembly of the body.

[0033] It should be noted that the size of the chamber 101 is adapted to the size of the battery 110, that is, the chamber 101 can just accommodate the battery 110. When the first limiting part 102 and the second limiting part 111 are in the engaging state, the first limiting part 102 can more tightly abut against the outer wall of the column 1112. This not only prevents the battery 110 from detaching from the chamber 101, but also fixes the position of the battery 110 in the chamber 101, preventing the battery 110 from shaking in the chamber 101 during use and causing damage to the battery 110.

[0034] It is understandable that a guide assembly is provided circumferentially on the inner wall of chamber 101, and the guide assembly is used to guide the battery 110 to slide into chamber 101.

[0035] For example, in some embodiments, reference is made to Figure 1 In this embodiment, the guiding component includes guide wheels 106, which are located on opposite sides of the inner wall of the chamber 101 in a circumferential direction, so as to guide the battery 110 to slide into or out of the chamber 101 more quickly, thereby further improving the efficiency of the assembly of the body.

[0036] It is understood that the body structure of this application also includes a side cover 120, which is detachably fitted onto the opening.

[0037] For example, in some embodiments, reference is made to Figure 1 and Figure 2 In this embodiment, the side cover 120 is detachably closed onto the opening, thereby providing a certain degree of protection for the battery 110 located in the chamber 101 and preventing impurities or particles from entering the chamber 101 and damaging the battery 110.

[0038] It should be noted that before the side cover 120 is closed with the opening, the battery handle 112 needs to be rotated to fit against the battery 110.

[0039] It is understandable that the battery 110 is also provided with a battery handle 112 on the side near the side cover 120. The battery handle 112 is connected to the second limiting part 111 through the first connector. The battery handle 112 can move in an arc with the first connector as the center.

[0040] For example, in some embodiments, reference is made to Figure 1 and Figure 2In this embodiment, the battery handle 112 is located at one end of the battery 110 near the side cover 120, so that the battery 110 can be removed from the housing 100 more quickly by using the battery handle 112, further improving the efficiency of disassembly. The battery handle 112 can also move in an arc around the first connector, which facilitates rotation of the battery handle 112 towards the battery 110 after the battery 110 is installed in the chamber 101, causing the battery handle 112 to fit against the battery 110 and avoiding interference with the installation of subsequent components. Two second limiting parts 111 are provided, located on opposite sides of the battery 110. The two ends of the battery handle 112 are respectively connected to the two second limiting parts 111, making the connection of the battery handle 112 more secure.

[0041] It is understood that: the side cover 120 is provided with a third limiting part 122, and the periphery of the housing 100 is provided with a groove 104 at one end near the opening. The groove 104 is provided with a fourth limiting part 103 corresponding to the third limiting part 122. The third limiting part 122 and the fourth limiting part 103 are used to detachably connect the side cover 120 and the housing 100.

[0042] For example, in some embodiments, reference is made to Figure 1 and Figure 2 In this embodiment, the side cover 120 is provided with a third limiting part 122 on each of its opposite sides. The third limiting part 122 is movably connected to the side cover 120 through a second connector. The periphery of the housing 100 is provided with grooves 104 on each of its opposite sides near the opening. The third limiting part 122 and the groove 104 correspond one-to-one. The groove 104 is provided with a fourth limiting part 103 corresponding to the third limiting part 122. The groove 104 provides a certain degree of protection for the fourth limiting part 103, preventing the fourth limiting part 103 from being exposed outside the housing 100 and deformed due to impact, which would prevent the fourth limiting part 103 from continuing to be fastened to the third limiting part 122, thus increasing the maintenance cost of the product. The side cover 120 is detachably closed to the opening through the third limiting part 122 and the fourth limiting part 103. When the side cover 120 is closed, the third limiting part 122 moves in an arc with the second connector as the center towards the housing 100 until the third limiting part 122 and the fourth limiting part 103 are engaged. When the side cover 120 is removed, the third limiting part 122 moves in an arc with the second connector as the center away from the housing 100 to release the engagement between the third limiting part 122 and the fourth limiting part 103 so that the side cover 120 can be removed.

[0043] Furthermore, in some embodiments, the side cover 120 is also provided with a hinge structure. The third limiting part 122 is connected to the side cover through the hinge structure so that when the third limiting part 122 and the fourth limiting part 103 are engaged, the housing 100 is connected to the side cover 120 through the hinge structure. When the side cover 120 releases the engagement state of the third limiting part 122 and the fourth limiting part 103 on one side, the hinge structure can also drive the side cover 120 to make an arc movement away from the opening with the structure of the third limiting part 122 and the fourth limiting part 103 on the other side being engaged with each other as the center. This makes the process of opening or closing the side cover 120 easier and further improves the efficiency of disassembly or assembly of the machine body.

[0044] It is understandable that the side cover 120 is provided with multiple heat dissipation holes 121, which are used to connect the outside of the housing 100 with the cavity 101.

[0045] For example, in some embodiments, reference is made to Figure 1 and Figure 2 In this embodiment, the side cover 120 is provided with a plurality of heat dissipation holes 121 to connect the chamber 101 with the outside of the housing 100, thereby ensuring the air circulation and heat dissipation in the chamber 101 and avoiding excessive temperature in the chamber 101 from affecting the normal performance of the battery 110.

[0046] It is understood that the groove 104 is a trapezoidal groove 104, which is used to guide the connection between the third limiting part 122 and the fourth limiting part 103.

[0047] For example, in some embodiments, reference is made to Figure 1 and Figure 2 In this embodiment, the groove 104 is a trapezoidal groove structure, so as to guide the third limiting part 122 to engage with the fourth limiting part 103 more quickly, thereby further improving the efficiency of disassembly and assembly of the machine body.

[0048] It is understandable that the bottom of the housing 100 is provided with a connection hole, which is used to engage and connect with the mission payload required to be mounted on the body structure.

[0049] For example, in this embodiment, the bottom of the housing 100 is provided with connection holes at the four corners, and the side of the task load near the housing 100 is provided with a connection post that is adapted to the connection hole. The connection hole and the connection post are engaged to ensure that the task load can be stably placed at the bottom of the housing 100. At the same time, the housing 100 carrying the task load also improves the application scenarios and scope of the body structure of this application.

[0050] It is understandable that the battery 110 has a start switch 105 on the side near the side cover 120, and the side cover 120 also has a through hole 123 corresponding to the start switch 105.

[0051] For example, in some embodiments, reference is made to Figure 1 and Figure 2 In this embodiment, the battery 110 is provided with a start switch 105, and the side cover 120 is provided with a through hole 123 corresponding to the start switch 105. The through hole 123 connects the chamber 101 and the outside of the housing 100. The operator can press the start switch 105 through the through hole 123 to start or stop the battery 110 without having to remove the side cover 120 to press the start switch 105, which improves the flexibility of the machine.

[0052] The drone according to the second aspect of the application includes the airframe structure of the first aspect of the application described above.

[0053] According to the drone of this application embodiment, the application provides a housing 100 to house the battery 110, thereby protecting the battery 110 and preventing accidental damage to the exposed battery 110 due to collisions during drone use, thus reducing maintenance costs. The battery assembly facilitates the provision of power to various modules connected to the drone body. The first limiting part 102 on the housing 100 and the second limiting part 111 on the battery 110 facilitate the rotation of the second limiting part 111 towards the first limiting part 102 when the battery 110 is fully placed in the chamber 101, causing the second limiting part 111 to engage with the first limiting part 102. To prevent the battery 110 from detaching from the chamber 101, thereby reducing the risk of damage to the battery 110 due to detachment from the chamber 101 and reducing production costs, when it is necessary to remove the battery 110, the second limiting part 111 can be rotated away from the first limiting part 102, so that the second limiting part 111 and the first limiting part 102 are disengaged, allowing the battery 110 to be smoothly detached from the chamber 101. This simplifies the process of installing and removing the battery 110 and improves the efficiency of assembling or disassembling the body. By introducing the body structure of this application, the efficiency of assembling and disassembling the UAV of this application is improved, thereby reducing the time cost required for production.

[0054] Since the UAV includes the airframe structure of the first aspect embodiment, the corresponding contents of the airframe structure in the first aspect embodiment can be applied to the UAV of the second aspect, and have the same implementation principle and technical effect. To avoid redundancy, it will not be described in detail here.

[0055] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
