Description

TECHNICAL FIELD

[0002] An unmanned aerial vehicle, referred to as a "drone", is a flying device controlled by radio remote control equipment and autonomous program control system. Due to its strong maneuverability, quick response, no need for manual driving, easy operation and the advantage of carrying various small devices or goods, the unmanned aerial vehicle has been widely used in many fields such as agriculture, logistics, environmental monitoring and military reconnaissance. In these applications, the gimbal, as one of the core components of the unmanned aerial vehicle, undertakes the heavy task of image acquisition and stable control.

[0003] At present, the unmanned aerial vehicles on the market usually need to carry multiple different types of gimbals or other mounting devices, and often need to frequently disassemble and replace the gimbals. However, the gimbals of most unmanned aerial vehicles are connected to the unmanned aerial vehicle body through screws. This connection method not only needs to use disassembly tools, but also has the risk of bumping the gimbal lens during disassembly, which may cause damage or scratches to the lens, thereby affecting the shooting function. More inconveniently, the operator often cannot carry the required tools during the disassembly process, increasing the complexity of the operation and reducing the work efficiency.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. It should be noted that, unless otherwise specified, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0037] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] One aspect of this application provides a gimbal connection device, aiming to provide a more convenient and secure connection method between the gimbal and the drone body, solving the problem that the gimbal disassembly process in the prior art is cumbersome and easily damages the gimbal lens. The gimbal connection device includes two main parts: a first connector 10 and a second connector 20. The first connector 10 is used to connect to the drone body, while the second connector 20 is used to connect to the gimbal.

[0039] Specifically, such as Figures 1 to 4As shown, the inner wall of the first connecting seat 10 has a locking groove 11, and the locking protrusion 211 is located on the outer periphery of the second connecting seat 20. The locking protrusion 211 is rotatably connected to the locking groove 11. In addition, the gimbal connection device also includes a limiting member 12 and a limiting post 221. The limiting member 12 is movably mounted on the first connecting seat 10, and the limiting post 221 is mounted on the second connecting seat 20. The engagement of the limiting member 12 and the limiting post 221 restricts the rotation of the locking protrusion 211 relative to the locking groove 11. When the locking protrusion 211 rotates through the locking groove 11 until the limiting member 12 engages with the limiting post 221, the locking protrusion 211 stops rotating and engages between the two side walls of the locking groove 11 along the rotation axis of the second connecting seat 20, thereby effectively restricting the rotation of the second connecting seat 20 relative to the first connecting seat 10 or its movement along the rotation axis. At this time, the second connecting seat 20 and the first connecting seat 10 are fixedly connected and no longer have relative displacement. The connection between the gimbal and the drone body can be firmly guaranteed, ensuring the stability of the gimbal during use. At the same time, the cooperation of the limiting component 12 and the limiting post 221 can also prevent the gimbal from loosening or vibrating unnecessarily.

[0040] When the gimbal needs to be replaced or repaired, the limiting member 12 can be moved away from the limiting post 221 to disengage the limiting member 12 from the limiting post 221. At this time, the fixed connection between the second connecting seat 20 and the first connecting seat 10 is released. The operator only needs to rotate the second connecting seat 20 to disengage the locking protrusion 211 from the side wall of the locking groove 11, thus completing the quick disassembly of the gimbal from the drone body.

[0041] In summary, the gimbal connection device provided in this application enables the installation and removal of the gimbal without the need for additional tools, greatly improving the simplicity and flexibility of operation and effectively avoiding the risk of gimbal lens damage. Simultaneously, the disassembly process is simple, labor-saving, and quick, significantly improving the efficiency of gimbal replacement and maintenance. Furthermore, operators do not need to carry disassembly and assembly tools, reducing cumbersome steps and improving work efficiency, making it particularly suitable for applications requiring frequent gimbal replacement or maintenance.

[0042] Optionally, a first notch is provided on the side wall of the snap-fit ​​groove, and the first notch communicates with the groove opening of the snap-fit ​​groove. The size of the first notch 111 is greater than or equal to the size of the snap-fit ​​protrusion 211. With this design, the snap-fit ​​protrusion 211 can slide into the snap-fit ​​groove 11 through the first notch 111 and achieve a rotatable connection with the snap-fit ​​groove 11. When the gimbal needs to be replaced or repaired, the limiting member 12 can be moved away from the limiting post 221 by driving the limiting member 12 to disengage from the limiting post 221. At this time, the fixed connection between the second connecting seat 20 and the first connecting seat 10 is released. The operator only needs to rotate the second connecting seat 20, so that the snap-fit ​​protrusion 211 rotates along the snap-fit ​​groove 11 until the snap-fit ​​protrusion 211 aligns with the first notch 111, and then slides out of the snap-fit ​​groove 11 through the first notch 111, completing the quick disassembly of the gimbal and the drone body.

[0043] Optionally, such as Figure 2 and Figure 3 As shown, a through mounting groove is provided on the side wall of the first connecting seat 10, which is used for the installation and movement of the limiting member 12. The limiting member 12 is installed in the mounting groove of the first connecting seat 10 by means of a fixing member that moves radially along the rotation of the second connecting seat 20. This installation method ensures that the limiting member 12 can move freely in the radial direction, thereby playing a flexible adjustment role during disassembly or installation. At the same time, it can prevent the limiting member 12 from failing to effectively engage with the limiting post 221 or from moving excessively and completely disengaging from the first connecting seat 10 when moving in other directions. One end of the limiting member 12 is located outside the first connecting seat 10, which is convenient for the operator to drive directly, so as to achieve ease of operation. The operator only needs to easily drive the outer end of the limiting member 12 to make it move radially, thereby initiating the engagement with or disengaging from the limiting post 221.

[0044] The other end of the limiting member 12 is equipped with a limiting hook, which is located inside the first connecting seat 10 and cooperates with the limiting post 221 provided on the second connecting seat 20. This hook ensures the connection or disassembly of the gimbal and the drone body by engaging or disengaging the gimbal. When the limiting member 12 is driven to move radially along the rotation of the second connecting seat 20, it can precisely engage or disengage with the limiting post 221. When the limiting member 12 engages with the limiting post 221, the tight cooperation between the limiting hook and the limiting post 221 effectively restricts the relative rotation between the gimbal and the first connecting seat 10, ensuring the stability of the connection. After disengaging, the connection between the gimbal and the first connecting seat 10 is released, allowing the operator to easily disassemble the gimbal.

[0045] Optionally, such as Figure 5As shown, the gimbal connection device also includes an elastic element 16, one end of which abuts against the limiting element 12, and the other end abuts against the first connecting seat 10. When an external driving force is applied to the limiting element 12, the limiting element 12 moves away from the limiting post 221, while simultaneously compressing the elastic element 16 to store a certain amount of energy. As the external force is removed, the elastic element 16 releases the stored energy, generating a restoring force that pushes the limiting element 12 towards the limiting post 221, causing the limiting element 12 to automatically return to its original position. This design not only allows the limiting element 12 to disengage from the limiting post 221 under the action of external force during disassembly, but also ensures that the limiting element 12 can automatically reset after the external force is removed, without any additional operation.

[0046] When the gimbal needs to be disassembled, the operator only needs to apply external force to drive the limiting member 12, causing it to disengage from the limiting post 221. As the external force is removed, the restoring force of the elastic member 16 will automatically reset the limiting member 12 and maintain its original state, ensuring the structural stability of the gimbal connection device after disassembly. This process avoids complex operations during disassembly and effectively reduces the burden on the operator.

[0047] Furthermore, the design of the elastic element 16 eliminates the need for additional operation of the limiting element 12 to reset during gimbal installation. Because the elastic element 16 automatically resets the limiting element 12, it quickly returns to its aligned position with the limiting post 221 during installation, ensuring ease of installation. The entire installation process requires no tools or additional operation; the operator simply rotates the limiting post 221 to align with the limiting element 12, which automatically engages and resets, improving the connection efficiency and stability between the gimbal and the drone.

[0048] Optionally, such as Figure 6 and Figure 7 As shown, the second connecting seat 20 consists of a rotating base 21 and a rotating plate 22 fixedly installed on the rotating base 21 near the first connecting seat 10. The design of the rotating base 21 enables more efficient connection and disassembly operations for the entire connecting device. The outer periphery of the rotating base 21 is provided with a snap-fit ​​protrusion 211 that is rotatably connected to the snap-fit ​​groove 11. The snap-fit ​​protrusion 211 tightly engages with the snap-fit ​​groove 11 within the first connecting seat 10, enabling a rotatable connection between the gimbal and the drone body. This rotatable connection design allows the rotating base 21 to drive the snap-fit ​​protrusion 211 to rotate along the snap-fit ​​groove 11 during disassembly or installation, facilitating the connection and disassembly between the gimbal and the drone body.

[0049] The rotating plate 22 is designed to cooperate with the limiting member 12, and a limiting post 221 that cooperates with the limiting member 12 is provided on the rotating plate 22. Through cooperation with the limiting member 12, the limiting post 221 effectively limits the rotation range of the locking protrusion 211, ensuring a stable and safe connection between the gimbal and the drone body. When the locking protrusion 211 rotates along the locking groove 11 to the set position, the limiting post 221 engages with the limiting member 12, thereby preventing the locking protrusion 211 from continuing to rotate. This limiting effect effectively prevents connection instability or damage that may result from excessive rotation.

[0050] Optionally, such as Figure 6 and Figure 7 As shown, the rotating plate 22 is detachably inserted into the rotating base 21, a design that allows the rotating base 21 and the rotating plate 22 to operate independently. The inner wall of the first connecting seat 10 is provided with a first protrusion 13 extending radially along the rotation of the second connecting seat 20. Simultaneously, the outer periphery of the rotating plate 22 is also provided with a second protrusion 222 extending radially along the rotation of the second connecting seat 20. The first protrusion 13 and the second protrusion 222 extend in opposite directions. This design ensures that the two protrusions can cooperate with each other during rotation and engage along the rotational axis of the second connecting seat 20. Through this cooperation, the first protrusion 13 and the second protrusion 222 always restrict the movement of the rotating plate 22 in the rotational axis, thereby ensuring that the rotating plate 22 can be firmly held on the first connecting seat 10.

[0051] In actual operation, when the rotating base 21 drives the snap-fit ​​protrusion 211 to rotate along the snap-fit ​​groove 11 to the position aligned with the first notch 111, the rotating base 21 can be detached from the first connecting seat 10, while the rotating plate 22 remains in place. This design simplifies the disassembly process, eliminating the need to disassemble the rotating plate 22, making the disassembly and replacement of the gimbal more efficient. When the rotating base 21 needs to be reinstalled, the operator simply inserts the rotating base 21 into the rotating plate 22, then rotates the rotating base 21, causing the rotating plate 22 to rotate together. During the rotation, the limiting post 221 snaps into the limiting member 12, ensuring a secure connection. Simultaneously, the snap-fit ​​protrusion 211 also snaps into the snap-fit ​​groove 11, thereby achieving a fixed connection between the second connecting seat 20 and the first connecting seat 10. This design allows the rotating base 21 and the rotating plate 22 to easily align without additional adjustments, ensuring a quick and precise connection between the second connecting seat 20 and the first connecting seat 10.

[0052] Optionally, such as Figures 3 to 7As shown, an abutment groove 14 is formed on the inner wall of the first connecting seat 10, and the groove has a first sidewall 141 and a second sidewall 142 arranged opposite to each other. A third protrusion 223 is provided on the outer periphery of the rotating plate 22, extending radially along the second connecting seat 20. The engaging protrusion 211 on the rotating base 21 drives the third protrusion 223 to rotate, causing it to alternately abut against the first sidewall 141 and the second sidewall 142 of the abutment groove 14. When the gimbal needs to be installed, the rotating base 21 is driven to rotate, causing the limiting post 221 to rotate to a predetermined position where it engages with the limiting member 12. At this time, the third protrusion 223 engages with the first sidewall 141, forming a double limiting effect, preventing the rotating base 21 and the rotating plate 22 from continuing to rotate, thereby ensuring a fixed connection between the second connecting seat 20 and the first connecting seat 10. This design ensures that the gimbal will not loosen or shift after installation, ensuring the stability and safety of the connection.

[0053] During disassembly, the rotating base 21 is driven to rotate in the opposite direction, causing the locking protrusion 211 to rotate until it aligns with the first notch 111. Simultaneously, the third protrusion 223 abuts against the second sidewall 142. At this point, the rotating base 21 and the rotating plate 22 can no longer rotate, thus ensuring that the rotating base 21 can be smoothly disassembled, and that the rotating plate 22 remains in its original position without excessive rotation or misalignment. This design provides clear operational positioning during disassembly, avoiding damage to components or misalignment of connecting parts due to improper operation, and ensuring accurate alignment of the rotating base 21 and the rotating plate 22 during subsequent installation.

[0054] Optionally, such as Figure 8 As shown, a first identifier 15 is provided on the first connector 10 to provide operators with a positional reference during installation and disassembly. A second identifier 23 and a third identifier 24 are respectively provided on the second connector 20. The second identifier 23 serves as a locking identifier, indicating the locked position of the component during connection, while the third identifier 24 serves as an unlocking identifier, indicating the unlocked position of the component during disassembly. This identifier system design allows operators to quickly and accurately identify the current connection status during connection or disassembly operations, thereby ensuring a smooth and stable connection process.

[0055] When the third protrusion 223 rotates to abut against the first sidewall 141, the first mark 15 and the second mark 23 will be arranged along the rotation axis of the second connecting seat 20. At this time, the operator can visually confirm the position of each connecting component through these marks and ensure that they are in the locked state, thereby achieving a stable connection between the gimbal and the drone body. When the third protrusion 223 rotates to abut against the second sidewall 142, the first mark 15 and the third mark 24 will be arranged along the rotation axis of the second connecting seat 20. This mark layout can clearly indicate the correct position for unlocking operations, helping the operator to smoothly disassemble or adjust the connecting components.

[0056] Optionally, such as Figures 3 to 7 As shown, a limiting groove 224 is formed on the side of the rotating plate 22 away from the rotating base 21, and a limiting post 221 is fixedly set in the bottom wall of the limiting groove 224. The height of the limiting post 221 along the rotation axis of the second connecting seat 20 is designed to be less than or equal to the depth of the limiting groove 224 along the rotation axis. The main advantage of this setting is that the limiting post 221 will not protrude from the surface of the rotating plate 22, thus effectively avoiding occupying unnecessary space. Since the limiting post 221 is completely located within the limiting groove 224, the overall design of the device is more compact, ensuring the simplicity and efficiency of the gimbal connection device. This design not only improves the stability of the overall structure, but also ensures that the device can operate stably in a smaller space during operation, avoiding interference and potential risks caused by excessive space or exposed parts.

[0057] A second notch is provided on the side wall of the limiting groove 224 near the limiting member 12, and this notch communicates with the groove opening of the limiting groove 224. The design of the second notch provides a convenient channel for the limiting member 12 to move radially along the rotation of the second connecting seat 20, so that the limiting member 12 can pass through the mounting groove of the first connecting seat 10 and the second notch in sequence, and engage or disengage with the limiting post 221.

[0058] Optionally, such as Figure 8 and Figure 9 As shown, a protective cover 30 is provided on the side of the first connector 10 near the drone body, and a sealing ring is used to achieve a sealed connection with the first connector 10. As a key component, the sealing ring ensures that there are no gaps between the protective cover 30 and the first connector 10, thereby preventing dust, moisture, and other substances from the external environment from entering the connecting parts and avoiding unstable connections or component damage due to external interference. The use of the sealing ring makes the connection between the protective cover 30 and the first connector 10 tighter and more stable, enhancing the protection of the device, and is particularly suitable for drones used in complex outdoor environments.

[0059] Optionally, the first connecting seat 10 and the second connecting seat 20 are sealed together to achieve strict isolation between the interior and exterior environments of the connecting seats. The sealed connection can be achieved by using sealing rings, rubber gaskets, or other elastic sealing materials to ensure a complete seal at the joint between the two connecting seats. The sealed connection between the first connecting seat 10 and the second connecting seat 20 further prevents dust, water droplets, or other external factors from intruding into the connecting components, avoiding corrosion, wear, or performance degradation of mechanical parts due to contamination or a humid environment.

[0060] Optionally, such as Figure 9 As shown, a wire-threading plug 40 is provided on the side wall of the first connector 10 to prevent the entry of external dust, moisture, or other contaminants during cable connection, thereby protecting the connecting wire from damage. The wire-threading plug 40, through its elastic properties, fits tightly with the first connector 10 to form a sealed connection, effectively preventing the influence of the external environment on the connection system, especially providing strong protection in high humidity or dusty environments.

[0061] In another aspect of this application, a drone is provided, including a drone body, a gimbal, and a gimbal connection device of any one of the above-described types. The gimbal is detachably connected to the drone body via the gimbal connection device. Since the drone uses the aforementioned gimbal connection device, it also has the same beneficial effects as the gimbal connection device, which will not be described in detail here.

[0062] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
