[0002] With the development of drone technology, drones are being used more and more widely in fields such as agriculture, surveying, logistics, security, power, environmental protection, film and television, scientific research, and education. Conventional drone canopies and fuselages are usually connected by screws. However, in some applications, drones require frequent disassembly and reassembly of the canopy and fuselage, and there is a need to minimize replacement time. The existing screw connection method requires tools, and the disassembly process can easily cause parts to fall off, resulting in relatively low efficiency. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention provides a canopy connection structure and a drone to improve the technical problems of long disassembly and assembly time and relatively low disassembly and assembly efficiency of the existing drone canopy and shell.

[0004] To achieve the above and other related objectives, the first aspect of this utility model provides a hatch connection structure, which includes a hatch, a housing, and a locking mechanism. The housing includes an opening, and the hatch covers the opening. The locking mechanism includes a connecting rod, an elastic element, and a stop block. The connecting rod passes through the hatch and is rotatably slidably connected to the hatch. The elastic element is located on one side of the hatch and abuts against the hatch and the connecting rod. The stop block is located on the other side of the hatch and is fixedly connected to the connecting rod. The stop block has a first position abutting against the housing and a second position avoiding the housing. In the first position, the stop block and the hatch are pressed against both sides of the housing.

[0005] In one embodiment of the hatch connection structure of this utility model, the locking mechanism further includes a seat body, the seat body is installed on the hatch cover, the connecting rod passes through the seat body and is fixedly connected to the stop block, and the elastic member abuts against the hatch cover through the seat body.

[0006] In one embodiment of the hatch connection structure of this utility model, a limiting structure is further provided between the seat and the stop block. The limiting structure includes a first protrusion and a groove. The first protrusion is disposed on one of the seat and the stop block, and the groove is correspondingly disposed on the other of the seat and the stop block. In the first position, the first protrusion is inserted into the groove.

[0007] In one embodiment of the hatch connection structure of this utility model, the connecting rod is detachably and fixedly connected to the stop block; the seat is detachably and fixedly connected to the hatch.

[0008] In one embodiment of the hatch connection structure of this utility model, the elastic element is a compression spring, which is sleeved on the outside of the connecting rod.

[0009] In one embodiment of the hatch connection structure of this utility model, the locking mechanism further includes a handle portion, which is disposed at the end of the connecting rod away from the stop block.

[0010] In one embodiment of the hatch connection structure of this utility model, the length direction of the handle portion is consistent with the length direction of the stop block when projected along the axial direction of the connecting rod.

[0011] In one embodiment of the hatch connection structure of this utility model, a stepped portion is provided on the housing located at the opening, and the hatch is embedded into the stepped portion.

[0012] In one embodiment of the hatch connection structure of this utility model, the locking mechanism is located at the edge of the hatch, and the number of locking mechanisms is multiple.

[0013] A second aspect of this utility model also provides an unmanned aerial vehicle (UAV) comprising the canopy connection structure described in any of the preceding claims.

[0014] This utility model provides a canopy connection structure and a drone. In this canopy connection structure, a locking mechanism is provided on the canopy for connection with the fuselage. Compared to the method of installing the locking mechanism directly on the fuselage, this reduces the installation difficulty of the locking mechanism, simplifies the installation process, and reduces damage to the structural strength of the fuselage. The cooperative rotation design of the connecting rod and the stop block allows for quick installation and removal of the canopy from the fuselage without the need for other tools, reducing installation and removal time and improving efficiency.

[0029] To address the technical issues of long assembly and disassembly times and relatively low efficiency in existing drone canopy and fuselage installations, this invention provides a canopy connection structure and a drone. This canopy connection structure allows for quick installation and removal of the canopy from the fuselage without the need for additional tools, reducing assembly and disassembly time and improving efficiency.

[0030] Please see Figures 1 to 8 The first aspect of this utility model provides a hatch connection structure, which includes a hatch 100, a housing 200, and a locking mechanism 300. The housing 200 includes an opening 210, the shape of which is adapted to the hatch 100, and the hatch 100 covers the opening 210. The locking mechanism 300 serves as a connecting and locking element between the hatch 100 and the housing 200, enabling quick assembly and disassembly of the hatch 100 and the housing 200.

[0031] Please see Figure 5 and Figure 6 The locking mechanism 300 includes a connecting rod 310, an elastic element 320, and a stop block 330. The connecting rod 310 passes through the hatch 100 and is rotatably slidably connected to it. Specifically, one end of the connecting rod 310 is located outside the housing 200, and the other end is located inside the housing 200. The sliding direction of the connecting rod 310 is consistent with the installation direction of the hatch 100. The connecting rod 310 located outside the housing 200 is the operating end, used by the operator to manually control the sliding or rotation of the connecting rod 310. The connecting rod 310 located inside the housing 200 is the mounting end of the stop block 330; rotating the connecting rod 310 controls the rotation of the stop block 330.

[0032] The elastic element 320 is located on one side of the hatch cover 100, with its two ends abutting against the hatch cover 100 and the connecting rod 310, respectively. Specifically, the elastic element 320 is located on the outer side of the hatch cover 100. One end of the elastic element 320 can directly abut against the hatch cover 100, or it can indirectly abut against the hatch cover 100 through intermediate parts such as mounting seats, as long as it can provide a pushing force to the hatch cover 100 in the sliding direction of the connecting rod 310. The other end of the elastic element 320 abuts against the connecting rod 310. The connecting rod 310 has a boss or stop for the elastic element 320 to abut against, or it can directly abut against the handle portion on the connecting rod 310, as long as it can provide a pushing force to the connecting rod 310 in the sliding direction of the connecting rod 310. The elastic element 320 provides a preload along the axial direction of the connecting rod 310, ensuring that the hatch 100 remains firmly pressed against the housing 200 when locked onto the housing 200. The type of elastic element 320 is not limited, and it can be, for example, a compression spring, an elastic airbag, an elastic rubber block, etc., but is not limited thereto.

[0033] Please see Figures 3 to 6 The stop block 330 is located on the other side of the hatch 100 and is fixedly connected to the connecting rod 310. Specifically, the stop block 330 is located inside the housing 200. The stop block 330 cooperates with the hatch 100 to press the housing 200 located at the opening 210. The fixed connection method between the stop block 330 and the connecting rod 310 is not limited; it can be welding, bonding, or screw connection, as long as it can ensure a stable connection between the stop block 330 and the connecting rod 310. Among them, the stop block 330 has a first position abutting against the housing 200. When the stop block 330 is in the first position, its axial projection along the connecting rod 310 at least partially overlaps with the housing 200. In the first position, the stop block 330 and the hatch 100 are pressed against both sides of the housing 200, thereby pressing and fixing the hatch 100 and the housing 200. The stop block 330 has a second position that avoids the housing 200. When the stop block 330 is in the second position, its axial projection along the connecting rod 310 shows no overlap between the stop block 330 and the housing 200. The locking mechanism 300 releases the locking between the hatch 100 and the housing 200, thereby achieving the separation of the hatch 100 and the housing 200.

[0034] In this hatch connection structure, the locking mechanism 300 is installed on the hatch 100. Compared to the installation method where the locking mechanism 300 is installed on the housing 200, the reasonable use of the hatch 100's disassembly and assembly design reduces the installation difficulty of the locking mechanism 300, simplifies the installation process, and reduces damage to the structural strength of the housing 200. The cooperative rotation design between the connecting rod 310 and the stop block 330, and the sliding connection of the connecting rod 310 on the hatch 100, allow for quick installation and removal of the hatch 100 from the housing 200 without the need for other tools, reducing the installation and removal time of the hatch 100 and improving its efficiency. Pressing and rotating the connecting rod 310 rotates the stop block 330 to the first position, limiting the displacement of the hatch cover 100 in the installation direction. Simultaneously, the elastic element 320 provides a certain preload, ensuring a seamless fit between the hatch cover 100 and the housing 200 in the installation direction. This prevents air leakage or vibration caused by gaps, ensuring the stability of the connection between the hatch cover 100 and the housing 200. Pressing and rotating the connecting rod 310 in the opposite direction rotates the stop block 330 to the second position, whereby the stop block 330 no longer interferes with the housing 200, allowing for quick disassembly of the hatch cover 100. The locking mechanism 300 locks or unlocks the hatch cover 100 with simple pressing and rotation, simplifying operation and meeting the requirements for frequent disassembly and assembly of the hatch cover 100.

[0035] Please see Figure 5 and Figure 6 In one embodiment of the hatch connection structure of this utility model, the locking mechanism 300 further includes a seat 340, which is mounted on the hatch 100. A connecting rod 310 passes through the seat 340 and is fixedly connected to a stop block 330. An elastic member 320 abuts against the hatch 100 through the seat 340. Specifically, in this embodiment, the connecting rod 310 is rotatably slidably connected to the hatch 100 through the seat 340. The seat 340 serves as the mounting base for the locking mechanism 300. The seat 340 has a first through hole 341 and a second through hole 342 that are coaxially connected. The radial dimension of the first through hole 341 is larger than the radial dimension of the second through hole 342. The connecting rod 310 passes through the first through hole 341 and the second through hole 342 in sequence. A truncated ring is formed at the junction of the first through hole 341 and the second through hole 342. The truncated ring is used to abut one end of the elastic member 320. The design of the base 340 reduces the structural design of the original hatch 100. It only requires opening mounting holes on different types of hatches 100 to adapt to the base 340, thereby improving the versatility of the locking mechanism 300.

[0036] Please see Figure 5 and Figure 6In one embodiment of the hatch connection structure of this utility model, a limiting structure 400 is further provided between the seat 340 and the stop block 330. The limiting structure 400 restricts the rotation of the stop block 330 in the locked state, preventing the stop block 330 from disengaging from the first position due to external force, and avoiding the locking mechanism 300 from failing to lock. The limiting structure 400 includes a first protrusion 410 and a groove 420. The first protrusion 410 is disposed on one of the seat 340 and the stop block 330, and the groove 420 is correspondingly disposed on the other of the seat 340 and the stop block 330. In the first position, the first protrusion 410 is inserted into the groove 420. In this embodiment, the first protrusion 410 is disposed on the seat 340 and located at the end of the seat 340 facing the stop block 330, and the groove 420 is correspondingly formed on the stop block 330. The limiting structure 400 also includes a second protrusion 430, which is disposed on the seat 340 and located at the end of the seat 340 facing the stop block 330. When the stop block 330 is in the second position, the second protrusion 430 is inserted into the groove 420. Specifically, when the hatch 100 needs to be locked, the operator presses the connecting rod 310 until the groove 420 disengages from the second protrusion 430, and then rotates the connecting rod 310 to rotate the stop block 330 to the first position. The elastic element 320 is in a compressed state. When the operator releases the pressure, the elastic element 320 drives the connecting rod 310 to return to its original position, and the first protrusion 410 is inserted into the groove 420. The elastic element 320 cooperates with the hatch 100 and presses it against both sides of the housing 200, thereby locking and limiting the hatch 100 along the installation direction and preventing the hatch 100 from rotating around the installation direction. Ensure the stability of the locking mechanism 300. Conversely, release the locking of the hatch 100 if the locking mechanism fails to lock. This will not be elaborated further here.

[0037] Please see Figure 5 In one embodiment of the hatch connection structure of this utility model, the connecting rod 310 and the stop block 330 are detachably fixedly connected. Specifically, in this embodiment, the connecting rod 310 and the stop block 330 are locked and fixed by a fastener 500, which includes a screw 510 and a washer 520. The end of the connecting rod 310 is provided with a threaded hole 311, which is adapted to the screw 510. The screw 510 and the washer 520 cooperate to lock and fix the stop block 330 to the end of the connecting rod 310. Furthermore, the connecting rod 310 is a round rod, and the connecting rod 310 and the stop block 330 are inserted through a tenon and mortise structure 600 and locked and fixed by the fastener 500. Specifically, a tenon 610 is provided at the end of the round rod, and a mortise 620 is provided on the stop block 330 corresponding to the tenon 610. The tenon 610 is inserted into the mortise 620, which can restrict the rotation of the stop block 330 relative to the connecting rod 310, and at the same time reduce the assembly difficulty of the fastener 500 to the stop block 330.

[0038] Please see Figure 6 The seat 340 is detachably and fixedly connected to the hatch 100. Specifically, in this embodiment, the seat 340 and the hatch 100 are connected by bolts or screws, and the hatch 100 has mounting holes adapted to the seat 340. The detachable structural design of the seat 340 makes the locking mechanism 300 a universal connector. It only requires mounting holes adapted to the seat 340 to be made on different types of hatches 100, without the need for a complex structural design of the hatch 100 to match the installation of the locking mechanism 300.

[0039] Please see Figure 5 In one embodiment of the hatch connection structure of this utility model, regardless of whether the locking mechanism 300 is in the locked or unlocked state, the elastic element 320 provides a set of reverse pushing forces to the connecting rod 310 and the hatch 100. Specifically, in this embodiment, the elastic element 320 is a compression spring, which is always in a compressed state. In the locked state, the pushing force provided by the elastic element 320 ensures that the stop block 330 can be firmly pressed against the housing 200, reducing the risk of the hatch 100 being accidentally unlocked due to external forces. The compression spring is sleeved on the outside of the connecting rod 310, and the connecting rod 310 provides good compression or rebound guidance for the compression spring, while also reducing the installation difficulty of the compression spring.

[0040] Please see Figure 1 and Figure 5 In one embodiment of the hatch connection structure of this utility model, the locking mechanism 300 further includes a handle portion 350. The handle portion 350 is disposed at one end of the connecting rod 310 away from the stop block 330. The handle portion 350 and the connecting rod 310 can be an integral structure or a separate detachable connection structure. Specifically, in this embodiment, the handle portion 350 and the connecting rod 310 are an integral structure. The shape of the handle portion 350 is not limited; it can be plate-shaped, rod-shaped, column-shaped, or other irregularly shaped structures that can improve operational convenience, providing the operator with a larger gripping area and facilitating pressing and rotating of the connecting rod 310.

[0041] Please see Figure 1 and Figure 5 In one embodiment of the hatch connection structure of this utility model, along the axial projection of the connecting rod 310, the length direction of the handle portion 350 is consistent with the length direction of the stop block 330. Specifically, in this embodiment, the handle portion 350 is the gripping end for the operator to press or rotate the connecting rod 310. The handle portion 350 is a rectangular plate and is fixed to the end of the connecting rod 310. The stop block 330 is a strip-shaped locking tongue structure. The length direction of the handle portion 350 is consistent with the length direction of the stop block 330. The position of the stop block 330 can be determined by observing the position of the handle portion 350 relative to the housing 200, thus more accurately determining the state of the locking mechanism 300 and further reducing operator oversight. It should be noted that... (Please refer to...) Figure 5 The length direction of the handle portion 350 and the length direction of the stop block 330 both refer to the X-axis.

[0042] Please see Figure 2 and Figure 5 In one embodiment of the canopy connection structure of this utility model, a step portion 220 is provided on the housing 200 located at the opening 210. The step portion 220 surrounds the opening 210 and is adapted to the canopy 100, with the canopy 100 embedded in the step portion 220. The step portion 220 reduces the positioning difficulty of the canopy 100, making the assembly process of the canopy 100 more intuitive and convenient, and improving assembly efficiency. At the same time, the outer surface of the canopy 100 is flush with the surface of the housing 200 outside the step portion 220. The flush surface design reduces the airflow resistance between the canopy 100 and the housing 200, optimizing the aerodynamic performance of the UAV. It also reduces the vibration of the canopy 100 caused by airflow impact, further ensuring the locking and fixing effect of the locking mechanism 300.

[0043] In one embodiment of the hatch connection structure of this utility model, the locking mechanism 300 is located at the edge of the hatch 100. The number of locking mechanisms 300 can be one set or multiple sets, as long as a stable connection between the hatch 100 and the housing 200 can be achieved. For details, please refer to [link to relevant documentation]. Figures 1 to 3 In this embodiment, there are two sets of locking mechanisms 300. The two sets of locking mechanisms 300 are arranged opposite to each other on the two sides of the hatch 100, which facilitates the hatch 100 to be locked and fixed to the housing 200 by the stop block 330.

[0044] The second aspect of this utility model also provides an unmanned aerial vehicle (UAV) including the canopy connection structure described in any of the above embodiments. It should be noted that the UAV of this utility model may also include conventional structures and system modules of existing UAVs such as a power system, control system, fuselage, communication system, rotor system, avionics system, and landing gear, but is not limited thereto, and will not be described in detail here.

[0045] In the canopy connection structure and UAV of this utility model, a locking mechanism for connecting the canopy to the fuselage is provided. Compared with the installation method of the locking mechanism on the fuselage, the installation difficulty of the locking mechanism can be reduced, the installation process can be simplified, and the damage to the structural strength of the fuselage can be reduced. The cooperative rotation design of the connecting rod and the stop block can quickly install and remove the canopy from the fuselage without the need for other tools, reducing the installation and removal time and improving the efficiency. At the same time, the elastic element provides a certain preload, so that the canopy and the fuselage fit together seamlessly in the installation direction, avoiding air leakage or vibration caused by gaps, ensuring the connection stability between the canopy and the fuselage, and improving the flight stability of the UAV. This improves the technical problems of long installation and removal time and relatively low efficiency of existing UAV canopy and fuselage connections. Therefore, this utility model effectively overcomes some practical problems in the prior art and has high utilization value and significance.

[0046] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
