Description

Technical Field

[0001] This utility model relates to the field of drone technology, and in particular to a drone protective cover and drone with a tool-free quick-assembly and disassembly structure. Background Technology

[0002] Existing drone protective shrapnel typically consists of multiple independent parts, primarily designed to protect the drone's propellers and prevent them from being damaged by obstacles during flight, thus avoiding a crash.

[0003] Currently, drone protective clips typically employ an arc-shaped design, with the arc length corresponding to the outer contour of the propeller blades. These arc-shaped clips are installed under the propeller blades via a snap-fit ​​mechanism, making installation and removal simple and meeting the basic protection requirements of drones. However, the snap-fit ​​installation method also suffers from low structural strength. Under special operating conditions such as high-speed flight, the protective clips can still detach upon impact, damaging the propeller blades and affecting drone flight safety. Utility Model Content

[0004] This invention provides a tool-free, quick-assembly and disassembly structure for a drone protective cover and a drone, which solves the problem of low strength and relatively poor protection of propellers in existing drone spring clip structures.

[0005] One embodiment of this utility model provides a tool-free, quick-assembly and disassembly structure for a drone protective cover, including a bracket assembly. The bracket assembly includes an anti-collision component corresponding to the position of the drone propeller, and a locking component fixedly connected to the anti-collision component. The locking component is used to fix the drone propeller fixing arm.

[0006] Furthermore, the locking component includes an annular fixing hole, which is used to fit onto the propeller fixing arm of the UAV.

[0007] Furthermore, the locking component includes an upper pipe clamp and a lower pipe clamp, which are connected by a first pivot so that the upper and lower pipe clamps can be closed or opened relative to each other. The upper and lower pipe clamps have notches formed at their respective positions. When the upper and lower pipe clamps are closed relative to each other, the upper and lower pipe clamps form the annular fixing hole at the position of the notch.

[0008] Furthermore, the lower pipe clamp is provided with a first clearance groove, and the upper pipe clamp is provided with a second clearance groove. The first clearance groove and the second clearance groove are connected and located on the side of the locking member. The locking member also includes a latch provided in the first clearance groove and the second clearance groove. The latch is used to fix the upper pipe clamp and the lower pipe clamp so that the upper pipe clamp and the lower pipe clamp are kept in a closed state.

[0009] Furthermore, the lower tube clamp forms a second pivot at the first clearance groove, the upper tube clamp forms a clearance groove at the top of the second clearance groove, the bottom of the clearance groove forms a top stop surface, the latch includes a stud and a nut, one end of the stud is disposed on the second pivot and can rotate along the second pivot, the other end of the stud is fitted with the nut, when the stud rotates into the second clearance groove, the nut slides into the clearance groove, and the nut is detachably stopped on the top stop surface.

[0010] Furthermore, the number of anti-collision components corresponds to the number of drone propellers. Each anti-collision component includes two end supports arranged opposite each other, and also includes a strut connected between the two end supports arranged opposite each other. The anti-collision component also includes a first stop bar connected between the two end supports arranged opposite each other.

[0011] Furthermore, the end support includes an arc-shaped cylindrical body, with the arc-shaped cylindrical bodies of the two oppositely arranged end supports bent in opposite directions. The end support also includes a straight cylindrical body disposed on the arc-shaped cylindrical body, and a connecting rod connecting the top of the arc-shaped cylindrical body and the top of the straight cylindrical body. The support rod is disposed in the straight cylindrical body between the two oppositely arranged end supports. The first stop bar is disposed at one end of the arc-shaped cylindrical body between the two oppositely arranged end supports. The other end of the arc-shaped cylindrical body of each end support is fixedly connected to the locking member through a support arm.

[0012] Furthermore, the drone protective cover also includes a second stop bar disposed on the bracket assembly, the second stop bar being connected between two end brackets disposed opposite to each other.

[0013] Furthermore, the end bracket is also provided with a quick-release structure, which includes a locking hole, and the second stop bar is connected between the locking holes of the two end brackets that are arranged opposite to each other.

[0014] Another embodiment of this utility model provides a drone, including a drone body and a drone protective cover with a tool-free quick-assembly and disassembly structure as described in any of the above embodiments.

[0015] This utility model embodiment provides a tool-free, quick-release structure for a drone protective cover, including a support assembly. The support assembly includes a collision protection component corresponding to the drone's propeller position and a locking component fixedly connected to the collision protection component. The locking component is used for fixed connection to the drone's propeller mounting arm. This allows the locking component to be directly connected to the drone's propeller mounting arm, further improving the structural stability of the support assembly while ensuring the propeller mounting arm has high structural strength. Furthermore, because this embodiment uses a locking component rather than a quick-release structure to achieve a fixed connection to the drone, the structural strength of the drone protective cover is effectively improved. This effectively prevents the protective cover from detaching due to impact and damaging the propellers under special conditions such as high-speed flight, thus ensuring drone flight safety.

[0024] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] When ordinal numbers such as "first" and "second" are mentioned in the embodiments of this utility model, unless they actually express the meaning of order according to the context, they should be understood as being used only for differentiation.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 utility model based on the specific circumstances.

[0027] Please refer to Figures 1 to 7 As shown, this embodiment provides a tool-free, quick-assembly and disassembly structure for a drone protective cover, including a bracket assembly. The bracket assembly includes a collision protection component corresponding to the position of the drone propeller, and a locking component 1 fixedly connected to the collision protection component. The locking component 1 is used to fix the drone propeller fixing arm 10.

[0028] As a specific solution rather than a limitation, the locking component 1 includes an annular fixing hole 14, the shape of which corresponds to the cross-sectional shape of the rotor blade fixing arm 10 of the UAV, and is used to be fitted onto the rotor blade fixing arm 10 of the UAV to achieve a fixed connection between the bracket assembly and the UAV.

[0029] As a specific solution and not a limitation, the locking component 1 includes an upper pipe clamp 11 and a lower pipe clamp 12, which are connected by a first pivot 13 so that the upper pipe clamp 11 and the lower pipe clamp 12 can be closed or opened relative to each other. The upper pipe clamp 11 and the lower pipe clamp 12 have notches formed at their respective positions. When the upper pipe clamp 11 and the lower pipe clamp 12 are closed relative to each other, the upper pipe clamp 11 and the lower pipe clamp 12 form the annular fixing hole 14 at the position of the notch.

[0030] In this embodiment, the shape of the locking component's housing corresponds to the shape of the drone propeller motor mount. It is fitted onto the side of the drone's propeller fixing arm 10 near the drone propeller motor mount and abuts against the motor mount, thereby achieving omnidirectional fixation of the locking component relative to the drone. For example, in this embodiment, the drone propeller is located below the motor mount, therefore, the drone protective cover in this embodiment is generally located above the drone propeller.

[0031] The upper pipe clamp 11 and the lower pipe clamp 12 can be locked by multiple longitudinal locking mechanisms, such as bolts or clamps. In this embodiment, as a preferred solution rather than a limitation, the lower pipe clamp 12 is provided with a first clearance groove 121, and the upper pipe clamp 11 is provided with a second clearance groove 111. The first clearance groove 121 and the second clearance groove 111 are connected and located on the side of the locking member 1. The locking member 1 also includes a latch 15 disposed in the first clearance groove 121 and the second clearance groove 111. The latch 15 is used to fix the upper pipe clamp 11 and the lower pipe clamp 12 so that the upper pipe clamp 11 and the lower pipe clamp 12 are kept in a closed state.

[0032] As a further improvement to the above solution, the lower pipe clamp 12 forms a second pivot 122 at the first clearance groove 121, the upper pipe clamp 11 forms a clearance groove 112 at the top of the second clearance groove 111, and a top stop surface 113 is formed at the bottom of the clearance groove 112. The locking buckle 15 includes a stud 151 and a nut 152. One end of the stud 151 is provided on the second pivot 122 and can rotate along the second pivot 122. The first clearance groove 121... 21 The width of the second clearance groove 111 is greater than that of the stud 151 so that the stud can exit or enter the first clearance groove 121 and the second clearance groove 111 based on the second pivot 122. The other end of the stud 152 is fitted with the nut 152. When the stud 152 rotates into the second clearance groove 111 based on the second pivot 122, the nut 152 slides into the clearance groove 112, and the nut 152 is detachably stopped on the top stop surface 113.

[0033] Please refer to Figures 2 to 4 As shown, when it is necessary to install the locking component 1 onto the rotor blade fixing arm of the UAV, the nut 152 can be loosened to disengage the nut 152 from the top stop surface 113. Then, the locking buckle 15 is rotated downwards to disengage the locking buckle 15 from the upper tube clamp 11. Then, the lower tube clamp 12 is rotated downwards to disengage the upper tube clamp 11 and the lower tube clamp 12. At this time, the upper tube clamp 11 and the lower tube clamp 12 are relatively open, so that the rotor blade fixing arm of the UAV can extend into the notch at the opposite position of the upper tube clamp 11 and the lower tube clamp 12. Then, based on... Figures 4 to 2 By reversing the steps, the locking component can be used to fix the drone's propeller fixing arm.

[0034] As a specific solution rather than a limitation, the number of anti-collision components in this embodiment corresponds to the number of drone propellers. Each anti-collision component includes two end supports 2 arranged opposite to each other, and also includes a strut 3 connected between the two end supports 2 arranged opposite to each other. The anti-collision component also includes a first stop bar 4 connected between the two end supports 2 arranged opposite to each other.

[0035] In this embodiment, the strut 3 is located inside the first stop bar 4. The strut 3 is a straight rod, and the first stop bar 4 is an arc-shaped stop bar. The strut 3 connects the two oppositely arranged end supports and provides structural support for the end supports 2, so as to balance and disperse the impact force of the first stop bar 4 when the UAV hits an object, thereby improving the safety of the UAV flight.

[0036] As a preferred embodiment rather than a limitation, the end support 2 includes an arc-shaped cylindrical body 21. The arc-shaped cylindrical bodies 21 of the two opposing end supports 2 are bent in opposite directions and correspond to the curvature of the first stop bar 4. The end support 2 also includes a straight cylindrical body 22 disposed on the arc-shaped cylindrical body 21, and a connecting rod 23 connecting the top of the arc-shaped cylindrical body 21 and the straight cylindrical body 22. The support rod 3 is disposed in the straight cylindrical body 22 between the two opposing end supports 2. The straight cylindrical body 22 is disposed on the inner end of the arc-shaped cylindrical body 21 relative to the locking member 1. The first stop bar 4 is disposed on the outer end of the arc-shaped cylindrical body 21 between the two opposing end supports 2. The inner end of the arc-shaped cylindrical body 21 of each end support 2 is fixedly connected to the locking member 1 through a support arm 5.

[0037] As a preferred, and not a limitation, solution, the tool-free, quick-assembly structure for the drone protective cover further includes a second retaining strip 6 mounted on the support assembly. The second retaining strip 6 connects to two opposing end supports 2. This arrangement ensures that, on the outer cross-section of the drone protective cover in the vertical projection direction, the first retaining strip 4 and the second retaining strip 6 are spaced apart in the circumferential direction, connecting all the anti-collision components into a more robust overall structure. In this structure, any impact from any direction will be transmitted through the first retaining strip 4, the second retaining strip 5, the corresponding end supports 2, and the locking element 1 to the drone's propeller fixing arm 10, thus balancing and dispersing the impact force, reducing excessive local stress on the drone protective cover, and improving the overall structural strength and impact resistance of the drone protective cover.

[0038] As a specific solution and not a limitation, the first stop bar 4 in this embodiment can be a plastic part or a metal part, and the second stop bar 4 can be a flexible part, and the material can be metal wire or plastic wire with high toughness.

[0039] In this embodiment, the end bracket 2 is further provided with a quick-release structure 8, which includes a locking hole 7. The second stop bar 6 is connected between the locking holes 7 of the two end brackets 2 that are arranged opposite to each other. Specifically, the quick-release structure 8 can be an elastic reset locking device. The quick-release structure 8 is set and fixed in the through hole of the arc-shaped cylinder 21. When the quick-release structure 8 is pressed, the internal elastic element is squeezed, and the elastic reset locking device sinks down, so that the locking hole 7 is in an open and relaxed state, so as to insert the second stop bar 4 or adjust the tightness of the second stop bar 4. When the quick-release structure 8 is stopped, the elastic reset locking device is reset under the action of the internal elastic element, and the elastic reset locking device is lifted up, so that the locking hole 7 is in a locked state, so that the quick-release structure 8 locks the second stop bar 6, thereby fixing the second stop bar 6.

[0040] This utility model embodiment provides a tool-free, quick-release structure for a drone protective cover, including a support assembly. The support assembly includes a collision protection component corresponding to the drone's propeller position and a locking component fixedly connected to the collision protection component. The locking component is used for fixed connection to the drone's propeller mounting arm. This allows the locking component to be directly connected to the drone's propeller mounting arm, further improving the structural stability of the support assembly while ensuring the propeller mounting arm has high structural strength. Furthermore, because this embodiment uses a locking component rather than a quick-release structure to achieve a fixed connection to the drone, the structural strength of the drone protective cover is effectively improved. This effectively prevents the protective cover from detaching due to impact and damaging the propellers under special conditions such as high-speed flight, thus ensuring drone flight safety.
