[0037] Unmanned aerial vehicles (UAVs) are aircraft that perform flight missions through wireless remote control or autonomous control systems and are widely used in fields such as aerial photography, surveying, logistics, and plant protection.

[0038] Currently, during drone use, the drone's base generally lacks a support structure to support the connector, leaving the connector suspended in mid-air. When the drone generates high-frequency vibrations during flight and these vibrations are transmitted to the connector, the connector is prone to vibration or shaking, leading to loosening, detachment, or breakage of the connection between the connector and the cable. This can cause the drone to lose control and create safety hazards.

[0039] In view of this, the present invention provides an embodiment of connector 4 assembly 100, which can not only support the main body of the drone, but also reduce the probability of loosening at the connection between connector 4 and cable.

[0040] To facilitate the reader's understanding of the concept of this utility model embodiment, the specific structure of the connector 4 component 100 is described below:

[0041] Please see Figures 1 to 3 The connector 4 assembly 100 includes a base 1, a snap-fit ​​2, a fastener 3, and a connector 4; the base 1 is used to support the main body of the drone; the snap-fit ​​2 is provided with a snap-fit ​​part 21; the fastener 3 passes through the snap-fit ​​2 and is connected to the base 1, and the fastener 3 fixes the snap-fit ​​2 to the base 1; the connector 4 snaps into the snap-fit ​​part 21, and the connector 4 is used for electrical connection with the main body of the drone.

[0042] In the above manner, the snap-fit ​​2 and fastener 3 in this embodiment of the present invention form a support structure for supporting the connector 4, so that the connector 4 can not only be indirectly fixed to the base 1 through the snap-fit ​​2 and fastener 3, thereby improving the stability of the connector 4, reducing the shaking of the connector 4 due to high-frequency vibration during flight, reducing the probability of loosening at the connection between the connector 4 and the cable, reducing the probability of the drone going out of control, and reducing the probability of causing safety hazards, but also form a detachable connection through the snap-fit ​​2 and fastener 3, enabling quick assembly and disassembly of the connector 4, which is helpful for the maintenance and replacement of the connector 4.

[0043] Regarding the base 1 described above, please refer to some embodiments. Figures 1 to 3The base 1 is a pipe clamp seat. The base 1 is provided with a main body 11, a pipe clamp 12 and an extension 13. The main body 11, the pipe clamp 12 and the extension 13 are integrally formed. The pipe clamp 12 is located below the main body 11 and the extension 13 is located on the side of the main body 11. The main body 11 is used to support the main body of the UAV. The pipe clamp 12 is used to clamp the components of the UAV (e.g., arms, frames, sensor brackets, plant protection spray pipes or plant protection nozzles, etc.). The extension 13 is used for connecting the card connector 2 and the fastener 3.

[0044] Furthermore, in some embodiments, please refer to Figure 3 The base 1 has a plurality of mounting holes 14 on the main body 11. The mounting holes 14 are arranged in an array and extend from the top to the bottom of the main body 11. The mounting holes 14 are all stepped. The mounting holes 14 are used for screws to pass through and screw into the drone body so that the drone body is fixed to the main body 11. The cross-section of the clamp part 12 is arc-shaped. The cross-section here refers to the cross-section of the clamp part 12 along the length direction. The base 1 has a plurality of through holes 15 on the clamp part 12. The through holes 15 are used to release the air pressure between the clamp part 12 and the drone's rod when the clamp part 12 clamps the drone's rod. The through holes 15 are used to allow the drone's rod to be exposed to air for heat dissipation when the clamp part 12 clamps the drone's rod. The through holes 15 are also used to reduce the weight of the base 1 to achieve the purpose of weight reduction.

[0045] Furthermore, in some embodiments, please refer to Figure 3 The clamping part 12 includes a first clamp 121 and a second clamp 122, which are arranged opposite to each other. A gap is formed between the first clamp 121 and the second clamp 122 on the side away from the main body 11. The clamping part 12 has a through first opening 16 in the first clamp 121 and a through second opening 17 in the second clamp 122. Both the first opening 16 and the second opening 17 are stepped and aligned. The first opening 16 is used for a screw to pass through and extend to the second opening 17. The second opening 17 is used to receive a nut so that the nut and the screw are screwed together and fixed, thereby eliminating the gap between the first clamp 121 and the second clamp 122 and realizing clamping.

[0046] In some embodiments, the snap-fit ​​component 2 is made of plastic, metal, or alloy. For example, in some embodiments, the snap-fit ​​component 2 is made of aluminum alloy, copper alloy, or nickel alloy, etc.

[0047] Regarding the aforementioned card connector 2, in some embodiments, please refer to... Figure 1 and Figure 2The latching portion 21 includes a first latching portion 211 and a second latching portion 212, which are arranged at a preset angle. The connector 4 includes a first connector 41 and a second connector 42, with the first connector 41 latching with the first latching portion 211 and the second connector 42 latching with the second latching portion 212. In this manner, the first latching portion 211 and the second latching portion 212 can expand the latching function of the latching portion 21, allowing it to adapt to latching connectors 4 with different shapes and structures. Furthermore, by arranging the first latching portion 211 and the second latching portion 212 at a preset angle, the first latching portion 211 and the second latching portion 212 can be oriented in different positions, reducing the probability of interference between the first connector 41 and the second connector 42.

[0048] It should be noted that, please refer to [link / reference needed]. Figure 1 and Figure 2 The included angle between the first latching portion 211 and the second latching portion 212 is greater than or equal to zero degrees and less than or equal to 180 degrees. It should also be noted that, as a more preferred option, the included angle between the first latching portion 211 and the second latching portion 212 is greater than or equal to ninety degrees and less than or equal to 180 degrees. For example, in some embodiments, please refer to... Figure 4 The preset included angle between the first latching portion and the second latching portion is zero degrees, meaning the first latching portion and the second latching portion are arranged in parallel; or, in other embodiments, please refer to... Figure 5 The preset included angle between the first snap-fit ​​part and the second snap-fit ​​part is 90 degrees, that is, the first snap-fit ​​part and the second snap-fit ​​part are perpendicular.

[0049] Furthermore, in some embodiments, please refer to Figure 5 The snap-fit ​​part 21 is provided with a first snap-fit ​​claw 213. The first snap-fit ​​claw 213 is arc-shaped and the claw opening of the first snap-fit ​​claw 213 faces the base 1. The first connector 41 snaps into the first snap-fit ​​claw 213, and the first snap-fit ​​claw 213 constitutes the first snap-fit ​​part 211.

[0050] Furthermore, in some embodiments, please refer to Figure 5 The latching part 21 is provided with a second latch 214. The second latch 214 is arc-shaped. The jaw of the second latch 214 is set at a preset angle with the jaw of the first latch 213. The second connector 42 is latched onto the second latch 214. The second latch 214 constitutes the second latching part 212.

[0051] For the fastener 3 described above, please refer to some embodiments. Figures 1 to 3 The fastener 3 passes through the snap-fit ​​2 and is connected to the extension 13, thus fixing the snap-fit ​​2 to the extension 13.

[0052] Furthermore, in some embodiments, please refer to Figures 1 to 3Along the first direction, the projection of the extension 13 overlaps with the projection of the first latching portion 211, meaning the first latching portion 211 is located directly below the extension 13. The projection of the extension 13 is offset from the projection of the second latching portion 212, meaning the second latching portion 212 is located obliquely below the extension 13 away from the base 1. The first direction is the height direction of the base 1. This optimizes the positions of the first latching portion 211 and the second latching portion 212, reducing the probability of interference between the first connector 41 and the second connector 42. Furthermore, by having the projection of the extension 13 overlap with the projection of the first latching portion 211 and the projection of the extension 13 offset from the projection of the second latching portion 212, the latching member 2 can at least partially overlap with the base 1 along the first direction, improving the structural compactness of the connector 4 assembly 100 and helping to reduce the overall volume of the connector 4 assembly 100.

[0053] Furthermore, in some embodiments, please refer to Figures 1 to 3 The base 1 has a screw hole 18 in the extension 13; the snap-fit ​​part 2 has a connecting part 22, and a through hole 23 in the connecting part 22, which is aligned with the screw hole 18; the fastener 3 has a screwing part 31 and a tightening part 32, the screwing part 31 passes through the through hole 23 and is screwed into the screw hole 18, and the tightening part 32 abuts against the side of the snap-fit ​​part 2 away from the base 1. In this way, the snap-fit ​​part 2 is detachably connected to the base 1 by the fastener 3, which facilitates the maintenance and replacement of the snap-fit ​​part 2.

[0054] Regarding the connector 4 component 100 described above, in some embodiments, please refer to... Figure 6 and Figure 7 The connector 4 assembly 100 further includes a first anti-slip member 5, which is disposed between the first latching portion 211 and the first connector 41. The first anti-slip member 5 is annularly arranged and sleeved on the first connector 41, and latched onto the first latching portion 211. And / or, the connector 4 assembly 100 further includes a second anti-slip member 3, which is disposed between the second latching portion 212 and the second connector 42. The second anti-slip member 3 is annularly arranged and sleeved on the second connector 42, and latched onto the second latching portion 212. Through the above methods, the sliding friction between the first latching portion 211 and the first connector 41, and / or the sliding friction between the second latching portion 212 and the second connector 42, can be increased, thereby reducing the probability of slippage of the first connector 41 and / or the second connector 42, and thus improving the latching stability of the first connector 41 and / or the second connector 42.

[0055] For the connector 4-component 100 described above, please refer to other embodiments. Figure 8 and Figure 9The connector 4 assembly 100 also includes a third anti-slip element 7, which at least partially covers the surfaces of the first latching portion 211 and the second latching portion 212. Both the first connector 41 and the second connector 42 are at least partially in contact with the third anti-slip element 7. In this manner, the third anti-slip element 7 covers the first latching portion 211 and the second latching portion 212, which not only increases the sliding friction between the first latching portion 211 and the first connector 41, and also increases the sliding friction between the second latching portion 212 and the second connector 42, but also reduces the intrusion of dust or debris between the first latching portion 211 and the first connector 41, and between the second latching portion 212 and the second connector 42, thereby improving the reliability of the anti-slip mechanism.

[0056] Furthermore, in some embodiments, the first anti-slip component 5, the second anti-slip component 6, and the third anti-slip component 7 are all made of silicone.

[0057] This utility model embodiment provides a connector 4 assembly 100, including a base 1, a snap-fit ​​component 2, a fastener 3, and a connector 4. The base 1 supports the main body of a drone. The snap-fit ​​component 2 is provided with a snap-fit ​​portion 21. The fastener 3 passes through the snap-fit ​​component 2 and is connected to the base 1, fixing the snap-fit ​​component 2 to the base 1. The connector 4 snaps into the snap-fit ​​portion 21 and is used for electrical connection with the main body of the drone. Through the above method, the connector 4 in this utility model embodiment can not only be indirectly fixed to the base 1 through the snap-fit ​​component 2 and the fastener 3, improving the stability of the connector 4, reducing the shaking of the connector 4 due to high-frequency vibration during flight, reducing the probability of loosening at the connection between the connector 4 and the cable, reducing the probability of drone loss of control, and reducing the probability of causing safety hazards, but also form a detachable connection through the snap-fit ​​component 2 and the fastener 3, enabling quick assembly and disassembly of the connector 4, which is helpful for the maintenance and replacement of the connector 4.

[0058] This utility model also provides an embodiment of a drone, which includes a drone body and the aforementioned connector 4 assembly 100. The drone body is connected to the base 1 of the connector 4 assembly 100, and the drone body is electrically connected to the connector 4 of the connector 4 assembly 100.
