Description

Technical Field

[0001] The present application relates to the technical field of unmanned aerial vehicles, and particularly relates to a waterproof structure, a mission payload, and an unmanned aerial vehicle system. Background Art

[0002] In related technologies, in order to complete tasks in different application scenarios, mission payloads with different functions are usually carried on unmanned aerial vehicles. Since there may be a risk of the unmanned aerial vehicle crashing due to various reasons during flight in the air, in order to protect the unmanned aerial vehicle and reduce the damage caused by the crash of the unmanned aerial vehicle, a parachute is usually provided on the mission payload to provide buffering, thereby slowing down the falling speed of the unmanned aerial vehicle. At the same time, to ensure that the parachute can be normally opened and ejected out of the parachute compartment, the connection method between the hatch cover and the housing provided with the parachute compartment is usually set as a simple and detachable connection structure, resulting in poor sealing performance of the parachute compartment. When the unmanned aerial vehicle is working at high altitude outdoors in rainy weather, rainwater may enter the interior of the mission payload through the gap between the hatch cover and the housing, causing damage to the electronic devices inside the mission payload and affecting the operation of the mission payload. Summary of the Utility Model

[0003] The present application aims to at least solve one of the technical problems existing in the prior art. For this reason, the present application proposes a waterproof structure that can improve the waterproof and sealing performance of the parachute compartment while satisfying the requirement that the parachute can be opened and ejected out of the parachute compartment.

Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0039] Please refer to Figures 1 to 5 , in a first aspect, an embodiment of the present application provides a waterproof structure 100, including a housing 10 and a hatch cover 20. The housing 10 is provided with a parachute compartment 11, a diversion groove 12, and a drainage channel 13. The parachute compartment 11 has a first opening. The diversion groove 12 is arranged around the outer periphery of the parachute compartment 11, and the diversion groove 12 has a second opening. The drainage channel 13 communicates with the bottom of the diversion groove 12. The drainage channel 13 has a water outlet 130 communicating with the outside of the housing 10. The hatch cover 20 is detachably connected to the housing 10 to seal or open the first opening and the second opening.

[0040] In this way, by arranging the diversion groove 12 around the outer periphery of the parachute compartment 11 and making the drainage channel 13 with the water outlet 130 communicate with the bottom of the diversion groove 12, and the hatch cover 20 is detachably connected to the housing 10, when the hatch cover 20 is disconnected from the housing 10, the parachute in the parachute compartment 11 can be smoothly opened and ejected. When the hatch cover 20 is connected to the housing 10, the hatch cover 20 seals the first opening of the parachute compartment 11 and the second opening of the diversion groove 12. Thus, on the one hand, by sealing the parachute compartment 11 with the hatch cover 20, it can prevent rainwater (or other liquids) from entering the parachute compartment 11 and the diversion groove 12. On the other hand, when rainwater enters the waterproof structure 100 through the gap between the hatch cover 20 and the housing 10, the rainwater first enters the diversion groove 12 through the second opening, then enters the drainage channel 13 through the bottom of the diversion groove 12, and finally is discharged from the water outlet 130 of the drainage channel 13 out of the housing 10. That is, after the rainwater enters the waterproof structure 100, it can be discharged from the channel around the outer periphery of the parachute compartment 11 and will not enter the parachute compartment 11, thereby effectively improving the waterproof and sealing performance of the parachute compartment 11.

[0041] Optionally, the waterproof structure 100 has opposite first end 101 and second end 102 along its own length direction. The diversion groove 12 extends obliquely downward from the first end 101 to the second end 102, and the drainage channel 13 is connected to one side of the diversion groove 12 close to the second end 102. Thereby, it is beneficial to guide the rainwater in the diversion groove 12 to flow into the drainage channel 13, so as to drain the rainwater in time and reduce the accumulation of rainwater in the waterproof structure 100.

[0042] Optionally, the drainage channel 13 is formed by the side wall of the umbrella compartment 11 recessing away from the diversion groove 12, and the depth of the drainage channel 13 is greater than the depth of the diversion groove 12, so as to ensure that the rainwater in the diversion groove 12 can be discharged through the drainage channel 13.

[0043] Please refer to Figure 2 、 Figure 3 and Figure 6 In some embodiments, the hatch cover 20 is provided with a first water baffle 21 and a second water baffle 22. The first water baffle 21 and the second water baffle 22 are arranged at intervals, and when the hatch cover 20 is connected to the outer shell 10, the first water baffle 21 is located in the umbrella compartment 11, and the second water baffle 22 is located in the diversion groove 12.

[0044] In this way, by providing the first water baffle 21 and the second water baffle 22, it can not only be positioned when the hatch cover 20 is installed, so as to facilitate the assembly of the hatch cover 20 and the outer shell 10, but also improve the sealing performance at the connection between the hatch cover 20 and the outer shell 10 to block rainwater from entering the umbrella compartment 11, thereby being beneficial to improving the sealing and waterproof performance of the umbrella compartment 11.

[0045] Optionally, considering that the diversion groove 12 is used to guide the flow of rainwater and its internal space is small, while the space in the umbrella compartment 11 is larger than the space in the diversion groove 12. Based on this, the first water baffle 21 is provided with a first buckle portion 211, and the side wall of the umbrella compartment 11 is provided with a second buckle portion 111. The first buckle portion 211 and the second buckle portion 111 are buckled and connected.

[0046] In this way, by buckling and connecting the first water baffle 21 with the side wall of the umbrella compartment 11, the space of the umbrella compartment 11 can be reasonably utilized to ensure the sealing performance of the umbrella compartment 11 while ensuring the volume of the diversion groove 12 that can accommodate rainwater, so as to be beneficial to reducing the risk of rainwater entering the umbrella compartment 11 after entering the diversion groove 12 from the gap between the hatch cover 20 and the outer shell 10. At the same time, the hatch cover 20 and the outer shell 10 are connected by a buckling method, which is beneficial to the disassembly and assembly of the hatch cover 20. When the parachute is installed in the umbrella compartment 11, it is beneficial to drive the hatch cover 20 and the outer shell 10 to disconnect when the parachute pops out, so as to ensure that the parachute can be normally opened and pop out of the umbrella compartment 11.

[0047] Optionally, one of the first latching portion 211 and the second latching portion 111 may be a protruding latch, and the other may be a groove or a through hole, which is conducive to simplifying the connection method between the housing 10 and the hatch cover 20, so as to facilitate the disassembly and assembly of the housing 10 and the hatch cover 20.

[0048] Optionally, a reinforcing rib is provided on the side of the first water baffle 21 away from the first seal 30. The reinforcing rib is used to support the first latching portion 211 to improve the strength of the first water baffle 21 at the latching connection position, thereby improving the structural reliability of the first water baffle 21. At the same time, since the reinforcing rib is located on the side of the first water baffle 21 away from the first seal 30, it can also ensure that the space between the first water baffle 21 and the second water baffle 22 is not interfered, so as to facilitate the cooperation between the hatch cover 20 and the housing 10 and avoid the interference between the reinforcing rib and the side wall of the umbrella compartment 11.

[0049] It can be understood that in some other embodiments, the connection method between the hatch cover 20 and the housing 10 can also be any one of bonding, pin connection, or screw connection, etc.

[0050] In some embodiments, the waterproof structure 100 further includes a first seal 30. The first seal 30 is disposed between the hatch cover 20 and the side wall of the umbrella compartment 11 and abuts against the top of the side wall, and the first seal 30 is hermetically filled in the space between the first water baffle 21 and the second water baffle 22. Thereby, the gap between the hatch cover 20 and the side wall of the umbrella compartment 11 can be hermetically sealed, which is conducive to blocking rainwater from entering the umbrella compartment 11, thereby improving the sealing performance of the umbrella compartment 11.

[0051] Optionally, the first seal 30 is provided with a positioning groove 31, and a positioning member is provided on the side of the second water baffle 22 facing the first seal 30. The positioning member is snap-fitted into the positioning groove 31. Thereby, it is not only conducive to the positioning of the first seal 30, so as to facilitate the installation of the first seal 30 on the hatch cover 20 and improve the assembly convenience of the waterproof structure 100, but also improves the connection reliability between the first seal 30 and the hatch cover 20 to ensure the sealing effect of the first seal 30 on the umbrella compartment 11. In addition, by providing the positioning member, the second water baffle 22 can also be supported, which is conducive to improving the structural strength of the second water baffle 22.

[0052] It can be understood that in some other embodiments, the positioning member can also be provided on the side of the first water baffle 21 facing the first seal 30.

[0053] Optionally, the first seal 30 can be an O-ring, which is conducive to the assembly of the first seal 30.

[0054] It can be understood that in some other embodiments, the first seal 30 can also be any one of a sealing foam, a sealant, or a soft filler, etc.

[0055] Optionally, the positioning member can be a positioning rib, a positioning column, a positioning block, etc., which can be specifically set according to actual requirements and are not limited here.

[0056] In some embodiments, the edge of the hatch cover 20 extends downwardly and obliquely in the direction from the first water baffle 21 to the second water baffle 22. This can facilitate the flow of rainwater on the hatch cover 20, reduce the accumulation of rainwater on the hatch cover 20, so as to reduce the rainwater adhering to the waterproof structure 100, reduce the weight of the waterproof mechanism, and further facilitate ensuring the flight reliability of the drone system and avoiding the situation of the center of gravity imbalance of the drone system caused by the accumulation of rainwater on the waterproof structure 100.

[0057] Please refer to Figure 3 , Figure 7 and Figure 8 Second, the present application also provides a mission payload 200, including a parachute and the waterproof structure 100 described in the first aspect above. The parachute is installed in the parachute compartment 11, and when the parachute is opened, it drives the hatch cover 20 to disconnect from the outer shell 10, so that the parachute pops out of the parachute compartment 11 through the first opening.

[0058] Thus, while satisfying that the parachute can be opened and popped out of the parachute compartment 11, the waterproof and sealing performance of the parachute compartment 11 can also be improved.

[0059] It can be understood that since the mission payload 200 includes the waterproof structure 100 described in the first aspect above, the mission payload 200 has the beneficial effects of the waterproof structure 100 described in the first aspect above, which will not be elaborated here.

[0060] In some embodiments, the mission payload 200 further includes a control unit and two speakers 201. The parachute and the two speakers 201 are both electrically connected to the control unit. The outer shell 10 is provided with an installation cavity and two sound transmission channels. The control unit is installed in the installation cavity. The two sound transmission channels are respectively located on both sides of the parachute compartment 11, and the two speakers 201 correspond to the two sound transmission channels one by one. The speaker 201 is installed at one end of the sound transmission channel close to the water outlet 130, and the water outlet 130 is located between the speaker 201 and the parachute.

[0061] In this way, by setting the speaker 201 and the sound transmission channel, the mission payload 200 has a broadcasting function to enrich the functions of the mission payload 200. By setting the speaker 201 at one end of the sound transmission channel close to the water outlet 130, it is beneficial to ensure the size of the sound output end of the sound transmission channel, thereby facilitating increasing the broadcasting distance. At the same time, by setting the water outlet 130 between the speaker 201 and the parachute, the space of the outer shell 10 can be reasonably utilized, and the path of the outer shell 10 for rainwater drainage can be shortened to improve the drainage efficiency of the mission payload 200.

[0062] Optionally, considering that the two sound transmission channels are located on both sides of the umbrella compartment 11, both speakers 201 are electrically connected to the control unit. Based on this, the installation cavity is located below the umbrella compartment 11, and the water outlet 130 is located above the installation cavity. The housing 10 is provided with a wiring groove 202, and a wiring port 203 is provided through the bottom of the wiring groove 202. The wiring port 203 communicates with the installation cavity. The connecting wires of the speakers 201 extend into the installation cavity through the wiring groove 202 and the wiring port 203 and are connected to the control unit. The mission payload 200 further includes a second seal, and the second seal is installed between the wiring groove 202 and the speaker 201.

[0063] Thus, while reasonably utilizing the space of the housing 10, the sealing performance of the installation cavity can be improved to avoid the situation that rainwater enters the installation cavity and damages the control unit, which is beneficial to ensuring the reliability of the electronic components in the installation cavity, and further improving the reliability of the mission payload 200.

[0064] In a third aspect, the present application further provides an unmanned aerial vehicle system (not shown), including an unmanned aerial vehicle (not shown) and the mission payload 200 as described in the second aspect above, and the mission payload 200 is carried on the unmanned aerial vehicle.

[0065] It can be understood that since the unmanned aerial vehicle system includes the mission payload 200 as described in the second aspect above, therefore, the unmanned aerial vehicle system has the beneficial effects of the mission payload 200 as described in the second aspect above, which will not be elaborated here.

[0066] The embodiments of the present application have been described in detail above in conjunction with the drawings, but the present application is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present application within the scope of knowledge possessed by those of ordinary skill in the art. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
