Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical connectors, and in particular to a connector and a plant protection unmanned aerial vehicle. BACKGROUND

[0002] The connector can be widely applied to various types of vehicles, communications, computers and other consumer electronics, industries, transportation and other fields. The various types of vehicles that can be applied include new energy vehicles, electric bicycles, electric motorcycles, electric scooters and the like. The connector plug and the connector socket, as key components, can build a bridge between circuits, allowing current to flow and enabling the circuit to achieve the intended function. However, the existing connector has poor sealing performance. CONTENT OF THE INVENTION

[0003] The present application aims to provide a connector and a plant protection unmanned aerial vehicle.

[0004] The present application provides a connector, which comprises a first glue core and a sealing member. The first glue core comprises a connecting portion. The sealing member comprises a supporting ring and an elastic sealing portion. The supporting ring is sealingly connected to the connecting portion and surrounds the connecting portion. The sealing portion is connected to the supporting ring and is used to seal the plug connection between the connector and an external mating connector. There is a relief groove between the sealing portion and the supporting ring. When the connector and the external mating connector are plugged together, the sealing portion floats towards or away from the relief groove along the plugging direction.

[0005] The present application also provides a plant protection unmanned aerial vehicle, which comprises a body and a connector. The connector is mounted on the body.

[0006] In the present application, the connector on the plant protection unmanned aerial vehicle is used to plug with an external mating connector. When the plant protection unmanned aerial vehicle is flying in the air, the connector and the mating connector have two movement trends, i.e. combination or separation. During the process of spraying pesticide, pesticide solution is easy to remain on the connector and the mating connector. During the flight of the plant protection unmanned aerial vehicle, the pesticide solution is easy to enter the gap between the connector and the mating connector, resulting in short circuit, water accumulation and corrosion, etc.

[0007] Since the sealing portion is elastic and there is a relief groove between the sealing portion and the supporting ring, when the connector and the mating connector are plugged together, the mating connector sealingly abuts against the sealing portion, the sealing portion elastically deforms, and the sealing portion floats towards the relief groove along the plugging direction. When the plant protection unmanned aerial vehicle is working, if the connector and the mating connector have a combination movement trend, the mating connector approaches the connector, the mating connector continues to sealingly abut against the sealing portion, and the sealing portion continues to float towards the relief groove along the plugging direction. At this time, the deformation of the sealing portion is larger, and the sealing effect is better.

[0008] If a separation movement tendency occurs between the connector and the mating connector, the mating connector is away from the connector, the mating connector is away from the sealing part, the sealing part rebounds, and the sealing part will float away from the escape slot in the plug-in direction. As long as the displacement amount of the separation of the connector and the mating connector is less than the floating amount of the sealing part in the plug-in direction, the sealing part will not fully rebound, and the sealing part can always abut against the mating connector in a sealed manner, thereby ensuring that the connector and the mating connector are always in a sealed state, which is beneficial to prevent the short circuit, water accumulation and corrosion and the like caused by the medicine entering the gap between the connector and the mating connector.

The mounting plate 24 of the mating connector 20 sealingly abuts against the first sealing ring 1421 of the sealing part 142 away from the side of the supporting ring 1412, the opening of the through groove 1422 is closed, thereby preventing liquid from entering the accommodating groove 1113 from the through groove 1422. It can be understood that the sealing part 142 is used to seal the plug of the connector 10 and the external mating connector 20. In other embodiments, the mounting plate 24 can be omitted, and the sealing part 142 sealingly abuts against the second glue core 21.

[0056] In the prior art, due to the high frequency of plugging and unplugging of the connector 10 and the mating connector 20 on the plant protection unmanned aerial vehicle, the stability of the connection between the connector 10 and the mating connector 20 is poor after long-term use. When the plant protection unmanned aerial vehicle is flying in the air, the combination or separation movement trend between the connector 10 and the mating connector 20 is generated. During the process of spraying pesticide by the plant protection unmanned aerial vehicle, pesticide solution is easy to remain on the connector assembly 100. During the flight of the plant protection unmanned aerial vehicle, the pesticide solution is easy to enter the gap between the connector 10 and the mating connector 20, causing the connector assembly 100 to appear short circuit, water accumulation and corrosion and the like.

[0057] In the embodiment, the sealing part 142 has elasticity, and the sealing part 142 and the support ring 1412 have the avoiding groove 143. When the mounting plate 24 of the mating connector 20 is sealingly abutted against the first sealing ring 1421 of the sealing part 142, the first sealing ring 1421 is elastically deformed, and the first sealing ring 1421 will float along the Z-axis direction towards the avoiding groove 143.

[0058] When the plant protection unmanned aerial vehicle is working, if the combination movement trend between the connector 10 and the mating connector 20 is generated, the mating connector 20 is close to the connector 10, the mounting plate 24 continues to sealingly abut against the first sealing ring 1421, and the first sealing ring 1421 will continue to float along the Z-axis direction towards the avoiding groove 143. At this time, the deformation amount of the first sealing ring 1421 is larger, and the sealing effect is better.

[0059] If the separation movement trend between the connector 10 and the mating connector 20 is generated, the mating connector 20 is away from the connector 10, the mounting plate 24 is away from the first sealing ring 1421, the first sealing ring 1421 rebounds, and the first sealing ring 1421 will float along the Z-axis direction away from the avoiding groove 143. As long as the displacement amount of the separation between the connector 10 and the mating connector 20 is less than the floating amount of the first sealing ring 1421 along the Z-axis direction, the first sealing ring 1421 will not completely rebound, and the first sealing ring 1421 can always sealingly abut against the mounting plate 24, thereby ensuring that the connector assembly 100 is always in a sealed state, which is beneficial to prevent the pesticide solution from entering the connector assembly 20 to cause short circuit, water accumulation and corrosion and the like.

[0060] In the embodiment, by gradually increasing or decreasing the caliber of the first sealing ring 1421 along the Z-axis direction, when the mounting plate 24 abuts against the first sealing ring 1421, the elasticity of the first sealing ring 1421 is better, the rebound trend of the first sealing ring 1421 is greater, the first sealing ring 1421 is more fitted with the mounting plate 24, and the sealing effect is improved.

[0061] In this embodiment, by arranging the support ring 1412, when the first sealing ring 1421 is abutted, the support ring 1412 can support the first sealing ring 1421 to prevent the first sealing ring 1421 from being damaged by being abutted too much. In addition, the support ring 1412 can provide support force to the first sealing ring 1421, so that the first sealing ring 1421 is more closely attached to the mounting plate 24, and the sealing effect is better.

[0062] In this embodiment, the connecting flange 1112 of the connecting portion 111 is positioned in the fixing ring groove 1418. Understandably, the fixing portion 141 of the sealing member 14 wraps the connecting flange 1112 of the connecting portion 111, the structure is compact, and the connection between the sealing member 14 and the connecting portion 111 is more stable, and the sealing effect is better.

[0063] Please refer to Figure 14 The second embodiment of the present application provides a connector assembly 100, which is different from the connector assembly 100 provided by the first embodiment of the present application in that the structure of the sealing portion 142 of the sealing member 14 is different. Specifically, on the basis of the first embodiment, the sealing portion 142 is further provided with a second sealing ring 1423, one side of the second sealing ring 1423 being connected to the side of the support ring 1412 away from the fixing ring 1411. The second sealing ring 1423 is located in the space enclosed by the first sealing ring 1421, and along the Z-axis direction, the side of the first sealing ring 1421 away from the support ring 1412 and the side of the second sealing ring 1423 away from the support ring 1412 are away from each other, and the second sealing ring 1423 and the support ring 1412 have an avoiding groove 143 therebetween. Understandably, the cross section of the sealing portion 142 is V-shaped. In this embodiment, when the mating connector 20 is inserted into the connector 10, the mounting plate 24 is sealingly abutted against the first sealing ring 1421 and the second sealing ring 1423, respectively. By increasing the second sealing ring 1423, the second sealing ring 1423 can also float along the Z-axis direction towards or away from the avoiding groove 143, the abutted area between the sealing portion 142 and the mounting plate 24 is increased, and thus the sealing effect is improved. The state change of the second sealing ring 1423 when it floats is the same as that of the first sealing ring 1421, and specific descriptions can be referred to the related descriptions of the first sealing ring 1421, which will not be repeated here.

[0064] Please refer to Figure 15The third embodiment of the present application provides a connector assembly 100, which is different from the connector assembly 100 provided by the first embodiment in that the structure of the sealing part 142 of the sealing member 14. Specifically, on the basis of the first embodiment, the sealing part 142 is further provided with a third sealing ring 1424, one side of the third sealing ring 1424 being connected to the side of the first sealing ring 1421 away from the support ring 1412. The caliber of one of the first sealing ring 1421 and the third sealing ring 1424 gradually increases along the Z-axis direction, and the caliber of the other gradually decreases along the Z-axis direction. For example, the caliber of the first sealing ring 1421 gradually decreases along the positive direction of the Z-axis, and the caliber of the third sealing ring 1424 gradually increases along the positive direction of the Z-axis.

[0065] In the present embodiment, by providing the third sealing ring 1424 and connecting one side of the third sealing ring 1424 to the side of the first sealing ring 1421 away from the support ring 1412, when the connector 20 is plugged with the connector 10, the mounting plate 24 abuts against the side of the third sealing ring 1424 away from the first sealing ring 1421, the first sealing ring 1421 floats along the Z-axis direction towards or away from the avoiding groove 143, the third sealing ring 1424 floats along the Z-axis direction towards or away from the first sealing ring 1421, and the overall floating amount of the sealing part 142 along the Z-axis direction is larger. Even if the displacement amount of the connector 10 or the mating connector 20 when separated is larger, the sealing part 142 can still abut against the mounting plate 24 in a sealed manner, and the sealing effect is better.

[0066] In other embodiments, the sealing part 142 can further be provided with a fourth sealing ring 1425 and a fifth sealing ring 1426, one side of the fourth sealing ring 1425 being connected to the side of the third sealing ring 1424 away from the first sealing ring 1421, and one side of the fifth sealing ring 1426 being connected to the side of the fourth sealing ring 1425 away from the third sealing ring 1424. Along the positive direction of the Z-axis, the caliber of the first sealing ring 1421 gradually decreases, the caliber of the third sealing ring 1424 gradually increases, the caliber of the fourth sealing ring 1425 gradually decreases, and the caliber of the fifth sealing ring 1426 gradually increases. Understandably, the number of sealing rings is multiple, and the process of elastic deformation of the sealing part 142 formed by the multiple sealing rings connected in sequence is similar to that of a spring. When the connector 10 or the mating connector 20 floats up and down, the sealing part 142 can contract and expand up and down.

[0067] Please refer to Figure 16The fourth embodiment of the present application provides the connector assembly 100, which is different from the connector assembly 100 provided by the first embodiment in that the structure of the sealing part 142 of the sealing member 14 is different. Specifically, in the present embodiment, the first sealing ring 1421 is bent away from the side of the supporting ring 1412 and towards the connecting part 111. The sealing part 142 is further provided with an abutting ring 1427, and the outer edge of the abutting ring 1427 is fixedly connected to the side of the first sealing ring 1421 away from the supporting ring 1412. In the Z-axis direction, the abutting ring 1427 is spaced from the supporting ring 1412. The abutting ring 1427 is perpendicular to the Z-axis direction, and in other embodiments, the abutting ring 1427 can also be not perpendicular to the Z-axis direction, and the abutting ring 1427 can be slightly inclined relative to the X-axis direction. When the mating connector 20 is inserted into the connector 10, the mounting plate 24 abuts against the abutting ring 1427 in a sealing manner, the first sealing ring 1421 is bent towards the avoiding groove 143, the first sealing ring 1421 generates elastic force, and the first sealing ring 1421 has a rebounding tendency, so that the abutting ring 1427 abuts against the mounting plate 24 in a sealing manner.

[0068] In the present embodiment, the design that the side of the first sealing ring 1421 away from the supporting ring 1412 is bent towards the connecting part 111 makes the elasticity of the first sealing ring 1421 better, the elastic force generated by the first sealing ring 1421 is greater when the first sealing ring 1421 elastically deforms, and the rebounding tendency of the first sealing ring 1421 is greater, so that the abutting ring 1427 is more closely attached to the mounting plate 24, and the sealing effect is better. In other embodiments, the abutting ring 1427 can be omitted, and the side of the first sealing ring 1421 away from the supporting ring 1412 abuts against the mounting plate 24 in a sealing manner.

[0069] In addition, by arranging the abutting ring 1427, the abutting ring 1427 abuts against the mounting plate 24, the surface of the abutting ring 1427 towards the mounting plate 24 can abut against the mounting plate 24, the abutting area of the abutting ring 1427 and the mounting plate 24 is greater, and thus the sealing effect is improved.

[0070] The above has introduced the embodiments of the present application in detail, and the principle and implementation mode of the present application have been described by applying specific examples. The above description of the embodiments is only used to help understand the method of the present application and its core idea.
