Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0034] An embodiment of the present application provides an electrical connection assembly, which is used for electrical connection between two electrical components. In one example, the electrical connection assembly is used for electrical connection between a power supply in a drone and a drone body. In the related art, as the electrical load of agricultural and transport drones increases, the power supply voltage of the drone is generally maintained below a specific value for safety reasons. In order to obtain higher power output, the power supply current must be increased. This places higher requirements on the electrical connection assembly between the power supply and the drone body, and the electrical connection assembly needs to be able to maintain a low contact resistance to achieve a higher overcurrent capability. In the related art, due to the frequent replacement of the power supply in the drone, there will be frequent plug-in and unplug operations between the male electrode and the female electrode of the electrical connection assembly, and the frequent plug-in and unplug operations will cause scratches on the surface where the male electrode and the female electrode contact each other, resulting in an increase in the contact resistance after the male electrode and the female electrode are electrically connected.

[0035] Figure 1 This is a three-dimensional schematic diagram of the first embodiment of the electrical connector assembly of the drone power supply of the present application in a connected state. Figure 2 , Figure 3 The three-dimensional schematic diagram and the front view schematic diagram of the first embodiment of the electrical connector assembly of the drone power supply of the present application in the disconnected state are respectively shown. The electrical connection assembly of the drone power supply includes a male electrode 100 and a female electrode 200. One end surface of the female electrode 200 has a clamping groove 211 that is recessed inward. The male electrode 100 can be inserted and clamped in the clamping groove 211, so that the male electrode 100 is electrically connected to the female electrode 200.

[0036] In this embodiment, at least one of the male electrode 100 and the female electrode 200 is provided with a lubricating block 300. The lubricating block 300 is a solid lubricant formed into a preset shape. When the male electrode 100 is inserted into the clamping groove 211, at least one of the female electrode 200 and the male electrode 100 is in frictional contact with the lubricating block 300.

[0037] According to the electrical connection assembly of the drone power supply of the embodiment of the present application, it includes a male electrode 100 and a female electrode 200, and the female electrode 200 has a clamping groove 211. At least one of the male electrode 100 and the female electrode 200 is provided with a lubricating block 300, and the lubricating block 300 is a solid lubricant formed into a preset shape. During the process of inserting the male electrode 100 into the clamping groove 211, at least one of the female electrode 200 and the male electrode 100 is in friction contact with the lubricating block 300, so that the lubricating block 300 is rubbed to generate lubricant powder located between the female electrode 200 and the male electrode 100. Therefore, when the male electrode 100 and the female electrode 200 are plugged in and out of each other, the lubricating powder generated by the lubricating block 300 provides surface lubrication, thereby reducing the possibility of scratches on the male electrode 100 and the female electrode 200, thereby reducing the possibility of increased contact resistance due to scratches, and ensuring that the electrical connection assembly has stable electrical connection performance. One of the male electrode 100 and the female electrode 200 is electrically connected to the drone body, and the other is electrically connected to the power supply, so that the electrical connection between the power supply and the drone body is achieved through the electrical connection component, thereby achieving the reliability of the electrical connection when the power supply is replaced.

[0038] The lubricating block 300 may be formed by a common solid powder molding scheme, for example, by mixing solid lubricant powder with a binder and then pressing the mixture into a molded structure, and attaching or installing the molded structure to at least one of the male electrode 100 and the female electrode 200 .

[0039] In some embodiments, the solid lubricant is graphite, molybdenum disulfide, hexagonal boron nitride, or polytetrafluoroethylene. Preferably, the solid lubricant is a conductor. For example, the solid lubricant is a conductive solid lubricant such as graphite and molybdenum disulfide. In this embodiment, the solid lubricant is graphite as an example for illustration. When the solid lubricant is a conductor, the lubricant powder generated by the friction of the lubricating block 300 is a conductive powder. The conductive powder not only provides lubrication when the male electrode 100 and the female electrode 200 are plugged in and out of each other, but also can fill the tiny gap in the contact surface between the male electrode 100 and the female electrode 200 after the male electrode 100 is inserted into the clamping groove 211, thereby further reducing the contact resistance after the male electrode 100 and the female electrode 200 are electrically connected, providing a guarantee for the passage of large current here.

[0040] In some embodiments, the male electrode 100 includes an electrode sheet 110 and a first lubricating block 310. The electrode sheet 110 includes an inserting portion 111 for inserting into the clamping groove 211. The first lubricating block 310 is disposed on at least a portion of the outer surface of the electrode sheet 110, and the female electrode 200 is in frictional contact with the first lubricating block 310 during the insertion of the male electrode 100 into the clamping groove 211.

[0041] In the above embodiment, the male electrode 100 is provided with a first lubricating block 310. When the male electrode 100 is inserted into the clamping groove 211, the female electrode 200 is in frictional contact with the first lubricating block 310. The first lubricating block 310 is rubbed to produce lubricant powder located between the female electrode 200 and the male electrode 100, thereby providing surface lubrication for the mutual plugging and unplugging process of the male electrode 100 and the female electrode 200.

[0042] Figure 4 This is a three-dimensional schematic diagram of the electrode sheet in the first embodiment of the electrical connector assembly of the drone power supply of the present application. In some embodiments, the insertion portion 111 includes a main body 111a and a support portion 111b located at one end of the main body 111a, and the first lubricating block 310 is fixedly disposed on the support portion 111b. When the male electrode 100 is inserted into the clamping groove 211, the female electrode 200 first contacts the first lubricating block 310 and then contacts the main body 111a.

[0043] In the above embodiment, when the male electrode 100 is inserted into the clamping groove 211, the female electrode 200 first contacts the first lubricating block 310. At this time, the first lubricating block 310 is rubbed to generate lubricant powder which adheres to the surface of the female electrode 200. As the male electrode 100 continues to be inserted, the female electrode 200 contacts the main body 111a. At this time, the lubricant powder can provide lubrication between the female electrode 200 and the main body 111a, thereby reducing the possibility of scratches on the surface of the main body 111a and / or the female electrode 200.

[0044] In some embodiments, the first lubricating block 310 covers the two opposite surfaces of the support portion 111b and the end surface of the support portion 111b away from the main body 111a. After the male electrode 100 is inserted into the clamping groove 211, the female electrode 200 clamps the two opposite surfaces of the support portion 111b and the main body 111a. Since the first lubricating block 310 covers the two opposite surfaces of the support portion 111b and the end surface of the support portion 111b away from the main body 111a, when the male electrode 100 is inserted into the clamping groove 211, the lubricant powder generated by the first lubricating block 310 adheres to the two inner side surfaces of the female electrode 200 for clamping the male electrode 100, ensuring that the lubricant powder can exist between the two opposite surfaces of the main body 111a and the female electrode 200.

[0045] In some embodiments, the support portion 111b has a plurality of through holes H1 disposed through two opposite surfaces thereof, and the first lubricating block 310 fills the plurality of through holes H1. By disposing a plurality of through holes H1 on the support portion 111b, it is convenient to form the lubricating block 300 at the support portion 111b, and the lubricating block 300 is more firmly attached to the support portion 111b after forming, thereby reducing the possibility of the lubricating block 300 falling off from the support portion 111b as a whole.

[0046] In some embodiments, the end surface of the first lubricating block 310 away from the main body 111 a is provided with a chamfered structure or a rounded structure, so as to further improve the smoothness of the process of inserting the male electrode 100 into the clamping groove 211 .

[0047] In some embodiments, the female electrode 200 includes a clamping seat 210 and a pair of springs 220. The clamping groove 211 is provided in the clamping seat 210. The pair of springs 220 are respectively provided on two opposite side walls in the clamping groove 211, and the pair of springs 220 can elastically clamp the insertion portion 111 inserted in the clamping groove 211. When the male electrode 100 is inserted into the clamping groove 211, the pair of springs 220 is in frictional contact with the first lubricating block 310.

[0048] In the above embodiment, during the process of inserting the male electrode 100 into the clamping groove 211, the pair of spring pieces 220 firstly come into frictional contact with the first lubricating block 310, so that lubricant powder is attached to the surface of the spring pieces 220. Afterwards, as the male electrode 100 continues to be inserted, the pair of spring pieces 220 clamps the main body 111a, and at this time, the lubricant powder can provide lubrication between the spring pieces 220 and the main body 111a.

[0049] In some embodiments, the electrode sheet 110 of the male electrode 100 further includes a first electrical connection portion 112, the first electrical connection portion 112 is connected to the insertion portion 111, and the first electrical connection portion 112 is used to connect to the first wire. In this embodiment, the insertion portion 111 of the electrode sheet 110 includes a main body portion 111a and a support portion 111b located at one end of the main body portion 111a, and the support portion 111b and the first electrical connection portion 112 are located at opposite ends of the main body portion 111a.

[0050] In some embodiments, the female electrode 200 further includes a second electrical connection portion 230, which is connected to the clamping seat 210 and is used to connect to the second wire. In this embodiment, the second electrical connection portion 230 is located on a side of the clamping seat 210 away from the notch of the clamping slot 211.

[0051] Figure 5 , Figure 6 , Figure 7 They are respectively a three-dimensional schematic diagram, a side view schematic diagram, and a cross-sectional schematic diagram of the second embodiment of the electrical connector assembly of the drone power supply of the present application in a connected state, wherein: Figure 6 The AA line shows Figure 7The cut-off position of the cross-sectional schematic diagram. The electrical connection assembly includes a male electrode 100 and a female electrode 200. One end surface of the female electrode 200 has a clamping groove 211 that is recessed inward. The male electrode 100 can be inserted into and clamped in the clamping groove 211, so that the male electrode 100 is electrically connected to the female electrode 200. At least one of the male electrode 100 and the female electrode 200 is provided with a lubricating block 300, which is a solid lubricant formed into a preset shape. During the process of inserting the male electrode 100 into the clamping groove 211, at least one of the female electrode 200 and the male electrode 100 is in frictional contact with the lubricating block 300.

[0052] In the second embodiment, the female electrode 200 includes a clamping seat 210, a pair of spring sheets 220, and a second lubricating block 320. The clamping slot 211 is provided in the clamping seat 210. The pair of spring sheets 220 are respectively provided on two opposite side walls in the clamping slot 211, and the pair of spring sheets 220 can elastically clamp the male electrode 100 inserted in the clamping slot 211. The second lubricating block 320 is provided on at least one side wall in the clamping slot 211. When the male electrode 100 is inserted into the clamping slot 211, the male electrode 100 is in frictional contact with the second lubricating block 320.

[0053] In the above embodiment, the female electrode 200 is provided with a second lubricating block 320. During the process of inserting the male electrode 100 into the clamping groove 211, the male electrode 100 is in frictional contact with the second lubricating block 320. The second lubricating block 320 is rubbed to produce lubricant powder located between the spring piece 220 and the male electrode 100, thereby providing surface lubrication for the mutual plugging and unplugging process of the male electrode 100 and the female electrode 200.

[0054] In this embodiment, the second lubricating block 320 is located on a side of the spring sheet 220 close to the notch of the clamping groove 211. When the male electrode 100 is inserted into the clamping groove 211, the male electrode 100 first contacts the second lubricating block 320. At this time, the second lubricating block 320 is rubbed to generate lubricant powder, which is attached to the surface of the male electrode 100. As the male electrode 100 continues to be inserted, the male electrode 100 contacts the spring sheet 220. At this time, the lubricant powder can provide lubrication between the male electrode 100 and the spring sheet 220, thereby reducing the possibility of scratches on the surface of the male electrode 100 and / or the spring sheet 220.

[0055] In this embodiment, the second lubricating blocks 320 are arranged in pairs, and the paired second lubricating blocks 320 are respectively arranged on two opposite side walls in the clamping groove 211. In this embodiment, the female electrode 200 further includes an elastic member 240. The elastic member 240 is connected to at least one of the second lubricating blocks 320, and the elastic member 240 can reset the paired second lubricating blocks 320 in a direction close to each other.

[0056] In this embodiment, each second lubricating block 320 is connected to the corresponding side wall of the clamping groove 211 through a corresponding elastic member 240. In some other embodiments, the elastic member 240 can be connected in other ways, such as connecting to two second lubricating blocks 320 in a pair through a single elastic member 240 at the same time, as long as the second lubricating blocks 320 in a pair can be reset in a direction close to each other. Since the elastic member 240 can reset the second lubricating blocks 320 in a pair to be close to each other, when the male electrode 100 is inserted into the clamping groove 211, the male electrode 100 can be clamped and rubbed by the second lubricating blocks 320 in a pair when passing through the second lubricating blocks 320, thereby ensuring that sufficient lubricant powder can be attached to the surface of the male electrode 100 to ensure the lubrication effect.

[0057] In some optional embodiments, the male electrode 100 may include an electrode sheet 110 and a first lubricating block 310, and the female electrode 200 includes a second lubricating block 320. The structure of the male electrode 100 is similar to that of the above-mentioned first embodiment, and the structure of the female electrode 200 is similar to that of the above-mentioned second embodiment, so that the electrical connection component forms multiple lubrications during plugging and unplugging.

[0058] The embodiment of the present application also provides a drone, which includes a drone body, a power source, and an electrical connection component of the drone power source of any of the above-mentioned embodiments. The power source is provided on the drone body, and the power source is used to power the drone. The power source is, for example, a battery. The electrical connection component includes a male electrode 100 and a female electrode 200. One end surface of the female electrode 200 has a clamping groove 211 that is recessed inward. The male electrode 100 can be inserted and clamped in the clamping groove 211, so that the male electrode 100 is electrically connected to the female electrode 200. At least one of the male electrode 100 and the female electrode 200 is provided with a lubricating block 300, which is a solid lubricant formed into a preset shape. During the process of inserting the male electrode 100 into the clamping groove 211, at least one of the female electrode 200 and the male electrode 100 is in frictional contact with the lubricating block 300. One of the male electrode 100 and the female electrode 200 is electrically connected to the drone body, and the other is electrically connected to the power source.
