[0038] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present utility model.
[0042] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.
[0043] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.
[0044] As mentioned in the background technology, the battery connection end and the fuselage connection end of the plant protection drone need to be in contact through electrode sheets to achieve the conductive process, but the working environment of the plant protection drone is harsh (accompanied by vibration), and it is difficult to ensure that the electrode sheets are always in stable contact, which affects the use of the plant protection drone.
[0045] At the same time, the current between the battery connection terminal and the fuselage connection terminal is very large, about 200A-500A, requiring a large current capacity, and the number of docking times between the battery connection terminal and the fuselage connection terminal is also required to be high, generally at least 3000 times or more.
[0046] Existing electrical connectors (including battery connection terminals and body connection terminals) are difficult to meet the above requirements.
[0047] In addition, the resistance between the battery connection terminal and the body connection terminal is large, the high temperature affects the life of the electrode sheet, and the current flow capacity between the battery connection terminal and the body connection terminal is poor.
[0048] In view of this, please refer to Figure 1-Figure 7 The electrode spring, electrode structure, electrical connector and agricultural unmanned equipment provided in the embodiments of the utility model can solve this problem, which will be described in detail below.
[0049] An agricultural unmanned equipment is provided in an embodiment of the utility model. The agricultural unmanned equipment may be an unmanned vehicle, a plant protection drone, etc., and may be applied to agricultural scenes. In the field of plant protection, various operating equipment may be installed on the agricultural unmanned equipment to realize operations such as spraying pesticides, sowing seeds, and powders.
[0050] Among them, the unmanned vehicle can travel on land and can be used in the agricultural industry for plant protection operations such as spraying pesticides or watering crops.
[0051] The plant protection drone can be used in agricultural plant protection operations to spray crops, and can spray liquids such as pesticides and water.
[0052] In this embodiment, the agricultural unmanned equipment can be understood as a plant protection drone, and the agricultural unmanned equipment includes an electrical connector, which can ensure the normal conduction process between the battery connection end and the fuselage connection end.
[0053] Specifically, the electrical connector includes a first connection end, a second connection end and an electrode structure, and the first connection end and / or the second connection end is provided with an electrode structure, wherein the first connection end can be understood as a battery connection end, and the second connection end can be understood as a body connection end.
[0054] Of course, in other embodiments, the second connection end may be understood as a battery connection end, and the first connection end may be understood as a body connection end.
[0055] In this embodiment, an electrode structure may be provided at the first connection end, while the electrode structure is not provided at the second connection end. The second connection end does not include the electrode structure but is provided with an electrode sheet 10 (a copper sheet may be selected).
[0056] Of course, in other embodiments, the second connection end may be provided with an electrode structure, while the first connection end is not provided with an electrode structure, or the first connection end does not include the electrode structure but is provided with an electrode sheet 10, such as a copper sheet.
[0057] Please refer to Figure 1-Figure 3 The electrode structure includes an electrode sheet 10 and an electrode spring sheet. The electrode sheet 10 and the electrode spring sheet are connected. The electrode sheet 10 and the electrode spring sheet can be connected by welding. The electrode sheet 10 can be arranged at the first connection end.
[0058] Among them, the electrode spring includes a floating elastic strip 200, a fixed elastic strip 300, and a first connecting member 110 and a second connecting member 120 distributed at intervals. The floating elastic strip 200 has a fixed end and a free end 210. The fixed end is fixedly connected to the first connecting member 110, and the free end 210 is spaced apart from the second connecting member 120. The two ends of the fixed elastic strip 300 are respectively fixedly connected to the first connecting member 110 and the second connecting member 120.
[0059] Among them, the floating elastic strip 200 and the fixed elastic strip 300 are located between the first connecting member 110 and the second connecting member 120, and the free end 210 of the floating elastic strip 200 of the electrode spring has a larger floating amplitude than the fixed elastic strip 300, so as to ensure that at least the floating elastic strip 200 can maintain contact with the electrode sheet 10 (for example, a copper sheet can be selected) located at the other connection end in the working environment of the plant protection drone (accompanied by vibration) to ensure the normal conduction process between the battery connection end and the fuselage connection end.
[0060] That is to say, the free end 210 of the floating elastic strip 200 can always be in contact with the electrode sheet 10 located on the second connection end, thereby ensuring a normal conduction process between the battery connection end and the body connection end.
[0061] It should be noted that, in this embodiment, the first connecting member 110 and the electrode sheet 10 are fixedly connected by welding, and the second connecting member 120 is used to be slidably connected to the electrode sheet 10, and the second connecting member 120 can always maintain contact with the electrode sheet 10 at the first connection end.
[0062] In this embodiment, the first connecting member 110 and the second connecting member 120 are both plate-shaped structures. Meanwhile, the first connecting member 110 and the second connecting member 120 are located in the same plane, and the first connecting member 110 and the second connecting member 120 are distributed in parallel.
[0063] It should be noted that the entire electrode spring piece can be made of a conductive metal material, and the entire electrode spring piece can be integrally formed by stamping.
[0064] In order to facilitate the floating elastic strip 200 and the fixed elastic strip 300 to contact and conduct electricity with the electrode sheet 10 located at the second connection end, in this embodiment, please refer to Figure 4 The floating elastic strip 200 and the fixed elastic strip 300 are in an arc-shaped structure, and the curvature of the floating elastic strip 200 is the same as the curvature of the fixed elastic strip 300.
[0065] Of course, in other embodiments, the floating elastic strip 200 may be in an arc-shaped structure, or the fixed elastic strip 300 may be in an arc-shaped structure.
[0066] It is easy to understand that in this embodiment, since the floating elastic strip 200 is an arc-shaped structure, the distance between the middle of the floating elastic strip 200 and the electrode sheet 10 located at the first connection end is greater than the distance between the end of the floating elastic strip 200 and the electrode sheet 10 located at the first connection end. In this way, when the floating elastic strip 200 and the fixed elastic strip 300 are contacted and pressed by the electrode sheet 10 located at the second connection end, the floating elastic strip 200 and the fixed elastic strip 300 can undergo a large elastic deformation, and the first connecting member 110 and the second connecting member 120 are respectively equivalent to two supports of the elastic electrode sheet, thereby increasing the number of docking times between the battery connection end and the body connection end, and improving the service life of the electrical connector.
[0067] Please refer to Figure 6 and Figure 7 , wherein the second connecting member 120 on the electrode sheet 10 at the first connecting end is at a certain distance from the right side of the electrode sheet 10 , so that the second connecting member 120 can slide on the electrode sheet 10 .
[0068] When the electrode sheet 10 at the second connection end contacts the electrode spring sheet at the first connection end, the floating elastic strip 200 and the fixed elastic strip 300 of the electrode spring sheet are deformed, and the second connecting member 120 slides to the right relative to the electrode sheet 10 at the first connection end. It is easy to understand that at this time, the first connecting member 110 and the second connecting member 120 both contact the electrode sheet 10 at the first connection end, thereby increasing the current capacity.
[0069] In addition, in order to improve the current flow capacity, in this embodiment, the number of floating elastic strips 200 and / or the number of fixed elastic strips 300 is multiple, multiple floating elastic strips 200 are distributed in sequence and / or multiple fixed elastic strips 300 are distributed in sequence and spaced apart, and adjacent floating elastic strips 200 and fixed elastic strips 300 are spaced apart. Multiple here can be understood as at least two.
[0070] Among them, please refer to Figure 5 Combined with Figure 1 The number of floating elastic strips 200 and the number of fixed elastic strips 300 can both be multiple, for example, the number of floating elastic strips 200 is four, and the number of fixed elastic strips 300 is five. In some embodiments, the number of floating elastic strips 200 can be one, and the number of fixed elastic strips 300 can be two. In some embodiments, the number of floating elastic strips 200 can be two, and the number of fixed elastic strips 300 can be one.
[0071] In addition, at least one floating elastic strip 200 is distributed between adjacent fixed elastic strips 300, the number of fixed elastic strips 300 is greater than the number of floating elastic strips 200, and the adjacent fixed elastic strips 300, the first connecting member 110 and the second connecting member 120 jointly surround a protective space, and at least one floating elastic strip 200 is distributed in the protective space. In the present embodiment, one floating elastic strip 200 is distributed in the protective space. In other embodiments, two floating elastic strips 200 may be distributed in the protective space.
[0072] It is easy to understand that the floating elastic strip 200 is set in the protective space, and the adjacent fixed elastic strip 300, the first connecting member 110 and the second connecting member 120 can protect the floating elastic strip 200 in the protective space to prevent the electrode spring piece from being damaged and deformed during the welding process or transportation process. At the same time, the fixed elastic strip 300 can also conduct electricity to improve the current carrying capacity.
[0073] In addition, it is easy to understand that since both ends of the fixed elastic strip 300 are fixedly connected to the first connecting member 110 and the second connecting member 120, when the electrode sheet 10 located at the second connecting end contacted by one of the fixed elastic strips 300 is deformed, the remaining fixed elastic strips 300 will also be deformed synchronously, which may easily lead to the remaining fixed elastic strips 300 being unable to closely contact the electrode sheet 10 located at the second connecting end. The floating elastic strip 200 has a free end 210, and the deformation process of each floating elastic strip 200 is independent, which can ensure that each floating elastic strip 200 is in contact with the electrode sheet 10 located at the second connecting end as much as possible, thereby improving the current carrying capacity of the electrode structure.
[0074] In some embodiments, both the first connection end and the second connection end may be provided with an electrode structure, and the conduction process is achieved by the electrode structure located at the first connection end contacting the electrode structure located at the second connection end. Specifically, the floating elastic strip 200 of one electrode structure may contact the floating elastic strip 200 of another electrode structure, and the fixed elastic strip 300 of one electrode structure may contact the fixed elastic strip 300 of another electrode structure.
[0075] To summarize, the electrode spring includes a floating elastic strip 200, a fixed elastic strip 300, and a first connecting member 110 and a second connecting member 120 that are spaced apart. The floating elastic strip 200 has a fixed end and a free end 210. The fixed end is fixedly connected to the first connecting member 110, and the free end 210 is spaced apart from the second connecting member 120. The two ends of the fixed elastic strip 300 are fixedly connected to the first connecting member 110 and the second connecting member 120, respectively.
[0076] Among them, the floating elastic strip 200 and the fixed elastic strip 300 are located between the first connecting member 110 and the second connecting member 120. The free end 210 of the floating elastic strip 200 of the electrode spring has a larger floating amplitude than the fixed elastic strip 300, so as to ensure that at least the floating elastic strip 200 can maintain contact with the electrode sheet 10 located at the other connection end in the working environment of the plant protection drone (accompanied by vibration) to ensure the normal conduction process between the battery connection end and the fuselage connection end.
[0077] The electrode structure includes an electrode sheet 10 and the electrode spring sheet mentioned above. The electrode sheet 10 and the electrode spring sheet are connected. The electrode structure has all the functions of the electrode spring sheet mentioned above.
[0078] Among them, the electrode structure can be understood as adding electrode springs to the existing electrode sheet 10 to reduce resistance, increase heat dissipation area, improve the life of the electrode structure, and improve the overcurrent capacity to meet the overcurrent requirements required by the battery connection terminal and the body connection terminal.
[0079] The electrical connector includes a first connection end, a second connection end and the above-mentioned electrode structure. The first connection end and / or the second connection end is provided with the electrode structure. The electrical connector has all the functions of the above-mentioned electrode structure. The electrical connector has a long service life and meets the requirement of at least 3,000 docking times between the battery connection end and the body connection end.
[0080] The agricultural unmanned equipment includes the above-mentioned electrical connector, and the agricultural unmanned equipment has all the functions of the above-mentioned electrical connector.
[0081] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
