[0051] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application.

[0052] All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0053] As described in the background art, in the solutions of the related art, there is a risk that the charging piece on the lawn mower and the electrode piece on the charging pile are not connected in place, thus affecting normal charging. Through research, it is found that the reason for the above problem is that: in the related art, the charging piece on the lawn mower and the electrode piece on the charging pile are in point-to-point contact. When charging, if the electrode piece is inserted too deep or too shallow, it is easy to occur that the contact is not in place, thus affecting normal charging.

[0054] In view of this, the embodiments of the present application aim to provide an electrode piece, a first charging part, a second charging part, a charging assembly and a charging system. The electrode piece includes a charging section, the charging section is in a flat plate shape, and the charging section extends along the first direction. Along the first direction, the length of the charging piece is greater than the length of the contact piece. Along the second direction, the width of the charging piece is greater than the width of the contact piece. By setting the charging section of the electrode piece in a flat plate shape and extending a certain length along the first direction, and the width of the electrode piece in the second direction is greater than the width of the contact piece that cooperates with it, when charging, the electrode piece is inserted along the first direction to contact the contact piece. Compared with the point-to-point contact in the related art, the contact area between the electrode piece and the contact piece in the present application is larger, and there is a certain redundancy. Even if the electrode piece is not completely docked in place, it can ensure sufficient contact for charging.

[0055] The content of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can understand the content of the present application in more detail. It should be noted that in the description of this embodiment, the first direction X, the second direction Y, and the third direction Z are three different directions in a three-dimensional space. For example, the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other in pairs. The third direction Z can be, for example, the vertical direction, and the first direction X and the second direction Y can be, for example, two mutually perpendicular directions in the horizontal plane.

[0056] Please refer to Figure 1 , this embodiment provides an electrode sheet 110 for contacting the contact piece of the charging sheet to charge. The electrode sheet 110 can be made of a metal with good conductivity, such as a copper sheet, a silver sheet, etc. The electrode sheet 110 includes a charging section 111. The charging section 111 is in a flat plate shape and extends along the first direction X so that it has a certain length in the first direction X. It can be understood that the first direction X in this embodiment can be the insertion direction of the electrode sheet 110 during charging. Along the first direction X, the length of the charging section 111 is greater than the length of the contact piece, and along the second direction Y, the width of the charging section 111 is greater than the width of the contact piece, so as to ensure that the electrode sheet 110 of this embodiment has a larger charging area.

[0057] When charging with the electrode sheet 110 of this embodiment, the electrode sheet 110 is inserted along the first direction X and contacts the contact piece. Compared with the point-to-point contact in the related art, the contact area between the electrode sheet 110 and the contact piece in this embodiment is larger and has a certain redundancy, so that even if the electrode sheet 110 is not fully docked in place, sufficient contact charging can be ensured.

[0058] Furthermore, the electrode sheet 110 of this embodiment further includes a guiding section 112. The guiding section 112 is connected to the charging section 111, and the guiding section 112 is located on the side of the charging section 111 facing the contact piece (that is, the side in the insertion direction of the electrode sheet 110 during charging). In the direction away from the charging section 111, along the second direction Y, the width of the guiding section 112 gradually decreases.

[0059] By providing the guiding section 112 in this embodiment, the electrode sheet 110 can be guided to cooperate with the contact piece smoothly, ensuring the smooth progress of charging.

[0060] The electrode sheet 110 of this embodiment further includes a fixing section 113. The fixing section 113 is located on one side of the charging section 111 along the second direction Y. The fixing section 113 is used to connect other parts to fix the electrode sheet 110.

[0061] Exemplarily, the electrode sheet 110 of this embodiment further includes an electrode sheet connection section 114. The electrode sheet connection section 114 is connected to the fixed section 113 and is located on the side of the charging section 111 facing away from the guiding section 112 in the first direction X. The electrode sheet connection section 114 is used to connect to an external power source. For example, through holes may be provided on the electrode sheet connection section 114, and the charging wire led out from the external power source can be fixed in these through holes, thereby realizing electrical connection with the electrode sheet connection section 114.

[0062] Optionally, the charging section 111, the guiding section 112, the fixed section 113, and the electrode sheet connection section 114 of this embodiment are all located in the same plane. Through the above arrangement, compared with the bent electrode sheet in the prior art, the size and resistance of the electrode sheet 110 in this embodiment can be reduced.

[0063] Please refer to Figure 2 , this embodiment further provides a first charging part 100 for being installed on a first device; exemplarily, the first device 10 may be, for example, a charging pile. The first charging part 100 is used to cooperate with a second charging part for charging; that is to say, the first charging part 100 can be used to charge the second charging part. The first charging part 100 includes a first housing 120. Two of the above-mentioned electrode sheets 110 are arranged at intervals along the second direction Y inside the first housing 120. One of the two electrode sheets 110 is connected to the positive charging wire inside the first device, and the other is connected to the negative charging wire inside the first device. The charging sections 111 of the two electrode sheets 110 are respectively located on both sides of the first housing 120 along the second direction Y.

[0064] When the first charging part 100 is charging, it can simultaneously contact the contacts inside the second charging part through the charging sections 111 on both sides for charging. Due to the adoption of the above-mentioned electrode sheet 110, the contact area between the first charging part 100 and the contact piece in this embodiment is larger and has a certain redundancy. Even if the electrode sheet 110 is not fully docked in place, it can still ensure sufficient contact for charging.

[0065] Furthermore, in this embodiment, the electrode sheet 110 is passed through the first housing 120. It can be understood that a part of the electrode sheet 110 is located inside the first housing 120, thereby realizing connection and fixation with the first housing 120; another part is located outside the first housing 120 for charging.

[0066] Please continue to refer to Figure 1 and Figure 2, Specifically, the electrode sheet in this embodiment is connected to the first housing 120 through the fixing section 113. The first housing 120 in this embodiment includes a base 121 and a top cover 122. The base 121 is provided with positioning posts 1211, and the electrode sheet 110 is provided with positioning holes 1131. The positioning holes 1131 are sleeved on the positioning posts 1211 for installation and positioning. The base 121 and the top cover 122 are detachably connected, and the electrode sheet 110 can be clamped and fixed after the base 121 and the top cover 122 are connected. In this embodiment, the base 121 and the top cover 122 can be detachably connected by structures such as screws or snaps.

[0067] Please refer to Figure 3 and Figure 4 , This embodiment also provides a second charging part 200 for being installed on a second device. Exemplarily, the second device can be a device to be charged, such as a lawn mower, a vehicle, etc. The second charging part 200 is used to cooperate with the above-mentioned first charging part 100 to charge the second device. The second charging part 200 includes two charging sheets 210 arranged at intervals along the second direction Y. The charging sheet 210 includes a first clamping sheet 211 and a second clamping sheet 212 opposite to each other along the third direction Z. The first clamping sheet 211 and the second clamping sheet 212 are used to contact the electrode sheet 110 of the first charging part 100 for charging.

[0068] In this embodiment, by setting the charging sheet 210 as the first clamping sheet 211 and the second clamping sheet 212 opposite to each other along the third direction Z, when charging, the electrode sheet 110 is inserted between the first clamping sheet 211 and the second clamping sheet 212, and the two surfaces of the electrode sheet 110 are respectively in contact with the first clamping sheet 211 and the second clamping sheet 212, thereby increasing the contact area, which is beneficial to improving the charging speed and enhancing the user experience.

[0069] Please continue to refer to Figure 4 , In this embodiment, both the first clamping sheet 211 and the second clamping sheet 212 are elastic sheets, and the first clamping sheet 211 abuts against the second clamping sheet 212. When the electrode sheet 110 is inserted along the first direction X, the first clamping sheet 211 and the second clamping sheet 212 can be pushed open, and the first clamping sheet 211 and the second clamping sheet 212 clamp and fix the electrode sheet 110 under the action of their own elastic forces, so as to be in contact with the two surfaces of the electrode sheet 110 respectively and prevent the electrode sheet 110 from detaching.

[0070] In a possible implementation manner, the first clamping sheet 211 of this embodiment includes a first contact piece 2113, and the second clamping sheet 212 includes a second contact piece 2123. The charging sheet 210 further includes a pressing part, and the pressing part is connected to the first contact piece 2113 and / or the second contact piece 2123. The pressing part is used to press the first contact piece 2113 and / or the second contact piece 2123 so that the first contact piece 2113 contacts the second contact piece 2123.

[0071] In this embodiment, the extrusion part is provided to maintain the abutting state of the first contact piece 2113 and the second contact piece 2123, thereby preventing the electrode piece 110 from detaching and ensuring the normal progress of charging.

[0072] Specifically, the extrusion part of this embodiment includes a first elastic arm 2111, a first connecting section 2112, a second elastic arm 2121, and a second connecting section 2122.

[0073] Along the third direction Z, the first elastic arm 2111 and the second elastic arm 2121 are oppositely arranged. The first connecting section 2112 connects the first elastic arm 2111 and the first contact piece 2113 and is bent toward the second elastic arm 2121. The second contact piece 2123 connects the second elastic arm 2121 and the second contact piece 2123 and is bent toward the first elastic arm 2111. Both the first contact piece 2113 and the second contact piece 2123 are arranged substantially parallel to the plane formed by the first direction X and the second direction Y, and the first contact piece 2113 abuts against the second contact piece 2123.

[0074] In this embodiment, the sizes of the first contact piece 2113 and the second contact piece 2123 can be set as needed, so as to ensure that the electrode piece 110 has a sufficiently large contact area with the first contact piece 2113 and the second contact piece 2123 to ensure the charging speed.

[0075] Please continue to refer to Figure 3 , the second charging part 200 of this embodiment further includes a second housing 220. An installation groove 221 is formed in the second housing 220. Both charging pieces 210 are arranged in the installation groove 221. The installation groove 221 abuts against the first clamping piece 211 and the second clamping piece 212, so that the first clamping piece 211 and the second clamping piece 212 maintain an abutting state. That is to say, the first clamping piece 211 and the second clamping piece 212 of this embodiment can be abutted by the limitation of the installation groove 221. Therefore, as long as it is ensured that the charging piece 210 does not fall off from the installation groove 221, both the first clamping piece 211 and the second clamping piece 212 can maintain an abutting state.

[0076] Please continue to refer to Figure 4, the charging sheet 210 of this embodiment further includes a connecting section 213, a clip fixing section 214 and a charging line welding section 215. Among them, the two ends of the connecting section 213 are respectively connected to the first clip 211 and the second clip 212 to connect the first clip 211 and the second clip 212 as a whole. The clip fixing section 214 is arranged on one side of the connecting section 213 along the third direction Z, and the clip fixing section 214 is used to be fixedly connected with the mounting groove 221. Exemplarily, in this embodiment, a through hole can be provided on the clip fixing section 214, and a fixing hole can be provided in the mounting groove 221, and the first fastener 230 is passed through the through hole and fixed in the fixing hole, so that the clip fixing section 214 is fixedly connected with the mounting groove 221; the first fastener 230 can be, for example, a screw or a rivet. The charging line welding section 215 is arranged at one end of the clip fixing section 214 away from the connecting section 213, and the charging line welding section 215 is used to connect the battery in the second device 20. For example, the charging cable welding section 215 may be provided with a through hole, and the battery may be fixed in the through hole via a wire, thereby achieving electrical connection with the charging cable welding section 215 .

[0077] Please refer to Figure 5 and Figure 6 , this embodiment provides a charging component, including:

[0078] The first charging unit 100 is used to be installed on the first device 10; illustratively, the first device 10 may be a charging pile. The first charging unit 100 includes two electrode sheets 110 spaced apart along the second direction Y, one of the two electrode sheets 110 is connected to the positive charging line in the first device 10, and the other is connected to the negative charging line in the first device 10.

[0079] The second charging unit 200 is used to be installed on the second device 20; illustratively, the second device 20 can be, for example, a device to be charged, such as a lawn mower, a vehicle, etc. The second charging unit 200 includes two charging sheets 210 arranged at intervals along the second direction Y, one of the two charging sheets 210 is connected to the positive electrode of the battery in the second device 20, and the other is connected to the negative electrode of the battery in the second device 20. Each charging sheet 210 includes a first clip 211 and a second clip 212 that are opposite to each other along the third direction Z. The first clip 211 and the second clip 212 can be abutted; or, a gap can be formed between the first clip 211 and the second clip 212, and the gap is smaller than the thickness of the electrode sheet 110, so that the electrode sheet 110 can contact the first clip 211 and the second clip 212 at the same time.

[0080] In this embodiment, the two electrode plates 110 correspond to the two charging plates 210 one by one. The electrode plate 110 can be inserted between the corresponding first clamping piece 211 and the second clamping piece 212 along the third direction Z, and the two surfaces of the electrode plate 110 along the third direction Z are respectively abutted against the first clamping piece 211 and the second clamping piece 212 for charging.

[0081] In this embodiment, by setting the charging plate 210 as the first clamping piece 211 and the second clamping piece 212 opposite to each other along the third direction Z, when charging, the electrode plate 110 is inserted between the first clamping piece 211 and the second clamping piece 212 and the two surfaces of the electrode plate 110 are respectively in contact with the first clamping piece 211 and the second clamping piece 212, thereby increasing the contact area, which is beneficial to improving the charging speed and enhancing the user experience.

[0082] The specific structures of the first charging part 100 and the second charging part 200 in this embodiment have been described in detail above, and will not be elaborated herein.

[0083] Please continue to refer to Figures 7 - 12 , this embodiment also provides a charging system, including a first device 10, a second device 20 and the above-mentioned charging assembly. Among them, the first charging part 100 is installed on the first device 10, and the second charging part 200 is installed on the second device 20. The first device 10 can be, for example, a charging pile, and the second device 20 can be, for example, a lawn mower.

[0084] Since the charging system of this embodiment adopts the above-mentioned charging assembly, the contact area during charging between the first device 10 and the second device 20 is increased, which is beneficial to improving the charging speed of the second device 20.

[0092] Optionally, the cross-section of the rotating shaft groove 11 can be semi-circular. Two fixing members 13 are further provided in the first device 10. The fixing members 13 are provided with semi-grooves 131, and the cross-section of the semi-grooves 131 is also semi-circular and is adapted to the rotating shaft groove 11. The rotating shafts 130 can be fixed to the housing of the first device 10 by using the fixing members 13. Through holes can be provided at both ends of the fixing members 13, and corresponding fixing holes are provided on the housing of the first device 10. The second fastening member 14 passes through the through holes and is fixed in the corresponding fixing holes, so as to fix the fixing members 13 to the housing of the first device 10 and clamp the rotating shafts 130 between the fixing members 13 and the rotating shaft grooves 11.

[0093] Furthermore, a torsion spring 12 is further provided in the first device 10 of this embodiment. The torsion spring 12 is sleeved on the rotating shaft 130, and both ends of the torsion spring 12 are fixedly connected to the first device 10. By providing the torsion spring 12, the first charging part 100 can be restored to its initial state under the action of the torsion spring 12 after rotating relative to the first device 10, so as to facilitate subsequent charging use.

[0094] Exemplarily, the first device 10 of this embodiment may further include an avoidance member 15. The avoidance member 15 is disposed adjacent to the first charging portion 100. An avoidance space is formed on a portion of the avoidance member 15 that is exposed outside the housing of the first device 10. When the first charging portion 100 rotates relative to the first device 10, it can be located within the avoidance space. A torsion spring fixing groove 151 may be provided on the avoidance member 15. One end of the torsion spring 12 may be fixed in the torsion spring fixing groove 151, and the other end of the torsion spring 12 may be fixed to the housing of the first device 10.
