Description

Technical Field

[0001] This application belongs to the field of mechanical equipment, and more specifically, relates to a charging component, a charging base station, and an operating device. Background Technology

[0002] With technological advancements, autonomous mobile cleaning equipment has become widely used. Examples include autonomous floor cleaning equipment (robot sweepers, robot mops, etc.) and intelligent lawnmowers. Taking intelligent lawnmowers as an example, an intelligent lawnmower is a device that can autonomously control its walking route and work area, performing tasks such as mowing and trimming the lawn within a designated area. To facilitate lawnmower operation, a matching charging station is typically installed. When the lawnmower's battery level drops below a set value, it can return to the charging station and recharge under program-driven operation.

[0003] The charging base station is equipped with charging contact plates, and the lawnmower also has corresponding charging contact plates. When the lawnmower's charging contact plate comes into contact with the charging base station's contact plate, the contact plate can output electrical energy to the charging contact plate to charge the lawnmower. However, in related technologies, the contact plates suffer from a low success rate in docking, and after a certain period of use, the contact plates may become unusable for charging due to plating wear and damage, severely affecting their performance.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0017] An elastic part is sleeved on the rotating shaft and is located at least between the first abutting arm and the second abutting arm;

[0018] In response to the deformation of the contact electrode, at least one of the first abutting arm and the second abutting arm causes the elastic part to deform and accumulate elastic potential energy.

[0019] In one feasible implementation, the contact electrode further includes a second connector, which is connected to the first charging contact or the end of the second charging contact facing away from the first connector.

[0022] In one feasible implementation, the first connector includes a first plate, an arc-shaped transition portion, and a second plate.

Most importantly, the first connector of the aforementioned contact electrode is an elastic structure. The first connector allows for recoverable elastic deformation during docking with the working equipment. Simultaneously, in conjunction with the elastic element, it helps reduce the friction between the contact electrode and the docking electrode, thereby improving the compressive force on the contact electrode during charging to a certain extent, increasing the service life of the contact electrode, and ultimately improving the performance of the charging component.

Therefore, the beneficial effects of the charging base station and operating device including at least one or more of the above-mentioned charging components will not be repeated here.

[0063] An embodiment of the present application provides a charging component 10, a charging base station 100, and a working device 1000. The charging component 10 is combined with a charging base 20 to form the charging base station 100, and the charging base station 100 cooperates with a working device 200 to form the working device 1000. The working device 1000 has the charging base station 100 with the charging component 10, and also has a working device 200 with a certain autonomous working function. The working device 200 can be a mowing device that can be charged through the charging base station 100 and can realize the autonomous mowing function. The mowing device can independently complete the lawn trimming work and can perform mowing operations according to the set path and time. It can be understood that a charging component, such as a charging pole piece 210, is provided on the working device 200. When the working device 200 travels to the charging base station 100 through an access passage 201, the charging component 10 located on the charging base station 100 can be electrically connected to the charging component on the working device 200 to implement the charging operation of the working device 200.

[0064] Taking the working device 200 as a lawn mower as an example, the lawn mower can be used for garden maintenance and can independently complete the lawn trimming work within a certain range. The charging base station 100 is used to charge the above-mentioned lawn mower. For example, when the lawn mower starts working, it can start from a set position and execute the mowing task; when the lawn mower completes the mowing task or needs to be charged, the lawn mower can travel to the charging base station 100 for charging. After the charging is completed, if the lawn mower is still within the set working time, the lawn mower can automatically return to the unfinished working area before for mowing operations.

[0065] Figure 1 It is a schematic structural diagram of the charging component 10 provided by an embodiment of the present application. Figure 2 It is a schematic structural diagram of the charging component 10 provided by another embodiment of the present application.

[0066] Please refer to Figure 1 and Figure 2 An embodiment of the present application provides a charging component 10, which can be used to be installed on the charging base station 100 for docking and charging with a working device 200 supporting the charging base station 100.

[0067] Specifically, the charging component 10 includes a contact pole piece 1, and the contact pole piece 1 can be installed at an installation position on the charging base station 100. The contact pole piece 1 at least includes a first connecting piece 11, a first charging contact piece 12, and a second charging contact piece 13. The first charging contact piece 12 and the second charging contact piece 13 are arranged at intervals, and both ends of the first connecting piece 11 in the length direction are respectively connected to the first charging contact piece 12 and the second charging contact piece 13.

[0068] Both the first charging contact 12 and the second charging contact 13 are used to contact the charging electrode 210 on the working device 200. Since the contact electrode 1 has two charging structures that can be used to achieve contact charging, when the working device 200 contacts the contact electrode 1, the first charging contact 12 and the second charging contact 13 connected by the first connector 11 can improve the success rate of docking between the charging component 10 and the working device 200. Furthermore, the above structure can effectively overcome the safety hazards caused by charging when the contact electrode 1 and the charging electrode 210 are not properly docked, thereby improving the safety of docking and charging between the contact electrode 1 and the working device 200.

[0069] Contact electrode 1 is a metal electrode.

[0070] Please see Figure 1 and Figure 2 The aforementioned contact electrode 1 includes a first connector 11, a first charging contact 12, and a second charging contact 13, wherein the first charging contact 12 and the second charging contact 13 are independent components spaced apart and maintaining a certain distance in space. The two ends of the first connector 11 in the length direction are respectively used to connect to the first charging contact 12 and the second charging contact 13 to form a relatively stable integrated structure. The first connector 11, the first charging contact 12, and the second charging contact 13 can be integrally formed, or they can be fixedly connected by welding or other methods to ensure a relatively stable positional relationship between the first charging contact 12 and the second charging contact 13. Of course, in this embodiment, the first connector 11, the first charging contact 12, and the second charging contact 13 are integrally formed. This structure makes the connection between the various components of the contact electrode 1 more stable, reducing the complexity of the structure and ultimately improving the overall integrity of the contact electrode 1 and the stability of the electrical components.

[0071] To ensure that the first charging contact 12 and the second charging contact 13 can smoothly connect with the charging electrode 210 on the working equipment 200, both the first charging contact 12 and the second charging contact 13 are provided with a charging contact area 101, which includes an arc-shaped structure that protrudes at least partially in the direction away from the first connector 11.

[0072] Please see Figure 1 and Figure 2The charging contact area 101 includes an arc-shaped structure that protrudes at least partially away from the first connector 11. This arc-shaped structure effectively improves the contact strength between the contact electrode 1 and the working device 200, and is a key component of the contact electrode 1. The arc-shaped structure of the charging contact area 101 increases the contact area and stability between the contact electrode 1 and the working device 200 during docking, thus improving the docking success rate. In addition, the arc-shaped structure gives the charging contact area 101 a certain degree of elasticity, allowing for appropriate deformation during contact. This helps compensate for potential positional deviations that may occur when the working device 200 docks with the contact electrode 1, further ensuring the stability and continuity of the charging process and allowing the current in the charging base station 100 to flow smoothly from the contact electrode 1 to the working device 200.

[0073] Specifically, the charging contact area 101 and the contact electrode 1 are integrally formed.

[0074] In some embodiments, the size of the charging contact area 101 along the length of the first connector 11 is not smaller than the size of the first connector 11. Furthermore, the charging contact area 101 is located on the same side of the first connector 11 to facilitate better docking with the operating device 200.

[0075] In other similar embodiments, the charging contact area 101 may also have a charging contact that protrudes outward relative to the charging contact area 101.

[0076] Specifically, there is at least one charging contact.

[0077] Please see Figure 1 and Figure 2 The contact electrode 1 also includes a second connector 14, which is integrally formed with the first charging contact 12, the first connector 11 and the second charging contact 13.

[0078] Specifically, the second connector 14 is connected to the end of the first charging contact 12 or the second charging contact 13 that faces away from the first connector 11. When there is only one second connector 14, it is connected to the end of the first charging contact 12 or the second charging contact 13 that faces away from the first connector 11. Please refer to [link to relevant documentation]. Figure 1 .

[0079] Specifically, the second connector 14 is connected to at least a portion of the surface of the first connector 11 on one side in the height direction. (See also...) Figure 2 The height direction of the first connector 11 is orthogonal to the length direction of the first connector 11.

[0080] The second connector 14 is used to enable circuit conduction.

[0081] Please see Figure 1 and Figure 2 The end of the second connector 14 is provided with a hole-like structure, and the power supply wire harness is provided with conductive metal protrusions or conductive wire harnesses that match the hole-like structure. After the wire harness is inserted into the hole-like structure, a fixed connection with the second connector 14 and circuit conduction can be achieved through the metal protrusions.

[0082] The first connector 11, which connects the first charging contact 12 and the second charging contact 13, can not only be used to realize the transmission of current between the two contacts, but also to improve the flexibility and elasticity of the contact electrode 1, so that it has better deformation recovery function.

[0083] Please see Figure 1 The first connector 11 includes a first plate 111, an arc-shaped transition portion 113, and a second plate 112. The first plate 111 and the second plate 112 are parallel to each other. The arc-shaped transition portion 113 connects the first plate 111 and the second plate 112. The connection between the arc-shaped transition portion 113 and either the first plate 111 or the second plate 112 is smooth.

[0084] The above-mentioned parallelism means that the first plate 111 and the second plate 112 are strictly parallel, and there is a constant distance between the first plate 111 and the second plate 112; or, it can also mean that the first plate 111 and the second plate 112 are approximately parallel or tend to be parallel, and the distance between the first plate 111 and the second plate 112 is not constant and there is a certain error, the above error not exceeding 20%.

[0085] Alternatively, please see Figure 2 The first connecting member 11 includes a first plate 111, an arc-shaped transition portion 113, and a second plate 112. The first plate 111 and the second plate 112 are perpendicular to each other. The arc-shaped transition portion 113 connects the first plate 111 and the second plate 112. The connection between the arc-shaped transition portion 113 and either the first plate 111 or the second plate 112 is smooth.

[0086] The above-mentioned perpendicularity means that the included angle between the first plate 111 and the second plate 112 is a right angle, in which case the first plate 111 and the second plate 112 remain perpendicular; or, it can also mean that the included angle between the first plate 111 and the second plate 112 is approximately a right angle, in which case the included angle between the first plate 111 and the second plate 112 can be 75° to 105°.

[0087] The first connector 11 can connect the first charging contact 12 and the second charging contact 13 to the first plate 111 and the second plate 112 respectively. The arc-shaped transition portion 113 improves the deformation recovery capability and elasticity of the contact electrode 1. When at least one of the first charging contact 12 and the second charging contact 13 is subjected to external pressure, the arc-shaped transition portion 113 can undergo a certain degree of bending deformation under the action of external force, and absorb and disperse the external force through deformation, thereby providing a larger elastic deformation space for the contact electrode 1. When the external force is withdrawn, the arc-shaped transition portion 113 can quickly return to its original shape.

[0088] The arc-shaped transition portion 113 allows the contact electrode 1 to maintain a stable shape and performance during multiple charging and docking processes, extending its service life and further improving the reliability of the contact electrode 1 when docking with the charging electrode 210 of the working equipment 200. In addition, the arc-shaped transition portion 113 also has a certain buffering and shock absorption function, which can buffer the impact force when the working equipment 200 contacts the contact electrode 1, and also reduce the risk of poor charging contact caused by impact.

[0089] Figure 3 This is a schematic diagram of the structure of the charging component 10 provided in another embodiment of this application. Figure 4 for Figure 3 Explosion diagram, Figure 5 for Figure 3 Enlarged view of the structure of region A in the middle. Figure 6 for Figure 3 Enlarged view of the structure of region B in the middle. Figure 7 for Figure 3 A schematic diagram of the structure of the limiting part 22 in the middle. Figure 8 for Figure 3 A schematic diagram of the assembly of the contact electrode 1, the limiting part 22 and the elastic element 3.

[0090] Please see Figure 3 In addition to the contact electrode 1, the charging component 10 also includes a mounting bracket 2. The mounting bracket 2 is positioned toward the access channel 201 of the charging base station 100 to provide mounting support for the contact electrode 1.

[0091] The contact electrode 1 mounted on the mounting bracket 2 is positioned facing the access channel 201. When the working equipment 200 enters or exits relative to the charging base station 100 through the access channel 201, it can dock with or detach from the contact electrode 1 mounted on the mounting bracket 2.

[0092] Specifically, the number of contact electrodes 1 is at least two, and they are symmetrically arranged on both sides of the inlet / outlet channel 201. Please refer to [link / reference]. Figure 3 In the figure, there are two contact electrodes 1, which are located on both sides of the inlet / outlet channel 201. At this time, the contact electrodes 1 are in a state where they can easily come into contact with the working equipment 200.

[0093] The contact electrode 1 located on one side of the access channel 201 can serve as the positive charging electrode, and the contact electrode 1 on the other side can serve as the negative charging electrode. In addition, the two oppositely arranged contact electrodes 1 can be located at the same position in the height direction of the mounting bracket 2.

[0094] The charging component 10 also includes an elastic element 3, with the contact electrode 1 and the mounting bracket 2 respectively connected to the elastic element 3. When an external force is applied to the contact electrode 1 and causes it to deform, the elastic element 3 accumulates elastic potential energy in response to the deformation of the contact electrode 1.

[0095] The elastic potential energy stored in the elastic element 3 acts on the contact electrode 1 after the external force is removed, causing the contact electrode 1 to recover its deformation. For example, when the working device 200 docks with the contact electrode 1, the working device 200 first contacts the contact electrode 1. The contact electrode 1 deforms under the compression of the external force provided by the working device 200 and further transmits the external force to the elastic element 3 through deformation, causing the elastic element 3 to deform under force. During this process, the elastic element 3 stores elastic potential energy. When the working device 200 separates from the contact electrode 1, as the working device 200 moves away, the external force acting on the contact electrode 1 disappears. At this time, the elastic potential energy stored in the elastic element 3 begins to be released and gradually recovers to the initial state. In response to the elastic reset of the elastic element 3, the contact electrode 1 recovers its initial shape.

[0096] Please see Figure 4 , Figure 5 and Figure 6 The elastic element 3 can be a torsion spring structure, which can include a connected abutment arm and an elastic part 33. The abutment arm includes a first abutment arm 31 for abutting against the contact electrode 1 and a second abutment arm 32 for abutting against the limiting part 22. The elastic part 33 is located between the first abutment arm 31 and the second abutment arm 32.

[0097] In response to the deformation of the contact electrode 1, at least one of the first abutting arm 31 and the second abutting arm 32 causes the elastic part 33 to deform and accumulate elastic potential energy.

[0098] Specifically, the number of the first abutting arm 31 and the second abutting arm 32 is one, and they are located at both ends of the elastic member 3 in the axial direction; or, the number of the first abutting arm 31 is two, and they are located at both ends of the elastic member 3 in the axial direction, and the number of the second abutting arm 32 is at least one, and it is located in the middle of the elastic member 3 in the axial direction.

[0099] Of course, in other similar embodiments, the elastic element 3 can also be a leaf spring, a coil spring, a coil spring, or a sheet spring.

[0100] In some embodiments, the mounting bracket 2 includes a bracket body 21 and a limiting part 22, the limiting part 22 being movably connected to the bracket body 21; the contact electrode 1 is mounted on the bracket body 21 through the limiting part 22, and both the contact electrode 1 and the limiting part 22 are connected to the elastic member 3.

[0101] Specifically, there are two limiting parts 22, which are respectively installed on both sides of the bracket body 21, and there are two contact electrodes 1, which are respectively connected to the two limiting parts 22 in a one-to-one correspondence, so as to be installed on both sides of the bracket body 21 and located on both sides in the length direction of the inlet and outlet channel 201.

[0102] In some embodiments, the limiting part 22 is movably connected to the bracket body 21.

[0103] Please see Figure 3 and Figure 4 The limiting part 22 is rotatably connected to the bracket body 21.

[0104] Specifically, the mounting bracket 2 also includes a rotating shaft 23, a limiting part 22 is rotatably connected to the bracket body 21 through the rotating shaft 23, an elastic member 3 is sleeved on the outer periphery of the rotating shaft 23 through the elastic part 33, and the first abutting arm 31 and the second abutting arm 32 of the elastic member 3 abut against the limiting part 22 and the contact electrode 1 respectively; a guide groove 211 is provided on the bracket body 21, and the second connecting member 14 of the contact electrode 1 passes through the guide groove 211.

[0105] The second connector 14 and the guide groove 211 cooperate to limit the deformation / rotation range of the contact electrode 1 under the action of external force.

[0106] During the process from contact between the contact electrode 1 and the working device 200 until their docking is completed, taking the sequential contact between the working device 200 and the first charging contact 12 and the second charging contact 13 in the contact electrode 1 as an example, the above process will be explained in detail:

[0107] As the working equipment 200 gradually approaches, the first charging contact 12 in the contact electrode 1 first contacts the working equipment 200. As the working equipment 200 continues to approach, the contact electrode 1 rotates under the push of the working equipment 200, and the elastic member 3 drives the limiting part 22 to rotate. After the contact electrode 1 and the limiting part 22 rotate to the end of their contact path (at this time, the second connecting member 14 moves relative to the guide groove 211 to abut against the inner wall of the guide groove 211, or the elastic member 3 drives the limiting part 22 to rotate to abut against the support body 21), as the working equipment 200 continues to approach, the first connecting member 11 in the contact electrode 1 deforms under the continuous squeezing force provided by the working equipment 200. In response to the deformation of the contact electrode 1, the elastic member 3 accumulates elastic potential energy. As the working device 200 continues to approach, the portion of the working device 200 that abuts against the first charging contact 12 can move along the surface of the first charging contact 12 to between the first charging contact 12 and the second charging contact 13. At this time, the external force acting on the contact electrode 1 is greatly reduced, and the elastic member 3 can release at least part of the elastic energy. The squeezing pressure between the first charging contact 12 and the working device 200 is effectively relieved, which helps to prevent damage to the contact electrode 1 and the working device 200 caused by excessive squeezing pressure. When the working device 200 continues to approach until the corresponding structure of the working device (e.g., the charging electrode 210) simultaneously contacts the first charging contact 12 and the second charging contact 13, the contact electrode 1 and the working device 200 complete docking and achieve a stable electrical connection, providing reliable contact conditions for charging the working device 200.

[0108] During the docking process, the elastic element 3 plays a good buffering role. It can not only help buffer the impact force generated at the moment of docking and separation between the contact electrode 1 and the working equipment 200, thus improving the stability and reliability of docking, but also protect the contact electrode 1 and the mounting bracket 2 from damage, which helps to improve the service life of the contact electrode 1. At the same time, it can also smoothly transmit the force exerted by the working equipment 200 on the contact electrode 1 to the limiting part 22, so that the contact electrode 1 can smoothly drive the limiting part 22 to rotate.

[0109] Conversely, during the process of contacting the contact electrode 1 and separating from the working device 200, as the working device 200 moves, the contact electrode 1, which is firmly connected to the working device 200 through the first charging contact 12 and the second charging contact 13, can rotate under the drive of the working device 200 and drive the limiting part 22 to rotate through the elastic member 3. The elastic member 3 can be used to ensure the coordination of the movement of each component during this process. After the contact electrode 1 and the limiting part 22 rotate to the end of their contact path (at this time, the second connecting member 14 moves relative to the guide groove 211 to abut against the inner wall of the guide groove 211, or the elastic member 3 drives the limiting part 22 to rotate to abut against the support body 21), as the working device 200 continues to move, the first connecting member 11 in the contact electrode 1 deforms under the pushing force continuously provided by the working device 200. In response to the deformation of the contact electrode 1, the elastic member 3 accumulates elastic potential energy. As the working device 200 continues to move forward, it separates from the second charging contact 13 and the first charging contact 12 in sequence. After the working device 200 separates from the first charging contact 12, it detaches from the contact electrode 1. At this time, the elastic element 3 releases its elastic energy, and the contact electrode 1 returns to its initial shape.

[0110] During the separation process, the elastic element 3 can help control the separation action of the contact electrode 1 from the working device 200, avoid excessive deformation or damage of the contact electrode 1 during the above process, and improve the reusability of the contact electrode 1 to a certain extent.

[0111] Most importantly, the aforementioned elastic element can simplify the structure of the charging component 10 while realizing the deformation recovery and reset of the contact electrode 1. The elastic element 3 cooperates with the contact electrode 1 and the mounting bracket 2, which can effectively improve the docking success rate with the working equipment 200 without complicated external control, and also helps to improve the service life of the charging component 10.

[0112] For details, please refer to Figure 5 and Figure 6 The limiting part 22 is rotatably mounted on the bracket body 21 via the rotating shaft 23, and the contact electrode 1 is fixedly connected to the limiting part 22.

[0113] During the docking process between the working equipment 200 and the charging component 10 via the access channel 201, as the working equipment 200 gradually approaches, the charging electrode 210 of the working equipment 200 first contacts the first charging contact 12 of the contact electrode 1, pushing the contact electrode 1 to move the limiting part 22 along the guide groove 211. During this process, as the working equipment 200 continues to move, the first charging contact 12 and the second charging contact 13 of the contact electrode 1 sequentially abut against the charging electrode 210 of the working equipment 200 to achieve docking. During docking, the first connecting member 11 deforms under the pressure of the charging electrode 210. This deformation can act on the elastic member 3 installed between the contact electrode 1 and the limiting part 22, allowing the elastic member 3 to accumulate elastic potential energy through deformation.

[0114] When the working device 200 separates from the charging component 10 through the inlet / outlet channel 201, the contact electrode 1 moves synchronously along the guide groove 211 toward the moving direction of the working device 200 as the working device 200 moves. During this process, as the working device 200 continues to move, the first charging contact 12 and the second charging contact 13 of the contact electrode 1 separate from the charging electrode 210 of the working device 200 in sequence. During the separation process, the first connecting member 11 recovers its deformation due to the elastic potential energy released by the elastic member 3, and finally allows the contact electrode 1 and the elastic member 3 to return to their initial position and initial shape.

[0115] Compared with the aforementioned structure, the mutual friction between the contact electrode 1 and the charging electrode 210 of the working device 200 is reduced, thereby effectively protecting the contact electrode 1 and reducing the possibility of charging failure caused by wear of the contact electrode 1.

[0116] Please see Figure 4 , Figure 5 and Figure 6 The contact electrode 1 can cause the second charging contact 13 to swing relative to the support body 21 through deformation; in response to the deformation of the contact electrode 1, the elastic element 3 accumulates elastic potential energy; conversely, in response to the restoration of the deformation of the elastic element 3, the contact electrode 1 resets and restores its initial shape.

[0117] In other similar embodiments, the limiting part 22 can be slidably connected to the support body 21. When the contact electrode 1 is subjected to an external force, it can slide relative to the support body 21 under the action of the limiting part 22.

[0118] Specifically, the support body 21 has a sliding groove, and the limiting part 22 can be slidably connected to the support body 21 through the sliding groove. The elastic element 3 is installed between the limiting part 22 and the support body 21. The extension direction of the sliding groove is the same as the extension direction of the inlet / outlet channel 201. When the working device 200 acts on the contact electrode 1 through the charging electrode 210, the contact electrode 1 can drive the limiting part 22 to slide along the sliding groove, and in this process, it squeezes the elastic element 3, so that the elastic element 3 accumulates elastic potential energy. Conversely, the elastic potential energy released by the elastic element 3 can act on the limiting part 22 and the contact electrode 1, so that the limiting part 22 drives the contact electrode 1 to return to its initial position.

[0119] Please see Figure 7 and Figure 8 Along the height direction of the first connector 11 in the contact electrode 1, the limiting part 22 has a limiting groove 221. The contact electrode 1 is fixedly connected to the limiting part 22 through the limiting groove 221. At least one end of the first connector 11 in the height direction is connected to the limiting groove 221. A relief groove 114 is provided on the first connector 11. The elastic member 3 passes through the relief groove 114 and abuts against the first connector 11 and the limiting part 22.

[0120] The limiting groove 221 can be used to position and fix the contact electrode 1 to prevent the contact electrode 1 from shifting or excessively shifting relative to the limiting part 22 under the action of external force. At the same time, the relief groove 114 formed on the first connecting member 11 provides installation space for the elastic member 3. The abutting arm of the elastic member 3 can abut against the limiting part 22 and the contact electrode 1 respectively through the relief groove 114. As the contact electrode 1 deforms, the first abutting arm 31 and the second abutting arm 32 of the elastic member 3 can generate relative displacement and drive the elastic part 33 to deform. At this time, the elastic part 33 generates torque in the torsional direction and stores elastic potential energy.

[0121] It should be noted that as long as the elastic element 3 can achieve the above-mentioned effect, the specific structure of the elastic element 3 is not limited in this application embodiment.

[0122] Specifically, the limiting part 22 includes a limiting side plate 223 and a mounting plate. The mounting plate has mounting holes 222 that rotatably cooperate with the rotating shaft 23. There are two mounting plates, which are respectively connected to both ends of the limiting side plate 223. A limiting groove 221 is formed at the connection between the mounting plate and the limiting side plate 223, which is used to install and fix the first connector 11 in the contact electrode 1.

[0123] The clearance groove 114 formed on the first connector 11 at least penetrates the arc-shaped transition portion 113 (installed within the limiting portion 22 via the limiting groove 221). In this embodiment, please refer to... Figure 7 and Figure 8At least a portion of the relief groove 114 is formed on the first plate 111 and the second plate 112. The first abutting arm 31 of the elastic member 3 passes through the relief groove 114 and abuts against the first connecting member 11, and the second abutting arm 32 passes through the relief groove 114 and abuts against the limiting part 22.

[0124] Figure 9 This is a schematic diagram of the structure of the charging component 10 provided in another embodiment of this application. Figure 10 for Figure 9 A schematic diagram of the structure of contact electrode 1 in the diagram. Figure 11 for Figure 9 A sectional view along the AA direction.

[0125] Please see Figure 9 The charging component 10 provided in this application embodiment includes a contact electrode 1 and a mounting bracket 2. The mounting bracket 2 is a block structure with a certain size, and a portion of the surface of the mounting bracket 2 is recessed inward to form a mounting groove 24 for accommodating a portion of the contact electrode 1. The contact electrode 1 is fixedly mounted on the mounting bracket 2 through the mounting groove 24.

[0126] Please see Figure 9 and Figure 10 The contact electrode 1 includes a first connector 11, a first charging contact 12, and a second charging contact 13, wherein the first charging contact 12 and the second charging contact 13 are independent components spaced apart and maintained at a certain distance in space. The two ends of the first connector 11 in the length direction are respectively used to connect with the first charging contact 12 and the second charging contact 13 to form a relatively stable integrated structure.

[0127] Specifically, in the embodiments of this application, the first connector 11, the first charging contact 12, and the second charging contact 13 are integrally formed.

[0128] In some embodiments, the mounting bracket 2 can be installed on the charging base station 100 using techniques commonly used in related technologies such as detachable connection and adhesion. Alternatively, the mounting bracket 2 can be considered as a non-detachable part of the charging base station 100 (only a portion of the structure of the mounting bracket 2 is shown in the figure).

[0129] The mounting bracket 2 can be configured to face the access channel 201 of the charging base station 100, so that the contact electrode 1 mounted on the mounting bracket 2 faces the access channel 201. When the working equipment 200 enters or exits relative to the charging base station 100 through the access channel 201, the contact electrode 1 mounted on the mounting bracket 2 can be docked with or separated from the working equipment.

[0130] Specifically, the number of mounting brackets 2 and contact electrodes 1 are the same and they are set in a one-to-one correspondence. Please refer to [link / reference]. Figure 9In the figure, a contact electrode 1 is mounted on the mounting bracket 2. On the side of the mounting bracket 2 facing the access channel 201, there are two openings that communicate with the mounting groove 24 inside. The first charging contact 12 and the second charging contact 13 are exposed relative to the mounting bracket 2 through the two openings.

[0131] Along the extension direction parallel to the access passage 201 ( Figure 9 (In the direction indicated by the middle arrow), the end of the mounting bracket 2 has an inclined guide slope, which is inclined along the extension direction of the inlet / outlet channel 201 to better guide the working equipment 200 to dock or separate from the contact electrode 1 on the mounting bracket 2 along the inlet / outlet channel 201.

[0132] Please see Figure 9 and Figure 10 The first connector 11 includes a guide portion 115 and an arc-shaped limiting portion 116, wherein the guide portion 115 is located on the side of the first charging contact 12 facing away from the second charging contact 13, and the arc-shaped limiting portion 116 is located between the first charging contact 12 and the guide portion 115 and connects the first charging contact 12 and the guide portion 115.

[0133] It should be noted that the guide part 115 is exposed relative to the mounting bracket 2, and the arc-shaped limiting part 116 is located in the mounting groove 24 of the mounting bracket 2.

[0134] Please see Figure 11 The guide portion 115 is in contact with the guide slope of the mounting bracket 2, and the arc-shaped limiting portion 116 is located inside the mounting bracket 2 through the limiting post 25 on the mounting bracket 2, and its two ends are respectively connected to the guide portion 115 exposed relative to the mounting bracket 2 and the first charging contact 12.

[0135] The first connector 11 also includes a strip structure for connecting the guide portion 115 and the second charging contact 13. Please refer to [link / reference]. Figure 10 and Figure 11 The strip structure passes through the mounting bracket 2 and one end extends into the mounting groove 24 and is connected to the second charging contact 13.

[0136] The strip structure can be a strip structure extending along a fixed direction, or it can be a folded structure with a certain bending angle. This embodiment does not limit the actual shape of the strip structure.

[0137] It is understood that the charging component 10 provided in this application embodiment includes a contact electrode 1, a mounting bracket 2, and an elastic element 3, wherein the contact electrode 1 includes a first charging contact 12 and a second charging contact 13 spaced apart. By having the contact electrode 1 simultaneously possess two charging structures capable of contact charging, the success rate of docking between the charging base station 100 and the working equipment 200 can be effectively improved. Before the docking confirmation between the contact electrode 1 and the charging electrode 210 of the working equipment 200 is completed, the contact electrode 1 is always in an unpowered state, which helps to further improve the safety of the docking. Most importantly, the first connector 11 of the contact electrode 1 is an elastic structure. The first connector 11 can generate recoverable elastic deformation during the docking process with the working equipment 200. At the same time, in conjunction with the elastic element 3, it can help reduce the friction between the contact electrode 1 and the docking electrode, thereby improving the squeezing force received by the contact electrode 1 during charging to a certain extent, thus increasing the service life of the contact electrode 1, and ultimately improving the performance of the charging component 10.

[0138] Figure 12 This is a schematic diagram of the structure of a charging base station 100 provided in one embodiment of this application.

[0139] Please see Figure 12 This application embodiment also provides a charging base station 100, which is at least used for charging the operating equipment 200.

[0140] Specifically, the charging base station 100 includes a charging component 10 and a charging base 20. The charging component 10 is any of the charging components described above. An access channel 201 for accommodating the working equipment 200 is provided above the charging base 20 and between the charging component 10. When the working equipment 200 moves toward the charging base 20, the working equipment 200 can connect with the first charging contact 12 and the second charging contact 13 in the charging component 10 through the access channel 201 and charge the charging component 10.

[0141] Specifically, the upper surface of the charging base 20 has a docking platform for the operation equipment 200 to travel on, and an access channel 201 is formed above the docking platform and located between the docking platform and the charging component 10. At this time, the contact electrode 1 is suspended above the charging base 20 by the mounting bracket 2.

[0142] The access channel 201 is a space specifically reserved for the operation equipment 200, such as a lawnmower, to enter and exit the charging base station 100. Its shape and size can be designed according to the outline of the operation equipment 200 to ensure that the operation equipment 200 can pass through smoothly. In addition, the access channel 201 formed by the charging component 10 and the charging base 20 not only provides a clear entry and exit path for the operation equipment 200, ensuring that the operation equipment 200 can reach the position for docking with the contact electrode 1, but also provides a certain degree of protection to prevent external debris from entering the access channel 201.

[0143] In this charging base station 100, the structure of the charging component 10 can be referred to the structure of the charging component 10 provided in any of the preceding embodiments, and will not be repeated here.

[0144] When the working equipment 200 enters the access channel 201 and applies a pushing force to the charging component 10, the contact electrode 1 in the charging component 10 can come into contact with the charging component 10 until the first charging contact 12 and the second charging contact 13 both come into contact with the charging electrode 210 of the working equipment 200. At this time, the working equipment 200 and the charging component 10 are docked, and the charging base station 100 can charge the working equipment 200.

[0145] In some embodiments, the charging base may also include a controller, which can initiate a charging delay when the charging electrode 210 of the working device 200 contacts the first charging contact 12 of the charging base station 100. When the charging electrode 210 of the working device 200 contacts the second charging contact 13 of the charging base station 100 (at this time, the charging electrode 210 of the working device 200 is simultaneously in contact with the first charging contact 12 and the second charging contact 13 of the charging base station 100), the charging delay ends, and the charging base begins to charge the working device 200.

[0146] The aforementioned controller can be a microprocessor, the structure and function of which have been disclosed in related technologies and will not be described in detail here.

[0147] For details, please refer to Figure 12 The first charging contact 12 and the second charging contact 13 of the contact electrode 1 are arranged in a direction parallel to the access channel 201. This arrangement can make reasonable use of the space within the access channel 201, not only preventing the contact electrode 1 from excessively encroaching on the access channel 201 and ensuring that the working equipment 200 can move smoothly relative to the access channel 201, but also helping to reduce the size of the charging base station 100, making it more compact and regular, while ensuring that the contact electrode 1 and the working equipment 200 are firmly connected.

[0148] In one feasible implementation, the first charging contact 12 and the second charging contact 13 are disposed toward the middle of the inlet / outlet channel 201 along the length direction of the inlet / outlet channel 201.

[0149] It is understood that the charging base station 100 provided in this application embodiment includes the above-mentioned charging component 10. Therefore, the beneficial effects of the charging base station 100 including at least one or more of the above-mentioned charging components 10 will not be elaborated here. At the same time, the above-mentioned charging component 10 helps to enhance the docking reliability of the charging base station 100, extend the service life of the contact electrode 1, and ultimately improve the user experience of the charging base station 100.

[0150] Figure 13 This is a schematic diagram of the structure of a working device 1000 provided in a certain embodiment of this application. Figure 14 for Figure 13 Top view, Figure 15 for Figure 14 Enlarged view of the structure of region C.

[0151] This application embodiment also provides a working device 1000, including a working device 200 and a charging base station 100 as described in any of the above claims. The charging base station 100 is used to charge the working device 200, and the working device 200 has a charging electrode 210.

[0152] In one possible implementation, the work equipment 200 includes a lawnmower. See also... Figure 13 , Figure 14 and Figure 15 When the lawnmower moves along the access channel 201 until the charging electrode 210 of the lawnmower abuts against the first charging contact 12 and the second charging contact 13 on the contact electrode 1 of the charging base station 100, the charging base station 100 can charge the lawnmower.

[0153] The operating device 1000 provided in this application includes the above-mentioned charging base station 100. Therefore, the operating device 1000 has the beneficial effects of including at least one or more of the above-mentioned charging base stations 100, which will not be repeated here.
