[0003] Currently, due to limitations in structural design and sensing accuracy, there is a risk of the robot and the charging pile deviating from the ideal charging position, resulting in poor contact during the charging process, increased resistance, reduced charging efficiency, and even overheating. Long-term use will damage the robot and the charging pile, posing a safety hazard. Utility Model Content

[0004] The purpose of this application is to provide a charging connection module that, by employing a movable charging electrode with a curved contact surface, effectively resolves the problem of poor contact between the robot and the charging station due to positional deviation, thereby improving charging reliability and efficiency. Another purpose of this application is to provide a robot charging station and a robot.

[0005] To achieve the above objectives, the present application provides a charging connection module, comprising:

[0006] A fixed base, provided on one of the charging station and the robot;

[0007] The first charging electrode and the second charging electrode are both movably arranged on the fixing seat, and the first charging electrode and the second charging electrode both have a contact surface for electrically connecting to the charging pile and the charging end of the other of the robots, and the contact surface is a curved surface.

[0008] In some embodiments, the first charging electrode and / or the second charging electrode includes a charging bracket and a charging electrode piece mounted on the charging bracket, the charging bracket is movably disposed on the fixing seat, and the charging electrode piece has the contact surface.

[0009] In some embodiments, the charging bracket includes a push rod, which is telescopically movable relative to the fixing seat, and the contact surface is located at the end of the push rod along the telescopic movement direction.

[0010] In some embodiments, the push rod is provided with a protrusion, the charging electrode is provided with a groove, and the protrusion cooperates with the groove.

[0011] In some embodiments, the first charging electrode and the second charging electrode telescope along a first direction and are spaced apart along a second direction; within a plane formed by the first direction and the second direction, the cross-sectional shape of the contact surface is a curve, and the curve bends away from the fixing seat.

[0012] In some embodiments, the contact surface is a curved surface, and the curved surface forms an arc in a plane in the first direction and the second direction and extends along the second direction.

[0013] In some embodiments, the charging connection module further includes:

[0014] An elastic member is provided on the fixing seat, and is used to drive the first charging electrode and / or the second charging electrode away from the fixing seat.

[0015] In some embodiments, the elastic member is a spring, a first end of the spring is fixed to the fixing seat, and a second end of the spring is fixed to the second end of the first charging electrode and / or the second charging electrode.

[0016] The present application also provides a robot charging pile, including the above-mentioned charging connection module.

[0017] The present application also provides a robot comprising the above-mentioned charging connection module.

[0018] Compared with the above-mentioned background technology, the charging connection module provided in this application mainly includes a fixing seat, a first charging electrode and a second charging electrode. The fixing seat is arranged on one of the charging pile and the robot; the first charging electrode and the second charging electrode are both movably arranged on the fixing seat, and the first charging electrode and the second charging electrode both have a contact surface for electrically connecting to the charging end of the other of the charging pile and the robot, and the contact surface is a curved surface.

[0019] Existing robot charging technology requires precise alignment of the robot with the charging electrode on the charging station for effective charging. However, due to limitations in robot positioning accuracy, the robot may deviate from its position during charging, resulting in poor contact between the charging electrodes. This poor contact not only reduces charging efficiency but can also cause overheating due to increased contact resistance. In the long term, this can damage the charging port and even pose a safety hazard.

[0020] To address the problem of poor contact between the robot and the charging station due to positional deviation in the prior art, the charging connection module provided in this application adopts an innovative design. The module mainly includes a fixing base, a first charging electrode, and a second charging electrode. The fixing base is installed on either the charging station or the robot, and the first charging electrode and the second charging electrode are flexibly mounted on the fixing base. These charging electrodes each have a contact surface designed as a curved surface for achieving electrical connection with the charging terminal of the charging station or the robot.

[0021] The key advantage of this design lies in its flexibility and adaptability. Even if the robot or charging station deviates slightly during docking, the curved contact surface on the charging electrode maintains effective contact with the charging terminal. This curved contact surface allows for effective docking at multiple angles and orientations, maintaining a stable electrical connection in all positions and ensuring a continuous and reliable charging process.

[0022] Combined with the above structure and process description, it can be seen that the charging connection module has at least the following beneficial effects: the charging connection module effectively solves the problem of poor contact between the robot and the charging pile caused by position deviation by adopting a movable charging electrode with a curved contact surface in the charging connection module, thereby improving the reliability and efficiency of charging.

[0038] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0039] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0040] Please refer to Figures 1 to 3 ,in, Figure 1 This is a schematic diagram of a charging connection module provided in an embodiment of the present application. Figure 2 This is a schematic diagram of the charging electrode provided in the embodiment of the present application. Figure 3 This is a rendering of the charging connection module provided in an embodiment of the present application.

[0041] exist Figures 1 to 2 The coordinate axes are indicated in the figure, and the directions indicated by the coordinate axes are consistent with the directions described in the present application. The coordinate axis x represents the second direction, which is also the width direction and the left-right direction, with reference to the structural shape in the figure. The coordinate axis y represents the first direction, which is also the thickness direction and the front-back direction, with reference to the structural shape in the figure.

[0042] In a first specific embodiment, the charging connection module 100 provided in the embodiment of the present application mainly includes a fixing seat 1 and a charging electrode 2, the charging electrode 2 includes a first charging electrode 21 and a second charging electrode 22, the fixing seat 1 is arranged on one of the charging pile and the robot; the first charging electrode 21 and the second charging electrode 22 are both movably arranged on the fixing seat 1, and the first charging electrode 21 and the second charging electrode 22 both have a contact surface 2021 for electrically connecting to the charging end 5 of the other of the charging pile and the robot, and the contact surface 2021 is a curved surface.

[0043] It should be noted that the setting position of the charging connection module 100 is not restricted, and it can be a robot charging pile or a robot; the first direction and the second direction are not restricted. Taking the accompanying drawings as an example, the first direction can be the horizontal left and right direction, and the second direction can be the longitudinal direction, that is, the front and back direction perpendicular to the horizontal.

[0044] Taking the robot charging pile as a fixed type as an example, the robot moves to achieve recharging on the robot charging pile. In the first case, the charging connection module 100 is set on the robot charging pile. When the robot is recharging, the robot moves to the robot charging pile and aligns the charging positions of the two. At this time, the first charging electrode 21 and the second charging electrode 22 can be adjusted flexibly to adapt to the charging position on the robot, while the curved contact surface 2021 maintains contact and conduction at the charging positions of the two. In the second case, the charging connection module 100 is set on the robot. When the robot is recharging, the robot moves to the robot charging pile and aligns the charging positions of the two. At this time, the first charging electrode 21 and the second charging electrode 22 can be adjusted flexibly to adapt to the charging position on the robot charging pile, while the curved contact surface 2021 maintains contact and conduction at the charging positions of the two. It can be seen that whether the charging connection module 100 is set on the robot charging pile or the charging connection module 100 is set on the robot, the robot can be recharged on the robot charging pile through the charging connection module 100.

[0045] Existing robot charging technology requires precise alignment of the robot with the charging electrode on the charging station for effective charging. However, due to limitations in robot positioning accuracy, the robot may deviate from its position during charging, resulting in poor contact between the charging electrodes. This poor contact not only reduces charging efficiency but can also cause overheating due to increased contact resistance. In the long term, this can damage the charging port and even pose a safety hazard.

[0046] To address the existing problem of poor contact between the robot and the charging station due to positional deviation, the charging connection module 100 provided in this application employs an innovative design. The module primarily comprises a mounting base 1, a first charging electrode 21, and a second charging electrode 22. The mounting base 1 is mounted on either the charging station or the robot, while the first and second charging electrodes 21 and 22 are flexibly mounted on the mounting base 1. Each of these charging electrodes has a curved contact surface 2021 for electrical connection to the charging terminal 5 of either the charging station or the robot.

[0047] The key advantage of this design lies in its flexibility and adaptability. Even if the robot or charging station deviates slightly during docking, the curved contact surface 2021 on the charging electrode can still maintain effective contact with the charging terminal 5. The curved contact surface 2021 allows for effective docking at multiple angles and orientations, maintaining a stable electrical connection in various positions and ensuring a continuous and reliable charging process.

[0048] In combination with the above structure and process description, it can be seen that the charging connection module 100 has at least the following beneficial effects: the charging connection module 100 effectively solves the problem of poor contact between the robot and the charging pile caused by position deviation by adopting a movable charging electrode with a curved contact surface 2021 in the charging connection module 100, thereby improving the reliability and efficiency of charging.

[0049] Please refer to Figures 4 and 5 ,in, Figure 4 A schematic diagram of a robot charging station provided in an embodiment of the present application. Figure 5 Schematic diagram of the charging connection module and robot charging module provided in an embodiment of the present application.

[0050] like Figures 1 to 5 As shown, the charging connection module 100 is set on the robot charging pile; corresponding to the robot charging pile and the charging connection module 100, the robot that is recharged on the robot charging pile is provided with a robot charging module 200. When the robot is recharged on the robot charging pile, the robot charging module 200 is in contact and conductive with the charging connection module 100. Through the curved surface features on the charging connection module 100, stable contact can be provided at different angles, and the contact area is kept constant, and the resistance in the charging circuit is kept consistent, thereby ensuring the continuity and reliability of charging.

[0051] It should be noted that the scope of this application is not limited to Figures 1 to 5 The display situation of the charging connection module 100 is also within the scope of the description of this application, as for the situation where the charging connection module 100 is set on the robot.

[0052] Please continue to refer to Figure 2 In some embodiments, the first charging electrode 21 and / or the second charging electrode 22 includes a charging bracket 201 and a charging electrode piece 202 mounted on the charging bracket 201 . The charging bracket 201 is movably disposed on the fixed base 1 , and the charging electrode piece 202 has a contact surface 2021 .

[0053] In this embodiment, the charging connection module 100 is designed with a first charging electrode 21 and a second charging electrode 22. Each electrode includes a charging bracket 201 and a charging electrode piece 202. The charging bracket 201 serves as a support structure and is movably mounted on the fixing base 1, allowing the charging electrode piece 202 to be moved and adjusted as necessary.

[0054] The charging electrode 202 is mounted on the charging bracket 201 and has a contact surface 2021, which is the key component for electrical connection with the charging terminal 5 of the robot or charging station. The curved surface 2021 increases the contact area with the charging terminal 5, maintaining a stable electrical connection even with positional deviations.

[0055] This design allows the charging electrode 202 to adapt to different charging environments and docking conditions, improving the flexibility and reliability of the charging connection. Therefore, regardless of the positioning of the robot or charging station, the charging connection module 100 can ensure an effective charging connection, solving the problem of poor contact caused by position deviation in traditional technologies.

[0056] In some embodiments, the charging bracket 201 includes a push rod 2011 , which is telescopically movable relative to the fixing base 1 , and the contact surface 2021 is located at the end of the push rod 2011 along the telescopic movement direction.

[0057] In this embodiment, the charging stand 201 further includes a push rod 2011, which provides additional flexibility and adjustability for the charging electrode. The push rod 2011 is capable of telescopic movement relative to the mounting base 1, meaning that the push rod 2011 can be pushed in or pulled out along its length within the mounting base 1.

[0058] Contact surface 2021 is located at the end of push rod 2011 and is arranged along the direction of telescopic movement. This design allows contact surface 2021 to extend and retract in front of the charging terminal 5 of the robot or charging station to accommodate different docking distances and positions. The telescopic movement of push rod 2011 allows contact surface 2021 to move closer to or further away from the mounting base 1 as needed, thereby better accommodating alignment errors between the robot and the charging station.

[0059] This design of push rod 2011 not only provides precise control over the position of charging electrode 202, but also ensures that even if positional deviation occurs during docking, contact surface 2021 can maintain a stable connection with the charging terminal 5 of the robot or charging station. Therefore, this structure significantly improves the reliability of the charging connection and the efficiency of the charging process.

[0060] In some embodiments, the push rod 2011 is provided with a protrusion 20111 , and the charging electrode 202 is provided with a groove 2022 , and the protrusion 20111 cooperates with the groove 2022 .

[0061] In this embodiment, the design of the first charging electrode 21 and the second charging electrode 22 takes into account the convenience of assembly and positioning, which is achieved by providing protrusions 20111 on the charging electrode piece 202. These protrusions 20111 cooperate with the grooves 2022 on the charging electrode piece 202 to accurately position the charging electrode piece 202, thereby simplifying the assembly process and improving the stability of the overall structure.

[0062] Optionally, the protrusions 20111 are preferably provided on the upper and lower sides of the charging electrode 202 , which not only facilitates cooperation with the groove 2022 of the charging electrode 202 , but also maintains a neat appearance of the charging electrode 202 .

[0063] In some embodiments, the first charging electrode 21 and the second charging electrode 22 extend and retract along the first direction and are spaced apart along the second direction; within the plane formed by the first and second directions, the cross-sectional shape of the contact surface 2021 is a curve, and the curve bends away from the fixing seat 1.

[0064] In this embodiment, the design of the charging connection module 100 allows the first charging electrode 21 and the second charging electrode 22 to telescope in a first direction while being spaced apart in a second direction. This layout ensures that the charging electrodes can freely extend in one direction while remaining positioned in another, thereby accommodating charging terminals 5 in different positions. The cross-sectional shape of the contact surface 2021 is designed to be curved. In particular, this curved design causes the contact surface 2021 to protrude outward, resembling an arched surface, with its center or most protruding portion being the farthest from the fixing base 1. This protruding curved surface provides a larger contact area, allowing the charging terminal 5 to maintain a stable connection with the contact surface 2021 even in the presence of positional or angular deviations.

[0065] Furthermore, this curved design increases the flexibility and adaptability of the charging electrode, allowing it to better conform to the surface shape of charging terminal 5. The elastic deformation of contact surface 2021 helps absorb impact and misalignment during docking, thereby improving the reliability of the charging connection. This design not only ensures efficient and stable charging under various docking conditions, but also extends the service life of the charging connection module, significantly improving the practicality and efficiency of the robot charging system.

[0066] In some embodiments, the contact surface 2021 is an arc surface, and an arc formed in a plane in the first direction and the second direction by the arc surface extends along the second direction.

[0067] In this embodiment, the contact surface 2021 is designed as an arc surface, which is a special form of curved surface in which the arc extends along the second direction. This design allows the contact surface 2021 to provide a continuous and soft contact area, which helps to achieve a smooth transition and connection when the robot or the charging terminal 5 of the charging station is docked.

[0068] The curved surface design is particularly helpful in absorbing linear or rotational deviations during the docking process, because the extension of the curved surface along the second direction provides a larger contact angle range. This means that no matter how slightly the charging terminal 5 deviates from the expected docking position, the curved contact surface 2021 can effectively adjust to maintain contact with the charging terminal 5.

[0069] Furthermore, the continuous nature of the curved surface 2021 means that during telescoping, the contact surface can evenly transfer power, reducing electrical resistance and overheating issues caused by uneven contact. This design not only improves charging efficiency but also helps enhance charging safety.

[0070] In some embodiments, the charging connection module 100 further includes:

[0071] The elastic member 5 is provided on the fixing base 1 , and is used to drive the first charging electrode 21 and / or the second charging electrode 22 to move away from the fixing base 1 .

[0072] In this embodiment, the main function of the elastic member 5 is to provide power to the charging electrodes 2 (not limited to the first charging electrode 21 or the second charging electrode 22), so that they can extend from the fixing seat 1 and move to the appropriate position to provide a contact and tight effect during charging.

[0073] The elastic member 5 can be any mechanism capable of providing the required force, including an active drive mechanism such as an electric push rod or a passive drive mechanism such as a spring. Active drive mechanisms allow for more precise control of the movement and position of the charging electrode 2, while passive drive mechanisms rely on elastic force to achieve extension of the charging electrode 2.

[0074] by Figure 1 For example, two elastic members 5 may be provided, each corresponding to the first charging electrode 21 and the second charging electrode 22. This configuration ensures that both charging electrodes 2 can be stably extended and maintained in the appropriate position, thereby improving the reliability and efficiency of charging.

[0075] By using the elastic member 5, the charging connection module 100 can adapt to various position deviations that may occur when the robot is charging, ensuring that the charging electrode 2 can maintain stable contact with the charging interface of the robot, thereby achieving an efficient and safe charging process.

[0076] by Figure 3 For example, in combination with the case where the charging connection module 100 is set on the robot charging pile, the robot is provided with a robot charging module 200, and the robot charging module 200 is provided with two charging terminals 5, and the two charging terminals 5 are in contact and conductive with the first charging electrode 21 and the second charging electrode 22. When the robot charging module 200 is tilted relative to the charging connection module 100, the charging terminals 5 are in a tilted state, resulting in inconsistent expansion and contraction of the first charging electrode 21 and the second charging electrode 22. However, the first charging electrode 21 and the second charging electrode 22 can both maintain good contact with the charging terminals 5. In particular, the elastic member 5 drives the first charging electrode 21 and the second charging electrode 22 to press against the charging terminal 5. At the same time, the curved surface features of the contact surface 2021 can provide stable contact at different angles, maintain a constant contact area, and keep the resistance in the charging circuit consistent, thereby ensuring the continuity and reliability of charging.

[0077] In some embodiments, the elastic member 5 is a spring, a first end of the spring is fixed to the fixing seat 1 , and a second end of the spring is fixed to the second end of the first charging electrode 21 and / or the second charging electrode 22 .

[0078] In this embodiment, the elastic member 5 uses a spring as its power source. This design utilizes the spring's elasticity to achieve the extension and retraction of the charging electrode 2. The first end of the spring is fixed to the fixing base 1, while the second end is connected and fixed to the second end of the first charging electrode 21 and / or the second charging electrode 22. This arrangement allows the spring to provide a pushing force when the charging electrode 2 needs to be extended, and a pulling force when the charging electrode 2 needs to be retracted.

[0079] like Figure 1 As shown, the first end of the spring, i.e., the rear end, is fixed to the fixing seat 1 , and the second end of the spring, i.e., the front end, is connected to the corresponding charging electrode 2 .

[0080] In some cases, two springs may be provided, the first ends of the two springs being fixed on the fixing seat 1, the second end of the first spring being connected and fixed to the first charging electrode 21, and the second end of the second spring being connected and fixed to the second charging electrode 22, and the two springs respectively play a driving role on the first charging electrode 21 and the second charging electrode 22.

[0081] When the robot needs to charge, the spring's elastic force causes the first and second charging electrodes 21 and 22 to extend outward until they contact the robot's charging point, i.e., the charging port 5. Once contact is established, the spring's elastic force helps the charging electrodes 2 maintain stable contact with the robot's charging port, ensuring a continuous and reliable charging process.

[0082] Furthermore, due to the spring's elastic properties, the charging electrode 2 maintains contact even when the robot deviates from its position, as the spring provides a certain range of expansion and contraction to accommodate the robot's alignment errors. This design improves the charging system's fault tolerance, enabling efficient charging even when the robot's positioning is not very precise.

[0083] Please continue to refer to Figure 1 In some embodiments, the fixing base 1 includes:

[0084] The housing 101 is provided with a sliding cavity 1011 and an outlet 1012. The first charging electrode 21 and the second charging electrode 22 are disposed in the sliding cavity 1011. The outlet 1012 is in communication with a first end of the sliding cavity 1011. The first charging electrode 21 and the second charging electrode 22 extend through the outlet 1012.

[0085] The cover plate 102 is connected to the housing 101 , and blocks the second end of the sliding cavity 1011 .

[0086] In this embodiment, the housing 101 is internally designed with two sliding cavities 1011, spaced apart along the second direction, to accommodate the first charging electrode 21 and the second charging electrode 22, respectively. The charging brackets 201 for the first and second charging electrodes 21, 22 are equipped with connected push rods 2011 and movable seats 2012. The push rods 2011 extend through the outlet 1012, and the movable seats 2012 slide along the sliding cavities 1011. This design allows the charging electrodes 2 to slide freely within the sliding cavities 1011, accommodating the displacement caused by contact during charging of the robot.

[0087] Exit 1012 is a structure that faces the robot charging station and the robot charging position. Exit 1012 is directly connected to the sliding cavity 1011, allowing the first charging electrode 21 and the second charging electrode 22 to extend. The location and design of exit 1012 ensure that the charging electrode 2 can smoothly contact the robot charging position, achieving an effective charging connection.

[0088] To protect the charging electrode 2 within the sliding cavity 1011, limit its maximum rearward movement, and prevent the ingress of dust and other impurities, the other end of the sliding cavity 1011 is sealed by a cover 102. Cover 102 is connected to the housing 101, forming a closed protective space that ensures the cleanliness of the charging electrode 2 and the stability of the charging process.

[0089] In addition, the protrusion 20111 is located on the side of the housing 101 facing the cover 102. The position of the protrusion 20111 is limited to the side of the housing 101 facing the cover 102, ensuring that the protrusion 20111 does not extend outside the sliding cavity 1011, thereby providing a maximum forward movement limit for the charging electrode 2.

[0090] In some cases, a positioning column is provided on the side of the cover 102 facing the shell 101. Taking the elastic member 5 as a spring as an example, the first end of the spring, i.e., the rear end, is fixed on the positioning column, and the second end of the spring, i.e., the front end, is connected to the corresponding charging electrode 2.

[0091] Please continue to refer to Figure 2 In some embodiments, the first charging electrode 21 and the second charging electrode 22 are both provided with a charging electrode piece 202 , the end of the charging electrode piece 202 extending out of the outlet 1012 is provided with a contact surface 2021 , and the end of the charging electrode piece 202 located inside the shell 101 is provided with a conductive connector 2023 .

[0092] In some cases, to improve manufacturing efficiency and ensure the reliability of electrical connections, the charging electrode 202 can be designed in an integrated manner. The integrated molding process can reduce the number of connection points between components, reduce contact resistance, and improve the stability and durability of the overall structure.

[0093] In some embodiments, the charging connection module 100 further includes:

[0094] The sensor assembly is provided on the fixing seat 1 and is used to realize signal reception between the robot charging pile and the robot to obtain the charging position of the robot charging pile and the robot.

[0095] In this embodiment, the charging connection module 100 further integrates a sensor assembly, which is mounted on the fixing base 1. The core function of the sensor assembly is to improve the accuracy and efficiency of the charging process between the robot and the robot charging station. By enabling signal reception between the robot charging station and the robot, it ensures that the first charging electrode 21 and the second charging electrode 22 are correctly aligned with the charging terminal 5.

[0096] The sensor component can implement this function using a variety of technologies, including but not limited to visual sensors and infrared sensors. For example, an infrared sensor can be designed as either a transmitter or a receiver, depending on the system design requirements. If designed as a transmitter, the sensor component sends infrared signals to the robot, which receives these signals through its onboard infrared receiver and adjusts its position accordingly to align with the charging pad.

[0097] In some embodiments, the sensor assembly includes an infrared emitting device 4 and / or an infrared receiving device 6 .

[0098] In this embodiment, the sensor assembly can be configured as one or both of the infrared transmitter 4 and the infrared receiver 6 to achieve precise alignment between the robot charging station and the robot. This configuration allows the charging connection module 100 to effectively communicate with the robot charging module 200 on the robot charging station.

[0099] Taking the sensor component as the infrared emitting device 4 as an example, the charging connection module 100 is set on the robot charging pile, so the infrared emitting device 4 is located at the robot charging pile, and correspondingly, the infrared receiving device 6 is set in the robot charging module 200 of the robot.

[0100] When the robot approaches the robot charging station for charging, infrared receiver 6 captures the signal from infrared transmitter 4. The robot's control system analyzes the current position and alignment based on the received signal. If any deviation is found, the system automatically adjusts the robot's position until the charging electrode 13 on the robot charging module 200 is precisely aligned with the charging electrodes 2 and 3 in the charging connection module 100 on the robot charging station.

[0101] Please continue to refer to Figure 4 , the present application also provides a robot charging pile, including the above-mentioned charging connection module 100.

[0102] The robot charging pile should have all the beneficial technical effects of the above-mentioned charging connection module 100, which will not be described in detail here.

[0103] When the robot needs to charge, it moves to the robot charging station. The robot's charging module 200 docks with the charging connection module 100. During this process, the infrared transmitter 4 located in the charging connection module 100 sends signals to the robot, which are then received by the infrared receiver 6 on the robot. Based on these signals, the robot can accurately determine its position relative to the charging station and make the necessary adjustments to ensure that the charging electrode 13 on the robot's charging module 200 is aligned with the first charging electrode 21 and the second charging electrode 22 in the charging connection module 100.

[0104] Once the robot is correctly positioned, the first charging electrode 21 and the second charging electrode 22 are pushed toward the charging terminal 5 by the elastic member 5, usually a spring, ensuring the transmission of electrical energy. Through the charging electrode 202, an electrical energy transmission path is formed between the contact surface 2021 and the conductive connector 2023, allowing current to flow from the charging station through the charging electrode 202 and ultimately to the robot.

[0105] During the contact process, the protrusions 20111 on the first charging electrode 21 and the second charging electrode 22 cooperate with the grooves 2022 on the charging electrode piece 202 to ensure the stable positioning of the charging electrode piece 202. The curved contact surface 2021 design allows for stable electrical contact even with a certain position deviation, ensuring continuous and reliable charging.

[0106] In addition, the fixing base 1 of the charging connection module 100 provides protection for the charging electrode to prevent dust and other impurities from entering, while also limiting the movement of the charging electrode, ensuring the stability of the charging electrode when extending and retracting.

[0107] The entire charging process is automated. Once the robot is positioned, the charging connection module 100 automatically aligns the charging electrodes and transmits power, eliminating the need for human intervention. This significantly improves charging efficiency and convenience. In this way, the robot charging station not only provides a reliable charging method but also ensures safety and efficiency during the charging process.

[0108] The present application also provides a robot, comprising the above-mentioned charging connection module 100 .

[0109] In addition to the embodiment of applying the charging connection module 100 to a robot charging station, this application also covers the solution of integrating the charging connection module 100 into the robot. In this case, the robot is directly equipped with the charging connection module 100, allowing the robot to charge at different charging stations or charging stations.

[0110] When the robot needs to charge, it moves to a compatible charging station or charging pile. At this point, the robot's internal charging connection module 100 extends its first charging electrode 21 and second charging electrode 22, docking with the charging position on the charging station or charging pile. During the docking process, the sensor assembly on the charging connection module 100 ensures that the charging electrode is accurately aligned with the charging port on the charging station.

[0111] Once aligned, the robot's internal elastic member 5 (e.g., a spring) pushes the first and second charging electrodes 21 and 22 into close contact with the charging port of the charging station, establishing a stable power transmission path. The curved contact surface 2021 ensures a stable charging connection even with slight misalignment during docking.

[0112] During charging, the charging electrode 202 on the charging connection module 100 on the robot is responsible for transmitting electrical energy from the charging station to the robot. The entire charging process is also automatic, without the need for human intervention, ensuring convenient and efficient charging.

[0113] This design allows the robot to be charged flexibly in a variety of charging environments, increasing the robot's range of use and flexibility. Furthermore, the charging connection module 100 integrated into the robot also helps simplify the design of charging stations, as the complex charging docking mechanism is already integrated into the robot.
