Description

Technical Field

[0001] This application relates to the field of robot charging technology, and in particular to power supply devices, charging piles, and robots. Background Technology

[0002] With the development of robotics technology, autonomous charging has become an indispensable function of modern robot products. Specifically, autonomous charging refers to the robot's ability to navigate autonomously to a charging station and charge its internal battery through physical contact between the robot's electrodes and the charging station's electrodes, thereby ensuring the required battery life for the robot's operation.

[0003] To ensure effective contact between the robot's electrodes and the charging station electrodes, related technologies typically employ a "surface-to-surface" contact method for charging. However, in some high-dust operating scenarios, when dust accumulates on the robot's electrodes, the dust can form a barrier layer between the main body electrodes and the charging station electrodes, leading to poor contact or even failure between the two. Ultimately, this prevents the robot from charging, severely impacting the user experience. Utility Model Content

[0004] Therefore, it is necessary to provide a power supply device, a charging station, and a robot to address the problem of dust accumulation affecting robot charging.

[0005] In a first aspect, this application provides a power supply device, the power supply device comprising:

[0006] Carrier component;

[0007] An electrode assembly includes an electrode body and a conductive protrusion. The electrode body has a first side and a second side opposite to each other along the thickness direction of the electrode assembly. The first side is connected to the support component, and the conductive protrusion protrudes from the second side.

[0008] An elastic component is elastically connected between the support component and the electrode component, allowing the electrode component to move relative to the support component.

[0009] In one embodiment, the side of the conductive protrusion away from the electrode body is configured as several sharp points.

[0010] In one embodiment, the conductive protrusion is configured as a plurality of protrusions, which are sequentially connected.

[0011] In one embodiment, the conductive protrusion has a first surface and a second surface opposite to each other along the thickness direction, the first surface being connected to the second surface; the projected area of ​​the second surface along the thickness direction is smaller than the projected area of ​​the first surface along the thickness direction.

[0012] In one embodiment, the conductive protrusion is configured as a plurality of spaced quadrangular prisms.

[0013] In one embodiment, the thickness of the electrode assembly gradually decreases along the length of the electrode assembly.

[0014] In one embodiment, the elastic component includes a first elastic element and a second elastic element, the length of the first elastic element being greater than the length of the second elastic element, the first elastic element being connected to one end of the bearing component and the first side, and the second elastic element being connected to the other end of the bearing component and the first side.

[0015] Secondly, this application also provides a charging pile, including a charging pile body and a power supply device as described in the above embodiments. The charging pile body is capable of being connected to mains power, and the electrode assembly is electrically connected to the output circuit within the charging pile body.

[0016] Thirdly, this application also provides a robot, including a robot body and a power supply device as described in the above embodiments, wherein the power supply device is disposed in the robot body and connected to a battery inside the robot body.

[0017] The power supply device, charging pile, and robot provided in this application, during the automatic charging process of the robot to the charging pile, are subject to the limitation of the robot's positioning device recognition accuracy. There will inevitably be a positional deviation between the robot's body electrodes and the charging pile electrodes. The elastic deformation of the elastic component generates an adaptive floating amount, which will inevitably cause dynamic sliding when the two sets of electrodes come into contact. The solution of this application designs the surface of the electrode assembly as a convex structure. On the one hand, reducing the contact area can reduce the probability of dust blockage. On the other hand, the mechanical action during the sliding process can achieve the scraping and peeling of accumulated dust, thereby effectively solving the problem of charging failure caused by poor contact under heavy dust conditions.

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] Figure 1 A schematic diagram of the structure of a power supply device 100 according to an embodiment of the present application is shown. The power supply device 100 includes a support component 110, an electrode component 120, and an elastic component 130.

[0036] Please combine Figure 2 Specifically, the electrode assembly 120 includes an electrode body 121 and a conductive protrusion 122. The electrode body 121 has a first side 121a and a second side 121b opposite to each other along the thickness direction X of the electrode assembly 120. The first side 121a is connected to the support assembly 110, and the conductive protrusion 122 protrudes from the second side 121b.

[0037] It is understood that the electrode assembly 120 includes a positive electrode 1201 and a negative electrode 1202, and both the positive electrode 1201 and the negative electrode 1202 are capable of being configured with the electrode assembly 120 in the above embodiments.

[0038] The elastic component 130 is elastically connected between the support component 110 and the electrode component 120, allowing the electrode component 120 to move relative to the support component 110. With this configuration, under contact pressure, the elastic component 130 can generate an adaptive floating amount within a predetermined range through controlled deformation.

[0039] In this embodiment, the power supply device 100, during the automatic charging process of the robot, is limited by the recognition accuracy of the robot positioning device, and there will inevitably be a positional deviation between the robot body electrode and the charging pile electrode. Under the action of contact pressure, the elastic component 130 elastically deforms to generate an adaptive floating amount, which will inevitably cause dynamic sliding when the two sets of electrodes come into contact. This solution designs the surface of the electrode component 120 as a convex structure. On the one hand, reducing the contact area can reduce the probability of dust blockage. On the other hand, the mechanical action during the sliding process can achieve the scraping and peeling of accumulated dust, thereby effectively solving the problem of charging failure caused by poor contact between electrodes under heavy dust conditions.

[0040] To facilitate understanding, the following explanation will focus on the application scenario of the power supply device 100 in a charging pile:

[0041] like Figure 3 As shown, this application provides a charging pile, including a power supply device 100 and a charging pile body. The charging pile body can be connected to mains power, and the electrode assembly 120 of the power supply device 100 is electrically connected to the output circuit within the charging pile body. When the robot automatically charges the charging pile, the conductive protrusion 122 on the electrode body 121 of the charging pile abuts against the charging electrode surface 210 of the robot, forming a charging circuit of the charging pile body, the power supply device 100 (electrode assembly 120), and the robot, thereby realizing the charging of the robot.

[0042] During the automatic charging and docking process of the robot, due to recognition errors, when the charging electrode surface 210 on the robot body 200 docks with the electrode assembly 120, the elastic component 130 can drive the electrode assembly 120 to move elastically. This causes a certain positional and / or angular displacement of the charging electrode surface 210 relative to the electrode assembly 120, resulting in slippage and scratching of the charging electrode surface 210. The convex structure of the conductive protrusion 122 scrapes and removes the accumulated dust on the charging electrode surface 210, reducing the obstructive effect of the accumulated dust on the charging electrode surface 210 and the electrode assembly 120, improving the problem of poor contact, and ensuring stable charging.

[0043] It should be noted that the above implementation method uses the power supply device 100 applied to the charging pile only for the purpose of introducing the first scheme and making it easier to understand. In fact, the power supply device 100 can be applied to at least one of the charging electrodes of the robot body and the charging pile electrodes.

[0044] Please continue reading. Figure 2 In some embodiments, the conductive protrusion 122 is configured as a plurality of protrusions 1221, which are connected in sequence. Specifically, the plurality of protrusions 1221 are arranged side by side, and a groove is formed between any two protrusions 1221. The tip of each protrusion 1221 constitutes a scraping point.

[0045] Please combine Figure 3 With this configuration, the conductive protrusion 122, through the arrangement of multiple protrusions 1221, forms a "line-to-surface" contact when it comes into contact with the charging electrode surface 210. Under the elasticity of the elastic component, the electrode assembly 120 scrapes the dust on the charging electrode surface 210, thus improving the dust removal effect. Furthermore, the conductive protrusion 122, formed by multiple protrusions 1221, has numerous grooves, thereby reducing the contact area between the conductive protrusion 122 and the charging electrode surface 210, and consequently reducing the impact of dust on the charging electrode surface 210 on the charging of the electrode assembly 120.

[0046] exist Figures 1 to 3In this embodiment, specifically, the protruding tooth 1221 is configured as a triangular prism structure, with any one side edge along the length of the triangular prism forming the tooth tip of the protruding tooth 1221. The face opposite to this side edge is disposed on the second side 121b of the electrode body 121. It is understood that the shape of the protruding tooth 1221 can also be configured as at least one of a pentagonal prism, a heptagonal prism, etc., and is not limited here. Any one side edge of the pentagonal prism or heptagonal prism structure forms the tooth tip of the protruding tooth 1221, and the face opposite to this side edge is disposed on the second side 121b of the electrode body 121. In this way, when the tooth-shaped conductive protrusion 122 contacts the charging electrode surface 210, it can form multiple protruding tooth tips. Under the action of the elastic component 130, the tooth tips of the protruding tooth 1221 effectively scrape away the dust adhering to the charging electrode surface 210, thereby ensuring that multiple lines and surfaces can be well contacted between the conductive protrusion 122 and the charging electrode surface 210 to achieve stable charging.

[0047] Optionally, in one embodiment, a plurality of protrusions 1221 are sequentially connected along the length direction Y or the width direction Z to form a conductive protrusion 122. The specific arrangement of the protrusions 1221 can be flexibly set according to the actual situation.

[0048] Please see Figures 4 to 5 In another embodiment, the end of the conductive protrusion 122 furthest from the electrode body 121 is configured with a plurality of pointed tips 122a. Thus, by providing the pointed tips 122a, when the conductive protrusion 122 contacts the charging electrode surface 210, a point-to-surface contact is formed, resulting in more scraping points on the charging electrode surface 210 by the conductive protrusion 122, a greater scraping effect on dust, and consequently, improved dust-cleaning ability of the conductive protrusion 122 while ensuring good contact.

[0049] exist Figures 4 to 5 In the illustrated embodiment, specifically, the conductive protrusion 122 has a square pyramid structure, with any vertex of the pyramid forming the tip 122a of the conductive protrusion 122. The base surface opposite to this vertex is disposed on the second side 121b of the electrode body 121. It is understood that the shape of the conductive protrusion 122 with the tip 122a can also be at least one of a conical, triangular, or pentagonal pyramid structure, and is not limited thereto. Any vertex of the conical, triangular, or pentagonal pyramid structure forms the tip 122a of the conductive protrusion 122, and the base surface opposite to this vertex is disposed on the second side 121b of the electrode body 121. This configuration allows the pointed conductive protrusion 122 to form multiple protruding tips 122a when it contacts the charging electrode surface 210. Driven by the elastic component 130, the tips 122a effectively scrape away the dust adhering to the charging electrode surface 210, thereby ensuring that multiple points and surfaces can be well contacted between the conductive protrusion 122 and the charging electrode surface 210 to achieve stable charging.

[0050] In addition to the contact method between the electrode assembly 120 and the charging electrode surface 210, which is a "line-to-surface" or "point-to-surface" contact method made by means of the protruding teeth 1221 or the tip 122a in the above embodiments, it can also be a "surface-to-surface" contact method.

[0051] Specifically, please combine Figure 6 and Figure 7 The conductive protrusion 122 has a first surface 122b and a second surface 122c opposite to each other along the thickness direction X. The first surface 122b is connected to the second side 121b of the electrode body 121. The orthogonal projection area of ​​the second surface 122c along the thickness direction X is smaller than the orthogonal projection area of ​​the first surface 122b along the thickness direction X.

[0052] It is understandable that the projected area of ​​the second surface 122c is small. That is, when the second surface 122c and the charging electrode surface 210 are in direct contact and conduction, the contact area between them is small. The smaller contact area can increase the pressure per unit area, which helps to more effectively scrape off the dust on the charging electrode surface 210, thereby improving the conductivity between the charging electrode surface 210 and the electrode assembly 120.

[0053] exist Figures 6 to 7 In the illustrated embodiment, specifically, the conductive protrusion 122 is configured as a plurality of spaced quadrangular prisms, and the area of ​​the top surface of the prism is smaller than the area of ​​the bottom surface of the prism. In other embodiments not shown in the figures, the structure of the conductive protrusion 122 may also be configured as a frustum structure, a hemispherical structure, etc., without limitation.

[0054] like Figure 8 As shown, in another embodiment, the conductive protrusion 122 is configured as multiple sets of sequentially connected protrusions, each set of protrusions including a first protrusion 1223, a second protrusion 1224, and a third protrusion 1225 spaced apart. This configuration allows the electrode assembly to provide multiple scraping points, improving the scraping effect of the conductive protrusion 122 on dust on the charging electrode surface 210.

[0055] exist Figure 8 In the specific embodiment shown, the first protrusion 1223 and the third protrusion 1225 have the same structural shape and are symmetrically arranged about the second protrusion 1224. Thus, while ensuring aesthetics, the arrangement of multiple protrusions with different structures helps optimize the scratching effect of the conductive protrusion 122 on the surface of the charging electrode 210, and increases the contact area between the electrode assembly 120 and the charging electrode 210, thereby optimizing the charging effect.

[0056] Furthermore, please refer again. Figure 3The thickness of the electrode assembly 120 gradually decreases along its length. Specifically, the tip of the protruding tooth 1221 or the tip 122a provided on the second side 121b of the electrode body 121 can be configured such that one end is higher and the other end is lower, and its height gradually changes linearly from the higher end to the lower end. With this configuration, by designing the contact surface of the electrode assembly 120 as an inclined surface that is thicker at one end and thinner at the other end, a progressive contact mechanism is formed during the robot's alignment process, where one end contacts first and the other end contacts later. The contact surface of the electrode assembly 120 forms a leading contact area along the axial direction. At the moment of initial contact, the elastic potential energy of the elastic component 130 drives adaptive posture adjustment, thereby amplifying the axial sliding displacement of the contact surface. Under the premise of ensuring electrical connection reliability, this effectively improves the dynamic compensation capability and scraping dust removal effect of the contact interface.

[0057] For further information, please refer to [link / reference]. Figure 9 The elastic component 130 includes a first elastic element 131 and a second elastic element 132. The length of the first elastic element 131 is greater than the length of the second elastic element 132. The first elastic element 131 is connected to one end of the support component 110 and the first side 121a, and the second elastic element 132 is connected to the other end of the support component 110 and the first side 121a. Specifically, limiting grooves can be formed at both ends of the first side 121a of the electrode body 121, and limiting posts can be set at opposite positions on the support component 110. The first elastic element 131 and the second elastic element 132 are connected to the support component 110 and the electrode component 120 respectively through the limiting posts and the corresponding limiting grooves. By configuring the length parameters of the first elastic element 131 and the second elastic element 132 differently, an inclined contact surface of the electrode assembly 120 is constructed. Under the drive of the contact reaction force, the elastic element 130 triggers a progressive attitude adjustment, which transforms the initial contact impact into a deflection motion of the electrode assembly 120 along the length direction Y. Then, the conductive protrusion 122 scrapes away the accumulated dust, thereby effectively solving the problem of charging failure caused by poor contact under heavy dust conditions.

[0058] This application also provides a robot, including a robot body and a power supply device 100 as described in the above embodiments, wherein the power supply device 100 is disposed in the robot body and connected to a battery inside the robot body.

[0059] The power supply device 100, charging pile, and robot provided in this application, during the automatic charging process of the robot to the charging pile, inevitably result in a positional deviation between the robot's body electrodes and the charging pile electrodes due to the limitation of the robot's positioning device's recognition accuracy. The elastic deformation of the elastic component 130 generates an adaptive floating amount, causing dynamic sliding when the two sets of electrodes come into contact. By designing the surface of the electrode component as a convex structure, on the one hand, reducing the contact area can reduce the probability of dust blockage; on the other hand, the mechanical action during the sliding process can scrape and peel off the accumulated dust, thereby effectively solving the problem of charging failure caused by poor contact under heavy dust conditions. Furthermore, by setting the conductive protrusion 122 as a structure with one end thick and the other end thin, and by setting the length difference between the first elastic element 131 and the second elastic element 132, the electrode component 120 is in an inclined state. The deflection displacement further enhances the scraping effect of the conductive protrusion 122 on the accumulated dust, thereby more effectively solving the problem of charging failure caused by poor contact under heavy dust conditions.
