Abstract
Description
Technical Field
[0001] The utility model relates to the photovoltaic field, in particular to an automatic charging system. Background Art
[0002] Currently, on-board cleaning robots charge in hangars using manual charging stations. However, these stations require manual plugging and unplugging, which contradicts the unmanned, intelligent design objectives of the on-board cleaning robots. This wastes human resources and even creates the risk of the robot becoming inoperable due to forgetting to charge. There are two main types of automatic charging stations currently used by on-board cleaning robots on the market: one leaves both the on-board charging electrodes and the charging station electrodes exposed, facilitating docking; the other leaves the charging station electrodes exposed, while the on-board charging electrodes are placed in an on-board charging box. The door panels of the on-board charging box are controlled by a motor or push rod, preventing the on-board charging electrodes from being exposed. The first type of automatic charging station leaves the on-board charging electrodes exposed, creating the risk of damage or moisture leading to a short circuit. The other type of automatic charging station requires a separate control to open and close the on-board charging box, resulting in a more complex structure, higher costs, and the risk of control failure resulting in unsafe and effective charging.

[0033] Please refer to Figures 1 to 15 As shown, the present invention discloses an automatic charging system, including an automatic charging pile 100 and an on-board charging box 200. The automatic charging pile 100 includes an electrode protection cover 101, a charging pile electrode 102 and a door top block 103. The electrode protection cover 101 covers the charging pile electrode 102 and has an opening 1010 in front of the electrode protection cover 101. The door top block 103 is arranged on the electrode protection cover 101 near the opening 1010. The on-board charging box 200 includes a charging box body 201, a charging box electrode 202 and a blocking door plate 203. The charging box electrode 202 is located in the charging box body 201, and the blocking door plate 203 is shielded on one side of the charging box body 201. When the door top block 103 pushes open the blocking door plate 203 and the charging pile electrode 102 is connected to the charging box electrode 202, the automatic charging pile 100 starts charging the on-board charging box 200. The electrode protection cover 101 of the present invention covers the charging pile electrode 102 and the blocking door panel 203 is blocked on one side of the charging box body 201. The present invention protects the electrodes at both the robot end and the charging pile end; when the door opening top block 103 pushes open the blocking door panel 203 and the charging pile electrode 102 is connected to the charging box electrode 202, the automatic charging pile 100 starts to charge the vehicle-mounted charging box 200, thereby making automatic charging safe and reliable.
[0034] Please refer to Figures 6 to 8As shown, the automatic charging pile 100 also includes a charging pile base 104. An electrode protection cover 101 and a charging pile electrode 102 are disposed on the charging pile base 104. The electrode protection cover 101 is retractable relative to the charging pile base 104. The electrode protection cover 101 extends forward so that the charging pile electrode 102 is located within the electrode protection cover 101, and retracts backward so that the charging pile electrode 102 is exposed outside the electrode protection cover 101. The retractable nature of the electrode protection cover 101 relative to the charging pile base 104 ensures that it extends in the non-charging state to protect the charging pile electrode 102 and retracts in the charging state to expose the charging pile electrode 102 for charging.
[0035] Please refer to Figures 6 to 12 As shown, the automatic charging pile 100 also includes an electrode shield connecting rail 105. The electrode shield connecting rail 105 includes a first linear bearing seat 1051, a first guide shaft 1052, a first compression spring 1053, and a first guide clamp 1054. The first linear bearing seat 1051 is mounted on the charging pile base 104. One end of the first guide shaft 1052 passes through the first linear bearing seat 1051 and the first compression spring 1053 and is connected to the electrode shield 101. The other end of the first guide shaft 1052 is connected to the first guide clamp 1054, so that the first compression spring 1053 presses the first linear bearing seat 1051 and the electrode shield 101. The function of the electrode shield connecting rail 105 is to flexibly connect the electrode shield 101 to the charging pile base 104.
[0036] Please refer to Figures 6 to 15 As shown, the automatic charging pile 100 also includes an electrode connection rail 106 and an electrode swing device 107. The electrode connection rail 106 includes a second linear bearing seat 1061, a second guide shaft 1062, a second compression spring 1063, and a second guide clamp 1064. The second linear bearing seat 1061 is mounted on the charging pile base 104. One end of the second guide shaft 1062 passes through the second linear bearing seat 1061 and the second compression spring 1063 and is connected to the electrode swing device 107. The other end of the second guide shaft 1062 is connected to the second guide clamp 1064, so that the second compression spring 1063 presses the second linear bearing seat 1061 and the electrode swing device 107. The function of the electrode connection rail 106 is to flexibly connect the electrode swing device 107 to the charging pile base 104.
[0037] Please refer to Figure 6 、 Figures 13 to 15As shown, the electrode oscillating device 107 includes a pin 1071, a spherical bearing 1072, a male lug plate 1073, a female lug plate 1074, and a baffle 1075. One end of the electrode oscillating device 107 is connected to the second guide shaft 1062, and the other end of the electrode oscillating device 107 is connected to the charging pile electrode 102 via the pin 1071. The male lug plate 1073 includes a base 10731 and two plates 10732 extending in the same direction and parallel from opposite sides of the base 10731. The female lug plate 1074 is a single piece and is inserted between the two plates 10732. The pin 1071 extends vertically through the male lug plate 1073 and the female lug plate 1074. The joint bearing 1072 is arranged between the pin 1071 and the male ear plate 1073, so that the charging pile electrode 102 can achieve a certain degree of up and down swing; the baffle 1075 is arranged on both sides of the female ear plate 1074, so that the charging pile electrode 102 can achieve a certain degree of left and right swing. An elastic element (not shown) is connected between the electrode swing device 107 and the charging pile electrode 102, which is used to reset the charging pile electrode 102 after swinging. The reserved swing amount in the up and down directions and the left and right directions is to ensure that when the charging box electrode 202 on the vehicle-mounted charging box 200 and the charging pile electrode 102 on the automatic charging pile 100 have a certain angle, the angle tolerance is eliminated by rotating the charging pile electrode 102 on the automatic charging pile 100, so that the charging pile electrode 102 and the charging box electrode 202 can fit better, thereby ensuring the charging effect.
[0038] Please refer to Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, the charging pile electrode 102 includes a network signal electrode 1021 and a charging electrode 1022 (correspondingly, the charging box electrode 202 also includes another network signal electrode 2021 and another charging electrode 2022). There are two electrode connecting rails 106, and the two electrode connecting rails 106 correspond to driving the network signal electrode 1021 and the charging electrode 1022 respectively. There is one electrode protection cover connecting rail 105, and it drives the electrode protection cover 101. The extension amount of the three sets of rails is different, among which the extension amount of the electrode protection cover 101 is the largest, and the electrode protection cover 101 is fully retracted. The state extends a distance further than the network signal electrode 1021 (for example, 20mm). The network signal electrode 1021 extends another distance further than the charging electrode 1022 (for example, 30mm). The purpose is to ensure that the electrode protection cover 101 can always protect the charging pile electrode 102 and is used to push up the blocking door panel 203 of the on-board charging box 200.
[0039] Please refer to Figure 4 and Figure 5As shown, door suction cups 204 are provided on opposite sides of the charging box housing 201, and a torsion spring hinge 205 providing a torsional force is provided on the blocking door panel 203. The door suction cups 204 ensure that the blocking door panel 203 is in a closed state when not charging. The purpose of providing the torsion spring hinge 205 is to enable the blocking door panel 203 to switch between an open state and a closed state. In other words, the torsion spring hinge 205 provides a torsional force to the blocking door panel 203 between the open state and the closed state.
[0040] Please refer to Figure 4 and Figure 5 As shown, the blocking door panel 203 includes two pieces and is either a vertically split type or a horizontally split type. In a specific embodiment, the blocking door panel 203 is a vertically split type. Of course, in other embodiments, a single blocking door panel 203 can be opened in the upper / lower / left / right direction.
[0041] Please refer to Figure 4 As shown, an anti-collision pad 206 is provided on the outer surface of the blocking door panel 203 . When the blocking door panel 203 is pushed open, the anti-collision pad 206 contacts the blocking door panel 203 to protect the blocking door panel 203 .
[0042] Please continue to refer to Figure 4 As shown, a brush 207 is provided in the middle of the blocking door plate 203. When the blocking door plate 203 is pushed open, the brush 207 flexibly contacts the charging box electrode 202 to reduce the design depth of the charging box body 201.
[0043] The specific operation process of the present invention is as follows: as the robot 300 drives toward the automatic charging pile 100, after the door opening top block 103 on the electrode protection cover 101 pushes against the blocking door panel 203 of the onboard charging box 200, as the electrode protection cover 101 continues to move deeper, the blocking door panel 203 is fully opened, and eventually the door opening top block 103 of the electrode protection cover 101 will push against the deepest plate of the charging box body 201. As the robot 300 continues to move backward, the compression spring behind the electrode protection cover 101 is continuously compressed. When another network signal electrode 2021 located on the raised panel inside the charging box body 201 is connected to the network signal electrode 1021 on the automatic charging pile 100, CAN communication between the automatic charging pile 100 and the onboard charging box 200 is established, and the automatic charging pile 100 begins to prepare for charging. As the robot 300 continues to move backward, the compression spring behind the electrode shield 101 continues to compress, and the compression spring behind the network signal electrode 1021 on the automatic charging pile 100 also begins to compress. When the other charging electrode 2022 located on the raised panel inside the charging box body 201 connects with the charging electrode 1022 on the automatic charging pile 100, the automatic charging pile 100 begins to charge the vehicle-mounted charging box 200. At this time, the robot 300 stops moving backward and waits for charging to complete. After charging is complete, as the robot 300 moves forward, the charging electrode 1022, network signal electrode 1021, and electrode shield 101 on the automatic charging pile 100 successively break away from contact with the other charging electrode 2022 in the vehicle-mounted charging box 200, the other network signal electrode 2021, and the deepest plate of the charging box body 201. As the robot 300 continues to move forward, the electrode protection cover 101 detaches from the vehicle-mounted charging box 200. Under the action of the torsion spring hinge 205, the blocking door panel 203 of the vehicle-mounted charging box 200 automatically closes, thereby achieving sealed protection for the charging box electrode 202 in the vehicle-mounted charging box 200.
[0044] To sum up, the electrode protection cover 101 can cover the charging pile electrode 102 and block the blocking door plate 203 on one side of the charging box body 201. The utility model protects the electrodes on both the robot end and the charging pile end; when the door opening top block 103 pushes open the blocking door plate 203 and the charging pile electrode 102 is connected to the charging box electrode 202, the automatic charging pile 100 starts to charge the vehicle-mounted charging box 200. The automatic charging process of the automatic charging system of the utility model is safe and reliable.

The understanding of the present invention should be based on technical personnel in the relevant technical field. Although this specification has described the present invention in detail with reference to the above embodiments, ordinary technical personnel in the field should understand that technical personnel in the relevant technical field can still modify or replace the present invention with equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
