Description

Technical Field

[0001] This utility model relates to the field of intelligent robot technology, and in particular to a charging pile for charging robots. Background Technology

[0002] Existing charging stations for mobile robots are mostly installed indoors to meet heat dissipation and waterproofing requirements. Since indoor floors are flat, a simple spring mechanism is sufficient to allow for forward and backward movement of the charging head, providing some tolerance for lateral and vertical movement; no complex structure is needed. However, using this type of charging station requires users to remove the battery and bring it indoors for charging, or to bring the robot indoors for charging. This is inconvenient, and there is a risk of fire when charging lithium batteries, posing certain safety hazards for indoor charging.

[0003] Moreover, due to the limited degrees of freedom of the charging head, the alignment process between the charging pile and the robot electrode is time-consuming and labor-intensive, resulting in a low alignment rate. Even if alignment is successful, the contact area and contact pressure between the charging pile and the robot electrode after alignment do not meet the design requirements, leading to low charging efficiency, slow charging, and failure to achieve the optimal charging power.

[0004] Therefore, those skilled in the art urgently need to develop a charging station that can automatically charge outdoors with high accuracy. Summary of the Invention

[0005] The purpose of this invention is to address the technical problems existing in the background art by proposing a charging pile that allows robots to automatically charge outdoors with high accuracy in aligning with the charging pile.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A charging station includes at least: The charging pile body includes a base and a housing. The housing is disposed on the base, and the housing and the base together form a cavity. Electrical components are installed in the cavity. The cavity is provided with a channel for airflow. A base is also provided on the outside of the housing and the base. A charging head assembly is disposed on one side of the upper part of the charging pile body. The charging head assembly contains a moving component for controlling its movement. This moving component and the electrical components form a closed-loop circuit, charging the robot when the charging port is connected to it. The charging head assembly includes at least a charging port, a slider assembly for controlling the horizontal forward and backward movement of the charging port, and a charging head fixing assembly for controlling the vertical movement and horizontal rotation of the charging port. The charging head fixing assembly is provided with electrical limit switches for controlling the rotation of the charging port around the X-axis and controlling the rotation of the charging port around the Y-axis. The slider assembly and the charging head fixing assembly are movably connected as one unit.

[0007] In one embodiment, the electrical limit switch assembly includes electrodes, an electrode rotation shaft, and two limiting wheels. The two limiting wheels are disposed below the charging head fixing assembly and are movably connected as a single unit via a limiting wheel shaft. Two electrodes are disposed on both sides of the charging head fixing assembly and are connected via an electrode rotation shaft passing through the charging head fixing assembly. The assembly also includes a second tension spring, one end of which is connected to the end of the electrode, and the other end of which is connected to the bottom of the charging head fixing assembly.

[0008] In one embodiment, a limit spring is provided at the rear of the limit wheel axle.

[0009] In one embodiment, an electrode compression spring is provided at the rear of the electrode rotation shaft.

[0010] In one embodiment, the charging head fixing assembly and the bearing fixing member are connected as one unit by a bearing with a seat; it also includes two third tension springs, which are respectively disposed on both sides of the bearing fixing member, one end of the third tension spring is disposed on one side of the bearing fixing member, and the other end of the third tension spring is disposed on one end of the charging head fixing member.

[0011] In one embodiment, the bearing fixing member includes a bearing and a guide rod disposed inside the bearing and cooperating with the bearing. A first tension spring is provided on the bearing fixing member, one end of the first tension spring is connected to the slider assembly, and the other end of the first tension spring is fixedly connected to the bearing fixing member.

[0012] In one embodiment, the guide rod is provided with a groove, and the bearing fixing member is provided with a limiting washer for limiting the rotation angle of the guide rod.

[0013] In one embodiment, the housing includes at least an electrical compartment, a rear top cover, and a front top cover. Electrical components are disposed within the electrical compartment. The rear top cover is fixedly connected to the electrical compartment and is provided with dustproof and waterproof material. The front top cover is disposed above the charging port, and the front top cover and the rear top cover are fixedly connected as a single unit.

[0014] In one embodiment, the front top cover is a split structure, which is fixed together as one unit by fasteners; the rear top cover is a split structure, which is fixed together as one unit by fasteners.

[0015] In one embodiment, the slider assembly includes a nitrogen spring, a guide rail, and a sliding component. The guide rail and the nitrogen spring are fixedly disposed at the bottom of the front top cover. One end of the sliding component is fixedly disposed on the guide rod, and the other end of the sliding component is connected to the nitrogen spring, and the nitrogen spring can slide relative to the guide rail.

[0016] In one embodiment, a fan is also provided, and the cold air at the bottom is driven by the fan to be discharged from the underside of the front top cover through the electrical compartment.

[0017] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: Due to the above-mentioned structural design of the charging pile of this utility model, the structure allows the entire charging head to have a downward tolerance of about (Z-)45mm, a rotation angle of about ±15° on the (Z-axis), a small rotation angle of about ±5° on the (Y) axis of the entire charging electrode assembly, a small swing angle and a small forward and backward extension distance on the (X) axis of the charging head, plus two limiting wheels, which can ensure that the robot and the electrode assembly of the charging pile are initially aligned on the same horizontal line, thereby greatly improving the accuracy of the vehicle alignment process, and avoiding the influence of external factors such as manufacturing errors, ground errors or inconsistent tire pressure on the alignment accuracy.

[0018] The above-mentioned structural design of this utility model can effectively protect the charging process from external environmental factors because the top cover of the charging pile can protect the bottom during the charging process, and the rubber on the side of the charging head can protect the left and right sides. This solves the problem that the charging pile cannot be charged outdoors.

[0019] This utility model's charging pile is designed with a specific airflow direction within its structure. Air enters through two fans at the bottom, flows through the electrical compartment to the front top cover, and then exits from the lower front side of the top cover. In other words, cooler air enters from the bottom, becomes warmer as it passes the heating elements, and exits from the top. Since the exhaust side is part of the charging head, the hot air also carries away moisture from the charging head, keeping it dry. Attached Figure Description

[0034] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] The embodiments of this utility model will be further described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described herein are merely exemplary. The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0036] like Figures 1 to 14 As shown, this utility model provides a charging pile, including a charging pile body and a charging head assembly 6. The charging pile body includes a base and a housing, with the housing disposed on the base. The housing and the base together form a cavity, and electrical components are installed within the cavity. The cavity has a channel for airflow. Figure 1 As shown, a base 2 is also provided on the outside of the shell. In order to facilitate the fixing of the base to the ground, a support foot is provided at the bottom of the base. The base 2 further strengthens the connection between the shell and the base.

[0037] Specifically, the housing includes at least an electrical compartment 1, a rear top cover 3, and a front top cover 5. Electrical components are housed inside the electrical compartment 1. The rear top cover 3 is fixedly connected to the electrical compartment 1 and is provided with dustproof and waterproof material. The front top cover 5 is located above the charging port and is fixedly connected to the rear top cover 3 as a whole.

[0038] To facilitate installation and manufacturing, the rear top cover 3 is fixedly connected to the electrical compartment 1 by bolts, and sealing foam is installed between the rear top cover 3 and the compartment 1 to ensure that the compartment 1 is dustproof and waterproof. The front top cover 5 is fixedly connected to the compartment by bolts.

[0039] Furthermore, the front top cover 5 is designed as a separate structure, which is fixed together as a single unit using fasteners. The rear top cover 3 is also designed as a separate structure, which is fixed together as a single unit using fasteners. This separate structural design simplifies the product manufacturing process, saves transportation costs, and improves economic efficiency.

[0040] The charging head assembly 6 is located on one side of the upper part of the charging pile body. The charging head assembly 6 has a moving part for controlling the movement of the charging head assembly. The moving part and the electrical components form a closed loop circuit. When the charging port is connected to the robot 32, the robot is charged.

[0041] Specifically, the charging head assembly 6 includes at least a charging port, a slider assembly 12 for controlling the horizontal forward and backward movement of the charging port, and a bearing fixing member 17 for controlling the vertical movement and horizontal rotation of the charging port. The charging head fixing assembly 19 is provided with an electric limit position assembly for controlling the rotation of the charging port around the Y-axis and controlling the rotation of the charging port around the X-axis.

[0042] In this embodiment, the slider assembly 12 and the charging head fixing assembly 19 are movably connected as a whole via the bearing fixing member 17. The charging head fixing assembly 19 and the bearing fixing member 17 are rotatably connected as a whole.

[0043] like Figure 2As shown, the electric limit switch assembly includes an electrode 20, an electrode rotation shaft 21, and two limit wheels 23. The two limit wheels are located below the charging head fixing assembly 19, and the two limit wheels 23 are movably connected as one unit via a limit wheel shaft 22. A limit spring 24 is provided at the rear of the limit wheel shaft 22, allowing it to move backward a certain distance to improve the stability of the pile driving process.

[0044] Two electrodes 20 are disposed on both sides of the charging head fixing assembly 19. The two electrodes 20 are connected by an electrode rotation shaft 21 passing through the charging head fixing assembly 19, and can each rotate independently around the left and right X-axis of the charging head fixing assembly 19. An electrode compression spring 25 is placed at the rear end so that it can move backward a certain distance.

[0045] The electrical limit switch assembly also includes a second tension spring 16. One end of the second tension spring 16 is connected to the end of the electrode 20, and the other end is connected to the bottom of the charging head fixing assembly 19. This connection method can provide the electrode 20 with an initial small upward tilt angle, which is convenient for alignment. Figure 3 As shown, an electrode compression spring 25 is provided at the rear of the electrode rotation shaft 21.

[0046] like Figure 2 As shown, the charging head fixing assembly 19 and the bearing fixing member 17 are connected as one unit by a bearing with a mounting seat, and can rotate along the front and rear Y-axis. Third tension springs 18 are arranged on both sides to facilitate the return of the charging head fixing assembly 19 after rotation. Two third tension springs 18 are also included, respectively disposed on both sides of the bearing fixing member 17. One end of the third tension spring 18 is disposed on one side of the bearing fixing member 17, and the other end of the third tension spring 18 is disposed on one end of the charging head fixing member 19.

[0047] Two limiting posts 28 are provided on the top of the charging head fixing assembly 19 to limit its rotation angle around the Y axis.

[0048] like Figure 4 As shown, the bearing fixing component 17 includes a bearing 14 and a guide rod 15 disposed within the bearing 14 and cooperating with the bearing. A first tension spring 13 is provided on the bearing fixing component. One end of the first tension spring 13 is connected to the slider assembly 12, and the other end of the first tension spring 13 is fixedly connected to the bearing fixing component 17. In this embodiment, the bearing 14 used is a linear bearing.

[0049] The first tension spring 13 is mainly used to limit the up-and-down movement and left-and-right rotation of the bearing fixing part 17. When rotating left and right, the rotation direction can be limited by the limiting washer 26 and the groove of the guide rod 15 to prevent the rotation angle from being too large and thus unable to return to the original position. The guide rod 15 is provided with a groove, and the bearing fixing part 17 is provided with a limiting shim for limiting the rotation angle of the guide rod 15.

[0050] like Figure 2 and Figure 5 As shown, the slider assembly 12 includes a nitrogen spring 10, a guide rail 11, and a sliding component 12. The guide rail 11 and the nitrogen spring 10 are fixedly mounted on the bottom of the front top cover 5. One end of the sliding component 12 is fixedly mounted on the guide rod 15, and the other end of the sliding component 12 is connected to the nitrogen spring 10, which can slide relative to the guide rail 11. When the sliding component 12 moves backward, the nitrogen spring 10 can provide rated damping to limit its sliding.

[0051] like Figure 1 As shown, multiple fans 4 are also installed on the casing. The arrangement of the fans 4 creates a channel for airflow inside the charging pile, such as... Figure 14 As shown, the entire charging station draws in air through two fans 4 at the bottom, flows through the electrical compartment 1 to the front top cover 5, and then exits from the lower front side of the front top cover 5. In other words, the cooler air enters from the bottom, becomes warmer as it passes the heating elements, and exits from the top. Since the exhaust side is part of the charging head, the hot air also carries away moisture from the charging head, keeping it dry.

[0052] As shown in Figure 6, the side of the charging head of this utility model is also provided with rubber 33. The rubber on the side of the charging head can protect the left and right sides and can effectively protect the charging process from the influence of external environmental factors (such as weather).

[0053] The specific applications of this utility model are as follows: When aligning the stakes, if Figure 4 As shown, robot 32 identifies charging station 31 and moves towards the charging station, as... Figure 7 As shown, the upper part of the V-shaped groove at the tail of robot 31 first contacts the two limiting wheels 23 of the charging head fixing assembly 19. During this process, assume that the direction of movement of robot 32 has a certain angular deviation from the horizontal direction of charging pile 31, such as... Figure 8 and Figure 9 As shown, the charging head fixing assembly 19 is passively rotated around the guide rod 15 until the limiting wheel 23 moves into the V-shaped groove.

[0054] If the direction of movement of robot 32 deviates from that of charging station 31 by a certain angle in the vertical direction, such as Figure 12 and Figure 13 As shown, the charging head electrode 20 rotates around the electrode rotation axis 21 until the limiting wheel moves into the V-shaped groove. The two limiting wheels move backward and downward with the robot 32, and the entire charging head fixing assembly 19 gradually conforms to the V-shaped groove as the robot moves. Figure 12 As shown, the robot continues to move backward until the limit wheel 23 moves to the position shown. Figure 13 The limiting wheel 23 stops moving only in the middle of the V-shaped groove shown.

[0055] After the limiting wheel 23 moves to the center of the robot's V-shaped groove, the robot continues to move backward. The electrode plate 35 at the tail of the robot contacts the electrode 20 of the charging head assembly. The electrode 20 moves back and forth and rotates a small angle around the left and right X-axis to fit the robot's electrode plate. At the same time, the entire charging head fixing assembly 19 moves backward a certain distance along the sliding assembly 12. When the electrode plate 35 is fully in contact, the proximity switch 34 detects the signal and issues a command, the robot stops moving and begins automatic charging.

[0056] The charging pile structure design of this utility model allows for a downward (Z-) tolerance of approximately 45mm for the entire charging head, a rotation angle error of approximately ±15° on the (Z-axis), a small rotation angle of approximately ±5° on the (Y) axis of the entire charging electrode assembly, a small swing angle and a small forward and backward extension distance on the (X) axis of the charging head, and two limiting wheels. This design ensures that the robot and the electrode assembly of the charging pile are initially aligned on the same horizontal line, thereby greatly improving the accuracy of the vehicle alignment process and avoiding the impact of external factors such as manufacturing errors, ground errors, or inconsistent tire pressure on the alignment accuracy.

[0057] In the structural design of this utility model, the top cover of the charging pile can protect the charging head assembly below during the charging process, and the rubber on the side of the charging head can protect the left and right sides. The interaction can effectively protect the charging process from external environmental factors, thereby solving the problem that the charging pile cannot be charged outdoors.

[0058] This utility model's charging pile is designed with a specific airflow direction within its structure. Air enters through two fans at the bottom, flows through the electrical compartment to the front top cover, and then exits from the lower front side of the top cover. In other words, cooler air enters from the bottom, becomes warmer as it passes the heating elements, and exits from the top. Since the exhaust side is part of the charging head, the hot air also carries away moisture from the charging head, keeping it dry.

[0059] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
