Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] This embodiment provides a convenient charging structure for a robot, as shown in the attached diagram. Figure 1 and 3 The system includes a base 1, a battery cell 6, a positioning head 5, and a pressure plate 3. The top of the base 1 is connected to the bottom of the robot 20. The positioning head 5 is located at the bottom of the base 1 and has a through-hole in the positioning head 5. The battery cell 6 is located in the mounting cavity. The pressure plate 3 is located above the base 1 and its bottom is in contact with the top of the battery cell 6. The pressure plate 3 has a wire hole 31 that is opposite to the top of the battery cell 6. The outer side of the bottom end of the positioning head 5 has an arc surface.

[0022] The charging structure of this invention is mounted on the bottom of the robot 20 via a base 1. During use, the robot 20 autonomously moves the charging structure to the charging device and automatically docks, enabling convenient charging without manual intervention, thus improving charging convenience and flexibility. A positioning head 5 guides and positions the charging structure when docking with the charging port of the charging device. The battery cell 6 is embedded in the positioning head 5 at the bottom of the base 1 and is attached to the top of the battery cell 6 by a pressure plate 3, thus protecting the battery cell 6 from external impacts and damage, improving the safety of the charging process. An arc surface is provided on the outer bottom of the positioning head 5 for automatic alignment guidance when the charging structure docks with the charging port of the robot 20, achieving position calibration. The pressure plate 3 has a wire hole 31, allowing the robot 20's charging cable to pass through the wire hole 31 and connect to the battery cell 6.

[0023] Preferred options are listed in the appendix. Figure 2It also includes an insulating sleeve 7, which is fitted over the outside of the battery cell 6 and located inside the mounting cavity. By fitting the insulating sleeve 7 over the outside of the battery cell 6, the insulating sleeve 7 is positioned between the battery cell 6 and the positioning head 5, isolating the battery cell 6 from direct contact with the inner wall of the mounting cavity of the positioning head 5. This avoids safety hazards caused by leakage or short circuit of the battery cell 6, improves charging safety, and reduces the risk of failure. In addition, the insulating sleeve 7 also acts as a buffer, cushioning vibrations or friction generated during operation, preventing the battery cell 6 from being subjected to vibration or impact, and extending the service life of the battery cell 6.

[0024] Preferably, an insulating pad 8 is also included, which is disposed between the pressure plate 3 and the battery cell 6. By providing the insulating pad 8, after the battery cell 6 is installed, both ends of the insulating pad 8 abut against the pressure plate 3 and the top of the battery cell 6, respectively. The elastic deformation of the insulating pad 8 fills the gap between the pressure plate 3 and the battery cell 6, preventing excessive pressure on the battery cell 6 during installation and thus avoiding damage. It also prevents the battery cell 6 from shaking or shifting during robot 20 movement or operation, thereby improving the overall structural stability. Furthermore, the insulating pad 8 also isolates the battery cell 6 from direct contact with the pressure plate 3, preventing safety hazards caused by leakage or short circuits in the battery cell 6, improving charging safety, and reducing the risk of failure.

[0025] Preferably, the device also includes a first fastening screw 41, which is threadedly connected to the pressure plate 3 and the base 1, with its bottom end extending below the base 1. By setting the first fastening screw 41, the pressure plate 3 and the base 1 are connected, thereby fixing the battery cell 6. The tightness of the first fastening screw 41 can be adjusted to regulate the clamping force of the pressure plate 3 on the battery cell 6, ensuring the battery cell 6 is fixed while preventing excessive clamping force from damaging it, thus improving the service life of the battery cell 6. Using the threaded connection of the first fastening screw 41 for fixing makes the installation and removal of the pressure plate 3 and the battery cell 6 more convenient, facilitating the replacement of the battery cell 6 and reducing maintenance complexity.

[0026] Preferably, the system also includes a vision camera 2, a camera bracket 9, and a second fastening screw 4. The vision camera 2 is mounted on the camera bracket 9, and the camera bracket 9 is fixed to both sides of the base 1 by the second fastening screw 4. The vision camera 2 is fixed to both sides of the base 1 by the second fastening screw 4 and the camera bracket 9, and the lens of the vision camera 2 is tilted downwards. This ensures that after the charging structure is installed at the bottom of the robot 20, the vision camera 2 is located on the front and rear sides of the robot 20. By acquiring real-time images of the front and rear sides of the robot 20 through the vision camera 2, the robot 20 can automatically drive the charging structure to connect with the charging port of the charging device.

[0027] Preferably, the mounting cavity includes a first limiting hole 511 and a second limiting hole 512 connected vertically, with the inner diameter of the first limiting hole 511 being larger than that of the second limiting hole 512. By providing the first limiting hole 511 and the second limiting hole 512 connected vertically, the mounting cavity matches the external structure of the battery cell 6, thereby accommodating the battery cell 6; and the inner diameter of the first limiting hole 511 being larger than that of the second limiting hole 512, thereby limiting the battery cell 6. The pressure plate 3 and the second limiting hole 512 respectively limit the upper and lower dimensions of the battery cell 6, preventing axial movement of the battery cell 6.

[0028] Preferably, the base 1 has a third limiting hole 11 and a first positioning groove 12. The first positioning groove 12 is located on the outer periphery of the top of the third limiting hole 11. The positioning head 5 has a limiting ring 52 extending outward. The positioning head 5 is located inside the third limiting hole 11. The limiting ring 52 cooperates with the first positioning groove 12, so that the bottom end of the positioning head 5 passes through the third limiting hole 11 and extends to the bottom of the base 1. Through the cooperation of the limiting ring 52 and the first positioning groove 12, the positioning head 5 is installed on the base 1, so that the outer side of the positioning head 5 fits with the third limiting hole 11, and the bottom of the positioning head 5 extends to the bottom of the base 1, so that the positioning head 5 plays a docking and guiding role. The cooperation of the limiting ring 52 and the first positioning groove 12 can effectively limit the radial and axial movement of the positioning head 5, prevent the positioning head 5 from shaking or shifting during installation, and fix the positioning head 5 to the base 1 by the pressure plate 3, thereby improving the stability and reliability of the overall structure.

[0029] Preferably, the bottom of the pressure plate 3 has a second positioning groove 32, which is located on the outer periphery of the bottom end of the wire hole 31. The insulating pad 8 is disposed in the second positioning groove 32, with its bottom end in contact with the battery cell 6 and its top end in contact with the inner side of the wire hole 31. A through hole connected to the wire hole 31 is provided in the middle of the insulating pad 8. By providing the second positioning groove 32 at the bottom of the pressure plate 3 to accommodate the insulating pad 8, the two ends of the insulating pad 8 are respectively in contact with the pressure plate 3 and the battery cell 6 after the pressure plate 3 is installed. The elastic deformation of the insulating pad 8 is used to press the battery cell 6.

[0030] Preferably, the base 1 has multiple hollow sections 13, which are distributed on the outer side of the mounting cavity. By creating hollow sections 13 on the base 1, the overall weight of the base 1 is reduced, saving materials. Furthermore, the hollow sections 13 also serve a certain heat dissipation function, preventing overheating during charging.
