Description

Technical Field

[0001] This utility model relates to the field of unmanned inspection robot technology, specifically to a wired charging device and system for a quadruped robot. Background Technology

[0002] The increasing demand for unmanned inspection systems in remote areas has led to the widespread adoption of quadruped robots in various scenarios. Due to the need for unmanned inspection across all scenarios, the charging and recharging systems for these robots also need to meet the requirements of stability, reliability, and ease of maintenance. Currently, two solutions exist: wireless charging and wired charging. Wireless charging reduces direct contact between the battery and the charging system, minimizing system wear; however, it suffers from low charging efficiency, high heat generation, and low reliability. Wired charging offers faster charging efficiency and higher reliability, making it the preferred choice for unmanned quadruped robot recharging. However, wired charging requires high precision in positioning between the quadruped robot and the charging base. The quadruped robot must maintain reliable contact with the charging base during charging, and the charging base must be easy to operate and maintain. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0028] Example 1

[0029] This embodiment provides a wired charging device for a quadruped robot, such as... Figure 1 As shown, it includes: a charging base 1 and a positioning cylindrical assembly 2;

[0030] The charging base 1 includes a base body, a positive electrode post 11, a negative electrode post 14, and a support post 12.

[0031] The positive electrode post 11, negative electrode post 14, and support post 12 are all disposed on the upper surface of the base body, and the planes of the electrode connecting post and the negative electrode post 14 are perpendicular to the plane of the support post 12. The positive electrode post 11 and the negative electrode post 14 charge the battery module 33 by contacting the charging electrode 331. The positive electrode post 11 and the negative electrode post 14 are both capable of extending and retracting relative to the base body.

[0032] like Figure 2 As shown, the charging base 1 includes a base shell and a cavity. The positive electrode post 11 and the negative electrode post 14 are vertically fixed to the upper part of the charging base 1 by screws. Their bottoms are made of insulating material to achieve insulation from the base shell. The screw fixing facilitates disassembly, improving the convenience of later maintenance of the consumable components, the positive electrode post 11 and the negative electrode post 14. Simultaneously, the positive electrode post 11 and the negative electrode post 14 are designed in a flexible and retractable mode, facilitating their use in conjunction with the support post 12 to reliably support the quadruped robot 3. The support post 12 is vertically fixed to the upper part of the charging base 1 by screws and is electrically connected to the base shell. Its height is lower than that of the positive electrode post 11 and the negative electrode post 14, preventing poor contact between the positive electrode post 11 and the negative electrode post 14 and the battery module 33 below the quadruped robot 3. The AC / DC converter 13 is mounted inside the charging base 1 via support post 12 studs. The AC / DC converter 13 includes one input interface and two output interfaces, namely a battery charging output interface and a 12V DC output interface. The input interface is connected to the external input interface of the charging base 1 via a cable to realize external power supply. The battery charging output interface of the AC / DC converter is connected to the positive electrode post 11 and the negative electrode post 14 of the charging area above the charging base 1 via a cable and cable connection terminal to charge the battery module 33. The 12V DC output interface is connected to the green charging indicator light on the front of the charging base 1 via a cable and cable connection terminal to provide a charging indicator light while charging the battery module 33.

[0033] like Figure 3 As shown, the quadruped robot 3 includes a body 31, four legs 32, a battery module 33, and a visual recognition system 34. The four legs are symmetrically arranged on both sides of the body 31, enabling it to walk through various scenarios. The battery module 33 is located inside the body 31, and a charging electrode 331 is located at the bottom of the body 31 and connected to the battery module 33. The visual recognition system 34 is located at one end of the body 31. In this embodiment, the visual recognition system 34 includes a high-definition camera. The quadruped robot 3 uses the high-definition camera to identify and locate the position of the cylindrical component 2, thereby accurately sitting on the charging base 1, ensuring that the charging electrode 331 at the bottom of the battery module 33 is correspondingly connected to the positive electrode post 11 and the negative electrode post 14 on the charging base 1.

[0034] like Figure 1 As shown, the positioning cylinder assembly 2 includes two cylinders coated with patterns that are easily recognized by the visual recognition system 34. They are placed vertically and symmetrically behind the charging base 1. The quadruped robot 3 recognizes the patterns through a high-definition camera, thereby achieving precise positioning.

[0035] like Figure 4 As shown, in this embodiment, the battery module 33 has two planar circular metal electrodes at the bottom, which are used to electrically connect with the positive electrode post 11 and the negative electrode post 14 on the charging base 1 to charge and replenish the battery module 33.
