For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0035] As shown in the figure, a modular host structure of a quadruped robot includes: a host lower shell 1, having a base plate 110 and a ring plate 120 erected from the edge of the base plate 110, the base plate 110 and the ring plate 120 forming a cavity; the base plate 110 is provided with a plurality of clamping platforms 111 along the opening direction of the cavity, the base plate 110 is provided with a first notch 112 at two adjacent top corners of the base plate 110, a first fixing portion 113 is provided adjacent to the first notch 112, the first fixing portion 113 is connected to the circuit interface 3, the base plate 110 is also provided with a second fixing portion 114, the second fixing portion 114 is connected to the battery interface 4; the ring plate 120 is provided with a plurality of inwardly concave first grooves 121, the first grooves 121 are annular grooves, the host upper shell 2, the edge of the host upper shell 2 matches the edge of the ring plate 120 to close the cavity, the host upper shell 2 is provided with a plurality of bosses, the bosses are clamped with the clamping platforms 111, and the positions of the bosses correspond one to one with the positions of the clamping platforms 111.

[0036] Specifically, since the bottom plate 110 and the ring plate 120 of the mainframe lower shell 1 form a cavity, the cavity is used to accommodate components such as the mainboard, and the mainframe upper shell 2 covers the cavity. Figure 5As shown, the mainframe lower shell 1 is provided with studs to fix the mainboard 9 and the power board 10. The clamping platform 111 of the mainframe lower shell 1 is clamped with the boss of the mainframe upper shell 2. The mainframe lower shell 1 and the mainframe upper shell 2 are provided with fixing holes. The mainframe lower shell 1 and the mainframe upper shell 2 are connected by fasteners to form a modular mainframe structure, ensuring that the circuit board is protected from external impact, vibration and electromagnetic interference, making the components in the sealed cavity waterproof and dustproof, improving the stability and reliability of the quadruped robot's operation, and waterproofing, etc., and better meeting the customer's usage needs in different scenarios. In addition, the modular design makes it more convenient and quick to replace and repair parts, which can significantly reduce maintenance costs; due to the large amount of interchangeability between modules, after-sales service costs can be reduced.

[0037] The first notch 112 of the mainframe lower shell 1 is reserved for mounting the robot's motion module. The first fixing portion 113 is used to connect the motion module's electrical wiring. The second fixing portion 114 of the mainframe lower shell 1 is used to connect to the battery. The annular groove in the mainframe lower shell 1 is reserved for mounting the robot's body shell. The modular mainframe structure defines the mounting locations of various components, improving the machine's performance.

[0038] In this embodiment, the base plate 110 and the ring plate 120 are integrally formed. Thanks to advances in current manufacturing technology, the main unit lower housing 1, whether constructed from metal or injection-molded components, can be integrally formed. This one-piece molding process significantly simplifies the production process by eliminating component disassembly during the design process and directly eliminating the need for component assembly. This not only shortens the product's production cycle but also improves the integrity and reliability of the main unit lower housing 1, reducing potential errors and failures during the assembly process, and significantly enhancing the dimensional and shape accuracy of the main unit lower housing 1.

[0039] In order to further meet the use scenarios of the modular host structure, in this embodiment, the first fixing portion 113 is a through groove opened in the bottom plate 110, and the second fixing portion 114 is a second groove sunken in the bottom plate 110 along the opening direction of the cavity. The second groove is provided with a through hole 115 that matches the battery interface 4. The circuit interface 3 is embedded in the through groove; the battery interface 4 is a pin type, and the pin of the battery interface 4 is inserted into the through hole 115. In addition, Figure 6 As shown, the upper shell 2 of the host is provided with a plurality of interfaces 11 for connecting to external terminals, which is convenient for users to use, such as charging the battery, updating the mainboard system, etc.

[0040] To enhance the waterproofing of the modular host structure, this embodiment includes a host sealing ring 5, located between the upper and lower housings 2 and 1, to seal the host cavity and provide waterproof and dustproof features. A battery sealing ring 6 is also included, with an annular boss 116 positioned along the outer edge of the second groove. This ensures a waterproof connection between the battery and the host. Also included are waterproof connectors, which serve as connectors for several external wiring connections and connect to the wiring harness within the cavity via the circuit interface 3.

[0041] Because the modular mainframe structure is independently designed, heat dissipation equipment can be installed to dissipate heat specifically from the circuit boards, improving the quadruped robot's performance. In this embodiment, a fan 7 is included, and a third recess 210 is provided on the outer side of the mainframe upper shell 2 to accommodate the fan 7. This reduces the temperature inside the mainframe and improves the quadruped robot's performance.

[0042] The groove design enables the embedding and fixation of the fan 7, ensuring that the fan 7 can effectively extract the surrounding hot air while running, while reducing noise interference, creating a cooler operating environment for the host. It also includes a cooling plate 8, which is located on the inner side of the upper shell 2 of the host, opposite to the position of the fan 7, so as to cool the mainboard. The cooling plate 8 can actively absorb and transfer the heat generated during the operation of the host, and achieve local rapid cooling. It complements the passive heat dissipation method of the fan 7. The dual use of the cooling plate 8 and the fan 7 greatly enhances the heat dissipation effect, effectively avoiding the risk of performance degradation or damage of the host due to overheating, thereby ensuring the long-term stable operation of the host and extending its service life.

[0043] A quadruped robot comprises a body shell, a motion module and the above-mentioned modular host structure of the quadruped robot, wherein the modular host structure of the quadruped robot is accommodated in the body shell, and the motion module is connected to the body shell.
