The robot chassis 1 is provided with a female connector 4, and the robot housing 2 is provided with a male connector 6 corresponding to the female connector 4. The female connector 4 is mounted on a mounting base 5. A hardware circuit board 3 is installed inside the mounting base 5. The hardware circuit board 3 is equipped with a current detection module, a voltage detection module, a temperature detection module, and an access detection module. The male connector 6 is provided with six elastic pins 61. This quick interface has a total of six elastic pins, namely positive power, negative power, two pins for communication (CAN, 485, etc.), and two pins for detecting whether the connection is successful. The usage method of this quick interface is as follows: Figure 3 The robot chassis 1 and robot housing 2 modules are respectively equipped with female and male connectors. When the chassis and housing are assembled together, the spring pins will insert into the corresponding positions and maintain the connection through their own elasticity.

[0025] When the robot chassis 1 and robot housing 2 are not connected, the voltage sampled by the MCU_ADC is approximately equal to VCC. At this time, the processor determines that the two modules are not connected, and the robot chassis 1 will not supply power to the robot housing 2. When the robot chassis 1 and robot housing 2 are correctly connected, R1, R3, R2, and R4 form a circuit. R2 and R3 are connected in parallel and then connected in series with R1 and R4. At this time, the voltage sampled by the MCU_ADC is 1 / 4VCC. It is then considered that the two modules are successfully connected, the robot chassis 1 supplies power to the robot housing 2, and it begins to work normally.

[0026] Preferably, the mounting base 3 has a mounting plate 7 inside, and the first fan 12 is mounted on the side of the mounting plate 7 near the female head 4.

[0027] In a preferred embodiment, a cooling box 8 is installed on the bottom side of the mounting plate 7 away from the female connector 4. The cooling box 8 is filled with coolant and equipped with a micro circulation pump 9. The outlet end of the micro circulation pump 9 is connected to a first pipe 10, and the other end of the first pipe 10 is connected to a cooling sleeve 11. The cooling sleeve 11 is fitted onto the inner outer wall of the female connector 4. The top of the cooling sleeve 11 is connected to a second pipe 13, and the other end of the second pipe 13 is connected to the top of the cooling box 8. The micro circulation pump 9 can continuously dissipate heat from the female connector 4, preventing excessive heat at the interface and thus improving safety performance.

[0028] In a preferred embodiment, a heat dissipation fin 15 is fitted onto the outer wall of the second pipe 13, and the heat dissipation fin 15 is made of copper-aluminum alloy.

[0029] In a preferred embodiment, a second fan 14 is mounted on the middle of the side of the mounting plate 7 away from the female head 4.

[0031] In a preferred embodiment, the air outlet of the second fan 14 is positioned towards the heat dissipation fins 15. The second fan 14 can cool the coolant, which facilitates the cooling jacket 11 to continuously cool the female head 4 with water. Therefore, the heat dissipation method of the present invention is reasonable, and the cooperation of multiple heat dissipation mechanisms can achieve the best heat dissipation effect, thereby effectively improving the connection stability of the service robot.

[0032] Working principle of the invention:

[0033] This invention replaces the traditional wire connection method with a quick interface structure, making robot module assembly and replacement more convenient and faster. Compared with the original system architecture, the new system supports more functions and has greatly increased scalability.

[0034] It is worth noting that the robot chassis of this invention can not only hold boxes, but also other functional modules. Each module has such an interface, which allows for quick replacement of other modules. This is because the existence of this interface makes it easier to replace other modules.

[0035] The microcontroller located in robot chassis 1 will continuously acquire voltage data from the MCU_ADC terminal, based on... Figure 1When the robot chassis 1 and the robot housing module are not connected, the voltage collected by the MCU_ADC terminal is approximately 3.3V. At this time, the processor determines that the two modules are not connected, and the robot chassis 1 will not supply power to the robot housing module. When the robot chassis 1 and the robot housing module are correctly connected, R1, R3, R2, and R4 form a circuit. R2 and R3 are connected in parallel and then connected in series with R1 and R4. At this time, the voltage collected by the MCU_ADC is 0.8V-0.9V. It is considered that the two modules are successfully connected, the robot chassis 1 supplies power to the robot housing module, and it starts to work normally. The robot chassis 1 can also control the robot housing module.
