[0050] Considering the interactive function of the pet companion robot, a touch sensing module can be added to the housing 1 so that the robot can better respond to the touch of the pet or user and provide a richer interactive experience.

[0051] The utility model significantly improves the performance of the pet companion robot. The new auxiliary wheels not only reduce the noise generated during operation and improve the grip of the pet companion robot under various ground conditions, but also reduce the risk of objects getting stuck due to the simplified structure, making cleaning and maintenance easier, thereby increasing the overall service life.

[0052] Optionally, the connecting column 226 is further provided with a locking piece 227 and a hollow nail of the fixing piece 224; 225, the hollow nail of the fixing piece 224; 225 is sleeved on the connecting column 226, and the locking piece 227 is sleeved on the hollow nail of the fixing piece 224; 225;

[0054] In the auxiliary wheel 22 structure of the pet companion robot, in order to further improve the operability and maintenance convenience of the robot, the design of the connecting column 226 can be replaced by introducing a height-adjustable mechanism, such as using a connecting column with a spiral lifting function. In addition, in order to increase the adaptability of the robot in different environments, a sensor module, such as a ground texture sensor, can be added to the swivel seat 221 or the roller 228 to adjust the robot's movement strategy in real time to adapt to different ground conditions.

[0055] The advantage of the design is that by adopting the silent wheel 223 and the locking mechanism including the locking plate 227 and the fixing plate 225 hollow nail 224, not only lower operating noise is achieved and the user experience is improved, but also the stability and safety of the robot during use are increased through the fixing and locking functions.

[0056] Optionally, a feeding module 3 is also provided, and a top cover 11 is detachably provided on the outer shell 1. The feeding module 3 includes a storage box 31, a chassis 32, a third motor 33, a rotating shaft 34, a feeding tube 35 and a plurality of evenly distributed storage grids 36.

It is also possible to consider adding a liquid storage and distribution system to the feeding module to provide a pet drinking water solution to further enhance the functionality of the robot.

[0058] The advantage of this design is that through intelligent and precise control of the feeding mechanism, it can not only ensure that the pet gets the right amount of food on time, but also automatically adjust the feeding plan according to the pet's actual consumption, thereby optimizing the pet's dietary health.

In the design of the charging module of the pet companion robot, considering enhancing the automatic docking capability, more advanced navigation and docking technology can be introduced to replace or assist the existing distance sensor 47, such as using a high-precision laser navigation system or visual recognition system to improve the accuracy and efficiency of the robot's autonomous search for the charging seat and complete docking. In addition, in order to improve safety and user experience, an intelligent temperature control system can be added to the charging module to monitor the temperature changes during the charging process in real time, prevent overheating, and ensure charging efficiency and safety.

[0061] Optionally, an interactive module 5 is also provided, which includes: a binocular camera 51, an infrared spotlight 52, a night vision light 53, a first circuit board 54 and a speaker 55, wherein the speaker 55 is located at the bottom of the housing 1, and the night vision light 53 is placed in the middle of the binocular camera 51, and the binocular camera 51, the infrared spotlight 52, the night vision light 53, the speaker 55 are electrically connected to the first circuit board 54.

[0062] In the interactive module design of the pet companion robot, in order to enhance the interactive experience and functional diversity, it is possible to consider introducing a touch screen or interactive projection technology to replace or assist the existing binocular camera 51 and speaker 55 combination. Such technology can provide a more intuitive interactive method and rich visual content to meet the different needs of pets and owners. In addition, adding environmental perception sensors, such as temperature and humidity sensors and air quality detectors, can allow the robot to better understand the surrounding environment, thereby providing more suitable interactive methods and life tips.

[0063] Through the integration of these technologies, the interactive module can not only provide efficient and accurate night-time monitoring and lighting functions, enhancing the robot's performance under various lighting conditions, but also provide richer entertainment and interactive experiences through enhanced audio-visual interaction.

[0064] Optionally, a communication module 6 is further provided, and the communication module 6 further includes: a third circuit board 61, a signal transmitter 62, a signal receiver 63, and a sound receiver 64, and the signal transmitter 62, the signal receiver 63, and the sound receiver 64 are electrically connected to the third circuit board 61.

[0065] In the design of the communication module of the pet companion robot, in order to enhance the remote interaction and control capabilities, it is possible to consider introducing more advanced wireless communication technologies to replace or assist the existing signal transmitter 62 and signal receiver 63, such as using Wi-Fi 6 or 5G communication technologies to achieve higher speed and lower latency data transmission. In addition, by integrating the intelligent voice assistant function and adding an interface compatible with modern smart home systems, users can control the robot through voice commands, providing a more convenient user experience.

[0066] Optionally, the top cover 11 is fixed to the top of the shell 1 by an elastic clip. The top cover is fixed by an elastic clip, which provides a convenient installation and disassembly method, and is convenient for users to quickly access internal components for maintenance or cleaning. A groove 12 is also provided on the shell 1, and the groove 12 is located below the top cover 11. The groove on the shell is located below the top cover, which provides a convenient gripping point for users to easily open the top cover.

[0068] The feeding tube is inclined at an angle of 20-90 degrees to the bottom of the shell, and at least two protrusions with an angle of 10-30 degrees are set at the bottom of the inner part. This design optimizes the falling path and speed of food and reduces the problem of food blockage during the transmission process. At the same time, the presence of the protrusion helps to evenly disperse the food, ensuring that the amount of food can be effectively controlled each time feeding, and improving the accuracy and efficiency of feeding.

[0069] Optionally, the shell 1 is constructed of a material that is transparent to electromagnetic or optical signals, so that the signal transmission and reception inside the robot are not interfered with, thereby improving communication efficiency and sensor accuracy.

[0070] When working, it first self-checks to confirm that all modules are functioning normally and then stands by. Then it follows the set planned activities, such as patrolling or playing with pets. When feeding time comes, it automatically distributes food, and the special design prevents food from clogging. When the battery is low, the robot returns to the charging station to charge;

[0071] At night, the night vision function is used to monitor pets to ensure their safety. At the same time, the binocular camera and sound equipment monitor the pet's movements, and communication through the speaker deepens the emotional connection between the pet and the robot. The remote control function allows the owner to interact with the pet even when not at home, caring for the pet's needs and safety around the clock.

[0072] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
