Description

TECHNICAL FIELD

[0001] The present application relates to the field of robots, in particular to a mobile monitoring robot. BACKGROUND

[0002] In the application field of traditional mobile monitoring robots, automatic recharging is one of the key technologies to ensure continuous monitoring. These robots are usually equipped with batteries and need to automatically return to the charging base for charging when the power is insufficient. However, existing mobile monitoring robots often face the problem of inaccurate path when performing the recharging task, which leads to the robot being unable to accurately dock the charging port, thereby affecting the charging efficiency and the continuity of the monitoring task. This inaccurate path may be due to environmental factors, positioning errors of the robot itself, or limitations of the navigation algorithm.

[0003] In order to solve the problem of mobile monitoring robots in correcting the recharging path to achieve accurate charging, the existing technology proposes a magnetic attraction calibration scheme. This scheme installs a magnet and a magnetic sensor on the charging base and the robot respectively, and guides the robot to accurately dock the charging port through the magnetic attraction effect. When the robot approaches the charging base, the magnetic sensor can sense the change of the magnetic field intensity of the magnet, so as to adjust the moving direction of the robot to ensure that it can enter the charging position along the correct path. This magnetic attraction calibration method improves the accuracy of recharging to a certain extent and enhances the autonomous charging ability of the robot.

[0004] Although the existing technology solves the problem of recharging path correction of mobile monitoring robots to a certain extent through magnetic attraction calibration, there are still some defects. First of all, the magnetic attraction calibration scheme depends on the accurate installation and calibration of the magnet and the magnetic sensor, and once these components deviate or are damaged, it will directly affect the accuracy of recharging. Secondly, the magnetic attraction may be disturbed by the surrounding environmental factors, such as the presence of metal objects which may change the magnetic field distribution, leading to the robot misjudging the path. In addition, the magnetic attraction calibration scheme increases the complexity and cost of the system. UTILITY MODEL CONTENT

[0037] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0038] Please refer to Figures 1-6 Embodiments of the present application provide a mobile monitoring robot 100, comprising:

[0039] A monitoring vehicle body 1 and a charging base 2, the monitoring vehicle body 1 being capable of returning charging along a straight path;

[0040] The monitoring vehicle body 1 comprises a set of driving wheels 3 on both sides thereof and a driven wheel 4 arranged at the bottom, the driven wheel 4 being used for balancing the vehicle body;

[0041] The charging base 2 is provided with a return charging unit 5, which is in a U-shaped structure and has a correction channel 6 parallel to the return charging path formed inward along the opening direction of the return charging unit 5. In the direction of the return charging path, the correction channel 6 is gradually narrowed on both sides along the direction close to the central axis of the return charging unit 5.

[0042] The return charging unit 5 is provided with a charging port 7, and the driven wheel 4 slides in the correction channel 6 and abuts against the end of the correction channel 6 to make the monitoring vehicle body 1 abut against the charging port 7.

[0043] Specifically, the monitoring vehicle body 1 is equipped with a driving wheel group 3 on both sides, which can autonomously navigate and return to the charging base 2 along a predetermined straight path. The bottom provided driven wheel 4 not only plays a role in balancing the vehicle body, but also plays a key guiding role in the return charging process. The charging base 2 is ingeniously designed with a U-shaped return charging unit 5, which has a correction channel 6 formed inside, and the channel is gradually narrowed on both sides. This design can accurately guide the monitoring vehicle body 1 into the correct charging position. The design of the correction channel 6 not only improves the accuracy of the return charging, but also significantly reduces the need for manual intervention, enhances the continuity and automation level of the monitoring task. In addition, this compact and reasonably designed mobile monitoring robot can perform well in various application scenarios such as home security monitoring and industrial automation monitoring, greatly improving the monitoring efficiency and management convenience.

[0044] In a specific embodiment, the return charging unit 5 includes a correction part 8 and a buffer part 9, which are arranged in sequence in the length direction of the correction channel 6, and the buffer part 9 is arranged at the end of the correction channel 6. When the monitoring vehicle body 1 returns to charge, the monitoring vehicle body 1 abuts against the correction part 8 and the buffer part 9 in sequence.

[0045] Specifically, the correction part 8 is located at the front end of the return charging unit 5, responsible for preliminary adjustment of the position of the monitoring vehicle body 1, ensuring that it can smoothly enter the correction channel 6. The buffer part 9 is located at the end of the correction channel 6, which plays a role in further buffering and stabilizing the vehicle body. This design not only improves the stability and safety of the return charging process, but also effectively avoids collisions and damage caused by excessive speed or position deviation of the monitoring vehicle body 1. The close connection and reasonable position relationship between the correction part 8 and the buffer part 9 make the entire return charging process more smooth and efficient, further improving the reliability and durability of the mobile monitoring robot.

[0046] In a specific embodiment, the end of the driving wheel set 3 is inclined along the direction close to the central axis of the vehicle body, and the charging base 2 is also provided with a retention groove 10 recessed inward relative to the driving wheel.

The retention groove 10 is located on the charging base 2, and its shape matches the driving wheel set 3. When the monitoring vehicle body 1 is charging, the driving wheel set 3 partially extends into the retention groove 10, effectively preventing the vehicle body from sliding out of the charging base 2 due to external interference or misoperation. This design not only enhances the stability of the vehicle body, but also improves the reliability and safety of the charging process, avoiding the problem of monitoring task failure caused by charging interruption.

[0048] In a specific embodiment, the charging base 2 further includes a sliding surface 11 in contact with the driving wheel set 3, and the return charging unit 5 and the retention groove 10 are both arranged on the sliding surface 11.

[0049] Specifically, the sliding surface 11 of the charging base 2 is innovatively designed to be recessed along the central axis to form a recessed arc 12. This design cleverly utilizes the physical principle that when the monitoring vehicle body 1 slides along the correction channel 6, the recessed arc 12 can pull the vehicle body to deviate along the direction close to the central axis of the sliding surface 11, thereby ensuring that the vehicle body can accurately dock with the charging port 7. This design not only simplifies the complexity of the return charging process, but also improves the accuracy and efficiency of path correction. At the same time, the design of the recessed arc 12 also enhances the structural strength and stability of the charging base 2, further improving the durability and reliability of the entire mobile monitoring robot.

[0050] In a specific embodiment, the charging port 7 is provided with a charging gasket 13, and the bottom end of the monitoring vehicle body 1 is provided with an inductive interface 14.

[0051] Specifically, the charging port 7 is provided with a charging gasket 13, and the bottom end of the monitoring vehicle body 1 is provided with an inductive interface 14. When the monitoring vehicle body 1 is accurately docked with the charging port 7, the charging gasket 13 and the inductive interface 14 are in close contact, realizing wireless charging. This design not only simplifies the structure of the charging interface, improves the convenience and reliability of charging, but also avoids the cable management problem brought by the traditional wired charging method. At the same time, the wireless charging method also improves the flexibility and freedom of the monitoring vehicle body 1, so that it can freely move in various complex environments and perform monitoring tasks.

At the same time, the design of the electrical connection hole 15 improves the flexibility and practicality of the charging base 2, making it adaptable to various complex environments and conditions.

[0056] In a specific embodiment, the charging base 2 is also provided with a wire storage groove 16, which is located at the lower end of the electrical connection hole 15, and the wire storage groove 16 is used to place the excess wire when connecting electricity.

[0057] Specifically, the charging base 2 is provided with a wire storage groove 16 for placing excess wire when connecting electricity. This design not only looks neat and tidy, avoiding the safety hazards caused by messy wires, but also improves the overall aesthetics and user experience of the entire mobile monitoring robot. At the same time, the design of the wire storage groove 16 also considers the management and storage of the wire, making the charging process more convenient and efficient.

[0058] In a specific embodiment, the charging base 2 is also provided with an anti-slip pad 17 on the contact surface with the bottom.

[0059] Specifically, the bottom surface is provided with anti-skid pads 17. This design increases the friction between the charging base 2 and the ground, thereby improving the stability during the charging process. The material and structural design of the anti-skid pads 17 are carefully selected and optimized, which can maintain stable friction in various complex environments and conditions, effectively preventing the charging base 2 from sliding due to wet or uneven ground. This design not only improves the safety and reliability of the charging process, but also further enhances the durability and stability of the entire mobile monitoring robot.
