[0036] The detection device 3 includes a first detection component 30 and a second detection component 31. The first detection component 30 and the second detection component 31 are arranged on opposite sides of the shell 2. The first detection component 30 and the second detection component 31 are electrically connected to the robot body 1 respectively, and the first detection component 30 and the second detection component 31 are arranged relatively tilted.

[0037] In the above embodiment, the sweeping robot includes a robot body 1, a shell 2, and a detection device 3, wherein the robot body 1 is the core part of the sweeping robot, responsible for performing various cleaning tasks, such as vacuuming, sweeping, etc. It is the function realization center of the entire sweeping robot, and the shell 2 plays the role of protecting and accommodating other components. The accommodating chamber in the shell 2 provides an installation space for the robot body 1, so that the robot body 1 can be stably placed therein, and the shell 2 is connected to the robot body 1. This connection method can be a fixed connection to ensure that the relative positions of the various components of the robot are stable during operation, or it can be a connection method that is easy to disassemble and repair. The detection device 3 is used to sense obstacle information in the surrounding environment. The detection device 3 includes a first detection component 30 and a second detection component 31, which are respectively located on opposite sides of the shell 2. This relative position setting makes the detection The detection range is wider, and the first detection component 30 and the second detection component 31 are arranged relatively tilted. The purpose of this design is not only to detect obstacles in the front direction of the sweeping robot, but also to effectively sense obstacles above and below the side. They are electrically connected to the robot body 1 and can transmit the detected information to the robot body 1 in time so that the robot body 1 can make corresponding obstacle avoidance actions or path adjustment decisions; when the sweeping robot is moving, the first detection component 30 and the second detection component 31 continue to work. Since they are arranged relatively tilted, they can cover a larger detection range. When the first detection component 30 or the second detection component 31 detects an obstacle in front, above or below the side, it will immediately transmit the signal to the robot body 1. After the robot body receives the obstacle information from the detection component, it analyzes and makes decisions according to the preset algorithm. If an obstacle is directly in front of the robot and relatively close, the robot body 1 may immediately stop and turn in an appropriate direction to avoid it. If an obstacle is detected from the side, above, or below, the robot body 1 adjusts its height or direction of movement based on the obstacle's specific location and distance, ensuring continued cleaning without colliding with the obstacle. The relative tilt of the first and second detection components 30 and 31 allows the robot to sense obstacles in all directions. Furthermore, the housing 2 is provided with multiple ultrasonic holes 4 for the ultrasonic device and multiple laser holes 5 for the line laser device. In actual use, whether in open spaces or narrow corners, the robot can promptly detect obstacles in front, above, or below, significantly reducing the risk of colliding with furniture or walls and effectively protecting both the furniture and the robot from damage. This comprehensive sensing capability enables the robot to more intelligently plan its cleaning path in complex environments. When encountering an obstacle, the robot can quickly react and adjust its path, avoiding unnecessary stops and repeated cleaning, thereby improving overall cleaning efficiency. Even in confined spaces, the robot can accurately determine the size and location of obstacles, achieving efficient cleaning.

This connection method and position relationship ensure that the detection body 32 is stable during the operation of the sweeping robot. During the movement, there will be no displacement or shaking due to vibration, collision or other external forces, which ensures the normal operation and detection accuracy of the detection device 3. Since the first support part 330, the second support part 331 and the third support part 332 are an integrated part and are respectively connected to the first support platform 24, the detection body 32 and the second support platform 26, a stable overall structure is formed.

The conductive cotton 35 is arranged at one end of the third supporting part 332 away from the second supporting part 331, and extends along the entire length direction of the third supporting part 332. This arrangement enables the conductive cotton 35 to be closely combined with the third supporting part 332, and at the same time, be in a suitable position in the internal structure of the sweeping robot, so as to realize its function of preventing static electricity. The connection between the conductive cotton 35 and the third supporting part 332 can be through pasting, inlaying and the like, so as to ensure that the conductive cotton 35 will not fall off or displace during the operation of the robot. From the overall structure, the conductive cotton 35 establishes an indirect connection relationship with other parts of the detection device 3 and the shell 2 of the sweeping robot through the third supporting part 332, and becomes an important part of the entire circuit system and electromagnetic shielding system, which helps to improve the structural integrity of the entire detection device 3, and prevent the loosening and displacement between the components.

The height and width of the barrier strip 27 are determined according to specific design requirements and usage scenarios. Generally, it has a certain strength and rigidity and can play a role of blocking and protecting. The buffer pad 28 is located on the side of the barrier strip 27 away from the shell body 20 and is connected to the first inclined cover 210. The buffer pad 28 is usually made of elastic material, such as rubber, silicone, etc. Its length is less than or equal to the length of the barrier strip 27, and its width and thickness are also designed according to actual needs. The function of the buffer pad 28 is to play a role of buffering and shock absorption when the sweeping robot collides with external objects, reducing In order to reduce the damage of impact force to the robot and surrounding objects, the barrier strip 27 surrounds the outer periphery of the first inclined cover 210 to form a protective frame, and the buffer pad 28 is attached to the outer side of the barrier strip 27, and together with the barrier strip 27 and the first inclined cover 210, it constitutes a multi-level protective structure. When the sweeping robot is working, whether it is in contact with an object from the side or the front, the barrier strip 27 first plays a role of blocking and preliminary protection to prevent the object from directly hitting the detection components and other important structures on the first inclined cover 210. If the collision force is large, the buffer pad 28 will further play a role, absorbing and dispersing the impact force through its own elastic deformation, protecting the internal components of the robot and objects colliding with it from excessive damage. This positional relationship and connection method enable the barrier strip 27 and the buffer pad 28 to work together, effectively improving the safety and reliability of the sweeping robot in complex environments.

[0054] Reference Figure 1-Figure 5 In one embodiment, the first detection component 30 and the second detection component 31 are respectively located in the middle position of the first inclined cover 210 and the second inclined cover 211, so that the first detection component 30 and the second detection component 31 are located on the same central axis, and the angle between the sensing plane of the first detection component 30 and the sensing plane of the second detection component 31 is greater than or equal to 90 degrees.

[0055] In the above embodiment, the first detection component 30 is located in the middle of the first inclined cover 210, and the second detection component 31 is located in the middle of the second inclined cover 211, and the two are located on the same central axis, which means that from the front perspective of the sweeping robot, the first detection component 30 and the second detection component 31 are aligned in the horizontal direction. At the same time, the angle between the sensing plane of the first detection component 30 and the sensing plane of the second detection component 31 is greater than or equal to 90 degrees. The sensing plane can be understood as the plane where the coverage range of the effective detection signal of the detection component is located. This angle setting makes the detection ranges of the two detection components have a large overlap and complementary area in space, which can more comprehensively cover the space around the sweeping robot. For example, when the sensing plane of the first detection component 30 mainly covers When the sensing plane of the second detection component 31 covers the area directly in front and at a certain angle to the side and below, it can realize all-round obstacle detection in the forward direction and surrounding area of ​​the sweeping robot. The collaborative work of the two detection components can verify and supplement the detection information of each other. When one detection component may cause inaccurate detection results due to environmental interference or its own failure, the other detection component can provide additional information for reference and correction, thereby improving the overall detection accuracy and reliability. For example, in a complex lighting environment, the laser sensor may be interfered with, but the ultrasonic sensor may not be affected. The cooperation between the two can more accurately judge the situation of obstacles, ensuring that the sweeping robot can always maintain good obstacle detection capabilities and cleaning efficiency.
