[0020] Reference Figure 1A front impact plate for a sweeping robot includes: a base 100, a connecting portion 200, and a reinforcing rib 300. The base 100 is elastic and capable of elastic deformation. The connecting portion 200 is disposed on the base 100, extending outward relative to the base 100, and its edge away from the base 100 is used for thermal fusion connection to the robot. The reinforcing rib 300 is disposed between the base 100 and the connecting portion 200, connecting the two, and extends from the base 100 to the edge of the connecting portion 200 away from the base 100. The front impact plate of this sweeping robot significantly improves structural strength and stability by incorporating the reinforcing rib 300 between the base 100 and the connecting portion 200. The elasticity of the base 100 allows it to undergo elastic deformation upon impact, absorbing impact energy and reducing impact on internal robot components. The connecting portion 200 is used for thermal fusion connection to the robot body, ensuring the secure installation of the front impact plate. The reinforcing rib 300 tightly connects the base 100 and the connecting part 200 together, enhancing the load-bearing capacity and deformation resistance of the entire front impact plate, enabling it to better withstand impact forces and extend its service life. At the same time, the design of the reinforcing rib 300 helps optimize stress distribution, avoiding the risk of fracture caused by stress concentration, and improving the reliability and safety of the front impact plate.

[0021] It is conceivable that a buffer spring would be installed at the front end of the base 100 to further absorb and mitigate the impact force on the robot during collisions. The buffer spring can effectively reduce the burden on the front impact plate, especially when facing larger obstacles, reducing the degree of deformation of the base 100 and the reinforcing rib 300, and extending the service life of the front impact plate.

[0022] In some embodiments, reference is made to Figure 2 The connecting portion 200 is located at the top of the base 100 and bends downwards. One end of the reinforcing rib 300 is connected to the inner wall of the base 100, and the other end of the reinforcing rib 300 is connected to the downward-bent portion of the connecting portion 200. The connecting portion 200, located at the top of the base 100 and bent downwards, forms a stable connection structure. The arrangement of the reinforcing rib 300 connecting one end to the inner wall of the base 100 and the other end to the downward-bent portion of the connecting portion 200 further enhances the bonding strength between the connecting portion 200 and the base 100. When the robot vacuum collides, the reinforcing rib 300 effectively disperses the impact force onto the base 100, reducing the concentrated stress on the connecting portion 200 and thus lowering the risk of breakage during the collision. Furthermore, this design improves the overall rigidity of the front impact plate, keeping it stable during robot movement, reducing loosening caused by vibration or impact, and ensuring the normal operation of the robot.

[0023] Furthermore, longitudinal ribs can be added to the inner wall of the base 100 to form a robust skeleton structure together with the reinforcing ribs 300. The longitudinal ribs can enhance the longitudinal strength of the base 100, and combined with the lateral support of the reinforcing ribs 300, they form a more stable three-dimensional structure, improving the overall torsional and bending resistance of the front impact plate.

[0024] In some embodiments, reference is made to Figure 3 The end of the reinforcing rib 300 connected to the base 100 is the first end, and the end of the reinforcing rib 300 connected to the connecting part 200 is the second end. The dimension of the first end in at least one direction is the same as the dimension of the second end in the same direction. The dimensional difference between the first and second ends of the reinforcing rib 300 allows it to better adapt to the mechanical properties of the base 100 and the connecting part 200. The first end, connected to the inner wall of the base 100, is relatively large and can withstand greater tensile and compressive stresses; the second end, connected to the downwardly bent portion of the connecting part 200, is relatively small and can flexibly adapt to the bending shape of the connecting part 200. This dimensional variation enhances the connection strength between the reinforcing rib 300 and the base 100 and the connecting part 200, while ensuring the flexibility of the connecting part 200. During a collision, the reinforcing rib 300 can effectively transfer the impact force from the connecting part 200 to the base 100, reducing the deformation of the connecting part 200 and improving the stability and reliability of the front impact plate.

[0025] In some embodiments, reference is made to Figure 3 The height of the reinforcing rib 300 gradually increases from the connecting portion 200 to the inner wall of the base 100. This gradual increase in height creates a gradient reinforcement structure. This design allows the reinforcing rib 300 to better adapt to stress concentration during a collision near the connecting portion 200. As it extends towards the base 100, the gradually increasing height provides stronger support and more effectively disperses impact force. During a collision, the change in the height of the reinforcing rib 300 helps guide stress distribution, reducing stress concentration at the connection between the base 100 and the connecting portion 200, and improving the overall impact resistance of the front impact plate. Simultaneously, this gradient design maintains the overall smoothness of the front impact plate, does not negatively impact the robot's mobility, and ensures the robot's normal operation in various complex environments.

[0026] In some embodiments, reference is made to Figure 3The connecting part 200 is provided with connecting piles 400, and multiple reinforcing ribs 300 are respectively arranged on both sides of the connecting piles 400. This arrangement ensures that each connecting pile 400 is symmetrically supported by the reinforcing ribs 300 on both sides, enhancing the stability of the connecting pile 400. When the robot is subjected to a collision, the reinforcing ribs 300 on both sides can jointly bear the impact force, preventing the connecting pile 400 from bending or breaking. The multiple reinforcing ribs 300 also improve the overall rigidity of the front impact plate, enabling it to better withstand multi-directional impact forces and ensuring the stability and reliability of the robot under various collision conditions. Furthermore, the symmetrically distributed reinforcing ribs 300 help balance stress, reduce structural deformation caused by uneven stress, and extend the service life of the front impact plate.

[0027] In some embodiments, reference is made to Figure 4 The reinforcing ribs 300 are arranged in multiple pairs, with each connecting pile 400 having at least one pair of reinforcing ribs 300. Each reinforcing rib 300 is evenly distributed along the length of the connecting portion 200. This even distribution of reinforcing ribs 300 allows the impact force to be evenly distributed across the connecting portion 200, avoiding weak points caused by insufficient local reinforcement. The multiple pairs of reinforcing ribs 300 improve the overall strength and rigidity of the front impact plate, enabling it to withstand greater impact forces, while also enhancing the stability and reliability of the structure. During robot operation, this evenly distributed distribution of reinforcing ribs 300 also reduces the vibration of the front impact plate, improves the robot's operational smoothness, and lowers noise levels.

[0028] In addition, an elastic rubber strip is provided along the length of the connecting part 200 to enhance the buffering performance of the front impact plate. The elastic rubber strip can provide additional elastic deformation upon collision, absorbing more impact energy and reducing the impact on the robot's internal structure. At the same time, the softness of the rubber strip can reduce damage to the colliding object and improve the robot's environmental adaptability.

[0029] In some embodiments, reference is made to Figure 1The outer surface of the base 100 is coated with a wear-resistant coating, and the connecting part 200 is located on the inner surface of the base 100. The wear-resistant coating significantly improves the durability and service life of the front impact plate. The wear-resistant coating effectively resists wear caused by ground friction and collisions, protecting the base 100 from damage and ensuring that the elasticity and strength of the front impact plate are not affected. Placing the connecting part 200 on the inner surface of the base 100 not only reduces the friction and collisions experienced by the connecting part 200 on the outside of the robot but also optimizes the robot's appearance design, making it more concise and aesthetically pleasing. Furthermore, the built-in connecting part 200 reduces the risk of the front impact plate detaching due to impacts from external objects, improving the overall safety of the robot.

[0030] It is conceivable that the wear-resistant coating could also be replaced with a removable wear-resistant sleeve on the front impact plate, installed in areas with frequent contact with the ground. The use of the wear-resistant sleeve effectively protects the base of the front impact plate from wear, extending its service life. When the wear-resistant sleeve wears out, the user can easily replace it, reducing maintenance costs while maintaining the robot's optimal performance.

[0031] In some embodiments, reference is made to Figure 1 The base 100, connecting part 200, and reinforcing rib 300 are designed as a single molded component. This integrated design eliminates potential weaknesses caused by component splicing, significantly improving the overall strength and rigidity of the front impact plate. The integrated design ensures a seamless connection between the base 100, connecting part 200, and reinforcing rib 300, reducing stress concentration points and improving structural stability and reliability. During production, the integrated manufacturing process simplifies production steps, reduces production costs, and increases production efficiency. This design also enhances the front impact plate's waterproof and dustproof performance, reducing the risk of malfunctions caused by water or dust entering the robot and extending its service life.

[0032] Specifically, the base 100 has flow channels on both sides of its edges. These channels guide and manage the airflow generated during a collision. The flow channels reduce air resistance, improve the robot's movement efficiency, and guide airflow during a collision, reducing component swaying caused by airflow impact and enhancing the robot's stability.

[0033] In some embodiments, reference is made to Figure 1The base 100, connecting part 200, and reinforcing rib 300 are made of soft rubber. The use of soft rubber in the base 100, connecting part 200, and reinforcing rib 300 gives the front impact plate excellent elastic recovery and impact resistance. The soft rubber material can elastically deform upon impact, absorbing impact energy and reducing the impact force on the robot's internal components. At the same time, the flexibility of the soft rubber material allows it to maintain good performance even after repeated impacts, without becoming brittle or permanently deformed. This material choice improves the durability and reliability of the front impact plate, extending its service life. The soft rubber material also has a certain shock absorption effect, reducing the robot's vibration and noise levels during operation, improving the robot's operational smoothness and user experience.

[0034] Furthermore, a proximity sensor is integrated on the outer surface of the substrate 100 to detect the distance to obstacles ahead. The proximity sensor can detect the presence of obstacles in advance, giving the robot an opportunity to adjust its path, reduce unnecessary collisions, and protect the front impact plate and the robot itself. Sensor data can also be used to optimize the robot's navigation algorithm, improving cleaning efficiency and coverage.

[0035] In some embodiments, reference is made to Figure 1 The substrate 100, connecting portion 200, and reinforcing rib 300 are made of thermoplastic elastomer or thermoplastic polyurethane. The use of thermoplastic elastomer or thermoplastic polyurethane combines the elasticity of rubber with the processing convenience of plastics. Thermoplastic elastomers and thermoplastic polyurethanes possess excellent elasticity and resilience, enabling them to quickly return to their original shape after an impact, ensuring that the shape and function of the front impact plate remain unaffected. These materials also exhibit good wear resistance and weather resistance, resisting wear and environmental factors during prolonged use and extending the service life of the front impact plate. Furthermore, their excellent processing performance allows for large-scale production through processes such as injection molding, reducing production costs, improving production efficiency, and meeting market demands.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
