Description

Technical Field

[0001] This utility model relates to the field of sweeping machine technology, and in particular to a sweeping machine chassis structure with anti-collision function. Background Technology

[0002] In a home environment, robotic vacuum cleaners need to clean complex floor surfaces, including furniture, corners, and carpet edges. They may collide with furniture, especially when turning, entering room corners, or cleaning low areas. The anti-collision chassis can effectively protect the equipment when the robotic vacuum cleaner collides with furniture, buffering the impact and preventing damage to the chassis and cleaning structure, thus ensuring the stable operation of the equipment for a long time.

[0003] The chassis structure of a sweeper with anti-collision function typically includes obstacle avoidance sensors, cushioning materials, rotating or adjustable impact protection devices, and intelligent control devices. The working principle is to monitor the surrounding environment in real time through sensors. When an obstacle is detected, the system automatically controls the chassis to avoid it, or reduces the impact force through the chassis's anti-collision devices, ensuring that the equipment avoids damage to obstacles or itself during the cleaning process.

[0004] In existing technologies, the chassis structure of sweeping machines mainly relies on the impact resistance of the outer shell and built-in electronic components to ensure the stable operation of the equipment. However, during the sweeping process, corners, obstacles, or narrow spaces are frequently encountered, making it difficult to effectively avoid collisions with obstacles. This can easily cause direct impacts on the chassis, leading to deformation of the outer shell and damage to the chassis and internal components. The chassis structure of sweeping machines is at high risk of damage, affecting its service life and working performance. Therefore, a sweeping machine chassis structure with anti-collision function is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a sweeper chassis structure with anti-collision function, which solves the problem that the internal structure is easily damaged by impact when encountering corners and obstacles.

[0006] To achieve the above objectives, this utility model provides a sweeper chassis structure with anti-collision function, including a sweeper body, a control button fixedly connected to the top of the sweeper body, multiple side and bottom anti-collision mechanisms fixedly connected to the outer side of the sweeper body, a top anti-collision mechanism fixedly connected to the inside of the sweeper body, the side and bottom anti-collision mechanisms including multiple telescopic columns, the inner sides of the multiple telescopic columns fixedly connected to the outer side of the sweeper body, springs sleeved on the outer side of the telescopic columns, anti-collision arc plates fixedly connected to the outer side of the telescopic columns, an anti-fall plate fixedly connected to the bottom of the sweeper body, and a cleaning component fixedly connected to the bottom of the sweeper body.

[0007] The cleaning component includes a sweeping plate, which is externally fixedly connected to the inside of the sweeper body. A floor cleaning unit is internally fixedly connected to the sweeper body.

[0008] The top anti-collision mechanism includes two fixed shafts, which are externally fixedly connected to the inside of the sweeper body. A rotating plate is rotatably connected to the outside of the fixed shafts, and a connecting block is rotatably connected to the inside of the rotating plate. A pushing assembly is fixedly connected to the inside of the sweeper body, and multiple anti-collision blocks are fixedly connected to the pushing assembly.

[0009] The pushing component includes a cylinder, which is externally fixedly connected to the inside of the sweeper body, and a sensor is fixedly connected to the output end of the cylinder.

[0010] The anti-collision arc plate and the anti-collision block are both made of rubber.

[0011] The outer side of the sensor is slidably connected to the inner side of the sweeper body, and the inner sides of the two connecting blocks are fixedly connected to the outer side of the sensor.

[0012] The outer sides of the two rotating plates are rotatably connected to the inner side of the sweeper body, and the inner sides of the multiple springs are fixedly connected to the outer side of the sweeper body.

[0013] This utility model discloses a sweeper chassis structure with anti-collision function. The sweeper cleans the ground through the cleaning components at the bottom. The cleaning plate rotates and the internal suction structure sucks in dust and impurities, cleaning the floor. When it collides with corners or objects, the telescopic column on the inner side of the anti-collision arc plate extends and retracts, the spring is compressed, and the sensor on the top detects the collision and automatically changes the route. At the same time, it can protect the inner side of the sweeper body and the cleaning structure of the chassis. It can effectively reduce the impact on the cleaning structure and internal components such as the motor when the sweeper collides with obstacles, thereby extending the service life of the sweeper.

[0014] This utility model discloses a sweeper chassis structure with anti-collision function. When the sensor enters a low area such as under a bed or cabinet, the drive cylinder extends and retracts to move the sensor downward, allowing the sweeper to better adapt to complex environments, effectively avoid obstacles, and prevent getting stuck or colliding. One side of the rotating plate is fixed inside the sweeper body by a fixed shaft, and the other side is connected to the sensor by a connecting block to ensure the stability of the sensor during the downward movement.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1 , Figure 2 and Figure 4 This utility model provides a technical solution: a sweeper chassis structure with anti-collision function, including a sweeper body 1. The sweeper body 1 is the core load-bearing component of the entire sweeper, providing the installation foundation and structural support for all structures, ensuring that all components can work stably and collaboratively. A control button 2 is fixedly connected to the top of the sweeper body 1. By operating the control button 2, the sweeper can be started and stopped, and the sweeping mode can be switched, etc., which is convenient for users to operate according to actual cleaning needs. Multiple side and bottom anti-collision mechanisms 3 are fixedly connected to the outside of the sweeper body 1. The side and bottom anti-collision mechanisms 3 can provide all-round protection for the sides and bottom of the sweeper body 1. During the movement of the sweeper, it can effectively resist the collision impact from the side and below. A top anti-collision mechanism 4 is fixedly connected inside the sweeper body 1. The top anti-collision mechanism 4 focuses on protecting the internal upper structure of the sweeper body 1, preventing the top sensor 442 from being damaged by collision, and at the same time assisting in the realization of obstacle sensing and avoidance functions.

[0023] The side-bottom anti-collision mechanism 3 includes multiple telescopic columns 31. The inner sides of the multiple telescopic columns 31 are fixedly connected to the outer side of the sweeper body 1. The telescopic columns 31 can extend and retract when the sweeper collides, providing buffer space for the impact and preventing the impact force from being directly transmitted to the sweeper body 1. Springs 32 are sleeved on the outer side of the telescopic columns 31. The inner sides of the multiple springs 32 are fixedly connected to the outer side of the sweeper body 1. When the sweeper collides with an obstacle, the springs 32 will be compressed. The elastic deformation of the springs 32 absorbs the impact force generated by the collision, further enhancing the buffering effect. Anti-collision arc plates 33 are fixedly connected to the outer side of the telescopic columns 31. The anti-collision arc plates 33 are made of rubber. The rubber material has good elasticity and wear resistance. It can not only directly contact the obstacle to reduce wear during the collision, but its arc structure can also disperse the collision force and reduce the local stress intensity.

[0024] A fall protection plate 34 is fixedly connected to the bottom of the main body 1 of the sweeper. The fall protection plate 34 is fixed to the bottom of the main body 1 of the sweeper and extends beyond the bottom range of the main body 1 of the sweeper. The fall protection plate 34 is connected to a sensor 442. When the main body 1 of the sweeper moves forward, it detects the road conditions ahead and prevents the bottom structure of the sweeper from being damaged when going up or down slopes or falling slightly. A cleaning component 35 is fixedly connected to the bottom of the main body 1 of the sweeper. The cleaning component 35 is the core component for realizing the sweeper's cleaning function and is responsible for completing the cleaning process. The cleaning component 35 includes a sweeping plate 351, which is externally fixedly connected to the inside of the sweeper body 1. The sweeping plate 351 sucks up dust and impurities by rotating and having an internal suction structure, efficiently collecting debris from the ground and ensuring cleaning effect. A floor cleaning 352 is fixedly connected inside the sweeper body 1. After the sweeping plate 351 has collected the debris, the floor cleaning 352 can further wipe the ground to remove residual stains and improve the cleanliness of the ground.

[0025] like Figures 2 to 4As shown, the top anti-collision mechanism 4 includes two fixed shafts 41. The two fixed shafts 41 are externally fixedly connected to the inside of the sweeper body 1. The fixed shafts 41 provide stable mounting and rotation fulcrums for the rotating plate 42, ensuring that the rotating plate 42 can rotate stably around the fixed shafts 41 during subsequent movement. The rotating plate 42 is rotatably connected to the outside of the fixed shafts 41. The outer sides of the two rotating plates 42 are rotatably connected to the inside of the sweeper body 1. One side of the rotating plate 42 is fixed inside the sweeper body 1 by the fixed shafts 41, and the other side is connected to the sensor by the connecting block 43. The sensor 442 is connected and can rotate synchronously with the movement of the sensor 442 to ensure the stability of the sensor 442 during the downward slide. The inner side of the rotating plate 42 is rotatably connected to the connecting block 43. The inner sides of the two connecting blocks 43 are fixedly connected to the outer side of the sensor 442. The connecting block 43 serves to connect the rotating plate 42 and the sensor 442, so that the force between the two can be effectively transmitted, while allowing a certain angle of rotation to adapt to the movement trajectory of the sensor 442.

[0026] A pushing assembly 44 is fixedly connected inside the main body 1 of the sweeping machine. The pushing assembly 44 provides power for the movement of the sensor 442, ensuring that the sensor 442 can adjust its position according to actual needs. The pushing assembly 44 includes a cylinder 441, which is externally fixedly connected inside the main body 1 of the sweeping machine. When the sensor 442 enters a low area such as under a bed or cabinet, the cylinder 441 can be driven to extend or retract, providing power for the movement of the sensor 442. The output end of the cylinder 441 is fixedly connected to the sensor 442, and the outer side of the sensor 442 is slidably connected to the inner side of the main body 1 of the sweeping machine. The top sensor 442 can automatically control the sweeper to change its route after detecting a collision. At the same time, when entering a low area, it slides downward with the extension and retraction of the cylinder 441, which allows the sweeper to better adapt to complex environments, effectively avoid obstacles, and avoid getting stuck or colliding. It can also protect the inner side of the sweeper body 1 and the cleaning structure of the chassis. The push component 44 is fixedly connected with multiple anti-collision blocks 45. The anti-collision blocks 45 are made of rubber. The rubber anti-collision blocks 45 can form a protection around the push component 44. When an external force collides with the push component 44, it can absorb the impact force and protect the inner sensor 442.

[0027] Working principle: By operating the control button 2 on the top of the sweeper body 1, the sweeper can be started and a suitable cleaning mode can be selected. After the sweeper is started, the bottom cleaning component 35 begins to operate. The sweeping plate 351 rotates and works in conjunction with the internal suction structure to suck up dust and impurities from the ground to complete the collection of debris. Subsequently, the floor cleaning component 352 inside the sweeper body 1 further wipes the ground to remove residual stains. During the sweeper's movement and cleaning process, the side and bottom anti-collision mechanism 3 ensures that when the sweeper encounters an obstacle on its side or bottom, the telescopic column is the first part to come into contact with the obstacle. The anti-collision arc plate 33 on the outside of 31 pushes the telescopic column 31 to retract towards the main body 1 of the sweeper after being subjected to force. At the same time, the spring 32 on the outside of the telescopic column 31 is compressed. The collision impact force is buffered by the extension and retraction of the telescopic column 31 and the elastic deformation of the spring 32. If the top sensor 442 detects a collision, it will automatically control the sweeper to change the route. The anti-fall plate 34 at the bottom of the sweeper body 1 works with the sensor 442 to detect the road conditions in advance when the sweeper moves forward, and detect the road conditions that are prone to falling due to the ups and downs in front, so as to avoid damage to the bottom structure.

[0028] Inside the top anti-collision mechanism 4, the fixed shaft 41 provides stable support for the rotating plate 42. When the sweeper needs to enter low areas such as under the bed or cabinet, the cylinder 441 in the push assembly 44 is driven to extend and retract, causing the sensor 442 at the output end to slide inside the sweeper body 1. When the sensor 442 moves, the connecting block 43 fixedly connected to the outside pulls the rotating plate 42 to rotate around the fixed shaft 41, ensuring that the sensor 442 slides down stably to adapt to the low environment. In addition, the anti-collision block 45 fixed on the push assembly 44 can also absorb external impacts and protect the inner sensor 442, ensuring that the sweeper can continuously and stably complete the cleaning work in complex environments.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
