Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning robots, specifically to a collision avoidance structure for cleaning robots. Background Technology
[0002] The anti-collision structure of a cleaning robot is a device that can avoid obstacles and collisions during the cleaning process, thereby maximizing work efficiency.
[0003] Cleaning robots combine artificial intelligence with the cleaning functions of ordinary vacuum cleaners to automatically clean floors. During cleaning, numerous obstacles (such as tables, chairs, walls, and pillars) are present on the floor. To reduce collision damage between the robot and these obstacles, anti-collision structures are typically installed. Multiple radar sensors around the robot detect these obstacles. However, because these sensors are evenly distributed around the robot, the detection area is mainly concentrated in the direction of movement, leaving other areas undetected. This results in wasted resources and inaccurate detection due to power outages or malfunctions. Consequently, the anti-collision protection is incomplete, impacting the robot's lifespan. Utility Model Content
[0004] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a collision avoidance structure for cleaning robots.

The anti-collision mechanism includes the robot body. The bottom of the robot is provided with several first rollers. The robot is equipped with radar and a motor. The motor is connected to a slide rod. The slide rod is provided with lead screws on both sides. The lead screws are located on the outside of the robot. The slide rod and the lead screws are provided with anti-collision blocks on the side away from the robot. The slide rod and the lead screws are provided with sliders. The middle part of the slider is provided with a rubber cylinder at the connection with the slide rod. The slider is provided with a horizontal plate and a vertical plate. The vertical plate is located on one side of the horizontal plate. The horizontal plate is provided with a groove. The groove is V-shaped.

Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.
[0024] First embodiment:
[0025] like Figure 1-6As shown, the anti-collision structure for the cleaning robot provided by this utility model includes: an anti-collision mechanism 100 and a protective mechanism 200. The protective mechanism 200 is located around the anti-collision mechanism 100. The anti-collision mechanism 100 includes a robot 101 body. The bottom of the robot 101 is provided with a plurality of first rollers 102. The robot 101 is equipped with a radar and a motor. The motor is connected to a slide rod 107. The slide rod 107 is provided with lead screws 106 on both sides. The lead screws 106 are located outside the robot 101. The slide rod 107 and the lead screws 106 are away from the robot 101. 01 has a bumper block 105 on one side, a slider 108 on the slide rod 107 and the lead screw 106, a rubber cylinder 110 at the connection between the middle of the slider 108 and the slide rod 107, a horizontal plate 109 and a vertical plate 112 inside the slider 108, the vertical plate 112 is located on one side of the horizontal plate 109, the horizontal plate 109 has a groove 111, the groove 111 is V-shaped, one end of the vertical plate 112 passes through the groove 111 and has a pin 113. In use, the robot 101 moves by the first roller 102 at the bottom. During the movement, if the robot... When robot 101 touches an object, anti-collision blocks 105 are installed around robot 101 to protect the robot body. When anti-collision blocks 105 touch an object, sensors on the anti-collision blocks 105 send commands to robot 101, causing the motor inside robot 101 to rotate. The motor drives the slide bar 107 to rotate, and the slide bar 107 drives the slider 108 to move on the slide bar 107 and the lead screw 106. When one side of the slider 108 contacts the anti-collision block 105, the horizontal plate 10 on the slider 108... 9. Due to the sliding effect of the pin 113, the horizontal plate 109 moves within the slider 108. The horizontal plate 109 moves away from the anti-collision block 105, so that the bottom end of the rubber cylinder 110 abuts against the anti-collision block 105. The rubber cylinder 110 is equipped with a sensor, which sends a sensor to the robot 101 body when the rubber cylinder 110 collides with the anti-collision block 105, so that the motor drives the slide bar 107 to rotate in the opposite direction, thereby causing the slider 108 to retract, so that the robot 101 body will not touch the object, thus protecting the robot 101 body.
[0026] The sensor causes the slider 107 to rotate, which in turn moves the rubber cylinder 110 forward until it touches the anti-collision block 105. Then, the sensor on the rubber cylinder 110 sends a command to make the slider 108 and the robot 101 body retract, preventing the robot 101 body from colliding with the object, increasing the robot's anti-collision probability, protecting the robot itself, and extending the robot's service life.
[0027] Second embodiment:
[0028] like Figure 4As shown, a round cap 114 is provided at one end of the pin 113 and the groove 111. The round cap 114 is engaged with the groove 111. When the pin 113 slides in the groove 111, the round cap 114 on one side of the pin 113 limits the pin 113, so that the pin 113 is always engaged with one end of the groove 111 through the round cap 114.
[0029] By setting a round cap 114 on one side of the pin 113, the movement trajectory of the pin 113 is fixed, thereby improving the stability of the device.
[0030] Third embodiment:
[0031] like Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the protective mechanism 200 includes a mounting plate 201 located on the outer wall of the robot 101. The top of the mounting plate 201 has a sliding groove 202, and one side of the mounting plate 201 has a first arc-shaped elastic component 204. The first arc-shaped elastic component 204 includes a connecting groove 206, which has two locations. A second roller 208 is installed within the connecting groove 206, and the connecting groove 206 is slidably connected to the sliding groove 202 via the second roller 208. An arc-shaped elastic block 207 is provided on the outer side of the connecting groove 206. The first arc-shaped elastic component 204 is located at the bottom of the anti-collision block 105. When the anti-collision block 105 collides with an object, the arc-shaped elastic block 207 at the bottom is also squeezed by the object. The arc-shaped elastic block 207 is squeezed by the object, causing the connecting grooves 206 on both sides to slide on the slide groove 202 through the second roller 208. The arc-shaped elastic block 207 is made of rubber. The arc-shaped elastic block 207 is deformed by the pressure of the object, thereby buffering the robot 101 and changing its movement trajectory, thus avoiding the object in front.
[0032] By setting a first arc-shaped elastic component 204 at the bottom of the anti-collision block 105, the arc-shaped elastic block 207 is deformed by the pressure of the object, which buffers the robot 101 body and changes the robot 101's movement trajectory, preventing it from continuing to collide with the object, thereby enhancing the adaptability and flexibility of the robot 101.
[0033] Fourth embodiment:
[0034] like Figure 5 As shown, the slide 202 is provided with limiting plates 203 at both the front and rear ends. The limiting plates 203 limit the movement trajectory of the connecting grooves 206 on both sides on the slide 202, preventing the connecting grooves 206 at both ends of the slide 202 from detaching.
[0035] Fifth embodiment:
[0036] like Figure 1 , Figure 2As shown, the first roller 102 is equipped with a telescopic rod 103, and the telescopic rod 103 is equipped with a spring 104. When the robot 101 moves, the road surface may be uneven. In this way, the telescopic rod 103 extends and retracts to compress the rebound spring 104, ensuring that the first roller 102 is always in contact with the ground and that the equipment will not tilt during movement.
[0037] In use, the robot 101 moves via the first roller 102 at its bottom. During movement, if the robot 101 touches an object, anti-collision blocks 105 are installed around the robot 101 to protect the robot body. When the anti-collision block 105 touches an object, a sensor on the anti-collision block 105 sends a command to the robot 101, causing the motor inside the robot 101 to rotate. The motor drives the slide bar 107 to rotate, and the slide bar 107 drives the slider 108 to move on the slide bar 107 and the lead screw 106. When one side of the slider 108 contacts the anti-collision block 105, the horizontal plate 109 on the slider 108 is affected by the sliding of the pin 113, causing the horizontal plate 109 to move within the slider 108. The horizontal plate 109 moves away from the anti-collision block 105, so that the bottom end of the rubber cylinder 110 abuts against the anti-collision block 105. The rubber cylinder 110 is equipped with... A sensor sends a signal to the robot 101 when the rubber cylinder 110 collides with the anti-collision block 105, causing the motor to drive the slide bar 107 to rotate in the opposite direction, thereby causing the slider 108 to retract and preventing the robot 101 from touching the object, thus protecting the robot 101. The first arc-shaped elastic component 204 is located at the bottom of the anti-collision block 105. When the anti-collision block 105 collides with the object, the arc-shaped elastic block 207 at the bottom is also squeezed by the object. The arc-shaped elastic block 207 is squeezed by the object, causing the connecting grooves 206 on both sides to slide on the slide groove 202 through the second roller 208. The arc-shaped elastic block 207 is made of rubber. The arc-shaped elastic block 207 is deformed by the pressure of the object, thereby buffering the robot 101 and changing its movement trajectory, avoiding it from the object in front, preventing it from continuing to collide with the object, and enhancing the adaptability and flexibility of the robot 101.
[0038] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
