Description

Technical Field

[0001] The utility model relates to the technical field of sweeping robots, in particular to a protective structure of the sweeping robot. Background Art

[0002] A sweeping robot, also known as an automatic cleaning machine, smart vacuum cleaner, robot vacuum cleaner, etc., is a type of smart home appliance that can automatically complete floor cleaning in the room with a certain degree of artificial intelligence. It generally uses brushing and vacuuming to absorb debris on the ground into its own garbage storage box, thereby completing the function of floor cleaning.

[0003] At present, the existing sweeping robots need to autonomously find their way to sweep the floor during their work. Due to the limited sensitivity of the laser radar or infrared sensor installed inside, they often collide with tables, chairs or other objects in the home actively or passively. In addition, since the body of the sweeping robot is made of plastic, if the collision force is large, it will cause the body of the sweeping robot to break, or even directly cause damage to the sweeping robot. Replacing the sweeping robot will cost material and financial resources. For this reason, we propose a protective structure for the sweeping robot to solve the above problems. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 , the protective structure of the sweeping robot, the protective structure of the sweeping robot, includes a sweeping robot body 1, four groups of rubber plates 2 are distributed on the outside of the sweeping robot body 1, and the inner side of each group of rubber plates 2 is symmetrically connected with a connecting rod 3, the sweeping robot body 1 can be controlled by a mobile phone, so as to realize intelligent cleaning of the ground. The specific control principle is the existing technology and will not be described in detail here. The other end of the connecting rod 3 is connected to a connecting block 4, and a connecting groove 5 adapted to the connecting block 4 is opened at the top of the sweeping robot body 1, and a spring 6 is connected to the inner wall of the connecting groove 5, and the other end of the spring 6 is fixedly connected to the connecting block 4.

[0023] Further, see Figure 1 , Figure 2 and Figure 3 It can be seen that grooves are evenly opened on the outer side of the rubber plate 2, and balls 15 are installed inside the grooves. By setting multiple groups of balls 15, sliding friction can be converted into rolling friction. When the balls 15 collide with foreign objects, they can drive the balls 15 to rotate to further buffer the impact force.

[0024] Further, see Figure 2 It can be known that four groups of static contacts 14 are symmetrically embedded inside the sweeping robot body 1, and a moving contact 13 is embedded on the inner side of the rubber plate 2 at a position corresponding to the static contact 14. The moving contact 13 is fixedly installed on the inner side of the rubber plate 2, and the static contact 14 is fixedly installed inside the sweeping robot body 1. A touch alarm and a signal sensor are installed inside the sweeping robot body 1, which are not shown in the figure. The basic principle of the two is to convert the touch signal into an alarm signal through a circuit. When the moving contact 13 and the static contact 14 are in contact with each other, the signal sensor is triggered by the touch mechanism, so that the alarm signal can be transmitted to the user's mobile phone. This is an existing mature technical means, and the specific principle will not be described in detail here.

[0025] Further, see Figure 3 and Figure 4It can be known that a docking groove 8 matched with the connecting rod 3 is opened inside the rubber plate 2, and a threaded groove is opened inside the rubber plate 2 above the docking groove 8, a threaded rod 10 is inserted inside the threaded groove, and a connecting plate 11 is connected to the top of the threaded rod 10, and a card slot matched with the threaded rod 10 is opened inside the connecting rod 3. When in use, the card slots opened inside the threaded rod 10 and the connecting rod 3 can facilitate the user to remove the severely deformed rubber plate 2 from the periphery of the sweeping robot body 1 for replacement, so as to ensure the protective effect of the sweeping robot body 1.

[0026] Further, see Figure 4 It can be known that two sets of rubber rings 9 are sleeved on the end of the connecting rod 3, and the outer side of the rubber ring 9 fits with the inner wall of the docking groove 8. When installing a new set of rubber plates 2, the user can first sleeve the docking groove 8 opened inside it on the outer periphery of the connecting rod 3. The rubber ring 9 sleeved on the end of the connecting rod 3 can be used to pre-position the sleeved rubber plate 2, so that the staff can subsequently rotate the connecting disk 11 to insert the threaded rod 10 into the slot inside the connecting rod 3.

[0027] Further, see Figure 4 It can be known that the top of the connecting disk 11 is connected to a rotating block 12, and the rotating block 12 is set as a columnar structure. The rotating block 12 set by the columnar structure can facilitate the staff to rotate the connecting disk 11, thereby effectively improving the convenience of using the device.

[0028] Further, see Figure 3 It can be known that a movable groove is opened inside the connecting block 4, and a guide rod 7 is inserted inside the movable groove. The two ends of the guide rod 7 are connected to the inner wall of the connecting groove 5. Through the mutual cooperation of the movable groove and the guide rod 7, the connecting block 4 inside the connecting groove 5 can be guided to effectively prevent the spring 6 from being skewed, thereby effectively ensuring the service life of the spring 6.

[0029] Working principle: When using the utility model, the user can first place the sweeping robot body 1 at home, and use the mobile phone to make it intelligently clean the floor at home. When the sweeping robot body 1 collides with foreign objects during operation, the impact force will first act on the rubber plate 2 arranged on the periphery of the sweeping robot body 1, and the rubber plate 2 transmits the impact force to the connecting rod 3, thereby driving the connecting block 4 connected to its end to slide inside the connecting groove 5, and compressing the spring 6 connected to the inner wall of the connecting groove 5. The elastic characteristics of the spring 6 itself can buffer the impact force. When the impact force on the rubber plate 2 is large, it will drive the moving contact 13 and the static contact 14 distributed on the inner side thereof to move. When the rubber sheet 2 is deformed or damaged, the user can manually rotate the rotating block 12 to drive the threaded rod 10 to rotate at the same time and pull it out from the slot inside the connecting rod 3. At this time, the user can push the rubber sheet 2 to separate it from the connecting rod 3. At this time, the user can put a new set of rubber sheets 2 on the connecting rod 3, and then rotate the rotating block 12 in the opposite direction to make the threaded rod 10 engage with the slot opened in the connecting rod 3, and realize the replacement operation of the rubber sheet 2. The above is the entire working principle of the utility model.

[0030] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
