For example, "connection" may be a fixed connection, a detachable connection, or a unitary construction; it may be a mechanical connection, or an electrical connection; it may be a direct connection, or an indirect connection through an intermediary, or two devices, elements or Internal connectivity between components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

With the improvement of people's living standards, more and more families begin to use cleaning equipment for auxiliary cleaning to reduce labor intensity and improve the quality of life. Commonly used cleaning equipment includes sweeping robots and window cleaning robots.

At present, most of the mobile cleaning equipment (for example, a sweeping robot, a window cleaning robot, etc.) have a traveling mechanism, and the traveling mechanism may be a wheel-type structure or a crawler-type structure. Regardless of the specific structure of the traveling mechanism, some components (ie, the moving surface) must be in contact with the surface to be cleaned, so as to drive the cleaning equipment to move on the surface to be cleaned through the frictional force generated between the moving surface and the surface to be cleaned.

For the convenience of description, the mobile cleaning equipment is taken as an example of a window cleaning robot. The window cleaning robot uses a walking synchronous belt assembly as a walking mechanism (because the walking synchronous belt assembly integrates the advantages of chain drive, belt drive and gear drive. , has the advantages of accurate transmission, low noise, stable contact and large friction driving force, so it is widely used). When the synchronous belt assembly is used, the inner side of the synchronous belt is used as the driving surface, the driving surface transmits power by engaging with the pulley, the outer side of the synchronous belt is used as the moving surface, and the moving surface is in contact with the glass surface. The friction between the contact with the glass surface can move on the glass surface. Therefore, the friction performance of the moving surface is also the core performance of the synchronous belt.

Due to the presence of dust particles on the glass surface, when the window cleaning robot cleans the glass surface, the moving surface needs to be in contact with the glass surface, so it is difficult to avoid dust particles on the moving surface. The dust adhering to the moving surface will cause the friction performance of the moving surface to decrease, which will affect the mobility of the window cleaning robot, and may cause slippage, deviation and other undesirable motion phenomena, which will eventually lead to poor window cleaning effect.

In the prior art, in order to ensure the friction performance between the moving surface of the traveling mechanism and the glass surface, the traditional method is to use an alarm prompt or an explanation in the instruction manual to guide the user to clean the moving surface at regular intervals, so as to avoid rubbing. During the use of the window robot, phenomena such as slippage and deviation occur.

The above-mentioned method of user cleaning solves the problem of decreased friction performance between the moving surface and the glass surface, but it also causes the window cleaning robot to rely on the user to regularly clean the moving surface in order to continue to work, which also increases the use of users. burden and affect the user experience. In addition, to clean the moving surface by the user, the window cleaning robot needs to be removed from the glass surface, which increases the original working time of the window cleaning robot and reduces the working efficiency of the window cleaning robot. At the same time, after the user cleans the moving surface, the user needs to put the window-cleaning robot back on the glass surface. In this scenario, the pick-and-place positions of the window-cleaning robot usually cannot be exactly coincident, which leads to the possibility of cleaning omissions for the window-cleaning robot. area, which affects the cleaning effect.

Therefore, how to improve the structure of the mobile cleaning equipment so that the mobile cleaning equipment can still run smoothly on the working plane without the need for the user to clean the moving surface has become an urgent problem to be solved in the art.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in the present application are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

Please refer to FIG. 1 , FIG. 2 and FIG. 3 together. In an achievable embodiment, the mobile device at least includes a body 1 , a traveling mechanism 2 and a cleaning assembly 3 , wherein the traveling mechanism 2 is connected to the body 1 , The cleaning assembly 3 is connected with the body 1 or with the running gear 2 . The traveling mechanism 2 has a moving surface 21 , and the traveling mechanism 2 can contact the working plane 4 through the moving surface 21 , thereby driving the body 1 to move on the working plane 4 . In other words, since the moving surface 21 is in contact with the working plane 4, and there is friction between the moving surface 21 and the working plane 4 (when the moving surface 21 is in contact with the working plane 4, there is a friction between the moving surface 21 and the working plane 4). Static friction force, when the moving surface 21 slides relative to the working plane 4, a dynamic friction force is generated along the tangential direction of the contact surface). Therefore, when the traveling mechanism 2 drives the moving surface 21 to move, the traveling mechanism 2 is displaced relative to the working plane 4 , and further, the body 1 can move on the working plane 4 .

The moving surface 21 has a non-contact area 211 that is not in contact with the working plane 4 . In other words, when the mobile device is placed on the work plane 4, no matter whether the mobile plane 21 is in a static state or a motion state, there will be an area on the mobile surface 21 that does not contact the work plane 4, and this area is the subject of the present application. Defined non-contact area 211 . That is to say, the non-contact area 211 is defined based on the area where the moving surface 21 is in contact with the working plane 4. No matter what time the moving surface 21 is at, the area in contact with the working plane 4 is removed from the moving surface 21, which is Non-contact area 211 .

When the traveling mechanism 2 drives the moving surface 21 to move, the cleaning assembly 3 cleans the non-contact area 211 . When the moving surface 21 moves, since the non-contact area 211 on the moving surface 21 is constantly changing, the cleaning component 3 cleans the non-contact area 211 , that is, the cleaning component 3 can clean the entire moving surface 21 .

It is worth mentioning that "when the traveling mechanism 2 drives the moving surface 21 to move, the cleaning component 3 cleans the non-contact area 211" defined in this application may mean that when the traveling mechanism 2 drives the moving surface 21 to move, The cleaning assembly 3 may be in a state of cleaning the non-contact area 211 all the time; of course, it may also mean that when the walking mechanism 2 drives the moving surface 21 to move, the cleaning assembly 3 may be in a state of not cleaning the non-contact area 211 . That is to say, there are two scenarios for the setting of the cleaning component 3, one scenario is: the cleaning component 3 is always in contact with the non-contact area 211, and the other scenario is: the cleaning component 3 can be in contact with the non-contact area 211. 211 In the two states of contact or non-contact, the conversion is performed.

In an achievable embodiment, the cleaning assembly 3 can be connected with the body 1 , that is, the cleaning assembly 3 is fixed on the body 1 . In another achievable embodiment, the cleaning assembly 3 can also be connected to the traveling mechanism 2 , that is, the cleaning assembly 3 is fixed on the traveling mechanism 2 . The present application utilizes the characteristic that the non-contact area 211 changes cyclically when the moving surface 21 moves, and the non-contact area 211 is cleaned by the cleaning component 3 , thereby realizing the cleaning of the entire moving surface 21 .

It should be specially pointed out that the cleaning assembly 3 is detachably connected to the body 1 or the running mechanism 2 . For example, in a working environment with a lot of dust, the cleaning component 3 can be installed on the mobile device for use, and in a working environment with less dust, the cleaning component 3 can be detached from the mobile device to improve the performance of the mobile device. flexibility of use.

When the cleaning assembly 3 is installed on the mobile device, as to when the cleaning assembly 3 can clean the moving surface 21, in an achievable embodiment, when the body 1 moves on the working plane 4, the cleaning assembly 3 Contact with the non-contact area 211, so that the cleaning assembly 3 can clean the moving surface 21; in another achievable embodiment, the cleaning assembly can also be performed when the body 1 is suspended and the moving surface 21 is suspended. 3 is in contact with the moving surface 21 , so that the cleaning assembly 3 can clean the moving surface 21 .

In practical applications, the body 1 can be designed with an integral structure. In addition, in order to facilitate the installation of components inside the mobile device, the body 1 may also adopt a split structure design. Specifically, the body 1 may include a lower casing 11 and an upper casing 12, and the lower casing 11 and the upper casing 12 may be mutually Card access.

The moving surface 21 is used as the walking part of the walking mechanism 2 , and the structural form of the moving surface 21 can be set according to the specific structure of the walking mechanism 2 . In practical applications, the traveling mechanism 2 can have various structures, such as a crawler-type structure, a synchronous belt-type structure, a traveling wheel-type structure, and a ball-type structure, etc., wherein, when the traveling mechanism 2 is a crawler-type structure, the moving surface 21 is the outer surface of the crawler; when the traveling mechanism 2 is a synchronous belt structure, the moving surface 21 is the outer surface of the synchronous belt; when the traveling mechanism 2 is a traveling wheel structure, the moving surface 21 is the outer surface of the traveling wheel; When the traveling wheel mechanism 2 is a spherical structure, the moving surface 21 is an outer spherical surface of a sphere.

Regarding the connection form of the traveling mechanism 2 and the above-mentioned body 1, in an achievable embodiment, the number of the traveling mechanism 2 can be set to two, and the above-mentioned two traveling mechanisms 2 are symmetrically arranged on two sides of the bottom surface of the above-mentioned lower casing 11. side, so that the body 1 can move smoothly. In another achievable implementation manner, the number of running mechanisms 2 may also be set to one or more than two, and the present application does not limit the number of running mechanisms 2 .

It should be particularly pointed out that the working plane 4 defined in this application is the plane on which the mobile device works, such as a glass surface, a wall, and a floor. The specific form of the mobile device may be a cleaning robot, a floor washing machine, a window cleaning robot, etc., which is not limited in this application.

For the specific structure of the above cleaning assembly 3 , please refer to FIG. 2 and FIG. 4 together. In an achievable embodiment, the cleaning assembly 3 at least includes a cleaning head 31 and a mounting seat 32 . The cleaning head 31 is connected to the mounting seat 32, and the mounting seat 32 is detachably connected to the body 1 or the walking mechanism 2. The mounting seat 32 is used to fix the cleaning head 31, so that the cleaning head 31 can be fixed by the mounting seat 32 On the body 1 or the running gear 2. In practical applications, the cleaning head 31 may adopt a brush structure, and when the moving surface 21 moves, the above-mentioned bristles can clean the dust attached to the moving surface 21 . In another achievable embodiment, the cleaning head 31 can also adopt a scraping strip structure, and when the moving surface 21 moves, the scraping strip can scrape off the dust adhering to the moving surface 21 .

Further, as shown in FIG. 5 , a contact portion 5 may exist between the cleaning head 31 and the moving surface 21 . Specifically, when the cleaning head 31 is in contact with the moving surface 21 , there may be a mutual contact area between the cleaning head 31 and the moving surface 21 , and this area is the contact portion 5 . The cleaning head 31 can clean the moving surface 21 by cleaning the contact portion 5 . It should be specially pointed out that with the movement of the moving surface 21, the area covered by the contact portion 5 on the moving surface 21 is constantly changing, and finally the area covered by the contact portion 5 may include the entire moving surface 21. In this way, the cleaning head 31 The entire moving surface 21 can be cleaned, which also makes it unnecessary for the user to manually clean the moving surface 21 to remove dust adhering to the moving surface 21, thereby reducing the burden on the user when using the device.

In practical applications, when the mobile device cleans the working plane 4, the mobile device usually needs to perform reciprocating movement, that is, the moving surface 21 needs to perform forward and reverse movements. In order to realize the forward movement of the moving surface 21 or the reverse movement, the cleaning head 31 can effectively clean the dust attached to the moving surface 21 , and the cleaning head 31 and the moving surface 21 may form a specific angle. In an achievable embodiment, referring specifically to FIG. 5 , there is a preset angle β between the normal line a of the moving surface 21 at the contact portion 5 and the central axis b of the cleaning head 31 , and the preset angle β It can be set according to the experience value.

Further, the preset included angle β can be set between 0° and 15°, so that the cleaning head 31 and the moving surface 21 are approaching a vertical contact state, so that no matter whether the moving surface 21 performs a forward motion or a reverse motion , the contact areas of the cleaning head 31 and the moving surface 21 are close to the same, and the frictional force generated by the cleaning head 31 to the moving surface 21 is also close to the same, so that the forward movement and the reverse movement of the moving surface 21 are affected by resistance is approaching the same. By setting the preset angle β between 0° and 15°, it can avoid the situation of multiple steps or missing steps during the movement of the moving surface 21, and ensure the smooth movement of the mobile device on the working plane 4. When the moving surface 21 moves forward and backward, the moving surface 21 is effectively cleaned.

In an achievable embodiment, please refer to FIG. 4 and FIG. 6 together, the cleaning head 31 may be composed of several bristle bundles 311 , and the mounting seat 32 is correspondingly provided with several mounting holes 321 . In other words, the number of the mounting holes 321 on the mounting seat 31 is the same as the number of the bristle bundles 311 , and each of the mounting holes 321 is respectively connected with a bristle bundle 311 . Specifically, one end of the bristle bundle 311 is located in the mounting hole 321 , and at least part of the bristle bundle 311 is exposed in the mounting hole 321 , so that the bristle bundle 311 exposed in the mounting hole 321 can clean the non-contact area 211 .

In practical applications, the bristle bundle 311 may be composed of a combination of several bristle filaments, and the bristle bundle 311 may be fixed in the mounting hole 321 through a flocking process, thereby forming the cleaning head 31 on the mounting seat 32 . The mounting hole 321 can be formed by opening a hole on the mounting seat 32 , so that the connection method of the bristle bundle 311 and the mounting seat 32 can be simplified, and the production process can be reduced.

Further, considering that the bristle bundle 311 should have sufficient toughness and durability, so as to avoid the bristle abrasion and breakage caused by the bristle filament often being in a bent state when the bristle bundle 311 cleans the moving surface 21, the bristle filament is PA material can be used.

In an achievable embodiment, when the cleaning assembly 3 cleans the moving surface 21, the distance between the mounting seat 32 and the moving surface 21 can be between 4 mm and 7 mm, so as to avoid excessively long free length of the bristle filaments. , causing the bristle bundle 311 to be too soft and affecting the cleaning effect. At the same time, the distance between the mounting base 32 and the moving surface 21 is between 4 mm and 7 mm, which can also prevent the bristle bundles 311 from wearing too hard on the moving surface 21 due to the short free length of the bristle filaments. Further, the amount of interference between the bristle filaments on the bristle bundle 311 and the moving surface 21 can be between 0.5 mm and 2 mm, so as to prevent the contact area between the bristle bundle 311 and the moving surface 21 from being too large, resulting in the bristle bundle 311 being too large. The frictional force with the moving surface 21 is too large, which eventually hinders the normal operation of the moving surface 21 . Further, the amount of interference between the bristle filaments on the bristle bundle 311 and the moving surface 21 can also be used in conjunction with the preset angle β, so that no matter the moving surface 21 moves forward or reversely, the bristle bundle 311 and The friction force generated between the moving surfaces 21 is the smallest, which not only reduces the obstruction of the bristle bundles 311 to the movement of the moving surfaces 21 , but also reduces the wear amount of the bristle bundles 311 .

In practical applications, in order to avoid a missed sweep area when the cleaning assembly 3 cleans the moving surface 21 , the bristle bundles 311 may have a specific arrangement. In an achievable embodiment, referring specifically to FIG. 7 , several mounting holes 321 have a preset arrangement. Through the above-mentioned preset arrangement, the projection of the cleaning head 31 on the length direction of the mounting seat 32 has no gap area, that is, the bristle bundle 311 completely covers the side of the mounting seat 32 with the mounting holes 321 . Further, each mounting hole 321 has a predetermined diameter, so that the total area of the plurality of mounting holes 321 satisfies a first preset value, wherein the specific value of the first preset value can be set according to an empirical value.

In practical applications, the preset arrangement can be logarithmic spiral arrangement, star arrangement, and rectangular array. Wherein, the diameter of the mounting hole 321 may be between 1mm-3mm. That is, the diameter of the bristle bundle 311 may be between 1mm-3mm, and the diameter of a single bristle filament may be between 0.08mm-1.5mm.

In an achievable embodiment, referring to FIG. 7 , the preset arrangement can be configured as follows: a plurality of installation holes 321 are arranged in at least two rows of installation areas, and the installation holes 321 in each installation area are arranged at intervals, adjacent to each other. The installation holes 321 in the two rows of installation areas are arranged staggered in sequence, and two adjacent installation holes 321 are arranged to overlap each other. The installation holes 321 in each installation area are arranged at intervals, and installation gaps can be reserved around the installation holes 321 to facilitate subsequent installation of the bristle bundles 311 on the installation holes 321 . The installation holes 321 in the installation areas of two adjacent rows are arranged alternately and overlappingly, so that there is no gap area in the projection of the cleaning head 31 in the length direction of the installation seat 32. In this way, when the cleaning head 31 cleans the moving surface 21, there will be no gaps. The missed scanning area ensures the cleaning effect of the cleaning head 31 on the moving surface 21 .

Further, in an achievable embodiment, the width of the contact portion 5 is greater than or equal to the width of the moving surface 21, and the ratio of the first preset value to the area of the contact portion 5 satisfies a prescribed value, and the prescribed value may be located at 1.20. Between -1.60. In other words, the total area of the mounting holes 321 should be larger than the area of the contact portion 5 (ie, the area where the cleaning head 31 and the moving surface 21 are in contact with each other). Since one end of the bristle bundle 311 is installed in the mounting hole 321 , the total area of the several bristle bundles 311 will also be larger than the area of the contact portion 5 , which means that the cleaning area of the cleaning head 31 will be larger than that of the contact portion 5 . In this way, the cleaning head 31 can completely cover the contact portion 5, and when the moving surface 21 passes the cleaning head 31, there will be no area on the moving surface 21 that the cleaning head 31 cannot clean, thereby ensuring the cleaning effect of the cleaning head 31 on the moving surface 21 . 8 is a schematic diagram of the moving surface 21 passing through the cleaning assembly 3 when the moving surface 21 moves. The area covered by the shadow in the figure can be regarded as the area of the contact portion 5 .

In order to facilitate the replacement and disassembly of the cleaning assembly 3 on the mobile device, the cleaning assembly 3 can be detachably connected to the body 1 or the running mechanism 2 through a connecting assembly. For the fixing method of the cleaning assembly 3, the present application takes the connection of the cleaning assembly 3 to the body 1 as an example, and uses four embodiments for description:

In the first achievable embodiment, please refer to FIG. 9 and FIG. 10 together, the cleaning assembly 3 may be connected to the body 1 by means of screw connection. Specifically, the mobile device may further include a first locking screw 6, wherein the body 1 has a first threaded hole 13, and the mounting base 32 has a connecting through hole 322, wherein the first threaded hole 13 corresponds to the connecting through hole 322 It is arranged so that when the mounting seat 32 is docked with the body 1, the first threaded hole 13 can communicate with the connecting through hole 322; The mounting seat 32 is fixed on the body 1 , so that the cleaning assembly 3 can be fixed on the body 1 .

In this embodiment, in order to ensure the stability of the connection between the mounting seat 32 and the body 1 . At least two of the first locking screw 6, the first threaded hole 13 and the connecting through hole 322 can be used. In this way, when the mounting seat 32 is connected to the body 1, the mounting seat 32 will not rotate relative to the body 1, and the mounting seat 32 will not rotate relative to the body 1. 32 is fixed more stable. In addition, when the mounting seat 32 is connected to the body 1 , the first threaded hole 13 and the connecting through hole 322 can be coaxially arranged, so that the first locking screw 6 can be threadedly connected to the first threaded hole 13 through the connecting through hole 322 .

In practical applications, the first threaded hole 13 can be integrally formed with the body 1. For example, when the body 1 is injection-molded, a thread forming structure is provided in the mold, so that the first threaded hole is formed while the body 1 is being formed. 13. Correspondingly, the connecting through hole 322 may be integrally formed with the mounting seat 32 , or the mounting seat 32 may be opened after the mounting seat 32 is formed.

In the second achievable embodiment, please refer to FIG. 11 , FIG. 12 , FIG. 13 , FIG. 14 and FIG. 15 together, the cleaning assembly 3 can be connected to the body 1 by means of snap connection. Specifically, the mobile device further includes a snap seat 7 , the snap seat 7 is provided on the body 1 , and a snap slot 71 is provided on the snap seat 7 ; a slide slot 323 is provided in the mounting seat 32 , and the slide slot 323 The side is provided with a clamping block 324 ; when the mounting seat 32 is docked with the body 1 through the sliding groove 323 , the clamping block 324 can be clamped with the clamping groove 71 , so that the mounting base 32 is fixed on the clamping base 7 .

In this embodiment, the locking block 324 may be an elastic bump, and the elastic bump protrudes outward from the inner side surface of the sliding groove 323 . In this way, when the mounting seat 32 slides along the engaging seat 7 , the elastic blocking block 324 can enter into the engaging groove 71 by using its own deformability, so that the mounting seat 32 can The mounting seat 32 is fixed on the body 1 by being fixed on the clamping seat 7 .

It should be pointed out that the clamping block 324 can also be a telescopic protrusion. When the mounting base 32 slides along the clamping base 7, the clamping block 324 is in a retracted state. The clamping block 324 protrudes and is clamped in the clamping slot 71 , so that the mounting base 32 can be fixed on the clamping base 7 .

The clamping block 324 may also have no deformability, that is, the clamping block 324 is a rigid structure. At this time, the clamping block 324 can protrude from the inner side of the sliding groove 323. Accordingly, the mounting seat 32 has appropriate deformation ability.
