Description

Technical Field

[0001] The utility model relates to the technical field of window cleaning machines, in particular to a crawler structure of a window cleaning machine. Background Art

[0002] An intelligent window cleaning machine, also known as a window cleaning robot, a glass cleaning robot, an intelligent window cleaner, an intelligent window cleaner, etc., is a kind of intelligent household appliance. It can firmly adsorb on the glass by virtue of a vacuum pump or a blower device at its bottom, and then uses the force of its adsorption on the glass to drive a rag at the bottom of the body to wipe off the dirt on the glass.

[0003] The window cleaning machines in the prior art rely on the vacuum effect to adsorb on the surface of the outer window or the outer wall, and use crawlers to walk. The commonly used crawlers are flat crawlers or one - character crawlers. When the water vapor is large, they are prone to slipping, resulting in the equipment being unable to walk normally. Based on this, a crawler structure of a window cleaning machine is provided. Summary of the Invention

[0004] The purpose of the utility model is to provide a crawler structure of a window cleaning machine to solve the problems in the above background.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A crawler structure of a window cleaning machine, including a crawler assembly installed inside the main body of the window cleaning machine and protruding from the bottom of the main body of the window cleaning machine. The crawler assembly includes a fixed housing, a driving synchronous pulley, a driven synchronous pulley, a belt, and a tensioning idler pulley.

[0006] The fixed housing is installed inside the main body of the window cleaning machine. The driving synchronous pulley and the driven synchronous pulley are horizontally distributed inside the fixed housing and are rotatably connected to the fixed housing. The belt is sleeved inside the driving synchronous pulley and the driven synchronous pulley. The bottom of the belt protrudes outside the fixed housing and extends to the bottom of the main body of the window cleaning machine.

[0007] The tensioning idler pulley is rotatably connected inside the fixed housing and is located below the middle of the driving synchronous pulley and the driven synchronous pulley. The tensioning idler pulley meshes with the tooth groove part at the bottom inside of the belt. The tensioning idler pulley is used to increase the tension of the belt, thereby increasing the friction between the belt and the wall or the window.

[0008] As a further scheme of the utility model: The crawler assembly further includes a driving motor and a planetary worm and worm gear reducer.

[0009] The driving motor and the planetary worm and worm gear reducer are fixed on one side outside the fixed housing, and the output end of the planetary worm and worm gear reducer is connected to the central shaft of the driving synchronous pulley. The output end of the driving motor is connected to the input end of the planetary worm and worm gear reducer.

[0010] When the driving motor runs, the low-speed rotation of the driving synchronous pulley can be realized through the transmission of the planetary worm and worm reducer.

[0011] As a further solution of the present utility model: Several water grooves are formed on the surface of the belt and are evenly distributed along the track of the outer wall of the belt.

[0012] As a further solution of the present utility model: The fixed housing is composed of two cover shells, and first positioning cylinder columns for providing positioning installation and rotational support for the driving synchronous pulley and the driven synchronous pulley are formed on the inner sides of the two cover shells. The driving synchronous pulley and the driven synchronous pulley are rotatably sleeved on the first positioning cylinder columns, and the output end of the planetary worm and worm reducer penetrates through the middle of one first positioning cylinder column and is connected to the central axis of the driving synchronous pulley;

[0013] Second positioning cylinder columns for positioning installation and rotational support of the tension idler are also formed on the inner sides of the two cover shells, and the rotating shaft of the tension idler is rotatably connected to the inner side of the second positioning cylinder column.

[0014] As a further solution of the present utility model: Docking cylinder columns that are sleeved with each other are formed in the middle of the inner sides of the two cover shells for realizing the positioning splicing of the two cover shells.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] By adding a tension idler between the driving synchronous pulley and the driven synchronous pulley, the tension of the belt can be improved, making the belt tighter, so that the belt closely adheres to the wall surface or the window surface, thereby achieving the effect of increasing the friction between the belt and the wall or the window. In addition, the water grooves provided on the surface of the belt can be used to drain water vapor, reducing the probability of slipping and further improving the running stability of the crawler assembly.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a crawler structure of a window cleaning machine includes a crawler assembly 2 installed inside the main body 1 of the window cleaning machine and protruding from the bottom of the main body 1 of the window cleaning machine. The crawler assembly 2 includes a fixed outer shell 201, a driving synchronous pulley 202, a driven synchronous pulley 203, a belt 204, and a tensioning idler pulley 205;

[0024] The fixed outer shell 201 is installed inside the main body 1 of the window cleaning machine. The driving synchronous pulley 202 and the driven synchronous pulley 203 are horizontally distributed inside the fixed outer shell 201 and are rotatably connected to the fixed outer shell 201. The belt 204 is sleeved inside the driving synchronous pulley 202 and the driven synchronous pulley 203. The bottom of the belt 204 protrudes outside the fixed outer shell 201 and extends to the bottom of the main body 1 of the window cleaning machine;

[0025] The tensioning idler pulley 205 is rotatably connected inside the fixed outer shell 201 and is located below the middle of the driving synchronous pulley 202 and the driven synchronous pulley 203. The tensioning idler pulley 205 meshes with the inner bottom tooth groove part of the belt 204. The tensioning idler pulley 205 is used to increase the tension of the belt 204, thereby increasing the friction between the belt 204 and the wall or the window;

[0026] The crawler assembly 2 further includes a driving motor 207 and a planetary worm and worm gear reducer 208;

[0027] The driving motor 207 and the planetary worm and worm gear reducer 208 are fixed on one side outside the fixed outer shell 201, and the output end of the planetary worm and worm gear reducer 208 is connected to the central axis of the driving synchronous pulley 202, and the output end of the driving motor 207 is connected to the input end of the planetary worm and worm gear reducer 208;

[0028] When the drive motor 207 operates, the low-speed rotation of the driving synchronous pulley 202 can be achieved through the transmission of the planetary worm gear reducer 208;

[0029] Several water grooves 206 are formed on the surface of the belt 204 and are evenly distributed along the outer wall track of the belt 204.

[0030] In this embodiment: It should be noted that a vacuum adsorption component 3 and a rolling wiping component 4 extending to the bottom of the window inserting machine main body 1 are arranged inside the window inserting machine main body 1, and a nozzle component 5 is installed at the front end in the moving direction of the window inserting machine main body 1. Among them, the vacuum adsorption component 3 is located in the middle of the bottom of the window inserting machine main body 1, and two sets of track components 2 and rolling wiping components 4 are arranged and symmetrically distributed with the vacuum adsorption component 3 as the center. When the window inserting machine main body 1 is in use, it is adsorbed on the wall surface or the glass window through the vacuum adsorption component 3, moves through the track component 2, sprays the cleaning liquid through the nozzle component 5, and realizes the cleaning operation through the rolling wiping component 4, so as to realize the wiping function of the wiping machine main body 1 (the vacuum adsorption component 3, the rolling wiping component 4, and the nozzle component 5 are all conventional structures of existing wiping machines);

[0031] When the track component 2 operates, by starting the drive motor 207, the low-speed rotation of the driving synchronous pulley 202 can be achieved through the transmission of the planetary worm gear reducer 208. The driving synchronous pulley 202 drives the belt 204 to run, and the driven synchronous pulley 203 and the tension idler pulley 205 are driven to rotate by the belt 204. By adding the idler tension idler pulley 205 between the driving synchronous pulley 202 and the driven synchronous pulley 203, the tension of the belt 204 can be increased, making the belt 204 tighter, so as to make the belt 204 closely fit the wall surface or the window surface, and then achieve the effect of increasing the friction between the belt 204 and the wall surface or the window;

[0032] In addition, the water grooves 206 arranged on the surface of the belt 204 can be used to drain water vapor, reduce the probability of slipping, and further improve the stability of the movement of the track component 2.

[0033] Please refer to Figures 2 to 4 , the fixed housing 201 is composed of two housing shells, and a first positioning cylinder column 209 for positioning, installing and rotationally supporting the driving synchronous pulley 202 and the driven synchronous pulley 203 is formed on the inner side of the two housing shells. The driving synchronous pulley 202 and the driven synchronous pulley 203 are rotationally sleeved on the first positioning cylinder column 209, and the output end of the planetary worm gear reducer 208 penetrates through the middle of a first positioning cylinder column 209 and is connected to the central axis of the driving synchronous pulley 202;

[0034] A second positioning cylinder column 210 for positioning, installing and rotationally supporting the tension idler pulley 205 is also formed on the inner side of the two housing shells, and the rotating shaft of the tension idler pulley 205 is rotationally connected to the inner side of the second positioning cylinder column 210;

[0035] In the middle of the inner sides of the two housing covers, there are formed docking cylinder columns 211 sleeved with each other for realizing the positioning and splicing of the two housing covers.

[0036] In this embodiment: through the setting of the docking cylinder column 211, the fixed outer shell 201 can drive the positioning and assembly. At the same time, through the cooperation of the first positioning cylinder column 209 and the second positioning cylinder column 210, the positioning installation of the driving synchronous pulley 202, the driven synchronous pulley 203 and the tensioning idler pulley 205 can be realized, which not only makes the assembly of the crawler assembly 2 more convenient, but also ensures the stable rotation of the driving synchronous pulley 202, the driven synchronous pulley 203 and the tensioning idler pulley 205.

[0037] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
