Description

Technical Field

[0001] The utility model relates to the technical field of floor scrubbers, in particular to a full-aluminum structure of a main frame of a floor scrubber. Background Art

[0002] A floor scrubber is a type of cleaning equipment suitable for a variety of floors. Its main operating modes are hand-push and ride-on. The entire machine is driven by a battery DC and efficiently cleans the floor through the front and rear disc brushes and squeegee operations.

[0003] Existing floor scrubbers typically have anti-collision wheels installed on the sides of the brush disc at the front of the machine. These wheels provide some protection against side impacts. However, in confined spaces or environments with numerous obstacles, the likelihood of a head-on collision increases significantly, and the limitations of these wheels become apparent. In the event of a head-on collision, the side anti-collision wheels are ineffective, and the entire impact force falls entirely on the brush disc, which can easily cause damage. In light of this, we propose an all-aluminum structure for the main frame of a floor scrubber. Utility Model Content

[0024] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0025] Example: A full aluminum structure of the main frame of a floor scrubber, see Figures 1 to 5 , including a brush disc main frame 1 arranged at the bottom of the floor scrubber body, the brush disc main frame 1 includes a brush disc cover 2, the top of the brush disc cover 2 is a symmetrical structure fixedly connected to two connecting arms 3, the terminal ends of the connecting arms 3 are fixedly connected to the bottom of the floor scrubber body, and the two connecting arms 3 are fixedly supported by at least one set of cross frames 4. A squeegee 5 is arranged on one side of the circumference of the brush disc cover 2, and the squeegee 5 is fixedly connected to the brush disc cover 2 through a connecting frame 6. A motor 7 is fixedly installed on the upper surface of the brush disc cover 2, and a brush disc 8 is movably installed inside the brush disc cover 2. The brush disc 8 is connected to the motor 7 through a transmission wheel group. The transmission wheel group in the utility model is a conventional structure of the prior art, including a driven wheel sleeved on the connecting shaft of the brush disc 8, a driving wheel sleeved on the output shaft of the motor 7, and a transmission belt connecting the driving wheel and the driven wheel.

[0026] like Figure 3 As shown, the brush plate cover 2 includes a cover body 201, and a buffer strip 202 is detachably connected to the circumference of the cover body 201 through a mounting structure 9. Specifically, the mounting structure 9 includes two embedded seats 901 arranged in a symmetrical structure on the inner edge of the cover body 201, as shown in FIG. Figure 4As shown, the outer wall of the embedded seat 901 is provided with a limiting protrusion 902. In addition, the mounting structure 9 also includes a plurality of connecting keys 903 arranged in an arc shape at equal intervals on the inner wall of the cover body 201. The connecting keys 903, the embedded seat 901 and the limiting protrusion 902 are an integrally formed structure. The present invention improves the structure of the existing brush plate cover 2. A buffer strip 202 is detachably connected to the position of the cover body 201 that is prone to collision through the mounting structure 9. The buffer strip 202 has a buffering and protective effect that effectively reduces the deformation and damage of the brush plate cover 2 caused by collision. Even if the buffer strip 202 is damaged by collision due to a small working space or a large number of obstacles, it is easy to replace. Compared with the traditional brush plate cover 2, the present invention not only has a good buffering effect on collision, but is also easy to maintain, which is beneficial to energy saving and material saving, and avoids the waste of resources caused by the overall replacement of the brush plate cover 2 due to minor damage.
