However, with the continuous advancement of technology and the diversification of user needs, the existing floor scrubber frames are generally front-wheel drive designs. However, with changes in market demand, manufacturers may encounter situations where the floor scrubber drive is changed from front-wheel drive to rear-wheel drive during the production process. However, the existing front-wheel drive frame structure does not take into account this kind of later modification, which requires manufacturers to re-weld the front-wheel drive frame to convert it into a rear-wheel drive frame. This frame welding operation wastes time and affects the normal production and assembly of the floor scrubber. In view of the above problems, there is an urgent need for a floor scrubber frame design that can be adapted to both front-wheel drive and rear-wheel drive. Therefore, this utility model proposes a new type of floor scrubber frame design. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides, for example Figure 1-4 As shown:

[0033] Example 1,

[0034] A floor scrubber chassis that is compatible with both front-wheel drive and rear-wheel drive includes: a front-wheel drive chassis body 1, an axle support assembly and a motor mounting structure;

[0035] It should be noted that the axle support assembly is used for supporting and placing the axle, and the motor mounting structure is set on the side of the inner liner 2. The motor mounting structure is used for mounting the rear drive motor.

[0036] Specifically, the axle support assembly includes an inner liner plate 2 welded to the top of the front-drive frame body 1, and an outer liner plate 3 welded to the side of the inner liner plate 2. The inner liner plate 2 and the outer liner plate 3 are used for the placement of the rear axle.

[0037] It should be noted that the motor mounting structure includes a movable block 4, the end of which is inserted into the side of the inner liner plate 2. The inserted end of the inner liner plate 2 is provided with a connecting part for motor mount installation. An adjustment part 6 for adjusting the position of the movable block 4 is provided on the outside of the movable block 4.

[0038] Specifically, the inner lining plate 2 has through holes on its side for the movable block 4 to pass through, and the connecting part includes: a support hole 401 and a mounting hole 402;

[0039] It should be noted that multiple support holes 401 are symmetrically opened at the end of the movable block 4, and multiple mounting holes 402 are symmetrically opened at the end of the movable block 4. The mounting holes 402 are used to thread the motor base. The mounting holes 402 are threaded holes, and the central axis of the mounting holes 402 coincides with the central axis of the support holes 401.

[0040] Specifically, the adjusting part 6 includes: a sleeve 602, an adjusting bolt 601, an anti-loosening component, and a limiting component;

[0041] It should be noted that the end of the sleeve 602 is inserted into the side of the movable block 4, the adjusting bolt 601 is threaded into the middle of the sleeve 602, the anti-loosening component is set in the inner cavity of the sleeve 602, and the limiting component is set in the side of the movable block 4.

[0042] Specifically, the adjusting bolt 601 is used to press the side of the movable block 4, the anti-loosening component is used to prevent the adjusting bolt 601 from loosening, the limiting component is used to prevent the movable block 4 from moving, the sleeve 602 and the movable block 4 are fixed by welding at the insertion point, and an isolation block 605 is welded to the end of the adjusting bolt 601. The isolation block 605 is used to prevent the thread at the end of the adjusting bolt 601 from wearing.

[0043] Example 2,

[0044] A limiting component and an anti-loosening component are applied to the floor scrubber frame adapted for front-drive and rear-drive vehicles in Embodiment 1;

[0045] Specifically, the limiting components include: the limiting plate 5 and the positioning bolt 501;

[0046] It should be noted that the limiting plate 5 is located on the side of the movable block 4 and on the side of the inner liner plate 2 away from the anti-loosening component. The ends of multiple positioning bolts 501 are sequentially inserted and connected to the side of the limiting plate 5 and the movable block 4. Multiple sets of positioning holes 403 are opened on the side of the movable block 4. The positioning holes 403 are used for the insertion of the positioning bolts 501.

[0047] Specifically, the positioning hole 403 is a threaded hole, and the limiting plate 5 is fixed by the positioning bolt 501, so that the movable block 4 cannot be disengaged from the insertion point of the inner lining plate 2.

[0049] Specifically, the pressure ring 603 is sleeved on the outside of the adjusting bolt 601, and the compression spring 604 is sleeved on the outside of the adjusting bolt 601 and located on the side of the pressure ring 603 close to the inner liner plate 2.

[0050] It should be noted that the inner wall of the sleeve 602 is provided with threads corresponding to the adjusting bolt 601. The pressure ring 603 is fixed to the outer side of the adjusting bolt 601 by welding. The compression spring 604, which is squeezed, pushes the pressure ring 603, so that the thread engagement between the adjusting bolt 601 and the sleeve 602 is in tight contact, thus preventing the adjusting bolt 601 from becoming loose.

[0051] In practical use, a motor mounting structure is provided on the side of the inner liner plate 2 of the front-drive frame body 1. The side of the movable block 4 in the motor mounting structure is provided with a connecting part for installing the rear-drive motor. The position of the movable block 4 is adjusted by adjusting part 6. The movable block 4 is driven to move by rotating adjusting bolt 601. Then, the limiting plate 5 is fixed. The position of the movable block 4 is limited by the combination of limiting plate 5 and adjusting bolt 601. This allows the position of the connecting part to be adjusted according to the model of the motor. Compared with the existing front-drive frame, this design adds a connecting part for installing the rear-drive motor, avoiding the problem that the rear-drive motor cannot be installed on the front-drive bracket later.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
