Description

Technical Field

[0001] This invention relates to the field of motor mounting technology, specifically a novel brush motor fixing structure. Background Technology

[0002] Floor scrubbers, as a highly efficient floor cleaning device, are widely used for cleaning various hard floors in homes, supermarkets, factories, and other places. Their core working principle typically involves a motor driving a brush wheel (or roller brush) located at the front of the chassis to rotate at high speed, removing dirt from the floor. This, combined with water spraying and vacuum water extraction, achieves an integrated cleaning effect.

[0003] Currently, most floor scrubber chassis on the market are composed of separate parts. The brush cover and bearing base or battery base are usually designed as independent modules, connected by bolts, clips, and other mechanisms. This results in a large number of parts, a complex installation process, and high costs. Therefore, the applicant has developed a new type of floor scrubber chassis structure that integrates the bearing base, transition section, and brush base into a single unit. This reduces the types of materials used, simplifies installation, and significantly enhances chassis strength while reducing costs. Because the brush base and bearing base of this new floor scrubber chassis are integrated, the brush base (the structure used to install the brush motor, brush disc, etc.) cannot be independently... The height adjustment can only be performed by rotating the chassis of this new floor scrubber along the bearing base and the wheel mounting point (the bearing base and the wheel are mounted using a bearing rotation method). As a result, the brush base may be tilted during use. The current brush motor fixing structure only considers the stability and shock absorption performance of the installation, and uses a combination of general springs, washers and fasteners for installation. The angle between the brush part and the brush base cannot be adjusted. When applied to the chassis of the aforementioned new floor scrubber, there may be an angle between the brush part and the floor to be cleaned, resulting in poor floor cleaning effect. In addition, the brush part may wear unevenly in some areas, causing the brush to wear out too quickly. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a novel brush motor fixing structure. This structure solves the problem that conventional brush motor fixing structures using a combination of springs, washers, and fasteners may have issues when applied to a new type of floor scrubber chassis where the bearing base, transition section, and brush base are integrated. These issues can result in an angle between the brush portion and the floor to be cleaned, leading to poor cleaning performance. Furthermore, the brush portion may experience uneven wear, causing it to wear out too quickly.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A novel brush motor fixing structure includes: a support plate, wherein the support plate is provided with a connecting part for mounting the brush motor, and at least two mounting areas extending along the front-rear direction of the floor scrubber are provided below the support plate;

[0007] Each of the installation areas is provided with a support adjustment mechanism, which includes: a first connecting component, a second connecting component, and a stabilizer frame connected between the first connecting component and the second connecting component, located at both ends of the installation area and distributed in parallel. The bottom ends of the first connecting component and the second connecting component are threaded into the chassis of the floor scrubber, and the top ends of the first connecting component and the second connecting component are connected to the support plate. The portion of the stabilizer frame located between the first connecting component and the second connecting component is hinged to the support plate.

[0008] Preferably, the first connecting component includes: a first cap and a second cap, wherein the bottom end of the first cap is threadedly mounted on the chassis of the floor scrubber, and the bottom end of the second cap passes through an elongated hole in the support plate and is threadedly connected to the top end of the first cap.

[0009] The second connecting component includes a third cap and a fourth cap. The bottom end of the third cap is threadedly mounted on the chassis of the floor scrubber, and the bottom end of the fourth cap passes through an elongated hole in the support plate and is threadedly connected to the top end of the third cap.

[0010] The first end of the stabilizer is mounted on the first cap nail, and a spring is provided between the stabilizer and the upper part of the floor scrubber chassis;

[0011] The second end of the stabilizer is positioned between the top of the third cap nail and the bearing plate.

[0012] Preferably, elastic elements are provided on both sides of the first and second cap studs that hold the bearing plate.

[0013] Preferably, the stabilizer is an integral plate, and the plate has:

[0014] An inclined plate having a relatively high end and a low end;

[0015] The lower folding plate section, starting from the high end of the inclined plate, first bends downward to form a first vertical section, and then bends outward horizontally to form a first horizontal mounting section, with a first guide hole provided on the first horizontal mounting section;

[0016] The upper folding plate section, starting from the lower end of the inclined plate, first bends upward to form a second vertical section, and then bends outward horizontally to form a second horizontal mounting section. A second guide hole is provided on the second horizontal mounting section.

[0017] A hinge lug is fixedly connected to the top of the inclined plate.

[0018] Preferably, the first head of the first cap stud is located in the first region formed by the lower folded plate portion, and the third head of the third cap stud is located in the second region formed by the upper folded plate portion.

[0019] Preferably, the first cap stud includes: a first head and a first nail portion, the first head being fixedly connected to the top end of the first nail portion, the top end of the first head being provided with a threaded hole, and the side of the first head of the first cap stud being hexagonal.

[0020] Preferably, the second cap includes: a second head and a second nail portion, the second head being fixedly connected to the top end of the second nail portion, the second head being spherical, and the top end of the second head being provided with an internal hexagonal groove.

[0021] Preferably, the connecting portion on the carrier plate for mounting the disc brush motor includes: a through-shaft hole and a first flange hole located on the outside of the through-shaft hole in a ring-shaped distribution.

[0022] Preferably, the bearing plate is rectangular, and both the left and right sides of the bearing plate are integrally provided with clearance portions. The clearance portions include a vertical plate portion formed by bending upward from the side of the bearing plate and a flat plate portion extending from the top edge of the vertical plate portion toward the outer side of the bearing plate.

[0023] The outer side of the vertical plate and the lower part of the flat plate form an installation area.

[0024] Preferably, the flat plate portion has elongated openings corresponding to the first connecting component and the second connecting component.

[0025] This invention provides a novel brush motor fixing structure. It has the following beneficial effects:

[0026] 1. This invention, through the design of a support and adjustment mechanism, comprises a first connecting component and a second connecting component distributed along the front-rear direction of the floor scrubber. The bottom ends of both the first and second connecting components are threaded into the chassis of the floor scrubber, and the top ends of both are connected to a support plate. By adjusting the heights of the top ends of the first and second connecting components to be inconsistent, the support plate supported by the first and second connecting components is tilted. The disc brush motor mounted on the plate and the disc brush portion suspended below the disc brush motor are also tilted relative to the chassis of the floor scrubber, thus compensating for the inconsistencies in the floor scrubber's design. The chassis is tilted relative to the ground to be cleaned, ensuring that the disc brush portion suspended below the disc brush motor remains basically parallel to the ground, thus guaranteeing the cleaning effect and reducing local wear on the disc brush. In addition, a stabilizing frame is designed between the first connecting component and the second connecting component. The stabilizing frame is hinged to the support plate at the part between the first connecting component and the second connecting component. The stabilizing frame restricts the self-sliding of the support plate in the tilt direction (the support plate is subjected to the force of the disc brush motor and the brush portion), ensuring the stability of the support plate and meeting the needs of the first connecting component and the second connecting component to adjust the angle of the support plate.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Currently, the chassis of most floor scrubbers on the market are composed of separate parts. The brush cover and bearing base or battery base are usually designed as independent modules and connected by bolts, buckles and other mechanisms. There are many types of parts and the installation process is relatively complicated, resulting in higher costs. The applicant has developed a new type of floor scrubber chassis structure that integrates the bearing base, transition section and brush base into one unit. This reduces the types of materials, makes installation more convenient, and greatly enhances the strength of the chassis while reducing costs.

[0042] The new floor scrubber chassis features an integrated design of the brush base and bearing base. The brush base 1 (the structure used to install the brush motor, brush, etc.) cannot be independently adjusted in height. The chassis can only be adjusted by rotating along the bearing base and the wheel mounting point (the bearing base and the wheel are mounted using a bearing rotation method). As a result, the brush base may be tilted during use. The currently used brush motor fixing structure only considers the stability and shock absorption performance of the installation, using a combination of general springs, washers, and fasteners. The angle between the brush part and the brush base cannot be adjusted. When applied to the aforementioned new floor scrubber chassis, there may be an angle between the brush part and the floor to be cleaned, resulting in poor floor cleaning effect. Furthermore, the brush part may experience uneven wear, causing the brush to wear out too quickly.

[0043] Please refer to Figures 1-12 This invention provides a novel brush motor fixing structure, comprising: a support plate 2 and a support adjustment mechanism. The support adjustment mechanism connects the support plate 2 to the floor scrubber chassis 1. The support plate 2 has a connecting part for mounting the brush motor 4. The brush motor 4 is mounted on the support plate 2 in an inverted state. The output end of the brush motor 4 passes through the support plate 2 and the floor scrubber chassis 1 and is connected to the brush assembly. In this manner, the support plate 2 not only bears the weight of the brush motor 4 itself, but also supports the brush assembly suspended below the brush motor 4. At least two mounting areas a extending along the front-back direction of the floor scrubber are provided below the support plate 2, and a support adjustment mechanism is provided in each mounting area a.

[0044] It is understandable that a typical disc brush motor 4 includes a motor component 401 and a reducer 402. The output shaft at the bottom of the reducer 402 extends downwards, corresponding to the center hole on the floor scrubber chassis 1. The output shaft of the motor component 401 is connected to the input drive of the reducer 402. The output shaft of the motor component 401 is offset from the center hole on the floor scrubber chassis 1. At this time, the center of gravity of the disc brush motor 4 may be offset from the center of the support plate 2. One design is (shown in the attached figure): two sets of support adjustment mechanisms are designed and distributed on both sides of the support plate 2. The connecting part on the support plate 2 is offset from the center of the support plate 2. Another design is (not shown in the attached figure): the connecting part on the support plate 2 corresponds to the center of the support plate 2 and corresponds to the center hole on the floor scrubber chassis 1. At this time, the forces on both sides of the support plate 2 are inconsistent. One set of support adjustment mechanisms is designed on one side of the support plate 2 and two sets of support adjustment mechanisms are designed on the other side to ensure the stability of the support plate 2.

[0045] Specifically, installation area a extends along the front-to-back direction of the floor scrubber, forming an elongated area with two ends. The support and adjustment mechanism includes a first connecting component, a second connecting component, and a stabilizer 5 connected between the first and second connecting components, located parallel to each other at both ends of installation area a. The bottom ends of the first and second connecting components are threaded into the floor scrubber chassis 1. By rotating the first and second connecting components, the bottom ends of the first and second connecting components are threaded into the floor scrubber chassis 1, thereby adjusting the height of the top ends of the first and second connecting components. The top ends of the first and second connecting components are connected to the support plate 2. The first and second connecting components are used to support and connect the support plate 2. The tilt angle of the support plate 2 is adjusted based on the different top heights of the first and second connecting components during use. This corresponds to adjusting the angle of the disc brush motor 4 and the angle of the disc brush part to meet the actual use requirements of the disc brush part. The stabilizer 5 is located between the first and second connecting components and is hinged to the support plate 2. The stabilizer 5 is used to stabilize the support plate 2, ensure the stability of the support plate 2, and meet the requirements of the first and second connecting components to adjust the angle of the support plate 2.

[0046] Understandably, when the user adjusts the top heights of the first and second connecting components to be inconsistent, the support plate 2 supported by the first and second connecting components will be tilted. The disc brush motor 4 installed on it and the disc brush part suspended below the disc brush motor 4 will also be tilted relative to the chassis of the floor scrubber. This is to compensate for the tilt of the chassis 1 of the floor scrubber relative to the floor to be cleaned, and to ensure that the disc brush part suspended below the disc brush motor 4 is basically parallel to the floor to be cleaned.

[0047] The disc brush part includes: a second connector 11 directly connected to the output shaft of the disc brush motor 4, a disc brush 12, and a first connector 13; wherein, the second connector 11 and the first connector 13 form a detachable quick-installation structure, and the first connector 13 and the disc brush 12 are connected by a flange structure.

[0048] Specifically, the second connecting member 11 includes: a mating cylinder 1102, the inner cavity of which has a central hole that engages with the output shaft of the disc brush motor 4, and an annular sleeve 1105 is fixedly connected to the bottom of the mating cylinder 1102. The center of the annular sleeve 1105 communicates with the central opening 1106 of the mating cylinder 1102. When assembling the second connecting member 11, the output shaft of the disc brush motor 4 passes through the central hole, and a limiting nut is fixedly connected inside the annular sleeve 1105, thus enabling the mating cylinder 1102 to engage with the output shaft of the disc brush motor 4. The second connecting member 11 rotates and can be stably suspended. A limiting ring 1101 and an inner ring 1103 are fixedly connected to the outside of the mating cylinder 1102. The inner ring 1103 is located below the limiting ring 1101, and the outer diameter of the inner ring 1103 is smaller than the outer diameter of the limiting ring 1101. Several ring-shaped locking blocks 1104 are provided on the outside of the annular sleeve 1105. The outer side of the locking block 1104 extends beyond the outer diameter of the inner ring 1103. A clamping area is formed between the locking block 1104 and the annular sleeve 1105 on the outside of the inner ring 1103. The first connector 13 includes: a ring 1301, the end of which is provided with a second flange hole 1302, and the inner edge of the central hole of the ring 1301 is provided with a snap-fit ​​portion 130a corresponding to the number of snap-fit ​​blocks 1104; each snap-fit ​​portion 130a includes: a notch portion 1303, a limiting piece portion 1304, and a stop portion 1306, the end face of the limiting piece portion 1304 is fixedly provided with a wear-resistant thickened portion 1305, a gap opening 1307 is provided between one side of the limiting piece portion 1304 and the stop portion 1306, and the other side of the limiting piece portion 1304 corresponds to the notch portion 1303.

[0049] It is understood that the first connector 13 is connected to the disc brush 12 by a flange structure, and the second connector 11 is fixedly connected to the output shaft of the disc brush motor 4. When installing the disc brush 12, the notch 1303 in the first connector 13 is aligned with the locking block 1104, the first connector 13 is pushed upward and placed against the lower position of the limiting ring 1101, and then the disc brush 12 and the first connector 13 are rotated so that the limiting piece 1304 enters the clamping area formed between the locking block 1104 and the annular sleeve 1105, so as to achieve quick installation.

[0050] It is worth noting that the stop 1306 restricts the relative rotation of the second connector 11 and the first connector 13 in one direction. Reversing the rotation may cause the second connector 11 and the first connector 13 to separate. Therefore, when the disc brush motor 4 is working, it rotates in one direction. When it rotates in the opposite direction, it can automatically remove the first connector 13 and the disc brush 12.

[0051] In one embodiment, the first connecting component includes a first cap 6 and a second cap 8. The bottom end of the first cap 6 is threadedly mounted on the chassis 1 of the floor scrubber, and the bottom end of the second cap 8 passes through an elongated hole in the support plate 2 and is threadedly connected to the top end of the first cap 6.

[0052] In the structure formed by the first cap nail 6 and the second cap nail 8, the first cap nail 6 serves to support the support plate 2 and also adjusts the overall height of the first connecting assembly based on the threaded engagement between the first cap nail 6 and the floor scrubber chassis 1. The second cap nail 8 is used to clamp the support plate 2, ensuring that the support plate 2 can adjust its own height position based on the top height of the first cap nail 6.

[0053] In one embodiment, the second connecting component includes a third cap 9 and a fourth cap 10. The bottom end of the third cap 9 is threadedly mounted on the chassis 1 of the floor scrubber, and the bottom end of the fourth cap 10 passes through an elongated hole in the support plate 2 and is threadedly connected to the top end of the third cap 9.

[0054] In the structure formed by the third cap nail 9 and the fourth cap nail 10, the third cap nail 9 serves to support the support plate 2 and also adjusts the overall height of the second connecting component based on the threaded engagement between the third cap nail 9 and the floor scrubber chassis 1. The fourth cap nail 10 is used to clamp the support plate 2, ensuring that the support plate 2 can adjust its own height position based on the top height of the third cap nail 9.

[0055] The first end of the stabilizer 5 is mounted on the first cap nail 6, and the first end of the stabilizer 5 is slidably mounted on the first cap nail 6. A spring 7 is provided between the stabilizer 5 and the upper part of the floor scrubber chassis 1, and the spring 7 is used to elastically support the first end of the stabilizer 5. The second end of the stabilizer 5 is mounted between the top of the third cap nail 9 and the support plate 2, and the second end of the stabilizer 5 is slidably mounted on the fourth cap nail 10. The position of the second end of the stabilizer 5 is fixed based on the clamping between the top of the third cap nail 9 and the lower part of the support plate 2.

[0056] Understandably, the first end of the stabilizer 5 is suspended and elastically supported by the spring 7, while the second end of the stabilizer 5 is basically stabilized by the clamping of the top of the third cap 9 and the lower part of the support plate 2. In this structure, by rotating the third cap 9 to adjust the height of the second connecting component, the second end of the stabilizer 5 can be adjusted up and down accordingly without affecting the tilt of the support plate 2. By rotating the first cap 6, the first cap 6 slides relative to the stabilizer 5, and the first cap 6 pushes the support plate 2 to tilt. The support plate 2 adjusts its height up and down based on the hinged part and the first end of the stabilizer 5, without affecting the tilt of the support plate 2. Furthermore, during the above adjustment process, the stabilizer 5 can always restrict the support plate 2 from sliding along its tilt direction.

[0057] In one embodiment, elastic elements 14 are provided on both sides of the first cap stud 6 and the second cap stud 8 clamping the bearing plate 2.

[0058] It is understandable that the first cap nail 6 and the second cap nail 8 clamp the support plate 2. Considering that the support plate 2 needs to be tilted, the clamping part formed by the first cap nail 6 and the second cap nail 8 should be within the gap designed for movement of the support plate 2. The use of elastic element 14 can fill the gap area well and further improve the stability of the support plate 2.

[0059] In one embodiment, the stabilizer 5 is an integral plate, which has: an inclined plate 501, a lower folding plate portion 502, and an upper folding plate portion 503; the lower folding plate portion 502 and the upper folding plate portion 503 are located on both sides of the inclined plate 501.

[0060] The inclined plate 501 has a relatively high end and a low end; from the high end of the inclined plate 501, it is first bent downward to form a first vertical section, and then bent outward horizontally to form a first horizontal mounting section to form a lower folded plate part 502, and a first guide hole 502a is provided on the first horizontal mounting section; from the low end of the inclined plate 501, it is first bent upward to form a second vertical section, and then bent outward horizontally to form a second horizontal mounting section to form an upper folded plate part 503, and a second guide hole 503a is provided on the second horizontal mounting section.

[0061] The fourth nail portion of the fourth cap nail 10 passes through the second guide hole 503a, and the first head 601 of the first cap nail 6 passes through the first guide hole 502a, thereby basically stabilizing the position of the stabilizer 5; and, a hinge ear 506 is fixedly connected above the inclined plate 501, and the hinge ear 506 is hinged to the position below the bearing plate 2.

[0062] In one embodiment, the first head 601 of the first cap stud 6 is located in the first region 504 formed by the lower folding plate portion 502, and the third head of the third cap stud 9 is located in the second region 505 formed by the upper folding plate portion 503.

[0063] It is understandable that by designing the first region 504 and the second region 505, the stabilizer 5 can form a more compact structure with the first connecting component and the second connecting component, so that it does not occupy too much space, and in particular, it does not excessively raise the load-bearing plate 2.

[0064] In one embodiment, the first cap stud 6 includes: a first head 601 and a first nail portion 602. The first head 601 is fixedly connected to the top end of the first nail portion 602. The top end of the first head 601 is provided with a threaded hole 6a. The side of the first head 601 of the first cap stud 6 is hexagonal. The hexagonal first head 601 can facilitate the user to rotate the first cap stud 6.

[0065] In one embodiment, the second cap stud 8 includes: a second head 801 and a second stud portion 802. The second head 801 is fixedly connected to the top end of the second stud portion 802. The second head 801 is spherical and has an internal hexagonal groove at its top end.

[0066] It is understood that the first cap stud 6 and the third cap stud 9 have the same structure, and the second cap stud 8 and the fourth cap stud 10 have the same structure; based on the specific structures of the first cap stud 6 and the second cap stud 8, those skilled in the art can obtain the third cap stud 9 and the fourth cap stud 10 in the same manner.

[0067] In one embodiment, the connecting portion on the support plate 2 for mounting the disc brush motor 4 includes: a through-shaft hole 2a and a first flange hole 2b located outside the through-shaft hole 2a in a ring-shaped distribution.

[0068] The output end of the disc brush motor 4 passes through the through-shaft hole 2a on the support plate 2; based on the first flange hole 2b, the bottom of the disc brush motor 4 is installed on the support plate 2 with bolts.

[0069] In one embodiment, the support plate 2 is rectangular, and a clearance portion 3 is integrally provided on both the left and right sides of the support plate 2. The clearance portion 3 includes a vertical plate portion 301 formed by bending upward from the side of the support plate 2 and a flat plate portion 302 extending from the top edge of the vertical plate portion 301 toward the outside of the support plate 2.

[0070] The outer side of the vertical plate 301 and the lower part of the flat plate 302 form an installation area a. The design of the installation area a can further reduce the middle part of the support plate 2 (the part where the disc brush motor 4 is installed) so that it can be as close as possible to the chassis 1 of the floor scrubber.

[0071] In one embodiment, the flat plate portion 302 has an elongated opening corresponding to the first connecting component and the second connecting component.

[0072] It is understandable that the second nail portion 802 of the second cap 8 of the first connecting component passes through the elongated hole, and the fourth nail portion of the fourth cap 10 of the second connecting component also passes through the elongated hole; based on the design of the elongated hole, the bearing plate 2 can be tilted at a certain angle to meet the above-mentioned requirements for the angle adjustment of the bearing plate 2.

[0073] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
