Description

Technical Field

[0001] This invention belongs to the field of cleaning robot technology, and particularly relates to a simple water cleaning robot drive motor device and a water cleaning robot. Background Technology

[0002] A pool cleaning robot (also known as an "underwater robot") is an intelligent device used to collect debris such as leaves, insects, and dust floating on the surface of a swimming pool. Its drive motors are typically mounted on both sides of the robot's main control box, providing power for movement and steering. Currently, the industry standard for securing the drive motors is to directly tighten screws from the side of the main control box, i.e., fixing the drive motors from both the left and right sides.

[0003] In the existing assembly process, operators need to flip the main control box (which typically weighs close to 3 kg) left and right to tighten the screws securing the motors from both sides. Since the motor mounting surfaces are located on opposite sides of the main control box, operators must repeatedly flip the heavy box during mass production, resulting in high labor intensity, low assembly efficiency, and severely impacting production rhythm. Furthermore, to ensure the robot's sealing performance when working underwater and prevent moisture from seeping into the screw holes, the existing technology requires glue-filling sealing at the tightened screw holes. After glue-filling, a long curing time (usually over 6 hours) is required, further slowing down the production process. Simultaneously, the glue-filling process demands high operational precision and glue quality; insufficient glue quantity, poor curing, or glue aging and detachment can lead to waterproofing failure, affecting the overall reliability of the machine. Summary of the Invention

[0004] This invention provides a simple water cleaning robot drive motor device and a water cleaning robot, aiming to solve the technical problems of existing pool cleaning robots, which require the heavy main control box to be turned upside down during motor assembly and the need to seal screw holes with sealant, resulting in difficult and complicated assembly, long time consumption, and potential reliability issues.

[0036] Main control box body;

[0037] The drive motor mechanism 200, battery 300, and main control board 400 are installed inside the main control box body;

[0038] The drive motor mechanism 200 includes a first drive motor 210, a first bracket 220, a second drive motor 230, and a second bracket 240.

The first drive motor 210 is disposed on the first bracket 220 and the first drive motor 210 extends out of the main control box body. The second drive motor 230 is disposed on the second bracket 240 and the second drive motor 230 extends out of the main control box body. The main control board 400 is disposed above the first bracket 220 and / or the second bracket 240.

[0039] In some implementations, the water cleaning robot can be a cleaning robot applied to water-related scenarios, such as a swimming pool cleaning robot, a pond cleaning robot, a river cleaning robot, or a marine floating debris cleaning robot.

[0040] The drive motor mechanism 200, battery 300, and main control board 400 are all housed within the main control box body, which provides load-bearing and support. Specifically, the first drive motor 210, first bracket 220, second drive motor 230, and second bracket 240 are all housed within the main control box body. This design ensures airtightness while eliminating the need for a potting process, effectively saving assembly time and improving overall machine reliability.

[0041] Battery 300 powers all components of the water cleaning robot. Main control board 400 functions as the main controller, controlling all components of the water cleaning robot. Drive motor mechanism 200 drives and connects to rotating wheels; specifically, the first drive motor 210 extends out of the main control box body to drive and connect to the first rotating wheel, causing the first rotating wheel to rotate. The second drive motor 230 extends out of the main control box body to drive and connect to the second rotating wheel, causing the second rotating wheel to rotate. Through the rotation of the first and second rotating wheels, the water cleaning robot can move on the water surface.

[0042] The first bracket 220 and / or the second bracket 240 are disposed above the battery 300. For example, the first bracket 220 is disposed above the battery 300; or the second bracket 240 is disposed above the battery 300; or the first bracket 220 and the second bracket 240 are disposed above the battery 300.

[0043] The first drive motor 210 is mounted on the first bracket 220, which provides support and load-bearing capacity. After the first drive motor 210 is mounted on the first bracket 220, a single unit is formed and placed inside the main control box body, for example, on the left side. The second drive motor 230 is mounted on the second bracket 240, which provides support and load-bearing capacity. After the second drive motor 230 is mounted on the second bracket 240, a single unit is formed and placed inside the main control box body, for example, on the right side. By using the first bracket 220 and the second bracket 240, the first drive motor 210 and the second drive motor 230 can be quickly assembled, saving time and effort during the assembly process and avoiding the need to repeatedly flip the main control box body.

[0044] The main control board 400 is positioned above the first bracket 220 and / or the second bracket 240. For example, the main control board 400 is positioned above the first bracket 220; or the main control board 400 is positioned above the second bracket 240; or the main control board 400 is positioned above the first bracket 220 and the second bracket 240.

[0045] In some specific embodiments of this application, reference is made to Figures 1-3 The main control box body includes a base 110 and a cover plate (not shown in the figure), and the cover plate is disposed on the base 110 to cover the base 110.

[0046] The base 110 and the cover plate are assembled. After the drive motor mechanism 200, battery 300, and main control board 400 are placed on the base 110, the cover plate is then assembled onto the base 110 to cover it. For example, the cover plate and base 110 can be assembled by drilling screws through them sequentially. Alternatively, the cover plate can be provided with a retainer and the base 110 can be provided with a slot; the retainer of the cover plate can be engaged with the slot of the base 110 to achieve assembly.

[0047] After the base 110 and cover are assembled, they provide a seal for the drive motor mechanism 200, battery 300, and main control board 400. During the operation of the water cleaning robot, water will not seep between the base 110 and the cover.

[0048] In some specific embodiments of this application, reference is made to Figure 1 and Figure 3 The base 110 is provided with a limiting groove 111, the limiting groove 111 is matched with the size of the battery 300, and the battery 300 is disposed in the limiting groove 111.

[0049] The battery 300 is square, and the limiting groove 111 is located at the bottom of the base 110. The limiting groove 111 is square, and the battery 300 can be inserted into the limiting groove 111. The limiting groove 111 can accommodate the battery 300, effectively utilizing the internal space of the main control box.

[0050] In some embodiments, the battery 300 is inserted into the limiting groove 111, and the first bracket 220 and the second bracket 240 are disposed above the battery 300.

[0051] In some specific embodiments of this application, reference is made to Figures 1-5The base 110 includes a first side 112 and a second side 113 opposite to the first side 112. The first side 112 is higher than the second side 113. The first side 112 is provided with a first fixing shaft 1121 and a third fixing shaft 1122, and the second side 113 is provided with a second fixing shaft 1131 and a fourth fixing shaft 1132. The first bracket 220 includes a first platform 221 and a second platform 222 opposite to the first platform 221. The first platform 221 is higher than the second platform 222. The first platform 221 is provided with a first fixing hole 2211, and the second platform 222 is provided with a second fixing hole 2221. The first bracket 220 is fixed to the base 110 by passing a first fixing member through the first fixing hole 2211 and the first fixing shaft 1121, and a second fixing member through the second fixing hole 2221 and the second fixing shaft 1131. The distance between the centerline of the first drive motor 210 and the first side 112 is less than the distance between the centerline of the first drive motor 210 and the second side 113. The second bracket 240 includes a third platform 241 and a fourth platform 242 opposite to the third platform 241. The third platform 241 is higher than the fourth platform 242. The third platform 241 is provided with a third fixing hole 2411, and the fourth platform 242 is provided with a fourth fixing hole 2421. The second bracket 240 is fixed on the base 110 by passing a third fixing member through the third fixing hole 2411 and the third fixing shaft 1122, and a fourth fixing member through the fourth fixing hole 2421 and the fourth fixing shaft 1132. The distance between the centerline of the second drive motor 230 and the first side 112 is less than the distance between the centerline of the second drive motor 230 and the second side 113.

[0052] In this embodiment, a first fixing shaft 1121 is provided on the first side 112, a second fixing shaft 1131 is provided on the second side 113, a first fixing hole 2211 is provided on the first platform 221, and a second fixing hole 2221 is provided on the second platform 222. The first bracket 220 is fixed on the base 110 by passing a first fixing member, such as a screw, through the first fixing hole 2211 and the first fixing shaft 1121, and by passing a second fixing member, such as a screw, through the second fixing hole 2221 and the second fixing shaft 1131. The first side 112 is higher than the second side 113. The distance between the center line of the first drive motor 210 and the first side 112 is less than the distance between the center line of the first drive motor 210 and the second side 113. This can be understood as the first bracket 220 being closer to the higher first side 112 and farther away from the lower second side 113, while the first platform 221 is higher than the second platform 222. With such a height setting, the limited space inside the main control box can be better utilized while ensuring the fixing effect of the first bracket 220 on the first drive motor 210.

[0053] In this embodiment, a third fixing shaft 1122 is provided on the first side 112, a fourth fixing shaft 1132 is provided on the second side 113, a third fixing hole 2411 is provided on the third platform 241, and a fourth fixing hole 2421 is provided on the fourth platform 242. The second bracket 240 is fixed on the base 110 by means of a third fastener, such as a screw, passing through the third fixing hole 2411 and the third fixing shaft 1122, and a fourth fastener, such as a screw, passing through the fourth fixing hole 2421 and the fourth fixing shaft 1132. The first side 112 is higher than the second side 113. The distance between the center line of the second drive motor 230 and the first side 112 is less than the distance between the center line of the second drive motor 230 and the second side 113. This can be understood as the second bracket 240 being closer to the higher first side 112 and farther away from the lower second side 113. The third platform 241 is higher than the fourth platform 242. With such a height setting, while ensuring the fixing effect of the second bracket 240 on the second drive motor 230, the limited space inside the main control box can be better utilized.
