Description

Technical Field

[0001] This utility model relates to the field of cleaning devices, and more specifically, to a base station chassis for a cleaning device and a base station having the same chassis. Background Technology

[0002] In the field of cleaning device technology, the base station, as the core component for charging, cleaning, and maintenance of the main unit (such as floor scrubbers and robotic vacuum cleaners), has a crucial impact on the operating efficiency and user experience of the main unit due to its chassis structure design. Among them, the roller brush, as a key execution component for the main unit to achieve floor cleaning, is crucial in the water-soaking process within the base station, as a fully soaked roller brush can more efficiently break down stains on the floor and reduce frictional damage during the cleaning process.

[0003] However, in existing technologies, the brush receiving area of ​​the base station chassis generally adopts a planar design. When the host injects water into the brush, due to the lack of an effective water flow constraint structure, the injected water easily spreads randomly along the plane, failing to form a concentrated water environment in the brush contact area. This directly results in a limited contact area between the brush and the water flow, making it difficult for some bristles to fully contact the water, leading to uneven wetting and localized dryness.

[0004] Therefore, a base station chassis solution is needed to solve the problem of roller brush wetting. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a base station chassis for a cleaning device and a base station having the chassis. The specific solution is as follows:

[0006] A base station chassis for a cleaning device, the cleaning device including a main unit and a base station, the base station chassis and an external base station body constituting the base station; the base station chassis is used to cooperate with a limiting member on the external base station body to fix and support the main unit, including a connecting part, a bottom plate and a side wall; The connecting part is located at one end of the base plate and is used to connect to the external base station body; the side of the base plate facing the host is a bearing surface, and the side wall and the bearing surface cooperate to form a guide channel for the host to move toward or away from the connecting part; The base plate is recessed into an arc surface on the bearing surface to form one or more roller brush grooves. The roller brush grooves are used to accommodate the roller brush on the main unit and to gather water flow when the main unit injects water into the roller brush so that the roller brush is immersed in water, thereby assisting in completing the water injection of the roller brush.

[0007] In some specific embodiments, the base station chassis further includes a drying component for drying the roller brush or the roller brush groove.

[0008] In some specific embodiments, the drying assembly includes an exhaust device, an air duct, and one or more air outlets. The air duct connects the exhaust device and the air outlets, and the air outlets are located at the roller brush to enable airflow at the roller brush groove.

[0009] In some specific embodiments, fins are provided in the air duct, and the fins are used to achieve uniform airflow inside the air duct.

[0010] In some specific embodiments, the air vents are distributed along the length of the roller brush groove.

[0011] In some specific embodiments, the sidewall is provided with guide wheels to guide the host to move in the guide channel.

[0012] In some specific embodiments, the thickness of the base plate gradually decreases from one end where the connection is located to the other end, so that the bearing surface forms a slope.

[0013] In some specific embodiments, the base station chassis further includes a fixing component for fixing the host.

[0014] In some specific embodiments, the base plate has raised anti-slip textures on the bearing surface.

A limiting member is provided on the base station body above the base station chassis, and the limiting member is used to fix the host to the base station chassis.

[0016] In some embodiments, the limiting member includes an elastic portion and a guide portion connected to each other. A guide slope is formed on one end of the guide portion facing away from the elastic portion. The guide slope gradually slopes downward in the direction toward the connecting portion. The guide portion is used to guide the host to gradually penetrate into the guide channel along the guide slope while squeezing the elastic portion. The elastic portion is used to apply elastic force to the guide portion under the squeezing of the guide portion.

[0017] Beneficial Effects: This utility model provides a base station chassis for a cleaning device and a base station incorporating it. Through the coordinated design of the arc-shaped roller brush groove and the guide channel, the roller brush is deeply self-cleaned using the roller brush groove without affecting the robot's passability, significantly improving the roller brush wetting efficiency and the stability of the host machine docking. The concave arc-shaped roller brush groove can naturally gather water flow using gravity, allowing the roller brush to be completely submerged in water, reducing water consumption while improving wetting uniformity. The guide channel formed by the side wall and the bearing surface optimizes the host machine's movement trajectory through geometric constraints, ensuring precise alignment between the roller brush and the water inlet, and preventing slippage or displacement.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] This application proposes a base station chassis for a cleaning device. Through the design of an arc-shaped roller brush groove, it solves the problems of water flow dispersion and insufficient roller brush wetting in traditional flat or shallow groove structures. Simultaneously, a guide channel ensures stable movement of the host device. A schematic diagram of the overall structure of the base station chassis for the cleaning device is attached to the specification. Figure 1 As shown, the specific solution is as follows: A base station chassis 1 for a cleaning device is provided. The cleaning device includes a main unit and a base station. The base station chassis 1 and the external base station body 2 constitute a base station. The main unit is a cleaning robot, such as a sweeping robot, primarily responsible for performing cleaning tasks, while the base station serves as the core component for charging, cleaning, and maintenance of the main unit. The base station chassis 1 of this application is the bottom structure of the base station, responsible for supporting the main unit. The other part of the base station is the base station body 2, which houses related control units, water storage units, etc. The structure of the base station chassis 1 is shown in the attached figure. Figure 1 As shown in the attached diagram, the structure of the base station is as follows. Figure 2 As shown. The base station chassis 1 is used to cooperate with the limiting components on the external base station body to fix the host. Figure 2 In this design, when the main unit of the cleaning device recharges or docks at the base station, the limiting component provides downward pressure, pressing the main unit down onto the base station chassis 1. This effectively fixes the main unit vertically. The base station chassis 1 of this application is equipped with a brush groove 4, which structurally matches the brush of the main unit. When the main unit docks accurately, its brush naturally falls into the brush groove 4. Because the shape and size of the brush groove 4 are adapted to the brush, the sidewalls of the groove physically obstruct the brush, thus limiting the main unit's horizontal movement (forward and backward, left and right). The vertical pressure of the limiting component ensures a tight fit between the main unit and the base station chassis, while the lateral restriction of the brush groove 4 prevents the main unit from shifting horizontally. The combination of these two elements forms an all-around constraint, ultimately achieving stable docking of the main unit on the base station and ensuring reliable operation of functions such as recharging and cleaning.

[0024] The base station chassis 1 includes a connecting part 13, a base plate 11, and a side wall 12. The connecting part 13 is located at one end of the base plate 11 and is used to connect to the external base station body 2. The side of the base plate 11 facing the host is the bearing surface, and the side wall 12 cooperates with the bearing surface to form a guide channel for the host to move towards or away from the connecting part 13. The connecting part 13 is actually the part that connects to the base station body 2, including mechanical and electrical connections. The side of the base plate 11 facing the host is the bearing surface, which is the core area supporting the host. The bearing surface provides a flat and stable support foundation for the host, ensuring that the center of gravity is balanced when the host is parked, reducing shaking or displacement caused by unstable placement, and laying the foundation for the precise alignment of the roller brush and the roller brush groove 4. The side wall 12 is a protrusion at the edge of the bearing surface, responsible for guiding the movement of the host. The guide channel limits the movement trajectory of the host through the physical constraints of the side wall 12, preventing the roller brush and the roller brush groove 4 from being misaligned due to directional deviation during the movement of the host, while reducing friction between the host and the inner wall of the base station and improving the smoothness of movement.

[0025] In this application, the bearing surface is not a smooth plane; it integrates many components that cooperate with the main unit, including the roller brush groove 4 and anti-slip texture. The guide channel structure formed by the side wall 12 and the bearing surface is shown in the attached figure. Figure 3 As shown.

[0026] Specifically, the base plate 11 has an arc-shaped recess on its bearing surface to form one or more roller brush grooves 4. These grooves accommodate the roller brushes on the main unit and concentrate the water flow when the main unit injects water into the roller brushes, ensuring the brushes are fully immersed and thus aiding in the water injection process. The arc-shaped geometry utilizes gravity and surface tension to constrain the water flow, solving the problems of water dispersion and loss in traditional flat or shallow groove structures. This allows the water flow to naturally converge in the contact area of ​​the roller brush, ensuring the brush (especially the bristle roots) is completely immersed in water, thus improving water injection efficiency. Furthermore, the arc-shaped surface matches the arc-shaped outer contour of the roller brush, increasing the contact area between the brush and the water, preventing localized drying of the bristles due to water dispersion, and ensuring consistent pretreatment results. Water flow concentration reduces unnecessary water waste, lowering energy consumption during the water injection process and reducing the frequency of water refills for users.

[0027] In some specific embodiments, the base station chassis 1 also includes a drying component for drying the roller brush or roller brush groove 4. After the roller brush is filled with water, moisture easily remains in the roller brush groove 4. In traditional designs, natural air drying is slow, which can easily lead to bacterial growth and odor. If water accumulates in the roller brush groove 4 for a long time, the plastic material is prone to cracking due to hydrolysis, and the metal connectors are prone to corrosion. The drying component can evaporate the moisture in the groove in a short time, extending the service life of the chassis. The drying component can quickly remove moisture, keeping the roller brush and the inside of the base station dry and improving hygiene. In addition, the drying component can also dry the roller brush, and the dried roller brush can be directly used for the next cleaning operation, avoiding a decrease in cleaning effect due to moisture. The drying component can accelerate moisture evaporation through heating, airflow, or other methods.

[0028] In some specific embodiments, the drying assembly includes an exhaust device 14, an air duct 15, and one or more air outlets 16. The air duct 15 connects the exhaust device 14 and the air outlets 16. The air outlets 16 are located at the roller brush and are used to achieve airflow at the roller brush groove 4. The specific structure is shown in the attached figure. Figure 4 As shown. The exhaust device 14 is the core component providing airflow power, such as a fan, responsible for generating directional airflow. The air duct 15 connects the exhaust device 14 and the air outlet 16, used to constrain and guide the airflow direction, ensuring that the airflow is accurately delivered to the target area. The air outlet 16, as the airflow output end, is directly set at the corresponding position of the roller brush, such as the side or bottom of the roller brush groove 4, to accelerate the evaporation of moisture on the surface of the roller brush and inside the roller brush groove 4 by spraying airflow. Through the path design of "exhaust device 14 → air duct 15 → air outlet 16", the airflow is concentrated on the roller brush and roller brush groove 4, avoiding the problems of airflow dispersion and high energy consumption in traditional drying methods (such as overall blowing), and improving drying efficiency. The design of the air duct 15 can be adapted to the internal space of the base station chassis 1, guiding the airflow to the roller brush groove 4 area without increasing the size of the base station. By adjusting the power of the exhaust device 14, the wind speed and air volume can be flexibly controlled to adapt to different humidity scenarios.

[0029] In some specific embodiments, fins are provided in the air duct 15 to achieve uniform airflow within the air duct 15. The fins are airflow guiding structures inside the air duct 15, typically thin sheets, spaced apart or spirally arranged along the length of the air duct 15. Their function is to guide airflow evenly along the cross-section of the air duct 15, preventing localized airflow speeds from being too fast or too slow. Due to the size limitations of the base station, the air duct 15 extends in a tortuous manner within the base station, causing airflow turbulence. The fins can regulate the airflow, ensuring that the airflow volume and velocity at each air outlet 16 remain consistent. Uniform airflow ensures that all parts of the roller brush are dried simultaneously, preventing bacterial growth or roller brush deformation caused by localized dampness. Furthermore, with uniform airflow, there is no need to increase fan power to compensate for insufficient localized airflow, which also reduces base station noise.

[0030] In some specific embodiments, the air vents 16 are distributed along the length of the roller brush groove 4. The roller brush is a long, rotating component, and its moisture distribution extends continuously along its length. If the air vents 16 are concentrated in a certain area, even with uniform airflow, dead zones with insufficient drying at both ends will appear. Air vents 16 distributed along the length can perfectly adapt to the shape of the roller brush. The length of the roller brush groove 4 matches the length of the main roller brush, and the air vents 16 are arranged linearly along this length, with uniform spacing between adjacent air vents 16. For a dual-roller brush design, two sets of parallel air vent arrays 16 are correspondingly provided.

[0031] In some embodiments, the air vents 16 exist in an array, with multiple sub-air vents 16 evenly distributed along the length of the roller brush groove 4, so that the airflow covers more than 95% of the roller brush surface. (See attached...) Figure 4 In the middle, the air vents 16 are distributed in a strip structure. The air vents 16 are directly opened on the side wall 12 or bottom of the roller brush groove 4, without the need for additional airflow distribution components. Compared with the combination of centralized air vents 16 and complex flow distribution structure, the chassis weight can be reduced and the material cost can be reduced.

[0032] In some specific embodiments, guide wheels 17 are provided on the side wall 12 to guide the host to move in the guide channel. The core function of the guide wheels 17 on the side wall 12 is to guide the host to move along a preset path and limit lateral deviation. The guide wheels 17 include cylindrical rollers, which can be made of wear-resistant rubber or nylon and have anti-slip textures on the surface. The guide channel forms a physical constraint with the side wall 12 through the bearing surface, but the host may experience lateral displacement due to inertia or uneven ground during movement. The guide wheels 17 use rolling friction instead of sliding friction to convert lateral displacement into the rotational motion of the rollers. At the same time, through mechanical cooperation with the host, they achieve precise guidance, ensuring that the host enters the base station in a straight line and avoids collisions with the side wall 12 or the roller groove 4.

[0033] In some specific embodiments, the thickness of the base plate 11 gradually decreases from one end where the connecting part 13 is located to the other end, forming a slope on the bearing surface. The thickness of the base plate 11 decreases from the connecting part 13 to the other end, forming an inclined slope of 5°-15°, the core function of which is to assist in water flow collection and guide the movement of the main unit. The inclination angle of the slope needs to be designed comprehensively based on the depth of the roller brush groove 4, the water flow velocity, and the weight of the main unit.

[0034] The slope structure of the base plate 11 is shown in the attached diagram. The main unit must move along the "low→high" slope trajectory to accurately reach the corresponding stopping position of the connecting part 13, avoiding docking failure due to horizontal deviation. After docking, the main unit stops at the end of the connecting part 13, and the reverse slope of the slope can form "anti-backward resistance". If the main unit has a slight tendency to move due to vibration or external force, it needs to overcome the height difference of the slope to reduce unexpected displacement. With the fixing components, the vibration resistance of the main unit after docking can be increased by 40%, which is especially suitable for the stability requirements of high-speed rotating cleaning of the roller brush.

[0035] In some specific embodiments, the base station chassis 1 also includes a fixing component for securing the main unit. The fixing component can be mechanically connected to secure the main unit within the base station, preventing it from shaking during charging, cleaning, or movement. Typical structures include: a spring-loaded latch: after the main unit is in place, the latch automatically engages with the bottom groove; a release button must be pressed to unlock it. A magnetic attraction device: a permanent magnet is embedded in the base station chassis 1, and a ferromagnetic sheet is installed at the corresponding position on the bottom of the main unit. Elastic clamping arms: elastic arms on both sides clamp the sides of the main unit through deformation, accommodating main unit models of different widths. Preferably, the fixing component consists of multiple pressure plates mounted on the base station that secure the main unit from top to bottom, thereby achieving vertical fixation of the main unit.

[0036] In some specific embodiments, the base plate 11 has raised stripes on its bearing surface to increase the friction of the host in the guide channel. Exemplarily, the raised stripes on the bearing surface are continuous or discontinuous structures with a height of 0.5-2 mm, and their shapes include sawtooth, diamond, or dot arrays, made of the same material as the base plate 11 (such as ABS plastic). The stripes are arranged parallel to each other along the direction of host movement (i.e., the length direction of the guide channel), with a spacing of 2-5 mm. The stripes can be integrally injection molded, with a frosted surface treatment to further enhance friction while preventing sharp edges from scratching the rubber wheels or sensors at the bottom of the host.

[0037] A base station for a cleaning device includes a base station body 2 and a base station chassis 1 as described above. The structure of the base station is shown in the attached figure. Figure 2 As shown. A limiting member 3 is provided on the base station body 2 above the base station chassis 1. The limiting member 3 is used to fix the host to the base station chassis 1.

[0038] In some embodiments, the limiting member 3 includes an elastic portion 31 and a guide portion 32 connected to each other. A guide slope is formed on one end of the guide portion 32 facing away from the elastic portion 31. The guide slope gradually slopes downwards towards the connecting portion 13. The guide portion 32 guides the main unit to gradually penetrate deeper into the guide channel along the guide slope while simultaneously compressing the elastic portion 31. The elastic portion 31 applies elastic force to the guide portion 32 under the compression of the guide portion 32. The structure of the limiting member 3 is shown in the attached figure. Figure 6 As shown.

[0039] The elastic part 31 is typically a structure with elastic deformation capability, with one end fixed to the base station body and the other end connected to the guide part 32. The end of the guide part 32 facing away from the elastic part 31 is machined with a guide slope. A key feature of this slope is that it gradually slopes downwards towards the connecting part 13. From the position where the host just contacts the limiting member 3 to the position where the host finally stops, the slope has a downward trend. When the host moves towards the base station, it first contacts the guide slope of the guide part 32. As the host slides along the slope, its outer shell continuously applies a lateral / diagonal pressure to the guide part 32. Since the guide part 32 is connected to the elastic part 31, this pressure is transmitted to the elastic part 31, forcing it to deform. The guide part 32 converts this elastic force into a contact force on the host. The deeper the host slides along the slope, the greater the deformation of the elastic part 31, and the stronger the contact force of the guide part 32 on the host, ensuring that the host always fits tightly against the slope. In practical applications, the base station can be equipped with multiple limiting members 3. (The text ends abruptly here.) Figure 6 In the middle, the elastic part 31 includes a spring and a guide post. The guide ramp is shown in the attached figure. Figure 6 The region N in the diagram is shown.

[0040] This invention provides a base station chassis for a cleaning device and a base station incorporating it. Through the coordinated design of the arc-shaped roller brush groove and the guide channel, the efficiency of the roller brush immersion and the stability of the host unit docking are significantly improved. The recessed arc-shaped roller brush groove utilizes gravity to naturally collect water flow, ensuring the roller brush is completely submerged in water, reducing water consumption while improving immersion uniformity. The guide channel formed by the sidewall and the bearing surface optimizes the host unit's movement trajectory through geometric constraints, ensuring precise alignment between the roller brush and the water inlet, preventing slippage or misalignment.
