Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a cleaning device. Background Technology

[0002] A cleaning device is a device that automatically cleans a surface as it moves across it. For example, the surface to be cleaned can be a floor, and the cleaning device can include a robotic vacuum cleaner.

[0003] Cleaning equipment typically consists of a main body, wheels, and a cleaning module. The wheels and cleaning module are both located on the side of the main body facing the surface to be cleaned. As the wheels rotate, they propel the main body across the surface. During this movement, the cleaning components within the cleaning module rotate to clean the surface. The cleaning equipment also includes a battery, housed within the main body, which provides power for its movement.

[0004] However, existing cleaning equipment has the following problems: the layout inside the body affects the layout space of other modules inside the body, resulting in low space utilization. In addition, the battery is located inside the existing body, and when testers test the cleaning equipment that is not fully assembled, the battery is easy to fall off from the side of the body facing the surface to be cleaned. Utility Model Content

[0005] This application provides a cleaning setup that can solve at least one of the problems in existing cleaning equipment.

[0006] In a first aspect, embodiments of this application provide a cleaning device, including:

[0007] The fuselage contains a battery mounting structure.

[0008] The first functional module and the second functional module are both located on the side of the machine body facing the surface to be cleaned, and along the forward direction of the cleaning equipment, the first functional module and the second functional module are located on opposite sides of the battery fixing structure.

[0009] The battery is located within the battery fixing structure; in the height direction of the body: the projection of the battery overlaps with the projection of at least one of the first functional module and the second functional module.

[0010] The cleaning device provided in this application adopts a layout in which a first functional module and a second functional module are respectively arranged on opposite sides of the battery fixing structure along the forward direction of the cleaning device. The projection of the battery in the height direction of the device overlaps with the projection of at least one of the first and second functional modules, forming a layered layout in three-dimensional space. This achieves a three-dimensional arrangement of the battery and at least one of the first and second functional modules in the height direction of the device. This effectively utilizes the spatial dimension of the device in the height direction, allowing the battery and at least one of the first and second functional modules to complement each other in space. This ensures that the device can provide independent installation space for the first functional module, the second functional module, and the battery, while improving the utilization rate of the internal space, facilitating the miniaturization design of the cleaning device. Alternatively, with improved space utilization, more functions can be designed for the cleaning device without affecting its size, meeting users' needs for more functions.

[0011] In some embodiments, in the height direction of the housing, the projections of the first functional module and the second functional module both coincide with at least a portion of the projection of the battery. This achieves a three-dimensional stacked layout of the battery, the first functional module, and the second functional module in the height direction of the housing, further improving the utilization rate of the internal space of the housing. Furthermore, this allows for the installation of larger capacity batteries or more complex first and second functional modules while maintaining the same overall dimensions of the cleaning equipment.

[0012] In some embodiments, the side of the body facing the surface to be cleaned has a first mounting structure and a second mounting structure. A first functional module is disposed within the first mounting structure and matches the shape of the first mounting structure; a second functional module is disposed within the second mounting structure and matches the shape of the second mounting structure.

[0013] Along the forward direction of the cleaning equipment, the first mounting structure and the second mounting structure are located on opposite sides of the battery fixing structure;

[0014] In the height direction of the fuselage: the projections of the first mounting structure and the second mounting structure both coincide with at least a portion of the battery's projection. This allows the first functional module and the second functional module to be mounted on the fuselage via the first mounting structure and the second mounting structure, respectively. Furthermore, based on the fact that the battery simultaneously and at least partially coincides with the projections of the first functional module and the second functional module in the height direction of the fuselage, by ensuring that the projections of both the first and second mounting structures coincide with at least a portion of the battery's projection, and by matching the shape of the first functional module with the first mounting structure and the shape of the second functional module with the second mounting structure, it is ensured that when the first and second functional modules are mounted on the fuselage, the projections of both the first and second functional modules coincide with at least a portion of the battery's projection in the height direction of the fuselage.

[0015] In some embodiments, in the height direction of the body, the end of the battery fixing structure adjacent to the surface to be cleaned is the support end, and the end of the battery fixing structure away from the surface to be cleaned is the inlet end, and the inlet end has an opening for the battery to enter and exit.

[0016] Along the forward direction of the cleaning equipment, the size of the inlet end is larger than the size of at least part of the support end;

[0017] At least a portion of the inlet end is located on the side of the first and second mounting structures opposite to the surface to be cleaned, and in the height direction of the machine body: the projections of the first and second mounting structures both coincide with at least a portion of the projection of the inlet end. By setting the size of the inlet end to be larger than the size of at least a portion of the support end, the battery fixing structure has a structure that is wider at the top and narrower at the bottom along the height direction of the machine body, so that the battery can enter the battery fixing structure through the opening and be fixed in the battery fixing structure by the support end.

[0018] Furthermore, by limiting the position of the inlet end relative to the first mounting structure and the second mounting structure, it can be ensured that in the height direction of the body, the projections of the first mounting structure and the second mounting structure coincide with a portion of the projection of the battery fixing structure. This facilitates that when the battery is fixed in the battery fixing structure, in the height direction of the body, the projections of the first mounting structure and the second mounting structure coincide with at least a portion of the projection of the battery.

[0019] In some embodiments, the side of the machine body facing the surface to be cleaned is provided with a first receiving cavity and a second receiving cavity;

[0020] The first receiving cavity corresponds to the first functional module and forms a first mounting structure, so that when the first functional module is disposed in the first receiving cavity, the first functional module can be mounted on the machine body; the second receiving cavity corresponds to the second functional module and forms a second mounting structure, so that when the second functional module is disposed in the second receiving cavity, the second functional module can be mounted on the machine body.

[0021] In some embodiments, the battery fixing structure has a receiving cavity with an opening located on the side of the receiving cavity away from the surface to be cleaned, and the cavity wall has a supporting surface.

[0022] When the battery is placed in the receiving cavity through the opening, the supporting surface supports the bottom of the battery, with the bottom of the battery facing away from the opening. This arrangement facilitates battery installation through the opening of the receiving cavity and supports the bottom of the battery through the supporting surface. This also prevents the battery from detaching and being damaged when testers perform tests on the incomplete cleaning equipment, as the side facing the surface to be cleaned may be damaged.

[0023] In some embodiments, the battery includes a first battery or a second battery, and the first battery and the second battery have different shapes;

[0024] The battery fixing structure has a receiving cavity, and the cavity wall has multiple supporting surfaces, including a first supporting surface and a second supporting surface.

[0025] When the first battery is placed in the accommodating cavity, the first supporting surface supports the first battery; when the second battery is placed in the accommodating cavity, the second supporting surface supports the second battery.

[0026] The first support surface ensures stable support for the first battery within the battery fixing structure, preventing shaking or displacement. Similarly, the second support surface ensures stable support for the second battery within the same structure, preventing shaking or displacement. Because the first and second batteries have different shapes, an adaptive structure can be formed within the accommodating cavity, allowing the battery fixing structure to accommodate batteries of different shapes and reducing the production cost of the cleaning equipment.

[0027] In some embodiments, the receiving cavity has an opening located on the side of the receiving cavity opposite to the surface to be cleaned, and the opening is used to allow a first battery or a second battery to pass through.

[0028] When the first battery is placed in the receiving cavity, the first support surface supports the bottom of the first battery, and the bottom of the first battery is set away from the opening to prevent the first battery from coming out of the receiving cavity from the side of the machine body facing the surface to be cleaned and being damaged.

[0029] When the second battery is placed in the receiving cavity, the second support surface supports the bottom of the second battery, and the bottom of the second battery is positioned away from the opening to prevent the second battery from coming out of the receiving cavity from the side of the machine body facing the surface to be cleaned and being damaged.

[0030] In some embodiments, when the first battery is disposed in the receiving cavity, the other cavity walls of the receiving cavity do not contact the first battery;

[0031] When the second battery is placed inside the receiving cavity, the other walls of the receiving cavity do not contact the second battery. This arrangement ensures that the first support surface corresponds to the first battery, and the second support surface corresponds to the second battery, allowing the battery fixing structure to precisely fit and secure batteries of different shapes placed inside.

[0032] In some embodiments, both the first battery and the second battery extend along the width direction of the body, which is perpendicular to the forward direction of the cleaning device.

[0033] The first support surface supports the bottom side of the first battery in the extending direction;

[0034] The second support surface supports the bottom of the second battery on its side in the extending direction.

[0035] Since the first and second batteries typically have large side areas along their extension direction, the arrangement of supporting the bottom side of the first battery along its extension direction with a first support surface and supporting the bottom side of the second battery along its extension direction with a second support surface enhances the securing effect of the battery fixing structure on the first and second batteries. Furthermore, this arrangement can also counteract the inertial forces generated during acceleration or deceleration of the cleaning equipment, thereby improving the reliability of the fixing of the first and second batteries.

[0036] In some embodiments, the shape of the first support surface matches the shape of the side surface of the supported first battery. This configuration ensures a high degree of matching between the shapes of the first battery and the first support surface, maximizing the contact area between them and guaranteeing support stability. Furthermore, the matching shape of the first support surface with the first battery ensures uniform stress distribution at the contact points, preventing localized stress concentration and extending the battery's lifespan.

[0037] In some embodiments, the shape of the second support surface matches the shape of the side surface of the supported second battery. This configuration ensures a high degree of matching between the shapes of the second battery and the second support surface, maximizing the contact area and guaranteeing support stability. Furthermore, the matching shape of the second support surface with the shape of the second battery ensures uniform stress distribution at the contact points, preventing localized stress concentration and extending the battery's lifespan.

[0038] In some embodiments, in a cross-sectional direction parallel to the height direction of the fuselage, the cross-sectional shape of the first battery is a first shape, and the cross-sectional shape of the second battery is a second shape.

[0039] The first shape matches a triangle, and the second shape matches a polygon with more than three sides. This arrangement allows the first support surface to support the first battery that matches the triangle, and the second support surface to support the second battery that matches the polygon with more than three sides. This makes the battery mounting structure adaptable to the installation of batteries of different shapes, thereby reducing the production cost of the cleaning equipment.

[0040] In some embodiments, when the first battery or the second battery is disposed within the receiving cavity, one of the apex corners of the first shape and the second shape faces away from the opening, and the apex corner forms the bottom of the first battery or the bottom of the second battery. Since the apex corners of the triangle and the polygon both exhibit a "V" shape, making the apex corner facing away from the opening form the bottom of the first battery or the bottom of the second battery ensures that when the first battery or the second battery is disposed within the receiving cavity, the bottom of both the first battery and the bottom of the second battery exhibit an inverted "V" shape. This prevents the first battery or the second battery from easily detaching from the side of the body facing the surface to be cleaned due to its shape constraints. Furthermore, this also reduces the size of the battery fixing structure at the bottom of the corresponding battery, facilitating an overlap between the projection of the battery and the projection of at least one of the first and second functional modules in the height direction of the body, thereby improving the utilization rate of the internal space of the body.

[0041] In some embodiments, in the height direction of the fuselage:

[0042] The accommodating cavity includes a first cavity segment and a second cavity segment that are interconnected. Compared to the second cavity segment, the first cavity segment is located closer to the surface to be cleaned. Along the direction from the second cavity segment to the first cavity segment, the size of the first cavity segment in the forward direction of the cleaning device decreases. This is so that the size of the first cavity segment in the forward direction of the cleaning device gradually decreases along the direction from the second cavity segment to the first cavity segment. This allows the first cavity segment to accommodate the inverted "V" shaped structure of the first and second batteries at the bottom, while also reducing the size of the battery fixing structure at the bottom of the corresponding battery. This allows the first and second functional modules to be located close to the bottom of the battery, improving the utilization rate of the internal space of the device.

[0043] A portion of the cavity wall of the first cavity section forms a second support surface, so that when the second battery is placed in the accommodating cavity, a portion of the cavity wall of the first cavity section can support the second battery and fix the second battery in the battery fixing structure.

[0044] In some embodiments, a portion of the cavity wall of the first cavity segment forms a first support surface, which is located on the side of the second support surface facing the surface to be cleaned. When the first battery is disposed within the receiving cavity, there is a gap between the first battery and the second support surface. This configuration ensures that when the first battery is disposed within the receiving cavity, a portion of the cavity wall of the first cavity segment can support the first battery, securing it within the battery fixing structure while preventing contact between the first battery and the second support surface, thus enabling proper installation of the first battery.

[0045] In some embodiments, the first cavity segment is provided with two second support surfaces, which are distributed on both sides of the second battery, so that the second support surfaces provide symmetrical support for the second battery and ensure the stability of the second battery.

[0046] The first support surface connects to two second support surfaces to support the first battery while avoiding the two second support surfaces, and to form a continuous support structure to ensure the fixation effect of the first battery within the battery fixing structure.

[0047] In some embodiments, the portion containing the first cavity segment forms a support end of the battery fixing structure to support the battery and ensure the stability of the battery fixing.

[0048] The opening is located on the side of the second cavity section opposite to the first cavity section, and the part where the second cavity section is located forms the open end of the battery fixing structure to facilitate battery installation.

[0049] In some embodiments, a battery end cap is also included. The battery fixing structure has a receiving cavity with an opening for the battery to pass through. The battery end cap covers the opening and is connected to the body to shield the opening, preventing external dust or other impurities from entering the receiving cavity through the opening, causing battery contamination and affecting battery life, and preventing the battery from falling out of the opening and causing damage.

[0050] In some embodiments, the battery mounting structure has heat dissipation holes that are connected to the interior of the battery mounting structure. This allows the heat generated by the battery during operation to be dissipated through the heat dissipation holes, thereby preventing heat accumulation that could cause the battery temperature to become too high and affect the normal use of the battery.

[0051] In some embodiments, a buffer is also included, which is disposed within the battery fixing structure and sandwiched between the battery fixing structure and the battery. This allows the buffer to absorb vibrations generated during the operation of the cleaning equipment, thereby protecting the battery from damage.

[0052] In some embodiments, the first functional module includes a driven wheel assembly, and the second functional module includes a cleaning module. This configuration allows for efficient use of the internal space of the device, enabling the driven wheel assembly, cleaning module, and battery to be installed on the device. Furthermore, it allows the cleaning device to perform both cleaning and movement functions while improving space utilization, thus facilitating miniaturization of the cleaning equipment.

[0053] In some embodiments, the cleaning equipment further includes a mopping module, which includes a roller-type mop or a conveyor-type mop.

[0054] The mopping module is located on the side of the machine body facing the surface to be cleaned, and it is situated on the side of the cleaning module away from the battery; that is, the mopping module and the battery are located on opposite sides of the cleaning module. This arrangement further optimizes the space utilization of the machine body. Thus, without affecting the size of the cleaning device, it enables the cleaning device to perform not only sweeping but also mopping functions.

[0055] Secondly, this application provides a cleaning device with a body, a battery fixing structure inside the body, a receiving cavity inside the battery fixing structure, an opening in the receiving cavity located on the side of the receiving cavity away from the surface to be cleaned, a bottom wall of the receiving cavity located on the side of the receiving cavity close to the surface to be cleaned, and a supporting surface on the cavity wall.

[0056] When the battery is placed inside the accommodating cavity, the supporting surface supports the bottom of the battery, and the bottom of the battery is positioned away from the opening.

[0057] The cleaning device provided in this application embodiment has a battery installed in the housing cavity of the battery fixing structure through an opening to facilitate battery installation. The support surface is used to support the battery away from the bottom of the opening. In this way, when the tester tests the cleaning device that is not fully assembled, the battery can be prevented from falling out of the housing cavity towards the surface to be cleaned and causing damage.

[0058] In some embodiments, the battery includes a first battery or a second battery, and the first battery and the second battery have different shapes;

[0059] The cavity wall of the receiving cavity has multiple support surfaces, including a first support surface and a second support surface;

[0060] When the first battery is placed inside the receiving cavity, the first supporting surface supports the bottom of the first battery; when the second battery is placed inside the receiving cavity, the second supporting surface supports the bottom of the second battery. The first supporting surface ensures stable support for the first battery within the receiving cavity, preventing shaking or displacement. Furthermore, it prevents the first battery from detaching from the receiving cavity towards the surface to be cleaned and causing damage when the cleaning device is not fully assembled. Similarly, the second supporting surface ensures stable support for the second battery within the receiving cavity, preventing shaking or displacement. It also prevents the second battery from detaching from the receiving cavity towards the surface to be cleaned and causing damage when the cleaning device is not fully assembled.

[0061] Furthermore, since the first and second batteries have different shapes, an adaptive structure can be formed within the accommodating cavity, allowing the battery fixing structure to be compatible with batteries of different shapes, thereby reducing the production cost of the cleaning equipment.

[0062] In some embodiments, when the first battery is disposed in the receiving cavity, the other cavity walls of the receiving cavity do not contact the first battery;

[0063] When the second battery is placed inside the receiving cavity, the other walls of the receiving cavity do not contact the second battery. With this configuration, the first and second support surfaces correspond to the first and second batteries respectively, so that the battery fixing structure can precisely fit and fix batteries of different shapes placed inside.

[0064] In some embodiments, both the first battery and the second battery extend along the width direction of the body, which is perpendicular to the forward direction of the cleaning device.

[0065] The first support surface supports the bottom side of the first battery in the extending direction;

[0066] The second support surface supports the bottom of the second battery on its side in the extending direction.

[0067] Since the first and second batteries typically have a large surface area on their sides along the width of the device, the arrangement of supporting the bottom side of the first battery in the extending direction with a first support surface and supporting the bottom side of the second battery in the extending direction with a second support surface enhances the securing effect of the battery fixing structure on the first and second batteries. Furthermore, this arrangement can also counteract the inertial forces generated during acceleration or deceleration of the cleaning equipment, thereby improving the reliability of the securing of the first and second batteries.

[0068] In some embodiments, in a cross-sectional direction parallel to the height direction of the fuselage, the cross-sectional shape of the first battery is a first shape, and the cross-sectional shape of the second battery is a second shape.

[0069] The first shape matches a triangle, and the second shape matches a polygon with more than three sides. This arrangement allows the first support surface to support the first battery that matches the triangle, and the second support surface to support the second battery that matches the polygon with more than three sides. This makes the battery mounting structure adaptable to the installation of batteries of different shapes, thereby reducing the production cost of the cleaning equipment.

[0070] In some embodiments, when the first battery is disposed within the receiving cavity, one of the apex corners of both the first and second shapes faces away from the opening, and the apex corner forms the bottom of the first battery or the bottom of the second battery. Since the apex corners of both triangles and polygons exhibit a "V" shape, making the apex corner facing away from the opening form the bottom of the first battery or the bottom of the second battery ensures that when the first or second battery is disposed within the receiving cavity, the bottom of both the first and second batteries exhibits an inverted "V" shape. This prevents the first or second battery from easily detaching from the side of the body facing the surface to be cleaned due to its shape constraints. Furthermore, this reduces the size of the battery fixing structure at the bottom of the corresponding battery, allowing the projection of the battery to overlap with the projection of at least one of the first and second functional modules in the height direction of the body, thus improving the space utilization of the body.

[0071] In some embodiments, in the height direction of the housing, the accommodating cavity includes a first cavity segment and a second cavity segment that are interconnected. Compared to the second cavity segment, the first cavity segment is disposed closer to the surface to be cleaned, and the size of the first cavity segment in the forward direction of the cleaning device decreases along the direction from the second cavity segment to the first cavity segment. This is so that the size of the first cavity segment in the forward direction of the cleaning device gradually decreases along the direction from the second cavity segment to the first cavity segment. This allows the first cavity segment to adapt to the inverted "V" shaped structure of the first and second batteries at the bottom, while reducing the size of the battery fixing structure at the bottom of the corresponding battery. This allows the first functional module and the second functional module to be disposed close to the bottom of the battery, improving the space utilization of the housing.

[0072] A portion of the cavity wall of the first cavity section forms a second support surface, so that when the second battery is placed in the accommodating cavity, a portion of the cavity wall of the first cavity section can support the second battery and fix the second battery in the battery fixing structure.

[0073] In some embodiments, a portion of the cavity wall of the first cavity segment forms a first support surface, which is located on the side of the second support surface facing the surface to be cleaned. When the first battery is disposed within the receiving cavity, there is a gap between the first battery and the second support surface. This configuration ensures that when the first battery is disposed within the receiving cavity, a portion of the cavity wall of the first cavity segment can support the first battery, securing it within the battery fixing structure while preventing contact between the first battery and the second support surface, thus enabling proper installation of the first battery.

[0074] In some embodiments, a battery end cap is also included, which covers the opening and is connected to the body. The battery end cap protects the opening from external dust or other impurities entering the housing cavity through the opening, causing battery contamination and affecting battery life, and also prevents the battery from detaching from the opening and causing damage.

[0095] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0096] Figure 1 This is a schematic diagram of a cleaning device equipped with a first battery, provided in an embodiment of this application.

[0097] See Figure 1This application provides a cleaning device, which includes a body 1, which can be understood as the housing of the cleaning device 100. The side of the body 1 facing the surface to be cleaned can be understood as the bottom surface of the body 1. Along the height direction z of the body 1, the body 1 has a bottom surface and a top surface. The top surface of the body 1 can be understood as the side of the body 1 away from the surface to be cleaned. Any two of the front-back direction, the width direction y, and the height direction z of the body 1 are perpendicular to each other, and the forward direction x of the cleaning device 100 is parallel to the front-back direction of the body.

[0098] The cleaning device 100 also includes a walking assembly, which includes drive wheels that can be located on the side of the machine body 1 facing the surface to be cleaned. The drive wheels provide power to the machine body 1, enabling it to move and turn. For example, the drive wheels can be rollers.

[0099] The walking assembly also includes driven wheels, which can be located on the side of the machine body 1 facing the surface to be cleaned. When the drive wheels provide power to the machine body 1, the driven wheels can provide guidance and assistance to the machine body 1 during movement, thereby enhancing the stability of the cleaning equipment 100 during movement. For example, the driven wheels can be omnidirectional wheels.

[0100] It should be noted that the driven wheel and the drive wheel can be spaced apart in the forward direction x of the cleaning device 100. The specific positions of the driven wheel and the drive wheel on the body, as well as the connection method between the driven wheel and the drive wheel and the body 1, can be determined based on existing cleaning devices such as robotic vacuum cleaners, and will not be elaborated further here.

[0101] The cleaning equipment 100 also includes a cleaning module, which is located on the side of the body 1 facing the surface to be cleaned, i.e., the cleaning module is located on the bottom surface of the body 1, so that when the cleaning module is running relative to the body 1, it can contact the surface to be cleaned and perform sweeping or other cleaning operations on the surface to be cleaned.

[0102] Cleaning modules typically include operable cleaning components. The operation of the cleaning module relative to the main body 1 usually refers to the operation of the cleaning components relative to the main body 1. When the cleaning components operate relative to the main body 1, they contact the surface to be cleaned, thereby removing debris from the surface. For example, the cleaning components can be roller brushes. For example, debris can include paper scraps, hair, food crumbs, etc.

[0103] It is understandable that, based on the cleaning function implemented by the cleaning module, the cleaning module can also be called a cleaning module.

[0104] The cleaning device 100 also includes a battery 5, which is housed inside the body 1 via a battery fixing structure 2, located between the bottom and top surfaces of the body 1 along the height direction z. The battery 5 provides power to the cleaning device 100 to drive the drive wheels in the walking assembly, enabling the movement and steering of the body 1, and also provides power to other electrical components in the cleaning device 100. The battery 5 is electrically connected to the drive wheel motor and other electrical components via wires, continuously outputting electrical energy while the cleaning device 100 is operating.

[0105] See Figure 2 The cleaning device 100 may also include a mopping module 9. The mopping module 9 is located on the side of the body 1 facing the surface to be cleaned, and on the side of the cleaning module opposite to the battery 5, i.e., along the forward direction x of the cleaning device 100, the cleaning module is located between the battery 5 and the mopping module 9. When the mopping module 9 operates relative to the body 1, it can contact the surface to be cleaned and generate friction, mopping the surface to be cleaned, thus enabling the cleaning device 100 to have a mopping function.

[0106] Specifically, the mopping module 9 typically has a movable cloth. When the mopping module 9 is in operation relative to the body 1, the cloth comes into contact with the surface to be cleaned and generates friction to mop the surface.

[0107] Based on the different shapes of the mop cloths in the mopping module 9, the mopping modules 9 can be roughly divided into: disc mopping modules, roller mopping modules, and tracked mopping modules. The mop cloth in the disc mopping module is usually called a disc-type mop cloth. The mop cloth in the roller mopping module is usually a roller-type mop cloth. The mop cloth in the tracked mopping module is joined end-to-end, forming a flat, track-like structure, and is usually called a tracked mop cloth.

[0108] Compared to disc-type mops, roller and belt-type mops have advantages such as larger mopping area, stronger ground pressure, and the ability to mop along the edges, making them widely used in cleaning equipment 100. Roller and belt-type mops typically use at least one motor to drive the mop, thus completing the cleaning action (such as mopping).

[0109] Compared to disc-type cleaning cloths, roller-type and conveyor-type cleaning cloths take up more space in the machine body.

[0110] In existing cleaning equipment, batteries are typically in a relatively regular rhomboid or rectangular shape. Correspondingly, the battery fixing structure, in the cross-sectional direction parallel to the width direction (y) of the machine body, is also in a relatively regular rhomboid or rectangular hole. Furthermore, adding a mopping module 9 with a roller-type or tracked mop occupies a significant amount of space within the machine body, resulting in less space for the battery and other functional modules. Therefore, to ensure sufficient space for the battery and other functional modules, the overall size of the cleaning equipment needs to be increased accordingly. In addition, since the functional modules located next to the battery are usually not in a regular rectangular shape but rather irregular shapes, such as walking components or cleaning modules, gaps exist between the irregular shapes and the battery fixing structure. These gaps cannot be effectively utilized, leading to low internal space utilization and wasted space. Simultaneously, the regular battery shape makes it difficult to achieve an optimal fit with the irregular shapes, affecting the compactness of the internal space and further increasing the overall size of the cleaning equipment.

[0111] In view of this, this application provides a cleaning device, which includes a body, a first functional module, a second functional module, and a battery. Both the first and second functional modules are located on the side of the body facing the surface to be cleaned, and along the forward direction of the cleaning device, the first and second functional modules are located on opposite sides of the battery fixing structure. By placing the battery inside the body, in the height direction of the body, the projection of the battery overlaps with the projection of at least one of the first and second functional modules, effectively utilizing the spatial dimension in the height direction of the body and improving the space utilization rate of the body, thus facilitating the miniaturization design of the cleaning device. Alternatively, by improving the space utilization rate of the body, more functions can be designed for the cleaning device without affecting its size, thereby meeting users' needs for more functions in the cleaning device.

[0112] The structure of the cleaning equipment provided in the embodiments of this application will be further described below with reference to the accompanying drawings and examples.

[0113] Figure 2 for Figure 1 Cross-sectional view of the cleaning equipment in the AA direction.

[0114] See Figure 1 and Figure 2 The cleaning device 100 includes a body 1, and a battery fixing structure 2 is located inside the body 1. The cleaning device 100 also includes a first functional module 3 and a second functional module 4. The first functional module 3 and the second functional module 4 are both located on the side of the body 1 facing the surface to be cleaned, and along the forward direction x of the cleaning device 100, the first functional module 3 and the second functional module 4 are located on opposite sides of the battery fixing structure 2.

[0115] Specifically, the first functional module 3 and the second functional module 4 are functional modules located on both sides of the battery 5. Depending on the specific type of cleaning equipment 100, the specific structures of the first functional module 3 and the second functional module 4 can be flexibly configured. In this embodiment, the first functional module 3 can be a driven wheel assembly, etc., which is used to realize the steering and auxiliary movement functions of the body 1; the second functional module 4 can be a cleaning module, etc., which is used to perform floor cleaning operations (such as sweeping).

[0116] The surface to be cleaned is the surface that the cleaning equipment 100 will clean. Depending on the type of cleaning equipment 100, the surface to be cleaned can be a tile surface or a carpet surface, etc.

[0117] The cleaning device 100 includes a battery 5, which is housed within a battery fixing structure 2, thus placing the battery 5 within the main body 1. The battery fixing structure 2 can be understood as the mounting structure for the battery 5. The battery fixing structure 2 is located within the main body 1, between the bottom and top surfaces of the main body 1. The battery fixing structure 2 is connected to the bottom surface of the main body 1 to ensure overall stability.

[0118] Specifically, the battery 5 is housed within the battery fixing structure 2. At this time, in the height direction z of the body 1, the projection of the battery 5 overlaps with the projection of at least one of the first functional module 3 and the second functional module 4. This effectively utilizes the spatial dimension of the body 1 in the height direction z, allowing the battery 5 and at least one of the first functional module 3 and the second functional module 4 to form a spatial complement within the body 1. This ensures that the body 1 can provide independent installation space for the first functional module 3, the second functional module 4, and the battery 5, while also effectively utilizing the gap between the battery 5 and the first and second functional modules 3 and 4, thereby improving the space utilization rate within the body 1 (referred to as the space utilization rate of the body 1).

[0119] By improving the utilization rate of the internal space of the unit 1, the size of the unit 1 can be compressed, resulting in a more compact internal space layout, which is beneficial for the miniaturization of the cleaning device 100. Alternatively, by improving the utilization rate of the internal space of the unit 1, more functions of the cleaning device 100 can be designed without affecting its size, so as to meet users' needs for more functions of the cleaning device 100. For example, without affecting the size of the cleaning device 100, the unit 1 can provide sufficient installation space for the first functional module 3, the second functional module 4, the battery 5, and the mopping module 9 with a roller-type mop or a conveyor belt-type mop, so that the cleaning device 100 can not only have a sweeping function, but also a mopping function.

[0120] Depending on the type of cleaning device 100, the size and shape of the first functional module 3 and the second functional module 4 will vary. In some embodiments, depending on the different first functional module 3 and second functional module 4, the battery 5 may only have an overlapping area with the projection of the first functional module 3 in the height direction z of the body 1. Alternatively, the battery 5 may only have an overlapping area with the projection of the second functional module 4 in the height direction z of the body 1. Or, the battery 5 may have overlapping areas with the projections of both the first functional module 3 and the second functional module 4 in the height direction z of the body 1. In this way, while ensuring improved space utilization of the body 1, it is possible to adapt to various types of cleaning devices 100.

[0121] It should be noted that, in order to ensure that the projection of battery 5 overlaps with the projection of at least one of the first functional module 3 and the second functional module 4, the battery 5 in this embodiment is not a rhomboid or rectangular structure commonly found in existing cleaning devices. In this application, the side of battery 5 along the height z direction of the body 1 needs to be arranged at an angle, so that in the cross-sectional direction parallel to the height z direction of the body 1, the cross-sectional size of battery 5 will change from increasing to decreasing in the direction towards the surface to be cleaned. When the cross-sectional size of battery 5 decreases in the direction towards the surface to be cleaned, the end of battery 5 facing the surface to be cleaned is smaller, and the end away from the surface to be cleaned is larger. Therefore, when battery 5 is installed in the body 1, and when the tester tests the unassembled cleaning device 100, battery 5 will not detach from the body 1 due to its own structural characteristics.

[0122] See Figure 1 and Figure 2 In some embodiments, in the height direction z of the fuselage 1, the projections of the first functional module 3 and the second functional module 4 both coincide with at least a portion of the projection of the battery 5. This achieves a three-dimensional stacked layout of the battery 5 with the first functional module 3 and the second functional module 4 in the height direction z of the fuselage 1, which can further improve the utilization rate of the internal space of the fuselage 1.

[0123] Alternatively, by aligning the projections of the first functional module 3 and the second functional module 4 along the height z-axis of the body 1 with at least a portion of the projection of the battery 5, the gap between the battery 5 and the first and second functional modules 3 and 4 can be effectively utilized. This allows for the convenient installation of a larger capacity battery 5, or a more complex first and second functional module 3 and 4, within the same overall dimensions of the cleaning device 100.

[0124] See Figure 1 and Figure 2In some embodiments, the side of the body 1 facing the surface to be cleaned has a first mounting structure 6 and a second mounting structure 7. A first functional module 3 is disposed within the first mounting structure 6 and matches (is the same as or similar to) the shape of the first mounting structure 6. A second functional module 4 is disposed within the second mounting structure 7 and matches (is the same as or similar to) the shape of the second mounting structure 7.

[0125] Specifically, both the first mounting structure 6 and the second mounting structure 7 are located on the side of the body 1 facing the surface to be cleaned. The first mounting structure 6 is matched with the shape of the first functional module 3, and the second mounting structure 7 is matched with the shape of the second functional module 4. This ensures that the first functional module 3 can be securely fitted and fixed within the first mounting structure 6, and the second functional module 4 can be securely fitted and fixed within the second mounting structure 7. Furthermore, there will be no gaps between the first functional module 3 and the first mounting structure 6, or between the second functional module 4 and the second mounting structure 7, due to shape mismatch, thus avoiding waste of internal space in the body 1 and improving the utilization rate of internal space in the body 1.

[0126] Along the forward direction x of the cleaning device 100, the first mounting structure 6 and the second mounting structure 7 are located on opposite sides of the battery fixing structure 2. In the height direction of the body 1, the projections of the first mounting structure 6 and the second mounting structure 7 both coincide with at least a portion of the projection of the battery 5. This ensures that when the first functional module 3 is installed within the first mounting structure 6 and the second functional module 4 is installed within the second mounting structure 7, in the height direction z of the body 1, the projections of the first functional module 3 and the second functional module 4 both coincide with at least a portion of the projection of the battery 5. At this time, the battery 5 can spatially complement the first functional module 3 and the second functional module 4, further improving the space utilization of the body 1 and facilitating the miniaturization of the cleaning device 100.

[0127] Figure 5 for Figure 4 Cross-sectional view of the cleaning equipment in the BB direction. Figure 6 for Figure 5 A schematic diagram of the structure of a cleaning equipment with a battery end cap installed. Figure 7 for Figure 5 A schematic diagram of the structure of the cleaning equipment for removing the second battery.

[0128] See Figure 1 , Figure 2 and Figures 5 to 7In some embodiments, along the height z direction of the body 1, the end of the battery fixing structure 2 adjacent to the surface to be cleaned is a support end, and the end of the battery fixing structure 2 away from the surface to be cleaned is an inlet end, with an opening 2121 for the battery 5 to enter and exit. Along the forward direction x of the cleaning device 100, the size d1 of the inlet end is larger than at least part of the size d2 of the support end, resulting in the battery fixing structure 2 having a structure that is wider at the top and narrower at the bottom along the height z direction of the body 1. This allows the battery fixing structure 2 to have a larger operating space at the inlet end, facilitating the entry of the battery 5 through the opening 2121 into the battery fixing structure 2 for installation.

[0129] Meanwhile, the support end provides convenient support for the battery 5, allowing it to be securely fixed within the battery fixing structure 2. Furthermore, because the support end has a small size d2, securing the battery 5 within the battery fixing structure 2 does not affect the normal operation of the first functional module 3 and the second functional module 4 on both sides.

[0130] At least a portion of the inlet end is located on the side of the first mounting structure 6 and the second mounting structure 7 opposite to the surface to be cleaned. Furthermore, in the height direction of the body 1, the projections of the first mounting structure 6 and the second mounting structure 7 both coincide with at least a portion of the projection of the inlet end. By defining the position of the inlet end relative to the first mounting structure 6 and the second mounting structure 7, it can be ensured that in the height direction z of the body 1, the projections of the first mounting structure 6 and the second mounting structure 7 both coincide with a portion of the projection of the battery fixing structure 2. This facilitates that when the battery 5 is fixed within the battery fixing structure 2, in the height direction z of the body 1, the projections of the first mounting structure 6 and the second mounting structure 7 both coincide with at least a portion of the projection of the battery 5.

[0131] See Figure 1 , Figure 2 and Figure 7 In some embodiments, the side of the body 1 facing the surface to be cleaned is provided with a first receiving cavity 61 and a second receiving cavity 71. The first receiving cavity 61 corresponds to the first functional module 3 and forms a first mounting structure 6, so that when the first functional module 3 is disposed in the first receiving cavity 61, the first functional module 3 can be mounted on the body 1. The second receiving cavity 71 corresponds to the second functional module 4 and forms a second mounting structure 7, so that when the second functional module 4 is disposed in the second receiving cavity 71, the second functional module 4 can be mounted on the body 1. This allows the first functional module 3 and the second functional module 4 to have independent working spaces, which can avoid mutual interference between the first functional module 3 and the second functional module 4 during operation and facilitate independent maintenance.

[0132] Specifically, since the batteries in existing cleaning equipment are usually in a relatively regular rhomboid or rectangular structure, the corresponding battery fixing structure is a relatively regular rhomboid or rectangular through hole in the cross-sectional direction parallel to the width direction y of the machine body. To prevent the battery from coming out of the machine body, a bottom cover is usually set on the side of the battery fixing structure facing the surface to be cleaned.

[0133] However, when testers test the cleaning equipment before it is fully assembled, i.e., when the battery is only placed inside the body without a bottom cover, the battery is prone to coming out of the body and being damaged.

[0134] In view of this, see Figure 1 , Figure 2 and Figure 7 In some embodiments, based on the fact that the projection of the battery 5 overlaps with the projection of at least one of the first functional module 3 and the second functional module 4 in the height direction z of the body 1, the battery fixing structure 2 may also have a receiving cavity 21. The receiving cavity 21 has an opening 2121 located on the side of the receiving cavity 21 away from the surface to be cleaned, and the cavity wall of the receiving cavity 21 may have a support surface 22. When the battery 5 is placed in the receiving cavity 21 through the opening 2121, the support surface 22 can support the bottom of the battery 5, and the bottom of the battery 5 is positioned away from the opening 2121. In this way, placing the battery 5 in the receiving cavity 21 can provide an installation area for the battery 5 while protecting the battery 5.

[0135] Meanwhile, by supporting the bottom of the battery 5 with the support surface 22, when the tester tests the cleaning device 100 that is not fully assembled, the battery 5 can be prevented from falling out of the battery fixing structure 2 from the side of the receiving cavity 21 facing the surface to be cleaned and being damaged.

[0136] See Figure 2 , Figure 5 and Figure 7 In some embodiments, based on the fact that the projection of the battery 5 overlaps with the projection of at least one of the first functional module 3 and the second functional module 4 in the height direction z of the fuselage 1, the battery 5 may further include a first battery 51 or a second battery 52, with the first battery 51 and the second battery 52 having different shapes. The battery fixing structure 2 has a receiving cavity 21, and the cavity wall of the receiving cavity 21 has multiple supporting surfaces 22, which may include a first supporting surface 221 and a second supporting surface 222. When the first battery 51 is disposed in the receiving cavity 21, the first supporting surface 221 can support the first battery 51; when the second battery 52 is disposed in the receiving cavity 21, the second supporting surface 222 can support the second battery 52.

[0137] Since the first battery 51 and the second battery 52 are two types of batteries 5 with different shapes, the arrangement of supporting the first battery 51 with the first support surface 221 and supporting the second battery 52 with the second support surface 222 ensures that batteries 5 with different shapes (such as the first battery 51 and the second battery 52) can be stably supported within the battery fixing structure 2, avoiding shaking or displacement.

[0138] Furthermore, since the first battery 51 is supported by the first support surface 221 and the second battery 52 is supported by the second support surface 222, an adaptive structure is formed inside the accommodating cavity 21. When batteries 5 of different shapes are placed in the accommodating cavity 21, the accommodating cavity 21 can support batteries 5 of different shapes through different support surfaces 22 according to the different shapes of the batteries 5, thereby achieving compatibility with batteries 5 of different shapes. In this way, if the cleaning equipment 100 needs to replace the battery 5, there is no need to replace the entire body 1, which can reduce the production cost of the cleaning equipment 100.

[0139] The number of first support surfaces 221 can be one or more. Correspondingly, the number of second support surfaces 222 can be one or more. The first support surface 221 can be connected to the second support surface 222, and there can also be a gap between the first support surface 221 and the second support surface 222. This can be adapted according to actual needs.

[0140] See Figure 2 , Figure 5 and Figure 7 In some embodiments, the accommodating cavity 21 has an opening 2121 located on the side of the accommodating cavity 21 away from the surface to be cleaned, and the opening 2121 is used to allow the first battery 51 or the second battery 52 to pass through. When the first battery 51 is disposed in the accommodating cavity 21, the first supporting surface 221 supports the bottom of the first battery 51, and the bottom of the first battery 51 is disposed away from the opening 2121. When the second battery 52 is disposed in the accommodating cavity 21, the second supporting surface 222 supports the bottom of the second battery 52, and the bottom of the second battery 52 is disposed away from the opening 2121.

[0141] This design allows for easy and quick installation of both the first battery 51 and the second battery 52 through the open end 2121. Simultaneously, the first support surface 221 supports the bottom of the first battery 51, and the second support surface 222 supports the bottom of the second battery 52. ​​This prevents either the first battery 51 or the second battery 52 from detaching from the housing 21 and being damaged when the cleaning device 100 is not fully assembled and is being tested.

[0142] See Figure 2 , Figure 5 and Figure 7In some embodiments, when the first battery 51 is disposed within the receiving cavity 21, the other cavity walls of the receiving cavity 21 may not contact the first battery 51; similarly, when the second battery 52 is disposed within the receiving cavity 21, the other cavity walls of the receiving cavity 21 may not contact the second battery 52. ​​This ensures that the first support surface 221 is correspondingly disposed to the first battery 51, and the second support surface 222 is correspondingly disposed to the second battery 52, so that the battery fixing structure 2 can accurately adapt to and fix batteries 5 of different shapes disposed inside.

[0143] It should be understood that when the first battery 51 is disposed within the receiving cavity 21, the cavity walls of the receiving cavity 21, except for the first support surface 221, will not contact the first battery 51. Similarly, when the second battery 52 is disposed within the receiving cavity 21, the cavity walls of the receiving cavity 21, except for the second support surface 222, will not contact the second battery 52. ​​This avoids interference between the first battery 51 or the second battery 52 and other cavity walls within the receiving cavity 21. Furthermore, the first support surface 221 is correspondingly disposed to the first battery 51, and the second support surface 222 is correspondingly disposed to the second battery 52, so that the battery fixing structure 2 can accurately adapt to and fix batteries 5 of different shapes disposed inside.

[0144] See Figure 1 , Figure 2 , Figure 5 and Figure 7 In some embodiments, the first battery 51 and the second battery 52 both extend along the width direction y of the body 1, and the width direction y of the body 1 is perpendicular to the forward direction x of the cleaning device 100, so that the first battery 51 and the second battery 52 have a large side area in their own extension direction.

[0145] The first support surface 221 can support the side of the bottom of the first battery 51 in the extending direction. The second support surface 222 can support the side of the bottom of the second battery 52 in the extending direction. This arrangement, with the first support surface 221 supporting the side of the bottom of the first battery 51 in the extending direction and the second support surface 222 supporting the side of the bottom of the second battery 52 in the extending direction, enhances the fixing effect of the battery fixing structure 2 on the first battery 51 and the second battery 52. ​​Furthermore, this arrangement can also counteract the inertial force generated when the cleaning device 100 accelerates or decelerates, thereby improving the reliability of fixing the first battery 51 and the second battery 52.

[0146] See Figure 2 , Figure 5 and Figure 7In some embodiments, the shape of the first support surface 221 can match the shape of the side of the supported first battery 51, that is, the first battery 51 and the first support surface 221 have the same or similar shapes. This maximizes the contact area between the first battery 51 and the first support surface 221, ensuring the stability of the support. Furthermore, matching the shape of the first support surface 221 with the shape of the first battery 51 ensures that the contact portion between the first battery 51 and the first support surface 221 is subjected to uniform force, avoiding localized stress concentration, and thus extending the service life of the first battery 51.

[0147] See Figure 2 , Figure 5 and Figure 7 In some embodiments, the shape of the second support surface 222 can match the shape of the side surface of the supported second battery 52, that is, the second battery 52 and the second support surface 222 have the same or similar shapes. This maximizes the contact area between the second battery 52 and the second support surface 222, ensuring the stability of the support. Furthermore, the matching shape of the second support surface 222 with the shape of the second battery 52 ensures that the contact portion between the second battery 52 and the second support surface 222 is subjected to uniform force, avoiding local stress concentration, and thus extending the service life of the second battery 52.

[0148] See Figure 2 , Figure 5 and Figure 7 In some embodiments, in the cross-sectional direction parallel to the height direction of the fuselage 1, the cross-sectional shape of the first battery 51 is a first shape, and the cross-sectional shape of the second battery 52 is a second shape.

[0149] The first shape matches a triangle, the second shape matches a polygon, and the polygon has more than three sides.

[0150] Specifically, the first shape can be an isosceles triangle, an equilateral triangle, a right triangle, or other shapes that are the same as or similar to the structure of a triangle. For example, the first shape can also be a triangle structure with all three angles being arcs.

[0151] The second shape can be the same as or similar to a polygonal structure with any number of sides greater than three. If it is the same as the first shape, the interior angles of the second shape can also be arc angles.

[0152] This allows the first support surface 221 to support the first battery 51 that matches a triangle, and the second support surface 222 to support the second battery 52 that matches a polygon with more than three sides, so that the battery fixing structure 2 can be adapted to the installation of batteries 5 of different shapes, thereby reducing the production cost of the cleaning equipment 100.

[0153] See Figure 2 , Figure 5 and Figure 7 In some embodiments, when the first battery 51 or the second battery 52 is disposed in the accommodating cavity 21, one of the top corners of the first shape and the second shape are opposite to the opening 2121, and the top corner forms the bottom of the first battery 51 or the bottom of the second battery 52.

[0154] Specifically, since the vertices of triangles and polygons are all acute or obtuse angles formed by the intersection of two sides, or in some structures similar to triangles or polygons, the vertices can also be arc-shaped, meaning that the two sides connect to the two ends of the arc. Geometrically speaking, the cross-sectional shape of these vertices is a "V" shape.

[0155] In this embodiment, one of the apex corners of the first shape and the second shape faces away from the opening 2121, and the apex corner forms the bottom of the first battery 51 or the bottom of the second battery 52. ​​This arrangement ensures that when the first battery 51 or the second battery 52 is placed in the receiving cavity 21, the bottom of the first battery 51 or the bottom of the second battery 52 presents an inverted "V" shape. Due to its shape constraint, the first battery 51 or the second battery 52 is less likely to detach from the side of the body 1 facing the surface to be cleaned and be damaged. Furthermore, this also reduces the size of the battery fixing structure 2 at the bottom of the corresponding battery 5, so that the projection of the battery 5 in the height direction z of the body 1 overlaps with the projection of at least one of the first functional module 3 and the second functional module 4, thereby improving the utilization rate of the internal space of the body 1.

[0156] Meanwhile, since the first support surface 221 is used to support the bottom of the first battery 51 and the second support surface 222 is used to support the bottom of the second battery 52, when the cleaning device 100 is running, the component force perpendicular to the bottom slope of the first battery 51 or the second battery 52 will increase the positive pressure with the first support surface 221 or the second support surface 222, thereby generating greater friction, thus ensuring the stability of the battery 5 and preventing the battery 5 from coming out of the opening 2121 and being damaged.

[0157] See Figure 2 , Figure 5 and Figure 7 In some embodiments, in the height direction z of the body 1: the accommodating cavity 21 includes a first cavity segment 211 and a second cavity segment 212 that are interconnected. Compared to the second cavity segment 212, the first cavity segment 211 is disposed closer to the surface to be cleaned, so that in the height direction z of the body 1, the second cavity segment 212 is located above the first cavity segment 211.

[0158] Furthermore, along the direction from the second cavity segment 212 to the first cavity segment 211, the dimension of the first cavity segment 211 in the forward direction x of the cleaning device 100 (i.e., the width of the first cavity segment 211) decreases, so that the width of the first cavity segment 211 gradually decreases along the direction from the second cavity segment 212 to the first cavity segment 211. In the cross-sectional direction parallel to the height direction z of the body 1, the bottom of the two sides of the first cavity segment 211 has an inclined tendency to move closer to each other, so that the first cavity segment 211 can adapt to the inverted "V" shaped structure of the first battery 51 and the second battery 52 at the bottom, while reducing the size of the battery fixing structure 2 at the bottom of the corresponding battery 5, so that the first functional module 3 and the second functional module 4 can be set close to the bottom of the battery 5, thereby improving the utilization rate of the internal space of the body 1.

[0159] Meanwhile, along the direction from the second cavity segment 212 to the first cavity segment 211, the size of the first cavity segment 211 in the forward direction x of the cleaning device 100 gradually decreases, so that the first cavity segment 211 can form a natural limiting structure and guiding structure to prevent the battery 5 from coming out of the first cavity segment 211.

[0160] In addition, a portion of the cavity wall of the first cavity section 211 can form a second support surface 222, so that when the second battery 52 is disposed in the accommodating cavity 21, a portion of the cavity wall of the first cavity section 211 can support the second battery 52 and fix the second battery 52 in the battery fixing structure 2.

[0161] See Figure 2 , Figure 5 and Figure 7 In some embodiments, a portion of the cavity wall of the first cavity segment 211 forms a first support surface 221. The first support surface 221 is located on the side of the second support surface 222 facing the surface to be cleaned, and when the first battery 51 is disposed in the receiving cavity 21, there is a gap between the first battery 51 and the second support surface 222. In this way, when the first battery 51 is disposed in the receiving cavity 21, a portion of the cavity wall of the first cavity segment 211 can support the first battery 51, fixing the first battery 51 in the battery fixing structure 2 while ensuring that the first battery 51 does not contact the second support surface 222, avoiding interference between the first battery 51 and the second support surface 222, thereby ensuring the normal installation of the first battery 51.

[0162] See Figure 2 , Figure 5 and Figure 7In some embodiments, the first cavity segment 211 may be provided with two second support surfaces 222. The two second support surfaces 222 are distributed on both sides of the second battery 52. ​​The first support surface 221 connects the two second support surfaces 222. This allows the second support surfaces 222 to form a symmetrical support structure when supporting the second battery 52, ensuring the stability of the second battery 52. ​​Furthermore, the first support surface 221 is connected to the two second support surfaces 222, so that while supporting the first battery 51, it can avoid the two second support surfaces 222, and the support surfaces 222 form a complete support structure, ensuring the fixation effect of the first battery 51 within the battery fixing structure 2, and at the same time, allowing the load of the battery 5 to be evenly transmitted to the cavity wall of the accommodating cavity 21.

[0163] See Figure 2 , Figure 5 and Figure 7 In some embodiments, the portion of the first cavity segment 211 forms the support end of the battery fixing structure 2 to support the battery 5 and ensure the stability of the battery 5. An opening 2121 is provided on the side of the second cavity segment 212 away from the first cavity segment 211, and the portion of the second cavity segment 212 forms the opening 2121 end of the battery fixing structure 2 to facilitate the installation of the battery 5.

[0164] Figure 3 for Figure 2 A schematic diagram of the structure of a cleaning equipment with a battery end cap installed. Figure 4 This is a schematic diagram of a cleaning device equipped with a second battery, provided in an embodiment of this application.

[0165] See Figure 3 , Figure 6 and Figure 7 In some embodiments, the cleaning device 100 may further include a battery end cap 8. The battery fixing structure 2 has a receiving cavity 21 with an opening 2121 for the battery 5 to pass through. The battery end cap 8 covers the opening 2121 and is connected to the body 1.

[0166] Specifically, the accommodating cavity 21 serves as the space for housing the battery 5, and has an opening 2121 at the top for the battery 5 to enter and exit. The battery end cap 8 is used to cover the opening 2121 to prevent external dust or other impurities from entering the accommodating cavity 21 through the opening 2121, causing contamination of the battery 5 and affecting its service life. It also prevents the battery 5 from coming out of the body 1 through the opening 2121.

[0167] The battery end cap 8 can be detachably or rotatably connected to the body 1, for example, by means of screws. This embodiment does not impose any restrictions on this.

[0168] It should be noted that a sealing strip can also be provided on the side of the battery end cover 8 facing the receiving cavity 21. When the battery end cover 8 covers the opening 2121, the sealing strip is squeezed between the battery end cover 8 and the periphery of the opening 2121 to prevent external sewage or other small impurities from entering the receiving cavity 21 through the gap between the battery end cover 8 and the opening 2121 and affecting the normal use of the battery 5.

[0169] See Figures 2 to 6 In some embodiments, the battery fixing structure 2 has heat dissipation holes 23, which are connected to the interior of the battery fixing structure 2.

[0170] During the operation of battery 5, heat is inevitably generated due to the electrochemical reactions inside battery 5 and the resistive effect during current transmission. As the cleaning equipment 100 continues to operate, heat gradually accumulates inside the battery fixing structure 2 and on the surface of battery 5, causing the temperature of battery 5 to rise continuously. This accelerates the aging of the chemical substances inside battery 5 and shortens its lifespan. Simultaneously, the increased temperature leads to increased internal resistance of battery 5, affecting discharge performance and posing a safety hazard.

[0171] In this embodiment, the heat dissipation holes 23 allow the heat from the battery 5 inside the battery fixing structure 2 to be dissipated through air convection, while simultaneously introducing cooler external air to create a continuous airflow circulation. This effectively reduces the operating temperature of the battery 5, keeping it within its optimal operating temperature range. This ensures stable performance of the battery 5, extends its lifespan, and improves the safety and reliability of the entire system.

[0172] The heat dissipation holes 23 can be located at positions corresponding to the bottom of the accommodating cavity 21 and the battery 5, or they can be located at other positions within the accommodating cavity 21. There can be one or more heat dissipation holes 23. Multiple heat dissipation holes 23 can be arranged in a uniform and spaced array within the battery fixing structure 2. The location, number, and size of the heat dissipation holes 23 can be adaptively selected according to actual needs; in this application, the location and number of heat dissipation holes 23 are not limited.

[0173] See Figures 2 to 6 In some embodiments, a buffer (not shown) is also included, which is disposed within the battery fixing structure 2 and sandwiched between the battery fixing structure 2 and the battery 5. This allows the buffer to absorb vibrations generated by the cleaning device 100 during operation, thereby protecting the battery 5 from damage.

[0174] The buffer element can be selected adaptively according to actual needs. For example, the buffer element can be made of elastic rubber material or use silicone pads; this embodiment does not impose any restrictions on this.

[0175] See Figures 2 to 6 For example, the first functional module 3 may include a driven wheel assembly, and the second functional module 4 may include a cleaning module.

[0176] The driven wheel assembly serves as a guide for the body 1 during movement, enhancing the stability of the cleaning device 100. The cleaning module is used to clean the surface to be cleaned, such as by mopping or sweeping. This allows for efficient use of the internal space of the body 1, enabling the installation of the driven wheel assembly, cleaning module, and battery 5 on the body 1. Furthermore, it allows the cleaning device 100 to perform both cleaning and movement functions while improving the utilization rate of the internal space of the body 1, facilitating the miniaturization of the cleaning device 100.

[0177] See Figures 2 to 6 In some embodiments, the cleaning device further includes a mopping module 9, which includes a roller-type mop or a conveyor belt-type mop. The mopping module 9 is located on the side of the body 1 facing the surface to be cleaned, and the mopping module 9 is located on the side of the cleaning module away from the battery 5.

[0178] The track mopping module and the roller brush mopping module have been described above and will not be repeated here.

[0179] The mopping module 9 is located on the side of the body 1 facing the surface to be cleaned, so that when the mopping module 9 is rotating relative to the body 1, it can contact the surface to be cleaned and mop it, thus enabling the cleaning device 100 to have a mopping function. Furthermore, since the battery 5 and at least one of the first functional module 3 and the second functional module 4 form a complementary space within the body 1, the space utilization of the body 1 is improved. In this way, without affecting the size of the cleaning device 100, the body 1 can provide sufficient installation space for the first functional module 3, the second functional module 4, the battery 5, and the mopping module 9 with a roller-type or conveyor-type mop, so that the cleaning device 100 has not only a sweeping function but also a mopping function.

[0180] The above describes a first type of cleaning device. In other embodiments, this application also provides a second type of cleaning device. In the second type of cleaning device, the projection of the battery 5 is not limited to the height direction z of the body 1, and the projection of at least one of the first functional module 3 and the second functional module 4 overlaps with the projection of the battery 5. The primary problem that the second type of cleaning device solves is that in existing cleaning devices, before assembly, the battery is easily detached from the side of the body facing the surface to be cleaned and damaged during testing.

[0181] Figure 8 An exploded view of the cleaning equipment provided in an embodiment of this application.

[0182] See Figure 7 and Figure 8 The second type of cleaning device also includes a body 1 and a battery 5. The body 1 has a battery fixing structure 2, which in turn has a receiving cavity 21. The receiving cavity 21 has an opening 2121 located on the side of the receiving cavity 21 facing away from the surface to be cleaned. The battery 5 is housed within the receiving cavity 21 of the battery fixing structure 2. The opening 2121 facilitates the installation of the battery 5.

[0183] The following text mainly describes the differences between the second type of cleaning equipment and the first type of cleaning equipment.

[0184] See Figure 7 and Figure 8 The bottom wall of the receiving cavity 21 is located on the side of the receiving cavity 21 closest to the surface to be cleaned, and the cavity wall of the receiving cavity 21 has a support surface 22. When the battery 5 is placed in the receiving cavity 21, the support surface 22 supports the bottom of the battery 5, and the bottom of the battery 5 is positioned away from the opening 2121. In this way, placing the battery 5 in the receiving cavity 21 can provide installation space for the battery 5 while protecting the battery 5.

[0185] Furthermore, by supporting the bottom of the battery 5 with the support surface 22, when the tester tests the cleaning device 100 before it is fully assembled, the battery 5 can be prevented from coming out of the battery fixing structure 2 from the side of the receiving cavity 21 toward the surface to be cleaned and being damaged.

[0186] See Figures 1 to 6 In the second type of cleaning device, in some embodiments, the cavity wall of the receiving cavity 21 may also have multiple support surfaces 22, including a first support surface 221 and a second support surface 222. When the first battery 51 is disposed in the receiving cavity 21, the first support surface 221 supports the bottom of the first battery 51. When the second battery 52 is disposed in the receiving cavity 21, the second support surface 222 supports the bottom of the second battery 52. ​​This creates an adaptive structure inside the receiving cavity 21, which can adapt to different battery shapes when placing batteries 5, thereby achieving compatibility and support for batteries 5 of different shapes. This avoids the possibility of batteries 5 detaching from the body 1 and causing damage due to shape differences, while also reducing the production cost of the cleaning device 100.

[0187] The first support surface 221, the second support surface 222, the first battery 51, the second battery 52, the bottom of the first battery 51 and the bottom of the second battery 52 have been described above and will not be repeated here.

[0188] It should be noted that, similar to the first cleaning device, in the second cleaning device, when the first battery 51 is disposed within the receiving cavity 21, the other cavity walls of the receiving cavity 21 may not contact the first battery 51; similarly, when the second battery 52 is disposed within the receiving cavity 21, the other cavity walls of the receiving cavity 21 may not contact the second battery 52, and the same technical effect can be achieved. Furthermore, the placement of the first support surface 221 at the bottom of the first battery 51 and the second support surface 222 at the bottom of the second battery 52 can adopt the same configuration as in the first cleaning device, producing the same beneficial effects, and will not be elaborated further here.

[0189] See Figure 2 , Figure 5 and Figure 7 In the second type of cleaning device, in some embodiments, when the first battery 51 is disposed within the receiving cavity 21, one of the apex portions of the first shape and the second shape are opposite to the opening 2121, and the apex portion forms the bottom of the first battery 51 or the bottom of the second battery 52. ​​The structure of the apex portion has been described above and will not be repeated here.

[0190] Due to the inherent shape limitations of the first battery 51 and the second battery 52, they are less likely to detach from the side of the body 1 facing the surface to be cleaned and be damaged. Furthermore, this reduces the size of the battery fixing structure 2 at the bottom of the corresponding battery 5, allowing the first functional module 3 and the second functional module 4 to be positioned close to the bottom of the battery 5. This ensures that, in the height direction z of the body 1, the projection of the battery 5 overlaps with the projection of at least one of the first functional module 3 and the second functional module 4, improving the utilization of the internal space of the body 1 and also facilitating the miniaturization of the cleaning device 100.

[0191] See Figure 2 , Figure 5 and Figure 7In the second type of cleaning device, in some embodiments, the accommodating cavity 21 also includes a first cavity segment 211 and a second cavity segment 212 that are interconnected. The setting position and size design of the first cavity segment 211 and the second cavity segment 212 are the same as those in the first type of cleaning device, and will not be repeated here. The beneficial effects produced are also the same, and a portion of the cavity wall of the first cavity segment 211 can also form a second support surface 222. This allows the first cavity segment 211 to adapt to the inverted "V" shaped structure at the bottom of the first battery 51 and the second battery 52, while reducing the size of the battery fixing structure 2 at the bottom of the corresponding battery 5, so that the first functional module 3 and the second functional module 4 can be set close to the bottom of the battery 5, improving the utilization rate of the internal space of the body 1. At the same time, by setting a portion of the cavity wall of the first cavity segment 211 to form a second support surface 222, it is also possible that when the second battery 52 is placed in the accommodating cavity 21, a portion of the cavity wall of the first cavity segment 211 can support the second battery 52 and fix the second battery 52 in the battery fixing structure 2.

[0192] See Figure 2 , Figure 5 and Figure 7 In the second type of cleaning device, in some embodiments, a portion of the cavity wall of the first cavity segment 211 can also form a first support surface 221, which is also located on the side of the second support surface 222 facing the surface to be cleaned. Furthermore, when the first battery 51 is disposed within the accommodating cavity 21, there is a gap between the first battery 51 and the second support surface 222. This ensures that while the first battery 51 is fixed within the battery fixing structure 2, it also prevents contact between the first battery 51 and the second support surface 222, avoiding interference and thus enabling proper installation of the first battery 51.

[0193] It should be noted that in some embodiments, the second cleaning device also includes a battery end cap 8. The battery end cap 8 is positioned on the body 1 in the same way as in the first cleaning device, and the beneficial effects are the same. It will not be described again here.
