Description

Technical Field

[0001] This disclosure relates to the field of connection structure technology for cleaning equipment and robotic arms, and in particular to a female connector, a male connector, a connection structure, and a cleaning equipment. Background Technology

[0002] With the widespread use of cleaning equipment, the functional requirements for cleaning equipment are also increasing, and some cleaning equipment will expand its functions by means of robotic arms. In order to ensure the mobility of cleaning equipment, its size is limited and its internal space is compact.

[0003] Existing cleaning equipment and robotic arms are fixedly installed, making disassembly and replacement inconvenient and hindering maintenance. Fixing the robotic arm inside the cleaning equipment would occupy internal space and limit its size, impacting its usability. While fixing the robotic arm to the top, protruding from the upper surface, would increase its size to accommodate various applications, it would also increase the overall height of the cleaning equipment, affecting its maneuverability in low-lying areas. Utility Model Content

[0004] This disclosure provides a female connector, a male connector, a connection structure, and a cleaning device to improve the technical problem of inconvenience in replacing robotic arms and cleaning devices when they are fixedly installed.

[0005] The first aspect of this disclosure provides a female connector configured to connect with a male connector in a mating mode. The female connector includes a first body portion, a recess, a first magnetic member, and a first terminal block. The first body portion is configured to connect with a cleaning device via a connector. The recess is disposed on the first body portion and configured to engage with a protrusion of the male connector, causing the female connector and the male connector to move synchronously. The first magnetic member is disposed on the first body portion and configured to magnetically fix it to the male connector. The first terminal block is configured to electrically connect with a second terminal block of the male connector in response to the mating of the recess and the protrusion.

[0006] The recessed portion of the female connector mates with the protruding portion of the male connector, allowing them to move synchronously, including synchronous rotation and / or synchronous oscillation. The first magnetic chuck of the female connector engages with the second magnetic chuck of the male connector, fixing them relatively in place. When the female and male connectors need to be separated, the user or other equipment applies a force greater than the attraction between the first and second magnetic chucks, disengaging them. Electrical connection is achieved through the engagement of the first and second terminals. This disclosed female and male connector allows for quick connection and disconnection, facilitating the assembly, disassembly, and replacement of the robotic arm and cleaning equipment. During routine cleaning operations, the robotic arm can be omitted, as it neither occupies internal space nor increases the height of the cleaning equipment, ensuring its mobility. When the functions of the robotic arm are needed, the cleaning equipment and the robotic arm can be quickly connected via a female connector and a male connector, enabling the cleaning equipment to perform the functions provided by the robotic arm, such as picking up and organizing items; or enabling the cleaning equipment to climb and expand its cleaning range.

[0007] In an exemplary embodiment of this disclosure, the connector includes a first mounting groove. The first mounting groove is disposed in a first main body portion, and a first magnetic member is mounted within the first mounting groove. The thickness of the first magnetic member is less than the depth of the first mounting groove; or, the thickness of the first magnetic member is greater than the thickness of the first mounting groove.

[0008] When the thickness of the first magnetic chuck is less than the depth of the first mounting groove, and the thickness of the second magnetic chuck is greater than the depth of the second mounting groove, in other words, the first magnetic chuck is recessed into the first mounting groove, and the second magnetic chuck protrudes from the second mounting groove. When the first and second magnetic chucks attract each other, the second magnetic chuck extends into the first mounting groove. When the first and second magnetic chucks attract each other, they will align due to the magnetic field. By extending the second magnetic chuck into the first mounting groove, it guides the mating of the recessed and convex parts, making it easier for the convex part to extend into the recess, thus achieving the mating of the female and male connectors.

[0009] Similarly, when the thickness of the first magnetic chuck is greater than the depth of the first mounting groove, the thickness of the second magnetic chuck is less than the depth of the second mounting groove. When the first and second magnetic chucks attract each other, they will align due to the magnetic field. By extending the first magnetic chuck into the second mounting groove, it guides the mating of the concave and convex parts, making it easier for the convex part to extend into the concave part, thus achieving the mating of the female and male connectors.

[0010] In an exemplary embodiment of this disclosure, the recess is an elongated recess. At least two recesses are provided, and the length directions of at least two recesses are perpendicular.

[0011] The elongated concave portion mates with the elongated convex portion. By ensuring that the lengths of at least two concave portions are perpendicular, it is guaranteed that the concave and convex portions have high load-bearing capacity in all directions when the female and male connectors move together, reducing the risk of damage to the concave and convex portions.

[0012] In an exemplary embodiment of this disclosure, the female connector includes a slot disposed at the end of the first body portion. The slot is configured to engage with a snap fastener of the male connector to prevent the male connector from disengaging from the female connector.

[0013] The slot of the female connector and the buckle of the male connector work together to prevent the male and female connectors from disengaging, ensuring the connection strength between the robotic arm and the cleaning equipment and reducing the risk of the robotic arm falling off.

[0014] In an exemplary embodiment of this disclosure, the connecting female head includes a guide portion disposed at the opening of the recess; the inner diameter of the guide portion gradually increases from one end near the recess to the other end away from the recess.

[0015] By setting a guide part, the connection between the female and male connectors is guided. When the female and male connectors are misaligned, the protrusion of the male connector abuts against the wall of the guide part. The force between the protrusion and the guide part aligns the protrusion with the concave part, and the protrusion can be accurately inserted into the concave part to realize the connection between the female and male connectors. The female and male connectors can move synchronously, such as swinging synchronously.

[0016] In an exemplary embodiment of this disclosure, a first magnetic member is disposed at the bottom of the recess.

[0017] When the convex part and the concave part are engaged, the first magnetic attractor and the second magnetic attractor attract each other, which makes it easier for the convex part to be inserted into the concave part and maintains the engagement between the convex part and the concave part.

[0018] In an exemplary embodiment of this disclosure, the bottom edge of the recess is provided with a first inclined surface, which is inclined in a clockwise or counterclockwise direction from the bottom of the recess toward the opening of the recess; the first inclined surface is configured to match the second inclined surface of the convex portion so that the convex portion moves closer to or further away from the recess when the convex portion and the recess are rotated relative to each other.

[0019] The bottom edge of the recess has a first inclined surface. When the convex part needs to separate from the recess, the first and second inclined surfaces rotate relative to each other, causing the convex part and the recess to rotate relative to each other and move in the separation direction. This separates the first and second magnetic components, allowing the female connector to separate from the male connector. The rotation required to separate the first and second magnetic components is less than the attraction force between them, making it easier for the first and second magnetic components to separate and facilitating the separation of the female connector from the male connector.

[0020] In an exemplary embodiment of this disclosure, a first terminal is disposed on the inner wall of the recess so as to cooperate with a second terminal disposed on the outer wall of the protrusion when the protrusion is inserted into the recess.

[0021] By arranging the first terminal on the inner wall of the recess, the electrical connection between the first and second terminals is achieved through the mating of the recess and the convex portion, facilitating the arrangement of the first and second terminals. Simultaneously, the recess also protects the first and second terminals, reducing the risk of damage from impacts.

[0022] A second aspect of this disclosure provides a male connector that, when configured in a mating mode, connects to a female connector. The male connector includes a second body portion, a protrusion, a second magnetic chuck, and a second terminal. The second body portion is configured to be movably connected to a robotic arm. The protrusion is configured to mate with a recess of the female connector, such that the protrusion and recess engage to allow the female connector and male connector to swing and / or rotate synchronously. The second magnetic chuck is configured to mate with a first magnetic chuck of the female connector, such that when the second magnetic chuck engages with the first magnetic chuck, the female connector and male connector are fixed together. The second terminal is configured to mate with a first terminal of the female connector, such that when the second terminal engages with the first terminal, an electrical connection is achieved.

[0023] The male connector of this invention has a protrusion that mates with the recess of the female connector, thereby achieving synchronous movement between the male and female connectors. This synchronous movement includes synchronous rotation and / or synchronous oscillation. The second magnetic component of the male connector mates with the first magnetic component of the female connector, fixing the male and female connectors relatively in place. When the male and female connectors need to be separated, the user or other equipment applies a force greater than the attraction between the first and second magnetic components, thus separating the male and female connectors. Electrical connection is achieved through the mating of the first and second terminals. The male and female connectors of this invention can be quickly connected and disconnected, facilitating the assembly, disassembly, and replacement of the robotic arm and cleaning equipment. During routine operations, the robotic arm can be omitted, as it neither occupies internal space nor increases the height of the cleaning equipment, ensuring its mobility. When the functions of the robotic arm are needed, the cleaning equipment and the robotic arm can be quickly connected via a female connector and a male connector, enabling the cleaning equipment to perform the functions provided by the robotic arm, such as picking up and organizing items; or enabling the cleaning equipment to climb and expand its cleaning range.

[0024] In an exemplary embodiment of this disclosure, the male connector includes a second mounting groove. The second mounting groove is disposed in the second main body portion, and a second magnetic member is mounted in the second mounting groove. The thickness of the second magnetic member is greater than the depth of the second mounting groove, such that when the male connector mates with the female connector, the second magnetic member is inserted into the first mounting groove of the female connector; or, the thickness of the second magnetic member is less than the thickness of the second mounting groove, such that when the male connector mates with the female connector, the first magnetic member of the female connector is inserted into the second mounting groove.

[0025] The second mounting groove facilitates the installation of the second magnetic component. When the thickness of the second magnetic component is greater than the depth of the second mounting groove, the thickness of the first magnetic component of the female connector is less than the depth of the first mounting groove. The male connector mates with the female connector. When the first and second magnetic components attract each other, the second magnetic component extends into the first mounting groove. When the first and second magnetic components attract each other, they align due to the magnetic field. By extending the second magnetic component into the first mounting groove, it guides the mating of the concave and convex parts, making it easier for the convex part to extend into the concave part, thus achieving the mating of the female and male connectors.

[0026] When the thickness of the second magnetic chuck is less than the depth of the second mounting groove, the thickness of the first magnetic chuck of the female connector is greater than the depth of the first mounting groove. When the male connector and the female connector mate, the first magnetic chuck and the second magnetic chuck will align with each other due to the magnetic field. By extending the first magnetic chuck into the second mounting groove, it guides the mating of the concave and convex parts, making it easier for the convex part to extend into the concave part, thus achieving the mating of the female connector and the male connector.

[0027] In an exemplary embodiment of this disclosure, the protrusion is an elongated protrusion; at least two protrusions are provided, and the length directions of at least two protrusions are perpendicular.

[0028] The elongated convex portion and the elongated concave portion work together. When the elongated convex portion is subjected to force in the width direction, it has a larger contact area, which reduces the risk of damage to the concave portion. When the elongated convex portion is subjected to force in the length direction, it has better load-bearing capacity, reducing the risk of damage to both the convex and concave portions. This ensures the load-bearing capacity and service life of the male and female connectors.

[0029] In an exemplary embodiment of this disclosure, the male connector includes a latch. The latch is rotatably disposed at the end of the second body portion and is configured to engage with a slot in the female connector to prevent the male connector from disengaging from the female connector.

[0030] The latch rotates into the slot to connect the latch and the slot, thus securing the male and female connectors together. When the male and female connectors need to be separated, the latch rotates out of the slot, allowing them to separate. The cooperation between the latch and the slot improves the stability of the connection between the male and female connectors and reduces the risk of them disengaging.

[0031] In an exemplary embodiment of this disclosure, the male connector includes a torsion spring disposed at a rotation shaft that is rotatably connected to the buckle and the second main body, so that the buckle engages in the slot when the male connector and the female connector are engaged.

[0032] The torsion spring applies force to the buckle, ensuring that the buckle remains engaged in the slot after mating with it, thus guaranteeing the connection strength between the male and female connectors and reducing the risk of them becoming detached.

[0033] In an exemplary embodiment of this disclosure, one end of the protrusion extending into the bottom of the recess is a first end, and the other end of the protrusion corresponding to the first end is a second end; a second magnetic member is disposed at the first end of the protrusion.

[0034] By placing the second magnetic attractor at the first end of the protrusion, the protrusion can easily extend into the recess when the second magnetic attractor is attracted to the first magnetic attractor.

[0035] In an exemplary embodiment of this disclosure, a mounting hole is provided at the first end of the protrusion, and a second magnetic member is mounted in the mounting hole.

[0036] In an exemplary embodiment of this disclosure, a plurality of ribs are provided in the mounting hole along the circumference of the mounting hole; a notch is provided on the side of the ribs near the first end, and the notches of the plurality of ribs form a mounting opening, into which the second magnetic member is inserted.

[0037] By combining mounting holes and ribs, the mass of the male connector can be reduced, making it easier for the drive mechanism to move the male connector.

[0038] In an exemplary embodiment of the present disclosure, the end of the protrusion is provided with a second inclined surface, which is inclined in a clockwise or counterclockwise direction from the second end to the first end; the second inclined surface is configured to match the first inclined surface of the recess so that the protrusion and the recess move closer or further apart when they rotate relative to each other.

[0039] When the male and female connectors need to disengage, the convex and concave portions rotate relative to each other in the disengagement direction, causing the first and second magnetic components to separate, thus separating the female and male connectors. The rotation required to separate the first and second magnetic components is less than the attraction force between them, making it easier for the magnetic components to separate and facilitating the separation of the female and male connectors.

[0040] In an exemplary embodiment of this disclosure, a second terminal is disposed on the outer wall of the protrusion so as to cooperate with a first terminal on the inner wall of the recess when the protrusion is inserted into the recess.

[0041] By arranging the first terminal on the inner wall of the recess, the electrical connection between the first terminal and the second terminal is achieved after the recess and the convex part cooperate. The recess can also protect the first terminal and the second terminal, reducing the risk of the first terminal and the second terminal being damaged by impact.

[0042] A third aspect of this disclosure provides a connection structure including a female connector of any one of the above-mentioned plurality of connectors and a male connector that matches the above-mentioned female connectors.

[0043] The disclosed connection structure includes a female connector and a male connector, which can be quickly assembled and disassembled. This connection structure is adaptable to cleaning equipment, facilitating the assembly, disassembly, and replacement of the robotic arm. Different robotic arms can be used in different scenarios to meet various usage requirements. The cleaning equipment can perform routine cleaning tasks without the robotic arm, ensuring its mobility in low-ceilinged spaces.

[0044] A fourth aspect of this disclosure provides a cleaning device, including a device body and a robotic arm. The device body includes a female connector according to any of the above-mentioned features, and the robotic arm includes a male connector that mates with the female connector; or the device body includes a male connector according to any of the above-mentioned features, and the robotic arm includes a female connector that mates with the male connector.

[0045] The cleaning equipment disclosed herein includes a main body and a robotic arm. The robotic arm and main body can be quickly assembled and disassembled via a male and female connector, facilitating robotic arm replacement. The main body can be fitted with different robotic arms to meet various usage requirements. The cleaning equipment can operate without the robotic arm during routine cleaning tasks, ensuring its mobility in low-ceilinged spaces.

[0046] In combination with existing technologies, the beneficial effects of this disclosure are as follows:

[0047] The recessed portion of the disclosed female connector mates with the protruding portion of the male connector, allowing the female and male connectors to move synchronously, including synchronous rotation and / or synchronous oscillation. The first magnetic element of the female connector engages with the second magnetic element of the male connector, fixing the female and male connectors relatively in place. When the female and male connectors need to be disengaged, the user or other equipment applies a force greater than the attraction between the first and second magnetic elements, thus disengaging the female and male connectors. Electrical connection is achieved through the engagement of the first and second terminals.

[0048] The disclosed female and male connectors allow for quick connection and disconnection, facilitating the assembly, disassembly, and replacement of the robotic arm and cleaning equipment. During routine cleaning operations, the robotic arm can be omitted, as it neither occupies internal space nor increases the height of the cleaning equipment, ensuring its mobility. When the robotic arm's functions are required, the cleaning equipment and the robotic arm can be quickly connected via the female and male connectors, enabling the cleaning equipment to perform the functions provided by the robotic arm, such as gripping and organizing items, or enabling the cleaning equipment to climb and expand its cleaning range.

[0070] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. This disclosure can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0071] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this disclosure. The drawings only show components related to this disclosure and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the shape, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0072] Numerous details are explored in the following description to provide a more thorough explanation of embodiments of the present disclosure. However, it will be apparent to those skilled in the art that embodiments of the present disclosure may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present disclosure.

[0073] It should be noted that the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity of description and are not intended to limit the scope of this disclosure. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of this disclosure.

[0074] The existing cleaning equipment and robotic arms are fixedly installed, which is inconvenient to disassemble, replace, and maintain. Furthermore, the robotic arm, which is always fixed to the cleaning equipment, occupies internal or external space, thus affecting the spatial layout of the cleaning equipment or the accessibility of low-lying areas.

[0075] In view of this, this disclosure provides a female connector 100, a male connector 200, a connection structure, and a cleaning device. The quick assembly and disassembly of the female connector 100 and the male connector 200 enables the rapid assembly and disassembly of the robotic arm 400 on the cleaning device. During routine operations, the robotic arm 400 can be left unattended, as it neither occupies internal space nor increases the height of the cleaning device, ensuring its mobility. When the functions of the robotic arm 400 are required, the cleaning device and the robotic arm 400 are quickly connected via the female connector 100 and the male connector 200, allowing the cleaning device to perform the functions provided by the robotic arm 400. The cleaning device can also be equipped with different robotic arms 400 depending on the scenario; for example, the robotic arm 400 can be used to grip and organize items, or to enable the cleaning device to climb, expanding its cleaning range.

[0076] Please see Figures 1 to 5 In some embodiments of the connection structure disclosed herein, the connection structure includes a female connector 100 and a male connector 200 that matches the female connector 100.

[0077] Please see Figure 2 The female connector 100 is used to connect with the male connector 200 in a mating mode. The female connector 100 includes a first body portion 110, a recess 120, a first magnetic member 130, and a first terminal 140. The first body portion 110 is connected to the cleaning equipment via a connector. The recess 120 is disposed on the first body portion 110 and is configured to mate with the protrusion 220 of the male connector 200, so that the female connector 100 and the male connector 200 move synchronously. The first magnetic member 130 is disposed on the first body portion 110 and is configured to be magnetically fixed to the male connector 200. The first terminal 140 is configured to be electrically connected to the second terminal 240 of the male connector 200 in response to the mating of the recess 120 and the protrusion 220.

[0078] The docking mode can be initiated by the cleaning device. In some embodiments, the female connector 110 is located inside the housing of the cleaning device when it is in the retracted state. The cleaning device issues a docking command to control the female connector 110 to extend from inside the housing to outside the housing, thereby connecting the female connector 110 with the male connector 200.

[0079] In some embodiments, the female connector 110 is always kept protruding from the housing. When the cleaning device issues a docking command, the first terminal responds to the docking of the recess 120 and the protrusion 220 and is electrically connected to the second terminal to enable the cleaning device to supply power to the robotic arm 400.

[0080] The first main body 110 is connected to the cleaning equipment via a connector. The connection between the first main body 110 and the cleaning equipment can be either a detachable connection or a non-detachable connection.

[0081] In some embodiments, the connector is integrally formed with the first main body 110, and the connector 110 is fixedly installed on the cleaning equipment by the connector. The fixing method includes, but is not limited to, welding, gluing, and interference fit. The connector and the cleaning equipment can have different connection positions. For example, the connector is fixedly installed on the housing of the cleaning equipment so that the connector 110 is kept outside the housing; the connector can be connected to the motor of the cleaning equipment so that the motor drives the connector to move, realizing the connector retracting into and unscrewing out of the housing.

[0082] In some embodiments, the connector can be a connection structure, for example, a mechanical connecting arm that connects the female connector 110 to the cleaning device. The mechanical connecting arm allows the female connector 110 to retract into the housing when in a retracted state, and extends the female connector 110 out of the housing in response to a docking mode.

[0083] Please see Figure 5 The male connector 200, when used in docking mode, connects to the female connector 100. The male connector 200 includes a second body portion 210, a protrusion 220, a second magnetic chuck 230, and a second terminal block 240. The second body portion 210 is movably connected to the robotic arm 400. The protrusion 220 is configured to mate with the recess 120 of the female connector 100, allowing the female connector 100 and the male connector 200 to move. The second magnetic chuck 230 is configured to mate with the first magnetic chuck 130 of the female connector 100, fixing the female connector 100 and the male connector 200 together when the second magnetic chuck 230 mates with the first magnetic chuck 130. The second terminal block 240 is configured to mate with the first terminal block 140 of the female connector 100, enabling electrical connection when the second terminal block 240 mates with the first terminal block 140.

[0084] The docking mode can be initiated by the robotic arm 400. In the docking mode, the male connector 200 and the female connector 100 are connected.

[0085] In some embodiments, the robotic arm 400 is temporarily stored at the base station, and the docking mode can also be initiated by the base station. In response to the docking mode, the base station extends the male mechanical head 200 connected to the robotic arm 400 out of the base station.

[0086] In some embodiments, the male connector 200 remains outside the base station, and the second terminal 240 achieves electrical connection with the first terminal 140 when responding to a mating mode and engaging with the first terminal 140.

[0087] The protrusion 220 of the male connector 200 and the recess 120 of the female connector 100 are engaged in the same manner. The protrusion 220 and the recess 120 mainly bear the force that enables the male connector 200 and the female connector 100 to move synchronously, thereby realizing the synchronous movement of the female connector 100 and the male connector 200. The synchronous movement includes synchronous rotation and / or synchronous swing, thereby enabling the cleaning equipment to drive the robotic arm 400 to move, so as to realize the function of the robotic arm 400.

[0088] The outer wall of the protrusion 220 matches the inner wall of the recess 120, allowing the protrusion 220 and the recess 120 to engage. The shapes of the protrusion 220 and the recess 120 include, but are not limited to, cylindrical, square, and irregular cylindrical shapes. For example, if the protrusion 220 is cylindrical, the connecting female head 100 and the connecting male head 200 can achieve synchronous oscillation; if the protrusion 220 is square, the connecting female head 100 and the connecting male head 200 can achieve synchronous oscillation and synchronous rotation.

[0089] The second magnetic component 230 of the male connector 200 cooperates with the first magnetic component 130 of the female connector 100, fixing the female connector 100 and the male connector 200 relatively in place. When the female connector 100 and the male connector 200 need to be disconnected, a force greater than the attraction between the first magnetic component 130 and the second magnetic component 230 can be applied by the user, cleaning equipment, base station, or other equipment, thus separating the female connector 100 from the male connector 200. The connection and disconnection of the male connector 200 and the female connector 100 is simple and convenient, enabling rapid assembly and disassembly of the male connector 200 and the female connector 100, and consequently, rapid assembly and disassembly of the robotic arm 400 and the cleaning equipment. This allows for the selection of whether or not to carry the robotic arm 400 according to the needs of the scenario, and also allows for the replacement of different robotic arms 400 depending on the scenario.

[0090] The first magnetic component 130 and the second magnetic component 230 can both be magnets, or one of them can be a magnet and the other can be a component that can be attracted by a magnet.

[0091] The magnet can be an electromagnet or a permanent magnet. Preferably, the first magnetic attractor 130 and the second magnetic attractor 230 are both magnets, and both are permanent magnets, so as to facilitate the attraction between the first magnetic attractor 130 and the second magnetic attractor 230.

[0092] Electrical connection is achieved through the interaction of the first terminal 140 and the second terminal 240. This electrical connection can be used solely for transmitting signals to enable the cleaning equipment to drive the robotic arm 400 to perform corresponding tasks. The electrical connection can also be used by the main body 300 of the cleaning equipment to power the robotic arm 400, providing the necessary energy for the robotic arm 400 to perform its functions.

[0093] The second main body 210 is movably connected to the robotic arm. This movable connection can be a rotary connection, a sliding connection, or the like. Preferably, the second main body 210 is rotatably connected to the robotic arm. This movable connection between the second main body 210 and the robotic arm 400 allows for adjustment of the position of the connecting male connector 200 and the robotic arm 400. This allows the position of the second main body 210 to be adjusted while the arm remains stationary, facilitating the alignment and connection of the connecting male connector 200 and the connecting female connector 100.

[0094] The connection structure facilitates the quick connection and disconnection of the female connector 100 and the male connector 200, allowing for easy assembly, disassembly, and replacement of the robotic arm 400 with the cleaning equipment. During routine cleaning operations, the robotic arm 400 can be left out, as it neither occupies internal space nor increases the height of the cleaning equipment, ensuring its mobility. When the robotic arm 400's functions are required, it is quickly connected to the cleaning equipment via the female connector 100 and the male connector 200, enabling the cleaning equipment to perform the functions provided by the robotic arm 400. For example, the robotic arm 400 can be used to grip and organize items, or to climb, expanding the cleaning range of the equipment.

[0095] Please see Figure 2 In some embodiments, the female connector 100 includes a first mounting groove 150 disposed in the first main body portion 110. A first magnetic member 130 is mounted in the first mounting groove 150, and the thickness of the first magnetic member 130 is less than the depth of the first mounting groove 150.

[0096] The first mounting groove 150 provides space for the installation of the first magnetic component 130, and the first mounting groove 150 facilitates the positioning and installation of the first magnetic component 130. The fixing methods between the first magnetic component 130 and the first mounting groove 150 include, but are not limited to, adhesive bonding, snap-fit ​​bonding, and heat fusion bonding, so that the first magnetic component 130 and the first mounting groove 150 are fixed together.

[0097] If the thickness of the first magnetic member 130 is less than the depth of the first mounting groove 150, then after the first magnetic member 130 is installed in the first mounting groove 150, the first magnetic member 130 is recessed into the first mounting groove 150.

[0098] Please see Figure 5The male connector 200 includes a second mounting groove 250 disposed in the second main body portion 210. A second magnetic member 230 is mounted in the second mounting groove 250, and the size of the second magnetic member 230 corresponds to the size of the first magnetic member 130. The thickness of the second magnetic member 230 is greater than the depth of the second mounting groove 250, so that when the male connector 200 and the female connector 100 are engaged, the second magnetic member 230 is inserted into the first mounting groove 150 of the female connector 100.

[0099] The second mounting slot 250 provides space for the installation of the second magnetic component 230, facilitating the positioning and installation of the second magnetic component 230. The fixing methods between the second magnetic component 230 and the second mounting slot 250 include, but are not limited to, adhesive bonding, snap-fit ​​bonding, and heat fusion bonding, so that the second magnetic component 230 and the second mounting slot 250 are fixed together.

[0100] If the thickness of the second magnetic member 230 is greater than the depth of the second mounting groove 250, then when the second magnetic member 230 is installed in the second mounting groove 250, the second magnetic member 230 protrudes out of the second mounting groove 250.

[0101] When the first magnetic chuck 130 and the second magnetic chuck 230 attract each other and adhere, they align due to the magnetic field, thus guiding and positioning the male connector 200 and the female connector 100. The engagement between the protrusion 220 and the recess 120 occurs earlier than the initial adhesion and adsorption of the first magnetic chuck 130 and the second magnetic chuck 230. However, when there is a certain distance between the first magnetic chuck 130 and the second magnetic chuck 230, they are still in a dynamic alignment process, making direct alignment of the protrusion 220 and the recess 120 difficult. By inserting the second magnetic chuck 230 into the first mounting groove 150 and engaging with it, the protrusion 220 can be guided to align with the recess 120, allowing the protrusion 220 to extend into the recess 120 and connect the female connector 100 and the male connector 200.

[0102] In some embodiments, the thickness of the first magnetic member 130 is greater than the depth of the first mounting groove 150, and the first magnetic member 130 protrudes from the first mounting groove 150.

[0103] The thickness of the second magnetic member 230 is less than the depth of the second mounting groove 250, and the second magnetic member 230 is recessed into the second mounting groove 250.

[0104] When the first magnetic accumulator 130 and the second magnetic accumulator 230 attract each other, they will align with each other due to the magnetic field. By extending the first magnetic accumulator 130 into the second mounting groove 250, it guides the engagement of the recess 120 and the protrusion 220, making it easier for the protrusion 220 to extend into the recess 120, thus achieving the engagement of the female connector 100 and the male connector 200.

[0105] Please see Figure 2 In one embodiment, two first mounting slots 150 are provided, and two first magnetic attractors 130 are magnets, which are respectively installed in the two first mounting slots 150. The magnetic poles of the two first magnetic attractors 130 facing the outside of the connecting female connector 100 are opposite, that is, the N pole of one first magnetic attractor 130 faces the outside of the connecting female connector 100, and the S pole of the other first magnetic attractor 130 faces the outside of the connecting female connector 100.

[0106] Please see Figure 5 Correspondingly, two second mounting slots 250 are provided, and the two second magnetic components 230 are magnets, which are respectively installed in the two second mounting slots 250. The magnetic poles of the two second magnetic components 230 facing outwards from the male connector 200 are opposite to reduce the risk of reverse connection between the male connector 200 and the female connector 100.

[0107] In one embodiment, a first terminal 140 is disposed in the middle of the first main body 110, and two first magnetic members 130 are respectively disposed on both sides of the first terminal 140.

[0108] Please see Figure 2 In one embodiment, the recess 120 is an elongated recess 120. At least two recesses 120 are provided, and the length directions of at least two recesses 120 are perpendicular.

[0109] The elongated recess 120 mates with the elongated protrusion 220. By ensuring that the lengths of at least two recesses 120 are perpendicular, it is guaranteed that the recesses 120 and protrusions 220 have high load-bearing capacity in all directions when the female connector 100 and the male connector 200 move together, thereby reducing the risk of damage to the recesses 120 and protrusions 220.

[0110] The recesses 120 can be provided in two, three, four or more ways. Preferably, there are three recesses 120, with the length direction of two of the recesses 120 aligned with the height direction of the cleaning device. This improves the left-right swing frequency of the robotic arm 400. By aligning the length direction of the recesses 120 with the height direction of the cleaning device, the force-bearing area of ​​the recesses 120 can be increased, the pressure in the recesses 120 can be reduced, and the risk of damage to the connecting female head 100 can be decreased.

[0111] Please see Figure 5 The protrusion 220 is an elongated protrusion 220. At least two protrusions 220 are provided, and the number of protrusions 220 corresponds to the number of recesses 120. The length directions of at least two protrusions 220 are perpendicular.

[0112] The elongated protrusion 220 mates with the elongated recess 120. When subjected to forces in the width direction, the elongated protrusion 220 has a larger contact area, reducing the risk of damage to the recess 120. When subjected to forces in the length direction, the elongated protrusion 220 has better load-bearing capacity, reducing the risk of damage to the protrusion 220. By ensuring that the length directions of the two protrusions 220 are perpendicular, both good load-bearing capacity and the risk of damage to the protrusion 220 and the recess 120 are guaranteed, thus ensuring the load-bearing capacity and service life of the male connector 200 and the female connector 100.

[0113] For example, the two ends of the elongated recess 120 and the two ends of the elongated protrusion 220 are arc-shaped in the length direction, which improves stress concentration at the corners, reduces the risk of damage to the recess 120 and the protrusion 220, and improves the service life of the recess 120 and the protrusion 220.

[0114] Of course, as an alternative, only two elongated recesses can be provided, and the length direction of the two elongated recesses can be set in any direction.

[0115] Please see Figure 3 In one embodiment, the female connector 100 includes a slot 160 disposed at the end of the first main body portion 110. The slot 160 is configured to cooperate with the latch 260 of the male connector 200 to prevent the male connector 200 from disengaging from the female connector 100.

[0116] Please see Figure 5 The male connector 200 includes a latch 260, which is rotatably disposed at the end of the second main body 210. The latch 260 is configured to cooperate with the slot 160 of the female connector 100 to prevent the male connector 200 from disengaging from the female connector 100.

[0117] The latch 260 rotates into the slot 160, connecting the latch 260 and the slot 160, thus fixing the male connector 200 and the female connector 100 together. When the male connector 200 and the female connector 100 need to be separated, the latch 260 rotates out of the slot 160, thus separating the male connector 200 and the female connector 100. The cooperation between the latch 260 and the slot 160 improves the stability of the connection between the male connector 200 and the female connector 100 and reduces the risk of them disengaging.

[0118] In one embodiment, the male connector 200 includes a torsion spring disposed at a rotating shaft rotatably connecting the latch 260 and the second main body 210, so that when the male connector 200 and the female connector 100 are engaged, the latch 260 is engaged within the slot 160. For example, the latch 260 and the second main body 210 are rotatably connected via a rotating shaft, the torsion spring is sleeved on the rotating shaft, and both ends of the torsion spring abut against the latch 260 and the second main body 210 respectively, so that the latch 260 and the second main body 210 are kept in a relative state when the latch 260 is engaged within the slot 160.

[0119] By applying force to the buckle 260 through the torsion spring, the buckle 260 is kept engaged in the slot 160 after it is engaged with the slot 160, thus ensuring the connection strength between the male connector 200 and the female connector 100 and reducing the risk of the male connector 200 and the female connector 100 becoming detached.

[0120] When the latch 260 needs to disengage from the slot 160, an external force is applied to the latch 260 to cause it to rotate relative to the second main body 210. For example, a pressing device can be provided in the space of the temporary storage robotic arm 400 to disengage the latch 260 from the slot 160; a pressing device can also be provided on the cleaning equipment to disengage the latch 260 from the slot 160; or a pressing device can also be provided on the male connector 200 to disengage the latch 260 from the slot 160.

[0121] In one embodiment, the end of the buckle 260 is provided with a guide surface. When the buckle 260 abuts against the edge of the slot 160, the buckle 260 and the second main body 210 can rotate relative to each other so that the buckle 260 can be inserted into the slot 160.

[0122] Please see Figures 6 to 14 This disclosure also provides other connection structures, including a female connector 100 and a male connector 200 that matches the female connector 100. An exemplary structure of the female connector 100 and the male connector 200 is as follows:

[0123] Please see Figure 7 and Figure 8 A female connector 100 is used to connect to a male connector 200. The female connector 100 includes a first body portion 110, a recess 120, a first magnetic member, and a first terminal. The recess 120 is disposed on the first body portion 110 and is configured to engage with the protrusion 220 of the male connector 200, so that the female connector 100 and the male connector 200 move synchronously. The first magnetic member is disposed on the first body portion 110 and is configured to magnetically fix it to the male connector 200. The first terminal is configured to be electrically connected to the second terminal 240 of the male connector 200 in response to the engagement of the recess 120 and the protrusion 220.

[0124] Please see Figure 9 and Figure 10 The male connector 200 is used to connect to the female connector 100. The male connector 200 includes a second body portion 210, a protrusion 220, a second magnetic member 230, and a second terminal 240. The protrusion 220 is configured to mate with the recess 120 of the female connector 100, and the engagement of the protrusion 220 and the recess 120 allows the female connector 100 and the male connector 200 to move. The second magnetic member 230 is configured to mate with the first magnetic member of the female connector 100, so that the female connector 100 and the male connector 200 are fixed together when the second magnetic member 230 mates with the first magnetic member. The second terminal 240 is configured to mate with the first terminal of the female connector 100, so that an electrical connection is achieved when the second terminal 240 mates with the first terminal.

[0125] The protrusion 220 of the male connector 200 and the recess 120 of the female connector 100 are engaged in the same manner. The protrusion 220 and the recess 120 mainly bear the force that enables the male connector 200 and the female connector 100 to move synchronously, thereby realizing the synchronous movement of the female connector 100 and the male connector 200. The synchronous movement includes synchronous rotation and / or synchronous swing, thereby enabling the cleaning equipment to drive the robotic arm 400 to move, so as to realize the function of the robotic arm 400.

[0126] The outer wall of the protrusion 220 matches the inner wall of the recess 120 so that the protrusion 220 and the recess 120 are inserted into each other. The shapes of the protrusion 220 and the recess 120 include, but are not limited to, cylindrical, square, and irregular cylindrical shapes. For example, if the protrusion 220 is cylindrical, the connecting female head 100 and the connecting male head 200 can achieve synchronous swinging.

[0127] The second magnetic component 230 of the male connector 200 cooperates with the first magnetic component of the female connector 100, fixing the female connector 100 and the male connector 200 relatively in place. When the female connector 100 and the male connector 200 need to be disconnected, a force greater than the attraction between the first and second magnetic components 230 can be applied by the user, cleaning equipment, base station, or other equipment, thus separating the female connector 100 from the male connector 200. The connection and disconnection of the male connector 200 and the female connector 100 is simple and convenient, enabling rapid assembly and disassembly of the male connector 200 and the female connector 100, and consequently, rapid assembly and disassembly of the robotic arm 400 and the cleaning equipment. This allows for the selection of whether or not to carry the robotic arm 400 according to the needs of the scenario, and also allows for the replacement of different robotic arms 400 depending on the scenario.

[0128] The first magnetic attractor and the second magnetic attractor 230 can both be magnets, or one of them can be a magnet and the other can be a component that can be attracted by a magnet.

[0129] The magnet can be an electromagnet or a permanent magnet. Preferably, both the first magnetic attractor and the second magnetic attractor 230 are magnets, and both are permanent magnets, so as to facilitate the attraction between the first magnetic attractor and the second magnetic attractor 230.

[0130] Electrical connection is achieved through the interaction of the first terminal and the second terminal 240. This electrical connection can be used solely for transmitting signals to enable the cleaning equipment to drive the robotic arm 400 to perform corresponding tasks. The electrical connection can also be used by the main body 300 of the cleaning equipment to power the robotic arm 400, providing the energy required for the robotic arm 400 to perform its functions.

[0131] The connection structure facilitates the quick connection and disconnection of the female connector 100 and the male connector 200, allowing for easy assembly, disassembly, and replacement of the robotic arm 400 with the cleaning equipment. During routine cleaning operations, the robotic arm 400 can be left out, as it neither occupies internal space nor increases the height of the cleaning equipment, ensuring its mobility. When the robotic arm 400's functions are required, it is quickly connected to the cleaning equipment via the female connector 100 and the male connector 200, enabling the cleaning equipment to perform the functions provided by the robotic arm 400. For example, the robotic arm 400 can be used to grip and organize items, or to climb, expanding the cleaning range of the equipment.

[0132] Please see Figure 7 and Figure 8 In some embodiments, the protrusion 220 is cylindrical. The connector 100 includes a guide portion 170, which is disposed at the opening of the recess 120, and the inner diameter of the guide portion 170 gradually increases from one end near the recess 120 to the end away from the recess 120.

[0133] The connection between the female connector 100 and the male connector 200 is guided by the guide portion 170. When the female connector 100 and the male connector 200 are misaligned, the protrusion 220 of the male connector 200 abuts against the wall of the guide portion 170. The force between the protrusion 220 and the guide portion 170 aligns the protrusion 220 with the recess 120, allowing the protrusion 220 to be accurately inserted into the recess 120, thus achieving the connection between the female connector 100 and the male connector 200. The female connector 100 and the male connector 200 can move synchronously, for example, by swinging synchronously.

[0134] Please see Figure 9 and Figure 10 In some embodiments, the first magnetic element is disposed at the bottom of the recess 120.

[0135] The end of the protrusion 220 that extends into the bottom of the recess 120 is the first end, and the end of the protrusion 220 corresponding to the first end is the second end. The second magnetic attractor 230 is disposed at the first end of the protrusion 220.

[0136] When the protrusion 220 engages with the recess 120, the first magnetic attractor and the second magnetic attractor 230 attract each other, making it easier for the protrusion 220 to be inserted into the recess 120 and maintaining the engagement between the protrusion 220 and the recess 120.

[0137] Please see Figure 8 In some embodiments, the bottom edge of the recess 120 is provided with a first inclined surface 180, which is inclined in a clockwise or counterclockwise direction from the bottom of the recess 120 toward the opening of the recess 120. The first inclined surface 180 matches the second inclined surface 280 of the protrusion 220 so that the protrusion 220 moves closer to or further away from the recess 120 when the protrusion 220 and the recess 120 rotate relative to each other.

[0138] Please see Figure 9 The end of the protrusion 220 is provided with a second inclined surface 280, which is located at the first end. The second inclined surface 280 is inclined from the second end to the first end in a clockwise or counterclockwise direction. The second inclined surface 280 matches the first inclined surface 180 of the recess 120 so that the protrusion 220 and the recess 120 move closer or further apart when they rotate relative to each other.

[0139] When the male connector 200 is connected to the female connector 100, the second inclined surface 280 and the first inclined surface 180 are fully engaged. When the male connector 200 and the female connector 100 need to be separated, the second inclined surface 280 moves along the first inclined surface 180, or the first inclined surface 180 moves along the second inclined surface 280, by rotating the convex part 220 relative to the concave part 120. This causes the convex part 220 and the concave part 120 to move in the separation direction while rotating relative to each other, thereby separating the first magnetic component and the second magnetic component. The force between the first magnetic component and the second magnetic component weakens, and the convex part 220 and the concave part 120 can separate by relative linear movement or rotation plus linear movement. Rotation separates the first magnetic component from the second magnetic component. The force required for rotation is less than the attraction force between the first and second magnetic components, which is more conducive to the separation of the first magnetic component from the second magnetic component 230. This facilitates the separation of the female connector 100 from the male connector 200 and makes it easier to detach the robotic arm 400 from the main body 300 of the cleaning equipment.

[0140] Please see Figure 11 and Figure 13In some embodiments, the first end of the protrusion 220 is provided with a mounting hole 221, and the second magnetic member 230 is mounted in the mounting hole 221. The mounting hole 221 facilitates the installation of the second magnetic member 230.

[0141] Please see Figure 11 and Figure 13 In some embodiments, a plurality of ribs 222 are provided circumferentially within the mounting hole 221. A notch 223 is provided on the side of the rib 222 near the first end, and the notches 223 of the plurality of ribs 222 form a mounting opening, into which the second magnetic member 230 is inserted.

[0142] By setting ribs 222 and creating a notch 223 on the side of ribs 222 near the first end to form a mounting opening, the depth of the mounting hole 221 can be increased, thereby reducing the mass of the male connector 200. This facilitates the drive mechanism in moving the male connector 200 and reduces energy consumption. It also reduces the weight of the cleaning equipment, further reducing its energy consumption and improving its endurance. For the robotic arm 400 with climbing capabilities, weight reduction increases its load-bearing capacity during climbing and also reduces energy loss.

[0143] In some embodiments, a first terminal is disposed on the inner wall of the recess 120 so as to cooperate with a second terminal 240 disposed on the outer wall of the protrusion 220 when the protrusion 220 is inserted into the recess 120.

[0144] In some embodiments, a second terminal 240 is disposed on the outer wall of the protrusion 220 to engage with a first terminal on the inner wall of the recess 120 when the protrusion 220 is inserted into the recess 120.

[0145] By arranging the first terminal on the inner wall of the recess 120, the recess 120 and the protrusion 220 cooperate to achieve electrical connection between the first terminal and the second terminal 240, which facilitates the arrangement of the first terminal and the second terminal 240. At the same time, the recess 120 can also protect the first terminal and the second terminal 240, reducing the risk of the first terminal and the second terminal 240 being damaged by impact.

[0146] Please see Figure 1 and Figure 6 The cleaning equipment provided in this disclosure includes a main body 300 and a robotic arm 400, which are connected by any of the above-mentioned connection structures.

[0147] The main body 300 includes a female connector 100 of the connecting structure, and the robotic arm 400 includes a male connector 200 of the connecting structure. Alternatively, the main body 300 includes a male connector 200 of the connecting structure, and the robotic arm 400 includes a female connector 100 of the connecting structure. The cleaning equipment disclosed herein includes a main body 300 and a robotic arm 400. The male connector 200 and the female connector 100 allow for quick assembly and disassembly of the robotic arm 400 from the main body 300, facilitating the replacement of the robotic arm 400. The main body 300 can be fitted with different robotic arms 400 according to the needs of the scenario, meeting different usage requirements. The cleaning equipment can operate without the robotic arm 400 when performing routine cleaning tasks, ensuring the cleaning equipment's mobility in low-ceilinged spaces.

[0148] Please see Figure 3 In some embodiments, the device body 300 includes a motor 310 and a female connector 100. The motor 310 is connected to the female connector 100 via a connector. The movement of the motor 310 can drive the female connector 100 to move, so that the female connector 100 is exposed outside the device body 300 when it needs to be connected to the male connector 200, and is retracted into the device body 300 after the female connector 100 is disengaged from the male connector 200. This avoids damage to the female connector 100 from bumps and also avoids interference between the female connector 100 and other objects, which would restrict the movement of the cleaning device.

[0149] The cleaning equipment disclosed herein is a self-moving cleaning robot, which can be a mopping robot, a sweeping and mopping robot, a sweeping robot, etc.

[0150] The cleaning equipment also includes a conventionally configured walking system for driving the cleaning equipment to move on its own, enabling it to move freely across the surface to be cleaned.

[0151] To enable cleaning equipment to perform its cleaning function, the cleaning equipment must include at least a cleaning component. The cleaning component is used to clean the surface to be cleaned, and the cleaning method can be dry cleaning, wet cleaning, etc.

[0152] The cleaning equipment may also include a sensing system and a control system. The sensing system and control system are electrically connected. The sensing system can obtain the distance between the edge of the cleaning equipment and obstacles. The control system uses this distance to control the cleaning equipment and the robotic arm 400 to perform corresponding actions. For example, it can control the cleaning equipment to perform obstacle avoidance, edge cleaning, and return to the base station.

[0153] This disclosure includes a female connector 100, a male connector 200, a connection structure, and a cleaning device. Through the quick assembly and disassembly of the female connector 100 and the male connector 200, the robotic arm 400 on the cleaning device can be quickly assembled and disassembled from the device body 300. When the function of the robotic arm 400 is needed, the cleaning device and the robotic arm 400 are quickly connected via the female connector 100 and the male connector 200, allowing the cleaning device to perform the functions provided by the robotic arm 400. The cleaning device can also replace different robotic arms 400 according to different scenarios. For example, the robotic arm 400 can be used to grasp and organize items; it can also enable the cleaning device to climb, expanding its cleaning range. Therefore, this disclosure effectively overcomes some practical problems in the prior art, thus having high utilization value and practical significance.

[0154] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the claims of this disclosure.
