Description

Technical Field

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

[0002] Typical mobile robots (such as robotic vacuum cleaners) typically have a spring-loaded suspension on their drive wheels to improve traction and adapt to vibrations and obstacle crossing. This suspension ensures the drive wheels remain in contact with the ground when traversing obstacles, maintaining power. However, for robots with replaceable work modules, removing the work module from the main body while the robot is stationary reduces its weight. This causes the base to tilt, making module replacement inconvenient and negatively impacting the user experience. Utility Model Content

[0003] The main purpose of this utility model is to propose a host and a cleaning device, which aims to solve the problem of the base of the cleaning device tilting up when changing the working module.

[0004] To achieve the above objectives, the present invention provides a host unit for cleaning equipment, the cleaning equipment including an operation module, the host unit comprising:

[0005] The first base is used for mounting the working module, and the working module is detachably connected to the first base;

[0006] A drive assembly includes a second seat and a drive wheel mounted on the second seat. The second seat has a first end and a second end. The first end is rotatably connected to the first seat, and the second end is connected to the first seat via an elastic telescopic member. The working module is mounted on the first seat to keep the first seat in a non-tilted state, or the working module is not mounted on the first seat, and the elastic telescopic member allows the first seat to be in a tilted state.

[0007] The positioning structure has an unlocked state and a locked state. In the unlocked state, the first seat can swing relative to the second seat around the first end, and the first seat is in a tilted state or a non-tilted state. In the locked state, the first seat can be connected to the second seat through the positioning structure, and the positioning structure can position the second seat on the first seat, and the first seat is in a non-tilted state.

[0008] In one embodiment, the positioning structure includes a latch and a latch, one of which is disposed on the first base and the other is disposed on the second base;

[0009] When the buckle and the buckle are engaged, the positioning structure is in the locked state; when the buckle and the buckle are disengaged, the positioning structure is in the unlocked state.

[0010] In one embodiment, the buckle is rotatably connected to the first base body, the buckle has an unlock position and a locking position, and the buckle is provided with an operating part, which can switch the buckle between the unlock position and the locking position.

[0011] When in the unlocked position, the latch is separated from the buckle.

[0012] When in the locked position, the buckle can engage with the latch.

[0013] In one embodiment, the positioning structure further includes an adjustment component connected to the latch, the adjustment component enabling the latch to switch between the unlocked position and the locked position.

[0014] In one embodiment, the adjustment assembly includes a torsion spring, a connector, and a winding motor. The torsion spring connects the buckle and the first base, and the winding motor is connected to the operating part via the connector.

[0015] The winding motor rotates in one direction, and the operating part is pulled by the connector, which can make the buckle be in the unlocked position;

[0016] The winding motor rotates in the opposite direction, and the torsion spring enables the buckle to be in the locked position.

[0017] In one embodiment, the positioning structure further includes a positioning groove, a positioning shaft, and a driving member, wherein the driving member is drivingly connected to the positioning shaft;

[0018] One of the positioning groove and the positioning shaft is located in the second base and the other is located in the first base. The driving member can drive the positioning shaft to insert into or pull out of the positioning groove.

[0019] When the positioning shaft is pulled out of the positioning slot, the positioning structure is in the unlocked state;

[0020] When the positioning shaft is inserted into the positioning groove, the positioning structure is in the locked state.

[0021] In one embodiment, the positioning shaft and the driving member can constitute a driving member with a telescopic shaft;

[0022] And / or, the positioning shaft and the driving member are disposed on the second base body;

[0023] And / or, the positioning structure further includes a micro switch disposed on the first base, the micro switch being electrically connected to the driving component, the working module being able to trigger the micro switch, and the driving component being able to insert the positioning shaft into the positioning groove.

[0024] In one embodiment, the elastic telescopic member is configured as a tension spring, one end of which is connected to the second end and the other end of which is connected to the first base.

[0025] In one embodiment, the second seat has a third end, which is connected to the second seat through the positioning structure. The first seat is in a non-tilted state, with the first end and the second end located on the left side of the drive wheel, and the third end located on the right side of the drive wheel.

[0026] In one embodiment, the first seat is in a non-raised state, the first end is located below the horizontal center line of the drive wheel on the second seat, and the second end and the third end are located above the horizontal center line of the drive wheel on the second seat.

[0027] This utility model also proposes a cleaning device, including a main unit and an operating module, wherein the main unit is as described above, and the operating module is detachably connected to the first base.

[0028] The technical solution of this utility model adopts a positioning structure on the main unit. When the working module needs to be replaced, the positioning structure is in a locked state. In the locked state, the first base can be connected to the second base through the positioning structure. The positioning structure can position the second base on the first base. When the working module is removed from the first base, although the weight of the first base is reduced, the first base cannot rotate around the first end due to the restriction of the positioning structure, that is, the first base cannot be tilted. In this way, it is more convenient for the user to replace the working module, which can solve the problem of the base tilting when the working module is replaced in the prior art.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0045] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0046] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0047] Typical mobile robots (such as robotic vacuum cleaners) typically have a spring-loaded suspension on their drive wheels to improve traction and adapt to vibrations and obstacle crossing. This suspension ensures the drive wheels remain in contact with the ground when traversing obstacles, maintaining power. However, for robots with replaceable work modules, the robot is stationary when the work module is removed. Removing the work module reduces the robot's weight, and the spring-loaded suspension causes the base to tilt. This tilted base makes module replacement inconvenient and negatively impacts the user experience.

[0048] This utility model proposes a host for a cleaning device. The cleaning device includes two operation modules: a first operation module and a second operation module. Both the first and second operation modules can be used in conjunction with the host. The first operation module is used to clean carpets, and the second operation module is used to remove dust from carpets. Furthermore, according to usage needs, the user can select either the first or the second operation module. When the first or the second operation module is installed on a first base in the host, its own weight allows the first base to remain in a non-tilted state. The non-tilted state refers to the non-tilted state of the mobile robot when it is stationary and not working.

[0049] Please see Figure 1 , Figure 4 , Figure 5In one embodiment of this utility model, the host includes a first base 100, a drive assembly 200, and a positioning structure 300. The first base 100 is used for mounting the working module 400, which is detachably connected to the first base 100. Further, the working module 400 and the first base 100 are detachably connected via a snap-fit ​​structure 310 or a plug-in structure. The drive assembly 200 includes a second base 210 and a drive wheel 220 mounted on the second base 210. The drive assembly 200 also includes a drive motor connected to the drive wheel 220, which drives the drive wheel 220 to rotate. The second base 210 has a first end 211 and a second end 212. The first end 211 is rotatably connected to the first base 100, and the second end 212 is connected to the first base 100 via an elastic telescopic member 500. When the host is stationary and not working, the working module 400... The working module 400 is installed on the first base 100 to ensure that the first base 100 is in a non-tilted state. It can be understood that when the working module 400 is installed on the first base 100, its own weight acts on the first base 100, increasing its weight. At this time, when the elastic telescopic member 500 is stretched, the weight of the first base 100 can overcome the stretching force of the elastic telescopic member 500, and the first base 100 will not tilt; that is, the first base 100 is in a non-tilted state. When the main unit is stationary and not working, after the working module 400 is removed from the first base 100, i.e., the working module 400 is not installed on the first base 100, the weight of the first base 100 is reduced. The weight of the first base 100 cannot overcome the stretching force of the elastic telescopic member 500, and the elastic telescopic member 500 uses its stretching force to cause the first base 100 to rotate and tilt around the first end 211, i.e., the first base 100 is in a tilted state. It should be noted that when the main unit moves over obstacles or experiences vibrations, the first seat 100 may tilt up. However, due to the gravity of the working module 400, the first seat 100 will still fall down after tilting to a certain extent, changing from a tilted state to a non-tilted state. At the same time, when the main unit moves over obstacles, the elastic telescopic member 500 can make the second seat 210 rotate around the first end 211 relative to the first seat 100, so that the drive wheel 220 contacts the ground, thereby ensuring the driving force.

[0050] The positioning structure 300 has an unlocked state and a locked state. In the unlocked state, the first seat 100 can swing relative to the second seat 210 around the first end 211. The first seat 100 is either in a tilted state or a non-tilted state. It should be noted that when the working module 400 is installed on the first seat 100, the positioning structure 300 is in the unlocked state, and the first seat 100 is in a non-tilted state. When the working module 400 is not installed on the first seat 100, the positioning structure 300 is in the unlocked state, and the first seat 100 is in a tilted state. In the locked state, the first seat 100 can be connected to the second seat 210 through the positioning structure 300. The positioning structure 300 can position the second seat 210 on the first seat 100, and the first seat 100 is in a non-tilted state. Thus, in this embodiment, by setting a positioning structure 300 on the main unit, when the main unit is stationary and not working, and when the working module 400 needs to be replaced, the positioning structure 300 is in a locked state. In the locked state, the first base 100 can be connected to the second base 210 through the positioning structure 300. The positioning structure 300 can position the second base 210 on the first base 100. At this time, after the working module 400 is removed from the first base 100, although the weight of the first base 100 is reduced, the first base 100 cannot rotate around the first end 211 due to the restriction of the positioning structure 300, that is, the first base 100 cannot be tilted. In this way, it is more convenient for the user to replace the working module 400, which can solve the problem of the base tilting when the working module 400 is replaced in the prior art.

[0051] In some embodiments, the positioning mechanism may be a plug-in assembly that restricts the rotational connection between the first end 211 and the first seat 100. For example, the plug-in assembly includes a slot and a locking pin (not shown). Further, the first end 211 and the first seat 100 are connected by a pin. The pin is fixed to the first end 211 and rotatably connected to the first seat 100. At this time, a slot is provided on the pin, and a locking pin is provided on the first seat 100 corresponding to the slot. When the locking pin is inserted into the slot, the positioning structure 300 is in a locked state, that is, the pin and the first seat 100 are in a fixed state. Thus, when both ends of the pin are fixed to the first end 211 and the first seat 100 respectively, the first seat 100 cannot rotate relative to the first end 211, and therefore cannot be tilted, i.e., the first seat 100 is in a non-tilted state. Similarly, when the locking pin is pulled out of the slot, the pin can rotate relative to the first seat 100, i.e., the positioning structure 300 is in an unlocked state.

[0052] In one embodiment, unlike the aforementioned card slot and pin structure, reference is... Figure 5In this embodiment, the positioning structure 300 includes a latch 310 and a latching position 320. One of the latch 310 and the latching position 320 is located on the first base 100, and the other is located on the second base 210. That is, when the latch 310 is located on the first base 100, the latching position 320 is correspondingly located on the second base 210; when the latch 310 is located on the second base 210, the latching position 320 is correspondingly located on the first base 100. Further, when the latch 310 and the latching position 320 are engaged, the positioning structure 300 is in the locked state; when the latch 310 and the latching position 320 are disengaged, the positioning structure 300 is in the unlocked state. It should be noted that in some embodiments, the engagement and disengagement of the latch 310 can be achieved manually. For example, the latch 310 can be manually operated to engage with the locking position 320, thereby locking the positioning structure 300. Alternatively, the latch 310 can be manually operated to disengage from the locking position 320, thereby locking the positioning structure 300. It should be noted that when the main unit is equipped with the operating module 400, and the cleaning equipment is on a flat surface and stationary, the latch 310 and locking position 320 correspond correctly, and the latch 310 can smoothly engage with the locking position 320.

[0053] Further, in one embodiment, the latch 310 is rotatably connected to the first base 100. The latch 310 has an unlock position and a locking position, and an operating part 311 is provided on the latch 310. The operating part 311 allows the latch 310 to switch between the unlock position and the locking position. In the unlock position, the latch 310 is separated from the latch position 320; in the locking position, the latch 310 can be engaged with the latch position 320. It should be noted that the latch 310 can be manually switched between the unlock position and the locking position by operating the operating part 311 on the latch 310. When the latch 310 is in the unlock position, the latch 310 is separated from the latch position 320, and the positioning structure 300 is in the unlocked state. When the latch 310 is in the locking position, the latch 310 can be engaged with the latch position, and the positioning structure 300 is in the locked state. Furthermore, in some embodiments, the locking position is provided with a positioning part. When the latch 310 is in the locking position, the positioning part can position the latch 310 in the locking position. At this time, when the cleaning device moves, the latch 310 can always be in the locking position, so as not to affect the use of the cleaning device. The positioning part can adopt the following structure, for example, the positioning part includes an elastic gripper. When the latch 310 is in the locking position, the elastic gripper can clamp the latch 310, thereby restricting the latch 310 to the locking position. In other embodiments, the positioning part can be configured as an elastic pin. The latch 310 is provided with a slot corresponding to the elastic pin. When the latch 310 is in the locking position, the elastic pin is inserted into the slot, thereby restricting the latch 310 to the locking position. It should be noted that the operation part 311 of the latch 310 can be manually operated to make the latch 310 overcome the elastic force of the elastic pin, thereby squeezing the elastic pin out of the slot and releasing the elastic pin from restricting the latch 310.

[0054] In one embodiment, reference Figure 1 , Figure 2 , Figure 3Unlike the manual operation of the buckle 310 described above, the positioning structure 300 also includes an adjustment component 330, which is connected to the buckle 310 and enables the buckle 310 to switch between the unlocked position and the locked position. Further, in one embodiment, the adjusting assembly 330 includes a torsion spring 331, a connector 332, and a winding motor 333. The torsion spring 331 connects the buckle 310 and the first seat 100. The winding motor 333 is connected to the operating part 311 via the connector 332. When the winding motor 333 rotates in one direction, it pulls the operating part 311 via the connector 332, enabling the buckle 310 to be in the unlocked position. When the winding motor 333 rotates in another direction, the torsion spring 331 enables the buckle 310 to be in the locked position. Further, to improve the durability of the connector 332, the connector 332 is configured as a steel wire. Thus, by winding the steel wire with the winding motor 333, the steel wire pulls the buckle 310... The operating part 311 is subjected to a certain tension by the steel wire, causing the buckle 310 to overcome the elastic force of the torsion spring 331 and rotate around its own rotational connection with the first base 100, and rotate to the unlocked position. At this time, the buckle 310 is separated from the latch 320, and the positioning mechanism is in the unlocked state. Furthermore, the stopping of the winding motor 333 at this time allows the buckle 310 to remain in the unlocked position. When the winding motor 333 releases the steel wire, the buckle 310 rotates around its own rotational connection with the first base 100 under the action of the torsion spring 331 and rotates to the locked position. At this time, the buckle 310 can be engaged with the latch 320. Furthermore, when the steel wire does not apply tension to the operating part 311, the elastic force of the torsion spring 331 allows the buckle 310 to remain in the locked position. In some embodiments, the adjustment component 330 can be configured as an electric telescopic rod or other linear drive structure. When configured as an electric telescopic rod, the telescopic end of the electric telescopic rod is hinged to the operating part 311. The extension and retraction of the electric telescopic rod drives the buckle 310 to swing, thereby switching the buckle 310 between the unlocked and locked positions. The electric telescopic rod has a positioning function, which can position the buckle 310 in the unlocked or locked position.

[0055] In one embodiment, unlike the aforementioned snap-fit ​​310 and snap-fit ​​320 structures, the reference... Figure 7The positioning structure 300 further includes a positioning groove 340, a positioning shaft 350, and a driving member 360. The driving member 360 is driven to the positioning shaft 350. One of the positioning groove 340 and the positioning shaft 350 is located in the second base 210, and the other is located in the first base 100. The driving member 360 can drive the positioning shaft 350 to insert into or remove from the positioning groove 340. When the positioning shaft 350 is removed from the positioning groove 340, the positioning structure 300 is in the unlocked state. When the positioning shaft 350 is inserted into the positioning groove 340, the positioning structure 300 is in the locked state. Furthermore, in some embodiments, the drive element 360 can be a handle, which is used by a person to indirectly drive the positioning shaft 350. That is, the person operates the handle to insert or remove the positioning shaft 350 from the positioning slot 340. When the positioning shaft 350 is inserted into the positioning slot 340, the positioning structure 300 is in a locked state; when the positioning shaft 350 is removed from the positioning slot 340, the positioning structure 300 is in an unlocked state. In some embodiments, the drive element 360 can also be a linear drive structure, which drives the positioning shaft 350 to insert or remove from the positioning slot 340. Specifically, the movable end of the linear drive structure is connected to the positioning shaft 350. It should be noted that when the host is equipped with the working module 400 and the cleaning equipment is on a flat surface and stationary, the positioning slot 340 corresponds to the positioning shaft 350, and the positioning shaft 350 can be smoothly inserted and removed from the positioning slot 340.

[0056] In one embodiment, the positioning shaft 350 and the driving member 360 can constitute a driving member with a telescopic shaft (see...). Figure 7 In other words, the positioning shaft 350 and the drive element 360 are configured as a single component, in which case the drive shaft can be used as the telescopic shaft of this component. Furthermore, in some embodiments, this component can be an electrically operated telescopic rod.

[0057] In one embodiment (not shown), the positioning shaft 350 and the driving member 360 are disposed on the second base 210, and the positioning groove 340 is disposed on the first base 100. In some embodiments, the positioning groove 340 may be disposed on the second base 210, and the positioning shaft 350 and the driving member 360 may be disposed on the first base 100.

[0058] In one embodiment, the positioning structure 300 further includes a micro switch (not shown) disposed on the first base 100. The micro switch is electrically connected to the drive member 360. The working module 400 can trigger the micro switch. When the micro switch is triggered, the drive member 360 can insert the positioning shaft 350 into the positioning groove 340. It should be noted that during the initial disassembly stage, the working module 400 is not completely removed from the first base 100. At this time, the micro switch is triggered, and the drive member 360 can insert the positioning shaft 350 into the positioning groove 340. After the working module 400 is completely installed on the first base 100, the micro switch can send an electrical signal to the drive member 360, and the drive member 360 drives the positioning shaft 350 to pull it out of the positioning groove 340. It is understood that during the initial disassembly stage, part of the weight of the working module 400 still acts on the first base 100, which can still keep the positioning shaft 350 and the positioning groove 340 in relative position.

[0059] In one embodiment, reference Figure 4 , Figure 6 The elastic telescopic component 500 is configured as a tension spring, with one end connected to the second end 212 and the other end connected to the first seat 100. When the positioning structure 300 is in the unlocked state and the working module 400 is not installed on the first seat 100, the tension force of the tension spring allows the second end 212 to move toward the connection between the tension spring and the first seat 100. Since the first seat 100 is set on the ground, it is tilted upwards. When the positioning structure 300 is in the unlocked state and the working module 400 is installed on the first seat 100, when the cleaning equipment moves and encounters a bump or uneven surface, the tension force of the tension spring allows the second end 212 to move toward the connection between the tension spring and the first seat 100. At this time, the second seat 210 can swing around the first end 211 to ensure that the drive wheel 220 installed on the second seat 210 is always in contact with the ground, so that the drive wheel 220 can provide driving force to the cleaning equipment.

[0060] In one embodiment, reference Figure 5 The second seat 210 is provided with a third end 213, which is connected to the second seat 210 through the positioning structure 300. The first seat 100 is in a non-tilted state. The first end 211 and the second end 212 are located on the left side of the drive wheel 220, and the third end 213 is located on the right side of the drive wheel 220. That is to say, the positioning structure 300 is set on the right side of the drive wheel 220 along with the third end 213, which facilitates the structural layout and installation of the positioning structure 300.

[0061] In one embodiment, reference Figure 5The first seat 100 is in a non-tilted state. The first end 211 is located below the horizontal center line of the drive wheel 220 on the second seat 210. The second end 212 and the third end 213 are located above the horizontal center line of the drive wheel 220 on the second seat 210. This facilitates the installation of the positioning structure 300.

[0062] This utility model also proposes a cleaning device, see reference. Figure 1 The cleaning device includes a main unit and an operating module 400. The specific structure of the main unit is as described in the above embodiments. Since this cleaning device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The operating module 400 is detachably connected to the first base 100.

[0063] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
