Description

TECHNICAL FIELD

[0001] The utility model relates to the field of domestic washing, cleaning, especially to a base station for cleaning machine and cleaning machine system. BACKGROUND

[0002] The existing cleaning machine (sweeper or mop) can automatically return to the base station for charging, cleaning and other actions after completing the cleaning work, and the cleaning machine is stored in the base station when the cleaning machine is not working. Since the base station in the prior art can usually only receive and store one cleaning machine, one cleaning machine is usually in one-to-one correspondence with one base station. However, in some cases, the user will use multiple cleaning machines for cleaning work at the same time, so it is necessary to provide the same number of base stations to store and recover the cleaning machines, but this will occupy a lot of space and does not meet the user's needs.

[0003] To solve the above technical problems, a cleaning machine working base station is disclosed in Chinese Patent Application No. CN202110965919.4 (Publication No. CN113749563A), which includes a case, a base plate, a lifting plate, and a lifting mechanism. The case is provided with a partition plate, which divides the space in the case into multiple upper and lower storage spaces for accommodating the cleaning machine. An opening is formed on one side of the case to communicate with the multiple storage spaces. The base plate is connected to the side of the case with the opening, and the lifting plate is arranged above the base plate. The lifting mechanism connects the base plate and the lifting plate, and drives the lifting plate to move up and down relative to the base plate, and allows the lifting plate to be in contact with the partition plate. Although the above working base station can accommodate multiple cleaning machines, it only considers the storage of cleaning machines and does not consider the charging and dust collection of multiple cleaning machines. Moreover, since the base station in the prior art usually only provides components for charging and dust collection of one cleaning machine, the base station cannot realize charging and dust collection of multiple cleaning machines. Therefore, further improvement is needed for the prior art. UTILITY MODEL CONTENTS

[0042] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0043] Example 1:

[0044] like Figures 1-8 As shown, this embodiment relates to a base station for a cleaning machine and a cleaning machine system having the base station. The cleaning machine in this embodiment is a robotic vacuum cleaner.

[0045] In this embodiment, the base station for the cleaning machine includes a base 1 and a lifting mechanism 2. The base 1 has a accommodating cavity 10, which has an opening 12 for the cleaning machine to enter. A dust inlet 101 is provided on the bottom wall of the accommodating cavity 10. The lifting mechanism 2 includes a lifting platform 21 for storing the cleaning machine and a driving mechanism 22 that is driven to the lifting platform 21. The lifting platform 21 can move up and down under the drive of the driving mechanism 22.

[0046] like Figure 2As shown, in this embodiment, the lifting mechanism 2 is located inside the accommodating cavity 10. The lifting platform 21 is provided with a dust collection port 211 that can communicate with the dust inlet 101 and the dust outlet a at the bottom of the cleaning machine, respectively. Under the drive of the driving mechanism 22, the lifting platform 21 has at least two states: In the first state, the lifting platform 21 moves to a first set position, the lifting platform 21 contacts the bottom wall of the accommodating cavity 10, and the dust collection port 211 on the lifting platform 21 communicates with the dust inlet 101 on the bottom wall of the accommodating cavity 10, specifically as follows: Figure 1 and Figure 2 As shown; in the second state, the lifting platform 21 moves to the second set position, the lifting mechanism 2 is hidden inside the accommodating cavity 10, the lifting platform 21 is separated from the bottom wall of the accommodating cavity 10, and the lower part of the accommodating cavity 10 can form a first storage cavity 102 for placing the cleaning machine, specifically as shown. Figure 6 and Figure 8 As shown.

[0047] like Figure 2 and Figure 6 As shown, the opening 12 of the accommodating cavity 10 is located adjacent to the bottom wall of the accommodating cavity 10, and the opening 12 of the accommodating cavity 10 is located on the front side of the first storage cavity 102. The accommodating cavity 10 also includes a second storage cavity 103 located above the first storage cavity 102. The second storage cavity 103 and the first storage cavity 102 are connected. In the second state, the lifting platform 21 is hidden in the second storage cavity 103. Figure 5 As shown, when the lifting platform 21 is hidden in the second storage cavity 103, a relatively closed space is formed between the lifting platform 21 and the drive mechanism 22 and the outer periphery of the base 1.

[0048] In this embodiment, the drive mechanism 22 includes a drive source 221, and the lifting mechanism 2 includes a support platform 23 for mounting the drive source 221. The support platform 23 is fixedly disposed within the accommodating cavity 10 and located above the lifting platform 21.

The opening of the placement area 212 faces forward, and the dust collection port 211 is provided on the bottom wall of the placement area 212.

[0049] The drive mechanism 22 also includes a linkage assembly 3, which includes N first linkages 31 that are hinged end to end in sequence and N second linkages 32 that are hinged end to end in sequence. N is a positive integer greater than or equal to 2. In this embodiment, N = 2. Of course, the value of N can also be adapted according to the height of the second storage cavity 103.

[0050] Each first link 31 and the corresponding second link 32 are arranged in a cross shape, and are rotatably connected at the intersection between each first link 31 and the corresponding second link 32; the other ends of the first links 31 at the head and the tail are respectively rotatably connected to the lifting platform 21 and the carrying platform 23, and the other ends of the first and last second links 32 are respectively constrained to slide on the lifting platform 21 and the carrying platform 23, and at least one of the second links 32 can be driven and connected to the drive source 221.

[0051] To achieve the sliding of the other ends of the first and last second links 32, as Figure 3 and Figure 4 shown, in this embodiment, the lifting platform 21 and the carrying platform 23 are respectively provided with first guide rods 33 extending in the front-rear direction, and each first guide rod 33 is sleeved with a sliding seat 34 that can slide along its extending direction, and the first and last second links 32 are respectively rotatably connected to the corresponding sliding seats 34.

[0052] To achieve the stable lifting of both ends of the lifting platform 21, there are two link assemblies 3 in this embodiment, and the two link assemblies are symmetrically arranged on both sides of the lifting platform 21. First guide rods 33 and sliding seats 34 are also correspondingly provided on both sides of the lifting platform 21; as Figure 4 shown, the carrying platform 23 is also U-shaped with an open orientation, and first guide rods 33 and sliding seats 34 are also correspondingly provided on both sides of the carrying platform 23. To achieve the synchronous lifting of the two link assemblies 3, as Figure 3 shown, the drive mechanism 22 further includes a third link 35 that is driven and connected to the drive source 221, and both ends of the third link 35 are respectively connected to the two link assemblies 3, and the third link 35 can move up and down under the drive of the drive source 221. In this embodiment, both ends of the third link 35 are respectively connected to the hinge joints between the corresponding two adjacent second links 32 in the two link assemblies 3. As Figure 3 shown, the third link 35 in this embodiment is horizontally arranged, and the center of the third link 35 protrudes to form a "ji" - shaped structure.

[0053] The drive source 221 in this embodiment is connected to the third link 35 through a transmission mechanism 4. The transmission mechanism 4 in this embodiment includes a screw rod 41, a screw nut 42, and a first transmission wheel 44, a second transmission wheel 45, and a transmission belt 46 provided on the carrying platform 23. Both the screw rod 41 and the power output shaft of the drive source 221 are vertically arranged, the upper end of the screw rod 41 is installed on the power output shaft of the drive source 221, and the specific installation method of the screw rod 41 and the power output shaft of the drive source 221 is: the first transmission wheel 44 is sleeved on the power output shaft of the drive source 221, the second transmission wheel 45 is constrained to the upper end of the screw rod 41, and the transmission belt 46 is wound around the outer peripheries of the first transmission wheel 44 and the second transmission wheel 45; the screw nut 42 is installed on the screw rod 41, and the third link 35 is fixedly connected to the screw nut 42.

[0054] At least one second guide rod 43 is also provided vertically on the side of the lead screw 41. One end of each second guide rod 43 is fixedly connected to the bearing platform 23. The third connecting rod 35 has an insertion hole 351 for each second guide rod 43 to pass through. Below the third connecting rod 35, there is a fixing seat 5 for the other end of each second guide rod 43 to be fixedly connected. The aforementioned second guide rods 43 guide the lifting and lowering of the third connecting rod 35. Figure 3 As shown, in this embodiment, there are two second guide rods 43, one on the left and one on the right, distributed on both sides of the lead screw 41. Figure 4 As shown, the fixing seat 5 is arranged vertically, and the top of the fixing seat 5 is connected to the bearing platform 23. The ends of each of the second guide rods 43 and lead screws 41 are constrained to the ends of the fixing seat 5.

[0055] To automatically control the lifting of the platform, a first position detection unit 61 for detecting the position of the third link 35 is provided on the support platform 23, and a second position detection unit 62 for detecting the position of the third link 35 is provided on the fixed base 5. Both the first and second position detection units 61 and 62 are electrically connected to a controller. The controller is configured to: when the controller receives the detection signal from the first position detection unit 61, determine that the lifting platform 21 has moved to a second preset position; when the controller receives the detection signal from the second position detection unit 62, determine that the lifting platform 21 has moved to a first preset position. The controller is also electrically connected to the drive source 221 and stops operating after receiving the detection signal from either the first or second position detection unit 61. In this embodiment... Figure 4 As shown, when the protruding portion of the third link 35 is detected by the second position detection unit 62, the drive source 221 is controlled to stop operating; as Figure 7 As shown, when the protruding part of the third link 35 is detected by the first position detection unit 61, the drive source 221 is also controlled to stop operating.

[0056] like Figure 5 As shown, the bottom of the support platform 23 is also equipped with a charging electrode 231 for charging the cleaning machine, such as... Figure 6 As shown, the first storage cavity 102 is also provided with a charging unit 7 that can charge the cleaning machine.

[0057] The two cleaning machines to be stored in the base station in this application are designated as the first cleaning machine 1a and the second cleaning machine 1b. The working process of the base station in this embodiment is as follows:

[0058] Initially, the base station stores a first cleaning unit 1a and a second cleaning unit 1b. At this time, the second cleaning unit 1b is stored in the first storage cavity 102, and the first cleaning unit 1a is stored in the second storage cavity 103, i.e.Figure 8 As shown in the figure; since the charging unit 7 is located on the rear wall of the first storage cavity 102, and the lifting platform also needs to occupy space, the overall size of the first cleaning machine 1a in this embodiment needs to be smaller than that of the second cleaning machine 1b so that the base station can accommodate the storage of two cleaning machines 1a.

[0059] When the user needs to use the second cleaning machine 1b, the second cleaning machine 1b is controlled to move out from the front opening of the first storage cavity 102 to perform cleaning work.

[0060] When the user needs to use the first cleaning machine 1a again, the drive mechanism 22 is first controlled to move, causing the lifting platform 21 to descend to the first set position. At this time, the lifting platform 21 descends until it contacts the bottom wall of the receiving cavity 10, i.e. Figure 1 In the state shown, the first cleaning machine 1a is controlled to move out from the front opening of the first storage cavity 102 to perform cleaning work;

[0061] When the first cleaning machine 1a needs to return to the base station, it first determines whether the second cleaning machine 1b is stored in the first storage cavity 102. If so, the second cleaning machine 1b is first removed from the first storage cavity 102; if not, the drive mechanism 22 is controlled to move, so that the lifting platform 21 descends to contact the bottom wall of the accommodating cavity 10. After the first cleaning machine 1a moves onto the lifting platform 21, the dust collection port 211 on the lifting platform 21 can connect with the dust inlet 101. Since the dust collection port 211 on the lifting platform 21 also connects with the dust inlet 101 on the accommodating cavity 10, that is, as... Figure 2 As shown in the diagram, the first cleaning machine 1a can now perform dust collection. After the dust collection is completed by the first cleaning machine 1a, the drive mechanism 22 is controlled to move, causing the lifting platform 21 to rise to the second set position, i.e., as shown in the diagram. Figure 6 The state shown; at this time, due to the retraction of the linkage assembly, the third linkage 35 approaches the support platform 23, and the first cleaning machine 1a on the lifting platform 21 can dock with the charging electrode 231 on the support platform 23 to be charged.

[0062] When the base station is in such a state Figure 6 In the state shown, as the lifting mechanism raises the lifting platform, the linkage assembly is also raised and hidden along with the lifting platform. When not in operation, the lifting mechanism is not exposed and will not be abnormally touched. At this time, the second cleaning machine 1b can return to the base station for charging and dust collection.

[0063] In this embodiment, the linkage assembly and lead screw not only provide lifting and lowering but also have guiding and positioning functions, so there is no need to set up a lifting guide rail. At the same time, the linkage assembly serves as a fixed support connector. When the lifting platform is raised to the predetermined position, the entire drive mechanism also retracts and hides inside the base station, reducing the possibility of being abnormally touched.

[0064] Example 2:

[0065] like Figure 9 and Figure 10 As shown, unlike Embodiment 1, the drive mechanism 22 in this embodiment further includes a linkage assembly 3, which includes a first linkage 31 and a second linkage 32. The first linkage 31 and the second linkage 32 are arranged in a cross shape, and the intersection of the first linkage 31 and the second linkage 32 is rotatably connected. The first end of the first linkage 31 is rotatably connected to the lifting platform 21, and the second end of the first linkage 31 is hinged to the bearing platform 23. The first end of the second linkage 32 is rotatably connected to the bearing platform 23, and the second end of the second linkage 32 is hinged to the lifting platform 21.

[0066] The first end of the first link 31 and the first end of the second link 32 are arranged symmetrically at the top and bottom, and the second end of the first link 31 and the second end of the second link 32 are arranged symmetrically at the top and bottom.

[0067] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
