Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a charging component and a cleaning robot. Background Technology

[0002] Most cleaning robots consist of a main robot unit and a supporting base station. After the main robot unit completes its work, it can enter the base station and connect the charging electrodes on the main robot unit and the charging electrodes on the base station to charge the main robot unit.

[0003] However, existing charging electrodes are usually located at the rear of the main unit. The charging electrodes are easily oxidized when exposed to air for a long time. Furthermore, when the main unit is working or cleaning the mop, moisture can easily splash onto the charging electrodes, causing electrochemical corrosion, which can lead to damage to the electrode components, poor charging contact, and reduced service life. Utility Model Content

[0004] Therefore, it is necessary to provide a charging component and a cleaning robot to address the above problems, so as to prevent damage to the electrode components and extend their service life.

[0005] This utility model provides a charging component for a cleaning robot, comprising: a docking member having a docking groove and a docking interface communicating with the docking groove, the docking member being disposed on the body; a first electrode being disposed in the docking groove and being electrically connected to the body of the cleaning robot; and a stop being disposed on the docking member and being movable relative to the docking member to open / close the docking interface.

[0006] In the aforementioned charging assembly, when the cleaning robot body needs charging, the control stop opens the interface, exposing the first electrode. The external charging electrode can then make electrical contact with the first electrode to charge the body. Once the body is fully charged, the external charging electrode is separated from the first electrode, and the control stop closes the interface, preventing the first electrode from being exposed. This avoids prolonged contact with air, which could lead to oxidation, and also prevents external moisture from splashing onto the first electrode, causing electrochemical corrosion. This protects the first electrode, prevents damage that could prevent charging, and extends its lifespan.

[0007] In one embodiment, the stop includes a first stop and a second stop disposed on opposite sides of the inner wall of the docking groove, with an openable opening formed between the first stop and the second stop.

[0008] This design simplifies the structure of the baffle, making it easier to open and close the opening, thus facilitating the opening and closing of the interface.

[0009] In one embodiment, both the first stop and the second stop are made of silicone.

[0010] With this design, the silicone part is soft and elastic, making it easy to open or close the opening. During charging, the silicone part can cover the outer periphery of the external charging electrode, preventing external moisture from splashing onto the first electrode and causing electrochemical corrosion, thereby protecting the first electrode.

[0011] In one embodiment, both the first stop and the second stop include an inclined surface facing the first electrode, extending from the opening to both sides of the inner wall of the docking groove, the inclined surface tilting toward the side away from the first electrode.

[0012] With this design, the inclined surface can improve the deformation capability of the first and second stops. After the external charging electrode exits the interface and opening, the first and second stops can be reset in time and close the opening.

[0013] In one embodiment, both the first and second stops are configured as baffles, which are rotatably disposed on the inner wall of the docking groove; the stop further includes a reset member disposed between the baffle and the inner wall of the docking groove, which deforms when the opening is opened.

[0014] With this configuration, the external charging electrode can push against the baffle, causing the baffle to move and open the opening, and the baffle can move in the opposite direction and close the opening under the action of the reset member.

[0015] In one embodiment, the charging assembly further includes an elastic element disposed on the side of the first electrode element opposite to the docking interface.

[0016] With this configuration, the elastic element ensures stable and reliable electrical contact between the external charging electrode and the first electrode, preventing poor contact that could lead to charging failure.

[0017] This utility model also provides a cleaning robot, including: a base station, including a base and a second electrode, the second electrode being disposed on the base and electrically connected to the base; and a host, including a body and a charging assembly as described above, wherein when the body is engaged with the base, the second electrode is in electrical contact with the first electrode.

[0018] With this configuration, when the main body needs to be charged, the main body is controlled to move to a position that mates with the base, so that the second electrode makes electrical contact with the first electrode to charge the main body.

[0019] In one embodiment, the base station further includes a positioning member protruding from the base, and the second electrode member is disposed at the end of the positioning member away from the base; when the body is engaged with the base, the positioning member is inserted into the docking groove through the docking interface so that the second electrode member makes electrical contact with the first electrode member.

[0020] This configuration places the second electrode on the positioning component, resulting in a better overall appearance of the body and base, and saving on component costs. When the base detects the charging signal, it can be determined that the body and base are successfully aligned. During the charging process, both the first and second electrode components are located in the docking groove, thereby protecting the first and second electrode components.

[0021] In one embodiment, the inner wall of the docking groove is provided with a first guide surface, which gradually slopes outward from the first electrode to the docking interface; and / or, the outer wall of the positioning member is provided with a second guide surface, which gradually slopes inward from the base to the second electrode.

[0022] This configuration allows the first and second guide surfaces to guide the positioning element, enabling it to move to a position that is fully aligned with the mating groove and insert into it, thus facilitating the positioning of the body and the base.

[0023] In one embodiment, the number of charging components is two, and the two charging components are arranged at intervals. The number of positioning members and the number of second electrode members are both two, and they are arranged in a one-to-one correspondence with the charging components. And / or, the main body is provided with a water storage tank and a water inlet communicating with the water storage tank, and the base is provided with a water outlet. When the positioning member is inserted into the docking groove through the interface, the water outlet is connected to the water inlet. And / or, the main body is provided with a dust storage box and a dust discharge port communicating with the dust storage box, and the base is provided with a dust collection port. When the positioning member is inserted into the docking groove through the interface, the dust collection port is connected to the dust discharge port.

[0024] This configuration, with two positioning components engaging with two docking slots respectively, improves the stability and reliability of the docking between the robot body and the base. While charging the robot body, it can also replenish the water tank inside the robot body or remove dust from the dust collection box inside the robot body, thereby improving the working efficiency and automation level of the cleaning robot.

[0039] Most cleaning robots consist of a main unit and a supporting base station. After completing its work, the main unit enters the base station, allowing its charging electrodes to connect with those on the base station for charging. However, existing charging electrodes are typically located at the rear of the main unit. These electrodes are prone to oxidation due to prolonged exposure to air, and moisture can easily splash onto them during operation or when cleaning the mop, causing electrochemical corrosion. This can damage the electrodes, lead to poor charging contact, and shorten the robot's lifespan.

[0040] To solve the above problems, such as Figures 1 to 7 As shown, this utility model first provides a charging component and a cleaning robot to prevent damage to the electrode components and extend their service life.

[0041] like Figures 1 to 3 As shown, specifically, the charging assembly includes a docking member 11, a first electrode member 12, and a stop member 13, wherein: the docking member 11 is provided with a docking groove 111 and a docking interface 112 communicating with the docking groove 111, and the docking member 11 is used to be installed on the body 14 of the cleaning robot; the first electrode member 12 is disposed in the docking groove 111 and is used to be electrically connected to the body 14; the stop member 13 is disposed on the docking member 11 and can move relative to the docking member 11 to open or close the docking interface 112.

[0042] In the charging assembly provided in this embodiment of the utility model, when the body 14 of the cleaning robot needs to be charged, the control stop 13 opens the interface 112, exposing the first electrode 12, allowing the external charging electrode to make electrical contact with the first electrode 12 to charge the body 14; after the body 14 is fully charged, the external charging electrode is separated from the first electrode 12, and the control stop 13 closes the interface 112, preventing the first electrode 12 from being exposed, thus avoiding long-term contact with air and easy oxidation, and also preventing external moisture from splashing onto the first electrode 12 and causing electrochemical corrosion, thereby protecting the first electrode 12, preventing damage to the first electrode 12 that would prevent charging, and extending the service life of the first electrode 12.

[0043] like Figure 4 As shown, the stop 13 includes a first stop portion 131 and a second stop portion 132 disposed opposite to each other on the inner wall of the mating groove 111, forming an openable and closable opening 133 between the first stop portion 131 and the second stop portion 132. When the first stop portion 131 and the second stop portion 132 open the opening 133, the opening 133 communicates with the mating interface 112, thereby opening the mating interface 112; when the first stop portion 131 and the second stop portion 132 close the opening 133, the mating interface 112 is closed. The stop 13 is embedded in the mating groove 111 and does not protrude from the mating member 11, thus avoiding increasing the overall volume of the body 14. Furthermore, the stop 13 has a simple structure, which facilitates the opening and closing of the opening 133, thereby facilitating the opening and closing of the mating interface 112.

[0044] In one embodiment, both the first stop 131 and the second stop 132 are made of silicone. The silicone is soft and elastic; the external charging electrode can push against the silicone, causing it to deform and open the opening 133. This allows the external charging electrode to extend into the mating groove 111 through the interface 112 and the opening 133, making electrical contact with the first electrode 12 to charge the body 14. Furthermore, the silicone covers the outer periphery of the external charging electrode, preventing external moisture from splashing onto the first electrode 12 during charging and causing electrochemical corrosion. This further protects the first electrode 12, preventing damage and extending its service life. After charging is complete, the external charging electrode retracts from the interface 112 and the opening 133, and the silicone returns to its original position, closing the opening 133.

[0045] like Figure 5 As shown, both the first stop 131 and the second stop 132 include an inclined surface 134 facing the first electrode 12. From the opening 133 to both sides of the inner wall of the docking groove 111, the inclined surface 134 slopes towards the side away from the first electrode 12. The inclined surface 134 allows the first stop 131 and the second stop 132 to have a larger deformation space, improving their deformation capability. This ensures that after the external charging electrode exits the docking interface 112 and the opening 133, the first stop 131 and the second stop 132 can promptly reset and close the opening 133, thereby extending the service life of the stop 13.

[0046] like Figures 4 to 5 As shown, the stop 13 also includes a fixing part 135, which is a cylindrical structure with both ends connected. The outer peripheries of the first stop 131 and the second stop 132 are connected to the inner wall of the fixing part 135, and the first stop 131, the second stop 132 and the fixing part 135 can be integrally formed. The stop 13 is embedded in the mating groove 111 by the fixing part 135 through an interference fit, so as to connect the first stop 131 and the second stop 132 with the mating part 11.

[0047] In another embodiment, both the first stop 131 and the second stop 132 are configured as baffles, which are rotatably disposed on the inner wall of the docking groove 111. The stop 13 also includes a reset member (not shown) disposed between the baffle and the inner wall of the docking groove 111. When the opening 133 is opened, the reset member deforms. The external charging electrode can push against the baffle, causing the baffle to rotate relative to the docking member 11 toward the first electrode member 12 and open the opening 133. The reset member deforms, allowing the external charging electrode to extend into the docking groove 111 through the interface 112 and the opening 133 and make electrical contact with the first electrode member 12 to charge the body 14. After charging is completed, the external charging electrode withdraws from the interface 112 and the opening 133, and the baffle can rotate in the opposite direction to reset and close the opening 133 under the action of the reset member. The baffle can be rotatably connected to the inner wall of the docking groove 111 via a rotating shaft (not shown). The reset component can be a torsion spring sleeved on the rotating shaft. The two torsion arms of the torsion spring are respectively connected to the baffle and the inner wall of the docking groove 111. When the baffle rotates relative to the docking component 11 toward the first electrode component 12 and opens the opening 133, the torsion spring is twisted. Alternatively, the reset component can also be a spring, a spring sheet, a silicone rubber component, or other elastic element. The two ends of the reset component are respectively connected to the baffle and the inner wall of the docking groove 111. When the baffle rotates relative to the docking component 11 toward the first electrode component 12 and opens the opening 133, the reset component is compressed.

[0048] Furthermore, the charging assembly also includes an elastic element (not shown), which is disposed on the side of the first electrode 12 away from the interface 112. When the external charging electrode makes electrical contact with the first electrode 12, it can apply pressure to the first electrode 12, causing the elastic element to be compressed and applying an elastic force towards the external charging electrode to the first electrode 12. This ensures stable and reliable electrical contact between the external charging electrode and the first electrode 12, preventing poor contact that could lead to charging failure. The elastic element can be a spring, sheet, silicone rubber, or other elastic components. Both ends of the elastic element are connected to the inner wall of the first electrode 12 and the docking groove 111 away from the interface 112, respectively. Alternatively, both ends of the elastic element can be connected to the first electrode 12 and the body 14, respectively. Of course, the first electrode 12 can also be fixedly disposed on the inner wall of the docking groove 111 away from the interface 112.

[0049] like Figure 1 and Figure 6As shown, this embodiment of the present invention also provides a cleaning robot, including a base station 20 and a host 10, wherein: the base station 20 includes a base 21 and a second electrode 22, the second electrode 22 being disposed on the base 21 and electrically connected to the base 21; the host 10 includes a body 14 and the aforementioned charging assembly, when the body 14 is engaged with the base 21, the second electrode 22 is in electrical contact with the first electrode 12. When the body 14 of the cleaning robot needs to be charged, the body 14 is controlled to move to a position engaged with the base 21, and simultaneously the stop 13 is controlled to open the interface 112, exposing the first electrode 12, and the second electrode 22 is in electrical contact with the first electrode 12 to charge the body 14.

[0050] like Figure 1 and Figure 6 As shown, the base station 20 also includes a base station recharge lamp 24 disposed on the base 21 for transmitting a recharge signal, and the host 10 also includes a host recharge lamp 15 disposed on the body 14 for receiving the recharge signal transmitted by the base station recharge lamp 24, so that the body 14 can move to a position that cooperates with the base 21 according to the recharge signal, so as to facilitate the positioning of the body 14 and the base 21.

[0051] like Figures 6 to 7 As shown, the base station 20 also includes a positioning member 23 protruding from the base 21, and a second electrode member 22 disposed at the end of the positioning member 23 away from the base 21. When the body 14 mates with the base 21, the positioning member 23 is inserted into the docking groove 111 through the interface 112, so that the second electrode member 22 makes electrical contact with the first electrode member 12. When the body 14 of the cleaning robot needs to be charged, the body 14 is controlled to move to a position that mates with the base 21, so that the positioning member 23 extends into the docking groove 111 through the interface 112 and the opening 133, and the second electrode member 22 makes electrical contact with the first electrode member 12 to charge the body 14. By setting the second electrode member 22 on the positioning member 23, it is not necessary to open an additional positioning groove on the body 14, and it is also easier to assemble the second electrode member 22, thereby improving the overall appearance of the body 14 and the base 21 and saving on component costs. When the base 21 recognizes the charging signal, it can be determined that the body 14 and the base 21 are successfully aligned. During the charging process, the first electrode 12 and the second electrode 22 are both located in the docking groove 111. When the first stop 131 and the second stop 132 are made of silicone, the silicone can also cover the outer periphery of the positioning member 23, thereby preventing external moisture from splashing onto the first electrode 12 and the second electrode 22 and causing electrochemical corrosion, protecting the first electrode 12 and the second electrode 22, preventing damage to the first electrode 12 and the second electrode 22, and extending the service life of the first electrode 12 and the second electrode 22.

[0052] like Figure 2 and Figure 7As shown, in one embodiment, the inner wall of the mating groove 111 is provided with a first guide surface 113, which gradually slopes outward from the first electrode 12 to the mating interface 112. That is, the inner diameter of the mating groove 111 gradually increases from the first electrode 12 to the mating interface 112. The outer wall of the positioning member 23 is provided with a second guide surface 231, which gradually slopes inward from the base 21 to the second electrode 22. That is, the outer diameter of the positioning member 23 gradually decreases from the base 21 to the second electrode 22. Thus, even if the positioning member 23 is not completely aligned with the mating groove 111, the first guide surface 113 and the second guide surface 231 can guide the positioning member 23, allowing it to move to a position completely aligned with the mating groove 111 and insert into the mating groove 111, thereby further facilitating the positioning of the body 14 and the base 21. Of course, in other embodiments, the first guide surface 113 may be provided only on the inner wall of the docking groove 111, or the second guide surface 231 may be provided only on the outer wall of the positioning member 23.

[0053] like Figure 2 and Figure 7 As shown, in one embodiment, there are two charging components arranged at an interval, and two positioning elements 23 and two second electrode elements 22, each corresponding to one of the charging components. By having the two positioning elements 23 engage with the two docking slots 111 for positioning, the stability and reliability of the docking between the body 14 and the base 21 can be improved. Alternatively, in other embodiments, the first positioning element 23 may engage with one docking slot 111 for positioning, with the two first electrode elements 12 shared within one docking slot 111, and the two second electrode elements 22 shared at the end of the positioning element 23 furthest from the base 21.

[0054] like Figure 1 and Figure 7As shown, the main body 14 is equipped with a water storage tank (not shown) and a water inlet 141 connected to the water storage tank. The base 21 is equipped with a water outlet 211. When the positioning member 23 is inserted into the docking groove 111 through the interface 112, the water outlet 211 aligns with the water inlet 141. The insertion of the positioning member 23 into the docking groove 111 causes the second electrode member 22 to make electrical contact with the first electrode member 12, and simultaneously the water outlet 211 aligns with the water inlet 141. This allows for simultaneous charging of the main body 14 and replenishment of the water storage tank within the main body 14, eliminating the need for manual replenishment by the user and thus improving the working efficiency and automation level of the cleaning robot. The base 21 may contain a water storage tank connected to the water outlet 211, allowing the user to replenish the tank periodically or as needed. Alternatively, the water outlet 211 may be directly connected to an external water source. When there are two positioning elements 23, the two positioning elements 23 can be set on both sides of the water outlet 211. The positioning components and the water inlet 141 are respectively arranged in correspondence with the positioning elements 23 and the water outlet 211 to ensure that the host 10 and the base station 20 have a neat appearance.

[0055] like Figure 1 and Figure 6 As shown, the main body 14 is equipped with a dust collection box (not shown) and a dust discharge port (not shown) connected to the dust collection box. The base 21 is equipped with a dust collection port 212. When the positioning member 23 is inserted into the docking groove 111 through the interface 112, the dust collection port 212 is connected to the dust discharge port. When the positioning member 23 is inserted into the docking groove 111, the second electrode member 22 makes electrical contact with the first electrode member 12, and the dust collection port 212 is also connected to the dust discharge port. This allows the dust collection box inside the main body 14 to be cleaned while the main body 14 is being charged, eliminating the need for manual cleaning of the dust collection box by the user. This improves the working efficiency and automation of the cleaning robot. The base 21 may be equipped with a dust collection box connected to the dust collection port 212. The user can clean the dust collection box periodically or when needed. Alternatively, the dust collection port 212 may be directly connected to an external trash can.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
