Abstract
Description
Technical Field
[0001] This application relates to the field of household appliance technology, and in particular to an alignment component and a sweeping robot. Background Technology
[0002] In related technologies, there is a type of sweeping robot whose main unit has a water tank. When the water in the tank is insufficient, the main unit needs to automatically return to the base station to replenish the water. Before replenishing the water tank, the main unit needs to align with the base station. After alignment, the water tank is replenished.
[0003] However, in related technologies, the main unit of most sweeping machines is disc-shaped. The positioning accuracy of disc-shaped main units is relatively low. Therefore, water leakage is likely to occur during the process of replenishing the water tank. Utility Model Content
[0004] In view of this, embodiments of this application aim to provide an alignment component and a sweeping machine that can improve the alignment accuracy between the host and the base station.
[0005] To achieve the above objectives, one embodiment of this application provides an alignment component for alignment between the base station and the host of a robotic vacuum cleaner. The alignment component includes:
[0006] A mounting base disposed on the main body of the base station;
[0007] A trigger element slidably connected to the mounting base, the trigger element protruding from the body, to slide along the mounting base under the push of the host unit upon entering the station;
[0008] The detection unit is installed on the main body, and the detection unit detects the inbound accuracy of the host by detecting the position of the trigger;
[0009] An elastic reset element provides a force opposite to the force exerted by the host on the trigger element when the host enters the base station, so as to reset the trigger element after the host leaves the base station.
[0010] In one embodiment, the trigger has a detection part, and the detection unit is disposed at a preset position on the sliding trajectory of the trigger. When the trigger slides to the preset position, the detection unit detects that the host has entered the station.
[0011] In one embodiment, the detection unit is a photoelectric detection unit, which includes a transmitting unit and a receiving unit, and the detected part includes a light-shielding plate.
[0012] In one embodiment, the trigger has a connector that plugs into the incoming host.
[0013] In one embodiment, the trigger has a slide bar, the mounting base has a mounting hole, and the slide bar is slidably inserted into the mounting hole.
[0014] In one embodiment, the alignment component includes a limiting member disposed on the slide rod and located outside the mounting hole. When the trigger is in the initial position, the limiting member abuts against the portion of the mounting base located around the mounting hole.
[0015] In one embodiment, the trigger has a guide ring, the mounting base has a ring sleeve, one of the ring sleeve and the guide ring has an annular groove extending along the sliding direction of the trigger, and the other of the ring sleeve and the guide ring slidably extends into the annular groove; and / or,
[0016] The trigger has a first guide portion, the mounting base has a second guide portion, one of the first guide portion and the second guide portion has a guide groove extending along the sliding direction of the trigger portion, and the other of the first guide portion and the second guide portion slidably extends into the guide groove.
[0017] In one embodiment, the base station includes a water injection pipe, the host includes a water tank with a host water inlet, the trigger has a water injection channel, and the trigger, by plugging into the host, enables the water injection pipe to be in fluid communication with the water tank through the water injection channel and the host water inlet.
[0018] In one embodiment, the trigger includes a connector having the water injection channel and a sealing ring sleeved on the connector, the connector being plugged into the main unit and the sealing ring being in sealing contact with the main unit.
[0019] In one embodiment, the connector has a limiting groove, and the sealing ring is engaged in the limiting groove; and / or,
[0020] The host has an alignment hole, the trigger is inserted into the alignment hole, and the sealing ring includes sealing blades spaced apart along the sliding direction of the trigger, each of the sealing blades making sealing contact with the side wall of the alignment hole.
[0021] This application also provides a sweeping robot in one embodiment, including a base station and a host. The base station includes a body and the alignment component described above. The mounting base and the detection unit are disposed on the body, and the trigger protrudes from the body.
[0022] In one embodiment, the base station includes a charging component, and the host includes a charging electrode corresponding to the charging component. When the detection unit detects that the trigger has slid to the preset position and a conductive signal is generated between the charging component and the charging electrode, the host enters the station position.
[0023] In one embodiment, the number of alignment components is multiple, and each alignment component is arranged at a lateral interval along the body.
[0024] This application provides an alignment component and a sweeping robot. The alignment component includes a mounting base, a trigger, a detection unit, and an elastic reset component. The mounting base and detection unit are both mounted on a base station. The trigger is slidably connected to the mounting base. During alignment between the host and the base station, the host moves towards the base station, pushing the trigger along the mounting base. When the trigger reaches a set position, it triggers the detection unit, enabling the detection unit to detect the trigger's position. When the detection unit detects the trigger's position, it indicates that the host has entered the correct position. Simultaneously, as the trigger slides along the mounting base, the elastic reset component accumulates elastic potential energy under continuous force. After the host leaves the base station, the host separates from the base station, and the elastic reset component releases the accumulated elastic potential energy, causing the trigger to return to its initial position. The triggered detection unit also returns to its initial state before triggering. Since the detection unit can detect the host's entry accuracy by detecting the position of the trigger, the alignment component of this application can improve the accuracy of host-base station alignment.

Figure 7 The orientation or positional relationship shown, with "horizontal" indicating the orientation or positional relationship based on the attached... Figure 2 The orientations or positional relationships shown are for the convenience of describing the embodiments of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.
[0037] This application provides a sweeping robot; please refer to [link / reference]. Figures 1 to 6 The sweeper includes a base station 10 and a main unit 20. The main unit 20 is used to perform cleaning work on the ground. The main unit 20 can automatically return to the base station by connecting to the base station 10 via a signal. After the main unit 20 returns to the base station, the base station 10 can charge the main unit 20 and replenish the water tank 22 (the main unit 20 without a water tank 22 can only be charged).
[0038] Base station 10 includes a body 13 and an alignment component 11 as described in any embodiment of this application. The alignment component 11 is used for alignment between base station 10 and host 20. The alignment component 11 includes a mounting base 112, a trigger 111, a detection unit 12, and an elastic reset component 114. The mounting base 112 and the detection unit 12 are both disposed on the body 13. The trigger 111 is slidably connected to the mounting base 112. The trigger 111 protrudes from the body 13 so as to slide along the mounting base 112 under the push of the host 20 entering the station. The detection unit 12 detects the entry accuracy of the host 20 by detecting the position of the trigger 111. The elastic reset component 114 provides a force opposite to the force of the host 20 pushing the trigger 111 when the host 20 enters the station so as to reset the trigger 111 after the host 20 leaves the base station 10.
[0039] Figure 7 The elastic reset element 114 shown is a spring. In some other embodiments, the elastic reset element 114 may also be an element that can produce elastic deformation, such as elastic silicone. No further limitations are made here.
[0040] During the alignment process between the host 20 and the base station 10, the host 20 moves towards the base station 10, pushing the trigger 111 to slide along the mounting base 112. When the trigger 111 slides to a set position, it triggers the detection unit 12, enabling the detection unit 12 to detect the position of the trigger 111. When the detection unit 12 detects the position of the trigger 111, it indicates that the host 20 has entered the site. Simultaneously, as the trigger 111 slides along the mounting base 112, the elastic reset member 114 continuously accumulates elastic potential energy under pressure. After the host 20 leaves the site, it separates from the base station 10, and the elastic reset member 114 releases the accumulated elastic potential energy, causing the trigger 111 to return to its initial position. The triggered detection unit 12 also returns to its initial state before triggering. Since the detection unit 12 can detect the entry accuracy of the host 20 by detecting the position of the trigger 111, the alignment component 11 of this embodiment can improve the alignment accuracy between the host 20 and the base station 10.
[0041] It should be noted that the alignment component 11 in this application embodiment can be used for alignment between the host 20 and the base station 10 before the water tank 22 is replenished with water, and can also be used for alignment between the host 20 and the base station 10 before the host 20 is charged.
[0042] In one embodiment, please refer to Figure 3 The base station 10 has multiple alignment components 11. The multiple alignment components 11 work together to detect the alignment between the host 20 and the base station 10. When a single alignment component 11 fails, it does not have a significant impact on the detection results, thereby effectively reducing detection errors and thus effectively reducing water leakage and electrical leakage caused by misalignment.
[0043] Figure 3 The base station 10 shown is provided with two alignment components 11, and the host 20 is provided with two alignment holes 21a. In some other embodiments, the number of alignment components 11 and alignment holes 21a may be more than two. For example, the number of alignment components 11 and alignment holes 21a may be three or four.
[0044] Please see Figure 2 and Figure 8 To further reduce alignment angle deviation, each alignment component 11 can be arranged at a lateral interval along the body 13 to perform double or multiple alignment of the host 20 and the base station 10 in the lateral direction, thereby effectively reducing alignment angle deviation. In other embodiments, any two alignment components 11 can also be arranged at a vertical or diagonal interval.
[0045] In one embodiment, please refer to Figure 3 and Figure 4 The trigger 111 has a detection part 1115, and the detection unit 12 is set at a preset position on the sliding trajectory of the trigger 111. When the trigger 111 slides to the preset position, the detection unit 12 detects that the host 20 has entered the station. That is, when the host 20 pushes the trigger 111 to slide to the preset position, the detection unit 12 detects the alignment between the host 20 and the base station 10 by detecting the detection part 1115.
[0046] For example, please continue reading Figure 3 and Figure 4 The detection unit 12 can be a photoelectric detection unit, which includes a transmitting unit 121 and a receiving unit 122. The detected part includes a light shield. When the host 20 pushes the trigger 111 to a set position, the detected part 1115 on the trigger 111 moves to a specific position between the transmitting unit 121 and the receiving unit 122. The light shield can block the signal transmission path between the transmitting unit 121 and the receiving unit 122, and the detection unit 12 can be triggered accordingly by sensing the interruption of signal transmission. When the detected part 1115 on the trigger 111 is not in the specific position, normal signal transmission occurs between the transmitting unit 121 and the receiving unit 122, and the detection unit 12 will not be triggered, which also means that there is a positional deviation between the host 20 and the base station 10.
[0047] In other embodiments, the detection unit 12 may also employ other triggering methods. For example, the detection unit 12 may be a micro switch with a push rod, and the trigger member 111 triggers the corresponding micro switch by pushing the push rod. When the host 20 pushes the trigger member 111 to a set position, the trigger member 111 pushes the push rod, thereby triggering the micro switch. The detection unit 12 may also be a Hall element, and the detected part 1115 is a metal component. When the detected part 1115 moves to the set position, the detected part 1115 generates a Hall effect under the action of a magnetic field, so that the Hall element detects the detected part 1115 and generates a trigger signal.
[0048] In one embodiment, please refer to Figure 1 , Figure 7 and Figure 8 The trigger 111 has a connector 1111, which is plugged into the host 20 entering the station. The host 20 moves towards the base station 10 to engage with the connector 1111. After the engagement is completed, the host 20 continues to move and exerts a force on the trigger 111. Driven by the force, the trigger 111, which is slidably connected to the mounting base 112, can slide.
[0049] In one embodiment, please refer to Figure 7 The trigger 111 has a slide rod 1112, and the mounting base 112 has a mounting hole 112a. The slide rod 1112 can slide through the mounting hole 112a. That is, the trigger 111 and the mounting base 112 are slidably connected through the slide rod 1112 and the mounting hole 112a. The slide rod 1112 can guide the sliding of the trigger 111. Under the guidance of the slide rod 1112, the trigger 111 will move along a predetermined direction and trajectory. After the trigger 111 is inserted and engaged with the host 20, the host 20 will stably push the trigger 111 to the trigger position of the detection unit 12, effectively preventing the detection unit 12 from making a judgment error.
[0050] Please see Figure 6 and Figure 7 The alignment component 11 may include a limiting member 113, which is disposed on the slide rod 1112 and located outside the mounting hole 112a. When the trigger member 111 is in the initial position, the limiting member 113 abuts against the part of the mounting base 112 located on the periphery of the mounting hole 112a, so as to better prevent the slide rod 1112 from coming out of the mounting hole 112a.
[0051] Please see Figure 6 and Figure 7The elastic reset member 114 can be sleeved on the outside of the slide bar 1112 and abuts against the mounting base 112 and the trigger member 111 respectively. After the trigger member 111 is inserted into the corresponding alignment hole 21a, the elastic reset member 114 undergoes elastic deformation under the force applied by the host 20 as the host 20 continues to push the trigger member 111. After the host 20 is separated from the base station 10, the host 20 no longer applies force to the elastic reset member 114, and the elastic reset member 114 returns to its original shape under its own elastic force, thereby driving the trigger member 111 back to its initial position.
[0052] In one embodiment, please refer to Figure 6 and Figure 7 The trigger 111 has a guide ring 1113, and the mounting base 112 has a ring sleeve 1121. One of the ring sleeve 1121 and the guide ring 1113 has an annular groove 1121a extending along the sliding direction of the trigger 111, and the other of the ring sleeve 1121 and the guide ring 1113 slidably extends into the annular groove 1121a. That is, the ring sleeve 1121 of the mounting base 112 may have an annular groove 1121a, and during the process of the host 20 pushing the trigger 111, the trigger 111 slides along the annular groove 1121a, thereby improving the stability of the trigger 111 during movement. Alternatively, the guide ring 1113 of the trigger 111 may have an annular groove 1121a, and during the process of the host 20 pushing the trigger 111, the trigger 111 slides along the ring sleeve 1121 of the mounting base 112, thereby improving the stability of the trigger 111 during movement.
[0053] In one embodiment, please refer to Figure 6 The trigger 111 has a first guide portion 1114, and the mounting base 112 has a second guide portion 1122. One of the first guide portion 1114 and the second guide portion 1122 has a guide groove 1122a extending along the sliding direction of the trigger 111, and the other of the first guide portion 1114 and the second guide portion 1122 extends into the guide groove 1122a. That is, the trigger 111 may have a guide groove 1122a, and the trigger 111 slides along the mounting base 112 during the process of the host 20 pushing the trigger 111, thereby improving the stability of the trigger 111 during the movement; or the mounting base 112 may have a guide groove 1122a, and the trigger 111 slides along the guide groove 1122a during the process of the host 20 pushing the trigger 111, thereby also improving the stability of the trigger 111 during the movement.
[0054] In other embodiments, the trigger 111 may have both a first guide portion 1114 and a guide ring 1113, and the mounting base 112 may have both a second guide portion 1122 and a ring sleeve 1121, thereby forming a dual limiting and guiding function for the trigger 111 to reduce swaying during the movement of the trigger 111.
[0055] In one embodiment, please refer to Figures 3 to 6 The base station 10 includes a water injection pipe 14, the host 20 includes a water tank 22 with a host water inlet 22a, and the trigger 111 has a water injection channel 111a. The trigger 111 is connected to the host 20 to make the water injection pipe 14 fluidly connected to the water tank 22 through the water injection channel 111a and the host water inlet 22a.
[0056] For example, the base station 10 also includes a drain valve 15 disposed on the water inlet pipe 14. The drain valve 15 and the detection unit 12 are both signal-connected to the controller of the base station 10. The host 20 includes a housing 21 with an alignment hole 21a, and a water tank 22 is disposed inside the housing 21. The controller of the base station 10 controls the drain valve 15 to open the water inlet pipe 14 at least according to the trigger signal of the detection unit 12. That is to say, the water inlet pipe 14 in the base station 10 is used to replenish water to the host 20. Water can only flow through the water inlet pipe 14 after it is opened. Before replenishing water, it is necessary to confirm whether the base station 10 and the host 20 are aligned by the trigger signal of the detection unit 12 to effectively prevent water leakage. Specifically, when all detection units 12 are triggered, it is considered that the host 20 and the base station 10 have completed alignment. If any one or more detection units 12 are not triggered, it is considered that the host 20 and the base station 10 have not completed alignment. The controller of the base station 10 only controls the water discharge valve 15 to open the water injection pipe 14 when the host 20 and the base station 10 have completed alignment.
[0057] In one embodiment, the main unit water inlet 22a can be in fluid communication with the alignment hole 21a, and the trigger 111 has a water injection channel 111a in fluid communication with the water injection pipe 14. The trigger 111 with the water injection channel 111a is inserted into the main unit water inlet 22a through the corresponding alignment hole 21a. That is, by providing the water injection channel 111a in the trigger 111, the water injection pipe 14 and the main unit water inlet 22a can be fluidly connected by the water injection channel 111a while the trigger 111 is inserted into the alignment hole 21a.
[0058] Please see Figures 3 to 6 In the case where the base station 10 has multiple alignment components 11, the host 20 is provided with multiple alignment holes 21a, the host water inlet 22a can be in fluid communication with one of the alignment holes 21a, and at least one of the alignment components 11's triggers 111 has a water injection channel 111a in fluid communication with the water injection pipe 14.
[0059] In one embodiment, please refer to Figure 6 and Figure 7The trigger 111 includes a plug 1111 with a water injection channel 111a and a sealing ring 1116 sleeved on the plug 1111. When the plug 1111 is plugged into the main unit 20, the sealing ring 1116 is in sealed contact with the main unit 20 to ensure the connection between the trigger 111 and the main unit 20 during the water replenishment process of the main unit 20 and reduce the occurrence of water leakage.
[0060] In addition, please see Figure 7 The connector 1111 may also have a limiting groove 1111a, into which the sealing ring 1116 is inserted. The limiting effect of the limiting groove 1111a on the sealing ring 1116 can effectively improve the connection stability between the connector 1111 and the sealing ring 1116, so as to effectively prevent the sealing ring 1116 from shifting during the process of the connector 1111 being inserted into the alignment hole 21a, thus giving the sealing ring 1116 a good sealing effect.
[0061] Please continue reading. Figure 9 To further improve the sealing effect of the sealing ring 1116, the sealing ring 1116 may also include sealing blades 11161 spaced apart along the sliding direction of the trigger 111. Each sealing blade 11161 is in sealing contact with the side wall of the alignment hole 21a to form a multiple seal at the connection between the host 20 and the trigger 111.
[0062] In other embodiments, the water injection channel 111a may not be provided on the trigger 111; it is sufficient that the water injection pipe 14 can be fluidly connected to the host water inlet 22a when the base station 10 and the host 20 are aligned.
[0063] In one embodiment, the host 20 also includes a one-way valve (not shown in the figure), which is located at the host water inlet 22a to allow water to flow from the water injection channel 111a to the water tank 22. However, the one-way valve only allows water to flow from the water injection channel 111a to the water tank 22, and does not allow water in the water tank 22 to flow out from the host water inlet 22a. After the host 20 leaves the base station 10, the one-way valve is used to prevent water from leaking from the water tank 22 at the host water inlet 22a.
[0064] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 8 The base station 10 includes a charging component 16, and the host 20 includes a charging electrode 24 corresponding to the charging component 16. When all detection units 12 are triggered and the charging component 16 and the charging electrode 24 are in conductive contact, the drain valve 15 can be controlled to open the water injection pipe 14.
[0065] After the base station 10 and the host 20 are aligned, the host 20 can be charged through the contact between the charging component 16 and the charging electrode 24. Furthermore, the contact between the charging component 16 and the charging electrode 24 releases a charging signal, so the alignment between the host 20 and the base station 10 can be determined by whether a charging signal is received.
