Description

Technical Field

[0001] This application relates to the field of robotic vacuum cleaners, and more particularly to a locking structure. Background Technology

[0002] With the development of smart homes, robotic vacuum cleaners have been widely used in household cleaning. The roller, a key component of these cleaners, is responsible for sweeping floors and collecting dust. However, traditional robotic vacuum cleaner rollers are often fixed inside the machine, requiring users to use tools to disassemble them for cleaning or replacement. This complicates the process, increases maintenance difficulty, and reduces the user experience.

[0003] To address the inconvenience of disassembling traditional rollers, existing technologies have proposed several locking structures that facilitate disassembly. For example, some solutions employ a snap-on structure, allowing for quick roller disassembly by pressing the snap-on mechanism; others use a magnetic structure to secure the roller, making it easy for users to remove it. These solutions simplify the roller disassembly process and improve maintenance efficiency to some extent.

[0004] However, existing locking structures still have some shortcomings. For example, while snap-on structures are easy to operate, the pressing elements are prone to wear during frequent disassembly, leading to malfunctions or disconnection. Magnetic structures may affect the fixing effect of the roller due to insufficient magnetic force or unstable adsorption. In addition, these solutions often lack stability in the locked state, causing the roller to loosen or fall off during operation. Therefore, there is still a need for a roller locking structure for robotic vacuum cleaners that is easy to disassemble. Utility Model Content

[0005] In view of this, it is necessary to provide a locking structure that is easy to disassemble in order to solve the above problems.

The locking structure further includes:

[0007] The rotating component includes a connecting part, a pushing part, and a torsion ring arranged in sequence, wherein the connecting part is flipped onto the cleaning drum;

[0008] A locking assembly includes a latch and an elastic element. The latch has a receiving hole, and the elastic element is disposed in the receiving hole. One end of the elastic element abuts against the inner wall of the receiving hole, and the other end abuts against the housing.

[0009] The pushing part has a pushing surface facing the latch, the latch can abut against the pushing surface, and along the flipping direction of the pushing part, the minimum distance between the pushing surface and the latch gradually increases or decreases.

[0036] The following is in conjunction with the appendix Figure 1-7 The present application provides a detailed description of some embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] This application provides a locking structure 100 disposed on the cleaning roller 1 of a sweeping robot. The sweeping robot has a locking hole 2. The sweeping robot includes a housing 3 and the locking structure 100 disposed on the housing 3. The locking structure 100 can be locked into the locking hole 2. The locking structure 100 further includes:

[0038] The rotating component 5 includes a connecting part 6, a pushing part 7, and a torsion ring 8 arranged in sequence, wherein the connecting part 6 is flipped onto the cleaning drum 1;

[0039] The locking assembly 9 includes a latch 10 and an elastic element 11. The latch 10 has a receiving hole 12. The elastic element 11 is disposed in the receiving hole 12, and one end of the elastic element 11 abuts against the inner wall of the receiving hole 12, and the other end abuts against the housing 3.

[0040] The pushing part 7 has a pushing surface 13 facing the latch 10, the latch 10 can abut against the pushing surface 13, and along the flipping direction of the pushing part 7, the minimum distance between the pushing surface 13 and the latch 10 gradually increases or decreases.

[0041] Specifically, a locking structure 100 is installed on the cleaning roller 1 of a sweeping robot and can be locked into the locking hole 2 on the robot housing 3. The main features of the structure are that it includes a rotating member 5 and a locking assembly 9. The rotating member 5 consists of a connecting part 6, a pushing part 7 and a torsion ring 8. The connecting part 6 can be flipped and installed on the cleaning roller 1. The locking assembly 9 includes a latch 10 and an elastic member 11. The latch 10 has a receiving hole 12. One end of the elastic member 11 abuts against the inner wall of the receiving hole 12 and the other end abuts against the housing 3. The pushing surface 13 on the pushing part 7 contacts the latch 10. The pushing surface 13 gradually changes the minimum distance along the flipping direction, thereby adjusting the locking or unlocking state of the latch 10. This design can change the locking state by rotating the pushing part, ensuring that the cleaning roller 1 is firmly fixed inside the sweeping robot during use. It is suitable for use when loading, unloading or maintaining the roller during cleaning. Its operation process is as follows: external force is applied through the torsion ring 8, causing the pushing part 7 to push the latch 10, changing the contact state between the latch 10 and the pushing surface 13, and finally achieving locking or unlocking. The application scenario is that when the robot vacuum needs to clean the roller 1 regularly or replace parts, the user can easily operate this locking structure 100.

[0042] In a specific example, the locking structure 100 includes a first locking component 14 and a second locking component 15, which are respectively disposed at both ends of the rotating member 5, and both the first locking component 14 and the second locking component 15 correspond to the card hole 2.

[0043] Specifically, the first locking component 14 and the second locking component 15 are respectively located at both ends of the rotating part 5 and correspond to the locking hole 2. This design helps to improve the stability of the locking structure 100 and prevent the cleaning roller 1 from loosening or shifting due to uneven force during operation. The two locking components 9 work together to lock the cleaning roller 1 more effectively, thereby enhancing the robustness and durability of the entire device.

[0044] In one specific example, the cleaning roller 1 includes a locking structure housing 16, which is located at one end of the cleaning roller 1, and the rotating member 5 and the locking assembly 9 are both located inside the locking structure housing 16.

[0045] Specifically, the housing 3 is located at one end of the cleaning drum 1, and the rotating part 5 and the locking assembly 9 are both installed inside the housing 3. This design can protect the internal components of the locking structure 100 from the influence of the external environment, such as dust and moisture, and improve the durability and service life of the locking structure 100. The housing 3 can also provide additional support for the cleaning drum 1, further increasing the stability and safety of the entire device.

[0046] In one specific example, a fixing block 17 is provided in the receiving hole 12, and the elastic element 11 is sleeved on the fixing block 17.

[0047] Specifically, the elastic element 11 is sleeved on the fixed block 17. Through this structural design, the elastic element 11 can better maintain its original position and avoid displacement or loosening during use. At the same time, the presence of the fixed block 17 can also enhance the compression performance of the elastic element 11, thereby improving the locking effect and reliability of the locking structure 100 and ensuring that the cleaning roller 1 can still operate stably under high-intensity working environment.

[0048] In one specific example, the housing 3 has a rotating groove 18, the connecting part 6 is located in the rotating groove 18, and the connecting part 6 is able to rotate in the rotating groove 18.

[0049] Specifically, by providing a rotating groove 18 inside the housing 3, the connecting part 6 can rotate freely within the rotating groove 18. This design helps to improve the flexibility of the locking structure 100, making it more convenient to install or disassemble the cleaning roller 1. At the same time, the presence of the rotating groove 18 also limits the rotation range of the connecting part 6, ensuring that the locking structure remains stable in the working state.

[0050] In one specific example, the housing 3 has a through hole 19, and the torsion ring 8 extends out of the through hole 19. When the pushing surface 13 reaches the minimum distance from the latch 10, the torsion ring 8 abuts against the locking structure housing 16.

[0051] Specifically, the torsion ring 8 can extend out of the through hole 19 and abut against the locking structure housing 16 when the pushing surface 13 reaches its minimum distance. This design allows the user to judge the locking state of the locking structure 100 by observing the position of the torsion ring 8, avoiding operational errors. At the same time, the through hole 19 also provides more room for the torsion ring 8 to move, further improving the ease of operation of the locking structure 100.

[0052] In one specific example, the locking structure includes a fixing member 21, one end of which is fixedly connected to the housing 3, and the other end is locked to the cleaning roller 1.

[0053] Specifically, one end of the fixing member 21 is fixedly connected to the housing 3, and the other end is locked to the cleaning roller 1. This design can provide additional fixed support for the cleaning roller 1, ensuring that it will not shift or loosen due to vibration or external force during operation. The presence of the fixing member 21 makes the locking structure 100 more robust and reliable, which is especially suitable for sweeping robots that need to work for a long time.

[0054] In one specific example, the housing 3 has a movable groove 22, the locking assembly 9 is disposed in the movable groove 22 and slidably connected to the movable groove 22, and one end of the elastic member 11 abuts against the inner wall of the movable groove 22.

[0055] Specifically, the locking component 9 is located in and slidably connected to the movable groove 22, and one end of the elastic element 11 abuts against the inner wall of the movable groove 22. Through this design, the locking component 9 can slide and adjust within a certain range to adapt to cleaning rollers 1 of different sizes or shapes, further improving the compatibility and applicability of the locking structure 100. At the same time, the design of the movable groove 22 also enhances the flexibility and ease of operation of the locking component 9.

[0056] In one specific example, a fixing member 21 is provided on the contact end between the locking structure housing 16 and the cleaning roller 1. One end of the fixing member 21 is fixedly connected to the locking structure housing 16, and the other end is locked to the cleaning roller 1.

[0057] Specifically, the fixing member 21 is a circular cap-shaped structure used to connect the locking structure housing 16 and the cleaning roller 1. This design not only provides additional support for the cleaning roller 1, but also enhances the overall stability and safety of the locking structure 100 through the presence of the fixing member 21, avoiding loosening or displacement problems during long-term use.

[0058] In one specific example, it includes the housing 3 and the locking structure 100.

[0059] Specifically, all the aforementioned designs propose applying these locking structures to the robot vacuum cleaner. This design can significantly improve the overall performance and user experience of the robot vacuum cleaner, especially during the installation and removal of the cleaning roller 1. Users can complete the operation more conveniently and quickly, ensuring the secure installation of the cleaning roller 1 and avoiding safety hazards caused by improper operation.

[0060] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
