[0051] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0052] Example 1

[0053] Please refer to Figures 1-7This embodiment provides a quick-release mechanism, including a drive shaft 10. The drive shaft 10 is used to be mounted on a maintenance module and is driven by a drive mechanism 50 of the maintenance module to rotate the drive shaft 10. One end of the drive shaft 10 has a mounting slot 11. At least one end of the mounting slot 11 is open along its extension direction. In this embodiment, the drive shaft 10 is vertically arranged in use, and the mounting slot 11 is located at the bottom end of the drive shaft 10.

[0054] It also includes a mounting shaft 20 and a limiting sleeve 30. In this embodiment, the mounting shaft 20 is used to mount the brush disc 60. In other embodiments, in addition to mounting the brush disc 60, the mounting shaft 20 can also mount other products that require quick release, which will not be described in detail. One end of the mounting shaft 20 has a mounting block 21 that is adapted to the shape of the mounting slot 11. The mounting block 21 slides into the mounting slot 11 from the open end so that the drive shaft 10 and the mounting shaft 20 are engaged axially. After being engaged, the drive shaft 10 and the mounting shaft 20 will not detach from each other axially. In this embodiment, the mounting shaft 20 is placed vertically and coaxially with the drive shaft 10 during installation. The rotating drive shaft 10 can drive the mounting shaft 20 to rotate the brush disc 60.

[0055] The limiting sleeve 30 is slidably sleeved on the outer wall of the drive shaft 10 along the axial direction of the drive shaft 10. The limiting sleeve 30 has at least a first position and a second position along its sliding direction. In the first position, the limiting sleeve 30 covers the open end. In the second position, the limiting sleeve 30 moves away from the mounting slot 11 to expose the open end. The first position is the use state of the quick-release mechanism, meaning the limiting sleeve 30 needs to ensure that the drive shaft 10 and the mounting shaft 20 do not disengage. The second position is the disassembly state of the quick-release mechanism, meaning the mounting shaft 20 needs to be removed from or installed on the drive shaft 10.

[0056] In the specific implementation process, when the mounting shaft 20 is installed and in use, the limiting sleeve 30 is in the first position, which can be referred to. Figure 1 , Figure 3 , Figure 7 As shown in Figure a, the limiting sleeve 30 is fitted outside the opening end of the mounting slot 11 along its extension direction. The limiting sleeve 30 blocks the opening end, which can prevent the mounting block 21 of the mounting shaft 20 from falling out of the mounting slot 11 during use, thereby improving the stability of the installation.

[0057] When the brush plate 60 needs to be replaced, slide the limit sleeve 30 upwards to the second position, as shown in the reference. Figure 4 , Figure 7As shown in Figure b, the limiting sleeve 30 is now away from the mounting slot 11, and the open end of the mounting slot 11 along its extension direction is exposed. The user can manually move the mounting shaft 20 to allow the mounting block 21 of the mounting shaft 20 to slide out of the mounting slot 11. At this point, the mounting shaft 20 and the brush plate 60 are completely disassembled, facilitating the replacement of the brush plate 60. During replacement, align the mounting block 21 of the new mounting shaft 20 with the open end of the mounting slot 11, then move the mounting shaft 20 to allow the mounting block 21 to embed into the mounting slot 11. Finally, move the limiting sleeve 30 to the first position. The entire operation only requires simple movement of the limiting sleeve 30 and the mounting shaft 20, facilitating the replacement of the used brush plate. The disassembly and assembly steps are simple, convenient, and time-saving.

[0058] like Figures 1-4 As shown, in some embodiments, the drive shaft 10 has a limiting groove 12 on its side wall, and the extending direction of the limiting groove 12 is consistent with the sliding direction of the limiting sleeve 30; the limiting sleeve 30 has a limiting post 31, one end of which is slidably inserted into the limiting groove 12. By setting the limiting post 31 and the limiting groove 12, this invention allows the limiting post 31 to slide directionally within the limiting groove 12 when adjusting the position of the limiting sleeve 30, thus facilitating the guidance and limiting of the sliding of the limiting sleeve 30 and improving the accuracy of the sliding of the limiting sleeve 30.

[0059] like Figure 3 and Figure 7 As shown, in some embodiments, the limiting post 31 is a ball-head plunger, also called a spring plunger, which is an existing product. A positioning bead slides at its end, and a spring inside the ball-head plunger applies an outward elastic force to the positioning bead. The bottom of the limiting groove 12 is provided with two limiting recesses 13 spaced apart along the axial direction of the drive shaft 10. When the limiting sleeve 30 is in the first position, the positioning bead portion of the ball-head plunger is embedded in the limiting recess 13 near the mounting shaft 20. When the limiting sleeve 30 is in the second position, the positioning bead portion of the ball-head plunger is embedded in the limiting recess 13 away from the mounting shaft 20. Thus, when the limiting sleeve 30 is moved to the first or second position, the positioning bead portion can be embedded in the limiting recess 13, facilitating auxiliary fixation of the limiting sleeve 30 and preventing it from falling down on its own without external force. Figure 3 and Figure 7 As shown, in this embodiment, two limit posts 31 are arranged opposite to each other on both sides of the drive shaft 10.

[0060] like Figures 1-7As shown, in some embodiments, the mounting slot 11 is a T-shaped slot, with both ends of the mounting slot 11 being open along its extension direction, and the extension direction of the mounting slot 11 being perpendicular to the axial direction of the drive shaft 10. The T-shaped slot design allows the drive shaft 10 and the mounting shaft 20 to be axially engaged and fixed together after the mounting block 21 is inserted into the mounting slot 11, preventing them from separating axially. Moreover, the T-shaped slot design facilitates the insertion or sliding of the mounting block 21 into or out of the mounting slot 11, thereby facilitating the installation and removal of the mounting shaft 20.

[0061] like Figures 4-6 As shown, in some embodiments, the drive shaft 10 has a limiting pin 14 at the bottom of the limiting groove 12, and the mounting block 21 has at least one limiting groove 211 that cooperates with the limiting pin 14 on its side wall.

[0062] By setting a limiting pin 14 and a limiting groove 211, the present invention allows the mounting block 21 to be inserted into the limiting slide groove 12 after it is embedded in the limiting groove 12. The limiting pin 14 can then be inserted into the limiting groove 211, thus limiting the movement of the mounting block 21 and improving the accuracy of the mounting block 21 installation.

[0063] Example 2

[0064] Please refer to Figures 8-9 This embodiment provides a maintenance module, including the aforementioned quick-release mechanism, a mounting box 40, a drive mechanism 50, and a brush disc 60. A drive shaft 10 is rotatably mounted in the mounting box 40, with a bearing 42 between the outer wall of the drive shaft 10 and the mounting box 40 to reduce friction during rotation. The drive mechanism 50 is located in the mounting box 40 and is driven by the drive shaft 10 to rotate it. At least one brush disc 60 is mounted on the mounting shaft 20. In use, the drive mechanism 50 drives the drive shaft 10 to rotate, which in turn drives the mounting shaft 20 and the brush disc 60 to rotate together, facilitating the maintenance of the stone floor.

[0065] like Figure 3 and Figure 7 As shown, in some embodiments, a Hall sensor 41 is provided on the side of the mounting box 40 near the limiting sleeve 30. The limiting sleeve 30 is provided with a magnetic block 32 that cooperates with the Hall sensor 41. In this embodiment, the magnetic block 32 is a magnet. The Hall sensor 41 can be connected to the control system of the stone maintenance robot. This control system can use a computer or other module with signal receiving, processing, and transmitting capabilities. The Hall sensor 41 can sense the magnetic block 32 to determine whether the limiting sleeve 30 is installed correctly, thus improving safety. The specific principle is as follows:

[0066] After the mounting shaft 20 is installed, the limiting sleeve 30 is in the first position. At this time, the magnetic block 32 is far away from the Hall sensor 41, and the magnetic block 32 is outside the sensing distance range of the Hall sensor 41. The control system of the stone maintenance robot does not perform any other prompting actions.

[0067] During the disassembly and assembly of shaft 20, the limiting sleeve 30 is in the second position. After manual installation of shaft 20, there is a possibility that the limiting sleeve 30 may not be slid down to the first position, posing a safety hazard. Therefore, when the limiting sleeve 30 is in the second position, the magnetic block 32 is close to the Hall sensor 41, and the magnetic block 32 is within the sensing distance range of the Hall sensor 41. After the control system of the stone maintenance robot receives the electrical signal from the Hall sensor 41, the stone maintenance robot will issue a prompt and prohibit the stone maintenance robot from starting the maintenance process to avoid safety accidents.

[0068] like Figures 8-9 As shown, in some embodiments, the drive mechanism 50 includes a drive motor 51, a mounting shaft 52, a driven synchronous pulley 53, and a synchronous toothed belt 54. The drive motor 51 is located at the bottom of the mounting box 40, and its drive shaft is provided with a drive gear 511. The mounting shaft 52 is rotatably mounted on the mounting box 40 via bearings. The driven gear 521 and the drive synchronous pulley 522 are fixedly sleeved on the mounting shaft 52, and the driven gear 521 meshes with the drive gear 511. The driven synchronous pulley 53 is fixedly sleeved on the drive shaft 10, and the synchronous toothed belt 54 is respectively wound around the drive synchronous pulley 522 and the driven synchronous pulley 53.

[0069] When the brush disc 60 needs to rotate, the drive motor 51 can drive the mounting shaft 52 and the active synchronous pulley 522 to rotate simultaneously. Under the transmission of the synchronous toothed belt 54, the driven synchronous pulley 53 and the drive shaft 10 can be driven to rotate simultaneously, which makes it easy to drive the brush disc 60 to rotate for maintenance work.

[0070] Optionally, the quick-release mechanism in this embodiment can be configured into two sets, with the mounting shaft 52, driven gear 521, and driving synchronous pulley 522 each configured into two sets, such as... Figure 9 As shown, the two driven gears 521 can mesh with each other, and one of the driven gears 521 can mesh with the driving gear 511. In this embodiment, the driven gear 521 and the driving gear 511 can be installed inside the mounting box 40 for concealment.

[0071] Example 3

[0072] Please refer to Figures 10-11This embodiment provides a stone maintenance robot, including a shell 70 and a mounting frame 80 disposed within the shell 70, and also includes the aforementioned maintenance module, which is mounted on the mounting frame 80 via a mounting box 40. In use, the stone maintenance robot can move on the ground, thereby moving the maintenance module and performing maintenance work on the ground.

[0073] Furthermore, unless otherwise explicitly specified or limited, the terms "installation" and "connection" in this application embodiment should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.
