Abstract
Description
[Technical Field]
[0001] This application belongs to the field of cleaning robot technology, specifically relating to a bed cleaning robot. [Background Technology]
[0002] Most bed cleaning robots currently on the market use either a fixed handle or no handle at all. For bed cleaning robots with fixed handles, the handle can hinder the robot's cleaning work. When the robot is working automatically, the handle may get tangled or caught on bed sheets, duvet covers, or other bedding items, affecting the robot's normal operation. As for bed cleaning robots without handles, when manual operation, moving, or maintenance is required, the lack of a handle often makes it difficult for users to easily hold and move the device. Furthermore, in manual use scenarios, the wheels are unnecessary, and when held by hand, the protruding wheels can actually cause inconvenience, reducing the device's efficiency and user experience. [Utility Model Content]
[0003] To address the problems of existing cleaning robots with handles easily getting tangled in automatic mode and cleaning robots without handles being inconvenient to operate in manual mode, this application provides a bed cleaning robot.
[0004] This application is achieved through the following technical solution:
[0005] A bed cleaning robot includes a body, a handle assembly connected to the body, a roller assembly hinged to the body, and a release mechanism connecting the handle assembly and the roller assembly respectively. The body is provided with a wheel compartment into which the roller assembly extends. Lifting or releasing the handle assembly causes the release mechanism to restrict or release the roller assembly from extending out of the wheel compartment.
[0006] As described above, a bed cleaning robot includes a roller assembly comprising a rotating member hinged to the body on one side, a drive wheel rotatably connected to the rotating member, and elastic members connected at both ends to the rotating member and the body respectively. The elastic members drive the rotating member to rotate relative to the body, causing the drive wheel to extend out of the wheel chamber.
[0007] As described above, in a bed cleaning robot, the rotating component has a first connection position on the side near the hinge between the rotating component and the body for connecting one end of the elastic component, and the body has a second connection position on the side near the drive wheel and away from the rotating component for connecting the other end of the elastic component.
[0008] As described above, a bed cleaning robot includes a handle assembly that is hinged to the body, a first connecting rod connected to the handle, two linkage rods with one end hinged to both ends of the first connecting rod, and two second connecting rods that are hinged to the other end of each linkage rod. The linkage rods are provided with limiting protrusions, and the body is provided with limiting grooves for the limiting protrusions to slide.
[0009] As described above, in a bed cleaning robot, the release mechanism includes a release push block connected to the second link and a limiting block disposed on the rotating member. The release push block abuts against the limiting block to restrict the drive wheel from extending out of the wheel chamber.
[0010] As described above, a bed cleaning robot has a sliding groove on its body for maintaining the second link to move back and forth in the horizontal direction, and a through hole for the release push block to extend into or out of the wheel chamber.
[0011] As described above, in a bed cleaning robot, the limiting groove includes a first limiting position and a second limiting position. The limiting protrusion slides to the first limiting position, and simultaneously, the linkage drives the second connecting rod to cause the release push block to abut against the limiting block to restrict the drive wheel from extending out of the wheel chamber. The limiting protrusion slides to the second limiting position, and simultaneously, the linkage drives the second connecting rod to cause the release push block to disengage from the limiting block to release the restriction on the drive wheel extending out of the wheel chamber.
[0012] As described above, a bed cleaning robot has a guide groove on its body that abuts against the first connecting rod. The guide groove includes a first guide position corresponding to the first limit position and a second guide position corresponding to the second limit position.
[0013] As described above, in a bed cleaning robot, lifting the handle causes the first link to slide to the first guide position, and releasing the handle causes the first link to slide to the second guide position.
[0014] A bed cleaning robot as described above includes two roller assemblies respectively located on both sides of the body.
[0015] Compared with the prior art, this application has the following advantages:
[0016] This application discloses a bed cleaning robot that achieves coordinated control of handle operation and wheel extension / retraction through a mechanical linkage design between a handle assembly and a roller assembly. After applying external force to press the roller assembly into the wheel chamber, when the handle assembly is manually lifted, the release mechanism, under traction, prevents the roller assembly from extending out of the wheel chamber, thus retracting it into the robot body. At this time, the handle provides a stable grip point for manual operation, eliminating interference from exposed wheels and preventing frictional resistance between the wheels and the cleaning surface. Conversely, when the handle assembly is released... The locking mechanism releases the constraint on the roller assembly, which automatically extends out of the wheel chamber under the drive of gravity or elastic reset mechanism. This ensures that the equipment has stable movement support and obstacle-crossing ability in automatic cleaning mode. At the same time, the handle assembly falls to the body to avoid snagging and tangling with flexible items such as sheets and duvet covers. This optimizes the functional compatibility of the equipment in manual and automatic modes, solving the defect of fixed handles interfering with the cleaning process and overcoming the pain point of difficult handling of handleless equipment. It significantly improves the ease of operation, mode switching efficiency and adaptability to multiple scenarios. [Attached Image Description]

Detailed Implementation Methods
[0025] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.
[0026] Please see Figures 1 to 7 A bed cleaning robot includes a body 1, a handle assembly 2 connected to the body 1, a roller assembly 3 hinged to the body 1, and a release mechanism 4 connecting the handle assembly 2 and the roller assembly 3 respectively. The body 1 is provided with a wheel chamber 11 into which the roller assembly 3 extends. Lifting or releasing the handle assembly 2 respectively drives the release mechanism 4 to restrict or release the roller assembly 3 from extending out of the wheel chamber 11.
[0027] This application discloses a bed cleaning robot that achieves coordinated control of handle operation and wheel extension / retraction through a mechanical linkage design between a handle assembly and a roller assembly. After applying external force to press the roller assembly into the wheel chamber, when the handle assembly is manually lifted, the release mechanism, under traction, prevents the roller assembly from extending out of the wheel chamber, thus retracting it into the robot body. At this time, the handle provides a stable grip point for manual operation, eliminating interference from exposed wheels and preventing frictional resistance between the wheels and the cleaning surface. Conversely, when the handle assembly is released... The locking mechanism releases the constraint on the roller assembly, which automatically extends out of the wheel chamber under the drive of gravity or elastic reset mechanism. This ensures that the equipment has stable movement support and obstacle-crossing ability in automatic cleaning mode. At the same time, the handle assembly falls to the body to avoid snagging and tangling with flexible items such as sheets and duvet covers. This optimizes the functional compatibility of the equipment in manual and automatic modes, solving the defect of fixed handles interfering with the cleaning process and overcoming the pain point of difficult handling of handleless equipment. It significantly improves the ease of operation, mode switching efficiency and adaptability to multiple scenarios.
[0028] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the roller assembly 3 includes a rotating member 31 hinged to the body 1 on one side, a drive wheel 32 rotatably connected to the rotating member 31, and an elastic member 33 connected to the rotating member 31 and the body 1 at both ends respectively. The elastic member 33 drives the rotating member 31 to rotate relative to the body 1, causing the drive wheel 32 to extend out of the wheel chamber 11.
[0029] In this embodiment, the roller assembly 3 achieves the extension and retraction function of the drive wheel 32 through the hinge design of the rotating member 31 and the body 1, combined with the reset function of the elastic member 33. Specifically, the two ends of the elastic member 33 are connected to the rotating member 31 and the body 1 respectively. In the natural state, the elastic force of the elastic member 33 will push the rotating member 31 to rotate relative to the body 1, thereby causing the drive wheel 32 to extend out of the wheel chamber 11, ensuring that the robot has autonomous movement capability in automatic working mode. Before lifting, the drive wheel is manually pressed into the wheel chamber. When the handle assembly 2 is lifted, the release mechanism 4 will restrict the rotation of the rotating member 31, keeping the drive wheel 32 in the wheel chamber 11, avoiding friction or hooking between the wheel and the bed surface during manual operation. No additional electric drive is required, simplifying the structure and reducing energy consumption, improving the convenience and safety of manual operation. This structural design not only solves the functional disconnect between manual and automatic modes in traditional robots with fixed handles or no handles, but also enables dynamic changes in the height of the equipment chassis through the adaptive adjustment of the elastic element 33, enhancing the robot's adaptability in complex bed environments.
[0030] Furthermore, as a preferred embodiment of this solution and not a limitation, the rotating member 31 is provided with a first connection position 311 for connecting one end of the elastic member 33 near the hinge point between the rotating member 31 and the body 1, and the body 1 is provided with a second connection position 12 for connecting the other end of the elastic member 33 near the drive wheel 32 and away from the rotating member 31.
[0031] In this embodiment, the precise positioning and installation of the elastic element 33 is achieved by setting a first connecting position 311 on the rotating component 31 and a second connecting position 12 on the body 1. Specifically, the first connecting position 311 is located on the side of the rotating component 31 near its hinge point with the body 1, while the second connecting position 12 is located on the side of the body 1 near the drive wheel 32 and away from the rotating component 31. This layout ensures that the elastic element 33 can generate sufficient elastic force in its natural state to push the rotating component 31 to rotate relative to the body 1, thereby causing the drive wheel 32 to automatically extend out of the wheel chamber 11, providing stable movement support for the equipment in automatic cleaning mode. By reasonably setting the position of the connecting position, the elastic force of the elastic element 33 can be effectively utilized to achieve the extension and retraction of the drive wheel 32 with minimal torque. This layout not only simplifies the mechanical structure but also improves the reliability and stability of the operation.
[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, the handle assembly 2 includes a handle 21 hinged to the body 1, a first connecting rod 22 connected to the handle 21, two linkage rods 23 with one end respectively hinged to both ends of the first connecting rod 22, and two second connecting rods 24 respectively hinged to the other end of each linkage rod 23. The linkage rods 23 are provided with limiting protrusions 231, and the body 1 is provided with limiting grooves 13 for sliding the limiting protrusions 231.
[0033] In this embodiment, the handle 21 is hinged to the body 1 and connected to two linkage rods 23 via a first connecting rod 22. The other end of the linkage rod 23 is hinged to a second connecting rod 24. When the handle 21 is lifted, the first connecting rod 22 moves accordingly, causing the limiting protrusion 231 on the linkage rod 23 to slide within the limiting groove 13 of the body 1. This action is transmitted to the release mechanism 4 via the second connecting rod 24, thereby restricting the drive wheel 32 of the roller assembly 3 from extending out of the wheel chamber 11, allowing the equipment to operate in manual mode and preventing friction and entanglement between the wheel and the bed surface. When the handle 21 is released, the limiting protrusion 231 slides to another position, the release mechanism 4 releases the restriction on the roller assembly 3, and the drive wheel 32 automatically extends out of the wheel chamber 11 under the action of the elastic member 33, allowing the equipment to operate in automatic mode.
[0034] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the release mechanism 4 includes a release push block 41 connected to the second connecting rod 24 and a limiting block 312 disposed on the rotating member 31. The release push block 41 abuts against the limiting block 312 to restrict the drive wheel 32 from extending out of the wheel chamber 11.
[0035] In this embodiment, the release push block 41 is connected to the second connecting rod 24 and moves with the movement of the handle assembly 2, while the limiting block 312 is fixed to the rotating member 31. When the handle 21 is lifted, the coordinated movement of the first connecting rod 22 and the linkage rod 23 pushes the second connecting rod 24, thereby causing the release push block 41 to abut against the limiting block 312, thus restricting the rotation of the rotating member 31 and keeping the drive wheel 32 within the wheel chamber 11, facilitating manual handling or adjustment of the equipment. When the handle 21 is released, under the action of gravity or elastic restoring force, the release push block 41 disengages from the limiting block 312, releasing the restriction on the rotating member 31. The drive wheel 32 automatically extends out of the wheel chamber 11 under the action of the elastic member 33, and the equipment can operate in automatic mode.
[0036] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the body 1 is provided with a sliding groove 14 for maintaining the second connecting rod 24 to move back and forth in the horizontal direction, and a through hole 15 for the release push block 41 to extend into or out of the wheel chamber 11.
[0037] In this embodiment, the design of the sliding groove 14 ensures that the second link 24 can move back and forth in the horizontal direction without deviating from the predetermined trajectory. By limiting the movement direction of the second link 24, the sliding groove 14 effectively reduces the mechanism jamming or misalignment caused by the deviation of the operating force, thereby improving the smoothness and reliability of the equipment operation. At the same time, the through hole 15 allows the release push block 41 to extend into or out of the wheel chamber 11 when needed, and to abut or disengage from the limiting block 312, thereby controlling the extension and retraction state of the drive wheel 32.
[0038] Furthermore, as a preferred embodiment of this solution and not a limitation, the limiting groove 13 includes a first limiting 131 and a second limiting 132. The limiting protrusion 231 slides to the first limiting 131. At the same time, the linkage rod 23 drives the second connecting rod 24 to cause the release push block 41 to abut against the limiting block 312 to restrict the drive wheel 32 from extending out of the wheel chamber 11. The limiting protrusion 231 slides to the second limiting 132. At the same time, the linkage rod 23 drives the second connecting rod 24 to cause the release push block 41 to disengage from the limiting block 312 to release the restriction on the drive wheel 32 extending out of the wheel chamber 11.
[0039] In this embodiment, precise control of the mechanical movement position is achieved through the cooperation of the limiting groove 13 and the limiting protrusion 231, as well as the transmission characteristics of the linkage mechanism, thus realizing efficient control of the release mechanism 4. This layout not only simplifies the equipment structure but also improves the consistency and repeatability of the actions, providing a strong guarantee for the stable operation of the equipment.
[0040] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the body 1 is provided with a guide groove 16 that abuts against the first connecting rod 22. The guide groove 16 includes a first guide position 161 corresponding to the first limit 131 and a second guide position 162 corresponding to the second limit 132.
[0041] In this embodiment, the first link 22 is ensured to move along a predetermined trajectory during operation, forming a dual positioning mechanism with the cooperation of the limiting groove 13 and the limiting protrusion 231. When the handle 21 is lifted, the first link 22 moves to the first guide position 161 under the guidance of the guide groove 16, while the limiting protrusion 231 slides to the first limit 131. The linkage 23 and the second link 24 work together to push the release push block 41 to abut against the limiting block 312, restricting the drive wheel 32 from extending out of the wheel chamber 11. Conversely, when the handle 21 is released, the first link 22 moves to the second guide position 162 under the guidance of the guide groove 16, the limiting protrusion 231 slides to the second limit 132, the release push block 41 disengages from the limiting block 312, the drive wheel 32 automatically extends, and the equipment switches to automatic cleaning mode.
[0042] Furthermore, as a preferred embodiment of this solution and not a limitation, the handle 21 is lifted to cause the first connecting rod 22 to slide to the first guide position 161, and the handle 21 is released to cause the first connecting rod 22 to slide to the second guide position 162.
[0043] Furthermore, as a preferred embodiment of this solution and not a limitation, it includes two roller assemblies 3 respectively located on both sides of the body 1.
[0044] In this embodiment, two symmetrically arranged roller assemblies 3 provide balanced support for the device, ensuring smooth movement in automatic cleaning mode and reducing swaying and deviation caused by uneven force on one side. This layout not only improves cleaning efficiency but also enhances the device's ability to navigate complex terrains, such as uneven surfaces. The coordinated action of the two roller assemblies 3 achieves stable support and flexible steering during movement. Each roller assembly 3 has an independent drive wheel 32 and an elastic element 33, allowing for independent adjustment of its extension and retraction states to adapt to different usage scenarios and terrain conditions.
[0045] The working principle of this embodiment is as follows:
[0046] This application discloses a bed cleaning robot that achieves coordinated control of handle operation and wheel extension / retraction through a mechanical linkage design between a handle assembly and a roller assembly. After applying external force to press the roller assembly into the wheel chamber, when the handle assembly is manually lifted, the release mechanism, under traction, prevents the roller assembly from extending out of the wheel chamber, thus retracting it into the robot body. At this time, the handle provides a stable grip point for manual operation, eliminating interference from exposed wheels and preventing frictional resistance between the wheels and the cleaning surface. Conversely, when the handle assembly is released... The locking mechanism releases the constraint on the roller assembly, which automatically extends out of the wheel chamber under the drive of gravity or elastic reset mechanism. This ensures that the equipment has stable movement support and obstacle-crossing ability in automatic cleaning mode. At the same time, the handle assembly falls to the body to avoid snagging and tangling with flexible items such as sheets and duvet covers. This optimizes the functional compatibility of the equipment in manual and automatic modes, solving the defect of fixed handles interfering with the cleaning process and overcoming the pain point of difficult handling of handleless equipment. It significantly improves the ease of operation, mode switching efficiency and adaptability to multiple scenarios.
