Description

TECHNICAL FIELD

[0001] The utility model relates to a floor washing robot technical field, concretely is a dust pushing mechanism of commercial floor washing robot. BACKGROUND

[0002] Commercial floor washing robot is the robot that provides service for commercial cleaning, can realize remote control operation, automatic driving, generally can set time and make an appointment to sweep, automatic charging, automatic water filling and drainage, automatic garbage dumping and so on, and is widely used in various commercial places, such as supermarket, shopping mall, hospital and so on;Commercial floor washing robot generally sets up dust pushing mechanism, can effectively capture and gather dust and particulate matter on the ground, when dust pushing mechanism pushes forward, dust cloth or brush head will contact the ground, and dust and particulate matter are pushed to the front or one side of robot, when dust and particulate matter are gathered and pushed to the direction of dust suction port or dust collecting box by dust pushing mechanism, robot will use the suction force generated by dust suction device, and the dust and particulate matter are sucked into dust suction port or dust collecting box.

[0003] Dust pushing cloth will lead to the decline of cleaning effect due to wear and tear, stain accumulation and other reasons after long time use. In order to maintain the best cleaning performance of floor washing robot, dust pushing cloth needs to be replaced, but a problem will be encountered, that is, the traditional dust pushing cloth is a single piece by piece, which is relatively short and independent, and once dirty, the device needs to be stopped for replacement, and the interval is short, which seriously affects the cleaning efficiency, and there is no early warning prompt when dust pushing cloth appears slack, breakage or exhaustion, which may cause the fluctuation of cleaning quality.

[0004] For example: a hospital outpatient department has put floor washing robots on each floor, and the floor washing robots move around on their respective floors, cleaning the ground in the moving process, and the personnel flow of some floors is large, so the dust pushing cloth becomes dirty quickly, at this time, the staff needs to squeeze through the crowd to find the robot, and then stop it to replace the dust pushing cloth, the replacement interval is too short, which is troublesome and laborious, resulting in low cleaning efficiency of the robot. UTILITY MODEL CONTENTS

[0005] The utility model aims at overcoming the defects of prior art, adapting to the actual needs, and providing a power distribution box waterproof equipment to solve the technical problems that the replacement of the dust pushing cloth of the current robot is more troublesome and cumbersome, the replacement interval is short, and the cleaning efficiency is affected while wasting manpower.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A dust mop mechanism for a commercial floor cleaning robot is designed, including a floor cleaning robot body and a support frame. An indicator light is fixedly connected to the outer wall of the floor cleaning robot body. A groove is formed on the surface of the support frame, and a push-button switch is fixedly connected to the inner side of the groove. A dust mop frame is fixedly connected to the bottom end of the support frame, and two support brackets are fixedly connected to the top end of the dust mop frame. An electric push rod is fixedly connected to the top end of the support bracket, and the telescopic end of the electric push rod passes through the surface of the support bracket and is fixedly connected to a pressure block. A cam is rotatably connected to the side wall of the support bracket, and a third rotating rod is fixedly connected to the outer surface of the cam. The third rotating rod is connected to the first rotating rod via a second synchronous belt. A squeeze switch is provided on both the upper and lower sides of the cam.

[0007] In this solution, the cam rotates during the replacement process. As it rotates, the cam repeatedly touches the pressure switch that controls the extension and retraction of the electric push rod, thus releasing the dust mop cloth and loosening the clamp. After the dust mop cloth is moved and replaced, it is pressed down and clamped again. This design not only significantly extends the dust mop cloth replacement interval but also effectively avoids the loosening problem caused by ground friction in traditional fixed dust mop cloths through dynamic tension adjustment. Simultaneously, a push-button switch is installed in the groove of the support frame. The dust mop cloth passes over the push-button switch from above. If the dust mop cloth loosens due to an accident or is fully released, the taut cloth loses its pressure on the push-button switch, causing it to spring back and activate the indicator light circuit. The indicator light flashes to prompt staff to handle the situation promptly, improving overall cleaning efficiency.

[0008] Preferably, the pressing end of the squeeze switch is fixedly connected to a pressing plate, the upper squeeze switch is fixedly connected to the bottom surface of the protruding part of the side wall of the support frame, and the lower squeeze switch is fixedly connected to the top surface of the support frame.

[0009] In practical applications, the pressing plate covers the cam, so that the cam can immediately squeeze the squeeze switch when it rotates, avoiding delays that could cause the dust mop cloth to be pulled.

[0010] Preferably, two top support plates are fixedly connected to the top edge of the main body of the floor cleaning robot, and two bottom support plates are fixedly connected to the bottom of the main body of the floor cleaning robot directly below the top support plates. A rotating rod is rotatably connected to the surface of the opposite side of the two top support plates through a bearing seat. A fixing groove is fixedly connected to the end of the rotating rod facing the support frame.

[0011] In practical applications, the No. 1 rotating rod can not only drive the No. 1 fixed groove and the release roller to rotate, but also drive the No. 2 rotating rod below and the No. 3 rotating rod on the side to rotate through two synchronous belts, so that they can be connected to each other to complete the release, rewind and clamping operations.

[0012] Preferably, a second rotating rod is rotatably connected to the surface of one of the bottom support plates via a bearing seat. The end of the second rotating rod facing the support frame is fixedly connected to a corresponding second fixing groove. A servo motor is fixedly connected to the outer wall of the other bottom support plate. The tail end of the drive shaft of the servo motor passes through the surface of the bottom support plate and is fixedly connected to the corresponding second fixing groove.

[0013] In practical applications, servo motors, through precise control, simultaneously drive the release roller, take-up roller, and cam to rotate, thus eliminating the need for additional drive equipment, reducing operating costs and power waste.

[0014] Preferably, the first rotating rod and the second rotating rod on one side of the second synchronous belt are connected by the first synchronous belt drive, and the support frame sidewall on one side of the groove is movably inserted with a plate.

[0015] In practical applications, the No. 1 and No. 2 rotating rods are the same size, so their rotation speeds are the same, ensuring that the release and retraction lengths are consistent. Furthermore, the insert plate can replace the dust mop cloth to squeeze the button switch, making it convenient to turn off the lifting light during replacement, thus avoiding extra power waste and accidental activation.

[0016] Preferably, a release roller is detachably connected between the two first fixing slots by bolts, and a take-up roller is detachably connected between the two second fixing slots by bolts.

[0017] In practical applications, the release roller and take-up roller are very easy to assemble and disassemble. Therefore, during use, once the dust-pushing cloth has been released, new release rollers and take-up rollers can be quickly replaced, which improves the convenience and practicality of the device.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model replaces the dust mop cloth by releasing and rewinding it. The dust mop cloth grows longer, and the part in contact with the ground is slowly replaced during the cleaning process, thereby extending the replacement interval and improving cleaning efficiency. At the same time, the replacement process drives the cam to rotate. During the rotation, the cam continuously touches the squeezing switch that controls the extension and retraction of the electric push rod, thereby releasing the clamp when the dust mop cloth is released. After the dust mop cloth moves and is replaced, it is pressed down and clamped again. This design not only significantly extends the dust mop cloth replacement interval, but also effectively avoids the loosening problem caused by ground friction of traditional fixed dust mop cloths through dynamic tension adjustment, ensuring that the dust mop cloth is always in the best working condition during the cleaning process, significantly improving cleaning efficiency and equipment operation continuity.

[0020] 2. This utility model features a push-button switch installed within a groove in the support frame. The dust mop cloth passes over the switch from above, pressing it. When the dust mop cloth loosens or releases due to unforeseen circumstances, the taut cloth loses its pressure on the switch, causing it to spring back and activate the indicator light circuit. The indicator light then flashes to alert staff to take timely action. This real-time pressure feedback from the dust mop cloth to the push-button switch in the groove provides proactive early warning of abnormal conditions, minimizing cleaning interruptions and improving overall cleaning efficiency.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] Example 1: A dust mopping mechanism for a commercial floor cleaning robot, see [link / reference] Figures 1 to 4The system includes a floor cleaning robot body 1 and a support frame 7. An indicator light 101 is fixedly connected to the outer wall of the floor cleaning robot body 1. A groove 701 is formed on the surface of the support frame 7. A push-button switch 702 is fixedly connected to the inner side of the groove 701. The pressing end of the push-button switch 702 extends out of the groove 701 and is pressed by the dust mop cloth passing above, thereby disconnecting the circuit. When the dust mop cloth becomes loose or breaks due to an accident, the push-button switch 702 will be released and pop up, connecting the circuit of the indicator light 101, causing the indicator light 101 to flash to alert the surrounding staff to deal with the situation in time, ensuring the normal operation of the device. A plug plate 703 is movably inserted into the side wall of the support frame 7 on one side of the groove 701. The plug plate 703 can temporarily replace the dust mop cloth to squeeze the push-button switch 702 when the staff removes or installs the dust mop cloth, thereby avoiding extra power consumption.

[0028] It should be noted that the push-button switch 702 is a device that switches a circuit on or off by pressing it. Its internal design ensures that when the switch is pressed, the contacts open, creating an open circuit and thus cutting off power; when the switch is released, the contacts close, connecting the circuit and allowing power to flow. This type of switch is simple and intuitive to operate and is widely used in various electronic devices, such as power switches for household appliances and start / stop controls for automated equipment. The push-button switch 702 is located at the corner near the bottom of the support frame 7, where the dust mop cloth bends, making it relatively stable when taut, thus allowing for continuous pressure on the push-button switch 702.

[0029] It should be noted that the button switch 702 and the indicator light 101 can be connected by a wire, and then connected to the power supply equipment inside the main body 1 of the floor cleaning robot. Relays and wireless transmission devices can also be installed inside the floor cleaning robot, so that after the circuit is connected, a signal can be sent to the control center, allowing the control center to know the situation remotely, thus eliminating the need for manual operation and greatly reducing manpower consumption.

[0030] Meanwhile, a dust mop frame 8 is fixedly connected to the bottom of the support frame 7. The dust mop frame 8 is very close to the ground, and the dust mop cloth is attached to the bottom of the dust mop frame 8 and in contact with the ground, so as to clean the ground while moving. The top of the support frame 7 is fixedly connected to the edge of the main body 1 of the floor cleaning robot. Two support frames 9 are fixedly connected to the top of the dust mop frame 8. An electric push rod 10 is fixedly connected to the top of the support frame 9. The telescopic end of the electric push rod 10 passes through the surface of the support frame 9 and is fixedly connected to the pressure block 1001. The electric push rod 10 drives the pressure block 1001 below to move vertically. The pressure block 1001 is used to tightly squeeze the dust mop cloth, thereby improving the stability of the dust mop cloth and avoiding the dust mop cloth from being stretched and loosened due to friction with the ground to the greatest extent, so that the dust mop cloth can always be kept taut.

[0031] Specifically, such as Figure 4 As shown, a cam 11 is rotatably connected to the side wall of the support frame 9. A third rotating rod 111 is fixedly connected to the outer surface of the cam 11. The third rotating rod 111 and the first rotating rod 201 are connected by a second synchronous belt 14. A squeeze switch 12 is provided on both the upper and lower sides of the cam 11. A press plate 121 is fixedly connected to the pressing end of the squeeze switch 12. The upper squeeze switch 12 is fixedly connected to the bottom surface of the protruding part of the side wall of the support frame 9, and the lower squeeze switch 12 is fixedly connected to the top surface of the support frame 9. During the release and rewinding of the dust mop cloth, the second synchronous belt 14 causes the third rotating rod 111 and the cam 11 to rotate together. During rotation, the upper and lower pressure switches 12 are pressed respectively. The two pressure switches 12 control the extension and retraction of the electric push rod 10. As soon as the release roller 5 releases the dust push cloth, the cam 11 presses the pressure block 1001 away from the dust push cloth because it presses the pressure switch 12 that controls the retraction of the electric push rod 10. Then, as the rotation continues, it presses the pressure switch 12 that controls the extension, so that the pressure block 1001 presses the dust push cloth again, ensuring the stability of the dust push cloth. The process of the pressure switch 12 controlling the extension and retraction of the electric push rod 10 is the process of the motor inside the electric push rod 10 reversing, so the operation is relatively convenient.

[0032] It should be noted that the upper and lower extrusion plates enclose the cam 11, and the protruding part of the cam 11 is located exactly in the gap between the two extrusion plates. After the cam 11 rotates, it can immediately contact one of the extrusion plates, so that the electric push rod 10 retracts at the same time as the dust push cloth is released. After rotating half a turn, it disengages from the extrusion plate, so that the retraction of the electric push rod 10 stops, and then it will contact the other extrusion plate, so that the electric push rod 10 extends again until the pressure block 1001 presses the dust push cloth down again. In the whole process, the cam 11 rotates exactly one turn and returns to its original position, and the dust push cloth is exactly the length of the release roller 5 rotating one turn. The diameter of the third rotating rod 111 is also consistent with that of the first rotating rod 201, so as to ensure that the clamping is released when releasing and the clamping is pressed down again when stopping the release. In this process, it is only necessary to keep the servo motor rotating in a single full turn.

[0033] Specifically, such as Figure 1 and Figure 2As shown, a release roller 5 is detachably connected between two No. 1 fixing slots 202 by bolts, and a take-up roller 6 is detachably connected between two No. 2 fixing slots 302 by bolts. The release roller 5 and the take-up roller 6 are exactly the same size, and their assembly and disassembly are relatively convenient, thus facilitating the replacement of the used dust mop cloth. This replacement interval is greatly extended compared to a single piece of dust mop cloth, thereby reducing manpower consumption. Furthermore, fixing the dust mop cloth to the take-up roller 6 or the release roller 5 is also relatively easy; tools such as straps and clips can be used for fixation to ensure that the dust mop cloth is securely fixed during the release process. As long as it doesn't fall off; the dust mop cloth is wound onto the release roller 5, with one end passing over the surface of the support frame 7, around the front end of the dust mop frame 8, then adhering to the bottom of the dust mop frame 8, and finally wound onto the take-up roller 6. The first rotating rod 201 and the second rotating rod 301 on one side of the second synchronous belt 14 are connected by the first synchronous belt 13. The first rotating rod 201 and the second rotating rod 301 are exactly the same size, so under the drive of the first synchronous belt 13, the two rotate at the same speed. This ensures that the amount of dust mop cloth released is the same as the amount wound up, keeping the dust mop cloth taut.

[0034] It should be noted that the inner surfaces of the first synchronous belt 13 and the second synchronous belt 14 are provided with toothed grooves, which ensures precise transmission and reduces the likelihood of slippage, resulting in relatively high transmission efficiency. The outer surfaces of the first rotating rod 201, the second rotating rod 301, and the third rotating rod 111 are provided with the same toothed grooves at the contact points with their respective synchronous belts. Power transmission is achieved through the meshing of the toothed grooves, combining the advantages of belt drive, chain drive, and gear drive. This results in a larger transmission ratio and higher transmission power, thus preventing slippage.

[0035] Furthermore, two top support plates 2 are fixedly connected to the top edge of the main body 1 of the floor cleaning robot, and two bottom support plates 3 are fixedly connected to the bottom of the main body 1 of the floor cleaning robot directly below the top support plates 2. The surfaces of the two top support plates 2 on opposite sides are rotatably connected to a first rotating rod 201 through a bearing seat. The outer surface of the first rotating rod 201 is fixedly connected to the inner ring of the bearing seat, and the outer ring of the bearing seat is fixedly connected to the inner wall of the top support plate 2, thereby ensuring that the first rotating rod 201 can rotate without detaching from the top support plate 2. A first fixing groove 202 is fixedly connected to the end of the first rotating rod 201 facing the support frame 7. The first fixing groove 202 can ensure that after the release roller 5 is inserted, it fits the two ends of the release roller 5, thereby quickly positioning it. After the bolts are tightened, the stability of the release roller 5 can be ensured. The same applies to the take-up roller 6.

[0036] It is worth noting that one of the bottom support plates 3 has a second rotating rod 301 rotatably connected to its surface via a bearing seat. The end of the second rotating rod 301 facing the support frame 7 is fixedly connected to a corresponding second fixing groove 302. The outer wall of the other bottom support plate 3 is fixedly connected to a servo motor 4. The tail end of the drive shaft of the servo motor 4 passes through the surface of the bottom support plate 3 and is fixedly connected to the corresponding second fixing groove 302. The servo motor 4 drives the second fixing groove 302 to rotate, thereby driving the entire winding roller 6 to rotate, which in turn drives the release roller 5 and the cam 11 above to rotate, together completing the steps of release, winding, and pressing. The servo motor 4 is a geared motor, which dynamically adjusts the current according to the difference between the target position and the feedback value through the controller to ensure that the servo motor 4 accurately reaches and stably maintains the specified position. Therefore, it can be guaranteed that the cam 11 can return to its original position after rotation.

[0037] It should be noted that the floor cleaning robot has a complex structure, including a mobility structure such as omnidirectional wheels, allowing for flexible movement in different environments; a cleaning structure including a squeegee, roller brush, and side brushes, which clean the floor during movement; and a sensor module, such as photoelectric sensors, infrared obstacle sensors, anti-fall sensors, gyroscope sensors, lidar sensors, and cameras. These sensors are responsible for perceiving the surrounding environment, such as detecting obstacles, measuring distances, and creating room maps. They transmit the perceived information to the main control unit so that the robot can make corresponding decisions, such as obstacle avoidance and planning cleaning paths. The main control unit is responsible for controlling the machine's operation; an internal power system is also included to provide electrical energy; the entire robot also has other auxiliary components, such as a clean water tank, a wastewater tank, and filters, which work in conjunction with the cleaning mechanism to ensure efficient and continuous floor cleaning. Since the internal mechanisms of the main body 1 of the floor cleaning robot are publicly available technologies and not the technical solutions to be protected by this utility model, they are not shown in the accompanying drawings but are actually present, and therefore will not be described further.

[0038] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0039] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
