Description

Hand-held automatic floor mopping vehicle

Technical Field

The utility model belongs to environmental protection machinery, especially hand-held automatic mopping car.

Background

The long-strip-shaped plate frame type mop is a widely-used floor mopping tool for a long time, but the long-strip-shaped mop is troublesome to clean and troublesome to dewater after cleaning. In recent years, a plurality of patents about folding mops and folding mops products on the market appear, and the folding mops are used for expanding and lengthening a long strip-shaped mop when mopping the ground and folding and shortening the strip-shaped mop when cleaning, so that the volume of a cleaning pool is reduced, and water is saved. Such as: patent application No.: 200520086551.0, patent name: wide and narrow dual-purpose folding mop. However, one of the common disadvantages of these patents is: 1. for the three-section folded long mop, the main mop, namely the auxiliary mops hinged at two ends of the middle mop, has no strong support, and the auxiliary mops are supported only by hinging one corner of the auxiliary mop to one corner of the main mop. This causes the side of the secondary mop remote from the hinge to deflect during cleaning. Especially too much deflection when lifting the mop. The longer the mop, the more deflection. Because the height of the main and auxiliary mop shells is required to be increased by the hinge support, namely the height of the hinge is increased to be slightly stable, the hinge is arranged on the door frame, the hinge is firmly arranged on the upper and lower parts of the door and the door frame, namely, the hinge is arranged at a high distance between the upper and lower hinges, and the hinge has the same effect as the stabilizing effect of a long integral hinge. In the patent, the hinge is connected only by heightening the main and auxiliary mop shells, and the mop shells cannot be increased too high, so that the occupied space and the volume are too large. In the patent, only the rotary supports are arranged on both sides of the main mop in order to rotate and fold the auxiliary mops at both ends of the main mop around the hinge, and the auxiliary mops are not strongly supported. 2. The above patents are all manual folding mops, manual mops and manual cleaning, and can not be used for automatic folding, automatic cleaning and automatic mops which are operated by a mechanical mopping machine.

There are machines that automatically clean mops and automatically mop the floor, as described in patent application No.: 201710714564.5, patent name: an automatic cleaning mopping floor machine. But in these mopping machines: 1. the cleaning pool is not only rectangular or circular in structure, but also the mop must be lifted to a relatively high height and be put down from the upper opening of the cleaning pool. The mop strips are scattered, and when the mop strips are put down from the upper opening of the cleaning pool, the scattered mop strips at the periphery are blocked outside the cleaning pool by the shell wall of the upper opening of the cleaning pool. When the mop is put into the cleaning barrel from the upper opening of the cleaning barrel, some mop strips around the mop are blocked outside the wall of the upper side shell of the cleaning barrel, and people need to repeatedly press the mop by a left inclined rod and a right inclined rod in multiple directions to put the mop strips around into the cleaning barrel. 2. The mop bar is put into the cleaning pool from the upper opening of the cleaning pool, so that the mop bar is lifted too high by the lifting mechanism, the total height in front of the mopping machine is raised too much, the observation of a driver on the head of the mop head beside a wall and a barrier in the mopping field is seriously influenced, the seat of the driver is raised, and great inconvenience is brought.

Disclosure of Invention

The utility model aims to overcome the defects of the prior long strip-shaped grillage mop and provide a hand-held automatic mopping vehicle, which is hereinafter referred to as a mopping vehicle.

The utility model discloses a realize like this: a hand-held automatic mopping vehicle comprises a vacancy filling cleaning pool, an auxiliary handle gear device, a mop, a leaning frame, a clamping device, a handlebar deflection device, a handlebar alignment device, a rotating arm mechanism and a vehicle body. The filling-up cleaning pool comprises a filling-up shell, a filling-up sleeve and a filling-up sleeve lifting device. The upper part in front of the notch shell is provided with a notch. The filling-up sleeve is arranged outside the open shell and can move up and down. When the mop enters the gap-filling cleaning pool, the gap-filling sleeve is arranged below the cleaning pool, the gap in front of the upper part of the gap shell is opened, and the mop enters the gap-filling cleaning pool from the gap. When the mop is cleaned, the filling-in sleeve is surrounded outside the upper part of the open shell, and the gap above the open shell is closed. The mop is provided with an auxiliary handle gear device and a handle rod device. The handle device comprises a handle, a handle gear, a handle disc, a baffle disc and a sleeve. The handle bar gear, the handle bar disc, the baffle disc and the sleeve are connected to the handle bar. The auxiliary handle gear device comprises an auxiliary handle gear, a pressure plate, an auxiliary handle shell and a shell connecting shaft sleeve. The lower plate surface of the auxiliary handle gear connects the auxiliary handle shells at two sides into a whole. The mop adopts an integral mop which is composed of a main mop in the middle and a pair of auxiliary mops connected with the two ends of the main mop. The left and right auxiliary handles are respectively arranged in the auxiliary handle shells at the two sides. The front end of the auxiliary handle is always at the supporting position of the center of the shell plate of the auxiliary mop regardless of the unfolding or folding of the auxiliary mop. The leaning frame is provided with a leaning frame lifting device, a clamping device, a handle alignment device and a motor. The clamping device consists of a clamping jaw seat and a clamping jaw. The handle alignment device comprises a screw rod seat, a screw rod, a slide way, a nut sliding sleeve, a push pier, a screw rod gear, a screw rod motor, a sleeve and a chuck. The upper end and the lower end of the screw rod and the slide way are both arranged on a screw rod seat, and the screw rod seat is arranged on the leaning frame. The nut is installed on the lead screw, and the nut sliding sleeve is installed on the slide, and the nut links together with the nut sliding sleeve. The leaning frame lifting device comprises a lifting rack, a lifting slide block, a lifting slide shell, a lifting gear and a lifting motor. The handlebar deflection device consists of a seat tube, a shaft pin and a handlebar. The rotating arm mechanism comprises a pipe column, a main arm and a telescopic arm. The telescopic arm is installed in the main arm. The mop which is cleaned on the mopping vehicle is taken down by mopping personnel and is used for mopping floors in narrow intervals and with a large number of obstacles. The mopping vehicle can be used for mopping the floor by manually holding the mopping vehicle by hands, and can also be used for automatically mopping the floor in a wide area or an area with few obstacles. The leaning frame is connected with a plug buckle, and the positioning pin is inserted into the plug buckle when not used. When the mop is arranged on the mopping vehicle, the handle bar is in a non-deflection state, and the handle bar can be in a deflection state after the mop is taken off from the mopping vehicle. The leaning device is arranged on a lifting slide block of the leaning frame lifting device. In the handlebar deflection device, the upper end of a seat tube is hinged with the lower end of a handlebar by a shaft pin. The leaning device is two bent leaning frames which wind from the back of the leaning frame to the front of the leaning frame to lean the mop. The filling cleaning pool is called cleaning pool for short.

The utility model has the advantages that: 1. the mop can be clamped on the floor mopping vehicle for automatic cleaning and mopping, and the cleaned mop can be taken off for manually mopping the narrow area and the area with many obstacles. The mop which is manually dragged to be dirty can be clamped on the mopping vehicle for cleaning, so that the condition that the mop is dirty and cannot be cleaned for a long time because a plurality of rooms and corridors need to be dragged by one traditional mop is avoided. 2. Because the mopping vehicle has the remote control mopping function and the automatic mopping function, a cleaner can remotely control the mopping vehicle to automatically mop the floor in a wide area where the mopping vehicle repeatedly mops. 3. The mopping vehicle has the function of automatically following the person with the remote controller to walk, so that the cleaning person turns left and right from the corridor to enter each room, the mopping vehicle can automatically follow the floor to walk, and the mopping vehicle can mop the floor in the corridor and the wider room and provide convenience for the cleaning person to replace the cleaned clean mopping handkerchief at any time. Firstly, the efficiency is improved, and secondly, the floor is cleaner after mopping because the mop is frequently changed. 4. The gap filling cleaning pool is arranged, so that the problem that a part of the mop strip is blocked at the edge of the upper opening of the cleaning pool due to the fact that the mop strip is put into the cleaning pool from the upper opening of the cleaning pool in the traditional automatic cleaning mop machine is fundamentally solved. The mop strip enters the cleaning pool from the opening of the cleaning pool, and the opening is sealed by the filling sleeve without water leakage. After the cleaning is finished, the filling-up sleeve descends, the notch is opened again, and the mop is transferred out from the notch, so that the lifting height of the mop entering the cleaning pool is greatly reduced, and the space occupied by the front part of the vehicle body in the transfer mop is greatly reduced. 5. The automatic folding part of the mop is arranged, so that the mop can be automatically folded and shortened when the mop is cleaned, and the volume of the cleaning pool is greatly reduced. When mopping, the mop can be automatically unfolded to be lengthened, the mopping width is increased, and the full-automatic mechanical automatic operation is adopted, so that the working efficiency is greatly improved. 6. The mop rod needs to swing when the mop is used for mopping the floor manually, and a mop person needs to hold the mop rod to mop the floor obliquely instead of vertically. In order to ensure that the handlebar can deflect when being manually mopped, the handlebar deflection device is arranged. However, the rod cannot swing when being installed on the floor mopping machine to mop the floor, and the rod is required to be perpendicular to the floor to mop the floor, because the rod on the floor mopping machine can be clamped only in a vertical state, the rod can be transferred into a cleaning pool to clean and dewater when the rod moves forwards along with a vehicle to mop the floor. In order to ensure that the handle bar is vertical to the ground when the floor mopping machine mops the floor, the handle bar aligning device is arranged. The handlebar is changed from the state of deflection being possible to the state of deflection being impossible. Due to the arrangement of the rod deflection device and the rod alignment device, the mop can be clamped on the floor mopping machine to clean the floor, and the mop can be taken down to be manually mopped. Provides great convenience for environmental protection personnel. Particularly, the mop after being mopped manually and dirtied can be replaced by the mop after being cleaned at any time. Not only improves the work efficiency, but also makes the floor cleaner after mopping.

The unshown portions are described in fig. 2 to 5.

FIG. 2 is a schematic view of the mop and associated connectors on the mop. The mop selected for use in the utility model is a foldable mop, and the prior foldable mop has various structures. The utility model selects three-section folding mop, and sets the automatic folding device and the handle bar device of the mop according to the selected mop. The first diagram is a front view, the second diagram is a top view, and the third diagram is an enlarged view of A-A of the first diagram. The figure D shows the structure of the handlebar deflection device. The mop is a group of integral mops formed by connecting a main mop and two auxiliary mops together. In the figure, the middle is a main mop, and the two ends are auxiliary mops. Each mop consists of a shell plate, namely a main shell plate 26, an auxiliary shell plate 22, a mop bar frame 23, a mop bar 16 and a handle rod device. The handle rod of the main mop is a handle rod 6, and the handle rod 6 is a circular tube. The handle rod of the auxiliary mop is an auxiliary handle 12, and the auxiliary handle 12 is transversely arranged on the main mop and the auxiliary mop.

A short shaft, i.e. a connecting shaft 24, is connected to the upper center of the sub-shell plate 22. The outer end of each auxiliary handle is connected with a connector 25, and a shaft hole matched with the connecting shaft 24 is formed in the connector 25. The connecting head is equivalent to a sleeve of the connecting shaft. The connecting shaft 24 is installed on the connecting head 25 through the shaft hole on the connecting head, and a clamping ring is installed at the upper end of the corresponding short shaft above the connecting shaft protruding out of the connecting head. A clearance for rotation fit is arranged between the shaft sleeve of the connector and the connecting shaft, and when the auxiliary mop is folded, the connecting shaft and the connector can rotate mutually. The edges of the connector, the auxiliary handle shell and the auxiliary handle are all chamfered and smooth. The upper part of the main mop is provided with a handle bar 6. The handle bar device comprises a handle bar 6, a handle bar disc 27, a handle bar gear 10, a baffle disc 28 and a sleeve 30 which are connected with the handle bar. Two chucks 29 are connected above the sleeve 30.

The auxiliary handle gear device comprises an auxiliary handle gear, a pressure plate, an auxiliary handle shell and a shell connecting shaft sleeve. In the third figure, an auxiliary handle gear 15 is arranged on the auxiliary handle shells 13 on two sides of the upper surface of the main mop, and the auxiliary handle shells on two sides are connected into a whole by the lower plate surface of the auxiliary handle gear 15. A shell connecting shaft sleeve 37 is arranged and connected between the two side auxiliary handle shells and in the center hole of the auxiliary handle gear. A seat tube 32 is attached to the upper central portion of the main housing plate 26. The upper end of the seat tube 32 is hinged with the lower end of the handle 6 by a shaft pin 31.

In the first drawing, the sub-handle 12 is mounted in the sub-handle case 13. The auxiliary mops 11 on both sides are in the unfolded state.

The second drawing is the top view of the first drawing, and the two auxiliary handles are parallel to each other. In the middle of the second drawing, only the auxiliary handle gear and the seat tube are drawn. The left end corner on the main shell plate is connected with the upper right corner of the left auxiliary shell plate by a hinge 33. The lower right-hand corner of the main shell plate is hinged with the lower left-hand corner of the right-hand sub-shell plate by a hinge 33, and the lower left-hand corner of the main shell plate is hinged with the lower left-hand corner of the right-hand sub-shell plate by a hinge 33.

In the first, second and third drawings, the auxiliary mop in the second drawing can be folded as long as the auxiliary handle gear rotates clockwise and the holding rod 6 does not rotate. The left sub-mop in the figure B rotates upwards and rightwards around the center of the hinge 33, and the right sub-mop rotates downwards and leftwards around the center of the lower hinge 33.

In the figure, the handlebar deflection device is shown. The handlebar deflection device consists of a seat tube, a shaft pin and a handlebar. The existing long handkerchief strip wide handkerchief mopping floor is provided with a stick deflection device. When the mop is used for mopping the floor manually, a mopping person holds the handle rod to mop the floor obliquely. The stick is not perpendicular to the ground, but has a certain deflection angle. The principle and structure of the handlebar deflection device arranged between the mop and the handlebar matched with the moped are the same as those of the existing mop, two clamping blocks 83 are connected to the lower end of the handlebar, a shaft tube connecting block 85 is hinged between the two clamping blocks 83 through a cross shaft pin 86, and two ends of the cross shaft pin 86 are fixed and cannot slip. A section of axle tube is connected below the axle tube connecting block 85. The upper end of the seat tube 32 is drilled with an axle pin hole and a counterbore. The shaft tube is placed between two shaft pin holes on the seat tube, a shaft pin with a specific length penetrates through the shaft pin holes and the shaft tube hole of the shaft tube, and then two ends of the shaft pin are fixed in countersunk holes on the seat tube. The fixing method can be realized in various manners, and riveting or spot welding manners are all possible. But the rivet head or the crater must be polished clean and smooth and cannot exceed the outer circular surface of the seat pipe. The cross pin 86 and the pin 31 are perpendicular to each other. The outer diameters of the handle bar 6 and the seat tube 32 are equal. There is a proper sliding fit clearance between the sleeve 30 and the handle bar and seat tube. The sleeve 30 is retained by a retaining ring 81 fixed to the handle after it has been moved up into position on the handle as shown in the first drawing. A friction fixing device 82 is arranged below the retainer ring, and the friction fixing device has the function that when the sleeve is pushed to move upwards to a proper position and is blocked by the retainer ring, the sleeve cannot automatically slide downwards. Friction fixing devices are available in various configurations, such as mounting a high friction material between the stick and the casing or mounting a spring leaf or spring wire within the stick. The friction fixing device is in a spring mode, a proper notch is formed in the handle at the position of the friction fixing device in the drawing, the spring steel wire is made into a wave-shaped bulge, and the wave-shaped bulge penetrates through the notch to expose proper upper and lower wave-shaped inclined planes. And a groove with proper depth and width is formed in the inner circle of the sleeve relative to the wave-shaped bulge, and when the sleeve goes upwards, the wave-shaped bulge steel wire is abutted into the groove, so that the sleeve is fixed. To make the sleeve go down, the upper inclined plane of the wavy steel wire can be pressed into the notch of the handle rod only by adding a certain pushing force, and the sleeve can go down. In the mode of installing the material with large friction force, a proper space is reserved between the inner diameter and the outer diameter of the corresponding position of the sleeve and the handle rod for installing the material with large friction coefficient. The lower end of the sleeve 30 is formed with an inner ring with a suitable bevel. The seat tube is not suitable to be overhigh, and theories and practices prove that the distance from the center of the shaft pin at the upper end of the seat tube to the main shell plate is less than half of the width of the mop, so that the manual mopping operation is convenient.

The following is described in conjunction with FIG. 5: in the first drawing of fig. 5, a bracket 57 on the right below the frame 2 is connected with a sub-handle motor 58, as shown in the second and third drawings of fig. 5. The bracket 57 of the sub-handle motor 58 is not shown in the first drawing for the sake of clarity of the lower drawing of the first drawing. The auxiliary handle motor is blocked by some figures on the mop in the first picture and cannot be seen. In the second drawing on the upper right, i.e. the enlarged view from D on the first drawing, and the third drawing on the lower right, i.e. the N drawing on the first drawing, it can be seen that the auxiliary handle motor 58 is supported to the right of the enlarged view from D by the bracket 57 connected to the rest frame 2, the motor gear 43 connected to the motor shaft thereof is meshed with the auxiliary handle gear 15, and the auxiliary handle gear and the two auxiliary handle shells and the auxiliary handle can be driven to rotate forwards and backwards. In the first drawing, the right side of the leaning frame is provided with a handle bar motor 9, and a motor gear 43 on the handle bar motor 9 is meshed with a handle bar gear 10. The handle gear 10 is integrally connected with the handle 6. When the motor of the handle bar does not rotate, but the motor gear is braked and does not rotate, namely the handle bar does not rotate, the motor of the auxiliary handle is electrified to rotate positively and negatively, and the auxiliary mops at the two ends of the main mop can be folded and unfolded.

A pedal 87 is arranged below the rear surface of the vehicle body 1, and a person can move along with the vehicle when standing on the pedal. The pedal can be folded.

In FIG. 2, the third drawing is an enlarged view of A-A in the first drawing, that is, a cross-sectional view in the width direction of the main mop. The main mop shell plate, namely the main shell plate 26, is provided with slide ways at two sides. The mop bar 16 is connected and fixed on the mop bar frame 23. The two sides of the handkerchief rack 23 are inserted into the slideways on the two sides of the main shell plate and fixed by a plurality of methods, such as fixing the main shell plate and the handkerchief rack by one screw. Auxiliary handles 12 are arranged in auxiliary handle shells 13 on two sides of the upper surface of the main shell plate. An annular space is arranged below the auxiliary handle gear 15 and close to the outer circle. The plate surface at the lower side of the auxiliary handle gear is connected with the upper surfaces of the auxiliary handle shells at the two sides into a whole. The inner circle of the auxiliary handle gear 15 is connected with the shell connecting shaft sleeve 37 into a whole. The connecting shell shaft sleeve is a common shaft sleeve of the auxiliary handle gear, the two auxiliary handle shells and the auxiliary handle. The lower end of the seat tube 32 is fixed at the center position on the upper surface of the main shell plate.

The upper plate surface of the auxiliary handle gear is provided with a circular step concave surface. The upper end of the pressure plate sleeve 38 is connected with the pressure plate 34. The lower end of the pressure plate sleeve 38 is fixed to the main housing plate 26 concentrically with the seat tube 32. The pressing plate 34 presses in a circular concave pit on the upper plate surface of the auxiliary handle gear. A proper rotating gap is arranged between the pressure plate shaft sleeve and the connecting shell shaft sleeve. A sleeve space 36 is reserved between the seat tube and the pressure plate shaft sleeve, namely when the sleeve in the T-picture descends, the sleeve can be sleeved on the outer circular surface of the seat tube and descends into the sleeve space.

In FIG. 3, the folding view of the sub-mop is shown. The first and second figures are drawn as the upper side of the shell plate of the mop. The first drawing is a development drawing of the sub-mop. The second picture is the folding process picture of the auxiliary mop.

As can be seen from the figure, the connecting heads of the outer ends of the two auxiliary handles are always supported at the central position of the auxiliary mop. The connection between the main mop and the auxiliary mop is unstable by the hinge connection on one corner of the rectangular shell plates of the main mop and the auxiliary mop. Because the shell plates of the main mop and the auxiliary mop cannot be made too thick, the height of one hinge is too small, and the deflection of the far end of the auxiliary mop is too large. The shell plate at the hinge position is easy to damage under the condition that the external force is slightly larger when the far end of the auxiliary mop is impacted in the mopping floor. In the figure, because the outer end of the auxiliary handle strongly supports the center of the auxiliary mop, the left and right auxiliary mops are much more stable and have much stronger external force interference resistance.

In the second drawing, when the left and right auxiliary mops are folded, the handle bar motor does not rotate, the handle bar 6 does not rotate, the mopping vehicle control center energizes the auxiliary handle motor, the auxiliary handle motor drives the auxiliary handle gear to rotate clockwise, and then drives the auxiliary handle shell and the auxiliary handle to rotate clockwise, namely drives the auxiliary mops at two ends to rotate clockwise around respective hinge centers. The two secondary mops are rotated from the dotted line position to the solid line position in the figure, so that the two secondary mops lean against the upper and lower sides of the main mops respectively. In the rotation process of the auxiliary mop, the length of the auxiliary handle extending out of the auxiliary handle shell is changed. The auxiliary handle is automatically extended or retracted in the auxiliary handle shell at proper time to adapt to the change of the length. When the auxiliary mop is folded in place, the auxiliary handles are retracted to the extreme positions in the auxiliary handle shell, the rear ends of the two auxiliary handles extend out of the edge line of the folded auxiliary mop by a certain length, but the length does not affect the cleaning of the folded mop group in the cleaning pool. As shown in fig. 6, the folded mop is rectangular, the rectangle is placed in the circular cleaning pool, and a large space is left at the side of the rectangle. As long as the rear end of the folded auxiliary handle does not extend out of the external circle of the folded rectangle, the mop can be cleaned in the cleaning pool without influence. When the auxiliary mop needs to be unfolded, the control center energizes the motor of the auxiliary handle to reversely rotate, and the auxiliary handle drives the two ends of the auxiliary mop to reversely rotate from the position of the second drawing to the position of the first drawing. The auxiliary handle motor has a self-locking function. Therefore, after the auxiliary mop is folded or unfolded, no additional locking device is needed. When the mop is long, a secondary sliding shell can be arranged between the rear section of the auxiliary handle and the auxiliary handle shell. After the secondary sliding shell is arranged, the problem that the rear end of the auxiliary handle extends out of the outer circle of the folded rectangle can be fundamentally solved. Two-stage slide cases are the current state of the art that is widely used today. The length of the mop is within one meter without adding a secondary slide shell. The length of the mop is determined according to the convenient use in the use environment.

Fig. 4 is a view showing the backrest frame and the mounting members attached to the backrest frame. The leaning frame is a pair of frames, and the frames and the brackets are designed according to the installation requirements of motors, clamping jaws, a leaning frame lifting device and the like arranged on the leaning frame. The drawings are described as simply showing a rectangular plate shape. The left side, namely the back side, of the leaning frame 2 is connected with a lifting sliding shell 42, and the lifting slide block 4 is arranged in the lifting sliding shell 42. The middle of the left side of the lifting sliding shell is open and not closed, as shown in the enlarged view of A-A at the lower part. In the rotating arm mechanism shown in fig. 1, the front end of a telescopic arm 3 is connected with the side of the left middle part of a lifting slide block 4 exposed out of a lifting slide shell into a whole. The right side of the lifting slide block is provided with a groove, a lifting rack 39 is arranged in the groove, and the lifting rack is lower than the outer plane of the groove. The backrest frame is provided with a lifting motor 41, as shown above the first drawing. The lifting gear 40 is connected on the shaft of the lifting motor. The left side of the lifting motor 41 enters the vacant position close to the frame plate line, and the motor shaft is vertical to the paper surface. The right side of the lifting sliding shell 42 is provided with a notch corresponding to the position of the lifting gear, and the lifting gear is meshed with the lifting rack on the lifting sliding block through the notch. The forward and reverse rotation of the lifting motor enables the leaning frame to ascend and descend.

The leaning frame is provided with a leaning frame lifting device, a clamping device, a handle alignment device and a motor. The clamping device consists of a clamping jaw seat and a clamping jaw. The leaning frame lifting device comprises a lifting rack, a lifting slide block, a lifting slide shell, a lifting gear and a lifting motor.

Two pairs of clamping jaw seats 44 are arranged on the leaning frame, and clamping jaws 8 arranged on the clamping jaw seats 44 are used for clamping the handlebar. When an operator puts the mop rod into the clamping openings of the two clamping jaws which are opened up and down, the opening clamping opening of the upper clamping jaw is larger than that of the lower clamping jaw. The operator first places the handle plate 27 on the upper side of the pole into the mouth of the upper jaw, and then holds the pole upward, i.e., the stop plate 28 on the pole is held upward against the underside of the lower jaw. The grip lever disk above the grip lever is now raised above the upper jaw. The operator positions the handle bar substantially centrally between the upper and lower jaws. The long edge of the mop is basically parallel to the leaning frame, and then the special key arranged on the leaning frame is pressed down by the other hand, so that the upper clamping jaw and the lower clamping jaw are folded to clamp the handle bar. The operator loosens his hands. At this time, a clearance for rotation fit is still left between the handle bar and the inner arc surfaces of the upper clamping jaw and the lower clamping jaw, and the handle bar is not clamped.

In the third view of fig. 4, the pressure plate 34 is provided with a positioning pin hole 56. In the third drawing of fig. 5, two inserting buckles 59 are connected to the right side of the backrest frame. A positioning pin 60 is inserted into the insertion buckle 59. If the operator wants to take off the cleaned mop to manually mop the floor, the operator first takes off the positioning pin 60 in the plug-in buckle 59 and inserts the positioning pin into the positioning pin hole 56 on the pressing plate, so that the unfolded mop can be positioned through the auxiliary handle gear and the auxiliary handle. The auxiliary handle can not rotate and swing, and can mop the floor. The positioning pin and the insert buckle as well as the positioning pin and the positioning pin hole are all provided with proper tightness, are not taken out manually and cannot fall out due to the vibration of the vehicle body.

In the figure, a leaning device is arranged below the leaning frame. The leaning device is arranged on a lifting slide block of the leaning frame lifting device. The leaning device is composed of two bent leaning frames which are wound from the back to the front of the leaning frame to lean the mop. A leaning frame 49 is connected and installed on the left surface of the part, exposed out of the lifting sliding shell, below the lifting sliding block 4, as shown in fig. 4C. The two centering frames 49 are divided into two after being connected from the left side of the lifting slider, and the two centering frames are respectively turned to extend to the right side of the leaning frame from the upper and lower sides in the third drawing, namely the two sides of the leaning frame in the first drawing. Two ends of the leaning frame are connected with touch plates 55, and the two touch plates are parallel to the leaning frame. The touch plate 55 is downwardly raised. At this time, the auxiliary mops at the two ends of the mop are in an open state. Two contact blocks 51 are arranged on the left straight surface of the auxiliary handle shell 13 on the left side of the mop in the figure. Since the sub-handle case is inclined to the main mop case plate in the longitudinal direction when the sub-mop is opened, the contact piece 51 of the sub-handle case 13 on the upper left side in the figure is made thinner than the contact piece on the lower side. The thickness of the upper and lower contact blocks is used to adjust the slightly deflected sub-handle shell to two contact surfaces parallel to the left leaning frame. In both the first and third views, the two contact blocks 51 are close to the contact plate 55. If only one touch block is close to the touch plate, the user needs to twist the handle rod, and when the two touch blocks are close to the touch plate, the mop is indicated to be right. At this time, the user presses a button on the vehicle body with the other hand, which indicates that the mop is aligned. The two clamping jaws clamp the bar instantly. The operator then withdraws the alignment pins from the alignment pin holes 56 in the platen and inserts them into the insert 59 against the back of the rack. The user finishes the process of installing and clamping the mop on the mopping vehicle. If the user does not pull out the positioning pin and insert the positioning pin into the corresponding insert buckle within a limited time, the mopping vehicle can generate a flashing light or a sound prompt. A small sensor is arranged in a plug-in buckle seat of the plug-in buckle, a short oblique swing block is arranged in the inner circle of the plug-in buckle in a deflection mode through the sensor, and when the positioning pin is inserted into the plug-in buckle, the swing block is naturally guided to be positive. The sensor is then connected to the circuit to generate a signal that is transmitted to the control center of the mopping vehicle. Then the process of aligning the handle bar and the seat tube is started.

The leaning frame is provided with a handle aligning device. The rod aligning device comprises a screw rod seat 46, a screw rod 52, a slide way 50, a nut 48, a nut sliding sleeve 47, a pushing pier 53, a screw rod gear 54, a screw rod motor 45, a sleeve 30 and a chuck 29. The upper and lower ends of the screw 52 are mounted in the screw base 46. Both screw bases 46 are mounted on the backrest. A slide way 50 is arranged between the upper screw rod seat and the lower screw rod seat, and a screw rod 52 is arranged on the right side of the slide way. The screw rod is provided with a nut 48, the left side of the nut 48 is provided with a nut sliding sleeve 47, and the nut sliding sleeve 47 is arranged on a slideway 50. The lead screw 52 and the slide 50 are parallel to each other. Two rings of chucks 29 are arranged on the outer circle of the sleeve on the handle. The right side of the nut is provided with a push pier 53, and the push pier 53 is clamped into a bayonet between the two chucks 29.

The two hinge shaft structures between the lower end of the handle bar and the seat tube are smaller than the excircle of the handle bar and the seat tube, and only the shaft pin 31 is used for representing the hinge in figure 4. The upper end of the screw rod penetrates through the screw rod seat and is connected with the screw rod gear 54. The leaning frame is provided with a screw rod motor 45, and a motor gear 43 on the screw rod motor is meshed with a screw rod gear 54. The positive and negative rotation of the screw motor 45 causes the nut to move up and down through the screw rod, thereby driving the sleeve 30 to move up and down. When the clamping jaws on the leaning frame clamp the handle bar, the handle bar and the seat tube are both vertically downward, and at the moment, the screw motor drives the nut to move downward, namely, the sleeve 30 moves downward and continuously descends through the hinged section to be sleeved on the outer circle of the seat tube. The small deviation between the seat tube and the handle bar caused by the hinge is rightly sleeved. In the first drawing of fig. 4, the nut is pushed against the abutment 53 between the two chucks 29 of the sleeve on the shaft, the lower end of the sleeve being above the pivot 31. The nut is also above.

In the second diagram in fig. 4, the feed screw nut drives the sleeve to move downwards, and the sleeve is sleeved on the seat tube, namely, the process of aligning the rod with the seat tube is completed.

In fig. 4, when the mop is hung and clamped, the rod is placed in the clamping jaws, when the rod is coiled on the upper clamping jaw and the baffle plate 28 is positioned below the lower clamping jaw, the clamping jaws are clamped together, and the push pier on the right side of the nut is naturally clamped between the two clamping chucks on the sleeve. The distance between the two chucks on the sleeve is a little bit larger than the thickness of the push pier.

If a user firstly uses the hand-push sleeve, the mop rod is vertically lifted by one hand. The other hand pushes the sleeve to move downwards to be sleeved on the seat tube, and then the handle rod is clamped on the leaning frame. At this time, another 'push pier downward moving' button on the vehicle body is pressed, the control center automatically energizes the lead screw motor, the nut is moved downward to a proper position, and the lead screw motor is powered off. When the user pushes the sleeve down to the right position, the push pier on the nut is clamped between the two chucks on the sleeve after the handle rod is clamped on the clamping jaw according to the method.

Fig. 5 is a partially enlarged view of fig. 4. The first drawing shows that the sleeve is lowered to cover the seat pipe and the nut and the sliding sleeve are lowered to the right position. The second diagram is the enlarged D-direction diagram of the first diagram. The third picture is the N picture of the first picture.

On the left side of the figure, it can be seen that most of the auxiliary handle motor 58 is blocked by the left side of the frame, and only a small part of the auxiliary handle motor and the motor gear can be seen. In the second drawing, it can be seen that a bracket 57 is connected to the side of the frame in the drawing, a sub-handle motor 58 and a motor gear 43 are connected to the bracket 57, and the motor gear 43 is engaged with the sub-handle gear 15. The upper surface of the sub-handle gear 15 is partially blocked by the jaw base 44 and the jaws 8.

Then the engaging process of the motor gear on the shaft of the handle motor 9 and the handle gear and the engaging process of the motor gear of the auxiliary handle motor and the auxiliary handle gear are carried out. The auxiliary handle motor and the handle bar motor both adopt servo motors with motor shafts capable of moving in a telescopic mode, just as the motor shafts of starting motors on automobiles can move in a telescopic mode, and just as the clutch between a starting motor gear and a starting gear of an automobile engine is completed by the movement of the motor gear. The diagrams A and B in FIG. 4 are also used as an example for description. In the first drawing, the motor gear of the handle motor is in a retracted state and is separated from the handle gear. When the sleeve is moved downwards to align the handlebar with the seat tube, the control system immediately energizes the motor of the handlebar, and the motor shaft and the motor gear of the handlebar move upwards at a slow rotating speed to be quickly meshed with the gear of the handlebar. Similarly, the control center energizes the auxiliary handle motor, and the motor gear of the auxiliary handle motor is meshed with the motor gear of the auxiliary handle motor according to the mode that the motor gear of the handle motor is meshed with the handle gear. After the motor gears of the handle bar motor and the auxiliary handle motor are jointed with the matched gears, the handle bar motor and the auxiliary handle motor are electrified and rotated according to a control program of a control center. At this time, the folding of the mop is completed first. The lifting motor 41 is electrified according to a program, so that the leaning frame and all the installation parts on the leaning frame are descended to a set height, and the contact block on the mop auxiliary handle shell is descended away from the contact plate on the leaning frame. The mop can rotate under the mop. The handle bar motor and the auxiliary handle motor have self-locking function after power failure, and can keep the motor gear not to rotate. The control center can cut off the power of the motor of the handlebar, so that the handlebar can not rotate. The control center energizes the auxiliary handle motor to rotate the auxiliary handle motor by a set angle according to a program in a set direction, namely, the auxiliary handle gear drives the auxiliary handle shell and the auxiliary handle to rotate from an unfolding position to an angle which is close to two sides of the main mop after being folded according to the auxiliary handle in the second diagram in figure 3, and the angle is called as a mop folding angle hereinafter. When the auxiliary handle motor makes the auxiliary handle gear drive the auxiliary handle to rotate to complete the 'mop folding angle', the auxiliary handle motor is powered off. At this time, the two clamping jaws are loosened according to the program to a certain extent, and the handlebar is not clamped any more, and a little rotating clearance is reserved on the handlebar.
