Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to the technical field of a driving motor with double output shafts in a counter-rotating mode and a cleaning mechanism. BACKGROUND

[0002] In the field of cleaning equipment, especially the scrubber for ground cleaning, the main function is to remove ground dirt through rotating brush head and to recycle the generated sewage. The traditional scrubber generally adopts single-rotating-disk design. When the scrubbing brush contacts with the ground and generates friction, the advancing direction of the scrubber will be deflected due to the asymmetric force, and the operator must exert additional force to maintain the straightness of the advancing direction, which not only increases the labor intensity, but also easily leads to the fatigue of the operator.

[0003] In view of this, the double-rotating-disk design of the scrubber appears in the market, but in most cases, the two rotating disks are driven by independent motors, forming two separate single-rotating-disk systems in essence. Although such design can improve the cleaning effect and efficiency to some extent, it is still difficult to completely avoid the deflection of the machine caused by the unbalanced friction force due to the control of two motors respectively, and the use of two independent motors will also cause the problems of cost increase, structural complication and energy consumption increase. CONTENT OF THE UTILITY MODEL

[0004] In view of the above problems, the present application provides a driving motor with double output shafts in a counter-rotating mode and a cleaning mechanism, which aims to provide a technical means capable of effectively reducing or even eliminating the deflection of the machine caused by the rotation of the brush head, so as to make the operation easy and convenient, reduce the labor intensity of the operator, and at the same time ensure that the cleaning efficiency and quality are not affected.

[0005] In order to achieve the above-mentioned purpose, the following technical solutions are adopted in the present application:

[0006] In a first aspect, the present application provides a driving motor with double output shafts in a counter-rotating mode, which comprises a motor body capable of double-end output, a steering gear set respectively arranged and connected at both ends of the motor body, and an outer shell encapsulating the motor body and the steering gear set;

[0007] The steering gear set comprises a first bevel gear connected with the motor body and a second bevel gear meshing with the first bevel gear and adjusting the output direction of the motor body by 90°;

[0008] Further comprising an output shaft connected with the second bevel gear.

[0009] The driving motor with double output shafts in a counter-rotating mode of the present application realizes synchronous rotation output at both ends through a single motor body, ensures that the brush heads on both sides work at the same speed and torque, significantly improves the cleaning efficiency and reduces the deflection of the machine, and reduces the labor intensity of the operator.

[0010] In some possible embodiments, a reduction gear set is further arranged between the two ends of the motor body and the steering gear set and distributed in a planetary manner around the main shaft of the motor body.

[0011] The reduction gear set effectively reduces the rotation speed and amplifies the torque, ensuring sufficient power even under high load conditions, and improving the cleaning efficiency and the stability of the machine operation.

[0012] In some preferred embodiments, the output shaft is a hexagonal boss with a fixed threaded hole in the middle.

[0013] In the second aspect, the application further provides a cleaning mechanism, which comprises the driving motor with double output shafts in a contra-rotating manner as described above, a flange plate mounted on the output shafts and rotating therewith, and a brush plate mounted on the flange plate and rotating therewith.

[0014] In this way, the motor output shafts and the brush plate are firmly connected by the flange plate, ensuring the efficiency and stability of power transmission. At the same time, the two output shafts rotate in opposite directions during operation, so that the brush plates contra-rotate. The contra-rotating brush plates can offset the friction deflection force generated by a single brush plate when washing the ground, making the direction of the cleaning mechanism more stable and easier to control during operation.

[0015] In some possible embodiments, the flange plate and the brush plate are connected by a magnetic force buckle arranged in a ring shape, and the bottom of the flange plate is fixedly connected with an iron ring.

[0016] During installation, the brush plate only needs to be placed close to the flange plate, and the two can be attracted under the action of magnetic force. When disassembling, the brush plate can be disassembled by bending it downward, greatly facilitating the disassembly and installation of the brush plate and saving time and effort.

[0017] In some possible embodiments, a motor mounting seat is further arranged between the driving motor and the flange plate, and the motor mounting seat is designed in an integrated U shape and is provided with a through hole through which the output shaft passes.

[0018] The integrated U-shaped design of the motor mounting seat provides stable support, ensures the accurate alignment between the driving motor and the flange plate, reduces vibration and noise during operation, and prolongs the service life of the equipment.

[0019] In some possible embodiments, a water spraying assembly is further arranged on the upper end of the motor mounting seat and supplies water to the brush plate, and the motor mounting seat is provided with a water inlet opening.

[0020] Specifically, the water spraying assembly comprises a T-shaped pipe connected with the water inlet pipe, a water distribution pipe connected with the T-shaped pipe and branched to two ends, and an L-shaped water outlet head connected with the other end of the water distribution pipe and passing through the water outlet opening. The L-shaped water outlet head is arranged at the lower end of the driving motor, which is compact and saves space.

[0021] Further, the middle part of the flange plate is provided with a hollow opening, and the water outlet end of the L-shaped water outlet head is arranged at the hollow opening of the flange plate, so that the water flow can flow through the flange plate to the ground in the central area of the brush plate, and water stains caused by uneven water supply can be prevented.

[0028] The features of the present application and other related features are further described in detail by the following examples, so as to facilitate the understanding of the skilled in the art:

[0029] It should be noted that the words "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom" and "top", "inner" and "outer" refer to the directions towards or away from the geometric center of a particular component.

[0030] Further, unless otherwise clearly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present case can be understood according to the specific circumstances.

[0031] Furthermore, the terms "horizontal", "vertical", "upright", and the like are used as terms of convenience to reference the orientation of components, and do not require the components to be absolutely horizontal or upright, but can be slightly tilted. For example, "horizontal" merely means more horizontal than "vertical", and does not require the structure to be absolutely horizontal, but can be slightly tilted.

[0032] Firstly, the cleaning mechanism of the present application can be applied to a scrubber, a traditional single-disc design scrubber, when the scrubbing brush, i.e. the brush disc, is in contact with the ground and generates friction, the scrubber will be deflected in the forward direction due to the asymmetric force, and the operator must exert additional force to maintain the straightness of the forward direction.

[0033] To this end, a double motor is selected to solve this problem. However, due to the separate control of the two motors, it is still difficult to completely avoid the deflection of the machine caused by the unbalanced friction force. The problem to be solved by the present application is the balance problem when selecting a double motor.

[0034] Please refer to Figures 1 to 4 The cleaning mechanism of the present application, i.e. the brush disc mechanism of the scrubber, includes a driving motor 1 capable of achieving synchronous output of double shafts, at this time the double shafts of the driving motor 1 are opposite in output. That is, the two output shafts 14 of the driving motor 1 are opposite in rotation, and a flange plate 2 rotating with the output shafts 14 is installed on the output shafts 14. At the same time, a brush disc 3 rotating with the flange plate 2 is installed on the flange plate 2, which is the part of the scrubber in contact with the ground. The brush disc 3 includes a shell part 31 and a fibrous plastic brush 32, and the plastic brush 32 is the part for cleaning.

[0035] Specifically, in combination with reference to Figure 5 The output shaft 14 of the driving motor 1 is a hexagonal boss with a fixed threaded hole 141 in the middle, and the mounting part of the flange plate 2 is a hexagonal groove with a circular opening at the lower part. When mounting, the hexagonal boss of the output shaft 14 of the driving motor 1 is inserted into the hexagonal groove in the center of the flange plate 2, and the screw is screwed into the fixed screw hole 141 of the output shaft 14 of the driving motor 1 after passing through the circular opening at the lower part of the flange plate groove. The hexagonal structure ensures that the output shaft 14 can drive the flange plate 2 to rotate, and the screw ensures that the flange plate 2 and the output shaft 14 of the driving motor are fixed in the up-down direction. The lower part of the flange plate 2 is circumferentially distributed around the central axis, and there are sixteen toothed bosses, which are used to engage with the brush disc 3 to drive the brush disc 3 to rotate circumferentially. The brush disc 3 has a groove corresponding to the clamping position.

[0036] Since the brush disc 3 is a component that needs to be frequently disassembled and washed, a quick disassembly structure is required. For this purpose, the top of the shell part 31 of the brush disc 3 is provided with 3 magnetic buckles 4, which are distributed on concentric circles with an angle of 120 degrees between adjacent magnetic buckles 4. The flange plate 2 is connected with the brush disc 3 through the annularly and uniformly distributed magnetic buckles 4, and in order for the flange plate 2 to be attracted to the magnetic buckles 4, an iron ring 21 is fixedly connected to the bottom of the flange plate 2.

[0037] When installing, the brush disc 3 only needs to be close to the flange plate 2, and under the action of magnetic force, the two can be attracted to each other. When disassembling, the brush disc 3 can be disassembled by bending it downward, which greatly facilitates the disassembly and installation of the brush disc 3, saves time and energy.

[0038] In this way, the firm connection of the flange plate 2 and the brush disc 3 can ensure the high efficiency and stability of the driving motor 1 with double shaft synchronous output. At the same time, the two output shafts 14 rotate in opposite directions during operation, so that the brush disc 3 rotates in opposite directions. The counter-rotating brush disc 3 can offset the friction deflection force generated by a single brush disc 3 when washing the floor, so that the direction of the cleaning mechanism during operation is more stable and the operation is more easy.

[0039] In actual application, the stable fixing relationship of the two output shafts 14 also affects the overall stability of the cleaning mechanism. For this purpose, a motor mounting seat 5 is provided between the driving motor 1 and the flange plate 2, which is designed in one-piece U shape and is provided with a through hole 51 through which the output shaft 14 passes. The one-piece U-shaped structure provides stable support, ensures the accurate alignment between the driving motor 1 and the flange plate 2, reduces vibration and noise during operation, and prolongs the service life of the equipment.

[0040] During specific installation, eight small through holes are opened on the U-shaped motor mounting seat 5 for fixing with the driving motor 1, and eight internally threaded holes are opened on the driving motor 1. During installation, the driving motor 1 is placed on the U-shaped motor mounting seat 5, and the screws are screwed into the screw holes of the driving motor 1 after passing through the through holes of the U-shaped motor mounting seat 5.

[0041] In specific application, the scrubber needs water supply, and for this purpose, the cleaning mechanism of the present application further comprises a water spraying assembly 6 provided on the upper end of the motor mounting seat 5 and supplying water to the brush disc 3, and the motor mounting seat 5 is provided with a water inlet opening 52.

[0042] Specifically, the water spraying assembly 6 comprises a T-shaped pipe 61 connected with a water inlet pipe, a water distribution pipe 62 connected with the T-shaped pipe 61 and branched to both ends, and an L-shaped water outlet head 63 connected with the other end of the water distribution pipe 62 and passing through the water inlet opening 52. The L-shaped water outlet head 63 is arranged at the lower end of the driving motor 1, which is firm and space-saving.

[0043] Correspondingly, the middle part of the flange plate 2 is provided with a hollow opening 21, and the water outlet end of the L-shaped water outlet head 63 is arranged in the hollow opening 21 of the flange plate 2. When water is supplied, the main water inlet pipe is connected with a solenoid valve for controlling the opening and closing of water, and the water outlet position of the L-shaped water outlet head 63 is located in the opening area at the center of the flange plate 2, so that the water flow can flow through the flange plate 2 to the ground in the central area of the brush plate 3, and water stains caused by uneven water supply can be prevented. At the same time, the L-shaped water outlet head 63 is arranged at the lower end of the driving motor 1, which is compact and saves space.

[0044] The double-end output mode of the driving motor 1 will be described in detail as follows. Please refer to Figure 5 and Figure 6 .

[0045] The driving motor 1 of the present application is a double-output-shaft driving motor of a counter-rotating type, which specifically comprises a double-end output motor body 11, a steering gear set 12 arranged at each end of the motor body 11, and a shell 13 encapsulating the motor body 11 and the steering gear set 12.

[0046] The steering gear set 12 comprises a first bevel gear 121 connected with the motor body 11 and a second bevel gear 122 meshing with the first bevel gear 121 and adjusting the output direction of the motor body 11 by 90°. An output shaft 14 is connected with the second bevel gear 122.

[0047] In this way, the double-output-shaft driving motor of the counter-rotating type of the present application realizes synchronous rotation output at both ends through a single motor body 11, ensures that the brush heads on both sides work at the same speed and torque, significantly improves the cleaning efficiency, reduces the machine deviation, and reduces the labor intensity of the operator.

[0048] In some possible embodiments, a reduction gear set 15 is further arranged between the motor body 11 and the steering gear set 12 at both ends of the motor body 11 and planetarily distributed around the main shaft of the motor body 11. The reduction gear set 15 effectively reduces the rotation speed and amplifies the torque, ensures that sufficient power can be provided even under high load conditions, and improves the cleaning efficiency and the stability of the machine operation.

[0049] Specifically, the motor body 11 is located at the central position of the whole driving motor 1 and outputs power to both ends, the motor body 11 drives the reduction gear set 15, the reduction gears are planetarily distributed around the motor shaft, the reduction gear set 15 has the function of amplifying torque, the steering gear set 12 is composed of two bevel gears in the horizontal direction and the vertical direction, the first bevel gear 121 in the horizontal direction is coaxial with the motor body, the second bevel gear 122 in the vertical direction is coaxial with the output shaft 14, and the steering gear set 12 adjusts the output direction of the motor body 1 by 90°.

[0050] More specifically, the steering gear set 12 is distributed around the motor body 11 center symmetrically, the vertical direction second bevel gear 122 is fixedly connected with the output shaft 14, the lower end of the motor shell 13 is provided with the output shaft 14 which is distributed symmetrically left and right, the design makes the rotation direction of the two output shafts opposite, the counter-rotating output shaft 14 will drive the brush disc 3 of the scrubber to counter-rotate, the counter-rotating brush disc 3 will offset the friction deflection force generated by the single scrubbing brush when scrubbing, so that the direction of the scrubber when working is more stable, and the operation is more easy.

[0051] The steering gear set 12 is composed of two bevel gears, the steering gear set 12 is shaped as a rectangular body with chamfer, similar to a triangle with stable characteristics, so that the motor power transmission is more reliable and stable. At the same time, it is also convenient for the installation of the brush disc motor mechanism and the machine chassis.

[0052] In actual operation, the counter-rotating principle is as follows, the motor body 11 is started, drives both ends to operate, the power is transmitted to the reduction gear set 15, the reduction gear set 15 has the effect of reducing the rotating speed and amplifying the torque, the reduction gear set 15 transmits the power to the horizontal direction first bevel gear 121 in the steering gear set 12, the horizontal direction first bevel gear 121 drives the vertical direction second bevel gear 122, because of the symmetrical relationship of both ends, the rotation direction of the vertical direction second bevel gear 122 on both sides will be opposite, thereby driving the driving motor output shaft 14 to rotate in opposite directions.
