TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to a washing machine hinged mechanism and a washing machine using the same. BACKGROUND

[0002] As an efficient ground cleaning tool, the washing machine is widely used in commercial, industrial and home environments. In its actual application feedback, there is a common problem of insufficient flexibility, especially in narrow spaces or complex environments, where turning operations become difficult and laborious.

[0003] The rigid chassis structure and fixed position cleaning components (such as brush discs) of traditional washing machines limit their overall flexibility. The size of the vehicle body, weight distribution, and the layout of the cleaning components all work together to make it difficult for the machine to respond quickly and accurately when making complex turns.

[0004] In addition, although the handle of the existing small washing machine can adjust the angle within a certain range, it lacks freedom in three-dimensional space and cannot achieve true omnidirectional rotation, resulting in the operator having to rely on the strength of both hands when changing direction, increasing the difficulty of operation and physical exertion. CONTENT OF THE INVENTION

[0005] To solve the above problems, the present application provides a washing machine hinged mechanism and a washing machine using the same, which aims to achieve omnidirectional rotation function by freely rotating the handle in multiple directions, improve the operation flexibility of the washing machine, and reduce the physical exertion of the operator.

[0006] To achieve the above purpose, the present application adopts the following technical solutions:

[0007] In a first aspect, the present application provides a washing machine hinged mechanism, which comprises a handle connecting rod, a T-shaped steering shaft, a positioning plate fixed to the upper end of the machine body and positioning the T-shaped steering shaft, and a hinged seat.

[0008] The T-shaped steering shaft comprises a first boss portion connected to the handle connecting rod and allowing the handle connecting rod to rotate left and right, and a second boss portion provided on the left and right sides of the first boss portion and connected to the hinged seat and allowing the first boss portion to rotate forward and backward.

[0009] The hinged seat is fixed on both sides of the positioning plate, and the hinged seat is provided with a first hole slot portion inserted into the second boss portion and allowing it to rotate.

[0010] The hinge mechanism of the present application is used to connect the handle and the body, so that the handle can be conveniently rotated to operate the direction of the scrubber. Specifically, the T-shaped steering shaft realizes the true universal rotation function, so that the handle can be freely adjusted in the left and right and front and rear directions, and the operator can easily complete various complex steering actions without changing the body posture, which not only improves the work efficiency, but also reduces the physical consumption.

[0011] In some possible embodiments, a first ball plunger is further arranged between the handle connecting rod and the first boss portion, the bottom of the handle connecting rod is provided with a second hole groove portion for mounting the first ball plunger, and the bottom of the first boss portion is provided with a semispherical first recess for mounting the other end of the first ball plunger.

[0029] The features of the present application and other related features are further described in detail below by way of examples, so as to facilitate the understanding of the skilled in the art:

[0030] It should be noted that the words "left", "right", "upper" and "lower" 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.

[0031] Further, unless otherwise clearly specified and limited, the terms "mounting", "connecting", "connection" should be interpreted broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0032] In addition, the terms "horizontal", "vertical", "perpendicular" and the like do not mean that the components must be absolutely horizontal or perpendicular, but can be slightly inclined. For example, "horizontal" only means that it is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0033] In practical application and operation of the scrubber, most scrubbers have the problem of insufficient flexibility, especially in narrow spaces or complex environments, the steering operation becomes difficult and laborious. Mainly, the rigid chassis structure and fixed position cleaning components (such as brush disc) of the traditional scrubber limit the overall flexibility, making it difficult to quickly and accurately respond when making complex turns. The size of the vehicle body, weight distribution, and the connection method of the handle further exacerbate the problem.

[0034] To solve this problem, the present application mainly starts from the hinge method of the handle and the optimization design of the chassis structure to improve the steering flexibility of the entire scrubber.

[0035] Please refer to Figure 1 The scrubber of the present application is provided with a machine body 10, and the handle 2 is connected with the machine body 10 through the scrubber hinge mechanism 1. Please refer to Figure 1 and Figure 2 The machine body 10 includes a water tank 3, a chassis assembly 4, a brush disc system 5 as a working system and driven by a motor, a front universal wheel 6 playing a guiding role, an air suction system 7 for sucking sewage, dirt and other debris generated during cleaning from the ground, and a motor case 8. At this time, the scrubber hinge mechanism 1 is preferably installed at the upper end of the motor case 8. Of course, it can also be installed at a position convenient for operation according to the configuration of the machine body 10.

[0036] As a preferred configuration, please refer to Figure 2 and Figure 7 , Figure 8 The chassis assembly 4 includes a main plate 41, an axle 42 penetrating through the bottom of the main plate 41, and large wheels 43 arranged at both ends of the axle 42.

[0037] Preferably, the main plate 41 is made of aluminum alloy sheet metal and is bent. The axle 42 will be inserted through the hole of the large wheel 43 and the side of the main plate 41, and then the side wall of the axle 42 will be locked with screws. At this time, the screws and the main plate 41 will limit the lateral movement of the large wheel 43.

[0038] Further, the large wheel 43 is internally provided with a rolling bearing. When the large wheel 43 rotates, the rolling bearing is driven to rotate internally, so that the axle 42 can remain stationary while the large wheel 43 rotates, reducing the wear of the axle.

[0039] In some embodiments, the wheel shaft 42 is installed with a water suction system 9, which can effectively collect sewage and dirt, assist the air suction system, and improve cleaning efficiency.

[0040] The following describes the articulated mechanism 1 of the scrubber in detail. Please refer to Figure 3 The articulated mechanism 1 of the scrubber includes a handle connecting rod 11, a T-shaped steering shaft 12, a positioning plate 13, and a hinge base 14. The positioning plate 13 is fixed to the upper end of the machine body 10 and positions the T-shaped steering shaft 12.

[0041] Specifically, the T-shaped steering shaft 12 includes a first boss portion 121 at the upper end connected to the handle connecting rod 11 and enabling the handle connecting rod 11 to rotate left and right. On the left and right sides of the first boss portion 121 are provided second boss portions 122 connected to the hinge base 14 and enabling the first boss portion 121 to rotate forward and backward. The second boss portions 122 are cylindrical bosses. That is, the hinge base 14 is two, respectively on the left and right sides of the positioning plate 13 and fixed to the machine body 10. The hinge base 14 is provided with a first hole groove portion 141, and the second boss portions 122 rotate within the first hole groove portion 141 to realize the forward and backward rotation of the first boss portion 121, that is, the first boss portion 121 also drives the handle connecting rod 11 to rotate forward and backward.

[0042] The rotation of the handle connecting rod 11 enables the first boss portion 121 to be a semicircular boss with a left-right direction open cutout 123 in the middle, which is used to fit the handle connecting rod 11. A pin shaft hole 126 is provided in the upper part of the first boss portion 121, which is a circular through hole. Correspondingly, a connecting through hole 172 is provided in the handle connecting rod 11, which is rotatably connected to the first boss portion 121 through a pin shaft 17. The pin shaft 17 is a stainless steel support, which is locked by a circlip 171 after passing through the pin shaft hole 126 of the first boss portion 121 and the connecting through hole 172. At this time, the handle connecting rod 11 can rotate around the pin shaft 17.

[0043] In this way, the handle 2 and the machine body 10 can be connected through the articulated mechanism 1, so that the handle 2 can be conveniently rotated to operate the direction of the scrubber. As described above, the T-shaped steering shaft 12 can realize the universal rotation function in the left-right and forward-backward directions, so that the operator can easily complete various complex steering actions without changing the body posture, which not only improves the work efficiency, but also reduces the physical consumption.

[0044] In specific use, a certain pre-tightening force is required for universal rotation to maintain the stability of the force during work and to maintain the position of the handle 2 during storage.

[0045] Specifically, please refer to Figures 3 to 6 A first ball plunger 15 is arranged between the handle connecting rod 11 and the first boss portion 121, and a second ball plunger 16 is arranged between the bottom of the first boss portion 121 and the positioning plate 13.

[0046] The first ball head plunger 15 and the second ball head plunger 16 are made of stainless steel, the upper part is a cylindrical plunger part, the lower part is a spherical head part, and a spring is arranged in the plunger part, which is an elastic structure. It can retract a certain distance in the pressure state.

[0047] In this way, the design of the ball head plunger makes the steering more smooth and natural, and the plunger part of each ball head plunger is arranged with a spring, which provides a pre-tightening force to ensure the close contact of the ball head in the groove and reduces looseness and unnecessary gaps.

[0048] The first ball head plunger 15 is connected by being inserted into the plunger part of the first ball head plunger 15 and bonded with glue at the bottom of the handle connecting rod 11 provided with a circular second hole groove part 111. Correspondingly, the first boss part 121 is provided with a hemispherical first groove 124 for mounting the other end of the first ball head plunger 15.

[0049] The second ball head plunger 16 is connected by being inserted into the plunger part of the second ball head plunger 16 and bonded with glue at the bottom of the first boss part 121 provided with a third hole groove part 125 for mounting the second ball head plunger 16. Correspondingly, the upper end of the positioning plate 13 is provided with a hemispherical second groove 131 for the other end of the second ball head plunger 16, which engages with the head part of the second ball head plunger 16.

[0050] Taking the second ball head plunger 16 as an example, when the T-shaped steering shaft 12 rotates forward and backward during work, the head part at the lower part of the second ball head plunger 16 will touch the edge of the second groove 131, and the head part will continue to rotate to the center of the second groove 131, and the spring inside the plunger part will be compressed. When it rotates to the center of the hemispherical second groove 131 of the positioning plate 13, the second ball head plunger 16 returns to the original length under the action of the spring inside the second ball head plunger 16, and the bottom end of the head part of the second ball head plunger 16 is attached to the bottom of the hemispherical second groove 131, as shown in the state. Figure 6 At this time, if no external force is applied, the T-shaped steering shaft 12 will remain in the current position. Similarly, when the handle connecting rod 11 rotates to the center of the first groove 124 at the bottom of the T-shaped steering shaft 12, it is also positioned here, which makes the scrubber in a stationary state to place the handle 2 vertically, without tilting, saving storage space.

[0051] As described above, the present application protects a scrubber articulation mechanism and a scrubber applying the same, and all technical solutions similar or similar to the present application shall be shown to fall within the protection scope of the present application.
