Referring to fig. 1 to 6, in an embodiment of the present invention, a cleaner housing latch structure includes:

an upper case 30 including a top plate 110, a first sidewall 120 and a second sidewall 130, wherein the first sidewall 120 and the second sidewall 130 are respectively located at two sides of a lower surface of the top plate 110, a free end of the first sidewall 120 along a length direction thereof is a first step structure 121, and a free end of the second sidewall 130 along a length direction thereof is a second step structure 131, wherein the first step structure 121 is formed by a size change of the first sidewall 120 in a height direction, and the second step structure 131 is formed by a size change of the second sidewall 130 in a height direction;

the top of the middle shell 200 supports the upper shell 30, a first clamping plate 210 matched with the first stepped structure 121 is arranged at a position on the middle shell 200 corresponding to the first stepped structure 121, and a second clamping plate 220 matched with the second stepped structure 131 is arranged at a position on the middle shell 200 corresponding to the second stepped structure 131.

The cleaning machine generally includes an upper housing 30, a middle housing 200, and a bottom housing, and in the mounting process, a radar assembly, a dust box assembly, etc. may be mounted on an upper surface of the middle housing 200, a drum brush assembly, a moving wheel assembly, etc. may be mounted on a lower surface of the middle housing 200, and then the upper housing 30 and the bottom housing are respectively closed with the upper surface and the lower surface of the middle housing 200, thereby forming a main body portion of the cleaning machine.

The first sidewall 120 and the second sidewall 130 may be separate structures or integrated structures connected to each other. In this embodiment, when the upper housing 30 is combined with the lower housing, two gaps are formed between the first sidewall 120 and the second sidewall 130, the two gaps are respectively located at the front end and the rear end of the cleaning machine, the two gaps are respectively an installation position of the anti-collision plate 400 and an installation position of the water tank 300, and the first sidewall 120, the outer wall of the water tank 300, the second sidewall 130 and the anti-collision plate 400 form an outer wall of the complete cleaning machine.

The "longitudinal direction" in the present embodiment is a direction extending along the edge of the upper case 30, and when the upper case 30 is circular, both the longitudinal direction of the first sidewall 120 and the longitudinal direction of the second sidewall 13 are the circumferential direction of the upper case 30.

When a user assembles the upper shell 30 to the middle shell 200, the cooperation of the first step structure 121 and the first snap-gauge 210 and the cooperation of the second step structure 131 and the second snap-gauge 220 form a similar meshing state in the alignment process of the upper shell 30 and the middle shell 200, so as to guide the upper shell 30 to be positioned in the middle shell 200, and play a positive role in guiding and positioning; and the first card 210 supports the first sidewall 120 well and the second card 220 supports the second sidewall 130 well.

In one embodiment, at least a portion of the first stepped structure 121 is snapped to an inner side of the first card 210 and/or at least a portion of the second stepped structure 131 is snapped to an inner side of the second card 220.

The inner side of the first card 210 and the inner side of the second card 220 are both sides near the center of the upper housing 30. And the engagement of the first stepped structure 121 with the inside of the first card 210 and/or the engagement of the second stepped structure 131 with the inside of the second card 220 restricts the swing of the upper case 30 on the middle case 200.

Referring to fig. 4, in one embodiment, the cooperation of the first stepped structure 121 and the first card 210 and the cooperation of the second stepped structure 131 and the second card 220 respectively limit the rotation of the upper case 30 in two directions relative to the middle case 200 in the circumferential direction.

Due to the structural features of the upper housing 30, the structural members thereof substantially include only the top plate 110, the first side wall 120 and the second side wall 130, so that the positioning of the upper housing 30 on the middle case 200 is easily displaced. In this embodiment, the first step structure 121 and the first catch 210 form a similar engagement fit and the second step structure 131 and the second catch 220 form a similar engagement fit, each of which can only restrict rotation of the upper housing 30 relative to the middle shell 200 in one direction (e.g., restrict rotation of the upper housing 30 in the clockwise and counterclockwise directions, respectively). That is, the cooperation of the first step-shaped structure 121 and the first card 210 cannot limit the separation of the first step-shaped structure 121 from the first card 210; the cooperation of the second stepped structure 131 with the second card 220 does not limit the separation of the second stepped structure 131 from the second card 220. By coordinating the step orientations of the first step structure 121 and the second step structure 131, the first step structure 121 and the first catch plate 210 and the second step structure 131 and the second catch plate 220 can be engaged to respectively limit the rotation of the upper housing 30 in two directions (clockwise or counterclockwise) relative to the middle housing 200, so that the upper housing 30 can be fixed on the middle housing 200 stably. That is, the cooperation of the first stepped structure 121 and the first card 210 restricts the separation of the second stepped structure 131 and the second card 220, and the cooperation of the second stepped structure 131 and the second card 220 restricts the separation of the first stepped structure 121 and the first card 210.

Referring to fig. 4, in one embodiment, the first step structure 121 and the second step structure 131 are disposed at positions that are bilaterally symmetrical on the lower surface of the top plate 110.

When the arrangement positions of the first stepped structure 121 and the second stepped structure 131 are symmetrical on both sides of the lower surface of the top plate 110, the direction in which the first stepped structure 121 is inserted into the first card 210 is the same as the direction in which the second stepped structure 131 is inserted into the second card 220, and at this time, the upper case 30 may be installed in place from the side or above the middle case 200; if the first step structure 121 and the second step structure 131 are asymmetrically disposed, the upper case 30 can be only loaded from the top of the middle case 200, and the appearance effect is not good.

Referring to fig. 5 to 6, in one embodiment, a protrusion 230 is provided on the top of the middle case 200, and a recess matching the protrusion 230 is provided on the surface of the top plate 110 facing the middle case 200.

The protrusion 230 on the middle shell 200 and the recess on the upper shell 30 are matched with each other to perform the alignment function, and at the same time, the matching degree between the middle shell 200 and the upper shell 30 is higher, so that the fixing stability of the upper shell 30 on the middle shell 200 is improved.

The protrusion 230 may be a structure designed simply to improve the degree of matching between the middle case 200 and the upper case 30, or may be a protrusion naturally formed due to the need to install other functional components in the middle case 200. For example, the cavity of the motor is mounted on the middle housing 200, and a protrusion structure is formed on the top of the middle housing 200, in this embodiment, the protrusion 230 is a dome-shaped structure formed to accommodate the roller brush motor (on the mounting frame of the roller brush assembly).

Referring to fig. 5, in one embodiment, the first card 210 has a first bent plate structure 211 in a length direction thereof and/or the second card 220 has a second bent plate structure in a length direction thereof.

In this embodiment, the first bending plate structure 211 and the second bending plate structure are respectively formed by non-smooth extension (for example, extension forming a broken line track) of the first card board 210 and the second card board 220 in the respective length directions. The first bending plate structure 211 and the second bending plate structure have the effect similar to a reinforcing rib due to the bending structures thereof, so that the strength of the first clamping plate 210 and the strength of the second clamping plate 220 are correspondingly improved. And due to the non-smooth extension of the first card 210 and the second card 220 in the respective length directions, their support to the respective first sidewall 120 and second sidewall 130 is also more stable.

For the wall thickness that increases first cardboard 210 and second cardboard 220, the setting of the first structure 211 of buckling and the second structure of buckling of above-mentioned has realized the increase of intensity and the improvement of support stability under the prerequisite that does not increase the material quantity.

Referring to fig. 4-5, in one embodiment, the first sidewall 120 has a first bent wall structure 122 along the length direction thereof, and the middle shell 200 is provided with a first protruding structure 240 matching with the first bent wall structure 122;

the second sidewall 130 has a second bent wall structure 132 along the length direction thereof, and the middle case 200 is provided with a second protruding structure 250 matching with the second bent wall structure 132.

The matching of the first bending wall structure 122 and the first protrusion structure 240 and the matching of the second bending wall structure 132 and the second protrusion structure 250 respectively limit the first step structure 121 from being separated from the first card 210 and the second step structure 131 from being separated from the second card 220, so that the upper casing 30 is stably fixed on the middle casing 200. The first and second

bent wall structures

122 and 132 can also enhance the strength of the first and second sidewalls 120 and 13.

In one embodiment, the first protrusion 240 is provided at a middle position of the middle case 200 in the thickness direction or at a bottom position of the middle case 200 away from the upper case 30 in the thickness direction;

the second projection structure 250 is provided at a middle position of the middle case 200 in the thickness direction or at a bottom position of the middle case 200 distant from the upper case 30 in the thickness direction.

In the initial alignment process of the upper housing 30 and the middle housing 200, if the first protruding structures 240 and the second protruding structures 250 are closer to the top of the middle housing 200, the initial alignment process may be hindered; in the present embodiment, the first protruding structure 240 and the second protruding structure 250 are disposed at the middle position of the middle shell 200 in the thickness direction, so that only after the upper shell 30 is initially located in the middle shell 200, the first bent wall structure 122 is limited by the first protruding structure 240, and the second bent wall structure 132 is limited by the second protruding structure 250.

In one embodiment, the first step structure 121 comprises two first steps and the second step structure 131 comprises two second steps, wherein the first steps comprise intersecting first step transverse walls and first step vertical walls, and the second steps comprise intersecting second step transverse walls and second step vertical walls.

If the first step structure 121 and the second step structure 131 include more than two layers of step structures, although the alignment process can be more smooth, the complexity of the structure is increased, which is not favorable for production and processing. In this embodiment, the first step structure 121 includes only two layers of the first steps and the second step structure 131 includes only two layers of the second steps, so that the first step structure 121 and the second step structure 131 can better guide the upper housing 30 to be located in the middle case 200, and the structures of the corresponding first locking plate 210 and the second locking plate 220 are simpler.

In this embodiment, the first step lateral wall and the second step lateral wall respectively extend along the length direction of the first side wall 120 and the second side wall 130, and the first step vertical wall and the second step vertical wall respectively extend along the height direction of the first side wall 120 and the second side wall 130.

In one embodiment, the first and second step lateral walls each have a slope that slopes toward the top plate 110.

With respect to the first step transverse wall and the second step transverse wall both being parallel to the top plate 110, in the present embodiment, both the first step transverse wall and the second step transverse wall have slopes inclined toward the top plate 110; correspondingly, the matching surfaces of the first card 210 and the second card 220 have the same slope. The provision of the above-mentioned slope facilitates the relative sliding between the upper case 30 and the middle case 200 to be guided into position during the process of mounting the upper case 30 to the middle case 200.

In one embodiment, the first step vertical wall is disposed at an obtuse angle to the first step transverse wall, and the second step vertical wall is disposed at an obtuse angle to the second step transverse wall.

That is, neither the first stepped vertical wall nor the second stepped vertical wall is perpendicular to the top plate 110, but has a slope guiding the upper case 30 into the middle case 200.

In this embodiment, a cleaning machine includes the above-mentioned cleaning machine casing joint structure.

In the cleaning machine with the above-mentioned cleaning machine shell clamping structure, the matching of the first step structure 121 and the first clamping plate 210 and the matching of the second step structure 131 and the second clamping plate 220 form a similar meshing state in the alignment process of the upper shell 30 and the middle shell 200, so as to play a positive guiding and positioning role; and the first card 210 effectively supports the first sidewall 120 and the second card 220 effectively supports the second sidewall 130.
