[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] Reference Figure 1 , Figure 2 and Figure 3 In the first aspect, the utility model proposes a rotating assembly, which is used to drive the snow throwing barrel of the snow removal device to rotate. The snow removal device can be applied to a snow sweeping robot to clear snow on the road or snow in the courtyard. In the following embodiments, the application of the snow removal device to the snow sweeping robot is mainly used as an example for description and introduction, and other situations requiring a snow removal device can be implemented as a reference. The rotating assembly includes an annular fixing member 10 and a rotating kit 20, and the rotating kit 20 is sleeved with the annular fixing member 10, and a ball 30 is embedded between the annular fixing member 10 and the rotating kit 20, so that the rotating kit 20 can rotate relative to the annular fixing member 10.

[0037] Specifically, the annular fixing member 10 is fixed to the inner shell of the snow removal device, and the annular fixing member 10 is arranged around the snow outlet, and the snow throwing cylinder is arranged corresponding to the snow outlet and is located above the snow outlet. The snow removal device generally includes an impeller assembly, and the impeller assembly includes a plurality of centrifugal impellers, and the centrifugal impellers include a plurality of snow sweeping blades. The impeller assembly is installed at the bottom of the snow removal device, and the impeller assembly directly contacts the accumulated snow. When the centrifugal impeller rotates at a high speed, the accumulated snow rolled up by the centrifugal impeller is collected into the snow collection space under the action of centrifugal force, and the accumulated snow is thrown out from the snow outlet, and finally thrown to the designated position through the snow throwing cylinder.

[0038] The rotating kit 20 is connected to the snow throwing cylinder, and the snow throwing cylinder is driven to rotate by the rotation of the rotating kit 20 to change the snow throwing direction as needed. Conventional snow removal devices usually use bearings to enable the rotating assembly to rotate in a stable manner while reducing friction and wear. However, when using bearings, the annular fixing member 10 is usually assembled from multiple parts, which not only increases the installation steps of the rotating assembly, but also increases the cost of the rotating assembly. In this embodiment, the rotating kit 20 is sleeved with the annular fixing member 10, and the two can slide relative to each other. At the same time, a ball 30 is arranged between the rotating kit 20 and the annular fixing member 10. The rolling of the ball 30 can reduce the friction and wear between the rotating kit 20 and the annular fixing member 10 and can reduce the cost of the bearing assembly. In addition, the annular fixing member 10 can adopt a split structure or an integrally formed structure, which can reduce the parts to be assembled, thereby reducing the assembly steps, assembly complexity and assembly time of the rotating assembly.

[0039] In some embodiments, the annular fixing member 10 includes a connecting block 11, the connecting block 11 has a first connecting surface 111, and the first connecting surface 111 has a first receiving groove 112; the rotating sleeve 20 has a second connecting surface, and the second connecting surface has a second receiving groove; the first connecting surface 111 is arranged opposite to the second connecting surface and has a gap, and the first receiving groove 112 is arranged opposite to the notch of the second receiving groove to form a receiving cavity, and the ball 30 is arranged in the receiving cavity.

[0040] Specifically, the annular fixing member 10 has a connecting block 11 for mounting the ball 30, and a first receiving groove 112 for receiving the ball 30 is provided on a first connecting surface 111 of the connecting block 11. The shape of the first receiving groove 112 can be a hemispherical shape adapted to the shape of the ball 30, or a curved ring shape surrounding the rotating shaft, and the first receiving groove 112 can at least receive part of the ball 30. The second connecting surface of the rotating sleeve 20 is arranged opposite to the first connecting surface 111, and a second receiving groove is provided on the second connecting surface. The shape of the second receiving groove is the same as that of the first receiving groove 112, and the second receiving groove can at least receive part of the ball 30. The two receiving grooves are also arranged opposite to each other, so that the two receiving grooves are combined to form a receiving cavity, which is used to receive the ball 30. During the rotation of the rotating set 20, the ball 30 can roll in the receiving cavity, and there is a gap between the first connecting surface 111 and the second connecting surface, that is, when the upper and lower vertices of the ball 30 are respectively against the bottom of the first receiving groove 112 and the second receiving groove, there is a gap between the first connecting surface 111 and the second connecting surface. It should be noted that the gap does not mechanically refer to the distance between the two connecting surfaces. The gap in this embodiment refers to the space not occupied by parts, such as an air gap, a gap filled with grease or lubricating oil, etc. This makes the friction and wear of the rotation between the rotating set 20 and the annular fixing member 10 smaller, and the rotation between the two is smoother.

[0041] In some embodiments, the first connection surface 111 and the second connection surface are both perpendicular to the rotation axis of the rotating component.

[0042] Specifically, since the rotating assembly is sleeved on the annular fixing member 10, the first connecting surface 111 and the second connecting surface are arranged to be parallel to each other and perpendicular to the rotating axis of the transmission assembly, which can make the installation of the rotating assembly more convenient.

[0043] In some embodiments, low-temperature resistant grease is coated between the first connection surface 111 and the second connection surface, and low-temperature resistant grease is coated inside the accommodating cavity.

[0044] Specifically, the low-temperature resistant grease has a low freezing point. The low-temperature resistant grease can maintain fluidity and provide good lubrication performance at low temperatures. Applying the high-temperature resistant grease around the ball 30 can reduce friction and wear, extend the service life of the ball 30, prevent the ball 30 from being damaged due to the solidification of the grease, and ensure the normal rotation of the ball 30 in an extremely cold environment. On the other hand, the low-temperature resistant grease also has good anti-corrosion properties and can protect the metal surface from being corroded by low temperatures and humid environments. In addition, the low-temperature resistant grease can also block the water vapor that may enter the gap between the annular fixing member 10 and the rotating kit 20 from entering the ball 30, preventing the ball 30 from being unable to roll due to the freezing of water vapor.

[0045] In some embodiments, the first connecting surface 111 includes a first plane 1111 and a second plane 1112; the rotating kit 20 includes a transmission gear 21 and a first connecting member 22 connected to the transmission gear 21, and the second connecting surface includes a third plane 211 arranged on the first connecting member 22 and a fourth plane 221 arranged on the transmission gear 21; the first plane 1111 is arranged opposite to the third plane 211, and the second plane 1112 is arranged opposite to the fourth plane 221; there is a first gap 41 between the first plane 1111 and the third plane 211; there is a second gap 42 between the second plane 1112 and the fourth plane 221.

[0046] Specifically, at least two groups of balls 30 are used in this embodiment to realize the rotation of the rotating assembly 20. The outer contour of the transmission gear 21 is roughly annular and is arranged around the snow outlet. The transmission gear 21 is coaxially connected to the first connecting member 22 snow throwing barrel, for example: the transmission gear 21 can be screwed, riveted or welded to the first connecting member 22. The transmission gear 21 is used to be drivably connected to the motor, and the first connecting member 22 can be connected between the snow throwing barrel and the transmission gear 21, so that the rotating assembly can drive the snow throwing barrel to rotate. The first plane 1111 of the first connecting surface 111 is arranged opposite to the third plane 211 on the first connecting member 22 and has a first gap 41, and the first plane 1111 and the third plane 211 The second plane 1112 of the first connecting surface 111 is arranged opposite to the fourth plane 221 on the transmission gear 21 and has a second gap 42. The use of two groups of balls 30 structures to rotate the rotating assembly 20 relative to the annular fixing member 10 can further reduce friction and wear during rotation. The first gap 41 and the second gap 42 are coated with low-temperature resistant grease, which can further reduce friction and wear during rotation.

[0047] In some embodiments, the first accommodating groove includes a first annular accommodating groove disposed on the first plane 1111 and a second annular accommodating groove disposed on the second plane 1112, and the second accommodating groove includes a third annular accommodating groove disposed on the third plane 211 and a fourth annular accommodating groove disposed on the fourth plane 221; the accommodating cavity includes a first annular accommodating cavity and a second annular accommodating cavity; the first annular accommodating groove and the third annular accommodating groove are disposed opposite to each other to form a first annular accommodating cavity; the second annular accommodating groove and the fourth annular accommodating groove are disposed opposite to each other to form a second annular accommodating cavity.

[0048] Specifically, the first receiving groove and the second receiving groove are both annular receiving grooves, and the first receiving groove includes a first annular receiving groove and a second annular receiving groove, the first annular receiving groove is opened on the first plane 1111, and the second annular receiving groove is opened on the second plane 1112. The second receiving groove includes a third annular receiving groove and a fourth annular receiving groove, the third annular receiving groove is opened on the third plane 211, and the fourth annular receiving groove is opened on the fourth plane 221. In this way, since the first plane 1111 is arranged opposite to the third plane 211, and the second plane 1112 is arranged opposite to the fourth plane 221, the openings of the first annular receiving groove and the third annular receiving groove are opposite to each other, forming a first annular receiving cavity, and the openings of the second annular receiving groove and the fourth annular receiving groove are opposite to each other, forming a second annular receiving cavity. The design of the receiving cavity as an annular cavity allows the ball 30 to rotate around the rotation axis in the annular receiving cavity, which can further reduce the friction and wear of the rotation.

[0049] In some embodiments, a first annular retainer 23 is sandwiched between the first plane 1111 and the third plane 211, and the first annular retainer 23 has a plurality of first limiting holes, and the first limiting holes are located in the first annular accommodating cavity; a second annular retainer 23 is sandwiched between the second plane 1112 and the fourth plane 221, and the second annular retainer 23 has a plurality of second limiting holes, and the second limiting holes are located in the second annular accommodating cavity; the ball 30 is arranged in the first limiting hole and the second limiting hole

[0050] An annular retainer 23 is sandwiched between the first plane 1111 and the third plane 211 , and / or between the second plane 1112 and the fourth plane 221 . The annular retainer 23 is provided with a plurality of limiting holes, and the limiting holes are located in the accommodating cavity.

[0051] Specifically, the annular retainer 23 can be arranged between the first plane 1111 and the third plane 211, or between the second plane 1112 and the third plane 211, or can be arranged at both positions. The annular retainer 23 has a plurality of limiting holes that are adapted to the size of the balls 30, and the balls 30 are accommodated in the limiting holes, so that the balls 30 are spaced from each other during the rolling process, and the balls 30 are prevented from gathering in the accommodating cavity.

[0052] In some embodiments, the rotating kit 20 further includes a second connecting member 24 , which connects the first connecting member 22 and the snow throwing tube; the second connecting member 24 has an annular groove 241 , and the annular fixing member 10 has a flange 12 ; the flange 12 is disposed in the annular groove 241 .

[0053] Specifically, in order to reduce the possibility of snow water that may flow back from the snow throwing cylinder through the annular fixing member 10 and enter the receiving chamber, a second connecting member 24 for connecting with the snow throwing cylinder is further provided above the first connecting member 22, and the second connecting member 24 has an annular groove 241 on the side facing away from the snow throwing cylinder. The annular fixing member 10 has a flange 12 for inserting into the groove. In this way, the inflow path of snow water can be increased, the amount of snow water entering the receiving chamber can be reduced, and snow water can be prevented from accumulating near the receiving chamber and freezing, thereby preventing the phenomenon that the ball 30 cannot roll due to the freezing of water vapor.

[0054] In some embodiments, a sealing gasket 50 is disposed between the transmission gear 21 and the first connecting member 22 .

[0055] Specifically, the connection between the transmission gear 21 and the first connecting member 22 may be close to one of the accommodating cavities, and a sealing gasket 50 is arranged between the transmission gear 21 and the first connecting member 22, which can prevent external water vapor from entering between the second plane 1112 and the fourth plane 221 and the inside of the accommodating cavity, and increase the connection resistance between the transmission gear 21 and the first connecting member 22. The material of the sealing gasket 50 can be silicone.

[0056] In some embodiments, the annular fixing member 10 is integrally formed.

[0057] Specifically, the annular fixing member 10 can be prepared in an integrated manner without the need for separation. Compared with the need to make at least two annular members, only one annular fixing member 10 is needed, which reduces the number of parts required for assembling the rotating assembly, reduces production costs, and reduces assembly steps, assembly complexity, and assembly time. In addition, by integrating multiple components into a single component, integrated molding can improve the overall structural strength of the product.

[0058] In a second aspect, the utility model further provides a snow removal device, comprising a rotating assembly according to any one of the above embodiments.

[0059] In a third aspect, the utility model further provides a snow-clearing robot, comprising the snow-removing device provided in the second aspect.

[0060] The above implementation modes are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned implementation modes, a person skilled in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some of the technical features can be replaced by equivalents.
