The cleaning turntable mainly consists of a disk base and a connecting disk, and a cleaning rag is fixed on the connecting disk. Considering that the rag needs to be replaced or cleaned regularly, a detachable connection structure is adopted between the disk base and the connecting disk. At present, a snap connection method is generally adopted between the disk base and the connecting disk. Specifically, a plurality of snaps are provided on the disk base, and a corresponding plurality of slots are provided on the connecting disk. Although this kind of structure is relatively convenient for disassembly and assembly, each snap and slot must be aligned with each other to achieve snap fit, which undoubtedly increases the assembly difficulty and affects the assembly efficiency. Summary of the Utility Model

[0003] One of the purposes of the utility model is to provide a turntable assembly that is more convenient for assembly.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: a turntable assembly that is convenient for assembly, including a disk base and a connecting disk that are detachably connected through a snap connection structure.

[0029] In order to enable those skilled in the art to more clearly understand the concept of the present invention, the following further describes it in conjunction with embodiments and drawings.

[0030] Such as Figure 1As shown in the figure, the cleaning robot of this embodiment includes a cleaning turntable 1, a suction module 2, a driving module 3, a controller 4, and a body 5. The cleaning turntable 1 is generally disc-shaped. According to needs, the number of cleaning turntables 1 can be one or more. The cleaning turntable 1 is located at the bottom of the body 5 and is driven to rotate by the driving module 3 to clean the surface to be cleaned. The aforementioned surface to be cleaned includes, but is not limited to, the surface of a plate member (such as a floor, a vertical glass window, a glass curtain wall, etc.). The above suction module 2 includes, but is not limited to, a negative pressure fan or a vacuum pump. In addition, since the air duct, walking mode, and control circuit of the cleaning robot involved in this embodiment are similar to those of existing cleaning robots, for the purpose of simplifying the description, the above content will not be elaborated further.

[0031] Similar to existing cleaning robots, the cleaning turntable 1 of this embodiment also adopts a detachable connection structure, which is convenient for users to replace or clean the rag. As Figure 2-9 shown, the cleaning turntable 1 (equivalent to the turntable assembly) is composed of a circular disk base 1a and a connecting disk 1b. The disk base 1a is connected to the body 5, and a rag for cleaning is fixed on the connecting disk 1b. The disk base 1a and the connecting disk 1b are also detachably connected through a snap connection structure, and the disk base 1a and the connecting disk 1b are assembled together up and down. Different from the prior art, the snap connection structure in this embodiment is configured to allow the disk base 1a and the connecting disk 1b to be assembled and connected at any position along the circumference, which reduces the time required for alignment and fixation, thereby improving the assembly efficiency. The snap connection structure mainly includes an annular or circular snap groove hole 1b2 (such as a circular through hole) and an annular snap or a plurality of arc-shaped snaps 1a3 distributed at intervals along the circumference. They cooperate with each other and are respectively arranged on two opposite end faces between the disk base 1a and the connecting disk 1b. Of course, the positions of the snap and the snap groove hole 1b2 can be interchanged. During the assembly process, due to the structural characteristics, the annular or circular snap groove hole 1b2 allows the annular snap or the arc-shaped snap 1a3 before snapping to rotate therein, so that the annular snap or the arc-shaped snap 1a3 can be preliminarily assembled at any position along the circumference of the annular or circular snap groove hole 1b2, thus realizing quick connection. This connection method not only improves the assembly efficiency but also enables users to easily disassemble and reassemble the turntable assembly.

[0032] To further improve the convenience and accuracy of assembly, an engaging and positioning mechanism is provided between the disk base 1a and the connecting disk 1b in this embodiment, which can play a role of quick positioning during the assembly process. The engaging and positioning mechanism includes a plurality of positioning groove holes 1b1 evenly distributed at intervals along the circumference, and at least one positioning protrusion 1a1 corresponding to the positioning groove holes 1b1. These positioning elements are respectively arranged on the disk base 1a and the connecting disk 1b (the positions can be interchanged), providing multiple alignment points for assembly, increasing flexibility, ensuring the accuracy and diversity of assembly, while simplifying the operation process and reducing the operation difficulty.

[0033] In this embodiment, the fitting positioning mechanism mainly consists of two parts: one is the positioning slot hole 1b1, and the other is the positioning protrusion 1a1. They are respectively arranged on the disc base 1a and the connecting disc 1b. Among them, the positioning slot holes 1b1 and / or the positioning protrusions 1a1 are configured to be evenly distributed at intervals along the circumference, which can form multiple assembly alignment points, avoid complex alignment operations, and reduce the assembly difficulty. Of course, the positions of the positioning slot holes 1b1 and the positioning protrusions 1a1 can be interchanged. For example, the positioning slot holes 1b1 can be arranged on the disc base 1a or on the connecting disc 1b, and the same is true for the positioning protrusions 1a1. For the sake of easy understanding, the following mainly takes the positioning slot holes 1b1 arranged on the connecting disc 1b and the positioning protrusions 1a1 arranged on the disc base 1a for specific description. Exemplarily, on the connecting disc 1b, a plurality of positioning slot holes 1b1 are evenly distributed at intervals along the circumference, and they are arranged according to the rule of equal angles to facilitate matching with the positioning protrusions 1a1 on the disc base 1a. On the disc base 1a, a plurality of positioning protrusions 1a1 are also evenly distributed at intervals along the circumference to correspond to the positioning slot holes 1b1 on the connecting disc 1b. When the disc base 1a and the connecting disc 1b are assembled, through the mutual fitting of the positioning slot holes 1b1 and the positioning protrusions 1a1, quick and accurate alignment can be achieved. Moreover, due to the uniform distribution of the positioning slot holes 1b1 and the positioning protrusions 1a1, users do not need to perform complex alignment operations, thereby significantly reducing the assembly difficulty and improving the assembly efficiency. In addition, this uniformly distributed positioning mechanism also provides multi-point contact, enhancing the friction and stability between the disc base 1a and the connecting disc 1b, and ensuring the reliability of the turntable assembly during operation.

[0034] For the fitting positioning mechanism, not only can the same number of positioning slot holes 1b1 and positioning protrusions 1a1 be configured, but also different numbers of positioning slot holes 1b1 and positioning protrusions 1a1 can be configured, which can be selected as needed. The following takes the example of different numbers of positioning slot holes 1b1 and positioning protrusions 1a1. As Figure 4 、 7 shown, on the connecting disc 1b, a plurality of positioning slot holes 1b1 are provided, and these positioning slot holes 1b1 are evenly distributed at intervals along the circumference, providing clear reference points for assembly. As Figure 3 、 5 、8, 9 shown, on the disc base 1a, positioning protrusions 1a1 with a number less than that of the positioning slot holes 1b1 are provided, and these positioning protrusions 1a1 are divided into multiple groups, with each group including at least one positioning protrusion 1a1, and these positioning protrusions 1a1 are also distributed along the circumference to cooperate with the positioning slot holes 1b1 on the connecting disc 1b. Since the positioning slot holes 1b1 are evenly distributed at intervals along the circumference, even if the number of positioning protrusions 1a1 is small, users can easily achieve quick alignment, simplifying the assembly process.

[0035] There can be various configurations for the positions of the positioning slot holes 1b1 and the positioning protrusions 1a1, including but not limited to the following several methods. First, the positioning slot holes 1b1 and the positioning protrusions 1a1 are respectively arranged on two opposite end faces between the disk base 1a and the connecting disk 1b. Of course, the positions of the positioning slot holes 1b1 and the positioning protrusions 1a1 can be interchanged. For example, the positioning protrusion 1a1 is arranged on the end face of the disk base 1a, and the positioning slot hole 1b1 is arranged on the end face of the connecting disk 1b. These two end faces are arranged opposite to each other. Refer to Figure 3-5 . Second, in the disk base 1a and the connecting disk 1b, an annular or circular slot hole is arranged on the end face of one of the components, the positioning slot hole 1b1 is opened on the side wall of the annular or circular slot hole, and the positioning protrusion 1a1 is arranged on the corresponding end face of the other component. For example, a circular slot hole is arranged on the end face of the connecting disk 1b, the positioning slot hole 1b1 is opened on the side wall of the circular slot hole, and the positioning protrusion 1a1 is arranged on the end face of the disk base 1a. These two end faces are arranged opposite to each other. Third, annular protrusions or arc-shaped protrusions 1a2 (the number is one or multiple spaced along the circumference) and annular or circular slot holes are respectively arranged on two opposite end faces of the disk base 1a and the connecting disk 1b, and the positioning slot holes 1b1 and the positioning protrusions 1a1 are respectively arranged on two opposite side walls between the annular protrusions or arc-shaped protrusions 1a2 and the annular or circular slot holes. Of course, the positions of the positioning slot holes 1b1 and the positioning protrusions 1a1 can be interchanged. For example, a circular slot hole (this circular slot hole is a through hole and can also be used as the snap slot hole 1b2) is arranged on the end face of the connecting disk 1b, and multiple arc-shaped protrusions 1a2 spaced along the circumference that can be inserted into the circular slot hole are arranged on the corresponding end face of the disk base 1a. The positioning slot holes 1b1 and the positioning protrusions 1a1 are respectively arranged on two opposite side walls between the arc-shaped protrusions 1a2 and the circular slot hole. Refer to Figure 7-9 .

[0036] In this embodiment, as Figure 4 、 7 shown, the positioning slot holes 1b1 are evenly spaced along the circumference and are equally angularly distributed. The angle between any two adjacent positioning slot holes 1b1 does not exceed 10 degrees (such as 10 degrees or 8 degrees), that is, the previous positioning slot hole 1b1 rotates an angle of no more than 10 degrees to reach the next positioning slot hole 1b1 to achieve a dense distribution. Among them, the number of the positioning slot holes 1b1 is usually not less than 36, such as 45.

[0037] In addition, in order to facilitate the positioning protrusion 1a1 to be inserted into the positioning slot hole 1b1 more easily and smoothly, chamfers or rounded corners (circular arcs) can be provided on the edges of the positioning protrusion 1a1 and the positioning slot hole 1b1.

[0038] For a snap - connection structure, the extension trajectory of the annular snap or the distribution trajectory of the arc - shaped snap 1a3 can coincide with or be parallel to (or concentric and coaxial with) the distribution trajectory of the positioning slot hole 1b1 or the positioning protrusion 1a1. For example, when the positioning protrusions 1a1 are arranged at annular intervals on the end face of the disk base 1a, and the positioning slot holes 1b1 are arranged at uniform annular intervals on the end face of the connecting disk 1b, these arc - shaped snaps 1a3 are distributed at annular intervals inside the distribution trajectory of the positioning protrusions 1a1 (their trajectories are parallel), as can be seen in Figure 3 , 5 . When a circular slot hole (which is a through - hole and can also be used as a circular snap - lock slot hole 1b2) is provided on the connecting disk 1b, a plurality of arc - shaped protrusions 1a2 are arranged at annular intervals on the disk base 1a, the positioning slot holes 1b1 are arranged at uniform annular intervals on the side wall of the circular slot hole (the positioning slot hole 1b1 is a U - shaped slot that penetrates up and down), and the positioning protrusions 1a1 are arranged at annular intervals on the outer side wall of the arc - shaped protrusions 1a2, these arc - shaped snaps 1a3 are distributed at annular intervals on the distribution trajectory of the positioning protrusions 1a1 (their trajectories coincide). For example, each arc - shaped snap 1a3 and each group of positioning protrusions 1a1 are arranged alternately, as can be seen in 8, 9.

[0039] During the assembly process of the connecting disk 1b and the disk base 1a, the arc - shaped snaps 1a3 are distributed at intervals along an annular path. Each arc - shaped snap 1a3 can fit into and be inserted into the circular snap - lock slot hole 1b2 to achieve preliminary positioning. Subsequently, by moderately pressing the connecting disk 1b, the positioning protrusions 1a1 slide into the corresponding positioning slot holes 1b1 to complete alignment. Considering the possible angular deviation in actual operation, the uniform interval distribution and the number of the positioning slot holes 1b1 ensure that even if the positioning protrusions 1a1 are not initially completely aligned, under the action of a moderate force, the connecting disk 1b can be guided to perform necessary small rotations through the component forces of the force, ensuring that the positioning protrusions 1a1 can smoothly and completely slide into the positioning slot holes 1b1 to reach a stable and precise assembly state.

[0040] The snap - connection structure adopted by the turntable assembly in this embodiment, by setting the snap - lock slot hole 1b2 to be annular or circular, allows the arc - shaped snaps 1a3 before snap - fitting to freely rotate in the snap - lock slot hole 1b2, enabling the disk base 1a and the connecting disk 1b to be quickly and preliminarily assembled at any position along the circumference. Subsequently, the function of the fitting and positioning mechanism ensures the precise positioning between the disk base 1a and the connecting disk 1b. Thus, without sacrificing stability, the time required for alignment and fixation is significantly reduced, improving the overall assembly efficiency. In addition, the above - mentioned solution simplifies the assembly, maintenance, and replacement processes, making user operation more intuitive and easier, while ensuring that the assembled component has the required stability and reliability.

[0041] The above embodiments are preferred implementation solutions of the present utility model. Any obvious substitution without departing from the concept of the technical solution is within the protection scope of the present utility model.
