[0040] Exemplary embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be limited by the embodiments shown here. Rather, these embodiments are intended to provide a more comprehensive understanding of this disclosure and will fully convey its scope to those skilled in the art.

[0041] It should be noted that in traditional technologies, a cover plate for covering or opening a roller brush installation tray is often fitted to the roller brush of a cleaning robot to ensure reliable installation and ease of maintenance of the roller brush, and the cover plate and the machine body are usually joined by means of a locking mechanism. However, the locking mechanism in traditional technologies is more complex; for example, the locking mechanism mentioned above has two or more clamping hooks, and each clamping hook has a corresponding transmission mechanism and operating elements. For this reason, not only is the number of components significant, but the structural compactness of the cleaning robot and the lifting of the roller brush installation tray are also easily limited.Furthermore, a user must operate the aforementioned operating elements simultaneously or one by one during operation, resulting in relatively poor ease of use. At the same time, these operating elements often extend across the width of a guardrail opening in the cover plate. Therefore, if the overall size of the cover plate is limited, the widths of both the guardrail opening and the aforementioned installation tray are easily affected, hindering the effectiveness of the roller brush cleaning operation.

[0042] As shown in Figures 1 to 5, according to a first aspect of the embodiments of the present disclosure, a roller brush cover is proposed. 100 configured to be detachably connected to a roller brush support 200 of a cleaning robot. The roller brush cover 100 comprises a cover body portion 110 provided with an avoidance opening 1101; a transmission portion 120 arranged movably on the cover body portion 110, where at least one end of the transmission portion 120 along the length of the avoidance opening 1101 is an operational end 1201; and a locking portion 130 arranged on the transmission portion 120, where the transmission portion 120 is configured to drive the movement of the locking portion 130.

[0043] The roller brush cover 100 according to the embodiment of this disclosure can be used as a component of the cleaning robot for practical applications. For example, the roller brush cover 100 is detachably connected to the roller brush holder 200 of the cleaning robot. It should be understood that when the roller brush cover 100 is mounted on the roller brush holder 200, the roller brush cover 100 and the roller brush holder 200 together form a recess for installing the roller brush body 300. When the roller brush cover 100 is detached from the roller brush holder 200, the recess is open, which is convenient for the user to perform maintenance and replacement of the roller brush body 300.When the roller brush cover 100 is fitted onto the roller brush support 200, the installation reliability and stability of the roller brush body 300 can be guaranteed, which is beneficial for the roller brush body 300 to perform cleaning actions stably during a cleaning operation process.

[0044] As shown in Figures 1 and 2, the roller brush cover 100 according to the embodiment of this disclosure comprises the cover body portion 110, the transmission portion 120, and the locking portions 130, wherein the cover body portion 110 is provided with the bypass opening 1101. In practical applications, the bypass opening 1101 can be arranged to correspond with the roller brush body 300, in order to reduce the obstruction of the cover body portion 110 for the roller brush body 300 and to facilitate the passage of the roller brush body 300 through and cleaning an object to be cleaned. The transmission portion 120 is arranged on the cover body portion 110 and can move relative to the cover body portion 110.In practical applications, the operational end 1201 of the transmission part 120 can be configured to receive power, which is convenient for the transmission part 120 to move relative to the cover body part. 110 with the aforementioned power drive, thus facilitating the user's movement of the transmission part 120 by touching the operational end 1201. The locking parts 130 are arranged on the transmission part 120, so that the transmission part 120 can drive the locking parts 130 during movement. In practical applications, the locking parts 130 can be configured to be paired with the aforementioned roller brush support 200 to enable the removal and installation of the roller brush cover 100. The aforementioned transmission part 120 can move relative to the cover body part 110 between a first and a second position.When the transmission part 120 is in the first position, the locking parts 130 can be fitted and locked with the roller brush support 200, so that the roller brush cover 100 can be fixedly connected to the roller brush support 200, ensuring the installation reliability and stability of the roller brush body 300. When the transmission part 120 is in the second position, the locking relationship between the locking parts 130 and the roller brush support 200 is released, allowing the roller brush cover 100 to be separated from the roller brush support 200 in order to open the aforementioned installation tray, which is convenient for the user to perform maintenance and replacement of the roller brush body 300.

[0045] At the same time, in practical applications, the width direction of the avoidance opening 1101 can be configured to correspond to a radial direction of the roller brush body 300, and consequently, the length direction of the avoidance opening 1101 can be configured to correspond to an axial direction of the roller brush body.Compared to the traditional technologies mentioned above, the roller brush cover 100 according to the embodiment of this disclosure can save the space of the roller brush cover 100 in the width direction of the avoidance opening 1101, provided that the width of the roller brush cover 100 is limited by arranging at least one end of the transmission part 120 in the length direction of the avoidance opening 1101 as the operational end 1201, which is beneficial for increasing the widths of the avoidance opening 1101 and the installation cavity mentioned above and for providing more adequate radial space for the roller brush body 300, thus facilitating the fact that the roller brush body 300 performs the cleaning actions, increasing a contact area between the roller brush body 300 and the object to be cleaned and improving a sweeping effect.

[0046] It should be understood that the roller brush support 200 mentioned above can be provided with corresponding parts adapted to the locking parts 130 mentioned above. The locking parts 130 are configured to be locked in place with the corresponding parts mentioned above when the transmission part 120 is in the first position, and disengaged from the corresponding parts mentioned above when the transmission part 120 is in the second position. The number of corresponding parts mentioned above can be at least two, and the locking parts 130 correspond one-to-one with the corresponding parts.

[0047] It must be understood that at least one end of the transmission portion 120 along the length of the avoidance opening 1101 is the operational end 1201, which means that one end of the transmission portion 120 along the length of the avoidance opening 1101 can be arranged as the operational end 1201 and the other end can be a non-operational end, or both ends of the transmission portion 120 along the length of the avoidance opening 1101 can be arranged as operational ends 1201. The number of operational ends 1201 can be determined in combination with the actual requirements, which is not excessively limited here.

[0048] As shown in Figures 3 to 5, in some embodiments the number of locking parts 130 is at least two, the respective locking parts 130 are arranged on the same transmission part 120, and the transmission part 120 is configured to drive the synchronous movement of the respective locking parts 130.

[0049] In this technical solution, the number of locking parts 130 mentioned above is at least two, so that in practical applications, the roller brush cover 100 and the roller brush support 200 can be matched appropriately in a plurality of positions, which is beneficial for improving the reliability of the connection between the roller brush cover 100 and the roller brush support 200 and reducing the risk of the roller brush cover 100 falling off.Furthermore, the respective locking parts 130 mentioned above can be driven by the same transmission part 110 to move synchronously, so that the respective locking parts 130 can be in adjustment with locking with or disengaged from the roller brush support 200 at the same time, which can reduce the number of mechanisms to drive the movement of the locking parts 130, improve the convenience of dismantling and mounting operations of the roller brush cover 100 and reduce the structural volume of the roller brush cover 100, thus being beneficial. to increase the volume of the installation cavity mentioned above, convenient for the 300 roller brush body to perform cleaning actions, and improving the cleaning performance of the cleaning robot.

[0050] Compared to the conventional technologies mentioned above, based on the arrangement mentioned above, the roller brush cover 100 according to the embodiment of this disclosure can ensure that the roller brush cover 100 and the roller brush support 200 can be adjusted with locking in a plurality of positions, while the respective locking parts 130 are driven to act synchronously using the same transmission part 120, which can reduce the number of mechanisms to drive the movement of the locking parts 130, improve the convenience of disassembly and assembly operations of the roller brush cover 100 and reduce the structural volume of the roller brush cover 100, thus being beneficial for increasing the volume of the installation cavity mentioned above, convenient for the roller brush body 300 to perform cleaning operations,and improving the cleaning performance of the cleaning robot.

[0051] It must be understood that the at least two locking parts 130 mentioned above can be arranged at intervals on the transmission part 120, so that the difference in position among the respective locking parts 130 can be improved to further enhance the corresponding position diversity between the roller brush cover 100 and the roller brush support 200, which is beneficial for improving the reliability of the connection between the roller brush cover 100 and the roller brush support 200 and reducing the risk of the roller brush cover 100 falling off.

[0052] It must be understood that the number of locking parts 130 mentioned above can be greater than or equal to two, for example, two, three, four, five or six, etc., and the specific number can be selected in combination with the actual requirements, which is not excessively limited here.

[0053] As shown in Figures 2 and 4, in some embodiments, the transmission part 120 comprises: a transmission element 121 arranged movably on the cover body part 110, where the transmission element 121 causes the locking parts 130 to move in a first direction; a return element 122 connected between the cover body part 110 and the transmission element 121, where the return element 122 is configured to exert an action force on the transmission element 121 in a second direction opposite to the first direction; and a pressure element 123 arranged at one end of the transmission element 121.

[0054] In this technical solution, the transmission part 120 mentioned above may include the transmission element 121, the return elements 122 and the pressure element 123, in which the transmission element 121 is movably connected with the cover body part 110 and can move between the first position mentioned above and the second position mentioned above, and consequently, the transmission element 121 can cause the synchronous movement of the respective locking parts 130 in the first direction during the movement process.The pressure element 123 mentioned above is arranged at one end of the transmission element 121 and has the operational end 1201 mentioned above, so that the transmission part 120 can receive power through the pressure element 123 and transmit power to the locking parts through the transmission element 121, and the position of the locking parts changes under the action of the power mentioned above, which can further improve the convenience of operation of the transmission part 120 in practical applications.The return elements 122 mentioned above are connected between the cover body part 110 and the transmission element 121, and are configured to exert a force on the transmission element 121 in a direction from the second position to the first position, that is, to exert a force on the transmission element 121 in the second direction opposite to the first direction. Therefore, if the pressure element 123 does not receive an external power supply, the transmission element 121 can be held in the first position by the force exerted by the return elements 122, thus maintaining the locking adjustment relationship between the locking parts 130 and the roller brush support 200.Furthermore, the reliability of the connection between the roller brush cover 100 and the roller brush support 200 is guaranteed, and the risk of the roller brush cover falling off is reduced. When the pressure element 123 receives external power, if the aforementioned external power can overcome the action force of the return elements 122, the transmission part 120 can move from the first position to the second position. This allows the locking parts 130 to release the locking mechanism of the roller brush support 200, and then the roller brush cover 100 and the roller brush support 200 can be separated. This facilitates access to the aforementioned installation cavity and improves the ease of maintenance and replacement of the roller brush body 300.

[0055] It must be understood that the return elements 122 mentioned above are configured to exert the action force on the transmission element 121 in the second direction opposite to the first direction, which means that the force The force exerted by the return elements 122 on the transmission element 121 has a component in the second direction, such that the force exerted by the return elements 122 on the transmission element 121 can cause the transmission element 121 to move from the second position to the first position or remain in the first position. Considering the effectiveness of the force exerted by the return elements 122, it can be determined that a component of the force exerted by the return elements 122 on the transmission element 121 in the second direction can be greater than or equal to a component of the force exerted in a direction orthogonal to the direction mentioned above.

[0056] It should be understood that the return element 122 mentioned above may include an elastic element, such as a spring, and a stiffness coefficient of the elastic element may be selected in combination with the actual requirements, which is not excessively limited here.

[0057] In some feasible embodiments, the transmission element 121 mentioned above may be a transmission shaft, so that the transmission element 121 may have a relatively simple shape and configuration, which is convenient for the assembly of the transmission element 121 and beneficial for improving the structural compactness of the transmission element 121, thereby improving a space utilization rate of the roller brush cover 100.

[0058] As shown in Figures 2 and 4, in some embodiments, the locking parts 130 and the transmission element 121 have an integrated structure.

[0059] In this technical solution, the locking parts 130 and the transmission element 121 can be an integrated structure. Therefore, on the one hand, the reliability of the connection between the locking parts 130 and the transmission element 121 can be improved, and the relative movement between the locking parts 130 and the transmission element 121 is avoided, which is beneficial for improving the transmission effect between the transmission element 121 and the locking parts 130, and ensuring a stable and reliable connection between the locking parts 130 and the roller brush support 200.On the other hand, during the manufacturing process of the roller brush cover 100, the locking parts 130 and the transmission element 121 can also be manufactured by integral molding, which is beneficial for reducing the difficulty of assembly between the locking parts 130 and the transmission element 121 and reducing the manufacturing cost of the roller brush cover 100.

[0060] In certain feasible embodiments, the locking parts 130 and the transmission element 121 may both be made from a plastic material, for example, may both be made from acrylonitrile butadiene styrene (ABS) material, so that the locking parts 130 and the transmission element 121 can have a relatively light mass, while ensuring the structural reliability of the locking parts 130 and the transmission element 121, which is beneficial for improving the lightness level of the roller brush cover 100, avoiding excessive hardness of the locking parts 130 and reducing the risk of damaging the roller brush support 200 during a matching process.

[0061] In some embodiments, the transmission element 121 is provided with anti-slip lines, and the locking parts 130 are arranged on the anti-slip lines.

[0062] In this technical solution, the transmission element 121 and the locking parts 130 can have a divided structure. Therefore, the surface of the transmission element 121 can be provided with anti-slip lines, and the locking parts 130 can be arranged on the anti-slip lines. Consequently, based on the arrangement mentioned above, during the manufacturing process of the transmission element 121 and the locking parts 130, suitable manufacturing materials are selected in combination with the respective working characteristics of the transmission element 121 and the locking parts 130. This is beneficial for extending the service life of the transmission element 121 and the locking parts 130 and improving the structural reliability of the transmission element 121 and the locking parts 130.On the other hand, the reliability of the connection between the transmission element 121 and the locking parts 130 can be improved, and the risk of relative movement between the locking parts 130 and the transmission element 121 is reduced, which is beneficial for improving the transmission effect between the transmission element 121 and the locking parts 130, and ensuring the stable and reliable correspondence between the locking parts 130 and the roller brush support 200.

[0063] By way of example, in the condition where the transmission element 121 is the transmission shaft mentioned above, the aforementioned anti-slip lines can be formed on the circumferential side of the transmission shaft. Therefore, the locking parts 130 can be provided with connecting holes, and the connecting holes are fitted at the level of the anti-slip lines. It should be understood that the aforementioned anti-slip lines can be formed by an embossing process, but are not limited to this.

[0064] In certain feasible embodiments, the transmission element 121 mentioned above may be made from a metallic material, and the locking parts 130 mentioned above may be made from a plastic material. For example, the transmission element 121 mentioned above may be made from SUS 304 stainless steel and the 130 locking parts mentioned above can be made from ABS.

[0065] As shown in Figures 2 and 4, in some embodiments, the number of return elements 122 mentioned above is at least two, at least one return element 122 is arranged between one end of the transmission part 120 opposite the pressure element 123 and the cover body part 100, and at least one return element 122 is arranged between the pressure element 123 and the cover body part 110.

[0066] In this technical solution, the number of return elements 122 mentioned above can be at least two, at least one return element 122 is arranged between one end of the transmission part 120 opposite the pressure element 123 and the cover body part 110, and at least one return element 122 is arranged between the pressure element 123 and the cover body part 110. Based on the arrangement mentioned above, both ends of the transmission element 121 can be influenced by the action force of the return elements 122.In addition, the adjustment relationship with locking is maintained more reliably between the locking parts 130 and the roller brush support 200, and the efficiency and stability of the return of the transmission part 120, from the second position to the first position, are improved, which is beneficial for further improving the operational convenience of the roller brush cover 100.

[0067] In some embodiments, the transmission element 121 is made from a metallic material or a plastic material.

[0068] In this technical solution, the transmission element 121 can be made with a metallic material, so that the structural strength of the transmission element 121 can be improved, the service life of the transmission element 121 can be extended, and the probability of deformation of the transmission element 121 can be reduced, which is beneficial for ensuring the displacement stability of the transmission element 121.

[0069] Alternatively, the transmission element 121 can be made of a plastic material, so that the transmission element 121 can simultaneously have better structural reliability and a lighter mass, which is beneficial for improving the lightness level of the roller brush cover 100 and reducing resistance when the user operates the transmission part 120.

[0070] It should be understood that the metallic material mentioned above can be stainless steel, carbon steel and other metallic materials, and for example, can be SUS 304 stainless steel, without being limited to it.

[0071] It should be understood that the plastic material mentioned above may be ABS, polypropylene and other plastic materials, without being limited to them.

[0072] As shown in Figures 1, 2 and 4, in some embodiments, the cover body portion 110 comprises a first cover plate 111 provided with the avoidance opening 1101; and a second cover plate 112 arranged on the first cover plate 111, where an installation space 1102 is defined between the first cover plate 111 and the second cover plate 112. One end of the transmission portion 120 opposite the operational end 1201 is located in the installation space 1102, and the operational end 1201 is located outside the installation space 1102.

[0073] In this technical solution, the cover body part 110 mentioned above may include the first cover plate 111 and the second cover plate 112, in which the avoidance opening 1101 mentioned above is formed in the first cover plate 111 mentioned above, the second cover plate 112 mentioned above and the first cover plate 111 defining the installation space 1102, and the installation space 1102 can be configured to install the transmission part 120 mentioned above, thus reducing a degree of exposure of the transmission part 120 and being beneficial to reduce the risk of damage to the transmission part 120.In practical applications, one end of the transmission part 120 opposite the operational end 1201 may be located in the installation space 1102, and the operational end 1201 is located outside the installation space 1102, so that the transmission part 120 can be protected by the cover body part 110, and at the same time the operational end 1201 receives external power in an appropriate manner, which is beneficial to ensure the convenient operation of the transmission part 120.

[0074] It should be understood that the first cover plate 111 and the second cover plate 112 can be provided respectively with first limiting elements 1111 and second limiting elements 1121. The first limiting elements 1111 are configured to correspond with the second limiting elements 1121 in order to limit the degree of freedom of the transmission part 120 and prevent the transmission part 120 from being significantly deformed, which is beneficial for ensuring the displacement stability and structural reliability of the transmission part 120. By way of example, in the condition in which the transmission part 120 includes the transmission shaft mentioned above, the first limiting elements 1111 mentioned above and the second limiting elements 1121 mentioned above can be provided respectively with adapted semi-circular notches.The semi-circular notch of the first limiting element 111 can be connected with the semi-circular notch of the second limiting element 1121 to form a circular hole and the transmission shaft. The aforementioned drive shaft enters the circular hole in a movable manner. There are a plurality of first limiting elements 1111 and a plurality of second limiting elements 1121, which correspond one to one.
