[0041] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model.

[0043] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps described in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0044] As mentioned in the background technology, the side sweeper of the existing cleaning equipment is easily in contact with wet oil or water stains for a long time, which will affect the service life of the side sweeper, and the contact area between the side sweeper and the blanket is too large, which is not convenient for smooth movement. To this end, the present application provides a new side sweeper lifting device, in which the side sweeper can be lifted and lowered, so that the position of the side sweeper can be adjusted according to the actual use requirements of the cleaning equipment, which can not only improve the service life of the side sweeper in this embodiment, but also facilitate the rotation of the side sweeper to effectively clean the blanket, etc. The side sweeper lifting device of the present application will be described in detail below in conjunction with the accompanying drawings.

[0045] See also Figures 1 to 5 According to an embodiment of the present application, a side-sweeping lifting device is provided, which includes a mounting bracket 10, a side sweeper 20, and a rotating lifting assembly 30.

[0046] Specifically, the side sweeper 20 in this embodiment includes a main body 21 and a cleaning arm 22. The main body 21 is mounted on the mounting bracket 10. The cleaning arm 22 is connected to the outer edge of the main body 21 and extends in a direction away from the main body 21. The cleaning arm 22 extends out of the outer edge of the mounting bracket 10. The cleaning arm 22 has a first position inclined toward the bottom of the mounting bracket 10 (see Figures 1 to 3 ) and a second position tilted toward the top of the mounting bracket 10 (see Figure 4 and Figure 5As shown). It can be understood that the bottom of the mounting bracket 10 mentioned here refers to the side of the mounting bracket 10 facing the cleaned surface (such as the ground or the table) when the side sweeping lifting device is working; correspondingly, the top of the mounting bracket 10 refers to the side of the mounting bracket 10 away from the cleaned surface.

[0047] Further, the rotating lifting assembly 30 includes a rotating component 31 and a lifting component 32, wherein the rotating component 31 is connected to the mounting bracket 10 and is used to drive the mounting bracket 10 to rotate, and the lifting component 32 is disposed between the rotating component 31 and the mounting bracket 10. When the rotating component 31 drives the mounting bracket 10 to rotate in a first direction and a second direction opposite to the first direction, the lifting component 32 can be synchronously driven to move and exert force on the main body 21, and finally the cleaning arm 22 can be driven to switch between the first position and the second position.

[0048] Specifically, when the rotating component 31 rotates along a first direction (the first direction can be either clockwise or counterclockwise), the cleaning arm 22 is in a first position, the cleaning arm 22 is tilted toward the bottom of the mounting bracket 10 and can rotate along the first direction, so as to clean the dirt on the ground or the table top; when the rotating component 31 drives the mounting bracket 10 to rotate in a second direction opposite to the first direction (the second direction can be either counterclockwise or clockwise), the lifting component 32 can be driven to move at the same time to apply force to the main body 21, and then the main body 21 can be used to drive the cleaning arm 22 to move, so that the cleaning arm 22 is switched from the first position to the second position, at which time the cleaning arm 22 is tilted toward the top of the mounting bracket 10, and the cleaning arm 22 can be separated from the ground or the table top.

[0049] That is to say, after the side sweep lifting device in this embodiment is installed in the cleaning device, the corresponding detection and control logic can be set on the cleaning device to control the side sweep lifting device according to the working environment of the cleaning device. In this way, the cleaning arm 22 of the side sweep 20 can be switched between the first position and the second position, which can not only prevent the cleaning arm 22 of the side sweep 20 from being in contact with wet oil stains or water stains for a long time, but also prevent the side sweep 20 from having too large a contact area with the blanket and the like, resulting in an unsmooth movement, and ultimately achieve the purpose of increasing the service life and use stability of the side sweep 20 in this embodiment. In addition, when the cleaning device is crossing an obstacle, the cleaning arm 22 can also be switched to the second position to facilitate the obstacle crossing height of the cleaning device.

[0050] Combination Figures 1 to 6As shown, the rotating component 31 in this embodiment includes a driving mechanism and a rotating bracket 313. Among them, the driving mechanism includes a driving part and a rotating shaft 3121, and the driving part is connected to the rotating shaft 3121 to drive the rotating shaft 3121 to rotate in a first direction or a second direction opposite to the first direction. The mounting bracket 10 is fixedly connected to the rotating shaft 3121; the rotating bracket 313 is rotatably mounted on the driving mechanism through a one-way bearing 40, and the rotation axis of the rotating bracket 313 is consistent with the axis of the rotating shaft 3121. During actual operation, the one-way bearing 40 in this embodiment can rotate in the first direction, but cannot rotate in the second direction. The lifting component 32 is installed between the rotating bracket 313 and the mounting bracket 10. When the rotating shaft 3121 rotates along the first direction, the lifting component 32 rises relative to the mounting bracket 10 and moves away from the main body 21 so that the cleaning arm 22 is in the first position, and at the same time drives the rotating bracket 313 to rotate along the first direction; when the rotating shaft 3121 rotates along the second direction, the lifting component 32 is restricted by the rotating bracket 313 and descends relative to the mounting bracket 10 and presses down the main body 21 so that the cleaning arm 22 switches to the second position.

[0051] Specifically, the driving unit in this embodiment includes a motor 311 and a reduction box 312. The input end of the reduction box 312 is connected to the output shaft of the motor 311, and the output end of the reduction box 312 is provided with the rotating shaft 3121 described above; wherein, the rotating bracket 313 is generally in a ring-shaped structure, and the rotating bracket 313 and the one-way bearing 40 are both installed on the reduction box 312. After installation, the ring-shaped rotating bracket 313 is arranged around the outer periphery of the rotating shaft 3121. When the motor 311 rotates forward and reverse, it can drive the reduction box 312 to work, and then drive the rotating shaft 3121 to rotate in the first direction or the second direction. Finally, the rotating bracket 313, the lifting bracket 321 and the mounting bracket 10 perform corresponding movements to drive the cleaning arm 22 of the side sweeper 20 to switch between the first position and the second position.

[0052] In this embodiment, the reduction box 312 includes a housing component 3122 and a gear assembly 3123. The housing component 3122 is surrounded to form a cavity, and the gear assembly 3123, the one-way bearing 40, the rotating shaft 3121 and the rotating bracket 313 are all installed in the cavity, and the structure is compact and stable. After the reduction box 312 is assembled, the rotating shaft 3121 at least partially extends out of the housing component 3122, which is convenient for connection with the mounting bracket 10, and at least part of the rotating bracket 313 also extends out of the housing component 3122, which is convenient for cooperation with the lifting component 32.

[0053] See also Figure 3As shown, the rotating bracket 313 in this embodiment is provided with a mounting hole 3131 coaxially arranged with the rotating shaft 3121; and the mounting bracket 10 is provided with a mounting cavity 101, an avoidance hole 102 and a connecting column 103. During assembly, the main body 21 is installed in the mounting cavity 101, the avoidance hole 102 is communicated with the mounting cavity 101, and the connecting column 103 passes through the avoidance hole 102 and is fixedly connected with the rotating shaft 3121; the lifting component 32 includes a lifting bracket 321, a first end of the lifting bracket 321 is inserted in the avoidance hole 102 and contacts with the main body 21, and a second end of the lifting bracket 321 opposite to the first end is inserted in the mounting hole 3131. Among them, when the rotating shaft 3121 rotates along the first direction, the lifting bracket 321 rises relative to the connecting column 103 and moves away from the main body 21 to make the cleaning arm 22 in the first position, and at the same time drives the rotating bracket 313 to rotate along the first direction. When the motor 311 continues to rotate, it can drive the mounting bracket 10, the side sweeper 20, the lifting bracket 321 and the rotating bracket 313 to rotate synchronously together, so that the dirty substances on the ground or the table top can be cleaned; when the rotating shaft 3121 rotates along the second direction, the rotating bracket 313 is restricted by the rotating bracket 313 and descends relative to the mounting bracket 10 and presses down the main body 21 to switch the cleaning arm 22 to the second position, so as to avoid the cleaning arm 22 from being in contact with wet oil or water stains for a long time, and it can also avoid the side sweeper 20 from having too large a contact area with the carpet and the like, resulting in unsmooth movement, and it is convenient for the cleaning equipment to overcome obstacles.

[0054] Furthermore, the mounting hole 3131 in this embodiment is a non-circular hole, which may be an elliptical hole, a prismatic hole, etc. The second end of the lifting bracket 321 is adapted to the non-circular hole. Correspondingly, the second end of the lifting bracket 321 is elliptical or prismatic. Figures 6 to 8 3 shows the case where the second end of the lifting bracket 321 is arranged in a prismatic shape. With such an arrangement, when the motor 311 drives the rotating shaft 3121 to rotate along the second direction, the lifting bracket 321 can perform lifting motion under the restriction of the rotating bracket 313 to drive the cleaning arm 22 of the side sweeper 20 to switch from the first position to the second position. The lifting bracket 321 is provided with a connecting hole 3211, and the lifting bracket 321 is sleeved on the connecting column 103 through the connecting hole 3211, and a guide component is provided between the outer peripheral surface of the connecting column 103 and the inner wall surface of the connecting hole 3211. Through the function of the guide component, interference between the mounting bracket 10 and the lifting bracket 321 when rotating can be avoided.

[0055] Combination Figures 3 to 8As shown, the guide assembly in this embodiment includes a guide protrusion 1031 and an arc-shaped groove 3212, one of the arc-shaped groove 3212 and the guide protrusion 1031 is arranged on the outer peripheral surface of the connecting column 103, and the other is arranged on the inner wall surface of the connecting hole 3211, and the guide protrusion 1031 is inserted into the arc-shaped groove 3212 and can slide along the arc-shaped groove 3212. That is to say, when the arc-shaped groove 3212 is arranged on the inner wall surface of the connecting hole 3211, the guide protrusion 1031 is arranged on the outer peripheral surface of the connecting column 103; when the arc-shaped groove 3212 is arranged on the outer peripheral surface of the connecting column 103, the guide protrusion 1031 is arranged on the inner wall of the connecting hole 3211. The present application Figures 6 to 8 3 shows a situation where the arc-shaped groove 3212 is arranged on the inner wall surface of the connecting hole 3211 and the guide protrusion 1031 is arranged on the outer peripheral surface of the connecting column 103 .

[0056] During actual operation, when the motor 311 drives the rotating shaft 3121 to rotate in the first direction, the guide protrusion 1031 and the arc-shaped groove 3212 are relatively stationary, and the mounting bracket 10, the side sweeper 20, the lifting bracket 321, and the rotating bracket 313 rotate synchronously. At this time, the cleaning arm 22 of the side sweeper 20 is in the first position, which is convenient for cleaning dirty substances on the ground or the table top; when the motor 311 drives the rotating shaft 3121 to rotate in the second direction, since the one-way bearing 40 can only rotate in the first direction, correspondingly, the rotating bracket 313 remains stationary. At this time, since the mounting bracket 10 rotates along the second direction driven by the rotating shaft 3121, and a guide protrusion 1031 and an arc-shaped groove 3212 that are plugged into each other are provided between the lifting bracket 321 and the connecting column 103, the lifting bracket 321 can be lowered relative to the connecting column 103 under the joint action of the rotating bracket 313 and the guide assembly, and then a resisting force can be applied to the main body 21 installed inside the mounting cavity 101, and finally the cleaning arm 22 is driven to switch from the first position to the second position.

[0057] Optionally, the guide assembly in this embodiment includes multiple guide assemblies, and the multiple guide assemblies are arranged at intervals along the outer circumference of the connecting column 103. Exemplarily, the guide assemblies can be two, three or more than three. Figure 6 The case where there are two guide assemblies is shown in FIG. In this embodiment, by providing a plurality of guide assemblies, the stability of the lifting bracket 321 during the lifting process can be ensured, and the lifting bracket 321 can be prevented from being deflected.

[0058] During actual processing, the arc groove 3212 in this embodiment is bent and extended to a certain length along the height direction of the lifting bracket 321. When the lifting bracket 321 is lifted or lowered, the guide protrusion 1031 rotates with the connecting column 103 and slides along the arc groove 3212, thereby avoiding interference between the lifting bracket 321 and the guide protrusion 1031 when the lifting bracket 321 is lifted or lowered.

[0059] Exemplarily, the lifting bracket 321 in this embodiment is generally arranged in a ring shape, and the first end of the lifting bracket 321 is provided with an annular outer flange 3213, and the outer diameter of the annular outer flange 3213 is larger than the inner diameter of the avoidance hole 102. Such a configuration can prevent the first end of the lifting bracket 321 from falling off from the installation cavity 101, facilitate the limiting of the lifting bracket 321, and can improve the structural stability and reliability of the entire side-sweeping lifting device.

[0060] Furthermore, the mounting bracket 10 in the present embodiment includes a first shell 11 and a second shell 12. Among them, a connecting column 103 is provided on the first shell 11; the second shell 12 is buckled on the first shell 11 and is surrounded by the first shell 11 to form the aforementioned mounting cavity 101 and limiting hole 104, the cleaning arm 22 is passed through the limiting hole 104 and protrudes from the outer peripheral side of the mounting bracket 10, and the second shell 12 is provided with an avoidance hole 102, and the connecting column 103 is passed through the avoidance hole 102, and the structure is compact and stable. Exemplarily, the first shell 11 and the second shell 12 in the present embodiment can be connected by snap-fit ​​connection, or by screws, glue, welding or screws and other structural connections. As long as it is other deformation methods under the conception of the present application, they are all within the protection scope of the present application.

[0061] During assembly, the main body 21 is located in the installation cavity 101, and a positioning hole 211 is provided on the main body 21. The main body 21 is sleeved on the connecting column 103 through the positioning hole 211, and the structure is stable and reliable. The cleaning arm 22 passes through the outer peripheral side of the mounting bracket 10 from the limiting hole 104. When the lifting bracket 321 is raised or lowered, a force can be applied to the main body 21, thereby driving the cleaning arm 22 to deform at the limiting hole 104 to switch between the first position and the second position. The connecting column 103 passes through the second housing 12 from the avoidance hole 102, so as to be connected to the rotating shaft 3121.

[0062] Furthermore, a guide slope 1041 is provided on the side wall of the limiting hole 104 in this embodiment; a flexible connection portion 221 is provided at one end of the cleaning arm 22 close to the main body 21, and the cleaning arm 22 is connected to the main body 21 through the flexible connection portion 221; wherein the lifting bracket 321 applies an external force to the main body 21 to drive the flexible connection portion 221 to rise and fall along the guide slope 1041, and finally can drive the cleaning arm 22 to switch between the first position and the second position. Exemplarily, the flexible connection portion 221 in this embodiment can be a structure such as flexible silicone, flexible rubber, or a metal sheet with a certain degree of flexibility. When the lifting bracket 321 moves downward and applies downward pressure to the main body 21, the main body 21 can pull the flexible connection part 221 to deform along the guide inclined surface 1041, thereby driving the cleaning arm 22 to tilt toward the top of the mounting bracket 10 and be in the second position; conversely, when the lifting bracket 321 moves upward relative to the connecting column 103, the lifting bracket 321 cancels the downward pressure applied to the main body 21, and the cleaning arm 22 tilts toward the bottom of the mounting bracket 10 under the action of its own gravity and is in the first position, and the flexible connection part 221 is pulled up and reset, thereby driving the main body 21 to reset until the next time the lifting bracket 321 applies downward pressure to the main body 21. Of course, in other embodiments of the present application, elastic elements such as reset elasticity can also be set in the mounting cavity 101 to reset the main body 21, thereby switching the cleaning arm 22 from the second position to the first position. As long as it is other deformation methods under the conception of the present application, they are all within the protection scope of the present application.

[0063] For example, the cleaning arm 22 in this embodiment can be provided as one, or can be provided as two or more. Figure 6 The figure shows the situation when there are three cleaning arms 22, through the action of the three cleaning arms 22, it is convenient to quickly clean the dirty substances in the space. The end of the cleaning arm 22 close to the main body 21 can be provided with a rubber-encapsulated structure, and the end away from the main body 21 is provided with a plurality of bristles, which is convenient for effectively cleaning the ground or the table.

[0064] In order to facilitate assembly, the connection column 103 of this embodiment is provided with an insertion hole 1032, and a limiting step 1033 is provided on the inner wall surface of the insertion hole 1032, and a limiting spring piece 31211 is provided on the rotating shaft 3121. During installation, the end of the rotating shaft 3121 is inserted into the insertion hole 1032, and the limiting spring piece 31211 is locked on the limiting step 1033, so that the connection column 103 and the rotating shaft 3121 can be preliminarily positioned, and finally the connection column 103 and the rotating shaft 3121 can be fixedly connected together by using a locking screw or other structure, which is convenient to assemble and has a stable and reliable structure.

[0065] Of course, in other embodiments of the present application, the limiting spring piece 31211 may not be provided on the rotating shaft 3121, and correspondingly, the limiting step 1033 may not be provided in the plug-in hole 1032. The rotating shaft 3121 and the connecting column 103 are only locked by locking screws or the like. As long as other deformation methods are based on the conception of the present application, they are within the protection scope of the present application.

[0066] According to the above embodiments, it can be known that:

[0067] (1) When the side sweeper 20 of the present application rotates along the first direction, it can rub against the ground to clean up garbage and stains.

[0068] (2) When the side sweeper 20 of the present application rotates in a second direction opposite to the first direction, the rotating bracket 313 and the one-way bearing 40 rotate in the opposite direction and get stuck, and the lifting bracket 321 descends to squeeze the main body 21 of the side sweeper 20, and finally drives the cleaning arm 22 to achieve a retracting and lifting effect, avoiding dirt such as oil and water stains and avoiding multiple friction pollution.

[0069] (3) When the side sweeper 20 of the present application encounters a step carpet obstacle, the side sweeper 20 can be retracted and lifted to avoid it.

[0070] On the other hand, the present application also discloses a cleaning device, which may be, for example, a floor scrubber, a floor sweeper, or a cleaning base station having a floor scrubber or a floor sweeper, etc. Since the cleaning device includes the above-mentioned side-sweeping lifting device, the cleaning device includes all the technical effects of the above-mentioned side-sweeping lifting device. Since the technical effects of the side-sweeping lifting device have been described in detail above, they will not be repeated here.

[0071] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0072] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only to facilitate the distinction between corresponding components. If not otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0073] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
