Description

Technical Field

[0002] With the iterative update and development of technology, self-cleaning equipment has entered into the life of ordinary families and has gradually become popular.

[0003] Among the current self-cleaning equipment, some self-cleaning equipment uses crawler-type cleaning parts, namely crawler mops, which are installed on the self-cleaning equipment through brackets. The existing brackets are usually a main and auxiliary dual-axis structure, with the main axis fixed and the auxiliary axis being able to move laterally relative to the main axis, thereby achieving the tensioning and loosening of the crawler mop, and thus disassembling and assembling the crawler mop. Since the auxiliary axis is a movable structure, the existence of a movable gap will cause the auxiliary axis to vibrate when mopping the floor, causing the contact state between the crawler mop and the ground to change continuously, affecting the cleaning effect.

[0049] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0050] See also Figures 1 to 4 As shown, an embodiment of the first aspect of the present application provides a track mechanism, including: a track bracket 1; a transmission assembly 2, the transmission assembly 2 is rotatably connected to the track bracket 1; a tensioning assembly 3, the tensioning assembly 3 is movably connected to the track bracket 1 and is parallel to the transmission assembly 2; a cleaning track 4, the cleaning track 4 is annular in structure, and the cleaning track 4 is detachably mounted on the transmission assembly 2 and the tensioning assembly 3; wherein the tensioning assembly 3 is suitable for switching between a first operating position and a second operating position and being fixed in the first operating position, when the tensioning assembly 3 is in the first operating position, the cleaning track 4 is in an assembled state, and when the tensioning assembly 3 is in the second operating position, the cleaning track 4 is in a disassembled state.

[0051] By providing the tensioning assembly 3, it is convenient to detach the cleaning track 4 separately for deep cleaning, thereby improving the subsequent cleaning effect and the user experience. When the cleaning track 4 reaches the end of its service life, only the cleaning track 4 needs to be replaced without replacing the entire track mechanism, thereby effectively reducing the cost of use. In addition, since the position of the transmission assembly 2 relative to the track bracket 1 is fixed, the tensioning state of the cleaning track 4 is changed by switching the tensioning assembly 3 between the first operating position and the second operating position, thereby avoiding changes in the contact state between the cleaning track 4 and the surface to be cleaned, ensuring that the cleaning track 4 can fully contact the surface to be cleaned, thereby reducing vibration and maintaining a stable cleaning effect.

[0052] The crawler mechanism includes a crawler support 1, a transmission assembly 2, a tensioning assembly 3 and a cleaning crawler 4. The crawler support 1 is used to carry the transmission assembly 2 and the tensioning assembly 3, and the cleaning crawler 4 is sleeved on the transmission assembly 2 and the tensioning assembly 3.

[0053] Specifically, the crawler support 1 has a mounting side, and the cleaning crawler 4 can be detachably wound on the transmission assembly 2 and the tensioning assembly 3 from the mounting side of the crawler support 1. The mounting side of the crawler support 1 is provided with a support end cover 11, which is used to limit the transmission assembly 2 and the tensioning assembly 3 in the length direction of the crawler support 1, thereby preventing the cleaning crawler 4 from deviating and ensuring the reliability of the rotation of the crawler mechanism.

[0054] The transmission assembly 2 is rotatably arranged on the track bracket 1, and the cleaning track 4 is connected to the transmission assembly 2. The rotation of the transmission assembly 2 can drive the cleaning track 4 to rotate. The outer surface of the cleaning track 4 is a cleaning working surface to clean the dirt on the surface to be cleaned. The surface to be cleaned can be a carpet or the ground.

[0055] The tensioning assembly 3 is movably arranged on the track support 1 , so that the tensioning assembly 3 can be switched between a first operating position and a second operating position, thereby changing the tensioning state of the cleaning track 4 .

[0056] Specifically, the tensioning assembly 3 is parallel to the transmission assembly 2. When the tensioning assembly 3 is switched to the first operating position and fixed, the cleaning track 4 is connected to the transmission assembly 2 and the tensioning assembly 3 respectively, and the cleaning track 4 is in a tensioned state; when the tensioning assembly 3 is switched to the second operating position, the tensioning assembly 3 is separated from the cleaning track 4, and the cleaning track 4 is in a loose state. It can be understood that when the tensioning assembly 3 is in the first operating position, the distance between the tensioning assembly 3 and the track bracket 1 is greater than the distance between the tensioning assembly 3 and the track bracket 1 when the tensioning assembly 3 is in the second operating position.

[0057] In the present application, when the cleaning belt 4 needs to be installed, the cleaning belt 4 can be firstly sleeved on the transmission assembly 2 and the tensioning assembly 3 from the installation side, and then the tensioning assembly 3 can be controlled to switch from the second operating position to the first operating position and fixed; when the cleaning belt 4 needs to be detached, the tensioning assembly 3 can be firstly controlled to switch from the first operating position to the second operating position, and then the cleaning belt 4 can be taken out from the installation side.

[0058] In some possible implementations provided in this application, see Figure 2 As shown, the transmission assembly 2 includes: an active roller 21, which is used for transmission connection with the driving structure; at least one driven roller 22, at least one driven roller 22 is parallel to the active roller 21, and the active roller 21 is suitable for driving at least one driven roller 22 and the cleaning track 4 to rotate synchronously.

[0059] The transmission assembly 2 includes at least two roller bodies arranged in parallel, the roller body has a first end and a second end arranged opposite to each other, the first end is located at the installation side of the track bracket 1, and the first end is rotatably connected to the bracket end cover 11, and the cleaning track 4 can be sleeved on the roller body from the first end along the axial direction of the roller body. A mutual transmission structure is formed between the cleaning track 4 and the roller body to drive the cleaning track 4 to rotate synchronously when the roller body rotates.

[0060] Specifically, at least two roller bodies include an active roller 21, and the active roller 21 is used for transmission connection with the driving structure of the floor brush. The driving structure is arranged on the same side of the bracket end cover 11 as the active roller 21 or on the side away from the active roller 21. As long as the active roller 21 can be driven to rotate, the specific connection method belongs to the well-known technology in the field and is not repeated here; the driving structure can be a motor, and the driving end of the driving structure is connected to the active roller 21 for driving the active roller 21 to rotate. The driving end of the driving structure can be understood as the motor shaft of the motor.

[0061] Among them, at least two roller bodies also include at least one driven roller 22, at least one driven roller 22 is parallel to the active roller 21, and the position of at least one driven roller 22 contacting the cleaning belt 4 on the side close to the surface to be cleaned and the position of the active roller 21 contacting the cleaning belt 4 on the side close to the surface to be cleaned are located in the same plane, so that the cleaning belt 4 is in full contact with the surface to be cleaned, thereby improving the cleaning effect.

[0062] Among them, both the active roller 21 and the driven roller 22 can support the cleaning track 4, and the number of the driven rollers 22 can be selected according to the contact area between the cleaning track 4 and the surface to be cleaned, and this application does not make further restrictions. It can be understood that the more the number of driven rollers 22 is set, the more positions the cleaning track 4 is supported, and the better the contact effect between the cleaning track 4 and the surface to be cleaned.

[0063] Specifically, in the embodiment of the present application, only one driven roller 22 is provided, and the driven roller 22 and the active roller 21 are respectively provided on both sides of the crawler support 1 .

[0064] The diameter of the driven roller 22 is smaller than that of the active roller 21 , which provides installation space for the tensioning assembly 3 . The tensioning assembly 3 is arranged on the side of the driven roller 22 away from the surface to be cleaned.

[0065] In some possible implementations provided in this application, see Figure 2 As shown, the tensioning assembly 3 includes: a tensioning bracket 31 slidably connected to the track bracket 1 ; and at least one tensioning roller 32 rotatably connected to the tensioning bracket 31 .

[0066] The tensioning assembly 3 includes a tensioning bracket 31 and a tensioning roller 32. The tensioning bracket 31 is roughly U-shaped and is used to carry the tensioning roller 32. The tensioning roller 32 is located on the side of the tensioning bracket 31 away from the active roller 21. The tensioning roller 32 is rotatably arranged on the tensioning bracket 31. A mutual transmission structure is formed between the tensioning roller 32 and the cleaning track 4. When the driving structure drives the active roller 21 to rotate, the active roller 21 can drive the driven roller 22, the tensioning roller 32 and the cleaning track 4 to rotate synchronously.

[0067] The tensioning roller 32 is used to support the cleaning track 4, and at least one tensioning roller 32 is provided. It can be understood that the more the number of tensioning rollers 32 is provided, the more positions the cleaning track 4 is supported, and the better the tensioning effect of the cleaning track 4. In the embodiment of the present application, one tensioning roller 32 is provided.

[0068] Specifically, the tensioning bracket 31 is slidably connected to the track bracket 1, and the tensioning bracket 31 is suitable for driving the tensioning roller 32 to move between the first operating position and the second operating position. In the embodiment of the present application, the diameter of the tensioning roller 32 is the same as the diameter of the driven roller 22. When the tensioning bracket 31 drives the tensioning roller 32 to move to the first operating position, the tensioning roller 32 is arranged opposite to the driven roller 22 in a direction perpendicular to the surface to be cleaned. At this time, the axis of the active roller 21, the axis of the driven roller 22 and the axis of the tensioning roller 32 are distributed in an isosceles triangle, and the axis of the active roller 21 coincides with the vertex of the isosceles triangle. The cleaning track 4 is in a tensioned state and is connected to the active roller 21, the driven roller 22 and the tensioning roller 32 respectively.

[0069] In the above embodiment, the crawler support 1 is provided with a first sliding portion 12 , and the tensioning support 31 is provided with a second sliding portion 311 that cooperates with the first sliding portion 12 to form a sliding connection.

[0070] The first sliding portion 12 and the second sliding portion 311 are provided to guide the movement of the tensioning bracket 31 on the crawler bracket 1, thereby ensuring that the tensioning roller 32 can stably switch between the first operating position and the second operating position.

[0071] Among them, the first sliding part 12 is arranged on the track bracket 1, and the second sliding part 311 is arranged on the tensioning bracket 31. The first sliding part 12 is slidably connected with the second sliding part 311 so that the tensioning bracket 31 can move on the track bracket 1, that is, the position of the tensioning roller 32 relative to the track bracket 1 can be changed, and the tensioning roller 32 can be switched between the first operating position and the second operating position.

[0072] Specifically, the moving direction of the tension bracket 31 is the length direction of the first sliding part 12 .

[0073] In specific applications, see Figure 2 and Figure 3As shown, the first sliding portion 12 is a slide groove, the second sliding portion 311 is a slider, the slide groove extends along the tensioning assembly 3 toward the transmission assembly 2, and the slider is slidably disposed in the slide groove.

[0074] The slide groove may be a through hole, and the slider may be a protrusion.

[0075] There are two slide grooves and two sliders, the two slide grooves are respectively opened on the end covers of the crawler bracket 1 on both sides, the two sliders are respectively arranged at the two ends of the tensioning bracket 31, and the two sliders are slidably arranged in the two slide grooves in a one-to-one correspondence.

[0076] In one embodiment, the chute extends in the direction from the tension roller 32 to the active roller 21, that is, extends in the transverse direction; in another embodiment, the chute extends in the direction from the tension roller 32 to the driven roller 22, that is, extends in the longitudinal direction. In the embodiment of the present application, the chute extends in the direction from the tension roller 32 to the active roller 21.

[0077] Specifically, when the tensioning assembly 3 switches from the first operating position to the second operating position, the tensioning bracket 31 moves along the radial direction of the tensioning roller 32 toward the track bracket 1 , and vice versa, the tensioning bracket 31 moves along the radial direction of the tensioning roller 32 away from the track bracket 1 .

[0078] In addition, the first sliding portion 12 and the second sliding portion 311 may also be arranged in the following manner:

[0079] The first sliding part 12 is a slideway, and the second sliding part 311 is a slide rail. The slideway extends along the axial direction of the transmission assembly 2, and the slide rail is slidably disposed in the slideway.

[0080] The slideway may be a continuous groove, and the slide rail may be a continuous protrusion.

[0081] The slideway is arranged on the side of the crawler support 1 away from the active roller 21 , and the slide rail is arranged on the side of the tensioning support 31 close to the active roller 21 .

[0082] It can be understood that, since the slideway extends along the axial direction of the active roller 21 , the tensioning assembly 3 can be taken out separately when the cleaning track 4 is detached.

[0083] Furthermore, the tensioning assembly 3 may also be arranged in the following manner:

[0084] The tensioning assembly 3 includes: a tensioning bracket 31 , which is rotatably connected to the track bracket 1 through a swing arm; and at least one tensioning roller 32 , which is rotatably connected to the tensioning bracket 31 .

[0085] By providing a swing arm, the tensioning roller 32 can rotate in space relative to the track support 1, thereby achieving the purpose of changing the tensioning state of the cleaning track 4.

[0086] The swing arm is rotatably arranged on the crawler support 1 and is connected to the tensioning support 31 .

[0087] Specifically, the first end of the swing arm is connected to the tensioning bracket 31, and the second end is hinged to the track bracket 1. The swing arm can rotate with the hinge point between the second end and the track bracket 1 as the rotation center, thereby driving the tensioning bracket 31 connected to the first end to rotate, and driving the tensioning roller 32 to switch between the first operating position and the second operating position through the tensioning bracket 31, thereby achieving the purpose of changing the tensioning state of the cleaning track 4.

[0088] The second end of the swing arm is provided with a rotating shaft, which passes through the end cover of the track bracket 1 along the length direction of the track bracket 1 and is exposed outside the track bracket 1 and connected to the knob. The rotating knob can drive the swing arm to rotate through the rotating shaft, thereby driving the tensioning assembly 3 to switch between the first operating position and the second operating position. When the cleaning track 4 needs to be installed, the cleaning track 4 can be first sleeved on the transmission assembly 2 and the tensioning assembly 3 from the installation side, and then the knob is turned to control the tensioning assembly 3 to rotate from the second operating position to the first operating position and fixed; when the cleaning track 4 needs to be detached, the knob can be first turned to control the tensioning assembly 3 to rotate from the first operating position to the second operating position, and then the cleaning track 4 can be taken out from the installation side.

[0089] Two swing arms may be provided, and the two swing arms are relatively arranged on both sides of the tensioning assembly 3 along the length direction of the tensioning assembly 3 .

[0090] Alternatively, the tensioning assembly 3 may also be arranged as follows:

[0091] The tensioning assembly 3 includes: a tensioning bracket 31 , which is connected to the track bracket 1 through a folding portion; and at least one tensioning roller 32 , which is rotatably connected to the tensioning bracket 31 .

[0092] By providing the folding portion, the tensioning assembly 3 can be driven to move relative to the track bracket 1 and can be switched between the first operating position and the second operating position, thereby achieving the purpose of changing the tensioning state of the cleaning track 4.

[0093] Among them, the folding part can be a scissor arm or a telescopic rod, etc., and this application does not make further limitations. In the embodiment of this application, the folding part is a scissor arm.

[0094] Specifically, the scissor arm is arranged between the track support 1 and the tensioning support 31, the first end of the scissor arm is hinged to the tensioning support 31, and the second end is hinged to the track support 1. When the cleaning track 4 needs to be installed, the cleaning track 4 can be firstly sleeved on the transmission assembly 2 and the tensioning assembly 3 from the installation side, and then the blades of the scissor arm are controlled to move toward each other to drive the tensioning assembly 3 to move from the second operating position to the first operating position and fix it; when the cleaning track 4 needs to be detached, the blades of the scissor arm can be controlled to move away from each other to drive the tensioning assembly 3 to rotate from the first operating position to the second operating position, and then the cleaning track 4 can be taken out from the installation side.

[0095] It can be understood that when the blades of the scissor arms move toward each other, the blade opening of the scissor arms decreases, which can lift the tensioning bracket 31 and move it away from the track bracket 1 to the first operating position; when the blades of the scissor arms move away from each other, the blade opening of the scissor arms increases, which can drop the tensioning bracket 31 and move it close to the track bracket 1 to the second operating position.

[0096] In some possible implementations provided in this application, see Figure 3 and Figure 4 As shown, a first locking portion 312 is provided on the tensioning bracket 31, and a second locking portion 13 is provided on the track bracket 1; when the cleaning track 4 is in an assembled state, the first locking portion 312 cooperates with the second locking portion 13 to limit the distance between the tensioning bracket 31 and the track bracket 1.

[0097] By providing the first locking portion 312 and the second locking portion 13, the tensioning assembly 3 can be fixed in the first operating position, thereby improving the tensioning effect of the cleaning track 4, so that the cleaning track 4 can fully contact the surface to be cleaned and maintain a stable cleaning effect.

[0098] The first locking portion 312 is disposed on the tensioning bracket 31 , and the second locking portion 13 is disposed on the track bracket 1 .

[0099] Among them, one of the first locking portion 312 and the second locking portion 13 can be a locking hole, and the other can be a buckle. The locking hole and the buckle are interference fit in the direction perpendicular to the axial direction of the tensioning roller 32, which can prevent the tensioning assembly 3 from vibrating when subjected to external force, thereby improving the tensioning effect of the cleaning track 4.

[0100] When the tensioning assembly 3 moves to the first operating position, the buckle is embedded in the lock hole.

[0101] Specifically, when the cleaning belt 4 needs to be installed, the cleaning belt 4 can be first mounted on the transmission assembly 2 and the tensioning assembly 3 from the installation side, and then the tensioning assembly 3 is controlled to move from the second operating position to the first operating position. Finally, when the tensioning assembly 3 moves to the first operating position, the tensioning assembly 3 is fixed in the first operating position through the cooperation of the first locking portion 312 and the second locking portion 13.

[0102] In specific applications, see Figure 3 and Figure 4 As shown, the first locking portion 312 is a handle, and the second locking portion 13 is a limiting groove. The handle is rotatably connected to the tensioning bracket 31, and the end of the handle away from the tensioning bracket 31 has a limiting block. When the tensioning assembly 3 is switched to the first operating position, the limiting block can be embedded in the limiting groove.

[0103] In the embodiment of the present application, the first locking portion 312 is a handle, and the end of the handle away from the tensioning bracket 31 has a limit block, and the limit block is a buckle.

[0104] The second locking portion 13 is a limiting groove, which is a locking hole. It can be understood that the limiting groove and the sliding groove can be the same groove.

[0105] The handle is arranged at the end of the tensioning bracket 31 , and the limiting groove is opened on the end cover of the crawler bracket 1 .

[0106] Specifically, the handle is rotatably connected to the tensioning bracket 31, and rotating the handle can switch the working state of the handle. The working state of the handle includes a first state and a second state. When the handle is in the first state, the handle is parallel to the end cover of the track bracket 1, and the limit block at the end of the handle can be embedded in the limit groove.
