[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0037] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a change in posture or a change in motion state, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0038] like Figure 1 , Figure 4 as well as Figure 5 As shown, the adjustment mechanism according to the embodiment of the present application is used for an intelligent cleaning device, and includes: a fixed bracket 10, a first bracket 20, a second bracket 30, an elastic component 40 and a driving component 50.

[0039] Specifically, the fixed bracket 10 is used to be installed on the chassis of the intelligent cleaning equipment; the first bracket 20 is movably arranged on the fixed bracket 10, and the first bracket 20 is used to install the cleaning component 2; the second bracket 30 is movably arranged below the first bracket 20; the two ends of the elastic component 40 are respectively connected to the first bracket 20 and the second bracket 30; the driving component 50 is transmission-connected to the second bracket 30 to drive the second bracket 30 to move.

[0040] In detail, the fixed bracket 10 is used to support the first bracket 20 and the second bracket 30, and the second bracket 30 is connected to the driving assembly 50 in a transmission connection. The first bracket 20 is arranged above the second bracket 30, and the two ends of the elastic assembly 40 are respectively connected to the first bracket 20 and the second bracket 30. The first bracket 20 relies on gravity to press on the elastic assembly 40, and indirectly relies on the second bracket 30 to support the first bracket 20. When the adjustment mechanism is applied to the intelligent cleaning device, when the second bracket 30 moves downward under the drive of the driving assembly 50, the first bracket 20 and the elastic assembly 40 move synchronously with the downward movement of the second bracket 30 until the cleaning assembly 2 contacts the ground. The first bracket 20 is subjected to the force and no longer moves. At this time, the second bracket 30 continues to move. The elastic assembly 40 releases pressure in this process, which can neutralize the dead weight of the cleaning assembly 2 until the second bracket 30 reaches the lowest point. The force of the elastic assembly 40 is completely released. At this time, the dead weight of the cleaning assembly 2 is also completely released, avoiding the rigid contact between the cleaning assembly 2 and the ground, thereby improving the overall service life of the adjustment mechanism.

[0041] In addition, when the intelligent cleaning device is cleaning the floor, if the cleaning component 2 moves to a floor with different uneven surfaces, the elastic component 40 enables the cleaning component 2 to adaptively shake up and down elastically, thereby reducing the wear of the cleaning component 2.

[0042] In this embodiment, the driving assembly 50 includes a fixed end and a driving end, the driving end is connected to the second bracket 30, and the fixed end is connected to the fixed bracket 10 or to the chassis of the intelligent cleaning device.

[0043] When cleaning is required, the second bracket 30 is lowered, and the first bracket 20 and the cleaning assembly 2 are lowered together with the second bracket 30 due to their own weight. When cleaning is not required, the second bracket 30 is raised, and the elastic component 40 is used to indirectly push the first bracket 20 and drive the cleaning assembly 2 to overcome its own weight and move away from the ground, so that the cleaning assembly 2 avoids contact with the ground, thereby extending the life of the cleaning assembly 2 and protecting the ground. In the process of descending and ascending, the elastic component 40 can play a buffering role for the cleaning assembly 2.

[0044] According to the adjustment mechanism of the embodiment of the present application, the elastic component 40 is used to realize that the gravity of the cleaning component 2 during the downward movement can be converted into a linear release, thereby avoiding the sudden force mutation when the second bracket 30 and the first bracket 20 are separated, and weakening the instantaneous sudden force exerted by the cleaning component 2 on the ground.

[0045] like Figure 1 and Figure 4As shown, according to the adjustment mechanism of the embodiment of the present application, a first limit member 11 is provided on the fixed bracket 10, and the second bracket 30 can move between a first position and a third position, the first position is higher than the third position, and there is a second position between the first position and the third position, and when the second bracket 30 moves to the second position, the first bracket 20 stops against the first limit member 11.

[0046] In detail, a first limit member 11 is provided on the fixed bracket 10, and the second bracket 30 can move between a first position and a third position, and the first position is higher than the third position, that is, the second bracket 30 can move to the first position at the highest, and the second bracket 30 can move to the third position at the lowest. When the second bracket 30 moves to the third position, the deadweight of the cleaning component 2 can be completely released. The first position and the third position are only used to limit the boundary position of the moving range of the second bracket 30, and are not limited to a specific position. When the second bracket 30 moves to the second position, the first bracket 20 stops against the first limit member 11. At this time, the first bracket 20 stops moving downward, and the second bracket 30 continues to move downward under the action of the driving assembly 50. The distance between the first bracket 20 and the second bracket 30 gradually increases, and the elastic assembly 40 begins to gradually release pressure. During this process, the elastic assembly 40 neutralizes the dead weight of the cleaning assembly 2. When the second bracket 30 continues to move downward to the third position, the pressure of the elastic assembly 40 is completely released. At this time, the dead weight of the cleaning assembly 2 is also completely released, thereby achieving that the gravity of the cleaning assembly 2 during the downward movement can be converted into a linear release, avoiding the sudden change in force when the second bracket 30 and the first bracket 20 are separated, and weakening the instantaneous sudden force exerted on the ground by the cleaning assembly 2.

[0047] In a specific embodiment, the elastic component 40 includes a spring 41, and the number of the spring 41 is one or more. When the number of the spring 41 is multiple, the multiple springs 41 are distributed in sequence along the length direction of the first bracket 20, so that the first bracket 20 can be evenly buffered in the length direction, thereby improving the stability of the cleaning component 2 during the rising and falling process.

[0048] like Figure 1 , Figure 3 as well as Figure 4 As shown, in some embodiments, a first guide member 12 is disposed on the fixed bracket 10, and a second guide member 21 is disposed on the first bracket 20, and the first guide member 12 and the second guide member 21 cooperate with each other.

[0049] In detail, a first guide member 12 is provided on the fixed bracket 10, and a second guide member 21 is provided on the first bracket 20. During the upward and downward movement of the first bracket 20, the cooperation of the first guide member 12 and the second guide member 21 can enable the first bracket 20 to move along a predetermined trajectory, thereby avoiding deviation or jamming of the first bracket 20 and improving the reliability of the movement process of the first bracket 20.

[0050] like Figure 1 , Figure 3 as well as Figure 4 As shown, in some embodiments, the first guide member 12 is configured as a guide column 121, the second guide member 21 is configured as a sleeve 211, and a second limit member is provided on the guide column 121. When the second bracket 30 moves to the second position, the sleeve 211 abuts against the second limit member.

[0051] In detail, the first guide member 12 is configured as a guide column 121, and the second guide member 21 is configured as a sleeve 211. A second limit member is provided on the guide column 121. When the second bracket 30 moves to the second position, the sleeve 211 abuts against the second limit member. That is to say, when the second bracket 30 moves to the second position, the first limit member 11 abuts against the first bracket 20, and the sleeve 211 abuts against the second limit member, and the sleeve 211 is connected to the first bracket 20, so that the cleaning component 2 can be supported by the first limit member 11 and the second limit member. Since the first limit member 11 and the second limit member are in different positions, the cleaning component 2 can be better balanced and more stable when moving on the ground, especially when cleaning on an uneven ground, it can ensure that the cleaning component 2 can reduce jitter during the adaptive self-adjustment process.

[0052] In a specific embodiment, one of the first guide member 12 and the second guide member 21 is configured as a slide rail, and the other one is configured as a slider.

[0053] like Figure 1 and Figure 2 As shown, in some embodiments, the driving assembly 50 includes a power unit 51 and a transmission group 52, the transmission group 52 includes a screw rod 521 and a sliding nut 522 sleeved on the screw rod 521, the power unit 51 is transmission-connected to the screw rod 521, and the sliding nut 522 is connected to the second bracket 30.

[0054] Specifically, the transmission group 52 includes a screw rod 521 and a sliding nut 522 sleeved on the screw rod 521. The screw rod 521 is threadedly connected to the sliding nut 522. By changing the rotation direction of the screw rod 521, the sliding nut 522 can be driven to move upward or downward. During the movement, the sliding nut 522 drives the second bracket 30 to move synchronously.

[0055] It is understandable that the transmission power of the screw 521 is small and the speed is slow, which can buffer and disperse sudden impact loads. Due to the different road conditions and the unevenness of the ground, this advantage is particularly prominent for intelligent cleaning equipment, which can ensure that the intelligent cleaning equipment can respond to ground changes in a timely manner and improve the service life of the overall structure. At the same time, since the lifting range of the cleaning component 2 is not large during the descent of the cleaning component 2, it is necessary to more accurately control the movement of the screw 521, and the combination of the screw 521 and the sliding nut 522 has this advantage, with high transmission accuracy and strong controllability.

[0056] The power unit 51 is an electric motor, so that one electric motor can drive the two screw rods 521 to rotate, thereby reducing the number of parts of the adjustment mechanism and making the overall structure more compact.

[0057] like Figure 1-Figure 4 As shown, in some embodiments, the transmission group 52 also includes a first transmission gear 523, a second transmission gear 524 and a transmission rod 525. The second transmission gear 524 is arranged on the transmission rod 525, the first transmission gear 523 is meshed with the second transmission gear 524, and the first transmission gear 523 is also connected to the power unit 51 for transmission. First bevel gears 526 are provided at both ends of the transmission rod 525, and a second bevel gear 527 is provided on the screw rod 521, and the first bevel gear 526 and the second bevel gear 527 are meshed.

[0058] In detail, in order to make the cleaning component 2 more stable during the lifting process, two screw rods 521 are provided, and the two screw rods 521 are respectively located at the two ends of the transmission rod 525, and the power unit 51, the first transmission gear 523 and the second transmission gear 524 are sequentially transmitted, that is, the power unit 51 drives the first transmission gear 523 to rotate, the first transmission gear 523 rotates to drive the second transmission gear 524 to rotate, and the second transmission gear 524 rotates to drive the transmission rod 525 to rotate synchronously (there is no relative rotation between the second transmission gear 524 and the transmission rod 525), and the transmission rod 525 rotates to drive the first bevel gear 526 to rotate (there is no relative rotation between the transmission rod 525 and the first bevel gear 526), ​​the first bevel gear 526 rotates to drive the second bevel gear 527 to rotate, and the second bevel gear 527 rotates to drive the screw rod 521 to rotate, and the screw rod 521 rotates to drive the sliding nut 522 to move up and down. It can be understood that by changing the rotation direction of the power unit 51, that is, the output shaft of the motor, the sliding nut 522 can be moved up or down.

[0059] Among them, the transmission direction of the power unit 51 can be changed through the transmission rod 525, and most of the structures of the transmission group 52 (transmission rod 525, first transmission gear 523, second transmission gear 524) are horizontally arranged above the first bracket 20, which can reasonably set the internal structure position, improve space utilization, and thus reduce the overall space occupancy.

[0060] like Figure 3 As shown, in a specific embodiment, a bearing 53 is sleeved on the transmission shaft, and the bearing 53 is fixedly supported on the fixing bracket 10, so that the transmission shaft can be supported by the fixing bracket 10, thereby improving the assembly stability of the transmission shaft.

[0061] Furthermore, there are two bearings 53 , which are symmetrically arranged on both sides of the second transmission gear 524 and between the two first bevel gears 526 . Such reasonable arrangement of the force points can make the transmission shaft more stable during transmission.

[0062] like Figure 1 and Figure 5 As shown, in some embodiments, the first bracket 20 includes a main body 201 and a clamping portion 202 disposed on the main body 201, the main body 201 is connected to the cleaning component 2, the clamping portion 202 is used to stop with the first limiting member 11, the power portion 51 and the transmission rod 525 are both disposed above the clamping portion 202, and the position of the first limiting member 11 is higher than the main body 201.

[0063] In detail, the first bracket 20 includes a main body 201 and a clamping portion 202 disposed on the main body 201, the main body 201 is connected to the cleaning assembly 2, the clamping portion 202 is used to stop with the first limiter 11, the power unit 51 and the transmission rod 525 are both disposed above the clamping portion 202, and the internal structure position can be reasonably arranged to improve the space utilization rate, thereby reducing the overall space occupancy. The position of the first limiter 11 is higher than the main body 201, and the clamping portion 202 extends toward the side away from the second bracket 30, so that it can stop with the first limiter 11. In this way, in terms of spatial layout, the clamping portion 202 and the first limiter 11 can be arranged in the same space as the power unit 51 in the height direction, further reasonably arranging the spatial structure, improving the space utilization rate, thereby reducing the overall space occupancy.

[0064] In a specific embodiment, one end of the clamping portion 202 extends from the main body 201 to the other end to form a bent structure. In this way, a part of the structure is used to change the height of the clamping portion 202, and another part of the structure is used to stop with the first limit member 11, thereby simplifying the overall structural setting. The clamping portion 202 and the main body 201 are integrally formed and can be stamped from sheet metal, thereby improving the overall structural strength and reducing the difficulty of processing.

[0065] like Figure 1 , Figure 4 as well as Figure 5 As shown, according to the adjustment mechanism of the embodiment of the present application, a limiting column is provided on the second bracket 30, and the elastic component 40 includes a spring 41, which is sleeved on the limiting column, and the end of the limiting column away from the second bracket 30 is spaced from the first bracket 20.

[0066] In detail, a limiting column is provided on the second bracket 30, and the elastic component 40 includes a spring 41, which is sleeved on the limiting column, so that the spring 41 can be guided by the limiting column to prevent the spring 41 from getting stuck during the extension or compression process. The end of the limiting column away from the second bracket 30 is spaced from the first bracket 20, which can prevent the first bracket 20 and the second bracket 30 from being blocked by the limiting column when they are relatively close.

[0067] like Figure 2 and Figure 3 As shown, according to the adjustment mechanism of the embodiment of the present application, it also includes a tension spring 60, a first connecting part 22 is provided on the first bracket 20, and a second connecting part 31 is provided on the second bracket 30, and two ends of the tension spring 60 are respectively connected to the first connecting part 22 and the second connecting part 31.

[0068] In detail, a first connecting portion 22 is provided on the first bracket 20, and a second connecting portion 31 is provided on the second bracket 30. The first connecting portion 22 extends from a plane where the upper end of the main body portion 201 is located, and the second connecting portion 31 is located at the lower end of the first connecting portion 22 and opposite to the first connecting portion 22. In this way, the first connecting portion 22 and the second connecting portion 31 are connected by a tension spring 60. When the first bracket 20 and the second bracket 30 move relative to each other, the tension spring 60 is used to ensure that the elastic component 40 will not disengage during the process of releasing pressure, and can still be reset during the next compression process, thereby ensuring that the first bracket 20 and the second bracket 30 can move according to a predetermined trajectory.

[0069] It is understandable that due to the presence of the tension spring 60, when cleaning on different road surfaces, the positions of the first bracket 20 and the second bracket 30 relative to the fixed bracket 10 may change, but the maximum distance between the first bracket 20 and the second bracket 30 may remain constant, because the first bracket 20 and the second bracket 30 need to overcome the tension of the tension spring 60 to move away from each other. In this way, the intelligent cleaning device can be adaptively adjusted when operating on road surfaces under different working conditions.

[0070] In a specific embodiment, there are two tension springs 60, two first connecting parts 22 are provided on the first bracket 20, and two second connecting parts 31 are provided on the second bracket 30. The tension spring 60, the first connecting part 22 and the second connecting part 31 are all located between the two screw rods 521. In this way, the lateral width of the adjustment mechanism can be reduced.

[0071] In the height direction, the first connection part 22, the tension spring 60 and the second connection part 31 are all lower than the first limit member 11 and are arranged below the transmission rod 525, thereby improving the overall structural utilization and reducing the overall volume.

[0072] The intelligent cleaning device according to the embodiment of the present application includes the above-mentioned adjustment mechanism.

[0073] According to the intelligent cleaning device of the embodiment of the present application, the adjustment mechanism uses the elastic component 40 to realize that the gravity of the cleaning component 2 during the downward movement can be converted into a linear release, thereby avoiding the sudden change of force when the second bracket 30 and the first bracket 20 are separated, and weakening the instantaneous sudden force exerted by the cleaning component 2 on the ground, thereby improving the overall service life of the intelligent cleaning device.
