Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning mechanism and a cleaning equipment. Background Art

[0002] Cleaning equipment such as smart sweepers face many challenges in daily use, among which obstacles when crossing thresholds or passing through carpets are particularly prominent. When encountering such situations, the machine often stops running due to the inability to pass smoothly, seriously affecting its cleaning efficiency and degree of automation.

[0003] Traditional sweepers use a method of adding a set of drivers to lift the cleaning components. Although this method can solve the problem of passing over thresholds and carpets to a certain extent, research has found that it also brings some new problems:

[0004] Considering the structural space, the additional drive needs to occupy a considerable part of the internal space, which is undoubtedly a double whammy for the already compact layout of the sweeper. The limited space is further compressed, which not only makes the installation and layout of other components more difficult, but also may affect the heat dissipation performance of the whole machine.

[0005] From the perspective of power consumption, the additional drive will inevitably consume more power. In the mode where the smart sweeper relies on battery power to achieve autonomous mobile cleaning, the increase in power consumption means a decrease in battery life, which in turn poses a potential threat to the stability and service life of the machine.

[0006] From a cost perspective, an extra set of drivers means more parts procurement, production and processing, and assembly and debugging costs. These extra costs will eventually be passed on to product prices, weakening the competitiveness of the sweeper in the market. Summary of the invention

[0061] The technical solutions of the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments in the embodiments of the present application are within the scope of protection of the embodiments of the present application.

[0062] In the description of the embodiments of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0063] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a replaceable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0064] The embodiment of the present application discloses a cleaning mechanism.

[0065] See also Figures 1 to 3 , an embodiment of a cleaning mechanism provided in the embodiments of the present application includes:

[0066] The mechanism body 1, the driving component 2, the self-locking component 4 and the traction component 3.

[0067] As for the mechanism body 1, it has the same composition as a conventional gear box structure, including a box shell 11 and a box cover 12. The box cover 12 is detachably mounted on the opening surface of the box shell 11 to form an installation cavity between the box shell 11 and the box cover 12.

[0068] The driving component 2 is installed on the mechanism body 1 and connected to the cleaning member of the cleaning component 6. The cleaning component 6 is a cleaning component arranged in the middle of the bottom surface of the cleaning device, specifically including a fixed seat 61 and a cleaning member (not shown in the figure) rotatably arranged in the fixed seat 61 (wherein the cleaning member can be, for example, a roller brush), and there is no specific limitation.

[0069] The traction component 3 connects the mechanism body 1 and the base 7. The base 7 is the bottom bearing structure of the cleaning equipment. The mechanism body 1 is connected to the fixed seat 61 of the cleaning component 6, and the fixed seat 61 of the cleaning component 6 is rotatably installed on the base 7 through its own rotating arm 611. The details are not repeated here.

[0070] The driving shaft 20 of the driving component 2 can rotate around a first direction and a second direction opposite to the first direction. It can be understood that the driving shaft 20 can realize forward and reverse rotation, wherein the rotation in the first direction can refer to forward rotation or reverse rotation. The specific design can be changed according to actual needs without limitation.

[0071] When the driving shaft 20 of the driving assembly 2 rotates in the first direction, the cleaning member can be driven to rotate; and when the driving shaft 20 of the driving assembly 2 rotates in the second direction, the traction assembly 3 can be driven to move to drive the mechanism body 1 to lift relative to the base 7; taking the rotation in the first direction as the forward rotation as an example, it can be understood that when the first direction is rotated forward, the cleaning member of the cleaning assembly 6 is normally driven to rotate, but the traction assembly 3 will not be driven to drive the mechanism body 1 to lift relative to the base 7. When the reverse rotation is performed, the traction assembly 3 can be driven to move to drive the mechanism body 1 to lift relative to the base 7. Since the mechanism body 1 is connected to the fixed seat 61 of the cleaning assembly 6, the fixed seat 61 and the cleaning assembly 6 are synchronously driven to lift relative to the base 7, realizing one-to-two control.

[0072] The self-locking component 4 is installed on the main body 1 of the mechanism, and can be locked and connected with the traction component 3 to lock the traction component 3 when the cleaning component 6 is lifted to a preset height; it can be understood that when the fixing seat 61 of the cleaning component 6 is lifted into place, the self-locking component 4 utilizes its own self-locking function to lock and connect with the traction component 3 to achieve locking of the traction component 3, thereby achieving self-locking of the traction component 3 and ensuring that the cleaning component 6 is in a stable and reliable lifting height position.

[0073] The cleaning mechanism designed in this application has the following beneficial effects:

[0074] 1. A set of driving components 2 realizes the cleaning and lifting functions of the cleaning component 6. Compared with the traditional design of adding an additional set of drivers, it saves structural space, reduces power consumption and saves production costs, greatly improves the competitiveness of cleaning products, and provides users with a better use experience.

[0075] 2. The self-locking component 4 is used to realize the functions of automatic locking and automatic unlocking in place, which ensures the stability of the mechanism and makes it more reliable to use.

[0076] The automatic locking function prevents the cleaning component 6 from being displaced or accidentally dropped due to external vibrations, collisions or other interference factors. During the cleaning process, even if bumps occur when crossing obstacles such as thresholds and carpets, the cleaning component 6 can always remain in the set lifting position to ensure the stable progress of the cleaning work. This not only improves the cleaning quality, but also reduces the risk of damage to the ground or itself caused by abnormal movement of the cleaning component 6, and extends the service life of the cleaning product. This function of automatic locking and unlocking in place makes the mechanical operation of the entire cleaning product more intelligent and automated. Users do not need to worry about poor cleaning results or equipment damage due to improper manual operation, and it also reduces the frequency and cost of equipment maintenance. For large-scale cleaning products, this stable and reliable mechanism design can improve the product yield, reduce after-sales maintenance costs, and further enhance the product's market competitiveness and user satisfaction.

[0077] Moreover, the unlocking component 5 is also driven by the driving component 2, and there is no need to increase the unlocking driving source, and the overall structure is more compact.

[0078] The above is the first embodiment of the cleaning mechanism provided in the embodiment of the present application. The following is the second embodiment of the cleaning mechanism provided in the embodiment of the present application. For details, please refer to Figures 1 to 3 .

[0079] Based on the solution of the above embodiment 1:

[0080] Furthermore, if Figure 3 As shown, the driving assembly 2 includes a driving motor 21 , a motor gear 22 and a cleaning driving gear 23 .

[0081] The driving motor 21 is installed on the mechanism body 1, and its driving shaft 20 is fixedly connected to the motor gear 22 (it can be understood that the driving shaft 20 of the driving component 2 in the present application also refers to the driving shaft / output shaft of the driving motor 21); the cleaning driving gear 23 is rotatably installed on the mechanism body 1, and is fixed with a connecting shaft 24 for connecting the cleaning part; the motor gear 22 is transmission-connected to the cleaning driving gear 23.

[0082] The driving motor 21 drives the motor gear 22 to rotate, which in turn drives the cleaning driving gear 23 to rotate synchronously, and then drives the cleaning member to rotate through the connecting shaft 24. Figure 3 As shown, the motor gear 22 and the cleaning drive gear 23 are specifically installed in the installation cavity surrounded by the box shell 11 and the box cover 12, and the drive motor 21 is installed on the back side of the box shell 11 facing away from the box cover 12, and the connecting shaft 24 extends out of the back side of the box shell 11.

[0083] Furthermore, if Figure 3 As shown, the motor gear 22 is connected to the cleaning drive gear 23 through the transmission wheel set 25 to achieve the purpose of decelerating to increase the torque or accelerating to reduce the torque.

[0084] The transmission wheel assembly 25 includes a plurality of transmission gears 251 ; the plurality of transmission gears 251 are rotatably mounted on the mechanism body 1 , and the transmission gear 251 at the transmission start end meshes with the motor gear 22 , and the transmission gear 251 at the transmission end meshes with the cleaning drive gear 23 .

[0085] Taking the design of two transmission gears 251 as an example, the transmission gear 251 located at the starting position can be designed as a two-stage gear, which has a large gear and a small gear fixed coaxially, wherein the diameter of the large gear is larger than the motor gear 22 and meshes with the motor gear 22, and the diameter of the small gear is smaller than the diameter of the transmission gear 251 at the end position and meshes with the transmission gear 251 at the end. Technical personnel in this field can make changes to the design as needed, and there is no specific limitation.

[0086] Furthermore, if Figure 4 as well as Figure 5 As shown, the traction assembly 3 includes a traction rope 31 , a first input gear 32 , a first output member 33 and a first one-way transmission assembly 34 .

[0087] The first one-way transmission component 34 is installed on the mechanism body 1, and is connected to the first input gear 32 and the first output member 33, so as to construct a one-way gear mechanism. The one-way gear mechanism is a special gear mechanism. In one direction, the first one-way transmission component 34 can normally transmit the torque of the input gear to the output member, and in the opposite direction, it can disconnect the torque transmission between the input gear and the output member. There are several main ways to implement the one-way gear mechanism, such as a one-way overrunning clutch structure, a wedge-type one-way clutch structure, and a one-way ratchet structure. It can be understood that the first one-way transmission component 34 can be a one-way overrunning clutch component, a wedge-type one-way clutch component, and a one-way ratchet component.

[0088] The first one-way transmission component 34 of the present application is a one-way ratchet component, which specifically includes a fixed shaft, a first ratchet, a second ratchet and a spring, wherein the first ratchet is fixed to the fixed shaft, receives the torque of the first input gear 32 through the fixed shaft, the second ratchet is rotatably installed on the fixed shaft and is pressed by a spring to abut against the first ratchet, and a one-way tooth structure is provided between the first ratchet and the second ratchet, the one-way tooth structure meshes in one direction and slips against each other in the opposite direction to achieve torque transmission in one direction and disconnection of torque transmission in the opposite direction; since the one-way gear mechanism is an existing mechanism design, the present application does not elaborate on the specific structure of the first one-way transmission component 34.

[0089] The motor gear 22 or the cleaning drive gear 23 is drivingly connected to the first input gear 32. It can be understood that the motor gear 22 is directly meshed with the first input gear 32, or the cleaning drive gear 23 is directly meshed with the first input gear 32, and the details are not repeated.

[0090] like Figure 6 As shown, a fulcrum structure 14 is provided on the mechanism body 1 at one side of the first output member 33 ; one end of the traction rope 31 is connected to the first output member 33 , and the other end is passed through the fulcrum structure 14 and connected to the base 7 .

[0091] The traction rope 31 is a bendable metal rope with certain structural strength, and its two ends are designed to be quickly assembled with the base 7 and the first output member 33 by plug-in matching (for example, the two ends of the traction rope 31 are designed as plugs, and the base 7 and the first output member 33 are designed as slots for inserting the plugs, and there is no specific limitation), which is convenient for installation and disassembly and maintenance.

[0092] The fulcrum structure 14 is a cylindrical structure, which can be fixed on the mechanism body 1 or rotatably installed on the mechanism body 1 (the rotating design can play the role of a fixed pulley compared to the fixed design, and pulling the traction rope 31 is more labor-saving). By designing the fulcrum structure 14, it can be ensured that the first output member 33 can smoothly pull the traction rope 31 by rotating a certain range, and there is no need to achieve traction by winding the traction rope 31 around the first output member 33, thereby avoiding affecting the cooperation between the first output member 33 and the self-locking component 4.

[0093] When the driving shaft 20 of the driving assembly 2 rotates in the second direction, it can drive the first input gear 32 to rotate, and synchronously drive the first output member 33 to rotate through the first one-way transmission assembly 34 to pull the traction rope 31 .

[0094] In the present application, the first input gear 32 is installed in the installation cavity, the first one-way transmission component 34 is penetrated on the box shell 11, and the first output member 33 is installed on the back side of the box shell 11, wherein the first output member 33 can be a cam structure.

[0095] Furthermore, a guide groove 131 is provided on the mechanism body 1 , and the guide groove 131 is used to guide the traction rope 31 to improve the traction of the traction rope 31 .

[0096] Furthermore, if Figure 6 as well as Figure 7 As shown, the self-locking assembly 4 includes a locking member 41 and an elastic member 42 .

[0097] The locking member 41 is provided with a first locking portion 412 .

[0098] The lock member 41 is movably mounted on the mechanism body 1 in a direction close to or away from the first output member 33; specifically, Figure 6 As shown, a limiting groove 121 can be provided on the back of the mechanism body 1 (specifically the box shell 11) for the locking member 41 to be installed in a limited position. Figure 4 As shown, a limiting end cover 13 is provided, which is covered on the limiting groove 121 to prevent the locking member 41 from escaping from the limiting groove 121. Correspondingly, the guide groove 131 can be opened on the outer side of the limiting end cover 13.

[0099] The elastic member 42 connects the locking member 41 and the mechanism body 1 , and is used to provide a force for the locking member 41 to move in a direction close to the first output member 33 .

[0100] The first output member 33 is provided with a second locking portion 331 which is locked and connected to the first locking portion 412 .

[0101] Furthermore, if Figure 7As shown, the elastic member 42 is a compression spring, and the lock member 41 is provided with a positioning portion 411 for inserting one end of the compression spring. The positioning portion 411 is a columnar structure, which is convenient for positioning and installing the compression spring and improves the reliability of the compression movement of the positioning spring.

[0102] Furthermore, if Figure 7 As shown, the first locking portion 412 may be a protrusion, and correspondingly, the second locking portion 331 may be a groove for the protrusion to snap into. Of course, the first locking portion 412 may be a groove, and the second locking portion 331 may be a protrusion, and there is no specific limitation.

[0103] Furthermore, if Figures 1 to 3 As shown, the present application is also designed with an unlocking component 5 .

[0104] The unlocking assembly 5 is mounted on the mechanism body 1. When the driving shaft 20 of the driving assembly 2 rotates in the first direction, the unlocking assembly 5 can also be synchronously driven to move to release the locking of the traction assembly 3 by the self-locking assembly 4. It can be understood that while the cleaning assembly is normally driven to rotate, the unlocking assembly 5 can also be driven to move to complete the unlocking of the traction assembly 3 by the self-locking assembly 4, thereby ensuring that the next lifting movement can be locked normally.

[0105] Furthermore, if Figure 8 as well as Fig. 9 As shown, the unlocking assembly 5 includes a second input gear 51 , a second output member 52 and a second one-way transmission assembly 53 .

[0106] The second one-way transmission assembly 53 is installed on the mechanism body 1, and is connected to the second input gear 51 and the second output member 52, so as to construct a one-way gear mechanism. The one-way gear mechanism is a special gear mechanism. In one direction, the second one-way transmission assembly 53 can normally transmit the torque of the input gear to the output member, and in the opposite direction, it can disconnect the torque transmission between the input gear and the output member. There are several main ways to implement the one-way gear mechanism, such as a one-way overrunning clutch structure, a wedge-type one-way clutch structure, and a one-way ratchet structure. It can be understood that the second one-way transmission assembly 53 can be a one-way overrunning clutch assembly, a wedge-type one-way clutch assembly, and a one-way ratchet assembly.

[0107] In the present application, the second one-way transmission component 53 is a one-way ratchet component, which is consistent with the principle of the above-mentioned first one-way transmission component 34 and will not be described in detail.

[0108] For compact fit, the lock member 41 is provided with a central through cavity for accommodating the installation of the second one-way transmission assembly 53 ; and the second output member 52 is located in the central through cavity 413 .

[0109] When the driving shaft 20 of the driving assembly 2 rotates in the first direction, it can also synchronously drive the second input gear 51 to rotate, and synchronously drive the second output member 52 to rotate through the second one-way transmission assembly 53 .

[0110] The second output member 52 is provided with a pushing structure 521; when the second output member 52 rotates, the pushing structure 521 can contact the wall surface of the through cavity 413 facing the first output member 33, and push the locking member 41 to move away from the first output member 33, so as to release the locking connection between the locking member 41 and the first output member 33.

[0111] After being unlocked, the first output member 33 rotates and resets under the action of gravity of the cleaning component 6. It should be noted that, during the design, the first output member 33 can be designed to be able to contact and abut against the locking member 41 after rotation and reset, and the locking member 41 is placed in a position where the central through cavity 413 will not contact the pushing structure 521 on the rotating second output member 52, so that the second output member 52 remains in an idling state. In this way, the pushing structure 521 can be prevented from frequently contacting and pushing the locking member 41, which helps to reduce contact wear, while avoiding frequent compression movements of the elastic member 42 and extending the service life.

[0112] In the present application, the second input gear 51 is installed in the installation cavity, the second one-way transmission component 53 is installed on the box shell 11, and the second output member 52 is installed on the back side of the box shell 11, wherein the second output member 52 can be a cam structure (taking the cam structure as an example, the flange part on it also serves as the push structure 521). At the same time, the second input gear 51 is meshed with the first input gear 32 to achieve transmission connection.

[0113] The present application also discloses a cleaning device (the cleaning device may be a sweeping robot, a floor-holding robot, etc.), which includes the cleaning mechanism of the above-mentioned improved design.

[0114] The above is a detailed introduction to a cleaning mechanism and cleaning equipment provided by the present application. For a person skilled in the art, according to the idea of ​​the embodiments of the present application, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
