Description

Technical Field

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

[0002] Cleaning equipment includes sweeping robots, vacuum cleaners, and multi-functional cleaning base stations. Most cleaning equipment is often equipped with a middle sweeping component, which is used to clean external garbage and collect it into the cleaning equipment.

[0003] However, existing power transmission systems for mid-sweep assemblies mostly rely on rigid connections, such as directly connecting the power source to the mid-sweep assembly's rotating shaft via rigid components like couplings and bushings. This rigid transmission method can easily cause resonance in the mid-sweep assembly during operation, resulting in high noise levels and severely impacting its stability. Summary of the Invention

[0004] The main purpose of the present application is to provide a middle sweep mechanism and a cleaning device to solve the problem in the prior art that the middle sweep assembly adopts a rigid transmission, which causes the middle sweep assembly to generate resonance and noise during operation.

[0009] Furthermore, the elastic component includes an elastic member, and the elastic member is connected between the driving assembly and the cleaning assembly through a locking member and / or a first clamping portion.

[0010] Furthermore, the cleaning assembly includes a rotating shaft, and the cleaning assembly is rotatably disposed in the accommodating cavity via the rotating shaft;

[0011] The elastic member includes an elastic sleeve, which is sleeved on the rotating shaft and connected to the rotating shaft through the locking member. The elastic sleeve is provided with the first clamping portion, and the elastic sleeve is connected to the driving assembly through the first clamping portion.

[0012] Furthermore, the elastic sleeve includes an annular sleeve body and an inner flange, and the inner flange is located on a side of the annular sleeve body close to the rotating shaft;

[0013] Wherein, a flat portion is provided at one end of the rotating shaft close to the driving assembly, a through hole adapted to the flat portion is provided on the inner flange, the inner flange is sleeved on the flat portion through the through hole, and is connected to the rotating shaft through the locking member; and / or,

[0014] The first clamping portion is provided on a side of the annular sleeve away from the inner flange, and the annular sleeve is clamped to the driving assembly through the first clamping portion.

[0015] Furthermore, the driving assembly includes a power output member, one end of the power output member close to the cleaning assembly is inserted into the annular sleeve, and the outer surface of the power output member is provided with a second clamping portion that cooperates with the first clamping portion.

[0016] Furthermore, the outer surface of the rotating shaft is sleeved with a bearing component, and the bearing component includes a sleeve and a bearing, the sleeve is sleeved on the rotating shaft, and the bearing is sleeved on the sleeve and located on the side of the elastic member;

[0017] The locking member includes a locking screw, which is detachably connected to the flat portion along the axial direction of the rotating shaft and locks the inner flange to the end surface of the sleeve.

[0018] Furthermore, the shaft sleeve has a protective groove, an annular boss is provided in the protective groove, and the elastic sleeve is located in the protective groove. When the locking screw locks the elastic sleeve on the shaft sleeve, the elastic sleeve abuts against the annular boss.

[0019] Furthermore, at least one strip-shaped hollow is provided on the elastic member, and the strip-shaped hollow extends along the circumference of the elastic member.

[0020] Furthermore, the elastic sleeve comprises a metal sleeve, and the inner flange is provided with a plurality of first arc-shaped openings spaced apart along the outer circumference of the through hole, and each of the first arc-shaped openings protrudes in a direction away from the through hole;

[0021] A plurality of second arc-shaped openings are provided at the junction of the inner flange and the annular sleeve.

At the same time, since an elastic component is provided between the cleaning component and the drive component of the present application, when the drive component drives the cleaning component to rotate, the elastic component can rely on its own elastic deformation to buffer the impact force during the transmission process, effectively reducing vibration and reducing the possibility of resonance. It is worth mentioning that since the elastic component of the present application can undergo torsional deformation along the rotation direction of the cleaning component, this further optimizes the buffering effect. When the cleaning component is unevenly stressed or the rotation direction changes instantaneously, the elastic component can quickly absorb and disperse stress through torsional deformation, avoiding local overload. At the same time, the provision of the elastic component reduces the rigid collision between the cleaning component and the drive component, thereby reducing the operating noise of the cleaning component and making the operation of the middle sweep mechanism more stable. In addition, the elastic component can also compensate for the installation error and motion error between the cleaning component and the drive component to a certain extent, effectively improving the reliability and stability of the operation of the middle sweep mechanism and extending the service life of the middle sweep mechanism.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0034] As mentioned in the background, most existing sweep assemblies utilize a rigid transmission system for power transmission. This rigid transmission system can easily cause resonance and noise generation during operation, seriously impacting the stability of the sweep assembly. To address this issue, the inventors of this application have designed a novel sweep mechanism that addresses the resonance and noise generation issues associated with the rigid transmission system used in existing sweep assemblies. The present sweep mechanism is described in detail below with reference to the accompanying drawings.

[0035] See also Figures 1 to 4 As shown, the present application provides a middle sweeping mechanism, which includes a housing 10 , a cleaning assembly 20 , a driving assembly 30 and an elastic component 40 .

[0036] The housing 10 has a receiving chamber 101; the cleaning assembly 20 is rotatably disposed in the receiving chamber 101; and the elastic member 40 is disposed between the cleaning assembly 20 and the driving assembly 30. Driven by the driving assembly 30, the elastic member 40 drives the cleaning assembly 20 to rotate about its own axis, and the elastic member 40 can be torsional deformed along the rotation direction of the cleaning assembly 20. For example, the cleaning assembly 20 in this embodiment can be a roller brush, or a roller and a mop.

[0037] In this embodiment, the accommodating cavity 101 can provide a stable and protected installation space for the cleaning assembly 20. When the middle sweep mechanism of this embodiment is installed on the cleaning equipment, the rotation of the cleaning assembly 20 can be used to sweep away garbage on the surface to be cleaned. At the same time, because the elastic component 40 is provided between the cleaning assembly 20 and the drive assembly 30 in this embodiment, when the drive assembly 30 drives the cleaning assembly 20 to rotate, the elastic component 40 can use its own elastic deformation to buffer the impact force during the transmission process, effectively reducing vibration and lowering the possibility of resonance. It is worth mentioning that because the elastic component 40 in this embodiment can undergo torsional deformation along the rotation direction of the cleaning assembly 20, this further optimizes the buffering effect. When the cleaning assembly 20 is subjected to uneven force or the rotation direction changes instantaneously, the elastic component 40 can quickly absorb and disperse the stress through torsional deformation, avoiding local overload. At the same time, the provision of the elastic component 40 reduces the rigid collision between the cleaning assembly 20 and the drive assembly 30, thereby reducing the operating noise of the cleaning assembly 20 and making the middle sweep mechanism operate more smoothly. In addition, the elastic component 40 can also compensate for the installation error and motion error between the cleaning component 20 and the driving component 30 to a certain extent, effectively improving the reliability and stability of the operation of the middle sweeping mechanism and extending the service life of the middle sweeping mechanism.

[0038] Further, see Figure 2As shown, the elastic member 40 in this embodiment includes an elastic member 41, and the elastic member 41 is connected between the driving assembly 30 and the cleaning assembly 20 through the locking member 50 and / or the first clamping portion 60. In other words, the elastic member 41 in this embodiment can be connected between the driving assembly 30 and the cleaning assembly 20 only through the locking member 50, or can be connected between the driving assembly 30 and the cleaning assembly 20 only through the first clamping portion 60, or can be connected between the driving assembly 30 and the cleaning assembly 20 through the locking member 50 and the first clamping portion 60.

[0039] Specifically, the locking member 50 provides a reliable fixing effect, ensuring that the elastic member 41 will not easily loosen or fall off during the transmission process, thereby ensuring the stability of the operation of the mid-sweeping mechanism; the first clamping portion 60 facilitates the rapid installation and removal of the elastic member 41. When maintaining or replacing the elastic member 41, it can be completed without complex tools and operations, greatly improving maintenance efficiency; and the combination of the locking member 50 and the first clamping portion 60 not only ensures the firmness of the connection, but also enhances the convenience of installation and removal. At the same time, the elastic member 41 itself has good buffering properties. In conjunction with the above-mentioned connection method, it can better absorb the vibration and impact force during the rotation of the driving assembly 30 driving the cleaning assembly 20, further reducing resonance and noise, and extending the service life of each component.

[0040] Further, see Figures 2 to 3 As shown, the cleaning assembly 20 in this embodiment includes a rotating shaft 21, and the cleaning assembly 20 is rotatably arranged in the accommodating cavity 101 through the rotating shaft 21; the elastic member 41 includes an elastic sleeve 42, the elastic sleeve 42 is sleeved on the rotating shaft 21 and is connected to the rotating shaft 21 through a locking member 50, and a first clamping portion 60 is provided on the elastic sleeve 42, and the elastic sleeve 42 is connected to the driving assembly 30 through the first clamping portion 60.

[0041] Specifically, the rotating shaft 21 in this embodiment provides a rotational axis for the cleaning assembly 20, allowing the cleaning assembly 20 to rotate stably within the accommodating chamber 101 to complete the cleaning task; the elastic sleeve 42 is mounted on the rotating shaft 21, which can precisely apply the elastic buffering function to the rotating core of the cleaning assembly 20, effectively absorbing the vibration generated during rotation. At the same time, this embodiment connects the elastic sleeve 42 to the rotating shaft 21 through a locking member 50, which can ensure the stability of the connection between the elastic sleeve 42 and the rotating shaft 21 and avoid affecting the buffering effect due to looseness; and the elastic sleeve 42 is connected to the drive assembly 30 through a first clamping portion 60, which simplifies the connection structure and enables quick assembly of the elastic sleeve 42 and the drive assembly 30. This connection method not only ensures the stability of the transmission of the mid-sweeping mechanism, but also further reduces resonance and noise, thereby improving the stability and reliability of the mid-sweeping mechanism.

[0042] Further, see Figures 2 to 3As shown, the elastic sleeve 42 in this embodiment includes an annular sleeve body 421 and an inner flange 422, and the inner flange 422 is located on the side of the annular sleeve body 421 close to the rotating shaft 21; wherein, a flat portion 211 is provided at one end of the rotating shaft 21 close to the driving assembly 30, and a through hole 423 adapted to the flat portion 211 is provided on the inner flange 422, and the inner flange 422 is sleeved on the flat portion 211 through the through hole 423, and is connected to the rotating shaft 21 through a locking member 50.

[0043] Specifically, the arrangement of the annular sleeve 421 and the inner flange 422 not only imparts excellent elastic cushioning properties to the elastic sleeve 42, but also provides a reliable structural foundation for the connection between the elastic sleeve 42 and the rotating shaft 21. Specifically, because the flat portion 211 of the rotating shaft 21 mates with the through-hole 423 on the inner flange 422, a precise positioning and limiting structure is formed, preventing the elastic sleeve 42 from idling around the rotating shaft 21 during transmission, ensuring that the power of the drive assembly 30 is stably and efficiently transmitted to the cleaning assembly 20. Furthermore, this embodiment further reinforces the connection through the locking member 50, enhancing structural stability and preventing the elastic sleeve 42 from loosening with the rotating shaft 21 due to vibration during operation of the mid-sweeping mechanism.

[0044] Further, see Figures 3 and 4 As shown, a first clamping portion 60 is provided on the side of the annular sleeve 421 facing away from the inner flange 422 in this embodiment, and the annular sleeve 421 is clamped to the driving assembly 30 through the first clamping portion 60 .

[0045] Specifically, the first clamping portion 60 enables rapid assembly of the annular sleeve 421 and the drive assembly 30. Compared with traditional screw fastening methods, it greatly shortens installation time, reduces assembly difficulty, and facilitates batch assembly during the production process. The clamping structure itself has a certain elastic matching space. During the operation of the middle sweep mechanism, it can allow for slight displacement compensation between the annular sleeve 421 and the drive assembly 30, effectively alleviating stress concentration caused by manufacturing errors, thermal expansion and contraction, and further enhancing the reliability of the middle sweep mechanism. At the same time, this connection method makes the elastic sleeve 42 more flexible and efficient in buffering vibrations and absorbing impact forces. Combined with the elastic deformation of the elastic sleeve 42 itself, it suppresses resonance in all directions, significantly reduces operating noise, and ensures the smooth operation of the middle sweep mechanism.

[0046] Further, see Figure 2 as well as Figure 4 As shown, the driving assembly 30 in this embodiment includes a power output member 31, and one end of the power output member 31 close to the cleaning assembly 20 is inserted into the annular sleeve 421, and the outer surface of the power output member 31 is provided with a second clamping portion 70 that cooperates with the first clamping portion 60.

[0047] Specifically, because the power output member 31 in this embodiment is inserted within the annular sleeve 421, the power transmission path is shortened, making power transfer more direct and efficient. The second engaging portion 70 on the outer surface of the power output member 31 cooperates with the first engaging portion 60 of the elastic sleeve 42 to form a secure and stable engagement structure, effectively preventing the power output member 31 from separating from the elastic sleeve 42 during operation and ensuring stable power transmission. Furthermore, the arrangement of the first engaging portion 60 and the second engaging portion 70 facilitates quick assembly and disassembly of the drive assembly 30 and the elastic sleeve 42, facilitating installation, commissioning, and subsequent maintenance of the mid-sweep mechanism, thereby improving its maintainability.

[0048] Further, see Figure 1 As shown, the drive assembly 30 in this embodiment also includes a drive motor 32, a gearbox 33, and a power output fitting 34. The output shaft of the drive motor 32 is connected to the gear set within the gearbox 33, and the power output fitting 34 is connected between the gearbox 33 and the power output member 31. The drive motor 32 drives the gear set within the gearbox 33 to rotate, thereby driving the power output fitting 34 to rotate, which in turn drives the power output member 31 to rotate, and further drives the rotating shaft 21 to rotate via the elastic sleeve 42, thereby driving the cleaning assembly 20 to rotate. For example, in this embodiment, the power output fitting 34 and the power output member 31 are connected together by a key connection.

[0049] Further, see Figures 3 and 4 As shown in FIG. 1 , one of the first clamping portion 60 and the second clamping portion 70 in this embodiment is a clamping protrusion 61, and the other is a clamping groove 71. It is understandable that when the first clamping portion 60 is configured as the clamping protrusion 61, the second clamping portion 70 is configured as the clamping groove 71; when the first clamping portion 60 is configured as the clamping groove 71, the second clamping portion 70 is configured as the clamping protrusion 61. Figure 3 The first clamping portion 60 is shown as a clamping protrusion 61. Figure 4 The figure shows a situation where the second clamping portion 70 is configured as a clamping groove 71 .

[0050] Specifically, the first clamping portion 60 and the second clamping portion 70 adopt a convex and concave clamping structure, which can achieve a tight connection between the drive assembly 30 and the elastic sleeve 42. During installation, it is only necessary to embed the clamping protrusion 61 into the clamping groove 71 to quickly complete the assembly without the need for complex tools and tedious operations, which significantly improves assembly efficiency. During operation, the clamping protrusion 61 and the clamping groove 71 fit together, which can effectively limit the relative displacement between the components, ensure the stable transmission of the power of the power output member 31 to the elastic sleeve 42 and the cleaning assembly 20, and avoid transmission failure caused by loose connection. At the same time, the concave and convex clamping structure allows a certain degree of elastic deformation during the power transmission process, which can buffer the instantaneous impact force during power transmission, absorb vibration energy, further suppress resonance, and reduce operating noise.

[0051] Further, see Figure 2 As shown, the outer surface of the rotating shaft 21 in this embodiment is sleeved with a bearing component 80, which includes a sleeve 81 and a bearing 82. The sleeve 81 is sleeved on the rotating shaft 21, and the bearing 82 is sleeved on the sleeve 81 and located on the side of the elastic member 41. The locking member 50 includes a locking screw 51, which is detachably connected to the flat portion 211 along the axial direction of the rotating shaft 21 and locks the inner flange 422 to the end surface of the sleeve 81. Of course, in other embodiments of the present application, the locking member 50 can also be configured as a pin, a circlip, or a key connection structure. As long as other variations are based on the concept of this application, they are within the scope of protection of this application.

[0052] Specifically, the shaft sleeve 81 provides preliminary support and protection for the rotating shaft 21, reducing the direct friction between the rotating shaft 21 and other components; the setting of the bearing 82 can reduce the resistance of the cleaning component 20 during rotation, so that the cleaning component 20 can rotate more smoothly around its own axis, improve rotation efficiency, and reduce energy loss; and the use of the locking screw 51 as the locking member 50 can effectively prevent the elastic member 41 from axial movement or loosening during the transmission process, ensuring that the elastic member 41 stably transmits power and buffers vibration.

[0053] Further, see Figure 2 As shown, the shaft sleeve 81 in this embodiment has a protective groove 811, and an annular boss 812 is provided in the protective groove 811. The elastic sleeve 42 is located in the protective groove 811. When the locking screw 51 locks the elastic sleeve 42 on the shaft sleeve 81, the elastic sleeve 42 abuts against the annular boss 812.

[0054] Specifically, the protective groove 811 protects the elastic sleeve 42 from damage due to external impact or friction. The annular boss 812 defines the axial position of the elastic sleeve 42. When the locking screw 51 locks the elastic sleeve 42, the elastic sleeve 42 abuts against the annular boss 812, preventing axial displacement of the elastic sleeve 42 and ensuring the assembly accuracy and stability of the entire mechanism.

[0055] Further, see Figure 3 As shown, the elastic member 41 in this embodiment is provided with at least one strip-shaped hollow 90, and the strip-shaped hollow 90 extends along the circumference of the elastic member 41. For example, the strip-shaped hollow 90 in this embodiment can be provided as one, or as two, or more than one, and this application does not specifically limit this. It is understood that the strip-shaped hollow 90 in this embodiment can be a linear gap or an arc-shaped gap.

[0056] Specifically, the provision of the strip-shaped hollow 90 makes the structure of the elastic member 41 more flexible, allowing it to deform more easily when subjected to external forces, thereby enhancing the elasticity and flexibility of the elastic member 41. Furthermore, by removing some material from the elastic member 41 to form the strip-shaped hollow 90, this embodiment effectively reduces the weight of the elastic member 41 without affecting its basic function.

[0057] Further, see Figure 3 As shown, the elastic sleeve 42 in this embodiment comprises a metal sleeve. The inner flange 422 is provided with a plurality of first arcuate openings 91 spaced apart along the periphery of the through hole 423. Each first arcuate opening 91 protrudes in a direction away from the through hole 423. A plurality of second arcuate openings 92 are provided at the junction of the inner flange 422 and the annular sleeve body 421. The plurality of second arcuate openings 92 are spaced apart along the periphery of the through hole 423. Each second arcuate opening 92 protrudes in a direction away from the through hole 423. For example, the elastic sleeve 42 in this embodiment comprises a spring steel sleeve.

[0058] It should be noted that, in this embodiment, “the first arc-shaped opening 91 protrudes in a direction away from the through hole 423” means: with the center of the through hole 423 as a reference, the arc-shaped edge of the first arc-shaped opening 91 protrudes outward; and “the second arc-shaped opening 92 protrudes in a direction away from the through hole 423” means: with the center of the through hole 423 as a reference, the arc-shaped edge of the second arc-shaped opening 92 protrudes outward.

[0059] Specifically, the metal sleeve itself has a certain strength and elasticity, and the design of the first arc-shaped opening 91 and the second arc-shaped opening 92 makes the structure of the inner flange 422 and the annular sleeve body 421 more flexible. These arc-shaped openings can produce elastic deformation when subjected to external force, thereby further enhancing the elasticity and flexibility of the elastic sleeve 42, enabling it to better adapt to different working conditions, effectively buffering the impact and vibration during power transmission, and protecting the components connected to it. At the same time, multiple arc-shaped openings are arranged at intervals along the outer periphery of the through hole 423, so that when the elastic sleeve 42 is subjected to force, the force can be more evenly distributed over the entire structure, avoiding stress concentration. In particular, the second arc-shaped opening 92 provided at the junction can effectively alleviate the stress concentration phenomenon at the connection between the inner flange 422 and the annular sleeve body 421, reduce the risk of fatigue damage to the components due to excessive local stress, and improve the service life and reliability of the elastic sleeve 42. In addition, by providing the first arc-shaped opening 91 and the second arc-shaped opening 92 , part of the material can be removed, which effectively reduces the weight of the elastic sleeve 42 while ensuring the basic performance of the elastic sleeve 42 , reduces the amount of material used, and reduces production costs.

[0060] On the other hand, the embodiment of the present application further provides a cleaning device, which includes the above-mentioned middle sweeping mechanism, and thus the cleaning device includes all the technical effects of the above-mentioned middle sweeping mechanism. Since the technical effects of the middle sweeping mechanism have been described in detail above, they will not be repeated here.

[0061] Specifically, the cleaning device in this embodiment further includes a main body (not shown in the drawings), and a middle sweeping mechanism is provided at the bottom of the main body.

[0062] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. 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 figures. For example, if the device in the 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.

[0063] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
