Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a universal wheel mechanism and a cleaning robot. Background Technology

[0002] A cleaning robot is a smart home device that combines artificial intelligence and the Internet of Things (IoT) technologies. It cleans floors through autonomous navigation, environmental perception, and intelligent algorithms. Its core functions include automatic sweeping, obstacle avoidance, path planning, and remote control, enabling it to efficiently remove dust, hair, debris, and other trash from indoor and outdoor areas.

[0003] Currently, cleaning robots move using casters when operating autonomously. However, in existing technologies, debris easily gets tangled around the axle of the casters, affecting their normal use. Furthermore, the large gap between the caster body and the bearing allows dust, hair, and other debris to easily enter and become entangled in the bearing, increasing the resistance to wheel rotation and causing accelerated bearing wear, thus affecting the lifespan of the casters. Utility Model Content

[0004] The purpose of this utility model is to provide a universal wheel mechanism and a cleaning robot to solve the problem that in the prior art, the pivot position of the universal wheel is easily entangled with debris, which affects the normal use of the universal wheel. In addition, dust, hair and other debris can easily enter and get entangled on the bearing, which not only increases the resistance of the wheel rotation, but also leads to accelerated bearing wear and affects the service life of the universal wheel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] On the one hand, this utility model provides a universal wheel mechanism, including:

[0007] A wheel frame having two opposing support plates;

[0008] A wheelset, comprising a shaft, a bearing assembly, and a wheel body, wherein the bearing assembly is fitted over the shaft, and the wheel body is fitted over the bearing assembly; both end faces of the wheel body are provided with grooves, and both ends of the shaft pass through the two grooves respectively and are connected to the two support plates;

[0009] An anti-tangle cover is fixedly sleeved on the outside of the rotating shaft; the anti-tangle cover includes two covers, which are respectively disposed at opposite ends of the wheel body, and the outer periphery of the anti-tangle cover can be embedded in the groove.

[0010] As an alternative to the aforementioned caster wheel mechanism, the caster wheel mechanism further includes a brush component, which is disposed on the anti-tangle cover and is used to brush the groove wall of the groove.

[0011] As an alternative to the aforementioned caster wheel mechanism, the brush component includes a plurality of bristles, which are evenly arranged along the outer periphery of the anti-tangle cover.

[0012] As an alternative to the aforementioned caster wheel mechanism, the anti-tangle cover is arranged in an arc shape from the middle part to the outer periphery, and the middle part of the anti-tangle cover abuts against the support plate.

[0013] As an alternative to the aforementioned swivel wheel mechanism, the wheel set also includes a tire, which is fitted onto the wheel body.

[0014] As an alternative to the aforementioned caster wheel mechanism, the pivot is a fixing bolt, and the caster wheel mechanism also includes a fixing nut, wherein the fixing bolt passes through the two support plates and is threaded to the fixing nut.

[0015] As an alternative to the aforementioned caster wheel mechanism, the caster wheel mechanism further includes a connecting plate, and the wheel frame is rotatably connected to the lower surface of the connecting plate.

[0016] As an alternative to the aforementioned caster wheel mechanism, the connecting plate has several mounting holes on its outer periphery.

[0017] As an alternative to the aforementioned caster wheel mechanism, the mounting hole is a waist hole.

[0018] On the other hand, this utility model provides a cleaning robot, including the omnidirectional wheel mechanism as described above.

[0019] The beneficial effects of this utility model are as follows:

[0020] The swivel wheel mechanism includes a wheel frame, wheel assembly, and anti-winding covers. The wheel frame has two opposing support plates. The wheel assembly includes a shaft, bearing components, and a wheel body. The bearing components are fitted over the shaft, and the wheel body is fitted over the bearing components. Grooves are formed on both end faces of the wheel body. The two ends of the shaft pass through the two grooves and connect to the two support plates, allowing the wheel body to rotate relative to the wheel frame. The bearing components improve the load-bearing capacity and smoothness of movement of the swivel wheel mechanism. Two anti-winding covers are fixedly fitted over the shaft, located at opposite ends of the wheel body. The outer circumference of the anti-winding covers can be embedded in the grooves. This nested fit between the anti-winding covers and the grooves on the wheel body prevents debris from entangled on the shaft and prevents dust, hair, and other debris from entering the wheel body and causing wear on the bearing components, thus extending the service life of the swivel wheel mechanism.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] like Figure 1 As shown, this embodiment provides a caster wheel mechanism that can move on the ground.

[0029] The swivel wheel mechanism includes a wheel frame 1, a wheel assembly 2, and an anti-winding cover 3. The wheel frame 1 has two opposing support plates 11. The wheel assembly 2 includes a rotating shaft 21, bearing components, and a wheel body 22. The bearing components are sleeved on the rotating shaft 21, and the wheel body 22 is sleeved on the bearing components. Both end faces of the wheel body 22 have grooves 221. The two ends of the rotating shaft 21 pass through the two grooves 221 and are connected to the two support plates 11, thereby allowing the wheel body 22 to rotate relative to the wheel frame 1. The bearing components improve the load-bearing capacity and smoothness of movement of the swivel wheel mechanism. Optionally, the wheel assembly 2 also includes a tire 23, which is sleeved on the wheel body 22. The tire 23 prevents the wheel body 22 from slipping relative to the ground and also provides noise reduction and shock absorption.

[0030] Among them, the anti-winding cover 3 is fixedly sleeved on the outside of the rotating shaft 21. There are two anti-winding covers 3, which are respectively located at opposite ends of the wheel body 22. The outer periphery of the anti-winding cover 3 can be embedded in the groove 221. Thus, through the nesting cooperation between the anti-winding cover 3 and the groove 221 on the wheel body 22, it is possible to prevent debris from winding around the rotating shaft 21 and prevent dust, hair and other debris from entering the interior of the wheel body 22, which would cause wear on the bearing components, thereby extending the service life of the universal wheel mechanism.

[0031] Furthermore, the swivel wheel mechanism also includes a brush component 4, which is mounted on the anti-tangle cover 3 and used to brush the groove wall of the groove 221. The brush component 4 prevents dust, hair, and other debris from entering the wheel body 22 through the gap between the anti-tangle cover 3 and the groove 221 after prolonged use, thus avoiding interference with the swivel wheel mechanism. Specifically, the brush component 4 includes several bristles, which are evenly distributed along the outer periphery of the anti-tangle cover 3. These bristles not only brush the groove wall of the groove 221 but also block dust, hair, and other debris, further enhancing the barrier effect.

[0032] Furthermore, the anti-winding cover 3 is arranged in an arc shape from the middle part to the outer periphery, and the middle part of the anti-winding cover 3 abuts against the support plate 11, so that the anti-winding cover 3 can guide dust, hair and other debris, thereby further improving the anti-winding performance of the caster mechanism.

[0033] Furthermore, the rotating shaft 21 is a fixing bolt, and the universal wheel mechanism also includes a fixing nut 5. The fixing bolt passes through the two support plates 11 and is threaded to the fixing nut 5, which facilitates the production and installation of the universal wheel mechanism. At the same time, after the fixing nut 5 is removed from the fixing bolt, it is also convenient to maintain the universal wheel mechanism.

[0034] Furthermore, the caster wheel mechanism also includes a connecting plate 6, with the wheel frame 1 rotatably connected to the lower surface of the connecting plate 6. This allows the caster wheel mechanism to move in any direction by rotating the wheel frame 1 relative to the connecting plate 6. Simultaneously, the connecting plate 6 has several mounting holes 61 on its outer periphery, allowing the caster wheel mechanism to be mounted on mobile devices such as cleaning robots. Optionally, the mounting holes 61 are recessed holes, providing greater adjustment space during installation and making the installation process more flexible.

[0035] This embodiment also provides a cleaning robot, including the aforementioned omnidirectional wheel mechanism. By using the aforementioned omnidirectional wheel mechanism, the cleaning robot can move on the ground. The omnidirectional wheel mechanism has a long service life and can prevent debris from getting tangled and affecting its movement.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
