Description

Technical Field

[0001] This utility model relates to a swimming pool cleaning robot, and more particularly to a walking mechanism for a swimming pool cleaning robot. Background Technology

[0002] Pool cleaning robots are devices that can walk in swimming pools and remove foreign objects. They typically use motors to drive their wheels to move. Because underwater movement involves high resistance, the front and rear wheels must be synchronized to overcome this resistance. In existing pool cleaning robots, the front and rear wheels are connected by a belt. However, the friction surfaces of the belts can easily loosen and slip after prolonged use, leading to reduced transmission performance and low transmission efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a walking mechanism for a pool cleaning robot that has a reliable transmission relationship, is durable, and has high transmission efficiency, in order to address the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A walking mechanism for a pool cleaning robot includes a base shell, two front wheels symmetrically arranged on both sides of the base shell, and two rear wheels symmetrically arranged on both sides of the base shell. Gear assemblies are respectively provided on both sides of the base shell. Each gear assembly includes a front gear, a rear gear, and multiple intermediate gears. The multiple intermediate gears are kinetically connected between the front gear and the rear gear. The front gear is used to drive the front wheels to rotate, and the rear gear is used to drive the rear wheels to rotate. A motor for driving the gear assembly is provided inside the base shell.

[0006] Preferably, the bottom shell contains two motors, which are respectively driven by two rear gears.

[0007] Preferably, the drive shaft of the motor is provided with a drive gear, which meshes with the rear gear.

[0008] Preferably, the front wheel has a front gear disk on its side, and the front gear meshes with the front gear disk.

[0009] Preferably, the rear wheel has a rear gear disk on its side, and the rear gear meshes with the rear gear disk.

[0010] Preferably, the side of the bottom shell is provided with a front wheel axle and a rear wheel axle, the front wheel is sleeved on the front wheel axle and the two are rotatably engaged, and the rear wheel is sleeved on the rear wheel axle and the two are rotatably engaged.

[0011] Preferably, the bottom shell is provided with a roller brush drive gear and a roller brush drive gear on both sides. The two roller brush drive gears are coaxially connected to both ends of the roller brush, and the roller brush drive gear meshes between the roller brush drive gear and the front gear disk.

[0012] In the walking mechanism of the pool cleaning robot disclosed in this utility model, two front wheels and two rear wheels are symmetrically arranged on the outer side of the bottom shell. On the same side of the bottom shell, the front wheels and the rear wheels are connected by a gear assembly. The rear gear in the gear assembly is driven by the motor, and the front gear and the rear gear drive the front wheels and the rear wheels respectively. The front gear and the rear gear are connected by multiple intermediate gears in sequence. When the motor is running, based on the transmission action of the gear assembly, the front wheels and the rear wheels can be driven to run synchronously, thereby realizing the walking drive and transmission functions. Compared with the belt drive method in the prior art, the transmission relationship of this utility model is reliable and durable, can overcome greater water resistance, and has higher transmission efficiency.

[0017] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0018] This utility model discloses a walking mechanism for a pool cleaning robot, combined with Figures 1 to 4 As shown, it includes a base shell 1, two front wheels 2 symmetrically arranged on both sides of the base shell 1, and two rear wheels 3 symmetrically arranged on both sides of the base shell 1. Gear assemblies 10 are respectively provided on both sides of the base shell 1. The gear assembly 10 includes a front gear 4, a rear gear 5, and multiple intermediate gears 6. The multiple intermediate gears 6 are kinetically connected between the front gear 4 and the rear gear 5. The front gear 4 is used to drive the front wheels 2 to rotate, and the rear gear 5 is used to drive the rear wheels 3 to rotate. A motor 7 is provided inside the base shell 1 to drive the gear assembly 10 to rotate.

[0019] In the above structure, two front wheels 2 and two rear wheels 3 are symmetrically arranged on the outer side of the bottom shell 1. On the same side of the bottom shell 1, the front wheels 2 and the rear wheels 3 are connected by a gear assembly 10. The rear gear 5 in the gear assembly 10 is driven by the motor 7. The front gear 4 and the rear gear 5 drive the front wheels 2 and the rear wheels 3 to rotate, respectively. The front gear 4 and the rear gear 5 are connected by multiple intermediate gears 6 in sequence. When the motor 7 is running, based on the transmission action of the gear assembly 10, the front wheels 2 and the rear wheels 3 can be driven to rotate synchronously, thereby realizing the walking drive and transmission functions. Compared with the belt drive method in the prior art, the transmission relationship of this utility model is reliable and durable, can overcome greater water resistance, and has higher transmission efficiency.

[0020] As a preferred embodiment, the bottom shell 1 is equipped with two motors 7, which are respectively driven by two rear gears 5. In this embodiment, the two motors 7 drive the wheels on the left and right sides of the bottom shell 1 to rotate. In practical applications, differential speed control of the two motors 7 is sufficient to achieve rotational and other walking control. In addition, forward and backward control can also be achieved by controlling the two motors 7 to rotate in both directions.

[0021] For the preferred transmission method between the motor 7 and the rear gear 5, please refer to [link / reference]. Figure 1 and Figure 2 In this embodiment, the drive shaft of the motor 7 is provided with a drive gear 8, which meshes between the rear gear 5 and the intermediate gear 6, and drives the rear gear 5 and the intermediate gear 6 to operate synchronously.

[0022] In order to effectively drive the front and rear wheels, please refer to the following embodiment: Figure 3 and Figure 4 The front wheel 2 has a front gear disk 20 on its side, and the front gear 4 meshes with the front gear disk 20. Similarly, the rear wheel 3 has a rear gear disk 30 on its side, and the rear gear 5 meshes with the rear gear disk 30.

[0023] In a preferred embodiment, the side of the base shell 1 is provided with a front axle 11 and a rear axle 12. The front wheel 2 is fitted onto the front axle 11 and the two are rotatably engaged, and the rear wheel 3 is fitted onto the rear axle 12 and the two are rotatably engaged. The front axle 11 and the rear axle 12 not only support the front wheel 2 and the rear wheel 3, but also ensure reliable rotation of the front wheel 2 and the rear wheel 3.

[0024] To achieve the foreign object cleaning function, please refer to the following in this embodiment: Figure 1 and Figure 2The bottom shell 1 has a roller brush 13 at its front end, and roller brush drive gears 15 and roller brush drive gears 14 on both sides of the bottom shell 1. The two roller brush drive gears 14 are coaxially connected to both ends of the roller brush 13, and the roller brush drive gears 15 mesh between the roller brush drive gears 14 and the front gear disk 20. Specifically, the roller brush 13 can clean foreign objects in the pool into the robot's receiving compartment during operation.

[0025] In the above structure, by setting roller brush drive gears 15 on both sides of the bottom shell 1, the front wheel 2 can drive the roller brush drive gear 15 and roller brush drive gear 14 to rotate through the front gear disk 20 during the walking process, which further drives the roller brush 13 to rotate. There is no need to configure a separate power mechanism for the roller brush 13, which simplifies the product structure and saves internal space.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
