Description

Technical Field

[0001] This utility model relates to a drive mechanism for a swimming pool robot, belonging to the field of smart home technology. Background Technology

[0002] With the continuous advancement of automation technology, robots have gradually integrated into people's daily lives. Pool cleaning robots, as intelligent devices specifically designed to meet pool cleaning needs, can automatically and repeatedly clean the pool bottom and walls, and also have water filtration capabilities. During operation, these robots typically rely on the rotation of brush rollers to remove dirt from the pool surface. However, the drive methods for the brush rollers in currently available pool cleaning robots have certain limitations—some products use independent motors, which, while providing stable power, are more expensive; others use wheels to drive the brush rollers, a design that limits the roller speed to the robot's movement speed, resulting in less than ideal cleaning effects. Therefore, it is necessary to design a new power output structure to improve the working efficiency and cleaning capabilities of pool cleaning robots. Utility Model Content

[0003] The purpose of this invention is to overcome the problems existing in the prior art and provide a drive mechanism for a pool robot, which drives the travel gear through the roller brush gear, so that the rotation speed of the roller brush is not affected by the robot's movement speed.

[0004] To solve the above technical problems, this utility model provides a driving mechanism for a swimming pool robot. The driving mechanism is symmetrically arranged on both sides of the housing and includes: a motor disposed inside the housing and a travel gear located on the front side of the housing. The characteristic is that: the rotor shaft of the motor extends out of the housing and a motor gear is installed at its outer end; a roller brush gear is installed at one end of the roller brush shaft; the motor gear drives and connects to the roller brush gear; and the roller brush gear is driven and connected to the internal gear ring of the travel gear.

[0005] Furthermore, the roller brush gear includes an inner tooth section and an outer tooth section, the motor gear meshes with the bridge gear, the bridge gear meshes with the inner tooth section of the roller brush gear, and the outer tooth end of the roller brush gear meshes with the inner gear ring of the traveling gear.

[0006] Furthermore, the outer gear ring of the traveling gear meshes with the inner teeth of the track, and the other end of the track is fitted onto the outer circumference of the driven wheel.

[0007] Furthermore, the bridge gear is coaxially arranged with the traveling wheel.

[0008] Furthermore, the traveling gear rotates in the same direction as the brush gear.

[0009] Furthermore, the roller brush is located on the front side of the housing.

[0010] Compared to existing technologies, this invention achieves the following beneficial effects: By using a roller brush gear to drive a traveling gear for transmission, the rotational speed of the roller brush is not affected by the robot's traveling speed, thereby improving cleaning efficiency and stability. Simultaneously, the arrangement of the drive motor and drive gear is no longer limited by the traveling gear, offering greater design flexibility and facilitating the optimization of the overall mechanical structure layout of the pool cleaning robot, thus improving space utilization and system integration.

[0014] In the following description of this utility model, the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not mean that the device must have a specific orientation.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0017] like Figures 1 to 3As shown, this utility model provides a drive mechanism for a swimming pool robot. The drive mechanism is symmetrically arranged on both sides of the housing 1, including a motor inside the housing 1 and a travel gear 5 located on the front side of the housing 1; the motor shaft 2 of the motor extends out of the housing 1, and the outer end of the motor shaft 2 is sleeved with a motor gear 3, which meshes with a bridge gear 6.

[0018] The roller brush is located on the front side of the housing 1 and is used to clean the surface of the pool. The roller brush gear 4 is fixed to one end of the roller brush shaft and includes an inner tooth section 4a and an outer tooth section 4b. The bridge gear 6 meshes with the inner tooth section 4a of the roller brush gear 4, and the outer tooth section 4b of the roller brush gear 4 meshes with the inner tooth ring of the travel gear 5. The outer tooth ring of the travel gear 5 meshes with the inner tooth of the track 8.

[0019] The bridge gear 6 and the traveling gear 5 are coaxially arranged; during transmission, the traveling gear 5 and the roller brush gear 4 rotate in the same direction.

[0020] The motor gear 3 drives the bridge gear 6 to rotate, which in turn drives the roller brush gear 4 to rotate, ensuring that the roller brush's rotation speed is unaffected by the robot's travel speed, thereby improving cleaning efficiency and stability. The outer tooth section 4b of the roller brush gear 4 drives the travel gear 5 to rotate, and the outer gear ring of the travel gear 5 drives the track 8 and the driven wheel 7 to rotate.

[0021] Furthermore, the arrangement of the motor and motor gear 3 is no longer limited by the travel gear 5, which provides greater design flexibility and is more conducive to optimizing the overall mechanical structure layout of the pool cleaning robot, improving space utilization and system integration.
