Abstract

This utility model discloses a power output structure for a swimming pool robot, including: a drive gear, a traveling wheel, and a roller brush gear. The drive gear is driven and connected to a motor, and is also connected to a stepped gear. The first tooth segment of the stepped gear meshes with the internal gear ring of the traveling wheel, and the second tooth segment of the stepped gear meshes with the roller brush gear via a bridge gear. The roller brush gear is mounted on the rotating shaft of the cleaning roller. The drive gear is mounted on the output shaft of the motor. A bridge drive gear and a second bridge gear are provided between the drive gear and the stepped gear, and a third bridge gear is provided between the second tooth segment of the stepped gear and the roller brush gear.

Description

Technical Field

[0001] This utility model relates to a power output structure for a swimming pool robot, belonging to the technical field of swimming pool cleaning robot. Background Technology

[0002] With the development of automation, robots are increasingly appearing in our lives. Pool cleaning robots are a type of cleaning robot developed to meet the needs of pool cleaning. They can repeatedly clean the pool bottom and walls, as well as filter the pool water. During operation, pool cleaning robots clean contaminants from the pool surface by rotating brush rollers.

[0003] Existing pool cleaning robots use either a separate drive or a traveling roller to drive the cleaning roller. The cost of a separate drive is high, while the rotation speed of the cleaning roller driven by the traveling roller is affected by the travel speed, resulting in lower cleaning power. Therefore, a power output structure for a pool cleaning robot is proposed.

[0004] The existing power transmission mechanism of the pool cleaning machine is driven by the traveling wheel to the bridge wheel and then to the roller wheel. The traveling gear is too small, resulting in stress concentration and short gear life. Utility Model Content

[0005] The purpose of this invention is to overcome the problems existing in the prior art and provide a power output structure for a pool robot that ensures that the rotation speed of the cleaning roller is always several times that of the walking wheel. Therefore, the cleaning effect of the cleaning roller is not easily affected by the rotation speed of the walking wheel, and the main body of the pool robot can have a better cleaning effect even when moving at a slower speed.

[0006] To solve the above technical problems, this utility model provides a power output structure for a swimming pool robot, comprising: a drive gear, a travel wheel, and a roller brush gear. The drive gear is driven and connected to a motor, and is also connected to a stepped gear. The first tooth segment of the stepped gear meshes with the internal gear ring of the travel wheel, and the second tooth segment of the stepped gear is connected to the roller brush gear via a bridge gear. The roller brush gear is mounted on the shaft end of the cleaning roller.

[0007] Furthermore, the drive gear is mounted on the output shaft end of the motor, and the drive gear meshes with the first bridge gear, the first bridge gear meshes with the second bridge gear, and the second bridge gear meshes with the second tooth segment of the stepped gear; the second tooth segment of the stepped gear also meshes with the roller brush gear through the third bridge gear.

[0008] Furthermore, the second bridge gear is coaxial with the traveling wheel.

[0009] Furthermore, the center of the drive gear's shaft is lower than the center of the travel wheel's shaft and located outside the travel wheel.

[0010] Furthermore, the outer toothed ring of the traveling wheel meshes with the track and is connected to the rear traveling wheel via the track.

[0011] Furthermore, the cleaning roller rotates in the same direction as the traveling wheel, and the cleaning roller is located at the bottom front side of the traveling wheel.

[0012] Furthermore, the center of rotation of the stepped gear is higher than the center of rotation of the driving wheel and is located in front of the center of rotation of the driving wheel.

[0013] Furthermore, the rotational speed of the roller brush gear is an integer multiple of the rotational speed of the traveling wheel.

[0014] Compared with the prior art, the present invention has achieved the following beneficial effects: The present invention directly drives the cleaning roller to rotate through the drive mechanism that drives the driving wheel to rotate, ensuring that the rotation speed of the cleaning roller is always several times that of the driving wheel. Therefore, the cleaning effect of the cleaning roller is not easily affected by the rotation speed of the driving wheel, ensuring that the main body of the pool robot can have a better cleaning effect even when moving at a slower speed.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0021] like Figures 1 to 6 As shown, this utility model aims to provide a power output structure for a swimming pool robot 1, including a drive gear 62, a travel wheel 2, and a brush gear 67. The drive gear 62 is connected to a stepped gear 65. The drive gear 62 is mounted on the output shaft of a motor 61. A first bridge gear 63 and a second bridge gear 64 are provided between the drive gear 62 and the stepped gear 65. The drive gear 62 meshes with the first bridge gear 63, the first bridge gear 63 meshes with the second bridge gear 64, the second bridge gear 64 meshes with the second tooth segment of the stepped gear 65, the first tooth segment of the stepped gear 65 meshes with the internal gear ring 21 of the travel wheel 2, the second tooth segment of the stepped gear 65 also meshes with a third bridge gear 66, the third bridge gear 66 meshes with the brush gear 67, and the brush gear 67 is mounted on the rotating shaft of the cleaning roller 5.

[0022] The second bridge gear 64 is coaxial with the traveling wheel 2. The center of rotation of the drive gear 62 is lower than the traveling wheel 2 and located outside the traveling wheel 2. The center of rotation of the stepped gear 65 is higher than the center of rotation of the traveling wheel 2 and located in front of the center of rotation of the traveling wheel 2.

[0023] The outer gear ring of the driving wheel 2 meshes with the track 4 and drives the rear driving wheel 3 to rotate through the track 4, giving the pool robot good obstacle crossing ability and ground adhesion performance, making it suitable for pool environments with various complex terrains.

[0024] The cleaning roller 5 rotates in the same direction as the traveling wheel 2, and is located at the bottom front of the traveling wheel 2. The rotational speed of the roller brush gear 67 is an integer multiple of that of the traveling wheel 2, and the cleaning frequency of the roller brush can be adjusted according to actual cleaning needs to avoid cleaning blind spots or energy waste caused by speed mismatch.

[0025] This invention achieves multi-path power distribution for the motor by setting multiple stepped gears and bridge gears, resulting in a more rational overall structural layout, high space utilization, and improved transmission efficiency. The drive mechanism that drives the walking wheels directly drives the cleaning roller, ensuring that the cleaning roller's rotational speed is always several times that of the walking wheels. Therefore, the cleaning effect of the cleaning roller is not easily affected by the walking wheel speed, guaranteeing optimal cleaning performance even when the pool robot is moving at slower speeds.
