Description

Technical Field

[0001] The utility model relates to the technical field of wall-climbing robots, and in particular to a roller brush structure for a wall-climbing robot. Background Art

[0002] The wall-climbing robot's roller brush is primarily used to scrub walls, removing dirt, dust, and other impurities through its rotational motion. This structure is not only suitable for flat surfaces but also, to a certain extent, for curved surfaces, enhancing the robot's cleaning capabilities and applicability.

[0003] Existing devices have some disadvantages during use. For example, the driving motor of existing robot brushes is generally external, and a belt (or gear) is required to drive the brush, which causes energy loss and takes up space. For example, when the driving motor drives the brush through a transmission device such as a belt or gear, due to the friction between the belts or gears and the mechanical loss during the transmission process, part of the energy will be consumed during the transmission process, thereby reducing the energy utilization efficiency of the entire system. In addition, transmission devices such as belts or gears require a certain amount of space to be installed and arranged, which takes up a large amount of space. Utility Model Content

[0004] The purpose of the utility model is to provide a roller brush structure for a wall-climbing robot, which solves the problem that the driving motor of the robot brush is generally external, and the brush needs to be driven through a belt (or gear), resulting in energy loss and space occupation.

[0005] The utility model provides the following technical solutions: a roller brush structure for a wall-climbing robot, comprising a brush barrel, connecting blocks are provided on both sides of the interior of the brush barrel, the outer walls of the two connecting blocks are fixed to the inner wall of the brush barrel, a motor fixing barrel is inserted at the opening of the brush barrel, a driving motor for driving the brush barrel is fixedly installed in the motor fixing barrel, the output end of the driving motor is fixed to the center of the corresponding connecting block, a sealing assembly for waterproofing is provided on the outside of the driving motor, a mounting plate is fixedly installed on the end of the two motor fixing barrels away from the driving motor, and a connector for connecting external devices is provided on the outer wall of the mounting plate.

[0006] In the above solution, the sealing component is provided so that the wall-climbing robot can work normally in a humid or rainy environment without affecting the normal use of the drive motor.

[0007] As a preferred embodiment of the above technical solution, the sealing assembly includes a connecting sleeve fixedly sleeved on the outer wall of the driving motor, a sealing sleeve is sleeved on the outer wall of the connecting sleeve, an internal thread is opened on the outer wall of the connecting sleeve, an external thread is fixedly connected to the inner wall of the sealing sleeve, and the sealing sleeve is threadedly sleeved on the internal thread of the connecting sleeve through the external thread.

[0008] In the above solution, when the sealing sleeve and the connecting sleeve are tightly matched, a good waterproof sealing effect can be achieved.

[0009] As a preferred embodiment of the above technical solution, a wire hole is provided at the center of the mounting plate.

[0010] In the above solution, the provision of the wire hole enables the power wire to enter the inside of the brush barrel and be connected to the drive motor.

[0011] As a preferred embodiment of the above technical solution, both ends of the brush tube are open structures, and the inner side of the brush tube is a hollow structure.

[0012] The above solution can accommodate the drive motor, connection block and other necessary components.

[0013] As a preferred embodiment of the above technical solution, both ends of the motor fixing cylinder are open structures, and the inner side of the motor fixing cylinder is a hollow structure.

[0014] In the above solution, the internal space of the motor fixing cylinder is used to accommodate the driving motor.

[0015] As a preferred embodiment of the above technical solution, there is a gap between the inner wall of the brush cylinder and the outer walls of the motor fixing cylinder and the sealing sleeve.

[0016] In the above solution, the reserved gap can reduce the friction and wear between the inner wall of the brush cylinder and the outer walls of the motor fixing cylinder and the sealing sleeve.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] In the utility model, the driving motor is built into the two ends of the brush barrel, which reduces the space occupied, and the driving motor directly drives the brush, reducing energy loss and ensuring the coaxiality of the driving motor and the brush core. The sealing component provided can prevent water or other liquids from entering the driving motor during cleaning and causing damage, and this is also the key to ensuring that the robot can work normally in humid or rainy environments.

[0026] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a roller brush structure for a wall-climbing robot, including a brush barrel 1, connecting blocks 2 are provided on both sides of the inside of the brush barrel 1, the outer walls of the two connecting blocks 2 are fixed to the inner wall of the brush barrel 1, a motor fixing barrel 3 is inserted at the opening of the brush barrel 1, a driving motor 4 for driving the brush barrel 1 is fixedly installed in the motor fixing barrel 3, the output end of the driving motor 4 is fixed to the center of the corresponding connecting block 2, a sealing component 5 for waterproofing is provided on the outside of the driving motor 4, a mounting plate 6 is fixedly installed on the end of the two motor fixing barrels 3 away from the driving motor 4, and a connector 7 for connecting external devices is opened on the outer wall of the mounting plate 6. , install the connecting head 7 on the roller brush structure on the device at the connection of the wall-climbing robot, and drive the connecting block 2 to rotate through the provided driving motor 4, which drives the brush barrel 1 to rotate synchronously, so as to achieve the effect of cleaning the wall through the brush barrel 1. The provided sealing component 5 can prevent water or other liquids from entering the driving motor 4 during cleaning and causing damage, and this is also the key to ensuring that the wall-climbing robot can work normally in a humid or rainy environment. In the above device, the driving motor 4 is built into the two ends of the brush barrel 1, which reduces the space occupied, and the driving motor 4 directly drives the brush, reducing energy loss, and ensuring the coaxiality of the driving motor 4 and the brush core.

[0027] As an implementation method in this embodiment, Figure 3As shown, the sealing assembly 5 includes a connecting sleeve 51 fixedly sleeved on the outer wall of the driving motor 4, a sealing sleeve 52 is sleeved on the outer wall of the connecting sleeve 51, an internal thread 511 is opened on the outer wall of the connecting sleeve 51, and an external thread 521 is fixedly connected to the inner wall of the sealing sleeve 52. The sealing sleeve 52 is threadedly sleeved on the internal thread 511 of the connecting sleeve 51 through the external thread 521. During specific use, the sealing sleeve 52 is threadedly sleeved on the internal thread 511 of the connecting sleeve 51 through its external thread 521. When the sealing sleeve 52 and the connecting sleeve 51 are tightly matched, a waterproof barrier is formed between them. This barrier can effectively prevent water or other liquids from entering the interior of the driving motor 4 from the outside, thereby protecting the motor from damage and achieving a good waterproof sealing effect.

[0028] As an implementation method in this embodiment, Figure 4 As shown, a wire hole 61 is provided at the center of the mounting plate 6, and the wire hole 61 allows the power line of the drive motor 4 to pass through, thereby realizing the electrical connection between the drive motor 4 and the power supply or control system of the wall-climbing robot.

[0029] Among them, the two ends of the brush tube 1 are open structures, and the inner side of the brush tube 1 is a hollow structure, which can accommodate the drive motor 4, the connecting block 2 and other necessary components. Among them, the two ends of the motor fixing tube 3 are open structures, and the inner side of the motor fixing tube 3 is a hollow structure, which is used to accommodate the drive motor 4 and facilitate the passage of the power cord.

[0030] Among them, there is a gap between the inner wall of the brush tube 1 and the outer wall of the motor fixing tube 3 and the sealing sleeve 52, which can reduce the friction and wear between the inner wall of the brush tube 1 and the outer wall of the motor fixing tube 3 and the sealing sleeve 52, which helps to extend the service life of the brush tube 1 and keep the brush tube 1 in good working condition.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
