Detailed ways

Fig. 1～Fig. 7 have shown a specific embodiment of this household stair automatic cleaning robot of the present invention, and the same as conventional household cleaning robot, it also comprises the dust-absorbing sweeper 1 of belt walking mechanism 6, and this dust-absorbing sweeping The function and structure of the device 1 are similar to those of a household vacuum cleaner or a sweeping robot.

The key improvement of this embodiment is that the robot also includes a mounting frame 2 , a horizontal movement drive mechanism 3 , a telescopic support 4 and a telescopic drive device 5 . in:

The installation frame 2 is connected to the dust suction cleaner 1 , and the installation frame 2 can move in the front and back horizontal direction relative to the dust suction cleaner 1 .

The horizontal movement driving mechanism 3 is used to drive the dust suction cleaner 1 and the installation frame 2 to move relative to each other in the front and rear horizontal directions.

The telescopic bracket 4 is connected to the installation frame 2, and the telescopic bracket 4 can be extended/folded in the vertical direction.

The telescopic drive device 5 is used to drive the telescopic support 4 to expand/close in the vertical direction.

With reference to Fig. 4～shown in Fig. 7, when using this household stair automatic cleaning robot to clean the stairs, earlier this robot is placed on the stair entry ground at the lower end of the stairs. The telescopic drive device 5 controls the telescopic support 4 to expand vertically, and then the dust suction cleaner 1 is lifted to the height of the first step of the stairs. At this time, the bottom of the telescopic support 4 is supported on the ground, and the upper part supports the dust suction cleaner 1. Figure 4. Then, the horizontal movement driving mechanism 3 controls the dust suction cleaner 1 to move forward relative to the installation frame 2, so that the dust suction cleaner 1 is located above the first step of the stairs, as shown in FIG. 5 . Afterwards, the telescopic drive device 5 controls the telescopic bracket 4 to close vertically, so that the dust suction cleaner 1 falls on the first step of the stairs, and the telescopic bracket 4 in the closed state is supported and connected to the dust suction cleaner 1. Figure 6. Then, the horizontal movement drive mechanism 3 controls the installation frame 2 to move forward relative to the dust suction cleaner 1, so that the installation frame 2 and the dust suction cleaner 1 are restored to the original state, and the dust suction cleaner 1 carries out the step on the first step of the stairs. Cleaning and vacuuming, after the first stage of the stairs is cleaned and vacuumed, repeat the above action to clean and vacuum the second stage of the stairs, and so on, to complete the cleaning and vacuuming of the entire staircase.

This robot is when climbing stair steps, owing to will vacuum cleaner 1 be pushed to correct stair height, so this robot is provided with the sensor of inductive stair height. In order to prevent the robot from tilting due to the shift of the center of gravity caused by the forward movement of the vacuum cleaner 1 when the screw rod pushes the vacuum cleaner 1 onto the steps, the robot is placed between the vacuum cleaner 1 and the mounting frame 2 A distance sensor is installed to detect the distance between the two. When the distance between the front of the vacuum cleaner 1 and the stair wall is less than 1 cm, the trolley stops moving forward and starts the screw motor to drive the screw to rotate, and the vacuum cleaner 1 Push placed on the steps.

In this example, the dust suction cleaner 1 includes a housing 1a, a dust cup (the dust cup is provided with a filter screen) installed in the housing, and is set at the bottom of the housing and communicated with the dust cup. The dust suction port 1b, the negative pressure blower arranged in the housing and in air communication with the dust suction port. Moreover, a dust cup cover 1c for opening/closing the dust cup is provided on the top of the housing 1a. During work, the negative pressure suction produced by the negative pressure exhaust fan sucks the dust in the environment into the dust cup, and after the dust suction is completed, the dust cup cover 1c is opened to pour out the dust.

In addition, in this example, three roller brushes 1d arranged on the periphery of the dust suction port 1b are installed on the bottom of the housing 1a, and these three roller brushes are respectively arranged on the front, left and right sides of the dust suction port 1b. This ensures that the dust around the dust suction port 1b can be swept into the dust suction port, and then sucked into the dust cup.

And in this example, the dust suction port 1b is designed as a "ten" shape. In this way, the garbage swept in by the front roller brush and the garbage swept in by the side roller brush can be easily sucked into the suction port. Figure 3.

In this example, the traveling mechanism 6 includes a traveling motor (not shown in the figure), two driving wheels 6a and two driven wheels 6b. The two driving wheels 6a are connected to the traveling motor, and the two driving wheels 6a and the two driven wheels 6b are arranged at the bottom of the vacuum cleaner 1 and distributed in a rectangular shape. During work, the electric driving wheel 6a of the walking motor rotates, and drags the dust-absorbing cleaner 1 to walk, and during the walking of the dust-absorbing cleaner 1, the driven wheel 6b is subjected to the frictional force to follow the rotation.

In order to enable the vacuum cleaner 1 to have a turning function, obstacles can be avoided during walking. The driven wheel 6b in this example adopts a universal roller, and the traveling mechanism 6 also includes two turntables 6c that are horizontally rotatably connected to the bottom of the dust-absorbing cleaner 1, and the two driving wheels 6a are respectively Installed on these two turntables 6c, the running gear 6 with this steering function is often used on toy cars. Of course, we can also set a steering drive device connected with the turntable 6c to actively control the steering of the vacuum sweeper 1 .

Described horizontal movement driving mechanism 3 comprises the screw mandrel 6a that is connected between described dust suction sweeper 1 and mounting frame 2, drives the screw mandrel motor (not shown in the figure) that described screw mandrel rotates. When working, the screw motor drives the screw 6a to rotate, and then drives the dust cleaner 1 and the mounting frame 2 to move relative to each other along the axial direction of the screw, so that the dust suction cleaner 1 and the mounting frame 2 are close to each other in the front and rear horizontal directions / move away from each other.

The telescopic bracket 4 includes two half-frames respectively arranged on the left and right sides of the installation frame 2, and each of the half-frames includes a support base plate 4a, two first poles 4b and two second poles. The connecting rod 4c, the two first struts 4b are arranged in an "X" shape crossing and are hinged to each other, the two second connecting rods 4c are arranged in an "X" shape and are crossing and are hinged to each other, the two first One end of the support rod 4b is hinged on the support base plate, one end of the two second connecting rods 4c is hinged on the mounting frame, and the other end of the two first rods 4b is connected to the two second connecting rods 4b. The other ends of the two connecting rods 4c are respectively hinged.

The telescopic driving device 5 is an electric push rod with one end hinged on the support base 4a and the other end hinged to one of the second connecting rods 4c.

When the electric push rod was extended, the telescopic support 4 was extended and expanded upwards. When the electric push rod shrinks, the telescopic support 4 makes a downward shrinking and folding action.

Certainly, the above-mentioned embodiments are only for illustrating the technical conception and characteristics of the present invention, and the purpose is to enable people to understand the content of the present invention and implement it accordingly, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the main technical solutions of the present invention shall fall within the protection scope of the present invention.
