Embodiment 1

[0047] Embodiment 1 A steering structure of an intelligent steering device, see Figure 1-3 : including a control module, a sensing module 3, a steering module and a drive module 10, the steering module is provided with two sets of reflective sensing units, and the sensing module 3 electrically connected to the control module is correspondingly directed to the reflective sensing unit; the steering module is driven by The module 10 is driven, and the reflective sensing unit rotates with the steering module and has an angular deviation with the sensing module 3; the sensing module 3 forms a sensing signal with the angular deviation signal and sends it to the control module, and the control module converts the sensing signal into The control signal is sent to the driving module 10 .

[0048] Such as Figure 9 As shown, the reflective sensing unit is two non-same-color reflective elements, and the two non-same-color reflective elements occupy the same area of ​​the reflective sen...

Embodiment 2

[0054] Embodiment 2 A steering structure of an intelligent steering device, see Figure 1-4 6. In this embodiment, the connection relationship and basic action principle of the sensing module, the control module, the driving motor and the steering module are the same as those in the foregoing embodiment, and will not be repeated here.

[0055] The difference is that a supporting mechanism 9 corresponding to the sensing module 3 protrudes from the torsion arm 8, and the two reflective elements are correspondingly and adjacently distributed on the upper end surface of the supporting mechanism 9; the supporting mechanism 9 is vertically The main shaft 7d of the universal drive wheel 7; the drive module 10 is a drive motor electrically connected to the control module.

[0056] The reflective light sensor points to two sets of reflective sensing units, and the reflective light sensor continuously sends out strong light signals at a set frequency, and the two non-color reflective el...

Embodiment 3

[0058] Embodiment 3 A steering structure of an intelligent steering device, see Figure 1-8 : In this embodiment, the connection relationship of the sensing module, the control module, the driving motor and the steering module are the same as the basic action principles of the previous embodiment, and will not be repeated here.

[0059] The difference is that the drive motor is connected to the torsion arm 8 through the reducer, and the steering module is correspondingly assembled on the sweeper 5; the sweeper 5 is provided with a storage cavity 4 corresponding to the steering module, and the top of the storage cavity 4 A sensing module 3 is provided with a relatively reflective sensing unit.

[0060] There are two obstacle sensors 6 electrically connected to the control module in front of the sweeper 5, and the obstacle sensors 6 are reflective light sensors, at least including a light emitting end 3a and a receiving end 3b.

[0061] Specifically, when the sweeping machine 5...

Abstract

The invention relates to a steering structure of an intelligent steering gear, comprising a control module, a sensing module, a steering module and a driving module, wherein two sets of light reflecting sensing units are arranged on the steering module, and the sensing module electrically connected with the control module correspondingly points to the light reflecting sensing units; the steering module is driven by the driving module, and the light reflecting sensing units generate angular deviation with the sensing module along with rotation of the steering module; two adjacent homochromaticlight reflecting elements are arranged on the light reflecting sensing units, two light receiving ends symmetrically arranged in the sensing module detect the light reflecting intensity simultaneously, and the control module can accurately detect the rotating angle of the steering module by light reflecting intensity difference and arrangement detected by the sensing module, so as to control steering of the system with high precision.

Description

technical field [0001] The invention relates to the technical field of steering control, in particular to a steering structure of an intelligent steering device using a sensor to control the running state of a universal wheel. Background technique [0002] With the improvement of living standards, sweeping robots have entered people's lives more and more because of their simple operation and convenient use. They are connected with families and offices and become an important member of small household appliances. They are very popular. However, the sweeping robots currently on the market are generally expensive, and it is difficult to popularize the public. The reason is that the general sweeping robots are more complicated in design and use too many electronic components, making the cost expensive; in addition, most sweeping robots use more than two Each drive wheel controls the steering, which is relatively complicated in structure, which makes the overall structural stabil...
