Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0036] In the prior art, the number of gratings (or teeth) is usually calculated to control the swing speed of the swing, because the grating disc is not on the motor shaft, but on the output shaft, and the rotation speed of the shaft output shaft is very small, so the number of teeth passing through There are only 1~2 teeth, the control accuracy is very poor, and it cannot meet the requirements of accurately controlling the swing speed of the swing.

[0037] The structure of children's swing dining chair see figure 1 As shown, the top of the support frame 1 is connected to a pair of hangers 3, and the pair of hangers 3 are respectively connected to the seat 4. The top of the support frame 1 is...

Abstract

The invention discloses a shaking control method, which comprises double photoelectric sensors and a grating, and comprises the following steps of: detecting the time when a grating interrupting or opening part passes through the photoelectric sensors; in each shaking period, comparing the shortest time value with a time value corresponding to a preset shaking amplitude, and when the shortest time value is not equal to the preset time value, generating a control signal for adjusting the output power of the motor so as to enable the shaking amplitude to reach the preset shaking amplitude; detecting a current shaking direction; and judging whether the current shaking direction is changed or not, and when the current shaking direction is changed, generating a control signal for adjusting the output power of the motor to perform homodromous supplementary stress application. The swing speed of a swing is controlled by calculating the time value of the blocking or opening part of the grating passing through the photoelectric sensors, the control precision is improved, and the problem of insufficient precision is effectively solved. Forward and reverse same-direction supplementary force application is correspondingly carried out according to the shaking direction, and shaking power can be corrected in advance.

Description

technical field [0001] The invention belongs to the technical field of rocking control of swing rocking chairs, and in particular relates to a rocking control method of a swing dining chair, a rocking chair or a rocking bed, and also relates to a rocking control device. Background technique [0002] In recent years, children's swing dining chairs, rocking chairs and cradles have developed rapidly. [0003] However, the US and European high-performance swing control technology patents have been controlled by the US company KIDSII. Its core patent US007905791B2 has been controlling the US baby swing market due to its high control accuracy and low production cost. Now, on the basis of the structure shown in Graco's expired patent US6339304B1, the control algorithm has been improved to eliminate the defect of low precision of the original algorithm, and achieve the same shaking performance as the KIDS II company's patent, thus entering the US market.
