Description

TECHNICAL FIELD The present disclosure belongs to the technical field of rocking chairs, more particularly to a multidimensional rocking chair. BACKGROUND Babies often need gentle shaking during their growth process to gain a sense of safety and comfort, which is beneficial for soothing or falling asleep. To alleviate the burden on caregivers, various electric rocking chairs or soothing chairs have emerged in the market. Most existing products employ motors or mechanical transmission devices to drive a seat to swing, simulating the effect of manual shaking. In existing technologies, common baby rocking chairs can be generally divided into two types. One is to swing the seat back and forth through a bracket structure. The other is to drive the seat to swing left and right through base transmission. Although this shaking method of single degree of freedom can achieve a certain degree of soothing effect, it is still difficult to simulate the common compound movements in parents embrace, such as the combination of up and down gentle shaking and horizontal swing, resulting in limited experience for babies. In addition, in terms of backrest adjustment, existing baby rocking chairs often employ simple rotating shaft and slot structures to achieve angle adjustment. This type of structure generally has problems such as inconvenient adjustment, few angle positions, and unreliable positioning. When a baby is moving on the seat, the angle of the backrest is easy to change, which poses a safety hazard. Further, in terms of installation and cleaning, most existing baby rocking chairs adopt a fixed installation, and the connection between the seat and a base does not feature a quick-release function. This not only makes cleaning and maintenance inconvenient, but also presents a bulky device when in transport or storage. Still further, most existing rocking chairs have a fixed orientation and lack easy seat rotation function. Parents often need to frequently move the entire device when feeding or taking care of a baby, which complicates operation and negatively impacts the user experience. Therefore, the existing baby rocking chairs have shortcomings in terms of movement dimension, backrest adjustment, safety locking, seat quick-release, rotation flexibility and so on, and there is an urgent need to improve them. SUMMARY It is an object of the present disclosure to provide a multidimensional rocking chair against the shortcomings of the existing technologies, which is to overcome the problems of the existing technologies such as single mode of movement, inconvenient backrest adjustment, difficulty in disassembling and assembling a seat, and inflexible rotation. In order to achieve the above object, the present disclosure employs the following technical solution. A multidimensional rocking chair includes: a reclining seat including a seat cushion part and a backrest part; anda base having provided therein a driving machine, the driving machine having an output end connected to the reclining seat to drive movement of the reclining seat. Herein, the driving machine includes a horizontal sliding module and a vertical lifting module. The horizontal sliding module is configured to drive the reclining seat to move horizontally, and the vertical lifting module is configured to drive the reclining seat to move vertically. Further, the seat cushion part and the backrest part have a hinged connection therebetween, and an included angle between the backrest part and the seat cushion part is adjustable. Further, a plurality of locating holes are arranged at the hinged connection between the seat cushion part and the backrest part. The backrest part is formed with a sliding slot; the sliding slot has an insert pin slidably mounted therein; and when the insert pin falls into any one locating hole, the included angle between the backrest part and the seat cushion part is limited at a corresponding position; and Herein, the sliding slot has provided therein a first elastic element; and the first elastic element is configured to apply onto the insert pin an elastic force toward the direction of the locating hole. Further, the hinged connection between the backrest part and the seat cushion part is located at two sides of the backrest part; and a pull rope is provided and connected between the insert pins at the two sides. When the pull rope is pulled, the pull rope causes the insert pin to squeeze against the spring and disengage from the locating hole. Further, a gap is provided between the backrest part and the seat cushion part; and the pull rope can pass through the gap. Further, the multidimensional rocking chair includes a bracket. The bracket is configured to connect the seat cushion part and the output end of the driving machine. The seat cushion part has an outer side provided with a limit part. The seat cushion part is snap-fitted with the bracket by means of the limit part; and the seat cushion part is inclined toward the backres
