Description

CROSS REFERENCE TO RELATED APPLICATION This application is an U.S. national phase application under 35 U.S.C. § 371 based upon international patent application No. PCT/EP2022/064436 filed on May 27, 2022, which itself claims priority of Chinese Patent Application No. 2021105807002, entitled “AUTOMATIC WEBBING WINDING DEVICE AND BEDSIDE BED HAVING THE SAME”, filed on May 26, 2021, the entire content of which is incorporated herein by reference. TECHNICAL FIELD The present disclosure relates to the technical field of beds, and more particularly, to an automatic webbing winding device and a bedside bed having the same. BACKGROUND Bedside beds (for example, cribs) are convenient for caregivers to take care of infants, which can especially resolve the problem that caregivers need to get up frequently at night to take care of infants. When the caregivers sleep at night, the bedside bed can be placed next to the adult bed for easy care. In order to fix the bedside bed relative to the adult bed, and to avoid an excessive gap between the two, a webbing is usually used to fix the bedside bed to the adult bed. However, if the caregiver does not pack the webbing properly after use, the webbing looks messy and untidy. In addition, when the webbing is not used (when the bedside bed does not need to be fixed), the webbing cannot be wound up automatically. Consequently, it is very inconvenient for the user to wind up the webbing, and the webbing is also likely to be thrown away and lost after being removed. Therefore, it is necessary to provide an automatic webbing winding device and a bedside bed having the same to resolve the foregoing shortcomings in the prior art. SUMMARY According to some embodiments, an automatic webbing winding device and a bedside bed having the same are provided. An automatic webbing winding device includes: a base; a winding reel mounted on the base and rotatable around a center of the base; a coil spring mounted on the winding reel, wherein one end of the coil spring is fixed to the winding reel, and the other end of the coil spring is fixed to the base; and a webbing mounted on the winding reel, wherein the webbing includes a fixed end and a free end, the fixed end is fixed to the winding reel, and the free end extends out from the base; wherein when the free end is pulled outward by an external force, the winding reel rotates along a forward direction, and the coil spring is elastically deformed, when the external force is removed, the winding reel rotates along a reverse direction under an elastic restoring force of the coil spring, thereby winding the webbing on the winding reel. A bedside bed includes a bottom plate; a plurality of side plates surrounding the bottom plate; and the aforementioned automatic webbing winding device.
