No. 11,350,705, issued on Jun. 7, 2022, which claims the benefit of Chinese Patent Application No. 202010621957.3, filed Jun. 30, 2020, and Chinese Patent Application No. 201910648903.3, filed Jul. 17, 2019, the contents of each of which are incorporated herein by reference.

The present invention relates to a child product, and more specifically, to a buckle assembly.

With development of economy and advancement of technology, there are more and more consumer products available in the market to bring convenience in people's life. Child carriers are one of the consumer products.

It is well-known that straps are indispensable for the child carriers, and buckle assemblies are commonly used on the straps for fastening and unfastening the straps.

Currently, a conventional buckle assembly includes a male buckle, a female buckle for engaging with the male buckle and a release button. The male buckle the female buckle can be disengaged from each other by the release button. The release button is usually located at a front surface or a rear surface of one of the male buckle and the female buckle for providing an easy access for a user to operate the release button. However, since the release button is located at such a conspicuous place, it is easy for a child sitting in a child carrier to recognize existence of the release button, which leads to a potential hazard caused by an unintentional release operation of the buckle assembly due to the child's subconscious touching. Meanwhile, when the release button of the conventional buckle assembly is operated, it is required to apply a great force on the release button, which causes a difficulty in the release operation. Furthermore, the configuration of the release button located at the front surface or the rear surface of the one of the male buckle and the female buckle increases a possibility of being hit by other objects, which also leads to the potential hazard caused by the unintentional release operation of the buckle assembly. Although there is a buckle assembly having an inconspicuous release button, such buckle assembly has a complicated structure and a difficult release operation.

Therefore, there is a need to provide an improved buckle assembly to solve the aforementioned problems.
