请教，jQuery自定义扩展方法私有函数问题

[winzond]

$.fn.testExtsMthdsPrvtVar = function (options) {
    this.read = function () {
        return this.settings;
    }
    if (typeof options == "object") {
        this.settings = $.extend({ name: "张三" }, options || {});
    } else if (options == "read") {
        this.read();
    }
}

let zs = $();
zs.testExtsMthdsPrvtVar({});
console.log(zs.testExtsMthdsPrvtVar("read"));

输出的是undefined，请问怎样才能达到输出{ name: "张三" }的目的呢？
