"被" structure is a fundamental structure very commonly used in Chinese to represent the passive voice. The basic form of it is "A+被+B+verb", denotes "A be done sth. by B". No specific tense required, but in 80% cases used in past tense (with "了" behind the whole sentence). I'll give you a few examples: 1."苹果被我吃了" - "The apple was eaten by me." That's in past tense. 2."他将被隔离观察14天" - "He will be quarantined for observation for 14 days." - That's one of the 20% cases in future tense. You can discover that the agent(B) can be omitted sometimes such as the latter example, but the patient(A) is indispensable. e.g. "窗户被打破了" - "Windows were broken(by somebody)", the object is omitted. But "被他打破了" is a wrong sentence in grammar because it lacks subject.

被，we aften use this sentence to express the bad things。 比如说： 1.下雨了，他没带伞。 他被雨淋湿了。 他被淋湿了。 2.他的手机被小偷偷了。 他的手机被小偷偷走了。 3.他被车撞了。 他被车撞伤了。 他被撞了。 他被撞伤了。

yes, it's just passive vioce and have nothing to do with tense. You can use it in any tense.

被 is used in passive voice; be made to do you can use it in any tense
