The invention provides a vacuum booster structure, a vacuum booster assembly and a moving body with the vacuum booster assembly. The vacuum booster structure comprises a front shell, a rear shell anda diaphragm, and the diaphragm, the front shell and the rear shell form a vacuum cavity and an air cavity; and the front shell is provided with a first through hole, a peripheral edge of the first through hole is sunken into the vacuum cavity, and the other parts of the front shell protrude outwards relative to the vacuum cavity. The number of parts can be reduced, weight and cost of a whole vehicle are reduced, meanwhile, a vacuum leakage failure risk is decreased, and vehicle safety is improved.
本发明提供一种真空助力器结构、真空助力器总成及具有其的移动体,真空助力器结构包括前壳体、后壳体和膜片,所述膜片分别与所述前壳体和所述后壳体形成真空腔和空气腔;所述前壳体具有第一贯穿孔,所述第一贯穿孔的周沿部,向所述真空腔内凹陷,并且所述前壳体的其他部分相对所述真空腔外凸。本发明能减小零部件数量,降低整车重量和成本,同时降低真空泄漏失效风险,提高车辆安全性。
