The invention relates to a passenger car door which comprises a car door body, a car door rear inner frame arranged on one side of the car door body, a car door front inner frame arranged on the other side of the car door body, and an anti-collision rod assembly arranged between the car door rear inner frame and the car door front inner frame. The anti-collision rod assembly comprises a first anti-collision rod located between the car door rear inner frame and the car door front inner frame, and a second anti-collision rod parallel to the first anti-collision rod. The passenger car door forms a rectangular sealed frame structure which is quite firm, the overall rigidity of the car door is greatly improved, the anti-collision performance of the car door is improved, the requirements for high strength and lateral collision resistance capacity are met, the car door is not prone to deformation, the overall strength and rigidity of a left front car door and a right front car door can be improved, the energy absorption effect and force transferring effect are good, the deformation resistance is quite high, and the problem that the car door cannot be opened due to the fact that deformation is too severe is solved.
