The invention discloses an automobile cross beam and longitudinal beam connecting structure assembly. The assembly comprises a cross beam and a longitudinal beam connected with the cross beam, the cross beam is at least provided with a first mounting part and a second mounting part positioned above the first mounting part, and the longitudinal beam at least comprises a first longitudinal plate anda second longitudinal plate located above the first longitudinal plate. The first installation part is in lap joint with the first longitudinal plate, and the second installation part is in lap jointwith the second longitudinal plate; and the first installation part is further fixedly connected with the first longitudinal plate, and/or the second installation part is further fixedly connected with the second longitudinal plate. The longitudinal beam is of a multi-layer structure, and the longitudinal beam and the cross beam are connected in a multi-layer lap joint and extra fixed connectionmode, so that the rigidity and strength of the lap joint structure are improved, and good bending and modal performance in the driving process is guaranteed.
