[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0023] like Figure 1-5 As shown, the steel-aluminum hybrid body door opening includes a body door opening 1 and a B-pillar 2 arranged on the body door opening 1. The body door opening 1 is provided with an inner stopper 3 and an outer stopper 4 inside and outside, respectively. The inner stopper 3 and the outer stopper 4 are aluminum plates. The ends of the inner stopper 3 and the outer stopper 4 are riveted to the plates of the B-pillar 2 by rivets 5, respectively. Specifically, the body door opening 1 is also provided with a door opening rubber strip, which covers the connection between the inner stopper 3 and the inner stopper 4.

[0024] When in use, the inner stop 3 is installed on the inner side of the door opening 1 on the vehicle, and the two ends of the inner stop 3 are abutted against the plate of the B-pillar 2. The outer stop 4 is installed on the outer side of the door opening 1 on the vehicle, and the two ends of the outer stop 4 are abutted against the plate of the B-pillar 2. The connection between the inner stop 3, the outer stop 4 and the plate of the B-pillar 2 is achieved by two rivets 5. The strength of the vehicle body door opening 1 is higher, the installation of the stop on the vehicle body door opening 1 is convenient and quick, and the structural integrity of the vehicle body door opening 1 is higher.
