The vehicle body bracket 73 is installed on the frame beam 72 and is used for clamping with the connection bracket 1 of the luggage rack installation structure; the vehicle body bracket 73 is in a shape of a capital letter "J", and specifically includes a main body plate, two support arms extending from the two side edges of the main body plate along the same side of the main body plate, and a lapping plate extending from one side of the two support arms in opposite directions, the lapping plate is installed on the frame beam 72, a clamping space is formed between the main body plate and the frame beam 72, and a bayonet 2 is arranged on the main body plate; during installation, the clamping plate 13 is clamped in the clamping space, and the buckle 15 is clamped in the bayonet 2, so that the connection bracket 1 and the vehicle body bracket 73 can be firmly clamped together, and then the luggage rack beam 3 is installed on the connection bracket 1. With such a setting, the weight of the luggage is transmitted to the connection bracket 1 through the bearing surface of the luggage rack beam 3 and the connection bracket 1, and the connection bracket 1 is further transmitted to the reinforcement plate 712 of the upper side beam of the vehicle body main body 7 through the anti-scratching structure 16 adhered to the connection bracket 1; there is enough clearance between the bearing surface of the connection bracket 1 and the outer side panel 711 of the vehicle body to prevent the outer side panel 711 of the vehicle body from bearing the weight of the luggage; at the same time, the anti-scratching structure 16 can prevent the contact surface of the outer side panel 711 of the vehicle body from being scratched and rusted. In this example, a special connection bracket 1 is used to ensure that the weight of the luggage is transmitted to the high-strength side beam of the vehicle body main body 7, the outer side panel 711 of the vehicle body hardly bears the weight of the luggage, and the roof cover does not bear the weight of the luggage at all; the appearance state of the outer side panel 711 of the vehicle body is ensured, the acceptance of the later installed luggage rack by people is improved, and the vehicle sales volume is promoted; the problem of deformation of the outer side panel 711 of the vehicle body caused by the outer side panel 711 of the vehicle body mainly bearing the weight of the luggage in the current market and the problem that the roof cover (especially the panoramic glass) is easily damaged are solved. Among them, the panoramic glass is adhered to the lip and fixed on the reinforcement plate 712 of the upper side beam of the vehicle body through glass glue.
