A vehicle body assembly of a vehicle according to an embodiment of the utility model, as shown in fig. 4, includes: a body 40, the body 40 having a body side member 41; the auxiliary frame 100 of the embodiment is further included, and the auxiliary frame 100 is fixedly arranged on the vehicle body longitudinal beam 41 and located below the vehicle body longitudinal beam 41, so that the fatigue strength and rigidity of the auxiliary frame 100 can be improved, and the safety performance of a vehicle is further improved.

According to the vehicle provided by the embodiment of the utility model, the vehicle body assembly of the vehicle comprises the embodiment, so that the fatigue strength and rigidity of the auxiliary frame 100 can be improved, and the safety performance of the vehicle can be further improved.

In the description of the present specification, reference to the terms "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the utility model. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

While embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that: many changes, modifications, substitutions and variations may be made to the embodiments without departing from the spirit and principles of the utility model, the scope of which is defined by the claims and their equivalents.
