The invention provides a front auxiliary frame of a new energy automobile and a vehicle, the front auxiliary frame of the new energy automobile comprises a front cross beam and a rear cross beam which are symmetrically arranged in parallel, and longitudinal beams which are respectively arranged on two sides of the front cross beam and the rear cross beam and are used for connecting the front cross beam and the longitudinal beams, the longitudinal beam comprises a front longitudinal beam part connected with the front cross beam and a rear longitudinal beam part connected with the rear cross beam, the front cross beam, the rear cross beam and the longitudinal beam are all of square tube structures, and the outer diameter of the front longitudinal beam part is larger than that of the rear longitudinal beam part so that the rear end of the front longitudinal beam part can be at least partially arranged at the front end of the rear longitudinal beam part in a sleeving mode. And the rear end of the front longitudinal beam part is welded with the side wall of the rear longitudinal beam part. The vehicle comprises the new energy vehicle front auxiliary frame. According to the front auxiliary frame of the new energy automobile, the problem that in the prior art, a front auxiliary frame which is high in production efficiency, low in production cost, reasonable in structural distribution and capable of absorbing energy in collision does not exist is solved.

    本发明提供一种新能源汽车前副车架及车辆,该新能源汽车前副车架包括对称平行设置的前横梁和后横梁,以及分别设置在所述前横梁和所述后横梁两侧用于连接所述前横梁和所述纵横梁的纵梁,所述纵梁包括与所述前横梁连接的前纵梁部,和与所述后横梁连接的后纵梁部,所述前横梁、后横梁和所述纵梁均为方管结构,所述前纵梁部的外径大于所述后纵梁部,以使所述前纵梁部后端至少部分套设在所述后纵梁部前端上,所述前纵梁部后端与所述后纵梁部侧壁焊接。车辆包括上述新能源汽车前副车架。本发明中的新能源汽车前副车架,解决了现有技术中的缺少一种生产效率高但生产成本低且结构分布合理具备碰撞吸能效果的前副车架的问题。
