A third arc beam is arranged between the lower parts of the left upright post and the right upright post, a fourth arc beam is arranged above the left upright post and the right upright post with a backward opening, the opening of the fourth arc beam is downward, the left end and the right end of the fourth arc beam are respectively connected with the top ends of the left upright post and the right upright post through second diagonal braces, and left and right arc upright posts are arranged between the third arc beam and the fourth arc beam.

Preferably, a fifth arc beam is arranged above the first arc beam, and the fifth arc beam is connected with the first arc beam at the upper side through left and right third support columns.

Preferably, a steering column support is arranged on the fifth curved beam.

Preferably, the first curved beam on the upper side is provided with a left wiper arm bracket and a right wiper arm bracket, and a wiper bracket assembly is arranged between the left wiper arm bracket and the right wiper arm bracket.

Preferably, a third diagonal brace is arranged between the fifth curved cross beam and the first support column.

Compared with the prior art, the invention has the advantages that:

1. According to the invention, the anti-collision structure is arranged between the upper parts of the left upright post and the right upright post, so that when a vehicle collides with the vehicle with a higher vehicle body in the front direction, the effect of protecting the vehicle body can be achieved, and the safety of the vehicle is greatly improved;

2. the invention has simple structure and reasonable design, can meet the installation space requirements of related components (the windscreen wiper and the steering column bracket), has no interference among the components, and is beneficial to subsequent repair and maintenance;

3. The invention can play a role in buffering the curved beam to a certain extent, and the diagonal bracing arranged between the curved beam and the supporting column can improve the strength of the curved beam, thereby playing a role in effectively protecting the safety of a driver in the event of collision.
