AI Technical Summary

Technical Problem

The existing subframes have vibration and noise problems at the connections, and the deformation cannot be monitored in real time during collision or collision, which poses safety risks, and cracks are easily generated at the welding point during collision, which reduces the overall strength.

Method used

A multi-function subframe is designed, with front and rear casing connections, built-in protective devices including inner sheath sleeves, pressure sensors and rubber pad rings, real-time monitoring and shock absorption through locking bolts and pressing rods, and battery compartments and reinforcement beams are provided at the bottom to optimize space utilization and strength.

Benefits of technology

It effectively reduces vibration and noise at the connections at the subframe, monitors the deformation of the connection in real time, reminds car owners to carry out maintenance, improves the overall strength and sound insulation effect of the subframe, and enhances the safety performance during collisions.

Abstract

The invention relates to a multifunctional auxiliary frame, and relates to the technical field of vehicle body structures, the multifunctional auxiliary frame comprises an auxiliary frame, the auxiliary frame is provided with two front sleeves and two rear sleeves which are used for connection and installation, and the auxiliary frame is provided with a protection device; the protection device comprises an inner protection sleeve which is inserted and installed in the front sleeve from the bottom of the auxiliary frame, an annular groove is formed in the inner protection sleeve, two pressure sensors are symmetrically installed in the annular groove of the inner protection sleeve, and two embedded circular grooves for installing the pressure sensors are formed in the annular groove of the inner protection sleeve. An inner abutting ring is arranged in the annular groove of the inner protective sleeve in a sliding mode through two pushing and abutting springs, and an abutting auxiliary piece is arranged in the portion, located above the inner protective sleeve, of the front sleeve. The auxiliary frame has the advantages that vibration and road noise at the connecting position of the auxiliary frame can be reduced, the sound insulation effect is improved, deformation generated by the connecting portion of the auxiliary frame can be monitored in real time, meanwhile, space utilization of the auxiliary frame can be optimized, and the safety performance during collision can be improved.
