Description

Buffer assembly and vehicle Technical Field The utility model relates to the technical field of buffer assemblies, in particular to a buffer assembly and a power system. Background With the rapid development of new energy automobiles and intelligent automobiles, vehicles have raised higher requirements on the functionality, safety and intellectualization of electrical systems. The power distribution system is used as a core component of the vehicle electrical architecture, bears the tasks of high-efficiency distribution of the electric energy of the whole vehicle and power supply management of various electrical equipment, and plays a vital role in guaranteeing the stable operation and driving safety of each functional unit of the vehicle. In the prior art, vehicle power distribution systems have generally employed rigid mounting arrangements in which components such as a power distribution box are directly secured to a vehicle body structure by means of metal brackets or fasteners. The traditional installation mode has simple structure and lower cost, but has obvious technical defects in the practical application process. First, vehicles often face complex road conditions during travel, and vibrations from the road surface and occasional mechanical shocks are inevitably transmitted to the various components of the vehicle body. Under the action of long-term vibration and impact, the problems of loosening of the installation part, loosening of a fastener, relative displacement between the power distribution system and a vehicle and the like easily occur in the traditional rigidly-installed power distribution system, and poor contact of connectors, electrical connection faults and even normal operation of the system are further caused. In addition, the accumulation of mechanical stresses may also cause damage to the power distribution system housing or internal circuit board, reducing the overall reliability and service life of the system. Secondly, the installation process of the existing power distribution system is generally complex in operation, accurate alignment and repeated fastening are needed, the assembly process difficulty and the manual operation strength are increased, and the later maintenance and replacement are not facilitated. The intelligent and high-voltage power distribution capacity of part of vehicles is improved, higher requirements are put forward on the volume, the weight and the protection level of a power distribution system body, the requirements of the high-performance electric system on vibration resistance and impact resistance are difficult to meet in the traditional rigid mounting mode, and the requirements are easy to be weak links of the safety management of the whole vehicle. In view of the above problems, some of the technical solutions have attempted to add cushioning materials such as flexible gaskets, rubber washers, etc. between the power distribution system and the vehicle body to absorb and dampen some of the vibrations and shocks. However, these simple buffering measures have a single structure and limited buffering performance, and have the defects of weak installation, easy aging and failure, and the like, and are difficult to continuously play a role under the high-strength working condition. Therefore, how to ensure the efficient and safe power supply of the power distribution system, and simultaneously improve the vibration resistance and impact resistance of the installation of the power distribution system, simplify the assembly process, improve the overall reliability and the service life, and become a technical problem to be solved in the field of vehicle electrical systems.
