The invention relates to a vehicle front lower protection device and a vehicle, and the vehicle front lower protection device comprises a cross beam main body which is provided with a monitoring device; the frame fixing support is connected to the cross beam main body through an energy absorption mechanism; the switching mechanism is installed on the energy absorption mechanism, the switching mechanism is in signal connection with the monitoring device, and the switching mechanism is configured to switch the energy absorption mechanism to be in rigid connection with the frame fixing support and the cross beam body when the monitoring device monitors the first protection state; and when the monitoring device monitors the second protection state, the energy absorption mechanism is switched to be elastically connected with the frame fixing support and the cross beam body. The frame fixing support and the cross beam body are connected through the energy absorption mechanism, when the monitoring device installed on the cross beam body monitors the first protection state or the second protection state, the state of the energy absorption mechanism can be switched through the switching mechanism, and the buffering performance of lower protection is improved; the technical problem that lower protection with high strength and rigidity may cause great harm to pedestrians is solved.
本申请涉及一种车辆前下防护及车辆,其包括:横梁主体,横梁主体安装有监测装置;车架固定支座,车架固定支座通过吸能机构连接于横梁主体;切换机构,切换机构安装于吸能机构,切换机构与监测装置信号连接,切换机构配置为当监测装置监测出第一防护状态时,将吸能机构切换为刚性连接车架固定支座与横梁主体;当监测装置监测出第二防护状态时,将吸能机构切换为弹性连接车架固定支座与横梁主体。通过将车架固定支座与横梁主体利用吸能机构连接,当安装于横梁主体的监测装置监测出第一防护状态或第二防护状态时,可以利用切换机构切换吸能机构的状态,增加了下防护的缓冲性能,解决了强度及刚度较高的下防护可能对行人造成较大的伤害的技术问题。
