The invention relates to the technical field of sealing structures, in particular to a vehicle body equipment via hole sealing structure which comprises a vehicle body covering part and vehicle-mounted equipment, a via hole is formed in the vehicle body covering part, a sealing assembly is arranged at the via hole, and the sealing assembly comprises a sealing seat, an end face sealing ring body and a circumferential surface sealing ring body. The sealing seat is fixed with the vehicle body covering part, the sealing seat is provided with a sealing end face and a sealing peripheral face, the end face sealing ring body forms sealing between the vehicle body covering part and the sealing end face, the vehicle-mounted equipment is provided with a sealing matching peripheral face, and the peripheral face sealing ring body forms sealing between the sealing peripheral face and the sealing matching peripheral face. When the relative positions of the vehicle-mounted equipment and the vehicle body covering part in the through hole penetrating direction have deviation, the sealing circumferential surface of the sealing seat and the sealing matching circumferential surface of the equipment can still be reliably sealed through the circumferential surface sealing ring body, so that the floating sealing assembly is not easily influenced by equipment installation errors, and reliable sealing is facilitated.
本发明涉及密封结构技术领域,具体涉及一种车身设备过孔密封结构,车身设备过孔密封结构包括车身覆盖件及车载设备,车身覆盖件上设有过孔,过孔处设有密封组件,密封组件包括密封座及端面密封圈体、周面密封圈体,密封座与车身覆盖件固定,密封座具有密封端面和密封周面,端面密封圈体在车身覆盖件与密封端面之间形成密封,车载设备设有密封配合周面,周面密封圈体在密封周面与密封配合周面之间形成密封,车载设备与车身覆盖件在过孔贯通方向上相对位置有偏差时,密封座的密封周面与设备的密封配合周面仍然可以通过周面密封圈体进行可靠密封,这样的浮动密封组件不容易受设备安装误差影响,有利于密封可靠。
