一种燃油箱压力传感器低HC渗透固定支架
摘要：
本发明涉及一种燃油箱压力传感器低HC渗透固定支架,包括能够相互卡合的上固定支架、下固定支架，所述上固定支架、下固定支架的中部位置对应设置有装配孔，其中所述上固定支架一侧设置有限位部、下方底面设置有环形台阶，所述环形台阶下方两侧侧壁上设置卡合块，所述下固定支架上设置有回转凹槽，所述回转凹槽两侧侧壁上设置有与卡合块相互卡合的卡限组件。本发明通过设置限位部、限位块、限位螺柱以及卡限组件，和采用了将由PA12材质制成的上固定支架与HDPE材质制成的下固定支架相结合的方式，不仅实现了对油箱压力传感器固定的同时，还能够有效地降低了HC的渗透排放，以及满足了燃油箱的焊接与装配性能。
摘要（英）：

The invention relates to a low-HC-permeability fixing support frame for a pressure sensor of a fuel tank. The low-HC-permeability fixing support frame comprises an upper fixing support frame and a lower fixing support frame which can be engaged with each other, wherein assembly holes are correspondingly arranged at the middle positions of the upper fixing support frame and the lower fixing supportframe; a position-limiting part is arranged on one side of the upper fixing support frame; an annular step is arranged at the bottom surface of the lower part of the upper fixing support frame; engaging blocks are arranged on two side walls of the lower part of the annular step; the lower fixing support frame is provided with a rotary groove; and two side walls of the rotary groove are provided with locking limiting assemblies engaged with the engaging blocks. Through the arrangement of the position-limiting part, position-limiting blocks, a position-limiting stud and the locking limiting assemblies, and by adopting a method of combining the upper fixing support frame made of PA12 materials with the lower fixing support frame made of HDPE materials, the low-HC-permeability fixing supportframe for the pressure sensor of the fuel tank not only achieves the fixing of the pressure sensor of the fuel tank, but also effectively reduces the HC permeation and emission and satisfies the welding and assembly performance of the fuel tank.
