The invention discloses an automotive firewall and sound insulation pad fixing fastener. The automotive firewall and sound insulation pad fixing fastener comprises a mounting hole, a fastener body and a connecting portion arranged at the fastener body. The fastener is pre-mounted on a noise insulation pad through the connecting portion and a straight welding screw welded to a firewall penetrates through the mounting hole and fixes the sound insulation pad to the firewall through a fixing portion arranged at the fastener body. The fastener is pre-mounted on the noise insulation pad through the connecting portion arranged at the fastener body and then the straight welding screw welded to the firewall can directly penetrate through the mounting hole arranged in the fastener body and can be in firm connection through the fixing portion arranged at the fastener body when the sound insulation pad is laid on the firewall. Compared with a spirally-plugging fastener in the prior art, the automotive firewall and sound insulation pad fixing fastener is simple in assembly process, capable of saving spirally-plugging fastener taking time and omitting spirally-plugging fastener taking operations and high in assembly efficiency.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to a buckle for fixing a firewall and a sound insulation pad of an automobile. Background technique [0002] The sound insulation pad installed on the firewall of the car is used to absorb heat and noise from the engine, and has the functions of heat insulation and vibration isolation, so as to ensure a quiet and comfortable driving environment in the cab and improve ride comfort. [0003] The sound insulation pad generally adopts a double-layer structure of "hard layer material + soft layer material", and its fixation with the firewall is realized by screw plug buckle. figure 1 As shown, the firewall 1' is equipped with a direct welding screw 11', the direct welding screw 11' passes through the through hole 21' of the sound insulation pad 2', and the screw plug buckle 3' penetrates the direct welding screw from the side close to the sound insulation pad 2'. screw 11', and is cl...
