Description
Technical field
The utility model belongs to vehicle body sheet metal technical field, refers to that one crosses panel beating pipeline fixed sheath especially.
Background technique
Heater core belongs to a part for car air conditioner heating plant.By heater turnover water pipe, by the engine exhaust heat water thermal release flowed through, realize heating in car by HVAC and air channel.
The sebific duct of warm braw turnover water pipe connecting engine water pipe and evaporator core, realizes the water circulation of engine exhaust heat water heating.
As shown in Figure 1, because heater core 3 is in HVAC, be arranged in operator cabin, heater cores hot water source motor is arranged in again in engine bin, and the two connects needs by warm braw turnover water pipe through vehicle body sheet metal 1.In order to reach car load sealing requirements, preventing heater core 3 by panel beating vibration incised wound simultaneously, usually using rubber sheath 2 to cut from panel beating for the protection of wire harness herein.
As shown in Figures 2 and 3, tradition crosses body platform stamping holes, because vehicle body sheet metal 1 is steel plate; air-conditioning duct mostly is aluminum pipe, and pipeline exists the risk cut by panel beating, and plays the effect of protection pipeline by the rubber sheath be embedded on panel beating; prevent vehicle body sheet metal 1 from being cut by pipeline, cause disclosure risk.Panel beating mode crossed by traditional sheath: rubber sheath 2 is with rectangular recess 4, and vehicle body sheet metal 1 embeds in rectangular recess 4, by assembling by force, vehicle body sheet metal 1 is in rectangular recess 4, thus reaches fixing and seal action
Traditional pipeline fixed sheath, generally perforate in the middle part of rubber sheath, pipeline passes perforate and compressing rubber, realizes the fixing of pipeline; The rectangular recess that edge designs can make vehicle body sheet metal embed, the mode coordinated with the rectangular recess of rubber sheath by vehicle body sheet metal realizes fixing, and reaches the effect of sealing simultaneously.And in vehicle traveling process, there is pitch, particularly automobile is when high speed or mountain area road conditions travel, car load vibration causes rubber sheath to get loose or pipeline displacement, causes vehicle sealing to decline, also there is pipeline and vehicle body sheet metal interferes the risk cut after Long-Time Service.
The shortcoming of traditional rubber sheath is:
Rubber sheath and pipeline rely on and extrude fixing, assemble improper or Long-Time Service with ageing of rubber, there is sealing decline problem.
Rectangular recess and the vehicle body sheet metal of rubber sheath are fixed, and by vertical shearing force during vehicle travels, the size of power changes with Vehicular vibration, accelerates ageing of rubber, easily comes off.
Rubber sheath is full rubber structure, and without positioning hole, bulk strength is low, and external force factor may cause pipeline to offset, and interferes worn-off problem with vehicle body sheet metal.
