Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile manufacturing, in particular to a pipeline hidden arrangement structure of an automobile front wall side plate. BACKGROUND

[0002] The front wall side plate of an automobile is an important part of the vehicle body, located between the engine compartment and the driver's cabin, and is a key area of the vehicle body structure. In this area, a large number of electrical harnesses, air conditioning pipelines and fluid conduits are arranged, and these pipelines need to be properly fixed, arranged and passed through the wall plate.

[0003] In the prior art, these pipelines are usually fixed by simple buckles, straps or supports, or directly hidden in the gap of sheet metal parts. This arrangement has many disadvantages: on the one hand, the fixing method is loose, or the installation and disassembly process is cumbersome, especially when the vehicle is being repaired, a lot of time is spent to disassemble and restore these pipelines, and the assembly and maintenance efficiency is low; on the other hand, the fixing effect is unstable, and the vibration during vehicle driving can cause the pipelines to loosen, rub and make noise, and even damage.

[0004] In addition, when the pipeline needs to pass through the front wall side plate into the driver's cabin, strict sealing treatment must be carried out to prevent rainwater, dust and noise in the engine compartment from entering the vehicle. The existing sealing structure, such as a simple rubber sheath or a sealing ring, is often complex to install, or the sealing reliability is not high, it is difficult to maintain long-term effective sealing under complex vibration conditions, and it is also difficult to achieve quick docking during assembly.

[0005] In summary, the existing pipeline arrangement method of the automobile front wall side plate generally lacks a set of integrated special structure that can realize quick fixing, hiding of the pipeline and efficient and reliable sealing when passing through the plate, resulting in low vehicle assembly efficiency, difficult post-maintenance, and poor protection and sealing effect of the pipeline.

[0006] Therefore, the present application proposes a pipeline hidden arrangement structure of an automobile front wall side plate to solve the problems of the prior art. SUMMARY

[0007] In view of the problems in the prior art that the pipeline hidden arrangement structure of the automobile front wall side plate is fixed, installed and disassembled, and the hiding and protection effect is poor, and the pipeline sealing reliability is low, the present application aims to provide a pipeline hidden arrangement structure of an automobile front wall side plate with improved structure to effectively solve the above problems.

[0008] The present application provides a pipeline hidden arrangement structure of an automobile front wall side plate, comprising: a wall plate, a first conduit, a quick release mechanism fixed to the wall plate, a second conduit, and a sealing mechanism.

[0009] The quick release mechanism is used to hide and fix the first conduit. The sealing mechanism is used to seal the second conduit and the perforation of the enclosure.

[0010] The quick release mechanism comprises a snap ring fixed on the outer periphery of the first conduit, a snap pin fixedly connected to the snap ring, a shell, a support plate slidably arranged in the shell, a buckle connected to the support plate, and a reset assembly connected to the support plate.

[0011] The reset assembly has a central shaft fixed on the support plate, a connecting plate rotationally connected around the central shaft, a cylinder fixed to the connecting plate, and a limiting block one and a limiting block two fixed to the shell.

[0012] Preferably, the sealing mechanism comprises a fixed seat fixed at the perforation of the enclosure, a female head fixed to the fixed seat, a male head connected to the end of the second conduit, a rubber ring installed in the male head, a rotating shaft arranged on the male head, and a lock catch rotationally connected around the rotating shaft. In the assembled relationship, the second conduit passes through the female head, and the male head is butted against the female head. The cylinder is used to slide along the profile surface of the limiting block one and the limiting block two, so as to control the support plate to switch between the locked position and the unlocked position under the pressing drive of the snap pin. The lock catch is used to engage the female head and press down the male head, so as to extrude the rubber ring to achieve sealing. The reset assembly further comprises a guide rod fixed to the shell, and a spring sleeved on the guide rod. The spring abuts against the support plate, and the spring is used to compress and store elastic potential energy when the support plate moves under force, so as to provide power for the unlocking action of the reset assembly.

[0013] Preferably, the buckle is extruded by the inner wall of the shell during the downward movement of the support plate. This extrusion structure causes the buckle to automatically move towards the middle, thereby achieving automatic engagement and clamping fixation of the snap pin.

[0014] Preferably, a V-shaped groove is formed in the bottom of the limiting block one. The V-shaped groove serves as a mechanical locking position and is used to be engaged by the cylinder in the locked position, so as to prevent the cylinder from accidentally sliding in a vibrating environment.

[0015] Preferably, as a specific unlocking method, when the snap pin is pressed again, the cylinder will slide out of the V-shaped groove along the specific unlocking slide path on the right side of the limiting block one and the limiting block two. At this time, the spring releases the elastic potential energy, pushes the support plate, and then drives the buckle to move upward and away from the snap pin, thereby completing the unlocking.

[0016] Preferably, the outer surface of the female head is provided with a strip-shaped groove and a ring-shaped groove. The lock catch is correspondingly provided with a protruding portion. During installation, the protruding portion is first inserted into place along the strip-shaped groove, and then rotated to be engaged in the ring-shaped groove, thereby achieving fast circumferential locking.

[0017] Preferably, the rubber ring just contacts the front end of the female head when the male head and the female head are connected and before the locking buckle engages the annular groove. This design ensures that the rubber ring can be effectively extruded and deformed to fill the sealing gap immediately when the locking buckle is pressed down.

[0018] Preferably, as a specific arrangement, the conduit is fixed in the space between the front wall side plate and the longitudinal beam by the quick release mechanism. This arrangement makes full use of the existing space between the vehicle body structure, effectively hides and protects the pipeline.

[0019] The present application has the following beneficial effects: 1. The present application, by setting the quick release mechanism, the mechanism hides the pipeline in the space between the front wall side plate and the longitudinal beam by the cooperation of the supporting plate, the buckle and the reset assembly, solves the problems of pipeline exposure, layout disorder and easy damage in the prior art, and achieves the technical effects of protecting the pipeline, improving the appearance of the whole vehicle and reasonably utilizing the internal space of the vehicle body.

[0020] 2. The present application, by setting the quick release mechanism and the reset assembly inside it, uses the mechanical principle of the cylinder sliding along the limiting block track and the spring reset to make the buckle realize the pressing locking and re-pressing unlocking functions of the pin, solves the problems of complex installation and disassembly, dependence on tools and inconvenient maintenance of the pipeline fixing mode in the prior art, and achieves the technical effect of improving the assembly and maintenance efficiency.

[0021] 3. The present application, by setting the sealing mechanism, uses the butt joint of the male head and the female head, and tightly extrudes the rubber ring by pressing down the rotating buckle, solves the problems of complex pipeline through plate sealing structure, unreliable sealing performance and easy entry of rain and dust into the vehicle in the prior art, and achieves the technical effects of good sealing effect, stable structure and effective dust and water prevention.
