Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a concealed pipeline arrangement structure for the front side panel of an automobile. Background Technology

[0002] The front side panel of a car is an important component of the vehicle body, located between the engine compartment and the passenger compartment, and is a critical area of ​​the body structure. This area houses numerous electrical wiring harnesses, air conditioning pipes, and fluid conduits, all of which need to be properly secured, arranged, and pass through the panel.

[0003] In existing technologies, these pipelines are typically secured using simple clips, cable ties, or brackets, or directly concealed within gaps in sheet metal components. This arrangement has several drawbacks: firstly, the securing method is relatively loose, or the installation and disassembly process is cumbersome, especially during vehicle maintenance, requiring significant time to disassemble and restore these pipelines, resulting in low assembly and maintenance efficiency; secondly, the securing effect is unstable, and vibrations during vehicle operation can easily cause the pipelines to loosen, produce friction noises, or even be damaged.

[0004] Furthermore, when pipelines need to pass through the front bulkhead side panel into the passenger compartment, strict sealing measures must be implemented to prevent rainwater, dust, and noise from the engine compartment from entering the vehicle. Existing sealing structures, such as simple rubber sleeves or sealing rings, are often complex to install or have low sealing reliability, making it difficult to maintain a long-term effective seal under complex vibration conditions, and also making it difficult to achieve quick connection during assembly.

[0005] In summary, existing methods for arranging pipelines on the front side panels of automobiles generally lack an integrated, dedicated structure that can quickly fix and conceal pipelines while ensuring efficient and reliable sealing when they pass through the panels. This results in low vehicle assembly efficiency, difficult maintenance, and poor protection and sealing of the pipelines.

[0006] Therefore, this utility model proposes a concealed pipeline arrangement structure for the front side panel of an automobile to address the shortcomings of the prior art. Summary of the Invention

[0007] In view of the problems of cumbersome and time-consuming pipe fixing, installation and disassembly, poor concealment and protection effect, and low reliability of pipe penetration sealing in the existing automotive front side panel concealed pipeline arrangement structure, this utility model aims to provide an improved automotive front side panel concealed pipeline arrangement structure that can effectively solve the above problems.

[0008] This utility model provides a concealed pipeline arrangement structure for the front side panel of an automobile, including: a panel; a first conduit; a quick-release mechanism fixed to the panel; a second conduit; and a sealing mechanism.

[0009] The quick-release mechanism is used to conceal and secure conduit one. The sealing mechanism is used to seal the perforation between conduit two and the surrounding plate.

[0010] The quick-release mechanism includes a retaining ring fixed to the outer periphery of the conduit, a retaining pin fixedly connected to the retaining ring, a housing, a support plate slidably disposed within the housing, 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 a support plate, a connecting plate rotatably connected around the central shaft, a cylinder fixed to the connecting plate, and two limiting blocks fixed to the outer shell.

[0012] Preferably, the sealing mechanism includes a fixing seat fixed at the perforation of the enclosure plate, a female head fixed to the fixing seat, a male head connected to the two ends of the conduit, a rubber ring installed inside the male head, a rotating shaft on the male head, and a latch rotatably connected around the rotating shaft. In the combined configuration, the second conduit passes through the female head, and the male head mates with the female head. The cylinder is used to slide along the contour surfaces of the first and second limiting blocks to control the support plate to switch between a locked and unlocked position under the pressing drive of the locking pin. The latch is used to engage the female head and press down the male head to compress the rubber ring to achieve a seal. The reset assembly also includes a guide rod fixed to the housing and a spring sleeved on the guide rod. The spring abuts against the support plate and is used to compress and store elastic potential energy when the support plate is moved under force, providing power for the unlocking action of the reset assembly.

[0013] Preferably, the buckle is squeezed by the inner wall of the outer shell as the support plate moves downward. This squeezing structure causes the buckle to automatically move towards the center, thereby achieving automatic engagement and clamping fixation of the locking pin.

[0014] Preferably, the bottom of the limiting block one is provided with a V-shaped groove. The V-shaped groove serves as a mechanical locking position, used to engage the cylinder in the locked position to prevent the cylinder from accidentally sliding under vibration.

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

[0016] Preferably, the outer surface of the female connector is provided with a strip-shaped groove and an annular groove. The locking buckle is correspondingly provided with a protruding part. During installation, the protruding part is first inserted into the strip-shaped groove, and then rotated to engage with the annular groove, achieving rapid circumferential locking.

[0017] Preferably, when the male and female connectors are mated, and before the locking buckle engages the annular groove, the front end of the rubber ring is in contact with the front end of the female connector. This design ensures that when the locking buckle is pressed down, the rubber ring is immediately and effectively compressed and deformed, filling the sealing gap.

[0018] Preferably, as a specific arrangement, the conduit is fixed in the space between the front bulkhead side panel and the longitudinal beam using a quick-release mechanism. This arrangement makes full use of the existing space between the vehicle body structures, achieving effective concealment and protection of the pipeline.

[0019] This utility model has the following beneficial effects: 1. This utility model, by setting up a quick-release mechanism, utilizes the coordinated work of the support plate, buckle and reset component to hide and fix the pipeline in the space between the front side panel and the longitudinal beam, which solves the problems of exposed pipeline, messy layout and easy damage in the prior art, and achieves the technical effect of protecting pipeline, improving the overall aesthetics of the vehicle and making reasonable use of the interior space of the vehicle body.

[0020] 2. This utility model, by setting up a quick-release mechanism and its internal reset component, utilizes the mechanical principle of the cylinder sliding along the limit block track and the spring reset, so that the buckle can realize the functions of pressing and locking the locking pin and pressing again to unlock it. This solves the problems of complex installation and disassembly, reliance on tools, and inconvenient maintenance of pipeline fixing methods in the prior art, and achieves the technical effect of improving assembly and maintenance efficiency.

[0021] 3. This utility model solves the problems of complex pipeline through-plate sealing structure, unreliable sealing performance, and easy entry of rainwater and dust into the vehicle by setting a sealing mechanism, using the male and female heads to connect, and pressing down with a rotating lock to tightly compress the rubber ring. It achieves the technical effect of good sealing effect, stable structure, and effective dust and water protection. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0025] Please refer to Figures 1 to 4 This utility model provides a concealed pipeline arrangement structure for the front side panel of an automobile, which aims to solve the problems of exposed pipelines, easy damage, inconvenient installation and maintenance, and insufficient sealing reliability when pipelines pass through the panel in the prior art.

[0026] like Figure 1 As shown, the concealed pipeline arrangement structure of the front side panel of the automobile includes a panel 1, a conduit 3, a quick-release mechanism 2 fixed to the panel 1, a second conduit 5, and a sealing mechanism 4 for sealing the perforation between the second conduit 5 and the panel 1.

[0027] Reference Figures 1 to 3 The quick-release mechanism 2 includes a housing 21, a support plate 22 slidably disposed within the housing 21, a buckle 23 connected to the support plate 22, and a reset assembly 24 connected to the support plate 22. The quick-release mechanism 2 also includes a retaining ring 26 fixed to the outer periphery of the first guide tube 3, and a retaining pin 25 fixedly connected to the retaining ring 26. The buckle 23 is used to engage the retaining pin 25. The reset assembly 24 includes a central shaft 242 fixed to the support plate 22, a connecting plate 241 rotatably connected around the central shaft 242, a cylinder 243 fixed to the connecting plate 241, a first limiting block 244 and a second limiting block 245 fixed to the housing 21, a guide rod 247 fixed to the housing 21, and a spring 246 sleeved on the guide rod 247.

[0028] Reference Figure 1 and Figure 4The sealing mechanism 4 includes a fixing seat 46 fixed at the through hole of the enclosure plate 1, a female head 45, a male head 41, a rubber ring 42 fixed to the fixing seat 46, a rotating shaft 43 set on the male head 41, and a lock 44; the second conduit 5 passes through the female head 45, the male head 41 is connected to the end of the second conduit 5 and docks with the female head 45, the rubber ring 42 is installed in the male head 41, and the lock 44 is rotatably connected around the rotating shaft 43.

[0029] Reference Figure 2 and Figure 3 The reset assembly 24 has a central shaft 242 fixed on the support plate 22, a connecting plate 241 rotatably connected around the central shaft 242, a cylinder 243 fixed to the connecting plate 241, and limiting blocks 244 and 245 fixed to the outer shell 21. The reset assembly 24 also has a guide rod 247 fixed to the outer shell 21, and a spring 246 sleeved on the guide rod 247 and abutting against the support plate 22. Meanwhile, a buckle 23 is connected to the support plate 22, which is slidably disposed inside the outer shell 21. The cylinder 243 is used to slide along the contour surface of the limiting blocks 244 and 245. During the downward movement of the support plate 22, the buckle 23 is subjected to the inner wall of the outer shell 21. The compression causes the cylinder 243 to move towards the center, thus engaging the locking pin 25. This cam-track type engagement structure ensures that when the locking pin 25 is pressed for the first time, the cylinder 243 moves and engages in the V-shaped groove at the bottom of the limiting block 1 244. The spring 246 is compressed and stores elastic potential energy, and the buckle 23 closes and clamps the locking pin 25 to lock it in place. When the locking pin 25 is pressed again, the cylinder 243 will slide out of the V-shaped groove along the right side of the limiting block 1 244 and the limiting block 245. The spring 246 releases elastic potential energy, causing the support plate 22, the connecting plate 241, and the buckle 23 to move upward and away from the locking pin 25, thus unlocking the conduit 1 3, which is arranged in the space between the front side panel and the longitudinal beam using the quick-release mechanism 2.

[0030] As a preferred embodiment, refer to Figures 2 to 4The reset assembly 24 also includes a guide rod 247, which is fixed to the outer shell 21. A spring 246 is sleeved on the guide rod 247 and abuts against the support plate 22. The spring 246 is used to compress and store elastic potential energy when the support plate 22 moves. As the support plate 22 moves downward along the inside of the outer shell 21, the latch 23 is squeezed by the inner wall of the outer shell 21 and moves towards the center to achieve engagement with the latch 25. The bottom of the limiting block 1 244 is provided with a V-shaped groove, which is used to engage the cylinder 243 in the locked position to achieve mechanical locking. The contour surfaces of the limiting block 1 244 and the limiting block 245 together define the sliding path of the cylinder 243, and the path includes the V-shaped groove. The groove, and the unlocking slide located on the right side of the V-groove, after the cylinder 243 slides out of the V-groove, the spring 246 releases elastic potential energy to drive the buckle 23 to move upward and away from the locking pin 25. The outer surface of the female head 45 is provided with a strip groove and an annular groove. The latch 44 is provided with a protruding part. The protruding part of the latch 44 is used to move along the strip groove of the female head 45 and rotate to engage with the annular groove. The rubber ring 42 is installed in the male head 41, and in the state of the male head 41 and the female head 45 docking, and before the latch 44 engages with the annular groove, the rubber ring 42 just contacts the front end of the female head 45. The guide tube 3 is fixed by the quick release mechanism 2 and arranged in the space between the front side plate and the longitudinal beam.

[0031] The implementation principle of this application embodiment is as follows: Workers conceal the wiring in the front side panel 1 of the vehicle. The vehicle has dedicated wiring harness channels inside the front side panel. These channels are integrally formed with the body sheet metal, allowing the wiring harness and other cables to be hidden inside the vehicle body. This avoids occupying extra space and provides good protection. Alternatively, the space between the front side panel and the longitudinal beam can be used to arrange the wiring. The conduit 3 is quickly fixed in place using the quick-release mechanism 2, preventing it from being exposed. A retaining ring 26 is fixed to the conduit 3, and the retaining ring 26 is fixedly connected to a retaining pin 25. During installation, the worker aligns the retaining pin 25 with the middle of the two clips 23 and presses it, pushing the support plate 22 to move, further driving the reset assembly. 24. Spring 246 is compressed and stores elastic potential energy along the direction of guide rod 247. Cylinder 243 moves along the upper surface of limit block 1 244, thereby driving connecting plate 241 to rotate around the central axis 242 fixed on support plate 22. Limit block 1 244 has a V-shaped groove at the bottom. When cylinder 243 moves into the V-shaped groove, it is locked. At the same time, the two buckles 23 are also squeezed by the outer shell 21 during the downward movement, thus moving towards the middle and locking the pin 25. When disassembling, just press it again, and cylinder 243 will slide out along the right side of limit block 1 244 and limit block 2 245, driving the two buckles 23 to move upward and away, and the originally locked pin 25 can be released, completing the unlocking.

[0032] Where pipelines pass through the vehicle body, such as the front side panel, sealing is required to prevent rainwater and dust from entering the vehicle. This can be achieved through a sealing mechanism 4. The male connector 41 is connected to the conduit 5 that needs to pass through the panel. The operator first passes the conduit 5 through the channel in the female connector 45 and the fixing seat 46. A rubber ring 42 is installed inside the male connector 41. Then, the male connector 41 is connected to the female connector 45. The protruding part of the latch 44 installed inside the male connector 41 moves along the strip groove set on the female connector 45. When it moves to the annular groove set on the female connector 45, it stops and rotates 90 degrees. The protruding part of the latch 44 fits against the annular groove, and a preliminary engagement is achieved. The rubber ring 42 is in contact with the front end of the female connector 45. At this time, the latch 44 is rotated so that it rotates around the pivot 43 and is pressed down. The latch 44 fits tightly against the annular groove set on the female connector 45 and drives the male connector 41 to squeeze the rubber ring 42, thereby achieving a seal.
