Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a vehicle pipeline separation and fixing bracket and an automobile. Background Technology

[0002] In modern automotive manufacturing, with the increasing electrification and intelligence of vehicles, the number of electrical wiring harnesses integrated inside automobiles has significantly increased, while fluid pipelines such as air conditioning and cooling systems have become increasingly complex. These wiring harnesses and water pipes typically need to be arranged along vehicle pillars (such as A-pillars, B-pillars, and C-pillars) and positioned using fixing devices to prevent displacement, wear, or loosening due to vibration and impact during vehicle operation, thus ensuring the safety and reliability of the entire vehicle. However, traditional fixing methods often use single clips or cable ties to bundle the wiring harnesses and water pipes together, leading to friction between the two during long-term operation. This can easily cause damage to the wiring harness sheath, short circuits, or scratches and leaks on the water pipe surface, posing significant safety hazards. Furthermore, existing fixing brackets are often functionally limited, only providing pipeline fixing and lacking efficient connection designs with the vehicle body structure. The installation process is cumbersome and fails to meet the high requirements of modern automotive production lines for assembly efficiency and maintainability. Especially in the interior assembly stage, exposed fixing brackets affect aesthetics and require additional shielding structures, increasing the number of parts and assembly steps. Utility Model Content

[0003] To address the aforementioned issues, the present invention aims to provide a vehicle-mounted pipeline separation and fixing bracket that is structurally sound, functionally integrated, easy to install, and safe and reliable. This bracket enables independent fixing of the wiring harness and water pipe, quick and detachable connection to the vehicle body pillar, and integrates decorative panel installation functionality.

[0004] In a first aspect, this utility model provides a vehicle pipeline separation and fixing bracket, comprising: a mounting plate;

[0005] The front side of the mounting plate is provided with a wire harness fixing part and a water pipe fixing part for fixing the wire harness and water pipe.

[0006] The mounting plate is provided with an assembly part on its rear side for detachably mounting the mounting plate to the vehicle body;

[0007] One end of the mounting plate is also provided with a decorative panel mounting part for mounting the decorative panel.

[0008] Furthermore, the assembly part is a plug-in protrusion extending outward from the rear side of the mounting plate; the cross-section of the plug-in protrusion is polygonal or elliptical.

[0009] The outer peripheral surface of the insertion protrusion is provided with a plurality of elastic snap-fit ​​protrusions spaced along the axial direction, and each snap-fit ​​protrusion is arranged to surround or partially surround the insertion protrusion in the circumferential direction.

[0010] Furthermore, a connecting arm extends forward from one end of the mounting plate;

[0011] The end of the connecting arm is connected to an assembly plate arranged perpendicular to the extension direction of the connecting arm, and the assembly plate and the mounting plate are respectively located on both sides of the connecting arm;

[0012] The decorative panel mounting section is located on the assembly plate.

[0013] Furthermore, a fixing ring is provided on the front surface of the mounting plate, and a cable tie is inserted through the fixing ring;

[0014] The fixing ring and the cable tie constitute the wire harness fixing part.

[0015] Furthermore, the inner wall of the fixing ring is provided with a plurality of anti-slip ribs distributed circumferentially.

[0016] Furthermore, the edge of the fixing ring is provided with rounded corners or elastic lips.

[0017] Furthermore, the water pipe fixing part includes an elastic annular body, and the annular body is provided with an axial opening;

[0018] One side of the opening extends to form a protrusion, and the other side extends to form an elastically deformable hook-shaped part;

[0019] The protrusion and the hook-shaped part are closed and locked by elastic engagement.

[0020] Furthermore, the hook-shaped portion includes a curved section and a locking end;

[0021] The curved section extends outward from the other side of the opening.

[0022] The locking end is located at the end of the curved section and bends inward;

[0023] The locking end is used to hook the protrusion to form an anti-disengagement latch.

[0024] Furthermore, the mounting plate is also provided with at least one reinforcing rib, which is located in the area between the wire harness fixing part and the water pipe fixing part.

[0025] In a second aspect, an automobile is provided, including a vehicle body and a vehicle pipeline separation and fixing bracket as described in any of the above technical solutions;

[0026] The vehicle body is provided with a docking part on the A-pillar, B-pillar or C-pillar;

[0027] The vehicle pipeline separation and fixing bracket is installed on the A-pillar, B-pillar, or C-pillar through the fitting connection between the assembly part and the docking part.

[0028] This utility model has the following advantages or beneficial effects:

[0029] 1. By setting up wiring harness fixing parts and water pipe fixing parts on the front side of the mounting plate for fixing the wiring harness and water pipe, the wiring harness and water pipe are physically separated in space. This effectively avoids safety hazards such as wear of the wiring harness insulation layer, short circuits, or scratches and leaks on the water pipe surface caused by mutual friction during vehicle operation, thereby improving the safety and reliability of the vehicle's electrical system and fluid pipelines. At the same time, the assembly part set on the rear side of the mounting plate allows the bracket to be detachably installed to the vehicle body pillar, facilitating quick installation and subsequent maintenance and replacement on the vehicle assembly line, thus improving assembly efficiency. In addition, a decorative panel mounting part is set at one end of the mounting plate for installing interior decorative panels. This not only achieves functional integration of the bracket and interior parts but also conceals the fixing structure, enhancing the aesthetics and integrity of the vehicle interior, achieving a unity of functionality and decoration.

[0030] 2. By designing the assembly part as an insertion protrusion extending outward from the rear side of the mounting plate, and designing its cross-section as a polygon or ellipse, the insertion protrusion cannot rotate freely after being inserted into the mounting hole of the vehicle body pillar. This effectively prevents the bracket from rotating circumferentially due to vibration during vehicle operation, significantly improving installation stability and positioning accuracy. At the same time, multiple elastic snap-fit ​​protrusions are arranged axially at intervals on the outer circumference of the insertion protrusion. Each snap-fit ​​protrusion is arranged circumferentially around or partially around the insertion protrusion. During insertion, the snap-fit ​​protrusion undergoes elastic deformation, and after being inserted into place, it returns to its original shape and forms a firm snap-fit ​​with the inner wall of the mounting hole, achieving self-locking fixation. The connection is reliable, the operation is simple, and the installation can be completed without additional tools, greatly improving assembly efficiency and connection strength.

[0031] 3. The water pipe fixing part is designed as a flexible annular body with an axial opening, allowing the annular body to open and facilitate quick installation and removal of the water pipe. The protrusion extending from one side of the opening and the elastically deformable hook-shaped part extending from the other side achieve a closed locking through elastic engagement, forming a self-locking pipe clamp structure. The water pipe can be fixed without additional tools, making the operation convenient. This structure has good adaptability to water pipes of different outer diameters. It relies on the elastic deformation of the annular body to achieve fastening, avoiding the cumbersome operation of traditional threaded fastening methods, and significantly improving assembly efficiency and sealing reliability.

[0043] Example 1

[0044] like Figure 1 and Figure 2As shown in the illustration, this utility model provides a vehicle-mounted pipeline separation and fixing bracket for use in the internal structure of automobiles. Its purpose is to achieve independent, orderly, and stable fixing of wiring harnesses and water pipes, avoiding mutual interference and improving assembly efficiency and overall vehicle safety. This vehicle-mounted pipeline separation and fixing bracket has a compact overall structure, is easy to install, and is highly versatile, suitable for installation on various pillar positions such as the A-pillar, B-pillar, or C-pillar of the vehicle body. Through modular design, the bracket integrates wiring harness fixing, water pipe fixing, and decorative panel connection functions, while possessing good structural strength and vibration resistance, meeting the usage requirements of automobiles under complex operating conditions.

[0045] The core structure of this vehicle-mounted pipeline separation and fixing bracket includes a main load-bearing component—mounting plate 1. Mounting plate 1 serves as the mounting base for all functional components in this invention. It is typically manufactured in one piece using high-strength engineering plastics through injection molding, exhibiting good dimensional stability, temperature resistance, and anti-aging properties. In other optional embodiments, mounting plate 1 can also be made of metal materials (such as aluminum alloy or stainless steel) through stamping or die casting to adapt to application scenarios requiring higher strength or higher temperature environments. Mounting plate 1 has two opposing main surfaces: a front side and a rear side. The front side of mounting plate 1 faces the vehicle interior space and is used to house functional structures for connecting to wiring harnesses and water pipes; the rear side of mounting plate 1 faces the vehicle body pillars and is used for fixed connection to the vehicle body.

[0046] On the front side of the mounting plate 1, there are wire harness fixing parts 2 and water pipe fixing parts 3 for fixing wire harnesses and water pipes. The wire harness fixing parts 2 and water pipe fixing parts 3 are spatially separated, forming a pipeline separation layout, which effectively avoids the risk of wear or leakage caused by friction and compression of wire harnesses and water pipes during operation. This separation design not only improves the safety of pipelines, but also facilitates later maintenance and repair. The wire harness fixing part 2 is used to clamp or bundle the electrical wire harness inside the vehicle, ensuring that it remains stable during vehicle operation and does not shake or fall off; the water pipe fixing part 3 is used to fix coolant pipes, air conditioning pipes or other fluid transportation pipes, preventing them from fatigue fracture or loosening of joints due to vibration.

[0047] A mounting portion 4 is provided on the rear side of the mounting plate 1, which is used to detachably install the mounting plate 1 to the A-pillar of the vehicle body. "Detachably installable" here means that the bracket can be quickly installed and removed by means of snap-fit, plug-in, or screw-in, facilitating vehicle assembly line operations and after-sales maintenance and replacement. In this embodiment, the mounting portion 4 is a plug-in protrusion 41 extending outward from the rear side of the mounting plate 1. This plug-in protrusion 41 forms an interference fit or elastic snap-fit ​​with the mating portion (i.e., mounting hole) on the A-pillar of the vehicle body. The cross-section of the plug-in protrusion 41 is polygonal or elliptical, preferably rectangular, D-shaped, or elliptical. This non-circular cross-section design effectively prevents the bracket from rotating circumferentially after installation, ensuring its stability during vehicle operation. Simultaneously, this non-circular structure provides a larger contact area, enhancing torsional resistance.

[0048] Multiple elastic snap-fit ​​protrusions 42 are axially spaced on the outer periphery of the insertion protrusion 41. These snap-fit ​​protrusions 42 elastically deform when inserted into the mounting holes on the vehicle body, and return to their original shape after full insertion, thus forming a firm snap-fit ​​connection with the inner wall of the mounting hole. Each snap-fit ​​protrusion 42 is arranged circumferentially around or partially around the insertion protrusion 41. It can be a complete annular protrusion or multiple arc-shaped segments distributed on the outer periphery of the insertion protrusion 41, forming a segmented snap-fit ​​structure. This design not only improves the reliability of the connection, but also achieves good adaptability within different tolerance ranges. The snap-fit ​​protrusions 42 are made of elastic material or have elastic deformation capability due to structural design. They can contract inward under force and return to their original position after release, realizing a "self-locking" function. The connection method between the assembly part 4 and the vehicle body is an adaptive connection, that is, the insertion protrusion 41 and the mating part (such as mounting hole, slot, etc.) on the vehicle body match each other in shape and size, ensuring sufficient connection strength and positioning accuracy after installation.

[0049] In addition, a decorative panel mounting part 5 is provided at one end of the mounting plate 1 for mounting the decorative panel. The decorative panel mounting part 5 not only performs the mechanical connection function, but also plays an aesthetic role in concealing the brackets and pipelines under the interior trim, thereby improving the visual cleanliness of the vehicle interior.

[0050] In this embodiment, a connecting arm 6 extends forward from one end of the mounting plate 1, forming a cantilever structure. An assembly plate 7 is connected to the end of the connecting arm 6. The assembly plate 7 is positioned perpendicular to the extension direction of the connecting arm 6, meaning it bends at a right angle relative to the connecting arm 6, forming an "L"-shaped spatial layout. The assembly plate 7 and the mounting plate 1 are located on opposite sides of the connecting arm 6, with one end connected to the mounting plate 1 and the other end connected to the assembly plate 7. These two are spatially staggered, allowing the decorative panel to be installed independently without affecting the fixed position of the main support. The decorative panel mounting part 5 is located on the assembly plate 7 and can be detachably connected to the decorative panel using snap-fit, slot, screw holes, or other means. In other optional embodiments, the decorative panel mounting part 5 can also be directly integrated into the end of the mounting plate 1, omitting the connecting arm 6 and the assembly plate 7 structure, suitable for installation environments with limited space.

[0051] Regarding the specific structure of the wire harness fixing part 2, in a preferred embodiment, a fixing ring is provided on the front surface of the mounting plate 1. This fixing ring is a partial structure protruding from the surface of the mounting plate 1, used for inserting cable ties. During operation, the wire harness is arranged and placed on the front side of the mounting plate 1, and then a plastic cable tie is passed through the fixing ring to secure the wire harness. The fixing ring and the cable tie together constitute the wire harness fixing part 2. This structure is simple, reliable, low-cost, and suitable for wire harnesses of different diameters. To further improve the fixing effect, the inner wall of the fixing ring is provided with multiple anti-slip ribs distributed circumferentially. These anti-slip ribs are strip-shaped protrusions, evenly distributed on the inner wall of the fixing ring. When the cable tie passes through, the anti-slip ribs generate frictional resistance with the outer surface of the cable tie, preventing the cable tie from loosening under long-term vibration. The number of anti-slip ribs can be set to 3 to 6 according to actual needs, with a height of 0.1 to 0.3 mm, providing sufficient friction without excessively increasing insertion resistance.

[0052] Meanwhile, the edges of the retaining ring are rounded or have elastic lips. The rounded corners at both ends of the retaining ring guide the cable ties to be inserted smoothly and prevent sharp edges from scratching the cable ties or the operator's fingers.

[0053] The elastic lip is a thin-walled structure that folds slightly inward towards the fixing ring, possessing a certain degree of elastic deformation capability. When the cable tie is inserted, the lip expands outward and springs back after insertion, applying a slight clamping force to the cable tie to further prevent loosening. This elastic lip can work in conjunction with the anti-slip ribs to significantly improve the reliability of the wire harness fixing, while also preventing scratches on the cable tie.

[0054] In a preferred embodiment, the water pipe fixing part 3 includes an elastic annular body 31. This annular body 31 surrounds the outer periphery of the water pipe to be fixed, forming a circumferential fixing. The annular body 31 has an axial opening, meaning a gap is left on its side, allowing it to elastically open radially. When the water pipe needs to be installed, an external force is applied to widen the opening, and the water pipe is placed inside the annular body 31. After the external force is released, the annular body 31 recovers its elasticity, firmly securing the water pipe.

[0055] Specifically, a protrusion 32 extends from one side of the opening, which is a columnar or block-shaped structure protruding outward from one end of the opening; a hook-shaped part 33 extends from the other side of the opening, which can be elastically deformable. The hook-shaped part 33 bends inward in a free state and can elastically engage with the protrusion 32, thereby closing and locking the annular body 31 to prevent it from accidentally opening during vibration.

[0056] Furthermore, the hook-shaped portion 33 includes a curved section 331 and a locking end 332. The curved section 331 extends outward from the other side of the opening, forming an arc-shaped structure with good elastic deformation capability. The locking end 332 is located at the end of the curved section 331 and bends inward to form a hook-shaped end similar to a "J" or "L". When the annular body 31 is closed, the locking end 332 is used to hook the protrusion 32, forming an anti-detachment latching structure. This anti-detachment latching structure can withstand dynamic loads such as bumps and impacts during vehicle operation, ensuring that the water pipe fixing part 3 always remains in a closed state.

[0057] To improve the overall structural rigidity and resistance to deformation, the mounting plate 1 is also provided with at least one reinforcing rib. The reinforcing rib is located in the area between the wire harness fixing part 2 and the water pipe fixing part 3, i.e., a longitudinal or transverse reinforcing rib is provided between the two functional components to connect them. The reinforcing rib not only disperses stress and prevents local deformation, but also improves the overall bending and torsional resistance. In other embodiments, the reinforcing rib may be distributed in a grid pattern, radially, or ring-shaped on the back or side of the mounting plate 1 to further enhance structural stability.

[0058] In one specific embodiment, the mounting plate 1, connecting arm 6, and assembly plate 7 adopt an integrated structural design, manufactured as a whole using high-strength engineering plastics through injection molding. This ensures the integrity of the structure and the reliability of the connection, avoiding the risk of loosening or breakage that can occur with multi-part assembly. This integrated structure includes the main mounting plate 1, the connecting arm 6 extending forward from one end of the mounting plate 1, and the assembly plate 7 located at the end of the connecting arm 6 and perpendicular to its extension direction. The three parts transition continuously without welding or splicing seams, significantly improving overall rigidity and durability. Specifically, the mounting plate 1, connecting arm 6, and assembly plate 7 all employ a double-layer plate structure, meaning each part consists of an outer plate and an inner plate, forming a hollow reinforced cavity. A certain distance is maintained between the outer and inner plates, and they are fixedly connected by multiple evenly distributed connecting ribs. These connecting ribs are arranged in a grid pattern or parallel along the plate surface, which not only enhances local compressive strength and prevents deformation under stress but also improves the structure's thermal insulation and noise reduction performance. The double-layer plate and connecting ribs together form a lightweight and high-strength support system, which reduces material usage and overall weight while ensuring load-bearing capacity, making it suitable for the trend of lightweight automotive development.

In other optional embodiments, the bracket can also be installed on the B-pillar or C-pillar, achieving a universal design. After installation, the wiring harness fixing portion 2 and water pipe fixing portion 3 on the front side of the bracket are used to fix the corresponding wiring harnesses and water pipes, respectively, while the decorative panel mounting portion 5 is used to connect the interior decorative panel, achieving a unity of function and aesthetics.
