Description

Technical Field

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

[0002] During the assembly of a car frame, the frame is typically fixed together with the left and right longitudinal beams and multiple crossbeams using riveting or bolting. The internal space formed by these longitudinal and crossbeams constitutes a U-shaped channel for laying various pipelines. However, during vehicle operation, the pipelines experience continuous friction with the flanges of the crossbeams. Since the flanges of the crossbeams usually have sharp edges, they can easily cut the outer sheath of the pipelines. This wear can cause electrical problems such as insulation failure and low-voltage power outages, and in severe cases, it can even lead to vehicle fires, posing a significant safety hazard.

[0003] Currently, there are various pipeline fixing solutions on the market, such as the automotive pipeline fixing bracket disclosed in CN206099189U. This technical solution involves creating through holes in the fixing bracket and using cable ties to bind the pipeline to the bracket. However, this solution has significant drawbacks: First, both pipeline installation and removal require tightening or cutting the cable ties, making the process cumbersome and inconvenient to maintain; second, the fixing reliability depends entirely on the quality of the cable ties themselves, posing a single point of failure risk due to cable aging or breakage; third, the hard contact edge between the pipeline and the bracket's through hole is prone to wear, still posing a risk of cutting the wiring harness. Furthermore, existing technologies are difficult to adapt to the fixing needs of pipelines of different specifications, lacking flexibility and versatility. Utility Model Content

[0004] The main purpose of this utility model is to propose a pipeline fixing device, which aims to avoid pipeline wear and improve the convenience of installation and the reliability of fixing.

[0005] To achieve the above objectives, the pipeline fixing device proposed in this utility model includes: The clamping part has a clamping groove formed on one side, and the end of the crossbeam facing the longitudinal beam has a flange, and the clamping groove is used to cover the flange. A fixing part is provided on the other side of the clamping part. There are multiple fixing parts, which are spaced apart along the extension direction of the clamping part. Each fixing part has a fixing groove located in the wire passage. The pipeline is used to be inserted into the fixing groove from the opening of the fixing groove.

[0006] In one embodiment, the wall of the clamping groove forms a locking block, and the crossbeam has a locking groove. When the clamping groove covers the flange, the locking block engages with the locking groove.

[0007] In one embodiment, one side of the card block is chamfered.

[0008] In one embodiment, the two opposite walls of the clamping groove are a first groove wall and a second groove wall, the locking block is formed on the first groove wall, and the second groove wall has an anti-air hole corresponding to the position of the locking block.

[0009] In one embodiment, any two adjacent fixing parts are connected by a connecting block.

[0010] In one embodiment, the fixing groove is a C-shaped groove.

[0011] In one embodiment, the opening arc length of the fixing groove is one-third of its complete circumference.

[0012] In one embodiment, the pipeline fixing device is a one-piece molded component.

[0013] In one embodiment, the multiple fixing slots may have the same or different dimensions.

[0014] In one embodiment, the plurality of fixed slots include at least two different widths of slots.

[0015] The technical solution of this utility model is to use a clamping groove to cover the flange of the crossbeam and use a fixing groove to directly insert the pipeline, without relying on cable ties for fixation. This not only avoids friction damage between the pipeline and the sharp flange, but also simplifies the installation and maintenance operation and improves the fixation reliability.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0023] In existing technologies, during the assembly of a car frame, longitudinal beams and crossbeams are connected by riveting or bolting to form an internal space that serves as a pipeline channel. When the vehicle is running, friction occurs between the pipelines and the flanges of the crossbeams, leading to insulation failure or fire risks. Current solutions use fixed brackets and cable ties to bind the pipelines, which presents challenges such as inconvenient operation, the risk of cable ties aging and breaking, and wear and tear from the hard contact between the pipelines and the brackets.

[0024] To address the aforementioned issues and the potential friction hazards arising from the contact path between pipelines and sharp flanges, traditional cable ties pose a risk of single-point failure. A solution is needed to eliminate the friction source and improve fixation reliability. Analysis of pipeline fixation failure modes reveals that direct contact with the flanges is the primary cause of wear, necessitating the construction of a physical isolation structure. Furthermore, traditional binding methods rely on the strength of the cable ties, requiring the design of a fixation mechanism that eliminates the need for auxiliary components. Based on this, a solution is proposed that the pipeline be confined within the passageway, and that distributed fixation points adapt to different pipeline routes.

[0025] Please refer to Figures 1 to 3 This application proposes a pipeline fixing device 100 for fixing pipelines in the cable passage 5 formed between the crossbeam 3 and the longitudinal beam 4 of an automobile. The pipeline fixing device 100 includes a clamping part 1 and a fixing part 2. A clamping groove 11 is formed on one side of the clamping part 1. The end of the crossbeam 3 facing the longitudinal beam 4 has a flange 31, and the clamping groove 11 is used to cover the flange 31. The fixing part 2 is disposed on the other side of the clamping part 1. There are multiple fixing parts 2, and the multiple fixing parts 2 are spaced apart along the extension direction of the clamping part 1. The fixing part 2 has a fixing groove 21, which is located in the cable passage 5. The pipeline is used to be inserted into the fixing groove 21 from the groove opening.

[0026] The clamping part 1 is a component used to connect with the flange 31 of the crossbeam 3. The contour of its clamping groove 11 matches the shape of the flange 31. For example, when the flange 31 is C-shaped, the clamping groove 11 can be designed as an inverted C-shape. The covering effect of the clamping groove 11 can cover the sharp edge of the flange 31 and block the contact path between the pipeline and the flange 31. The fixing part 2 is a structure used to constrain the pipeline. The opening direction of the fixing groove 21 can face the inside of the cable passage 5, which facilitates the lateral insertion of the pipeline. The spaced arrangement of multiple fixing parts 2 allows for flexible selection of fixing positions according to the number and direction of the pipeline. The open design of the fixing groove 21 means that the groove has a lateral opening, such as a C-shaped groove or a U-shaped groove. The pipeline can enter the groove by radial compression or lateral sliding. The opening size of the groove can be slightly smaller than the outer diameter of the pipeline, and self-locking fixation is achieved by utilizing the elasticity of the material.

[0027] Specifically, the clamping part 1 covers the flange 31 of the crossbeam 3 through the clamping groove 11, fixing the device to the end of the crossbeam 3, so that the fixing part 2 extends into the inside of the cable passage 5. After the pipeline is inserted laterally from the opening of the fixing groove 21, it is constrained within the fixing groove 21, avoiding contact with the flange 31. Multiple fixing parts 2 are arranged at intervals along the extension direction of the clamping part 1, forming multiple independent fixing points, which can simultaneously fix multiple pipelines or different sections of a single pipeline. The covering and fixing of the flange 31 by the clamping groove 11 and the constraint of the pipeline by the fixing groove 21 work together to construct a dual fixing mechanism.

[0028] Compared to existing technologies, CN206099189U uses through holes and cable ties for fixing, requiring additional binding operations for pipeline installation. This solution, however, achieves quick pipeline connection through the open design of the fixing groove 21, eliminating the need for auxiliary tools. Existing technologies suffer from wear due to the hard contact between the pipeline and the support through holes; this solution eliminates the friction source by fixing the pipeline within the fixing groove 21. Traditional solutions rely on the tensile strength of the cable ties, posing a risk of single-point failure; this solution improves system reliability by distributing the load through the distributed fixing parts 2.

[0029] Through the above technical solutions, this application can eliminate direct contact between pipelines and the flange 31 of the crossbeam 3, avoiding damage to the insulation layer caused by friction; the snap-fit ​​fixing groove 21 simplifies pipeline installation steps and improves maintenance efficiency; the distributed fixing point design enhances adaptability to different pipeline layouts and reduces the risk of single-point failure.

[0030] In one embodiment, there are five fixing parts 2, and each of the five fixing parts 2 forms a fixing groove 21, which can install five pipelines. In other embodiments, the number of fixing parts 2 can be two, seven, ten or other numbers, and this specification does not limit this.

[0031] Please refer to Figure 4 In one embodiment, the groove wall of the clamping groove 11 forms a locking block 1111, and the crossbeam 3 has a locking groove 32. When the clamping groove 11 covers the flange 31, the locking block 1111 and the locking groove 32 engage and cooperate.

[0032] The locking block 1111 refers to a protruding structure extending from the inner wall of the clamping groove 11, and its cross-sectional shape can be trapezoidal or rectangular. The locking groove 32 refers to a recessed structure opened in the area of ​​the flange 31 of the crossbeam 3, and its size forms a clearance fit with the locking block 1111. The fit between the locking block 1111 and the locking groove 32 forms a physical limit when the clamping part 1 covers the flange 31, preventing the clamping part 1 from shifting.

[0033] Specifically, when the clamping groove 11 completely covers the flange 31 of the crossbeam 3, the locking block 1111 is squeezed by the flange 31 and undergoes elastic deformation until the locking block 1111 is embedded in the preset locking groove 32 of the crossbeam 3. This engagement method adds a mechanical locking function to the clamping force, so that even if the clamping part 1 undergoes slight deformation due to vibration, the locking block 1111 can still maintain the engagement state with the locking groove 32.

[0034] Through the above technical solution, this application effectively prevents the clamping part 1 from loosening due to vehicle vibration and avoids friction between the pipeline and the flange 31 of the crossbeam 3. The rigid constraint formed by the snap-fit ​​significantly improves the torsional resistance of the fixing device, ensuring the positional stability of the pipeline under complex working conditions. This structure achieves rapid installation while eliminating the failure risk of cable tie aging and breakage in traditional binding methods.

[0035] Please refer to Figure 6 In one embodiment, one side of the card block 1111 is chamfered.

[0036] The chamfering refers to the beveling or rounding of the edge of the locking block 1111, which can be achieved through machining or injection molding. This design reduces local stress concentration when the locking block 1111 contacts the slot 32 during assembly by changing the geometry of its edge.

[0037] Specifically, the chamfered structure forms a guide slope when the locking block 1111 contacts the locking slot 32, allowing the locking block 1111 to slide into the locking slot 32 along the slope. During assembly, the chamfer guides the contact surfaces of the locking block 1111 and the locking slot 32 to gradually fit together, avoiding jamming caused by sharp edges. At the same time, the chamfer changes the contact area between the locking block 1111 and the locking slot 32 from point contact to surface contact, dispersing the friction and impact forces during assembly, thereby reducing the risk of wear on the contact surfaces.

[0038] Through the above technical solution, this application achieves smooth assembly of the card block 1111 and the card slot 32, reduces assembly resistance, and effectively avoids wear on the contact surface caused by sharp edges, thereby improving the reliability and service life of the card engagement.

[0039] Please refer to Figure 5 In one embodiment, the two opposite walls of the clamping groove 11 are a first groove wall 111 and a second groove wall 112, a locking block 1111 is formed on the first groove wall 111, and a clearance hole 1121 is provided on the second groove wall 112 corresponding to the position of the locking block 1111.

[0040] The clearance hole 1121 refers to a through hole structure provided in the second groove wall 112, which can be formed by machining the ejector pin position of the injection mold. Its spatial dimensions are greater than or equal to the projected dimensions of the clamping block 1111. This hole provides physical space for the clamping block 1111 to move during mold demolding, avoiding interference between the clamping block 1111 and the mold cavity. The two opposite groove walls of the clamping groove 11 refer to the two opposite side walls that constitute the clamping groove 11. This design ensures that the clamping block 1111 and the clamping groove 32 form an effective engagement, while eliminating motion interference during mold demolding through the clearance hole 1121.

[0041] Specifically, during the injection molding process, when the mold core exits from the clamping groove 11, the locking block 1111 gains lateral displacement space due to the presence of the clearance hole 1121, thereby preventing the locking block 1111 from mechanically colliding with the mold.

[0042] Through the above technical solution, this application effectively solves the demolding interference problem during injection molding of the card block 1111, enabling the clamping part 1 of the card block 1111 to be mass-produced using conventional molds.

[0043] In one embodiment, the shape of the flange 31 matches the shape of the clamping groove 11. In this embodiment, the flange 31 is preferably C-shaped, and correspondingly, the clamping groove 11 is inverted C-shaped to facilitate the clamping groove 11 covering the flange 31. In other embodiments, the flange 31 can also be a straight edge or other shapes, which will not be elaborated upon here. By matching the shape of the flange 31 with the shape of the clamping groove 11, it can be ensured that the clamping groove 11 completely covers the flange 31, increasing the stability of the connection.

[0044] In one embodiment, any two adjacent fixing parts 2 are connected by a connecting block 6.

[0045] The connecting block 6 refers to the transition structure that connects adjacent fixing parts 2. Specifically, it can be implemented as a one-piece structure using injection molding or stamping, and its width and thickness can be adjusted according to the spacing between the fixing parts 2 and the stress requirements. This structure restricts the relative displacement between adjacent fixing parts 2 through physical connection, ensuring spacing stability. The fixing part 2 refers to the support unit with a fixing groove 21. Specifically, the connecting block 6 between adjacent fixing parts 2 rigidly connects them through a laterally extending plate-like or strip-like structure. When the pipeline is inserted into the fixing groove 21, the connecting block 6 can effectively suppress the lateral displacement of the fixing parts 2 caused by vibration or external force, and prevent the pipeline from loosening due to the widening of the gap between the fixing grooves 21.

[0046] Through the above technical solution, this application solves the problem of insufficient connection stability between adjacent fixing parts 2, ensuring that multiple fixing parts 2 maintain a stable spacing under dynamic working conditions. At the same time, the integral structure enhances the deformation resistance of the fixing device, avoiding deformation of the fixing groove 21 due to local stress, thereby extending the service life of the device.

[0047] In one embodiment, the fixing groove 21 is a C-shaped groove.

[0048] The C-groove refers to a groove structure with an arc-shaped opening, which can be achieved using injection molding. The arc length of the opening accounts for one-third of the complete circumference. This structure allows the groove wall to slightly expand when the pipeline is inserted through the elastic deformation space at the opening, and then springs back to form a wrapping fixation after insertion.

[0049] Specifically, the arc-shaped opening of the C-groove guides the pipeline tangentially into the groove, avoiding rigid friction between the pipeline and the groove edge. The elastic deformation space created at the opening causes the groove wall to expand during the clamping process, and the groove wall rebounds and recovers after the pipeline enters, forming a protective enclosure for the pipeline. Compared to a closed groove, this structure reduces stress concentration at the contact surface between the pipeline's outer wall and the groove, lowering the risk of surface wear under long-term vibration environments.

[0050] Through the above technical solution, this application achieves rapid installation and disassembly of pipelines, reducing maintenance costs. The stress distribution at the contact surface between the pipeline and the tank is more uniform, reducing surface wear caused by localized friction under vibration conditions and improving fixing reliability.

[0051] In one embodiment, the opening arc length of the fixing groove 21 is one-third of its complete circumference.

[0052] The opening arc length refers to the straight-line length of the C-shaped fixed groove 21 after its opening end is unfolded along the circumference, which can be achieved by adjusting the central angle of the C-shaped groove. The complete circumference refers to the circumference of a complete circular closed structure with the same inner diameter as the C-shaped groove. The ratio between the opening arc length and the complete circumference directly affects the elastic deformation capability of the C-shaped groove and the area of ​​the pipeline it covers.

[0053] Specifically, when the opening arc length of the C-groove is set to one-third of the complete circumference, the groove walls on both sides of the opening end can generate a moderate elastic expansion when the pipeline is inserted, allowing the pipeline to smoothly enter the groove. After insertion, the wrapping area formed by the elastic reset of the groove walls can both limit the radial displacement of the pipeline and prevent the pipeline from detaching due to vibration caused by an excessively large opening. This ratio, by balancing the deformation of the groove body and the wrapping area, solves the installation difficulties and fixation failures caused by improper opening dimensions in traditional solutions.

[0054] Through the above technical solution, this application realizes the rapid installation and reliable fixation of pipelines in the fixing groove 21, eliminating the cumbersome operation and aging failure problems of traditional binding methods. At the same time, by optimizing the opening size, it avoids the situation of pipelines falling off due to vibration or installation difficulties, and improves the service life and safety of pipeline fixing device 100.

[0055] In one embodiment, the pipeline fixing device 100 is a one-piece molded component.

[0056] In this context, a one-piece molded part refers to a component whose complete structure is directly formed through a single mold or molding process, specifically injection molding, die casting, or stamping. This feature eliminates the splicing or assembly interface between the clamping part 1 and the fixing part 2, thus eliminating potential failure points of connecting parts in a split structure.

[0057] Specifically, during the manufacturing process, the clamping part 1 and the fixing part 2 are formed into an integral structure by continuous material molding, and the geometry of the clamping groove 11 and the fixing groove 21 is formed simultaneously during the molding stage. Since no subsequent assembly is required, the fit tolerance between the parts is controlled within a single molding process, avoiding the cumulative error caused by the assembly of multiple parts in a split structure.

[0058] Through the above technical solution, this application solves the problem of complex assembly process for split structures, reduces the risk of pipeline detachment due to loose connectors, and avoids the potential for single-point failure caused by aging cable ties. Installation is completed simply by inserting the pipeline directly into the fixing groove 21; maintenance does not require disassembling connectors or cutting cable ties, thus improving operational efficiency.

[0059] This application further proposes multiple fixing slots 21 with the same or different dimensions.

[0060] The different dimensions of the fixing grooves 21 refer to variations in width or depth, which can be achieved by adjusting the opening width or bottom curvature of the groove. This feature allows the same device to accommodate pipelines of different diameters, avoiding difficulties in pipe insertion or fixing failure due to uniform size. Conversely, the identical dimensions of the fixing grooves 21 mean that all fixing grooves 21 have uniform specifications, which can be achieved through standardized groove structures. This feature is suitable for batch fixing of pipelines of the same specification, reducing the complexity of identifying groove positions during assembly.

[0061] Specifically, when it is necessary to fix pipelines of different diameters, fixing slots 21 of different sizes can be selected. For example, a wider slot is used to accommodate thicker pipelines, and a narrower slot is used to fix thinner pipelines. During this process, the pipeline is directly inserted into the corresponding size slot through the slot opening, without the need for auxiliary tools such as cable ties. When it is necessary to fix the same pipelines in batches, fixing slots 21 of the same size can achieve rapid positioning and avoid assembly errors caused by differences in slot size.

[0062] In some specific embodiments, the width of the fixing groove 21 can be, for example, 5 mm, 8 mm or 12 mm, to accommodate different wire harness diameters; the depth of the fixing groove 21 can be, for example, 1.2 times the width of the groove opening, to ensure that the pipeline is not easily dislodged after being inserted.

[0063] Through the above technical solution, this application solves the problem of poor pipeline compatibility caused by the single size of the fixing groove 21 in the prior art, realizes the reliable fixing of pipelines of different specifications on the same device, and simplifies the installation steps and reduces the maintenance difficulty.

[0064] In one embodiment, the plurality of fixing slots 21 include at least two different widths of slots.

[0065] The fixed groove 21 refers to a groove structure used to accommodate and constrain pipeline displacement. Specifically, it can be formed into an open C-shaped groove using injection molding or stamping processes. The opening direction is perpendicular to the pipeline laying path to prevent pipeline detachment. Different widths of the groove refer to differences in the lateral dimensions at the opening of the groove. Specifically, this can be achieved by adjusting the mold parameters to form grooves with widths of 5mm, 8mm, and 12mm. The width differences allow the grooves to accommodate pipelines with diameters of 4mm, 7mm, and 10mm, respectively.

[0066] Specifically, during pipeline installation, smaller diameter pipelines are clamped into narrower trenches, with the trench sidewalls making surface contact with the pipeline surface to limit radial displacement. Larger diameter pipelines are embedded in trenches of matching width, with the curved edges at the trench openings preventing shear stress on the pipeline sheath. Trenches of different widths are arranged alternately along the extension direction of clamping part 1, allowing the same device to simultaneously secure multiple specifications of pipelines, such as power cables, signal lines, and hydraulic pipes, enabling parallel installation without the need for auxiliary tools such as cable ties.

[0067] Through the above technical solution, this application achieves reliable fixing of pipelines of different diameters in a single device. During installation, the pipeline can be directly snapped into the corresponding width of the groove without repeatedly adjusting the tightness of the cable ties. During maintenance, the replacement or repair of a specific pipeline only requires removing it from the corresponding groove, without affecting the fixing status of pipelines in other grooves, significantly improving maintenance efficiency.

[0068] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
