Description

Technical Field

[0001] This application relates to the field of pipe fixing, and more particularly to a pipe fixing device for a vehicle. Background Technology

[0002] In related technologies, as hybrid vehicles develop towards higher power, longer range, and higher integration, mid-to-large passenger vehicles have become a key focus of technological breakthroughs due to their strong space carrying capacity. These types of vehicles require the installation of various pipelines, including fuel systems, high-voltage battery thermal management circuits, motor and electronic control cooling systems, air conditioning pipelines, brake pipelines, and high-voltage wiring harnesses. These pipelines are all concentrated in the middle of the chassis, that is, around the battery pack and under the passenger compartment.

[0003] Currently, for multiple parallel or intersecting pipelines, multiple independent pipe clamps are typically used for individual fixing. However, this fixing method is relatively cumbersome to install, occupies a large amount of space, and makes it difficult to ensure the installation consistency between pipelines and between pipelines and supports. In addition, different pipelines have different vibration reduction requirements due to differences in the media they transport, operating pressures, and importance. Some need to suppress high-frequency noise, while others need to isolate low-frequency, large-amplitude vibrations. Existing fixing devices cannot achieve this targeted, differentiated vibration reduction. Summary of the Invention

[0019] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0020] The following is for reference. Figures 1-3 The present application describes a pipe fixing device 10 for a vehicle, which includes a first housing 11 and a second housing 12.

[0021] The first housing 11 has a plurality of first mounting holes 111 extending through it along its thickness direction. The plurality of first mounting holes 111 are spaced apart along the length direction of the first housing 11. A fastener 13 connected to the first housing 11 is provided between two adjacent first mounting holes 111. At least a portion of the fastener 13 extends toward the two adjacent first mounting holes 111. The first housing 11 also has a first mounting groove 112 recessed along its width direction. The second housing 12 is connected to the first housing 11. The second housing 12 has a second mounting groove 121 recessed along its width direction. The second mounting groove 121 and the first mounting groove 112 are correspondingly provided along their width directions to define a second mounting hole 122 extending through it along its thickness direction. At least one vibration damping member 14 is provided on the inner wall of the second mounting hole 122.

[0022] Currently, for multiple parallel or intersecting pipelines, multiple independent pipe clamps are typically used for individual fixing. However, this fixing method is relatively cumbersome to install, occupies a large amount of space, and makes it difficult to ensure the installation consistency between pipelines and between pipelines and supports. In addition, different pipelines have different vibration reduction requirements due to differences in the media they transport, operating pressures, and importance. Some need to suppress high-frequency noise, while others need to isolate low-frequency, large-amplitude vibrations. Existing fixing devices cannot achieve this targeted, differentiated vibration reduction.

[0023] In response, this application proposes a pipe fixing device 10, which can integrate and fix multiple pipes and achieve coordinated control of vibrations at different frequencies.

[0024] Specifically, the pipeline fixing device 10 includes a first housing 11 and a second housing 12, which cooperate to fix and dampen different types of pipelines. The first housing 11 may have a layer formed along its thickness direction (e.g., ...). Figure 1The first mounting hole 111 (shown in the X direction) is provided through the first mounting hole 111. The number of first mounting holes 111 can be set to multiple, and the multiple first mounting holes 111 can be along the length direction of the first housing 11 (e.g., ...). Figure 1 The first mounting holes 111 are arranged at intervals in the Y direction shown in the diagram. Optionally, the interval between each first mounting hole 111 is the same. The first mounting holes 111 can be used to accommodate pipelines that vibrate at low frequencies, such as hydraulic pipes and fuel pipes. These pipelines vibrate at low frequencies and relatively large amplitudes during operation.

[0025] A fixing member 13 can also be provided between two adjacent first mounting holes 111. The fixing member 13 can be connected to the first housing 11. Optionally, the fixing member 13 and the first housing 11 can be detachably connected by screws or bolts, or the fixing member 13 and the first housing 11 can be detachably connected by snap-fit ​​or plug-in, or the fixing member 13 and the first housing 11 can be integrally injection molded. At least a part of the structure of the fixing member 13 can extend toward the two adjacent first mounting holes 111. It is understood that the fixing members 13 on both sides of each first mounting hole 111 can clamp, fix and limit the pipeline contained in the first mounting hole 111 from both sides of the pipeline, effectively preventing the pipeline from shifting or shaking during vibration, avoiding collision and wear between the pipeline and the inner wall of the mounting hole, and extending the service life of the pipeline.

[0026] In some embodiments, the first housing 11 may be made of a high-damping, medium-stiffness elastic material, such as high-damping silicone rubber, polyurethane, etc. Such materials have good low-frequency vibration absorption and dissipation capabilities, which can effectively buffer the low-frequency vibration transmitted by the pipeline. At the same time, the medium stiffness can ensure the structural strength of the housing itself and avoid fixation failure due to insufficient stiffness.

[0027] Furthermore, the second housing 12 and the first housing 11 are assembled in a detachable or fixed manner, and the first housing 11 may be formed with a shape along its width direction (e.g., Figure 1 The first mounting groove 112 (shown in the Z direction) is recessed inwards. The second housing 12 has a second mounting groove 121 recessed inwards along its width direction. The second mounting groove 121 is correspondingly provided with the first mounting groove 112 along its width direction, thereby defining a second mounting hole 122 that extends through along its thickness direction. The second mounting hole 122 can be used to accommodate pipelines with high noise control requirements. Such pipelines are prone to high-frequency vibration when working, which can cause noise and affect the driving comfort of the vehicle.

[0028] The inner wall of the second mounting hole 122 can be provided with at least one vibration damping element 14. The vibration damping element 14 can be made of rubber, which has good elasticity and vibration damping and noise reduction performance. By directly contacting the vibration damping element 14 with the pipe surface, the high-frequency vibration and noise emitted by the pipe can be effectively isolated and absorbed. At the same time, the second housing 12 can be made of a low-stiffness, variable damping material, or the second housing 12 can be constructed with a non-linear geometric structure such as hollow or corrugated, thereby further reducing the natural frequency of the second housing 12, avoiding its high-frequency vibration frequency from that of the pipe, reducing the occurrence of resonance, and further improving the high-frequency vibration damping and noise reduction effect.

[0029] In a specific embodiment, the area where the first mounting hole 111 is located can serve as a low-frequency vibration reduction zone. This area mainly absorbs and dissipates the low-frequency, large-amplitude vibration energy emitted by hydraulic pipes, fuel pipes, and other pipelines, preventing the overall structure from shaking significantly. The area where the second mounting hole 122 is located can serve as a high-frequency vibration reduction zone. This area utilizes its low natural frequency and the viscoelasticity of the material to effectively isolate and absorb high-frequency vibrations and noise, reduce the transmission of noise into the passenger compartment, and improve the driving comfort of the vehicle.

[0030] In short, the pipe fixing device 10 of this application embodiment has a first housing 11 and a second housing 12. The first housing 11 forms a first mounting hole 111. A fixing member 13 is provided between two adjacent first mounting holes 111. At least a portion of the fixing member 13 can extend toward the first mounting hole 111 to fix and dampen the low-frequency, large-amplitude pipe in the first mounting hole 111. The first housing 11 and the second housing 12 respectively form a corresponding first mounting groove 112 and a second mounting groove 121. The first mounting groove 112 and the second mounting groove 121 define a second mounting hole 122. At least one damping member 14 is provided on the inner wall of the second mounting hole 122, thereby effectively isolating and absorbing the high-frequency vibration and noise emitted by the pipe, thereby ensuring that the pipe fixing device 10 can integrate and fix multiple pipes and achieve coordinated control of vibrations of different frequencies.

[0031] like Figure 1As shown, in some embodiments of this application, the fixing member 13 may include a main body 131 and a fixing part 132. The main body 131 extends along the width direction, and one end of the main body 131 along the width direction is fixedly connected to or integrally formed with the first housing 11, thereby connecting the fixing member 13 to the first housing 11. The fixing part 132 may be disposed on both sides of the main body 131 along the length direction, and the fixing part 132 may be connected to the other end of the main body 131 along the width direction. The fixing part 132 may extend toward the adjacent first mounting hole 111. After the pipeline is assembled in place, the free end of the fixing part 132 can abut against the surface of the pipeline, thereby effectively preventing the pipeline from shifting or shaking during vibration, avoiding collision and wear between the pipeline and the inner wall of the mounting hole, and extending the service life of the pipeline.

[0032] like Figure 3 As shown in some embodiments of this application, a guide surface 1321 can be formed on the surface of the fixing part 132 facing away from the first mounting hole 111. The guide surface 1321 can extend toward the first mounting hole 111. It should be noted that when the installation pipe is installed into the first mounting hole 111, the pipe can first contact the guide surface 1321 and press the fixing part 132, causing the fixing part 132 to undergo elastic deformation, thereby widening the gap between two adjacent fixing parts 132, so as to facilitate the installation of the pipe into the first mounting hole 111. In this process, the guide surface 1321 can play a guiding role, reduce the assembly resistance of the pipe, improve the assembly efficiency of the pipe, and facilitate the installation of the pipe.

[0033] like Figure 1 As shown, in some embodiments of this application, the plurality of first mounting holes 111 may include first sub-mounting holes 1111 and second sub-mounting holes 1112. The inner diameter of the first sub-mounting hole 1111 is smaller than the inner diameter of the second sub-mounting hole 1112. By setting first sub-mounting holes 1111 and second sub-mounting holes 1112 with different inner diameter specifications, the first housing 11 can be adapted to and install various pipelines with different outer diameters, meet the diverse assembly requirements of pipelines, and improve the adaptability and versatility of the first mounting holes 111 to pipelines of different specifications.

[0034] like Figure 1As shown, in some embodiments of this application, the number of first mounting slots 112 can be set to multiple, and the multiple first mounting slots 112 can be spaced apart along the length direction. The spacing between two adjacent first mounting slots 112 can be flexibly adjusted according to the actual pipeline installation density and pipeline spacing requirements. The number of second mounting slots 121 can be set to multiple, and the number of second mounting slots 121 is consistent with the number of first mounting slots 112. The multiple second mounting slots 121 can be set one-to-one with the multiple first mounting slots 112, thereby defining multiple second mounting holes 122. That is, after each first mounting slot 112 is connected to the corresponding second mounting slot 121, a second mounting hole 122 for pipeline to pass through is defined together, and multiple pipelines are fixed at the same time. The structure is compact, the number of installation points and parts is reduced, the installation efficiency and system reliability are improved, and it is convenient to realize standardized and modular design.

[0035] Furthermore, the plurality of second mounting holes 122 may include a third sub-mounting hole 1221 and a fourth sub-mounting hole 1222. The inner wall of the third sub-mounting hole 1221 may be provided with a plurality of vibration damping elements 14, which may be arranged at intervals along the circumference of the third sub-mounting hole 1221 to ensure that the vibration damping elements 14 exert uniform force on the pipeline. The shape of the fourth sub-mounting hole 1222 is different from that of the third sub-mounting hole 1221. In some embodiments, the third sub-mounting hole 1221 may be a circular hole, and the fourth sub-mounting hole 1222 may be set as a square, elliptical or other irregular structure to adapt to pipelines with different cross-sectional shapes. The inner wall of the fourth sub-mounting hole 1222 is provided with at least one vibration damping element 14. The vibration damping element 14 may be flexibly set in the installation position according to the vibration characteristics of the pipeline and the installation space. The vibration damping element 14 is preferably set in the area where the vibration amplitude of the pipeline is the largest. The third sub-mounting hole 1221 and the fourth sub-mounting hole 1222 can be used to install different types of high-frequency vibration pipelines. The vibration damping component 14 has elasticity and vibration reduction and noise reduction performance. By directly contacting the vibration damping component 14 with the pipeline surface, the high-frequency vibration and noise emitted by the pipeline can be effectively isolated and absorbed.

[0036] like Figure 3 As shown, in some embodiments of this application, there are multiple third sub-mounting holes 1221, and at least one pair of adjacent third sub-mounting holes 1221 have different inner diameters. By setting third sub-mounting holes 1221 with different inner diameter specifications, the third sub-mounting holes 1221 can be adapted to and install various pipelines with different outer diameters, meet the diverse assembly requirements of pipelines, and improve the adaptability and versatility of the third sub-mounting holes 1221 to pipelines of different specifications.

[0037] like Figure 1 and Figure 3As shown, in some embodiments of this application, a first positioning part 113 is provided on the side of the first housing 11 facing the second housing 12, and a second positioning part 123 is provided on the second housing 12. The second positioning part 123 can cooperate with the first positioning part 113. Optionally, the first positioning part 113 can be constructed as one of a positioning post and a positioning hole, and the second positioning part 123 can be constructed as the other of a positioning post and a positioning hole. By cooperating with the positioning hole, the positioning post is received in the positioning hole, thereby positioning the first housing 11 and the second housing 12, which helps to assemble the first housing 11 and the second housing 12.

[0038] like Figure 1 and Figure 3 As shown, in some embodiments of this application, a first mounting portion 114 is provided on the side of the first housing 11 facing the second housing 12, and a second mounting portion 124 is provided on the second housing 12. The second mounting portion 124 can be fixedly connected to the first mounting portion 114. Optionally, the first mounting portion 114 can be constructed as one of a mounting protrusion and a mounting groove, and the second mounting portion 124 can be constructed as the other of a mounting protrusion and a mounting groove. By engaging the mounting protrusion with the mounting groove, the mounting protrusion is received within the mounting groove, and the outer surface of the mounting protrusion abuts against the inner surface of the mounting groove to restrict the movement of the mounting protrusion, thereby allowing the second housing 12 to be mounted on the first housing 11. In some embodiments, the number of first mounting portions 114 can be set to multiple, and the number of second mounting portions 124 can also be set to multiple, and multiple second mounting portions 124 can be correspondingly arranged and connected to multiple first mounting portions 114, thereby improving the connection strength between the first housing 11 and the second housing 12.

[0039] like Figure 1 and Figure 3As shown, in some embodiments of this application, a fixing hole 115 may be formed inside the first housing 11. The fixing hole 115 can be arranged through the length direction, and the inner wall of the fixing hole 115 can be formed with a stepped surface. The pipeline fixing device 10 also includes a mounting bolt 15, which can be inserted through the fixing hole 115. One end of the mounting bolt 15 can abut against the stepped surface, and the other end of the mounting bolt 15 can be connected to the vehicle body, thereby fixing the first housing 11 to the vehicle body. In actual assembly, the low-frequency vibration pipeline is first fixed in the first mounting hole 111 to ensure that the position of the low-frequency vibration pipeline is accurate and fixed. After ensuring reliability, the shank of the mounting bolt 15 is passed through the fixing hole 115 from one side of the first housing 11, so that the bolt head is tightly abutted against the stepped surface of the inner wall of the fixing hole 115. Then, the other end of the mounting bolt 15 is aligned with the body parts and tightened to complete the fixing of the first housing 11 to the body. Then, the high-frequency vibration pipeline is installed in the first mounting groove 112, and the second housing 12 is fixed to the first housing 11 to fix the high-frequency vibration pipeline. Through the cooperation of the first mounting groove 112 and the second mounting groove 121, the high-frequency vibration pipeline is firmly clamped and fixed, thereby completing the assembly of the entire pipeline fixing device 10.

[0040] like Figures 1 to 3 As shown, in some embodiments of this application, the first housing 11 has first weight-reducing grooves 116 extending inward on both sides along its thickness direction. The shape of the first weight-reducing grooves 116 can be flexibly designed according to the external structure and stress conditions of the first housing 11, for example, it can be set as a rectangular, trapezoidal, or arc-shaped groove. The depth and width of the first weight-reducing grooves 116 need to be determined by structural strength calculations to ensure that while reducing weight, the first housing 11 can meet the stress requirements for pipe fixing and vehicle body connection. Correspondingly, the second housing 12 also has first weight-reducing grooves 116 extending inward on both sides along its thickness direction. The second weight-reducing groove 125 is adapted to the structure of the first weight-reducing groove 116. The second weight-reducing groove 125 also extends toward the interior of the second housing 12. Its position corresponds to the position of the first weight-reducing groove 116, so that after the second housing 12 is connected to the first housing 11, the first weight-reducing groove 116 and the second weight-reducing groove 125 can form a symmetrical weight-reducing structure, further optimizing the overall weight-reducing effect. By setting the first weight-reducing groove 116 and the second weight-reducing groove 125, the overall weight of the pipeline fixing device 10 can be effectively reduced, the vehicle body load can be reduced, and material costs can be saved.
