[0026] Figure 1 1 is a three-dimensional schematic diagram of a pipeline fixing device 10 according to an embodiment of the present application. The pipeline fixing device 10 mainly includes a first clamping member 110, a second clamping member 120, a first connecting portion 210 connected to the first clamping member 110, and a second connecting portion 220 connected to the second clamping member 120. The first clamping member 110 and the second clamping member 120 can be configured to respectively connect to the first pipeline 21 and the second pipeline 22 (see Figure 4 or Figure 5) are detachably connected. The first pipeline 21 and the second pipeline 22 may be two pipelines in the vehicle cooling pipeline system, or two wiring harnesses in the vehicle wiring harness system, etc. The first connecting part 210 may include a hollow sleeve 211, and the second connecting part 220 may include a column 221, the outer diameter of the column 221 matches the inner diameter of the sleeve 211, for example, slightly smaller than the inner diameter of the sleeve 211. The column 221 is configured to be rotatably inserted into the sleeve 211 and movable relative to the sleeve 211 along the axis of the sleeve 211, so that the first connecting part 210 is rotatable and axially movable relative to the second connecting part 220, thereby driving the first clamping member 110 to be rotatable and axially movable relative to the second connecting part 220, thereby realizing the rotation and extension of the pipeline fixing device 10. In addition, the first clamping member 110 and the second clamping member 120 are respectively movably connected to the first connecting portion 210 and the second connecting portion 220 in a manner that they can rotate relative to each other around the axis of the sleeve, so that the rotation of the clamping member (the first clamping member 110 or the second clamping member 120) around the axis of the sleeve is decoupled from the rotation of the corresponding connecting portion (the first connecting portion 210 or the second connecting portion 220) around the axis of the sleeve. Specifically, for example, when the first connecting portion 210 rotates relative to the second connecting portion 220, the first clamping member 110 can rotate in the opposite direction instead of rotating with the first connecting portion 210 to offset the rotation of the first connecting portion 210, thereby avoiding rotational dislocation or torsional entanglement of the pipeline connected to the first clamping member 110. The rotational decoupling design of the second clamping member 120 is similar.

[0027] In addition, the pipeline fixing device 10 may also include only one clamping member connected to one of the first connection part 210 and the second connection part 220, while the other of the first connection part 210 and the second connection part 220 is connected to a preset position in the vehicle, thereby realizing the constraint of the pipeline relative to the preset position in the vehicle.

[0028] According to the rotatable and retractable pipeline fixing device 10 of the present application, flexible fixing of the pipeline is achieved. During the operation of the vehicle, when the motion source causes the pipeline to twist or shift, the pipeline fixing device 10 can effectively control the motion trajectory and motion amplitude of the pipeline, absorb a certain amount of pipeline motion energy, prevent the pipeline from being greatly offset and causing damage to the overall layout of the pipeline system, and prevent pipelines from being damaged by mutual collision and friction between pipelines or between pipelines and other structures, thereby ensuring the reliability of the pipeline system. In addition, due to the rotatable and retractable structure of the pipeline fixing device 10 itself, after the motion source stops moving, the pipeline fixing device 10 can drive the pipeline to return to its original layout position under the drive of the interaction force with the pipeline, thereby ensuring the optimal layout state of the pipeline system.

[0029] The following will introduce further specific implementation or refinement and improvement process of the pipeline fixing device 10 through exemplary description, so as to further improve its working efficiency, reliability or for other improvement considerations.

[0030] like Figure 1 As shown, the first connection portion 210 may further include a first base 212, which is disposed at the end of the sleeve 211 facing away from the second connection portion 220 (ie, the end farther away from the second connection portion 220, i.e. Figure 1 The first clamping member 110 is movably connected to the side of the first base 212 facing away from the sleeve 211, that is, the first clamping member 110 and the first base 212 can rotate relative to each other around the axial direction (i.e., the axial direction of the sleeve). Optionally, the connection between the first clamping member 110 and the first base 212 along the axial direction can be relatively fixed or relatively movable. The second connecting portion 220 can include a second base 222, which is arranged at the end of the column 221 facing away from the first connecting portion 210 (i.e., the upper end in the figure) and extends perpendicular to the axis of the column 221. The second clamping member 120 is movably connected to the side of the second base 222 facing away from the column 221, that is, the second clamping member 120 and the second base 222 can rotate relative to each other around the axial direction. Optionally, the connection between the second clamping member 120 and the second base 222 along the axial direction can be relatively fixed or relatively movable. The provision of the first base 212 and the second base 222 can facilitate the connection between the sleeve 211 and the first clamp 110 and between the column 221 and the second clamp 120, respectively, and play the role of balancing weight and assisting orientation. For example, the installation direction of the first clamp 110 or the second clamp 120 can be quickly determined by means of the geometric features of the first base 212 or the second base 222 (for example, the rectangle shown in the figure). It should be understood that in other embodiments, the first base 212 and the second base 222 can be configured in the same or different forms, and the contours of the first base 212 and the second base 222 can exceed the circular contour of the sleeve 211 or the column 221 or match the circular contour of the sleeve 211 or the column 221, or the first base 212 and the second base 222 can be not provided to simplify the structure of the pipeline fixing device 10 (wherein the sleeve 211 can be configured in the form of a bottom seal for directly installing the first clamp 110). In addition, the first clamping member 110 and the second clamping member 120 may also be configured in the same or different forms and may have the same Figure 1 The opening arcs shown in the figure have different geometries.

[0031] In a specific embodiment, the sleeve 211 may be configured with a slide groove 2111 extending spirally on the wall surface of the sleeve 211 around the axis of the sleeve 211. Specifically, the slide groove 2111 may be configured to be recessed from the inner wall of the sleeve 211 toward the outside of the sleeve 211. The recessed distance may be less than the wall thickness of the sleeve 211, so that the slide groove 2111 is only visible inside the sleeve 211, or the recessed distance may be as Figure 1 The thickness shown in the figure is equal to the wall thickness of the sleeve 211, that is, the slide groove 2111 penetrates the wall of the sleeve 211 in the radial direction, so as to facilitate observation and assembly operation. The second connecting portion 220 includes a protrusion 2211 protruding radially outward from the column 221, and the protrusion 2211 is configured to be snapped into the slide groove 2111 and slide along the slide groove 2111 to drive the column 221 to rotate relative to the sleeve 211 and move axially while rotating. In the specific manufacturing and assembly process, the sleeve 211 can be first processed into two parts separated along the longitudinal section, and after the protrusion 2211 is snapped into the slide groove 2111, the two parts are combined together.

[0032] In a preferred embodiment, reference Figure 2 The sleeve 211 may include two radially oppositely arranged slide grooves 2111, that is, the two slide grooves 2111 are symmetrical about the axis center of the sleeve 211, and the second connecting part 220 may include two radially oppositely arranged protrusions 2211, and the two protrusions 2211 are respectively clamped in the two slide grooves 2111 to improve the assembly positioning accuracy and relative movement smoothness of the first connecting part 210 and the second connecting part 220.

[0033] like Figure 2 and Figure 3 As shown, a return spring 300 may be provided between the end of the column 221 facing the first connection part 210 and the first connection part 210 (specifically, the first base 212 at the bottom end of the sleeve 211 or the bottom of the sleeve 211). The return spring 300 is configured to drive the column 221 to return to the set assembly position when the column 221 deviates from the set assembly position with the sleeve 211 and moves axially. For example, in the original assembly state, the return spring 300 may be configured to be compressed between the column 221 and the first connection part 210. For example, the natural length of the return spring 300 when it is not under force may be set to be not less than the axial length of the slide groove 2111, so that the return spring 300 is always in a compressed state after assembly. Figure 3As shown, when the two pipelines connected to the pipeline fixing device 10 are relatively close to each other under the action of external force, the force exerted by the return spring 300 on the columns 221 and the first base 212 at both ends is less than the force exerted by the two pipelines on the pipeline fixing device 10, the pipeline fixing device 10 contracts, and the return spring 300 is compressed. After the external force is removed, the spring force is greater than the force exerted by the two pipelines on the pipeline fixing device 10, thereby pushing the column 221 back to the set assembly position, so that the pipeline meets the initially set layout clearance requirement. In actual operation, the length of the sleeve 211 and the column 221, the axial length of the slide groove 2111, and the natural length of the return spring 300 can be specifically set according to the actual layout requirements between the pipelines. Figure 2 or Figure 3 In the illustrated embodiment, one end of the return spring 300 facing the first base 212 is fixedly connected to the first base 212, and the end facing the column 221 is not connected to the column 221, but in an optional embodiment, the two ends of the return spring 300 may be respectively fixedly connected or not fixedly connected to the first connecting portion 210 (for example, specifically the first base 212) or the column 221.

[0034] In another embodiment, the return spring 300 can also be arranged between the column 221 and the first connection part 210 in a stretched state that does not exceed its stretching limit during at least part of the telescopic stroke of the pipeline fixing device 10, for example, the return spring 300 is always in a stretched state, or the return spring 300 is in a compressed state in the set assembly position and changes to a stretched state as the pipeline fixing device 10 gradually stretches. In this case, the two ends of the return spring 300 can be respectively fixed to the first connection part 210 (for example, specifically the first base 212) and the column 221, so that the set assembly position between the two pipelines is maintained by the tension of the return spring 300, or the two relatively distant pipelines are returned to the set assembly position by the tension of the return spring 300. In this case, the natural length of the return spring 300 can be less than the axial extension distance of the slide groove 2111, which can be set according to actual conditions.

[0035] In a preferred embodiment, a contact block 310 may be provided at one end of the return spring 300 facing the column 221, and the contact block 310 abuts against or contacts the end of the column 221 to provide surface contact with the column 221, reduce scratches on the column 221 by the return spring 300, and improve the uniformity and stability of the force.

[0036] In addition, in addition to the above-mentioned rotational telescopic extension of the pipeline fixing device realized by the slide groove form, other construction methods can also be used to realize its rotation and telescopic functions. For example, without setting the slide groove 2111 and the protrusion 2211, a torsion telescopic spring can be used instead of the return spring 300, and the two ends of the torsion telescopic spring are respectively fixedly connected to the sleeve 211 and the column 221. The axial relative displacement between the sleeve 211 and the column 221 is realized by the axial extension and contraction of the torsion telescopic spring, and the relative circumferential rotation between the sleeve 211 and the column 221 is realized by the torsion of the torsion telescopic spring.

[0037] Figure 4 It is a schematic diagram of a pipeline system according to an embodiment of the present application, which is specifically a cooling pipeline system of a vehicle, including a first pipeline 21 and a second pipeline 22 (in this embodiment, they are respectively a first cooling pipeline and a second cooling pipeline), and the two pipelines are flexibly fixed via a first clamp 110 and a second clamp 120 of a pipeline fixing device 10. Figure 5 It is a schematic diagram of a pipeline system according to another embodiment of the present application, which is a vehicle wiring harness system, including a first pipeline 21 and a second pipeline 22 (in this embodiment, the first wiring harness and the second wiring harness, respectively), and the two pipelines are flexibly fixed via the first clamp 110 and the second clamp 120 of the aforementioned pipeline fixing device 10.

[0038] Under this arrangement, according to the pipeline system of the present application, the relative torsion and displacement between pipelines are effectively controlled by setting the pipeline fixing device 10, thereby avoiding relative collision or wear between pipelines, and being able to effectively control the redundant space between pipelines, thereby improving the integration effect of the pipeline system.

[0039] The above examples mainly illustrate the pipeline fixture, pipeline system and vehicle of the present application. Although only some of the embodiments of the present application are described, it should be understood by those skilled in the art that the present application can be implemented in many other forms without departing from its subject matter and scope. Therefore, the examples and embodiments shown are regarded as illustrative rather than restrictive, and the present application may cover various modifications and substitutions without departing from the spirit and scope of the technical solution of the present application.
