Description

Technical Field

[0001] This utility model relates to the field of automobile design and manufacturing, and in particular to a pipeline installation structure and an automobile. Background Technology

[0002] The corner module driven by the hub motor is an assembly that integrates drive, braking, suspension and steering into one module. The steering drive of the left and right wheels is realized by the steering motor in the independent corner module, so that each wheel can rotate independently, thereby reducing a large number of mechanical transmission parts and optimizing the overall vehicle layout space.

[0003] The hoses and wiring harnesses in corner modules (such as cooling pipes and high-voltage wiring harnesses) generally require a fixed pipeline mounting structure to be partially fixed to the vehicle structure. The axial, radial, and circumferential directions of the axial, radial, and circumferential connections between the pipelines and the mounting structure are completely fixed relative to the vehicle structure. However, the middle section of the pipeline located between the corner module and the mounting structure, completely constrained by the mounting structure, will experience significant torsional deformation relative to the vehicle structure during wheel steering. This results in substantial torsional shear stress on the pipeline, and repeated torsion over a long period can easily lead to fatigue damage, severely reducing its service life.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

At least a portion of the rotating component is disposed within the first through hole of the fixing component and is axially limited by the fixing component. The rotating component has a second through hole for fixing the pipeline and can rotate along the inner circumferential wall of the first through hole. Thus, the pipeline configured on the corner module is partially fixed within the second through hole of the rotating component, while the fixing component is fixed to the vehicle structure.

The description of "multiple" generally means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can be a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0042] It should be noted that the axial, radial and circumferential directions in the embodiments of this utility model are all defined based on the first through hole 101.

[0043] As mentioned above, the general concept of this utility model embodiment is to provide a pipeline installation structure 100. By optimizing the design of the pipeline installation structure 100, the pipeline 30 is not constrained by the pipeline installation structure 100 in the circumferential direction during the torsion process, thereby reducing the torsional shear stress of the pipeline 30 during the torsion process. This satisfies the turning requirements of the corner module while improving the service life of the pipeline 30 after long-term torsion.

[0044] Based on the above concept, and referring to Figures 1-6 As shown, this utility model embodiment provides a pipeline installation structure 10, including a fixing member 100 and a rotating member 200; the fixing member 100 has a first through hole 101 and is used to fix and connect a vehicle structure 20; the rotating member 200 is at least partially disposed in the first through hole 101 and is fixed relative to the fixing member 100 along the axial direction of the first through hole 101, and the rotating member 200 has a second through hole 201 for fixing a pipeline 30; wherein, the rotating member 200 is configured to be able to rotate along the inner peripheral wall of the first through hole 101 under the torsional drive of the pipeline 30.

[0045] It is understood that the fixing member 100 in this embodiment can install and fix the pipeline installation structure 10 as a whole onto the vehicle structure 20. The fixing member 100 has a first through hole 101. The rotating member 200 is cylindrical. The rotating member 200 is at least partially disposed in the first through hole 101 and is fixed axially relative to the fixing member 100. It can rotate along the inner peripheral wall of the first through hole 101. The second through hole 201 formed by the rotating member 200 is adapted to the outer contour of the pipeline 30 and is used to fix the pipeline 30 to fix the pipeline 30 in the rotating member 200. This allows the rotating member 200 to rotate in the first through hole 101 during the torsion process of the pipeline 30, thereby reducing the torsional shear stress during the torsion process of the pipeline 30.

[0046] The pipeline installation structure 10 provided in this embodiment has a simple structure, few components, and is easy to disassemble and assemble, which helps to reduce the overall vehicle production cost and subsequent maintenance cost. Compared with the traditional fixed pipeline installation structure, it can not only fix the pipeline axially, but also increase the length of the part of the pipeline 30 that participates in axial torsion, reduce its torsional shear stress, and improve the service life of the pipeline 30. This makes the pipeline installation structure 10 particularly suitable for use in integrated steering angle module architecture vehicles to meet the 90° steering motion requirements of the angle module.

[0047] It should be understood that the pipeline 30 in the embodiments of this application can be a flexible hose responsible for transporting the cooling medium, or a high-voltage wiring harness responsible for electrical connections.

[0048] Since the pipeline 20 is fixedly connected inside the rotating component 200, to prevent the rotating component 200 from being dislodged from the first through hole 101 by the torsion of the pipeline 20, refer to Figures 1-3As shown, in some embodiments, the fixing member 100 includes a fixing bushing 110 and a fixing snap ring 120; the fixing bushing 110 has a first through hole 101, and one end of the fixing bushing 110 has a through groove 102, which radially passes through the first through hole 101; the corresponding end of the rotating member 200 has a mating blind groove 202, which radially corresponds to the through groove 102; the fixing snap ring 120 passes radially through the through groove 102 and is disposed in the mating blind groove 202 to restrict the axial degree of freedom of the rotating member 200.

[0049] In this embodiment, the fixed bushing 110 has a first through hole 101. A through groove 102 is provided at one end of the fixed bushing 110 along the axial direction. The through groove 102 extends circumferentially along the fixed bushing 110 and passes through the first through hole 101 radially. A matching blind groove 202 is provided on the outer wall of the corresponding end of the rotating member 200. The matching blind groove 202 is radially opposite to the through groove 102. The fixed snap ring 120 passes radially through the through groove 102 and is disposed in the matching blind groove 202. This prevents the rotating member 200 from moving axially after being installed in the first through hole 101, so as to avoid being driven by the pipeline 30 and falling out of the fixed member 200. Furthermore, the matching blind groove 202 is arranged around the outer wall of the rotating member 200, so that the fixed snap ring 120 can move relative to the matching blind groove 202 during the rotation of the rotating member 200, thus avoiding affecting the rotation of the rotating member 200 along the inner circumferential wall of the first through hole 101.

[0050] Continue to refer to Figure 2 and Figure 3 In some embodiments, the fixed bushing 110 includes a bushing body 111 and a fixing clip 112; the bushing body 111 includes a first flange section 1111, a bushing intermediate section 1112 and a second flange section 1113 connected sequentially along the axial direction, the first flange section 1111, the bushing intermediate section 1112 and the second flange section 1113 together form a first through hole 101; a through groove 102 is provided on the second flange section 1113; the first flange section 1111 is used to abut against the rotating member 200 along the axial direction, so that the through groove 102 and the mating blind groove 202 are radially opposite; the fixing clip 112 is provided on the bushing intermediate section 1112 and is configured to be fixed to the vehicle structure 20.

[0051] The bushing body 111 is tubular in shape and includes a first flange section 1111, a bushing intermediate section 1112, and a second flange section 1113 connected sequentially along the axial direction. The outer diameters of the first flange section 1111 and the second flange section 1113 are larger than those of the bushing intermediate section 1112, so that an installation groove for mounting the fixing clip 112 is formed in the bushing intermediate section 1112. The through groove 102 is provided on the second flange section 1113. After the rotating member 200 is installed in the first through hole 101, the rotating member 200 can abut against the end of the first flange section 1111 along the axial direction. At this time, the through groove 102 and the mating blind groove 202 are radially opposite, thereby realizing the positioning of the through groove 102 and the mating blind groove 202, which is conducive to the installation of the fixing spring 120. The inner wall of the fixing clip 112 is fitted on the bushing intermediate section 1112 to fix the pipeline installation structure 10 to the vehicle structure 20.

[0052] Considering the fixing of the pipeline installation structure 10 on the vehicle structure 20, in some embodiments, the fixing clip 112 includes two fixing parts 1121 arranged radially spaced apart and a mating part 1122 connected between the two fixing parts 1121. The mating part 1122 fits radially against the middle section 1112 of the connecting bushing. Each fixing part 1121 is provided with a fixing through hole 1123 for fasteners (not labeled) to pass through and be fixed to the vehicle structure 20.

[0053] refer to Figure 2 and Figure 3 As can be seen, the fixing clip 112 is shaped like an "Ω" and is made of sheet metal. The fixing clip 112 includes two fixing parts 1121 arranged radially apart and a mating part 1122 connected between the two fixing parts 1121. The inner surface of the mating part 1122 is in the shape of a semi-circular ring to fit snugly with the middle section 1112 of the bushing. The two fixing parts 1121 are fixing ears, which are provided with fixing through holes 1123 for fasteners (such as bolts) to pass through and be fixedly connected to the vehicle structure 20.

[0054] Continue to refer to Figure 2 and Figure 3 In some embodiments, the rotating member 200 includes a third flange section 210 and a rotating shaft section 220 connected axially, the third flange section 210 and the rotating shaft section 220 together forming a second through hole 201; the rotating shaft section 220 is arranged in the first through hole 101 and can rotate along the inner peripheral wall of the first through hole 101, and a mating blind groove 202 is provided at the end of the rotating shaft section 220 away from the third flange section 210; the end of the third flange section 210 facing the rotating shaft section 220 abuts against the first flange section 1111 axially, so that the mating blind groove 202 and the through groove 102 are radially opposite.

[0055] The third flange section 210 is disposed outside the first through hole 101, and the rotating shaft section 220 is disposed inside the first through hole 101. The outer peripheral wall of the rotating shaft section 220 is adapted to the inner peripheral wall of the first through hole 101 so as to rotate along the inner peripheral wall of the first through hole 101. The mating blind groove 202 is disposed at the end of the rotating shaft section 220 away from the third flange section 210. After the rotating member 200 is installed in the first through hole 101, the end of the third flange section 210 facing the rotating shaft section 220 abuts against the first flange section 1111 axially, so that the mating blind groove 202 and the through groove 102 are radially opposite each other, which is beneficial to the positioning of the rotating member 200 and the fixing member 100 when the retaining ring 120 is installed.

[0056] In this embodiment, both the rotating component 200 and the bushing body 111 can be made of self-lubricating nylon material to reduce the friction during the rotation of the rotating component 200, making the rotation of the rotating component 200 more flexible under the drive of the pipeline 30, and further improving the service life of the pipeline 30.

[0057] The rotating component 200 in this embodiment of the present invention can be integrally formed or can be formed by connecting separate components.

[0058] In some embodiments, when the rotating component 200 adopts a split structure, the rotating component 200 includes a first half-shaft 230 and a second half-shaft 240, both of which include a third flange section 210 and a rotating shaft section 220; the first half-shaft 230 and the second half-shaft 240 are snapped together to fix the pipeline 30 in the second through hole 201.

[0059] Both the first half-shaft 230 and the second half-shaft 240 include a third flange section 210 and a rotating shaft section 220, which together form a second through hole 202. When the pipeline 30 is installed, the first half-shaft 230 and the second half-shaft 240 can be arranged opposite each other on both sides of the pipeline 30 along the axial direction, and then snapped together to fix the pipeline 30 in the second through hole 201, so as to improve the installation efficiency of the pipeline 30.

[0060] To facilitate the disassembly and connection of the first half-shaft 230 and the second half-shaft 240, refer to Figures 2-4 As shown, in some embodiments, the first half-shaft 230 is provided with at least one first locking pin 231 and at least one first countersunk hole 232 on the side facing the second half-shaft 240, and the second half-shaft 240 is provided with a corresponding second countersunk hole 242 and a second locking pin 241; the first locking pin 231 is engaged with the second countersunk hole 242, and the first countersunk hole 232 is engaged with the second locking pin 241.

[0061] In this embodiment, both the first locking pin 231 and the second locking pin 241 are cylindrical, and both the first countersunk hole 232 and the second countersunk hole 242 are circular countersunk holes. Two first locking pins 231 and two first countersunk holes 232 are provided on the side of the first half-shaft 230 facing the second half-shaft 240. The two first locking pins 231 are respectively arranged diagonally on the side of the first half-shaft 230 facing the second half-shaft 240, and the two first countersunk holes 232 are distributed at the other two corners. That is, each first countersunk hole 232 is spaced apart from the adjacent first locking pin 231 along the axial and radial directions. The second half-shaft 240 is provided with corresponding second countersunk holes 242 and second locking pins 241. The first locking pins 231 and second countersunk holes 242 are engaged, and the first countersunk holes 232 and second locking pins 241 are engaged, thereby achieving a detachable connection between the first half-shaft 230 and the second half-shaft 240 to ensure no relative displacement between the first half-shaft 230 and the second half-shaft 240 along the axial and radial directions, thus improving their fit stability.

[0062] It should be noted that, in this embodiment of the present invention, the first through hole 101 is preferably set as a round hole to take into account the rotation of the rotating member 200, and the second through hole 202 on the rotating member 200 can be designed as a round hole or an irregular hole according to the outer contour of the pipeline 30.

[0063] To facilitate the fixing of the pipeline 30, in some embodiments, at least one axially extending mounting groove 2011 is symmetrically provided at the opposite ends of the first half-shaft 230 and the second half-shaft 240, and multiple mounting grooves 2011 together form a second through hole 201 for fixing the pipeline 30.

[0064] In this embodiment, the mounting slot 2011 can be configured with one, two, three, or four or more slots depending on the number of pipes and wires to be accommodated. For example, such as Figure 5 As shown, when the pipeline 30 is composed of four wire harnesses or flexible hoses with circular cross-sections, three axially extending mounting slots 2011 are symmetrically provided at opposite ends of the first half-shaft 230 and the second half-shaft 240 to accommodate the pipeline 30. The mounting slots 2011 on the second half-shaft 240 and the first half-shaft 230 are symmetrical to each other and together form the second through hole 201, so that the pipeline 30 can be tightly fitted with the inner wall of the mounting slot 2011 and stably fixed in the rotating part 200.

[0065] refer to Figure 3In some embodiments, the retaining ring 120 includes a connecting section 121, two clamping sections 122, and two guide sections 123; the two clamping sections 122 are respectively connected to both ends of the connecting section 121, and each clamping section 122 is connected to a guide section 123 at the end away from the connecting section 121; the connecting section 121 is fitted to the outer peripheral wall surface of the retaining sleeve 110; the clamping sections 122 are disposed in the mating blind groove 202 through the through groove 102 in a radial direction; the two guide sections 123 form an opening for guiding the clamping sections 122 as they pass through the through groove 102 in a radial direction.

[0066] The fixed snap ring 120 can be made of steel wire with a circular or rectangular cross section. The connecting section 121 can be clamped by an external clamp during the installation and disassembly of the fixed snap ring 120. When the fixed snap ring 120 is installed, the bushing body 111 is first located in the opening formed by the two guide sections 123. Then, the two guide sections 123 move radially through the through groove 102 and then move along the mating blind groove 202 and extend out. At this time, the clamping section 122 is located in the mating blind groove 202, completing the axial fixation of the rotating part 200 relative to the fixed part 100. The two can rotate relative to each other axially without axial displacement.

[0067] refer to Figure 6 In some embodiments, the first flange segment 1111 is provided with a plurality of drainage grooves 1111a at intervals along the circumference at one end of the first flange segment 1111 that is axially opposite to the third flange segment 210. The drainage grooves 1111a can play the role of draining and removing sand, reducing the wear between the first flange segment 1111 and the third flange segment 210 during rotation. In addition, it can also reduce the contact area between the first flange segment 1111 and the third flange segment 210 and reduce the rotational resistance.

[0068] refer to Figure 7 and Figure 8 As shown, another embodiment of the present invention also provides an automobile 1000, including the pipeline installation structure 10 as described above, and also including a vehicle structure 20 and a pipeline 30; the fastener 100 is fixedly connected to the vehicle structure 20; the pipeline 30 is fixedly disposed in the second through hole 201 so as to drive the rotating member 200 to rotate along the inner peripheral wall of the first through hole 101 during the torsion process.

[0069] In summary, the pipeline installation structure 10 and automobile 1000 provided by this utility model embodiment are optimized through the pipeline installation structure 10. The pipeline 30 configured on the corner module can be partially fixed in the second through hole 201 of the rotating member 200 through the pipeline installation structure 10. The fixing member 100 is fixed to the vehicle structure 20. When the wheel turns, the pipeline 30 undergoes torsional motion, which can drive the rotating member 200 to rotate in the first through hole 101. This reduces the torsional shear stress generated during the torsion of the pipeline 30, thereby meeting the steering requirements of the corner module while suppressing fatigue damage caused by long-term torsion of the pipeline 30, and thus effectively improving the service life of the pipeline 30.

[0070] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
