Description

Technical Field

[0001] This application relates to the field of vehicle design and manufacturing technology, and in particular to a pipeline installation structure and a vehicle. Background Technology

[0002] To ensure the normal operation of the vehicle, a large number of pipelines with various functions are installed inside the vehicle, such as cooling water pipes and various types of electrical control wiring harnesses.

[0003] Currently, when installing pipelines, they are generally installed in the middle of the vehicle floor or on both sides of the door sill. Both of these arrangements have drawbacks. When the pipelines are placed in the middle of the vehicle, the central channel of the lower crossbeam in the front engine compartment needs to be disconnected, resulting in poor force transmission and affecting the performance of the body-in-white. When the pipelines are placed on both sides of the door sill, it limits the battery pack capacity and makes the pipeline harness more susceptible to damage during a collision.

[0004] Due to road conditions, vehicles may experience bumps while driving. At this time, the internal pipelines of the vehicle are prone to movement, which can lead to problems such as collision and friction between the pipelines and the internal structure of the vehicle body, as well as twisting and deformation of the pipelines themselves, resulting in damage to the pipelines and reducing their service life. Summary of the Invention

[0005] This application provides a pipeline installation structure and a vehicle to solve the technical problem that existing pipelines are prone to movement and damage.

[0006] According to one aspect of this application, a pipeline installation structure is provided, including a fastener and an installation assembly; the fastener has a hollow cavity for accommodating a pipeline; the installation assembly is connected to the fastener and disposed within the hollow cavity, the installation assembly having an installation hole for installing a pipeline such that the installation assembly separates the pipeline from the fastener.

[0007] The pipeline installation structure provided in this application includes a fixing member and an installation component. The installation component is disposed within the hollow cavity enclosed by the fixing member and has installation holes for installing pipelines. When pipelines need to be installed, the pipeline is connected to the installation component by passing it through the installation holes. At this time, both the pipeline and the installation component are located within the hollow cavity of the fixing member, and the fixing member protects the pipeline from damage. Simultaneously, the installation component separates the pipeline from the fixing member, preventing direct contact between the pipeline and the fixing member. Therefore, even if the pipeline moves, such as during vibration, it will not rub against the fixing member, further preventing pipeline damage and extending its service life.

[0008] In a further preferred embodiment, the mounting assembly includes an outer mounting ring and an inner mounting ring, the outer mounting ring being sleeved outside the inner mounting ring and connected to the fastener, and the inner mounting ring having the mounting hole.

[0009] In this design, an outer mounting ring is fitted over an inner mounting ring and connected to a fastener, allowing the inner mounting ring to rotate relative to both the outer and fasteners. During this rotation, the inner ring compresses the outer mounting ring, causing partial deformation that abuts against the inner wall of the fastener's hollow cavity. This secures both the outer and inner mounting rings within the hollow cavity, facilitating the assembly of the mounting component with the fastener. This method allows for easy installation of the mounting component within the hollow cavity, thus enabling efficient pipeline installation.

[0010] In a further preferred embodiment, the outer mounting ring includes a connector and a plurality of limiting members. The connector is sleeved outside the inner mounting ring and spaced apart from the inner mounting ring. The plurality of limiting members are connected to the connector and the fixing member, and the plurality of limiting members are distributed circumferentially along the mounting hole and respectively abut against the corresponding part of the inner mounting ring.

[0011] In this design, the connector serves as the mounting base for multiple limiting components. These limiting components are positioned at different locations on the inner mounting ring to cooperate with the inner ring and facilitate assembly with the fixing components. Specifically, when the inner mounting ring rotates, it compresses the multiple limiting components, causing them to protrude from the connector and abut against the inner wall of the hollow cavity. This secures the inner mounting ring within the hollow cavity from multiple angles, thus completing the assembly of the mounting component with the fixing components. Consequently, when the pipeline is installed in the mounting hole of the inner mounting ring, the inner ring and the limiting components can separate the pipeline from the fixing components, effectively preventing damage caused by contact and friction between the pipeline and the fixing components.

[0012] In a further preferred embodiment, the connector is provided with a connecting hole that extends radially through the connector along the mounting hole; the limiting member is disposed in the connecting hole, with one end of the limiting member extending out of the connecting hole to abut against the mounting inner ring and the other end extending out of the connecting hole to abut against the fixing member.

[0013] In this design, by providing a connecting hole in the connector and connecting the limiting member to the connector via the connecting hole, the limiting member can deform along the extension direction of the connecting hole. Therefore, when the inner mounting ring rotates and presses against the limiting member, the limiting member deforms along the extension direction of the connecting hole and abuts against the inner wall of the fixing member, thereby allowing the outer mounting ring and the inner mounting ring to be installed within the hollow cavity of the fixing member, facilitating pipeline installation.

[0014] In a further preferred embodiment, the limiting member includes a buffer portion and a limiting portion; the buffer portion and the limiting portion are arranged radially in the connecting hole along the mounting hole, a portion of the limiting portion extends out of the connecting hole to abut against the mounting inner ring, and a portion of the buffer portion extends out of the connecting hole to abut against the fixing member.

[0015] In this design, the limiting part contacts the inner mounting ring and transmits the compressive force generated by the inner mounting ring's rotation to the buffer part. The buffer part can be made of a deformable material, preferably a soft material, allowing it to deform to absorb the compressive force generated by the inner mounting ring's rotation, thus ensuring that the outer and inner mounting rings are securely engaged within the hollow cavity of the fastener. Furthermore, since the buffer part needs to contact the inner wall of the fastener, using a soft material prevents damage to the inner wall surface, extending the fastener's service life.

[0016] In a further preferred embodiment, the limiting portion is provided with a first arc-shaped surface, which is used to abut against the mounting inner ring so that the mounting inner ring can rotate relative to the first arc-shaped surface along the circumference of the mounting hole.

[0017] In this design, the first arc-shaped surface on the limiting part is used to abut against the inner mounting ring. When the inner mounting ring rotates, it can move relative to the first arc-shaped surface. At this time, due to the arc design of the first arc-shaped surface, the friction between the inner mounting ring and the limiting part can be reduced, which is beneficial to improving the installation efficiency of pipelines, mounting components and fasteners.

[0018] In a further preferred embodiment, the mounting inner ring includes multiple limiting segments and multiple connecting segments, which are staggered and connected to form the mounting hole; the limiting segments protrude radially from the connecting segments of the mounting hole and abut against the limiting portion.

[0019] In this design, the limiting section protrudes radially from the connecting section along the mounting hole. As the inner mounting ring rotates, when the limiting section contacts and abuts against the limiting part, it can compress the limiting part, thus assembling the outer and inner mounting rings with the fastener. As the inner mounting ring continues to rotate, when the compressive force of the limiting section on the limiting part decreases to a certain value, it becomes insufficient to cause sufficient deformation of the buffer part. At this point, the outer and inner mounting rings disengage from the hollow cavity, allowing for the disassembly of the mounting components and fasteners. This method facilitates the rapid and efficient connection or disconnection of pipelines and mounting components with fasteners, enabling efficient pipeline installation and removal.

[0020] In a further preferred embodiment, the limiting segment is provided with a second arcuate surface for abutting against the limiting portion.

[0021] In this design, the second arc-shaped surface on the limiting section is used to abut against the limiting part. When the inner ring rotates, the second arc-shaped surface of the limiting section of the inner ring can move relative to the limiting part. At this time, due to the arc design of the second arc-shaped surface, the friction between the inner ring and the limiting part can be reduced, which is beneficial to improving the installation efficiency of pipelines, installation components and fasteners.

[0022] In a further preferred embodiment, the connecting segment is provided with a fixing groove, and the connecting member is provided with a fixing protrusion. The fixing protrusion is used to cooperate with the fixing groove to restrict the circumferential rotation of the mounting inner ring along the mounting hole.

[0023] In this solution, after the mounting components and fasteners are assembled by rotating the inner mounting ring, the fixing protrusion on the outer mounting ring and the fixing slot on the inner mounting ring can be used to restrict the inner mounting ring from continuing to rotate, thereby ensuring the precise positioning of the inner mounting ring and ensuring a stable connection between the inner and outer mounting rings and the fasteners.

[0024] According to another aspect of this application, a vehicle is provided, including a sill assembly, a battery pack assembly, wiring, and a wiring mounting structure as described in any of the above; the fastener is connected to the sill assembly and the battery pack assembly; the wiring passes through the mounting hole of the mounting assembly.

[0025] The vehicle provided in this application includes the aforementioned pipeline mounting structure, with its fasteners connected to the door sill assembly and the battery pack assembly. During pipeline installation, the pipeline is simply passed through the mounting holes of the pipeline mounting structure to connect it to the structure, thus protecting the pipeline from damage. Furthermore, the pipeline mounting structure separates the pipeline from the door sill assembly and the battery pack assembly, preventing direct contact and friction, further avoiding damage and extending the pipeline's lifespan. This also optimizes the vehicle's structure, thereby improving vehicle safety.

[0026] In summary, the pipeline installation structure and vehicle provided in this application have at least the following beneficial effects:

[0027] The vehicle provided in this application includes a pipeline mounting structure, which comprises a fixing member and a mounting assembly. The fixing member is connected to the sill assembly and the battery pack assembly, and the mounting assembly is disposed within the hollow cavity enclosed by the fixing member. When a pipeline needs to be installed, the pipeline is connected to the mounting assembly by passing it through the mounting hole on the mounting assembly. At this time, both the pipeline and the mounting assembly are located within the hollow cavity of the fixing member, and the fixing member protects the pipeline from damage. Furthermore, the mounting assembly separates the pipeline from the fixing member, and the fixing member also separates the pipeline from the sill assembly and the battery pack assembly, preventing direct contact between the pipeline and the fixing member, sill assembly, and battery pack assembly. Therefore, even if the pipeline moves, such as during pipeline vibration, it will not rub against the fixing member, sill assembly, and battery pack assembly, thereby further preventing pipeline damage, extending pipeline lifespan, optimizing the vehicle body structure, and ultimately improving vehicle safety.

[0044] The vehicle provided according to the embodiments of this application can be a fuel-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. The following embodiments use an electric vehicle as an example. Specifically, the vehicle of this application includes a door sill assembly 20, a battery pack assembly 30, a pipeline 40, and a pipeline mounting structure 10. The fixing member 100 of the pipeline mounting structure 10 is connected to the door sill assembly 20 and the battery pack assembly 30; the pipeline 40 of the pipeline mounting structure 10 passes through the mounting hole 221 of the mounting component 200. Because the vehicle of this application uses the pipeline mounting structure 10, based on the structural design of the pipeline mounting structure 10 itself, when installing the pipeline 40, simply passing the pipeline 40 through the mounting hole 221 of the pipeline mounting structure 10 achieves the connection between the pipeline 40 and the pipeline mounting structure 10. At this time, the pipeline mounting structure 10 can protect the pipeline 40 from damage. Furthermore, the pipeline installation structure 10 can separate the pipeline 40 from the door sill assembly 20 and the battery pack assembly 30, preventing the pipeline 40 from directly contacting and rubbing against the door sill assembly 20 and the battery pack assembly 30. This further avoids damage to the pipeline 40, helps extend its service life, optimizes the vehicle body structure, and improves vehicle safety.

[0045] Please refer to Figure 1-5 The pipeline installation structure 10 provided in this application embodiment includes at least a fastener 100 and an installation component 200.

[0046] The fastener 100 is disposed between the door sill assembly 20 and the battery pack assembly 30, and is connected to both the door sill assembly 20 and the battery pack assembly 30. For example, the fastener 100 can be assembled from multiple plate-like structures and connected to the door sill assembly 20 and the battery pack assembly 30 by bolts. The fastener 100 has a hollow cavity 110 for accommodating the pipelines 40 inside the vehicle. The pipelines 40 include various pipes and wiring harnesses inside the vehicle, such as coolant pipes, brake pipes, high-voltage wiring harnesses, and various types of electronic control wiring harnesses.

[0047] The mounting assembly 200 is connected to the fixing member 100 and disposed within the hollow cavity 110. The mounting assembly 200 has a mounting hole 221 for mounting the pipeline 40. The mounting hole 221 can be configured to fit the shape of the pipeline 40. For example, when the pipeline 40 has a circular cross-section, the mounting hole 221 is configured as a circular hole that mates with the circular cross-section, so that the pipeline 40 can fit tightly with the mounting hole 221 when passing through it, thereby fixing the pipeline 40 using the mounting assembly 200. Since the mounting assembly 200 is disposed between the fixing member 100 and the pipeline 40, the mounting assembly 200 can be used to separate the pipeline 40 from the fixing member 100.

[0048] With the above structural design, when installing the pipeline 40 inside the vehicle, the pipeline 40 can be connected to the mounting assembly 200 by passing it through the mounting hole 221 on the mounting assembly 200. At this time, both the pipeline 40 and the mounting assembly 200 are located within the hollow cavity 110 of the fixing member 100, and the fixing member 100 can protect the pipeline 40 from damage. Furthermore, the mounting assembly 200 can separate the pipeline 40 from the fixing member 100, and the fixing member 100 can also separate the pipeline 40 from the door sill assembly 20 and the battery pack assembly 30, so that the pipeline 40 does not directly contact the fixing member 100, the door sill assembly 20 and the battery pack assembly 30. This further avoids friction damage between the pipeline 40 and the fixing member 100, the door sill assembly 20 and the battery pack assembly 30, which helps to extend the service life of the pipeline 40, optimizes the vehicle body structure, and thus improves vehicle safety.

[0049] In existing technologies, when installing pipelines 40 inside a vehicle, they are generally placed directly in narrow spaces within the vehicle or mounted directly on the surface of vehicle components, causing direct contact between the pipelines 40 and the vehicle body. This inevitably leads to friction or impact between the pipelines 40 and the body, easily damaging them. Furthermore, some vehicle models choose to place pipelines 40, such as coolant pipes, brake lines, and high-voltage harnesses, in the middle of the vehicle body. This requires adding corresponding pipeline channel structures in the middle of the vehicle floor, resulting in an uneven rear floor, affecting the comfort of rear passengers, and also causing poor force transmission within the vehicle body, impacting the performance of the body-in-white. In particular, for some electric vehicles, if the pipelines 40 are haphazardly placed within the vehicle body, they can easily occupy a large amount of space, limiting the space available for the battery pack and thus restricting its capacity.

[0050] Compared to existing technologies, the pipeline installation structure 10 in this embodiment can separate the pipeline 40 from the internal components of the vehicle body. On the one hand, the fixing member 100 can protect the pipeline 40 from damage during vehicle bumps or collisions. On the other hand, it can prevent the pipeline 40 from being damaged by direct contact and friction with the fixing member 100 or the vehicle body. Simultaneously, it can eliminate noise generated by pipeline 40 friction, which is beneficial to improving the vehicle's NVH (Noise, Vibration, Harshness) performance. Furthermore, the fixing member 100 can be connected to the gaps on the side of the battery pack assembly 30 and the bottom of the sill assembly 20, thus eliminating the need for a pipeline channel structure in the middle of the vehicle floor. This promotes a flat front and rear floor, improves passenger comfort, and ensures smooth force transmission in the middle of the vehicle floor, thereby improving the body-in-white's collision performance. In addition, the pipeline installation structure 10 in this embodiment can reduce interference between the pipeline 40 and the battery pack, which is beneficial to increasing the battery pack capacity and improving battery pack safety.

[0051] As a further preferred embodiment, based on the above-mentioned solution, the specific embodiments of this application may also include one or more of the following additions or combinations.

[0052] In some optional embodiments, there are multiple mounting components 200, which are arranged sequentially along the length of the hollow cavity 110, and the center lines of the mounting holes 221 of each mounting component 200 coincide. Fixing the pipeline 40 within the fixing member 100 using multiple mounting components 200 helps to improve the connection strength between the pipeline 40 and the fixing member 100, ensuring that the pipeline 40 is installed securely.

[0053] In some alternative embodiments, the mounting assembly 200 includes an outer mounting ring 210 and an inner mounting ring 220. The outer mounting ring 210 is sleeved outside the inner mounting ring 220 and connected to the fastener 100. The inner mounting ring 220 is provided with a mounting hole 221.

[0054] Reference Figure 3 Both the outer mounting ring 210 and the inner mounting ring 220 are approximately ring-shaped. The outer mounting ring 210 is fitted over the inner mounting ring 220 and connected to the fixing member 100, allowing the inner mounting ring 220 to rotate relative to the outer mounting ring 210 and the fixing member 100. The connection method between the pipeline 40 and the inner mounting ring 220 includes bonding the pipeline 40 to the mounting hole 221 or using an interference fit, etc., to ensure that the pipeline 40 and the mounting hole 221 can rotate together, thereby rotating the inner mounting ring 220 by rotating the pipeline 40.

[0055] During the rotation of the inner mounting ring 220, the inner mounting ring 220 can compress the outer mounting ring 210, causing a portion of the outer mounting ring 210 to deform and abut against the inner wall of the hollow cavity 110 of the fixing member 100. This allows the outer mounting ring 210 and the inner mounting ring 220 to be secured within the hollow cavity 110, thus assembling the mounting assembly 200 with the fixing member 100. This method of installing the mounting assembly 200 within the hollow cavity 110 simplifies the installation process and facilitates efficient installation of the pipeline 40 using the mounting assembly 200.

[0056] In some optional embodiments, the outer mounting ring 210 includes a connector 211 and a plurality of limiting members 212. The connector 211 is sleeved on the outer side of the inner mounting ring 220 and spaced apart from the inner mounting ring 220. The plurality of limiting members 212 are connected to the connector 211 and the fixing member 100. The plurality of limiting members 212 are distributed circumferentially along the mounting hole 221 and respectively abut against the corresponding part of the inner mounting ring 220.

[0057] Reference Figure 4The connector 211 has a generally annular structure, and there is a gap between the connector 211 and the mounting inner ring 220 extending radially along the mounting hole 221. The connector 211 serves as the mounting base for multiple limiting members 212, which are connected to the connector 211 and arranged in different positions on the mounting inner ring 220 to cooperate with the mounting inner ring 220 to achieve assembly with the fixing member 100. Specifically, when the mounting inner ring 220 rotates, it can compress the multiple limiting members 212, causing them to protrude from the connector 211 and abut against the inner wall of the fixing member 100, thereby securing the mounting inner ring 220 within the hollow cavity 110 from multiple positions, thus completing the assembly of the mounting assembly 200 and the fixing member 100. Therefore, when the pipeline 40 is installed in the mounting hole 221 of the mounting inner ring 220, the pipeline 40 can be separated from the fixing member 100 by the mounting inner ring 220 and the limiting member 212, thereby effectively preventing the pipeline 40 from contacting and rubbing against the fixing member 100 and causing damage.

[0058] In some optional embodiments, the connector 211 is provided with a connecting hole 2111, which extends radially through the mounting hole 221; the limiting member 212 is disposed in the connecting hole 2111, with one end of the limiting member 212 extending out of the connecting hole 2111 to abut against the mounting inner ring 220 and the other end extending out of the connecting hole 2111 to abut against the fixing member 100.

[0059] Reference Figure 3-5 By providing a connecting hole 2111 in the connector 211, and connecting the limiting member 212 to the connector 211 via the connecting hole 2111, the limiting member 212 can deform along the extending direction of the connecting hole 2111. Therefore, when the inner mounting ring 220 rotates and presses against the limiting member 212, the limiting member 212 can deform along the extending direction of the connecting hole 2111 and abut against the inner wall of the fixing member 100, thereby enabling the outer mounting ring 210 and the inner mounting ring 220 to be installed within the hollow cavity 110 of the fixing member 100, facilitating the installation of the pipeline 40.

[0060] In some alternative embodiments, the limiting member 212 includes a buffer portion 2121 and a limiting portion 2122; the buffer portion 2121 and the limiting portion 2122 are arranged radially in the connecting hole 2111 along the mounting hole 221, a portion of the limiting portion 2122 extends out of the connecting hole 2111 to abut against the mounting inner ring 220, and a portion of the buffer portion 2121 extends out of the connecting hole 2111 to abut against the fixing member 100.

[0061] Reference Figure 3 and Figure 5The limiting part 2122 is used to contact the mounting inner ring 220 and transmit the compressive force generated by the rotation of the mounting inner ring 220 on the limiting part 2122 to the buffer part 2121. The buffer part 2121 can be made of a deformable material, preferably a soft material, so that the buffer part 2121 itself can undergo a certain amount of deformation, so as to absorb the compressive force generated by the rotation of the mounting inner ring 220 on the limiting part 2122, thereby ensuring that the mounting outer ring 210 and the mounting inner ring 220 can be firmly engaged in the hollow cavity 110 of the fastener 100. Furthermore, since the buffer part 2121 needs to contact the inner wall of the fastener 100, by providing a soft buffer part 2121, damage to the inner wall surface of the fastener 100 can be avoided, which is beneficial to extending the service life of the fastener 100, and at the same time, it can reduce the vibration and noise generated by the contact friction between the buffer part 2121 and the inner wall surface of the fastener 100.

[0062] In some optional embodiments, the buffer portion 2121 is fixedly connected to the connector 211, and the limiting portion 2122 is movably disposed within the connecting hole 2111. For example, the limiting portion 2122 can be bonded to the buffer portion 2121. In this case, as the mounting inner ring 220 rotates, the mounting inner ring 220 can abut against and press the limiting portion 2122, thereby pressing the buffer portion 2121 so that the buffer portion 2121 protrudes outside the connecting hole 2111 to abut against the inner wall of the fastener 100, ultimately realizing the assembly of the mounting assembly 200 and the fastener 100.

[0063] In some optional embodiments, the limiting part 2122 is provided with a first arcuate surface 2122a, which is used to abut against the mounting inner ring 220 so that the mounting inner ring 220 can rotate relative to the first arcuate surface 2122a in the circumferential direction of the mounting hole 221.

[0064] Specifically, the first arc-shaped surface 2122a on the limiting part 2122 is used to abut against the mounting inner ring 220. When the mounting inner ring 220 rotates, the mounting inner ring 220 can move relative to the first arc-shaped surface 2122a. At this time, due to the arc-shaped design of the first arc-shaped surface 2122a, the friction between the mounting inner ring 220 and the limiting part 2122 can be reduced, which is beneficial to improving the installation efficiency of the pipeline 40 and the mounting assembly 200 and the fastener 100.

[0065] In some optional embodiments, the mounting inner ring 220 includes a plurality of limiting segments 222 and a plurality of connecting segments 223, which are staggered and connected to form a mounting hole 221; the limiting segments 222 protrude radially from the connecting segments 223 in the mounting hole 221 and abut against the limiting portion 2122.

[0066] Reference Figure 5The inner mounting ring 220 includes four limiting segments 222 and four connecting segments 223, while the outer mounting ring 210 includes four corresponding limiting portions 2122 and four buffer blocks. The four limiting segments 222 and four connecting segments 223 are staggered circumferentially along the mounting hole 221, with adjacent limiting segments 222 connected by a connecting segment 223. The connecting segment 223 is configured as a straight strip structure, and the limiting segments 222 are configured to protrude radially from the connecting segment 223 along the mounting hole 221. As the inner mounting ring 220 rotates, when the limiting section 222 contacts and abuts against the limiting part 2122, the limiting section 222 can squeeze the limiting part 2122, thereby assembling the outer mounting ring 210 and the inner mounting ring 220 with the fixing member 100. As the inner mounting ring 220 continues to rotate, when the squeezing force of the limiting section 222 on the limiting part 2122 decreases to a certain value, the squeezing force of the limiting section 222 on the limiting part 2122 is insufficient to cause sufficient deformation of the buffer part 2121. At this point, the outer mounting ring 210 and the inner mounting ring 220 disengage from the hollow cavity 110, thereby enabling the disassembly of the mounting assembly 200 from the fixing member 100. This method facilitates the rapid and efficient connection or disconnection of the pipeline 40 and the mounting assembly 200 from the fixing member 100, thereby achieving efficient installation or disassembly of the pipeline 40.

[0067] It should be understood that in the above embodiments, the purpose of providing four limiting segments 222 and four connecting segments 223 is to correspond to the four sides of the hollow cavity 110 of the fastener 100, so as to ensure the stability of the connection between the mounting assembly 200 and the fastener 100. In other optional embodiments, the number of limiting segments 222 and connecting segments 223 and the number of sides of the hollow cavity 110 are not limited to four, for example, they can also be three, five, six, etc.

[0068] In some alternative embodiments, the limiting segment 222 is provided with a second arcuate surface 2221 for abutting against the limiting portion 2122.

[0069] Specifically, the second arc-shaped surface 2221 on the limiting segment 222 can be used to abut against the first arc-shaped surface 2122a of the limiting part 2122. When the mounting inner ring 220 rotates, the second arc-shaped surface 2221 of the limiting segment 222 of the mounting inner ring 220 can move relative to the first arc-shaped surface 2122a of the limiting part 2122. At this time, due to the arc design of the second arc-shaped surface 2221, the friction between the mounting inner ring 220 and the limiting part 2122 can be further reduced, which is beneficial to improving the installation efficiency of the pipeline 40 and the mounting assembly 200 and the fastener 100.

[0070] In a further preferred embodiment, the connecting section 223 is provided with a fixing groove 2231, and the connecting member 211 is provided with a fixing protrusion 2112. The fixing protrusion 2112 is used to cooperate with the fixing groove 2231 to restrict the circumferential rotation of the mounting inner ring 220 along the mounting hole 221.

[0071] After the mounting inner ring 220 is assembled with the mounting component 200 and the fixing component 100 by rotating, the fixing protrusion 2112 on the mounting outer ring 210 and the fixing slot 2231 on the mounting inner ring 220 can be used to restrict the continued rotation of the mounting inner ring 220. This ensures that the mounting inner ring 220 is accurately positioned and that the mounting inner ring 220 and the mounting outer ring 210 are firmly connected to the fixing component 100. It also prevents the mounting inner ring 220 from rotating itself and causing the pipeline 40 to rotate, which would result in the pipeline 40 being unable to be fixed.

[0072] Furthermore, the fixing slot 2231 is preferably made of an elastic material, so that it has a certain deformation capability, so that when the mounting inner ring 220 rotates, the fixing slot 2231 on the mounting inner ring 220 can engage and limit the movement.

[0073] 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.
