Description

Technical Field

[0001] This utility model relates to the field of vehicle air conditioning system technology, specifically to an air conditioning pipe fixing clamp. Background Technology

[0002] In vehicle air conditioning systems, proper pipe securing is crucial for stable system operation. It not only affects the efficient flow of refrigerant or air but also directly impacts the vehicle's vibration control, noise levels, and lifespan. A proper securing method effectively prevents pipe loosening, wear, or even breakage caused by vibrations during vehicle operation, ensuring the long-term reliable operation of the air conditioning system.

[0003] Traditional pipe fixing methods typically use metal clamps or individually secure each pipe. However, due to the limited interior space and complex structure of vehicles, this approach has several drawbacks: individually securing each pipe increases installation complexity and cost. Each pipe requires individual handling and precise positioning to avoid conflicts with other components, making the assembly process particularly cumbersome. This not only increases workload but can also prolong installation time, impacting overall production efficiency. Furthermore, the need for individual fixing devices for each pipe increases the weight of the entire system, negatively affecting overall vehicle performance. Insufficient spacing and arrangement of pipes occupy significant space and can hinder airflow, affecting the efficiency of the air conditioning system. This is especially problematic in complex vehicle models, such as hybrid or electric vehicles, where interior space is even more precious, and any unnecessary encroachment restricts the placement of other critical components. Simultaneously, traditional fixing methods may not provide sufficient flexibility to address the changing needs of different vehicle models, reducing design and production adaptability. In such cases, the limitations of traditional fixing methods are particularly evident, as they neither effectively utilize limited space nor meet the demands of modern automotive manufacturing for efficient assembly processes. Therefore, although these methods were widely used in the past, they are clearly no longer the optimal choice in the context of the current increasing demands for vehicle space utilization and assembly efficiency. Utility Model Content

[0004] The present invention aims to provide an air conditioning pipe fixing clamp with strong structural stability, simple and compact design, saving installation space, simple assembly process, high flexibility, improved assembly efficiency, easy mass production, and low manufacturing cost.

[0005] The basic solution provided by this utility model is: an air conditioning pipe fixing clamp, including a first clamp body and a second clamp body;

[0006] The first pipe clamp and the second pipe clamp are each provided with at least two arc-shaped grooves and mounting holes located between adjacent arc-shaped grooves; the first pipe clamp and the second pipe clamp are joined together so that at least two pipe cavities are formed through at least two arc-shaped grooves, and the axes of adjacent pipe cavities are parallel and have a first center distance, so that the mounting holes are coaxially corresponding, and the axial direction of the mounting holes is perpendicular to the axial direction of the pipe cavity and avoids the pipe cavity.

[0007] Both sides of the first and second pipe clamps are provided with a portion of the engaging connector, so that the first and second pipe clamps can engage axially along the mounting hole when they are assembled.

[0008] The working principle and advantages of this utility model are as follows:

[0009] Compared to existing technologies, this solution features a systematically optimized pipe clamp structure, enhancing its flexibility during assembly and stability after fixing from multiple dimensions. It also accelerates the adaptation and optimization design of the pipe clamp structure to changes in air conditioning piping. By adopting a modular design, the pipe clamp can form multiple cavities to accommodate pipes during assembly, enabling simultaneous installation of multiple pipes without individual fixing, significantly improving assembly efficiency and effectively saving installation space. Furthermore, the snap-fit ​​connectors and mounting holes are designed with a unidirectional layout, reinforcing each connection method and further enhancing the overall structural stability. This better meets the high stability requirements of the piping fixing system under complex road conditions during long-term vehicle operation. More importantly, this design achieves adjustable and controllable positioning during the multi-stage installation process of assembly, snap-fit, and bolt fixing: the approximate installation position can be determined in the initial assembly stage, local fine-tuning can be performed during snap-fit, and precise positioning is achieved through bolt tightening. This not only ensures installation accuracy but also provides flexible space for the arrangement of other surrounding components. This solution is suitable for fixing rigid air conditioning pipes with diameters ranging from 9 to 16 mm, especially for 16 mm, 12 mm and 9 mm. When the pipes are arranged side by side, the center distance of the pipe clamps is designed to be 27-35 mm, which further reduces the overall space occupied and helps to achieve a more compact and efficient layout in the vehicle interior.

[0014] The markings in the accompanying drawings include: first pipe clamp 1, second pipe clamp 2, arc groove 3, anti-slip texture 31, mounting hole 4, pipe cavity 5, snap-fit ​​connector 6, first section 61, second section 62, weight reduction groove 7, air conditioning pipe 8. Detailed Implementation

[0015] The following detailed explanation illustrates the specific implementation methods:

[0016] The basic implementation examples are as follows: Figure 1 , Figure 2 and Figure 3 As shown: An air conditioning pipe fixing clamp includes a first clamp body 1 and a second clamp body 2;

[0017] The first pipe clamp body 1 and the second pipe clamp body 2 are each provided with at least two arc-shaped grooves 3 and mounting holes 4 located between adjacent arc-shaped grooves 3; the first pipe clamp body 1 and the second pipe clamp body 2 are joined together so that at least two pipe cavities 5 are formed through at least two arc-shaped grooves 3, and the axes of adjacent pipe cavities 5 are parallel and have a first center distance, so that the mounting holes 4 are coaxially corresponding, and the axial direction of the mounting holes 4 is perpendicular to the axial direction of the pipe cavity 5 and avoids the pipe cavity 5;

[0018] Both sides of the first and second pipe clamps are provided with a portion of the engaging connector 6, so that the first and second pipe clamps can engage axially along the mounting hole 4 when they are assembled.

[0019] Specifically:

[0020] The first pipe clamp body 1 and the second pipe clamp body 2 are made of plastic and have an overall rectangular structure, with the pipe cavity and mounting hole completely penetrating the main body. The plastic pipe clamps are lightweight, helping to reduce the overall structural load; they possess excellent corrosion resistance, maintaining stable performance even in harsh environments, reducing maintenance needs; simultaneously, plastic materials can be precision injection molded to achieve complex designs and high consistency, simplifying the installation process and reducing production costs; furthermore, plastic pipe clamps can effectively absorb and disperse vibrations and impacts generated by vehicle movement or equipment operation, reducing stress concentration and lowering the risk of fatigue damage to the pipeline system. More importantly, the plastic material has a certain degree of flexibility and elasticity, allowing the pipe clamps to deform appropriately during installation to compensate for diameter errors, ensuring a secure clamping while avoiding damage to the pipeline.

[0021] Each of the six segments of the snap-fit ​​connector is located in the middle of the corresponding side of the pipe clamp body; the length of each six-segment snap-fit ​​connector occupies two-thirds to three-quarters of the length of the corresponding side of the pipe clamp body. This size and position design can improve the firmness of the snap-fit ​​connection and improve the stability and reliability of the overall fixed assembly.

[0022] The engaging connectors 6 on the first pipe clamp body 1 and the second pipe clamp body 2 may have the same or different portions. Specifically, the engaging connectors 6 include a first portion 61 and a second portion 62. When the portions of the engaging connectors 6 on the first pipe clamp body 1 and the second pipe clamp body 2 are the same, that is, the first pipe clamp body 1 has either a first portion 61 or a second portion 62 on both sides, and the second pipe clamp body 2 has either a second portion 62 or a first portion 61 on both sides. This method facilitates unidirectional engagement and is convenient for operation. When the portions of the engaging connectors 6 on the first pipe clamp body 1 and the second pipe clamp body 2 are different, that is, the first pipe clamp body 1 and the second pipe clamp body 2 have a first portion 61 and a second portion 62 on both sides respectively. The first portion 61 on the first pipe clamp body 1 and the second portion 62 on the second pipe clamp body 2 are in corresponding positions, and the second portion 62 on the first pipe clamp body 1 and the first portion 61 on the second pipe clamp body 2 are in corresponding positions. This method allows engagement from two directions, improving the firmness of the engagement.

[0023] like Figure 1 and Figure 2 As shown, each arc groove 3 is provided with anti-slip texture 31. The anti-slip texture 31 can be set along the length of the arc groove 3 and adopts toothed texture. The tooth shape can be rectangular. The width of the protrusion and the groove of the tooth shape can be the same or different, which improves the stability of the pipeline fixing.

[0024] like Figure 1 As shown, several weight-reducing grooves 7 are formed on one side of the arc-shaped groove 3 on the first pipe clamp body 1 and / or the second pipe clamp body 2. The weight-reducing grooves 7 further reduce the weight of the pipe clamp while ensuring its fixation stability, thus simultaneously reducing manufacturing costs. The distance between the bottom of each weight-reducing groove 7 and the corresponding side of the arc-shaped groove 3 meets the minimum thickness requirement, which can be 2-5mm. This method ensures that while reducing weight and cost, the weight-reducing grooves 7 must also guarantee the stability of the air conditioning control system, preventing any area from becoming too thin, which would result in insufficient mechanical strength of the material and make it prone to brittle fracture under external impact or long-term stress.

[0025] The number of pipe cavities 5 is not less than the number of air conditioning pipes in the air conditioning pipe 8. In this embodiment, there are two air conditioning pipes in the air conditioning pipe 8, and two corresponding pipe cavities 5 are provided with different diameters, which can simultaneously accommodate air conditioning pipes with the same path but different diameters. The diameter of the pipe cavity 5 is in the range of 9-16mm, preferably 9mm, 12mm, or 16mm. When there are two pipe cavities 5, they can be combined in pairs, such as 9mm and 12mm, 9mm and 16mm, or 12mm and 16mm. The first center distance is 27-35mm. The size of the mounting hole 4 is in the range of 6.5-9.5mm. The overall combined width is 50-60mm, which can achieve a compact layout.

[0026] In practical use:

[0027] like Figure 4 As shown, two air conditioning pipes correspond to two pipe cavities 5. The first pipe clamp 1 is placed below the air conditioning pipe 8, with each arc-shaped groove 3 corresponding to a matching air conditioning pipe. The second pipe clamp 2 is placed above the first pipe clamp 1, with its two arc-shaped grooves 3 corresponding to the matching arc-shaped grooves 3 of the first pipe clamp 1. The mounting holes 4 of the second pipe clamp 2 correspond to the mounting holes 4 of the first pipe clamp 1. After adjusting to a suitable position, the first pipe clamp 1 and the second pipe clamp 2 are engaged using the snap-fit ​​connector 6. The two arc-shaped grooves 3 together form a pipe cavity 5, each surrounding the corresponding air conditioning pipe. The position can be finely adjusted. Finally, bolts are used to pass through the mounting holes 4 for final fixation, thus completing the simultaneous assembly and fixing of the two air conditioning pipes. The overall pipe clamp is fixed to the vehicle frame or body, securing the rigid portion of the air conditioning pipe. The spacing between adjacent pipe clamps on a single pipe is 180mm-250mm, ensuring more reliable installation strength.

[0028] In other embodiments, there can be two or more pipe cavities 5, such as three, which can simultaneously fix air conditioning pipes with three air conditioning pipes; of course, in special circumstances, the pipe clamp with three pipe cavities 5 can also be used to fix air conditioning pipes with two air conditioning pipes as an emergency backup, improving the versatility of the pipe clamp in this solution, and at the same time facilitating the rapid adaptation design of the pipe clamp in this solution.

[0029] This embodiment provides an air conditioning pipe fixing clamp, which features a systematically optimized structure, enhancing its flexibility during assembly and stability after fixing from multiple dimensions. By adopting a modular design, the clamp can form multiple cavities to accommodate pipes during assembly, enabling simultaneous installation of multiple pipes without the need for individual fixing, significantly improving assembly efficiency and effectively saving installation space. Furthermore, the snap-fit ​​connectors and mounting holes are designed with a unidirectional layout, reinforcing each connection method and further enhancing the overall structural stability. This better meets the high stability requirements of the pipe fixing system under complex road conditions during long-term vehicle operation. More importantly, this design allows for adjustable and controllable positioning during the multi-stage installation process of assembly, snap-fit, and bolt fixing: the approximate installation position can be determined in the initial assembly stage, local fine-tuning can be performed during snap-fit, and precise positioning is achieved through bolt tightening. This not only ensures installation accuracy but also provides flexible space for the arrangement of other surrounding components. This solution is suitable for fixing rigid air conditioning pipes with diameters ranging from 9 to 16 mm, especially for 16 mm, 12 mm and 9 mm. When the pipes are arranged side by side, the center distance of the pipe clamps is designed to be 27-35 mm, which further reduces the overall space occupied and helps to achieve a more compact and efficient layout in the vehicle interior.
