TECHNICAL FIELD

[0001] The application belongs to the technical field of pipeline components, and particularly relates to an automobile air conditioner pipeline assembly. BACKGROUND

[0002] The pipeline refers to a pipeline for transmitting working fluid in a hydraulic system, and the air conditioner pipeline assembly is an important factor influencing the performance of an air conditioning system. The arrangement of the air conditioner pipeline is different for each vehicle model due to the differences in the engine compartment.

[0003] Patent No. CN219769591 U discloses an automobile air conditioner warm air system pipeline assembly, which comprises a water outlet pipe, a water inlet pipe and a support frame.

[0004] The above patent simply relies on the head interface and the tail interface for connection when the pipelines are connected, and the connection mode of the interfaces is flange connection, clamping connection, threaded connection or groove connection. Although the connection can be achieved, the sealing effect of the connection needs to be improved. SUMMARY

[0005] The application aims to provide an automobile air conditioner pipeline assembly which can solve the above problems.

[0006] The application aims to provide an automobile air conditioner pipeline assembly which comprises:

[0007] a first pipeline;

[0008] a second pipeline;

[0009] a docking mechanism arranged between the first pipeline and the second pipeline and used for connecting the first pipeline and the second pipeline, the docking mechanism comprising a first docking piece, a second docking piece and a fastener connecting the two docking pieces;

[0010] The first pipeline is embedded in the first docking piece, the second pipeline is embedded in the second docking piece, and the two pipelines are communicated through the two docking pieces.

[0011] The automobile air conditioner pipeline assembly comprises the above-mentioned automobile air conditioner pipeline assembly. Compared with the prior art which simply relies on the head interface and the tail interface and adopts the flange connection, clamping connection, threaded connection or groove connection mode, the automobile air conditioner pipeline assembly of the application embeds the first pipeline in the first docking piece and the second pipeline in the second docking piece, and then connects the two docking pieces through the fastener to communicate the two pipelines, which can more effectively ensure the sealing of the connection and solve the problem of poor sealing effect of the existing connection mode. At the same time, through the cooperation of the first docking piece, the second docking piece and the fastener, the installation mode can be made more simple and fast, and it is convenient for subsequent workers to regularly disassemble and protect the docking mechanism or replace and maintain the pipelines.

[0012] Further, the first connector comprises:

[0013] The first connector body is slidably arranged on the first pipeline;

[0014] The first insertion slot is arranged on the first connector body and passes through the first pipeline;

[0015] The first bolt hole is arranged on the first connector body and is adapted to the fastener;

[0016] Among them, the first bolt hole is arranged with multiple and is annularly distributed along the first insertion slot.

[0017] The first connector body is slidably arranged on the first pipeline, and when it is necessary to be connected with the second connector, the position of the first connector body can be adjusted by sliding to be more accurately aligned with the second connector, thereby reducing the installation difficulty and improving the installation efficiency. In addition, the first pipeline is also provided with a convex ring to prevent the first connector body from being separated. Meanwhile, the first insertion slot can ensure that the first pipeline can be accurately embedded in the first connector and can also fix the first pipeline to prevent displacement in the subsequent connection process and affect the subsequent sealing. In addition, the first bolt hole is arranged on the first connector body and is adapted to the fastener, and multiple first bolt holes are annularly distributed along the first insertion slot, so that the fastener can fix the first connector and the second connector from multiple directions, effectively improving the overall connection stability of the connector mechanism and ensuring that the two pipelines will not be loose or separated during long-term use. In addition, through the fastening effect of multiple bolt holes, the second sealing ring between the first connector and the second connector can be further compressed, further enhancing the sealing effect.

[0018] Further, the second connector comprises:

[0019] The second connector body;

[0020] The second insertion slot is arranged on the second connector body, and the inner wall of the second insertion slot is provided with an internal thread, and the second pipeline is provided with an external thread adapted to the internal thread;

[0021] The second bolt hole is arranged on the second connector body and is adapted to the fastener;

[0022] Among them, the second bolt hole is arranged with multiple, and the position corresponds to the first bolt hole.

[0023] The second adapter body provides a mounting base for the second insertion slot and the second bolt hole, and the shape thereof is adapted to the first adapter body. The second insertion slot is formed in the second adapter body, and an inner thread is arranged on the inner wall of the second insertion slot. An outer thread adapted to the inner thread is arranged on the second pipeline. The second pipeline is quickly connected and accurately positioned with the second adapter body through cooperation of the inner thread and the outer thread. During installation, the second pipeline can be accurately fixed in the second adapter body by screwing the outer thread of the second pipeline into the inner thread of the second insertion slot, thereby effectively improving the installation efficiency. Meanwhile, the threaded connection facilitates disassembly and maintenance. When the automobile air conditioner pipeline assembly needs to be overhauled or parts need to be replaced, the second pipeline can be conveniently disassembled from the second adapter body, thereby reducing the difficulty and cost of maintenance.

[0024] Meanwhile, the plurality of second bolt holes correspond to the first bolt holes, and the first adapter body and the second adapter body are tightly connected together through fasteners. The multi-point connection mode can uniformly disperse the connection force, thereby enhancing the overall stability and load capacity of the adapter mechanism and ensuring that the two pipelines will not be loosened or separated in a complex working environment.

[0025] Further, the fastener comprises a force applying portion, a first threaded segment, a smooth portion and a second threaded segment connected in sequence. The first threaded segment is adapted to the first bolt hole, and the second threaded segment is adapted to the second bolt hole.

[0026] The staff can apply torque to the force applying portion to screw the fastener into the first bolt hole and the second bolt hole, thereby realizing connection of the first adapter body and the second adapter body. The adaptability of the first threaded segment to the first bolt hole ensures that the fastener can be accurately screwed into the first bolt hole of the first adapter body. The first threaded segment and the second threaded segment are threadedly connected with the first bolt hole and the second bolt hole, thereby generating a certain pre-tightening force, so that the spacing between the first adapter body and the second adapter body is reduced, the first sealing ring and the second sealing ring between the first adapter body and the second adapter body are pressed, and the sealing performance of the connection is improved, thereby preventing refrigerant leakage.

[0027] Further, the first pipeline is provided with a sealing joint. The sealing joint comprises a contact portion and an insertion portion. A limiting groove in contact with the contact portion is arranged in the second insertion slot. The outer wall of the insertion portion is in contact with the inner wall of the second pipeline.

[0028] The sealing function is installed on the sealing joint, thereby improving the sealing effect between the first pipeline and the second pipeline and reducing the risk of refrigerant leakage. The sealing joint comprises a contact portion and an insertion portion. The contact portion is in contact with the limiting groove in the second insertion slot, thereby playing a role in positioning and supporting. During installation, the contact portion can be embedded in the limiting groove, thereby ensuring the accurate relative position of the sealing joint and the second adapter body, preventing displacement of the sealing joint during installation and use, and ensuring the stability of the sealing.

[0029] When the contact portion is in contact with the limiting groove, the contact surfaces of the two can form a sealing surface, filling the gap between the first and second connecting bodies, reducing the channel for refrigerant leakage, and preventing refrigerant from leaking from the contact portion.

[0030] Further, the outer wall of the contact portion is sleeved with a first sealing ring, which is in contact with the limiting groove and is extruded between the limiting groove and the sealing joint.

[0031] The installation of the first sealing ring further improves the sealing performance between the contact portion and the limiting groove. When the first sealing ring is extruded between the limiting groove and the sealing joint, it can fill the small gap between the two and form a sealing barrier, effectively preventing refrigerant from leaking from the contact portion. At the same time, the first sealing ring has a certain elasticity and can play a buffering role during installation and use, reducing damage to the sealing joint and the limiting groove caused by installation errors or vibration and the like.

[0032] Further, a second sealing ring is further provided between the first and second connecting bodies.

[0033] The installation of the second sealing ring can provide additional sealing protection for the connection between the first and second connecting bodies, further improving the sealing performance of the entire automobile air conditioning pipeline assembly. In cooperation with the first sealing ring, double sealing can greatly reduce the risk of refrigerant leakage and improve the refrigeration efficiency and reliability of the air conditioning system.

[0034] The beneficial effects of the present application are:

[0035] 1. The automobile air conditioning pipeline assembly of the present application sets the butt joint mechanism, embeds the first pipeline in the first connecting piece, embeds the second pipeline in the second connecting piece, and connects the two connecting pieces by the fastener to communicate the two pipelines, which can more effectively ensure the sealing performance of the connection, solving the problem of poor sealing effect of the existing connection mode.

[0036] 2. Through the cooperation of the first connecting piece, the second connecting piece and the fastener, the installation method is also more simple and fast, and it is convenient for subsequent workers to regularly disassemble and protect the butt joint mechanism or replace and maintain the pipeline.

[0037] 3. The thread cooperation of the first threaded section, the second threaded section and the first bolt hole and the second bolt hole can generate a certain pre-tightening force, so as to make the distance between the first connecting piece and the second connecting piece smaller, extrude the first sealing ring and the second sealing ring between the two, and improve the sealing performance of the connection to prevent refrigerant leakage.
