Description

Technical Field

[0001] The present disclosure relates to a block-type fitting for a fluid line system in a motor vehicle. In particular, the present disclosure relates to a block-type fitting having a sealing component for forming a fluid-tight connection in a motor vehicle. Background Art

[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] Connecting devices are commonly used in fluid line assemblies in motor vehicles including electric vehicles (EV) and hybrid vehicles. In particular, connecting devices are used in air-conditioning systems, cooling systems (such as coolant circuits), valve units and pump units. In limited space, the design must be particularly compact and lightweight, and the pipe connector or pipe connector in the air-conditioning system may also include metal, rubber and plastic materials. In addition, the pipeline or pipe is attached by means of a block assembler including an adapter, and the block assembler is provided with a sealing element. Therefore, it is necessary to firmly and permanently seal the block assembler and / or the adapter to the pipeline, and the block assembler and / or the adapter are detachably connected to another pipeline or connected to another component in the air-conditioning system. However, in addition to high pressure and temperature, vibrations will also occur and transmit vibrations in the components of the air-conditioning system. Therefore, the connecting device used in the air-conditioning system must be constructed in such a way that despite the presence of vibrations, corrosive media, high temperature and high pressure, the connecting device can still provide a lasting connection, and fluid leakage will not occur.

[0004] For example, a vehicle air conditioning system contains one of various environmentally acceptable refrigerants (e.g., CO2 (R-744) or a fluorinated hydrocarbon). One of the concerns about the release of refrigerant into the atmosphere has led to regulations requiring that the refrigeration system operate essentially without leakage. In addition, another concern about the release of refrigerant into the system has led to failure of the air conditioning system due to leakage. The tubes that make up the pipelines in these systems can be connected to each other at certain connections using block assemblers and / or adapters as described above. In order to connect the relative tubes, each tube is attached to a corresponding element of the block assembler including the adapter, and the two blocks are then connected to each other. The joint is sealed by at least one sealing member of a deformable metal or other suitable material. Typically, a vehicle air conditioning system includes components from multiple sources assembled by an OEM. Typically, a block of the block assembler is integral with a major system component such as a compressor or condenser and a mating assembly element portion of a line group. Modern assembly procedures require simplified component delivery and handling.

[0005] Furthermore, it is important that fluid line systems in vehicles, such as air conditioning systems, are constructed to be lightweight and also durable in a limited space. However, it has been found that the number of fastening devices that secure the components of the fluid line system together is limited, and it is also difficult to configure a block assembler and / or adapter for providing a durable seal of the connection device, which is used to form a secure connection (i.e., a fluid-tight connection) in the fluid line system. In order to effectively arrange sealed and secure fluid lines in vehicles, a plurality of devices and methods including connection devices of block assemblers are continuously developed and used for various fluid line systems.

[0010] According to further aspects of the present disclosure, in an assembled configuration, the first outlet of the adapter body is inserted into the first hole of the main block to connect the first hole of the main block with the channel of the adapter body to define a fluid passage along the longitudinal axis. The adapter protrusion of the adapter body is positioned in the inwardly directed step of the main block so that the first surface of the adapter protrusion faces the stepped annular surface of the main block in a manner substantially parallel to the stepped annular surface of the main block.

[0011] According to further aspects of the present disclosure, the main block is securely coupled with the fitting body and the mating block using a fastening member inserted through a second mating hole formed in the mating block and tightened in the second hole formed in the main block.

[0023] The following description is merely exemplary in nature and is in no way intended to limit the present disclosure or its application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate the same or corresponding parts and features.

[0024] Figure 1 A side view of a block assembly 10 connected to a pipe or hose is shown, and Figure 2 An exploded view of the block assembly 10 is shown. As illustrated, the block assembly 10 includes a main block 100, a mating block 200, an adapter body 250, and a sealing gasket 300, which are connected together to form an assembled configuration and also define boundary surfaces as a whole, which are formed in a facing relationship to form a fluid-tight connection of the tubes 12 and 14 aligned along the longitudinal axis X. Figure 1 and Figure 2 Although illustrated as connecting spaced-apart tube segments 12 and 14 as an exemplary embodiment of the present disclosure, the block assembly 10 may connect one of the tubes 12 or 14 to a system component such as a compressor or evaporator or other element (not shown).

[0025] Figure 3 A cross-sectional view of the block assembly 10 connected to tubes 12 and 14 is shown. Figures 1 to 3 As shown, the main block 100 includes a first hole 102 and a second hole 104, each of which is substantially circular in cross-section and extends through the thickness of the main block 100. The first hole 102 defines a fluid passage through the main block 100, and the second hole 104 is configured to receive a fastening member 16, as will be described below. According to other forms of the present disclosure, the first hole 102 and the second hole 104 may also be formed to be asymmetrical, non-circular, or have radial protrusions. The main block 100 includes a first orifice 106 and a second orifice 108 that are connected to each other through the first hole 102. In addition, for example, the main block 100 may be a part or component of a fluid pipeline system in a vehicle. In addition, as Figures 1 to 3 As shown, the first aperture 106 formed in a substantially circular shape extends from the flat outer end surface 110 to receive the first tube 12 , so that the first tube 12 is inserted into the first aperture 106 and securely connected to the main block 100 in a firmly bonded manner.

[0026] In addition, the second aperture 108 formed on the flat inner end surface 112 includes an inwardly directed step 114 that defines a stepped annular surface 116 for receiving the adapter body 250. Figure 3 As shown, the stepped annular surface 116 of the second aperture 108 is formed radially around the first hole 102 relative to the longitudinal axis X. In addition, the stepped annular surface 116 has a diameter dimension D a , the diameter dimension D a Greater than the diameter D of the first hole 102 b .

[0027] exist Figure 2 and Figure 3 , the adapter body 250 has a channel 252 which is formed in a straight shape as a fluid passage along the longitudinal axis X. When the main block 100 and the adapter body 250 are connected together, the first hole 102 of the main block 100 is aligned with and communicated with the channel 252 of the adapter body 250 to define a fluid passage along the longitudinal axis. Figure 2 As shown, the adapter body 250 includes at least two outlets, such as a first outlet 254 and a second outlet 256 formed at both ends of the adapter body 250, such that the first outlet 254 is in communication with the second outlet 256 through the channel 252. Figure 3 In the embodiment, the first outlet 254 of the adapter body 250 is inserted into the first hole 102 of the main block 100, so that the channel 252 formed in the adapter body 250 communicates with the first hole 102 of the main block 100, thereby defining a fluid passage. The second outlet 256 is usually connected to the second pipe or hose 14 to form a secure connection (i.e., a fluid-tight connection) in the fluid pipeline system.

[0028] In addition, if Figure 2-Figure 3 As shown, the second outlet 256 of the adapter body 250 receives the second tube 14 to be connected by a firmly bonded manner, in particular by laser welding, spin welding and other adhesive materials, so that the second tube 14 is inserted into the second outlet 256 and firmly connected to the adapter body 250. Although the first opening and the second opening formed in the adapter body 250 are both labeled as "outlets", those skilled in the art will recognize that one or both openings can be regarded as "inlets", so for simplicity, each of the openings 254 and 256 of the adapter body 250 will be referred to as an outlet in this article, but can also be regarded as an inlet according to the selected arrangement in the block assembly device 10.

[0029] exist Figure 2, the first outlet 254 has a first end 253 and a second end 255 extending from the first end 253 along the longitudinal axis X. In addition, the adapter body 250 includes an adapter protrusion 258 that is formed radially and outwardly around the first end 253 of the first outlet 254. Figure 2 and Figure 3 As shown, the adapter protrusion 258 has a first surface 257 that faces the stepped annular surface 116 of the primary block 100 and a second surface 259 that faces the inner surface 206 of the mating block 200 in the assembled configuration of the block assembly device 10 .

[0030] The adapter body 250 is formed of a polymer material, such as polyamide (PA) and PPA, PPS, etc., and polyamide (PA) is, for example, polyamide 612 (PA 612), PA 6, PA 12. In addition, in order to improve strength and / or mechanical stability, the plastic material can be provided with a fiber-reinforced material such as glass fiber, so that the adapter body 250 is formed of a pressure-resistant plastic material. In addition, a resin-based plastic material can also be provided. The resin-based plastic material forms a hard glass-like component, which is firmly cross-linked in three dimensions by means of chemical bonds. This type of material has high thermomechanical strength and low density.

[0031] In addition, if Figure 3As shown, the second tube 14 combined with the adapter body 250 in the block-type assembly device 10 is also made of a plastic material, which is selected from a material that can be connected or welded to the adapter body 250, such as polyamide (PA). In addition, the adapter body 250 of the block-type assembly device 10 is generally combined with a multi-layer tube having an outer layer (or inner layer) material, and the adapter body 250 is compatible with the outer layer (or inner layer) material in terms of welding (such as laser welding or spin welding). However, even if polyamide (PA) is used for the adapter body 250 and the tube, each polyamide (PA) material used in these two parts can be different. In the fluid pipeline system, the tube can be a single-layer or multi-layer tube, and the tube is generally made of polyamide (PA 6, PA 12, PA612, semi-aromatic polyamide (PA9T), HDPE, PP, etc.), which can be welded to the adapter body. However, the adapter body is generally made of PA12 (with up to 30% glass fiber reinforcement), PPA (polyphthalamide) or PP (polypropylene). This results in comparable mechanical and chemical properties. The block assembly device of the present disclosure is shown in combination with a fluid pipeline system in a motor vehicle, such as an air conditioning system or a cooling system, including an electric vehicle and a hybrid vehicle. As an example, the block assembly device 10 of the present disclosure is used in an air conditioning system having a compressor, a condenser, a heat exchanger, an evaporator, and an intermediate line connection. In particular, the block assembly device 10 is provided for an air conditioning system with a low weight, and is provided to have a durable and tight connection with the components of the air conditioning system in the vehicle (i.e., to suppress leakage in the component connection). However, the block assembly device 10 of the present disclosure is not limited and can also be used for other fluid pipeline systems, such as cooling systems (e.g., coolant circuits), valve units, pump units, etc. In addition, for example, the main block 100 can be a part or component of any fluid pipeline system (e.g., a refrigerant circuit or a coolant circuit) in a vehicle.

[0032] Reference again Figures 1 to 3 , the assembly block device 10 has a main block 100 and a mating block 200 configured to mate with each other. Similar to the main block 100, the mating block 200 includes a first mating hole 202 and a second mating hole 204, which have a substantially cylindrical cross-section extending through the thickness of the mating block 200. The second mating hole 204 is laterally spaced from the first mating hole 202, that is, spaced relative to the longitudinal axis X. In the assembled configuration of the block assembly device 10, as shown in FIG. Figure 3As shown, the first mating hole 202 of the mating block 200 and the first hole 102 of the main block 100 are aligned along the longitudinal axis X, so that the first mating hole 202 of the mating block 200 is firmly coupled with the adapter body 250. In addition, in the assembled configuration of the block assembly device 10, the second outlet 256 of the adapter body 250 is arranged inside the first mating hole 202 of the mating block 200, so that the second radial outer surface 260 of the second outlet 256 is coupled with the first mating hole 202 of the mating block 200. Figure 3 As shown, for example, the end of the second outlet 256 extends through the thickness of the mating block 200 to receive the second tube 14. In addition, in the assembled configuration of the block assembly device 10, the second surface 259 of the adapter protrusion 258 fully contacts the inner surface 206 of the mating block 200 and is also fully coupled to the inner surface 206 of the mating block 200.

[0033] exist Figure 3 In the block-type assembly device 10, the second hole 104 of the main block 100 and the second mating hole 204 of the mating block 200 are used to fix the main block 100 and the mating block 200 including the adapter body 250. In the assembled configuration of the block-type assembly device 10, the second hole 104 of the main block 100 is threaded to allow a fastening member 16 such as a screw to tightly hold the mating block 200 on the main block 100 (see Figure 1 ). In addition, the main block 100 and the mating block 200 are made of a metal material such as aluminum or a polymer material. In particular, the materials of the main block 100 and the mating block 200 are rigid and have a high stress capacity, so that the materials of the main block 100 and the mating block 200 suppress plastic deformation by limiting creep caused by the torque of the joint assembly.

[0034] exist Figure 2 and Figure 3 In the block assembly device 10, the sealing gasket 300 has a body portion 302, the body portion 302 is in the shape of a flat ring, and has a first plane surface 301 and a second plane surface 303. Figure 5 and Figure 6 The sealing gasket 300 further includes an inner sealing member 304 radially attached along the inner circumference of the body portion 302 and an outer sealing member 306 radially attached along the outer circumference of the body portion 302, so that the body portion 302 and the inner sealing member 304 and the outer sealing member 306 form a single unit.

[0035] exist Figure 6In the cross-sectional view of , the body portion 302 of the sealing gasket 300 is basically formed as an H-ring, and the body portion 302 has an inner radial groove 308 and an outer radial groove 310, and the inner radial groove 308 and the outer radial groove 310 are respectively used to receive the inner sealing member 304 and the outer sealing member 306. In addition, the body portion 302 of the sealing gasket 300 is made of a metal material such as aluminum or a polymer material such as PA 6, and the inner sealing member 304 and the outer sealing member 306 of the sealing gasket 300 are each formed of an elastomeric material such as rubber or an elastic material such as silicon. However, it can be understood that other sealing materials can be used as needed. The sealing gasket 300 having the material as described above is configured to reduce the penetration of system fluid between the main block 100 and the adapter body 250 in the assembled structure of the block assembly device 10.

[0036] like Figure 3 As shown, the sealing gasket 300 is placed in the space defined between the main block 100 and the adapter body 250 to seal the fluid passage of the block-type assembly device 10. In the assembled configuration of the block-type assembly device 10, the first planar surface 301 of the body portion 302 faces the stepped annular surface 116 of the main block 100, and the second planar surface 303 of the body portion 302 faces the first surface 257 of the adapter protrusion 258. Figure 3 and Figure 4 As shown, a first radial gap 18 is defined between the main block 100 and the sealing gasket 300, and a second radial gap 20 is defined between the adapter body 250 and the sealing gasket 300, and the first radial gap 18 and the second radial gap 20 are substantially perpendicular to the longitudinal direction of the block assembly device 10. In addition, as shown in FIG. Figure 3 As shown, in the assembled structure of the block assembly device 10, the inner sealing member 304 and the outer sealing member 306 are respectively in deformable contact with the main block 100 and the adapter body 250, so that the inner sealing member 304 and the outer sealing member 306 of the sealing gasket 300 are constructed to seal the fluid passage defined between the main block 100 and the adapter body 250 in the radial direction relative to the longitudinal axis X.

[0037] In addition, the outer diameter dimension D around the outer edge of the outer sealing member 306 is o Slightly larger than the diameter dimension D of the stepped annular surface 116 formed around the inwardly directed step 114 of the main block 100 a , and the inner diameter dimension D around the outer edge of the inner sealing member 304 i Slightly smaller than the diameter dimension D of the first radial outer surface 262 of the adapter body 250 rThus, in the assembled configuration of the block assembly 10, with the sealing gasket 300 radially disposed between the inner radial surface 118 of the main block 100 and the first radially outer surface 262 of the adapter body 250, the sealing gasket 300 is retained by frictional engagement between the main block 100 and the adapter body 250 in a radial direction relative to the longitudinal axis X.

[0038] Figure 4 Detailed cross-sectional views of the main block 100, the mating block 200, the adapter body 250 and the sealing gasket 300 are shown in the assembled configuration of the block assembly device 10. Figure 4 , the outer sealing member 306 of the sealing gasket 300 is deformably and frictionally engaged with the inner radial surface 118 of the inwardly directed step 114, so that the outer sealing member 306 is in sealing contact with the inner radial surface 118 of the main block 100 in the radial direction. In addition, the inner sealing member 304 of the sealing gasket 300 is deformably and frictionally engaged with the first radial outer surface 262 of the first outlet 254 formed in the adapter body 250, so that the inner sealing member 304 is in sealing contact with the first radial outer surface 262 of the adapter body 200 in the radial direction. Therefore, the sealing gasket 300 is frictionally and deformably held together with the main block 100 and the adapter body 250 in the radial direction relative to the longitudinal axis X, and the need for a torque-reliant sealing method along the longitudinal axis X (i.e., in the axial direction of the block assembly device 10) can be eliminated. In addition, as Figure 4 As shown, a sealing gasket 300 having an inner sealing member 304 and an outer sealing member 306 is disposed along the longitudinal axis X in the space defined between the main block 100 and the adapter body 250 to provide enhanced resistance to leakage of system fluid in the fluid passage formed within the block assembly 10 .

[0039] Reference again Figure 1 and Figure 2 In order to securely assemble the block assembly device 10, the main block 100, the adapter body 250 and the mating block 200 are connected using a fastening member 16 such as a screw, which is inserted through the second mating hole 204 of the mating block 200 and is securely tightened in the second hole 104 of the main block 100. When assembling the block assembly device 10, the sealing gasket 300 is radially arranged between the main block 100 and the adapter body 250 in the longitudinal direction of the block assembly device 10. In addition, the sealing gasket 300 having the inner sealing member 304 and the outer sealing member 306 is frictionally held between the inner radial surface 118 of the main block 100 and the first radial outer surface 262 of the adapter body 250 in the radial direction relative to the longitudinal axis X of the block assembly device 10. Once assembled, as shown in FIG. Figure 1 and Figure 3As shown, the main block 100 , the mating block 200 , and the fitting body 250 cooperate with the sealing gasket 300 to form a fluid-tight seal and inhibit leakage of fluid (liquid or gas) flowing out of the tubes 12 and 14 .

[0040] like Figure 4 and Figure 5 As shown, since the body portion 302 of the sealing gasket 300 is made of a metal material or a polymer material, the first plane surface 301 and the second plane surface 303 of the body portion 302 are configured to inhibit the system fluid from passing through the thickness of the body portion 302 as a permeation barrier. Due to the permeation barrier of the body portion 302, the cross-sectional area of ​​the elastomeric seal formed by the inner sealing member 304 and the outer sealing member 306 is reduced, so that the permeation area of ​​the system fluid in the sealing gasket 300 is also reduced. Therefore, the sealing gasket 300 used in the exemplary block assembly device 10 of the present disclosure is configured to improve the performance of the fluid-tight connection in the fluid pipeline system. As described above, in addition, due to the radial sealing of the inner sealing member 304 and the outer sealing member 306 formed in the sealing gasket 300, it also eliminates the need to rely on torque sealing along the longitudinal direction of the block assembly device 10 (i.e., the axial direction of the block assembly device), so that the sealing gasket 300 is configured to reduce the possibility of component creep in the assembly block device 10.

[0041] The block assembly device 10 according to an exemplary embodiment of the present disclosure is suitable for use in various fluid pipeline systems, such as air conditioning systems or cooling systems in motor vehicles including electric vehicles and hybrid vehicles. For example, the block assembly device 10 is suitable for use in cooling systems of hybrid vehicles or electric vehicles having cooling / thermostatic electronic components such as batteries and is also suitable for use in air conditioning systems. In addition, the fluid pipeline system used in the vehicle should be as lightweight as possible, but due to vibration and impact during vehicle operation, the fluid pipeline system also needs to provide a stable connection between components. Therefore, the block assembly device 10 of the present disclosure makes it possible to produce a lightweight, stable and durable connection.
