[0002] As an important part of vehicle comfort, the reliability and sealing of the pipe connection of the automobile air conditioner system directly affect the working efficiency and stability of the system. The traditional automobile air conditioner pipe is mostly assembled by scattered metal pipes or hoses through flanges, clamps and other connecting parts. This connection method has the following defects:

[0003] 1. Loose structure, large space occupation: The traditional pipe layout needs multiple independent connecting parts and supporting structures, which leads to complex pipe layout in the engine compartment, large space occupation, and is not conducive to compact design, especially in new energy vehicles where space is more limited.

[0004] 2. Low assembly efficiency: The scattered pipes need to be installed and fixed section by section, the assembly process is complicated, and the pipe layout needs to be adjusted repeatedly to ensure the sealing, which increases the labor cost of the production line.

[0005] 3. Poor shock resistance and sealing: The vibration during vehicle driving easily causes the pipe joint to loosen, and the risk of refrigerant leakage is high.

[0006] 4. Inconvenient maintenance and detection: The pipe system lacks integrated detection interface, and it is difficult to monitor the pressure, temperature and other parameters of the refrigerant in real time, and when troubleshooting, multiple pipes need to be disassembled, which increases the maintenance cost.

DETAILED DESCRIPTION

[0057] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0058] Embodiment 1

[0059] Please refer toFigure 1 、 Figure 2 、 Figures 4-8 The automobile air conditioner pipeline pressing plate assembly comprises two sets of matched and spliced pressing plate structures 1, and the two sets of pressing plate structures 1 are both provided with a connecting channel 11, a connecting inlet 12 and a connecting outlet 13 arranged in the same plane.

[0060] The automobile air conditioner pipeline pressing plate assembly further comprises a connecting assembly 2 assembled to the connecting inlet 12 and the connecting outlet 13, and the connecting assembly 2 comprises a mounting sleeve 21, an expansion tube 22, a positioning gland 23 and an adjusting knob 24. The mounting sleeve 21 is inserted into the connecting inlet 12 or the connecting outlet 13, the expansion tube 22 is slidably inserted into the mounting sleeve 21 and is rotatably connected to the adjusting knob 24, the positioning gland 23 is sleeved to the outer periphery of the mounting sleeve 21 and is rotatably connected to the outer side of the connecting inlet 12 or the connecting outlet 13, and the adjusting knob 24 comprises a rotating disc 241 and an operating part 242. The rotating disc 241 is rotatably connected to the shaft of the positioning gland 23 and abuts against the outer side of the mounting sleeve 21, and the operating part 242 extends to the outer side of the positioning gland 23. The outer side of the expansion tube 22 is fixedly connected with an assembled pipe 221 arranged on the outer side of the adjusting knob 24, and the outer wall of the assembled pipe 221 is provided with a plurality of annular protrusions 222 arranged in the axial direction.

[0061] The two sets of pressing plate structures 1 are both made of alloy material and are processed by drilling. The two sets of pressing plate structures 1 are designed as special-shaped flat plate structures, are assembled into an integrated structure by matched splicing and are fixed to the frame of the automobile engine compartment. The two sets of pressing plate structures 1 have the advantages of compact structure and convenient disassembly and assembly.

[0062] The two sets of pressing plate structures 1 are used as pipeline connecting pieces of high-pressure sides and low-pressure sides. For the pressing plate structure 1 applied to the high-pressure side, the connecting inlet 12 is used for connecting the pipeline led out from the compressor exhaust port, and the connecting outlet 13 is used for connecting the pipeline led out from the condenser inlet. The high-pressure gaseous refrigerant pressurized by the compressor is introduced into the connecting inlet 12, is transmitted through the corresponding connecting channel 11 and is delivered to the condenser from the connecting outlet 13.

[0063] For the pressing plate structure 1 applied to the low-pressure side, the connecting inlet 12 is used for connecting the pipeline led out from the evaporator outlet, and the connecting outlet 13 is used for connecting the pipeline led out from the compressor suction port. The low-pressure gaseous refrigerant in the evaporator is introduced into the connecting inlet 12, is transmitted through the corresponding connecting channel 11 and is delivered to the compressor from the connecting outlet 13.

[0064] Since there is a temperature difference between the refrigerants transmitted by the two sets of pressing plate structures 1, in order to avoid heat conduction through the pressing plate structure 1, heat insulation material can be laid at the connecting and abutting parts of the two sets of pressing plate structures 1.

[0065] For the connection assembly 2, the mounting sleeve 21 is nested and inserted into the connection inlet 12 or the connection outlet 13, and is stably assembled by the positioning gland 23 together with the rotating disc 241 in the rotationally mounted adjusting knob 24. The telescopic tube 22 arranged inside is in sliding insertion with the mounting sleeve 21 and is rotationally connected with the adjusting knob 24. By twisting the operation part 242 of the adjusting knob 24, the telescopic tube 22 can be driven to be telescoped along the axial direction of the mounting sleeve 21, thereby realizing the adjustment and correction of the air conditioner pipeline assembly stage, so as to ensure that the connection passage 11 can be stably connected with the corresponding parts of the pressing plate structure 1 and the air conditioner.

[0066] The assembly connecting tube 221 and the annular protrusion 222 arranged at the outer side end of the telescopic tube 22 can be stably connected with the connection passage 11, effectively avoiding the connection passage 11 from falling off the pressing plate structure 1 due to the vibration of the automobile driving or the air conditioner running.

[0067] The outer wall of the positioning gland 23 is provided with a hexagonal seat, so as to facilitate the screwing operation of the positioning gland 23, thereby realizing the quick installation of the positioning gland 23 on the pressing plate structure 1.

[0068] Embodiment 2

[0069] Please refer to Figures 1-9 In order to facilitate the filtering of the refrigerant transmitted in the connection passage 11, so as to avoid the impurities carried in the refrigerant from entering the pipeline of the condenser and causing blockage, and to facilitate the cleaning of the intercepted impurities, the following technical scheme is provided.

[0070] The connection passage 11 is coaxially arranged with the connection inlet 12, and the connection passage 11 is perpendicularly arranged with the connection outlet 13. One set of the pressing plate structure 1 is further provided with a foreign matter discharging interface 14 arranged near the side close to the connection outlet 13. The foreign matter discharging interface 14 is coaxially and communicatively arranged with the connection passage 11. The foreign matter discharging interface 14 is screwed with a sealing cover 141. The pressing plate structure 1 provided with the foreign matter discharging interface 14 is further assembled with a filter element 131. The filter element 131 is assembled into the connection outlet 13.

[0071] The pressing plate structure 1 for high-pressure side pipeline connection is provided with the foreign matter discharging interface 14 and the filter element 131. The filter element 131 is tightly positioned by the mounting sleeve 21 in the connection assembly 2 at the position of the connection outlet 13, which can effectively filter and intercept the impurities contained in the high-pressure gaseous refrigerant output by the compressor. The intercepted impurities will be gathered at the downstream end of the connection passage 11 (the position where the foreign matter discharging interface 14 and the sealing cover 141 are arranged). When it is necessary to clean the impurities, the sealing cover 141 is unscrewed. The outer wall of the sealing cover 141 is also provided with a hexagonal seat, so as to facilitate the screwing operation.

[0072] For the convenience of real-time detection of the pressure and temperature of the refrigerant transmitted in the connecting passage 11, and further realizing the detection of the running state of the air conditioner, the following technical scheme is provided.

[0073] The detection interface 15 is vertically arranged with the connecting passage 11, and the connecting outlet 13 and the detection interface 15 are arranged on the same side. The temperature and pressure integrated sensor 151 is arranged in the detection interface 15.

[0074] The temperature and pressure integrated sensor 151 is also arranged in the detection interface 15 by screwing, so a hexagonal seat is arranged on the outer side of the temperature and pressure integrated sensor 151 to facilitate screwing operation. The temperature and pressure integrated sensor 151 can detect the temperature and pressure of the refrigerant transmitted in the connecting passage 11.

[0075] The pipelines and interfaces arranged in the pressing plate structure 1 are arranged on the same plane, which can improve the compactness of the arrangement and facilitate the drilling processing of the pipelines and interfaces. The detection interface 15 and the connecting outlet 13 are arranged on the same side of the pressing plate structure 1, so that the other side of the pressing plate structure 1 is left empty to facilitate the nested combination of the two groups of pressing plate structures 1.

[0076] To ensure that the two groups of pressing plate structures 1 can be stably nested and combined, and to facilitate the rapid and stable installation of the two groups of pressing plate structures 1 on the frame structure of the automobile, the following technical scheme is provided.

[0077] The assembly pad 16 is fixedly connected to the side wall of the two groups of pressing plate structures 1. The assembly through hole 161 is arranged at the center position of the assembly pad 16. The assembly pin rod 162 and the assembly pin hole 163 are arranged on the assembly pad 16 and are arranged on both sides of the assembly through hole 161, respectively.

[0078] When the two groups of pressing plate structures 1 are nested and combined, the assembly through holes 161 arranged in the two groups of pressing plate structures 1 are coaxially butted. The assembly pin rod 162 arranged on one group of pressing plate structures 1 is nested and inserted into the assembly pin hole 163 arranged on the other group of pressing plate structures 1.

[0079] The thickness of the assembly pad 16 is slightly smaller than 1 / 2 of the thickness of the pressing plate structure 1, so that the two groups of pressing plate structures 1 are nested and assembled and the thermal insulation material is added, and the two groups of pressing plate structures 1 are in the flush state. The two groups of pressing plate structures 1 are arranged symmetrically. At this time, the two assembly pads 16 are in the splicing state. Through the cooperation of the assembly pin rod 162 and the assembly pin hole 163, the displacement of the pressing plate structure 1 perpendicular to the direction of the assembly pin rod 162 can be limited. By penetrating the two assembly through holes 161 with a single bolt assembly and then fixedly installing it on the frame structure, the rapid assembly of the two groups of pressing plate structures 1 can be realized.

[0080] Embodiment 3

[0081] Please refer to Figures 1-9 To ensure that the mounting sleeve 21 can be fixedly installed in the pressure plate structure 1 and limited from invalid rotation, and to ensure that the positioning gland 23 can be stably screwed on the pressure plate structure 1, the following technical solutions are provided.

[0082] The pressure plate structure 1 is further fixedly connected with an assembly sleeve 17 arranged at the outer side end of the connection inlet 12 and the connection outlet 13. The inner side of the assembly sleeve 17 is provided with a positioning groove 171, and the outer side end of the mounting sleeve 21 is fixedly connected with a positioning block 211 which is nested and matched with the positioning groove 171. The positioning gland 23 is screwed onto the outer side wall of the assembly sleeve 17.

[0083] The assembly sleeve 17 can ensure that the positioning gland 23 is stably screwed thereon. The inner side positioning groove 171 can also ensure that the mounting sleeve 21 with the positioning block 211 is stably inserted therein to limit invalid rotation.

[0084] To ensure the sealing effect of the mounting sleeve 21 assembled in the connection inlet 12 and the connection outlet 13, to ensure that the telescopic pipe 22 stably slides in the mounting sleeve 21 and to ensure the sealing effect of the telescopic pipe 22 connected with the mounting sleeve 21, the following technical solutions are provided.

[0085] The outer wall of the telescopic pipe 22 is provided with a guide groove 223, and the outer side end of the mounting sleeve 21 is provided with a guide protrusion 212 which is slidably inserted into the guide groove 223. The inner side end of the mounting sleeve 21 and the telescopic pipe 22 are respectively fixedly connected with an outer limiting ring 213 and an inner limiting ring 224. The outer side of the outer limiting ring 213 is arranged with a sealing rubber ring 214. The telescopic pipe 22 is peripherally sleeved with a sealing rubber sleeve 225 arranged inside the mounting sleeve 21. The two ends of the sealing rubber sleeve 225 abut against the inner limiting ring 224 and the outer side end of the mounting sleeve. The cross section of the sealing rubber sleeve 225 is provided with a corrugated structure.

[0086] The arrangement of the guide groove 223 and the guide protrusion 212 can realize the stable installation of the telescopic pipe 22 in the mounting sleeve 21 in a relative sliding manner, while not affecting the arrangement of the thread groove on the outer wall of the telescopic pipe 22.

[0087] After the mounting sleeve is assembled into the connection inlet 12 and the connection outlet 13, the sealing rubber ring 214 abuts against the inner side end of the outer limiting ring 213, the connection inlet 12 or the connection outlet 13 to realize the sealing installation of the mounting sleeve. For the connection outlet 13 assembled with the filter element 131, the corresponding sealing rubber ring 214 abuts against the outer edge of the filter element 131.

[0088] The sealing sleeve 225 with corrugated structure design can ensure that the telescopic tube 22 is in sealing contact with the mounting sleeve 21 in any telescopic posture, thereby avoiding leakage of refrigerant from the gap between the mounting sleeve 21 and the telescopic tube 22.

[0089] The telescopic movement of the telescopic tube 22 can compress or loosen the sealing sleeve 225, but the inflection point position of the corrugated structure on the sealing sleeve 225 can always be in sealing contact with the inner wall of the mounting sleeve 21 or the outer wall of the telescopic tube 22, thereby effectively preventing leakage of refrigerant.

[0092] The rotating mechanism 4 comprises an assembly disc 41, and the clamping mechanism 6 comprises an adjusting disc 61, a chuck 62, a clamping plate 63, and an adjusting motor 64. The adjusting disc 61 is rotatably installed in the assembly disc 41 and is in power connection with the adjusting motor 64. The chuck 62 and the clamping plate 63 are arranged on the two sides of the adjusting disc 61, respectively. The chuck 62 and the clamping plate 63 each comprise a plurality of groups that slide radially into the assembly disc 41. The chuck 62 and the clamping plate 63 are respectively fixedly connected with a guide pin shaft A621 and a guide pin shaft B631. The two sides of the adjusting disc 61 are respectively provided with an arc-shaped guide groove A611 and an arc-shaped guide groove B612. The arc-shaped guide groove A611 and the arc-shaped guide groove B612 are respectively in nested combination with the guide pin shaft A621 and the guide pin shaft B631. The chuck 62 is used for clamping and fixing the positioning gland 23 or the operating part 242. The clamping plate 63 is used for pressing and assembling the pipeline connected to the assembly connecting pipe 221.

[0093] A clearance opening is formed at the center of the assembly disc 41 and the adjusting disc 61 to ensure that the connected pipeline and the connecting assembly 2 can be arranged at the center without spatial interference. The chuck 62 is arranged in the radial direction of the adjusting disc 61. When the adjusting disc 61 operates, the chuck 62 can be driven by the arc-shaped guide groove A611 to perform synchronous telescopic movement, thereby clamping and fixing the hexagonal seat on the outer side of the positioning gland 23 or the operating part 242 of the adjusting knob 24, realizing the assembly operation of the connecting assembly 2 to the pressing plate structure 1 and the adjustment and correction of the position and posture of the telescopic tube 22 and the assembly connecting pipe 221. The chuck 62 can also clamp and fix the sealing cover 141 and the temperature and pressure integrated sensor 151 for assembly operation.

[0094] The clamping plates 63 are arranged along the axial direction of the adjusting disc 61 to ensure that they can slide along the radial direction of the adjusting disc 61 for adjustment. Therefore, a guide plate 632 is fixedly connected to the clamping plate 63 and slidingly inserted into the assembly disc 41. A guide pin shaft B631 is fixedly connected to the guide plate 632B. By controlling the rotation of the adjusting disc 61, each group of clamping plates 63 can be synchronously extended and retracted to effectively clamp and press the connecting pipeline to the assembly pipe 221.

[0095] An arc-shaped pressing groove 633 is arranged on the clamping plate 63 and matched with the annular protrusion 222. The arc-shaped pressing groove 633 is used to press the end of the connecting pipeline to the annular protrusion 222 outside the assembly pipe 221 to realize the sealed connection between the connecting pipeline and the assembly pipe 221.

[0096] When the adjusting disc 61 is adjusted in the forward direction, each group of clamping heads 62 can be controlled to synchronously extend (clamp) while the clamping plates 63 are controlled to synchronously retract (cancel clamping). When the adjusting disc 61 is adjusted in the reverse direction, each group of clamping heads 62 can be controlled to synchronously retract (cancel clamping) while the clamping plates 63 are controlled to synchronously extend (clamp) to realize the selective use of the clamping heads 62 and the clamping plates 63.

[0097] The rotating mechanism 4 is driven by the driving mechanism 5 to operate synchronously with the clamping mechanism 6. The clamping heads 62 can drive the sealing cover 141, the temperature and pressure integrated sensor 151, the positioning gland 23, and the operation part 242 of the adjusting knob 24 to rotate. The clamping heads 62 can press the connecting pipeline on the annular protrusion 222 and deform. During the rotation, the deformation forms an annular structure to realize the sealed connection of the connecting pipeline on the assembly pipe 221.

[0098] When the sealing cover 141, the temperature and pressure integrated sensor 151, and the positioning gland 23 are screwed and assembled, the corresponding parts also have axial movement. Therefore, the axial displacement provided by the feeding mechanism 3 can meet the axial movement requirement of the assembled parts.

[0099] Embodiment 5

[0100] Please refer to Figure 10 To ensure that the feeding mechanism 3 can drive the assembled parts to realize stable axial feeding, ensure that the rotating mechanism 4 can be stably assembled and operated on the feeding mechanism 3, and ensure that the adjusting motor 64 can drive the adjusting disc 61 to stably operate, the following technical solutions are provided.

[0101] The feeding mechanism 3 includes an assembly support 31, a threaded sleeve 32, and guide rods 33 and threaded rods 34 which are fixedly installed in parallel. The threaded sleeve 32 is rotationally installed on the assembly support 31 and rotationally connected with the threaded rods 34. The assembly support 31 is slidingly inserted with the guide rods 33. The assembly disc 41 is rotationally installed on the assembly support 31.

[0102] The adjusting motor 64 is fixedly installed on the assembling disc 41, the outer edge of the adjusting disc 61 is fixedly connected with a worm wheel 613, and the output shaft of the adjusting motor 64 is fixedly connected with a worm 641 which is rotatably installed in the assembling disc 41, and the worm 641 is matched with the worm wheel 613.

[0103] The guide rod 33 can ensure the stable axial sliding of the assembling support 31 and the components assembled thereon, and the cooperation between the control threaded sleeve 32 and the threaded rod 34 can ensure the effective feeding of the assembling support 31 and the components assembled thereon during the assembling operation.

[0104] The assembling disc 41 is rotatably installed on the assembling support 31, and can drive the clamping mechanism 6 assembled thereon to synchronously and stably operate when the assembling disc 41 operates. The adjusting motor 64 drives the adjusting disc 61 to stably operate through the combination of the worm 641 and the worm wheel 613. Since the combination of the worm 641 and the worm wheel 613 has the characteristics of speed reduction, torque increase and one-way self-locking, the chuck 62 and the clamping plate 63 can effectively clamp the corresponding components. After the posture adjustment is completed, the worm 641 can effectively lock the worm wheel 613 and the adjusting disc 61, thereby ensuring that the chuck 62 or the clamping plate 63 continuously and stably clamps the corresponding components.

[0105] Embodiment 6

[0106] Please refer to Figure 10 、 Figure 14 、 Figure 15 In order to ensure that the driving mechanism 5 can be stably assembled on the assembling support 31 and continuously provide power to the rotating mechanism 4 while selectively providing power to the feeding assembly, the following technical solutions are provided.

[0107] The driving mechanism 5 comprises a driving motor 51, a transmission shaft 52 and a clutch assembly 53. The driving motor 51 is fixedly installed on the assembling support 31, and the transmission shaft 52 is rotatably installed on the assembling support 31 and is in power connection with the driving motor 51. The feeding mechanism 3 further comprises a reversing bevel gear A35 fixedly connected to the threaded sleeve 32, and the rotating mechanism 4 further comprises a reversing bevel gear B42 fixedly connected to the assembling disc 41. The clutch assembly 53 is in power connection with the transmission shaft 52 and the reversing bevel gear A35, and the transmission shaft 52 is fixedly connected with a reversing bevel gear b521 which is in meshing with the reversing bevel gear B42.

[0108] The output shaft of the driving motor 51 is fixedly connected with a driving bevel gear 511, and the transmission shaft 52 is fixedly connected with a transmission bevel gear 522 which is in meshing with the driving bevel gear 511. When the driving motor 51 operates, the transmission shaft 52 can be driven to stably operate through the combination of the driving bevel gear 511 and the transmission bevel gear 522, and the transmission shaft 52 can drive the assembling disc 41 and the clamping mechanism 6 assembled therein to stably operate at all times through the combination of the reversing bevel gear b521 and the reversing bevel gear B42.

[0109] The clutch assembly 53 can realize the power connection or cut-off of the transmission shaft 52 and the reversing bevel gear A 35 as required, thereby controlling the selective operation of the feeding mechanism 3.

[0110] In order to ensure that the clutch assembly 53 can realize the power connection or cut-off adjustment, the following technical solutions are provided.

[0111] The clutch assembly 53 comprises end face gears A 531 and B 532 kept in meshing nested state, a spline shaft 533, a ring-shaped permanent magnet 534, a ring-shaped electromagnet 535, a supporting spring 536, and a reversing bevel gear a 537. The end face gears A 531 and the reversing bevel gear a 537 are kept coaxially fixed and rotationally installed on the assembly support 31, the reversing bevel gear A 35 is kept in meshing with the reversing bevel gear a 537, the spline shaft 533 is slidingly inserted into the transmission shaft 52 and kept coaxially fixed with the end face gear B 532, the ring-shaped permanent magnet 534 is fixedly installed on the end face gear B 532, the ring-shaped electromagnet 535 is fixedly installed on the assembly support 31 and kept coaxially arranged with the ring-shaped permanent magnet 534, and the supporting spring 536 is sleeved on the outer periphery of the spline shaft 533 and kept in abutment with the end face gear B 532 and the transmission shaft 52 at both ends.

[0112] Since the spline shaft 533 is kept slidingly inserted into the transmission shaft 52, the end face gear B 532 can always stably receive the power of the transmission shaft 52 during the lifting movement, the current direction of the ring-shaped electromagnet 535 can be controlled to adjust the attraction or repulsion of the ring-shaped permanent magnet 534. When the attraction is generated, the end face gear B 532 can be driven to move downward and separate from the end face gear A 531 to cut off the power, against the resistance of the supporting spring 536.

[0113] When the repulsion is generated, the end face gear B 532 can be jointly acted on by the supporting spring 536 to be lifted upward and meshed with the end face gear A 531, thereby stably transmitting the power of the transmission shaft 52 to the reversing bevel gear a 537 through the spline shaft 533, the end face gear B 532, and the end face gear A 531, and stably driving the reversing bevel gear A 35 and the threaded sleeve 32 by the reversing bevel gear a, to realize the stable operation of the feeding mechanism 3.
