[0016] Compared with the prior art, the present invention provides a comprehensive air path detection device for vehicle suspension, which has the following beneficial effects:

[0017] 1. The present invention is provided with a measuring component, and the inner wall of the trachea is squeezed by the telescopic ramming rod, so that the inner wall of the trachea is squeezed and deformed. By setting up this component, when the trachea is in cold weather outdoors, the surface of the trachea will become brittle and more prone to external deformation problems.

By setting up this component, it is possible to infer that the degree of hardening at a certain position on the surface of the airbag is serious by observing the length of a certain air outlet rod that pops out, which may cause the risk of gas leakage in the future.

[0020] 4. The present invention is provided with a telescopic mechanism. The greater the pressure caused to the pushing ring connected to the bottom of the adsorption ring, the greater the air pressure discharged from the pushing ring, thereby driving the clapping plate to rotate outward faster and the stronger the impact force on the surface of the airbag. By setting up this mechanism, the squeezing force on the airbag can be automatically adjusted by different degrees of stretching the surface of the airbag, so that sufficient air pressure can be discharged from the inside of the airbag to meet the requirements of subsequent inspection of the airbag body.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] For example, see Figure 1-Figure 5 The present invention provides a technical solution: a vehicle suspension air path comprehensive detection device, including a bottom plate 1, a mobile platform 2 is fixedly connected to the top of the bottom plate 1, a working box 3 is fixedly connected to the top of the bottom plate 1, the working box 3 is fixedly connected to one end of the mobile platform 2, a placement groove 4 is opened on the inner wall of the working box 3, a detection component 6 is arranged on the inner wall of the mobile platform 2, and a telescopic mechanism 7 is arranged on the inner wall of the placement groove 4, and also includes:

[0033] The pushing mechanism 5 includes a telescopic plate 501 slidably connected to the inner walls of the moving platform 2 via sliders, a gas pump 502 is fixedly connected to the right side of the telescopic plate 501, a jet chamber 503 is fixedly connected to the bottom of the inner wall of the telescopic plate 501, a measuring component 505 is provided on the inner wall of the jet chamber 503, and pressure measuring components 504 are provided on both sides of the jet chamber 503.

[0034] The pressure measuring assembly 504 includes a pushing arm 5041 fixedly connected to both sides of the jet chamber 503, compression rings 5043 are fixedly connected to both sides of the inner wall of the pushing arm 5041, a pressure measuring tube 5042 is slidably connected to the surface groove of the pushing arm 5041, and a pushing column 5044 is fixedly connected to the end of the pushing arm 5041 away from the jet chamber 503.

[0035] The measuring component 505 includes a telescopic membrane 5051 fixedly connected to the bottom of the inner wall of the jet chamber 503, the end of the telescopic membrane 5051 away from the jet chamber 503 is fixedly connected to a push rod 5052, the end of the push rod 5052 away from the telescopic membrane 5051 is fixedly connected to an air outlet chamber 5056, both sides of the inner wall of the push rod 5052 are rotatably connected with extrusion rings 5053 through rotating shafts, the extrusion rings 5053 are made of soft material, when the extrusion ring 5053 is pushed by the telescopic ring 5054, it will rotate inward to the inside of the push rod 5052, the surface of the push rod 5052 is slidably connected with the telescopic ring 5054, the inner wall of the telescopic ring 5054 is slidably connected with a tamping rod 5055, one end of the tamping rod 5055 is installed with a sliding ball, the surface of the sliding ball is relatively smooth, when the tamping rod 5055 slides and contacts inside the air pipe, one end of the tamping rod 5055 is prevented from being stuck inside the air pipe due to excessive friction.

[0036] The working method of the first embodiment is as follows: the airbag is placed in the placement slot 4, and the pusher drives the telescopic plate 501 to slide on the inner wall of the moving platform 2 toward the working box 3. When the telescopic plate 501 drives the push rod 5052 to enter the trachea connected to the airbag, the air nozzle on the surface of the trachea is first blocked through the jet chamber 503, and then the compressed air is injected into the telescopic film 5051 by starting the gas pump 502. After receiving the compressed air, the inside of the telescopic film 5051 will expand outward and drive the push rod 5052 to extend into the inside of the trachea. The compressed air will be injected into the airbag through the air outlet chamber 5056, thereby driving the airbag to expand outward. When the outside of the airbag is squeezed, the compressed air inside will be pushed outward. The compressed air ejected from the trachea will generate airflow to push the telescopic ring 5054, so that the telescopic ring 5054 slides on the surface of the push rod 5052 toward the telescopic membrane 5051. During the sliding process, the inner wall of the telescopic ring 5054 will be squeezed with one end of the extrusion ring 5053. The greater the flow rate of the compressed air discharged from the inside of the airbag to the outside of the trachea, the stronger the driving force generated on the surface of the telescopic ring 5054. The longer the distance that the telescopic ring 5054 slides on the surface of the push rod 5052, the more the telescopic ring 5054 squeezes the extrusion ring 5053. When multiple extrusion rings 5053 squeeze the inside of the telescopic ring 5054, the telescopic ring 5054 will be squeezed. The air pressure film inside 054 causes extrusion, so that the air pressure inside the telescopic ring 5054 drives the ramming rod 5055 to expand and contract outward from the inside of the telescopic ring 5054, and the telescopic ramming rod 5055 squeezes the inner wall of the trachea, causing the inner wall of the trachea to be squeezed and deformed. When the trachea is in cold weather outdoors, the surface of the trachea will become brittle and more prone to external deformation. The degree of external deformation of the trachea can be observed to determine whether the gas storage level inside the airbag is sufficient and whether there is any leakage. Since the compression ring 5043 is in contact with the outside of the trachea, when the outside of the trachea is squeezed and deformed by the ramming rod 5055, the deformation The outside of the trachea squeezes the compression ring 5043, causing the compression ring 5043 to shrink inward inside the pushing arm 5041, thereby generating pressure inside the pushing arm 5041. When the inside of the pushing arm 5041 is subjected to pressure, it pushes the pressure measuring tube 5042, causing the pressure measuring tube 5042 to expand and contract outward from the inner wall of the pushing arm 5041. The degree of brittleness of a certain part of the trachea can be roughly inferred by the distance that the pressure measuring tube 5042 expands and contracts outward from the inside of the pushing arm 5041. When multiple pressure measuring tubes 5042 expand and contract outward from the inside of the pushing arm 5041, it can be determined that the inside of the trachea has been severely deformed due to the influence of the cold weather outdoors, and is not sufficient to be used to connect to the airbag in the automobile suspension.

[0037] Example 2: Based on Example 1, continue to refer to Figure 6The detection component 6 includes a detection ring 601, the bottom of the detection ring 601 is slidably connected to the inner wall of the movable platform 2 through a slider, and the inner wall of the detection ring 601 is rotatably connected to contact arms 602 on both sides through a rotating shaft, and the contact arms 602 are fixedly connected to the two sides of the contact arms 606. Both ends of the clamping arms 606 have sticky materials. When the clamping arms 606 contact the surface of the airbag, the clamping arms 606 will be fixedly adsorbed on the surface of the airbag. The top slot of the contact arm 602 is slidably connected to an air outlet rod 603, and the bottom of the inner wall of the contact arm 602 is fixedly connected to a contact film 604, and the inner wall of the contact film 604 is fixedly connected to a telescopic ball 605.

[0038] The working method of the second embodiment is as follows: when the telescopic disk 501 slides inwardly on the inner wall of the moving platform 2, the pushing column 5044 is inserted into the surface slot of the detection ring 601, and the detection ring 601 is pushed by the pushing column 5044, so that the detection ring 601 slides inwardly on the inner wall of the moving platform 2 to the surface of the placement groove 4. After the detection ring 601 is stuck on the surface of the airbag, the contact arm 602 on the inner wall of the detection ring 601 will contact the surface of the airbag, and the contact arm 602 will be fixed on the surface of the airbag through the adsorption of the clamping arm 606 on the surface of the airbag. When the airbag receives gas, it will expand outward. Since the airbag is made of rubber, When the airbag is exposed to cold weather for a long time, the surface of the airbag may become hard, resulting in reduced elasticity. At this time, the inside of the airbag may be deformed when it receives the gas and expands outward. After the deformation, a certain part of the airbag will squeeze the contact membrane 604, causing the telescopic ball 605 inside the contact membrane 604 to be pressurized, thereby discharging the gas inside the telescopic ball 605 outward into the contact arm 602, and squeezing the air outlet rod 603 outward through the gas. By observing the length of a certain air outlet rod 603 that pops out, it can be inferred that the hardening degree of a certain position on the surface of the airbag is serious, which may cause the risk of gas leakage in the future.

[0039] Example 3: Based on Example 2, continue to refer to Figure 7-Figure 8 The telescopic mechanism 7 includes a side plate 701, which is fixedly connected to the bottom of the inner wall of the working box 3. An extrusion assembly 706 is arranged on the top of the side plate 701. A feed pipe 702 is fixedly connected to one end of the side plate 701. The end of the feed pipe 702 away from the side plate 701 is fixedly connected to a placement tube 703. The placement tube 703 is fixedly connected to the inner wall of the placement groove 4. Adsorption rings 704 are slidably connected to the inner walls of the placement tube 703 on both sides through sliders. A pushing ring 705 is fixedly connected to the bottom of the adsorption ring 704. An air pressure groove is provided inside the pushing ring 705, and the pushing ring 705 has the characteristic of telescopic expansion. When one end of the pushing ring 705 is squeezed, it will telescope inward and generate air pressure to flow into the internal passage of the side plate 701. The end of the pushing ring 705 away from the adsorption ring 704 is fixedly connected to the bottom of the inner wall of the placement tube 703.

[0040] The extrusion assembly 706 includes a shrinking block 7061, which is fixedly connected to the top of the side plate 701. A telescopic rod 7062 is fixedly connected to the surface of the shrinking block 7061. A slot is provided inside the telescopic rod 7062. When pushed by the internal gas, it will expand and contract outward and push the pushing block 7064. The end of the telescopic rod 7062 away from the shrinking block 7061 is fixedly connected to the pushing block 7064. The pushing block 7064 is slidably connected to the inner wall of the side plate 701 through a slider.

[0041] The extrusion assembly 706 also includes a shift ring 7066, which is fixedly connected to the top of the side plate 701. The inner walls of the shift ring 7066 are slidably connected to a slap plate 7067 via a slider. The inner wall of the slap plate 7067 is slidably connected to a hitting plate 7068. One end of the hitting plate 7068 is disc-shaped. When the surface of the airbag is hit at multiple points, the inside of the airbag will be squeezed at multiple points and sufficient compressed gas will be discharged to meet the detection conditions. The bottom of the inner wall of the push block 7064 is fixedly connected to an extrusion tube 7063. Tube 7063 has a telescopic property and an air pressure chamber is opened inside it. When the pushing block 7064 slides outward on the inner wall of the side plate 701, the bottom telescopic membrane of the pushing block 7064 will be squeezed with the bottom of the inner wall of the side plate 701, thereby spraying the compressed gas inside the pushing block 7064 outward into the extrusion tube 7063, allowing the extrusion tube 7063 to expand and contract outward. A guide ring 7065 is fixedly connected to the top of the extrusion tube 7063, and the end of the guide ring 7065 away from the extrusion tube 7063 is fixedly connected to the surface of the slapping plate 7067.

[0042] The working method of the third embodiment of the present invention is as follows: after the detection ring 601 is stuck on the surface of the airbag, the detection ring 601 is used to squeeze the airbag, so that the airbag shrinks inward inside the placement groove 4. During the shrinkage process, the airbag pushes the adsorption ring 704, causing the adsorption ring 704 to slide toward the bottom on the inner wall of the placement tube 703. When the adsorption ring 704 slides downward, it squeezes the pushing ring 705. After the pushing ring 705 is squeezed, air pressure is generated and injected into the side plate 701 through the feeding pipe 702. The telescopic rod 7062 is pushed by the air pressure, so that the telescopic rod 7062 is retracted outward and pushes the pushing block 7064. When the pushing block 7064 is pushed and slides outward on the inner wall of the side plate 701, the air pressure is injected into the squeezing tube 7063 and drives it to expand and retract outward, and pushes the guide ring 7065, thereby driving The guide ring 7065 rotates outward and pushes the clapping plate 7067, so that the clapping plate 7067 rotates outward on the inner wall of the displacement ring 7066. When the clapping plate 7067 rotates outward to the surface of the airbag, the surface of the airbag is squeezed by the hitting disk 7068, so that the surface of the airbag is impacted and compressed air is discharged outward. The longer the distance the airbag is extended and retracted inside the placement tube 703, the greater the pressure applied to the pushing ring 705 connected to the bottom of the adsorption ring 704, which makes the amount of air pressure discharged from the pushing ring 705 greater, thereby driving the clapping plate 7067 to rotate outward faster, and the stronger the impact force on the surface of the airbag. The squeezing force on the airbag can be automatically adjusted by different degrees of stretching the surface of the airbag, so that sufficient air pressure can be discharged from the inside of the airbag to meet the requirements of subsequent inspection of the airbag body.
