Description

Technical Field

[0001] This invention belongs to the field of fuel system oil leakage testing technology, specifically a fuel system multi-directional sloshing oil leakage testing component. Background Technology

[0002] The function of a car's fuel system is to supply the engine with a certain amount of clean, well-atomized gasoline according to the engine's operating conditions, so that it can mix with a certain amount of air to form a combustible mixture. Before the assembled fuel system is installed and used, corresponding tests are often required to determine its performance, such as fuel leak tests, which can reflect the sealing and safety performance of the car's fuel system.

[0003] While traditional fuel system sloshing and leakage testing devices can meet the requirements of the sine curve and different strokes and frequencies for sloshing durability testing, they only use sloshing tests in one direction. This makes it difficult to accurately simulate the sloshing and bumping of a vehicle during normal driving. Consequently, it is impossible to accurately determine whether leakage will occur at the fuel system connection points, pipeline locations, engine location, and fuel tank location during normal driving, thus failing to achieve accurate fuel system sloshing tests.

[0004] On the other hand, traditional fuel system sloshing and oil leakage test devices are only designed for specific sizes and models of fuel systems, and cannot be well applied to different sizes and models of fuel systems, resulting in poor versatility. Summary of the Invention

[0005] To address the shortcomings of traditional fuel system sloshing and leakage testing devices, which only perform sloshing tests in one direction and cannot accurately simulate the sloshing and bumping of a vehicle during normal driving, thus failing to accurately determine whether leakage will occur at fuel system connection points, pipeline locations, engine locations, and fuel tank locations during normal driving, and consequently failing to achieve accurate fuel system sloshing tests, this invention provides a multi-directional fuel system sloshing and leakage testing component.

[0006] This invention is achieved through the following technical solution: A fuel system multi-directional sloshing oil leakage test assembly includes a multi-directional sloshing test power structure and a fuel system test fixing structure.

The left and right sides of the fuel line fixing component are respectively connected and installed to the first drive rod and the second drive rod.

[0007] A further improvement of the present invention is that the eccentric plate is connected to the first auxiliary control table in sequence through the first linkage displacement push rod and the piston push rod, and the auxiliary positioning plate is equipped with an internal guide plate for guiding the piston push rod to slide back and forth.

[0008] A further improvement of the present invention is that an inner guide plate is installed on the second auxiliary drive platform via an extended auxiliary arm, and the second drive rod is vertically slidably connected to the inner guide plate.

[0009] A further improvement of the present invention is that the oil pipe fixing component includes an adjustment mounting platform connected and installed with the first driving tie rod and the second driving tie rod. The adjustment mounting platform is equipped with a horizontally adjustable slider, and the horizontally adjustable slider is equipped with an adjustable slider, the adjustable slider is equipped with a height adjustment guide plate, and the height adjustment guide plate is equipped with an adjustable oil pipe retainer.

[0010] A further improvement of the present invention is that a first adjusting slot in the left-right direction is provided on the adjusting mounting platform. The first adjusting slot is slidably installed with the lower part of the lateral displacement slider. A plurality of first locking holes are provided on the side wall of the first adjusting slot. A second auxiliary reserved slot is provided at the lower part of the lateral displacement slider. Second locking pins that can be inserted and positioned with the first locking holes are installed on both sides of the second auxiliary reserved slot.

[0011] A further improvement of the present invention includes an auxiliary positioning platform fixedly installed inside the second auxiliary reserved slot. A pusher plate is provided on one side of the auxiliary positioning platform. A second linkage folding rod is rotatably installed at both ends of the auxiliary positioning platform. A first linkage folding rod is rotatably installed at both ends of the pusher plate. The first linkage folding rod and the second linkage folding rod are respectively rotatably connected to the second locking pin. A third auxiliary reserved slot is also provided at both ends of the pusher plate. A first pin and a first spring that can elastically support the first pin outward are slidably installed in the third auxiliary reserved slot. A positioning lock block that can be inserted into the first pin for positioning is provided on the transverse displacement slider.

[0012] A further improvement of the present invention is that a friction strip is installed on the lateral displacement slider, and a pressing screw capable of pressing the friction strip is installed on the adjusting slider.

[0013] A further improvement of the present invention is that the tubing retainer is vertically slidably installed on the height adjustment guide plate via a sliding sleeve plate. The height adjustment guide plate is provided with a plurality of second locking holes spaced vertically apart, and the sliding sleeve plate is provided with a third locking pin that can be inserted into the second locking holes for positioning.

[0014] A further improvement of the present invention is that the oil pipe fixing component is connected and installed to the two engine oil tank fixing components through the adjusting component; the adjusting component includes a stop limit block fixedly installed to the base plate, a driving pulley and a driven pulley connected by a transmission belt; a mounting rod that slides and fits with the engine oil tank fixing component is connected between the stop limit block and the adjusting mounting platform; a third motor that is connected to the driving pulley is installed on the adjusting mounting platform; the driven pulley is rotatably installed on the stop limit block; and a transmission fixing plate connected to the engine oil tank fixing component is connected and installed on the transmission belt.

[0016] As can be seen from the above technical solutions, the beneficial effects of the present invention are: The engine and fuel tank are positioned and installed using two engine fuel tank fixing components, and the fuel pipe connecting the engine and fuel tank is clamped and positioned using fuel pipe fixing components. A first motor drives an eccentric plate to rotate, and the eccentric design of the eccentric plate causes it to reciprocate back and forth on the first auxiliary distribution platform during rotation. The first auxiliary distribution platform then wobbles back and forth on the guide rail. A second motor drives a rotating plate to rotate, and a second linkage displacement push rod is connected to the eccentric position of the rotating plate. During rotation, the rotating plate, through the second linkage displacement push rod, drives the distribution slider to reciprocate vertically (up and down), thereby driving the first drive rod to reciprocate. Combined with the auxiliary support and guidance of the second auxiliary distribution platform and the second drive rod, the entire fuel system test fixing structure can form a multi-directional reciprocating wobbling motion, thus enabling multi-directional wobbling fuel system leakage testing. This accurately simulates the shaking and bumping of a vehicle during normal driving, providing accurate and reliable fuel system wobbling testing. Furthermore, by adjusting the speeds of the first and second motors, different road conditions can be simulated flexibly, making its applications more extensive and flexible.

[0033] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0034] like Figures 1-14 As shown, this invention discloses a multi-directional sloshing and oil leakage test assembly for a fuel system, comprising a multi-directional sloshing test power structure 1 and a fuel system test fixing structure 2. The multi-directional sway test power structure 1 includes a driven engagement module 5, a test power output module 6, a base plate 3, and two front-to-back guide rails 4 installed on the left and right sides of the base plate 3. The test power output module 6 includes a first auxiliary distribution platform 13 slidably connected to a guide rail 4 and an auxiliary positioning plate 7 fixedly connected to a base plate 3; a first motor 8 is installed on the auxiliary positioning plate 7, and an eccentric plate 9 is installed at the output end of the first motor 8. The eccentric position of the eccentric plate 9 is connected to the first auxiliary distribution platform 13; a stroke guide frame 14 is fixedly installed on the first auxiliary distribution platform 13, a second motor 15 is installed on the stroke guide frame 14, and a distribution slider 18 is vertically slidably installed on the stroke guide frame 14. A turnover plate 16 is installed at the output end of the second motor 15. The eccentric position of the turnover plate 16 is connected to the distribution slider 18 through a second linkage displacement push rod 17. A first driving pull rod 19 is fixedly installed on the distribution slider 18. The driven engagement module 5 includes a second auxiliary engagement platform 20 that is slidably connected to another guide rail 4, and a second driving pull rod 23 is slidably mounted vertically on the second auxiliary engagement platform 20; The fuel system test mounting structure 2 includes a fuel line mounting component 24 and an engine fuel tank mounting component connected to both ends of the fuel line mounting component 24. The left and right sides of the fuel line mounting component 24 are respectively connected and installed to the first drive rod 19 and the second drive rod 23. The engine fuel tank mounting component includes an engine mounting component 26 for mounting the engine and a fuel tank mounting component 27 for mounting the fuel tank. The engine mounting component 26 and the fuel tank mounting component 27 have the same structure.

[0035] The engine and fuel tank are positioned and installed using two engine fuel tank fixing components, and the fuel pipe connecting the engine and fuel tank is clamped and positioned using fuel pipe fixing component 24. The first motor 8 drives the eccentric plate 9 to rotate, and the eccentric design of the eccentric plate 9 causes it to reciprocate back and forth on the first auxiliary distribution platform 13 during rotation, causing the first auxiliary distribution platform 13 to sway back and forth on the guide rail 4. The second motor 15 drives the rotating plate 16 to rotate, and the second linkage displacement push rod 17 connects to the eccentric position of the rotating plate 16. This causes the rotating plate 16 to rotate, driving the sliding block 18 to reciprocate vertically (up and down) via the second linkage displacement push rod 17. This, in turn, drives the first driving pull rod 19 to reciprocate up and down. Combined with the auxiliary support and guidance of the second auxiliary driving platform 20 and the second driving pull rod 23, the fuel system test fixing structure 2 can thus form a multi-directional reciprocating sway, enabling fuel system sway leakage testing. This accurately simulates the swaying and bumping of a vehicle during normal driving, providing accurate and reliable fuel system sway testing. Furthermore, by adjusting the speeds of the first motor 8 and the second motor 15, different road conditions can be simulated, making its application more widespread and flexible. Overall, it is convenient to use and highly practical.

[0036] Before the shaking test, confirm that there is no oil leakage in the fuel system. After each hour of the shaking test, stop the machine and check it until the final result is obtained after fifteen hours.

[0037] The eccentric plate 9 is connected to the first auxiliary actuator 13 via the first linkage displacement push rod 10 and the piston push rod 12. The auxiliary positioning plate 7 is equipped with an internal guide plate 11 that guides the piston push rod 12 to slide back and forth. The two ends of the first linkage displacement push rod 10 are rotatably connected to the eccentric position of the eccentric plate 9 and the piston push rod 12, respectively. The internal guide plate 11 guides the piston push rod 12 to slide back and forth, ensuring the reliability and stability of the back and forth pushing of the first auxiliary actuator 13.

[0038] Among them, such as Figure 5 As shown, an inner guide plate 22 is installed on the second auxiliary control platform 20 via an extended auxiliary arm 21, and a second drive rod 23 is vertically slidably connected to the inner guide plate 22. Through the sliding fit between the inner guide plate 22 and the second drive rod 23, the second drive rod 23 can more effectively follow the first drive rod 19 in synchronous shaking (back and forth, up and down), thus ensuring the reliability of multi-directional shaking tests of the fuel system.

[0039] The oil pipe fixing component 24 includes an adjustment platform 28 connected and installed with the first drive rod 19 and the second drive rod 23. The adjustment platform 28 is equipped with a lateral displacement slider 32 that can slide left and right, an adjustment slider 33 that can slide forward and backward, a height adjustment guide plate 47 that is mounted on the adjustment slider 33, and an oil pipe retainer that can be raised and lowered. This allows for flexible adjustment of the oil pipe retainer's left-right, forward-backward, and up-down positions, making it suitable for different oil pipe layouts in fuel systems, with a wide range of applications and strong versatility.

[0040] The mixing platform 28 has a first mixing groove 29 in the left-right direction, which is slidably installed with the lower part of the lateral displacement slider 32. The side wall of the first mixing groove 29 has several first locking holes 30. The lower part of the lateral displacement slider 32 has a second auxiliary reserved groove 36, and second locking pins 46 are installed on both sides of the second auxiliary reserved groove 36 to be inserted and positioned with the first locking holes 30. By positioning and inserting the second locking pins 46 with the first locking holes 30 at different positions, the left-right position of the tubing retainer can be flexibly adjusted and reliably positioned.

[0041] Specifically, an auxiliary positioning platform 42 is fixedly installed inside the second auxiliary reserved slot 36. A pusher plate 38 is connected to one side of the auxiliary positioning platform 42 via a second spring 43. A second linkage folding rod 45 is rotatably installed at both ends of the auxiliary positioning platform 42. A first linkage folding rod 44 is rotatably installed at both ends of the pusher plate 38. The first linkage folding rod 44 and the second linkage folding rod 45 are respectively rotatably connected to the second locking pin 46. A third auxiliary reserved slot 39 is also provided at both ends of the pusher plate 38. A first pin 41 and a first spring 40 that can elastically support the first pin 41 outward are slidably installed in the third auxiliary reserved slot 39. A positioning lock block 37 that can be inserted into the first pin 41 for positioning is provided on the transverse displacement slider 32.

[0042] Pressing the first pin 41 in opposite directions causes it to press the first spring 40, disengaging the first pin 41 from the positioning lock block 37. This pulls the pusher plate 38 to move away from the auxiliary positioning platform 42, causing the pusher plate 38 to retract the second locking pin 46 via the first linkage folding rod 44 and the second linkage folding rod 45. The second locking pin 46 disengages from the first lock hole 30, and the lateral displacement slider 32 slides to the appropriate position in the first adjusting slot 29, aligning the second locking pin 46 with the first lock hole 30. Pressing down the adjusting slider 33 and pressing the first pin 41 in opposite directions causes it to press the first spring 40, pushing the pusher plate 38 towards the auxiliary positioning platform 42. This causes the second locking pin 46 to extend and engage with the corresponding first lock hole 30. Releasing the first pin 41 allows the first spring 40 to insert into the positioning lock block 37 under its elastic force, thus forming a double locking mechanism in the left and right directions. This is convenient to operate and has good reliability. When the second spring 43 is a compression spring, it can assist in the unlocking operation of the second locking pin 46; when the second spring 43 is a tension spring, it can ensure the reliability of the insertion and positioning of the second locking pin 46 and the first locking hole 30, and prevent it from coming out.

[0043] The transverse displacement slider 32 is equipped with a friction strip 35, and the adjusting slider 33 is equipped with a pressing screw 34 that can press the friction strip 35. By loosening the pressing screw 34, adjusting the position of the adjusting slider 33 within the transverse displacement slider 32, and tightening the pressing screw 34, the friction strip 35 is pressed onto the adjustment platform 28, thereby achieving flexible adjustment and reliable positioning of the oil pipe retainer in the forward and backward directions.

[0044] The tubing retainer is vertically slidably mounted on a height adjusting guide plate 47 via a sliding sleeve 49. The height adjusting guide plate 47 has several vertically spaced second locking holes 48. The sliding sleeve 49 has a third locking pin 51 that can be inserted into the second locking holes 48 for positioning. The sliding sleeve 49 has fourth auxiliary pre-reserved grooves 50 at both ends, and a third spring 52 is installed in the fourth auxiliary pre-reserved groove 50 to elastically support the third locking pin 51 outwards. Overcoming the elastic force of the third spring 52, the third locking pin 51 is pulled outwards, disengaging from the second locking holes 48. This pushes the sliding sleeve 49 to move up and down on the height adjusting guide plate 47, allowing the tubing retainer to slide to a suitable position. Then, the third locking pin 51 is released, and the third spring 52 elastically resets, pushing the third locking pin 51 back into the corresponding second locking hole 48, thus achieving flexible adjustment and reliable positioning of the tubing retainer.

[0045] The tubing clamp includes two interlocking semi-circular locking arms 54. A bidirectional mounting bracket 53 is mounted on the sliding sleeve 49. One end of each locking arm 54 is rotatably connected to the upper and lower ends of the bidirectional mounting bracket 53, respectively, and the other ends of each locking arm 54 are connected by bolts 55. The tubing is clamped by the two locking arms 54 and locked by the bolts 55, ensuring reliable tubing clamping.

[0046] The oil pipe fixing component 24 is connected and installed to the two engine oil tank fixing components through the adjusting component 25. The adjusting component 25 includes a stop limit block 57 fixedly installed to the base plate 3, a drive pulley 59 and a driven pulley 60 connected by a transmission belt 61. A mounting rod 56 that slides and fits with the engine oil tank fixing component is connected between the stop limit block 57 and the adjusting platform 28. A first auxiliary reserved slot 31 is opened on the adjusting platform 28. A third motor 58 connected to the drive pulley 59 is installed in the first auxiliary reserved slot 31. The driven pulley 60 is rotatably installed in the slot opened on the stop limit block 57. A transmission fixing plate 62 connected to the engine oil tank fixing component is connected and installed on the transmission belt 61. The third motor 58 drives the transmission belt 61 to rotate, and through the transmission fixing plate 62, it drives the engine oil tank fixing component to slide back and forth along the mounting rod 56 for adjustment. This allows for flexible adjustment of the distance between the engine oil tank fixing component and the oil pipe fixing component 24, thus adapting to oil pipes of different lengths in the fuel system. It has a wide range of applications and good versatility.

[0047] The engine oil tank fixing component includes a placement fixing platform 63 fixedly connected to the transmission fixing plate 62. The placement fixing platform 63 has a through hole 64 for sliding fitting with the mounting rod 56. Threaded push rods 65 are screwed onto the left and right sides of the placement fixing platform 63. The inner side of the threaded push rods 65 has a clamping plate 66 that can move left and right. An elastic band 67 is also installed on the placement fixing platform 63. Rotating the threaded push rods 65 can push the clamping plate 66 to clamp the engine or oil tank, and the elastic band 67 can bind the engine or oil tank, achieving convenient and reliable positioning and installation of the engine or oil tank.

[0048] This multi-directional sloshing and oil leakage test assembly for the fuel system uses two engine fuel tank fixing components to position and install the engine and fuel tank respectively, and a fuel pipe fixing component 24 to clamp and position the fuel pipe connecting the engine and fuel tank. By controlling the first motor 8 to drive the eccentric plate 9 to rotate, the eccentric design of the eccentric plate 9 causes it to reciprocate back and forth on the first auxiliary distribution platform 13 during rotation, resulting in a back-and-forth sloshing motion of the first auxiliary distribution platform 13 on the guide rail 4. By controlling the second motor 15 to drive the rotating plate 16 to rotate, the second linkage displacement push rod 17 interacts with the rotating plate... The plate 16 is eccentrically connected, causing the rotating plate 16 to drive the sliding block 18 to reciprocate vertically (up and down) during rotation via the second linkage displacement push rod 17. This, in turn, drives the first driving pull rod 19 to reciprocate up and down. Combined with the auxiliary support and guidance of the second auxiliary driving platform 20 and the second driving pull rod 23, the fuel system test fixing structure 2 can form a multi-directional reciprocating sway, thus enabling fuel system sway leakage testing. This accurately simulates the swaying and bumping of a vehicle during normal driving, providing accurate and reliable fuel system sway testing. Furthermore, by adjusting the speeds of the first motor 8 and the second motor 15, different road conditions can be flexibly simulated, making its application more widespread and flexible.
