Description

Technical Field

[0001] The present invention relates to the technical field of fuel cells, and particularly to a performance testing device for a fuel storage system of a fuel cell vehicle. Background Art

[0002] In the research and development and industrialization process of fuel cell vehicles (FCVs), as one of the key components, the performance of the fuel storage system plays a decisive role in the reliable operation and endurance of the entire vehicle. Since fuel cells mainly rely on hydrogen as the fuel source, an efficient hydrogen storage system not only needs to ensure safe and reliable hydrogen storage and transportation, but also must meet the stringent space, weight, and energy consumption requirements in the vehicle environment, while ensuring the ability to quickly refuel and release hydrogen under various working conditions.

[0003] Nowadays, after the hydrogen storage system is produced, manufacturers usually install the hydrogen storage system on a fuel cell vehicle for performance testing to detect the various performances of the hydrogen storage system in the vehicle. For example, after installing the hydrogen storage system on a fuel cell vehicle, the manufacturer will conduct an impact test on an object with the fuel cell vehicle to test the situation of the hydrogen storage system after the fuel cell vehicle is squeezed. However, during the above testing method, due to the large number of tests required, once the fuel cell vehicle or the hydrogen storage system is damaged, the fuel cell vehicle or the hydrogen storage system needs to be disassembled and replaced. Since the connection between the hydrogen storage system and the fuel cell vehicle is mostly by bolts, workers need to disassemble a large number of bolts during disassembly and replacement, which is not only time-consuming and laborious, but also troublesome to operate, and easily affects the testing efficiency of the hydrogen storage system. Summary of the Invention

[0004] In view of this, the present invention provides a performance testing device for a fuel storage system of a fuel cell vehicle, which can solve the disadvantages that after the fuel cell vehicle or the hydrogen storage system is damaged during testing, a large number of bolts need to be manually disassembled to disassemble and replace the fuel cell vehicle or the hydrogen storage system, resulting in a time-consuming, laborious, troublesome operation, and low efficiency process.

[0005] The technical solution is as follows: A performance testing device for a fuel storage system of a fuel cell vehicle, including an electric slide rail installed in the ground, and further including a connecting block, a rotating disk, a docking strip, a guide rail frame, a testing frame, a hydrogen storage system, a fixing mechanism, and a rotating mechanism. The connecting block is connected to the slider of the electric slide rail, and a chute I is opened on the connecting block. The rotating disk is rotatably connected to the connecting block, and a chute II is opened on the rotating disk. The docking strip is inserted into the rotating disk through the chute I and the chute II. The guide rail frame is connected to the docking strip, and the testing frame is slidably connected to the guide rail frame. The hydrogen storage system is installed on the testing frame. By pulling out the docking strip from the rotating disk, the guide rail frame, the testing frame, and the hydrogen storage system can be disassembled and replaced. The fixing mechanism is used to fix the testing frame on the guide rail frame, so that the testing frame can move synchronously with the guide rail frame and approach an object. Subsequently, by loosening the testing frame by the fixing mechanism, the testing frame can use inertia to impact the object, thereby performing a compressive performance test on the hydrogen storage system. The rotating mechanism is used to drive the rotating disk to rotate, so that the testing frame can be adjusted by rotation to impact other positions of the testing frame.

[0006] Furthermore, the rotating mechanism includes a servo motor, a gear, and a toothed ring.

[0009] Furthermore, a clamping mechanism is also included. The clamping mechanism includes a clamping plate and a spring. The clamping plate is slidably connected to the connecting block. A clamping groove is formed on the electromagnet. By clamping the clamping plate into the clamping groove, the clamping plate can limit the electromagnet. The two ends of the spring are respectively connected to the clamping plate and the connecting block.

[0010] Furthermore, a shielding mechanism is also included. The shielding mechanism includes a connecting frame, a winding member, and a shielding film. The two connecting frames are respectively connected to both sides of the electric slide rail. The winding member is arranged in the connecting frame. The two ends of the shielding film are respectively connected to the connecting block and the winding member, and the shielding film is used to prevent foreign objects from falling into the electric slide rail.

[0011] Furthermore, a collision mechanism is also included. The collision mechanism includes a support platform, a reduction motor, belt pulleys, a flat belt, mounting blocks, collision blocks, and bolts. The support platform is connected to the ground. The reduction motor is connected to the support platform. The two belt pulleys are both rotatably connected to the support platform. The flat belt is wound between the two belt pulleys. A plurality of mounting blocks are connected to the flat belt at intervals. The collision blocks are installed on the mounting blocks. The bolts are threadedly connected between the mounting blocks and the collision blocks, and the bolts are used to fix the collision blocks on the mounting blocks.

[0012] Furthermore, a roller frame is also included. The roller frame is connected to the support platform, and the roller frame is used for loading and unloading the collision blocks.

[0013] The beneficial effects of the present invention are as follows: 1. Through the cooperation of the connecting block, the rotating disk, the docking strip, the guide rail frame, the test frame, the hydrogen storage system, and the fixing mechanism, the present invention can impact the test frame with an object, so as to perform a pressure resistance test on the hydrogen storage system on the test frame. And when the test frame and the hydrogen storage system are severely damaged, the severely damaged test frame and hydrogen storage system can be quickly replaced, so as to continue the pressure resistance test on the hydrogen storage system. It is not only time-saving and labor-saving, convenient to operate, but also can improve the test efficiency of the hydrogen storage system.

[0014] 2. By setting the rotating mechanism, the present invention can make the test frame rotate automatically, so as to automatically adjust the orientation of the test frame, and then facilitate the operator to perform impact tests on other positions of the test frame.

Detailed implementation manners

[0027] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which the presently preferred embodiments of the invention are shown. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0028] Embodiment: A performance test device for a fuel storage system of a fuel cell vehicle, see Figures 1 - 4 As shown, it includes an electric slide rail 2; the electric slide rail 2 is installed in the ground 1; it also includes a connecting block 3, a rotating disk 4, a docking strip 5, a guide rail frame 6, a test frame 7, a hydrogen storage system 8, a fixing mechanism and a rotating mechanism; the connecting block 3 is connected to the slider of the electric slide rail 2, so that the electric slide rail 2 can drive the connecting block 3 to move, and two sliding grooves I 31 are opened on the connecting block 3; the rotating disk 4 is rotatably connected to the connecting block 3, and two sliding grooves II 41 are opened on the rotating disk 4; both docking strips 5 are inserted into the rotating disk 4 through the sliding grooves I 31 and the sliding grooves II 41, and the material of the docking strip 5 is iron; the guide rail frame 6 is connected between the tops of the two docking strips 5; the test frame 7 is slidably connected to the guide rail frame 6, and the test frame 7 uses the appearance material of a fuel cell vehicle; the hydrogen storage system 8 is installed on the test frame 7. By pulling out the docking strip 5 from the rotating disk 4, the guide rail frame 6, the test frame 7 and the hydrogen storage system 8 can be quickly disassembled and replaced; the fixing mechanism is used to fix the test frame 7 on the guide rail frame 6, so that the connecting block 3 can drive the rotating disk 4, the docking strip 5, the guide rail frame 6 and the test frame 7 to move, so that the test frame 7 gradually approaches the object. Subsequently, the fixing mechanism releases the test frame 7, and the connecting block 3, the rotating disk 4, the docking strip 5 and the guide rail frame 6 stop moving, so that the test frame 7 can use inertia to impact the object, thereby performing a compression performance test on the hydrogen storage system 8; the rotating mechanism is used to drive the rotating disk 4 to rotate, so that the test frame 7 can be adjusted by rotation, so as to impact other positions of the test frame 7, so that people can perform a compression performance test on the hydrogen storage system 8 by impacting other positions of the test frame 7.

[0029] See Figure 3 As shown, the rotating mechanism includes a servo motor 9, a gear 10 and a toothed ring 11; the servo motor 9 is connected to the slider of the electric slide rail 2; the gear 10 is connected to the output shaft of the servo motor 9, so that the servo motor 9 can drive the gear 10 to rotate; the toothed ring 11 is connected to the rotating disk 4, and the gear 10 meshes with the toothed ring 11, so that when the gear 10 rotates, it can drive the toothed ring 11 and the rotating disk 4 to rotate.

[0030] See Figure 2 and Figure 4 As shown, the fixing mechanism includes an electric push rod I 12 and a clamp 13; two electric push rods I 12 are symmetrically connected to the guide rail frame 6; the clamp 13 is connected to the telescopic rod of the electric push rod I 12, so that the electric push rod I 12 can drive the clamp 13 to move and clamp and fix the test frame 7.

[0031] During use, fix the object to be impacted on the ground 1, position the object directly to the right of the test stand 7, and then control the electric slide rail 2 to drive the connecting block 3 to accelerate and move to the right, thereby driving the rotating disk 4, the docking bar 5, the guide rail frame 6, and the test stand 7 to accelerate and move to the right, causing the connecting block 3 and the test stand 7 to gradually approach the object on the ground 1. When the connecting block 3 and the object are within a certain range, control the electric slide rail 2 to drive the connecting block 3 to stop moving, causing the rotating disk 4, the docking bar 5, and the guide rail frame 6 to stop moving. At the same time, control the electric push rod I 12 to drive the jaws 13 to move towards each other, releasing the test stand 7 from the jaws 13. As a result, the test stand 7 will not stop moving with the guide rail frame 6 and will continue to slide to the right due to inertia, causing the test stand 7 to collide with the object, thereby conducting a pressure resistance test on the hydrogen storage system 8 on the test stand 7. After the hydrogen storage system 8 on the test stand 7 completes this pressure resistance test, push the test stand 7 to move leftward to reset. Then, control the electric push rod I 12 to drive the jaws 13 to move away from each other to reset, causing the jaws 13 to clamp the test stand 7. Then, control the electric slide rail 2 to drive the connecting block 3 to accelerate and move leftward to reset, thereby driving the rotating disk 4, the docking bar 5, the guide rail frame 6, and the test stand 7 to accelerate and move leftward to reset. After that, the operator can inspect the test stand 7 and the hydrogen storage system 8. If no serious damage is detected in the test stand 7 and the hydrogen storage system 8, the servo motor 9 can be used to drive the gear 10 to rotate, thereby driving the toothed ring 11, the rotating disk 4, the docking bar 5, the guide rail frame 6, and the test stand 7 to rotate, and then adjusting the orientation of the test stand 7. After adjustment, repeat the above operations to conduct an impact test on other positions of the test stand 7, and then conduct a pressure resistance test on the hydrogen storage system 8 again. If serious damage is detected in the test stand 7 and the hydrogen storage system 8, the test stand 7 can be pulled forward to move, thereby driving the guide rail frame 6 and the docking bar 5 to move forward, causing the docking bar 5 to leave the chute II 41 and the chute I 31, and thus separating the docking bar 5 from the connecting block 3. Then, another set of guide rail frame 6, test stand 7, and hydrogen storage system 8 can be connected to the chute I 31 and the chute II 41 using the docking bar 5, and the docking bar 5 of the other set can be docked with the connecting block 3. In this way, it is possible to quickly replace the severely damaged test stand 7 and hydrogen storage system 8 to continue the pressure resistance test on the hydrogen storage system 8.

[0032] See Figure 5 and Figure 6As shown in the figure, it further includes a push-pull mechanism, which includes a guide rail frame 14, an electric push rod II 15, an iron sheet 16 and an electromagnet 17; the guide rail frame 14 is connected to the ground 1; two electric push rods II 15 are both connected to the guide rail frame 14; the iron sheet 16 is connected to the telescopic rod of the electric push rod II 15, so that the electric push rod II 15 can drive the iron sheet 16 to move; two electromagnets 17 are both movably installed in the connecting block 3, and the two electromagnets 17 are respectively located in two sliding grooves I 31. When the electromagnet 17 is energized, the electromagnet 17 can use magnetic force to attract the iron sheet 16 and the docking strip 5, so that when the iron sheet 16 moves, it can drive the docking strip 5 to move synchronously through the electromagnet 17.

[0033] See Figure 7 As shown in the figure, it further includes a positioning mechanism, which includes a clamping plate 18 and a spring 20; the clamping plate 18 is slidably connected to the connecting block 3; clamping grooves 19 are opened on both of the two electromagnets 17. By clamping the clamping plate 18 into the clamping grooves 19, the clamping plate 18 can limit the electromagnet 17; both ends of the spring 20 are respectively connected to the clamping plate 18 and the inside of the connecting block 3.

[0034] When the test stand 7 and the hydrogen storage system 8 detect serious damage, the electromagnet 17 can be energized, so that the electromagnet 17 uses magnetic force to attract the docking strip 5 and the iron sheet 16. Subsequently, the clamping plate 18 is pulled to move to the right, and the spring 20 is compressed, so that the clamping plate 18 releases the electromagnet 17. Then, the iron sheet 16, the electromagnet 17 and the docking strip 5 are driven forward by the electric push rod II 15, so that the docking strip 5 moves forward into the guide rail frame 14, thereby driving the guide rail frame 6 and the test stand 7 to move forward, and further separating the docking strip 5 from the connecting block 3. In this way, it is possible to replace manual labor to pull out the seriously damaged test stand 7; then the electromagnet 17 is powered off, so that the electromagnet 17 releases the docking strip 5 and the iron sheet 16, and then the docking strip 5, the guide rail frame 6, the test stand 7 and the hydrogen storage system 8 are removed from the guide rail frame 14. Then, another set of docking strip 5, guide rail frame 6, test stand 7 and hydrogen storage system 8 are placed on the guide rail frame 14, and the docking strip 5 is inserted into the guide rail frame 14 to contact the electromagnet 17. Subsequently, the electromagnet 17 is energized again, so that the electromagnet 17 uses magnetic force to attract the docking strip 5 and the iron sheet 16. Then, the iron sheet 16, the electromagnet 17 and the docking strip 5 are driven backward by the electric push rod II 15 to reset, so that the docking strip 5 moves backward into the connecting block 3 through the chute I 31 and the chute II 41, thereby driving the guide rail frame 6 and the test stand 7 to move backward to reset, and further docking the docking strip 5 with the connecting block 3. In this way, it is possible to replace manual labor to push back another set of test stands 7; then the electromagnet 17 is powered off again, so that the electromagnet 17 releases the docking strip 5 and the iron sheet 16, and releases the clamping plate 18. The spring 20 returns to its original state, and the spring 20 drives the clamping plate 18 to move to the left to reset, so that the clamping plate 18 clamps the electromagnet 17, thereby limiting the electromagnet 17 and the docking strip 5 to prevent the electromagnet 17 and the docking strip 5 from moving randomly in the connecting block 3, thereby affecting the pressure resistance test of the hydrogen storage system 8.

[0035] See Figure 8 and Figure 9 As shown, it further includes a shielding mechanism, and the shielding mechanism includes a connecting frame 21, a winding member 22 and a shielding film 23; the two connecting frames 21 are respectively connected to the left and right sides of the electric slide rail 2; the winding member 22 is composed of a winding wheel and a hairspring. The winding wheel is rotatably connected to the connecting frame 21, and a hairspring is connected between the winding wheel and the inside of the connecting frame 21; one end of the shielding film 23 is connected to the winding wheel of the winding member 22, and the other end of the shielding film 23 is connected to the connecting block 3, and the shielding film 23 can be used to block foreign objects from falling into the electric slide rail 2.

[0036] When the connecting block 3 moves left or right, the connecting block 3 will pull the shielding film 23 on one side, causing the shielding film 23 to unwind from the winding wheel of the winding member 22 on the same side, and deforming the spring of the winding member 22 on the same side. At the same time, the connecting block 3 will loosen the shielding film 23 on the other side. At this time, the spring of the winding member 22 on the other side will use its elasticity to drive the winding wheel on the same side to wind up the shielding film 23 on the same side; when the test stand 7 collides with an object, some debris parts will be generated during the collision. At this time, by setting the shielding film 23, it can block the debris parts falling into the electric slide rail 2 to prevent the debris parts from falling into the electric slide rail 2 and causing jamming.

[0037] See Figure 8 and Figure 10 As shown, it further includes a collision mechanism. The collision mechanism includes a support platform 24, a reduction motor 25, a pulley 26, a flat belt 27, a mounting block 28, a collision block 29, and a bolt 30; the support platform 24 is connected to the ground 1; the reduction motor 25 is connected to the upper part of the front side of the support platform 24; two pulleys 26 are rotatably connected to the front and rear sides of the support platform 24; two flat belts 27 are wound between the two pulleys 26; three groups of mounting blocks 28 are connected between the two flat belts 27. The number of each group of mounting blocks 28 is two, and each group of mounting blocks 28 is distributed vertically. A collision block 29 is connected to each group of mounting blocks 28, and the shape of the collision block 29 can be various shapes to simulate the terrain of various scenarios and collide with the test stand 7; the bolt 30 is threadedly connected between the mounting block 28 and the collision block 29, and the bolt 30 is used to fix the collision block 29 on the mounting block 28.

[0038] See Figure 8 and Figure 10 As shown, it further includes a roller stand 301; two roller stands 301 are symmetrically connected to the lower part of the left side of the support platform 24, and the roller stand 301 is used to assist the collision block 29 in loading and unloading.

[0039] In use, the reduction motor 25 can be used to drive the pulley 26 to rotate, thereby driving the flat belt 27 and the mounting block 28 to rotate. When the mounting block 28 rotates directly above the roller frame 301, the collision block 29 can be placed on the roller frame 301. Then, the roller frame 301 is used to push the collision block 29 into contact with the mounting block 28. Subsequently, the collision block 29 is installed on the mounting block 28 using bolts 30. The above operation is repeated to install three mounting blocks 28 with different shapes on the three mounting blocks 28 using bolts 30 respectively. Then, according to the test requirements of the operator, the reduction motor 25 can be used to drive the pulley 26 to rotate, thereby driving the flat belt 27, the mounting block 28, and the collision block 29 to rotate, so that the required collision block 29 rotates to the exact right of the test stand 7. In this way, it is convenient for the operator to switch the collision block 29 that needs to impact the test stand 7, thereby facilitating the operator to simulate the terrain of various scenarios and collide with the test stand 7. After that, when it is necessary to replace the collision block 29 on the mounting block 28, the reduction motor 25 can be used again to drive the pulley 26 to rotate, thereby driving the flat belt 27, the mounting block 28, and the collision block 29 to rotate. When the collision block 29 rotates directly above the roller frame 301, the collision block 29 can be removed from the mounting block 28, and the removed collision block 29 is discharged using the roller frame 301. Finally, another collision block 29 is installed on the mounting block 28 using the roller frame 301.
