Description

Technical Field

[0001] This invention relates to the field of life testing technology, and specifically to a fuel cell high-load multi-life testing device. Background Technology

[0002] The evaluation method for the lifespan of automotive proton exchange membrane fuel cell stacks involves testing. While the high-load operation time of the hydrogen pump is relatively short, a 2000-hour high-load test duration should be sufficient to meet current stack lifespan requirements. Due to the extended testing time, multiple fuel cells are tested simultaneously, resulting in multi-lifespan testing. However, this requires a large area for simultaneous testing of multiple fuel cells. To reduce the testing area, stacking multiple fuel cells is commonly used. However, when testing the next batch of stacked cells, the cells from the previous batch need to be transferred, a time-consuming process. The replacement process requires waiting for both the forklift driver and the testing personnel to be available, which often overlaps, leading to prolonged equipment downtime and impacting the testing process. Therefore, a testing device is needed that allows the operator to replace batteries independently, without requiring a shared timeframe between the operator and the forklift driver. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a high-load, long-life testing device for fuel cells, and to design a testing device that allows an experimenter to independently replace the battery without requiring the experimenter and forklift driver to have a shared time point.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The present invention provides a fuel cell high-load multi-life testing device, including a guide slide and a lifting frame that can be vertically slidably installed on the guide slide. The lifting frame is provided with multiple mounting seats, each of which can be horizontally slidably installed on the lifting frame. A lifting mechanism for pushing the lifting frame to move vertically upward is fixedly installed on the guide slide. The testing connector is used to be horizontally slidably inserted into one side of the fuel cell.

[0005] Preferably, the lifting mechanism includes a rack, a gear, a worm gear, and a worm. The rack is fixedly mounted on the lifting frame, the gear is rotatably mounted on the guide frame, the gear is fixedly connected to the worm gear through a rotating shaft, the worm meshes with the worm gear, and the worm is rotatably mounted on the guide frame.

[0006] Preferably, at least two guide columns are fixedly installed on the guide slide, the two guide columns are vertically arranged, and a linear bearing that is slidably connected to the guide columns is provided at the bottom of the lifting frame.

[0007] Preferably, a limit plate is fixedly installed on the side of the lifting frame near the detection joint.

[0008] Preferably, the outer edge of the guide post contacts the side of the mounting base away from the test connector. When the fuel cell is being tested, the outer edge of the guide post contacts one side of the mounting base. When the fuel cell that has completed the test is pushed upward, the outer edge of the guide post separates from the mounting base.

[0009] Preferably, the bottom of the mounting base is provided with multiple slides, and the lifting frame is provided with slide rails that are slidably connected to the slides.

[0010] Preferably, a second limiting plate is fixedly installed on the side of the fuel cell away from the first limiting plate.

[0011] Preferably, the guide rail is provided with multiple support seats for supporting the lifting frame.

[0012] The beneficial effects of this invention are as follows: After the first batch of fuel cells is tested, the experimenter can replace the battery independently without the need for a forklift, reducing downtime of the testing equipment and avoiding affecting the testing process. Furthermore, the mechanical operation of the lifting frame for up and down movement avoids the use of hydraulic cylinders for pushing, thereby preventing damage to the testing device in case of oil leakage or electrical faults. After the test is completed, the original lock on the mounting base can be automatically released, reducing the number of operation steps. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: This invention provides a fuel cell high-load, long-life testing device, such as... Figure 1 As shown, the system includes a guide slide 1 and a lifting frame 2 that can be vertically slidably mounted on the guide slide 1. The lifting frame 2 is equipped with multiple mounting seats 2a, each of which can be horizontally slidably mounted on the lifting frame 2. A lifting mechanism 5 is fixedly mounted on the guide slide 1 to push the lifting frame 2 vertically upward. A detection connector 3 is used to horizontally slide and connect to one side of a fuel cell 4. After the first batch of batteries is tested, the lifting mechanism 5 is driven to push the lifting frame 2 vertically upward, causing the fuel cell 4 originally connected to the detection connector 3 to be pushed upward. The next layer of fuel cell 4 then moves upward one layer, allowing it to connect to the horizontally slidable detection connector 3, thus enabling the testing of the next layer of batteries. It is conceivable that there can be multiple detection connectors 3, with multiple detection connectors 3 configured to slide horizontally, making the wiring connection more convenient when multiple detection connectors 3 are connected to multiple lifting frames 2. The lifting mechanism 5 can be a hydraulic cylinder or a hydraulic electric push rod, or it can be a purely mechanical lifting method.

[0022] If the lifting mechanism 5 uses a hydraulic cylinder or a hydraulic electric push rod for lifting, due to prolonged testing, if a hydraulic oil leak or electrical fault occurs, the lifting frame 2 will inevitably fall. The fall of the lifting frame 2 will create a shearing force between it and the testing connector 3, damaging the testing connector 3. Therefore, if... Figure 2As shown, the lifting mechanism 5 includes a rack 5a, a gear 5b, a worm gear 5c, and a worm 5d. The rack 5a is fixedly mounted on the lifting frame 2. The gear 5b is rotatably mounted on the guide slide 1. A rotating seat rotatably connected to the gear 5b is fixedly mounted on the guide slide 1. The gear 5b is fixedly connected to the worm gear 5c via a rotating shaft. The worm 5d meshes with the worm gear 5c and is rotatably mounted on the guide slide 1. A handle 5e is provided at one end of the worm 5d. Driving the worm 5d through the handle causes it to rotate, which in turn causes the gear 5b to rotate. This means the rack 5a drives the lifting frame 2 to move up and down. The transmission is achieved through the worm gear 5c and the worm 5d, eliminating the need for an external locking mechanism during lifting. The meshing between the worm gear 5c and the worm 5d locks the lifting frame 2 securely. The number of racks 5a is not limited to one pair; multiple pairs are possible. Figure 2 The image shows only one side of the lifting frame 2 with the lifting mechanism 5 installed. In actual use, the other side of the lifting frame 2 is also equipped with the lifting mechanism 5. The worm gear 5d between the two lifting frames 2 is connected by a connecting shaft, so that the lifting frame 2 can be lifted and lowered stably.

[0023] like Figure 3 As shown, at least two guide posts 6 are fixedly installed on the guide slide 1. The two guide posts 6 are vertically arranged, and a linear bearing that is slidably connected to the guide posts 6 is installed at the bottom of the lifting frame 2. Through the cooperation of the guide posts 6 and the linear bearing, the lifting frame 2 can slide vertically. Generally, the guide posts 6 pass through the middle of the lifting frame 2.

[0024] like Figure 2 As shown, a limiting plate 2b is fixedly installed on the side of the lifting frame 2 near the detection connector 3. By setting the limiting plate 2b, excessive thrust is applied to the fuel cell 4 when the fuel cell 4 and the detection connector 3 are connected, which would cause the fuel cell 4 to be pushed out together with the mounting base 2a.

[0025] The outer edge of the guide post 6 contacts the side of the mounting base 2a away from the detection connector 3. Through the cooperation of the guide post 6 and the limiting plate 2b, both sides of the mounting base 2a are locked, preventing displacement during its ascent. When the fuel cell 4 is being tested, the outer edge of the guide post 6 contacts one side of the mounting base 2a. When the tested fuel cell 4 is pushed upwards, the outer edge of the guide post 6 separates from the mounting base 2a. This means the guide post 6 has a limited height. After testing, the mounting base 2a is pushed upwards, and its height exceeds the top of the guide post 6, causing the mounting base 2a to lose the limiting effect of the guide post 6, allowing it to slide horizontally. In this way, as... Figure 1As shown, the mounting base 2a has a clamping device on the side away from the test connector 3. By horizontally pushing the mounting base 2a, the fuel cell 4 to be tested is brought closer to the clamping device, allowing the tested battery to be removed. Furthermore, the mounting base 2a can be provided with a clearance groove for the forklift claw to pass through from bottom to top, allowing the forklift claw to lift the fuel cell 4. After lifting, the battery is removed by reversing the forklift. After each layer of batteries is removed, the mounting base 2a is pushed back until it contacts the limiting plate 2b to avoid obstructing the forklift claw.

[0026] like Figure 5 As shown, the bottom of the mounting base 2a is provided with multiple slides 2c, and the lifting frame 2 is provided with slide rails 2d that are slidably connected to the slides 2c. By setting the slides 2c and slide rails 2d, the mounting base 2a can slide horizontally. The number of slides 2c can be four, and the four slides 2c are respectively installed at the four ends of the mounting base 2a to provide better support for the mounting base 2a. The lifting frame 2 has two slide rails 2d that are connected to the slides 2c.

[0027] like Figure 5 As shown, a second limiting plate 2e is fixedly installed on the side of the fuel cell 4 away from the first limiting plate 2b. The second limiting plate 2e limits the mounting base 2a to prevent the mounting base 2a from sliding out of the slide rail 2d when the fuel cell 4 is removed.

[0028] like Figure 1 As shown, the guide slide 1 is equipped with multiple support seats 7 for supporting the lifting frame 2. When the lifting frame 2 moves to its highest point, it is supported by the support seats 7, leaving a protective gap between the lifting frame 2 and the guide slide 1. The top of the support seat 7 is a rubber pad structure.

[0029] This high-load, multi-life testing device for fuel cells allows technicians to replace batteries independently after the first batch of fuel cell tests are completed, eliminating the need for forklifts, reducing downtime of the testing equipment, and preventing disruption to the testing process. Furthermore, the mechanical operation of the lifting frame for vertical movement avoids the use of hydraulic cylinders, thus preventing damage to the testing device in case of oil leaks or electrical faults. After the test is completed, the locking mechanism on the mounting base can be automatically released, reducing the number of steps required.

[0030] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
