Description

Technical Field

[0001] This utility model relates to the technical field of hydrogen fuel cell testing equipment, specifically a hydrogen fuel cell impact testing device. Background Technology

[0002] The difference between hydrogen fuel cells and traditional lithium batteries is that hydrogen fuel cells are power generation devices and are widely used in new energy vehicles. In order to ensure that the batteries can maintain excellent performance in various usage environments, hydrogen fuel cells are usually subjected to rigorous testing, including impact testing. The purpose of impact testing is to simulate the impact, drop and other unexpected situations that hydrogen fuel cells may encounter in actual use, so as to evaluate the safety and performance of the batteries under these extreme conditions.

[0003] In existing impact tests, hydrogen fuel cells are typically placed flat on a conveyor belt and passed sequentially through an impact structure. While this method improves testing efficiency, it results in a fixed and unadjustable impact angle and force, making it unsuitable for diverse testing requirements. Furthermore, the lack of effective connection between the existing hydrogen fuel cell and the conveyor belt during testing causes the fuel cell to become unstable upon impact, easily sliding and shifting along the belt. This leads to deviations in the force applied to the cell by the impact structure, affecting the accuracy of the impact test results. Utility Model Content

[0004] The purpose of this invention is to provide a hydrogen fuel cell impact detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydrogen fuel cell impact testing device, comprising a housing, an electric push rod mounted on the top of the housing, a pressure plate rotatably connected to the output end of the electric push rod, a second slot provided at the bottom end of the pressure plate, a turntable provided directly below the pressure plate, a first slot provided at the top end of the turntable, a retaining strip embedded at one end of the first slot, a second rotary motor mounted on the inner side of the bottom of the housing, a fixed frame provided on the inner side of the middle of the housing, a first rotary motor provided at the bottom of the fixed frame, a rotating shaft provided at the output end of the first rotary motor, a movable frame provided on the inner side of the fixed frame, a horizontal bar provided on one side wall of the movable frame, a vertical bar fixedly connected to the end of the horizontal bar, and impact balls fixedly connected to the top and bottom ends of the vertical bar.

[0006] Preferably, the output end of the second rotary motor is engaged with the bottom end of the turntable, and the turntable is rotatably connected to the outer casing via the second rotary motor.

[0007] Preferably, a notch is provided in the middle of the front of the outer casing, and the notch is connected to the end of the first card slot near the card strip.

[0008] Preferably, a first eccentric shaft gear is provided in the middle of the rotating shaft, a second eccentric shaft gear is engaged with the outer wall of the first eccentric shaft gear, and a chuck is sleeved on the outer side of the first eccentric shaft gear and the second eccentric shaft gear.

[0009] Preferably, the first eccentric shaft gear is rotatably connected to the fixed frame via a rotating shaft, and the first eccentric shaft gear is rotatably connected to the chuck via the fixed frame.

[0010] Preferably, the two ends of the eccentric shaft of the second eccentric shaft gear are movably connected to the top and bottom ends of the movable frame, respectively, and the movable frame is slidably connected to the fixed frame through the second eccentric shaft gear.

[0011] Preferably, the crossbar is movably connected to the fixed frame and the side wall in the middle of the outer casing via a movable frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This hydrogen fuel cell impact testing equipment, through the setting of a turntable, vertical rod, impact ball, first rotary motor and second rotary motor, enables the fuel cell to rotate horizontally with the turntable, so that different positions on the surface of the battery can be impacted by the impact ball. Moreover, the contact area between the impact ball and the hydrogen fuel cell is smaller, making it easier to generate a larger impact force. At the same time, it can impact different parts of the hydrogen fuel cell, thereby meeting the testing requirements of different hydrogen fuel cells.

[0013] 2. This hydrogen fuel cell impact testing equipment, through the setting of a pressure plate, a first slot, a second slot, and a locking bar, ensures that when the hydrogen fuel cell is subjected to impact testing, the top of the battery will be locked in the second slot at the bottom of the pressure plate, while the bottom of the battery will be locked in the first slot of the turntable. This allows the fuel cell to maintain a stable state when subjected to impact, making it less likely for the impact force of the impact ball on the hydrogen fuel cell to deviate, thereby reducing the adverse effects on the impact test results.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figures 1 to 5As shown, the hydrogen fuel cell impact testing device of this embodiment includes a housing 1. An electric push rod 2 is installed at the top of the housing 1. The output end of the electric push rod 2 is rotatably connected to a pressure plate 3. A second slot 19 is provided at the bottom of the pressure plate 3. A turntable 6 is provided directly below the pressure plate 3. A first slot 7 is provided at the top of the turntable 6. A locking strip 8 is embedded at one end of the first slot 7. A second rotary motor 16 is installed on the inner side of the bottom of the housing 1. A fixed frame 10 is provided on the inner side of the middle of the housing 1. A first rotary motor 12 is provided at the bottom of the fixed frame 10. A rotating shaft 11 is provided at the output end of the first rotary motor 12. A movable frame 14 is provided on the inner side of the fixed frame 10. A horizontal bar 15 is provided on one side wall of the movable frame 14. A vertical bar 4 is fixedly connected to the end of the horizontal bar 15. An impact ball 5 is fixedly connected to both the top and bottom of the vertical bar 4.

[0020] Specifically, the middle part of the outer shell 1 has a hollow structure, allowing the hydrogen fuel cell to be tested to be smoothly placed into the turntable 6 and pressed and fixed by the descending pressure plate 3. A rotating connector is also provided at the top center of the pressure plate 3, allowing it to rotate with the hydrogen fuel cell when pushed downwards by the electric push rod 2, thus achieving horizontal rotation of the hydrogen fuel cell on the equipment. The diameter of the turntable 6 is the same as the diameter of the pressure plate 3, and the first slot 7 and the second slot 19 face the same direction, allowing the top and bottom of the hydrogen fuel cell to be simultaneously squeezed into the first slot 7 and the second slot 19. The two slots 19 are used to keep the hydrogen fuel cell stable on the pressure plate 3 and the turntable 6. The function of the locking bar 8 is to limit the fuel cell placed on the first slot 7, so that the fuel cell can remain stable when it is impacted, thus facilitating the impact ball 5 to accurately apply the force to the hydrogen fuel cell. The function of the fixed frame 10 is to limit the range of motion of the chuck 13 and the movable frame 14, so that the movable frame 14 can push the crossbar 15 to make reciprocating linear motion, thereby realizing the driving of the crossbar 15 on the vertical bar 4 and the impact ball 5 on the vertical bar 4.

[0021] Furthermore, the output end of the second rotary motor 16 is engaged with the bottom end of the turntable 6. The turntable 6 is rotatably connected to the outer shell 1 through the second rotary motor 16, so that the turntable 6 can rotate smoothly on the outer shell 1, driving the hydrogen fuel cell to rotate horizontally on the equipment, thereby realizing the adjustment of the angle and position of the impact on the hydrogen fuel cell.

[0022] Furthermore, a notch 9 is provided in the middle of the front of the outer casing 1. The notch 9 is connected to the end of the first slot 7 near the card strip 8. The function of the notch 9 is to facilitate pushing the hydrogen fuel cell into the first slot 7 of the turntable 6, thereby making it easier for the user to operate.

[0023] Furthermore, a first eccentric shaft gear 17 is provided in the middle of the rotating shaft 11, and a second eccentric shaft gear 18 is meshed on the outer wall of the first eccentric shaft gear 17. A chuck 13 is sleeved on the outer side of the first eccentric shaft gear 17 and the second eccentric shaft gear 18. After being driven by the rotating shaft 11, the first eccentric shaft gear 17 can mesh with the second eccentric shaft gear 18 to rotate, causing the eccentric shaft on the second eccentric shaft gear 18 to drive the movable frame 14 to slide within the fixed frame 10, thereby realizing the pushing of the crossbar 15 by the movable frame 14.

[0024] Furthermore, the first eccentric shaft gear 17 is rotatably connected to the fixed frame 10 via the rotating shaft 11, and the first eccentric shaft gear 17 is rotatably connected to the chuck 13 via the fixed frame 10. When the first eccentric shaft gear 17 and the second eccentric shaft gear 18 are meshed, they can be limited by the chuck 13, which helps the first eccentric shaft gear 17 and the second eccentric shaft gear 18 to maintain a relatively stable state when meshing and rotating.

[0025] Furthermore, the two ends of the eccentric shaft of the second eccentric shaft gear 18 are movably connected to the top and bottom ends of the movable frame 14, respectively. The movable frame 14 is slidably connected to the fixed frame 10 through the second eccentric shaft gear 18, so that the second eccentric shaft gear 18 can push the movable frame 14 to slide inside the fixed frame 10, thereby realizing the push of the movable frame 14 on the crossbar 15, and then realizing the push of the crossbar 15 on the vertical bar 4.

[0026] Furthermore, the crossbar 15 is movably connected to the fixed frame 10 and the side wall in the middle of the outer casing 1 through the movable frame 14, so that the crossbar 15 can push the vertical bar 4 and the impact ball 5 to a position that fits against the surface of the hydrogen fuel cell, thereby realizing the impact of the impact ball 5 on the hydrogen fuel cell.

[0027] The usage method of this embodiment is as follows: When using this hydrogen fuel cell impact testing equipment, first connect the testing equipment to an external power source, then push the bottom end of the battery to be tested into the first slot 7 of the turntable 6 along the notch 9, and then insert the clip 8 into the first slot 7. At this time, the bottom end of the hydrogen fuel cell is fixed on the turntable 6. Next, the electric push rod 2 can be activated, causing the electric push rod 2 to push the pressure plate 3 against the top end of the hydrogen fuel cell, so that the top end of the hydrogen fuel cell is embedded in the second slot 19 at the bottom end of the pressure plate 3. Then, the first rotary motor 12 can be activated, causing the first rotary motor 12 to drive the rotating shaft 11 to rotate, causing the rotating shaft 11 to drive the first eccentric shaft gear 17 to rotate, causing the first eccentric shaft gear 17 to rotate. The second eccentric shaft gear 18 rotates, driving the movable frame 14 connected to the second eccentric shaft gear 18 to push the crossbar 15 to make linear reciprocating motion in the horizontal direction. At this time, the vertical bar 4 at the end of the crossbar 15 and the impact balls 5 at the top and bottom of the vertical bar 4 will simultaneously impact and collide with the surface of the horizontally rotating hydrogen fuel cell, simulating the accidental impact on the hydrogen fuel cell. Then, the second rotary motor 16 is started, causing the second rotary motor 16 to drive the turntable 6 to rotate, causing the turntable 6 to drive the hydrogen fuel cell and the pressure plate 3 to rotate in the horizontal direction. After the hydrogen fuel cell rotates to the set position, the hydrogen fuel cell is kept stationary, and then the impact balls 5 are started, so that different positions on the surface of the hydrogen fuel cell shell can be impact tested.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
