[0024] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 ,in, Figure 1 This is a schematic diagram of the overall structure of the charge and discharge cycle detection device for multiple nickel-hydrogen batteries provided by the utility model; Figure 2This is a schematic diagram of the disassembled structure of the charge and discharge cycle detection device for multi-channel nickel-hydrogen batteries provided by the utility model; Figure 3 for Figure 2 The structural schematic diagram of the protective plate and reset assembly shown; Figure 4 for Figure 3 A schematic cross-sectional structure diagram of the protective plate shown; Figure 5 for Figure 3 The structural schematic diagram of the extrusion plate and the reset block shown; Figure 6 for Figure 3 The structural schematic diagram of the limit assembly is shown.

[0026] In the specific implementation process, Figure 1-Figure 6 As shown, a charge and discharge cycle detection device for a multi-channel nickel-hydrogen battery comprises a test device 1 for performing cycle detection on the nickel-hydrogen battery, a protective plate 2 is provided on one side of the test device 1, the protective plate 2 is engaged with the test device 1 through a plurality of limit assemblies, and a plurality of reset assemblies are provided inside the protective plate 2, the reset assemblies comprise a gripping member, an extrusion plate 3 and a reset block 4, a movable groove 5 and a limit groove 6 for the extrusion plate 3 and the reset block 4 to move are respectively provided inside the protective plate 2, and the movable groove 5 is communicated with the limit groove 6, one side of the extrusion plate 3 is connected to the inner side of the movable groove 5 through a plurality of elastic members, the reset block 4 is located inside the limit groove 6, and one end of the reset block 4 is fixedly connected to one end of the extrusion plate 3, and one end of the gripping member is fixedly connected to a side of the extrusion plate 3 away from the elastic member, when the extrusion plate 3 extrudes the engaging block 10, the reset block 4 does not contact the engaging block 10, so the extrusion plate 3 will not be stuck due to the reset block 4;

[0027] The elastic member is a reset spring 7, one end of the reset spring 7 is fixedly connected to one side of the extrusion plate 3, and the other end of the reset spring 7 is fixedly connected to the inner side of the movable groove 5. The holding member is a handle 8, and the handle 8 is concavely arranged, and the two ends of the handle 8 are respectively fixedly connected to the side of the extrusion plate 3 away from the elastic member. A mounting groove 9 matching the protective plate 2 is provided on one side of the test device 1. The limiting assembly includes a clamping block 10 and a limiting spring 11. A storage groove 12 matching the clamping block 10 is provided on the inner side of the mounting groove 9 opened in the test device 1, and one end of the clamping block 10 is located inside the storage groove 12, and one end of the limiting spring 11 is fixed to the clamping block 10 is fixedly connected at one end, and the other end of the limit spring 11 is fixedly connected to the inner side of the storage groove 12. Both ends of the protective plate 2 are provided with a card slot 13 matching the card block 10, and the card slot 13 is communicated with the movable groove 5. The two sides of the card block 10 away from the limit spring 11 are inclined. Because the handle 8 is concavely set, it can fit the contour of the palm more naturally when holding it, reducing the gap between the palm and the handle 8, making the grip more fitting and comfortable. At the same time, the concave setting can form a natural gripping space, which can make it easier for the palm to be placed firmly on the surface of the handle 8, and can provide better control.

[0028] When using the test equipment 1, it is necessary to place the nickel-hydrogen battery in the detection slot opened by the test equipment, and connect the detection line in the detection slot to the two ends of the nickel-hydrogen battery. After starting the test equipment 1, the specific data of the nickel-hydrogen battery is detected and collected through the detection line, and the safety status of the nickel-hydrogen battery is judged based on this data, thereby completing the detection of the nickel-hydrogen battery.

[0029] The working principle of the utility model is as follows: when it is necessary to replace the electronic components inside the test equipment 1, the handle 8 is pulled to drive the extrusion plate 3 and the reset block 4 to slide in the movable groove 5 and the limit groove 6 respectively, and the one side of the extrusion plate 3 is used to squeeze the one side of the locking block 10. Because the two sides of the locking block 10 away from the limit spring 11 are inclined, when one side of the extrusion plate 3 slides on the inclined surface of the locking plate, it will push the locking block 10 to move into the storage groove 12, and when the extrusion plate 3 is no longer in contact with the inclined surface of the locking block 10, the reset block 4 set at one end of the extrusion plate 3 will continue to push the locking block 10 to move into the storage groove 12, so that the locking block 10 is no longer in contact with the locking groove 13 opened on the protective plate 2, and the locking state between the protective plate 2 and the detection equipment is released, so that the protective plate 2 can be taken out from the installation groove 9 opened on one side of the detection equipment.

[0030] When installing the protective plate 2, the protective plate 2 is inserted into the installation groove 9 opened on one side of the detection device, and the inclined surface of the snap-fit ​​block 10 is squeezed by one side of the protective plate 2, so that the snap-fit ​​block 10 moves into the receiving groove 12 and squeezes the limit spring 11, so that one end of the snap-fit ​​block 10 can slide along one end of the protective plate 2. When one end of the snap-fit ​​block 10 slides to the position of the slot 13, the rebound force of the limit spring 11 drives the snap-fit ​​block 10 to move into the slot 13. Through the mutual cooperation between the snap-fit ​​block 10 and the slot 13, the protective plate 2 can be more firmly inserted into the installation groove 9;

[0031] Because the handle 8 is concave in shape, it can fit the contour of the palm more naturally when holding it, reducing the gap between the palm and the handle 8, making the grip more fitting and comfortable. At the same time, the concave setting can form a natural holding space, making it easier and more stable for the palm to be placed on the surface of the handle 8, and providing better control. It should be noted that when the extrusion plate 3 squeezes the locking block 10, the reset block 4 does not contact the locking block 10, so the extrusion plate 3 will not be stuck due to the reset block 4, and a fixing groove 14 for the handle 8 to move is provided on the surface of the protective plate 2.

[0032] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
