The described embodiments are some, but not all, of the embodiments of this utility model.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] Example 1: Please see the appendix Figure 1The battery DCIR testing mechanism 100 of this utility model includes a probe assembly 110 that movably contacts the two poles of the battery, and a probe adjustment assembly 120 connected to the probe assembly 110.

When the battery model is changed and it is necessary to adjust the spacing between the first probe unit 111 and the second probe unit 112, the spacing between the two probe units can be adjusted by sliding the first adjustment slider 1222 and the second adjustment slider 1223 on the adjustment slide rail 1221.

[0035] The battery DCIR testing mechanism 100 in this embodiment is assembled from a probe assembly 110 and a probe adjustment assembly 120. The probe adjustment assembly 120 can adjust the spacing and height of the probe assembly 110 so that the probe assembly 110 can be electrically connected to different types of batteries for DCIR testing.

[0036] Example 2: Please see the appendix Figure 3 The battery DCIR testing device of this utility model embodiment includes the battery DCIR testing mechanism 100 described in Embodiment 1, a test adjustment mechanism 200 connected to the battery DCIR testing mechanism 100, and a battery positioning mechanism 300 disposed adjacent to the battery DCIR testing mechanism 100.

Preferably, the test adjustment component 220 can be selected as a lead screw adjustment component or a slide rail slider adjustment component according to actual needs, as long as it can drive the battery DCIR test mechanism 100 closer to or further away from the battery for DCIR testing.

[0038] In this embodiment, the test adjustment component 220 is selected as a lead screw adjustment component; please refer to the appendix for further details. Figure 5The test adjustment assembly 220 includes an adjustment screw 221 mounted on the adjustment mechanism mounting bracket 210 and parallel to the first direction in its length direction; an adjustment mounting block 222 connected to the adjustment assembly mounting seat 121 in the battery DCIR test mechanism 100 and movably mounted on the adjustment screw 221; and an adjustment guide rod 223 passing through the adjustment mounting block 222 and parallel to the length direction of the adjustment screw 221 in its length direction. The adjustment screw 221 rotates to move the adjustment mounting block 222 along the first direction, thereby moving the battery DCIR test mechanism 100 mounted on the adjustment mounting block 222 along the first direction. The adjustment mounting block 222 is used to install and limit the overall position of the battery DCIR test mechanism 100. The adjustment guide rod 223 guides and corrects the movement of the adjustment mounting block 222 and the battery DCIR test mechanism 100 mounted thereon, improving the accuracy and stability of the overall adjustment of the battery DCIR test mechanism 100. Furthermore, the rotation of the adjusting screw 221 can be driven by a hand-cranked wheel or a rotary motor, and the specific selection and design can be made according to actual needs.

[0039] Please refer to the appendix for further details. Figure 4 In some embodiments, the battery positioning mechanism 300 includes a bottom positioning component 310 corresponding to the probe assembly 110 for positioning the bottom of the battery to be tested; and a side positioning component 320 adjacent to the probe assembly 110 for positioning and clamping the sides of the battery to be tested. Preferably, both the bottom positioning component 310 and the side positioning component 320 are adjustable positioning components to achieve positioning of different battery models and ensure stability during battery testing.

[0040] The battery DCIR testing device in this embodiment is formed by combining the battery DCIR testing mechanism 100, the testing adjustment mechanism 200, and the battery positioning mechanism 300 in Embodiment 1. It can not only effectively meet the testing needs of different battery models and improve the accuracy and efficiency of testing, but also effectively reduce the labor intensity of workers.

[0041] Example 3: Please see the appendix Figure 3 The battery DCIR testing device in this embodiment is the same as that in Embodiment 2, both including the battery DCIR testing mechanism 100 described in Embodiment 1, the testing adjustment mechanism 200 connected to the battery DCIR testing mechanism 100, and the battery positioning mechanism 300 disposed adjacent to the battery DCIR testing mechanism 100. The main difference is: The battery positioning mechanism 300 includes a bottom positioning component 310 corresponding to the probe assembly 110 for positioning the bottom of the battery to be tested; and a side positioning component 320 adjacent to the probe assembly 110 for positioning and clamping the sides of the battery to be tested. Preferably, both the bottom positioning component 310 and the side positioning component 320 are adjustable positioning components to achieve positioning of different battery models and ensure stability during battery testing.

[0042] Please refer to the appendix for further details. Figure 6 The bottom positioning assembly 310 includes a base plate 311 for overall assembly installation and device support, a first bottom positioning side plate unit 312 movably mounted on the base plate 311 for positioning the long side of the bottom of the battery, and a second bottom positioning side plate unit 313 movably mounted on the first bottom positioning side plate unit 312 for positioning the short side of the bottom of the battery. Preferably, both the first bottom positioning side plate unit 312 and the second bottom positioning side plate unit 313 include a bottom positioning side plate 3101 for positioning the bottom side of the battery, and a side plate adjustment mounting bolt 3102 passing through the bottom positioning side plate 3101 for adjusting the installation position of the bottom positioning side plate 3101.

The bakelite board has good insulation properties, which can effectively prevent short circuits during the test and thus ensure test safety; the fiberglass board has high mechanical strength and heat resistance, which can improve the overall load-bearing capacity and service life of the component.

[0044] When changing the battery model for DCIR testing, the bottom positioning side plate 3101 can be released by loosening the side plate adjustment mounting bolt 3102. Then, after moving the bottom positioning side plate 3101 to adapt to the positioning of different battery models, the side plate adjustment mounting bolt 3102 is tightened again to position the bottom of the battery during the test, ensuring the stability of the battery during the test and thus effectively improving the accuracy of the battery test.

[0045] Furthermore, the side positioning component 320 is a guide rod positioning component; please refer to the appendix for further details. Figure 7The side positioning assembly 320 includes a side positioning clamping block 321 disposed adjacent to the probe assembly 110 in the battery DCIR testing mechanism 100 for positioning and clamping the side of the battery to be tested; and a guide rod positioning adjustment unit 322 connected to the side positioning clamping block 321 for driving the side positioning clamping block 321 to position and clamp the side of the battery. Preferably, the guide rod positioning adjustment unit 322 includes a first positioning guide rod group 3221 arranged parallel to the first direction in length direction for adjusting the height of the side positioning clamping block 321; a second positioning guide rod group 3222 disposed on the first positioning guide rod group 3221 for adjusting the distance between the side positioning clamping block 321 and the side of the battery; and a third positioning guide rod group 3223 disposed on the second positioning guide rod group 3222 for fixing and installing the side positioning clamping block 321. The combination of the first positioning guide rod group 3221, the second positioning guide rod group 3222, and the third positioning guide rod group 3223 enables three-axis adjustment of the side positioning clamping block 321. Furthermore, to improve the efficiency of adjustment and testing, sensors and drive motors can be added to the first positioning guide rod group 3221, the second positioning guide rod group 3222, and the third positioning guide rod group 3223 to achieve position adjustment of the side positioning clamping block 321.

[0046] When it is necessary to position and clamp batteries of different models, the position of the side positioning clamping block 321 can be adjusted by the three-axis adjustment of the first positioning guide rod group 3221, the second positioning guide rod group 3222 and the third positioning guide rod group 3223, so as to position and clamp the side of batteries of different models and sizes.

[0047] The battery DCIR testing device in this embodiment combines the battery DCIR testing mechanism 100 from Embodiment 1 with the testing adjustment mechanism 200 and battery positioning mechanism 300 from Embodiment 2. This not only effectively meets the testing needs of different battery models, improving testing accuracy and efficiency, but also effectively reduces the labor intensity of workers.
