[0038] In the battery manufacturing process, it is often necessary to perform tests such as battery capacity assessment and testing to verify the integrity of the battery's charging and discharging functions and capacity, thereby selecting defective products for repair or scrapping. Battery testing fixtures and battery testing instruments are commonly used in these tests to ensure that the battery's various indicators meet standard requirements. Battery testing fixtures are mainly used to support and fix the battery to ensure its stability during testing. Currently, wiring harnesses are commonly used to connect the battery and testing instruments for testing the battery's electrical performance. To facilitate electrical connection between the battery and the testing instruments, battery testing fixtures are often equipped with probes. However, the current contact probe positions are fixed and may be inaccurate, thus potentially leading to errors in the test results. Furthermore, replacing damaged probes is inconvenient and time-consuming.
[0039] Based on this, please refer to Figure 1 , Figure 2 and Figure 3 The battery testing fixture 1000 provided in the embodiments of this utility model can effectively improve the technical problems mentioned above.

Both the first limiting plate 210 and the second limiting plate 220 are movably connected to the fixed plate 100 and can move relative to the fixed plate 100 along its length. The first limiting plate 210 and the second limiting plate 220 are used together to hold the battery 2000 to be tested. The detection component 300 includes a slider 310 and a probe 320, which are detachably connected to the slider 310. The slider 310 is detachably connected to the fixed plate 100 and can move relative to the fixed plate 100. The battery can be securely clamped by the first limiting plate 210 and the second limiting plate 220, ensuring its stability during testing. Furthermore, the first and second limiting plates 210 and 220 are movable relative to the fixed plate 100, allowing adjustment of the distance between them to accommodate batteries of different sizes and improving versatility. The sliding member 310 can move the probe 320, adjusting its position according to different batteries to ensure accurate contact between the probe 320 and the battery, reducing testing errors. Moreover, the sliding member 310 and the probe 320 are detachably connected to the fixed plate 100 and the sliding member 310, respectively, allowing for convenient and quick replacement of the probe 320 in case of damage, saving replacement time.
[0042] Please see Figures 1-3To facilitate disassembly and assembly and save installation and replacement time, the fixing plate 100 in this embodiment includes an upper cover plate 110 and a lower base plate 120, which are detachably connected. A portion of the first limiting plate 210 and a portion of the second limiting plate 220 are clamped between the upper cover plate 110 and the lower base plate 120. The upper cover plate 110 and the lower base plate 120 together clamp the sliding member 310, and the sliding member 310 can move relative to the upper cover plate 110 and the lower base plate 120. During installation, the first limiting plate 210 and the second limiting plate 220 are first connected to the lower base plate 120 respectively, and then the upper cover plate 110 is placed on top, connecting the upper cover plate 110 and the lower base plate 120. By configuring the fixing plate 100 into two detachable structures separated by an upper and lower partition, the installation of the first limiting plate 210 and the second limiting plate 220 can be facilitated, and the firmness and stability of the connection between the first limiting plate 210 and the second limiting plate 220 and the fixing plate 100 can also be ensured. In this embodiment, the upper cover plate 110 and the lower base plate 120 are detachably connected by threaded fasteners, which can be bolts, screws, etc., and are not limited here. Of course, the upper cover plate 110 and the lower base plate 120 can also adopt other detachable connection methods such as snap-fit or plug-in, and are not limited here.
[0043] Furthermore, to ensure the secure connection between the upper cover plate 110 and the lower base plate 120, the battery testing fixture 1000 in this embodiment also includes a side plate 800. The upper cover plate 110 and the lower base plate 120 are detachably connected via the side plate 800, that is, the upper cover plate 110 covers the lower base plate 120, the upper cover plate 110 and the side plate 800 are detachably connected, and the lower base plate 120 and the side plate 800 are detachably connected. In this embodiment, there are two side plates 800, with side plates 800 provided at both ends of the upper cover plate 110 and the lower base plate 120.
[0044] To facilitate the removal of the slider 310 and to ensure the smooth movement of the slider 310 relative to the fixed plate 100, please refer to [link / reference needed]. Figure 2 and Figure 3 and combined Figure 4 and Figure 6 , Figure 4 This is a schematic diagram of the upper cover from a first perspective provided in an embodiment of the present utility model; Figure 6This is a schematic diagram of the lower base plate 120 provided in an embodiment of the present invention. In this embodiment, the fixing plate 100 has a first sliding groove 111, and the sliding member 310 passes through the first sliding groove 111, allowing it to move within the first sliding groove 111. Specifically, in this embodiment, both the upper cover plate 110 and the lower base plate 120 have first sliding grooves 111, which penetrate both the upper cover plate 110 and the lower base plate 120. The sliding member 310 passes through the first sliding groove 111. When the probe 320 needs to be replaced, the sliding member 310 can be removed from the first sliding groove 111, and then the probe 320 can be quickly removed from the sliding member 310 for replacement. Alternatively, the sliding member 310 can also be slidably connected to the fixing plate 100 via a guide rail slider. The sliding member 310 and the slider are detachably connected, allowing for quick disassembly and replacement when the probe 320 is damaged.
[0045] Please see Figure 2 and Figure 3 and combined Figure 4 In this embodiment, the fixing plate 100 has multiple first fixing holes 112, which are spaced apart along the extending direction of the first sliding groove 111. The sliding member 310 is fixed to the fixing plate 100 through at least one first fixing hole 112. Specifically, threaded fasteners are used to pass through the first sliding groove 111 and at least one first fixing hole 112 to connect and fix the sliding member 310 and the fixing plate 100. By moving the sliding member 310, which is connected and fixed to the first fixing holes 112 at different positions through the threaded fasteners, the fixed position of the sliding member 310 relative to the fixing plate 100 can be changed, thereby changing the position of the probe 320. By providing the first fixing holes 112, when testing the battery, after the probe 320 reaches the designated position and contacts the battery, the sliding member 310 is prevented from moving again, changing the position of the probe 320, and thus affecting the accuracy of the test results. Of course, multiple first fixing holes 112 can be connected to form an adjustment hole. By moving the sliding member 310, the relative position between the first sliding groove 111 and the first fixing hole 112 can be changed, and then locked by threaded fasteners.
[0046] Furthermore, to make the movement of the first limiting plate 210 and the second limiting plate 220 relative to the fixed plate 100 smoother, the fixed plate 100 in this embodiment is provided with a second sliding groove 121 and a third sliding groove 122. The battery testing fixture 1000 also includes a first connecting member 400 and a second connecting member 500. The first connecting member 400 passes through the first limiting plate 210 and the second sliding groove 121 to connect the first limiting plate 210 and the fixed plate 100, and the first connecting member 400 can move along the second sliding groove 121. The second connecting member 500 passes through the second limiting plate 220 and the third sliding groove 122 to connect the second limiting plate 220 and the fixed plate 100, and the second connecting member 500 can move along the third sliding groove 122. Here, the first connecting member 400 and the second connecting member 500 are both threaded fasteners such as bolts and screws. Of course, the first limiting plate 210 and the second limiting plate 220 can also be slidably connected to the fixed plate 100 via a guide rail slider, which is not limited here.
[0047] To ensure the firmness and stability of the connection between the first limiting plate 210 and the second limiting plate 220 and the fixed plate 100, please refer to Figure 3 and combined Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the upper cover from a second perspective provided in an embodiment of the present invention. In this embodiment, the lower base plate 120 has a first groove 113 on the side facing the upper cover plate 110, and the upper cover plate 110 has a second groove 123 on the side facing the lower base plate 120. The first groove 113 and the second groove 123 are used together to place a portion of the first limiting plate 210 and a portion of the second limiting plate 220. That is, both portions of the first limiting plate 210 and the second limiting plate 220 are held in the first groove 113 and the second groove 123. At this time, the lower base plate 120 has a second sliding groove 121 and a third sliding groove 122. A portion of the first limiting plate 210 passes through the second sliding groove 121, and a portion of the second limiting plate 220 passes through the third sliding groove 122. The portions of the first limiting plate 210 and the second limiting plate 220 away from the lower base plate 120 are used to clamp and fix the battery 2000 to be tested.

The third limiting plate 610 and the fourth limiting plate 620 are spaced apart along the width direction of the fixed plate 100. Both the third limiting plate 610 and the fourth limiting plate 620 are movably connected to the fixed plate 100 and can move relative to the fixed plate 100 along the width direction of the fixed plate 100. The first limiting plate 210, the second limiting plate 220, the third limiting plate 610, and the fourth limiting plate 620 are used together to clamp the battery 2000 to be tested. By setting the third limiting plate 610 and the fourth limiting plate 620, the movement of the battery to be tested along the width direction can be restricted. Furthermore, the third limiting plate 610 and the fourth limiting plate 620 can also move relative to the fixed plate 100 in the width direction, and the distance between the third limiting plate 610 and the fourth limiting plate 620 can be adjusted to accommodate batteries of different sizes, thus improving versatility.

Alternatively, a first strip hole 611 and a second strip hole 621 can be formed on the fixing plate 100, multiple second fixing holes 114 can be formed on the third limiting plate 610, and multiple third fixing holes 115 can be formed on the fourth limiting plate 620. Of course, the third limiting plate 610 and / or the fourth limiting plate 620 can also be connected to the fixing plate 100 via other linear motion mechanisms such as guide rails or sliders. As long as the third limiting plate 610 and / or the fourth limiting plate 620 can move relative to the fixing plate 100, the structure of the third limiting plate 610, the fourth limiting plate 620, and the fixing plate 100 is not limited here.
[0050] To facilitate battery placement during battery installation in the battery testing fixture 1000, in this embodiment, the first limiting plate 210 has a first inclined plane 211 at its end away from the fixed plate 100, and the second limiting plate 220 has a second inclined plane 212 at its end away from the fixed plate 100; the angles between the first inclined plane 211 and the second inclined plane 212 and the vertical plane are both acute angles; and / or, the third limiting plate 610 has a third inclined plane 612 at its end away from the fixed plate 100, and the fourth limiting plate 620 has a fourth inclined plane 622 at its end away from the fixed plate 100; the angles between the third inclined plane 612 and the fourth inclined plane 622 and the vertical plane are both acute angles.
