Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically to a device for testing the electrical performance of a soft-pack battery. Background Technology

[0002] Pouch batteries typically refer to batteries encapsulated in an aluminum-plastic composite film casing. They offer advantages such as light weight, lower molding costs, and higher safety. Performance testing of pouch batteries is conducted using appropriate electrical performance testing equipment. Currently, existing pouch battery testing methods involve laying the battery flat, which is inconvenient for clamping the battery's ends during testing. Utility Model Content

[0003] To address the above problems, the technical solution adopted by this utility model is as follows:

[0004] A device for testing the electrical performance of a pouch battery includes a support structure. The support structure includes a plurality of positioning components and an adjustment component. The positioning component includes a placement block and a limiting groove. An inclined limiting groove is provided on the inner side of the placement block. The limiting groove is used to place the pouch battery to be tested. The adjustment component is disposed at the opposite end of the positioning component. The adjustment component is used to adjust the distance between the plurality of positioning components to correspond with the pouch battery.

[0005] This invention relates to a device for testing the electrical performance of a soft-pack battery. By designing an inclined limiting groove, the device enables the soft-pack battery to be placed at an angle, thus solving the problem of inconvenient clamping and testing at the end of the soft-pack battery when it is laid flat.

[0006] Furthermore, the support assembly also includes an inclined support block, which is disposed at the bottom inner side of the placement block.

[0007] This invention enhances the stability of the soft-pack battery by simultaneously setting a limiting groove and a support block in the positioning component, and further strengthening the support of the soft-pack battery through the support block. Compared with separately designed limiting grooves or other support structures, the stability of the soft-pack battery is enhanced.

[0008] Furthermore, both the limiting groove and the support block are provided with silicone or sponge pads.

[0009] This invention achieves a buffering effect on the limiting groove and the support block by arranging silicone or sponge pads on the limiting groove and the support block.

[0010] Furthermore, the inclination of the support block is consistent with the inclination of the limiting groove.

[0011] In this invention, the overall tilt of the support block is consistent with the tilt of the limiting groove, which enables the soft-pack battery to be placed stably and ensures that the placed soft-pack battery maintains a consistent tilt.

[0012] Furthermore, the adjustment assembly includes a connecting block, a double-ended screw, a fixing block, and a rotating handle. One end of the double-ended screw is rotatably connected to the rotating handle and passes through and connects the fixing block and the connecting block.

[0013] This invention, by setting up a connecting block, a double-ended screw, a fixing block, and a rotating handle, can adjust the distance between two placement blocks to achieve clamping suitable for soft-pack batteries of different widths.

[0014] Furthermore, the adjustment component also includes a limiting strip and a slider. The limiting strip is disposed at the rear end of the fixed block and is fixedly connected to the fixed block; the slider is disposed at the rear end of the connecting block and is fixedly connected to the connecting block.

[0015] Furthermore, the inner side of the limiting strip is provided with a sliding groove, and the sliding groove is slidably connected to the slider.

[0016] This invention uses limit bars and sliders to limit the movement of the placement block, thus ensuring stable movement of the placement block.

[0017] Furthermore, the device also includes a worktable, a battery detector body and a track arranged above the worktable, a plurality of terminal blocks being slidably connected on the track, and a support structure being arranged opposite to the track.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model, by setting up a placement block, a limiting groove, a sponge pad, and a support block, tilts the soft-pack battery to be tested, so that the testing end of the soft-pack battery tilts upward, making it easier to connect with the testing clip, thus solving the problem of inconvenience in clamping and testing the end of the soft-pack battery when it is laid flat.

[0020] 2. This utility model, by setting a connecting block, a double-headed screw, a fixing block and a rotating handle, enables the adjustment of the distance between the two placement blocks, thereby achieving clamping suitable for soft-pack batteries of different widths.

[0021] 3. This utility model uses limit bars and sliders to limit the movement of the placement block, thus ensuring stable movement of the placement block. Attached Figure Description

[0027] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] like Figure 1 As shown, the present invention proposes a soft-pack battery electrical performance testing device, including a worktable 1, a battery detector body 2 and a track 3 respectively arranged on the worktable 1, and a plurality of terminal blocks 4 arranged on the track 3, the terminal blocks 4 being slidably connected above the track 3. The soft-pack battery electrical performance testing device also includes a support structure 5, which is arranged opposite to the track 3 and located at the front end of the worktable 1.

[0030] like Figure 2 As shown, the support structure 5 includes a positioning component 501 and an adjustment component 502; the positioning component 501 and the adjustment component 502 are arranged on the top front side of the worktable 1.

[0031] like Figure 3As shown, the positioning component 501 includes a placement block 5011, with a groove on its inner side. In this embodiment, two placement blocks 5011 are provided, symmetrically arranged on the worktable 1. The inner grooves of the two placement blocks 5011 are respectively provided with limiting grooves 5012 that cooperate with the soft-pack battery. The limiting grooves 5012 are inclined, with the lower end facing the inner side of the groove in the placement block 5011, and the higher end facing the outer side of the groove. The overall structure of the limiting grooves is a cuboid design, which allows for better contact with the soft-pack battery, reducing damage to the battery cell when supporting it. Furthermore, a sponge pad A5013 is attached to the bottom inner wall of the limiting groove 5012, providing cushioning when the soft-pack battery contacts the sponge pad A5013, preventing damage during placement.

[0032] Furthermore, to enhance the support for the placed soft-pack battery, a support block 5014 can be provided at the bottom of the inner groove of the placement block 5011 in this embodiment. The overall inclination of the support block 5014 is consistent with the inclination of the limiting groove 5012. The lower end of the support block 5014 faces the inner side of the groove in the placement block 5011, and the higher end faces the outer side of the groove. The support block 5014 has a roughly rectangular shape. Simultaneously, a sponge pad B5015 is attached to the top side of the support block 5014, aligned with the sponge pad A5013. Besides the sponge pad material, the aforementioned cushioning material can also be silicone. Other supporting materials that can provide the same cushioning effect can replace the sponge pad or silicone material mentioned in this embodiment.

[0033] This utility model, by setting up a placement block 5011, a limiting groove 5012, a sponge pad A 5013, a support block 5014, and a sponge pad B 5015, enables the soft-pack battery to be placed at an angle, so that the testing end of the soft-pack battery is tilted upwards, which facilitates connection with the testing clip and solves the problem that it is inconvenient to clamp and test the end of the soft-pack battery when it is laid flat.

[0034] like Figure 4As shown, the adjustment assembly 502 includes two connecting blocks 5024, a double-ended screw 5022, two fixing blocks 5021, and a rotating handle 5023. One end of the double-ended screw 5022 is rotatably connected to the rotating handle 5023 and rotatably connected to one of the through fixing blocks 5021 via a rotating shaft. Then, it sequentially threads through the two connecting blocks 5024. The other end of the double-ended screw 5022 passes through the other fixing block 5021 and is rotatably connected to it. In this embodiment, the two connecting blocks 5024 are located at the rear ends of the two placement blocks 5011 and correspond to their positions. The two fixing blocks 5021 are symmetrically arranged on the worktable 1.

[0035] In this embodiment of the utility model, such as Figure 4 As shown, the adjustment assembly 502 also includes a limiting strip 5026 and a slider 5025; the two ends of the limiting strip 5026 are respectively fixedly connected to the rear ends of two fixed blocks 5021, and the two sliders 5025 are respectively fixedly connected to the rear ends of two connecting blocks 5024; wherein, a sliding groove 5027 is provided on the inner side of the limiting strip 5026, and the slider 5025 slides in cooperation with the sliding groove 5027.

[0036] This utility model, by setting a limiting strip 5026 and a slider 5025, has the advantage of limiting the movement of the placement block 5011, so that the movement of the placement block 5011 remains stable.

[0037] The working principle of the aforementioned adjustment component 502 is as follows: Based on the width of the pouch battery, rotating the handle 5023 causes the double-ended screw 5022 to rotate, moving the two connecting blocks 5024 relative to or away from each other. This causes the two placement blocks 5011 to move relative to or away from each other, and the slider 5025 to move along the slide groove 5027 until the distance between the two placement blocks 5011 corresponds to the pouch battery. The pouch battery is then inserted at an angle between the two placement blocks 5011, with its side end correspondingly inserted into the limiting groove 5012. The pouch battery is placed at an angle, and the detection clamp of the detection device aligns with the detection end of the pouch battery. In this practical embodiment, the aforementioned adjustment component 502 can adjust the distance between the two placement blocks 5011, offering the advantage of being suitable for pouch batteries of different widths.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
