Description

Technical Field

[0001] The utility model relates to the field of new energy battery system testing, in particular to a multifunctional tray-type extruder testing platform used for new energy battery pack testing. Background Art

[0002] To ensure the safety of existing new energy battery packs in extreme environments where they may be squeezed after production, most manufacturers conduct special tests on new energy battery packs before launching them into the market. This involves simulating the squeezing conditions that the battery may encounter in actual use to assess the structural strength and safety of the battery and prevent safety accidents such as short circuits, fires or explosions.

[0003] In actual use, in some cases, extrusion tests will be carried out on new energy battery packs with heavier weight. During the corresponding extrusion test, it is generally necessary to use special lifting equipment to lift the battery pack onto the test platform, and the battery pack must be adjusted to the corresponding position of the test platform with the assistance of on-site personnel. The existing battery packs produced by different manufacturers are more or less different. However, if the battery pack produced has an irregular shape, when it is placed on the test platform, due to the irregular shape of the battery pack, when the extrusion head applies a little pressure during the extrusion test, the battery pack will deflect, which will lead to inaccurate test results of the battery pack. In order to avoid this situation, the test platform often needs to be matched with corresponding auxiliary tooling for fixing the battery pack.

[0004] In addition, in actual implementation, in order to adapt to the compression test of heavier battery packs, the following situations are often encountered: 1. When special lifting equipment is involved at the test site, it is necessary to invest funds to build it, and there are certain requirements for the floor height and area of ​​the factory building. In other words, when the factory building conditions are insufficient, it is impossible to install special lifting equipment, making it difficult to conduct the compression test of heavy battery packs;

[0005] 2. When using dedicated lifting equipment to adjust the position of the battery pack on the test platform, after the dedicated lifting equipment is lifted, on-site personnel are generally required to assist in adjusting the position. During this adjustment process, its accuracy is difficult to control and it often requires multiple adjustments. This also makes the adjustment process time-consuming and labor-intensive. Even after the adjustment is completed, there will be certain risks to on-site personnel when lowering the battery pack.

[0006] 3. When using auxiliary tooling to fix the battery pack, additional tooling needs to be customized separately, and the tooling needs to be fixed on the test platform, which is time-consuming and labor-intensive, and the test efficiency is low. Summary of the Invention

[0007] In view of the above-mentioned deficiencies, the present invention provides a multifunctional tray-type extruder testing platform for new energy battery packs, which does not require special lifting equipment and can achieve highly reliable placement of new energy battery packs to be tested.

[0008] In order to achieve the above objectives, the utility model adopts a multifunctional tray-type extruder test platform for new energy battery packs, including an extrusion platform, an extrusion mechanism, and an extrusion back wall. The extrusion platform includes an extrusion test side and an extrusion limit side for limiting the extrusion of the battery pack. The extrusion mechanism is limited to one side of the extrusion test side, and the extrusion back wall is limited to one side of the extrusion limit side.

[0009] The extrusion mechanism includes a limit seat, an extrusion head connected to the limit seat and capable of performing an extrusion action toward the test platform, and an extrusion power source for driving the extrusion head. The test platform is characterized in that: the test platform also includes a tray for placing an external battery pack and a pressing member, and the tray is provided with a fork insertion port for inserting a fork on an external forklift;

[0010] During the test phase of the external battery pack to be tested, it is first placed on a pallet, and the fork on the external forklift is inserted into the fork insertion port, and the external forklift is moved to move the pallet and the external battery pack to be tested to the extrusion platform, and the pressing part bypasses the external battery to be tested and passes through the pallet to form a limit on the extrusion platform, and the external battery pack to be tested is placed on the extrusion platform to perform the limit before the test.

[0011] The utility model is further configured such that a plurality of universal rollers are provided on the upper limit of the pallet, which are moved to the pallet and the external battery pack to be tested on the extrusion platform by an external forklift, and the plurality of universal rollers on the pallet are all oriented toward the extrusion platform and in contact with the extrusion platform, and an external force is applied to the pallet, so that the pallet rolls on the extrusion platform via the plurality of universal rollers, thereby precisely adjusting the position of the external battery pack to be tested on the extrusion platform; the plurality of universal rollers are all universal balls.

[0012] The present invention is further configured such that a hollow avoidance groove is provided on the tray. During the test phase of the external battery pack to be tested, the extrusion head of the extrusion mechanism passes through the hollow avoidance groove, so that the extrusion head performs an extrusion action on the external battery pack to be tested in the direction of the extrusion back wall; through the above, the extrusion test of the battery pack can be reliably carried out, which avoids the problem that after the tray is involved, the extrusion platform and the extrusion mechanism are both existing settings, that is, the existing extrusion mechanism can realize reliable testing of the battery pack when the tray is not involved, and after the tray is involved, due to the fixation of the battery pack involved in the present invention, a tray is placed under the battery pack, and by opening the hollow avoidance groove, the extrusion test of the battery pack can be realized, which is not affected by the design of the tray, thereby ensuring the reliable implementation of the extrusion test of the battery pack.

[0013] The present invention is further configured such that the test platform also includes a water pool, and the extrusion platform includes a lifting platform and a lifting mechanism. One end of the lifting mechanism extends into and is connected to the bottom of the water pool, and the other end is connected to the lifting platform. During the fire stage of the test of the external battery pack, the lifting mechanism performs a lifting action, so that the lifting platform and the external battery pack are sunk into the water pool together.

[0014] The utility model is further configured such that the test platform also includes a tray limiting member for passing through the tray and extending toward the lifting platform, the clamping member includes a plurality of pressure strips pressed onto the external battery pack, and a battery pack limiting member for passing through the pressure strips and the tray and bypassing the external battery pack and extending toward the lifting platform, the tray is also provided with a plurality of limiting holes, which are connected to the limiting holes by the tray limiting member to form a limit on the lifting platform, and are connected to the limiting holes by the battery pack limiting member to form a limit on the tray and the external battery on the lifting platform.

[0015] The utility model is further configured such that the hollow avoidance grooves are respectively opened on the extrusion test side and the extrusion limit side of the pallet and are symmetrically distributed; the fork insertion opening on the pallet is vertically distributed to the hollow avoidance grooves.

[0016] Compared with the prior art, the beneficial effect of the present invention is that, in addition to the extrusion platform, the extrusion mechanism, and the extrusion back wall, the extrusion press test platform also involves a pallet and a pressing member for pressing the battery pack, and synchronously involves a fork insertion port on the pallet. Therefore, when the new energy battery pack needs to be tested, the on-site personnel can first place the battery pack on the pallet by moving or lifting it, and then insert the fork of the forklift into the fork insertion port on the pallet. Then, the pallet with the battery pack is moved to the extrusion platform by the movement of the forklift, and then the battery pack is fixed to the extrusion platform together with the pallet by the action of the pressing member, thereby completing the placement of the battery pack on the extrusion platform and convenient positioning. Compared with the existing design that can eliminate the need for special lifting equipment, the battery pack test involved in the present invention is not restricted by the floor height or factory infrastructure of the factory, thereby realizing that the vast majority of existing manufacturers can perform the required extrusion test on their own after producing heavier new energy battery packs, thereby greatly improving the convenience and adaptability of the new energy battery pack extrusion test.

[0017] In addition, by installing several universal rollers on the pallet, when the pallet together with the new energy battery pack is moved to the extrusion platform by a forklift, the universal rollers can be used to conveniently adjust the position of the new energy battery pack after it is placed on the extrusion platform. Compared with the existing method of fixing the battery pack, which requires independent auxiliary tooling, it can achieve convenient fixation of the battery pack, thereby greatly improving the efficiency of installation before testing.

[0027] like Figure 1-9 As shown, the specific embodiment of the present invention is a multifunctional tray-type extruder test platform for new energy battery packs, including an extrusion platform, an extrusion mechanism, and an extrusion back wall 6. The extrusion platform includes an extrusion test side 74 and an extrusion limit side 75 for limiting the extrusion of the battery pack a. The extrusion mechanism is limited to one side of the extrusion test side 74, and the extrusion back wall 6 is limited to one side of the extrusion limit side 75.

[0028] The extrusion mechanism includes a limit seat, an extrusion head 4 connected to the limit seat and capable of performing an extrusion action toward the test platform, and an extrusion power source 3 for driving the extrusion head 4. The test platform also includes a tray 7 for placing an external battery pack a and a clamping member. The tray 7 is provided with a fork insertion port 71 for inserting a fork from an external forklift.

[0029] During the test phase, the external battery pack a is first placed on the pallet 7 and inserted into the fork insertion port 71 by the fork on the external forklift. The external forklift moves the pallet 7 and the external battery pack a to be tested to the extrusion platform, and the pallet 7 is moved to bypass the external battery pack a through the clamping member and pass through the pallet 7 to form a limit on the extrusion platform, thereby forming the external battery pack a on the extrusion platform and performing the limit before the test.

[0030] like Figure 6 As shown, the upper limit of the tray 7 is provided with a plurality of universal rollers 72, which are moved to the tray 7 and the external battery pack a to be tested on the extrusion platform by an external forklift. The plurality of universal rollers 72 on the tray 7 are all facing the extrusion platform and in contact with the extrusion platform. When an external force is applied to the tray 7, the tray 7 is rolled on the extrusion platform by the plurality of universal rollers 72, thereby precisely adjusting the position of the external battery pack a to be tested on the extrusion platform; the plurality of universal rollers 72 are all universal balls.

[0031] like Figure 6As shown, the tray 7 is further provided with a hollow avoidance groove 73. During the testing phase of the external battery pack a to be tested, the extrusion head 4 of the extrusion mechanism passes through the hollow avoidance groove 73, so that the extrusion head 4 performs an extrusion action on the external battery pack a to be tested toward the extrusion back wall 6; the hollow avoidance grooves 73 are respectively opened on the extrusion test side 74 and the extrusion limit side 75 of the tray 7 and are symmetrically distributed; the fork insertion port 71 on the tray 7 is vertically distributed to the hollow avoidance grooves 73.

[0032] like Figure 1-5 As shown, the test platform also includes a water pool 1, and the extrusion platform includes a lifting platform 2 and a lifting mechanism 5. One end of the lifting mechanism 5 extends into and is connected to the bottom of the water pool 1, and the other end is connected to the lifting platform 2. During the fire stage of the test of the external battery pack a, the lifting mechanism 5 performs a lifting action, so that the lifting platform 2 and the external battery pack a are sunk into the water pool 1 together.

[0033] like Figure 1-3 As shown in Figures 8-9, the above-mentioned test platform also includes a tray limiter 10 for passing through the tray 7 and extending to the lifting platform 2. The clamping member includes a plurality of pressure strips 8 pressed on the external battery pack a, and a battery pack limiter 9 for passing through the pressure strips 8, the tray 7, bypassing the external battery pack a and extending to the lifting platform 2. A plurality of limit holes 21 are also provided on the tray 7. The tray limiter 10 is connected to the limit hole 21 to form a limit on the tray 7 on the lifting platform 2. The battery pack limiter 9 is connected to the limit hole 21 to form a limit on the tray 7 and the external battery on the lifting platform 2. The preferred design scheme of the tray limiter 10 is a short screw, and the preferred design scheme of the battery pack limiter 9 is a long screw. The preferred design of the synchronous limiter 21 is a threaded hole that cooperates with the long screw or the short screw.

[0034] In addition to the extrusion platform, extrusion mechanism, and extrusion back wall 6, the extrusion press test platform also includes a pallet 7 and a pressing member for pressing the battery pack a. Simultaneously, a fork insertion port 71 is provided on the pallet 7. Therefore, when the new energy battery pack a needs to be tested, the on-site personnel can first place the battery pack a on the pallet 7 by moving or lifting it, and then insert the fork of the forklift into the fork insertion port 71 on the pallet 7. Then, the pallet 7 with the battery pack a is moved to the extrusion platform by the movement of the forklift. Then, the battery pack a is fixed to the extrusion platform together with the pallet 7 by the action of the pressing member, thereby completing the placement of the battery pack a on the extrusion platform and conveniently limiting its position. Compared with the existing design that can eliminate the need for special lifting equipment, the test of the battery pack a involved in the utility model is not restricted by the height of the factory floor or the factory infrastructure, thereby realizing that most existing manufacturers can perform the required extrusion test on their own after producing the heavier new energy battery pack a, thereby greatly improving the convenience and adaptability of the extrusion test of the new energy battery pack a.

[0035] In addition, by arranging several universal rollers 72 on the pallet 7, when the pallet 7 together with the new energy battery pack a is synchronously moved to the extrusion platform by a forklift, the universal rollers 72 can be used to conveniently adjust the position of the new energy battery pack a after it is placed on the extrusion platform. Compared with the existing method of fixing the battery pack a which requires independent auxiliary tooling, the method can conveniently fix the battery pack a, thereby greatly improving the efficiency of installation before testing.

[0036] The utility model relates to a multifunctional tray 7-type extruder test platform for new energy battery packs in the specific implementation process: 1. After the tray 7 body is formed, a rollable universal ball is installed to form a multifunctional tray 7; 2. The battery pack a is transferred to the tray 7 by a forklift or other transport tool, and the non-extrusion side of the tray 7 is flush with one side of the multifunctional tray 7; 3. The forklift is inserted into the forklift insertion port of the tray 7, and the tray 7 and the battery pack a are directly placed on the lifting platform 2, and the upper and lower positions of the lifting platform are adjusted; 4. Since the bottom of the tray 7 has universal wheels, the friction with the lifting platform 2 is small, and the tray 7 is manually adjusted on the extrusion platform. 5. After the test starts, the extrusion head 4 is driven by the extrusion power source 3 to extrude the battery pack a. As the extrusion head 4 invades, the battery pack a is deformed, and the pallet 7 avoids the extrusion head 4 to prevent it from affecting the test. 6. After waiting for a certain period of time as required and ensuring safety, the lifting platform 2 is raised, the fixed long and short screws are removed, and the pallet 7 with the battery pack a is taken out by a forklift. After it is placed in the specified area and transported to other pallets 7, the entire test is completed and the pallet 7 can be reused.
