Description

Technical Field

[0001] This utility model relates to the field of battery accessories technology, specifically to a test device for the elasticity of a side-fitting frame. Background Technology

[0002] The vibration resistance of heavy-duty automotive batteries is a major factor affecting their service life. Currently, the most effective means to improve vibration resistance are to cast hot melt adhesive and install plug brackets to ensure that the electrode groups are tightly assembled within each cell.

[0003] The principle of the edge-fitting bracket is to utilize the elasticity of the bracket material itself and its designed elastic structure. Under pressure, the thickness changes, allowing the electrode groups to adjust within a certain range in the thickness direction to achieve a tight fit. Different electrode group thicknesses result in different assembly pressures after insertion into the slot. Thicker electrode groups require higher assembly pressure, potentially causing the edge-fitting bracket to break during insertion; thinner electrode groups exceed the adjustment range of the edge-fitting bracket, failing to achieve a tight fit. Therefore, each battery model requires a different edge-fitting bracket. Although there are currently many types and sizes of edge-fitting brackets available, a simple and effective method is still lacking for selecting the appropriate edge-fitting bracket for a specific battery model.

[0004] Therefore, how to provide a test device for the elasticity of the edge-sealing frame is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a side-mounted frame elasticity testing device, which can detect the elasticity adjustment range of the side-mounted frame, and at the same time screen out the side-mounted frames that are compatible with the battery cells, so as to avoid the problem of unreasonable electrode group assembly caused by the unsuitability of the side-mounted frame.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a test device for the elasticity of a side-fitting frame, comprising:

[0007] The base has upright plates fixed at both ends, a side plate at one side end, and a scale fixed at the top of the side plate.

[0008] A pressure sensor is located between two vertical plates and is fixedly connected to one end of the vertical plate. A pressure measuring plate is fixed on the pressure sensor.

[0009] A sliding pressure plate is arranged parallel to the pressure measuring plate. An adjusting rod is rotatably connected to one end of the sliding pressure plate away from the pressure measuring plate. The adjusting rod is threadedly connected to the vertical plate at the other end. An electrode group and a side-fitting frame are placed between the sliding pressure plate and the pressure measuring plate. The distance between the sliding pressure plate and the pressure measuring plate is obtained with reference to a scale.

[0010] The beneficial effects of this utility model are as follows: a beaded frame and an electrode group are placed between the pressure measuring plate and the sliding pressure plate. The beaded frame is squeezed by reducing the distance between the pressure measuring plate and the sliding pressure plate until the beaded frame is damaged. At this time, the reduced distance between the pressure measuring plate and the sliding pressure plate is the elastic adjustment range of the beaded frame. At the same time, a pressure sensor can be used to detect the maximum pressure that the beaded frame can withstand. The reduced distance between the pressure measuring plate and the sliding pressure plate is measured with a ruler, which is convenient to use.

[0011] Preferably, a pressure gauge is fixedly connected to the side plate, and the pressure gauge is electrically connected to a pressure sensor.

[0012] The resulting technical effect is that the pressure gauge can directly obtain the test value of the pressure sensor, thereby obtaining the bearing pressure of the object under test.

[0013] Preferably, the bottom surface of the sliding pressure plate is slidably connected to the top surface of the base, and a transition sleeve is provided on the side of the sliding pressure plate away from the pressure measuring plate. A connector is rotatably connected inside the transition sleeve, and the connector is fixed to the end of the adjusting rod.

[0014] The resulting technical effect is that the sliding pressure plate can move smoothly laterally, and the sliding pressure plate is moved by adjusting the thread of the adjusting rod, thereby achieving the predetermined squeezing effect. The connector ensures that the rotation of the adjusting rod will not produce axial displacement within the transition sleeve.

[0015] Preferably, the adjusting rod has a threaded section, and a threaded hole is opened on the vertical plate at the end away from the pressure sensor. The adjusting rod is threaded into the threaded hole, and an operating handle is fixed at the end of the adjusting rod away from the connector. A locking nut is provided on the threaded section of the adjusting rod.

[0016] The resulting technical effects are: the threaded section and the threaded hole enable changes in axial displacement; the operating handle facilitates the rotation of the adjusting rod; and the locking nut locks the adjusting rod in place on the vertical plate, preventing the adjusting rod from rotating arbitrarily.

[0017] Preferably, one end of both the sliding pressure plate and the pressure measuring plate is close to the scale.

[0018] The resulting technical effect is that both the sliding pressure plate and the pressure measuring plate are close to the scale on one side, which facilitates parameter acquisition and obtains accurate measurement data. Attached Figure Description

[0021] 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 protection scope of the present utility model.

[0022] See appendix to this utility model Figure 1 According to an embodiment of the present invention, a test device for the elasticity of a gusseted frame includes:

[0023] A base 1 has upright plates 2 fixed at both ends of the base 1. A side plate 3 is provided on one side of the base 1. Both ends of the side plate extend to the upright plate and are fixed thereto. A scale 4 is fixed to the top of the side plate 3.

[0024] Pressure sensor 5 is located between two vertical plates and is fixed to one end of vertical plate 2. Pressure measuring plate 6 is fixed on pressure sensor 5.

[0025] A sliding pressure plate 7 is arranged parallel to the pressure measuring plate 6. An adjusting rod 8 is rotatably connected to the end of the sliding pressure plate 7 away from the pressure measuring plate 6. The adjusting rod 8 is threadedly connected to the vertical plate at the other end. An electrode group 9 and a side-fitting bracket 10 are placed between the sliding pressure plate 7 and the pressure measuring plate 6. The distance between the sliding pressure plate 7 and the pressure measuring plate 6 is obtained with reference to a scale.

[0026] The elastic adjustment range of the edge clamp is achieved by following these steps:

[0027] Before the test begins, place the sliding pressure plate against the pressure measuring plate, ensuring that the pressure value of the pressure measuring plate is zero, and record the scale dimension of the sliding pressure plate.

[0028] Adjust the distance between the sliding pressure plate and the pressure test using the operating handle until the pole group and the edge holder can be loosely placed within it;

[0029] Slowly crank the operating handle to reduce the distance between the sliding pressure plate and the pressure measuring plate until the pressure gauge starts to display a reading. Record the scale reading H1 at this time.

[0030] Continue to slowly crank the operating handle to reduce the distance between the sliding pressure plate and the pressure measuring plate until the edge bracket is damaged. Record the pressure gauge reading P and the scale reading H2 at this time.

[0031] The difference between H1 and H2 is the elastic adjustment range of the edge-fitting frame, and P is the maximum pressure that the edge-fitting frame can withstand.

[0032] In some other embodiments, a pressure gauge 11 is fixedly connected to the side plate 3. The pressure gauge 11 is electrically connected to the pressure sensor 5, and the pressure gauge can directly obtain the detected pressure value.

[0033] In some other specific embodiments, the bottom surface of the sliding pressure plate 7 is slidably connected to the top surface of the base 1, and a transition sleeve 12 is provided on the side of the sliding pressure plate 7 away from the pressure measuring plate 6. A connector is rotatably connected inside the transition sleeve 12, and the connector is fixed to the end of the adjusting rod 8.

[0034] The rotation of the adjusting rod will only push the sliding pressure plate; the sliding pressure plate will not rotate.

[0035] In some other embodiments, the adjusting rod 8 has a threaded section, and a screw hole is opened on the vertical plate 2 at the end away from the pressure sensor 5. The adjusting rod 8 is threaded into the screw hole. An operating handle 14 is fixed at the end of the adjusting rod 8 away from the connector. A locking nut 13 is provided on the threaded section of the adjusting rod 8. The locking nut can lock the position of the adjusting rod. The locking nut abuts against the vertical plate.

[0036] In some other specific embodiments, one side of the sliding pressure plate 7 and the pressure measuring plate 6 are close to the scale 4, which facilitates the accurate acquisition of the position and size of the sliding pressure plate and the pressure side plate.

[0037] This utility model also discloses a method for screening battery plug holders using the above-mentioned testing device, which includes the following steps:

[0038] Step 1: Obtain the internal width of the battery cell to be used in the edge bracket, denoted as W;

[0039] Step 2: Add a certain number of thin plates to the cell from Step 1 until the cell deforms. This deformation can be understood as the critical state of cell deformation.

[0040] Step 3: Take out all the thin plates from Step 2 and place them between the sliding pressure plate and the pressure measuring plate of the testing device. Adjust the distance between the sliding pressure plate and the pressure measuring plate until the width is W. Record the pressure at this time as P. This pressure is the pressure value before the deformation of the single cell in the early stage.

[0041] Step 4: Assemble the electrode group with the thinnest electrode group among the battery models to be assembled into a component, place it between the sliding pressure plate and the pressure measuring plate of the testing device, and record the component width W0 when the pressure is zero.

[0042] Step 5: Compare the values ​​of W0 and W. If W0 < W, it means that the thickness of this edge bracket is not enough and the assembly will not achieve the purpose of tight assembly of individual compartments. A thicker edge bracket needs to be replaced. Repeat Step 4 until W0 > W.

[0043] Step Six: Slowly increase the pressure on the component by sliding the pressure plate until the edge frame breaks. Record the pressure P0 and the component width reading W1 at this time. If P0 > P, the difference between W0 and W1 is the maximum elastic adjustment range of the edge frame. Proceed to the next step. If P0 < P, it means that the compressive strength of this edge frame is insufficient and a new type of edge frame needs to be replaced. Return to Step Four until P0 > P.

[0044] Step 7: Place the thinnest electrode group of the battery model to be assembled between the sliding pressure plate and the pressure measuring plate of the testing device, slowly increase the pressure to P0, and record the electrode group width reading W2 at this time;

[0045] Step 8: Place the thickest electrode group of the battery model to be assembled between the sliding pressure plate and the pressure measuring plate of the testing device, slowly increase the pressure to P0, and record the electrode group width reading W3 at this time;

[0046] Step 9: If the difference between W0 and W1 is greater than the difference between W3 and W2, then select a suitable edge trimmer; if the difference between W0 and W1 is less than the difference between W3 and W2, return to step 4 and start again until the difference between W0 and W1 is greater than the difference between W3 and W2.

[0047] In practical use, first measure the internal width of a single cell and fill it with a certain number of thin plates until deformation occurs. This number of thin plates will inevitably exert a certain pressure on the side wall of the single cell, which is equal to P in step three. Assemble the smallest thin plate of this model with the edge-fitting frame into a component. If the width of the component does not reach the internal width of the single cell, it proves that the edge-fitting frame is too small and unsuitable. If it is larger than the internal width of the single cell, the next step of edge-fitting frame compression resistance test needs to be carried out. Since a certain number of thin plates exert pressure on the single cell in the early stage, this pressure value is compared with the pressure value when the edge-fitting frame is damaged. If the pressure value when the edge-fitting frame is damaged is less than the pressure of the single cell filled with thin plates in the early stage, it proves that the edge-fitting frame is not strong enough and continues to be replaced until the compression resistance meets the requirements. At the same time, it is also necessary to consider that the deformation of the edge-fitting frame is greater than the deformation of the electrode group, and finally obtain a suitable edge-fitting frame.

[0048] This invention can select suitable edge-fitting frames to accommodate different models of battery cells.
