Description

Technical Field

[0001] The utility model relates to the technical field of vehicle battery installation simulation devices, in particular to vehicle battery installation simulation tooling and a vehicle battery installation simulation system. Background Art

[0002] As an energy supply unit, the battery pack is used in various energy-requiring devices such as vehicles. Specifically, the battery pack is usually installed under the chassis. Once the battery pack has a thermal runaway, smoke will be ejected from the explosion-proof valve located under the chassis. In order to improve the safety of the entire vehicle, a thermal runaway test of the battery pack is required. The simulation tooling is required to roughly imitate the working environment of the battery pack. During the thermal runaway test, the battery pack is placed in the simulation tooling, and the corresponding test results can be obtained for various working environments. The obtained data is more valuable for reference.

[0003] Most of the existing thermal runaway test tools for vehicle battery packs are box-like structures with an opening on one side. During the test, the battery pack is placed into the box-like structure from the opening and then the opening is covered with a lid.

[0004] The defects of this tooling include: the size of the inner cavity of the box-like structure is fixed, and the height cannot be adjusted according to the thickness of the battery pack, resulting in different distances between the battery pack and the inner surface of the box-like structure after battery packs of different specifications are placed in the box-like structure. The effect of simulating the working environment of the battery pack in the vehicle is poor, making it difficult to meet the distance value requirements of the thermal runaway test, thereby reducing the test accuracy.

[0035] Embodiment 1

[0036] This embodiment discloses a vehicle battery installation simulation tooling, which is used to cooperate with various whole-package thermal runaway (such as puncture, overcharging, heating) tests, and is particularly suitable for vehicle battery thermal runaway simulation tests.

[0037] like Figure 1 and Figure 2 As shown, the vehicle battery installation simulation tool comprises a tool body 1, a connector 8, a connection assembly and a gap height adjustment device, wherein the tool body 1 is arranged on the battery pack to be tested 7 (such as Figure 6 The tool body 1 is above the battery pack 7 to be tested and there is a gap between the tool body 1 and the battery pack 7 to be tested, simulating the chassis of the vehicle. The connector 8 is connected to the battery pack 7 to be tested, and the gap height adjustment device is arranged between the tool body 1 and the connector 8. In this embodiment, the tool body 1 is plate-shaped, which can better simulate the vehicle floor.

[0038] There are two methods for adjusting the gap height by the gap height adjustment device. One method is: the gap height adjustment device includes a series of structures of different lengths, which are located between the lower surface of the tooling body 1 and the battery pack 7 to be tested (such as Figure 6 By placing a gap height adjustment device of suitable length between the upper surface of the tooling body 1 and the battery pack to be tested 7 (as shown in FIG. Figure 6The gap height value between the two parts (as shown) meets the test requirements; the other is: the gap height adjustment device is a structure with adjustable length itself, for example, the gap height adjustment device includes a sleeve with an internal thread and a column with an external thread, the internal thread of the sleeve is matched with the external thread of the column, and the column is rotated relative to the sleeve to change the length of the column protruding from the sleeve, thereby changing the length of the gap height adjustment device itself.

[0039] It is understandable that the gap height adjustment device is located between the tooling body 1 and the connector 8 to adjust the gap height between the two. In order to improve the stability of the overall structure, one end of the gap height adjustment device is connected to the tooling body 1, and the other end of the gap height adjustment device is connected to the connector 8. The specific connection method is not limited, as long as it can ensure that the gap height adjustment device is not separated from the tooling body 1 and the connector 8. In addition, the extension direction of the "length" used above is consistent with the extension direction of the "gap between the tooling body 1 and the battery pack 7 to be tested".

[0040] The simulation tool can use the tool body 1 to simulate the vehicle chassis, and use the screw rod 2 and the bolt 3 to realize the connection between the tool body 1 and the battery pack 7 to be tested (such as Figure 6 The gap height adjustment device can be used to adjust the gap between the tooling body 1 and the battery pack to be tested 7 (as shown in FIG. Figure 6 The gap height value (as shown) can meet specific test requirements and simulate the working environment of the battery pack in the vehicle as accurately as possible, with high test accuracy. The simulation tooling has a simple overall structure, is easy to use, has low cost, and has high processing efficiency.

[0041] The specific structure of the connecting component is not limited, and can connect the tooling body 1 and the battery pack to be tested 7 (such as Figure 6 In this embodiment, the connection assembly includes a screw rod 2 and a bolt 3 connected by threads. The screw rod 2 passes through the tooling body 1, the gap height adjustment device and the connecting piece 8 from top to bottom. The bolt 3 is sleeved on the screw rod 2 from below, so as to realize the tooling body 1 and the battery pack to be tested 7 (as shown in FIG. Figure 6 shown) connections.

[0042] In order to increase the strength of the tooling body 1 and avoid deformation or even damage of the tooling body 1 when the battery is thermally runaway, a reinforcement is connected to the side of the tooling body 1 facing away from the battery pack 7 to be tested. In this embodiment, the reinforcement includes at least one square steel, preferably at least two square steels arranged in a cross direction, which can strengthen the tooling body 1 from different directions. "Cross-direction arrangement" means that at least two square steels are in a non-parallel state to avoid all square steels being arranged in parallel, resulting in low strength of the tooling body 1 between two adjacent square steels. The two square steels arranged in a cross direction can be in a cross state, that is, one square steel passes through another square steel; the two square steels arranged in a cross direction can also be in a non-cross state, that is, there is a gap between the end of one square steel and the other square steel. The specific angle between the two square steels in a non-parallel state is not limited. In this embodiment, the two square steels are arranged vertically, which is convenient for processing and can significantly increase the strength of the tooling body 1. Each square steel is welded to a side surface of the tooling body 1 facing away from the battery pack 7 to be tested, so the processing efficiency is high and the connection structure between the square steel and the tooling body 1 is stable.

[0043] When four or more square steels are included, at least two square steels are arranged along the first direction, at least two square steels are arranged along the second direction, and all square steels form a grid structure. The first direction and the second direction are preferably perpendicular to each other, and the square steels arranged in the first direction and the square steels arranged in the second direction work together to jointly bear and distribute the load on the tooling body 1, so that the tooling body 1 has good strength performance at all angles, is strong and durable, and the strong impact during battery thermal runaway will not damage the tooling body 1, and the tooling body 1 can be reused.

[0044] The specific structure of the reinforcement member is not limited, as long as it can improve the strength of the tooling body 1. Figure 1 , Figure 3 and Figure 4 As shown, the reinforcement member includes at least two first square steels 4 and at least two second square steels 5, the first square steels 4 are arranged along the first direction, the second square steels 5 are arranged along the second direction, the first direction is not parallel to the second direction, all the first square steels 4 and all the second square steels 5 form a grid structure, which has greater strength. In this embodiment, the first direction is perpendicular to the second direction, that is, one of the first square steels 4 and the second square steels 5 is arranged horizontally, and the other of the first square steels 4 and the second square steels 5 is arranged longitudinally.

[0045] In order to further improve the stability, at least two square steels are arranged crosswise. That is, the extension directions of at least two square steels are not parallel and have overlapping points. At the overlapping point, a notch 52 is opened on one square steel, and the other square steel can pass through the notch 52 of the other square steel; or one square steel can pass through the notch 52 of the other square steel, and the two square steels are connected together at the overlapping point by welding, riveting, bonding, etc. Among them, the difference between the "cross setting" and the aforementioned "intersecting setting" is that the two square steels in the "cross setting" have overlapping points (that is, one square steel passes through the other square steel), and the two square steels in the "intersecting setting" have no overlapping points (that is, there is a gap between the end of one square steel and the side of the other square steel.) In this embodiment, a notch 52 is opened on the main body 51 of the second square steel 5, and the first square steel 4 is passed through the notch 52, so that the first square steel 4 and the second square steel 5 are connected into an integrated structure, which can better increase the strength of the tooling main body 1.

[0046] In order to prevent the notch 52 from cutting off the second square steel 5 and causing the second square steel 5 to have its own strength reduced, in this embodiment, the height of the second square steel 5 protruding from the tooling body 1 is greater than the height of the first square steel 4 protruding from the tooling body 1. Preferably, the cross section of the first square steel 4 is square, which is stronger; the cross section of the second square steel 5 is rectangular, ensuring that the first square steel 4 is allowed to pass through without being cut off, and at the same time, there is no need to increase the width of the second square steel 5 (i.e., the direction in which the first square steel 4 is passed through), so as to minimize the material of the second square steel 5 and save costs. The height of the notch 52 can be equal to the height of the first square steel 4, so as to ensure that the first square steel 4 can be passed through the notch 52 while reducing the strength of the second square steel 5 as little as possible.

[0047] The specific shape of the notch 52 is not limited. In this embodiment, the open end of the notch 52 is attached to the surface of the tooling body 1. After the first square steel 4 is inserted into the notch 52, the bottom surfaces of the first square steel 4 and the second square steel 5 can be welded to the tooling body 1, so that all the first square steels 4, all the second square steels 5 and the tooling body 1 form an integral structure with higher strength, durability, and the ability to cope with the huge impact of battery thermal runaway.

[0048] The specific number and size of the square steels are not limited. In this embodiment, the vehicle battery installation simulation tooling includes five first square steels 4, each of which has the same width as height and high strength, and serves as the main structure to bear the force on the tooling body 1. The vehicle battery installation simulation tooling also includes five second square steels 5, each of which is higher than each first square steel 4, and the width of each second square steel 5 is smaller than the width of each first square steel 4. On the one hand, the strength of the tooling body 1 in the second direction is increased, and on the other hand, all the first square steels 4 that are parallel to each other are connected to form an integral structure.

[0049] On the basis of the above structure, the screw rod 2 passes through the reinforcement member and the tooling body 1 respectively, so that the force acting on the screw rod 2 can be shared by the reinforcement member and the tooling body 1 at the same time, so as to enhance the ability of the vehicle battery installation simulation tooling to withstand impact. Figure 4 As shown, a connecting through hole 53 is provided on the second square steel 5. Figure 1 and Figure 4 As shown, the screw rod 2 first passes through the connecting through hole 53 and then passes through the through hole (not shown) on the tool body 1.

[0050] The specific structure of the gap height adjustment device is not limited, and can adjust the gap height between the tooling body 1 and the battery pack to be tested 7 (such as Figure 6 In this embodiment, the gap height value between Figure 1 and Figure 2 As shown, the gap height adjustment device includes a cylindrical support member 6, which is sandwiched between the tool body 1 and the connecting member 8. During installation, the screw rod 2 is inserted into the support member 6, and the bolt 3 can prevent the support member 6 from being separated from the screw rod 2.

[0051] The support member 6 may include a series of cylindrical structures with different heights. Figure 6 When the gap height value between the test pieces 1 and 2 (as shown in the figure) changes, the support piece 6 of the corresponding height can be replaced. The "corresponding height" means that the gap height value is equal to the gap height value, or there is a set tolerance between the gap height value, which can make the tooling body 1 and the battery pack 7 to be tested (as shown in the figure) to be tested after the support piece 6 is set. Figure 6 By replacing the support members 6 of different heights, the height between the tooling body 1 and the battery pack to be tested 7 (as shown in FIG. Figure 6 The gap height value between the two is shown in the figure, which is more convenient to use and has a wide range of applications.

[0052] On the basis of the above structure, the gap height adjustment device further includes a gasket (not shown), which is arranged above and / or below the support member 6, that is, the gasket is clamped between the support member 6 and the tool body 1, and / or the gasket is clamped between the support member 6 and the connecting member 8. When there is no support member 6 to accurately adjust the gap height between the tool body 1 and the battery pack 7 to be tested (such as Figure 6 When the gap height value between the tool body 1 and the battery pack to be tested 7 (as shown) is set, it can be fine-tuned by adding or reducing spacers, which is more convenient to use and ensures that the tool body 1 and the battery pack to be tested 7 (as shown) are Figure 6 For example, the length of the support member 6 is 5 cm, and the height of the gap between the tool body 1 and the battery pack to be tested 7 (as shown) meets the use requirements. Figure 6 The clearance height between the tool body 1 and the battery pack 7 to be tested (as shown) is required to be 6 cm. At this time, a 6 cm long support member 6 can be replaced, or a 1 cm thick gasket can be added on the basis of the 5 cm support member 6. Figure 6 The gap height between the two ends is as high as 6 cm.

[0053] In order to improve the stability of the connection of the bolt 3, the vehicle battery installation simulation tool also includes an elastic washer 9. When the bolt 3 is threadedly connected to the bottom end of the screw rod 2, the elastic washer 9 is arranged between the bolt 3 and the connecting member 8 (such as Figure 2 and Figure 7 The elastic washer 9 can press the bolt 3 in a direction away from the connecting member 8, thereby increasing the friction between the internal thread of the bolt 3 and the external thread of the screw rod 2, and making the threaded connection between the bolt 3 and the screw rod 2 more stable.

[0054] like Figure 5 As shown, the connecting member 8 is provided with a mounting point hole 81. Figure 1 , Figure 2 and Figure 5 As shown, the screw rod 2 is inserted into the mounting point hole 81, and the bolt 3 can prevent the screw rod 2 from coming out of the mounting point hole 81, which is safer to use and has high disassembly and assembly efficiency. The specific number of screw rods 2 is not limited, as long as they can be stably connected. In this embodiment, three screw rods 2 are connected to each connecting member 8, and the load-bearing capacity is strong. Of course, it is also feasible to connect one screw rod 2, two screw rods 2, four or more screw rods 2 to each connecting member 8. The number of gap height adjustment devices can be consistent with the number of screw rods 2, and the setting positions of the screw rods 2 and the gap height adjustment devices can be determined according to the shape of the connecting member 8. In this embodiment, all the screw rods 2 connected to each connecting member 8 are arranged at equal intervals, and the force is more balanced.

[0055] The specific number of connectors 8 included in each vehicle battery installation simulation tool is not limited, and the tool body 1 can be connected to the battery pack 7 to be tested (such as Figure 6 In this embodiment, the battery pack to be tested 7 (as shown) can be stably connected. Figure 6 Connectors 8 are respectively arranged on the two opposite sides of the battery pack 7 to be tested (as shown in FIG. 1 ), that is, the vehicle battery installation simulation tooling includes two connectors 8. Figure 6 ) are respectively provided with connectors 8 around them, that is, the vehicle battery installation simulation tooling includes a total of four connectors 8, and the battery pack 7 to be tested (such as Figure 6 The connection shown in the figure is more stable; it is also feasible for the vehicle battery installation simulation tool to include one, three, five or more connecting members 8.

[0056] Embodiment 2

[0057] This embodiment discloses a vehicle battery installation simulation system, such as Figure 6 and Figure 7As shown, the vehicle battery installation simulation system includes at least one group of battery packs to be tested 7 and a vehicle battery installation simulation tool, and the connector 8 of the vehicle battery installation simulation tool is connected to at least one group of battery packs to be tested 7, wherein the vehicle battery installation simulation tool has the same structure as that in Example 1 and will not be repeated here.

[0058] The tool body 1 is located above the battery pack 7 to be tested, and a gap is left between the lower surface of the tool body 1 and the upper surface of the battery pack 7 to be tested. The height of the gap can be adjusted by selecting support members 6 of different lengths. The specific height of the gap between the lower surface of the tool body 1 and the upper surface of the battery pack 7 to be tested is not limited and can be determined according to specific usage conditions.

[0059] During assembly, the first square steel 4 and the second square steel 5 are welded to the tool body 1 respectively, the connector 8 is connected to the battery pack 7 to be tested, the vehicle battery installation simulation tool is placed on the battery pack 7 to be tested, the support member 6 is arranged between the tool body 1 and the connector 8, and the screw 2 is aligned with the mounting point hole 81 on the connector 8 (such as Figure 5 The screw 2 passes through the second square steel 5, the tooling body 1, the support member 6 and the mounting point hole 81 from top to bottom (as shown); Figure 5 As shown), the bolt 3 is sleeved on the outer periphery of the screw rod 2 from below and is threadedly connected with the screw rod 2 to complete the assembly.

[0060] The specific connection position and connection method of the connector 8 and the battery pack to be tested 7 are not limited, as long as they can be stably connected. In this embodiment, the connector 8 is connected to the side of the battery pack to be tested 7, which is easy to install and prevents the connector 8 from affecting the gap height value between the tool body 1 and the battery pack to be tested 7; the connector 8 can be connected to the battery pack to be tested 7 by various methods such as bonding, bolting, and clamping, which will not affect the use of the vehicle battery installation simulation system.
