[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0032] In view of the deficiencies or one of the deficiencies in the above background technology, the embodiments of the present application provide a vibration and thermal runaway integrated tooling, which can be used for both vibration testing and thermal runaway testing of battery modules.

[0033] See Figures 1 to 6As shown in the figure, the embodiment of the present application provides an integrated tool for vibration and thermal runaway, including:

[0034] A plate assembly 1, which includes two flat plates 11 for supporting or clamping a battery module;

[0035] A hinge member 2, which includes two hinge leaves 21 hinged to each other. Two ends of the hinge member 2 are respectively rotatably connected to the two flat plates 11;

[0036] A locking member 3, which is used to drive the two flat plates 11 to approach each other to clamp the battery module.

[0037] In the integrated tool for vibration and thermal runaway according to the embodiment of the present application, the two flat plates 11 of the plate assembly 1 are connected by the hinge member 2. Since the hinge member 2 includes two hinge leaves 21 hinged to each other, and two ends of the hinge member 2 are respectively rotatably connected to the two flat plates 11, the two flat plates 11 can rely on the hinge member 2 to achieve mutual contact and overlap or mutual parallel spacing.

[0038] When the two flat plates 11 are in mutual contact and overlap, they can act as the bottom plate for fixing the battery module, which is convenient for the overall installation on the vibration test equipment, so that the vibration equipment can perform vibration tests on the battery module; when the two flat plates 11 are in mutual parallel spacing, they can act as the clamping plates for clamping the battery module, and then cooperate with the locking member 3 to drive the two flat plates 11 to approach each other to clamp the battery module, so as to facilitate the thermal runaway test.

[0039] Exemplarily, when the two flat plates 11 are unfolded in the same plane, by using the two hinge leaves 21 hinged to each other, one of the flat plates 11 can be flipped and overlapped on the surface of the other flat plate 11. Holes are pre-opened on the two flat plates 11 to facilitate the fasteners to penetrate through the two flat plates 11 at the same time to fix them on the vibration test equipment to act as the bottom plate for fixing the battery module. Further, holes or grooves with different specifications and sizes can be provided on the two flat plates 11 to respectively be applicable to fixing battery modules with different specifications and sizes.

[0040] Since the ends of the two hinge leaves 21 of the hinge member 2 away from their hinge center are rotatably connected to the flat plate 11, therefore, the two flat plates 11 in mutual contact and overlap can be relatively pulled apart to keep the two flat plates 11 parallel and spaced apart. The battery module can be placed between the two flat plates 11 to realize that the two flat plates 11 act as the clamping plates for clamping the battery module, and then cooperate with the locking member 3 to drive the two flat plates 11 to approach each other to clamp the battery module, so as to facilitate the thermal runaway test. Exemplarily, the locking member 3 can adopt an electric or hydraulic working cylinder, or other driving members that can achieve pushing.

[0041] In some alternative embodiments: Refer to Figures 1 to 6As shown in the figure, the embodiment of the present application provides a vibration and thermal runaway integrated tooling. The number of hinge members 2 of the vibration and thermal runaway integrated tooling is two sets, and the two sets of hinge members 2 are respectively arranged at both ends of the plate assembly 1.

[0042] The number of hinge members 2 of the vibration and thermal runaway integrated tooling in the embodiment of the present application is two sets, which are respectively installed at both ends of the plate assembly 1, which can improve the connection reliability and facilitate the stable flipping of the flat plate 11. Exemplarily, in this embodiment, the two flat plates 11 are made of aluminum alloy plates with the same size. The large surface where the length and width are located on the flat plate 11 is used to support or clamp the battery module, and the small surface where the width and thickness are located is used to connect the hinge member 2. The two sets of hinge members 2 are respectively rotatably connected to the small surfaces of the two flat plates 11. At the same time, there is a certain distance between the two flat plates 11 in the unfolded state, which is convenient for flipping and overlapping each other.

[0043] In some alternative embodiments: Refer to Figures 1 to 6 As shown in the figure, the embodiment of the present application provides a vibration and thermal runaway integrated tooling. The hinge leaves 21 of each set of hinge members 2 of the vibration and thermal runaway integrated tooling are all rotatably connected to the same rotating shaft 4.

[0044] The hinge leaves 21 of each set of hinge members 2 of the vibration and thermal runaway integrated tooling in the embodiment of the present application are all rotatably connected to the same rotating shaft 4. The rotating shaft 4 connects the two sets of hinge members 2 into one body, which can improve the connection reliability and flipping stability.

[0045] Specifically, in the unfolded state, the rotating shaft 4 is located between the two flat plates 11. When the flat plates 11 are flipped and overlapped, under the constraint of the rotating shaft 4, the hinge leaves 21 on both sides move synchronously, which can ensure the flipping stability. In some other embodiments, when the two flat plates 11 are in the flipped and overlapped state, the rotating shaft 4 can act as a handle to facilitate the movement of the two flat plates 11.

[0046] In some alternative embodiments: Refer to Figures 1 to 6 As shown in the figure, the embodiment of the present application provides a vibration and thermal runaway integrated tooling. The hinge leaf 21 of the vibration and thermal runaway integrated tooling includes two connecting arms 211 that are relatively slidably connected to realize the telescopic movement of the hinge leaf 21.

[0047] The hinge leaf 21 of the vibration and thermal runaway integrated tooling in the embodiment of the present application is a telescopic structure formed by the mutual sliding connection of two connecting arms 211. When the two flat plates 11 are arranged parallel to each other at intervals to act as clamping plates for clamping the battery module, in cooperation with the telescopic hinge leaf 21, the distance between the two flat plates 11 can be adjusted within a larger range, which is convenient for clamping battery modules with larger specifications and sizes.

[0048] In some alternative embodiments: Refer to Figures 1 to 6As shown, an embodiment of the present application provides a vibration and thermal runaway integrated tooling, wherein each connecting arm 211 of the hinge 21 of the vibration and thermal runaway integrated tooling is provided with a sliding frame 212 for another connecting arm 211 to pass through.

[0049] Each connecting arm 211 of the hinge 21 of the vibration and thermal runaway integrated tooling in the embodiment of the present application is provided with a sliding frame 212 for the other connecting arm 211 to pass through. Specifically, one end of the connecting arm 211 is integrally provided with a rectangular sliding frame 212, and the two connecting arms 211 pass through the sliding frames 212 thereon to form a retractable hinge 21.

[0050] In some alternative embodiments: See Figures 1 to 6 As shown, an embodiment of the present application provides a vibration and thermal runaway integrated tooling, wherein a sliding hole 213 is provided on one connecting arm 211 of the hinge 21 of the vibration and thermal runaway integrated tooling, and a slider 214 cooperating with the sliding hole 213 is provided on the other connecting arm 211.

[0051] The two connecting arms 211 of the hinge 21 of the vibration and thermal runaway integrated tooling of the embodiment of the present application cooperate with each other through a sliding hole 213 and a slider 214 to realize the retractability of the hinge 21. For example, the sliding hole 213 is in the shape of a strip, and the slider 214 is a T-shaped block. The small end of the T-shaped block is fixedly installed and slidably adapted to the sliding hole 213, and the large end can prevent the T-shaped block from detaching from the sliding hole 213.

[0053] The four corners of the two flat plates 11 of the vibration and thermal runaway integrated tooling of the embodiment of the present application are provided with through holes 111, and the through holes 111 can be passed through the screws 31, and the screws 31 are then fitted with nuts 32. The nuts 32 are used to tighten the flat plates 11, thereby achieving clamping of the battery module.

[0054] Exemplarily, the battery module is placed between two parallel and spaced-apart plates 11, four screws 31 are prepared, and respectively pass through the through holes 111 reserved at the four corners of the plates 11, and both ends of each screw 31 pass through the through holes 111 on the two side plates 11, and nuts 32 are installed at both ends of the screw 31.

[0055] Adjust the distance between the two nuts 32 on the same screw 31. Limit the flat plate 11 through the nuts 32, that is, after adjusting the distance between the two flat plates 11, the nuts 32 on the opposite sides of the two flat plates 11 can press against the flat plate 11, so that the two flat plates 11 can clamp battery modules of different sizes.
