Description

Technical Field

[0001] The utility model relates to a tooling for vibration testing of a power battery pack, belonging to the field of tooling for vibration testing of battery packs. Background Technique

[0002] With the development of new energy electric vehicle technology and the further increase of national subsidies for high-endurance vehicles, the battery pack integration system is also developing towards high integration, high capacity and high energy. When the battery cells are fixed, increasing the number of battery modules is one of the effective methods to improve the energy of the battery pack. Therefore, existing battery packs are often relatively heavy and high-energy, which will pose a new challenge to the structural strength and design rationality of the power battery pack. Therefore, during the research and development stage of a new power battery pack system, it is very important and necessary to verify the structural safety. Through vibration tests, problems existing in the previous structural design can be well discovered.

[0003] In the prior art, since a tooling for vibration testing of a power battery pack is used during the vibration testing of the power battery pack, the battery vibration testing tooling consists of a base, a table, a limiting member, a support plate and mounting holes. Therefore, during use, the bottom of the battery pack needs to be in contact with the mounting holes through bolts, so that the battery pack is fixed on the surface of the table, and then the battery pack is limited by the limiting member to prevent the position of the battery pack from changing during the vibration test. However, during the vibration testing of the power battery pack, since the limiting member is in contact with the surface of the battery pack, and the battery pack is in a vibration testing state, it is easy to cause friction between the limiting member and the surface of the battery pack under the action of vibration, resulting in scratches on the surface of the battery pack due to the contact with the limiting member during vibration. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a tooling for vibration testing of a power battery pack to solve the problems raised in the above background technique. The utility model solves the problem of scratches caused by friction on the battery surface when the battery pack contacts the limiting member.

[0005] In order to achieve the above purpose, the utility model is realized through the following technical solutions: A tooling for vibration testing of a power battery pack includes a base, a hole groove is formed on the surface of the base, a support plate is fixedly arranged at the side end of the top surface of the base, a top plate is fixedly connected to the top of the support plate, and a table is fixedly arranged at the center of the top of the base;

[0006] A long board is fixedly arranged at the top of the base. A chute is arranged inside the long board. An electric telescopic rod is fixedly connected to the inner side end of the chute. An electric push rod is fixedly connected to the end of the electric telescopic rod. A clamping block is fixedly connected to the top surface of the electric push rod. A groove plate is fixedly connected to the bottom of the clamping block. A support rod is fixedly connected to the top of the electric push rod.

[0007] Further, the long board is arranged at the position where the top of the base contacts the bottom of the support plate. There are two symmetrically arranged long boards. Two electric telescopic rods corresponding in position are arranged inside the chute of the long board. The end of each electric telescopic rod corresponds to an electric push rod. The tops of two symmetrically arranged support rods contact the same connecting plate. The shape and position of the groove plate match those of the long board.

[0008] Further, the bottom of the sliding block contacts the top of the top plate. There are two symmetrically arranged fixing blocks on the surface of the connecting plate. An arc plate and a resisting plate are respectively connected to two sides of each fixing block. A groove matching the shape of the connecting plate is arranged at the position where the fixing block contacts the connecting plate. The resisting plate is a component made of a silicone material.

[0009] Further, a round block is fixedly connected to the side of the fixing block. A bolt is threadedly connected to the center of the round block. A second clamping groove is arranged on the surface of the arc plate. A receiving block is movably connected to the second clamping groove. A connecting block is fixedly connected to the surface of the receiving block. A receiving rod is fixedly connected to the surface of the connecting block. A pulling plate is fixedly connected to the surface of the receiving rod. A limiting groove is arranged at the top of the surface of the arc plate. A clamping rod is fixedly arranged inside the limiting groove.

[0010] Further, the bottom of the round block contacts the connecting plate. One round block is symmetrically arranged at each of the two ends of the position where the fixing block contacts the connecting plate. The bolt passes through the connecting plate to connect two round blocks corresponding in position.

[0011] Further, the bottom of the clamping rod fixedly contacts the receiving block. There are two receiving blocks arranged inside the second clamping groove. The connecting blocks and receiving rods on the surfaces of the two receiving blocks are connected by the same pulling plate.

[0012] Advantages of the present utility model: First, the battery pack needs to be fixed on the surface of the seat by bolts in contact with the hole grooves, and then the electric telescopic rod is started. The electric telescopic rod pushes the position of the electric push rod. At this time, the support rod and the connecting plate move along with the push of the electric telescopic rod. At the same time, the slider moves on the top of the top plate, and the abutting block on the back of the fixed block contacts the surface of the battery pack. The contact between the abutting block and the surface of the battery pack can prevent scratches caused by the friction between the limiting member and the battery pack due to vibration during the vibration test of the power battery pack.

[0013] Secondly, the bolt needs to be removed and the pull plate is pulled. Under the action of the pull plate, the receiving rod, the connecting block and the receiving block move. The clamping rod restricts the position of the receiving block inside the second card slot. The fixed block is driven by the pull plate to change its position. The position of the main-view abutting block is adjusted to contact the battery pack, and then the electric push rod is started. The electric push rod pushes the position of the support rod, causing the connecting plate to change. In this way, the position of the fixed block can be adjusted according to different shapes of battery packs. BRIEF DESCRIPTION OF THE DRAWINGS

Then, the fixed block 502 is driven by the pull plate 706 to change its position. At the same time, it is necessary to adjust the position of the abutting block 506 to the position in contact with the battery pack. At this time, the electric push rod 403 is started, so that the electric push rod 403 pushes the position of the support rod 5, causing the connecting plate 501 to change. In this way, the position of the fixed block 502 can be adjusted according to different-shaped battery packs.
