Technical Field

[0001] This utility model relates to the field of battery pack testing technology, and in particular to a vibration bracket for an automotive power battery pack. Background Technology

[0002] Vibration testing refers to the testing performed on a physical object or model subjected to vibration to evaluate the product's resistance to vibration in its intended use environment. Based on the type of applied vibration load, vibration testing is divided into two types: sinusoidal vibration testing and random vibration testing.

[0003] Before being installed in a vehicle, the power battery packs used in electric vehicles, pure electric vehicles, or hybrid vehicles must undergo vibration testing. During vibration testing, a vibration bracket is required to secure the battery pack. However, the current method of securing the battery pack involves placing it in a box for testing, which is inconvenient for securing battery packs of different sizes. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems and shortcomings by proposing a vibration bracket for automotive power battery packs: a sliding plate on the outer wall of a threaded rod and a bidirectional screw is close to the battery pack, and the sliding plate clamps the battery pack through a contact pad, which facilitates the fixing of battery packs of different sizes and confines the battery pack between the sliding plates, making it easy to fix battery packs of different sizes, convenient to use, and improving experimental stability, thus solving the problem of inconvenience in fixing multiple sizes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vibration bracket for an automotive power battery pack includes a base plate. Sliding rods are welded to the four corners of the top outer wall of the base plate, and the outer walls of the sliding rods are slidably connected to a fixing structure. The fixing structure includes a gravity plate, connecting rods welded to the center of the top outer walls on both sides of the gravity plate, fixing grooves opened at the center of the bottom outer wall of the gravity plate and the center of the bottom outer wall of the connecting rod, a bidirectional screw rod rotatably connected to the fixing groove of the gravity plate, and a threaded rod rotatably connected to the center of the fixing groove in the connecting rod.

[0007] Both ends of the threaded rod and the bidirectional screw are threaded with sliding plates, and one end of the sliding plate is slidably connected to the inner wall of the fixed groove.

[0008] Preferably, driving protrusions are welded to the outer walls of both ends of the bidirectional screw and the outer wall of one end of the threaded rod, and one end of the outer wall of the driving protrusion is slidably connected to the outer wall of the gravity plate and the connecting rod.

[0009] According to the above scheme: the sliding plate on the outer wall of the threaded rod and the bidirectional screw is close to the battery plate. The sliding plate clamps the battery pack through the contact pad, which makes it easy to fix battery packs of different sizes and restrict the battery pack between the sliding plates. This makes it easy to fix battery packs of different sizes, easy to use, and easy to improve experimental stability.

[0010] Preferably, the bottom outer wall of the gravity plate and the outer wall of the sliding rod that are close to each other are both bonded with contact pads, and the contact pads of the gravity plate are provided with strip-shaped holes at the fixing groove.

[0011] Preferably, the top outer wall of the sliding rod is provided with a threaded groove, and the sliding rod is threadedly connected to a screw block in the threaded groove. A compression spring is welded to the bottom outer wall of the screw block.

[0012] Preferably, a contact ring is welded to the bottom outer wall of the compression spring, and the contact ring is sleeved on the outer wall of the sliding rod, with the bottom outer wall of the contact ring in contact with the top outer wall of the gravity plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] The sliding plate on the outer wall of the threaded rod and the bidirectional screw is close to the battery plate. The sliding plate clamps the battery pack through the contact pad, which makes it easy to fix battery packs of different sizes and restrict the battery pack between the sliding plates. This makes it easy to fix battery packs of different sizes, easy to use, and helps to improve experimental stability. Attached Figure Description

[0024] Both ends of the bidirectional screw 10 and one end of the threaded rod 11 are welded with driving protrusions 14. One end of the outer wall of the driving protrusion 14 is slidably connected to the outer wall of the gravity plate 7 and the connecting rod 8. After the bidirectional screw 10 and the threaded rod 11 on the gravity plate 7 rotate, they drive the sliding plate 12 to approach the battery pack and restrict the four sides of the battery pack inside, which is convenient for fixing battery packs of different sizes.

[0025] Contact pads 13 are bonded to the bottom outer wall of gravity plate 7 and the outer wall of sliding rod 2 on the side closest to each other. The contact pads 13 of gravity plate 7 are provided with strip-shaped holes at the fixing groove 9. The contact pads 13 of gravity plate 7 and sliding plate 12 are in contact with the outer wall of battery pack, which facilitates the protection of battery pack when clamped.

The bottom outer wall of the threaded block 5 is welded with a downward pressure spring 6. The gravity plate 7 is supported by the threaded block 5 and the downward pressure spring 6 to press the battery pack on the top of the base plate 1, which facilitates the fixation of the battery pack. The threaded block 5 is fixed to the top of the sliding rod 2. The downward pressure spring 6 and the contact ring apply force to the gravity plate 7 to ensure that the gravity plate 7 is fixed and stable.

[0027] A contact ring is welded to the bottom outer wall of the compression spring 6. The contact ring is sleeved on the outer wall of the sliding rod 2, and the bottom outer wall of the contact ring contacts the top outer wall of the gravity plate 7.

[0028] Working principle: During use, the base plate 1 is fixed at the test position on the vibration test bench. The battery pack to be tested is placed on the top outer wall of the base plate 1. The four ends of the gravity plate 7 are aligned with the sliding rod 2 and slidably connected to the sliding rod 2. Under its own weight, the gravity plate 7 presses down on the top of the battery pack. The contact pad 13 protects the battery pack. The drive protrusion 14 drives the bidirectional screw 10 and the threaded rod 11 to rotate. The sliding plate 12 on the outer wall of the threaded rod 11 and the bidirectional screw 10 approaches the battery pack. 12 The battery pack is clamped by the contact pad 13 to facilitate the fixation of battery packs of different sizes and to restrict the battery pack between the sliding plates 12. Finally, the contact ring and the pressure spring 6 are fitted into the outer wall of the sliding rod 2. The screw block 5 is threaded into the threaded groove 4 at the top of the sliding rod 2 and fixed at the top of the sliding rod 2. The pressure spring 6 and the contact ring apply force to the gravity plate 7 to ensure the stability of the gravity plate 7. After starting the vibration test bench, the battery pack is subjected to a vibration test to prevent the battery pack from falling due to vibration.
