Description

Technical Field

[0001] The utility model relates to a vibration testing tool, in particular to a battery transverse vibration testing tool. Background Art

[0002] Currently, with the development of domestic technology, the replacement of domestically produced civil avionics products is ongoing. A single aircraft may contain hundreds or even thousands of different onboard avionics products. As we all know, electronic products require power to operate. For certain battery-powered avionics products, their batteries are considered part of the aircraft's assembly, requiring appropriate reliability testing to verify their stability, taking into account factors such as safety, service life, and replaceability.

[0003] In the field of aviation lithium battery testing, vibration testing, conducted on physical or mock-up test pieces to assess the vibration resistance of a product in its intended operating environment, is becoming increasingly common, as it meets the vibration and impact testing requirements of the "DO-227A Minimum Performance Standard for Non-Rechargeable Lithium Batteries." However, in actual use, the test piece often cannot be securely fastened directly to the vibration table. Therefore, a suitable test fixture must be designed to ensure a secure connection between the test piece and the vibration table. The existing battery vibration test fixture has the following disadvantages: (1) The existing battery vibration test fixture can only ensure the fixation between the test specimen and the vibration table, but cannot monitor its actual status. It can only be taken out from the fixture after the test is completed to conduct corresponding performance testing. The installation and disassembly of the vibration test specimen is cumbersome, and such repeated testing is very likely to cause waste of resources; (2) The lateral vibration test fixture is suitable for vibration testing of the X-axis and Y-axis when the battery is placed upright, while general vibration test fixtures are made of metal. When the battery is in an upright state, the positive and negative terminals can easily form a discharge circuit with the test fixture, which will inevitably cause damage to the battery and affect the test results; (3) Due to the different requirements for the number of test specimens in various battery performance standards, the common battery vibration test fixture can only support the simultaneous testing of 20 to 30 battery specimens, which cannot meet the requirements for the number of vibration test samples in DO-227A. Summary of the Invention

[0004] In order to solve the problems of cumbersome installation and disassembly of existing battery lateral vibration test fixtures, the positive and negative terminals of the battery in the upright state easily forming a discharge circuit with the test fixture, which inevitably causes battery damage, and an insufficient number of battery samples to be tested, a battery lateral vibration test fixture was designed.

[0005] A battery lateral vibration test tool, comprising at least a vibration table, a first limit plate and several pressure plates for pressing the other end of the battery, wherein the first limit plate is installed on the vibration table, one end of the pressure plate is installed on a first vertical plate vertically arranged on the first limit plate through a hinge, and the other end of the pressure plate is installed on a second vertical plate vertically arranged on the first limit plate through a lock; the first limit plate has several circular grooves for installing one end of the battery; the contact surface between the first limit plate and the battery has a first wire groove for leading out wiring from the circular groove, and the contact surface between the pressure plate and the battery has a second wire groove for wiring; it also includes a second limit plate installed on the first limit plate, the second limit plate has a circular hole for installing the battery, so that the middle section of the battery passes through the circular hole, and the hole wall of the circular hole limits the radial displacement of the battery.

[0006] The second limit plate is an insulating wooden block used to stabilize the battery sample and prevent it from falling out of the tooling. The pressure plate is made of insulating material.

[0007] Furthermore, an insulating block is placed between the pressing plate and the battery. The pressing plate has a groove for mounting the insulating block. The insulating block is made of silicone, ensuring that no discharge loop forms between the battery and the tooling, thereby preventing battery sample loss. The silicone material of the insulating block also acts as a buffer and shock absorber.

[0008] Furthermore, the device further comprises a bottom plate installed between the vibration table and the first limit plate. The bottom plate is made of aluminum alloy and serves to strengthen the structure of the first limit plate.

[0009] The beneficial effects of this application are:

[0010] (1) The hinge and lock of the pressure plate make it easy to disassemble and assemble the battery.

[0011] (2) Each battery has a dedicated first wire slot and second wire slot to facilitate the lead-out of the wires and monitor the status of all batteries during the test.

[0012] (3) The cooperation between the circular groove and the pressure plate supports vibration testing of a large number of batteries at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The fixture also includes a second limiting plate 4 mounted on the first limiting plate 1, the second limiting plate 4 having a circular hole 4-1 for mounting the battery, so that the middle section of the battery passes through the circular hole 4-1, and the hole wall of the circular hole 4-1 limits the radial displacement of the battery.

[0024] In this embodiment, a total of 6 pressing plates are provided, each of which can press 8 batteries, meeting the requirement of vibrating 48 single-cell batteries in the vertical position in the X and Y axes at the same time, with a capacity higher than that of battery vibration tooling currently on the market.

[0028] By providing an insulating block 8, which is an insulating wooden block, it is ensured that no discharge circuit is formed between the battery and the tooling, thereby avoiding the loss of the battery sample. The silicone material of the insulating block also plays a role in buffering and shock absorption.

[0029] Example 3

[0030] like Figure 6 The difference between this embodiment and embodiment 1 is that a base plate 2 installed between the vibration table 1 and the first limiting plate 3 is added.

Compared with the existing technology, it can allow more battery samples to undergo vibration testing at the same time, basically covering the quantity requirements of all current battery vibration test standards.

[0034] In some embodiments, more or fewer circular grooves and pressing plates 5 may be provided as required, thereby increasing or decreasing the number of battery tests.

[0035] The utility model hollows out the positive and negative poles of the battery, leaving space as the first wire slot 3-1 and the second wire slot 5-1 to directly pass to the outside, so as to facilitate the corresponding status monitoring of each battery during the test. At the same time, the pressure plate 5 at the positive pole is an insulating wooden block to ensure that no discharge circuit can be formed between the battery and the tooling, thereby avoiding the loss of the battery sample.
