Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts test and detection, more particularly to a novel storage box fatigue test fixture. BACKGROUND

[0002] In 2024, China's automobile production and sales reached 24.466 million and 24.624 million, up 1.9% and 2.7% respectively, maintaining steady growth. With the increase in automobile production and sales, consumers' demand for overall performance and automobile parts functionality is increasing, especially in terms of environmental protection, comfort, intelligence, and human-machine interaction. To meet the increasing demand of consumers for automobiles, automobile manufacturers are paying more attention to fatigue and durability testing of parts, especially storage boxes. To ensure that storage boxes have good storage functionality, stable operating force, and opening time during their entire life cycle, they need to be tested for tens of thousands of times at various temperatures. However, manual testing cannot guarantee the stability and repeatability of the test action, and manual fatigue testing at extreme temperatures can harm the health of test personnel. Therefore, a storage box fatigue test fixture that replaces manual testing is urgently needed in the automobile testing industry. SUMMARY

[0003] The utility model aims at providing a novel storage box fatigue test fixture to solve the problem of instability and repeatability of manual testing during storage box fatigue and durability testing.

[0004] The utility model solves the technical problem by adopting the following technical scheme:

[0005] A novel storage box fatigue test fixture, which comprises a storage box positioning and base plate part 1, a storage box opening-closing mechanism part 2, and a storage box opening-closing position sensor part 3. The storage box opening-closing cylinder 21, storage box pressing unlocking mechanism 22, and cylinder anti-collision mechanism 23 in the storage box opening-closing mechanism part 2 are connected to the second aluminum alloy base plate 13 in the storage box positioning and base plate part 1 through bolts. The storage box closing position sensor 31 and storage box opening position sensor 32 in the storage box opening-closing position sensor part 3 are connected to the third aluminum alloy base plate 14 in the part positioning and base plate part 1 through bolts.

[0006] During testing, select an air source with appropriate pressure according to the test requirements. Extend the storage box opening-closing cylinder 21 in part 2 of the storage box opening-closing mechanism. Fix the storage box to the first part positioning module 12, the second part positioning module 15, and the third part positioning module 16 with bolts according to the torque specified in the assembly drawing, simulating the actual loading angle. Set the number of test cycles on the control panel of the electrical control box and begin the test. The storage box opening-closing cylinder 21 in part 2 of the storage box opening-closing mechanism retracts, and the storage box... The storage box unlocking mechanism 22 acts on the storage box unlock button, then the storage box opening-closing cylinder 21 in part 2 extends to its travel limit position. The storage box unlocking mechanism 22 contacts the cylinder anti-collision mechanism 23 to prevent the cylinder from opening too quickly and causing impact vibration. The storage box also opens. After the storage box is fully opened, the storage box opening position sensor 32 is triggered, and the signal returns to the control box. The system determines that the storage box is fully open to prevent the next cycle from starting before the storage box is fully open. Then, the storage box opening-closing cylinder 21 retracts, and the storage box unlocking mechanism 22 acts on the storage box unlock button to reach the closed position, closing the storage box. This triggers the storage box closing position sensor 31, causing it to be triggered, and the signal returns to the control box to determine that the storage box is fully closed to prevent the next cycle from starting before the storage box is fully closed. This is one cycle. Repeat this cycle according to the test requirements.

During testing, the storage box is installed into the positioning module according to the corresponding positioning holes and tightened by bolts.

[0008] The storage box opening-closing mechanism 2 consists of a storage box opening-closing cylinder 21, a storage box pressing unlocking mechanism 22, and a cylinder anti-collision mechanism 23. The storage box opening-closing cylinder 21 and the cylinder anti-collision mechanism 23 are bolted to the second aviation aluminum substrate 13 in the storage box positioning and base plate part 1. The storage box pressing unlocking mechanism 22 is connected to the second aviation aluminum substrate 13 via a slide rail.

[0009] The storage box opening-closing position sensor part 3 consists of a storage box closing position sensor 31 and a storage box opening position sensor 32, wherein the storage box closing position sensor 31 and the storage box opening position sensor 32 are connected to the third aviation aluminum substrate 14 in the parts positioning and substrate part 1 by bolts.

[0010] The aforementioned part positioning and base plate part 1, storage box opening-closing mechanism part 2, and storage box opening-closing position sensor part 3 can all operate stably in an environment ranging from -30℃ to +80℃. Furthermore, the entire storage box fatigue fixture is lightweight, has low requirements for the testing site, and has a simple and reliable structure, meeting various stringent testing conditions.

This is one cycle. The number of times this cycle is repeated according to the test requirements is set.
