Test apparatus including a fixing jig for vibration test of battery pack
View Patent ↗Provided is a test apparatus including a fixing jig for vibration test of a battery pack. The fixing jig includes at least one upper block that is coupled to at least one coupler formed in the battery pack, a lower block placed below the at least one upper block, and a base plate having a board shaped and placed below the lower block.
1. A test apparatus comprising a fixing jig for vibration testing of a battery pack, wherein the fixing jig comprises:
at least one upper block that is coupled to at least one coupler of the battery pack;
a lower block below the at least one upper block; and
a base plate having a board shape and below the lower block,
wherein a lower surface of the lower block has an entire flat shape to allow surface contact with an upper surface of the base plate,
wherein a plurality of main protrusions that protrudes higher than a second area of an upper part of the lower block is in a first area of an upper part of the lower block, and
wherein the plurality of main protrusions provides a step structure to support bottom of two ends of each upper block.
2. The test apparatus according to claim 1 , wherein each upper block has at least one guide groove corresponding to a shape of an upper part of each coupler.
3. The test apparatus according to claim 2 , wherein each upper block is fixed to each coupler by a bolt inserted in vertical direction in a state that each upper block is in contact with the upper part of each coupler through each guide groove.
4. The test apparatus according to claim 1 , wherein the lower block has a plurality of stoppers to support one side surface of each end of each upper block through surface contact.
5. The test apparatus according to claim 4 , wherein each stopper is fixed to each upper block by a bolt inserted in horizontal direction in a state that each stopper is in surface contact with the side surface of one end of each upper block.
6. The test apparatus according to claim 1 , wherein at least one secondary protrusion that protrudes higher than the second area is in a third area of an upper part of the lower block, and
a central part between the two ends of the at least one upper block is supported by each secondary protrusion.
7. The test apparatus according to claim 1 , further comprising:
a vibration generator coupled to part of the base plate to generate vibration in a preset pattern.
8. The test apparatus according to claim 7 , wherein the base plate is fixed to the vibration generator by a bolt inserted in vertical direction in a state that the base plate is in surface contact with an upper surface of the vibration generator.
