Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a lithium ion battery assembly vibration test fixture as shown in figures 1-4, including installed part 1, support piece 2, installation piece 3 and lithium battery assembly 6, three rows of first mounting holes 101 have been seted up at least to the surface of installed part 1, first mounting holes 101 have evenly been seted up in proper order to the surface of two installed parts 1, the top of two support pieces 2 is equipped with protruding limit 201, the surface of two support pieces 2 has evenly been seted up in proper order second mounting hole 203, two support pieces 2 cooperate the bolt through base 202 that sets up in the below and set up first mounting hole 101 fixed connection on installed part 1;
The lithium battery assembly 6 is fixedly connected with the upper shell base body 5 and the lower shell base body 4 through a fourth mounting hole 401 arranged on the lower shell base body 4 and a matched bolt with the supporting piece 2; meanwhile, in the assembling process, when the end surface of the lower base body 4 of the shell is too close to the support piece 2, the lower base body 4 of the shell and the support piece 2 may have friction risk during vibration test, and the test effect of the lithium battery assembly 6 is affected to a certain extent, so that the distance between the end surfaces of the two sides of the lower base body 4 of the shell and the surface of the support piece 2 is 3 mm-5 mm which is the optimal distance.
And in anchor clamps assembling process, considering that base member 4 is too little to appear the product collision danger from installed part 1 apart from under the shell that is used for placing lithium cell assembly 6, base member 4 is different from installed part 1 apart from frequency when too big can cause the vibration of each position of product under the shell, influence the experimental result, this is experimental many times according to multiple product, interval scope is 30mm ~ 50mm between base member 4 and the installed part 1 under the shell is suitable, the chute has been seted up on the surface of base member 4 in fourth mounting hole 401 department under the shell simultaneously. Can reduce the possibility of friction between the lower base body 4 of the shell and the supporting piece 2 and is convenient for assembling bolts by utilizing a chute structure
Two sides of the two mounting blocks 3 are respectively provided with a thread groove 301, the top of the mounting block 3 is provided with a third mounting hole 302, the mounting block 3 is fixedly connected with the transverse pull rod 7 through the bolt-fit third mounting hole 302, and the mounting block 3 and the transverse pull rod 7 are integrated and fixed through the bolt-fit thread groove 301 and a second mounting hole 203 arranged on the raised edge 201 in a threaded manner.
The working principle is that when clamping is carried out, the fixed relation between the lithium battery assembly 6 and the upper shell matrix 5 and the lower shell matrix 4 of the battery is firstly ensured. The lithium battery assembly 6, the upper shell base body 5 of the battery and the lower shell base body 4 of the battery are integrated to penetrate through the two fourth mounting holes 401 arranged on the lower shell base body 4 through bolts and are respectively connected with the two supporting pieces 2, and then the two supporting pieces 2 are sequentially assembled on the surfaces of the two mounting pieces 1 through the bolt matched second mounting holes 203 and the first mounting holes 101.
In concrete operation process, considering that the distance between the lower base body 4 of the shell for placing the lithium battery assembly 6 and the mounting part 1 is too small and the product collision danger is likely to occur, the frequency is different when the distance between the lower base body 4 of the shell and the mounting part 1 is too large and the vibration of each part of the product is likely to be caused, the experimental result is influenced, the interval range between the lower base body 4 of the shell and the mounting part 1 is 30 mm-50 mm according to multiple tests of multiple products. Meanwhile, in the assembling process, when the end surface of the lower base body 4 of the shell is too close to the support piece 2, the lower base body 4 of the shell and the support piece 2 may have friction risk during vibration test, and the test effect of the lithium battery assembly 6 is affected to a certain extent, so that the distance between the end surfaces of the two sides of the lower base body 4 of the shell and the surface of the support piece 2 is 3 mm-5 mm which is the optimal distance.
Through this kind of mode, make lithium battery assembly 6 play the effect that the suspension type is connected, and to lithium battery assembly 6's assembly according to strict screening and test, select optimum installation interval and position, make lithium battery assembly 6 can the at utmost restore the mounting means on whole car, make lithium battery assembly 6 can carry out vibration test with real installation status to this accuracy of guaranteeing experimental effect has improved the referential of test result.
