As shown in fig. 1, which is a schematic structural diagram of a vibration fixture of a lithium battery plug box provided by the present invention. The vibration fixture is used for clamping and fixing a lithium battery plug box 10 for vibration test. The lithium battery box 10 itself is prior art and includes an outer frame and a lithium battery pack disposed in the outer frame. The lithium battery box 10 is not an innovative point of the present invention and will not be described in detail herein. The vibration fixture of lithium battery plug-in box includes a shaking table 20 of setting on vibration testing machine, and four settings are in on the shaking table 20 and be located respectively lithium battery plug-in box 10's L shape roof 21 all around to and a plane clamp plate 22 of setting on two relative L shape roofs 21 that set up. It is conceivable that the vibration jig is integrally provided on a vibration testing machine, and the vibration testing machine itself is a prior art and will not be described in detail herein.

The vibration table 20 has a planar structure. For the purpose of improving the accuracy of the vibration test, the accuracy of the flatness of the table top of the vibration table 20 should be high, and it is preferable that the flatness of the vibration table 20 is less than 1. In addition, it will be appreciated that the vibration table 20 itself may be a component of the vibration testing machine.

The four L-shaped top plates 21 should be symmetrically arranged so as to be balanced with each other in all directions when vibrated. The four said L-shaped top plates 21 have the same structure and dimensions. Only one of which is described herein. The L-shaped top plate 21 includes a first plate 211 fixedly disposed on the vibration table 20, a second plate 212 fixedly connected to the first plate 211 and abutting against the lithium battery compartment 10, a rib 213 disposed between the first plate 211 and the second plate 212, a plurality of rows of fastener passing grooves 214 disposed on the first plate 211, and a plurality of fasteners 215 respectively passing through the fastener passing grooves 214 and fixed on the vibration table 20.

The first and second plates 211, 212 are both flat plate structures, and the flatness of their contact surfaces with the lithium battery box 10 and the vibration table 20 should also be high to improve the test accuracy. In this embodiment, the flatness of the surfaces of the first and second plates 211 and 212 contacting the lithium battery box 10 and the vibration table 20 is less than 1. The first and second plates 211 and 212 may be formed by welding or may be integrally formed. In this embodiment, the first and second plates 211, 212 are integrally formed, such as by bending. The thicknesses of the first and second plates 211, 212 can be selected according to actual requirements, such as the magnitude of the first-order natural vibration frequency of the whole vibration jig.

The reinforcing ribs 213 are disposed on the middle lines of the first and second plates 211, 212 to achieve the purpose of symmetrical arrangement. The reinforcing ribs 213 may be formed on the first and second plates 211 and 212 by welding.

The multiple rows of the fastener through grooves 214 are distributed on two sides of the reinforcing rib 213 and are symmetrically distributed. The extending direction of the fastener through groove 214 is parallel to the arrangement direction of the two oppositely arranged L-shaped top plates 21, so that the mass of the vibration table 20 is symmetrically distributed. In this embodiment, four fastener passing grooves 214 are formed in the first plate 211, and two of the four fastener passing grooves 214 are symmetrically distributed on two sides of the reinforcing rib 213. In order to improve the compatibility of the vibration jig, the two fastener insertion grooves 214 on the side of the reinforcing rib 213 are not equally spaced from the second plate 212 at the minimum distance, which is also advantageous in adjusting the first-order natural frequency of the vibration jig.

The fastening member 215 is used to fix the first plate 211 to the vibration table 20. The fasteners 215 are preferably bolted in order to secure the mounting of the entire vibration jig. The fastener 215 is per se prior art and will not be described in further detail herein. The number of the fastening members 215 can be set according to actual requirements, such as the required first-order natural vibration frequency.

The planar pressing plates 22 are disposed on the two oppositely disposed L-shaped top plates 21 to press the lithium battery box 10, thereby fixing the lithium battery box 10. In order to improve the compatibility of the vibration clamp, the planar pressing plate 22 may also be in a groove shape, so that two edges of the planar pressing plate 22 in the groove shape structure are adjusted to adapt to lithium battery plug-in boxes 10 with different heights.

Compared with the prior art, the vibration clamp of the lithium battery plug-in box provided by the utility model fully utilizes the vibration table 20, and clamps the lithium battery plug-in box 10 in combination with the four L-shaped top plates 21 which are symmetrically arranged and the plane pressing plate 22, so as to achieve the purpose of fixing the lithium battery plug-in box 10. The L-shaped top plate 21 is formed of first and second plates 211 and 212 perpendicular to each other, and the first plate 211 is variably fixed to the vibration table 20 by means of a fixing member 215, so that compatibility of the L-shaped top plate 21 can be improved, and the first and second plates 211 and 212 have a simple structure, so that it is sufficient to increase the thickness thereof when designing the first-order natural frequency thereof. Of course, if the first-order natural frequency of the first and second plates 211, 212 cannot be satisfied by increasing the thickness, the number of the fastening members 215 between the first plate 211 and the vibration table 20 can be increased, which is favorable for improving the compatibility of the vibration jig and reducing the difficulty of designing the vibration jig.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
