DETAILED DESCRIPTION

[0024] Two embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0025] First embodiment:

[0026] Figures 1-3 , Figures 5-7 A new energy battery impact resistance testing device is shown, which comprises a device frame 1, guide columns 7 are symmetrically and fixedly connected to the left and right sides of the inner end of the device frame 1, a slot 4 is formed in the upper inner wall of the device frame 1, an electric wire winder 5 is fixedly connected to the upper inner wall of the slot 4, a rope 6 is wound around the outer end of the electric wire winder 5, a lifting horizontal plate 8 is bound to the lower end of the rope 6, upper hollow guide columns 9 are symmetrically and fixedly connected to the left and right ends of the lifting horizontal plate 8, an electromagnetic block 10 is fixedly connected to the lower end of the lifting horizontal plate 8, a hammering magnetic impact surface 12 is magnetically connected to the lower end of the electromagnetic block 10, lower hollow guide columns 13 are symmetrically and fixedly connected to the left and right sides of the hammering magnetic impact surface 12, an impact platform 11 is fixedly connected to the lower inner wall of the device frame 1, side slots 16 are symmetrically formed in the left and right sides of the upper hollow guide columns 9, a plurality of buffer sponge layers 17 are arranged in the inner end of the side slots 16, a plurality of deformation mechanisms 21 are arranged on the inner side wall of the guide columns 7 from top to bottom, the deformation mechanism 21 comprises a motor 22 mounted on the inner side wall of the guide column 7, a rotating vertical rod 23 is fixedly connected to the output end of the motor 22, push pieces 24 are symmetrically and fixedly connected to the left and right sides of the rotating vertical rod 23, a plurality of cylindrical inner holes 19 are formed in the outer side of the guide column 7, L-shaped stopping rods 20 are slidably connected to the inner end of the cylindrical inner holes 19, and return springs 25 are fixedly connected between two corresponding L-shaped stopping rods 20.

[0027] Figures 1-3 , Figures 5-7It is shown that a plurality of force-dividing spring members 18 are fixedly connected between two adjacent buffer sponge layers 17, the upper hollow guide column 9 is slidably connected to the outside of the guide column 7, the lower hollow guide column 13 is slidably connected to the outside of the guide column 7, the impact platform 11 is located directly below the hammering magnetic impact surface 12, and is vertically arranged from top to bottom between the side groove 16 and the cylindrical inner hole 19 and the L-shaped stop rod 20 on the same side. The front end of the equipment frame 1 is hinged with a cabinet door 2, and the front end of the cabinet door 2 is fixedly connected to a transparent panel 3.

[0028] Figures 1-3 、 Figures 5-7 The present invention shows that the hammering magnetic impact surface 12 is placed under the lifting horizontal plate 8. The control system energizes the electromagnetic block 10 to generate a strong magnetic force to attract the hammering magnetic impact surface 12. The electric winder 5 is started to rewind the rope 6 and lift it to a predetermined height. The control system de-energizes the electromagnet, the magnetic force disappears, and the hammering magnetic impact surface 12 falls freely under the action of gravity, hitting the battery fixed on the impact platform 11, generating a huge impact force. The detection system monitors various parameters of the battery in real time during the impact process and obtains analysis results. At the same time, a buffer sponge layer 17 is provided in the side groove 16 on the hollow guide column 9 on both sides of the lifting horizontal plate 8. The multiple force-dividing spring members 18 in the buffer sponge layer 17 can make the two cooperate to form a buffer structure. After the hammering magnetic impact surface 12 falls with gravity, the electric winder 5 can quickly lower the rope 6. After lowering, the lifting horizontal plate 8 also falls freely and quickly to the hammering magnetic impact surface 12, and a deformation mechanism 21 is provided in the guide columns 7 on both sides above the hammering magnetic impact surface 12. The deformation mechanism 21 is driven by a motor 22 to rotate The dynamic vertical rod 23 rotates to make the two push pieces 24 push the two L-shaped intercepting rods 20 to the outside of the cylindrical inner hole 19, so that the upper hollow guide pillars 9 on both sides of the lifting horizontal plate 8 are limited at the L-shaped intercepting rods 20 when falling, and the side grooves 16 are used to engage with the L-shaped intercepting rods 20. The force-dividing spring member 18 and the buffer sponge layer 17 in the side grooves 16 can buffer the vertical falling impact force of the lifting horizontal plate 8, so that the lifting horizontal plate 8 falls more steadily with the hammering magnetic impact surface 12. When the lifting horizontal plate 8 falls close to the hammering magnetic impact surface 12, When one side of the lifting plate 8 is stopped by the corresponding pair of L-shaped stopping rods 20, the motor 22 rotates to make the two L-shaped stopping rods 20 retract into the cylindrical inner hole 19 through the reset spring 25, so that the small height between the lifting horizontal plate 8 and the hammering magnetic impact surface 12 is eliminated, so that the two can smoothly meet and re-establish the connection. This method can effectively reduce the waiting time for the lifting horizontal plate 8 to re-establish the connection with the hammering magnetic impact surface 12, and facilitates the rapid reset and lifting of the lifting horizontal plate 8 to the specified height for multiple impact tests, effectively ensuring the best experimental efficiency.
