In view of this, the utility model provides a lithium battery expansion phenomenon demonstration device to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0025] like Figure 1-Figure 2 As shown, a lithium battery expansion phenomenon demonstration device provided by an embodiment of the utility model includes a support base 1, a first clamping panel 3, a battery housing 4 and a second clamping panel 5 are arranged on the surface of the support base 1, and the sides of the first clamping panel 3 and the second clamping panel 5 close to each other are respectively installed with a telescopic spring 2 and a pressure sensor 7, and the battery housing 4 is placed between the telescopic spring 2 and the pressure sensor 7. It can be understood that the first clamping panel 3, the second clamping panel 5 and the battery housing 4 are placed on the surface of the support base 1, and they are not fixedly connected to the support base 1;

[0026] The first clamping panel 3 and the second clamping panel 5 are both made of transparent materials, and the battery housing 4 is made of aluminum-based materials, so that the observer can carefully observe the expansion and contraction changes of the telescopic spring 2 through the first clamping panel 3, and by making the battery housing 4 of aluminum-based materials, the battery housing 4 can have good elasticity;

[0027] The surface of the battery housing 4 is provided with a first through hole 9 and a second through hole 13 , and the interior of the second through hole 13 is connected with a sealing plug 8 , and the outer diameter of the sealing plug 8 is the same as the caliber of the second through hole 13 .

[0028] In one embodiment of the utility model, when the device is used to demonstrate the expansion phenomenon of a lithium battery, the battery housing 4 is first placed between the telescopic spring 2 and the pressure sensor 7, that is, the end of the telescopic spring 2 away from the first clamping panel 3 is against the surface of the battery housing 4, and the surface of the pressure sensor 7 away from the second clamping panel 5 is in contact with the surface of the battery housing 4, and then the sealing plug 8 is inserted into the second through hole 13, and a sphere simulating a lithium electron is placed into the battery housing 4 through the first through hole 9. It can be understood that during this process, the battery housing 4 will expand, and when the housing expands to a certain extent, the sealing plug 8 inside the second through hole 13 is removed, and the spheres are taken out one by one from the inside of the battery housing 4;

[0029] During the above working process, the observer can observe the expansion and contraction changes of the telescopic spring 2 through the first clamping panel 3, and understand the expansion phenomenon of the battery shell 4 through the expansion and contraction changes of the telescopic spring 2. In addition, through the pressure sensor 7, the force generated when the battery shell 4 expands can be further understood, so that the observer can feel the expansion phenomenon of the lithium battery more intuitively.

[0030] Preferably, the pressure sensor 7 is a diaphragm strain pressure sensor, a display screen 6 is mounted on the surface of the support base 1, and the display screen 6 is electrically connected to the pressure sensor 7, so that an observer can understand the force generated when the battery housing 4 expands in real time through the display screen 6.

[0031] Preferably, the center point of the battery housing 4 is located on the axis of the telescopic spring 2 , so that the squeezing force of the telescopic spring 2 on the battery housing 4 can be distributed more evenly on the battery housing 4 .

[0032] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, a connection component is commonly provided on the surfaces of the first clamping panel 3 and the second clamping panel 5, and the connection component is used to detachably connect the first clamping panel 3 and the second clamping panel 5 together.

[0033] The connection components include:

[0034] A plurality of second threaded connection holes 14 are formed on the surface of the first clamping panel 3, and a plurality of first threaded connection holes 12 are formed on the surface of the second clamping panel 5. The first threaded connection holes 12 and the second threaded connection holes 14 have the same aperture, and the first threaded connection holes 12 and the second threaded connection holes 14 are mutually meshed and connected with threaded connection rods 10;

[0035] A twist handle 11 is provided at one end of the threaded connecting rod 10 .

[0036] In this embodiment, when it is necessary to disassemble the first clamping panel 3 and the second clamping panel 5 to respectively maintain and clean the first clamping panel 3, the telescopic spring 2, the second clamping panel 5 and the pressure sensor 7, the staff can hold the twisting handle 11 by hand and turn the twisting handle 11 out of the second threaded connection hole 14 opened on the surface of the first clamping panel 3 and the first threaded connection hole 12 opened on the surface of the second clamping panel 5, so that the first clamping panel 3 and the second clamping panel 5 are no longer restricted together, so as to improve the convenience of use of the lithium battery expansion phenomenon demonstration device.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
