Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Fig. 1 is a structural diagram of a high-voltage explosion-proof zinc-manganese dioxide battery according to an embodiment of the invention.
A high-voltage explosion-proof zinc-manganese battery 10, comprising: the explosion-proof component comprises a steel shell 100, a conductive rod 200, an explosion-proof component 300, an elastic piece 400 and a negative bottom pad 500, wherein the steel shell 100 is of a hollow structure with an opening at one end and a closed end, the opening end of the steel shell 100 and the negative bottom pad 500 are closed to form an accommodating cavity 600, the explosion-proof component 300 and the conductive rod 200 are accommodated in the accommodating cavity 600, and the conductive rod 200 abuts against the negative bottom pad 500. In this embodiment, the steel can 100 has a cylindrical shape. The elastic member 400 is a spring.
The explosion-proof assembly 300 includes: the sealing gasket 310, the extrusion plate 320, the sealing ring 330 and the top plate 340, wherein two ends of the sealing gasket 310 are respectively connected with the extrusion plate 320 and the sealing gasket 310, one surface of the sealing gasket 310 is provided with a groove 311 with a certain inclination angle, the other surface of the sealing gasket 310 is connected with the top plate 340, the top plate 340 has a certain radian and is abutted against the conducting rod 200, the extrusion plate 320 is extruded between the inner wall of the steel shell 100 and the negative bottom pad 500, and the sealing ring 330 is sleeved on the conducting rod 200. In the present embodiment, the sealing pad 310 is an insulating pad. The pressing plate 320 is an insulating plate.
One end of the elastic member 400 is connected to the negative electrode base 500, and the other end of the elastic member 400 is connected to the conductive rod 200.
It is noted that, during the use of the zn-mn cell, the temperature inside the cell rises, the electrolyte generates gas, the pressure inside the zn-mn cell gradually increases with time, and when the internal pressure reaches a certain level, the internal pressure presses the groove 311 of the gasket 310, so that the gasket 310 is rapidly pressed outward. The sealing pad 310 pressing outwards drives the top plate 340 to press outwards, and the top plate 340 further pushes the conductive rod 200 to swing outwards, so that the conductive rod 200 is separated from the negative bottom pad 500. Thereby causing the inside of the zinc-manganese battery to be disconnected, so that the inside of the zinc-manganese battery cannot generate gas further. Wherein, when the conductive rod 200 swings outwards, the elastic member 400 is pressed to deform.
It should be further noted that, when the pressure inside the zn-mn battery is restored to a normal value, the deformed elastic member 400 is restored to its original shape, the conductive rod 200 connected to the elastic member 400 swings back, and the conductive rod 200 is electrically connected to the negative electrode base 500. Thereby leading the zinc-manganese battery to recover normal power supply.
Compared with the prior art, the invention has the following advantages:
according to the high-voltage explosion-proof zinc-manganese battery 10, the liquid leakage problem of the zinc-manganese battery is solved through the arrangement of the steel shell 100, the current conducting rod 200, the explosion-proof assembly 300, the elastic piece 400 and the negative electrode bottom pad 500. And when the internal pressure of the zinc-manganese battery reaches a certain threshold value, the internal of the zinc-manganese battery is automatically opened, so that the zinc-manganese battery is prevented from explosion, and the use safety of the zinc-manganese battery is improved. And when the internal pressure of the zinc-manganese charged battery returns to normal, the zinc-manganese charged battery returns to normal power supply.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that various changes and modifications can be made by those skilled in the art without departing from the spirit of the invention, and these changes and modifications are all within the scope of the invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
