First embodiment:
referring to fig. 1 to 5, fig. 5 is a cross-sectional view of a battery according to a first embodiment of the present application.
In the battery 200 provided in the first embodiment of the present application, the battery housing assembly 100 includes a housing body 10, a cover 20 and a terminal 30, the housing body 10 is provided with an opening 11, the housing body 10 includes a bottom plate 12 and a side plate 13 integrally formed, and the bottom plate 12 has a through hole 121. The cover plate 20 is arranged at the opening 11 of the shell body 10 in a covering way, and the cover plate 20 is arranged opposite to the bottom plate 12. The terminals 30 are mounted on the base plate 12 and pass through the through holes 121.
In the battery case assembly 100 provided in this embodiment, the through holes 121 are formed in the bottom plate 12 of the case body 10, and the through holes 121 of the bottom plate 12 are used for mounting the terminals 30. Because the bottom plate 12 and the side plate 13 are integrally formed, the structural strength of the bottom plate 12 is high, and after the terminal 30 is arranged on the bottom plate 12, the bottom plate 12 and the shell body 10 assembly are not easy to deform, so that the overall structural strength of the battery shell assembly 100 is high, and the structural stability of the battery shell assembly 100 is improved. Meanwhile, the battery shell assembly 100 has a strong structure and is not easy to deform, so that the stability of the electrical connection of the internal structure of the battery shell assembly 100 can be reduced, and the quality of the battery 200 formed by the battery shell assembly 100 in the use process can be improved.
Specifically, the bottom plate 12 and the side plate 13 of the case body 10 enclose a receiving chamber 14, and the pole core 40 of the battery 200 is received in the receiving chamber 14. The electrode core 40 includes a first electrode tab 41 and a second electrode tab 42, the first electrode tab 41 is electrically connected to the cover 20, and the second electrode tab 42 is electrically connected to the terminal 30.
It should be understood that, in the battery 200 provided in the present embodiment, the first tab 41 of the electrode core 40 is electrically connected to the cover 20 through the electrical connection piece, and the second tab 42 of the electrode core 40 is electrically connected to the terminal 30 through the electrical connection piece. In some other embodiments, the second tab 42 of the pole core 40 may abut against the terminal 30 to form an electrical connection, and an electrical connection pad between the second tab 42 and the terminal 30 may be omitted, which is not limited in the present application.
In a specific embodiment, the terminal 30 of the battery case assembly 100 is insulated from the base plate 12, and the first tab 41 and the second tab 42 of the pole core 40 are insulated from each other by the terminal 30 and the base plate 12, so as to prevent the pole core 40 from being shorted.
In a specific embodiment, the terminal 30 includes a first portion 31 and a second portion 32 that are connected together, and the first portion 31 and the second portion 32 are integrally formed to form the terminal 30. The first portion 31 is disposed through the through hole 121 of the base plate 12 and electrically connected to the second tab 42 of the pole core 40, and the first portion 31 is disposed in an insulating manner with respect to the base plate 12. The second portion 32 is disposed on a side of the base plate 12 facing away from the cover plate 20, and the second portion 32 is disposed in an insulated relationship with the base plate 12. Through the first portion 31 of the terminal 30 is electrically connected with the second lug 42 of the pole core 40 after penetrating the through hole 121, and the first portion 31 and the second portion 32 of the terminal 30 are both arranged in an insulating manner with the bottom plate 12, the terminal 30 is not electrically connected with the shell body 10 after being electrically connected with the pole core 40, and the second lug 42 of the pole core 40, the shell body 10 and the cover plate 20 can be prevented from being electrically connected, so that the battery 200 formed by the battery shell assembly 100 and the pole core 40 is prevented from being short-circuited.
Further, a gap is formed between the peripheral side wall of the first portion 31 and the inner side wall of the through hole 121. The gap is an annular gap for accommodating insulation such that the first portion 31 is disposed insulated from the base plate 12. By forming a gap between the peripheral side wall of the first portion 31 and the inner side wall of the through hole 121 for accommodating an insulator so that the first portion 31 is arranged insulated from the bottom plate 12 of the case body 10, it is possible to prevent the second tab 42 of the pole core 40 from being electrically connected to the bottom plate 12 through the first portion 31.
Illustratively, taking the example of the first portion 31 being cylindrical and the through-hole 121 being a circular hole, the radial dimension of the first portion 31 is smaller than the radial dimension of the through-hole 121, i.e., the diameter of the first portion 31 is smaller than the diameter of the through-hole 121, whereby an annular gap can be formed between the peripheral side wall of the first portion 31 and the inner side wall of the through-hole 121.
It should be appreciated that in some other embodiments, the shape of the first portion 31 of the terminal 30 includes, but is not limited to, a pyramid, a cone, a truncated cone, etc., and the shape of the through hole 121 includes, but is not limited to, a tapered hole, an elliptical hole, a polygonal hole, etc., as long as it is ensured that an annular gap is formed between the peripheral sidewall of the terminal 30 and the inner sidewall of the through hole 121, which is not limited by the present application.
It will be appreciated that the radial dimensions of the first portion 31 of the terminal 30 may be set according to the overall dimensions of the battery 200, as the application is not limited in this respect. Illustratively, when the battery housing assembly 100 is applied to a button cell, the diameter of the first portion 31 of the terminal 30 ranges from [1,10] mm.
Further, the orthographic projection of the second portion 32 on the bottom plate 12 covers the through hole 121, and the outer peripheral edge of the second portion 32 is located between the outer peripheral edge of the opening of the through hole 121 and the outer peripheral edge of the bottom plate 12. Taking the example of the base plate 12 having a cylindrical shape, the second portion 32 having a cylindrical shape, and the through hole 121 having a circular shape, the radial dimension of the second portion 32 is larger than the radial dimension of the through hole 121, and the radial dimension of the second portion 32 is smaller than the radial dimension of the base plate 12. In other words, the diameter of the second portion 32 is greater than the diameter of the through hole 121, and the diameter of the second portion 32 is smaller than the diameter of the bottom plate 12.
The through-hole 121 is covered by the orthographic projection of the second portion 32 on the bottom plate 12, and the outer peripheral edge of the second portion 32 is located between the outer peripheral edge of the opening of the through-hole 121 and the outer peripheral edge of the bottom plate 12 to enable the terminal 30 to be held against the bottom plate 12, thereby enabling the terminal 30 to be mounted at the through-hole 121 of the bottom plate 12. The outer peripheral edge of the opening of the through-hole 121 is positioned between the outer peripheral edge of the opening of the second portion 32 and the outer peripheral edge of the bottom plate 12 so that the terminal 30 is mounted on the bottom plate 12 without exposing the bottom plate 12, thereby making the outer appearance of the battery case assembly 100 more attractive.
In this embodiment, the second portion 32 of the terminal 30 has a cylindrical shape, and the through hole 121 has a circular hole. The second portion 32 of the terminal 30 has a diameter greater than the diameter of the through hole 121 so that the terminal 30 can be mounted at the through hole 121 of the base plate 12 and form an abutment with the base plate 12. The bottom plate 12 has a cylindrical plate shape, and the diameter of the second portion 32 is smaller than the diameter of the bottom plate 12, that is, the diameter of the second portion 32 is equal to or smaller than 1 of the bottom plate 12, so that the appearance of the battery case assembly 100 is more attractive.
It should be appreciated that in some other embodiments, the shape of the second portion 32 of the terminal 30 includes, but is not limited to, a pyramid, a cone, a truncated cone, etc., and the shape of the through hole 121 includes, but is not limited to, a tapered hole, an elliptical hole, a polygonal hole, etc., just to ensure that the second portion 32 of the terminal 30 is capable of abutting the base plate 12, as the application is not limited in this respect.
In a particular embodiment, the battery housing assembly 100 further includes a connector 50, the connector 50 being disposed between the second portion 32 and the base plate 12. The attachment member 50 is adhesive and the attachment member 50 is used to attach the second portion 32 to the base 12. The connector 50 is also insulative, and the connector 50 also serves to provide insulation between the second portion 32 and the base plate 12.
More specifically, the connecting piece 50 provided in this embodiment is a hot melt adhesive, and the material includes, but is not limited to, a thermoplastic or thermosetting material such as polypropylene (Po lypropy lene, PP). By disposing the connection member 50 between the second portion 32 and the base plate 12 so as to insulate the second portion 32 of the terminal 30 from the base plate 12, the battery 200 formed by the battery case assembly 100 and the pole piece 40 can be prevented from being shorted. Moreover, the connector 50 also serves to connect the second portion 32 of the terminal 30 to the base plate 12 for better stability of the mounting of the terminal 30 to the base plate 12. At the same time, the connector 50 is also capable of sealing the second portion 32 of the terminal 30 and the base plate 12 to provide a better seal of the battery housing assembly 100 and the battery 200 as a whole formed by the battery housing assembly 100 and the pole piece.
It will be appreciated that the connector 50 is also in contact with the first portion 31 of the terminal 30, and when the second portion 32 presses the connector 50, the connector 50 can be filled into the gap between the peripheral side wall of the first portion 31 of the terminal 30 and the inner side wall of the through hole 121 after pressing, so as to provide insulation between the first portion 31 of the terminal 30 and the base plate 12.
Further, the outer peripheral edge of the connector 50 is located between the outer peripheral edge of the second portion 32 and the outer peripheral edge of the base plate 12. Taking the example of the connecting member 50 having a circular shape, the second portion 32 having a cylindrical shape, and the base plate 12 having a cylindrical shape, the radial dimension of the connecting member 50 is greater than the radial dimension of the second portion 32, and the radial dimension of the connecting member 50 is less than the radial dimension of the base plate 12. In other words, the outer diameter of the connector 50 is greater than the diameter of the second portion 32, and the outer diameter of the connector 50 is less than the diameter of the base plate 12.
In this embodiment, the outer peripheral edge of the connecting member 50 is located between the outer peripheral edge of the second portion 32 and the outer peripheral edge of the base plate 12, so that the diameter of the connecting member 50 is larger than that of the second portion 32, that is, the orthographic projection of the peripheral edge of the second portion 32 on the connecting member 50 is completely located on the connecting member 50, so that the second portion 32 of the terminal 30 can be completely turned over by the connecting member 50 near one side of the base plate 12, which is beneficial to improving the connection stability and insulation stability between the second portion 32 of the terminal 30 and the base plate 12. In this embodiment, by locating the peripheral edge of the connecting member 50 between the peripheral edge of the second portion 32 and the peripheral edge of the bottom plate 12, the diameter of the connecting member 50 is smaller than the diameter of the bottom plate 12, i.e., the orthographic projection of the peripheral edge of the connecting member 50 on the bottom plate 12 is completely located on the bottom plate 12, so that the peripheral edge of the bottom plate 12 is not exposed by the connecting member 50, thereby making the structure of the battery 200 more beautiful.
Second embodiment:
Referring to fig. 6, fig. 6 is a cross-sectional view of a battery according to a second embodiment of the present application.
The battery case assembly 100 in the battery 200 according to the second embodiment of the present application is substantially the same as the battery case assembly 100 in the battery 200 according to the first embodiment of the present application, except that in the battery case assembly 100 in the battery 200 according to the second embodiment of the present application, the battery case assembly 100 further includes an insulating member 60, the insulating member 60 is disposed on a side of the bottom plate 12 near the cover plate 20, and the first portion 31 penetrates through the insulating member 60 and is electrically connected to the second tab 42. By the provision of the insulating member 60, in the battery 200 formed by the battery case assembly 100 and the pole core 40, the second tab 42 of the pole core 40 can be prevented from contacting the base plate 12, and thus the second tab 42 of the pole core 40 can be provided with insulation from the base plate 12.
Third embodiment:
Referring to fig. 7, fig. 7 is a cross-sectional view of a battery according to a third embodiment of the present application.
The battery case assembly 100 in the battery 200 provided by the third embodiment of the present application is substantially the same as the battery case assembly 100 in the battery 200 provided by the first embodiment of the present application, except that the terminal 30 mounting direction of the battery case assembly 100 in the battery 200 provided by the third embodiment of the present application is different.
In the battery case assembly 100 of the battery 200 according to the third embodiment of the present application, the terminal 30 includes the first portion 31 and the second portion 32 that are connected. The first portion 31 is disposed through the through hole 121, and is disposed in an insulating manner between the first portion 31 and the bottom plate 12. The second portion 32 is disposed on a side of the base plate 12 near the cover plate 20, the second portion 32 is electrically connected to the second tab 42, and the second portion 32 is disposed in an insulating manner with respect to the base plate 12.
According to the battery case assembly 100 of the battery 200 provided in this embodiment, the first portion 31 and the second portion 32 of the terminal 30 are integrally mounted on the case body 10, and the bottom plate 12 and the side plate 13 are integrally formed, so that the structural strength of the bottom plate 12 is high, and after the terminal 30 is mounted on the bottom plate 12, the bottom plate 12 and the case body 10 are not easy to deform, so that the structural strength of the battery case assembly 100 and the battery 200 is high, and the structural stability of the battery case assembly 100 and the battery 200 is improved. Meanwhile, the battery case assembly 100 and the battery 200 have strong and large structures and are not easy to deform, so that the stability of the electrical connection of the internal structure of the battery 200 formed by the battery case assembly 100 and the pole core 40 can be reduced, and the quality of the battery 200 in the use process can be improved.
In a specific embodiment, the battery housing assembly 100 of the battery 200 further includes a connector 50, the connector 50 being disposed between the second portion 32 and the base plate 12. The connector 50 is used to connect the second portion 32 to the base plate 12, and the connector 50 is also used to provide insulation between the second portion 32 and the base plate 12. By disposing the connection member 50 between the second portion 32 and the base plate 12 so as to insulate the second portion 32 of the terminal 30 from the base plate 12, the battery 200 formed by the battery case assembly 100 and the pole piece 40 can be prevented from being shorted. Moreover, the connector 50 also serves to connect the second portion 32 of the terminal 30 to the base plate 12 for better stability of the mounting of the terminal 30 to the base plate 12. Meanwhile, the connection member 50 can also seal the second portion 32 of the terminal 30 and the bottom plate 12, so that the battery case assembly 100 and the battery 200 formed by the battery case assembly 100 and the electrode core 40 have a better sealing effect as a whole.
Further, the outer peripheral edge of the connector 50 is located between the outer peripheral edge of the second portion 32 and the outer peripheral edge of the base plate 12. Taking the example of the connecting member 50 having a circular shape, the second portion 32 having a cylindrical shape, and the base plate 12 having a cylindrical shape, the radial dimension of the connecting member 50 is greater than the radial dimension of the second portion 32, and the radial dimension of the connecting member 50 is less than the radial dimension of the base plate 12. In other words, the outer diameter of the connector 50 is greater than the diameter of the second portion 32, and the outer diameter of the connector 50 is less than the diameter of the base plate 12. On the one hand, the diameter of the outer circle of the connecting piece 50 is larger than that of the second part 32, and the second part 32 of the terminal 30 is completely turned over on the side close to the bottom plate 12 through the connecting piece 50, so that the connection stability and the insulation stability between the second part 32 of the terminal 30 and the bottom plate 12 are improved. On the other hand, the outer diameter of the connecting member 50 is smaller than the diameter of the bottom plate 12, and the connecting member 50 does not expose the periphery of the bottom plate 12, so that the battery case assembly 100 and the battery 200 formed by the battery case assembly 100 and the electrode core are more attractive in structure.
Still further, the orthographic projection of the second portion 32 on the bottom plate 12 covers the through hole 121, and the outer peripheral edge of the second portion 32 is located between the outer peripheral edge of the opening of the through hole 121 and the outer peripheral edge of the bottom plate 12. Taking the example of the base plate 12 having a cylindrical shape, the second portion 32 having a cylindrical shape, and the through hole 121 having a circular shape, the radial dimension of the second portion 32 is larger than the radial dimension of the through hole 121, and the radial dimension of the second portion 32 is smaller than the radial dimension of the base plate 12. In other words, the diameter of the second portion 32 is greater than the diameter of the through hole 121, and the diameter of the second portion 32 is smaller than the diameter of the bottom plate 12.
The through-hole 121 is covered by the orthographic projection of the second portion 32 on the bottom plate 12, and the outer peripheral edge of the second portion 32 is located between the outer peripheral edge of the opening of the through-hole 121 and the outer peripheral edge of the bottom plate 12 to enable the terminal 30 to be held against the bottom plate 12, thereby enabling the terminal 30 to be mounted at the through-hole 121 of the bottom plate 12. The outer peripheral edge of the opening of the through-hole 121 is positioned between the outer peripheral edge of the opening of the second portion 32 and the outer peripheral edge of the bottom plate 12 so that the terminal 30 is mounted on the bottom plate 12 without exposing the bottom plate 12, thereby making the outer appearance of the battery case assembly 100 more attractive.
While the foregoing is directed to embodiments of the present application, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the application, and such changes and modifications are intended to be included within the scope of the application.
