Among them, the shell body 10, the cover plate 20, the terminal 30, the connector 50 and the insulating member 60 are combined to form the above-mentioned battery housing assembly 100. The shell body 10 has an opening 11, the cover plate 20 is covered at the opening 11 of the shell body 10, the pole core 40 is accommodated in the shell body 10, the terminal 30 is installed on the shell body 10, the terminal 30 and the cover plate 20 are arranged at opposite ends of the shell body 10, the connector 50 is arranged outside the shell body 10, the connector 50 is arranged between the shell body 10 and the terminal 30, and the insulating member 60 is arranged in the shell body 10.

[0040] First embodiment:

[0041] See also Figures 1 to 5 , Figure 5 It is a cross-sectional view of a battery provided in the first embodiment of the present application.

[0042] 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 plate 20 and a terminal 30. The housing body 10 is provided with an opening 11. The housing body 10 includes an integrally formed bottom plate 12 and a side plate 13. The bottom plate 12 has a through hole 121. The cover plate 20 covers the opening 11 of the housing body 10, and the cover plate 20 is arranged opposite to the bottom plate 12. The terminal 30 is mounted on the bottom plate 12 and penetrates the through hole 121.

[0043] The battery shell assembly 100 provided in this embodiment has a through hole 121 formed on the bottom plate 12 of the shell body 10, and the through hole 121 of the bottom plate 12 is used to install the terminal 30. Since the bottom plate 12 and the side plate 13 are integrally formed, the structural strength of the bottom plate 12 is relatively large. After the terminal 30 is installed on the bottom plate 12, the bottom plate 12 and the shell body 10 assembly are not easily deformed, thereby making the overall structural strength of the battery shell assembly 100 relatively large, which is beneficial to improving the structural stability of the battery shell assembly 100. At the same time, the structural strength of the battery shell assembly 100 is relatively large and not easy to deform, which can reduce the stability of the electrical connection of the internal structure of the battery shell assembly 100, thereby improving the quality of the battery 200 formed by the battery shell assembly 100 during use.

[0044] Specifically, the bottom plate 12 and the side plate 13 of the shell body 10 are arranged to form a receiving cavity 14, and the pole core 40 of the battery 200 is received in the receiving cavity 14. The pole core 40 includes a first pole tab 41 and a second pole tab 42, the first pole tab 41 is electrically connected to the cover plate 20, and the second pole tab 42 is electrically connected to the terminal 30.

[0045] It should be understood that in the battery 200 provided in this embodiment, the first pole ear 41 of the pole core 40 is electrically connected to the cover plate 20 through the electrical connection sheet, and the second pole ear 42 of the pole core 40 is electrically connected to the terminal 30 through the electrical connection sheet. In some other embodiments, the second pole ear 42 of the pole core 40 can be abutted against the terminal 30 to form an electrical connection, and the electrical connection sheet between the second pole ear 42 and the terminal 30 can be omitted, and the present application does not limit this.

[0046] In a specific embodiment, the terminal 30 of the battery housing assembly 100 is insulated from the bottom plate 12 to prevent the first pole ear 41 and the second pole ear 42 of the pole core 40 from being electrically connected and causing a short circuit in the pole core 40 by insulating the terminal 30 from the bottom plate 12.

[0047] In a specific embodiment, the terminal 30 includes a first part 31 and a second part 32 connected and arranged, and the first part 31 and the second part 32 are integrally formed to form the terminal 30. The first part 31 passes through the through hole 121 of the bottom plate 12 and is electrically connected to the second pole ear 42 of the pole core 40, and the first part 31 is insulated from the bottom plate 12. The second part 32 is arranged on the side of the bottom plate 12 away from the cover plate 20, and the second part 32 is insulated from the bottom plate 12. After the first part 31 of the terminal 30 passes through the through hole 121, it is electrically connected to the second pole ear 42 of the pole core 40, and the first part 31 and the second part 32 of the terminal 30 are both insulated from the bottom plate 12. After the terminal 30 is electrically connected to the pole core 40, it will not be electrically connected to the shell body 10, which can prevent the second pole ear 42 of the pole core 40 from being electrically connected to the shell body 10 and the cover plate 20, thereby preventing the battery 200 formed by the battery shell assembly 100 and the pole core 40 from short-circuiting.

[0048] Further, a gap is formed between the peripheral side wall of the first part 31 and the inner side wall of the through hole 121. The gap is an annular gap, and the gap is used to accommodate an insulator so that the first part 31 is insulated from the bottom plate 12. By forming a gap between the peripheral side wall of the first part 31 and the inner side wall of the through hole 121, the gap is used to accommodate an insulator so that the first part 31 is insulated from the bottom plate 12 of the shell body 10, and the second pole ear 42 of the pole core 40 and the bottom plate 12 can be prevented from being electrically connected through the first part 31.

[0049] For example, taking the case where the first part 31 is cylindrical and the through hole 121 is a circular hole, the radial dimension of the first part 31 is smaller than the radial dimension of the through hole 121, that is, the diameter of the first part 31 is smaller than the diameter of the through hole 121, thereby forming an annular gap between the peripheral side wall of the first part 31 and the inner side wall of the through hole 121.

[0050] It should be understood that in some other embodiments, the shape of the first part 31 of the terminal 30 includes but is not limited to a prism, a frustum, a cone, a truncated cone, etc., and the shape of the through hole 121 includes but is not limited to a conical hole, an elliptical hole, a polygonal hole, etc. It is only necessary to ensure that the peripheral side wall of the terminal 30 and the inner side wall of the through hole 121 are spaced to form an annular gap, and the present application does not impose any restrictions on this.

[0051] It is understandable that the radial size of the first portion 31 of the terminal 30 can be set according to the overall size of the battery 200, and the present application does not limit this. Exemplarily, when the battery housing assembly 100 is applied to a button battery, the diameter of the first portion 31 of the terminal 30 ranges from [1, 10] mm.

[0052] Further, the orthographic projection of the second portion 32 on the bottom plate 12 covers the through hole 121, and the outer periphery of the second portion 32 is located between the outer periphery of the opening of the through hole 121 and the outer periphery of the bottom plate 12. Taking the bottom plate 12 as a cylindrical shape, the second portion 32 as a cylindrical shape, and the through hole 121 as a circular hole as an example, the radial dimension of the second portion 32 is greater 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 bottom 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.

[0053] The orthographic projection of the second portion 32 on the bottom plate 12 covers the through hole 121, and the outer periphery of the second portion 32 is located between the outer periphery of the opening of the through hole 121 and the outer periphery of the bottom plate 12, so that the terminal 30 can be abutted against the bottom plate 12, thereby enabling the terminal 30 to be installed at the through hole 121 of the bottom plate 12. The outer periphery of the second portion 32 is located between the outer periphery of the opening of the through hole 121 and the outer periphery of the bottom plate 12, so that the terminal 30 is installed on the bottom plate 12 without exposing the bottom plate 12, so that the appearance of the battery housing assembly 100 is more beautiful.

[0054] In this embodiment, the second portion 32 of the terminal 30 is cylindrical, and the through hole 121 is a circular hole. The diameter of the second portion 32 of the terminal 30 is larger than the diameter of the through hole 121, so that the terminal 30 can be installed at the through hole 121 of the bottom plate 12 and form abutment with the bottom plate 12. The bottom plate 12 is cylindrical, 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: the diameter of the bottom plate 12 ≤ 1, so that the appearance of the battery housing assembly 100 is more beautiful.

[0055] It should be understood that in some other embodiments, the shape of the second part 32 of the terminal 30 includes but is not limited to a prism, a frustum, a cone, a truncated cone, etc., and the shape of the through hole 121 includes but is not limited to a conical hole, an elliptical hole, a polygonal hole, etc. It is only necessary to ensure that the second part 32 of the terminal 30 can be abutted against the base plate 12, and the present application does not impose any restrictions on this.

[0056] In a specific embodiment, the battery housing assembly 100 further includes a connector 50, which is disposed between the second portion 32 and the bottom plate 12. The connector 50 is adhesive and is used to connect the second portion 32 and the bottom plate 12. The connector 50 is also insulating and is used to insulate the second portion 32 from the bottom plate 12.

[0057] More specifically, the connector 50 provided in this embodiment is a hot melt adhesive, and its material includes but is not limited to a thermoplastic or thermosetting material such as polypropylene (PP). The connector 50 is arranged between the second part 32 and the bottom plate 12, so that the second part 32 of the terminal 30 and the bottom plate 12 are insulated, which can prevent the battery housing assembly 100 and the battery 200 formed by the pole core 40 from short-circuiting. Moreover, the connector 50 is also used to connect the second part 32 of the terminal 30 to the bottom plate 12, so that the stability of the terminal 30 installed on the bottom plate 12 is better. At the same time, the connector 50 can also seal the second part 32 of the terminal 30 and the bottom plate 12, so that the battery housing assembly 100 and the battery 200 formed by the battery housing assembly 100 and the pole core have a better overall sealing effect.

[0058] It should be understood that the connector 50 is also in contact with the first part 31 of the terminal 30. When the second part 32 squeezes the connector 50, the connector 50 can be filled into the gap between the peripheral side wall of the first part 31 of the terminal 30 and the inner side wall of the through hole 121 after squeezing, so as to insulate the first part 31 of the terminal 30 and the base plate 12.

[0059] Further, the outer periphery of the connecting member 50 is located between the outer periphery of the second portion 32 and the outer periphery of the bottom plate 12. Taking the connecting member 50 as an annular shape, the second portion 32 as a cylindrical shape, and the bottom plate 12 as a cylindrical shape as an example, the radial dimension of the connecting member 50 is larger than the radial dimension of the second portion 32, and the radial dimension of the connecting member 50 is smaller than the radial dimension of the bottom plate 12. In other words, the outer diameter of the connecting member 50 is larger than the diameter of the second portion 32, and the outer diameter of the connecting member 50 is smaller than the diameter of the bottom plate 12.

[0060] In this embodiment, the outer periphery of the connecting member 50 is located between the outer periphery of the second part 32 and the outer periphery of the bottom plate 12, and the diameter of the connecting member 50 is larger than the diameter of the second part 32, that is, the orthographic projection of the periphery of the second part 32 on the connecting member 50 is completely located on the connecting member 50, thereby, the second part 32 of the terminal 30 close to the bottom plate 12 can be completely flipped by the connecting member 50, which is beneficial to improve the connection stability and insulation stability between the second part 32 of the terminal 30 and the bottom plate 12. In this embodiment, the outer periphery of the connecting member 50 is located between the outer periphery of the second part 32 and the outer periphery of the bottom plate 12, and the diameter of the connecting member 50 is smaller than the diameter of the bottom plate 12, that is, the orthographic projection of the periphery of the connecting member 50 on the bottom plate 12 is completely located on the bottom plate 12, thereby, the connecting member 50 will not expose the periphery of the bottom plate 12, so that the structure of the battery 200 is more beautiful.

[0061] Second embodiment:

[0062] See also Figure 6 , Figure 6 It is a cross-sectional view of a battery provided in the second embodiment of the present application.

[0063] The battery housing assembly 100 in the battery 200 provided in the second embodiment of the present application is substantially the same as the battery housing assembly 100 in the battery 200 provided in the first embodiment of the present application, except that in the battery housing assembly 100 of the battery 200 provided in the second embodiment of the present application, the battery housing assembly 100 further includes an insulating member 60, which is disposed on the side of the bottom plate 12 close to the cover plate 20, and the first portion 31 is penetrated by the insulating member 60 and electrically connected to the second pole ear 42. By providing the insulating member 60, in the battery 200 formed by the battery housing assembly 100 and the pole core 40, the second pole ear 42 of the pole core 40 can be prevented from contacting the bottom plate 12, thereby making the second pole ear 42 of the pole core 40 insulated from the bottom plate 12.

[0064] Third embodiment:

[0065] See also Figure 7 , Figure 7 It is a cross-sectional view of a battery provided in the third embodiment of the present application.

[0066] The battery housing assembly 100 in the battery 200 provided in the third embodiment of the present application is substantially the same as the battery housing assembly 100 in the battery 200 provided in the first embodiment of the present application, except that the terminal 30 of the battery housing assembly 100 in the battery 200 provided in the third embodiment of the present application has a different installation direction.

[0067] In the battery housing assembly 100 of the battery 200 provided in the third embodiment of the present application, the terminal 30 includes a first portion 31 and a second portion 32 which are connected. The first portion 31 is provided with a through hole 121, and the first portion 31 is insulated from the bottom plate 12. The second portion 32 is provided on a side of the bottom plate 12 close to the cover plate 20, and the second portion 32 is electrically connected to the second pole ear 42, and the second portion 32 is insulated from the bottom plate 12.

[0068] The battery housing assembly 100 of the battery 200 provided in this embodiment is provided by integrating the first part 31 and the second part 32 of the terminal 30 on the shell body 10. Since the bottom plate 12 and the side plate 13 are integrally formed, the structural strength of the bottom plate 12 is relatively large. After the bottom plate 12 is installed with the terminal 30, the bottom plate 12 and the shell body 10 assembly are not easily deformed, thereby making the overall structural strength of the battery housing assembly 100 and the battery 200 relatively large, which is conducive to improving the structural stability of the battery housing assembly 100 and the battery 200. At the same time, the structural strength of the battery housing assembly 100 and the battery 200 is relatively large and not easily deformed, which can reduce the stability of the electrical connection of the internal structure of the battery 200 formed by the battery housing assembly 100 and the pole core 40, thereby improving the quality of the battery 200 during use.

[0069] In a specific embodiment, the battery housing assembly 100 of the battery 200 further includes a connector 50, which is disposed between the second portion 32 and the bottom plate 12. The connector 50 is used to connect the second portion 32 and the bottom plate 12, and the connector 50 is also used to insulate the second portion 32 from the bottom plate 12. By disposing the connector 50 between the second portion 32 and the bottom plate 12, so that the second portion 32 of the terminal 30 and the bottom plate 12 are insulated, the battery 200 formed by the battery housing assembly 100 and the pole core 40 can be prevented from short-circuiting. Moreover, the connector 50 is also used to connect the second portion 32 of the terminal 30 and the bottom plate 12, so that the stability of the terminal 30 installed on the bottom plate 12 is better. At the same time, the connector 50 can also seal the second portion 32 of the terminal 30 and the bottom plate 12, so that the battery housing assembly 100 and the battery housing assembly 100 and the pole core 40 form a better sealing effect of the battery 200 as a whole.

[0070] Further, the outer circumference of the connector 50 is located between the outer circumference of the second portion 32 and the outer circumference of the bottom plate 12. Taking the connector 50 as an annular shape, the second portion 32 as a cylindrical shape, and the bottom plate 12 as a cylindrical shape as an example, the radial dimension of the connector 50 is greater than the radial dimension of the second portion 32, and the radial dimension of the connector 50 is smaller than the radial dimension of the bottom 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 smaller than the diameter of the bottom plate 12. On the one hand, the outer diameter of the connector 50 is greater than the diameter of the second portion 32, and the connector 50 is used to completely flip over the side of the second portion 32 of the terminal 30 close to the bottom plate 12, which is conducive to improving the connection stability and insulation stability between the second portion 32 of the terminal 30 and the bottom plate 12. On the other hand, the outer diameter of the connector 50 is smaller than the diameter of the bottom plate 12, and the connector 50 does not expose the periphery of the bottom plate 12, so that the structure of the battery housing assembly 100 and the battery 200 formed by the battery housing assembly 100 and the pole core is more beautiful.

[0071] Furthermore, the orthographic projection of the second portion 32 on the bottom plate 12 covers the through hole 121, and the outer periphery of the second portion 32 is located between the outer periphery of the opening of the through hole 121 and the outer periphery of the bottom plate 12. Taking the bottom plate 12 as a cylindrical shape, the second portion 32 as a cylindrical shape, and the through hole 121 as a circular hole as an example, the radial dimension of the second portion 32 is greater 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 bottom 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.

[0072] The orthographic projection of the second portion 32 on the bottom plate 12 covers the through hole 121, and the outer periphery of the second portion 32 is located between the outer periphery of the opening of the through hole 121 and the outer periphery of the bottom plate 12, so that the terminal 30 can be abutted against the bottom plate 12, thereby enabling the terminal 30 to be installed at the through hole 121 of the bottom plate 12. The outer periphery of the second portion 32 is located between the outer periphery of the opening of the through hole 121 and the outer periphery of the bottom plate 12, so that the terminal 30 is installed on the bottom plate 12 without exposing the bottom plate 12, so that the appearance of the battery housing assembly 100 is more beautiful.

[0073] The above are some implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
