Examples
Referring to fig. 1 and fig. 2 in combination, fig. 1 is a schematic cross-sectional view of a battery 100 according to the present embodiment, and fig. 2 is an exploded schematic view of the battery 100.
The battery 100 provided in this embodiment includes a casing 110, a control board 120 and a steel casing cell 130, where the casing 110 has an open end 111 and a closed end 112, the control board 120 and the steel casing cell 130 are both contained in the casing 110 and are sequentially arranged from the open end 111 to the closed end 112, a thimble 121 is protruding on one side of the control board 120 near the steel casing cell 130, the thimble 121 is abutted with a pole 131 of the steel casing cell 130, and a steel casing 132 of the steel casing cell 130 is abutted with an inner side wall of the casing 110.
In this embodiment, the casing 110 has a cylindrical shape, and two ends thereof are an open end 111 and a closed end 112, respectively. The control board 120 and the steel casing cell 130 are sequentially arranged from the open end 111 to the closed end 112, the finger control board 120 and the steel casing cell 130 are sequentially arranged on the axis of the casing 110, and the control board 120 is closer to the open end 111, and the steel casing cell 130 is closer to the closed end 112.
The steel-shell battery cell 130 is a conventional element on the market, one end of the steel-shell battery cell close to the control board 120 is provided with a pole 131, the end face of the pole 131 is abutted with the thimble 121 of the control board 120 to establish electrical connection, and the steel shell 132 of the steel-shell battery cell 130 is electrically connected with the shell 110.
In the embodiment, the pole 131 of the steel-can battery cell 130 has positive polarity, and the steel can 132 has negative polarity. It is understood that the control board 120 is internally provided with a control circuit, which plays roles of voltage regulation and grounding. The thimble 121 is connected to the control circuit, and the positive electrode of the steel shell battery cell 130 is connected to the control circuit through the contact between the thimble 121 and the pole 131 of the steel shell battery cell 130. The periphery of the control board 120 is provided with a conductive part, the conductive part is connected to the control circuit, and the conductive part is abutted against the inner side wall of the shell 110, so that the control circuit is electrically connected with the steel shell 132 of the negative electrode of the steel shell cell 130.
In other embodiments, the poles 131 of the steel can cell 130 can also have negative polarity, and the steel can 132 has positive polarity. In this case, the contact between the ejector pin 121 and the pole 131 realizes a negative electrode access control circuit of the steel-case cell 130, and the contact between the conductive portion and the case 110 realizes a positive electrode access control circuit of the steel-case cell 130.
One side of the control board 120 far away from the steel shell battery core 130 is convexly provided with an electrode cap 122, the electrode cap 122 extends out of the opening end 111, and the electrode cap 122 is electrically connected with the thimble 121 through a control circuit, namely, the electrode cap 122 is electrically connected with a pole column 131 of the steel shell battery core 130. It can be seen that, in the battery 100 provided in this embodiment, the electrode cap 122 is a positive electrode, and the housing 110 is a negative electrode. In embodiments in which the post 131 of the steel can cell 130 is negative and the steel can 132 is positive, the electrode cap 122 of the battery 100 is negative and the housing 110 is positive.
In the battery 100 provided in this embodiment, during assembly, the steel casing cell 130 and the control board 120 are only required to be sequentially assembled into the casing 110, and the terminal post 131 of the steel casing cell 130 is ensured to face the open end 111 during the assembly process, and the ejector pin 121 of the control board 120 is ensured to face the closed end 112.
After the steel shell electric core 130 is put into the shell, the steel shell 132 of the steel shell electric core is abutted with the inner side wall of the shell 110 to establish electric connection, after the control board 120 is put into the shell, the thimble 121 of the steel shell electric core is abutted with the pole column 131 of the steel shell electric core 130 to establish electric connection between a control circuit and the anode of the steel shell electric core 130, and the conductive part on the control board 120 is abutted with the side wall of the shell 110 to establish electric connection between the control circuit and the cathode of the steel shell electric core 130.
In this embodiment, a limiting ring wall 113 is convexly arranged on the inner side wall of the housing 110, the opening end 111 is turned inwards to form a stop ring wall 114, the stop ring wall 114 and the limiting ring wall 113 are arranged at intervals and jointly clamp the control plate 120, and the ejector pin 121 passes over the limiting ring wall 113 and is abutted against the pole 131 of the steel-shell battery cell 130.
The limiting ring wall 113 is located between the control board 120 and the steel shell cell 130, the limiting ring wall 113 is obtained by rolling the outer side wall of the shell 110, that is, an annular roller groove 115 is formed on the outer side wall of the shell 110 at a position corresponding to the limiting ring wall 113. In practical application, in order to facilitate the steel-shell cell 130 to be put into the shell, the operation of rolling the limiting ring wall 113 is performed after the steel-shell cell 130 is put into the shell, so as to avoid the blocking of the limiting ring wall 113 on the steel-shell cell 130.
After the steel shell cell 130 is put into the shell and the limit ring wall 113 is formed by rolling, the control plate 120 is put into the shell 110 from the opening end 111 until the control plate 120 is in circumferential contact with the limit ring wall 113, and the thimble 121 of the control plate is ensured to be just in contact with the pole 131 of the steel shell cell 130 by the preset size. In this state, the opening end 111 is turned inward to form the stop annular wall 114, and the stop annular wall 114 abuts against one side of the control plate 120, which is away from the limiting annular wall 113, i.e. the stop annular wall 114 and the limiting annular wall 113 jointly realize clamping and fixing of the control plate 120.
It will be appreciated that during the process of folding open end 111 to form stop collar 114, it is desirable to ensure that the inner edge of stop collar 114 does not contact electrode cap 122, avoiding a short circuit between the positive and negative electrodes. In other words, in the present embodiment, a gap exists between the electrode cap 122 and the stopper annular wall 114.
In order to further reduce the assembly difficulty and improve the assembly accuracy, in this embodiment, the control board 120 and the steel shell cell 130 are coaxially arranged with the housing 110, the control board 120 is circumferentially abutted against the inner side wall of the housing 110, the outer side wall of the steel shell cell 130 is circumferentially abutted against the inner side wall of the housing 110, the thimble 121 is arranged on the axis of the housing 110, and the pole 131 of the steel shell cell 130 is arranged on the axis thereof.
Therefore, because the dimensions are set in advance, when the steel shell battery cell 130 and the control board 120 are sequentially assembled into the shell 110, the ejector pins 121 can be ensured to be automatically aligned and abutted against the pole posts 131 of the steel shell battery cell 130, secondary alignment is avoided, the assembly difficulty is greatly reduced, and the assembly accuracy is improved.
In summary, in the battery 100 provided in this embodiment, the steel shell battery cell 130 is used, only one thimble 121 is disposed on the control board 120, the positive electrode of the steel shell battery cell 130 is electrically connected with the control circuit by abutting the pole 131 of the steel shell battery cell 130 with the thimble 121, and the negative electrode of the steel shell battery cell 130 is electrically connected with the control circuit by abutting the steel shell 132 of the steel shell battery cell 130 with the casing 110.
