Referring to fig. 1 and fig. 2 in combination, fig. 1 is a schematic structural diagram of a cylindrical battery 100 according to the present embodiment, and fig. 2 is a schematic structural diagram of a connection structure between an insulating sealing ring 120 and a conductive member 130, and between the insulating sealing ring and a cylindrical housing 110.
The cylindrical battery 100 provided in this embodiment includes a cylindrical housing 110, an insulating sealing ring 120, a conductive member 130, a battery cell 140 and a control board 150, where the cylindrical housing 110 has an open end 111 and a closed end 112 opposite to each other, and the insulating sealing ring 120 is accommodated in the housing and sleeved on an outer sidewall of the conductive member 130; the inner side wall of the opening end 111 is convexly provided with a first annular wall 113, the first annular wall 113 circumferentially extrudes the insulating sealing ring 120 to deform, and a sealed accommodating cavity 160 is formed between the insulating sealing ring 120 and the closed end 112; the electric core 140 is accommodated in the accommodating cavity 160, the electric core 140 is provided with a first electrode 141 and a second electrode 142 with opposite polarities, the first electrode 141 is electrically connected with the conductive piece 130, and the second electrode 142 is electrically connected with the end wall of the closed end 112; the control board 150 is disposed on a side of the insulating sealing ring 120 away from the accommodating cavity 160, and a control circuit of the control board 150 is electrically connected to the conductive member 130 and the cylindrical housing 110 respectively.
It will be appreciated that the control board 150 is provided with a control circuit capable of voltage regulation and grounding, and the control circuit is electrically connected to the conductive member 130, thereby electrically connecting to the first electrode 141. The control circuit is electrically connected to the cylindrical housing 110, thereby making electrical connection to the second electrode 142.
The insulating sealing ring 120 has a certain elastic deformation capability, the inner edge of the insulating sealing ring 120 is sleeved on the conductive member 130, and the outer edge of the insulating sealing ring is circumferentially extruded by the first annular wall 113 protruding from the inner side wall of the cylindrical shell 110, so that the insulating sealing ring is tightly attached to the inner side wall of the cylindrical shell 110 and the outer side wall of the conductive member 130, and the effect of reliably sealing the accommodating cavity 160 is achieved. The electric core 140 is accommodated in the accommodating cavity 160, the control board 150 is positioned at one side of the insulating sealing ring 120 away from the accommodating cavity 160, namely, the insulating sealing ring 120 isolates the electric core 140 from the control board 150, and the conductive piece 130 realizes the electric connection between the control board 150 and the first electrode 141 of the electric core 140. It will be appreciated that in order to avoid shorting, the conductive member 130 is isolated from the cylindrical housing 110 by the insulating seal 120, i.e., the conductive member 130 is not in contact with the cylindrical housing 110.
It can be seen that the tightness of the accommodating cavity 160 where the battery cell 140 is located is not affected by the assembly structure of the control board 150 and the cylindrical housing 110, and even if the assembly structure of the control board 150 and the cylindrical housing 110 is deformed, the electrolyte in the accommodating cavity 160 will not leak. That is, the cylindrical battery 100 provided in this embodiment has the characteristics of better sealing performance, more reliable sealing structure, and stronger explosion-proof pressure release function.
It is understood that the battery cell 140 may be a soft package battery cell 140 or a roll core, and the kind of the battery cell 140 is not specifically limited in this application.
In order to ensure reliable sealing between the inner edge of the insulating sealing ring 120 and the conductive member 130, in this embodiment, a mating ring groove 131 is provided on the sidewall of the conductive member 130, and the inner edge of the insulating sealing ring 120 is circumferentially embedded in the mating ring groove 131.
In practice, a first electrical connection plate 132 is disposed at one end of the conductive member 130 near the accommodating cavity 160, the first electrode 141 is connected with the first electrical connection plate 132, a second electrical connection plate 133 is disposed at one end of the conductive member 130 far away from the accommodating cavity 160, and two sidewalls of the first electrical connection plate 132 and the second electrical connection plate 133 near each other and an outer sidewall of the conductive member 130 enclose a mating ring groove 131.
When the inner edge of the insulating seal ring 120 is fitted into the mating ring groove 131, the inner side wall of the insulating seal ring 120 is bonded to the outer side wall of the conductive member 130, and the side walls of the insulating seal ring 120 on both sides in the thickness direction are bonded to the first and second power receiving plates 132 and 133, respectively. Therefore, the insulating sealing ring 120 is attached to the conductive member 130 in a large area, so that the tightness between the inner edge of the insulating sealing ring 120 and the conductive member 130 is ensured.
In this embodiment, the first ring wall 113 is formed by rolling the outer side wall of the cylindrical shell 110, and the first roller groove 114 is formed on the outer side wall of the opening end 111 at a position corresponding to the first ring wall 113. In practical application, the outer side wall of the open end 111 is rolled circumferentially, so that the corresponding position of the outer side wall is recessed circumferentially and the corresponding inner side wall is raised circumferentially, thereby forming the first roller groove 114 on the outer surface and forming the first ring wall 113 on the inner side wall.
In order to facilitate assembly, in this embodiment, the forming process of the first ring wall 113 is a matching process between the first ring wall 113 and the insulating seal ring 120. That is, after the insulating seal ring 120 is fitted over the conductive member 130 and is fitted into the open end 111 of the cylindrical housing 110, the outer side wall of the open end 111 is subjected to rolling treatment, and the rolling position corresponds to the outer periphery of the insulating seal ring 120. During the rolling process, the raised first ring wall 113 on the inner side wall of the open end 111 simultaneously presses the insulating seal ring 120. After the first annular wall 113 is formed, the matching of the insulating sealing ring 120 and the first annular wall 113 is also completed.
In this embodiment, in order to further ensure the sealing effect, the width of the cross section of the first ring wall 113 is smaller than the thickness of the insulating sealing ring 120, so that the first ring wall 113 is embedded into the insulating sealing ring 120 under the condition that the insulating sealing ring 120 is elastically deformed due to extrusion of the first ring wall 113. In other words, in this state, the end wall of the first annular rib 113 and the side walls on both sides in the width direction are bonded to the outer side wall of the deformed insulating seal ring 120 having a curved shape, so that the bonding area is increased, and a better sealing performance is obtained.
It is understood that the first electrical connection plate 132 is used to electrically connect with the first electrode 141 of the battery cell 140, and the second electrical connection plate 133 is used to electrically connect with the control board 150. In this embodiment, the second power receiving plate 133 has a flat plate structure, and in other embodiments, the structure of the second power receiving plate 133 can be adaptively adjusted to accommodate the structure of the control board 150 for power receiving.
For example, referring to fig. 3, fig. 3 is a schematic diagram showing a connection structure between the insulating seal ring 120 and the conductive member 130 and between the cylindrical housing 110 in another embodiment. The difference between this embodiment and this embodiment is that the structure of the second power receiving plate 133 of the conductive member 130 is different, in this embodiment, a mating recess 1331 is concavely provided on the second power receiving plate 133, and the mating recess 1331 is used for plugging with a protruding structure provided on the control board 150, so as to improve the reliability of the electrical connection between the conductive member 130 and the control board 150.
Referring to fig. 4 again, fig. 4 is a schematic diagram showing a connection structure between the insulating seal 120 and the conductive member 130, and between the insulating seal and the cylindrical housing 110 in another embodiment. In this embodiment, the second electrical connection board 133 is provided with a mating post 1332 in a protruding manner, and the mating post 1332 is used for plugging with a recess structure provided on the control board 150, so as to improve the reliability of the electrical connection between the conductive member 130 and the control board 150.
In this embodiment, the control board 150 includes an insulating base 152, a thimble 153 and a first charge-discharge electrode 151, the thimble 153 and the first charge-discharge electrode 151 are respectively protruded on two opposite sides of the insulating base 152 in the thickness direction, and the thimble 153 is electrically connected with the first charge-discharge electrode 151 through a control circuit, and the thimble 153 is abutted with the second electric connection plate 133, so as to establish an electrical connection between the first charge-discharge electrode 151 and the first electrode 141 of the electric core 140.
A second charge-discharge electrode 118 is provided on the end wall of the closed end 112, the second charge-discharge electrode 118 being electrically connected to the second electrode 142, i.e., the second charge-discharge electrode 118 being electrically connected to the control circuit of the control board 150. It will be appreciated that the control board 150 can ensure that the first charge-discharge electrode 151 and the second charge-discharge electrode 118 are not shorted by the control circuit configuration.
In practical application, the cylindrical battery 100 is electrically connected to an external circuit through the first charging/discharging electrode 151 and the second charging/discharging electrode 118 to realize charging or power supply. It is understood that the specific polarities of the first charge-discharge electrode 151 and the second charge-discharge electrode 118 are determined according to the specific polarities of the first electrode 141 and the second electrode 142 of the battery cell 140. For example, when the first electrode 141 is a positive electrode and the second electrode 142 is a negative electrode, the first charge/discharge electrode 151 is a positive output electrode and the second charge/discharge electrode 118 is a negative output electrode; when the first electrode 141 is a negative electrode and the second electrode 142 is a positive electrode, the first charge/discharge electrode 151 is a negative output electrode, and the second charge/discharge electrode 118 is a positive output electrode.
For the assembly of the control board 150, in this embodiment, a second annular wall 115 is further protruding on the inner side wall of the opening end 111 of the cylindrical shell 110, and the opening end 111 is turned inward to form a stop portion 116, and the second annular wall 115 is further away from the closed end 112 than the first annular wall 113; the side of the second collar 115 facing away from the first collar 113 cooperates with the stop 116 to hold the insulating base 152 of the control plate 150. While the edge of the insulating base 152 is formed with a conductive portion, the conductive portion abuts against the second ring wall 115, and the control circuit on the insulating base 152 is electrically connected with the cylindrical shell 110 through the conductive portion.
In this embodiment, the second annular rib 115 is formed by rolling the outer wall of the cylindrical shell 110 in the same manner as the first annular rib 113, that is, the second roller groove 117 is formed on the outer wall of the opening end 111 at a position corresponding to the second annular rib 115.
In the actual assembly process, after the assembly of the insulating sealing ring 120 is completed, the cylindrical housing 110 may be rolled to form the second ring wall 115, and then the control board 150 is installed into the cylindrical housing 110 from the opening end 111 and is abutted against the second ring wall 115, so that the thimble 153 of the control board 150 is guaranteed to be just abutted against the second electric connection plate 133 of the electric conduction member 130 by presetting the forming position of the second ring wall 115. After that, the opening end 111 is turned inward to form a stop 116, the stop 116 encloses a channel for the first charge-discharge electrode 151 to extend, so that opposite sides of the insulating base 152 in the thickness direction are clamped and fixed by the second ring wall 115 and the stop 116, and the channel enclosed by the stop 116 by the first charge-discharge electrode 151 extends out of the cylindrical shell 110.
It can be appreciated that the circumferential extrusion of the first annular wall 113 against the insulating sealing ring 120 achieves a first-stage sealing of the accommodating cavity 160, and the clamping of the second annular wall 115 and the stop 116 against the insulating base 152 achieves a second-stage sealing of the accommodating cavity 160, so that the sealing performance of the accommodating cavity 160 is more reliable. And, even if the second-stage seal fails due to deformation of the assembly structure of the control board 150 and the cylindrical housing 110, the first-stage seal can ensure that the electrolyte does not leak.
In summary, the cylindrical battery 100 provided in this embodiment has the characteristics of better sealing performance and more stable and reliable sealing structure.
