[0057] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present application. However, it is obvious to those skilled in the art that the present application embodiments can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present application embodiments, some technical features well known in the art are not described.

[0058] Herein, ordinal numbers such as “first” and “second” cited in the present application are merely identifications and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term “first component” itself does not imply the existence of the “second component”, and the term “second component” itself does not imply the existence of the “first component”.

[0059] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0060] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0061] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0062] Figures 1 to 4 A battery and its housing assembly according to the present application are shown, and the housing assembly of the battery includes a housing 100, an electrode end cap 130, and a mounting member 120. The electrode end cap 130 is used to be electrically connected to the core 110 of the battery to serve as an electrode of the battery. The mounting member 120 is used to snap onto the housing 100 and at least partially fix the electrode end cap 130 between the mounting member 120 and the housing 100.

[0063] According to the battery housing assembly of the present application, the electrode end cap 130 serves as the battery electrode, and is fixedly matched with the battery housing 100 through the mounting member 120, with fewer parts and a simple structure, which reduces the difficulty of processing and assembling the battery, and the size of the electrode end cap 130 is less restricted, which can reduce the internal resistance of the battery. In addition, the electrode end cap 130 is at least partially located between the mounting member 120 and the housing 100, so that the mounting member 120 has a certain protective effect on the electrode end cap 130.

[0064] like Figure 1As shown, the shell assembly of the battery according to the present application is explained below taking a cylindrical battery as an example. However, this does not mean that the shell assembly of the battery according to the present application is only applicable to cylindrical batteries. Rectangular batteries, cubic batteries and irregularly shaped batteries should all be within the scope of application of the shell assembly of the battery according to the present application.

[0065] The housing 100 may be cylindrical, and accordingly, the mounting member 120 may be annular in shape as a whole.

[0066] Further, see Figures 1 to 4 , the electrode end cap 130 does not protrude from the mounting member 120 along the axial direction D1 of the battery, and it is not easy for foreign objects to contact the electrode end cap 130, so that the mounting member 120 has a good protective effect on the electrode end cap 130. In detail, the electrode end cap 130 is provided with a connecting boss 131 for electrically connecting the battery, and the connecting boss 131 is located in the mounting member 120, or the connecting boss 131 can also be flush with the top surface of the mounting member 120. The connecting boss 131 of the electrode end cap 130 serves as an electrode column of the battery, and is located in the mounting member 120 or flush with the mounting member 120, so that the connecting boss 131 is not exposed outside the battery, and has a good protective effect on the connecting boss 131. The electrode end cap 130 is fixed relative to the battery housing 100 by snapping the mounting member 120 with the battery housing 100, so that the electrode end cap 130 is protected by the mounting member 120, and the connecting boss 131 (i.e., the pole of the existing battery) for electrically connecting the battery does not protrude from the mounting member 120 along the axial direction D1, thereby further providing a better protection effect for the connecting boss 131.

[0067] As an alternative, the electrode end cap 130 may also be configured to protrude from the mounting member 120 along the axial direction D1 of the battery, which can prevent external connectors from being recessed into the mounting member 120 and facilitate connection. At the same time, the electrode end cap 130, except for the portion protruding from the mounting member 120, still has the protection of the mounting member 120.

[0068] Reference Figure 4 The mounting member 120 is provided with a first edge 121 on the periphery thereof, and the first edge 121 is arranged around the electrode end cap 130. The first edge 121 is used to connect the housing 100 and the electrode end cap 130. The mounting member 120 connects the housing 100 and the electrode end cap 130 through the first edge 121 arranged on the periphery thereof, so that the periphery of the electrode end cap 130 is protected and the connection is more stable.

[0069] Further, the electrode end cap 130 is provided with a second edge 132 on the circumference. The first edge 121 is formed with a mounting groove 122. The first edge 121 is provided with an opening 125 on the side facing the mounting member 120, and the first edge 121 further includes a first connecting portion 126, which is located at the upper end of the opening 125. The second edge 132 is sleeved to the opening 125, and the second edge 132 is connected and fixed to the first edge 121 in the mounting groove 122. The electrode end cap 130 is fixed to the mounting groove 122 of the first edge 121 through the second edge 132 provided on the circumference, so that the second edge 132 used as the connection position of the electrode end cap 130 can be protected by the first edge 121, so that the connection between the electrode end cap 130 and the mounting member 120 is more stable.

[0070] Reference Figure 4 The first edge 121 includes a first portion 127, and the first connecting portion 126 is arranged at an angle with the first portion 127 (for example Figure 4 The first connecting portion 126 and the first portion 127 are at 90 degrees. The second edge 132 includes a second connecting portion 134 and a fitting portion 135. The second connecting portion 134 is located on the inner side of the first edge 121 and abuts against the first connecting portion 126. The fitting portion 135 is connected to the second connecting portion 134 at an angle (for example Figure 4 The middle engaging portion 135 is at 90 degrees to the second connecting portion 134. The engaging portion 135 is disposed in the mounting groove 122 and abuts against the first portion 127. The electrode end cap 130 is fixed to the mounting member 120 by the second edge 132 abutting against the first edge 121.

[0071] An arc surface 133 is formed on the outer side of the connection between the second connection part 134 and the fitting part 135, and a chamfer 160 is provided on the inner side of the first connection part near one end of the opening. The chamfer 160 and the arc surface 133 are used to guide the fitting part 135 into the installation groove 122, which is beneficial to prevent the fitting part 135 from being damaged by contact with the opening 125, and can also limit the movement of the electrode end cap 130 in the radial direction D2. The arc surface 133 can be formed when the second edge 132 is stamped, or when the electrode end cap 130 is cast, or it can also be formed by machining.

[0072] Reference Figure 4 The housing assembly of the battery according to the present application further includes a seal 140, which is fitted between the mounting member 120 and the electrode end cap 130, and is mainly used for battery sealing, while adding additional insulation between the electrode end cap 130 and the housing 100, and can also play a shock-absorbing role, which is conducive to further protecting the electrode end cap 130. The seal 140 can be made of insulating rubber material for easy production.

[0073] Furthermore, the housing 100 is provided with a bending opening 101 at the end facing the mounting member 120, and the first edge 121 includes a second portion 128 connected at an angle to the first portion 127. The inner wall of the second portion 128 at one end away from the first portion 127 is provided with a third connecting portion 129, which is connected and fixed to the bending opening 101.

[0074] The third connection portion 129 forms a first protruding portion 123 . The bending opening 101 is provided with a second recessed portion 102 . The first protruding portion 123 cooperates with the second recessed portion 102 to connect and fix the housing 100 and the first edge 121 .

[0075] Furthermore, the third connection portion 129 may also be formed with a first recessed portion 124 , and correspondingly, the bending opening 101 is provided with a second raised portion 103 , and the first recessed portion 124 cooperates with the second raised portion 103 to connect and fix the housing 100 and the first edge 121 .

[0076] Preferably, the third connection portion 129 is formed with a first protrusion 123 and a first recess 124 , and correspondingly, the bending opening 101 is provided with a second protrusion 103 and a second recess 102 , so that the connection between the bending opening 101 and the first edge 121 is more stable.

[0077] In detail, the bending mouth 101 is rolled to form a second recessed portion 102 and a second raised portion 103, the second recessed portion 102 cooperates with the first raised portion 123, and the second raised portion 103 cooperates with the first recessed portion 124, so that the first edge 121 is engaged with the bending mouth 101, so that the mounting member 120 is buckled to the housing 100. The second recessed portion 102 and the second raised portion 103 can be optionally formed by rolling the bending mouth 101, and the structural strength is high.

[0078] The first protrusion 123 and the first recess 124 are correspondingly arranged, and the first protrusion 123 and the first recess 124 may be arranged at intervals along the circumferential direction D3 of the mounting member 120. The second recess 102 and the second protrusion 103 may be extended along the circumferential direction D3 of the bending opening 101, which is easy to engage and process.

[0079] Reference Figure 4The seal 140 is provided with a pressing groove 141, and the seal 140 is sleeved to the bending opening 101 through the pressing groove 141. Therefore, when the mounting member 120 is buckled onto the housing 100, the seal 140 is filled into the mounting groove 122 due to the engagement between the bending opening 101 and the first edge 121, thereby further strengthening the seal between the first edge 121 and the bending opening 101. The second protrusion 103 and the second recess 102 of the bending opening 101 are both penetrated into the pressing groove 141, and the inner wall of the pressing groove 141 is attached to the bending opening 101, which can strengthen the connection strength between the seal 140 and the bending opening 101 along the axial direction D1, and prevent the seal 140 from being separated from the housing 100.

[0080] As an alternative, only part of the second protrusion 103 of the bending mouth 101 may be inserted into the pressing groove 141, or only part of the second recessed portion 102 of the bending mouth 101 may be inserted into the pressing groove 141, both of which can strengthen the connection strength between the seal 140 and the bending mouth 101 along the axial direction D1 to prevent the seal 140 from detaching from the shell 100.

[0081] In addition, due to the setting of the seal 140, the second connection portion 134 of the second edge 132 is separated from the bending opening 101 by the seal 140, and the electrode end cap 130 is separated from the core 110 along the axial direction D1, so that the electrode end cap 130 is insulated from the shell 100 to prevent the shell 100 from being charged.

[0082] In addition, the mounting member 120 should be made of insulating material, such as insulating plastic, to prevent the housing 100 from being charged.

[0083] Reference Figure 4 As can be seen from the above, the cross-section of the bending opening 101 is wavy. In addition, as an alternative, the cross-section of the bending opening 101 can also be L-shaped or T-shaped, etc. It is only necessary to snap the bending opening 101 into the installation groove 122 of the first edge 121 so that the shell 100 and the installation component 120 are fixed together.

[0084] Reference Figure 2 and Figure 3 The housing assembly of the battery according to the present application further includes a current collecting plate 150, which is connected to the electrode end cap 130 and is used to connect to the core 110 of the battery. Figure 8 and Fig. 9As shown, the current collecting plate 150 includes a plate body 151 and a conductive telescopic member 152, and the plate body 151 is connected to the electrode end cap 130. The first end of the conductive telescopic member 152 is connected to the plate body 151, and the second end of the conductive telescopic member 152 is used to connect to the battery core 110. The arrangement of the conductive telescopic member 152 facilitates welding between the current collecting plate 150 and the battery core 110, and also facilitates the installation of the current collecting plate 150 with the electrode end cap 130 and the collection of the battery shell 100 after welding.

[0085] Furthermore, the conductive telescopic member 152 includes at least two conductive sheets 153, and the at least two conductive sheets 153 are connected in sequence, and adjacent conductive sheets 153 are connected in a bendable manner. Figure 8 and Fig. 9 As shown, the conductive telescopic member 152 includes two conductive sheets 153, one conductive sheet 153 is connected to the disc 151, and the other conductive sheet 153 is connected to the core 110 of the battery. Through the connection of the two conductive sheets 153, the disc 151 and the electrode end cap 130 can be received into the battery housing 100. In addition, the arrangement of the collecting disc 150 can also buffer the core 110 and the electrode end cap 130 of the battery along the axial direction D1, preventing the core 110 from shaking along the axial direction D1 and causing wear between the electrode end cap 130.

[0086] In addition, the disk body 151 can be optionally in a petal shape, and the edge of the disk body 151 protrudes from the disk body 151 along the axial direction D1 and is connected to the electrode end cover 130, while the center of the disk body 151 is in a circular ring shape and is connected to the conductive sheet 153. The setting of the disk body 151 further enhances the elasticity between the electrode end cover 130 and the core body 110 along the axial direction D1, thereby reducing the vibration of the core body 110 in the shell 100 when the battery is subjected to external force.

[0087] The present application also provides a battery, comprising a shell assembly and a core 110 of the battery described above. The core 110 is disposed inside the shell 100 and is electrically connected to the electrode end cap 130. The battery according to the present application has a simple structure at the end, which is easy to process and assemble. Moreover, since the end of the battery is less restricted in size as the electrode end cap 130 of the electrode, it is directly connected to the current collecting plate 150, which can reduce the internal resistance of the battery.

[0088] Reference Figures 5 to 9 The present application also provides a method for assembling the above-mentioned battery, comprising:

[0089] S1, inserting the core 110 into the housing 100;

[0090] S2, rolling to form bending openings 101 at both ends of the housing 100;

[0095] S7 , assembling the mounting component 120 , and fastening and fixing the mounting component 120 to the housing 100 .

[0096] According to the battery assembly method of the present application, the assembly difficulty is low, the operation is easy, it is suitable for industrial production, and the assembly efficiency is high.

[0097] Optionally, in S7 , after the mounting component 120 is buckled into the shell 100 , the outer side of the first edge 121 may be heated and pressurized so that the mounting component 120 and the bending opening 101 are fixed by heat melting, thereby improving the connection strength between the mounting component 120 and the shell 100 .

[0098] Optionally, the electrode end cap 130 can also be provided as an insert in the injection mold, so as to be integrally formed with the mounting member 120, and the connection is firm, and the steps of installing the electrode end cap 130 and assembling the mounting member 120 are combined to simplify the assembly method. The electrode end cap 130 and the housing 100 are preferably made of aluminum, and can also be selected from cold-rolled carbon steel or stainless steel.
