Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0028] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0029] refer to Figures 1 to 7 The embodiment of the present application discloses a battery structure, which can be applied to electronic products, such as mobile phones, tablet computers, smart wearable devices, etc. Of course, it can also be applied to other electrical devices, which are not specifically limited here. Exemplarily, the battery structure can be a battery in a soft buckle packaging method, and of course, it can also be a battery in other forms. The disclosed battery structure includes a housing 100, a battery cell module 200, a circuit board module 300 and an electrical connector 400.

[0030] The housing 100 is a basic installation component of the battery structure, which can provide an installation foundation for components such as the battery cell module 200 and the circuit board module 300. The housing 100 may have a cavity, through which installation space can be provided for other components. In the embodiment of the present application, the battery cell module 200, the circuit board module 300 and the electrical connector 400 are respectively arranged in the cavity of the housing 100, so that the housing 100 can protect the various components arranged in the cavity.

[0031] In addition, the housing 100 may be made of shielding material, which may be a pure metal material, such as copper, nickel, aluminum, etc., which may play a certain role in blocking the external alternating electromagnetic field, so as to weaken the interference of the external alternating electromagnetic field on the battery module 200, the circuit board module 300 and other components, thereby alleviating the voltage disturbance caused by the external electromagnetic field on the battery structure, thereby extending the service life of the battery structure; in addition, the use of shielding material may also improve the overall strength and stability of the housing 100, so that the outer dimensions of the housing 100 are relatively stable and not easily affected by temperature. Of course, the shielding material may also be a metal alloy material, a graphite material, etc., and the specific type is not limited.

[0032] The battery cell module 200 is the core component of the battery structure, which has the functions of storing, charging and discharging electricity; the circuit board module 300 is the control and management part of the battery structure, which can manage the storage, charging and discharging of the battery cell module 200. On the one hand, it can meet the needs under actual working conditions by managing the battery cell module 200. On the other hand, it can also play a certain protective role for the battery cell module 200 to prevent the occurrence of excessive or insufficient current during charging or discharging, or to prevent the battery cell module 200 from being overcharged or over-discharged, thereby improving the service life of the battery structure.

[0033] Considering that the circuit board module 300 can control the battery cell module 200, in the embodiment of the present application, the circuit board module 300 is electrically and mechanically connected to the battery cell module 200. In this way, on the one hand, the circuit board module 300 can be fixedly installed through the battery cell module 200 to ensure the stability of the circuit board module 300, and on the other hand, the battery cell module 200 and the circuit board module 300 can be electrically connected, so as to control and manage the battery cell module 200 through the circuit board module 300. Exemplarily, the circuit board module 300 can be a PCM, of course, it can also be other types, which are not specifically limited here.

[0034] In other embodiments, the circuit board module 300 may also be electrically connected to the battery cell module 200 and mechanically connected to the housing 100 . This approach can also ensure the stability of the circuit board module 300 and enable electrical conduction between the battery cell module 200 and the circuit board module 300 .

[0035] It should be noted here that the above-mentioned mechanical connection forms may include: welding, bonding, riveting, screwing, snapping, plugging, hanging, etc., and of course, other mechanical connection forms may also be used; the above-mentioned electrical connection forms may include: direct welding, wire connection, metal sheet connection, etc., and of course, other electrical connection forms may also be used.

[0036] Considering that the external alternating electromagnetic field will cause disturbances to the components such as the battery module 200 disposed in the housing 100, in order to alleviate this problem, the battery structure in the embodiment of the present application also includes an electrical connector 400, which is connected between the circuit board module 300 and the housing 100, and makes the circuit board module 300 and the housing 100 electrically conductive. Based on this arrangement, when the external alternating electromagnetic field acts on the housing 100 and generates an induced current on the housing 100, the induced current can be transmitted to the circuit board module 300 through the electrical connector 400, and the induced current can be transmitted to the external circuit 500 via the circuit board module 300, thereby effectively preventing the induced current from entering the battery module 200 and affecting the service life of the battery module 200, thereby protecting the battery module 200.

[0037] Compared with some current batteries without shielding function, the battery structure in the embodiment of the present application can effectively reduce the disturbance of the external exchange electromagnetic field to the battery cell module 200, thereby not causing damage to the battery cell module 200, which is beneficial to improving the service life of the battery cell module 200.

[0038] In some embodiments, the circuit board module 300 may be provided with a grounding area, through which the circuit board module 300 can be grounded. When the battery structure is applied to an electronic device, the grounding area can be connected to a grounding circuit of the electronic device, so that the circuit board module 300 can be reliably grounded through the grounding circuit.

[0039] Exemplarily, the grounding area may be a local side surface of the circuit board module 300, or may be a protrusion, a groove, or other structures. Of course, it may also be in other forms, and the specific form is not limited as long as reliable grounding can be achieved.

[0040] In order to realize reliable connection between the circuit board module 300 and the electrical connector 400, a connection structure is provided in the grounding area, one end of the electrical connector 400 is connected to the connection structure, and the other end of the electrical connector 400 is connected to the housing 100. Based on this arrangement, a reliable connection between the electrical connector 400 and the circuit board module 300 can be ensured, and the reliability of electrical conduction between the circuit board module 300 and the housing 100 can be ensured through the electrical connector 400.

[0041] In some embodiments, the connection structure can be a mounting hole or a mounting slot, and accordingly, one end of the electrical connector 400 can be inserted into the mounting hole or the mounting slot to increase the contact area between the electrical connector 400 and the circuit board module 300, thereby achieving efficient transmission of the induced current. Of course, the connection structure can also be in other forms, which are not specifically limited here.

[0042] To prevent the electrical connector 400 from separating from the circuit board module 300, in an embodiment of the present application, the electrical connector 400 and the connection structure can be welded and fixed. In this way, the firmness of the connection between the electrical connector 400 and the connection structure can be ensured, and on this basis, good electrical conductivity between the electrical connector 400 and the connection structure can be ensured.

[0043] When the connection structure is a mounting hole or a mounting slot, one end of the electrical connector 400 can be inserted into the mounting hole or the mounting slot. In this case, welding fixation is used to further improve the firmness of the connection between the electrical connector 400 and the connection structure, thereby improving the reliability of the connection and electrical conduction.

[0044] Similarly, in order to prevent the electrical connector 400 from being separated from the housing 100, in the embodiment of the present application, the electrical connector 400 and the housing 100 can be welded and fixed. In this way, the firmness of the connection between the electrical connector 400 and the housing 100 can be ensured, and on this basis, good electrical conductivity between the electrical connector 400 and the housing 100 can be ensured.

[0045] refer to Figure 3 and Figure 5 In some embodiments, the circuit module may include a flexible board 310, which is fixedly connected to the cell module 200, and the flexible board 310 is electrically connected to the tab 210 of the cell module 200. Based on this configuration, the flexible board 310 can be fixed to ensure the stability of the flexible board 310, and the flexible board 310 can also be used to transmit electric energy between the flexible board 310 and the cell module 200, so as to facilitate the charging or discharging of the cell module 200. The flexible board 310 and the tab 210 can be connected by welding to ensure the reliability of the connection.

[0046] For example, the battery cell module 200 may have a positive electrode tab and a negative electrode tab, and the positive electrode tab and the negative electrode tab are arranged at intervals and are electrically connected to the flexible board 310 respectively, so as to realize power transmission.

[0047] Furthermore, the flexible board 310 may be provided with a connection structure, and the flexible board 310 is electrically connected to the electrical connector 400 through the connection structure. In this way, through the connection between the connection structure and the electrical connector 400, it is possible to ensure a firm connection between the electrical connector 400 and the flexible board 310 without separation, and to achieve stable power transmission between the electrical connector 400 and the flexible board 310.

[0048] For example, the flexible board 310 may be provided with a mounting hole as a connection structure to facilitate the insertion and connection of the electrical connector 400 , thereby improving the reliability of the connection.

[0049] Furthermore, if Figure 6 As shown, the flexible board 310 may include a first side plate 311 and a second side plate 312 that are spaced apart, and a connecting plate 313 that connects the first side plate 311 and the second side plate 312, so that the first side plate 311, the second side plate 312 and the connecting plate 313 together enclose a receiving space 314 to accommodate other components. In addition, when installing the circuit board module 300 and the battery module 200, the second side plate 312 of the flexible board 310 may be connected to the battery module 200, and the first side plate 311 may be arranged away from the battery module 200.

[0050] Exemplarily, the connecting plate 313 can be a U-shaped plate structure, and the two ends of the connecting plate 313 are respectively connected to the end of the first side plate 311 and the end of the second side plate 312, and the connecting plate 313 is located at the same end of the first side plate 311 and the second side plate 312. In this way, under the action of the connecting plate 313, the first side plate 311 and the second side plate 312 can be ensured to be stable and spaced apart.

[0051] Optionally, the first side plate 311 and the second side plate 312 may be connected by an integral connecting plate 313. Of course, the first side plate 311 and the second side plate 312 may also be connected by a plurality of connecting plates 313 of smaller size, and the plurality of connecting plates 313 are arranged at intervals in the respective extending directions of the first side plate 311 and the second side plate 312. Both methods can ensure that the first side plate 311 and the second side plate 312 are stable and arranged at intervals.

[0052] In other embodiments, the flexible board 310 may be an integral board structure, which includes a first side board 311, a second side board 312, and a connecting board 313. In an initial state, the first side board 311, the second side board 312, and the connecting board 313 are located in the same plane, and then the first side board 311 and the second side board 312 are spaced apart by bending the connecting board 313 by 180°, so as to form a flexible board 310 with an accommodating space 314.

[0053] Continue to refer Figure 6 In order to realize the basic functions of the circuit board module 300, the circuit board module 300 may further include a first steel sheet 320, a second steel sheet 330, at least one plastic package 340 and a plurality of tin blocks 350, wherein the first steel sheet 320, at least one plastic package 340 and the second steel sheet 330 are sequentially stacked in the accommodation space 314, wherein the first steel sheet 320 is attached to the first side plate 311, and the second steel sheet 330 is attached to the second side plate 312. Based on this, at least one layer of the plastic package 340 can be clamped by the first steel sheet 320 and the second steel sheet 330, and the first side plate 311 and the second side plate 312 can respectively clamp the first steel sheet 320 and the second steel sheet 330, thereby ensuring the overall stability of the circuit board module 300.

[0054] Further, each plastic package body 340 may be provided with a plurality of through holes 341, a plurality of tin blocks 350 are correspondingly provided in the plurality of through holes 341, and a portion of the plurality of tin blocks 350 are respectively welded to the first steel sheet 320 and the second steel sheet 330, and another portion of the plurality of tin blocks 350 are welded to the tab 210. Based on this arrangement, electrical connection between the plastic package body 340 and the first steel sheet 320 and the second steel sheet 330 may be achieved through a portion of the tin blocks 350, and electrical connection between the tab 210 and the plastic package body 340 may be achieved through another portion of the tin blocks 350, so as to lay a foundation for the transmission of electrical energy by the battery structure.

[0055] It should be noted here that the principle of power transmission between the circuit board module 300 and the battery cell module 200 can refer to the existing technology and will not be elaborated here.

[0056] Considering that the flexible board 310 can be provided with a mounting hole and can be electrically connected to the battery cell module 200 through the electrical connector 400 inserted into the mounting hole, the first side panel 311 can be provided with a mounting hole, that is, a first mounting hole 3111, and the connection between the electrical connector 400 and the first side panel 311 is achieved by inserting the electrical connector 400 into the first mounting hole 3111, which can not only improve the firmness of the connection, but also realize the transmission of electric energy, so as to facilitate the transmission of the induced current, and effectively alleviate the damage to the battery cell module 200 caused by the induced current entering the battery cell module 200.

[0057] The first steel sheet 320 may be provided with a mounting hole, i.e., a second mounting hole 321, and the electrical connector 400 may pass through the second mounting hole 321. Thus, the electrical connector 400 may be avoided by the second mounting hole 321 to prevent the first steel sheet 320 from blocking the electrical connector 400 from passing through. Of course, the firmness of the connection may be improved by the cooperation between the electrical connector 400 and the second mounting hole 321, and the electrical conduction between the electrical connector 400 and the first steel sheet 320 may be achieved, so as to facilitate the transmission of electrical energy.

[0058] The first steel sheet 320 may be provided with a mounting hole, i.e., a second mounting hole 321, and the electrical connector 400 may pass through the second mounting hole 321. Thus, the electrical connector 400 may be avoided by the second mounting hole 321 to prevent the first steel sheet 320 from blocking the electrical connector 400 from passing through. Of course, the firmness of the connection may be improved by the cooperation between the electrical connector 400 and the second mounting hole 321, and the electrical conduction between the electrical connector 400 and the first steel sheet 320 may be achieved, so as to facilitate the transmission of electrical energy.

[0059] The second steel sheet 330 may be provided with a mounting hole, i.e., a third mounting hole 331, and the electrical connector 400 may pass through the third mounting hole 331. Thus, the electrical connector 400 may be avoided by the third mounting hole 331 to prevent the second steel sheet 330 from blocking the electrical connector 400 from passing through. Of course, the firmness of the connection may be improved by the cooperation between the electrical connector 400 and the third mounting hole 331, and the electrical conduction between the electrical connector 400 and the second steel sheet 330 may be achieved, so as to facilitate the transmission of electrical energy.

[0060] Each plastic package body 340 may be provided with a mounting hole, i.e., a fourth mounting hole 342, through which the electrical connector 400 may pass. Thus, the electrical connector 400 may be avoided by the fourth mounting hole 342 to prevent the plastic package body 340 from blocking the electrical connector 400 from passing in. Of course, the firmness of the connection may be further improved by the cooperation between the electrical connector 400 and the fourth mounting hole 342.

[0061] The second side plate 312 may also be provided with a mounting hole, i.e., a sixth mounting hole (not shown in the figure), so that the electrical connector 400 can completely pass through the flexible board 310, and the electrical connector 400 can be connected to the second side plate 312 by inserting the electrical connector 400 into the sixth mounting hole, which can not only improve the firmness of the connection, but also realize the transmission of electric energy, so as to facilitate the transmission of the induced current, and effectively alleviate the damage to the core module caused by the induced current entering the battery cell module 200.

[0062] Based on the above configuration, when the first side panel 311, the first steel sheet 320, the second steel sheet 330, at least one plastic package body 340 and the second side panel 312 are respectively provided with mounting holes, the respective mounting holes are coaxially arranged, and the electrical connector 400 is passed through the respective mounting holes to improve the reliability of the connection between the electrical connector 400 and the circuit board module 300 and ensure good power transmission.

[0063] In addition, the end of the electrical connector 400 protrudes from the first side plate 311 so that the protruding end can be connected to the housing 100 to transmit the induced current.

[0064] In order to realize the charging and discharging process of the battery structure and to play a shielding role, the circuit board module 300 in the embodiment of the present application may also include a control switch 360, a first diode 370, a second diode 380 and a connector 390, such as Figure 7 As shown, the first diode 370 and the control switch 360 are arranged in parallel and are electrically connected to the battery cell module 200 respectively, the second diode 380 is electrically connected to the electrical connector 400, and the circuit board module 300 is electrically connected to the external circuit 500 through the connector 390.

[0065] Based on the above configuration, under the action of the external alternating electromagnetic field, an induced current will be generated on the housing 100. The induced current flows through the electrical connector 400 and flows to the circuit board module 300 via the electrical connector 400. The circuit board module 300 transmits the induced current to the external circuit 500 through the connector 390, thereby effectively preventing the induced current from entering the battery cell module 200 and causing damage to the battery cell module 200.

[0066] Furthermore, in order to prevent the current in the battery cell module 200 from flowing through the circuit board module 300 to the electrical connector 400, and then flowing to the outer shell 100 via the electrical connector 400, in an embodiment of the present application, a second diode 380 may be provided between the connection position between the electrical connector 400 and the circuit board module 300. The second diode 380 may limit the current in the battery cell module 200 from flowing in the reverse direction to the outer shell 100, thereby effectively preventing the outer shell 100 from being charged.

[0067] During the discharge process of the battery structure, the control switch 360 is in an off state. At this time, the current in the battery cell module 200 can flow to the circuit board module 300 and be released through the circuit board module 300 to achieve discharge.

[0068] To prevent the current from flowing back to the battery cell module 200 during discharge, a first diode 370 can be provided between the connection position of the battery cell module 200 and the circuit board module 300. The first diode 370 can limit the current from flowing back into the battery cell module 200, thereby ensuring that the current in the battery cell module 200 can flow out in one direction.

[0069] During the charging process of the battery structure, the control switch 360 is in a closed state. At this time, the first diode 370 is short-circuited, so that the charging current can flow into the battery cell module 200 via the circuit board module 300 and the control switch 360 to charge the battery cell module 200.

[0070] In addition, the control switch 360 and the first diode 370 in the disconnected state can prevent the current generated by the external interactive electromagnetic field from entering the battery cell module 200 when flowing to the circuit board module 300, thereby protecting the battery cell module 200 and extending the service life of the battery cell module 200.

[0071] To ensure the firmness of the connection between the circuit board module 300 and the battery cell module 200, the battery structure may further include a first adhesive member 610, such as Figure 3 As shown, the first adhesive 610 is connected between the circuit board module 300 and the battery cell module 200. Thus, the first adhesive 610 can realize the firmness of the connection between the circuit board module 300 and the battery cell module 200, effectively preventing the two from being separated from each other and affecting the normal use of the battery structure.

[0072] Exemplarily, the first adhesive member 610 may be a double-sided tape, a glue layer, etc. Of course, it may also be in other forms, which are not specifically limited here.

[0073] In some embodiments, the battery structure may also include a first adhesive tape 710 and a second adhesive tape 720, wherein the first adhesive tape 710 is attached to one end of the battery cell module 200 and covers the circuit board module 300. In this way, the first adhesive tape 710 can cover one end of the battery cell module 200 and the circuit board module 300 located at the end, which can protect the first end of the battery cell module 200 and the circuit board module 300 to a certain extent; in addition, it can also help to improve the firmness and reliability of the connection between the circuit board module 300 and the battery cell module 200.

[0074] When the first tape 710 is an insulating tape, it can also separate the tabs 210 of the circuit board module 300 and the cell module 200 from the housing 100, thereby isolating the circuit board module 300 and the tabs 210 from the housing 100 to prevent electrical connection.

[0075] Considering that the electrical connector 400 is connected to the circuit board module 300, in order to prevent the first adhesive tape 710 from blocking the electrical connector 400, the electrical connector 400 can be made to pass through the first adhesive tape 710. Specifically, the first adhesive tape 710 can be provided with a fifth mounting hole 711, through which the electrical connector 400 can pass and be electrically connected to the housing 100, so that the two ends of the electrical connector 400 can be electrically connected to the circuit board module 300 and the housing 100 located on both sides of the first adhesive tape 710, respectively, to ensure that the induced current generated by the housing 100 can be transmitted to the circuit board module 300 via the electrical connector 400, and finally transmitted from the circuit board module 300 to the external circuit 500 without entering the battery cell module 200.

[0076] The second adhesive tape 720 is attached to the other end of the battery cell module 200 away from the circuit board module 300. In this way, the second adhesive tape 720 can cover the end of the battery cell module 200 away from the circuit board module 300, which can protect the other end of the battery cell module 200 to a certain extent.

[0077] When the second adhesive tape 720 is an insulating adhesive tape, it can separate the battery cell module 200 from the housing 100 to prevent the battery cell module 200 from leaking liquid and being electrically connected to the housing 100 .

[0078] Continue to refer Figure 3 In some embodiments, the battery structure may further include an easy-to-tear sticker 810, which is attached to the surface of the battery cell module 200. The easy-to-tear sticker 810 may display some information of the battery cell module 200, such as the capacity, charging power, charging current, charging voltage, precautions, manufacturer, etc. of the battery cell module 200, so that users can better understand the battery structure information.

[0079] To ensure the firmness of the connection between the battery module 200 and the housing 100, the battery structure may further include a second adhesive member 620, such as Figure 3 As shown, the second adhesive 620 is connected between the battery cell module 200 and the housing 100. Thus, the second adhesive 620 can achieve a firm connection between the battery cell module 200 and the housing 100, effectively preventing the two from being separated from each other and affecting the normal use of the battery structure.

[0080] Exemplarily, the second adhesive member 620 may be a double-sided tape, a glue layer, etc. Of course, it may also be in other forms, which are not specifically limited here.
