[0001] The present application belongs to the field of battery technology, and specifically relates to a protection board assembly, a battery and an electronic device. Background Art

[0002] With the development of electronic communication technology and users' demand for electronic equipment, electronic equipment has realized more and more functions, and the functions are becoming more and more perfect, which makes the power consumption of electronic equipment higher and higher and the heat generation more and more serious.

[0003] At present, with the rapid development of the capacity and charging speed of electronic devices, the structural design size of the protection board assembly has been continuously compressed, and the available space for heat dissipation design has been reduced, making it difficult to meet the thermal management requirements of the protection board assembly. The specific reason is that the pursuit of charging speed by electronic devices has led to an increase in charging current and power, and the high-power charging process requires more protection components and more sophisticated chips, which will further aggravate the generation of heat and occupy the space of the protection board assembly.

[0004] However, due to the concentrated layout of power devices, the existing protection board components have poor heat dissipation effect and cannot quickly dissipate heat and cool down, resulting in heating in the concentrated area of ​​power devices, seriously affecting the normal use of electronic equipment.

Among them, the first protection module includes a heat conductor, and the second protection module includes a power device, and the heat conductor and the power device are both arranged in the storage space. In practical applications, since the power device and the heat conductor are alternately arranged along the first direction, or the heat conductor and the power device are relatively arranged along the second direction, and the power device will generate a large amount of heat in a concentrated manner during normal operation, based on the principle of heat exchange, the heat generated by the power device can be transferred to the heat conductor by heat conduction or heat radiation. It can be understood that the distance between the alternately arranged or relatively arranged heat conductor and the power device is closer, which can improve the efficiency of heat exchange. Furthermore, the setting of the heat conductor is used to absorb the heat generated by the power device, which has the beneficial effect of reducing the degree of heat generation in the concentrated area of ​​the power device and improving the service life of the power device.

Furthermore, the electronic device having the above-mentioned battery can have better heat dissipation performance by providing a heat conductive member and a power device sequentially arranged along a first direction in the protection board assembly, or providing a heat conductive member and a power device relatively arranged along a second direction in the protection board assembly, thereby avoiding overheating of the electronic device, and being able to more effectively reduce the system operating temperature in the electronic device and improve the heat dissipation effect.

[0022] In the embodiment of the present application, the first protection module 10 and the second protection module 20 are enclosed to form a storage space, and the storage space has at least one opening, and the opening is set to dissipate the heat in the storage space from the storage space. Among them, the first protection module 10 includes a heat conductor 11, and the second protection module 20 includes a power device 21, and the heat conductor 11 and the power device 21 are both arranged in the storage space. In practical applications, since the power device 21 and the heat conductor 11 are alternately arranged along the first direction X, or the heat conductor 11 and the power device 21 are relatively arranged along the second direction Z, and the power device 21 will generate a large amount of heat in a concentrated manner during normal operation, based on the principle of heat exchange, the heat generated by the power device 21 can be transferred to the heat conductor 11 in the form of heat conduction or heat radiation. It can be understood that the distance between the alternately arranged or relatively arranged heat conductor 11 and the power device 21 is relatively close, which can improve the efficiency of heat exchange. Further, the setting of the heat conductor 11 is used to absorb the heat generated by the power device 21, which has the beneficial effect of reducing the degree of heat generation in the concentrated area of ​​the power device 21 and improving the service life of the power device 21.

[0023] Furthermore, since the heat conducting member 11 and the power device 21 are sequentially arranged along the first direction X, the heat dissipation capacity of the protection plate assembly is improved without affecting the thickness of the protection plate assembly.

[0024] It should be noted that the power device 21 may be a resistor or other device that generates heat during normal operation, and this embodiment does not impose any limitation on this.

[0025] It should also be noted that the material of the heat conductor 11 can be graphene, and the heat conductor 11 can also be a composite member composed of a graphene film and a metal material, which can absorb the heat generated by the power device 21. This embodiment does not impose any limitation on this.

[0026] It should also be noted that the accommodating space may also have two openings, for example, a first opening and a second opening arranged opposite to each other along a first direction, and heat can be dissipated from the first opening and the second opening, which has the beneficial effect of further improving the heat dissipation capacity of the protective plate assembly.

[0027] It should also be noted that the power device 21 can be any device that generates heat during operation, such as a power amplifier, a resistor, and other devices. This embodiment does not impose any limitation on the specific power device 21.

[0028] Optionally, in the embodiment of the present application, the heat conducting member 11 is in contact with the power device 21 .

[0029] In the embodiment of the present application, the heat conductor 11 and the power device 21 are in contact along the first direction X, or the heat conductor 11 and the power device 21 are in contact along the second direction Z. Based on the heat exchange principle, the heat conductor 11 and the power device 21 in contact with each other can transfer heat by heat conduction. Specifically, the heat generated by the power device 21 is transferred to the heat conductor 11 by heat conduction. The heat conductor 11 is configured to absorb the heat generated by the power device 21, which has the beneficial effect of reducing the heat generation of the concentrated area of ​​the power device 21 and increasing the service life of the power device 21.

[0030] Optionally, in the embodiment of the present application, there is a preset interval between the heat conducting member 11 and the power device 21 .

[0031] In the embodiment of the present application, the heat conductor 11 and the power device 21 may have a preset gap along the first direction X, or the heat conductor 11 and the power device 21 may have a preset gap along the second direction Z. Based on the principle of heat exchange, the heat conductor 11 and the power device 21 in contact with each other may transfer heat by thermal radiation. Specifically, the heat generated by the power device 21 is transferred to the heat conductor 11 by thermal radiation. The heat conductor 11 is configured to absorb the heat generated by the power device 21, which has the beneficial effect of reducing the degree of heat generation in the concentrated area of ​​the power device 21 and increasing the service life of the power device 21.

[0032] Optionally, in an embodiment of the present application, the first protection module 10 also includes a heat sink 12, which is disposed in the accommodating space, and the second protection module 20 includes a control device 22, which is disposed in the accommodating space; the heat sink 12 and the control device 22 are relatively disposed along the second direction Z, and the heat sink 12 includes two sides relatively disposed along the first direction X, one side of the heat sink 12 is close to the heat conductor 11, and the other side of the heat sink 12 is close to the opening.

[0033] In the embodiment of the present application, the heat sink 12 is provided to dissipate the heat in the accommodation space along the opening. Specifically, the heat sink 12 is close to the heat conductor 11, and the heat sink 12 includes two sides arranged relatively along the first direction X, one side of the heat sink 12 is close to the heat conductor 11, and the other side of the heat sink 12 is close to the opening. The heat sink 12 close to the heat conductor 11 has the function of dissipating the heat of the heat conductor 11, and the two sides of the heat sink 12 are respectively close to the heat conductor 11 and the opening, which has the function of shortening the heat transfer path, thereby increasing the heat dissipation rate and shortening the retention time of the heat in the accommodation space. Compared with the protective plate assembly only provided with the heat conductor 11, the provision of the heat sink 12 further improves the ability to dissipate heat from the accommodation space, has the beneficial effect of reducing the degree of heat generation in the concentrated area of ​​the power device 21, and improving the service life of the power device 21.

[0034] Furthermore, since the protection plate assembly has a accommodating space, it can be understood that the accommodating space has a certain interval along the second direction Z, and the heat sink 12 and the control device 22 are relatively arranged along the second direction Z. This improves the heat dissipation capacity of the protection plate assembly without increasing the thickness of the protection plate assembly, and also has the beneficial effect of improving the compactness of the device layout in the protection plate assembly.

[0035] It should be noted that the heat sink 12 may be made of graphene, or may be a composite of a graphene film and a metal material, which can absorb the heat generated by the power device 21 , and this embodiment does not impose any limitation on this.

[0037] In the embodiment of the present application, the power device 21 includes a plurality of power sub-components 211. In practical applications, the power sub-components 211 may be the same or different, and may be a resistor that generates heat during normal operation, or may be other devices that generate heat during normal operation, and this embodiment does not impose any limitation on this. The heat conductor 11 includes a plurality of heat-conducting sub-components 111, and the plurality of power sub-components 211 and the plurality of heat-conducting sub-components 111 are alternately arranged along the first direction X, or the plurality of heat-conducting sub-components 111 and the plurality of power sub-components 211 are arranged one by one in a relative manner along the second direction Z. It can be understood that the power sub-components 211 and the heat-conducting sub-components 111 alternately arranged along the first direction X, or the heat-conducting sub-components 111 and the power sub-components 211 arranged one by one in a relative manner along the second direction Z, can conduct most of the heat generated by each power device 21 to the closest heat-conducting sub-component 111, so that the heat generated by each power sub-component 211 can be conducted to the heat-conducting sub-component 111. In the above arrangement, by reducing the heat of each power sub-component 211, the concentrated heat generation of the power device 21 is reduced, which has the beneficial effect of increasing the service life of the power sub-component 211 and improving the heat dissipation capacity of the protection board assembly.

[0038] Optionally, in the embodiment of the present application, the heat conduction subcomponent 111 and the power subcomponent 211 are in contact.

[0039] In the embodiment of the present application, the heat conducting subcomponent 111 and the power subcomponent 211 are in contact along the first direction X, or the heat conducting subcomponent 111 and the power subcomponent 211 are in contact along the second direction Z. Based on the heat exchange principle, the heat conducting subcomponent 111 and the power subcomponent 211 in contact with each other can transfer heat by heat conduction. Specifically, the heat generated by the power subcomponent 211 is transferred to the heat conducting subcomponent 111 by heat conduction. The heat conducting subcomponent 111 is configured to absorb the heat generated by the power subcomponent 211, which has the beneficial effect of reducing the heat generation of the concentrated area of ​​the power subcomponent 211 and increasing the service life of the power subcomponent 211.

[0040] Optionally, in the embodiment of the present application, there is a preset interval between the heat conduction subcomponent 111 and the power subcomponent 211 .

[0041] In the embodiment of the present application, the heat conducting subcomponent 111 and the power subcomponent 211 may have a preset gap along the first direction X, or the heat conducting subcomponent 111 and the power subcomponent 211 may have a preset gap along the second direction Z. Based on the heat exchange principle, the heat conducting subcomponent 111 and the power subcomponent 211 that are in contact with each other may transfer heat by means of thermal radiation. Specifically, the heat generated by the power subcomponent 211 is transferred to the heat conducting subcomponent 111 by means of thermal radiation. The heat conducting subcomponent 111 is configured to absorb the heat generated by the power subcomponent 211, which has the beneficial effect of reducing the degree of heat generation in the concentrated area of ​​the power subcomponent 211 and increasing the service life of the power subcomponent 211.

[0042] Optionally, in the embodiment of the present application, the orthographic projection of the heat dissipation element 12 along the second direction Z covers at least a portion of the orthographic projection of the control device 22 along the second direction Z.

[0043] In the embodiment of the present application, the heat sink 12 is configured to dissipate the heat in the accommodation space from the first opening or the second opening to the accommodation space, so as to reduce the degree of heat concentration of the power device 21 in the protection plate assembly. Specifically, the orthographic projection of the heat sink 12 along the second direction Z covers at least part of the orthographic projection of the control device 22 along the second direction Z. It can be understood that the above configuration can make the heat near the control device 22 absorbed by the heat sink 12 and then dissipated through the first opening or the second opening, which has the beneficial effect of reducing the heat generated by the power device 21 from affecting the working performance of the control device 22.

[0044] Optionally, in the embodiment of the present application, at least one heat conducting subcomponent 111 is sandwiched between the power device 21 and the control device 22 .

[0045] In the embodiment of the present application, at least one heat-conducting sub-component 111 is disposed between the power device 21 and the control device 22, so that heat can be quickly transferred between the heat-conducting sub-component 111 and the heat sink 12. Specifically, the heat sink 12 and the control device 22 are arranged relative to each other along the second direction Z, and the heat is transferred from the heat-conducting sub-component 111 to the heat sink 12 through a shorter path, and then dissipated from the first opening or the second opening through the heat sink 12, which can effectively reduce the time that the heat is retained in the accommodation space, thereby having the beneficial effect of reducing the degree of heat generation of the protection plate assembly.
