Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0032] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0033] In this specification, for convenience, terms indicating orientation or positional relationships such as "middle", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are used to describe the positional relationships of the components with reference to the accompanying drawings. This is only for the convenience of describing this specification and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present disclosure. The positional relationships of the components are appropriately changed according to the directions of the described components. Therefore, it is not limited to the terms described in this specification and can be appropriately replaced according to the situation.

[0034] In this specification, unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection, an indirect connection through an intermediate member, or a communication inside two components. For those of ordinary skill in the art, the meanings of the above terms in this disclosure can be understood according to the circumstances.

[0035] Due to its simple operation and low usage threshold, drones have been favored by more and more users in recent years. During the flight of a drone, due to relatively high power consumption, high-rate discharge of the battery is often required during operation to deliver a larger current. Therefore, a battery pack connected by multiple cell components needs to be used for power supply. However, for the battery pack formed by stacking multiple cell components, a large amount of heat will be generated during the flight of the drone, and the heat inside the cell components cannot be conducted out in time, resulting in too high a battery temperature and affecting battery performance.

[0036] Currently, the commonly adopted solutions for battery modules in related technologies are simple stacking of cell components or adding heat-conducting materials such as heat-conducting silicone and aluminum plates between cell components to conduct the heat inside the stacked cell components to the outer shell for heat dissipation. However, the heat dissipation efficiency in related technologies is slow and the effect is poor, and the problem of too high a temperature of the battery module during high-rate discharge cannot be effectively solved, which makes the drone prone to overheat and forced landing during flight and also affects the service life of the drone battery.

[0037] Please refer to Figures 1 to 3 , Figure 1 which is a schematic structure diagram of a battery module provided by an embodiment of the present application. Figure 1 , Figure 2 is Figure 1 an enlarged schematic structural diagram of area A in Figure 3 and which is a schematic structure diagram of a support member provided by an embodiment of the present application. The present application provides a battery module 100 to solve the technical problem that the heat dissipation effect of the battery module in related technologies is not ideal enough and the problem of too high a temperature during high-rate discharge cannot be effectively solved.

[0038] The battery module 100 includes a plurality of battery cell components 10 and a plurality of support members 20. The plurality of battery cell components 10 are stacked in sequence along their thickness direction. The plurality of support members 20 are stacked in sequence along their thickness direction, and each support member 20 is disposed between two adjacent battery cell components 10; the support member 20 includes a plurality of first through holes 201 penetrating the support member 20 along a first direction, and the support member 20 further includes a plurality of second through holes 202 penetrating the support member 20 along a second direction, and the first through holes 201 communicate with the second through holes 202; wherein, both the first direction and the second direction are perpendicular to the thickness direction, and there is an included angle between the first direction and the second direction.

[0039] The battery module 100 provided in this embodiment is mainly used to supply power to various electronic devices. The battery module 100 is electrically connected to the internal circuit components of the electronic device, so that the electronic device can realize relevant electronic functions.

[0040] The battery module 100 provided in this application includes a plurality of the battery cell components 10 and a plurality of the support members 20. In this embodiment, the battery module 100 is composed of a plurality of the battery cell components 10, and the structures, shapes, and sizes of each battery cell component 10 may be the same or different. The plurality of battery cell components 10 are stacked in sequence along their thickness direction, so that the plurality of battery cell components 10 are integrated into the battery module 100 to improve the compactness of the battery module 100 and reduce the volume of the battery module 100.

[0041] Each support member 20 is disposed between two adjacent battery cell components 10, so that the two adjacent battery cell components 10 are spaced apart. The support member 20 can be used to abut against the battery cell component 10 and apply pressure to the battery cell component 10, which can inhibit the battery cell component 10 from expanding and reduce the probability of the battery module 100 deforming due to the expansion of the battery cell component 10. And, at least part of the battery cell components 10 are disposed between two adjacent support members 20, so that both sides of the battery cell component 10 are subjected to the pressure applied by the support members 20, further inhibiting the battery cell component 10 from expanding and reducing the probability of the battery module 100 deforming due to the expansion of the battery cell component 10. Optionally, in this embodiment, the material of the support member 20 is aluminum alloy. In other embodiments, the material of the support member 20 may also be other metal materials with relatively high hardness and good thermal conductivity, such as copper, silver, or other metal materials, and this application does not limit this.

[0042] The support member 20 includes a plurality of first through holes 201 penetrating the support member 20 in the first direction. In other words, the first through holes 201 are strip-shaped holes. And in this embodiment, the shape of the first through holes 201 is a square hole. In other embodiments, the shape of the first through holes 201 can also be a circular hole or other shapes, and the present application does not limit this. The support member 20 abuts against the battery cell assembly 10 and can be used to conduct the heat of the battery cell assembly 10. And the first through holes 201 formed in the support member 20 are heat dissipation holes. The first through holes 201 communicate with the external environment. Air in the external environment can pass through the first through holes 201, and the flowing air can quickly take away the heat generated by the battery cell assembly 10 during high-rate discharge, and will not stay on the battery cell assembly 10 or the support member 20 to cause the temperature of the battery cell assembly 10 to rise. Furthermore, the operating temperature of the battery module 100 during high-rate discharge can be reduced. For example, in the field of unmanned aerial vehicles, compared with the battery modules in the related art, the operating temperature of the battery module 100 in this embodiment is about 10 degrees lower than that of the battery modules in the related art.

[0043] Further, the support member 20 further includes a plurality of second through holes 202 penetrating the support member 20 in the second direction. In other words, the second through holes 202 are strip-shaped holes. And in this embodiment, the shape of the second through holes 202 is a square hole. In other embodiments, the shape of the second through holes 202 can also be a circular hole or other shapes, and the shape of the first through holes 201 and the shape of the second through holes 202 can be the same or different, and the present application does not limit this. The second through holes 202 formed in the support member 20 are also heat dissipation holes. The second through holes 202 communicate with the external environment. Air in the external environment can pass through the second through holes 202, and the flowing air can quickly take away the heat generated by the battery cell assembly 10 during high-rate discharge, and will not stay on the battery cell assembly 10 or the support member 20 to cause the temperature of the battery cell assembly 10 to rise. Furthermore, the operating temperature of the battery module 100 during high-rate discharge can be reduced. The first through holes 201 and the second through holes 202 communicate with each other. The first through holes 201 and the second through holes 202 are jointly arranged in the support member 20. Both the first through holes 201 and the second through holes 202 can be used to allow air in the external environment to enter and quickly transfer the heat of the battery cell assembly 10, which is beneficial to further reducing the operating temperature of the battery module 100 during high-rate discharge and improving the heat dissipation effect of the battery module 100.

[0044] It should be noted that the first through hole 201 extends along the first direction, and the second through hole 202 extends along the second direction. In this embodiment, both the first direction and the second direction are perpendicular to the thickness direction, and the first direction is perpendicular to the second direction. In other embodiments, the first direction and the second direction may also intersect and the included angle is greater than 0° and less than 180°, and the present application does not limit this.

[0045] In the battery module 100 provided by the present application, each of the support members 20 is disposed between two adjacent battery cell assemblies 10; the support member 20 includes a plurality of first through holes 201 penetrating the support member 20 along the first direction, and the support member 20 further includes a plurality of second through holes 202 penetrating the support member 20 along the second direction. The first through holes 201 communicate with the second through holes 202. Both the first direction and the second direction are perpendicular to the thickness direction, and there is an included angle between the first direction and the second direction. The support member 20 can be used to abut against the battery cell assembly 10 and apply pressure to the battery cell assembly 10, which can inhibit the battery cell assembly 10 from swelling and reduce the probability of the battery module 100 deforming due to the swelling of the battery cell assembly 10. And the first through holes 201 and the second through holes 202 can be used to allow air in the external environment to enter and quickly transfer the heat of the battery cell assembly 10, which is beneficial to reducing the working temperature of the battery module 100 during high-rate discharge and improving the heat dissipation effect of the battery module 100.

[0046] Please refer to Figure 1 and Figure 4 , Figure 4 which is a schematic structural diagram of a fixing member provided by an embodiment of the present application. In one embodiment, the battery module 100 further includes a plurality of fixing members 30. The fixing members 30 surround the outer peripheries of the plurality of battery cell assemblies 10 and the plurality of support members 20 in the thickness direction of the battery module 100, and the fixing members 30 are used to fix the plurality of battery cell assemblies 10 and the plurality of support members 20.

[0047] Specifically, in the present embodiment, the fixing member 30 includes a first fixing portion 31, a second fixing portion 32, a third fixing portion 33, a fourth fixing portion 34, and a fifth fixing portion 35. The first fixing portion 31 is disposed on the upper surface of the plurality of cell assemblies 10. The second fixing portion 32 and the third fixing portion 33 are respectively connected to both sides of the first fixing portion 31. The extending directions of the second fixing portion 32 and the third fixing portion 33 are the same and perpendicular to the first fixing portion 31, and the second fixing portion 32 and the third fixing portion 33 are respectively disposed on both sides of the plurality of cell assemblies 10. The fourth fixing portion 34 is connected to an end of the second fixing portion 32 away from the first fixing portion 31, and the fifth fixing portion 35 is connected to an end of the fourth fixing portion 34 away from the first fixing portion 31. The fourth fixing portion 34 and the fifth fixing portion 35 are parallel to the first fixing portion 31 and disposed on the lower surface of the plurality of cell assemblies 10. Moreover, one end of the fourth fixing portion 34 away from the second fixing portion 32 and one end of the fifth fixing portion 35 away from the third fixing portion 33 are spaced apart. The interval between the fourth fixing portion 34 and the fifth fixing portion 35 of the fixing member 30 enables the fixing member 30 to expand toward both sides, so as to facilitate sleeving the fixing member 30 on the outer periphery of the plurality of cell assemblies 10, and enables the fixing member 30 to fix the plurality of cell assemblies 10 and apply pressure to the plurality of cell assemblies 10, so as to inhibit the plurality of cell assemblies 10 from expanding and deforming, and reduce the probability of deformation of the battery module 100 caused by the expansion of the cell assemblies 10.

[0048] Optionally, in the present embodiment, the material of the fixing member 30 is aluminum alloy. In other embodiments, the material of the fixing member 30 can also be other metal materials with relatively high hardness and good thermal conductivity, such as copper, silver, or other metal materials. The present application does not limit this.

The first reinforcing member 41 is disposed on a side of the first battery cell assembly 101 facing away from the second battery cell assembly 102. The first reinforcing member 41 is used to abut against the first battery cell assembly 101. The first reinforcing member 41 can be used to provide continuous pressure to the plurality of battery cell assemblies 10, inhibit the battery cell assemblies 10 from expanding, and effectively ensure the performance of the battery cell assemblies 10. Similarly, the second reinforcing member 42 is disposed on a side of the second battery cell assembly 102 facing away from the first battery cell assembly 101.

The first buffer member 51 can be used for heat insulation to prevent the heat generated by the operation of the plurality of battery cell assemblies 10 from being conducted to the first reinforcing member 41 and the fixing member 30. Moreover, the first buffer member 51 can also be used to prevent the relatively hard first reinforcing member 41 from directly contacting the first battery cell assembly 101 and damaging the first battery cell assembly 101. Similarly, the second buffer member 52 is disposed between the second reinforcing member 42 and the second battery cell assembly 102. The second buffer member 52 includes protective foam. The second buffer member 52 can be used for heat insulation to prevent the heat generated by the operation of the plurality of battery cell assemblies 10 from being conducted to the second reinforcing member 42 and the fixing member 30. Moreover, the second buffer member 52 can also be used to prevent the relatively hard second reinforcing member 42 from directly contacting the second battery cell assembly 102 and damaging the second battery cell assembly 102.

The adapter 60 is a component for connecting multiple tab ears 12, which is used to electrically connect all the tab ears 12 together to form a whole, thereby facilitating the connection to an external circuit for power supply. The adapter 60 is rectangular in shape and is provided with a plurality of through holes slightly larger than the width of the tab ears 12. During use, the multiple tab ears 12 are fixed to the adapter 60, and thus the tab ears 12 of the multiple cell assemblies 10 are aggregated together, simplifying the layout of the wire lines.

When the drone needs to be powered, the battery module 100 can be electrically connected to the circuit system of the drone, so as to complete a series of flight actions.

[0062] Specifically, when the drone is flying, the airflow generated by the flight passes through the drone housing 200 and enters the battery module 100. The flowing airflow passes through the first through hole 201 and the second through hole 202 of the support member 20, and then flows out from the housing 200, taking away the heat on the surface of the cell assembly 10 and reducing the overall temperature of the battery module 100.

[0063] In one embodiment, the housing 200 has an air inlet hole 210 and an air outlet hole 220 that connect the first through hole 201 and the second through hole 202 in the battery module 100.

When the electronic device 1000, such as a drone, is operating, external air enters the first through hole 201 and the second through hole 202 of the support member 20 in the battery module 100 through the air inlet hole 210, and then flows out through the air outlet hole 220.

[0064] In the electronic device 1000 provided in this application, each support member 20 is disposed between two adjacent battery cell assemblies 10; the support member 20 includes a plurality of first through holes 201 penetrating the support member 20 in a first direction, and the support member 20 further includes a plurality of second through holes 202 penetrating the support member 20 in a second direction. The first through holes 201 communicate with the second through holes 202. Both the first direction and the second direction are perpendicular to the thickness direction, and there is an included angle between the first direction and the second direction. The support member 20 can be used to abut against the battery cell assembly 10 and apply pressure to the battery cell assembly 10, which can inhibit the expansion of the battery cell assembly 10 and reduce the probability of deformation of the battery module 100 caused by the expansion of the battery cell assembly 10. Moreover, the first through holes 201 and the second through holes 202 can be used to allow air in the external environment to enter and quickly transfer the heat of the battery cell assembly 10, which is beneficial to reducing the operating temperature of the battery module 100 during high-rate discharge and improving the heat dissipation effect of the battery module 100.
