[0032] Hereinafter, a battery assembly, a battery assembly and an electronic device provided by the application are described in detail by listing specific embodiments.

[0033] Figure 1 is a schematic diagram of a battery assembly in an embodiment of the application, Figure 2 is a schematic diagram of a battery assembly injection process in an embodiment of the application, Figure 3 is a schematic diagram of a component part in a battery assembly injection process in an embodiment of the application, with reference to Figures 1 to 3 A battery assembly provided by an embodiment of the application comprises: a bracket 1; a circuit board 2 arranged on the bracket 1; and an avoiding part 20 arranged on the circuit board 2, which is used for extending an injection pipe 5 from a side of the circuit board 2 away from the bracket 1 into a space between the circuit board 2 and the bracket 1.

[0034] Specifically, the bracket 1 is mainly used for supporting the battery monomer 4 and the circuit board 2 and other related control components connected with the battery monomer 4, so as to avoid the battery monomer 4 and the related control components from shaking or deviating during the working process, thereby reducing the probability of short circuit and other problems of the battery. The bracket 1 can be a plastic bracket 1 processed by polyamide, polypropylene, polycarbonate and other materials, which has good corrosion resistance and insulation, and can effectively electrically isolate the battery monomer 4 and the circuit board 2. The bracket 1 can also be a composite material bracket 1 processed by glass fiber reinforced polyamide and other materials, which has more excellent strength and rigidity, and can more stably support the battery monomer 4 and the circuit board 2, thereby improving the use reliability and safety of the battery, and also helping to control the cost of the battery preparation and reduce the total weight of the battery.

[0035] The above-mentioned circuit board 2 is a PCB board, the PCB board is provided with integrated circuits and various components 3, the PCB board and the components 3 form a part of a battery management system, wherein the PCB board is electrically connected with the battery monomer 4, the components 3 are in thermal contact with the battery monomer 4, and the integrated circuits and various components 3 can monitor and manage the current, voltage, temperature and the like in the working process of the battery monomer 4, so as to maintain the normal working of the battery monomer 4. Among them, the components 3 include NTC (Negative Temperature Coefficient, negative temperature coefficient) thermistor, the resistance of the NTC thermistor decreases with the increase of temperature, which can be used to detect the working temperature of the battery monomer 4. In the preparation of the battery, it is necessary to inject the thermal conductive glue 6 on the NTC thermistor and the battery monomer 4 to establish the thermal conductive connection between the NTC thermistor and the battery monomer 4. However, in some batteries, the NTC thermistor is arranged between the PCB board and the support 1, and when gluing, the thermal conductive glue 6 is usually injected on the surface of the PCB board where the NTC thermistor is located, and then the PCB board is turned over to inject the thermal conductive glue 6, which leads to a relatively complicated gluing process, low gluing efficiency, and affects the preparation efficiency and preparation cost of the battery.

[0036] As shown in Figure 1 The battery assembly of the embodiment of the application is provided with an avoiding portion 20 on the circuit board 2, the avoiding portion 20 is used for the injection glue pipe 5 to extend into the space between the circuit board 2 and the support 1 from the side of the circuit board 2 away from the support 1, Figure 2 The head 51 of the injection glue pipe 5 is shown in the schematic diagram of the avoiding portion 20, wherein the injection glue pipe 5 is a tool specially used for injecting the thermal conductive glue 6, and the injection glue pipe 5 is used to ensure that the thermal conductive glue 6 can be accurately and efficiently applied to the NTC thermistor and the battery monomer 4. The injection glue pipe 5 is usually composed of a pipe body, an injection head, a piston and the like, the pipe body is used for containing the thermal conductive glue 6, the injection head is used for accurately injecting the thermal conductive glue 6 to the target position, and the piston is used for pushing the thermal conductive glue 6 to move forward to realize the injection function, the head 51 of the injection glue pipe 5 refers to the injection head of the injection glue pipe 5, and it needs to be explained that the injection head of the injection glue pipe 5 in the embodiment of the application is made of flexible material and has good deformation ability, which can be deformed adaptively based on the shape of the avoiding portion 20 and the space structure of the circuit board 2 and the support 1, so as to ensure that the injection glue pipe 5 can be smoothly inserted into the space between the circuit board 2 and the support 1 to inject the glue.

[0037] Therefore, in the gluing process of the NTC thermistor of the battery assembly of the embodiment of the application, the circuit board 2 does not need to be turned over, the head 51 of the injection glue pipe 5 is inserted into the space between the circuit board 2 and the support 1 from the avoiding portion 20, and the thermal conductive glue 6 can be directly injected to the NTC thermistor and the battery monomer 4, the operation process is simple and convenient, the gluing efficiency of the NTC thermistor and the battery monomer 4 can be effectively improved, and the preparation efficiency and the preparation cost of the battery can be improved.

[0038] Of course, the above is only exemplary description of NTC thermistor as component 3, the component 3 on the circuit board 2 can also be other devices connected to the circuit board 2 near the side of the support 1, such as connectors, sensors, etc., the embodiments of the present application will not be described in more detail. In addition, the connection between the component 3 and the circuit board 2 can be laser welding, fastener assembly connection, adhesive connection, limit clamping, etc. Any way, the embodiments of the present application are not limited.

[0039] In addition, the heat-conducting glue 6 of the embodiments of the present application can use polyurethane heat-conducting glue 6, heat-conducting silicon gel, modified epoxy heat-conducting structural glue, acrylic heat-conducting structural glue, etc., which all have good heat-conducting performance and bonding strength, and have good temperature resistance, insulation and chemical corrosion resistance, which can ensure the reliable connection between the component 3 and the battery monomer 4.

[0040] Optionally, in some embodiments of the present application, the support 1 is provided with a first accommodating cavity 11, Figure 4 is a schematic view of a first accommodating cavity in the embodiments of the present application, referring to Figure 4 The first accommodating cavity 11 is in communication with the avoiding part 20, and the first accommodating cavity 11 is used for accommodating the heat-conducting glue 6 and the component 3. Specifically, the first accommodating cavity 11 is in communication with the avoiding part 20, the head 51 of the glue injection pipe 5 can extend into the first accommodating cavity 11 from the avoiding part 20, the component 3 is arranged in the first accommodating cavity 11, and in the process of injecting the heat-conducting glue 6 by the glue injection pipe 5, the heat-conducting glue 6 is filled in the first accommodating cavity 11 and coated on at least part of the surface of the component 3 and the battery monomer 4.

[0041] The first accommodating cavity 11 can be processed into a rectangular cavity, a circular cavity, a polygonal cavity or any other shape structure, which can be adaptively set according to the position of the component 3 on the support 1, such as Figure 4 The first accommodating cavity 11 in the embodiments of the present application is a rectangular cavity. The first accommodating cavity 11 can limit the flow range of the heat-conducting glue 6, which can effectively avoid the overflow of the heat-conducting glue 6 to the periphery when the injected amount of the heat-conducting glue 6 is too large, thereby avoiding the influence of the heat-conducting glue 6 on other structures or components on other supports 1, and helping to improve the use reliability of the battery.

[0042] Optionally, in some embodiments of the present application, there is a gap between the circuit board 2 and the first accommodating cavity 11, the gap forms the avoiding part 20, and the size of the gap is adaptively set according to the size of the head 51 of the glue injection pipe 5, which can ensure that the head 51 of the glue injection pipe 5 can smoothly extend into the first accommodating cavity 11 from the avoiding part 20. The structure and arrangement position of the circuit board 2 and the first accommodating cavity 11 determine the shape of the gap, such as Figure 1As shown, the avoidance portion 20 in the embodiment of the present application is a gap between the circuit board 2 and the first accommodating cavity 11, and the gap has a rectangular structure to adapt to the first accommodating cavity 11.

[0043] Alternatively, in some other embodiments of the present application, the avoidance portion 20 is a through hole penetrating through the circuit board 2 along the thickness direction of the circuit board 2. In actual processing, the through hole can be processed on the surface of the circuit board 2 by mechanical drilling, laser drilling, chemical etching, and the like. The size of the through hole is adaptively set according to the size of the head 51 of the glue injection pipe 5, so as to ensure that the head 51 of the glue injection pipe 5 can smoothly extend into the first accommodating cavity 11 from the avoidance portion 20.

[0044] The above two methods can form the avoidance portion 20. If the avoidance portion 20 is a gap between the circuit board 2 and the first accommodating cavity 11, the structural integrity of the circuit board 2 can be ensured, and the use performance and reliability of the circuit board 2 can be improved. If the avoidance portion 20 is a through hole on the circuit board 2, the requirements for the structure and position of the first accommodating cavity 11 are lower, and the setting difficulty of the avoidance portion 20 can be reduced.

[0045] Optionally, referring to Figure 1 and Figure 2 In some embodiments of the present application, at least part of the edge of the circuit board 2 protrudes along the width direction of the circuit board 2 to form a protruding portion 21, and at least part of the projection of the protruding portion 21 along the thickness direction of the circuit board 2 is located in the first accommodating cavity 11, and the protruding portion 21 is used to mount the component 3. Specifically, the protruding portion 21 is arranged to protrude along the width direction of the circuit board 2, and the component 3 is mounted on the protruding portion 21. The component 3 can be adhered to the protruding portion 21 by an adhesive to achieve the mounting and fixation of the component 3, so that the approximate position of the component 3 can be positioned by the protruding portion 21, and the subsequent glue injection operation can be easily performed.

[0046] Since the component 3 is arranged in the first accommodating cavity 11, at least part of the projection of the protruding portion 21 along the thickness direction of the circuit board 2 is located in the first accommodating cavity 11, as shown in Figure 1 In the embodiment of the present application, all projections of the protruding portion 21 along the thickness direction of the circuit board 2 are located in the first accommodating cavity 11, so as to control the size of the protruding portion 21 and avoid wasting the material of the circuit board 2, thereby further controlling the preparation cost of the battery.

[0047] Optionally, referring to Figure 1 and Figure 3In some embodiments of the present application, the protrusion 21 is provided with an opening 22 penetrating the protrusion 21 along the thickness direction of the circuit board 2, and the projection of the opening 22 along the thickness direction of the circuit board 2 is located in the first accommodating cavity 11. Since the glue injection pipe 5 may generate a certain amount of heat during the process of injecting the heat-conducting glue 6 into the first accommodating cavity 11, and the components 3 and the battery monomer 4 also generate a certain amount of heat during the working process, the opening 22 can serve as a heat dissipation hole for heat dissipation, thereby reducing the temperature in the first accommodating cavity 11 and avoiding the influence of the overheated temperature environment on the connection of the heat-conducting glue 6, which helps to improve the reliability of the heat-conducting connection between the components 3 and the battery monomer 4.

[0048] At the same time, when the amount of glue injected by the glue injection pipe 5 into the first accommodating cavity 11 is too large, the opening 22 can also serve as a glue overflow port for the excess heat-conducting glue 6 to overflow, thereby maintaining a moderate amount of glue in the first accommodating cavity 11 and improving the connection reliability, and at the same time, it is also convenient for the operator to wipe and clean the excess heat-conducting glue 6 from the side of the circuit board 2 away from the support 1, greatly improving the flexibility of the glue injection process. In addition, the opening 22 can also serve as a visual window for the operator to observe the glue injection state during the glue injection process, so as to control the glue injection speed or glue injection amount as needed.

[0049] The shape and size of the opening 22 can be set in combination with the shape and size of the protrusion 21 and the first accommodating cavity 11, as shown in Figure 1 In the embodiments of the present application, the opening 22 is a strip-shaped hole, and the two ends of the strip-shaped hole are arc-shaped structures to avoid the occurrence of dead angle areas and cause the heat-conducting glue 6 to remain. The size of the opening 22 should not be too large to avoid the overflow of the heat-conducting glue 6 and also to avoid affecting the structural reliability of the circuit board 2.

[0050] Optionally, referring to Figure 4 In some embodiments of the present application, the support 1 is provided with a plurality of baffles 12, and the plurality of baffles 12 are connected to each other to surround the first accommodating cavity 11, and the plurality of baffles 12 respectively abut against the circuit board 2.

[0051] Specifically, the plurality of baffles 12 extend along the thickness direction of the circuit board 2, and the plurality of baffles 12 are connected to each other to surround the first accommodating cavity 11. Since the structure of the surface of the support 1 is different, the size of the plurality of baffles 12 along the thickness direction of the circuit board 2 can be the same or different, as long as the end portions of the plurality of baffles 12 near the circuit board 2 are flush. The plurality of baffles 12 near the circuit board 2 respectively abut against the circuit board 2 to avoid a large gap between the baffles 12 and the circuit board 2, causing the overflow of the heat-conducting glue 6 during the glue injection process, and also to help improve the support reliability of the support 1 for the circuit board 2, avoiding the shaking of the circuit board 2 during the glue injection process, etc.

[0052] The baffle 12 and the support 1 can be designed as an integrally formed structure to save subsequent connection procedures and effectively ensure the connection reliability of the baffle 12 and the support 1. The baffle 12 can also be an independent part and be assembled and connected with the support 1. Further, a plurality of mounting positions for connecting with the baffle 12 can be arranged on the support 1, so that the baffle 12 can be adaptively mounted at different positions of the support 1 according to the positions of the components 3 on the circuit board 2, the position of the first accommodating cavity 11 is adjustable, and the flexibility of battery preparation is improved.

[0053] In addition, the baffle 12 can also be a plastic plate processed from polyamide, polypropylene, polycarbonate or the like, or a composite plate processed from some composite material, which has good corrosion resistance and insulation, avoids electrical contact between the baffle 12 and the components 3 to cause short circuit, improves the use reliability of the battery, and also helps to reduce the weight of the support 1 and control the cost of battery preparation.

[0054] Optionally, referring to Figure 4 In some embodiments of the present application, each baffle 12 is provided with an abutting surface 120 on the side close to the circuit board 2, and the abutting surface 120 is a plane. The plane structure can increase the abutting area of the baffle 12 and the circuit board 2, so that the baffle 12 and the circuit board 2 are fully abutted, the overflow of the heat-conducting glue 6 is effectively avoided, and the support reliability of the baffle 12 for the circuit board 2 is improved.

[0055] Optionally, referring to Figure 4 and Figure 5 In some embodiments of the present application, the support 1 is further provided with a second accommodating cavity 13, and the second accommodating cavity 13 is in communication with the first accommodating cavity 11. The second accommodating cavity 13 is used for accommodating the battery monomer 4. The volume of the second accommodating cavity 13 is much larger than that of the first accommodating cavity 11. The second accommodating cavity 13 is used for accommodating the battery monomer 4. Since a battery assembly usually includes a plurality of battery monomers 4 connected in series or in parallel, the number of the second accommodating cavities 13 on the support 1 is also set to be multiple. The arrangement mode of the second accommodating cavities 13 is set based on the arrangement mode of the plurality of battery monomers 4, Figure 5 The plurality of second accommodating cavities 13 are arranged in parallel as shown in the figure, each second accommodating cavity 13 accommodates one battery monomer 4, and the plurality of battery monomers 4 are arranged in parallel. The second accommodating cavity 13 can limit and fix the battery monomer 4, and improve the structural stability of the battery.

[0056] As shown in Figure 5 The first accommodating cavity 11 is arranged at the edge of the second accommodating cavity 13. Further, one first accommodating cavity 11 can be arranged at the edge of each second accommodating cavity 13, so as to facilitate the heat-conducting connection between the components 3 located between the circuit board 2 and the support 1 and the battery monomer 4.
