Collection assembly, battery pack, and vehicle

Abstract

The present application provides a collection assembly, a battery pack, and a vehicle. The collection assembly comprises flexible circuit boards, components, and a first framework. The components are connected to the flexible circuit boards; first accommodating recesses are provided in the first framework; the flexible circuit boards are connected to the first framework; and the components are located in the first accommodating recesses. Therefore, when an adhesive enters the first accommodating recesses to cover the components, the adhesive covering the components is located in the first accommodating recesses, i.e., the adhesive covering the components is fitted into the first framework such that the adhesive and the first framework form an integral structure, thereby enabling the components located inside the adhesive and the first framework to form an integral structure. Therefore, during compression of a battery pack, a tensile force applied by an adhesive onto components is dispersed to a first framework and converted into a tensile force between the first framework and flexible circuit boards, thereby reducing the force between the components and the flexible circuit boards, lowering the risk of detachment of the components from the flexible circuit boards, and prolonging the service life of the battery pack.

Description

Data acquisition components, battery packs, and vehicles

[0001] This application claims priority to Chinese Patent Application No. 202411563501.0, filed on November 5, 2024, entitled "Collection Component, Battery Pack and Vehicle", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to, but is not limited to, the field of battery technology, and particularly to a data acquisition component, a battery pack, and a vehicle. Background Technology

[0003] In some technologies, expanding foam is filled inside the battery pack casing to enhance its strength and connect the internal components into a unified whole. However, when the battery pack is compressed and deformed, the expanding foam also deforms. For some data acquisition components using flexible circuit boards, the solder joints between the components and the flexible circuit board are relatively fragile due to the thinness of the circuit board itself. Therefore, during the deformation of the expanding foam, it can easily pull on the components connected to the flexible circuit board, causing them to detach and resulting in a shorter battery pack lifespan.

[0011] The data acquisition component according to the embodiments of this application has at least the following beneficial effects:

[0012] In this embodiment, the flexible circuit board is connected to the first frame, and the components are located in the first receiving groove of the first frame. Therefore, when the acquisition component of this embodiment is used in a battery pack, when the adhesive enters the first receiving groove and wraps the components, the adhesive wrapping the components is located within the first receiving groove. That is, the adhesive wrapping the components is snapped into the first frame and forms a whole with the first frame, thereby making the components located inside it form a whole with the first frame. Therefore, during the pressure process of the battery pack, the tensile force exerted by the adhesive on the components will be dispersed to the first frame and converted into a tensile force between the first frame and the flexible circuit board, thereby reducing the force between the components and the flexible circuit board and reducing the risk of the components detaching from the flexible circuit board. Therefore, when the acquisition component of this embodiment is used in a battery pack, the service life of the battery pack can be improved.

When adhesive enters the first receiving groove and includes the components, the adhesive wrapping the components is located within the first receiving groove, that is, the adhesive wrapping the components is snapped into the first frame and forms a whole with the first frame, thereby making the components located inside it form a whole with the first frame. Therefore, during the pressure process of the battery pack, the tensile force exerted by the adhesive on the components is dispersed to the first frame and converted into a tensile force between the first frame and the flexible circuit board, thereby reducing the force between the components and the flexible circuit board, reducing the risk of the components detaching from the flexible circuit board, and thus improving the service life of the battery pack in this embodiment.

When adhesive enters the first receiving groove and includes the components, the adhesive wrapping the components is located within the first receiving groove, that is, the adhesive wrapping the components is snapped into the first frame and forms a whole with the first frame, thereby making the components located inside the battery pack and the first frame a whole. Therefore, during the pressure process of the battery pack, the tensile force exerted by the adhesive on the components is dispersed to the first frame and converted into a tensile force between the first frame and the flexible circuit board, thereby reducing the force between the components and the flexible circuit board, reducing the risk of the components detaching from the flexible circuit board, improving the service life of the battery pack of this embodiment, and thus reducing the maintenance cost of the vehicle.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0046] In some technologies, expanding foam is filled inside the battery pack casing to enhance its strength and connect the internal components into a unified whole. However, when the battery pack is compressed and deformed, the expanding foam also deforms. For some data acquisition components using flexible circuit boards, the solder joints between the components and the flexible circuit board are relatively fragile due to the thinness of the circuit board itself. Therefore, during the deformation of the expanding foam, it can easily pull on the components connected to the flexible circuit board, causing them to detach and resulting in a shorter battery pack lifespan.

[0047] Based on the above problems, this embodiment proposes a data acquisition component that can improve the service life of pouch batteries. Referring to Figures 1 and 2, Figure 1 is a structural schematic diagram of the data acquisition component according to the first aspect of this application, and Figure 2 is an enlarged schematic diagram of region A in Figure 1. The data acquisition component of this embodiment includes a flexible circuit board 100, components 200, and a first frame 300.

[0048] Components 200 include, for example, a data acquisition chip, a capacitor, or a resistor, and are connected to the flexible circuit board 100. The first frame 300 has a first receiving groove 310, and the flexible circuit board 100 is connected to the first frame 300, with components 200 located within the first receiving groove 310. The first frame 300 can be, for example, a metal structure or a non-metallic insulating structure. When the first frame 300 is a non-metallic insulating structure, it can also serve as a wire harness isolation mechanism, insulating the flexible circuit board 100 from other structures in the battery pack.

[0049] Specifically, the flexible circuit board 100 is connected to the first frame 300, and the component 200 is located within the first receiving groove 310 of the first frame 300. Therefore, when the acquisition component of this embodiment is used in a battery pack, when adhesive enters the first receiving groove 310 and wraps the component 200, the adhesive wrapping the component 200 (for ease of description, unless otherwise specified, the portion of adhesive wrapping the component 200 is referred to as the first adhesive) is located within the first receiving groove 310. That is, the first adhesive is snapped into the first frame 300 and forms a whole with the first frame 300, thereby making the component 200 located inside the first adhesive and the first frame 300 form a whole. Therefore, the tensile force exerted by the adhesive on the component 200 will be dispersed to the first frame 300 and converted into a tensile force between the first frame 300 and the flexible circuit board 100, thereby reducing the force between the component 200 and the flexible circuit board 100 and reducing the risk of the component 200 detaching from the flexible circuit board 100. Therefore, when the acquisition component of this embodiment is used in a battery pack, the lifespan of the battery pack can be improved.

[0050] Furthermore, since the adhesive portion is located within the first receiving groove 310, that is, the adhesive portion is snapped into the first frame 300, the connection strength between the adhesive and the first frame 300 is improved, thereby increasing the strength of the battery pack.

[0051] In some embodiments, the first receiving groove 310 is configured as a blind hole in the first frame 300. The flexible circuit board 100 is connected to the first frame 300 and seals the first receiving groove 310. This prevents adhesive from entering the first receiving groove 310 when the acquisition component of this embodiment is used in a battery pack. Therefore, the component 200 is not stretched during the deformation of the adhesive, thus preventing the component 200 from falling off.

[0052] In some embodiments, along the thickness direction of the first frame 300, the size of the first receiving groove 310 is larger than the size of the component 200, meaning that the component 200 is completely located within the first receiving groove 310. Therefore, during the process of applying pressure to the acquisition component with adhesive, the pressure is mainly concentrated on the first frame 300, while reducing the pressure on the component 200, thereby reducing damage to the component 200 and improving the service life of the acquisition component.

[0053] Referring to Figure 1, in some embodiments, the first frame 300 includes a first frame portion 320 and a second frame portion 330 that do not overlap. The flexible circuit board 100 is connected to the first frame portion 320. The second frame portion 330 has a first channel 331 extending along its own thickness direction. The first channel 331 is used for the flow of adhesive, and its number can be set to any number, such as one, two, or three, depending on the area of ​​the first frame 300. When the acquisition component of this embodiment is used in a battery, the adhesive can flow through the first channel 331, thereby allowing the adhesive to more fully fill the entire housing 600 of the battery pack, thus improving the strength of the battery pack. For example, when the data acquisition component of this embodiment is used in a battery pack, the data acquisition component is located between the battery pack 700 and the cover 620 of the battery pack. In conventional technology, expanding foam usually enters the space between the cover 620 and the data acquisition component through the edge of the data acquisition component. However, in this embodiment, the first frame 300 has a first channel 331, through which adhesive can enter the space between the data acquisition component and the cover 620, making the adhesive between the data acquisition component and the cover 620 more fully filled, thereby improving the strength of the battery pack and thus extending its service life. In addition, heat transfer can be carried out between the data acquisition component and the cover 620 through the adhesive, thereby improving the heat dissipation performance of the data acquisition component and enhancing the safety of the battery pack.

[0054] It should be noted that when the collection component of this embodiment is used in the battery pack, it is not limited to being set between the cover 620 and the battery pack 700. It can also be set between the battery pack 700 and the side wall of the housing 600, that is, the collection component is set on the side of the battery pack 700. In some cases, it can also be set inside the battery pack 700, that is, between the individual cells 710. Regardless of where the collection component is set, the first channel 331 can make the adhesive inside the battery pack flow more easily and fill more fully.

[0055] Referring to Figure 2, based on the above embodiment, the first skeleton portion 320 has a second channel 321 extending along its own thickness direction, and the flexible circuit board 100 has a third channel 110 extending along its own thickness direction. The third channel 110 is connected to the second channel 321. Therefore, when the acquisition component of this embodiment is used in a battery pack, the adhesive can flow through the third channel 110 and the second channel 321, which can further make the adhesive fill more fully. In addition, the second channel 321 is connected to the third channel 110, that is, when used in a battery pack, the adhesive will enter the second channel 321 and the third channel 110, so that the adhesive can directly contact the flexible circuit board 100, thereby improving the heat dissipation performance of the flexible circuit board 100.

[0056] Referring to Figure 2, in some embodiments, the first frame portion 320 has a plurality of second channels 321, at least a portion of the second channels 321 being first receiving grooves 310. That is, the number of second channels 321 can be greater than or equal to the number of components 200. When the number of components 200 is equal to the number of second channels 321, each second channel 321 contains one component 200. When the number of second channels 321 is greater than the number of components 200, only a portion of the second channels 321 contains components 200. Specifically, in this embodiment, the second channels 321 are used both to accommodate components 200 and to allow adhesive to flow, thereby simplifying the structure of the first frame 300, making processing easier, and reducing the manufacturing cost of the first frame 300. Furthermore, when the acquisition component of this embodiment is used in a battery pack, heat transfer occurs between the components 200 and the housing 600 via adhesive, allowing the heat from the components 200 to be directly transferred to the housing 600, thereby improving the heat dissipation efficiency of the components 200.

[0057] Referring to Figure 3, which is a schematic diagram of Figure 1 from another perspective, in some embodiments, the first skeleton 300 has a first surface 340, which includes a non-overlapping first connection area 341 and a second connection area 342. The flexible circuit board 100 is connected to the first connection area 341. The acquisition component also includes a second skeleton 400, the thickness of which is not less than the thickness of the flexible circuit board 100, and the second skeleton 400 is connected to the second connection area 342. Specifically, the second skeleton 400 is made of materials with high mechanical strength, such as FR4 (a general term for composite insulating materials, mainly composed of epoxy resin, fiber fillers, and fillers, etc., with strong mechanical strength and insulation properties), carbon fiber, or advanced ceramics. The thickness of the second skeleton 400 is not less than the thickness of the flexible circuit board 100. For example, the thickness of the second skeleton 400 is greater than the thickness of the flexible circuit board 100, causing the second skeleton 400 to protrude from the flexible circuit board 100. Therefore, when the acquisition component of this embodiment is used in a battery pack, the second frame 400 can contact other components (such as the connecting component 800 in the following embodiment), thus preventing the flexible circuit board 100 from being crushed. When the thickness of the second frame 400 is equal to the thickness of the flexible circuit board 100, the second frame 400 and the flexible circuit board 100 jointly contact other components, and the second frame 400 provides a certain supporting function to prevent the flexible circuit board 100 from being crushed, thereby improving the service life of the battery pack. Correspondingly, in some embodiments, the second frame 400 is provided with a fifth channel 410 at the position corresponding to the first channel 331, and the fifth channel 410 is connected to the first channel 331 to allow adhesive to flow.

[0058] Referring to Figures 1, 4 to 6, Figure 4 is an enlarged schematic diagram of region B in Figure 1, Figure 5 is a structural schematic diagram of the battery pack according to the second aspect embodiment of this application, and Figure 6 is a structural schematic diagram of the first frame, cover and support member in Figure 5. In some embodiments, the first frame 300 has a second surface 350 facing away from the flexible circuit board 100. The acquisition component also includes a support member 500. The support member 500 is, for example, a cylindrical structure, a prismatic structure or any other arbitrary shape. The support member 500 is connected to the second surface 350 and protrudes from the second surface 350 along a first direction (the first direction is the direction from the flexible circuit board 100 to the first frame 300). When the data acquisition component of this embodiment is used in a battery pack, the support member 500 abuts against the battery pack housing 600. Taking Figure 6 as an example, the support member abuts against the cover 620, ensuring sufficient space between the first frame 300 and the cover 620 for adhesive filling. This allows for more thorough adhesive filling between the data acquisition component and the cover 620, resulting in a stronger bond between the first frame 300 and the cover 620. Furthermore, when the housing 600 is a metal structure, the electrical safety distance between the connecting component 800 and the cover 620 can be adjusted using the dimensions of the support member 500 without thickening or thinning the first frame 300, thus improving material utilization.

[0059] Based on the above embodiments, the support member 500 and the first frame 300 are an integral structure. Exemplarily, the support member 500 and the first frame 300 are integrally manufactured using 3D printing technology, machining, or injection molding. Therefore, during assembly, the assembly steps of the support member 500 and the first frame 300 can be omitted, thereby improving the assembly efficiency of the acquisition component. Furthermore, by integrally manufacturing, the consistency of the support members 500 can be improved, ensuring that each support member 500 is in contact with the battery pack housing 600 as much as possible. Therefore, when the housing 600 is subjected to pressure, the first frame 300 can be subjected to more even stress, thereby reducing the risk of damage to the first frame 300 and improving the service life of the battery pack.

[0060] In some embodiments, the support member 500 and the first frame 300 are separate structures. Exemplarily, the support member 500 and the first frame 300 are connected to the first frame 300 by threaded connection, insertion, or snap-fit. Therefore, the support member 500 and the first frame 300 can be processed separately. Specifically, it is understood that the first frame 300 plays a reinforcing role in the acquisition component, thus requiring sufficient strength. The support member 500, on the other hand, only needs to ensure sufficient clearance between the first frame 300 and the housing 600 when filling the adhesive, and its strength requirements are lower. Therefore, the first frame 300 can be made of materials with high mechanical strength, such as FR4 (a general term for composite insulating materials, mainly composed of epoxy resin, fiber fillers, and fillers, possessing high mechanical strength and insulation properties), carbon fiber, or advanced ceramics. The support member 500, however, can be made of lower-cost materials such as nylon, rubber, or polyurethane, which have relatively lower strength, thereby reducing the manufacturing cost of the acquisition component.

[0061] Referring to FIG5, the battery pack of the second aspect embodiment of this application includes a housing 600, a battery pack 700, an adhesive, and a collection component of the first aspect embodiment. The housing 600 includes a cover 620 and a shell 610. The cover 620 is connected to the shell 610 and together with the shell 610 forms a receiving cavity. Exemplarily, the shell 610 has a second receiving groove 611 and a slot 612 communicating with the second receiving groove 611. The cover 620 has a flat plate structure, is connected to the shell 610, and covers the second slot 612. The surface of the cover 620 facing the second receiving groove 611 and the inner wall of the second receiving groove 611 enclose the receiving cavity. Alternatively, in some embodiments, the cover 620 has a third receiving groove, and the inner wall of the third receiving groove and the inner wall of the second receiving groove 611 together enclose the receiving cavity.

[0062] The battery pack 700 includes multiple individual cells 710 arranged in an array. Each individual cell 710 can be, for example, a prismatic cell, a cylindrical cell, or a blade cell. The battery pack 700 is located within a receiving cavity. A data acquisition component is located within the receiving cavity and electrically connected to each individual cell 710. This component is used to acquire parameter signals from each individual cell 710, including parameters such as voltage, current, temperature, or capacity. Adhesive fills the receiving cavity to improve the strength of the battery pack. The flexible circuit board 100 in the data acquisition component is connected to a first frame 300. Components 200 are located within a first receiving groove 310 of the first frame 300. When adhesive enters the first receiving groove 310 and wraps around the component 200, the adhesive wrapping the component 200 is located within the first receiving groove 310. In other words, the first adhesive is engaged within the first frame 300 and forms a single unit with the first frame 300, thus making the component 200 located within the first adhesive and the first frame 300 a single unit. Therefore, the tensile force exerted by the adhesive on the component 200 will be dispersed to the first frame 300 and converted into a tensile force between the first frame 300 and the flexible circuit board 100, thereby reducing the force between the component 200 and the flexible circuit board 100, reducing the risk of the component 200 detaching from the flexible circuit board 100, and thus improving the service life of the battery pack in this embodiment.

[0063] It should be noted that this embodiment adopts all the technical features of the acquisition component of the first aspect embodiment. Therefore, this embodiment has all the beneficial effects brought by the first aspect embodiment, which will not be repeated here.

[0064] Referring to Figures 5, 7, and 8, Figure 7 is a structural schematic diagram of the connecting assembly in Figure 5, and Figure 8 is an enlarged view of region C in Figure 7. In some embodiments, the battery pack further includes a connecting assembly 800 (as shown in Figure 5). The connecting assembly 800 includes a third frame 810 and a plurality of connecting pieces 820. The connecting pieces 820 are, for example, copper plates or aluminum busbars. The connecting pieces 820 are connected to the third frame 810 and to the battery pack 700, so that the individual cells 710 are electrically connected in series or in parallel. For example, taking a cylindrical battery as an example, the individual cell 710 includes a casing 711 and a terminal 720, wherein the casing 711 is connected to the internal anode as the negative electrode. When adjacent individual cells 710 are connected in series, one end of the connecting piece 820 is connected to the terminal 720 of one individual cell 710, and the other end is connected to the casing 711 of the individual cell 710. When adjacent batteries are connected in parallel, the two ends of the connecting piece 820 are connected to the same electrode of the two individual batteries 710, for example, both are connected to the battery casing 711, or both are connected to the battery terminal 720. It should be noted that, in the embodiments, the connection between individual batteries 710 is not limited to a single series or parallel connection; it can also be a partial series connection and a partial parallel connection. The third frame 810 has a fourth channel 811 extending along its own thickness direction (as shown in Figure 8), and part of the adhesive is filled in the fourth channel 811. That is, when filling the adhesive, the adhesive can flow through the fourth channel 811. For example, in some embodiments, the collection component is located between the cover 620 and the connecting component 800, and the fourth channel 811 connects to the first channel 331, the second channel 321, and the third channel 110 in the collection component, thereby allowing the adhesive to more fully fill and accommodate the cavity, improving the strength of the battery pack in this embodiment.

[0065] Referring to Figures 9 and 10, in some embodiments, the battery pack further includes multiple limiting members 900, with at least one limiting member 900 connected to the third frame 810. The individual battery cell 710 includes a housing 711 and a terminal post 720. The housing 711 has a first side 7111 and a second side 7112. The terminal post 720 is connected to the first side 7111. A connecting assembly 800 is located on the first side 7111 of the individual battery cell 710. The limiting member 900 is connected to the third frame 810 (as shown in Figure 9) and abuts against the second side 7112 (as shown in Figure 10), thereby defining the relative position of the connecting piece 820 and the individual battery cell 710.

[0066] Specifically, it is understandable that, in order to ensure that the single cell 710 has a high energy density, the protrusion of the terminal post 720 from the outer casing 711 is relatively small. Therefore, when the third frame 810 is set on the first side 7111, the space between the third frame 810 and the first side 7111 is small. If the terminal post 720 is used as the positioning structure on the single cell 710, the limiting member 900 needs to be located between the first side 7111 and the third frame 810, which not only increases the installation difficulty of the limiting member 900, but also increases the processing difficulty of the limiting member 900. Specifically, because the space between the third frame 810 and the first side 7111 is narrow, it is difficult to observe the positioning during installation, which is not conducive to assembly. If the thickness of the limiting member 900 is too large, it will push up the third frame 810, causing the connecting piece 820 to separate from the single cell 710. If the thickness of the limiting member 900 is too small, it is easy to cause positioning failure. This embodiment effectively improves this problem. In this embodiment, the limiting member 900 abuts against the second side 7112, so that the installation of the limiting member 900 and the installation of the third frame 810 in the first direction do not interfere with each other. Therefore, the size of the limiting member 900 is not limited by the distance between the third frame 810 and the first side 7111, thereby reducing the processing requirements of the limiting member 900 and thus reducing manufacturing costs.

[0067] Referring to Figure 10, in some embodiments, the single battery cell 710 is a cylindrical battery, the second side surface 7112 is a cylindrical surface, and the limiting member 900 has an arc-shaped limiting surface 910 adapted to the second side surface 7112, the limiting surface 910 abutting against the second side surface 7112. Specifically, it can be understood that the limiting surface 910 is a concave curved surface, which can limit the displacement of the third frame 810 and the battery pack 700 in multiple directions, thereby realizing the positioning of the third frame 810 and the battery pack 700 in multiple directions, thus making the structure of the battery pack in this embodiment simpler and reducing manufacturing costs.

[0068] Referring to Figures 1 and 9, in some embodiments, the limiting member 900 includes, for example, a connecting portion 920. The third frame 810 has a first limiting hole 812, and the connecting portion 920 is inserted into the first limiting hole 812 (as shown in Figure 9). When the connecting portion 920 is a cylindrical structure, the limiting member 900 includes at least two connecting portions 920, thereby preventing the limiting member 900 from rotating relative to the third frame 810 and improving the positional accuracy between the limiting member 900 and the third frame 810. Further, in some embodiments, the acquisition component is located on the side of the connecting component 800 opposite to the battery pack 700. The third frame 810 has a through first limiting hole 812, and the first frame 300 has a second limiting hole 360 ​​(as shown in Figure 1). The connecting portion 920 passes through the first limiting hole 812 and is inserted into the second limiting hole 360 ​​to achieve the positioning of the acquisition component. Therefore, in this embodiment, the positioning of the connecting component 800 and the acquisition component and the battery pack 700 can be achieved by using a limiting component 900, thereby making the battery pack structure of this embodiment simpler and reducing manufacturing costs.

[0069] The vehicle in the third aspect embodiment of this application can be a private car, such as a sedan, SUV, MPV, or pickup truck. The vehicle can also be a commercial vehicle, such as a van, bus, small truck, or large trailer. The vehicle can be a hybrid electric vehicle or a pure electric vehicle. The vehicle in this embodiment includes the battery pack of the second aspect embodiment. In the battery pack, the flexible circuit board 100 is connected to the first frame 300, and the component 200 is located within the first receiving groove 310 of the first frame 300. Therefore, when adhesive enters the first receiving groove 310 and wraps around the component 200, the adhesive wrapping the component 200 is located within the first receiving groove 310, that is, the first adhesive is snapped into the first frame 300 and forms a whole with the first frame 300, thereby making the component 200 located inside the first adhesive form a whole with the first frame 300. Therefore, the tensile force exerted by the adhesive on the component 200 will be dispersed to the first frame 300 and converted into a tensile force between the first frame 300 and the flexible circuit board 100, thereby reducing the force between the component 200 and the flexible circuit board 100, reducing the risk of the component 200 detaching from the flexible circuit board 100, thereby improving the service life of the battery pack in this embodiment and reducing the maintenance cost of the vehicle.
