DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the utility model 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.

[0041] The battery frame assembly, battery, battery assembly structure and electrical device provided by the embodiments of the utility model are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0042] The utility model embodiment provides a battery frame assembly, referring to Figure 1 and Figure 2 , including a frame 11 and a deformable member 12; the frame 11 has a accommodating space 111, and the accommodating space 111 is suitable for accommodating a battery cell 2; the deformable member 12 is connected to the frame 11, and the deformable member 12 is at least partially located in the accommodating space 111, and the deformable member 12 is deformable and suitable for contacting the battery cell 2, so that the battery cell 2 is confined in the accommodating space 111.

[0043] Specifically, if Figure 1 and Figure 2As shown, the battery frame assembly includes a frame 11 and a deformable member 12. The frame 11 is a battery plastic frame, and its material is an engineering plastic formed by synthesizing ABS (Acrylonitrile-Butadiene-Styrene) and PC (polycarbonate). The frame 11 has a receiving space 111 for accommodating the battery cell 2, such as Figure 1 The accommodation space 111 has openings on both sides perpendicular to the straight surface direction, which are used to load the battery cell 2, and other connection structures and electrical components in the electronic device can be attached to the surface of the battery cell 2. The deformable member 12 is connected to the frame 11 and at least part of the deformable member 12 is located in the accommodation space 111. That is, the deformable member 12 can be connected to the outside of the frame 11 and extend into the accommodation space 111, or the deformable member 12 is connected to the inner surface of the frame 11. Figure 3 , with the length direction of the battery cell as the Z direction and the width direction as the X direction. The deformable member 12 is connected to the first inner side surface 112 and / or the second inner side surface 113 of the frame. When the deformable member 12 is connected to the first inner side surface 112, its elastic deformation direction is along the Z direction, and the displacement and shaking of the battery cell 2 along the Z direction is limited by the elastic force of restoring the deformation, so that the pole ear 21 at the top of the battery cell 2 is connected to the circuit board 13 at the top of the frame, i.e., the third inner side surface 114, and has sufficient welding area to ensure the welding quality; when the deformable member 12 is connected to the second inner side surface 113 of the frame 11, its elastic deformation direction is along the X direction, and the displacement and shaking of the battery cell 2 along the X direction is limited by the elastic force of restoring the deformation, so as to avoid collision and scratching between different battery cells 2. The deformable member 12 has a smooth surface and has strong elasticity and toughness. The material of the deformable member 12 may be consistent with or inconsistent with the material of the frame 11. For example, the deformable member 12 may be integrally formed with the frame 11 by an integral injection molding process, or the deformable member 12 may be separately connected with the frame 11 by processes including but not limited to gluing, fastener connection, or two-color injection molding.

[0044] Specifically, when the battery cell 2 is loaded into the accommodating space 111, the deformable member 12 abuts against the bottom surface and / or side surface of the battery cell 2. When the deformable member 12 is connected to the first inner side surface 112, the deformable member 12 abuts against the bottom surface of the battery cell 2; when the deformable member 12 is connected to the second inner side surface 113, the deformable member 12 abuts against the side surface of the battery cell 2. Exemplarily, the deformable member 12 is connected to the first inner side surface 112, and the force required for the elastic deformation of the deformable member 12 along the Z direction is greater than the weight of the battery cell 2, but when the length dimension of the battery cell 2 is large, the deformable member 12 will be squeezed to deform. Exemplarily, along the Z direction, the dimensional tolerance of the accommodating space 111 is ±0.1mm, and the length dimensional tolerance of the battery cell 2 is +0 / -1mm. In order to avoid that the battery cell 2 at the upper limit tolerance size cannot be loaded into the frame 11, the dimensional tolerance of the accommodating space 111 is determined according to the upper limit value. Based on the length dimension L, the upper limit of the length of the battery cell 2 is L+ΔL1, and the lower limit of the length of the battery cell 2 is L-ΔL2. Figure 4 As shown, when the length of the battery cell 2 is close to the lower limit of the design tolerance, i.e., L-ΔL2, the bottom of the battery cell 2 contacts the deformable member 12, the deformable member 12 does not undergo elastic deformation or undergoes elastic deformation to a small extent, and the battery cell 2 is effectively confined in the frame 11. Figure 5 As shown, the length of the battery cell 2 is close to the upper limit of the design tolerance, i.e., L+ΔL1. The bottom of the battery cell 2 is in contact with the deformable member 12, and the top of the battery cell 2 is in contact with the third inner side surface 114. Since the deformable member 12 has a certain elasticity, the extrusion force of the battery cell 2 causes the deformable member 12 to deform elastically. Under the push of the elastic force of the deformable member 12 itself, the top of the battery cell 2 is in close contact with the limiting structure of the third inner side surface 114, and the battery cell 2 is effectively limited in the frame 11. Figure 6 This reflects the change in the shape of the deformable member 12 during the process of the size of the battery cell 2 changing from small to large. Figure 6 The deformed element 12 on the left reflects Figure 4 The shape of the middle deformation member 12, Figure 6 The right side deformation element 12 reflects Figure 5 The shape of the middle deformation member 12.

[0045] The battery frame assembly provided by the embodiment of the utility model can be deformed, and the elastic force of the self-recovery deformation is used to compensate for the assembly difference between the battery cell and the frame caused by the difference in the size of the battery cell, so that the battery cell is confined in the frame, avoiding the problem of a certain size difference caused by inconsistent battery cell size, especially at the lower limit of the tolerance, that a large gap is easily generated between the battery cell and the frame and the battery cell shakes up and down in the frame, thereby ensuring the stability of the battery cell structure.

[0046] Optionally, the deformable member 12 is a flexible member.

[0047] Specifically, the deformable part 12 is a flexible part that can adapt to the assembly requirements of battery cells of different sizes, including but not limited to plastic, silicone, plastic, resin or fiber. Among them, the optional plastic materials include but are not limited to PVC (Polyvinylchloride), PC, or engineering plastics formed by the synthesis of ABS and PC. Among them, PC plastic material has excellent heat and weather resistance, dimensional stability and impact resistance. The engineering plastics formed by the synthesis of ABS and PC have both the excellent processing fluidity of ABS resin and the characteristics of PC material. It can adapt to the processing shape requirements of different deformable parts 12 and maintain good formability.

[0048] Optionally, refer to Figure 1 and Figure 2 The deformable member 12 includes a first flexible portion 121 and a second flexible portion 122; one end of the first flexible portion 121 is connected to at least one inner side surface of the frame body 11, and the other end of the first flexible portion 121 is connected to the second flexible portion 122, and the second flexible portion 122 is suitable for contacting the battery cell 2; the extension direction of the first flexible portion 121 intersects with the extension direction of the second flexible portion 122.

[0049] Specifically, if Figure 1 and Figure 2 As shown, the deformable member 12 includes a first flexible portion 121 and a second flexible portion 122. One end of the first flexible portion 121 is connected to the inner side of the frame 11, and the other end is connected to the second flexible portion 122, and the second flexible portion 122 abuts against the battery cell 2. Exemplarily, when the deformable member 12 is connected to the first inner side 112, the first flexible portion 121 extends along the Z direction, and the second flexible portion 122 extends along the X direction or the extension direction and the X direction form a small angle such as 5° or 10°, and the second flexible portion 122 can expand the contact area with the battery cell 2 to improve the abutment reliability. Along the extension direction, the cross-section of the first flexible portion 121 and the second flexible portion 122 is circular, elliptical or quadrilateral, and is usually processed into a circular cross-section due to the characteristics of the injection molding process. And the first flexible portion 121 is a column, and its cross-sectional size is larger than the cross-sectional size of the second flexible portion 122, so that the size of the connection between the deformable member 12 and the inner surface of the frame 11 is larger to ensure its structural strength. The second flexible portion 122, i.e., the top of the deformable member 12, is relatively small and is prone to deformation. The first flexible portion 121 and the second flexible portion 122 are integrally connected, i.e., the deformable member 12 is an integrally formed structure. When the battery cell 2 is loaded into the accommodating space 111, the upper side of the second flexible portion 122 abuts against the bottom of the battery cell 2. When battery cells 2 of different lengths are loaded, the degree of compression of the deformable member 12 is different, and the shape of the deformable member 12 will change accordingly. Figure 6The deformable member 12 on the left side shows that when a shorter battery cell 2 is installed, the deformable member 12 does not deform or deforms slightly. At this time, the dimension of the first flexible portion 121 along the Z direction is a1, and the dimension of the second flexible portion 122 along the X direction is b1. Figure 6 The deformable member 12 on the right reflects that when a longer battery cell 2 is loaded, the deformable member 12 is deformed due to the squeezing force of the battery cell 2, mainly the second flexible portion 122 and the connection between the second flexible portion 122 and the first flexible portion 121. At this time, the dimension of the first flexible portion 121 along the Z direction is a2, and the dimension of the second flexible portion 122 along the X direction is b2, then a1>a2, and b1<b2, that is, the deformable member 12 after being squeezed is short and strong, so as to provide sufficient elastic force to abut the upper part of the battery cell 2 with the third inner side surface 114, so that the battery cell 2 is limited in the frame 11. The specific size of the deformable member 12 is determined according to the assembly requirements. That is, the distance between the top of the second flexible portion 122 and the limiting structure of the third inner side surface 114 needs to be greater than the battery cell length L, but this distance should not be too large to exceed the upper tolerance value that may exist in the battery cell length.

[0050] Optionally, the deformation member 12 is an elastic member.

[0051] Specifically, the deformable member 12 has an elastic force to restore the deformation when subjected to the pressure of the battery cell 2 , that is, the deformable member 12 is an elastic member, including but not limited to a metal spring, an air spring or a rubber spring.

[0052] Optionally, refer to Figure 4 and Figure 5 The deformable member 12 is connected to the inner side surface of the frame 11 so that the battery cell 2 abuts between the deformable member 12 and another inner side surface of the frame opposite to the deformable member 12 .

[0053] Specifically, if Figure 4 and Figure 5 As shown, the deformable member 12 is connected to the first inner side surface 112 or the second inner side surface 113 of the frame 11. When the deformable member 12 is connected to the first inner side surface 112, i.e., the bottom surface of the frame 11, the battery cell 2 abuts between the deformable member 12 and the third inner side surface 114, i.e., the top surface of the frame; when the deformable member 12 is connected to one of the second inner side surfaces 113, the battery cell 2 abuts between the deformable member 12 and the other second inner side surface 113.

[0054] Optionally, refer to Figure 4 and Figure 5 The deformable member 12 is connected to the first inner side surface 112 and / or the second inner side surface 113 of the frame 11; the first inner side surface 112 is opposite to the side of the battery cell 2 provided with the pole ear 21, and the second inner side surface 113 is adjacent to the side of the battery cell 2 provided with the pole ear 21.

[0055] Specifically, the deformable member 12 can be disposed on the first inner side surface 112, the second inner side surface 113, or both the first inner side surface 112 and the second inner side surface 113 of the frame 11. When the deformable member 12 is disposed on the first inner side surface 112 of the frame 11, after the battery cell 2 is installed, the deformable member 12 abuts against the bottom of the battery cell; when the deformable member 12 is disposed on the second inner side surface 113 of the frame 11, after the battery cell 2 is installed, the deformable member 12 abuts against the side of the battery cell. The tab 21 of the battery cell 2 is disposed at the top of the battery cell 2. Figure 4 and Figure 5 As shown, the deformable member 12 of this embodiment is disposed on the first inner side surface 112 of the frame 11. The third inner side surface 114 of the frame 11 is connected with a circuit board 13 for laser welding with the pole ear 21 to form a current path between the battery cell 2 and external electrical equipment. When assembling the battery cell 2, the area of ​​the pad area between the pole ear 21 and the circuit board 13, i.e., the welding portion 131, must meet the requirements to ensure that the welding area has sufficient peel strength to avoid insufficient welding strength and loose connection when the welding area is small, which may cause communication disconnection or failure due to desoldering during the use of the battery. Figure 4 As shown, when the length of the battery cell 2 is close to the lower limit of the design tolerance, the welding area between the tab 21 and the pad of the circuit board 13 can meet the welding requirements under the support of the certain strength of the deformable member 12 itself. Figure 5 As shown, when the length of the battery cell 2 is close to the upper limit of the design tolerance, the extruded deformation piece 12 of the battery cell 2 undergoes elastic deformation. Under the push of the elastic force, the welding area between the tab 21 of the battery cell 2 and the welding pad of the circuit board 13 can also meet the welding requirements.

[0056] Optionally, refer to Figure 2 The surface of the second flexible portion 122 facing away from the first flexible portion 121 is a plane or a curved surface or a surface formed by tangent connection between a plane and a curved surface.

[0057] Specifically, if Figure 2 As shown, the surface of the second flexible portion 122 facing away from the first flexible portion 121, that is, the upper surface of the second flexible portion 122, contacts and abuts against the battery cell 2. The upper surface of the second flexible portion 122 is a plane, or a curved surface, or a surface formed by a plane and a curved surface connected tangent to each other. Such planes have no sharp edges or sharp angles, wherein the plane and the curved surface have a smooth transition at the tangent point, which can avoid scratching the battery cell 2. According to the characteristics of the injection molding process, the upper surface of the second flexible portion 122 of this embodiment is a plane.

[0058] Optionally, refer to Figure 2 The connection between the first flexible portion 121 and the second flexible portion 122 is a rounded transition.

[0059] Specifically, if Figure 2As shown, since the deformable member 12 is made of plastic material, the connection between the first flexible portion 121 and the second flexible portion 122 is a rounded transition, and the connection transition between the two is relatively smooth to disperse stress and avoid excessive stress concentration, thereby improving the overall strength and durability of the deformable member 12.

[0060] Optionally, refer to Figure 1 and Figure 2 The deformable member 12 and the frame body 11 are integrally formed.

[0061] Specifically, if Figure 1 and Figure 2 As shown, the deformable member 12 is integrally connected with the frame 11. The deformable member 12 and the frame 11 are made of the same plastic material, including but not limited to engineering plastics or PC material formed by ABS and PC. During processing, the deformable member 12 and the frame 11 are integrally injection molded by a mold. This molding process has the advantages of high production efficiency, high strength, good dimensional consistency, stable quality, and energy saving and environmental protection.

[0062] Optionally, refer to Figure 1 There are multiple deformable members 12 and they are arranged at intervals, and the multiple deformable members 12 are all used to abut against the battery core 2.

[0063] Specifically, a plurality of deformable members 12 are connected to the first inner side surface 112 of the frame body 11 and / or the second inner side surface 113 of the frame body 11. Figure 1 As shown, in this embodiment, a plurality of deformable members 12 are arranged on the first inner side surface 112 along the X direction to improve the contact strength and force uniformity between the deformable members 12 and the bottom of the battery cell 2. The specific number of deformable members 12 is determined according to the assembly requirements and the battery size, and the number of deformable members 12 contacting each battery cell 2 can be two, three or more.

[0064] Optionally, refer to Figure 1 , Figure 4 and Figure 5 The battery frame assembly further includes a limiting member 14 ; the limiting member 14 is connected to the frame 11 , and the limiting member 14 is arranged opposite to the deformable member 12 .

[0065] Specifically, if Figure 1 , Figure 4 and Figure 5As shown, in this embodiment, the deformable member 12 is arranged on the first inner side surface 112, and the limit member 14 is arranged on the third inner side surface 114. Along the Z direction, the cross-section of the limit member 14 can be circular, elliptical or quadrilateral. In this embodiment, the cross-section of the limit member 14 is circular, and the limit member 14 is cylindrical. The lower end of the limit member 14 is used to limit the top of the battery cell 2, so that during the assembly process, a certain gap is left between the top of the battery cell 2 and the third inner side surface 114 of the frame 11, which is convenient for connecting the circuit board 13. The connection method between the limit member 14 and the frame 11 can be a split connection or an integral molding, which is not limited in this embodiment. At least two limit members 14 can be arranged along the X direction. As Figure 4 As shown, when the length of the battery cell 2 is close to the lower limit of the design tolerance, the bottom of the battery cell 2 is supported and abutted by the deformable member 12, and the top of the battery cell 2 abuts against the limiting member 14. Through the cooperation between the limiting member 14 and the deformable member 12, the battery cell 2 is limited in the accommodating space 111. Figure 5 As shown, when the length dimension of the battery cell 2 is close to the upper limit of the design tolerance, the battery cell 2 squeezes the deformation member 12 to undergo elastic deformation. Along the Z direction, the deformation member 12 provides a force opposite to the limiting member 14. The top of the battery cell 2 abuts against the limiting member 14, and the battery cell 2 is limited in the accommodating space 111.

[0066] The embodiment of the utility model further provides a battery, comprising a battery cell 2 and the battery frame assembly described in any one of the above embodiments; the battery cell 2 is located in the accommodating space 111 , and the battery cell 2 is in contact with the deformable member 12 .

[0067] Optionally, the battery further includes a circuit board 13;

[0068] The battery cell 2 is located in the accommodating space 111 , the circuit board 13 is connected to the frame 11 , a tab 21 is provided on at least one side of the battery cell 2 , the tab 21 is connected to the circuit board 13 , and at least another opposite side of the battery cell 2 abuts against the deformable member 12 .

[0069] Specifically, if Figure 4 and Figure 5 As shown, at least two battery cells 2 may be disposed in the battery accommodation space 111. In this embodiment, three battery cells 2 are disposed as an example. Figure 4 As shown, the length of the battery cell 2 is close to the lower limit of the design tolerance, the deformable member 12 does not undergo elastic deformation or undergoes a small degree of elastic deformation, and under the support of the deformable member 12, the top of the battery cell 2 abuts against the stopper 14, and the welding area between the tab 21 and the pad of the circuit board 13 can meet the welding requirements. Figure 5As shown, when the length dimension of the battery cell 2 is close to the upper limit of the design tolerance, the extruded deformation piece 12 of the battery cell 2 undergoes elastic deformation. Driven by the elastic force, the top of the battery cell 2 abuts against the limiting piece 14, and the welding area between the pole ear 21 and the soldering pad of the circuit board 13 can meet the welding requirements, thereby ensuring that the battery cell 2 is effectively limited in the frame 11 without shaking or displacement, and at the same time ensuring that the welding quality between the pole ear 21 and the soldering pad of the circuit board 13 meets the standards.

[0070] An embodiment of the utility model further provides an electrical device, comprising the battery or battery described in one of the above embodiments.
