Detailed implementation manners

[0030] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0031] Reference will be made below to Figures 1 - 3 describe the cover plate 1 of a battery pack according to an embodiment of the present utility model. The cover plate 1 of the battery pack can be configured into a battery pack structure.

[0032] As Figure 1 and Figure 2 shown, the cover plate 1 of a battery pack according to an embodiment of the present utility model includes: a plate body 10 and a reinforcing member 20. The plate body 10 is the main component of the cover plate 1 of the battery pack, which mainly can play roles of protection, isolation, heat dissipation and electrical insulation. The reinforcing member 20 mainly can play a reinforcing role, which can improve the strength of the structure, thereby can enhance the overall rigidity of the cover plate 1, reduce the stress concentration of the cover plate 1, and improve the safety of the battery pack.

[0033] As Figure 1 and Figure 2 shown, the plate body 10 includes: a main body part 100 and an end edge 101. One end of the end edge 101 is connected to the main body part 100 and is arranged at an angle. The other end of the end edge 101 extends in a direction away from the main body part 100. The reinforcing member 20 is arranged on the inner surface of the plate body 10, and the reinforcing member 20 is connected between the main body part 100 and the end edge 101.

[0034] Among them, the main body part 100 and the end edge 101 are components of the plate body 10. The main body part 100 is the main part of the plate body 10. One end of the end edge 101 is connected to the main body part 100 and is arranged at an angle. At this time, the end edge 101 and the main body part 100 form an integral body, which is convenient for the installation and setting of the plate body 10. In addition, one end of the end edge 101 is arranged at an angle, and at this time, the setting of the end edge 101 is more in line with the actual working conditions. The other end of the end edge 101 extends in a direction away from the main body part 100, and when assembled to the lower cover of the battery pack, the other end of the end edge 101 extends towards the lower cover of the battery pack. In this way, the main body part 100 and the end edge 101 can form a cover-like structure, playing a role of covering and sealing.

[0035] The reinforcing member 20 is arranged on the inner surface of the plate body 10, and the reinforcing member 20 is connected between the main body part 100 and the end edge 101. That is to say, the reinforcing member 20 is arranged between the main body part 100 and the end edge 101. On the one hand, this is convenient for the connection of the reinforcing member 20 and can make the setting of the reinforcing member 20 more firm and stable. On the other hand, the reinforcing member 20 can simultaneously enhance the structural strength of the main body part 100 and the end edge 101. The support strength of the reinforcing member 20 is the best, so that the reinforcing member 20 can better reduce the stress concentration of the cover plate 1 of the battery pack and improve the safety of the battery pack. In addition, the reinforcing member 20 is arranged on the inner surface of the plate body 10, and this setting is more reasonable, which is convenient for the connection between the reinforcing member 20 and the plate body 10, and at the same time, it can also avoid the need to increase extra space when the reinforcing member 20 is arranged on the outer surface of the plate body 10, which is not conducive to the overall setting of the cover plate 1.

[0036] Therefore, by arranging the reinforcing member 20 on the inner surface of the plate body 10 and connecting the reinforcing member 20 between the main body part 100 and the end edge 101, the setting of the reinforcing member 20 can be made more firm and stable, and the support strength of the reinforcing member 20 is the best, which can better reduce the stress concentration of the cover plate 1 of the battery pack and improve the safety of the battery pack. In addition, it can avoid the need to increase extra space when the reinforcing member 20 is arranged on the outer surface of the plate body 10, which is not conducive to the overall setting of the cover plate 1.

[0037] It should be noted that as Figure 2As shown in the figure, the reinforcing member 20 includes a reinforcing main body 202, and the reinforcing main body 202 is inclined. The reinforcing main body 202 is the main part of the reinforcing member 20, and other components can be mainly installed on it. The reinforcing main body 202 is inclined, that is to say, the reinforcing member 20 is inclined between the main body part 100 and the end edge 101. On the one hand, this facilitates the connection of the reinforcing member 20 and can make the setting of the reinforcing member 20 more firm and stable. On the other hand, the reinforcing member 20 can simultaneously improve the structural strength of the main body part 100 and the end edge 101. The supporting strength of the reinforcing member 20 is the best, so that the reinforcing member 20 can better reduce the stress concentration of the cover plate 1 of the battery pack and improve the safety of the battery pack. In addition, the reinforcing member 20 is arranged on the inner surface of the plate body 10. Such a setting is more reasonable, which is convenient for the connection between the reinforcing member 20 and the plate body 10, and at the same time, it can also avoid the need to increase additional space when the reinforcing member 20 is arranged on the outer surface of the plate body 10, which is not conducive to the overall setting of the cover plate 1.

[0038] Specifically, as Figure 3 shown in the figure, an included angle A is formed between the reinforcing main body 202 and the inner surface of the end edge 101, and the value range of A is: 15° ≤ A ≤ 45°. It should be noted that the included angle A between the reinforcing main body 202 and the inner surface of the end edge 101 needs to meet a certain range. Specifically, the included angle A between the reinforcing main body 202 and the inner surface of the end edge 101 cannot be too small, that is, less than 15°. In this case, the included angle A between the reinforcing main body 202 and the inner surface of the end edge 101 is too small, which is not conducive to the arrangement of the reinforcing member 20 and will affect the supporting strength of the reinforcing member 20. At the same time, the included angle A between the reinforcing main body 202 and the inner surface of the end edge 101 cannot be too large, that is, greater than 45°. In this case, the setting of the reinforcing member 20 is unstable, which will also affect the supporting strength of the reinforcing member 20, affect the strengthening effect of the reinforcing member 20 on the inner surface of the plate body 10, and may cause stress concentration of the cover plate 1 of the battery pack, thus causing damage to the battery pack.

[0039] Among them, as Figure 2As shown, first connection parts 200 and second connection parts 201 are provided at both ends of the strengthening body 202. The first connection part 200 is connected to the main body part 100, and the second connection part 201 is connected to the end edge 101. Both the first connection part 200 and the second connection part 201 can play a connecting role. Connect the first connection part 200 to the main body part 100 and the second connection part 201 to the end edge 101. At this time, the strengthening member 20 can be connected to the main body part 100 and the end edge 101 respectively through the first connection part 200 and the second connection part 201, which facilitates the connection between the strengthening member 20 and the main body part 100 and the end edge 101, and can make the setting of the strengthening member 20 more stable and firm. It should be noted that the first connection part 200 and the second connection part 201 can be respectively arranged on the inner surface of the plate body 10 by means of SPR riveting fixation.

[0040] Combined with the above, after adding the strengthening member 20, through mechanical vibration simulation analysis, the stress concentration of the cover plate 1 of the battery pack is reduced by about 40%.

[0041] Optionally, as Figure 2 shown, the first connection part 200 is riveted to the main body part 100, and / or the second connection part 201 is riveted to the end edge 101. At this time, the first connection part 200 and the main body part 100, and the second connection part 201 and the end edge 101 are more in line with the actual working conditions. The connection between the first connection part 200 and the main body part 100, and the second connection part 201 and the end edge 101 is simple in operation, high in connection strength, good in anti-fatigue performance, and detachable. Among them, the rivet 203 can use SPR rivets. The SPR rivets use a self-piercing riveting machine to directly press the SPR rivets into the metal through pressure, without drilling and manual installation of SPR rivets.

[0042] In addition, as Figure 1 and Figure 2 shown, the number of end edges 101 is two. The two end edges 101 are respectively connected to both ends of the main body part 100 in the width direction. Two strengthening members 20 are correspondingly provided and are respectively connected between the main body part 100 and one end edge 101. The strengthening members 20 extend along the length direction of the main body part 100.

[0043] It should be noted that there are two end edges 101, and the two end edges 101 are respectively connected to both ends of the main body 100 in the width direction. At this time, the end edges 101 and the main body 100 form an integral body, which is convenient for the installation and setting of the plate body 10. There are two corresponding reinforcing members 20, and the number of the reinforcing members 20 is also 2. The two reinforcing members 20 are respectively connected between the main body 100 and one end edge 101. The reinforcing members 20 extend along the length direction of the main body 100. On the one hand, this is convenient for the connection of the reinforcing members 20 and can make the setting of the reinforcing members 20 more firm and stable. On the other hand, the reinforcing members 20 can simultaneously improve the structural strength of the main body 100 and the end edge 101. The supporting strength of the reinforcing members 20 is the best, so that the reinforcing members 20 can better reduce the stress concentration of the cover plate 1 of the battery pack and improve the safety of the battery pack. In addition, the reinforcing members 20 are arranged on the inner surface of the plate body 10, and such a setting is more reasonable, which is convenient for the connection between the reinforcing members 20 and the plate body 10, and at the same time, it can also avoid the need to increase extra space when the reinforcing members 20 are arranged on the outer surface of the plate body 10, which is not conducive to the overall setting of the cover plate 1.

[0044] In addition, as Figure 1 and Figure 2 shown, the plate body 10 further includes: a first flanging 102, the first flanging 102 is connected to the other end of the end edge 101 and is arranged at an angle, and the first flanging 102 extends away from the main body 100. The first flanging 102 is a component of the plate body 10 and mainly functions as installation and lifting. Connecting the first flanging 102 to the other end of the end edge 101, at this time, the first flanging 102 and the end edge 101 form an integral body, which is convenient for the installation and arrangement of the plate body 10. The first flanging 102 is arranged at an angle, and at this time, the setting of the first flanging 102 is more in line with the actual working conditions. At the same time, the first flanging 102 extends away from the main body 100, so that the first flanging 102 can be unfolded outward to avoid interference with the main body 100, thus facilitating the installation and lifting of the first flanging 102.

[0045] Of course, as Figure 3As shown, an included angle B is formed between the end edge 101 and the first flanging 102, and the value range of B is: 5° ≤ B ≤ 10°. It should be noted that the included angle B between the end edge 101 and the first flanging 102 needs to meet a certain range. Specifically, the included angle B between the end edge 101 and the first flanging 102 cannot be too small, that is, less than 5°. In this case, the included angle B between the end edge 101 and the first flanging 102 is too small, which is not conducive to the arrangement of the first flanging 102, thus affecting the installation and lifting of the first flanging 102, and also affecting the stamping forming of the cover plate 1. At the same time, the included angle B between the end edge 101 and the first flanging 102 cannot be too large, that is, greater than 10°. In this case, the included angle B between the end edge 101 and the first flanging 102 is too large, which will also affect the stamping forming of the cover plate 1 and may cause damage to the cover plate 1.

[0046] Furthermore, as Figure 1 and Figure 2 shown, a protrusion 103 is further provided on the outer surface of the plate body 10. One end of the protrusion 103 extends to the outer surface of the main body portion 100, and the other end of the protrusion 103 extends along the end edge 101 to the first flanging 102. The protrusion 103 is mainly used to improve the elastic deformation during the stamping of the cover plate 1 of the battery pack. One end of the protrusion 103 extends to the outer surface of the main body portion 100, and the other end of the protrusion 103 extends along the end edge 101 to the first flanging 102. At this time, the protrusion 103, the main body portion 100, and the first flanging 102 form an integral body, which is convenient for the installation and arrangement of the plate body 10. In addition, a protrusion 103 is provided on the outer surface of the plate body 10, and the protrusion 103 can penetrate through the upper surface and the lower surface of the cover plate 1. The design of the position distribution and height of the protrusion 103 can avoid the elastic deformation during the stamping of the cover plate 1, thereby effectively improving the stamping deformation of the cover plate 1.

[0047] Combined with the above, through the simulation analysis after adding the protrusion 103, the deformation of the cover plate 1 of the battery pack has been greatly improved.

[0048] In addition, as Figure 1 and Figure 2 shown, a plurality of lifting lug holes 104 are provided on the first flanging 102, and the plurality of lifting lug holes 104 are arranged at intervals. The protrusion 103 is arranged between two adjacent lifting lug holes 104. The lifting lug holes 104 are mainly used for fixing, shock absorption, noise reduction, and extending the service life of the cover plate 1 of the battery pack. The plurality of lifting lug holes 104 are arranged at intervals. It can be understood that the cover plate 1 is prone to stamping deformation at the positions where the lifting lug holes 104 are provided. By arranging the protrusion 103 between two adjacent lifting lug holes 104, the protrusion 103 can enhance the structural strength at the lifting lug holes 104, thereby avoiding the elastic deformation during the stamping of the cover plate 1 and effectively improving the stamping deformation of the cover plate 1. It should be noted that the setting of the lifting lug holes 104 is based on the vehicle setting.

[0049] It should be noted that, as Figure 1 and Figure 2 shown, the plate body 10 further includes: a second flanging 105, one end of the second flanging 105 is connected to the first flanging 102 and is arranged at an angle, and the other end of the second flanging 105 extends in a direction away from the main body portion 100. The second flanging 105 is a component of the plate body 10, and one end of the second flanging 105 is connected to the first flanging 102. At this time, the first flanging 102 and the second flanging 105 form an integral body, which is convenient for the installation and arrangement of the plate body 10. The second flanging 105 is arranged at an angle, and at this time, the setting of the second flanging 105 is more in line with the actual working conditions and extends in a direction away from the main body portion 100. That is to say, the other end of the second flanging 105 extends downward, so that the second flanging 105 can extend toward the lower housing of the battery pack and block the side surface of the lower housing in the thickness direction of the lower housing, avoiding affecting the adhesion between the cover body 1 and the lower housing during impact.

[0050] In addition, as Figure 2 shown, the cover plate 1 of the battery pack further includes: a high-temperature insulating member 30, and the high-temperature insulating member 30 is arranged on the inner surface of the main body portion 100. The high-temperature insulating member 30 can mainly be used to improve the service life of the battery pack, improve the safety and reliability of the battery pack. The high-temperature insulating member 30 is arranged on the inner surface of the main body portion 100, which can play a certain insulating effect between the battery cells and the plate body 10, reducing the risk of arcing in the battery pack under high-temperature conditions, thereby improving the safety of the battery pack. It should be noted that the high-temperature insulating member 30 can be adhesively bonded to the inner surface of the main body portion 100 through glue.

[0051] Optionally, as Figure 2 shown, the high-temperature insulating member 30 is a composite material member. The composite material member has good high-temperature insulating performance, which can play a certain insulating effect between the battery cells and the plate body 10, reducing the risk of arcing in the battery pack under high-temperature conditions, thereby improving the safety of the battery pack.
