Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of batteries, in particular to a shell of a battery module, the battery module and a vehicle. BACKGROUND

[0002] In some battery modules in the related art, an electrode protection cover and a frame are installed together through buckling, that is, the electrode protection cover is provided with a resilient arm, the frame is provided with a groove, and the resilient arm is deformed and then rebounds to be embedded in the groove, so as to realize the connection between the electrode protection cover and the frame.

[0003] However, the deformation and rebound of the resilient arm are prone to cause the breakage of the resilient arm, resulting in poor reliability of the installation of the electrode protection cover. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a shell of a battery module, the battery module and a vehicle, which can improve the reliability of the installation of the output electrode protection cover.

[0005] In a first aspect, a shell of a battery module is provided, which includes a side plate and an output electrode protection cover. The output electrode protection cover is arranged opposite to an output electrode of the battery module. One of the output electrode protection cover and the side plate is formed with a mounting groove, and the other is formed with a mounting portion matched with the mounting groove. The mounting groove can slide along the mounting portion, and the groove wall of the mounting groove clamps the mounting portion. One end of the mounting groove is formed with a mounting opening, and the mounting portion can extend into the mounting groove through the mounting opening.

[0006] By enabling the mounting portion to extend into the mounting groove through the mounting opening and enabling the mounting groove to slide along the mounting portion, the mounting portion does not need to be deformed and then rebounded in the height direction of the mounting groove during the process of entering the mounting groove. Instead, the mounting portion only needs to enter the mounting groove through the mounting opening and slide along the extension direction of the mounting groove relative to the mounting groove. In this way, the mounting portion is not prone to breakage, which is conducive to improving the reliability of the installation between the side plate and the output electrode protection cover. After the mounting portion enters the mounting groove, the groove wall of the mounting groove clamps the mounting portion, which can maintain the relative position between the output electrode protection cover and the side plate, so as to stably install the output electrode protection cover and the side plate. Therefore, the shell of the battery module provided by the present application has stable installation between the output electrode protection cover and the side plate, and the mounting portion is not prone to breakage, which can improve the reliability of the installation of the output electrode protection cover.

[0007] In combination with the first aspect, in some possible implementation manners, the shell of the battery module further includes an end plate. In a first direction, an end surface of a first end of the end plate is arranged opposite to the output electrode protection cover. The first direction, the thickness direction of the side plate and the thickness direction of the end plate are perpendicular to each other. One of the mounting portion and the mounting groove is arranged on the surface of the side plate close to one side of the battery module.

[0008] By arranging one of the mounting portion and the mounting groove on the surface of the side plate close to the side of the battery module, the space in the battery module is fully utilized, which is conducive to improving the compactness of the structure and reducing the volume of the battery module.

[0009] In some possible implementation manners, in combination with the first aspect and the foregoing implementation manners, the mounting groove is located on one side of the end plate along the first direction.

[0010] In this way, the part of the output pole protection cover opposite to the end face of the first end of the end plate is mounted on the side plate through the mounting groove and the mounting portion, so that the output pole protection cover and the end plate enclose a relatively stable accommodation space, and the accommodation space accommodates the output pole, which can better protect the output pole. Moreover, the mounting groove is located on one side of the end plate along the first direction, which is conducive to reducing the length of the output pole protection cover in the thickness direction of the end plate and improving the compactness of the structure.

[0011] In some possible implementation manners, in combination with the first aspect and the foregoing implementation manners, the mounting groove extends along the thickness direction of the end plate.

[0012] The side plate extends in the thickness direction of the end plate, and the mounting groove extends along the thickness direction of the end plate, so that the length of the side plate in the thickness direction of the end plate and in the first direction is fully utilized, which is conducive to improving the compactness of the structure and reducing the length of the side plate in the thickness direction of the side plate and in the first direction.

[0013] In some possible implementation manners, in combination with the first aspect and the foregoing implementation manners, the surface of the output pole protection cover away from the end plate is concavely provided with a strip-shaped groove, and the extension direction of the strip-shaped groove and the extension direction of the mounting groove form an included angle, and the included angle is greater than or equal to 60° and less than or equal to 90°.

[0014] By forming the strip-shaped groove on the surface of the output pole protection cover away from the end plate, the friction between the hand and the surface of the output pole protection cover away from the end plate can be increased, the extension direction of the strip-shaped groove and the extension direction of the mounting groove form an included angle, and the included angle is greater than or equal to 60° and less than or equal to 90°, so that the friction in the extension direction of the mounting groove can be significantly improved, and the process of pushing the output pole protection cover in the extension direction of the mounting groove can be more labor-saving, the groove wall of the mounting groove can be conveniently slid relative to the output pole protection cover, and the installation of the output pole protection cover and the side plate is realized.

[0015] In some possible implementation manners, in combination with the first aspect and the foregoing implementation manners, the output pole protection cover includes a main plate body, and the thickness direction of the main plate body is parallel to the first direction; and along the thickness direction of the end plate, an edge of one end of the main plate body away from the battery module is provided with a breakable flange, and the breakable flange extends toward the end plate.

[0016] By making the output pole protective cover include a main plate body and a breakable flange, the surface of one side of the output pole along the first direction and the surface of one side along the thickness direction of the end plate can be protected by the output pole protective cover, which is beneficial to the reliability of the battery module. In the case where the output pole needs to be connected with external equipment, the breakable flange can be broken to remove the shielding of the output pole along the thickness direction of the end plate, so that the output pole can be smoothly connected with the external equipment.

[0017] With reference to the first aspect and the above implementation manner, in some possible implementation manners, the output pole protective cover includes a main plate body, and the thickness direction of the main plate body is parallel to the first direction; the main plate body includes a first part and a second part, and the first part and the second part are arranged along the thickness direction of the side plate; along the first direction, the spacing between the second part and the end plate is greater than the spacing between the first part and the end plate.

[0018] By making the main plate body include the first part and the second part arranged along the thickness direction of the side plate, and along the first direction, the spacing between the second part and the end plate is greater than the spacing between the first part and the end plate, the first part and the second part can enclose accommodation spaces with different lengths along the first direction with the end plate respectively, so as to accommodate various devices, which is beneficial to improve the adaptability of the output pole protective cover.

[0019] With reference to the first aspect and the above implementation manner, in some possible implementation manners, the number of the breakable flanges is at least two, and the at least two breakable flanges are arranged at intervals along the thickness direction of the side plate.

[0020] By arranging the at least two breakable flanges at intervals, the at least two breakable flanges can be broken respectively, so that the process of breaking the breakable flange is more labor-saving. Moreover, the at least two breakable flanges can be respectively arranged corresponding to the at least two output poles, which is beneficial to improve the protection effect of the output pole protective cover.

[0021] With reference to the first aspect and the above implementation manner, in some possible implementation manners, one end of the breakable flange close to the main plate body is provided with a first hole, and the depth direction of the first hole is parallel to the thickness direction of the end plate.

[0022] By providing the breakable flange with the first hole at one end close to the main plate body, the strength of the one end of the breakable flange close to the main plate body is reduced, so that the breakable flange can be conveniently broken from this position by a person, and the process of breaking the breakable flange is more labor-saving.

[0023] With reference to the first aspect and the above implementation manner, in some possible implementation manners, the first end of the main plate body is provided with a second hole, the second hole is located at the breakable flange, and the depth direction of the second hole is parallel to the first direction.

[0024] By setting the first end of the main plate body with the second hole, that is, setting the end close to the breakable flange of the main plate body with the second hole, the strength at the boundary between the main plate body and the breakable flange is reduced, and a person can conveniently separate the breakable flange from the main plate body, so that the breakable flange is broken more labor-saving.

[0025] In combination with the first aspect and the above implementation manners, in some possible implementation manners, the number of the side plates is two, the two side plates are oppositely arranged, and the mounting groove and the mounting portion are arranged between the output pole protection cover and each side plate.

[0058] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The shell 1 provided by the embodiments of the present application further comprises an output pole protection cover 12, which is arranged opposite to the output pole 4 of the battery module. One of the output pole protection cover 12 and the side plate 1 is formed with a mounting groove 12111, and the other is formed with a mounting portion 11 matched with the mounting groove 12111. The mounting groove 12111 can slide along the mounting portion 11, and the groove wall of the mounting groove 12111 clamps the mounting portion 11. One end of the mounting groove 12111 is formed with a mounting opening 121111, and the mounting portion 11 can extend into the mounting groove 12111 through the mounting opening 121111.

[0059] By enabling the mounting portion 11 to extend into the mounting groove 12111 through the mounting opening 121111, the mounting groove 12111 can slide along the mounting portion 11, so that during the process of the mounting portion 11 entering the mounting groove 12111, the mounting portion 11 only needs to pass through the mounting opening 121111 and slide along the extension direction of the mounting groove 12111 relative to the mounting groove 12111, without the need to deform first and then rebound in the height direction of the mounting groove 12111. In this way, the mounting portion 11 is not easy to break, which is beneficial to improve the reliability of the installation between the side plate 1 and the output pole protection cover 12. After the mounting portion 11 enters the mounting groove 12111, the groove wall of the mounting groove 12111 clamps the mounting portion 11, which can maintain the relative position between the output pole protection cover 12 and the side plate 1, so as to stably install the output pole protection cover 12 and the side plate 1. Therefore, the shell 1 of the battery module provided by the present application has the advantages that the installation between the output pole protection cover 12 and the side plate 1 is stable, and the mounting portion 11 is not easy to break, which can improve the reliability of the installation of the output pole protection cover 12.

[0060] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 It can be understood that, in the embodiments of the present application, the mounting groove 12111 can be formed on the output pole protection cover 12, and the mounting portion 11 can be formed on the side plate 1; or the mounting portion 11 can be formed on the output pole protection cover 12, and the mounting groove 12111 can be formed on the side plate 1.

[0061] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 It can be understood that, in the embodiment of the present application, the mounting groove 12111 can slide along the mounting portion 11, and the direction in which the mounting groove 12111 slides along the mounting portion 11 is the extension direction of the mounting groove 12111. It should be noted that the extension direction of the mounting groove 12111 is perpendicular to the depth direction of the mounting groove 12111.

[0062] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 It can be understood that, in the embodiment of the present application, one end of the mounting groove 12111 penetrates the side plate 1 along the extension direction of the mounting groove 12111, and the mounting opening 121111 is formed.

[0063] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 It can be understood that, in the embodiment of the present application, the groove wall of the mounting groove 12111 clamps the mounting portion 11, that is, the side surfaces on both sides of the mounting portion 11 are in abutment with the groove wall of the mounting groove 12111 along at least one direction perpendicular to the extension direction of the mounting groove 12111. For example, in some embodiments of the present application, the side surfaces on both sides of the mounting portion 11 are in abutment with the groove wall of the mounting groove 12111 along the width direction of the mounting groove 12111, that is, the groove wall of the mounting groove 12111 clamps the mounting portion 11 along the width direction of the mounting groove 12111. It should be noted that the extension direction of the mounting groove 12111, the width direction of the mounting groove 12111 and the depth direction of the mounting groove 12111 are perpendicular to each other.

[0064] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments of the present application, the mounting portion 11 is in interference fit with the mounting groove 12111. In this way, the stability of the mounting of the mounting portion 11 and the mounting groove 12111 is improved. Along the extension direction of the mounting groove 12111, the output pole protection cover 12 and the side plate 1 are limited by the friction force between the groove wall of the mounting groove 12111 and the mounting portion 11, and the mounting of the output pole protection cover 12 on the side plate 1 is more stable.

[0065] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6In some embodiments of the present application, the length of the mounting portion 11 is the same as the length of the mounting groove 12111 along the extension direction of the mounting groove 12111. In this way, the mounting portion 11 and the mounting groove 12111 have a large matching length, which is beneficial to improve the stability of the connection between the mounting portion 11 and the mounting groove 12111.

[0066] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 It can be understood that, in the process of mounting the output pole protection cover 12 on the side plate 1 in the embodiments of the present application, the mounting portion 11 is first made to enter the mounting groove 12111 through the mounting opening 121111, and then the mounting portion 11 and the mounting groove 12111 continue to slide relative to each other. The direction in which the mounting groove 12111 slides relative to the mounting portion 11 is the opposite direction of the direction in which the opening is oriented, and the direction in which the mounting portion 11 slides relative to the mounting groove 12111 is the direction in which the opening is oriented. After the mounting portion 11 and the mounting groove 12111 slide a target distance, the output pole protection cover 12 is in a target position relative to the side plate 1, and the output pole protection cover 12 is opposite to the output pole 4 in this position, thereby achieving the mounting of the output pole protection cover 12 on the side plate 1.

[0067] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments of the present application, the mounting groove 12111 is a half-through groove, that is, the end of the mounting groove 12111 away from the mounting opening 121111 has a stop portion 121112, and the stop portion 121112 and the mounting portion 11 limit each other along the extension direction of the mounting groove 12111. In this structure, the stop portion 121112 can limit the distance of the relative sliding of the mounting portion 11 and the mounting groove 12111, so that the mounting portion 11 and the mounting groove 12111 are difficult to continue to slide after sliding a target distance, which is beneficial to keep the output pole protection cover 12 in the target position relative to the side plate 1.

[0068] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments of the present application, the mounting portion 11 and the groove wall of the mounting groove 12111 abut along the depth direction of the mounting groove 12111. In this way, the side plate 1 can limit the output pole protection cover 12 along the depth direction of the mounting groove 12111, which is beneficial to improve the reliability of the mounting of the output pole protection cover 12.

[0069] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6Generally, the output pole 4 includes a positive output pole 4 and a negative output pole 4. In the embodiments of the present application, the positive output pole 4 and the negative output pole 4 can be arranged opposite to two output pole protection covers 12 respectively, or the positive output pole 4 and the negative output pole 4 can be arranged opposite to the same output pole protection cover 12.

[0070] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments of the present application, the output pole protection cover 12 is provided with a positive pole mark 12112 at the positive output pole 4 and a negative pole mark 12112 at the negative output pole 4. In this way, it is convenient for personnel to determine the positions of the positive output pole 4 and the negative output pole 4. In some embodiments of the present application, along the first direction, the positive pole mark 12112 is arranged on the surface of the side of the output pole protection cover 12 away from the end plate 13, and along the first direction, the negative pole mark 12112 is arranged on the surface of the side of the output pole protection cover 12 away from the end plate 13. In this way, the positive pole mark 12112 and the negative pole mark 12112 are not easily blocked by other components of the battery module, and it is convenient for personnel to observe.

By arranging one of the mounting portion 11 and the mounting groove 12111 on the surface of the side of the side plate 1 close to the inside of the battery module, the space inside the battery module is fully utilized, which is conducive to improving the compactness of the structure and reducing the volume of the battery module.

[0073] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6Generally, in some embodiments of the present application, the output pole 4 is arranged on the end face of the first end of the end plate 13 opposite the output pole protection cover 12, so that the end face of the first end of the end plate 13 and the output pole protection cover 12 enclose a containing space for containing the output pole 4, the output pole 4 can be better protected, and the reliability of the battery module is improved.

[0074] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 Generally, in some embodiments of the present application, the first direction is the vertical direction, the output pole 4 is arranged on the upper end face of the end plate 13, and the output pole protection cover 12 is arranged opposite the upper end face of the end plate 13.
