[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] Reference below Figure 1-Figure 5 A battery assembly 100 according to an embodiment of the present invention is described.

[0032] like Figure 1-Figure 5 As shown, the battery assembly 100 according to the embodiment of the present invention includes: a battery body 10 , a first fixing member 20 and a second fixing member 30 .

[0033] The battery body 10 can be installed on an electrical device, for example, the battery body 10 can be installed on a vehicle, and the battery body 10 has a connecting portion 11. As some embodiments of the present application, the connecting portion 11 can be located at one end of the battery body 10 close to the electrical device, for example Figure 2 and Figure 3As shown, when the battery body 10 is mounted on a sheet metal component 50 of a vehicle, the connection portion 11 may be located at one end of the battery body 10 close to the sheet metal component 50 .

[0034] The first fixing member 20 can move along the height direction of the battery assembly 100, wherein the height direction can be Figure 2 In the Z direction shown in the figure, as some embodiments of the present application, the first fixing member 20 can be fixed to the electrical equipment, for example Figure 2 and Figure 3 As shown, the first fixing member 20 can be fixed to the sheet metal member 50 of the vehicle, or the first fixing member 20 can also be fixedly connected to the battery body 10 or other components.

[0035] As some embodiments of the present application, Figure 2 and Figure 3 As shown, a bolt 41 can be passed through the first fixing member 20 to fix the first fixing member 20 to the electrical device, and the nut 402 of the bolt 41 abuts against the first fixing member 20, and by screwing the bolt 41, the first fixing member 20 can be driven to move in the height direction of the battery assembly 100. Alternatively, a nail can be passed through the first fixing member 20 to fix the first fixing member 20 to the electrical device, and the head of the nail abuts against the first fixing member 20, and by hitting the nail, the first fixing member 20 can be driven to move downward in the height direction of the battery assembly 100.

[0036] The second fixing member 30 is disposed between the first fixing member 20 and the battery body 10, and a portion of the second fixing member 30 is in contact with the connecting portion 11. As some embodiments of the present application, along the height direction of the battery assembly 100 (i.e. Figure 2 The second fixing member 30 may be located above the connecting portion 11 and contact the connecting portion 11, the first fixing member 20 may have a first mating surface 21, the second fixing member 30 may have a second mating surface 31, the second mating surface 31 may be mated with the first mating surface 21, and at least one of the first mating surface 21 and the second mating surface 31 may have an angle with the height direction.

[0037] As some embodiments of the present application, the first mating surface 21 is parallel to the height direction, and the second mating surface 31 has an angle with the height direction. As some embodiments of the present application, the second mating surface 31 is parallel to the height direction, and the first mating surface 21 has an angle with the height direction. As some embodiments of the present application, both the first mating surface 21 and the second mating surface 31 have an angle with the height direction.

[0038] It should be explained that the angle between the first mating surface 21 and the height direction can be understood as the angle between the first mating surface 21 and the plane where the height direction is located, that is, the first mating surface 21 is not parallel to the plane where the height direction is located, and the same applies to the second mating surface 31.

[0039] The first fixing member 20 moves close to the second fixing member 30 to drive the second fixing member 30 to move close to the battery body 10. Figure 2 and Figure 3 As shown, since the second mating surface 31 is mated with the first mating surface 21, and at least one of the first mating surface 21 and the second mating surface 31 has an angle with the height direction, when the first fixing member 20 is controlled to be along the height direction of the battery assembly 100 (i.e. Figure 2 When the first fixing member 20 is moved in the Z direction as shown, and the first fixing member 20 is moved close to the second fixing member 30 (i.e., moved downward), the first fixing member 20 can drive the second fixing member 30 to move horizontally and close to the battery body 10. When the second fixing member 30 is moved horizontally and close to the battery body 10 until the end of the second fixing member 30 abuts against the battery body 10, the first fixing member 20 continues to be moved close to the second fixing member 30. The second fixing member 30 can press the connecting portion 11 to fix the battery body 10 to other components (such as the sheet metal part 50 of the vehicle). This installation method does not require frequent adjustment of the position of the second fixing member 30, and the operation is simple and convenient.

[0040] Moreover, the vertical movement of the first fixing member 20 can be converted into the horizontal movement of the second fixing member 30 by the second matching surface 31 matching with the first matching surface 21 .

[0041] It is understandable that in the present application, the first fixing member 20 is floating, and before the second fixing member 30 is driven into place, the first fixing member 20 will not contact with the sheet metal member 50 and other components of the vehicle, which can realize dynamic adjustment of the clamping gap, that is, the movement stroke of the first fixing member 20 can be controlled according to the specific shape, position and other parameters of the connecting portion 11 and the first fixing member 20, and the first fixing member 20 and the second fixing member 30 can be made applicable to a variety of battery bodies 10, which can improve the versatility of the first fixing member 20 and the second fixing member 30. After the second fixing member 30 is driven into place, the first fixing member 20 may contact with the sheet metal member 50 and other components of the vehicle, or may not contact with the sheet metal member 50 and other components of the vehicle.

[0042] Therefore, by setting the first fixing member 20 and making the first fixing member 20 and the second fixing member 30 have matching first matching surfaces 21 and second matching surfaces 31 respectively, the movement of the first fixing member 20 close to the second fixing member 30 in the height direction can drive the second fixing member 30 to move close to the battery body 10, so as to press the connecting part 11 through the second fixing member 30 to fix the battery body 10 to other components (such as a vehicle). This installation method does not require frequent adjustment of the position of the second fixing member 30, is simple and convenient to operate, and is conducive to improving installation efficiency.

[0043] As some embodiments of the present application, Figure 2 and Figure 3 As shown, the first fixing member 20 can be configured as a hollow member, which is beneficial to saving materials.

[0044] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, along the height direction of the battery assembly 100 (i.e. Figure 2 The Z direction shown in FIG. 1 ) and the direction in which the first fixing member 20 approaches the second fixing member 30 (i.e., along the Figure 2 In other words, along the height direction of the battery assembly 100 (i.e., the height of the battery assembly 100 is the same as the height of the battery assembly 100). Figure 2 The Z direction shown in FIG. 1 ) and the direction in which the first fixing member 20 approaches the second fixing member 30 (i.e., along the Figure 2 The first mating surface 21 may extend in a direction away from the battery body 10, or the second mating surface 31 may extend in a direction away from the battery body 10, or both the first mating surface 21 and the second mating surface 31 may extend in a direction away from the battery body 10. This arrangement can reliably drive the second fixing member 30 to move through the first fixing member 20.

[0045] Please refer to Figure 2 As shown, at least one of the first mating surface 21 and the second mating surface 31 may extend obliquely from the upper left to the lower right.

[0046] As some embodiments of the present application, the first mating surface 21 can extend obliquely from the upper left to the lower right, and the second mating surface 31 can be in the height direction (i.e. Figure 2 A plane parallel to the Z direction (shown).

[0047] As some embodiments of the present application, the second mating surface 31 can extend obliquely from the upper left to the lower right, and the first mating surface 21 can be in the height direction (i.e. Figure 2 A plane parallel to the Z direction (shown).

[0048] As some examples of this application, please refer to Figure 2 and Figure 3 As shown, the first mating surface 21 and the second mating surface 31 can both extend obliquely from the upper left to the lower right.

[0049] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the first mating surface 21 and the second mating surface 31 can both extend in a direction away from the battery body 10. Specifically, along the height direction of the battery assembly 100 (i.e. Figure 2 The Z direction shown in FIG. 1 ) and the direction in which the first fixing member 20 approaches the second fixing member 30 (i.e., along the Figure 2 In the top-to-bottom direction shown in the figure, the first mating surface 21 and the second mating surface 31 both extend in a direction away from the battery body 10, and, as some embodiments of the present application, the first mating surface 21 and the second mating surface 31 have the same inclination angle. Such a setting can more reliably drive the second fixing member 30 to move through the first fixing member 20, and can make the first mating surface 21 and the second mating surface 31 fit smoothly.

[0050] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the second fixing member 30 may have a third mating surface 35 opposite to the second mating surface 31, and the connecting portion 11 may have a fourth mating surface 12 mating with the third mating surface 35. Specifically, the second fixing member 30 has a second mating surface 31 and a third mating surface 35, and along the thickness direction of the second fixing member 30, the second mating surface 31 and the third mating surface 35 are respectively located on two opposite surfaces of the second fixing member 30, wherein the second mating surface 31 faces the first fixing member 20, and the third mating surface 35 faces the connecting portion 11.

[0051] The connecting portion 11 may have a fourth mating surface 12, and the fourth mating surface 12 may be mated with the third mating surface 35. Figure 2 The Z direction shown in FIG. 1 ) and the direction in which the first fixing member 20 approaches the second fixing member 30 (i.e., along the Figure 2 In other words, along the height direction of the battery assembly 100 (i.e., the height of the battery assembly 100 is 100 m), at least one of the third mating surface 35 and the fourth mating surface 12 may extend in a direction away from the battery body 10. Figure 2 The Z direction shown in FIG. 1 ) and the direction in which the first fixing member 20 approaches the second fixing member 30 (i.e., along the Figure 2 The third mating surface 35 may extend in a direction away from the battery body 10, or the fourth mating surface 12 may extend in a direction away from the battery body 10, or both the third mating surface 35 and the fourth mating surface 12 may extend in a direction away from the battery body 10.

[0052] Please refer to Figure 2 As shown, at least one of the third mating surface 35 and the fourth mating surface 12 may extend obliquely from the upper left to the lower right.

[0053] As some embodiments of the present application, the third mating surface 35 can extend obliquely from the upper left to the lower right, and the fourth mating surface 12 can be in the height direction (i.e. Figure 2 A plane parallel to the Z direction (shown).

[0054] As some embodiments of the present application, the fourth mating surface 12 can extend obliquely from the upper left to the lower right, and the third mating surface 35 can be in the height direction (i.e. Figure 2 A plane parallel to the Z direction (shown).

[0055] As some examples of this application, please refer to Figure 2 and Figure 3 As shown, the third mating surface 35 and the fourth mating surface 12 can both extend obliquely from the upper left to the lower right.

[0056] As some embodiments of the present application, Figure 2 and Figure 3 As shown, the third mating surface 35 and the fourth mating surface 12 can both extend in a direction away from the battery body 10. Specifically, along the height direction of the battery assembly 100 (i.e. Figure 2 The Z direction shown in FIG. 1 ) and the direction in which the first fixing member 20 approaches the second fixing member 30 (i.e., along the Figure 2 The third mating surface 35 and the fourth mating surface 12 both extend in a direction away from the battery body 10, and, as some embodiments of the present application, the third mating surface 35 and the fourth mating surface 12 have the same inclination angle. This arrangement can make the second fixing member 30 move smoothly along the horizontal direction close to the battery body 10, and can make the contact area between the second fixing member 30 and the connecting portion 11 large, so that the connecting portion 11 can be reliably pressed.

[0057] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the second fixing member 30 may include a first plate portion 32 and a second plate portion 33 that are connected. The first plate portion 32 may have a third mating surface 35 , and the second plate portion 33 may have a second mating surface 31 .

[0058] Specifically, the surface of the first plate portion 32 facing the connecting portion 11 may be the third mating surface 35, and the surface of the second plate portion 33 facing the first fixing member 20 may be the second mating surface 31. In some embodiments of the present application, the first plate portion 32 and the second plate portion 33 may be an integrally formed part, and such a configuration may reduce the difficulty of manufacturing the second fixing member 30 and improve the manufacturing efficiency of the second fixing member 30.

[0059] As some embodiments of the present application, the first plate portion 32 and the second plate portion 33 may be separate parts. This arrangement allows different first plate portions 32 and second plate portions 33 to be manufactured as needed, which is conducive to improving the commonality of the first plate portion 32 and / or the second plate portion 33.

[0060] As some embodiments of the present application, the inclination angles of the first plate portion 32 and the second plate portion 33 can be the same, that is, the angle between the first plate portion 32 and the horizontal plane is equal to the angle between the second plate portion 33 and the horizontal plane. Such a setting can reduce the manufacturing difficulty of the second fixing member 30 and improve the manufacturing efficiency of the second fixing member 30.

[0061] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the first plate portion 32 and the second plate portion 33 may have an angle, that is, the inclination angle of the first plate portion 32 and the inclination angle of the second plate portion 33 may be different. This arrangement allows the first plate portion 32 to be designed according to the inclination angle of the fourth mating surface 12, and the second plate portion 33 to be designed according to the inclination angle of the first mating surface 21, which is conducive to improving the compatibility of the second fixing member 30 and the connecting portion 11, and the second fixing member 30 and the first fixing member 20. In addition, this arrangement is conducive to saving space (for this, please refer to Figure 2 and Figure 3 Understanding, for Figure 2 and Figure 3 In the illustrated embodiment, if the second plate portion 33 is rotated counterclockwise to an angle parallel to the first plate portion 32 , the space occupied by the first fixing member 20 will be increased.

[0062] As some embodiments of the present application, Figure 3 As shown, the second fixing member 30 may further include a third plate portion 34, one end of the third plate portion 34 may be connected to one end of the second plate portion 33 away from the first plate portion 32, the other end of the third plate portion 34 may extend in a direction away from the battery body 10, and the third plate portion 34 may be attached to the sheet metal part 50 of the vehicle. It should be explained that if the speed of driving the first fixing member 20 downward is too fast, there is a slight possibility that the second fixing member 30 may rotate as a whole. By setting the third plate portion 34, the third plate portion 34 may be limited with the sheet metal part 50 of the vehicle to limit the rotation of the second fixing member 30, thereby reducing the difficulty of installation.

[0063] In some embodiments of the present invention, Figure 4 As shown, the third mating surface 35 may have a protrusion 351 protruding toward the connecting portion 11. In short, the third mating surface 35 may be an uneven surface. Such a setting can increase the pressure between the second fixing member 30 and the connecting portion 11, which is beneficial to increasing the clamping force.

[0064] As some embodiments of the present application, Figure 5 As shown, the third matching surface 35 may also be a plane. Such a configuration can reduce the difficulty of manufacturing the second fixing member 30 , which is beneficial to improving the manufacturing efficiency of the second fixing member 30 .

[0065] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the battery assembly 100 may further include: a driving member 40, the driving member 40 may abut against the first fixing member 20, and the driving member 40 may be moved along the height direction of the battery assembly 100 (ie Figure 2 The first fixing member 20 is driven to move (in the Z direction shown).

[0066] As some embodiments of the present application, Figure 2 and Figure 3 As shown, the driving member 40 may be configured as a bolt 41, and the bolt 41 may include a screw 401 and a nut 402. The first fixing member 20 may be fixed to the sheet metal member 50 of the vehicle. Specifically, the side wall of the first fixing member 20 away from the sheet metal member 50 may have a first mounting through hole 22, and the screw 401 may be inserted into the first mounting through hole 22 and screwed to the sheet metal member 50. As some embodiments of the present application, the first fixing member 20 may have a side wall close to the sheet metal member 50, or the first fixing member 20 may not have a side wall close to the sheet metal member 50 (i.e., the first fixing member 20 is open toward the sheet metal member 50). If the first fixing member 20 has a side wall close to the sheet metal member 50, the side wall may have a second mounting through hole 23, and the second mounting through hole 23 corresponds to the first mounting through hole 22. The screw 401 may be inserted into the first mounting through hole 22 and the second mounting through hole 23 and screwed to the sheet metal member 50.

[0067] The nut 402 of the bolt 41 can abut against the side wall of the first fixing member 20 away from the sheet metal member 50 . By screwing the bolt 41 , the first fixing member 20 can be driven to move along the height direction of the battery assembly 100 .

[0068] like Figure 2 and Figure 3 As shown, the battery assembly 100 may further include: a nut 42 that cooperates with the bolt 41. The nut 42 may be arranged on a side of the sheet metal part 50 away from the first fixing part 20. By setting the nut 42, there is no need to set an internal thread in the hole of the sheet metal part 50, which is conducive to reducing the production difficulty of the sheet metal part 50.

[0069] As some embodiments of the present application, the driving member 40 can be constructed as a nail, which can include a nail rod and a nail head. The first fixing member 20 can be fixed to the sheet metal member 50 of the vehicle. Specifically, the nail can pass through the first fixing member 20 and be connected to the sheet metal member 50. The nail head can abut against the side wall of the first fixing member 20 away from the sheet metal member 50. By hammering the nail, the first fixing member 20 can be driven to move along the height direction of the battery assembly 100.

[0070] By providing the driving member 40, the first fixing member 20 can be driven to move, and by connecting the driving member 40 to the sheet metal member 50 of the vehicle, the driving member 40 has the function of driving the first fixing member 20 to move and assembling the first fixing member 20 to the sheet metal member 50 of the vehicle.

[0071] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, along the first direction, both ends of the second fixing member 30 may have a limiting portion 331 protruding toward the first fixing member 20, and at least a portion of the first fixing member 20 may be located between the two limiting portions 331, wherein the first direction is perpendicular to the height direction and the moving direction of the second fixing member 30.

[0072] As some embodiments of the present application, Figure 2 As shown, the height direction can be Figure 2 In the Z direction shown, the moving direction of the second fixing member 30 can be Figure 2 The first direction may be a Y direction perpendicular to the Z direction and the X direction, for example Figure 4 As some embodiments of the present application, the limiting portion 331 may be integrally formed with the second fixing member 30 . As some embodiments of the present application, the limiting portion 331 may be connected to the second plate portion 33 .

[0073] The two limiting portions 331 can define a limiting space 332, and at least a portion of the first fixing member 20 can be located in the limiting space 332, that is, at least a portion of the first fixing member 20 can be located between the two limiting portions 331. It should be noted that the first fixing member 20 can only be moved along the limiting space 332. Figure 2 The Z-direction movement shown is achieved by positioning at least a portion of the first fixing member 20 between the two limiting portions 331. When the second fixing member 30 is subjected to a force in the first direction, the limiting portion 331 can contact the first fixing member 20, and the first fixing member 20 can limit the limiting portion 331 to limit the second fixing member 30, thereby preventing the second fixing member 30 from moving in the first direction, and improving the installation efficiency of the battery body 10.

[0074] As some embodiments of the present application, Figure 3 As shown, the battery assembly 100 may further include: a guide plate 60, which may be disposed on a side of the first fixing member 20 away from the second fixing member 30, the guide plate 60 may be connected to the sheet metal member 50 of the vehicle, the surface of the guide plate 60 facing the first fixing member 20 may be parallel to the surface of the first fixing member 20 facing the guide plate 60, and the surface of the guide plate 60 facing the first fixing member 20 may be guided and matched with the surface of the first fixing member 20 facing the guide plate 60, when the first fixing member 20 is moved along Figure 2When the Z direction shown moves downward, the guide plate 60 can play a guiding role to ensure that the moving direction of the first fixing member 20 is accurate.
