It will be appreciated that the manner of connection of the tabs 30 to the cells 20 is not limited, so as to be able to transfer force to each other. In some embodiments, the tab 30 is welded to the battery cell 20, so that the connection reliability of the tab 30 and the battery cell 20 is good, and the tab is not easy to loosen in moving and vibrating environments.

An insulator 40 is provided between the tab 30 and the case 10. The insulating member 40 has high insulation properties, and can insulate the tab 30 from the case 10.

The stress of the box 10 can be transferred to the pole column 21 of the battery monomer 20 and supported by the pole column 21 of the battery monomer 20, so that the strength of the pole column 21 is effectively utilized, and the overall strength of the battery is improved.

For example, referring to fig. 1 and 3, the battery includes a bead 50, the bead 50 being disposed between the shoulder 22 of the battery cell 20 and the case 10. The insulating member 40 connects the beads 50 to the battery cells 20 and the case 10, respectively. The insulator 40 is capable of transmitting force between the battery cells 20, the bead 50 and the case 10.

Namely, the bead 50 is connected with the battery cell 20 through the insulation 40, and the bead 50 is connected with the case 10 through the insulation. It will be appreciated that an insulator 40 is provided between the bead 50 and the battery cell 20, and that an insulator 40 is also provided between the bead 50 and the case 10.

The insulator 40 is capable of transmitting force between the battery cells 20, the bead 50 and the case 10. That is, the case 10 is capable of transmitting force to the battery cell 20 through the insulating member 40 and the bead 50. The stress of the battery cell 20 can be transmitted to the case 10 through the pressing bar 50 and the insulating member 40, so that the passage for mutual force transmission between the battery cell 20 and the case 10 is further increased, and the overall structural strength is improved.

The case 10 can press the beads 50 against the battery cells 20, thereby limiting the vibration of the battery cells 20. When the pressing bar 50 is connected to the adjacent two battery cells 20, the relative displacement of the adjacent two battery cells 20 in the up-down direction can be reduced, so that the overall stability of the battery is improved.

It will be appreciated that referring to fig. 1 and 3, in some embodiments, the beads 50 are aligned in the length direction. The length direction is a direction perpendicular to the two narrow sidewalls of the battery cell 20. I.e. in the length direction in fig. 1. The width of the two beads 50, which are located on both sides in the length direction, is smaller than the width of the remaining beads 50. The remaining beads 50 can be pressed against two adjacent battery cells 20 stacked in the length direction, and the two beads 50 at both sides in the length direction are respectively pressed against the corresponding one of the battery cells 20 at both sides stacked in the length direction.

The pressing part 52 presses two adjacent battery cells 20 in the length direction to restrict the relative displacement of the two adjacent battery cells 20.

The material of the bead 50 is not limited, and may be plastic or rubber, for example.

For example, referring to fig. 1 and 3, the battery includes a first plate 60, and the first plate 60 is disposed between the tab 30 and the case 10. The insulator 40 connects the tab 30 and the first plate 60.

The first plate 60 is located in the receiving chamber 10a of the case 10 and contacts the inner wall of the case 10. The first plate 60 serves to support the case 10 to improve the overall strength of the battery.

The first plate 60 is disposed between the tab 30 and the case 10, and the insulating member 40 connects the tab 30 and the first plate 60. It will be appreciated that the insulating member 40 is capable of insulating the tab 30 from the first plate 60, while allowing force to be transferred between the tab 30 and the case 10. In this way, the case 10 can transmit the stress to the tabs 30 through the first plate 60 and the insulator 40, so that the case 10 is supported. When the bar 30 is stressed on the side close to the pole 21, the stress can be transmitted to the box 10 through the insulating piece 40 and the first plate 60, so that the bar 30 is supported by the box 10.

It should be noted that, because there may be an uneven area on the inner wall of the case 10, a portion of the uneven area may be located opposite to the post 21 or the tab 30 of the battery cell 20, which affects the force transmission effect. Through setting up first plate 60, can make each battery monomer 20 all pass through first plate 60 and pass power to box 10, and then improve holistic intensity.

During assembly, each pressing bar 50 can be respectively positioned through each groove 60a, and the displacement of the pressing bar 50 along the width direction can be limited by the grooves 60a, so that the connection reliability of the pressing bar 50 and the first plate 60 in a vibration scene is improved.

Wherein the groove 60a extends in the same direction as the bead 50. The width of the bottom surface of the groove 60a is the same as the width of the side of the pressing bar 50 facing the groove 60a or slightly larger than the width of the side of the pressing bar 50 facing the groove 60a, so that the side of the pressing bar 50 facing the groove 60a can be attached to the bottom surface of the groove 60 a.

Wherein the opening of the groove 60a of the first plate 60 is in a flared structure in cross section to guide the positioning bead 50. At least one bead 50 is disposed within each groove 60 a. When a plurality of beads 50 are disposed in the groove 60a, each bead 50 is disposed in sequence along the length direction of the groove 60 a.

Wherein the depth of the groove 60a is smaller than the height of the bead 50. When the bead 50 is disposed within the groove 60a, a portion of the bead 50 can extend out of the groove 60a.

Illustratively, an insulator 40 (not shown in fig. 1) is disposed between the end of the battery cell 20 facing away from the pole 21 and the housing 10, the insulator 40 being capable of transmitting force between the battery cell 20 and the housing 10.

It will be appreciated that the housing 10 is capable of transmitting a force to the cells 20 through the insulator 40 such that the housing 10 is supported. The stress of the battery cell 20 can be transmitted to the case 10 through the insulating member 40, so that the battery cell 20 is supported by the case 10. When the one end that battery monomer 20 deviates from utmost point post 21 can pass power through insulating part 40 and box 10, and the one end that battery monomer 20 has utmost point post 21 can pass power through tab 30, insulating part 40 and box 10, the atress of box 10 one side can pass through battery monomer 20 and transmit to the opposite side of box 10, and the opposite side of box 10 can play the effect of support to further promoted holistic intensity.

Illustratively, the battery includes a second plate disposed between the end of the battery cell 20 facing away from the post 21 and the housing 10. An insulating member 40 (not shown in fig. 1) is provided between the end of the battery cell 20 facing away from the pole 21 and the second plate, and the insulating member 40 connects the battery cell 20 and the second plate.

The second plate is positioned in the receiving chamber 10a of the case 10 and contacts the inner wall of the case 10, and the second plate serves to support the case 10 to improve the overall strength of the battery.

The second plate is disposed between the end of the battery cell 20 facing away from the post 21 and the case 10. The insulating member 40 connects the battery cell 20 and the second plate member. Wherein the insulating member 40 is capable of transferring force between the battery cell 20 and the second plate member. In this way, the case 10 is able to transmit the force to the second plate and to the end of the battery cell 20 facing away from the post 21 through the second plate and the insulator 40, so that the case 10 is supported. When the battery cell 20 is stressed, it can be transferred to the first plate 60 and the case 10 through the insulating member 40, so that the battery cell 20 is supported by the case 10 and the first plate 60.

It should be noted that, due to the uneven surface may exist on the inner wall of the case 10, a portion of the uneven structure may be located opposite to the end of the battery cell 20 facing away from the post 21. Through setting up the second plate, can make each battery monomer 20 all pass through the second plate and pass power to box 10, and then improve holistic intensity.

Illustratively, the case 10 includes an upper cover 11 and a lower cover 12. The upper cover 11 is located at an end of the battery cell 20 facing away from the post 21. The bottom cover 12 is positioned at one end of the post 21 of the battery cell 20. An insulator 40 is provided between the tab 30 and the bottom cover 12.

It will be appreciated that the upper cover 11 and the lower cover 12 enclose the receiving chamber 10a. In some embodiments, the upper cover 11 is above the bottom cover 12 after the battery is assembled to the vehicle.

The upper cover 11 is located at one end of the battery cell 20 facing away from the pole 21, and the bottom cover 12 is located at one end of the pole 21 of the battery cell 20, i.e. the battery cell 20 is arranged upside down, and one end of the pole 21 of the battery cell 20 faces downwards.

An insulator 40 is provided between the tab 30 and the bottom cover 12, it being understood that the insulator 40 is capable of transferring force between the tab 30 and the bottom cover 12. That is, the bottom cover 12 can transmit the force to the tabs 30 and the poles 21 of the battery cells 20 through the insulating member 40, so that the case 10 is supported.

It should be noted that, since the pole 21 of the battery cell 20 needs to be kept free, the impact-receiving capability of one side of the bottom cover 12 is reduced. While the battery bottom cover 12 of some vehicles is close to the ground, its ability to withstand impacts directly affects the safety of the battery. In the above embodiment, by providing the insulating member 40 between the tab 30 and the bottom cover 12, the entire strength of the battery can be improved by insulating the tab 30 from the bottom cover 12 by the insulating member 40 while transmitting the impact applied to the bottom cover 12 to the posts 21 of the battery cell 20.

It will be appreciated that the structure of the insulator 40 is not limited. In some embodiments, the insulating member 40 is an insulating sheet, and may be made of plastic or rubber.

In still other embodiments, the insulating member 40 is an insulating glue layer. The insulating adhesive layer has the function of bonding and fixing, so that the connection stability of the bonded parts in vibration and moving scenes is improved. Taking the insulating member 40 between the tab 30 and the case 10 as an example: when the first plate 60 is disposed between the tab 30 and the case 10, the insulating adhesive layer is disposed between the tab 30 and the first plate 60, and between the first plate 60 and the case 10, so as to bond and fix the tab 30, the first plate 60 and the case 10, thereby improving the connection stability of the three under the vibration environment.

In some embodiments, the insulating glue layer 40 is formed by glue dispensing or glue injection.

In some embodiments, the battery may not only serve as an operating power source for the vehicle, but also as a driving power source for the vehicle, instead of or in part instead of fuel oil or natural gas, to provide driving power for the vehicle.

The battery is mounted on the vehicle. It is to be understood that the orientation of the pole 21 of the battery cell 20 is not limited, and the pole 21 of the battery cell 20 may be disposed toward any side in the vehicle height direction, the pole 21 of the battery cell 20 may be disposed toward any side in the vehicle width direction, or the pole 21 of the battery cell 20 may be disposed toward any side in the vehicle length direction.

In some embodiments, the posts 21 of the battery cells 20 are disposed downward. Because the insulating piece 40 is arranged between the tab 30 and the box body 10, the insulating piece 40 can transfer force between the tab 30 and the box body 10, so that the overall stability of the battery structure is improved.

It will be appreciated that when the poles 21 of the battery cells 20 are disposed downward, the space between the bottom cover 12 of the case 10 and the poles 21 is reduced by the clearance design of the poles 21, and the bottom cover 21 is less resistant to impact and deformation. By providing the insulating member 40 between the tab 30 and the bottom cover 12, the entire strength of the battery can be improved by insulating the tab 30 from the bottom cover 12 through the insulating member 40 while transmitting the impact of the bottom cover 12 to the posts 21 of the battery cell 20.
