Referring to fig. 1 to 4 in combination, fig. 1 is a schematic front view of a battery case according to an embodiment of the present utility model, fig. 2 is a schematic left view of the battery case in fig. 1, fig. 3 is a schematic top view of the battery case in fig. 1, and fig. 4 is a schematic axial view of the battery case in fig. 1. The battery case 100 is used to assemble a battery module. The battery case 100 includes a case body 10 and a case cover 20 detachably coupled to the case body 10. The case 10 includes a case bottom, a plurality of case walls surrounding the case bottom, and a plurality of case walls and the case bottom form an accommodating space for accommodating the battery module.

Optionally, the case cover 20 is opposite to the case bottom, and the case cover 20 may be fixed on the case wall by a connector such as a screw 21, so as to detachably connect the case cover 20 with the case body 10, and perform a sealing function on the battery case 100, so as to protect the battery module in the battery case 100.

The battery box 100 further comprises hoisting members 30 fixed on two sides of the box body 10, the hoisting members 30 comprise fixing portions 31 and first extending portions 32 fixedly connected with each other, the fixing portions 31 are fixedly connected with the box body 10, and the first extending portions 32 extend from the fixing portions 31 in a direction away from the box body 10. The hanging member 30 is configured to be engaged with an auxiliary hanging member to carry the battery case 100. The fixed connection mode comprises threaded connection, key connection, pin connection, welding and the like. Naturally, in order to facilitate the disassembly and replacement of the lifting member 30, the lifting member 30 may be fixedly connected to the case 10 by screw threads. In order to improve the overall structural stability of the hoisting member 30, the fixed connection manner between the parts of the hoisting member 30 may be selected to be welded, or the parts of the hoisting member 30 may be integrally formed.

Thus, through set up hoist and mount component 30 on the box 10 of battery case 100 to conveniently adopt the mode transport battery case 100 of hoist and mount, thereby need not to adopt artifical transport, avoided adopting the potential safety hazard that artifical transport exists, and improved the efficiency of transport.

It will be appreciated that, in order to fix the battery box 100 and transmit power of the battery module, the battery box 100 further includes a fixing bracket 40 disposed on the box body 10 and a plurality of groups of charge and discharge ports 50, and the fixing bracket 40 is fixedly connected with the box body 10. Specifically, the fixing bracket 40 is fixed to a wall of the case 10, and is located at a side of the wall near the bottom. The charge and discharge port 50 is used for charging and discharging the battery module. Naturally, in order to avoid damage caused by overcurrent or short circuit of the battery module, the battery box 100 is further provided with an overcurrent protector 60, such as a fuse or other protection device.

In one embodiment, referring to fig. 1 and 2, the hanging members 30 are located at opposite sides of the case 10, and at least one hanging member 30 is disposed at each side. Optionally, at least one of the hoisting members 30 is provided on each side, and the number of hoisting members 30 on each side is the same, to improve stability at hoisting. Opposite sides of the case 10 refer to opposite case walls of the case 10.

It should be noted that, for convenience of description, the opposite sides of the case 10 are defined as a first side and a second side, at least two lifting members are disposed on each of the first side and the second side, and the number of the lifting members 30 on the first side is equal to the number of the lifting members on the second side. Located between the first side and the second side are a third side and a fourth side, which are also opposite, wherein the first side, the second side, the third side and the fourth side each refer to one wall of the case 10. In addition, the case 10 of the present utility model is not limited to having four sides, and the case 10 of the present utility model may include more or less sides.

Alternatively, the hanging members 30 may be located at a side of the case 10 adjacent to the case cover 20, for example, each hanging member 30 may be fixed at three-quarters of the height of the case 10, and the fixed heights of the hanging members 30 may be the same. I.e. each of the lifting members 30 is three times the distance from the bottom of the box than each of the lifting members 30 is from the cover 20. In this way, by fixing the lifting member 30 at a position close to the case cover 20, when the battery case 100 is lifted, the center of gravity of the lifting can be moved downward, so that the battery case 100 is prevented from tilting, and the lifting stability can be further improved.

Meanwhile, the lifting members 30 on one side of the case 10 are opposite to the lifting members 30 on the opposite side, that is, the orthographic projection of the lifting members 30 on the first side of the case 10 on the second side coincides with the lifting members 30 on the second side, so that the lifting members 30 on the first side and the lifting members 30 on the second side are symmetrically arranged, and thus, when the battery case 100 is lifted, the forces born by the lifting members 30 can be balanced, and the battery case 100 is prevented from being inclined due to uneven stress on the lifting members 30, thereby further improving the lifting stability.

Optionally, as shown in fig. 3, the hanging member 30, the fixing bracket 40 and the overcurrent protector 60 are located on the same side of the case 10, so as to reduce the space occupied by the battery case 100 after installation.

Specifically, the fixing brackets 40 are located at opposite sides of the case 10, the hanging members 30 are also located at the same opposite sides of the case 10, and the overcurrent protector 60 is located between the hanging members 30 and the fixing brackets 40 on one of the opposite sides of the case 10. Specifically, the fixing bracket 40 and the hanging member 30 are located on the first side and the second side of the case 10, at least two hanging members 30 and at least two fixing brackets 40 are disposed on the first side, at least two hanging members 30 and at least two fixing brackets 40 are also disposed on the second side, and two overcurrent protectors 60 are also disposed between the hanging members 30 and the fixing brackets 40 on the second side. In this way, the hanging member 30, the fixing bracket 40 and the overcurrent protector 60 are all concentrated on the first side and the second side of the case 10, and occupy only a part of the side surface of the case 10, so that after the battery case 100 is fixed on a device, the space occupied by the battery case 100 in excess of the device can be reduced.

Alternatively, as shown in fig. 4, a protruding portion 11 is provided on a side of the case body 10 adjacent to the case cover 20, and the case cover 20 is detachably connected to the protruding portion 11. In this way, when the screw 21 is used to detachably connect the cover 20 to the protrusion 11, there is enough space on the protrusion 11 for the screw 21 to be inserted, thereby improving the connection stability of the cover 20 to the case 10. Meanwhile, the protruding portion 11 can also protect other parts of the box 10 and the hoisting member 30 and other parts arranged on the box 10. In addition, some warning marks may be provided on the case cover 20 to play a role in reminding and warning.

In one embodiment, with continued reference to fig. 1 to 4, the hoisting member 30 further includes a first limiting portion 33, the first limiting portion 33 is fixedly connected to the first extending portion 32, and the extending direction of the first limiting portion 33 is the same as that of the fixing portion 31. Optionally, the first limiting portion 33 is configured to cooperate with the first extending portion 32 to limit the auxiliary lifting element.

In one embodiment, the hoisting member 30 further includes a second extending portion 34 and a second limiting portion 35, where the second extending portion 34 is fixedly connected with the first extending portion 32 and extends from the end of the first extending portion 32 in a direction away from the case 10, the second limiting portion 35 is fixedly connected with the second extending portion 34, and the extending direction of the second limiting portion 35 is the same as that of the first limiting portion 33. The second limiting portion 35 and the first limiting portion 33 are configured to limit the auxiliary hanging member.

Alternatively, in the direction along which the second extending portion 34 extends, the distance between the first limiting portion 33 and the fixing portion 31 is equal to the protruding length of the protruding portion 11 protruding from the case 10, for example, the distance between the first limiting portion 33 and the fixing portion 31 is equal to or slightly smaller than the protruding length of the protruding portion 11 protruding from the case 10, so as to avoid interference between the auxiliary hanging member, which is limited between the first limiting portion 33 and the second limiting portion 35, and the protruding portion 11 and/or the case cover 20.

The second extending portion 34 is provided with a first opening 341, the second limiting portion 35 is provided with a second opening 351, the second opening 351 extends along the extending direction of the second limiting portion 35, and the second opening 351 penetrates through the second limiting portion 35 and part of the second extending portion 34, so that the second opening 351 is communicated with the first opening 341.

In one embodiment, in order to facilitate the lifting of the battery case 100 and improve the stability of the lifting, the battery case 100 further includes an auxiliary lifting member 70 adapted to the lifting member 30. Specifically, referring to fig. 1 to 9 in combination, fig. 5 is a schematic front view of an auxiliary lifting member according to an embodiment of the present utility model, fig. 6 is a schematic cross-sectional structure of the auxiliary lifting member in fig. 5, and fig. 7 to 9 are schematic structural views of the auxiliary lifting member in fig. 5 at different angles after being assembled on a lifting member.

Referring to fig. 5 and 6, the auxiliary hanging member 70 includes a base 71 and a hanging portion 72 fixedly connected, wherein a hanging portion 73 is disposed at a distal end of the hanging portion 72 extending in a direction away from the base 71, and the hanging portion 73 is in a ring shape. The auxiliary hoist 70 may be assembled in the hoist member 30 such that the hoist apparatus may hoist the battery case 100 through the auxiliary hoist 70. Alternatively, the base 71 may be in a block shape, and the base 71, the hanging portion 72, and the hanging portion 73 may be integrally formed.

Specifically, referring to fig. 7, 8 and 9, the auxiliary lifting member 70 may be movably assembled in the lifting member 30 through the first opening 341 and the second opening 351, so that the base 71 is limited in a space surrounded by the first limiting portion 33, the second extending portion 34 and the second limiting portion 35, and the auxiliary lifting member 70 may only move in a small space through the common limitation of the first limiting portion 33 and the second limiting portion 35, so as to avoid a large swing between the auxiliary lifting member 70 and the lifting member 30, thereby improving the lifting stability.

Specifically, the hanging portion 72 of the auxiliary hanging member 70 may slide into the first opening 341 from the second opening 351 and slide up and down in the first opening 341, so that the base 71 slides into a space enclosed by the first limiting portion 33, the second extending portion 34, and the second limiting portion 35. Wherein the vertical orthographic projection of the first opening 341 is located outside the vertical orthographic projection of the case cover 20 to avoid interference between the auxiliary hanging member 70 and the case cover 20 after the auxiliary hanging member 70 is assembled to the hanging member 30. That is, the length of the protrusion of the lifting member 30 relative to the case 10 is greater than the length of the protrusion 11 of the case 10, so that the protrusion 11 can also protect the case cover 20, further preventing the auxiliary lifting member 70 from interfering with the case cover 20, and preventing the case cover 20 from being worn.

Alternatively, the size of the first opening 341 is larger than the size of the second opening 351 in the width direction of the second extension 34, wherein the width direction of the second extension 34 is perpendicular to the extension direction of the second extension 34. The size of the first opening 341 refers to the length of the first opening 341 in the width direction of the second extension 34, and the size of the second opening 351 refers to the length of the second opening 351 in the width direction of the second extension 34. By making the size of the first opening 341 larger than the size of the second opening 351, when the auxiliary hoist 70 is assembled to the hoist member 30, the hanging portion 72 of the auxiliary hoist 70 does not slide out of the second opening 351 due to the blocking limit of the first opening 341 to the auxiliary hoist 70 even if the battery case 100 is shaken during the hoist of the battery case 100, thereby further improving the hoist stability.

Alternatively, in the extending direction of the second limiting portion 35, the length of the second limiting portion 35 is smaller than that of the first limiting portion 33, so as to facilitate the assembly and disassembly of the auxiliary hanging member 70. The extending directions of the second limiting portion 35 and the first limiting portion 33 are the same, and the extending directions are substantially parallel to the wall of the case 10 and perpendicular to the extending directions of the first extending portion 32 and the second extending portion 34, and the extending directions of the first extending portion 32 and the second extending portion 34 are the same.

Optionally, in the extending direction of the first limiting portion 33, the length of the first limiting portion 33 is smaller than that of the fixing portion 31, so that the overall stability of the hoisting member 30 can be improved under the limiting effect of the auxiliary hoisting member 70, and the stability of the fixed connection between the hoisting member 30 and the box 10 is further improved.

In one embodiment, the base 71 is provided with a groove 711 on a side facing the hanging portion 72, the groove 711 is provided with an elastic member 74, and the elastic member 74 is embedded in the groove 711. The height of the elastic member 74 is greater than the depth of the groove 711 so that the elastic member 74 extends beyond the surface of the base 71 facing the hanging portion 72. Thus, when the auxiliary hanging member 70 is assembled to the hanging member 30, the portion of the elastic member 74 beyond the base 71 abuts against the hanging member 30, and more specifically, the elastic member 74 abuts against the second extending portions 34 on both sides of the first opening 341.

The material of the elastic member 74 includes an elastic material such as silicone rubber, etc., and the elastic member 74 has elasticity due to good elasticity of the elastic material such as silicone rubber, etc. Thus, when the elastic member 74 is pressed, elastic deformation occurs, and the elastic deformation can absorb part of the pressing force between the auxiliary hanging member 70 and the hanging member 30, so as to play a role of shock absorption. Thereby reducing friction between the auxiliary hanging member 70 and the hanging member 30 and avoiding damage to the external appearance of the battery case 100.

Alternatively, the number of the grooves 711 is two, and two of the grooves 711 are located on opposite sides of the hanging portion 72. More specifically, the distances from the two grooves 711 to the hanging portion 72 are equal to balance the pressing forces applied to the bases 71 at both sides of the hanging portion 72, so as to ensure that the stress at each of the hanging members 30 is balanced during the hanging of the battery case 100, and avoid the battery case 100 from tilting.

It should be noted that the structure of the auxiliary hanging member 70 of the present utility model is not limited thereto, and the battery case 100 of the present utility model may not include the auxiliary hanging member 70, that is, the auxiliary hanging member 70 is not a part of the battery case 100, and the auxiliary hanging member 70 is a separate body, so that the auxiliary hanging member 70 is not configured for each battery case 100, thereby saving costs. In addition, the lifting member 30 of the present utility model may be adapted to other types of temporary auxiliary lifting members, such as a simpler construction of the lifting hook 80, the lifting rope 90, etc. In this manner, when the auxiliary hoist 70 is not disposed on the battery case 100, the hook 80 or the hoist rope 90 or the like may be used as a temporary auxiliary hoist to be engaged with the hoist member 30 to hoist the battery case 100, thereby increasing the adaptability of the hoist member 30 on the battery case 100.

Specifically, in one embodiment, please refer to fig. 1 to 10 in combination, fig. 10 is a schematic diagram showing the fitting of the lifting member 30 and the lifting hook 80 of the battery box 100 according to an embodiment of the present utility model. As shown in fig. 10, one end of the hook 80 is bent into a hook shape, when the battery box 100 is hoisted, the bent end of the hook 80 is embedded into the first opening 341 of the hoisting member 30, and the first limiting portion 33, the second limiting portion 35 and the first opening 341 together perform a limiting function on the hook 80, thereby increasing the adaptability of the hoisting member 30 on the battery box 100.

In an embodiment, please refer to fig. 1 to 11 in combination, fig. 11 is a schematic diagram showing the fitting of the hanging member 30 and the hanging rope 90 of the battery box 100 according to an embodiment of the utility model. As shown in fig. 11, when the battery box 100 is hoisted, the lifting rope 90 is inserted into the space enclosed by the first limiting portion 33, the second extending portion 34 and the second limiting portion 35, and is hoisted by taking the second extending portion 34 as a supporting point, so that the adaptability of the hoisting member 30 on the battery box 100 is increased.

In one embodiment, the embodiment of the utility model further provides a power battery system, which comprises a battery box, a battery module and a wire harness for connecting the battery module and the battery box, wherein the battery box comprises the battery box of one of the previous embodiments. The wire harness is connected with the charging and discharging ports on the battery module and the battery box, and can also be connected with the overcurrent protector on the battery module and the battery box.

As can be seen from the above embodiments:

in the battery box and the power battery system provided by the embodiment of the utility model, the battery box comprises a box body and hoisting members fixed on two sides of the box body, the hoisting members comprise fixing parts and first extending parts which are fixedly connected, the fixing parts are fixedly connected with the box body, and the first extending parts extend from the fixing parts to a direction far away from the box body.
