The embodiment of the application provides a schematic structure diagram of a battery box. As shown in fig. 1 and 2, the battery case includes: the fixed box 1 is provided with an accommodating cavity 11, the fixed frame 2 is fixed in the accommodating cavity 11, and the accommodating cavity 11 is divided into a first cavity 111 surrounded by the fixed frame 2 and a second cavity 112 located on the periphery of the first cavity 111.

As shown in fig. 1, the fixing box 1 includes a box body 12 and a box cover 13, wherein the top end of the box body 12 is open, and the box cover 13 is fixed on the top end of the box body 12 to define a closed accommodating cavity 11, and the accommodating cavity 11 is generally used for accommodating the battery module 3 and the matched electrical module.

In the embodiment of the present application, the accommodating chamber 11 is divided into the first chamber 111 and the second chamber 112 by the fixing frame 2, so that the battery module 3 is fixed in the first chamber 111 surrounded by the fixing frame 2, and the mating electrical module is fixed in the second chamber 112. So, not only be convenient for battery module 3 fixed to improve battery module 3's fixed efficiency, can also realize battery module 3 and electric module's independent setting, when guaranteeing the aesthetic property, can avoid battery module 3 and electric module's mutual interference, thereby improve the security of battery box.

The electrical module includes a battery management system, a contactor, a protector, a connection terminal, an explosion-proof valve, a circuit board, and the like, which is not specifically limited in this embodiment.

As shown in fig. 2, the fixing frame 2 includes a surrounding barrier 21 and a baffle 22, the surrounding barrier 21 is fixed to the accommodating cavity 11, a side surface of the surrounding barrier 21 is open, the baffle 22 is installed on an opening side of the surrounding barrier 21, the baffle divides the accommodating cavity 11 into a first chamber 111 surrounded by the surrounding barrier 21 and the baffle 22, and a second chamber 112 located at the periphery of the first chamber 111, and an installation depth of the baffle 22 on the opening side of the surrounding barrier 21 is adjustable.

So, to treating fixed battery module 3, can be according to the shared space of battery module 3, the position of adjustment baffle 22, and then adjust the size of first cavity 111, guarantee simultaneously that baffle 22 can support and lean on battery module 3, guarantee the steadiness that battery module 3 is fixed.

In the embodiment of the application, when the battery modules 3 are fixed in the battery box, the number of the battery modules 3 can be adjusted as required, and then the size in the first cavity 111 is adjusted according to the space occupied by the battery modules 3 after the number adjustment; or the size of the battery module 3 is adjusted as needed, and then the size of the first chamber 111 is adjusted according to the space occupied by the battery module 3 after the size adjustment. So, through the size of nimble adjustment first cavity 111 for the battery box of this application can be applicable to different dimensions, the fixed of the battery module 3 of different quantity, with the universal performance of effectively improving the battery box.

In some embodiments, as shown in fig. 3, the enclosure 21 includes a side plate 211, and two end plates 212 located on the same side of the side plate 211 and facing each other to form a U-shaped structure with one side open. In this way, after the baffle 22 is installed on the opening side of the enclosure 21, the battery module 3 to be fixed can be four-sided limited, thereby improving the stability of fixing the battery module 3.

Wherein the width of the baffle 22 in a direction horizontally parallel to the side plates 211 is less than or equal to the distance between the two end plates 212. In this way, the baffle 22 can be mounted on the open side of the enclosure 21 in a manner parallel to the side plates 211 to ensure that the first chamber 111 enclosed by the fixed frame 2 is a rectangular chamber. The width dimension of the baffle 22 in the direction horizontally parallel to the side plate 211.

The side plate 211 and the two end plates 212 may be an integral structure, or may be a split structure, that is, the side plate 211 and the two end plates 212 are independent of each other.

When the side plate 211 and the two end plates 212 are of an integrated structure, at least one of the side plate 211 and the two end plates 212 may be fixed to the bottom or the side wall of the fixed box 1; when the side plate 211 and the two end plates 212 are in a split structure, if the side plate 211 and the two end plates 212 are fixed in advance, at least one of the side plate 211 and the two end plates 212 may be fixed to the bottom or the side wall of the fixed box 1; if the side plate 211 and the two end plates 212 are not fixed in advance, both the side plate 211 and the two end plates 212 are fixed to the bottom or the side wall of the fixed box 1.

In the case of the baffle 22 being adjustable in position on the opening side of the enclosure 21, the baffle 22 is fixed to the enclosure 21 and the fixing position on the enclosure 21 is adjustable, or the baffle 22 is fixed to the bottom of the stationary box 1 and the fixing position on the bottom of the stationary box 1 is adjustable. Next, two fixing positions of the shutter 22 will be explained separately.

In the case that the baffle 22 is fixed on the enclosure 21, in combination with the structure of the enclosure 21 described above, in some embodiments, as shown in fig. 4, two end portions of the baffle 22 in the direction parallel to the horizontal direction of the side plate 211 are respectively provided with a first flanging 221, the first flanging 221 has a plurality of first fixing holes 222 distributed at intervals in the depth direction of the fixing box 1, and the end plate 212 has a plurality of sets of second fixing holes 2121 distributed at intervals side by side in the direction perpendicular to the side plate 211; each set of the second fixing holes 2121 includes a plurality of second fixing holes 2121 distributed at intervals in the depth direction of the fixing box 1, and the plurality of second fixing holes 2121 correspond to the plurality of first fixing holes 222 one to one.

When the baffle 22 is mounted on the opening side of the enclosure 21, the mounting depth of the baffle 22 on the opening side of the enclosure 21 is adjusted by adjusting the connection of the plurality of first fixing holes 222 and the different sets of second fixing holes 2121.

As such, when the baffle 22 is fixed to the outermost set of second fixing holes 2121 of the end plate 212 (the set of second fixing holes 2121 farthest from the side plate 211), the space of the first chamber 111 is maximized at this time; when the blocking plate 22 is fixed to the group of second fixing holes 2121 of the innermost side of the end plate 212 (the group of second fixing holes 2121 closest to the side plate 211), the space of the first chamber 111 is minimized at this time. Specifically, when the battery module 3 is fixed, the baffle plate 22 and the end plate 212 are selectively fixed through the set of second fixing holes 2121 on the end plate 212 according to the space occupied by the battery module 3 to be fixed, so as to flexibly adjust the size of the first chamber 111.

One of the first fixing hole 222 and the second fixing hole 2121 may be a through hole, and the other may be a threaded hole, and at this time, the retaining plate 22 and the end plate 212 may be fixed by using a fixing screw; alternatively, the first fixing hole 222 and the second fixing hole 2121 may be through holes, and the baffle plate 22 and the end plate 212 may be fixed by fixing bolts.

Alternatively, the plurality of sets of second fixing holes 2121 are uniformly distributed in the direction perpendicular to the side plate 211, and the distance between two adjacent sets of second fixing holes 2121 is equal to the size of one battery module 3 in the direction perpendicular to the side plate 211. In this way, when one row of the battery modules 3 (one group of the battery modules 3 parallel to the side plate 211) is decreased or increased with respect to the battery modules 3 fixed in the first chamber 111, the blocking plate 22 only needs to be moved to a position corresponding to the adjacent group of the second fixing holes 2121 in a direction approaching to the side plate 211 or separating from the side plate 211.

Of course, the distance between the adjacent two sets of second fixing holes 2121 may also be slightly greater than the dimension of one battery module 3 in the direction perpendicular to the side plates 211. In order to ensure that the baffle 22 can completely abut against the battery modules 3 facing the outside, spacers or the like may be provided between two adjacent battery modules 3 in the direction perpendicular to the side plates 211. Such as a cushion.

Alternatively, as shown in fig. 4, the end plate 212 further has a plurality of slide ways 2122 extending in a direction perpendicular to the side plate 211, and a slide way 2122 communicates with a plurality of second fixing holes 2121 distributed in the thickness direction of the side plate 211.

Here, the thickness direction of the side plate 211 is a direction perpendicular to the side plate 211 in the present embodiment. For the fixing members (for example, fixing bolts) for fixing the baffle 22 and the end plate 212, when the position of the baffle 22 is adjusted, the fixing members only need to be slid into the slide ways 2122, and then adjusted synchronously with the baffle 22, and after the position of the second fixing hole 2121 of the target group is adjusted, the fixing members are moved to the second fixing holes 2121. Thus, the situation that the fixing pieces are detached from the baffle plate 22 and the end plate 212 is avoided, the fixing pieces are prevented from being lost, and the fixing efficiency of the fixing pieces on the baffle plate 22 and the end plate 212 is improved.

In the case that the baffle plate 22 is fixed to the bottom of the fixed box 1, in some embodiments, as shown in fig. 5, the baffle plate 22 has a second flanging 223 along the depth direction of the fixed box 1 near the edge of the bottom of the fixed box 1, the second flanging 223 has a plurality of third fixing holes 224 distributed at intervals along the direction parallel to the horizontal direction of the side plate 211, the bottom of the fixed box 1 has a plurality of sets of fourth fixing holes 231 (not shown) distributed at intervals side by side along the direction perpendicular to the horizontal direction of the side plate 211, each set of fourth fixing holes 231 includes a plurality of fourth fixing holes 231 distributed at intervals along the direction parallel to the horizontal direction of the side plate 211, and the plurality of fourth fixing holes 231 corresponds to the plurality of third fixing holes 224 one to one.

When the baffle 22 is mounted on the opening side of the enclosure 21, the mounting depth of the baffle 22 on the opening side of the enclosure 21 is adjusted by adjusting the connection of the plurality of third fixing holes 224 and the different sets of fourth fixing holes 231.

In this way, when the baffle 22 is fixed to the outermost set of the fourth fixing holes 231 (the farthest set of the fourth fixing holes 231 from the side plate 211) at the bottom of the fixing box 1, the space of the first chamber 111 is the largest at this time; when the baffle 22 is fixed to the innermost set of the fourth fixing holes 231 of the end plate 212 (the set of the fourth fixing holes 231 closest to the side plate 211), the space of the first chamber 111 is minimized at this time. When fixing the battery module 3, the baffle plate 22 and the fixing box 1 are selectively fixed through a group of fourth fixing holes 231 on the bottom of the fixing box 1 according to the space occupied by the battery module 3 to be fixed, so as to flexibly adjust the size of the first chamber 111.

Optionally, the third fixing hole 224 is a through hole, and the fourth through hole is a threaded hole, and at this time, the baffle 22 can be fixed at the bottom of the fixing box 1 by using a fixing screw; or the third fixing hole 224 and the fourth fixing hole 231 are through holes, and the baffle plate 22 may be fixed to the bottom of the fixing box 1 by using fixing bolts.

Alternatively, the plurality of sets of fourth fixing holes 231 are uniformly distributed in the direction perpendicular to the side plate 211, and the distance between two adjacent sets of fourth fixing holes 231 is equal to the size of one battery module 3 in the direction perpendicular to the side plate 211. In this way, when one row of the battery modules 3 (one group of the battery modules 3 parallel to the side plate 211) is decreased or increased with respect to the battery modules 3 fixed in the first chamber 111, the blocking plate 22 only needs to be moved in a direction toward the side plate 211 or away from the side plate 211 to a position corresponding to the adjacent group of the fourth fixing holes 231.

Of course, the distance between the adjacent two sets of fourth fixing holes 231 may also be slightly greater than the size of one battery module 3 in the direction perpendicular to the side plates 211. In order to ensure that the baffle 22 can completely abut against the battery modules 3 facing the outside, spacers or the like may be provided between two adjacent battery modules 3 in a direction perpendicular to the side plates 211. Such as a cushion.

In some embodiments, at least one of the

rails

21, 22 has an inward flange at its edge facing away from the bottom of the stationary box 1. So, to fixing at the battery module 3 of first cavity 111, the accessible inturned reason is spacing to the top of battery module 3 to improve the steadiness fixed to battery module 3.

In some embodiments, as shown in fig. 6, the battery box further includes a support assembly 4, and the support assembly 4 is disposed between at least one of the baffles 22 of the enclosure 21 and the opposite side wall of the fixed box 1.

So, through the support component 4 at the inner wall of fixed case 1 with enclose the support between fender 21, the baffle 22 to the improvement is enclosed fender 21, the baffle 22 spacing to battery module 3, avoids baffle 22 and encloses the fixed condition that takes place not hard up between the fender 21, thereby improves the steadiness fixed to battery module 3.

In combination with the structure of the enclosure 21, for the support assembly 4 included in the battery box, the support assembly may be disposed between at least one of the side plates 211, the end plates 212, and the baffle plates 22 and the side wall facing the fixed box 1.

Optionally, the support assembly 4 is a spring telescopic rod, a first end of which abuts against the inner wall of the stationary box 1 and a second end of which abuts against the outer wall of the enclosure 21 or the baffle 22. The specific structure of the spring telescopic rod can refer to the related art, and the embodiment of the application does not limit the structure.

In order to increase the supporting area of the supporting assembly to the enclosure 21 or the baffle 22, a limiting plate is fixed to the second end of the telescopic spring rod, and the limiting plate can directly abut against the side plate of the enclosure 21 or the baffle 22 under the action of the telescopic spring rod.

In some embodiments, as shown in fig. 3, the fixed frame 2 further comprises a bottom plate 23, the bottom plate 23 is located in the fixed box 1, and the enclosure 21 is fixedly connected to the bottom plate 23.

The bottom plate 23 and the enclosure 21 may be an integral structure or a split structure. When the bottom plate 23 and the enclosure 21 are of an integrated structure, the bottom plate 23 can be directly limited in the fixed box 1, so that the situation that the enclosure 21 is separately and fixedly connected with the fixed box 1 is avoided; when the bottom plate 23 and the enclosure 21 are of a split structure, the enclosure 21 can be fixed on the bottom plate 23 in advance, and then the bottom plate 23 is limited in the fixed box 1, so that the situation that the enclosure 21 is separately and fixedly connected with the fixed box 1 is avoided.

The enclosure 21 is limited in the fixed box 1 through the bottom plate 23, so that the problem of low efficiency in the process of fixing the enclosure 21 in the fixed box 1 due to the limitation of the space in the fixed box 1 is avoided, and the fixing efficiency of the fixed frame 2 in the fixed box 1 is improved.

Wherein, the bottom plate 23 is fixedly connected with the bottom of the fixed box 1 or integrally connected with the bottom of the fixed box. The bottom plate is fixed to the bottom of the fixed box 1 by welding, but may be fixed to the bottom of the fixed box 1 by bonding, screwing, or the like, which is not limited in the embodiment of the present application. When the bottom plate 23 is welded to the bottom of the fixed box 1, the bottom plate 23 is fixed in the fixed box 1, and the heat conductivity between the bottom plate 23 and the bottom of the fixed box 1 can be improved.

In some embodiments, the side of the bottom plate 23 facing away from the bottom of the stationary box 1 is provided with a heat conducting layer. So, can effectively improve the heat-conduction efficiency between the battery module 3 of treating fixed and the bottom plate 23 through the setting of heat-conducting layer, and then improve the heat-conduction efficiency between battery module 3 and the fixed case 1.

Optionally, the heat conducting layer is a heat conducting glue or a heat conducting pad, but may also be other materials having heat conducting property, adhesive property, and the like. Thus, taking the heat-conducting adhesive as an example, not only can the heat-conducting property between the battery module 3 and the fixing box 1 be improved, but also the stability of fixing the battery module 3 in the first chamber 111 can be improved.

In combination with the above-described manner in which the depth of the baffle plate 22 is adjustable on the opening side of the enclosure 21, when the fixed frame 2 includes the bottom plate 23, the baffle plate 22 may be fixed to the bottom plate 23 and the position of the baffle plate on the bottom plate 23 may be adjustable. Reference is made in particular to the above-mentioned case in which the baffle 22 is fixed to the bottom of the stationary box 1.

Illustratively, as shown in fig. 7, the baffle plate 22 has a second burring 223 along the edge of the fixed box 1 near the bottom of the fixed box 1 in the depth direction of the fixed box 1, the second burring 223 has a plurality of third fixing holes 224 spaced apart in the direction parallel to the horizontal direction of the side plate 211, and the bottom plate 23 has a plurality of sets of fourth fixing holes 231 spaced apart side by side in the direction perpendicular to the side plate 211; each set of the fourth fixing holes 231 includes a plurality of fourth fixing holes 231 spaced apart in a direction horizontally parallel to the side plate 211, and the plurality of fourth fixing holes 231 correspond to the plurality of third fixing holes 224 one to one.
