[0007] A limiting assembly is arranged on the support member and is located between the first bearing area and the second bearing area. The limiting assembly is used to limit the first battery carried in the first bearing area and the second battery carried in the second bearing area.

[0008] In the embodiment of the present application, the first bearing area and the second bearing area of ​​the support member are used to bear the first battery and the second battery respectively, so that when the overall number of batteries increases, it is convenient to increase the capacity, thereby meeting the demand for increased capacity.

[0009] According to one embodiment of the present application, the limiting assembly includes:

[0010] A separation mechanism, fixed on the support member and used for separating the bearing surface into the first bearing area and the second bearing area;

[0011] A limiting mechanism is fixed on the separating mechanism and has a first limiting portion facing the first carrying area and a second limiting portion facing the second carrying area, the first limiting portion is used to insert the positioning portion of the first battery carried in the first carrying area, and the second limiting portion is used to insert the positioning portion of the second battery carried in the second carrying area.

[0012] In the implementation manner of the present application, the carrying surface is separated by a separation mechanism, thereby facilitating the placement of the first battery in the first carrying area and the second battery in the second carrying area; the first limiting portion cooperates with the positioning portion of the first battery, and the second limiting portion cooperates with the positioning portion of the second battery, thereby achieving the limitation of the first battery and the second battery in multiple directions, thereby improving the limitation effect.

[0013] According to an embodiment of the present application, the support member further has a limiting surface, the limiting surface extends along the length direction of the bearing surface, and the limiting surface is perpendicular to the bearing surface.

[0014] In the implementation manner of the present application, by setting the limiting surface, the first battery and the second battery are limited in the width direction of the carrying surface, thereby further improving the limiting effect of the first battery and the second battery, and improving the stability of the first battery and the second battery carried on the battery holder.

[0015] According to an embodiment of the present application, the limiting surface includes a first guide surface and a second guide surface;

[0016] The first guide surface is located on a side of the limiting assembly close to the first bearing area, and an angle between an extension direction of the first guide surface away from the limiting assembly and a length direction of the first bearing area away from the second bearing area is an acute angle;

[0017] The second guide surface is located on a side of the limiting assembly close to the second bearing area, and an angle between an extension direction of the second guide surface away from the limiting assembly and a length direction of the second bearing area away from the first bearing area is acute.

[0018] In the implementation manner of the present application, a first guide surface and a second guide surface are formed by a limiting surface, so that the first battery carried in the first carrying area is guided by the first guide surface, and the second battery carried in the second carrying area is guided by the second guide surface, so as to adjust the positions of the first battery and the second battery in the width direction of the carrying surface, facilitate the quick cooperation between the positioning portion of the first battery and the first limiting portion, and the quick cooperation between the positioning portion of the second battery and the second limiting portion, thereby improving the fixing efficiency of the batteries.

[0019] According to an embodiment of the present application, wherein the support member comprises a first guide block and a second guide block;

[0020] The first guide block is fixed on the limiting surface and is located on a side of the limiting assembly close to the first bearing area, and a surface of the first guide block away from the limiting surface is inclined in a direction close to the limiting assembly toward a direction away from the limiting surface;

[0021] The second guide block is fixed on the limiting surface and is located on a side of the limiting assembly close to the second bearing area. The surface of the second guide block away from the limiting surface is inclined in a direction close to the limiting assembly toward a direction away from the limiting surface.

[0022] In the implementation mode of the present application, a first guide surface is formed by the side of the first guide block away from the side plate, and a second guide surface is formed by the side of the second guide block away from the side plate, so that the first battery carried in the first bearing area is guided by the first guide surface, and the second battery carried in the second bearing area is guided by the second guide surface, so as to adjust the positions of the first battery and the second battery in the width direction of the bearing surface, facilitate the rapid cooperation between the positioning portion of the first battery and the first limiting portion, and the rapid cooperation between the positioning portion of the second battery and the second limiting portion, thereby improving the fixing efficiency of the battery and avoiding damage to the limiting surface structure.

[0023] According to an embodiment of the present application, the battery holder further includes a first elastic member and a second elastic member;

[0024] The first elastic member is fixed to a side of the partition mechanism facing the first bearing area, and the second elastic member is fixed to a side of the partition mechanism facing the second bearing area.

[0025] In the implementation manner of the present application, by providing the first elastic member and the second elastic member, when the battery is inserted into the first bearing area and the second bearing area, the elastic buffering action of the first elastic member and the second elastic member can avoid hard contact between the inserted battery and the limiting mechanism, thereby avoiding damage to the battery due to bumps.

[0026] According to an embodiment of the present application, the partition mechanism includes a first baffle and a second baffle;

[0027] The first baffle plate and the second baffle plate are both vertically fixed to the support member, the first baffle plate and the second baffle plate are spaced apart, and the first baffle plate is located at the first end of the first bearing area, and the second baffle plate is located at the first end of the second bearing area.

[0028] In the implementation manner of the present application, the bearing surface is separated into a first bearing area and a second bearing area by a first baffle plate and a second baffle plate. At the same time, the tail of the first battery is blocked and limited by the first baffle plate, and the tail of the second battery is blocked and limited by the second baffle plate, thereby increasing the blocking area of ​​the battery and improving the blocking and limiting effect.

[0029] According to one embodiment of the present application, the partition mechanism also includes a connecting plate, which is located between the first baffle plate and the second baffle plate, and the connecting plate is fixedly connected to the first baffle plate and the second baffle plate at both ends along the length direction of the support member, and at least one of the first baffle plate, the second baffle plate and the connecting plate is fixedly connected to the support member.

[0030] In the implementation mode of the present application, since the connecting plate connects the first baffle plate and the second baffle plate into an integrated structure, the number of structural members included in the battery holder can be reduced. At the same time, since the first baffle plate and the second baffle plate are connected into an integrated structure, only at least one of the first baffle plate, the second baffle plate and the connecting plate needs to be fixedly connected to the support member, thereby further improving the fixing efficiency of the partition mechanism.

[0031] According to one embodiment of the present application, the limiting mechanism includes a first protrusion formed on the side of the first baffle plate facing the first bearing area, and a second protrusion formed on the side of the second baffle plate facing the second bearing area, the first protrusion forms the first limiting portion, and the second protrusion forms the second limiting portion.

[0032] In the implementation manner of the present application, the first and second limiting portions of the limiting mechanism are formed by the first and second protrusions, and then the first and second protrusions cooperate with the positioning portions of the first and second battery tails respectively to limit the batteries in multiple directions.

[0033] According to one embodiment of the present application, the limiting mechanism includes a limiting rod, which is fixedly connected to the partition mechanism, and the limiting rod passes through the partition mechanism and both ends extend out of the partition mechanism to form the first limiting portion and the second limiting portion.

[0034] In the implementation manner of the present application, the first limiting portion and the second limiting portion can be formed by the two ends of the limiting rod, and then the two ends of the limiting rod respectively cooperate with the positioning portions of the tails of the first battery and the second battery to limit the batteries in multiple directions, while reducing the number of structural parts included in the battery bracket.

[0035] According to an embodiment of the present application, ends of the first limiting portion and the second limiting portion are both in a conical structure.

[0036] In the embodiment of the present application, by setting the end of the conical structure, the cross-sectional area of ​​the end point of the limiting portion can be reduced, thereby facilitating the end of the limiting portion to be accurately inserted into the positioning portion of the rear of the battery, and then under the guiding action of the inclined surface of the conical structure, the end of the limiting portion is ensured to be quickly inserted into the positioning portion of the rear of the battery.

[0037] According to an embodiment of the present application, the carrying surface further includes a first fixing portion connected to the second end of the first carrying area, and a second fixing portion connected to the second end of the second carrying area;

[0038] The first fixing portion is used for fixing and connecting with a first battery carried on the first carrying area, and the second fixing portion is used for fixing and connecting with a second battery carried on the second carrying area.

[0039] In the embodiment of the present application, since the first fixing portion and the second fixing portion are end structures of the bearing surface in the length direction, this can further fix the battery while avoiding extending out of the battery case in the width direction of the battery, thereby improving the space utilization of the battery.

[0040] According to one aspect of the present application, there is provided an energy storage device, comprising a plurality of pairs of battery holders as described in the above aspect, wherein a pair of the battery holders arranged opposite to each other in a horizontal direction form two battery accommodating positions.

[0078] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0079] The embodiment of the present application provides a battery holder 40 , which forms a battery bracket with a battery accommodating position by a pair of battery holders 40 arranged opposite to each other, thereby fixing the battery 50 .

[0080] like Figure 1 and Figure 2As shown, the battery holder 40 includes: a support member 41 and a limiting assembly 42, the support member 41 has a bearing surface 411, the bearing surface 411 has a first bearing area 4111 and a second bearing area 4112 distributed along the length direction, the first bearing area 4111 is used to bear the first battery 51, and the second bearing area 4112 is used to bear the second battery 52; the limiting assembly 42 is arranged on the support member 41 and is located between the first bearing area 4111 and the second bearing area 4112, the limiting assembly 42 is used to limit the first battery 51 carried in the first bearing area 4111 and the second battery 52 carried in the second bearing area 4112.

[0081] In the implementation mode of this application, Figure 1 and Figure 2 As shown, when the battery is fixed on a battery bracket formed by a pair of battery holders 40, the first bearing area 4111 and the second bearing area 4112 of the support member 41 can respectively bear the first battery 51 and the second battery 52, thereby improving the battery arrangement density and facilitating increasing the capacity of the energy storage device using the battery holder 40.

[0082] In some embodiments, the battery holder 40 further includes a first elastic member and a second elastic member, wherein the first elastic member is fixed on a side of the limiting assembly 42 facing the first bearing area 4111 , and the second elastic member is fixed on a side of the limiting assembly 42 facing the second bearing area 4112 .

[0083] In this way, through the arrangement of the first elastic member, when the first battery 51 and the second battery 52 are respectively inserted into the first bearing area 4111 and the second bearing area 4112, the elastic buffering action of the first elastic member and the second elastic member can avoid hard contact between the inserted first battery 51 and the second battery 52 and the limiting assembly 42, thereby improving the safety of the first battery 51 and the second battery 52 when they are fixed. At the same time, for the first battery 51 and the second battery 52 after being fixed, the vibration reduction of the batteries can be achieved, further ensuring the stability of the battery fixation.

[0084] The structures of the first elastic member and the second elastic member may be the same or different. Taking the first elastic member as an example, the first elastic member may be a compression spring, a rubber pad, or the like.

[0085] In some embodiments, Figure 3 and Figure 4As shown, the limiting assembly 42 includes: a separating mechanism 43 and a limiting mechanism 44, the separating mechanism 43 is fixed on the supporting member 41, and is used to separate the bearing surface 411 into a first bearing area 4111 and a second bearing area 4112; the limiting mechanism 44 is fixed on the separating mechanism 43, and has a first limiting portion 441 facing the first bearing area 4111, and a second limiting portion 442 facing the second bearing area 4112, the first limiting portion 441 is used to insert the positioning portion of the first battery 51 carried in the first bearing area 4111, and the second limiting portion 442 is used to insert the positioning portion of the second battery 52 carried in the second bearing area 4112.

[0086] Among them, the separation mechanism 43 can not only realize the separation of the bearing surface 411, but also can limit the tail of the battery to ensure the insertion depth of the first battery 51 and the second battery 52 in the first bearing area 4111 and the second bearing area 4112 respectively; the positioning part at the tail of the first battery 51 and the positioning part at the tail of the second battery 52 can both be recessed structures, so that after the first limiting part 441 is inserted into the positioning part of the tail of the first battery 51, and the second limiting part 442 is inserted into the positioning part of the tail of the second battery 52, the first battery 51 and the second battery 52 can be limited in multiple directions, thereby improving the stability of the fixation of the first battery 51 and the second battery 52.

[0087] In addition to the structure including the separation mechanism 43 and the limiting mechanism 44 described above, the limiting component 42 may also be other structures, as long as it can limit the first battery 51 carried on the first carrying area 4111 and the second battery 52 carried on the second carrying area 4112. The embodiment of the present application does not limit this. For example, the limiting component 42 may be a T-shaped nail.

[0088] In some embodiments, Figure 3 As shown, the partition mechanism 43 includes a first baffle 431 and a second baffle 432, both of which are fixedly connected to the support member 41, and the first baffle 431 and the second baffle 432 are arranged at intervals, and the first baffle 431 is located at the first end of the first bearing area 4111 (i.e., one end close to the limiting assembly 42), and the second baffle 432 is located at one end of the second bearing area 4112 (i.e., one end close to the limiting assembly 42). In this way, the tail of the first battery 51 carried by the first bearing area 4111 can be blocked and limited by the first baffle 431, and the tail of the second battery 52 carried by the second bearing area 4112 can be blocked and limited by the second baffle 432, so as to achieve the adjustment of the insertion depth of the first battery 51 and the second battery 52.

[0089] Among them, in combination with the above-mentioned battery holder 40 also including a first elastic member and a second elastic member, the first elastic member is fixed on the side of the first baffle 431 facing the first bearing area 4111, and the second elastic member is fixed on the side of the second baffle 432 facing the second bearing area 4112.

[0090] Optionally, the first baffle 431 and the second baffle 432 are both welded to the support member 41 , or fixed to the support member 41 in other ways, which is not limited in the embodiments of the present application.

[0091] Optionally, the support member 41 has positioning grooves corresponding to the first baffle 431 and the second baffle 432, so that the setting of the positioning grooves facilitates determining the fixed positions of the first baffle 431 and the second baffle 432 on the support member 41, thereby improving the fixing efficiency of the first baffle 431 and the second baffle 432.

[0092] For example, Figure 5 and Figure 6 As shown, a first positioning groove 4123 and a second positioning groove 4124 are provided on the bearing surface 411 of the support member 41 , so that the first baffle plate 431 is positioned through the first positioning groove 4123 , and the second baffle plate 432 is positioned through the second positioning groove 4124 .

[0093] Furthermore, if Figure 3 and Figure 6 As shown, the partition mechanism 43 also includes a connecting plate 433, which is located between the first baffle plate 431 and the second baffle plate 432. The connecting plate 433 is fixedly connected to the first baffle plate 431 and the second baffle plate 432 at both ends along the length direction of the support member 41, and at least one of the first baffle plate 431, the second baffle plate 432 and the connecting plate 433 is fixedly connected to the support member 41.

[0094] Since the connecting plate 433 connects the first baffle plate 431 and the second baffle plate 432 into an integrated structure, the number of structural members included in the battery holder 40 can be reduced. At the same time, since the first baffle plate 431 and the second baffle plate 432 are connected into an integrated structure, only at least one of the first baffle plate 431, the second baffle plate 432 and the connecting plate 433 needs to be fixedly connected to the support member 41, thereby further improving the fixing efficiency of the partition mechanism 43.

[0095] In some embodiments, Figure 3 or Figure 6 As shown, the limiting mechanism 44 includes a limiting rod (not shown in the figure), which is fixedly connected to the partition mechanism 43, the limiting rod passes through the partition mechanism 43, and both ends of the limiting rod extend out of the partition mechanism 43 to form a first limiting portion 441 and a second limiting portion 442.

[0096] In this way, the first limiting portion 441 and the second limiting portion 442 can be formed respectively by the two ends of the limiting rod, and then the first battery 51 and the second battery 52 can be limited in multiple directions by the ends of the limiting rod and the positioning holes at the tail of the first battery 51 and the positioning holes at the tail of the second battery 52. ​​In addition, since only one limiting rod is needed to form the first limiting portion 441 and the second limiting portion 442, the number of structural parts included in the battery bracket 40 can be reduced.

[0097] Optionally, the ends of the first limiting portion 441 and the second limiting portion 442 are both tapered structures. In this way, the cross-sectional areas of the ends of the two limiting portions can be reduced, so that the first limiting portion 441 and the second limiting portion 442 are easily inserted into the positioning portion at the tail of the first battery 51 and the positioning portion at the tail of the second battery 52, respectively, and then under the guidance of the inclined surface of the tapered structure, the first limiting portion 441 and the second limiting portion 442 can respectively quickly limit the first battery 51 and the second battery 52.

[0098] The ends of the first limiting portion 441 and the second limiting portion 442 may be conical structures or pyramidal structures, etc., which may be determined in combination with the cross section of the limiting rod. For example, the cross section of the limiting rod is circular, in which case the ends of the first limiting portion 441 and the second limiting portion 442 are conical structures, or the cross section of the limiting rod is elliptical, in which case the ends of the first limiting portion 441 and the second limiting portion 442 are elliptical cone structures, or the cross section of the limiting rod is rectangular, in which case the ends of the first limiting portion 441 and the second limiting portion 442 are pyramidal structures.

[0099] In other embodiments, in combination with the above-mentioned separation mechanism 43 including a first baffle plate 431 and a second baffle plate 432, the limiting mechanism 44 includes a first protrusion formed on the side of the first baffle plate 431 facing the first bearing area 4111, and a second protrusion formed on the side of the second baffle plate 432 facing the second bearing area 4112, the first protrusion forming a first limiting portion 441, and the second protrusion forming a second limiting portion 442.

[0100] In this way, the first protrusion and the second protrusion form two limiting parts of the limiting mechanism 44, and then the first protrusion and the second protrusion cooperate with the positioning part at the tail of the first battery 51 and the positioning part at the tail of the second battery 52 respectively, so as to limit the first battery 51 and the second battery 52 in multiple directions.

[0101] Optionally, the first protrusion and the second protrusion may both be conical protrusions, such as conical protrusions or pyramidal protrusions, etc. Alternatively, the end surface edges of the first protrusion and the second protrusion away from the separation mechanism 43 may have arc chamfers.

[0102] In combination with the above-mentioned battery holder 40 including the first elastic member and the second elastic member, taking the case where both the first elastic member and the second elastic member are compression springs as an example, the first elastic member is sleeved on the first limiting portion 441 of the limiting mechanism 44, the first limiting portion 441 protrudes from the first elastic member, or the first elastic member protrudes from the first limiting portion 441; the second elastic member is sleeved on the second limiting portion 442 of the limiting mechanism 44, the second limiting portion 442 protrudes from the second elastic member, or the second elastic member protrudes from the second limiting portion 442.

[0103] Taking the first elastic member as an example, when the first limiting portion 441 protrudes from the first elastic member, when the first battery 51 is inserted into the first bearing area 4111, the positioning portion at the tail of the first battery 51 can first be limited and matched with the first limiting portion 441, so that the first elastic member is directional compressed under the orientation of the first limiting portion 441 to avoid bending and deformation of the first elastic member. When the first elastic member protrudes from the first limiting portion 441, when the first battery 51 is inserted into the first bearing area 4111, the tail of the first battery 51 first contacts the first elastic member, so that under the buffering of the first elastic member, the first limiting portion 441 is prevented from hard contact with the tail of the first battery 51 when the positioning portion at the tail of the first battery 51 is not aligned with the first limiting portion 441, thereby improving the safety of the first battery 51.

[0104] In the embodiment of the present application, the support member 41 is a long strip structure, and a planar structure, or a cross-section is an L-shaped structure, a T-shaped structure, etc., as long as the bearing surface 411 can be formed.

[0105] Take the L-shaped cross section of the support member 41 as an example. Figure 1 or Figure 5 As shown, the support member 41 further has a limiting surface 412 , which intersects with the bearing surface 411 , and the limiting surface 412 extends along the length direction of the bearing surface 411 .

[0106] The angle formed by the limiting surface 412 and the bearing surface 411 can be an acute angle, an obtuse angle, or a right angle. When the limiting surface 412 is perpendicular to the bearing surface 411, the contact area between the limiting surface 412 and the battery can be increased, thereby improving the limiting effect on the battery.

[0107] In combination with the case where the partition mechanism 43 described above includes the first baffle plate 431 and the second baffle plate 432, the first baffle plate 431 and the second baffle plate 432 are fixed on the bearing surface 411 of the support member 41, or fixed on the limiting surface 412 of the support member 41, or fixed to the bearing surface 411 and the limiting surface 412 of the support member 41 at the same time. In the case where they are fixed to the bearing surface 411 and the limiting surface 412 at the same time, the bearing surface 411 and the limiting surface 412 both have a first positioning groove 4123 corresponding to the first baffle plate 431, and a second positioning groove 4124 corresponding to the second baffle plate 432. In this way, by providing the two first positioning grooves 4123 and the two second positioning grooves 4124, the stability of the pre-fixation of the first baffle plate 431 and the second baffle plate 432 is further improved.

[0108] In some embodiments, Figure 6 As shown, the limiting surface 412 includes a first guide surface 413 and a second guide surface 414, the first guide surface 413 is located on the side of the limiting component 42 close to the first bearing area 4111, and the extension direction of the first guide surface 413 away from the limiting component 42 forms an acute angle with the length direction of the first bearing area 4111 away from the second bearing area 4112; the second guide surface 414 is located on the side of the limiting component 42 close to the second bearing area 4112, and the extension direction of the second guide surface 414 away from the limiting component 42 forms an acute angle with the length direction of the second bearing area 4112 away from the first bearing area 4111.

[0109] The first guide surface 413 has a first side edge close to the stopper assembly 42 and a second side edge far from the stopper assembly 42, and the second side edge is located between the first side edge and the stopper assembly 42 in the width direction of the bearing surface 411; the second guide surface 414 has a third side edge close to the stopper assembly 42 and a fourth side edge far from the stopper assembly 42, and the fourth side edge is located between the third side edge and the stopper assembly 42 in the width direction of the bearing surface 411. In this way, when the first battery 51 is inserted into the first bearing area 4111, the position of the first battery 51 in the width direction is adjusted by the first guide surface 413, so as to facilitate the quick cooperation between the positioning portion at the tail of the first battery 51 and the first stopper 441, that is, the positioning portion can be accurately sleeved on the first stopper 441, thereby improving the fixing efficiency of the battery 50.

[0110] Optionally, the first guide surface 413 and the second guide surface 414 are both perpendicular to the bearing surface 411. In this way, when the first battery 51 inserted into the first bearing area 4111 and the second battery 52 inserted into the second bearing area 4112 are guided by the first guide surface 413 and the second guide surface 414, the contact area between the first guide surface 413 and the first battery 51 and the contact area between the second guide surface 414 and the second battery 52 can be increased, thereby avoiding the first guide surface 413 from wearing the side wall of the first battery 51 and avoiding the second guide surface 414 from wearing the side wall of the second battery 52.

[0111] In some embodiments, the end surface of the support member 41 described above is an L-shaped structure, such as Figure 6 As shown, the limiting surface 412 has a first bending section 4121 and a second bending section 4122. The first bending section 4121 is located on the side of the limiting component 42 close to the first bearing area 4111, and the second bending section 4122 is located on the side of the limiting component 42 close to the second bearing area 4112. In this way, the first guide surface 413 and the second guide surface 414 are formed respectively by the area of ​​the limiting surface 412 located in the first bending section 4121 and the area located in the second bending section 4122, thereby avoiding the situation of adding additional structural parts to adjust the position of the battery in the width direction of the bearing surface 411, thereby simplifying the structure of the support member 41.

[0112] When the limiting surface 412 includes a first bending section 4121 and a second bending section 4122 , the limiting surface 412 has a broken notch at a position corresponding to the limiting component 42 , so as to form a first bending section 4121 and a second bending section 4122 on both sides of the notch.

[0113] In other embodiments, the support member 41 includes a first guide block and a second guide block, wherein the first guide block is fixed on the limiting surface 412 and is located on the side of the limiting assembly 42 close to the first bearing area 4111, and the surface of the first guide block that is away from the limiting surface 412 is inclined in the direction away from the limiting surface 412 in the direction close to the limiting assembly 42; the second guide block is fixed on the limiting surface 412 and is located on the side of the limiting assembly 42 close to the second bearing area 4112, and the surface of the second guide block that is away from the limiting surface 412 is inclined in the direction away from the limiting surface 412 in the direction close to the limiting assembly 42. In this way, the first guide surface 413 can be formed by the surface of the first guide block that is away from the limiting surface 412, and the second guide surface 414 can be formed by the surface of the second guide block that is away from the limiting surface 412, thereby realizing the adjustment of the position of the battery in the width direction of the bearing surface 411, and avoiding damage to the structure of the limiting surface 412.

[0114] Optionally, the first guide block can be a right-angled trapezoidal block, in which case the side surface where the oblique waist of the right-angled trapezoidal block is located forms the first guide surface 413; or the first guide block can be a right-angled triangle block, in which case the side surface where the hypotenuse of the right-angled triangle block is located forms the first guide surface 413.

[0115] In some embodiments, Figure 7 and Figure 8 As shown, the bearing surface 411 also includes a first fixing portion 4113 connected to the second end of the first bearing area 4111 (the end away from the limiting assembly 42), and a second fixing portion 4114 connected to the second end of the second bearing area 4112 (the end away from the limiting assembly 42); the first fixing portion 4113 is used to be fixedly connected to the first battery 51 carried by the first bearing area 4111, and the second fixing portion 4114 is used to be fixedly connected to the second battery 52 carried by the second bearing area 4112.

[0116] Since the first fixing portion 4113 and the second fixing portion 4114 are both end structures of the carrying surface 411 in the length direction, this avoids the situation where the battery occupies a large space in the width direction of the carrying surface 411, thereby improving space utilization.

[0117] Among them, the first fixing part 4113 and the second fixing part 4114 both have a fixing hole 4115 that passes through the bearing surface 411, and the front ends of the first battery 51 and the second battery 52 both have mounting holes. After the fixing hole 4115 of the first fixing part 4113 is aligned with the mounting hole of the first battery 51 carried by the first bearing area 4111 (that is, they overlap in the direction perpendicular to the bearing surface 411), they are locked by a locking bolt to fix the front end of the first battery 51; after the fixing hole 4115 of the second fixing part 4114 is aligned with the mounting hole of the second battery 52 carried by the second bearing area 4112 (that is, they overlap in the direction perpendicular to the bearing surface 411), they are locked by a locking bolt to fix the front end of the second battery 52.

[0118] Among them, Figure 8 As shown, the front end of the battery has a fixing plate 53, and the fixing plate 53 has a mounting hole. When the battery is fixed in the corresponding bearing area, the fixing plate 53 fits the bearing surface 411, thereby improving the stability of the front end of the battery. In addition, when the front end of the battery is fixed to the fixing part, combined with the limiting blocking of the battery tail by the separation mechanism 43, it is possible to easily achieve the alignment of the fixing hole 4115 of the fixing part and the mounting hole on the fixing plate 53, thereby improving the fixing efficiency of the front end of the battery.

[0119] Of course, in addition to fixing the front end of the battery by setting fixing holes 4115 on the first fixing portion 4113 and the second fixing portion 4114, the front end of the battery can also be fixed by other methods, which is not limited in the embodiments of the present application.

[0120] In some embodiments, Figure 5 or Figure 7 As shown, the battery bracket 40 further includes a reinforcing rib 45 , which is fixed to a side of the support member 41 away from the bearing surface 411 .

[0121] Among them, when the battery holder 40 is fixed on the fixed frame, the reinforcing ribs 45 are fixedly connected to the fixed frame at the same time. In this way, under the supporting effect of the reinforcing ribs 45, the supporting strength of the first bearing area 4111 and the second bearing area 4112 on the support member 41 for the battery is improved, thereby avoiding deformation of the support member 41 due to load-bearing problems.

[0122] Among them, the reinforcing rib 45 can be an integral structure, that is, a strip structure extending along the length direction of the support member 41. In this case, the cross-section of the reinforcing rib 45 is a triangle or a right-angled trapezoid, etc.; or the reinforcing rib 45 includes a plurality of reinforcing blocks distributed along the length direction of the support member 41. The view of the reinforcing block in the length direction of the support member 41 can be a triangle, a right-angled trapezoid, etc., and the view in the width direction of the support member 41 can be I-shaped, L-shaped, T-shaped, etc. The implementation mode of the present application does not limit this, as long as the supporting strength of the first bearing area 4111 and the second bearing area 4112 of the support member 41 to the battery can be strengthened.

[0123] The embodiment of the present application also provides an energy storage device, which includes a plurality of pairs of battery holders 40 described in the above embodiment, and a pair of battery holders 40 arranged opposite to each other in the horizontal direction form two battery accommodating positions. In this way, in combination with the above, the energy storage device of the present application can improve the stability of battery fixation, while improving the utilization rate of the battery in the width direction, facilitating the increase of battery distribution density in the width direction, and further facilitating the increase of the electrical capacity of the energy storage device. Among them, the energy storage device can be a battery cabinet, energy storage container, etc. for installing multiple batteries. Next, the energy storage device is explained as an energy storage container as an example.

[0124] like Fig. 9 and Fig.10As shown, the energy storage container 100 includes: an outer frame 10, a support beam assembly 20, a plurality of inner frames 30 and a plurality of pairs of battery holders 40; the outer frame 10 encloses a accommodating space; the support beam assembly 20 is located at the bottom of the outer frame 10 and is fixedly connected to the outer frame 10; a plurality of inner frames 30 are distributed in the accommodating space along the width direction of the outer frame 10, and the accommodating space is divided into a plurality of battery compartments, and the plurality of inner frames 30 are supported on the support beam assembly 20 and are fixedly connected to the outer frame 10; a plurality of pairs of battery holders 40, a pair of battery holders 40 are respectively fixedly connected to two adjacent inner frames 30 to form a battery accommodating position, and a plurality of pairs of battery holders 40 are fixedly arranged at intervals between two adjacent inner frames 30 in the height direction of the outer frame 10.

[0125] In the embodiment of the present application, the inner frame 30 is fixed in the accommodating space of the outer frame 10, and the battery bracket 40 is fixed on the inner frame 30, so as to form an energy storage container 100 with an integral structure, which simplifies the frame structure for fixing the battery; in addition, a support beam assembly 20 is provided at the bottom of the outer frame 10, and the inner frame 30 is supported on the support beam assembly 20, so as to improve the supporting strength of the inner frame 30, thereby improving the structural strength of the energy storage container 100, and avoiding the hidden danger of damage of the energy storage container 100 due to heavy load-bearing.

[0126] The depth direction of the outer frame 10 is the direction indicated by D as shown in the figure, the width direction of the outer frame 10 is the direction indicated by W as shown in the figure, and the height direction of the outer frame 10 is the direction indicated by H as shown in the figure. The plane where the inner frame 30 is located is parallel to the depth direction D and the height direction H of the outer frame 10, so that the storage space of the outer frame 10 can be divided into multiple cubic battery compartments. In addition, in addition to dividing the storage space into multiple battery compartments, multiple inner frames 30 can also separate electrical compartments for placing electrical devices.

[0127] In some embodiments, Fig. 9 or Fig.10 As shown, the outer frame 10 includes a base frame 11, a top frame 12 and a plurality of columns 13; the base frame 11 and the top frame 12 are arranged relatively to each other, and both ends of each column 13 in the plurality of columns 13 are respectively fixedly connected to the base frame 11 and the top frame 12, and the support beam assembly 20 is fixedly connected to the base frame 11.

[0128] Among them, the outer frame 10 can be a cubic structure, in which case the base frame 11 and the top frame 12 are both rectangular structures of the same size. The outer frame 10 includes at least four columns 13, and the two ends of each column 13 are respectively fixedly connected to a corner of the base frame 11 and a corner of the top frame 12.

[0129] For example, the bottom frame 11 and the top frame 12 are both rectangular structures. Fig.11As shown, the bottom frame 11 includes a pair of bottom cross beams 111 and a pair of bottom longitudinal beams 112 arranged opposite to each other. The pair of bottom cross beams 111 and the pair of bottom longitudinal beams 112 are sequentially fixedly connected to form a rectangular bottom frame 11. Fig.11 As shown, the top frame 12 includes a pair of top cross beams 121 and a pair of top longitudinal beams 122 arranged opposite to each other, and the pair of top cross beams 121 and the pair of top longitudinal beams 122 are successively connected and fixed to form a rectangular top frame 12. For the bottom frame 11 of the rectangular structure, the ends of the support cross beams 21 are respectively fixedly connected to the pair of bottom longitudinal beams 112; for the top frame 12 of the rectangular structure, the inner frame 30 is fixedly connected to the top cross beam 121 of the top frame 12.

[0130] Among them, the longitudinal beam involved in the present application refers to a beam structure arranged along the depth direction D of the outer frame 10 (the length direction of the longitudinal beam is parallel to, or approximately parallel to, the depth direction D of the outer frame 10). The longitudinal beams here include not only the bottom longitudinal beams 112 of the base frame 11 and the top longitudinal beams 122 of the top frame 12, but also other longitudinal beam structures, such as the support longitudinal beams 22 of the support beam assembly 20 described below. The crossbeams involved in the present application refer to a beam structure arranged along the width direction W of the outer frame 10 (the length direction of the crossbeam is parallel to, or approximately parallel to, the width direction W of the outer frame 10). The crossbeams here include not only the bottom crossbeams 111 of the base frame 11 and the top crossbeams 121 of the top frame 12, but also other crossbeam structures, such as the support crossbeams 21 of the support beam assembly 20 described below.

[0131] The ends of the upright posts 13 and the corners of the bottom frame 11 or the top frame 12 may be welded or fixedly connected by angle pieces. Of course, welding may be performed first and then fixedly connected by angle pieces to improve the stability of the connection between the upright posts 13 and the bottom frame 11 or the top frame 12, thereby improving the supporting strength of the outer frame 10.

[0132] Optionally, in combination with the above, the top frame 12 includes, in addition to the top cross beam 121 and the top longitudinal beam 122, Fig.11 As shown, the top frame 12 further includes a plurality of reinforcing beams 123 arranged along the width direction W of the outer frame 10, and the plurality of reinforcing beams 123 correspond to the plurality of inner frames 30 one by one, and the top of an inner frame 30 is fixedly connected to the corresponding reinforcing beam 123. In this way, the inner frame 30 is fixedly connected to the corresponding reinforcing beam 123, so that the fixing area of ​​the inner frame 30 can be increased to improve the stability of the fixing of the inner frame 30, thereby further improving the stability of the energy storage container 100.

[0133] The two ends of the reinforcement beam 123 are respectively fixedly connected to a pair of top cross beams 121. The length direction of the reinforcement beam 123 is parallel to the depth direction D of the outer frame 10, that is, parallel to the plane where the inner frame 30 is located. In this way, by adjusting the top structure of the inner frame 30, the inner frame 30 and the reinforcement beam 123 can be fixed at multiple points, and the inner frame 30 and the reinforcement beam 123 can be fixed along the height direction H of the outer frame 10, thereby improving the suspension strength of the inner frame 30.

[0134] Among them, the reinforcement beam 123 can be square steel, L-shaped steel or H-shaped steel, etc., as long as the reinforcement beam 123 can be fixedly connected to the top cross beam 121 and the inner frame 30, the implementation mode of the present application does not limit this.

[0135] In some embodiments, Fig.10 ,as well as Fig.12 or Fig.13 As shown, the support beam assembly 20 includes a plurality of support longitudinal beams 22, which are arranged at intervals along the width direction of the outer frame 10, and the two ends of the support longitudinal beams 22 are respectively fixedly connected to the two ends of the depth direction of the outer frame 10; the plurality of support longitudinal beams 22 correspond to the plurality of inner frames 30 one by one, and one inner frame 30 is supported on one support longitudinal beam 22. In this way, the support beam assembly 20 is configured as a plurality of support longitudinal beams 22, so as to independently support the plurality of inner frames 30, thereby facilitating the improvement of the support strength of the plurality of inner frames 30, and further facilitating the improvement of the overall structural strength of the energy storage container 100.

[0136] Among them, in the case where the inner frame 30 is supported on the supporting longitudinal beam 22, the bottom of the inner frame 30 can be supported on the upper surface of the supporting longitudinal beam 22, or the bottom of the inner frame 30 is fixedly connected to the side of the supporting longitudinal beam 22 to achieve support for the inner frame 30. The implementation mode of the present application does not limit this.

[0137] Optionally, in the case where the support beam assembly 20 includes a plurality of support longitudinal beams 22, the tops of the plurality of inner frames 30 are all fixedly connected to the top of the outer frame 10, the plurality of inner frames 30 include a first inner frame 30 and a second inner frame 30, the bottom of the first inner frame 30 is fixedly connected to one support longitudinal beam 22, and the bottom of the second inner frame 30 is fixedly connected to the bottom of the outer frame 10. In this way, by limiting the fixing method of the bottoms of the plurality of inner frames 30, the bottom of the second inner frame 30 is supported on the support longitudinal beam 22, and the second inner frame 30 is fixedly connected to the outer frame 10, so as to facilitate further improving the stability of the support for the second inner frame 30.

[0138] In combination with the above, the bottom of the first inner frame 30 can be supported on the upper surface of the supporting longitudinal beam 22 and fixedly connected to the supporting longitudinal beam 22, or the bottom of the first inner frame 30 can be fixedly connected to the side of the supporting longitudinal beam 22, so as to achieve support for the inner frame 30 while achieving fixed connection of the inner frame 30; the bottom of the second inner frame 30 is supported on the upper surface of the supporting longitudinal beam 22 and fixedly connected to the outer frame 10.

[0139] Of course, in the implementation manner of the present application, in addition to the above-mentioned method to achieve the fixation of the bottom of multiple inner frames 30, the bottoms of multiple inner frames 30 can also be supported and fixed on the corresponding supporting longitudinal beams 22. For details, please refer to the above-mentioned method of supporting and fixing the bottom of the first inner frame 30.

[0140] In other embodiments, Fig.10 ,as well as Fig.12 or Fig.13 As shown, the support beam assembly 20 includes a support beam 21, the two ends of the support beam 21 are respectively fixedly connected to the two ends of the width direction of the outer frame 10, and the multiple inner frames 30 are supported on the support beam 21. In this way, the support beam 21 is used to support the multiple inner frames 30, thereby simplifying the structure of the support beam assembly 20, that is, while ensuring the structural stability of the energy storage container 100, the structure of the energy storage container 100 is simplified.

[0141] The support beam 21 is an H-shaped steel, T-shaped steel, I-shaped steel or square steel, and one side flange of the steel faces the top of the outer frame 10, and the other side flange faces the bottom of the outer frame 10. In this way, when the support beam 21 supports multiple inner frames 30, the support area can be increased, thereby further improving the stability of the support for multiple inner frames 30. In the case where the support beam 21 is an H-shaped steel, T-shaped steel, I-shaped steel or square steel, stress relief holes are provided on the web of the steel to reduce the stress deformation of the support beam 21.

[0142] The length direction of the support beam 21 may be parallel to the width direction of the outer frame 10. The number of the support beams 21 may be one or more. When the number of the support beams 21 is more than one, the multiple support beams 21 are spaced apart along the depth of the outer frame 10, and the two ends of each support beam 21 are fixedly connected to the two ends of the bottom of the outer frame 10 along the width direction. In addition, in the case of including multiple support beams 21, the multiple support beams 21 may be arranged parallel to each other along the width direction W of the outer frame 10.

[0143] Optionally, in combination with the above-mentioned multiple inner frames 30, the accommodating space is divided into an electrical compartment and multiple battery compartments, such as Fig.12 or Fig.13As shown, the support beam 21 includes a notch section 211 located below the electrical compartment, and a relief opening 212 is formed on the side of the notch section 211 away from the bottom of the outer frame 10. In this way, the relief opening 212 formed on the notch section 211 makes the bottom surface of the electrical compartment lower than the bottom surface of the battery compartment, so that the ventilation duct arranged below the electrical compartment can be extended straight to the electrical compartment, thereby facilitating the arrangement of electrical components in the electrical compartment.

[0144] In some other embodiments, Fig.12 or Fig.13 As shown, the support beam assembly 20 includes a support cross beam 21 and multiple support longitudinal beams 22. The arrangement of the support cross beam 21 and multiple support longitudinal beams 22 can refer to the arrangement of the support cross beam 21 and the arrangement of multiple support longitudinal beams 22 respectively explained in the above two embodiments.

[0145] The supporting cross beam 21 is connected to a plurality of supporting longitudinal beams 22. The plurality of inner frames 30 are supported on the corresponding supporting longitudinal beams 22, or are all supported on the supporting cross beam 21, or are simultaneously supported on the supporting cross beam 21 and the corresponding supporting longitudinal beam 22, which is not limited in the embodiment of the present application.

[0146] In some embodiments, the support crossbeam 21 has a plurality of through holes, and one support longitudinal beam 22 passes through one through hole and is fixedly connected to the outer frame 10. In this way, through the through holes provided on the support crossbeam 21, the support longitudinal beam 22 can be fixedly connected to both ends of the depth direction D of the outer frame 10 without destroying the overall structure of the support longitudinal beam 22, so as to further ensure the structural stability of the support beam assembly 20.

[0147] Among them, a plurality of through holes are distributed along the length direction of the supporting cross beam 21, and the number of the through holes can be equal to the number of the supporting longitudinal beams 22, or can be greater than the number of the supporting longitudinal beams 22. In the case where the number of the through holes is greater than the number of the supporting longitudinal beams 22, the through holes through which the supporting longitudinal beams 22 are penetrated can be used as stress release holes of the supporting cross beam 21.

[0148] Among them, after the supporting longitudinal beam 22 passes through the through hole, the supporting longitudinal beam 22 can be supported on the hole wall of the through hole, or it can be fixedly connected to the supporting crossbeam 21 after being supported on the hole wall of the through hole, so as to realize the integrated structure of the supporting crossbeam 21 and multiple supporting longitudinal beams 22, so as to further ensure the structural stability of the supporting longitudinal beam 22.

[0149] Taking the case where the number of the supporting cross beam 21 included in the supporting beam assembly 20 is one as an example, the two ends of each supporting longitudinal beam 22 in the plurality of supporting longitudinal beams 22 are symmetrically distributed relative to the supporting cross beam 21. In this way, by symmetrically arranging the two ends of the supporting longitudinal beam 22, the uniformity of the torque borne on the supporting longitudinal beam 22 can be ensured, and the stability of the supporting longitudinal beam 22 supporting the inner frame 30 can be ensured.

[0150] In other embodiments, the number of the supporting crossbeams 21 described above can be one or more. In this case, each supporting longitudinal beam 22 can be divided into multiple sub-supporting longitudinal beams 22 according to the number of the supporting crossbeams 21, so as to achieve a fixed connection between each supporting longitudinal beam 22 and both ends of the depth direction D of the outer frame 10 without destroying the structure of the supporting crossbeams 21.

[0151] like Fig.12 As shown, the number of the supporting crossbeam 21 is one, and at this time, each of the multiple supporting longitudinal beams 22 includes a first sub-longitudinal beam 221 and a second sub-longitudinal beam 222; the first sub-longitudinal beam 221 and the second sub-longitudinal beam 222 of a supporting longitudinal beam 22 are symmetrically distributed on both sides of the supporting crossbeam 21, and the first end of the first sub-longitudinal beam 221 and the first end of the second sub-longitudinal beam 222 are fixedly connected to the supporting crossbeam 21, and the second end of the first sub-longitudinal beam 221 and the second end of the second sub-longitudinal beam 222 are respectively fixedly connected to the two ends of the depth direction of the outer frame 10. In this way, by setting the first sub-longitudinal beam 221 and the second sub-longitudinal beam 222, the two ends of the first sub-longitudinal beam 221 can be fixedly connected to one side of the supporting beam 21 and one end in the depth direction of the outer frame 10, and the two ends of the second sub-longitudinal beam 222 can be fixedly connected to the other side of the supporting beam 21 and the other end in the depth direction of the outer frame 10, so that the setting of multiple supporting longitudinal beams 22 is achieved without destroying the structure of the supporting beam 21 itself, so as to ensure the structural stability of the energy storage container 100 while ensuring the structural stability of the supporting beam 21.

[0152] Optionally, in the case where the supporting longitudinal beam 22 includes a first sub-longitudinal beam 221 and a second sub-longitudinal beam 222, the inner frame 30 forms a support on one side of the corresponding supporting longitudinal beam 22, that is, the bottom of the inner frame 30 is supported on the first sub-longitudinal beam 221 included in the corresponding supporting longitudinal beam 22 and is fixedly connected to the first sub-longitudinal beam 221, or is supported on the second sub-longitudinal beam 222 included in the corresponding supporting longitudinal beam 22 and is fixedly connected to the second sub-longitudinal beam 222; or the inner frame 30 forms a support on both sides of the corresponding supporting longitudinal beam 22, that is, the bottom of the inner frame 30 is supported on the first sub-longitudinal beam 221 and the second sub-longitudinal beam 222 included in the corresponding supporting longitudinal beam 22, and is fixedly connected to the first sub-longitudinal beam 221 and the second sub-longitudinal beam 222.

[0153] The above embodiment illustrates a case where the number of the supporting beams 21 is one, and the following is an exemplary description assuming that the number of the supporting beams 21 is three. Fig.14 or Fig.15As shown, the support beam assembly 20 includes three support beams 21, and the three support beams 21 are arranged along the depth direction D of the outer frame 10, and the two ends of each support beam 21 are fixedly connected to the two ends of the width direction W of the outer frame 10. The inner frame 30 is supported on the support beam 21 located in the middle position and is fixedly connected to the two support beams 21 on both sides.

[0154] Alternatively, if Fig.14 or Fig.15 As shown, three support beams 21 are connected by multiple support longitudinal beams 22 to form an integral structure. For the three support beams 21, the bottom of the inner frame 30 can be supported on the three support beams 21 at the same time, and fixedly connected with the support beams 21 on both sides, so that the support beams 21 on both sides can not only support the inner frame 30, but also be fixed to the inner frame 30. Moreover, the three support beams 21 can more conveniently support the inner frame 30 at the same height. The space between two adjacent support beams 21 is convenient for forming a wiring or air passage.

[0155] In some embodiments, Fig.16 or Fig.17 As shown, each of the multiple inner frames 30 includes a pair of vertical beams 31 and multiple connecting longitudinal beams 32; the pair of vertical beams 31 are parallel to each other, and the bottom ends of the vertical beams 31 are supported on the support beam assembly 20, the top ends of the vertical beams 31 are fixedly connected to the outer frame 10, and the pair of vertical beams 31 are fixed with multiple battery holders 40; the multiple connecting longitudinal beams 32 are spaced apart along the extension direction of the vertical beams 31, and the two ends of each connecting longitudinal beam 32 are respectively fixedly connected to the pair of vertical beams 31. In this way, the inner frame 30 is formed by connecting the pair of vertical beams 31 and the multiple connecting longitudinal beams 32 to each other, which can increase the structural stability of the inner frame 30, and thus can improve the stability of the battery holder 40 fixed on the inner frame 30.

[0156] The vertical beam 31 involved in the present application refers to a beam structure arranged along the height direction H of the outer frame 10. The longitudinal beam here includes not only the vertical beam 31 of the inner frame 30, but also the reinforcement vertical beam 33 included in the inner frame 30 described below.

[0157] Among them, combined with the above explanation of the support beam assembly 20, when the support beam assembly 20 includes multiple supporting longitudinal beams 22, the bottom end of the vertical beam 31 is supported on the supporting longitudinal beam 22 corresponding to the inner frame 30; when the support beam assembly 20 includes multiple supporting cross beams 21 (taking three supporting cross beams 21 as an example), a pair of vertical beams 31 are respectively supported on two supporting cross beams 21 located on both sides.

[0158] Optionally, a pair of vertical beams 31 and a plurality of connecting longitudinal beams 32 are located in the same plane, so that the space occupied by the inner frame 30 in the width direction W of the outer frame 10 can be reduced, thereby improving the arrangement density of the inner frame 30. Alternatively, a plurality of connecting longitudinal beams 32 extend beyond a pair of vertical beams 31 in the width direction of the outer frame 10, and a battery holder 40 is supported on each of the plurality of connecting longitudinal beams 32. In this way, the battery holder 40 is supported by the portion of the connecting longitudinal beam 32 protruding from the vertical beam 31, so that the load-bearing capacity of the battery holder 40 can be further improved, thereby avoiding the bending and deformation of the battery holder 40 after the battery is fixed.

[0159] In some embodiments, Fig.16 or Fig.17 As shown, each of the multiple inner frames 30 further includes at least one reinforcing vertical beam 33, at least one reinforcing vertical beam 33 is located between a pair of vertical beams 31, and at least one reinforcing vertical beam 33 is fixedly connected to the multiple connecting longitudinal beams 32. In this way, by providing at least one reinforcing vertical beam 33, the structural stability of the inner frame 30 is further improved.

[0160] Optionally, the surfaces of the vertical beam 31, the reinforcing vertical beam 33, and the connecting longitudinal beam 32 on the same side in the width direction W of the outer frame 10 are flush, so that the space occupied by the inner frame 30 in the width direction W of the outer frame 10 can be reduced, thereby improving the arrangement density of the inner frame 30. Alternatively, a plurality of connecting longitudinal beams 32 simultaneously extend beyond a pair of vertical beams 31 and at least one reinforcing vertical beam 33 in the width direction of the outer frame 10, so as to support the battery bracket 40 through the protruding portions of the connecting longitudinal beams 32, thereby further improving the bearing capacity of the battery bracket 40, thereby avoiding the bending and deformation of the battery bracket 40 after the battery is fixed.

[0161] In some embodiments, one of the plurality of connecting longitudinal beams 32 near the bottom end of the vertical beam 31 is supported on the support beam assembly 20. In this way, by arranging the connecting longitudinal beams 32 included in the inner frame 30 to be supported on the support beam assembly 20, the stability of the support beam assembly 20 supporting the inner frame 30 is further improved, thereby improving the structural stability of the energy storage container 100.

[0162] In combination with the above explanation of the support beam assembly 20, when the support beam assembly 20 includes a plurality of support longitudinal beams 22, one of the plurality of connection longitudinal beams 32 close to the bottom end of the vertical beam 31 is integrally supported on a corresponding support longitudinal beam 22 of the inner frame 30. In the case where the bottom end of the vertical beam 31 is supported on the support longitudinal beam 22, the size of the vertical beam 31 in the width direction W of the outer frame 10 may be larger than the size of the support longitudinal beam 22. At this time, in order to ensure that the support longitudinal beam 22 can fully support the bottom end of the vertical beam 31, the support longitudinal beam 22 is provided with protrusions on both sides of the width direction W of the outer frame 10, thereby increasing the support area of ​​the support longitudinal beam 22 on the vertical beam 31.

[0163] When the support beam assembly 20 includes a support cross beam 21, one of the plurality of connection longitudinal beams 32 near the bottom end of the vertical beam 31 is cross-supported on the support cross beam 21. In the case where the first end of the vertical beam 31 is fixedly connected to the support cross beam 21, since the support cross beam 21 extends along the width direction W of the outer frame 10, it is possible to ensure that the first end of the vertical beam 31 is fully supported on the support cross beam 21 in the width direction W of the outer frame 10.
