[0010] Hereinafter, exemplary embodiments will be described more fully with reference to the drawings. However, it should be understood that the exemplary embodiments may be implemented in various forms and are not limited to the embodiments described herein. On the contrary, these embodiments are intended to make the present application more complete and thorough and to fully convey the concept of the exemplary embodiments to those skilled in the art. Since the same reference numerals in the drawings indicate the same or similar structures, detailed descriptions thereof will be omitted.

[0011] An embodiment of the present application provides an energy storage container 100. As shown in FIGS. 1 and 2 , 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 defines a storage 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. The plurality of inner frames 30 are distributed within the storage space along the width direction of the outer frame 10. The plurality of inner frames 30 divide the storage space into a plurality of battery compartments. The plurality of inner frames 30 are supported by the support beam assembly 20. The plurality of inner frames 30 are fixedly connected to the outer frame 10. In the plurality of pairs of battery holders 40, each pair of battery holders 40 is fixedly connected to two adjacent inner frames 30 to form a battery storage position. Along the height direction of the outer frame 10, the plurality of pairs of battery holders 40 are fixed to two adjacent inner frames 30 at intervals.

[0012] In the embodiment of the present application, the inner frame 10 is fixed within the receiving space of the outer frame 30, and the battery holders 40 are fixed to the inner frame 30, thereby forming an energy storage container 100 with an integrated structure and simplifying the framework structure for fixing the batteries. In addition, a support beam assembly 20 is installed at the bottom of the outer frame 10, and the support beam assembly 20 supports the inner frame 30. This improves the support strength for the inner frame 30, thereby improving the structural strength of the energy storage container 100 and preventing damage to the energy storage container 100 due to a large load.

[0013] As shown in the figure, the depth direction of the outer frame 10 is the direction indicated by arrow D, the width direction of the outer frame 10 is the direction indicated by arrow W, and the height direction of the outer frame 10 is the direction indicated by arrow H. The plane of the inner frame 30 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 to dividing the storage space into multiple battery compartments, multiple inner frames 30 can also divide the storage space into electrical compartments for placing electrical devices. Each pair of battery holders 40 includes two battery holders 40, which are fixed to opposite sides of two adjacent inner frames 30.

[0014] In some embodiments, as shown in Figure 1 or 2, 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 installed opposite each other. Of the plurality of columns 13, one end of each column 13 is fixedly connected to the base frame 11, and the other end of each column 13 is fixedly connected to the top frame 12. A support beam assembly 20 is fixedly connected to the base frame 11.

[0015] The outer frame 10 may be a cubic structure, in which the base frame 11 is a rectangular structure of the same size as the top frame 12. The outer frame 10 includes at least four columns 13. One end of each column 13 is fixedly connected to one corner of the base frame 11, and the other end of each column 13 is fixedly connected to one corner of the top frame 12.

[0016] For example, the base frame 11 and the top frame 12 are both rectangular structures. As shown in FIG. 3, the base frame 11 includes a pair of base horizontal beams 111 and a pair of base vertical beams 112 arranged opposite each other. To surround the rectangular base frame 11, the pair of base horizontal beams 111 and the pair of base vertical beams 112 are fixedly connected end to end. As shown in FIG. 3, the top frame 12 includes a pair of top horizontal beams 121 and a pair of top vertical beams 122 arranged opposite each other. To surround the rectangular top frame 12, the pair of top horizontal beams 121 and the pair of top vertical beams 122 are fixedly connected end to end. In the formed rectangular base frame 11, one end of the supporting horizontal beam 21 is fixedly connected to one base vertical beam 112, and the other end of the supporting horizontal beam 21 is fixedly connected to the other base vertical beam 112. With the top frame 12 being a rectangular structure formed, the inner frame 30 is fixedly connected to the top cross beam 121 of the top frame 12 .

[0017] The longitudinal beams according to the present application are beams installed along the depth direction D of the outer frame 10 (the length direction of the longitudinal beams is parallel or approximately parallel to the depth direction D of the outer frame 10). The longitudinal beams here include not only the base longitudinal beams 112 of the base frame 11 and the top longitudinal beams 122 of the top frame 12, but also other longitudinal beams. For example, the supporting longitudinal beams 22 of the support beam assembly 20 described below can be cited. The cross beams according to the present application are beams installed along the width direction W of the outer frame 10 (the length direction of the cross beams is parallel or approximately parallel to the width direction W of the outer frame 10). The cross beams here include not only the base cross beams 111 of the base frame 11 and the top cross beams 121 of the top frame 12, but also other cross beams. For example, the supporting cross beams 21 of the support beam assembly 20 described below can be cited.

[0018] The ends of the columns 13 may be connected to the corners of the base frame 11 or the top frame 12 by welding or by fixed connections via angles. Of course, welding may be performed first, followed by fixed connections via angles to improve the stability of the connections between the columns 13 and the base frame 11 or the top frame 12, thereby improving the supporting strength of the outer frame 10.

[0019] Optionally, in combination with the above description, as shown in FIG. 3 , the top frame 12 includes a top horizontal beam 121 and a top vertical beam 122, as well as a plurality of reinforcing beams 123 arranged along the width direction W of the outer frame 10. The plurality of reinforcing beams 123 correspond one-to-one to the plurality of inner frames 30. The top of each inner frame 30 is fixedly connected to the corresponding reinforcing beam 123. In this way, by the inner frame 30 being fixedly connected to the corresponding reinforcing beam 123, the fixing area of ​​the inner frame 30 can be increased and the fixing stability of the inner frame 30 can be improved, and as a result, the stability of the energy storage container 100 can be further improved.

[0020] Both ends of the reinforcing beams 123 are fixedly connected to a pair of top cross beams 121. The length direction of the reinforcing beams 123 is parallel to the depth direction D of the outer frame 10, that is, the length direction of the reinforcing beams 123 is parallel to the plane on which the inner frame 30 is located. In this way, by adjusting the structure of the top of the inner frame 30, multi-point fixation between the inner frame 30 and the reinforcing beams 123 is achieved, and fixation between the inner frame 30 and the reinforcing beams 123 in the height direction H of the outer frame 10 is ensured, resulting in improved strength for suspending the inner frame 30.

[0021] The reinforcing beam 123 may be a square steel, an L-shaped steel, an H-shaped steel, or the like, as long as it can securely connect the reinforcing beam 123 to the top cross beam 121 and the inner frame 30. The embodiments of the present application are not limited thereto.

[0022] In some embodiments, as shown in FIGS. 2 and 4 or 5 , the support beam assembly 20 includes a plurality of longitudinal support beams 22. The plurality of longitudinal support beams 22 are arranged at intervals along the width direction of the outer frame 10. Both ends of the longitudinal support beams 22 are fixedly connected to both ends of the outer frame 10 in the depth direction. The plurality of longitudinal support beams 22 correspond one-to-one to the plurality of inner frames 30. Each inner frame 30 is supported by the corresponding longitudinal support beam 22. In this way, since the support beam assembly 20 includes a plurality of longitudinal support beams 22, it is possible to realize that a plurality of inner frames 30 are supported by a plurality of longitudinal support beams 22 of a single support beam assembly 20. This makes it easy to improve the support strength for the plurality of inner frames 30, and therefore, to improve the overall structural strength of the energy storage container 100.

[0023] When the inner frame 30 is supported by the supporting longitudinal beams 22, to realize support for the inner frame 30, the bottom of the inner frame 30 may be supported by the upper surface of the supporting longitudinal beams 22, or the bottom of the inner frame 30 may be fixedly connected to the side of the supporting longitudinal beams 22. The embodiment of the present application is not limited thereto.

[0024] Optionally, when the support beam assembly 20 includes a plurality of longitudinal support beams 22, the tops of the plurality of inner frames 30 are all fixedly connected to the top of the outer frame 10, and the bottom of each inner frame 30 is fixedly connected to the side of a corresponding one of the longitudinal support beams 22 and also fixedly connected to the bottom of the outer frame 10, thereby improving the stability of support for the inner frames 30.

[0025] Of course, in the embodiment of the present application, in addition to realizing the fixing of the bottoms of the plurality of inner frames 30 in the manner described above, the bottoms of each of the plurality of inner frames 30 may also be supported and fixed by a corresponding longitudinal supporting beam 22. Specifically, the bottom of each inner frame 30 is supported by the upper surface of a corresponding longitudinal supporting beam 22 and is fixedly connected to the bottom of the outer frame 10. In this way, by limiting the manner in which the bottoms of the plurality of inner frames 30 are fixed, the stability of support for the inner frames 30 is further improved.

[0026] 2 and 4 or 5, the support beam assembly 20 includes a support cross beam 21. Both ends of the support cross beam 21 are fixedly connected to both ends of the outer frame 10 in the width direction. The multiple inner frames 30 are supported by the support cross beam 21. In this way, by realizing support for the multiple inner frames 30 via the support cross beam 21, the structure of the support beam assembly 20 is simplified. That is, the structural stability of the energy storage container 100 is ensured and the structure of the energy storage container 100 is simplified.

[0027] The supporting cross beams 21 are H-shaped steel, T-shaped steel, I-shaped steel, or square steel. The upper flange of the steel faces the top of the outer frame 10, and the lower flange of the steel faces the bottom of the outer frame 10. In this way, when multiple inner frames 30 are supported via the supporting cross beams 21, the support area can be increased, thereby further improving the stability of support for the multiple inner frames 30. When the supporting cross beams 21 are H-shaped steel, T-shaped steel, I-shaped steel, or square steel, stress relief holes are provided in the steel web to reduce stress distortion in the supporting cross beams 21.

[0028] The length direction of the supporting cross beam 21 may be parallel to the width direction W of the outer frame 10. The number of supporting cross beams 21 may be one or more. When there are multiple supporting cross beams 21, the multiple supporting cross beams 21 are arranged at intervals along the depth direction D of the outer frame 10. Both ends of each supporting longitudinal beam 21 are fixedly connected to both ends of the width direction W of the bottom of the outer frame 10. Furthermore, when multiple supporting cross beams 21 are included, the multiple supporting cross beams 21 may be installed parallel to each other along the width direction W of the outer frame 10.

[0029] Optionally, in accordance with the above-mentioned plurality of inner frames 30 dividing the accommodation space into an electrical compartment and a plurality of battery compartments, as shown in Figure 4 or 5, the supporting cross beam 21 has a notch 211 located below the electrical compartment, and a relief portion 212 is formed on one side of the notch 211 that is away from the bottom of the outer frame 10. In this way, the relief portion 212 formed in the notch step 211 makes the bottom surface of the electrical compartment lower than the bottom surface of the battery compartment, making it easier for the ventilation pipe installed below the battery compartment to extend linearly to the electrical compartment, thereby facilitating the installation of electrical devices in the electrical compartment.

[0030] In still other embodiments, as shown in Fig. 4 or 5, the support beam assembly 20 includes a support cross beam 21 and a plurality of support longitudinal beams 22. The installation manner of the support cross beam 21 and the plurality of support longitudinal beams 22 can refer to the installation of the support cross beam 21 and the installation of the plurality of support longitudinal beams 22 described in each of the above two embodiments.

[0031] The supporting cross beams 21 are connected to a plurality of supporting longitudinal beams 22. Each inner frame 30 may be supported by a corresponding supporting longitudinal beam 22, or all of the inner frames 30 may be supported by a supporting cross beam 21, or each inner frame 30 may be supported by a supporting cross beam 21 and a corresponding supporting longitudinal beam 22. The present application is not limited thereto.

[0032] In some embodiments, the supporting cross beam 21 has a plurality of through holes. Each of the supporting longitudinal beams 22 is inserted through a corresponding through hole and fixedly connected to the outer frame 10. In this way, the through holes provided in the supporting cross beam 21 allow the supporting longitudinal beam 22 to be fixedly connected to both ends of the outer frame 10 in the depth direction D without destroying the overall structure of the supporting longitudinal beam 22, thereby further ensuring the structural stability of the supporting beam assembly 20.

[0033] The plurality of through holes are distributed along the length of the supporting cross beam 21. The number of through holes may be the same as or greater than the number of the supporting longitudinal beams 22. When the number of through holes is greater than the number of the supporting longitudinal beams 22, the through holes through which the supporting longitudinal beams 22 are not inserted can be used as stress relief holes for the supporting cross beams 21.

[0034] After the supporting longitudinal beams 22 are inserted through the through holes, the supporting longitudinal beams 22 may be supported by the hole walls of the through holes, or the supporting longitudinal beams 22 may be supported by the hole walls of the through holes and then fixedly connected to the supporting horizontal beams 21. In this way, an integral structure is formed between the supporting horizontal beams 21 and the plurality of supporting vertical beams 22, which further ensures the structural stability of the supporting longitudinal beams 22.

[0035] Taking the example of a case where the number of supporting cross beams 21 provided in the support beam assembly 20 is one, both ends of each of the multiple supporting longitudinal beams 22 are installed symmetrically with respect to the supporting cross beam 21. In this way, the symmetrical installation of both ends of the supporting longitudinal beams 22 ensures uniformity of the torque applied to the supporting longitudinal beams 22, and as a result, further ensures stability of the support of the inner frame 30 by the supporting longitudinal beams 22.

[0036] In some other embodiments, the number of the supporting cross beams 21 may be one or more. In this case, each of the supporting longitudinal beams 22 can be divided into a plurality of sub-supporting longitudinal beams 22 based on the number of the supporting cross beams 21. This allows the fixed connection between each of the supporting longitudinal beams 22 and both ends of the outer frame 10 in the depth direction D without destroying the structure of the supporting cross beams 21.

[0037] As shown in FIG. 4 , there is one supporting cross beam 21. In this case, among the multiple supporting longitudinal beams 22, each supporting longitudinal beam 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 each supporting longitudinal beam 22 are installed symmetrically on both sides of the supporting cross beam 21. A first end of the first sub-longitudinal beam 221 and a first end of the second sub-longitudinal beam 222 are both fixedly connected to the supporting cross beam 21. A second end of the first sub-longitudinal beam 221 and a second end of the second sub-longitudinal beam 222 are fixedly connected to both ends of the outer frame 10 in the depth direction, respectively. In this manner, by installing the first sub-longitudinal beam 221 and the second sub-longitudinal beam 222, one end of the first sub-longitudinal beam 221 is fixedly connected to one side of the supporting cross beam 21, the other end of the first sub-longitudinal beam 221 is fixedly connected to one end in the depth direction of the outer frame 10, one end of the second sub-longitudinal beam 222 is fixedly connected to the other side of the supporting cross beam 21, and the other end of the second sub-longitudinal beam 222 is fixedly connected to the other end in the depth direction of the outer frame 10. This makes it possible to install a plurality of supporting vertical beams 22 without destroying the structure of the supporting cross beam 21 itself, ensuring the structural stability of the supporting cross beam 21 and, as a result, the structural stability of the energy storage container 100.

[0038] Alternatively, when the supporting longitudinal beams 22 include a first sub-longitudinal beam 221 and a second sub-longitudinal beam 222, support for the inner frame 30 is formed on one side of the corresponding supporting longitudinal beam 22. That is, the bottom of the inner frame 30 is supported by and fixedly connected to the first sub-longitudinal beam 221 of the corresponding supporting longitudinal beam 22, or the bottom of the inner frame 30 is supported by and fixedly connected to the second sub-longitudinal beam 222 of the corresponding supporting longitudinal beam 22, or the inner frame 30 is supported by both sides of the corresponding supporting longitudinal beam 22, That is, the bottom of the inner frame 30 is supported by the first and second sub-longitudinal beams 221 and 222 of the supporting longitudinal beam 22, and the first sub-longitudinal beam 221 is fixedly connected to the second sub-longitudinal beam 222.

[0039] In the above embodiment, an example was shown in which there was one supporting cross beam 21. Next, a description will be given of a case in which there are three supporting cross beams 21. As shown in Fig. 6 or 7, the support beam assembly 20 includes three supporting cross beams 21. The three supporting cross beams 21 are arranged along the depth direction D of the outer frame 10. Both ends of each supporting cross beam 21 are fixedly connected to both ends of the outer frame 10 in the width direction W, and the inner frame 30 is supported by the supporting cross beam 21 located at the middle position and is fixedly connected to the two supporting cross beams 21 on both sides.

[0040] Alternatively, as shown in FIG. 6 or 7, three supporting cross beams 21 may be connected by a plurality of supporting longitudinal beams 22 to form an integrated structure. With the three supporting cross beams 21 provided, the bottom of the inner frame 30 may be simultaneously supported by the three supporting cross beams 21 and fixedly connected to the supporting cross beams 21 located on both sides. In this way, the supporting cross beams 21 located on both sides can not only provide support to the inner frame 30, but also be fixed to the inner frame 30. Furthermore, this structure makes it easier to support the inner frame 30 at the same height with the three supporting cross beams 21. The space between two adjacent supporting cross beams 21 is convenient for forming a cable or ventilation passage.

[0041] In some embodiments, as shown in FIG. 8 or 9 , among the multiple inner frames 30, each inner frame 30 includes a pair of vertical beams 31 and a plurality of connecting longitudinal beams 32. The pair of vertical beams 31 are parallel to each other, and the base ends of the vertical beams 31 are supported by the support beam assembly 20. The tip ends of the vertical beams 31 are fixedly connected to the outer frame 10. A plurality of battery holders 40 are fixed to the pair of vertical beams 31. The plurality of connecting longitudinal beams 32 are arranged at intervals along the extension direction of the vertical beams 31. Both ends of each connecting longitudinal beam 32 are fixedly connected to one pair of vertical beams 31. By connecting the pair of vertical beams 31 and the plurality of connecting longitudinal beams 32 to each other in this way to form the inner frame 30, the structural stability of the inner frame 30 can be improved, and thus the stability of fixing the battery holders 40 to the inner frame 30 can be improved.

[0042] The vertical beams 31 according to the present application are beams installed along the height direction H of the outer frame 10. The vertical beams here include not only the vertical beams 31 of the inner frame 30 but also the reinforcing vertical beams 33 of the inner frame 30 described below.

[0043] In light of the above description of the support beam assembly 20, when the support beam assembly 20 includes a plurality of longitudinal support beams 22, the base ends of the vertical beams 31 are supported by the longitudinal support beams 22 corresponding to the inner frame 30 including the vertical beams 31. When the support beam assembly 20 includes a plurality of horizontal support beams 21 (for example, three horizontal support beams 21), each pair of vertical beams 31 is supported by two horizontal support beams 21 located on either side.

[0044] Alternatively, since one pair of vertical beams 31 and multiple connecting vertical beams 32 are located on the same plane, the space occupied by the inner frame 30 in the width direction W of the outer frame 10 can be reduced. This can improve the arrangement density of the inner frame 30. Alternatively, both ends of the multiple connecting vertical beams 32 in the extension direction protrude from one pair of vertical beams 31 in the width direction of the outer frame 10. Each of the multiple connecting vertical beams 32 supports a battery holder 40. In this way, the battery holder 40 is supported by the portions of the connecting vertical beams 32 that protrude from the vertical beams 31, which further improves the support force of the battery holder 40 and thereby prevents bending deformation of the battery holder 40 after the batteries are fixed.

[0045] In some embodiments, as shown in Fig. 8 or 9, among the multiple inner frames 30, each inner frame 30 further includes at least one reinforcing vertical beam 33. The at least one reinforcing vertical beam 33 is located between a pair of vertical beams 31, and the at least one reinforcing vertical beam 33 is fixedly connected to the multiple connecting longitudinal beams 32. In this way, by installing the at least one reinforcing vertical beam 33, the structural stability of the inner frame 30 is further improved.

[0046] Alternatively, in the width direction W of the outer frame 10, the surfaces of the vertical beams 31, the reinforcing vertical beams 33, and the connecting longitudinal beams 32 on the same side may be positioned on the same plane, thereby reducing the space occupied by the inner frame 30 in the width direction W of the outer frame 10. This improves the arrangement density of the inner frame 30. Alternatively, in the width direction of the outer frame 10, the multiple connecting longitudinal beams 32 extend beyond at least one reinforcing vertical beam 33, and both ends of the multiple connecting longitudinal beams 32 in the extension direction protrude from a pair of vertical beams 31. In this way, the protruding portions of the connecting longitudinal beams 32 support the battery holders 40, further improving the support force of the battery holders 40 and thereby preventing bending deformation of the battery holders 40 after the batteries are fixed.

[0047] In some embodiments, of the multiple connecting longitudinal beams 32, one connecting longitudinal beam 32 that is close to the base end of the vertical beam 31 is supported by the support beam assembly 20. In this way, since the connecting longitudinal beam 32 of the inner frame 30 is supported by the support beam assembly 20, the stability of the support of the support beam assembly 20 to the inner frame 30 is further improved, and as a result, the structural stability of the energy storage container 100 is improved.

[0048] In addition to the above description of the support beam assembly 20, when the support beam assembly 20 includes a plurality of longitudinal supporting beams 22, one of the plurality of longitudinal connecting beams 32 that is closest to the base end of the vertical beam 31 is entirely supported by one longitudinal supporting beam 22 that corresponds to the inner frame 30 including that longitudinal connecting beam 32. Regarding the base end of the vertical beam 31 being supported by the longitudinal supporting beam 22, the size of the vertical beam 31 may be larger than the size of the longitudinal supporting beam 22 in the width direction W of the outer frame 10. In this case, to ensure that the longitudinal supporting beam 22 can fully support the base end of the vertical beam 31, protrusions are provided on both sides of the longitudinal supporting beam 22 in the width direction W of the outer frame 10. This increases the support area of ​​the longitudinal supporting beam 22 with respect to the vertical beam 31.

[0049] When the support beam assembly 20 includes the supporting cross beam 21, one of the multiple connecting longitudinal beams 32 that is closest to the base end of the vertical beam 31 intersects with the supporting cross beam 21 and is supported by the supporting cross beam 21. Since the first end of the vertical beam 31 is fixedly connected to the supporting cross beam 21 and the supporting cross beam 21 extends along the width direction W of the outer frame 10, it is ensured that the first end of the vertical beam 31 is completely supported by the supporting cross beam 21 in the width direction W of the outer frame 10.

[0050] In some embodiments, when one battery accommodating position is formed by a pair of battery holders 40, the battery is accommodated in the battery accommodating position through an entrance on one side of the outer frame 10 in the depth direction D. Alternatively, as shown in FIG. 1 , when two battery accommodating positions are formed by a pair of battery holders 40, two batteries are accommodated in the battery accommodating positions through entrances on both sides of the outer frame 10 in the depth direction D (i.e., the two entrances are facing each other). To install two battery accommodating positions corresponding to the two facing entrances, the design of the energy storage container 100 can be reproduced in the depth direction D of the outer frame 10. In this way, not only can the energy capacity of the energy storage container 100 be increased, but the design difficulty of the energy storage container 100 can be simplified while still achieving the increased energy capacity.

[0051] The battery holder 40 is mainly used to mount and fix the battery 50. For the specific structure of the battery holder 40, reference can be made to the related art. Of course, the present application also provides a battery holder 40.

[0052] As shown in FIGS. 10 and 11 , the battery holder 40 includes a support member 41 and a position limiting assembly 42. The support member 41 has a mounting surface 411. The mounting surface 411 has a first mounting area 4111 and a second mounting area 4112 distributed along its length. The first mounting area 4111 is used to mount a first battery 51, and the second mounting area 4112 is used to mount a second battery 52. ​​The position limiting assembly 42 is attached to the support member 41 and is located between the first mounting area 4111 and the second mounting area 4112. The position limiting assembly 42 limits the position of the first battery 51 mounted in the first mounting area 4111 and the position of the second battery 52 mounted in the second mounting area 4112.

[0053] In an embodiment of the present application, as shown in Figures 10 and 11, when a battery is fixed to a battery bracket formed by a pair of battery holders 40, the first mounting area 4111 and the second mounting area 4112 of the support member 41 can mount a first battery 51 and a second battery 52, respectively, thereby improving the battery arrangement density and making it easier to improve the energy capacity of the energy storage device using this battery holder 40.

[0054] In some embodiments, the battery holder 40 further includes a first elastic member and a second elastic member, the first elastic member being fixed to one side of the position limiting assembly 42 facing the first mounting area 4111, and the second elastic member being fixed to one side of the position limiting assembly 42 facing the second mounting area 4112.

[0055] By providing the first elastic member and the second elastic member in this manner, when the first battery 51 and the second battery 52 are inserted into the first mounting area 4111 and the second mounting area 4112, respectively, the elastic cushioning of the first elastic member and the second elastic member prevents strong contact between the inserted first battery 51 and second battery 52 and the position limiting assembly 42. This improves safety when fastening the first battery 51 and the second battery 52, reduces vibration to the fastened first battery 51 and second battery 52, and further ensures stability in fastening the batteries.

[0056] The first elastic member and the second elastic member may have the same structure or different structures. Taking the first elastic member as an example, the first elastic member may be a compression spring, a rubber pad, etc.

[0057] 12 and 13 , the position limiting assembly 42 includes a release mechanism 43 and a position limiting mechanism 44. The release mechanism 43 is fixed to the support member 41 and is used to divide the mounting surface 411 into a first mounting area 4111 and a second mounting area 4112. The position limiting mechanism 44 is fixed to the release mechanism 43 and includes a first position limiting portion 441 facing the first mounting area 4111 and a second position limiting portion 442 facing the second mounting area 4112. The first position limiting portion 441 is used to insert a positioning portion of the first battery 51 to be mounted in the first mounting area 4111. The second position limiting portion 442 is used to insert a positioning portion of the second battery 52 to be mounted in the second mounting area 4112.

[0058] The release mechanism 43 not only separates the mounting surface 411 but also limits the position of the rear ends of the batteries to ensure the depth to which the first battery 51 and the second battery 52 are inserted into the first mounting area 4111 and the second mounting area 4112, respectively. The positioning portion at the rear end of the first battery 51 and the positioning portion at the rear end of the second battery 52 may both have a recessed structure. In this way, when the first position limiting portion 441 is inserted into the positioning portion at the rear end of the first battery 51 and the second position limiting portion 442 is inserted into the positioning portion at the rear end of the second battery 52, the positioning of the first battery 51 and the second battery 52 can be limited in multiple directions. This improves the stability of the fixation of the first battery 51 and the second battery 52.

[0059] The position limiting assembly 42 may be a structure including the above-described release mechanism 43 and position limiting mechanism 44, or may have another structure as long as it can limit the position of the first battery 51 mounted in the first mounting area 4111 and the position of the second battery 52 mounted in the second mounting area 4112. The embodiment of the present application is not limited thereto. For example, the position limiting assembly 42 may be a T-shaped nail.

[0060] 12 , the release mechanism 43 includes a first baffle 431 and a second baffle 432. Both the first baffle 431 and the second baffle 432 are fixedly connected to the support member 41. The first baffle 431 and the second baffle 432 are spaced apart. The first baffle 431 is located at a first end of the first mounting area 4111 (i.e., the end closer to the position limiting assembly 42), and the second baffle 432 is located at a first end of the second mounting area 4112 (i.e., the end closer to the position limiting assembly 42). In this way, the first baffle 431 can stop the rear end of the first battery 51 mounted in the first mounting area 4111, restricting the position of the first battery 51, and the second baffle 432 can stop the rear end of the second battery 52 mounted in the second mounting area 4112, restricting the position of the second battery 52. ​​This allows adjustment of the insertion depth of the first battery 51 and second battery 52.

[0061] When the above-mentioned battery holder 40 further includes a first elastic member and a second elastic member, the first elastic member is fixed to one side of the first baffle 431 facing the first mounting area 4111, and the second elastic member is fixed to one side of the second baffle 432 facing the second mounting area 4112.

[0062] Optionally, the first baffle 431 and the second baffle 432 are both fixed to the support member 41 by welding or by other methods. The embodiment of the present application is not limited thereto.

[0063] Optionally, the support member 41 has positioning grooves corresponding to the first baffle 431 and the second baffle 432. The provision of these positioning grooves makes it easy to determine the fixing 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.

[0064] 14 and 15, the mounting surface 411 of the support member 41 has a first positioning groove 4123 and a second positioning groove 4124. The first positioning groove 4123 determines the positioning on the first baffle 431, and the second positioning groove 4124 determines the positioning on the second baffle 432.

[0065] 12 and 15 , the detachment mechanism 43 further includes a connecting plate 433 located between the first baffle 431 and the second baffle 432. Along the length direction of the support member 41, one end of the connecting plate 433 is fixedly connected to the first baffle 431, and the other end of the connecting plate 433 is fixedly connected to the second baffle 432. At least one of the first baffle 431, the second baffle 432, and the connecting plate 433 is fixedly connected to the support member 41.

[0066] The first baffle 431 and the second baffle 432 are connected by the connecting plate 433 to form an integrated structure, which reduces the number of structural members required for the battery holder 40. Furthermore, because the first baffle 431 and the second baffle 432 have an integrated structure, it is sufficient that at least one of the first baffle 431, the second baffle 432, and the connecting plate 433 is fixedly connected to the support member 41. This further improves the fixing efficiency of the release mechanism 43.

[0067] 12 or 15, the position limiting mechanism 44 includes a position limiting rod (not shown). The position limiting rod is fixedly connected to the release mechanism 43. The position limiting rod passes through the release mechanism 43, and both ends of the position limiting rod protrude from the release mechanism 43 to form a first position limiting portion 441 and a second position limiting portion 442.

[0068] In this way, the two ends of the position limiting rod can respectively form the first position limiting portion 441 and the second position limiting portion 442. One end of the position limiting rod is linked to the positioning hole at the rear end of the first battery 51, and the other end of the position limiting rod is linked to the positioning hole at the rear end of the second battery 52, thereby realizing positional restrictions on the first battery 51 and the second battery 52 in multiple directions. Furthermore, because the first position limiting portion 441 and the second position limiting portion 442 can be formed with a single position limiting rod, the number of structural parts provided in the battery holder 40 can be reduced.

[0069] Optionally, the ends of the first position limiting portion 441 and the second position limiting portion 442 both have a cone-shaped structure. In this way, the cross-sectional areas of the ends of the two position limiting portions can be reduced, which makes it easier to insert the first position limiting portion 441 into the positioning portion at the rear end of the first battery 51 and the second position limiting portion 442 into the positioning portion at the rear end of the second battery 52. ​​Furthermore, the guide function of the slope of the cone-shaped structure makes it possible for the first position limiting portion 441 to quickly limit the position of the first battery 51 and for the second position limiting portion 442 to quickly limit the position of the second battery 52.

[0070] The ends of the first position limiting portion 441 and the second position limiting portion 442 may be conical or pyramidal. The specific shape can be determined by the cross section of the position limiting bar. For example, if the cross section of the position limiting bar is circular, the ends of the first position limiting portion 441 and the second position limiting portion 442 will be conical; if the cross section of the position limiting bar is elliptical, the ends of the first position limiting portion 441 and the second position limiting portion 442 will be elliptical conical; or if the cross section of the position limiting bar is rectangular, the ends of the first position limiting portion 441 and the second position limiting portion 442 will be pyramidal.

[0071] In some other embodiments, the above-described release mechanism 43 includes a first baffle 431 and a second baffle 432, and the position limiting mechanism 44 includes a first protrusion formed on one side of the first baffle 431 facing the first mounting area 4111, and a second protrusion formed on one side of the second baffle 432 facing the second mounting area 4112. The first protrusion forms a first position limiting portion 441, and the second protrusion forms a second position limiting portion 442.

[0072] In this way, the first protrusion and the second protrusion form two position limiting portions of the position limiting mechanism 44. The first protrusion cooperates with the positioning hole at the rear end of the first battery 51, and the second protrusion cooperates with the positioning hole at the rear end of the second battery 52, thereby realizing positional restriction of the first battery 51 and the second battery 52 in multiple directions.

[0073] Alternatively, the first protrusion and the second protrusion may both be pyramidal protrusions, such as conical protrusions or pyramidal protrusions, and the edges of the end faces of the first protrusion and the second protrusion that are away from the release mechanism 43 are provided with rounded chamfers.

[0074] In the above-described battery holder 40, which includes a first elastic member and a second elastic member, both the first elastic member and the second elastic member are compression springs. The first elastic member is sleeved onto a first position limiting portion 441 of the position limiting mechanism 44, and the first position limiting portion 441 protrudes from the first elastic member, or the first elastic member protrudes from the first position limiting portion 441. The second elastic member is sleeved onto a second position limiting portion 442 of the position limiting mechanism 44, and the second position limiting portion 442 protrudes from the second elastic member, or the second elastic member protrudes from the second position limiting portion 442.

[0075] Taking the first elastic member as an example, if the first position limiting portion 441 protrudes beyond the first elastic member, when the first battery 51 is inserted into the first mounting area 4111, the positioning portion at the rear end of the first battery 51 first acts to limit the position and interacts with the first position limiting portion 441. This allows the guide of the first position limiting portion 441 to compress the first elastic member, preventing bending deformation of the first elastic member. If the first elastic member protrudes beyond the first position limiting portion 441, when the first battery 51 is inserted into the first mounting area 4111, the rear end of the first battery 51 first comes into contact with the first elastic member. Therefore, the buffering effect of the first elastic member prevents strong contact between the first position limiting portion 441 and the rear end of the first battery 51 when the positioning portion at the rear end of the first battery 51 is misaligned with the first position limiting portion 441. This improves the safety of the first battery 51.

[0076] In the embodiment of the present application, the support member 41 may have a long, planar structure, or its cross section may have an L-shaped structure, a T-shaped structure, or the like, as long as it is capable of forming the mounting surface 411.

[0077] 10 or 14, the cross section of the support member 41 has an L-shaped structure, and the support member 41 further includes a position limiting surface 412. The position limiting surface 412 intersects with the mounting surface 411 and extends in the longitudinal direction of the mounting surface 411.

[0078] The angle formed between the position limiting surface 412 and the mounting surface 411 may be an acute angle, an obtuse angle, or of course a right angle. When the position limiting surface 412 is perpendicular to the mounting surface 411, the contact area between the position limiting surface 412 and the battery can be increased, thereby improving the position limiting effect on the battery.

[0079] The above-described release mechanism 43 includes a first baffle 431 and a second baffle 432, and the first baffle 431 and the second baffle 432 are fixed to the mounting surface 411 of the support member 41, or are fixed to the position limiting surface 412 of the support member 41, or are fixed simultaneously to both the mounting surface 411 and the position limiting surface 412 of the support member 41. When the first baffle 431 and the second baffle 432 are fixed simultaneously to both the mounting surface 411 and the position limiting surface 412, both the mounting surface 411 and the position limiting surface 412 have a first positioning groove 4123 corresponding to the first baffle 431 and a second positioning groove 4124 corresponding to the second baffle 432. In this way, by providing the two first positioning grooves 4123 and the two second positioning grooves 4124, the stability of pre-fixing the first baffle 431 and the second baffle 432 is further improved.

[0080] 15 , the position limiting surface 412 includes a first guide surface 413 and a second guide surface 414. The first guide surface 413 is located on one side of the position limiting assembly 42 closer to the first mounting area 4111. The extension direction of the first guide surface 413 away from the position limiting assembly 42 forms an acute angle with the length direction of the first mounting area 4111 away from the second mounting area 4112. The second guide surface 414 is located on one side of the position limiting assembly 42 closer to the second mounting area 4112. The extension direction of the second guide surface 414 away from the position limiting assembly 42 forms an acute angle with the length direction of the second mounting area 4112 away from the first mounting area 4111.

[0081] The first guide surface 413 has a first side edge closer to the position limiting assembly 42 and a second side edge farther from the position limiting assembly 42. In the width direction of the mounting surface 411, the second side edge is located between the first side edge and the position limiting assembly 42. The second guide surface 414 has a third side edge closer to the position limiting assembly 42 and a fourth side edge farther from the position limiting assembly 42. In the width direction of the mounting surface 411, the fourth side edge is located between the third side edge and the position limiting assembly 42. In this way, when inserting the first battery 51 into the first mounting area 4111, the first guide surface 413 adjusts the position of the first battery 51 in the width direction of the mounting surface 411, making it easier for the positioning portion at the rear end of the first battery 51 to quickly cooperate with the first position limiting portion 441. That is, the positioning portion can be precisely fitted into the first position limiting portion 441, thereby improving the efficiency of fixing the battery 50.

[0082] Optionally, both the first guide surface 413 and the second guide surface 414 are perpendicular to the mounting surface 411. In this way, when the first guide surface 413 guides the first battery 51 inserted into the first mounting area 4111 and the second guide surface 414 guides the second battery 52 inserted into the second mounting area 4112, 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 preventing wear on the side walls of the first battery 51 by the first guide surface 413 and wear on the side walls of the second battery 52 by the second guide surface 414.

[0083] In some embodiments, in addition to the above-described L-shaped cross section of the support member 41, as shown in FIG. 15 , the position limiting surface 412 has a first bent portion 4121 and a second bent portion 4122. The first bent portion 4121 is located on one side of the position limiting assembly 42 closer to the first mounting area 4111. The second bent portion 4122 is located on one side of the position limiting assembly 42 closer to the second mounting area 4112. In this manner, the first guide surface 413 is formed by the region of the position limiting surface 412 located at the first bent portion 4121, and the second guide surface 414 is formed by the region of the position limiting surface 412 located at the second bent portion 4122. This avoids the need to add a structural member for adjusting the position of the battery in the width direction of the mounting surface 411, thereby simplifying the structure of the support member 41.

[0084] The position limiting surface 412 has the first bent portion 4121 and the second bent portion 4122, and includes a broken notch at a position corresponding to the position limiting assembly 42 in the position limiting surface 412. This makes it easy to form the first bent portion 4121 and the second bent portion 4122 on both sides of the notch, respectively.

[0085] In some other embodiments, the support member 41 includes a first guide block and a second guide block. The first guide block is fixed to the position limiting surface 412 and is located on one side of the position limiting assembly 42 closer to the first mounting area 4111. In a direction closer to the position limiting assembly 42, the surface of the first guide block facing away from the position limiting surface 412 is inclined in a direction away from the position limiting surface 412. The second guide block is fixed to the position limiting surface 412 and is located on one side of the position limiting assembly 42 closer to the second mounting area 4112. In a direction closer to the position limiting assembly 42, the surface of the second guide block facing away from the position limiting surface 412 is inclined in a direction away from the position limiting surface 412. In this way, the surface of the first guide block away from the position limiting surface 412 forms the first guide surface 413, and the surface of the second guide block away from the position limiting surface 412 forms the second guide surface 414, thereby making it possible to adjust the position of the battery in the width direction of the mounting surface 411 and avoiding destroying the structure of the position limiting surface 412.

[0086] Alternatively, the first guide block may be a right-angled trapezoidal block. In this case, the side surface on which the inclined side of the right-angled trapezoidal block is located is formed as the first guide surface 413. Alternatively, the first guide block may be a right-angled triangular block. In this case, the side surface on which the inclined side of the right-angled triangular block is located is formed as the first guide surface 413.

[0087] 16 and 17 , the mounting surface 411 includes a first fixing portion 4113 connected to a second end (one end remote from the positioning assembly 42) of the first mounting area 4111 and a second fixing portion 4114 connected to a second end (one end remote from the positioning assembly 42) of the second mounting area 4112. The first fixing portion 4113 is used to fixedly connect to the first battery 51 mounted in the first mounting area 4111, and the second fixing portion 4114 is used to fixedly connect to the second battery 52 mounted in the second mounting area 4112.

[0088] Both first fixing portion 4113 and second fixing portion 4114 are end structures in the length direction of mounting surface 411, which prevents the battery from occupying a large space in the width direction of mounting surface 411. This improves the space utilization efficiency.

[0089] The first fixing portion 4113 and the second fixing portion 4114 each have a fixing hole 4115 that penetrates the mounting surface 411. An attachment hole is provided at the front end of each of the first battery 51 and the second battery 52. ​​After aligning the fixing hole 4115 of the first fixing portion 4113 with the attachment hole of the first battery 51 to be mounted in the first mounting area 4111 (i.e., after they are aligned in the direction perpendicular to the mounting surface 411), the front end of the first battery 51 is secured by locking with a locking bolt. After aligning the fixing hole 4115 of the second fixing portion 4114 with the attachment hole of the second battery 52 to be mounted in the second mounting area 4112 (i.e., after they are aligned in the direction perpendicular to the mounting surface 411), the front end of the second battery 52 is secured by locking with a locking bolt.

[0090] As shown in FIG. 17 , the front end of the battery has a fixing plate 53, which has an attachment hole. When the battery is fixed to the corresponding mounting area, the fixing plate 53 comes into close contact with the mounting surface 411. In this way, the stability of fixing the front end of the battery is improved. Furthermore, when fixing the front end of the battery to the fixing part, by combining this with the position restriction on the rear end of the battery by the release mechanism 43, it becomes easier to align the fixing hole 4115 of the fixing part with the attachment hole of the fixing plate 53, thereby improving the efficiency of fixing the front end of the battery.

[0091] Of course, in addition to opening the fixing holes 4115 in the first fixing portion 4113 and the second fixing portion 4114 to fix the front end of the battery, other methods for fixing the front end of the battery can also be used, and the embodiments of the present application are not limited thereto.

[0092] 14 or 16, the battery holder 40 further includes a reinforcing rib 45. The reinforcing rib 45 is fixed to one side of the support member 41 that is away from the mounting surface 411.

[0093] When the battery holder 40 is fixed to the fixed frame, the reinforcing ribs 45 are also fixedly connected to the fixed frame. In this way, the support provided by the reinforcing ribs 45 improves the strength with which the first mounting area 4111 and the second mounting area 4112 of the support member 41 support the battery, preventing deformation of the support member 41 due to load.

[0094] The reinforcing rib 45 may be an integral structure. That is, the reinforcing rib 45 may be a rectangular structure extending in the length direction of the support member 41. In this case, the cross section of the reinforcing rib 45 may be a triangle, a right-angled trapezoid, or the like. Alternatively, the reinforcing rib 45 may include a plurality of reinforcing blocks distributed in the length direction of the support member 41. When viewed in the length direction of the support member 41, the reinforcing blocks may have a triangular or right-angled trapezoidal shape. When viewed in the width direction of the support member 41, the reinforcing blocks may have an I-shape, an L-shape, a T-shape, or the like. This is not a limitation in the embodiments of the present application. It is sufficient that the first mounting area 4111 and the second mounting area 4112 of the support member 41 can enhance the strength to support the battery.

[0095] An embodiment of the present application further provides an electric device, which may be an energy storage device, a vehicle, etc. The electric device includes the energy storage container 100 described in the above embodiment. In this way, in combination with the above description, it is easy to ensure the stability of the energy storage container 100 during use of the electric device of the present application, thereby improving the safety of use of the electric device.
