[0039] It should be further understood that the term " / and / " used in this specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0040] Please refer to Figures 1-10 A household energy storage device provided by an embodiment of the present invention includes an energy storage box 10, and a module box 20 is arranged inside the energy storage box 10; the module box 20 includes a surrounding plate 21 and a sealing plate 22, the surrounding plate 21 encloses to form a receiving space 211 with a through top, and the receiving space 211 is used to receive the battery 31 module 30, the battery 31 module 30 includes a plurality of batteries 31 arranged along the length direction of the receiving space 211; wherein, the receiving space 211 has an open end 212, and the sealing plate 22 is arranged at the open end 212 and can move relative to the surrounding plate 21 along the length direction of the receiving space 211, so that the sealing plate 22 abuts against the battery 31 module 30 and is fixedly connected to the surrounding plate 21.

[0041] In this embodiment, the household energy storage device includes an energy storage box 10, and a module box 20 for accommodating and fixing the battery 31 module 30 is arranged inside the energy storage box 10. The structure of the module box 20 includes two main parts, namely a surrounding plate 21 and a sealing plate 22, wherein the surrounding plate 21 encloses to form a receiving space 211 for accommodating the battery 31 module 30. A plurality of batteries 31 are arranged along the length direction of the receiving space 211, and these batteries 31 are arranged in sequence to form a complete battery 31 module 30.

[0042] During specific implementation, the top of the receiving space 211 is through upward, and the battery 31 can be directly placed into the receiving space 211 from the top. The receiving space 211 has an open end 212, and the sealing plate 22 is arranged at the open end 212, and its design is that the sealing plate 22 can move relative to the surrounding plate 21 along the length direction of the receiving space 211. The purpose of this moving design is to enable the sealing plate 22 to accurately abut against the battery 31 module 30. By adjusting the position of the sealing plate 22, an appropriate pressure can be applied to the battery 31 module 30, thereby realizing the fixation of the battery 31 module 30. After the sealing plate 22 moves to the appropriate position, it is fixedly connected to the surrounding plate 21, thereby completing the fixation process of the entire battery 31 module 30.

[0043] During the actual installation process, first, the batteries 31 need to be sequentially placed into the receiving space 211 formed by the surrounding plate 21 according to a predetermined arrangement to form a complete battery 31 module 30. Then, the sealing plate 22 is inserted from the open end 212 of the receiving space 211, and the sealing plate 22 is pushed to move along the receiving space 211 towards the battery 31 module 30. When the sealing plate 22 moves to the predetermined position, at this time, the sealing plate 22 will apply an appropriate pressure to the battery 31 module 30, so that two adjacent batteries 31 are closely attached, and then the sealing plate 22 is fixedly connected to the surrounding plate 21. In this way, the battery 31 module 30 can be firmly fixed in the module box 20, effectively avoiding the shaking of the battery 31 during use. After the battery 31 module 30 is fixed, the entire module box 20 is placed into the energy storage box 10 for installation.

[0044] This structural design has the following advantages: First, since the top of the accommodation space 211 is through, the operator can directly place the battery 31 from the top and adjust its position without considering the size limitation of the open end 212, which simplifies the assembly process of the battery 31 module 30 and improves the assembly efficiency. Then, the sealing plate 22 can control the pressure applied to the battery 31 module 30 by moving within the accommodation space 211. Cooperating with the fixed connection with the surrounding plate 21, a complete restraint is formed, avoiding the problems of uneven or excessive pressure caused by the traditional bundling method that may lead to damage, thus realizing reliable fixation of the battery 31 module 30.

[0045] In this embodiment, the predetermined position refers to the final fixed position where the sealing plate 22 moves within the accommodation space 211. Specifically, when the sealing plate 22 moves, it will gradually approach the battery 31 module 30 until an appropriate pressure is generated on the battery 31 module 30. This pressure needs to ensure that the adjacent batteries 31 are closely fitted together, but not cause damage to the battery 31. Usually, the predetermined position can be determined by pre-setting marks on the surrounding plate 21 or using a force measuring device to ensure that the pressure applied by the sealing plate 22 during each installation can be maintained within a suitable range. When the sealing plate 22 moves to this predetermined position, at this time, the sealing plate 22 will apply an appropriate pressure to the battery 31 module 30, making the adjacent two batteries 31 closely fitted together, and then the sealing plate 22 is fixedly connected to the surrounding plate 21.

[0046] In one embodiment, a support tray 40 is provided at the top of the battery 31 module 30. A signal acquisition component is provided on the support tray 40. The signal acquisition component includes an acquisition board 51 and a signal wire harness 52 electrically connected to the acquisition board 51; two first extension parts 41 are provided oppositely at the top of the support tray 40, and an accommodation groove 42 is formed between the first extension parts 41 and the support tray 40, and the signal wire harness 52 is arranged in the adjacent accommodation groove 42.

[0047] In this embodiment, a support tray 40 is provided at the top of the battery 31 module 30. During the assembly process, first, the signal acquisition component is installed on the support tray 40. The main function of the signal acquisition component is to collect and monitor the working state information of the battery 31, and it includes two key parts: the acquisition board 51 and the signal wire harness 52 electrically connected to the acquisition board 51. Among them, the acquisition board 51 is used to collect the working state information of the battery 31, including but not limited to parameters such as the voltage and current of the battery 31. The acquisition board 51 is reserved with positive and negative pole ear interfaces for electrically connecting with the battery 31, and the signal wire harness 52 is responsible for transmitting the signal data acquired by the acquisition board 51.

[0048] A pair of oppositely arranged first extension parts 41 are designed on the top of the support pallet 40, and this design forms a structure for harness arrangement. Specifically, a receiving groove 42 is formed between the first extension part 41 and the support pallet 40, and each signal harness 52 is arranged in the adjacent receiving groove 42. This structural design makes the arrangement of the signal harness 52 more regular and orderly, and also plays a role in protecting the harness.

[0049] During specific implementation, since the signal acquisition component has been pre-installed on the support pallet 40, the operator only needs to cover the entire support pallet 40 on the top of the battery 31 module 30, and then establish an electrical connection with the battery 31 through the reserved tab interface to complete the installation. This pre-assembly method not only simplifies the on-site installation steps and improves the assembly efficiency, but also ensures the standardization of the harness arrangement during the entire installation process because the harness has been fixed in the receiving groove 42.

[0050] The advantages of this design are as follows: First, by adopting the pre-assembly method, the signal acquisition component is pre-installed on the support pallet 40, avoiding the cumbersome process of installing the acquisition board 51 one by one and arranging the harness on-site, and improving the assembly efficiency; Second, the receiving groove 42 formed by the first extension part 41 not only provides a fixed arrangement space for the signal harness 52, but also can prevent the harness from shifting during the overall installation process of the support pallet 40; Third, since the position of the acquisition component has been pre-adjusted and fixed, when the support pallet 40 is covered on the battery 31 module 30, the acquisition board 51 can be aligned with the connection position of the battery 31, and only the electrical connection of the tab needs to be completed, which ensures the reliability and consistency of the installation quality. In addition, this modular design can quickly complete the repair by replacing the entire support pallet 40 component during later maintenance, greatly improving the maintainability of the device.

[0051] In this embodiment, among the two first extension parts 41 on the top of the support pallet 40, each first extension part 41 extends vertically upward from the top surface of the support pallet 40. Specifically, a groove-shaped space is formed between the first extension part 41 and the top surface of the support pallet 40, and this groove-shaped space is the receiving groove 42 for accommodating the signal harness 52. Since the first extension part 41 extends vertically upward, the bottom (one side) of the receiving groove 42 is the top surface of the support pallet 40, and the other side is the outer wall surface of the first extension part 41. This structure forms a semi-closed space, which can effectively accommodate and protect the signal harness 52.

[0052] In one embodiment, a plurality of second extension portions 43 are further provided on the top of the support pallet 40, and the plurality of second extension portions 43 are arranged at intervals along the arrangement direction of the batteries 31; a wire harness channel 44 is formed between two adjacent second extension portions 43, and the wire harness channel 44 is used to accommodate the signal wire harness 52 of the adjacent acquisition board 51.

[0053] In this embodiment, in addition to the first extension portion 41 provided on the top of the support pallet 40, a plurality of second extension portions 43 are also provided. The characteristics of these second extension portions 43 are that they are arranged at intervals along the arrangement direction of the batteries 31. Here, the arrangement direction refers to the arrangement direction of the batteries 31 in the accommodation space 211, that is, the second extension portions 43 are arranged at intervals in sequence along the arrangement direction of the batteries 31. Specifically, a wire harness channel 44 is formed between two adjacent second extension portions 43, and the wire harness channel 44 is used to accommodate the signal wire harness 52 of the adjacent acquisition board 51.

[0054] In specific implementation, since each battery 31 needs to be equipped with an acquisition board 51 for status monitoring, multiple groups of signal wire harnesses 52 will be formed. In order to make these signal wire harnesses 52 distributed in an orderly manner, the second extension portions 43 are arranged according to the following principles: First, the plurality of second extension portions 43 are arranged at intervals in sequence along the arrangement direction of the batteries 31, so that an independent wire harness channel 44 is formed between every two adjacent second extension portions 43; Second, each wire harness channel 44 is specifically used to accommodate the signal wire harness 52 connected to the adjacent acquisition board 51.

[0055] The advantages of this structural design are as follows: First, through the spaced arrangement of the second extension portions 43, a plurality of independent wire harness channels 44 are formed, and the signal wire harness 52 of each acquisition board 51 has its own dedicated arrangement space, avoiding the problem of the wire harnesses of different acquisition boards 51 intersecting or being mixed with each other; Then, this sub-region arrangement method enables the wire harness of each acquisition board 51 to be clearly identified. During later maintenance or fault troubleshooting, the specific wire harness position can be quickly located, improving the maintenance efficiency. Finally, this design fixes the signal wire harness 52 of each acquisition board 51 in the corresponding wire harness channel 44, reducing the possibility of the signal wire harness 52 moving or loosening, thereby ensuring the safety and reliability of the wire harness during use.

[0056] In one embodiment, a separator 60 is provided between the first extension portions 41, and an explosion-proof valve 70 is provided on the top of the battery 31 in the battery 31 module 30, and the explosion-proof valve 70 is located inside the separator 60.

[0057] In this embodiment, a separator 60 is disposed between two first extension portions 41, and the separator 60 is used in cooperation with an explosion-proof valve 70 in the battery 31 module 30. Specifically, an explosion-proof valve 70 is provided on the top of each battery 31 in the battery 31 module 30, and these explosion-proof valves 70 are all located inside the separator 60.

[0058] The separator 60 is installed between two first extension portions 41 to form a protection structure for the explosion-proof valve 70. After the battery 31 module 30 is installed, the explosion-proof valves 70 of all batteries 31 are arranged inside the separator 60, and such an arrangement ensures the safety of the explosion-proof valve 70 during operation.

[0059] The advantages of this structural design are as follows: By providing the separator 60, a dedicated protection space is provided for the explosion-proof valve 70, avoiding external interference or damage to the explosion-proof valve 70 during installation and use; at the same time, when an abnormal situation occurs in the battery 31 and pressure relief is required, the separator 60 can play a guiding role, enabling the pressure relief gas to be discharged in a predetermined direction and avoiding the impact of the pressure relief process on surrounding components.

[0060] In one embodiment, the separator 60 includes: a bottom plate 61 and vertical plates 62 disposed on opposite sides of the bottom plate 61. The vertical plates 62 and the bottom plate 61 enclose an isolation groove 63. The top ends of the vertical plates 62 extend toward the center of the isolation groove 63 to form support portions 64, and there is a gap between the two support portions 64 on both sides; the bottom plate 61 is provided with a plurality of through slots 611, and the plurality of through slots 611 are spaced along the arrangement direction of the batteries 31, and the explosion-proof valves 70 are respectively disposed in the through slots 611.

[0061] In this embodiment, the bottom plate 61 is connected to the support tray 40, and the vertical plates 62 are vertically disposed on opposite sides of the bottom plate 61. An isolation groove 63 is formed between the vertical plates 62 and the bottom plate 61. The top ends of the vertical plates 62 extend inward to a certain extent to form support portions 64 for supporting the components located above. There is a certain gap between the support portions 64 formed by the two vertical plates 62 on both sides, and this gap communicates with the isolation groove 63 and the through slots 611 respectively. The plurality of through slots 611 on the bottom side of the bottom plate 61 are arranged along the arrangement direction of the batteries 31, and the explosion-proof valves 70 are respectively disposed in the corresponding through slots 611.

[0062] This structural design has the following advantages: First, through the combined setting of the bottom plate 61, the vertical plate 62, and the through groove 611, all-round protection of the explosion-proof valve 70 is achieved. The setting of the isolation groove 63 avoids interference between the explosion-proof valve 70 and surrounding components, and at the same time, through the setting of the through groove 611, the normal operation of the explosion-proof valve 70 is ensured; Second, the support portion 64 formed by the inward extension of the top end of the vertical plate 62 provides reliable support for the upper components; Third, the spaced arrangement of the multiple through grooves 611 corresponds to the arrangement direction of the batteries 31, so that each explosion-proof valve 70 can accurately correspond to the corresponding position of the through groove 611, facilitating installation and maintenance.

[0063] In one embodiment, a cushion block 81 and an epoxy board 82 are respectively arranged on the support portion 64. The epoxy board 82 is provided with a plurality of through holes 83. A part of the holes 83 is correspondingly arranged with the cushion block 81, and the cushion block 81 is inserted into the corresponding holes 83. Another part of the holes 83 is correspondingly arranged with the gap between the support portion 64, and the gap is located below the corresponding holes 83.

[0064] In this embodiment, a cushion block 81 and an epoxy board 82 are respectively arranged on the support portion 64, and the epoxy board 82 is designed with a plurality of through holes 83. These holes 83 can be divided into two categories: A part of the holes 83 corresponds to the position of the cushion block 81, and the cushion block 81 is inserted into these corresponding holes 83; Another part of the holes 83 is correspondingly arranged with the gap between the support portion 64, so that the gap is located directly below these corresponding holes 83.

[0065] In specific implementation, the cushion block 81 is arranged on the support portion 64 formed by the inward extension of the top end of the vertical plate 62. The epoxy board 82 is arranged above the support portion 64, and the top surface of the epoxy board 82 is provided with a plurality of through holes 83. A part of the holes 83 corresponds to the position of the cushion block 81, so that the cushion block 81 is inserted into these holes 83. In addition, a cover plate 12 of the energy storage box 10 is arranged above the cushion block 81. In this structural design, the setting of the cushion block 81 ensures a certain gap between the cover plate 12 and the epoxy board 82, which can not only provide sufficient pressure relief space for the battery 31 but also ensure that the gas generated during pressure relief can be effectively guided and discharged.

[0066] The advantages of this design are as follows: First, the cushion block 81 forms a stable support structure by being inserted into the holes 83 of the epoxy board 82, providing reliable support for the cover plate of the energy storage box 10 and preventing the cover plate 12 from being pressed against the epoxy board 82 and other electrical components inside the box body 11 by external forces; Second, while ensuring the support strength, the cushion block 81 also ensures an appropriate gap between the cover plate 12 and the epoxy board 82; Third, the epoxy board 82, as an insulating material, also plays a role in electrical safety protection in the whole structure. The overall structural design not only ensures mechanical strength but also takes into account safety performance.

[0067] In one embodiment, a partition 90 is disposed in the accommodation space 211. The partition 90 divides the accommodation space 211 into a first cavity 91 and a second cavity 92. The battery 31 module 30 includes a first battery 31 module 32 disposed in the first cavity 91 and a second battery 31 module 33 disposed in the second cavity 92.

[0068] In this embodiment, a partition 90 is vertically disposed in the accommodation space 211. The partition 90 divides the accommodation space 211 into a first cavity 91 and a second cavity 92 that are adjacent in the horizontal direction. There are two battery 31 modules 30: a first battery 31 module 32 disposed in the first cavity 91 and a second battery 31 module 33 disposed in the second cavity 92 respectively.

[0069] Specifically, the partition 90 is vertically disposed at the central position of the accommodation space 211, dividing the accommodation space 211 into a first cavity 91 and a second cavity 92 of equal size. During assembly, the first battery 31 module 32 and the second battery 31 module 33 are respectively placed into the corresponding cavities. Then, the sealing plate 22 is inserted into the accommodation space 211 from the open end 212, and the sealing plate 22 is pushed to move along the accommodation space 211 towards the two battery 31 modules 30. When the sealing plate 22 moves to a predetermined position, pressure is applied to the two battery 31 modules 30 simultaneously to fixedly connect the sealing plate 22 to the surrounding plate 21, so that the two battery 31 modules 30 are respectively fixed in the first cavity 91 and the second cavity 92. After that, the entire module box 20 is placed into the energy storage box 10 for installation.

[0070] This design has the following advantages: First, by dividing the accommodation space 211 into two independent cavities through the partition 90, it is convenient to group and manage the battery 31 modules 30; Second, this partitioned design is also convenient for later maintenance. When one of the battery 31 modules 30 needs to be repaired or replaced, it can be processed separately without affecting the other battery 31 module 30.

[0071] In one embodiment, there are two sealing plates 22, which are respectively disposed at opposite ends of the surrounding plate 21. Two embedding grooves 100 are provided at the top of the sealing plates 22. Insulating seats 110 are disposed in the embedding grooves 100. Two ends of the signal acquisition components on the first battery 31 module 32 and the second battery 31 module 33 are respectively fixedly connected to the corresponding insulating seats 110.

[0072] In this embodiment, the surrounding plate 21 has an upward C-shaped structure, and sealing plates 22 are provided at both ends thereof. Two embedding grooves 100 are provided at the top end of each sealing plate 22, and the insulating seats 110 are respectively inserted into the corresponding embedding grooves 100. In specific implementation, each insulating seat 110 is connected to a collecting plate 51 of a battery 31 module 30. Among them, the collecting plate 51 at one end is fixed to the corresponding insulating seat 110 through a second connecting plate 120, and the collecting plate 51 at the other end is fixed to the other insulating seat 110 and is connected to the total positive line 131 and the total negative line 132.

[0073] In one embodiment, the embedding groove 100 includes a connected upper opening 101 and a lower accommodating cavity 102, and the width of the upper opening 101 is smaller than the width of the lower accommodating cavity 102; the insulating seat 110 includes a connected head 111 and a fixing part, and the width of the head 111 is smaller than the width of the fixing part. The head 111 is inserted into the upper opening 101, the fixing part is accommodated in the lower accommodating cavity 102, and there is a height difference between the fixing part and the lower accommodating groove 42.

[0074] In this embodiment, the embedding groove 100 adopts a stepped structure design, including a connected upper opening 101 and a lower accommodating cavity 102, wherein the width of the upper opening 101 is smaller than the width of the lower accommodating cavity 102. Correspondingly, the insulating seat 110 also adopts a matching structure, including a connected head 111 and a limiting part 112, wherein the width of the head 111 is smaller than the width of the limiting part 112. During installation, the head 111 is inserted into the upper opening 101, and the limiting part 112 is accommodated in the lower accommodating cavity 102.

[0075] In specific implementation, this stepped structure design of the embedding groove 100 has a clear functional purpose: the narrower design of the upper opening 101 is used to accurately guide the insertion of the head 111 of the insulating seat 110, while the wider design of the lower accommodating cavity 102 provides a suitable installation space for the limiting part 112. During the installation process, the insulating seat 110 is inserted into the embedding groove 100 from front to back. After the limiting part 112 completely enters the lower accommodating cavity 102, there will be a certain gap between its top surface and the lower accommodating cavity 102. The design of this gap is to ensure that the limiting part 112 has a certain up and down movement space after insertion, so as to adapt to the position changes of the supporting tray 40 and the signal acquisition components thereon due to various factors, improving the flexibility and adaptability of the overall installation.

[0076] The advantages of this structural design are as follows: First, through the stepped structural design, the accurate positioning and installation of the insulating base 110 can be ensured; Second, the size difference between the upper opening 101 and the lower accommodating cavity 102 not only ensures the convenience of installation but also reserves the necessary movement space for the limiting part 112; Third, the gap reserved between the limiting part 112 and the lower accommodating cavity 102 can effectively adapt to the position changes of the support pallet 40 and the signal acquisition component, improving the adaptability of the entire component during the installation process. The overall structural design not only ensures the reliability of installation but also provides the necessary position adjustment margin.
