Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to an energy storage container and an energy storage device. Background Technology

[0002] Containers are generally divided into electrical compartments and battery compartments, separated by a partition. The power and communication lines of the battery clusters are connected from the battery compartment to the combiner cabinet in the electrical compartment. If a partition wall is directly installed, the wiring harnesses need to be fixed to the partition wall in advance, which is not conducive to the adjustment and installation of the wiring harness layout. If the wiring harnesses are laid out first, a hole needs to be drilled in the partition wall to facilitate the wiring harnesses to pass through for installation. In this case, because the hole in the partition wall is large, the battery compartment and the electrical compartment are connected, resulting in poor isolation between the electrical compartment and the battery compartment. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide an energy storage container and energy storage device that facilitates the laying of wiring harnesses and provides a good isolation effect between the second chamber and the first chamber.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] On one hand, an energy storage container is provided, including a container body and a partition. The container body has a cavity, and the partition is disposed within the cavity, dividing the cavity into a first chamber and a second chamber. The partition includes a fixed partition, a movable baffle, and a locking part. The outer periphery of the fixed partition is fixedly connected to the cavity wall of the cavity. The fixed partition has a through hole along its thickness direction for a wire harness to pass through. The movable baffle is movably connected to the fixed partition. The movable baffle can move to the through hole to press the wire harness against the through hole. The movable baffle can be fixed to the fixed partition by the locking part.

[0006] As a further embodiment of the energy storage container, the through hole is located at the edge of the fixed partition, one side of the through hole penetrates the fixed partition to form an opening, and the movable baffle can move toward or away from the opening.

[0007] As a further embodiment of the energy storage container, the through hole is located at the lower edge of the fixed partition, and the opening is located on the lower side of the fixed partition.

[0008] As a further embodiment of the energy storage container, the movable baffle includes a baffle body and a bending portion. The baffle body can be fixedly connected to the fixed partition via the locking portion. The bending portion is connected to the side of the baffle body opposite the opening of the through hole. The bending portion protrudes from one side of the baffle body along its thickness direction. The movable baffle can move toward the opening until the bending portion presses the wire harness against the cavity wall of the cavity.

[0009] As a further embodiment of the energy storage container, the locking part includes multiple bolts and nuts that match the bolts. The baffle body is provided with multiple adjustable elongated holes spaced apart. The adjustable elongated holes penetrate along the thickness direction of the baffle body, and the length of the adjustable elongated holes extends along the moving direction of the movable baffle. The fixed partition is provided with multiple connecting holes adjacent to the through hole. The bolts, the adjustable elongated holes, and the connecting holes correspond one-to-one. The bolts can pass through the adjustable elongated holes and the connecting holes and be locked by the nuts to fix the movable baffle to the fixed partition.

[0010] As a further embodiment of the energy storage container, a wire harness snap-fit ​​device is also included, which is detachably mounted on the cavity wall and offset from the opening of the through hole.

[0011] As a further embodiment of the energy storage container, there are multiple movable baffles arranged sequentially. Each movable baffle can move toward the opening to abut against the cavity wall of the cavity facing the opening, and each movable baffle is selectively locked by a locking part.

[0012] On the other hand, an energy storage device is provided, including a battery, electrical components, wiring harness, and the energy storage container. The battery is installed in a first chamber, the electrical components are installed in a second chamber, the wiring harness passes through a through hole in a fixed partition to connect the battery and the electrical components, and a movable baffle presses the wiring harness against the through hole and locks it in place by the locking part.

[0013] As a further embodiment of the energy storage device, a sealing element is also included, which fills the gap between the movable baffle and the fixed partition, and fills the gap between the movable baffle and the wall of the through hole.

[0014] As a further option for the energy storage device, the sealing element is fireproof putty or sealant.

[0015] Beneficial effects: The separator of this utility model adopts a combination structure design of a fixed partition and a movable baffle, which allows for a sufficiently large through-hole size to facilitate the laying of wire harnesses. Before installing the wire harness, the movable baffle is moved away from the through-hole to make the through-hole large enough for the wire harness to pass through. After the wire harness is laid, the movable baffle is moved closer to the wire harness, pressing the wire harness against the wall of the through-hole, and the movable baffle is fixed to the fixed partition by the locking part to reduce the gap around the wire harness. After the movable baffle is locked and fixed, a sealing component can be used to seal the gap, thereby providing a good isolation effect between the second chamber and the first chamber, and better managing the temperature and humidity of the second and first chambers. When a battery is installed in one of the first and second chambers and electrical components are installed in the other chamber, and the battery experiences thermal runaway, the electrical components in the other chamber can be protected from damage.

Furthermore, the terms "first," "second," etc., are merely used for distinction in description and have no special meaning.

[0028] like Figures 1 to 4As shown, this embodiment provides an energy storage container, including a container body 100 and a partition 200. The container body 100 has a cavity, and the partition 200 is disposed in the cavity, dividing the cavity into a first chamber 110 and a second chamber 120. The partition 200 includes a fixed partition 210, a movable baffle 220 and a locking part 230. The outer periphery of the fixed partition 210 is fixedly connected to the cavity wall of the cavity. The fixed partition 210 has a through hole 2101 along its thickness direction for the wire harness 1 to pass through. The movable baffle 220 is movably connected to the fixed partition 210. The movable baffle 220 can move to the through hole 2101 to press the wire harness 1 against the through hole 2101. The movable baffle 220 can be fixed on the fixed partition 210 by the locking part 230.

[0029] The container 100 includes the container body and the container door. Figure 1 and Figure 2 The energy storage container shown does not have a door. In this embodiment, one of the first chamber 110 and the second chamber 120 serves as a battery compartment for installing batteries, and the other chamber serves as an electrical compartment for installing electrical components. The batteries and electrical components are electrically connected via a wiring harness passing through the through-hole 2101. The following description, using the first chamber 110 for installing batteries and the second chamber 120 for installing electrical components, will further illustrate this embodiment in detail.

[0030] It is understood that the separator 200 in this embodiment adopts a combination structure design of fixed partition 210 and movable baffle 220, which can make the size of the through hole 2101 large enough to facilitate the laying of wire harness 1. Before installing the wiring harness 1, move the movable baffle 220 away from the through hole 2101 to make the through hole 2101 large enough to facilitate the passage of the wiring harness 1. After the wiring harness 1 is laid, move the movable baffle 220 closer to the wiring harness 1 to press the wiring harness 1 against the wall of the through hole 2101. Then, fix the movable baffle 220 to the fixed partition 210 by the locking part 230 to reduce the gap around the wiring harness 1. After the movable baffle 220 is locked and fixed, a sealant can be used to seal the gap, so that the second chamber 120 and the first chamber 110 have a good isolation effect and can better manage the temperature and humidity of the second chamber 120 and the first chamber 110. When the battery experiences thermal runaway, the partition 200 can protect electrical components from damage.

[0031] In other embodiments, the first chamber 110 and the second chamber 120 can also serve as battery compartments for installing batteries. The batteries in the two battery compartments are connected by a wire harness passing through the through hole 2101. The movable baffle 220 presses the wire harness 1 against the wall and then fixes it with the locking part 230. The gap can be sealed by a sealing member, so that the two battery compartments can have a good isolation effect and can better manage the temperature and humidity of the two battery compartments. When the battery in either battery compartment experiences thermal runaway, the separator 200 can protect the battery in the other battery compartment from damage.

[0032] Furthermore, such as Figures 2 to 4 As shown, the through hole 2101 is located at the edge of the fixed partition 210. One side of the through hole 2101 passes through the fixed partition 210 to form an opening. The movable baffle 220 can move towards the opening or away from the opening. The two ends of the movable baffle 220 along its width direction can block the through hole 2101.

[0033] In this embodiment, by designing the through hole 2101 at the edge of the fixed partition 210 and making one side of the through hole 2101 penetrate through the fixed partition 210 to form an opening, the processing difficulty of the through hole 2101 can be reduced, and the wiring harness 1 can be laid out more easily. Before installing the wiring harness 1, the movable baffle 220 is moved away from the opening to make the through hole 2101 large enough to facilitate the passage of the wiring harness 1; after the wiring harness 1 is laid, the movable baffle 220 is moved closer to the opening to press the wiring harness 1 against the cavity wall.

[0034] Furthermore, the via 2101 is located at the lower edge of the fixed partition 210, and the opening is located on the lower side of the fixed partition 210. After the wire harness 1 passes through the via 2101, the cavity wall of the cavity can provide a certain support force for the wire harness 1.

[0035] like Figure 4 As shown, the movable baffle 220 includes a baffle body 221 and a bending portion 222. The baffle body 221 can be fixedly connected to the fixed partition 210 through the locking portion 230. The bending portion 222 is connected to the side of the baffle body 221 facing the opening of the through hole 2101. The bending portion 222 protrudes from one side of the baffle body 221 along its thickness direction. The movable baffle 220 can move toward the opening until the bending portion 222 presses the wire harness 1 against the cavity wall of the cavity.

[0036] In this embodiment, the bending portion 222 is designed on the side of the baffle body 221 facing the opening of the through hole 2101. After the wire harness 1 is laid, the movable baffle 220 moves towards the opening, allowing the bending portion 222 to abut against the wire harness 1, increasing the contact area between the bending portion 222 and the wire harness 1, thereby preventing the movable baffle 220 from scratching the wire harness 1. At the same time, the structural design of the bending portion 222 also increases the structural strength of the movable baffle 220. In addition, when the sealing element is subsequently installed, the contact area between the sealing element and the movable baffle 220 can be increased, thereby improving the sealing stability.

[0037] Furthermore, in this embodiment, the side of the movable baffle 220 facing the opening can be designed as a flexible rubber part (not shown in the figure). The flexible rubber part will deform after it comes into contact with the wire harness 1, which can both reduce the gap around the wire harness 1 and prevent the movable baffle 220 from scratching the wire harness 1.

[0038] In this embodiment, the locking part 230 includes a plurality of bolts 231 and nuts 232 that match the bolts 231. The baffle body 221 is provided with a plurality of adjusting elongated holes 2211 at intervals. The adjusting elongated holes 2211 penetrate along the thickness direction of the baffle body 221, and the length of the adjusting elongated holes 2211 extends along the moving direction of the movable baffle 220. The fixed partition 210 is provided with a plurality of connecting holes adjacent to the through hole 2101. The bolts 231, adjusting elongated holes 2211 and connecting holes correspond one-to-one. The bolts 231 can pass through the adjusting elongated holes 2211 and connecting holes and be locked by the nuts 232 so that the movable baffle 220 is fixedly connected to the fixed partition 210.

[0039] For example, the number of adjustment elongated holes 2211 is two, and the two adjustment elongated holes 2211 are arranged adjacent to the two edges of the baffle body 221. Specifically, as Figure 4 As shown, the thickness of the fixed partition 210 extends along the X direction, the width extends along the Y direction, and the height extends along the Z direction. Therefore, the length of the adjusting elongated hole 2211 extends along the Z direction. This adjusting elongated hole 2211 is located adjacent to the upper side of the baffle body 221. The bolt 231 passes through the adjusting elongated hole 2211 and is screwed into the connecting hole for fixation. After loosening the bolt 231, the movable baffle 220 can be adjusted up and down. After the position of the movable baffle 220 is adjusted, the bolt 231 is tightened to fix the movable baffle 220. During the adjustment of the movable baffle 220, the bolt 231 remains screwed into the connecting hole.

[0040] like Figure 2 and Figure 3 As shown, the energy storage container in this embodiment also includes a wire harness clamping member 300 for clamping the wire harness 1. The wire harness clamping member 300 is detachably installed on the cavity wall and offset from the opening of the through hole 2101. By setting the wire harness clamping member 300, the wire harness 1 can be laid in an orderly manner at the opening position.

[0041] The wire harness connector 300 has multiple spaced slots, and the wire harness 1 can be engaged with these slots.

[0042] Furthermore, there are multiple movable baffles 220, all of which are arranged in sequence. Each movable baffle 220 is selectively locked by a locking part 230. The movable baffle 220 can move toward the opening to abut against the cavity wall of the cavity facing the opening.

[0043] In this embodiment, when the dimension of the through hole 2101 along the width direction of the fixed partition 210 is large, multiple movable baffles 220 can be designed. Each movable baffle 220 can abut against a portion of the wire harness 1. When the open position of the through hole 2101 corresponding to a certain movable baffle 220 is not covered with wire harness 1, the movable baffle 220 can be directly pushed to abut against the cavity wall of the cavity corresponding to the open area, avoiding gaps in that area and simplifying the subsequent sealing process. Therefore, multiple movable baffles 220 are designed in this embodiment to accommodate the laying of wire harnesses 1 of various quantities and specifications.

[0044] This embodiment also provides an energy storage device, including a battery, electrical components, a wiring harness 1, and an energy storage container of any of the above embodiments. The battery is installed in the first chamber 110, the electrical components are installed in the second chamber 120, and the wiring harness 1 passes through a through hole 2101 on the fixed partition 210 to connect the battery and the electrical components. A movable baffle 220 presses the wiring harness 1 against the through hole 2101 and locks it by a locking part 230, thereby reducing the gap around the wiring harness 1 at the through hole 2101 and reducing the impact of the temperature and humidity of the first chamber 110 on the second chamber 120.

[0045] Furthermore, the energy storage device in this embodiment also includes a sealing element (not shown in the figure), which fills the gap between the movable baffle 220 and the fixed partition 210, and also fills the gap between the movable baffle 220 and the wall of the through hole 2101. By providing the sealing element, the first chamber 110 and the second chamber 120 can be effectively isolated, protecting the electrical equipment and other components in the second chamber 120 from damage.

[0046] Optionally, the sealant can be fireproof putty or sealant, which can adapt to gaps of various shapes and sizes and provide a good sealing effect.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them.
