[0055] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0056] In this document, ordinal numbers such as "first" and "second" used in this invention are merely identifiers and do not have any other meaning, such as a specific order. Moreover, for example, the term "first component" does not imply the existence of "second component," and the term "second component" does not imply the existence of "first component."

[0057] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0058] This invention provides an outdoor energy storage cabinet, the interior of which can house batteries and equipment (such as motors). The outdoor energy storage cabinet can be fixedly installed in any location within the city (e.g., outdoors) as needed to provide electrical power or operate via equipment.

[0059] refer to Figure 1 As shown, the outdoor energy storage cabinet includes a cabinet body 20 and an outdoor energy storage cabinet base 10. The cabinet body 20 is positioned above the outdoor energy storage cabinet base 10, and its bottom end is connected to the outdoor energy storage cabinet base 10. Batteries and equipment are placed inside the cabinet body 20, and the corresponding batteries and equipment are placed on the outdoor energy storage cabinet base 10. In this way, the cabinet body 20 and the outdoor energy storage cabinet base 10 provide protection for the internal batteries and equipment, facilitating safe handling and use.

[0060] The handling structure of the outdoor energy storage cabinet can be equipped with a fixing ring (not shown) at the top of the cabinet body 20. The fixing ring can be used by a crane to lift or fix the outdoor energy storage cabinet.

[0061] Regardless of whether the outdoor energy storage cabinet is being hoisted or fixed during installation, the base 10 of the outdoor energy storage cabinet is the first part to contact the ground. If it can buffer the impact of the entire outdoor energy storage cabinet touching the ground, it can reduce the impact on the battery inside the cabinet 20 and prevent the battery from catching fire due to the impact.

[0062] This utility model provides a base 10 for an outdoor energy storage cabinet, which is used to buffer the impact of the outdoor energy storage cabinet on the battery inside the cabinet 20 when it is hit by the ground.

[0063] In some embodiments of this utility model, reference is made to Figures 2 to 6 As shown, the outdoor energy storage cabinet base 10 includes an outer frame. The outer frame includes a first connecting member 11, a second connecting member 12, and an energy-absorbing member 13; wherein, there are two first connecting members 11, which are parallel to each other; there are two second connecting members 12, which are parallel to each other. The second connecting members 12 and the first connecting members 11 are arranged perpendicular to each other. The energy-absorbing member 13 is connected to both the first connecting member 11 and the second connecting member 12. The two first connecting members 11, the two second connecting members 12, and the energy-absorbing member 13 form the outer frame.

[0064] The base 10 of this outdoor energy storage cabinet is made of steel, specifically the first connecting member 11, the second connecting member 12, and the energy-absorbing member 13 are all made of steel. When the outdoor energy storage cabinet experiences a ground impact, it typically occurs at the four corners of the base 10. In the outer frame structure of the base 10, the energy-absorbing member 13 connects to the mutually perpendicular first connecting member 11 and the second connecting member 12, precisely at the four corners of the base 10. The energy-absorbing member 13 absorbs the impact energy of the ground impact, deforms itself, and acts as a buffer.

[0065] The parallelism of the two first connecting members 11 and the two second connecting members 12 mentioned above falls into the category of approximately parallel; at the same time, the second connecting member 12 and the first connecting member 11 are arranged perpendicularly to each other, which also falls into the category of approximately perpendicular.

[0066] The energy-absorbing component 13 of this invention has an internal cavity 139. The energy-absorbing component 13 includes a first connecting wall 132, a second connecting wall 133, and a connecting portion. The connecting portion is located between the first connecting wall 132 and the second connecting wall 133, and is at least partially configured as an opening 131 communicating with the internal cavity 139, with the opening 131 facing the interior of the outer frame. The first connecting wall 132 is connected to the first connecting member 11; the second connecting wall 133 is connected to the second connecting member 12.

[0067] The energy-absorbing component 13 is provided with an internal cavity 139, and combined with an opening 131 communicating with the internal cavity 139, the opening 131 is provided to facilitate the deformation of the wall of the internal cavity 139, so that when the entire energy-absorbing component 13 is subjected to a collision impact, the energy of the collision impact will cause the outer wall of the internal cavity 139 to deform, thereby the impact energy is absorbed by the energy-absorbing component 13. Relatively speaking, the energy-absorbing component 13 plays a buffering role.

[0068] In some embodiments of this utility model, reference is made to Figure 4 As shown, the energy-absorbing component 13 also includes a top wall 136, a bottom wall 138, and a side wall. The top wall 136 and the bottom wall 138 are arranged in parallel, and the side wall is perpendicularly connected to the top wall 136 and the bottom wall 138, forming an internal cavity 139 of the energy-absorbing component 13. The top wall 136 and the bottom wall 138 are respectively connected to the first connecting wall 132 and the second connecting wall 133. The first connecting wall 132 and the second connecting wall 133 are disposed on the side wall, and the side wall constitutes the aforementioned connecting portion.

[0069] The energy-absorbing component 13 is a solid structure formed by a top wall 136, a bottom wall 138, and a side wall. Because the energy-absorbing component 13 has an opening 131 connecting to the inner wall cavity 139, and this opening 131 is not covered, the energy-absorbing component 13 forms an open-top box. The energy-absorbing component 13 is connected to a first connecting component 11 and a second connecting component 12 that are perpendicular to each other. More specifically, the first connecting component 11 is connected to the first connecting wall 132, and the second connecting component 12 is connected to the second connecting wall 133. The energy-absorbing component 13 is located at the corner of the energy storage outdoor cabinet base 10, and the opening 131 faces inwards towards the outer frame, placing it on the side wall between the first connecting wall 132 and the second connecting wall 133. The opening 131 faces inwards towards the outer frame, but is not limited to facing the center of the outer frame.

[0070] A portion of the sidewall is provided with an opening 131, so the sidewall itself forms an open ring. The specific sidewall also includes a first sidewall 123 and a second sidewall 124. The first connecting wall 132, the first sidewall 123, the second sidewall 124 and the second connecting wall 133 are arranged to be connected to each other in sequence, and the two adjacent connected ones are arranged to be bent.

[0071] This utility model uses multiple sections of walls to be bent and connected in sequence to form the side wall of the energy-absorbing component 13. In particular, the first connecting wall 132 and the second connecting wall 133 are set at intervals, so that the entire side wall can be completed by bending and fixing the adjacent walls, which is simple to manufacture.

[0072] More preferably, the first connecting wall 132, the first side wall 123, the second side wall 124 and the second connecting wall 133 are constructed as one piece. During manufacturing, the entire outer wall can be completed by bending the entire wall at a specific position, which makes the operation simpler.

[0073] In some embodiments of this utility model, reference is made to Figure 3 , Figure 4 and Figure 5 As shown, the energy-absorbing component 13 of this invention also has a first energy-absorbing plate 15 inside the internal cavity 139. The first energy-absorbing plate 15 is vertically connected to both the first connecting wall 132 and the second connecting wall 133. The arrangement of the first energy-absorbing plate 15 increases the deformable component of the energy-absorbing component 13, thereby increasing the energy threshold that can be absorbed, without affecting the ability to deform.

[0074] The first energy-absorbing piece 15 is connected to the first connecting wall 132 and the second connecting wall 133, which is a fixed connection including the welding mode.

[0075] In some embodiments of this utility model, reference is made to Figure 3 , Figure 4 and Figure 5 As shown, the first energy-absorbing sheet 15 of this utility model is provided with a first notch 151. The location of the first notch 151 can be on the side away from the opening 131, or at the corner opposite to the opening 131.

[0076] The first notch 151 is set to adjust the deformation performance of the first energy-absorbing piece 15 itself, and the deformation performance of the entire base will also be different depending on the position of the first notch 151.

[0077] The first notch 151 is located on the side of the first energy-absorbing plate 15 away from the opening 131, meaning it is not in contact with the first connecting wall 132 or the second connecting wall 133. (Refer to...) Figures 2 to 6 As shown, the sidewall is composed of a first connecting wall 132, a first sidewall 123, a second sidewall 124, and a second connecting wall 133 connected sequentially. The first notch 151 is located on the side that connects with the first sidewall 123 or the second sidewall 124. The first notch 151 is located at the corner opposite to the opening 131, meaning it is not at the corner between the opening 131 and the first connecting wall 132 or the second connecting wall 133. (Refer to...) Figures 2 to 6 As shown, the first notch 151 at the corner is located between the first side wall 123 and the second side wall 124. It can also be located at the corner between the first connecting wall 132 and the first side wall 123, or between the second side wall 124 and the second connecting wall 133.

[0078] The energy-absorbing component 13 is a cavity structure. The first energy-absorbing piece 15, which is disposed in the inner cavity 139, is vertically connected to the first connecting wall 132 and the second connecting wall 133 and is arranged parallel to the top wall 136 of the energy-absorbing component 13. The present invention provides a second notch 137 in the top wall 136, and the position of the second notch 137 corresponds to the position of the first notch 151 in the first energy-absorbing piece 15, that is, the projections of the two notches in the vertical direction coincide.

[0079] The top wall 136 is provided with a second notch 137, which also changes the deformation capacity of its own structure and the entire base structure, and adjusts the elastic deformation capacity when impacted. At the same time, the second notch 137 of the top wall 136 can also help to position the cabinet 20 when it is assembled onto the energy storage outdoor cabinet base 10.

[0080] The first connecting member 11 and the second connecting member 12 of the outdoor energy storage cabinet base 10 may also be subject to impact during actual lifting. In this invention, both the first connecting member 11 and the second connecting member 12 are designed as through-slot structures, with the slot openings facing the outer periphery of the outer frame. This ensures that when the first connecting member 11 or the second connecting member 12 is impacted, the sidewalls of the through-slot structure are impacted first, deforming to absorb the impact energy and providing a buffering effect.

[0081] refer to Figure 1 As shown, both the first connecting member 11 and the second connecting member 12 adopt a through-slot structure, and the slot end of the through-slot structure is connected to the first connecting wall 132 or the second connecting wall 133, which can be achieved by welding. The through-slot structure of the first connecting member 11 or the second connecting member 12 is directly connected to the first connecting wall 132 or the second connecting wall 133, forming an open box shape, which improves the structural strength and load-bearing capacity of the first connecting member 11 or the second connecting member 12. In contrast, it reduces the need to set end plates at the ends of the through-slot structure of the first connecting member 11 or the second connecting member 12 to form a box shape, saving materials and reducing production costs.

[0082] The through-slot structure can be specifically designed as channel steel, see reference. Figure 1 and Figure 7 As shown, the bottom of the channel steel of the first connecting member 11 is provided with a through hole (not shown), which is used to fix the cabinet 20 above the energy storage outdoor cabinet base 10. This invention provides a second energy-absorbing plate 14 on the side of this through hole. The second energy-absorbing plate 14 is perpendicular to the axial direction of the channel steel and connected to the inner wall of the channel steel. The through hole in the channel steel causes a strength loss at this point. Providing the second energy-absorbing plate 14 on the side of the through hole enhances the strength at this point. Simultaneously, when the first connecting member is subjected to a collision impact, the second energy-absorbing plate 14 deforms, absorbing the impact energy and acting as a buffer.

[0083] In the channel steel structure of the second connecting member 12, the second energy-absorbing piece 14 may not be provided, or the second energy-absorbing piece 14 may be provided in the middle position.

[0084] The number of second energy-absorbing plates 14 set inside the channel steel and the spacing between connected second energy-absorbing plates 14 can be designed based on the weight of the cabinet 20 and its internal equipment supported by the outdoor energy storage cabinet base 10, according to finite element simulation.

[0085] The through-slot structure can also be designed with a near-S-shaped cross-section, see reference. Figure 8 As shown, the cross-sectional shape of the through-slot structure includes a first lateral extension 102, a first longitudinal extension 105, a second lateral extension 103, a second longitudinal extension 106, and a third lateral extension 104. The first lateral extension 102, the second lateral extension 103, and the third lateral extension 104 are arranged in parallel at intervals. The first longitudinal extension 105 and the second longitudinal extension 106 are arranged in parallel with a staggered arrangement. The first longitudinal extension 105 is perpendicular to the first lateral extension 102, and its two ends are respectively connected to the same end of the first lateral extension 102 and the second lateral extension 103. The second longitudinal extension 106 is perpendicular to the second lateral extension 103, and one end of its extension is connected to the other end of the second lateral extension 103, and the other end is connected to the end of the third lateral extension 104 corresponding to the other end of the second lateral extension 103.

[0086] The through-slot structure, with a near-S-shaped cross-section, can form two through slots: the first lateral extension 102, the first longitudinal extension 105, and the second lateral extension 103 constitute the first slot 107; the second lateral extension 103, the second longitudinal extension 106, and the third lateral extension 104 constitute the second slot 108. (Reference) Figure 8 As shown, the opening of the first slot 107 faces the opposite direction to the opening of the second slot 108. For example, the opening of the first slot 107 faces the outer periphery of the outer frame, while the opening of the second slot 108 faces the inside of the outer frame. When the base 10 of the outdoor energy storage cabinet is impacted, the sidewall of this through-slot structure will be impacted first, and multiple deformations will occur to absorb the impact energy, thus playing a buffering role.

[0087] The through-slot structure, with a near-S-shaped cross-section, has through holes for fixing the cabinet 20 above the energy storage outdoor cabinet base 10. At least two second energy-absorbing plates 14 can be installed in the through-slot, one in the first slot 107 and the other in the second slot 108. More specifically, one second energy-absorbing plate 14 is connected to the inner wall of the first slot 107 perpendicular to its axis and located on the side of the through hole in the first longitudinal extension 105, enhancing the strength at the through hole. Consequently, upon impact, the second energy-absorbing plate 14 deforms and absorbs the impact energy, providing a buffering effect. Similarly, another second energy-absorbing plate 14 is connected to the inner wall of the second slot 108 perpendicular to its axis and located on the side of the through hole in the second longitudinal extension 106, enhancing the strength at the through hole. Similarly, upon impact, the second energy-absorbing plate 14 deforms and absorbs the impact energy, providing a buffering effect.

[0088] The aforementioned outdoor energy storage cabinet base 10 has an outer frame formed by two parallel first connecting members 11, two parallel second connecting members 12, and four energy-absorbing members 13, as shown in the reference. Figure 1 As shown, the outdoor energy storage cabinet base 10 can also be equipped with reinforcing ribs, which are installed inside the outer frame to enhance the structural strength of the outer frame. Specifically, at least two reinforcing ribs are provided, and they are arranged perpendicular to each other. The two ends of one reinforcing rib are respectively connected to two first connecting members 11, and the two ends of the other reinforcing rib are respectively connected to two second connecting members 12.

[0089] The structure of the reinforcing rib can be the same as that of the first connecting member 11 or the second connecting member 12, or it can be other similar structures, which will not be described in detail here.

[0090] Furthermore, this utility model also provides an outdoor energy storage cabinet, which includes the aforementioned outdoor energy storage cabinet base 10, a cabinet body 20 mounted on the base 10, and equipment including batteries installed inside the cabinet body 20. During the hoisting process of the outdoor energy storage cabinet, whether it falls during hoisting or lands after being hoisted, the outdoor energy storage base 10 will be the first to hit the ground and be subjected to the impact. However, based on the fact that the outdoor energy storage cabinet base 10 of this utility model can absorb the energy of the impact, some of its components will deform, thereby playing a mitigating role, reducing the impact on the batteries inside the cabinet body 20, and avoiding the risk of battery fire.
