[0034] In order to make the purpose, technical scheme and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. However, the example implementation can be implemented in various forms and should not be construed as being limited to the implementations set forth herein. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted. The words expressing position and direction described in the embodiments of the present application are all described with reference to the accompanying drawings as examples, but changes may be made as needed, and the changes made are all included in the scope of protection of the present application. The drawings of the embodiments of the present application are only used to illustrate the relative position relationship and do not represent the true proportion.
[0035] The following description sets forth specific details to facilitate understanding of the present application, but the embodiments of the present application can be implemented in a variety of other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the embodiments of the present application. Therefore, the present application is not limited to the specific implementation methods disclosed below.
[0036] For ease of understanding, the application scenarios of the energy storage cabinet involved in this application are first described. The energy storage cabinet provided in the embodiment of this application can be adapted to the energy field, can be used to accommodate battery packs, and can also be used to accommodate electronic equipment such as power conversion equipment.
[0037] In the related art, the cabinet design is that the cabinet body and the base are connected by screws, or directly welded into one, which has weak shock absorption ability and affects the cabinet body strength and the stability of the equipment in the cabinet. Based on this, the embodiment of the present application provides an energy storage cabinet to reduce the impact of vibration on the cabinet body strength and the equipment in the cabinet.
[0038] First refer to Figure 1 , Figure 1 The schematic diagram of the structure of the energy storage cabinet provided by the present application is shown. In the coordinate directions of the following figures, the direction shown on the x-axis represents the first direction, and the direction shown on the y-axis represents the second direction, and the second direction may be perpendicular to the first direction. Figure 1 As shown, the energy storage cabinet provided in the embodiment of the present application may include a cabinet 100, a shock absorbing part 200 and a base 300. One or more battery packs can be accommodated inside the cabinet 100. There is a gap between the cabinet 100 and the base 300 along the first direction, and the first direction can be understood as the height direction of the cabinet 100, so that the second direction can be understood as the length or width direction of the cabinet 100. In the first direction, the shock absorbing part 200 is arranged between the cabinet 100 and the base 300, and the shock absorbing part 200 is fixedly connected to the cabinet 100 and the base 300, respectively. In actual setting, the number of shock absorbing parts 200 can be multiple, and the multiple shock absorbing parts 200 can be symmetrically distributed in the length and / or width direction of the cabinet 100 to stably support the cabinet 100. Figure 2 A partial structural schematic diagram of the energy storage cabinet provided in this application is shown, such as Figure 2 As shown, the shock absorbing part 200 may be specifically connected to the bottom frame 101 of the cabinet 100 .
[0039] Figure 3 A possible structural schematic diagram of the shock absorbing part of the energy storage cabinet provided in the present application is shown. Figure 1 and Figure 3 As shown, the shock absorbing part 200 is connected to the cabinet 100 through at least one first connecting member 400 , and the shock absorbing part 200 is connected to the base 300 through at least two second connecting members 500 . Figure 3The example shows that the shock absorbing part 200 is connected to the cabinet 100 through a first connector 400 and connected to the base 300 through two second connectors 500. The projection of the first connector 400 in the first direction is misaligned with the projection of the second connector 500 in the first direction, or the first connector 400 and the second connector 500 are misaligned in the second direction. For example, when the shock absorbing part 200 is connected to the cabinet 100 through a first connector 400 and connected to the base 300 through two second connectors 500, the projection of the first connector 400 in the first direction is located between the projections of the two second connectors 500, and the connection point of the shock absorbing part 200 and the cabinet 100 in the first direction falls between the connection points of the shock absorbing part 200 and the base 300, and one connection point of the shock absorbing part 200 and the cabinet 100 and two connection points of the shock absorbing part 200 and the base 300 in the first direction form a similar triangular support. Compared with the overlap of the projection of the first connecting member 400 in the first direction and the projection of the second connecting member 500 in the first direction, the support of the cabinet body 100 by the shock absorbing part 200 is more stable, and the shock absorbing part 200 can be extended and retracted along the first direction, and can also be extended and retracted along a direction with a certain angle to the first direction, so that the shock absorbing part 200 can not only absorb the vibration of the cabinet body 100 in the first direction, but also absorb the vibration of the cabinet body 100 in the second direction. It can be understood that the shock absorbing part 200 can not only absorb the up and down vibration of the cabinet body 100, but also absorb the left and right or front and back shaking of the cabinet body 100.
[0040] In the energy storage cabinet provided in the embodiment of the present application, in normal working scenarios and transportation scenarios, the shock absorbing part 200 can attenuate the vibration transmitted by the base 300, and can also absorb the working vibration of the equipment inside the cabinet 100, thereby reducing the impact of the vibration on the structural strength of the cabinet 100, and at the same time reducing the impact of the vibration on the fixing strength, structural strength and working stability of the equipment inside the cabinet 100, thereby improving the stability of the energy storage cabinet on the basis of low cost and lightweight.
[0041] In a specific implementation, the shock absorbing part 200 may include a first connecting plate 201, a shock absorbing member 202, and a second connecting plate 203, wherein the first connecting plate 201 and the second connecting plate 203 are respectively connected to both sides of the shock absorbing member 202 in the first direction. In the first direction, the projection area of the first connecting plate 201 is larger than the projection area of the shock absorbing member 202, and the projection area of the second connecting plate 203 is also larger than the projection area of the shock absorbing member 202. The shock absorbing member 202 may be connected to the cabinet 100 through the first connecting member 400. The first connecting plate 201 may be connected to the shock absorbing member 202 through the first connecting member 400, and the first connecting plate 201 may be fixedly connected to the cabinet 100. The arrangement of the first connecting plate 201 makes the contact area between the shock absorbing part 200 and the cabinet 100 larger as a whole, and makes the connection between the shock absorbing part 200 and the cabinet 100 more reliable, and the shock absorbing part 200 may effectively absorb the vibration from the cabinet 100. The second connecting plate 203 can be fixedly connected to the base 300 through the second connecting member 500, so as to realize the connection between the second connecting plate 203 and the base 300, thereby realizing the connection between the shock absorbing member 202 and the base 300. The arrangement of the second connecting plate 203 makes the contact area between the shock absorbing member 200 and the base 300 larger, and makes the connection between the shock absorbing member 200 and the base 300 more reliable, so that the shock absorbing member 200 can effectively absorb the vibration from the base 300. Specifically, the first connecting plate 201 is connected to the side of the cabinet 100 facing the base 300 through the first connecting member 400, and the second connecting plate 203 is connected to the side of the base 300 facing the cabinet 100 through the second connecting member 500.
[0042] During specific implementation, the vibration of the cabinet 100 is transmitted to the shock absorbing part 200 through the first connecting plate 201, and the vibration of the base 300 is transmitted to the shock absorbing part 200 through the second connecting plate 203. The shock absorbing part 200 is extended and retracted to absorb the vibration. The projections of the first connecting plate 201 and the second connecting plate 203 in the first direction at least partially overlap. The extension direction of the shock absorbing part 200 can be parallel to or nearly parallel to the first direction. The shock absorbing part 200 supports the cabinet 100 more reliably. At the same time, the shock absorbing part 200 can absorb the vibration in the first direction and the vibration in the second direction. Exemplarily, the first connecting plate 201 is a rectangular plate-shaped structure, and the second connecting plate 203 is also a rectangular plate-shaped structure. The area of the first connecting plate 201 is larger than the area of the second connecting plate 203. The projection of the first connecting plate 201 in the first direction covers the entire second connecting plate 203 or covers a part of the second connecting plate 203.
[0043] The following is a detailed description of possible implementations of the shock absorbing element.
[0044] As a possible implementation, Figure 3As shown, the shock absorbing member 202 can be a shock absorbing pad, and the expansion and contraction direction of the shock absorbing pad is parallel to the first direction. The shock absorbing pad can be made of rubber material, and the shape of the shock absorbing pad can be similar to a cylinder. The shock absorbing pad has a certain elastic deformation amount, and the deformation is relatively flexible, so that the shock absorbing part 200 can absorb the vibration of the cabinet 100 in the first direction, and can also absorb the vibration of the cabinet 100 in the second direction. In the initial state, that is, when no vibration is generated, because the shock absorbing pad supports the cabinet 100, the shock absorbing pad is in a compressed state, and the shock absorbing pad has room for further deformation.
[0045] In a specific implementation, at least two second connecting members 500 are located on both sides of the shock absorbing member 202 in the second direction to enhance the stability of the connection between the second connecting plate 203 and the base 300. Figure 4 As shown, when there are two second connectors 500, the two second connectors 500 are arranged in the second direction, and there is a gap between adjacent second connectors 500. Specifically, the two second connectors 500 can be arranged in the length direction of the cabinet, and there is a gap between adjacent second connectors 500.
[0046] When there is one first connecting member 400, the first connecting member 400 may be located in the middle of the shock absorbing member 202 in the second direction. Figure 4 As shown, when there is one first connector 400 and two second connectors 500, in the second direction, one first connector 400 is located between two second connectors 500. Specifically, one first connector 400 and two second connectors 500 may be located on the same straight line.
[0047] When there are multiple first connectors 400, the multiple first connectors 400 can be concentrated in the middle area of the shock absorber 202 in the second direction, and the multiple first connectors 400 are arranged in the second direction, and there are intervals between adjacent first connectors 400. The first connecting plate 201 is connected to the cabinet 100 through the multiple first connectors 400, and the connection between the first connecting plate 201 and the cabinet 100 is relatively reliable. Exemplarily, when there are two first connectors 400, the two first connectors 400 are arranged in the second direction, and there are intervals between adjacent first connectors 400. Specifically, Figure 5 As shown, the two first connectors 400 can be arranged in the length direction of the cabinet, there is a gap between adjacent first connectors 400, and the straight line formed by connecting the two first connectors 400 can be parallel to or overlap with the straight line formed by connecting the two second connectors 500; Figure 6 As shown, the two first connectors 400 can be arranged in the width direction of the cabinet, there is a gap between adjacent first connectors 400, and the straight line formed by connecting the two first connectors 400 can be perpendicular to the straight line formed by connecting the two second connectors 500. Figure 7As shown, when there are three first connecting members 400, the three first connecting members 400 can be arranged in the width direction of the cabinet, there are gaps between adjacent first connecting members 400, and the straight line formed by connecting the three first connecting members 400 can be perpendicular to the straight line formed by connecting the two second connecting members 500.
[0048] Above Figures 4 to 7 The example shows the case where there are two second connecting members 500. Figure 8 The example shows a case where there are four second connectors 500. The number of the first connector 400 and the second connector 500 can be various. The above embodiments of the present application are only examples and are not intended to be limiting. In actual applications, the number of the first connector 400 and the second connector 500 can be other.
[0049] During the specific connection, one of the first connectors 400 passes through the shock absorber 202, and the first connector 400 has a first end and a second end in the first direction. The first end of the first connector 400 passes through the first connecting plate 201 and extends into the cabinet 100. The first connector 400 connects the cabinet 100, the first connecting plate 201, the shock absorber 202, the second connecting plate 203 and the base 300 as a whole, and the overall structural stability of the energy storage cabinet is relatively high. The first connector 400 can be a screw or a bolt. The end of the first connector 400 with a nut can be regarded as the first end. The second end of the first connector 400 is connected with a nut. By adjusting the installation position of the nut, the maximum distance between the cabinet 100 and the base 300 can be limited. The second end of the first connector 400 passes through the second connecting plate 203 and extends into the base 300. The second connector 500 can be a screw or a bolt.
[0050] In the second direction, the size of the first connecting plate 201 is larger than the size of the shock absorber 202, and the shock absorber 202 is arranged corresponding to the middle part of the first connecting plate 201. The force of the shock absorber 202 is relatively balanced, the deformation is relatively uniform, and the shock absorption is relatively stable. The first connecting plate 201 is fixedly connected to the cabinet 100 through at least two third connecting members 204, and at least two third connecting members 204 are respectively located on both sides of the shock absorber 202 in the second direction. The first connecting plate 201 is connected to the cabinet 100 stably, and the force of the first connecting plate 201 is relatively uniform. There can be multiple third connecting members 204 located on each side of the shock absorber 202 in the second direction, and the number of third connecting members 204 located on both sides of the shock absorber 202 in the second direction can be the same and can be symmetrically distributed. In addition, the first connecting plate 201 is fixedly connected to the cabinet 100 through the third connecting member 204, which can improve the connection strength between the shock absorber 200 as a whole and the cabinet 100.
[0051] Combination Figure 3 and Figure 8As shown, in the second direction, the size of the second connecting plate 203 is larger than the size of the shock absorbing member 202, the second connecting plate 203 has at least two protrusions 2033, the at least two protrusions 2033 are located on both sides of the shock absorbing member 202 in the second direction, and at least two second connecting members 500 respectively penetrate the at least two protrusions 2033 and extend into the base 300. The provision of the protrusions 2033 can increase the contact area between the second connecting plate 203 and the base 300, and the connection between the second connecting plate 203 and the base 300 is relatively reliable, ensuring that the shock absorbing member 202 can absorb the vibration from the base 300 more effectively.
[0052] Fig. 9 Another possible structural schematic diagram of the shock absorbing part of the energy storage cabinet provided in the present application is shown. Fig. 9 As shown, as another possible implementation, the shock absorber 202 can be a spring, which has a strong ability to filter vibrations and a more significant shock absorption effect. The axial direction of the spring is parallel to the second direction, which can be understood as the spring being placed horizontally, so that the spring occupies less space and has a smaller elastic deformation. While playing a shock absorption role, it can prevent the cabinet 100 from shaking to a large extent. In the initial state, that is, when no vibration is generated, since the spring supports the cabinet 100, the spring is in a compressed state and the spring has room for further deformation. When there are multiple first connectors, multiple first connectors are arranged in the axial direction of the spring, and there are intervals between adjacent first connectors. Multiple first connectors are dispersedly connected to the cabinet in the axial direction of the spring to avoid stress concentration. The cabinet 100 is not easy to deform, and the provision of multiple first connectors can also enhance the reliability of the connection between the spring and the cabinet 100. Similarly, multiple second connecting members are arranged in the axial direction of the spring, and there are gaps between adjacent second connecting members. Multiple second connecting members are dispersedly connected to the base 300 in the axial direction of the spring to avoid stress concentration. The base 300 is not easily deformed, and the provision of multiple second connecting members can also enhance the reliability of the connection between the spring and the base 300.
[0053] In a specific implementation, the first connecting plate may include a first connecting block 2011 and a second connecting block 2012, the first connecting block 2011 having a plurality of first grooves arranged along the second direction, the second connecting block 2012 having a plurality of second grooves arranged along the second direction, the plurality of first grooves and the plurality of second grooves corresponding to each other in the first direction.
