Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of outdoor energy storage equipment, and in particular to a pressure-bearing piece and an outdoor energy storage equipment. BACKGROUND

[0002] The outdoor energy storage complete machine has single-machine or parallel-machine use scenarios in use. When the outdoor energy storage complete machine is used in single-machine mode, the human direct sitting on the top of the machine needs to be considered. When the outdoor energy storage complete machine is used in parallel-machine mode, the stacking use of multiple machines needs to be considered. These use scenarios will cause the top shell of the outdoor energy storage complete machine to bear a large pressure. In the related art, the outdoor energy storage complete machine is usually composed of a top shell, a bottom shell, a support frame and a battery module. The two ends of the support frame are connected with the top shell and the bottom shell, respectively, so that the pressure borne by the top shell is transmitted to the bottom shell through the support frame, and then transmitted to the ground through the bottom shell, so that the top shell can bear a certain pressure.

[0003] However, in order to save costs and improve space utilization, most outdoor energy storage complete machines usually set a large span between two adjacent support frames, so that the top shell cannot effectively transmit the pressure at the middle position to the support frame, and the top shell directly bears most of the pressure. In order to reduce the weight and save costs, most outdoor energy storage complete machines usually adopt a plastic top shell, so that the strength and hardness of the top shell are low. When the top shell bears a large pressure, the appearance of the top shell will be deformed and damaged, or even directly extruded to the internal electronic devices, causing damage to the outdoor energy storage complete machine, and greatly shortening the service life of the outdoor energy storage complete machine.

[0004] In order to improve the pressure-bearing capacity of the top shell, the outdoor energy storage complete machine in the related art is provided with a sheet metal straight beam at the bottom of the top cover. The sheet metal straight beam is installed and fixed between the bottom cover and the support frame to improve the rigidity of the top shell, so as to improve the pressure-bearing capacity of the top shell.

[0005] However, the sheet metal straight beam cannot effectively transmit the pressure at the middle position to the support frame, and when the sheet metal straight beam is under stress, a bending moment will be generated, which is easy to cause damage to the sheet metal straight beam, so that the pressure-bearing capacity of the top shell is low. At the same time, since the top shell is indirectly installed and fixed on the support frame through the sheet metal straight beam, before the top shell is installed, the sheet metal straight beam needs to be installed and fixed on the support frame and a frame structure needs to be built, and finally the top shell is installed and fixed on the sheet metal straight beam. Therefore, the assembly difficulty of the outdoor complete machine is high, and the production efficiency of the outdoor energy storage complete machine is greatly reduced. SUMMARY

[0035] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0036] like Figures 1 to 7 As shown, in one embodiment, a pressure-bearing member 100 is used to install and fix the top cover 200 and two support frames 300 of the outdoor energy storage device 10, respectively. The two support frames 300 are a first support frame 310 and a second support frame 320. The pressure-bearing member 100 has an arched structure and includes a connecting portion 110 and two pressure-bearing portions 120 respectively connected to both ends of the connecting portion 110. The two pressure-bearing portions 120 are a first pressure-bearing portion 121 and a second pressure-bearing portion 122. The first pressure-bearing portion 121 is used to connect to the side of the first support frame 310, and the second pressure-bearing portion 122 is used to connect to the side of the second support frame 320. Each pressure-bearing portion 120 is fixed to the top cover 200, and each pressure-bearing portion 120 is adjacent to the end of the connecting portion 110. Used to connect to the top cover 200, the pressure-bearing component 100 can improve the overall rigidity of the top cover 200, enabling the top cover 200 to have better pressure-bearing capacity. At the same time, the pressure-bearing component 100 can transmit the pressure transmitted from the center of the top cover 200 downwards and outwards to the two support frames 300, so that when the pressure-bearing component 100 is under force, it can decompose the pressure into one downward force and two horizontal forces transmitted to the first support frame 310 and the second support frame 320 respectively. This makes the pressure-bearing component 100 not only have good compressive strength, but also effectively transmit the pressure on the center of the top cover 200 to the two support frames 300, thereby greatly improving the pressure-bearing capacity of the top cover 200 and effectively extending the service life of the outdoor energy storage device 10.

[0037] like Figures 1 to 7As shown, further, the pressure-bearing piece 100 can be installed on the two sides of the support frame 300 and fixed to the top cover 200. Compared with the outdoor energy storage machine in the prior art, the top cover 200 of the present disclosure does not need to be indirectly installed on the two support frames 300 through the pressure-bearing piece 100, so that the outdoor energy storage device 10 of the present disclosure can be assembled without building a frame structure before installing the top cover 200, greatly reducing the assembly difficulty of the outdoor energy storage device 10 of the present disclosure, and thereby greatly improving the production efficiency of the outdoor energy storage device 10 of the present disclosure.

[0038] In this embodiment, the top cover 200 will be subjected to a large pressure during the single-machine or parallel-machine use of the outdoor energy storage device 10. The pressure at both ends of the top cover 200 is directly transmitted to the support frame 300, while the pressure at the center of the top cover 200 is transmitted to the pressure-bearing piece 100. When the pressure-bearing piece 100 is subjected to pressure, the pressure-bearing piece 100 can not only transmit the pressure downward and outward to the two support frames 300, so that the pressure-bearing piece 100 can decompose the pressure into one downward horizontal force and two horizontal forces respectively transmitted to the first support frame 310 and the second support frame 320 when subjected to force, but also effectively transmit the pressure at the center of the top cover 200 to the two support frames 300, thereby greatly improving the pressure-bearing capacity of the top cover 200.

[0039] The pressure-bearing piece 100 described above, since the pressure-bearing piece 100 is an arch-shaped structure, the pressure-bearing piece 100 includes a connecting portion 110 and two pressure-bearing portions 120 respectively connected to both ends of the connecting portion 110. The two pressure-bearing portions 120 are respectively a first pressure-bearing portion 121 and a second pressure-bearing portion 122. The first pressure-bearing portion 121 is used to connect to the side of the first support frame 310, and the second pressure-bearing portion 122 is used to connect to the side of the second support frame 320. Each pressure-bearing portion 120 is used to be fixed to the top cover 200. The end portion of each pressure-bearing portion 120 adjacent to the connecting portion 110 is used to be connected to the top cover 200, so that the pressure-bearing piece 100 can improve the overall stiffness of the top cover 200, so that the top cover 200 can have better pressure-bearing capacity. At the same time, the pressure-bearing piece 100 can transmit the pressure transmitted at the center of the top cover 200 downward and outward to the two support frames 300, so that the pressure-bearing piece 100 can decompose the pressure into one downward horizontal force and two horizontal forces respectively transmitted to the first support frame 310 and the second support frame 320 when subjected to force. Therefore, the pressure-bearing piece 100 not only has good pressure resistance, but also can effectively transmit the pressure at the center of the top cover 200 to the two support frames 300, thereby greatly improving the pressure-bearing capacity of the top cover 200 and effectively prolonging the service life of the outdoor energy storage device 10.

[0040] In addition, since the pressure bearing piece 100 can be installed on the two support frames 300 and fixed to the top cover 200, compared with the outdoor energy storage device in the related art, the top cover 200 of the present disclosure does not need to be indirectly installed on the two support frames 300 through the pressure bearing piece 100, so that the outdoor energy storage device 10 of the present disclosure can be assembled without building a frame structure before installing the top cover 200, which greatly reduces the assembly difficulty of the outdoor energy storage device 10 of the present disclosure, and further greatly improves the production efficiency of the outdoor energy storage device 10 of the present disclosure.

[0041] As shown in Figures 2 to 3 In one embodiment, the first support frame 310 and the second support frame 320 are both installed on the bottom shell 700 of the outdoor energy storage device 10, and the bottom shell 700 is arranged opposite to the top cover 200. The pressure bearing piece 100 is abutted and supported on the top cover 200. The pressure bearing piece 100 is in an arch-shaped structure, that is, the protruding direction of the pressure bearing piece 100 is opposite to the pressure receiving direction X. The pressure bearing piece 100 can transmit the pressure transmitted at the center of the top cover 200 downward and outward to the two support frames 300, so that the pressure bearing piece 100 can decompose the pressure into a downward horizontal force and two horizontal forces respectively transmitted to the first support frame 310 and the second support frame 320 when subjected to force. Therefore, the pressure bearing piece 100 not only has good pressure resistance, but also can effectively transmit the pressure received at the center of the top cover 200 to the two support frames 300, thereby greatly improving the pressure bearing capacity of the top cover 200 and effectively prolonging the service life of the outdoor energy storage device 10. In this embodiment, the pressure bearing piece 100 is in a structure protruding away from the bottom shell 700.

[0042] As shown in Figures 3 to 4 In one embodiment, the first pressure bearing part 121 and the second pressure bearing part 122 are symmetrically arranged relative to the middle position of the connecting part 110, so that the pressure bearing piece 100 can be uniformly stressed, the structural stability of the pressure bearing piece 100 is improved, and the pressure bearing capacity of the top cover 200 is further improved.

[0043] As shown in Figures 3 to 4 In one embodiment, the thickness of each pressure bearing part 120 along the pressure receiving direction X is greater than the thickness of the connecting part 110 along the pressure receiving direction X, so as to reduce the weight of the pressure bearing piece 100, thereby reducing the weight of the outdoor energy storage device 10; at the same time, the use of materials of the pressure bearing piece 100 can be reduced, thereby reducing the production cost of the outdoor energy storage device 10.

[0044] As shown in Figures 3 to 4 In one embodiment, the two pressure bearing parts 120 and the connecting part 110 are integrally formed, so as to improve the structural compactness of the pressure bearing piece 100, and further improve the pressure bearing capacity of the top cover 200.

[0045] As shown in Figures 3 to 6As shown, in one of the embodiments, the top of each pressure bearing part 120 is formed with an arc-shaped abutting surface 123, which is used to abut in the arc-shaped groove 210 of the top cover 200, so as to increase the contact area between the pressure bearing part 100 and the top cover 200, so that the top cover 200 can better transmit the pressure received to the pressure bearing part 100, thereby improving the pressure bearing capacity of the top cover 200.

[0046] As shown, in one of the embodiments, the top of each pressure bearing part 120 is formed with an arc-shaped abutting surface 123, which is used to abut in the arc-shaped groove 210 of the top cover 200, so as to increase the contact area between the pressure bearing part 100 and the top cover 200, so that the top cover 200 can better transmit the pressure received to the pressure bearing part 100, thereby improving the pressure bearing capacity of the top cover 200. Figures 1 to 7 As shown, the present disclosure also provides an outdoor energy storage device 10, which comprises a top cover 200, a first support frame 310, a second support frame 320, and the pressure bearing part 100 described in any of the above embodiments.

The top cover 200 can improve the overall stiffness of the top cover 200, so that the top cover 200 can have better pressure bearing capacity. At the same time, the pressure bearing part 100 can transmit the pressure transmitted at the center of the top cover 200 downward and outward to the two support frames 300, so that the pressure bearing part 100 can decompose the pressure into a downward force and two horizontal forces transmitted to the first support frame 310 and the second support frame 320 respectively when stressed. The pressure bearing part 100 not only has good pressure resistance, but also can effectively transmit the pressure received at the center of the top cover 200 to the two support frames 300, thereby greatly improving the pressure bearing capacity of the top cover 200 and effectively prolonging the service life of the outdoor energy storage device 10. The top end of the first support frame 310 and the top end of the second support frame 320 are fixedly connected to the bottom of the top cover 200, so that the top cover 200 can transmit the pressure received to the support frame 300.
