[0036] The applicant noted that energy storage systems contain many critical control devices, such as local controllers, battery management systems, and battery system controllers, which need to continue operating for a period of time after a power outage. Alternatively, some devices may require startup before the system is powered on. Therefore, a UPS (Uninterruptible Power Supply) is necessary. Currently, UPS systems are typically fixed using sheet metal clamps. However, when space is limited in the energy storage system, maintenance and testing are inconvenient due to proximity to nearby live components such as copper busbars, posing a risk of electric shock.

[0037] In view of this, the fixing structure of this application embodiment is used to fix the electrical device 2 inside the enclosure. In this application embodiment, the electrical device 2 can be a UPS component, and UPS generally requires heating and temperature monitoring. The fixing structure includes a fixing component 1, which includes a clamping member 10 and a fixing member 11 connected to each other. The fixing member 11 is used to connect the clamping member 10 to the enclosure, so that the clamping member 10 and the enclosure form an accommodating space 12 for accommodating the electrical device 2. The clamping member 10 is used to confine the electrical device 2 within the accommodating space 12, and the clamping member 10 is used to support the heating component 20 and the temperature control element 21 of the electrical device 2. This configuration is simple in structure, can improve space utilization, and the fixing component 1 can easily and quickly fix the electrical device 2 and provide a certain degree of vibration buffering. The heating component 20 and temperature control element 21 of the electrical device 2 are mounted on the clamping member 10, which can improve the safety of operation during testing and maintenance; by ensuring that the distance between the heating component 20 and temperature control element 21 and the electrical device 2 is reasonable, the operating temperature of the electrical device 2 can be accurately monitored and adjusted, thereby improving the reliability of the temperature control of the electrical device 2.

[0038] The fixed structure and energy storage system of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.

[0039] Figure 1 is a structural schematic diagram of a fixing structure according to an embodiment of the present application; Figure 2 is a structural schematic diagram of a fixing structure according to another embodiment of the present application; Figure 3 is a structural schematic diagram of a fixing structure according to yet another embodiment of the present application; Figure 4 is a structural schematic diagram of a fixing structure and electrical device 2 according to an embodiment of the present application; Figure 5 is a structural schematic diagram of a fixing structure and electrical device 2 according to yet another embodiment of the present application; Figure 6 is a structural schematic diagram of a fixing structure and electrical device 2 according to yet another embodiment of the present application.

[0040] Referring to Figures 1 to 6, this application embodiment provides a fixing structure for fixing an electrical device 2 inside a housing. In this embodiment, the electrical device 2 can be a UPS assembly, which generally requires heating and temperature monitoring. The fixing structure includes a fixing component 1, which includes a clamping member 10 and a fixing member 11 connected to each other. The fixing member 11 is used to confine the clamping member 10 inside the housing, so that the clamping member 10 and the housing form a receiving space 12 for accommodating the electrical device 2. The clamping member 10 is used to fix the electrical device 2 within the receiving space 12, and the clamping member 10 is used to support the heating component 20 and the temperature control element 21 of the electrical device 2. The UPS assembly may not work properly or may even be damaged in low-temperature environments. Exemplarily, the heating component 20 can be a ceramic heating element, a heating wire, a PTC heater, or other components. The heating component 20 can ensure that the UPS assembly operates stably within a suitable temperature range. For example, the temperature control element 21 can be a thermistor, temperature sensor, temperature control switch, or other components. The temperature control element 21 is used to detect the ambient temperature in real time. When the temperature is lower than the set value, the controller of the electrical device 2 can activate the heating component 20. When the temperature is higher than the set value, the controller of the electrical device 2 can activate the cooling fan or other heat dissipation components on the heating component 20 to dissipate heat from the electrical device 2, thereby ensuring a uniform temperature distribution around the electrical device 2 and avoiding local overheating or overcooling. In addition, the contact area between the clamping member 10 and the electrical device 2 is small, which can avoid affecting the heat dissipation of the electrical device 2 and ensure that the electrical device 2 operates stably within a suitable temperature range.

[0041] This design simplifies the fixing structure, improves space utilization within the enclosure, and allows for quick and easy fixation of the electrical device 2 while providing some vibration damping. The heating element 20 and temperature control element 21 of the electrical device 2 are mounted on the clamping member 10, increasing the distance between them and live components such as copper busbars around the electrical device 2, thus enhancing operational safety during testing and maintenance. By ensuring a reasonable distance between the heating element 20 and temperature control element 21 and the electrical device 2, the operating temperature of the electrical device 2 can be accurately monitored and adjusted, improving the reliability of temperature control.

[0042] In some embodiments, the number of clamping members 10 is multiple, and the multiple clamping members 10 are spaced apart; the fixing component 1 also includes a connector 13, which connects the multiple clamping members 10. The multiple clamping members 10 are flexibly arranged according to the shape and size of the electrical device 2, and connected by the connector 13, thereby further improving the structural stability of the electrical device 2. In the embodiments shown in Figures 1 to 3, two clamping members 10 are spaced apart along a first direction X, and the two clamping members 10 are respectively connected to the housing by fixing members 11. The distance between the two clamping members 10 in the first direction X is adjusted according to the size of the electrical device 2, and they are connected by the connector 13 to increase the connection stability between the clamping members 10.

[0043] In some embodiments, the fastener 11 may be a fastener such as a press-fit screw, and the clamping member 10 is fixed to the housing by the press-fit screw and nut, which can achieve quick installation, is suitable for thin plate structures such as housings, and can provide a reliable connection without damaging the housing.

[0044] In the embodiments shown in Figures 1 to 4, the fixing structure further includes a mounting member 3, which is connected to the clamping member 10 and is used to support the heating assembly 20. The mounting member 3 includes a body 30 and a first supporting part 31 connected to each other, and the body 30 is connected to the clamping member 10. When there are multiple clamping members 10, the body 30 can be connected to multiple clamping members 10 respectively. The first supporting part 31 is used to support the heating assembly 20. The body 30 is provided with a vent hole 300, and the orthographic projection of the vent hole 300 on the electrical device 2 at least partially coincides with the orthographic projection of the heating assembly 20 on the electrical device 2. The vent hole 300 is arranged opposite to the heating assembly 20. In the embodiments of this application, by providing a vent hole 300 on the body 30, on the one hand, it is convenient to confirm the installation position of the heating assembly 20; on the other hand, the heating assembly 20 is arranged opposite to the electrical device 2 through the vent hole 300, so that it can directly blow on the electrical device 2 when the heating assembly 20 is working, thereby improving the heating efficiency of the heating assembly 20 and improving the reliability of the temperature control of the electrical device 2.

[0045] In the embodiments shown in Figures 1 to 3, the first support portion 31 is provided with a first guide rail 310, which is used to mount the heating component 20. The heating component 20 can slide along the first guide rail 310 to adjust its position. By adjusting its position through sliding, the heating component 20 can be quickly positioned to an optimal working position, reducing installation time and debugging difficulty. The heating component 20 can be fixed to the first guide rail 310 by means of clips, screws, pins, etc., facilitating quick disassembly and replacement of the heating component 20. During maintenance or replacement, it is not necessary to disassemble the entire fixing structure; only the heating component 20 needs to be removed individually.

[0046] In the embodiment shown in Figure 1, the mounting component 3 further includes a second support portion 32, which is connected to the body 30. A second guide rail 320 is provided on the second support portion 32 for mounting the temperature control element 21. The first support portion 31 and the second support portion 32 can be spaced apart along a second direction Y. In some embodiments, the second support portion 32 can be located on the side of the first support portion 31 away from the fixing member 11. The second guide rail 320 is located on the second support portion 32 to mount the temperature control element 21. The temperature control element 21 can slide along the second guide rail 320 to adjust its position. By sliding and adjusting its position, the temperature control element 21 can be quickly positioned to a better working position, reducing installation time and debugging difficulty, and ensuring the reliability of temperature control of the electrical device 2. Furthermore, during testing and maintenance, operators can easily operate without reaching into the bottom of the enclosure, effectively reducing the risk of electric shock and improving the efficiency and safety of testing and maintenance. The temperature control element 21 can be fixed to the second guide rail 320 by means of clips, screws, pins, etc., facilitating quick disassembly and replacement of the temperature control element 21. During maintenance or replacement, there is no need to disassemble the entire fixed structure; only the temperature control element 21 needs to be removed separately.

[0047] In the embodiment shown in Figure 2, the fixing structure includes a third guide rail 4, which is connected to the side of the clamping member 10 away from the mounting member 3. The third guide rail 4 is used to install the temperature control element 21. The temperature control element 21 can slide along the third guide rail 4 to adjust its position. By adjusting its position through sliding, the temperature control element 21 can be quickly positioned to the optimal working position, reducing installation time and debugging difficulty, and ensuring the reliability of temperature control of the electrical device 2. When the heating component 20 is close to live parts such as copper busbars inside the enclosure, setting the third guide rail 4 on the side of the clamping member 10 away from the heating component 20 effectively reduces the risk of electric shock and can further improve the safety of testing and maintenance. The temperature control element 21 can be fixed to the second guide rail 320 by means of clips, screws, pins, etc., which facilitates quick disassembly and replacement of the temperature control element 21. During maintenance or replacement, it is not necessary to disassemble the entire fixing structure; only the temperature control element 21 needs to be removed separately.

[0048] In the embodiment shown in Figure 3, multiple temperature control elements 21 can be flexibly arranged according to the shape and size of the electrical device 2, and this application does not limit this.

[0049] In the embodiments shown in Figures 1 to 3, the clamping member 10 includes a first limiting part 100, a second limiting part 101, and a third limiting part 102. The first limiting part 100 and the second limiting part 101 are disposed opposite to each other, and the third limiting part 102 connects the first limiting part 100 and the second limiting part 101. The fixing member 11 is used to connect the first limiting part 100 and the second limiting part 101 to the housing respectively. The first limiting part 100, the second limiting part 101, and the third limiting part 102 form a clamping structure to clamp the electrical device 2, and the first limiting part 100 and the second limiting part 101 are connected to the housing respectively by the fixing member 11 to further improve the structural stability of the fixing component 1.

[0050] For example, when there are multiple clamping members 10, adjacent first limiting portions 100 can be connected by a connector 13 or a mounting member 3; similarly, adjacent second limiting portions 101 can be connected by a connector 13 or a mounting member 3. In the embodiments shown in Figures 1 to 3, when there are two clamping members 10, adjacent first limiting portions 100 are connected by a mounting member 3, and adjacent second limiting portions 101 are connected by a connector 13. The heating assembly 20 and the temperature control element 21 can be flexibly arranged in at least one of the first limiting portions 100 and the second limiting portions 101 according to the shape and size of the electrical device 2.

[0051] In some embodiments, the fixing structure further includes an adhesive layer (not shown), which is disposed on the side of the clamping member 10 near the electrical device 2. The adhesive layer can play a certain role in vibration buffering, preventing the clamping member 10 from rubbing against the electrical device 2 during installation, maintenance, or vibration conditions, thus avoiding wear on the surface of the electrical device 2.

[0052] In the embodiment shown in Figure 4, a cable tie 33 is provided on the side of the mounting component 3 away from the electrical device 2, which facilitates the convergence of the signal line of the temperature control element 21 with the wiring of the whole machine, and prevents the cable from loosening or falling off due to vibration or external force, thereby improving the reliability of the operation of the electrical device 2.

[0053] According to a second aspect of this application, an energy storage system is provided, including a housing, an electrical device 2, a live component (not shown), and the aforementioned fixing structure. The electrical device 2 is located inside the housing. In this embodiment, the electrical device 2 can be a UPS assembly. UPS systems generally require heating and temperature monitoring. The electrical device 2 includes a heating element 20 and a temperature control element 21. The live component is located inside the housing and spaced apart from the electrical device 2. In this embodiment, the live component includes a copper busbar. The fixing structure is used to fix the electrical device 2 inside the housing. The fixing structure includes a fixing component 1, which includes a clamping member 10 and a fixing member 11 connected together. The fixing member 11 is used to confine the clamping member 10 inside the housing, so that the clamping member 10 and the housing form a receiving space 12 for accommodating the electrical device 2. The clamping member 10 is used to fix the electrical device 2 within the receiving space 12 and to support the heating element 20 and temperature control element 21 of the electrical device 2. UPS assemblies may not function properly or may even be damaged in low-temperature environments. For example, the heating component 20 can be a ceramic heating element, heating wire, PTC heater, or other components. The heating component 20 ensures that the UPS component operates stably within a suitable temperature range. For example, the temperature control element 21 can be a thermistor, temperature sensor, temperature control switch, or other components. The temperature control element 21 is used to detect the ambient temperature in real time. When the temperature is lower than the set value, the controller of the electrical device 2 can activate the heating component 20. When the temperature is higher than the set value, the controller of the electrical device 2 can activate the cooling fan or other heat dissipation components on the heating component 20 to dissipate heat from the electrical device 2, thereby ensuring a uniform temperature distribution around the electrical device 2 and avoiding local overheating or overcooling. In addition, the contact area between the clamping member 10 and the electrical device 2 is small, which can avoid affecting the heat dissipation of the electrical device 2 and ensure that the electrical device 2 operates stably within a suitable temperature range. With this configuration, the fixing structure is simple, which can improve the space utilization within the cabinet. The fixing component 1 can easily and quickly fix the electrical device 2 and provide a certain degree of vibration buffering. The heating element 20 and temperature control element 21 of the electrical device 2 are mounted on the clamping member 10, and the increased distance between them and the copper busbars around the electrical device 2 can improve operational safety during testing and maintenance. By ensuring that the distance between the heating element 20 and temperature control element 21 and the electrical device 2 is reasonable, the operating temperature of the electrical device 2 can be accurately monitored and adjusted, thereby improving the reliability of the temperature control of the electrical device 2.
