Description

Technical Field

[0001] The present application relates to the technical field of new energy storage devices, and in particular to a power module installation structure and an energy storage device. Background Art

[0002] With the development of new energy technology, a method of using DC energy storage devices for high-voltage direct-mounted energy storage has emerged. However, since the energy storage device not only has a power module but also a battery cabinet, the installation space of the energy storage device is relatively cramped, and the installation and fixation of the power module is relatively difficult. Summary of the invention

[0003] In view of the above problems, the present application provides a power module installation structure and an energy storage device, which can make the installation and fixation of the power module of the energy storage device more convenient and time-saving.

[0004] In a first aspect, the present application provides a power module mounting structure, which includes a first mounting plate and a second mounting plate. The first mounting plate is provided with a snap-in slot; the second mounting plate is connected to the first mounting plate and arranged at an angle, and the second mounting plate is provided with a notch arranged opposite to the snap-in slot, and the notch is connected to the snap-in slot.

[0005] When the energy storage device is installed through the above-mentioned power module installation structure, since the first installation plate and the second installation plate are arranged at an angle, and a snap-in groove is constructed on the first installation plate, and a notch connected to the snap-in groove is constructed on the second installation plate, the snap-in groove and the notch can snap-in the installation profile on the power module. Therefore, compared with the structure in which the first installation plate and the second installation plate are arranged in parallel along the width direction of the second installation plate, the power module installation structure provided by the present application occupies a smaller size along the width direction of the second installation plate, and the structure is more compact, so the power module installation structure can be more easily inserted into the narrow installation space between the battery cabinet and the power module, so that it is more convenient and time-saving to install and fix the power module of the energy storage device with a relatively cramped installation space; and it can also make it possible to reserve a smaller installation space between the battery cabinet and the power module when designing the energy storage device, so that the structure of the entire energy storage device is more compact, and the space utilization rate of the energy storage device is increased.

[0006] In some embodiments, the power module mounting structure is further provided with a plurality of positioning members, which are arranged on the second mounting plate and spaced apart along a first direction, wherein the first direction is the length direction of the second mounting plate. By arranging the plurality of positioning members at intervals, and the plurality of positioning members being able to respectively cooperate with one of the positioning holes on the mounting profile, the power module mounting structure is not easy to rotate when the mounting profile is connected to the power module mounting structure, and the position of the power module mounting structure during the installation process is maintained with high precision, the installation precision is high and it is more convenient, and the situation of loose installation can also be effectively reduced. By arranging the plurality of positioning members on the second mounting plate, that is, arranging them on the second mounting plate with a notch. When the power module mounting structure is rotated to clamp the mounting profile, the plurality of positioning members arranged on the second mounting plate can cooperate with the positioning holes on the larger first clamping portion arranged on the mounting profile.

[0007] In some embodiments, the plurality of positioning members include a first positioning member, which is disposed at the notch; an extension portion is protruded outwardly along its own length direction on one side of the second mounting plate away from the notch; and the plurality of positioning members also include a second positioning member, which is disposed at the extension portion. By using the first positioning member to cooperate with one mounting profile and the second positioning member to cooperate with another mounting profile, each power module mounting structure is connected to two mounting profiles, so that a frame-like structure is formed between the power module mounting structure and the two mounting profiles, and the two are not easily deformed after being assembled.

[0008] In some embodiments, the power module mounting structure further includes a third mounting plate, which is connected to a side of the first mounting plate that is away from the second mounting plate, and the extension direction of the third mounting plate is opposite to the extension direction of the second mounting plate. By electrically connecting the third mounting plate to the power module, and since the power module is grounded, the power module mounting structure and the power module can both be grounded, making the use of the energy storage device safer.

[0009] In some embodiments, a grounding nut is constructed on the third mounting plate. The grounding nut is fixedly connected to the power module, and the grounding nut is configured to be connected to the grounding wire. The power module mounting structure is connected to the earth through the grounding nut, so that the power module mounting structure is not easily charged, making the use of the energy storage device safer. At the same time, since the grounding nut is in surface contact with the grounding wire, the grounding effect of the power module mounting structure is better, and the equipotential effect with the power module is also better.

[0010] In some embodiments, the third mounting plate is parallel to the second mounting plate. By setting the third mounting plate to be parallel to the second mounting plate, the grounding nut set on the third mounting plate can be better grounded. At the same time, the gravity distribution of the entire power module mounting structure is more reasonable, which is convenient for holding and installation, thereby reducing the difficulty of installation.

[0011] In some embodiments, the angle θ between the first mounting plate and the second mounting plate satisfies the condition: 90°≤θ<180°. By setting the angle θ between the first mounting plate and the second mounting plate to be greater than or equal to 90° and less than 180°, when the mounting profile is installed with the power module mounting structure, the installation space enclosed by the first mounting plate and the second mounting plate is a right-angle or obtuse-angle installation space, thereby making the installation space larger, facilitating the adjustment and alignment of the mounting profile and the mounting bracket of the energy storage device in the installation space, and making the installation process more convenient.

[0012] In the second aspect, the present application provides an energy storage device, which includes a power module mounting structure of any one of the above-mentioned embodiments, and also includes a mounting profile and a power module; the mounting profile is installed on the power module, and the snap-in groove and the notch are used to snap-in the mounting profile. Since the first mounting plate and the second mounting plate of the energy storage device provided by the present application are arranged at an angle, and the first mounting plate is configured with a snap-in groove, and the second mounting plate is configured with a notch connected to the snap-in groove, the snap-in groove and the notch can snap-in the mounting profile on the power module. Therefore, during the installation process, the user can manually rotate the power module mounting structure so that the accommodating space formed by the notch and the snap-in groove can more easily snap-in the mounting profile, thereby making it more convenient and time-saving to install and fix the power module of the energy storage device with a relatively cramped installation space. Furthermore, since the first mounting plate and the second mounting plate are arranged at an angle, compared with a structure in which the first mounting plate and the second mounting plate are arranged in parallel along the width direction of the second mounting plate, the power module mounting structure provided in the present application occupies a smaller dimension along the width direction of the second mounting plate, and the entire power module mounting structure is relatively compact, so that the power module mounting structure can be more easily inserted into the narrow installation space between the battery cabinet and the power module, thereby making it more convenient and time-saving to install and fix the power module of the energy storage device with a relatively cramped installation space; and it can also enable a smaller installation space to be reserved between the battery cabinet and the power module when designing the energy storage device, so that the structure of the entire energy storage device is relatively compact, thereby increasing the space utilization rate of the energy storage device.

[0013] In some of the embodiments, the energy storage device further includes a mounting bracket, which is mounted on the power module, and the mounting profile and the power module mounting structure are both connected to the mounting bracket. The mounting bracket surrounds the outer circumference of the power module, and the mounting bracket is made of a thinner material. By using the mounting bracket as an intermediate piece, it is convenient to process mounting holes on the mounting bracket that are connected to the mounting profile, without the need to directly process mounting holes on the power module that are connected to the mounting profile, and the processing process is relatively simple. The power module mounting structure, the mounting profile, and the mounting bracket are fixedly connected through the intermediate piece, so that the mounting profile can finally support the power module.

[0014] In one embodiment, the energy storage device further includes a connecting piece, a positioning hole is configured on the mounting profile, a mounting hole is configured on the mounting bracket, and the positioning piece passes through the positioning hole and the mounting hole and is connected to the connecting piece. By passing the positioning piece through the positioning hole and the mounting hole in sequence and connecting with the connecting piece, the fixed connection among the power module mounting structure, the mounting profile and the mounting bracket is finally achieved, and the installation process is relatively simple and convenient.

[0037] With the development of new energy technology, a method of using DC energy storage valves for high-voltage direct hanging energy storage has emerged. Compared with the traditional energy storage method with step-up transformers, high-voltage direct hanging energy storage has the advantages of high safety, high efficiency, strong compatibility, and high cost performance. It can play a role in peak load regulation and frequency regulation in power system transmission and distribution, provide backup power for the power grid, improve the recovery capacity after power grid failure, and ensure the power supply reliability of important loads; in new energy scenarios, it plays a role in energy shifting and smoothing fluctuations, so the application prospects of high-voltage direct hanging energy storage are very broad.

[0038] However, the energy storage device composed of the DC energy storage valve includes power modules, junction boxes and battery cabinets. The connection method is that the submodules are connected in series and the battery cabinets are connected in parallel. This makes the distance between the power module and the battery cabinet of the energy storage device small, the installation space of the power module is relatively cramped, and the installation and fixation are relatively difficult. Increasing the distance will lead to space waste, resulting in low space utilization of the entire energy storage device.

[0039] Based on the above considerations, in order to solve the problem that the installation space of the energy storage device is relatively cramped and the installation and fixation of the power module is relatively difficult, the inventor has designed a power module installation structure after in-depth research. By providing notches and card-connecting grooves that are arranged at an angle and are interconnected on the power module installation structure, and rotating the power module installation structure during the installation process, so that the accommodating space formed by the notch and the card-connecting groove can more easily be carded with the installation profile, thereby making the installation and fixation process of the power module of the energy storage device with a relatively cramped installation space more convenient and time-saving.

[0040] The power module installation structure and energy storage device disclosed in the embodiment of the present application can be used in, but not limited to, electrical devices such as vehicles, ships or aircraft. A power supply system comprising the power module installation structure and energy storage device disclosed in the present application can be used to form the electrical device, so that the installation and fixation of the power module is convenient.

[0041] The embodiment of the present application provides an electric device using a power module mounting structure and an energy storage device as an energy storage power source, and the electric device may be, but is not limited to, a mobile phone, a tablet, a laptop, an electric toy, an electric tool, a battery car, an electric car, a ship, a spacecraft, etc. Among them, the electric toy may include a fixed or mobile electric toy, for example, a game console, an electric car toy, an electric ship toy, an electric airplane toy, etc., and the spacecraft may include an airplane, a rocket, a space shuttle, a spacecraft, etc.

[0042] For the convenience of description, the following embodiments are described by taking a DC energy storage device as an example in some embodiments of the present application.

[0043] According to some embodiments of the present application, referring to Figures 1 to 5, Figure 1 shows a schematic diagram of an energy storage device of some embodiments of the present application. Figure 2 shows a schematic diagram of a power module mounting structure 1000, a mounting profile 2000, a power module 3000, and a mounting bracket 4000 in the energy storage device shown in Figure 1. Figure 3 shows a partial enlarged view of the assembly of the power module mounting structure 1000, the mounting profile 2000, the power module 3000, and the mounting bracket 4000 in the energy storage device shown in Figure 2. Figure 4 shows a first schematic diagram of the power module mounting structure 1000 in the energy storage device shown in Figure 1. Figure 5 shows a second schematic diagram of the power module mounting structure 1000 in the energy storage device shown in Figure 4.

[0044] Referring to FIG. 4 and FIG. 5 , some embodiments of the present application provide a power module mounting structure 1000, which includes a first mounting plate 100 and a second mounting plate 200. The first mounting plate 100 is provided with a clamping groove 110; the second mounting plate 200 is connected to the first mounting plate 100 and arranged at an angle, and the second mounting plate 200 is provided with a notch 210 arranged opposite to the clamping groove 110, and the notch 210 is connected to the clamping groove 110. The clamping groove 110 and the notch 210 are used to clamp the mounting profile 2000 mounted on the power module 3000.

[0045] It should be noted that the power module 3000 is a structure in which power electronic devices are combined according to certain functions and then potted into a module. The mounting profile 2000 is used to support the power module 3000, and the mounting profile 2000 can be a structure such as an I-beam. The power module mounting structure 1000 mounts the mounting profile 2000 and the power module 3000, so that the mounting profile 2000 can support the power module 3000.

[0046] It should be noted that there may be a plurality of mounting profiles 2000, and the plurality of mounting profiles 2000 are arranged at intervals along the length direction of the second mounting plate 200. Specifically, the length direction of the second mounting plate 200 is the xx' direction in FIG. 4. In some embodiments, the mounting profile 2000 includes a first profile 2100, a second profile 2200 and a third profile 2300, and the three third profiles 2300 are all I-beam structures. Taking the first profile 2100 as an example, the first profile 2100 includes a first clamping portion 2110 and a second clamping portion 2120 connected to each other, and the size of the first clamping portion 2110 along the length direction of the second mounting plate 200 is greater than the size of the second clamping portion 2120 along the length direction of the second mounting plate 200, so that the entire first profile 2100 is an I-beam structure. The first clamping portion 2110 is accommodated in the clamping groove 110 , and the second clamping portion 2120 is accommodated in the notch 210 , thereby achieving clamping of the power module mounting structure 1000 and the first profile 2100 .

[0047] The mounting profile 2000 may be made of insulating material, such as plastic, so that electrical conduction is less likely to occur between the power module 3000 and the mounting profile 2000, which is safer.

[0048] The first mounting plate 100 and the second mounting plate 200 can be made of a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, etc., so that the first mounting plate 100 and the second mounting plate 200 are strong and firm, and are also easy to process. The embodiments of the present application do not impose any special restrictions on this.

[0049] The first mounting plate 100 and the second mounting plate 200 may be connected by welding, or may be integrally formed by stamping or the like.

[0050] When the energy storage device is installed through the power module mounting structure 1000 provided in the embodiment of the present application, since the first mounting plate 100 and the second mounting plate 200 are arranged at an angle, and the first mounting plate 100 is configured with a snap-in groove 110, and the second mounting plate 200 is configured with a notch 210 connected to the snap-in groove 110, the snap-in groove 110 and the notch 210 can snap-in the mounting profile 2000 on the power module 3000. Therefore, compared with the structure in which the first mounting plate 100 and the second mounting plate 200 are arranged in parallel along the width direction of the second mounting plate 200, the power module mounting structure 1000 provided in the present application occupies a smaller dimension along the width direction of the second mounting plate 200, that is, along the yy' direction in Figure 1, and the entire power module mounting structure 1000 is relatively compact, so that the power module mounting structure 1000 can be more easily inserted into the narrow installation space between the battery cabinet 5000 and the power module 3000 shown in Figure 1, thereby making it more convenient and time-saving to install and fix the power module 3000 of the energy storage device with a relatively cramped installation space; and it can also make it possible to reserve a smaller installation space between the battery cabinet 5000 and the power module 3000 along the yy' direction in Figure 1 when designing the energy storage device, so that the structure of the entire energy storage device is relatively compact, thereby increasing the space utilization rate of the energy storage device.

[0051] During the installation process, the power module installation structure 1000 can be rotated so that the accommodation space formed by the notch 210 and the clamping groove 110 can more easily clamp the installation profile 2000, thereby making it more convenient and time-saving to install and fix the power module 3000 of the energy storage device with a relatively cramped installation space. In addition, since the first mounting plate 100 and the second mounting plate 200 are arranged at an angle, the entire power module installation structure 1000 can also be made more compact, thereby making the structure of the entire energy storage device more compact, thereby increasing the space utilization rate of the energy storage device.

[0052] The following is a detailed description of the power module mounting structure 1000. Referring to FIG. 2 and FIG. 4, the power module mounting structure 1000 provided in some embodiments of the present application is further provided with a plurality of positioning members 300, which are arranged on the second mounting plate 200 and spaced apart along a first direction, the first direction being the length direction of the second mounting plate 200, and specifically, the first direction being the xx' direction in FIG. 4. The plurality of positioning members 300 are spaced apart, and the plurality of positioning members 300 are respectively used to cooperate with the positioning holes on the mounting profile 2000.

[0053] The positioning member 300 may be a positioning pin, a positioning screw, etc. The positioning member 300 may be fixedly connected to the second mounting plate 200 or the first mounting plate 100 .

[0054] The number of the positioning members 300 may be three or more, and the positions of the positioning members 300 on the second mounting plate 200 match the positions of the positioning holes on the mounting profile 2000. Optionally, the number of the positioning members 300 on each power module mounting structure 1000 is three.

[0055] It should be noted that the power module 3000 is connected to a mounting bracket 4000, and the mounting bracket 4000 is configured with a mounting hole. After the positioning member 300 passes through the positioning hole on the mounting profile 2000 and the mounting hole on the mounting bracket 4000, it is connected to a positioning member, thereby realizing the fixed connection between the power module mounting structure 1000, the mounting profile 2000 and the mounting bracket 4000, and finally enabling the mounting profile 2000 to support the power module 3000. Specifically, the positioning member can be a nut.

[0056] By setting a plurality of positioning members 300 at intervals, and each of the positioning members 300 can cooperate with one of the positioning holes on the mounting profile 2000, the power module mounting structure 1000 is not easy to rotate when the mounting profile 2000 is connected to the power module mounting structure 1000. The position of the power module mounting structure 1000 during the installation process is maintained with high accuracy, the installation accuracy is high and it is more convenient, and the situation of loose installation can be effectively reduced.

[0057] By disposing a plurality of positioning members 300 on the second mounting plate 200, that is, on the second mounting plate 200 having the notch 210, when the power module mounting structure 1000 is rotated to clamp the mounting profile 2000, the plurality of positioning members 300 disposed on the second mounting plate 200 can be matched with the positioning holes disposed on the larger first clamping portion 2110 on the mounting profile 2000.

[0058] Referring to FIG. 2 , the multiple positioning members 300 of the power module mounting structure 1000 provided in some embodiments of the present application include a first positioning member 310, which is disposed at the notch 210, and an extension portion is protruded outwardly along its own length direction on a side of the second mounting plate 200 away from the notch 210; the multiple positioning members 300 also include a second positioning member 320, which is disposed at the extension portion. The first positioning member 310 is used to cooperate with one mounting profile 2000, and the second positioning member 320 is used to cooperate with another mounting profile 2000.

[0059] In one embodiment, the number of positioning members 300 on each power module mounting structure 1000 is three, including two first positioning members 310 and one second positioning member 320. The two first positioning members 310 are respectively arranged at both ends of the notch 210, and the number of positioning holes on each mounting profile 2000 is two. The two first positioning members 310 are used to cooperate with the positioning holes on the first clamping portion 2110 on one of the mounting profiles 2000, and the one second positioning member 320 is used to cooperate with the positioning hole on the first clamping portion 2110 on the other mounting profile 2000. For example, as shown in FIG. 2 , the two first positioning members 310 are respectively used to cooperate with the two positioning holes on the first profile 2100, and the second positioning member 320 is used to cooperate with one positioning hole on the second profile 2200. That is, when there are three mounting profiles 2000, the three mounting profiles 2000 can be connected to the power module 3000 through two power module mounting structures 1000, which not only reduces the number of power module mounting structures 1000 used, but also enables a frame-like structure to be formed between the two power module mounting structures 1000 and the three mounting profiles 2000.

[0060] By matching the first positioning member 310 of the plurality of positioning members 300 with a mounting profile 2000 and the second positioning member 320 with another mounting profile 2000, each power module mounting structure 1000 is connected to two mounting profiles 2000, thereby forming a frame-like structure between the power module mounting structure 1000 and the two mounting profiles 2000, which are not easily deformed after the two are assembled.

[0061] 4 and 5 , the power module mounting structure 1000 provided in some embodiments of the present application further includes a third mounting plate 400, which is connected to a side of the first mounting plate 100 away from the second mounting plate 200, and the extension direction of the third mounting plate 400 is opposite to the extension direction of the second mounting plate 200. The third mounting plate 400 is used to be electrically connected to the power module 3000.

[0062] The third mounting plate 400 can be made of a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, etc., so that the third mounting plate 400 is strong and firm, and is also easy to process. The embodiment of the present application does not impose any special restrictions on this.

[0063] The first mounting plate 100 and the third mounting plate 400 may be connected by welding, or may be integrally formed by stamping or the like.

[0064] Since the power module 3000 is grounded, by electrically connecting the third mounting plate 400 to the power module 3000, both the power module mounting structure 1000 and the power module 3000 can be grounded, making the use of the energy storage device safer.

[0065] 4 and 5, the third mounting plate 400 of the power module mounting structure 1000 provided in some embodiments of the present application is provided with a grounding nut 500. The grounding nut 500 is fixedly connected to the power module 3000 and is configured to be connected to a grounding wire.

[0066] The grounding nut 500 may be specifically made of a conductive material, and the grounding nut 500 is connected to a grounding wire, and the other end of the grounding wire away from the grounding nut 500 is connected to the ground.

[0067] The power module mounting structure 1000 is connected to the ground through the grounding nut 500, so that the power module mounting structure 1000 is not easily charged, making the use of the energy storage device safer. At the same time, since the grounding nut 500 is in surface contact with the grounding wire, the grounding effect of the power module mounting structure 1000 is better, and the equipotential effect with the power module 3000 is also better.

[0068] Referring to FIG. 4 and FIG. 5 , the third mounting plate 400 of the power module mounting structure 1000 provided in some embodiments of the present application is parallel to the second mounting plate 200. By setting the third mounting plate 400 to be parallel to the second mounting plate 200, the grounding nut 500 set on the third mounting plate 400 can be better grounded. At the same time, the gravity distribution of the entire power module mounting structure 1000 is also more reasonable, which is convenient for holding and installation, thereby reducing the difficulty of installation.

[0069] Please refer to FIG. 4 . In some embodiments of the present application, the angle θ between the first mounting plate 100 and the second mounting plate 200 of the power module mounting structure 1000 satisfies the condition: 90°≤θ<180°.

[0070] The included angle θ between the first mounting plate 100 and the second mounting plate 200 is the included angle between the second mounting plate 200 provided with the positioning member 300 on one side and the first mounting plate 100 on the side close to the positioning member 300 as shown in FIG. 4 .

[0071] By setting the angle θ between the first mounting plate 100 and the second mounting plate 200 to be greater than or equal to 90° and less than 180°, when the mounting profile 2000 and the power module mounting structure 1000 are installed, the installation space enclosed by the first mounting plate 100 and the second mounting plate 200 is a right-angle or obtuse-angle installation space, thereby making the installation space larger, facilitating the adjustment and alignment of the mounting profile 2000 and the mounting bracket 4000 of the energy storage device in the installation space, and making the installation process more convenient.

[0072] It should be noted that, since the width dimension of the second mounting plate 200 is small, that is, the dimension along the yy' direction in FIG. 4 is small, and since the surface of the mounting bracket 4000 with the mounting hole is perpendicular to the first side surface 3100 (shown in FIG. 2) of the power module 3000, it is necessary to set the angle θ between the first mounting plate 100 and the second mounting plate 200 to be greater than or equal to 90°, so that the angle of the mounting space enclosed by the first mounting plate 100 and the second mounting plate 200 is greater than or equal to 90°, so that the surface of the mounting bracket 4000 with the mounting hole can be easily installed in the mounting space. In order to simultaneously consider the compactness of the entire power module mounting structure 1000, the angle θ between the first mounting plate 100 and the second mounting plate 200 is set to be less than 180°, so that the first mounting plate 100 and the second mounting plate 200 are arranged at an angle, so that compared with the structure in which the first mounting plate 100 and the second mounting plate 200 are arranged in parallel along the width direction of the second mounting plate 200, the structure of the entire mounting structure is more compact. In some of the embodiments, the angle θ between the first mounting plate 100 and the second mounting plate 200 may be 90°, 95°, 100°, 120°, 130°, 170°, 172°, 175° or 179°, etc.

[0073] In some embodiments, the angle θ between the first mounting plate 100 and the second mounting plate 200 satisfies the condition: 95°≤θ≤120°. Thus, the first mounting plate 100 and the second mounting plate 200 form a bend approximately at 90°, which is more convenient for the user to manually deflect and use tools or manual support, and the installation is more convenient.

[0074] In some embodiments, the angle θ between the first mounting plate 100 and the second mounting plate 200 is 95°. In other embodiments, the angle θ between the first mounting plate 100 and the second mounting plate 200 is 120°. In still other embodiments, the angle θ between the first mounting plate 100 and the second mounting plate 200 is 110°.

[0075] Please refer to Figures 1 and 2. The present application also provides an energy storage device, which includes the power module mounting structure 1000 described in any of the above embodiments, and also includes a mounting profile 2000 and a power module 3000; the mounting profile 2000 is installed on the power module 3000, and the snap-in groove 110 and the notch 210 are used for snap-fitting and mounting the mounting profile 2000. At least one of the above technical effects can be achieved through the energy storage device.

[0076] Since the first mounting plate 100 and the second mounting plate 200 of the energy storage device provided in the present application are arranged at an angle, and the first mounting plate 100 is provided with a snap-fitting groove 110, and the second mounting plate 200 is provided with a notch 210 connected to the snap-fitting groove 110, the snap-fitting groove 110 and the notch 210 can snap-fit ​​the mounting profile 2000 on the power module 3000. Therefore, during the installation process, the user can manually rotate the power module mounting structure 1000, so that the accommodating space formed by the notch 210 and the snap-fitting groove 110 can snap-fit ​​the mounting profile 2000 more easily, thereby making it more convenient and time-saving to install and fix the power module 3000 of the energy storage device with a relatively cramped installation space. Moreover, since the first mounting plate 100 and the second mounting plate 200 are arranged at an angle, compared with the structure in which the first mounting plate 100 and the second mounting plate 200 are arranged in parallel along the width direction of the second mounting plate 200, the size occupied by the power module mounting structure 1000 along the width direction of the second mounting plate 200, that is, along the yy' direction in FIG. 1 is smaller, and the entire power module mounting structure 1000 is more compact, so that the power module mounting structure 1000 can be more easily inserted into the narrow installation space between the battery cabinet 5000 and the power module 3000 shown in FIG. 1, thereby making it more convenient and time-saving to install and fix the power module 3000 of the energy storage device with a relatively cramped installation space; and it can also make it possible to reserve a smaller installation space between the battery cabinet 5000 and the power module 3000 along the yy' direction in FIG. 1 when designing the energy storage device, so that the structure of the entire energy storage device is relatively compact, thereby increasing the space utilization rate of the energy storage device.

[0077] Please refer to FIG. 1 and FIG. 2 . The energy storage device provided in some embodiments of the present application further includes a mounting bracket 4000 . The mounting bracket 4000 is mounted on the power module 3000 . The mounting profile 2000 and the power module mounting structure 1000 are both connected to the mounting bracket 4000 .

[0078] The mounting bracket 4000 is made of a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, etc., so that the mounting bracket 4000 is strong and firm, and is also easy to process. The embodiment of the present application does not impose any special restrictions on this.

[0079] The mounting bracket 4000 surrounds the outer circumference of the power module 3000, and the mounting bracket 4000 is made of a relatively thin material. The mounting bracket 4000 is used as an intermediate piece, so that it is convenient to process the mounting holes connected to the mounting profile 2000 on the mounting bracket 4000, without directly processing the mounting holes connected to the mounting profile 2000 on the power module 3000, and the processing process is relatively simple. The power module mounting structure 1000, the mounting profile 2000 and the mounting bracket 4000 are fixedly connected by the intermediate piece, so that the mounting profile 2000 can finally support the power module 3000.

[0080] In some of the embodiments, the energy storage device further includes a connecting piece (not shown in the figure), and a positioning hole is configured on the mounting profile 2000; the mounting bracket 4000 is configured with a mounting hole, and the positioning piece 300 passes through the positioning hole on the mounting profile 2000 and the mounting hole on the mounting bracket 4000, and then is connected to the connecting piece, thereby realizing a fixed connection among the power module mounting structure 1000, the mounting profile 2000 and the mounting bracket 4000, which is relatively simple and convenient. Specifically, the connecting piece can be a nut.

[0081] Please refer to Figure 1. The energy storage device provided in some embodiments of the present application also includes a battery cabinet 5000. The battery cabinet 5000 is arranged at an interval from the power module 3000, and there are multiple battery cabinets 5000. The multiple battery cabinets 5000 are connected in parallel to each other. The battery cabinets 5000 are used to reduce peak loads and fill valleys and adjust power loads.

[0082] According to some embodiments of the present application, referring to FIG. 1 to FIG. 5 , the present application provides a power module mounting structure 1000 and an energy storage device. The power module mounting structure 1000 includes a first mounting plate 100, a second mounting plate 200 and a third mounting plate 400 connected in sequence. A clamping groove 110 is configured on the first mounting plate 100; the second mounting plate 200 is arranged at an angle to the first mounting plate 100, and a notch 210 is configured on the second mounting plate 200 and is arranged opposite to the clamping groove 110, and the notch 210 is connected to the clamping groove 110; the clamping groove 110 and the notch 210 are used to clamp the mounting profile 2000 installed on the power module 3000. The third mounting plate 400 is connected to the side of the first mounting plate 100 away from the second mounting plate 200, and the extension direction of the third mounting plate 400 is opposite to the extension direction of the second mounting plate 200, and the third mounting plate 400 is used to be connected to the power module 3000 at the same potential. The angle θ between the first mounting plate 100 and the second mounting plate 200 satisfies the condition: 90°≤θ<180°. At the same time, the second mounting plate 200 is provided with a plurality of positioning members 300 spaced apart along the length direction of the second mounting plate 200, the plurality of positioning members 300 includes a first positioning member 310, the first positioning member 310 is arranged at the notch 210, and the side of the second mounting plate 200 away from the notch 210 is provided with an extension protruding outward along its own length direction; the plurality of positioning members 300 also includes a second positioning member 320, the second positioning member 320 is arranged at the extension. The first positioning member 310 is used to cooperate with one mounting profile 2000, and the second positioning member 320 is used to cooperate with another mounting profile 2000.

[0083] By such arrangement, when the energy storage device equipped with the power module mounting structure 1000 is installing the power module 3000, since the first mounting plate 100 and the second mounting plate 200 are arranged at an angle, and the first mounting plate 100 is provided with a clamping groove 110, and the second mounting plate 200 is provided with a notch 210 connected with the clamping groove 110, the clamping groove 110 and the notch 210 can clamp the mounting profile 2000 on the power module 3000. Therefore, during the installation process, the power module mounting structure 1000 can be rotated, so that the accommodation space formed by the notch 210 and the clamping groove 110 can be clamped with the mounting profile 2000 more easily, thereby making it more convenient and time-saving to install and fix the power module 3000 of the energy storage device with a relatively cramped installation space. Moreover, since the first mounting plate 100 and the second mounting plate 200 are arranged at an angle, compared with the structure in which the first mounting plate 100 and the second mounting plate 200 are arranged in parallel along the width direction of the second mounting plate 200, the power module mounting structure 1000 provided in the present application occupies a smaller dimension along the width direction of the second mounting plate 200, that is, along the yy' direction in Figure 1, and the entire power module mounting structure 1000 is relatively compact, so that the power module mounting structure 1000 can be more easily inserted into the narrow installation space between the battery cabinet 5000 and the power module 3000 shown in Figure 1, thereby making it more convenient and time-saving to install and fix the power module 3000 of the energy storage device with a relatively cramped installation space; and it can also make it possible to reserve a smaller installation space between the battery cabinet 5000 and the power module 3000 along the yy' direction in Figure 1 when designing the energy storage device, so that the structure of the entire energy storage device is relatively compact, thereby increasing the space utilization rate of the energy storage device. Since the power module 3000 is grounded, by connecting the third mounting plate 400 and the power module 3000 to the same potential, the power module mounting structure 1000 and the power module 3000 can both achieve the grounding effect, making the use of the energy storage device safer. By setting the angle θ between the first mounting plate 100 and the second mounting plate 200 to be greater than or equal to 90° and less than 180°, when the mounting profile 2000 and the power module mounting structure 1000 are installed, the installation space enclosed by the first mounting plate 100 and the second mounting plate 200 is a right-angle or obtuse-angle installation space, thereby making the installation space larger, facilitating the adjustment and alignment of the mounting profile 2000 and the mounting bracket 4000 of the energy storage device in the installation space, and making the installation process more convenient.By matching the first positioning member 310 among the multiple positioning members 300 with a mounting profile 2000 and the second positioning member 320 with another mounting profile 2000, each power module mounting structure 1000 is connected to two mounting profiles 2000, thereby forming a frame-like structure between the power module mounting structure 1000 and the two mounting profiles 2000, which are not easily deformed after the two are assembled.
