Description

Technical Field

[0001] The utility model relates to the technical field of inverters, and more specifically, to a fixing device, an inverter, and an energy storage system. Background Art

[0002] Currently, in household energy storage and inverter products, to ensure stability during transportation, module devices in the inverter are often installed and fixed. Generally, sheet metal bending parts with a certain height are fixed to the mounting plate by bolts.

[0003] However, the heights of different module devices are generally different. In addition, to maintain the non-uniqueness of incoming materials and share the supply risk, the number of incoming materials for the same module device is not less than two, and the height dimensions of products from each manufacturer are generally not unified. That is to say, even for the same module device, there may be a situation where the heights are inconsistent. Therefore, it is necessary to process sheet metal bending parts with multiple heights, increasing the cost of the inverter. Summary of the Utility Model

[0004] The embodiments of the present utility model aim to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of the embodiments of the present utility model provides a fixing device.

[0006] A second aspect of the embodiments of the present utility model provides an inverter.

[0007] A third aspect of the embodiments of the present utility model provides an energy storage system.

[0008] In view of this, according to the first aspect of the embodiments of the present utility model, a fixing device for an inverter is provided. The inverter includes module devices. The fixing device includes: a housing component provided with at least two adjusting parts having different heights; an adjusting member capable of cooperatively connecting with any one of the at least two adjusting parts. Based on the cooperative connection between the adjusting member and any one of the adjusting parts, the adjusting member and the housing component enclose a housing space for housing the module devices.

[0009] The fixing device provided by the embodiments of the present utility model includes a housing component and an adjusting member. Specifically, the housing component is provided with at least two adjusting parts having different heights, and the adjusting member is capable of cooperatively connecting with any one of the at least two adjusting parts. It can be understood that when the adjusting member cooperatively connects with adjusting parts of different heights, the height at which the adjusting member is located is different.

[0010] When the adjusting member is cooperatively connected to any one of the adjusting parts, the adjusting member and the accommodating assembly enclose an accommodating space. Since the heights of at least two adjusting parts are different, when the adjusting member is cooperatively connected to the adjusting parts with different heights, the height of the formed accommodating space is different, so that module devices with different heights can be compatible, making the fixing device have high compatibility and improving the stability and reliability of module devices with various heights during transportation and of the inverter during use.

[0011] Specifically, when the heights of multiple module devices are different, or when the same module device has different heights from different manufacturers, the height of the accommodating space can be adjusted by cooperatively connecting the adjusting member to the adjusting parts with different heights, so as to match module devices with different heights, without designing different sheet metal bending parts for module devices with different heights. That is to say, one fixing device can be used to be compatible with and match module devices with various heights, which is beneficial to reducing the mold cost of the fixing device and further reducing the production cost of the inverter.

[0012] In addition, the fixing device provided by the above technical solution of the present utility model further has the following additional technical features:

[0013] In some technical solutions, optionally, each adjusting part includes an adjusting hole; the adjusting member includes a moving part, and the moving part can move into or out of any one of the adjusting holes.

[0014] In this technical solution, it is defined that each adjusting part includes an adjusting hole, that is to say, at least two adjusting holes with different heights are provided on the accommodating assembly.

[0015] The adjusting member includes a moving part, and the moving part can move into or out of any one of the adjusting holes to adjust the height of the accommodating space according to the height of the module device, so as to achieve the purpose of being compatible with module devices with different heights, improve the stability and reliability of module devices with various heights during transportation and of the inverter during use. At the same time, one fixing device can be used to be compatible with and match module devices with various heights, which is beneficial to reducing the mold cost of the fixing device and further reducing the production cost of the inverter.

[0016] In addition, adjusting the height of the accommodating space by moving the moving part into or out of the adjusting hole is beneficial to improving the adjusting speed and realizing the quick positioning and installation of the module device in the inverter. Moreover, it is also beneficial to improving the connection stability between the adjusting member and the accommodating assembly, and further improving the reliability of the inverter during transportation and during use.

[0017] In some technical solutions, optionally, any two adjacent adjusting holes are communicated, and the moving part can move from one adjusting hole into another adjusting hole.

[0018] In this technical solution, it is defined that any two adjacent adjustment holes are connected. Specifically, when the fixing device matches module devices of different heights, the moving part of the adjusting part needs to be moved out of one adjustment hole and into another adjustment hole so that the height of the changed accommodation space can match the module device.

[0019] Since any two adjacent adjustment holes are connected, when the adjusting part adjusts the height of the accommodation space, it is not necessary to move out of one adjustment hole. That is, the moving part can be directly moved from one adjustment hole into another adjustment hole, which is beneficial to quickly adjust the height of the accommodation space. Furthermore, while the fixing device is compatible with module devices of different heights, the installation efficiency of the inverter can be improved.

[0020] In some technical solutions, optionally, the moving part can move between a first position and a second position in any adjustment hole; wherein, based on the moving part being located at the first position, along the height direction of the accommodation space, the side surface of the moving part facing away from the accommodation space can abut against the hole wall of the adjustment hole; based on the moving part being located at the second position, the moving part can be moved from one adjustment hole into another adjustment hole.

[0021] In this technical solution, it is defined that the moving part can move between a first position and a second position in any adjustment hole. Optionally, the moving part can flip in any adjustment hole so that the moving part moves from the first position to the second position, or from the second position to the first position.

[0022] Specifically, when the moving part is located at the first position, along the height direction of the accommodation space, the side surface of the moving part facing away from the accommodation space can abut against the hole wall of the adjustment hole, that is, the top surface of the moving part abuts against the top of the hole wall of the adjustment hole, thereby realizing reliable fixation of the module device.

[0023] When it is necessary to adjust the height of the accommodation space, the moving part is flipped from the first position to the second position, and the moving part is moved from this adjustment hole into another adjustment hole corresponding to the height of the module device. It can be understood that when the moving part moves into the target adjustment hole, the moving part is flipped from the second position to the first position again, and the top surface of the moving part abuts against the top of the hole wall of the adjustment hole to fix the module device. Thus, while quickly adjusting the height of the accommodation space and improving the compatibility of the fixing device with module devices of different heights, it is beneficial to realize reliable fixation of the fixing device to the module device and improve the stability of the inverter during transportation and use.

[0024] It can be understood that the width of the moving part is less than or equal to the height of the adjustment hole, so that the moving part can flip in the adjustment hole.

[0025] In some technical solutions, optionally, the accommodating component is further provided with a guiding channel, and any two adjacent adjusting holes are communicated through the guiding channel, and the moving part can move from one adjusting hole into another adjusting hole through the guiding channel.

[0026] In this technical solution, it is defined that the accommodating component is further provided with a guiding channel. Specifically, any two adjacent adjusting holes are communicated through the guiding channel. That is to say, when the height of the accommodating space needs to be adjusted, there is no need to move out from one adjusting hole. That is, the moving part can directly move from one adjusting hole into another adjusting hole through the guiding channel, which is beneficial to realizing the rapid adjustment of the height of the accommodating space. Furthermore, while the fixing device is compatible with module devices of different heights, the installation efficiency of the inverter can be improved.

[0027] In some technical solutions, optionally, the width of the moving part is greater than the width of the guiding channel; and / or the thickness of the moving part is less than the width of the guiding channel.

[0028] In this technical solution, the width of the moving part is greater than the width of the guiding channel. When the moving part is in the first position, the top surface of the moving part can abut against the top of the hole wall of the adjusting hole, realizing effective limiting of the adjusting part and improving the reliability of the fixing device for installing and fixing the module device.

[0029] The thickness of the moving part is less than the width of the guiding channel, so that when the moving part is flipped from the first position to the second position, the moving part can pass through the guiding channel and move into the corresponding adjusting hole, which is beneficial to further realizing the rapid adjustment of the height of the accommodating space. Furthermore, while the fixing device is compatible with module devices of different heights, the installation efficiency of the inverter can be improved.

[0030] In some technical solutions, optionally, the adjusting part includes a body and a limiting part. Among them, the moving part is arranged at the end of the body, and the limiting part is arranged at the end of the moving part far away from the body. Based on the moving part moving into any adjusting hole, the body and the accommodating component enclose an accommodating space, and the limiting part is located outside the accommodating space.

[0031] In this technical solution, it is defined that the adjusting part includes a body and a limiting part. Specifically, the moving part is arranged at the end of the body, and the limiting part is arranged at the end of the moving part far away from the body. That is to say, the moving part is located between the limiting part and the body.

[0032] When the moving part moves into any adjusting hole, the limiting part is located outside the accommodating space, so as to limit the adjusting part in the inner and outer directions of the accommodating space, that is, the length direction of the adjusting part, further improving the reliability of the fixing device for fixing the module device, and then improving the stability of the inverter during transportation and use.

[0033] Optionally, the width of the limiting part is greater than the width of the adjustment hole to effectively limit the adjusting part.

[0034] Optionally, the body, the limiting part and the moving part are of an integral structure.

[0035] In some technical solutions, optionally, the adjustment holes of each adjustment part include a first adjustment hole and a second adjustment hole, and the first adjustment hole and the second adjustment hole are symmetrically distributed on opposite sides of the accommodation space; the number of moving parts is two, and the two moving parts are respectively located at opposite ends of the body. Based on the cooperation and connection between the adjusting part and any one of the adjustment parts, one of the moving parts is located in the first adjustment hole, and the other moving part is located in the second adjustment hole.

[0036] In this technical solution, it is defined that the adjustment holes of each adjustment part include a first adjustment hole and a second adjustment hole. Specifically, the first adjustment hole and the second adjustment hole are symmetrically distributed on opposite sides of the accommodation space, that is to say, the first adjustment hole and the second adjustment hole are at the same height.

[0037] The two moving parts are respectively located at opposite ends of the body. When the adjusting part is cooperatively connected with any one of the adjustment parts, one of the moving parts moves into the first adjustment hole of the adjustment part, and the other moving part moves into the second adjustment hole of the adjustment part, so as to make the module device be fixed with balanced force while realizing the adjustable height of the accommodation space, which is beneficial to further extend the service life of the inverter.

[0038] It can be understood that when the fixing device matches module devices of other heights, the two moving parts are respectively moved into the first adjustment hole and the second adjustment hole of the corresponding adjustment part to realize the adjustment of the height of the accommodation space, improve the compatibility of the fixing device with module devices of different heights, and do not require replacing a new fixing device due to the problem of substitute materials, which is beneficial to reducing the production cost of the inverter.

[0039] In some technical solutions, optionally, the fixing device further includes a buffer, and the buffer is arranged on one side of the adjusting part located in the accommodation space.

[0040] In this technical solution, it is defined that the fixing device further includes a buffer. Specifically, the buffer is arranged on one side of the adjusting part located in the accommodation space, that is to say, when installing and fixing the module device, the buffer contacts the module device, that is, the contact with the module device belongs to "soft touching hard", so as to effectively avoid the problem of damage to the module device caused by the direct contact between the adjusting part and the module device during the transportation or use of the inverter. While playing a role in fixing the module device, it improves the safety during the installation of the module device, which is beneficial to extending the service life of the inverter.

[0041] Optionally, the buffer is a flexible gasket.

[0042] In some technical solutions, optionally, the fixing device further includes an adhesive member, and the buffer member is connected to the adjusting member through the adhesive member.

[0043] In this technical solution, it is defined that the fixing device further includes an adhesive member. Specifically, the buffer member is fixedly connected to the adjusting member through the adhesive member. Thus, compared with using structures such as screws to connect the buffer member and the adjusting member, it can effectively avoid scratching the module devices by structures such as screws. While achieving reliable fixation of the buffer member, it is beneficial to further extend the service life of the inverter and improve the reliability of the inverter.

[0044] In some technical solutions, optionally, the accommodating assembly includes a bottom plate and an accommodating plate. Among them, the first end of the accommodating plate is connected to the bottom plate, and at least two adjusting portions are provided at the second end of the accommodating plate. Based on the adjusting member being cooperatively connected with any one of the adjusting portions, the adjusting member, the accommodating plate, and the bottom plate enclose an accommodating space.

[0045] In this technical solution, it is defined that the accommodating assembly includes a bottom plate and an accommodating plate. Specifically, one end of the accommodating plate is connected to the chassis. Optionally, a first threaded hole is provided at one end of the accommodating plate, and a second threaded hole is provided on the bottom plate. The accommodating assembly further includes a screw, and the screw passes through the first threaded hole and the second threaded hole respectively to connect one end of the accommodating plate to the chassis.

[0046] At least two adjusting portions are provided at the other end of the accommodating plate. When the adjusting member is cooperatively connected with any one of the adjusting portions, the adjusting member, the accommodating plate, and the bottom plate enclose an accommodating space. Since the heights of at least two adjusting portions are different, when the adjusting member is cooperatively connected with adjusting portions of different heights, the height of the formed accommodating space is different. Furthermore, it can be compatible with module devices of different heights, making the fixing device have high compatibility and improving the stability and reliability of module devices of various heights during transportation and the inverter during use.

[0047] In addition, when the heights of multiple module devices are different, or when the same module device has different heights from different manufacturers, the height of the accommodating space can be adjusted by making the adjusting member cooperatively connected with adjusting portions of different heights, so as to match module devices of different heights. There is no need to design different sheet metal bending parts for module devices of different heights. That is to say, one fixing device can be compatible and match module devices of multiple heights, which is beneficial to reducing the mold cost of the fixing device and further reducing the production cost of the inverter.

[0048] Specifically, when installing the module device, the first step: install the module device on the bottom plate; the second step: adjust the adjusting member to the corresponding adjusting portion position according to the height of the module device; the third step: tighten the fixing bolt to connect the accommodating plate and the bottom plate.

[0049] Optionally, the accommodating plate includes a first plate body and a second plate body, the first plate body and the second plate body are arranged oppositely and are respectively connected to the bottom plate, a first adjustment hole is provided on the first plate body, and a second adjustment hole is provided on the second plate body.

[0050] According to the second aspect of the present invention, an inverter is provided, which includes the fixing device provided in any of the above technical solutions, and thus has all the beneficial technical effects of the fixing device, which will not be elaborated here.

[0051] Furthermore, the inverter further includes a module device, and the module device is placed in the accommodating space.

[0052] The inverter provided by the embodiment of the present invention includes a module device and a fixing device. Specifically, the accommodating assembly is provided with at least two adjusting parts with different heights, and the adjusting member can be cooperatively connected with any one of the at least two adjusting parts. It can be understood that when the adjusting member is cooperatively connected with the adjusting parts with different heights, the heights are different.

[0053] When the adjusting member is cooperatively connected with any one of the adjusting parts, the adjusting member and the accommodating assembly enclose to form an accommodating space. Since the heights of the at least two adjusting parts are different, when the adjusting member is cooperatively connected with the adjusting parts with different heights, the heights of the formed accommodating spaces are different, and thus different-height module devices can be compatible, making the fixing device have high compatibility and improving the stability and reliability of various-height module devices during transportation and the inverter during use.

[0054] Specifically, when the heights of multiple module devices are different, or the same module device has different heights from different manufacturers, the height of the accommodating space can be adjusted by making the adjusting member cooperatively connected with the adjusting parts with different heights, so as to match different-height module devices. There is no need to design different sheet metal bending parts for different-height module devices. That is to say, one fixing device can be compatible with and match multiple-height module devices, which is beneficial to reducing the mold cost of the fixing device and further reducing the production cost of the inverter.

[0055] According to the third aspect of the present invention, an energy storage system is provided, which includes the fixing device or the inverter provided in any of the above technical solutions, and thus has all the beneficial technical effects of the fixing device or the inverter, which will not be elaborated here.

Detailed implementation manners

[0076] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0077] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0078] Next, refer to Figures 1 to 16 to describe the fixing device 100, inverter and energy storage system provided according to some embodiments of the present utility model.

[0079] In an embodiment according to the present application, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16As shown, a fixing device 100 for an inverter is proposed. The inverter includes a module device 200. The fixing device 100 includes: a housing component 110 provided with at least two adjusting parts 111 having different heights; an adjusting member 120 capable of being cooperatively connected with any one of the at least two adjusting parts 111. Based on the cooperative connection between the adjusting member 120 and any one of the adjusting parts 111, the adjusting member 120 and the housing component 110 enclose a housing space 130 for housing the module device 200.

[0080] The fixing device 100 provided by the embodiment of the present utility model includes a housing component 110 and an adjusting member 120. Specifically, the housing component 110 is provided with at least two adjusting parts 111 having different heights, and the adjusting member 120 can be cooperatively connected with any one of the at least two adjusting parts 111. It can be understood that when the adjusting member 120 is cooperatively connected with the adjusting parts 111 of different heights, the height at which it is located is different.

[0081] When the adjusting member 120 is cooperatively connected with any one of the adjusting parts 111, the adjusting member 120 and the housing component 110 enclose a housing space 130. Since the at least two adjusting parts 111 have different heights, when the adjusting member 120 is cooperatively connected with the adjusting parts 111 of different heights, the height of the enclosed housing space 130 is different. Furthermore, module devices 200 of different heights can be compatible, making the fixing device 100 have high compatibility and improving the stability and reliability of module devices 200 of various heights during transportation and the inverter during use.

[0082] Specifically, when the heights of multiple module devices 200 are different, or when the same module device 200 has different heights from different manufacturers, the height of the housing space 130 can be adjusted by making the adjusting member 120 cooperatively connected with the adjusting parts 111 of different heights, so as to match module devices 200 of different heights. There is no need to design different sheet metal bending parts for module devices 200 of different heights. That is to say, one fixing device 100 can be used to be compatible with and match module devices 200 of various heights, which is beneficial to reducing the mold cost of the fixing device 100 and further reducing the production cost of the inverter.

[0083] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13, Figure 14 , Figure 15 and Figure 16 As shown in Figure 16 , in some embodiments, optionally, each adjusting portion 111 includes an adjusting hole 140; the adjusting member 120 includes a moving portion 121, and the moving portion 121 can move into or out of any one of the adjusting holes 140.

[0084] In this embodiment, it is defined that each adjusting portion 111 includes an adjusting hole 140, that is to say, at least two adjusting holes 140 with different heights are provided on the accommodating component 110.

[0085] The adjusting member 120 includes a moving portion 121, and the moving portion 121 can move into or out of any one of the adjusting holes 140 to adjust the height of the accommodating space 130 according to the height of the module device 200, so as to achieve the purpose of being compatible with module devices 200 of different heights, and improve the stability and reliability of module devices 200 of various heights during transportation and the inverter during use. At the same time, using a fixing device 100 can be compatible with and match module devices 200 of various heights, which is beneficial to reducing the mold cost of the fixing device 100, and further reducing the production cost of the inverter.

[0086] In addition, by moving the moving portion 121 into or out of the adjusting hole 140 to adjust the height of the accommodating space 130, it is beneficial to improve the adjustment speed and realize the quick positioning and installation of the module device 200 in the inverter. Moreover, it is also beneficial to improve the connection stability between the adjusting member 120 and the accommodating component 110, and further improve the reliability of the inverter during transportation and use.

[0087] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown in Figure 16 , in some embodiments, optionally, any two adjacent adjusting holes 140 are communicated, and the moving portion 121 can move from one of the adjusting holes 140 into another adjusting hole 140.

[0088] In this embodiment, it is defined that any two adjacent adjustment holes 140 are communicated. Specifically, when the fixing device 100 matches module devices 200 with different heights, the moving part 121 of the adjusting member 120 needs to be moved out of one of the adjustment holes 140 and moved into another adjustment hole 140, so that the height of the changed accommodation space 130 can match the module device 200.

[0089] Since any two adjacent adjustment holes 140 are communicated, when the adjusting member 120 adjusts the height of the accommodation space 130, it is not necessary to move out of one of the adjustment holes 140. That is, the moving part 121 can be directly moved from one adjustment hole 140 into another adjustment hole 140, which is beneficial to quickly adjust the height of the accommodation space 130. Furthermore, while the fixing device 100 is compatible with module devices 200 with different heights, the installation efficiency of the inverter can be improved.

[0090] As Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 9 、 Figure 13 and Figure 15 As shown in

[0091] In this embodiment, it is defined that the moving part 121 can move between a first position and a second position in any one of the adjustment holes 140. Optionally, the moving part 121 can flip in any one of the adjustment holes 140, so that the moving part 121 moves from the first position to the second position, or from the second position to the first position.

[0092] Specifically, when the moving part 121 is in the first position, along the height direction of the accommodation space 130, the side surface of the moving part 121 facing away from the accommodation space 130 can abut against the hole wall of the adjustment hole 140. That is, the top surface of the moving part 121 abuts against the top of the hole wall of the adjustment hole 140, thereby realizing reliable fixation of the module device 200.

[0093] When it is necessary to adjust the height of the accommodation space 130, the moving part 121 is flipped from the first position to the second position. The moving part 121 moves into another adjustment hole 140 corresponding to the height of the module device 200 through the adjustment hole 140. It can be understood that when the moving part 121 moves into the target adjustment hole 140, the moving part 121 is flipped from the second position to the first position again, and the top surface of the moving part 121 abuts against the top of the hole wall of the adjustment hole 140 to fix the module device 200. Therefore, it is possible to quickly adjust the height of the accommodation space 130, improve the compatibility of the fixing device 100 with module devices 200 of different heights, and at the same time, facilitate the reliable fixing of the fixing device 100 to the module device 200, and improve the stability of the inverter during transportation and use.

[0094] It can be understood that the width of the moving part 121 is less than or equal to the height of the adjustment hole 140, so that the moving part 121 can be flipped within the adjustment hole 140.

[0095] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 And Figure 16 As shown in

[0096] In this embodiment, it is defined that the accommodation component 110 is further provided with a guiding channel 112. Specifically, any two adjacent adjustment holes 140 are connected through the guiding channel 112. That is to say, when it is necessary to adjust the height of the accommodation space 130, there is no need to move out from one of the adjustment holes 140. That is, the moving part 121 can directly move into another adjustment hole 140 from one of the adjustment holes 140 through the guiding channel 112, which is beneficial to quickly adjust the height of the accommodation space 130, and further enables the fixing device 100 to improve the installation efficiency of the inverter while being compatible with module devices 200 of different heights.

[0097] Such as Figure 10As shown, in some embodiments, optionally, the width of the moving part 121 is greater than the width of the guiding channel 112; and / or the thickness of the moving part 121 is less than the width of the guiding channel 112.

[0098] In this embodiment, the width a of the moving part 121 is greater than the width b of the guiding channel 112. When the moving part 121 is in the first position, the top surface of the moving part 121 can abut against the top of the hole wall of the adjusting hole 140, achieving effective limiting of the adjusting part 120 and improving the reliability of the fixing device 100 for installing and fixing the module device 200.

[0099] The thickness of the moving part 121 is less than the width b of the guiding channel 112, so that when the moving part 121 is flipped from the first position to the second position, the moving part 121 can pass through the guiding channel 112 and move into the corresponding adjusting hole 140, which is beneficial to further realizing the rapid adjustment of the height of the accommodating space 130. Furthermore, while the fixing device 100 is compatible with module devices 200 of different heights, the installation efficiency of the inverter can be improved.

[0100] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 and Figure 16 As shown, in some embodiments, optionally, the adjusting part 120 includes a main body 122 and a limiting part 123. Among them, the moving part 121 is arranged at the end of the main body 122, and the limiting part 123 is arranged at one end of the moving part 121 away from the main body 122. Based on the moving part 121 moving into any one of the adjusting holes 140, the main body 122 and the accommodating component 110 enclose an accommodating space 130, and the limiting part 123 is located outside the accommodating space 130.

[0101] In this embodiment, it is defined that the adjusting part 120 includes a main body 122 and a limiting part 123. Specifically, the moving part 121 is arranged at the end of the main body 122, and the limiting part 123 is arranged at one end of the moving part 121 away from the main body 122. That is to say, the moving part 121 is located between the limiting part 123 and the main body 122.

[0102] When the moving part 121 moves into any one of the adjusting holes 140, the limiting part 123 is located outside the accommodating space 130, so as to limit the adjusting part 120 in the inner and outer directions of the accommodating space 130, that is, in the length direction of the adjusting part 120, further improving the reliability of the fixing device 100 for fixing the module device 200, and thus improving the stability of the inverter during transportation and use.

[0103] Optionally, the width of the limiting part 123 is greater than the width of the adjusting hole 140 to effectively limit the adjusting part 120.

[0104] Optionally, the body 122, the limiting part 123 and the moving part 121 are of an integral structure.

[0105] As Figure 4 and Figure 10 shown, in some embodiments, optionally, the adjusting hole 140 of each adjusting part 111 includes a first adjusting hole 141 and a second adjusting hole 142, and the first adjusting hole 141 and the second adjusting hole 142 are symmetrically distributed on opposite sides of the accommodating space 130; the number of moving parts 121 is two, and the two moving parts 121 are respectively located at opposite ends of the body 122. Based on the cooperation connection between the adjusting part 120 and any one of the adjusting parts 111, one of the moving parts 121 is located in the first adjusting hole 141, and the other moving part 121 is located in the second adjusting hole 142.

[0106] In this embodiment, it is defined that the adjusting hole 140 of each adjusting part 111 includes a first adjusting hole 141 and a second adjusting hole 142. Specifically, the first adjusting hole 141 and the second adjusting hole 142 are symmetrically distributed on opposite sides of the accommodating space 130, that is to say, the first adjusting hole 141 and the second adjusting hole 142 are at the same height.

[0107] The two moving parts 121 are respectively located at opposite ends of the body 122. When the adjusting part 120 is cooperatively connected with any one of the adjusting parts 111, one of the moving parts 121 moves into the first adjusting hole 141 of this adjusting part 111, and the other moving part 121 moves into the second adjusting hole 142 of this adjusting part 111, so as to make the height of the accommodating space 130 adjustable and enable the module device 200 to be evenly stressed after being fixed, which is beneficial to further extending the service life of the inverter.

[0108] It can be understood that when the fixing device 100 matches the module device 200 with other heights, the two moving parts 121 are respectively moved into the first adjusting hole 141 and the second adjusting hole 142 of the corresponding adjusting part 111 to adjust the height of the accommodating space 130, improve the compatibility of the fixing device 100 with the module device 200 of different heights, and avoid the need to replace the new fixing device 100 due to the problem of replacement materials, which is beneficial to reducing the production cost of the inverter.

[0109] As Figure 4 and Figure 12 shown, in some embodiments, optionally, the fixing device 100 further includes a buffer member 150, and the buffer member 150 is disposed on one side of the adjusting member 120 located in the accommodating space 130.

[0110] In this embodiment, it is defined that the fixing device 100 further includes a buffer member 150. Specifically, the buffer member 150 is disposed on one side of the adjusting member 120 located in the accommodating space 130. That is to say, when the module device 200 is installed and fixed, the buffer member 150 contacts the module device 200, that is, the contact with the module device 200 belongs to "soft touching hard", so as to effectively avoid the problem that the module device 200 is damaged due to the direct contact between the adjusting member 120 and the module device 200 during the transportation or use of the inverter. While playing a role in fixing the module device 200, the safety during the installation of the module device 200 is improved, which is beneficial to extending the service life of the inverter.

[0111] Optionally, the buffer member 150 is a flexible gasket.

[0112] As Figure 4 shown, in some embodiments, optionally, the fixing device 100 further includes an adhesive member 160, and the buffer member 150 is connected to the adjusting member 120 through the adhesive member 160.

[0113] In this embodiment, it is defined that the fixing device 100 further includes an adhesive member 160. Specifically, the buffer member 150 is fixedly connected to the adjusting member 120 through the adhesive member 160. Thus, compared with using structures such as screws to realize the connection between the buffer member 150 and the adjusting member 120, it can effectively avoid the module device 200 being scratched by structures such as screws. While realizing the reliable fixation of the buffer member 150, it is beneficial to further extend the service life of the inverter and improve the reliability of the inverter.

[0114] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 and Figure 16As shown, in some embodiments, optionally, the accommodating component 110 includes a bottom plate 113 and an accommodating plate 114. Among them, the first end of the accommodating plate 114 is connected to the bottom plate 113, and at least two adjusting portions 111 are provided at the second end of the accommodating plate 114. Based on the cooperation connection between the adjusting member 120 and any one of the adjusting portions 111, the accommodating space 130 is formed by enclosing the adjusting member 120, the accommodating plate 114, and the bottom plate 113.

[0115] In this embodiment, it is defined that the accommodating component 110 includes a bottom plate 113 and an accommodating plate 114. Specifically, one end of the accommodating plate 114 is connected to the chassis. Optionally, a first threaded hole is provided at one end of the accommodating plate 114, a second threaded hole is provided on the bottom plate 113, and the accommodating component 110 further includes a screw, and the screw passes through the first threaded hole and the second threaded hole respectively to connect one end of the accommodating plate 114 to the chassis.

[0116] At least two adjusting portions 111 are provided at the other end of the accommodating plate 114. When the adjusting member 120 is cooperatively connected with any one of the adjusting portions 111, the adjusting member 120, the accommodating plate 114, and the bottom plate 113 enclose to form the accommodating space 130. Since the heights of the at least two adjusting portions 111 are different, when the adjusting member 120 is cooperatively connected with the adjusting portions 111 of different heights, the height of the formed accommodating space 130 is different. Furthermore, module devices 200 of different heights can be compatible, making the fixing device 100 have high compatibility and improving the stability and reliability of module devices 200 of various heights during transportation and the inverter during use.

[0117] In addition, when the heights of multiple module devices 200 are different, or when the same module device 200 has different heights from different manufacturers, the height of the accommodating space 130 can be adjusted by cooperatively connecting the adjusting member 120 with the adjusting portions 111 of different heights, so as to match module devices 200 of different heights. There is no need to design different sheet metal bending parts for module devices 200 of different heights. That is to say, one fixing device 100 can be compatible with and match module devices 200 of multiple heights, which is beneficial to reducing the mold cost of the fixing device 100 and further reducing the production cost of the inverter.

[0118] Specifically, when installing the module device 200, the first step: install the module device 200 on the bottom plate 113; the second step: adjust the adjusting member 120 to the corresponding position of the adjusting portion 111 according to the height of the module device 200; the third step: tighten the fixing bolt to connect the accommodating plate 114 and the bottom plate 113.

[0119] Optionally, the accommodating plate 114 includes a first plate body and a second plate body. The first plate body and the second plate body are arranged oppositely and are respectively connected to the bottom plate 113. A first adjusting hole 141 is provided on the first plate body, and a second adjusting hole 142 is provided on the second plate body.

[0120] According to a second aspect of the present utility model, an inverter is provided, which includes the fixing device 100 provided in any of the above embodiments, and thus has all the beneficial technical effects of the fixing device 100, which will not be elaborated here.

[0121] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown in

[0122] The inverter provided by the embodiment of the present utility model includes a module device 200 and a fixing device 100. Specifically, the accommodating assembly 110 is provided with at least two adjusting parts 111 with different heights, and the adjusting member 120 can be cooperatively connected with any one of the at least two adjusting parts 111. It can be understood that when the adjusting member 120 is cooperatively connected with the adjusting parts 111 with different heights, the heights at which it is located are different.

[0123] When the adjusting member 120 is cooperatively connected with any one of the adjusting parts 111, the adjusting member 120 and the accommodating assembly 110 enclose an accommodating space 130. Since the heights of the at least two adjusting parts 111 are different, when the adjusting member 120 is cooperatively connected with the adjusting parts 111 with different heights, the height of the formed accommodating space 130 is different, and thus the module devices 200 with different heights can be compatible, making the fixing device 100 have high compatibility and improving the stability and reliability of the module devices 200 with various heights during transportation and the inverter during use.

[0124] Specifically, when the heights of multiple module devices 200 are different, or when the same module device 200 has different heights from different manufacturers, the height of the accommodating space 130 can be adjusted by making the adjusting member 120 cooperatively connected with the adjusting parts 111 with different heights, so as to match the module devices 200 with different heights. There is no need to design different sheet metal bending parts for the module devices 200 with different heights. That is to say, one fixing device 100 can be used to be compatible with and match the module devices 200 with various heights, which is beneficial to reducing the mold cost of the fixing device 100 and further reducing the production cost of the inverter.
