Description

Technical Field

[0001] This application relates to the technical field of inverter devices, and particularly to an inverter device and an energy storage device. Background Art

[0002] Some inverter devices are relatively heavy, and usually clearance is provided at some positions at the bottom to set a handle position, so as to facilitate users to lift the inverter device when carrying or installing it. However, the handle position will occupy the space at the bottom of the inverter device. Due to space limitations, there is less layout space reserved for the handle position, resulting in a small area of the handle position, making it inconvenient for users to lift the inverter device and easy to touch the wiring terminals, causing damage to the wiring terminals. Utility Model Content

[0003] In view of this, this application provides an inverter device and an energy storage device, which are convenient for users to lift the inverter device and facilitate the protection of the wiring terminals when lifting the inverter device.

[0004] An embodiment of this application provides an inverter device. The inverter device includes a main unit. The main unit is provided with wiring terminals. The inverter device further includes a supporting member and a handle. The supporting member is detachably connected to the main unit. The supporting member has a connected fixing portion and a supported portion. The fixing portion is detachably connected to the main unit. The supported portion covers the wiring terminals. The side of the supported portion facing away from the wiring terminals is configured to be lifted by the user. The handle is connected to the main unit and is located on the opposite side of the main unit from the supporting member.

[0005] In the above embodiment, by providing a detachable supporting member, when it is necessary to carry and install the main unit, the supporting member is connected to the main unit. The user can grasp the handle on one side of the main unit with one hand and lift the supported portion of the supporting member on the opposite side of the handle with the other hand, which is convenient for the user to apply force on different sides of the main unit with both hands to stably lift the entire inverter device. The supported portion does not occupy the space of the main unit housing, so it is not limited by the layout space of the main unit, and can provide a larger lifting area for the user, facilitating the user to adjust the lifting position of the inverter device, and further facilitating the user to apply force to lift the inverter device. Moreover, the supported portion covers the wiring terminals, which can protect the wiring terminals when lifting the inverter device, and is beneficial to avoiding the obstruction of the wiring terminals or damage to the wiring terminals when the user lifts the inverter device.

[0006] In some embodiments of this application, the supported portion is provided with a clearance sub-portion and a support sub-portion. The clearance sub-portion is recessed on the side of the supported portion facing the wiring terminals. The clearance sub-portion covers the area where the wiring terminals are located. The support sub-portion is located within the clearance sub-portion. And the support sub-portion extends from the side of the supported portion facing away from the wiring terminals to the side facing the wiring terminals. The support sub-portion abuts against the main unit.

[0007] In the above embodiments, the receiving part is provided with an avoidance sub-part to avoid the position of the wiring terminal when covering the wiring terminal, which is beneficial to avoid the squeezing and damage of the wiring terminal by the supporting member. At the same time, the receiving part is provided with a supporting sub-part within the range of the avoidance sub-part. When the user lifts the inverter device, the supporting sub-part can support between the user and the host, providing a large lifting area for the user while maintaining the configuration of the avoidance sub-part, which is beneficial to avoid the deformation of the avoidance sub-part and the squeezing and damage of the wiring terminal.

[0008] In some embodiments of the present application, the fixing part includes a first connection hole. The host is provided with a second connection hole. The inverter device further includes a fastener. The fastener passes through the first connection hole and the second connection hole to connect the supporting member and the host.

[0009] In the above embodiments, the fastener is simultaneously connected to the supporting member and the host, making the supporting member fixed relative to the host, which is beneficial to improve the stability when the user lifts the inverter device.

[0010] In some embodiments of the present application, the fixing part further includes two groups of clamping sub-parts. The two groups of clamping sub-parts protrude from the side of the receiving part facing the wiring terminal. The two groups of clamping sub-parts are arranged oppositely and clamp the host.

[0011] In the above embodiments, by setting two groups of clamping sub-parts to clamp the host, on the one hand, it is convenient to correct the relative positions of the supporting member and the host before the fastener passes through the first connection hole and the second connection hole, so as to improve the assembly efficiency between the supporting member and the host; on the other hand, it can improve the connection stability between the supporting member and the host on the basis of the fastener connecting the supporting member and the host.

[0012] In some embodiments of the present application, the receiving part has a first wall and a second wall on the side facing the wiring terminal. There are two first walls and they are spaced apart relatively. There are two second walls and they are spaced apart relatively. Each second wall is connected between the two first walls. There are two groups of first connection holes. Each group of first connection holes is located on one first wall. Each group of clamping sub-parts is located on one second wall.

[0013] In the above embodiments, the two groups of first connection holes and the two groups of clamping sub-parts are arranged around the side of the receiving part facing the wiring terminal, so that the fixing part connects the receiving part and the host in multiple directions, thereby improving the assembly stability between the supporting member and the host, and facilitating the user to lift the inverter device.

[0014] In some embodiments of the present application, the supporting member is an elastic member.

[0015] In the above embodiments, the supporting member can produce elastic deformation when subjected to a force, thereby absorbing the applied force. On the one hand, it can provide buffering for the host to protect the host, especially the plug-in terminal; on the other hand, it provides buffering for the user, so as to improve the feel when the user lifts the inverter device.

[0016] In some embodiments of the present application, the main body is provided with a bottom wall and side walls. The bottom wall is provided with a terminal block. There are two side walls which are arranged opposite to each other. Each side wall is adjacent to the bottom wall. Each side wall is provided with a handle.

[0017] In the above embodiments, the supporting member and the handle are arranged on two adjacent sides of the main body. When the user lifts the inverter device through the supporting member and the handle, it is convenient to control the posture of the inverter device from two intersecting directions, so as to facilitate maintaining the stability when the user lifts the inverter device. And handles are provided on the side walls on the opposite sides of the main body, which is convenient for multiple users to lift the inverter device at the same time to better control the posture of the inverter device, and is beneficial to more stable lifting of the inverter device.

[0018] In some embodiments of the present application, the handle includes a connecting seat and a handle. The connecting seat is connected to the main body. The handle is rotatably connected to the connecting seat. The handle can rotate between a storage position and a working position. When the handle rotates to the storage position, it is closer to the main body than when it rotates to the working position.

[0019] In the above embodiments, the handle is connected to the main body through the connecting seat, and the inverter device is carried by holding the handle. And the handle can rotate and switch between the storage position and the working position. When the handle is needed, the handle can be in the working position, so that the handle is away from the main body, thereby providing enough space beside the handle for the user to hold the handle; when the handle is not needed, the handle can be in the storage position to reduce the space occupied by the handle beside the main body, which is beneficial to reducing the overall occupied space of the inverter device.

[0020] In some embodiments of the present application, the connecting seat is provided with a limiting portion. When the handle rotates from the storage position to the working position, the limiting portion stops the handle from further rotating.

[0021] In the above embodiments, by setting the limiting portion, the position of the handle relative to the main body when the handle rotates to the working position is restricted, so as to fix the handle relative to the main body when the user holds the handle to carry the inverter device, thereby improving the stability of the inverter device when the user carries the inverter device.

[0022] In some embodiments of the present application, the handle is provided with a first heat dissipation opening. The main body is provided with a second heat dissipation opening. When the handle rotates to the storage position, at least part of the first heat dissipation opening is opposite to at least part of the second heat dissipation opening.

[0023] In the above embodiments, the handle is provided with the first heat dissipation opening to reduce the blockage of the second heat dissipation opening, which is beneficial to reducing the influence on the heat dissipation efficiency of the main body exhausting heat outward through the second heat dissipation opening while reducing the overall occupied space of the inverter device.

[0024] An embodiment of the present application provides an energy storage device. The energy storage device includes a battery pack and an inverter device as described in any of the above embodiments.

[0025] In the above embodiments, the inverter device is provided with a supporting member to facilitate the user to lift it, thereby facilitating the handling and assembly of the energy storage device. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art belonging to the field of the present application. The terms used in the specification of the present application herein are only for the purpose of describing specific implementation manners, and are not intended to limit the present application.

[0047] The terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0048] In the related art, some inverter devices are relatively heavy. Usually, clearance treatment is carried out at some positions at the bottom to set a handle position, so as to facilitate the user to lift the inverter device when carrying or installing the inverter device. However, the handle position will occupy the space at the bottom of the inverter device. Due to space limitations, the layout space reserved for the handle position is small, resulting in a small area of the handle position. It is inconvenient for the user to lift the inverter device and it is easy to touch the wiring terminal, resulting in damage to the wiring terminal.

[0049] The embodiments of the present application provide an inverter device and an energy storage device. The inverter device includes a main unit. The main unit is provided with a wiring terminal. The inverter device further includes a supporting member and a handle. The supporting member is detachably connected to the main unit. The supporting member has a connected fixing part and a supported part. The fixing part is detachably connected to the main unit. The supported part covers the wiring terminal. The side of the supported part facing away from the wiring terminal is configured to be lifted by the user. The handle is connected to the main unit and is located on the opposite side of the main unit from the supporting member.

[0050] By providing a detachable supporting part, when the host needs to be transported and installed, the supporting part is connected to the host, and the user can hold the handle on one side of the host with one hand, and hold the supporting part of the supporting part on the opposite side of the handle with the other hand, so that the user can use both hands to exert force on different sides of the host to lift the inverter device as a whole stably. The supporting part does not occupy the space of the host housing, so it will not be limited by the layout space of the host, and can provide users with a larger lifting area, which is convenient for users to adjust the lifting position of the inverter device, and then convenient for users to exert force to lift the inverter device. The supporting part covers the wiring terminals, which can protect the wiring terminals when lifting the inverter device, which is conducive to preventing the user from being blocked or damaged by the wiring terminals when lifting the inverter device.

[0051] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0052] See also Figure 1 and Figure 2 An embodiment of the present application provides an inverter device 100. The inverter device 100 includes a host 10. The host 10 is provided with a wiring terminal 11. The host 10 is connected to an external device (not shown) through the wiring terminal 11. And the host 10 can realize AC / DC conversion control of the output current or input current of the external device.

[0053] In the related art, the host 10 of the inverter device 100 needs to be fixedly installed at a certain location, such as a building wall, a truck compartment, a motorhome compartment, etc., and the host 10 is heavy, which is not convenient for carrying or maintaining the stability of the host 10 during assembly.

[0054] See also Figure 1 and Figure 2 In some embodiments, the inverter device 100 further includes a supporting member 20 and a handle 30. The supporting member 20 is detachably connected to the host 10. The supporting member 20 has a fixed portion 21 and a trusted portion 22 connected thereto. The fixed portion 21 is detachably connected to the host 10. The trusted portion 22 covers the wiring terminal 11. The side of the trusted portion 22 facing away from the wiring terminal 11 is configured for a user to hold. The handle 30 is connected to the host 10 and is located on the opposite side of the host 10 from the supporting member 20.

[0055] By providing a detachable support member 20, when it is necessary to carry and install the main unit 10, the support member 20 is connected to the main unit 10. The user can grasp the handle 30 on one side of the main unit 10 with one hand and lift the supported portion 22 of the support member 20 on the side opposite to the handle 30 with the other hand, which facilitates the user to apply force on different sides of the main unit 10 with both hands to steadily lift the entire inverter device 100. The supported portion 22 does not occupy the housing space of the main unit 10, so it is not limited by the layout space of the main unit 10, and can provide a relatively large lifting area for the user, facilitating the user to adjust the lifting position of the inverter device 100, and further facilitating the user to apply force to lift the inverter device 100. Moreover, the supported portion 22 covers the wiring terminal 11, which can protect the wiring terminal 11 when lifting the inverter device 100, and is beneficial to avoiding the obstruction of the wiring terminal 11 to the user when lifting the inverter device 100 or damaging the wiring terminal 11.

[0056] In some embodiments, the user is a human. In other embodiments, the user can also be a device such as a robotic arm.

[0057] See Figure 1 , in some embodiments, when it is necessary to carry the inverter device 100 or fixedly assemble the inverter device 100 at a certain position, the support member 20 is connected to the main unit 10, which facilitates the user to lift the inverter device 100 through the support member 20. After the inverter device 100 is fixedly assembled at a certain position, the support member 20 can be detached from the main unit 10 to facilitate the connection of the plug-in terminal to an external device. In this application, the inverter device 100 will be described hereinafter in the state where the support member 20 is connected to the main unit 10.

[0058] See Figure 1 and Figure 2 , in some embodiments, the main unit 10 is provided with a bottom wall 12 and a side wall 13. The bottom wall 12 is provided with a wiring terminal 11. The side wall 13 is adjacent to the bottom wall 12. The side wall 13 is provided with a handle 30.

[0059] The support member 20 and the handle 30 are arranged on two adjacent sides of the main unit 10. Then, when the user lifts the inverter device 100 through the support member 20 and the handle 30, it is convenient to control the posture of the inverter device 100 from two intersecting directions, thus facilitating the maintenance of the stability of the user when lifting the inverter device 100.

[0060] It should be noted that the "bottom" and "side" in the bottom wall 12 and the side wall 13 in this embodiment indicate the relative directions in the posture that is convenient for the inverter device 100 to be carried. For example, the bottom wall 12 can refer to the side of the inverter device 100 close to the ground, and the side wall 13 can refer to the side of the inverter device 100 connected to the bottom wall 12.

[0061] See Figure 1 and Figure 2, in some embodiments, there are two side walls 13 which are arranged opposite to each other. Each side wall 13 is adjacent to the bottom wall 12. Each side wall 13 is provided with a handle 30.

[0062] Handles 30 are provided on the side walls 13 on the opposite sides of the main body 10, facilitating multiple users to lift the inverter device 100 simultaneously, so as to better control the posture of the inverter device 100, which is beneficial to more stably lift the inverter device 100.

[0063] See Figure 1 and Figure 2 , in some embodiments, the main body 10 of the inverter device 100 has a relatively large weight. For example, in some fields with large power consumption demands, a high-power main body 10 is adopted. The high-power main body 10 is heavier than a general low-power main body. At this time, one user is not sufficient to move the main body 10, and at least two people need to work together to carry it. When two people carry the main body 10 together, the two users can be respectively located on one side of the two side walls 13. Each user holds the handle 30 with one hand and holds the supporting part 22 of the bottom wall 12 with the other hand. In this embodiment, the supporting part 22 located on the bottom wall 12 has enough space to accommodate the hands of two users, facilitating the users to adjust their positions to apply force, so as to stably lift the entire inverter device 100. As an exemplary example, high power means greater than 15 kW, and low power means less than 15 kW. It can be understood that the high-power main body 10 is usually heavier than the low-power main body, but it is not limited that the main body 10 is only a high-power main body 10. In other embodiments, the power of the main body 10 can also be lower, and the weight of the main body 10 can also be lighter.

[0064] See Figure 1 and Figure 2 , in some embodiments, after the main body 10 of the inverter device 100 is fixedly assembled to a certain position, the bottom wall 12 is located on the bottom side of the main body 10 along the direction of gravity, and the side walls 13 are located on one side of the main body 10 along the horizontal direction. In some embodiments, the main body 10 is provided with a top wall 14 and a rear wall 15. The top wall 14 is opposite to the bottom wall 12. The side walls 13 and the rear wall 15 are both arranged between the top wall 14 and the bottom wall 12. The rear wall 15 is adjacent to the side walls 13. After the main body 10 of the inverter device 100 is fixedly assembled to a certain position, the top wall 14 is located on the top side of the main body 10 along the direction of gravity, and the rear wall 15 is located on one side of the main body 10 along the horizontal direction.

[0065] See Figure 1 and Figure 2 , it can be understood that, in some embodiments, the rear wall 15 of the main body 10 is configured to be used for the main body 10 to be mutually assembled with an external structure. In other embodiments, the top wall 14 of the main body 10 is configured to be used for the main body 10 to be mutually assembled with an external structure.

[0066] In other embodiments, structures such as terminals or ports for connecting to external devices may be provided at positions such as the side wall 13, top wall 14, and rear wall 15 of the host 10.

[0067] See Figure 2 , in some embodiments, a flat surface, or a curved surface, or a contoured surface adapted to the human palm, or a contoured surface adapted to a robotic hand, or a combination of various differently shaped surfaces is provided on the side of the receiving portion 22 facing away from the connection terminal 11.

[0068] See Figure 2 and Figure 3 , in some embodiments, the receiving portion 22 is provided with an avoidance sub-portion 221 and a support sub-portion 222. The avoidance sub-portion 221 is recessed on the side of the receiving portion 22 facing the connection terminal 11. The avoidance sub-portion 221 covers the area where the connection terminal 11 is located. The support sub-portion 222 is located within the avoidance sub-portion 221. And extending from the side of the receiving portion 22 facing away from the connection terminal 11 to the side facing the connection terminal 11, the support sub-portion 222 abuts against the host 10. Wherein, the support sub-portion 222 being located within the avoidance sub-portion 221 means that at least a part of the projection of the support sub-portion 222 is within the projection range of the avoidance sub-portion 221 in the direction of the receiving portion 22 facing the connection terminal 11.

[0069] By providing the avoidance sub-portion 221, the receiving portion 22 avoids the position of the connection terminal 11 when covering the connection terminal 11, which is beneficial to avoiding the connection terminal 11 being damaged by extrusion of the supporting member 20. At the same time, the receiving portion 22 is provided with a support sub-portion 222 within the range of the avoidance sub-portion 221. When the user lifts the inverter device 100, the support sub-portion 222 can support between the user and the host 10, providing a larger lifting area for the user while maintaining the configuration of the avoidance sub-portion 221, which is beneficial to avoiding the avoidance sub-portion 221 being deformed and squeezing and damaging the connection terminal 11.

[0070] In other embodiments, the avoidance sub-portion can also be used to avoid the positions of other structures of the host 10 except the connection terminal 11.

[0071] See Figure 3 , it can be understood that in some embodiments, multiple avoidance sub-portions 221 can be provided. Multiple support sub-portions 222 can be provided.

[0072] See Figure 3 , it can be understood that in some embodiments, the avoidance sub-portion 221 is a groove-shaped structure. The support sub-portion 222 is a block-shaped structure or a column-shaped structure or a plate-shaped structure.

[0073] See Figure 2 and Figure 3, in some embodiments, the fixing portion 21 includes a first connection hole 211. The host 10 is provided with a second connection hole 16. The inverter device 100 further includes a fastener 40. The fastener 40 passes through the first connection hole 211 and the second connection hole 16 to connect the carrier 20 and the host 10.

[0074] The fastener 40 is simultaneously connected to the carrier 20 and the host 10, so that the carrier 20 is fixed relative to the host 10, which is beneficial to improving the stability when the user lifts the inverter device 100.

[0075] As an exemplary example, the fastener 40 is a screw or a bolt, the first connection hole 211 is a threaded hole or a through hole with a smooth inner wall, and the second connection hole 16 is a threaded hole.

[0076] See Figures 1 to 3 , in some embodiments, when the carrier 20 is connected to the host 10, the fastener 40 passes through the first connection hole 211 and the second connection hole 16 at the same time. When the carrier 20 is detached from the host 10, the fastener 40 can be substantially hidden inside the host 10 through the second connection hole 16. Wherein, the fastener 40 being substantially hidden inside the host 10 means that most of the structure of the fastener 40 can be hidden inside the host 10; for example, when the fastener 40 is a bolt, at least the rod portion structure of the bolt can be hidden inside the host 10.

[0077] See Figures 1 to 3 , in some embodiments, the fixing portion 21 further includes two sets of clamping sub - portions 212. The two sets of clamping sub - portions 212 protrude from the receiving portion 22 toward the side of the wiring terminal 11. The two sets of clamping sub - portions 212 are oppositely arranged and clamp the host 10.

[0078] By providing two sets of clamping sub - portions 212 to clamp the host 10, on the one hand, it is convenient to correct the relative positions of the carrier 20 and the host 10 before the fastener 40 passes through the first connection hole 211 and the second connection hole 16, so as to improve the assembly efficiency between the carrier 20 and the host 10; on the other hand, it can improve the connection stability between the carrier 20 and the host 10 on the basis of the fastener 40 connecting the carrier 20 and the host 10.

[0079] See Figure 3 , it can be understood that, in some embodiments, the clamping sub - portion 212 is a block - shaped structure or a column - shaped structure or a plate - shaped structure.

[0080] See Figure 2 and Figure 3, in some embodiments, the receiving part 22 has a first wall 223 and a second wall 224 facing the side of the terminal block 11. There are two first walls 223 which are arranged opposite to each other at intervals. There are two second walls 224 which are arranged opposite to each other at intervals. Each second wall 224 is connected between the two first walls 223. There are two groups of first connection holes 211. Each group of first connection holes 211 is located on one first wall 223. Each group of clamping sub-parts 212 is located on one second wall 224.

[0081] The two groups of first connection holes 211 and the two groups of clamping sub-parts 212 are arranged around the receiving part 22 facing the side of the terminal block 11, so that the fixing part 21 connects the receiving part 22 and the host 10 in multiple directions, thereby improving the assembly stability between the supporting member 20 and the host 10, facilitating the user to lift the inverter device 100.

[0082] See Figure 3 , it can be understood that in some embodiments, the two groups of first connection holes 211 and the two groups of clamping sub-parts 212 are arranged around the clearance avoidance sub-part 221 and the support sub-part 222.

[0083] See Figure 3 , in some embodiments, each group of first connection holes 211 includes one or more hole positions. Each group of clamping sub-parts 212 includes one or more clamping structures.

[0084] In other embodiments, the fixing part 21 and the host 10 can be connected by a snap-fit structure or a magnetic attraction fit structure.

[0085] See Figure 2 and Figure 3 , in some embodiments, the receiving part 22 and the fixing part 21 are an integrally formed structure to improve the overall structural strength of the supporting member 20.

[0086] See Figure 2 and Figure 3 , in some embodiments, the supporting member 20 is an elastic member. The supporting member 20 can produce elastic deformation when subjected to a force, thereby absorbing the applied force. On the one hand, it can provide buffering for the host 10 to protect the host 10, especially the plug-in terminals; on the other hand, it can provide buffering for the user to improve the feel when the user lifts the inverter device 100.

[0087] In some embodiments, the material of the supporting member 20 is EPP (expanded polypropylene). While being able to produce elastic deformation, it is light in texture, which is beneficial to reducing the overall weight of the inverter device 100. In other embodiments, the material of the supporting member 20 is other plastic or rubber materials, which can basically maintain its own structure to avoid squeezing the plug-in terminals when the user lifts the inverter device 100, and can provide buffering or be light in texture.

[0088] SeeFigure 1 , Figure 4 and Figure 5 , in some embodiments, the handle 30 includes a connecting base 31 and a handle 32. The connecting base 31 is connected to the host 10. The handle 32 is rotatably connected to the connecting base 31. The handle 32 can rotate between a storage position and a working position. When the handle 32 rotates to the storage position, it is closer to the host 10 than when it rotates to the working position. For example, Figure 1 and Figure 2 the handle 32 is in the working position in

[0089] The handle 32 is connected to the host 10 through the connecting base 31, and the inverter device 100 is carried by holding the handle 32. And the handle 32 can be rotated and switched between the storage position and the working position. When the handle 32 is needed, the handle 32 can be in the working position, so that the handle 32 is away from the host 10, thereby providing enough space beside the handle 32 for the user to hold the handle 32; when the handle 32 is not needed, the handle 32 can be in the storage position to reduce the space occupied by the handle 30 beside the host 10, which is beneficial to reducing the overall occupied space of the inverter device 100.

[0090] As an exemplary example, the connecting base 31 is connected to the host 10 by a snap-fit form, or by components such as bolts, or there is a threaded fit connection between the connecting base 31 itself and the host 10.

[0091] See Figure 1 , Figure 4 and Figure 5 , in some embodiments, the connecting base 31 is provided with a limiting portion 311. When the handle 32 rotates from the storage position to the working position, the limiting portion 311 stops the handle 32 from further rotating.

[0092] By providing the limiting portion 311, the position of the handle 32 relative to the host 10 when the handle 32 rotates to the working position is restricted, so that the handle 32 is fixed relative to the host 10 when the user holds the handle 32 to carry the inverter device 100, thereby improving the stability of the inverter device 100 when the user carries the inverter device 100.

[0093] It can be understood that, in some embodiments, the limiting portion 311 is a groove-shaped structure. When the handle 32 rotates into the groove-shaped structure of the limiting portion 311, the groove wall stops the handle 32 to limit the handle 32.

[0094] See Figure 1 , Figure 4 and Figure 5 , in some embodiments, the handle 32 is provided with a first heat dissipation port 321. The host 10 is provided with a second heat dissipation port 17. When the handle 32 rotates to the storage position, at least part of the first heat dissipation port 321 is opposite to at least part of the second heat dissipation port 17.

[0095] The handle 32 is provided with a first heat dissipation port 321 to reduce the occlusion of the second heat dissipation port 17. While reducing the overall occupied space of the inverter device 100, it is beneficial to reduce the impact on the heat dissipation efficiency of the host 10 exhausting air outward through the second heat dissipation port 17.

[0096] See Figure 4 and Figure 5 , it can be understood that in some embodiments, the first heat dissipation port 321 is a hollowed-out area provided on the handle 32. In other embodiments, the first heat dissipation port 321 can also be multiple hollowed-out areas provided on the handle 32.

[0097] See Figure 1 and Figure 2 , in some embodiments, the position of the handle 30 in each side wall 13 is configured such that when the posture of the inverter device 100 is such that the insertion terminal is located at the bottom of the host 10 along the direction of gravity, the position of the handle 30 is higher than the center of gravity of the host 10, so that when the user holds the handle 30 to control the posture of the host 10, the posture of the host 10 can be adjusted.

[0098] See Figure 6 and Figure 7 , an embodiment of the present application provides an energy storage device 200. The energy storage device 200 has the functions of storing and discharging electricity, and is used for home power backup, power backup for production units, outdoor operations, outdoor entertainment, etc. The energy storage device 200 includes a battery pack 201 and the inverter device 100 in any of the above embodiments. The energy storage device 200 can be a small portable mobile power supply, a household energy storage power supply, an industrial and commercial energy storage power supply, or a containerized energy storage power supply, etc. The inverter device 100 is carried by the carrier 20 to facilitate the user to lift, so as to facilitate the handling and assembly of the energy storage device 200.

[0099] See Figure 6 and Figure 7 , in some embodiments, the energy storage device 200 further includes a cable 202. The battery pack 201 and the inverter device 100 are electrically connected through the cable 202.

[0100] See Figure 6 , the battery pack 201 and the inverter device 100 are relatively independently arranged. The user can separately carry or assemble the battery pack 201 and the inverter device 100. See Figure 7 , in some embodiments, the energy storage device 200 further includes a housing 203. The battery pack 201 and the inverter device 100 are both arranged inside the housing 203, so that the battery pack 201 and the inverter device 100 form an integral body, which is convenient for protecting the battery pack 201 and the inverter device 100.

[0101] In addition, those of ordinary skill in the art should recognize that the above embodiments are merely used to illustrate the present application and are not intended to limit the present application. As long as appropriate changes and variations made to the above embodiments fall within the scope of the spirit of the present application, they are within the scope of the disclosure of the present application.
