Description

Technical Field

[0001] This application relates to the field of new energy technology, and in particular to an inverter and a photovoltaic-storage integrated machine. Background Technology

[0002] With the rapid development of new energy sources, inverters such as photovoltaic inverters and wind power inverters can communicate with terminals via wireless signals.

[0003] For example, inverters can be configured with wireless communication modules and external antennas. The inverter communicates with communication terminals such as routers or mobile phones via these modules and antennas. This allows for tasks such as on-site configuration and reading of operational data. However, in related technologies, antenna communication for inverters has poor reliability, and the inverters are not easily stored.

[0004] Therefore, there is an urgent need for an inverter with high communication reliability and easy storage. Summary of the Invention

[0005] This application provides an inverter and a photovoltaic-storage integrated machine. The inverter has high communication reliability and is easy to store.

[0006] In a first aspect, embodiments of this application provide an inverter, including a housing, a circuit board, a connector, and an antenna. The housing includes a first mounting wall and has a receiving cavity within it. The circuit board is located within the receiving cavity. The connector passes through and is connected to the first mounting wall of the housing. The antenna is electrically connected to the circuit board via the connector, and the antenna is rotatable relative to the housing about the connection point between the antenna and the connector.

[0007] The inverter provided in this application embodiment comprises a housing, a circuit board, a connector, and an antenna. The housing includes a first mounting wall and has a receiving cavity. The circuit board is located within the receiving cavity. The connector passes through and connects to the first mounting wall of the housing. The antenna is electrically connected to the first circuit board via the connector. The antenna can rotate relative to the housing around the connection point between the antenna and the connector, which effectively enhances the wireless communication signal strength between the antenna and the mobile terminal, reduces signal obstruction and transmission loss, and improves signal reliability and receiving sensitivity, resulting in high communication reliability between the inverter and the mobile terminal. The ability of the antenna to rotate relative to the housing around the connection point between the antenna and the connector also allows for a smaller angle between the antenna and the side wall where the antenna is located, resulting in a smaller overall shape of the inverter and facilitating its storage during transportation.

[0008] In one possible implementation, the inverter provided in this application includes a first connector and a second connector. The first connector passes through a first mounting wall of the housing and is sealed to the first mounting wall, and is electrically connected to a circuit board. The second connector is connected to the portion of the first connector that extends outside the housing, and the antenna is rotatable relative to the second connector. The sealed connection between the first connector and the first mounting wall reduces the possibility of moisture, dust, etc., entering the cavity from the connection between the connector and the housing, thus improving the housing protection reliability of the inverter. The portion of the antenna that rotates relative to the connector is located outside the cavity, and the frictional losses from rotation do not affect the seal between the connector and the first mounting wall, further enhancing the housing protection reliability of the inverter while maintaining high communication reliability.

[0009] In one possible implementation, the inverter provided in this application includes a connector that further comprises a connecting member. One end of the connecting member is connected to a second connector, and the antenna is rotatably connected to the other end of the connecting member. By providing the adapter, damage to the second connector during antenna rotation can be reduced, and the impact on the connection reliability of the first and second connectors can be minimized.

[0010] In one possible implementation, the inverter provided in this application further includes a limiting member. When the limiting member is in a first position, a portion of the limiting member is connected to the antenna and a portion of the limiting member is connected to a connector, and the antenna remains stationary relative to the connector. When the limiting member is in a second position, the limiting member is connected to the antenna, and the antenna can rotate around the connection point between the antenna and the connector. This allows for flexible antenna rotation to adjust to the optimal signal position, while also preventing accidental antenna deflection or angular shift caused by outdoor wind or equipment vibration, thus stabilizing the antenna attitude and further improving communication reliability.

[0011] In one possible implementation, the inverter provided in this application uses a ring-shaped limiting member. When the limiting member is in a first position, a portion of the limiting member is fitted onto the antenna and a portion onto the connector. The portion of the limiting member fitted onto the antenna engages with the outer wall of the antenna, and the portion of the limiting member fitted onto the connector engages with the outer wall of the connector. When the limiting member is in a second position, it is fitted onto the outer wall of the antenna, allowing the antenna to rotate circumferentially around the connector. In the first position, the ring-shaped limiting member not only restricts the rotation of the antenna relative to the connector but also increases the strength of the connection between the antenna and the connector, resulting in higher communication and structural reliability of the inverter.

[0012] In one possible implementation, the inverter provided in this application includes a connector comprising a connecting portion and a limiting portion. The connecting portion is connected to the limiting portion, and the limiting portion is connected to a second connector. When the limiting portion is in a first position, a portion of the limiting portion is fitted onto the limiting portion. An antenna is fitted onto the outer wall of the connecting portion, and the antenna can rotate circumferentially around the connecting portion. The partial overlap between the antenna and the connector shortens the length of the protruding housing at the connection between the connector and the antenna, improving overall structural reliability and increasing the compactness of the inverter. The connection between the antenna and the connector forms a three-layer structure from the inside out, including the connecting portion, the antenna, and the limiting portion, further increasing the structural strength of the connection between the antenna and the connector.

[0013] In one possible implementation, the inverter provided in this application embodiment has a first rack arranged at intervals along its outer periphery on the outer wall of the limiting part, and a second rack that can mesh with the first rack on the inner wall of the limiting member. The rack meshing is a surface contact rigid limiting, with a small meshing gap and uniform locking force, which can effectively counteract the torsional force generated by outdoor wind and equipment vibration, making it less prone to loosening and slippage, and providing good posture stability over long-term use.

[0014] In one possible implementation, the inverter provided in this application has an antenna with protrusions spaced along its outer periphery on its outer wall, and a limiting member with multiple grooves on its inner wall, into which the protrusions are respectively inserted. The protrusions and grooves can guide the movement of the limiting member, so that the movement path of the limiting member is the arrangement direction of the antenna and the connector, thus preventing the first rack and the second rack from misaligning when the limiting member moves back to the first position, which would affect the meshing of the first rack and the second rack.

[0015] In one possible implementation, the inverter provided in this application embodiment has a first limiting platform on the outer wall of the limiting part and a second limiting platform on the outer wall of the antenna. The first and second limiting platforms can constrain the limiting member to a first position. This prevents accidental contact that could cause the limiting member to move and release the angle restriction on the antenna, and allows the limiting member to reliably limit the rotation of the antenna.

[0016] In one possible implementation, the inverter provided in this application embodiment has a damping ring fitted on the outer wall of the connection portion, with the damping ring abutting between the outer wall of the connection portion and the inner wall of the antenna. This allows for a higher degree of maneuverability during antenna rotation.

[0017] In one possible implementation, the inverter provided in this application includes a first connector comprising a connector body, a first mounting plate, and a second mounting plate. Both the first and second mounting plates are sleeved on the outer periphery of the connector body. The first mounting plate is located on the side of the first mounting wall facing the outside of the housing, and the second mounting plate is located on the side of the first mounting wall facing the receiving cavity. The first and second mounting plates are sealed to the respective first mounting walls. This ensures a reliable connection between the first connector and the first mounting wall, preventing the first connector from shifting within the opening. The double sealing by the first and second seals provides high protection reliability for the inverter.

[0018] In one possible implementation, the inverter provided in this application embodiment has a protective flange on the side of the first mounting wall facing the outside of the housing, and the protective flange surrounds the outside of the first mounting plate. The protective flange can prevent rainwater, sand, etc. from directly impacting the connection between the first mounting plate and the first mounting wall, thereby further improving the sealing effect.

[0019] In one possible implementation, the inverter provided in this application includes an antenna body and a bend connector, one end of which is connected to the antenna body and the other end of which is rotatably connected to a connector.

[0020] In one possible implementation, the inverter provided in this application has its antenna extending beyond the outer periphery of the housing when in the operating state. When the antenna is in the retracted state, it is located within the outer periphery of the housing. This allows for a smaller size of the inverter along either the first or second direction, facilitating its placement in a packaging box during transport.

[0021] In one possible implementation, the inverter provided in this application has a housing including a first sidewall, a first mounting wall connected to the first sidewall and bent from the first sidewall toward the interior of the receiving cavity to form a receiving groove in a region near the first mounting wall. When the antenna is in a retracted state, the antenna can rotate relative to the housing to be located within the receiving groove. That is, setting up the antenna does not increase the size of the housing in a third direction, making the inverter structure more compact.

[0022] In one possible implementation, the inverter provided in this application further includes a second sidewall in its housing, which is disposed opposite to the first sidewall and has a first terminal. Therefore, the first terminal will not interfere with the rotation of the antenna or cause interference to the antenna signal.

[0023] In one possible implementation, the inverter provided in this application further includes a third sidewall in its housing. This third sidewall connects between the first and second sidewalls, and its surface intersects with the surfaces of both the first and second sidewalls. The third sidewall is provided with a second terminal and a third terminal, and the antenna is located on the side of the first sidewall facing away from the third sidewall. Therefore, the second and third terminals do not interfere with the rotation of the antenna and do not interfere with the antenna signal.

[0024] Secondly, embodiments of this application provide a photovoltaic-storage integrated machine, including a battery pack and the aforementioned inverter. The inverter and the battery pack are stacked together. The inverter includes a housing and an antenna. The housing includes a first sidewall and a second sidewall facing each other. The second sidewall faces the battery pack. The antenna is disposed on the first sidewall and is rotatable relative to the housing.

[0025] It should be understood that the second aspect of this application corresponds to the technical solution of the first aspect of this application, and the beneficial effects achieved by each aspect and the corresponding feasible implementation are similar, and will not be repeated here.

[0081] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0082] With the rapid development of new energy sources, photovoltaic power generation is becoming increasingly widespread. However, photovoltaic power generation is greatly affected by weather and sunlight, resulting in unstable power generation and an inability to provide a continuous and stable power supply. Integrated photovoltaic-energy storage systems combine inverter, energy storage, and photovoltaic control functions into one unit. With a simple structure and easy installation, they can realize functions such as self-consumption of photovoltaic power generation, storage of excess energy, and emergency power supply during power outages. They are widely applicable to various scenarios including household electricity, industrial and commercial electricity, power supply in remote areas, field equipment, and base station energy storage, effectively improving energy utilization and ensuring stable power supply.

[0083] Figure 1 This is a schematic diagram of the structure of the integrated photovoltaic and energy storage machine provided in the embodiments of this application. Figure 2 This is a diagram showing the usage status of the integrated photovoltaic and energy storage unit provided in the embodiments of this application.

[0084] See Figure 1 and Figure 2 As shown, the integrated photovoltaic and energy storage system 1000 includes an inverter 10 and a battery pack 20. The inverter 10 can be stacked on one side of the battery pack 20. The inverter 10 includes a first terminal 10a, through which it is electrically connected to the battery pack 20. The inverter 10 also includes a second terminal 10b and a third terminal 10c, which can be located on a side other than the side of the inverter 10 facing the battery pack 20. The first terminal 10a and the third terminal 10c are AC terminals, and the second terminal 10b is a DC terminal. The second terminal 10b is used for electrical connection to the photovoltaic module 2000, and the third terminal 10c is used for electrical connection to the grid 3000 or the user 4000.

[0085] See Figure 2 As shown, the photovoltaic module 2000 converts solar energy into direct current through the photovoltaic effect. The direct current is transmitted to the inverter 10 through the second terminal 10b. The inverter 10 can convert the direct current into alternating current and then transmit it to the grid 3000 or the user 4000 through the third terminal 10c.

[0086] When the power generated by the photovoltaic module 2000 is insufficient, the DC power from the battery pack 20 is transmitted to the inverter 10 through the first terminal 10a. The inverter 10 converts the DC power into AC power and then transmits it to the grid 3000 or the user 4000 through the third terminal 10c. The AC power from the grid 3000 can also be transmitted to the inverter 10 through the third terminal 10c. The inverter 10 converts the AC power into DC power and then transmits it to the battery pack 20 for storage through the DC terminal.

[0087] As can be seen, the inverter in the photovoltaic-storage integrated machine 1000 is a bidirectional inverter 10. The bidirectional inverter 10 means that it can convert the DC power from the photovoltaic modules 2000 and battery pack 20 into AC power, and also convert the DC power from the grid 3000 or the user's 4000 home power into DC power. The inverter 10 may include an antenna 100, which can connect to a mobile terminal. This allows for real-time data viewing, operational status monitoring, remote adjustment of operating modes, and parameter debugging of the inverter 10, ensuring its stable operation.

Figure 6 This is a partial structural diagram of the antenna and housing in an inverter provided in an embodiment of this application. Figure 7 for Figure 6 A partial structural diagram. Figure 8 for Figure 7 An explosion diagram. Figure 9 for Figure 7 A cross-sectional schematic diagram.

[0089] See Figures 3 to 9 As shown, the inverter 10 provided in this embodiment includes a housing 200, a circuit board 300, a connector 400, and an antenna 100. The housing 200 includes a first mounting wall 210 and has a receiving cavity inside. The circuit board 300 is located within the receiving cavity. The connector 400 passes through and is connected to the first mounting wall 210 of the housing 200. The antenna 100 is electrically connected to the circuit board 300 via the connector 400, and the antenna 100 is rotatable relative to the housing 200 around the connection point between the antenna 100 and the connector 400.

[0090] Please continue reading Figures 3 to 5As shown, the outer contour of the housing 200 can be a cuboid structure. The width, length, and thickness directions of the housing 200 are shown in the figure along the first direction X, the second direction Y, and the third direction Z. The housing 200 includes a bottom shell 220 and a top cover 230. The bottom shell 220 includes a bottom plate 221 and four side walls 222 surrounding the bottom plate 221. The first side wall 2221 and the second side wall 2222 are spaced apart along the first direction X, and the third side wall 2223 and the fourth side wall 2224 are spaced apart along the second direction Y. The top cover 230 covers the bottom shell 220, and the top cover 230 and the bottom shell 220 form a receiving cavity. A partial area of ​​one side wall 222 in the housing 200 where the antenna 100 is mounted is a first mounting wall 210. In this embodiment, the first mounting wall 210 is located on one side of the first side wall 2221.

[0091] The circuit board 300 can be disposed in the receiving cavity and connected to the bottom shell 220 or the top cover 230 of the housing 200. The connector 400 can be mounted on the first mounting wall 210, that is, one end of the connector 400 is located inside the receiving cavity, and the other end extends out of the receiving cavity. The antenna 100 can be electrically connected to the connector 400 and connected to the circuit board 300 through the connector 400.

[0092] The circuit board 300 may include a first circuit board 310 and a second circuit board 320, both of which are housed within a receiving cavity. A first terminal 10a, a second terminal 10b, and a third terminal 10c are all electrically connected to the first circuit board 310. The second circuit board 320 is electrically connected to the first circuit board 310 and is used to mount communication circuitry. The antenna 100 can be electrically connected to the communication circuitry on the second circuit board 320 via a first cable 500.

[0093] Specifically, the first circuit board 310 is disposed opposite to the base plate 221, and the surface of the second circuit board 320 can be disposed perpendicular to the surface of the first circuit board 310, intersect with the surface of the first circuit board 310, or be parallel to the surface of the first circuit board 310. Figure 5 In this configuration, the surface of the second circuit board 320 is perpendicular to the surface of the first circuit board 310. The first circuit board 310 is the main circuit board 300 in the inverter 10, used to connect the power devices (such as capacitors, inductors, etc.) in the photovoltaic inverter 10, the first terminal 10a, the second terminal 10b, the third terminal 10c, and the second circuit board 320. The distance between the second circuit board 320 and the first circuit board 310 in the high-voltage environment is relatively large, making the vicinity of the second circuit board 320 a low-voltage environment.

[0094] Furthermore, the cavity can be divided into multiple independent sub-cavities. The arrangement of these sub-cavities isolates the components, reducing electromagnetic interference between them. Specifically, the second circuit board 320 can be located in a separate sub-cavity. The plane of the second circuit board 320 containing the communication circuit is perpendicular to the plane of the first circuit board 310 containing the power devices. The area near the first circuit board 310 is a high-voltage environment, while the sub-cavity containing the second circuit board 320 is a low-voltage environment. Placing the communication circuit on the second circuit board 320 improves operational safety during live maintenance of the inverter 10. Moreover, placing the communication circuit on the second circuit board 320 instead of the first circuit board 310 reduces electromagnetic interference from the power devices on the first circuit board 310, ensuring the communication quality and reliability of the antenna 100.

[0095] The second circuit board 320 is connected to a first cable 500, which is connected to the end of the connector 400 facing the receiving cavity. Thus, the antenna 100 and the second circuit board 320 can be connected through the connector 400.

[0096] Antenna 100 can be a WiFi antenna, a 4G / 5G antenna, or a Bluetooth antenna. Antenna 100 enables signal transmission and reception, and the communication circuit on the second circuit board 320 enables signal control. For example, when transmitting a signal, the communication circuit can modulate and amplify the signal before transmitting it through antenna 100. When receiving a signal, antenna 100 captures the signal in space and converts it into high-frequency current energy. The communication circuit amplifies and filters the signal, then converts it into a digital signal for processing by other devices on the second circuit board 320.

[0097] Please continue reading Figure 6 yes Figure 9 As shown, antenna 100 can rotate relative to housing 200 about the connection point between antenna 100 and connector 400 (in Figure 3 and Figure 4 The diagram shows three different angles of antenna 100. By rotating antenna 100, the signal transmission and reception angles can be freely adjusted, ensuring that antenna 100 is positioned at the angle with the strongest signal. This effectively enhances the wireless communication signal strength between antenna 100 and the mobile terminal, reduces signal obstruction and transmission loss, and improves signal reliability and reception sensitivity. A stable communication signal allows the second circuit board 320 to quickly and accurately complete equipment data acquisition, operating status feedback, remote parameter reception, and command execution. This enables real-time viewing of inverter 10 data, monitoring of operating status, remote adjustment of operating modes, and parameter debugging. In other words, the communication reliability between inverter 10 and the mobile terminal is high.

[0098] The antenna 100 can rotate relative to the housing 200 around the connection point between the antenna 100 and the connector 400. It can also make the included angle between the antenna 100 and the side wall 222 where the antenna 100 is located smaller. For example, when transporting the inverter 10, the antenna 100 can be rotated to make the included angle with the first side wall 2221 smaller or parallel to the first side wall 2221. As a result, the overall outline of the inverter 10 can be made smaller, making it easier to store the inverter 10 in the packaging box when transporting the inverter 10.

[0099] The inverter 10 provided in this embodiment comprises a housing 200, a circuit board 300, a connector 400, and an antenna 100. The housing 200 includes a first mounting wall 210 and has a receiving cavity. The circuit board 300 is located within the receiving cavity. The connector 400 passes through and is connected to the first mounting wall 210 of the housing 200. The antenna 100 is electrically connected to the first circuit board 310 via the connector 400. The antenna 100 can rotate relative to the housing 200 around the connection point between the antenna 100 and the connector 400, which can effectively enhance the wireless communication signal strength between the antenna 100 and the mobile terminal, reduce signal obstruction and transmission loss, improve signal reliability and receiving sensitivity, and thus ensure high communication reliability between the inverter 10 and the mobile terminal. The antenna 100 can rotate relative to the housing 200 around the connection point between the antenna 100 and the connector 400. It also allows the included angle between the antenna 100 and the side wall 222 where the antenna 100 is located to be smaller, which makes the overall shape of the inverter 10 smaller and facilitates the storage of the inverter 10 during transportation.

[0100] Figure 10 for Figure 7 Another diagram of an explosion.

[0101] See Figure 9 and Figure 10 As shown, in one possible implementation, connector 400 includes a first connector 410 and a second connector 420. The first connector 410 passes through and is sealed to the first mounting wall 210 of housing 200, and is electrically connected to circuit board 300. The second connector 420 is connected to the portion of the first connector 410 that extends outside housing 200, and antenna 100 is rotatable relative to the second connector 420.

[0102] One of the first connector 410 and the second connector 420 is a male connector, and the other is a female connector. Figure 9 and Figure 10In the illustrated embodiment, the first connector 410 is a male connector, and the second connector 420 is a female connector. An opening penetrating the first mounting wall 210 can be formed in the first mounting wall 210, and the first connector 410 is inserted into the opening, such that part of the first connector 410 is located within the receiving cavity and part extends outside the receiving cavity. The first mounting wall 210 has opposing first surfaces 211 and second surfaces 212, with the first surface 211 facing the interior of the receiving cavity and the second surface 212 facing the exterior of the receiving cavity. A seal can be provided between the first connector 410 and the inner wall of the opening, so that the first connector 410 is sealed to the first mounting wall 210. The portion of the first connector 410 located within the receiving cavity is connected via a first cable 500 (… Figure 6 and Figure 7 (As shown in the figure) is electrically connected to the second circuit board 320.

[0103] The outer periphery of the portion of the first connector 410 extending outside the receiving cavity may be provided with external threads. The second connector 420 may have a mounting hole with internal threads on its inner wall. The first connector 410 is inserted into the mounting hole and threadedly connected to the hole wall. The first connector 410 and the second connector 420 are electrically connected. The antenna 100 is rotatable relative to the second connector 420; that is, the portion of the antenna 100 that rotates relative to the connector 400 is located outside the receiving cavity.

[0104] The integrated photovoltaic and energy storage unit 1000 is mostly located outdoors, as is the inverter 10. It is sealed to the first mounting wall 210 via the first connector 410 to reduce the possibility of moisture, dust, etc., entering the housing cavity from the connection between the connector 400 and the housing 200, thus ensuring high protection reliability of the inverter 10's housing 200. The rotating portion of the antenna 100 relative to the connector 400 is located outside the housing cavity. Frictional losses from rotation do not affect the seal between the connector 400 and the first mounting wall 210, further enhancing the protection reliability of the inverter 10's housing 200 while maintaining high communication reliability.

[0105] Please continue reading Figure 9 and Figure 10 As shown, in one possible implementation, connector 400 further includes connector 430, one end of which is connected to second connector 420, and antenna 100 is rotatably connected to the other end of connector 430.

[0106] One end of the connector 430 can be fixedly connected to the second connector 420, and the antenna 100 can be rotatably connected to the other end of the connector 430. The connector 430 is essentially an adapter between the second connector 420 and the antenna 100. That is, the area where the antenna 100 connects to the connector 400 is located on the connector 430. When the antenna 100 rotates relative to the connector 430, it will not directly exert force on the second connector 420. Therefore, by setting the adapter, the damage to the second connector 420 when the antenna 100 rotates can be reduced, and the impact on the connection reliability of the first connector 410 and the second connector 420 can be reduced.

[0107] Inverter 10 is typically installed outdoors, where natural wind, equipment vibration, and environmental disturbances continuously generate unpredictable external forces. These forces cause antenna 100 to deflect, deviating from its preset operating angle, leading to signal attenuation, connection interruption, and other problems. This embodiment addresses this issue by incorporating a limiting member 600.

[0108] Figure 11 This is another partial structural diagram of the antenna and housing in the inverter provided in the embodiments of this application. Figure 12 for Figure 11 Cross-sectional view. Figure 13 for Figure 11 Another schematic diagram of the state. Figure 14 for Figure 13 A cross-sectional view. Among them, Figure 11 and Figure 12 The limiting component is in the first position. Figure 13 and Figure 14 The middle limit component is in the second position.

[0109] See Figures 11 to 14 As shown, the inverter 10 also includes a limiting member 600. When the limiting member 600 is in a first position, a portion of the limiting member 600 is connected to the antenna 100 and a portion of the limiting member 600 is connected to the connector 430, and the antenna 100 remains stationary relative to the connector 430. When the limiting member 600 is in a second position, the limiting member 600 is connected to the antenna 100, and the antenna 100 can rotate around the connection point between the antenna 100 and the connector 430.

[0110] The first position can be the locked position of the antenna 100 relative to the connector 430. When the limiting member 600 is in the first position, it restricts the antenna 100 from rotating relative to the connector 430, keeping the antenna 100 at a fixed angle relative to the housing 200 to resist displacement caused by outdoor wind and vibration. The second position can be the unlocked position of the antenna 100 relative to the connector 430. At this time, the constraint of the limiting member 600 on the antenna 100 is released, and the antenna 100 can rotate around its connection position with the connector 430, facilitating manual adjustment of its orientation and angle.

[0111] Therefore, the antenna 100 can be rotated flexibly to adjust it to the optimal position for signal transmission, and the antenna 100 can be prevented from being deflected or shifted at an angle due to outdoor wind or equipment vibration, thus stabilizing the antenna 100's attitude and further improving communication reliability.

[0112] In one possible implementation, the limiting member 600 can be a bolt. When it is necessary to fix the angle of the antenna 100 relative to the housing 200, the bolt is in a first position. The bolt can be simultaneously inserted into the connector 430 and the antenna 100, and the bolt can restrict the rotation of the antenna 100 relative to the connector 430. When it is necessary to adjust the angle of the antenna 100, the bolt is pulled out from at least one of the connector 430 and the antenna 100, so that the antenna 100 can rotate relative to the connector 430.

[0113] Please continue reading Figures 11 to 14 As shown, in another possible implementation, the limiting member 600 is an annular limiting member. When the limiting member 600 is in the first position, a portion of the limiting member 600 is fitted onto the antenna 100 and a portion is fitted onto the connector 430. The portion of the limiting member 600 fitted onto the antenna 100 engages with the outer wall of the antenna 100, and the portion of the limiting member 600 fitted onto the connector 430 engages with the outer wall of the connector 430. When the limiting member 600 is in the second position, the limiting member 600 is fitted onto the outer wall of the antenna 100, and the antenna 100 can rotate circumferentially around the connector 430.

[0114] The annular limiting member has a hollow internal structure and includes a first limiting segment 610 and a second limiting segment 620 connected to the first limiting segment 610. When the annular limiting member is in the first position, the first limiting segment 610 is fitted onto the antenna 100, and the second limiting segment 620 is fitted onto the connector 430. The first limiting segment 610 engages with the outer wall of the antenna 100, and the second limiting segment 620 engages with the outer wall of the connector 430. The annular limiting member can restrict the antenna 100 from rotating relative to the connector 430.

[0115] When the annular limiting member is moved along its length direction until the first limiting segment 610 and the second limiting segment 620 of the annular limiting member are both fitted onto the outer wall of the antenna 100, the limiting of the antenna 100 relative to the connector 430 is released, and the antenna 100 can rotate relative to the connector 430.

[0116] By setting the limiting member 600 as a ring-shaped limiting member, the ring-shaped limiting member can not only restrict the rotation of the antenna 100 relative to the connector 430 in the first position, but also increase the strength of the connection between the antenna 100 and the connector 430, so that the communication reliability and structural reliability of the inverter 10 are both high.

[0117] In addition, in the second position, the annular limiting member does not need to be removed from the antenna 100, which can prevent the limiting member 600 from being lost, thus making the inverter 10 more reliable in the long term.

[0118] The connector 430 includes a connecting portion 431 and a limiting portion 432. The connecting portion 431 is connected to the limiting portion 432, and the limiting portion 432 is connected to the second connector 420. When the limiting member 600 is in the first position, a portion of the limiting member 600 is fitted onto the limiting portion 432. The antenna 100 is fitted onto the outer wall of the connecting portion 431, and the antenna 100 is rotatable around the circumference of the connecting portion 431.

[0119] The limiting part 432 faces the second connector 420 and is fixedly connected to the second connector 420. The limiting part 432 is the area in the connector 430 that mates with the limiting member 600. The antenna 100 is sleeved on the outer wall of the connecting part 431, and the antenna 100 can rotate around the circumference of the connecting part 431, thereby changing the angle of the antenna 100 relative to the housing 200. By sleeved on the outer wall of the connecting part 431, the antenna 100 overlaps with a portion of the connector 430, which can shorten the length of the connection between the connector 400 and the antenna 100 protruding from the housing 200, avoiding excessive length at the connection point that is prone to bending, improving the overall structural reliability, and increasing the structural compactness of the inverter 10.

[0120] In addition, the antenna 100 is sleeved on the outer wall of the connecting part 431, and the first limiting segment 610 of the limiting member 600 is sleeved on the outer wall of the antenna 100. The connection between the antenna 100 and the connector 400 forms a three-layer structure from the inside to the outside, including the connecting part 431, the antenna 100 and the limiting member 600, which further increases the structural strength of the connection between the antenna 100 and the connector 400.

[0121] The specific structure of the limiting component 600 will be explained below.

[0122] Figure 15 An exploded view of the connectors, limiting members, and antenna in the inverter provided in this application embodiment. Figure 16for Figure 15 Another view.

[0123] See Figure 15 and Figure 16 As shown, in one possible implementation, the outer wall of the limiting portion 432 has a first rack 4321 arranged at intervals along its outer periphery, and the inner wall of the limiting member 600 has a second rack 621 capable of engaging with the first rack 4321.

[0124] The limiting portion 432 has a plurality of first racks 4321 protruding from the outer periphery, and the plurality of first racks 4321 are arranged at intervals along the outer periphery of the limiting portion 432. The interval distance and the length of the first racks 4321 can be determined according to the force required to limit the rotation of the antenna 100.

[0125] The inner wall of the second limiting segment 620 is provided with a plurality of second racks 621 spaced apart along its inner wall. The number of second racks 621 can be the same as the number of first racks 4321. When the limiting member 600 is in the first position, the second racks 621 are inserted between two adjacent first racks 4321, and the first racks 4321 are inserted between two adjacent second racks 621, so that the first racks 4321 and the second racks 621 mesh. The meshing of the first racks 4321 and the second racks 621 can fix the position of the limiting member 600 relative to the connector 430, thereby fixing the angle of the antenna 100 relative to the housing 200.

[0126] The rack and pinion engagement is a surface-contact rigid limiting mechanism with a small meshing gap and uniform locking force. This effectively counteracts the torsional forces generated by outdoor wind and equipment vibration, making it less prone to loosening or slippage and ensuring good posture stability over long-term use. In addition, external forces are shared by multiple racks, resulting in less localized stress and less stress concentration, making it more suitable for complex outdoor working conditions.

[0127] Please continue reading Figure 15 and Figure 16 As shown, in one possible implementation, the outer wall of the antenna 100 has protrusions 110 arranged at intervals along its outer periphery, and the inner wall of the limiting member 600 has a plurality of grooves 611, with the protrusions 110 respectively inserted into the grooves 611.

[0128] The outer wall of the antenna 100 has a plurality of protruding strips 110 extending from its outer periphery, and the plurality of protruding strips 110 are arranged at intervals along the outer periphery of the antenna 100. The inner wall of the first limiting section 610 has a plurality of grooves 611 arranged at intervals along its interior, and the protruding strips 110 are correspondingly inserted into the grooves 611. In the first position, the first rack 4321 of the limiting part 432 and the second rack 621 of the limiting member 600 engage, and the protruding strips 110 of the antenna 100 are inserted into the grooves 611 of the limiting member 600. Thus, the rotation of the antenna 100 relative to the connecting member 430 can be restricted by the limiting member 600.

[0129] When the antenna 100 needs to rotate relative to the connector 430, an external force is applied to the limiting member 600, causing the limiting member 600 to move toward the antenna 100. The first rack 4321 and the second rack 621 disengage, while the protrusion 110 remains inserted in the groove 611. The protrusion 110 and the groove 611 can guide the movement of the limiting member 600, so that the movement path of the limiting member 600 is the arrangement direction of the antenna 100 and the connector 430. This prevents the first rack 4321 and the second rack 621 from misaligning when the limiting member 600 moves back to the first position, thus affecting the engagement of the first rack 4321 and the second rack 621.

[0130] Figure 17 for Figure 12 Enlarged view of point A in the middle.

[0131] See Figures 15 to 17 As shown, the outer wall of the limiting part 432 has a first limiting platform 433, and the outer wall of the antenna 100 has a second limiting platform 120. The first limiting platform 433 and the second limiting platform 120 can constrain the limiting member 600 to a first position.

[0132] The first limiting platform 433 is located on the side of the limiting part 432 away from the connecting part 431, and the outer diameter of the first limiting platform 433 is larger than the outer diameter of the limiting part 432. When the limiting member 600 is in the first position, the end face of the first limiting platform 433 facing the limiting member 600 abuts against the limiting member 600, which can prevent the limiting member 600 from moving past the connecting member 430 toward the second connector 420.

[0133] The outer wall of the antenna 100 has a second limiting platform 120. The outer diameter of the second limiting platform 120 is larger than the outer diameter of other areas of the antenna 100 that cooperate with the limiting member 600. The second limiting platform 120 has a first inclined surface 121 facing the limiting part 432 and a second inclined surface 122 facing away from the limiting part 432.

[0134] The inner wall of the first limiting segment 610 is provided with a third limiting platform 612. The third limiting platform 612 has a third inclined surface 6121 that cooperates with the first inclined surface 121 and a fourth inclined surface 6122 that cooperates with the second inclined surface 122. The first inclined surface 121 and the third inclined surface 6121 abut against each other, which can prevent the limiting member 600 from moving toward the antenna 100. The first limiting platform 433 and the second limiting platform 120 can constrain the limiting member 600 to the first position. Thus, it can prevent accidental contact that would cause the limiting member 600 to move and release the angle restriction on the antenna 100, and can make the limiting member 600 reliably restrict the rotation of the antenna 100.

[0135] When the angle of antenna 100 relative to housing 200 needs to be adjusted, a force is applied to the limiting member 600 to move towards antenna 100. This force must be greater than the frictional force of the first inclined surface 121 and the third inclined surface 6121. The third limiting platform 612 moves past the second limiting platform 120, causing the limiting member 600 to move towards antenna 100. The first rack 4321 disengages from the second rack 621, allowing antenna 100 to rotate relative to connector 430. After the angle of antenna 100 is adjusted, a force is applied to antenna 100 to move towards connector 430. This force must be greater than the frictional force of the second inclined surface 122 and the fourth inclined surface 6122. The third limiting platform 612 moves past the second limiting platform 120 towards connector 430. The first rack 4321 engages with the second rack 621, allowing the limiting member 600 to restrict the rotation of antenna 100.

[0136] Please continue reading Figures 15 to 17 As shown, in one possible implementation, a damping ring 434 is sleeved on the outer wall of the connecting part 431, and the damping ring 434 abuts between the outer wall of the connecting part 431 and the inner wall of the antenna 100.

[0137] The damping ring 434 can have a certain degree of elasticity. The inner wall of the antenna 100 and the outer wall of the connecting part 431 compress the damping ring 434, and the damping ring 434 generates a continuous elastic rebound force, so that the damping ring 434 abuts between the outer wall of the connecting part 431 and the inner wall of the antenna 100.

[0138] The compressed damping ring 434 creates a uniform and stable sliding friction force between the outer walls of the two connecting parts 431 and the inner wall of the antenna 100. When the antenna 100 rotates relative to the connecting parts 431, the uniform and stable sliding friction force generated by the compressed damping ring 434 provides continuous and balanced damping resistance to the rotation of the antenna 100. On the one hand, this friction force can counteract the wobbling caused by the antenna 100's own weight and assembly gaps, allowing the operator to precisely control the rotation angle and start / stop position of the antenna 100, resulting in a high degree of controllability during the antenna 100's rotation.

[0139] The sealing method between the first connector 410 and the first mounting wall 210 will be described in detail below.

[0140] Figure 18 for Figure 9 Enlarged view of point B in the middle.

[0141] See Figure 18 As shown, the first connector 410 includes a connector body 411, a first mounting plate 412, and a second mounting plate 413. The first mounting plate 412 and the second mounting plate 413 are both sleeved on the outer periphery of the connector body 411. The first mounting plate 412 is located on the side of the first mounting wall 210 facing the outside of the housing 200, and the second mounting plate 413 is located on the side of the first mounting wall 210 facing the receiving cavity. The first mounting plate 412 and the second mounting plate 413 are sealed and connected to the first mounting wall 210 respectively.

[0142] The connector body 411 is a structure for connecting the first connector 410 and the second connector 420. The connector body 411 can be cylindrical. The end of the connector body 411 facing the second connector 420 has external threads.

[0143] The first mounting plate 412 includes a first body 4121 and a first flange 4122 facing the second mounting plate 413, the inner wall of the first flange 4122 being connected to the outer wall of the connector body 411. The second mounting plate 413 includes a second body 4131 and a second flange 4132 facing the first mounting plate 412, the inner wall of the second flange 4132 being connected to the outer wall of the connector body 411.

[0144] The connector body 411 passes through the opening of the first mounting wall 210, which is sandwiched between the first body 4121 and the second body 4131. The first flange 4122 and the second flange 4132 partially pass through the opening of the first mounting wall 210, abutting against the connector body 411 and the inner wall of the opening. This allows for a reliable connection between the first connector 410 and the first mounting wall 210, preventing the first connector 410 from shifting within the opening.

[0145] The first connector 410 also includes a first sealing element 414 and a second sealing element 415. The first sealing element 414 abuts between the outer surfaces of the first body 4121 and the first mounting wall 210, providing a primary seal at the connection between the first connector 410 and the first mounting wall 210. The second sealing element 415 abuts between the second body 4131 and the inner wall of the first mounting wall 210, providing a secondary seal at the connection between the first connector 410 and the first mounting wall 210. This results in a better sealing effect between the first connector 410 and the first mounting wall 210, reducing the possibility of moisture, dust, etc., entering the receiving cavity from the connection between the antenna 100 and the housing 200, thus improving the protection reliability of the inverter 10. The end of the connector body 411 facing the inside of the receiving cavity is electrically connected to the second circuit board 320 via a first cable 500.

[0146] Please continue reading Figure 18 As shown, in one possible implementation, the connector body 411 also has a third flange 4111 at one end facing the interior of the receiving cavity, and a third seal 416 is provided between the third flange 4111 and the second mounting plate 413, thereby further improving the sealing effect.

[0147] Figure 19 This is another partial structural diagram of the antenna and housing in the inverter provided in the embodiments of this application.

[0148] See Figure 19 As shown, in one possible implementation, the first mounting wall 210 is provided with a protective flange 213 on the side facing the outside of the housing 200, and the protective flange 213 surrounds the outside of the first mounting plate 412.

[0149] The protective flange 213 can protrude from the outer surface of the first mounting wall 210. The protrusion height of the protective flange 213 can be greater than or equal to the thickness of the first body 4121 of the first mounting plate 412. The protective flange 213 can surround the outer side of the first mounting plate 412, and the protective flange 213 can be fitted to or spaced apart from the first mounting plate 412. The protective flange 213 can prevent rainwater, sand, etc. from directly impacting the connection between the first mounting plate 412 and the first mounting wall 210, thereby further improving the sealing effect.

[0150] The specific structure of antenna 100 will be described below.

[0151] Please continue reading Figures 6 to 16 As shown, the antenna 100 includes an antenna body 130 and a bend connector 140. One end of the bend connector 140 is connected to the antenna body 130, and the other end of the bend connector 140 is rotatably connected to the connector 430.

[0152] The angle connector 140 includes a first connecting segment 141 and a second connecting segment 142, which are connected and angled together. Figures 6 to 16 In the illustrated embodiment, the included angle between the first connecting segment 141 and the second connecting segment 142 is approximately 90°. The first connecting segment 141 is rotatably connected to the connector 430, the protrusion 110 is located on the outer periphery of the first connecting segment 141, and the second limiting platform 120 is located on the outer wall of the first connecting segment 141. The second connecting segment 142 is connected to the antenna body 130. When the first connecting segment 141 rotates relative to the connector 430, it can cause the second connecting segment 142 to rotate about the connection point between the first connecting segment 141 and the connector 430, allowing the antenna body 130 to rotate relative to the housing 200.

[0153] Antenna 100 also includes a radiator and a third circuit board. Antenna body 130 can be a hollow structure, and the third circuit board can be connected inside antenna body 130. The radiator is disposed on the third circuit board. The first connecting segment 141 and the second connecting segment 142 are both hollow structures, and the second cable passes through the first connecting segment 141 and the second connecting segment 142. The third circuit board is connected to the second connector 420 through the second cable, and then electrically connected to the second circuit board 320 through the first connector 410 and the first cable 500.

[0154] Figure 20 This is another schematic diagram of the inverter provided in an embodiment of this application. See also... Figure 20 As shown, when the antenna 100 is in the retracted state, the antenna 100 is located within the outer periphery of the housing 200. Please continue to see... Figure 4 As shown, when the antenna 100 is in working condition, the antenna 100 extends beyond the outer periphery of the housing 200.

[0155] Antenna 100 can be mounted on base plate 221. When antenna 100 is in operation, it can extend beyond the outer periphery of housing 200. For example, the projection of antenna 100 along the third direction Z can be partially located outside the projection contour of housing 200 along the third direction Z. When antenna 100 is in a retracted state, its projection along the third direction Z can be located on the inner wall of the projection contour of housing 200 along the third direction Z. This allows the inverter 10 to have a smaller size along the first direction X or the second direction Y, making it easier to store the inverter 10 in a packaging box during transportation.

[0156] Please continue reading Figure 4 and Figure 20As shown, in one possible implementation, the first mounting wall 210 is connected to the first side wall 2221 and bends from the first side wall 2221 toward the interior of the receiving cavity to form a receiving groove 240 in the region near the first mounting wall 210. When the antenna 100 is in the retracted state, the antenna 100 can rotate relative to the connector 430 to be located within the receiving groove 240 (e.g., Figure 20 (As shown).

[0157] The first mounting wall 210 can be located between the base plate 221 and the top cover 230 along the third direction Z. The wall surface of the first mounting wall 210 can be perpendicular to the third direction Z. The first mounting wall 210 is connected to the first side wall 2221 and extends from the first side wall 2221 toward the interior of the receiving cavity. Thus, a receiving groove 240 can be formed on the side of the first mounting wall 210 facing the base plate 221. The receiving groove 240 is formed by bending the first mounting wall 210 from the first side wall 2221 toward the interior of the receiving cavity. Therefore, the receiving groove 240 occupies part of the space of the receiving cavity and does not increase the outer contour of the housing 200. When the antenna 100 is in the retracted state, the antenna 100 can be located in the receiving groove 240. That is to say, setting the antenna 100 will not increase the size of the housing 200 along the third direction Z, making the structure of the inverter 10 more compact.

[0158] When assembling the inverter 10 and the battery pack 20, the second sidewall 2222 faces the battery pack 20, and the first terminal 10a is disposed on the second sidewall 2222, which facilitates the electrical connection between the first terminal 10a and the battery pack 20. In addition, the first terminal 10a and the antenna 100 are disposed on different sidewalls 222, so that the first terminal 10a will not interfere with the rotation of the antenna 100 and will not interfere with the signal of the antenna 100.

[0159] The second terminal 10b and the third terminal 10c are located on the third sidewall 2223, and the antenna 100 is located on the side of the first sidewall 2221 opposite to the third sidewall 2223.

[0160] The second terminal 10b and the third terminal 10c are both located on different sidewalls 222 from the antenna 100. Therefore, the second terminal 10b and the third terminal 10c will not interfere with the rotation of the antenna 100 or interfere with the signal of the antenna 100. Furthermore, since the second terminal 10b and the third terminal 10c are both located on the third sidewall 2223, the antenna 100 can be positioned away from the third sidewall 2223, thereby further reducing the interference of the second terminal 10b and the third terminal 10c on the rotation of the antenna 100 and the interference with the signal of the antenna 100.
