[0060] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0061] In the description of the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0062] In addition, the direction descriptions mentioned below are all based on the directions of the illustrations attached to the specification, such as the first direction indicated by the Z-axis direction of the illustration, the second direction indicated by the X-axis direction of the illustration, and the third direction indicated by the Y-axis direction of the illustration. This is intended to describe the present solution more clearly, but does not limit the specific direction of the product in use.

[0063] In the related art, the energy storage inverter usually includes a casing, a DC connector and a fuse, wherein the DC connector is installed on the side wall of the casing, and the fuse is installed on the bottom wall of the casing. The fuse is usually installed horizontally, that is, the length direction of the fuse is parallel to the extension direction of the bottom wall of the casing, that is, the fuse as a whole is parallel to the length direction of the casing, resulting in the fuse occupying more space in the length direction of the casing, reducing the space utilization rate.

[0064] In the above situation, if a circuit board with built-in electronic devices needs to be installed in the casing, such as an electromagnetic compatibility board with filtering function (also called DC-EMC board), the height of the casing needs to be greatly increased, resulting in an increase in the size of the casing, higher production costs and inconvenience in use; at the same time, if the electromagnetic compatibility board is not installed in the casing in order to save space, the EMC frequency impedance characteristics cannot be improved, and it is difficult to meet the needs of EMC filtering, so there is a technical contradiction.

[0065] To this end, the present application first provides an energy storage inverter, which has the technical effects of improving space utilization and improving EMC frequency impedance characteristics.

[0066] See also Figure 1 and Figure 2 The energy storage converter includes a housing 10, a connector 20, a fuse 30 and a circuit board 40. The housing 10 is made of a conductive material, and is provided with a receiving groove 11. The receiving groove 11 penetrates one side of the housing 10 to form a notch. The housing 10 can cooperate with a housing cover (not shown in the figure) to block the notch of the receiving groove 11. The groove wall of the receiving groove 11 forms the side wall of the inner side of the housing 10, and the groove bottom of the receiving groove 11 forms the bottom wall of the inner side of the housing 10. The inner side of the housing 10 has a first surface 12 extending along a first direction and a second surface 13 extending along a second direction, and there is an angle between the first direction and the second direction. Exemplarily, the first direction is the height direction of the housing 10, which is indicated by the Z-axis direction in the figure. The second direction is the length direction of the housing 10, which is indicated by the X-axis direction in the figure. The side wall of the housing 10 is the first surface 12, and the bottom wall of the housing 10 is the second surface 13, and the first surface 12 and the second surface 13 are perpendicular to each other.

[0067] The connector 20 is disposed on the first surface 12. One end of the connector 20 is located inside the housing 10 to connect with the fuse 30, and the other end of the connector 20 is exposed outside the housing 10 to connect with an energy storage module outside the housing 10. The energy storage module may be a battery pack, a battery cell, etc.

[0068] The fuse 30 is arranged in the housing 10, and the fuse 30 is arranged parallel to the second direction, that is, the length direction of the fuse 30 is parallel to the first direction, that is, the fuse 30 is arranged in a vertical installation manner. The fuse 30 has a first power terminal 31 and a second power terminal 32, and the first power terminal 31 and the second power terminal 32 are distributed along the first direction, wherein the first power terminal 31 is connected to the connector 20, and the second power terminal 32 is connected to the circuit board 40.

[0069] The circuit board 40 is an electromagnetic compatibility board with a filtering function. The circuit board 40 is arranged in the housing 10, and the circuit board 40 is spaced apart from and parallel to the second surface 13, and the side of the circuit board 40 facing the second surface 13 is provided with electronic components 41, that is, the circuit board 40 is arranged in an inverted installation manner. The circuit board 40 is used to connect the power board outside the housing 10.

[0070] By using the energy storage converter provided by the present application, the fuse 30 is arranged parallel to the second direction, reducing the occupation of the fuse 30 in the length direction of the housing 10, so as to leave more space in the housing 10 to accommodate the electronic components 41 located on the surface of the circuit board 40, so that the distribution between the fuse 30, the circuit board 40 and the electronic components 41 is more compact, and the space utilization rate is improved. More space can also be left in the length direction of the housing 10 to accommodate other electronic devices, such as the relay 17.

[0071] Furthermore, the overall size of the housing 10 is reduced on the basis of meeting the requirements for installing the circuit board 40 , and the circuit board 40 is used to implement a filtering function, adjust the input impedance, and improve the EMC frequency impedance characteristics.

[0072] See also Figure 1 and Figure 3 In this embodiment, the energy storage current device further includes a magnetic ring 50 and a conductive frame 60, both of which are arranged on the first surface 12, wherein the magnetic ring 50 is distributed around the connector 20, one end of the connector 20 is passed through the magnetic ring 50 and connected to the fuse 30, and the magnetic ring 50 can play a high-frequency filtering role. The conductive frame 60 is fixed to the housing 10, and the conductive frame 60 is used to fix the magnetic ring 50 to prevent the magnetic ring 50 from being separated from the connector 20.

[0073] See also Figure 1 and Figure 2 In some embodiments, the connector 20 is embedded in the first surface 12 of the housing 10 , one end of the connector 20 is located in the housing 10 and is provided with a connecting terminal 21 , the connecting terminal 21 is used to connect to the fuse 30 , and the other end of the connector 20 is exposed outside the housing 10 .

[0074] Exemplarily, there are two connectors 20, and the two connectors 20 are divided into a positive connector and a negative connector. The two connectors 20 are spaced apart along the third direction. The third direction is the width direction of the housing 10, which is indicated by the Y-axis direction in the figure. One end of the connector 20 located in the housing 10 is provided with a connection terminal 21 extending along the first direction. The end of the connection terminal 21 is provided with a connection hole, and the connection terminal 21 can be fixed with other structures through the connection hole, and the connection terminal 21 can be electrically connected with other components by contact.

[0075] In some embodiments, the magnetic ring 50 is located on the first surface 12 of the housing 10. The shape of the magnetic ring 50 corresponds to the distribution of the connector 20, the connection terminal 21 of the connector 20 is inserted into the inner ring of the magnetic ring 50, and there is a gap between the inner side of the magnetic ring 50 and the connector 20. Exemplarily, the magnetic ring 50 is waist-shaped as a whole, and the length direction of the magnetic ring 50 corresponds to the third direction.

[0076] See also Figure 1 and Figure 3 In some embodiments, the conductive frame 60 is fixedly connected to the first surface 12 of the housing 10. The conductive frame 60 is provided with a mounting groove 61, the notch of the mounting groove 61 is arranged toward the first surface 12, and the magnetic ring 50 is received in the mounting groove 61. In this way, the conductive frame 60 is fixed to the side wall of the housing 10, and the housing 10 blocks the notch of the mounting groove 61, so that the magnetic ring 50 is fixed to the first surface 12.

[0077] In some embodiments, the inner size of the mounting groove 61 is larger than the size of the magnetic ring 50. When the magnetic ring 50 is received in the mounting groove 61, a gap is left between the inner wall of the mounting groove 61 and at least one side of the magnetic ring 50, so that the risk of the magnetic ring 50 being unable to be installed in the conductive frame 60 due to a large tolerance can be avoided.

[0078] In some embodiments, a buffer pad 70 is provided in the mounting groove 61, and the buffer pad 70 is bonded and fixed to the conductive frame 60, and the buffer pad 70 is used to press the magnetic ring 50. The buffer pad 70 plays a buffering and protective role on the magnetic ring 50 to prevent the magnetic ring 50 from being damaged during the transportation, collision, and falling of the housing 10.

[0079] The exemplary conductive frame 60 includes a frame portion 62 and an enclosure portion 63. The frame portion 62 is arranged to correspond to the shape of the magnetic ring 50. A through hole for the connector 20 to pass through is arranged in the middle of the frame portion 62. The enclosure portion 63 is arranged along the circumference of the frame portion 62. There is an angle between the enclosure portion 63 and the frame portion 62. The frame portion 62 and the enclosure portion 63 enclose a mounting groove 61. The enclosure portion 63 is fixedly connected to the housing 10. There are multiple enclosure portions 63, and the multiple enclosure portions 63 are spaced apart along the circumference of the frame portion 62. The enclosure portion 63 and the frame portion 62 can be formed as a whole by a metal plate through a bending process to reduce processing costs.

[0080] The side of the enclosure 63 away from the frame 62 is fixed to the housing 10 by screw bolts. It can be understood that the fixing method between the conductive frame 60 and the housing 10 is a detachable connection, which is convenient for users to subsequently disassemble the conductive frame 60 or the magnetic ring 50 for inspection and maintenance.

[0081] In some embodiments, the number of buffer pads 70 is ≥ 2, the multiple buffer pads 70 are located at different positions, and the multiple buffer pads 70 can be divided into a first buffer pad 71 and a second buffer pad 72, and the first buffer pad 71 and the second buffer pad 72 are respectively used to press the magnetic ring 50 along different directions.

[0082] Exemplarily, the first buffer pad 71 is arranged on the enclosure portion 63, and the second buffer pad 72 is arranged on the frame portion 62. The enclosure portion 63 presses the outer side of the magnetic ring 50 along the first direction through the first buffer pad 71, and the frame portion 62 presses the outer side of the magnetic ring 50 along the second direction through the second buffer pad 72. In this way, the conductive frame 60 as a whole and the casing 10 can cooperate to squeeze and fix the magnetic ring 50 from multiple directions, thereby improving the supporting and fixing effect and the buffering effect.

[0083] See also Figure 1 and Figure 4 In some embodiments, the main body of the fuse 30 is in the shape of a rectangular parallelepiped, and the length direction of the fuse 30 is parallel to the second direction. The fuse 30 is provided with power terminals at both ends in the length direction, and the power terminals are provided with threaded holes. The power terminals can be fixed with the screw structure through the threaded holes, and the power terminals can be electrically connected with other electronic devices through contact. Among them, the power terminal located at the end of the fuse 30 close to the second surface 13 forms a first power terminal 31, and there is a distance between the first power terminal 31 and the second surface 13, and the power terminal located at the end of the fuse 30 far from the second surface 13 forms a second power terminal 32.

[0084] Exemplarily, the number and distribution of fuses 30 correspond to the number and distribution of connectors 20, that is, there are two fuses 30, which are divided into a positive fuse and a negative fuse, wherein the positive fuse is connected to the positive connector and the negative fuse is connected to the negative connector.

[0085] In some embodiments, the energy storage converter further includes a conductive seat 80, which is used to establish an electrical connection between the fuse 30 and the connector 20. The conductive seat 80 has a port section 81, a connecting section 82, a first fixed section 83, and a second fixed section 84. The connecting section 82 extends along a first direction, the port section 81 and the first fixed section 83 are respectively located at two ends of the connecting section 82, and the second fixed section 84 is located at an end of the first fixed section 83 away from the connecting section 82. The port section 81 is connected to the connector 20, the first fixed section 83 is connected to the first power terminal 31, and the first fixed section 83 is used to be fixedly connected to the housing 10 to support the fuse 30, and the second fixed section 84 can also be fixedly connected to the housing 10 to further improve the support strength of the fuse 30.

[0086] Exemplarily, the port section 81, the first fixed section 83 and the second fixed section 84 are all parallel to the first surface 12, the conductive seat 80 is integrally formed of a metal material, and the port section 81, the connecting section 82 and the first fixed section 83 can be formed by a bending process. The conductive seat 80 can be electrically connected by contacting other electronic devices.

[0087] See also Figure 1 , Figure 2 and Figure 4 The port section 81 is provided with a fixing hole 811, and the port section 81 can be fixed with the screw structure through the fixing hole 811. The port section 81 is pressed against the side of the connection terminal 21 away from the second surface 13, and the port section 81 and the connection terminal 21 are connected and fixed by fixing screws, so that the port section 81 and the connection terminal 21 are fixed and electrically connected, thereby realizing the electrical connection between the connector 20 and the fuse 30.

[0088] It can be understood that the port section 81, the connection section 82 and the first fixing section 83 can make up for the height difference between the first power terminal 31 and the connector 20 in the first direction, and ensure the normal connection between the fuse 30 and the connector 20. At the same time, the conductive seat 80 has a certain mechanical strength, which can support and fix the fuse 30, thereby improving the stability of the fuse 30.

[0089] In some embodiments, a mounting hole is provided at one end of the first fixing section 83 away from the connecting section 82, the mounting hole penetrates the first fixing section 83 along the first direction, and the mounting hole is provided corresponding to the threaded hole of the first power connection terminal 31. The fuse 30 is provided with a fastening screw 812, which is passed through the mounting hole and is threadedly connected to the first power connection terminal 31. In this way, the conductive holder 80 is detachably connected to the fuse 30 through the fastening screw 812, which facilitates the user to subsequently disassemble the fuse 30 or the conductive holder 80 for inspection and maintenance.

[0090] In some embodiments, a positioning pin 85 is provided on one side of the first fixing section 83 facing the fuse 30, and the positioning pin 85 extends along the second direction. The distance between the positioning pin 85 and the axis a of the mounting hole is greater than the minimum distance between the peripheral side of the fuse 30 and the axis a of the mounting hole, and the distance between the positioning pin 85 and the axis a of the mounting hole is less than the maximum distance between the peripheral side of the fuse 30 and the axis a of the mounting hole.

[0091] Exemplarily, the cross-section of the fuse 30 is rectangular as a whole, the distance between the midpoint of the rectangular edge of the fuse 30 and the axis a is smaller than the distance between the locating pin 85 and the axis a of the mounting hole, and the distance between the rectangular corner point of the fuse 30 and the axis a is greater than the distance between the locating pin 85 and the axis a of the mounting hole.

[0092] In this way, when the first fixing section 83 and the fuse 30 rotate relative to each other around the axis of the mounting hole, the positioning pin 85 can abut against the circumferential side of the fuse 30, so that the first fixing section 83 and the fuse 30 are circumferentially fixed. In this embodiment, a positioning pin 85 is also provided on the side of the second fixing section 84 facing the fuse 30, and a plurality of positioning pins 85 simultaneously restrict the relative rotation of the first fixing section 83 and the fuse 30.

[0093] In this way, when the fastening screw 812 passes through the first fixing section 83 and rotates relative to the first power terminal 31, the positioning pin 85 can limit the relative rotation of the first fixing section 83 and the fuse 30, preventing the first fixing section 83 and the fuse 30 from rotating at the same time, causing the fastening screw 812 to be unable to be tightened or loosened, thereby facilitating the disassembly and assembly of the fuse 30 and the conductive seat 80.

[0094] It is worth noting that the number and distribution of the conductive seats 80 correspond to the number and distribution of the fuses 30. In the example of this embodiment, there are two conductive seats 80, which can be divided into a positive conductive seat and a negative conductive seat, wherein the positive conductive seat is set on the positive fuse and the negative conductive seat is set on the negative fuse.

[0095] See also Figure 4 and Figure 5 In some embodiments, the energy storage converter further includes a first insulating column 15, wherein the first insulating column 15 is arranged corresponding to the first fixed section 83, and the first fixed section 83 and the second surface 13 are respectively connected to the two ends of the first insulating column 15. Exemplarily, one end of the first fixed section 83 close to the connecting section 82 is fixedly connected to the first insulating column 15 through a screw structure, and the first insulating column 15 is bolted and fixed to the second surface 13 of the housing 10. It can be understood that the first insulating column 15 can support the first fixed section 83 to maintain the distance between the conductive seat 80 and the housing 10 to play an insulating role.

[0096] In some embodiments, the energy storage converter further includes a second insulating column 16, wherein the second insulating column 16 is provided corresponding to the second fixing section 84, and the second fixing section 84 and the second surface 13 are respectively connected to both ends of the second insulating column 16. Exemplarily, one end of the second fixing section 84 close to the fuse 30 is fixedly connected to the second insulating column 16 through a screw structure, and the second insulating column 16 is bolted and fixed to the second surface 13 of the housing 10.

[0097] It can be understood that the first insulating column 15 and the second insulating column 16 cooperate to support the first fixing section 83 and the second fixing section 84 respectively, thereby improving the installation stability of the conductive seat 80. In addition, the connection between the first fixing section 83, the second fixing section 84, the first insulating column 15, the second insulating column 16 and the housing 10 is a detachable connection, which is convenient for the user to subsequently disassemble the conductive seat 80 for inspection and maintenance.

[0098] On the other hand, since the distance between the locating pin 85 and the axis a of the mounting hole is greater than the minimum distance between the peripheral side of the fuse 30 and the axis a of the mounting hole, a certain gap space can be reserved between the locating pin 85 and the peripheral side of the fuse 30 to allow the fuse 30 and the conductive seat 80 to rotate within a certain range, thereby reducing the angle restriction between the conductive seat 80 and the fuse 30 and facilitating the installation of the conductive seat 80.

[0099] See also Figure 1 , Figure 4 and Figure 6 In some embodiments, a distance is left between the circuit board 40 and the second surface 13 to form a space for accommodating the electronic component 41, and the distance from the circuit board 40 to the second surface 13 corresponds to the distance from the second power terminal 32 of the fuse 30 to the second surface 13, so as to facilitate the establishment of a connection between the circuit board 40 and the second power terminal 32.

[0100] It is worth noting that the electronic components 41 are arranged on the side of the circuit board 40 facing the second surface 13 mentioned in the present application, which does not limit the circuit board 40 to be provided with electronic components 41 only on the side facing the second surface 13, but indicates that electronic components 41 with a certain volume such as common-mode inductors 411, X capacitors 412, and Y capacitors 413 are located on the side of the circuit board 40 facing the second surface 13, and the electronic components 41 can also be arranged on the side of the circuit board 40 away from the second surface 13.

[0101] In some embodiments, the energy storage converter further includes a plurality of support rods 14, the support rods 14 are extended along the first direction, and the plurality of support rods 14 are spaced apart along the circumference of the circuit board 40. One end of the support rod 14 is connected to the second surface 13 of the housing 10, and the other end of the support rod 14 is connected to the circuit board 40. Exemplarily, the second surface 13 of the housing 10 is provided with a sleeve for the support rod 14 to be inserted, one end of the support rod 14 is inserted into the sleeve, and the other end of the support rod 14 is bolted and fixed to the circuit board 40.

[0102] It can be understood that the plurality of support rods 14 simultaneously support the circuit board 40, maintain the spacing between the circuit board 40 and the second surface 13, and improve the stability of the circuit board 40. In addition, the support rods 14 and the circuit board 40 are detachably connected, which facilitates the user to subsequently disassemble the circuit board 40 for inspection and maintenance.

[0103] In some embodiments, the support rod 14 is made of metal material, and the circuit board 40 is electrically connected to the housing 10 through the support rod 14 to achieve grounding.

[0104] In some embodiments, a conductive terminal 42 is welded to one end of the circuit board 40 close to the fuse 30, and the conductive terminal 42 is used to be electrically connected to the second power terminal 32 of the fuse 30. A clearance hole 43 is also provided on the side of the circuit board 40 close to the conductive terminal 42, and the clearance hole 43 is used to pass through and accommodate the fuse 30. The number and distribution of the conductive terminals 42 and the clearance holes 43 correspond to the number and distribution of the fuses 30.

[0105] Exemplarily, the number of the conductive terminals 42 is 2, and the two conductive terminals 42 are divided into a positive conductive terminal and a negative conductive terminal, wherein the positive conductive terminal is used to connect to the positive fuse, and the negative conductive terminal is used to connect to the negative fuse. Correspondingly, the circuit board 40 is provided with clearance holes 43 on both sides in the third direction, and the two clearance holes 43 are respectively used to pass through and accommodate the positive fuse and the negative fuse.

[0106] In some embodiments, the energy storage converter further includes a conductive member 90, the conductive member 90 has a deformable ability, and the circuit board 40 and the fuse 30 are respectively connected to the two ends of the conductive member 90. Exemplarily, the conductive terminal 42 is provided with a perforation. The conductive member 90 can be a soft copper bar, one end of which is fixed to the second power terminal 32 of the fuse 30 by screw bolting and is electrically connected to the second power terminal 32, and the other end of the soft copper bar is fixed to the conductive terminal 42 by screw bolting and is electrically connected to the conductive terminal 42, thereby establishing an electrical connection between the fuse 30 and the conductive terminal 42.

[0107] It can be understood that the height difference between the circuit board 40 and the second power terminal 32 can be compensated by utilizing the deformable characteristic of the conductive member 90, so as to prevent the circuit board 40 from being unable to connect to the second power terminal 32 due to tolerance problems. At the same time, the fixing method between the conductive member 90, the fuse 30 and the circuit board 40 is a detachable connection, which is convenient for the user to subsequently disassemble the fuse 30 or the circuit board 40 for inspection and maintenance.

[0108] In some embodiments, there is an angle between the first fixing section 83 and the second fixing section 84 of the conductive seat 80. For example, the first fixing section 83 is perpendicular to the second fixing section 84. In this way, the conductive member 90, the first fixing section 83 and the second fixing section 84 can form a triangular support structure relative to the fuse 30 to provide more stable support for the fuse 30, while making the distribution of the first fixing section 83 and the second fixing section 84 more compact, thereby improving space utilization.

[0109] In some embodiments, a connecting copper bar is provided at one end of the circuit board 40 away from the conductive terminal 42, and the connecting copper bar is used to connect to an external power board. Exemplarily, the connecting copper bar is bolted and fixed to the circuit board 40, and the number of the connecting copper bars is 2, and the two connecting copper bars can be divided into a positive connecting copper bar and a negative connecting copper bar, and the positive connecting copper bar and the negative connecting copper bar are used to connect to the positive and negative electrodes of the power board respectively.

[0113] Then, the circuit board 40 is mounted upside down on the support rod 14 , and the conductive member 90 is installed between the circuit board 40 and the fuse 30 .
