[0002] At present, the vehicle includes an on-board power supply, and the battery of the vehicle can charge the vehicle's storage battery through the on-board power supply. The on-board power supply includes a first direct current (DC) transformer, a second direct current transformer and a power factor correction (PFC) inductor. In the related art, when assembling the on-board power supply, it is necessary to install the first DC transformer, the second DC transformer, and the PFC inductor separately, and the process is complicated. In addition, since the first DC transformer, the second DC transformer, and the PFC inductor are large in size, it is also necessary to use an additional fixed structure to fix the first DC transformer, the second DC transformer, and the PFC inductor to the on-board power supply, respectively, resulting in too many parts and high costs, and is not conducive to the miniaturization of the on-board power supply, which in turn affects the vehicle's ability to improve space utilization.

[0003] Embodiments of the present application provide a charging module, a vehicle-mounted power supply, and a vehicle.

[0004] The charging module of the embodiment of the present application comprises a substrate, a first transformer, a power factor correction inductor and a second transformer. The first transformer, the power factor correction inductor and the second transformer are fixed on the substrate.

[0005] In this way, by fixing the first transformer, the power factor correction inductor and the second transformer to the substrate respectively, the first transformer, the power factor correction inductor and the second transformer which are independent of each other can be integrated into one device, so that the area occupied by the first transformer, the power factor correction inductor and the second transformer in the charging module can be reduced, which is conducive to the miniaturization of the vehicle power supply, thereby improving the space utilization of the vehicle, and the three are integrated into one device, which can collect the heat generated by the three and then process it, thereby improving the thermal management capability. Moreover, only one component, the substrate, is needed to fix the three, and no additional fixing structure is required, so the assembly is relatively simple and the development cost can be reduced.

[0006] In some embodiments, the substrate forms a limiting groove, and the first transformer, the power factor correction inductor and the second transformer are arranged in the limiting groove.

[0007] In this way, by forming a limiting groove on the substrate and arranging the first transformer, the power factor correction inductor and the second transformer in the limiting groove, the three can be conveniently fixed on the substrate, and the setting of the limiting groove can increase the area of ​​glue dispensing, thereby increasing the fixing strength.

[0008] In some embodiments, the first transformer, the power factor correction inductor and the second transformer are fixed on the substrate by dispensing glue.

[0009] In this way, by fixing the first transformer, the power factor correction inductor and the second transformer on the substrate using a glue-dispensing fixing method, there is no need to prepare additional fixing structures such as screws and screw holes, which reduces complicated processes, and the glue-dispensing fixing method is easy to assemble and disassemble.

[0010] In some embodiments, the first transformer, the power factor correction inductor and the second transformer each include a first pin, the substrate is formed with a through hole, and the charging module further includes a second pin, the second pin is arranged on a side of the substrate opposite to the first transformer, the power factor correction inductor and the second transformer, and at least a portion of the first pin passes through the through hole to be connected to the second pin.

[0011] In this way, by forming a through hole on the substrate, there is no need to connect the first pin included in the first transformer, the power factor correction inductor and the second transformer with the second pin from the outside of the substrate, so that the first pin can be connected to the second pin through the through hole, which saves costs and simplifies the structure of the charging module.

[0012] In some embodiments, the charging module also includes a pin adapter board, which is arranged on a side of the substrate opposite to the first transformer, the power factor correction inductor and the second transformer, and the pin adapter board is connected to at least part of the second pins, and at least part of the first pins are connected to the pin adapter board through the through hole.

[0013] In this way, by connecting the first pin to the pin adapter board through the through hole and the second pin to the pin adapter board, the first transformer, the power factor correction inductor and the second transformer can be conveniently connected to the external circuit.

[0014] In some embodiments, the charging module includes a magnetic sheet, the substrate is disposed between the magnetic sheet and the first transformer, the power factor correction inductor and the second transformer, and the first transformer is thermally coupled to the magnetic sheet through the pin adapter board.

[0015] In this way, by fixing the magnetic sheet included in the charging module on the substrate, the leakage magnetic field generated by the three coils can be effectively shielded. At the same time, the magnetic sheet has a high resistivity, which can reduce the eddy current loss of the magnetic sheet and reduce the heat generation.

[0016] In some embodiments, the substrate is formed with a fixed slot, and the magnetic sheet is located in the fixed slot.

[0017] In this way, by forming a fixed groove on the substrate, the magnetic sheet can be easily positioned on the substrate, thereby conveniently installing the magnetic sheet.

[0018] In some embodiments, the charging module includes a heat conductor, and the heat conductor is disposed between the substrate and the magnetic sheet.

[0019] In this way, by providing a heat conductor between the substrate and the magnetic sheet, the heat generated by the first transformer, the power factor correction inductor and the second transformer can be dissipated faster and can play a buffering role.

[0020] In some embodiments, the first transformer, the power factor correction inductor and the second transformer are fixed on the same side of the substrate, the charging module includes a shell, the shell forms a accommodating cavity, and when the substrate is connected to the shell, the first transformer, the power factor correction inductor and the second transformer are placed in the accommodating cavity.

[0021] In this way, by arranging the first transformer, the power factor correction inductor and the second transformer inside the shell, the first transformer, the power factor correction inductor and the second transformer can be prevented from being damaged due to external impact, thereby playing a protective role, and a water channel can be arranged in the accommodating cavity, so as to adopt water cooling to dissipate heat for the first transformer, the power factor correction inductor and the second transformer.

[0035] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

[0036] In the description of the present application, it should be understood that the terms "thickness", "upper", "top", "bottom", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0037] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. In an example, it can be a fixed connection, or a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection, or they can communicate with each other; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements.

[0038] In the embodiments of the present application, a first feature being “above” or “below” a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being “above”, “above”, and “above” a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0039] At present, when new energy vehicles are charging their batteries, two direct current (DC) transformers and power factor correction (PFC) inductors are required in the on-board power supply to convert the high-voltage alternating current in the charging pile into low-voltage direct current and store it in the battery.

[0040] When installing the first DC transformer, the second DC transformer and the PFC inductor, due to the large size of the first DC transformer, the second DC transformer and the PFC inductor, an additional fixing structure is required to fix the first DC transformer, the second DC transformer and the PFC inductor to the vehicle power supply respectively, resulting in too many components, high cost, and is not conducive to the miniaturization of the vehicle power supply, which in turn affects the vehicle's ability to improve space utilization.

[0041] To do this, see Figures 1 to 5 The charging module 11 of the embodiment of the present application includes a substrate 111, a first transformer 112, a power factor correction inductor 113 and a second transformer 114. The first transformer 112, the power factor correction inductor 113 and the second transformer 114 are fixed on the substrate 111.

[0042] In this way, by fixing the first transformer 112, the power factor correction inductor 113 and the second transformer 114 to the substrate 111 respectively, the first transformer 112, the power factor correction inductor 113 and the second transformer 114 which are independent of each other can be integrated into one device, so that the area occupied by the first transformer 112, the power factor correction inductor 113 and the second transformer 114 in the charging module 11 can be reduced, which is conducive to the miniaturization of the vehicle power supply 10, and then improves the space utilization of the vehicle 100, and the three are integrated into one device, which can collect and process the heat generated by the three, and improve the thermal management capability. Moreover, only one component, the substrate 111, is needed to fix the three, and no additional fixing structure is required, so the assembly is relatively simple and the development cost can be reduced.

[0043] The on-board power supply 10 of the vehicle 100 includes a charging module 11 which includes a first transformer 112, a power factor correction inductor 113, and a second transformer 114. The on-board power supply 10 of the vehicle 100 can receive external current signals through the input charging module 11, and convert the current signals in the charging module 11 and transmit them to the battery of the vehicle 100 for charging. The first transformer 112 and the second transformer 114 can be DC transformers. Figure 7 As shown, when the vehicle 100 is being charged, when the high-voltage alternating current in the charging pile flows through the power factor correction inductor 113, the power factor correction inductor 113 can adjust the lower voltage waveform and harmonics in the high-voltage alternating current, so that the waveform of the high-voltage alternating current is close to a sine wave; after the high-voltage alternating current passes through the power factor correction circuit, a direct current is formed, which is converted into high-voltage direct current by the first transformer 112 and stored in the power battery, and is converted into low-voltage direct current by the second transformer 114 and stored in the battery.

[0044] Specifically, the charging module 11 of the vehicle 100 also includes a substrate 111. The shape of the substrate 111 needs to be adapted to the shapes of the first transformer 112, the power factor correction inductor 113, and the second transformer 114, so that the substrate 111 can fix the first transformer 112, the power factor correction inductor 113, and the second transformer 114, thereby eliminating the need for an additional fixing structure. The substrate 111 can be made by an injection molding manufacturing process, thereby improving the production efficiency of the substrate 111, reducing the cost of producing the substrate 111, and stabilizing the production quality of the substrate 111.

[0045] A limiting groove 1111 is also formed on the substrate 111. The size and shape of the limiting groove 1111 correspond to the first transformer 112, the power factor correction inductor 113 and the second transformer 114, respectively. By extending at least part of the first transformer 112, the power factor correction inductor 113 and the second transformer 114 into the limiting groove 1111, the first transformer 112, the power factor correction inductor 113 and the second transformer 114 can be quickly fixed on the substrate 111. Moreover, the limiting groove 1111 is provided on the substrate 111, which can increase the contact area between the first transformer 112, the power factor correction inductor 113 and the second transformer 114 and the substrate 111, thereby increasing the fixing strength.

[0046] The first transformer 112, the power factor correction inductor 113, and the second transformer 114 can be fixed to the limiting groove 1111 by glue dispensing, that is, after the first transformer 112, the power factor correction inductor 113, and the second transformer 114 are inserted into the limiting groove 1111, the glue dispensing machine injects glue into the limiting groove 1111, so that the first transformer 112, the power factor correction inductor 113, and the second transformer 114 can be fixed on the substrate 111 after the glue cools down. Therefore, by fixing the first transformer 112, the power factor correction inductor 113, and the second transformer 114 on the substrate 111 by glue dispensing, there is no need to prepare additional fixing structures such as screws and screw holes, which reduces complicated processes, and the glue dispensing fixing method makes it easy to assemble and disassemble the first transformer 112, the power factor correction inductor 113, and the second transformer 114 and the substrate 111.

[0047] See also Figure 2 In some embodiments, the first transformer 112, the power factor correction inductor 113 and the second transformer 114 all include a first pin 115, the substrate 111 is formed with a through hole 1113, and the charging module 11 also includes a second pin 117. The second pin 117 is arranged on the side of the substrate 111 opposite to the first transformer 112, the power factor correction inductor 113 and the second transformer 114, and at least part of the first pin 115 passes through the through hole 1113 to be connected to the second pin 117.

[0048] In this way, by forming a through hole 1113 on the substrate 111, there is no need to connect the first pin 115 included in the first transformer 112, the power factor correction inductor 113 and the second transformer 114 to the second pin 117 from the outside of the substrate 111, so that the first pin 115 can pass through the through hole 1113 to be connected to the second pin 117, which saves costs and simplifies the structure of the charging module 11.

[0049] Specifically, in order for the charging module 11 to communicate with the external circuit, it is necessary to set a pin on the charging module 11 as a connection bridge. The first transformer 112, the power factor correction inductor 113 and the second transformer 114 are all provided with a first pin 115, and the first pin 115 can be used as an interface for connecting the circuits in the first transformer 112, the power factor correction inductor 113 and the second transformer 114 with the external circuit, and the number of the first pins 115 of the first transformer 112, the power factor correction inductor 113 and the second transformer 114 is different. For example, the number of the first pins 115 of the first transformer 112 can be 4, the number of the first pins 115 of the second transformer 114 can be 6, and the number of the first pins 115 of the power factor correction inductor 113 can be 2.

[0050] See also Figure 2 In some embodiments, the charging module 11 also includes a pin adapter board 116, which is arranged on the side of the substrate 111 opposite to the first transformer 112, the power factor correction inductor 113 and the second transformer 114. The pin adapter board 116 is connected to at least part of the second pin 117, and at least part of the first pin 115 is connected to the pin adapter board 116 through the through hole 1113.

[0051] In this way, by connecting the first pin 112 to the pin adapter board 116 through the through hole 1113 and the second pin 117 to the pin adapter board 116, the first transformer 112, the power factor correction inductor 113 and the second transformer 114 can be conveniently connected to the external circuit.

[0052] The charging module 11 also includes a pin adapter board 116, and the position of the pin adapter board 116 is set on the side of the substrate 111 that is opposite to the first transformer 112, the power factor correction inductor 113 and the second transformer 114, and corresponds to the position of the first pin 115 of the second transformer 114. A through hole 1113 is also formed on the substrate 111, and a positioning hole 1161 is formed on the pin adapter board 116. The position of the through hole 1113 is set between the pin adapter board 116 and the first pin 115, so that the first pin 115 can pass through the through hole 1113 and be fixedly connected to the positioning hole 1161 on the pin adapter board 116, and the second pin 117 is stably connected to the pin adapter board 116, so that the pin adapter board 116 can play a role in stably connecting the first transformer 112, the power factor correction inductor 113 and the second transformer 114 with the external circuit.

[0053] Optionally, the second transformer 114 includes a secondary copper sheet. A positioning hole 1161 is provided on the pin adapter plate 116 corresponding to the second transformer 114, and the shape and size of the positioning hole 1161 match the shape and size of the secondary copper sheet 1141. For example, the secondary copper sheet 1141 is rectangular, and the shape of the positioning hole 1161 is also rectangular. Thus, the secondary copper sheet 1141 can pass through the through hole 1113 on the substrate 111 and the positioning hole 1161 on the magnetic sheet 118 in sequence.

[0054] See also Figure 2 and Figure 5 In some embodiments, the charging module 11 includes a magnetic sheet 118 , and the substrate 111 is disposed between the magnetic sheet 118 and the first transformer 112 , the power factor correction inductor 113 , and the second transformer 114 , and the first transformer 112 is thermally coupled to the magnetic sheet 118 via a pin adapter board 116 .

[0055] In this way, by fixing the magnetic sheet 118 included in the charging module 11 on the substrate 111, the leakage magnetic field generated by the three coils can be effectively shielded. At the same time, the magnetic sheet 118 has a high resistivity, which can reduce the eddy current loss of the magnetic sheet 118 and reduce the heat generation.

[0056] Specifically, the charging module 11 further includes a magnetic sheet 118 , which is made of a magnetic material and has high magnetic permeability and high resistivity.

[0057] A fixing slot 1112 is further formed on the substrate 111 on the side opposite to the first transformer 112, the power factor correction inductor 113 and the second transformer 114. The shape and size of the fixing slot 1112 match the shape and size of the magnetic sheet 118, so that the magnetic sheet 118 can be inserted into the fixing slot 1112 for fixing. By forming the fixing slot 1112 on the substrate 111, the positioning of the magnetic sheet 118 on the substrate 111 can be facilitated, so that the magnetic sheet 118 can be quickly installed.

[0058] Optionally, the pin adapter plate 116 located above the first transformer 112 can be set around the magnetic sheet 118, so that the heat generated by the first transformer 112 can be transferred to the magnetic sheet 118 by heat conduction, so that the heat generated by the direct current can be dissipated through the magnetic sheet 118.

[0059] In some embodiments, the charging module 11 includes a heat conductor, which is disposed between the substrate 111 and the magnetic sheet 118 .

[0060] In this way, by providing a heat conductor between the substrate 111 and the magnetic sheet 118 , the heat generated by the first transformer 112 , the power factor correction inductor 113 and the second transformer 114 can be dissipated more quickly.

[0061] Specifically, the charging module 11 also includes a heat conductive member, which may be an organic thermal conductive silicone grease, an inorganic thermal conductive silicone grease, a composite thermal conductive silicone grease, a thermal conductive pad, etc. The heat conductive member is disposed on the substrate 111 below the magnetic sheet 118, so that when the heat generated by the first transformer 112, the power factor correction inductor 113, and the second transformer 114 is transferred to the substrate 111, the heat dissipation can be accelerated through the heat conductive member.

[0062] Please refer again Figure 2 In some embodiments, the first transformer 112, the power factor correction inductor 113 and the second transformer 114 are fixed on the same side of the substrate 111, and the charging module 11 includes a shell 119, and the shell 119 is formed with a accommodating cavity 1191. When the substrate 111 is connected to the shell 119, the first transformer 112, the power factor correction inductor 113 and the second transformer 114 are placed in the accommodating cavity 1191.

[0063] In this way, by arranging the first transformer 112, the power factor correction inductor 113 and the second transformer 114 inside the shell 119, the first transformer 112, the power factor correction inductor 113 and the second transformer 114 can be prevented from being damaged due to external impact, thereby playing a protective role, and a water channel can be arranged in the accommodating cavity, so that the first transformer 112, the power factor correction inductor 113 and the second transformer 114 can be water-cooled.

[0064] Specifically, the charging module 11 also includes a shell 119, which can form a accommodating cavity 1191. The size and shape of the shell 119 are adapted to the size and shape of the first transformer 112, the power factor correction inductor 113 and the second transformer 114, so that the first transformer 112, the power factor correction inductor 113 and the second transformer 114 can be arranged in the accommodating cavity 1191.

[0065] The opening of the shell 119 can be connected to the side of the substrate 111 by bolts, welding or riveting, so that the substrate 111 and the shell 119 can surround the first transformer 112, the power factor correction inductor 113 and the second transformer 114, and thus when the vehicle 100 is bumped or hit, the first transformer 112, the power factor correction inductor 113 and the second transformer 114 can be protected from damage.

[0066] See also Figure 6 The vehicle 100 of the embodiment of the present application includes the charging module 11 of the above embodiment.

[0067] Specifically, according to the vehicle 100 of the embodiment of the present application, the charging module 11 of the above embodiment can integrate the three independent devices of the first transformer 112, the power factor correction inductor 113 and the second transformer 114 into one device through the substrate 111, so that no additional fixing structure is required to fix the first transformer 112, the power factor correction inductor 113 and the second transformer 114 respectively, thereby reducing the occupied area, facilitating the miniaturization of the on-board power supply 10, improving the space utilization of the vehicle 100, and reducing the cost required for additional fixing structures, and can conveniently collect the heat generated by the first transformer 112, the power factor correction inductor 113 and the second transformer 114, thereby improving the thermal management capability of the vehicle 100.

[0068] Optionally, the location of the vehicle power supply 10 is not affected by Figure 6 The limitations described above mean that the vehicle-mounted power supply 10 can be disposed at the bottom of the trunk of the vehicle 100 , or can be disposed under the rear seats of the vehicle 100 .
