[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0048] The embodiment of the present application provides an on-board charger, a vehicle controller including the on-board charger, and a vehicle including the vehicle controller, wherein the vehicle may be a car, a bus, or a truck. For example, the vehicle may be any one of an electric vehicle / electric vehicle (EV), a pure electric vehicle / battery electric vehicle (PEV / BEV), a hybrid electric vehicle (HEV), a range extended electric vehicle (REEV), a plug-in hybrid electric vehicle (PHEV), and a new energy vehicle (NEV).

[0049] As described in the above background technology, the charger usually includes a housing and a charger body disposed in the housing. The housing of the charger usually includes a lower housing and an upper end cover, and the lower housing and the upper cover are together formed to form a receiving cavity, and the charger body is located in the receiving cavity. The charger body is used to charge the battery, and the housing is used to accommodate the charger body to achieve installation and fixation of the charger body. Usually, the charger is set separately in the vehicle.

[0050] However, in the above-mentioned charger, the shell structure is relatively large and heavy, which is not conducive to the lightweight design of the charger and increases the cost of the charger.

[0051] Based on the above problems, an embodiment of the present application provides a vehicle-mounted charger. By making the vehicle-mounted charger include a bottom plate, and making the vehicle-mounted charger detachably connected to the vehicle controller through the bottom plate, there is no need to set a shell in the vehicle-mounted charger. It is only necessary to set the bottom plate to connect with the shell connected to the vehicle controller. The upper end cover of the vehicle-mounted charger, the side wall of the lower shell and other structures can be omitted, which can effectively reduce the structure of the vehicle-mounted charger and reduce the weight of the vehicle-mounted charger, thereby effectively realizing the lightweight design of the vehicle-mounted charger and effectively reducing the material cost of the vehicle-mounted charger.

[0052] The following is a detailed description of the on-board charger provided in the embodiment of the present application in conjunction with the accompanying drawings.

[0053] Figure 1 A schematic diagram of the structure of a vehicle charger provided in an embodiment of the present application is shown in FIG. Figure 2 A schematic diagram of the structure of a vehicle controller provided in an embodiment of the present application is shown in FIG. Figure 3 A schematic diagram of the structure of a vehicle-mounted charger provided in a vehicle controller according to an embodiment of the present application.

[0054] The embodiment of the present application provides a vehicle charger 100, which can be used in a vehicle controller 200. Figure 1 As shown, the vehicle charger 100 may include a base plate 110 and a charger body 120, and the charger body 120 may be located on the base plate 110 and detachably connected to the base plate 110. For example, the charger body 120 and the base plate 110 may be detachably connected by means of a snap connection, a buckle connection, or a bolt connection.

[0055] The bottom plate 110 may have a mounting hole 111, which may be used to connect to the vehicle controller 200, so that the on-board charger 100 can be detachably connected to the vehicle controller 200 through the mounting hole 111. For example, the on-board charger 100 and the vehicle controller 200 may be detachably connected by bolts. Figure 2 and Figure 3As shown, the vehicle controller 200 may include a housing 210 , and the housing 210 may have a receiving cavity 211 . The on-board charger 100 may be located in the receiving cavity 211 of the housing 210 of the vehicle controller 200 and be detachably connected to the housing 210 .

[0056] For example, a threaded hole may be provided on the bottom wall of the housing 210 of the vehicle controller 200, and the mounting hole 111 on the bottom plate 110 of the vehicle charger 100 may be aligned with the threaded hole on the bottom wall of the vehicle controller 200. Bolt fasteners may pass through the mounting hole 111 on the bottom plate 110 and be screwed into the threaded hole on the bottom wall of the vehicle controller 200, so that the bottom plate 110 and the bottom wall are connected by the bolt fasteners, thereby making the vehicle charger 100 and the vehicle controller 200 detachably connected.

[0057] When the on-board charger 100 fails and needs to be repaired, the base plate 110 of the on-board charger 100 can be removed from the vehicle controller 200 to repair or replace the on-board charger 100. This can improve the convenience of repairing or replacing the on-board charger 100 and effectively improve the flexibility of using the on-board charger 100.

[0058] Among them, the on-board charger 100 is located in the shell 210 of the vehicle controller 200, and can share a shell 210 with the vehicle controller 200. In this way, there is no need to set the shell 210 in the on-board charger 100. It is only necessary to set the bottom plate 110 to connect with the shell 210 connected to the vehicle controller 200. The upper end cover of the on-board charger 100, the side wall of the lower shell 210 and other structures can be omitted, which can effectively reduce the structure of the on-board charger 100 and reduce the weight of the on-board charger 100, thereby effectively realizing the lightweight design of the on-board charger 100 and effectively reducing the material cost of the on-board charger.

[0059] Figure 4 A schematic diagram of the structure of a vehicle charger provided in an embodiment of the present application with the charger body removed.

[0060] See also Figure 4 As shown, the on-board charger 100 may further include a cooling pipeline 130 , which may be located on and connected to the base plate 110 , may contain a coolant, and the charger body may be distributed around the cooling pipeline 130 .

[0061] For example, the charger body 120 may include a circuit board and electronic components such as capacitors and inductors located on the circuit board. The circuit board may be located on the cooling pipe 130 , the electronic components may be located on a side of the circuit board facing the cooling pipe 130 , and the various electronic components may be dispersed around the cooling pipe 130 .

[0062] The coolant can flow in the cooling pipe 130 to achieve heat transfer. The charger body 120 can generate heat during operation, and the heat can be transferred to the coolant through the cooling pipe 130 to dissipate heat and cool down through the coolant. This can effectively reduce or avoid the charger body 120 being affected by excessive temperature and affecting its normal operation, which helps to improve the reliability and stability of the on-board charger 100.

[0063] Continue to see Figure 4 As shown, the cooling circuit 130 can be surrounded to form a first receiving groove 131, and the first receiving groove 131 can have a first thermally conductive adhesive (not shown in the figure), and at least a portion of the charger body 120 can be buried in the first thermally conductive adhesive. For example, the electronic components in the circuit board that are opposite to the first receiving groove 131 can extend into the thermally conductive adhesive groove. The first thermally conductive adhesive can improve the conduction of heat, so that the heat emitted by the electronic components located in the first receiving groove 131 can be transmitted to the cooling circuit 130 through the first thermally conductive adhesive, so as to dissipate the heat through the coolant in the cooling circuit 130, which helps to effectively improve the heat dissipation effect of the charger body 120 and further improve the reliability and stability of the charger.

[0064] Continue to see Figure 4 As shown, the on-board charger may further include a first baffle 140, which may be surrounded to form a second receiving groove 141, and the second receiving groove 141 may contain a second thermally conductive adhesive (not shown in the figure), and at least one end of a portion of the charger body 120 may extend into the second thermally conductive adhesive. The heat generated during the operation of the charger body 120 may also be conducted to the second thermally conductive adhesive through the end, so as to dissipate the heat outward through the second thermally conductive adhesive, thereby achieving heat dissipation and cooling of the charger body 120.

[0065] Continue to see Figure 4 As shown, the on-board charger 100 may further include a second baffle 150, which may be located on the bottom plate 110 and connected to the bottom plate 110. The cooling line 130 may be located between the second baffle 150 and the first baffle 140. The second baffle 150 may be arranged to form a third receiving groove 151. The third receiving groove 151 may contain a third thermally conductive adhesive, and at least one end of a portion of the charger body 120 may extend into the third thermally conductive adhesive. The heat generated during the operation of the charger body 120 may also be conducted to the third thermally conductive adhesive through the end portion, so as to dissipate the heat outward through the third thermally conductive adhesive, thereby achieving heat dissipation and cooling of the charger body 120.

[0066] The number of the third receiving grooves 151 can be multiple, and the shapes of the respective receiving grooves can be different. For example, as shown in the figure, the number of the third receiving grooves 151 can be four, one of the four receiving grooves can be rectangular, and the shapes of the remaining three receiving grooves can be circular, so as to meet the heat dissipation requirements of components of different shapes in the charger body 120.

[0067] Continue to see Figure 4 As shown, the on-board charger 100 may further include a plurality of first connecting posts 160, which may be distributed on both sides of the first receiving groove 131, and the first connecting posts 160 may be located at the edge of the bottom plate 110. A first connecting hole 161 may be provided on the first connecting post 160, and the charger body 120 may be connected to the first connecting post 160 through the first connecting hole 161.

[0068] For example, the charger body 120 and the first connecting column 160 can be connected by bolt fasteners, and the charger body 120 can have a mounting hole 111 that matches the first connecting hole 161, and the mounting hole 111 can be aligned with the first connecting hole 161. The bolt fastener can pass through the mounting hole 111 on the charger body 120 and be screwed into the first connecting hole 161. So that the charger body 120 can be connected to the first connecting column 160 by the bolt fastener. The bolt connection is easy to operate and reliable, which can effectively improve the firmness and reliability of the connection between the charger body 120 and the base plate 110. Moreover, it can also facilitate the disassembly of the charger body 120.

[0069] Continue to see Figure 4 As shown, the on-board charger 100 may further include a second connecting column 170, which may be disposed around the outer periphery of the cooling pipe 130 and connected to the cooling pipe 130. The second connecting column 170 may be provided with a second connecting hole 171, and the charger body 120 may be connected to the second connecting column 170 through the second connecting hole 171.

[0070] For example, the charger body 120 and the second connection column 170 can also be connected by bolt fasteners, and the charger body 120 can have a mounting hole 111 that matches the second connection hole 171, and the mounting hole 111 can be aligned with the second connection hole 171. The bolt fastener can pass through the mounting hole 111 on the charger body 120 and screw into the second connection hole 171. So that the charger body 120 can be connected to the second connection column 170 by the bolt fastener. In this way, the firmness and reliability of the connection between the charger body 120 and the base plate 110 can be further improved, and the overall structural stability of the on-board charger 100 can be improved.

[0072] See also Figure 5 As shown, the on-board charger 100 may further include a water inlet 180 and a water outlet 190, which may be located on the side of the bottom plate 110 facing away from the cooling pipeline 130, and the water inlet 180 and the water outlet 190 may be connected to the cooling pipeline 130. The coolant may flow from the water inlet 180 into the cooling pipeline 130, and then flow out from the water outlet 190 to achieve heat conduction, thereby achieving heat dissipation and cooling of the on-board charger 100, and improving the reliability and stability of the on-board charger 100.
