Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a PCB control board and a charging gun. Background Art

[0002] At present, the charging guns for new energy electric vehicles mainly include mode 2 charging guns and mode 3 AC charging guns. Among them, the mode 2 charging gun is also called the mode 2 AC charging gun. It is a household charging gun that uses a household power supply for charging. Generally, the mode 2 charging gun cable will have a control box in the middle.

[0003] However, the existing Mode 2 charging gun products do not have a separate charging control box, but the charging control box is set inside the gun body of the Mode 2 charging gun product, resulting in the shell design of the existing Mode 2 charging gun being a double-cavity structure or a single-cavity front and rear shell structure. For the charging gun shell with a double-cavity structure, the charging gun shell has two cavities, one upper and one lower. The lower cavity is used to integrate the control board, and the upper cavity is used as a handshake handle. The structure of the entire gun is relatively complex, the size is large, and the assembly is complex. For the charging gun shell with a single-cavity front and rear shell structure, the control board is integrated into the outer shell at the gun head end. Since the gun head itself has a certain length, the control board itself also has a certain length. When the control board is integrated into the outer shell at the gun head end, the gun head end shell is longer. At the same time, the tail of the charging gun shell of this type of structure is usually provided with a handle, and the internal space of the shell at the handle position is vacant, which causes the overall size of the charging gun to be longer, and the top is heavy, the appearance is not coordinated, the internal structure of the shell is complex, and charging failures are prone to occur.

[0004] In summary, the existing Mode 2 charging gun has technical problems such as being too long, having an inconsistent appearance, having idle space inside the charging gun housing, and having a complex internal structure of the charging gun housing. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a PCB control board.

[0006] It should be noted that PCB means printed circuit board, which is translated into Chinese as "printed circuit board".

[0007] The PCB control board is in the shape of an elongated strip and includes a narrow area and a wide area. The wide area and the narrow area are of an integrated design, and the width of the narrow area is smaller than the width of the wide area. The wide area includes a protruding area, and the protruding area is arranged at one end of the wide area away from the narrow area.

[0008] It should be noted that in the field of charging gun technology, the shape of the charging gun is subject to the high-power transmission process and the comfort of human hand holding, and it is often necessary to gradually thicken from the input end to the output end. Therefore, the PCB control board in the utility model is also to meet the above needs, and its shape is set to a wide area and a narrow area to meet the design that the shape of the charging gun gradually becomes thicker from the input end to the output end.

[0009] It should be noted that the wide area can be defined as the output end of the entire PCB control board, which is used to contact and charge the device to be charged. The narrow area can be defined as the input end of the entire PCB control board, which is used to access the mains.

[0010] It should be noted that the device to be charged may be an electric car, an electric bicycle, or other device.

[0011] Specifically, the width difference between the narrow area and the wide area ranges from 5 mm to 15 mm.

[0012] It should be noted that the difference in width between the narrow area and the wide area is in the range of 8 mm to 15 mm, which means that the narrow area is narrower than the wide area, and the difference in width between the two is between 8 mm and 15 mm. The difference in width is obtained through multiple experiments. If the difference in width between the two is too large, it may be difficult to set the transition zone between the two, and waste materials in the transition zone; if the difference in width between the two is too small, it will not be possible to meet the design that the shape of the charging gun gradually becomes thicker from the input end to the output end.

[0013] Specifically, the end of the wide area away from the narrow area also includes: a side ear area, the side ear area includes: a first side ear and a second side ear, the second side ear is arranged at an interval from the first side ear; the protruding area is arranged between the first side ear and the second side ear.

[0014] It should be noted that the first side ear and the second side ear are located at the output end of the charging gun. During use, the first side ear and the second side ear can be inserted into the gun head, so that the positioning of the gun head and the PCB control board is more accurate, and technical problems such as poor contact are not likely to occur.

[0015] Specifically, the wide area is provided with a relay, an output line wiring hole and a switch module; the relay and the switch module are electrically connected; the switch module, the output line wiring hole and the relay are arranged in sequence and gradually approach the narrow area.

[0016] It should be noted that the wide area is also provided with relatively high electronic components such as leakage transformer, current transformer, and point voltage transformer. Since the above electronic components are relatively high, they are arranged in the wide area, and they can be arranged in the thicker shell of the charging gun.

[0017] It should be further explained that, since the first side ear and the second side ear are in contact with the gun head, the positioning accuracy and firmness between the gun head and the PCB control board are increased. At the same time, since the protruding area is arranged between the first side ear and the second side ear, and the switch module is arranged in the protruding area, not only the switch control of the PCB control board is made more precise, but also the stroke of the switch control is improved.

[0018] It should be further explained that the switch module is arranged in the protruding area, so that the switch module can extend into the internal area of ​​the gun head, which greatly utilizes the space inside the gun head and simplifies the assembly process of the switch module.

[0019] Specifically, the relay and the switch module are distributed on different surfaces of the PCB control board.

[0020] It should be noted that the PCB control board includes a top surface and a bottom surface, the relay is arranged on the top surface, and the switch module is arranged on the bottom surface.

[0021] Specifically, the narrow area is provided with a power module, a capacitor module and an input wiring hole; wherein the input wiring hole is close to the wide area, and the power module and the capacitor module are far away from the wide area.

[0022] It should be noted that the power module and the capacitor module are arranged on the same side of the input wiring hole, and the same side here can be the same side away from or close to the wide area. The beneficial effect of arranging the power module and the capacitor module on the same side of the input wiring hole is that space can be reserved for the input line of the power supply to avoid interference, squeezing and other problems.

[0023] Specifically, the narrow area is further provided with an LED lamp, and the position of the LED lamp is far away from the wide area.

[0024] Specifically, the LED lamp and the power module are arranged on different surfaces of the PCB control board.

[0025] It should be noted that the position of the LED lamp is far away from the wide area and belongs to the low voltage area, the voltage around it is low, and it is set on the bottom surface of the PCB control board. The probability of the LED lamp being disturbed by the current is small, and it is more convenient to spread the light source when it is set on the bottom surface.

[0026] It should be noted that LED is the abbreviation of Light Emitting Diode, which is a semiconductor light-emitting material. When a forward voltage is applied to both ends, the carriers in the semiconductor recombine to cause photon emission and generate light. LED can directly emit red, yellow, blue, green, cyan, orange, purple, and white light.

[0027] Specifically, the utility model also provides a charging gun, including:

[0028] The PCB control board;

[0029] A housing, wherein the housing is disposed on the periphery of the PCB control board; the housing forms a receiving space, and the PCB control board is disposed in the receiving space;

[0030] A cable is inserted into the receiving space and is electrically connected to the PCB control board.

[0031] Compared with the prior art, the utility model has the following beneficial effects: the PCB control board is in the shape of a long strip, and the PCB control board includes a narrow area and a wide area, the wide area and the narrow area are integrated, and the width of the narrow area is smaller than the width of the wide area; the wide area includes a protruding area, and the protruding area is arranged at one end of the wide area away from the narrow area. In order to meet the above needs, the PCB control board of the utility model is also set to have a wide area and a narrow area to meet the design that the shape of the charging gun gradually becomes thicker from the input end to the output end.

[0047] The PCB control board includes a narrow area and a wide area, wherein the narrow area and the wide area are integrated, and the width of the narrow area is smaller than the width of the wide area. Figure 4 As shown, the wide area is connected to the gun head 11 , the narrow area is connected to the cable 10 , and there is a transition area between the narrow area and the wide area.
